The features of a gunshot injury arising in the presence of body armor on the injured person are considered. The purpose of the work is to reveal the mechanisms of damage formation during non-penetration of an armored composition, during its penetration, as well as during external or internal rebound. The characteristic of damages arising with this is given. ⋯ With through penetration of body armor, the severity and volume of gunshot damage increase due to the introduction of fragments of bullets, fragments of armored panels and pieces of equipment into the wound channel. Rebounding of elements of dismantled bullets from the outer or inner surface of the body armor can cause severe gunshot damage to both the wearer of body armor and other persons. Knowledge of the mechanisms of formation and morphological features of injuries that occur when using body armor are prerequisites for a full forensic medical assessment of the investigated incident.

A systematic review of the world literature data on surgical management and preoperative screening of cancer patients within the COVID-19 pandemic, as well as prevention of SARS-CoV-2 transmission and resumption of elective surgery. ⋯ To date, the COVID-19 pandemic is still not resolved, and infection continues spreading around the world. Thus, there is an urgent need for more thorough research of the strategies for mitigating the effects of pandemic. To date, the recommendations for optimal surgical management of cancer patients within the pandemic are still actively developed considering the benefits of treatment and risks of SARS-CoV-2 infection. Resumption of elective surgery should be progressive and cautious, especially in pandemic areas. For safety reasons, all patients eligible for surgical treatment should be carefully selected according to stratification of risk factors. Thorough preoperative screening, monitoring of symptoms of infection, and use of appropriate adapted personal protective equipment are extremely important.

During the current SARS-CoV-2 pandemic there is unprecedented demand for personal protective equipment (PPE), especially N95 respirators and surgical masks. The ability of SARS-CoV-2 to be transmitted via respiratory droplets from asymptomatic individuals has necessitated increased usage of both N95 respirators in the healthcare setting and masks (both surgical and homemade) in public spaces. These precautions rely on two fundamental principles of transmission prevention: particle filtration and droplet containment. ⋯ These materials demonstrate significant variability in filtration characteristics, even for visually similar materials. We demonstrate a FE of 96.49% and pressure drop of 25.4 mmH20 for a double-layer of sterilization wrap used in surgical suites and a FE of 90.37% for a combination of consumer-grade materials. The excellent filtration characteristics of the former demonstrate potential utility for emergent situations when N95 respirators are not available, while those of the latter demonstrate that a high FE can be achieved using publicly available materials.

The COVID-19 pandemic has presented an unprecedented strain on healthcare supplies. Currently there is a global shortage of personal protective equipment (PPE), especially N95 masks. In order to safeguard healthcare personnel in this critical time and to mitigate shortages of N95 respirators, reuse of N95 respirators has to be considered. ⋯ In light of the COVID-19 pandemic, reuse of N95 respirators, although suboptimal, can be considered. Evidence reveals that UVGI, MHI, and HPV are amongst the safest and efficacious methods for decontamination of N95 masks. More research is needed to establish the safety and effectiveness of MGS, MSB, dry heat, EtO, liquid hydrogen peroxide, and HPGP. Alcohol, microwave irradiation, and bleach are not recommended because they damage N95 respirators.

ReviewChest tubes in COVID-19 times: a safe way to protect the team.
What has been published so far regarding safe methods to deal with chest tube insertion during COVID-19. ⋯ Health officials are under increasing pressure to control the spread of COVID-19, which is a very virulent disease. Our analysis brought together old rules against contamination along with new tactics for professionals who deal with chest drains in order to minimize the contamination of teams during the Pandemic.
