Q: Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.
Oxidative stress may be involved in occurrence of postoperative delirium (POD) and cognitive dysfunction (POCD). 8-iso-Prostaglandin F2 (8-iso-PGF2), an isoprostane derived from arachidonic acid via lipid peroxidation, is considered a gold standard for measuring oxidative stress. The present study aimed to investigate the ability of postoperative plasma 8-iso-PGF2 levels to predict POD and POCD in elderly patients undergoing hip fracture surgery.', 'Postoperative plasma 8-iso-PGF2 levels of 182 patients were measured by an enzyme-linked immunosorbent assay. We assessed the relationships between plasma 8-iso-PGF2 levels and the risk of POD and POCD using a multivariate analysis.', 'Plasma 8-iso-PGF2 levels and age were identified as the independent predictors for POD and POCD. Based on areas under receiver operating characteristic curve, the predictive values of 8-iso-PGF2 were obviously higher than those of age for POD and POCD. In a combined logistic-regression model, 8-iso-PGF2 significantly enhanced the areas under curve of age for prediction of POD and POCD.
