Post-traumatic stress disorder and incident fractures in the Danish population.

ABSTRACT: Psychological stress may be associated with increased risk of fractures. It is unknown whether post-traumatic stress disorder (PTSD), a marker of chronic severe psychological stress occurring in response to a traumatic event, influences fracture risk. In this nationwide cohort study, persons with PTSD had an increased risk of fractures compared to the general population.

Introduction

We conducted a population-based national cohort study in Denmark to examine the association between PTSD and incident fractures.

Methods

We examined the incidence rate of overall and specific fractures among patients with clinician-diagnosed PTSD (n = 4114), compared with the incidence rate in the general population from 1995 to 2013, using Danish medical registry data. We further examined differences in associations by gender, age, psychiatric and somatic comorbidity, and follow-up time. We calculated absolute risks, standardized incidence ratios (SIRs), and 95% confidence intervals (95% CIs).

Results

Risk of any fracture among persons with PTSD was 24% (95% CI 20%, 28%) over the study period. The SIR for any fracture was 1.7 (95% CI 1.6, 1.9). We found little evidence of effect measure modification of the association between PTSD and fractures in our stratified analyses.

Conclusions

Our findings suggest that PTSD is associated with increased fracture risk.

Neuroepigenetics of Post-Traumatic Stress Disorder.

Project description:While diagnosis of PTSD is based on behavioral symptom clusters that are most directly associated with brain function, epigenetic studies of PTSD in humans to date have been limited to peripheral tissues. Animal models of PTSD have been key for understanding the epigenetic alterations in the brain most directly relevant to endophenotypes of PTSD, in particular those pertaining to fear memory and stress response. This chapter provides an overview of neuroepigenetic studies based on animal models of PTSD, with an emphasis on the effect of stress on fear memory. Where relevant, we also describe human-based studies with relevance to neuroepigenetic insights gleaned from animal work and suggest promising directions for future studies of PTSD neuroepigenetics in living humans that combine peripheral epigenetic measures with measures of central nervous system activity, structure and function.

Incident psychiatric comorbidity following stress disorder diagnoses in Danish school-aged children: prospective population-based study.

Project description:BackgroundProspective population-based studies of psychiatric comorbidity following trauma and severe stress exposure in children are limited.AimsTo examine incident psychiatric comorbidity following stress disorder diagnoses in Danish school-aged children using Danish national healthcare system registries.MethodChildren (6-15 years of age) with a severe stress or adjustment disorder (ICD-10) between 1995 and 2011 (n = 11 292) were followed prospectively for an average of 5.8 years. Incident depressive, anxiety and behavioural disorder diagnoses were examined relative to an age- and gender-matched comparison cohort (n = 56 460) using Cox proportional hazards regression models. Effect modification by gender was examined through stratified analyses.ResultsAll severe stress and adjustment disorder diagnoses were associated with increased rates for all incident outcome disorders relative to the comparison cohort. For instance, adjustment disorders were associated with higher rates of incident depressive (rate ratio RR = 6.8; 95% CI 6.0-7.7), anxiety (RR = 5.3; 95% CI 4.5-6.4), and behavioural disorders (RR = 7.9; 95% CI 6.6-9.3). Similarly, PTSD was also associated with higher rates of depressive (RR = 7.4; 95% CI 4.2-13), anxiety (RR = 7.1; 95% CI 3.5-14) and behavioural disorder (RR = 4.9; 95% CI 2.3-11) diagnoses. There was no evidence of gender-related differences.ConclusionsStress disorders varying in symptom constellation and severity are associated with a range of incident psychiatric disorders in children. Transdiagnostic assessments within a longitudinal framework are needed to characterise the course of post-trauma or severe stressor psychopathology.

Post-traumatic stress disorder symptoms in COVID-19 survivors: online population survey.

Project description:This study examined post-traumatic stress disorder (PTSD) symptoms in 13 049 survivors of suspected or confirmed COVID-19, from the UK general population, as a function of severity and hospital admission status. Compared with mild COVID-19, significantly elevated rates of PTSD symptoms were identified in those requiring medical support at home (effect size 0.178 s.d., P = 0.0316), those requiring hospital admission without ventilation (effect size 0.234 s.d., P = 0.0064) and those requiring hospital admission with ventilator support (effect size 0.454 s.d., P < 0.001). Intrusive images were the most prominent elevated symptom. Adequate psychiatric provision for such individuals will be of paramount importance.

POST-TRAUMATIC STRESS DISORDER IN POLY-TRAUMA CASES.

Project description:Six hundred and one patients, who sustained injuries in militant activities, admitted during a 7 month period to a zonal referral hospital were studied. The majority, 54.6% from the Armed Forces and 38.8% from the para-military forces, were in the age group of 22-53 years. There were 40 (6.7%) civilian casualties. These were in the age group of 20-45 years. A large number (75.7%) of the casualties manifested with post-traumatic stress symptoms. 24.3% of them were rated as post-traumatic stress disorder. Six months follow-up revealed persistence of post-traumatic stress disorder in 17.1% of the cases. By one year, 42.1% who responded to the follow-up letters had persistence of post-traumatic stress disorder in 4.95%. Early recognition of this psychic trauma and preventive strategies are discussed.

Post-traumatic stress disorder and cardiovascular disease.

Project description:In this paper, a first in a Series of two, we look at the evidence for an association of post-traumatic stress disorder with incident cardiovascular disease risk and the mechanisms that might cause this association, as well as the prevalence of post-traumatic stress disorder due to cardiovascular disease events and its associated prognostic risk. We discuss research done after the publication of previous relevant systematic reviews, and survey currently funded research from the two most active funders in the field: the National Institutes of Health and the US Veterans Administration. We conclude that post-traumatic stress disorder is a risk factor for incident cardiovascular disease, and a common psychiatric consequence of cardiovascular disease events that might worsen the prognosis of the cardiovascular disease. There are many candidate mechanisms for the link between post-traumatic stress disorder and cardiovascular disease, and several ongoing studies could soon point to the most important behavioural and physiological mechanisms to target in early phase intervention development. Similarly, targets are emerging for individual and environmental interventions that might offset the risk of post-traumatic stress disorder after cardiovascular disease events.

Post-traumatic Stress Disorder Post Partum: The Impact of Birth on the Prevalence of Post-traumatic Stress Disorder (PTSD) in Multiparous Women.

Project description:Traumatic birth experiences may lead to serious psychological impairment. Recent studies show that a considerable number of women can develop post-traumatic stress disorder (PTSD), in some cases in a subsyndromal form. Until now, the possibility that postpartum psychological symptoms might be a continuum of a pre-existing disorder in pregnancy has rarely been considered. This study therefore aimed to evaluate the proportion of women who develop post-traumatic stress disorder as a result of childbirth. Materials and Methods: 56 multiparous women were recruited for the study. The diagnosis of PTSD was made according to the criteria for psychological disorders in the DSM-IV (Diagnostics and Statistical Manual of Mental Disorders). The data were collected in structured interviews in the 30th to 38th week of gestation and in the 6th week post partum. Results: Of the 56 women participating, 52 (93?%) completed the survey. Uncontrolled results showed that 21.15?% of the multiparous women met the full diagnostic PTSD criteria in the 6th week post partum. After the exclusion of all cases already characterised by all criteria or a subsyndromal form of PTSD caused by previous traumatisation, the PTSD rate was below 8?% at 6 weeks postpartum (=?incidence rate of PTSD post partum). Conclusions: The present study is the first prospective longitudinal study to demonstrate the occurrence of full criteria PTSD in multiparous women as a result of childbirth after having excluded pre-existing PTSD. The results of our study show a high prevalence rate of PTSD during pregnancy. A number of women report all aspects of post-traumatic stress disorder as a result of childbirth.

Relationships among Trait Resilience, Virtues, Post-traumatic Stress Disorder, and Post-traumatic Growth.

Project description:The present study aims to examine the relationship between trait resilience and virtues in the context of trauma. A total of 537 participants who attended the preliminary investigation and completed the Life Events Checklist were screened. Of these participants, 142 suffered from personal traumatic experiences in the past year; these individuals were qualified and invited to respond to online questionnaires to assess trait resilience, virtues (i.e., Conscientiousness, Vitality, and Relationship), post-traumatic stress disorder (PTSD) symptoms, and post-traumatic growth (PTG). The following questionnaires were used: Connor-Davidson Resilience Scale-Revised, Chinese Virtues Questionnaire, PTSD Checklist-Specific, and Post-traumatic Growth Inventory-Chinese. Only 95 participants who manifested self-reported PTSD symptoms and PTG were involved in the current analyses. Trauma was positively and significantly correlated with PTSD in the current sample. Results indicated that trait resilience was positively associated with virtues and PTG; by contrast, PTSD scores were negatively but not significantly related to most of these factors. The three virtues contributed to PTG to a greater extent than trait resilience in non-PTSD and PTSD groups. However, trait resilience remained a significant predictor in the PTSD group even when the three virtues were controlled. The relationship between trait resilience and PTG was moderated by PTSD type (non-PTSD group vs. PTSD group). Our results further suggested that trait resilience and virtues were conceptually related but functionally different constructs. Trait resilience and virtues are positively related; thus, these factors contributed variances to PTG in the context of trauma; however, trait resilience is only manifested when virtues are controlled and when individuals are diagnosed as PTSD. Furthermore, implications and limitations of this study are discussed.

Post-traumatic stress disorder following disasters: a systematic review.

Project description:Disasters are traumatic events that may result in a wide range of mental and physical health consequences. Post-traumatic stress disorder (PTSD) is probably the most commonly studied post-disaster psychiatric disorder. This review aimed to systematically assess the evidence about PTSD following exposure to disasters. MethodA systematic search was performed. Eligible studies for this review included reports based on the DSM criteria of PTSD symptoms. The time-frame for inclusion of reports in this review is from 1980 (when PTSD was first introduced in DSM-III) and February 2007 when the literature search for this examination was terminated.We identified 284 reports of PTSD following disasters published in peer-reviewed journals since 1980. We categorized them according to the following classification: (1) human-made disasters (n=90), (2) technological disasters (n=65), and (3) natural disasters (n=116). Since some studies reported on findings from mixed samples (e.g. survivors of flooding and chemical contamination) we grouped these studies together (n=13).The body of research conducted after disasters in the past three decades suggests that the burden of PTSD among persons exposed to disasters is substantial. Post-disaster PTSD is associated with a range of correlates including sociodemographic and background factors, event exposure characteristics, social support factors and personality traits. Relatively few studies have employed longitudinal assessments enabling documentation of the course of PTSD. Methodological limitations and future directions for research in this field are discussed.

Genetic approaches to understanding post-traumatic stress disorder.

Project description:Post-traumatic stress disorder (PTSD) is increasingly recognized as both a disorder of enormous mental health and societal burden, but also as an anxiety disorder that may be particularly understandable from a scientific perspective. Specifically, PTSD can be conceptualized as a disorder of fear and stress dysregulation, and the neural circuitry underlying these pathways in both animals and humans are becoming increasingly well understood. Furthermore, PTSD is the only disorder in psychiatry in which the initiating factor, the trauma exposure, can be identified. Thus, the pathophysiology of the fear and stress response underlying PTSD can be examined and potentially interrupted. Twin studies have shown that the development of PTSD following a trauma is heritable, and that genetic risk factors may account for up to 30-40% of this heritability. A current goal is to understand the gene pathways that are associated with PTSD, and how those genes act on the fear/stress circuitry to mediate risk vs. resilience for PTSD. This review will examine gene pathways that have recently been analysed, primarily through candidate gene studies (including neuroimaging studies of candidate genes), in addition to genome-wide associations and the epigenetic regulation of PTSD. Future and on-going studies are utilizing larger and collaborative cohorts to identify novel gene candidates through genome-wide association and other powerful genomic approaches. Identification of PTSD biological pathways strengthens the hope of progress in the mechanistic understanding of a model psychiatric disorder and allows for the development of targeted treatments and interventions.
