METHODS A supersonic helium wave hit the head of anesthetized male young adult mice with a reflected pressure of 69 psi for 0.2 ms on Day 1. Subsequently, the mice were cardioperfused on Days 2, 5, or 12. The isolated brains were subjected to diffusion tensor imaging. Reduced fractional anisotropy (FA) indicated axonal injury. RESULTS After single blast, FA showed a biphasic response in the corpus callosum with decrease on Days 2 and 12 and increase on Day 5. CONCLUSIONS Blast-induced mild traumatic brain injury in a mouse model follows a biphasic FA response within 12 days after a single blast similar to that reported for human subjects. © The Association of Military Surgeons of the United States 2020.INTRODUCTION Point-of-injury (POI) care requires immediate specialized assistance but delays and expertise lapses can lead to complications. In such scenarios, telementoring can benefit health practitioners by transmitting guidance from remote specialists. However, current telementoring systems are not appropriate for POI care. This article clinically evaluates our System for Telementoring with Augmented Reality (STAR), a novel telementoring system based on an augmented reality head-mounted display. The system is portable, self-contained, and displays virtual surgical guidance onto the operating field. These capabilities can facilitate telementoring in POI scenarios while mitigating limitations of conventional telementoring systems. METHODS Twenty participants performed leg fasciotomies on cadaveric specimens under either one of two experimental conditions telementoring using STAR; or without telementoring but reviewing the procedure beforehand. An expert surgeon evaluated the participants' performance in terms of completion time, number of errors, and procedure-related scores. Additional metrics included a self-reported confidence score and postexperiment questionnaires. RESULTS STAR effectively delivered surgical guidance to nonspecialist health practitioners participants using STAR performed fewer errors and obtained higher procedure-related scores. CONCLUSIONS This work validates STAR as a viable surgical telementoring platform, which could be further explored to aid in scenarios where life-saving care must be delivered in a prehospital setting. © Association of Military Surgeons of the United States 2020.

This lack of definition has hindered efforts to develop standardized concussion monitoring, safety testing, and protective countermeasures. To overcome this knowledge gap, we have developed, tested, and deployed a head impact monitoring mouthguard (IMM) system.  https://www.selleckchem.com/products/FK-506-(Tacrolimus).html  MATERIALS AND METHODS The IMM system was first calibrated in 731 laboratory tests. Versus reference, Laboratory IMM data fit a linear model, with results close to the ideal linear model of form y = x + 0, R2 = 1. Next, during on-field play involving n = 54 amateur American athletes in football and boxing, there were tens of thousands of events collected by the IMM. A total of 890 true-positive head impacts were confirmed using a combination of signal processing and National Institute of Neurological Disorders and Stroke/National Institutes of Health Common Data Elements methods. RESULTS The median and 99th percentile of peak scalar linear acceleration and peak angular acceleration were 20 and 50 g and 1,700 and 4,600 rad/s2, respectively. No athletes were diagnosed with concussion. CONCLUSIONS While these data are useful for preliminary human tolerance limits, a larger population must be used to quantify real-world dose response as a function of impact magnitude, direction, location, and accumulation.

MATERIALS AND METHODS knowledge translation best practices were integrated into a training workshop with the goal to increase provider adoption of the VHB. Providers were trained at three sites and provided feedback before the training, post-training, and at 3, 6, and 12 months following the training. RESULTS Pretraining, less then 22% of respondents indicated that they had used the VHB in clinical practice; post-training, 89% of respondents reported their intent to use the VHB. At 3 and 6 months, 82% of evaluation respondents indicated actual use of the VHB. CONCLUSIONS Using a public-facing technology, this study successfully integrated knowledge translation methods within an existing provider training program. Implementation planning should be deliberate and consider a target site's capacity for new ideas and potential adoption barriers. Lessons learned have implications for future efforts to bridge the gap between research and practice in improving the quality and impact of clinical care. © Association of Military Surgeons of the United States 2020.

METHODS We retrospectively analyzed emergency medical services (EMS) run reports from January 1, 2017 to November 12, 2017 to hospital access points to assess patients who were initially denied access to the MTF. Time from EMS activation until patient delivery at the emergency department, number of time-sensitive complaints, number of time-sensitive conditions, and number of unauthorized access attempts are reported. RESULTS During the 11-month period of review, 42 delays of care related to EMS activation by the sentry at hospital access points were identified. Of the 42, 14 were associated with a time-sensitive complaint, 2 with time-sensitive conditions, and none were unauthorized access attempts. CONCLUSION We identify the potential for patient harm due to delays in care resulting from the security protocols at our MTF.
