Demographic, Behavioral, and Proximal Risk Factors for Gambling Disorder in the US Military.

BACKGROUND AND OBJECTIVES: To estimate the diagnostic prevalence and incidence of gambling disorder among United States service members and to identify associated risk factors, including demographics, history of mental illness or substance misuse, and proximity to legalized gambling vicinities. METHODS: Gambling disorder cases comprised active component Service members who received a pathological or problem gambling diagnosis between October 1, 2005 and September 30, 2015. There were 901 cases (392 incidents) during the study period. Controls were matched on the case military entrance date (N = 43,564). Geospatial distance between gambling venue and military treatment facilities were calculated, then multivariable logistic regression and survival analyses were conducted. RESULTS: The 10-year prevalence of gambling disorder was 6.6 per 100,000. Men were 3.5 times more likely than women to receive a gambling disorder diagnosis. Other risk factors included age over 24, Asian or Black race, formerly married, and enlisted rank. The odds of gambling disorder increased with duration and proximity to gambling venues, ranging from 2.0 to 3.9. Service members with prior substance misuse or mental health conditions were 3.9 times and 6.3 times more likely to receive a disordered gambling diagnosis than those without substance misuse or mental illness history, respectively. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: The results of this study reveal that proximity to gambling venues and slot machines on bases, as well as a history of substance misuse or mental disorders, are important risk factors for gambling disorder in the US military. Department of Defense screening policies that focus on high-risk populations are appropriate. (Am J Addict 2021;00:00-00).

Establishing an Evidence Synthesis Capability For Psychological Health Topics in the Military Health System.

BACKGROUND: To promote evidence-based health care, clinical providers and decision makers rely on scientific evidence to inform best practices. Evidence synthesis (ES) is a key component of this process that serves to inform health care decisions by integrating and contextualizing research findings across studies. OBJECTIVE: This paper describes the process of establishing an ES capability in the Military Health System dedicated to psychological health topics. RESEARCH DESIGNS: The goal of establishing the current ES capability was to facilitate evidence-based decision-making among clinicians, clinic managers, research funders, and policymakers, through the production and dissemination of trustworthy ES reports. We describe how we developed this capability, provide an overview of the types of evidence syntheses products we use to respond to different stakeholders, and detail the procedures established for selecting and prioritizing synthesis topics. RESULTS: We report on the productivity, acceptability, and impact of our efforts. Our reports were used by a variety of stakeholders and working groups, briefed to major committees, included in official reports and policies, and cited in clinical practice guidelines and the peer-reviewed literature. CONCLUSIONS: Our experiences thus far suggest that the current ES capability offers a needed service within our health system. Our framework may help inform other agencies interested in developing or sponsoring a similar capability.

Present-centered therapy (PCT) for post-traumatic stress disorder (PTSD) in adults.

BACKGROUND: Present-centered therapy (PCT) is a non-trauma, manualized psychotherapy for adults with post-traumatic stress disorder (PTSD). PCT was originally designed as a treatment comparator in trials evaluating the effectiveness of trauma-focused cognitive-behavioral therapy (TF-CBT). Recent trials have indicated that PCT may be an effective treatment option for PTSD and that patients may drop out of PCT at lower rates relative to TF-CBT. OBJECTIVES: To assess the effects of PCT for adults with PTSD. Specifically, we sought to determine whether (1) PCT is more effective in alleviating symptoms relative to control conditions, (2) PCT results in similar alleviation of symptoms compared to TF-CBT, based on an a priori minimally important differences on a semi-structured interview of PTSD symptoms, and (3) PCT is associated with lower treatment dropout as compared to TF-CBT. SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled Trials Register, the Cochrane Library, Ovid MEDLINE, Embase, PsycINFO, PubMed, and PTSDpubs (previously called the Published International Literature on Traumatic Stress (PILOTS) database) (all years to 15 February 2019 search). We also searched the World Health Organization (WHO) trials portal (ICTRP) and ClinicalTrials.gov to identify unpublished and ongoing trials. Reference lists of included studies and relevant systematic reviews were checked. Grey literature searches were also conducted to identify dissertations and theses, clinical guidelines, and regulatory agency reports. SELECTION CRITERIA: We selected all randomized clinical trials (RCTs) that recruited adults diagnosed with PTSD to evaluate PCT compared to TF-CBT or a control condition. Both individual and group PCT modalities were included. The primary outcomes of interest included reduced PTSD severity as determined by a clinician-administered measure and treatment dropout rates. DATA COLLECTION AND ANALYSIS: We complied with the Cochrane recommended standards for data screening and collection. Two review authors independently screened articles for inclusion and extracted relevant data from eligible studies, including the assessment of trial quality. Random-effects meta-analyses, subgroup analyses, and sensitivity analyses were conducted using mean differences (MD) and standardized mean differences (SMD) for continuous data or risk ratios (RR) and risk differences (RD) for dichotomous data. To conclude that PCT resulted in similar reductions in PTSD symptoms relative to TF-CBT, we required a MD of less than 10 points (to include the 95% confidence interval) on the Clinician-Administered PTSD Scale (CAPS). Five members of the review team convened to rate the quality of evidence across the primary outcomes. Any disagreements were resolved through discussion. Review authors who were investigators on any of the included trials were not involved in the qualitative or quantitative syntheses. MAIN RESULTS: We included 12 studies (n = 1837), of which, three compared PCT to a wait-list/minimal attention (WL/MA) group and 11 compared PCT to TF-CBT. PCT was more effective than WL/MA in reducing PTSD symptom severity (SMD -0.84, 95% CI -1.10 to -0.59; participants = 290; studies = 3; I² = 0%). We assessed the quality of this evidence as moderate. The results of the non-inferiority analysis comparing PCT to TF-CBT did not support PCT non-inferiority, with the 95% confidence interval surpassing the clinically meaningful cut-off (MD 6.83, 95% CI 1.90 to 11.76; 6 studies, n = 607; I² = 42%). We assessed this quality of evidence as low. CAPS differences between PCT and TF-CBT attenuated at 6-month (MD 1.59, 95% CI -0.46 to 3.63; participants = 906; studies = 6; I² = 0%) and 12-month (MD 1.22, 95% CI -2.17 to 4.61; participants = 485; studies = 3; I² = 0%) follow-up periods. To confirm the direction of the treatment effect using all eligible trials, we also evaluated PTSD SMD differences. These results were consistent with the primary MD outcomes, with meaningful effect size differences between PCT and TF-CBT at post-treatment (SMD 0.32, 95% CI 0.08 to 0.56; participants = 1129; studies = 9), but smaller effect size differences at six months (SMD 0.17, 95% CI 0.05 to 0.29; participants = 1339; studies = 9) and 12 months (SMD 0.17, 95% CI 0.03 to 0.31; participants = 728; studies = 5). PCT had approximately 14% lower treatment dropout rates compared to TF-CBT (RD -0.14, 95% CI -0.18 to -0.10; participants = 1542; studies = 10). We assessed the quality of this evidence as moderate. There was no evidence of meaningful differences on self-reported PTSD (MD 4.50, 95% CI 3.09 to 5.90; participants = 983; studies = 7) or depression symptoms (MD 1.78, 95% CI -0.23 to 3.78; participants = 705; studies = 5) post-treatment. AUTHORS' CONCLUSIONS: Moderate-quality evidence indicates that PCT is more effective in reducing PTSD severity compared to control conditions. Low quality of evidence did not support PCT as a non-inferior treatment compared to TF-CBT on clinician-rated post-treatment PTSD severity. The treatment effect differences between PCT and TF-CBT may attenuate over time. PCT participants drop out of treatment at lower rates relative to TF-CBT participants. Of note, all of the included studies were primarily designed to test the effectiveness of TF-CBT which may bias results away from PCT non-inferiority.The current systematic review provides the most rigorous evaluation to date to determine whether PCT is comparably as effective as TF-CBT. Findings are generally consistent with current clinical practice guidelines that suggest that PCT may be offered as a treatment for PTSD when TF-CBT is not available.

Identifying research gaps in substance use disorder: A systematic methodology and prioritized list.

Background: This paper presents a new methodology for identifying and prioritizing research gaps, contributing to the nascent literature on systematic ways to identify research gaps. Objectives: The goal of this paper is to report on a gaps analysis of substance use disorder (SUD) research. Based on input from Military Health System stakeholders, we selected the following subtopics as priorities: alcohol use disorder (AUD) and comorbid conditions, prescription opioids, and novel synthetic drugs (NSDs), including synthetic cannabinoids, synthetic cathinones, novel synthetic opioids, and e-cigarette use. Methods: Statements of research needs were extracted from authoritative source reports. A work group of 13 subject matter experts then supplemented, consolidated, and refined the statements. Support for each statement was rated based on predetermined metrics to produce a list of high-priority potential research gaps. Work group members searched both published and ongoing research literature to determine whether these potential gaps were sufficiently addressed in the literature. Finally, to prioritize the gaps, work group members rated them on a set of metrics. Results: The work group reduced 175 statements of research needs to a list of 18 final prioritized gaps: nine for AUD, four for prescription opioids, and five for NSDs. For each topic, we present a prioritized list of gaps. Conclusions: This paper describes a method to identify and prioritize research gaps relevant to military and civilian research and presents the prioritized SUD gaps. Our methodology and findings can inform policy makers, researchers, and funding agencies as they consider investments in future research.

Public health practice is not research.

Scientific and clinical activities undertaken by public health agencies may be misconstrued as medical research. Most discussions of regulatory and legal oversight of medical research focus on activities involving either patients in clinical practice or volunteers in clinical trials. These discussions often exclude similar activities that constitute or support core functions of public health practice. As a result, public health agencies and practitioners may be held to inappropriate regulatory standards regarding research. Through the lens of the Departments of Defense and Veterans Affairs, and using several case studies from these departments, we offer a framework for the adjudication of activities common to research and public health practice that could assist public health practitioners, research oversight authorities, and scientific journals in determining whether such activities require regulatory review and approval as research.

Prevalence of and risk factors for autopsy-determined atherosclerosis among US service members, 2001-2011.

CONTEXT: Autopsies of US service members killed in the Korean and Vietnam wars demonstrated that atherosclerotic changes in the coronary arteries can appear early in the second and third decades of life, long before ischemic heart disease becomes clinically apparent. OBJECTIVE: To estimate the current prevalence of coronary and aortic atherosclerosis in the US armed forces. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional study of all US service members who died of combat or unintentional injuries in support of Operations Enduring Freedom and Iraqi Freedom/New Dawn between October 2001 and August 2011 and whose cardiovascular autopsy reports were available at the time of data collection in January 2012. Prevalence of atherosclerosis was analyzed by various demographic characteristics and medical history. Classifications of coronary atherosclerosis severity were determined prior to data analysis and designed to provide consistency with previous military studies: minimal (fatty streaking only), moderate (10%-49% luminal narrowing of ≥1 vessel), and severe (≥50% narrowing of ≥1 vessel). MAIN OUTCOME MEASURES: Prevalence of coronary and aortic atherosclerosis in the US armed forces and by age, sex, self-reported race/ethnicity, education, occupation, service branch and component, military rank, body mass index at military entrance, and International Classification of Diseases, Ninth Revision, Clinical Modification, diagnoses of cardiovascular risk factors. RESULTS: Of the 3832 service members included in the analysis, the mean age was 25.9 years (range, 18-59 years) and 98.3% were male. The prevalence of any coronary atherosclerosis was 8.5% (95% CI, 7.6%-9.4%); severe coronary atherosclerosis was present in 2.3% (95% CI, 1.8%-2.7%), moderate in 4.7% (95% CI, 4.0%-5.3%), and minimal in 1.5% (95% CI, 1.1%-1.9%). Service members with atherosclerosis were significantly older (mean [SD] age, 30.5 [8.1] years) than those without (mean [SD] age, 25.3 [5.6] years; P < .001). Comparing atherosclerosis prevalence among with those with no cardiovascular risk factor diagnoses (11.1% [95% CI, 10.1%-12.1%]), there was a greater prevalence among those with a diagnosis of dyslipidemia (50.0% [95% CI, 30.3%-69.7%]; age-adjusted prevalence ratio [PR], 2.09 [95% CI, 1.43-3.06]), hypertension (43.6% [95% CI, 27.3%-59.9%]; age-adjusted PR, 1.88 [95% CI, 1.34-2.65]), or obesity (22.3% [95% CI, 15.9%-28.7%]; age-adjusted PR, 1.47 [95% CI, 1.10-1.96]), but smoking (14.1% [95% CI, 8.0%-20.2%]) was not significantly associated with a higher prevalence of atherosclerosis (age-adjusted PR, 1.12 [95% CI, 0.73-1.74]). CONCLUSION: Among deployed US service members who died of combat or unintentional injuries and received autopsies, the prevalence of atherosclerosis varied by age and cardiovascular risk factors.

Estimated incidence of multiple sclerosis among United States Armed Forces personnel using the Defense Medical Surveillance System.

BACKGROUND: The comprehensive longitudinal medical records of the U.S. Armed Forces provide a valuable tool to study the epidemiology of multiple sclerosis (MS) in persons from a diverse demography. OBJECTIVE: This study's objectives were to estimate the frequencies, incidence rates (IRs), trends, and correlates of MS among active component U.S. military members from 2000 to 2009. METHODS: An International Classification of Diseases, 9th Revision, code algorithm was used to identify MS cases from the Defense Medical Surveillance System database. IRs were determined by dividing the number of cases of MS by the total person-time of the active component during each year. RESULTS: During the 10-year period, there were 1,827 incident cases of MS with an overall IR of 12.9 per 100,000 person-years (p-yrs). Black non-Hispanics had a higher IR: (18.3 per 100,000 p-yrs) than White non-Hispanics (12.5 per 100,000 p-yrs). The incidence of MS by birth month and geographic home did not show a clear trend of seasonality or latitudinal gradient. CONCLUSIONS: This investigation is the first longitudinal study of MS incidence in U.S. Armed Forces personnel. The study demonstrates higher IRs than seen in other populations and reveals a novel pattern of MS incidence by race.

Systematic review and meta-analysis of predictors of adjustment disorders in adults.

BACKGROUND: The diagnosis of adjustment disorder is common in clinical practice, yet there is lack of research on the etiology and epidemiology of adjustment disorders. The goal of this systematic review was to evaluate predictors of adjustment disorders in adults. METHODS: We conducted systematic searches in MEDLINE, EMBASE, and PsycINFO. We included 70 studies that examined thirteen theoretically-derived and predefined predictors of adjustment disorders with a total of 3,449,374 participants. RESULTS: We found that female gender, younger age, unemployed status, stress, physical illness and injury, low social support, and a history of mental health disorders predicted adjustment disorders. Most of these predictors differentiated individuals with adjustment disorders from individuals with no mental health disorders. Participants with adjustment disorders were more likely to have experienced accidents than were those with posttraumatic stress disorder but were less likely to have experienced assaults and abuse, neglect, and maltreatment. More research is needed to identify factors that differentiate adjustment disorders from other mental health disorders. LIMITATIONS: Because very few studies adjusted for confounders (e.g., demographic variables, mental health histories, and a variety of stressors), it was not possible to identify independent associations between predictors and adjustment disorders. CONCLUSIONS: We identified a number of factors that predicted adjustment disorders compared to no mental health diagnosis. The majority of studies were rated as moderate or high in risk of bias, suggesting that more rigorous research is needed to confirm the relationships we detected.

Outcomes and prognosis of adjustment disorder in adults: A systematic review.

Adjustment disorder (AD) is one of the most commonly diagnosed mental health disorders and is generally conceptualized to be mild and short-lived. Despite the frequent use of AD in clinical settings, little is known about the prognosis of this condition. Our goal was to systematically review research on a range of AD outcomes in order to provide a broad characterization of AD prognosis. We conducted searches in MEDLINE, EMBASE, and PsycINFO. We included 31 cohort or randomized controlled trials with a total of 1,385,358 participants. Many patients maintained an AD diagnosis or were diagnosed with another mental health disorder months to years after initial diagnosis. Patients with AD tended to show symptom improvement at higher rates and to utilize less treatment than did patients with other disorders. AD-diagnosed groups experienced subsequent development of numerous physical conditions, such as infection, cancers, Parkinson's disease, and cardiovascular events, at higher rates than did control groups. Results were mixed regarding suicidality and occupational impairment. We rated most studies as having a moderate risk of bias. Based on limited findings, AD appears to progress as a milder disorder than do other disorders, but it not uncommonly transitions to more severe mental health states and may predict the development of future health issues, both mental and physical. Future prospective research that conforms to prognosis study guidelines is needed to better understand the course of this common disorder.

Adjustment disorders: A research gaps analysis.

Adjustment disorders are among the most commonly diagnosed mental health disorders in both civilian and military clinical settings. Despite their high prevalence, adjustment disorders have received little research attention. The many gaps in our understanding of this group of disorders hinder the development of adequate, evidence-based treatment protocols. This study utilizes a systematic methodology to identify and prioritize research gaps in adjustment disorders. We used authoritative source reports to identify gaps in research domains from foundational science to services research. Subject-matter experts conducted literature searches to substantiate and refine research gaps, and stakeholders assessed the importance and impact of this work for researchers and policy-makers. We identified 254 possible research-needs statements, which were ultimately reduced to 11 final, prioritized research gaps. Two gaps addressed prevention and screening and three addressed treatment and services research. Six gaps addressed foundational science, epidemiology, and etiology research domains, highlighting the need for basic research. Until some of the basic science questions are resolved (e.g., diagnostic clarity, valid screening, and assessment measures) about adjustment disorders, we may not be able to develop adequate evidence-based interventions for the disorders, and it will be difficult to understand the trajectory of these disorders throughout treatment.

Training initiatives within the AFHSC-Global Emerging Infections Surveillance and Response System: support for IHR (2005).

Training is a key component of building capacity for public health surveillance and response, but has often been difficult to quantify. During fiscal 2009, the Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System (AFHSC-GEIS) supported 18 partner organizations in conducting 123 training initiatives in 40 countries for 3,130 U.S. military, civilian and host-country personnel. The training assisted with supporting compliance with International Health Regulations, IHR (2005). Training activities in pandemic preparedness, outbreak investigation and response, emerging infectious disease (EID) surveillance and pathogen diagnostic techniques were expanded significantly. By engaging local health and other government officials and civilian institutions, the U.S. military's role as a key stakeholder in global public health has been strengthened and has contributed to EID-related surveillance, research and capacity-building initiatives specified elsewhere in this issue. Public health and emerging infections surveillance training accomplished by AFHSC-GEIS and its Department of Defense (DoD) partners during fiscal 2009 will be tabulated and described.

Explosive ordnance disposal personnel in the U.S. military have higher risk of insomnia and post-traumatic stress disorder: a large retrospective cohort study.

PURPOSE: We examined the risk of post-traumatic stress disorder (PTSD), affective disorders, alcohol/substance-related disorders, traumatic brain injury (TBI) and insomnia, among explosive ordnance disposal (EOD) technicians compared to the general population of active-duty non-EOD personnel in the U.S. military. METHODS: We conducted a retrospective cohort study using administrative and healthcare utilization data from fiscal year 2004 (FY2004) to FY2015 for this comparison. We used propensity score matching to balance baseline covariates, and discrete-time hazard models to compare the odds of occurrence of the outcomes. RESULTS: EOD personnel had higher odds of having a new diagnosis of insomnia (odds ratio [OR] = 1.33; 95% confidence interval [CI]:1.22-1.45) and PTSD (OR = 1.23; 95% CI:1.08-1.41) than did non-EOD personnel. EOD technicians had lower odds of having a new diagnosis of affective disorders (OR = 0.83; 95% CI:0.79-0.87) and alcohol/substance-related disorders (OR = 0.59; 95% CI:0.54-0.64) than did non-EOD personnel. There was little evidence of a difference in the odds of a TBI diagnosis (OR = 1.07; 95% CI:0.99-1.16). CONCLUSIONS: As reliance on EOD forces continues, ongoing vigilance of the stressors, health sequelae and disincentives to access mental health care among this military occupation should be monitored and mitigated wherever possible.

Longitudinal Relationship of Combat Exposure With Mental Health Diagnoses in the Military Health System.

INTRODUCTION: Combat deployment is associated with mental and physical health disorders and functional impairment. Mental health (MH) diagnoses such as adjustment and anxiety disorders have received little research attention but may reflect important postdeployment sequelae. The purpose of this study was to investigate the association of combat exposure with the acquisition of a wide range of mental health diagnoses over 2 years. MATERIALS AND METHODS: This retrospective longitudinal study utilized multiple administrative Military Health System datasets compiled for all individuals who entered active duty in the U.S. Army from FY2005 to FY2011. A total eligible cohort of 289,922 Service members was stratified into three mutually exclusive groups according to their deployment status after 2 years in service: Deployed, Combat-Exposed; Deployed, Not-Combat-Exposed; and Not Deployed. Outcomes of interest were new mental health diagnoses grouped into six categories-posttraumatic stress disorder, anxiety, adjustment, mood, substance use disorders, and any MH diagnosis. Survival analyses over 2 years were conducted and adjusted hazard ratios were calculated. RESULTS: Combat exposure in the first 2 years of military service was associated with significantly higher rates of a wide range of mental health diagnoses over a two-year follow-up period, compared with deployment with no combat exposure and no deployment. Adjusted cumulative failure proportions demonstrated that approximately a third of the Combat-Exposed group, a quarter of the Not-Combat-Exposed, and a fifth of the Not Deployed groups received a MH diagnosis over 2 years. For all groups, cumulative failure proportions and incidence rates were highest for adjustment disorder and lowest for posttraumatic stress disorder diagnoses. CONCLUSIONS: Researchers and providers should be alerted to the impact of combat exposure and the wide range of MH conditions and diagnoses that may represent important postdeployment sequelae.

A systematic analysis and prioritization of suicide prevention research gaps.

OBJECTIVE: This study identified and prioritized research gaps for suicide prevention in the Department of Defense to inform future research investments. METHODS: The 2019 VA/DoD Clinical Practice Guideline for the Assessment and Management of Patients at Risk for Suicide was the primary source document for research gaps, supplemented by an updated literature search. Institutional stakeholders rated the identified research gaps and ranked the gap categories. We used Q factor analysis to derive a list of the prioritized research gaps and category rankings. RESULTS: Thirty-five research gaps were identified and prioritized. The highest rated research gap topic was lethal means safety interventions and their effectiveness in increasing safety behaviors and/or reducing suicide-related outcomes. Research on the effectiveness of crisis response planning and several other non-pharmacological interventions (e.g., implementation of cognitive-behavioral therapy, technology-based behavioral interventions, and applications of dialectical behavior therapy to non-Borderline patients) were also rated highly by stakeholders. CONCLUSIONS: This work generated a list of priorities for future suicide research as evaluated by Departments of Defense and Veterans Affairs stakeholders. Our findings can help guide the efforts of suicide researchers and inform decisions about future research funding for suicide prevention.

Preparing military installations for pandemic influenza through tabletop exercises.

Effective Department of Defense (DoD) response to pandemic influenza requires robust and well-exercised plans at the installation level. This article describes proceedings and key findings from a half-day "train-the-trainer" pandemic influenza tabletop exercise for Tri-Service installation public health emergency officers (PHEOs) at the August 2008 Force Health Protection conference. Exercise participants were expected to facilitate the execution of a pandemic influenza exercise at their respective installations within 6 months of attendance. On a 6-month follow-up survey (N= 50), 68% indicated their installations had since created a new pandemic influenza plan or revised an existing one, whereas 44% indicated that their installation had since conducted a pandemic influenza exercise. Chief reported barriers to conducting installation-level pandemic influenza exercises included competing priorities, followed by time, personnel, and budget limitations. Relevant policy implications for installation-level pandemic influenza readiness include access to higher level plans, strategic utilization of assets to optimize surge capacity, and cross-training of personnel.

A systematic review evaluating screening instruments for gambling disorder finds lack of adequate evidence.

OBJECTIVES: To date, no research has systematically evaluated screening instruments for gambling disorder to assess their accuracy and the quality of the research. This systematic review evaluated screening instruments for gambling disorder to inform decision makers about choices for population-level screening. STUDY DESIGN AND SETTING: On May 22, 2017 and January 4, 2019, we searched PubMed, PsycInfo, EMBASE, and Cochrane for studies that evaluated screening instruments for gambling disorder. Studies were included if (1) the screening instrument was in English, (2) the screening instrument was compared to a reference standard semistructured interview based on Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases diagnoses of gambling disorder, and (3) data were reported on psychometric properties of the instrument. RESULTS: We identified 31 different screening instruments from 60 studies. Only three instruments from three separate studies were eligible for inclusion in the systematic review. CONCLUSION: Few screening instruments for gambling disorder have been validated with sufficient methodological quality to be recommended for use across a large health system.

Seasonal and environmental determinants of leptospirosis and scrub typhus in small mammals captured at a U.S. military training site (Dagmar North), Republic of Korea, 2001-2004.

OBJECTIVE: This study sought to identify seasonal and environmental determinants of scrub typhus, murine typhus, and leptospirosis in small mammals trapped at Dagmar North training area, Gyeonggi Province, South Korea. METHODS: Small mammals received titer assays to the aforementioned diseases. Logistic regression analyses were conducted to determine whether associations existed between risk of small-mammal infection and independent variables such as season of capture, habitat, small-mammal species, and sex. RESULTS: Murine typhus was not detected among the animals assayed. Risk of scrub typhus infection was associated with season, habitat, and small-mammal species. Risk of leptospirosis infection was associated with season and habitat. CONCLUSIONS: These findings indicate determinants of infection exist for scrub typhus and leptospirosis at this training site. This information can be used for developing appropriate preventive medicine plans and coordinating troop activity during periods of reduced exposure decreasing the likelihood of disease transmission to humans.

Evaluating measures of combat deployment for U.S. Army personnel using various sources of administrative data.

PURPOSE: This study's purpose is to inform future research decisions about optimal measures for identifying combat deployments. We aim to evaluate four commonly utilized measures available in population-level administrative data to identify combat deployments in recent military operations among active duty Army personnel. METHODS: We compare these measures in three ways: (1) agreement (assessing the extent to which soldiers were differentially identified as combat deployed via each measure); (2) validity (calculating the sensitivity of each measure against a criterion measure); and (3) corroboration (examining how each measure predicted subsequent incidence of traumatic brain injury and post-traumatic stress disorder). RESULTS: We found that using personnel records to identify deployments to Iraq, Afghanistan, and/or Kuwait captured over 98% of combat-related deployments identified via self-reported measures. The addition of Kuwait allowed for detection of nearly 100% of battle injuries, improving sensitivity from 94.5% to 99.8%. However, self-reported combat exposure measures showed the largest differential in subsequent incidence of traumatic brain injury and post-traumatic stress disorder. Completeness and accuracy of different combat deployment measures varied significantly. CONCLUSIONS: Using personnel records to identify deployment to Iraq, Afghanistan, and/or Kuwait was the most valid and comprehensive measure of combat deployment. However, self-reported combat exposure measures were more predictive of combat-related outcomes.

Ethics and severe pandemic influenza: maintaining essential functions through a fair and considered response.

The response to severe pandemic influenza will be managed by experts in public health and infectious disease and by government officials to whom the public will turn for information and direction. Nonetheless, there remain important ethical considerations that can shape what goals are given priority, how scarce resources are distributed, how the public is included, and how we treat the most vulnerable in our response to a pandemic. This article assumes that the secondary consequences of severe pandemic influenza could be greater than deaths and illness from influenza itself. Response plans, then, must consider threats to societal as well as medical infrastructures. While some have suggested that scarce medical countermeasures be allocated primarily to first responders and then to the sickest, we suggest that an ethical public health response should set priorities based on essential functions. An ethical response also will engage the public, will coordinate interdependent sectors as a core preparedness priority, and will address how plans affect and can be understood by the least well off.
