Randomized Controlled TrialComparing Training Techniques in Personal Protective Equipment Use.
Physicians' management of hazardous material (HAZMAT) incidents requires personal protective equipment (PPE) utilization to ensure the safety of victims, facilities, and providers; therefore, providing effective and accessible training in its use is crucial. While an emphasis has been placed on the importance of PPE, there is debate about the most effective training methods. Circumstances may not allow for a traditional in-person demonstration; an accessible video training may provide a useful alternative. ⋯ In this pilot study, video and in-person training were equally effective in training for donning and doffing Level C PPE, with similar error rates in both modalities. Further research into this subject with an appropriately powered study is warranted to determine whether this equivalence persists using a larger sample size.

ReviewAn Insight into the Sex Differences in COVID-19 Patients: What are the Possible Causes?
Studies have reported a sex bias in case fatalities of COVID-19 patients. Moreover, it is observed that men have a higher risk of developing a severe form of the disease compared to women, highlighting the importance of disaggregated data of male and female COVID-19 patients. On the other hand, other factors (eg, hormonal levels and immune functions) also need to be addressed due to the effects of sex differences on the outcomes of COVID-19 patients. ⋯ The current study reviews the reports concerning with the sex differences in COVID-19 patients. It is explained how sex can affect angiotensin converting enzyme-2 (ACE2), that is a key component for the pathogenesis of COVID-19, and summarized the gender differences in immune responses and how sex hormones are involved in immune processes. Furthermore, the available data about the impact of sex hormones on the immune functions of COVID-19 cases are looked into.

Remaining Cervical Spine Movement Under Different Immobilization Techniques.
Immobilization of the cervical spine by Emergency Medical Services (EMS) personnel is a standard procedure. In most EMS, multiple immobilization tools are available.The aim of this study is the analysis of residual spine motion under different types of cervical spine immobilization. ⋯ The remaining movement of the cervical spine is minimal when the patient is immobilized on a spine board with a headlock system and a Spider Strap harness system or on a vacuum mattress with additional headblocks. The remaining movement of the cervical spine could not be reduced by the additional use of a cervical collar.

Critical Care Surge Capacity to Respond to the COVID-19 Pandemic in Italy: A Rapid and Affordable Solution in the Novara Hospital.
The rapid insurgence and spread of coronavirus disease 2019 (COVID-19) exceeded the limit of the intensive care unit (ICU) contingency plan of the Maggiore della Carità University Hospital (Novara, Italy) generating a crisis management condition. This brief report describes how a prompt response to the sudden request of invasive mechanical ventilation (IMV) was provided by addressing the key elements of health care system surge capacity from contingency to crisis. In a short time and at a relatively low cost, a structural modification of a hospital aisle allowed to convert the general ICU into a COVID-19 unit, increasing the number of COVID-19 critical care beds by 107%.

Observational StudyEffect of Road Safety Laws on Deaths and Injuries from Road Traffic Collisions in Colombia.
Colombia is the fourth largest country in South America. It is an upper middle-income country with an estimated population of 49.2 million people, and road traffic collisions (RTCs) are the second most common cause of traumatic death. The United Nations (UN) proclaimed 2011 to 2020 as the "Decade of Action for Road Safety." In this context, the government of Colombia established the National Road Safety Plan (PNSV) for the period 2011-2021, aiming to reduce RTC-related deaths by 26%. Some road safety laws (RSLs) were implemented before the PNSV, but their impact on deaths and injuries is still not known. ⋯ Despite the introduction of the PNSV, RTCs remain the second most common cause of preventable death in Colombia. Overall, while the absolute number of RTCs and deaths has been increasing, the rate of RTCs per 10,000 registered vehicles has been decreasing. This suggests that although the goals of the PNSV may not be realized, some of the laws emanating from it may be having a beneficial effect. Further study is required over a protracted period to determine the longer-term impact of these initiatives.
