The prevalence of PTSD and major depression in the global population of adult war survivors: a meta-analytically informed estimate in absolute numbers

Risk Phenotypes, Comorbidities, Pharmacotherapy, and Electroconvulsive Therapy (ECT) in a Cohort with Difficult-to-Treat Depression in Comparison to an Unmedicated Control Group

BACKGROUND

Approximately 15-25% of depressed patients suffer from difficult-to-treat depression (DTD). Patients with DTD require a thorough examination to avoid the oversight of treatable (psychiatric/somatic) comorbidities or (pseudo-)resistance to antidepressant drugs (ADs). Polymorphisms of the cytochrome P450 (CYP) enzymes 2D6 and 2C19, which play a major role in the metabolism of ADs, may contribute to resistance to ADs. Patients with DTD might benefit from electroconvulsive therapy (ECT).

METHODS

We enrolled 109 patients with DTD and 29 untreated depressed controls (UDC). We assessed risk phenotypes, comorbidities, and treatment, including ECT. We also performed pharmacokinetic analyses of CYP2D6 and CYP2C19.

RESULTS

DTD patients significantly more often suffered from comorbid psychiatric diseases, especially ICD-10: F40-F48 (DTD:40.4%, UDC:17.2%, OR 11.87, p=0.011) than UDC patients. DTD patients receiving ECT were more likely to achieve remission (37.7% vs. 11.8%, OR=3.96, p=0.023). Treatment with ADs did not differ between remitters and non-remitters. No significant differences were observed in the distribution of CYP2D6 and CYP2C19 variants between both groups.

CONCLUSION

Patients with DTD appear to experience comorbid neurotic stress and somatoform disorders (ICD-10: F40 - F48) more frequently. Therefore, a comprehensive differential diagnosis is crucial when patients do not respond sufficiently to antidepressant medication. Genotyping CYP2D6 and CYP2C19 should be considered.

New social identities in Ukrainian 'refugees': A social cure or social curse?

Experiencing traumatic events often drives profound post-traumatic stress (PTS), but trauma also has the potential to engender positive consequences, such as post-traumatic growth (PTG). Traumatic experiences may also lead to gaining new identities which can have both protective (i.e., social cure) or damaging (i.e., social curse) effects on health and well-being. This study aims to examine the role of new social identities and related social identity resources acquired after war-related experiences (i.e., identification with a new host society and identification as a refugee) in contributing to different trauma trajectories. The sample included 468 participants who left Ukraine due to the war that commenced on February 24th, 2022, and became residents of Ireland or Poland. The findings indicate that identification with the host society was associated with lower PTS and greater PTG. Whereas identification with refugees was related to higher PTS, but it was not directly associated with PTG. Further, the psychological resources derived from these new identities mediated the relationship between identification strength and PTG. This study offers practical insights for interventions targeting refugees in their new countries of residence.

Prevalence of Post-Traumatic Stress Disorder and Depression and Associated Factors Among Internally Displaced Persons in Al-Galgala, Sudan

Purpose

Conflict and war can have profound psychological and physical consequences, including the displacement of civilians. Sudan currently has the greatest child displacement crisis and the highest number of displaced individuals worldwide. Stressors, such as unemployment, poor socioeconomic conditions, and lack of social integration can increase the risk of developing mental health conditions and worsen pre-existing ones. This study aims to determine the prevalence of PTSD and depression and to investigate the association of sociodemographic and displacement characteristics with both PTSD and depression.

Patients and Methods

An observational descriptive cross-sectional community-based study was conducted among 143 IDPs, in Al-Galgala village, Sudan. The data was collected by seven, well-trained individuals over 2 weeks. The PTSD Checklist - Civilian version (PCL-C) scale was used for PTSD symptoms, and the Patient Health Questionnaire 9 (PHQ-9) scale was used for depression symptoms. The diagnostic criteria for PTSD and depression symptoms were based on the Diagnostic and Statistical Manual (DSM-IV). Descriptive statistics and Binary Logistic Regression analysis were adopted to determine the predictors for PTSD and depression symptoms. A P-value of 0.05 or lower was considered statistically significant.

Results

The prevalence of PTSD symptoms was found to be 25% based on DSM-IV symptoms' criteria and that of depression was 62%. Moreover, 23.1% of the participants had comorbid depression and PTSD symptoms. Being female (AOR = 8.434, 95% CI [1.026-69.325]), and having depression increased the risk of developing PTSD (AOR = 45.631, 95% CI [7.125-292.232]). Whereas, being older (40-59 years) (AOR = 6.473, 95% CI [1.054-39.766]) and having PTSD (AOR = 24.736, 95% CI [4.928 -124.169]) increased the risk of developing depression.

Conclusion

The estimated prevalence of PTSD and depression among IDPs in Al-Galgala, Sudan was found to be relatively high. This study revealed that depression, gender, occupation, education, and with whom you are currently staying were significantly associated with PTSD. In contrast, factors associated with depression were PTSD, age, and the duration of exposure to the armed conflict. The mental health among IDPs needs to be prioritized by implementing effective programs and providing psychosocial support to civilians residing in post-conflict regions.

Ketamine's Amelioration of Fear Extinction in Adolescent Male Mice Is Associated with the Activation of the Hippocampal Akt-mTOR-GluA1 Pathway

Fear-related disorders, including post-traumatic stress disorder (PTSD), and anxiety disorders are pervasive psychiatric conditions marked by persistent fear, stemming from its dysregulated acquisition and extinction. The primary treatment for these disorders, exposure therapy (ET), relies heavily on fear extinction (FE) principles. Adolescence, a vulnerable period for developing psychiatric disorders, is characterized by neurobiological changes in the fear circuitry, leading to impaired FE and increased susceptibility to relapse following ET. Ketamine, known for relieving anxiety and reducing PTSD symptoms, influences fear-related learning processes and synaptic plasticity across the fear circuitry. Our study aimed to investigate the effects of ketamine (10 mg/kg) on FE in adolescent male C57 BL/6 mice at the behavioral and molecular levels. We analyzed the protein and gene expression of synaptic plasticity markers in the hippocampus (HPC) and prefrontal cortex (PFC) and sought to identify neural correlates associated with ketamine's effects on adolescent extinction learning. Ketamine ameliorated FE in the adolescent males, likely affecting the consolidation and/or recall of extinction memory. Ketamine also increased the Akt and mTOR activity and the GluA1 and GluN2A levels in the HPC and upregulated BDNF exon IV mRNA expression in the HPC and PFC of the fear-extinguished mice. Furthermore, ketamine increased the c-Fos expression in specific brain regions, including the ventral HPC (vHPC) and the left infralimbic ventromedial PFC (IL vmPFC). Providing a comprehensive exploration of ketamine's mechanisms in adolescent FE, our study suggests that ketamine's effects on FE in adolescent males are associated with the activation of hippocampal Akt-mTOR-GluA1 signaling, with the vHPC and the left IL vmPFC as the proposed neural correlates.

Factors associated with depression among war-affected population in Northeast, Ethiopia

BACKGROUND

Depression is the most common mental health outcome of exposure to war-related traumatic stressors. Due to inter-communal conflict, Dessie City residents have experienced prolonged armed conflict in 2021. This conflict leads to widespread violence, negative impact on mental health, and large-scale forced migration. However, the problem is not properly addressed in Ethiopia. Therefore, this study aimed to assess the prevalence and risk factors of depression in the war-affected area in Dessie City, Ethiopia.

METHOD

A cross-sectional study design was conducted among 785 participants in 2022. The study subjects were selected using a multi-stage cluster sampling technique. The outcome measures used in the study were validated with the Patient Health Questionnaire (PHQ-9). Data was entered using Epi-data version 3.1 and SPSS version 25 was used to analyze data. Bivariate and multivariable logistic regressions were done to identify factors related to depression. In multivariable logistic regression variables with a p-value less than 0.05 were considered significant and, adjusted OR (AOR) with 95% CI was used to present the strength of the association.

RESULT

The prevalence of depression among participants was found to be 24.5% (95% CI,21.7, 27.5). In multivariable analysis, post-traumatic stress disorder (AOR = 2.79, 95% CI 1.76-4.43), middle-perceived life threats (AOR = 8.25, 95% CI 2.47-17.49), low social support (AOR = 1.90, 95% CI 1.23-2.96) were variables significantly associated with depression.

CONCLUSION

This study found a high prevalence of depression among Dessie City residents. post-traumatic stress disorder, middle-perceived life threats, and low social support were associated with depression. Interventional strategies should be implemented to promote healing, resilience, and the overall well-being of individuals and communities. However, the findings underscore the need to address the current lack of mental health care resources in post-conflict populations.

The long-term spatio-temporal trends in burden and attributable risk factors of major depressive disorder at global, regional and national levels during 1990-2019: a systematic analysis for GBD 2019

AIMS

Caused by multiple risk factors, heavy burden of major depressive disorder (MDD) poses serious challenges to public health worldwide over the past 30 years. Yet the burden and attributable risk factors of MDD were not systematically known. We aimed to reveal the long-term spatio-temporal trends in the burden and attributable risk factors of MDD at global, regional and national levels during 1990-2019.

METHODS

We obtained MDD and attributable risk factors data from Global Burden of Disease Study 2019. We used joinpoint regression model to assess the temporal trend in MDD burden, and age-period-cohort model to measure the effects of age, period and birth cohort on MDD incidence rate. We utilized population attributable fractions (PAFs) to estimate the specific proportions of MDD burden attributed to given risk factors.

RESULTS

During 1990-2019, the global number of MDD incident cases, prevalent cases and disability-adjusted life years (DALYs) increased by 59.10%, 59.57% and 58.57%, respectively. Whereas the global age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR) and age-standardized DALYs rate (ASDR) of MDD decreased during 1990-2019. The ASIR, ASPR and ASDR in women were 1.62, 1.62 and 1.60 times as that in men in 2019, respectively. The highest age-specific incidence, prevalence and DALYs rate occurred at the age of 60-64 in women, and at the age of 75-84 in men, but the maximum increasing trends in these age-specific rates occurred at the age of 5-9. Population living during 2000-2004 had higher risk of MDD. MDD burden varied by socio-demographic index (SDI), regions and nations. In 2019, low-SDI region, Central sub-Saharan Africa and Uganda had the highest ASIR, ASPR and ASDR. The global PAFs of intimate partner violence (IPV), childhood sexual abuse (CSA) and bullying victimization (BV) were 8.43%, 5.46% and 4.86% in 2019, respectively.

CONCLUSIONS

Over the past 30 years, the global ASIR, ASPR and ASDR of MDD had decreased trends, while the burden of MDD was still serious, and multiple disparities in MDD burden remarkably existed. Women, elderly and populations living during 2000-2004 and in low-SDI regions, had more severe burden of MDD. Children were more susceptible to MDD. Up to 18.75% of global MDD burden would be eliminated through early preventing against IPV, CSA and BV. Tailored strategies-and-measures in different regions and demographic groups based on findings in this studywould be urgently needed to eliminate the impacts of modifiable risk factors on MDD, and then mitigate the burden of MDD.

Prevalence and associated factors of common mental disorders among internally displaced people by armed conflict in Cabo Delgado, Mozambique: a cross-sectional community-based study

Background

Humanitarian emergencies are a major global health challenge with the potential to have a profound impact on people's mental and psychological health. Displacement is a traumatic event that disrupts families and affects physical and psychological health at all ages. A person may endure or witness a traumatic incident, such as being exposed to war, and, as a result, develop post-traumatic stress disorder (PTSD). There is a lack of information about post-traumatic stress disorder, depression, and anxiety disorder in low and middle-income countries in humanitarian emergency contexts such as Mozambique. This study aimed to assess the prevalence of PTSD, depression, and anxiety, and associated factors among armed conflict survivors in Cabo Delgado, north region of Mozambique in 2023.

Methods

A community-based cross-sectional study was conducted between January and April 2023 among 750 participants, who were selected by convenience. A face-to-face interview used the Primary Care Post-Traumatic Stress Disorder Checklist (PC-PTSD-5) to evaluate PTSD, the Generalized Anxiety Disorder Scale (GAD-7) to evaluate anxiety and the Patient Health Questionnaire - Mozambique (PHQ-9 MZ) to evaluate depression. The association between PTSD and demographic and psychosocial characteristics was analyzed using bivariate and multivariable binary logistic regression. We used a 5% significance level.

Results

The three mental disorders assessed were highly prevalent in our sample with 74.3% PTSD, 63.8% depression, and 40.0% anxiety. The chance of developing PTSD was higher in females (AOR = 2.30, 95% CI 1.50-3.51), in patients with depression symptoms (AOR = 8.27, 95% CI = 4.97-13.74) and anxiety symptoms (AOR = 1.45, 95% CI = 0.84-2.50).

Conclusion

This study reported that the prevalence of PTSD, depression, and anxiety were high. Patients having depressive symptoms, anxiety symptoms, and being female are more at risk of developing PTSD. There is a need to integrate screening for common mental disorders in the context of humanitarian emergencies and its adapted integration of psychosocial interventions.

Risk factors for posttraumatic stress disorder in trauma patients from bullfighting-related events in Spain

BACKGROUND

Unintentional Trauma injuries are one of the leading causes of posttraumatic stress disorder development. However, screening for this condition is not typically included in routine medical care. Research on posttraumatic stress disorder after unintentional injuries sustained during entertainment activities involving risk, has been scarce. This study aimed to analyze the proportion of posttraumatic stress disorder and its risk factors in patients with trauma injuries sustained during bullfighting-related events in Spain.

METHODS

Two hundred and seventy-four patients were evaluated to determine the presence of posttraumatic stress disorder at least one month after the injury. Data about sociodemographic variables, injury circumstances, characteristics of the injury, and treatments were collected by the surgery team on-site or collected during the follow-up assessment. Diagnosis of posttraumatic stress disorder was made by a trained clinician using a structured clinical interview based on DSM criteria.

RESULTS

The estimated proportion of was 25.18 % (95 % CI: 20.18 %, 30.18 %). Residing in areas with a bullfighting tradition, female gender, referral to a medical center, hospitalization, events involving fighting bulls, and having been injured by the crowd were significant predictors.

LIMITATIONS

The short-term follow-up and the inability to evaluate some predictors of interest, including the body site of the injury, the presence of disfigurement, and comorbid anxiety and depression, were noted.

CONCLUSION

Posttraumatic stress disorder could have a high prevalence in individuals injured in these types of events, especially in women, those who are not familiar with the situation, and those who require medical attention. These results highlight the need for routine screening for posttraumatic stress disorder in individuals with trauma injuries for early symptom management.

Psilocybin analog 4-OH-DiPT enhances fear extinction and GABAergic inhibition of principal neurons in the basolateral amygdala

Psychedelics such as psilocybin show great promise for the treatment of depression and PTSD, but their long duration of action poses practical limitations for patient access. 4-OH-DiPT is a fast-acting and shorter-lasting derivative of psilocybin. Here we characterized the pharmacological profile of 4-OH-DiPT and examined its impact on fear extinction learning as well as a potential mechanism of action. First, we profiled 4-OH-DiPT at all 12 human 5-HT GPCRs. 4-OH-DiPT showed strongest agonist activity at all three 5-HT2A/2B/2C receptors with near full agonist activity at 5-HT2A. Notably, 4-OH-DiPT had comparable activity at mouse and human 5-HT2A/2B/2C receptors. In a fear extinction paradigm, 4-OH-DiPT significantly reduced freezing responses to conditioned cues in a dose-dependent manner with a greater potency in female mice than male mice. Female mice that received 4-OH-DiPT before extinction training had reduced avoidance behaviors several days later in the light dark box, elevated plus maze and novelty-suppressed feeding test compared to controls, while male mice did not show significant differences. 4-OH-DiPT produced robust increases in spontaneous inhibitory postsynaptic currents (sIPSCs) in basolateral amygdala (BLA) principal neurons and action potential firing in BLA interneurons in a 5-HT2A-dependent manner. RNAscope demonstrates that Htr2a mRNA is expressed predominantly in BLA GABA interneurons, Htr2c mRNA is expressed in both GABA interneurons and principal neurons, while Htr2b mRNA is absent in the BLA. Our findings suggest that 4-OH-DiPT activates BLA interneurons via the 5-HT2A receptor to enhance GABAergic inhibition of BLA principal neurons, which provides a potential mechanism for suppressing learned fear.

Correlates of post-traumatic stress disorder among adult residents of conflict-affected communities in Cross River State, Nigeria: a cross-sectional study

BACKGROUND

Conflict-affected communities in Nigeria experience a range of problems. These experiences have been associated with different types of mental disorders, most notably, post-traumatic stress disorder (PTSD).

AIM

This study sought to assess PTSD and its associated factors among adults in conflict-affected communities in Odukpani Local Government Area (LGA), Cross River State, Nigeria.

METHODS

A cross-sectional study was conducted using non-probability and probability sampling techniques. The sample size for this study was 486 conflict-affected adults. The symptoms of PTSD were assessed using the Harvard Trauma Questionnaire and a semistructured questionnaire was employed to collect data on sociodemographic and trauma-related characteristics. Data were analysed using descriptive statistics, χ2 and multivariable logistic regression.

RESULTS

The prevalence of PTSD in conflict-affected communities in Odukpani LGA, Cross River State, Nigeria was 73.9%. The multivariate analysis revealed that higher educational attainment (AOR 5.66; p<0.001; 95% CI 2.37 to 13.54), family size >4 (AOR 1.72; p=0.03; 95% CI 1.06 to 2.77), discrimination because of present status (AOR 1.96; p=0.03; 95% CI 1.26 to 3.06) and family history of mental illnesses (AOR 2.08; p=0.002; 95% CI 1.31 to 3.31) showed statistically significant relationships with PTSD in the study population.

CONCLUSION

A multisectoral approach for creating and routinely arranging mental health interventions and aid programmes aimed at improving social outcomes such as employment, living conditions and social networks for conflict-affected communities is recommended.

Improving access to evidence-based interventions for trauma-exposed adults in low- and middle-income countries

In low- and middle-income countries (LMICs), the mental health consequences of trauma exposure pose a substantial personal, societal, and economic burden. Yet, the significant need for evidence-based mental health treatment remains largely unmet. To unlock the potential for mental health care for trauma survivors in lower-resource contexts, it is critical to map treatment barriers and identify strategies to improve access to evidence-based, culturally appropriate, and scalable interventions. This review, based on an International Society for Traumatic Stress (ISTSS) briefing paper, describes the treatment gap facing adults with traumatic stress in LMICs and identifies the barriers that contribute to this gap. We then highlight strategies for enhancing access to effective treatments for these populations, including task-sharing, the use of culturally adapted and multiproblem interventions, and digital tools to scale access to appropriate care. Finally, we offer recommendations for policymakers, researchers, and service providers to guide an agenda for action to close the treatment gap for trauma survivors in LMICs.

Is lifetime abuse forgivable in old age?

Old age is characterized by reflection and a retrospective examination of the multiple meanings of various life experiences, including lifelong abuse. Forgiveness is found to have a salutary effect, especially for older adults. To understand the place and role of forgiveness in the reflective process during aging, we performed a secondary analysis of in-depth, semi-structured interviews (N = 78) with older women survivors of abuse. Inductive thematic analysis was based on concepts developed deductively from the literature review. The findings include three main themes: (1) The dimensions of forgiving: The victim as subject; (2) Being forgiven: Between lost forgiveness and hope; and (3) Self-forgiveness and the aging self. Despite the known salutary effect of forgiveness, we must consider that this is not a universally desirable process. We included the dimension of forgiveness in the study of abuse throughout the older person's life course and identified further complexities in addition to the "forgiveness"/"unforgiveness."

Resilience and Disaster: Flexible Adaptation in the Face of Uncertain Threat

Disasters cause sweeping damage, hardship, and loss of life. In this article, we first consider the dominant psychological approach to disasters and its narrow focus on psychopathology (e.g., posttraumatic stress disorder). We then review research on a broader approach that has identified heterogeneous, highly replicable trajectories of outcome, the most common being stable mental health or resilience. We review trajectory research for different types of disasters, including the COVID-19 pandemic. Next, we consider correlates of the resilience trajectory and note their paradoxically limited ability to predict future resilient outcomes. Research using machine learning algorithms improved prediction but has not yet illuminated the mechanism behind resilient adaptation. To that end, we propose a more direct psychological explanation for resilience based on research on the motivational and mechanistic components of regulatory flexibility. Finally, we consider how future research might leverage new computational approaches to better capture regulatory flexibility in real time.

Support interventions to promote health and wellbeing among women with health-related consequences following traumatic experiences linked to armed conflicts and forced migration: a scoping review

BACKGROUND

Women exposed to armed conflicts and forced migration face significant health-related risks and consequences. Consequently, there is a need to identify and develop effective interventions that provide tailored support for them. The aim of this scoping review was to examine research evaluating support interventions promoting the health and well-being among women with traumatic experiences linked to armed conflict and/or forced migration.

METHODS

A scoping review of empirical studies evaluating non-pharmacologic/non-surgical interventions promoting health and well-being among adult women with traumatic experiences linked to armed, torture, and/or forced migration, identified through systematic searches in February 2022 within five databases (AMED, CINAHL, Cochrane Library, PsycINFO, and PubMed). Methodological characteristics and results were extracted and analyzed with narrative analysis using tabulations, descriptive statistics, text-based summaries, and thematization.

RESULTS

Assessment of 16 748 records resulted in 13 included reports. The methodological approaches were quantitative (n = 9), qualitative (n = 2), and mixed methods (n = 2), with most reports being feasibility/pilot studies (n = 5) and/or randomized controlled trials (n = 4). The most common recruitment strategy was non-probability sampling (n = 8). Most interventions were conducted in North America (n = 4), Asia (n = 3) or Middle East (n = 3). Thirteen intra-intervention techniques and five categories of components utilized within the interventions were identified, the most common being skill building (n = 12). Ten developed the interventions through theoretical frameworks or manuals/therapy, while five developed interventions through public or stakeholder involvement. Eleven studies evaluated outcomes related to psychological health, disorders, or distress. A large proportion of the investigated outcomes showed post-exposure improvements and improvements when compared with controls. Qualitative findings highlighted improved mental and physical health, empowerment and stigma reduction, and enhanced knowledge.

CONCLUSION

Few studies have developed and evaluated tailored support interventions for this population, containing a range of components and intra-intervention techniques. No clear focus was identified regarding outcome measures, and most studies used non-probability sampling. Few developed interventions through public contribution in collaboration with women. While limited studies show promising effects on women's mental health, more empirical intervention research that closely corresponds to women's needs are needed.

Common genetic variation impacts stress response in the brain

To explain why individuals exposed to identical stressors experience divergent clinical outcomes, we determine how molecular encoding of stress modifies genetic risk for brain disorders. Analysis of post-mortem brain (n=304) revealed 8557 stress-interactive expression quantitative trait loci (eQTLs) that dysregulate expression of 915 eGenes in response to stress, and lie in stress-related transcription factor binding sites. Response to stress is robust across experimental paradigms: up to 50% of stress-interactive eGenes validate in glucocorticoid treated hiPSC-derived neurons (n=39 donors). Stress-interactive eGenes show brain region- and cell type-specificity, and, in post-mortem brain, implicate glial and endothelial mechanisms. Stress dysregulates long-term expression of disorder risk genes in a genotype-dependent manner; stress-interactive transcriptomic imputation uncovered 139 novel genes conferring brain disorder risk only in the context of traumatic stress. Molecular stress-encoding explains individualized responses to traumatic stress; incorporating trauma into genomic studies of brain disorders is likely to improve diagnosis, prognosis, and drug discovery.

Integrative attitudes of Ukrainian war refugees in two neighboring European countries (Poland and Hungary) in connection with posttraumatic stress symptoms and social support

Since February 24th, 2022, millions of Ukrainians have sought refuge in other, mainly European countries. Hungary, after Poland, is the second largest host of Ukrainian refugees. Only a portion of them are asylum seekers (~11.0% in Poland and ~ 1.1% in Hungary). The aim of the study is to compare the integrative acculturation attitudes between the war refugees residing in the two European countries. The comparison takes into account both the suffering of posttraumatic stress symptoms and social support. It is the first comparative study of this kind pertaining to the Ukrainian refugees in European countries. The data were obtained by a survey method using the modified CAPI (Computer Assisted Personal Interview) technique. The data analyzed were collected between November 21st and December 20th, 2022 from 728 adult Ukrainian individuals who crossed the borders of Poland and Hungary after February 24th, 2022. The research results show that refugees in Poland perceive significantly more social support and show stronger integrative attitudes than refugees in Hungary. The two samples do not differ regarding the presence of posttraumatic stress. The integrative attitudes proved not to be linked to gender and age, but linked to the host country. Besides social support and the host country, posttraumatic stress also proved to be a significant predictor of integrative attitudes.

Post-traumatic stress disorder symptoms and quality of life among older patients with cancer during the COVID-19 pandemic

INTRODUCTION

The Coronavirus (COVID-19) pandemic and its associated health restrictions have harmed the population psychologically. We aimed to compare the post-traumatic stress disorder (PTSD) symptoms and Quality of Life (QoL) in older French patients with cancer to the younger ones.

MATERIALS AND METHODS

This longitudinal multicenter study named COVIPACT began in April 2020 during the first French lockdown and has included 579 outpatients receiving treatment for a solid or hematological malignancy. Data were collected every three months, namely at the first release period (M3), at the second lockdown (M6), at the second release period (M9), and finally at the last curfew period (M12) in France. Standardized validated self-questionnaires were used to assess PTSD symptoms (using the Event Scale-Revised self-questionnaire), insomnia (through the Insomnia Severity Index questionnaire), QoL (using the Functional Assessment of Cancer Therapy - General questionnaire), and cognitive complaints (through the Functional Assessment of Cancer Therapy - Cognition questionnaire). Student (or Wilcoxon) tests and Chi-squared tests were used for continuous or discrete variables, respectively. We conducted linear mixed model to study the change during follow-up.

RESULTS

Out of 579 included patients, 157 (27%) were ≥ 70 years old at baseline, of whom 104 participated in the longitudinal study. At baseline, older patients reported fewer PTSD symptoms (17% versus 23%, p = .06), insomnia (17% versus 27%, p = .02), and cognitive complaint (3% versus 16%, p < .01) than younger patients. QoL at baseline was similar between age subgroups. We observed no significant difference in the trajectory of PTSD symptoms, insomnia, or emotional well-being between both groups during the follow-up. Cognitive complaints were lower at baseline in older patients but steadily increased during the follow-up and reached the same level as younger patients at one year.

DISCUSSION

One in five older patients reported PTSD symptoms, evolving similarly to younger patients during the first year of the COVID-19 pandemic. While cognitive complaints tend to recover in a bell-shaped curve at one year in younger patients, the trend is increasing in older ones. Screening for PTSD symptoms and late cognitive impairment should be given special attention in older patients.

Trauma Matters: Integrating Genetic and Environmental Components of PTSD

Trauma is ubiquitous, but only a subset of those who experience trauma will develop posttraumatic stress disorder (PTSD). In this review, it is argued that to determine who is at risk of developing PTSD, it is critical to examine the genetic etiology of the disorder and individual trauma profiles of those who are susceptible. First, the state of current PTSD genetic research is described, with a particular focus on studies that present evidence for trauma type specificity, or for differential genetic etiology according to gender or race. Next, approaches that leverage non-traditional phenotyping approaches are reviewed to identify PTSD-associated variants and biology, and the relative advantages and limitations inherent in these studies are reflected on. Finally, it is discussed how trauma might influence the heritability of PTSD, through type, risk factors, genetics, and associations with PTSD symptomology.

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.

Historical and regional particularities in the prevalence of traumatic events and posttraumatic stress disorder in East and West Germany

BACKGROUND

Epidemiological research on the prevalence of traumatic events and PTSD has shown that there are significant differences between countries, due to their different history and socialization processes. In the case of Germany, this is particularly relevant. Germany was divided into two states from 1949 to 1990. This study examines the prevalence of traumatic events and PTSD in the formerly divided East and West Germany.

METHODS

For the prevalence of traumatic events, we used data from four representative surveys (years 2005, 2007, 2008, and 2016) with a total of N = 9,200 respondents. For the analyses of PTSD prevalence, we used data from three representative surveys (years 2005, 2007, 2008) with a total of N = 6676 respondents. We compared different birth cohorts, persons living in the former West vs. East Germany, and the application of different diagnostic criteria using a chi-square test.

RESULTS

The overall one-month prevalence rate for PTSD was 3.4% (3.0% for men and 3.8% for women). We found significant differences in the occurrence of traumatic events between genders, different age cohorts as well as between people who live in East and West Germany. Significant differences in the prevalence of PTSD can only be observed for different age cohorts. Most of the age effects are due to traumatic events related to World War II (WWII). Prevalence rates for PTSD were higher when the diagnostic criterions of the DSM-V were applied compared to the criterions of the DSM-IV.

CONCLUSIONS

Our data suggests that socio-political factors may need to be considered when accounting for differences in occurrence rates of traumatic events, but not for prevalence rates of PTSD, between East and West Germany. People who have experienced WW II have a higher risk of suffering from PTSD. Future epidemiological trauma research should take historical and regional peculiarities of countries into account.

Perinatal experiences of Ukrainian women at the beginning of the war

OBJECTIVE

Pregnancy and childbirth are related to the experience of distress at their core. However, this distress is significantly increased under war conditions. The study aims to examine the perinatal experience of women during the war in Ukraine.

METHODS

12 Ukrainian women who were pregnant and lived in Kyiv or the suburbs of Kyiv from February to May 2022 took part in the study. In-depth interviews were conducted online in the form of semi-structured interviews, and the thematic analysis technique was used.

RESULTS

The perinatal experiences of women during the war in Ukraine were divided into 2 basic groups: negative perinatal experiences and positive perinatal experiences during the war. The negative perinatal experiences were grouped into three main themes: 1) negative emotions experienced in association with war, 2) dissatisfaction with medical support during the war, 3) suffering associated with separation from a husband and relatives. The positive perinatal experiences include 6 main themes: 1) the joy of returning or/and staying home, 2) satisfaction with medical support during the war, 3) coping with stress during the war, 4) family relationships and support during the war, 5) positive attitudes towards the child (or unborn child), 6) patriotic sentiments.

CONCLUSION

The study revealed negative and positive aspects of the perinatal experience of Ukrainian women during the war. Providing access to medical advice, facilitating uncertainty reduction, and communication between women and their families contribute to positive perinatal experiences of pregnant women and new mothers during the war.

The impact of the war in Ukraine on the perinatal period: Perinatal mental health for refugee women (pmh-rw) protocol

Background

The aim of the Perinatal Mental Health for Refugee Women (PMH-RW) Project is to investigate the impact of the war on perinatal mental health: anxiety, post-traumatic stress, depression, and birth trauma symptoms. It will also evaluate the factors that serve as protective elements for the development of these potential diagnoses (such as personality traits, social support, sociodemographic characteristics, and access to medical/mental health services).

Method

An international observational cohort study with baseline data is being assessed in Ukraine (for internal refugees) and several European Countries (for external refugees). The study includes as participants both pregnant women and those who have recently given birth (with babies up to 1 year old). The assessment includes measures on depression (EPDS), anxiety (GAD-7), experiences during birth (City Birth Questionnaire), post-traumatic stress symptoms [Impact of events scale—revised (PTSD-R)], Personality (10-Item Personality Inventory-TIPI), and a questionnaire for socio-demographic data which also such social support.

Conclusion

This study will provide needed information for determining the impact of the Ukrainian Crisis on perinatal mental health by studying potential risk and protective factors. The data collected will be used to inform policymakers with useful information that can be used in the development of plans to protect and promote the mental health of the perinatal refugees impacted by this event. Also, it is our hope that data collected from this study will serve to plant the seeds for further research regarding the impact of the crisis in Ukraine on the offspring and to analyze how these events are affecting further generations.

The Mental Health Costs of Armed Conflicts-A Review of Systematic Reviews Conducted on Refugees, Asylum-Seekers and People Living in War Zones

AIMS

Armed conflicts produce a wide series of distressing consequences, including death, all of which impact negatively on the lives of survivors. This paper focuses specifically on the mental health consequences of war on adults and child/adolescent refugees or those living in war zones through a review of all systematic reviews and/or meta-analyses published from 2005 up until the current time.

RESULTS

Fifteen systematic reviews and/or meta-analyses conducted in adult populations, and seven relating to children and adolescents, were selected for the purpose of this review. Prevalence rates of anxiety, depression and post-traumatic stress disorder (PTSD) were two- to three-fold higher amongst people exposed to armed conflict compared to those who had not been exposed, with women and children being the most vulnerable to the outcome of armed conflicts. A series of war-related, migratory and post-migratory stressors contribute to short- and long-term mental health issues in the internally displaced, asylum seekers and refugees.

CONCLUSION

It should be a required social responsibility for all psychiatrists and psychiatric associations to commit to raising awareness amongst political decision-makers as to the mental health consequences caused by armed conflicts, as part of their duty of care for people experiencing the consequences of war.

Sex-specific role of hippocampal NMDA-Erk-mTOR signaling in fear extinction of adolescent mice

Adolescence is a key phase of development for perturbations in fear extinction, with inability to adequately manage fear a potent factor for developing psychiatric disorders in adulthood. However, while behavioral correlates of adolescent fear regulation are established to a degree, molecular mediators of extinction learning in adolescence remain largely unknown. In this study, we observed fear acquisition and fear extinction (across 4 and 7 days) of adolescent and adult mice of both sexes and investigated how hippocampal levels of different plasticity markers relate to extinction learning. While fear was acquired evenly in males and females of both ages, fear extinction was found to be impaired in adolescent males. We also observed lower levels of GluA1, GLUN2A and GLUN2B subunits in male adolescents following fear acquisition, with an increase in their expression, as well as the activity of Erk-mTOR pathway over subsequent extinction sessions, which was paralleled with improved extinction learning. On the other hand, we detected no changes in plasticity-related proteins after fear acquisition in females, with alterations in GluA1, GluA4 and GLUN2B levels across fear extinction sessions. Additionally, we did not discern any pattern regarding the Erk-mTOR activity in female mice associated with their extinction performance. Overall, our research identifies sex-specific synaptic properties in the hippocampus that underlie developmentally regulated differences in fear extinction learning. We also point out hippocampal NMDA-Erk-mTOR signaling as the driving force behind successful fear extinction in male adolescents, highlighting this pathway as a potential therapeutic target for fear-related disorders in the adolescent population.

Post-traumatic stress disorder and associated factors among adult war survivors in Northwest Ethiopia: Community-based, cross-sectional study

Background

A person may endure or witness a traumatic incident, such as being exposed to war, and, as a result, develop post-traumatic stress disorder (PTSD). There is a lack of information about post-traumatic stress disorder in low and middle-income countries such as Ethiopia. However, armed conflict, abuse of human rights, and violence motivated by race are becoming more commonplace. This study aimed to assess the prevalence of PTSD and associated factors among war survivors in Nefas Meewcha Town, South Gondar Zone, Ethiopia, 2022.

Methods

A community based cross-sectional study was carried out. 812 study participants were chosen using a multi-stage sampling process. A face-to-face interview used a post-traumatic stress disorder checklist (PCL-5) to evaluate PTSD. The association between PTSD and other demographic and psychosocial characteristics was investigated using bivariate and multivariable binary logistic regression analysis. A P-value of 0.05 was declared as statistical significance.

Result

The prevalence of PTSD in this study was 40.8% with a 95% CI of 36.2 to 46.7. The likelihood of developing PTSD was significantly associated with the fallowing factors. A close family member killed or seriously injured (AOR = 4.53, 95% CI = 3.25-6.46), being female (AOR = 1.98, 95% CI = 1.3-3.0), moderate (AOR = 3.51, 95% CI = 2.52-4.68) and high perceived stress (AOR = 5.23, 95% CI = 3.47-8.26), depression symptoms (AOR = 4.92, 95% CI = 3.57-6.86), anxiety disorder symptoms (AOR = 5.24, 95% CI = 3.72-7.63), a chronic medical illness (AOR = 3.51, 95% CI = 2.52-5.41), physical assault (AOR = 2.12, 95% CI = 1.05-3.72) and being in a war fighting situation (AOR = 1.41, 95% CI = 1.21-3.14).

Conclusion

This study reported that the prevalence of PTSD was high. Being female, having a previous history of chronic medical illness, depressive symptoms, anxiety symptoms, history of a family member or friend was injured or killed, poor social support, high perceived stress, physical assault, and being in a war fighting situation were statistically associated with PTSD. Hence, regular patient assessment by mental health organizations for those with a history of trauma and facilitation of ways to support such residents is highly recommended.

Correlates and prevalence of post-traumatic stress disorders in the São Paulo metropolitan area, Brazil

BACKGROUND

Post-traumatic stress disorder (PTSD) is a debilitating condition, which generates an extensive burden. We aimed to investigate in a huge metropolitan area, the prevalence of traumatic experiences, the development of PTSD, and its predictors.

METHODS

Traumatic experiences and PTSD were assessed in 5037 adult individuals of the general population. Cross-tabulations method assessed the prevalence of traumatic events and PTSD. Logistic regression models investigated predictors of lifetime and 12-month odds of PTSD and the conditional probability of developing PTSD for specific traumas.

RESULTS

Lifetime and 12-month diagnoses of PTSD were found in 3.2% and 1.6% of the sample. 'Witnessing anyone being injured or killed, or unexpectedly seeing a dead body' (35,7%) and 'being mugged or threatened with a weapon' (34.0%) were the two most reported traumas. The commonest events before PTSD onset were 'sudden unexpected death of a loved one' (34.0%), 'interpersonal violence' (31.0%), and 'threats to the physical integrity of others' (25.0%). Experiences related to "interpersonal violence" presented the highest conditional probability for PTSD (range 2.2-21.2%). Being 'sexually assaulted or molested' (21.2% total; 22.3% women; 0.0% men) and being 'raped' (18.8% total; 18.4% women; 20.1% men) were the two experiences with the highest odds for PTSD. While being female was a predictor of less exposure to any event (OR = 0.69), females were more prone to develop lifetime PTSD after exposure to an event (OR = 2.38).

CONCLUSION

Traumatic events are frequent in the general population and a small group of traumatic events accounts for most cases of subsequent PTSD.

The mental health of forcibly displaced couples

Most current research investigating traumatic stress is focused on its effects at the individual level, utilizing the implicit assumption that trauma-related disorders are mutually independent within families and communities. However, there is reason to assume that trauma-related symptoms within couples are influenced by each partner's risk factors and symptoms. Using the actor-partner interdependence model, this study aimed to test whether symptoms of posttraumatic stress disorder (PTSD) and depression were predicted by participants' partner's exposure to traumatic events over and above the influence of the participant's own experiences. For this purpose, we interviewed 687 heterosexual, married Iraqi and Syrian couples in Iraq's Kurdistan region who had been forcefully displaced. We assessed symptoms of PTSD and depression using locally validated scales. Nearly all participants (98.8%) reported exposure to at least one traumatic event, with husbands reporting exposure to a higher number of traumatic events than wives, d = 0.48, p < .001. More than half of the participants met the criteria for a probable PTSD (61.1%) or major depressive disorder diagnosis (60.4%). Within couples, significant actor effects of experienced trauma exposure on personal PTSD and depressive symptoms were observed for both husbands and wives. Further, there were significant partner effects of wives' traumatic experiences on husbands' PTSD and depressive symptoms as well as of husbands' traumatic experiences on wives' PTSD and depressive symptoms. The findings argue for the interdependence of trauma-related symptoms within dyads in a dual-trauma context, suggesting the presence of intracouple transmission of trauma-related symptoms.

Tinnitus and Traumatic Memory

Events linked to post-traumatic stress disorder (PTSD) influence psychological and physical health through the generation, exacerbation, and maintenance of symptoms such as anxiety, hyperarousal, and avoidance. Depending upon circumstance, traumatic events may also contribute to the onset of tinnitus, post-traumatic headache, and memory problems. PTSD should be considered a psychological injury, andwhile tinnitus is a symptom, its onset and sound quality may be connected in memory to the injury, thereby evincingthe capacity to exacerbate the trauma’s effects. The myriad attributes, psychological and mechanistic, shared by tinnitus and PTSD offer tinnitus investigators the opportunity to draw from the rich and long-practiced strategies implemented for trauma counseling. Mechanisms and interventions understood through the lens of traumatic exposures may inform the clinical management of tinnitus disorder, and future studies may assess the effect of PTSD intervention on co-occurring conditions. This brief summary considered literature from both the hearing and trauma disciplines, with the goal of reviewing mechanisms shared between tinnitus and PTSD, as well as clinical reports supporting mutual reinforcement of both their symptoms and the effects of therapeutic approaches.

The Involvement of Past Traumatic Life Events in the Development of Postpartum PTSD after Cesarean Delivery

Background: Although childbirth is considered a natural process, a high percentage of postpartum women consider it traumatic. Any previous traumatic event in a woman’s life can be revived through a traumatic birth experience, especially after a complicated vaginal delivery or cesarean delivery. The purpose of this study was to clarify the relationship between previous traumatic life events and posttraumatic stress disorder (PTSD) in postpartum women after cesarean section and which specific events exerted the greatest influence. Methods: A sample of 469 women who had undergone cesarean sections at a Greek university hospital consented to participate in this prospective study. Data from a medical/demographic questionnaire, life events checklist, perinatal stressor criterion A, and posttraumatic stress checklist were used to evaluate past traumatic life events and diagnose postpartum posttraumatic stress. Results: Out of 469 women, 25.97% had PTSD and 11.5% a PTSD profile, while 2.7% had PTSD and 2.7% a PTSD profile. Also, it appeared that only specific direct exposure to a traumatic event and/or witnessing one were predictors of postpartum PTSD. Conclusions: This survey identified specific traumatic life events, psychiatric history, stressor perinatal criterion A, preterm birth, and emergency cesarean section as risk factors for the development of PTSD or a PTSD profile in women after cesarean delivery.

Prevalence of Posttraumatic Stress Disorder Symptoms Following Traumatic Spinal Cord Injury: A Systematic Review and Meta-analysis

BACKGROUND

Limited evidence is currently available on the prevalence of posttraumatic stress disorder (PTSD) following traumatic spinal cord injury (SCI). This systematic review and meta-analysis aims to assess the prevalence and geographic distribution of PTSD symptoms after SCI.

METHODS

After a search in the MEDLINE, Embase, Scopus, and Web of Science databases, two reviewers independently summarized relevant studies published through 20 October 2021. Observational studies were included. The studies were eligible if they assessed PTSD symptoms using standard self-report or clinician-based instruments. Data and results were reported using the overall prevalence and the odds ratio (OR), with 95% confidence intervals (CIs).

RESULTS

24 articles (5646 patients) met the inclusion criteria. The prevalence of PTSD symptoms ranged from 6.33% (95% CI, 2.73-13.97) to 61.76% (95% CI, 52.07-70.61). Pooled analysis demonstrated that the overall prevalence of PTSD symptoms in SCI patients was significantly higher in developing countries (41.64%; 95% CI, 31.11-52.55) than in developed countries (19.35%; 95% CI, 14.66-24.51) (OR = 1.24; 95% CI, 1.08-1.42; p = .003). The highest prevalence of PTSD symptoms was reported in South Africa (56.25%; 95% CI, 47.01-65.08), followed by Sri Lanka (45.71%; 95% CI, 30.47-61.81), and Greece (43.55%; 95% CI, 31.94-55.91). By contrast, Norway (6.33%; 95% CI, 2.73-13.97), Switzerland/Germany (8.65%; 95% CI, 4.8-13.42), and Denmark (10.71%; 95% CI, 6.89-16.30) were found to have the lowest prevalence of PTSD symptoms after SCI.

CONCLUSION

Many traumatic SCI patients suffer from PTSD symptoms, and their prevalence seems to be higher in developing countries than in developed countries. These findings underscore the need to consider the psychological aspects of traumatic SCI.

War trauma and PTSD in Ukraine's civilian population: comparing urban-dwelling to internally displaced persons

INTRODUCTION

War in Ukraine started in March 2014 when Russia annexed Crimea and continues today in the Donbass region of Eastern Ukraine. Over 1.5 million people in these regions have been displaced from their homes. We conducted this study 36 months after the conflict began and interviewed civilians residing in Ukraine.

PURPOSE

This study examines the prevalence of exposure to war trauma, rates of PTSD by symptom clusters, and whether socio-demographic factors are associated with positive scores for PTSD among civilian urban-dwelling and internally displaced persons in Ukraine during the ongoing conflict in its Donbass region.

METHODS

Face-to-face interviews were conducted using a multi-stage random sample of the general population in two large cities (Kharkiv and Lviv) in Ukraine (n = 1247) and a purposive sample of internally displaced persons (n = 300), half living in each city. Exposure to trauma, symptom clusters for Posttraumatic Stress Disorder (PTSD), and overall PTSD were assessed.

RESULTS

We found widespread direct exposure to conflict-related traumatic events (65%) among internally displaced people (IDPs) compared to a sizable minority (23%) of urban-dwelling people (UDPs). We found elevated prevalence of PTSD symptoms that were also uniformly spread within several socio-demographic factors. There were, however, significant differences in PTSD between (1) IDPs compared to UDPs and (2) those UDPs with Ukrainian compared to Russian ethnic identity, the former of each pair showing increased likelihoods of positive PTSD scores.

CONCLUSIONS

Ukraine's adult civilians, enduring the prolonged engagement in war with Russia and Russian separatists, have elevated rates of PTSD. Moreover, those who have been displaced by the ongoing conflict (IDPs) have significantly higher levels of PTSD compared to UDPs.

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.

Evaluation of post-traumatic stress disorder (PTSD) and related comorbidities in clinical studies

Patients with traumatic brain injury (TBI) of varying severities are experiencing adverse outcomes during and after rehabilitation. Besides depression and anxiety, post-traumatic stress disorder (PTSD) is highly encountered in civilian and military populations. As more prospective and retrospective studies - focused on evaluating new or old psychological therapies in inpatient, outpatient, or controlled environments, targeting patients with PTSD with or without a history of TBI - are carried out, researchers are employing various scales to measure PTSD as well as other psychiatric diagnoses or cognitive impairments that might appear following TBI. We aimed to explore the literature published between January 2010 and October 2021 by querying three databases. Our preliminary results showed that several scales - such as the Clinician-Administered PTSD Scale (CAPS), the Posttraumatic Stress Disorder Checklist Military Version (PCL-M) as well as Specific Version (PCL-S), and Civilian Version (PCL-C) - have been frequently used for PTSD diagnosis and symptom severity. However, heterogeneity in the scales used when assessing and evaluating additional psychiatric comorbidities and cognitive impairments are due to the study aim and therapeutic approaches. Therefore, conducting an intervention focusing on post-TBI PTSD patients requires increased attention to patients' medical history in capturing multiple cognitive impairments and affected neuropsychological processes when designing the study and including validated instruments for measuring primary and secondary neuropsychological outcomes.

Mental health consequences of armed conflicts in adults: an overview

Armed conflicts (AC) in the world are still active and lead to the growth of violence, with a possible impact on mental health (MH).

Relationship between Socio-Demographic Factors and Posttraumatic Stress Disorder: A Cross Sectional Study among Civilian Participants' Hostilities in Ukraine

Background: Even though there is an extensive body of literature on posttraumatic stress disorder (PTSD) in individuals who have experienced armed conflict, there are still many grey areas, especially in relation to civilian participants in hostilities. This article evaluates how socio-demographic factors and the interactions between them have influenced PTSD among civilians involved in the recent war in Ukraine. Methods: This cross-sectional study included a convenience sample of 314 adults, 74 women, and 235 men. The mean age was 34.08 years. We used the Posttraumatic Stress Disorder (PTSD) Checklist–Civilian Version (PCL-C). Results: Our findings show that predictors of posttraumatic stress are loss of a loved one, place of residence, gender, continuation of education, and health insurance. We demonstrated that PTSD produced by the loss of a loved one as a result of war is determined by participation in the education system, whatever the level of education. The literature emphasises the importance of social support, e.g., from the family. We demonstrated that having children is associated with a risk of more severe PTSD, causing serious mental strain among participants of hostilities. We discovered that material security lowers PTSD, but only among people who have no children. Conclusions: PTSD is the result of not only the violence and damage caused by war but also of other stressful circumstances associated with the social and financial conditions of life. Further research needs to focus on identifying modifiable risk factors and protective factors that could be embraced by intervention strategies. Our findings can inform the goals behind therapeutic support for civilian participants of hostilities, and implications for social work. Social work professionals are encouraged to engage in direct questioning and to maintain a supportive and safe environment for participants in hostilities, e.g., in the area of education. Trauma-affected people need to be given opportunities to build up their strengths and increase their psychological resources towards well-being. Social security (health insurance, savings, material security) should be taken into account when working with people affected by PTSD.

Post-traumatic stress disorder psychological interventions in sub-Saharan Africa: protocol for a systematic review of the literature

INTRODUCTION

Untreated post-traumatic stress disorder (PTSD) results in considerable morbidity and higher risk of mortality. However, little is being done to treat PTSD in sub-Saharan Africa (SSA) settings where rates of PTSD are likely to be elevated due to mass exposure of the population to traumatic events. This systematic review aims to summarise available evidence on the efficacy of psychological therapies for PTSD in SSA.

METHODS AND ANALYSIS

A systematic search of the literature will be conducted in four electronic databases: PubMed, PsychInfo, EMBASE and Cochrane Register of Controlled Trials using keywords and synonyms related to 'PTSD', 'psychological therapies' and 'SSA'. Studies will be included if they were conducted in SSA and used a randomised controlled trial design. Two researchers will screen the studies for eligibility to be included, and data on intervention types, population, comorbidities, comparison group intervention and PTSD outcomes will be extracted from those included. Risk of bias will be assessed using Cochrane risk-of-bias tool for randomised trials (version 2). Narrative synthesis of data will be conducted and pooled effect estimates calculated.

ETHICS AND DISSEMINATION

Ethical approval is not required as this is a protocol of a systematic review of available data. Findings will be disseminated to the scientific community through peer-reviewed publications and presentation at conferences.

Hallucinogenic drugs and their potential for treating fear-related disorders: Through the lens of fear extinction

Fear-related disorders, mainly phobias and post-traumatic stress disorder, are highly prevalent, debilitating disorders that pose a significant public health problem. They are characterized by aberrant processing of aversive experiences and dysregulated fear extinction, leading to excessive expression of fear and diminished quality of life. The gold standard for treating fear-related disorders is extinction-based exposure therapy (ET), shown to be ineffective for up to 35% of subjects. Moreover, ET combined with traditional pharmacological treatments for fear-related disorders, such as selective serotonin reuptake inhibitors, offers no further advantage to patients. This prompted the search for ways to improve ET outcomes, with current research focused on pharmacological agents that can augment ET by strengthening fear extinction learning. Hallucinogenic drugs promote reprocessing of fear-imbued memories and induce positive mood and openness, relieving anxiety and enabling the necessary emotional engagement during psychotherapeutic interventions. Mechanistically, hallucinogens induce dynamic structural and functional neuroplastic changes across the fear extinction circuitry and temper amygdala's hyperreactivity to threat-related stimuli, effectively mitigating one of the hallmarks of fear-related disorders. This paper provides the first comprehensive review of hallucinogens' potential to alleviate symptoms of fear-related disorders by focusing on their effects on fear extinction and the underlying molecular mechanisms. We overview both preclinical and clinical studies and emphasize the advantages of hallucinogenic drugs over current first-line treatments. We highlight 3,4-methylenedioxymethamphetamine and ketamine as the most effective therapeutics for fear-related disorders and discuss the potential molecular mechanisms responsible for their potency with implications for improving hallucinogen-assisted psychotherapy.

Meaning-Making Predicts Forgiveness as an Indicator of Posttraumatic Growth and Resilience in a Culturally Diverse Sample

Trauma is a growing public health concern as global crises increase. Trauma can result in significant adverse psychological outcomes such as posttraumatic stress disorder (PTSD). Past research indicates that forgiveness may buffer the adverse psychological effects of trauma. We hypothesized that restoring individual and collective sense of meaning promotes forgiveness toward self and others and enables posttraumatic growth (PTG). Established PTG models posit that meaning can be found in surviving a traumatic event. We propose that PTG manifests as forgiveness in the face of both natural and humanmade disasters. Data were collected from individuals ( N = 3,534) in 11 countries from diverse global regions that have experienced collective traumas. Our study examined the predictive nature of meaning in life and PTSD symptoms on forgiveness. Hierarchical regression analysis indicated that trauma and meaning significantly predicted forgiveness, with a larger effect for humanmade disasters. Results indicated that presence of meaning, but not search for meaning, plays a role in PTG as measured by the ability to forgive after experiencing trauma, thus demonstrating its possible centrality to the healing process. Interventions and community-based programs that foster meaning-making following trauma may be part of an effective multicultural approach for enhancing community-wide PTG and resilience following disasters.

Post-traumatic stress disorder and associated factors among people who experienced traumatic events in Dessie town, Ethiopia, 2022: A community based study

BACKGROUND

Posttraumatic stress disorder (PTSD) may develop as a serious long-term consequence of traumatic experiences, even many years after trauma exposure. Dessie town residents have experienced prolonged armed conflict due to inter-communal conflict in 2021. Those people are exposed to different kinds of trauma, and violence, making them more prone to psychological disorders. Despite the highest number of people affected due to conflict and its negative impact on mental health, post-traumatic stress disorders among people are overlooked in Ethiopia. This study aimed to assess the prevalence and associated factors of post-traumatic stress disorder among people who experienced traumatic events in Dessie town, Ethiopia, 2022.

MATERIALS AND METHODS

Community based cross-sectional study was conducted on June 8-July 7, 2022, by using a multi-stage cluster sampling with a total sample of 785. Pretested, structured questionnaires and face-to-face interviews were used for data collection. PTSD was assessed by the Post-traumatic stress disorder Checklist for DSM-5 (PCL-5). Data was entered using Epi-data version 3.1 and, then exported to SPSS version 26 for analysis. The association between outcome and independent variables was analyzed with bi-variable and multivariable logistic regression. P-values less than 0.05 was considered statistically significant.

RESULT

The prevalence of PTSD among Dessie town residents was found to be 19.4% (95% CI, 16.7, 22.0). In multivariable analysis, being females (AOR = 1.63, 95% CI 1.10-2.44), previous history of mental illness (AOR = 3.14, 95% CI 1.14-7.06) depressive symptoms (AOR = 3.12, 95% CI 1.92-5.07), witnessing a serious physical injury of a family member or friend (AOR = 2.82, 95% CI 1.18-6.70) and high perceived life threats (AOR = 5.73, 95% CI 3.05-10.78) were found to be significant predictors of PTSD.

CONCLUSION

The prevalence of PTSD among Dessie town residents was found to be huge. Being female, having a previous history of mental illness, depressive symptoms, witnessing a serious physical injury of a family member or friend, and high perceived life threats were variables that are independent predictors of PSTD. People who have experienced such a severe traumatic event require psychosocial support to aid in their recovery from the terrible experiences.

Prevalence and prediction of PTSD and depression in mothers of children surviving a motor vehicle crash

Introduction: Few studies have examined the psychopathological consequences for parents of children who were survivors of a motor vehicle crash (MVC). This study assessed the impact of dissociation and peritraumatic distress on the severity of PTSD and post-traumatic major depressive episode (MDE) symptoms in mothers during the first years after the MVC and the role that cortisol response might play in this association. Methods: 125 mothers were included. Peritraumatic distress and dissociation were assessed. Morning salivary cortisol was tested at the baseline. Participants were assessed for a probable diagnosis of PTSD and MDE at 5 weeks, 6 months and 12 months. Results: At 5 weeks, 12 (13.6%) mothers exhibited probable PTSD. During the first year, the PCL score was higher when the (i) Peritraumatic Distress Inventory (PDI) score increased and (ii) the Peritraumatic Dissociation Experience Questionnaire (PDEQ) score increased. Cortisol levels were lower when the PDI score increased. Conclusion: This is the first study to assess the mothers of MVC survivors for one year following the trauma. We confirm that peritraumatic responses are useful for predicting the severity of PTSD symptoms. These results could encourage the implementation of follow-up programmes not only for survivors but also for their mothers. HIGHLIGHTS Mothers of children involved in motor vehicle accident are at risk for developing PTSD.Peritraumatic responses (distress and dissociation) are associated to the severity of PTSD symptoms.Low salivary cortisol levels were associated with high peritraumatic distress.

Impact of war and forced displacement on children's mental health-multilevel, needs-oriented, and trauma-informed approaches

The infliction of war and military aggression upon children must be considered a violation of their basic human rights and can have a persistent impact on their physical and mental health and well-being, with long-term consequences for their development. Given the recent events in Ukraine with millions on the flight, this scoping policy editorial aims to help guide mental health support for young victims of war through an overview of the direct and indirect burden of war on child mental health. We highlight multilevel, need-oriented, and trauma-informed approaches to regaining and sustaining outer and inner security after exposure to the trauma of war. The impact of war on children is tremendous and pervasive, with multiple implications, including immediate stress-responses, increased risk for specific mental disorders, distress from forced separation from parents, and fear for personal and family's safety. Thus, the experiences that children have to endure during and as consequence of war are in harsh contrast to their developmental needs and their right to grow up in a physically and emotionally safe and predictable environment. Mental health and psychosocial interventions for war-affected children should be multileveled, specifically targeted towards the child's needs, trauma-informed, and strength- and resilience-oriented. Immediate supportive interventions should focus on providing basic physical and emotional resources and care to children to help them regain both external safety and inner security. Screening and assessment of the child's mental health burden and resources are indicated to inform targeted interventions. A growing body of research demonstrates the efficacy and effectiveness of evidence-based interventions, from lower-threshold and short-term group-based interventions to individualized evidence-based psychotherapy. Obviously, supporting children also entails enabling and supporting parents in the care for their children, as well as providing post-migration infrastructures and social environments that foster mental health. Health systems in Europe should undertake a concerted effort to meet the increased mental health needs of refugee children directly exposed and traumatized by the recent war in Ukraine as well as to those indirectly affected by these events. The current crisis necessitates political action and collective engagement, together with guidelines by mental health professionals on how to reduce harm in children either directly or indirectly exposed to war and its consequences.

3,4-Methylenedioxy methamphetamine, synthetic cathinones and psychedelics: From recreational to novel psychotherapeutic drugs

The utility of classical drugs used to treat psychiatric disorders (e.g., antidepressants, anxiolytics) is often limited by issues of lack of efficacy, delayed onset of action or side effects. Psychoactive substances have a long history of being used as tools to alter consciousness and as a gateway to approach the unknown and the divinities. These substances were initially obtained from plants and animals and more recently by chemical synthesis, and its consumption evolved toward a more recreational use, leading to drug abuse-related disorders, trafficking, and subsequent banning by the authorities. However, these substances, by modulation of certain neurochemical pathways, have been proven to have a beneficial effect on some psychiatric disorders. This evidence obtained under medically controlled conditions and often associated with psychotherapy, makes these substances an alternative to conventional medicines, to which in many cases the patient does not respond properly. Such disorders include post-traumatic stress disease and treatment-resistant depression, for which classical drugs such as MDMA, ketamine, psilocybin and LSD, among others, have already been clinically tested, reporting successful outcomes. The irruption of new psychoactive substances (NPS), especially during the last decade and despite their recreational and illicit uses, has enlarged the library of substances with potential utility on these disorders. In fact, many of them were synthetized with therapeutic purposes and were withdrawn for concrete reasons (e.g., adverse effects, improper pharmacological profile). In this review we focus on the basis, existing evidence and possible use of synthetic cathinones and psychedelics (specially tryptamines) for the treatment of mental illnesses and the properties that should be found in NPS to obtain new therapeutic compounds.

About Six in Ten Survivors of the November 2020 Maikadra Massacre Suffer from Posttraumatic Stress Disorder, Northwest Ethiopia

BACKGROUND

Post-traumatic stress disorder (PTSD) is characterized by recurrent, involuntary, and intrusive distressing memories of a traumatic event and dissociative reactions. Little is known about post-traumatic stress disorder in low and middle income countries such as Ethiopia where armed conflict, human rights violations, and ethnic-based violence are becoming everyday occurrences.

OBJECTIVE

This study aimed to assess the prevalence of post-traumatic stress disorder and associated factors among residents of Maikadra, North West Ethiopia.

METHODS

A community-based cross-sectional study was employed in April 2021. A multi-stage cluster sampling technique was employed to select the study participants. A post-traumatic stress disorder checklist (PCL-5) was used to assess post-traumatic stress disorder through a face-to-face interview. Bivariate and multi-variable binary logistic regression analyses were carried out to examine the association between posttraumatic stress disorder and several demographic and psychosocial variables. Statistical significance was declared at a P-value <0.05.

RESULTS

A total of 610 participants were interviewed with a response rate of 98.8%. The prevalence of PTSD in this study was 59.8% with a 95% CI of 55.7-63.9. Female sex (AOR=1.93, 95% CI=1.64-3.24), having a close family member killed or seriously injured (AOR=1.96, 95% CI=1.1-3.48), having moderate (AOR=3.35, 95% CI=1.98-5.68) and high perceived threat to life (AOR=3.66, 95% CI=1.85-6.95), having depression (AOR=1.67, 95% CI=1.13-2.47) and anxiety disorder (AOR=1.85, 95% CI=1.21-2.83), and being directly exposed to the event (AOR=3.27, 95% CI=1.09-9.83) were significantly associated with post-traumatic stress disorder.

CONCLUSION

The majority of the residents of Maikadra town where the November 2020 massacre took place experienced posttraumatic stress disorder. Female sex, having a family member or a friend murdered or seriously injured, having depression and anxiety disorders and being directly exposed to the trauma were found to be significant predictors of post-traumatic stress disorder. People who have been exposed to such an intense traumatic event need psychosocial support to help them recover from the horrible experiences.

Sexual assault as a public health problem and other developments in psychotraumatology

A recent scandal in the Netherlands painfully underscored that sexual harassment and abuse are unfortunately still happening around the world, even after decades of advocacy on this issue and five years of #MeToo. To make progress in prevention and treatment we argue that we should address sexual violence from a public health perspective. Fruthermore, looking back on the past year, the COVID-19 pandemic was the dominant and potentially traumatic stressor affecting large populations around the world. Another big topic was that of the impact of climate change, we are only beginning to realize its impact on stress across the globe. The European Journal of Psychotraumatology (EJPT), with its increasing global readership and scientific and social impact, is focusing on the traumatic stress aspects of these and many other events. Relatedly, neurobiological aspects are an important and growing focus of the journal in that they help us better understand the mechanisms behind the development of trauma-related disorders and their treatment. In this editorial, we present recent trends, new Open Science developments, journal metrics, the plans and themes for next year and the ESTSS EJPT award winners for best paper of 2021.

HIGHLIGHTS

Next years' research focus should be on sexual violence from a public health lens, climate change, and neurobiologal aspects of trauma-related disorders. The European Journal of Psychotraumatology (EJPT) calls or papers on these issues.

New Metabolic, Digestive, and Oxidative Stress-Related Manifestations Associated with Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) represents a pressing and generally invalidating syndrome that is triggered by a terrifying or stressful experience, relying on recurrently reliving the traumatic event feelings associated to it, which is subsequently linked to ongoing activations of stress-related neurobiological pathways and is often associated with neurodegeneration. In this paper, we examine what lies beneath this disorder, reviewing evidence that connects PTSD with a wide array of mechanisms and its intertwined pathways that can lead to the decompensation of different pathologies, such as cardiovascular disease, gastrointestinal ailments, autoimmune disorders, and endocrine diseases. Also, the significance of the oxidative stress in this frame of reference is debated. Thus, knowing and identifying the main features of the distressing experience, the circumstances around it, as well as the neuropsychological and emotional characteristics of people prone to develop PTSD after going through disturbing incidents can offer an opportunity to anticipate the development of potential destructive consequences in several psychological dimensions: cognitive, affective, relational, behavioral, and somatic. We can also observe more closely the intricate connections of the disorder to other pathologies and their underlying mechanisms such as inflammation, oxidative stress, bacterial overgrowth syndrome, irritable bowel syndrome, metabolic disorders, oxytocin, and cortisol in order to understand it better and to optimize the course of treatment and its management. The complex foundation PTSD possesses is supported by the existing clinical, preclinical, and experimental data encompassed in the current review. Different biological systems and processes such as the hypothalamic-pituitary-adrenal axis, sympathetic nervous system, oxidative stress, inflammation, and microbiome suffer modifications and changes when it comes to PTSD; that is why targeted therapies exert tremendous alleviations of symptoms in patients diagnosed with this disorder. Therefore, this implies that PTSD is not restricted to the psychiatric domain and should be viewed as a systemic condition.

Bruton's tyrosine kinase drives neuroinflammation and anxiogenic behavior in mouse models of stress

BACKGROUND

Current therapies targeting several neurotransmitter systems are only able to partially mitigate the symptoms of stress- and trauma-related disorder. Stress and trauma-related disorders lead to a prominent inflammatory response in humans, and in pre-clinical models. However, mechanisms underlying the induction of neuroinflammatory response in PTSD and anxiety disorders are not clearly understood. The present study investigated the mechanism underlying the activation of proinflammatory NLRP3 inflammasome and IL1β in mouse models of stress.

METHODS

We used two mouse models of stress, i.e., mice subjected to physical restraint stress with brief underwater submersion, and predator odor stress. Mice were injected with MCC950, a small molecule specific inhibitor of NLRP3 activation. To pharmacologically inhibit BTK, a specific inhibitor ibrutinib was used. To validate the observation from ibrutinib studies, a separate group of mice was injected with another BTK-specific inhibitor LFM-A13. Seven days after the induction of stress, mice were examined for anxious behavior using open field test (OFT), light-dark test (LDT), and elevated plus maze test (EPM). Following the behavior tests, hippocampus and amygdale were extracted and analyzed for various components of NLRP3-caspase 1-IL1β pathway. Plasma and peripheral blood mononuclear cells were also used to assess the induction of NLRP3-Caspase 1-IL-1β pathway in stressed mice.

RESULTS

Using two different pre-clinical models of stress, we demonstrate heightened anxious behavior in female mice as compared to their male counterparts. Stressed animals exhibited upregulation of proinflammatory IL1β, IL-6, Caspase 1 activity and NLRP3 inflammasome activation in brain, which were significantly higher in female mice. Pharmacological inhibition of NLRP3 inflammasome activation led to anxiolysis as well as attenuated neuroinflammatory response. Further, we observed induction of activated Bruton's tyrosine kinase (BTK), an upstream positive-regulator of NLRP3 inflammasome activation, in hippocampus and amygdala of stressed mice. Next, we conducted proof-of-concept pharmacological BTK inhibitor studies with ibrutinib and LFM-A13. In both sets of experiments, we found BTK inhibition led to anxiolysis and attenuated neuroinflammation, as indicated by significant reduction of NLRP3 inflammasome and proinflammatory IL-1β in hippocampus and amygdala. Analysis of plasma and peripheral blood mononuclear cells indicated peripheral induction of NLRP3-caspase 1-IL1β pathway in stressed mice.

CONCLUSION

Our study identified BTK as a key upstream regulator of neuroinflammation, which drives anxiogenic behavior in mouse model of stress. Further, we demonstrated the sexually divergent activation of BTK, providing a clue to heightened neuroinflammation and anxiogenic response to stress in females as compared to their male counterparts. Our data from the pharmacological inhibition studies suggest BTK as a novel target for the development of potential clinical treatment of PTSD and anxiety disorders. Induction of pBTK and NLRP3 in peripheral blood mononuclear cells of stressed mice suggest the potential effect of stress on systemic inflammation.

Dog training alleviates PTSD symptomatology by emotional and attentional regulation

Background

Post-Traumatic Stress Disorder (PTSD) symptoms include re-experiencing, avoidance, hyperarousal, and cognitive deficits, reflecting both emotional and cognitive dysregulation. In recent years, non-pharmacological approaches and specifically animal-assisted therapy have been shown to be beneficial for a variety of disorders such as Attention-Deficit/Hyperactivity Disorder, Autism Spectrum Disorder, and PTSD. However, little is mentioned in the literature about the reciprocal effects of the animal-human interaction.

Objective

To evaluate the effects of a one-year dog training programme on PTSD symptomatology in youngsters with PTSD and on dogs' behaviour.

Methods

Fifty-three adolescents, previously exposed to interpersonal trauma, were clinically diagnosed with PTSD and assigned to a dog-training programme group (n = 30) and a control group (n = 23) that engaged in other training programmes (e.g. cooking, hairstyling, etc.). Both groups were evaluated at baseline and following 12-months by The Clinician-Administered PTSD Scale for DSM-5 in Children and Adolescents (CAPS-CA-5) and Beck-Depression Inventory (BDI). Additionally, we physiologically measured both emotional and attention dysregulation.

Results

Post-12-months training, a significant alleviation of PTSD symptomatology accompanied by lower depression severity was observed in the dog-training group, compared with a insignificant recovery in the control group. Furthermore, improved emotional and attentional regulation was observed in the dog-training group. Measuring the dogs' behaviour revealed increased anxiety and decreased selective attention performance, which was inversely correlated with the beneficial effects observed in the dog-training programme group.

Conclusions

Our findings emphasize the role of emotional and attentional regulations on the dog-handler interface, as evidence-based support for the beneficial effects of the dog-training programme, as either a non-pharmacological intervention or as complementary to anti-depressants treatment of PTSD. Though pharmacological treatments increase the patients' well-being by treating certain PTSD symptoms, our suggested dog-training programme seems to influence the PTSD diagnostic status, thus may be implemented in civilians and veterans with PTSD.

Social support, resilience, and mental health in a low-intensity warfare context: the effects of siege on university students in Gaza

BACKGROUND

Gaza has long been enduring a quasi-total siege that significantly undermines quality of life in the region. Gazan youth are particularly affected by the ongoing economic recession, a disrupted environment, and health and food insecurity. These critical circumstances are worsened by the ongoing conflict between Palestine and Israel, which is a cause of death and destruction.

AIMS

This cross-sectional study investigated the effects of living under protracted siege conditions on mental distress, resilience, and social support among a sample of Palestinian university students living on the Gaza Strip.

METHODS

Five hundred fifty Palestinian university students were recruited at four universities in Gaza. They completed a battery of instruments, including the Gaza Siege Checklist, Depression, Anxiety and Stress Scale (DASS), Resilience Scale (RS), and Berlin Social Support Scales (BSSS). We used structural equation modelling (SEM) to test a conceptual model of social support and resilience as protective factors against the impact on mental distress of living under siege.

RESULTS

Our findings indicate that living under siege has direct adverse effects, leading to increased mental distress in the form of anxiety, depression, and acute stress. Enduring siege conditions compromises resilience and sources of social support, thereby increasing subjects' risk of developing psychological distress.

Global burden of post-traumatic stress disorder and major depression in countries affected by war between 1989 and 2019: a systematic review and meta-analysis

Objective

Extensive research has demonstrated high prevalences of post-traumatic stress disorder (PTSD) and major depression (MD) in war-surviving populations. However, absolute estimates are lacking, which may additionally inform policy making, research and healthcare. We aimed at estimating the absolute global prevalence and disease burden of adult survivors of recent wars (1989–2019) affected by PTSD and/or MD.

Methods

We conducted a systematic literature search and meta-analysis of interview-based epidemiological surveys assessing the prevalence of PTSD and/or MD in representative samples from countries with a recent war history (1989–2019). Drawing on the war definition and geo-referenced data of the Uppsala Conflict Database Programme and population estimates of the United Nations for 2019, we extrapolated the meta-analytic results to absolute global numbers of affected people. Drawing on disability-adjusted life years (DALYs) data of the Global Burden of Diseases Study 2019, we further calculated the PTSD-associated and MD-associated DALYs.

Results

Twenty-two surveys (N=15 420) for PTSD, 13 surveys for MD (N=9836) and six surveys on the comorbidity of PTSD and MD (N=1131) were included. Random effects meta-analyses yielded point prevalences of 26.51% for PTSD and 23.31% for MD. Of those affected by PTSD, 55.26% presented with comorbid MD. Prevalence rates were not significantly associated with war intensity and length, time since war, response rate or survey quality. The extrapolation yielded 316 million adult war-survivors globally who suffered from PTSD and/or MD in 2019. War-survivors were almost exclusively living in low/middle-income countries (LMICs) and carried a burden of 3 105 387 and 4 083 950 DALYs associated with PTSD and MD, respectively.

Conclusions

Since LMICs lack sufficient funding and qualified professionals to provide evidence-based psychological treatments for such large numbers of affected people, alternative and scalable strategies using existing resources in primary care and communities are required. Research is required to assist upscaling.
