Discharge Opioid Dose Indirectly Associated With Functional Outcomes 2 Weeks After Shoulder and Knee Arthroscopy in a US Military Sample.

Postsurgical opioid utilization may be directly and indirectly associated with a range of patient-related and surgery-related factors, above and beyond pain intensity. However, most studies examine postsurgical opioid utilization without accounting for the multitude of co-occurring relationships among predictors. Therefore, this study aimed to identify factors associated with opioid utilization in the first 2 weeks after arthroscopic surgery and examine the relationship between discharge opioid prescription doses and acute postsurgical outcomes. In this prospective longitudinal observational study, 110 participants undergoing shoulder or knee arthroscopies from August 2016 to August 2018 at Walter Reed National Military Medical Center completed self-report measures before and at 14 days postoperatively. The association between opioid utilization and both patient-level and surgery-related factors was modeled using structural equation model path analysis. Participants who were prescribed more opioids took more opioids, which was associated with worse physical function and sleep problems at day 14, as indicated by the significant indirect effects of discharge opioid dose on day 14 outcomes. Additional patient-level and surgery-related factors were also significantly related to opioid utilization dose and day 14 outcomes. Most participants had opioid medications leftover at day 14. Excess opioid prescribing was common, did not result in improved pain alleviation, and was associated with poorer physical function and sleep 14 days after surgery. As such, higher prescribed opioid doses could reduce subacute functioning after surgery, without benefit in reducing pain. Future patient-centered studies to tailor opioid postsurgical prescribing are needed.

Evaluating WIC Engagement andFood Insecurity Among Active Duty Military Families.

Nearly a quarter of active duty service members identified as food insecure in a 2022 Department of Defense report. Food insecurity impacts military readiness, retention, and recruitment. The Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a federal food supplementation program that can mitigate food insecurity for service members with children less than 5 years of age. To date, there is a lack of standardized screening for WIC eligibility or enrollment for service members and their families. This project sought to evaluate WIC awareness and enrollment as well as the prevalence of food insecurity at Walter Reed National Military Medical Center. A 26-question survey was developed to assess WIC awareness, source of WIC information, food insecurity, and nutritional insecurity. Our team developed and utilized a novel WIC screening algorithm to rapidly screen families for WIC eligibility. These tools were administered to families presenting for care at the Walter Reed National Military Medical Center pediatrics and obstetric outpatient clinics during the month of July 2022. This study was approved by the institutional review board at Walter Reed. A total of 108 (25%) of the 432 surveyed participants were eligible for WIC, with odds of WIC eligibility increasing for lower-ranking and younger service members. Of the 432 participants, 354 (81.9%) were aware of WIC. Enlisted service members were more likely than officers to know about WIC (P = 0.03), and of the 354 participants aware of WIC, a higher proportion of enlisted rank respondents learned about WIC from a military source (P = 0.01). Among the 108 participants eligible for WIC, only 38 (35.2%) reported being enrolled in WIC. Among WIC-eligible respondents who knew about WIC, being enrolled in the WIC program was not associated with rank, branch of service, sponsor gender, or sponsor age. Despite proven efficacy, WIC remains an underutilized resource for eligible military families. Our results show that a standardized screening approach at Walter Reed National Military Medical Center increased identification of WIC-eligible active duty service members by 180%, with approximately $150,000 a year in increased food supplementation benefits. Military healthcare and readiness leaders should embrace efforts to increase knowledge of, referral to, and enrollment in WIC to increase family health, well-being, and military family readiness.

Patient Engagement and Provider Effectiveness of a Novel Sleep Telehealth Platform and Remote Monitoring Assessment in the US Military: Pilot Study Providing Evidence-Based Sleep Treatment Recommendations.

Sleep problems are common and costly in the US military. Yet, within the military health system, there is a gross shortage of trained specialist providers to address sleep problems. As a result, demand for sleep medicine care far exceeds the available supply. Telehealth including telemedicine, mobile health, and wearables represents promising approaches to increase access to high-quality and cost-effective care. The purpose of this study was to evaluate patient engagement and provider perceived effectiveness of a novel sleep telehealth platform and remote monitoring assessment in the US military. The platform includes a desktop web portal, native mobile app, and integrated wearable sensors (ie, a commercial off-the-shelf sleep tracker [Fitbit]). The goal of the remote monitoring assessment was to provide evidence-based sleep treatment recommendations to patients and providers. Patients with sleep problems were recruited from the Internal Medicine clinic at Walter Reed National Military Medical Center. Patients completed intensive remote monitoring assessments over 10 days (including a baseline intake questionnaire, daily sleep diaries, and 2 daily symptom surveys), and wore a Fitbit sleep tracker. Following the remote monitoring period, patients received assessment results and personalized sleep education in the mobile app. In parallel, providers received a provisional patient assessment report in an editable electronic document format. Patient engagement was assessed via behavioral adherence metrics that were determined a priori. Patients also completed a brief survey regarding ease of completion. Provider effectiveness was assessed via an anonymous survey. In total, 35 patients with sleep problems participated in the study. There were no dropouts. Results indicated a high level of engagement with the sleep telehealth platform, with all participants having completed the baseline remote assessment, reviewed their personalized sleep assessment report, and completed the satisfaction survey. Patients completed 95.1% of sleep diaries and 95.3% of symptom surveys over 10 days. Patients reported high levels of satisfaction with most aspects of the remote monitoring assessment. In total, 24 primary care providers also participated and completed the anonymous survey. The results indicate high levels of perceived effectiveness and identified important potential benefits from adopting a sleep telehealth approach throughout the US military health care system. Military patients with sleep problems and military primary care providers demonstrated high levels of engagement and satisfaction with a novel sleep telehealth platform and remote monitoring assessment. Sleep telehealth approaches represent a potential pathway to increase access to evidence-based sleep medicine care in the US military. Further evaluation is warranted.

Correlation of Impulse Oscillometry with Spirometry in Deployed Military Personnel with Airway Obstruction.

Evaluation of chronic respiratory symptoms in deployed military personnel has been conducted at Brooke Army Medical Center as part of the Study of Active Duty Military for Pulmonary Disease Related to Environmental Deployment Exposures III study. Although asthma and airway hyperreactivity have been the most common diagnoses, the clinical findings in these patients may be multifactorial. This study aims to evaluate the utility of impulse oscillometry (IOS) in diagnosing airway obstruction in patients undergoing multiple pulmonary function testing (PFT) studies. Military personnel referred for deployed-related pulmonary symptoms underwent a standardized evaluation at Brooke Army Medical Center and Walter Reed National Military Medical Center over a 5-year span. Initial studies included laboratory tests, high-resolution computed tomography imaging, cardiac evaluation with electrocardiogram, and echocardiography. PFT consisted of full PFTs, forced inspiratory/expiratory pressures, post-spirometry bronchodilator testing, IOS, exhaled nitric oxide, and methacholine challenge testing. A total of 360 patients have completed an evaluation to date. In this cohort, 108 patients (30.0%) have evidence of obstruction by spirometry, whereas 74 (20.6%) had IOS values of both an R5 > 150% and X5 < -1.5. Only 32 (8.9%) had evidence of obstruction by both spirometry and IOS, whereas 210 (57.3%) had neither. A comparison among R5 (resistance at 5 Hz), R20 (resistance at 20 Hz), and X5 (reactance at 5 Hz) was performed in those individuals with and without spirometric obstruction. R5 (% predicted) was 156.2 ± 57.4% (obstruction) vs. 129.1 ± 39.6% (no obstruction) (P < .001); R20 (% predicted) was 138.1 ± 37.7% (obstruction) vs. 125.3 ± 31.2% (no obstruction) (P = .007); and X5 (cmH2O/L/s) was -1.62 ± 1.28 (obstruction) vs. -1.25 ± 0.55 (no obstruction) (P < .001). Impulse oscillometry has been advocated as a supplemental pulmonary function test to aid in the diagnosis of airway obstruction. The use of IOS has been primarily used in pediatrics and elderly populations as a validated tool to establish a diagnosis of airway obstruction but is limited in the adult population because of a well-validated set of reference values. Prior studies in adults have most often demonstrated a correlation with an elevated R5 > 150%, elevated resonant frequency, and a negative X5 < -1.5 or a decrease of 30 to 35% in R5 post-bronchodilator. Impulse oscillometry may serve as an adjunct to diagnosis but likely cannot replace a standard spirometric evaluation. Our study highlights the future utility for diagnosing early obstructive disease in the symptomatic individual.

Improving Pre-exposure Prophylaxis Counseling at a Military Women's Health Care Clinic to Champion CDC and Defense Health Agency Recommendations.

The CDC updated their guidelines in 2021 to recommend all doctors speak about pre-exposure prophylaxis (PrEP) against human immunodeficiency virus infection with all sexually active patients. In addition, there is a demonstrated need for physicians to counsel patients on PrEP to achieve military readiness. Results from the 2018 Health Related Behaviors Survey indicate 21.8% of U.S. service members were at high risk for human immunodeficiency virus. This improvement project aimed to assess deficiencies in providers' knowledge before and after an educational intervention and describe policies clinics can adopt to adhere to CDC recommendations. A pre-intervention survey was distributed to providers at the Walter Reed National Military Medical Center Gynecologic Surgery and Obstetrics clinic. Based on results, an educational lecture and standardized intake form were developed. Following the intervention, a post-survey was distributed to providers. A chart review was performed to determine whether PrEP counseling increased following the intervention. Forty-seven gynecologic providers were sent a pre- and post-intervention survey. Thirty-seven individuals completed the pre-intervention survey (response rate 78.72%), whereas 18 people completed the post-intervention survey (response rate 38.30%). Descriptive analysis suggested comfort counseling on PrEP, comfort with Defense Health Agency guidance on PrEP, and knowledge of PrEP all increased. In terms of the chart review, 81 charts were reviewed pre- and post-intervention. Although we failed to meet our target counseling rate of 70%, the number of patients who were counseled on or prescribed PrEP following our intervention was statistically significant (P = .013). This improvement project increased provider knowledge and comfort with PrEP, but only marginally affected behavior changes among providers. This failure may be related to the specific clinic in which the study was implemented. Further research is needed to facilitate routine counseling of PrEP among military women's health care providers.

Pediatric Obesity Prevalence inthe U.S. Military Health System, Fiscal Years 2012-2018.

Obesity prevalence in Military Health System (MHS) children has been reported through fiscal year (FY) 2012 as consistently lower than in the general population. Our study reports military pediatric overweight, obesity, and severe obesity prevalence through FY2018. We compared FY2018 prevalence to a sample of the general population using National Health and National Health and Nutrition Examination Survey (NHANES) 2017-2018 data. The MHS Data Repository was queried for all children aged 2-17 years seen at any military treatment facility between FY2012 and FY2018. We calculated overweight and obesity (classes 1, 2, and 3) prevalence for each FY and performed subgroup analysis for sex, age, and sponsor rank. We also compared FY2018 to NHANES 2017-2018 data. This study was approved by the Walter Reed National Military Medical Center Institutional Review Board. The prevalence of overweight and obesity was stable from FY2012 (14.4% and 11.3%, respectively) to FY2018 (14.1% and 10.7%). Rates of classes 2 and 3 obesity combined were also stable at around 2.5% of all children. In FY2018, obesity prevalence was greater in assigned males, increased with age, and was highest in 16-17-year-olds (odds ratio: 2.75) and children with an enlisted military sponsor (odds ratio: 1.78). Compared to NHANES, MHS children had lower rates of obesity (10.7% versus 19.3%) with a smaller proportion of severe obesity (24% versus 32%). The prevalence of pediatric overweight and obesity in the MHS was stable over time. Disparities were observed between age and sponsor rank groups. When compared to the general population, overall obesity prevalence was lower in younger military children. Further research is needed to explore disparities and to identify optimal strategies to mitigate the increase in obesity prevalence with age.

The SOAP Feedback Training Program.

Accessible and efficient opportunities for health professional faculty to hone feedback skills are limited. In addition, feedback models to apply to the objective structured clinical examination (OSCE) setting are lacking. Annually, paediatric interns from Children's National Hospital and Walter Reed National Military Medical Center participate in an OSCE, which includes faculty observation and immediate feedback to trainees. In 2018, we incorporated the subjective, objective, assessment, plan (SOAP) Feedback Training Program during 20 min of the pre-OSCE faculty orientation. The SOAP Feedback Training Program introduced the SOAP feedback model (subjective, objective, assessment, plan), facilitated practice in pairs and distributed a cognitive aid referencing the model. We evaluated the quality of faculty feedback exchanges during the 2018 OSCE via retrospective video review using the Direct Observation of Clinical Skills Feedback Scale (DOCS-FBS). We compared the results to the 2015 initial evaluation and used focus groups to understand how and why faculty feedback changed. Comparison of the initial evaluation to the post-SOAP Feedback Training Program intervention data using a Wilcoxon signed rank test showed statistically significant improvement in six of eight feedback items on the DOCS-FBS. Causal coding of focus group transcripts revealed that the SOAP Feedback Training Program evoked affective responses, reinforced prior practice in feedback delivery, improved feedback organisation and increased feedback delivery preparation. The SOAP Feedback Training Program is an effective intervention to teach the SOAP feedback model and improve faculty feedback quality in an OSCE setting. It is efficient and low resource, facilitating its potential use in settings beyond the OSCE.

Characterization of initial ankle-foot prosthesis prescription patterns in U.S. Service members following unilateral transtibial amputation.

The purpose of this study was to explore relationships between patient-specific characteristics and initial ankle-foot prosthesis prescription patterns among U.S. Service members with unilateral transtibial limb loss. A retrospective review of health records identified 174 individuals with unilateral transtibial limb loss who received care at Walter Reed National Military Medical Center between 2001 and 2019. We examined patient-specific factors such as demographics, participant duty status at injury and amputation, amputation etiology, and timing between injury, amputation, and initial prescription. The type of first prescribed ankle-foot prosthesis was categorized as energy storing and return - nonarticulating, energy storing and return - articulating, or computer controlled. Sex, amputation etiology, time from injury to initial prescription, and time from amputation to initial prescription differed by type of initial ankle-foot prosthesis prescription. Service members with shorter intervals between injury-initial prescription and amputation-initial prescription, and those injured by combat blast, were more likely to receive a non-articulating device. Incorporating sex, time from injury-initial prescription, time from amputation-initial prescription, and amputation etiology as predictors of prosthesis type, we were able to correctly classify 72% of all first prostheses prescribed. Patient-specific characteristics such as sex, the time between injury-initial prescription, time from amputation-initial prescription and amputation etiology are essential characteristics that influence initial ankle-foot prosthesis prescription patterns in U.S. Service members.

Geospatial Assessment to Improve Time to Treatment (GAITT)

IntroductionGeographic information systems (GIS) can optimize trauma systems by identifying ways to reduce time to treatment. Using GIS, this study analyzed a system in Maryland served by Johns Hopkins Suburban Hospital and the University of Maryland Capital Region Medical Center. It was hypothesized that including Walter Reed National Military Medical Center (WRNMMC) in the Maryland trauma system in an access simulation would provide increased timely access for a portion of the local population. Materials and methodsUsing ArcGIS Online, catchment areas with and without WRNMMC were built. Catchment areas captured Johns Hopkins Suburban Hospital, University of Maryland Capital Region Medical Center, and WRNMMC at 5-, 10-, 15-, 20-, 25-, 30-, 45-, and 60-min. Various time conditions were simulated (12 am, 8 am, 12 pm, and 5 pm) on a weekday and weekend day. Data was enriched with 19 variables addressing population size, socioeconomic status, and diversity. ResultsAll catchment areas benefited on at least one time-day simulation, but the largest increases in mean population coverage were in the 0-5 (10.5%), 5-10 (12.3%), and 10-15 min (5.7%) catchment areas. These areas benefited regardless of time-day simulation. The lowest increase in mean population coverage was seen in the 20-25-min catchment area (0.1%). Subgroup analysis revealed that all socioeconomic status and diversity groups gained coverage. ConclusionsThis study suggests that incorporating WRNMMC into the Maryland trauma system might yield increased population coverage for timely trauma access. If incorporated, WRNMMC may provide nonstop or flexible coverage, possibly in different traffic scenarios or while civilian centers are on diversion status.

Abstract B054: Inherited mutations of DNA damage repair genes in a racially diverse cohort of men with prostate cancer

Abstract Introduction: DNA damage repair genes (DDRGs) play an important role in genomic stability and mutations in DDRGs contribute to clinically significant prostate cancer (PCa). However, the association of germline mutations in DDRGs with PCa progression and therapeutic stratification remain to be defined in African American (AA) men. Our objective was to genomically profile all known DDRGs and provide ancestry specific findings, focusing on PCa patients with African ancestry. Methods: Germline mutations in all DDRGs (N=276) was evaluated by whole genome sequence (WGS) analysis of archived blood DNA samples from 600 PCa patients (300 AA and 300 CA) who underwent primary treatment at Walter Reed National Military Medical Center. The WGS mean coverage exceeded 37x. Principal Component Analysis using the Peddy program was conducted, and ancestry prediction was based on a machine learning approach using 1000G as reference. Variant frequencies in CPDR PCa patients were compared to variant frequencies available from the Exome Aggregation Consortium (ExAC) controls with no PCa. Data analysis approaches included single variant association, gene-based total frequency test and clinico-pathological associations for germline mutations. All statistical tests were two-sided, and FDR adjusted. FDR &amp;lt; 0.05 was set as significance threshold. Results: Comprehensive analysis of 276 DDRGs revealed that germline mutation (Pathogenic/Likely Pathogenic; P/LP) carrier rate was 23.5%, which is three times higher than reported before in both AA and CA men, due to our unbiased WGS approach. We found that only 13 of the 46 DDRGs identified with P/LP mutations were common to AA and CA men, demonstrating clear disparity along ancestry lines. Importantly, RAD family genes (RAD54L, RAD54B, RAD51), which are potentially targetable, as well as PMS2 and BRCA1, were among the most frequently mutated DDRGs in AA, but not in CA men. Germline mutations in RAD51 and PMS2 were enriched in AA cohort as compared to CA men (P 0.01 and 0.03 respectively), while germline mutations in FANCA were significantly enriched in CA cohort (P &amp;lt; 0.01). Pathway analysis showed that the HR pathway (with 15 mutations) was associated with faster disease progression to biochemical recurrence (BCR) (P &amp;lt;0.05), while the NHEJ pathway (with three mutations) was found to be marginally associated with metastasis (p &amp;lt;0.05). Additionally, we found that germline mutations in DDRGs was associated with shorter time to BCR (P &amp;lt;0.05) in AA patients, but not in CA men. Conclusion: Our findings highlight distinct DDRG germline mutation profile across AA and CA prostate cancer men. This may help refine patient stratification for specific targeted therapeutic options especially for under-studied AA men. Future replication studies in an independent patient cohort are warranted to validate our findings. Citation Format: Indu Kohaar, Xijun Zhang, Gregory Chesnut, Clifton Dalgard, Matthew D.

Mental Health Stigma in Active Duty Service Members Receiving Mental Health Services.

Mental health treatment is a service for military service members who have experienced psychological injury or trauma. Unfortunately, the stigma associated with treatment can prevent many service members from seeking and receiving treatment designed to help them recover. Previous studies have examined the impacts of stigma among military personnel as well as civilians; however, stigma among service members currently receiving mental health treatment is unknown. The purpose of this study is to understand the relationships between stigma, demographic variables, and mental health symptoms in a sample of active duty service members receiving mental health services in a partial hospitalization program. This cross-sectional, correlational study collected data from participants in the Psychiatric Continuity Services clinic at Walter Reed National Military Medical Center, which offers a four-week partial hospitalization program specializing in trauma recovery for active duty service members of all branches. The data from behavioral health assessments were gathered over a 6-month timespan, including the Behavior and Symptom Identification Scale-24, Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-item scale, and Post-traumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). Stigma was measured using the Military Stigma Scale (MSS). The demographic data collected included military rank and ethnicity. Pearson correlations, t-tests, and linear regression were used to further explore the relationships between the MSS scores, demographic covariates, and behavioral health measures. In unadjusted linear regression models, non-white ethnicity and higher behavioral health assessment intake measures were associated with higher MSS scores. However, after adjusting for gender, military rank, race, and all mental health questionnaires, only Post-traumatic Stress Disorder Checklist for DSM-5 intake scores remained associated with MSS scores. No relationship between gender or military rank and average stigma score was observed in either the unadjusted or adjusted regression models. One-way analysis of variance detected a statistically significant difference between the white/Caucasian group and Asian/Pacific Islander group and a near significant difference between white/Caucasian group and black/African American group. The rates of stigma were higher in non-whites than whites. In this active duty military cohort, greater mental health stigma was associated with greater severity of mental health symptoms, especially post-traumatic stress symptoms. Some evidence found that ethnicity may also play a role in stigma score differences, particularly in the Asian/Pacific Islander group. Service providers could consider assessing mental health stigma to meet the clinical needs of their patients within the context of their willingness to obtain and adhere to treatment. Anti-stigma efforts to reduce stigma and its impacts on mental health are discussed. Additional research investigating the effect stigma has on treatment outcomes would help guide the relative importance of assessing stigma, in addition to other behavioral health realms.

Updating the Military Unique Curriculum for a Ready Medical Force.

Previous conflicts have demonstrated the impact of physician readiness on early battlefield mortality rates. To prepare for the lethal nature of today's threat environment and the rapid speed with which conflict develops, our medical force needs to sustain a high level of readiness in order to be ready to "fight tonight." Previous approaches that have relied on on-the-job training, just-in-time predeployment training, or follow-on courses after residency are unlikely to satisfy these readiness requirements. Sustaining the successes in battlefield care achieved in Iraq and Afghanistan requires the introduction of effective combat casualty care earlier and more often in physician training. This needs assessment seeks to better understand the requirements, challenges, and opportunities to include the Military Unique Curriculum (MUC) during graduate medical education. This needs assessment used a multifaceted methodology. First, a literature review was performed to assess how Military Unique Curricula have evolved since their initial conception in 1988. Next, to determine their current state, a needs-based assessment survey was designed for trainees and program directors (PDs), each consisting of 18 questions with a mixture of multiple choice, ranking, Likert scale, and free-text questions. Cognitive interviewing and expert review were employed to refine the survey before distribution. The Housestaff Survey was administered using an online format and deployed to Internal Medicine trainees at the Walter Reed National Military Medical Center (WRNMMC). The Program Director Survey was sent to all Army and Navy Internal Medicine Program Directors. This project was deemed to not meet the definition of research in accordance with 32 Code of Federal Regulation 219.102 and Department of Defense Instruction 3216.02 and was therefore registered with the WRNMMC Quality Management Division. Out of 64 Walter Reed Internal Medicine trainees who received the survey, 32 responses were received. Seven of nine PDs completed their survey. Only 12.5% of trainees felt significantly confident that they would be adequately prepared for a combat deployment upon graduation from residency with the current curriculum. Similarly, only 14.29% of PDs felt that no additional training was needed. A majority of trainees were not satisfied with the amount of training being received on any MUC topic. When incorporating additional training on MUC topics, respondents largely agreed that simulation and small group exercises were the most effective modalities to employ, with greater than 50% of both trainees and PDs rating these as most or second most preferred among seven options. Additionally, there was a consensus that training should be integrated into the existing curriculum/rotations as much as possible. Current Military Unique Curricula do not meet the expected requirements of future battlefields. Several solutions to incorporate more robust military unique training without creating any significant additional time burdens for trainees do exist. Despite the limitation of these results being limited to a single institution, this needs assessment provides a starting point for improvement to help ensure that we limit the impact of any "peacetime effect."

Hypoglossal Nerve Stimulator in the Active Duty Population: Military Readiness and Satisfaction.

Because inadequate sleep impairs mission performance, the U.S. Army regards sleep as a core pillar of soldier readiness. There is an increasing incidence of obstructive sleep apnea (OSA) among active duty (AD) service members, which is a disqualifying condition for initial enlistment. Moreover, a new diagnosis of OSA in the AD population often prompts a medical evaluation board, and if symptomatic OSA proves refractory to treatment, this may result in medical retirement. Hypoglossal nerve stimulator implantation (HNSI) is a newer implantable treatment option, which requires minimal ancillary equipment to function and may provide a useful treatment modality to support AD service members while maintaining readiness in appropriate candidates. Because of a perception among AD service members that HNSI results in mandatory medical discharge, we aimed to evaluate the impact of HNSI on military career progression, maintenance of deployment readiness, and patient satisfaction. The Department of Research Programs at the Walter Reed National Military Medical Center provided institutional review board approval for this project. This is a retrospective, observational study and telephonic survey of AD HNSI recipients. Military service information, demographics, surgical data, and postoperative sleep study results were collected from each patient.Additional survey questions assessed each service member's experience with the device. Fifteen AD service members who underwent HNSI between 2016 and 2021 were identified. Thirteen subjects completed the survey. The mean age was 44.8 years (range 33-61), and all were men. Six subjects (46%) were officers. All subjects maintained AD status following HNSI yielding 14.5 person-years of continued AD service with the implant. One subject underwent formal assessment for medical retention. One subject transferred from a combat role to a support role. Six subjects have since voluntarily separated from AD service following HNSI. These subjects spent an average of 360 (37-1,039) days on AD service. Seven subjects currently remain on AD and have served for an average of 441 (243-882) days. Two subjects deployed following HNSI. Two subjects felt that HSNI negatively affected their career. Ten subjects would recommend HSNI to other AD personnel. Following HNSI, of the eight subjects with postoperative sleep study data, five achieved surgical success defined as >50% reduction of apnea-hypopnea index and absolute apnea-hypopnea index value of <20. Hypoglossal nerve stimulator implantation for AD service members offers an effective treatment modality for OSA, which generally allows for the ability to maintain AD status, however: The impact on deployment readiness should be seriously considered and tailored to each service member based on their unique duties before implantation. Seventy-seven percent of HNSI patients would recommend it to other AD service members suffering from OSA.

Assessment of a novel continuous cleaning device using metatranscriptomics in diverse hospital environments.

Despite routine implementation of cleaning and disinfection practices in clinical healthcare settings, high-touch environmental surfaces and contaminated equipment often serve as reservoirs for the transmission of pathogens associated with healthcare-associated infections (HAIs). The current study involved the analysis of high-touch surface swabs using a metatranscriptomic sequencing workflow (CSI-Dx™) to assess the efficacy of cleanSURFACES® technology in decreasing microbial burden by limiting re-contamination. This is a non-human single center study conducted in the Emergency Department (ED) and on an inpatient Oncology Ward of Walter Reed National Military Medical Center that have followed hygienic practices during the COVID-19 pandemic environment. Although there was no difference in observed microbial richness (two-tailed Wilcoxon test with Holm correction, P > 0.05), beta diversity findings identified shifts in microbial community structure between surfaces from baseline and post-intervention timepoints (Day 1, Day 7, Day 14, and Day 28). Biomarker and regression analyses identified significant reductions in annotated transcripts for various clinically relevant microorganisms' post-intervention, coagulase-negative staphylococci and Malassezia restricta, at ED and Oncology ward, respectively. Additionally, post-intervention samples predominantly consisted of Proteobacteria and to a lesser extent skin commensals and endogenous environmental microorganisms in both departments. Findings support the value of cleanSURFACES®, when coupled with routine disinfection practices, to effectively impact on the composition of active microbial communities found on high-touch surfaces in two different patient care areas of the hospital (one outpatient and one inpatient) with unique demands and patient-centered practices.

Investigating post-mild traumatic brain injury neuromuscular function and musculoskeletal injury risk: A protocol for a prospective, observational, case–controlled study in service members and active individuals

IntroductionMusculoskeletal injury (MSKI) risk is increased following mild traumatic brain injury (mTBI). Increased MSKI risk is present up to 2 years following post-mTBI return-to-duty/activity relative to both non-mTBI peers and...

Nondisparate Survival of Non-Hispanic Black Women With Breast Cancer Despite Less Favorable Pathology: Effect of Access to and Provision of Care Within a Military Health Care System.

Breast cancer mortality rates are 40% higher in non-Hispanic Blacks (NHBs) than in non-Hispanic White (NHWs) in the United States. All women treated within the Murtha Cancer Center at Walter Reed National Military Medical Center (MCC/WRNMMC) have health insurance and are provided multidisciplinary health care. Pathological factors and outcomes of NHBs and NHWs treated within the MCC/WRNMMC were evaluated to determine whether equal-access health care reduces disparate phenotypes and survival between the racial groups. Between 2001 and 2018, 368 NHB and 819 NHW women were diagnosed with breast cancer at MCC/WRNMMC. Differences between NHBs and NHWs in epidemiological and pathological characteristics were evaluated. Overall and breast cancer-specific 5- and 10-year survival rates were compared between races. Compared with NHWs, NHBs were significantly more likely to have a body mass index ≥30 kg/m2, to be unmarried, to have tumors of higher grade, later stage, with lymph node metastases, and to be hormone receptor negative (HR-)/human epidermal growth factor receptor 2 positive (HER2+) or triple negative. After adjustment for demographic factors, NHBs remained significantly more likely to have tumors diagnosed at a higher grade and later stage, and to be HR-/HER2+ or triple negative. Neither 5- nor 10-year overall or breast cancer-specific survival differed significantly between the racial groups after adjusting for demographic and pathological variables. Despite having tumors with less favorable pathological characteristics, overall and disease-free survival disparities were not observed for NHBs treated at MCC/WRNMMC. These data suggest that survival disparities of NHBs with breast cancer can be diminished with provision of quality care.
