ABSTRACT
OBJECTIVE: Explore the relevant evidence about stress-related cognitive appraisal and coping strategies among registered nurses in the emergency department (EDRNs) coping with the COVID-19 pandemic. METHODS: This scoping review followed the methodological framework of Arksey and O'Malley to map relevant evidence and synthesize the findings. We searched PubMed, EMBASE, CINAHL, Web of Science, and Scopus electronic databases for related studies from inception through February 2, 2022. This review further conducted study selection based on the PRISMA flow diagram and applied Lazarus and Folkman's Psychological Stress and Coping Theory to systematically organize, summarize, and report the findings. FINDINGS: Sixteen studies were included for synthesis. Most of the studies showed that the majority of EDRNs were overwhelmed by the COVID-19 pandemic. Depression, triaging distress, physical exhaustion, and intention to leave ED nursing were cited as major threats to their wellness. Additionally, comprehensive training, a modified triage system, a safe workplace, psychological support, promotion of resilience, and accepting responsibility may help EDRNs cope with pandemic-related challenges effectively. CONCLUSION: The long-lasting pandemic has affected the physical and mental health of EDRNs because they have increased their effort to respond to the outbreak with dynamically adjusted strategies. Future research should address a modified triage system, prolonged psychological issues, emergency healthcare quality, and solutions facing EDRNs during the COVID-19 or related future pandemics. CLINICAL RELEVANCE: EDRNs have experienced physical and psychological challenges during the pandemic. The ED administrators need to take action to ensure EDRNs' safety in the workplace, an up-to-date triage system, and mental health of frontline nurses to provide high-quality emergency care for combating COVID-19.
ABSTRACT
Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT04365634. Context: Diabetes mellitus was associated with increased severity and mortality of disease in COVID-19 pneumonia. So far the effect of type 2 diabetes (T2DM) or hyperglycemia on the immune system among COVID-19 disease has remained unclear. Objective: We aim to explore the clinical and immunological features of type 2 diabetes mellitus (T2DM) among COVID-19 patients. Design and Methods: In this retrospective study, the clinical and immunological characteristics of 306 hospitalized confirmed COVID-19 patients (including 129 diabetic and 177 non-diabetic patients) were analyzed. The serum concentrations of laboratory parameters including cytokines and numbers of immune cells were measured and compared between diabetic and non-diabetic groups. Results: Compared with non-diabetic group, diabetic cases more frequently had lymphopenia and hyperglycemia, with higher levels of urea nitrogen, myoglobin, D-dimer and ferritin. Diabetic cases indicated the obviously elevated mortality and the higher levels of cytokines IL-2R, IL-6, IL-8, IL-10, and TNF-α, as well as the distinctly reduced Th1/Th2 cytokines ratios compared with non-diabetic cases. The longitudinal assays showed that compared to that at week 1, the levels of IL-6 and IL-8 were significantly elevated at week 2 after admission in non-survivors of diabetic cases, whereas there were greatly reductions from week 1 to week 2 in survivors of diabetic cases. Compared with survival diabetic patients, non-survival diabetic cases displayed distinct higher serum concentrations of IL-2R, IL-6, IL-8, IL-10, TNF-α, and lower Th1/Th2 cytokines ratios at week 2. Samples from a subset of participants were evaluated by flow cytometry for the immune cells. The counts of peripheral total T lymphocytes, CD4+ T cells, CD8+ T cells and NK cells were markedly lower in diabetic cases than in non-diabetic cases. The non-survivors showed the markedly declined counts of CD8+ T cells and NK cells than survivors. Conclusion: The elevated cytokines, imbalance of Th1/Th2 cytokines ratios and reduced of peripheral numbers of CD8+ T cells and NK cells might contribute to the pathogenic mechanisms of high mortality of COVID-19 patients with T2DM.
