Veterans are at risk for mental and physical health problems but may not seek traditional health care services. Wellness-based interventions, including exercise and nutrition, have been associated with improvements in physical and mental health among this population. This study explores the acceptability, feasibility, and efficacy of a 3-month health and fitness program for veterans. ⋯ These data suggest that a 3-month health and fitness program for veterans is acceptable and feasible and may improve physical and mental health outcomes. Considerations for program retention and assessment completion are discussed.

Warfighters are exposed to life-threatening injuries daily and according to the Joint Trauma System Military Clinical Practice Guideline-Global Snake Envenomation Management snakebites are a concerning threat in all theaters of operation. Snake venom is a complex mixture of toxins including phospholipases A2 (PLA2) and snake venom metalloproteinases (SVMP) that produce myotoxic, hemotoxic, and cytotoxic injuries. Antibody-based antivenom is the standard of care but new approaches including small-molecule inhibitors have gained attention in recent years. Doxycycline is an effective inhibitor of human metalloproteinases and PLA2. The enzymatic activities of 3 phylogenetically distinct snakes: Agkistrodon piscivorus, Naja kaouthia, and Daboia russelii were tested under inhibitory conditions using doxycycline. ⋯ Doxycycline reduced PLA2- and SVMP-related lethality, particularly in A. piscivorus envenomings and in a limited capacity with D. russelii revealing its promise as a treatment for snakebites. In addition, CK activity, a common indicator of muscle damage was inhibited in mice that received doxycycline-treated venom. The doxycycline concentrations identified in the ED50 studies correspond to 1,456 to 5,061 mg dosages for a 70 kg human. Factors including venom yield and snake species would affect the actual dosage needed. Studies into high-dose doxycycline safety and its effectiveness against several snake species is needed to fully translate its use into humans. Based on this work, doxycycline could be used as a treatment en route to higher echelons of care, providing protection from muscle damage and reducing lethality in different snake species.

This study reports rates of comorbid chronic pain and post-traumatic stress disorder (PTSD) among U.S. military veterans and rates of psychiatric comorbidities among those with both chronic pain and PTSD. ⋯ Patients with comorbid chronic pain and PTSD may benefit from tailored treatments to address the additive impact of these conditions.

In prolonged care scenarios, where medical evacuations are significantly delayed, the treatment and transport of casualties with extremity musculoskeletal injuries will drain combat units' human resources. Developing enhanced splinting techniques to restore casualty mobility and function can alleviate this drain. To guide this development, a panel of tactical combat and wilderness medicine experts was assembled to determine which extremity musculoskeletal injuries had the greatest impact on unit capabilities, and the materials available for splinting these injuries. ⋯ Although the combined impact of knee and ankle ligamentous injuries were ranked the highest, limitations in relative rankings and the existence of effective low-cost treatments for these injuries suggest that greater gains in unit effectiveness would come from focusing on developing solutions for fractures with higher human resource cost, such as leg and arm fractures. This information can be used to develop enhanced splints that can preserve unit readiness in the field.

The purpose of the study was to determine whether performing ultrasound-guided, bilateral stellate ganglion blocks (SGBs; performed on subsequent days) improved traumatic brain injury (TBI) symptoms. ⋯ The use of bilateral, 2-level SGBs may be indicated in treating patients with PTSD symptoms with concomitant diagnoses of mild-to-moderate TBI.
