Background The present study aimed 1) to examine the effects of epidemic-related job stressors, perceived social support and organizational support on the burnout and well-being of Chinese healthcare workers in the period of COVID-19 regular epidemic prevention and control and 2) to investigate the moderating effects of social support and organizational support on the relationship between job stressors and burnout and well-being within the theoretical framework of the Job Demands-Resources (JD-R) model. Methods A sample of healthcare workers (N = 3477) from 22 hospitals in Beijing, China participated in the cross-sectional investigation in October 2020 and reported epidemic-related job stressors, perceived social support, organizational support, burnout, anxiety and depression symptoms. Results 1) Medical doctors, females, people aged from 30 to 50, and those who worked in the second line during the pandemic reported higher scores of psychological symptoms and burnout in the period of regular epidemic prevention and control; 2) Epidemic-related job stressors positively predicted burnout, anxiety, and depression among healthcare workers; 3) Perceived social support and organizational support were negatively related to reported burnout, anxiety and depression symptoms; 4) Social support reduced the adverse effects of epidemic-related job stressors on anxiety and depression but enhanced the association between stressors and burnout; 5) Organizational support mitigated the adverse effects of epidemic-related job stressors on depression. Conclusion The results shed light on preventing burnout and enhancing the psychological well-being of healthcare workers under epidemic prevention and control measures by reducing epidemic-related job stressors and strengthening personal and organizational support systems.

Inspired by the interactions between platelets and tumor cells, multiscaled cytophilic interfaces are fabricated by assembling platelet‐mimicking microspheres via oxidative polymerization of polyaniline nanohairs through transverse nanochannels in the shells of hollow polystyrene microspheres, and modifying specific recognition molecules. This interface realizes efficient tumor‐cell recognition and isolation from artificial blood, suggesting a new platform for metastasis diagnosis and cancer treatment.

Introduction This study aimed to examine the mediating role of sleep quality in the association of problematic internet use (PIU) and problematic gaming with psychological distress among college students in China. Methods Data of 1040 full-time students from multiple colleges in China were examined. Respondents were asked about their internet use and gaming behaviors, sleep quality, psychological distress, and sociodemographic characteristics. The mediating role of sleep quality in the PIU- and problematic gaming-psychological distress link was examined respectively. Results PIU was associated with decreased sleep quality (r = .32, p < .001) and increased psychological distress (r = .46, p < .001). Problematic gaming was also associated with decreased sleep quality (r = .22, p < .001) and increased psychological distress (r = .46, p < .001). Sleep quality accounted for 23.5% of the indirect effect of PIU on psychological distress, and 17.9% of the indirect effect of problematic gaming on psychological distress. Conclusions Sleep quality had a meaningful mediating effect on the PIU-psychological distress link, but only exerted a small mediating effect on the problematic gaming-psychological distress link. In addition to promoting healthy internet usage, strategies aimed at mitigating the negative effect of excessive internet use on psychological health might benefit from those aimed at improving sleep quality.

Background: Post-traumatic stress disorder (PTSD) is the most common psychiatric sequelae among novel coronavirus disease (COVID-19) patients. The aim of this study was to determine the prevalence of PTSD symptoms, PTSD-related factors, and its relationship with quality of life at long-term follow-up in hospitalized COVID-19 survivors.Methods: A cross-sectional study was undertaken to evaluate the health consequences of hospitalized COVID-19 survivors. All participants were interviewed face-to-face through a series of questionnaires: a researcher-developed symptom questionnaire, the Post-traumatic Stress Disorder Checklist–Civilian Version, the Generalized Anxiety Disorder 7-item, and the 36-item Short Form.Results: A total of 574 participants were enrolled with an average age of 57 years. The median follow-up time post-discharge was 193.9 days (SD = 15.32). Among the participants, 77.9% of survivors presented with at least one symptom, where fatigue or muscle weakness (47.9%) was reported the most frequently, followed by chest distress (29.4%) and sleep difficulty (29.4%). The prevalence of PTSD was 11.15% [95% confidence interval (CI): 8.56, 13.73] with a cut-off score of 44. Factors such as respiratory symptoms [odds ratio (OR): 3.53; 95% CI: 1.68–7.42], anxiety (OR: 14.64; 95% CI: 7.09–30.21), and sleep difficulty (OR: 2.17; 95% CI: 1.14–4.16) were positively related to PTSD. Those COVID-19 survivors with potential PTSD had significantly lower quality of life than those without (P &lt; 0.05).Conclusion: Our study illustrated that a significant number of COVID-19 survivors were suffering from physical or mental distress to varying degrees at 6 months post-discharge. People with PTSD were more likely to experience persistent respiratory symptoms and sleep difficulty, as well as anxiety and a decreased quality of life. Such survivors require greater attention to their mental health, particularly the PTSD symptoms at the early phase, which may play an important role in the recovery of both the physical and psychological health of COVID-19 survivors.

Two hundred and thirteen Chinese adolescents (103 females; mean age = 12.18 years) completed a survey one year before (Wave 1) and five months after the COVID‐19 outbreak (Wave 2). Path analysis revealed that after controlling for adolescents’ emotional maladjustment at Wave 1, perceived parental supportive reactions to adolescents’ negative emotions at Wave 1 predicted adolescents’ greater use of approach coping and less use of avoidance coping at Wave 2, which in turn, was associated with less emotional maladjustment at Wave 2; conversely, perceived parental nonsupportive reactions at Wave 1 predicted adolescents’ greater use of avoidance coping at Wave 2, which in turn, was associated with greater emotional maladjustment at Wave 2. The findings were similar for mothers and fathers.

We examined correlates of mental health conditions among family members and explored the effects of mothers' and fathers' mental health and family functioning on their child's behavioral problems. Participants were 119 couples in China, of whom the majority were parents in 1-child families. These parents reported their own anxiety and depression symptoms, behavioral problems of their child, and perceived family functioning. Results indicated that the mental health condition of the father, mother, and child were closely correlated, and that parental mental health was positively correlated with family functioning. Further, the couples had relatively high consistency in their ratings of family functioning and the child's behavioral problems, with rating discrepancies being positively correlated with mental health conditions. Finally, paternal mental health made a unique contribution to prediction of the child's behavioral problems when father-reported data were used, but this effect was not significant when the mother-reported data were applied.

Addition arithmetic design plays a crucial role in high performance digital systems. The paper proposes a systematic method to formalize and verify adders in a formal proof assistant COQ. The proposed approach succeeds in formalizing the gate-level implementations and verifying the functional correctness of the most important adders of interest in industry, in a faithful, scalable, and modularized way. The methodology can be extended to other adder architectures as well.
