Higher periconception parental vitamin B12 levels and higher postconception maternal red blood cell (RBC) folate levels were associated with lower predicted prevalences of birth defects in a prospective cohort study from Shanghai, China. The study included 3032 couples with biomarker measurements obtained within 4 months before conception and 17,765 women […]
The US updated evidence-based recommendations provide clinicians with comprehensive guidance on when to initiate pharmacologic migraine prevention, how to select an appropriate preventive medication, and how to monitor treatment effectiveness, adverse effects, and medication discontinuation in adults. Developed by a multidisciplinary panel using a systematic review of studies published through […]
In a US retrospective observational cohort study of 623 young adults, significant infradian (multiday) heart rate rhythms were detected in 70% of participants, with 36% showing two or more distinct rhythms. Using up to four years of wearable and questionnaire data from the University of Notre Dame’s NetHealth project, researchers […]
Early-life sugar restriction during pregnancy and infancy was associated with a 34% lower risk of early-onset cancer (diagnosed by age 50), although it was not associated with a significant reduction in cancer-specific mortality. Using a natural experiment created by the end of UK sugar rationing, researchers analyzed 63,819 UK Biobank […]
In US adults aged ≥65 years, overweight and class I–II obesity were associated with lower all-cause mortality risk, whereas high waist circumference and being underweight were associated with higher mortality risk, highlighting the importance of central adiposity and the limitations of BMI alone for mortality risk stratification. Using 14 years […]
In the German multicenter study of 5,521 patients with colorectal cancer (CRC), the apparent survival advantage associated with overweight and obesity at diagnosis was largely explained by cancer-associated weight loss before diagnosis. Compared with patients with normal weight, those who were overweight had modestly better overall survival (HR, 0.89), whereas […]
In a US longitudinal multi-omic study of 1,154 hospitalized patients with COVID-19 from the IMPACC cohort, significant reactivation of Herpesviridae and Anelloviridae was common during acute COVID-19, with virus-specific temporal patterns and associations with disease severity, host immune responses, and clinical outcomes. Chronic viral infections are ubiquitous in humans, and […]
Accelerated biological aging was associated with a higher risk of early-onset solid cancers in young adults, particularly lung, gastrointestinal, and uterine cancers, suggesting that biological aging may help explain the rising incidence of cancer in recent generations. In a study of 154,169 young adults from the UK Biobank, systemic biological […]
A systematic review and network meta-analysis of 262 randomized trials involving 99,791 participants found that anti-obesity medications vary substantially in both effectiveness and safety, with greater weight loss generally accompanied by higher rates of adverse events and treatment discontinuation. At one year, tirzepatide and cagrilintide-semaglutide (CagriSema) produced the greatest confirmed […]
Baseline use of proton pump inhibitors (PPIs) and, to a lesser extent, antibiotics was associated with poorer outcomes in patients with unresectable stage III non-small cell lung cancer (NSCLC) treated with durvalumab after chemoradiotherapy, suggesting these medications may reduce the benefit of immunotherapy. This post-hoc analysis of the phase 3 […]
