This study compared the relationship between height (HT), body mass (BM), and body mass index (BMI) of female trainees and active duty female soldiers and their performance on simulated common soldiering tasks (CSTs) with high physical demands. ⋯ Female trainees and soldiers who are taller and heavier with a higher BMI may demonstrate better performance on CSTs required of all soldiers. In addition to task-specific training, performance of CSTs may be enhanced in tasks requiring strength and power by recruiting and retaining taller and heavier females with a higher BMIs. Allowances should be considered for soldiers and trainees who can successfully perform soldiering tasks with high physical demands despite less desirable anthropometric measurements.

This article presents an emerging capability to project damage control procedures far forward for situations where evacuation to a formal surgical team is delayed. Specifically, we demonstrate the plausibility of using a wearable augmented reality (AR) telestration device to guide a nonsurgeon through a damage control procedure. ⋯ A nonsurgeon, using a wearable commercial on-visual-axis telestration system, successfully performed a damage control procedure, demonstrating the plausibility of this approach.

There is a tremendous opportunity to modernize the pharmaceutical manufacturing industry-relinquishing outdated machines that have been used for decades, and replacing them with state-of-the-art equipment that reflect more contemporary advanced technologies. This article describes how the implementation of continuous manufacturing, replacing outdated batch systems, can positively impact our health care sector. Important benefits will include the creation of advanced pharmaceutical manufacturing jobs in the United States, the establishment of capabilities and capacity to quickly produce drugs critical to U. ⋯ S. Government, in partnership with pharmaceutical companies, to address current issues such as drug shortages, national emergencies (eg, natural disasters or chemical, biological, radiological, or nuclear threats), the Strategic National Stockpile (ie, improving response time and reducing maintenance costs), and the delivery of critical drugs to distant geographies (eg, forward military bases). The article also provides a detailed example of a critical aspect of continuous manufacturing: the ability to overcome technical challenges encountered by batch technologies.

Severe trauma to the spinal cord leads to a near complete loss of blood flow at the injury site along with significant hypoperfusion of adjacent tissues. Characterization and monitoring of local tissue hypoperfusion is currently not possible in clinical practice because available imaging techniques do not allow for assessment of blood flow with sufficient spatial and temporal resolutions. The objective of the current study was to determine whether ultrafast contrast-enhanced ultrasound (CEUS) imaging could be used to visualize and quantify acute hemodynamic changes in a rat traumatic spinal cord injury (SCI) model. ⋯ We conclude that CEUS has the spatial and temporal sensitivity and resolution to visualize local tissue perfusion and vessel architecture, which maybe useful clinically to determine injury extent and severity in patients with SCI.

To establish a rabbit model of posterior penetrating eye injury as a platform to test potential therapeutics. ⋯ These data show that ocular fibrosis can be detected within 14 days after initial injury, with more severe fibrosis detected at 28 days postinjury. These results will be used to determine the optimal time points for later studies designed to test treatment strategies.
