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.

Background: Coronavirus disease 2019 (COVID-19), like any other pandemic, has imposed an unprecedented threat to physical and mental health to all nations, worldwide. There is no enough evidence in the literature in this area. The present study has been done to explore the organization of psychiatric services in Bosnia and Herzegovina (BH) to meet mental health needs of BH citizens during the particular restrictive measures caused by COVID-19 pandemic. Materials and Methods: This online survey has been done for BH psychiatric institutions. Data were collected from psychiatric institutions in the mental health network of BH. A total of 38 complete responses have been received. Results: Of 38 study participants, three were the departments of psychiatry in university clinical centers, two were psychiatric hospitals, four were psychiatric wards in general hospitals, 27 were community mental health centers, and two were institutes for alcoholism and drug addiction. During the pandemic, all services functioned on a reduced scale, adhering to measures to protect and self-protect both staff and service users. Protective equipment was provided to staff in some institutions in a timely and complete manner and in some in an untimely and incomplete manner. Consultative psychiatric examinations were mainly performed through telephone and online, where it exists as a standard patient monitoring protocol. The application of long-acting antipsychotics was continuous with adherence to restricted and protective measures. In opiate addiction replacement therapy services, substitution therapy was provided for a longer period to reduce frequent contacts between staff and patients. Individual and group psychotherapy continued in reduced number using online technologies, although this type of service was not administratively regulated. An initiative has been given to regulate and administratively recognize telepsychiatry by health insurance funds in the country. A number of psychological problems associated with restrictive measures and fear of illness have been reported by patients as well as by the professionals in mental healthcare teams. There were no COVID-19-positive patients seeking help from institutions that responded to the questionnaire. In one center, infected people with COVID-19 from abroad sought help through the phone. Only one involuntary hospitalization was reported. The involvement of mental health professionals in the work of crisis headquarters during the design of the COVID-19 pandemic control measures varies from satisfactory to insufficient. Education of staff, patients, and citizens was regular with direct instructions through meetings, press, and electronic media. Conclusions: During the COVID-19 pandemic in BH, all psychiatric services functioned on a reduced scale, adhering to measures to protect and self-protect staff and service users. All patients who asked for help have been adequately treated in direct inpatient or outpatient mental healthcare or online, despite telepsychiatric services not being recognized in health system in BH. There were neither infected patients nor staff with COVID-19 in the psychiatric institutions who responded in this research. A large-scale, multicenter study needs to be performed to get a broader picture and to guide us for future better service planning and delivery.

Background: People with mental and behavioural disorders have low satisfaction of quality of life, due to numerous symptoms, as well as poor interpersonal relations, communications skills, low tolerance on frustration. Aim: The aim of this paper was to evaluate whether there has been an improvement in satisfaction with the quality of life after the application of group therapy Methods: The study included 100 patients who attended group therapy, for a period of 6-12 weeks. The instruments used at the beginning and at the end of the treatment were Outcome Questionnaire-45 which measured symptoms distress, interpersonal relations, and social roles, and MANSA questionnaire that measured satisfaction with the quality of life. Results: In total sample (N = 100) there was approximately equal number of women and men (51% vs. 49%). The average age of the subjects was 48.11 ± 7.91. Majority of respondents had depressive disorder (45%). Measuring the mean values obtained on the OQ-45 questionnaire, it was found that after the application of group therapy a significant reduction of the level of dysfunction was achieved. A statistically significant difference was found in the areas of satisfaction with physical and mental health, and the overall score of the MANSA questionnaire. Conclusion: Results show that patients reported lower symptoms distress and higher satisfaction with quality of life after attending group therapy, better interpersonal relations, lower risk of suicidal behaviour and substance abuse. Group therapy is successful intervention which helps patients improve quality of life.

STUDY OBJECTIVES Sleep problems are common, serving as both a predictor and symptom of posttraumatic stress disorder (PTSD), with these bidirectional relationships well established in the literature. While both sleep phenotypes and PTSD are moderately heritable, there has been a paucity of investigation into potential genetic overlap between sleep and PTSD. Here, we estimate genetic correlations between multiple sleep phenotypes (including insomnia symptoms, sleep duration, daytime sleepiness, and chronotype) and PTSD, using results from the largest genome-wide association study (GWAS) to date of PTSD, as well as publicly available GWAS results for sleep phenotypes within UK Biobank data (23 variations, encompassing four main phenotypes). METHODS Genetic correlations were estimated utilizing linkage disequilibrium score regression (LDSC), an approach that uses GWAS summary statistics to compute genetic correlations across traits, and Mendelian randomization (MR) analyses were conducted to follow up on significant correlations. RESULTS Significant, moderate genetic correlations were found between insomnia symptoms (rg range 0.36-0.49), oversleeping (rg range 0.32-0.44), undersleeping (rg range 0.48-0.49), and PTSD. In contrast, there were mixed results for continuous sleep duration and daytime sleepiness phenotypes, and chronotype was not correlated with PTSD. MR analyses did not provide evidence for casual effects of sleep phenotypes on PTSD. CONCLUSION Sleep phenotypes, particularly insomnia symptoms and extremes of sleep duration, have shared genetic etiology with PTSD, but causal relationships were not identified. This highlights the importance of further investigation into the overlapping influences on these phenotypes as sample sizes increase and new methods to investigate directionality and causality become available.

The risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5–20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men. Along with other novel genes and non-coding RNAs, a Parkinson’s disease gene involved in dopamine regulation, PARK2, is associated with PTSD. Finally, we demonstrate that polygenic risk for PTSD is significantly predictive of re-experiencing symptoms in the Million Veteran Program dataset, although specific loci did not replicate. These results demonstrate the role of genetic variation in the biology of risk for PTSD and highlight the necessity of conducting sex-stratified analyses and expanding GWAS beyond European ancestry populations. Post-traumatic stress disorder (PTSD) is a common mental health problem. Here, the authors report a GWAS from the Psychiatric Genomics Consortium in which they identify two risk loci in European ancestry and one locus in African ancestry individuals and find that PTSD is genetically correlated with several other psychiatric traits.

Background: Posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) are known psychological outcomes that can co-occur in the aftermath of a traumatic event. However, it is less clear how these outcomes interact – particularly for female survivors of conflict-related sexual violence (CRSV) – and to what extent intermediary factors play a role in this relationship. Methods: In a sample of 192 war survivors from Bosnia & Herzegovina (n = 104 experienced CRSV, n = 88 did not), a structural equation model (LISREL 8.8) tested CRSV as a traumatic event, 'positive reinterpretation' (as a strategy of approach coping) and 'behavioural disengagement' (as a strategy of avoidance coping), and PTSD and PTG as psychosocial outcomes. A difference in the mechanisms by which PTG and PTSD interact in the two subgroups was hypothesised, given the differences in the nature of the trauma they experienced. Results: Through multiple indirect relationships, results showed that CRSV survivors respond to their trauma with both PTSD and PTG, suggesting a dual PTSDPTG mechanism. As for coping strategies, positive reinterpretation predicted greater PTG, and behavioural disengagement predicted greater PTSD. In the sample of nonsexual violence survivors, positive reinterpretation also remained a significant predictor of PTG. Conclusions: Positive reinterpretation as a coping strategy appears to be a stable characteristic that independently predicts PTG, irrespective of trauma type. Mental health professionals should take into account this mechanism when addressing the needs of CRSV survivors, but also war survivors more generally. Reframing traumatic events and post-trauma sequalae during treatment could lead to PTG and enhance recovery.

BACKGROUND The aim of this study is to investigate the association of gene variations of the monoamine oxidase A (MAOA) and the serotonin transporter solute carrier family 6 member 4 (SLC6A4) gene with posttraumatic stress disorder (PTSD) severity and coping strategies in patients with war related PTSD. SUBJECTS AND METHODS The study included 747 individuals who had experienced war trauma in the South Eastern Europe conflicts between 1991 and 1999. Genotyping of the MAOA VNTR and SLC6A4 tandem repeat polymorphism in combination with rs25531 was done in 719 participants: 232 females and 487 males. Among them, 369 have had current or lifetime PTSD and 350 have had no PTSD symptoms. For psychometric approach we used the Clinician Administrated PTSD Scale (CAPS), the Brief Symptom Inventory (BSI), the adapted Hoffman-Lazarus Coping scale and a basic socio-demographic data questionnaire. RESULTS There were no significant intergroup (PTSD versus non PTSD) differences in the genotype distribution of MAOA and SLC6A4 gene polymorphisms. The primary finding of our study was that the MAOA short allele (MAOA-S) was nominally significantly associated with the severity of PTSD symptoms in the total subgroup of participants with lifetime PTSD; males for symptoms of hyperarrousal and females with symptoms of re-experience and hyperarousal. In our research the male subsample with current PTSD and MAOA-S genotype had nominally significantly higher scores for some positive coping strategies compared to those carrying the long allele genotype (MAOA-L). There was no significant association between the severity of PTSD symptoms, BSI phenotype, coping scores and the SLC6A4 genotype. CONCLUSION The present results support the notion that MAOA VNTR gene variation modulates development and recovery of posttraumatic stress disorder in a war traumatised population, but did not support a connection between SLC6A4 gene variations and war related PTSD.

BackgroundConflict-related sexual violence (CRSV) was committed on a large scale against women across Bosnia and Herzegovina (BiH) during the 1990’s war, and research has shown both negative and positive psychosocial outcomes following such acts of interpersonal violence. We aim to determine the capacity for posttraumatic growth (PTG) among a population of women who experienced CRSV, and to what extent it is impacted by factors such as coping and optimism.MethodsThis study sought to examine the relationship between PTG (posttraumatic growth inventory), symptoms of posttraumatic stress disorder (PTSD; Harvard Trauma Questionnaire) and dispositional factors such as coping (COPE) and optimism (Life-Orientation Test-Revised) in a sample of n = 104 women. We first conducted bivariate correlations and then hierarchical linear regression analyses, and hypothesized that approach coping strategies and optimism will act to enhance PTG.ResultsFindings showed that the average total score for PTG in this study was 58.94 (SD = 23.01), and current PTSD symptomatology above a threshold of > 2.5 was detected in 92.3% (n = 96) participants (mean score 3.18, SD = .45). Bivariate correlations showed that higher levels of PTG were associated with greater optimism, greater approach coping strategies positive reinterpretation and planning, and lower avoidance strategies behavioural disengagement and substance use. When entered into a regression model, only positive reinterpretation and behavioural disengagement remained, the R-square of the total set of predictors was 0.16, thus explaining 16% of PTG total score.ConclusionTwo types of coping (namely capacity of both greater positive reinterpretation and lower behavioural disengagement) most strongly predicted growth after trauma in this sample of CRSV survivors from BiH. These dimensions of coping confirm the role of coping strategies in the development of PTG. Further research would be useful in corroborating these findings in other post-conflict settings, and delving further into the possibility of a dual mechanism of growth and distress after CRSV.

BACKGROUND Posttraumatic stress disorder (PTSD) is a disorder that occurs in some people who have experienced a severe traumatic event. Several genetic studies suggest that gene encoding proteins of catechol-O-methyl-transferase (COMT) may be relevant for the pathogenesis of PTSD. Some researchers suggested that the elevation of interleukin-6 (IL6) correlates with major depression and PTSD. The aim of this study was to investigate whether the single nucleotide polymorphisms COMT rs4680 (Val158Met) and IL6 rs1800795 are associated with PTSD and contribute to the severity of PTSD symptoms. SUBJECTS AND METHODS This study comprised 747 participants that experienced war between 1991 and 1999 in the South Eastern Europe conflicts. COMT rs4680 (Val158Met) and IL6 rs1800795 genotypes were determined in 719 participants (369 with and 350 without PTSD). The Mini International Neuropsychiatric Interview (M.I.N.I.), the Clinician Administrated PTSD Scale (CAPS) questionnaire and the Brief Symptom Inventory (BSI) were used for data collection. RESULTS Regarding the COMT gene polymorphism, the results of the regression analyses for BSI total score were significant in the lifetime PTSD group in the dominant (P=0.031) and the additive allelic model (P=0.047). Regarding the IL6 gene, a significant difference was found for the recessive model predicting CAPS total score in the lifetime PTSD group (P=0.048), and indicated an association between the C allele and higher CAPS scores. n the allelic, genotypic and rezessive model, the results for BSI total score were significant in the lifetime PTSD group (P=0.033, P=0.028 and P=0.009), suggesting a correlation of the C allele with higher BSI scores. CONCLUSION Although our nominally significant results did not withstand correction for multiple tests they may support a relevance of the COMT (Val158Met) and IL6 rs1800795 polymorphism for aspects of PTSD in war traumatized individuals.

BACKGROUND Individuals who are exposed to traumatic events are at an increased risk of developing posttraumatic stress disorder (PTSD), a condition during which an individual's ability to function is impaired by emotional responses to memories of those events. The gene coding for neuropeptide Y (NPY) and the gene coding for brain-derived neurotrophic factor (BDNF) are among the number of candidate gene variants that have been identified as potential contributors to PTSD. The aim of this study was to investigate the association between NPY and BDNF and PTSD in individuals who experienced war-related trauma in the South Eastern Europe (SEE) conflicts (1991-1999). SUBJECTS AND METHODS This study included participants with current and remitted PTSD and healthy volunteers (N=719, 232 females, 487 males), who were recruited between 2013 and 2015 within the framework of the South Eastern Europe (SEE) - PTSD Study. Psychometric methods comprised the Mini International Neuropsychiatric Interview (M.I.N.I.), the Clinician Administered PTSD Scale (CAPS), and the Brief Symptom Inventory (BSI). DNA was isolated from whole blood and genotyped for NPY rs5574 via PCR - RFLP and NPY rs16147 and BDNF rs6265 using the KASP assay. RESULTS Tests for deviation from Hardy-Weinberg equilibrium showed no significant results. Analyses at the categorical level yielded no associations between the affected individuals and all three SNPs when compared to controls. Within lifetime PTSD patients, the major alleles of both NPY variants showed a nominally significant association with higher CAPS scores (p=0.007 and p=0.02, respectively). Also, the major allele of rs5574C>T was associated with higher BSI scores with a nominal significance among current PTSD patients (p=0.047). The results did not withstand a Bonferroni adjustment (α=0.002). CONCLUSION Nominally significant associations between NPY polymorphisms and PTSD susceptibility were found that did not withstand Bonferroni correction.

BACKGROUND Previous research showed inconsistent results concerning a possible association between solute carrier family 6 member 3 (SLC6A3) gene polymorphisms and dopamine symptoms of posttraumatic stress disorder (PTSD). Several studies also indicate that the myelin basic protein (MBP) gene is of importance in the etiology of several psychiatric disorders. The aim of this study was to investigate the relation of distinct SLC6A3 and MBP gene polymorphisms with PTSD and whether SLC6A3 and MBP genotypes contribute to PTSD symptom severity. SUBJECTS AND METHODS The study included 719 individuals who had experienced war trauma in the South Eastern Europe (SEE). Genotypes of variable number tandem repeat (VNTR) polymorphism within the SLC6A3 gene were assessed in 696 participants, and the single nucleotide polymorphism (SNP) rs12458282 located within the MBP gene region was genotyped in a total of 703 subjects. The Mini International Neuropsychiatric Interview, the Clinical Administrated PTSD Scale (CAPS) and Brief Symptom Inventory (BSI), were used for data collection. RESULTS No significant differences concerning the investigated SLC6A3 and MBP polymorphisms was identifiable between PTSD and non PTSD participants. Also we could not detect significant influence of these distinct SLC6A3 and MBP alleles on the severity of PTSD symptoms (CAPS) or BSI scores. However, the results of MBP rs12458282 within the patients with lifetime PTSD may point to a possible correlation of the major allele (T) with elevated CAPS scores. CONCLUSIONS Our results do not support an association of the analysed SLC6A3 and MBP gene polymorphisms with PTSD in war traumatized individuals. We found that there is a possibility for a correlation of the T allele rs12458282 within the MBP gene with higher CAPS scores in lifetime PTSD patients which would need to be tested in a sample providing more statistical power.

BACKGROUND Posttraumatic stress disorder (PTSD) is a complex stress related disorder, that follows a severe traumatic experience, characterized with an intense sense of terror, fear, and helplessness. The aim of this study is to identify associations of genetic variations within candidate genes DRD2 and DRD4 with various PTSD related phenotypes. PTSD lifetime and PTSD current subjects were analyzed separately, each of them were analyzed in a Case/Control design, as well as regarding BSI and CAPS within cases only. SUBJECTS AND METHODS 719 (487 male, 232 female) participants who had experienced war-related trauma between 1991 and 1999 in Bosnia and Hercegovina, Kosovo and Croatia were included in the study. Sociodemographic questionnaire, Clinician Administered PTSD Scale (CAPS) and the Brief Symptom Inventory (BSI) were used to collect clinical data. RESULTS The DRD2 rs1800497 variant and a variable number tandem repeat (VNTR) located in exon three of DRD4 were investigated for association with PTSD. In case control analyses we did not identify any significant associations. Within the PTSD current patients, we identified an association of DRD2 rs1800497 with BSI in the genotypic and the recessive model with the T allele as the risk allele. CONCLUSION Our findings suggest that rs1800497 of DRD2 gene is involved in pathogenesis of PTSD.
