A long-term analysis of major prediabetes trials found that achieving remission or returning glucose levels to normal was associated with over a 50% reduction in cardiovascular death or heart failure, with durable benefits decades later; delaying diabetes without remission did not show similar benefit. A randomized trial in critically ill adults found no difference in 28-day mortality between ketamine and etomidate for intubation, though ketamine increased the risk of cardiovascular collapse. Finally, molecular data showed indoor tanning causes widespread DNA mutations linked to melanoma, reinforcing its carcinogenic risk.
