https://www.selleckchem.com/products/AZD8055.html Postoperative nausea and vomiting (PONV) is a common complication after total hip/knee arthroplasty (THA/TKA) that affects patient satisfaction and postoperative recovery. It has been reported that patients undergoing THA/TKA experience PONV at a frequency of 20-83%. This study investigates the occurrence of PONV in patients and analyzes the risk factors. Patients undergoing primary THA/TKA under general anesthesia from October 1, 2017, to May 1, 2018, were included. Data on patient-related factors were collected before THA/TKA. Anesthesia- and surgery-related factors were recorded postoperatively. Risk factors were analyzed using binary logistic regression. A stronger association of motion sickness and PONV was found at six hours after bilateral THA/TKA [nausea odds ratio (OR) =14.648, 3.939-54.470; vomiting OR =8.405, 2.482-28.466]. At 6-24 hours after bilateral THA/TKA, patients who had a history of migraines tended to experience nausea (OR =12.589, 1.978-80.105). Patients with lower body mass index (BMI) were more likely to experience PONV at 24-72 hours (nausea OR =0.767, 0.616-0.954; vomiting OR =0.666, 0.450-0.983) after bilateral THA/TKA. The incidence of PONV after primary bilateral THA/TKA was higher than that after unilateral THA/TKA. The risk factors vary at different time points after surgery, and a history of motion sickness is the most critical factor affecting PONV.

The aim of this study was to find genes with significantly aberrant expression in diabetic nephropathy (DN) and determine their underlying mechanisms. GSE30528 and GSE1009 were obtained by querying the Gene Expression Omnibus (GEO) database. The difference in target gene expression between normal renal t
