This study presents a new approach to developing protective material structures for personal protective equipment (PPE), and in particular for protective gloves, with the use of ultrasonic and contact welding processes. The goal was to assess the quality of joints (welds) obtained between a synthetic polyamide knitted fabric (PA) and selected polymers (PLA, ABS, PET-G) in the developed materials using X-Ray microtomography (micro-CT). Quantitative and qualitative analyses were performed to determine the joint area produced by the selected welding methods for the examined materials. In this article, we assumed that obtaining a greater contact area seems to be the most promising from the point of view of future PPE utility tests characterizing protective glove structures. This research is a continuation of our previous study focused on functional 3D-printed polymeric materials for protective gloves.

Objective: to analyze the association between participation in training activities and the adherence to and use of personal protective equipment by workers and professionals involved in Health Residency Programs in Primary Health Care during the COVID-19 pandemic.
Methods: a cross-sectional study in Brazil between August/2020 and March/2021. We utilized the EPI-APS COVID-19 instrument and its adapted version for resident professionals.

Introduction: The COVID-19 pandemic has created an urgent demand for research, which has spurred the development of enhanced biosafety protocols in biosafety level (BSL)-3 laboratories to safeguard against the risks associated with handling highly contagious pathogens. Laboratory management failures can pose significant hazards.
Methods: An external system captured images of personnel entering a laboratory, which were then analyzed by an AI-based system to verify their compliance with personal protective equipment (PPE) regulations, thereby introducing an additional layer of protection.

Background: Personal protective equipment (PPE) doffing protocols can reduce risks of pathogen self-contamination. Powered air purifying respirators (PAPRs) may increase these risks. This study compares viral contamination and errors during simulated doffing of single layer vs double layer hood PAPRs.

Intramedullary nail fixation is a routine procedure for treatment of intertrochanteric fractures. Aseptic technique is vital for reducing postoperative complications, as intraoperative glove perforations increase the risk of surgical site infections. The aim of this study was to determine the incidence of surgical glove perforation during intramedullary nailing of intertrochanteric fractures and to identify surgery-specific steps at risk.

Firefighters are exposed to a variety of hazardous substances during firefighting activities. Fire smoke contains polycyclic aromatic hydrocarbons (PAHs) some of which have been shown to cause cancer in humans. To assess dermal exposure of firefighters during real-life firefighting, a whole-body dosimetry method was applied to determine the PAH that settles on the skin despite firefighters wearing personal protective equipment (PPE).
