About The Study: The results of this randomized clinical trial showed that a 15-day course of nirmatrelvir-ritonavir in a population of patients with postacute sequelae of SARS-CoV-2 infection (PASC) was generally safe but did not demonstrate a significant benefit for improving select PASC symptoms in a mostly vaccinated cohort with protracted symptom duration. Further studies are needed to determine the role of antivirals in the treatment of PASC.

About The Study: This study found that higher rates of incarceration were associated with increased rates of firearm homicides among Black communities alone; this association was found to be mediated partially through the density of single-parent households in these areas, suggesting that social disorganization resulting from mass incarceration may perpetuate firearm homicides. Targeted policies addressing mass incarceration and the disparities therein may be a means of reducing urban firearm homicides.

About The Study: This quality improvement analysis of clinical trials for metastatic breast, lung, colon, pancreatic, and prostate cancers found that a large proportion of the U.S. population lived within 30 miles of a clinical trial site. This finding suggests that while many clinical trials are available, they are not evenly distributed across the country and may not be accessible to all individuals, particularly racial and ethnic minority individuals. This disparity in access to clinical trials raises important questions about equity and fairness in the distribution of health care resources and opportunities for treatment.

About The Study: Ivonescimab plus chemotherapy significantly improved progression-free survival with tolerable safety profile in patients with non–small cell lung cancer who previously underwent EGFR tyrosine kinase inhibitor (EGFR-TKI) treatment and may offer a new treatment option for patients with TKI resistance. 

 

Quote from corresponding author Li Zhang, M.D.:

“For patients with non-small cell lung cancer whose illness has progressed while receiving EGFR tyrosine kinase inhibitor (EGFR-TKI) therapy, especially the third generation TKIs, optimal treatment options remain limited.

“This randomized, placebo-controlled phase 3 study demonstrated ivonescimab plus chemotherapy significantly improved progression-free survival (7.1 vs 4.8 months) compared with chemotherapy alone in TKI-treated non-small cell lung cancer.

“Based on the results of this study, ivonescimab has been approved in China as a new treatment option for those patients. An international multi-center study of this treatment regimen is ongoing.”

Stepped Palliative Care for Patients With Advanced Lung Cancer

JAMA

EMBARGOED FOR RELEASE: 9 A.M. ET, SUNDAY, JUNE 2, 2024

Media advisory: The full study is linked to this news release. This study is being presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting.

About The Study: A stepped-care model, with palliative care visits occurring only at key points in patients’ cancer trajectories and using a decrement in quality of life to trigger more intensive palliative care exposure, resulted in fewer palliative care visits without diminishing the benefits for patients’ quality of life. While stepped palliative care was associated with fewer days in hospice, it is a more scalable way to deliver early palliative care to enhance patient-reported outcomes. 

 

Quote from corresponding author Jennifer S. Temel, M.D.:

“This study demonstrates that early palliative care can be effectively tailored to a patient’s cancer and care needs to maximize their quality of life while utilizing fewer palliative care resources. Implementing this patient-centered approach to delivering early palliative care will allow more patients to access essential early palliative care services.

“These findings are especially salient as patients with advanced cancer are now living longer while being treated with life-long cancer therapies, so a tailored palliative care model enables greater dissemination of palliative care services while ensuring patients receive the care they need when they need it.

“This research continues to grow the evidence base that early palliative care is a necessary and integral component of cancer care for patients diagnosed with advanced cancer and provides data on how to increase the number of patients who can access this essential service.”

USPSTF Recommendation Statement on Interventions to Prevent Falls in Community-Dwelling Older Adults

JAMA

EMBARGOED FOR RELEASE: 10:30 A.M. (ET), TUESDAY, JUNE 4, 2024

Media advisory: To contact the U.S. Preventive Services Task Force, email the Media Coordinator at Newsroom@USPSTF.net or call 301-951-9203. The full report and related articles are linked to this news release.

Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends exercise interventions to prevent falls in community-dwelling adults 65 years or older who are at increased risk for falls. The USPSTF recommends that clinicians individualize the decision to offer multifactorial interventions to prevent falls to community-dwelling adults 65 years or older who are at increased risk for falls. Existing evidence indicates that the overall net benefit of routinely offering multifactorial interventions to prevent falls is small. When determining whether this service is appropriate for an individual, patients and clinicians should consider the balance of benefits and harms based on the circumstances of prior falls, presence of comorbid medical conditions, and the patient’s values and preferences. Falls are the leading cause of injury-related morbidity and mortality among older adults in the U.S. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this recommendation replaces the 2018 recommendation.

About The Study: In this serial cross-sectional study including a national sample of U.S. college students, researchers found a notable increase in the prevalence of posttraumatic stress disorder (PTSD) and acute stress disorder, rising by 4.1 percentage points and 0.5 percentage points from 2017 to 2022, respectively. These trends highlight the escalating mental health challenges among college students, which is consistent with recent research reporting a surge in psychiatric diagnoses. Factors contributing to this rise may include pandemic-related stressors (e.g., loss of loved ones) and the effect of traumatic events (e.g., campus shootings, racial trauma).

Long-Term Outcomes in Patients Using Protocol-Directed Active Surveillance for Prostate Cancer

About The Study: In this study, 10 years after diagnosis, 49% of men remained free of progression or treatment, less than 2% developed metastatic disease, and less than 1% died of their disease. Later progression and treatment during surveillance were not associated with worse outcomes. These results demonstrate active surveillance as an effective management strategy for patients diagnosed with favorable-risk prostate cancer. 

 

Quote from corresponding author Lisa F. Newcomb, Ph.D.:

“Our study showed that using active surveillance that includes regular PSA exams and prostate biopsies is a safe and effective management strategy for favorable risk prostate cancer.

“An important finding was that adverse outcomes such as recurrence or metastasis do not seem worse in people treated after several years of surveillance versus one year of surveillance, alleviating concern about losing a window of curability.

“We hope that this study encourages the national acceptance of active surveillance instead of immediate treatment for prostate cancer.”

About The Study: The results of this study suggest that the sweetened beverage tax in Seattle may be associated with a small but reasonable reduction in body mass index (BMI) among children living in Seattle compared with children living in nearby nontaxed areas who were receiving care within the same health care systems. Taken together with existing studies in the U.S., these results suggest that sweetened beverage taxes may be an effective policy for improving children’s BMI. Future research should test this association using longitudinal data in other U.S. cities with sweetened beverage taxes.

About The Study: In this national cross-sectional study of privately insured U.S. families, inflation-adjusted health care spending increased from 2007 to 2019, largely owing to increasing contributions to premiums. Annual financial medical burden increased significantly, both overall and among low-income and higher-income families. Mean financial medical burden was more than 26% of postsubsistence income for low-income families, compared with approximately 6% for higher-income families.

There was a degree of specificity in terms of pollutant-timing-outcome associations. Interventions to reduce air and noise pollution exposure (e.g., clean air zones) could potentially improve population mental health. Replication using quasi-experimental designs is now needed to shed further light on the underlying causes of these associations.

About The Study: The findings of this matched cohort study suggest that women with premenstrual disorders are not at increased risk of early death overall. However, the risk was elevated among young women and for death by suicide. This supports the importance of careful follow-up for young patients and highlights the need to develop suicide prevention strategies for all women with premenstrual disorders.

About The Study: In this cohort study of living kidney donors and nondonors with the same follow-up schedule, the risks of hypertension and albuminuria were not significantly different. After the initial drop in estimated glomerular filtration rate (eGFR) from nephrectomy, donors had a slower mean rate of eGFR decline than nondonors but were more likely to have an eGFR between 30 and 60 mL/min/1.73 m2 at least once in follow-up.

US Public Health Preparedness and Response to Highly Pathogenic Avian Influenza A(H5N1) Viruses

EMBARGOED FOR RELEASE: 12 P.M. ET, TUESDAY, MAY 21, 2024

Media advisory: The full study is linked to this news release.

Embed this link to provide your readers free access to the full-text article This link will be live at the embargo time https://jamanetwork.com/journals/jama/fullarticle/10.1001/jama.2024.10116?guestAccessKey=97235608-3017-4f2a-b30c-8486923bab25&utm_source=For_The_Media&utm_medium=referral&utm_campaign=ftm_links&utm_content=tfl&utm_term=052124

 

About The Study: Public health authorities in nearly all states and territories surveyed reported the ability to monitor and test persons exposed to highly pathogenic avian influenza (HPAI) A(H5N1) virus. However, jurisdictions varied in their capacity to monitor exposed persons, in recommendations for use of antivirals, and in potential use of H5N1 vaccines, if available, among first responders. 

 

Quote from co-author Tim Uyeki, M.D., M.P.H., M.P.P.:

 

“Public and animal health experts and agencies have been preparing for avian influenza outbreaks for 20 years. We have invested in our ability to mitigate risk by testing, preventing, and treating it.

 

“The challenges reported in monitoring exposed persons and differences in antiviral recommendations highlight a need to continue to strengthen and standardize public health preparedness and response to HPAI A(H5N1) viruses in the United States, particularly if additional animal-to-human transmission events are reported. It’s important that as the situation develops, public health agencies and authorities continue to work together to guide process improvements to ensure preparedness and consistency in response to future exposures.”
