Why addiction researchers are paying closer attention to GLP-1 drugs

A Journal of Clinical Investigation Viewpoint highlights growing evidence that GLP-1 receptor agonists, particularly semaglutide, may reduce alcohol consumption and some other substance-related outcomes by acting on brain systems involved in reward, motivation, stress, and emotion. However, the authors caution that efficacy for substance use disorders is not yet firmly established and call for further research into optimal dosing, treatment duration, patient selection, mechanisms, and effects across different addictions.

Your weekend meal schedule may matter more than you think

In a prospective analysis of 104,806 adults from the NutriNet-Santé cohort, greater differences in meal timing between weekdays and weekends were associated with higher risks of cardiovascular disease and coronary heart disease in men over a median 8.1 years. The associations were strongest when weekend eating shifted earlier, while delayed weekend eating was linked specifically to coronary heart disease, with no association detected for cerebrovascular disease.

Post-surgery immunotherapy may not benefit specific lung cancer patients

A new real-world observational study has found that adding adjuvant immunotherapy after surgery does not significantly improve survival outcomes in patients with resectable non-small cell lung cancer (NSCLC) who have already achieved a pathological complete response (pCR) following neoadjuvant chemoimmunotherapy.

Semaglutide extends lifespan and slows physiological aging in healthy mice

A National Institutes of Health (NIH)-funded study has shown that the GLP-1 drug semaglutide extended lifespan in older, healthy mice by tempering the detrimental effects of aging.

Plant-based fats improve long-term survival for prostate cancer patients

Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health.

Genetic marker links popular seizure drug to life-threatening reaction

A genetic marker already used to flag risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine - and it is missing from the gene panels clinicians order before prescribing the drug, Vanderbilt Health-led researchers report Sept. 2 in JAMA Network Open.
