Randomized Controlled Trial
Novel Phototherapy Kiosk Shows Promise as a Treatment Option for Low Vitamin D.
The purpose of this study was to demonstrate the feasibility of a phototherapy kiosk (PK) to engage community adults in health promotion and to stimulate production of circulating 25-hydroxyvitamin (OH)D as effectively as a vitamin D3 oral supplement (OS). Although optimal production of vitamin D comes from sun exposure, ultraviolet B radiation with a wavelength of 290 to 320 nm penetrates exposed skin and may produce vitamin D3 using a PK. ⋯ Programmed ultraviolet B phototherapy appears to be an efficacious alternative to oral vitamin D supplementation with consistent use.

Scarcity of operating rooms and personal protective equipment in far-forward field settings make surgical infections a potential concern for combat mortality and morbidity. Surgical and transport personnel also face infectious risks from bodily fluid exposures. Our study aimed to describe the serial, proof-of-concept testing of the SurgiBox technology: an inflatable sterile environment that addresses the aforementioned problems, fits on gurneys and backpacks, and drapes over incisions. ⋯ Analytic, in silico, and mechanical airflow modeling and benchtop testing have helped to quantify the SurgiBox system's reliability in creating and maintaining an operating room-quality surgical field within the enclosure as well as protecting the surgical team outside the enclosure. More recent and ongoing work has focused on specifying optimal use settings in the casualty chain of care, expanding support for circumferential procedures, automating airflow control, and accelerating system setup. SurgiBox's ultimate goal is to take timely, safe surgery to patients in even the most austere of settings.

Research shows that cognitive performance and emotional well-being can be significantly strengthened. A high-performance brain training protocol, Strategic Memory Advanced Reasoning Training (SMART), was developed by cognitive neuroscientists at The University of Texas at Dallas Center for BrainHealth based on 25-plus years of scientific study. Randomized controlled trials with various populations have shown that training and use of nine "SMART" strategies for processing information can improve cognitive performance and psychological health. However, the multi-week intensive training used in the laboratory is not practical for widespread use outside the laboratory. This article examines the efficacy of SMART when translated outside the laboratory to two populations (military/veterans and law enforcement) that received SMART in condensed time frames. ⋯ The results of translating to these two populations provide evidence supporting the efficacy of SMART delivered in an abbreviated time frame. The improvements in two major domains of cognitive function demonstrate that strategies can be taught and immediately applied by those receiving the training. The immediate psychological health improvements may be transient; however, the continued improvements in psychological health observed in a subset of the participants suggest that benefits may be sustainable even at later intervals.

Observational Study
Preliminary Data on Trauma Knowledge, Confidence, and Stress During Navy Trauma Training.
The Navy Trauma Training Center (NTTC) is a military-civilian partnership that provides advanced trauma training for application across the range of military operations while exposing military medical personnel to high-volume and high-acuity trauma. Few published data evaluate the outcomes of military-civilian partnerships, including NTTC. The purpose of this study is to evaluate the knowledge, confidence, and stress of NTTC participants before, at mid-point, and after completion of the program. Participants include corpsmen (HM), nurses (RNs), physician assistants (PAs), and physicians (MDs). ⋯ These preliminary data suggest that, as expected, trauma-related knowledge and confidence increase significantly with training at NTTC. Stress was low and stable over time. These data from a small sample of participants indicate NTTC training is increasing participants' trauma knowledge and confidence to care for trauma casualties. Continued collection of data in the ongoing study will allow us to determine whether these early findings persist in the overall study sample and may help inform the optimal length of training needed.

Early hemorrhage is often missed by traditional vital signs because of physiological reserve, especially in the young and healthy. We have developed a novel, wearable, wireless Doppler ultrasound patch that tracks real-time blood velocity in the common carotid artery. ⋯ In summary, a novel index from a wireless Doppler ultrasound patch may be more sensitive and specific for detecting decreased cardiac output than standard vital signs in healthy volunteers.
