Background: Exposure to life-threatening events is common and everyone will most likely experience this type of trauma during their lifetime. Reactions to these events are highly heterogeneous and seems to be influenced by genes as well. Some individuals will develop posttraumatic stress disorder (PTSD), while others will not. In this study, our aim was to analyze the correlation between single nucleotide polymorphisms (SNPs) within the oxytocin receptor (OXTR) gene (rs53576 and rs2254298), the RAR-related orphan receptor A (RORA) gene (rs8042149) and the cannabinoid receptor 1 (CNR1) gene (rs1049353) and PTSD. All candidate genes have been previously associated with stress related disorders and the reaction to traumatic events.

Subjects And Methods: Participants (N=719) have been exposed to war-related trauma during the war in South-Eastern Europe (Bosnia and Herzegovina, Croatia and Kosovo). We correlated the presence and absence of current and lifetime PTSD as well as PTSD severity (Clinician Administered PTSD scale (CAPS)) and current psychopathology (Brief Symptom Inventory (BSI) score) with the mentioned SNPs. DNA was isolated from whole blood and genotyped for OXTR rs2254298 and rs53576 following previously published protocols, for RORA rs8042149 via PCR-RFLP and CNR1 rs1049353 via KASP.

Results: Nominally significant results were found for OXTR rs53576 in connection with the CAPS and BSI scores within lifetime PTSD patients. The additive allelic model indicated that G allele carriers achieved lower CAPS (p=0.0090) and BSI (p=0.0408) scores than participants carrying one or two copies of the A allele. These results did not withstand correction for multiple tests. No significant results were observed for OXTR rs2254298, RORA rs8042149 and CNR1 rs1049353 although the results for RORA showed a slight tendency that rs8042149 may influence the level of BSI scores in current PTSD patients.

Conclusions: This study points to a role of the OXTR gene in PTSD and the related psychopathology following war related trauma.

The psychological impact of disaster on first responders in the aftermath of Bahanaga train tragedy: A mixed methods approach.

Indian J Psychiatry

November 2024

Department of Psychiatry and Behavioural Sciences, Kalinga Institute of Medical Sciences (KIMS), KIIT University, Bhubaneswar, Odisha, India.

Background: First responders are at high risk for adverse mental health outcomes following trauma exposure during disaster response. This mixed methods study aimed to quantify psychological impacts and explore personal experiences among first responders after the Bahanaga train accident that killed 294 passengers in the month of June 2023.

Methods: For qualitative data, in-depth interviews (IDIs) were conducted, and quantitative data was collected using the PTSD checklist for DSM-5 (PCL-5), generalized anxiety disorder scale (GAD-7), and patient health questionnaire (PHQ-9) for symptoms of post-traumatic stress disorder (PTSD), depression, and anxiety.

Background And Aims: Evidence from high-income countries has linked duration and compliance with treatment for substance use disorders (SUDs) with reductions in substance use and improvements in mental health. Generalizing these findings to other regions like South America, where opioid and injection drug use is uncommon, is not straightforward. We examined if length of time in treatment and compliance with treatment reduced subsequent substance use and presence of psychiatric comorbidities.

Background: The increasing awareness of the emotional consequences of emergency cesarean deliveries (C-sections) highlights their substantial role in fostering postpartum post-traumatic stress disorder (PTSD). This systematic review and meta-analysis aim to evaluate the prevalence and determinants of PTSD following emergency C-sections, as well as the implications of these events on maternal mental health and welfare.

Methods: Undertaking extensive searches of Scopus, PubMed, PsycINFO, and Google Scholar, we have incorporated studies published from 2013 onwards that examined the occurrence of PTSD following emergency C-sections.
