RESUMEN
ABSTRACT: COVID-19 survivors complained of the experience of cognitive impairments, which also called "brain fog" even recovered. The study aimed to describe long-term cognitive change and determine psychosocial factors in COVID-19 survivors. A cross-sectional study was recruited 285 participants from February 2020 to April 2020 in 17 hospitals in Sichuan Province. Cognitive function, variables indicative of the virus infection itself, and psychosocial variables were collected by telephone interview. Univariate logistic regression and Lasso logistic regression models were used for variable selection which plugged into a multiple logistics model. Overall prevalence of moderate or severe cognitive impairment was 6.3%. Logistic regression showed that sex, religion, smoking status, occupation, self-perceived severity of illness, sleep quality, perceived mental distress after COVID-19, perceived discrimination from relatives and friends, and suffered abuse were associated with cognitive impairment. The long-term consequences of cognitive function are related to multiple domains, in which psychosocial factors should be taken into consideration.

BACKGROUND: Emerging evidence shows that cognitive dysfunction may occur following coronavirus disease 19 (COVID-19) infection which is one of the most common symptoms reported in researches of "Long COVID". Several inflammatory markers are known to be elevated in COVID-19 survivors and the relationship between long-term inflammation changes and cognitive function remains unknown. METHODS: We assessed cognitive function and neuropsychiatric symptoms of 66 COVID-19 survivors and 79 healthy controls (HCs) matched with sex, age, and education level using a digital, gamified cognitive function evaluation tool and questionnaires at 15 months after discharge. Venous blood samples were collected to measure cytokine levels. We performed correlation analyses and multiple linear regression analysis to identify the factors potentially related to cognitive function. RESULTS: The COVID-19 survivors performed less well on the Trails (p = 0.047) than the HCs, but most of them did not report subjective neuropsychiatric symptoms. Intensive care unit experience (ß = -2.247, p < 0.0001) and self-perceived disease severity (ß = -1.522, p = 0.007) were positively correlated, whereas years of education (ß = 0.098, p = 0.013) was negatively associated with the performance on the Trails. Moreover, the abnormally elevated TNF-α levels (r = -0.19, p = 0.040) were negatively correlated with performance on the Trails in COVID-19 group. CONCLUSION: Our findings suggest that COVID-19 survivors show long-term cognitive impairment in executive function, even at 15 months after discharge. Serum TNF-α levels may be an underlying mechanism of long-term cognitive impairment in patients recovering from COVID-19.

BACKGROUND: The agenesis of corpus callosum (ACC) could impair the connectivity of the hemispheres of the cerebral cortex and cause cognitive impairments, social and behavioral issues, and even psychiatric disorders. Although social deficits are common in ACC patients, it is rare for a social anxiety disorder to occur. CASE PRESENTATION: To report a 17-year-old adolescent with complete ACC associated with social anxiety disorder, depression, impulsive behavior, and other neurodevelopmental defects such as intellectual disabilities. His avoidance and fear were improved after treatment with sertraline. CONCLUSIONS: This is the first report of social anxiety disorder in ACC patients. The possible relationship between brain structural abnormities and anxiety syndrome should be investigated in more studies.

OBJECTIVE: To investigate the clinical features and prognosis of autoimmune encephalitis (AE). METHODS: Accessing data from the electronic medical records of patients receiving care at West China Hospital, Sichuan University, China between 2013 and 2019, we conducted a retrospective study of the disease characteristics, laboratory examinations, treatment, and prognosis of AE patients. Before they were discharged, modified Rankin Scale (mRS) was used to assess the prognosis of AE patients and their mRS scores were then used to categorize patients as having good prognosis (mRS scores of 0-2) or poor prognosis (mRS scores of 3-6). Multivariate logistic regression was used to analyze risk factors associated with poor prognosis. RESULTS: A total of 121 patients were included in the study. The male-to-female ratio was 1â¶1.1. At the time of diagnosis, patients were mainly from the age group of young to middle-aged individuals. Among the 121 patients, 64.5% (78 patients) had anti-N-methyl D-aspartate receptor (NMDAR) encephalitis, accounting for the largest proportion. 33.1% (40 patients) first visited the Department of Psychiatry for medical assistance. 62.8% (76 patients ) showed prodromal symptoms. The common clinical manifestations of the AE patients at the time of admission included cognitive dysfunction (104 patients, 86.0%), thought disorder (90 patients, 74.4%), and altered behaviors (88 patients, 72.7%). The NMDAR antibody titers were higher in the cerebrospinal fluid (CSF) than those in the serum. Double-positive antibodies were detected in 6 patients. No abnormality was observed in the brain magnetic resonance imaging (MRI) of 42 patients (34.7%) . Electroencephalography abnormalities were observed in 71 patients (58.7%). 111 patients (91.7%) received first-line immunotherapy and 61 patients (50.4%) still had neuropsychiatric deficits when they were discharged. Multivariate logistic regression revealed that consciousness disorder (odds ratio [ OR] =4.230, 95% confidence interval [ CI] : 1.540-11.617; P=0.005), altered behavior ( OR=2.997, 95% CI: 1.068-8.406; P=0.037) and movement disorder ( OR=7.753, 95% CI: 1.446-41.578; P=0.017) were risk factors for poor clinical prognosis of AE patients. CONCLUSIONS: Patients with AE mainly manifest cognitive damage. Half of the patients left neuropsychiatric deficits. The relationship between CSF titers and serum titers is unparalleled. The options of immunotherapy show no difference in their influence on prognosis. Cognitive dysfunction, altered behavior and movement disorder are independent risk factors for a poor prognosis at discharge.

OBJECTIVE: To summarize the literature and systematically evaluate outcomes for ossification of posterior longitudinal ligament interventions including anterior cervical corpectomy and fusion (ACCF), anterior controllable antedisplacement and fusion (ACAF), laminoplasty (LP), and laminectomy with fusion (LF). METHODS: We searched PubMed, Embase, Web of Science, and the Cochrane Library from January 1990 to March 2021. Patient demographic data, Japanese Orthopaedic Association score, cervical lordosis and overall complications were analyzed. RESULTS: We evaluated 30 studies involving 2038 patients. Patients undergoing ACCF had improved Japanese Orthopaedic Association scores compared with patients undergoing LP (weighted mean difference [WMD] 1.17, 95% confidence interval [CI] 0.49-1.85) and LF (WMD 1.21, 95% CI 0.17-2.24). Patients with ACAF had better cervical lordosis compared with patients with ACCF (WMD 7.00, 95% CI 0.72-13.27), LP (WMD 10.27, 95% CI 4.64-15.90), and LF (WMD 8.98, 95% CI 2.48-15.47). Additionally, ACAF (odds ratio 0.24, 95% CI 0.07-0.84) and LP (odds ratio 0.50, 95% CI 0.28-0.90) had a lower incidence of complications compared with ACCF. CONCLUSIONS: Japanese Orthopaedic Association score outcomes indicated that ACCF was superior to LP and LF. ACAF had the largest cervical lordosis among all procedures. ACCF showed a higher incidence of overall complications compared with ACAF and LP.

OBJECTIVES: Early recognition and intervention of patients with the anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis are important to achieve a better prognosis. The study aims to summarize the real-world perspectives of anti-NMDAR encephalitis patients in China via electronic medical records (EMRs). METHODS: Using EMRs of patients from 2013 to 2019 from West China Hospital in China, a retrospective research was conducted to demonstrate the temporary rank of clinical characteristics and disease prognosis of anti-NMDAR encephalitis. The modified Rankin Scale (mRS) scores were used to divide the anti-NMDAR-encephalitis into two groups (poor prognosis vs. good prognosis). Chi-square test and logistic regression were used to analyze factors associated with prognosis. RESULTS: Here, 78 patients were included. The most common clinical characteristics are cognitive dysfunction (86.0%) and thought disorder (86.0%). Cognitive dysfunction, thought disorder, and seizures tended to appear soon after prodrome symptoms. Logistics analysis results showed that cognitive dysfunction (OR = 4.48, 95% CI = 1.09-18.47), the score of (GCS ≤ 8) (OR = 4.52, 95% CI = 1.18-17.32), positive antibodies in serum (OR = 4.89, 95% CI = 1.19-20.13) and delay immunotherapy (OR = 4.76, 95% CI = 1.79-12.60) were risk factors of poor clinical outcomes. CONCLUSIONS: There are two peaks in the development of autoimmune encephalitis (AE). The first peak is cognitive dysfunction, and the second peak is autonomic dysfunction. Cognitive dysfunction and GCS score ≤8 at admission, antibodies positive in serum, and delay immunotherapy were risk factors for a poor prognosis at discharge.
