Abstract
Background Incorporating genomic data into risk prediction has become an increasingly useful approach for rapid identification of individuals most at risk for complex disorders such as PTSD. Our goal was to develop and validate Methylation Risk Scores (MRS) using machine learning to distinguish individuals who have PTSD from those who do not. Methods Elastic Net was used to develop three risk score models using a discovery dataset (n = 1226; 314 cases, 912 controls) comprised of 5 diverse cohorts with available blood-derived DNA methylation (DNAm) measured on the Illumina Epic BeadChip. The first risk score, exposure and methylation risk score (eMRS) used cumulative and childhood trauma exposure and DNAm variables; the second, methylation-only risk score (MoRS) was based solely on DNAm data; the third, methylation-only risk scores with adjusted exposure variables (MoRSAE) utilized DNAm data adjusted for the two exposure variables. The potential of these risk scores to predict future PTSD based on pre-deployment data was also assessed. External validation of risk scores was conducted in four independent cohorts. Results The eMRS model showed the highest accuracy (92%), precision (91%), recall (87%), and f1-score (89%) in classifying PTSD using 3730 features. While still highly accurate, the MoRS (accuracy = 89%) using 3728 features and MoRSAE (accuracy = 84%) using 4150 features showed a decline in classification power. eMRS significantly predicted PTSD in one of the four independent cohorts, the BEAR cohort (beta = 0.6839, p-0.003), but not in the remaining three cohorts. Pre-deployment risk scores from all models (eMRS, beta = 1.92; MoRS, beta = 1.99 and MoRSAE, beta = 1.77) displayed a significant (p < 0.001) predictive power for post-deployment PTSD. Conclusion Results, especially those from the eMRS, reinforce earlier findings that methylation and trauma are interconnected and can be leveraged to increase the correct classification of those with vs. without PTSD. Moreover, our models can potentially be a valuable tool in predicting the future risk of developing PTSD. As more data become available, including additional molecular, environmental, and psychosocial factors in these scores may enhance their accuracy in predicting the condition and, relatedly, improve their performance in independent cohorts.

Association of homelessness and diet on the gut microbiome: a United States-Veteran Microbiome Project (US-VMP) study. mSystems 2024; 9:e0102123.

Abstract
Military veterans account for 8% of homeless individuals living in the United States. To highlight associations between history of homelessness and the gut microbiome, we compared the gut microbiome of veterans who reported having a previous experience of homelessness to those from individuals who reported never having experienced a period of homelessness. Moreover, we examined the impact of the cumulative exposure of prior and current homelessness to understand possible associations between these experiences and the gut microbiome. Microbiome samples underwent genomic sequencing and were analyzed based on alpha diversity, beta diversity, and taxonomic differences. Additionally, demographic information, dietary data, and mental health history were collected. A lifetime history of homelessness was found to be associated with alcohol use disorder, substance use disorder, and healthy eating index compared to those without such a history. In terms of differences in gut microbiota, beta diversity was significantly different between veterans who had experienced homelessness and veterans who had never been homeless (P = 0.047, weighted UniFrac), while alpha diversity was similar. The microbial community differences were, in part, driven by a lower relative abundance of Akkermansia in veterans who had experienced homelessness (mean; range [in percentages], 1.07; 0-33.9) compared to veterans who had never been homeless (2.02; 0-36.8) (P = 0.014, ancom-bc2). Additional research is required to facilitate understanding regarding the complex associations between homelessness, the gut microbiome, and mental and physical health conditions, with a focus on increasing understanding regarding the longitudinal impact of housing instability throughout the lifespan.IMPORTANCEAlthough there are known stressors related to homelessness as well as chronic health conditions experienced by those without stable housing, there has been limited work evaluating the associations between microbial community composition and homelessness. We analyzed, for the first time, bacterial gut microbiome associations among those with experiences of homelessness on alpha diversity, beta diversity, and taxonomic differences. Additionally, we characterized the influences of diet, demographic characteristics, military service history, and mental health conditions on the microbiome of veterans with and without any lifetime history of homelessness. Future longitudinal research to evaluate the complex relationships between homelessness, the gut microbiome, and mental health outcomes is recommended. Ultimately, differences in the gut microbiome of individuals experiencing and not experiencing homelessness could assist in identification of treatment targets to improve health outcomes.

Abstract
Sexual minority women (SMW; e.g., lesbian, bisexual) report higher rates of almost every negative physical health (e.g., asthma, arthritis, cardiovascular disease), mental health (e.g., depression, anxiety), and substance use outcome compared to heterosexual women. Adverse Childhood Experiences (ACEs) have been identified as risk factors for negative health outcomes. Despite this, no study to date has synthesized existing literature examining ACEs and health outcomes among SMW. This gap is important because SMW are significantly more likely than heterosexual women to report every type of ACE and a higher total number of ACEs. Therefore, using a scoping review methodology, we sought to expand understanding of the relationship between ACEs and health outcomes among SMW. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for. Scoping Reviews protocol, we searched five databases: Web of Science, PsycInfo, CINAHL, PubMed, and Embase for studies published between January 2000 and June 2021 that examined mental health, physical health, and/or substance use risk factors and outcomes among adult cisgender SMW who report ACEs. Our search yielded 840 unique results. Studies were screened independently by two authors to determine eligibility, and 42 met full inclusion criteria. Our findings provide strong evidence that ACEs are an important risk factor for multiple negative mental health and substance use outcomes among SMW. However, findings were mixed with respect to some health risk behaviors and physical health outcomes among SMW, highlighting the need for future research to clarify these relationships.

Abstract
The intricate relationship between post-traumatic stress disorder (PTSD) and cardiovascular disease (CVD) has garnered increasing attention due to its bidirectional impact and potential for significant health consequences. Epidemiological evidence suggests that PTSD may serve as a risk factor for incident CVD, while acute CVD events can trigger PTSD, subsequently increasing the risk of recurrent cardiovascular events. This dynamic interplay is characterized by the human stress response, disrupted behavioral and lifestyle factors, and potential physiological mechanisms. Notably, the immediate aftermath of a cardiovascular event presents a critical window for intervention, offering the possibility of preventing the development of PTSD and its associated physiological and behavioral sequelae. However, while candidate mechanisms linking PTSD and CVD have been identified, determining which mechanisms are most amenable to intervention remains a challenge. This article emphasizes the urgency of addressing key unanswered questions in this domain. Despite an evolving understanding of the association between PTSD and CVD, causal relationships remain to be firmly established. Comprehensive investigations into the intricate interplay of behavioral and biological mechanisms are essential for identifying precise targets for intervention. Innovations in research methodologies, including the exploration of PTSD symptom dynamics and their impact on cardiovascular function, hold the potential for identifying crucial intervention points. Drawing parallels from prior challenges in translating identified risk factors into effective interventions, the field must prioritize systematic investigations and early-phase intervention trials. By doing so, researchers and clinicians can potentially develop strategies to mitigate CVD risk in the context of PTSD and improve both cardiovascular and mental health outcomes.

Abstract
BACKGROUND Bullying victimization is highly prevalent among sexual minority youths, particularly in educational settings, negatively affecting their mental health. However, previous studies have scarcely explored the symptomatic relationships among anxiety, depression, and posttraumatic stress disorder (PTSD) among sexual minority youths who experienced bullying on college campuses. OBJECTIVE The objectives of our study were to (1) characterize the anxiety-depression-PTSD network structures of gay or lesbian, bisexuals, and other sexual minority youths previously bullied on college campuses; and (2) compare symptomatic associations in the anxiety-depression-PTSD networks among bullied sexual minority youths and heterosexual youths' groups. METHODS This cross-sectional study recruited college participants from Jilin Province, China. Data were analyzed using a subset of the data extracted after screening for sexual orientation and history of bullying victimization. Sexual minority youths were then divided into 3 subgroups: gay or lesbian (homosexual), bisexual, and other. Mental health symptom severity was assessed using scales: the 7-item Generalized Anxiety Disorder Scale measuring anxiety, the 9-item Patient Health Questionnaire measuring depression, and the 10-item Trauma Screening Questionnaire measuring PTSD symptoms. Combining the undirected and Bayesian network analyses, the anxiety-depression-PTSD networks were compared among sexual minority youths subgroups, and the difference between heterosexual youths and sexual minority youths was investigated. Chi-square tests were used to compare the difference in categorical variables, while independent-sample t tests were run on continuous variables. RESULTS In this large-scale sample of 89,342 participants, 12,249 identified as sexual minority youths, of which 1603 (13.1%, 95% CI 12.5%-13.7%) reported being bullied on college campuses in the past year. According to the expected influence (EI) and bridge expected influence (bEI) index, in the global network structure of anxiety, depression, and PTSD, sad mood (EI=1.078, bEI=0.635) and irritability (EI=1.077, bEI=0.954) were identified as central and bridge symptoms; emotional cue reactivity (EI=1.015) was a central symptom of PTSD in this global network. In the anxiety-depression-PTSD Bayesian network, anhedonia had the highest prediction priority for activating other symptoms; and feeling afraid linked symptoms from anxiety to the PTSD community. Compared to their heterosexual counterparts, sexual minority youths exhibited a stronger association between difficulty concentrating and appetite. The "sad mood-appetite" edge was strongest in the gay or lesbian network; the "irritability-exaggerated startle response" edge was strongest in the bisexual network. CONCLUSIONS For the first time, this study identified the most central and bridge symptoms (sad mood and irritability) within the depression-anxiety-PTSD network of sexual minority youths with past bullying-victim experiences on college campuses. Emotional cue reactivity, anhedonia, and feeling afraid were other vital symptoms in the comorbid network. Symptomatic relationships existed showing heterogeneity in bullied heterosexual youths and sexual minority youth networks, which also was present within the sexual minority youth subgroups. Consequently, refined targeted interventions are required to relieve anxiety, depression, and PTSD symptoms.

Abstract
Background Pregnancy loss has been associated with myocardial infarction, stroke, and all-cause mortality in women through unknown mechanisms. The aim of this study was to examine these associations in women and their male partners. Methods and Results In this register-based cohort study, all people born between 1957 and 1997, residing in Denmark between 1977 and 2017, and with a registered partner of the opposite sex were eligible for inclusion. Male partners through cohabitation, marriage, or paternity constituted the male cohort. Exposure to pregnancy loss was categorized as follows: 0, 1, 2, or ≥3 pregnancy losses. The outcomes of interest were myocardial infarction, stroke, and all-cause mortality. The Cox proportional hazards model estimated hazard ratios (HRs), adjusted for age, calendar year, parity, and parental history of myocardial infarction or stroke. During follow-up, 1 112 507 women experienced 4463 events of myocardial infarction compared with 13 838 events among 1 120 029 male partners. With the no pregnancy loss group as reference, the adjusted HRs of myocardial infarction in the female cohort after 1, 2, and ≥3 pregnancy losses were as follows: 1.1 (95% CI, 1.0-1.2), 1.3 (95% CI, 1.1-1.5), and 1.4 (95% CI, 1.1-1.8), respectively. In the male partner cohort, the corresponding estimates were 1.0 (95% CI, 1.0-1.1), 1.1 (95% CI, 1.0-1.2), and 1.0 (95% CI, 0.8-1.2), respectively. The outcome of stroke showed similar results. Pregnancy loss was not significantly associated with increased mortality in either sex. Conclusions Pregnancy loss or stillbirth was significantly associated with myocardial infarction and stroke in women but not their male partners. Pregnancy loss or stillbirth was not significantly associated with all-cause mortality in women or male partners.

Public Health 2023; 221:208-215. [PMID: 37490839 DOI: 10.1016/j.puhe.2023.06.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 05/22/2023] [Accepted: 06/15/2023] [Indexed: 07/27/2023]
Abstract
OBJECTIVES North Korean Refugees (NKRs) undergo defection, and this has been shown to impact their current health status in South Korea. However, little is understood about how the defection process is related to metabolic syndrome (MetS). This study regarded the defection process to be a quasi-measurement of traumatic experience and investigated whether defection was a risk factor for MetS among NKRs living in South Korea. STUDY DESIGN This cross-sectional study obtained data from the Korea University Anam Hospital in Seoul. NKRs (N = 847) voluntarily completed questionnaires and underwent at least one medical examination between October 2008 and July 2021. METHODS Multivariable logistic regression models were used to evaluate whether the number of countries transited by NKRs was associated with MetS by controlling for covariates. RESULTS The prevalence of MetS among male and female NKRs in South Korea was 12.3% and 13.3%, respectively. The highest prevalence of MetS (33.4%) was among NKRs who had transited two countries. The number of months in transit countries (mean: 49.9 ± 51.7) and period of residence in South Korea (mean: 40.9 ± 40.9 months) were also considered. NKRs who transited three countries had a higher probability of MetS (odds ratio [OR] 2.660, 95% confidence interval [CI] 1.161-6.097) than those who travelled directly to South Korea. NKRs who transited three countries and had only resided in South Korea for a short period had a higher probability of MetS (OR 3.424, 95% CI 1.149-10.208) than those who have lived in South Korea for a longer period. CONCLUSIONS Considering the social vulnerability of NKRs and consequential health problems, there is an urgent need for appropriate support from the government and society.

Abstract
Objectives: Posttraumatic stress disorder (PTSD) has been linked with cardiovascular disease (CVD), suggesting a risk for negative health outcomes among individuals with PTSD. This review synthesizes the temporal relationship between PTSD and CVD and highlights the intersection of sex and race. Methods: Covidence was used to systematically review the literature published between 1980 and 2020. Results: 176 studies were extracted. 68 (38.64%) of the studies were a predominantly male sample. 31 studies (17.61%) were a predominantly female sample. Most reported participants of both sexes (n = 72; 40.91%) and only 5 (2.84%) did not report respondent sex. No studies reported transgender participants. 110 (62.5%) studies reported racial and ethnic diversity in their study population, 18 (10.22%) described a completely or predominantly white sample, and 48 (27.27%) did not report race or ethnicity of their study population. Conclusion: A compelling number of studies did not identify sex differences in the link between PTSD and CVD or failed to report race and ethnicity. Investigating sex, race, ethnicity, and the temporal relationship between PTSD and CVD are promising avenues for future research.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) is associated with cardiometabolic diseases, concurrent anxiety, alcohol use disorder and depression. The relationship between PTSD and cardiometabolic diseases are still unclear, and less is known about the effects of socioeconomic status, comorbid anxiety, comorbid alcohol use disorder and comorbid depression. The study, therefore, aims to examine the risk of developing cardiometabolic diseases including type 2 diabetes mellitus over time in PTSD patients, and to what extent socioeconomic status, comorbid anxiety, comorbid alcohol use disorder and comorbid depression attenuate associations between PTSD and risk of developing cardiometabolic diseases. METHOD A retrospective, register-based cohort study with 6-years follow-up of adult (> 18 years) PTSD patients (N = 7 852) compared with the general population (N = 4 041 366), was performed. Data were acquired from the Norwegian Patient Registry and Statistic Norway. Cox proportional regression models were applied to estimate hazard ratios (HRs) (99% confidence intervals) of cardiometabolic diseases among PTSD patients. RESULTS Significantly (p < 0.001) higher age and gender adjusted HRs were disclosed for all cardiometabolic diseases among PTSD patients compared to the population without PTSD, with a variation in HR from 3.5 (99% CI 3.1-3.9) for hypertensive diseases to HR = 6.5 (5.7-7.5) for obesity. When adjusted for socioeconomic status and comorbid mental disorders, reductions were observed, especially for comorbid depression, for which the adjustment resulted in HR reduction of about 48.6% for hypertensive diseases and 67.7% for obesity. CONCLUSIONS PTSD was associated with increased risk of developing cardiometabolic diseases, though attenuated by socioeconomic status and comorbid mental disorders. Health care professionals should be attentive towards the burden and increased risk that low socioeconomic status and comorbid mental disorders may represent for PTSD patients' cardiometabolic health.

Abstract
PURPOSE OF REVIEW To provide an update of the current evidence of cardiac disease-induced posttraumatic stress disorder (CDI-PTSD) with a focus on acute coronary events. RECENT FINDINGS A cardiovascular disease, particularly a life-threatening cardiac event is often a highly stressful experience that can induce PTSD in patients and their caregivers, taking a chronic course if left untreated. There are several features distinguishing CDI-PTSD from "traditional" PTSD induced by external trauma, namely enduring somatic threat, inability to avoid trauma-related cues and hyperarousal with internal body sensations leading to constant fear of recurrent cardiac events. An increased risk of recurrent CVD events may be explained by pathophysiological changes, an unhealthy lifestyle and non-adherence to cardiac treatment. A trauma-focused approach might be useful to treat CDI-PTSD. Treatment options for patients and caregivers as well as long-term effects of trauma-focused interventions on physical and mental health outcomes should be future research directions.

Abstract
BACKGROUND Posttraumatic Stress Disorder (PTSD) could potentially increase the risk of mortality, and there is a need for a meta-analysis to quantify this association. This study aims to determine the extent to which PTSD is a predictor of mortality. METHODS EMBASE, MEDLINE, and PsycINFO were searched systematically on 12th February 2020, with updated searches conducted in July 2021, and December 2022 (PROSPERO CRD42019142971). Studies involving community-dwelling participants with a diagnosis of PTSD or PTSD symptoms, and a comparator group of individuals without PTSD, and which assessed mortality risk, were included. A random-effects meta-analysis was conducted on studies reporting Odds Ratio (OR), Hazard Ratio (HR), and Risk Ratio (RR), and subgroup analysis was also performed by age, sex, type of trauma experienced, PTSD diagnosis, and cause of death. RESULTS A total of 30 eligible studies of mostly good methodological quality were identified, with a total of more than 2.1 million participants with PTSD. The majority of studies involved male-dominated, veteran populations. PTSD was associated with a 47% (95% CI: 1.06-2.04) greater risk of mortality across six studies that reported OR/RR, and a 32% increased risk across 18 studies which reported time to death (HR: 1.32, 95% CI: 1.10-1.59). There was very high study heterogeneity (I2 > 94%) and this was not explained by the prespecified subgroup analysis. CONCLUSION PTSD is associated with increased mortality risk, however further research is required amongst civilians, involving women, and in individuals from underdeveloped countries.

The Association of the Polymorphisms in the FUT8-Related Locus with the Plasma Glycosylation in Post-Traumatic Stress Disorder. Int J Mol Sci 2023; 24:ijms24065706. [PMID: 36982780 PMCID: PMC10056189 DOI: 10.3390/ijms24065706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 03/04/2023] [Accepted: 03/11/2023] [Indexed: 03/19/2023] Open
Abstract
The molecular underpinnings of post-traumatic stress disorder (PTSD) are still unclear due to the complex interactions of genetic, psychological, and environmental factors. Glycosylation is a common post-translational modification of proteins, and different pathophysiological states, such as inflammation, autoimmune diseases, and mental disorders including PTSD, show altered N-glycome. Fucosyltransferase 8 (FUT8) is the enzyme that catalyzes the addition of core fucose on glycoproteins, and mutations in the FUT8 gene are associated with defects in glycosylation and functional abnormalities. This is the first study that investigated the associations of plasma N-glycan levels with FUT8-related rs6573604, rs11621121, rs10483776, and rs4073416 polymorphisms and their haplotypes in 541 PTSD patients and control participants. The results demonstrated that the rs6573604 T allele was more frequent in the PTSD than in the control participants. Significant associations of plasma N-glycan levels with PTSD and FUT8-related polymorphisms were observed. We also detected associations of rs11621121 and rs10483776 polymorphisms and their haplotypes with plasma levels of specific N-glycan species in both the control and PTSD groups. In carriers of different rs6573604 and rs4073416 genotypes and alleles, differences in plasma N-glycan levels were only found in the control group. These molecular findings suggest a possible regulatory role of FUT8-related polymorphisms in glycosylation, the alternations of which could partially explain the development and clinical manifestation of PTSD.

The Interaction of Trauma Exposure and DNA Methylation on Blood Pressure Among Black Women in the InterGEN Study. Epigenet Insights 2022; 15:25168657221138510.

Abstract
Objective Despite evidence that trauma exposure is linked to higher risk of hypertension, epigenetic mechanisms (such as DNA methylation) by which trauma potentially influences hypertension risk among Black adults remain understudied. Methods Data from a longitudinal study of Black mothers were used to test the hypothesis that direct childhood trauma (ie, personal exposure) and vicarious trauma (ie, childhood trauma experienced by their children) would interact with DNA methylation to increase blood pressure (BP). Separate linear mixed effects models were fitted at each CpG site with the DNA methylation beta-value and direct and vicarious trauma as predictors and systolic and diastolic BP modeled as dependent variables adjusted for age, cigarette smoking, and body mass index. Interaction terms between DNA methylation beta-values with direct and vicarious trauma were added. Results The sample included 244 Black mothers with a mean age of 31.2 years (SD = ±5.8). Approximately 45% of participants reported at least one form of direct childhood trauma and 49% reported at least one form of vicarious trauma. Epigenome-wide interaction analyses found that no CpG sites passed the epigenome-wide significance level indicating the interaction between direct or vicarious trauma with DNAm did not influence systolic or diastolic BP. Conclusions This is one of the first studies to simultaneously examine whether direct or vicarious exposure to trauma interact with DNAm to influence BP. Although findings were null, this study highlights directions for future research that investigates epigenetic mechanisms that may link trauma exposure with hypertension risk in Black women.

Abstract
Individuals with posttraumatic stress disorder (PTSD) are at an increased risk of being classified as overweight or with obesity in part due to PTSD symptoms (e.g., sleep disturbance and social isolation) interfering with activity and healthy eating. MOVE!+UP is a 16-week behavioral weight management program, tailored to address such barriers for people with PTSD, by combining evidence-based weight loss education and support with cognitive behavior therapy skills to reduce PTSD symptom-based weight management barriers. This qualitative study examined veterans' (n = 37) perceptions of social support relevant to weight management, health behaviors, and mental health while participating in an uncontrolled pilot of MOVE!+UP. Template analysis of transcripts from 1-hr semistructured qualitative interviews identified four main categories of participant responses. Participants described positive aspects, particularly cohesiveness around a shared veteran identity, feeling less alone, accountability, and having others eat healthier and exercise with them. Conversely, relationship-based barriers included other participants' poor MOVE!+UP group session attendance and engagement, and loved ones' encouragement of making unhealthy choices. Many described having limited relationships or trouble accessing available support. Finally, PTSD symptoms were a significant barrier to utilizing social support to facilitate weight loss. Findings suggest future behavioral weight management programs should recruit members with similar backgrounds to capitalize on shared experience, encourage consistent attendance and meaningful participation, deliver education about how to leverage social support from others outside the program, and address mental health symptoms that impede social support and healthy lifestyles.

Abstract
Severe stress leads to alterations in energy metabolism with sexually dimorphic onset or severity. The locus coeruleus (LC) in the brainstem that mediates fight-or-flight-or-freeze response to stress is sexually dimorphic in morphology, plays a key role in interactions between diet and severe stressors, and has neuronal input to the brown adipose tissue (BAT)-a thermogenic organ important for energy balance. Yet, little is known on how LC coordinates stress-related metabolic adaptations. LC expresses receptors for the neuropeptide PACAP (pituitary adenylate cyclase activating peptide) and PACAP signaling through PAC1 (PACAP receptor) are critical regulators of various types of stressors and energy metabolism. We hypothesized that LC-PAC1 axis is a sex-specific central "gatekeeper" of severe acute stress-driven behavior and energy metabolism. Selective ablation of PAC1 receptors from the LC did not alter stress response in mice of either sex, but enhanced food intake in females and was associated with increased energy expenditure and BAT thermogenesis in male mice. These results show a sexually dimorphic role of the LC-PAC1 in regulating acute stress-related energy metabolism. Thus, by disrupting LC-PAC1 signaling, our studies show a unique and previously unexplored role of LC in adaptive energy metabolism in a sex-dependent manner.

Abstract
Posttraumatic stress disorder (PTSD) has long been associated with a heightened risk of cardiovascular disease (CVD). A number of mechanisms have been implicated to underlie this brain-heart axis relationship, such as altered functioning of the autonomic nervous system and increased systemic inflammation. While neural alterations have repeatedly been observed in PTSD, they are rarely considered in the PTSD-CVD link. The brain-heart axis is a pathway connecting frontal and limbic brain regions to the brainstem and periphery via the autonomic nervous system and it may be a promising model for understanding CVD risk in PTSD given its overlap with PTSD neural deficits. We first provide a summary of the primary mechanisms implicated in the association between PTSD and CVD. We then review the brain-heart axis and its relevance to PTSD, as well as findings from PTSD trials demonstrating that a number of PTSD treatments have effects on areas of the brain-heart axis. Finally, we discuss sex considerations in the PTSD-CVD link. A critical next step in this study is to determine if PTSD treatments that affect the brain-heart axis (e.g., brain stimulation that improves autonomic function) also reduce the risk of CVD.

Abstract
Background United States military Veterans from recent conflicts are experiencing symptoms related to posttraumatic stress disorder (PTSD). Many Veterans are resistant to conventional health and mental health interventions (e.g., medication, psychotherapy). Alternative treatment approaches are needed. An underlying feature of PTSD is exaggerated inflammation, both peripherally and in the central nervous system. This inflammation is thought to play an important role in the vulnerability to, aggravation of, and persistence of PTSD symptoms. Therefore, an innovative intervention strategy would be the use of immunoregulatory/anti-inflammatory probiotics to reduce inflammation. Here we describe the rationale, design, and methods of a randomized placebo-controlled trial (RCT) of Lactobacillus rhamnosus GG (LGG; ATCC 53103) for posttraumatic stress disorder (PTSD). Methods This is a Phase IIa trial of LGG for United States military Veterans with PTSD, using a longitudinal, double-blind, randomized placebo-controlled design. The primary outcome measure is plasma concentration of high-sensitivity C-reactive protein. Conclusion Despite the fact that symptoms associated with PTSD can be disabling, individuals living with this trauma-related disorder have limited options in terms of evidence-based interventions. Recent research efforts aimed at highlighting the biological mechanisms of PTSD suggest that increased inflammation and altered autonomic nervous system activity may be treatment targets, and that immunoregulatory probiotics, such as LGG, have the potential to decrease trauma-induced inflammatory responses, as well as associated symptoms. This manuscript describes the best powered human subjects Phase IIa trial, to date, of a probiotic intervention for those living with PTSD.

Associations of parental and perinatal factors with subsequent risk of stress-related disorders: a nationwide cohort study with sibling comparison. Mol Psychiatry 2022; 27:1712-1719. [PMID: 34974524 PMCID: PMC9095463 DOI: 10.1038/s41380-021-01406-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 11/16/2021] [Accepted: 11/25/2021] [Indexed: 02/05/2023]
Abstract
Little is known about the contribution of pregnancy-related parental and perinatal factors to the development of stress-related disorders. We aimed to investigate whether parental/perinatal adversities entail higher risks of stress-related disorders in the offspring, later in life, by accounting for genetic and early environmental factors. Based on the nationwide Swedish registers, we conducted a population-based cohort study of 3,435,747 singleton births (of which 2,554,235 were full siblings), born 1973-2008 and survived through the age of 5 years. Using both population- and sibling designs, we employed Cox regression to assess the association between parental and perinatal factors with subsequent risk of stress-related disorders. We identified 55,511 individuals diagnosed with stress-related disorders in the population analysis and 37,433 in the sibling analysis. In the population-based analysis we observed increased risks of stress-related disorders among offspring of maternal/paternal age <25, single mothers, parity ≥4, mothers with BMI ≥ 25 or maternal smoking in early pregnancy, gestational diabetes, and offspring born moderately preterm (GA 32-36 weeks), or small-for-gestational-age. These associations were significantly attenuated toward null in the sibling analysis. Cesarean-section was weakly associated with offspring stress-related disorders in population [hazard ratio (HR) 1.09, 95% confidence interval (CI) 1.06-1.12] and sibling analyses (HR 1.10, 95% CI 1.02-1.20). Our findings suggest that most of the observed associations between parental and perinatal factors and risk of stress-related disorders in the population analysis are driven by shared familial environment or genetics, and underscore the importance of family designs in epidemiological studies on the etiology of psychiatric disorders.

The Relationship Between Post-Traumatic Stress Disorder and Self-Management Behaviors in World Trade Center Workers with Asthma. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:242-249. [PMID: 34534721 PMCID: PMC8973280 DOI: 10.1016/j.jaip.2021.08.035] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 08/23/2021] [Accepted: 08/24/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND Comorbid posttraumatic stress disorder (PTSD) is highly prevalent and associated with increased morbidity among World Trade Center (WTC) rescue and recovery workers with asthma. However, the potential behavioral pathways underlying this relationship remain unclear. OBJECTIVE To evaluate whether PTSD is associated with lower adherence to asthma self-management behaviors among WTC workers with asthma. METHODS We used data from a prospective cohort of WTC workers with a physician diagnosis of asthma who were prescribed controller medications. Presence of comorbid PTSD was determined based on structured clinical interviews. Asthma self-management behaviors included medication adherence, inhaler technique, use of action plans, and trigger avoidance. We conducted unadjusted and multiple regression analyses to evaluate the association of PTSD with asthma self-management. RESULTS Overall, 30% of 276 WTC workers with asthma had comorbid PTSD. Posttraumatic stress disorder was associated with worse asthma control and poorer quality of life. However, PTSD was not significantly associated with medication adherence (odds ratio [OR] -0.15; 95% confidence interval [CI] -0.5 to 0.2), inhaler technique (OR -0.12; 95% CI -0.7 to 0.5), use of action plans (OR 0.8; 95% CI 0.4 to 1.8), or trigger avoidance (OR 0.9; 95% CI 0.4 to 1.8). CONCLUSIONS We did not find significant differences in key asthma self-management behaviors between WTC workers with and without PTSD. These results suggest that other mechanisms, such as differences in symptom perception or inflammatory pathways, may explain the association between PTSD and increased asthma morbidity.

Abstract
BACKGROUND Given the role of post-traumatic stress disorder (PTSD) in morbidity and mortality of cardiac patients, the present study was conducted to determine the relationship between the perception of heart disease and severity of PTSD symptoms. METHODS Sampled using simple random sampling, 202 cardiovascular patients (50.5% women) were selected and included in this cross-sectional study. The patients admitted to a hospital from January to May 2017 in western Iran were selected and asked to complete the self-report demographic and cardiac risk factors inventory, Brief Illness Perception Questionnaire (Brief-IPQ), and National Stressful Events Survey PTSD Short Scale (NSESSS) checklist. The results were analyzed using the Pearson correlation coefficient and multiple regression analysis. RESULTS The mean age of patients was 53.5 ± 11.9 years. The results of the correlation coefficient showed a significant relationship between all the components of illness perception, except personal and treatment control, with PTSD (P < 0.05). The regression model could predict 22.5% of PTSD variance and the greatest role was for the emotional representation (P = 0.002) and female sex (P = 0.008). CONCLUSION The perception of cardiovascular patients of the cognitive and emotional components of the disease, especially in women, plays a significant role in experiencing the symptoms of PTSD. Thus, health professionals have to monitor all these components, especially the patient's perceptions and emotional reactions, and to come up with proper and timely interventions for patients at risk to control the adverse effects of PTSD after cardiovascular events.

Abstract
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.

Abstract
The impact of occupational stress on first responders has received increased investigative attention in recent years. However, research specifically targeting firefighters and their unique responses to job related stress remains limited. Although cardiovascular disease (CVD) risk has been recognized in firefighters, behavioral and psychological contributions (e.g., posttraumatic stress) have not been adequately examined. The purpose of this study was to: (1) examine the relationship between posttraumatic stress symptoms and CVD risk in firefighters, (2) assess the effects of service time on the relationship, and (3) increase understanding of the manifestations of stress in this population. Participants were 87 firefighters from Special Operations teams. Self-report measures of posttraumatic stress symptoms, health, and length of service were administered. Data from annual physical examinations provided information regarding CVD risk (weight, height, blood pressure, cholesterol, smoking, physical exercise). Results indicated significant relationships between posttraumatic stress symptomatology and current smoking status, triglyceride levels, and the number of CVD risk factors. Findings suggest that the presence of posttraumatic stress symptoms may influence overall CVD risk and may not be moderated by years of fire service. Implications for behavioral interventions with firefighters are discussed. Suggestions for future research in this area are offered.

Abstract
BACKGROUND Due to ongoing political and social conflicts, the number of international refugees has been increasing. Refugees are exposed to severe mental and physical strain, as well as traumatic experiences during their flight. Therefore, the risk of psychiatric disorders is markedly increased among international refugees. International organizations have criticized the lack of early interventions as a key problem, because untreated mental disorders are often difficult to cure at a later stage. Today, exercise and sport have been successfully employed to treat a wide range of psychiatric disorders. With patients with post-traumatic stress disorders (PTSD), very limited empirical evidence exists, and studies carried out with international refugees are nearly non-existent. METHODS We intend to implement a pragmatic randomized controlled trial (RCT) with an exercise and sport intervention group (n = 68, 50% women) and a wait-list control group (n = 68, 50% women) in the Koutsochero refugee camp, located close to the city of Larissa (Greece). During the RCT, exercise and sport will be offered five times per week (60 min/session) for 10 weeks. Participants will be asked to participate in at least two sessions per week. The programme is developed according to the participants' needs and preferences and they will be able to choose between a range of activities. PTSD symptoms will serve as primary outcome, and several secondary outcomes will be assessed. Qualitative data collection methods will be used to gain a more in-depth appraisal of the participants' perception of the intervention programme. In the second year of study, the programme will be opened to all camp residents. A strategy will be developed how the programme can be continued after the end of the funding period, and how the programme can be scaled up beyond the borders of the Koutsochero camp. DISCUSSION By moving towards the primary prevention of chronic physical conditions and psychiatric disorders, a relevant contribution can be done to enhance the quality and quantity of life of refugee camp residents in Greece. Our findings may also strengthen the evidence for exercise as medicine as a holistic care option in refugee camps, by helping camp residents to adopt and maintain a physically active lifestyle. TRIAL REGISTRATION The study was registered prospectively on the 8 February 2021 with ISRCTN https://www.isrctn.com/ISRCTN16291983.

Abstract
Patient reports of moderate to severe pain are common across the spectrum of chronic kidney disease. The synergistic effects of comorbid depression and anxiety can lead to maladaptive coping responses to pain, namely pain catastrophizing and illness-related post-traumatic stress disorder. If underlying depression and anxiety and associated maladaptive coping responses are not treated, patients can experience an increased perception of pain, worsened disability, decreased quality of life, withdrawal from social activities, and increased morbidity and mortality. Meanwhile, interest in nonpharmacologic treatments for pain that targets coping as well as comorbid anxiety and depression has been increasing, particularly given the significant societal damage that has resulted from the opioid epidemic. Evidence-based, nonpharmacologic treatments have shown promise in treating pain in areas outside of nephrology. Currently, little is known about the effects of these treatments among adults with CKD, and particularly end-stage kidney disease, when chronic pain can become debilitating. In this review, we examine patient-centered concepts related to pain that have received little attention in the nephrology literature. We also describe emerging areas of research, including omics technologies for biomarker discovery and advanced symptom clustering methods for symptom phenotyping, which may be useful to future kidney disease research and treatment.

Abstract
OBJECTIVE High levels of psychological distress increase the risk of a wide range of medical diseases. In this study, we investigated the association between posttraumatic stress disorder (PTSD) and kidney disease. METHODS World Trade Center (WTC) responders were included if they had two or more measures of estimated glomerular filtration rate (eGFR). The PTSD Checklist (PCL) was used to define no PTSD (PCL < 40), "mild" PTSD (40 ≤ PCL <50), and "severe" PTSD (PCL ≥50). Subtypes of PTSD by symptom clusters were analyzed. Multinomial logistic regression was used to estimate the association of PTSD with two GFR change outcomes (decline or increase) compared with the stable GFR outcome. RESULTS In 2266 participants, the mean age was 53.1 years, 8.2% were female, and 89.1% were White. Individuals with PTSD (n = 373; 16.5%) did not differ in mean baseline GFR from individuals without PTSD (89.73 versus 90.56 mL min-1 1.73 m-2; p = .29). During a 2.01-year mean follow-up, a mean GFR decline of -1.51 mL min-1 1.73 m-2 per year was noted. In multivariable-adjusted models, PTSD was associated with GFR decline (adjusted relative risk [aRR] = 1.74 [1.32-2.30], p < .001) compared with stable GFR, with "hyperarousal" symptoms showing the strongest association (aRR =2.11 [1.40-3.19]; p < .001). Dose-response effects were evident when comparing mild with severe PTSD and comparing PTSD with versus without depression. PTSD was also associated with GFR rise (aRR = 1.47 [1.10-1.97], p < .009). The association between PTSD and GFR change was stronger in participants older than 50 years. CONCLUSIONS PTSD may be a novel risk factor for exaggerated longitudinal GFR change in young, healthy adults. These findings need to be validated in other cohorts.

Abstract
RATIONALE Childhood adversity, which is related to negative cognitive consequences, is highly prevalent across the world. Nonetheless, there is still a scarcity of research on late-life cognitive function that accounted for multiple aspects of adverse events as well as the potential mediating mechanism of social context and individual's wellbeing in adulthood. OBJECTIVE This study aimed to investigate the relationship between childhood adversities and late-life cognitive function among the middle-aged and older Chinese population and to determine the mediating role of education attainment, marital status, financial status, and self-rated health in adulthood. METHODS We used three waves of data from China Health and Retirement Longitudinal Study from 2011 to 2015, which consisted of 23 807 participants aged 45 years and older. Generalized Estimating Equation and Structural Equation Model were applied to examine the association between childhood adversities and cognitive function (mental intactness and episodic memory) and the corresponding potential mechanisms. RESULTS Overall, 77.25%, 64.55%, 38.38%, and 15.03% of respondents experienced socioeconomic disadvantage, parental involved trauma, maladaptive parental trauma, and other trauma in childhood, respectively. Multivariate analyses suggest that all four types of childhood adversities were associated with a lower score of mental intactness and the first three were associated with episodic memory. A large proportion of the associations between childhood adversity and cognitive function was mainly mediated by education attainment, self-rated health and marital status in adulthood. CONCLUSION There are negative linkages between childhood adversities and cognitive function in the middle-aged and older Chinese population. Such associations were primarily functioning indirectly through adult social context and health conditions.

Abstract
OBJECTIVES To evaluate feasibility and acceptability of a group-based nature recreation intervention (nature hiking) and control condition (urban hiking) for military Veterans with post-traumatic stress disorder (PTSD). DESIGN AND SETTING A pilot randomised controlled trial conducted in the US Pacific Northwest. PARTICIPANTS Veterans with PTSD due to any cause. INTERVENTIONS Twenty-six participants were randomised to a 12-week intervention involving either six nature hikes (n=13) or six urban hikes (n=13). PRIMARY AND SECONDARY OUTCOME MEASURES Feasibility was assessed based on recruitment, retention and attendance. Questionnaires and postintervention qualitative interviews were conducted to explore intervention acceptability. Questionnaires assessing acceptability and outcomes planned for the future trial (eg, PTSD symptoms) were collected at baseline, 6 weeks, 12 weeks (immediately after the final hike) and 24 weeks follow-up. RESULTS Of 415 people assessed for eligibility/interest, 97 were interested and passed preliminary eligibility screening, and 26 were randomised. Mean completion of all questionnaires was 91% among those in the nature hiking group and 68% in those in the urban hiking group. Over the course of the intervention, participants in the nature and urban groups attended an average of 56% and 58%, respectively, of scheduled hikes. Acceptability of both urban and nature hikes was high; over 70% reported a positive rating (ie, good/excellent) for the study communication, as well as hike locations, distance and pace. Median PTSD symptom scores (PTSD Checklist-5) improved more at 12 weeks and 24 weeks among those in the nature versus urban hiking group. CONCLUSIONS This pilot study largely confirmed the feasibility and acceptability of nature hiking as a potential treatment for Veterans with PTSD. Adaptations will be needed to improve recruitment and increase hike attendance for a future randomised controlled trial to effectively test and isolate the ways in which nature contact, physical activity and social support conferred by the group impact outcomes. TRIAL REGISTRATION NUMBER NCT03997344.

Abstract
BACKGROUND Hypertension is a major preventable risk factor for cardiovascular disease. Occupational factors such as having served or serving in armed forces may be associated with hypertension. This study aimed to assess the prevalence and factors associated with hypertension among veterans of the Indian Gorkha army living in western Nepal. METHODS A community-based cross-sectional study was conducted among the veterans living in the Pokhara metropolitan city. Data on blood pressure (BP), anthropometric measurements, and behavioral factors were collected by face-to-face interviews using the World Health Organization's non-communicable disease risk factor surveillance (STEPS) tool. Hypertension was defined as systolic blood pressure (BP) ≥ 140 mm Hg and/or diastolic BP of ≥ 90 mm Hg or currently on antihypertensive medication. RESULTS The age-adjusted prevalence of hypertension was 66.2 % among the study participants (317). Mean systolic and diastolic blood pressure was 144.5 mmHg (± 18.3) and 89.3mmHg (± 16.0), respectively. Among the hypertensive participants, 67 % were aware of their disease, 90 % of them were under treatment, and 14 % of the individuals who received treatment had their hypertension under control. The proportion of smokers was 12.9 % and alcohol drinker was 86.1 %. One-fourth (25.9 %) of the participants had a family history of hypertension. Veterans aged 55-64 years had higher odds (AOR: 5.3; 95 % CI: 1.8-15.9; p = 0.003) of being associated with hypertension as compared to 35-44 years. Being a current alcohol drinker (AOR: 2.5; 95 % CI: 1.4-4.5; p = 0.003), overweight (AOR: 1.9; 95 % CI: 1.0-3.5; p = 0.04), obese (AOR: 3.1; 95 % CI: 1.1-8.3; p = 0.03) and family history of hypertension (AOR: 2.9; 95 % CI: 1.5-5.8; p = 0.002) were independently associated with hypertension. CONCLUSIONS Hypertension was prevalent in retired Nepal veterans. Hypertension was associated with a number of modifiable lifestyle and behavioral factors. Our findings suggest the need for screening, education and management of Nepal veterans for hypertension.

[PMID: 34144246 DOI: 10.1016/j.cct.2021.106487] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 06/10/2021] [Accepted: 06/11/2021] [Indexed: 10/21/2022]
Abstract
Post-traumatic stress disorder (PTSD), prevalent among Veterans, increases risk for having a high Body Mass Index. Although the Veterans Health Administration (VHA) offers an evidence-based behavioral weight management program called MOVE!, participants with PTSD lose less weight than those without mental health conditions, despite comparable participation. PTSD symptoms can interfere with one's ability to be physically active and maintain a healthy diet, the key targets in weight management programs. We developed and piloted a behavioral weight management program called MOVE! + UP that targets PTSD-related weight loss barriers. MOVE! + UP includes 16 group sessions with training in evidence-based weight management strategies, coupled with Cognitive Behavior Therapy (CBT) skills to address PTSD-specific barriers. The 16 sessions also include 30-min community walks to address PTSD-related barriers that may impede exercise. Two individual dietician sessions are provided. This hybrid type 1 randomized controlled trial (RCT) will compare MOVE! + UP to standard care-MOVE!-among 164 Veterans with BMI ≥ 25 who are receiving care for PTSD. We will randomize participants to MOVE! + UP or standard care and will compare absolute post-baseline change in weight at 6 (primary outcome) and 12 (secondary outcome) months, and PTSD symptom severity at 6 and 12 months (secondary outcome). Exploratory analyses will compare the treatment conditions on treatment targets measured at 6 months (e.g., physical activity, eating behavior, social support). Finally, we will estimate intervention costs, and identify MOVE! + UP implementation barriers and facilitators. If effective, MOVE! + UP could be an efficient way to simultaneously address physical and mental health for Veterans with PTSD.

Abstract
OBJECTIVE Older veterans with post-traumatic stress disorder (PTSD) experience substantial physical and mental health challenges. Given the well-known and wide-reaching benefits of exercise, exploring the impact of interventions designed specifically for this population would be valuable. As such, the present study explored perspectives from older veterans with PTSD who participated in Warrior Wellness, a 12-week supervised exercise intervention designed for older veterans with PTSD. This study was aimed at evaluating 1) facilitators of engagement, 2) perceived benefits from the intervention, and 3) recommendations about possible modifications to the intervention. DESIGN Qualitative study. SETTING Face-to-face semistructured interviews conducted after the Warrior Wellness trial was completed. PARTICIPANTS Fifteen veterans (100% male, 93% African American or Black, 100% non-Hispanic or Latinx, average age = 68.7 years) who completed the Warrior Wellness exercise program. MEASUREMENTS Semistructured interviews were conducted using an interview guide that assessed veterans' experience in Warrior Wellness and recommendations for future intervention modifications. Interviews were subsequently transcribed and analyzed by thematic analysis. RESULTS Shared experience, program features, camaraderie during workouts, and accountability emerged as facilitators of engagement. Perceived benefits spanned physical health, mental health, and behavioral domains. Finally, veterans provided several suggestions for modifying the intervention such as increasing its duration, adding a nutritional component, and including significant others in enrollment. CONCLUSIONS This study offers valuable insights into the intervention and interpersonal factors that veterans view as important for their engagement in exercise, the perceived benefits of exercise, and the ways in which interventions designed for this population can be refined.

Abstract
OBJECTIVES To evaluate the diagnostic accuracy of the Impact Event Scale-Revisited assessed following ICU discharge to predict the emergence of post-traumatic stress disorder symptoms at 3 months. DESIGN Prospective cohort study. SETTING Three medical or surgical ICU of a French university hospital (Lyon, France). PATIENTS Patients greater than or equal to 18 years old, leaving ICU after greater than or equal to 2 nights of stay, between September 2017 and April 2018. INTERVENTIONS Patients completed the Impact Event Scale-Revisited and the Peritraumatic Dissociative Experiences Questionnaire within 8 days after ICU discharge and the Impact Event Scale-Revisited again at 3 months by phone. Patients having an Impact Event Scale-Revisited greater than or equal to 35 at 3 months were considered as having post-traumatic stress disorder symptoms. MEASUREMENTS AND MAIN RESULTS Among the 208 patients screened, 174 were included and 145 reassessed by phone at 3 months. Among the patients included at baseline, 43% presented symptoms of acute stress. At 3 months, 13% had an Impact Event Scale-Revisited greater than or equal to 35 and 17% had a score between 12 and 34. Regarding the performance of the Impact Event Scale-Revisited performed within 8 days after the ICU discharge to predict post-traumatic stress disorder symptoms at 3 months, the area under the curve was 0.90 (95% CI, 0.80-0.99), and an Impact Event Scale-Revisited greater than or equal to 12 had a sensitivity of 90%, a specificity of 71%, a positive predictive value of 32%, and a negative predictive value of 98%. History of anxiety disorder odds ratio = 3.7 (95% CI, 1.24-11.05; p = 0.02) and Impact Event Scale-Revisited greater than or equal to 12 odds ratio = 16.57 (95% CI, 3.59-76.46; p < 0.001) were identified as risk factors for post-traumatic stress disorder symptoms. CONCLUSIONS Impact Event Scale-Revisited assessed at ICU discharge has a good ability for the detection of patients at risk of developing post-traumatic stress disorder symptoms. Patients with history of anxiety disorder and those presenting acute stress symptoms at ICU discharge are more at risk to develop post-traumatic stress disorder symptoms.

Abstract
After a massive disaster, many residents in affected areas are forced to temporarily stay in evacuation shelters. The exact impact of the state of resource supply and infrastructure in evacuation shelters on the health status of evacuees has not been sufficiently studied. Two weeks after the 2011 Great East Japan Earthquake (GEJE), comprehensive surveillance related to the health status and hygiene level was performed for all evacuation shelters (328 shelters with 46,480 evacuees at the peak) in one of the most devastating medical zones after the tsunami hit the area (Ishinomaki City). The joint relief team regularly visited all evacuation shelters across the area to assess the situation of resource supply levels, infrastructural damage, rapid need of resources, and the health status of the evacuees. In this cross-sectional observational study, we evaluated the relationship between the resource supply levels and health status among evacuees in two time periods (days 14-19 and 20-25). Among the evaluated vital resources, clean tap water supply was among the most disrupted by the disaster, and was not fully restored in most shelters during the assessment period. The cross-sectional relationship between resource supplies and morbidity was inconsistent between the two assessment periods, reflecting the multifactorial nature of health status in evacuation shelters. The clean tap water supply level at the first assessment showed a strong negative correlation with the subsequent prevalence of respiratory or gastrointestinal infectious conditions at the second assessment. Restorations in the clean tap water supply and toilet hygiene correlated each other, and both correlated with a decrease in the prevalence of gastrointestinal infectious conditions. In conclusion, disrupted clean tap water supply and inadequate toilet hygiene after a massive disaster would jointly harm the health status of those in shelters. Prompt assessments using quick visual assessment and restorations of these key resources have validity with suppressed environmental health risks among evacuees.

Abstract
OBJECTIVE Post-traumatic stress disorder (PTSD) is common in Veterans. Symptoms can perpetuate into late life, negatively impacting physical and mental health. Exercise and social support are beneficial in treating anxiety disorders such as PTSD in the general population, although less is known about the impact on Veterans who have lived with PTSD for decades. This study assessed associations between social connectedness, physical function and self-reported change in PTSD symptoms among older Veterans specifically participating in Gerofit. DESIGN Prospective clinical intervention. SETTING Twelve sites of Veterans Affairs (VA) Gerofit exercise program across the United States. PARTICIPANTS Three hundred and twenty one older Veteran Gerofit participants (mean age = 74) completed physical assessments and questionnaires regarding physical and emotional symptoms and their experience. MEASUREMENTS Measures of physical function, including 30-second chair stands, 10-m and 6-min walk were assessed at baseline and 3 months; change in PTSD symptoms based on the Diagnostic Statistical Manual-5 (DSM-5) assessed by a self-report questionnaire; and social connection measured by the Relatedness Subscale of the Psychological Need Satisfaction in Exercise scale (PNSE) were evaluated after 3 months of participation in Gerofit. RESULTS Ninety five (29.6%) Veterans reported PTSD. Significant improvement was noted in self-rated PTSD symptoms at 3 months (P < .05). Moderate correlation (r = .44) was found between social connectedness with other participants in Gerofit and PTSD symptom improvement for those Veterans who endorsed improvement (n = 59). All participants improved on measures of physical function. In Veterans who endorsed PTSD there were no significant associations between physical function improvement and PTSD symptoms. CONCLUSION Veterans with PTSD that participated in Gerofit group exercise reported symptom improvement, and social connectedness was significantly associated with this improvement. In addition to physical health benefits, the social context of Gerofit may offer a potential resource for improving PTSD symptoms in older Veterans that warrants further study.

Low Dose Ketamine Infusion for Comorbid Posttraumatic Stress Disorder and Chronic Pain: A Randomized Double-Blind Clinical Trial. ACTA ACUST UNITED AC 2020; 4:2470547020981670. [PMID: 33426410 PMCID: PMC7758557 DOI: 10.1177/2470547020981670] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 11/24/2020] [Indexed: 11/15/2022]
Abstract
Objective To date, treatment options (i.e. psychotherapy, antidepressant medications) for patients with posttraumatic stress disorder (PTSD), are relatively few, and considering their limited efficacy, novel therapies have gained interest among researchers and treatment providers alike. Among patients with chronic pain (CP) about one third experience comorbid PTSD, which further complicates their already challenging pharmacological regimens. Low dose ketamine infusion has shown promise in PTSD, and in treatment of CP, however they have not been studied in comorbid population and under rigorous control conditions. Methods We compared the effects of a single dose of either ketamine (0.5 mg/kg) or ketorolac (15 mg) over a 40-minute of IV infusion in CP patients with and without PTSD, in double blind, randomized study. Measures were collected before, during, one day and seven days after the infusion. A planned sample size of 40 patients randomly assigned to treatment order was estimated to provide 80% power to detect a hypothesized treatment difference after the infusion. Main Outcome and Measures: The primary outcome measures were change in PTSD symptom severity assessed with the Impact of Event Scale–Revised (IES-R) and Visual Analogue Scale (VAS) for pain administered by a study clinician 24 hours post infusion. Secondary outcome measures included Impact of Event Scale–Revised (IES-R), VAS and Brief Pain Inventory (Short Form) for pain 1 week after the infusion. Results Both treatments offered comparable improvement of PTSD and CP symptoms that persisted for 7 days after the infusion. Patients with comorbid PTSD and CP experienced less dissociative side effects compared to the CP group. Surprisingly, ketorolac infusion resulted in dissociative symptoms in CP patients only. Conclusions This first prospective study comparing effects of subanesthetic ketamine versus ketorolac infusions for comorbid PTSD and CP, suggests that both ketamine and ketorolac might offer meaningful and durable response for both PTSD and CP symptoms.

Abstract
Background: Internationally deployed humanitarian aid (HA) workers are routinely confronted with potentially traumatic stressors. However, it remains unknown whether HA deployment and related traumatic stress are associated with long-term changes in hypothalamic-pituitary-adrenal (HPA) axis function. Therefore, we investigated whether cortisol awakening response (CAR) decreased upon deployment and whether this was moderated by previous and recent trauma exposure and parallel changes in symptom severity and perceived social support. Methods: In this prospective study, n = 86 HA workers (68% females) completed questionnaires regarding trauma exposure, posttraumatic stress disorder (PTSD), anxiety and depressive symptoms and perceived social support, as well as salivary cortisol assessments at awakening and 30 minutes post-awakening at before, early and 3-6 months post-deployment. Results: Linear mixed models showed significantly decreased CAR (b(SE) = -.036(.011), p = .002) and awakening cortisol over time (b(SE) = -.007(.003), p = .014). The extent of awakening cortisol change was significantly moderated by interactions between previous and recent trauma exposure. Also, a steeper awakening cortisol decrease was significantly associated with higher mean anxiety and PTSD symptoms across assessments. No significant effects were found for social support. Conclusions: We observed attenuated CAR and awakening cortisol upon HA deployment, with a dose-response effect between trauma exposure before and during the recent deployment on awakening cortisol. Awakening cortisol change was associated with PTSD and anxiety symptom levels across assessments. Our findings support the need for organizational awareness that work-related exposures may have long-lasting biological effects. Further research assessing symptoms and biological measures in parallel is needed to translate current findings into guidelines on the individual level.

Abstract
Importance Consistent evidence has found associations between posttraumatic stress disorder (PTSD) and increased risk of chronic disease and greater prevalence of health risk factors. However, the association between PTSD and all-cause mortality has not been thoroughly investigated in civilians. Objective To investigate the association between PTSD symptoms, with or without comorbid depressive symptoms, and risk of death. Design, Setting, and Participants This prospective cohort study was conducted using data on female US nurses in the Nurses' Health Study II followed up from 2008 to 2017. Women who responded to a 2008 questionnaire querying PTSD and depressive symptoms were included. Data were analyzed from September 2018 to November 2020. Exposures Symptoms of PTSD, measured using the short screening scale for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) PTSD, and depression symptoms, measured using the Center for Epidemiologic Studies Depression Scale-10 in 2008. Main Outcomes and Measures All-cause mortality was determined via National Death Index, US Postal Service, or report of participant's family. The hypothesis being tested was formulated after data collection. Trauma exposure and PTSD symptoms were jointly coded as no trauma exposure (reference), trauma and no PTSD symptoms, 1 to 3 PTSD symptoms (subclinical), 4 to 5 PTSD symptoms (moderate), and 6 to 7 PTSD symptoms (high). Results Among 51 602 women (50 137 [97.2%] White individuals), the mean (range) age was 53.3 (43-64) years at study baseline in 2008. PTSD and probable depression were comorbid; of 4019 women with high PTSD symptoms, 2093 women (52.1%) had probable depression, while of 10 105 women with no trauma exposure, 1215 women (12.0%) had probable depression. Women with high PTSD symptoms and probable depression were at nearly 4-fold greater risk of death compared with women with no trauma exposure and no depression (hazard ratio [HR], 3.80; 95% CI, 2.65-5.45; P < .001). After adjustment for health factors, women with these conditions had a more than 3-fold increased risk (HR, 3.11; 95% CI, 2.16-4.47, P < .001). Women with subclinical PTSD symptoms without probable depression had increased risk of death compared with women with no trauma exposure and no depression (HR, 1.43; 95% CI, 1.06-1.93; P = .02). Among 7565 women with PTSD symptoms and probable depression, 109 deaths (1.4%) occurred for which we obtained cause of death information, compared with 124 such deaths (0.6% ) among 22 215 women with no depression or PTSD symptoms. Women with PTSD symptoms and probable depression, compared with women with no PTSD or depression, had higher rates of death from cardiovascular disease (17 women [0.22%] vs 11 women [0.05%]; P < .001), diabetes (4 women [0.05%] vs 0 women; P < .001), unintentional injury (7 women [0.09%] vs 7 women [0.03%]; P = .03), suicide (9 women [0.12%] vs 1 woman [<0.01%]; P < .001), and other causes of death (14 women [0.19%] vs 17 women [0.08%]; P = .01). Conclusions and Relevance These findings suggest that at midlife, women with high PTSD symptoms and co-occurring probable depression are at increased risk of death compared with women without these disorders. Treatment of PTSD and depression in women with symptoms of both disorders and efforts to improve their health behaviors may reduce their increased risk of mortality.

Abstract
Populations in the global south are disproportionately exposed to the stressors of development, disaster and armed conflict, all of which heighten cardiovascular disease (CVD) risk. We consider how war-related stressors exert a lasting influence upon population health, in particular the cardiovascular health of war survivors now entering older adulthood. Data come from the 2018 Vietnam Health and Aging Study conducted among 2447 northern Vietnamese adults age 60 and older. We conduct survey-adjusted logistic regression analyses to examine the associations among respondents' wartime exposure to combat and physical threat, malevolent environment conditions, and four CVD conditions (hypertension, dyslipidemia, heart disease, and stroke). We examine posttraumatic stress disorder (PTSD) as it mediates the association between wartime stress exposures and late life CVD, and gender as it moderates the relationship between wartime stressors and CVD. We find that exposure to wartime combat and violence, as well as malevolent living conditions, exhibit significant, positive associations with cardiovascular conditions. These associations are mediated by the severity of recent PTSD symptoms. For certain CVD conditions, particularly hypertension, the associations between wartime stressors and late life cardiovascular conditions diverge across gender with women experiencing a greater penalty for their exposure to war-related stressors than their male counterparts. We conclude that the stressors of war and resultant PTSD, widespread in this cohort of Vietnamese older adults who endured myriad forms of war exposure during their young adulthood, exhibit modest, yet significant associations with late-life cardiovascular conditions. Women, especially those exposed to wartime violence and combat, bear this CVD burden alongside men.

Abstract
Abstract
Background
Military veterans living with post-traumatic stress disorder (PTSD) face significant physical and functional health disparities, which are often aggravated over time and in the context aging. Evidence has shown that physical activity can positively impact age-related health conditions, yet exercise trials in older adults with mental disorders are rare. Our study was a tailored and targeted pilot exercise intervention for older veterans with PTSD.
Methods
Fifty-four older veterans with PTSD (mean age = 67.4 years, 90.7% male, 85.2% non-white) were randomized to supervised exercise (n = 38) or wait-list usual care (n = 18) for 12 weeks. Physical activity (MET-min/wk) and aerobic endurance (assessed with the 6-minute walk test) were primary outcomes. Secondary outcomes were physical performance (strength, mobility, balance), cardiometabolic risk factors (eg, waist circumference), and health-related quality of life.
Results
At 12 weeks, a large effect of the intervention on physical activity levels (Cohen’s d = 1.37) was observed compared to wait-list usual care. Aerobic endurance improved by 69 m in the exercise group compared to 10 m in wait-list group, reflecting a moderate between-group effect (Cohen’s d = 0.50). Between-group differences on 12-week changes in physical performance, cardiometabolic risk factors, and health-related quality of life ranged from small to large effects (Cohen’s d = 0.28–1.48), favoring the exercise arm.
Conclusion
Participation in supervised exercise improved aerobic endurance, physical performance, and health-related clinical factors in older veterans with PTSD; a medically complex population with multiple morbidity. Group exercise is a low-cost, low-stigma intervention, and implementation efforts among older veterans with PTSD warrants further consideration.

Abstract
BACKGROUND Chronic posttraumatic stress disorder (PTSD) is a disabling condition that generates considerable morbidity, mortality, and both medical and indirect social costs. Treatment options are limited. A novel therapy using 3,4-methylenedioxymethamphetamine (MDMA) has shown efficacy in six phase 2 trials. Its cost-effectiveness is unknown. METHODS AND FINDINGS To assess the cost-effectiveness of MDMA-assisted psychotherapy (MAP) from the health care payer's perspective, we constructed a decision-analytic Markov model to portray the costs and health benefits of treating patients with chronic, severe, or extreme, treatment-resistant PTSD with MAP. In six double-blind phase 2 trials, MAP consisted of a mean of 2.5 90-minute trauma-focused psychotherapy sessions before two 8-hour sessions with MDMA (mean dose of 125 mg), followed by a mean of 3.5 integration sessions for each active session. The control group received an inactive placebo or 25-40 mg. of MDMA, and otherwise followed the same regimen. Our model calculates net medical costs, mortality, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios. Efficacy was based on the pooled results of six randomized controlled phase 2 trials with 105 subjects; and a four-year follow-up of 19 subjects. Other inputs were based on published literature and on assumptions when data were unavailable. We modeled results over a 30-year analytic horizon and conducted extensive sensitivity analyses. Our model calculates expected medical costs, mortality, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio. Future costs and QALYs were discounted at 3% per year. For 1,000 individuals, MAP generates discounted net savings of $103.2 million over 30 years while accruing 5,553 discounted QALYs, compared to continued standard of care. MAP breaks even on cost at 3.1 years while delivering 918 QALYs. Making the conservative assumption that benefits cease after one year, MAP would accrue net costs of $7.6 million while generating 288 QALYS, or $26,427 per QALY gained. CONCLUSION MAP provided to patients with severe or extreme, chronic PTSD appears to be cost-saving while delivering substantial clinical benefit. Third-party payers are likely to save money within three years by covering this form of therapy.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of death in the United States and the leading cause of hospitalization and disability among the US veterans. Information about CVD knowledge and risk factors, and connection between psychological health and CVD among veterans transitioning from the military are limited. PURPOSE We examined the existing knowledge of CVD and its risk factors among the US veterans with and without post-traumatic stress disorder (PTSD), and the relationship between knowledge, risk factors, resilience, and PTSD. METHODS A total of 104 veterans participated in our study by responding to the Primary Care PTSD Screen for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Heart Disease Fact Questionnaire (HDFQ) knowledge scale, and Connor-Davidson Resilience Scale 10. Data were extracted from the online Qualtrics survey software into SPSS (v. 25) for analysis. RESULTS Mean age was 52.3 years, mostly males (85.6%), married (72.1%), employed (54.8%), and with college education. Most were in the Navy or Air Force (72.1%) and served in a war (68.0%). Hypertension, high cholesterol, and obesity were the most common CVD risk factors reported. Average CVD knowledge score was 85%. Marines scored higher on resilience than other branches of the military. Seventeen percent reported having PTSD. The Connor-Davidson Resilience Scale 10 was significantly correlated with the HDFQ in the probable PTSD group (r = .589, p = .013). IMPLICATIONS FOR PRACTICE Our study provides information about the knowledge and risk factors of CVD among veterans and insights about interventions needed to improve CV health. Nurse practitioners should assess the CV and psychological health of veterans and screen for PTSD to provide appropriate care and referral.

Abstract
Natural disasters have negative health impacts on chronic diseases in affected populations. Severely affected areas are usually rural areas with limited basic infrastructure and a population have that has limited access to optimal healthcare after a disaster. Patients with cardiovascular diseases are required to maintain quality care, especially after disasters. A population-based case-control study enrolled adults from the National Health Insurance Registry who had ischemic heart disease and cerebrovascular disease histories and lived in the area affected by Typhoon Morakot in 2009. Monthly medical visits for acute cerebrovascular and ischemic heart diseases markedly increased at approximately 1–2 months after the typhoon. Survival analysis during the two years following the typhoon indicated a significant increase in mortality in adults with an acute ischemic heart disease history who lived in the severely affected area. Mortality hazard analysis showed that among affected adults with previous cerebrovascular diseases and acute ischemic heart diseases, patients with diabetes (adjusted hazard ratio [HR]: 1.3–1.7), Chronic Kidney Disease (CKD) (adjusted HR: 2.0–2.7), chronic obstructive pulmonary diseases (COPD) and asthma (adjusted HR: 1.7–2.1), liver cirrhosis (adjusted HR: 2.3–3.3) and neoplasms (adjusted HR: 1.1–2.1) had significantly increased mortality rates. Consequently, high-quality and accessible primary healthcare plans should be made available to maintain and support affected populations after disasters.

Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) is a public health concern that may elevate the risk for cardiovascular disease (CVD). There are established sex differences in both PTSD risk and CVD risk. PURPOSE To examine sex-specific associations between subclinical PTSD symptom severity and subclinical CVD risk in young men and women. METHODS A total of 61 young adults (women: n = 29, mean age: 26 ± 7 years) completed the post-traumatic stress disorder civilian checklist (PCL) and the Center for Epidemiologic Studies Depression Scale (CES-D). Aortic stiffness was measured as carotid-femoral pulse wave velocity (cfPWV). Peripheral vasomotor function was measured as flow-mediated slowing (FMS) of carotid-radial PWV following 5-min forearm occlusion. Heart rate variability was used to assess sympathovagal balance as LF/HF ratio. RESULTS PCL score was positively correlated with CES-D score (r = 0.79, p < .001), cfPWV (r = 0.33, p = .03) and LF/HF ratio (r = 0.42, p = .009) in men. PCL score was positively correlated to CES-D score (r = 0.80, p < .001) in women, but was inversely correlated to cfPWV (r = -0.38, p = .02) and LF/HF ratio (r = -0.34, p = .04). PCL score was also inversely associated with FMS in women (r = -0.49, p = .01). CONCLUSION There are sex differences in the association of PTSD symptoms and subclinical atherosclerosis. In men, increased PTSD symptoms may increase CVD risk by increasing sympathovagal balance and aortic stiffness. In women, increased PTSD symptoms may increase CVD risk via reducing vasomotor function.

Abstract
Co-morbidity between medical and psychiatric conditions is commonly considered between individual pairs of conditions. However, an important alternative is to consider all conditions as part of a co-morbidity network, which encompasses all interactions between patients and a healthcare system. Analysis of co-morbidity networks could detect and quantify general tendencies not observed by smaller-scale studies. Here, we investigate the co-morbidity network derived from longitudinal healthcare records from approximately 1 million United States military veterans, a population disproportionately impacted by psychiatric morbidity and psychological trauma. Network analyses revealed marked and heterogenous patterns of co-morbidity, including a multi-scale community structure composed of groups of commonly co-morbid conditions. Psychiatric conditions including posttraumatic stress disorder were strong predictors of future medical morbidity. Neurological conditions and conditions associated with chronic pain were particularly highly co-morbid with psychiatric conditions. Across conditions, the degree of co-morbidity was positively associated with mortality. Co-morbidity was modified by biological sex and could be used to predict future diagnostic status, with out-of-sample prediction accuracy of 90-92%. Understanding complex patterns of disease co-morbidity has the potential to lead to improved designs of systems of care and the development of targeted interventions that consider the broader context of mental and physical health.

Abstract
Despite pre-clinical evidence for the role of inflammation in traumatic brain injury (TBI), there is limited data on inflammatory biomarkers in mild TBI (mTBI). In this study, we describe the profile of plasma inflammatory cytokines and explore associations between these cytokines and neuropsychological outcomes after mTBI. Patients with mTBI with negative computed tomography and orthopedic injury (OI) controls without mTBI were prospectively recruited from emergency rooms at three trauma centers. Plasma inflammatory cytokine levels were measured from venous whole-blood samples that were collected at enrollment (within 24 h of injury) and at 6 months after injury. Neuropsychological tests were performed at 1 week, 1 month, 3 months, and 6 months after the injury. Multivariate regression analysis was performed to identify associations between inflammatory cytokines and neuropsychological outcomes. A total of 53 mTBI and 24 OI controls were included in this study. The majority of patients were male (62.3%), and injured in motor vehicle accidents (37.7%). Plasma interleukin (IL)-2 (p = 0.01) and IL-6 (p = 0.01) within 24 h post-injury were significantly higher for mTBI patients compared with OI controls. Elevated plasma IL-2 at 24 h was associated with more severe 1-week post-concussive symptoms (p = 0.001). At 6 months, elevated plasma IL-10 was associated with greater depression scores (p = 0.004) and more severe post-traumatic stress disorder (PTSD) symptoms (p = 0.001). Plasma cytokine levels (within 24 h and at 6 months post-injury) were significantly associated with early and late post-concussive symptoms, PTSD, and depression scores after mTBI. These results highlight the potential role of inflammation in the pathophysiology of post-traumatic symptoms after mTBI.

Abstract
Innate and adaptive immune mechanisms have emerged as critical regulators of CNS homeostasis and mental health. A plethora of immunologic factors have been reported to interact with emotion- and behavior-related neuronal circuits, modulating susceptibility and resilience to mental disorders. However, it remains unclear whether immune dysregulation is a cardinal causal factor or an outcome of the pathologies associated with mental disorders. Emerging variations in immune regulatory pathways based on sex differences provide an additional framework for discussion in these psychiatric disorders. In this review, we present the current literature pertaining to the effects that disrupted immune pathways have in mental disorder pathophysiology, including immune dysregulation in CNS and periphery, microglial activation, and disturbances of the blood-brain barrier. In addition, we present the suggested origins of such immune dysregulation and discuss the gender and sex influence of the neuroimmune substrates that contribute to mental disorders. The findings challenge the conventional view of these disorders and open the window to a diverse spectrum of innovative therapeutic targets that focus on the immune-specific pathophenotypes in neuronal circuits and behavior. SIGNIFICANCE STATEMENT: The involvement of gender-dependent inflammatory mechanisms on the development of mental pathologies is gaining momentum. This review addresses these novel factors and presents the accumulating evidence introducing microglia and proinflammatory elements as critical components and potential targets for the treatment of mental disorders.

Abstract
Heart rate variability (HRV) associated with parasympathetic activity (i.e., cardiac vagal tone) is reduced in posttraumatic stress disorder (PTSD), but possible confounding effects of respiration have not been studied sufficiently. Further, reduced parasympathetic inhibition might contribute to elevated heart rate (HR) in PTSD. Finally, reduced HRV in PTSD might extend to intimate partners, given their chronic stress exposure. In 65 couples (male Veterans, female partners), elevated PTSD symptomatology (n = 32; 28 met full DSM IV criteria, 4 fell slightly short) was documented by structured interview and self-reports. Baseline HR, high-frequency HRV (HF-HRV), cardiac pre-ejection period (PEP), and respiration rate and depth were measured via impedance cardiography. Veterans with PTSD symptoms displayed reduced lnHF-HRV, even when adjusting for respiration, but their partners did not. In mediational analyses, elevated resting HR in PTSD was accounted for by lnHF-HRV but not PEP. Results strengthen evidence regarding HF-HRV and elevated HR in PTSD.

Abstract
PURPOSE OF REVIEW Eating disorders (EDs) and overweight/obesity (OW/OB) have a significant impact on veterans. This review highlights current research on EDs and OW/OB in this population. RECENT FINDINGS Prevalence estimates for both EDs and OW/OB among veterans remain consistent with and possibly higher than those in the general population. Both diagnoses share multiple risk factors, including trauma history, and mental health comorbidities. Although weight loss treatments have been fairly well studied among veteran samples, there are no published investigations on psychotherapies for EDs in this population. The Veterans Healthcare Administration is working to train providers in ED treatments. VHA treatments for OW/OB show some benefits and areas for improvement. Areas for future research include structured assessments for EDs and disordered eating behaviors in veterans to clarify prevalence estimates. There is a need for interventions that consider common mechanisms for ED and OW/OB, and there is a need for more research on the associations between different types of trauma and ED/OW/OB in veterans.

Abstract
BACKGROUND While post-traumatic stress disorder (PTSD) is defined by behavioral/cognitive symptoms most directly relevant to brain function, it can be considered a systemic disorder characterized by a distinct inability to reinstate homeostasis after trauma. METHODS In this study, we conducted a secondary analysis of gene expression profiles in key PTSD-relevant tissues, namely blood, amygdala, and hippocampus, from a rat model of PTSD, to identify sex-specific and shared processes associated with individual differences in response to recent trauma exposure. RESULTS Our findings suggest both shared and sex-specific mechanisms underlying individual differences associated with vulnerability and resilience to trauma in hippocampus, amygdala, and blood. By disentangling cell composition from transcriptional changes, we found higher proportions of hippocampal oligodendrocytes in the PTSD-like, extreme behavioral response (EBR) group for both sexes and also identified modules for transcriptional activity associated with group differences (i.e., response to trauma) in the hippocampus that appeared to be sex-specific. By contrast, we found prominent sex differences, but no group differences, in amygdalar cell composition, and both shared and sex-specific modules representing PTSD-relevant transcriptional activity in the amygdala. Across amygdala and hippocampus, both sex-specific and shared processes were relevant to an overarching framework for EBR implicating disrupted TNFα/NFκΒ signaling and excitatory/inhibitory imbalance in dysregulated synaptic/structural plasticity with important implications for fear learning and memory. Our main finding in peripheral blood was consistent with the human literature and identified wound healing processes and hemostasis to be upregulated in the resilient, minimal behavioral response (MBR) group across sexes, but disrupted in a sexually dimorphic manner in the EBR group. CONCLUSION In contrast to the varied characterization of the PTSD-like EBR group, characterization of MBR across blood, amygdala, and hippocampus suggests a common theme of upregulated wound healing and extracellular matrix (ECM) remodeling shared between sexes. In all, we identified differential oligodendrocyte proportions in hippocampus between PTSD-like EBR and resilient MBR, and identified processes and pathways that characterize the EBR and MBR-associated transcriptional changes across hippocampus, amygdala, and blood. The sex-specific mechanisms involved in EBR may contribute to the pronounced disparity in risk for PTSD, with women much more likely to develop PTSD.
