Review Meta AnalysisPersonal protective equipment for preventing asbestos exposure in workers.
Asbestos exposure can lead to asbestos-related diseases. The European Union (EU) has adopted regulations for workplaces where asbestos is present. The EU occupational exposure limit (OEL) for asbestos is 0.1 fibres per cubic centimetre of air (f/cm3) as an eight-hour average. Different types of personal protective equipment (PPE) are available to provide protection and minimise exposure; however, their effectiveness is unclear. ⋯ Where the outside asbestos concentration is below 0.1 f/cm3, SARS and PAPRs likely reduce exposure to below the proposed OEL of 0.01 f/cm3. For outside concentrations up to 10 f/cm3, all respirators may reduce exposure below the current OEL, but only SAR also below the proposed OEL. In band 5 (10 to < 100 f/cm3), full-face filtering masks may not reduce asbestos exposure below either OEL, SARs likely reduce exposure below both OELs, and there were no data for PAPRs. In band 6 (100 f/cm3 to < 1000 f/cm3), PAPRs may not reduce exposure below either OEL, and there were no data for full-face filtering masks or SARs. Some coveralls may increase body temperature more than others. Randomised studies are needed to directly compare PAPRs and SARs at higher asbestos concentrations and to assess adverse effects. Future studies should assess the effects of doffing procedures.

Meta Analysis
Intraosseous versus intravenous access while wearing personal protective equipment: a meta-analysis in the era of COVID-19.
Obtaining vascular access is one of the key procedures performed in patients in emergency settings. ⋯ This comprehensive meta‑analysis suggested that the use of PPE significantly extends the duration of intravascular procedures. However, under PPE conditions, operators were able to obtain intraosseous access in a shorter time and with a higher success rate than in the case of intravenous access.

Review Meta Analysis
Impact of personal protective equipment on the effectiveness of chest compression - A systematic review and meta-analysis.
To assess the impact of personal protective equipment (PPE) on different aspects of chest compression (CC) during cardiopulmonary resuscitation, we conducted this study. ⋯ The use of PPE compromises the quality of CC during CPR significantly, and newer ways to deliver chest compression has to be investigated. This study was prospectively registered in PROSPERO (CRD42020192031).

Meta AnalysisPersonal protective equipment for preventing highly infectious diseases due to exposure to contaminated body fluids in healthcare staff.
This is the second update to Verbeek et al.'s 2016 Cochrane Review of personal protective equipment (PPE) for preventing infections in healthcare workers (HCW). The prior update was in July 2019.
What's worth knowing?
Overall most studies of PPE efficacy are of low quality and offer a low certainty of conclusions. Caveat emptor...
- Powered air-purifying respirator (PAPR) with coverall may be more protective than N95 masks and gown (RR 0.27), but create unique donning challenges.
- Long-gowns may be better than a coverall, but are also more difficult to doff. Gowns are better than aprons. Better sealing, fitting, and one-piece removal at gown-glove interfaces and closer fit around the neck may reduce exposure.
- Double-gloving may reduce exposure.
- Better training, computer simulation, video lectures, following CDC protocols, and spoken instruction may improve donning and doffing compliance.
