Randomized Controlled TrialImpact of Low-Level Blast Exposure on Brain Function after a One-Day Tactile Training and the Ameliorating Effect of a Jugular Vein Compression Neck Collar Device.
Special Weapons and Tactics (SWAT) personnel who conduct breacher exercises are at risk for blast-related head trauma. We aimed to investigate the potential impact of low-level blast exposure during breacher training on the neural functioning of working memory and auditory network connectivity. We also aimed to evaluate the effects of a jugular vein compression collar, designed to internally mitigate slosh energy absorption, preserving neural functioning and connectivity, following blast exposure. ⋯ The elevation in fMRI activation in the non-collar group was found to correlate significantly (n = 7, r = 0.943, p = 0.001) with average peak impulse amplitude experienced during the training. In the resting-state fMRI analysis, significant pre- to post-training increase in connectivity between the auditory network and two discrete regions (left middle frontal gyrus and left superior lateral occipital/angular gyri) was found in the non-collar group, while no change was observed in the collar group. These data provided initial evidence of the impact of low-level blast on working memory and auditory network connectivity as well as the protective effect of collar on brain function following blast exposure, and is congruent with previous collar findings in sport-related traumatic brain injury.

Healthcare providers and law enforcement utilize spit socks to prevent exposure to communicable diseases transmitted by bodily fluid projection from agitated individuals. There are cases in which death is reported due to breathing being limited by a spit sock. There are no formally published studies on their use and safety. The aim of this study was to evaluate whether wearing a spit sock causes a clinically significant impact on breathing. ⋯ In healthy subjects there were no clinically significant changes in the physiologic parameters of breathing while wearing a spit sock.

Human factors-based risk analysis to improve the safety of doffing enhanced personal protective equipment.
To systematically assess enhanced personal protective equipment (PPE) doffing safety risks. ⋯ Despite detailed guidelines, our study revealed 103 enhanced PPE doffing failure modes. Analysis of the failure modes suggests potential mitigation strategies to decrease self-contamination risk during enhanced PPE doffing.

Decontamination of CBRN units contaminated by highly contagious biological agents.
A decontamination process plays a key role in management of biological incidents. While decontamination of surfaces and buildings located in the hot zone can be usually postponed until an agent is confirmed and an adequate planning phase is established, personnel wearing personal protective equipment must be decontaminated prior to their final exit from the hot zone. ⋯ Experimental tests with surrogates of biological agents are thus necessary to identify above-mentioned points. Once an optimal decontamination procedure is recognized, a field rehearsal must follow and the method using a surrogate must be implemented into a training process of CBRN units.

Risk of self-contamination during doffing of personal protective equipment.
PPE doffing carries significant risk for self-contamination. Assisted doffing likely reduces this risk.
