Successful tourniquet application increases survival rate of exsanguinating extremity hemorrhage victims. Tactile feedback during tourniquet application training should reflect human tissue properties in order to increase success in the field. This study aims to understand the mechanical properties of a human limb during tourniquet application. ⋯ Simulation of tissue compression during tourniquet application may be achieved with a material exhibiting elastic properties to mimic the force-displacement behavior seen in cadaveric tissue or with different layers of material. Different trainers for underweight, healthy, and overweight limbs may not be needed. Separate tourniquet training fixtures should be created for the upper and lower extremities.

Current methods for transporting military troops include nonstandard seating orientations, which may result in novel injuries because of different types/directions of loading impact. The objective of this study is to develop pelvic injury risk curves (IRCs) under lateral impacts from human cadaver tests using survival analysis for application to military populations. ⋯ The IRCs developed in this study can be used as injury criteria for the crashworthiness of future generation military vehicles. The introduction of BMI, sex, and total body mass as covariates quantified their contributions. These IRCs can be used with finite element models to assess and predict injury in impact environments to advance Soldier safety. Manikins specific to relevant military anthropometry may be designed and/or evaluated with the present IRCs to assess and mitigate musculoskeletal injuries associated with this posture and impact direction.

The U.S. Navy Medicine has a long history of conducting global health missions that foster international diplomacy through medical knowledge exchange with a goal of increasing partner nation's health care capacity. Pacific Partnership is an annual U.S. Navy-sponsored joint operation that enhances medical collaboration with participating nations throughout the Indo-Asia-Pacific region. Since 2015, a U.S. Navy Cardiology team has conducted a structural heart disease interventional workshop focused on congenital heart disease with the cardiologists at the Da Nang General Hospital, Da Nang, Vietnam. Herein, we describe the multinational collaborative project including the patient registry we developed to monitor the short- and long-term outcomes of structural heart disease interventions preformed during Pacific Partnership 2015 and 2016. ⋯ The development of a patient registry during these missions allowed for the longitudinal monitoring of outcomes for cardiac interventions. Notably, treated patients experienced symptomatic improvement without significant long-term procedural complications. Following patients longitudinally across medical missions is of recognized importance but remains a difficult objective to achieve for a multitude of factors including administrative and financial burdens on both the medical systems and the patients of host nations. Despite these limitations, longitudinal follow-up of patient care facilitated by a patient registry has a vital role in monitoring the quality of care provided and should be an integral part of all future global medical missions.

Vancomycin-resistant enterococci (VRE) are classified by the Centers for Diseases Control and Prevention as a serious antibiotic resistance threat. Our study aims to characterize the epidemiology, associated conditions, and outcomes of VRE infections among hospitalized patients in the U.S. military health system (MHS). ⋯ VRE infections carry a considerable burden for hospitalized patients given their impact on length of stay, hospitalization costs, and in-hospital mortality. Active surveillance and infection control efforts should target those identified as high-risk for VRE infection. Antimicrobial stewardship programs should focus on limiting exposure to 4th generation cephalosporins.

An anonymous online survey was presented to active duty U.S. Army, Reserve, and National Guard Soldiers with experience as en route care medical providers with the intent of identifying factors which contribute to musculoskeletal disorders in U.S. Army en route care medical providers. The survey looked at transport vehicle design, equipment, and awkward postures that could play a role in causing injuries. ⋯ Results of this survey emphasize the need for injury mitigation and prevention strategies to reduce impacts on soldier health and readiness.
