 | | |  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. | | | | |  Study finds GLP-1 medicines cut fat while preserving muscle function Researchers found that GLP-1 medicines caused weight loss mainly through fat reduction, with only modest decreases in absolute muscle mass and no disproportionate loss of muscle function. In mice, physical performance improved, while in a small 12-week human pilot trial, strength was preserved despite reduced thigh muscle size. | |

|  | | | | |  Yogurt, cheese, and chocolate consumption is tied to reduced mortality risk, researchers report A large meta-analysis of 50 cohort studies involving over three million adults found that higher consumption of certain fermented foods is associated with lower risks of all-cause and cardiovascular mortality. Fermented milk products also showed inverse associations with cancer mortality, while other foods like miso and bread showed no consistent effects. | |  | | | | |  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. | | | | | | |  How one antibiotic dose can reshape your gut microbiome for years Long-term registry-linked analysis of nearly 15,000 adults shows that antibiotic use is associated with persistent changes in gut microbiome diversity and composition for up to 4–8 years. These effects vary by antibiotic class, with clindamycin, fluoroquinolones, and flucloxacillin showing the strongest and most sustained associations. | |

| | | |  A cross-sectional NHANES study of 2,582 U.S. women found that higher ultra-processed food intake was associated with lower odds of being classified as fertile based on self-reported infertility history. Greater Mediterranean diet adherence was linked to higher odds of fertility in adjusted models, but that association was no longer significant after accounting for obesity. | | | | |  In older Swedish adults, higher meat intake was associated with slower cognitive decline and lower dementia risk among people carrying APOE ε3/ε4 or ε4/ε4, but not among other genotype groups. A higher processed-to-total meat ratio was linked to worse dementia outcomes, while unprocessed red meat and poultry showed no substantial difference. | | | | |  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. | | | | |  In a large target trial emulation of 174,678 people with type 1 diabetes, GLP-1 receptor agonist initiation was associated with lower risks of major cardiovascular events and end-stage kidney disease over five years. The study also found no increased risk of hospitalization for diabetic ketoacidosis or severe hypoglycemia, supporting further randomized trials of GLP-1RAs as adjunctive therapy in type 1 diabetes. | | | | |  A study highlights a gap in cancer prevention, showing men undergo genetic testing less often yet are more likely to carry high-risk cancer variants. | | | | |  Researchers discovered an antioxidant, glutathione, that cancer cells appear to be "addicted to" as fuel, opening new pathways for investigation and a potential drug that can restrict the way tumors use this nutrient. | | | | |  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 | | | | |  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. | | | | |  For women age 70 and over with a common form of breast cancer, determining "the right size" of treatment can be challenging, in part because clinicians have limited tools to guide individualized treatment decisions. | | | | |  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. | | | | |  Patients with leptomeningeal metastasis (LM) have historically had few treatment options. Now, researchers from The University of Texas MD Anderson Cancer Center have found a combination of targeted therapies, tucatinib and trastuzumab, plus the chemotherapy drug, capecitabine, may improve symptoms and extend survival in some breast cancer patients with LM. | | | | | Women are more likely to survive cancer than men but face a higher risk of serious and adverse side effects from treatment, according to a landmark international study from Adelaide University. | | | | | Weight loss drugs have been linked to an increased risk of premature births among women who took them inadvertently just before or during early pregnancy to treat pre-existing diabetes. | |
