Active Duty Military Service Members Research Articles

A brief mindfulness-based intervention for stress, pain, emotion and attention regulation in military service members with mild traumatic brain injury.

The primary aim of this study was to conduct an open pilot clinical trial of a brief mindfulness-based intervention for persistent postconcussion symptoms that occur after mild traumatic brain injury in military service members. For many service members, operational tempo and other time constraints may prevent them from completing a standard mindfulness-based stress reduction course. Thus, this study sought to examine the effectiveness of a five-session intervention called mindfulness-based stress, pain, emotion, and attention regulation (MSPEAR). Participants were active duty service members with a history of mild traumatic brain injury (TBI) and persisting postconcussion symptoms, all of whom were recruited from an outpatient TBI rehabilitation program at a military treatment facility. Of the 38 service members that were initially enrolled, 25 completed the 5-session MSPEAR intervention, and 20 returned for a 5-week follow-up evaluation. Questionnaires assessing perceived stress, positive affect, pain interference and catastrophizing, sleep disturbances, perceived behavioral and attention regulation, self-efficacy and satisfaction with life were administered at preintervention, postintervention, and at 5-week follow-up intervals. Neuropsychological testing at preintervention and 5-week follow-up included performance validity measures, attention, working memory, and executive function measures. T-tests were run to compare for questionnaire measures at preintervention (Time 1) to postintervention (Time 2). Repeated analysis of variances were conducted to compare questionnaire and neuropsychological measures at Time 1, Time 2, and at Time 3 which is the 5-week follow-up. Improvements in perceived stress, positive affect, behavioral regulation, metacognition, sleep disturbance, self-efficacy, and satisfaction with life were found immediately after the MSPEAR intervention and were maintained at the 5-week follow-up. Magnification and helplessness aspects of pain catastrophizing improved when comparing preintervention to the 5-week follow-up. Pain interference was not significantly different across study assessment times. Neuropsychological testing revealed improvements in sustained attention, working memory, cognitive flexibility, and inhibitory control when comparing preintervention to the 5-week follow-up assessment. The MSPEAR intervention appears to show promise as a brief and effective therapy for specific postconcussion symptoms after mild traumatic brain injury in military service members. Each of the components of MSPEAR including stress, pain catastrophizing, emotion and attention regulation showed improvements in this study, and bears further investigation in a larger scale, preferably randomized controlled trial in those active duty military service members who experience persisting symptoms after a mild traumatic brain injury.

Post-Traumatic Stress Disorder and Blast Exposure in Active-Duty Military Service Members

Objective: Active-duty military personnel in the current wars have experienced unique stressors that deviate from standard PTSD assessment and diagnosis. This situation calls for a refinement of military-related PTSD assessment. To this end, this study assessed the utility of the Trauma Symptom Inventory (TSI) in diagnosing PTSD among active-duty military personnel. The past literature has validated the TSI using populations with a small sample size. Hence, this study aimed to fill the gap by using a large sample size of 670 military members to examine whether the TSI is useful for military populations. Setting: Participants were referred to Carolina Psychological Health Services, in Jacksonville, North Carolina by military neurologists and other qualified medical officers from the Naval Hospital in Camp Lejeune, a military base located in Jacksonville, NC, for neuropsychological evaluation due to reported cognitive deficits related to military deployment (i.e., head injury due to exposure to blast injuries). Participants: Based on clinical diagnosis, comprehensive neuropsychological testing, and self-reported data, personnel were classified into four groups: blast exposure (n = 157), PTSD diagnosis (n = 90), both blast exposure and PTSD (n = 283), and neither blast exposure nor PTSD (n = 140), which helps provide a comprehensive picture of the utility of the TSI. Results: The TSI’s 10 clinical scales could distinguish between all groups. Discriminant function analysis showed that an optimally weighted combination of scales correctly predicted 66.67% of PTSD-positive cases and 35.11% of PTSD-negative cases. Conclusion: These findings provide support for the use of the TSI in the assessment of PTSD in active-duty military personnel. Due to the release of TSI-2, there is a need to replicate this data. However, the validity data has indicated a high concordance between the TSI and TSI-2, bolstering confidence in the current findings of the study.

3 Intensive Clinical Treatment and Rehabilitation for Veterans with Traumatic Brain Injury and Psychological Health Problems

Objective:Some active-duty military service members and veterans experience combinations of persistent traumatic stress, depression, suicidal ideation, anger, aggressive behavior, substance misuse, sleep disturbance, complicated grief, moral injury, headaches and migraines, chronic bodily pain, and cognitive weakness or deficits. The purpose of this study is to describe the clinical outcomes of active-duty service members and veterans who have completed the traumatic brain injury (TBI) and brain health track of a two-week intensive clinical treatment and rehabilitation program.Participants and Methods:The sample included 141 participants, with a history of TBI, in the Intensive Clinical Program (ICP). The ICP is a multidisciplinary, two-week treatment and rehabilitation program for active duty service members and veterans with complex psychological, cognitive, and physical health concerns. The program is comprised of daily individual therapy, group psychotherapy, psychoeducation, skills-building groups, and complementary and alternative medicine treatments. Participants in the ICP completed the following measures prior to initiating treatment and immediately following completion of treatment: Neurobehavioral Symptom Inventory (NSI), Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), Patient Health Questionnaire-9 (PHQ-9), Self-Efficacy for Symptom Management Scale (SE-SMS), and Patient-Reported Outcomes Measurement Information System (PROMIS)-Satisfaction with Participation in Social Roles and Activities-Short Form 8a, version 1.0 (PROMIS-S). Wilcoxon signed ranks tests were used to examine differences in scores on self-report measures from pretreatment to posttreatment for the full sample and within three subgroups stratified by age (in years: 20-34; 35-45; and 46-66). For the NSI, changes in the proportion of participants endorsing moderate or worse levels of individual symptoms from pretreatment to posttreatment were assessed using McNemar’s tests. Alpha levels were set at p<0.05 for all analyses.Results:Participants reported statistically significant improvements across all of the administered measures (NSI, PCL-5, PHQ-9, PROMIS-S, and SE-SMS) upon conclusion of treatment. Effect sizes ranged from medium to large (d=0.34-1.04) for the full sample. Effect sizes were largely consistent across age subgroups (20-34: d=0.32-1.05; 35-45: d=0.55-0.96; 46-66: d=0.28-1.05). The magnitude of change on the SE-SMS appeared to be less with increasing age (20-34: d=1.05; 35-45: d=0.69; 46-66: d=0.28). Individual item analyses for the NSI revealed statistically significant reductions in the proportion of participants endorsing moderate or greater severity from pretreatment to posttreatment for 18 of 22 symptoms.Conclusions:Active duty service members and veterans participating in the two-week TBI and brain health intensive clinical program reported considerable symptom reduction at the conclusion of the program. Further research is indicated to assess the durability of symptom reduction.

Reconsidering Vestibular/Ocular Motor Screening Cutoff Scores forConcussion.

Vestibular/Ocular Motor Screening (VOMS) is often part of a comprehensive evaluation to identify acute mild traumatic brain injury. Most of the reports describe the use of the VOMS in adolescents/young adults and not in older adults or military service members. The purpose of this study was to describe VOMS findings in healthy civilians and active duty military service members up to the age of 50 years. Seventy-seven healthy civilians between 18 and 50 years of age (22 males, age 31.8 [9.0] years) participated across three sites in addition to 40 healthy active duty service members (25 males, age 27.5 [4.9] years) from one site. Demographics, Neurobehavioral Symptom Inventory scores, mean near point convergence (NPC) distance, and Total Symptom Change (TSS) scores from the VOMS were evaluated. For civilians, the group mean NPC distance was 4.98 (3.8) cm. For military service members, the group mean NPC distance was 6.17 (4.57) cm. For civilians, the mean TSS was 1.2 (2.3) with 53.2% reporting 0 TSS, 27.3% reporting one TSS, and 19.5% reporting two or more TSS. For military service members, the mean TSS was 0.20 (0.72) with 92.5% reporting 0 TSS, 0% reporting one TSS, and 7.5% reporting two or more TSS. Age did not correlate with the mean NPC distance and TSS in healthy civilians and active duty military service members. Reconsideration of the Military Acute Concussion Evaluation, Version 2 cutoff value for abnormal mean NPC distance may be warranted to improve diagnostic accuracy in both civilian and military adult populations. Similarly, re-evaluating criteria for interpreting the TSS results of the VOMS, specifically in civilians, may be warranted.

Lifetime Traumatic Brain Injury and Risk of Post-Concussive Symptoms in the Millennium Cohort Study.

Traumatic brain injury (TBI) is prevalent among active duty military service members, with studies reporting up to 23% experiencing at least one TBI, with 10-60% of service members reporting at least one subsequent repeat TBI. A TBI has been associated with an increased risk of cumulative effects and long-term neurobehavioral symptoms, impacting operational readiness in the short-term and overall health in the long term. The association between multiple TBI and post-concussive symptoms (PCS), however, defined as symptoms that follow a concussion or TBI, in the military has not been adequately examined. Previous studies in military populations are limited by methodological issues including small sample sizes, the use of non-probability sampling, or failure to include the total number of TBI. To overcome these limitations, we examined the association between the total lifetime number of TBI and total number of PCS among U.S. active duty military service members who participated in the Millennium Cohort Study. A secondary data analysis was conducted using the Millennium Cohort Study's 2014 survey (n = 28,263) responses on self-reported TBI and PCS (e.g., fatigue, restlessness, sleep disturbances, poor concentration, or memory loss). Zero-inflated negative binomial models calculated prevalence ratios (PRs) and 95% confidence intervals (CIs) for the unadjusted and adjusted associations between lifetime TBIs and PCS. A third of military participants reported experiencing one or more TBIs during their lifetime with 72% reporting at least one PCS. As the mean number of PCS increased, mean lifetime TBIs increased. The mean number of PCS by those with four or more TBI (4.63) was more than twice that of those with no lifetime TBI (2.28). One, two, three, and four or more TBI had 1.10 (95% CI: 1.06-1.15), 1.19 (95% CI: 1.14-1.25), 1.23 (95% CI: 1.17-1.30), and 1.30 times (95% CI: 1.24-1.37) higher prevalence of PCS, respectively. The prevalence of PCS was 2.4 (95% CI: 2.32-2.48) times higher in those with post-traumatic stress disorder than their counterparts. Active duty military service members with a history of TBI are more likely to have PCS than those with no history of TBI. These results suggest an elevated prevalence of PCS as the number of TBI increased. This highlights the need for robust, longitudinal studies that can establish a temporal relationship between repetitive TBI and incidence of PCS. These findings have practical relevance for designing both workplace safety prevention measures and treatment options regarding the effect on and from TBI among military personnel.

0278 Patient Satisfaction with a Novel Sleep Telehealth Platform in the US Military

Abstract Introduction Despite a high prevalence of sleep problems, there is a gross shortage of sleep clinicians within the military health system. To increase access to care, a novel telehealth platform was designed to empower patients and clinicians to make evidence-based sleep treatment decisions. Here, we present initial results from the implementation of this novel sleep telehealth platform in two military treatment facilities (MTFs). Methods Participants (N=305) with sleep complaints were recruited remotely and/or in-person from two MTFs. Participants were predominately men (53.4%), who self-identified as White (55.4%) or Black (24.1%) race and were retired or active-duty military servicemembers (69%). Average age was 45.9 (SD=13.3) years. Participants completed a baseline assessment including standardized research questionnaires via a mobile application (WellTap®). During a 10-day remote monitoring assessment, participants completed daily sleep diaries and twice-daily mood/daytime function surveys, while wearing a commercial-off-the-shelf device (Fitbit®). A personalized sleep report including evidence-based treatment recommendations was provided. Participants completed a satisfaction survey regarding the remote monitoring assessment. Results The most commonly reported sleep problems were difficulty staying asleep (65%), insufficient sleep (61%), and snoring (40%). Most participants described their sleep quality as “a little good” (51%) or “not at all good” (27%). Thirty-nine percent of participants reported moderate to severe insomnia complaints, 38% reported moderate to severe excessive daytime sleepiness, and 22% reported moderate to severe depressive symptoms. In terms of satisfaction, participants reported the sleep assessments were “easy” to complete (92%) and would consider sleep telehealth approaches in the future (95%). The vast majority of participants preferred to continue with sleep telehealth and preferred to combine a mobile app and remote monitoring with either virtual or face-to-face provider support. Conclusion Patients at two military treatment hospitals reported high levels of satisfaction with a novel 10-day intensive remote monitoring assessment including a mobile health assessment and wrist-wearable device. Future studies should evaluate the clinical and economic impact of sleep telehealth and remote monitoring in the U.S. military.

Associations Among Stress, Internalized Weight Stigma, Emotional Eating, and Body Composition in Active-Duty Service Members Enrolling in a Randomized Controlled Trial of a Weight Management Program.

Obesity is a critical public health concern with particular relevance to US military personnel. Stress and internalized weight stigma ("stigma") may contribute to and maintain obesogenic processes and behaviors, including emotional eating. In this secondary cross-sectional analysis, we examined (1) associations among stress and stigma with emotional eating and body fat percentage (BF%), (2) whether stress explains the association between stigma and emotional eating, and (3) whether emotional eating explains associations between stress and stigma with BF%. Active-duty military service members (N = 178) completed BF% assessment and questionnaires assessing stress, stigma, and emotional eating. Structural equation modeling path analyses showed that stress and stigma were both significantly associated with emotional eating (b = 0.35, p < 0.001 and b = 0.23, p < 0.001, respectively) and with BF% (b = 0.38, p < 0.001 and b = 0.29, p < 0.001, respectively) such that individuals who reported higher stress and stigma tended to report more emotional eating and had higher BF%. Stress partially explained the association between internalized weight stigma and emotional eating, and emotional eating partially explained the relationship between stress and BF% but did not significantly mediate the association between stigma and BF%. Greater stress and internalized weight stigma were associated with more emotional eating and higher BF%; however, emotional eating only partially explained the association between stress and BF%. Results highlight the importance of interventions targeting stress management skills, but additional research is needed to identify mechanisms that explain the association between stigma and BF%.

A soldier's return to duty after minimally invasive correction of complex congenital cardiovascular disease

We report a case of incidental detection of severe aortic coarctation, severe secundum atrial septal defect, and bicuspid aortic valve in an active-duty military service member. A single complex minimally invasive procedure successfully corrected his coarctation and atrial septal defect allowing this patient to continue military service.

Psychometric Properties of the Self-Injurious Thoughts and Behaviors Interview-Short Form Among U.S. Active Duty Military Service Members and Veterans.

We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans. Approximately 8% of participants who denied a history of suicidal ideation on the SITBI-SF reported suicidal ideation on a separate self-report questionnaire (i.e., discordant responders). Discordant responders reported significantly higher levels of PTSD symptoms than those who denied suicidal ideation on both response formats. Findings suggest that the SITBI-SF is a reliable and valid interview-based measure of suicide-related thoughts and behaviors for use with military service members and veterans. Suicide risk assessment might be optimized if the SITBI-SF interview is combined with a self-report measure of related constructs.

Stigma and Barriers in Health Care Among a Sample of Transgender and Gender-Diverse Active Duty Service Members.

Transgender and/or gender-diverse (TGD) persons are vulnerable to stigma and health care inequities; however, data are particularly limited among TGD active duty military service members despite ongoing changes to service policies. TGD-related stressors may impede access to and utilization of health care due to fear of potential discrimination and distress, thereby adversely impacting military readiness. We examined stigma and barriers in health care and associations with physical and mental health in an online sample of 177 active duty service members who self-identified as TGD. To assess associations between stigma and barriers in health care with mental and physical health, linear regressions were conducted adjusting for age, gender identity, race, and rank. Over half (65%) of the participants reported at least 1 instance of stigma and/or barrier in health care. Stigma and barriers to health care were significantly associated with greater self-reported depressive symptoms (β=0.20, P =0.03), anxiety (β=0.21, P =0.03), stress (β=0.30, P =0.001), and poorer overall mental health (β=-0.23, P =0.007), after adjusting for covariates. Nearly one-quarter of participants had not disclosed their gender identity to their primary care clinician. Findings suggested that stigma and barriers to affirming health care were prevalent among active duty service members identifying as TGD, specifically, difficulty accessing gender-affirming care and negative assumptions from clinicians. These experiences may adversely affect mental health and impede the quality of health care received by a population already vulnerable to health inequities. Given recent changes to military policy, efforts may be warranted to improve access to timely, affirming care and clinician training.

Discriminating Mild Traumatic Brain Injury and Posttraumatic Stress Disorder Using Latent Neuroimaging and Neuropsychological Profiles in Active-Duty Military Service Members.

Mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) commonly occur among military Service Members and Veterans and have heterogenous, but also overlapping symptom presentations, which often complicate the diagnoses of underlying impairments and development of effective treatment plans. Thus, we sought to examine whether the combination of whole brain gray matter (GM) and white matter (WM) structural measures with neuropsychological performance can aid in the classification of military personnel with mTBI and PTSD. Active-Duty US Service Members ( n = 156; 87.8% male) with a history of mTBI, PTSD, combined mTBI+PTSD, or orthopedic injury completed a neuropsychological battery and T1- and diffusion-weighted structural neuroimaging. Cortical, subcortical, ventricular, and WM volumes and whole brain fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) were calculated. Latent profile analyses were performed to determine how the GM and WM indicators, together with neuropsychological indicators, classified individuals. For both GM and WM, respectively, a 4-profile model was the best fit. The GM model identified greater ventricular volumes in Service Members with cognitive symptoms, including those with a diagnosis of mTBI, either alone or with PTSD. The WM model identified reduced FA and elevated RD in those with psychological symptoms, including those with PTSD or mTBI and comorbid PTSD. However, contrary to expectation, a global neural signature unique to those with comorbid mTBI and PTSD was not identified. The findings demonstrate that neuropsychological performance alone is more robust in differentiating Active-Duty Service Members with mTBI and PTSD, whereas global neuroimaging measures do not reliably differentiate between these groups.

Incidence rates of emotional, sexual, and physical abuse in active-duty military service members, 1997–2015

Sexual, emotional, and physical abuse are often underreported in the Military, and large-scale epidemiological research is limited. The current work examines the incidence rates of abuse across six demographic factors (age, gender, rank, marital status, race, and branch) using the Defense Medical Epidemiology Database (DMED) in active-duty U.S. military service members to establish a comparative cohort for future work in this area. Data were extracted from 1997 to 2015 and analyzed using a one-sample chi-square goodness-of-fit test. Women report emotional abuse over two times more than expected, physical abuse twice as much, and sexual abuse five times more than expected. Black service members were reported emotional abuse at rates 87% greater than anticipated based on base military proportions, reported double the amount of physical abuse than expected, and received sexual abuse diagnoses 35% more than expected. Paygrades E5-E9 had higher than expected emotional abuse rates, while married service members had higher than expected emotional and physical abuse rates. White, male, and higher rank service members reported lower than expected rates for any abuse type. The present study provides a strong foundation for further research and developing interventions aimed toward vulnerable populations in the U.S. military.

Abstract 20: Cancer incidence in the U.S. military: An updated analysis

Abstract Background: Active duty military service members and the general US population differ in several ways related to cancer occurrence. This study aimed to update and expand our previous study which compared incidence of six cancers between the U.S. military and general populations. Methods: Cancers included in this study were pathologically confirmed malignant lung, colorectal, testicular, prostate, cervical and breast tumors diagnosed 1990-2013. The study populations were men and women aged 20-59 in the US active duty military and the population in nine areas covered by the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) cancer registry program. Military data were from the Department of Defense’s Automated Central Tumor Registry (ACTUR) and Defense Manpower Data Center. Age adjusted rates in ACTUR and SEER and incidence rate ratios (IRR) and 95% confidence intervals (95% CI) comparing ACTUR to SEER were calculated. Comparisons were made by sex, race, and cancer stage. Results: Age adjusted incidence rates of colorectal cancer were significantly lower in ACTUR than SEER among White (IRR 0.78; 95% CI 0.72-0.84) and Black men (IRR 0.86; 95% CI 0.74-1.00), respectively. Lung cancer incidence was lower in ACTUR than SEER among White (IRR 0.55; 95% CI 0.49-0.62) and Black men (IRR 0.34; 95% CI 0.26-0.42) and White women (IRR 0.74; 95% CI 0.53-0.98). Whites in ACTUR had significantly lower incidence of testicular cancer (IRR 0.92; 95% CI 0.88-0.96). Lower incidence of cervical cancer in ACTUR was observed among both Whites (IRR 0.82; 95% CI 0.69-0.97) and Blacks (IRR 0.39; 95% CI 0.27-0.54). Incidence of prostate cancer was higher in ACTUR than SEER among both Whites (IRR 2.31; 95% CI 2.18-2.45) and Blacks (IRR 2.35; 95% CI 2.13-2.58). Results by tumor stage showed similar results between the ACTUR and SEER populations for regional and distant tumors, while no differences between the two were observed for localized tumors, except in the case of prostate cancer. Incidence of localized and regional prostate tumors was higher in ACTUR than SEER, while there was no significant difference in distant tumors. Conclusion: Active duty service members had lower age adjusted incidence rates of colorectal, lung, testicular, and cervical cancers, but higher rates of prostate cancer than the general US population. While these findings may result from the combined effects of many factors, the lower incidence in the military may be associated with healthier status of service members. In addition, universal health care for active duty military may lead to earlier diagnosis of some tumors, such as prostate cancer, in the military.

Pain Catastrophizing Predicts Opioid and Health-Care Utilization After Orthopaedic Surgery: A Secondary Analysis of Trial Participants with Spine and Lower-Extremity Disorders.

Most individuals undergoing elective surgery expect to discontinue opioid use after surgery, but many do not. Modifiable risk factors including psychosocial factors are associated with poor postsurgical outcomes. We wanted to know whether pain catastrophizing is specifically associated with postsurgical opioid and health-care use. This was a longitudinal cohort study of trial participants undergoing elective spine (lumbar or cervical) or lower-extremity (hip or knee osteoarthritis) surgery between 2015 and 2018. Primary and secondary outcomes were 12-month postsurgical days' supply of opioids and surgery-related health-care utilization, respectively. Self-reported and medical record data included presurgical Pain Catastrophizing Scale (PCS) scores, surgical success expectations, opioid use, and pain interference duration. Complete outcomes were analyzed for 240 participants with a median age of 42 years (34% were female, and 56% were active-duty military service members). In the multivariable generalized additive model, greater presurgical days' supply of opioids (F = 17.23, p < 0.001), higher pain catastrophizing (F = 1.89, p = 0.004), spine versus lower-extremity surgery (coefficient estimate = 1.66 [95% confidence interval (CI), 0.50 to 2.82]; p = 0.005), and female relative to male sex (coefficient estimate = -1.25 [95% CI, -2.38 to -0.12]; p = 0.03) were associated with greater 12-month postsurgical days' supply of opioids. Presurgical opioid days' supply (chi-square = 111.95; p < 0.001), pain catastrophizing (chi-square = 96.06; p < 0.001), and lower extremity surgery (coefficient estimate = -0.17 [95% CI, -0.24 to -0.11]; p < 0.001), in addition to age (chi-square = 344.60; p < 0.001), expected recovery after surgery (chi-square = 54.44; p < 0.001), active-duty status (coefficient estimate = 0.58 [95% CI, 0.49 to 0.67]; p < 0.001), and pain interference duration (chi-square = 43.47; p < 0.001) were associated with greater health-care utilization. Greater presurgical days' supply of opioids and pain catastrophizing accounted for greater postsurgical days' supply of opioids and health-care utilization. Consideration of several modifiable factors provides an opportunity to improve postsurgical outcomes. Prognostic Level III .

Massed Cognitive Processing Therapy in Active-Duty Military: A Case Series

Despite consistent evidence that Cognitive Processing Therapy (CPT) is an efficacious treatment for posttraumatic stress disorder (PTSD), the effects among active-duty service members and veterans have been smaller than for civilians. Modifications to standard delivery may be needed to increase treatment engagement and completion, which could improve outcomes in this population. Delivering CPT in a massed format may reduce barriers to care and enable more rapid symptom reduction, yet clinicians and patients may have concerns about the tolerability and practicality of such interventions. This case series describes a course of CPT delivered in 5 days in a mixed group and individual format among 4 active-duty military service members as part of a larger randomized clinical trial. Although the pattern of symptom change differed between patients, most demonstrated clinically significant reductions in PTSD and depression symptoms during the 5-day treatment. Patients reported that the pace was tolerable and that the mixed group and individual format was beneficial. Although further research is needed to understand the longer-term outcomes of massed CPT, this therapy format has important implications for the future delivery of treatments for PTSD.

Evaluation of an Opioid Overdose Composite Risk Score Cutoff in Active Duty Military Service Members

To evaluate the current cutoff score and a recalibrated adaptation of the Veterans Health Administration (VHA) Risk Index for Serious Prescription Opioid-Induced Respiratory Depression or Overdose (RIOSORD) in active duty service members. Retrospective case-control. Military Health System. Active duty service members dispensed ≥ 1 opioid prescription between January 1, 2018, and December 31, 2019. Service members with a documented opioid overdose were matched 1:10 to controls. An active duty-specific (AD) RIOSORD was constructed using the VHA RIOSORD components. Analyses examined the risk stratification and predictive characteristics of two RIOSORD versions (VHA and AD). Cases (n = 95) were matched with 950 controls. Only 6 of the original 17 elements were retained in the AD RIOSORD. Long-acting or extended-release opioid prescriptions, antidepressant prescriptions, hospitalization, and emergency department visits were associated with overdose events. The VHA RIOSORD had fair performance (C-statistic 0.77, 95% CI 0.75, 0.79), while the AD RIOSORD did not demonstrate statistically significant performance improvement (C-statistic 0.78, 95% CI, 0.77, 0.80). The DoD selected cut point (VHA RIOSORD &gt; 32) only identified 22 of 95 ORD outcomes (Sensitivity 0.23), while an AD-specific cut point (AD RIOSORD &gt; 16) correctly identified 53 of 95 adverse events (Sensitivity 0.56). Results highlight the need to continually recalibrate predictive models and to consider multiple measures of performance. Although both models had similar overall performance with respect to the C-statistic, an AD-specific index threshold improves sensitivity. The calibrated AD RIOSORD does not represent an end-state, but a bridge to a future model developed on a wider range of patient variables, taking into consideration features that capture both care received, and care that was not received.

Prevalence of caffeine consumers, daily caffeine consumption, and factors associated with caffeine use among active duty United States military personnel

BackgroundAlthough representative data on caffeine intake in Americans are available, these data do not include US service members (SMs). The few previous investigations in military personnel largely involve convenience samples. This cross-sectional study examined prevalence of caffeine consumers, daily caffeine consumption, and factors associated with caffeine use among United States active duty military service members (SMs).MethodsA stratified random sample of SMs were asked to complete an on-line questionnaire on their personal characteristics and consumption of caffeinated products (exclusive of dietary supplements). Eighteen percent (n = 26,680) of successfully contacted SMs (n = 146,365) completed the questionnaire.ResultsOverall, 87% reported consuming caffeinated products ≥1 time/week. Mean ± standard error per-capita consumption (all participants) was 218 ± 2 and 167 ± 3 mg/day for men and women, respectively. Caffeine consumers ingested 243 ± 2 mg/day (251 ± 2 mg/day men, 195 ± 3 mg/day women). On a body-weight basis, men and women consumed respectively similar caffeine amounts (2.93 vs 2.85 mg/day/kg; p = 0.12). Among individual caffeinated products, coffee had the highest use (68%), followed by sodas (42%), teas (29%), energy drinks (29%) and gums/candy/medications (4%). In multivariable logistic regression, characteristics independently associated with caffeine use (≥1 time/week) included female gender, older age, white race/ethnicity, higher body mass index, tobacco use or former use, greater alcohol intake, and higher enlisted or officer rank.ConclusionCompared to National Health and Nutrition Examination Survey data, daily caffeine consumption (mg/day) by SMs was higher, perhaps reflecting higher mental and physical occupational demands on SMs.

Surgical treatment of anterior shoulder instability with glenoid bone loss with the Latarjet procedure in active-duty military service members.

The arthroscopic Bankart repair in the setting of glenoid bone loss has high rates of failure. In patients with anterior glenoid bone loss, the Latarjet provides glenohumeral stability through restoration of the glenoid bone, the conjoint tendon acting as a sling on the subscapularis, and anterior capsulolabral repair. Active-duty military personnel are at high risk for glenohumeral instability and have been equated to the contact athlete; most are young, male, and engage in contact sports. The purpose of this study is to assess the return to full-duty rates in active-duty military personnel following the Latarjet for anterior glenohumeral instability with glenoid bone loss. A retrospective review of all glenohumeral instability procedures were reviewed at a tertiary training hospital from June 2014 to June 2019. The patient population consisted of active-duty military personnel with glenoid bone loss and anterior glenohumeral instability, who were treated with a Latarjet. The primary outcome was return to full-duty status. There were 50 patients identified for the study. Four patients were lost to follow-up, leaving 46 of 50 patients (92.0%) eligible for this study. The average age at the time of the index procedure was 23.1 years. The average percentage bone loss was 18.4%. Forty-one patients (89.1%) were able to return to full-duty status. Four patients (8.7%) sustained a recurrent dislocation following the Latarjet; all 4 dislocations occurred during a combat deployment. Four patients (8.7%) reported episodes of subluxation without dislocation. Forty-one patients (89.1%) reported that their shoulders felt stable, and we found an average return to full duty at 5.3 months CONCLUSION: In our active-duty military cohort, we found an 8.7% rate of recurrent instability after a Latarjet procedure, and 41 patients (89.1%) were able to return to full-duty status. In conclusion, the Latarjet procedure in the active-duty military population with anterior glenoid bone loss resulted in a high rate of return to duty, excellent functional outcomes, low rate of recurrent instability, and a low overall complication rate.
