Abstract
BACKGROUND:
Recent neuroimaging work suggests that increased amygdala responses to emotional stimuli and dysfunction within regions mediating top down attentional control (dorsomedial frontal, lateral frontal and parietal cortices) may be associated with the emergence of anxiety disorders, including posttraumatic stress disorder (PTSD). This report examines amygdala responsiveness to emotional stimuli and the recruitment of top down attention systems as a function of task demands in a population of U.S. military service members who had recently returned from combat deployment in Afghanistan/Iraq. Given current interest in dimensional aspects of pathophysiology, it is worthwhile examining patients who, while not meeting full PTSD criteria, show clinically significant functional impairment.
METHODS:
Fifty-seven participants with sub-threshold levels of PTSD symptoms completed the affective Stroop task while undergoing fMRI. Participants with PTSD or depression at baseline were excluded.
RESULTS:
Greater PTSD symptom severity scores were associated with increased amygdala activation to emotional, particularly positive, stimuli relative to neutral stimuli. Furthermore, greater PTSD symptom severity was associated with increased superior/middle frontal cortex response during task conditions relative to passive viewing conditions. In addition, greater PTSD symptom severity scores were associated with: (i) increased activation in the dorsolateral prefrontal, lateral frontal, inferior parietal cortices and dorsomedial frontal cortex/dorsal anterior cingulate cortex (dmFC/dACC) in response to emotional relative to neutral stimuli; and (ii) increased functional connectivity during emotional trials, particularly positive trials, relative to neutral trials between the right amygdala and dmFC/dACC, left caudate/anterior insula cortex, right lentiform nucleus/caudate, bilateral inferior parietal cortex and left middle temporal cortex.
CONCLUSIONS:
We suggest that these data may reflect two phenomena associated with increased PTSD symptomatology in combat-exposed, but PTSD negative, armed services members. First, these data indicate increased emotional responsiveness by: (i) the positive relationship between PTSD symptom severity and amygdala responsiveness to emotional relative to neutral stimuli; (ii) greater BOLD response as a function of PTSD symptom severity in regions implicated in emotion (striatum) and representation (occipital and temporal cortices) during emotional relative to neutral conditions; and (iii) increased connectivity between the amygdala and regions implicated in emotion (insula/caudate) and representation (middle temporal cortex) as a function of PTSD symptom severity during emotional relative to neutral trials. Second, these data indicate a greater need for the recruitment of regions implicated in top down attention as indicated by (i) greater BOLD response in superior/middle frontal gyrus as a function of PTSD symptom severity in task relative to view conditions; (ii) greater BOLD response in dmFC/dACC, lateral frontal and inferior parietal cortices as a function of PTSD symptom severity in emotional relative to neutral conditions and (iii) greater functional connectivity between the amygdala and inferior parietal cortex as a function of PTSD symptom severity during emotional relative to neutral conditions.

Abstract
BACKGROUND: The prevalence of suicide among U.S. Army soldiers has risen dramatically in recent years. Prior studies suggest that most soldiers with suicidal behaviors (i.e., ideation, plans, and attempts) had first onsets prior to enlistment. However, those data are based on retrospective self-reports of soldiers later in their Army careers. Unbiased examination of this issue requires investigation of suicidality among new soldiers.
METHOD: The New Soldier Study (NSS) of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) used fully structured self-administered measures to estimate preenlistment histories of suicide ideation, plans, and attempts among new soldiers reporting for Basic Combat Training in 2011-2012. Survival models examined sociodemographic correlates of each suicidal outcome.
RESULTS: Lifetime prevalence estimates of preenlistment suicide ideation, plans, and attempts were 14.1, 2.3, and 1.9%, respectively. Most reported onsets of suicide plans and attempts (73.3-81.5%) occurred within the first year after onset of ideation. Odds of these lifetime suicidal behaviors among new soldiers were positively, but weakly associated with being female, unmarried, religion other than Protestant or Catholic, and a race/ethnicity other than non-Hispanic White, non-Hispanic Black, or Hispanic.
CONCLUSIONS: Lifetime prevalence estimates of suicidal behaviors among new soldiers are consistent with retrospective reports of preenlistment prevalence obtained from soldiers later in their Army careers. Given that prior suicidal behaviors are among the strongest predictors of later suicides, consideration should be given to developing methods of obtaining valid reports of preenlistment suicidality from new soldiers to facilitate targeting of preventive interventions.

Abstract
Traumatic brain injuries (TBI) sustained in combat frequently co-occur with significant bodily injuries. Intuitively, more extensive bodily injuries might be associated with increased symptom reporting. In 2012, however, French et al. demonstrated an inverse relation between bodily injury severity and symptom reporting. This study expands on that work by examining the influence of location and severity of bodily injuries on symptom reporting after mild TBI. Participants were 579 US military service members who sustained an uncomplicated mild TBI with concurrent bodily injuries and who were evaluated at two military medical centers. Bodily injury severity was quantified using a modified Injury Severity Score (ISSmod). Participants completed the Neurobehavioral Symptom Inventory (NSI) and the Posttraumatic Stress Disorder Checklist (PCL-C), on average, 2.5 months post-injury. There was a significant negative association between ISSmod scores and NSI (r=-0.267, p<0.001) and PCL-C (r=-0.273, p<0.001) total scores. Using linear regression to examine the relation between symptom reporting and injury severity across the six ISS body regions, three body regions were significant predictors of the NSI total score (face; p<0.001; abdomen; p=0.003; extremities; p<0.001) and accounted for 9.3% of the variance (p<0.001). For the PCL-C, two body regions were significant predictors of the PCL-C total score (face; p<0.001; extremities; p<0.001) and accounted for 10.5% of the variance. There was an inverse relation between bodily injury severity and symptom reporting in this sample. Hypothesized explanations include underreporting of symptoms, increased peer support, disruption of fear conditioning because of acute morphine use, or delayed expression of symptoms.

Abstract
The need to understand the impact of war on military families has never been greater than during the past decade, with more than three million military spouses and children affected by deployments to Operations Iraqi Freedom and Enduring Freedom. Understanding the impact of the recent conflicts on families is a national priority, however, most studies have examined spouses and children individually, rather than concurrently as families. The Department of Defense (DoD) has recently initiated the largest study of military families in US military history (the Millennium Cohort Family Study), which includes dyads of military service members and their spouses (n > 10,000). This study includes US military families across the globe with planned follow-up for 21+ years to evaluate the impact of military experiences on families, including both during and after military service time. This review provides a comprehensive description of this landmark study including details on the research objectives, methodology, survey instrument, ancillary data sets, and analytic plans. The Millennium Cohort Family Study offers a unique opportunity to define the challenges that military families experience, and to advance the understanding of protective and vulnerability factors for designing training and treatment programs that will benefit military families today and into the future.

Abstract
BACKGROUND:
War-related trauma, posttraumatic stress disorder (PTSD), depression and suicide are common in US military members. Often, those affected do not seek treatment due to stigma and barriers to care. When care is sought, it often fails to meet quality standards. A randomized trial is assessing whether collaborative primary care improves quality and outcomes of PTSD and depression care in the US military health system.
OBJECTIVE:
Describe the design and sample for a randomized effectiveness trial of collaborative care for PTSD and depression in military members attending primary care.
METHODS:
The STEPS-UP Trial (Stepped Enhancement of PTSD Services Using Primary Care) is a 6 installation (18 clinic) randomized effectiveness trial in the US military health system. Study rationale, design, enrollment and sample characteristics are summarized. Findings Military members attending primary care were referred to care management with suspected PTSD, depression or both were recruited for the trial (2,592) and 1,041 gave permission to contact for research participation. Of those, 666 (64%) met eligibility criteria, completed baseline assessments, and were randomized to 12months of usual collaborative primary care versus STEPS-UP collaborative care. Implementation was locally managed for usual collaborative care and centrally managed for STEPS-UP. Research reassessments occurred at 3-, 6-, and 12-months. Baseline characteristics were similar across the two intervention groups.
CONCLUSIONS:
STEPS-UP will be the first large scale randomized effectiveness trial completed in the US military health system, assessing how an implementation model affects collaborative care impact on mental health outcomes. It promises lessons for health system change.

Abstract
OBJECTIVES: This study establishes rates of use/abuse of Schedule II-IV prescription medications in U.S. active duty military personnel, and characterizes correlates of such use/abuse.
METHODS: All active duty personnel serving for 12 months during fiscal year 2010 were included. Data were obtained from medical and pharmacy claims and drug screening results. Logistic regression models were used to examine predictors of drug use, along with bivariate analyses to compare abuse of prescribed and illegal drugs.
RESULTS: Nearly one-third of active duty service members received at least one prescription for opioids, central nervous system depressants, or stimulants, with 26.4% having received at least one prescription for opioids. About 0.7%, 1.4%, and 0.6% of the total force received >90-day prescriptions for opioids, central nervous system depressants, or stimulants, respectively. Battlefield injury, receipt of psychotropic medications, and substance abuse adverse events were predictive of >90-day supply of opioids. About 0.7% of the total force had documented known drug abuse for prescribed drugs compared to 0.4% for illegal drug abuse.
CONCLUSIONS: We recommend systematic monitoring of prescriptions for controlled substances which may carry serious consequences, evaluation of the impact of controlled substances on military readiness, and examination of the rationale for prescribing controlled drugs.

Abstract
BACKGROUND:
Ratios of women graduating from the only US military medical school and entering surgical internships were reviewed and compared with national trends.
METHODS:
Data were obtained from the Uniformed Services University of the Health Sciences graduation announcements from 2002 to 2012.
RESULTS:
There were 1,771 graduates from 2002 to 2012, with 508 female (29%) and 1,263 male (71%) graduates. Female graduates increased over time (21% to 39%; P = .014). Female general surgery interns increased from 3.9% to 39% (P = .025). Female overall surgical subspecialty interns increased from 20% in 2002 to 36% in 2012 (P = .046). Women were represented well in obstetrics (57%), urology (44%), and otolaryngology (31%), but not in neurosurgery, orthopedics, and ophthalmology (0% to 20%).
CONCLUSIONS:
The sex disparity between military and civilian medical students occurs before entry. Once in medical school, women are just as likely to enter general surgery or surgical subspecialty as their male counterparts. Increased ratio of women in the class is unlikely to lead to a shortfall except in specific subspecialties.

Abstract
Explosive devices have been the most frequent cause of traumatic brain injury (TBI) among deployed contemporary U.S. service members. The purpose of this study was to examine the influence of previous cumulative blast exposures (that did or did not result in TBI) on later post-concussion and post-traumatic symptom reporting after sustaining a mild TBI (MTBI). Participants were 573 service members who sustained MTBI divided into four groups by number of blast exposures (1, 2, 3, and 4-10) and a nonblast control group. Post-concussion symptoms were measured using the Neurobehavioral Symptom Inventory (NSI) and post-traumatic stress disorder (PTSD) symptoms using the Post-traumatic Checklist-Civilian version (PCL-C). Results show groups significantly differed on total NSI scores (p<0.001), where symptom endorsement increased as number of reported blast exposures increased. Total NSI scores were significantly higher for the 3- and 4-10 blast groups compared with the 1- and 2-blast groups with effect sizes ranging from small to moderate (d=0.31 to 0.63). After controlling for PTSD symptoms using the PCL-C total score, NSI total score differences remained between the 4-10-blast group and the 1- and 2-blast groups, but were less pronounced (d=0.35 and d=0.24, respectively). Analyses of NSI subscale scores using PCL-C scores as a covariate revealed significant between-blast group differences on cognitive, sensory, and somatic, but not affective symptoms. Regression analyses revealed that cumulative blast exposures accounted for a small but significant amount of the variance in total NSI scores (4.8%; p=0.009) and total PCL-C scores (2.3%; p<0.001). Among service members exposed to blast, post-concussion symptom reporting increased as a function of cumulative blast exposures. Future research will need to determine the relationship between cumulative blast exposures, symptom reporting, and neuropathological changes

Abstract
Use of energy drinks and energy shots among military personnel is controversial. High amounts of caffeine (the primary active ingredient in these products) may impact performance of military duties. The impact of caffeine overconsumption and potential subsequent side effects that might be experienced by service members with unique roles and responsibilities is a concern. Reported here are the prevalence of use, reasons for use, and side effects associated with consumption of energy drinks and energy shots among several populations of active duty personnel in the US military. A snowball survey was sent to over 10,000 active duty personnel. A total of 586 (∼6% response rate) individuals completed a 30-item electronic survey. Over half of respondents (53%) reported consuming an energy drink at least once in the past 30 days. One in five (19%) reported energy shot consumption in the prior 30 days. One in five (19%) also reported consuming an energy drink in combination with an alcoholic beverage. Age and gender were significantly associated with energy drink consumption. Young male respondents (18-29 years) reported the highest use of both energy drinks and energy shots. Among those reporting energy drink and energy shot use, the most common reasons for consumption were to improve mental alertness (61%) and to improve mental (29%) and physical (20%) endurance. Nearly two-thirds (65%) of users self-reported at least one side effect. The most commonly reported side effects included increased pulse rate/palpitations, restlessness, and difficulty sleeping. Use of energy products among military personnel is common and has the potential to impact warrior health and military readiness.

Abstract
The aim of this study was to determine optimally efficient cutoff scores on the Posttraumatic Stress Disorder Checklist (PCL) for identifying full posttraumatic stress disorder (PTSD) and partial PTSD (P-PTSD) in active-duty Marines and Sailors. Participants were 1,016 Marines and Sailors who were administered the PCL and Clinician-Administered PTSD Scale (CAPS) 3 months after returning from Operations Iraqi and Enduring Freedom. PCL cutoffs were tested against three CAPS-based classifications: full PTSD, stringent P-PTSD, and lenient P-PTSD. A PCL score of 39 was found to be optimally efficient for identifying full PTSD. Scores of 38 and 33 were found to be optimally efficient for identifying stringent and lenient P-PTSD, respectively. Findings suggest that the PCL cutoff that is optimally efficient for detecting PTSD in active-duty Marines and Sailors is substantially lower than the score of 50 commonly used by researchers. In addition, findings provide scores useful for identifying P-PTSD in returning service members.

Abstract
Providing medical care to members of the military and their families remains a societal duty carried out not only by military physicians but also, and in large part, by civilian providers. As many military families are geographically dispersed, it is probable that all physicians at some point in their training or careers will care for this unique patient population. Understanding the military culture can help physicians provide the best care possible to our military families, and inclusion of military cultural competency curricula in all medical schools is a first step in advancing this understanding. The authors review the knowledge, skills, and attitudes that all health professionals should acquire to be able to care for those who serve and offer recommendations for developing these among all students and trainees.

Abstract
OBJECTIVE: We compared prevalence, health care utilization, and costs over time for nonelderly adults diagnosed with fibromyalgia syndrome (FMS), irritable bowel syndrome (IBS), and chronic fatigue syndrome (CFS) in relation to timing of federal approvals for FMS drugs.
DATA SOURCE: We used military health care claims from October 2006 to September 2010.
STUDY DESIGN/ANALYSIS: Retrospective, multiple-year comparisons were conducted using trend analyses, and time series regression-based generalized linear models.
RESULTS: Over 5 years, FMS prevalence rates increased from 0.307% to 0.522%, whereas IBS and CFS prevalence rates remained stable. The largest increase in FMS prevalence occurred between 2007 and 2008. Health care utilization was higher for FMS cases compared to IBS and CFS cases. Over 5 years, the total cost for FMS-related care increased $163.2 million, whereas IBS costs increased $14.9 million and CFS cost increased $3.7 million. Between 2006 and 2010, total pharmacy cost for FMS cases increased from $55 million ($3,641/person) to $96.3 million ($3,557/person).
CONCLUSION: Although cause and effect cannot be established, the advent of federally approved drugs for FMS in concert with pharmaceutical industry marketing of these drugs coincide with the observed changes in prevalence, health care utilization, and costs of FMS relative to IBS and CFS.

Abstract
OBJECTIVES: The study investigated the clinical validity of the cognitive screening component of the Military Acute Concussion Evaluation (MACE) for the evaluation of acute mild traumatic brain injury (mTBI) in a military operational setting.
METHODS: This was a retrospective data study involving analysis of MACE data on Operation Enduring Freedom/Operation Iraqi Freedom deployed service members with mTBI. In total, 179 cases were included in analyses based on ICD-9 diagnostic codes and characteristics of mTBI, and availability of MACE data on day of injury. MACE data from the mTBI group was compared to a military sample without mTBI administered the MACE as part of a normative data project.
RESULTS: On day of injury, the mTBI group performed worse than controls on the MACE cognitive test (d = 0.90), with significant impairments in all cognitive domains assessed. MACE cognitive score was strongly associated with established indicators of acute injury severity. Lower MACE cognitive performance on day of injury was predictive of lengthier postinjury recovery time and time until return to duty after mTBI.
CONCLUSIONS: Findings from the current study support the use of the MACE as a valid screening tool to assess for cognitive dysfunction in military service members during the acute phase after mTBI.

Abstract
Measurement of functional impairment is a priority for the military and other professional work groups routinely exposed to stressful traumatic events as part of their occupation. Standard measures of impairment used in general or chronically ill populations contain many items not suitable for these populations, and include mental health symptoms items that are not true measures of functioning. We created a new, 14-item scale-the Walter Reed Functional Impairment Scale-to assess functioning in 4 domains (physical, occupational, social, and personal). We asked 3,380 soldiers how much difficulty they currently have in each of the 4 domains on a 5-point scale. Behaviorally based psychosocial and occupational performance measures and general health questions were used to validate the scale. The utility of the scale was assessed against clinical measures of psychopathology and physical health (depression, posttraumatic stress disorder [PTSD], general health, generalized physical symptoms). We utilized Cronbach's alpha, item response theory, and the score test for trend to establish consistency of items and the validity of the scale. The scale exhibited excellent reliability (Cronbach's α= 0.92) and validity. The individual items and quartiles of sum scores were strongly correlated with negative occupational and social performance, and the utility of the scale was demonstrated by strong correlations with depression, PTSD, and high levels of generalized physical symptoms. This scale exhibits excellent psychometric properties in this sample of U.S. soldiers and, pending future research, is likely to have utility for other healthy occupational groups.

Abstract
This report contains an update through June 2014 of the results of routine screening for antibodies to the human immunodeficiency virus (HIV) among civilian applicants for military service and among members of the active and reserve components of the U.S. Armed Forces. Seroprevalences among civilian applicants in 2013 and the first half of 2014 (0.19 and 0.15 per 1,000 tested, respectively) were markedly lower than in 2012 (0.27 per 1,000 tested). In nearly every component of every service, seroprevalences in 2013 and 2014 were either similar or lower than in prior years; however, in the Army National Guard, seroprevalences increased each year and approximately doubled from 2010 (0.18 per 1,000 tested) to 2013-2014 (0.35-0.41 per 1,000 tested). Among active and reserve component service members, seroprevalences continue to be higher among Army and Navy members and males than their respective counterparts.
