We explored promising predictors for POCD in elderly patients after hip fracture surgery.<\/jats:p>\n               <jats:p>Methods: Elderly subjects (aged \u226565 years) undergoing surgery for hip fracture were consecutively recruited. Neuropsychological assessments were performed 1 day preoperatively (baseline) and 7 days postoperatively, and POCD was defined using the \u2018Z scores\u2019 method. Clinical data and laboratory tests were compared between patients with and without POCD development. Binary univariate and multivariate logistic regression analyses were conducted for risk factor assessment. Receiver operating characteristic (ROC) curve analysis was performed to investigate the predictive value of malondialdehyde (MDA) on postoperative day 1 (POD1) for POCD.<\/jats:p>\n               <jats:p>Results: A total of 198 patients were finally enrolled in the analysis and 51 patients exhibited POCD within 7 postoperative days, with an incidence rate of 25.8%. MDA expression on POD1 (OR: 1.12, 95%CI: 1.03\u20131.23, P=0.017) was the only independent risk factor for POCD according to the final multivariate logistic regression analysis. ROC curve analysis indicated that MDA on POD1 was a predictor for POCD, with an area under the curve (AUC) of 0.683 and 95%CI of 0.590\u20130.775 (P&amp;lt;0.001).<\/jats:p>\n               <jats:p>Conclusions: In conclusion, we demonstrated that MDA on POD1 was an independent risk factor for POCD in elderly subjects undergoing hip fracture surgery.<\/jats:p>","DOI":"10.1042\/bsr20190166","type":"journal-article","created":{"date-parts":[[2019,5,28]],"date-time":"2019-05-28T19:46:10Z","timestamp":1559072770000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Malondialdehyde on postoperative day 1 predicts postoperative cognitive dysfunction in elderly patients after hip fracture surgery"],"prefix":"10.1042","volume":"39","author":[{"given":"Chunxian","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, The Affiliated Hospital of Medical School, Ningbo University, No. 247 Renmin road, Ningbo City 315000, Zhejiang Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Affiliated Hospital of Medical School, Ningbo University, No. 247 Renmin road, Ningbo City 315000, Zhejiang Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1665-6939","authenticated-orcid":false,"given":"Yu","family":"Gui","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Affiliated Hospital of Medical School, Ningbo University, No. 247 Renmin road, Ningbo City 315000, Zhejiang Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2019,6,20]]},"reference":[{"key":"2021111619394981900_B1","doi-asserted-by":"publisher","first-page":"705","DOI":"10.1038\/nrn.2016.128","article-title":"Lasting impact of general anaesthesia on the brain: mechanisms and relevance","volume":"17","author":"Vutskits","year":"2016","journal-title":"Nat.
