Assessment of Sleep Disturbance as a Biomarker of Disease Activity in a Military Population With...
Post-traumatic Stress DisorderPost-Traumatic Stress Disorder (PTSD) is a public health problem due to both its chronic nature and the low response rate to conventional therapies. Sleep disorders are the first cause of complaint in patients with PTSD due to night awakenings, difficulty to fall asleep and nightmares. According to a part of the scientific community, replicative traumatic nightmares represent PTSD's basis mechanism. Traumatic nightmares generate disabling symptoms such as anxiety reactions, while maintaining the symptoms by depriving the individual of good quality sleep. Traumatic nightmares may thus be a sign of PTSD seriousness and chronicity, although their physiological basis remain poorly known. In the military population, which is highly exposed to psychological traumatism, PTSD prevalence is very high and is associated with severe intensity patterns, a very high frequency of replicative nightmares and a low response to conventional therapies.
Psychological Effect of Explicit Recall After Sedation (PEERS)
AwarenessAnesthesia2 moreAwareness, or explicit recall, under sedation is often intended and expected by anesthesiologists and is assumed that does not associate with any sequelae. Thus, awareness under sedation is a common event and is estimated to occur in around one-quarter of patients in our population. However, two recent registry studies suggested some patients with awareness under sedation have comparable psychological sequelae to those patients with awareness during general anesthesia. As such, we plan to conduct a a single center, prospective cohort study to evaluate the incidence, experience and psychological consequence of awareness under sedation. In this study, we will prospectively include 2500 patients who will be scheduled to have major joint replacement surgery under regional anesthesia and sedation at University Hospital, London Health Sciences Center. All participants will be assessed at four separate time points including: Enrollment/Surgical Preparatory Area (~ 2 hours before surgery) Post Anesthesia Care Unit (or up to 6 hours after surgery) Postoperative day one (in hospital) Postoperative 3 months (expected to be after discharge via telephone)
Study of the Association Between the Type of Attachment and the Risk of Post-Traumatic Stress Disorder...
Post-Traumatic Stress DisorderAttachment theory models the emotional bonding that is activated in situations of danger, via mental representations of self and others. Four types of attachment (TA) exist in adults: 3 insecure (Preoccupied, Detached, Fearful) and 1 secure. Attachment type is a major factor in the development of Post-Traumatic Stress Disorder (PTSD), a frequent and disabling mental disorder that occurs after a traumatic event. A meta-analysis based on Anglo-Saxon studies including various populations (general, military or clinical) (n=9268 patients) suggested an association between Fearful BP and high level of PTSD symptoms (r=0.44). Nevertheless, these results did not allow the identification of variations related to the individual risk factors (RDFs) of the subject and his environment, especially in the French socio-cultural context. The investigators propose to study the association between LDs and the risk of PTSD in the days following exposure, their mutual influence in the months following, and their associated factors. Thus, a prospective cohort study among French adult victims of a traumatic event could objectify the link between BP - as close as possible to the event - and the risk of PTSD.
Effect of Baclofen to Prevent Post-Traumatic Stress Disorder
AlcoholismPost Traumatic Stress DisorderConsidering the results of the Baclorea study (10% reduction in episodes of agitation in intensive care in the Baclofen group), the investigators would like to know whether this reduction in agitation also results in a reduction in the incidence of the syndrome of long-term post-traumatic stress (5 years later). The investigators wish to contact by telephone, blinded from the randomization group as defined in the framework of the Balorea project, by telephone contact, the patients who had been included in the Balorea study between June 2016 and February 2019.
Biological Markers for Post-Traumatic Stress Disorder
Post Traumatic Stress DisorderThe current study aims to evaluate the sensitivity and specificity of a combination of various objective biomarkers for the diagnosis of PTSD.
RCT for Innovating Stress-related eHealth
Posttraumatic Stress DisorderSexual Assault1 moreThe Randomized Control Trial for Innovating Stress-related eHealth (RISE) Study tests the hypotheses that a highly promising digital therapeutic (RISE Guide) targeting anxiety sensitivity (AS) will be acceptable to women sexual assault survivors; reduce survivors' anxiety sensitivity, and, in turn, posttraumatic stress. If successful, RISE Guide could be provided at no cost to all women who present to US emergency departments for emergency care after sexual assault.
Optimizing Cognitive Remediation
SchizophreniaStress Disorders1 moreVeterans with mental illness face challenges with community reintegration, including achieving vocational success, attaining their educational goals and going back to school, and maintaining a high quality of life. VA Mental Health Residential Rehabilitation Treatment Programs, Psychosocial Rehabilitation and Recovery Centers and other mental health treatment programs are designed to help Veterans overcome these barriers, but cognitive impairment often seen in Veterans with mental illness limits gains from these settings. Cognitive remediation interventions can be helpful, but they are either "one-size fits all," and thus may not be useful for all Veterans with mental illness, or are too narrow in scope, focusing on specific mental illnesses, limiting generalizability. This project will test whether an objective neurophysiological biomarker, mismatch negativity (MMN), can better match the "right" Veteran to the "right" cognitive remediation treatment regardless of their specific mental health diagnosis.
An Evaluation of Two PTSD Assessments in an Active Duty and Military Veteran Sample
Stress DisordersPost-TraumaticGiven the high prevalence of post-traumatic stress disorder (PTSD) in veterans and active duty military, the focus of this research study is to test the reliability of two new PTSD assessments, the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Symptom Scale Interview for DSM-5 (PSSI-5) and compare the results between the two new assessments and the previous "gold standard", the Clinician Administered PTSD Scale for DSM-IV (CAPS-IV). Biomarkers believed to be related to PTSD (e.g., biofluid biomarkers, cognitive and physiological markers, and neural activity as measured by EEG) will be collected to inform targeted interventions in specific groups of patients and other large-scale biomarker discovery efforts in the field. Participants will be 950 male and female active duty military and veterans ages 18 or older who have been exposed to at least one traumatic event.
Improving FAMily Members' Experience in the ICU
Stress DisordersPost-Traumatic1 moreThe aim of the present research is to set up a large multicentric, prospective cohort of family members of patients admitted to intensive care. The data collected will concern the patients and their family members, the caregivers and the functioning of the services during the collection period. This cohort will allow: to carry out a quantitative evaluation of post-traumatic stress disorder (PTSD) in a large number of family members, to determine the risk factors in relation to the characteristics of the family members, and to define a predictive model of PTSD in this population to determine the factors related to the operating conditions of the resuscitation services that favor the occurrence of PTSD in the family members, to create a biological bank from blood samples taken from family members, to carry out a qualitative study allowing a psychological and sociological analysis of the experience of the family members concerning the hospitalization in intensive care of their loved one.
Prevalence of Post-traumatic Stress Disorder and Trauma Symptoms in a General Population Sample...
Post-traumatic Stress DisorderPsychological TraumaThe goal of this observational study is to learn about how many people have post-traumatic stress disorder and related symptoms in the general population of people without any mental illness in the Barcelona region of Catalonia, Spain. The main questions it aims to answer are: What is the prevalence of post-traumatic stress disorder in a sample of healthy controls without other mental disorders? What is the prevalence of trauma-related symptoms in a sample of healthy controls without mental illness? What is the prevalence of dissociative symptoms (including symptoms of depersonalisation and somatoform dissociation) in a sample of healthy controls without mental illness? What is the prevalence of recent and childhood traumatic life events in a sample of healthy controls without mental illness? What is the prevalence of difficulties in psychosocial functioning in healthy controls without mental illness? What is the prevalence of depressive symptoms in healthy controls without mental illness? What is the prevalence of general psychiatric symptoms in healthy controls without mental illness? Participants will be asked to take part in an online screening programme, and then to come to an interview with a clinician who will apply validated scales to test the above.
