Posttraumatic stress disorder (PTSD) genetics are characterized by lower discoverability than most other psychiatric disorders. The contribution to biological understanding from previous genetic studies has thus been limited. We performed a multi-ancestry meta-analysis of genome-wide association studies across 1,222,882 individuals of European ancestry (137,136 cases) and 58,051 admixed individuals with African and Native American ancestry (13,624 cases). We identified 95 genome-wide significant loci (80 novel). Convergent multi-omic approaches identified 43 potential causal genes, broadly classified as neurotransmitter and ion channel synaptic modulators (e.g., GRIA1, GRM8, CACNA1E), developmental, axon guidance, and transcription factors (e.g., FOXP2, EFNA5, DCC), synaptic structure and function genes (e.g., PCLO, NCAM1, PDE4B), and endocrine or immune regulators (e.g., ESR1, TRAF3, TANK). Additional top genes influence stress, immune, fear, and threat-related processes, previously hypothesized to underlie PTSD neurobiology. These findings strengthen our understanding of neurobiological systems relevant to PTSD pathophysiology, while also opening new areas for investigation.

Objective: During the COVID-19 pandemic, fear, anxiety, and depression have become global concerns among the wider public. This study aimed to examine the occurrence of fear, anxiety and depressive symptoms associated with COVID-19, to assess influencing factors that lead to the development of these mental health conditions and to examine any changes in the mental health patterns of the society since the initial study a year ago in Sarajevo, Bosnia and Herzegovina. Method : An anonymous online survey based on Fear of COVID-19 Scale (FCV-19S), General Anxiety Disorder-7 (GAD-7) and Patients Health Questionnaires (PHQs) was conducted in the general population of Sarajevo in Bosnia and Herzegovina. Results: From 1096 subjects, 81.3% were females, 33.8% had a high school degree, 56.4% were married, 53.4% were engaged in intellectual labor, 42.3% experienced fear, 72.9% had anxiety symptoms and 70.3% had depressive symptoms during the COVID-19 pandemic and their mean age was 35.84 ± 10.86. Half (50.1%) of the subjects were COVID-19 positive and 63.8% had COVID-19 symptoms when responding to the questionnaire. Experiencing COVID-19 related fear (OR = 1.972) and having moderate to severe depressive symptoms (OR = 9.514) were associated with the development of mild to severe anxiety symptoms during the COVID-19 pandemic, which were in turn associated with the development of moderate to severe depressive symptoms (OR = 10.203) and COVID-19 related fear (OR = 2.140), respectively, thus creating a potential circulus vicious. COVID-19 positive subjects (OR = 1.454) were also more likely to develop mild to severe anxiety symptoms during the COVID-19 pandemic. Conclusion: In conclusion, the prevalence of fear, anxiety symptoms and depressive symptoms rose dramatically since the beginning of the COVID-19 pandemic in Bosnia and Herzegovina. They were interconnected and were significantly associated with age, gender, marital status and COVID-19 status. Therefore, an urgent mental health intervention is needed for the prevention of mental health problems.

Introduction Resource-oriented interventions can be a low-cost option to improve care for patients with severe mental illnesses in low-resource settings. From 2018 to 2021 we conducted three randomized controlled trials testing resource-oriented interventions in Bosnia and Herzegovina (B&H), i.e. befriending through volunteers, multi-family groups, and improving patient-clinician meetings using the DIALOG+ intervention. All interventions were applied over 6 months and showed significant benefits for patients’ quality of life, social functioning, and symptom levels. In this study, we explore whether patient experiences point to common processes in these interventions. Methods In-depth semi-structured interviews were conducted with 15 patients from each intervention, resulting in a total sample of 45 patients. Patients were purposively selected at the end of the interventions including patients with different levels of engagement and different outcomes. Interviews explored the experiences of patients and were audio-recorded, transcribed, and analysed using the thematic analysis framework proposed by Braun and Clark. Results Three broad themes captured the overall experiences of patients receiving resource-oriented interventions: An increased confidence and agency in the treatment process; A new and unexpected experience in treatment; Concerns about the sustainability of the interventions. Conclusions The findings suggest that the three interventions – although focusing on different relationships of the patients – lead to similar beneficial experiences. In addition to being novel in the context of the mental health care system in B&H, they empower patients to take a more active and confident role in treatment. Whilst strengthening patients’ agency in their treatment may be seen as a value in itself, it may also help to achieve significantly improved treatment outcomes. This shows promise for the implementation of these interventions in other low-resource countries with similar settings.

Abstract Background Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are commonly reported co-occurring mental health consequences of psychological trauma exposure. The disorders have high genetic overlap. Trauma is a complex phenotype but research suggests that trauma sensitivity has a heritable basis. We investigated whether sensitivity to trauma in those with MDD reflects a similar genetic component in those with PTSD. Methods Genetic correlations between PTSD and MDD in individuals reporting trauma and MDD in individuals not reporting trauma were estimated, as well as with recurrent MDD and single-episode MDD, using genome-wide association study (GWAS) summary statistics. Genetic correlations were replicated using PTSD data from the Psychiatric Genomics Consortium and the Million Veteran Program. Polygenic risk scores were generated in UK Biobank participants who met the criteria for lifetime MDD (N = 29 471). We investigated whether genetic loading for PTSD was associated with reporting trauma in these individuals. Results Genetic loading for PTSD was significantly associated with reporting trauma in individuals with MDD [OR 1.04 (95% CI 1.01–1.07), Empirical-p = 0.02]. PTSD was significantly more genetically correlated with recurrent MDD than with MDD in individuals not reporting trauma (rg differences = ~0.2, p < 0.008). Participants who had experienced recurrent MDD reported significantly higher rates of trauma than participants who had experienced single-episode MDD (χ2 > 166, p < 0.001) Conclusions Our findings point towards the existence of genetic variants associated with trauma sensitivity that might be shared between PTSD and MDD, although replication with better powered GWAS is needed. Our findings corroborate previous research highlighting trauma exposure as a key risk factor for recurrent MDD.
