The Military Medicine Leadership Life Cycle: A Model for Longitudinal Leadership Development in Medicine-Undergraduate and Graduate Medical Education.

Physicians must be leaders more than ever with innumerable challenges. Despite this need, there is a paucity of consistent leadership development (LD) from medical student to staff physician. Military medicine has additional challenges-working within a large health care organization, constant turnover, working in a variety of contexts-that make the need for LD even more pressing.

Coach-Like Skills for Educators: An Engaging and Applicable Workshop.

Equipping students with coach-like skills is one way to motivate and prepare them as future educators. Herein, we describe an engaging and applicable workshop designed to teach five skills to improve interactions with others. Educators who acquire coach-like skills may positively impact learners and enhance their development.

Impact on Faculty's Own Development When Assessing Student Performance.

Introduction: Assessing learner performance is a primary focus within simulation-based education in order to prepare students with the knowledge and skills they will need going forward in their careers. In order to properly conduct these assessments of learner performance, faculty must be adequately trained on the scenario, expectations, assessment measures, and debriefing. During Operation Bushmaster, a five-day "deployment" for learners, faculty assess students as they rotate through different leadership roles.

Students' Leadership Development During a High-fidelity Military Medical Field Practicum.

Introduction: Leadership development is a cornerstone aspect of military medical education. Operation Bushmaster, a medical field practicum (MFP) conducted by the USU, tests fourth-year medical students' clinical skills and leadership acumen in an operational environment. No studies have examined students' perceptions of their own leadership development during this MFP.

Undergraduate Medical Education Leader Performance Predicts Postgraduate Military Leader Performance.

Introduction: Developing physicians as leaders has gained attention across the United States. Undergraduate medical education (UME) and graduate medical education (GME) leader development programs have increased. During postgraduate years (PGY), graduates bring their leadership education to the bedside; however, associations between leader performance in medical school and GME is largely unknown.

A Pilot Study of Whole-Blood Transcriptomic Analysis to Identify Genes Associated with Repetitive Low-Level Blast Exposure in Career Breachers.

Repetitive low-level blast exposure is one of the major occupational health concerns among US military service members and law enforcement. This study seeks to identify gene expression using microRNA and RNA sequencing in whole-blood samples from experienced breachers and unexposed controls. We performed experimental RNA sequencing using Illumina’s HiSeq 2500 Sequencing System, and microRNA analysis using NanoString Technology nCounter miRNA expression panel in whole-blood total RNA samples from 15 experienced breachers and 14 age-, sex-, and race-matched unexposed controls.

Learning to Lead: 10 Leadership Lessons From Operation Bushmaster.

Medical students at the Uniformed Services University of the Health Sciences participate in a leadership curriculum designed to develop leadership skills. Operation Bushmaster is a 5-day field practicum designed to test these skills. In this article, we describe 10 leadership lessons learned during Operation Bushmaster applicable to all leaders.

Neuronally-derived tau is increased in experienced breachers and is associated with neurobehavioral symptoms.

Military and law enforcement breachers are exposed to many low-level blasts during their training and occupational experiences in which they detonate explosives to force entry into secured structures. There is a concern that exposure to these repetitive blast events in career breachers could result in cumulative neurological effects. This study aimed to determine concentrations of neurofilament light (NF-L), tau, and amyloid-beta 42 (Aβ42) in serum and in neuronal-derived extracellular vesicles (EVs) in an experienced breacher population, and to examine biomarker associations with neurobehavioral symptoms.

Hearing Loss and Irritability Reporting Without Vestibular Differences in Explosive Breaching Professionals.

Blast exposure is a potential hazard in modern military operations and training, especially for some military occupations. Helmets, peripheral armor, hearing protection, and eye protection worn by military personnel provide some acute protection from blast effects but may not fully protect personnel against cumulative effects of repeated blast overpressure waves experienced over a career. The current study aimed to characterize the long-term outcomes of repeated exposure to primary blast overpressure in experienced career operators with an emphasis on the assessment of hearing and vestibular outcomes.

Functional and Structural Neuroimaging Correlates of Repetitive Low-Level Blast Exposure in Career Breachers.

Combat military and civilian law enforcement personnel may be exposed to repetitive low-intensity blast events during training and operations. Persons who use explosives to gain entry (i.e.

Blast exposure results in tau and neurofilament light chain changes in peripheral blood.

Objectives: To evaluate how blast exposure impacts peripheral biomarkers.

Unlabelled: in military personnel enrolled in 10-day blast training.

Methods: On day 7, 21 military personnel experienced peak overpressure <2 pounds per square inch (psi); while 29 military personnel experienced peak overpressure ≥5 psi.

A Moderate Blast Exposure Results in Dysregulated Gene Network Activity Related to Cell Death, Survival, Structure, and Metabolism.

Blast exposure is common in military personnel during training and combat operations, yet biological mechanisms related to cell survival and function that coordinate recovery remain poorly understood. This study explored how moderate blast exposure influences gene expression; specifically, gene-network changes following moderate blast exposure. On day 1 (baseline) of a 10-day military training program, blood samples were drawn, and health and demographic information collected.

Acute and Chronic Molecular Signatures and Associated Symptoms of Blast Exposure in Military Breachers.

Injuries from exposure to explosions rose dramatically during the Iraq and Afghanistan wars, which motivated investigations of blast-related neurotrauma and operational breaching. In this study, military "breachers" were exposed to controlled, low-level blast during a 10-day explosive breaching course. Using an omics approach, we assessed epigenetic, transcriptional, and inflammatory profile changes in blood from operational breaching trainees, with varying levels of lifetime blast exposure, along with daily self-reported symptoms (with tinnitus, headaches, and sleep disturbances as the most frequently reported).

Sleep extension reduces pain sensitivity.

Introduction: Insufficient sleep increases pain sensitivity in healthy individuals. Additionally, extending sleep (eg, increasing nocturnal sleep time or adding a mid-day nap) has been shown to restore pain sensitivity to baseline levels in sleep deprived/restricted individuals. Whether sleep extension can reduce pain sensitivity beyond baseline levels in non-sleep restricted/deprived individuals remains unknown.

A systematic review and meta-analysis of sleep architecture and chronic traumatic brain injury.

Sleep quality appears to be altered by traumatic brain injury (TBI). However, whether persistent post-injury changes in sleep architecture are present is unknown and relatively unexplored. We conducted a systematic review and meta-analysis to assess the extent to which chronic TBI (>6 months since injury) is characterized by changes to sleep architecture.

Limited Efficacy of Caffeine and Recovery Costs During and Following 5 Days of Chronic Sleep Restriction.

Objectives: To investigate the effects of caffeine on psychomotor vigilance and sleepiness during sleep restriction and following subsequent recovery sleep.

Methods: Participants were N = 48 healthy good sleepers. All participants underwent five nights of sleep satiation (time-in-bed [TIB]: 10 hours), followed by five nights of sleep restriction (TIB: 5 hours), and three nights of recovery sleep (TIB: 8 hours) in a sleep laboratory.

Moderate blast exposure alters gene expression and levels of amyloid precursor protein.

Objective: To explore gene expression after moderate blast exposure (vs baseline) and proteomic changes after moderate- (vs low-) blast exposure.

Methods: Military personnel (N = 69) donated blood for quantification of protein level, and peak pressure exposures were detected by helmet sensors before and during a blast training program (10 days total). On day 7, some participants (n = 29) sustained a moderate blast (mean peak pressure = 7.

Functional and Molecular Correlates after Single and Repeated Rat Closed-Head Concussion: Indices of Vulnerability after Brain Injury.

Closed-head concussive injury is one of the most common causes of traumatic brain injury (TBI). Isolated concussions frequently produce acute neurological impairments, and individuals typically recover spontaneously within a short time frame. In contrast, brain injuries resulting from multiple concussions can result in cumulative damage and elevated risk of developing chronic brain pathologies.

Moderate blast exposure results in increased IL-6 and TNFα in peripheral blood.

A unique cohort of military personnel exposed to isolated blast was studied to explore acute peripheral cytokine levels, with the aim of identifying blast-specific biomarkers. Several cytokines, including interleukin (IL) 6, IL-10 and tumor necrosis factor alpha (TNFα) have been linked to pre-clinical blast exposure, but remained unstudied in clinical blast exposure. To address this gap, blood samples from 62 military personnel were obtained at baseline, and daily, during a 10-day blast-related training program; changes in the peripheral concentrations of IL-6, IL-10 and TNFα were evaluated using an ultrasensitive assay.

Sleep deprivation impairs recognition of specific emotions.

Emotional processing is particularly sensitive to sleep deprivation, but research on the topic has been limited and prior studies have generally evaluated only a circumscribed subset of emotion categories. Here, we evaluated the effects of one night of sleep deprivation and a night of subsequent recovery sleep on the ability to identify the six most widely agreed upon basic emotion categories (happiness, surprise, fear, sadness, disgust, anger). Healthy adults (29 males; 25 females) classified a series of 120 standard facial expressions that were computer morphed with their most highly confusable expression counterparts to create continua of expressions that differed in discriminability between emotion categories (e.

Caffeine and Performance.

The role of caffeine in enhancing performance has been studied for years, and there is no doubt that caffeine can be performance enhancing. Also, a wealth of information allows for an interesting distinction between physical and cognitive performance. Most adults in America consume moderate doses of caffeine in various forms on a daily basis as caffeine is typically found in coffee, tea, soft drinks, dietary supplements, energy drinks, energy shots, and chocolate, as well as over-the-counter pills and gums.

The Revised Neurobehavioral Severity Scale (NSS-R) for Rodents.

Motor and sensory deficits are common following traumatic brain injury (TBI). Although rodent models provide valuable insight into the biological and functional outcomes of TBI, the success of translational research is critically dependent upon proper selection of sensitive, reliable, and reproducible assessments. Published literature includes various observational scales designed to evaluate post-injury functionality; however, the heterogeneity in TBI location, severity, and symptomology can complicate behavioral assessments.
