Could GLP-1 drugs help women with PCOS beyond weight loss?

A scoping review of 28 studies suggests that GLP-1 receptor agonists may improve androgen levels and menstrual function in women with polycystic ovary syndrome (PCOS), alongside their established metabolic benefits. Evidence for improved ovulation, fertility, and pregnancy outcomes remains limited, and the researchers could not determine whether reproductive benefits result directly from the drugs or from weight loss and improved metabolic health.

Eating walnuts was linked to higher IgG levels, but what does that mean for health?

A two-year randomized trial involving 474 older adults found that daily consumption of 30–60 grams of walnuts was associated with 6% higher total serum IgG concentrations compared with a control diet, with an 11% difference observed among US participants. Walnut consumption did not significantly affect IgM, MDA-LDL or MDA-LDL-specific antibodies, and whether the modest IgG difference has meaningful cardiovascular benefits remains unknown.

Extreme heat and cold hit some people far harder, and it's not just about illness

Researchers analysing 285,444 adults in Finland and the UK found that excess mortality associated with extreme heat and cold was more than tenfold higher among people with both pre-existing medical conditions and socioeconomic disadvantage than among those with neither or only one vulnerability. Climate modelling suggested that warming from approximately 1°C to 4°C could increase the proportion of deaths attributable to extreme temperatures from around 1% to more than 5% in both countries.

Norrin treatment prevents vision loss in diabetic rats

Over 100 million people in the U.S. are affected by diabetic retinopathy, a complication of diabetes that affects the eyes.

More than one-quarter of Americans exaggerate symptoms to obtain antibiotics

More than a quarter of Americans have exaggerated or made up symptoms to try to get antibiotics from their doctor, either for themselves or for their children, a new study has found.

Discarded fruit and vegetable parts offer overlooked fiber benefits

Most of us routinely discard the peels, skins, stalks, and seeds of fruits and vegetables at mealtime. But new research from King's College London suggests these scraps could be a valuable – and overlooked – source of dietary fiber, offering potential benefits for both public health and the environment.

Major studies identify accurate non-invasive tests for liver disease

Two major international studies have delivered the strongest evidence to date on which non-invasive tests can accurately diagnose and measure the severity of metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form, MASH, reducing reliance on liver biopsy.

New metabolic score may help predict healthy aging and disease risk

Studies conducted in various countries indicate that approximately 60% of people over the age of 65 currently live with two or more chronic conditions simultaneously.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

Study redefines picobirnavirus as a bacteria hunting virus

Thriving alongside trillions of bacteria in the human digestive tract is a vast population of viruses. Ever since one such denizen of the gut microbiome, known as picobirnavirus, was first spotted decades ago, researchers thought it directly infected human tissue and played a role in gastrointestinal illness.

New Yale initiative explores the role of inflammation in disease

Yale School of Medicine (YSM) was awarded a $10 million grant from the Blavatnik Family Foundation (BFF) to launch a new research initiative in the field of inflammation science.

Unraveling the mystery behind lower cancer risks in type 1 diabetes patients

New research in The Journal of Immunology uncovers how high blood sugar (hyperglycemia) and type 1 diabetes (T1D) may protect against certain cancers like melanoma, breast and colon cancer. T1D has been associated with a decreased risk of certain cancers, but the exact reasons why have remained a mystery. New data from studies in mice, now shows that it could be due to changes in immune cells, called T cells, caused by hyperglycemia.

Thyroid cancer risks and medication timing with oral GLP-1s

Like most prescriptions, glucagon-like peptide 1 (GLP-1) medications to manage weight come with potential risks.

Limited app use adds a twist to a nurse-led dementia risk trial

A cluster-randomized trial involving 403 Australian adults aged 45–65 found that a 12-month nurse-led behavioral intervention supported by a mobile app modestly improved estimated dementia risk scores compared with brief counseling and usual care. The study found no significant improvements in cognitive performance or other secondary outcomes, leaving its long-term effects on dementia prevention uncertain.

High-fat diets in mouse parents alter offspring brain development

Researchers fed breeding pairs of mice five diets with different fat and sugar contents to examine how parental nutrition affects offspring brain development. High-fat diets, alone or combined with high sugar, delayed early motor development and altered brain structure in young adult offspring, while the high-sugar-only diet produced no significant changes in individual brain regions after correction for multiple comparisons.
