Background: The pandemic of coronavirus disease (Covid-19) seriously impacts the health and well-being of all of us. Aims: We aim to assess the psychological impact of Covid-19 on frontline health care workers (HCWs), including anxiety, depression and stress of threat of the disease. Method: The study was a cross-sectional survey among the frontline HCWs in a hospital at Jinan, China. Data were collected through an anonymous, self-rated questionnaire, including basic demographic data, a 10-item Covid-19 stress questionnaire, the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS). The risk and rate of anxiety, depression and stress of Covid-19 were estimated. Results: Among the 309 participants, there were 88 (28.5%) with anxiety and 172 (56.0%) with depression. Multivariate logistic regression analyses showed that age ⩽ 30 years, age > 30 to 45 years, working in confirmed case isolation wards, and worrying about disinfection measures being not sufficient were independently associated with anxiety with an odds ratio (95% confidence interval, CI) of 4.4 (1.6–12.2), 3.1 (1.1–8.8), 2.3 (1.4–4.0) and 2.5 (1.5–4.3), respectively; age ⩽ 30 years, age > 30 to 45 years, nurse and worrying about disinfection measure being not sufficient were independently associated with depression with an odds ratio (95% CI) of 3.8 (1.8–7.8), 2.7 (1.3–5.7), 2.5 (1.1–5.6) and 2.1 (1.3–3.5), respectively. Conclusions: A high prevalence of anxiety and depression was found among frontline HCWs during the COVID-19 outbreak. More psychological care should be given to young staffs and nurses. Measures to prevent professional exposure is important for HCWs' physical and mental health. [ABSTRACT FROM AUTHOR]

The objective of this study was to investigate the impact of trauma exposure on the posttraumatic stress symptomatology (PTSS) of children who resided near the epicenter of the 2008 Wenchuan earthquake. The mechanisms of this impact were explored via structural equation models with self-esteem and coping strategies included as mediators. The findings suggested that the effect of trauma exposure was partially mediated by self-esteem, which subsequently affected coping strategies and finally determined PTSS. These results imply that self-esteem and coping strategies may impact children's resilience to trauma exposure. [ABSTRACT FROM AUTHOR]

Context.--Cardiac troponins have become the gold standard for diagnosing acute myocardial infarction (AMI) in the general population; however, their diagnostic accuracy for hemodialysis (HD) patients presenting with chest pain or dyspnea is uncertain. Objective.--To examine the diagnostic accuracy of high-sensitivity cardiac troponin T (hs-cTnT) assay for AMI in HD patients. Design.--In this prospective study, we enrolled 670 consecutive stable HD patients presenting with chest pain or dyspnea on routine predialysis therapy in the nephrology department. Receiver operating characteristic (ROC) curves were used to examine the diagnostic accuracy of hs-cTnT levels at enrollment in HD patients presenting with chest pain or dyspnea, and the dynamic change in these levels after 3 hours. Results.--Acute myocardial infarction was the adjudicated final diagnosis in 12% of HD patients. Among patients with a final diagnosis other than AMI, 97% had a plasma hs-cTnT concentration above the 99th percentile. At the time of enrollment, the area under the ROC curve of hs-cTnT levels for diagnosis of AMI was 0.68 (95% confidence interval [CI], 0.62-0.74; P < .001) with a cutoff value of 107.7 ng/L; the relative change after 3 hours was 0.90 (95% CI, 0.82-0.96, P < .001) with a cutoff value of 24%, and the absolute change was 0.88 (95% CI, 0.82-0.94, P < .001) with a cutoff value of 32.6 ng/L. The prognostic value for 40-day mortality varied with the magnitude of elevation in hs-cTnT levels. Conclusions.--Tracking the dynamic change in hs-cTnT levels during the short term significantly increased this measure's diagnostic accuracy for AMI in HD patients. [ABSTRACT FROM AUTHOR]
