Development Of Posttraumatic Stress Disorder Research Articles

A Neuroanatomic and Pathophysiologic Framework for Novel Pharmacological Approaches to the Treatment of Post-traumatic Stress Disorder.

Post-traumatic stress disorder (PTSD) is a debilitating disorder inflicting high degrees of symptomatic and socioeconomic burdens. The development of PTSD results from a cascade of events with contributions from multiple processes and the underlying pathophysiology is complex, involving neurotransmitters, neurocircuitry, and neuroanatomical pathways. Presently, only two medications are US FDA-approved for the treatment of PTSD, both selective serotonin reuptake inhibitors (SSRIs). However, the complex underlying pathophysiology suggests a number of alternative pathways and mechanisms that may be targets for potential drug development. Indeed, investigations and drug development are proceeding in a number of these alternative, non-serotonergic pathways in an effort to improve the management of PTSD. In this manuscript, the authors introduce novel and emerging treatments for PTSD, including drugs in various stages of development and clinical testing (BI 1358894, BNC-210, PRAX-114, JZP-150, LU AG06466, NYV-783, PH-94B, SRX246, TNX-102), established agents and known compounds being investigated for their utility in PTSD (brexpiprazole, cannabidiol, doxasoin, ganaxolone, intranasal neuropeptide Y, intranasal oxytocin, tianeptine oxalate, verucerfont), and emerging psychedelic interventions (ketamine, MDMA-assisted psychotherapy, psilocybin-assisted psychotherapy), with an aim to examine and integrate these agents into the underlying pathophysiological frameworks of trauma-related disorders.

Potential causal association between gut microbiome and posttraumatic stress disorder

BackgroundThe causal effects of gut microbiome and the development of posttraumatic stress disorder (PTSD) are still unknown. This study aimed to clarify their potential causal association using mendelian randomization (MR).MethodsThe summary-level statistics for gut microbiome were retrieved from a genome-wide association study (GWAS) of the MiBioGen consortium. As to PTSD, the Freeze 2 datasets were originated from the Psychiatric Genomics Consortium Posttraumatic Stress Disorder Working Group (PGC-PTSD), and the replicated datasets were obtained from FinnGen consortium. Single nucleotide polymorphisms meeting MR assumptions were selected as instrumental variables. The inverse variance weighting (IVW) method was employed as the main approach, supplemented by sensitivity analyses to evaluate potential pleiotropy and heterogeneity and ensure the robustness of the MR results. We also performed reverse MR analyses to explore PTSD’s causal effects on the relative abundances of specific features of the gut microbiome.ResultsIn Freeze 2 datasets from PGC-PTSD, eight bacterial traits revealed a potential causal association between gut microbiome and PTSD (IVW, all P < 0.05). In addition, Genus.Dorea and genus.Sellimonas were replicated in FinnGen datasets, in which eight bacterial traits revealed a potential causal association between gut microbiome and the occurrence of PTSD. The heterogeneity and pleiotropy analyses further supported the robustness of the IVW findings, providing additional evidence for their reliability.ConclusionOur study provides the potential causal impact of gut microbiomes on the development of PTSD, shedding new light on the understanding of the dysfunctional gut-brain axis in this disorder. Our findings present novel evidence and call for investigations to confirm the association between their links, as well as to illuminate the underlying mechanisms.

The role of environmental sensitivity in post-traumatic stress symptoms in Lebanese children and adolescents.

Children differ substantially in their sensitivity to the quality of their environment. Some are more sensitive and more likely to develop Post-Traumatic Stress Disorder (PTSD) in response to Childhood Adversities (CAs), but might also benefit more from Positive Home Experiences (PHE). The aim of this study is to investigate the role of Environmental Sensitivity (ES), CAs and PHEs in PTSD development in children and adolescents. Data was collected from N = 2,569 children/adolescents. PTSD symptoms, CAs, PHEs and ES were assessed with self-report measures. We found that higher ES and CAs emerged as risk factors for PTSD development whereas higher levels of PHEs protected against PTSD. ES moderated the effects of CAs (β = 1.08, p < .001) on PTSD symptoms in the total sample. This moderating effect was more pronounced in girls, suggesting that highly sensitive girls with high childhood adversities were more likely to have higher PTSD symptoms than girls with low levels of sensitivity (β = 1.09, p < .001). In conclusion, Environmental Sensitivity played an important role as a risk factor for PTSD and as a moderating factor that accentuated the main effects of childhood adversities, particularly in girls.

The role of self-criticism and self-compassion in the development of PTSD among midwives

ObjectiveHealthcare providers might develop emotional distress following direct and indirect exposure to traumatic events. Evidence shows that midwives, who care for women in complicated situations, are often exposed to circumstances that have a potential to lead to a variety of psychological reactions, including symptoms identified with post-traumatic stress disorder (PTSD). Nevertheless, the positive-healthy context in which childbirth is mainly perceived raises questions regarding the protective role of personality traits, which are related to processing methods of stress and pain, in the development of PTSD among this unique population. This study aimed to explore the associations between traits such as self-compassion, self-criticism, resilience, cognitive thinking, and pain catastrophizing and PTSD symptoms among Israeli midwives. SettingUsing a quantitative cross-sectional study,123 midwives from ten hospitals in Israel anonymously reported their characteristics and severity of stress and/or PTSD symptoms by filling out the Psychopathy Checklist questionnaire. Analysis of personality traits was performed via the following questionnaires: Self-Compassion Scale - Short Form, Depressive Experiences Questionnaire - Self Criticism, and the Connor-Davidson Resilience Scale. Additionally, we measured the level of catastrophizing pain by employing the Pain Catastrophizing Scale questionnaire. FindingsMost of the midwives reported existing post-trauma symptoms, among them 11.38% had been diagnosed with PTSD. Severity of the PTSD correlated with their self-criticism and the pain catastrophizing rates. Additional examination of the involvement of personality traits showed that midwives with high self-criticism, low mental resilience, besides a high rate of pain catastrophizing, were more vulnerable to developing PTSD. ConclusionsThe findings can help to refine the understanding regarding the involvement of midwives' personality characteristics in the process of PTSD onset. Vulnerable midwives have been identified as those at risk to develop PTSD symptoms. Implications for practiceThe clinical significance of these insights is to promote the ability to identify midwives who are at risk to develop PTSD. Furthermore, this information might help to produce training programs and a support network to empower self-compassion and mental resilience, and to minimize self-criticism in order establish a support network, which would help to deal with the difficult experiences they face at work.

Meta-analysis of risk factors for posttraumatic stress disorder in myocardial infarction.

The aim of this study was to identify the risk factors for posttraumatic stress disorder in patients with myocardial infarction. Cohort, case-control, and cross-sectional studies on posttraumatic stress disorder (PTSD) in patients with myocardial infarction were searched from PubMed, Embase, Cochrane Library, Web of Science, China Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and Technology Journal database. The Newcastle-Ottawa Quality Assessment Scale was used to score the quality of the included literature in the cohort and case-control studies, and the cross-sectional studies were scored using the American Agency for Health Care Quality and Research cross-sectional study quality evaluation criteria. The literature was screened independently by 2 researchers, and if there was no consensus, the inclusion was decided by a third party. The extraction content included first author, publication year, sample size, PTSD assessment tool, PTSD assessment time, PTSD incidence, influencing factors, and study type. Meta-analysis of data was performed using Stata17.0 software. Ten studies were included, including 2 cohort studies, 7 cross-sectional studies, and 1 case-control study, with a total sample size of 2371 patients, including 26 influencing factors. The results of meta-analysis showed that the prevalence of PTSD in patients with myocardial infarction was 21.2%. Statistically significant influencing factors were gender (odd ratio [OR] = 3.124), neuroticism score (OR = 2.069), and age (OR = 0.913). The prevalence of PTSD in patients with myocardial infarction in China is higher than that in other countries. Female and neurotic personality are risk factors for developing PTSD in patients with myocardial infarction, and old age is protective factor for developing PTSD in patients with myocardial infarction. Targeted measures should be taken to prevent and reduce the occurrence and development of PTSD in patients with myocardial infarction in the future.

Anxiety sensitivity, finding the body, and posttraumatic stress disorder in suicide-bereaved treatment-seeking adults.

Those bereaved by suicide are at greater risk of prolonged distress compared to those bereaved by other modes of death. Trauma- and emotion-related factors may increase this vulnerability. Finding the body of the deceased may intensify postsuicide distress. Anxiety sensitivity, fear of one's anxiety-related symptoms, has been positively associated with posttraumatic stress disorder (PTSD) in other trauma populations but has not been studied in the suicide bereaved. This study examined the relationships among finding the body, anxiety sensitivity, and PTSD in a treatment-seeking, suicide-bereaved sample (N = 50). Pretreatment baseline data on demographics, the Anxiety Sensitivity Index, and the PTSD Checklist were analyzed. Younger age (r = -.31, p = .03), being a person of color (r = -.32, p = .02), and fewer days since the loss (r = -.30, p = .03) were associated with greater PTSD. Controlling for age, race, and days since the loss, PTSD was unrelated to finding the body, F(1, 45) = 0.01, p = .92, but was positively associated with anxiety sensitivity (pr = .32, p = .03). In simultaneous regression analyses, age, race, days since the loss, finding the body, and anxiety sensitivity accounted for 33% of the variance in PTSD, F(2, 44) = 4.29, p = .003; anxiety sensitivity was the only significant predictor of PTSD symptoms (β = .36, t = 2.35, p = .02). Anxiety sensitivity has important implications for the development and maintenance of PTSD in the suicide bereaved and should be assessed and targeted in suicide postvention.

Attentional bias modification and attention control training in PTSD: a systematic review and meta-analysis.

Cognitive models of post-traumatic stress disorder (PTSD) highlighted the effect of maladaptive cognitive processing in the development and maintenance of PTSD. PTSD is related to attentional bias (AB) toward threatening stimuli and greater attentional bias variability (ABV). Attentional bias modification (ABM) and attention control training (ACT) have demonstrated the effect of improving PTSD, but the results of randomized controlled trials (RCTs) are controversial. The current study aimed to evaluate the extent of evidence supporting the efficacy of ABM in the treatment of PTSD. Systematic review and meta-analysis. We searched PUBMED, PsycINFO, EMBASE, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials for articles published between 1980 and 2022. RCTs of ABM for adult participants with PTSD symptoms were identified. The primary outcome was changes in PTSD severity, and the second outcome was changes in AB and ABV. Trial quality was assessed using the Cochrane Risk of Bias Tool. Publication bias was assessed using the Doi plot and Luis Furuya-Kanamori (LFK) index. Eight RCTs comparing the effect of ABM to ACT were included in the review, and six studies were meta-analyzed. Meta-analysis favored ACT in improving PTSD symptoms and ABV, and the effect size was large. ABM and ACT demonstrated similar effects in improving AB. ACT should not only be seen as a control training condition but also has therapeutic values. However, since the current meta-analysis only included a limited number of studies, further research was still needed to examine the clinical value of ACT in PTSD treatment.

The Association between COVID-19-Related Discrimination and Probable Post-Traumatic Stress Disorder among Patients with COVID-19 in Sapporo, Japan.

BackgroundDisasters such as earthquakes, terrorism, and pandemics have triggered post-traumatic stress disorder (PTSD), and discrimination against the affected individuals has been linked to the development of PTSD. However, there is limited evidence regarding the association between discrimination against coronavirus disease 2019 (COVID-19) patients and probable PTSD in Japan.MethodsWe conducted a cross-sectional study utilizing a web-based questionnaire targeting individuals who had contracted the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Sapporo City. A total of 4247 individuals with laboratory-confirmed SARS-CoV-2 infection spanning from February 2020 to February 2022 completed the questionnaire (response rate: 15.9%). Probable PTSD was measured using the three-item Posttraumatic Diagnostic Scale. The stratified exact logistic regression was applied to calculate the odds ratios (OR) of probable PTSD for COVID-19-related discrimination with adjusted factors.ResultsThis study included 3626 patients who had a history of SARS-CoV-2 infection. Among them, 321 patients (8.9%) experienced COVID-19-related discrimination. The prevalence of probable PTSD was 19.6% (63/321) among the patients who experienced COVID-19-related discrimination, and 4.6% (152/3305) among those who had not encountered such discrimination. The adjusted OR of COVID-19-related discrimination for probable PTSD was 4.68 (95% confidence interval [95% CI], 3.36-6.53). The population attributable fraction of probable PTSD attributable to COVID-19-related discrimination among COVID-19 patients was estimated to be 23.4% (95% CI, 21.5-25.3).ConclusionThe comprehensive epidemiological survey of COVID-19 patients in Japan showed that COVID-19-related discrimination was associated with a higher prevalence of probable PTSD. Mitigating discrimination could be helpful to attenuate PTSD in future pandemics.

Cognitive Models Explaining Post-Traumatic Stress Disorder and Cognitive Therapy Methods Frequently Used in Trauma Victims

Trauma is considered a significant event that causes intense fear and anxiety and frequent avoidance owing to its unfolding and persistence. Post-traumatic stress disorder (PTSD) may develop when the distress and symptoms caused by the development and acute nature of the trauma do not resolve spontaneously over time. Incompatibility with one's existing schemas and the emergence of new nonfunctional schemas are both effective in the development of PTSD. Thus, while working with trauma victims, attempts to restructure the existing traumatic cognitions by doing assessments about traumatic cognitions play an effective role in reinterpreting the traumatic experience. This review study examines the nature of trauma, the expression of trauma according to cognitive therapy, widely recognized cognitive models explaining trauma, and frequently utilized effective cognitive methods for trauma victims. The impact of cognitive processes on the development and continuation of trauma was expressed, and the models of different experts explaining trauma were discussed in detail. Furthermore, considering the contribution of cognitive therapy intervention techniques for PTSD in healthily reevaluating the trauma, cognitive therapy methods that are thought to contribute to both the victim and mental health professionals are included.

Children Fleeing War-Exploring the Mental Health of Refugee Children Arriving in Israel after the Ukraine 2022 Conflict

BackgroundIn February 2022, Ukraine suffered a devastating assault by Russia, leading to destruction, casualties, and mass displacement. Among those displaced were over 1.5 million children. Forced displacement exposes children to a heightened risk of mental health issues. ObjectiveThis study investigated the prevalence of Post-traumatic stress disorder (PTSD) and other mental health issues among child refugees shortly after their displacement from Ukraine to Israel. It aimed to identify factors influencing PTSD development and explore their associations. MethodsThe study included 59 child refugees who had arrived in Israel after fleeing the war in Ukraine. Parents completed self-report questionnaires to assess their children's mental health. ResultsOnly three children met the DSM diagnostic criteria for PTSD, with higher scores in the negative cognition and re-experiencing clusters. Over half of the children exhibited general mental health problems, with approximately 40 % showing internalizing problems, and 30 % showing externalizing problems. The study also found a significant comorbidity between PTSD symptoms and internalizing problems. Additionally, internalizing problems emerged as the sole significant predictor of PTSD levels when considering factors such as age, gender, economic status, parents' work status, internalizing problems, and externalizing problems. ConclusionsChild refugees frequently experience psychological distress, even if they do not meet the formal diagnostic criteria for PTSD. They often exhibit other distress symptoms, primarily internalizing problems, which can be challenging to detect. A deeper understanding of the challenges faced by refugee children can inform the development of targeted assistance programs and the recruitment and training of personnel in host countries.

Use of substances to cope predicts posttraumatic stress disorder symptom persistence: Investigating patterns of interactions between symptoms and its maintaining mechanisms.

Posttraumatic stress disorder (PTSD) remains a growing public health challenge across the globe and is associated with negative and persistent long-term consequences. The last decades of research have identified different mechanisms associated with the development and persistence of PTSD, including maladaptive coping strategies, cognitive and experiential avoidance, and positive and negative metacognitions. Despite these advances, little is known about how these different processes interact with specific PTSD symptoms, and how they influence each other over time at the within-person level. Leveraging a large (N > 1,800) longitudinal data set representative of the Norwegian population during the COVID-19 pandemic, this preregistered study investigated these symptom-process interactions over four assessment waves spanning an 8-month period. Our panel graphical vector autoregressive network model revealed the dominating role of substance use to cope in predicting higher levels of PTSD symptoms over time and increases in PTSD symptomatology within more proximal time windows (i.e., within 6 weeks). Threat monitoring was associated with increased suicidal ideation, while threat monitoring itself was increasing upon decreased avoidance behavior, greater presence of negative metacognitions, and higher use of substances to cope. Our findings speak to the importance of attending to different coping strategies, particularly the use of substances as a coping behavior in efforts to prevent PTSD chronicity upon symptom onset. We outline future directions for research efforts to better understand the complex interactions and temporal pathways leading up to the development and maintenance of PTSD symptomatology.

Analysis of Posttraumatic Stress Disorder Gene Expression Profiles in a Prospective, Community-Based Cohort

abstract: Posttraumatic stress disorder (PTSD) is a common and debilitating psychiatric disorder that may occur in individuals exposed to traumatic events such as accidents, interpersonal violence, war, combat, or natural disasters. Additionally, PTSD has been implicated in the development of a variety of chronic conditions, including cardiovascular and metabolic diseases, suggesting the biological alterations associated with the disorder can manifest as chronic diseases in those suffering from PTSD. The biological underpinnings of the disorder are not well understood. Gene expression studies can illuminate the complex physiology of PTSD reflecting the embodiment of trauma, that is, the process in which traumatic experiences in our social environments could potentially manifest in our body by genomic mechanisms. To date, gene expression studies that examine the whole transcriptome are scarce and limited to single-time-point assessments. Here we applied a transcriptome-wide gene expression screen with RNA-seq to whole blood samples from predominantly African American community-dwelling participants to elucidate the gene expression signatures associated with the development of PTSD. The study participants ( N = 72) comprised a trauma-exposed subsample of participants enrolled in a longitudinal, prospective cohort study of adults living in Detroit, Michigan. PTSD was assessed in a structured telephone interview, and whole blood samples were taken both before and after trauma exposure. Among the 72 study participants, 10 had PTSD at baseline and 21 developed it during the study. We found 45 differentially expressed genes associated with PTSD development with an estimated log2-fold change &gt; 1.5 at a nominal p -value of &lt;0.05. Six genes ( PAX6 , TSPAN7 , PXDN , VWC2 , SULF1 , and NFATC4 ) were also ubiquitously expressed in all brain regions. Longitudinal sampling provides a promising mean to elucidate the pathophysiology underlying the embodiment of trauma.

Islamic Therapy and Spiritual Emotional Freedom Technique (SEFT) Interventions in Reducing Post-Traumatic Stress Disorder (PTSD) for Survivors of Mount Semeru Eruption

This research aims to determine the effectiveness of Islamic and spiritual emotional freedom technique (SEFT) interventions in reducing the symptoms of post-traumatic stress disorder (PTSD) among the survivors of the Mount Semeru eruption. This research has three phases: 1) Mapping the PTSD levels among survivors (n = 250); 2) Randomly choosing the survivor with PTSD to engage in either intervention: Islamic therapy (n = 10), or SEFT (n = 12); 3) post-intervention interview to describe the PTSD state post-intervention (n = 3). The first phase employed the Impact of Event Scale-Revised (IES-R) to collect PTSD information among 250 survivors and then discovered that the mean of survivors’ PTSD levels was moderate. The second phase was executed using a two-group pretest-posttest design and then analysed using a Wilcoxon-signed rank test; it revealed that either group significantly reduced the PTSD level among the survivors. Furthermore, the post-test results of both groups displayed no significant discrepancy. The third phase qualitatively confirmed that the PTSD level among the survivors was reduced after the intervention. Moreover, aside from intervention results, the interview exhibited that internal and external factors also determined PTSD development. The implication of the finding will be discussed further.

Association of Cardiovascular Diseases With Post-Traumatic Stress Disorder: An Updated Review

The intricate relationship between post-traumatic stress disorder (PTSD) and cardiovascular disease (CVD) has garnered increasing attention due to its bidirectional impact and potential for significant health consequences. Epidemiological evidence suggests that PTSD may serve as a risk factor for incident CVD, while acute CVD events can trigger PTSD, subsequently increasing the risk of recurrent cardiovascular events. This dynamic interplay is characterized by the human stress response, disrupted behavioral and lifestyle factors, and potential physiological mechanisms. Notably, the immediate aftermath of a cardiovascular event presents a critical window for intervention, offering the possibility of preventing the development of PTSD and its associated physiological and behavioral sequelae. However, while candidate mechanisms linking PTSD and CVD have been identified, determining which mechanisms are most amenable to intervention remains a challenge. This article emphasizes the urgency of addressing key unanswered questions in this domain. Despite an evolving understanding of the association between PTSD and CVD, causal relationships remain to be firmly established. Comprehensive investigations into the intricate interplay of behavioral and biological mechanisms are essential for identifying precise targets for intervention. Innovations in research methodologies, including the exploration of PTSD symptom dynamics and their impact on cardiovascular function, hold the potential for identifying crucial intervention points. Drawing parallels from prior challenges in translating identified risk factors into effective interventions, the field must prioritize systematic investigations and early-phase intervention trials. By doing so, researchers and clinicians can potentially develop strategies to mitigate CVD risk in the context of PTSD and improve both cardiovascular and mental health outcomes.

Using experience sampling methodology (ESM) to improve our understanding of day-to-day intrusion frequency and related distress in survivors of trauma

Background and objectivesCognitive models of posttraumatic stress disorder (PTSD) suggest that appraisals of traumatic sequelae and subsequent distress drive the development and maintenance of PTSD. Posttraumatic research has relied heavily on macro-longitudinal designs, with weeks or months between assessments of trauma-related cognitions and symptoms. The present study uses experience sampling methodology (ESM) better understand the day-to-day experiences of trauma exposed individuals. MethodsOne-hundred trauma exposed adults reported their posttraumatic symptoms, interpretations, and behaviours four times a day over a 10-day ESM period. ResultsAs anticipated, within-person fluctuations in negative appraisals of intrusions and maladaptive coping strategies (e.g., thought suppression) were significantly positively associated with intrusion frequency and related distress. In all cases, the associations for negative appraisals and maladaptive coping were stronger with intrusion related distress than intrusion frequency. LimitationsThe observed contemporaneous associations only demonstrate that variables reliably fluctuated together and cannot indicate causality. ConclusionsThe findings demonstrate that day-to-day fluctuations in trauma related perceptions and sequelae are significant and should be explored alongside broader individual differences to advance our understanding of the development, maintenance, and treatment of PTSD.

Factors Associated with Obstetric Violence Implicated in the Development of Postpartum Depression and Post-Traumatic Stress Disorder: A Systematic Review.

Postpartum depression (PPD) and post-traumatic stress disorder (PTSD) continue to be prevalent, and disabling women with mental disorders and obstetric violence (OV) may be a trigger for them, particularly during maternity. We aimed to analyze the association between manifestations of OV with the development of PPD and PTSD during pregnancy, childbirth, and postpartum. This systematic review was based on the PRISMA 2020 statement and explored original articles published between 2012 and 2022. A total of 21 articles were included in the analysis, and bias was assessed by the Effective Public Health Practice Project's Quality Assessment Tool. The highest rate of PPD symptoms appeared in women under 20 years old, multiparous, and with low education levels. The higher PTSD ratio was present in women under 35 years, primiparous, and with secondary studies. The mode of labor (instrumental or C-section) was identified as a major risk factor of PPD, being mediator variables of the informal coercion of health professionals and dissatisfaction with newborn healthcare. Instead, partner support during labor and high satisfaction with healthcare during birth were protective factors. Regarding PTSD, the mode of labor, several perineal tears, and the Kristeller technique were risk factors, and loss of autonomy and coercion modulated PTSD symptomatology. The protective factors for PTSD were respect for the labor plan, adequate communication with health professionals, social support during labor, and the skin-to-skin procedure. This systematic review provides evidence that OV contributes to PPD and PTSD, being important in developing standardized tools to prevent it. This study recommends changes in maternal healthcare policies, such as individualized healthcare assistance, humanized pregnancy protocols, and women's mental health follow-up, and improvements in the methodological quality of future research.

Соматические проявления при посттравматическом стрессовом расстройстве

&lt;p style="text-align: justify;"&gt;The article provides an overview of modern foreign studies aimed at identifying somatic correlates of post-traumatic stress disorder (PTSD) in various categories of the population. It has been shown that post-traumatic stress disorder, in the vast majority of cases, is associated with various psychosomatic and somatic symptoms. Some researchers have put forward a hypothesis about a hereditary predisposition to the development of PTSD during extreme psychotraumatization (epigenetic approach): premorbid characteristics of the hypothalamic-pituitary-adrenal system can determine the body's response to extreme psychotraumatic effects. The largest number of studies have revealed the relationship of post-traumatic stress disorder with such somatic / psychosomatic types of pathology as cardiovascular diseases, sleep disorders, autonomic disorders, immune system dysfunction, neurological and pseudoneurological disorders. The description of the mechanisms of comorbidity of PTSD and somatic dysfunctions proposed by the authors is largely contradictory and does not, to date, clarify the cause-and-effect relationships in the formation of PTSD and somatic manifestations.&lt;/p&gt;

Mitochondrial dysfunction as a possible trigger of neuroinflammation at post-traumatic stress disorder (PTSD)

Post-traumatic stress disorder (PTSD) is a neuropsychiatric disorder that occurs in approximately 15% of people as a result of some traumatic events. The main symptoms are re-experiencing and avoidance of everything related to this event and hyperarousal. The main component of the pathophysiology of PTSD is an imbalance in the functioning of the hypothalamic-pituitary-adrenal axis (HPA) and development of neuroinflammation. In parallel with this, mitochondrial dysfunction is observed, as in many other diseases. In this review, we focus on the question how mitochondria may be involved in the development of neuroinflammation and its maintaining at PTSD. First, we describe the differences in the operation of the neuro-endocrine system during stress versus PTSD. We then show changes in the activity/expression of mitochondrial proteins in PTSD and how they can affect the levels of hormones involved in PTSD development, as well as how mitochondrial damage/pathogen-associated molecule patterns (DAMPs/PAMPs) trigger development of inflammation. In addition, we examine the possibility of treating PTSD-related inflammation using mitochondria as a target.

P020 Exploring the Roles of Individual Rapid Eye Movement Sleep Parameters in Emotional Memory Processing

Abstract Background Maladaptive emotional memory processing is thought to underpin intrusion symptoms experienced by individuals with post-traumatic stress disorder (PTSD). Curtailment of rapid eye movement sleep (REMS) impairs emotional memory consolidation (EMC) and is proposed to contribute to the development of PTSD. However, the effects of altered REMS quality remain less explored. The present study aims to investigate the potential ability of REM percentage, REM latency, and REMS fragmentation to predict EMC. Methods The study forms part of a larger study investigating the effects of suvorexant and temazepam on REMS and EMC. Healthy participants view a series of emotionally positive, negative and neutral images, undergo overnight polysomnography with a study drug or placebo, and are assessed for recognition 48 hours after viewing the images. REMS architecture metrics are derived from polysomnographic data. EMC is calculated based on signal detection theory (d′ = z(hit rate) − z(false alarm rate)). Results Data collection is ongoing with 11 participants’ data being collected. A one-way ANOVA reveals a main effect of valence, with positive and negative images being recognised better than the neutral (p(positive-neutral) = .039, p(negative-neutral) = .039). REMS parameters do not significantly predict EMC when accounting for image valence, possibly due to low statistical power. Discussion Given existing literature supporting the contribution of REMS on emotional memory processing, promoting high-quality REMS may help facilitate adaptive EMC. Further data is required to examine this effect.

Identification of Psycho-Socio-Judicial Trajectories and Factors Associated With Posttraumatic Stress Disorder in People Over 15 Years of Age Who Recently Reported Sexual Assault to a Forensic Medical Center: Protocol for a Multicentric Prospective Study Using Mixed Methods and Artificial Intelligence.

Sexual assault (SA) can lead to a range of adverse effects on physical, sexual, and mental health, as well as on one's social life, financial stability, and overall quality of life. However, not all people who experience SA will develop negative functional outcomes. Various risk and protective factors can influence psycho-socio-judicial trajectories. However, how these factors influence trauma adaptation and the onset of early posttraumatic stress disorder (PTSD) is not always clear. Guided by an ecological framework, this project has 3 primary objectives: (1) to describe the 1-year psycho-socio-judicial trajectories of individuals recently exposed to SA who sought consultation with a forensic practitioner; (2) to identify predictive factors for the development of PTSD during the initial forensic examination using artificial intelligence; and (3) to explore the perceptions, needs, and experiences of individuals who have been sexually assaulted. This longitudinal multicentric cohort study uses a mixed methods approach. Quantitative cohort data are collected through an initial questionnaire completed by the physician during the first forensic examination and through follow-up telephone questionnaires at 6 weeks, 3 months, 6 months, and 1 year after the SA. The questionnaires measure factors associated with PTSD, mental, physical, social, and overall functional outcomes, as well as psycho-socio-judicial trajectories. Cohort participants are recruited through their forensic examination at 1 of the 5 participating centers based in France. Eligible participants are aged 15 or older, have experienced SA in the last 30 days, are fluent in French, and can be reached by phone. Qualitative data are gathered through semistructured interviews with cohort participants, individuals who have experienced SA but are not part of the cohort, and professionals involved in their psycho-socio-judicial care. Bivariate and multivariate analyses will be conducted to examine the associations between each variable and mental, physical, social, and judicial outcomes. Predictive analyses will be performed using multiple prediction algorithms to forecast PTSD. Qualitative data will be integrated with quantitative data to identify psycho-socio-judicial trajectories and enhance the prediction of PTSD. Additionally, data on the perceptions and needs of individuals who have experienced SA will be analyzed independently to gain a deeper understanding of their experiences and requirements. This project will collect extensive qualitative and quantitative data that have never been gathered over such an extended period, leading to unprecedented insights into the psycho-socio-judicial trajectories of individuals who have recently experienced SA. It represents the initial phase of developing a functional artificial intelligence tool that forensic practitioners can use to better guide individuals who have recently experienced SA, with the aim of preventing the onset of PTSD. Furthermore, it will contribute to addressing the existing gap in the literature regarding the accessibility and effectiveness of support services for individuals who have experienced SA in Europe. This comprehensive approach, encompassing the entire psycho-socio-judicial continuum and taking into account the viewpoints of SA survivors, will enable the generation of innovative recommendations for enhancing their care across all stages, starting from the initial forensic examination.
