Investigation of Psychological Stress and Sleep Quality of Emergency Medical Technicians in Taiwan Fire Department during the COVID-19 Pandemic.

When the coronavirus disease 2019 (COVID-19) began to ravage the world in 2019, the World Health Organization became concerned. The epidemic has a high mortality and contagion rate, with severe health and psychological impacts on frontline emergency medical service system practitioners. There are many hospital staff surveys, but few have covered the stress among emergency medical technicians. DASS-21, PSQI, and AUDIT questionnaires were used to evaluate the sources of psychological stress factors of firefighters in Taiwan. Multiple logistic regression was used to analyze the questionnaire content. We conducted questionnaire surveys from May 2022 to July 2022. Our sample comprised 688 participants. The odds ratios of increased depression, anxiety, and stress levels due to reduced family or peer understanding and support were 2.72 (95% CI: 1.50−4.92), p = 0.001; 2.03 (95% CI: 1.11−3.68), p = 0.021; and 3.27 (95% CI: 1.83−5.86), p < 0.001, respectively. The odds ratios of poor sleep quality due to depression, anxiety, and increased stress levels were 5.04 (3.18−7.99), p < 0.001; 2.44 (95% CI: 1.57−3.81), p < 0.001; and 4.34 (95% CI: 2.76−6.82), p-value < 0.001, respectively. During the COVID-19 pandemic, poor sleep quality and a lack of understanding and support from the Taiwan firefighting agency staff, family, or peers resulted in increased depression, anxiety, and stress levels.

Prophylaxis for covid-19: living systematic review and network meta-analysis (preprint)

Objective To determine and compare the effects of drug prophylaxis on severe acute respiratory syndrome coronavirus virus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (covid-19). Design Living systematic review and network meta-analysis. Data sources WHO covid-19 database, a comprehensive multilingual source of global covid-19 literature to 19 January 2021, and six additional Chinese databases to 20 January 2021. Study selection Randomized trials in which people at risk of covid-19 were randomized to drug prophylaxis or no prophylaxis (standard care or placebo). Pairs of reviewers independently screened potentially eligible articles. Methods After duplicate data abstraction, we conducted random-effects bayesian network meta-analysis. We assessed risk of bias of the included studies using a modification of the Cochrane risk of bias 2.0 tool and assessed the certainty of the evidence using the grading of recommendations assessment, development and evaluation (GRADE) approach. Results The first iteration of this living network meta-analysis includes nine randomized trials: six addressing hydroxychloroquine (6,059 participants), one addressing ivermectin combined with iota-carrageenan (234 participants) and two addressing ivermectin alone (540 participants), all compared to standard care or placebo. Hydroxychloroquine has no important effect on admission to hospital (risk difference (RD) 1 fewer per 1,000, 95% credible interval (CrI) 3 fewer to 4 more, high certainty) or mortality (RD 1 fewer per 1,000, 95% CrI 2 fewer to 3 more, high certainty). Hydroxychloroquine probably has no important effect on laboratory-confirmed infection (RD 2 more per 1,000, 95% CrI 18 fewer to 28 more, moderate certainty), probably increases adverse effects leading to drug discontinuation (RD 19 more per 1,000, 95% CrI 1 fewer to 70 more, moderate certainty) and may have no important effect on suspected, probable or laboratory-confirmed infection (RD 15 fewer per 1,000, 95% CrI 64 fewer to 41 more, low certainty). Due to serious risk of bias and very serious imprecision, and thus very low certainty evidence, the effects of ivermectin combined with iota-carrageenan on laboratory-confirmed infection (RD 52 fewer per 1,000, 95% CrI 58 fewer to 37 fewer), and ivermectin alone on laboratory-confirmed infection (RD 50 fewer per 1,000, 95% CrI 59 fewer to 16 fewer) and suspected, probable or laboratory-confirmed infection (RD 159 fewer per 1,000, 95% CrI 165 fewer to 144 fewer) remain uncertain. Conclusion Hydroxychloroquine prophylaxis does not have an important effect on hospital admission and mortality, probably increases adverse effects, and probably does not have an important effect on laboratory-confirmed SARS-CoV-2 infection. Because of serious risk of bias and very serious imprecision, we are highly uncertain whether ivermectin combined with iota-carrageenan and ivermectin alone reduce the risk of SARS-CoV-2 infection.
