Healthcare barriers impact survival rates for adult congenital heart disease

People with congenital heart disease living in states with low household incomes and limited access to health insurance and the specialized care they need may be more likely to become disabled or die from congenital heart disease, according to new, independent research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

GLP-1 receptor activation linked to lower depression and bipolar disorder odds

Genetic analyses linked BMI-related GLP-1 receptor activation to better mental well-being and lower odds of major depressive disorder and bipolar disorder. The findings do not prove that GLP-1 receptor agonist drugs treat psychiatric conditions, and randomized clinical trials are still needed.

Breast and prostate cancer survival worsens with metabolic syndrome

A SEER-Medicare analysis of more than 200,000 adults aged 66 and older found that metabolic syndrome was associated with about twice the adjusted hazard of death from any cause after breast or prostate cancer. The condition was also linked to higher cancer-specific, cardiovascular-specific, and liver-failure-specific mortality, although the observational design prevents causal conclusions.

Cell death crosstalk network drives acute respiratory distress syndrome

Acute respiratory distress syndrome (ARDS) remains one of the deadliest complications of severe infections, sepsis, trauma, and viral pneumonia, yet decades of research have produced few targeted therapies capable of improving patient outcomes.

AI errors shaped doctors’ judgments despite contradictory evidence

Two experiments involving 223 self-reported physicians found that incorrect AI patient classifications strongly influenced treatment decisions and effectiveness judgments. Even when patient outcomes contradicted the AI, participants struggled to revise their conclusions and, in one experiment, judged a completely ineffective treatment as beneficial.

Study links GLP-1 treatment to fewer alcohol drinking days

Current GLP-1 receptor agonist prescriptions were associated with modestly lower AUDIT-C scores in a large, diverse US cohort. The difference appeared to reflect less frequent drinking rather than fewer drinks per occasion or fewer binge-drinking episodes.

Cohort study investigates the efficacy of traditional Chinese medicine for post-COVID-19 syndrome

Due to the lack of specific Western medicine therapies for post-coronavirus disease 2019 (COVID-19) syndrome in clinical practice, this study aimed to investigate the efficacy of traditional Chinese medicine (TCM) for post-COVID-19 syndrome using a cohort study design and to explore its clinical value in alleviating patients' symptoms and improving clinical outcomes.

Phelan-McDermid syndrome may be more common than previously believed

New research, led by scientists from the Seaver Autism Center for Research and Treatment at Mount Sinai and published June 28 in Autism Research, has estimated that Phelan-McDermid syndrome (PMS) affects approximately 1 in 7,300 people, making it dramatically more common than previous estimates suggested.
