Subthreshold posttraumatic stress disorder (PTSD) is associated with increased risk for suicidality, depression, and functional impairment. We thus conducted a small (N=12) pilot randomized controlled trial (RCT) with paroxetine for subthreshold PTSD in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) era veterans. Hospital Anxiety and Depression Scale (HADS) scores improved by 30.4% in the paroxetine group. Paroxetine may have promise for subthreshold PTSD. ...[more]

Project description:BackgroundProblems with anger and aggression are highly prevalent in Veterans of multiple war eras, including the most recent conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF). The consequences of these problems, such as increased rates of divorce, domestic violence, occupational instability, arrests and incarceration, are often devastating. Despite the seriousness of these problems, relatively little is known about effective treatments for anger in Veterans.Method and designThis paper describes the rationale and study protocol of a randomized controlled trial comparing an adapted cognitive behavioral intervention (CBI) with an active control condition (supportive intervention, SI) for the treatment of anger problems in OEF/OIF Veterans. The sample includes 92 OEF/OIF Veterans, randomized to CBI or SI. Both treatments include 12 weekly, 75-min individual sessions. Participants are assessed at baseline, after sessions 4 and 8, at post-treatment, and at 3 and 6 months post-treatment. Primary outcomes are reduction in anger and aggression; secondary outcomes are improved functioning and quality of life. We hypothesize that CBI will be associated with significantly more improvement than SI on primary and secondary measures.DiscussionFindings from this study will help to address the gap in evidence for effective treatments for anger in Veterans. The use of an active control condition will provide a stringent test of the effects of CBI beyond that of common factors of psychotherapy such as therapeutic relationship, mobilization of hope, and support. Findings have the potential to improve treatment outcomes for Veterans struggling with post-deployment anger problems.

Project description:This study examines whether the relationship between traumatic brain injury (TBI) and post-deployment binge drinking is independent of screening positive for mental health problems among male and female service members. Data are from the Substance Use and Psychological Injury Combat Study of Army members returning from deployment to Afghanistan or Iraq in fiscal years 2008-2011. The sample consists of 240,694 male and 26,406 female active duty members who completed initial and follow-up questionnaires. The initial questionnaire, completed at the end of deployment, included screens for TBI and mental health problems (post-traumatic stress disorder, depression, harmful thoughts). The dependent variable, frequent binge drinking (six or more drinks on one occasion, at least monthly), was assessed on the follow-up questionnaire on average 3-9 months post-deployment. More than 21% of males and 7% of females reported frequent binge drinking. Male members were more likely to screen positive for TBI, compared with females (7.5% vs. 4.4%). Females with both TBI and mental health positive screens had more than double the risk of frequent binge drinking, compared with those without either problem (15.8% vs. 6.6%), and males with both problems had almost double the risk, compared with males with neither problem (33.6% vs. 19.7%). In multivariable logistic regression models, having a TBI and a comorbid positive mental health screen was associated with increased odds of frequent binge drinking among both males and females (adjusted odds ratio [AOR] = 1.59, CI: 1.50-1.69, and AOR = 2.11, CI: 1.57-2.83, respectively), compared with those with neither condition. More research is needed on the interaction of gender and binge drinking, especially when TBI and mental health problems co-exist.

Project description:ObjectivePosttraumatic stress disorder is a chronic, debilitating condition that has become a growing concern among combat veterans. Previous research suggests that posttraumatic stress disorder disrupts normal autonomic responding and may increase the risk of cardiovascular disease and mortality. Measures of heart rate variability and QT interval variability have been used extensively to characterize sympathetic and parasympathetic influences on heart rate in a variety of psychiatric populations. The objective of this study was to better understand the effects of pharmacological treatment on autonomic reactivity in posttraumatic stress disorder.DesignA 12-week, Phase IV, prospective, open-label trial of escitalopram in veterans with combat-related posttraumatic stress disorder and comorbid depression.SettingAn outpatient mental health clinic at a Veterans Affairs Medical Center.ParticipantsEleven male veterans of Operations Enduring Freedom and Iraqi Freedom diagnosed with posttraumatic stress disorder and comorbid depression.MeasurementsAutonomic reactivity was measured by examining heart rate variability and QT interval variability. Treatment safety and efficacy were also evaluated pre- and post-treatment.ResultsWe observed a reduction in posttraumatic stress disorder and depression symptoms from pre- to post-treatment, and escitalopram was generally well tolerated in our sample. In addition, we observed a decrease in high frequency heart rate variability and an increase in QT variability, indicating a reduction in cardiac vagal function and heightened sympathetic activation.ConclusionThese findings suggest that escitalopram treatment in patients with posttraumatic stress disorder and depression can trigger changes in autonomic reactivity that may adversely impact cardiovascular health.

Project description:BackgroundThe U.S. Department of Veterans Affairs (VA) implemented the Polytrauma System of Care to meet the health care needs of military and veterans with multiple injuries returning from combat operations in Afghanistan and Iraq. Studies are needed to systematically assess barriers to use of comprehensive and exclusive VA healthcare services from the perspective of veterans with polytrauma and with other complex health outcomes following their service in Afghanistan and Iraq. These perspectives can inform policy with regard to the optimal delivery of care to returning veterans.MethodsWe studied combat veterans (n = 359) from two polytrauma rehabilitation centers using structured clinical interviews and qualitative open-ended questions, augmented with data collected from electronic health records. Our outcomes included several measures of exclusive utilization of VA care with our primary exposure as reported access barriers to care.ResultsNearly two thirds of the veterans reported one or more barriers to their exclusive use of VA healthcare services. These barriers predicted differences in exclusive use of VA healthcare services. Experiencing any barriers doubled the returnees' odds of not using VA exclusively, the geographic distance to VA barrier resulted in a 7 fold increase in the returnees odds of not using VA, and reporting a wait time barrier doubled the returnee's odds of not using VA. There were no striking differences in access barriers for veterans with polytrauma compared to other returning veterans, suggesting the barriers may be uniform barriers that predict differences in using the VA exclusively for health care.ConclusionsThis study provides an initial description of utilization of VA polytrauma rehabilitation and other medical care for veteran returnees from all military services who were involved in combat operations in Afghanistan or Iraq. Our findings indicate that these veterans reported important stigmatization and barriers to receiving services exclusively from the VA, including mutable health delivery system factors.

Project description:We estimated the temporal course of posttraumatic stress disorder (PTSD) in Vietnam-era veterans using a national sample of male twins with a 20-year follow-up. The complete sample included those twins with a PTSD diagnostic assessment in 1992 and who completed a DSM-IV PTSD diagnostic assessment and a self-report PTSD checklist in 2012 (n = 4,138). Using PTSD diagnostic data, we classified veterans into 5 mutually exclusive groups, including those who never had PTSD, and 4 PTSD trajectory groups: (a) early recovery, (b) late recovery, (c) late onset, and (d) chronic. The majority of veterans remained unaffected by PTSD throughout their lives (79.05% of those with theater service, 90.85% of those with nontheater service); however, an important minority (10.50% of theater veterans, 4.45% of nontheater veterans) in 2012 had current PTSD that was either late onset (6.55% theater, 3.29% nontheater) or chronic (3.95% theater, 1.16% nontheater). The distribution of trajectories was significantly different by theater service (p < .001). PTSD remains a prominent issue for many Vietnam-era veterans, especially for those who served in Vietnam.

Project description:Older veterans with posttraumatic stress disorder (PTSD) are at increased risk of obesity and cardiometabolic disease. Physical activity and healthy eating are two behaviors that impact health, functional independence, and disease risk in later life, yet few studies have examined the relationship between PTSD and diet quality. This secondary analysis aimed to: (a) characterize the diet quality of older veterans with PTSD in comparison to U.S. dietary guidelines and (b) explore if participation in a supervised exercise intervention spurred simultaneous changes in dietary behavior. Diet quality was assessed with the Dietary Screener Questionnaire (DSQ), which measures daily intake of fiber, calcium, added sugar, whole grain, dairy, and fruits/vegetables/legumes. The sample included 54 military veterans ≥ 60 years old with PTSD who participated in a randomized controlled pilot trial comparing 12 weeks of supervised exercise (n = 36) to wait-list usual care (n = 18). The DSQ was administered at baseline and 12 weeks. Consumption of added sugar exceeded U.S. dietary guideline recommendations and consumption of whole grains, fruits/vegetables/legumes, fiber, calcium, and dairy fell short. Participation in the supervised exercise intervention was not associated with changes in diet quality. Results revealed that the diet quality of older veterans with PTSD is poor, and while the exercise intervention improved health through exercise, it did not make veterans any more likely to adopt a more healthful diet. Interventions targeting diet, or diet + exercise, are needed to manage the increased risk of obesity and cardiometabolic disease present in older veterans with PTSD.

Project description:Exercise training positively impacts mental health, yet remains untested in older adults with posttraumatic stress disorder (PTSD). We conducted a randomized controlled pilot trial to test the feasibility and acceptability of exercise training in older veterans with PTSD. Fifty-four veterans ≥ 60 years, with a DSM-V diagnosis of PTSD, were randomized to supervised exercise (n = 36) or wait-list (WL; n = 18). Primary outcomes included recruitment rates, attendance, satisfaction, and retention. Secondary outcomes included changes in PTSD symptoms, depression, health-related quality of life, and sleep quality; assessed at baseline and 12 weeks. There were no adverse events. Attrition was minimal (14%), and adherence to the exercise intervention was high (82%). Clinically significant improvements in PTSD and related conditions were observed following exercise (Cohen's d = 0.36-0.81). Exercise training is safe and acceptable in older adults with PTSD, may improve PTSD symptoms, and broadly impacts PTSD-related conditions. Future definitive trials are warranted.

Project description:Purpose: RNA-Seq analysis can help identify large set of differentially expressed genes at a time. We performed RNA-Seq analysis to identify differentially expressed genes in the PBMCs of war veterans suffering from PTSD. Methods: Total RNA from PBMCs from PTSD +ve and -ve individuals were used for RNA-Seq analysis. Results: We obtained, on average, ~60 millions reads per sample. More than 70% of the reads were mapped to human genome. Functional analysis of the differentially expressed genes (362) revealed dysregulation in immune system network. Conclusions: Our present study provides further proof that immune system related genes and pathways are dysregulated in PTSD PBMCs.

Project description:The apolipoprotein E (APOE) ?4 allele has been implicated in a range of neuropsychiatric conditions. The present research examined if the ?4 allele of the APOE gene moderated the effect of combat exposure on posttraumatic stress disorder (PTSD) among Iraq/Afghanistan-era veterans.Participants included 765 non-Hispanic White (NHW) and 859 non-Hispanic Black (NHB) Iraq/Afghanistan-era veterans. A structured interview established psychiatric diagnoses. Combat exposure and PTSD symptom severity were assessed via self-report.The most common lifetime diagnoses were depression (39.2%), PTSD (38.4%), and alcohol dependence (24.38%). After correcting for multiple comparisons, no significant effects were observed on any of the outcomes among the NHW sample; however, within the NHB sample, significant gene × environment (G × E) interactions were observed for lifetime PTSD (P = .0029) and PTSD symptom severity (P = .0009). In each case, the APOE ?4 allele had no effect on the outcomes when combat exposure was low; however, when combat exposure was high, an additive effect was observed such that ?4 homozygotes exposed to high levels of combat reported the highest rates of PTSD (92%) and the worst symptom severity scores on the Davidson Trauma Scale (M = 79.5).Although preliminary, these findings suggest that the APOE ?4 allele, in conjunction with exposure to high levels of combat exposure, may increase veterans' risk for developing PTSD.

Project description:With a host of new materials being investigated as active layers in organic electrochemical transistors (OECTs), several advantageous characteristics can be utilized to improve transduction and circuit level performance for biosensing applications. Here, the subthreshold region of operation of one recently reported high performing OECT material, poly(2-(3,3'-bis(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)-[2,2'-bithiophen]-5-yl)thieno[3,2-b]thiophene), p(g2T-TT) is investigated. The material's high subthreshold slope (SS) is exploited for high voltage gain and low power consumption. An ≈5× improvement in voltage gain (AV) for devices engineered for equal output current and 370× lower power consumption in the subthreshold region, in comparison to operation in the higher transconductance (gm), superthreshold region usually reported in the literature, are reported. Electrophysiological sensing is demonstrated using the subthreshold regime of p(g2T-TT) devices and it is suggested that operation in this regime enables low power, enhanced sensing for a broad range of bioelectronic applications. Finally, the accessibility of the subthreshold regime of p(g2T-TT) is evaluated in comparison with the prototypical poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and the role of material design in achieving favorable properties for subthreshold operation is discussed.
