Prevention of Post-Traumatic Stress Disorder After Trauma: Current Evidence and Future Directions

Neurobiology and Treatment of Posttraumatic Stress Disorder

The recent worldwide surge of warfare and hostilities exposes increasingly large numbers of individuals to traumatic events, placing them at risk of developing posttraumatic stress disorder (PTSD) and challenging both clinicians and service delivery systems. This overview summarizes and updates the core knowledge of the genetic, molecular, and neural circuit features of the neurobiology of PTSD and advances in evidence-based psychotherapy, pharmacotherapy, neuromodulation, and digital treatments. While the complexity of the neurobiology and the biological and clinical heterogeneity of PTSD have challenged clinicians and researchers, there is an emerging consensus concerning the underlying mechanisms and approaches to diagnosis, treatment, and prevention of PTSD. This update addresses PTSD diagnosis, prevalence, course, risk factors, neurobiological mechanisms, current standard of care, and innovations in next-generation treatment and prevention strategies. It provides a comprehensive summary and concludes with areas of research for integrating advances in the neurobiology of the disorder with novel treatment and prevention targets.

Preventing posttraumatic stress disorder following childbirth: a systematic review and meta-analysis

OBJECTIVE

Women can develop posttraumatic stress disorder in response to experienced or perceived traumatic, often medically complicated, childbirth; the prevalence of these events remains high in the United States. Currently, no recommended treatment exists in routine care to prevent or mitigate maternal childbirth-related posttraumatic stress disorder. We conducted a systematic review and meta-analysis of clinical trials that evaluated any therapy to prevent or treat childbirth-related posttraumatic stress disorder.

DATA SOURCES

PsycInfo, PsycArticles, PubMed (MEDLINE), ClinicalTrials.gov, CINAHL, ProQuest, Sociological Abstracts, Google Scholar, Embase, Web of Science, ScienceDirect, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for eligible trials published through September 2023.

STUDY ELIGIBILITY CRITERIA

Trials were included if they were interventional, if they evaluated any therapy for childbirth-related posttraumatic stress disorder for the indication of symptoms or before posttraumatic stress disorder onset, and if they were written in English.

METHODS

Independent coders extracted the sample characteristics and intervention information of the eligible studies and evaluated the trials using the Downs and Black's quality checklist and Cochrane's method for risk of bias evaluation. Meta-analysis was conducted to evaluate pooled effect sizes of secondary and tertiary prevention trials.

RESULTS

A total of 41 studies (32 randomized controlled trials, 9 nonrandomized trials) were reviewed. They evaluated brief psychological therapies including debriefing, trauma-focused therapies (including cognitive behavioral therapy and expressive writing), memory consolidation and reconsolidation blockage, mother-infant-focused therapies, and educational interventions. The trials targeted secondary preventions aimed at buffering childbirth-related posttraumatic stress disorder usually after traumatic childbirth (n=24), tertiary preventions among women with probable childbirth-related posttraumatic stress disorder (n=14), and primary prevention during pregnancy (n=3). A meta-analysis of the combined randomized secondary preventions showed moderate effects in reducing childbirth-related posttraumatic stress disorder symptoms when compared with usual treatment (standardized mean difference, -0.67; 95% confidence interval, -0.92 to -0.42). Single-session therapy within 96 hours of birth was helpful (standardized mean difference, -0.55). Brief, structured, trauma-focused therapies and semi-structured, midwife-led, dialogue-based psychological counseling showed the largest effects (standardized mean difference, -0.95 and -0.91, respectively). Other treatment approaches (eg, the Tetris game, mindfulness, mother-infant-focused treatment) warrant more research. Tertiary preventions produced smaller effects than secondary prevention but are potentially clinically meaningful (standardized mean difference, -0.37; -0.60 to -0.14). Antepartum educational approaches may help, but insufficient empirical evidence exists.

CONCLUSION

Brief trauma-focused and non-trauma-focused psychological therapies delivered early in the period following traumatic childbirth offer a critical and feasible opportunity to buffer the symptoms of childbirth-related posttraumatic stress disorder. Future research that integrates diagnostic and biological measures can inform treatment use and the mechanisms at work.

Early pharmacological interventions for prevention of post-traumatic stress disorder (PTSD) in individuals experiencing acute traumatic stress symptoms

BACKGROUND

Acute traumatic stress symptoms may develop in people who have been exposed to a traumatic event. Although they are usually self-limiting in time, some people develop post-traumatic stress disorder (PTSD), a severe and debilitating condition. Pharmacological interventions have been proposed for acute symptoms to act as an indicated prevention measure for PTSD development. As many individuals will spontaneously remit, these interventions should balance efficacy and tolerability.

OBJECTIVES

To assess the efficacy and acceptability of early pharmacological interventions for prevention of PTSD in adults experiencing acute traumatic stress symptoms.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trial Register (CCMDCTR), CENTRAL, MEDLINE, Embase and two other databases. We checked the reference lists of all included studies and relevant systematic reviews. The search was last updated on 23 January 2023.

SELECTION CRITERIA

We included randomised controlled trials on adults exposed to any kind of traumatic event and presenting acute traumatic stress symptoms, without restriction on their severity. We considered comparisons of any medication with placebo, or with another medication. We excluded trials that investigated medications as an augmentation to psychotherapy.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures. Using a random-effects model, we analysed dichotomous data as risk ratios (RR) and calculated the number needed to treat for an additional beneficial/harmful outcome (NNTB/NNTH). We analysed continuous data as mean differences (MD) or standardised mean differences (SMD). Our primary outcomes were PTSD severity and dropouts due to adverse events. Secondary outcomes included PTSD rate, functional disability and quality of life.

MAIN RESULTS

We included eight studies that considered four interventions (escitalopram, hydrocortisone, intranasal oxytocin, temazepam) and involved a total of 779 participants. The largest trial contributed 353 participants and the next largest, 120 and 118 participants respectively. The trials enrolled participants admitted to trauma centres or emergency departments. The risk of bias in the included studies was generally low except for attrition rate, which we rated as high-risk. We could meta-analyse data for two comparisons: escitalopram versus placebo (but limited to secondary outcomes) and hydrocortisone versus placebo. One study compared escitalopram to placebo at our primary time point of three months after the traumatic event. There was inconclusive evidence of any difference in terms of PTSD severity (mean difference (MD) on the Clinician-Administered PTSD Scale (CAPS, score range 0 to 136) -11.35, 95% confidence interval (CI) -24.56 to 1.86; 1 study, 23 participants; very low-certainty evidence), dropouts due to adverse events (no participant left the study early due to adverse events; 1 study, 31 participants; very low-certainty evidence) and PTSD rates (RR 0.59, 95% CI 0.03 to 13.08; NNTB 37, 95% CI NNTB 15 to NNTH 1; 1 study, 23 participants; very low-certainty evidence). The study did not assess functional disability or quality of life. Three studies compared hydrocortisone to placebo at our primary time point of three months after the traumatic event. We found inconclusive evidence on whether hydrocortisone was more effective in reducing the severity of PTSD symptoms compared to placebo (MD on CAPS -7.53, 95% CI -25.20 to 10.13; I2 = 85%; 3 studies, 136 participants; very low-certainty evidence) and whether it reduced the risk of developing PTSD (RR 0.47, 95% CI 0.09 to 2.38; NNTB 14, 95% CI NNTB 8 to NNTH 5; I2 = 36%; 3 studies, 136 participants; very low-certainty evidence). Evidence on the risk of dropping out due to adverse events is inconclusive (RR 3.19, 95% CI 0.13 to 75.43; 2 studies, 182 participants; low-certainty evidence) and it is unclear whether hydrocortisone might improve quality of life (MD on the SF-36 (score range 0 to 136, higher is better) 19.70, 95% CI -1.10 to 40.50; 1 study, 43 participants; very low-certainty evidence). No study assessed functional disability.

AUTHORS' CONCLUSIONS

This review provides uncertain evidence regarding the use of escitalopram, hydrocortisone, intranasal oxytocin and temazepam for people with acute stress symptoms. It is therefore unclear whether these pharmacological interventions exert a positive or negative effect in this population. It is important to note that acute traumatic stress symptoms are often limited in time, and that the lack of data prevents the careful assessment of expected benefits against side effects that is therefore required. To yield stronger conclusions regarding both positive and negative outcomes, larger sample sizes are required. A common operational framework of criteria for inclusion and baseline assessment might help in better understanding who, if anyone, benefits from an intervention. As symptom severity alone does not provide the full picture of the impact of exposure to trauma, assessment of quality of life and functional impairment would provide a more comprehensive picture of the effects of the interventions. The assessment and reporting of side effects may facilitate a more comprehensive understanding of tolerability.

Longitudinal method comparison: modeling polygenic risk for post-traumatic stress disorder over time in individuals of African and European ancestry

Cross-sectional data allow the investigation of how genetics influence health at a single time point, but to understand how the genome impacts phenotype development, one must use repeated measures data. Ignoring the dependency inherent in repeated measures can exacerbate false positives and requires the utilization of methods other than general or generalized linear models. Many methods can accommodate longitudinal data, including the commonly used linear mixed model and generalized estimating equation, as well as the less popular fixed-effects model, cluster-robust standard error adjustment, and aggregate regression. We simulated longitudinal data and applied these five methods alongside naïve linear regression, which ignored the dependency and served as a baseline, to compare their power, false positive rate, estimation accuracy, and precision. The results showed that the naïve linear regression and fixed-effects models incurred high false positive rates when analyzing a predictor that is fixed over time, making them unviable for studying time-invariant genetic effects. The linear mixed models maintained low false positive rates and unbiased estimation. The generalized estimating equation was similar to the former in terms of power and estimation, but it had increased false positives when the sample size was low, as did cluster-robust standard error adjustment. Aggregate regression produced biased estimates when predictor effects varied over time. To show how the method choice affects downstream results, we performed longitudinal analyses in an adolescent cohort of African and European ancestry. We examined how developing post-traumatic stress symptoms were predicted by polygenic risk, traumatic events, exposure to sexual abuse, and income using four approaches-linear mixed models, generalized estimating equations, cluster-robust standard error adjustment, and aggregate regression. While the directions of effect were generally consistent, coefficient magnitudes and statistical significance differed across methods. Our in-depth comparison of longitudinal methods showed that linear mixed models and generalized estimating equations were applicable in most scenarios requiring longitudinal modeling, but no approach produced identical results even if fit to the same data. Since result discrepancies can result from methodological choices, it is crucial that researchers determine their model a priori, refrain from testing multiple approaches to obtain favorable results, and utilize as similar as possible methods when seeking to replicate results.

Post-traumatic stress disorder in the Ethiopian population dwelling in war-affected communities: a systematic review and meta-analysis

Background

Post-traumatic stress disorder (PTSD) is a significant mental health concern globally, particularly prevalent in populations exposed to war and conflict. This systematic review and meta-analysis aim to examine the prevalence and factors associated with PTSD among the Ethiopian population residing in war-affected communities.

Methods

The review was reported according to the PRISMA guidelines. Related eligible published articles were searched in electronic online databases such as PubMed, Scopus, Web of Science, MEDLINE/PubMed, Scopus, Embase, Science Direct, Web of Science, Google Scholar, and Google, which reported the prevalence and risk factors of PTSD among people dwelling in the war-affected area until January 2024. The relevant data was extracted using a Microsoft Excel spreadsheet. The meta-analysis was conducted using STATA version 11. The estimated pooled prevalence and risk factors were estimated using a random effect model. The potential risk of publication bias was checked using a funnel plot and Egger's statistical test.

Results

A total of nine published studies with 6107 participants were analyzed in this meta-analysis. The estimated pooled prevalence of PTSD among people living in war-affected areas was 48.4%, with a 95% CI (37.1, 59.8). This study found a higher prevalence of PTSD among women than men. Being female (OR= 2.2, 95% CI: 1.2, 4.3), witnessing a murder of a loved one (OR= 3.0, 95% CI: 1.2, 7.5), depression symptoms (OR= 2.8, 95% CI: 1.4, 5.6), and anxiety symptoms (OR= 3.4, 95% CI: 1.4, 8.0), a close family member killed or seriously injured (OR= 3.1, 95% CI: 1.2, 7.7), a moderate and high perceived threat to life (OR= 3.4, 95% CI: 1.3, 9.1), and poor social support (OR= 4.4, 95% CI: 1.1, 18.7) were associated with post-traumatic stress disorder.

Conclusion

The result of this study shows the high prevalence rate of PTSD in people living in war-affected areas. disparities in PTSD prevalence, with women being at higher risk, and identified risk factors were witnessing the murder of a loved one, experiencing depression and anxiety, and perceived threat to life. Addressing PTSD in war-affected communities requires comprehensive interventions that consider both individual and contextual factors.

The prevalence and determinants of PTSD, anxiety, and depression in Ukrainian civilian physicians and paramedics in wartime-An observational cross-sectional study six months after outbreak

Russia's invasion of Ukraine is the largest European land offensive since World War II. Individuals affected by conflicts such as war are at an increased risk of mental disorders, which result from frequent exposure to traumatic events and the breakdown of supportive social networks. The aim of the study was to assess the prevalence and determinants of PTSD, anxiety, and depression in Ukrainian civilian physicians and paramedics six months after the Russian invasion of Ukraine. A cross-sectional study was conducted using validated questionnaires: The Life Events Checklist, PTSD Checklist for DSM-5, The International Trauma Questionnaire (ICD-11), The Generalized Anxiety Disorder-7, The Patient Health Questionnaire-9, The World Health Organization Disability Assessment Schedule 2.0. The study showed that 61.1 % of participants indicated combat or exposure to a war zone as the most bothersome event in their experience. Physicians and paramedics did not differ in the prevalence of PTSD according to the DSM-5 diagnostic rule and of depression (criteria met by 14.5 % and 9 % of participants, respectively). However, more physicians than paramedics met the criteria of PTSD according to the ICD-11 diagnostic rule (5.1 % vs. 1.2 %) and of anxiety (16.5 % vs. 10.0 %). The risk factors for the mental health problems included personal combat experience, total trauma exposure, parenthood, and economic situation. Despite the differences found in the prevalence of PTSD depending on the criteria used, the severity of mental problems and disability in this group is significant. It is advisable to monitor the mental state and need for help among Ukrainian civilian medical personnel.

A pilot clinical trial of the Screening and Tool for Awareness and Relief of Trauma for survivors of gun violence

BACKGROUND

Survivors of gun violence have significant sequelae including reinjury with a firearm and mental health disorders that often go undiagnosed and untreated. The Screening and Tool for Awareness and Relief of Trauma (START) is a targeted behavioral mental health intervention developed for patients who come from communities of color with sustained and persistent trauma.

METHODS

In this pilot study, we evaluate the feasibility of completing a randomized controlled trial to test the START intervention. Using a mixed methods study design, we used both quantitative and qualitative data collection to assess the START intervention and the feasibility of completing a randomized controlled trial. The purpose of this study was to estimate important study parameters that would enable a future randomized controlled trial.

RESULTS

We were able to make conclusions about several crucial domains of a behavioral intervention trial: (1) recruitment and retention-we had a high follow-up rate, but our recruitment was low (34% of eligible participants); (2) acceptability of the intervention-the addition of audiovisual resources would make the tools more accessible; (3) feasibility of the control-more appropriate for a stepped wedge cluster randomized controlled trial design; (4) intervention fidelity-there was an 81% concordance rate between the fidelity survey results and the audio recordings; (5) approximate effect size-there was a 0.4-point decrease in the PTSD Checklist-Civilian Version in the control compared with a 10.7-point decrease in the treatment group for the first month.

CONCLUSION

While it was feasible to conduct a randomized controlled trial, our findings suggest that a stepped wedge cluster randomized controlled trial design may be the most successful trial design for the START intervention. In addition, the inclusion of a "credible messenger" to recruit participants into the study and the development of audiovisual resources for START would improve recruitment and effectiveness.

Effects of Antidepressants on Sleep in Post-traumatic Stress Disorder: An Overview of Reviews

Antidepressants are a commonly used, easily accessible, and overall safe treatment option for post-traumatic stress disorder (PTSD). The present review aims to evaluate the efficacy and safety of antidepressants in treating sleep disturbances in patients with PTSD. PubMed and the Cochrane Library were searched (July 2022) for systematic reviews and meta-analyses on the treatment of PTSD. Moreover, PubMed and ClinicalTrials.gov were searched for individual trials investigating the antidepressant treatment of PTSD (up to September 2022), and reference lists of all possibly relevant identified studies were screened. Sleep-related outcomes, i.e., total sleep time, sleep quality, dreams/ nightmares, insomnia, and somnolence, were extracted independently by at least two reviewers. Metaanalytic evaluations were performed wherever possible. 39 randomised controlled trials (RCTs) were identified; data from pooled analyses, reviews, and observational studies were used for antidepressants with a weak evidence base or when their findings were deemed important. Overall, scarce data exist on the effects of antidepressants on sleep outcomes among patients with PTSD. Some evidence may support the use of amitriptyline, nefazodone, paroxetine, and sertraline for improving sleep in patients with PTSD. Τhere was a meta-analytical trend indicating improvement of nightmares with fluoxetine, less insomnia with amitriptyline and more with brofaromine, as well as more somnolence with paroxetine vs. placebo, respectively. However, data from more than 1 RCT with a considerable number of patients were only available for paroxetine. Evidence is insufficient to draw safe conclusions. More and better-designed RCTs, with consistent reporting of sleep-related outcomes, are needed.

Risk factors for postpartum posttraumatic stress disorder after emergency admission

BACKGROUND

Postpartum posttraumatic stress disorder (PTSD) can occur in women who give birth after emergency admission. The identification of risk factors for this condition is crucial for developing effective preventive measures. This retrospective study aimed to explore the incidence and risk factors for postpartum PTSD in women who give birth after emergency admission.

METHODS

Medical records of women who gave birth after emergency admission were collected between March 2021 and April 2023. The patients' general conditions and perinatal clinical indicators were recorded. The puerperae were divided into PTSD group and control group based on symptom occurrence at six weeks postpartum. Multivariate logistic regression analysis was performed to identify risk factors.

RESULTS

A total of 276 puerperae were included, with a PTSD incidence of 20.3% at six weeks postpartum. Multivariate logistic regression analysis identified emergency cesarean section (odds ratio [OR]=2.102; 95% confidence interval [CI]: 1.114-3.966, P=0.022), admission to the emergency department after midnight (12:00 AM) (OR=2.245; 95%CI: 1.170-4.305, P<0.001), and cervical dilation (OR=3.203; 95%CI: 1.670-6.141, P=0.039) as independent risk factors for postpartum PTSD. Analgesia pump use (OR= 0.500; 95%CI: 0.259-0.966, P=0.015) was found to be a protective factor against postpartum PTSD.

CONCLUSION

Emergency cesarean section, admission to the emergency department after midnight, and cervical dilation were identified as independent risk factors for postpartum PTSD, while analgesic pump use was a protective factor. These findings provide insights for developing more effective preventive measures for women who give birth after emergency admission.

Contemporary issues in the management of dental trauma

Contemporary diagnosis and management of traumatic dental injuries requires a multifaceted understanding of the pathological and psychological impact over a patient's lifetime. The legacy of dental trauma injuries can have repercussions for the dentition and supporting tissues, requiring complicated multidisciplinary clinical input. Foresight is required to ensure optimal aesthetic and functional outcomes. Mitigating risks and maximising benefits in patients presenting with polytrauma can be challenging, but if optimally managed at the acute presentation, the long-term burden to the patient and the clinician is reduced. This paper aims to discuss the contemporary clinical dilemmas, challenges and controversies related to the management of dental trauma.

The impact of patient death experiences early in training on resident physicians: a qualitative study

BACKGROUND

Patient death is an inevitability during medical training, with subsequent psychologic distress, decreased empathy and worse learning outcomes. We aimed to explore resident experiences with patient death early in training, including the immediate and delayed impacts of these experiences, preparedness of trainees for these events and coping strategies used, potentially identifying gaps and opportunities to further support trainees during difficult or traumatic events.

METHODS

We performed a qualitative study using phenomenology methodology to understand trainees' personal experiences with patient death. Resident physicians who had completed an internal medicine rotation at McMaster University, Hamilton, Ontario, were invited to participate from December 2020 to April 2021. Semistructured interviews were conducted to understand circumstances, emotional responses, support, coping mechanisms and preparedness regarding the patient death experience. Interviews were transcribed and coded to identify emerging themes with the use of thematic and interpretive analysis.

RESULTS

Eighteen participants were interviewed. On average, the interviews were 40 minutes in length. The participants' mean age was 27 years. The majority of trainees (10 [56%]) were in their first year of residency, with 5 (28%) from family medicine and 4 (22%) from internal medicine. Most participants (13 [72%]) had experienced their first patient death during medical school. Three themes were identified: patient death circumstances, immediate and delayed emotional impact, and preparedness and coping mechanisms. Unexpected death, pronouncing death, cardiopulmonary resuscitation and communicating with families were common challenges. Feelings of guilt, helplessness and grief followed the events. Feeling underprepared contributed to emotional consequences, including difficulties sleeping, intrusive thoughts and emotional distancing; however, these experiences were consistently normalized by participants.

INTERPRETATION

Patient death during medical training can be traumatic for trainees and may perpetuate loss of empathy, changes to practice and residual emotional effects. Educational initiatives to prepare trainees for patient death and teach adaptive coping strategies may help mitigate psychologic trauma and loss of empathy; further research is required to explore these strategies.

Posttraumatic stress disorder in a war-affected area of Northeast Ethiopia: a cross-sectional study

BACKGROUND

Post-Traumatic Stress Disorder (PTSD) is a chronic condition that affects a significant proportion of war survivors following war and conflict. If PTSD is not managed, it can lead to decreased quality of life and impairments in daily functioning and lead to death. This study aimed to assess the prevalence of post-traumatic stress disorder and its associated factors among residents in a war-affected area, Dessie Town, Northeast Ethiopia.

METHODS

A community-based cross-sectional study was conducted among adult residents in the war-affected area, Dessie Town. A total of 615 individuals were selected by a systematic random sampling method. PTSD was assessed using the Post-Traumatic Stress Disorder Checklist, Civilian Version. Multivariable logistic regressions were used to measure the associated factors. Associations between variables were described using odds ratios, 95% confidence intervals, and a p-value less than 0.05.

RESULTS

The prevalence of PTSD was 34.5% (95% CI: 31-38). Female sex (AOR: 1.82; CI: 1.18-2.82), divorced or widowed (AOR: 2.12, CI: 1.23-3.66), having only primary schooling (AOR: 2.17; CI: 1.25-3.78), depression (AOR: 2.03; CI: 1.34-3.08), experienced ill health without medical care during the wartime (AOR: 2.97; CI: 1.43-6.16), forced separation from family (AOR: 1.90; CI: 1.16-3.12), and experienced stressful life events (AOR: 1.60; CI: 1.06-2.42) were significantly associated with PTSD.

CONCLUSION

A significant rate of PTSD was found among residents of the war-affected area, Dessie Town. One in three people was experiencing PTSD. As a result, post-war mental health early screening and intervention is a priority, particularly for females, those who are separated or divorced, and those who have experienced stressful life events due to the war.

A Systematic Review of Interventions for Prevention and Treatment of Post-Traumatic Stress Disorder Following Childbirth

Objective

Postpartum women can develop post-traumatic stress disorder (PTSD) in response to complicated, traumatic childbirth; prevalence of these events remains high in the U.S. Currently, there is no recommended treatment approach in routine peripartum care for preventing maternal childbirth-related PTSD (CB-PTSD) and lessening its severity. Here, we provide a systematic review of available clinical trials testing interventions for the prevention and indication of CB-PTSD.

Data Sources

We conducted a systematic review of PsycInfo, PsycArticles, PubMed (MEDLINE), ClinicalTrials.gov, CINAHL, ProQuest, Sociological Abstracts, Google Scholar, Embase, Web of Science, ScienceDirect, and Scopus through December 2022 to identify clinical trials involving CB-PTSD prevention and treatment.

Study Eligibility Criteria

Trials were included if they were interventional, evaluated CB-PTSD preventive strategies or treatments, and reported outcomes assessing CB-PTSD symptoms. Duplicate studies, case reports, protocols, active clinical trials, and studies of CB-PTSD following stillbirth were excluded.

Study Appraisal and Synthesis Methods

Two independent coders evaluated trials using a modified Downs and Black methodological quality assessment checklist. Sample characteristics and related intervention information were extracted via an Excel-based form.

Results

A total of 33 studies, including 25 randomized controlled trials (RCTs) and 8 non-RCTs, were included. Trial quality ranged from Poor to Excellent. Trials tested psychological therapies most often delivered as secondary prevention against CB-PTSD onset (n=21); some examined primary (n=3) and tertiary (n=9) therapies. Positive treatment effects were found for early interventions employing conventional trauma-focused therapies, psychological counseling, and mother-infant dyadic focused strategies. Therapies' utility to aid women with severe acute traumatic stress symptoms or reduce incidence of CB-PTSD diagnosis is unclear, as is whether they are effective as tertiary intervention. Educational birth plan-focused interventions during pregnancy may improve maternal health outcomes, but studies remain scarce.

Conclusions

An array of early psychological therapies delivered in response to traumatic childbirth, rather than universally, in the first postpartum days and weeks, may potentially buffer CB-PTSD development. Rather than one treatment being suitable for all, effective therapy should consider individual-specific factors. As additional RCTs generate critical information and guide recommendations for first-line preventive treatments for CB-PTSD, the psychiatric consequences associated with traumatic childbirth could be lessened.

Identifying genetic loci that are associated with changes in gene expression in PTSD in a South African cohort

The molecular mechanisms underlying posttraumatic stress disorder (PTSD) are yet to be fully elucidated, especially in underrepresented population groups. Expression quantitative trait loci (eQTLs) are DNA sequence variants that influence gene expression, in a local (cis-) or distal (trans-) manner, and subsequently impact cellular, tissue, and system physiology. This study aims to identify genetic loci associated with gene expression changes in a South African PTSD cohort. Genome-wide genotype and RNA-sequencing data were obtained from 32 trauma-exposed controls and 35 PTSD cases of mixed-ancestry, as part of the SHARED ROOTS project. The first approach utilised 108 937 single-nucleotide polymorphisms (SNPs) (MAF > 10%) and 11 312 genes with Matrix eQTL to map potential eQTLs, while controlling for covariates as appropriate. The second analysis was focused on 5638 SNPs related to a previously calculated PTSD polygenic risk score for this cohort. SNP-gene pairs were considered eQTLs if they surpassed Bonferroni correction and had a false discovery rate <0.05. We did not identify eQTLs that significantly influenced gene expression in a PTSD-dependent manner. However, several known cis-eQTLs, independent of PTSD diagnosis, were observed. rs8521 (C > T) was associated with TAGLN and SIDT2 expression, and rs11085906 (C > T) was associated with ZNF333 expression. This exploratory study provides insight into the molecular mechanisms associated with PTSD in a non-European, admixed sample population. This study was limited by the cross-sectional design and insufficient statistical power. Overall, this study should encourage further multi-omics approaches towards investigating PTSD in diverse populations.

Mind-body exercise interventions for prevention of post-traumatic stress disorder in trauma-exposed populations: a systematic review and meta-analysis

OBJECTIVE

Mind-body exercise (MBE) interventions, such as yoga, are increasingly recognised as an adjunct treatment for trauma-related mental disorders but less is known about their efficacy as a preventative intervention. We aimed to systematically review if, and what type of, MBE interventions are effective at preventing the development of post-traumatic stress disorder (PTSD) or acute stress disorder (ASD) in trauma-exposed populations.

DESIGN

Systematic review and meta-analysis.

METHODS

A systematic search of MEDLINE, PsycINFO, EMBASE and CENTRAL databases was conducted to identify controlled trials of MBE interventions aimed at preventing the development of PTSD or ASD in high-risk populations. Risk of bias was assessed using the revised Cochrane risk-of-bias and ROBINS-I tools. Pooled effect sizes using Hedges' g and 95% CIs were calculated using random effects modelling for the main meta-analysis and planned subgroup and sensitivity analyses.

RESULTS

Six studies (N analysed=399) were included in the final meta-analysis. Overall, there was a small effect for MBE interventions in preventing the development of PTSD (g=-0.25, 95% CI -0.56 to 0.06) among those with previous or ongoing exposure to trauma. Although a prespecified subgroup analyses comparing the different types of MBE intervention were conducted, meaningful conclusions could not be drawn due to the small number of studies. None of the included studies assessed ASD symptoms.

CONCLUSION

Limited evidence was found for MBE interventions in reducing PTSD symptomology in the short term. Findings must be interpreted with caution due to the small number of studies and possible publication bias.

Postintensive Care Syndrome: Feasibly Bridging Care at a Tertiary Trauma Center

BACKGROUND

Advancements in critical care management have improved mortality rates of trauma patients; however, research has identified physical and psychological impairments that remain with patients for an extended time. Cognitive impairments, anxiety, stress, depression, and weakness in the postintensive care phase are an impetus for trauma centers to examine their ability to improve patient outcomes.

OBJECTIVE

This article describes one center's efforts to intervene to address postintensive care syndrome in trauma patients.

METHODS

This article describes implementing aspects of the Society of Critical Care Medicine's liberation bundle to address postintensive care syndrome in trauma patients.

RESULTS

The implementation of the liberation bundle initiatives was successful and well received by trauma staff, patients, and families. It requires strong multidisciplinary commitment and adequate staffing. Continued focus and retraining are requirements in the face of staff turnover and shortages, which are real-world barriers.

CONCLUSIONS

Implementation of the liberation bundle was feasible. Although the initiatives were positively received by trauma patients and their families, we identified a gap in the availability of long-term outpatient services for trauma patients after discharge from the hospital.

Post-traumatic stress disorder and the risk of violent crime conviction in Sweden: a nationwide, register-based cohort study

BACKGROUND

Post-traumatic stress disorder (PTSD) has been linked to violent crime in veteran populations. However, whether there is a link between PTSD and violent crime in the general population is not known. This study aimed to investigate the hypothesised association between PTSD and violent crime in the Swedish general population and to investigate the extent to which familial factors might explain this association using unaffected sibling control individuals.

METHODS

This nationwide, register-based cohort study assessed individuals born in Sweden in 1958-93 for eligibility for inclusion. Individuals who died or emigrated before their 15th birthday, were adopted, were twins, or whose biological parents could not be identified were excluded. Participants were identified and included from the National Patient Register (1973-2013), the Multi-Generation Register (1932-2013), the Total Population Register (1947-2013), and the National Crime Register (1973-2013). Participants with PTSD were matched (1:10) with randomly selected control individuals from the population without PTSD by birth year, sex, and county of residence in the year of PTSD diagnosis for the matched individual. Each participant was followed up from the date of matching (ie, the index person's first PTSD diagnosis) until violent crime conviction or until being censored at emigration, death, or Dec 31, 2013, whichever occurred first. Stratified Cox regressions were used to estimate the hazard ratio of time to violent crime conviction ascertained from national registers in individuals with PTSD compared with control individuals. To account for familial confounding, sibling analyses were conducted, comparing the risk of violent crime in a subsample of individuals with PTSD with their unaffected full biological siblings.

FINDINGS

Of 3 890 765 eligible individuals, 13 119 had a PTSD diagnosis (9856 [75·1%] of whom were female and 3263 [24·9%] of whom were male), were matched with 131 190 individuals who did not, and were included in the matched cohort. 9114 individuals with PTSD and 14 613 full biological siblings without PTSD were also included in the sibling cohort. In the sibling cohort, 6956 (76·3%) of 9114 participants were female and 2158 (23·7%) were male. Cumulative incidence of violent crime convictions after 5 years was 5·0% (95% CI 4·6-5·5) in individuals diagnosed with PTSD versus 0·7% (0·6-0·7) in individuals without PTSD. At the end of follow-up (median follow-up time 4·2 years, IQR 2·0-7·6), cumulative incidence was 13·5% (11·3-16·6) versus 2·3% (1·9-2·6). Individuals with PTSD had a significantly higher risk of violent crime than the matched control population in the fully-adjusted model (hazard ratio [HR] 6·4, 95% CI 5·7-7·2). In the sibling cohort, the risk of violent crime was also significantly higher in the siblings with PTSD (3·2, 2·6-4·0).

INTERPRETATION

PTSD was associated with increased risk of violent crime conviction, even after controlling for familial effects shared by siblings and in the absence of SUD or a history of violent crime. Although our results might not be generalisable to less severe or undetected PTSD, our study could inform interventions that aim to reduce violent crime in this vulnerable population.

Effect of Dexmedetomidine on Posttraumatic Stress Disorder in Patients Undergoing Emergency Trauma Surgery: A Randomized Clinical Trial

Importance

Posttraumatic stress disorder (PTSD) is common in people who have experienced trauma, especially those hospitalized for surgery. Dexmedetomidine may reduce or reverse the early consolidation and formation of conditioned fear memory and prevent the occurrence of postoperative PTSD.

Objective

To evaluate the effects of intraoperative and postoperative low-dose intravenous pumping dexmedetomidine on PTSD among patients with trauma undergoing emergency surgery.

Design, Setting, and Participants

This double-blind, randomized clinical trial was conducted from January 22 to October 20, 2022, with follow-up 1 month postoperatively, in patients with trauma undergoing emergency surgery at 4 hospital centers in Jiangsu Province, China. A total of 477 participants were screened. The observers were blinded to patient groupings, particularly for subjective measurements.

Interventions

Dexmedetomidine or placebo (normal saline) was administered at a maintenance dose of 0.1 μg/kg hourly from the start of anesthesia until the end of surgery and at the same rate after surgery from 9 pm to 7 am on days 1 to 3.

Main Outcomes and Measures

The primary outcome was the difference in the incidence of PTSD 1 month after surgery in the 2 groups. This outcome was assessed with the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (CAPS-5). The secondary outcomes were the pain score within 48 hours and 1 month postoperatively; incidence of postoperative delirium, nausea, and pruritus; subjective sleep quality; anxiety; and occurrence of adverse events.

Results

A total of 310 patients (154 in the normal saline group and 156 in the dexmedetomidine group) were included in the modified intention-to-treat analysis (mean [SD] age, 40.2 [10.3] years; 179 men [57.7%]). The incidence of PTSD was significantly lower in the dexmedetomidine group than in the control group 1 month postoperatively (14.1% vs 24.0%; P = .03). The participants in the dexmedetomidine group had a significantly lower CAPS-5 score than those in the control group (17.3 [5.3] vs 18.9 [6.6]; mean difference, 1.65; 95% CI, 0.31-2.99; P = .02). After adjusting for potential confounders, the patients in the dexmedetomidine group were less likely to develop PTSD than those in the control group 1 month postoperatively (adjusted odds ratio, 0.51; 95% CI, 0.27-0.94; P = .03).

Conclusions and Relevance

In this randomized clinical trial, the administration of intraoperative and postoperative dexmedetomidine reduced the incidence of PTSD among patients with trauma. The findings of this trial support the use of dexmedetomidine in emergency trauma surgery.

Dissecting the causal association between inflammation and post-traumatic stress disorder: A bidirectional Mendelian randomization study

BACKGROUND

Accumulating evidence showed a bidirectional association between post-traumatic stress disorder and inflammation. However, whether the association is causal remains unclear. We aimed to evaluate the causal relationships between inflammatory cytokines and post-traumatic stress disorder using two-sample bi-directional Mendelian randomization analysis.

METHODS

Single nucleotide polymorphism from genome-wide association studies of inflammatory cytokines, C-reactive protein, and post-traumatic stress disorder (23,212 patients and 151,447 controls) was selected as instrumental variables. The causal associations were estimated by inverse variance weighting with sensitivity analyses using weighted median, MR-Egger, and MR-PRESSO methods.

RESULTS

We observed suggestive associations of genetically predicted interleukin-17 (IL-17) and RANTES with post-traumatic stress disorder. One standard deviation (SD) increase in genetically predicted level of IL-17 lowered the risk of post-traumatic stress disorder with an odds ratio (OR) of 0.902 (95 % CI = 0.828, 0.984, P = 0.02). One SD higher genetically predicted RANTES (CCL5) concentration increased post-traumatic stress disorder risk (OR = 1.067, 95 % CI = 1.005, 1.133, P = 0.032). However, we found no evidence of causal associations of post-traumatic stress disorder with the selected inflammatory cytokines and biomarkers. We observed no evidence supporting the presence of pleiotropy. The results of sensitivity analyses demonstrated the same directions and similar effect sizes as the primary findings.

LIMITATIONS

Potential pleiotropy, possible weak instruments, and low statistical power limited our findings.

CONCLUSION

Inflammation was suggestively causally associated with the risk of post-traumatic stress disorder, and inflammatory cytokines had no downstream effect on post-traumatic stress disorder. Further studies are needed to explain the mechanisms of systemic inflammation and neuroinflammation in post-traumatic stress disorder.

Epigenetic Effects of Social Stress and Epigenetic Inheritance

Social events that cause stress can cause epigenetic changes on living things. The study of the effects of social events experienced by an individual on epigenetic marks on the genome has created the field of social epigenetics. Social epigenetics examines the effects of psychosocial stress factors such as poverty, war trauma and childhood abuse on epigenetic mechanisms. Epigenetic mechanisms alter chemical markers in the genome structure without changing the DNA sequence. Among these mechanisms, DNA methylation in particular may have different phenotypic effects in response to stressors that may occur in the psychosocial environment. Post-traumatic stress disorder is one of the most significant proofs of the effects of epigenetic expressions altered due to traumatic events on the phenotype. The field of epigenetic inheritance has shown that epigenetic changes triggered by environmental influences can, in some cases, be transmitted through generations. This field provides a better understanding of the basis of many psychological disorders. This review provides an overview of social epigenetics, PTSD, and epigenetic inheritance.

Ketamine as a therapeutic agent in major depressive disorder and posttraumatic stress disorder: Potential medicinal and deleterious effects

Major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are the most common causes of emotional distress that impair an individual's quality of life. MDD is a chronic mental illness that affects 300 million people across the world. Clinical manifestations of MDD include fatigue, loss of interest in routine tasks, psychomotor agitation, impaired ability to focus, suicidal ideation, hypersomnolence, altered psychosocial functioning, and appetite loss. Individuals with depression also demonstrate a reduced behavioral response while experiencing pleasure, a symptom known as anhedonia. Like MDD, PTSD is a prevalent and debilitating psychiatric disorder resulting from a traumatic incident such as sexual assault, war, severe accident, or natural disaster. Symptoms such as recalling event phases, hypervigilance, irritability, and anhedonia are common in PTSD. Both MDD and PTSD pose enormous socioeconomic burdens across the globe. The search for effective treatment with minimal side effects is still ongoing. Ketamine is known for its anesthetic and analgesic properties. Psychedelic and psychotropic effects of ketamine have been found on the nervous system, which highlights its toxicity. In this article, the effectiveness of ketamine as a potential therapeutic for PTSD and MDD along with its mechanisms of action, clinical trials, and possible side effects have been discussed.

Glucocorticoid-based pharmacotherapies preventing PTSD

Posttraumatic stress disorder (PTSD) is a highly disabling psychiatric condition that may arise after exposure to acute and severe trauma. It is a highly prevalent mental disorder worldwide, and the current treatment options for these patients remain limited due to low effectiveness. The time window right after traumatic events provides clinicians with a unique opportunity for preventive interventions against potential deleterious alterations in brain function that lead to PTSD. Some studies pointed out that PTSD patients present an abnormal function of the hypothalamic-pituitary-adrenal axis that may contribute to a vulnerability toward PTSD. Moreover, glucocorticoids have arisen as a promising option for preventing the disorder's development when administered in the aftermath of trauma. The present work compiles the recent findings of glucocorticoid administration for the prevention of a PTSD phenotype, from human studies to animal models of PTSD. Overall, glucocorticoid-based therapies for preventing PTSD demonstrated moderate evidence in terms of efficacy in both clinical and preclinical studies. Although clinical studies point out that glucocorticoids may not be effective for all patients' subpopulations, those with adequate traits might greatly benefit from them. Preclinical studies provide precise insight into the mechanisms mediating this preventive effect, showing glucocorticoid-based prevention to reduce long-lasting behavioral and neurobiological abnormalities caused by traumatic stress. However, further research is needed to delineate the precise mechanisms and the extent to which these interventions can translate into lower PTSD rates and morbidity. This article is part of the Special Issue on 'Fear, Anxiety and PTSD'.

Cognitive Behavior Therapy by Nurses in Reducing Symptoms of Post-Traumatic Stress Disorder on Children as Victims of Violence: A Scoping Review

Violence against children can cause psychological problems such as post-traumatic syndrome disorder (PTSD). The negative impact of violence on children is psychological and physical problems and risk of suicide. Nurses have a role to provide comprehensive nursing care such as cognitive behavior therapy for reducing PTSD symptoms. The purpose of this study was to describe the methods of cognitive behavior therapy to reduce symptoms of PTSD in children who are victims of violence. This study used the scoping review method. The databases use for the literature review in this study were CINAHL, PubMed, and Scopus. The keywords used in English were "cognitive behavioral therapy OR CBT" AND "violence OR abuse" AND "post-traumatic stress disorder OR PTSD" AND "child OR children". The inclusion criteria were full text, randomized control trial or quasi-experimental research design, English language, the sample was children, and the publication period was for the last 10 years (2013-2022). We found 10 articles discussing CBT intervention on children who experienced victim abuse to reduce symptoms of PTSD. Most of the articles in this study used randomized control trial design. Several samples in this study are from the USA. The total sample was 47-320 respondents. This study showed three methods of CBT, namely psychoeducation, self-management, and coping strategies. CBT interventions can be carried out face-to-face or online. The activities carried out by the participants were relaxing, participating in training, counseling, problem-solving discussions, and therapy to improve sleep quality. Cognitive behavioral therapy is an intervention that can be carried out to reduce the traumatic impact on child victims of violence by taking into account the characteristics and development of the children.

Evaluation of a critical incident management system on mental health in lifeguard organisations: a retrospective study

Background

Lifeguards may face many life-threatening situations during their careers and may be at increased risk of post-traumatic stress disorder (PTSD). Minimal evidence concerning critical incident management systems in lifeguard organisations exists.

Objectives

To develop, implement and evaluate an operational system for critical incident management in lifeguard organisations.

Methods

This retrospective study included data on occupational injury reports from 2013 to 2022 in TrygFonden Surf Lifesaving Denmark. All active lifeguards were invited to evaluate the system and the individual steps using an online questionnaire with three questions rated on a 5-point Likert scale. Primary outcome was a change in the frequency of psychological injury reports after system implementation in 2020. The secondary outcome was the lifeguards' satisfaction with the system.

Results

After implementation, the average annual number of psychological injury reports increased 6.5-fold from 2 (2013-2019) to 13 (2020-2022), without changes to the number of critical incidents attended by the lifeguards. Sixty-six (33.8%) active lifeguards answered the questionnaire and agreed that follow-up after critical incidents was very important (mean score 4.7/5). Satisfaction with steps 1-2 and 3 of critical incident management among involved lifeguards was high (mean score 4.4/5 and 4.6/5, respectively). The system included an operational workflow diagram and incident report template presented in this study.

Conclusions

The operational system for critical incident management may improve early recognition of symptoms for the prevention of PTSD. It may be used as a screening and decision tool for referral to a mental health professional.

Effects of transcranial direct current stimulation (tDCS) in "Kiss nightclub fire" patients with post-traumatic stress disorder (PTSD): A phase II clinical trial

Objective

Considered the second biggest tragedy with fatal victims caused by fire, the Kiss nightclub fire tragedy that occurred in the interior of southern Brazil brought several problems to survivors. It is reported that 30-40% of victims of disasters can develop post-traumatic stress disorder. Application of repetitive transcranial magnetic stimulation has shown promising results in the treatment of post-traumatic stress disorder. Transcranial direct current stimulation similar to repetitive transcranial magnetic stimulation, a neuromodulation technique, has shown promise in treatment of neuropsychiatric disorders.

Method

A clinical trial was conducted from March 2015 to July 2016 in "KISS nightclub fire" disaster patients diagnosed with post-traumatic stress disorder without complete remission of symptoms, over 18 years, and who maintained pharmacological treatment. Treatment was given using electrodes as cathode (right dorsolateral prefrontal cortex) and anode (contralateral deltoid muscle); a current of 2 mA was used for 25 cm² area (0.08 mA/cm² current density); 30 min once a day for 10 days continuously. Patients assessed pre- and post-intervention, 30 days' and 90 days' post-intervention. Post-Traumatic Stress Disorder Checklist, Civilian version, Montreal Cognitive Assessment, and Hamilton Depression and Anxiety Rating Scale were used.

Results

One hundred forty-five subjects were screened and eight analyzed; 87.5% were female; 30.88 ± 7.74 years were of mean age. Post-intervention results: no cognitive impairment (Montreal Cognitive Assessment), 60% reduction in Hamilton Depression Rating Scale (moderate depression turns normal) (p < 0.001), 54.39% Hamilton Anxiety Rating Scale reduction (moderate-to-severe symptoms turn into mild symptoms) (p < 0.001), and 20% Post-Traumatic Stress Disorder Checklist, Civilian version scale decrease (high severity post-traumatic stress disorder symptoms turn moderate to moderately high severity) (p < 0.001). Post-traumatic stress disorder symptoms improvement was maintained 30-days post-intervention (Post-Traumatic Stress Disorder Checklist, Civilian version, p = 0.025) and improvement in symptoms of depression (Hamilton Depression Rating Scale, p = 0.006) and anxiety (Hamilton Anxiety Rating Scale, p = 0.028) in 90 days post-intervention.

Conclusion

Despite decrease over time, improvement in post-traumatic stress disorder, depression and anxiety symptoms was maintained throughout the first month after treatment. Transcranial direct current stimulation adjuvant can be an alternative treatment to refractory post-traumatic stress disorder, either as monotherapy or as treatment enhancement strategy. They can also be an option for patients who do not want or do not tolerate pharmacological management.

Navigating Trauma Patients and Families Through Unfamiliar Territory

BACKGROUND

Trauma teams work diligently to manage the complex medical needs of trauma patients. In addition to medical care, there is also a need to assist patients and their families as they navigate the emotional and physical journey of trauma. The role of trauma nurse navigator was developed to address these holistic needs.

OBJECTIVE

This article aims to describe the implementation of a trauma nurse navigator role.

METHODS

This article describes the development and implementation of a trauma nurse navigator role at a Level II trauma center in 2018. The trauma nurse navigator serves as a patient resource and utilizes creative problem solving to optimize care. The trauma nurse navigator also serves on the multidisciplinary team, working with providers, nursing staff, rehabilitation staff, and case management to provide seamless care to trauma patients.

RESULTS

Implementation of the trauma nurse navigator role was well received by patients, families, and the multidisciplinary trauma team. The trauma nurse navigator role expanded the psychosocial support of trauma patients and increased patient satisfaction.

CONCLUSION

Although other specialties have seen the benefits of including a patient navigator on the team, this is a potential for trauma centers as they strive to provide high-quality patient care.

Predicting PTSD symptoms in firefighters using a fear-potentiated startle paradigm and machine learning

This study develops a fear-potentiated startle paradigm (FPS) and a machine learning approach to accurately predict PTSD symptoms using electrogram data. A three-phase fear-potentiated startle paradigm was designed to assess the conditioning, generalization, and extinction of fear. Electrooculogram and electrocardiogram signals were collected during the FPS. A total of 1107 Chinese firefighters participated in the study. The Chinese version PCL-C was administered to all subjects. A cutoff of 38 or higher is used to indicate PTSD symptoms. Electrogram features were extracted and selected to build a machine learning model to classify individuals. The machine learning model was 5-fold cross validated. The importance of the selected features was calculated. Classification performance metrics were evaluated for the machine learning model. The machine learning model can identify firefighters with a PCL-C score of 38 or above with sensitivity and specificity both above 0.85 when 5-fold cross validated on a 1107-person sample. The area under the receiver operating characteristic curve of the model is 0.93. Features related to fear generalization are found to be the most important. The proposed fear-potentiated startle paradigm and machine learning approach can accurately predict PTSD symptoms in Chinese firefighters, which can improve the screening and diagnosis of PTSD.

Civilian Military Security Coordinators Coping with Frequent Traumatic Events: Spirituality, Community Resilience, and Emotional Distress

Civilian military security coordinators are a unique kind of first responders. They live in communities that are close to the border and are responsible for the security of their community in routine and emergency situations until the arrival of the army or the police. Their role puts them at an elevated risk of experiencing emotional distress and developing PTSD. The present study, which was conducted in Israel following terror incidents over the year 2018, aimed to examine the relationships between spirituality and perceived community resilience, on the one hand, and PTSD symptoms and stress, on the other, among civilian military security coordinators. One hundred and thirteen (n = 113) civilian military security coordinators living up to 12.4 miles from the border who are routinely exposed to terror and other traumatic events completed demographic, spirituality, community resilience, PTSD, and stress questionnaires. Structural-equation-model analyses showed that spirituality was negatively associated with PTSD symptoms and stress. However, perceived community resilience was not associated with PTSD symptoms or stress. In addition, age was negatively associated with PTSD symptoms and stress. Financial situation was also negatively associated with PTSD symptoms and stress and incidence of exposure to terror and security threats was associated only with PTSD symptoms. Theoretical and practical implications are discussed.

Breaking Silos to Address Medical Trauma: The Need for Integration of Trauma and Health Psychology Training

Posttraumatic Stress Disorder (PTSD) following a traumatic injury is a significant public health concern impacting approximately a third of traumatically injured patients. In 2018, the American College of Surgeons (ACS) Committee on Trauma recommended implementation of PTSD screening and brief intervention in level 1 trauma centers to meet the mental health needs of this underserved population. In March 2022, ACS revised its standards to include a requirement for mental health screening and referral process in level 1 and level 2 trauma centers. However, implementation of these programs has been limited. One barrier to implementation has been the lack of cross-trained trauma and health psychologists to support the development and implementation of trauma-focused programs in acute and critical care settings. This paper is a call to action to bring together experts in the fields of trauma and health psychology to effectively address training gaps in post-injury PTSD and medical traumatic stress. Through development of trauma and health psychology cross-training models, the field of psychology can collaborate to meet the increasing demand for trauma-focused psychologists in acute and critical care settings.

A cross-sectional study about coronavirus fear of Chinese college students in school lockdowns during the COVID-19 pandemic

Objective

To remove the phobic psychological situation of Chinese college students who were in school lockdowns during the COVID-19 outbreak, and to provide a theoretical basis for college student psychological intervention.

Methods

Online survey conducted from December 9, 2021, to December 11, 2021. The seven-item Fcv-19s was employed to assess fear of COVID-19 on a Likert five-point scale. Categorical data were reported as number and percentage, whereas continuous data were reported as mean ± standard deviation. Multivariate logistic regression models were used to assess the association between different factors and anxiety symptoms.

Results

The study population consisted of 26.02% (268) male and 73.98% (762) female, of whom approximately 84% were undergraduates. The overall mean score of the questionnaire was 16.04 ± 5.28. Significantly more study populations reported high levels of fear (54.8%), while age, cost of life, professional category, education background (P < 0.05) revealed significant differences based on fear levels.

Conclusions

More than half of the Chinese college students developed fear symptoms during the COVID-19 epidemic. Appropriate psychological interventions for college students should be implemented promptly to reduce the psychological harm induced by the COVID-19 epidemic.

The potential impact of Covid-19 on CNS and psychiatric sequels

Due to its high prevalence and fatality, the current Severe Acute Respiratory Syndrome-coronavirus-2 (SARS-CoV-2) virus, which first emerged in China in 2019, quickly spread around the world and immediately became a serious global health concern. Although respiratory issues were initially the most prominent symptom of coronavirus disease 2019 (COVID-19), it became obvious rapidly that COVID-19, like many other coronavirus family members, could affect the central nervous system (CNS). During the pandemic, CNS involvement expressed itself in a variety of forms, including insomnia, anosmia, headaches, encephalopathies, encephalitis, cerebrovascular accidents, cognitive and memory impairment, and increased psychiatric disorders. Almost everyone who has been infected has at least one of these neurological symptoms, demonstrating that the virus has a high ability to impact the CNS. As the coronavirus pandemic passes its second year, the manifestations it can cause in the long run, such as its psychological sequels, have not yet been thoroughly studied. Given the high importance of this issue in today's society and due to the lack of reliable knowledge about the COVID-19 landscape on psychiatric disorders, we intend to investigate coronavirus's possible effect on mental illnesses based on available literature. Because the majority of the psychological effects of the coronavirus can continue for a long period after the pandemic ends, our research can give insight into potential psychiatric sequels associated with COVID-19.

Post-traumatic stress disorder: a psychiatric disorder requiring urgent attention

Post-traumatic stress disorder (PTSD) is a severe and heterogenous psychiatric disorder that was first defined as a mental disorder in 1980. Currently, the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) and the International Classification of Diseases 11th Edition (ICD-11) offer the most widely accepted diagnostic guidelines for PTSD. In both diagnostic categories, experiencing a traumatic event (TE) is the necessary criterion for diagnosing PTSD. The TEs described in the DSM-5 include actual or threatened death, serious injury, sexual violence, and other extreme stressors, either directly or indirectly. More than 70% of adults worldwide are exposed to a TE at least once in their lifetime, and approximately 10% of individuals develop PTSD after experiencing a TE. The important features of PTSD are intrusion or re-experiencing fear memories, pervasive sense of threat, active avoidance, hyperarousal symptoms, and negative alterations of cognition and mood. Individuals with PTSD have high comorbidities with other psychiatric diseases, including major depressive disorder, generalized anxiety disorder, and substance use disorder. Multiple lines of evidence suggest that the pathophysiology of PTSD is complex, involving abnormal neural circuits, molecular mechanisms, and genetic mechanisms. A combination of both psychotherapy and pharmacotherapy is used to treat PTSD, but has limited efficacy in patients with refractory PTSD. Because of the high prevalence, heavy burden, and limited treatments, PTSD is a psychiatric disorder that requires urgent attention. In this review, we summarize and discuss the diagnosis, prevalence, TEs, pathophysiology, and treatments of PTSD and draw attention to its prevention.

Early Interventions to Prevent Post-Traumatic Stress Disorder in Youth after Exposure to a Potentially Traumatic Event: A Scoping Review

The worldwide occurrence of potentially traumatic events (PTEs) in the life of children is highly frequent. We aimed to identify studies on early mental health interventions implemented within three months of the child/adolescent’s exposure to a PTE, with the aim of reducing acute post-traumatic symptoms, decreasing long term PTSD, and improving the child’s adjustment after a PTE exposure. The search was performed in PubMed and EMBASE databases resulting in twenty-seven articles meeting our inclusion criteria. Most non-pharmacological interventions evaluated had in common two complementary components: psychoeducation content for both children and parents normalizing early post-traumatic responses while identifying post-traumatic symptoms; and coping strategies to deal with post-traumatic symptoms. Most of these interventions studied yielded positive results on outcomes with a decrease in post-traumatic, anxiety, and depressive symptoms. However, negative results were noted when traumatic events were still ongoing (war, political violence) as well as when there was no or little parental involvement. This study informs areas for future PTSD prevention research and raises awareness of the importance of psychoeducation and coping skills building in both youth and their parents in the aftermath of a traumatic event, to strengthen family support and prevent the occurrence of enduring post-traumatic symptoms.

Implementation of a Psychiatric Consultation for Healthcare Workers during First Wave of COVID-19 Outbreak

BACKGROUND

Prevention and management strategies of mental suffering in healthcare workers appeared as important challenges during the COVID-19 pandemic. This article aims to: (1) show how potential psychiatric disorders for healthcare workers (HCW) during the first wave of the COVID-19 outbreak were identified; (2) present an activity report of this consultation; and (3) analyze and learn from this experience for the future.

METHODS

We performed a retrospective quantitative analysis of socio-demographic and clinical data, in addition to psychiatric scales scores for the main potential psychiatric risks (PDI, PDEQ, PCL-5, HADS, MBI-HSS) and post-hoc qualitative analysis of written interviews.

RESULTS

Twenty-five healthcare workers consulted between 19 March 2020 and 12 June 2020. We found 78.57% presented high peritraumatic dissociation and peritraumatic distress, 68.75% had severe anxiety symptoms, and 31.25% had severe depression symptoms. Concerning burnout, we found that 23.53% had a high level of emotional exhaustion. In the qualitative analysis of the written interview, we found a direct link between stress and the COVID-19 pandemic, primarily concerning traumatic stressors, and secondarily with work-related stress.

CONCLUSIONS

Early detection of traumatic reactions, valorization of individual effort, and limitations on work overload appear like potential key preventive measures to prevent psychiatric complications for healthcare workers in the context of the COVID-19 pandemic.

A randomized controlled trial of the influence of yoga for women with symptoms of post-traumatic stress disorder

Background

Survivors in motor vehicle accident (MVA) may have posttraumatic stress disorder (PTSD). Yoga is a complementary approach for PTSD therapy.

Methods

This randomized controlled trial explored whether yoga intervention has effects on reducing the symptoms of PTSD in women survived in MVA. Participants (n = 94) were recruited and randomized into control group or yoga group. Participants attended 6 45-minuite yoga sessions in 12 weeks. Depression Anxiety Stress Scales (DASS) and Impact of Events Scale-Revised (IES-R) were used to assess psychological distress.

Results

Post-intervention IES-R total score of yoga group was significantly lower than that of control group (p = 0.01). At both post-intervention and 3-months post intervention, the DASS-21 total scores of yoga group were both significantly lower than those of control group (p = 0.043, p = 0.024). Yoga group showed lower anxiety and depression level compared to control group at both post-intervention (p = 0.033, p < 0.001) and post-follow-up (p = 0.004, p = 0.035). Yoga group had lower levels of intrusion and avoidance compared to control group after intervention (p = 0.002, p < 0.001).

Conclusion

Results illustrate that yoga intervention may alleviate anxiety and depression and improve the symptoms of PTSD in women with PTSD following MVA.

Prevalence and Risk Factors of Post-Traumatic Stress Disorder in Survivors of a Cohort of Road Accident Victims in Benin: Results of a 12-Month Cross-Sectional Study

Purpose

Post-traumatic stress disorder (PTSD) is a frequent psychiatric complication in road accident survivors. However, it remains under-explored and is not taken into account in health policies in Benin. The purpose of this study was to determine the prevalence and risk factors of PTSD after a road traffic accident. This will help to improve its diagnosis and management in Benin hospitals.

Materials and Methods

An institution-based cross-sectional study was conducted from November 2020 to January 2021. Consenting victims of road traffic accidents from three hospitals across Benin, aged 18 years and above, living in the south of the country, were administered various questionnaires at 12-month follow-up. Data on PTSD were collected using a pre-tested, structured and standardized post-traumatic stress disorder questionnaire, the PTSD Checklist (specific version) (PCL-S). A logistic regression model was fitted to identify factors associated with PTSD. An adjusted odds ratio (AOR) followed by a 95% confidence interval was calculated to determine the level of significance with a p-value less than 0.05.

Results

Out of 865 patients in the cohort eligible for the 12-month follow-up, 734 (85%) participated in the study. The prevalence of PTSD was 26.43% (95% CI: 23.36–29.75). Factors associated with PTSD on multivariate analysis were female gender (adjusted odds ratio (AOR) = 2.14, 95% CI: 1.38–3.33), hospitalization (AOR = 1.87, 95% CI 1.21–2.89), negative impact of the accident on income (AOR = 4.22, 95% CI: 2.16–8.25), and no return to work (AOR = 3.17, 95% CI: 1.99–5.06).

Conclusion

The prevalence of PTSD is high in road accident survivors in Benin. The results of this study highlight the need for early diagnosis and a multidisciplinary approach to the management of PTSD patients in Benin’s hospitals.

Post-Traumatic Stress in Vitiligo Patients: A Neglected but Real-Existing Psychological Impairment

Background

Vitiligo is the most common depigmentation disorder. This disease causes disfiguration and induces psychological burdens, leading to significantly impaired quality of life. Limited research about disease-related post-traumatic stress (PTS) has been conducted in vitiligo patients.

Objective

To evaluate the prevalence, severity, and risk factors of post-traumatic stress in vitiligo patients.

Methods

This case-control study was performed from January 2021 to April 2021. A survey questionnaire including baseline information, post-traumatic stress symptoms evaluation, life quality evaluation was conducted. According to the severity of post-traumatic stress symptoms, patients were grouped and compared. The logistic regression model was conducted to analyze the risk factors for post-traumatic stress disorder (PTSD).

Results

A total of 337 patients were included. A 30.3% of vitiligo patients (102/337) in present cohort had PTS and 12.5% patients (42/337) were confirmed for developing into PTSD. The multivariate logistic regression revealed educational level<university (OR=2.32, 95% CI=1.97–2.93, P=0.003), vitiligo in face and neck (OR=2.65, 95% CI=2.08–3.12, P=0.008), vitiligo in feet and hands (OR=1.86, 95% CI=1.54–2.12, P<0.001) and surgical treatment (OR=3.53, 95% CI=3.12–4.02, P<0.001) were risk factors for PTSD. PTS severity was significantly associated with vitiligo disease activity score (rho=0.54, R2=0.29, P=0.002), vitiligo area scoring index score (r=0.55, R2=0.30, P=0.012), and dermatology life quality index score (r=0.61, R2=0.37, P=0.004).

Conclusion

Vitiligo-related PTS is prevalent in vitiligo patients and causes psychological impairment. Dermatologists should realize and identify this condition carefully and offer proactive intervention to improve patients’ quality of life.

Revealing Unknown Benefits of Existing Medications to Aid the Discovery of New Treatments for Post‐Traumatic Stress Disorder

Objective

To systematically identify novel pharmacological strategies for preventing or treating post‐traumatic stress disorder (PTSD) by leveraging large‐scale analysis of real‐world observational data.

Methods

Using a self‐controlled study design, the association between 1399 medications and the incidence of PTSD across four US insurance claims databases covering commercially insured, Medicare eligible, and Medicaid patients was examined. A validated algorithm for identifying PTSD in claims data was used, and medications were identified by their RxNorm ingredient. Medications used to treat PTSD or its symptoms (e.g., antidepressants, antipsychotics) were excluded. Medications associated with ≥30% reduction in risk of PTSD in ≥2 databases were identified.

Results

A total of 137,182,179 individuals were included in the analysis. Fifteen medications met the threshold criteria for a potential protective effect on PTSD; six were categorized as “primary signals” while the remaining nine were considered “potential signals”. The primary signals include a beta blocker that has been previously studied for PTSD, and five medications used to treat attention‐deficit/hyperactivity disorder. The potential signals include four medications used to treat substance use disorders and five medications used to treat sleep disorders.

Discussion

The medications identified in this analysis provide targets for further research in studies that are designed to examine specific hypotheses regarding these medications and the incidence of PTSD. This work may aid in discovering novel therapeutic approaches to treat PTSD, wherein new and effective treatments are badly needed.

Four large US‐based administrative claims databases were used to analyze the association between all marketed prescription medications and the outcome of incident post‐traumatic stress disorder (PTSD)

Of the 1399 medications examined, there were 15 that met the strict filtering criteria for showing consistent, moderate‐to‐strong, protective effects against the outcome

Medications fell into four main classes: (1) a beta blocker (propranolol), (2) five medications used to treat attention‐deficit/hyperactivity disorder (ADHD), (3) four medications used to treat substance use disorders and (4) five medications used to treat sleep disorders

These findings identify rational starting points for future hypothesis‐driven research to explore these associations in greater detail

Early pharmacological interventions for universal prevention of post-traumatic stress disorder (PTSD)

BACKGROUND

Post-traumatic stress disorder (PTSD) is a severe and debilitating condition. Several pharmacological interventions have been proposed with the aim to prevent or mitigate it. These interventions should balance efficacy and tolerability, given that not all individuals exposed to a traumatic event will develop PTSD. There are different possible approaches to preventing PTSD; universal prevention is aimed at individuals at risk of developing PTSD on the basis of having been exposed to a traumatic event, irrespective of whether they are showing signs of psychological difficulties.

OBJECTIVES

To assess the efficacy and acceptability of pharmacological interventions for universal prevention of PTSD in adults exposed to a traumatic event.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trial Register (CCMDCTR), CENTRAL, MEDLINE, Embase, two other databases and two trials registers (November 2020). We checked the reference lists of all included studies and relevant systematic reviews. The search was last updated on 13 November 2020.

SELECTION CRITERIA

We included randomised clinical trials on adults exposed to any kind of traumatic event. We considered comparisons of any medication with placebo or with another medication. We excluded trials that investigated medications as an augmentation to psychotherapy.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures. In a random-effects model, we analysed dichotomous data as risk ratios (RR) and number needed to treat for an additional beneficial/harmful outcome (NNTB/NNTH). We analysed continuous data as mean differences (MD) or standardised mean differences (SMD).

MAIN RESULTS

We included 13 studies which considered eight interventions (hydrocortisone, propranolol, dexamethasone, omega-3 fatty acids, gabapentin, paroxetine, PulmoCare enteral formula, Oxepa enteral formula and 5-hydroxytryptophan) and involved 2023 participants, with a single trial contributing 1244 participants. Eight studies enrolled participants from emergency departments or trauma centres or similar settings. Participants were exposed to a range of both intentional and unintentional traumatic events. Five studies considered participants in the context of intensive care units with traumatic events consisting of severe physical illness. Our concerns about risk of bias in the included studies were mostly due to high attrition and possible selective reporting. We could meta-analyse data for two comparisons: hydrocortisone versus placebo, but limited to secondary outcomes; and propranolol versus placebo. No study compared hydrocortisone to placebo at the primary endpoint of three months after the traumatic event. The evidence on whether propranolol was more effective in reducing the severity of PTSD symptoms compared to placebo at three months after the traumatic event is inconclusive, because of serious risk of bias amongst the included studies, serious inconsistency amongst the studies' results, and very serious imprecision of the estimate of effect (SMD -0.51, 95% confidence interval (CI) -1.61 to 0.59; I² = 83%; 3 studies, 86 participants; very low-certainty evidence). No study provided data on dropout rates due to side effects at three months post-traumatic event. The evidence on whether propranolol was more effective than placebo in reducing the probability of experiencing PTSD at three months after the traumatic event is inconclusive, because of serious risk of bias amongst the included studies, and very serious imprecision of the estimate of effect (RR 0.77, 95% CI 0.31 to 1.92; 3 studies, 88 participants; very low-certainty evidence). No study assessed functional disability or quality of life.  Only one study compared gabapentin to placebo at the primary endpoint of three months after the traumatic event, with inconclusive evidence in terms of both PTSD severity and probability of experiencing PTSD, because of imprecision of the effect estimate, serious risk of bias and serious imprecision (very low-certainty evidence). We found no data on dropout rates due to side effects, functional disability or quality of life. For the remaining comparisons, the available data are inconclusive or missing in terms of PTSD severity reduction and dropout rates due to adverse events. No study assessed functional disability.

AUTHORS' CONCLUSIONS

This review provides uncertain evidence only regarding the use of hydrocortisone, propranolol, dexamethasone, omega-3 fatty acids, gabapentin, paroxetine, PulmoCare formula, Oxepa formula, or 5-hydroxytryptophan as universal PTSD prevention strategies. Future research might benefit from larger samples, better reporting of side effects and inclusion of quality of life and functioning measures.

Utility of 7,8-dihydroxyflavone in preventing astrocytic and synaptic deficits in the hippocampus elicited by PTSD

Astrocytic functions and brain-derived neurotrophic factor (BDNF)-tyrosine kinase receptor B (TrkB) signaling pathways are impaired in stress-related neuropsychiatric diseases. Previous studies have reported neuroprotective effects of 7,8-dihydroxyflavone (7,8-DHF), a TrkB activator. Here, we investigated the molecular mechanisms underlying pathogenesis of post-traumatic stress disorder (PTSD) using a modified single-prolonged stress (SPS&S) model and the potential beneficial effects of 7,8-DHF. SPS&S reduced the hippocampal expression of glial fibrillary acidic protein (GFAP), a marker of astrocytes, and induced morphological changes in astrocytes. From the perspective of synaptic function, the SPS&S model displayed reduced expression of BDNF, p-TrkB, postsynaptic density protein 95 (PSD95), AMPA receptor subunit GluR1 (GluA1), NMDA receptor subunit N2A/N2B ratio, calpain-1, phosphorylated protein kinase B (Akt) and phosphorylated mammalian target of rapamycin (mTOR) and conversely, higher phosphatase and tension homolog (PTEN) expression in the hippocampus. Acute or continuous intraperitoneal administration of 7,8-DHF (5 mg/kg) after SPS&S procedures prevented SPS&S-induced fear memory generalization and anxiety-like behaviors as well as abnormalities of hippocampal oscillations. Most importantly, 7,8-DHF attenuated SPS&S-induced abnormal BDNF-TrkB signaling and calpain-1-dependent cascade of synaptic deficits. Furthermore, treatment with a TrkB inhibitor completely blocked while an mTOR inhibitor partially blocked the effects of 7,8-DHF on behavioral changes of SPS&S model mice. Our collective findings suggest that 7,8-DHF effectively alleviates PTSD-like symptoms, including fear generalization and anxiety-like behavior, potentially by preventing astrocytic and synaptic deficits in the hippocampus through targeting of TrkB.

Predictors of Family Engagement in Child Post-Traumatic Stress Disorder Screening Following Exposure to Intimate Partner Violence

Children's exposure to intimate partner violence (IPV) has numerous negative short- and long-term impacts on children's development, mental health, physical health, and adult functioning. While community-based organizations have an array of interventions aimed to increase survivor safety and prevent the development of, or treat post-traumatic stress disorder (PTSD), many families experiencing IPV never enter the doors of community-based organizations. To address this gap, there is an increasing number of partnerships between community-based organizations and first responders to increase support to families experiencing IPV. The Child Trauma Response Team (CTRT) is an innovative model that provides a coordinated, immediate, trauma-informed, and interdisciplinary response to families exposed to IPV. Given the lack of research on coordinated community interventions, the research questions for this study were as follows: (a) What are the family sociodemographic factors, crime factors, and program services most associated with family engagement in child PTSD screening following exposure to IPV? (b) What are the family sociodemographic factors and crime factors most associated with children screening positive for PTSD following exposure to IPV? The data for this study consist of 244 families with 352 children identified by the pilot CTRT. The results of this study suggest that a collaborative intervention designed to address caregiver and children's safety and well-being after a police-reported IPV incident is a promising model. Overall, more than 70% of children identified by the CTRT team completed a child PTSD screen, and 74.3% of children who completed the screens were screened positive for PTSD. The safety assessment service provided by the CTRT team was a predictor of the families' engagement in child PTSD screens. This is a critical finding and suggests the importance of developing program models that comprehensively address the needs of caregivers and children exposed to IPV.

Somatic Symptom Severity, Not Injury Severity, Predicts Probable Posttraumatic Stress Disorder and Major Depressive Disorder in Wounded Service Members

Although previous studies have reported an association between patient-reported somatic symptom severity and the development of posttraumatic stress disorder (PTSD) or major depressive disorder (MDD) in injured military service members (SMs), conclusions from other studies regarding the association between clinician-determined injury severity and PTSD or MDD remain unclear. The present study investigated whether somatic symptoms or injury severity predict the development of probable PTSD or MDD in wounded SMs medically evacuated from combat areas. Data including SM demographic characteristics, clinician-determined injury severity (i.e., Injury Severity Score [ISS] and Abbreviated Injury Scale [AIS] values), and self-report assessments of PTSD (PTSD Checklist-Civilian Version), MDD (Patient Health Questionnaire [PHQ]-9), and somatic symptoms (PHQ-15) were analyzed. A total of 2,217 SMs completed at least one self-assessment between 2003 and 2014, with 425 having completed assessments at each assessment period (AP), conducted 1-75 (AP1), 76-165 (AP2), and 166-255 (AP3) days postinjury. Between AP1 and AP3, the rates of probable PTSD and MDD increased from 3.0% to 11.7% and from 2.8% to 9.2%, respectively. Somatic symptom severity at AP1 predicted probable PTSD and MDD at all three APs, odds ratios (ORs) = 3.5-11.5; however, ISS values did not predict probable PTSD or MDD at any AP, ORs = 0.6-0.9. This suggests that the initial severity of self-reported somatic symptoms rather than clinician-determined injury severity predicts the development of probable PTSD and MDD in wounded SMs.

The Impact of the COVID-19 Pandemic on Mental Health, Occupational Functioning, and Professional Retention Among Health Care Workers and First Responders

BACKGROUND

The COVID-19 pandemic has greatly affected front-line health care workers (HCW) and first responders (FR). The specific components of COVID-19 related occupational stressors (CROS) associated with psychiatric symptoms and reduced occupational functioning or retention remain poorly understood.

OBJECTIVES

Examine the relationships between total and factored CROS, psychiatric symptoms, and occupational outcomes.

DESIGN

Observational, self-report, single time-point online assessment.

PARTICIPANTS

A total of 510 US HCW (N = 301) and FR (N = 200) with occupational duties affected by the COVID-19 pandemic.

MAIN OUTCOMES AND MEASURES

CROS were assessed using a custom 17-item questionnaire. Post-traumatic stress disorder (PTSD), depression, insomnia, and generalized anxiety symptoms were assessed using the PTSD Checklist-5 (PCL5), Patient Health Questionnaire-9 (PHQ9), Insomnia Severity Index (ISI), and General Anxiety Disorder-7 (GAD7). Respondents' likelihood of leaving current field and occupational functioning were assessed with 2-item PROMIS subscales. Relationships were modeled using multivariable regression. Open-ended responses were coded using rapid template analysis.

RESULTS

CROS total scores correlated significantly with all four psychiatric symptom domains (R's = .42-.53), likelihood of leaving one's current occupation (R = .18), and trouble doing usual work (R = .28), all p's < .001. Half of HCW indicated a decreased likelihood of staying in their current occupation as a result of the pandemic. CROS were fit to a 3-factor model consisting of risk, demoralization, and volume factors. All CROS factors were associated with psychiatric symptom burden, but demoralization was most prominently associated with psychiatric symptoms and negative occupational outcomes. Among psychiatric symptoms, PTSD symptoms were most strongly associated with negative occupational outcomes. Open-ended statements emphasized lack of protection and support, increased occupational demands, and emotional impact of work duties.

CONCLUSIONS AND RELEVANCE

These results demonstrate potentially treatable psychiatric symptoms in HCW and FR experiencing CROS, impacting both wellbeing and the health care system. Mitigating CROS, particularly by addressing factors driving demoralization, may improve HCW and FR mental health, occupational functioning, and retention.

Effects of Sevoflurane and Propofol on Posttraumatic Stress Disorder After Emergency Trauma: A Double-Blind Randomized Controlled Trial

OBJECTIVE

Posttraumatic stress disorder (PTSD) is a frequent and disabling consequence of traumatic events. A previous study found that early use of propofol was a potential risk factor for PTSD. This prospective study aimed to investigate the effect of propofol and sevoflurane on PTSD after emergency surgery in trauma patients.

METHODS

A total of 300 trauma patients undergoing emergency surgery were randomly divided into two groups and anesthetized with propofol and/or sevoflurane. Perioperative clinical data were collected. The incidence of PTSD was evaluated with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) in the two groups 1 month after the operation. The relevance of the injury time and CAPS-5 scores was assessed by Spearman correlation analysis. Logistic regression analysis was used to analyze the risk factors for PTSD.

RESULTS

The incidence of PTSD in the propofol group was higher than that in the sevoflurane group 1 month postoperatively (23.2 vs. 12.2%, P = 0.014). The injury time was negatively correlated with the CAPS-5 score in the propofol group (r = -0.226, P < 0.001). In the logistic regression analysis, the utilization of propofol was an independent risk factor for PTSD (P = 0.017).

CONCLUSION

Early use of propofol general anesthesia in emergency surgery for trauma patients may increase the risk of PTSD.

Recognizing and Reducing the Impact of Trauma of Hospitalization: Considerations for Persons Who Use Drugs

Amidst the ongoing opioid crisis, the number of individuals with substance use disorders being hospitalized for acute medical illnesses has increased. There is now a growing recognition that these events may be psychologically traumatic, leading to the development of acute stress reactions, and post-traumatic stress disorder. Patients who use drugs may be particularly susceptible to being traumatized due to their underlying psychiatric comorbidities, prior trauma histories, inadequate treatment of the underlying substance use disorders, and stigmatization. Interventions such as early identification and screening, trauma-informed care, and specialized addiction services may help to mitigate the risks of trauma amongst this population. More research is needed to better guide hospitals to ensure people who use drugs receive optimal care.

Molecular Mechanism of the ATF6α/S1P/S2P Signaling Pathway in Hippocampal Neuronal Apoptosis in SPS Rats

Apoptosis of hippocampal neurons is one of the mechanisms of hippocampal atrophy in posttraumatic stress disorder (PTSD), and it is also an important cause of memory impairment in PTSD patients. Endoplasmic reticulum stress (ERS) mediated by activated transcription factor 6α (ATF6α)/site 1 protease (S1P)/S2P is involved in cell apoptosis, but it is not clear whether it is involved in hippocampal neuron apoptosis caused by PTSD. A PTSD rat model was constructed by the single prolonged stress (SPS) method. The study was divided into three parts. Experiment 1 included the control group, SPS 1 d group, SPS 7 d group, and SPS 14 d group. Experiment 2 included the control group, SPS 7 d group, SPS 7 d + AEBSF group, and control + AEBSF group. (4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF) is an ATF6α pathway inhibitor). Experiment 3 included the control group, SPS 4 d group, SPS 4 d + AEBSF group, and control + AEBSF group. The protein and mRNA expression levels of ATF6α, glucose-regulated protein (GRP78), S1P, S2P, C/EBP homologous protein (CHOP), and caspase-12 in the hippocampus of PTSD rats were detected by immunohistochemistry, Western blotting and qRT-PCR. Apoptosis of hippocampal neurons was detected by TUNEL staining. In experiment 1, the protein and mRNA expression of ATF6α and GRP78 increased gradually in the SPS 1 d group and the SPS 7 d group but decreased in the SPS 14 d group (P < 0.01). In experiment 2, compared with that in the control group, the protein and mRNA expression of ATF6α, GRP78, S1P, S2P, CHOP, and caspase-12 and the apoptosis rate were significantly increased in the SPS 7 d group (P < 0.01). However, the protein and mRNA expression of ATF6α, GRP78, S1P, S2P, CHOP, and caspase-12 and the apoptosis rate were significantly decreased after AEBSF pretreatment (P < 0.01). In experiment 3, compared with that in the control group, the protein and mRNA expression of ATF6α, GRP78, S1P, S2P, CHOP, and caspase-12 and the apoptosis rate were increased in the SPS 14 d group (P < 0.05). However, the protein and mRNA expression of ATF6α, GRP78, S1P, S2P, CHOP, and caspase-12 and the apoptosis rate were decreased after AEBSF pretreatment (P < 0.05). SPS induced apoptosis of hippocampal neurons by activating ERS mediated by ATF6α, suggesting that ERS-induced apoptosis is involved in the occurrence of PTSD.

Prevalence and risk factors for acute stress disorder in female victims of sexual assault

Sexual assault is one of the most traumatic events a person can experience. Despite this, information regarding the risk factors associated with the development of Acute Stress Disorder (ASD) in sexual assault victims is scarce. A follow-up prospective cohort study was designed to examine the prevalence and risk factors of ASD in women exposed to a recent sexual assault. A total of 156 women were treated at the Emergency Department of a university general hospital shortly after sexual assault. Sociodemographic, clinical and sexual assault-related variables were collected. The Acute Stress Disorder Interview was used to estimate the prevalence of ASD at three weeks post-SA. From the 156 victims, 66.6% (N = 104) met ASD diagnosis using DSM-5 criteria, whereas 59.6% (N = 93) met ASD diagnosis using DSM-IV criteria. The risk factors associated with the development of ASD were nationality, psychiatric history, peritraumatic dissociation and type of assault. In conclusion, the prevalence of ASD in female victims of recent sexual assault was high, affecting approximately two thirds of them. The recognition of the risk factors associated with ASD development, like peritraumatic dissociation or type of assault, may aid in the prompt detection of vulnerable women that require early and specific interventions shortly after trauma.

Development and Validation of a Model to Predict Posttraumatic Stress Disorder and Major Depression After a Motor Vehicle Collision

IMPORTANCE

A substantial proportion of the 40 million people in the US who present to emergency departments (EDs) each year after traumatic events develop posttraumatic stress disorder (PTSD) or major depressive episode (MDE). Accurately identifying patients at high risk in the ED would facilitate the targeting of preventive interventions.

OBJECTIVES

To develop and validate a prediction tool based on ED reports after a motor vehicle collision to predict PTSD or MDE 3 months later.

DESIGN, SETTING, AND PARTICIPANTS

The Advancing Understanding of Recovery After Trauma (AURORA) study is a longitudinal study that examined adverse posttraumatic neuropsychiatric sequalae among patients who presented to 28 US urban EDs in the immediate aftermath of a traumatic experience. Enrollment began on September 25, 2017. The 1003 patients considered in this diagnostic/prognostic report completed 3-month assessments by January 31, 2020. Each patient received a baseline ED assessment along with follow-up self-report surveys 2 weeks, 8 weeks, and 3 months later. An ensemble machine learning method was used to predict 3-month PTSD or MDE from baseline information. Data analysis was performed from November 1, 2020, to May 31, 2021.

MAIN OUTCOMES AND MEASURES

The PTSD Checklist for DSM-5 was used to assess PTSD and the Patient Reported Outcomes Measurement Information System Depression Short-Form 8b to assess MDE.

RESULTS

A total of 1003 patients (median [interquartile range] age, 34.5 [24-43] years; 715 [weighted 67.9%] female; 100 [weighted 10.7%] Hispanic, 537 [weighted 52.7%] non-Hispanic Black, 324 [weighted 32.2%] non-Hispanic White, and 42 [weighted 4.4%] of non-Hispanic other race or ethnicity were included in this study. A total of 274 patients (weighted 26.6%) met criteria for 3-month PTSD or MDE. An ensemble machine learning model restricted to 30 predictors estimated in a training sample (patients from the Northeast or Midwest) had good prediction accuracy (mean [SE] area under the curve [AUC], 0.815 [0.031]) and calibration (mean [SE] integrated calibration index, 0.040 [0.002]; mean [SE] expected calibration error, 0.039 [0.002]) in an independent test sample (patients from the South). Patients in the top 30% of predicted risk accounted for 65% of all 3-month PTSD or MDE, with a mean (SE) positive predictive value of 58.2% (6.4%) among these patients at high risk. The model had good consistency across regions of the country in terms of both AUC (mean [SE], 0.789 [0.025] using the Northeast as the test sample and 0.809 [0.023] using the Midwest as the test sample) and calibration (mean [SE] integrated calibration index, 0.048 [0.003] using the Northeast as the test sample and 0.024 [0.001] using the Midwest as the test sample; mean [SE] expected calibration error, 0.034 [0.003] using the Northeast as the test sample and 0.025 [0.001] using the Midwest as the test sample). The most important predictors in terms of Shapley Additive Explanations values were symptoms of anxiety sensitivity and depressive disposition, psychological distress in the 30 days before motor vehicle collision, and peritraumatic psychosomatic symptoms.

CONCLUSIONS AND RELEVANCE

The results of this study suggest that a short set of questions feasible to administer in an ED can predict 3-month PTSD or MDE with good AUC, calibration, and geographic consistency. Patients at high risk can be identified in the ED for targeting if cost-effective preventive interventions are developed.
