A variety of factors influence the motivation to choose a medical career; however, the influence of premedical experiences on health professional trainees' choices is a neglected one. We hypothesize that medical exposure during service in the Israeli Air Force special operations forces (SOFs) has an impact on motivation for medical studies. The Israeli scenario, in which career choice is anteceded by substantial military experience, allows us to examine this hypothesis. ⋯ Medical exposure of Unit 669 operators during military service significantly contributed to their motivation for becoming physicians. Thus, military service in this setting acts de facto as an effective medical immersion program. This adds another factor to the myriad of factors that motivate young adults in their choice of a medical career.

Traumatic brain injuries are of concern to the sports and military communities because of the age of the participants and costly burden to society. To markedly reduce the impact of traumatic brain injury and its sequela (TBI-S), it is necessary to determine the initial vulnerability of individuals as well as identify new technologies that indicate early signs of TBI-S. ⋯ The studies and results are consistent with prior work demonstrating that noninvasive tests may be sensitive to the presence of TBI-S, potentially in the training field as advances in the portability of test instruments are underway. When combined with baseline data gathered from individuals in quantitative form, key variances can emerge. Therefore, it is hypothesized that AEP, OKN, and OCT, taken together, may yield faster objective and quantitative neurophysiological measures serving as a "signature" of neural injury and more indicative of potentially persistent TBI-S-recommending larger scale longitudinal studies.

The objective of this study was to assess the current experience of Israel Defense Forces' (IDF) advanced life support (ALS) providers in performing life-saving interventions (LSIs), the rate of doctors and paramedics achieving the Trauma and Combat Medicine Branch benchmarks, and the rate of providers feeling confident in performing the interventions although not achieving the benchmarks. ⋯ IDF ALS providers have alarmingly limited experience in performing LSIs. Many of them are confident in their ability despite not achieving evidence-based benchmarks. Additional training is required, maybe as a part of an annual medical fitness test.

This effort, motivated and guided by prior simulated injury results of the unprotected head, is to assess and compare helmet pad configurations on the head for the effective mitigation of blast pressure transmission in the brain in multiple blast exposure environments. ⋯ Optimizing helmet pad size and/or placement could provide an improved protection by minimizing the side blast orientation effects and mitigating high-pressure fields in the brain from repeated blast exposures.

Injury mechanics of blunt impact projectiles differ from those experienced in whole body motor vehicle collisions because the effects are localized around the point of impact, and thus, injury thresholds based upon gross chest kinematics (e.g., force, velocity) may not be applicable across impact types. Therefore, knowledge of biomechanically based tissue injury correlates for blunt impact projectiles are needed to better guide design and development of protective systems as well as assess injury risks from blunt impact projectile weapons. ⋯ Normalized strain-energy density was found to be the best correlate for prediction of lung tissue damage and correlate well to extent of contused lung volume.
