Background: Patients requiring posterior lumbar surgery have increased annually. Incision infection after lumbar surgery has serious consequences for patients. However, data on the related factors of incision infection after lumbar surgery in diabetic patients are limited. Therefore, this study aimed to analyze diabetic patients who underwent lumbar surgery and to explore the risk factors of perioperative incision infection to provide a scientific basis for perioperative intervention of lumbar spine surgery and reduce risk of incision infection in such patients. Methods: We retrospectively reviewed data of diabetic patients who underwent posterior lumbar surgery from 2011 to 2016. A total of 523 diabetic patients undergoing posterior lumbar surgery were analyzed for the influence of various risk factors on postoperative incision infection. Univariate and multivariate logistic regression was performed. The test level was α=.05, and P < .05 was considered statistically significant. Results: In the past 6 years, among the 523 diabetic patients, the incidence of incision infection after posterior lumbar surgery was approximately 7.1%, of which the shallow incision infection rate was 4.2% and the deep incision infection rate was 2.9%. Incision infection of posterior lumbar surgery in diabetic patients is related to smoking, preoperative glycosylated hemoglobin A1c, postoperative albumin (Alb), surgical segment, operation time, and intraoperative blood loss, especially on postoperative fasting blood glucose, postoperative postprandial blood glucose, local subcutaneous fat thickness, and operation sequence (odds ratio >5.00). Meanwhile, sex, age, body mass index (BMI), preoperative Alb, and newly diagnosed diabetes were not highly correlated with incision infection after posterior lumbar surgery. Conclusion: Local subcutaneous fat thickness is a better indicator for predicting incision infection compared with BMI. In diabetic patients undergoing lumbar surgery, actively controlling blood glucose fluctuations, restoring normal diet early after surgery, and optimizing surgical procedures to reduce trauma and operative time can effectively reduce the risk of infection after posterior lumbar surgery.

ObjectiveThe study aimed to examine the effects of hearing aids on cognitive function in middle-aged and older adults with hearing loss.Data sources and study selectionPubMed, Cochrane Library, and Embase were searched for studies published before 30 March 2022. Randomized controlled trials (RCTs) and non-randomized studies of interventions (NRSIs) were included in the search. Restriction was set on neither types, severity, or the time of onset of hearing impairment nor cognitive or psychiatric statuses.Data extraction and synthesisTwo independent reviewers extracted data and assessed the study quality of RCTs. Cognitive function outcomes were descriptively summarized and converted to standardized mean difference (SMD) in the meta-analysis. Meta-analysis was conducted in RCTs. Sub-group analyses were conducted by cognitive statuses, psychiatric disorders, and cognitive domains.ResultsA total of 15 studies met the inclusion criteria, including five RCTs (n = 339) and 10 NRSIs (n = 507). Groups were classified as subjects without dementia or with normal global cognition, subjects with AD or dementia, and subjects with depressive symptoms. For subjects without dementia, improvements were found in global cognition, executive function, and episodic memory. For subjects with depressive symptoms, improvements were found in immediate memory, global cognition, and executive function. No improvement was found in subjects with AD or dementia. In total, four RCTs were included in the meta-analysis. For subjects without dementia (SMD = 0.11, 95% confidence interval [CI]: −0.15–0.37) and those with AD, no significant effect was found (SMD = −0.19, 95% CI: −0.65–0.28). For subjects without dementia, no significant effect was found in language (SMD = 0.14, 95% CI: −0.30–0.59) or general executive function (SMD = −0.04, 95% CI: −0.46–0.38). Further sub-group analysis found no significant effect in executive function (SMD = −0.27, 95% CI: −0.72–0.18) or processing speed (SMD = −0.02, 95% CI: −0.49–0.44).ConclusionHearing aids might improve cognitive performance in domains such as executive function in subjects without dementia. The effects on subjects with depressive symptoms remained unclear. No improvement was found in subjects with AD or dementia. Long-term RCTs and well-matched comparison-group studies with large sample sizes are warranted.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022349057.

Background Cognitive impairment is one of the primary sequelae affecting the quality of life of patients with Japanese encephalitis (JE). The clinical treatment is mainly focused on life support, lacking of targeted treatment strategy. Methods A cerebrospinal fluid (CSF) proteomic profiling study was performed including 26 patients with JE in Gansu province of China from June 2017 to October 2018 and 33 other concurrent hospitalized patients who were excluded central nervous system (CNS) organic or CNS infection diseases. The clinical and proteomics data of patients with JE were undergoing combined analysis for the first time. Results Two subtypes of JE associated with significantly different prognoses were identified. Compared to JE1, the JE2 subtype is associated with lower overall survival rate and a higher risk of cognitive impairment. The percentages of neutrophils (N%), lymphocyte (L%), and monocytes (M%) decreased in JE2 significantly. Conclusions The differences in proteomic landscape between JE subgroups have specificity for the prognosis of cognitive impairment. The data also provided some potential target proteins for treatment of cognitive impairments caused by JE. Trial registration ChiCTR, ChiCTR2000030499.
