Background: Healthcare workers (HCWs) employed personal protective equipment (PPE) during the COVID-19 pandemic, crucial to protecting themselves from infection. To highlight the efficacy of PPE in preventing environmental infection among HCWs, a systematic review was conducted in line with PRISMA guidance.Methods: A search of the PubMed and Web of Science databases was conducted from January 2019 to April 2021 using pre-defined search terms. Articles were screened by three researchers. The approved papers were read in full and included in this review if relevance was mutually agreed upon. Data were extracted by study design and types of PPEs.Results: 47 of 108 identified studies met the inclusion criteria, with seven reviews and meta-analyses, seven cohort, nine case-control, fifteen cross-sectional studies, four before and after, four case series, and one modeling studies. Wearing PPE offered COVID-19 protection in HCWs but required adequate training. Wearing surgical masks provided improved protection over cloth masks, while the benefit of powered air-purifying respirators is less clear, as are individual gowns, gloves, and/or face shields.Conclusions: Wearing PPE, especially facial masks, is necessary among HCWs, while training in proper use of PPE is also important to prevent COVID-19 infection.

The predictors of pacing capture threshold (PCT) exacerbation after leadless pacemaker implantation remain unknown. We analyzed the predictors of poor PCT by identifying risk factors using multivariate logistic regression analysis for 211 patients with leadless pacemaker implantation. Twenty patients met the criteria for elevated PCT levels and were categorized in the poor PCT group. Multivariate analyses revealed that PCT (P < 0.0001) and pacing impedance (P = 0.03) were independent predictors of PCT exacerbation. Elevated PCT levels and low pacing impedance during leadless pacemaker implantation were potential risk factors for the replacement of leadless pacemakers after the procedure.
