Web-based interventions hold great promise for the dissemination of best practices to clinicians, and investment in these resources has grown exponentially. Yet, little research exists to understand their impact on intended objectives. ⋯ This study demonstrates the importance of methodologically rigorous evaluations of participant engagement with web-based interventions. These approaches provide insight into who accesses these tools, when, how, and with what results, which can be translated into their strategic design, evaluation, and dissemination.

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.

Blast overpressure health hazard assessment is required prior to fielding of weapon systems that produce blast overpressures that pose risk of auditory and nonauditory blast lung injuries. The anthropomorphic blast test device (ABTD) offers a single device solution for collection of both auditory and nonauditory data from a single blast at anthropometrically correct locations for injury risk assessment. It also allows for better replication of personnel positioning during weapons firings. The ABTD is an update of the blast test device (BTD), the current Army standard for collection of thoracic blast loading data. Validation testing of the ABTD is required to ensure that lung injury model validated using BTD collected test data and sheep subjects is still applicable when the ABTD is used. ⋯ The ABTD was validated successfully for open field tests. For occupational blast injury assessments, ABTD can be used in place of the BTD and provide enhanced capabilities.

Hemorrhage control is the top priority in far-forward care. Preclinical studies are essential for determining safety and efficacy before novel therapeutics can be tested in humans. Unfortunately, poor methodological quality jeopardizes translational potential. ⋯ Methodological quality was poor. Although funding agencies actively promote good scientific practice, investigators have been slow to comply. Poorly executed and reported animal research is an ethical and translational issue, wasting animals and potentially harming patients. To properly assess the therapeutic benefit of novel interventions, investigators must rely less on rote hypothesis testing, develop skills in experimental design and quantitative analysis, and comply with best-practice reporting guidelines.
