Abstract
Hypertension contributes to significant global health and economic burdens. The American College of Cardiology/American Heart Association's latest guideline lowers the blood pressure threshold for hypertension, and as a result, the number of adults with hypertension has increased. Hypertension is a major risk factor for cardiovascular morbidity, especially among older adults. Many individuals who are diagnosed with hypertension at the new, lower threshold may benefit from lifestyle counseling, but changes to existing Medicare policies are required to increase utilization of evidence-based lifestyle counseling approaches to hypertension management. We recommend appropriate funding for the reimbursement of evidence-based lifestyle counseling for hypertension management, the expansion of medical nutrition therapy counseling coverage as an option for Medicare beneficiaries with hypertension, the inclusion of home-based blood pressure monitoring devices in the list of Durable Medical Equipment Coverage, and modifications to the Medicare Benefit Policy Manual to prioritize evidence-based programs such as Dietary Approaches to Stop Hypertension, American Heart Association, and plant-predominant dietary programs.

Abstract
Posttraumatic stress disorder (PTSD) has increasingly been linked to heightened systemic inflammation. It matters whether this association is causal (and either bidirectional or unidirectional) or correlational. Investigators have hypothesized that chronic systemic low-grade inflammation may contribute to greater risk of developing PTSD after experiencing trauma and/or serve as a mechanism linking PTSD to adverse physical health outcomes. However, if the PTSD-inflammation relation is correlational, it may not warrant further research aimed at understanding inflammation as a PTSD risk factor or as a pathway linking PTSD with poor health. In this review, we first assess the longitudinal evidence related to PTSD and inflammation to understand more clearly the directionality and causal nature of this relation. Overall, few longitudinal studies rigorously assess the direction of the PTSD-inflammation relation. Some of the evidence indicates that elevated inflammation assessed pretrauma or in the acute aftermath of trauma increases risk for developing PTSD. Fewer studies evaluate the influence of PTSD on subsequent inflammation levels, and findings are mixed. Sample characteristics and study designs, and also the type of inflammation-related measure, vary widely across studies. Based on current evidence, we then recommend several statistical and study design approaches that may help untangle issues of bidirectionality and aid in determining the direction of causality between PTSD and inflammation. Last, we conclude with future research directions and consider potential implications for interventions or treatment approaches based on this growing body of literature.

Abstract
BACKGROUND Although early life adversity (ELA) increases risk for psychopathology, mechanisms linking ELA with the onset of psychopathology remain poorly understood. Conceptual models have argued that ELA accelerates development. It is unknown whether all forms of ELA are associated with accelerated development or whether early maturation is a potential mechanism linking ELA with psychopathology. We examine whether two distinct dimensions of ELA - threat and deprivation - have differential associations with pubertal timing in girls, and evaluate whether accelerated pubertal timing is a mechanism linking ELA with the onset of adolescent psychopathology. METHODS Data were drawn from a large, nationally representative sample of 4937 adolescent girls. Multiple forms of ELA characterized by threat and deprivation were assessed along with age at menarche (AAM) and the onset of DSM-IV fear, distress, externalizing, and eating disorders. RESULTS Greater exposure to threat was associated with earlier AAM (B = -0.1, p = 0.001). Each 1-year increase in AAM was associated with reduced odds of fear, distress, and externalizing disorders post-menarche (ORs = 0.74-0.85). Earlier AAM significantly mediated the association between exposure to threat and post-menarche onset of distress (proportion mediated = 6.2%), fear (proportion mediated = 16.3%), and externalizing disorders (proportion mediated = 2.9%). CONCLUSIONS Accelerated pubertal development in girls may be one transdiagnostic pathway through which threat-related experiences confer risk for the adolescent onset of mental disorders. Early pubertal maturation is a marker that could be used in both medical and mental health settings to identify trauma-exposed youth that are at risk for developing a mental disorder during adolescence in order to better target early interventions.

Abstract
OBJECTIVE There is some evidence that posttraumatic stress disorder (PTSD) is associated with increased risk of infections, and it is unknown whether adjustment disorder is as well. We assessed the association between adjustment disorder and subsequent infections, and assessed additive interaction with sex. METHODS The study population included a nationwide cohort of all Danish-born residents of Denmark diagnosed with adjustment disorder between 1995 and 2011, and an age- and sex-matched general population comparison cohort. We compared rates of infections requiring inpatient or outpatient hospitalization in the two cohorts. We fit Cox proportional hazards models to compute adjusted hazard ratios (aHR) for the associations between adjustment disorder and 32 types of infections, and calculated interaction contrasts to assess interaction between adjustment disorder and sex. RESULTS Adjustment disorder was associated with increased rates of infections overall (n = 19,838 infections, aHR = 1.8, 95% confidence interval = 1.8. 1.9), and increased rates of each individual infection type (aHRs for 30 infections ranged from 1.5 to 2.3), adjusting for baseline psychiatric and somatic comorbidities and marital status. For many infection types (e.g., skin infections, pneumonia), interaction contrasts indicated rate differences were greater among men than women, while for two (urinary tract infections and sexually transmitted infections), rate differences were greater for women. CONCLUSIONS These findings are consistent with studies examining the relationship between psychological stress and infections, and between PTSD and infections. They may be explained by a combination of the triggering of unhealthy behaviors as well as immune responses to stress.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) is associated with higher risk of incident hypertension, but it is unclear whether specific aspects of PTSD are particularly cardiotoxic. PTSD is a heterogeneous disorder, comprising dimensions of fear and dysphoria. Because elevated fear after trauma may promote autonomic nervous system dysregulation, we hypothesized fear would predict hypertension onset, and associations with hypertension would be stronger with fear than dysphoria. METHODS We examined fear and dysphoria symptom dimensions in relation to incident hypertension over 24 years in 2709 trauma-exposed women in the Nurses' Health Study II. Posttraumatic fear and dysphoria symptom scores were derived from a PTSD diagnostic interview. We used proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for each symptom dimension (quintiles) with new-onset hypertension events (N = 925), using separate models. We also considered lower-order symptom dimensions of fear and dysphoria. RESULTS Higher levels of fear (P-trend = 0.02), but not dysphoria (P-trend = 0.22), symptoms were significantly associated with increased hypertension risk after adjusting for socio-demographics and family history of hypertension. Women in the highest v. lowest fear quintile had a 26% higher rate of developing hypertension [HR = 1.26 (95% CI 1.02-1.57)]; the increased incidence associated with greater fear was similar when further adjusted for biomedical and health behavior covariates (P-trend = 0.04) and dysphoria symptoms (P-trend = 0.04). Lower-order symptom dimension analyses provided preliminary evidence that the re-experiencing and avoidance components of fear were particularly associated with hypertension. CONCLUSIONS Fear symptoms associated with PTSD may be a critical driver of elevated cardiovascular risk in trauma-exposed individuals.

Abstract
Social support during childhood lays the foundation for social relationships throughout the life course and has been shown to predict a wide range of mental and physical health outcomes. Social support measured in late life is prospectively associated with better cognitive aging, but few studies have evaluated social support received earlier in the life course. We quantified the effects of childhood social support, reported retrospectively, on later-life cognitive trajectories and investigated biopsychosocial mechanisms underlying these associations. Latent growth curve models estimated 10-year cognitive trajectories in 8,538 participants (baseline ages 45-93; Mage = 63) in the REasons for Geographic And Racial Differences in Stroke (REGARDS) project. Independent of sociodemographics, childhood socioeconomic status, and household size, greater retrospective childhood social support was associated with better initial episodic memory, but not verbal fluency or cognitive change, in later adulthood. Associations with initial memory level were mediated by sociodemographic and psychosocial variables; specifically, those who reported greater childhood social support reported higher educational attainment and had better physical and emotional health in adulthood, which were each associated with better memory. These results provide support for broad and enduring effects of childhood social support on mental, physical, and cognitive health decades later.

Abstract
BACKGROUND Abnormal thyroid function is prevalent among women and has been linked to increased risk of chronic disease. Posttraumatic stress disorder (PTSD) has been linked to thyroid dysfunction in some studies; however, the results have been inconsistent. Thus, we evaluated trauma exposure and PTSD symptoms in relation to incident thyroid dysfunction in a large longitudinal cohort of civilian women. METHODS We used data from 45 992 women from the ongoing Nurses' Health Study II, a longitudinal US cohort study that began in 1989. In 2008, history of trauma and PTSD were assessed with the Short Screening Scale for Diagnostic and Statistical Manual of Mental Disorders, fourth edition, PTSD, and incident thyroid dysfunction was determined by participants' self-report in biennial questionnaires of physician-diagnosed hypothyroidism and Graves' hyperthyroidism. The study period was from 1989 to 2013. Proportional hazard models were used to estimate multivariable-adjusted hazard ratios and 95% confidence intervals (CIs) for incident hypothyroidism and Graves' hyperthyroidism. RESULTS In multivariable-adjusted models, we found significant associations for PTSD only with hypothyroidism [p-trend <0.001; trauma with no PTSD symptoms, 1.08 (95% CI 1.02-1.15); 1-3 PTSD symptoms, 1.12 (95% CI 1.04-1.21); 4-5 PTSD symptoms, 1.23 (95% CI 1.13-1.34); and 6-7 PTSD symptoms, 1.26 (95% CI 1.14-1.40)]. PTSD was not associated with risk of Graves' hyperthyroidism (p-trend = 0.34). Associations were similar in sensitivity analyses restricted to outcomes with onset after 2008, when PTSD was assessed. CONCLUSIONS PTSD was associated with higher risk of hypothyroidism in a dose-dependent fashion. Highlighted awareness for thyroid dysfunction may be especially important in women with PTSD.

Abstract
The risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5-20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men. Along with other novel genes and non-coding RNAs, a Parkinson's disease gene involved in dopamine regulation, PARK2, is associated with PTSD. Finally, we demonstrate that polygenic risk for PTSD is significantly predictive of re-experiencing symptoms in the Million Veteran Program dataset, although specific loci did not replicate. These results demonstrate the role of genetic variation in the biology of risk for PTSD and highlight the necessity of conducting sex-stratified analyses and expanding GWAS beyond European ancestry populations.

Abstract
BACKGROUND Considerable evidence suggests that posttraumatic stress disorder (PTSD) is a heterogeneous construct despite often being treated as a homogeneous diagnostic entity. PTSD in response to cardiac arrest is common and may differ from PTSD following other medical traumas. Most patients are amnesic from the cardiac event, and it is unclear if and how certain PTSD symptoms may manifest. METHODS We examined the latent structure of PTSD symptoms in 104 consecutive cardiac arrest survivors who were admitted to Columbia University Medical Center. PTSD symptoms were assessed via the PTSD Checklist-Specific at hospital discharge. We performed a confirmatory factor analysis (CFA) to compare 4-factor dysphoria, 4-factor numbing, and 5-factor dysphoric arousal models of PTSD with our data. RESULTS The CFA showed that each of the models had good fit. We chose the 4-factor numbing model (χ2 (113) = 151.59, p < .01, CFI = 0.94, RMSEA = 0.057, 90% CI: [0.032, 0.081]) as most representative of the data, after considering a between-factor correlation of 0.99 in the 5-factor dysphoric arousal model, and greater fit statistics than the 4-factor dysphoria model. LIMITATIONS Certain factors were defined by only two items. Additionally, PTSD was assessed at discharge (median = 21 days); those assessed before 30 days could be displaying symptoms of acute stress disorder. CONCLUSIONS Our findings suggest that PTSD symptoms after cardiac arrest are best represented by a 4-factor numbing model of PTSD. PTSD assessment and intervention efforts for cardiac arrest survivors should consider the underlying dimensions of PTSD.

Abstract
Post-traumatic stress disorder (PTSD) induced by life-threatening medical events has been associated with adverse physical and mental health outcomes, but it is unclear whether early interventions to prevent the onset of PTSD after these events are efficacious. We conducted a systematic review to address this need. We searched six biomedical electronic databases from database inception to October 2018. Eligible studies used randomized designs, evaluated interventions initiated within 3 months of potentially traumatic medical events, included adult participants, and did not have high risk of bias. The 21 included studies (N = 4,486) assessed a heterogeneous set of interventions after critical illness (9), cancer diagnosis (8), heart disease (2), and cardiopulmonary surgery (2). Fourteen psychological, 2 pharmacological, and 5 other-type interventions were assessed. Four of the psychological interventions emphasizing cognitive behavioral therapy or meaning-making, 1 other-type palliative care intervention, and 1 pharmacological-only intervention (hydrocortisone administration) were efficacious at reducing PTSD symptoms relative to control. One early, in-hospital counseling intervention was less efficacious at lowering PTSD symptoms than an active control. Clinical and methodological heterogeneity prevented quantitative pooling of data. While several promising interventions were identified, strong evidence of efficacy for any specific early PTSD intervention after medical events is currently lacking.

Abstract
Introduction The relation between TV viewing and posttraumatic stress disorder (PTSD) is controversial; prior work focused exclusively on whether TV viewing of disaster events constitutes a traumatic stressor that causes PTSD. This study evaluates a possible bidirectional relation between PTSD and TV viewing in community-dwelling women. Methods Data are from the PTSD subsample of the Nurses’ Health II study, an ongoing prospective study of women aged 24–42 years at enrollment and who have been followed biennially (N = 50,020). Trauma exposure and PTSD symptoms (including date of onset) were assessed via the Brief Trauma Questionnaire and the Short Screening Scale for DSM-IV PTSD. Average TV viewing was reported at 5 times over 18 years of follow-up. Linear mixed models assessed differences in TV viewing patterns by trauma/PTSD status. Among women with trauma/PTSD onset during follow-up (N = 14,374), linear spline mixed models assessed differences in TV viewing patterns before and after PTSD onset. Results Women with high PTSD symptoms reported more TV viewing (hours/wk) compared to trauma-unexposed women at all follow-up assessments (β = 0.14, SE = 0.01, p < .001). Among the women who experienced trauma during follow-up, significant increases in TV viewing (hours/day) prior to onset of high PTSD symptom levels were evident (β = 0.15, SE = 0.02, p < .001). Conclusions TV viewing following trauma exposure may be a marker of vulnerability for developing PTSD and also a consequence of having PTSD. High TV viewing levels may be linked with ineffective coping strategies or social isolation, which increase risk of developing PTSD.

Abstract
While nausea often develops following exposure to trauma, little is known regarding the relationship between peri-traumatic nausea and prospective risk for developing posttraumatic stress disorder (PTSD). We examined the association between peri-traumatic nausea and PTSD symptom development in three independent cohorts. Participants were recruited from (1) the Emergency Departments (ED) at Grady Memorial Hospital (GMH) in Atlanta, GA, (2) from multiple other ED sites in the TRYUMPH Research Network, and (3) from the ED during evaluation for suspected acute coronary syndrome in the REACH cohort. Administration of IV ondansetron, the most predominant antiemetic used at GMH, was used as a surrogate marker for nausea in the initial GMH cohort; nausea was then directly assessed in the internal validation at GMH, and within the replication TRYUMPH Research Network and REACH cohorts. In the GMH cohort (N = 363), ondansetron administration was associated with increased 1- and 3-month posttrauma PTSD symptoms in adjusted models (all p's < 0.05). In the GMH internal validation, nausea significantly predicted 1 month (p = 0.009; n = 68) and 3 month (p = 0.029; n = 54) PTSD symptoms. In the TRYUMPH cohort (N = 1846), patient reported nausea in the ED was significantly associated with increased PTSD symptoms (p = 0.009) in adjusted models. In the REACH cohort (N = 758), peri-traumatic nausea was associated with PTSD symptom severity at the 1-month follow-up in adjusted models (p's ≤ 0.008). The current prospective data from three independent cohorts suggest that peri-traumatic nausea is a prospective predictor of PTSD symptom development. Further studies are needed to determine the mechanistic role of nausea as an intermediate phenotype of PTSD risk.

Abstract
BACKGROUND Recent conceptual models argue that early life adversity (ELA) accelerates development, which may contribute to poor mental and physical health outcomes. Evidence for accelerated development in youths comes from studies of telomere shortening or advanced pubertal development following circumscribed ELA experiences and neuroimaging studies of circuits involved in emotional processing. It is unclear whether all ELA is associated with accelerated development across global metrics of biological aging or whether this pattern emerges following specific adversity types. METHODS In 247 children and adolescents 8 to 16 years of age with wide variability in ELA exposure, we evaluated the hypothesis that early environments characterized by threat, but not deprivation, would be associated with accelerated development across two global biological aging metrics: DNA methylation (DNAm) age and pubertal stage relative to chronological age. We also examined whether accelerated development explained associations of ELA with depressive symptoms and externalizing problems. RESULTS Exposure to threat-related ELA (e.g., violence) was associated with accelerated DNAm age and advanced pubertal stage, but exposure to deprivation (e.g., neglect, food insecurity) was not. In models including both ELA types, threat-related ELA was uniquely associated with accelerated DNAm age (β = .18) and advanced pubertal stage (β = .28), whereas deprivation was uniquely associated with delayed pubertal stage (β = -.21). Older DNAm age was related to greater depressive symptoms, and a significant indirect effect of threat exposure on depressive symptoms was observed through DNAm age. CONCLUSIONS Early threat-related experiences are particularly associated with accelerated biological aging in youths, which may be a mechanism linking ELA with depressive symptoms.

Abstract
OBJECTIVE Prior posttraumatic stress disorder (PTSD) and elevated threat perceptions predict posttraumatic psychopathology after evaluation for acute coronary syndrome (ACS), but most research has measured threat retrospectively. We investigated how threat perceptions during ACS evaluation in the emergency department (ED) and upon recall were associated with posttraumatic psychopathology burden due to prior trauma and the suspected ACS. METHODS Perceived threat was assessed in the ED, and ED threat recall was assessed upon inpatient transfer/discharge, along with acute stress disorder (ASD) symptoms due to suspected ACS and PTSD symptoms due to prior trauma. The sample comprised 894 participants (mean age = 60.7 ± 13.1 years; 46.8% female; 56.3% Hispanic; 20.5% Black). One-way ANOVAs examined how those with consistent posttraumatic psychopathology (prior PTSD/ASD; 14.8%), prior posttraumatic psychopathology (prior PTSD/no ASD; 6.8%), new-onset posttraumatic psychopathology (no PTSD/ASD; 15.7%), or no posttraumatic psychopathology (no PTSD/no ASD; 62.8%) differed in threat perception, threat recall, and their discrepancy. RESULTS Threat perception scores ranged from 6 to 24. Participants with consistent posttraumatic psychopathology had higher threat perceptions (M = 14.01) than those with prior posttraumatic psychopathology (M = 12.02) and new-onset posttraumatic psychopathology (M = 12.21) (ps ≤ 0.001); the latter two did not differ significantly but had higher threat perceptions than those with no posttraumatic psychopathology (M = 9.84) (p < .001). Similar results were observed for threat recall (p < .001). The new-onset posttraumatic psychopathology group also had a greater increase in perceived threat versus the no posttraumatic psychopathology group (p = .06). Results were similar adjusting for potential confounders. CONCLUSIONS Assessing threat perceptions during ACS evaluation and hospitalization may help identify those at risk for emotional difficulties post-ACS.

Abstract
INTRODUCTION The experience of negative emotions (eg, anger, anxiety and sadness) is associated with an increased short-term risk of incident cardiovascular disease (CVD) events, independent of traditional CVD risk factors. Impairment in endothelial function is one possible biological mechanism which may explain the association between negative emotions and incident CVD events. This laboratory-based, single-blind, randomised controlled experimental study aims to investigate the impact of induced negative emotions including anger, anxiety and sadness on endothelial function. METHODS AND ANALYSIS In a between-subjects design, 280 healthy participants are randomised to one of four experimental negative emotion inductions: anger, anxiety, sadness or a neutral condition. Endothelium-dependent vasodilation, circulating levels of endothelial cell-derived microparticles and bone marrow-derived endothelial progenitor cells, and indices of nitric oxide inhibition are assessed before and 3, 40, 70 and 100 min after negative emotion induction. Finally, in a subsample of 84 participants, the potential moderating effects of cardiorespiratory fitness and habitual physical activity on the adverse effects of an acute negative emotion on endothelial function are investigated. ETHICS AND DISSEMINATION This study is conducted in compliance with the Helsinki Declaration and the Columbia University Medical Center Institutional Review Board. The results of the study will be disseminated at several research conferences and as published articles in peer reviewed journals. The study will be implemented and reported in line with the SPIRIT statement. TRIAL REGISTRATION NUMBER NCT01909895; Pre-results.

Abstract
BACKGROUND Women with a history of hypertensive disorders of pregnancy and preterm delivery have an increased risk of cardiovascular disease (CVD). Chronic inflammation, endothelial dysfunction, and dyslipidemia may link pregnancy outcomes with CVD. OBJECTIVE We evaluated whether women with a history of HDP or normotensive preterm delivery had adverse CVD biomarker profiles after pregnancy. STUDY DESIGN We identified parous women from the Nurses' Health Study II with C-reactive protein (CRP; n = 2614), interleukin-6 (IL-6; n = 2490), glycated hemoglobin (n = 885), intracellular adhesion molecule-1 (n = 1231), high density lipoprotein cholesterol (n = 931), low density lipoprotein cholesterol (n = 931), triglycerides (n = 1428), or total cholesterol (n = 2940) assessed in stored blood samples. Multivariable-adjusted robust linear regression models evaluated percent differences and 95% confidence intervals (CIs) in each biomarker associated with a history of HDP or preterm delivery. RESULTS Ten percent of women had a history of HDP, while 11% with normotensive pregnancies had at least one preterm delivery. Median time from first pregnancy to blood draw was 17 years (interquartile range: 12, 22). Plasma levels of CRP and IL-6 were 34.4% (95% CI: 17.2, 54.1), and 11.6% higher (95% CI: 2.1, 21.9) respectively, among women with a history of HDP compared to those with only normotensive pregnancies. Altered CVD biomarker levels were otherwise not present in women with a history of HDP or preterm delivery. CONCLUSION CRP and IL-6, but not other CVD biomarkers, were elevated in women with a history of HDP in the years following pregnancy, suggesting inflammation may be a pathway linking HDP with future CVD risk.

Abstract
The Psychiatric Genomics Consortium-Posttraumatic Stress Disorder group (PGC-PTSD) combined genome-wide case-control molecular genetic data across 11 multiethnic studies to quantify PTSD heritability, to examine potential shared genetic risk with schizophrenia, bipolar disorder, and major depressive disorder and to identify risk loci for PTSD. Examining 20 730 individuals, we report a molecular genetics-based heritability estimate (h2SNP) for European-American females of 29% that is similar to h2SNP for schizophrenia and is substantially higher than h2SNP in European-American males (estimate not distinguishable from zero). We found strong evidence of overlapping genetic risk between PTSD and schizophrenia along with more modest evidence of overlap with bipolar and major depressive disorder. No single-nucleotide polymorphisms (SNPs) exceeded genome-wide significance in the transethnic (overall) meta-analysis and we do not replicate previously reported associations. Still, SNP-level summary statistics made available here afford the best-available molecular genetic index of PTSD-for both European- and African-American individuals-and can be used in polygenic risk prediction and genetic correlation studies of diverse phenotypes. Publication of summary statistics for ∼10 000 African Americans contributes to the broader goal of increased ancestral diversity in genomic data resources. In sum, the results demonstrate genetic influences on the development of PTSD, identify shared genetic risk between PTSD and other psychiatric disorders and highlight the importance of multiethnic/racial samples. As has been the case with schizophrenia and other complex genetic disorders, larger sample sizes are needed to identify specific risk loci.

Abstract
BACKGROUND Research has linked posttraumatic stress disorder (PTSD) with higher circulating levels of inflammatory and endothelial function (EF) biomarkers, and effects may be bidirectional. We conducted the first investigation of new-onset PTSD and changes in inflammatory and EF biomarkers. METHODS Data were from women in the Nurses' Health Study II. Biomarkers obtained at two blood draws, 10-16 years apart, included C-reactive protein (CRP), tumor necrosis factor-alpha receptor-II (TNFRII), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1). PTSD was assessed via interview. Analyses compared biomarker levels in women with PTSD that onset between draws (n = 175) to women with no history of trauma (n = 175) and to women with history of trauma at draw 1 and no PTSD at either draw (n = 175). We examined if PTSD onset was associated with biomarker change over time and if pre-PTSD-onset biomarker levels indicated risk of subsequent PTSD using linear mixed models and linear regression, respectively. Biomarkers were log-transformed. RESULTS Compared to women without trauma, women in the PTSD onset group had larger increases in VCAM-1 over time (b = 0.003, p = .068). They also had higher TNFRII (b = 0.05, p = .049) and ICAM-1 (b = 0.04, p = .060) levels at draw 1 (prior to trauma and PTSD onset). However, pre-PTSD-onset biomarker levels did not predict onset of more severe PTSD. CONCLUSIONS PTSD onset (vs. no trauma) was associated with increases in one inflammation-related biomarker. Effects may be small and cumulative; longer follow-up periods with larger samples are needed. We did not observe strong support that pre-PTSD-onset biomarkers predicted risk of subsequent PTSD.

Abstract
Medication nonadherence contributes to morbidity/mortality, but adherence interventions yield small and inconsistent effects. Understanding the mechanisms underlying initiation and maintenance of adherence could improve interventions. The National Institutes of Health (NIH) support adherence research, but it is unclear whether existing NIH-funded research incorporates mechanisms. We conducted a systematic review to determine the proportion of NIH-funded adherence trials that have tested hypothesized mechanisms of intervention effects. We included randomized and quasi-randomized NIH-funded trials with medication adherence in adults as the primary outcome. Studies were identified by searching electronic databases from inception to 6/2016, references, and clinicaltrials.gov. Two of 18 (11%) NIH-funded trials tested a hypothesized mechanism of an intervention's effect on medication adherence. Another 44 studies with medication adherence as a secondary outcome were described in protocol form, and are either ongoing or never published results, but none mentioned mechanism tests. Overall, 3% of NIH-funded trials with adherence as an outcome conducted, or plan to conduct, tests of behavior change mechanisms. These results mirror previous findings that very few studies of behavior change interventions actually test the mechanism by which the intervention is hypothesized to improve health behaviors. We must understand mechanisms if we are to improve the effectiveness of interventions.

Abstract
BACKGROUND While both full and subthreshold posttraumatic stress disorder (PTSD) may be linked to physical conditions, contemporary population-based data on these associations in military veterans are scarce. Further, little is known about how component aspects of PTSD, which is a heterogeneous disorder, may relate to physical conditions in this population. METHODS Data were analyzed from a population-based sample of 3157 U.S. military veterans who participated in the 2011 National Health and Resilience in Veterans Study. Multiple logistic regression analyses evaluated associations between full and subthreshold PTSD, and physical conditions. RESULTS A total 6.1% of the sample met screening criteria for full PTSD and 9.0% for subthreshold PTSD. Both full and subthreshold PTSD were associated with increased odds of sleep disorder (adjusted odds ratio [AOR] = 3.52 and 2.10, respectively) and respiratory conditions (AOR = 2.60 and 1.87, respectively). Full PTSD was additionally associated with increased odds of osteoporosis or osteopenia (AOR = 2.72) and migraine (AOR = 1.91), while subthreshold PTSD only was associated with increased odds of diabetes (AOR = 1.42). Analyses of PTSD symptom clusters revealed that all of these associations were primarily driven by dysphoric arousal symptoms, which are characterized by sleep difficulties, anger/irritability, and concentration problems. LIMITATIONS The study used self-report measures for health conditions and DSM-IV diagnostic criteria for PTSD. CONCLUSION Results of this study provide a characterization of physical conditions associated with full and subthreshold PTSD in U.S. military veterans. They highlight the potential importance of PTSD dysphoric arousal in risk models of certain physical conditions in this population.
