ObjectiveStudies of sleep duration in relation to the risk of sensory impairments other than dementia are scarce. Little is known about the associations between sleep duration and sensory impairments in China. This study aims to explore the associations between sleep duration and single or dual sensory impairments (visual and/or hearing).MethodsThis cross-sectional study used the data from 17,668 respondents were drawn from the 2018 survey of the China Health and Retirement Longitudinal Study (CHARLS), an ongoing national longitudinal study of Chinese adults aged 45 years and above. The duration of sleep per night was obtained from face-to-face interviews. The presence of sensory impairments was measured by self-reported visual and hearing functions. Multivariable generalized linear models (GLM) with binomial family and log link to assess the associations between sleep duration and sensory impairments.ResultsOf the 17,668 respondents, 8,396 (47.5%) were men. The mean (SD) age was 62.5 (10.0) years old. Respondents with short (≤ 4, 5 h per night) sleep duration had a significantly higher risk of visual, hearing and dual sensory impairments than those who slept for 7 h per night after adjusting for covariates (P < 0.05). Meanwhile, respondents who slept for 6 h per night had a higher risk of hearing impairment (P = 0.005). Further analysis suggested a U-shaped association between sleep duration and sensory impairments. When sleep duration fell below 8 h, increased sleep duration was associated with a significantly lower risk of visual (OR, 0.93; 95%CI, 0.88–0.98; P = 0.006), hearing (OR, 0.89; 95% CI, 0.86–0.93; P < 0.001), and dual (OR, 0.90; 95% CI, 0.87–0.94; P < 0.001) impairments. When sleep duration exceeded 8 h, the risk of visual (OR, 1.09; 95% CI, 1.00–1.19; P = 0.048), hearing (OR, 1.04; 95% CI, 0.97–1.11; P = 0.269), and dual (OR, 1.07; 95% CI, 1.00–1.14; P = 0.044) impairments would increase facing prolonged sleep duration. Women and the elderly aged over 60 years old were more sensitive to short sleep duration and experienced a higher risk of sensory impairments.ConclusionIn this study, short sleep duration was associated with a higher risk of visual and hearing impairments. Future studies are needed to examine the mechanisms of the associations between sleep duration and sensory impairments.

Objective: At the global level, a multi-country outbreak of monkeypox has attracted global attention. The purpose of this study is to explore the growing contribution of global research on monkeypox. Methods: Publications related to monkeypox were retrieved from PubMed and Web of Science. Bibliometric analyses were conducted by VOSviewer and CiteSpace software to generate network maps, evaluate hot topics in the field, and identify cooperation patterns between different authors and countries. Results: A total of 1822 publications were retrieved to reflect the global overall monkeypox research output, including clinical trials, systematic reviews, case reports, and laboratory studies. The most productive country and institution were respectively the United States and Centers for Disease Control and Prevention—USA (CDC). The top three authors with the highest number of publications were all from the CDC. Research hotspots included some monkeypox-related diseases, such as smallpox and vaccinia, and the prevention and treatment of monkeypox diseases, such as antiviral drugs and smallpox vaccines. Research fronts included real-time PCR, immune evasion, animal models, and monkeypox outbreak countries (Democratic Republic of Congo and others). Conclusions: Research on monkeypox is mainly carried out from the aspects of its source, transmission route, virus prevalence, and prevention and control measures. Controlling monkeypox is a global responsibility, and the future research into monkeypox control methods is suggested to focus on more than vaccines.

Objective: To investigate the relationships between sleep duration and depression among middle-aged and older adults in China. Methods: This study used the data of 17,744 respondents from the 2018 China Health and Retirement Longitudinal Study (CHARLS), an ongoing national longitudinal survey of Chinese adults aged 45 years and above. Self-reported sleep duration per night was obtained from face-to-face interviews. Depression was evaluated using the 10-item Center for Epidemiological Studies-Depression scale (CES-D 10). The multivariable generalized linear model (GLM) was adopted to estimate the associations between sleep duration and depression. Results: Of the 17,744 respondents, 8425 (47.5%) were men. The mean (SD) age was 62.6 (10.0) years old. Respondents with short (≤4, 5 h per night) sleep duration had a higher risk of depression [odds ratio (OR): 2.77, 95% confidence interval (CI): 2.35–3.27), p < 0.001; OR: 1.65, 95% CI: 1.38–1.98, p < 0.001] compared with those slept for 7 h per night after adjusting for covariates. Long sleep duration (8, 9, ≥10) had no significant risk for depression. Restricted cubic splines analysis suggested that when sleep duration fell below 9 h, increased sleep duration was associated with a significantly lower risk of depression (OR: 0.82, 95% CI: 0.79–0.84, p < 0.001). When sleep duration exceeded 9 h, the risk of depression (OR: 1.03, 95% CI: 0.94–1.14, p = 0.512) would not increase significantly facing prolonged sleep duration. Conclusions: Short sleep duration was associated with depressive symptoms among middle-aged and older adults in China. Future studies are needed to focus on examining the cause-effect relationship between sleep duration and depression.

Background: Monkeypox, a zoonotic disease caused by an Orthopoxvirus, presents an etiology similar to smallpox in humans. Currently, there are no licensed treatments for human monkeypox, so clear and urgent research on its prophylaxis and treatment is needed.Objective: The purpose of this study was to explore the evidence of Chinese medicine for contagious pox-like viral diseases and provide suggestions for the multi-country outbreak management of monkeypox.Methods: The review was registered on INPLASY (INPLASY202270013). Ancient classics in China and clinical trials involving randomized controlled trials , non-RCTs, and comparative observational studies of CM on the prevention and treatment of monkeypox, smallpox, measles, varicella, and rubella were retrieved from the Chinese Medical Code (fifth edition), Database of China Ancient Medicine, PubMed, the Cochrane Library, China National Knowledge Infrastructure, Chongqing VIP, Wanfang, Google Scholar, International Clinical Trial Registry Platform, and Chinese Clinical Trial Registry until 6 July 2022. Both quantitative and qualitative methods were applied to present the data collected.Results: The use of CM to control contagious pox-like viral diseases was traced back to ancient Chinese practice cited in Huangdi’s Internal Classic, where the pathogen was recorded nearly two thousand years back. There were 85 articles (36 RCTs, eight non-RCTs, one cohort study, and 40 case series) that met the inclusion criteria, of which 39 studies were for measles, 38 for varicella, and eight for rubella. Compared with Western medicine for contagious pox-like viral diseases, CM combined with Western medicine showed significant improvements in fever clearance time (mean difference, −1.42 days; 95% CI, −1.89 to −0.95; 10 RCTs), rash/pox extinction time (MD, −1.71 days; 95% CI, −2.65 to −0.76; six RCTs), and rash/pox scab time (MD, −1.57 days; 95% CI, −1.94 to −1.19; five RCTs). When compared with Western medicine, CM alone could reduce the time of rash/pox extinction and fever clearance. Chinese herbal formulas, including modified Yinqiao powder, modified Xijiao Dihaung decoction, modified Qingjie Toubiao decoction, and modified Shengma Gegen decoction, were frequently applied to treat pox-like viral diseases and also showed significant effects in shortening the time of fever clearance, rash/pox extinction, and rash/pox scabs. Compared with Western medicine (placental globulin) or no intervention, eight non-randomized trials and observational studies on the prevention of contagious pox-like viral diseases showed a significant preventive effect of Leiji powder among high-risk populations.Conclusion: Based on historical records and clinical studies of CM in managing contagious pox-like viral diseases, some botanical drugs could be an alternative approach for treating and preventing human monkeypox. Prospective, rigorous clinical trials are urgently needed to confirm the potential preventive and treatment effect of Chinese herbal formulas.Systematic Review Registration: [https://inplasy.com/], identifier [INPLASY202270013].
