Multimodal monitoring is the use of data from multiple physiological sensors combined in a way to provide individualized patient management. It is becoming commonplace in the civilian care of traumatic brain-injured patients. We hypothesized we could bring the technology to the battlefield using a noninvasive sensor suite and an artificial intelligence-based patient management guidance system. ⋯ We developed a design and tested the feasibility of a system that would allow the use of physiological biomarkers as a management tool in forward care. A key feature is the modular design that allows the system to adapt to changes in sensors, resources, and context as well as to updates in guidelines as they are developed. Continued work consists of further validation of the concept with simulated scenarios.

Musculoskeletal injuries (MSIs) pose a significant problem for active duty service members (ADSMs). MSIs may compromise readiness and are one of the main reasons for separation from the Navy and long-term disability. Implementation of optimal treatment strategies rests on understanding the characteristics of MSI complaints in a given population. This study reports on the frequency and nature of MSI complaints of ADSMs seeking care at a military treatment facility (MTF). ⋯ Back and knee injuries were most prevalent in ADSMs reporting an MSI at a Navy shore-based MTF. Shoulder injuries were also common. Of interest, 80% of ADSMs reported at least one MSI comorbidity and 80% reported chronic injury in this study. These rates are higher than those found in a previous study of ADSMs deployed on a carrier. This is notable because chronicity and multiple MSIs are obstacles to readiness. Our findings suggest that ADSMs reporting to shore-based facilities may be at higher risk for disability than their deployed counterparts. This information is important to the development of targeted care to improve readiness in this population.

Despite the significant need for mechanical ventilation in- and out-of-hospital, mechanical ventilators remain inaccessible in many instances because of cost or size constraints. Mechanical ventilation is especially critical in trauma scenarios, but the impractical size and weight of standard mechanical ventilators restrict first responders from carrying them in medical aid bags, leading to reliance on imprecise manual bag-mask ventilation. This is particularly important in combat-related injury, where airway compromise and respiratory failure are leading causes of preventable death, but medics are left without necessary mechanical ventilation. To address the serious gaps in mechanical ventilation accessibility, we are developing an Autonomous, Modular, and Portable Ventilation platform (AMP-Vent) suitable for austere environments, prolonged critical care, surgical applications, mass casualty incidents, and stockpiling. The core system is remarkably compact, weighing <2.3 kg, and can fit inside a shoebox (23.4 cm × 17.8 cm × 10.7 cm). Notably, this device is 65% lighter than standard transport ventilators and astoundingly 96% lighter than typical intensive care unit ventilators. Beyond its exceptional portability, AMP-Vent can be manufactured at less than one-tenth the cost of conventional ventilators. Despite its reduced size and cost, the system's functionality is uncompromised. The core system is equipped with closed-loop sensors and advanced modes of ventilation (pressure-control, volume-control, and synchronized intermittent mandatory ventilation), enabling quality care in a portable form factor. The current prototype has undergone preliminary preclinical testing and optimization through trials using a breathing simulator (ASL 5000) and in a large animal model (swine). This report aims to introduce a novel ventilation system and substantiate its promising performance through evidence gathered from preclinical studies. ⋯ Preclinical results from this study highlight AMP-Vent's core functionality and consistent performance across varied scenarios. AMP-Vent sets a benchmark for portability with its remarkably compact design, positioning it to revolutionize trauma care in previously inaccessible medical scenarios.

Decision-making is a complex process that relies on situational awareness and experience to create a potential list of actions while weighing the risks and benefits of each action. There is a paucity of data evaluating decision-making for individual service members (SM) during the performance of team-based military-relevant activities. Understanding individual performance and decision-making within the context of a team-based activity has potential to aid in the detection and management of mild traumatic brain injuries and assist with safe and timely return-to-duty decision making. The aim of this project was to evaluate cognitive and motor performance in healthy SM during an augmented reality military specific, team-based activity. ⋯ Reaction time to fire the first shot, time in the fatal funnel, and total trial time reflect a change in information-processing and decision-making capabilities during military specific, ecological, team-based scenarios when altering the environment inside of the room and modifying avatar movements. Future studies are planned to evaluate the effects of mild traumatic brain injury on specific aspects of military team performance.

Suicide is a prevalent problem impacting the military community. The U.S. Army recognized the need to address this complex issue; one line of effort has been to provide suicide prevention and intervention education and training that is informed by current research, doctrine, and implementation best practices. The purpose of this article is to outline and present the genesis of the Army's new suicide prevention and intervention training-"Ask, Care, Escort (ACE) Base +1"-that aligns with the DoD newly published regulation-driven initiatives. ⋯ The interagency collaborative efforts resulted in a suite of training products, "ACE Base +1" version 1.3 that is modernized in training content, delivery methods, and design. Four primary elements shaped the final products: (1) A modular framework allowing a tailored approach to mandatory training, (2) a public-health approach that focuses on earlier intervention opportunities while building trust and cohesion, (3) a training design centered on peer discussions and behavioral rehearsal, and (4) an expansion of the curriculum to be inclusive of the entire Army community. Practical implications for each element are discussed.As the program of record, "ACE Base +1" training satisfies the annual requirement for all Active Army, Army National Guard, U.S. Army Reserve, and Department of the Army (DA) civilians. Both the training content (e.g., public-health concepts) and design of "ACE Base +1" reflect a comprehensive approach, focused on developing concrete, applicable skills that support the shared responsibility to suicide prevention and intervention. Limitations, such as delayed interagency collaboration and time constraints, are discussed. Future directions include recommendations for future curriculum projects, specifically within military populations, such as interprofessional, interagency collaboration, and selecting a multidisciplinary team of subject-matter experts. Additionally, WRAIR plans to continue their support to Directorate of Prevention, Resilience and Readiness with the expansion of the +1 menu of trainings, ongoing program evaluation, and longitudinal analysis to inform future revisions and ensure the content and delivery methods remain modernized, relevant, and effective.
