Renal resistive index assessment by intraoperative transesophageal echocardiography is associated with acute kidney injury after cardiac surgery: a prospective observational study.
Acute kidney injury (AKI) is a major health burden after cardiac surgery. Renal vasoconstriction and venous congestion can be assessed via transesophageal echocardiography (TEE). The primary objective is to determine feasibility of measuring intraoperative Renal resistive index (RRI) and portal vein pulsatility fraction (PF) by TEE. The secondary objectives are to determine the association between RRI and/or PF and postoperative AKI, Intensive Care Unit (ICU) length of stay, hospital length of stay, and 30-day mortality. ⋯ This study demonstrates high feasibility for obtaining intraoperative TEE measurement of RRI and PF and significant correlation between postoperative AKI with pre CPB RRI, post chest closure RRI, and the combination of RRI at the three timepoints.

Preoperative Biofluid Biomarkers for Predicting Postoperative Neurocognitive Disorders in Older Adults: A Systematic Review.
Preoperative biofluid biomarkers reflecting pathophysiological, neuronal injury, and inflammation as well as those for Alzheimer's disease (AD) may be valuable tools for the risk stratification of perioperative neurocognitive disorders (PNDs) in older adults. We summarized current evidence relating these preoperative biomarkers to PND beyond 7 days, in older surgical participants aged ≥60 years. Studies that evaluated the association of preoperative biomarkers with cognitive decline as an outcome, beyond 7 days, were identified through searches of 6 databases and 3 trial registries to 17 January 2024. ⋯ In conclusion, preoperative biofluid amyloid biomarkers may hold potential utility for the prediction of POCD, although current evidence remains limited. Other potential preoperative biomarkers for POCD included p-Tau181 and Neurofilament Light, however small sample sizes, study heterogeneity, and conflicting results limited conclusions drawn. Standardized cognitive outcome metrics and common assessment timeframes are additionally required in future studies to ascertain the prognostic utility of these biomarkers for POCD.

Comparison of remimazolam and propofol on postoperative subjective quality of recovery in patients undergoing general anesthesia: a meta-analysis of randomized controlled trials.
Remimazolam, a recently approved drug for surgical sedation and general anesthesia, has been compared with propofol in previous studies regarding its efficacy as a general anesthetic. However, the question of whether remimazolam demonstrates non-inferiority to propofol in postoperative subjective quality of recovery (QoR) among patients under general anesthesia has not been definitively answered. ⋯ Remimazolam is similar to propofol in terms of postoperative subjective QoR for patients receiving general anesthesia.
