AbstractConstitutional thinness and anorexia nervosa are both characterised by persistent, extremely low weight with body mass indices (BMI) below 18.5 kg/m2. Individuals with anorexia nervosa concurrently show distorted perceptions of their own body and engage in weight-loss behaviours, whereas individuals with constitutional thinness typically wish to gain weight. Both are heritable, share genomics with BMI, but have not been shown to be genetically correlated with each other. We aim to differentiate between constitutional thinness and anorexia nervosa on a genomic level.First, we estimated genetic correlations between constitutional thinness and eleven psychiatric disorders and compared them with anorexia nervosa using publicly available data. Second, we identified individuals with constitutional thinness in the Avon Longitudinal Study of Parents and Children (ALSPAC) by latent class growth analysis of measured BMI from 10 to 24 years (n = 8,505) and assigned polygenic scores for eleven psychiatric disorders and a range of anthropometric traits to evaluate associations.In contrast to anorexia nervosa, attention deficit hyperactivity disorder (rgAN = 0.02 vs. rgCT = −0.24) and alcohol dependence (rgAN = 0.07 vs. rgCT = −0.44) showed a statistically significant negative genetic correlation with constitutional thinness. A higher polygenic score for posttraumatic stress disorder was associated with an increased risk of constitutional thinness in the ALSPAC cohort (OR = 1.27; Q = 0.03) whereas posttraumatic stress disorder shows no genetic correlation with anorexia nervosa (rg = −0.02). Overall, results suggest that constitutional thinness is different from anorexia nervosa on the genomic level.

Analytic Review

Context: Recent evidence suggests that posttraumatic stress disorder (PTSD) may be associated with increased risk for coronary heart disease (CHD). Objective: To determine the association of PTSD to incident CHD using systematic review and meta-analysis. Data Sources: Articles were identified by searching Ovid MEDLINE, PsycINFO, Scopus, Cochrane Library, PILOTS database, and through manual search of reference lists. Study Selection: Prospective cohort studies that assessed PTSD in participants free of CHD and assessed subsequent CHD or cardiac-specific mortality. Data Extraction: We extracted estimates of the association of PTSD to incident CHD, as well as study characteristics. Odds ratios were converted to hazard ratios (HR), and a random-effects model was used to pool results. Data Synthesis: Five studies met our inclusion criteria (N= 401,712); 4 of these included depression as a covariate. The pooled HR for the magnitude of the relationship between PTSD and CHD was 1.53 (95% CI, 1.27-1.84) before adjustment for depression. The pooled HR estimate for the 4 depression-adjusted estimates (N= 362,388) was 1.22 (95% CI, 1.05-1.42). Conclusion: PTSD is independently associated with increased risk for incident CHD, even after adjusting for depression and other covariates. Figure 1. Forest plot of association of PTSD to incident MI or cardiac mortality Note: The area of each square is proportional to the study’s weight in the meta-analysis, and each line represents the confidence interval around the estimate. The diamond represents the aggregate estimate, and its lateral points indicate confidence intervals for this estimate.

Subcortical Volumes

AbstractThe volume of subcortical structures represents a reliable, quantitative, and objective phenotype that captures genetic effects, environmental effects such as trauma, and disease effects such as posttraumatic stress disorder (PTSD). Trauma and PTSD represent potent exposures that may interact with genetic markers to influence brain structure and function. Genetic variants, associated with subcortical volumes in two large normative discovery samples, were used to compute polygenic scores (PGS) for the volume of seven subcortical structures. These were applied to a target sample enriched for childhood trauma and PTSD. Subcortical volume PGS from the discovery sample were strongly associated in our trauma/PTSD enriched sample (n = 7580) with respective subcortical volumes of the hippocampus (p = 1.10 × 10−20), thalamus (p = 7.46 × 10−10), caudate (p = 1.97 × 10−18), putamen (p = 1.7 × 10−12), and nucleus accumbens (p = 1.99 × 10−7). We found a significant association between the hippocampal volume PGS and hippocampal volume in control subjects from our sample, but was absent in individuals with PTSD (GxE; (beta = −0.10, p = 0.027)). This significant GxE (PGS × PTSD) relationship persisted (p < 1 × 10−19) in four out of five threshold peaks (0.024, 0.133, 0.487, 0.730, and 0.889) used to calculate hippocampal volume PGSs. We detected similar GxE (G × ChildTrauma) relationships in the amygdala for exposure to childhood trauma (rs4702973; p = 2.16 × 10−7) or PTSD (rs10861272; p = 1.78 × 10−6) in the CHST11 gene. The hippocampus and amygdala are pivotal brain structures in mediating PTSD symptomatology. Trauma exposure and PTSD modulate the effect of polygenic markers on hippocampal volume (GxE) and the amygdala volume PGS is associated with PTSD risk, which supports the role of amygdala volume as a risk factor for PTSD.

End Stage

For persons with HIV and AIDS, a thorough and comprehensive assessment has far-reaching implications not only for compassionate, competent, and coordinated care but also for adherence to medical treatment and risk reduction, as well as public health. Primary physicians, HIV specialists, as well as psychiatrists and other mental health professionals can play an important role in preventing the spread of HIV infection. Psychiatric disorders are associated with inadequate adherence to risk reduction, medical care, and antiretroviral therapy. While adherence to medical care for most medical illnesses has major meaning to patients, loved ones, and families, adherence to medical care for HIV and AIDS has major implications for reduction of HIV transmission and prevention of emergence of drug-resistant HIV viral strains (Cohen and Chao, 2008). Many persons with HIV and AIDS have psychiatric disorders (Stoff et al., 2004) and can benefit from psychiatric consultation and care. The rates of HIV infection are also higher among persons with serious mental illness (Blank et al., 2002), indicating a bidirectional relationship. Some persons with HIV and AIDS have no psychiatric disorder, while others have a multiplicity of complex psychiatric disorders that are responses to illness or treatments or are associated with HIV/AIDS (such as HIV-associated dementia) or multimorbid medical illnesses and treatments (such as hepatitis C, cirrhosis, end-stage liver disease, HIV nephropathy, end-stage renal disease, anemia, coronary artery disease, and cancer). Persons with HIV and AIDS may also have multimorbid psychiatric disorders that are co-occurring and may be unrelated to HIV (such as posttraumatic stress disorder, or PTSD, schizophrenia, and bipolar disorder). The complexity of AIDS psychiatric consultation is illustrated in an article (Freedman et al., 1994) with the title “Depression, HIV Dementia, Delirium, Posttraumatic Stress Disorder (or All of the Above).” Comprehensive psychiatric evaluations can provide diagnoses, inform treatment, and mitigate anguish, distress, depression, anxiety, and substance use in persons with HIV and AIDS. Furthermore, thorough and comprehensive assessment is crucial because HIV has an affinity for brain and neural tissue and can cause central nervous system (CNS) complications even in healthy seropositive individuals. Because of potential CNS complications as well as the multiplicity of other severe and complex medical illnesses in persons with HIV and AIDS (Huang et al., 2006), every person who is referred for a psychiatric consultation needs a full biopsychosocial evaluation.

Posttraumatic stress disorder (PTSD) is a psychiatric illness that is more prevalent in women, and accumulating evidence suggests a link between PTSD and future development of cardiovascular disease. The underlying mechanisms are unclear, but augmented sympathetic reactivity to daily stressors may be involved. We measured muscle sympathetic nerve activity (MSNA), blood pressure (BP), and heart rate responses in 14 women with PTSD and 14 healthy women (controls) during static handgrip (SHG) exercise to fatigue at 40% of maximal voluntary contraction (MVC). Two minutes of postexercise circulatory arrest (PECA) was followed immediately after SHG to fatigue. MVC and the time to fatigue during SHG did not differ between groups (both P > 0.05). At the first 30 s of SHG, women with PTSD showed augmented sympathetic neural [mean ± SD, ∆MSNA burst frequency (BF): 5 ± 4 vs. 2 ± 3 bursts/30 s, P = 0.02 and ∆MSNA total activity (TA): 82 ± 58 vs. 25 ± 38 arbitrary units/30 s, P = 0.004] and pressor (∆systolic BP: 10 ± 5 vs. 4 ± 3 mmHg, P = 0.003) responses compared with controls. However, MSNA and BP responses at fatigue and during PECA were not different between groups. More interestingly, the augmented initial neural and pressor responses to SHG were associated with greater awake systolic BP variability during ambulation in women with PTSD (MSNA BF: r = 0.55, MSNA TA: r = 0.62, and SBP: r = 0.69, all P < 0.05). These results suggest that early onset exercise pressor response in women with PTSD may be attributed to enhanced mechano- rather than metaboreflexes, which might contribute to the mechanisms underlying the link between PTSD and cardiovascular risk. NEW & NOTEWORTHY The novel findings of the current study are that women with posttraumatic stress disorder (PTSD) exhibited augmented sympathetic neural and pressor responses at the first 30 s of submaximal isometric muscle contraction. More interestingly, exaggerated neurocirculatory responses at the onset of muscle contraction were associated with greater ambulatory awake systolic blood pressure fluctuations in women with PTSD. Our findings expand the knowledge on the physiological mechanisms that perhaps contribute to increased risk of cardiovascular disease in such a population.

Background To identify reasons for increased atherosclerotic risk among women living with HIV ( WLWH ), we evaluated the associations between psychosocial risk factors (depressive symptoms, perceived stress, and posttraumatic stress disorder symptoms) and subclinical atherosclerosis among WLWH and HIV ‐negative women. Methods and Results Carotid artery focal plaque (localized intima‐media thickness >1.5 mm) was measured using B‐mode ultrasound imaging in 2004–2005 and 2010–2012 in the Women's Interagency HIV Study. We created psychosocial risk groups using latent class analysis and defined prevalent plaque at the final measurement. We also examined repeated semiannual depression measures with respect to focal plaque formation throughout follow‐up. The associations between latent class and prevalent plaque, and between depressive symptom persistence and plaque formation, were assessed separately by HIV status using multivariable logistic regression. Among 700 women (median age 47 years), 2 latent classes were identified: high (n=163) and low (n=537) psychosocial risk, with corresponding prevalence of depression (65%/13%), high stress (96%/12%), and probable posttraumatic stress disorder (46%/2%). Among WLWH , plaque prevalence was 23% and 11% in high versus low psychosocial risk classes (adjusted odds ratio [aOR], 2.12; 95% CI, 1.11–4.05) compared with 9% and 9% among HIV ‐negative women (aOR, 1.07; 95% CI, 0.24–4.84), respectively. New plaque formation occurred among 17% and 9% of WLWH who reported high depressive symptoms at ≥45% versus <45% of visits (aOR, 1.96; 95% CI, 1.06–3.64), compared with 9% and 7% among HIV ‐negative women (aOR, 0.82; 95% CI, 0.16–4.16), respectively. Conclusions Psychosocial factors were independent atherosclerotic risk factors among WLWH . Research is needed to determine whether interventions for depression and psychosocial stress can mitigate the increased risk of atherosclerosis for WLWH .

Abstract Background Research exploring the longitudinal course of posttraumatic stress disorder (PTSD) symptoms has documented four modal trajectories (low, remitting, high, and delayed), with proportions varying across studies. Heterogeneity could be due to differences in trauma types and patient demographic characteristics. Methods This analysis pooled data from six longitudinal studies of adult survivors of civilian-related injuries admitted to general hospital emergency departments (EDs) in six countries (pooled N = 3083). Each study included at least three assessments of the clinician-administered PTSD scale in the first post-trauma year. Latent class growth analysis determined the proportion of participants exhibiting various PTSD symptom trajectories within and across the datasets. Multinomial logistic regression analyses examined demographic characteristics, type of event leading to the injury, and trauma history as predictors of trajectories differentiated by their initial severity and course. Results Five trajectories were found across the datasets: Low (64.5%), Remitting (16.9%), Moderate (6.7%), High (6.5%), and Delayed (5.5%). Female gender, non-white race, prior interpersonal trauma, and assaultive injuries were associated with increased risk for initial PTSD reactions. Female gender and assaultive injuries were associated with risk for membership in the Delayed (v. Low) trajectory, and lower education, prior interpersonal trauma, and assaultive injuries with risk for membership in the High (v. Remitting) trajectory. Conclusions The results suggest that over 30% of civilian-related injury survivors admitted to EDs experience moderate-to-high levels of PTSD symptoms within the first post-trauma year, with those reporting assaultive violence at increased risk of both immediate and longer-term symptoms.

This study examined the association between symptoms of Posttraumatic Stress Disorder (PTSD) in male Vietnam veterans and their use of aggressive behavior in relationships with intimate female partners. Fifty couples participated in the study. Veterans reported on their PTSD symptoms, and veterans and partners completed measures assessing the veterans’ use of physical, verbal,’ and psychological aggression during the preceding year as well as measures of their own perceptions of problems in the relationship. Results indicated that PTSD symptomatology places veterans at increased risk for perpetrating relationship aggression against their partners. The association between veterans’ PTSD symptoms and their use of aggression in relationships was mediated by relationship problems. Clinical implications of these findings and suggestions for future research are discussed.

Background: Military veterans have higher rates of suicidality and completed suicides compared to the general population. Previous research has demonstrated suicidal behaviour is higher in US combat veterans who are younger, suffer from posttraumatic stress disorder, depression and anxiety and score lower on measures of health. However, research on predictors of suicide for Australian veterans is limited. The aim of this study was to identify significant demographic and psychological differences between veterans with posttraumatic stress disorder who had attempted suicide and those with posttraumatic stress disorder who had not, as well as determine predictors of suicide attempts within an Australian cohort. Methods: A retrospective analysis was conducted on 229 ex-service personnel diagnosed with posttraumatic stress disorder who had attended a Military Service Trauma Recovery Day Program as outpatients at Toowong Private Hospital from 2007 to 2014. Patients completed a battery of mental health self-report questionnaires assessing symptoms of posttraumatic stress disorder, alcohol use, anger, depression, anxiety and quality of life. Demographic information and self-reported history of suicide attempts were also recorded. Results: Results indicated the average age was significantly lower, and the rates of posttraumatic stress disorder, anger, anxiety and depression symptoms were significantly higher in those veterans with history of a suicide attempt. Multivariate logistic regression analyses indicated posttraumatic stress disorder symptom severity, unemployment or total and permanent incapacity pension status significantly predicted suicide attempt history. Conclusion: Among a cohort of Australian veterans with posttraumatic stress disorder, psychopathology severity, unemployment and total and permanent incapacity status are significantly associated with suicidality. This study highlights the importance of early identification of posttraumatic stress disorder and psychopathology, therapeutic and social engagement, and prioritisation of tangible employment options or meaningful and goal-directed activities for veterans deemed unable to work.
