Background: During the coronavirus disease 2019 pandemic, wearing medical respirators and masks was essential to prevent transmission.
Objective: To quantify the effects of N95 mask usage by measuring facial skin biophysical characteristics and changes in the lipidome.
Methods: Sixty healthy volunteers wore N95 respirators for 3 or 6 h. Facial images were acquired and physiological parameters were measured in specific facial areas, before and after mask-wearing. Lipidome analysis was also performed.
Results: After N95 respirator usage, facial erythema was observed in both the 3 and 6 h groups. Both sebum secretion and trans-epidermal water loss increased significantly in mask-covered cheeks and chins after 6 h of mask wearing compared with before mask wearing (p < 0.05). Principal component analysis revealed significant differences in lipid composition after mask wearing compared with before. The ceramide subclass NS exhibited a positive correlation with stratum corneum hydration, whereas the AP subclass was negatively correlated with trans-epidermal water loss in the 6 h group.
Conclusion: Prolonged wear of N95 respirators may impair facial skin function and alter lipidome composition.

Preliminary study on the ejection of microplastics from different types of face masks.

Face masks are strongly believed to be the best precaution to reduce the transmission of the SARS-CoV-2 virus, which resulted in an unprecedented surge in the production and use of personal respiratory protective equipment. Unfortunately, this surge led to improper disposal of used masks. This study aimed to assess the occurrence of microplastics (MPs) in used and unused surgical and cloth masks and N95 respirators.

Experiencing side effects when wearing N95/P2 masks has negative impacts on health workers and increases exposure to pathogens. While side effects of wearing P2/N95 masks have been reported previously, these masks have never been used as widely as during the COVID-19 pandemic. This study examines Australian hospital nurses' experiences and perceptions of P2/N95 mask usage and its impacts on patient care at a time when P2/N95 masks were widely used.

Developing and overseeing Respiratory Protection Programs (RPPs) is crucial for ensuring effective respirator use among employees. To date, a gap exists in research that focuses on elastomeric half mask respirators (EHMRs) as the primary respirator in health delivery settings which would necessitate additional considerations in RPPs beyond the more common N95 filtering facepiece respirators. This paper presents lessons learned during a one-year impact evaluation with healthcare and first responder settings that received EHMRs from the Strategic National Stockpile in 2021 and 2022.

Background: Quantitative mask fit testing (QNFT) is the gold standard to confirm the correct fit of a N95/P2 mask to ensure health care workers protection from airborne viruses. Using the Occupational Safety and Health Administration (OSHA) guidance indicates a final fit test result is a cumulative score derived from manoeuvres within the OSHA protocol. The protocol-based manoeuvres mimic aspects of clinical care by health professionals and mask fit testing is conducted to provide protection from airborne viruses and pollutants within a care setting.
