AI Article Synopsis
- The study examines how childhood trauma interacts with genetic variations in the serotonin (5-HT) and endocannabinoid (eCB) systems to predict burnout in individuals.
- Results show that certain genetic polymorphisms, especially FAAH rs324420, influence the relationship between childhood trauma, job stress, and burnout symptoms like reduced personal accomplishment and emotional exhaustion.
- It concludes that these genetic factors together may impact how childhood experiences affect burnout, highlighting the complexity of these interactions in mental health.
Article Abstract
Background: Interactions between the serotonin (5-HT) and endocannabinoid (eCB) systems have been reported in the psychopathology of stress-related symptoms, while their interplay in regulating the relationship between childhood trauma and burnout remains unclear. In this study, we investigated the interaction of childhood trauma with genetic polymorphisms in these two systems in predicting burnout.
Methods: Burnout, childhood trauma, and job stress were assessed using rating scales in 992 general occupational individuals. Genetic polymorphisms including HTR2A rs6313, 5-HTT rs6354 and FAAH rs324420, were genotyped. Linear hierarchical regression analysis and PROCESS macro in SPSS were used to examine two- and three-way interactions.
Results: There were significant interactions of job stress × HTR2A rs6313 and childhood abuse × FAAH rs324420 on reduced personal accomplishment. Moreover, we found significant three-way interactions of childhood abuse × FAAH rs324420 × HTR2A rs6313 on cynicism and reduced personal accomplishment, childhood abuse × FAAH rs324420 × 5-HTT rs6354 on emotional exhaustion, and childhood neglect × FAAH rs324420 × 5-HTT rs6354 on reduced personal accomplishment. These results suggest that the FAAH rs324420 A allele carriers, when with some specific genetic polymorphisms of 5-HT system, would show more positive associations between childhood trauma and burnout.
Conclusions: Genetic polymorphisms in the 5-HT and eCB systems may jointly moderate the impact of childhood trauma on burnout.

Childhood maltreatment exposure (CME) increases the risk of adverse long-term health consequences for the exposed individual. Animal studies suggest that CME may also influence the health and behaviour in the next generation offspring through CME-driven epigenetic changes in the germ line. Here we investigated the associated between early life stress on the epigenome of sperm in humans with history of CME.

Childhood abuse represents one of the most potent risk factors for the development of psychopathology during childhood, accounting for 30-60% of the risk for onset. While previous studies have separately associated reductions in gray matter volume (GMV) with childhood abuse and internalizing psychopathology (IP), it is unclear whether abuse and IP differ in their structural abnormalities, and which GMV features are related to abuse and IP at the individual level. In a pooled multisite, multi-investigator sample, 246 child and adolescent females between the ages of 8-18 were recruited into studies of interpersonal violence (IPV) and/or IP (i.

Background: The long-term impact of childhood maltreatment (CM) on an individual's physical and mental health is suggested to be mediated by altered neurodevelopment. However, the exact neurobiological consequences of CM remain unclear.
Methods: The present study aimed to investigate the relationship between CM and brain age based on structural magnetic resonance imaging data from a sample of 214 adults.

Background: The present study examines the interplay between epistemic stance, attachment dimensions, and childhood trauma in relation to specific demographic factors and mental health outcomes. This study aims to understand how these factors form distinct profiles among individuals, to identify those at risk of mental health concerns.
Method: Latent Profile Analysis (LPA) was employed on a dataset from the general population (n = 500) to identify subgroups of individuals based on their epistemic stance (mistrust and credulity), attachment dimensions, and childhood trauma.

Background/purpose: Adverse childhood experiences (ACEs) have been linked to various detrimental life outcomes, including an increase in threat sensitivity and depressive symptoms. Studies have also found an association between ACEs and firearm ownership. To date, no study has assessed whether ACEs have direct or indirect effects on defensive gun use (DGU) through these risk factors.
