In two UK cohorts including 977,282 adults, drinking beverages at a “very hot” temperature was associated with more than a threefold higher risk of esophageal squamous cell carcinoma (SCC), while drinking 6 or more hot beverages per day was associated with a 71% higher SCC risk. Over 11–14 years of […]
In a UK prospective cohort of 502,188 adults followed for a median of 13.6 years, mortality was lowest at hemoglobin concentrations approximately 1–3 g/dL above the current WHO anemia thresholds, while both lower and higher concentrations were associated with increased mortality. The association between hemoglobin and all-cause mortality was U-shaped: […]
Regular smoking was associated with a lower risk of Parkinson disease (PD), and among people who never smoked, higher levels of exhaled carbon monoxide (CO) were associated with a lower risk of PD in a broadly dose-dependent manner. This nationwide prospective cohort study included 512,724 adults aged 30–79 years from […]
Alcohol-attributable cancer deaths in the USA doubled from 11,361 in 1990 to 23,126 in 2023, with a disproportionate burden among men and adults aged 55 years and older. This population-based observational trend analysis used Global Burden of Disease data to examine age-standardized mortality rates (ASMRs) attributable to heavy alcohol use […]
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 […]
