Medical Reserve Corps Volunteers' Characteristics Affect Disaster Survival.

OBJECTIVE: Medical Reserve Corps' volunteers underwent stop-the-bleed, triage, and disaster preparedness training to improve victim survival of a mass casualty event. METHODS: Volunteer responses to 16 disaster vignettes were recorded as 'survived' if correct, or 'died' if incorrect. Volunteers' characteristics were evaluated based on the health outcomes of the vignette victims via logistic regression. RESULTS: Overall, 69 volunteers evaluated 1104 vignette victims. STB training significantly improved survival from 77.2% to 93.2% (P < 0.001). The training did not improve disaster preparedness (75.5% to 73%) nor triage (33.5% to 35.1%). Volunteer first care provider training in psychological first aid improved victim survival from 10.32 (9.6 - 10.9, 95% CI) to 11.9 (11.28 - 12.5, 95% CI). The odds of survival increased when disaster victims received first care from a volunteer who had a positive perception of the public authority's truthfulness (1.50, range 1.07 - 2.10); stated a willingness to volunteer (1.65, range 1.2 - 2.26); completed psychological first aid training (1.557, range 1.08 - 2.22); or had 4-or-more years of post-secondary education (1.30, range 1.00 - 1.701). CONCLUSION: Psychological first aid training should be a basic requirement for disaster volunteers. Trust in public authority to provide protective public health recommendations increases disaster survival.

Pandemic Isolation and Mental Health Among Children.

OBJECTIVE: Mental health issues increased during the COVID - 19 pandemic, especially among children. Our past research efforts found that surveillance data can address a variety of health concerns; that personal psychological awareness impacted ability to cope, and mental health outcomes were improved when survivors were triaged to mental health countermeasures. To build upon our public health efforts, we wanted to see if increased screen time due to remote learning caused by the pandemic influenced school aged children's mental health. METHODS: With the hypothesis that excessive time spent isolated during remote learning increased the amount of mental health events in children, we conducted a public health surveillance project on actual diagnoses rather than just symptoms, controlling for historical mental health and emotional disorders. RESULTS: The entire cohort of children aged 6 to 17 years were studied over time before and during the pandemic for their medically diagnosed mental health and emotional outcomes by the amount of pandemic induced social isolation. CONCLUSIONS: After controlling for historical diagnoses and the rate of COVID - 19, the effect of pandemic - induced social isolation had a linear increase on the amount of anxiety, resulting in a 4-fold increase in pandemic social isolation - induced anxiety.

Prior housing conditions and sleep loss may affect recovery from brain injury in rats: a pilot study.

The purpose of this study is to understand the effect of combat-associated conditions such as sleep deprivation (SD) on subsequent traumatic brain injury (TBI). Prior to TBI (or sham surgery) induced by controlled cortical impact (CCI), rats were housed singly in chambers that prevented rapid eye movement sleep or allowed unrestricted sleep (no SD). Sensorimotor function was tested pre-SD and retested on postoperative days (PDs) 4, 7, and 14. Two additional control groups were housed socially prior to either CCI or sham surgery. CCI resulted in immediate performance deficits on sensorimotor tasks. The PD on which performance returned to baseline depended on preinjury conditions. Overall, preinjury SD+CCI resulted in an earlier recovery than no SD+CCI, and the no SD+CCI group (housed singly under conditions comparable with the SD group) recovered slower than all other groups. These data are the first to raise the possibility that recovery of sensorimotor function following TBI is affected by preinjury conditions. The data suggest that preinjury SD 24 h in duration may result in faster recovery and that novel or social isolation conditions may impede recovery. Thus, the combat environment may contribute to complexities associated with TBIs common in U.S. servicemembers.
