Preoperative homocysteine modifies the association between postoperative C-reactive protein and postoperative delirium.

Background: Homocysteine and C-reactive protein (CRP) may serve as biomarkers of postoperative delirium. We set out to compare the role of blood concentration of homocysteine versus CRP in predicting postoperative delirium in patients.

Materials And Methods: In this prospective observational cohort study, the plasma concentration of preoperative homocysteine and postoperative CRP was measured.

Preoperative Plasma Tau-PT217 and Tau-PT181 Are Associated With Postoperative Delirium.

Objective: This study aims to identify blood biomarkers of postoperative delirium.

Background: Phosphorylated tau at threonine 217 (Tau-PT217) and 181 (Tau-PT181) are new Alzheimer disease biomarkers. Postoperative delirium is associated with Alzheimer disease.
