Post-traumatic amnesia and the nature of post-traumatic stress disorder after mild traumatic brain injury
The prevalence and nature of post-traumatic stress disorder (PTSD) following mild traumatic brain injury (MTBI) is
controversial because of the apparent paradox of suffering PTSD with impaired memory for the traumatic event. In this
study, 1167 survivors of traumatic injury were assessed for PTSD symptoms and post-traumatic
amnesia during hospitalization, and were subsequently assessed for PTSD 3 months later. At the follow-up
assessment, 90 patients met criteria for PTSD; MTBI patients were more
likely to develop PTSD than no-TBI patients, after controlling for injury severity. Longer post-traumatic amnesia was associated with less severe intrusive memories at
the acute assessment. These findings indicate that PTSD may be more likely following MTBI, however, longer
post-traumatic amnesia appears to be protective against selected re-experiencing symptoms
Clinical practice guideline recommendations to improve the mental health of adult trauma patients:protocol for a systematic review
Introduction Mental disorders are common in adult patients with traumatic injuries. To limit the burden of poor psychological well-being in this population, recognised authorities have issued recommendations through clinical practice guidelines (CPGs). However, the uptake of evidence-based recommendations to improve the mental health of trauma patients has been low until recently. This may be explained by the complexity of optimising mental health practices and interpretating CGPs scope and quality. Our aim is to systematically review CPG mental health recommendations in the context of trauma care and appraise their quality. Methods and analysis We will identify CPG through a search strategy applied to Medline, Embase, CINAHL, PsycINFO and Web of Science databases, as well as guidelines repositories and websites of trauma associations. We will target CPGs on adult and acute trauma populations including at least one recommendation on any prevention, screening, assessment, intervention, patient and family engagement, referral or follow-up procedure related to mental health endorsed by recognised organisations in high-income countries. No language limitations will be applied, and we will limit the search to the last 15 years. Pairs of reviewers will independently screen titles, abstracts, full texts, and carry out data extraction and quality assessment of CPGs using the Appraisal of Guidelines Research and Evaluation (AGREE) II. We will synthesise the evidence on recommendations for CPGs rated as moderate or high quality using a matrix based on the Grading of Recommendations Assessment, Development and Evaluation quality of evidence, strength of recommendation, health and social determinants and whether recommendations were made using a population-based approach. Ethics and dissemination Ethics approval is not required, as we will conduct secondary analysis of published data. The results will be disseminated in a peer-reviewed journal, at international and national scientific meetings. Accessible summary will be distributed to interested parties through professional, healthcare quality and persons with lived experience associations.</p

Publisher Copyright: © 2021 Society of Biological PsychiatryBackground: Posttraumatic stress disorder (PTSD) is heritable and a potential consequence of exposure to traumatic stress. Evidence suggests that a quantitative approach to PTSD phenotype measurement and incorporation of lifetime trauma exposure (LTE) information could enhance the discovery power of PTSD genome-wide association studies (GWASs). Methods: A GWAS on PTSD symptoms was performed in 51 cohorts followed by a fixed-effects meta-analysis (N = 182,199 European ancestry participants). A GWAS of LTE burden was performed in the UK Biobank cohort (N = 132,988). Genetic correlations were evaluated with linkage disequilibrium score regression. Multivariate analysis was performed using Multi-Trait Analysis of GWAS. Functional mapping and annotation of leading loci was performed with FUMA. Replication was evaluated using the Million Veteran Program GWAS of PTSD total symptoms. Results: GWASs of PTSD symptoms and LTE burden identified 5 and 6 independent genome-wide significant loci, respectively. There was a 72% genetic correlation between PTSD and LTE. PTSD and LTE showed largely similar patterns of genetic correlation with other traits, albeit with some distinctions. Adjusting PTSD for LTE reduced PTSD heritability by 31%. Multivariate analysis of PTSD and LTE increased the effective sample size of the PTSD GWAS by 20% and identified 4 additional loci. Four of these 9 PTSD loci were independently replicated in the Million Veteran Program. Conclusions: Through using a quantitative trait measure of PTSD, we identified novel risk loci not previously identified using prior case-control analyses. PTSD and LTE have a high genetic overlap that can be leveraged to increase discovery power through multivariate methods.publishersversionpublishe
Relationship between stressfulness of claiming for injury compensation and long-term recovery: A prospective cohort study
Sleep Disturbance Immediately Prior to Trauma Predicts Subsequent Psychiatric Disorder
Study Objectives: This study investigated the extent to which sleep disturbance in the period immediately prior to a traumatic event predicted development of subsequent psychiatric disorder. Design: Prospective design cohort study Setting: Four major trauma hospitals across Australia Patients: A total of 1033 traumatically injured patients were initially assessed during hospital admission and followed up at 3 months (898) after injury Measures: Lifetime psychiatric disorder was assessed in hospital with the Mini-International Neuropsychiatric Interview. Sleep disturbance in the 2 weeks prior to injury was also assessed using the Sleep Impairment Index. The prevalence of psychiatric disorder was assessed 3 months after traumatic injury. Results: There were 255 (28%) patients with a psychiatric disorder at 3 months. Patients who displayed sleep disturbance prior to the injury were more likely to develop a psychiatric disorder at 3 months (odds ratio: 2.44, 95% CI: 1.62–3.69). In terms of patients who had never experienced a prior disorder (n = 324), 96 patients (30%) had a psychiatric disorder at 3 months, and these patients were more likely to develop disorder if they displayed prior sleep disturbance (odds ratio: 3.16, 95% CI: 1.59–4.75). Conclusions: These findings provide evidence that sleep disturbance prior to a traumatic event is a risk factor for development of posttraumatic psychiatric disorder.Richard A.

Skills Training in Affective and Interpersonal Regulation for Refugees Integrated With Narrative Exposure Therapy: A Case Study on the Treatment of PTSD and Emotion Dysregulation for Refugees and Asylum-Seekers
Tissue A, Specker P, Hoffman J, et al. Skills Training in Affective and Interpersonal Regulation for Refugees Integrated With Narrative Exposure Therapy: A Case Study on the Treatment of PTSD and Emotion Dysregulation for Refugees and Asylum-Seekers. Clinical Case Studies . 2022.The prevalence of post-traumatic stress disorder (PTSD) in individuals affected by war and conflict is high, with approximately 1 in 3 refugees and asylum-seekers meeting diagnostic criteria for PTSD. PTSD in refugees and asylum-seekers is associated with significant emotion dysregulation which may arise from chronic trauma exposure and post-migration stressors and lead to impaired day-to-day functioning. There is evidence that treatments that target emotion regulation skills prior to implementing exposure-based therapies lead to improved treatment response and reduced attrition in survivors of interpersonal traumas such as sexual abuse. The current case study details the use of a novel adaptation of one such treatment - Skills Training in Affective and Interpersonal Regulation for refugees and asylum-seekers (STAIR-R). In this case study, we report on the implementation of STAIR-R in combination with Narrative Exposure Therapy (NET) with Sara, a 60-year-old Iraqi woman who presented with high levels of nightmares, avoidance and emotion dysregulation following exposure to war- and conflict-related trauma and post-migration stressors. In this case study, we explore the intersection of emotion regulation skills training (in STAIR-R) and exposure therapy (in NET), and the potential for this combined intervention to improve emotion regulation skills, enhance coping with post-migration stressors and facilitate engagement with exposure-based treatment for PTSD
The long-term mental health impact of peacekeeping:Prevalence and predictors of psychiatric disorder
BACKGROUND: The mental health outcomes of military personnel deployed on peacekeeping missions have been relatively neglected in the military mental health literature. AIMS: To assess the mental health impacts of peacekeeping deployments. METHOD: In total, 1025 Australian peacekeepers were assessed for current and lifetime psychiatric diagnoses, service history and exposure to potentially traumatic events (PTEs). A matched Australian community sample was used as a comparator. Univariate and regression analyses were conducted to explore predictors of psychiatric diagnosis. RESULTS: Peacekeepers had significantly higher 12-month prevalence of post-traumatic stress disorder (16.8%), major depressive episode (7%), generalised anxiety disorder (4.7%), alcohol misuse (12%), alcohol dependence (11.3%) and suicidal ideation (10.7%) when compared with the civilian comparator. The presence of these psychiatric disorders was most strongly and consistently associated with exposure to PTEs. CONCLUSIONS: Veteran peacekeepers had significant levels of psychiatric morbidity. Their needs, alongside those of combat veterans, should be recognised within military mental health initiatives. DECLARATION OF INTEREST: None.
