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.

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.

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.

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.

Beer, wine or spirits: A large study finds different mortality patterns for each

Researchers analyzed data from 340,924 UK Biobank participants and found that high total alcohol consumption was associated with greater all-cause, cardiovascular, and cancer mortality, while moderate consumption was linked to increased cancer mortality. Beer/cider and spirits showed associations with higher mortality across several outcomes, whereas low-to-moderate wine consumption was linked to lower mortality for certain outcomes, though the observational study cannot establish causation.

Non-dairy creamer drives up calorie count in coffee cups

While Americans have been drinking roughly the same amount of coffee over recent years, the calories in those cups have increased thanks primarily to the addition of non-dairy creamer, according to a new study from researchers at the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University.

Like father, like son? Study reveals a surprising pattern in male reproductive health

Researchers examining 117 father-son pairs from Denmark and Finland identified weak but statistically significant familial associations in several male reproductive traits, including testicular size, sperm concentration, selected hormone levels, and genital measurements. The findings suggest that reproductive characteristics show limited resemblance across generations, although the study could not determine the relative contributions of genetic and environmental factors.
