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.

New research center aims to accelerate hepatitis C vaccine development

The shifty hepatitis C virus (HCV) has a knack for outmaneuvering the immune system. Its secret is an especially high mutation rate, which has generated an abundance of viral variants with extreme genetic diversity.

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.

CT scans linked vitamin D levels to fat within muscles after bariatric surgery

Researchers followed 113 adults for one year after bariatric surgery and found that those with higher postoperative vitamin D concentrations had less fat infiltration within certain muscles and lower visceral adiposity. They found no significant association between increases in vitamin D and changes in body composition after correction for multiple comparisons, while preoperative vitamin D levels did not independently predict postoperative body composition.

Men with lower testosterone at 31 reported good health 15 years later

Researchers analyzed testosterone concentrations measured at age 31 in 2,691 Finnish men and assessed self-reported health, medical conditions, and quality of life at age 46. Men across testosterone quartiles generally reported good health and excellent quality of life, while differences in metabolic and gastrointestinal conditions lost statistical significance after adjustment for waist circumference.

High-scoring endocrinologists are more likely to prescribe key diabetes drugs

Endocrinologists who scored highest on the American Board of Internal Medicine's Longitudinal Knowledge Assessment (LKA®) were more likely to prescribe a key diabetes drug class following a treatment guidelines update compared to doctors with lower scores.

Endometrial cancer rates rise sharply among younger South Texas women

An Upper-South region of Texas including San Antonio and Bexar County had the state's highest hysterectomy-corrected incidence of endometrial cancer and the largest increase over time, a study led by scientists at The University of Texas at San Antonio Health Science Center and the National Cancer Institute showed.

High intake of saturated fat can promote favorable changes in cardiovascular risk markers

New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor.

Millions get GLP-1 drugs through channels insurance records may miss

Researchers analyzed reports from 9,150 US adults and found that current or previous GLP-1/GIP use rose from 8.2% to 12% between March 2024 and October 2025, largely driven by weight-loss indications. They also estimated that approximately one-third of users obtained treatment through nontraditional channels that standard insurance claims may fail to capture.

Beer and liquor show more oral bacteria links than wine in a large US study

Researchers analyzed beverage intake and oral microbiome data from 5,598 adults across three US cohorts and found that alcohol consumption showed the strongest associations with oral bacterial diversity and composition among the beverages examined. Higher alcohol intake was associated with greater bacterial richness and differences in genera linked to oral health, but the cross-sectional preprint could not establish whether alcohol caused these differences or influenced disease risk.

The vaginal microbiome may relate to more than reproductive health

Researchers analyzed vaginal microbiota, metabolites, and psychological questionnaire scores in 105 young Italian women and found associations between microbial community types and reward responsiveness, motivational drive, and behavioral inhibition. Exploratory models identified statistical links involving vaginal GABA and valine, but the cross-sectional study could not establish whether microbiome changes influence psychological functioning or the reverse.

New report urges unified lifecycle approach to women's heart health

A new approach to women's heart health may offer them a lifetime of opportunities. A trio of scientific papers, published today in the journal Circulation, spells out how fluctuating hormones, mental health and well-being, the heart and the brain are linked and how those connections need to be a routine part of care from a young age.
