Purpose: To compare the effectiveness of the Cook vaginal cervical ripening balloon (CCRB) with prostaglandin E2 (PGE2) insert for induction of labor in late pregnancy in primipara.Methods: We evaluated the effectiveness and safety of induction of labor using the improved Bishop score after CCRB or PGE2 administration, total stage of labor, hours until delivery (hours from placement of CCRB or PGE2 insert to parturition and delivery), delivery rate within 24 h, spontaneous delivery rate, successful induction rate, overstimulation syndrome, urgent delivery rate, pain scores, cesarean section rate, and outcomes related to delivery and perinatal morbidity, such as puerperal infection rate, total cost, satisfaction survey, and so on.Results: The improved Bishop Score and delivery rate within 24 h in the CCRB group were significantly higher than in the PGE2 group. The total stage of labor and hours until delivery in the CCRB group were significantly shorter than that in the PGE2 group. Rate of overstimulation syndrome and pain scores in the CCRB group were significantly lower than in the PGE2 group. Compared with the PGE2 group, the mean duration of hospitalization in the CCRB group was shorter and the total cost was less. No difference in satisfaction between the PGE2 and CCRB groups was observed.Conclusions: Compared with PGE2, CCRB reduced the total stage of labor, hours until delivery, pain scores, mean length of hospitalization, and total cost. CCRB increased the rate of delivery within 24 h with similar safety and maternal satisfaction compared with PGE2. [ABSTRACT FROM AUTHOR]

Background: Epidemiologic evidence suggests that physical activity benefits cognition, but results from randomized trials in sedentary individuals are limited and inconsistent.Objective: To evaluate the effects of physical activity on cognition among sedentary older adults.Objective: A systematic literature search for eligible studies published up to January 1, 2021, was performed on six international (PubMed, Cochrane Library, Web of Science, Sinomed, FMRS, and OVID) and three Chinese databases (Wanfang, China National Knowledge Infrastructure, and VIP). We estimated the effect of physical activity on the cognition of sedentary elderly by standardized mean differences (SMD) and 95% confidence intervals (CI) using a random-effects model. We evaluated publication bias using funnel plots and heterogeneity using I2 statistics. Subgroup analyses were conducted by baseline cognition, intervention duration, activity type, and country.Results: Seven randomized controlled trials (RCTs) comprising 321 (experimental group, 164; control group, 157) sedentary older adults were included in the meta-analysis. Physical activity significantly improved cognition in sedentary elderly adults compared with controls (SMD: 0.50, 95% CI:0.09-0.92). Subgroup analyses showed significant effects of baseline cognition impairment (SMD: 9.80, 95% CI: 5.81-13.80), intervention duration > 12 weeks (SMD: 2.85, 95% CI: 0.73-4.96), aerobic exercise (SMD: 0.74, CI: 0.19-1.29), and countries other than the United States (SMD: 10.50, 95% CI: 7.08-13.92).Conclusion: Physical activity might have a general positive effect on the cognition of sedentary older adults. Intervention > 12 weeks and aerobic exercise can effectively delay their cognitive decline; however, more rigorous RCTs are needed to support our findings. [ABSTRACT FROM AUTHOR]

Background: In 2003, China implemented free antiretroviral therapy (ART) for people living with HIV (PLHIV), establishing an eligibility threshold of CD4 < 200 cells/μl. Subsequently, the entry criteria were revised in 2012 (eligibility threshold: CD4 ≤ 350 cells/μl), 2014 (CD4 ≤ 500 cells/μl), and 2016 (treat-all). However, the impact of treat-all policy on HIV care and treatment indicators in China is unknown. We aimed to elucidate the immediate and long-term impact of the implementation of treat-all policy in China. Methods: Anonymized programmatic data on ART initiation and collection in PLHIV who newly started ART were retrieved between 1 January 2015 and 31 December 2019, from two provincial and municipal Centers for Disease Control and Prevention and ten major infectious disease hospitals specialized in HIV care in China. We used Poisson and quasi-Poisson segmented regression models to estimate the immediate and long-term impact of treat-all on three key indicators: monthly proportion of 30-day ART initiation, mean CD4 counts (cells/μl) at ART initiation, and mean estimated time from infection to diagnosis (year). We built separate models according to gender, age, route of transmission and region. Results: Monthly data on ART initiation and collection were available for 75,516 individuals [gender: 83.8% males; age: median 39 years, interquartile range (IQR): 28–53; region: 18.5% Northern China, 10.9% Northeastern China, 17.5% Southern China, 49.2% Southwestern China]. In the first month of treat-all, compared with the contemporaneous counterfactual, there was a significant increase in proportion of 30-day ART initiation [+ 12.6%, incidence rate ratio (IRR) = 1.126, 95% CI: 1.033–1.229; P = 0.007] and mean estimated time from infection to diagnosis (+ 7.0%, IRR = 1.070, 95% CI: 1.021–1.120; P = 0.004), while there was no significant change in mean CD4 at ART initiation (IRR = 0.990, 95% CI: 0.956–1.026; P = 0.585). By December 2019, the three outcomes were not significantly different from expected levels. In the stratified analysis, compared with the contemporaneous counterfactual, mean CD4 at ART initiation showed significant increases in Northern China (+ 3.3%, IRR = 1.033, 95% CI: 1.001–1.065; P = 0.041) and Northeastern China (+ 8.0%, IRR = 1.080, 95% CI: 1.003–1.164; P = 0.042) in the first month of treat-all; mean estimated time from infection to diagnosis showed significant increases in male (+ 5.6%, IRR = 1.056, 95% CI: 1.010–1.104; P = 0.016), female (+ 14.8%, IRR = 1.148, 95% CI: 1.062–1.240; P < 0.001), aged 26–35 (+ 5.3%, IRR = 1.053, 95% CI: 1.001–1.109; P = 0.048) and > 50 (+ 7.8%, IRR = 1.078, 95% CI: 1.000–1.161; P = 0.046), heterosexual transmission (+ 12.4%, IRR = 1.124, 95% CI: 1.042–1.213; P = 0.002) and Southwestern China (+ 12.9%, IRR = 1.129, 95% CI: 1.055–1.208; P < 0.001) in the first month of treat-all. Conclusions: The implementation of treat-all policy in China was associated with a positive effect on HIV care and treatment outcomes. To advance the work of rapid ART, efforts should be made to streamline the testing and ART initiation process, provide comprehensive support services, and address the issue of uneven distribution of medical resources.

Background: Several studies have reported that dietary and serum concentrations of vitamin D and cholesterol are correlated with mild cognitive impairment (MCI) and Alzheimer's disease (AD). However, little is known about whether 25 hydroxyvitamin D [25(OH)D], lipids, and oxysterols are related to cognitive function.Objective: This study sought to explore the relations between 25(OH)D, lipids, oxysterols, and cognitive function.Methods: In this study, about 209 MCI patients and 209 age- and gender-matched healthy controls were recruited from the Shanxi province of China (49.5% male; median [IQR] age: 63 [59-66] y). Serum concentrations of 25(OH)D, lipids, and oxysterols were measured using ultra-performance LC-MS. Cognitive performance was determined via comprehensive mental, verbal, and auditory cognitive tests. Dietary information was collected using a semiquantitative FFQ and 3 consecutive days of 24-h dietary recalls. Logistic regression analyses, Spearman's correlation, and partial correlation analyses were used to explore correlation between the variables.Results: Participants with vitamin D deficiency [serum 25(OH)D <20.0 ng/mL] were 3 times more likely to develop MCI compared to those with adequate vitamin D (≥30 ng/mL) concentrations. The AUC of 25(OH)D was 0.72 and the cut-off was 16.5 ng/mL (sensitivity:  50.3%,  specificity: 84.4%). Serum 25(OH)D concentrations were negatively correlated with total cholesterol (TC) (r = -0.19, P = 0.02), LDL-cholesterol (r = -0.17, P = 0.04), and 24S,25-epoxycholesterol (24S,25-epoxy-CHO) (r = -0.21, P = 0.01). Conversely, the Montreal Cognitive Assessment (MoCA) (r = 0.185, P < 0.001) and symbol digit modalities test (SDMT) (r = 0.11, P = 0.03) scores were positively correlated with serum 25(OH)D concentrations.Conclusion: The study identified significant differences in serum 25(OH)D concentrations between MCI patients and cognitive healthy controls, and there was a correlation between serum concentrations of 25(OH)D, lipids, and oxysterols and cognitive impairment among people. This study was registered at the Chinese Clinical Trial Registry as ChiCTR1900025452. [ABSTRACT FROM AUTHOR]

Suicide is a major public health concern, especially in prisoners. This study aims to investigate the prevalence of current suicidal ideation in a sample of Chinese female prisoners and examine the mediating role of negative emotions and social support in the link between childhood trauma and suicidal ideation. A cross-sectional study was conducted in five main jails of the district of Zhejiang province in China and a total of 626 female prisoners were surveyed by using cluster sampling. Childhood Trauma Questionnaire, Beck Depression Inventory, Beck Anxiety Inventory, Beck Hopelessness Scale and Multidimensional Scale of Perceived Social Support were applied. The estimated prevalence of current suicide ideation among Chinese female prisoners was 33.4%. Structural equation modeling analyses revealed that social support and negative emotions acted as chain mediators between childhood trauma and current suicidal ideation. Results emphasize the importance of stress-diathesis theory of suicidality in understanding the possible mechanisms underlying the relationship between childhood trauma and suicidal ideation among female prisoners. • Suicide ideation is much common among Chinese female prisoners. • Childhood trauma is positively associated to suicidal ideation. • This association is mediated by negative emotions and social support.

This study investigated the effect of migrant children's perceived discrimination on their social adaptation and the moderating effect of their city identity. In addition, differences in the relationships among the aforementioned variables were compared across two school types in terms of public schools and privately operated migrant schools. A cluster sampling method was used to survey 410 junior high school students in China using the Social Adaptation Assessment Questionnaire, the Perceived Discrimination Questionnaire for Individuals, and the City Identity Questionnaire as measures. Results showed that perceived discrimination significantly and negatively affected the social adaptation of migrant children. The relationship between perceived discrimination and social adaptation was moderated by the city identity of migrant children in private schools but not by those in public schools. Under the condition of high or medium city identity, discrimination negatively predicts social adaptation; under the condition of low city identity, however, discrimination does not predict social adaptation. In conclusion, perceived discrimination is an important factor regarding the social adaptation of migrant children, and their relationships vary by different types of city identity and schools.

Objective. To assess the value of bronchoscopy in the diagnosis and treatment of primary tracheobronchial amyloidosis (TBA), in order to reduce misdiagnosis rates and improve prognosis. Methods. Clinical data of 107 patients with TBA reported from 1981 to 2015 in China were retrospectively analyzed for clinical features, bronchoscopic manifestations, pathologies, treatments, and outcomes. Results. 105 of 107 TBA patients were pathologically confirmed by bronchoscopy. Main bronchoscopic manifestations of TBA were single or multiple nodules and masses within tracheobronchial lumens; local or diffuse luminal stenosis and obstruction; luminal wall thickening and rigidity; rough or uneven inner luminal walls; congestion and edema of mucosa, which was friable and prone to bleeding upon touch; and so forth. 53 patients were treated with bronchoscopic interventions, like Nd-YAG laser, high-frequency electrotome cautery, freezing, resection, clamping, argon plasma coagulation (APC), microwaving, stent implantation, drug spraying, and other treatments. 51 patients improved, 1 patient worsened, and 1 died. Conclusion. Bronchoscopic biopsy is the primary means of diagnosing TBA. A variety of bronchoscopic interventions have good short-term effects on TBA. Bronchoscopy has important value in the diagnosis, severity assessment, treatment, efficacy evaluation, and prognosis of TBA. [ABSTRACT FROM AUTHOR]
