Studies compare Shingrix to Zostavax and find reductions in heart disease, stroke, and dementia, with stronger signals in men for heart outcomes.
A seven-year study of about 41,000 adults in South Korea finds that modest weekend catch-up sleep—about 1 hour 27 minutes—reduces the risk of high blood pressure by up to 9%, with larger benefits for physically inactive individuals. Excessive weekend sleep (>4 hours) may offset gains. Findings were presented at the European Society of Cardiology congress in Munich.
New lawsuits claim GLP-1 diabetes drugs may cause nonarteritic anterior ischemic optic neuropathy (NAION), a rare but serious eye condition.
