A 2022 national study shows frailty, not chronological age, is a stronger predictor of 30-day postoperative mortality across surgical risk levels, challenging age-based surgical decision-making.
This cohort study demonstrates that postoperative sleep architecture is differentially disrupted based on surgical risk. High-risk procedures cause prolonged deficits in REM and deep sleep, which are associated with increased complications,
Elevated plasma TMAO levels are associated with higher risk of abdominal aortic aneurysm development, rapid aneurysm growth, and need for surgical repair, providing a promising tool for risk stratification and personalized surveillance.
