Bottom Line: This observational study examined alcohol consumption and the risk of dementia and cognitive decline in older adults with or without mild cognitive impairment (MCI). The study analyzed 3,021 adults (72 and older) who were free of dementia (2,548 were without MCI and 473 with MCI). During about six years of follow-up, there were 512 cases of dementia, including 348 cases of Alzheimer disease. Among those adults without MCI, no amount of alcohol consumption was significantly associated with higher risk for dementia compared with drinking less than one drink per week. Among those adults with MCI, the risk of dementia according to numbers of alcoholic drinks per week wasn’t statistically significant, although it appeared to be highest for drinking more than 14 drinks per week compared with less than one drink. The association between alcohol intake and cognitive decline was affected by the presence of MCI at the study start. Difference in scores reflecting cognitive decline at follow-up by alcohol consumption were statistically significant only among those with MCI at baseline, with the biggest decline associated with more than 14 drinks per week. Limitations of the study include self-reported alcohol consumption. The findings warrant further study and physicians should address the drinking behavior when caring for older patients.

Bottom Line: This observational study estimates life expectancy at age 25 and to what extent causes of death are associated with differences in life expectancy based on the level of education attained by U.S. adults. The analysis included 2.2 million deaths in 2010 and 2.4 million deaths in 2017. Between those years, life expectancy at age 25 declined overall from 79.34 to 79.15 years in an analysis limited to white and black non-Hispanic adults because other racial/ethnic groups were too small or less reliably identified in the national vital statistics system. While life expectancy decreased for white adults, it didn’t change significantly for black men and it increased among black women. Life expectancy decreased among adults with less than a four-year college degree and increased among the college educated. Much of the increasing educational differences in years of life lost may be related to deaths from drug use, especially among white men and women. Some limitations of the study are related to the nature of the data used.

Bottom Line: Eating plant protein was associated with lower risk of death in a Japanese population in this observational study. The study included 70,696 people, the majority of whom were women, with an average age of about 55. It examined associations between eating animal and plant protein and the risk of death overall and from specific causes. Information on what people ate came from a food questionnaire; data were collected from 1995 through 1999 and follow-up was completed through 2016, during which time there were 12,381 deaths documented. Study authors report that eating animal protein wasn’t associated with mortality outcomes but higher intake of plant protein was associated with lower risk of death overall and death related to cardiovascular disease. Replacing red meat protein or processed meat protein with plant protein was associated with lower risk of death overall and death related to cancer and cardiovascular disease. Limitations of the study include a single assessment of dietary information so eating habits may have changed over time and participants with chronic disease were excluded from the study. The study suggests encouraging diets with more intake of plant-based protein could contribute to better health and longevity.

Former NFL Players With History of Concussion Symptoms More Likely to Report Low Testosterone, Erectile Dysfunction

Bottom Line: In a study of 3,409 former NFL players, a self-reported history of concussion symptoms was associated with an increased likelihood of self-reported low testosterone levels and erectile dysfunction (ED), even among those players reporting relatively few concussion symptoms when they were injured. Previous studies have suggested head trauma in men may be associated with low testosterone levels and sexual dysfunction, possibly because of trauma-induced damage to the pituitary gland. In this study, former football players were surveyed about experiencing concussion symptoms while playing or practicing professional football and, if they had, how many times. In addition, they were asked if a health care provider ever recommended or prescribed medication for low testosterone or ED and if they were currently taking medication for those conditions. Of the players, 18.3% had indicators for low testosterone levels and 22.7% had indicators of ED. Former players in the group reporting the highest number of concussion symptoms were about twice as likely to report low testosterone compared to those with the fewest symptoms; the association was similar for ED in analyses that accounted for demographic, current health and football-related factors including position played. The study has a number of limitations, including indirect measures of low testosterone levels and ED, and concussion data that were collected after a player’s career ended and that relied on memory recall. Also, it isn’t known whether the men had low testosterone levels or ED before they started playing in the NFL. The study authors suggest their findings might encourage clinicians to ask men with brain injuries about the treatable conditions of low testosterone levels and ED.

Bottom Line: Heart disease, stroke, diabetes and hypertension death rates (adjusted for age to account for different ages in the population) were examined from 1999 to 2017 in the United States in this study that used data from the Centers for Disease Control and Prevention. Researchers report the overall rate of death from heart disease decreased over time but the rate of decline slowed after 2010; deaths from stroke and diabetes declined from 1999 to 2010 but leveled off after that; and deaths from high blood pressure increased between 2010 and 2017. Black individuals had higher age-adjusted mortality rates compared with whites. A limitation of the study is the use of death certificate data, which can be miscoded.

Estimates of Potential Gains if U.S. Had Less Restrictive Acceptance Practices for Donor Kidneys

JAMA Internal Medicine

Bottom Line: A study of donated kidneys from deceased donors in the United States and France between 2004 and 2014 estimates the effect of less restrictive acceptance practices for organ donation like those in France on the donor pool and potential survival benefits for wait-listed U.S. patients. The authors of this observational study report 156,089 kidneys were recovered from deceased donors in the United States during that period, of which 128,102 were transplanted and 27,987 (17.9%) were discarded. In France, 29,984 kidneys were recovered during that time with 27,252 transplanted and 2,732 (9.1%) discarded. The average age of donors in France was higher (56 compared with 39 in the United States by 2014) and France accepted lower-quality kidneys for transplantation. The analyses suggests that if the French-based organ allocation model was applied to deceased donor kidneys in the United States, then 17,435 (62%) of discarded kidneys could have been transplanted and provided potentially years of added survival for patients. Limitations of the study include that analysis of data from 2004 to 2014 cannot assess if the new organ allocation system implemented in 2014 in the United States impacted organ utilization but another study suggests the kidney discard rate didn’t improve after 2014 when changes to kidney allocation were implemented.

Bottom Line: Incarceration during childhood of a parental figure (biological, adopted or stepparents or any adult responsible for a child’s care and discipline) appears to be associated with children’s psychiatric, legal, financial and social outcomes as young adults. This observational study used data from parents and children (ages 9 to 16; 1,420 participants) in rural North Carolina, with children followed up through young adulthood with almost 94% of them interviewed at least once up to age 30. By age 16, 23.9% (a weighted percentage) of children had an incarcerated parental figure, most commonly a biological father who was living outside the home. Parental incarceration was common and disproportionately so among African American and American Indian families. Study authors report parental incarceration was associated with childhood emotional and behavioral disorders and adversity in analyses that accounted for sex and race/ethnicity. In young adulthood (after accounting for childhood psychiatric diagnoses and adversity), parental incarceration was associated with an increased likelihood of having an anxiety disorder, an illicit drug use disorder, a felony charge, being incarcerated, not finishing high school, becoming a parent when younger than 18, and being socially isolated. Limitations of the study include that its sample of participants isn’t representative of the U.S. population and its observational design means the findings should be retested.

Is Greater PTSD Symptom Reduction in Veterans Associated With Lower Diabetes Risk?

Bottom Line: This observational study examined whether veterans who experienced a greater reduction in symptoms of posttraumatic stress disorder (PTSD) had an associated lower risk of developing type 2 diabetes. PTSD is associated with an increased risk of type 2 diabetes, which may be partly explained by the greater likelihood of type 2 diabetes risk factors among individuals with PTSD. The analysis included medical records from nearly 1,600 veterans who received PTSD specialty care and had symptoms of PTSD assessed on a checklist questionnaire. Clinically meaningful improvement in PTSD symptoms constituted a greater score decrease on the checklist compared with less or no improvement in symptoms as reflected in a smaller score decrease during a 12-month period. During two to six years of follow-up, there were 105 new cases of type 2 diabetes, including new cases among 2.6% of veterans with a clinically meaningful improvement in symptoms and 5.9% of patients without that level of improvement. After accounting for factors that could influence the outcomes, patients with clinically meaningful improvement in symptoms were less likely to develop type 2 diabetes compared with those without such improvement. Limitations of the study include that the follow-up time was insufficient to conclude that improvement in PTSD symptoms is associated with a reduced lifetime risk of type 2 diabetes. The results also may not be generalizable to those who aren’t veterans.

Bottom Line: An analysis of Framingham Heart Study data examined the association of the time between quitting smoking and new cases of cardiovascular disease (CVD). This analysis included nearly 8,800 individuals, including 2,371 heavy smokers who smoked 20 or more pack-years, which is equal to smoking one pack of cigarettes daily for 20 years. Over an average follow-up of 26 years, 2,435 first CVD events (heart attack, stroke, heart failure or cardiovascular death) occurred in the entire group, with 1,095 among heavy smokers. The authors report quitting smoking was associated with lower risk of CVD within five years for former heavy smokers compared with current smokers but their risk remained higher for 10 to 15 years after cessation compared with people who never smoked. Limitations of the study include its smaller sample size compared to some previous studies, and participants in the study were primarily white individuals of European ancestry, potentially limiting the generalizability of the findings to others.

Study Examines Maternal Exposure to Fluoride in Pregnancy, Kids’ IQ Scores

JAMA Pediatrics

EMBARGOED FOR RELEASE: 11 A.M. (ET), MONDAY, AUGUST 19, 2019

Bottom Line: An observational study of 601 mother-child pairs from six cities in Canada hints at an apparent association between maternal exposure to fluoride during pregnancy and lower IQ scores measured in children ages 3 to 4. Community water has been fluoridated for decades to prevent tooth decay; a majority of U.S. residents are supplied with fluoridated water, as are more than one-third of Canadian residents and about 3% of European residents. This study analyzed two measures of fluoride exposure during pregnancy. Data on maternal urinary fluoride concentrations and children’s IQ were available for 512 mother-child pairs, and self-reported consumption of tap water and other water-based drinks (tea and coffee) and IQ scores were available for 400 of the 601 mother-child pairs. After accounting for factors associated with fluoride metabolism and children’s intellectual abilities, a 1-mg/L increase in maternal urinary fluoride was associated with a 4.5-point lower IQ score in boys without a statistically significant association with IQ score in girls. A 1-mg higher intake of fluoride was associated with a 3.7 lower IQ score among boys and girls. The study’s conclusions are limited by its observational design, which can’t account for unmeasured factors that could explain the results, and there was no assessment of children’s fluoride exposure during infancy. An accompanying podcast discusses the meaning and implications of the findings.

USPSTF Recommendation on Screening, Genetic Counseling and Testing for BRCA-Related Cancer

JAMA

EMBARGOED FOR RELEASE: 11 A.M. (ET), TUESDAY, AUGUST 20, 2019

Media advisory: To contact the U.S. Preventive Services Task Force, email the Media Coordinator at Newsroom@USPSTF.net or call 202-572-2044. The full report, related articles and a podcast are linked to this news release.

Bottom Line: The U.S. Preventive Services Task Force (USPSTF) is broadening its recommendation on screening for potentially harmful mutations of the breast cancer susceptibility BRCA1/2 genes, which are associated with increased risk of certain cancers. The USPSTF now recommends primary care clinicians assess risk in women with a personal or family history of breast, ovarian, fallopian tube, or peritoneal (tissue lining the abdominal cavity) cancer or those who have an ancestry associated with BRCA1/2 mutations. Women with a positive result on that risk assessment should receive genetic counseling and, if indicated after counseling, genetic testing. The USPSTF recommends against routine risk assessment, genetic counseling, or genetic testing for women whose personal or family history or ancestry is not associated with BRCA1/2 mutations.

Bottom Line: This observational study analyzed survey data from 1,652 active-duty military personnel to examine associations between firearm ownership and storage practices with suicidal thoughts and behaviors. More than one-third (35.7%) of military personnel reported having a firearm in or around their homes, with 32.2% indicating their firearms were safely stored unloaded and locked up. Study authors report that although service members with recent thoughts about death or self-harm were less likely to report having firearms at home, safe storage practices were less common among those with a history of suicidal thoughts or behaviors who had firearms. Limitations of the study include self-reported information.

Is Blood Pressure Measured Outside of Clinic Associated with Cardiovascular Disease in African Americans?

JAMA Cardiology

EMBARGOED FOR RELEASE: 11 A.M. (ET), WEDNESDAY, AUGUST 14, 2019

Bottom Line: This observational study examined whether daytime and nighttime blood pressure (BP) levels measured outside a clinical setting are associated with cardiovascular disease (CVD) and risk of death. Blood pressure levels measured at a clinic may not accurately reflect levels that a person experiences at home, work or while asleep. Using data from the Jackson Heart Study, which is designed to identify CVD risk factors among African American individuals, this analysis included 1,034 adults who had average daytime and nighttime BP levels calculated based on measurements from a BP monitor on their arm that took readings every 20 minutes during a 24-hour period. During follow-up there were 113 CVD events (including coronary heart disease and stroke) and 194 deaths. The authors report that individuals with higher levels of daytime and nighttime systolic BP had an associated increased risk for CVD events and death, independent of BP levels measured in the clinic. The increase in CVD risk was larger among participants not taking BP medication. The findings suggest monitoring daytime and nighttime BP outside the clinic during a 24-hour period may help to identify African Americans at increased risk for CVD. A limitation of the study to consider is that 24-hour BP monitoring was performed only once among participants, and the researchers were unable to assess whether changes in daytime and nighttime BP during follow-up were associated with outcomes.

Bottom Line: Whether the experience of being a refugee increases the probability of developing a mental disorder such as schizophrenia was the focus of this study, a systematic review and meta-analysis that combined the results of nine studies involving 540,000 refugees in Denmark, Sweden, Norway and Canada. The relative risk of refugees developing nonaffective psychosis (which includes several mental disorders such as schizophrenia) was compared with the risk of natives of the host country and nonrefugee migrants there. Study authors report the refugee experience may be a risk factor in nonaffective psychosis in migrants. Limitations of the research include that with the exception of Canada, the studies included in the analysis were all from Scandinavian countries, which may limit the generalizability of the findings to other countries.

Bottom Line: Parents and teens find it difficult to talk about sex and alcohol, and this study finds that doctors can help. This randomized clinical trial evaluated whether interventions targeted at parents in primary care pediatric settings might improve communications between parents and their teens about sexual health and alcohol use. The interventions were selected because in previous research outside of clinic settings they have been shown to encourage teens to wait until they’re older to have sex, use protection if they do have sex, and reduce alcohol use. The study included 118 parent-adolescent pairs, with 38 pairs in a sexual health intervention, 40 pairs in an alcohol prevention intervention, and 40 pairs in a control group for comparison who received usual care. Parents in the interventions received coaching on key messages regarding sexual health and alcohol and were encouraged to engage in parent-adolescent communication about it within two weeks, at which time there was a follow-up call to parents from health coaches. Participants were surveyed four months later and study authors report an increased frequency of parent-teen communications about sexual health and alcohol use in the intervention groups compared to the control group. Results suggest that doctors have an opportunity to help parents and teens communicate about sex and alcohol in ways that will help young people make healthier choices about sexual behaviors and alcohol use. Limitations of the study include that it was conducted at a single site and parent-teen communications were self-reported.

Bottom Line: Rates of marijuana exposure cases in children and teens reported to a poison control center increased after Massachusetts legalized medical marijuana in 2012. From 2009 to 2016, there were 218 cannabis-related calls (a small portion of the calls to the poison center) about exposure in children and teens to age 19, with most of the calls coming from health care facilities. Teens ages 15 to 19 were involved in the highest number of cases followed by children to age 4. Exposures among teenagers were mostly classified as intentional whereas exposures among young children were unintentional. There were statistically significant increases in the number of exposures to edible products in both of these age groups. The rate for all cases involving cannabis for the four years before and the four years after medical marijuana legalization increased from 1.3 to 2.2 per 100,000. Limitations of the study include the small number of calls and self-reported marijuana exposures that may not have been verified by laboratory testing.

Bottom Line: Patterns of high blood pressure in midlife that extend to late life or high blood pressure in midlife followed by low blood pressure later in life was associated with increased risk for dementia compared to having normal blood pressure. This observational study included nearly 4,800 participants who had blood pressure measurements taken over 24 years at five visits plus a detailed neurocognitive evaluation during the fifth and a sixth visit, where dementia was assessed. There were 516 new cases of dementia diagnosed between the fifth and sixth visits. Study authors report that compared with maintaining normal blood pressure, an increased risk of dementia was associated with hypertension (greater than 140/90 mm Hg or use of antihypertensive medication) in midlife (age 54 to 63) that was sustained to late life and a pattern of hypertension in midlife and low blood pressure (less than 90/60 mm Hg) later life. Midlife hypertension followed by late-life low blood pressure also was associated with increased risk of mild cognitive impairment. Limitations of the study include that the findings may have been biased because of the increased likelihood that participants with higher blood pressure and poorer cognition during midlife dropped out of the study. Also, study participants were from Washington County, Maryland; Forsyth County, North Carolina; Jackson, Mississippi; and Minneapolis, so the results may not be generalizable to other areas.

Bottom Line: Whether exposure to outdoor air pollutants is associated with emphysema progression and change in lung function was the focus of this observational study. The study included 7,071 participants from the Multi-Ethnic Study of Atherosclerosis studies conducted in six U.S. metropolitan regions (New York; Los Angeles; Chicago; Baltimore; Winston-Salem, North Carolina; and St. Paul, Minnesota). Computed tomographic (CT) scans were used to assess changes in emphysema (measured for density as a percentage of lung pixels) and lung function testing was done. Levels of outdoor air pollutants (ozone, fine particulate matter, oxides of nitrogen and black carbon) at each participant’s home were estimated. Study authors report exposure to ambient air pollutants, especially ozone, was associated with increasing emphysema progression based on up to five repeated CT scans over 10 years. Ambient ozone exposure, but not the other pollutants, also was associated with decline in lung function. Limitations of the study include that outdoor air pollutant concentrations may not reflect everything about an individual’s air pollutant exposures, and outdoor concentrations don’t explain all of the variations in concentrations of pollutants indoors, where most people spend the majority of their time.

Bottom Line: Intensive blood pressure control among adults with high blood pressure was associated with a smaller increase in brain white matter lesions (a marker of small vessel disease and a risk factor for dementia) compared to standard blood pressure control, although the difference was small. Hypertension is a risk factor for developing white matter lesions. This analysis is a substudy of a randomized clinical of 449 patients with high blood pressure who had initial brain magnetic resonance imaging (MRI) and a follow-up MRI after four years. Researchers report intensive systolic blood pressure control (goal of less than 120 mm Hg) was associated with a smaller increase in white matter lesion volume compared with standard treatment (goal of less than 140 mm Hg). There also was a greater decrease in total brain volume, although the difference was small and the significance of this finding is unclear. Limitations of the study include the relatively short duration of the intervention and follow-up. Given the limited size of this study, it’s also not possible to correlate changes in brain structure with dementia occurrence.

Study Examines Gluten Consumption in Childhood, Celiac Disease Risk in Genetically At-Risk Kids

JAMA

EMBARGOED FOR RELEASE: 11 A.M. (ET), TUESDAY, AUGUST 13, 2019

Bottom Line: Consuming more gluten during the first five years of life was associated with increased risk of celiac disease and celiac disease autoimmunity (the presence of antibodies in the blood) among genetically predisposed children. It remains unclear whether the amount of gluten consumed can trigger celiac disease. This observational study included 6,605 children born between 2004 and 2010 in Finland, Germany, Sweden and the United States who had a genetic predisposition for celiac disease. Gluten intake was estimated from food records collected at ages 6, 9, and 12 months and then biannually until the age of 5. Of the 6,605 children, 18% developed celiac disease autoimmunity and 7% developed celiac disease. The incidence of both outcomes peaked at 2 to 3 years old. The authors report that for every 1-gram per day increase in gluten consumption there was an associated higher risk of celiac disease and celiac disease autoimmunity. If gluten intake was one gram per day higher than the average at age 2 (corresponding to a half slice of white bread), the absolute risk differences for celiac disease autoimmunity and celiac disease were 6% and 7% higher, respectively, by age 3. A limitation of the study is the uncertainty of the accuracy of the reported gluten intake. The authors suggest a randomized clinical trial be done of different amounts of gluten during early childhood in genetically at-risk children.

Bottom Line: An analysis of claims data for privately insured patients suggests out-of-network billing for inpatient admissions and emergency department (ED) visits to in-network hospitals has increased along with the patient financial liability associated with it. This study included 5.4 million inpatient admissions and nearly 13.6 million ED visits to in-network hospitals between 2010-2016. Of all the ED visits, 39.1% generated an out-of-network bill and 37% of all the inpatient admissions resulted in an out-of-network bill. The percentage of ED visits with an out-of-network bill increased from 32.3% to 42.8% during the study period and the percentage of inpatient admissions with an out-of-network bill increased from 26.3% to 42% during that same time.  The potential patient financial responsibility associated with out-of-network bills increased too, from an average $220 to $628 for ED visits and from an average $804 to $2,040 for inpatient admissions. A common example of out-of-network billing was ambulance transport. This study has some limitations, including no information on what patients actually paid to settle out-of-network bills. Researchers suggest their findings support strengthening legislative protections against the surprise medical bills associated with out-of-network billing.

Every Wednesday and Friday, the journal publishes peer-reviewed clinical research and commentary in more than 40 medical and health subject areas. Every article is free online from the day of publication.

 

Bottom Line: This observational study looked at whether extreme heat is associated with increased risk of hospitalization or death among the vulnerable population of patients with end-stage renal disease (ESRD). The study included 7,445 patients with ESRD who underwent long-term hemodialysis treatment at clinics in Boston, Philadelphia or New York from 2001 to 2012. During that time, 2,953 of the patients died. Researchers used historical weather data to identify extreme heat days and investigated if exposures to such extreme heat days increased risk of hospitalizations and deaths among the patients. Extreme heat was associated with increased risk of same-day hospital admission and same-day death, with the risk of death greater among patients living with congestive heart failure, chronic obstructive pulmonary disease or diabetes. Risk varied between cities and by race/ethnicity. Limitations of the study include a lack of data to verify indoor conditions for patients and the study didn’t account for multiple-day heat waves, which could present a more severe threat for patients with ESRD.

Bottom Line: An examination of a combined 28 years of data finds similarities in the characteristics and illnesses of patients requesting medical aid in dying in Oregon and Washington. The study included 3,368 prescriptions written for medical aid in dying, with 2,558 patients dying by lethal ingestion of medication, in the two states from 1998 to 2017 in Oregon and from 2009 to 2017 in Washington. Most of the patients were insured, non-Hispanic white individuals with some level of college education, 65 or older, and diagnosed with cancer. Loss of autonomy, impaired quality of life and loss of dignity were the most common reasons for pursuing medical aid in dying. Limitations of the study include physicians, not patients, providing the underlying reasons for requesting medical aid in dying as part of a follow-up questionnaire.

Bottom Line: National private insurance claims data were used to examine opioid prescribing patterns in children after tonsillectomy and return visits for complications. Opioids are commonly used after tonsillectomy, although American Academy of Otolaryngology clinical practice guidelines recommend nonopioids such as NSAIDs. This analysis included 2016 and 2017 claims data coded for tonsillectomy for nearly 16,000 children; nearly 60 percent of whom had one or more prescription drug claims for opioids between seven days before to one day after tonsillectomy. Having one or more prescription fills wasn’t associated with return visits for pain or dehydration or bleeding compared with children not using opioids but it was associated with increased risk of return visits for constipation. The study authors suggest reducing opioid prescribing to children after tonsillectomy may be possible without increasing risk of complications. The study has several limitations, including that children may not use opioids even when prescriptions are filled.

Every Wednesday and Friday, the journal publishes peer-reviewed clinical research and commentary in more than 40 medical and health subject areas. Every article is free online from the day of publication.

 

Bottom Line: A nationwide population-based study in Taiwan suggests attention-deficit/hyperactivity disorder (ADHD) may be associated with a higher risk of death from injury causes, including suicide, unintentional injury and homicide. Although the risk of suicide-related death was higher in patients with ADHD than in those without, the absolute risk of death was low and suicide deaths were rare, with natural-cause deaths and unintentional injury deaths accounting for a higher number of deaths than suicide in the group of patients with ADHD. This observational study used registry data and included nearly 276,000 patients (ranging in age from 4 to 44) first diagnosed with ADHD between 2000 and 2012 and nearly 2 million individuals without ADHD for comparison. There was no increased risk of natural-cause death between the two groups. More research is needed to understand the causes of injury deaths in patients with ADHD and identify ways to mitigate them. Limitations of the study include the findings may not generalizable to others, including people with ADHD who aren’t diagnosed and those in other international settings. The study also couldn’t analyze the effects of ADHD medications and other potential mitigating factors, such as family history and psychosocial stress.

Bottom Line: A population-based study using data from the National Health Insurance Research Database of Taiwan suggests hearing loss is associated with risk of dementia. The study included 8,135 patients with newly diagnosed hearing loss and an equal number of individuals without hearing loss for comparison. Among the 16,270 study participants, 1,868 developed dementia. Patients with hearing loss had a higher risk of dementia, especially those 45 to 64 years old. Six coexisting conditions also were associated with dementia risk in the present study. The authors caution causal inferences cannot be drawn from their findings.

Bottom Line: This observational study looked at how green space is associated with mental health. Some research has suggested living near more green space may be associated with benefits. This analysis included nearly 47,000 city-dwelling adults in Australia and examined how living near different kinds of green space (including tree canopy, grass and low-lying vegetation) may be associated with risk of psychological distress, self-reported physician-diagnosed depression or anxiety, and fair to poor self-reported general health. The three outcomes were examined at baseline and  follow-up about six years later. The authors report exposure to more tree canopy was associated with a lower likelihood of psychological distress and better self-rated general health. No green space indicator was associated with depression or anxiety. Exposure to low-lying vegetation wasn’t consistently associated with any outcome. Exposure to more grass was associated with a higher likelihood of reporting fair to poor general health and prevalent psychological distress. Limitations of the study include self-reported health outcomes and green space availability that may have decreased in some areas over time, which may mean the results underestimate the associations.

Bottom Line: The proportion of U.S. adults adhering to the “Physical Activity Guidelines for Americans” from the U.S. Department of Health and Human Services didn’t significantly improve between 2007 and 2016 but time spent sitting increased. The first edition of the federal guidelines recommending types and duration of physical activity were released in 2008 and updated in 2018, including a recommendation to spend less time sitting. This study used nationally representative survey data from about 27,000 adults to examine adherence to the recommendations for aerobic activity, as well as sedentary behavior from 2007 to 2016. Study authors report 65.2% met the guidelines for aerobic activity in 2015-2016, compared with 63.2% in 2007-2008, while time spent sitting increased from 5.7 hours per day in 2007-2008 to 6.4 hours per day in 2015-2016. The proportion of people not meeting the recommendations for aerobic activity and sitting more than six hours a day increased from 16.1% to 18.8% during this same period. A limitation of the study is that the information on physical activity and sitting time was self-reported.

Risk of Death Among Postmenopausal Women With Normal Weight and High Abdominal Fat

Every Wednesday and Friday, the journal publishes peer-reviewed clinical research and commentary in more than 40 medical and health subject areas. Every article is free online from the day of publication.

 

Bottom Line: Postmenopausal women with normal weight (body mass index 18.5 to 24.9) and central obesity (waist circumference greater than 88 cm) are at higher risk of death compared to women with normal weight and no central obesity. Obesity prevention commonly focuses on BMI, which can’t distinguish body shape or body fat distribution. The high abdominal fat distribution that is central obesity is common in the general population. This observational study examined the associations of normal-weight central obesity with risk of death using data from nearly 157,000 postmenopausal women enrolled in the Women’s Health Initiative between 1993 and 1998. Normal-weight central obesity in women was associated with an increased risk of death that was comparable to that of women with obesity (BMI equal to or greater than 30) and central obesity. Limitations of the study include its focus on postmenopausal women so the findings may not be broadly generalizable to younger women or men. The study authors suggest that normal-weight central obesity in women may be an underrecognized high-risk subpopulation and that the prevention and control of central obesity should be included in clinical and public health guidelines, even for individuals of normal weight.

Compared with individuals without cancer, there was a statistically significant association between BRCA2 mutations and risk of non-Hodgkin lymphoma but not Hodgkin lymphoma. The findings support including childhood non-Hodgkin lymphoma in the spectrum of cancers associated with BRCA2 mutations.

Bottom Line: This database analysis looked at whether U.S. News & World Report top-ranked hospitals for gastroenterology and gastrointestinal surgery were associated with improved patient outcomes for common advanced laparoscopic abdominal operations, including bariatric, colorectal and hiatal hernia procedures. The study included nearly 52,000 abdominal operations performed at 351 academic centers and their affiliated hospitals in the United States in 2017; 31.4% of the procedures were performed at 41 top-ranked hospitals and 68.6% of procedures were done at 310 nonranked hospitals. The annual volume of procedures was three times higher at top-ranked hospitals but there were no significant differences in serious complications or in-hospital death between top-ranked and nonranked hospitals. However, advanced laparoscopic abdominal operations at top-ranked hospitals cost more on average and were associated with longer average hospital stays. This study has several limitations associated with the use of database information such as coding errors and selection bias.

Bottom Line: The incidence of colorectal cancer among younger adults increased in recent years in this analysis of data from Canadian national cancer registries that included about 688,000 new colorectal cancers diagnosed over more than 40 years. Among men younger than 50, there was an average annual percentage change of 3.47% from 2006 to 2015. Among women younger than 50, there was an average annual percentage change of 4.45% from 2010 to 2015. Because the study used registry data, authors didn’t have access to any demographic information other than age so they were unable to identify what other factors may be associated with the increases. Potential reasons to explain the increases are not well understood and the authors suggest that be investigated before any change in screening guidelines is pursued.

Bottom Line: This study (called a systematic review and meta-analysis) combined the results 31 randomized clinical trials with 12,464 adolescent participants to examine whether parent-based sexual health interventions were associated with three main outcomes: delayed sexual activity, improved condom use and parent-child sexual communication. The findings were generally modest but across the studies there was a significant association of parent-based interventions with improved condom use and parent-child sexual communication but no significant differences for delaying adolescents’ sexual activity. The current study has several limitations, including variation in how outcomes were measured in the studies pooled for this analysis.

Bottom Line: Symptoms of physician burnout appear to be associated with greater bias toward black people in this study of nearly 3,400 second-year resident physicians in the United States who identified as nonblack. Survey data from questionnaires that were part of another study were used. About 45% of physician residents had symptoms of burnout. Explicit bias was measured on a “feeling thermometer” with the lowest score meaning cold or unfavorable toward black people and the highest score meaning warm or favorable; implict bias was measured on a test that involved sorting pictures of white and black people and words to describe them including “good” and “bad.” Study authors suggest symptoms of burnout may be factors in care disparities. However, this observational study cannot determine if the suggested association between symptoms of burnout and bias toward black people is causal and the magnitude of the observed association was small to medium.

Bottom Line: Major league baseball (MLB) players had lower death rates overall and from many underlying causes of death compared with men in the general U.S. population, differences that could be associated in part with the physical fitness required for their jobs. This research letter reports on an analysis of mortality rates among 10,451 baseball players who debuted in the MLB from 1906 through 2006, including differences in mortality rates by position and career length. Having a longer playing career was associated with a lower rate of cardiovascular-related death and an increased rate of cancer deaths. Limitations of the study include an inability to account for physical activity, head injuries and other environmental or genetic factors.

Bottom Line: This study (called a systematic review and meta-analysis) combined the results of nine studies and examined the association between adherence to plant-based eating habits and risk of type 2 diabetes in adults. The analysis included 307,099 adults with 23,544 cases of type 2 diabetes. The authors report higher adherence to plant-based eating habits was associated with lower risk of type 2 diabetes, especially when only healthy plant-based foods, such as fruits, vegetables, whole grains, legumes and nuts, were included in the definition of plant-based. Limitations include that all of the studies analyzed were observational and dietary habits were self-reported.

Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends screening for hepatitis B virus (HBV) infection in pregnant women at their first prenatal visit. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this statement is a reaffirmation of its 2009 recommendation. Screening for HBV infection during pregnancy identifies infants who are at risk of acquiring this infection from their mothers before or after birth. Children infected with HBV during infancy or childhood are more likely to develop chronic infection.

Bottom Line: Imaging shows differences in the brains of U.S. government personnel who were potentially exposed to unusual audible and sensory phenomena (sound, pressure or vibration) while serving in Cuba when compared with brain images from a group of healthy individuals without such exposure, although the clinical importance of these brain differences is uncertain. A preliminary report published by JAMA in 2018 described neurological signs and symptoms experienced by some of these government workers. In this study, advanced magnetic resonance imaging (MRI) of the brain was done for 40 workers and 48 healthy individuals who were demographically similar for comparison to analyze three components (brain volume, microstructural tissue measures, and functional connectivity). Study authors report differences in whole brain white matter volume, regional gray and white matter volumes, cerebellar tissue microstructural integrity, and functional connectivity in the auditory and visuospatial subnetworks of the brain but not in the executive control subnetwork. There also were no significant differences in total whole brain gray matter volume. The findings suggest there may be differences in brain structure in several brain regions and in some functional brain networks. The current study has several limitations including that it cannot determine if the differences among patients are because of individual differences or differences in the level and degree of exposure to the reported sound, pressure or vibrations.

Bottom Line: A national population-based study suggests the 2016 U.S. presidential election may have been associated with an increase in preterm births among Latina women in the United States. The design of the study is used to evaluate whether policies or other population-level changes interrupt a trend in an outcome. Using data on birth counts from 2009 through July 2017 from the Centers for Disease Control and Prevention, researchers compared preterm births (less than 37 weeks) to Latina women after the 2016 presidential election with the number expected had the election not taken place. Among nearly 32.9 million live births recorded during the study period, 11% of males and 9.6% of female births to Latina women were preterm compared with 10.2% and 9.3%, respectively, to other women. In the nine-month period beginning in November 2016, an additional 1,342 male and 995 female preterm births to Latina women were found above the expected number of preterm births, which is about 3.2% to 3.6% more. This study cannot identify the reasons behind the findings and other limitations of the study include an inability to differentiate between native and nonnative Latina women in the U.S. The authors suggest future research look at the association of anti-immigration policies with population health.

Bottom Line: An observational study of pregnant women in Northern California suggests marijuana use before and during pregnancy has increased over time. The study of nearly 277,000 women in Kaiser Permanente Northern California included 367,403 pregnancies from 2009 to 2017. The women reported marijuana use on questionnaires as part of standard prenatal care. The authors report marijuana use in the year before pregnancy increased from 6.8% of women in 2009 to 12.5% in 2017, and marijuana use during pregnancy increased from 1.95% to 3.38%. Daily use of marijuana in the year before pregnancy increased from 1.17% in 2009 to 3.05% in 2017, and daily use during pregnancy increased from 0.28% to 0.69%. A limitation of the study is that the results may not be generalizable to women outside of California or those without access to health care.
