Objective: The COVID-19 pandemic has had a significant impact on the burnout and mental health of medical staff. This meta-analysis aims to provide additional (and updated) evidence related to burnout and mental health problems among medical staff using a broader data pool. Design: Systematic review and meta-analysis. Data sources: PubMed, Embase, Cochrane Library, CNKI, Wanfang data and three preprint databases (SSRN, bioRxiv and medRxiv) were searched from 1 January 2020 to 17 May 2021. Eligibility criteria: We included observational studies investigating the prevalence of burnout and mental health problems among medical staff during the COVID-19 pandemic, including cross-sectional study, cohort study and case–control study. Data extraction and synthesis: Two independent reviewers used a self-designed form to extract the primary data. The Joanna Briggs Institute quality appraisal tool was used to assess the quality of selected studies. Heterogeneity among studies was assessed by I² statistic. A random-effects model was used to pool the prevalence. Subgroup analysis was performed to explore between-group differences. Results: 250 studies were included, with a sample of 292 230 participants from 46 countries. The pooled prevalence of burnout, anxiety, depression, insomnia, stress, post-traumatic stress disorder symptoms and somatic symptoms was 43.6% (95% CI 36.3% to 51.2%), 37.1% (95% CI 34.7% to 39.7%), 37.6% (95% CI 35.0% to 40.4%), 43.7% (95% CI 39.1% to 48.5%), 41.3% (95% CI 35.1% to 47.9%), 30.6% (95% CI 23.6% to 38.5%) and 25.0% (95% CI 16.7% to 35.6%), respectively. Subgroup analysis showed a higher prevalence of anxiety, depression and insomnia in frontline workers than in non-frontline workers, and a higher prevalence of anxiety in females than males. Mild cases accounted for the most significant proportion of the outcomes except for stress. Conclusions: This study highlights that identifying the risks of burnout and mental health problems and adopting preventive interventions are priorities for policymakers and medical staff to avoid long-term occupational, health and social impacts.

Aim: To examine the demographic and work characteristics of mental health workers associated with burnout during the COVID‐19 epidemic and to examine the relationship between burnout and humanistic care ability.Design: Online cross‐sectional design.Methods: 270 mental health workers in Chongqing, China, were recruited via WeChat from 1 to 31 December 2020. Online self‐administered questionnaires were used to collect data. Data were analyzed by t‐tests and one‐way analyses of variance, Pearson's correlation analysis, and multiple linear regression analysis.Results: During the COVID‐19 pandemic, mental health workers had a high prevalence of burnout and a low level of humanistic care ability. Work factors including profession, work shift, work pressure, work‐family conflict, practice environment satisfaction, salary satisfaction, and humanistic care ability were significantly associated with burnout and its subdimension.

To explore the relationship among a growth mindset, well-being and learning engagement of nursing students and the mediating effect of well-being. Reduced well-being and learning burnout are common among nursing students. From the perspective of positive psychology, a positive education can help students obtain well-being, improve their academic performance and be actively involved in learning. The core of positive education is a growth mindset. However, few studies have explored the causal relationship among a growth mindset, learning engagement and well-being. Correlational design based on cross-sectional data from a multicenter survey study. A web-based survey was completed by 1065 nursing students from 5 schools in China between August 2022 and December 2022. The Growth Mindset Scale, the PERMA profiler and the Learning Engagement Scale were used to investigate the effect of a growth mindset on learning engagement and the mediating effect of well-being. Both a growth mindset (r = 0.272, p < 0.01) and well-being (r = 0.693, p < 0.01) were positively correlated with learning engagement, and a growth mindset (r = 0.363, p < 0.01) was positively correlated with well-being. Well-being completely mediated the relationship between a growth mindset and learning engagement. The growth mindset and well-being of nursing students are related to learning engagement. Therefore, schools can change students' thinking mode by carrying out positive education to enable students to acquire the ability to maintain their well-being and to improve their well-being and learning engagement.

Orofacial myofunctional therapy (OMT) is one of the therapeutic methods for neuromuscular re-education and has been considered as one of the auxiliary methods for obstructive sleep apnea hypopnea syndrome (OSAHS) and orthodontic treatment. There is a dearth of comprehensive analysis of OMT’s effects on muscle morphology and function. This systematic review examines the literature on the craniomaxillofacial effects of OMT in children with OSAHS. This systematic analysis was carried out using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standards, and the research was scanned using PICO principles. A total of 1776 articles were retrieved within a limited time, with 146 papers accepted for full-text perusing following preliminary inspection and 9 of those ultimately included in the qualitative analysis. Three studies were rated as having a severe bias risk, and five studies were rated as having a moderate bias risk. Improvement in craniofacial function or morphology was observed in most of the 693 children. OMT can improve the function or morphology of the craniofacial surface of children with OSAHS, and its effect becomes more significant as the duration of the intervention increases and compliance improves. In the majority of the 693 infants, improvements in craniofacial function or morphology were seen. The function or morphology of a kid’s craniofacial surface can be improved with OMT, and as the duration of the intervention lengthens and compliance rises, the impact becomes more pronounced.

Background: Patients with heart failure with preserved ejection fraction (HFpEF) are more often female, but gender differences in psychological distress in patients with HFpEF have not been determined. Objective: We aimed to compare anxiety, depression, insomnia, and quality of life (QoL) between women and men with HFpEF. Methods: A total of 263 consecutive hospitalized patients with HFpEF were enrolled in a multicenter study. Demographic and clinical characteristics were recorded. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS), insomnia was assessed by the Insomnia Severity Index and Pittsburgh Sleep Quality Index, and QoL was assessed by the Kansas City Cardiomyopathy Questionnaire. Results: Women accounted for 59% and men accounted for 41% of the patients with HFpEF. Women and men had similar New York Heart Association functional class and N-terminal pro–brain natriuretic peptide levels. Between women and men with HFpEF, similar depression prevalence (HADS-D: 4.9 ± 3.7 vs 4.1 ± 3.6, P = .222), insomnia severity (Insomnia Severity Index: 9.3 ± 6.4 vs 8.0 ± 6.5, P = .120), and QoL (Kansas City Cardiomyopathy Questionnaire: 46.6 ± 12.6 vs 47.6 ± 12.7, P = .738) were found when adjusting for potential confounders. Women had more severe anxiety (HADS-Anxiety: 2.4 ± 2.9 vs 1.6 ± 2.3, P = .025) and worse sleep quality (Pittsburgh Sleep Quality Index: 9.9 ± 4.6 vs 8.7 ± 4.5, P = .046) compared with men after adjustment. Conclusions: There were no gender differences in depression, insomnia, and QoL in patients with HFpEF when adjusting for confounders. Women with HFpEF suffered more severe anxiety and sleep quality than men after adjustment. Thus, it is recommended that psychological distress in patients with HFpEF be assessed in clinical practice, and gender differences taken into consideration.
