Abstract
BACKGROUND:
The incidence of eye injuries in military service members is high in the combat setting. This is the first study that identifies the primary reason for poor visual acuity (worse than 20/200).
METHODS:
This is a retrospective, noncomparative, interventional case series analyzing US Operation Iraqi and Enduring Freedom members who were evacuated from the theater of operations to Walter Reed Army Medical Center from 2001 through 2011. Primary outcome measures were the length of follow-up, globe survival, and anatomic causes of blindness. Secondary outcome measures included surgical procedures performed, use of eye protection, nonocular injuries, incidence of traumatic brain injury, source of injury, visual outcomes, and predictability of Ocular Trauma Score (OTS) on visual outcome. Univariate analysis was performed using χ and Fisher's exact test. A p < 0.01 was considered significant because of the multiple hypotheses tested.
RESULTS:
There were 265 eyes of 239 patients who had final best-corrected visual acuity of worse than 20/200. The average age was 27.4 years (range, 19-53 years). Of the patients, 97.5% were male, and 28.9% had documented use of eye protection. The average follow-up was 350.19 days (range, 3-2,421 days). There were 128 right-eye and 133 left-eye injuries, with a total of 26 bilateral injuries. There were 206 open-globe and 56 closed-globe injuries, which were further subdivided into zones. Open-globe Zone III injuries (81.6%) were the number one cause of blindness, and most injuries were caused by improvised explosive devices (64.2%). Enucleation was the most common surgery performed (40.6%) and therefore the leading cause of blindness, followed by a multifactorial cause and direct traumatic optic neuropathy.
CONCLUSION:
Ocular trauma is common among combat injuries. Close to a third of service members that experience an ocular trauma become legally blind. Further research is needed to focus on strategies to prevent injury and improve visual outcomes.

Abstract
Background Studies with members of the armed forces have found a gap between reports of mental health symptoms and treatment-seeking. Aims To assess the impact of attitudes on treatment-seeking behaviours in soldiers returning from a combat deployment. Method A sample of 529 US soldiers were surveyed 4 months (time 1) and 12 months (time 2) post-deployment. Mental health symptoms and treatment-seeking attitudes were assessed at time 1; reported mental healthcare visits were assessed at time 2.Results Factor analysis of the total time 1 sample revealed four attitude factors: professional concerns, practical barriers, preference for self-management and positive attitudes about treatment. For the subset of 160 soldiers reporting a mental health problem at time 1, and controlling for mental health symptom severity, self-management inversely predicted treatment-seeking; positive attitudes were positively related. Conclusions Results demonstrate the importance of broadening the conceptualization of barriers and facilitators of mental healthcare beyond stigma. Techniques and delivery models emphasising self-care may help increase soldiers' interest in using mental health services.

Abstract
The introduction and rapid spread of chikungunya virus (CHIKV) into the Western Hemisphere after December 2013 pose a potentially significant risk to Department of Defense (DoD) personnel, operations, and the military healthcare system. This report describes the DoD experience with CHIKV between January 2014 and February 2015 using case reports in the Defense Medical Surveillance System's (DMSS) Reportable Medical Events database and the Navy and Marine Corps Public Health Center's laboratory test results database. Case finding identified 157 confirmed cases; of these, 118 (75.2%) were either active or reserve component service members and 39 (24.8%) were other beneficiaries. Exposure locations were known for 117 (74.5%) of all cases, and of these, 113 (96.6%) reported likely exposures in the Western Hemisphere; 85 (75.2%) of those cases occurred in Puerto Rico. Although historical data on CHIKV in DoD populations are scant, introduction of CHIKV into the Western Hemisphere with ongoing transmission appears to have resulted in a significant increase in the number of cases among DoD healthcare beneficiary populations.

Study
Abstract
BACKGROUND:
Attendance by military medical personnel (MMP) at scientific meetings (SMs) of civilian associations has been centrally managed since 2012. We aimed to document the importance of civilian-military interaction to and the impact of this change on combat casualty care (CCC) research.
METHODS:
(1) We identified 25 clinically significant CCC articles published by MMP between 2005 and 2014; we determined whether these articles were preceded by presentation by MMP at an SM. (2) We examined the changing civilian-military mix of publications on "damage control resuscitation" (DCR). (3) We analyzed the number of presentations by MMP each year at the American Association for the Surgery of Trauma. (4) We reviewed whether past presidents of the AAST (for 1992-2014) had military experience.
RESULTS:
(1) Ninety-two percent of the CCC articles were previously presented at an SM; 66% were presented at civilian association venues such as AAST. (2) DCR was first described in 2006; the civilian-military mix of publications rose steadily from 0 in 2006 to 80% in 2014. (3) The number of MMP oral presentations at AAST peaked during 2005 to 2007 and has declined to one to two per year since 2012. (4) Thirty-three percent of recent AAST presidents had military experience, versus 100% for the previous era.
CONCLUSION:
Recent conflicts led to intense civilian-military collaboration in CCC research and to the spread of ideas such as DCR from military to civilian care. However, long-term trends (e.g., declining rates of military service nationally) place such collaboration at risk. Vigorous efforts to foster the vital civilian-military link in CCC are needed.

Abstract
The Department of Defense Serum Repository (DoDSR) contains a growing archive of sera from service members collected to perform medical surveillance, clinical diagnosis, and epidemiologic studies to identify, prevent, and control diseases associated with military service. The specimens are a mandatory collection under DoD and U.S. regulations and do not include informed consent for uses beyond force health protection. Any use of the specimens for research requires deidentification of the samples and must be approved by Institutional Review Boards. However, as expansion of the DoDSR is contemplated, ethical considerations of sample collection, storage, and use must be carefully reconsidered. Other similar programs for research use of specimens collected for public health purpose are also undergoing similar reviews. It is recommended that at a minimum, service members are informed of the potential storage and use of their specimens and are allowed to opt out of additional use, or a broad informed consent is provided. The DoDSR provides a tremendous resource to the DoD and global health community, and to ensure its continued existence and improvement, the DoD must stay consistent with all principles of research ethics.

Abstract
BACKGROUND:
Lung cancer is the leading cause of cancer-related death in the United States (US) Military and worldwide, with non-small cell lung cancer (NSCLC) accounting for 87 % of cases.
OBJECTIVES:
Using a US military cohort who receives equal and open access to healthcare, we sought to examine demographic, clinical features and outcomes with NSCLC.
DESIGN AND PARTICIPANTS:
We conducted a retrospective cohort analysis of 4,751 patients, aged ≥ 18 years and diagnosed with a first primary NSCLC between 1 January 2003 and 31 December 2013 in the US Department of Defense (DoD) cancer registry.
MAIN MEASURES:
Differences by patient and disease characteristics were compared using Chi-square and t-test. Kaplan Meier curves and Cox proportional hazards regression assessed overall survival.
RESULTS:
The mean age at diagnosis was 66 years, 64 % were male, 72 % were Caucasian, 41 % were diagnosed at early stage, 77 % received treatment and 82 % had a history of tobacco use. Mean age at diagnosis was highest among Caucasians (67 years) and lowest among African Americans (AA; 62 years). Asian/Pacific Islanders (PI) were more likely to be female (p < 0.0001), have adenocarcinoma histology (p = 0.0003) and less likely to have a history of tobacco use (p < 0.0001) compared to other racial/ethnic groups. In multivariable survival analysis, older age, male gender, increasing stage, not receiving treatment, and tobacco history were associated with higher mortality risk. Untreated patients exhibited a 39 % higher mortality risk compared to treated patients (HR = 1.39; 95%CI = 1.23-1.57). Compared to Caucasian patients, Asian/PIs demonstrated a 20 % lower risk of death (HR = 0.80; 95%CI = 0.66-0.96). There was no difference in mortality risk between AAs and Hispanics compared to Caucasians.
CONCLUSION:
The lack of significant outcome disparity between AAs and Caucasians and the earlier stage at diagnosis than usually seen in civilian populations suggest that equal access to healthcare may play a role in early detection and survival.

Abstract
Long-term antimalarial chemoprophylaxis is currently used by deployed U.S. military personnel. Previous small, short-term efficacy studies have shown variable rates of side effects among patients taking various forms of chemoprophylaxis, though reliable safety and tolerability data on long-term use are limited. We conducted a survey of troops returning to Fort Drum, NY following a 12-month deployment to Operation Enduring Freedom, Afghanistan from 2006 to 2007. Of the 2,351 respondents, 95% reported taking at least one form of prophylaxis during their deployment, and 90% were deployed for > 10 months. Compliance with daily doxycycline was poor (60%) compared with 80% with weekly mefloquine (MQ). Adverse events (AEs) were reported by approximately 30% with both MQ and doxycycline, with 10% discontinuing doxycycline compared with 4% of MQ users. Only 6% and 31% of soldiers reported use of bed nets and skin repellents, respectively. Compliance with long-term malaria prophylaxis was poor, and there were substantial tolerability issues based on these anonymous survey results, though fewer with MQ than doxycycline. Given few long-term antimalarial chemoprophylaxis options, there is an unmet medical need for new antimalarials safe for long-term use.

Abstract
Recent armed conflicts and the expanded reach of international terror groups has resulted in an increased incidence of blast-related injuries in both military and civilian populations. Mass-casualty incidents may require both on-scene and in-hospital triage to maximize survival rates and conserve limited resources. Initial evaluation should focus on the identification and control of potentially life-threatening conditions, especially life-threatening hemorrhage. Early operative priorities for musculoskeletal injuries focus on the principles of damage-control orthopaedics, with early and aggressive debridement of soft-tissue wounds, vascular shunting or grafting to restore limb perfusion, and long-bone fracture stabilization via external fixation. Special considerations such as patient transport, infection control and prevention, and amputation management are also discussed. All orthopedic surgeons, regardless of practice setting, should be familiar with the basic principles of evaluation, resuscitation, and initial management of explosive blast injuries.

Abstract
Divergent findings from previous research examining gender differences in the development of posttraumatic stress disorder (PTSD) among US military members deployed to the operations in Iraq or Afghanistan (recent operations) prompted this study utilizing a matching approach to examine whether risk for new-onset PTSD and PTSD severity scores differed by gender. US military members from the Millennium Cohort Study deployed in support of the recent operations were followed for approximately 7 years from baseline through 2 follow-up periods between 2001 and 2008. Propensity score matching was used to match 1 male to each female using demographic, military, and behavioral factors including baseline sexual assault. Analyses were stratified by combat experience defined as reporting at least one of five exposures during follow-up. Outcome measures included a positive screen for PTSD and severity scores measured by the PTSD Patient Checklist-Civilian Version. Discrete-time survival analysis quantified the association between gender and incident PTSD. Among 4684 matched subjects (2342 women and men), 6.7% of women and 6.1% of men developed PTSD during follow-up. Results showed no significant gender differences for the likelihood of developing PTSD or for PTSD severity scores among women and men who reported combat experience and among those who did not. This study is the first of its kind to match a large population of male and female service members on important baseline characteristics including sexual assault. Findings suggest that while combat deployed personnel develop PTSD, women do not have a significantly different risk for developing PTSD than men after experiencing combat.

Abstract
OBJECTIVE:
Limited data suggest that the children of U.S. service members may be at increased risk for disordered-eating. To date, no study has directly compared adolescent military-dependents to their civilian peers along measures of eating pathology and associated correlates. We, therefore, compared overweight and obese adolescent female military-dependents to their civilian counterparts along measures of eating-related pathology and psychosocial functioning.
METHOD:
Adolescent females with a BMI between the 85th and 97th percentiles and who reported loss-of-control eating completed interview and questionnaire assessments of eating-related and general psychopathology.
RESULTS:
Twenty-three military-dependents and 105 civilians participated. Controlling for age, race, and BMI-z, military-dependents reported significantly more binge episodes per month (p < 0.01), as well as greater eating-concern, shape-concern, and weight-concern (p's < 0.01) than civilians. Military-dependents also reported more severe depression (p < 0.05).
DISCUSSION:
Adolescent female military-dependents may be particularly vulnerable to disordered-eating compared with civilian peers. This potential vulnerability should be considered when assessing military-dependents.

Abstract
The extent to which multiple past concussions are associated with lingering symptoms or mental health problems in military service members is not well understood. The purpose of this study was to examine the association between lifetime concussion history, cognitive functioning, general health, and psychological health in a large sample of fit-for-duty U.S. Army soldiers preparing for deployment. Data on 458 active-duty soldiers were collected and analyzed. A computerized cognitive screening battery (CNS-Vital Signs(®)) was used to assess complex attention (CA), reaction time (RT), processing speed (PS), cognitive flexibility (CF), and memory. Health questionnaires included the Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Military Version (PCL-M), Zung Depression and Anxiety Scales (ZDS; ZAS), Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the Alcohol Use and Dependency Identification Test (AUDIT). Soldiers with a history of multiple concussions (i.e., three or more concussions) had significantly greater post-concussive symptom scores compared with those with zero (d=1.83, large effect), one (d=0.64, medium effect), and two (d=0.64, medium effect) prior concussions. Although the group with three or more concussions also reported more traumatic stress symptoms, the results revealed that traumatic stress was a mediator between concussions and post-concussive symptom severity. There were no significant differences on neurocognitive testing between the number of concussions. These results add to the accumulating evidence suggesting that most individuals recover from one or two prior concussions, but there is a greater risk for ongoing symptoms if one exceeds this number of injuries.

Abstract
Seventy-one deployed U.S. Army soldiers who presented for concussion care due to either blast or blunt mechanisms within 72 h of injury were assessed using the Military Acute Concussion Evaluation, the Automated Neuropsychological Assessment Metrics (ANAM), traditional neuropsychological tests, and health status questionnaires. Follow-up ANAM testing was performed 10 d after initial testing (±5 d). Twenty-one soldiers were excluded: two for poor effort and 19 who had combined blast/blunt injuries. Of the remaining 50 male participants, 34 had blast injuries and 16 had blunt injuries. There were no statistically significant differences between blast injury and blunt injury participants in demographic, physical, or psychological health factors, concussive symptoms, or automated and traditional neurocognitive testing scores within 72 h post-injury. In addition, follow-up ANAM scores up to 15 d post-injury were not significantly different (available on 21 blast-injured and 13 blunt-injured subjects). Pre-injury baseline ANAM scores were compared where available, and revealed no statistically significant differences between 22 blast injury and eight blunt injury participants. These findings suggest there are no significant differences between mechanisms of injury during both the acute and subacute periods in neurobehavioral concussion sequelae while deployed in a combat environment. The current study supports the use of sports/mechanical concussion models for early concussion management in the deployed setting and exploration of variability in potential long-term outcomes.

Abstract
Can social resilience be trained? We report results of a double-dissociative randomized controlled study in which 48 Army platoons were randomly assigned to social resilience training (intervention condition) or cultural awareness training (active control group). The same surveys were administered to all platoons at baseline and after the completion of training to determine the short-term training effects, generalization effects beyond training, and possible adverse effects. Multilevel modeling analyses indicated that social resilience, compared with cultural awareness, training produced small but significant improvements in social cognition (e.g., increased empathy, perspective taking, & military hardiness) and decreased loneliness, but no evidence was found for social resilience training to generalize beyond these training foci nor to have adverse effects. Moreover, as predicted, cultural awareness, compared with social resilience, training produced increases in knowledge about and decreases in prejudice toward Afghans. Additional research is warranted to determine the long-term durability, safety, and generalizability of social resilience training.
