Doctors urge smarter use of universal donor blood amid shortages

As blood banks across the U.S. report dangerously low supplies of O-negative blood (red blood cells) - commonly called the "universal donor" - anesthesiologists are calling for increased donation and changes in how hospitals use the "universal donor" blood type, according to a new Innovation in Practice article published online in Anesthesiology Open, an official journal of the American Society of Anesthesiologists (ASA).

Expanded access to rotational atherectomy maintains safety in PCI procedures

Percutaneous coronary intervention (PCI) is a standard treatment for significant coronary artery disease. Cardiologists use a catheter to place a stent that opens up the blockage and restores blood flow to the heart.

How long should you take GLP-1 drugs? Study links longer use to lower heart risk

Continuous use of GLP-1 receptor agonists in adults with type 2 diabetes was associated with a lower risk of major cardiovascular events compared with sulfonylureas, with benefits increasing over time. Discontinuation or interruption was associated with a progressive loss of this protective effect, with risks approaching those of comparator therapy.

A healthier thymus predicts longer life and lower cancer and heart disease risk in adults

Imaging-based analysis of over 27,000 adults shows that better thymic health is strongly associated with lower all-cause mortality, reduced lung cancer risk, and improved cardiovascular outcomes. The findings suggest the thymus remains biologically relevant in adulthood, linking immune aging, inflammation, and chronic disease risk, although causality cannot be established.

Genetic risk for Alzheimer's disease may be modified by higher meat intake

Older people with a genetic risk of Alzheimer's disease did not experience the expected increase in cognitive decline and dementia risk if they consumed relatively large amounts of meat.

New compound targets the neuronal epigenome to treat Alzheimer's disease

A team from the University of Barcelona has designed and validated in animal models an innovative compound with a pioneering mechanism of action for the treatment of Alzheimer's disease.

Young women face rising mortality rates from high blood pressure

Nearly 1 in 2 Americans has high blood pressure—sometimes called the "silent killer" because it harms the heart and blood vessels—but many people don't know they have it.

Early morning workouts may improve cardiometabolic health

People who regularly exercised early in the morning were significantly less likely to have coronary artery disease, high blood pressure, Type 2 diabetes or obesity compared with people who exercised later in the day, according to a study being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

New tool helps thousands achieve better blood pressure control

A blood pressure program adopted across the University of California's six academic medical centers has effectively lowered hypertension and prevented serious disease or death for thousands of patients, according to a new study led by UC San Francisco.

Menopause may raise women’s Alzheimer risk earlier than doctors once thought

This review argues that women’s higher Alzheimer disease risk may be shaped in part by midlife neuroendocrine aging, especially the menopause transition, rather than by longevity alone. It highlights early menopause, bilateral oophorectomy, vasomotor symptoms, and midlife cognitive changes as underinvestigated but potentially important risk markers, while calling for sex-specific, biomarker-driven prevention strategies.

New pathway explains poor response to bladder cancer immunotherapy

Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center have discovered a biological pathway that helps explain why some bladder cancers do not respond well to immunotherapy.

Stopping GLP-1 treatment linked to increase in risk of major cardiovascular events

Following a rapid increase in popularity of GLP-1 drugs for diabetes and weight loss, such as semaglutide and tirzepatide, approximately one in eight U.S. adults now take these medications, which also provide cardiovascular benefits.

Thymus health in adults linked to longer life and disease risk

Two new studies from investigators at Mass General Brigham challenge a decades-old assumption that the thymus, an organ best known for its role in establishing immune function in childhood, becomes irrelevant in adulthood.

Early menopause linked to higher lifetime heart disease risk

Women who enter natural menopause before age 40 face about a 40% higher lifetime risk of developing coronary heart disease than women who experience menopause later, according to a large Northwestern Medicine study that is the first to calculate lifetime heart risk associated with premature menopause.

Study finds a clear link between ultraprocessed food and heart disease risk

A prospective analysis of 6,531 adults in the multiethnic MESA cohort found that higher ultraprocessed food intake was associated with a graded increase in incident ASCVD risk, with each additional daily serving linked to about a 5% higher risk. The association was stronger in Black participants, while no significant interaction was seen by sex or income.

Gut-derived blood markers may help predict who develops coronary heart disease

Researchers used five prospective cohorts from the US and China to identify circulating gut microbiota-related metabolites linked to future coronary heart disease, then tested the findings through discovery, in silico validation, and targeted quantitative validation. The study ultimately highlighted nine metabolites associated with incident CHD, supporting a potential role for microbial metabolism in heart disease risk while not proving causation
