A review of clinical trials, observational studies, genetic analyses, and mechanistic research suggests that atrial fibrillation risk may follow a U-shaped relationship with testosterone, increasing at both low and high levels. Evidence on testosterone replacement therapy remains mixed, with researchers calling for prospective studies to determine whether mid-physiological testosterone targets and treatment formulation influence AF risk.

Demographic reporting for medical AI remains inadequate, study shows

The recent flood of Artificial Intelligence (AI) models and content has undoubtedly brought along an unwelcome bug from the human-made content it scrapes from: bias. AI has been noted to form, copy, and amplify harmful stereotypes of already marginalized groups.

Coffee’s link to Parkinson’s risk may depend on how your body handles caffeine

In 435,551 UK Biobank participants followed for a median of 15.7 years, overall coffee consumption was not associated with Parkinson’s disease risk, but the relationship differed significantly according to CYP1A2 genotype. Lower risk was observed with low-to-moderate coffee intake among fast-metabolizer AA carriers, while higher intake was associated with increased risk among AC and CC carriers, although the observational findings do not establish causality and sex-specific patterns require cautious interpretation.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.

A narrative review found that maternal cannabis use may be associated with differences in breastmilk fat, protein, lactose, and the immune factor secretory immunoglobulin A, but evidence comes primarily from only two human studies and remains limited and inconsistent. The authors stress that maternal diet, food security, socioeconomic circumstances, and other forms of adversity could confound these associations and should be incorporated into future research.
