CHICAGO – Postmenopausal hormone therapy with conjugated equine estrogens (CEEs) was not associated with overall sustained benefit or risk to cognitive function when given to women ages 50 to 55 years, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

The Women’s Health Initiative Memory Study (WHIMS) demonstrated that postmenopausal hormone therapy with CEEs, when prescribed to women 65 years and older, caused deficits in global and domain-specific cognitive functioning.

 

The Women’s Health Initiative Memory Study of Younger Women (WHIMSY) tested whether prescribing CEE-based hormone therapy to postmenopausal women ages 50 to 55 years had longer-term effects on cognitive function. The study by Mark A. Espeland, Ph.D., of the Wake Forest School of Medicine, Winston-Salem, N.C., and colleagues presents primary findings from this study.

 

“Global cognitive function scores from women who had been assigned to CEE-based therapies were similar to those from women assigned to placebo,” according to the study results. “Similarly, no overall differences were found for any individual cognitive domain.”

 

The study included 1,326 postmenopausal women, who had started treatment in two randomized placebo-controlled clinical trial of hormone therapy when they were ages 50 to 55 years. The clinical trials the women participated in compared 0.625mg CEE with or without 2.5mg medroxyprogesterone acetate over an average of seven years.

 

“Our findings provide reassurance that CEE-based therapies when administered to women earlier in the postmenopausal period do not seem to convey long-term adverse consequences for cognitive function. Although we cannot rule out acute benefits or harm, these do not appear to be present to any degree a mean of seven years after cessation of therapy. One exception may be for minor longer-term disturbances of verbal fluency for women prescribed CEE alone; however this may be a chance finding,” the authors conclude.

Commentary: Hormone Therapy in Younger Women, Cognitive Health

 

In an invited commentary, Francine Grodstein, Sc.D., of Brigham and Women’s Hospital, Boston, writes: “Approximately 10 years ago, the Women’s Health Initiative Memory Study (WHIMS) found that postmenopausal hormone therapy in older women caused nearly two-fold increases in dementia risk, worse rates of cognitive decline over time, and decreased brain volume on magnetic resonance imaging, compared with placebo treatment.”

 

“In the article by Espeland et al, WHIMS investigators report new results from the Women’s Health Initiative Memory Study in Younger Women (WHIMSY). The WHIMSY trial cleverly leverages 1,272 participants from the Women’s Health Initiative who were aged 50 to 55 years when they were originally assigned to hormone therapy or placebo and reports findings from cognitive assessments administered a mean 7.2 years after treatment was halted,” Grodstein continues.

 

“In these younger women, reassuringly, cognitive function appears similar in those who had been given hormone therapy vs. placebo; that is, there is no evidence in WHIMSY of substantially worse cognitive function associated with hormone use at younger ages,” Grodstein concludes.

Prenatal Smoke Exposure Associated with Adolescent Hearing Loss

EMBARGOED FOR RELEASE: 3 P.M. (CT), THURSDAY, JUNE 20, 2013

Media Advisory: To contact author Michael Weitzman, M.D., call Lorinda Klein at 212-404-3533 or email Lorindaann.Klein@nyumc.org.


CHICAGO – Prenatal smoke exposure was associated with hearing loss in a study of adolescents, which suggests that in utero exposure to tobacco smoke could be harmful to the auditory system, according to a study published Online First by JAMA Otolaryngology–Head & Neck Surgery.

 

Exposure to second-hand smoke (SHS) is a public health problem and exposure to tobacco smoke from in utero to adulthood is associated with a wide variety of health problems, the authors write in the study background.

 

Michael Weitzman, M.D., of the New York University School of Medicine, and colleagues studied data for 964 adolescents (ages 12 to 15 years) from the National Health and Nutrition Examination Survey 2005-2006 to determine whether exposure to prenatal tobacco smoke was associated with sensorineural hearing loss in adolescents.

 

Parents confirmed prenatal smoke exposure in about 16 percent of the 964 adolescents. Prenatal smoke exposure was associated with higher pure-tone hearing thresholds and an almost three-fold increase in the odds of unilateral low-frequency hearing loss, according to study results.

 

“The actual extent of hearing loss associated with prenatal smoke exposure in this study seems relatively modest; the largest difference in pure-tone hearing threshold between exposed and unexposed adolescents is less than 3 decibels, and most of the hearing loss is mild. However, an almost 3-fold increased odds of unilateral hearing loss in adolescents with prenatal smoke exposure is worrisome for many reasons,” the study concludes.

JAMA Dermatology Study Highlights

Although overall mortality rates due to single primary melanomas (SPMs) and multiple primary melanomas (MPMs) appear to be similar, relative mortality for thicker SPM appears to be greater than that for thicker MPM, according to a study by Anne Kricker, Ph.D., of the University of Sydney, Australia and colleagues. (Online First)

 

A total of 2,372 patients with SPM and 1,206 patients with MPM participated in the study. Melanoma thickness was the main determinant of mortality; other independent predictors were ulceration, mitoses (cell division), and scalp location. After adjustment for these factors, the researchers found little difference in mortality rates between MPM and SPM. Thicker SPM, however, had higher mortality rates than thicker MPM, according to the study results.

 

“We found no strong evidence of a difference in survival between SPM and MPM patients despite the evidence of other researchers and suggestions that MPM may have a less aggressive biology than SPM…to our knowledge, we report for the first time a greater increase in the risk of death with increasing tumor thickness for SPM than for MPM,” the authors conclude.

Smoking Cessation Associated With Reduced Postoperative Complications After Major Surgery

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, JUNE 19, 2013

Media Advisory: To contact corresponding author Faek R. Jamali, M.D., email fj03@aub.edu.lb.

 

JAMA Surgery Study Highlights

Smoking cessation at least one year before major surgery eliminates the increased risk of postoperative mortality and decreases the risk of arterial and respiratory events evident in current smokers, according to a study by Khaled M. Musallam, M.D., Ph.D., of the American University of Beirut Medical Center, Lebanon and colleagues. (Online First)

 

 

A total of 125,192 current and 78,763 past smokers from the American College of Surgeons National Surgical Quality Improvement Program database who underwent a major surgery were included in the study sample. The study authors measured for 30-day postoperative death, arterial (major) events, venous events, and respiratory events.

 

Increased odds of postoperative mortality were noted in current smokers. When the authors compared current and past smokers, adjusted odds ratios were higher in the current smokers for arterial events and respiratory events, but there were no difference for venous events. The increased adjusted odds of mortality in current smokers were evident from a smoking history of less than 10 pack-years, whereas the relationship between smoking and arterial and respiratory events was incremental with increased pack-years.

 

“These findings should be carried forward to evaluate the value and cost-effectiveness of intervention in this setting. Our study should increase awareness of the detrimental effects of smoking—and the benefits of its cessation—on morbidity and mortality in the surgical setting,” the authors conclude.

Prenatal Exposure to Maternal Cigarette Smoking Associated With Altered Reward Processing and Anticipation

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, JUNE 19, 2013

Media Advisory: To contact corresponding author Michael N. Smolka, M.D., email Michael.Smolka@tu-dresden.de.

 

JAMA Psychiatry Study Highlights

Whether adolescents with prenatal exposure to maternal cigarette smoking differ from their nonexposed peers in the response part of their brain to the anticipation or the receipt of a reward was examined in a study by Kathrin U. Müller, Dipl-Psych, of Technische Universität Dresden, Germany, and colleagues.

 

The researchers assessed 177 adolescents with prenatal exposure to maternal cigarette smoking and 177 nonexposued peers (age range, 13-15 years) matched by sex, maternal educational level, and imaging site. Response to reward was measured in the ventral striatum area of the brain by using functional magnetic resonance imaging.

 

In prenatally exposed adolescents, the authors reported observing a weaker response in the ventral striatum during reward anticipation compared with their nonexposed peers. No differences were found regarding the responsivity of the ventral striatum to the receipt of a reward.

 

“The weaker responsivity of the ventral striatum to regard anticipation in prenatally exposed adolescents may represent a risk factor for substance use and development of addiction later in life. This result highlights the need for education and preventive measures to reduce smoking during pregnancy,” the study concludes.

Screening Colonoscopy Associated With Increased Survival Duration and Rates For Patients With Colon Cancer

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, JUNE 19, 2013

Media Advisory: To contact corresponding author David L. Berger, M.D., call Katie Marquedant at 617-726-0337 or email KMarquedant@Partners.org.


CHICAGO – Patients with colon cancer identified on screening colonoscopy appear to have lower-stage disease on presentation and better outcomes independent of their staging, according to a report published Online First by JAMA Surgery, a JAMA Network publication.

 

Since their introduction in 2000, National Institutes of Health—recommended screening colonoscopy guidelines seemingly have consistently decreased overall rates of colorectal cancer in the United States.

 

Ramzi Amri, M.Sc., and colleagues of Massachusetts General Hospital and Harvard Medical School, Boston, examined the association of screening colonoscopy with outcomes of colon cancer surgery by reviewing differences in staging, disease-free interval, risk of recurrence, and survival and to identify whether diagnosis through screening was associated with long-term outcomes independent of staging.

 

Patients not diagnosed through screening were at risk for having more invasive tumors, nodal disease, and metastatic disease on presentation. In follow-up, these patients had higher death rates, and recurrence rates as well as shorter survival and disease-free intervals. After controlling for staging and baseline characteristics, the authors found that death rate and survival duration were better stage for stage with diagnosis through screening. Death and metastasis rates also remained lower among patients with tumors without nodal or metastatic spread.

 

Compliance to screening colonoscopy guidelines can play an important role in prolonging longevity, improving quality of life, and reducing health care costs through early detection of colon cancer,” the authors conclude.

Study Finds Need for Improvement on State Health Care Price Websites

“With rising health care costs and 30 percent of privately insured adults enrolled in high-deductible health care plans, calls for greater health care price transparency are increasing. In response, health plans, consumer groups, and state governments are increasingly reporting health care prices. Despite recognition that price information must be relevant, accurate, and usable to improve the value of patients’ out-of-pocket expenditures, and the potential for this reporting to affect health care organizations and prices, there are no data on what kind of price information is being reported,” writes Jeffrey T. Kullgren, M.D., M.S., M.P.H., of the Veterans Affairs Ann Arbor Healthcare System, Ann Arbor, Mich., and colleagues.

As reported in a Research Letter, the authors conducted a study to examine the characteristics of state health care price websites and identify opportunities for improving the utility of this information. Systematic Internet searches were conducted between January and May 2012 to identify publicly available, patient-oriented websites hosted by a state specific institution (e.g., a state government agency or hospital association) that enabled patients to estimate or compare prices for health care services in that state. For each website, a number of factors were examined, including classifying the reporting organization, year reporting started, patient information used to generate price estimates, and types of services for which price estimates were provided.

Among the findings and recommendations of the researchers: “Greater relevance to patients could be realized by focusing information on services that are predictable, nonurgent, and subject to deductibles (e.g., routine outpatient care for chronic diseases) rather than services that are unpredictable, emergent, or would exceed most deductibles (e.g., hospitalizations for life-threatening conditions). Accuracy could be improved by reporting allowable charges for full episodes of care (i.e., aggregate prices for health care services that include all fees such as facility, professional, and other fees). Usability could be enhanced by presenting quality information alongside prices where applicable, as opposed to reporting just one type of data needed to assess value.”

Building Trust in the Power of ‘Big Data’ Research to Serve the Public Good

According to a recent report from the Institute of Medicine’s (IOM) Clinical Effectiveness Research Innovation Collaborative (CERIC), routinely collected data “provide great potential for extracting useful knowledge to achieve the ‘triple aim’ in health care— better care for individuals, better care for all, and greater value for dollars spent,” writes Eric B. Larson, M.D., M.P.H., of the Group Health Research Institute, Seattle.

“Through advances in health information technology, the needed tools are available to prevent future harm, eliminate waste, and learn with better certainty which treatments are most effective. This can be accomplished without risking patient privacy or proprietary business interests. By overcoming cultural impediments based on outdated ideas about the collection and use of everyday health care information, it will be possible to fulfill the lOM’s vision of an integrated, comprehensive health care system using routinely collected health care data for continual learning that seamlessly serves individual patients and the public good.”

Group-Based Child Care Appears to be Associated with Reduced Risk for Emotional Problems in Children

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, JUNE 19, 2013

Media Advisory: To contact author Catherine M. Herba, Ph.D., email herba.catherine@uqam.ca


CHICAGO – Regulated group-based child care appears to be associated with reduced risk for emotional problems among children of mothers with maternal depressive symptoms, according to a study published Online First by JAMA Psychiatry, a JAMA Network publication.

 

Children of depressed mothers are at increased risk of mental health problems. Researchers want to better understand how maternal depressive symptoms (MDSs) are associated with child outcome over time, the authors write in the study background.

 

Catherine M. Herba, Ph.D., of the Université du Québec á Montréal, Canada, and colleagues sought to determine whether early child care could moderate associations between MDSs and child emotional problems (EPs), separation anxiety symptoms and societal withdrawal symptoms (SWS) during the preschool period.

 

The population-based study included 1,759 children repeatedly assessed between the ages of 5 months and 5 years.

 

“We found that children exposed to MDSs during the preschool years were at elevated risk for internalizing symptoms but that their risk for EPs and SWSs was significantly reduced if they received early child care services. Given that most of today’s children experience child care during the preschool years, child care could potentially serve as a public health intervention strategy for high-risk children,” the study notes.

 

Among children of mothers with elevated MDSs, there were reduced risks for EPs and SWSs for those entering child care early or entering child care late compared with those children who remained in the care of their mothers. Children of mothers with elevated MDSs who received group-based child care also had lower risk for EPs than those who remained in maternal care or those who were cared for by a relative or babysitter, the results also indicate.

 

“Regulated child care services may represent an intervention that buffers the negative effect of MDSs on children’s EPs and SWSs,” the study concludes.

Study Evaluates Procedures for Diagnosing Sarcoidosis

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 18, 2013

Media Advisory: To contact corresponding author Jouke T. Annema, M.D., Ph.D., email j.t.annema@amc.nl.


CHICAGO – Among patients with suspected stage I/II pulmonary sarcoidosis who were undergoing confirmation of the condition via tissue sampling, the use of the procedure known as endosonographic nodal aspiration compared with bronchoscopic biopsy, the current diagnostic standard, resulted in greater diagnostic yield, according to a study in the June 19 issue of JAMA.

Sarcoidosis, a disease that causes granulomas (usually small masses) due to chronic inflammation in body tissues, has an estimated lifetime risk of 1 percent to 2 percent. The incidence of sarcoidosis in the United States is estimated at up to 40 cases per 100,000, and sarcoidosis-related mortality is increasing, according to background information in the article. The disease affects the lungs and intrathoracic lymph nodes in almost all patients. Bronchoscopy with transbronchial lung biopsies has moderate sensitivity in assessing granulomas. Endosonography with intrathoracic nodal aspiration (removal of tissue with a needle using ultrasound guidance) appears to be a promising diagnostic technique.

Martin B. von Bartheld, M.D., of Leiden University Medical Center, Leiden, the Netherlands, and colleagues conducted a study to evaluate the diagnostic yield of bronchoscopy vs. endosonography in the diagnosis of stage I/II sarcoidosis. The randomized trial was conducted at 14 centers in 6 countries between March 2009 and November 2011 and included 304 patients with suspected pulmonary sarcoidosis (stage I/II) in whom tissue confirmation of noncaseating (not exhibiting caseation [necrosis in the tissue]) granulomas was indicated.

Patients underwent either bronchoscopy with transbronchial and endobronchial lung biopsies or endosonography (esophageal or endobronchial ultrasonography) with aspiration of intrathoracic lymph nodes. The primary measured outcome was the diagnostic yield for detecting noncaseating granulomas in patients with a final diagnosis of sarcoid­osis.

A total of 149 patients were randomized to bronchoscopy and 155 to endosonography. The researchers found that granulomas were found significantly more often at endosonography than bronchoscopy (114/154 [74 percent;] vs. 72/149 [48 percent]). The diagnostic yield to detect granulomas for endosonography vs. bronchoscopy was 80 percent vs. 53 percent.

“For stage I sarcoidosis, the diagnostic yield of bronchoscopy was 38 percent compared with 66 percent for stage II. For endosonography, diagnostic yield for stage I was 84 percent compared with 77 percent for stage II,” the authors write.

Two serious adverse events occurred in the bronchoscopy group and 1 in the endosonography group; all patients recovered completely.

“How will the outcomes of this study affect future diagnostic strategies for patients with suspected sarcoidosis? Whether tissue confirmation of granulomas is indicated should be critically assessed in light of recent improvements in computed tomography-thorax imaging. For patients who require tissue sampling either to confirm sarcoidosis before treatment or to exclude similar presenting diseases such as tuberculosis and lymphoma, the outcomes of this study indicate that endosonographic evaluation is likely to have the highest diagnostic yield,” the researchers conclude.

Markers of Beta-Cell Dysfunction Associated With High Rate of Progression to Type 1 Diabetes

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 18, 2013

Media Advisory: To contact Anette G. Ziegler, M.D., email anette-g.ziegler@helmholtz-muenchen.de. To contact editorial co-author Jay S. Skyler, M.D., call Lisa Worley at 305-243-5184 or email lworley2@med.miami.edu.


CHICAGO – The majority of children at risk of type 1 diabetes who developed 2 or more diabetes-related autoantibodies developed type 1 diabetes within 15 years, findings that highlight the need for research into finding interventions to stop the development of multiple islet autoantibodies, according to a study in the June 19 issue of JAMA.

“Type 1 diabetes is a chronic autoimmune disease that often manifests during childhood and adolescence. The lifelong requirement for insulin injections and the many complications that follow the diagnosis can be difficult for those affected. Type 1 diabetes usually has a preclinical phase that can be identified by the presence of autoantibodies to antigens of the pancreatic beta cells,” according to background information in the article. The rate of progression to diabetes after seroconversion to islet autoantibodies is uncertain.

Anette G. Ziegler, M.D., of Helmholtz Zentrum Munchen, Neuherberg, Germany, and colleagues conducted a study to estimate rates of progression to type 1 diabetes and associated characteristics based on islet autoantibody status. For the study, data were pooled from prospective cohort studies performed in Colorado (recruitment, 1993-2006), Finland (recruitment, 1994-2009), and Germany (recruitment, 1989-2006) examining children genetically at risk for type 1 diabetes for the development of insulin autoantibodies, glutamic acid decarboxylase 65 (GAD65) autoantibodies, insulinoma antigen 2 (IA2) autoantibodies, and diabetes. Participants were all children recruited and followed up in the 3 studies (Colorado, 1,962; Finland, 8,597; Germany, 2,818). Follow-up assessment in each study was concluded by July 2012.

The researchers found that progression to type 1 diabetes at 10-year follow-up after islet autoantibody seroconversion in 585 children with multiple islet autoantibodies was 69.7 percent, and in 474 children with a single islet autoantibody was 14.5 percent. Risk of diabetes in children who had no islet autoantibodies was 0.4 percent by the age of 15 years.

A total of 355 children (60.7 percent) with multiple islet autoantibodies progressed to diabetes at a median (midpoint) follow-up time after seroconversion of 3.5 years, and a median age of 6.1 years. Progression to diabetes after seroconversion was 43.5 percent at 5-year follow-up, 69.7 percent at the 10-year follow-up, and 84.2 percent at the 15-year follow-up.

Analysis indicated that more rapid progression to diabetes after seroconversion was associated with younger age at seroconversion (younger than age 3 years [10-year risk, 74.9 percent] vs. children 3 years or older [60.9 percent]); and female sex (10-year risk of 74.8 percent for girls vs. 65.7 percent for boys).

“These data show that the detection of multiple islet autoantibodies in children who are genetically at risk marks a preclinical stage of type 1 diabetes. … Thus, the development of multiple islet autoantibodies in children predicts type 1 diabetes,” the authors write. “Future prevention studies should focus on this high-risk population.”

Editorial: The Evolution of Type 1 Diabetes

Jay S. Skyler, M.D., and Jay M. Sosenko, M.D., of the University of Miami Miller School of Medicine, write in an accompanying editorial that the nearly inevitable progression of individuals from seropositivity to type 1 diabetes (T1D) in the current report by Ziegler et al “serves to raise the question of whether the definition of T1D needs updating, perhaps broadening to include a prediabetic state.”

“Current criteria for overt diabetes are based on what is used for type 2 diabetes. Yet the sequence of events in diabetes development suggests it is possible to modify the definition at least to include individuals who are seropositive with either dysglycemia or a high T1D risk score. This would allow potential intervention with immunomodulatory therapies directed at preservation of beta-cell function measured by C-peptide. Data from the Diabetes Control and Complications Trial have demonstrated that preservation of C-peptide results in reduced risk of severe hypoglycemia and of progression of retinopathy and nephropathy.”

CHICAGO – Among children with juvenile idiopathic arthritis (JIA) who had undergone primary immunization, the use of a measles-mumps-rubella (MMR) booster compared with no booster did not result in worse JIA disease activity, according to a study in the June 19 issue of JAMA.

“Juvenile idiopathic arthritis is the most common childhood rheumatic disease, with a prevalence between 16 and 150 per 100,000. Patients with JIA may be susceptible to infections through the immunosuppressive effect of their disease or its treatment. Preventing infections in patients with JIA requires effective and safe vaccinations that induce protective immune responses, have no severe adverse effects, and do not affect JIA disease activity. The live attenuated MMR vaccine is administered to children worldwide via national immunization programs. In immunocompromised patients, concern exists about the safety of live attenuated vaccines given the theoretical risk of enhanced replication of the attenuated pathogens in these patients. The safety of MMR vaccination in particular has been questioned in patients with JIA because the rubella component has been linked to the induction of arthritis in small uncontrolled studies,” according to background information in the article.

Marloes W. Heijstek, M.D., of the University Medical Center Utrecht, Wilhelmina Children’s Hospital, Utrecht, the Netherlands, and colleagues conducted a study to assess whether MMR booster vaccination affects disease activity in patients with JIA. The randomized trial included 137 patients with JIA 4 to 9 years of age who were recruited from 5 academic hospitals in the Netherlands between May 2008 and July 2011. Patients were randomly assigned to receive MMR booster vaccination (n=68) or no vaccination (control group; n=69). Disease activity was measured by the Juvenile Arthritis Disease Activity Score (JADAS-27), ranging from 0 (no activity) to 57 (high activity).

The researchers found that the average JADAS-27 during the total follow-up period did not differ significantly between 63 revaccinated patients (JADAS-27, 2.8) and 68 controls (JADAS-27, 2.4). The average number of flares per patient did not differ significantly between the MMR booster group (0.44) and the control group (0.34), nor did the percentage of patients with 1 or more flares during follow-up.

All revaccinated patients were seroprotected against measles and rubella after vaccination. At 12 months, seroprotection rates were higher in revaccinated patients vs. controls (measles, 100 percent vs. 92 percent; mumps, 97 percent vs. 81 percent; and rubella, 100 percent vs. 94 percent, respectively), and antibody concentrations were higher compared with controls against measles, mumps, and rubella.

“The safety of MMR vaccination has been questioned because disease flares have been described after MMR vaccination. Our trial does not show an effect of vaccination on disease activity,” the authors write.

“Larger studies are needed to assess MMR effects in patients using biologic agents.”

MRI Screening May Help Identify Spinal Infections From Contaminated Drug Injections

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 18, 2013

Media Advisory: To contact Anurag N. Malani, M.D., call Laura Blodgett at 734-712-4536 or email blodgetl@trinity-health.org. To contact editorial co-author Thomas F. Patterson, M.D., call Sheila Hotchkin at 210-567-3026 or email Hotchkin@uthscsa.edu.


CHICAGO – Magnetic resonance imaging (MRI) at the site of injection of a contaminated lot of a steroid drug to treat symptoms such as back pain resulted in earlier identification of patients with probable or confirmed fungal spinal or paraspinal infection, allowing early initiation of medical and surgical treatment, according to a study in the June 19 issue of JAMA.

“Fungal contamination of methylprednisolone [a steroid] prepared by a compounding pharmacy resulted in an unprecedented multistate outbreak of meningitis in the fall of 2012,” according to background information in the article. “Initially, these injections were complicated by meningitis. Within 6 weeks of the outbreak, meningitis became less frequent and localized spinal and paraspinal infections became the principal manifestations of contaminated steroid injections. In contrast to the relatively brief period in which meningitis cases appeared, a steady stream of spinal and paraspinal infections continue to present long after the injections were administered. Because patients received these injections to treat back pain or neuropathic symptoms, the presentation of a slowly developing spinal or paraspinal infection has been obscured.”

Anurag N. Malani, M.D., of St. Joseph Mercy Hospital, Ann Arbor, Mich., and colleagues conducted a study to determine if patients who had not presented for medical care but who had received contaminated methylprednisolone developed spinal or paraspinal infection at the injection site detected using contrast-enhanced MRI screening. There were 172 patients who had received an injection of methylprednisolone from a highly contaminated lot at a pain facility but had not presented for medical care related to adverse effects after the injection. Screening MRI was performed between November 2012 and April 2013.

Of the 172 patients screened, 36 (21 percent) had an abnormality in their MRI. Thirty-five of the 36 patients with abnormal MRIs met the Centers for Disease Control and Prevention (CDC) case definition for probable (17 patients) or confirmed (18 patients) fungal spinal or paraspinal infection. All 35 patients were treated with antifungal agents; 24 required surgical intervention.

“At the time of surgery, 17 of 24 patients (71 percent), including 5 patients who denied having symptoms, had laboratory evidence of fungal infection,” the authors write.

Data were obtained from 115 patients regarding the presence of new or worsening back or neck pain, radiculopathy, or lower-extremity weakness Thirty-five of the 115 patients (30 percent) had at least 1 of these symptoms.

“Our findings support obtaining contrast-enhanced MRI of the injection site in patients with persistent back pain even when their pain disorder has not worsened,” the researchers write. “A proactive outreach to patients receiving injections from a highly contaminated lot, especially lot No. 06292012@26, is needed. Magnetic resonance imaging may detect infection earlier in some patients, leading to more efficacious medical and surgical treatment and improved outcomes,” the researchers conclude.

Editorial: Real-world Experience in the Midst of an Exserohilum Meningitis Outbreak

“… Malani et al have demonstrated the possibility of largely asymptomatic fungal infection among patients previously exposed to injection with contaminated lots of methylprednisolone,” writes George R. Thompson III, M.D., of the University of California, Davis and colleagues in an accompanying editorial.

“These findings suggest MRI of the injection site may be an effective screening procedure in some patients but should not be widely adopted, particularly for patients who received peripheral joint injections, given the much lower attack rate. For patients who received spinal injections with steroids from an unknown lot number, MRI-based screening may be appropriate. Whether patients with normal initial MRI findings receive reimaging at a later date remains a difficult question in this evolving outbreak.”

Earlier Treatment Following Stroke Onset Associated With Reduced Risk of In-Hospital Death, Higher Rate of Discharge to Home

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 18, 2013

Media Advisory: To contact Jeffrey L. Saver, M.D., call Kim Irwin at 310-794-2262 or email kirwin@mednet.ucla.edu; or call Rachel Champeau at 310-794-2270 or email rchampeau@mednet.ucla.edu.


CHICAGO – In a study that included nearly 60,000 patients with acute ischemic stroke, thrombolytic treatment (to help dissolve a blood clot) that was started more rapidly after symptom onset was associated with reduced in-hospital mortality and intracranial hemorrhage and higher rates of independent walking ability at discharge and discharge to home, according to a study in the June 19 issue of JAMA.

“Intravenous (IV) tissue-type plasminogen activator (tPA) is a treatment of proven benefit for select patients with acute ischemic stroke as long as 4.5 hours after onset. Available evidence suggests a strong influence of time to therapy on the magnitude of treatment benefit,” according to background information in the article. Imaging studies show the volume of irreversibly injured tissue in acute cerebral ischemia expands rapidly over time. “However, modest sample sizes have limited characterization of the extent to which onset to treatment (OTT) time influences outcome; and the generalizability of findings to clinical practice is uncertain.”

Jeffrey L. Saver, M.D., of the David Geffen School of Medicine at UCLA, Los Angeles, and colleagues conducted a study to determine the association between time to treatment with intravenous thrombolysis and outcomes among patients with acute ischemic stroke. The study included data from 58,353 patients with acute ischemic stroke treated with tPA within 4.5 hours of symptom onset in 1,395 hospitals participating in the Get With The Guidelines-Stroke Program, April 2003 to March 2012. The median (midpoint) age of the patients was 72 years.

The median OTT time was 144 minutes, 9.3 percent had OTT time of 0 to 90 minutes, 77.2 percent had OTT time of 91 to 180 minutes, and 13.6 percent had OTT time of 181 to 270 minutes. Patient factors most strongly associated with shorter OTT included greater stroke severity, arrival by ambulance and arrival during regular hours. Overall, there were 5,142 (8.8 percent) in-hospital deaths, 2,873 (4.9 percent) patients had intracranial hemorrhage, 19,491 (33.4 percent) patients achieved independent ambulation (walking ability) at hospital discharge, and 22,541 (38.6 percent) patients were discharged to home.

The researchers found that for every 15-minute-faster interval of tPA therapy, mortality was less likely to occur, symptomatic intracranial hemorrhage was less likely to occur, independence in ambulation at discharge was more likely to occur, and discharge to home was more likely to occur. For patients treated in the first 90 minutes, compared with 181-270 minutes after onset, mortality was 26 percent less likely to occur, symptomatic intracranial hemorrhage was 28 percent less likely to occur, independence in ambulation at discharge was 51 percent more likely to occur, and discharge to home was 33 percent more likely to occur.

“These findings support intensive efforts to accelerate patient presentation and to streamline regional and hospital systems of acute stroke care to compress OTT times,” the authors conclude.

Study of Dietary Intervention Examines Proteins in Brain

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 17, 2013

CHICAGO – The lipidation states (or modifications) in certain proteins in the brain that are related to the development of Alzheimer disease appear to differ depending on genotype and cognitive diseases, and levels of these protein and peptides appear to be influenced by diet, according to a report published Online First by JAMA Neurology, a JAMA Network publication.

 

Sporadic Alzheimer disease (AD) is caused in part by the accumulation of β-amyloid (Αβ) peptides in the brain. These peptides can be bound to lipids or lipid carrier proteins, such as apolipoprotein E (ApoE), or be free in solution (lipid-depleted [LD] Αβ). Levels of LD Αβ are higher in the plasma of adults with AD, but less is known about these peptides in the cerebrospinal fluid (CSF), the authors write in the study background.

 

Angela J. Hanson, M.D., Veterans Affairs Puget Sound Health Care System and the University of Washington, Seattle, and colleagues studied 20 older adults with normal cognition (average age 69 years) and 27 older adults with amnestic mild cognitive impairment (average age 67 years).

 

The patients were randomized to a diet high in saturated fat content (45 percent energy from fat, greater than 25 percent saturated fat) with a high glycemic index or a diet low in saturated fat content (25 percent of energy from fat, less than 7 percent saturated fat) with a low glycemic index. The main outcomes the researchers measured were lipid depleted (LD) Αβ42 and Αβ40 and ApoE in cerebrospinal fluid.

 

Study results indicate that baseline levels of LD Αβ were greater for adults with mild cognitive impairment compared with adults with normal cognition. The authors also note that these findings were more apparent in adults with mild cognitive impairment and the Ɛ4 allele (a risk factor for AD), who had higher LD apolipoprotein E levels irrespective of cognitive diagnosis. Study results indicate that the diet low in saturated fat tended to decrease LD Αβ levels, whereas the diet high in saturated fat increased these fractions.

 

The authors note the data from their small pilot study need to be replicated in a larger sample before any firm conclusions can be drawn.

 

“Overall, these results suggest that the lipidation states of apolipoproteins and amyloid peptides might play a role in AD pathological processes and are influenced by APOE genotype and diet,” the study concludes.

Editorial: Food for Thought

 

In an editorial, Deborah Blacker, M.D., Sc.D., of the Massachusetts General Hospital/Harvard Medical School, Boston, writes: “The article by Hanson and colleagues makes a serious effort to understand whether dietary factors can affect the biology of Alzheimer disease (AD).”

 

“Hanson et al argue that the changes observed after their two dietary interventions may underlie some of the epidemiologic findings regarding diabetes and other cardiovascular risk factors and risk for AD. The specifics of their model may not capture the real underlying biological effect of these diets, and it is unclear whether the observed changes in the intermediate outcomes would lead to beneficial changes in oligomers or plaque burden, much less to decreased brain atrophy or improved cognition,” she continues.

 

“At some level, however, the details of the biological model are not critical; the important lesson from the study is that dietary intervention can change brain amyloid chemistry in largely consistent and apparently meaningful ways – in a short period of time. Does this change clinical practice for those advising patients who want to avoid dementia? Probably not, but it adds another small piece to the growing evidence that taking good care of your heart is probably good for your brain too,” Blacker concludes.

Parental Cultural Attitudes and Beliefs Associated with Child’s Media Viewing and Habits

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 17, 2013

Media Advisory: To contact study author Wanjiku F. M. Njoroge, M.D., call Mary Guiden at 206-987-7334 or email mary.guiden@seattlechildrens.org.

 

JAMA Pediatrics Study Highlights

Differences in parental beliefs and attitudes regarding the effects of media on early childhood development may help explain increasing racial/ethnic disparities in child media viewing/habits, according to a study by Wanjiku F. M. Njoroge, M.D., of The University of Washington, Seattle, and colleagues. (Online First)

 

A total of 596 parents of children ages 3 to 5 years completed demographic questionnaires, reported on attitudes regarding media’s risks and benefits to their children, and completed one-week media diaries in which they recorded all of the programs their children watched.

 

According to study results, children watched an average of 462.0 minutes of TV per week, with African American children watching more TV/DVDs per week than did children of other racial/ethnic backgrounds. The relationship between child race/ethnicity and average weekly media time was no longer statistically significant after controlling for socioeconomic status (parental educational attainment and reported annual family income), indicating that the observed relationship between race/ethnicity and media time was significantly confounded by socioeconomic (SES) status. Significant differences were found between parents of ethnically/racially diverse children and parents of non-Hispanic white children regarding the perceived positive effects of TV viewing, even when parental education and family income were taken into account.

 

“These findings point to an important relationship between parental attitudes/beliefs about child media use and time that could be useful for intervention work.” The study concludes, “Because of the strong relationship between SES and media exposure in our sample, future research with larger samples of children from diverse racial/ethnic backgrounds is warranted to better understand the complexities of race/ethnicity, family SES, and parental beliefs and attitudes on child media exposure.”

Study Details Age Disparities in HIV Continuum of Care

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 17, 2013

Media Advisory: To contact H. Irene Hall, Ph.D., call the NCHHSTP Media Office at 404-639-8895 or email NCHHSTPMediaTeam@cdc.gov. To contact corresponding commentary author Diane V. Havlir, M.D., call Jeff Sheehy at 415-845-1132 or email jsheehy@ari.ucsf.edu.


CHICAGO – Age disparities exist in the continuum of care for patients with the human immunodeficiency virus (HIV) with people younger than 45 years less likely to be aware of their infection or to have a suppressed viral load, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

Early diagnosis, prompt and sustained care, and antiretroviral therapy (ART) are associated with reduced morbidity, mortality and further transmission of the virus. However, of the more than 1.1 million people living with HIV, more than 200,000 are unaware they are infected, less than 50 percent of people infected receive regular care and fewer than 30 percent have a suppressed viral load, the authors write in the study background.

 

H. Irene Hall, Ph.D., of the Centers for Disease Control and Prevention, Atlanta, and colleagues used data from the National HIV Surveillance System to determine the number of people living with HIV who are aware and unaware of their infection. Researchers also calculated the percentage of people linked to care within three months of diagnosis and estimated the percentages of people who were retained in care and who were prescribed ART.

 

“Additional efforts are needed to ensure that all persons with HIV receive a diagnosis and optimal care to reduce morbidity, mortality, disparities in care and treatment, and ultimately HIV transmission,” the authors note.

 

Of the estimated more than 1.1 million persons living with HIV in 2009, nearly 81.9 percent had been diagnosed, 65.8 percent were linked to care and 36.7 percent were retained in care, 32.7 percent were prescribed ART and 25.3 percent had a suppressed viral load, according to study results.

 

Among people infected with HIV who were 13 to 24 years of age, 40.5 percent had received a diagnosis and 30.6 percent were linked to care. Lower percentages of people ages 25 to 44 were retained in care, were prescribed ART and had a suppressed viral load than were people ages 55 to 64 years of age. For example, among patients ages 25 to 34 years, 28 percent were in care compared with 46 percent among those patients ages 55 to 64 years, the results indicate.

 

Overall, 857,276 patients with HIV had not achieved viral suppression, including 74.8 percent of male, 79 percent of black, 73.9 percent of Hispanic/Latino and 70.3 percent of white patients, the results also show.

 

“Individuals, health care providers, health departments and government agencies must all work together to increase the numbers of people living with HIV who are aware of their status, linked to and retained in care, receiving treatment and adherent to treatment,” the authors conclude.

Commentary: Overcoming the HIV Obstacle Course

 

In an invited commentary, Katerina A. Christopoulos, M.D., M.P.H., and Diane V. Havlir, M.D., of the University of California, San Francisco, write: “In 2011, the HIV field was shocked to learn that only about a quarter of individuals living with HIV were successfully receiving HIV treatment.”

 

“The sobering numbers of those missing out on effective treatment because they did not know they were infected and those who knew their status but did not seek care spurred collaboration between the HIV treatment and prevention movements, two areas with different funding streams that often operated independently of one another,” they continue.

 

“Already the HIV community has mobilized to further develop and study interventions that address bottlenecks in the cascade. Achieving an AIDS-free generation will be within reach if, and only if, these efforts succeed,” they conclude.

Study Examines Hispanic Youth Exposure to Food, Beverage TV Ads

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 17, 2013

Media Advisory: To contact author Frances Fleming-Milici, Ph.D., call Megan Orciari at 203-432-8520 or email Megan.Orciari@Yale.edu.


CHICAGO – Hispanic preschoolers, children and adolescents viewed, on average about 12 foods ads per day on television in 2010, with the majority of these ads appearing on English-language TV, whereas fast-food represented a higher proportion of the food ads on Spanish-language television, according to a study published Online First by JAMA Pediatrics, a JAMA Network publication.

 

High obesity rates among young people is a public health concern in the United States and exposure to large numbers of advertisements for food products with little or no nutritional value likely contributes to the problem, according to the study background.

 

Frances Fleming-Milici, Ph.D., and colleagues at Yale University, New Haven, Conn., using a Nielsen panel of television viewing households, measured the amount of food and beverage advertising viewed by Hispanic youth on Spanish-language and English-language TV and compared it with the amount of food and beverage advertising viewed by non-Hispanic youth.

 

“Given higher rates of obesity and overweight for Hispanic youth, it is important to understand the amount and types of food advertising they view,” according to the study.

 

In 2010, Hispanic preschoolers, children and adolescents viewed 4,218, 4,373 and 4,542 total food and beverage ads on television, respectively, or 11.6 to 12.4 ads per day. Preschoolers viewed 1,038 food advertisements on Spanish-language TV, the most of any age group, according to the study.

 

Because there is somewhat less food advertising on Spanish-language television, Hispanic children and adolescents viewed 14 percent and 24 percent fewer food ads overall, respectively, compared with non-Hispanic youth. About half of the food ads viewed on Spanish-language TV promoted fast food, cereal and candy.

 

“Given the potential for greater effects from exposure to Hispanic-targeted advertising, the recent introductions of new media and marketing campaigns targeted to bilingual Hispanic youth, and food companies’ stated intentions to increase marketing to Hispanics, continued monitoring of food and beverage marketing to Hispanic youth is required,” the authors conclude.

Eating More Red Meat Associated With Increased Risk of Type-2 Diabetes

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 17, 2013

Media Advisory: To contact An Pan, Ph.D., email ephanp@nus.edu.sg. To contact commentary author William J. Evans, Ph.D., call Rachel Harrison at 919-419-5069 or email Rachel.Harrison@Duke.edu or call Sarah Avery at 919-660-1306 or email Sarah.Avery@Duke.edu


CHICAGO – Eating more red meat over time is associated with an increased risk of type-2 diabetes mellitus (T2DM) in a follow-up of three studies of about 149,000 U.S. men and women, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

Red meat consumption has been consistently related to an increased risk of T2DM, but previous studies measured red meat consumption at a baseline with limited follow-up information. However, a person’s eating behavior changes over time and measurement of consumption at a single point in time does not capture the variability of intake during follow-up, the authors note in the study background.

 

An Pan, Ph.D., of the National University of Singapore, and colleagues analyzed data from three Harvard group studies and followed up 26,357 men in the Health Professionals Follow-up Study; 48,709 women in the Nurses’ Health Study; and 74,077 women in the Nurses’ Health Study II. Diets were assessed using food frequency questionnaires.

 

During more than 1.9 million person-years of follow-up, researchers documented 7,540 incident cases of T2DM.

 

“Increasing red meat intake during a four-year interval was associated with an elevated risk of T2DM during the subsequent four years in each cohort,” according to the study.

 

The results indicate that compared with a group with no change in red meat intake, increasing red meat intake of more than 0.50 servings per day was associated with a 48 percent elevated risk in the subsequent four-year period. Reducing red meat consumption by more than 0.50 servings per day from baseline to the first four years of follow-up was associated with a 14 percent lower risk during the subsequent entire follow-up.

 

The authors note the study is observational so causality cannot be inferred.

 

“Our results confirm the robustness of the association between red meat and T2DM and add further evidence that limiting red meat consumption over time confers benefits for T2DM prevention,” the authors conclude.

Commentary: Oxygen-Carrying Proteins in Meat and Risk of Diabetes Mellitus

 

In an invited commentary, William J. Evans, Ph.D., of GlaxoSmithKline and Duke University, Durham, N.C., writes: “The article by Pan et al confirms previous observations that the consumption of so-called red meat is associated with an increased risk of type 2 diabetes mellitus (T2DM).”

 

“Perhaps a better description of the characteristics of the meat consumed with the greatest effect on risk is the saturated fatty acid (SFA) content rather than the amount of oxygen-carrying proteins,” Evans continues.

 

“A recommendation to consume less red meat may help to reduce the epidemic of T2DM. However, the overwhelming preponderance of molecular, cellular, clinical and epidemiological evidence suggests that public health messages should be directed toward the consumption of high-quality protein that is low in total and saturated fat. … These public health recommendations should include cuts of red meat that are also low in fat, along with fish, poultry and low-fat dairy products. It is not the type of protein (or meat) that is the problem: it is the type of fat,” Evans concludes.

Laparoscopic Ventral Hernia Repair Associated with Lower Cost of Care and Shorter Hospital Stay For Obese Patients

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, JUNE 12, 2013

Media Advisory: To contact study author Justin Lee, M.D., call Christopher Murphy at 617-419-4729 or email Christopher.Murphy@Steward.org.

JAMA Surgery Study Highlights


The outcomes of laparoscopic compared with open ventral hernia repair (VHR) in obese patients was examined in study by Justin Lee, M.D., of Tufts University School of Medicine, Boston, and colleagues. (Online First)

 

The retrospective group analysis included 47,661 obese patients who underwent VHR from 2008 through 2009. Main outcomes analyzed were intraoperative and postoperative complications, length of stay, and total hospital charges. Additional patient demographics, including insurance, median income, and locations, were analyzed.

 

Of the 47,661 obese patients who underwent VHR during the study period, laparoscopic VHR increased more than 4-fold, from 1,547 (6.5 percent) to 6,629 (28.0 percent). Laparoscopic VHR was associated with a lower overall complication rate (6.3 percent versus 13.7 percent), shorter median length of stay (3 versus 4 days), and lower average total hospital charges ($40,387 versus $48,513). Patients with private insurance were also more likely to undergo laparoscopic VHR, according to the study results.

 

“In the era of laparoscopy, the overall use of laparoscopic VHR in obese patients has increased significantly and appears to be safe, with a shorter stay and a lower cost of care,” the authors conclude.

Autoimmune Diseases and Infections Associated With Increased Risk of Subsequent Mood Disorder

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, JUNE 12, 2013

JAMA Psychiatry Study Highlights


Autoimmune diseases and infections appear to be risk factors for subsequent mood disorder diagnosis, according to a study by Michael E. Benros, M.D., of Aarhus University, Denmark, and colleagues.

 

A total of 91,637 people born in Demark between 1945 and 1996 were found to have visited a hospital for a mood disorder.  Researchers found a prior hospital contact because of autoimmune disease increased the risk of a subsequent mood disorder diagnosis by 45 percent. Any history of hospitalization for infection increased the risk of later mood disorders by 62 percent. Approximately one-third (32 percent) of the participants diagnosed as having a mood disorder had a previous hospital contact because of an infection, whereas 5 percent had a previous hospital contact because of an autoimmune disease, the study finds. 

 

“Autoimmune disease and the number of severe infections are independent and synergistic risk factors for mood disorders, with hospital-treated infections being the most common risk factor…these associations are compatible with the hypothesis of a general immunologic response affecting the brain in subgroups of patients with mood disorders,” the study concludes.

Hearing Loss Associated With Hospitalization, Poorer Self-Reported Health

“Hearing loss (HL) is a chronic condition that affects nearly 2 of every 3 adults aged 70 years or older in the United States. Hearing loss has broader implications for older adults, being independently associated with poorer cognitive and physical functioning. The association of HL with other health economic outcomes, such as health care use, is unstudied,” writes Dane J. Genther, M.D., of Johns Hopkins University School of Medicine, Baltimore, and colleagues, in a Research Letter. The authors investigated the association of HL with hospitalization and burden of disease in a nationally representative study of adults 70 years of age or older.

The researchers analyzed combined data from the 2005-2006 and 2009-2010 cycles of the National Health and Nutrition Examination Survey (NHANES), an ongoing epidemiological study designed to assess the health and functional status of the civilian, noninstitutionalized U.S. population. Air-conduction pure-tone audiometry was administered to all individuals aged 70 years or older, according to established NHANES protocols. Hearing was defined using World Health Organization criteria. Data on hospitalizations (during the previous 12 months) and on burden of disease (during the previous 30 days) were gathered through computer-assisted or interviewer-administered questionnaires.

The authors found that compared with individuals with normal hearing (n=529), individuals with HL (n=1,140) were more likely to have a positive history for cardiovascular risk factors, have a history of hospitalization in the past year (18.7 percent vs. 23.8 percent), and have more hospitalizations (1.27 vs. 1.52). “Fully adjusted models accounting for demographic and cardiovascular risk factors demonstrated that HL (per 25 dB) was significantly associated with any hospitalization, number of hospitalizations, more than 10 days of self-reported poor physical health, and more than 10 days of self-reported poor mental health,” the researchers write.

“Additional research is needed to investigate the basis of these observed associations and whether hearing rehabilitative therapies could help reduce hospitalizations and improve self-reported health in older adults with HL.”

 Encouraging Patients to Ask Questions – How to Overcome ‘White-Coat Silence’

Timothy J. Judson, M.P.H., of Weill Cornell Medical College, New York, and colleagues examine the barriers that prevent patients and physicians from meaningful question-and-answer exchanges and offer suggestions for how these barriers may be overcome.

“In most industries, consumer experience is paramount. Encouraging patients to ask questions is a start but needs to be part of a more fundamental re-engineering of health care toward a patient-centered experience in which white coats provoke more open dialogue and less apprehensive silence.”

Enhancing Patient-Centered Communication and Collaboration by Using the Electronic Health Record in the Examination Room

Amina White, M.D., and Marion Danis, M.D., of the National Institutes of Health, Bethesda, Md., write that “the presence of a computer in the examination room and the pressure to document the visit in the electronic health record (EHR) are often perceived as adversely affecting the patient-physician interaction.” In this Viewpoint, the authors discuss how the EHR can “instead have a positive effect on this interaction and promote patient activation during the course of the outpatient visit.”

“Using the EHR as a relational tool is a strategy for improving individual and population-based health outcomes, for various studies have shown that interventions aimed at increasing patient activation have led to significant improvements in the management of chronic disease, mental illness, and other health-related behaviors or conditions. The health care community may find the EHR to be an untapped means of encouraging patient-physician collaboration and for enhancing patient activation during the clinic visit. Future empirical studies are needed to explore the potential benefits of this expanded use of the EHR on quantitative measures of patient activation.”

 Editorial: Talking to Patients in the 21st Century

In an editorial, Abigail Zuger, M.D., of St. Luke’s-Roosevelt Hospital Center, New York, comments on the Viewpoints in this issue of JAMA that “address some of the changes in physicians’ speaking and writing habits that will be necessary to accommodate new models of practice.”

“So what communication skills will be required of the fully evolved 21st century physician? The physician will, of course, be fluent in standard clinical language, including ordinary medical terminology and the delicate phrases of care and compassion. The physician will be adept at translating medical jargon into comprehensible lay terms, knowing how to defuse words, such as obese or psychotic, that might cause alarm or hurt feelings. The physician will know how to explain statistical concepts both accurately and intelligibly with the patience and fortitude to answer patients’ questions about all things evidence-based, even the physician’s own competence.”

“The physician will know the highly technical vocabulary of relevant research agendas well enough to encourage patients to get involved. The physician will also keep up with popular culture, tracking popular direct-to-patient communications and incorporating them into the clinical dialogue. In addition, and most importantly, the physician will have virtuoso data entry and retrieval skills, with an ability to talk, think, listen, and type at the same time rivaling that of court reporters, simultaneous interpreters, and journalists on deadline. The physician will do all of this efficiently and effectively through dozens of clinical encounters a day, each one couched in a slightly different vernacular.”

Certain Inflammatory Biomarkers Associated With Increased Risk of COPD Exacerbations

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 11, 2013

Media Advisory: To contact corresponding author Borge G. Nordestgaard, D.M.Sc., email Boerge.Nordestgaard@regionh.dk. To contact editorial co-author Sanjay Sethi, M.D., call Ellen Goldbaum at 716-645-4605 or email goldbaum@buffalo.edu.


CHICAGO – Simultaneously elevated levels of the biomarkers C-reactive protein, fibrinogen and leukocyte count in individuals with chronic obstructive pulmonary disease (COPD) were associated with increased risk of having exacerbations, even in those with milder COPD and in those without previous exacerbations, according to a study in the June 12 issue of JAMA.

“Exacerbations of respiratory symptoms in COPD are of major importance because of their profound and long-lasting adverse effects on patients. Frequent episodes accelerate loss of lung function, affect the quality of life of the patients, and are associated with poor survival,” according to background information in the article. Some patients with COPD have evidence of low-grade systemic inflammation with increased levels of certain inflammatory biomarkers during stable conditions, and previous studies have found that elevated levels of inflammatory biomarkers like C-reactive protein (CRP), fibrinogen, and leukocytes during stable COPD are associated with poor outcomes.

Mette Thomsen, M.D., of Herlev Hospital, Copenhagen University Hospital, Herlev, Denmark, and colleagues tested the hypothesis that elevated levels of inflammatory biomarkers in individuals with stable COPD are associated with an increased risk of having exacerbations. The prospective study examined 61,650 participants with spirometry measurements from the Copenhagen City Heart Study (2001-2003) and the Copenhagen General Population Study (2003-2008). Of these, 6,574 had COPD. Baseline levels of CRP, fibrinogen and leukocyte count were measured in participants at a time when they were not experiencing symptoms of exacerbations. Exacerbations were recorded and defined as short-course treatment with oral corticosteroids alone or in combination with an antibiotic or as a hospital admission due to COPD.

During a median (midpoint) 4 years of follow-up time, 3,083 exacerbations were recorded (average, 0.5/participant). The researchers found that the risk of having frequent exacerbations was increased approximately 4-fold in the first year of follow-up and 3-fold using maximum follow-up time in individuals with 3 high inflammatory biomarkers compared with individuals who had no elevated biomarkers. “Importantly, relative risk estimates were consistent even in those with milder COPD and in those with no history of frequent exacerbations, suggesting that these biomarkers provide additional information to the latest Global Initiative for Chronic Obstructive Lung Disease [GOLD] 2011 grading.”

The highest 5-year absolute risks of having frequent exacerbations in those with 3 high biomarkers (vs. no high biomarkers) were 62 percent (vs. 24 percent) for those with GOLD grades C-D (n=558), 98 percent (vs. 64 percent) in those with a history of frequent exacerbations (n=127), and 52 percent (vs. 15 percent) for those with GOLD grades 3-4 (n=465).

“… our study provides novel information that may lead to a simpler assessment using measurements of inflammatory biomarkers in individuals with stable COPD to further stratify preventive therapies based on absolute risk of frequent exacerbations. The potential benefits of such stratification should be tested in future clinical trials that could include drugs of particular current interest, such as macrolides or statins,” the authors write.

Editorial: Systemic Inflammation in Predicting COPD Exacerbations

“The study by Thomsen et al adds to the growing interest in systemic inflammation in COPD and its negative consequences and raises several interesting biological questions,” write M. Jeffery Mador, M.D., and Sanjay Sethi, M.D., of the University at Buffalo, State University of New York, Buffalo, in an accompanying editorial.

“What is the origin of systemic inflammation in COPD, as it persists in ex-smokers and therefore cannot be simply attributed to smoke exposure? Does systemic inflammation influence lungs’ innate defenses against microbial pathogens, or is it a reflection of impaired lung defense and consequent immune-inflammatory dysregulation in the lung?”

“There is tremendous enthusiasm and effort to improve current therapies and develop new therapies for exacerbation reduction in COPD. Appropriate development and use of these interventions will need careful phenotyping of patients with COPD, using clinical and biomarker measures. Thomsen et al have shown that biomarkers may hold promise for identifying high-risk patients and that assessing combinations of biomarkers, rather than a single measurement, may be needed to improve risk stratification.”

Maternal Overweight and Obesity During Pregnancy Associated With Increased Risk of Preterm Delivery

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 11, 2013

Media Advisory: To contact Sven Cnattingius, M.D., Ph.D., email sven.cnattingius@ki.se.


CHICAGO – In a study that included more than 1.5 million deliveries in Sweden, maternal overweight and obesity during pregnancy were associated with increased risk for preterm delivery, with the highest risks observed for extremely preterm deliveries, according to a study in the June 12 issue of JAMA.

“Maternal overweight and obesity has, due to the high prevalence and associated risks, replaced smoking as the most important preventable risk factor for adverse pregnancy outcomes in many countries. Preterm birth, defined as a delivery of a liveborn infant before 37 gestational weeks, is the leading cause of infant mortality, neonatal morbidity, and long-term disability among non-malformed infants, and these risks increase with decreasing gestational age,” according to background information in the article.

Sven Cnattingius, M.D., Ph.D., of the Karolinska Institutet, Stockholm, Sweden, and colleagues conducted a study to examine the associations between early pregnancy body mass index (BMI) and risk of preterm delivery by gestational age and by precursors of preterm delivery. The study included women with live single births in Sweden from 1992 through 2010. Maternal and pregnancy characteristics were obtained from the nationwide Swedish Medical Birth Register. The primary measured outcomes for the study were the risks of preterm deliveries (extremely, 22-27 weeks; very, 28-31 weeks; and moderately, 32-36 weeks). These outcomes were further characterized as spontaneous (related to preterm contractions or preterm premature rupture of membranes) and medically indicated preterm delivery (cesarean delivery before onset of labor or induced onset of labor).

BMI was calculated from information on height and weight at the first prenatal visit. BMI was used to characterize the women as underweight (BMI<18.5), normal (18.5-<25), overweight (25-<30), obese grade 1 (30-<35), obese grade 2 (35-<40), or obese grade 3 (≥40).

Among 1,599,551 deliveries with information on early pregnancy BMI, 3,082 were extremely preterm, 6,893 were very preterm, and 67,059 were moderately preterm. The researchers found that risks of extremely, very, and moderately preterm deliveries increased with BMI and the overweight and obesity-related risks were highest for extremely preterm delivery. Compared with normal-weight women, women with grade 2 and 3 obesity (BMI≥35) had 0.2 percent to 0.3 percent higher rates of extremely preterm delivery and 0.3 percent to 0.4 percent higher rates of very preterm delivery.

“Risk of spontaneous extremely preterm delivery increased with BMI among obese women (BMI≥30). Risks of medically indicated preterm deliveries increased with BMI among overweight and obese women,” the authors write.

“These results can be generalized to other populations with similar or higher rates of maternal obesity or preterm delivery in as much as the underlying pathways linking maternal obesity and preterm delivery are common across populations. In the United States, where preterm delivery rates are twice as high as in Sweden, the majority of women are either overweight (26.0 percent) or obese (27.4 percent) in early pregnancy, and severe obesity (BMI≥35) is much more common than in Sweden. In 2008, extremely (<28 weeks) preterm births accounted for 0.60 percent of all live single births and 25 percent of all U.S. infant deaths among singletons, and extremely preterm birth is also the leading cause of long-term disability.”

“Considering the high morbidity and mortality among extremely preterm infants, even small absolute differences in risks will have consequences for infant health and survival. Even though the obesity epidemic in the United States appears to have leveled off, there is a sizeable group of women entering pregnancy with very high BMI. Our results need to be confirmed in other populations given their potential public health relevance. Identifying the pathways through which maternal obesity influences offspring health is also needed to provide critical information to specifically target the women at highest risk of preterm delivery,” the researchers conclude.

Study Finds Very High Prevalence of Chronic Health Conditions Among Adult Survivors of Childhood Cancer

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 11, 2013

Media Advisory: To contact Melissa M. Hudson, M.D., call Summer Freeman at 901-595-3061 or email summer.freeman@stjude.org.


CHICAGO – In an analysis that included more than 1,700 adult survivors of childhood cancer, researchers found a very high percentage of survivors with 1 or more chronic health conditions, with an estimated cumulative prevalence of any chronic health condition of 95 percent at age 45 years, according to a study in the June 12 issue of JAMA.

“Curative therapy for pediatric malignancies has produced a growing population of adults formerly treated for childhood cancer who are at risk for health problems that appear to increase with aging. The prevalence of cancer-related toxic effects that are systematically ascertained through formal clinical assessments has not been well studied. Ongoing clinical evaluation of well-characterized cohorts is important to advance knowledge about the influence of aging on cancer-related morbidity and mortality and to guide the development of health screening recommendations and health-preserving interventions,” according to background information in the article.

Melissa M. Hudson, M.D., of St. Jude Children’s Research Hospital and the University of Tennessee College of Medicine, Memphis, and colleagues conducted a study to determine, through systematic comprehensive medical assessment, the general health status of long-term survivors of childhood cancer and the prevalence of treatment complications following predisposing cancer treatment-related exposures. The presence of health outcomes was ascertained using systematic exposure-based medical assessments among 1,713 adult (median [midpoint] age, 32 years) survivors of childhood cancer (median time from diagnosis, 25 years) enrolled in the St. Jude Lifetime Cohort Study since October 1, 2007, and undergoing follow-up through October 31, 2012. The participants were diagnosed and treated between 1962 and 2001. The primary measured outcomes were the age-specific cumulative prevalence of adverse outcomes by organ system.

The researchers found that impaired pulmonary, auditory, cardiac, endocrine, and nervous system function were most prevalent (detected in 20 percent or more of participants at risk). The crude prevalence of adverse health outcomes was highest for pulmonary (abnormal pulmonary function, 65.2 percent), auditory (hearing loss, 62.1 percent) endocrine or reproductive (any endocrine condition, such as hypothalamic-pituitary axis disorders and male germ cell dysfunction, 62.0 percent), cardiac (any cardiac condition, such as heart valve disorders, 56.4 percent), and neurocognitive (neurocognitive impairment, 48.0 percent) function.

“Among survivors at risk for adverse outcomes following specific cancer treatment modalities, the estimated cumulative prevalence at age 50 years was 21.6 percent for cardiomyopathy, 83.5 percent for heart valve disorder, 81.3 percent for pulmonary dysfunction, 76.8 percent for pituitary dysfunction, 86.5 percent for hearing loss, 31.9 percent for primary ovarian failure, 31.1 percent for Leydig cell failure, and 40.9 percent for breast cancer,” the authors write.

Abnormalities involving hepatic, skeletal, renal, and hematopoietic function were less common (less than 20 percent).

“In this clinically evaluated cohort, 98.2 percent of participants had a chronic health condition,” the researchers note. “The overall cumulative prevalence of a chronic condition was estimated to be 95.5 percent by age 45 years and 93.5 percent 35 years after cancer diagnosis.” At age 45 years, the estimated cumulative prevalence was 80.5 percent for a serious/disabling or life-threatening chronic condition.

“In summary, this study provides global and age-specific estimates of clinically ascertained morbidity in multiple organ systems in a large systematically evaluated cohort of long-term survivors of childhood cancer. The percentage of survivors with 1 or more chronic health conditions prevalent in a young adult population was extraordinarily high. These data underscore the need for clinically focused monitoring, both for conditions that have significant morbidity if not detected and treated early, such as second malignancies and heart disease, and also for those that if remediated can improve quality of life, such as hearing loss and vision deficits.”

Intervention Results in Improved Adherence to Prescribing Guidelines for Bacterial Respiratory Tract Infections of Children

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 11, 2013

Media Advisory: To contact Jeffrey S. Gerber, M.D., Ph.D., call Rachel Salis-Silverman at 267-426-6063 or email Salis@email.chop.edu. To contact editorial author Jonathan A. Finkelstein, M.D., M.P.H., call Meghan Weber at 617-919-3656 or email Meghan.Weber@childrens.harvard.edu.


CHICAGO – An intervention consisting of clinician education coupled with personalized audit and feedback about antibiotic prescribing improved adherence to prescribing guidelines for common pediatric bacterial acute respiratory tract infections, although the intervention did not affect antibiotic prescribing for viral infections, according to a study in the June 12 issue of JAMA.

“Antibiotics are the most common prescription drugs given to children. Although hospitalized children frequently receive antibiotics, the vast majority of antibiotic use occurs in the outpatient setting, roughly 75 percent of which is for acute respiratory tract infections (ARTIs). Unnecessary prescribing for viral ARTIs is well documented and has been declining. However, inappropriate prescribing also occurs for bacterial ARTIs, particularly when broad-spectrum antibiotics are used to treat infections for which narrow-spectrum antibiotics are indicated and recommended,” according to background information in the article. “Antimicrobial stewardship programs have been effective for inpatients, often through prescribing audit and feedback. However, most antimicrobial use occurs in outpatients with acute respiratory tract infections.

Jeffrey S. Gerber, M.D., Ph.D., of The Children’s Hospital of Philadelphia, and colleagues conducted a study to evaluate the effect of an antimicrobial stewardship intervention on antibiotic prescribing for pediatric outpatients. The randomized trial of outpatient antimicrobial stewardship compared prescribing between intervention and control practices using a common electronic health record. After excluding children with chronic medical conditions, antibiotic allergies, and prior antibiotic use, the researchers estimated prescribing rates for targeted ARTIs standardized for age, sex, race, and insurance from 20 months before the intervention to 12 months afterward (October 2008-June 2011). The study included a network of 18 pediatric primary care practices in Pennsylvania and New Jersey (162 clinicians). Overall, there were 1,291,824 office visits by 185,212 unique patients.

The intervention consisted of one 1-hour on-site clinician education session followed by 1 year of personalized, quarterly audit and feedback of prescribing for bacterial and viral ARTIs or usual practice. The researchers measured rates of broad-spectrum (off-guideline) antibiotic prescribing for bacterial ARTIs and antibiotics for viral ARTIs for 1 year after the intervention.

The authors found that among children who were prescribed antibiotics for any indication, the overall proportion of antibiotic prescriptions that were broad-spectrum decreased from 26.8 percent to 14.3 percent in the intervention group and from 28.4 percent to 22.6 percent in control practices (difference of differences [DOD], 6.7 percent) during the 12-months following initiation of education/audit and feedback.

“When stratifying by the individual bacterial ARTIs targeted by the intervention, broad-spectrum (off-guideline) antibiotic prescribing for pneumonia decreased from 15.7 percent to 4.2 percent in the intervention group and from 17.1 percent to 16.3 percent in the control group (DOD, 10.7 percent). Broad-spectrum prescribing for acute sinusitis decreased from 38.9 percent to 18.8 percent in the intervention group and from 40.0 percent to 33.9 percent in the control practices (DOD, 14.0 percent). Broad-spectrum prescribing for streptococcal pharyngitis started and remained low for both the intervention group (from 4.4 percent to 3.4 percent) and the control group (from 5.6 percent to 3.5 percent) (DOD, -1.1 percent),” they write.

In addition, the baseline rate of any antibiotic prescribing for viral infections was low and did not change significantly after the intervention in either the intervention group (from 7.9 percent to 7.7 percent) or the control group (from 6.4 percent to 4.5 percent) (DOD, -1.7 percent).

“This intervention nearly halved prescribing of broad-spectrum antibiotics to children during acute primary care encounters and decreased use of off-guideline antibiotics for children with pneumonia by 75 percent by 1 year after the intervention,” the researchers note.

“Our findings suggest that extending antimicrobial stewardship to the ambulatory setting, where such programs have generally not been implemented, may have important health benefits.”

“This targeted application of antimicrobial stewardship principles to the ambulatory setting has the potential to affect the most common indications for antibiotic use. Future studies should examine the key drivers of these effects on antibiotic prescribing and the generalizability of findings to other health systems and measure the sustainability and clinical outcomes associated with differential prescribing patterns,” the authors conclude.

Editorial: Putting Antibiotic Prescribing for Children Into Context

“Gerber et al and the participating practices and clinicians have accomplished meaningful improvement in antibiotic prescribing for ARTIs in their pediatric patients,” writes Jonathan A. Finkelstein, M.D., M.P.H., of Boston Children’s Hospital and Harvard Medical School, Boston, in an accompanying editorial.

“However, broad-spectrum antibiotic overuse continues in humans across age groups and conditions, as well as in agricultural use and other factors that drive emerging resistance. The good news is that a range of effective techniques for promoting judicious prescribing in ambulatory care have been developed and tested; it is also apparent that the influence and benefit of any of these interventions will vary greatly across settings. Tailoring strategies to contextual factors and adapting them further during implementation may well be more effective than merely rolling out the approach with the greatest average effect in the average practice.”

Study Examines Cancer Risk from Pediatric Radiation Exposure From CT Scans

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 10, 2013

Media Advisory: To contact Diana L. Miglioretti, Ph.D., call Phyllis Brown at 916-734-9023 or email Phyllis.Brown@ucdmc.ucdavis.edu. To contact editorial author Rita Redberg, M.D., call 312-464-5262 or email mediarelations@jamanetwork.org.


CHICAGO – According to a study of seven U.S. healthcare systems, the use of computed tomography (CT) scans of the head, abdomen/pelvis, chest or spine, in children younger than age 14 more than doubled from 1996 to 2005, and this associated radiation is projected to potentially increase the risk of radiation-induced cancer in these children in the future, according to a study published Online First by JAMA Pediatrics, a JAMA Network publication.

 

The use of CT in pediatrics has increased over the last two decades. The ionizing radiation doses delivered by the tests are higher than convention radiography and are in ranges that have been linked to an increased risk of cancer. Children are more sensitive to radiation-induced carcinogenesis and have many years of life left for cancer to develop, the authors write in the study background.

 

“The increased use of CT in pediatrics, combined with the wide variability in radiation doses, has resulted in many children receiving a high-dose examination,” the study notes.

 

Diana L. Miglioretti, Ph.D., of the Group Health Research Institute and University of California, Davis, and colleagues quantified trends in the use of CT in pediatrics plus the associated radiation exposure and estimated potential cancer risk using data from seven U.S. health care systems.

 

The authors note the use of CT doubled for children younger than 5 years old and tripled for children 5 to 14 years of age between 1996 and 2005 before remaining stable between 2006 and 2007 and then beginning to decline.

 

The projected lifetime attributable risks of solid cancer were higher for younger patients and girls than for older patients and boy. The risks were also higher for patients who underwent CT scans of the abdomen/pelvis or spine than for patients who underwent other types of CT scans, according to the results.

 

The estimates also suggest that for girls, a radiation-induced solid cancer is projected to potentially result from every 300 to 390 abdomen/pelvis scans, 330 to 480 chest scans, and 270 to 800 spine scans, depending on age. The potential risk of leukemia was highest from head scans for children younger than 5 years of age at a rate of 1.9 cases per 10,000CT scans, the results show.

 

The authors estimate that 4,870 future cancers could be caused by the 4 million pediatric CT scans performed each year. Based on their calculations, the authors also suggest that reducing the highest 25 percent of doses to the median (midpoint) may prevent 43 percent of these cancers, the authors suggest.

 

“Thus, more research is urgently needed to determine when CT in pediatrics can lead to improved health outcomes and whether other imaging methods (or no imaging) could be as effective. For now, it is important for both the referring physician and the radiologist to consider whether the risks of CT exceed the diagnostic value it provides over other tests, based on current evidence,” the study concludes.

Editorial: The Harm in Looking

In a related editorial, Alan R. Schroeder, M.D., of the Santa Clara Valley Medical Center, San Jose, and Rita F. Redberg, M.D., editor of JAMA Internal Medicine and of the University of California, San Francisco, write: “Thus, minimizing radiation exposure by eliminating unnecessary scans and by using the minimal dose necessary to achieve a satisfactory image for necessary scans is a high priority.”

 

“But we can still do more to decrease the use of unnecessary scans (for which the benefit does not outweigh the risk) and to decrease the level of radiation exposure from necessary scans. This will require a shift in our culture to become more tolerant of clinical diagnoses without confirmatory imaging, more accepting of ‘watch and wait’ approaches and less accepting of the ‘another test can’t hurt’ mentality,” they continue.

 

“Uncertainty can be unsettling, but it is a small price to pay for protecting ourselves and our children from thousands of preventable cancers,” they conclude.

Low Diastolic Blood Pressure May Be Associated With Brain Atrophy

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 10, 2013

Media Advisory: To contact corresponding author Mirjam I. Geerlings, Ph.D., email m.geerlings@umcutrecht.nl.


CHICAGO – Low baseline diastolic blood pressure (DBP) appears to be associated with brain atrophy in patients with arterial disease, whenever declining levels of blood pressure (BP) over time among patients who had a higher baseline BP were associated with less progression of atrophy, according to a report published Online First by JAMA Neurology, a JAMA Network publication.

 

“Studies have shown that both high and low blood pressure (BP) may play a role in the etiology of brain atrophy. High BP in midlife has been associated with more brain atrophy later in life, whereas studies in older populations have shown a relation between low BP and more brain atrophy. Yet, prospective evidence is limited, and the relation remains unclear in patients with manifest arterial disease,” according to the study.

 

Hadassa M. Jochemsen, M.D., of University Medical Center Utrecht, the Netherlands, and colleagues examined the association of baseline BP and change in BP over time with the progression of brain atrophy in 663 patients (average age 57 years; 81 percent male). The patients had coronary artery disease, cerebrovascular disease, peripheral artery disease or abdominal aortic aneurysm.

 

According to the results, patients with lower baseline DBP or mean arterial pressure (MAP) had more progression of subcortical (the area beneath the cortex of the brain) atrophy. In patients with higher BP (DBP, MAP or systolic BP), those with declining BP levels over time had less progression of subcortical atrophy compared with those with rising BP levels.

 

“This could imply that BP lowering is beneficial in patients with higher BP levels, but one should be cautious with further BP lowering in patients who already have low BP,” the study authors conclude.

Policies by School Districts or States Associated with Reduced Availability of Foods and Beverages High in Fats, Sugars, or Sodium Sold Outside the School Meal Program

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 10, 2013

Media Advisory: To contact study author Jamie F. Chriqui, Ph.D., M.H.S., call Sherry McGinnis Gonzalez at 312-996-8277 or email smcginn@uic.edu.

JAMA Pediatrics Study Highlights


The association between district and state policies or legal requirements regarding competitive food and beverages (food and beverages sold outside the school meal program) and public elementary school availability of foods and beverages high in fats, sugars, or sodium was examined in a study Jamie F. Chriqui, Ph.D., M.H.S., and colleagues at the University of Illinois at Chicago. (Online First)

 

Survey respondents at 1,814 elementary schools (1,485 unique) in 957 districts in 45 states (food analysis) and 1,830 elementary schools (1,497 unique) in 962 districts and 45 states (beverage analysis) participated in the study during the school years 2008-2009 and 2010-2011.

 

According to the study results, sweets were 11.2 percent less available (32.3 percent versus 43.5 percent) when both the district and state limited sugar content, respectively. Regular-fat baked goods were less available when the state law limited fat content. Regular-fat ice cream was less available when any policy limited competitive food fat content. Sugar-sweetened beverages were 9.5 percent less available when prohibited by district policy (3.6 percent versus 13.1 percent). Higher-fat milks (2 percent or whole milk)  were less available when prohibited by district policy or state law.

 

“Both district and state policies and/or laws have the potential to reduce in-school availability of high-sugar, high-fat foods and beverages. Given the need to reduce empty calories in children’s diets, governmental policies at all levels may be an effective tool,” the study concludes.

Review Article Suggests Early Intervention Needed to Reduce Lifelong Effects of Emotional, Behavioral and Developmental Features Associated with Childhood Neglect and Emotional Abuse

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 10, 2013

Media Advisory: To contact study author Aideen Mary Naughton, M.B., B.Ch., B.A.O., D.C.H., email aideen.naughton2@wales.nhs.uk.

JAMA Pediatrics Study Highlights


Preschool children who have been neglected or emotionally abused exhibit a range of emotional and behavioral difficulties and adverse mother-child interactions that indicate these children require prompt evaluation and interventions, according to a systematic review by Aideen Mary Naughton, M.B., B.Ch., B.A.O., D.C.H., F.R.C.P.C.H., of Public Health Wales, Pontypool, England, and colleagues. (Online First)

 

A total of 42 studies of children age 0 to 6 years with confirmed neglect or emotional abuse who had emotional, behavioral, and developmental features recorded or for whom the carer-child interaction was documented were analyzed.

 

Key features in the child included aggression, withdrawal or passivity, developmental delay, poor peer interaction, and transition from ambivalent to avoidant insecure attachment pattern and from passive to increasingly aggressive behavior and negative self-representation. Emotional knowledge, cognitive function, and language deteriorate without intervention. Poor sensitivity, hospitality, criticism, or disinterest characterize maternal-child interactions.

 

“Lifelong consequences include physical and mental health problems; impairments in language, social, and communication skills; and severe effects on brain development and hormonal functioning.” The study concludes, “early intervention has the potential to change children’s lives.”

Replacing Carbohydrates, Animal Fat With Vegetable Fat May Reduce Risk of Death in Men With Prostate Cancer

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 10, 2013

Media Advisory: To contact Erin L. Richman, Sc.D., call Elizabeth Fernandez at 415-514-1592 or email Elizabeth.Fernandez@ucsf.edu. To contact commentary author Stephen J. Freedland, M.D., call Rachel Bloch Harrison at 919-419-5069 or email Rachel.Harrison@Duke.edu or call Sarah Avery at 919-660-1306 or email Sarah.Avery@Duke.edu.


CHICAGO – Replacing carbohydrates and animal fat with vegetable fat may be associated with a lower risk of death in men with nonmetastatic prostate cancer, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

“Nearly 2.5 million men currently live with prostate cancer in the United States, yet little is known about the association between diet after diagnosis and prostate cancer progression and overall mortality,” according to the study background.

 

Erin L. Richman, Sc.D., of the University of California, San Francisco, and colleagues examined fat intake after a diagnosis of prostate cancer in relation to lethal prostate cancer and all-cause mortality. The study included 4,577 men diagnosed with nonmetastatic prostate cancer between 1986 and 2010 who were enrolled in the Health Professionals Follow-up Study.

 

Researchers noted 315 lethal prostate cancer events and 1,064 deaths during a median (midpoint) follow-up of 8.4 years. Replacing 10 percent of calories from carbohydrates with vegetable fat was associated with a 29 percent lower risk of lethal prostate cancer and a 26 percent lower risk of death from all-cause mortality, according to the study results.

 

“In this prospective analysis, vegetable fat intake after diagnosis was associated with a lower risk of lethal prostate cancer and all-cause mortality,” the authors comment. The authors note oils and nuts were among the top sources of vegetable fats in the study population.

 

Crude rates of lethal prostate cancer (per 1,000 person-years) comparing the highest and lowest quintiles of fat intake were: 7.6 vs. 7.3 for saturated; 6.4 vs. 7.2 for monounsaturated; 5.8 vs. 8.2 for polyunsaturated; 8.7 vs. 6.1 for trans; 8.3 vs. 5.7 for animal; and 4.7 vs. 8.7 for vegetable fat. For all-cause mortality, crude death rates (per 1,000 person-years) comparing the highest and lowest quintiles of fat intake were: 28.4 vs. 21.4 for saturated; 20.0 vs. 23.7 for monounsaturated; 17.1 vs. 29.4 for polyunsaturated; 32.4 vs. 17.1 for trans; 32.0 vs. 17.2 for animal; and 15.4 vs. 32.7 for vegetable fat, according to the study results.

 

“Overall, our findings support counseling men with prostate cancer to follow a heart-healthy diet in which carbohydrate calories are replaced with unsaturated oils and nuts to reduce the risk of all-cause mortality. … The potential benefit of vegetable fat consumption for prostate cancer-specific outcomes merits further research,” the authors conclude.

Commentary: Dietary Fat, Reduced Prostate Cancer Mortality

In an invited commentary, Stephen J. Freedland, M.D., of the Duke University Medical Center, Durham, N.C., writes: “Using data from food frequency questionnaires completed every four years during follow-up, they found that men who consumed more vegetable fat had a lower risk of prostate cancer death.”

 

“Thus, in the absence of randomized trial data, it is impossible to use these data as ‘proof’ that vegetable intake lowers prostate cancer risk, and the authors have carefully avoided such statements,” Freedland continues.

 

“When counseling patients, I remind them that obesity is the only known modifiable risk factor linked with prostate cancer mortality to date. Thus, avoiding obesity is essential. Exactly how this should be done remains unclear, although the data by Richman et al suggest that substituting healthy foods (i.e. vegetable fats) for unhealthy foods (i.e. carbohydrates) may have a benefit. Determining whether this benefit is due to reduced consumption of carbohydrates or greater intake of vegetables will require future prospective randomized trials,” Freedland concludes.

Study Suggests Association Between Hypoglycemia, Dementia in Older Adults With Diabetes

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 10, 2013

CHICAGO – A study of older adults with diabetes mellitus (DM) suggests a bidirectional association between hypoglycemic (low blood glucose) events and dementia, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

There is a growing body of evidence that DM may increase the risk for developing cognitive impairment, including Alzheimer disease and vascular dementia, and there is research interest in whether DM treatment can prevent cognitive decline. When blood glucose declines to low levels, cognitive function is impaired and severe hypoglycemia may cause neuronal damage. Previous research on the potential association between hypoglycemia and cognitive impairment has produced conflicting results, the authors write in the study background.

 

Kristine Yaffe, M.D., of the University of California, San Francisco, and colleagues studied 783 older adults with DM (average age 74 years). During a 12-year follow-up, 61 patients (7.8 percent) had a reported hypoglycemic event and 148 (18.9 percent) developed dementia.

 

“Hypoglycemia commonly occurs in patients with diabetes mellitus (DM) and may negatively influence cognitive performance. Cognitive impairment in turn can compromise DM management and lead to hypoglycemia,” according to the study.

 

Patients who experienced a hypoglycemic event had a two-fold increased risk for developing dementia compared with those who did not have a hypoglycemic event (34.4 percent vs. 17.6 percent). Older adults with DM who developed dementia had a greater risk for having a subsequent hypoglycemic event compared with patients who did not develop dementia (14.2 percent vs. 6.3 percent), according to the study results.

 

“Among older adults with DM who were without evidence of cognitive impairment at study baseline, we found that clinically significant hypoglycemia was associated with a two-fold increased risk for developing dementia … Similarly, participants with dementia were more likely to experience a severe hypoglycemic event,” the authors conclude. “The association remained even after adjustment for age, sex, educational level, race/ethnicity, comorbidities and other covariates. These results provide evidence for a reciprocal association between hypoglycemia and dementia among older adults with DM.”

Commentary: Glucose Control in Older Adults with Diabetes – More Harm Than Good?

In an invited commentary, Kasia J. Lipska, M.D., M.H.S. of the Yale University School of Medicine, New Haven, Conn., and Victor M. Montori, M.D., of the Mayo Clinic, Rochester, Minn., write: “Hypoglycemia is a major adverse consequence of glucose-lowering therapy in patients with type 2 diabetes mellitus (DM). … Older patients are at higher risk of hypoglycemia. Aging-related changes in renal function and drug clearance may contribute to this vulnerability.”

 

“Efforts to mitigate the risk of hypoglycemia are clearly warranted to improve quality of life and potentially prevent the associated adverse events,” they continue.

 

“Hypoglycemia in the course of type 2 DM treatment is both common and associated with poor outcomes. Therefore, decisions about the intensity and type of antihyperglycemic therapy must take into account the harms of hypoglycemia. Involving patients in these treatment decisions may favorably shift the current glucose-centric paradigm to a more holistic patient-centered one,” they conclude.

Postoperative Patient Care Program Associated With Reduction of Common Postoperative Complications

 

A study by Michael R. Cassidy, M.D., and colleagues at the Boston University Medical Center, suggests that I COUGH, a standardized postoperative care program emphasizing patient education, early mobilization, and pulmonary interventions, is associated with reduced risk of postoperative pneumonia and unplanned intubation. (Online First)

 

Researchers conducted a study of all patients who underwent general or vascular surgery at their institution during a 1-year period and compared the National Surgical Quality Improvement Program (NSQIP) risk-adjusted pulmonary outcomes before and after implementing I COUGH.

 

Before implementation of I COUGH, incidence of postoperative pneumonia was 2.6 percent, but decreased to 1.6 percent after implementation. The incidence of unplanned intubations was 2.0 percent before I COUGH and 1.2 percent after I COUGH.

 

“We are eager to monitor our outcomes over a longer period, and we are stimulated by the possibility that postoperative complications may be diminished by adherence to simple, inexpensive, easily performed patient care strategies,” the authors conclude.

JAMA Psychiatry Study Highlights

 

Ultra High-Risk Patients With Schizophrenia at Long-Term Risk for Psychotic Disorder

 

Ultra high-risk (UHR) patients with schizophrenia appear to be at long-term risk for psychotic disorder, with the highest risk during the first two years after entry to a specialist clinic according to a study by Barnaby Nelson, Ph.D., of the University of Melbourne, Australia.

 

The study included 416 UHR patients in a follow-up of a group of UHR patients who were recruited to participate in research studies between 1993 and 2006. Researchers assessed the transition to psychotic disorder in UHR patients up to 15 years after study entry.

 

Study results indicate that 114 of the 416 patients were known to have developed a psychotic disorder during the follow-up time (2.4-14.9 years after presentation). While the highest risk was within the first two years, individuals continued to be at risk up to 10 years after initial referral.

 

“Services should aim to follow up patients for at least this period, with the possibility to return for care after this time. Individuals with a long duration of symptoms and poor functioning at the time of referral may need closer monitoring,” the study concludes.

Musculoskeletal Conditions, Injuries May Be Associated with Statin Use

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 3, 2013

Media Advisory: To contact Ishak Mansi, M.D., call Penny Kerby at 214-857-1155 or email Penny.Kerby@va.gove.


CHICAGO – Using cholesterol-lowering statins may be associated with musculoskeletal conditions, arthropathies (joint diseases) and injuries, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

While statins effectively lower cardiovascular illnesses and death, the full spectrum of statin musculoskeletal adverse events (AEs) is unknown. Statin-associated musculoskeletal AEs include a wide variety of clinical presentations, including muscle weakness, muscle cramps and tendinous (tendon) diseases, the authors write in the study background.

 

Ishak Mansi, M.D., of the VA North Texas Health Care System, Dallas, and colleagues utilized data from a military health care system to determine whether statins were associated with musculoskeletal conditions based on statin use during the 2005 fiscal year. Patients were divided into two groups: statin users for at least 90 days and nonusers. A total of 46,249 patients met the study criteria and of those, researchers propensity score-matched (a statistical approach that mathematically matches the characteristics of patients in two or more groups) 6,967 statin users with 6,967 nonusers.

 

“Musculoskeletal conditions, arthropathies, injuries and pain are more common among statin users than among similar nonusers. The full spectrum of statins’ musculoskeletal adverse events may not be fully explored, and further studies are warranted, especially in physically active individuals,” the authors notes.

 

Statin users had a higher odds ratio (OR) for musculoskeletal disease diagnosis group 1 (all musculoskeletal diseases: OR, 1.19), for musculoskeletal disease diagnosis group 1b (dislocation/strain/sprain: OR, 1.13) and for musculoskeletal diagnosis group 2 (musculoskeletal pain: OR, 1.09), but not for musculoskeletal disease diagnosis group 1a (osteoarthritis/arthropathy: OR,1.07), according to study results for the propensity score-matched pairs.

 

‘To our knowledge, this is the first study, using propensity score matching, to show that statin use is associated with an increased likelihood of diagnoses of musculoskeletal conditions, arthropathies and injuries. In our primary analysis, we did not find a statistically significant association between statin use and arthropathy; however, this association was statistically significant in all other analyses,” the authors conclude. “These findings are concerning because starting statin therapy at a young age for primary prevention of cardiovascular diseases has been widely advocated.”.

Vegetarian Diets Associated With Lower Risk of Death

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 3, 2013

Media Advisory: To contact Michael J. Orlich, M.D., call Herbert Atienza at 909-558-8419 or email hatienza@llu.edu.


CHICAGO – Vegetarian diets are associated with reduced death rates in a study of more than 70,000 Seventh-day Adventists with more favorable results for men than women, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

The possible relationship between diet and mortality is an important area of study. Vegetarian diets have been associated with reductions in risk for several chronic diseases, including hypertension, metabolic syndrome, diabetes mellitus and ischemic heart disease (IHD), according to the study background.

 

Michael J. Orlich, M.D., of Loma Linda University in California, and colleagues examined all-cause and cause-specific mortality in a group of 73,308 men and women Seventh-day Adventists. Researchers assessed dietary patients using a questionnaire that categorized study participants into five groups: nonvegetarian, semi-vegetarian, pesco-vegetarian (includes seafood), lacto-ovo-vegetarian (includes dairy and egg products) and vegan (excludes all animal products).

 

The study notes that vegetarian groups tended to be older, more highly educated and more likely to be married, to drink less alcohol, to smoke less, to exercise more and to be thinner.

 

“Some evidence suggests vegetarian dietary patterns may be associated with reduced mortality, but the relationship is not well established,” the study notes.

 

There were 2,570 deaths among the study participants during a mean (average) follow-up time of almost six years. The overall mortality rate was six deaths per 1,000 person years.  The adjusted hazard ratio (HR) for all-cause mortality in all vegetarians combined vs. nonvegetarians was 0.88, or 12 percent lower, according to the study results. The association also appears to be better for men with significant reduction in cardiovascular disease mortality and IHD death in vegetarians vs. nonvegetarians. In women, there were no significant reductions in these categories of mortality, the results indicate.

 

“These results demonstrate an overall association of vegetarian dietary patterns with lower mortality compared with the nonvegetarian dietary pattern. They also demonstrate some associations with lower mortality of the pesco-vegetarian, vegan and lacto-ovo-vegetarian diets specifically compared with the nonvegetarian diet,” the authors conclude.

Research Finds Retinal Vessel Leakage During High Altitude Exposure

“Exposure to high altitude can cause acute mountain sickness (AMS) and, in severe cases, cerebral or pulmonary edema. Capillary leakage has been hypothesized to play a role in the pathogenesis of AMS, although the mechanism of altitude-related illnesses remains largely unknown,” writes Gabriel Willmann, M.D., of the University of Tubingen, Germany, and colleagues. “Vessel leakage in the retinal periphery has not been investigated. Our objective was to assess retinal vessel integrity at high altitude using fluorescein angiography.”

As reported in a Researcher Letter, the study included 14 healthy, unacclimatized volunteers (7 male and 7 female participants, average age, 35 years) who were studied at baseline (1,119 feet), after ascent to 14,957 feet within 24 hours, and more than 14 days after return by fluorescein angiography. Photographs were independently graded in random order by 4 ophthalmologists for presence and location of leakage.

Retinal abnormalities were not noted at baseline in any of the participants. At high altitude, marked bilateral leakage of peripheral retinal vessels was observed in 7 of 14 participants (50 percent). All findings completely reversed after descent. “Retinal capillary leakage should be considered a part of the spectrum of high-altitude retinopathy,” the authors write.

The Morality of Using Mortality as a Financial Incentive – Unintended Consequences and Implications for Acute Hospital Care

In this Viewpoint, Joel M. Kupfer, M.D., of Methodist Medical Center and the University of Illinois College of Medicine-Peoria, examines the potential issues of using financial incentives to improve hospital mortality rates.

“Financial incentives can be powerful motivators but the results might not always be beneficial. Changes in program design and more widespread implementation might help overcome prior limitations but the potential for unintended consequences also may increase as the financial imperatives of hospitals to win incentives increases. It is important to move ahead with quality initiatives even though there are gaps in current knowledge. The challenge for policy makers will be to design a balanced system that can lower costs and improve care while preserving the ethical integrity of the medical profession, and respect patients’ rights to make choices about their health care.”

 The Future of Quality Measurement for Improvement and Accountability

“The Affordable Care Act expands access to health insurance and includes numerous provisions focused on delivering care that is high quality, safe, and affordable. Reliable and meaningful quality measurement that focuses on important outcomes, including patient experience throughout the health care system, is an essential prerequisite for achieving this goal,” writes Patrick H. Conway, M.D., M.Sc., of the Department of Health and Human Services, Washington, D.C., and the Centers for Medicare & Medicaid Services, Baltimore, and colleagues.

In this Viewpoint, the authors “describe the characteristics of the quality measurement enterprise of the future, outline a potential roadmap for the transition, and identify a set of opportunities for public- and private-sector collaboration.”

“As measures are increasingly implemented in payment programs based on value, the public and private sectors must collectively work to ensure the implementation of patient-centered measures that matter, minimize clinician burden, focus on improvement, and develop an agile learning measurement enterprise. The measurement enterprise is critical for successful transformation of the health system to achieve better health outcomes as efficiently as possible.”

Synthesizing Evidence – Shifting the Focus From Individual Studies to the Body of Evidence

“The research enterprise behaves as if a single study could provide the ultimate answer to a clinical question,” write M. Hassan Murad, M.D., M.P.H., and Victor M. Montori, M.D., M.Sc., of the Mayo Clinic, Rochester, Minn. “Researchers offer over optimistic sample-size calculations and other design features to convince funders and institutional review boards that their study will provide the answer. Medical journals and the popular media highlight single studies, too often without regard to similar studies.”

Researchers with the Cochrane Centre have advocated for the results of individual studies to be placed in the context of the totality of evidence for the last 15 years, with limited success.  In this Viewpoint, the authors offer reasons to shift the collective focus from single studies to the accumulating body of evidence.

Study Finds Little Evidence Supporting Use of Bariatric Surgical Procedures for Non-Morbidly Obese Adults With Diabetes or Glucose Intolerance

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 4, 2013

Media Advisory: To contact Melinda Maggard-Gibbons, M.D., M.S.H.S., call Warren Robak at 310-451-6913 or email robak@rand.org.


CHICAGO – A review of more than 50 studies found limited evidence supporting the use of bariatric surgical procedures for non-morbidly obese adults (body mass index [BMI] 30-35) with diabetes or impaired glucose intolerance, according to a study in the June 5 issue of JAMA. For the limited data that was available for this patient group, bariatric surgery was associated with greater improvements in short-term weight loss, intermediate blood glucose levels, blood pressure, and high cholesterol than nonsurgical interventions such as medications, diet, and behavioral changes.

“Bariatric surgery is often used to promote weight loss and manage obesity-related comorbidities [co-existing illnesses] in morbidly obese patients (body mass index [BMI; 35 or greater]). In this population, procedures such as laparoscopic adjustable gastric banding and Roux-en-Y gastric bypass have resulted in better glucose control and more weight loss at 1 or 2 years than nonsurgical therapy,” according to background information in the article. “Bariatric surgical procedures are being advocated as a treatment for diabetes in less-obese individuals (BMI, 30-35). However, this practice remains controversial. In 2006, the Centers for Medicare & Medicaid Services would not approve coverage for patients with lower BMI and diabetes, whereas the U.S. Food and Drug Administration has approved gastric banding for individuals with a BMI of 30 to 35 who have an obesity-related comorbidity.”

Melinda Maggard-Gibbons, M.D., M.S.H.S., of Rand Health, Santa Monica, Calif., and colleagues conducted a systematic review of the relative benefits and risks associated with surgical and nonsurgical therapies for treating diabetes or impaired glucose tolerance in patients with a BMI of 30 to 35. The authors conducted a search of the medical literature and identified 32 surgical studies, 11 systematic reviews on nonsurgical treatments, and 11 large non-surgical studies published after those  reviews that met criteria for the analysis.

The researchers found that bariatric surgery was associated with greater weight loss (range, 32-53 lbs.) and glycemic control during 1 to 2 years of follow-up than nonsurgical treatment in only three randomized clinical trials (RCTs; n=290). None of these trials had substantial numbers of patients meeting the study criteria: 1 trial of 150 patients with type 2 diabetes and an average BMI of 37; 1 trial of 80 patients without diabetes and BMI of 30 to 35; and 1 trial of 60 patients with diabetes and BMI of 30 to 40 [13 patients with BMI <35]).

Bariatric surgery seemed to be associated with weight loss and diabetes control in observational studies having 1 or 2 years of follow-up with indirect comparisons of evidence (approximately 600 patients) and meta-analyses of nonsurgical therapies (containing more than 300 RCTs).

Surgeon-reported adverse events were low (e.g., hospital deaths of 0.3 percent-1.0 percent), but data were from select centers and surgeons. Long-term adverse events are unknown.

“… there are limited data from clinical trials in this specific patient population, and it is unknown whether the benefits observed are durable long-term and if these findings might translate into reductions in the microvascular and macrovascular complications of diabetes. Until such data are available, the evidence is insufficient to reach conclusions about the appropriate use of bariatric surgery in this patient population, performance of these procedures in this target population should be under close scientific scrutiny, and additional studies comparing procedures are warranted,” the authors conclude.

Gastric Bypass Surgery May Help Manage Diabetes Risk Factors

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, JUNE 4, 2013

Media Advisory: To contact Sayeed Ikramuddin, M.D., call Matt DePoint at 612-625-4110 or email mdepoint@umn.edu. To contact editorial author Bruce M. Wolfe, M.D., call Mirabai Vogt at 503-494-7986 or email vogtmi@ohsu.edu.


CHICAGO – Among mild to moderately obese patients with type 2 diabetes, adding gastric bypass surgery to lifestyle and medical management was associated with a greater likelihood of improved levels of metabolic risk factors such as blood glucose, LDL-cholesterol and systolic blood pressure, according to a study in the June 5 issue of JAMA.

“The foundation of treatment for type 2 diabetes mellitus is weight loss, achieved through reduction of energy intake and increased physical activity via lifestyle modification. Results from the Look AHEAD (Action for Health in Diabetes) trial show that sustained weight loss through lifestyle modification improves diabetes control, but this is difficult to achieve and maintain over time,” according to background information in the article. “Controlling glycemia, blood pressure, and cholesterol is important for patients with diabetes. How best to achieve this goal is unknown.”

Sayeed Ikramuddin, M.D., of the University of Minnesota, Minneapolis, and colleagues conducted a study to compare Roux-en-Y gastric bypass with lifestyle and intensive medical management to achieve control of comorbid (co-existing) risk factors. The 12-month, 2-group randomized trial was conducted at 4 teaching hospitals in the United States and Taiwan and included 120 participants who had a hemoglobin A1c (HbA1c) level of 8.0 percent or higher, body mass index (BMI) between 30.0 and 39.9, C peptide level of more than 1.0 ng/mL, and type 2 diabetes for at least 6 months. The study began in April 2008. The interventions for the trial were lifestyle-intensive medical management intervention and Roux-en-Y gastric bypass surgery. Medications for hyperglycemia, hypertension, and dyslipidemia were prescribed according to protocol and surgical techniques that were standardized.

The composite goal for the study was the goal established by the American Diabetes Association (ADA) for the treatment of diabetes: HbA1c less than 7.0 percent, low-density lipoprotein cholesterol less than 100 mg/dL, and systolic blood pressure less than 130 mm Hg.

All 120 patients received the Look AHEAD intensive lifestyle-medical management protocol, the protocol used in the Look AHEAD study and considered to be the most successful for treating diabetes in obese patients; 60 of the 120 patients were randomly assigned to undergo Roux-en-Y gastric bypass. The researchers found that at 12 months, 11 participants (19 percent) in the lifestyle-medical management group and 28 (49 percent) in the gastric bypass group achieved the primary composite end point. Among the composite end point components, the only significant treatment effect was for HbA1c: 18 participants (32 percent) in the lifestyle-medical management group vs. 43 (75 percent) in the gastric bypass group achieved an HbAlc level of less than 7 percent.

The lifestyle-medical management group lost an average of 7.9 percent of initial body weight at 1 year, whereas the average weight loss in the gastric bypass group was 26.1 percent. “On average, the gastric bypass group used 3.0 fewer medications to manage glycemia, dyslipidemia, and hypertension than did those in the lifestyle-medical management group. The gastric bypass group also had significantly better results for the secondary outcomes of glycemia, HDL cholesterol, triglycerides, and diastolic blood pressure,” the authors write.

Analyses indicated that achieving the composite end point was primarily attributable to weight loss. The gastric bypass group experienced more nutritional deficiency than the lifestyle-medical management group. Overall, there were 22 serious adverse events in the gastric bypass group and 15 in the lifestyle-medical management group.

This study overcame limitations of prior studies of bariatric surgery by using a widely accepted nonsurgical treatment protocol, used endpoints recommended as the major goal for treatment by the ADA, was performed by multiple surgeons of different hospitals and studied a single operative procedure, the Roux-en-Y gastric bypass, considered to be the best procedure for weight loss.

“The merit of gastric bypass treatment of moderately obese patients with type 2 diabetes depends on whether potential benefits make risks acceptable. Bariatric surgery can result in dramatic improvements in weight loss and diabetes control in moderately obese patients with type 2 diabetes who are not successful with lifestyle changes or medical management. The benefits of applying bariatric surgery must be weighed against the risk of serious adverse events,” the researchers conclude.

Editorial: Treating Diabetes With Surgery

In an accompanying editorial, Bruce M. Wolfe, M.D., of Oregon Health and Science University, Portland, and colleagues comment on the two articles in this issue of JAMA regarding weight loss surgery and diabetes.

“Recent large scale trials of intensive medical management for obesity and diabetes have been disappointing. Substantial resources are required to cause modest weight loss and diabetes control. Bariatric surgery does result in substantial weight loss with excellent diabetes control but is offset by initial high cost and risks for surgical complications. The optimal approach for treatment of obesity and diabetes remains unknown. The answer will only come from more well designed, randomized trials such as that performed by Ikramuddin et al that provide definitive answers.”

Study Examines Relationship of Early Life Risk Factors And Racial/Ethnic Disparities in Childhood Obesity

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 3, 2013

Media Advisory: To contact Elsie M. Taveras, M.D., M.P.H., call Kory Dodd Zhao at 617-726-0274 or email kzhao2@partners.org.


CHICAGO – Racial and ethnic disparities in children who are overweight and obese may be determined by risk factors in infancy and early childhood, according to a study published Online First by JAMA Pediatrics, a JAMA Network publication.

 

Over three decades, the rates of overweight and obesity among children have substantially increased worldwide. In the United States, the prevalence is estimated to be 32 percent among children and adolescents, according to the study background.

 

Elsie M. Taveras, M.D., M.P.H., now of the MassGeneral Hospital for Children, Boston, and colleagues examined which racial and ethnic disparities were explained by factors during pregnancy (gestational diabetes and depression), infancy (rapid infant weight gain, feeding other than exclusive breastfeeding and early introduction of solid foods), and early childhood (sleeping less than 12 hours per day, a television in the room where the child sleeps and any intake of sugar-sweetened beverages or fast food). Study participants included 1,116 mother-child pairs (63 percent white, 17 percent black and 4 percent Hispanic.

 

“Many early life risk factors for childhood obesity are more prevalent among blacks and Hispanics than among whites and may explain the higher prevalence of obesity among racial/ethnic minority children,” the study notes.

 

Black and Hispanic children had higher body-mass index (BMI) z scores, along with higher total fat mass index and overweight/obesity prevalence than white children. Differences in the BMI z score were attenuated (reduced) for black and Hispanic children when adjustments were made for socioeconomic confounders and parental BMI. But adjustments for pregnancy risk factors did not appear to substantially change these estimates.

 

However, there appeared to be only minimal differences in BMI z scores between whites, blacks and Hispanics when further adjustments were made for infancy and childhood risk factors, the results indicate.

 

“We found that the prevalence of overweight and obesity among black and Hispanic children at age 7 years was almost double that of white children. … Our findings suggest that racial/ethnic disparities in childhood obesity may be explained by factors operating in infancy and early childhood and that eliminating these factors could eliminate the disparities in childhood obesity,” the authors conclude.

JAMA Pediatrics Study Highlights


A study by Helen Wong, R.D., of The Hospital for Sick Children, Ontario, Canada, and colleagues examined the safety and efficacy of dietary flaxseed supplementation in the management of hypercholesterolemia (high levels of cholesterol) in children. (Online First)

 

The randomized clinical trial included 32 participants ages 8 to 18 years with low-density lipoprotein cholesterol levels ranging from 135 mg/dL to less than 193 mg/dL. Participants were randomly assigned to either the intervention group or control group. The intervention group ate 2 muffins and 1 slice of bread daily containing flaxseed (30 grams flaxseed total). The control group ate muffins and bread substituted with whole-wheat flour.

 

According to the study results, flaxseed had no significant effects on total cholesterol, low-density lipoprotein cholesterol levels or total caloric intake. The change in total and low-density lipoprotein cholesterol levels failed to exclude a potential benefit of flaxseed supplementation based on a prespecified minimum clinically important reduction of 10 percent.

 

“Until its relevance is clearly understood, flaxseed supplementation remains an unverified strategy for the clinical management of cardiovascular risk factors in youth with hyperlipidemia,” the study concludes.

Interleukin 17F Level and Interferon Beta Response in Patients With Multiple Sclerosis

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, JUNE 3, 2013

Media Advisory: To contact study author Hans-Peter Hartung, M.D., email HansPeter.Hartung2012@gmail.com.

JAMA Neurology Study Highlights


A study by Hans-Peter Hartung, M.D., of Heinrich-Heine-Universität, Düsseldoft, Germany, and colleagues examines the association between IL-17F and treatment response to interferon beta-1b among patients with relapsing-remitting multiple sclerosis. (Online First)

 

Serum samples were analyzed with an immunoassay from 239 randomly selected patients treated with interferon beta-1b, 250 micrograms, for at least 2 years in the Betaferon Efficacy Yielding Outcomes of a New Dose Study. Researchers measured the levels of IL-17F at baseline and month 6, as well as the difference between the IL-17F levels at month 6 and baseline were compared between: (1) patients with less disease activity versus more disease activity; (2) patients with no disease activity versus some disease activity; and (3) responders versus nonresponders.

 

According to study results, levels of IL-17F measured at baseline and month 6 did not correlate with lack of response to treatment after 2 years using clinical and magnetic resonance imaging (MRI) criteria. Relapses and new lesions on MRI were not associated with pretreatment serum IL-17F levels. When patients with neutralizing antibodies were excluded, the results did not change.

 

“We found that serum concentrations of IL-17F alone did not predict response to interferon beta-1b therapy in patients with relapsing-remitting multiple sclerosis.” The study concludes, “Given the multifaceted pathophysiology associated with disease progression and response to treatment by patients with relapsing-remitting multiple sclerosis, using extreme patient cohorts in combination with immune-based biomarker signatures may actually be the most efficient way of initially identifying response markers.”

Study Suggests Cost-Effectiveness of Resident-Performed Cataract Surgery for Uninsured Patients

EMBARGOED FOR RELEASE: 3 P.M. (CT), THURSDAY, MAY 30, 2013

Media Advisory: To contact corresponding author Mark A. Slabaugh, M.D., call Elizabeth Hunter at 206-616-3192 or email elh415@uw.edu.


CHICAGO – A study at a Seattle hospital suggests that supervised, resident-performed cataract surgery is successful and cost-effective in an underserved patient population, according to a report published Online First by JAMA Ophthalmology, a JAMA Network publication.

 

The literature regarding resident physician influence on patient cost and surgical outcomes is inconclusive, Daniel B. Moore, M.D., and Mark A. Slabaugh, M.D., of the University of Washington, Seattle, write in the study background.

 

The study included 143 consecutive uninsured patients undergoing cataract procedures performed by attending-supervised resident physicians at the University of Washington from July 2005 through June 2011.

 

The patients’ mean (average) preoperative best-corrected visual acuity (BCVA) was 1.09 (Snellen equivalent, 20/300). The final recorded mean BCVA was 0.27 (Snellen equivalent, 20/40) at a median (midpoint) follow-up of 16 months. The average health care cost per patient was $3,437, according to the study results.

 

“These data support the success and cost-effectiveness of supervised, resident-performed cataract surgery in an underserved patient population. This study lends support for continuing this traditional scheme of surgical training and education,” the authors conclude.

Weight Loss May Improve Psoriasis Symptoms in Overweight Patients

Weight Loss May Improve Psoriasis Symptoms in Overweight Patients

 

CHICAGO – A low-calorie diet that leads to weight loss may be associated with improved psoriasis symptoms in overweight patients, according to a report published Online First by JAMA Dermatology, a JAMA Network publication.

 

Psoriasis is a chronic inflammatory skin disease with a prevalence of about 2 percent in Northern Europe and North America. The role of weight loss as a treatment for psoriasis in obese patients is unclear. But, weight loss may reduce obesity-induced inflammation and that in turn may improve the skin disease, the authors write in the study background.

 

Peter Jensen, M.D., Ph.D., of the Copenhagen University Hospital Gentofte, Denmark, and colleagues conducted a randomized clinical trial with 60 obese patients with psoriasis. The patients were randomly assigned into two groups: an intervention group that followed a low-energy (calorie) diet (LED,  800-1,000 kilocalories/per day) and a control group that continued to eat ordinary healthy foods. The main outcomes researchers measured were the Psoriasis Area and Severity Index (PASI) after 16 weeks and the Dermatology Life Quality Index (DLQI).

 

“Treatment with an LED showed a trend in favor of clinically important PASI improvement and a significant reduction in DLQI in overweight patients with psoriasis,” according to the study.

 

At baseline, the median (midpoint) PASI was 5.4. At week 16, the mean (average) body weight loss was almost 34 pounds (15.4 kg) greater in the intervention group than in the control group. The mean differences in PASI and DLQI, which also favored the intervention group, were -2.0 and -2.0, respectively, according to the study results. The study notes that the mean between-group difference in PASI of -2.0 did not reach statistical significance.

 

“Our results emphasize the importance of weight loss as part of a multimodal treatment approach to effectively treat both the skin condition and its associated comorbid conditions in overweight patients with psoriasis,” the authors conclude.

Review of Venous Thromboembolism Prevention Methods After Bariatric Surgery

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 29, 2013

Review of Venous Thromboembolism Prevention Methods After Bariatric Surgery  

CHICAGO – A review of available medical literature suggests there is insufficient evidence to support the use of intra-vascular filters or augmented dosing of anti-clotting medication in patients undergoing bariatric surgery to prevent venous thromboembolism (VTE, blood clots), according to a report published Online First by JAMA Surgery, a JAMA Network publication.

 

Prophylaxis to prevent VTE is recommended for patients undergoing abdominal surgery, according to the study background.

 

Daniel J. Brotman, M.D., and colleagues of The Johns Hopkins University, Baltimore, included 13 studies in their review; five of the studies had patients with and without filters placed in the inferior vena cava, the large vein through which blood from the legs and pelvis flows back to the heart and eight had patients receiving different pharmacologic regimens.

 

The authors note they found no randomized clinical trials addressing the comparative effectiveness of different interventions to prevent VTE among patients undergoing bariatric surgery so all the studies were observational in nature.

 

“Overall, our findings support the use of ‘standard’ doses of pharmacotherapy as prophylaxis for patients undergoing bariatric surgery, consistent with current American College of Chest Physicians guidelines, which do not distinguish between patients undergoing bariatric surgery and those undergoing other types of abdominal surgery,” the authors conclude. “We found no evidence to support filter placement as prophylaxis in patients undergoing bariatric surgery, with a trend toward higher DVT [deep vein thrombosis] rates and higher mortality in patients receiving filters.”

CHICAGO – An analysis of top box-office movies released in the United States indicated tobacco brand producer placements in movies have declined since implementation of the Master Settlement Agreement (MSA), but alcohol placements, which are subject only to industry self-regulation, have increased in movies rated acceptable for youth audiences, according to a study published Online First by JAMA Pediatrics, a JAMA Network publication.

 

There is growing evidence that movies influence substance use behaviors during adolescence. Children’s exposure to movie imagery of tobacco and alcohol has been associated with not only smoking but also early onset of drinking, heavier drinking and abuse of alcohol, according to the study background.

 

Elaina Bergamini, M.S., of the Geisel School of Medicine at Dartmouth University, New Hampshire, and colleagues examined recent trends for tobacco and alcohol use in movies. The study analyzed the top 100 box-office movie hits released in the United States from 1996 through 2009 (N=1400).

 

After implementation of the MSA in 1998, tobacco brand product appearances decreased by 7 percent each year, then held at a level of 22 per year after 2006. The MSA also resulted in a decrease in tobacco screen time for youth and adult rated movies (42.3 percent and 85.4 percent, respectively). Alcohol brand product appearances in youth-rated movies trended upward during the period from 80 to 145 per year, an increase of 5.2 appearances per year.

 

“In summary, this study found dramatic declines in brand appearances for tobacco after such placements were prohibited by an externally monitored and enforced regulatory structure, even though such activity had already been prohibited in the self-regulatory structure a decade before. During the same period, alcohol brand placements, subject only to self-regulation, increased significantly in movies rated acceptable for youth audiences, a trend that could have implications for teen drinking,” the study concludes.

Use of Stimulant Medication in Childhood Not Associated with Increased Risk of Substance Use Disorders in Adulthood, Study Suggests

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, May 29, 2013

Use of Stimulant Medication in Childhood Not Associated with Increased Risk of Substance Use Disorders in Adulthood, Study Suggests

 

CHICAGO – The treatment of attention-deficit/hyperactivity disorder (ADHD) with stimulant medication is not associated with either an increased or decreased risk of later substance use disorders, according to a meta-analysis published Online First by JAMA Psychiatry, a JAMA Network publication.

 

The use of medication, most often with stimulant medication (eg, methylphenidate and mixed amphetamine salts), is a well-established treatment for ADHD and constitutes the first-line ADHD treatment in many clinical settings. The use of stimulant medication to treat ADHD remains controversial given concerns about its potential for abuse and possible role in sensitizing patients to later substance problems, the authors write in the study background.

 

Kathryn L. Humphreys, M.A., Ed.M., of the University of California, Los Angeles, and colleagues examined the longitudinal association between treatment with stimulant medication during childhood for ADHD and later substance outcomes (i.e. lifetime substance use and substance abuse or dependence).

 

The meta-analysis included studies with longitudinal designs in which medication treatment preceded the measurement of substance outcomes and that were published between January 1980 and February 2012. Odds ratios were obtained for lifetime use (ever used) and abuse or dependence status for alcohol, cocaine, marijuana, nicotine, and nonspecific drugs for 2,565 participants from 15 different studies.

 

Separate random-effects analyses were conducted for each substance outcome. Results suggested comparable outcomes between children with and without medication treatment history for any substance use and abuse or dependence outcome across all substance types.

 

“These results provide an important update and suggest that treatment of attention-deficit/hyperactivity disorder with stimulant medication neither protects nor increases the risk of later substance use disorders,” the study concludes.

Increase in Unintentional Marijuana Ingestion Among Young Children Following New Drug Laws in Colorado

 

CHICAGO —    Following modification of drug enforcement laws for possession of marijuana in Colorado, there was an apparent increase in unintentional marijuana ingestions by young children, according to a report and accompanying editorials published Online First by JAMA Pediatrics, a JAMA Network publication.

 

Several states and Washington, D.C. have enacted laws to decriminalize medical marijuana and two states, Colorado and Washington, have passed amendments to legalize the recreational use of marijuana.  In late 2009, the Justice Department issued a policy instructing federal prosecutors not to seek arrest of medical marijuana users and suppliers, if they were complying by state laws.  According to background information in the study, tetrahydrocannabinol, the active chemical in marijuana, is incorporated into medical marijuana products in higher concentrations. “In addition, medical marijuana is sold in baked goods, soft drinks, and candies,” the authors note.

 

George Sam Wang, M.D, from the Rocky Mountain Poison and Drug Center, Denver, and colleagues compared the proportion of marijuana ingestions by young children who sought care in a children’s hospital emergency department before and after the modification of drug enforcement laws in October 2009 regarding medical marijuana possession.  A total of 1,378 patients younger than 12 years of age were evaluated for unintentional ingestions:  790 patients before September 30, 2009 and 588 patients after October 1, 2009.

 

“The proportion of ingestion visits in patients younger than 12 years (age range 8 months to 12 years) that were related to marijuana exposure increased after September 30, 2009, from 0 of 790 to 14 of 588,” the authors report.   “Eight of the 14 cases involved medical marijuana, and 7 of these exposures came from food products.”    The authors note most of the children were male and were admitted to or observed in the emergency department.   “Because of a perceived stigma associated with medical marijuana, families may be reluctant to report its use to health care providers. Similar to many accidental medicinal pediatric exposures, the source of the marijuana in most cases was the grandparents who may not have been available during data collection.”

 

“Physicians, especially in states that have decriminalized medical marijuana, need to be cognizant of the potential for marijuana exposures and be familiar with the symptoms of marijuana ingestion.  This unintended outcome may suggest a role for public health interventions in this emerging industry, such as child-resistant containers and warning labels for medical marijuana,” the authors conclude.

Editorial:  Effects of Marijuana Policy on Children and Adolescents

 

In an accompanying editorial, Sharon Levy, M.D., M.P.H., from Harvard Medical School and Boston Children’s Hospital, writes that “the finding reignites the debate over whether and how legalized marijuana impacts children and adolescents.”

 

Dr. Levy reports that nationwide rates of adolescent marijuana use are climbing rapidly.  “The skyrocketing rates of adolescent marijuana use indicate that we are losing an important public health battle and we have a lot of work to do if we want to reverse these trends.  Physicians have a key role to play in educating our young patients and their families about the health consequences of marijuana use regardless of its legal status.”

Editorial:  Anticipated Medical Effects on Children:  A Poison Center Perspective

“The legalization of recreational marijuana, especially the solid and liquid-infused forms permitted in Washington, will provide children greater access to cookies, candies, brownies, and beverages that contain marijuana,” write William Hurley, M.D., from the University of Washington and Washington Poison Center and Suzan Mazor, M.D., from Seattle Children’s Hospital.

 

“Ingestion of marijuana results in the absorption of delta-9-tetrahydrocannibinol (THC) and stimulation of cannabinoid receptors in the central nervous system.  This produces stimulation with hallucinations and illusions followed by sedation,” the authors state.    The authors recommend additional training for emergency medicine, pediatric emergency medicine and primary care pediatric physicians to recognize and manage these toxic reactions.

 

“Methods to prevent accidental exposures to marijuana need to be studied for efficacy and progressively developed.  Parents and providers should be encouraged to call the Poison Center for data collection, information, education, and management advice,” the authors conclude.

Overuse of Health Care Services

When Less is More…More or Less

 

Allison Lipitz-Snyderman, Ph.D., and Peter B. Bach, M.D., M.A.P.P. from Memorial Sloan-Kettering Cancer Center, New York, discuss benefit-harm tradeoff, benefit-cost tradeoff, and consideration of patient preference, in the delivery of high-quality health care and addressing overuse of services.

 

When Previously Expressed Wishes Conflict with Best Interests

 

Alexander K. Smith, M.D., M.S., M.P.H., Bernard Lo, M.D., and Rebecca Sudore, M.D., from the University of California, San Francisco, describe two cases that involve the decision-making process for surrogates of patients with advance directives.  In some cases the advance directives may conflict with what physicians or the surrogates view as in the patient’s best interest for those patients who have lost decision-making capacity.

 

The Challenge to the Medical Record

 

Robert S. Foote, M.D., from Dartmouth Hitchcock Medical Center, Lebanon, New Hampshire, writes:  “The medical record has become a battleground where part of a larger struggle over the nature, purposes, and future of health care is taking place.  I believe it is essential for physicians to defend this ground.”

JAMA Internal Medicine Publishes Several Articles on Shared Decision Making Between Physicians and Patients

**************************************************************************

 

Communication Between Physicians and Patients Important for Expectations

 

CHICAGO — Seriously ill patients undergoing hemodialysis are more optimistic about their prognosis and prospects for transplants than their nephrologists, according to a study published online by JAMA Internal Medicine. The study also found that nephrologists rarely had discussed estimates of life-expectancy with their patients.

 

Melissa W. Wachterman, M.D., M.P.H., from Veterans Affairs Boston Health Care System and colleagues compared patients’ and physicians’ expectations about one- and five-year survival rates and transplant candidacy among 207 patients undergoing hemodialysis through medical record reviews and interviews.  “Among the 62 interviewed patients, no patients reported that their nephrologist had discussed an estimated life expectancy with them, and the nephrologists reported that they had done so for only two interviewed patients,” the authors found.    The nephrologists reported that “…for 60 percent of patients, they would not provide any estimate of prognosis even if their patient insisted.”     The authors note that patients’ expectations about one-year survival rates are fairly accurate, but that patients over-estimate their long-term survival rates.

 

“As our ability to accurately prognosticate for seriously ill patients continues to advance, developing interventions to help providers communicate effectively with patients about prognosis will become increasingly important,” the authors conclude.

Patient Participation in Decision Making Associated With Increased Costs, Services

 

CHICAGO – A survey of almost 22,000 admitted patients at the University of Chicago Medical Center found patient preference to participate in decision making concerning their care was associated with a longer length of stay and higher total hospitalization costs, according to a report published online by JAMA Internal Medicine.

 

Hyo Jung Tak, Ph.D., and colleagues examined the relationship between patient preferences for participation in medical decision making and health care utilization among patients hospitalized between July 1, 2003 and August 31, 2011 by asking patients to complete a survey.  The survey data were then linked with administrative data, including length of stay and total hospitalization costs.  Nearly all of the patients indicated they wanted information about their illnesses and treatment options, but just over 70 percent preferred to leave the medical decisions to their physician.  “Preference to participate in medical decision making increased with educational level and with private health insurance,” the authors note.   “…patients who preferred to participate in decision making concerning their care had a 0.26-day longer length of stay and $865 higher total hospitalization costs.”

 

In conclusion the authors write: “That patient preference for participation is associated with increased resource use contrasts with some perspectives on shared decision making that emphasize reductions of inappropriate use. However, in the presence of physician incentives to decrease use, such as exist for hospitalized patients and are likely to increase under health reform, increased resource use may occur.  Future studies related to patient participation in decision making should examine effects on both outcomes and costs.”

How Patient Centered are Medical Decisions?

 

CHICAGO —   A national survey sample of adults who had discussions with their physicians in the preceding two years about common medical tests, medications and procedures often did not reflect a high level of shared decision making, according to an article published online by JAMA Internal Medicine.

 

Floyd J. Fowler, Jr., Ph.D., from the Informed Medical Decisions Foundation and the University of Massachusetts, Boston, conducted a 2011 survey of a cross section of U.S. adults 40 years or older and asked them to indicate whether they reported making one of 10 medical decisions and to describe their interactions with their physicians concerning those decisions.   The decisions included: medication for hypertension, elevated cholesterol, or depression; screening for breast, prostate or colon cancer; knee or hip replacement for osteoarthritis, or surgery for cataract or low back pain.

 

“…we saw great variation in the extent to which patients reported efforts to inform them about and involve them in 10 common decisions,” the authors write in their conclusion.  “Although there was variation within decision types, decisions concerning four surgical procedures were much more shared than decisions about cancer screening and two very common long-term medications for cardiac risk reduction.  If share decision making is to be one defining characteristic of primary care as delivered in medical homes, primary care physicians and other health care providers will need to balance their discussions of pros and cons to a greater degree and ask patients for their input more consistently.”

Decision Making Preferences Among Patients with Heart Attacks

 

CHICAGO – In a research letter, Harlan M. Krumholz, M.D., S.M., from Yale University School of Medicine and colleagues, “sought to investigate preferences for participation in the decision-making process among individuals hospitalized with an acute myocardial infarction ([AMI] or heart attack).”   The researchers combined data from two similar AMI registries (TRIUMPH and PREMIER) which resulted in 6,636 patients in the study sample who were asked about who should make decisions on treatment options.

 

“More than two-thirds of patients with AMI indicated a preference to play an active role in the decision-making process, and of those, about a quarter preferred that the decision be theirs alone rather than shared with their physician,” the authors found.   “Our findings indicate that physicians who aspire to provide patient-centered care should assess patients’ decision-making preferences by directly asking each patient.”

 

“Our challenge now is to develop systems that fully respect these preferences and ensure that patients who prefer an active role are given that opportunity,” the authors conclude.

Commentary:  Shared Decision Making

 

In an invited commentary, Mack Lipkin, M.D., from NYU Langone School of Medicine, New York City, reviews several of the studies being published online by JAMA Internal Medicine on this topic. Lipkin writes that “shared decision making in the modern era began as informed decision making, a reverse reification of informed consent promulgated in President Reagan’s Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research.”

 

“I believe a series of prospective studies is needed, starting with taped interviews, to validate current notions of what embodies SDM (shared decision-making), to establish how framing and contextual features alter recollections, and to relate accurately and validly measured strong and weak SDM to the evolution of recalled views about the decisional process.  Such results could then be related to health outcomes.”

Research Letter Evaluates Relationship Between Glucosamine Supplementation and Increased Intraocular Pressure in Patients with Glaucoma

EMBARGOED FOR RELEASE: 3 P.M. (CT), THURSDAY, MAY 23, 2013

JAMA Ophthalmology Study Highlights


In a research letter, Ryan K. Murphy, D.O., M.A., of the University of New England College of Osteopathic Medicine, Biddeford, Maine, and colleagues examined the relationship between glucosamine supplementation and increased intraocular pressure (IOP) in patients with glaucoma. (Online First)

 

Many people take a combination of the supplements glucosamine and chondroitin sulfate for osteoarthritis.

 

A total of 17 patients (6 men, 11 women, average age, 76 years) were included in the retrospective study, and were divided in to two groups: group A with between 1 and 3 previously measured baseline IOPs who then began glucosamine supplementation; and group B without preexisting IOP measurements prior to beginning glucosamine. Patients had been selected by their history of glucosamine supplementation and ocular hypertension (IOP >21 mm Hg) or established diagnosis of open-angle glaucoma, willingness to electively stop using glucosamine, IOP measurements at least 3 times within 2 years, and no associated changes in glaucoma medications or eye surgery.

 

In Group A (n=11), IOP increased significantly from before glucosamine supplementation and decreased significantly from during glucosamine. In group B (n=6), IOP significantly decreased in the discontinuation group. In groups A and B combined, patients discontinuing glucosamine supplementation had significantly decreased IOP. There was no significant difference between the left and right eyes in each patient for any of the categories or comparisons.

 

“Many questions are raised by glucosamine supplementation-associated IOP changes. This study shows a reversible effect of those changes, which is reassuring. However, the possibility that permanent damage can result from prolonged use of glucosamine supplementation is not eliminated,” the authors conclude.

JAMA Psychiatry Study Highlights


A study by Mark A. Ilgen, Ph.D, of the Veterans Affairs Serious Mental Illness Treatment Resource and Evaluation Center, Ann Arbor, Michigan and colleagues examined the associations between clinical diagnosis of noncancer pain conditions and suicide. (Online First)  

 

Data for this retrospective analysis were extracted from the National Death Index and treatment records from the Department of Veterans Affairs Healthcare System. Researchers identified 4,863,036 individuals who received services in fiscal year 2005 and were alive at the start of fiscal year 2006. The data were examined for associations between baseline clinical diagnoses of pain-related conditions (arthritis, back pain, migraine, neuropathy, headache or tension headache, fibromyalgia, and psychogenic pain (which results from psychological factors) and subsequent suicide death (assessed in fiscal years 2006-2008).

 

Elevated suicide risks were observed for each pain condition except arthritis and neuropathy. When analyses controlled for accompanying psychiatric conditions, the associations between pain conditions and suicide death were reduced; however, significant associations remained for back pain, migraine, and psychogenic pain, the study finds.

 

“There is a need for increased awareness of suicide risk in individuals with certain noncancer pain diagnoses, in particular back pain, migraine, and psychogenic pain,” the study concludes.

JAMA Dermatology Study Highlights


A study by Kathie P. Huang, M.D., of Brigham and Women’s Hospital, Boston, and colleagues examined the prevalence of comorbid (co-existing) conditions among patients with alopecia areata (AA), an autoimmune disease that presents with nonscarring hair loss from some or all hair-bearing areas of the body, typically the scalp. (Online First)

 

The retrospective cross-sectional study identified 3,568 individuals with AA seen in the Partners Healthcare System in Boston between January 2000 and January 2011. Researchers measured the prevalence of comorbid conditions among those diagnosed with AA.

 

Common comorbid conditions included autoimmune diagnoses: thyroid disease in 14.6 percent, diabetes mellitus in 11.1 percent, inflammatory bowel disease in 6.3 percent, systemic lupus erythematosus in 4.3 percent, rheumatoid arthritis in 3.9 percent, and psoriasis and psoriatic arthritis in 2.0 percent, allergic hypersensitivity: allergic rhinitis, asthma, and/or eczema in 38.2 percent and contact dermatitis and other eczema in 35.9 percent, and mental health problems: depression or anxiety in 25.5 percent. Researchers also found high prevalences of hyperlipidemia (high cholesterol levels, 24.5 percent), hypertension (high blood pressure, 21.9 percent), and gastroesophageal reflux disease [GERD] (17.3 percent).

 

“We found a high prevalence of comorbid conditions among individuals with AA presenting to academic medical centers in Boston. Physicians caring for patients with AA should consider screening for comorbid conditions” the authors conclude.

Advances in Regulatory Science at the Food and Drug Administration

In this Viewpoint, Bruce M. Psaty, M.D., Ph.D., of the University of Washington, Seattle, and colleagues discuss advances in recent years at the U.S. Food and Drug Administration (FDA) to improve drug evaluation.

“The mark of a highly functional regulatory agency is the timely identification of, and the timely and appropriate response to, safety issues. The FDA’s development of the benefit-risk framework, the creation of the Mini-Sentinel, and the use of Risk Evaluation and Mitigation Strategies (REMS) all deserve praise as key efforts to implement a lifecycle approach to drug evaluation. The optimal use of these new tools nonetheless represents a new challenge for the agency. Adequate funding for the FDA—and additional authorities, such as making REMS assessments enforceable—are essential for the agency to continue to make progress in balancing the need for expeditious approval processes with the need for protecting the health of the public.”

 Medication Nonadherence – A Diagnosable and Treatable Medical Condition

“Medication nonadherence is widely recognized as a common and costly problem. Approximately 30 percent to 50 percent of U.S. adults are not adherent to long-term medications leading to an estimated $100 billion in preventable costs annually,” writes Zachary A. Marcum, Pharm.D., M.S., of the University of Pittsburgh, and colleagues. “How can adherence be improved? We propose that the first step is to view medication nonadherence as a diagnosable and treatable medical condition.”

“Based on identified barriers derived from systematic screening, patient-tailored interventions can be delivered in a safe, effective, and efficient manner, with systematic monitoring over time due to the dynamic process of medication adherence. Consistent with Patient-Centered Outcomes Research Institute goals and priorities, community and patient partners should be identified and included throughout the planning and implementation of future studies. Finally, synergism among multiple disciplines is necessary to successfully improve medication adherence for adults.”

Value of Unique Device Identification in the Digital Health Infrastructure

“In recent years, high-profile cases of medical device failure resulting in patient harm—such as implantable cardioverter-defibrillator leads and metal-on-metal hip implants—have received substantial attention both in the medical literature and popular press. These examples illustrate the need for a more effective system of monitoring device performance and protecting patient safety,” write Natalia A. Wilson, M.D, M.P.H., of Arizona State University, Tempe and Joseph Drozda Jr., M.D., of Mercy Health, Chesterfield, Mo.

In this Viewpoint, the authors discuss the Food and Drug Administration’s (FDA’s) establishment of a Unique Device Identification (UDI) System and the UDI’s Final Rule, expected in June 2013, which “will mandate that manufacturers assign unique identifiers to their marketed devices. In addition to enhancing postmarket surveillance, use of UDI should ensure the ability to track a device across health care settings; support safe and accurate device use; create a standard for device documentation in health information technology systems; enhance recall management; improve efficiency; and support health care cost savings.”

Early Use of Tracheostomy For Mechanically Ventilated Patients Not Associated With Improved Survival

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 21, 2013

Media Advisory: To contact Duncan Young, D.M., email duncan.young@nda.ox.ac.uk. To contact editorial author Derek C. Angus, M.D., M.P.H., call Rick Pietzak at 412-864-4151 or email pietzakr@upmc.edu.


CHICAGO – For critically ill patients receiving mechanical ventilation, early tracheostomy (within the first 4 days after admission) was not associated with an improvement in the risk of death within 30 days compared to patients who received tracheostomy placement after 10 days, according to a study in the May 22/29 issue of JAMA.

“A tracheostomy is commonly performed when clinicians predict a patient will need prolonged mechanical ventilation,” according to background information in the article. The use of this procedure has increased, such that up to one-third of patients requiring prolonged mechanical ventilation now receive tracheostomy. Perceived beneficial effects of tracheostomies might be maximized if the procedure were performed early in a patient’s illness, the authors write. “There is little evidence to guide clinicians regarding the optimal timing for this procedure.”

Duncan Young, D.M., of John Radcliffe Hospital, Oxford, England, and colleagues conducted a study to examine whether early vs. late tracheostomy would be associated with lower mortality among adult patients requiring mechanical ventilation in critical care units. The randomized clinical trial was conducted between 2004 and 2011 at 70 adult general and 2 cardiothoracic critical care units in 13 university and 59 nonuniversity hospitals in the United Kingdom. The study included 909 adult patients receiving mechanical ventilation for less than 4 days and identified by the treating physician as likely to require at least 7 more days of mechanical ventilation. Patients were randomized 1:1 to early tracheostomy (within 4 days) or late tracheostomy (after 10 days if still indicated).

Of the 455 patients assigned to early tracheostomy, 91.9 percent received a tracheostomy and of 454 patients assigned to late tracheostomy, 44.9 percent received a tracheostomy. The researchers found that the primary outcome, all-cause mortality 30 days from randomization, was not statistically different in the 2 groups: 139 patients (30.8 percent) in the early group and 141 patients (31.5 percent) in the late group died. Two-year mortality was 51.0 percent in the early group and 53.7 percent in the late group.

For the 622 patients receiving tracheostomies, procedure-related complications were reported for a total of 39 patients (6.3 percent): twenty-three (5.5 percent) of 418 patients in the early group and 16 (7.8 percent) of 204 patients in the late group. The most frequent complication was bleeding sufficient to require intravenous fluids or another intervention.

For the 315 survivors of critical care in the early group and the 312 survivors in the late group, the median (midpoint) duration of critical care admission was 13.0 days in the early group and 13.1 days in the late group. Median total hospital stay in those surviving to discharge (256 both groups) was 33 days in the early group and 34 days in the late group.

“The implications, for clinical practice and for patients, from this study are found from the results in the late group. Not only were there no statistically significant difference in mortality between the 2 groups but, through waiting, an invasive procedure was avoided in a third of patients. Avoiding this significant proportion of tracheostomies, a procedure associated with a 6.3 percent acute complication rate in this study (and 38 percent-39 percent overall complication rates in the other recent multicenter studies), did not appear to be associated with any significant increase in health care resource use, as measured by critical care unit or hospital stay. It would appear that delaying a tracheostomy until at least day 10 of a patient’s critical care unit stay is the best policy,” the authors write.

“Early tracheostomy should therefore be avoided unless tools to accurately predict the duration of mechanical ventilation on individual patients can be developed and validated.”

Editorial: When Should a Mechanically Ventilated Patient Undergo Tracheostomy?

In an accompanying editorial, Derek C. Angus, M.D., M.P.H., of the University of Pittsburgh School of Medicine (and Contributing Editor, JAMA), writes that the finding in this study that tracheostomy generally should be delayed until at least 10 days after initiating mechanical ventilation has potentially important implications.

“Thus, 2 large, multicenter European trials show very similar findings: a strategy to perform tracheostomy early (within the first week) offers no benefit over a wait-and-see strategy that delays tracheostomy until after 10 days of mechanical ventilation. However, the consistently poor ability of clinicians to predict in the first few days which patients would eventually require prolonged ventilation means the early strategy inadvertently leads to a large increase in the number of unnecessary tracheostomies.”

“Nevertheless, if clinicians were to uniformly adopt a wait-and-see strategy, the number of tracheostomies would decline. Given the significant difference in diagnosis related group (DRG) payments for patients who are mechanically ventilated with and without a tracheostomy, hospital reimbursement also would decline. How hospital profitability would be affected by such a significant change in practice is unclear.”

“In coming years, payment reforms that bundle hospital, physician, and postacute care for inpatient episodes may make this quandary less important. However, as long as hospitals are reimbursed using a DRG system, it would seem prudent to revise the reimbursement strategies for patients facing potentially prolonged mechanical ventilation to better align financial incentives with the best clinical evidence.”

Treatment With Antidepressant Results in Lower Rate of Mental Stress-Induced Cardiac Ischemia

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 21, 2013

Media Advisory: To contact Wei Jiang, M.D., call Rachel Harrison at 919-419-5069 or email rachel.harrison@duke.edu.


CHICAGO – Among patients with stable coronary heart disease and mental stress-induced myocardial ischemia (MSIMI), 6 weeks of treatment with the antidepressant escitalopram, compared with placebo, resulted in a lower rate of MSIMI, according to a study in the May 22/29 issue of JAMA.

“A robust body of evidence has identified emotional stress as a potential triggering factor in coronary heart disease (CHD) and other cardiovascular events,” according to background information in the article. “During the last 3 decades, the association of emotional distress and myocardial ischemic activity [insufficient blood flow to the heart muscle, often resulting in chest pain] in the laboratory has been well studied. In the laboratory setting, MSIMI occurs in up to 70 percent of patients with clinically stable CHD and is associated with increased risk of death and cardiovascular events.” Few studies have examined therapeutics that effectively modify MSIMI. Recent evidence suggests that selective serotonin reuptake inhibitors (SSRIs) may reduce mental stress-induced hemodynamic response, metabolic risk factors, and platelet activity.

Wei Jiang, M.D., of the Duke University Medical Center, Durham, N.C., and colleagues conducted a study to investigate whether SSRI treatment can improve MSIMI. The randomized trial included patients with clinically stable coronary heart disease and laboratory-diagnosed MSIMI. Enrollment occurred from July 2007 through August 2011 at a tertiary medical center. Eligible participants were randomized 1:1 to receive escitalopram or placebo over 6 weeks. A total of 56 patients in each group completed end point assessments. Occurrence of MSIMI was defined via various measures during 1 or more of 3 mental stressor tasks: mental arithmetic, mirror trace, and public speaking with anger recall.

The researchers found that at the end of 6 weeks, more patients taking escitalopram (34.2 percent) had absence of MSIMI during the 3 mental stressors compared with patients taking placebo (17.5 percent). Analysis showed that the escitalopram group had a significantly higher rate (2.6 times) of no MSIMI compared with the placebo group. Also, hemodynamic responses to mental stress were all lower in the escitalopram group, with differences in systolic blood pressure and heart rate between the groups significant.

In addition, the 6-week escitalopram intervention was associated with greater improvements in certain measures of psychological functioning, including state anxiety and positive affect, during mental stress.

Exercise capacity was not significantly altered at week 6 in participants receiving escitalopram vs. those receiving placebo.

“In summary, 6-week pharmacologic enhancement of serotonergic function superimposed on the best evidence-based management of CHD appeared to significantly improve MSIMI occurrence. These results support and extend previous findings suggesting that modifying central and peripheral serotonergic function could improve CHD symptoms and may have implications for understanding the pathways by which negative emotions affect cardiovascular prognosis,” the authors conclude.

Genetic Variation Among Patients With Pulmonary Fibrosis Associated With Improved Survival

EMBARGOED FOR EARLY RELEASE: 1:00 P.M. (CT) TUESDAY, MAY 21, 2013

Media Advisory: To contact corresponding author David A. Schwartz, M.D., call Mark Couch at 303-724-5377 or email Mark.Couch@ucdenver.edu.


CHICAGO – Variation in the gene MUC5B among patients with idiopathic pulmonary fibrosis was associated with improved survival, according to a study published online by JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society international conference.

“Idiopathic pulmonary fibrosis (IPF) is a chronic progressive disease with a median [midpoint] survival of 3 years,” according to background information in the article. The prognosis is variable; patients may remain stable for several years, slowly lose lung function, progress in an intermittent fashion, or experience precipitous acute exacerbations. “Current prediction models of mortality in IPF, which are based on clinical and physiological parameters, have modest value in predicting which patients will progress. In addition to the potential for improving prognostic models, identifying genetic and molecular features that are associated with IPF mortality may provide insight into the underlying mechanisms of disease and inform clinical trials.”

Anna L. Peljto, Dr.P.H., of the University of Colorado Denver, and colleagues conducted a study to determine whether the variation (rs35705950) of the gene MUC5B, previously reported to be associated with the development of pulmonary fibrosis, is associated with survival among patients with IPF. The study included two independent cohorts of patients with IPF: the INSPIRE cohort, consisting of patients enrolled in the interferon-γ1b trial (n=438; December 2003 – May 2009; 81 centers in 7 European countries, the United States, and Canada), and the Chicago cohort, consisting of IPF participants recruited from the Interstitial Lung Disease Clinic at the University of Chicago (n = 148; 2007-2010). The INSPIRE cohort was used to model the association of MUC5B genotype with survival. The Chicago cohort was used for replication of findings.

The median follow-up period was 1.6 years for INSPIRE and 2.1 years for Chicago. During follow-up, there were 73 deaths among the INSPIRE cohort patients and 64 deaths among the Chicago cohort patients. Analysis indicated that the unadjusted 2-year cumulative incidence of death was lower among patients carrying 1 or more copies of the IPF risk allele (an alternative form of a gene) (T) in both the INSPIRE cohort and the Chicago cohort.

According to the authors, “The addition of the MUC5B genotype to the survival models significantly improved the predictive accuracy of the model in both the INSPIRE cohort and the Chicago cohort.”

“These findings suggest that the common polymorphism in the promoter of MUC5B (rs35705950), previously reported to be strongly associated with the development of familial interstitial pneumonia and idiopathic pulmonary fibrosis, is significantly associated with improved survival in IPF. These findings are consistent with a previous report of an association between the MUC5B variant and less severe pathological changes in familial interstitial pneumonia, as well as another report of slower decline in forced vital capacity for patients with IPF. This study is, to our knowledge, the first to demonstrate that a genetic variant is associated with survival in IPF.”

“Further research is necessary to refine the risk estimates and to determine the clinical implications of these findings,” the researchers conclude.

Shorter Duration Steroid Therapy May Offer Similar Effectiveness In Reducing COPD Exacerbations

EMBARGOED FOR EARLY RELEASE: 1:00 P.M. (CT) TUESDAY, MAY 21, 2013

Media Advisory: To contact Jorg D. Leuppi, M.D., Ph.D., email joerg.leuppi@ksli.ch. To contact editorial co-author Don D. Sin, M.D., call Justin Karasick at 604-806-8460 or email jkarasick@providencehealth.bc.ca.


CHICAGO – Among patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) requiring hospital admission, a 5-day glucocorticoid treatment course was non-inferior (not worse than) to a 14-day course with regard to re-exacerbation during 6 months of follow-up, according to a study published online by JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society international conference. The authors write that these findings support a shorter-course glucocorticoid treatment regimen, which would reduce glucocorticoid exposure and the risk of possible adverse effects.

“Acute exacerbations of COPD are a risk factor for disease deterioration, and patients with frequent exacerbations have an increased mortality,” according to background information in the article. “International guidelines advocate a 7- to 14-day course of systemic glucocorticoid therapy in acute exacerbations of COPD. However, the optimal dose and duration of therapy are unknown. … Given the adverse effects of glucocorticoids and the potentially large number of exacerbations occurring in patients with COPD, glucocorticoid exposure should be minimized.”

Jorg D. Leuppi, M.D., Ph.D., of the University Hospital of Basel, Switzerland, and colleagues conducted a study to examine whether a short-term (5 days) systemic glucocorticoid treatment in patients with COPD exacerbation is noninferior to conventional (14 days) treatment with respect to clinical outcome and whether it decreases the exposure to steroids. The randomized trial (REDUCE) was conducted in 5 Swiss teaching hospitals, enrolling 314 patients presenting to the emergency department with acute COPD exacerbation, past or present smokers without a history of asthma, from March 2006 through February 2011. Patients received treatment with 40 mg of prednisone daily for either 5 or 14 days in a placebo-controlled fashion. The predefined noninferiority criterion was an absolute increase in exacerbations of at most 15 percent. The primary measured outcome was time to next exacerbation within 180 days.

Of the 314 randomized patients, 289 (92 percent) of whom were admitted to the hospital, 311 were included in the intention-to-treat analysis and 296 in the per-protocol analysis. A total of 56 patients (35.9 percent) reached the primary end point of COPD exacerbation in the short-term treatment group compared with 57 patients (36.8 percent) in the conventional treatment group. Time to re-exacerbation did not differ between groups.

Among patients who experienced a re-exacerbation during follow-up, the median (midpoint) time to event was 43.5 days in the short-term group and 29 days in the conventional treatment group. Estimates of re-exacerbation rates were 37.2 percent in the short-term and 38.4 percent in the conventional treatment group.

“There was no difference between groups in time to death, the combined end point of exacerbation, death, or both and recovery of lung function. In the conventional group, mean (average) cumulative prednisone dose was significantly higher (793 mg vs. 379 mg), but treatment-associated adverse reactions, including hyperglycemia and hypertension, did not occur more frequently,” the authors write.

During hospital stay, there was no increase in the requirement for mechanical ventilation with the short-term treatment regimen.

“There was no significant difference in recovery of lung function and disease-related symptoms, but the shorter course resulted in a significantly reduced glucocorticoid exposure,” the researchers write. “These findings support the use of a 5-day glucocorticoid treatment in acute exacerbations of COPD.”

Editorial: Steroids for Treatment of COPD Exacerbations – Less Is Clearly More

Don D. Sin, M.D., and Hye Yun Park, M.D., Ph.D., of the University of British Columbia James Hogg Research Centre and the Institute for Heart and Lung Health, St. Paul’s Hospital, Vancouver, British Columbia, Canada, write in an accompanying editorial that “the clinical implications of this study are clear.”

“Most patients with acute COPD exacerbations can be treated with a 5-day course of prednisone or equivalent (40 mg daily). Furthermore, this regimen can be applied across all GOLD (Global Initiative for Chronic Obstructive Lung Disease) categories of disease severity. This is welcome news for patients with COPD who experience multiple exacerbations annually and are exposed to repeated courses of systemic corticosteroids. These findings will enable clinicians to minimize steroid exposure and reduce the risk of steroid-related toxicity in these patients.”

Providing Intravenous Nutrition Within 24 Hours For Certain Critically Ill Patients Does Not Appear to Improve Survival or Reduce ICU Length of Stay

EMBARGOED FOR EARLY RELEASE: 1:00 P.M. (CT) MONDAY, MAY 20, 2013

Media Advisory: To contact Gordon S. Doig, Ph.D., email gdoig@med.usyd.edu.au. To contact editorial co-author Juan B. Ochoa Gautier, M.D., call Rick Pietzak at 412-864-4151 or email pietzakr@upmc.edu.


CHICAGO – The early (within 24 hours of intensive care unit [ICU] admission) provision of intravenous nutrition among critically ill patients with contraindications (a condition that makes a particular procedure potentially inadvisable) to early use of enteral nutrition (such as through a feeding tube) did not result in significant differences in 60 day mortality or shorter ICU or hospital length of stay, compared with standard care, according to a study in the May 22/29 issue of JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society international conference. The intervention did result in a significant reduction in days of invasive mechanical ventilation.

“Parenteral nutrition [PN; intravenous administration of nutritional support] has been in common use since the 1960s and is accepted as the standard of care for patients with chronic nonfunctioning gastrointestinal tracts,” according to background information in the article. In critical illness, controversy surrounds the appropriate use of parenteral nutrition. “Systematic reviews suggest adult patients in ICUs with relative contraindications to early enteral nutrition [EN; feeding through the gastrointestinal tract, such as with the use of a feeding tube] may benefit from PN provided within 24 hours of ICU admission.”

Gordon S. Doig, Ph.D., of the University of Sydney, Australia, and colleagues conducted a multicenter clinical trial to assess the effects of providing parenteral nutrition within 24 hours of ICU admission to adult critically ill patients who would not otherwise receive nutrition therapy because of short-term relative contraindications to enteral nutrition. The randomized trial was conducted between October 2006 and June 2011 in ICUs of 31 community and tertiary hospitals in Australia and New Zealand. Participants were critically ill adults who were expected to remain in the ICU longer than 2 days.

A total of 1,372 patients were randomized (686 to standard care, 686 to early PN). Of 682 patients receiving standard care, 199 patients (29.2 percent) initially began EN, 186 patients (27.3 percent) initially began PN, and 278 patients (40.8 percent) remained unfed. Time to EN or PN in patients receiving standard care was 2.8 days. Patients receiving early PN began PN an average of 44 minutes after enrollment in the trial.

The researchers found that day-60 mortality did not differ significantly between groups (22.8 percent for standard care vs. 21.5 percent for early PN). There were also no significant differences between groups in rates of new infection. Standard care patients experienced significantly greater muscle wasting and significantly greater fat loss over the duration of their ICU stay.

Early PN patients rated day-60 quality of life statistically, but not clinically meaningfully, higher. Early PN patients required fewer days of invasive ventilation, but this did not result in a statistically significant reduction in ICU or hospital length of stay.

No harm was associated with the use of early parenteral nutrition in this trial.

Editorial: Early Nutrition in Critically III Patients – Feed Carefully and in Moderation

“The findings reported by Doig et al add important knowledge to the ongoing debate about when, how much, and through what route critically ill patients should be fed,” write Juan B. Ochoa Gautier, M.D., of the University of Pittsburgh, and Flavia R. Machado, M.D., Ph.D., of the Federal University of Sao Paulo, Brazil, in an accompanying editorial.

“This article joins several articles that suggest either benefit or harm from supplemental parenteral nutrition or whether ‘trophic feeding’ is ‘just as good’ as meeting nutritional goals in medical patients in the ICU during the first 7 days of their hospitalization. A significant amount of additional work is required to determine how to best deliver nutrition interventions in the ICU. It is essential (and indeed ethically imperative) for investigators at the forefront of this debate to be circumspect in their conclusions and clinical recommendations, to avoid their findings being misinterpreted and creating more harm than good. For now clinicians should attempt to optimize oral/enteral nutrition, avoid forced starvation if at all possible, and judiciously use supplemental parenteral nutrition.”

Association Suggested Between In-Hospital Cardiac Arrest Survival Rates, Prevention of Cardiac Arrests

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, MAY 20, 2013

JAMA Internal Medicine Study Highlights


CHICAGO – Hospitals with higher rates of survival among patients who experience in-hospital cardiac arrest also appear to have a lower incidence of in-hospital cardiac arrest, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

Lena M. Chen, M.D., M.S., of the University of Michigan, Ann Arbor, and colleagues identified 102,153 cases of in-hospital cardiac arrest at 358 hospitals between January 2000 and November 2009.

 

The median (midpoint) hospital cardiac arrest incidence rate was 4.02 per 1,000 admissions, and the median hospital case-survival rate was 18.8 percent. In crude statistical analysis, hospitals with higher case-survival rates also had lower cardiac arrest incidence, according to the results.

 

“Hospitals that excelled at preventing cardiac arrests also had higher survival rates for cardiac arrest cases, and this correlation persisted after adjustment for patient case mix. We found evidence that certain hospital factors, in part, mediated this relationship, but only one of the factors we examined – a hospital’s nurse-to-bed ratio – is potentially quickly modifiable,” the study concludes.

Music Therapy Appears to Help Reduce Anxiety, Use of Sedatives For Patients Receiving Ventilator Support

EMBARGOED FOR EARLY RELEASE: 1:00 P.M. (CT) MONDAY, MAY 20, 2013

Media Advisory: To contact Linda L. Chlan, Ph.D., R.N., call Kathryn Kelley at 614-688-1062 or email kelley.81@osu.edu. To contact editorial co-author Elie Azoulay, M.D., Ph.D., email elie.azoulay@sls.aphp.fr.


CHICAGO – Among intensive care unit patients receiving acute ventilatory support for respiratory failure, use of patient-preferred music resulted in greater reduction in anxiety and sedation frequency and intensity compared with usual care, according to a study published online by JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society international conference.

“Critically ill mechanically ventilated patients receive intravenous sedative and analgesic medications to reduce anxiety and promote comfort and ventilator synchrony,” according to background information in the article. These potent medications are often administered at high doses for prolonged periods and are associated with various adverse effects. “Mechanically ventilated patients have little control over pharmacological interventions to relieve anxiety; dosing and frequency of sedative and analgesic medications are controlled by intensive care unit (ICU) clinicians. Interventions are needed that reduce anxiety, actively involve patients, and minimize the use of sedative medications.” The authors note that “listening to preferred, relaxing music has reduced anxiety in mechanically ventilated patients in limited trials. It is not known if music can reduce anxiety throughout the course of ventilatory support, or reduce exposure to sedative medications.”

Linda L. Chlan, Ph.D., R.N., of Ohio State University, Columbus, and colleagues conducted a study to evaluate if a patient-directed music (PDM) intervention could reduce anxiety and sedative exposure in ICU patients receiving mechanical ventilation. The clinical trial included 373 patients from 12 ICUs at 5 hospitals in the Minneapolis-St. Paul area receiving acute mechanical ventilatory support for respiratory failure between September 2006 and March 2011. Of the patients included in the study, 86 percent were white, 52 percent were female, and the average age was 59 years. Patients were randomized to self-initiated PDM (n=126) with preferred selections tailored by a music therapist whenever desired while receiving ventilatory support; self-initiated use of noise-canceling headphones (NCH; n = 122); or usual care (n = 125). The main outcomes examined were daily assessments of anxiety (on a 100-mm visual analog scale) and 2 aggregate measures of sedative exposure (intensity and frequency).

The PDM patients listened to music for an average of 80 minutes/day; the NCH patients wore the noise-abating units for an average of 34.0 minutes/day. Analysis showed that patients in the PDM group had an anxiety score that was 19.5 points lower than patients in the usual care group.

For an average patient on the fifth study day (the average time patients were enrolled), a usual care patient received 5 doses of any 1 of the 8 study-defined sedative medications. An equivalent PDM patient received 3 doses of sedative medications on the fifth day, a relative reduction of 38 percent. By the end of the fifth day, a PDM patient had a relative reduction of 36 percent in their sedation intensity score and 36.5 percent in their anxiety score.

PDM did not result in greater reduction in anxiety or sedation intensity compared with NCH.

“Music provides patients with a comforting and familiar stimulus and the PDM intervention empowers patients in their own anxiety management; it is an inexpensive, easily implemented nonpharmacological intervention that can reduce anxiety, reduce sedative medication exposure, and potentially associated adverse effects. The PDM patients received less frequent and less intense sedative regimens while reporting decreased anxiety levels,” the authors write.

Editorial: Music Therapy for Reducing Anxiety in Critically Ill Patients

In an accompanying editorial, Elie Azoulay, M.D., Ph.D., of the Universite Paris-Diderot, Sorbonne Paris-Cite, and colleagues comment on the findings of this study.

“Reducing anxiety and amount of sedation in mechanically ventilated patients is of the utmost importance, particularly because the result may be a decrease in the post-ICU burden, which weighs heavily on many patients, as well as numerous complications related to sedation. The trial by Chlan et al provides preliminary data that create new possibilities for improving the well-being of ICU patients. Further studies are needed to better understand how music therapy might improve the ICU experience for critically ill patients.”

Two Radiotherapy Treatments Show Similar Morbidity, Cancer Control After Prostatectomy

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, MAY 20, 2013

Media Advisory: To contact corresponding author Ronald C. Chen, M.D., M.P.H., call William Davis at 919-966-5906 or email wishda@email.unc.edu.

JAMA Internal Medicine Study Highlights


CHICAGO – Use of the newer, more expensive intensity-modulated radiotherapy (IMRT) and use of the older conformal radiotherapy (CRT) after surgical removal of all or part of the prostate gland were associated with similar morbidity and cancer control outcomes, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

Gregg H. Goldin, M.D., of the University of North Carolina at Chapel Hill, and colleagues analyzed data from the Surveillance, Epidemiology and End Results-Medicare-linked database to identify patients who received IMRT or CRT. The study included the outcomes of 457 IMRT and 557 CRT patients who received radiotherapy between 2002 and 2007.

 

The use of IMRT increased from zero in 2000 to 82.1 percent in 2009. Men who received IMRT vs. CRT showed no significant difference in rates of long-term gastrointestinal morbidity, urinary nonincontinent morbidity, urinary incontinence or erectile dysfunction. There also appeared to be no difference in subsequent treatment for recurrent disease, according to the study results.

 

“Our results provide new and important information to patients, physicians, and other decision makers on the currently available evidence regarding the outcomes of different postprostatectomy radiation techniques. The potential clinical benefit of IMRT compared with CRT in this setting is unclear,” the study concludes.

JAMA Pediatrics Study Highlights


A study by Alexandra L. C. Martiniuk, M.Sc, Ph.D., of The George Institute for Global Health, Sydney, Australia, and colleagues suggests less sleep per night is associated with a significant increase in the risk for motor vehicle crashes for young drivers. (Online First)

 

Questionnaire responses were analyzed from 19,327 newly licensed drivers from 17 to 24 years old who held a first-stage provisional license between June 2003 and December 2004. Researchers also analyzed  licensing and police-reported crash data, with an average of 2 years of follow up.

 

On average, individuals who reported sleeping 6 or fewer hours per night had an increased risk for crash compared with those who reported sleeping more than 6 hours. Less weekend sleep was significantly associated with an increased risk for run-off-road crashes. Crashes for individuals who had less sleep per night (on average and on weekends) were significantly more likely to occur between 8 p.m. and 6 a.m.

 

“This provides rationale for governments and health care providers to address sleep-related crashes among young drivers,” the study concludes.

Bronchodilators Appear Associated with Increased Risk of Cardiovascular Events

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, MAY 20, 2013

Media Advisory: To contact author Andrea Gershon, M.D., M.S., call Deborah Creatura at 416-480-4780 or email Deborah.creatura@ices.on.ca. To contact invited commentary author Prescott G. Woodruff, M.D., M.P.H., call Elizabeth Fernandez at 415-514-1592 or email Elizabeth.Fernandez@ucsf.edu.


CHICAGO – A study of older patients with chronic obstructive pulmonary disease (COPD) suggests that new use of the long-acting bronchodilators β-agonists and anticholinergics was associated with similar increased risks of cardiovascular events, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

COPD affects more than 1 in 4 Americans older than 35 years of age and is the third leading cause of death in the United States. Medications are a mainstay of management of the disease. While there is little controversy about the effectiveness of long-acting β-agonists (LABAs) and long-acting anticholinergics (LAAs), their cardiovascular safety remains a matter of debate, according to the study background.

 

Andrea Gershon, M.D., M.S., of the Institute for Clinical Evaluative Sciences, Ontario, Canada, and colleagues conducted a nested case control analysis of a retrospective cohort study and compared the risk of cardiovascular events between patients newly prescribed the inhaled long-acting medications.

 

The study used health care databases from Ontario and included all individuals 66 years or older with a diagnosis of COPD who were treated from September 2003 through March 2009.

 

Of 191,005 eligible patients, 53,532 (28 percent) had a hospitalization or an emergency department visit for a cardiovascular event. According to the results, newly prescribed long-acting inhaled bronchodilators β-agonists and anticholinergics were associated with higher risk of a cardiovascular event compared with nonuse of those medications (respective adjusted odds ratios, 1.31 and 1.14). The results also indicate there was no significant difference in events between the two medications.

 

“Among older individuals with COPD, new use of long-acting β-agonists and anticholinergics is associated with similar increased risks of cardiovascular events. Close monitoring of COPD patients requiring long-acting bronchodilators is needed regardless of drug class,” the study concludes.

Invited Commentary: Double-edged Sword? Long-Acting Bronchodilators in Chronic Obstructive Pulmonary Disease

In an invited commentary, Prescott G. Woodruff, M.D., M.P.H., of the University of California, San Francisco, writes: “No pharmacotherapy has been shown to meaningfully alter the rate of progression of chronic obstructive pulmonary disease (COPD). However, inhaled long-acting bronchodilators are mainstays of treatment in moderate to severe COPD because they improve lung function, dyspnea [shortness of breath], rate of exacerbations and quality of life.”

 

“Ultimately, clinical trial data do not fully resolve the question of cardiovascular risks with LAMAs [muscarinic antagonists termed long-acting anticholinergics by Gershon et al] and LABAs [long-acting inhaled β-agonists] because some of the data are discordant and because clinical trials generally exclude patients at greatest risk for cardiovascular complications,” Woodruff continues.

 

“In conclusion, no single study will satisfactorily resolve the controversy, and at least three important questions cannot be addressed by this study. … Finally, although the authors recommend that ‘subjects should be monitored closely,’ a firm recommendation on what that monitoring should be cannot be made. Monitoring, of course, is the responsibility of an informed treating physician. The main contribution of this study is to highlight that responsibility,” Woodruff concludes.

Clinical Trial Finds Fluid And Sodium Restrictions Have No Effect On Weight Loss Or Clinical Stability Among Patients Hospitalized with Heart Failure

EMBARGOED FOR RELEASE: 3 P.M. (CT), MONDAY, MAY 20, 2013

Media Advisory: To contact corresponding author Luis Beck-da-Silva, M.D., Sc.D., email luisbeckdasilva@gmail.com.


CHICAGO – A clinical trial of 75 patients hospitalized with acute decompensated heart failure (ADHF) suggests that aggressive fluid and sodium restriction has no effect on weight loss or clinical stability at three days but was associated with an increase in perceived thirst, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

 

Sodium and fluid restrictions are nonpharmacologic measures widely used to treat ADHF despite a lack of clear evidence of their therapeutic effect, the authors write in the study background.

 

“We conclude that sodium and water restriction in patients admitted for ADHF are unnecessary,” Graziella Badin Aliti, R.N., Sc.D., of the Hospital de Clìnicas de Porto Alegre, Brazil, and colleagues comment in the study.

 

The clinical trial compared the effects of a fluid-restricted (maximum fluid intake, 800 mL/d) and sodium-restricted (maximum dietary intake, 800 mg/d) diet in an intervention group (IG) versus a diet with no such restrictions in a control group (CG). The main outcomes the authors measured were weight loss and clinical stability at the three-day assessment, as well as daily perception of thirst and readmissions within 30 days.

 

According to the results, weight loss was similar in both groups (between-group difference in variation of 0.25kg) as well as the change in clinical congestion score (between-group difference in variation of 0.59 points) at three days. Thirst was increased in the IG, but there were no significant between-group differences in the readmission rate at 30 days, the results indicate.

 

“In summary, this RCT contributes to the field of HF [heart failure] research by showing that, in patients with ADHF, aggressive fluid and sodium restriction had no effect on weight loss or clinical stability compared with a diet with liberal fluid and sodium intakes. Furthermore, this aggressive intervention was associated with significantly higher rates of perceived thirst,” the study concludes.

Study Examines Relationship Between Hemispheric Dominance and Cell Phone Use

EMBARGOED FOR RELEASE: 3 P.M. (CT), THURSDAY, MAY 16, 2013

Media Advisory: To contact study author Michael D. Seidman, M.D., call Krista Hopson at 313-874-7207 or email Krista.Hopson@hfhs.org.

JAMA Otolaryngology-Head & Neck Surgery Study Highlights


A study by Michael D. Seidman, M.D., of the Henry Ford Health System, West Bloomfield, Michigan, and colleagues examined if an association exists between sideness of cell phone use and auditory hemispheric dominance (AHD) or language hemispheric dominance (LHD).

 

An Internet survey was randomly e-mailed to 5,000 individuals, 717 surveys were completed. Sample questions surveyed which hand was used for writing, whether the right or left ear was used for phone conversations, as well as whether a brain tumor was present.

 

According to the results, ninety percent of the respondents were right handed, and 9 percent were left handed. Sixty-eight percent of the right-handed people used the cell phone in their right ear, 25 percent in the left ear, and 7 percent had no preference. Seventy-two of the left-handed respondents used the cell phone in their left ear, 23 percent used their right ear, and 5 percent had no preference.

 

“An association exists between hand dominance laterality of cell phone use (73 percent) and our ability to predict hemispheric dominance. Most right-handed people have left-brain LHD and use their cell phone in their right ear. Similarly, most left-handed people use their cell phone in their left ear,” the study concludes.

Research Letter Suggests Twitter May Serve as a Good Forum For Communicating Information About Acne

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 15, 2013

Media Advisory: To contact study author Kamal Jethwani, M.D., M.P.H., call Gina Cells at 781-799-3137 or email GinaCella@comcast.net.

JAMA Dermatology Study Highlights


A research letter by Kamal Jethwani, M.D., M.P.H., of the Center for Connected Health, Boston, and colleagues suggests that clinicians can learn about the perceptions and misconceptions of diseases like acne via Twitter, and communicate reliable medical information on the popular social media platform.

 

Using a form of real-time data capture through the use of the Twitter Streaming Application Programming Interface (API), researchers collected all tweets that contained one or more of 5 keywords: pimple, pimples, zit, zits and acne for a 2-week period in June 2012. High-impact tweets, defined as tweets with one or more retweets, were the only tweets examined. High-impact tweets were frequency weighted by retweet count and categorized by content into 4 main categories: personal, celebrity, education, and irrelevant/excluded. The education category was subdivided into: disease question, disease information, treatment question, treatment information (branded), treatment information (non-branded), and treatment information (ambiguous).

 

There were a total of 8,192 English high-impact tweets of a total of 392,617 tweets collected. Personal tweets about acne were the most common type of high-impact tweets (43.1 percent), followed by tweets about celebrities (20.4 percent) and then education-related tweets (27.1 percent); 9.4 percent of tweets were excluded. By education subcategory, 16.9 percent and 8.9 percent of all high-impact tweets were about disease information and treatment information, respectively. Two-thirds of disease question tweets asserted in some way that stress causes pimples, and 9 percent of retweets commented that makeup causes pimples, the study finds.

 

“Twitter is emerging as a popular forum where people exchange health information. Health providers can not only learn about the perceptions and misperceptions of diseases like acne, but they might also communicate reliable medical information,” the authors conclude.

Study Suggests Cuataneous Squamous Cell Carcinoma Carries Risk of Metastasis and Death

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 15, 2013

Media Advisory: To contact study author Chrysalyne D. Schmults, M.D., M.S.C.E., call Tom Langford at 617-534-1605 or email tlangford@partners.org.

JAMA Dermatology Study Highlights


A study by Chrysalyne D. Schmults, M.D., M.S.C.E., of Brigham and Women’s Hospital, Boston, and colleagues suggests cutaneous squamous cell carcinoma (CSCC) carries a low but significant risk of metastasis and death.

 

The ten-year retrospective cohort study was conducted at an academic medical center in Boston, and included 985 patients with 1,832 tumors. Main measures of the study were subhazard ratios for local recurrence, nodal metastasis, disease-specific death, and all-cause death adjusted for presence of known prognostic risk factors. The median follow-up was 50 months.

 

Local recurrence occurred in 45 patients (4.6 percent) during the study period; 36 (3.7 percent) developed nodal metastases; and 21 (2.1 percent) died of CSCC. Independent predictors for nodal metastasis and disease-specific death were tumor diameter of at least 2 centimeters, poor differentiation, invasion beyond fat, and ear or temple location. Perineural invasion, cancer spreading to the space surround a nerve, was also associated with disease-specific death, as was anogenital location. Overall death was associated with poor differentiation and invasion beyond fat, the study finds.

 

“Tumor diameter of at least 2 centimeters, invasion beyond fat, poor cellular differentiation, perineural invasion, and ear, temple, or anogenital location were risk factors for poor outcomes. These 5 risk factors may be among the most significant drivers of CSCC outcomes, but further studies are needed to replicate our findings” the authors conclude.

Study of Traumatic Brain Injury, Suicide Risk in Deployed Military Personnel

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 15, 2013

Media Advisory: To contact study author Craig J. Bryan, Psy.D., A.B.P.P., email craig.bryan@utah.edu.

JAMA Psychiatry Study Highlights


A study by Craig J. Bryan, Psy.D., A.B.P.P., of the National Center for Veterans Studies, Salt Lake City, Utah, suggests that suicide risk is higher among military personnel with more lifetime traumatic brain injuries (TBIs).

 

Patients included 161 military personnel referred for evaluation and treatment of suspected head injury at a military hospital’s TBI clinic in Iraq. Patients completed standardized self-report measures of depression, posttraumatic stress disorder, suicidal thoughts and behaviors; as well as a clinical interview and physical examination.

 

Depression, PTSD and TBI symptom severity significantly increased with the number of TBIs. There also was an increased incidence of lifetime suicidal thoughts or behaviors (no TBIs, 0 percent; single TBI, 6.9 percent, and multiple TBIs 21.7 percent) and suicidal ideation within the past year.

 

“Results suggest that multiple TBIs, which are common among military personnel, may contribute to increased risk for suicide,” the study concludes.

Surgical Residents Disapprove of 2011 ACGME Duty Hour Regulations, Survey Finds

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 15, 2013

Media Advisory: To contact study author Brian C. Drolet, M.D., call Ellen Slingsby at 401-444-6424 or email eslingsby@lifespan.org.

JAMA Surgery Study Highlights


In a study by Brian C. Drolet, M.D., of the Rhode Island Hospital, Providence, and colleagues, the majority of surgical residents who were surveyed reported that they disapprove of the 2011 Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirements (65.9 percent).

 

A total of 1,013 residents in general surgery and surgical specialties at 123 ACGME-accredited teaching hospitals in the United States and U.S. territories answered a 20-question electronic survey administered six months after implementation of the 2011 ACGME regulations. Residents’ perceptions of changes in education, patient care, and quality of life after institution of 2011 ACGME duty hour regulations and their compliance with these rules were assessed.

 

Most surgical residents indicated that education (55.1 percent), preparation for senior roles (68.4 percent), and work schedules (50.7 percent) were worse after implantation of the 2011 regulations. They reported no change in supervision (80.8 percent), safety of patient care (53.5 percent) or amount of rest (57.8 percent). A majority report increased handoffs (78.2 percent) and a shift of junior-level responsibilities to senior residents (68.7 percent), the study finds.

 

“The proposed benefits of the increased duty hour restrictions—improved education, patient care, and quality of life—have ostensibly not borne out in surgical training. It may be difficult for residents, particularly in surgical fields, to learn and care for patients under the 2011 ACGME regulations,” the authors conclude.

No Significant Change Seen in Overall Smokeless Tobacco Use Among U.S. Youths

Tobacco use remains the leading preventable cause of death and disease in the United States. Declines in smoking among youths were observed from the late 1990s. “However, limited information exists on trends in smokeless tobacco use among U.S. youths,” writes Israel T. Agaku, D.M.D., M.P.H., of the Harvard School of Public Health, Boston, and colleagues.

As reported in a Research Letter, the authors analyzed recent trends in prevalence of smokeless tobacco use among youths using the 2000-2011 National Youth Tobacco Survey, a biennial national cross-sectional survey of U.S. middle school and high school students. Samples during 2000 through 2011 ranged from 35,828 students in 324 schools in 2000 to 18,866 students in 178 schools in 2011. Current smokeless tobacco use was defined as use of snuff, chewing, or dipping tobacco for 1 or more days within the past 30 days.

The researchers found that no significant change in overall smokeless tobacco prevalence occurred between 2000 (5.3 percent) and 2011 (5.2 percent). Downward trends were observed in the age groups of 9 to 11 and 12 to 14 years. Prevalence increased in the age group of 15 to 17 years.

“The prevalence of smokeless tobacco use among U.S. youths did not change between 2000 and 2011 and remained generally low. However, subgroup differences were observed. The use of modified traditional smokeless tobacco products, such as moist snuff, coupled with lower taxes on smokeless tobacco products (vs. cigarettes) may have contributed to the stable prevalence of smokeless tobacco (vs. the declining trend for cigarettes),” they write. “… these findings emphasize the need for evidence-based interventions to reduce smokeless tobacco use among youths.”

Viewpoints in This Issue of JAMA

Two counter Viewpoints address the question: Should religious-based organizations be required to provide contraceptive coverage?

Contraception Is a Fundamental Primary Care Service

The Affordable Care Act (ACA) requires health care plans after August 1, 2012, to cover preventive health services recommended by the Institute of Medicine and endorsed by the Department of Health and Human Services. “Some religious organizations and private employers, however, have demanded exemption from providing contraception, arguing that it violates their religious beliefs,” writes Dana R. Gossett, M.D., M.S.C.I., of the Northwestern University Feinberg School of Medicine, Chicago, and colleagues. “We believe that allowing such an exception is at odds with evidence-based preventive care, inconsistent with actual patterns of contraceptive use among women who are religious, and a sectarian incursion into private health care decisions that is without parallel in the U.S. health care system.”

“Women whose health coverage is provided by a religious organization would face access barriers and additional costs compared with women whose coverage is provided by secular organizations, despite similar rates of demand and use. Lowering economic barriers to the most effective forms of birth control, long-acting reversible contraception, has been demonstrated to improve utilization and decrease rates of abortion and teenage pregnancy.”

“Both men and women engage in sexual activity, but women disproportionately bear the consequences of sexual activity in their risk of pregnancy and its attendant health outcomes. The strategy for managing the health of the nation cannot systematically discriminate against any one group of citizens. It is in the interest of the medical community and society at large to prevent such discrimination.”

Contraceptives and the Law – A View From a Catholic Medical Institution

“As faculty members at the Creighton University School of Medicine—one of 4 Catholic medical schools in the United States—we question whether the public health benefits of mandated contraception coverage in the United States are so substantial that individuals and institutions should be forced to take actions that violate their collective moral conscience, thereby doing unnecessary harm to the principle of religious freedom,” writes Eric A. Zimmer, S.J., Ph.D., of the Creighton University School of Medicine and Creighton Center for Health Policy Ethics, Omaha, Neb., and colleagues.

“What is now at issue is whether the U.S. government, in policies that promote dissemination of cost-free birth control as a social imperative, has properly weighed the benefits vs. the harms created by this policy. The government should always strive to respect religious freedom, including that within institutions. If this right is to be restricted for the sake of a public health need, rigorous standards should be applied to validate this need and to weigh the relative value of preventive health care interventions proposed.”

“A careful analysis is required that attempts to balance the value of regulation of reproductive activity against the legal, medical, and ethical implications of this mandate. A thorough evaluation will take time, but the immediate issue to be decided is whether there is such a pressing public health need that the U.S. government should use its ultimate power to overcome the religious objections of employers and force them to provide services inconsistent with their beliefs and value systems.”

Study Evaluates Long-Term Effectiveness of Surgery for Pelvic Organ Prolapse

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 14, 2013

Media Advisory: To contact Ingrid Nygaard, M.D., call Phil Sahm at 801-581-2517 or email phil.sahm@hsc.utah.edu. To contact editorial author Cheryl B. Iglesia, M.D., call Karen Mallet at 215-514-9751 or email km463@georgetown.edu.


CHICAGO – Results after seven years of follow-up suggest that women considering abdominal sacrocolpopexy (surgery for pelvic organ prolapse [POP]) should be counseled that this procedure effectively provides relief from POP symptoms; however, the anatomic support deteriorates over time; and that adding an anti-incontinence procedure decreases, but does not eliminate the risk of stress urinary incontinence, and mesh erosion can be a problem, according to a study in the May 15 issue of JAMA.

“Pelvic organ prolapse occurs when the uterus or vaginal walls bulge into or beyond the vaginal introitus [vaginal opening]. It is a common occurrence and 7 percent to 19 percent of women receive surgical repair,” according to background information in the article. More than 225,000 surgeries are performed annually in the United States for POP. Abdominal sacrocolpopexy is the most durable operation for advanced POP and serves as the criterion standard against which other operations are compared, but little is known about safety and long-term effectiveness.

Ingrid Nygaard, M.D., of the University of Utah School of Medicine, Salt Lake City, and colleagues conducted a study to describe anatomic and symptomatic outcomes up to 7 years after abdominal sacrocolpopexy and to determine whether these are affected by anti-incontinence surgery (Burch urethropexy). The study consisted of a long-term follow-up of the randomized, 2-year Colpopexy and Urinary Reduction Efforts (CARE) trial of women with stress continence who underwent abdominal sacrocolpopexy between 2002 and 2005 for symptomatic POP and also received either concomitant Burch urethropexy or no urethropexy. Ninety-two percent (215/233) of eligible 2-year CARE trial completers were enrolled in the extended CARE study; and 181 (84 percent) and 126 (59 percent) completed 5 and 7 years of follow-up, respectively. The median (midpoint) follow-up was 7 years.

Of 215 women enrolled in the extended CARE study, 104 had undergone abdominal sacrocolpopexy plus Burch urethropexy and 111 had undergone abdominal sacrocolpopexy alone. The researchers found that that POP and urinary incontinence (UI) treatment failure rates gradually increased during the follow-up period. By year 7, the estimated probabilities of POP treatment failure for the urethropexy group and the no urethropexy group, respectively, were 0.27 and 0.22 for anatomic failure; 0.29 and 0.24 for symptomatic failure; and 0.48 and 0.34 for a composite of both.

Overall for the duration of the study, the estimated probability of stress urinary incontinence (SUI) was 0.62 for the urethropexy and 0.77 for the no urethropexy group. The expected time to treatment failure for the SUI outcome in the urethropexy group vs. the no urethropexy group was 131.3 months vs. 40.2 months, respectively.

The probability of mesh erosion at 7 years was 10.5 percent.

“Three key points emerge from these data. First, as a criterion standard for the surgical treatment of POP, abdominal sacrocolpopexy is less effective than desired. … Second, surgical prevention of SUI at the time of abdominal POP surgery involves no clinically significant trade-offs identified to date. … In addition, we found that complications related to synthetic mesh continue to occur over time,” the authors write.

“We anticipate that continued research in mesh development will lead to new materials and applications with fewer adverse events, but our data highlight the importance of careful long-term evaluation of new devices. Comparative effectiveness trials with long-term follow-up of at least 5 years are needed to compare abdominal sacrocolpopexy that we described in this report with vaginal prolapse procedures that include and do not include mesh augmentation.”

“Abdominal sacrocolpopexy effectiveness should be balanced with long term risks of mesh or suture erosion.”

Editorial: Pelvic Organ Prolapse Surgery – Long-term Outcomes and Implications for Shared Decision Making

“This study has important clinical implications and calls into question the designation of the abdominal sacrocolpopexy as the criterion standard procedure for prolapse repair,” writes Cheryl B. Iglesia, M.D., of the Georgetown University School of Medicine, Washington, D.C., in an accompanying editorial.

“In this era of shared decision making, the next logical question is, ‘How do physicians advise patients who are contemplating pelvic reconstructive surgery for prolapse?’ Rates of prolapse and incontinence surgery are expected to increase substantially during the next 40 years as the population ages. Patients need to discuss with their physicians the available surgical and nonsurgical options for prolapse and incontinence, medical comorbidities, and review of available data. Surgeons and patients should also discuss prophylactic concomitant or staged surgery for stress incontinence at the time of prolapse repair. Timing of prolapse repair based on quality-of-life decisions should also be discussed preoperatively.”

Dual Chamber ICDs Show Higher Risk of Complications

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 14, 2013

Media Advisory: To contact Pamela N. Peterson, M.D., M.S.P.H., call Jenny Bertrand at 303-602-4924 or email Jennifer.bertrand@dhha.org.


CHICAGO – Even though patients receiving an implantable cardioverter-defibrillator (ICD) for primary prevention often receive a dual-chamber ICD, an analysis that included more than 32,000 patients receiving an ICD without indications for pacing finds that the use of a dual-chamber device compared with a single-chamber device was associated with a higher risk of device-related complications and similar 1-year mortality and hospitalization outcomes, according to a study in the May 15 issue of JAMA.

“The central decision regarding ICD therapy is whether to use a single- or dual-chamber device,” according to background information in the article. More complex dual-chamber devices may offer theoretical benefits beyond single-chamber devices for patients without an indication for pacing, but may also have greater risks. In a national sample, more than two-thirds of patients receiving an ICD received a dual-chamber device. “The outcomes of dual- vs. single-chamber devices are uncertain.”

Pamela N. Peterson, M.D., M.S.P.H., of the Denver Health Medical Center, and colleagues conducted a study to compare outcomes, including mortality, hospitalizations, and longer-term implant-related complications between single- and dual-chamber devices. The study included admissions in the National Cardiovascular Data Registry’s (NCDR) ICD registry from 2006-2009 that could be linked to Centers for Medicare & Medicaid Services fee-for-service Medicare claims data. Patients were included if they received an ICD for primary prevention and did not have a documented indication for pacing.

Among 32,034 patients, 12,246 (38 percent) received a single-chamber device and 19,788 (62 percent) received a dual-chamber device. After analysis of the data, the researchers found that rates of complications were lower for single-chamber devices (3.51 percent vs. 4.72 percent), but device type was not significantly associated with 1-year mortality (unadjusted rate, 9.85 percent vs. 9.77 percent), 1-year all-cause hospitalization (unadjusted rate, 43.86 percent vs. 44.83 percent), or hospitalization for heart failure (unadjusted rate, 14.73 percent vs. 15.38 percent).

The authors suggest that their study advances the understanding of the risks of dual-chamber devices. “Because implanting a dual-chamber ICD is a more complex and time-consuming procedure than implanting a single-chamber device, the possibility of device-related complications such as infection and lead displacement requiring device revision is likely to increase. Indeed, we observed a greater risk of complications among patients receiving dual-chamber devices.”

“Many patients receiving primary prevention ICDs receive dual-chamber devices. Dual-chamber devices do not appear to offer any clinical benefit over single-chamber devices with regard to death, all-cause readmission, or heart failure readmission in the year following implant. However, dual-chamber ICDs are associated with higher rates of complications. Therefore, among patients without clear pacing indications, the decision to implant a dual-chamber ICD for primary prevention should be considered carefully.”

Study Examines Use of Creative Arts Therapies Among Patients with Cancer

 

Creative arts therapies (CATs) can improve anxiety, depression, pain symptoms and quality of life among cancer patients, although the effect was reduced during follow-up in a study by Timothy W. Puetz, Ph.D., M.P.H., of the National Institutes of Health, Bethesda, Md., and colleagues.

 

Authors reviewed the available medical literature and included 27 studies involving 1,576 patients. Researchers found that during treatment, CAT significantly reduced anxiety, depression and pain, and increased quality of life. However, the effects were greatly diminished during follow-up, the study concludes.

 

“Future well-designed RCTs are needed to address the methodological heterogeneity found within this field of research,” according to the study.

JAMA Internal Medicine Study Highlights

Study Evaluates Calories, Fat, and Sodium Content in Restaurant Meals

 

A research letter by Mary R. L’Abbe, Ph.D., of the University of Toronto, Canada, and colleagues examined the nutritional profile of breakfast, lunch, and dinner meals from sit-down restaurants (SDR). (Online First)

 

A total of 3,507 different variations of 685 meals, as well as 156 desserts from 19 SDRs were included in the study. Nutrients evaluated included calories, fat, saturated fat, and sodium; excess consumption of these nutrients is associated with obesity, hypertension, heart disease, diabetes, and cancer. Nutrient values were calculated as a percentage of the daily value (%DV).

 

Researchers found on average, breakfast, lunch, and dinner meals contained 1,128 calories (56 percent of the average daily 2,000 calories recommendation), 151 percent of the amount of sodium an adult should consume in a single day (2,269 milligrams), 89 percent of the daily value for fat (58 grams), 83 percent of the daily value for saturated and trans fat (16 grams of saturated fat and 0.6 grams of trans fat), and 60 percent of the daily value for cholesterol (179 grams).

 

Overall, the results of this study demonstrate that calories, fat, saturated fat, and sodium levels are alarmingly high in breakfast, lunch, and dinner meals from multiple chain SDRs. Therefore, addressing the nutritional profile of restaurant meals should be a major public health priority,” the study concludes.

Study Finds Inconsistent and Slow Reduction in Sodium Levels in Processed and Restaurant’s Food

 

A study by Michael F. Jacobson, Ph.D., of the Center for Science in the Public Interest, Washington, D.C., and colleagues suggest voluntary reductions in sodium levels in processed and restaurant foods is inconsistent and slow. (Online First)

 

The study measured the sodium content in selected processed foods and fast-food restaurant foods in 2005, 2008, and 2011. Between 2005 and 2011, the sodium content in 402 processed foods declined by approximately 3.5 percent, while the sodium content in 78 fast-food restaurant products increased by 2.6 percent. Although some products showed decreases of at least 30 percent, a greater number of products showed increases of at least 30 percent. The predominant finding is the absence of any appreciable or statistically significant changes in sodium content during six years.

 

Stronger action (e.g. phased-in limits on sodium levels set by the federal government) is needed to lower sodium levels and reduce the prevalence of hypertension and cardiovascular disease,” the study concludes.

Study Updates Estimates, Trends for Childhood Exposure to Violence, Crime, Abuse

 

A study by David Finkelhor, Ph.D., of the University of New Hampshire, and colleagues updates estimates and trends for childhood exposure to a range of violence, crime and abuse victimizations. (Online First)

 

The study used the National Survey of Children’s Exposure to Violence, which was based on a national telephone survey conducted in 2011. The participants included 4,503 children and teenagers between the ages of one month to 17 years.

 

According to the results, 41.2 percent of children and youth experienced a physical assault in the last year; 10.1 percent experienced an assault-related injury; and 2 percent experienced sexual assault or sexual abuse in the last year, although the rate was 10.7 percent for girls ages 14 to 17 years. The results also indicate that 13.7 percent of the children and youth repeatedly experienced maltreatment by a caregiver, including 3.7 percent who experienced physical abuse.

 

“The variety and scope of children’s exposure to violence, crime, and abuse suggest the need for better and more comprehensive tools in clinical and research settings for identifying these experiences and their effects,” the study concludes.

Elective Cesarean Delivery Requested by Pregnant Women Requires Careful Consideration of Potential Benefits and Risks

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 7, 2013

Media Advisory:  To contact Jeffrey Ecker, M.D., call Susan McGreevey at 617-724-2764 or email: smcgreevey@partners.org

 

CHICAGO – A Clinical Crossroads review article in the May 8 issue of JAMA discusses the potential benefits and risks for pregnant women who request cesarean delivery without an indication of need rather than proceeding with a plan for vaginal delivery.

Jeffrey Ecker, M.D., from Massachusetts General Hospital, Boston, is the author of the article that examines this issue of cesarean delivery on maternal request (CDMR).   Dr. Ecker writes the term “refers to cesarean delivery performed without maternal or fetal indication; i.e., with no expectation of improving the physical health of the mother or neonate.”    Dr. Ecker notes that available data indicate that CDMR occurs in less than three percent of all deliveries in the United States.

“Reasons for considering CDMR include fear of specific elements of labor and concern for fetal or maternal morbidities attributable to vaginal delivery,” Dr. Ecker writes.   “Compared with a plan for vaginal delivery, CDMR may be associated with lower rates of hemorrhage, maternal incontinence, and rate but serious neonatal outcomes.  However, CDMR is associated with a higher risk of neonatal respiratory morbidity.”   And Dr. Ecker writes that repeated caesarean deliveries have higher rates of operative complications and placental abnormalities.

The article concludes: “There is no immediate expectation for CDMR to reduce the health risks of mothers or infants.   Accordingly, counseling and decisions regarding CDMR should be made after considering a woman’s full reproductive plans.”

Study Examines Patient Outcomes, Satisfaction, Recovery After Endoscopic Brow-Lift Surgery

 

A study by Neal D. Goldman, M.D., of The Goldman Center for Facial Plastic Surgery, North Carolina, and colleagues examines patient-reported outcomes, satisfaction, and recovery after endoscopic brow-lift (EBL) surgery to improve preoperative counseling. (Online First)

 

A total of 57 patients who had EBL with concurrent rhytidectomy participated in a retrospective telephone survey to assess cosmetic and functional outcomes using 47 questions evaluating outcomes, satisfaction, and recovery.

 

According to the study results, 53 patients (93 percent) reported the procedure was successful, and 55 patients (96 percent) would recommend undergoing this procedure. Patients who underwent rhytidectomy were significantly more likely to take weeks or longer to return to normal activities. No differences were noticed between rhytidectomy with EBL compared with EBL alone in analgesic use, edema, numbness, alopecia, and satisfaction.

 

“Endoscopic brow-lift is well tolerated and most patients are happy with the outcome. Relying on patient-reported information helps us to better understand the surgical experience and to improve preoperative counseling,” the study concludes.

Study Suggests Physical Barriers, Sunscreens Partially Prevent UV-B Effects

JAMA Dermatology Study Highlights

Study Suggests Physical Barriers, Sunscreens Partially Prevent UV-B Effects

 

A study by Cristina Carrera, M.D., of the Hospital Clínic de Barcelona, Spain, and colleagues suggests both physical barriers and sunscreens can partially prevent UV-B effects on nevi. (Online First)

 

The prospective study included 23 nevi from 20 patients attending a referral hospital. Half of each nevus was protected by either a physical barrier or a sunscreen. Lesions were completely irradiated by a single dose of UV-B. Outcomes were measured through vivo examinations before and 7 days after irradiation and histopatholoic-immunopathologic was evaluated after excision on the seventh day.

 

According to the study results, the most frequent clinical changes after UV radiation were pigmentation, scaling, and erythema; the most frequent dermoscopic changes were increased globules/dots, blurred network, regression, and dotted vessels. Both physical barrier-and sunscreen-protected areas showed some degree of these changes. The only difference between both barriers was more enhanced melanocytic activation and regression features in the sunscreen group. No phenotypic features were found to predict a specific UV-B response.

 

“Both physical barriers and sunscreens can partially prevent UV-B effects on nevi. Subclinical UV radiation effects, not always associated with visible changes, can develop even after protection. Sunscreens are not quite as effective as physical barriers in the prevention of inflammatory UV-B-induced effects,” the authors notes.

Research Letter Examines Effects of Chemical Sunscreen on UV Radiation in Melanocytic Nevi

 

In a research letter, Rainer Hofmann-Wellenhof, M.D., of the Medical University of Graz, Austria, and colleagues examined the effects of a chemical sunscreen on UV-Induced changes of different histological features in melanocytic nevi. (Online First)

 

Researchers selected 26 melanocytic nevi from 26 patients (12 male and 14 female, mean age, 31 years; median age, 31.5 years) in 2003. A sunscreen with sun protection factor (SPF) of 6.2 (containing UV-A and UV-B filter) was applied exactly to one-half of each nevus by using a tape to avoid contamination of the other half. Clinical and dermoscopic images were acquired using a digital camera equipped with a polarized dermatoscope at baseline (day 0) before sunscreen application and UV irradiation and at day 3 and day 7 when the nevus was excised.  

 

Dermoscopy at day 3 showed an increase of erythema and a more pronounced pigment network in the unprotected halves but without statistical differences compared with the protected halves. At day 7 researchers observed an increase of brown to black globuli, brown dots, bluish white veil, atypical network, and increased vessels in both protected and unprotected halves without statistical differences between the 2 halves. The HMB-45 stain resulted in significantly stronger staining in the unprotected halves compared with the protected ones, the study finds.

 

“In summary, we extended the dermoscopic findings observed by Carrera et al into the field of solar-simulated UV radiation, and we agree that not all UV-induced changes are confined to unprotected areas,” the authors notes.

Study Finds Increase in Fall-Related Traumatic Brain Injuries Among Elderly Men and Women

“Traumatic brain injury (TBI) is a major cause of hospitalization, disability, and death-worldwide, and among older adults, falling is the most common cause of TBI,” writes Niina Korhonen, B.M., of the Injury and Osteoporosis Research Center, Tampere, Finland, and colleagues in a Research Letter. The authors previously reported that the number and incidence of adults 80 years of age or older admitted to the hospital due to fall-induced TBI in Finland increased from 1970 through 1999. This analysis is a follow-up of this population through 2011.

The study included data from the Finnish National Hospital Discharge Register, a nationwide, computer-based register that provides data for severe injuries among the Finnish population. The researchers found that the total number of older Finnish adults with a fall-induced TBI increased considerably from 60 women and 25 men in 1970 to 1,205 women and 612 men in 2011. The age-adjusted incidence of TBI (per 100,000 persons) also showed an increase from 168.2 women in 1970 to 653.6 in 2011 (an increase of 289 percent) and from 174.6 to 724.0, respectively, in men (an increase of 315 percent).

“Our 40-year follow-up shows that the number and age-adjusted incidence of fall-induced TBI in Finnish men and women aged 80 years or older increased considerably between 1970 and 2011. Compared with the data in our previous study, the increase has continued since 1999,” the authors write. “Further studies are needed to better understand the reasons for the increase in fall-related TBI in older persons (aged >80 years) so that effective interventions for falls and injury prevention can be initiated.”

Viewpoints in This Issue of JAMA

Investments in Infrastructure for Diverse Research Resources and the Health of the Public

“Active surveillance of drugs and devices in the postmarket setting is an essential component of the lifecycle approach to drug evaluation. The U.S. Food and Drug Administration (FDA) Amendments Act of 2007 required the agency to develop ‘a postmarket risk identification and analysis system.’ In response, scientists from the FDA and investigators from collaborating institutions have been actively and productively engaged in the creation of the Sentinel Initiative, including the Mini-Sentinel pilot program, which has become an exciting and powerful research resource,” write Bruce M. Psaty, M.D., Ph.D., and Eric B. Larson, M.D., M.P.H., of the University of Washington, Seattle.

In this Viewpoint, the authors discuss the Mini-Sentinel program.

“Major benefits and the major harms are often best represented separately—an approach that allows patients and physicians to incorporate their own preferences about particular risks or benefits. In updating the postmarket risk-benefit profile, the FDA should ensure that the full range of expertise is brought to bear on the decision-making process. In some instances, the postmarket active surveillance may also result in regulatory action. For many regulatory actions, Mini-Sentinel can also provide a timely mechanism for tracking their effects on the use of the medicinal product and the health of the public.”

 Developing Quality Measures to Address Overuse

“Medical societies and other organizations have worked for many years to develop quality measures to assess underuse of beneficial health care services (e.g., failure to use antiplatelet therapy for patients with acute myocardial infarction). More recently, organizations have begun efforts to address unnecessary tests and treatments and the high costs of health care by developing ‘overuse’ measures,” write Jason S. Mathias, M.D., M.S., and David W. Baker, M.D., M.P.H., of the Feinberg School of Medicine, Northwestern University, Chicago. Overuse is defined as the use of a service that is unlikely to improve patient outcomes or for which potential harms exceed likely benefits.

The standards for developing and evaluating overuse measures are not clearly defined and may differ from those for underuse measures. In this Viewpoint, the authors examine two key issues that need “careful consideration in the development, implementation, and evaluation of overuse measures as compared with more typical underuse measures: level of evidence and mitigating potential unintended consequences.”

“Compared with traditional underuse measures, the rules of evidence for developing overuse measures are less well defined, and thoughtful strategies are needed to avoid unintended consequences of overuse measures. When carefully developed, implemented, and monitored, overuse measures have the potential to be part of the solution to the cost, quality, and safety problems in the U.S. health care system.”

Maternal Influenza May be Risk Factor for Bipolar Disorder In Adult Offspring

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 8, 2013

Media Advisory: To contact study author Alan S. Brown, M.D., M.P.H., call Dacia Morris at 212-543-5421 or email MorrisD@nyspi.columbia.edu.

 

JAMA Psychiatry Study Highlights

 

Maternal Influenza May be Risk Factor for Bipolar Disorder In Adult Offspring

 

A study by Raveen Parboosing, M.B.Ch.B., M.Med., F.C.Path(SA)(Viro), M.S., of Albert Luthuli Central Hospital, Durban, South Africa, and colleagues suggests that maternal influenza during pregnancy may be a risk factor for bipolar disorder in their offspring.

 

The study, which used a birth cohort from the Child Health and Development Study (CHDS), Kaiser Permanente and county health care databases, included 92 cases of bipolar disorder (BD) confirmed among 214 study participants and 722 control participants.

 

Researchers found a nearly four-fold increase in the risk of BD (odds ratio, 3.82) after exposure to maternal influenza at any time during pregnancy.

 

“In conclusion, the findings of this study suggest that gestational infection with the influenza virus confers a nearly four-fold increased risk of BD in adult offspring. If confirmed by studies in other birth cohorts, these findings may have implications for prevention and identification of pathogenic mechanisms that lead to BD. Further work, including serologic studies for maternal influenza antibody in archived specimens from this cohort is warranted,” the study concludes.

Genetic Variations Associated With Susceptibility to Bacteria Linked to Stomach Disorders

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 7, 2013

Media Advisory: To contact corresponding author Markus M. Lerch, M.D., F.R.C.P., email lerch@uni-greifswald.de. To contact editorial author Emad M. El-Omar, M.D., email e.el-omar@abdn.ac.uk.


CHICAGO – Two genome-wide association studies and a subsequent meta-analysis have found that certain genetic variations are associated with susceptibility to Helicobacter pylori, a bacteria that is a major cause of gastritis and stomach ulcers and is linked to stomach cancer, findings that may help explain some of the observed variation in individual risk for H pylori infection, according to a study in the May 8 issue of JAMA.

“[H pylori] is the major cause of gastritis (80 percent) and gastroduodenal ulcer disease (15 percent-20 percent) and the only bacterial pathogen believed to cause cancer,” according to background information in the article. “H pylori prevalence is as high as 90 percent in some developing countries but 10 percent of a given population is never colonized, regardless of exposure. Genetic factors are hypothesized to confer H pylori susceptibility.”

Julia Mayerle, M.D., of University Medicine Greifswald, Greifswald, Germany, and colleagues conducted a study to identify genetic loci associated with H pylori seroprevalence. Two independent genome-wide association studies (GWASs) and a subsequent meta-analysis were conducted for anti-H pylori immunoglobulin G (IgG) serology in the Study of Health in Pomerania (SHIP) (recruitment, 1997-2001 [n =3,830]) as well as the Rotterdam Study (RS-I) (recruitment, 1990-1993) and RS-II (recruitment, 2000-2001 [n=7,108]) populations. Whole-blood RNA gene expression profiles were analyzed in RS-III (recruitment, 2006-2008 [n = 762]) and SHIP-TREND (recruitment, 2008-2012 [n=991]), and fecal H pylori antigen in SHIP-TREND (n=961).

Of 10,938 participants, 6,160 (56.3  percent) were seropositive for H pylori. GWAS meta-analysis identified an association between the gene TLR1 and H pylori seroprevalence, “a finding that requires replication in non-white populations,” the authors write.

“At this time, the clinical implications of the current findings are unknown. Based on these data, genetic testing to evaluate H pylori susceptibility outside of research projects would be premature.”

“If confirmed, genetic variations in TLR1 may help explain some of the observed variation in individual risk for H pylori infection,” the researchers conclude.

Editorial: Helicobacter pylori Susceptibility in the GWAS Era

In an accompanying editorial, Emad M. El-Omar, M.D., of Aberdeen University, Aberdeen, United Kingdom, writes that the authors of this study are appropriate to state, “based on their data, genetic testing to evaluate H pylori susceptibility is premature.”

“This would be superfluous, because nongenetic testing for the infection can be accomplished at a fraction of the cost. There is a bigger picture: understanding genetic susceptibility to H pylori is essential for understanding how to overcome this infection. The current approach to eradication of the infection is limited and based entirely on prescribing a cocktail of antibiotics with an acid inhibitor to symptomatic individuals. However, H pylori antibiotic resistance is increasing steadily, and eventually curing even benign conditions such as peptic ulcer disease arising from H pylori will be difficult. When considering gastric cancer, another H pylori-induced global killer, the necessity for understanding the pathogenesis of the infection and the role of host genetics in susceptibility is even greater. The corollary is that better understanding of infections, including genetic epidemiology, is crucial to design measures to eradicate the downstream consequences of H pylori in large populations.”

Study Evaluates Effect of Increasing Detection Intervals in ICDs on Pacing Function, ICD Shocks Delivered, and Inappropriate Shocks

EMBARGOED FOR RELEASE: 3 P.M. (CT) TUESDAY, MAY 7, 2013

Media Advisory: To contact Maurizio Gasparini, M.D., email maurizio.gasparini@humanitas.it. To contact editorial author Merritt H. Raitt, M.D., call Tamara Hargens-Bradley at 503-494-8231 or email hargenst@ohsu.edu.


CHICAGO – Programming an implantable cardioverter-defibrillator (ICD) with a long-detection interval compared with a standard-detection interval resulted in a reduction in anti-tachycardia pacing episodes, ICD shocks delivered, and inappropriate shocks, according to a study in the May 8 issue of JAMA.

“Therapy with ICDs is now the standard of care in primary and secondary prevention. As indications for implants have expanded, concern about possible adverse effects of ICD therapies on prognosis and quality of life has arisen. Several authors have reported that ICD therapies, both appropriate and inappropriate, are associated with an increased risk of death and worsening of heart failure. To reduce these unfavorable outcomes, several studies have focused on identifying the best device programming strategies, either by targeting the anti-tachycardia pacing [ATP; use of pacing stimulation techniques for termination of tachyarrhythmias] algorithms for interrupting fast ventricular tachyarrhythmias [abnormal heart rhythm] or by investigating the use of prolonged arrhythmia detection intervals,” according to background information in the article. “Using more intervals to detect ventricular tachyarrhythmias has been associated with reducing unnecessary ICD therapies.”

Maurizio Gasparini, M.D., of the Humanitas Clinical and Research Center, Rozzano, Italy, and colleagues conducted a study (ADVANCE III) to determine whether using 30 of 40 intervals to detect ventricular arrhythmias (VT) (long detection) during spontaneous fast VT episodes reduces ATP and shock delivery more than 18 of 24 intervals (standard detection). The randomized trial included 1,902 primary and secondary prevention patients (average age, 65 years; 84 percent men; 75 percent primary prevention ICD) with ischemic and nonischemic etiology undergoing first ICD implant at 1 of 94 international centers (March 2008-December 2010). Patients were randomized 1:1 to programming with long (n=948) or standard-detection (n=954) intervals.

Overall, 530 episodes were recorded and classified by the devices as ventricular arrhythmias. During a median (midpoint) follow-up of 12 months, the long-detection group had a 37 percent lower rate of delivered therapies (ATP and shocks) (346 vs. 557) compared to the standard-interval detection group. Estimates of the time to the first ICD therapy (ATP or shock) showed a significantly lower probability of receiving a therapy in the long-detection group.

The researchers also found that the frequency of appropriate shocks was similar between the groups, while the long-detection group was associated with a significantly lower incidence (45 percent lower rate) of inappropriate shocks. In addition, a lower hospitalization rate was observed in the long-detection group. No significant difference in mortality rates was seen between the groups.

“ADVANCE III demonstrated that the use of a long detection setting, in ICDs with the capability of delivering ATP during capacitor charge, significantly reduced the rate of ventricular therapies delivered and inappropriate shocks compared with the standard detection setting,” the authors write. “This programming strategy may be a useful approach for ICD recipients.”

Editorial: Reducing Shocks and Improving Outcomes With Implantable Defibrillators

Merritt H. Raitt, M.D., of the Portland Veterans Administration Medical Center and Oregon Health and Science University, Portland, comments on the findings of this study in an accompanying editorial.

“The findings from the ADVANCE III trial by Gasparini et al add important new information to the evidence base of ICD programming for prevention of ventricular arrhythmias. Regardless of whether these programming interventions lead to reduced mortality, the unequivocal reduction in ICD shocks and the reduction in hospitalization without an increase in adverse events such as syncope suggests that this programming approach should be considered for adoption in the care of patients with ICDs and clinical characteristics similar to those enrolled in these studies.”

Adding Omega-3 Fatty Acids and Lutein/Zeaxanthin to Formulation Does Not Further Reduce Risk of Progression to Advanced AMD

EMBARGOED FOR EARLY RELEASE: 6 P.M. (CT) SUNDAY, MAY 5, 2013

Media Advisory: To contact Emily Y. Chew, M.D., call Jean Horrigan at 301-496-5248 or email jh@nei.nih.gov.


CHICAGO – In a large, multicenter, randomized clinical trial that included persons at high risk for progression to advanced age-related macular degeneration (AMD), adding the carotenoids lutein and zeaxanthin, the omega-3 fatty acids DHA and EPA, or both to a formulation of antioxidant vitamins and minerals that has shown effectiveness in reducing risk did not further reduce risk of progression to advanced AMD, according to a study published by JAMA. The study is being released early online to coincide with its presentation at the Association for Research in Vision and Ophthalmology annual meeting.

“Age-related macular degeneration , the leading cause of blindness in the developed world, accounts for more than 50 percent of all blindness in United States,” according to background information in the article. In 2004 it was estimated that 8 million individuals had intermediate AMD and approximately 2 million had advanced AMD, with no effective proven therapies for atrophic AMD. “Without more effective ways of slowing progression, the number of persons with advanced AMD is expected to double over the next 20 years, resulting in increasing socioeconomic burden,” the authors write. “Oral supplementation with the Age-Related Eye Disease Study (AREDS) formulation (antioxidant vitamins C, E, and beta carotene and zinc) has been shown to reduce the risk of progression to advanced AMD. Observational data suggest that increased dietary intake of lutein and zeaxanthin, omega-3 long-chain polyunsaturated fatty acids (docosahexaenoic acid [DHA] and eicosapentaenoic acid [EPA]), or both might further reduce this risk.”

Emily Y. Chew, M.D., of the National Eye Institute, National Institutes of Health, Bethesda, Md., and colleagues with the Age-Related Eye Disease Study 2 (AREDS2) Research Group examined whether adding lutein + zeaxanthin, DHA + EPA, or both to the AREDS formulation might further reduce the risk of progression to advanced AMD. A secondary goal was to evaluate the effect of eliminating beta carotene, lowering zinc doses, or both in the AREDS formulation. AREDS2, a multicenter, randomized phase 3 study was conducted in 2006-2012, enrolling 4,203 participants 50 to 85 years of age at risk for progression to advanced AMD with bilateral large drusen (tiny yellow or white deposits in the retina of the eye or on the optic nerve head) or large drusen in 1 eye and advanced AMD in the fellow eye.

Participants were randomized to receive lutein (10 mg) and zeaxanthin (2 mg), DHA (350 mg) + EPA (650 mg), lutein + zeaxanthin and DHA + EPA, or placebo. All participants were also asked to take the original AREDS formulation or accept a secondary randomization to 4 variations of the AREDS formulation, including elimination of beta carotene, lowering of zinc dose, or both.

A total of 1,608 participants had experienced at least 1 advanced AMD event by the end of the study (1,940 events in 6,891 study eyes). The researchers found that the probabilities of progression to advanced AMD by 5 years were 31 percent for placebo, 29 percent for lutein + zeaxanthin, 31 percent for DHA + EPA, and 30 percent for lutein + zeaxanthin and DHA + EPA. In the primary analyses, comparisons with placebo demonstrated no statistically significant reductions in progression to advanced AMD.

“There was no apparent effect of beta carotene elimination or lower-dose zinc on progression to advanced AMD. More lung cancers were noted in the beta carotene vs. no beta carotene group (23 [2 percent] vs. 11 [0.9 percent]), mostly in former smokers,” the authors write.

None of the nutrients affected development of moderate or worse vision loss.

The researchers add that “these null results may be attributable to the true lack of efficacy. Other factors to consider include inadequate dose, inadequate duration of treatment, or both.”

“Based on apparent risks of beta carotene and possible benefits that are only evident within exploratory subgroup analyses, lutein + zeaxanthin requires further investigation for potential inclusion in the AREDS supplements.”

Study Examines Effect of Different Oxygen Saturation Levels on Death or Disability in Extremely Preterm Infants

EMBARGOED FOR EARLY RELEASE: 8:15 A.M. (CT) SUNDAY, MAY 5, 2013

Media Advisory: To contact Barbara Schmidt, M.D., M.Sc., call Alison Fraser at 267-426-6054 or email FraserA1@email.chop.edu. To contact editorial co-author Eduardo Bancalari, M.D., call Lisa Worley at 305-243-5184 or email LWorley2@med.miami.edu.


CHICAGO – In a randomized trial performed to help resolve the uncertainty about the optimal oxygen saturation therapy in extremely preterm infants, researchers found that targeting saturations of 85 percent to 89 percent compared with 91 percent to 95 percent had no significant effect on the rate of death or disability at 18 months, according to a study published by JAMA. The study is being released early online to coincide with its presentation at the Pediatric Academic Societies annual meeting.

“Extremely preterm infants are monitored with pulse oximeters for several weeks after birth because they may require supplemental oxygen intermittently or continuously. The goal of oxygen therapy is to deliver sufficient oxygen to the tissues while minimizing oxygen toxicity and oxidative stress. It remains uncertain what values of arterial oxygen saturations achieve this balance in immature infants, who are especially vulnerable to the harmful effects of oxygen,” according to background information in the article.

Barbara Schmidt, M.D., M.Sc., of the Children’s Hospital of Philadelphia and University of Pennsylvania, Philadelphia, and colleagues conducted a study to compare the effects of targeting lower or higher arterial oxygen saturations in extremely preterm infants on the rate of death or disability. The randomized trial, conducted in 25 hospitals in Canada, the United States, Argentina, Finland, Germany, and Israel, included 1,201 infants with gestational ages of 23 weeks 0 days through 27 weeks 6 days, who were enrolled within 24 hours after birth between December 2006 and August 2010. Follow-up assessments began in October 2008 and ended in August 2012.

Study participants were monitored until postmenstrual ages (the time elapsed between the first day of the mother’s last menstrual period and birth [gestational age] plus the time elapsed after birth [chronological age]) of 36 to 40 weeks with pulse oximeters that displayed saturations of either 3 percent above or below the true values. Caregivers adjusted the concentration of oxygen to achieve saturations between 88 percent and 92 percent, which produced 2 treatment groups with true target saturations of 85 percent to 89 percent (n=602) or 91 percent to 95 percent (n=599). Alarms were triggered when displayed saturations decreased to 86 percent or increased to 94 percent. The primary outcome was a composite of death, gross motor disability, cognitive or language delay, severe hearing loss, or bilateral blindness at a corrected age of 18 months. Secondary outcomes included retinopathy of prematurity and brain injury.

The researchers found that targeting lower compared with higher oxygen saturations had no significant effect on the rate of death or disability at 18 months. “Of the 578 infants with data for this outcome who were assigned to the lower target range, 298 (51.6 percent) died or survived with disability compared with 283 of the 569 infants (49.7 percent) assigned to the higher target range,” the authors write. “Of the 585 infants with known vital status at 18 months in the lower saturation target group, 97 (16.6 percent) had died compared with 88 of 577 (15.3 percent) in the higher saturation target group.”

Targeting lower compared with higher saturations reduced the average postmenstrual age at last use of oxygen therapy, but had no significant effect on any other outcomes, including the rate of severe retinopathy of prematurity.

“Clinicians who try to translate the disparate results of the recent oxygen saturation targeting trials into their practice may find it prudent to target saturations between 85 percent and 95 percent while strictly enforcing alarm limits of 85 percent at all times, and of 95 percent during times of oxygen therapy. Our findings do not support recommendations that targeting saturations in the upper 80 percent range should be avoided. Because it is very difficult to maintain infants in a tight saturation target range, such recommendations may lead to increased tolerance of saturations above 95 percent and an increased risk of severe retinopathy. Although no longer a major cause of bilateral blindness, severe retinopathy remains a marker of serious childhood disabilities,” the authors conclude.

Editorial: Oxygenation Targets and Outcomes in Premature Infants

In an accompanying editorial, Eduardo Bancalari, M.D., and Nelson Claure, M.Sc., Ph.D., of the University of Miami Miller School of Medicine, comment on the findings of this and other studies that have examined this issue.

“Oxygen therapy continues to present neonatal clinicians with a difficult conundrum where efforts to reduce complications associated with hyperoxemia in premature infants may affect their survival. How the results of these trials should be translated into clinical practice is still controversial. If the long-term outcomes are not affected by the different saturation targets, should the shorter-term outcomes of death, severe retinopathy of prematurity, and bronchopulmonary dysplasia be used to formulate a recommendation? After all, no other outcome is as important as survival. Until the remaining questions raised by these studies are answered by the combined meta-analysis or new evidence becomes available, minimizing extreme oxygenation levels by targeting saturations between 90 and 95 percent appears to be a reasonable approach.”

Risk of Death Has Decreased Substantially For Children Initially Treated With Dialysis for End-Stage Kidney Disease

EMBARGOED FOR EARLY RELEASE: 11:15 A.M. (CT) SATURDAY, MAY 4, 2013

Media Advisory: To contact corresponding author Bethany J. Foster, M.D., M.Sc., call Julie Robert at 514-934-1934 ext. 71381; or email julie.robert@muhc.mcgill.ca.


CHICAGO – In a study that included more than 20,000 patients, there was a significant decrease in the United States in mortality rates over time among children and adolescents initiating end-stage kidney disease treatment with dialysis between 1990 and 2010, according to a study in the May 8 issue of JAMA. The study is being released early online to coincide with its presentation at the Pediatric Academic Societies annual meeting.

“Individuals with end-stage kidney disease (ESKD) face a significantly shortened life expectancy. In no group of ESKD patients is the loss of potential years of life larger than in children and adolescents. Although transplant remains the treatment of choice to maximize survival, growth, and development, 75 percent of children with ESKD require treatment with dialysis prior to receiving a kidney transplant. Dialysis is therefore a life-saving therapy for children with ESKD while they await transplant. Nevertheless, all-cause mortality rates in children receiving maintenance dialysis are at least 30 times higher than the general pediatric population, with even higher relative risks in very young children,” the authors write. “There have been substantial improvements in the care of children with ESKD between 1990 and 2010. However, to our knowledge, it is not known if mortality has changed over time in the United States, particularly in recent years.”

Mark M. Mitsnefes, M.D., M.Sc., of Cincinnati Children’s Hospital Medical Center, and colleagues conducted a study to determine if all-cause, cardiovascular, and infection-related mortality rates have changed between 1990 and 2010 among patients younger than 21 years of age with ESKD initially treated with dialysis and if changes in mortality rates over time differed by age at treatment initiation. The researchers used data from the United States Renal Data System. Children with a prior kidney transplant were excluded.

The researchers identified 23,401 children and adolescents who met study criteria. Crude mortality rates during dialysis treatment were higher among children younger than 5 years at the start of dialysis compared with those who were 5 years and older. The authors found that the all-cause mortality risk decreased progressively over calendar time for both those younger than 5 years and those 5 years and older at initiation. There was also a decrease over calendar time for cardiovascular and infection-related mortality risk among children younger than 5 years at initiation and among those 5 years and older.

“Numerous factors may have contributed to the observed reductions in mortality risk over time. Improved pre-dialysis care, advances in dialysis technology, and greater experience of clinicians may each have played a role,” the authors write.

“Almost all children initiating ESKD treatment are considered eligible for transplant. However, most will require dialysis during their lifetime, either before transplant or after allograft loss. In the United States, there was a significant decrease in mortality rates over time among children and adolescents initiating ESKD treatment with dialysis between 1990 and 2010. Further research is needed to determine the specific factors responsible for this decrease.”

Study Examines Cognitive Impairment in Families With Exceptional Longevity

 

A study by Stephanie Cosentino, Ph.D., of Columbia University, New York, and colleagues examines the relationship between families with exceptional longevity and cognitive impairment consistent with Alzheimer disease. (Online First)

 

The cross-sectional study included a total of 1,870 individuals (1,510 family members and 360 spouse controls) recruited through the Long Life Family Study. The main outcome measure was the prevalence of cognitive impairment based on a diagnostic algorithm validated using the National Alzheimer’s Coordinating Center data set.

 

According to study results, the cognitive algorithm classified 546 individuals (38.5 percent) as having cognitive impairment consistent with Alzheimer disease. Long Life Family Study probands had a slightly but not statistically significant reduced risk of cognitive impairment compared with spouse controls (121 of 232 for probands versus 45 of 103 for spouse controls), whereas Long Life Family Study sons and daughters had a reduced risk of cognitive impairment (11 of 213 for sons and daughters versus 28 of 216 for spouse controls). Restriction to nieces and nephews in the offspring generation attenuated this association (37 of 328 for nieces and nephews versus 28 of 216 for spouse controls).

 

“Overall, our results appear to be consistent with a delayed onset of disease in long-lived families, such that individuals who are part of exceptionally long-lived families are protected but not later in life,” the study concludes.

JAMA Internal Medicine Study Highlights

Study Examines Spiritual Support For Patients with Advanced Cancer

 

A study by Tracy A. Balboni, M.D., M.P.H., of the Dana-Farber Cancer Institute, Boston, and colleagues suggests that spiritual care and end-of-life (EoL) discussions by the medical team may be associated with reduced aggressive treatment.

 

The study included 343 patients with advanced cancer. EoL care in the final week included hospice, aggressive EoL measures (care in an intensive care unit, resuscitation or ventilation), and ICU death.

 

Patients reporting high spiritual support from religious communities were less likely to receive hospice (adjusted odds ratio [AOR], 0.37), more likely to receive aggressive EoL measures (AOR, 2.62), and more likely to die in an ICU (AOR, 5.22), according to the results. The results also indicate that among patients well-supported by religious communities, receiving spiritual support from the medical team was associated with higher rates of hospice use (AOR, 2.37), fewer aggressive treatments ((AOR, 0.23), fewer ICU deaths (AOR, 0.19) and EoL discussions were associated with fewer aggressive interventions (AOR, 0.12).

 

“In conclusion, terminally ill patients receiving high spiritual support from religious communities receive more-intensive EoL medical care, including less hospice, more aggressive interventions, and more ICU deaths, particularly among racial/ethnic minority and high religious coping patients,” the study concludes. “The provision of spiritual care and EoL discussions by medical teams to patients highly supported by religious communities is associated with reduced medical care intensity near death.”

Study Suggests Preordering School Lunches Leads to Healthier Choices

 

A research letter by Andrew S. Hanks, Ph.D., of Cornell University, Ithaca, New York, and colleagues examined whether having students preorder their entrée (main dish) of their school meal improves the healthfulness of entrees selected for lunch. (Online First)

 

A total of 272 students in 14 classrooms (grades 1-5) from two elementary schools in upstate New York participated in the study. The schools are located in a predominantly white (96.6 percent) county where 55 percent of students receive free or reduced-price lunches. Students used an electronic system to preorder their lunch entrée over a 4-week period (November – December 2011).

 

According to the study results, when students preordered their entrée, 29.4 percent selected the healthier entrée compared with 15.3 percent when preordering was not available. The less healthy entrée was chosen 70.8 percent of the time by students who preordered, and students who ordered in the lunch line selected the less healthy entrée 85.7 percent of the time. It appears that hunger-based, spontaneous selection diminished healthy entrée selection by 48 percent and increased less healthy entrée selection by 21 percent.

 

“Together, both consumption and selection data demonstrate how a simple environmental change—preordering—can prompt children to choose healthier food” the study concludes.

Short-Term Food Deprivation Appears Linked to High-Calorie Food Options

 

A research letter by Brian Wansink, Ph.D., and Aner Tal, Ph.D., of Cornell University, Ithaca, N.Y., suggests that hungry grocery shoppers tend to buy higher-calorie products.

 

The research included a laboratory study in which 68 paid participants were asked to avoid eating five hours prior to the study, although during some of the sessions some of the participants were given crackers so they would no longer feel hungry. A follow-up field study tracked the purchases of 82 participants at different times of the day when they were most likely to be full or hungry.

 

According to the results, hungry laboratory participants chose a higher number of higher-calorie products but there were no differences between conditions in the number of lower-calorie choices and the total number of food items selected. Field study shoppers who completed the study at times when they were more likely to be hungry (between 4-7 p.m.) bought less low-calorie food relative to high-calorie food options compared with those who completed the study when they were less likely to be hungry, the results also indicate.

 

“Even short-term food deprivation can lead to a shift in choices such that people choose less low-calorie, and relatively more high-calorie, food options. Given the prevalence of short-term food deprivation, this has important health implications,” the study concludes.

Study Suggests Childhood Adversities Association With Health Outcomes of Early Adolescents

 

A study by Emalee G. Flaherty, M.D., of the Ann and Robert H. Laurie Children’s Hospital of Chicago, Illinois, and colleagues suggests childhood adversities, particularly recent adversities, are associated with health outcomes by early adolescence. (Online First)

 

A total of 933 children who completed an interview at age 14 years and are part of the Longitudinal Studies of Child Abuse and Neglect participated in the study. Eight categories of adversity experienced during the first 6 years of life, the second 6 years of life, the most recent 2 years, and overall adversity were examined. The main outcome measures were child health problems including poor health, illness requiring a doctor, somatic concerns, and any health problem at age 14 years.

 

More than 90 percent of the youth had experienced an adverse childhood event by age 14 years. There was a graded relationship between adverse childhood exposures and any health problem, while two and three or more adverse exposures were associated with somatic concerns. Recent adversity appeared to uniquely predict poor health, somatic concerns, and any health problem.

 

“These findings suggest that greater efforts to minimize or ameliorate childhood adversities, especially those occurring during adolescence, will have a demonstrable impact on the health of adolescents and adults,” the study concludes.

Study Examines Utilization, Outcomes, Costs of Inpatient Surgery at Critical Access Hospitals

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 1, 2013

JAMA Surgery Study Highlights


A study by Adam J. Gadzinski, M.D., M.S., of the University of Michigan, Ann Arbor, and colleagues examined the utilization, outcomes and costs of inpatient surgery performed at critical access hospitals (CAHs). (Online First)

 

Researchers performed a retrospective cohort study of patients undergoing inpatient surgery from 2005 through 2009 at CAHs or non-CAHs using data from the Nationwide Inpatient Sample and American Hospital Association. Among the 1,283 CAHs and 3,612 non-CAHs reporting to the American Hospital Association, 34.8 percent and 36.4 percent respectively, had at least one year of data in the Nationwide Inpatient Sample. The main outcome measures were in-hospital mortality, prolonged length of stay, and total hospital costs.

 

General surgical, gynecologic, and orthopedic procedures composed 95.8 percent of in-patient cases at CAHs versus 77.3 percent at non-CAHs. For eight common procedures examined, mortality was equivalent between CAHs and non-CAHs, with the exception that Medicare beneficiaries undergoing hip fracture repair in CAHs had a higher risk of in-hospital death. However, despite shorter hospital stays, costs at CAHs were 9.9 percent to 30.1 percent higher, the study finds.  

 

“In-hospital mortality for common low-risk procedures is indistinguishable between CAHs and non-CAHs. Although our findings suggest the potential for cost savings, changes in payment policy for CAHs could diminish access to essential surgical care for rural populations,” the authors conclude.

Drinking to Alleviate Mood Symptoms Associated With Alcohol Dependence

EMBARGOED FOR RELEASE: 3 P.M. (CT), WEDNESDAY, MAY 1, 2013

Media Advisory: To contact study author Rosa M. Crum, M.D., M.H.S., call Tim Parsons at 410-955-7619 or email tmparson@jhsph.edu.

JAMA Psychiatry Study Highlights


Rosa M. Crum, M.D., M.H.S., of the Johns Hopkins Health Institutions, Baltimore, Md., and colleagues examined whether self-medicating mood symptoms is associated with the increased probability of the onset and persistence of alcohol dependence.

 

The study included a nationally representative sample of the U.S. population with drinkers at risk for alcohol dependence among the 43,093 adults surveyed in 20001 and 2002; 34,653 of whom were reinterviewed in 2004 and 2005.

 

The study results indicate that the report of alcohol self-medication of mood symptoms was associated with increased odds of incident alcohol dependence at follow-up (adjusted odds ratio [AOR], 3.10) and persistence of dependence (AOR, 3.45).

 

“Drinking to alleviate mood symptoms is associated with the development of alcohol dependence and its persistence once dependence develops. These associations occur among individuals with subthreshold mood symptoms, with DSM-IV affective disorders, and for those who have received treatment. Drinking to self-medicate mood symptoms may be a potential target for prevention and early intervention efforts aimed at reducing the occurrence of alcohol dependence,” the study concludes.
