Prevalence and influencing factors of depressive symptoms among rural-to-urban migrant workers in China: A systematic review and meta-analysis.

BACKGROUND: Rural-to-urban migrant workers are a large group in China, and they are often more prone to mental health problems, especially depression. We expected to use meta-analysis to estimate the prevalence of depressive symptoms and the influencing factors of depressive symptoms among rural-to-urban migrant workers in China. METHODS: PubMed, Web of Science, Embase, Scopus, CINAHL Complete, PsycARTICLES, CNKI, Wan Fang, CBM, and Cochrane were searched on October 16, 2021. The data were analyzed using OR and random effect model in Revman5.3 and STATA 15 Software. RESULTS: We included 30 studies involving 43,884 rural-to-urban migrant workers. The prevalence of depressive symptoms among rural-to-urban migrant workers in China was 0.28 (95% CI:0.22, 0.34); Results of the meta-analysis showed that working hours, sleep status, self-rated health, financial condition, job satisfaction, marriage, and social support were correlated with depressive symptoms. LIMITATIONS: The systematic review and meta-analysis included only cross-sectional studies, and more types of original studies on depressive symptoms of rural-to-urban migrant workers in China should be carried out in the future. CONCLUSION: The prevalence of depressive symptoms among rural-to-urban migrant workers in China is 28%. Government departments can intervene early in the process to promote the mental health of this group based on influencing factors of depressive symptoms among rural-to-urban migrant workers in China.

Metabolic associated fatty liver disease increases the severity of COVID-19: A meta-analysis.

BACKGROUND: The association between metabolic-associated fatty liver disease (MAFLD) and disease progression in patients with the coronavirus disease 2019 (COVID-19) are unclear. AIMS: To explore the association between MAFLD and the severity of COVID-19 by meta-analysis. METHODS: We conducted a literature search using PubMed, EMBASE, Medline (OVID), and MedRxiv from inception to July 6, 2020. Newcastle-Ottawa Scale (NOS) and Stata 14.0 were used for quality assessment of included studies as well as for performing a pooled analysis. RESULTS: A total of 6 studies with 1,293 participants were included after screening. Four studies reported the prevalence of MAFLD patients with COVID-19, with a pooled prevalence of 0.31 for MAFLD (95CI 0.28, 0.35, I2 = 38.8%, P = 0.179). MAFLD increased the risk of COVID-19 disease severity, with a pooled OR of 2.93 (95CI 1.87, 4.60, I2 = 34.3%, P = 0.166). CONCLUSION: In this meta-analysis, we found that a high percentage of patients with COVID-19 had MAFLD. Meanwhile, MAFLD increased the risk of disease progression among patients with COVID-19. Thus, better intensive care and monitoring are needed for MAFLD patients infected by SARS-COV-2.

Prevalence and clinical outcomes of cardiac injury in patients with COVID-19: A systematic review and meta-analysis.

BACKGROUND AND AIMS: Emerging data have linked the presence of cardiac injury with a worse prognosis in novel coronavirus disease 2019 (COVID-19) patients. However, available data cannot clearly characterize the correlation between cardiac injury and COVID-19. Thus, we conducted a meta-analysis of recent studies to 1) explore the prevalence of cardiac injury in different types of COVID-19 patients and 2) evaluate the association between cardiac injury and worse prognosis (severe disease, admission to ICU, and mortality) in patients with COVID-19. METHODS AND RESULTS: Literature search was conducted through PubMed, the Cochrane Library, Embase, and MedRxiv databases. A meta-analysis was performed with Stata 14.0. A fixed-effects model was used if the I2 values ≤ 50%, otherwise the random-effects model was performed. The prevalence of cardiac injury was 19% (95% CI: 0.15-0.22, and p < 0.001) in total COVID-19 patients, 36% (95% CI: 0.25-0.47, and p < 0.001) in severe COVID-19 patients, and 48% (95% CI: 0.30-0.66, and p < 0.001) in non-survivors. Furthermore, cardiac injury was found to be associated with a significant increase in the risk of poor outcomes with a pooled effect size (ES) of 8.46 (95% CI: 3.76-19.06, and p = 0.062), severe disease with an ES of 3.54 (95% CI: 2.25-5.58, and p < 0.001), admission to ICU with an ES of 5.03 (95% CI: 2.69-9.39, and p < 0.001), and mortality with an ES of 4.99 (95% CI: 3.38-7.37, and p < 0.001). CONCLUSIONS: The prevalence of cardiac injury was greatly increased in COVID-19 patients, particularly in patients with severe disease and non-survivors. COVID-19 patients with cardiac injury are more likely to be associated with poor outcomes, severity of disease, admission to ICU, and mortality.

Comparative review of respiratory diseases caused by coronaviruses and influenza A viruses during epidemic season.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to sweep the world, causing infection of millions and death of hundreds of thousands. The respiratory disease that it caused, COVID-19 (stands for coronavirus disease in 2019), has similar clinical symptoms with other two CoV diseases, severe acute respiratory syndrome and Middle East respiratory syndrome (SARS and MERS), of which causative viruses are SARS-CoV and MERS-CoV, respectively. These three CoVs resulting diseases also share many clinical symptoms with other respiratory diseases caused by influenza A viruses (IAVs). Since both CoVs and IAVs are general pathogens responsible for seasonal cold, in the next few months, during the changing of seasons, clinicians and public heath may have to distinguish COVID-19 pneumonia from other kinds of viral pneumonia. This is a discussion and comparison of the virus structures, transmission characteristics, clinical symptoms, diagnosis, pathological changes, treatment and prevention of the two kinds of viruses, CoVs and IAVs. It hopes to provide information for practitioners in the medical field during the epidemic season.
