This study examined health-related quality of life within the first 5 years following concurrent mild traumatic brain injury (MTBI) and polytrauma. Participants were 167 U. S. service members who had sustained a MTBI who had completed a brief neurobehavioral evaluation within 3 months postinjury and at least one telephone follow-up interview at 6 (n = 46), 12 (n = 89), 24 (n = 54), 36 (n = 42), 48 (n = 30) or 60 months (n = 25) postinjury. ⋯ A minority reported suicidal or homicidal ideation (5.6% to 14.8%). Recovery from MTBI in a military setting is complex and multifaceted. Continued support and care for all service members who sustain a combat-related MTBI with polytrauma is recommended, regardless of the presence or absence of symptom reporting within the first few months postinjury.

Blast-induced ocular trauma is a frequent cause of morbidity for survivors of improvised explosive devices. Blast overpressure (BOP) of 120 ± 7 KPa has been shown to cause damage to lungs, brain, and gut in a rat model; however, the effects of BOP on ocular tissues have not been characterized. To elucidate the pathophysiology of blast-induced ocular trauma, ocular tissues from rats subjected to blast were examined for evidence of apoptosis by the detection of activated caspase 3 and TUNEL assay in their ocular tissues. ⋯ BOP of 120 ± 7 KPa induces optic neuropathy and retinal damage. In both the optic nerve and retina, caspase 3 was activated in the right and left sides following blast exposure. The results of this study reveal that blast exposure induces apoptosis in both the optic nerve and retinal tissues.

In the tactical setting, intraosseous (IO) access has become popular to treat hemorrhagic shock when peripheral intravenous access is difficult or impractical. The traditional sites most commonly used by combat medics, corpsmen, and Pararescuemen (PJs) include the sternum and tibial tuberosity. Recent studies have shown that the humeral head (HH) is an appropriate and effective access site for IO infusion and fluid resuscitation in the clinical setting. ⋯ First pass success rates were 96% and 90.5% for the drill and driver, respectively. Both devices achieved 100% success by the second pass. Military field personnel would benefit from a HH approach, especially in the care and management of patients of explosive injuries.

Comparative Study
Attrition due to orthopedic reasons during combat training: rates, types of injuries, and comparison between infantry and noninfantry units.
The purpose of this study is to identify the prevalence and types of orthopedic injuries in infantry and noninfantry units responsible for attrition from combat training. ⋯ On the basis of our results, we recommend a multidisciplinary intense effort including physicians, physical training officers, physiotherapists, and commanders to significantly reduce overuse injuries, especially in the low-back and lower extremity regions.

U. S. Army Combat Medic serves as both Soldier and provider of combat casualty care, often in the heat of battle and with limited resources. ⋯ Those meeting a mental health screening criteria were more likely to report associated stigma and barriers to care. Findings indicate that Medics in need of assistance report greater perceived barriers to mental health care, as well as stigma from seeking treatment, and that depression may be a salient issue for Medics. The longitudinal nature of the ongoing study will help determine the actual trajectory and onset of depression and post-traumatic stress disorder.
