During training and deployment, service members (SMs) experience blast exposure, which may potentially negatively impact brain health in the short and long term. This article explores if blast exposure mitigation can be effectively achieved for four different weapon training scenarios that are being monitored as part of the CONQUER (COmbat and traiNing QUeryable Exposure/event Repository) program. The training scenarios considered here are a detonating cord linear (det linear) breaching charge, a water breaching charge, a shoulder-fired weapon, and a 120-mm mortar. ⋯ Results show that the modification of the SMs' position effectively mitigated blast exposures for all considered weapon scenarios. There was at least a 50% overpressure reduction from the initial to modified standoff distances and a 35% reduction from the change in SM body posture. Based on these observations, new locations and body positioning of SMs during training have been suggested for blast mitigation.

Mild traumatic brain injury (mTBI), depression, and PTSD are highly prevalent in post-9/11 veterans. With the comorbidity of depression and PTSD in post-9/11 veterans with mTBI histories and their role in exacerbating cognitive and emotional dysfunction, interventions addressing cognitive and psychiatric functioning are critical. Compensatory Cognitive Training (CCT) is associated with improvements in prospective memory, attention, and executive functioning and has also yielded small-to-medium treatment effects on PTSD and depressive symptom severity. We sought to examine neuropsychological correlates of PTSD and depressive symptom improvement in veterans with a history of mTBI who received CCT. ⋯ Worse baseline performances on tests of processing speed and aspects of executive functioning were significantly associated with improvements in PTSD and depressive symptoms during the trial. Our results suggest that cognitive training may bolster skills that are helpful for PTSD and depressive symptom reduction and that those with worse baseline functioning may benefit more from treatment because they have more room to improve.

Combat ground maneuvers consist of various platforms and have several environmental characteristics, influenced by the terrain, the operational mission, and the force's capabilities. This study assesses data on injuries sustained during urban warfare, aiming to evaluate the relationship between injury characteristics, maneuver platform, and personal protective gear on the battlefield. ⋯ The Injury Severity Score was not influenced by environmental protection. Although we found differences in the injured body parts, further studies on the exact mechanism of injury are needed to elucidate further the relationship and differences between the various platforms used and injuries seen in urban warfare, aiming for tailor-made protection.

From 1949 to 1950, an acute epidemic of schistosomiasis struck several elite units of the People's Liberation Army during the Chinese Civil War that were preparing for an amphibious invasion of Taiwan. The crucial delay brought by the sudden outbreak of the disease may have cost communist forces control of the strategic island, changing the geopolitical calculus of the Pacific in the decades since.

This analysis evaluates potential reporting discrepancies of the DD2341 Form (Report of Animal Bite-Potential Rabies Exposure) submitted to a forward-deployed Rabies Advisory Board to the Theater Medical Data Store (TMDS) and Reportable Medical Event (RME) systems to identify reporting gaps that can lead to improved best practices that ensure documentation of Post Exposure Prophylaxis (PEP) of potential rabies exposures into service members (SMs) electronic medical records. ⋯ This study is the first to compare the electronic medical record data to in theater reports for potential rabies exposure in a theater of operations. The analysis suggests that some written forms generated in the USCENTCOM theater are not entered into SM Military Health System electronic medical records, indicating that electronic medical records may be a less sensitive method than in-theatre reports for rabies program surveillance in a deployed setting. There is under-reporting in electronic medical records of rabies PEP in both TMDS and RME databases. Rabies PEP is an RME according to the Armed Forces Health Surveillance Division guidelines and case definitions. There needs to be better integration of the DD2341 into the electronic medical records system.
