Is your testosterone in the sweet spot for heart health? ⚖️ New research suggests both low and high levels may raise the risk of atrial fibrillation. https://www.news-medical.net/news/20260902/Too-little-or-too-much-testosterone-may-matter-for-heart-rhythm.aspx

A review of clinical trials, observational studies, genetic analyses, and mechanistic research suggests that atrial fibrillation risk may follow a U-shaped relationship with testosterone, increasing at both low and high levels. Evidence on testosterone replacement therapy remains mixed, with researc...

A new AI learned from cardiologists' notes and now diagnoses heart issues from ECGs using up to 90% less labeled data. 🩺🤖 Can machines learn the way doctors do? https://www.news-medical.net/news/20260902/AI-learned-from-cardiologistse28099-notes-and-needed-far-less-labeled-ECG-data.aspx

By teaching an AI system to connect raw heart signals with the clinical insights contained in cardiologists’ reports, researchers tested whether routine ECGs could reveal more with far fewer labeled examples.

Menopause starts changing the gut years before periods stop. 🧬 New research links early shifts in blood biomarkers to changes in gut barrier integrity and inflammation. https://www.news-medical.net/news/20260902/Menopause-may-start-changing-the-gut-years-before-periods-stop.aspx

A longitudinal study of 964 women found that blood markers of gut epithelial barrier dysfunction and microbial product translocation began to rise around 2 to 2.5 years before the final menstrual period and remained elevated after menopause. The findings suggest that changes in gut barrier integrity...

Can the same drugs helping diabetes and obesity fight addiction, too? 🧬 Early trials hint GLP-1 meds might reduce cravings and substance use. See why researchers are intrigued: https://www.news-medical.net/news/20260902/Why-addiction-researchers-are-paying-closer-attention-to-GLP-1-drugs.aspx

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 auth...

🍽️ Your weekend meal schedule may impact heart health more than you think. Irregular eating times between weekdays and weekends linked to higher cardiovascular risk in men. https://www.news-medical.net/news/20260902/Your-weekend-meal-schedule-may-matter-more-than-you-think.aspx

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 we...

Europe's mosquito challenge isn't what you'd expect: the cold-loving Aedes koreicus is spreading fast and could thrive where others can't. Why does it matter, and what's next for surveillance? 🦟❄️

https://www.news-medical.net/news/20260902/Europe-has-a-new-mosquito-problem-but-it-may-not-be-the-one-you-think.aspx

A scoping review of 91 studies, combined with a workshop involving 41 experts from six European countries, mapped the spread, biology, surveillance challenges, and potential disease relevance of the invasive mosquito Aedes koreicus. The researchers identified major gaps in species identification, ve...

☕️🧬 Does your DNA change how coffee affects Parkinson’s risk? A massive study finds your caffeine metabolism - and your s*x - could flip the script. https://www.news-medical.net/news/20260902/Coffeee28099s-link-to-Parkinsone28099s-risk-may-depend-on-how-your-body-handles-caffeine.aspx

In 435,551 UK Biobank participants followed for a median of 15.7 years, overall coffee consumption was not associated with Parkinson’s disease risk, but the relationship differed significantly according to CYP1A2 genotype. Lower risk was observed with low-to-moderate coffee intake among fast-metab...

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic declin...

Snakebite deaths and injuries may be far more widespread than we thought. New global modeling highlights hidden tolls, especially in rural and low-income areas. 🐍🌍
https://www.news-medical.net/news/20260901/The-global-toll-of-snakebite-may-be-much-bigger-than-we-thought.aspx

A global literature review and geostatistical modeling study estimated the burden of snake envenoming and deaths across countries, accounting for differences in surveillance, underreporting, socioeconomic conditions, and environmental factors. The analysis highlights major gaps in epidemiological da...

New study links higher intake of flavorings, colors, and sweeteners in ultra-processed foods to increased depression risk 🍬🧠 https://www.news-medical.net/news/20260901/Flavorings-colors-and-sweeteners-emerge-as-UPF-markers-linked-to-depression-risk.aspx

A prospective UK Biobank study of 171,818 adults found that greater estimated exposure to foods containing flavorings, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression over 10.7 years. The findings suggest that specific markers, rather than ul...
