Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.

Retatrutide reshapes metabolism in obesity and type 2 diabetes, study finds

Retatrutide altered circulating metabolites and lipids linked to fatty acid oxidation and insulin resistance in people with obesity, with or without type 2 diabetes. These biomarker changes suggest improved metabolic health, but the post-hoc analysis remains hypothesis-generating and does not prove direct clinical benefit.

New analysis shows obesity rates plateauing in many countries

An international large-scale study involving the University of Granada (UGR) examines obesity trends since the 1980s and reveals that the increase has slowed, stabilized, and even reversed in many countries, though it is still rising in developing nations.

Chronic liver disease threatens millions across Europe, report finds

Europe is facing a growing chronic liver disease threat, according to a new Series published today in The Lancet Regional Health – Europe, that engaged more than 75 co-authors from 30 countries and was led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by the "la Caixa" Foundation.

Indian adapted Mediterranean diet targets inflammation in heart disease trial

The paper describes a single-center randomized controlled trial testing whether an Indian Adapted Mediterranean Diet can reduce dietary inflammation in adults with stable coronary artery disease or moderate-to-high cardiovascular risk. The protocol will assess changes in the Dietary Inflammatory Index, inflammatory biomarkers, cardiometabolic risk factors, body measurements, and metabolic hormones over six months.

Researchers link surgical weight loss to reduced female cancer mortality rates

Substantial and sustained weight-loss has been linked to a reduced risk of cancer and cancer-related death, mainly in women. Two new studies now provide clues to why the risk is reduced - and suggest that gender, metabolism and genetics may play a crucial role.

Food insecurity links to poorer mental and physical health in Tasmania

Food insecurity among adults in Tasmania was strongly associated with lower diet satisfaction and poorer self-rated mental and physical health, with diet dissatisfaction showing the strongest link. The findings suggest that food insecurity limits not only nutrition, but also food choice, agency, wellbeing, and equitable access to acceptable, affordable, and culturally appropriate diets.

Blood carotenoids offer the clearest signal of fruit and vegetable eating habits

The review finds that several candidate biomarkers may help estimate fruit and vegetable intake more objectively than self-reported dietary tools, but most remain limited by specificity, sampling burden, supplement use, or incomplete validation. Blood and skin carotenoids appear strongest for habitual intake, while vitamin C, folate, urinary flavonoids, hippuric acid, and potassium may be more useful for short-term intake or intervention adherence.

New clinical guidelines outline strategies to improve postpartum cardiovascular care

A new Expert Consensus Decision Pathway by the American College of Cardiology (ACC) provides recommended strategies for improving postpartum care for individuals with and at risk for short- and long-term cardiovascular disease (CVD).

Semaglutide helps patients who gain weight after bariatric surgery

New UCL research supports use of the weight loss drug semaglutide for patients who do not get enough benefit from bariatric surgery.

NIH researchers discover how weight-loss drugs alter brain cells

A team of researchers at the National Institutes of Health (NIH) have unveiled new details about the events GLP-1 receptor agonists trigger within neurons, which have been largely unexplored until now.

Research show worsening health trends for post-1946 generations

Younger generations appear to be experiencing poorer health earlier in life than previous generations, according to a review of studies comparing national birth cohort datasets involving tens of thousands of people across the UK born since 1946.

Weight loss helps older AF patients slim down, but does not ease symptoms

An 8-month low-calorie diet plus behavioral support helped older adults with overweight or obesity and persistent atrial fibrillation lose weight safely, with no intervention-related serious adverse events. However, the LOSE-AF trial found no meaningful improvement in AF symptoms, rhythm control, AF burden, cardiac remodeling, or further AF procedure rates compared with usual care.

Study supports routine childhood screening for type 1 diabetes

For ten years, the Fr1da study, coordinated by Helmholtz Munich, has been investigating whether early stages of type 1 diabetes in children can be detected in routine pediatric care.

HonorHealth Research Institute tests steam therapy for diabetes treatment

HonorHealth Research Institute is looking to become the first research facility in the nation to begin a new clinical trial that aims to modify the lining of the digestive tract with the use of steam energy to control type II diabetes without the use of drugs.

Elevated blood glucose during pregnancy signals a significantly higher future diabetic risk

Gestational diabetes is a strong risk factor for future type 2 diabetes, even in women with normal pre-pregnancy weight, according to a study at the University of Gothenburg. The researchers call for earlier testing and better follow-up.

GLP-1 drugs may help curb addiction by targeting reward pathways

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

Minimal exposure to modern medicine rapidly alters the human microbiome

Even minimal exposure to modern medicine can rapidly change the human microbiome. In a new study publishing May 20 in the Cell Press journal Cell Reports, researchers reveal that the gut microbes of remote Amazonian Indigenous communities began shifting toward patterns more commonly seen in urban, industrialized populations after only a few medical visits.
