Longer steps with load carriage is common in shorter Soldiers when matching pace with taller Soldiers whereas shorter steps are hypothesized to reduce risk of injury with load carriage. The effects of load carriage with and without step length manipulation on loading patterns of three commonly injured structures were determined: Achilles tendon, patellofemoral joint (PFJ) and medial tibiofemoral joint (mTFJ). ⋯ A preferred step length is the safest strategy when walking with load carriage. Taking a shorter step is not an effective strategy to reduce loading on the Achilles tendon, PFJ, and mTFJ.

Exertional Heat Illness with associated ischemic hepatitis (IH) is a common occurrence among military trainees; however, few specific therapies exist if unresponsive to appropriate supportive measures. A 27-year-old basic combat trainee presented with altered mental status, renal insufficiency, rhabdomyolysis, and a core temp of 107.9 °F after collapsing during a run, leading to the diagnosis of heat stroke. While the patient's azotemia and creatinine kinase levels rapidly improved with aggressive intravenous hydration, transaminases continued to increase to nearly 155 times the upper limit of normal. ⋯ The mortality of IH among critically ill patients has been estimated to be as high as 60%, with those demonstrating coagulopathy especially at risk. NAC is shown to improve the transplant-free survival rate in non-acetaminophen related ALF, consistent with its proposed mechanisms of improving hepatic blood flow and conjugating toxic metabolites. NAC therapy should be considered early in the course of heat injury-mediated IH to reduce reperfusion injury, improving transplant free outcomes.

Rabies remains a global threat, with annually over 59,000 deaths. Intradermal (ID) pre-exposure prophylaxis (PrEP) is very efficient and reduces the need for rabies immunoglobulins. Not much is known about factors that influence the immune response to ID administered rabies vaccine. The aim of this study is to determine if variations in timing of vaccine administration and serology determination, age and gender have an influence on the levels of rabies virus neutralizing antibody (RVNA) after ID rabies vaccination. ⋯ Timing of vaccine dose administration, timing of serology testing, sex and age do significantly influence the humoral B-cell response to ID administered rabies vaccine.

The number-one service-connected disability is tinnitus. Tinnitus currently has no cure, but the functional impact of tinnitus has been shown to be mitigated by Progressive Tinnitus Management (PTM), a multi-level management approach. The duration of PTM Level 3 skills education (PTM-SE) and the inclusion of mental health providers have been identified as barriers to implementation of PTM-SE in Department of Defense (DOD) medical treatment facilities. The goal of this study was to determine if a version of PTM-SE modified for use in DOD medical treatment facilities resulted in positive changes in tinnitus-related outcomes. ⋯ The evidence supports the assumption that PTM is a flexible program of tinnitus management that even when modified to be suitable for use in a DOD medical treatment facility provides meaningful reductions in tinnitus awareness and annoyance and improves tinnitus coping ability among military beneficiaries. These findings should encourage audiologists to modify PTM to work within their military medical treatment facility.
