Trauma-Based Sexually Dimorphic Changes in the Connectome and Its Association with Central Sensitization Syndromes—A Systematic Review

Background/Objectives: Chronic pain syndromes pose a significant global health challenge to patients and physicians with a complex relationship of biological and psychosocial factors that are only partly understood. Emerging research suggests an association between prenatal and childhood adversity and the development of somatic syndromes, particularly in females. This study aims to explore the relationship between sexual dimorphic epigenetic changes in the connectome and prenatal and early life adversity (ELA). Methods: A review of the existing literature was conducted, examining studies utilizing MRI to identify critical periods of environmental influence on neural phenotypes. Results: The findings indicate a significant association between prenatal and childhood adversity and the emergence of central sensitization syndromes, particularly among females. Notably, alterations in grey matter volume and neural connectivity patterns were observed, suggesting that early adverse experiences can influence pain signaling mechanisms. Conclusions: Understanding the role of sex differences in brain circuitry is crucial for developing personalized pain management strategies. This study highlights the importance of considering both biological and psychosocial factors in addressing chronic pain, as interventions based predominantly on male subjects may be less effective for females. Further research is warranted to explore these differences and refine therapeutic approaches.

The mediating role of neuroticism and anxiety sensitivity in the relationship between childhood trauma and panic disorder severity.

Despite advancements in understanding panic disorder (PD), its etiology and pathogenesis remain elusive, particularly concerning the influence of psychosocial factors. This study aims to explore the mediating roles of neuroticism and anxiety sensitivity (AS) in the relationship between childhood trauma and PD severity. We conducted a cross-sectional analysis involving 84 individuals diagnosed with PD and 112 age- and gender-matched healthy controls (HC). Childhood trauma was assessed using the validated Childhood Trauma Questionnaire (CTQ), while anxiety sensitivity levels were measured using the Anxiety Sensitivity Index-3 (ASI-3). Neuroticism was evaluated using the Chinese Big Five Personality Inventory (CBF-PI-B). The severity of PD was determined using the Panic Disorder Severity Scale (PDSS). Statistical analysis encompassed both correlation and mediation techniques to thoroughly examine the relationships among childhood trauma, neuroticism, AS, and PD severity. Individuals with PD exhibited significantly higher CTQ, ASI-3, and neuroticism scores compared to HC (all P<0.05). Within the PD group, strong positive correlations were found between CTQ scores, ASI-3 scores, neuroticism levels, and PDSS scores, with correlation coefficients ranging from 0.336 to 0.504 (all P<0.001). Additionally, our results indicated that neuroticism and AS acted as mediating factors in the relationship between childhood trauma and the severity of PD, with the 95% confidence interval for the indirect effects ranging from 0.028 to 0.116. This study highlights that PD patients exhibit significantly higher levels of childhood trauma, neuroticism, and AS compared to HC. Furthermore, childhood trauma indirectly influences PD severity through a chain mediation involving neuroticism and AS. These findings suggest the importance of psychological factors in moderating the impact of early adverse experiences on the development and progression of PD.

Early life social conditions and adverse experiences are associated with childhood BMI and perceived overeating.

Early life socioeconomic disadvantage and adverse experiences may lead to overeating, which is in turn associated with increased body mass index (BMI). However, recent evidence indicated that the association between childhood BMI and overeating might be bidirectional. This bidirectionality prompts the need for further investigation of early life predictors of BMI in childhood. To longitudinally assess the directionality of the association between childhood BMI and perceived overeating and to investigate their antecedent early life predictors. The sample included data from 5151 children from the ELSPAC study, collected between 18 months and 11 years of child age. The outcomes were child BMI and mother-reported overeating, assessed at the age of 3, 5, 7 and 11 years. Predictors included maternal BMI, maternal education, single parenthood, financial difficulties and adverse childhood experiences (ACEs) reported by parents and paediatricians. The random intercept cross-lagged panel model was applied. The mean child's BMI at age 3 was 15.59 kg/m2 and increased to 17.86 kg/m2 at age 11. The percentage of parent-reported overeating increased in the following period, from about 12% at age 3 to 17% at age 11. The results showed temporal stability in perceived overeating and BMI, with a bidirectional relationship strengthening over time. The child's BMI was associated with maternal BMI. Maternal BMI was positively associated with child-perceived overeating, but a stronger effect was found for ACEs. ACEs mediated the impact of maternal education, financial difficulties and single parenthood on overeating. We observed stable bidirectional associations between BMI and perceived overeating. The results indicated two main pathways: one linked to maternal BMI and early childhood BMI increase followed by perceived overeating and the second associated with ACEs mediating the effect of early childhood social factors on perceived overeating, leading to gradual BMI gain.

An adaptive dynamical system model for development of schizophrenia: Epigenetics and false memories

This paper introduces a fifth-order adaptive dynamical system model represented as a self-modelling network model to understand the role of epigenetic factors in developing schizophrenia, particularly about the occurrence of false memories. Schizophrenia, affecting a significant portion of the global population, presents complex challenges due to its symptoms across cognitive, emotional, and social domains. Central to this paper is the exploration of epigenetic influences on the development of schizophrenia, with a focus on how these epigenetic factors contribute to the generation of false memories, a notable symptom of the disorder. The model assumes that early adverse experiences significantly affect hippocampal development, which is crucial for memory processes. By employing a fifth-order adaptive dynamical system model represented as a self-modelling network, this paper examines the intricate dynamics between genetic predispositions, environmental factors, and epigenetic modifications in schizophrenia. The model’s sophistication allows for a nuanced understanding of the gene-environment interactions, particularly highlighting the role of early-life trauma in shaping lifelong cognitive outcomes. This approach offers a comprehensive framework for analyzing the multifaceted nature of schizophrenia, contributing to a deeper understanding of its etiology and progression.

Primary and secondary trauma in adoptive parents.

Secondary trauma is recognised as one of the negative effects for professionals working with people that have experienced trauma. Research has demonstrated secondary trauma in foster carers but little research has explored trauma symptoms within adoptive parents, facing the emotional impact of parenting a child with adverse early experiences. This study aimed to document the rates of primary and secondary trauma symptoms in adoptive parents. It further explores the association between the extent of current behavioural and emotional challenges and the extent of the child's pre-adoption adverse experiences in predicting parental trauma responses. 190 adoptive parents completed an online survey including self-report measures of primary and secondary trauma. Almost one fifth of adoptive parents exhibited primary trauma scores of clinical concern; with 10% reaching the threshold for a probable diagnosis of PTSD. Participants also reported significantly higher levels of secondary trauma and burnout, and significantly lower levels of compassion satisfaction than population norms. The current behavioural and emotional challenges, including child-to-parent violence, predicted higher trauma scores more so than the extent of their child's past adverse experiences. The findings have clinical implications for identifying trauma symptoms within adoptive parents and wider implications for how we understand secondary and primary trauma. They further highlight the importance of firstly addressing current child behaviour, including child-to-parent violence when treating trauma symptoms. Limitations of this study and recommendations for further research are discussed.

Being insulted by parents is the most severe early adverse experience of anxiety in adulthood

IntroductionWhich adverse childhood experiences are causally associated with anxiety in adulthood is unclear. Sensitive Period Model states that early adverse experiences can influence anxiety levels in adulthood. However, it remains unknown which adverse experience is the most important early adverse factor for anxiety in adulthood, and whether early alleviation or aggravation of this adverse experience predicts a decrease or increase in anxiety levels in adulthood. MethodsA national cross-sectional survey was conducted from 20 June 2023 to 31 August 2023, with a total of 30,054 adults aged 18 years or older recruited on questionnaires that completed the Adverse Childhood Experiences Scale and Generalised Anxiety Disorder Scale. We used network analysis and computer simulation techniques to simulate aggravating and simulate alleviating interventions to observe changes in anxiety levels to identify early adverse experiences causally associated with anxiety levels in adulthood. ResultsThe results of both the network analysis and the nodeIdentifyR algorithm (NIRA) indicated that in the Adverse Childhood Experiences-Anxiety Network (ACE-GAD Network), being cursed and insulted (CUR) by parents in childhood was the most severe early adverse experience contributing to anxiety in adulthood. In particular, simulated aggravation interventions targeting CUR in young and middle-aged adults resulted in significantly higher levels of anxiety in adulthood. ConclusionsThis suggests that preventing verbal curses or insults in childhood can be an early preventive measure for future anxiety interventions. This study has important theoretical and practical implications, providing new insights for early prevention of anxiety and family education.

The Reward Positivity Mediates the Association Between Adverse Childhood Experiences and Anhedonia in Young Adults With Drug-Naïve Major Depressive Disorder

BackgroundCurrent clinical studies have indicated that major depressive disorder (MDD) concurrent with adverse childhood experiences (ACEs) is associated with greater anhedonia. However, little is known about whether the change in reward sensitivity among young individuals with MDD and ACEs is related to anhedonia. MethodsWe evaluated anhedonia and ACEs in 86 patients with MDD (31 with no or 1 ACE and 55 with 2 or more ACEs) and 44 healthy control participants. Then, participants completed the Iowa Gambling Task during electroencephalography to measure the reward positivity (RewP) and its difference (ΔRewP; gains minus losses). Furthermore, we constructed a mediation model to assess whether aberrant ΔRewP mediated the relationship between ACEs and anhedonia. ResultsCompared with healthy control participants and MDD patients with no or 1 ACE, MDD patients with 2 or more ACEs had the most severe symptoms of anhedonia and impaired decision making and showed significantly reduced reward sensitivity (most blunted ΔRewP). More importantly, ΔRewP mediated the relationship between ACEs and anhedonia in MDD. ConclusionsWe found that the ΔRewP partially mediated the association between ACEs and anhedonia in patients with MDD, which provides evidence for the neurobiological basis of abnormal changes in the reward system in MDD individuals with early adverse experiences.

Defining and distinguishing early life stress, trauma, adversity, toxic and chronic stress and allostatic load: a descriptive review.

Various concepts are used to study the impact of stress on childhood development. These concepts are often used inconsistently or interchangeably. Our main objectives were to determine how selected stress concepts (chronic stress, toxic stress, allostatic load, early life stress, childhood adversity, childhood trauma and adverse childhood experiences; ACEs) are defined, operationalized and described, and to provide a theoretical context to aid the choice for a preferred concept in public health research. For this descriptive review, we systematically searched for literature published before 4 August 2021, on PubMed, Embase and PsycInfo. Two independent reviewers included studies. Exclusion criteria were: no systematic review, not peer reviewed, not published in English, selected stress concepts were no predetermined variable or a substantial topic in the discussion, full text was unobtainable or study described non-human or non-childhood populations. Data extraction forms were used. Descriptives were gathered, publication fields were identified through Journal Citation Reports categories, and verbatim descriptions were ordered in text and Venn diagrams. Of 264 screened studies, 124 were included. ACEs, childhood adversity and childhood trauma were used most. ACEs were the main concept used most frequently (47.6%). A total of 11 of 14 public and environmental health journals used ACEs. All concepts refer to prolonged, repeated, interpersonal stress from 0 to 18 years, that can alter physiological systems. Four concepts were stressor oriented, two concepts focused on stress response and effect and one on the state of challenged homeostasis. ACEs seem most fitting for public health setting, due to their operationalizability, large set of core experiences and widespread use.

The interplay between borderline personality disorder and oxytocin: a systematic narrative review on possible contribution and treatment options.

Borderline personality disorder (BPD) is a complex mental health condition marked by instability in mood, relationships, self-image, and behavior. Individuals with BPD often struggle with intense emotions, impulsivity, and maintaining stable relationships. Oxytocin, known as the "love hormone" or "bonding hormone," plays a crucial role in social bonding, trust, empathy, and emotional regulation and its dysregulation may contribute to BPD difficulties. This systematic review aims to analyze existing literature, examining the intricate interplay and encouraging future research and treatment strategies. A systematic search of Literature in PubMed, Embase and Psychinfo, without any language or time restriction, was performed until March 2024 combining thesaurus and free-search indexing terms related to "borderline personality disorder" and "oxytocin", producing 310 results (77 in PubMed, 166 in Embase and 67 in Psychinfo). Ninety-four full texts were analyzed, and 70 articles were included in qualitative analysis. Oxytocin may influence attachment styles, parental behaviors, and stress responses, particularly in individuals with a history of childhood trauma. The interaction between oxytocin, genetics, early life experiences, and environmental factors contributes to the complexity of BPD. Genetic variations in the oxytocin receptor gene may influence social and emotional abilities and contribute to the development of psychopathology. Additionally, early adverse experiences, such as childhood maltreatment, can alter oxytocin functioning, impacting social cognition and emotional regulation.However, oxytocin's role in BPD treatment remains uncertain, with some studies suggesting potential benefits for specific symptoms like social threat avoidance, while others indicate adverse effects on nonverbal behavior and mentalizing. Understanding oxytocin's role in BPD offers insights into potential therapeutic interventions. While oxytocin-based treatments may hold promise for addressing specific symptoms, further research is needed.

Analysis of the life course effects of the disability dilemma among rural older adults in China.

To analyse whether the accumulation of early adverse experiences among individuals of different generations has an impact on disabilities and evaluate the cumulative effects of disadvantages in rural older adults in China. A Binary Logit Model was used to analyse the life course effects of the disability dilemma among rural older adults. Regarding Activities of Daily Life (ADLs), there was no significant difference between older adults that experienced 1 adverse events and the control group. The probability of older adults experiencing difficulties in 2, 3, 4, or more types of ADLs was 1.486 times, 2.173 times, and 3.048 times higher than that of the control group, respectively. Regarding Instrumental Activities of Daily Life (IADLs), there was no significant difference between the population that experienced 1 or 2 adverse events and the control group. The probability of experiencing difficulties in 3, 4, or more types of IADLs was 1.527 times and 1.937 times higher than that of the control group, respectively. Early adverse events had a cumulative disadvantageous effect on disability in older adults. The longer the duration of adverse experiences, the higher the risk of disability in old age. Education had a significant mitigating effect on health risks. Pay attention to early factors in the life course, strengthen the promotion of health prevention concepts, and pay attention to the moderating and relieving effects of education on health. We should also gradually improve the rural disability care system and family health security capabilities in China's rural areas.

Role of tactile stimulation during the preweaning period on the development of the peripheral sensory sural (SU) nerve in adult artificially reared female rat.

Maternal deprivation, as a result of the artificial rearing (AR) paradigm, disturbs electrophysiological and histological characteristics of the peripheral sensory sural (SU) nerve of infant and adult male rats. Such changes are prevented by providing tactile or social stimulation during isolation. AR also affects the female rat's brain and behavior; however, it is unknown whether this early adverse experience also alters their SU nerve development or if tactile stimulation might prevent these possible developmental effects. To assess these possibilities, the electrophysiological and histological characteristics of the SU nerve from adult diestrus AR female rats that: (i) received no tactile stimulation (AR group), (ii) received tactile stimulation in the anogenital and body area (AR-Tactile group), or (iii) were mother reared (MR group) were determined. We found that the amplitude, but not the area, of the evoked compound action potential response in SU nerves of AR rats was lower than those of SU nerves of MR female rats. Tactile stimulation prevented these effects. Additionally, we found a reduction in the outer diameter and myelin thickness of axons, as well as a large proportion of axons with low myelin thickness in nerves of AR rats compared to the nerves of the MR and AR-Tactile groups of rats; however, tactile stimulation only partially prevented these effects. Our data indicate that maternal deprivation disturbs the development of sensory SU nerves in female rats, whereas tactile stimulation partially prevents the changes generated by AR. Considering that our previous studies have shown more severe effects of AR on male SU nerve development, we suggest that sex-associated factors may be involved in these processes.

The relationship between childhood adversity and sleep quality among rural older adults in China: the mediating role of anxiety and negative coping

BackgroundStudies have revealed the effects of childhood adversity, anxiety, and negative coping on sleep quality in older adults, but few studies have focused on the association between childhood adversity and sleep quality in rural older adults and the potential mechanisms of this influence. In this study, we aim to evaluate sleep quality in rural older adults, analyze the impact of adverse early experiences on their sleep quality, and explore whether anxiety and negative coping mediate this relationship.MethodsData were derived from a large cross-sectional study conducted in Deyang City, China, which recruited 6,318 people aged 65 years and older. After excluding non-agricultural household registration and lack of key information, a total of 3,873 rural older adults were included in the analysis. Structural equation modelling (SEM) was used to analyze the relationship between childhood adversity and sleep quality, and the mediating role of anxiety and negative coping.ResultsApproximately 48.15% of rural older adults had poor sleep quality, and older adults who were women, less educated, widowed, or living alone or had chronic illnesses had poorer sleep quality. Through structural equation model fitting, the total effect value of childhood adversity on sleep quality was 0.208 (95% CI: 0.146, 0.270), with a direct effect value of 0.066 (95% CI: 0.006, 0.130), accounting for 31.73% of the total effect; the total indirect effect value was 0.142 (95% CI: 0.119, 0.170), accounting for 68.27% of the total effect. The mediating effects of childhood adversity on sleep quality through anxiety and negative coping were significant, with effect values of 0.096 (95% CI: 0.078, 0.119) and 0.024 (95% CI: 0.014, 0.037), respectively. The chain mediating effect of anxiety and negative coping between childhood adversity and sleep quality was also significant, with an effect value of 0.022 (95% CI: 0.017, 0.028).ConclusionsAnxiety and negative coping were important mediating factors for rural older adult’s childhood adversity and sleep quality. This suggests that managing anxiety and negative coping in older adults may mitigate the negative effects of childhood adversity on sleep quality.

The Types of Psychosocial Factors Associated with Suicidality Outcomes for People Living with Bipolar Disorder: A Scoping Review.

Bipolar Disorder is associated with high rates of suicidal thoughts, behaviors, and outcomes, yet the lived experience of suicidality and Bipolar Disorder is not particularly well understood. Understanding the role of psychosocial aetiologies in suicidality outcomes for those living with Bipolar Disorder is key for developing appropriately targeted interventions focusing on factors that are amenable to change. In line with PRISMA guidance, we conducted a scoping review to identify the types of psychosocial factors studied in relation to the experience of suicidality for people living with Bipolar Disorder diagnoses. Systematic literature searches identified a sample of 166 articles from which key study data were extracted and charted. A narrative synthesis of the reviewed literature is presented ordered by the factors investigated across studies, a frequency count of the types of psychological/social aetiologies studied, and a brief overview of the key findings for each aetiology. Most of the identified literature took the form of quantitative cross-sectional studies, with only one qualitative study and 18 quantitative prospective studies. The most studied aetiologies were trauma (specifically early adverse experiences and childhood traumas) and stressful life events, impulsivity (primarily subjective self-reported trait impulsivity), social support and functioning, and personality/temperament factors. Only six studies in the final sample reported basing their research questions and/or hypotheses on an explicit theoretical model of suicide. The literature was primarily focused on using self-report measurements of key aetiologies and on factors which lead to worsened suicidality rather than focusing on potentially protective or buffering factors. Future research needs to better justify the aetiologies investigated in relation to suicidality outcomes for people living with Bipolar Disorder, including a firmer basis in theory and hypothesis testing, more prospective designs, and the use of alternative assessments of psychosocial aetiologies in addition to self-report questionnaires.

Is trauma research neglecting neurodiverse populations? A systematic review and meta-analysis of the prevalence ACEs in adults with autistic traits

PurposeThe prevalence of exposure to adversity is elevated in autistic populations, compared to neurotypical peers. Despite this, the frequency and nature of early adverse experiences are not well understood in autistic adults, with several underlying methodological limitations in the available literature. The purpose of this study is to systematically synthesise and analyse the prevalence of childhood adversity in this marginalised population, in accordance with the adverse childhood experiences (ACEs) framework.Design/methodology/approachPeer-reviewed empirical research articles were systematically searched for from electronic databases and screened against established inclusion criteria. Pooled prevalence rates for individual ACE types were calculated.FindingsFour papers were included (N = 732), all of which used a predominantly or exclusively female sample. Only sexual abuse was reported in all papers, with a pooled prevalence rate of 38%. Physical abuse and emotional abuse were less frequently explored, with two papers reporting on these ACEs, though obtained comparable and higher pooled prevalence rates (39% and 49%, respectively). Pooled prevalence rates could be calculated for neither neglect nor “household” ACEs because of insufficient data. The limited state of the evidence, in conjunction with high levels of heterogeneity and poor sample representativeness found, positions the ACEs of autistic adults as a critical research priority.Originality/valueTo the best of the authors’ knowledge, this study is the first to systematically synthesise the prevalence of early childhood adversities, as conceptualised in accordance with the ACEs framework, in adults with autistic traits.

Foster Care Leads to Lower Irritability Among Adolescents with a History of Early Psychosocial Deprivation.

Irritability reflects a propensity for frustration and anger, and is a transdiagnostic symptom of both externalizing and internalizing psychopathology. While early adverse experiences are associated with higher levels of irritability, experiences of early psychosocial deprivation and whether family-based placements can mitigate the impact on subsequent irritability, remain underexplored. The current study examined irritability in 107 16-year-olds with a history of institutional care from a randomized controlled trial of foster care as an alternative to institutional care and 49 community comparison children. At age 16 years, irritability was assessed using parent- and self-report forms of the Affective Reactivity Index. Compared to community adolescents, those with a history of institutional care exhibited significantly elevated irritability levels. Among those who experienced institutional care, those randomized to foster care had lower levels of irritability compared to participants randomized to the care-as-usual group, and this effect persists after controlling for baseline negative emotionality. These findings suggest a causal link between high-quality foster care and lower irritability following psychosocial deprivation. Additionally, longer duration in institutional care and non-family placement at age 16 years were associated with higher levels of irritability, highlighting the role of caregiving in explaining variation in irritability in adolescence. Policies that support long-term, high-quality family placements for children without regular caregivers should be prioritized.

Adverse childhood experiences and insecure attachment: The indirect effects of dissociation and emotion regulation difficulties.

Difficulties with dissociation and emotion regulation are well-documented reactions to early adverse childhood experiences (ACEs). Although findings identify dissociation and emotion dysregulation as explaining the relationship between various forms of ACEs and adult psychopathology, less is known about their combined effect in the relationship between ACEs and insecure attachment in adulthood. This study examined the indirect effects of dissociation and emotion regulation difficulties in the relationship between early adverse experiences and insecure attachment traits. Participants (N = 260) completed an online questionnaire measuring ACEs, dissociation, emotion regulation difficulties, and anxious and avoidant attachment. Results indicated that, after controlling for mental health treatment, dissociation and emotion regulation difficulties explained the relationship between ACEs and insecure (anxious and avoidant) attachment. Emotion regulation difficulties were not a significant predictor of avoidant attachment. Findings provide support for greater research on mediating factors in the maintenance of insecure attachment across development and potential implications of dissociation and emotion regulation in clinical and nonclinical populations.

Early-Life Adversities Are Associated With Lower Expected Value Signaling in the Adult Brain

BackgroundEarly adverse experiences are assumed to affect fundamental processes of reward learning and decision making. However, computational neuroimaging studies investigating these circuits in the context of adversity are sparse and limited to studies conducted in adolescent samples, leaving the long-term effects unexplored. MethodsUsing data from a longitudinal birth cohort study (n = 156; 87 female), we investigated associations between adversities and computational markers of reward learning (i.e., expected value, prediction errors). At age 33 years, all participants completed a functional magnetic resonance imaging–based passive avoidance task. Psychopathology measures were collected at the time of functional magnetic resonance imaging investigation and during the COVID-19 pandemic. We applied a principal component analysis to capture common variations across 7 adversity measures. The resulting adversity factors (factor 1: postnatal psychosocial adversities and prenatal maternal smoking; factor 2: prenatal maternal stress and obstetric adversity; factor 3: lower maternal stimulation) were linked with psychopathology and neural responses in the core reward network using multiple regression analysis. ResultsWe found that the adversity dimension primarily informed by lower maternal stimulation was linked to lower expected value representation in the right putamen, right nucleus accumbens, and anterior cingulate cortex. Expected value encoding in the right nucleus accumbens further mediated the relationship between this adversity dimension and psychopathology and predicted higher withdrawn symptoms during the COVID-19 pandemic. ConclusionsOur results suggested that early adverse experiences in caregiver context might have a long-term disruptive effect on reward learning in reward-related brain regions, which can be associated with suboptimal decision making and thereby may increase the vulnerability of developing psychopathology.

GWAS in interaction with childhood traumas implicates novel variants and genes previously associated with suicide-related factors in the background of suicidal ideation

IntroductionAlthough suicide claims more lives than war and homicide, we still have no sufficient and effective methods either for its prediction or for its prevention. Our screening methods are laborous and subjective both on the side of the patient and on the side of the clinician. Understanding the genetic background of suicidal behaviour would help identify biomarkers for screening as well as pathways as potential targets for novel intervention and prevention approaches. However, in spite of a number of GWAS studies, results are few and rarely replicate, and generally accurate phenotyping and sufficient consideration of environmental stressors is also missing.ObjectivesIn our present study we performed a genome-wide analysis study for suicidal ideation in interaction with early childhood traumas in a deep-phenotyped general population sample.MethodsOur analysis used data from 1800 volunteers in the NewMood project. As outcome phenotype the suicidal ideation item of the Brief Symptom Inventory was used. A modified version of the Childhood Trauma Questionnaire was used to assess early adverse experiences. A genome-wide association analysis was performed with Plink 1.9, including a total of 3,474,641 variants after quality control steps, followed by genome-wide by environment interaction analyses. Our models included control variables for sex, age, and the top 10 genomic principal components. Functional annotation of SNPs was carried out using FUMA v1.5.6, gene-based tests were performed using MAGMA v1.08.Results7 SNPs met suggestive significance in main effect analyses, of which 2 reached genome-wide significance including rs79912020 (p=3.21E-10, β=0.746) and rs10236520 (p=1.71E-08, β=0.484), with no significant findings in gene-based tests. Interaction analyses with childhood adversities yielded 31 SNPs that met genome-wide significance, including rs7983955 (p=2.28E-11, β=0.182), rs141039461 (p=3.90E-11, β=0.0541), rs12692827 (p=3.69E-10, β=0.0612) as the top SNPs. In interaction with childhood adversities, 31 genes showed a significant association in gene-based tests, including RBFOX1 (p=1.09E-10), GRM7 (p=1.20E-10), MTCH1 (p=5.59E-09), and CDH13 (p=6.60E-09) as the most significant findings.ConclusionsOur results indicate several important novel SNPs associated with suicidal ideation when considered in interaction with the effect of childhood adversities. Furthermore, gene-based analyses replicate several genes playing a key role in central nervous system function such as GRM7 (encoding metabotropic glutamate receptor 7) or previously implicated in association with suicide (CDH13) or suicide-related factors such as aggression (RBFOX1).Funding: NAP2022-I-4/2022, K143391, 2019-2.1.7-ERA-NET-2020-00005, TKP2021-EGA-25Disclosure of InterestNone Declared

Adult self-reported childhood maltreatment types are associated with treatment satisfaction and alcohol relapse in patients with comorbid substance use and mental health disorders.

Individuals with comorbid substance use and mental health disorders (concurrent disorders; CD) report poor treatment outcomes, high prevalence of childhood maltreatment, and mostly negative experiences with treatment. No studies to date have examined childhood maltreatment and treatment outcomes in CD. This study investigated self-reported childhood maltreatment as it relates to treatment satisfaction and substance use relapse among CD patients. The 258 CD inpatients completed a self-report questionnaire package, comprising the Childhood Trauma Questionnaire and the Inpatient Consumer Survey (ICS). Childhood maltreatment was assessed according to five subtypes and self-perceived treatment satisfaction was rated across six ICS domains. Psychiatric diagnoses, substance use status and relapse data were retrieved via patient medical charts. Emotional neglect was associated with lower ratings across all ICS domains and physical neglect was associated with a lower rating for 'outcome of care'. Childhood sexual abuse was associated with a greater likelihood of alcohol relapse. No other relationships were statistically significant. The presence of childhood neglect (but not abuse) was more associated with overall treatment dissatisfaction, and sexual abuse alone increased the likelihood of alcohol relapse. These findings suggest some early adverse experiences in CD patients may increase negative experiences in treatment while others contribute to the risk of substance use. Broader longitudinal research is needed to examine the trajectory leading to negative outcomes. This is the first study to report differential patterns of association by type of childhood maltreatment on negative outcomes in treatment among CD patients.

The Impact of Adverse Childhood Experiences on Educational Outcomes in Adolescents

This paper's purpose is to review past literature on the effect of adverse childhood experiences on the educational outcomes of adolescent learners. Over the past few years, literature pieces through various researchers and writers have identified the great need to sensitize the reasons for the outcomes that adolescents get when they go through school. Most researchers have also focused on the possible solutions that could be used in addressing adolescents' different needs and challenges. One of the challenges that most researchers still need to identify is the early childhood experiences that adolescents go through even before they get to school. In this study, the researcher discussed academic effects related to early childhood adverse experiences. The family background and the different environmental issues that affect the mental state of adolescents as they grow up have been identified in this study as contributing factors to the adverse effects that lead to poor educational outcomes among adolescent learners. In addition, this study has found that adverse childhood experiences affect the students' learning outcomes by impacting different elements of the academic life of the learners. It influences the academic engagement of the learners, their level of achievement, and attendance to their studies in schools.
