Even moderate alcohol consumption was consistently linked to a higher risk of multiple cancers, with clear dose–response relationships showing that risk rises with greater frequency and quantity of drinking. In this systematic review of 62 U.S.-based studies, alcohol use was most strongly associated with increased risks of breast, colorectal, and […]
Adjunct low-dose, short-course corticosteroids probably reduce short-term mortality in adults with severe pneumonia or acute respiratory distress syndrome (ARDS), according to a review of 20 randomized trials involving 3459 participants. Drawing from major medical databases through September 2025, the analysis found that corticosteroids (3 mg/kg of body weight per day […]
Better mental wellbeing substantially reduces the risk of developing irritable bowel syndrome (IBS), with effects that are independent of genetic predisposition and partly mediated through lower depression and anxiety. In this prospective UK Biobank cohort of 75,842 IBS-free participants followed for 12.4 years, 1,400 incident IBS cases occurred, and higher […]
Higher physical activity in midlife and late life—but not early adulthood—is associated with a significantly lower risk of both all-cause and Alzheimer disease dementia. In this prospective analysis from the US Framingham Heart Study Offspring cohort, 1526 early-adult, 1943 midlife, and 885 late-life participants were followed for up to 37 […]
Clonal hematopoiesis of indeterminate potential (CHIP), particularly non-DNMT3A CHIP subtypes, is an independent risk factor for incident heart failure (HF) and may represent a novel therapeutic target. In a UK Biobank cohort of 417,616 adults (mean age, 56.1 years; 56.2% women) without prior HF or major comorbidities, 7,183 participants (1.7%) […]
Daily supplementation with n−3 polyunsaturated fatty acids (fish oil) significantly reduced the risk of serious cardiovascular events in patients receiving maintenance hemodialysis. In a double-blind, randomized, placebo-controlled trial across 26 sites in Canada and Australia, 1,228 adults on hemodialysis were assigned to receive either 4 g of fish oil daily […]
A systematic review and meta‐analysis suggests that influenza, SARS‐CoV‐2, HIV, hepatitis C virus, and herpes zoster are all associated with an increased risk of major cardiovascular events. The analysis included 155 studies, viral infections were consistently linked to higher rates of coronary heart disease (CHD) and stroke. HIV infection was […]
Ongoing peer-reviewed evidence supports the safety and effectiveness of vaccines against Covid-19, respiratory syncytial virus (RSV), and influenza during the 2025–2026 season. In a systematic review of 511 studies out of 17,263 identified references, Covid-19 mRNA vaccines targeting the XBB.1.5 subvariant showed pooled effectiveness against hospitalization of 46% from cohort […]
Findings of a UK clinical trial support the use of the Mediterranean diet (MD) as a first-line therapy for irritable bowel syndrome (IBS). A total of 139 adults with IBS (mean age 40.4 years; 80% women) from across the UK were randomized to follow either the MD (n = 68) […]
A systematic review and network meta-analysis evaluated the efficacy and safety of different exercise modalities for managing knee osteoarthritis, including aerobic, flexibility, mind-body, neuromotor, strengthening, and mixed exercises. A total of 217 randomized controlled trials involving 15,684 participants were analyzed, with outcomes assessed at short-term (4 weeks), mid-term (12 weeks), […]
