ABSTRACT
Background & aim: The coronavirus disease 2019 (COVID-19) pandemic has affected the life and work of people worldwide. The present study aimed to evaluate the rhythm disruptions of life, work, and entertainment, and their associations with the psychological impacts during the initial phase of the COVID-19 pandemic. Method: A cross-sectional study was conducted from the 10th to 17th March 2020 in China. A structured e-questionnaire containing general information, the Chinese version of Brief Social Rhythm Scale, and Zung's self-rating scales of depression and anxiety (SDS and SAS) was posted and collected online through a public media (i.e. EQxiu online questionnaire platform). Scores in sleeping, getting up, and socializing (SGS) rhythm and eating, physical practice, and entertainment (EPE) rhythm were compared among and between participants with different sociodemographic backgrounds including gender, age, education, current occupation, annual income, health status, and chronic disease status. Correlations of SDS and SAS with SGS-scale and EPE-scale were also analyzed. Results: Overall, 5854 participants were included. There were significant differences in the scores of SGS-scale and EPE-scale among people with different sociodemographic backgrounds. The scores were significantly higher in the groups with female gender, low education level, lower or higher than average income, poor health status, ages of 26-30 years or older than 61 years, nurses and subjects with divorce or widow status. There were also significant differences in SAS and SDS scores among people with different sociodemographic backgrounds (all P< 0.05). The overall prevalence of depression and anxiety was 24.3% and 12.6%, respectively, with nurses having the highest rates of depression (32.94%) and anxiety (18.98%) among the different occupational groups. SGS-scale was moderately correlated with SDS and SAS, and disruption of SGS rhythm was an independent risk factor for depression and anxiety. Conclusion: Social rhythm disruption was independently associated with depression and anxiety. Interventions should be applied to people vulnerable to the rhythm disruption during the COVID-19 pandemic. (PsycInfo Database Record (c) 2022 APA, all rights reserved)
ABSTRACT
BACKGROUND and OBJECTIVE The rhythms of life, work and entertainment behaviours are considered as the external behavioural manifestations of biological rhythm.To evaluate the distinctive disrupted rhythms of behaviours and their associations with mental health problems in people with different backgrounds under the stress of COVID-19 epidemic.SUBJECTS AND METHODS A cross-sectional study was conducted from 10-17 March 2020 under the stress of COVID-19 epidemic.A structured e-questionnaire containing general information,rhythm scale(subscale1 for life-work rhythms and subscale2 for entertainment rhythm) and Zung's self-rating depression and anxiety scale(SDS and SAS) were filled and the data were analysed.RESULTS Overall 5854 participants were included.Significant differences were found in rhythm, SDS and SAS scores among people with different backgrounds (all P<0.05). Subjects with female gender and poor health status were mostly suffered from disrupted rhythms of life- work-entertainment behaviours, combined with depression and anxiety. Nurses and subjects being divorced or with chronic disease with psychosomatic diseases were mostly suffered from disrupted rhythms of life-work behaviours, combined with depression and anxiety. Subjects with aged 26-30 years, or annual income of 50,000-100,000CY were mostly suffered from disrupted rhythms of life-work combined with depression. Subjects with income over 300,000CY were mostly suffered from disrupted rhythm of entertainment combined with anxiety.The prevalence rates of depression and anxiety in people with the high-scores of rhythm disruption increased by 34.50% and 47.16%, respectively, compared with those with low-scores.People with the high-scores of rhythm disruption had higher SDS and SAS scores, compared to those with low scores (all P<0.001). The independent related factors of disrupted rhythms included gender,age,marital status, health status,annual income and chronic diseases with psychosomatic diseases using logistic regression.The disrupted rhythms of life and work behaviours was positively correlated with both SDS and SAS scores.CONCLUSIONS The disrupted rhythms of life, work and entertainment behaviours were closely associated with mental health problems.The disrupted rhythms of behaviours are frequent and fluxible,triggering more severe mental health problems under the stress of COVID-19 epidemic.The physicians should be aware of their importance when evaluating their interviewees or patients’ mental health and achieving maximization of therapeutic efficacy by integrating the intervention of circadian rhythm and its behaviour.

WHO has declared COVID-19 a pandemic with more than 300,000 confirmed cases and more than 14,000 deaths. There is urgent need for accurate and rapid diagnostic kits. Here we report the development and validation of a COVID-19/SARS-CoV-2 S1 serology ELISA kit for the detection of total anti-virus antibody (IgG+IgM) titers in sera from either the general population or patients suspected to be infected. For indirect ELISA, CHO-expressed recombinant full length SARS-CoV-2-S1 protein with 6*His tag was used as the coating antigen to capture the SARS-CoV-2-S1 antibodies specifically. The specificity of the ELISA kit was determined to be 97.5%, as examined against total 412 normal human sera including 257 samples collected prior to the outbreak and 155 collected during the outbreak. The sensitivity of the ELISA kit was determined to be 97.5% by testing against 69 samples from hospitalized and/or recovered COVID-19 patients. The overall accuracy rate reached 97.3%. Most importantly, in one case study, the ELISA test kit was able to identify an infected person who had previously been quarantined for 14 days after coming into contact with a confirmed COVID-19 patient, and discharged after testing negative twice by nucleic acid test. With the assays developed here, we can screen millions of medical staffs in the hospitals and people in residential complex, schools, public transportations, and business parks in the epidemic centers of the outbreaks to fish out the "innocent viral spreaders", and help to stop the further spreading of the virus.
