Cerebral small-vessel disease and postoperative delirium in elderly non-cardiac surgical patients
Jun 5, 2026
The authors investigate the relationship between cerebral small-vessel disease and postoperative delirium in elderly non-cardiac surgical patients, hypothesizing that a higher burden of cerebral small-vessel disease is associated with an increased risk of delirium. Their findings reveal that pre-existing cerebral small-vessel disease significantly elevates the odds of postoperative delirium, with nearly half of the cases in the study potentially attributable to this condition. Specifically, lacunes and white matter hyperintensities were identified as key contributors to the increased risk.
Methodologic Insights on Building and Evaluating Models for Early Warning of Hypotension during Surgery
Jun 5, 2026
The authors investigate how data selection impacts the performance of models designed to predict hypotension during surgery. They find that excluding classification-altering interventions from training data significantly improves model accuracy, while the presence of ongoing hypotension in evaluation data can lead to misleading performance metrics. The study emphasizes the importance of careful data framing and selection to enhance the clinical utility of hypotension prediction models.
Higher versus Routine Intraoperative Blood Pressure Targets in Noncardiac Surgery: A Systematic Review and Meta-analysis with Trial Sequential Analysis of Randomized Trials
Jun 4, 2026
The authors aimed to determine whether targeting higher intraoperative blood pressure values during noncardiac surgery improves clinical outcomes compared to routine blood pressure management. Their systematic review and meta-analysis of 15 randomized trials involving over 15,000 patients found no significant benefits in major postoperative outcomes, such as acute kidney injury or mortality, although there was a potential reduction in postoperative delirium that requires further investigation. Overall, the findings suggest that higher blood pressure targets do not confer substantial advantages in this surgical context.
