Researchers train AI to detect diabetes and assign four diagnostic labels

Researchers developed a two-stage machine learning framework that detected diabetes and classified records as prediabetes, type 1, type 2, or type 3c diabetes using two public datasets. XGBoost showed strong internal performance, but inconsistent model rankings, non-standard variables, and the absence of external clinical validation limit immediate use.

Deramiocel cell therapy slows muscle and heart damage in advanced DMD

A cell therapy called deramiocel could slow muscle weakening in boys and young men with advanced Duchenne muscular dystrophy (DMD), and may also slow heart damage in those who already have heart muscle disease, a phase 3 clinical trial published in The Lancet has found.

Premature menopause linked to higher risk of developing hypertension

Women who reach menopause before age 40 face a meaningfully higher risk of developing high blood pressure than those who go through menopause after age 45, according to a new study of more than 107,000 women.

New study reveals massive gap in American blood pressure care

Nearly 23 million Americans with blood pressure 130/80 mm Hg or higher may be eligible for blood-pressure-lowering medications based on the 2025 American Heart Association/American College of Cardiology guideline, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed scientific journal of the American Heart Association.

Remdesivir protects kidney and heart health in transplant recipients

Adults with kidney transplants who were treated for COVID-19 with the antiviral remdesivir within a week of COVID-19 diagnosis and who received at least three consecutive days of therapy were less likely than kidney transplant recipients who did not receive the antiviral to experience cardiovascular or kidney problems up to a year later, according to findings from a target trial emulation study that published in JAMA Network Open.

Review finds blueberry and grape polyphenols may improve vascular health

A review of 37 publications found that grape- and blueberry-derived polyphenols were associated with modest improvements in cardiovascular risk markers, particularly endothelial function. However, most studies were small or short-term, frequently tested concentrated products, and measured biomarkers rather than cardiovascular events.

Blood tests improve Alzheimer's detection in Down syndrome patients

New blood tests that detect early changes associated with Alzheimer's disease are making diagnosis easier and accessible to more patients, since they are less invasive than the brain scans or spinal taps typically used for a definitive diagnosis.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.
