Stumps A, Bounoua N, Sadeh N. Emotional reactivity linking assaultive trauma and risky behavior: Evidence of differences between cisgender women and men. J Trauma Stress 2024; 37:492-503. [PMID: 38454638 PMCID: PMC11176033 DOI: 10.1002/jts.23028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 01/09/2024] [Accepted: 02/01/2024] [Indexed: 03/09/2024]
Abstract
Accumulating evidence suggests that trauma exposure is positively associated with future engagement in risky behavior, such as substance misuse, aggression, risky sex, and self-harm. However, the psychological factors driving this association and their relevance across gender groups require further clarification. In a community sample of 375 adults with a high rate of trauma exposure (age range: 18-55 years, M = 32.98 years, SD = 10.64; 76.3% assaultive trauma exposure), we examined whether emotional reactivity linked lifetime assaultive trauma exposure with past-month risky behavior. We also explored whether this model differed for cisgender women (n = 178, 47.6%) and men (n = 197, 52.5%). As hypothesized, assaultive trauma was positively related to emotional reactivity, β = .20, SE = 0.03, t(369) = 3.65, p < .001, which, in turn, partially accounted for the association between assaultive trauma and past-month risky behavior, indirect effect: β = .03, SE = 0.01, 95% bootstrapped CI [0.01, 0.06]. Gender moderated this association such that assaultive trauma was indirectly associated with risky behavior via emotional reactivity for women but not for men, index moderation: B = -0.03, SE = 0.02, 95% bootstrapped CI [-0.07, -0.01]. Cross-sectional results suggest that emotional reactivity may be a proximal target for clinical intervention to aid in the reduction of risky behavior among women.

Leech K, Stapleton P, Patching A. A roadmap to understanding interoceptive awareness and post-traumatic stress disorder: a scoping review. Front Psychiatry 2024; 15:1355442.

Abstract
The concept of interoception has existed since the beginning of the 1900s. It is suggested that humans can observe feelings arising from the body that allows them to develop a sense of their emotional status and physical condition. The term interoceptive awareness appears to originate with clinicians working with individuals who had experienced trauma, in particular Post Traumatic Stress Disorder (PTSD). The purpose of this scoping review was to provide an overview of the existing literature surrounding the combination of these two themes: interoceptive awareness and PTSD. A total of 226 articles were initially screened and 52 articles were retained for comprehensive review. Nine articles were excluded, resulting in 43 studies included in the review. The review aimed to answer: (a) how is interoceptive awareness defined? (b) how is interoceptive awareness measured? (c) what is the function of interoceptive awareness? (d) is there/what is the relationship between interoceptive awareness and PTSD? The scoping review identified nine terms that are used synonymously throughout the literature surrounding interoceptive awareness and PTSD, and three primary ways in which interoceptive awareness is measured in relation to PTSD. The primary function documented was the role interoceptive awareness played in an individual's ability to regulate their emotions, and the most common and compelling function emerging was the association with emotion regulation. The evidence supports the utilisation of a definition of interoceptive awareness to include one that includes the quality of cognitive appraisal and focuses on the adaptive mindful approach to internal physical sensations as opposed to the heightened ruminative self-focus. Limitations and future research are suggested.

Exploring the connection between childhood trauma, dissociation, and borderline personality disorder in forensic psychiatry: a comprehensive case study. Front Psychol 2024; 15:1332914. [PMID: 38464619 PMCID: PMC10920285 DOI: 10.3389/fpsyg.2024.1332914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 01/30/2024] [Indexed: 03/12/2024] Open
Abstract
This case study examines the complex relationship between childhood trauma, dissociation, and Borderline Personality Disorder (BPD) within the context of forensic psychiatry. It focuses on a young murder defendant named "Paul," who has experienced various traumatic events, including childhood maltreatment and domestic violence. These experiences have led to dissociative states marked by high emotional intensity, particularly of an aggressive nature, and impaired impulse control, resulting in violent behavior during dissociative episodes. The study employs advanced assessment tools like Raven's Standard Progressive Matrices (SPM), the Millon Clinical Multiaxial Inventory-III (MCMI-III), and the Level of Service/Case Management Inventory (LS/CMI) to gain a comprehensive understanding of Paul's psychopathological condition, risk factors, and rehabilitation needs. The LS/CMI assessment highlights a high risk of recidivism, mainly influenced by family relationships, educational challenges, interpersonal connections, and aggressive tendencies. To address the multifaceted needs of individuals like Paul, the study emphasizes the importance of using transdiagnostic models for trauma and dissociation. This approach informs tailored treatment programs that include processing past traumatic experiences, improving self-identity, nurturing healthy relational patterns, and enhancing emotional regulation. Although this study is based on a single case, it serves as a model for integrating assessment tools and theoretical-clinical models in the field of forensic psychiatry. Understanding the intricate dynamics of childhood trauma, dissociation, and BPD is crucial for making informed decisions, conducting risk assessments, and developing rehabilitation programs within the justice system. Future research should expand the scope of cases and further validate assessment tools to advance our understanding of this complex relationship.

Abstract
Previous studies have primarily focused on the contemporaneous, short-term and medium-term effects of the childhood left-behind experience on subsequent health, but ignored its long-term effects and the mediating mechanisms of health outcomes. Using nationally representative data from the 2018 China Labor-force Dynamic Survey, this study uses self-rated health as a measure of health outcomes to examine the long-term effects of the left-behind experience and elucidate the underlying mechanisms that contribute to health inequality from a life-course perspective. The results show: (1) the childhood left-behind experience exerts a long-term negative impact on self-rated health in adulthood, and this impact persists and does not fade over time after ending the left-behind status; (2) the influence of the childhood left-behind experience on self-rated health demonstrates a cumulative disadvantage effect, with longer duration of being left-behind resulting in greater negative impacts; additionally, there's a critical window effect, with earlier left-behind experience leading to more significant negative outcomes; (3) the experience of being left behind during childhood has a negative impact and threshold effect on social trust in adulthood, meaning that the left-behind experience negatively affects social trust, but the duration of being left behind doesn't exacerbate this reduction; and (4) social trust is a key mediating factor between left-behind experiences and health, explaining 8.70% of this effect, and explaining 12.15% and 7.71% of mediation effects for adults with left-behind experience in middle and primary school stages, respectively.

Abstract
Introduction Internet addiction (IA) is common among adolescents and may have severe consequences. This study aimed to investigate the prevalence and factors associated with IA among middle school students of Hunan Province, China. Relevance between IA and childhood trauma was also explored. Methods One thousand six hundred ten students were enrolled in this cross-sectional study. Data collected included demographics; internet addiction (revised-Chen internet addiction scale); childhood trauma (CTQ-SF); depression, anxiety, and stress symptoms (DASS-21); suicidal behaviors, as well as non-suicidal self-injury (NSSI). Cramer's V analysis, univariable logistic regression and multivariable logistic regression were used for associations and identifying independent relevance of IA, respectively. Results The prevalence of IA was 12.8%. Cramer's V analysis showed that IA was associated with emotional abuse, emotional and physical neglect, NSSI, suicidal behaviors, stress, anxiety and depressive symptoms, physical disorder history. Regression analysis showed that IA was independently associated with emotional neglect (OR = 3.062, 95% CI: 2.083, 4.501, p < 0.001); physical neglect (OR = 2.328; 95% CI: 1.590, 3.409, p < 0.001); depressive symptoms (OR = 2.218, 95% CI: 1.467, 3.353, p < 0.001) nationality (OR = 1.888, 95% CI: 1.034, 3.447, p = 0.006) and age (OR = 1.253, 95% CI: 1.066, 1.471, p = 0.006). Discussion IA is common among middle school students. Attention should be paid to students with childhood trauma since they have a higher risk for IA, which may increase the risk for suicidal behaviors.

Abstract
Fear extinction is the basis of exposure therapies for posttraumatic stress disorder (PTSD), but half of patients do not improve. Predicting fear extinction in individuals with PTSD may inform personalized exposure therapy development. The participants were 125 trauma-exposed adults (96 female) with a range of PTSD symptoms. Electromyography, electrocardiogram, and skin conductance were recorded at baseline, during dark-enhanced startle, and during fear conditioning and extinction. Using a cross-validated, hold-out sample prediction approach, three penalized regressions and conventional ordinary least squares were trained to predict fear-potentiated startle during extinction using 50 predictor variables (5 clinical, 24 self-reported, and 21 physiological). The predictors, selected by penalized regression algorithms, were included in multivariable regression analyses, while univariate regressions assessed individual predictors. All the penalized regressions outperformed OLS in prediction accuracy and generalizability, as indexed by the lower mean squared error in the training and holdout subsamples. During early extinction, the consistent predictors across all the modeling approaches included dark-enhanced startle, the depersonalization and derealization subscale of the dissociative experiences scale, and the PTSD hyperarousal symptom score. These findings offer novel insights into the modeling approaches and patient characteristics that may reliably predict fear extinction in PTSD. Penalized regression shows promise for identifying symptom-related variables to enhance the predictive modeling accuracy in clinical research.

Abstract
Although the association between cognitive performances and the onset of psychiatric disorders has been widely investigated, limited research on the role of childhood trauma or early life stress (CT/ELS), and whether this role differs between clinical and non-clinical cohorts is available. This systematic review aims at filling this gap, testing whether the occurrence of CT/ELS and its subtypes are associated with cognitive domains (general cognitive ability, executive functions, working memory, attention, processing speed, verbal/visual memory) in patients with psychiatric disorders and in non-clinical populations. This study followed the PRISMA 2020 guidelines and the Newcastle-Ottawa scale for quality assessment. The search was performed until May 2022. Seventy-four studies were classified as eligible. The graphical representations of the results reported an association between exposure to CT/ELS and worse general cognitive ability, verbal/visual memory, processing speed and attention in patients affected by anxiety, mood and psychotic disorders, and that specific CT/ELS subtypes (physical neglect, physical/sexual abuse) can differentially influence specific cognitive abilities (executive functions, attention, working memory, verbal/visual memory). In non-clinical cohorts we found associations between CT/ELS exposure and impairments in executive functions, processing speed and working memory, while physical neglect was related to general cognitive ability and working memory. Concerning the emotional abuse/neglect subtypes in both populations, the results indicated their involvement in cognitive functioning; however, the few studies conducted are not enough to reach definitive conclusions. These findings suggest an association of CT/ELS with specific cognitive deficits and psychopathology.

Abstract
Evidence suggests that child maltreatment is a risk factor for adolescent suicidal behavior. However, the differential influence of distinct forms of child maltreatment on adolescent suicide attempts is understudied and the factors that might exacerbate or ameliorate these associations warrant attention. We examined the associations between two distinct forms of child maltreatment (threat and deprivation) and suicide attempt history, and investigated whether executive function domains moderated these associations. Participants were 119 adolescents (M = 15.24, SD = 1.46, 72.3% female) recruited from an inpatient psychiatric hospital during hospitalization for suicidal thoughts and behaviors. Results indicated that the executive function domains of initiation, shifting, and planning/organization moderated the associations between threat and suicide attempt history. Associations between threat and suicide attempt history were significant only when initiation and shifting T-scores were lower (OR = 1.22, p = .03 and OR = 1.32, p = .01, respectively). The association between threat and suicide attempt history trended toward significance when planning/organization T-scores were lower (OR = 1.15, p = .10). None of the executive function domains moderated the link between deprivation and suicide attempt history. Findings highlight the need for research investigating whether initiation, shifting, and planning/organization might be amendable to intervention in the context of threat-related child maltreatment.

Abstract
BACKGROUND Cognitive impairment is a core feature of mood disorders and has been identified as an important treatment target. A better understanding of the factors contributing to cognitive impairment in mood disorders would be beneficial in developing interventions to address cognitive impairment. One key factor is childhood trauma. The aim of this review was to systematically synthesise and review research examining associations between reported childhood trauma and cognitive functioning in mood disorders. METHODS Studies in adult samples examining the relationship between objective cognitive function and reported childhood trauma in major depressive disorder and/or bipolar disorder (in-episode or euthymia) were identified. Searches were conducted on PubMed, Embase and PsycINFO until January 2022. A narrative review technique was used due to the heterogeneity of group comparisons, cognitive tests and data analysis across studies. RESULTS Seventeen studies met the criteria for inclusion (mood disorders N = 1723, healthy controls N = 797). Evidence for childhood trauma being related to poorer cognitive functioning was consistent across global cognitive functioning and executive function domains for euthymic patients and psychomotor speed for in-episode patients. There was mixed evidence for verbal learning and memory and executive function for in-episode patients. Identification of patterns within other domains was difficult due to limited number of studies. CONCLUSION Findings from this review suggest childhood trauma is associated with poorer cognitive functioning in people with mood disorders. Targeted interventions to improve cognition may be warranted for this group.

Abstract
BACKGROUND Childhood trauma is commonly experienced by individuals diagnosed with bipolar disorder (BP). In BP, childhood trauma is related to a more severe clinical course, but its association with cognition remains unclear. METHODS This study evaluated 405 adult participants diagnosed with BP and 136 controls. Participants completed the Childhood Trauma Questionnaire and a comprehensive neuropsychological battery. High versus low childhood trauma was defined with one standard deviation above the control participant's mean Childhood Trauma Questionnaire score. Neuropsychological data was transformed into eight cognitive factors, including four executive functioning, auditory and visual memory, fine motor, and emotion processing. Multivariate analysis of covariance evaluated group differences in cognition, while adjusting for covariates. RESULTS There were significant differences among the three groups, F(16, 968) = 4.05, p < .001, Wilks' Λ = 0.88, partial η2 = 0.06. Comparing the high and low trauma BP groups, high trauma was related to lower auditory and visual memory factor scores (p < .05). As compared to controls, the BP high trauma group had lower scores on six of eight factors (all p < .01), while the BP low trauma group had lower scores on four of eight factors (all p < .01). LIMITATIONS Analyses of factor score do not address which aspect of the memory process is affected and biomarkers may help guide interventions addressing underlying biological process. CONCLUSIONS Adults diagnosed with BP with higher childhood trauma have worse memory functioning, beyond the lower childhood trauma BP group, highlighting the importance of understanding the long-term cognitive outcomes of childhood trauma.

Abstract
OBJECTIVE We investigated whether childhood social isolation was associated with retinal neural layer changes in adulthood, and whether this association was independent of other childhood or adulthood risk factors, including adult social isolation. METHODS Participants were members of the Dunedin Multidisciplinary Health and Development Study, a longitudinal population-based birth cohort from Aotearoa New Zealand ( n = 1037), born 1972 to 1973 and followed until age 45 years, with 94% of the living cohort still participating. Social isolation was recorded prospectively at ages 5, 7, 9, and 11 years, from teacher and parent report. Retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer thicknesses were measured via optical coherence tomography at age 45 years. RESULTS Childhood social isolation was associated with thinner average RNFL ( B = -0.739, p = .02), nasal RNFL ( B = -1.118, p = .005), and inferior RNFL ( B = -1.524, p = .007), although only nasal RNFL remained significant after adjustment. These associations were not fully explained by other psychosocial or physical health risk factors in childhood or adulthood, nor were they mediated by adult loneliness or social support. CONCLUSIONS Childhood social isolation was an independent predictor of RNFL thickness in middle age. Highlighting prospective links between childhood psychosocial adversity and retinal neuronal measures will help to inform future research into the utility of retinal neuronal thickness as a biomarker for neurodegeneration.

The influence of childhood maltreatment on trait depression in patients with major depressive disorder: A moderated mediation model of rumination and mindful attention awareness. J Affect Disord 2023; 331:130-138. [PMID: 36963511 DOI: 10.1016/j.jad.2023.03.052] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 03/06/2023] [Accepted: 03/18/2023] [Indexed: 03/26/2023]
Abstract
Major depressive disorder (MDD) is one of the most prevalent psychiatric disorders. Individuals who were exposed to childhood maltreatment might be an especially vulnerable group and were more likely to meet the diagnostic criteria for depression than those who were not. Trait depression refers to a personality trait predisposition to depression, expressed as the frequency of symptoms rather than a transient depressive mood state. Clarifying the relationship between childhood maltreatment and trait depression in patients with MDD has therefore become an important field of research. Childhood Trauma Questionnaire-Short Form (CTQ-SF), Ruminative Responses Scale (RRS), State-Trait Depression Scale (ST-DEP), and Mindful Attention Awareness Scale (MAAS) were used as research instruments. SPSS 23.0 statistical software was used for statistical analysis and examined the moderated mediation models. A total of 288 patients with MDD were included in this study. After standardization of the variables, the model revealed childhood maltreatment was positively associated with trait depression (β = 0.215, p < 0.001) and that rumination partially mediated the effect between childhood trauma and trait depression. Mindfulness moderated the association between rumination and trait depression in depressed patients (β = 0.171, p < 0.001). Simple slope tests showed that rumination significantly predicted trait depression in patients with high levels of mindfulness (bsimple = 0.460, p < 0.001, 95%CI = [0.339, 0.581]), while this predictive effect was not significant in patients with low levels (bsimple = 0.119, p = 0.097, 95%CI = [-0.022, 0.261]). After adding mediating variables, we found that the negative impact of childhood maltreatment on trait depression was both directly and indirectly through the patients' own ruminative levels. However, mindfulness performed a critical moderating role in the overall mediating model, aggravating the negative impact of childhood maltreatment on trait depression. There are several limitations in this study: the history of childhood maltreatment was reviewed and reported; the MAAS was a single-dimensional questionnaire that fails to measure the content of other mindfulness factors; cross-sectional data could not be used to infer the causal relationship between variables.

Abstract
OBJECTIVE A growing body of evidence reports on the effect of different types of childhood abuse on the structural and functional architecture of the brain. In the present study, we aimed to investigate the differences in cortical thickness according to specific types of childhood abuse between patients with major depressive disorder (MDD) and healthy controls (HCs). METHODS A total of 61 patients with MDD and 98 HCs were included in this study. All participants underwent T1-weighted magnetic resonance imaging, and the occurrence of childhood abuse was assessed using the Childhood Trauma Questionnaire. We investigated the association between whole-brain cortical thickness and exposure to any type of childhood abuse and specific type of childhood abuse in the total sample using the FreeSurfer software. RESULTS No significant difference was reported in the cortical thickness between the MDD and HC groups nor between the "any abuse" and "no abuse" groups. Compared to no exposure to childhood sexual abuse (CSA), exposure to CSA was significantly associated with cortical thinning in the left rostral middle frontal gyrus (p=0.00020), left (p=0.00240), right fusiform gyri (p=0.00599), and right supramarginal gyrus (p=0.00679). CONCLUSION Exposure to CSA may lead to cortical thinning of the dorsolateral prefrontal cortex, which is deeply involved in emotion regulation, to a greater extent than other types of childhood abuse.

An investigation of the utility of the Australian Guide to the diagnosis of fetal alcohol spectrum disorder in young children. Alcohol Clin Exp Res 2023; 47:486-500. [PMID: 36810987 DOI: 10.1111/acer.15012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 12/19/2022] [Accepted: 01/04/2023] [Indexed: 02/23/2023]
Abstract
BACKGROUND Early diagnosis of children with fetal alcohol spectrum disorder (FASD) assists in implementing critical early support. The challenge lies in having a diagnostic process that enables valid and reliable assessment of domains of functioning in young children, with the added complexity that many children will also have co-occurring exposure to childhood adversity that is likely to impact these domains. METHODS The aim of this study was to test a diagnostic assessment of FASD in young children using the Australian Guide to the Diagnosis of FASD. Ninety-four children (aged 3 to 7 years) with confirmed or suspected prenatal alcohol exposure were referred to two specialist FASD clinics for assessment in Queensland, Australia. RESULTS There was a significant risk profile with 68.1% (n = 64) children having had contact with child protection services, and most children living in kinship (n = 22, 27.7%) or foster (n = 36, 40.4%) care. Forty-one percent of the children were Indigenous Australians. The majority (64.9%, n = 61) of children met criteria for FASD, 30.9% were classified as "At Risk" for FASD (n = 29), and 4.3% received no FASD diagnosis (n = 4). Only 4 (4%) children were rated as severe for the brain domain. Over 60% of children (n = 58) had two or more comorbid diagnoses. Sensitivity analyses indicated that the removal of comorbid diagnoses in the Attention, Affect Regulation, or Adaptive Functioning domains resulted in a change in 7 of 47 cases (15%) to an "At Risk" designation. CONCLUSIONS These results highlight the complexity of presentation and the extent of impairment in the sample. The use of comorbid diagnoses to substantiate a "severe" designation in specific neurodevelopmental domains raises the question of whether there were false-positive diagnoses. The complexity of determining causal relationships between exposure to PAE and early life adversity on developmental outcomes continues to be a challenge in this young population.

Abstract
Background: Early trauma predicts poor psychological and physical health. Glutamatergic synaptic processes offer one avenue for understanding this relationship, given glutamate's abundance and involvement in reward and stress sensitivity, emotion, and learning. Trauma-induced glutamatergic excitotoxicity may alter neuroplasticity and approach/avoidance tendencies, increasing risk for psychiatric disorders. Studies examine upstream or downstream effects instead of glutamatergic synaptic processes in vivo, limiting understanding of how trauma affects the brain.Objective: In a pilot study using a previously published data set, we examine associations between early trauma and a proposed measure of synaptic strength in vivo in one of the largest human samples to undergo Carbon-13 (13C MRS) magnetic resonance spectroscopy. Participants were 18 healthy controls and 16 patients with PTSD (male and female).Method: Energy per cycle (EPC), which represents the ratio of neuronal oxidative energy production to glutamate neurotransmitter cycling, was generated as a putative measure of glutamatergic synaptic strength.Results: Results revealed that early trauma was positively correlated with EPC in individuals with PTSD, but not in healthy controls. Increased synaptic strength was associated with reduced behavioural inhibition, and EPC showed stronger associations between reward responsivity and early trauma for those with higher EPC.Conclusion: In the largest known human sample to undergo 13C MRS, we show that early trauma is positively correlated with EPC, a direct measure of synaptic strength. Our study findings have implications for pharmacological treatments thought to impact synaptic plasticity, such as ketamine and psilocybin.

Abstract
Purpose There is a lack of research on childhood sexual abuse (CSA) experienced by men, with even less research examining long term neurophysiological repercussions. This study explored the neurophysiology of the brain at rest to examine the influence of CSA on resting state functional connectivity (RSFC) into adulthood. Methods RSFC was examined with functional magnetic resonance imaging (fMRI) within the default mode, salience and limbic networks in men with CSA histories, with and without post-traumatic stress disorder (PTSD; CSA + PTSD n = 7, CSA-PTSD n = 9), and men without a CSA history nor PTSD (n = 13). Results CSA + PTSD participants had increased functional connectivity (FC) in the medial prefrontal cortex (mPFC) from the default mode network seed compared to participants with CSA-PTSD. Both CSA groups showed significantly less FC in the striatal-thalamic circuits of the salience network than the control group. Similarly, the robust FC between the bilateral amygdalae and the mPFC that was notable in control participants, was not exhibited in participants who experienced CSA with or without PTSD histories. Conclusions These findings demonstrate that intrinsic neurophysiological differences in limbic, salience and default mode network connectivity are apparent even during a resting state between the groups of participants. This is preliminary evidence of long-term neurophysiological effects of CSA in men with PTSD, and even in those without. Importantly, these findings can validate the lived experiences of males with CSA histories and guide researchers and clinicians to potential avenues to support their well-being.

Abstract
BACKGROUND Research has demonstrated that chronic stress exposure early in development can lead to detrimental alterations in the orbitofrontal cortex (OFC)-amygdala circuit. However, the majority of this research uses functional neuroimaging methods, and thus the extent to which childhood trauma corresponds to morphometric alterations in this limbic-cortical network has not yet been investigated. This study had two primary objectives: (i) to test whether anatomical associations between OFC-amygdala differed between adults as a function of exposure to chronic childhood assaultive trauma and (ii) to test how these environment-by-neurobiological effects relate to pathological personality traits. METHODS Participants were 137 ethnically diverse adults (48.1% female) recruited from the community who completed a clinical diagnostic interview, a self-report measure of pathological personality traits, and anatomical MRI scans. RESULTS Findings revealed that childhood trauma moderated bilateral OFC-amygdala volumetric associations. Specifically, adults with childhood trauma exposure showed a positive association between medial OFC volume and amygdalar volume, whereas adults with no childhood exposure showed the negative OFC-amygdala structural association observed in prior research with healthy samples. Examination of the translational relevance of trauma-related alterations in OFC-amygdala volumetric associations for disordered personality traits revealed that trauma exposure moderated the association of OFC volume with antagonistic and disinhibited phenotypes, traits characteristic of Cluster B personality disorders. CONCLUSIONS The OFC-amygdala circuit is a potential anatomical pathway through which early traumatic experiences perpetuate emotional dysregulation into adulthood and confer risk for personality pathology. Results provide novel evidence of divergent neuroanatomical pathways to similar personality phenotypes depending on early trauma exposure.

Age-related no-go P300 amplitudes are moderated by exposure to early-life stress. Int J Psychophysiol 2022; 180:1-9.

Abstract
Deficits in inhibitory control are common with advancing age and may underlie declines in other complex cognitive functions. The inhibitory P300 event-related potential (ERP) generally decreases in amplitude with age, reflecting deficits in inhibitory performance evaluation and adaptation, with possible generators including precentral and inferior frontal gyri and midcingulate and parietal cortex. Exposure to early-life stress (ELS) is also associated with deficits in inhibitory control, smaller P300 amplitudes, and dysfunction in regions associated with P300 generation. Although biopsychosocial effects of ELS are evident in older adulthood, the influence of ELS on neural processes in later life is unknown. In the current study, 13 young adults and 21 healthy older adults completed a high-accuracy go/no-go task and the Juvenile Victimization Questionnaire (JVQ), an indicator of ELS. Regression analyses revealed significant central-parietal models, with smaller P300 amplitudes predicted by both older age and greater exposure to ELS. Age group*ELS interactions moderated P300 prediction at central and centro-parietal electrodes, such that older age predicted smaller P300 amplitudes only in those with lower to moderate ELS. Amplitudes did not significantly differ by age in those with higher ELS. Post-hoc within-age group correlations showed that greater ELS was associated with smaller P300 amplitudes in young adults. However, greater ELS was modestly associated with larger central amplitudes in older adults, potentially suggestive of anterior age-related compensatory recruitment to maintain high task performance. These findings suggest long-lasting neural implications of ELS that interact with normative neuro-cognitive aging processes, such that ELS may be an important risk factor for age-related cognitive decline.

Abstract
Executive functioning (EF), or a set of related cognitive skills that facilitate goal-oriented behavior, is a critical aspect of adaptive development. Mounting research indicates that exposure to environmental threats during the preschool years jeopardizes EF; however, the extent and mechanisms through which early exposure to intimate partner violence (IPV) influences children's EF are unknown. Using data from an eight-year longitudinal investigation of mothers who had experienced IPV and their preschool-aged children (N = 120), this study examined the relative influence of recent and remote IPV exposure on speeded control-a component of EF influenced by processing speed-in late childhood. Results indicated that preschoolers' IPV exposure had a significant negative impact on their speeded control eight years later, and this relation was mediated by the remote effects of IPV on their mothers. Specifically, IPV was positively associated with maternal depression, which in turn contributed to greater use of negative parenting strategies when children were of preschool age. Children's IPV exposure during late childhood was not predictive of their concurrent speeded control. These findings lend further evidence to the notion that the preschool years are a sensitive period for the mastery of EF skills and that IPV exposure is a distinct risk factor that can have protracted effects on children's cognitive development. Further, this study points to modifiable environmental risk factors, which, through targeted prevention and intervention efforts, could promote EF across the lifespan.

Abstract
Children exposed to adverse childhood experiences (ACEs) and pervasive interpersonal traumas may go on to develop PTSD and, in most cases, will further undergo a significant shift in their developmental trajectory. This paper examines contemporary research on Developmental Trauma (DT), which is inextricably linked to disruptions in social cognition, physiological and behavioral regulation, and parent-child attachments. Developmental trauma associated with early experiences of abuse or neglect leads to multi-faceted and longstanding consequences and underscores critical periods of development, complex stress-mediated adaptations, and multilevel, trans-theoretical influences in the diagnostic formulation and treatment of traumatized children, adolescents, and adults. Psychological and medical correlates of Developmental Trauma Disorder are considered, and directions for future research are discussed.

Abstract
Sexual offending is a global problem but is particularly prevalent on the African continent and in South Africa. Childhood experiences related to abuse, alcohol use, and criminal activities in the household and community has been associated with an increased risk for violence perpetration in adulthood. Less is known about sexual violence perpetration, especially in the South African context. In this study, the experiences of incarcerated male perpetrators of rape in South Africa are investigated along with the collective social context and individual childhood experiences that potentially contribute to rape perpetration. Eighteen male perpetrators of rape who were inmates at Westville Correctional Services in KwaZulu Natal, South Africa, were interviewed. The semi-structured in-depth qualitative interviews were transcribed, coded and annotated using an interpretive paradigm and thematic analysis approach. Five main themes emerged from the research and included (1) childhood trauma and adverse events, e.g., an absent father, being raised without parents, exposure to criminal or violent behavior, physical abuse, sexual abuse and poverty, (2) understanding rape, e.g., rape as sex by force and without consent, rape as a violent act, rape as sex with a minor, myths about rape (3) substance abuse, e.g., history of alcohol and drug use, and intoxication during rape perpetration, (4) gender roles and avoiding responsibility, e.g., victim blaming, rape as male prerogative, transactional sex, being framed or set-up, ignoring an ancestral call and (5) recidivism. The findings revealed that all rape perpetrators were exposed to at least one childhood trauma type. Family and community violence and criminality was common. Most participants avoided taking responsibility for their actions and blamed the victim and recidivism/prior convictions were often reported. The findings demonstrate the complex personality dynamic involved in the cycle of abuse and the evolution of criminal behavior, starting as a victim and ending as a perpetrator. The findings also highlight the need for interventions aimed at reducing childhood trauma exposure and improving the social and relational context of those at risk for childhood neglect and abuse.

Abstract
Social communication forms the foundation of human relationships. Social communication, i.e., the appropriate understanding and use of verbal and non-verbal communication within a social context, profoundly impacts mental health across the lifespan and is also highly vulnerable to neurodevelopmental threats and social adversities. There exists a strong interconnection between the development of language and other higher cognitive skills, mediated, in part, through the early attachment relationship. Consideration of how attachment links to brain development can help us understand individuals with social communication difficulties across the lifespan. The early attachment relationship supports the development of the foundational constructs of social communication. In this paper, a neuropsychological perspective was applied to social communication, which integrated evidence from early attachment theory, examining the underpinnings of social communication components identified by the SoCom model, namely socio-cognitive, socio-emotional, and socio-linguistic constructs. A neuropsychological perspective underscores the importance of interdisciplinary collaboration. This should also inform approaches to prevention, policy, intervention, and advocacy for individuals with or at risk for social communication impairments, as well as their families.

Abstract
BACKGROUND Research has shown a strong relationship between psychosis and sexual assault. Theories on developmental trauma as a causal factor for psychosis suggest that exposure to sexual trauma in childhood would have a stronger association with psychosis than sexual trauma in adulthood. We hypothesized that exposure to sexual trauma earlier in childhood and adolescence would be more strongly associated with hallucinations, delusional beliefs and psychotic disorder than sexual trauma that occurred later in life. METHODS Using the 2007 and 2014 Adult Psychiatric Morbidity Surveys (N = 14,949) we calculated the prevalence of sexual assault, hallucinations, delusional beliefs, and psychotic disorder. We used logistic regression to examine the relationship between age of exposure to sexual assault (first exposure <16 vs first exposure ≥16) and odds of hallucinations, delusions, and psychotic disorder. RESULTS Sexual assault at any age was associated with an increased odds of hallucinations (aOR = 2.00, 95%CI = 1.63-2.46), delusional beliefs (aOR = 2.55, 95%CI = 2.24-2.89) and psychotic disorder (aOR = 5.28, 95%CI = 3.59-7.76). There was no significant difference, however, in the prevalence of hallucinations, delusional beliefs or psychotic disorders in individuals first exposed to sexual assault <16 and individuals first exposed ≥16. CONCLUSIONS Contrary to our hypothesis, we did not find evidence that exposure to sexual assault in childhood and adolescence was more strongly associated with hallucinations, delusional beliefs or psychotic disorder than exposure to sexual assault age >16. Our findings do not support the idea that childhood and adolescence are uniquely sensitive periods for the emergence of psychotic experiences or psychotic disorder in relation to sexual trauma.

Abstract
After reaching the age of criminal responsibility, children are deemed capable of having committed criminal offenses. In this regard, the level of criminal responsibility depends on cognitive development and the type of offense committed. Cognitive development is a process of the growth of perception, thinking and reasoning in children. This concept is frequently referred to in cognitive neuroscience literature. Recently, the U.S. Supreme Court's decision in Roper v Simmons has substantially changed attitudes toward juvenile delinquency, considering the fact that cognitive development continues until early adulthood. The present study attempts to scrutinize this case and explain cognitive development by its factors from an interdisciplinary perspective, combining methods and theories from neuroscience and criminal law.

Towards a new understanding of pregnancy denial: the misunderstood dissociative disorder. Arch Womens Ment Health 2022; 25:51-59.

Abstract
Pervasive pregnancy denial is a misunderstood reproductive anomaly which compromises the health of both mother and the developing fetus. Because in extreme cases, the death of the neonate at the hands of his/her mother has criminal repercussions, research has attempted to explain the origins of this clinical phenomenon. The purpose of this review is to analyze the evolution of understanding the association between pregnancy denial and neonaticide. This paper identifies the consistent similarities in symptom presentation, particularly dissociation, when a denied pregnancy ends with the death of the newborn. The common thread across the progression of the literature over time serves as a foundation for considering the development of diagnostic criteria for future inclusion in the Diagnostic and Statistical Manual of Mental Disorders. This paper reviews the seminal research from 1969 to current research up to 2020 addressing pregnancy denial and its connection to neonaticide. Peer reviewed and published articles related to key terms around "pregnancy denial," "pregnancy concealment," "neonaticide," and "dissociation" were retrieved from major databases such as PubMed, PsychINFO, JSTOR, ProQEST, ScienceDirect, and Google Scholar. Reference lists of relevant articles were also scanned to search for further papers pertaining to similarities in symptom presentation across demographic profiles. Papers were excluded if they were not available in English, or if they did not contribute to identifying consistencies in clinical presentation when a pregnancy is denied. There are clear repetitive markers that occur across studies which pertain not only to the frequent absence of certain expected indicators of pregnancy, (i.e. no morning sickness, weight gain, or sensations of fetal movement), but also the misattribution of pregnancy-related symptoms, and the consistent experience of a dissociative episode while giving birth that can unintentionally result in neonaticide. This paper concludes that dissociation is a consistently seen symptom in pervasive pregnancy denial. Dissociation, in addition to other commonly seen symptoms across cases, suggests specific diagnostic criteria that lend themselves to inclusion in the Diagnostic and Statistical Manual of Mental Disorders.

Abstract
Reduced volumes in brain regions of interest (ROIs), primarily from adult samples, are associated with posttraumatic stress disorder (PTSD). We extended this work to children using data from the Adolescent Brain Cognitive Development (ABCD) Study® (N = 11,848; Mage = 9.92). Structural equation modeling and an elastic-net (EN) machine-learning approach were used to identify potential effects of traumatic events (TEs) on PTSD symptoms (PTSDsx) directly, and indirectly via the volumes 300 subcortical and cortical ROIs. We then estimated the genetic and environmental variation in the phenotypes. TEs were directly associated with PTSDsx (r = 0.92) in children, but their indirect effects (r < 0.0004)-via the volumes of EN-identified subcortical and cortical ROIs-were negligible at this age. Additive genetic factors explained a modest proportion of the variance in TEs (23.4%) and PTSDsx (21.3%), and accounted for most of the variance of EN-identified volumes of four of the five subcortical (52.4-61.8%) three of the nine cortical ROIs (46.4-53.3%) and cerebral white matter in the left hemisphere (57.4%). Environmental factors explained most of the variance in TEs (C = 61.6%, E = 15.1%), PTSDsx (residual-C = 18.4%, residual-E = 21.8%), right lateral ventricle (C = 15.2%, E = 43.1%) and six of the nine EN-identified cortical ROIs (C = 4.0-13.6%, E = 56.7-74.8%). There is negligible evidence that the volumes of brain ROIs are associated with the indirect effects of TEs on PTSDsx at this age. Overall, environmental factors accounted for more of the variation in TEs and PTSDsx. Whereas additive genetic factors accounted for most of the variability in the volumes of a minority of cortical and in most of subcortical ROIs.

Abstract
Childhood sexual abuse (CSA) is a common form of childhood maltreatment. Several studies have shown that CSA adversely affects the physical and mental health. Numerous studies have evaluated the prevalence of CSA among females using various instruments. In this meta-analysis, we estimated the rate of CSA among women using the short form of the Childhood Trauma Questionnaire for the first time. Four databases (PsycINFO, PubMed, Cochrane Library, and Embase) were systematically searched for studies published as of April 2, 2018. Forty-eight articles (53 groups of samples) covering 22,224 individuals, including women, from 16 countries were selected. Using the random-effects model, the pooled overall rate of CSA was 24% (95% confidence interval [21%, 27%]). On subgroup analyses, the rate of female CSA in people with mental illness was higher than that in the general group; this result showed variability among different geographical regions.

Abstract
Childhood trauma is strongly associated with poor health outcomes. Although many studies have found associations between adverse childhood experiences (ACEs), a well-established indicator of childhood trauma and diet-related health outcomes, few have explored the relationship between ACEs and diet quality, despite growing literature in epidemiology and neurobiology suggesting that childhood trauma has an important but poorly understood relationship with diet. Thus, we performed a cross-sectional study of the association of ACEs and adult diet quality in the Southern Community Cohort Study, a largely low-income and racially diverse population in the southeastern United States. We used ordinal logistic regression to estimate the association of ACEs with the Healthy Eating Index-2010 (HEI-10) score among 30 854 adults aged 40-79 enrolled from 2002 to 2009. Having experienced any ACE was associated with higher odds of worse HEI-10 among all (odds ratio (OR) 1⋅22; 95 % confidence interval (CI) 1⋅17, 1⋅27), and for all race-sex groups, and remained significant after adjustment for adult income. The increasing number of ACEs was also associated with increasing odds of a worse HEI-10 (OR for 4+ ACEs: 1⋅34; 95 % CI 1⋅27, 1⋅42). The association with worse HEI-10 score was especially strong for ACEs in the household dysfunction category, including having a family member in prison (OR 1⋅34; 95 % CI 1⋅25, 1⋅42) and parents divorced (OR 1⋅25; 95 % CI 1⋅20, 1⋅31). In summary, ACEs are associated with poor adult diet quality, independent of race, sex and adult income. Research is needed to explore whether trauma intervention strategies can impact adult diet quality.

Abstract
Research attempting to identify pathways from childhood maltreatment to adulthood posttraumatic stress symptoms (PTSS) implicates cognitive vulnerabilities that may increase risk for mental health concerns. The present study examined two cognitive vulnerabilities and their relation to PTSS amongst individuals with and without childhood maltreatment histories: attentional control and repetitive negative thinking (RNT). This research surveyed college students (N = 376) on constructs of interest. Results revealed that attentional control and RNT demonstrated significant indirect effects on PTSS (95% CI =.0003, .0336 and 95% CI =.0643, .1857, respectively). Findings suggest that childhood maltreatment severity was related to decreased attentional control and increased RNT, which were then both related to increased PTSS. Interventions for increasing attentional control and decreasing RNT should be implemented and evaluated for young adults with early adversity currently experiencing PTSS.

Abstract
The current study (a) ascertained whether there is a relationship between sexual victimization (SV) and disordered eating (DE) among bisexual women, (b) assessed whether objectification theory explains the relationship, and (c) tested for group differences between bisexual and heterosexual women on SV, DE, and other objectification theory variables. Utilizing a sample of 164 undergraduate bisexual women, there was a significant positive relationship between SV and DE that was serially mediated by self-surveillance and body shame. In addition, bisexual participants endorsed more SV, DE, body shame, and interoceptive deficits than a comparison sample of 335 undergraduate heterosexual women. Implications are discussed.

Abstract
BACKGROUND Childhood trauma and adversity have been linked to chronic pain and pain sensitivity, particularly centralized pain. Yet, there remain numerous gaps in our understanding of this link. PURPOSE We explored the association between nonviolent and violent childhood trauma and a component of centralized pain (i.e., generalized sensory sensitivity) and pain sensitivity using self-report measures of centralized pain and quantitative sensory testing (QST). METHODS Patients scheduled for a total knee arthroplasty (n = 129) completed questionnaires and QST prior to surgery. RESULTS We found that self-report measures of centralized pain (i.e., widespread pain, somatic awareness, and sensory sensitivity) displayed a graded relationship across trauma groups, with patients with a history of violent trauma reporting the highest scores. Univariable multinomial logistic regression analyses showed that higher sensory sensitivity was associated with increased risk of being in the nonviolent trauma group compared to the no trauma group. Furthermore, higher widespread pain, higher somatic awareness, and higher sensory sensitivity distinguished the violent trauma group from the no trauma group. In multivariable analyses, sensory sensitivity is uniquely distinguished between the violent trauma group and the no trauma group. QST did not distinguish between groups. CONCLUSIONS The findings highlight the need for future research and interventions that reduce sensory sensitivity for chronic pain patients with a history of violent childhood trauma.

Abstract
Emerging research has demonstrated that psychosocial trauma exposure may elicit epigenetic changes, with downstream effects on the transcriptional regulation of genes. Epigenome-wide association studies (EWAS) offer an agnostic approach to examine DNA methylation (DNAm) associations and are a valuable tool to aid in the identification of biological pathways involved in posttraumatic stress disorder (PTSD). This study represents the first EWAS of PTSD in an adolescent sample, an important group given the significance of this developmental period regarding both DNAm changes and PTSD risk. The sample (n = 39, M age = 15.41 years, SD = 1.27, 84.6% female) comprised adolescents who experienced interpersonal trauma and were enrolled in a treatment study. Participants were assessed using the UCLA PTSD Reaction Index for DSM-IV-Adolescent Version and provided a blood sample at baseline. Genomic DNA was isolated from whole blood and assayed using the Illumina Infinium MethylationEPIC BeadChip. The primary analysis estimated the associations among individual CpG sites and PTSD symptom scores. Of the 793,575 screened probes tested, two were significant at a false discovery rate (FDR) < 10%. Hypomethylation of both sites was associated with increased PTSD symptom scores. Analysis of differentially methylated regions (DMR) identified a DMR associated with PTSD symptom scores at an FDR < 10%. Results from follow-up models are also discussed. Findings from this preliminary investigation suggest the importance of further research conducted in adolescent samples. The analytic pipeline and results are documented for use in future meta-analytic work as more such samples become available.

Abstract
There is limited understanding of factors across the lifespan that influence pregnant women's respiratory sinus arrhythmia (RSA), which could have implications for their health and offspring development. We examined associations among 162 English- and Spanish-speaking pregnant women's childhood maltreatment history, emotion dysregulation, recent life stress, and resting RSA during the third trimester. Moderated mediation analyses indicated that more severe childhood maltreatment history (95% confidence interval (CI) [0.26, 0.63]) and higher emotion dysregulation (95% CI [0.001, 0.006]) predicted more stress during pregnancy, and childhood maltreatment history interacted with emotion dysregulation to predict resting RSA (95% CI [-0.04, -0.0003]). Exploratory analyses revealed that women's health-related stress during pregnancy mediated the relation between emotion dysregulation and RSA regardless of childhood maltreatment severity (95% CI [-0.007, -0.002]). These findings suggest that women's resting RSA during pregnancy may reflect physical and emotional stress accumulation across the lifespan and that relations between early life adversity and prenatal psychophysiology may be buffered by protective factors, such as emotion regulation. In addition, these findings underscore the importance of distinguishing between types of prenatal stress. Given the implications for women's health and offspring development, we urge researchers to continue exploring factors associated with pregnant women's psychophysiology.

Abstract
Childhood trauma is associated with poor health outcomes in adulthood. Mechanisms for these associations are not well understood because past studies have focused predominantly on populations that have already developed physical and mental health problems. The present study examined the association between childhood trauma and stress-related vulnerability factors in a healthy adult sample (n = 79; 68% female, mean age = 27.5, SD = 6.5). Emotion regulation difficulties were examined as a potential mediator. Participants completed baseline laboratory assessments of reported childhood trauma, emotion regulation difficulties, prior month sleep quality, baseline impedance cardiography and behavioural tests of executive functioning (EF) and a three-day experience sampling assessment protocol that included sleep diary, reported and objective pre-sleep arousal, daily hassles and reported EF difficulties. Reported history of childhood abuse was significantly associated with difficulties in emotion regulation, self-report and objective pre-sleep arousal, diary-assessed sleep quality, daily hassles and reported EF difficulties. Reported history of childhood neglect was associated with greater pre-sleep arousal and poorer EF-behavioural control. Emotion regulation difficulties mediated the relationship between childhood abuse and reported pre-sleep arousal, daily hassles and reported EF difficulties. In conclusion, history of childhood trauma is associated with a variety of stress-related vulnerability factors in healthy adults that may be viable early intervention targets.

Abstract
OBJECTIVE To study the moderated mediation for attention deficit/hyperactivity disorder (ADHD) with the symptoms of anxiety in children. METHODS A total of 12 271 students were included with an average age of 8.9±1.9 years, including 6 743 male students and 5 508 female students, and 20 students with missing data on gender. Child psychological trauma questionnaires (parents version) and Conners questionnaires (parent version) were completed by the parents of primary school students. The data was studied by univariate analysis, multivariate analysis and moderated mediation analysis. RESULTS The results of the univariate analysis showed that in all subjects, boys, and girls, the scores of hyperactivity index and childhood trauma were positively correlated with the score of anxiety (P<0.01), and ADHD and childhood trauma positively predicted anxiety disorder (P<0.001). The results of the multivariate analysis showed that in all subjects, boys, and girls, the scores of hyperactivity index (ADHD symptoms) and childhood trauma positively predicted the score of anxiety (P<0.001), and both ADHD and childhood trauma positively predicted anxiety disorder (P<0.001). The results of the moderated mediation analysis showed that childhood trauma was a mediating factor for the relationship between hyperactivity index and anxiety index in boys and girls (P<0.05), and sex moderated the relationship between hyperactivity index and anxiety index (P<0.001). CONCLUSIONS ADHD symptoms/ADHD are closely associated with anxiety symptoms/anxiety disorder. Childhood trauma exerts a mediating effect on the relationship between ADHD symptoms and anxiety symptoms, and sex moderates the relationship between ADHD symptoms and anxiety symptoms.

Abstract
Childhood assaultive trauma exposure is linked to less cortical thickness. Cortical thickness in prefrontal regions is inversely associated with aggression. Prefrontal thickness mediated the link between trauma exposure and aggression.
Although the link between childhood maltreatment and violence perpetration in adulthood (i.e., the “cycle of violence”) is well-documented, the neural mechanisms driving these processes remain relatively unknown. The objectives of this study were to investigate whether cortical thickness in adulthood varies as a function of childhood assaultive trauma exposure and whether such neurobiological markers of early trauma relate to the perpetration of aggression across the lifespan. In a sample of 138 ethnically-diverse men and women, whole-brain analysis of the cortical mantle revealed that individuals with exposure to assaultive trauma before age 13 had less cortical thickness in two clusters that survived multiple comparison correction: a region that peaked in the left lateral orbitofrontal cortex (OFC) and a region peaking in the right pericalcarine cortex. Diminished cortical thickness in the left OFC cluster was, in turn, associated with greater physical aggression, and mediation analysis revealed that reductions in cortical thickness in this left prefrontal region partially accounted for the association between exposure to childhood assaultive trauma and lifetime perpetration of aggression in adulthood. Findings extend previous investigations into the morphological correlates of early assaultive trauma by implicating reductions in cortical thickness as a potential mechanism linking early violence exposure to violence perpetration that extends into adulthood.

Abstract
MicroRNAs (miRNAs), one of the major small non-coding RNA classes, have been proposed as regulatory molecules in neurodevelopment and stress response. Although alterations in miRNAs profiles have been implicated in several psychiatric and neurodevelopmental disorders, the contribution of individual miRNAs in brain development and function is still unknown. Recent studies have identified miR-19 as a key regulator of brain trajectories, since it drives the differentiation of neural stem cells into mature neurons. However, no findings are available on how vulnerability factors for these disorders, such as early life stress (ELS), can modulate the expression of miR-19 and its target genes. To reach our aim, we investigated miR-19 modulation in human hippocampal progenitor stem cells (HPCs) treated with cortisol during 3 days of proliferation and harvested immediately after the end of the treatment or after 20 days of differentiation into mature neurons. We also analyzed the long-term expression changes of miR-19 and of its validated target genes, involved in neurodevelopment and inflammation, in the hippocampus of adult rats exposed or not to prenatal stress (PNS). Interestingly, we observed a significant downregulation of miR-19 levels both in proliferating (FC = −1.59, p-value = 0.022 for miR-19a; FC = −1.79, p-value = 0.016 for miR-19b) as well as differentiated HPCs (FC = −1.28, p-value = 0.065 for miR-19a; FC = −1.75, p-value = 0.047 for miR-19b) treated with cortisol. Similarly, we found a long-term decrease of miR-19 levels in the hippocampus of adult PNS rats (FC = −1.35, p-value = 0.025 for miR-19a; FC = −1.43, p-value = 0.032 for miR-19b). Among all the validated target genes, we observed a significant increase of NRCAM (FC = 1.20, p-value = 0.027), IL4R (FC = 1.26, p-value = 0.046), and RAPGEF2 (FC = 1.23, p-value = 0.020).We suggest that ELS can cause a long-term downregulation of miR-19 levels, which may be responsible of alterations in neurodevelopmental pathways and in immune/inflammatory processes, leading to an enhanced risk for mental disorders later in life. Intervention strategies targeting miR-19 may prevent alterations in these pathways, reducing the ELS-related effects.

Abstract
Although anxiety disorders are among the most prevalent of psychiatric disorders, childhood trauma-related studies seldom consider anxiety proneness as distinct aetiological contributor. We aimed to distinguish between trauma- and anxiety-associated physiological profiles. South African adolescent volunteers were categorised for trauma exposure (CTQ, mean score 39±11) and anxiety proneness (AP)(CASI, mean score 37±7, STAI-T, mean score 41±8). Circulating hormone and leukocyte glucocorticoid receptor levels, as well as leukocyte functional capacity, were assessed. AP was associated with lower DHEAs (P<0.05) and higher leukocyte GR expression (P<0.05). DHEAs was also negatively correlated with anxiety sensitivity (CASI, P<0.05). In conclusion, AP may have more predictive power than trauma in terms of health profile. Increased glucocorticoid sensitivity previously reported after trauma, may be a unique function of anxiety and not trauma exposure per se. DHEAs concentration was identified as potentially useful marker for monitoring progressive changes in HPA-axis sensitivity and correlated with psychological measures of anxiety.

Abstract
Deleterious effects of adverse childhood experiences (ACE) on human brain volume are widely reported. First evidence points to differential effects of ACE on brain volume in terms of timing of ACE. Upcoming studies additionally point towards the impact of different types (i.e., neglect and abuse) of ACE in terms of timing. The current study aimed to investigate the correlation between retrospectively reported severity of type (i.e., the extent to which subjects were exposed to abuse and/or neglect, respectively) and timing of ACE on female brain volume in a sample of prolonged traumatized subjects. A female sample with ACE (N = 68) underwent structural magnetic resonance imaging and a structured interview exploring the severity of ACE from age 3 up to 17 using the “Maltreatment and Abuse Chronology of Exposure” (MACE). Random forest regression with conditional interference trees was applied to assess the impact of ACE severity as well as the severity of ACE type, (i.e. to what extent individuals were exposed to neglect and/or abuse) at certain ages on pre-defined regions of interest such as the amygdala, hippocampus, and anterior cingulate (ACC) volume. Analyses revealed differential type and timing-specific effects of ACE on stress sensitive brain structures: Amygdala and hippocampal volume were affected by ACE severity during a period covering preadolescence and early adolescence. Crucially, this effect was driven by the severity of neglect.

Abstract
Executive functions are considered essential for effective navigation in the social world. Parental responsiveness is a critical ingredient for normative social development and, as such, may be connected with the development of executive functions. Disruption of this development may, in turn, lead to maladaptive and antisocial behaviors. The purpose of this study was to evaluate the nature of the connections among perceived patterns of caregiving experienced in childhood, executive functions, and antisocial behaviors in at-risk adolescents. Seventy-one adolescent boys were recruited from two high-schools for adolescents who were not deemed suitable for regular schooling due to behavioral and emotional issues. Executive functions were tested using a computer-administered neuropsychological battery (CANTAB), and maternal parenting experiences and antisocial behaviors were assessed using retrospective and current questionnaires. Structural equation modeling (SEM) approach was employed to examine whether executive functions mediated the relationship between children's perceived patterns of maternal care and subsequent development of antisocial behaviors. Although maternal care had a significant direct effect on executive function (standardized coefficient = .49, p = .03) and antisocial behavior (standardized coefficient = .53, p = .05), SEM demonstrated no mediating relationships among these variables. Instead, maternal care predicted unique variance in both executive functions (standardized coefficient = .61, p = .02) and antisocial behavior (standardized coefficient = .51, p = .05). This study suggests a link between the experience of childhood caregiving and adolescent executive functions and delinquency and highlights the importance of early parenting interventions to aid executive function development. Such early interventions could potentially enhance long-term pro-social behavior.

Abstract
Substance use among women is a major public health concern. This review article takes a developmental-relational approach to examine processes through which early relational trauma and violence in relationships may lead to substance use. We examine how early exposure to violence in relationships can impact neurological development, specifically through interference with physiological mechanisms (e.g., the hypothalamic-pituitary-adrenal axis), brain structure and functioning (e.g., the hippocampus and prefrontal cortex), and neuropsychological development (e.g., executive functioning and emotion regulation) across the lifespan. Further, we discuss the impact of exposure to violence on the development of relational capacity, including attachment, internal working models, and subsequent interpersonal relationships across the lifespan, and how these developmental pathways can lead to continued problematic substance use in women.

Addressing the Impact of Interpersonal Violence in Women Who Struggle with Substance Use Through Developmental-Relational Strategies in a Community Program. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16214197. [PMID: 31671516 PMCID: PMC6862384 DOI: 10.3390/ijerph16214197] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Revised: 10/19/2019] [Accepted: 10/26/2019] [Indexed: 11/25/2022]
Abstract
From a developmental–relational framework, substance use in women can be understood as relating to early experiences of violence in relationships and across development. This article uses a developmental-relational approach to outline specific strategies that can be used by service providers and to guide interventions for women with substance use issues. By reviewing research and clinical work with women attending a community-based prevention and early intervention program, we describe how specific components of programming can target the developmental and intergenerational pathway between experiences of violence in relationships and substance use. We include the voices of women who attended the program to support the strategies discussed. Specifically, these strategies address the impact of interpersonal violence on substance use by promoting the process of repair and reintegration for women whose neurological development, sense of self, and capacity to form relationships have been significantly impacted by experiences of violence in relationships.

J Trauma Stress 2019; 32:753-763. [PMID: 31441982 DOI: 10.1002/jts.22442] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 04/02/2019] [Accepted: 04/07/2019] [Indexed: 01/08/2023]
Abstract
Trauma screening is an important element for providing trauma-informed services to youth in residential care. Unfortunately, lack of time and resources may deter clinicians from conducting trauma screening at intake. This study tested the psychometric properties of the Brief Trauma Symptom Screen for Youth (BTSSY), which could be used during intake into residential care. Participants included 572 youth, ages 10-18 years (M = 14.28 years, SD = 2.31), of whom 58.9% were boys, 78.7% were Caucasian, 51.7% were youth receiving services in residential care, 15.6% were youth with clinical needs, and 32.7% were typically developing youth from the local community. Participants completed the BTSSY; other questionnaires of psychopathology, childhood maltreatment, and symptomology of posttraumatic stress disorder (PTSD); and diagnostic interviews, which were conducted by licensed psychiatrists. The total BTSSY score had a good composite reliability (CR) of .80 and was valid based on a significant positive correlation, r = .64, with the UCLA PTSD-Reaction Index. The BTSSY score was also fair, area under the curve = .75, at detecting a diagnosis of PTSD from a psychiatrist. Significant group differences in the BTSSY scores were found between youth with a diagnosis of PTSD and the other two groups, with moderate-to-large effect sizes, ds = 0.73-1.22. Preliminary results indicated the BTSSY may be a useful screening tool for identifying youth at residential care intake who may need additional assessment for PTSD. Limitations and implications for future research and practice are discussed.
