The 1996 Khobar Towers bombing, a large-scale mass casualty incident (MASCAL) at a coalition forces housing complex, resulted in 519 casualties. Key lessons learned include the importance of MASCAL exercises, self-aid and buddy care, and casualty triage, all critical to preparation for future terrorist attacks or near-peer combat operations MASCALs.

This work explores the challenges of delivering medical care in the geographically dispersed and resource-constrained environment of Distributed Maritime Operations (DMO) and Expeditionary Advanced Base Operations (EABO). Traditional medical planning approaches may struggle to adapt to the vast operational space, extended evacuation times, and limited medical force present in these scenarios. The concept of a Medical Common Operating Picture (COP) emerges as a potential solution. ⋯ Implementing such a medical COP system will require overcoming communication limitations to facilitate data exchange and potentially integrating clinical decision support tools for real-time data analysis and recommendations. It will also require the rapid adoption of modernized operational medicine documentation solutions by medical assets within the operational forces. Ultimately, this work suggests that a medical COP has the potential to bridge the gap between traditional medical planning and the unique demands of DMO/EABO, ultimately optimizing casualty care, maximizing resource efficiency, and preserving the fighting force.

Assessing the survivability of, and potential injury to, a ship's crew from underwater blast is crucial to understanding the operating capability of a military vessel following blast exposure. One form of injury that can occur and affect a crew member's ability to perform tasks is traumatic brain injury (TBI). To evaluate the risk of TBI from underwater blasts, injury metrics based on linear head acceleration have traditionally been used. Although these metrics are popular given their ease of use, they do not provide a direct measure of the tissue-level biomechanical responses that have been shown to cause neuronal injury. Tissue-based metrics of injury, on the other hand, may provide more insight into the potential risk of brain injury. Therefore, in this study, we assess the risk of TBI from underwater blasts using tissue-based measures of injury, such as tissue strain, strain rate, and intracranial pressure, in addition to the more commonly used head acceleration-based injury metrics. ⋯ In this work, we assessed the risk of brain injury from underwater blasts using an anatomically detailed subject-specific FE head model. Accurate assessment of the risk of TBI from underwater explosions is important to evaluate the potential injury risk to crew members from underwater blast events, and to guide the development of future injury mitigation strategies to maintain the safety of crew members on military ships.

Vasectomy is a relatively common procedure performed for the purposes of sterilization; however, up to 6% of men that undergo vasectomy wish for its reversal at some point. Few studies have examined the motivation behind vasectomy reversal (VR), especially within special populations, such as the U.S. Military. The aim of this study was to examine the motivations of U.S. Military service members (SMs) who opted for VR surgery, considering their unique access to free health care. ⋯ Our study demonstrates that the primary driver for seeking VR surgical care among SMs was the desire for fertility with a new partner, which correlates with trends in the civilian sector. Approximately 20% of the men cited the wish to have more children with the same partner as their motivation. Non-fertility reasons, such as religious beliefs and post vasectomy pain syndrome, were also observed, albeit less frequently.

Uncontrolled torso hemorrhage is the primary cause of potentially survivable deaths on the battlefield. Zone 1 Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), in conjunction with damage control resuscitation, may be an effective management strategy for these patients in the prehospital or austere phase of their care. However, the effect of whole blood (WB) transfusion during REBOA on post-occlusion circulatory collapse is not fully understood. ⋯ WB transfusion during Zone 1 REBOA was not associated with increased short-term survival in this large animal model of severe hemorrhage. We observed no signal that WB transfusion may mitigate post-occlusion circulatory collapse. However, there was evidence of supra-normal blood pressures during WB transfusion.
