Digital screen time and nearsightedness

A systematic review and dose-response meta-analysis found a daily 1-hour increment in digital screen time was associated with a 21% higher odds of myopia. Researchers suggest that exposure to screens for less than 1 hour per day may be safe, but prolonged use increases the risk of nearsightedness.

Once-weekly semaglutide in adults with alcohol use disorder

Researchers found that low-dose semaglutide can reduce craving and some drinking outcomes in adults with alcohol use disorder, providing initial prospective evidence for its potential as a treatment. Larger clinical trials are needed to fully evaluate the efficacy of glucagon-like peptide 1 receptor agonists (GLP-1RAs) for this condition.
