Abstract
INTRODUCTION Early-life factors were reported to exert influence on the health condition of individuals in the long-term. However, limited research explored the connection between early-life factors and multimorbidity in later years. METHODS We utilized the data from the China Health and Retirement Longitudinal Study to assess this possible association in the present cross-sectional study. Multimorbidity was determined based on 14 common chronic diseases included in the study. Logistic regression was employed to examine the link between early-life factors and subsequent multimorbidity. RESULTS Out of 7,578 participants who met the inclusion criteria for analysis, 3,765 (49.68%) were females. The mean age was 68.25 ± 6.70 years. Participants who rated their health during childhood as average (odds ratio [OR] 0.78, 95% confidence interval [CI] 0.63-0.96) or better [OR 0.72, 95% CI 0.57-0.91] were significantly less likely to experience multimorbidity in older life. By contrast, experiencing violence from two of the family members was significantly associated with future multimorbidity (OR [95% CI], 1.29 [1.04-1.60]). A superior family financial situation was also negatively associated with multimorbidity, with average (OR [95% CI], 0.72 [0.63-0.83]) and better off than average (OR [95% CI], 0.76 [0.62-0.93]). DISCUSSION Individuals with poor health status, inferior family socioeconomic status, or experienced violence from family members in childhood were more likely to suffer from multimorbidity in later life. Enhanced social monitoring of potentially adverse conditions in youngsters and targeted interventions could help mitigate the progression of multimorbidity in later life.

Brain serotonin 1A receptor binding: relationship to peripheral blood DNA methylation, recent life stress and childhood adversity in unmedicated major depression. Br J Psychiatry 2023; 223:415-421. [PMID: 37395098 PMCID: PMC10514224 DOI: 10.1192/bjp.2023.13] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 12/19/2022] [Accepted: 01/12/2023] [Indexed: 07/04/2023]
Abstract
BACKGROUND Childhood and lifetime adversity may reduce brain serotonergic (5-HT) neurotransmission by epigenetic mechanisms. AIMS We tested the relationships of childhood adversity and recent stress to serotonin 1A (5-HT1A) receptor genotype, DNA methylation of this gene in peripheral blood monocytes and in vivo 5-HT1A receptor binding potential (BPF) determined by positron emission tomography (PET) in 13 a priori brain regions, in participants with major depressive disorder (MDD) and healthy volunteers (controls). METHOD Medication-free participants with MDD (n = 192: 110 female, 81 male, 1 other) and controls (n = 88: 48 female, 40 male) were interviewed about childhood adversity and recent stressors and genotyped for rs6295. DNA methylation was assayed at three upstream promoter sites (-1019, -1007, -681) of the 5-HT1A receptor gene. A subgroup (n = 119) had regional brain 5-HT1A receptor BPF quantified by PET. Multi-predictor models were used to test associations between diagnosis, recent stress, childhood adversity, genotype, methylation and BPF. RESULTS Recent stress correlated positively with blood monocyte methylation at the -681 CpG site, adjusted for diagnosis, and had positive and region-specific correlations with 5-HT1A BPF in participants with MDD, but not in controls. In participants with MDD, but not in controls, methylation at the -1007 CpG site had positive and region-specific correlations with binding potential. Childhood adversity was not associated with methylation or BPF in participants with MDD. CONCLUSIONS These findings support a model in which recent stress increases 5-HT1A receptor binding, via methylation of promoter sites, thus affecting MDD psychopathology.

Abstract
OBJECTIVE Women with HIV(WWH) are more likely to discontinue/change antiretroviral therapy(ART) due to side effects including neuropsychiatric symptoms. Efavirenz and integrase strand transfer inhibitors(INSTIs) are particularly concerning. We focused on these ART agents and neuropsychiatric symptoms in previously developed subgroups of WWH that differed on key sociodemographic factors as well as longitudinal behavioral and clinical profiles. WWH from the Women's Interagency HIV Study were included if they had ART data available, completed the Perceived Stress Scale-10 and PTSD Checklist-Civilian. Questionnaires were completed biannually beginning in 2008 through 2016. To examine ART-symptom associations, constrained continuation ratio model via penalized maximum likelihood were fit within 5 subgroups of WWH. Data from 1882 WWH contributed a total of 4598 observations. 353 women were previously defined as primarily having well-controlled HIV with vascular comorbidities, 463 with legacy effects(CD4 nadir < 250cells/mL), 274 aged ≤ 45 with hepatitis, 453 between 35-55 years, and 339 with poorly-controlled HIV/substance users. INSTIs, but not efavirenz, were associated with symptoms among key subgroups of WWH. Among those with HIV legacy effects, dolutegravir and elvitegravir were associated with greater stress/anxiety and avoidance symptoms(P's < 0.01); dolutegravir was also associated with greater re-experiencing symptoms(P = 0.005). Elvitegravir related to greater re-experiencing and hyperarousal among women with well-controlled HIV with vascular comorbidities(P's < 0.022). Raltegravir was associated with less hyperarousal, but only among women aged ≤ 45 years(P = 0.001). The adverse neuropsychiatric effects of INSTIs do not appear to be consistent across all WWH. Key characteristics (e.g., age, hepatitis positivity) may need consideration to fully weight the risk-benefit ratio of dolutegravir and elvitegravir in WWH.

Abstract
This study examines how formal education in biological and behavioral sciences may impact punishment intuitions (views on criminal sentencing, free will, responsibility, and dangerousness) in cases involving neurobiological evidence. In a survey experiment, we compared intuitions between biobehavioral science and non-science university graduates by presenting them with a baseline case without a neurobiological explanation for offending followed by one of two cases with a neurobiological explanation (described as either innate or acquired biological influences to offending). An ordinal logistic regression indicated that both science and non-science graduates selected significantly more severe punishments for the baseline case as compared to when an innate neurobiological explanation for offending was provided. However, across all cases, science graduates selected significantly less severe sentences than non-science graduates, and only science graduates' decisions were mediated by free will and responsibility attributions. Findings are discussed in relation to scientific understandings of behavior, the impact of science education on attitudes towards punishment, and potential criminal-legal implications.

Abstract
In the United States, a substantial proportion of the adult population (36% of women and 34% of men) from all socioeconomic and ethnic backgrounds report experiencing intimate partner violence (IPV) over the life course. Family risk factors have been linked to adolescent and young adult IPV involvement, yet few studies have examined the effect of multiple, co-occurring adverse childhood experiences (ACEs) in the stability and change of IPV behaviors over young adulthood-the period of highest risk for IPV. We investigated the relationship between the degree of ACE exposure and IPV victimization and perpetration at age 22 and two years later at age 24 among a sample of Hispanic young adults (N= 1,273) in Southern California. Negative binomial regression models compared the incident rate ratio (IRR) of past-year verbal and physical IPV victimization and perpetration of respondents with 1-3 ACE and with ≥4 ACE to their peers who reported no history of ACE cross-sectionally (age 22) and longitudinally (age 24). At age 22, participants with 1-3 and ≥4 ACE were overrepresented in all IPV behaviors and had higher IRRs of verbal and physical victimization and perpetration compared to their peers with no ACE. By age 24, respondents with a history of ≥4 ACE were at significantly greater risk for escalating IPV behaviors over this time period than their peers with 1-3 ACE and no ACE. These findings highlight the importance of investing in coordinated efforts to develop strategies that help young people cope with the downstream effects of early life adversity. Research should continue to identify what individual, community, and cultural assets that promote resilience and are promising foci of IPV prevention approaches among vulnerable populations.

Abstract
The COVID-19 pandemic may be experienced as traumatogenic and may fuel or exacerbate psychological distress and trauma-related symptoms. Based on trauma research, one might expect that survivors of childhood abuse would be susceptible to these negative outcomes during the pandemic, and that among this population a stronger relation between emotion regulation difficulties and symptomatology would be found. Aiming to explore these suppositions, an online survey was conducted among 710 Israeli adults. Of them, 370 were childhood abuse survivors. A history of childhood abuse, COVID-19-related stressors, overall psychological distress, and peritraumatic stress symptoms during the pandemic were assessed via self-report measures. Participants with a history of childhood abuse had elevated overall psychological distress as well as peritraumatic stress symptoms during the pandemic, compared to nonabused participants, above and beyond demographic characteristics and COVID-19-related stressors. Emotion regulation difficulties were related to elevated psychological distress and peritraumatic stress symptoms among both childhood abuse survivors and nonabused participants. Nonetheless, a history of childhood abuse moderated the relations between the emotion regulation difficulty of being unable to engage in goal-directed behaviors when distressed (on one hand) and mental outcomes (on the other): Although the associations between inability to engage in goal-directed behaviors, overall psychological distress, and peritraumatic stress symptoms were nonsignificant among nonabused participants, they were significant among childhood abuse survivors. The current findings suggest that a history of childhood abuse might be a risk factor for distress in the face of COVID-19, and that childhood abuse survivors would benefit from clinical interventions that promote emotion regulation skills during this ongoing global health crisis.

Comparing the Psychological Effects of Manikin-Based and Augmented Reality-Based Simulation Training: Within-Subjects Crossover Study. JMIR MEDICAL EDUCATION 2022; 8:e36447.

Abstract
BACKGROUND Patient simulators are an increasingly important part of medical training. They have been shown to be effective in teaching procedural skills, medical knowledge, and clinical decision-making. Recently, virtual and augmented reality simulators are being produced, but there is no research on whether these more realistic experiences cause problematic and greater stress responses as compared to standard manikin simulators. OBJECTIVE The purpose of this research is to examine the psychological and physiological effects of augmented reality (AR) in medical simulation training as compared to traditional manikin simulations. METHODS A within-subjects experimental design was used to assess the responses of medical students (N=89) as they completed simulated (using either manikin or AR) pediatric resuscitations. Baseline measures of psychological well-being, salivary cortisol, and galvanic skin response (GSR) were taken before the simulations began. Continuous GSR assessments throughout and after the simulations were captured along with follow-up measures of emotion and cortisol. Participants also wrote freely about their experience with each simulation, and narratives were coded for emotional word use. RESULTS Of the total 86 medical students who participated, 37 (43%) were male and 49 (57%) were female, with a mean age of 25.2 (SD 2.09, range 22-30) years and 24.7 (SD 2.08, range 23-36) years, respectively. GSR was higher in the manikin group adjusted for day, sex, and medications taken by the participants (AR-manikin: -0.11, 95% CI -0.18 to -0.03; P=.009). The difference in negative affect between simulation types was not statistically significant (AR-manikin: 0.41, 95% CI -0.72 to 1.53; P=.48). There was no statistically significant difference between simulation types in self-reported stress (AR-manikin: 0.53, 95% CI -2.35 to 3.42; P=.71) or simulation stress (AR-manikin: -2.17, 95% CI -6.94 to 2.59; P=.37). The difference in percentage of positive emotion words used to describe the experience was not statistically significant between simulation types, which were adjusted for day of experiment, sex of the participants, and total number of words used (AR-manikin: -4.0, 95% CI -0.91 to 0.10; P=.12). There was no statistically significant difference between simulation types in terms of the percentage of negative emotion words used to describe the experience (AR-manikin: -0.33, 95% CI -1.12 to 0.46; P=.41), simulation sickness (AR-manikin: 0.17, 95% CI -0.29 to 0.62; P=.47), or salivary cortisol (AR-manikin: 0.04, 95% CI -0.05 to 0.13; P=.41). Finally, preexisting levels of posttraumatic stress disorder, perceived stress, and reported depression were not tied to physiological responses to AR. CONCLUSIONS AR simulators elicited similar stress responses to currently used manikin-based simulators, and we did not find any evidence of AR simulators causing excessive stress to participants. Therefore, AR simulators are a promising tool to be used in medical training, which can provide more emotionally realistic scenarios without the risk of additional harm.

Abstract
BACKGROUND Individuals at clinical high-risk (CHR) for psychosis experience high rates of bullying. There is little research on the differences between CHR who did and did not experience bullying. However, there is evidence that bullying may be related to negative schemas and social impairment. OBJECTIVES To examine differences in core schemas, asocial and defeatist beliefs, and social functioning between those who did and did not report bullying experiences in a large sample of CHR individuals. We hypothesized that bullying in CHR youth would be associated with poorer social functioning, increased maladaptive beliefs, and negative core schemas. METHODS CHR participants (N = 203) were split into those who did and did not report experiencing bullying. The two groups were compared on demographic characteristics, social functioning, and belief variables, using the Brief Core Schemas Scale, the Asocial Beliefs Scale, the Defeatist Performance Attitudes Scale, and the First Episode Social Functioning Scale. RESULTS 72.9% reported experiencing bullying. These participants had greater severity of negative schemas about others and asocial and defeatist performance beliefs, and lower social functioning scores. CONCLUSIONS Prevalence of bullying among CHR participants is high. Bullying may be a risk factor for increased asocial and defeatist beliefs, negative core schemas, and poor social functioning. Targeting maladaptive schemas and beliefs during treatment may serve to improve functional outcomes in this group.

Abstract
Early life trauma is a risk factor for many mental disorders; however, there is a lack of research exploring early life trauma in Premenstrual Dysphoric Disorder (PMDD), a debilitating form of Premenstrual Syndrome (PMS). This descriptive study aimed to determine the prevalence of early life trauma in women with PMDD and characterise type and age of trauma experience. Data for 100 women diagnosed with PMDD was extracted from the Monash Alfred Women's Mental Health Clinic Database. Experience of early life trauma was subclassified into four types (Physical abuse, sexual abuse, emotional abuse and/or neglect) and four age groups (0-5, 6-10, 11-14 and/or 15-18 years old). Prevalence of early life trauma was calculated and compared with Australian population estimates. Eighty-three percent of women with PMDD had experienced early life trauma, with emotional abuse being the most common (71%). All types of trauma were more common amongst PMDD women than the general Australian population. Trauma prevalence was similar across the four age groups, ranging from 59 to 66%. Of note, 51.8% women experienced trauma across all age groups. Our results suggest a strong association between early life trauma and PMDD. Emotional abuse and/or chronic trauma across childhood may be most strongly associated with PMDD.

Abstract
BACKGROUND The mass terrorist attack in Nice, France, in July 2016 caused deaths and injuries in a local population, including children and adolescents. The Nice Pediatric Psychotrauma Center (NPPC) was opened to provide mental health care to the pediatric population (0-18 years) who experienced traumatic events. OBJECTIVES This study describes the specificity of the care pathway for young trauma victims, with an explanation of how the NPPC works during the first three years. METHODS In this retrospective study, we conducted quantitative and qualitative data collection about new and follow-up consultations, primary and comorbid diagnoses, and the kind of trauma (terrorist attack versus other kinds of trauma). Ethics approval was obtained from the local Ethics committee. RESULTS 866 children and adolescents were followed in the NPPC. We found a high rate of Post-Traumatic Stress Disorder (PTSD; 71%) in this population with a high rate of comorbidities (67%), mainly sleep disorders (34.7%) and mood and anxiety disorders (16.2%). A high number of children and adolescents impacted by the terrorist attack required follow-up consultations after exposure to the mass terrorist attack, the first care-seeking requests continued to occur three years later, although at a slower rate than in the first and second years. New consultations for other kinds of trauma were observed over time. DISCUSSION This study supports previous findings on the significant impact of mass trauma in the pediatric population showing even a higher level of PTSD and a high rate of comorbidities. This may be explained by the brutality of the traumatic event, particularly for this age group. The findings of this study have implications for early interventions and long-term care for children and adolescents to prevent the development of chronic PTSD into adulthood.

BEHAVIORAL SCIENCES & THE LAW 2021; 39:708-730.

Abstract
Justifications for punishment are generally grounded in retribution or consequentialism. Retribution is rooted in and legitimized by common sense notions of free will, claiming that offenders freely and rationally choose to commit a criminal act, and are therefore deserving of punishment. Consequentialism does not necessitate a reliance on a belief in free will, and views punishment as means to a valuable end. In recent years, neuroscientific research has challenged the notion of free will, providing one pathway for a public shift away from retribution and towards consequentialism. To date, no studies have examined whether educating participants about biopsychosocial effects of trauma that are often outside of conscious awareness may contribute to free will doubt. This study used a 2 (biopsychosocial information, neutral information) × 2 (juvenile offender, adult offender) between subjects design and measured beliefs in free will, judgments of culpability, and justifications for punishment. Results showed a main effect of trauma informed psychoeducation on free will beliefs, such that individuals who watched a trauma video had lower free will beliefs compared to individuals who watched a control video. Direct effects of trauma informed psychoeducation on sentence severity and on justifications for punishment were nonsignificant. However, mediation analyses revealed that free will beliefs had an indirect effect on the relations between trauma informed psychoeducation and perceived culpability and that perceived culpability had an indirect effect on the relations between trauma informed psychoeducation and retribution, consequentialism, and punishment severity.

Abstract
Refugee populations are often characterized by their high exposure to violence, which are tied to various challenges upon resettlement. This systematic review synthesizes the empirical literature related to violence exposure for refugees resettled in high-income countries and the impact of that exposure on mental health symptoms. The authors reviewed quantitative studies published from 2000 to 2018 and found 12 studies met criteria for inclusion. Studies were excluded if the study did not include a measured mental health outcome, if violence exposure was not measured and reported on distinctly from nonviolent exposures, if the sample did not include a refugee population, or if the relationship between violence exposure and mental health of refugees was not empirically examined. Overall, studies found that resettled refugee populations were more likely to have higher rates of violence exposure than comparison groups. This violence exposure was significantly related to higher mental health symptoms, including symptoms of depression, anxiety, and, most commonly reported, posttraumatic stress disorder. However, there is substantial heterogeneity in measurement of violence exposure, particularly in the use of author-created scales. The vast majority of included studies examined only exposure to violence prior to resettlement. The review shows significant evidence for the effect of violence prior to resettlement on mental health after resettlement and reveals a need for improved measurement and definitions of violence exposure at different time points for resettled refugee populations. Assessing current exposure to violence is an important step for effective intervention related to mental health dilemmas for refugee populations.

Abstract
The recent ‘affect revolution’ in strategic decision-making research has placed greater emphasis on the role of stress and emotions in decision-making, with new theorizing to highlight how leader decisions often differ from rational choice expectations. However, while existing theories add to our understanding of the interplay between affect and cognition, they have not yet explained why affect drives decisions in some situations and not others. Undertheorized connections between leaders’ neurobiological windows of tolerance to affect arousal and their self-regulatory capacity—their capacity to regulate stress and emotions so that these phenomena do not drive resulting decisions—may hold the key to explaining this variation in affect’s influence on decision-making. Furthermore, this article considers how leaders’ windows of tolerance have unique ripple effects in their social environments, thereby affecting their groups’ collective window of tolerance. While regulated leaders can convey a calming and creative influence in their organizations that helps the group access strategic decision-making, dysregulated leaders are likely to convey stress and emotion contagion—which may erode the group’s ability to cooperate, adapt, and learn. It illustrates this argument using evidence from the upper echelons of governmental decision-making, comparing New Zealand Prime Minister Jacinda Ardern’s and US President Donald Trump’s responses to the coronavirus pandemic in their respective nations. It concludes by offering hypotheses for testing the argument in future empirical research.

Abstract
Early-life experience influences social and emotional behaviour in adulthood. Affiliative tactile stimuli in early life facilitate the development of social and emotional behaviour, whereas early-life adverse stimuli have been shown to increase the risk of various diseases in later life. On the other hand, oxytocin has been shown to have organizational actions during early-life stages. However, the detailed mechanisms of the effects of early-life experience and oxytocin remain unclear. Here, we review the effects of affiliative tactile stimuli during the neonatal period and neonatal oxytocin treatment on the activity of the oxytocin-oxytocin receptor system and social or emotional behaviour in adulthood. Both affiliative tactile stimuli and early-life adverse stimuli in the neonatal period acutely activate the oxytocin-oxytocin receptor system in the brain but modulate social behaviour and anxiety-related behaviour apparently in an opposite direction in adulthood. Accumulating evidence suggests that affiliative tactile stimuli and exogenous application of oxytocin in early-life stages induce higher activity of the oxytocin-oxytocin receptor system in adulthood, although the effects are dependent on experimental procedures, sex, dosages and brain regions examined. On the other hand, early-life stressful stimuli appear to induce reduced activity of the oxytocin-oxytocin receptor system, possibly leading to adverse actions in adulthood. It is possible that activation of a specific oxytocin system can induce beneficial actions against early-life maltreatments and thus could be used for the treatment of developmental psychiatric disorders.

Abstract
Recent studies suggest that reward anticipation decreases individuals' acute stress responses. However, individuals who have experienced early life stress (ELS) may have a blunted capacity for reward anticipation, which reduces its buffering effect on psychosocial stress responses. To investigate this phenomenon, 66 young adults completed the Trier Social Stress Test following a reward anticipation task, and their ELS levels were measured using the Childhood Trauma Questionnaire (CTQ). Meanwhile, the current study collected biological and psychological measures of stress by analysing cortisol levels, heart rates, heart rate variability (HRV) as well as subjective stress levels, in response to the Trier Social Stress test. Results showed that reward anticipation successfully decreased acute stress responses in general, and it also improved participants' HRV. However, this effect was more evident in individuals with low ELS than those with high ELS. These findings help us deepen understanding of the role of reward anticipation in fostering resilience under stress and the potentially important implications for individuals who have been exposed to ELS are also discussed.

Abstract
BACKGROUND There has been a tremendous increase in the use of smartphones among college students and alongside the benefits there is growing concern over problematic/addictive smartphone use (PSU). Among the most robust predictors of behavioral and substance use disorders are a subset of adverse childhood experiences conceptualized as household dysfunction (HHD). Despite the high prevalence of HHD and risk of PSU among college students, research investigating the link between HHD and PSU among college populations is sparse, especially in the United States. METHODS Students (N = 351) from a diverse, southern California university responded to an online survey. Regression models assessed the association between HHD (e.g., parent alcohol and drug use, mental health, incarceration, suicide, intimate partner violence, separation/divorce, and homelessness; categorized into 0, 1-3, and 4 or more) and PSU using Smartphone Addiction Scale short version (SAS-SV) scale, adjusted for covariates. RESULTS Over 50% of students reported at least one type of household dysfunction and about 25% were at high risk for PSU. Compared to students who report no household stressors, students with 1-3 had twice the odds (AOR: 2.11, 95% CI: 1.13-3.83) and students with 4 or more had four times the odds (AOR: 4.01, 95% CI: 2.35-6.82) of PSU, after adjusting for covariates. There were no sex differences in this association. CONCLUSION Findings suggest that household dysfunction can increase the likelihood of developing behavioral disorders such as PSU. Implications for prevention efforts are discussed.

New insights on nitric oxide: Focus on animal models of schizophrenia. Behav Brain Res 2021; 409:113304.

Abstract
Schizophrenia is a devastating complex disorder characterised by a constellation of behavioral deficits with the underlying mechanisms not fully known. Nitric oxide (NO) has emerged as a key signaling molecule implicated in schizophrenia. Three nitric oxide sinthases (NOS), endothelial, neuronal, and inducible, release NO within the cell. Animal models of schizophrenia are grouped in four groups, neurovedelopmental, glutamatergic, dopaminergic and genetic. In this review, we aim to evaluate changes in NO levels in animal models of schizophrenia and the resulting long-lasting behavioral and neural consequences. In particular, NO levels are substantially modified, region-specific, in various neurodevelopmental models, e.g. bilateral excitotoxic lesion of the ventral hippocampus (nVHL), maternal immune activation and direct NO manipulations early in development, among others. In regards to glutamatergic models of schizophrenia, phencyclidine (PCP) administration increases NO levels in the prefrontal cortex (PFC) and ventral hippocampus. As far as genetic models are concerned, neuronal NOS knock-out mice display schizophrenia-related behaviors. Administration of NO donors can reverse schizophrenia-related behavioral deficits. While most modifications in NO are derived from neuronal NOS, recent evidence indicates that PCP treatment increases NO from the inducible NOS isoform. From a pharmacological perspective, treatment with various antipsychotics including clozapine, haloperidol and risperidone normalize NO levels in the PFC as well as improve behavioral deficits in nVHL rats. NO induced from the neuronal and inducible NOS is relevant to schizophrenia and warrants further research.

Abstract
Children experience trauma and adverse experiences at an alarming rate. The negative impact of traumatic experiences on a child’s developing brain is pervasive, adversely affecting one’s thoughts, feelings, behaviors, physiological reactions, and social relationships. Conversely, the nature, pattern, timing and duration of therapeutic experiences can change the brain in ways that support and cultivate therapeutic growth and healing. The purpose of this paper will be to review and expand on two prominent neurobiological therapeutic frameworks within the field of child trauma therapy: the Neurosequential Model of Therapeutics and Interpersonal Neurobiology. We will discuss the ways in which trauma experiences are organized in the brain and how therapeutic and parenting interventions can address the key areas of the brain that are impacted. Further, this paper will expand on these frameworks to explore how the sacred (within primarily a Judeo-Christian monotheistic religious tradition) can be integrated within the therapeutic process—specifically through the themes of safety, relational connection, and meaning-making.

Abstract
There have been growing concerns about the protracted effects of cannabis use in adolescents on emotion and cognition outcomes, motivated by evidence of growing cannabis use in adolescents, evidence linking cannabis use to various psychiatric disorders, and the increasingly perceived notion that cannabis is harmless. At the same time, studies suggest that cannabinoids may have therapeutic potential against the impacts of stress on the brain and behavior, and that young people sometimes use cannabinoids to alleviate feelings of depression and anxiety (i.e., “self-medication”). Exposure to early adverse life events may predispose individuals to developing psychopathology in adulthood, leading researchers to study the causality between early life factors and cognitive and emotional outcomes in rodent models and to probe the underlying mechanisms. In this review, we aim to better understand the long-term effects of cannabinoids administered in sensitive developmental periods (mainly adolescence) in rodent models of early life stress. We suggest that the effects of cannabinoids on emotional and cognitive function may vary between different sensitive developmental periods. This could potentially affect decisions regarding the use of cannabinoids in clinical settings during the early stages of development and could raise questions regarding educating the public as to potential risks associated with cannabis use.

Abstract
OBJECTIVE To examine levels of plasma osteopontin (OPN), a recently described neuroinflammatory biomarker, in children with abusive head trauma (AHT) compared with children with other types of traumatic brain injury (TBI). STUDY DESIGN The study cohort comprised children aged <4 years diagnosed with TBI and seen in the intensive care unit in a tertiary children's hospital. Patients were classified as having confirmed or suspected AHT or TBI by other mechanisms (eg, motor vehicle accidents), as identified by a Child Protection Team clinician. Serial blood samples were collected at admission and at 24, 48, and 72 hours after admission. Levels of OPN were compared across groups. RESULTS Of 77 patients identified, 24 had confirmed AHT, 12 had suspected AHT, and 41 had TBI. There were no differences in the Glasgow Coma Scale score between the patients with confirmed AHT and those with suspected AHT and those with TBI (median score, 4.5 vs 4 and 7; P = .39). At admission to the emergency department, OPN levels were significantly higher in children with confirmed AHT compared with the other 2 groups (mean confirmed AHT, 471.5 ng/mL; median suspected AHT, 322.3 ng/mL; mean TBI, 278.0 ng/mL; P = .03). Furthermore, the adjusted mean trajectory levels of OPN were significantly higher in the confirmed AHT group compared with the other 2 groups across all subsequent time points (P = <.01). CONCLUSIONS OPN is significantly elevated in children with confirmed AHT compared with those with suspected AHT and those with other types of TBI. OPN expression may help identify children with suspected AHT to aid resource stratification and triage of appropriate interventions for children who are potential victims of abuse.

Abstract
BACKGROUND Emerging adulthood (ages 18-26) is a time of identity exploration, experimentation, focusing on self or others, and instability, themes captured in the Inventory of Dimensions of Emerging Adulthood (IDEA). Preliminary evidence suggests that emerging adults (EAs) with a history of adverse childhood experiences (ACE) score differently on transition dimensions than their peers, however, the role of ACE in the IDEA-substance use relationship is unknown. METHOD Data are from a longitudinal study of acculturation and health among Hispanics in California (N = 1,065). Multivariable regression models assessed the association between IDEA and ACE (no ACE, 1-3 ACE, and ≥ 4 ACE) for substance use behaviors over 2 time points. Interaction terms assessed whether ACE moderated the association between subjective perceptions of IDEA at age 20 and substance use at age 24. RESULTS ACE-exposed EAs scored higher on identity exploration, instability, self-focus, and experimentation dimensions than their peers (ps < .01-.001). Scores on experimentation, identity exploration, and self-focus at age 20 were associated with divergent patterns of substance use across ACE exposure categories. In comparison to other groups, individuals in ≥ 4 ACE group who strongly identified with these transition themes at age 20 had the highest probability of binge drinking, past 30-day alcohol, marijuana, and illicit drug use at age 24 (adjusted odds ratios = 1.09-1.49, confidence interval [1.02-2.58]). CONCLUSION Our findings suggest that ACE can affect subjective perceptions of transition themes and increased risk for substance use over time. Implications for substance use prevention efforts tailored to Hispanic EAs are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Sex differences in the interactive effects of early life stress and the endocannabinoid system. Neurotoxicol Teratol 2020; 80:106893. [PMID: 32437941 DOI: 10.1016/j.ntt.2020.106893] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Revised: 05/06/2020] [Accepted: 05/06/2020] [Indexed: 12/15/2022]
Abstract
Sex differences in both the endocannabinoid system and stress responses have been established for decades. While there is ample evidence that the sexes respond differently to stress and that the endocannabinoid system is involved in this response, what is less clear is whether the endocannabinoid system mediates this response to stress differently in both sexes. Also, do the sexes respond similarly to exogenous cannabinoids (CBs) following stress? Can the administration of exogenous CBs normalize the effects of stress and if so, does this happen similarly in male and female subjects? This review will attempt to delineate the stress induced neurochemical alterations in the endocannabinoid system and the resulting behavioral changes across periods of development: prenatal, early neonatal or adolescent in males and females. Within this frame work, we will then examine the neurochemical and behavioral effects of exogenous CBs and illustrate that the response to CBs is determined by the stress history of the animal. The theoretical framework for this endeavor relates to the established effects of adverse childhood experiences (ACE) in increasing substance abuse, depression and anxiety and the possibility that individuals with high ACE scores may consume cannabinoids to "self-medicate". Overall, we see that while there are instances where exogenous cannabinoids "normalize" the adverse effects produced by early stress, this normalization does not occur in all animal models with any sort of consistency. The most compelling report where CB administration appears to normalize behaviors altered by early stress, shows minimal differences between the sexes (Alteba et al., 2016). This is in stark contrast to the majority of studies on early stress and the endocannabinoid system where both sexes are included and show quite divergent, in fact opposite, effects in males and females. Frequently there is a disconnect between neurochemical changes and behavioral changes and often, exogenous CBs have greater effects in stressed animals compared to non-stressed controls. This report as well as others reviewed here do support the concept that the effects of exogenous CBs are different in individuals experiencing early stress and that these differences are not equal in males and females. However, due to the wide variety of stressors used and the range of ages when the stress is applied, additional careful studies are warranted to fully understand the interactive effects of stress and the endocannabinoid system in males and females. In general, the findings do not support the statement that CB self-administration is an effective treatment for the adverse behavioral effects of early maltreatment in either males or females. Certainly this review should draw the attention of clinicians working with children, adolescents and adults exposed to early trauma and provide some perspective on the dysregulation of the endocannabinoid system in the response to trauma, the complex actions of exogenous CBs based on stress history and the unique effects of these factors in men and women.

Abstract
Substantial evidence from various studies suggests a preeminent role for early adverse experiences in the development of psychopathology. The most recent studies reviewed here suggest that early life stressors are associated with an increased risk for anxiety disorders in adulthood. Early life stress predisposes individuals to develop a number of psychiatric syndromes, particularly affective disorders, including anxiety disorders, and is therefore a significant health problem.This review examines the emerging literature on the relationship between stress, hypothalamic-pituitary-adrenal (HPA) axis function, and generalized anxiety disorder (GAD), panic disorder, and phobias and the role of early life stress as an important risk factor for HPA axis dysfunction.The most consistent findings in the literature show increased activity of the HPA axis in depression associated with hypercortisolemia and reduced inhibitory feedback. In addition to melancholic depression, a spectrum of other conditions may be associated with increased and prolonged activation of the HPA axis, including panic, GAD, phobias and anxiety. Moreover, HPA axis changes appear to be state-dependent, tending to improve upon resolution of the anxiety syndrome. Interestingly, persistent HPA hyperactivity has been associated with higher rates of relapse. These studies suggest that an evaluation of the HPA axis during treatment may help identify patients who are at a higher risk for relapse. These findings suggest that this dysfunction of the HPA axis is partially attributable to an imbalance between glucocorticoid and mineralocorticoid receptors. Evidence has consistently demonstrated that glucocorticoid receptor function is impaired in anxiety disorders. Moreover, normal basal cortisol levels and hyper-responsiveness of the adrenal cortex during a psychosocial stressor are observed in social phobics. Finally, abnormal HPA axis activity has also been observed in generalized anxiety disordered patients. Early stressful life events may provoke alterations of the stress response and thus of the HPA axis that can endure during adulthood, predisposing individuals to develop psychopathology.

Abstract
The goal of the study was to describe the nature of adverse childhood experiences (ACEs) reported by undergraduates and to examine the effect of ACEs, perceived stress, and perceived social support on their health. Although respondents (N = 321) had parents with relatively high levels of education and indicated generally high levels of social support, results nevertheless showed a relatively high level of mental health problems and rates of ACEs that were similar to those in the general population in the state. Those with higher levels of ACEs had greater levels of stress and lower levels of social support. ACEs, social support, and stress explained more than half the variance in mental health scores, with stress making the greatest contribution. Despite the fact that we used different measures and an independent sample, findings generally replicated a previous study. Results point to a need to increase awareness of the association between ACEs and health on college campuses, to examine the effects of ACEs in more detail, and to design ACE-informed programs for this population.

Abstract
BACKGROUND Posttraumatic stress symptoms are common after discharge from military service in male and female Post-9/11 veterans, many of whom experienced combat. OBJECTIVE This is a study of the impacts of childhood and adult assaults are studied both separately and together on the level of posttraumatic stress symptoms in male and female Post-9/11 veterans (N = 850) after discharge from military service. PARTICIPANTS AND SETTING This cross-sectional secondary analysis uses data from the baseline interviews of the Survey of Experiences of Returning Veterans (SERV) cohort study. METHODS Childhood sexual and physical abuse, adult sexual and physical assault, and combat exposure were the main exposures of interest and the primary outcome measurement was the Posttraumatic Symptom Checklist-Civilian, assessing symptom severity post discharge from military service. RESULTS Our sample reported high rates of childhood abuse, adult victimization, combat exposure, and posttraumatic stress symptoms. Tested separately, models including different types of victimization had both unique (f2 = 0.30) and cumulative (f2 = 0.32) effects on severity of posttraumatic stress symptoms in male and female veterans. CONCLUSIONS Our results underscore the importance of assessing childhood and adult trauma history in returning veterans in addition to traumas they experienced during their service. These findings highlight the importance of focusing on building resilience in our military servicemembers.

Abstract
The manifestation of risk versus resilience has been considered from varying perspectives including genetics, epigenetics, early life experiences, and type and intensity of the challenge with which the organism is faced. Although all of these factors are central to determining risk and resilience, the current review focuses on what may be a final common pathway: metabolism. When an organism is faced with a perturbation to the environment, whether internal or external, appropriate energy allocation is essential to resolving the divergence from equilibrium. This review examines the potential role of metabolism in the manifestation of stress-induced neural compromise. In addition, this review details the current state of knowledge on neuroendocrine factors which are poised to set the tone of the metabolic response to a systemic challenge. The goal is to provide an essential framework for understanding stress in a metabolic context and appreciation for key neuroendocrine signals.

Abstract
Emotional distress during pregnancy is likely influenced by both maternal history of adversity and concurrent prenatal stressors, but prospective longitudinal studies are lacking. Guided by a life span model of pregnancy health and stress sensitization theories, this study investigated the influence of intimate partner violence (IPV) during pregnancy on the association between childhood adversity and prenatal emotional distress. Participants included an urban, community-based sample of 200 pregnant women (aged 18-24) assessed annually from ages 8 to 17 for a range of adversity domains, including traumatic violence, harsh parenting, caregiver loss, and compromised parenting. Models tested both linear and nonlinear effects of adversity as well as their interactions with IPV on prenatal anxiety and depression symptoms, controlling for potential confounds such as poverty and childhood anxiety and depression. Results showed that the associations between childhood adversity and pregnancy emotional distress were moderated by prenatal IPV, supporting a life span conceptualization of pregnancy health. Patterns of interactions were nonlinear, consistent with theories conceptualizing stress sensitization through an "adaptive calibration" lens. Furthermore, results diverged based on adversity subdomain and type of prenatal IPV (physical vs. emotional abuse). Findings are discussed in the context of existing stress sensitization theories and highlight important avenues for future research and practice.

Abstract
Although the neonatal and infancy period is short, it is well documented that the early neonatal environment is critical for appropriate physical, behavioral, and cognitive development that lasts into adulthood. Dairy calves are commonly removed from the dam shortly after birth and raised in individual housing and fed limited milk allowances (4 to 6 L/d) in commercial farms around the world (conventional raising). Individual housing was developed to promote health status and facilitate individual animal monitoring. However, it is associated with high labor demand, and early life social isolation is associated with cognitive and behavioral abnormalities. Recently, group housing and enhanced milk-feeding programs are being increasingly adopted by farms; these practices more closely resemble the social and nutritional environments in natural or seminatural environments when the calf is raised with the dam. Conventional raising may lead to short- and long-term effects when compared to calves raised with the dam or peers. Short-term effects of conventional raising include impaired social skills when introduced to novel peers, reduced consumption of novel feeds, increased activity in a novel environment, and signs of hunger associated with limited milk intake and poor growth during the preweaning period. Evidence also suggests that the long-term effects of conventional artificial raising systems include behavioral differences, such as lower social submissiveness, increased heart rate and cortisol when presented with a novel environment, and production differences such as milk yield and reproductive performance. However, research on the long-term effects of maternal, social, physical, and nutritional restrictions in early life is still limited and should be encouraged. More research is needed to determine the long-term effects of artificial raising systems (individual, group housing, dam-raised) on future behavior, cognition, performance, and health parameters in dairy calves.

Abstract
INTRODUCTION Borderline Personality Disorder (BPD) and Bipolar Affective Disorder (BD) have clinical characteristics in common which often make their differential diagnosis difficult. The history of early life stress (ELS) may be a differentiating factor between BPD and BD, as well as its association with clinical manifestations and specific neuroendocrine responses in each of these diagnoses. OBJECTIVE Assessing and comparing patients with BD and BPD for factors related to symptomatology, etiopathogenesis and neuroendocrine markers. METHODOLOGY The study sample consisted of 51 women, divided into 3 groups: patients with a clinical diagnosis of BPD (n = 20) and BD (n = 16) and healthy controls (HC, n = 15). Standardized instruments were used for the clinical evaluation, while the history of ELS was quantified with the Childhood Trauma Questionnaire (CTQ), and classified according to the subtypes: emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect. The functioning of the hypothalamic-pituitary-adrenal (HPA) axis was evaluated by measuring a single plasma cortisol sample. RESULTS Patients with BPD presented with more severe psychiatric symptoms of: anxiety, impulsivity, depression, hopelessness and suicidal ideation than those with BD. The history of ELS was identified as significantly more prevalent and more severe in patients (BPD and BP) than in HC. Emotional abuse, emotional neglect and physical neglect also showed differences and were higher in BPD than BD patients. BPD patients had greater severity of ELS overall and in the subtypes of emotional abuse, emotional neglect and physical neglect than BD patients. The presence of ELS in patients with BPD and BP showed significant difference with lower cortisol levels when compared to HC. The endocrine evaluation showed no significant differences between the diagnoses of BPD and BD. Cortisol measured in patients with BPD was significantly lower compared to HC in the presence of emotional neglect and physical neglect. A significant negative correlation between the severity of hopelessness vs cortisol; and physical neglect vs cortisol were found in BPD with ELS. The single cortisol sample showed a significant and opposite correlations in the sexual abuse diagnosis-related groups, being a negative correlation in BD and positive in BPD. DISCUSSION Considering the need for a multi-factorial analysis, the differential diagnosis between BPD and BD can be facilitated by the study of psychiatric symptoms, which are more severe in the BPD patients with a history of early life stress. The function of the HPA axis assessed by this cortisol measure suggests differences between BPD and BP with ELS history. CONCLUSION The integrated analysis of psychopathology, ELS and neuroendocrine function may provide useful indicators to differentiate BPD and BD diagnoses. These preliminary data need to be replicated in a more significant sample with improved and multiple assessments of HPA axis activity.

Abstract
Since the pioneering finding of Caspi and co-workers in 2002 that exposure to childhood maltreatment predicted later antisocial behaviour (ASB) in male carriers of the low-activity MAOA-uVNTR allele, frequent replication studies have been published. Two meta-analyses, one in 2006 and the other in 2014, confirmed the original findings by Caspi and co-workers. In the present paper, we review the literature, note some methodological aspects of candidate gene–environment interaction (cG×E) studies and suggest some future directions. Our conclusions are as follows. (1) The direction of the effect in a cG×E model may differ according to the positive and negative environmental background of the population. (2) There is a predictor-intersection problem such that when measuring one type of maltreatment in a person, other kinds of maltreatment often co-occur. Other forms of abuse are implicitly considered in statistical models; therefore, it is difficult to draw conclusions about the effects of timing and the severity of different forms of stressful life events in relation to ASB. (3) There is also an outcome-intersection problem because of the major intersection of ASB and other forms of mental health problems. It is likely that the G×E with MAOA is related to a common unmeasured factor. (4) For the G×E model, in which the effect of the gene on the outcome variable is dependent on other predictor variables, theoretically, hypothesis-driven statistical modelling is needed.

Abstract
For the last five decades, science has managed to delineate the mechanisms by which stress hormones can impact on the human brain. Receptors for glucocorticoids are found in the hippocampus, amygdala and frontal cortex, three brain regions involved in memory processing and emotional regulation. Studies have shown that chronic exposure to stress is associated with reduced volume of the hippocampus and that chronic stress can modulate volumes of both the amygdala and frontal cortex, suggesting neurotoxic effects of stress hormones on the brain. Yet, other studies report that exposure to early adversity and/or familial/social stressors can increase vulnerability to stress in adulthood. Models have been recently developed to describe the roles that neurotoxic and vulnerability effects can have on the developing brain. These models suggest that developing early stress interventions could potentially counteract the effects of chronic stress on the brain and results going along with this hypothesis are summarized.

Abstract
AbstractExposure to childhood adversity has been linked to accelerated telomere shortening, a marker of cellular aging and an indicator of physical health risk. In the current study, we examined whether adult attachment representation moderated the association between childhood adversity and telomere length. Participants included 78 young adults (M age = 20.46, SD = 1.57), who reported on their exposure to adverse childhood experiences (ACE) and were administered the Adult Attachment Interview, which was coded for attachment state of mind. Relative telomere length was assayed from buccal cells. Multiple regression analyses revealed a significant interaction between attachment state of mind and ACE in predicting telomere length. Whereas the association between number of ACE and telomere length was nonsignificant for secure–autonomous, r (50) = –.15, p = .31, and insecure–preoccupied young adults, r (9) = –.15, p = .71, there was a strong negative association between number of ACE and telomere length for insecure–dismissing young adults, r (19) = –.59, p = .007. This study is novel in demonstrating that attachment may affect biological resilience following childhood adversity, contributing to the growing literature about the role of the quality of early caregiving experiences and their representations in shaping biological processes and physical health.

Abstract
OBJECTIVE Psychological risk factors (PRFs) are associated with impaired learning and memory in HIV-infected (HIV+) women. We determined the dynamic nature of the effects of PRFs and HIV serostatus on learning and memory over time. DESIGN Multi-center, prospective cohort study METHODS:: Every two years between 2009 and 2013 (3 times), 646 HIV+ and 300 demographically-similar HIV-uninfected (HIV-) women from the Women's Interagency HIV Study completed neuropsychological (NP) testing and questionnaires measuring PRFs (perceived stress, post-traumatic stress disorder (PTSD) symptoms, depressive symptoms). Using mixed-effects regressions, we examined separate and interactive associations between HIV-serostatus and PRFs on performance over time. RESULTS HIV+ and HIV- women had similar rates of PRFs. Fluency was the only domain where performance over time depended on the combined influence of HIV-serostatus and stress or PTSD (p's < 0.05); not depression. In HIV, higher stress and PTSD were associated with a greater cognitive decline in performance (p's < 0.05) versus lower stress and PTSD. Irrespective of time, performance on learning and memory depended on the combined influence of HIV-serostatus and stress or PTSD (p's ≤ 0.05). In the context of HIV, stress and PTSD were negatively associated with performance. Effects were pronounced on learning among HIV+ women without effective treatment or viral suppression. Regardless of time or HIV-serostatus, all PRFs were associated with lower speed, global NP, and executive function. CONCLUSIONS More than depression, perceived stress and PTSD symptoms are treatment targets to potentially improve fluency, learning, and memory in women living with HIV particularly when HIV treatment is not optimal.

Abstract
Epigenetically programmed stress adaptation may be a conduit for informing offspring of environmental challenge. We employed ChIP-sequencing to examine effects of early environment on epigenetic regulation using hippocampal samples from macaques exposed to disruption in maternal care. We found decreased H3K4me3 binding at genes critical to behavioral stress response, the most robust being the oxytocin receptor gene (OXTR), for which we observed a corresponding decrease in RNA expression. Post hoc analysis showed that a gain-of-function OXTR SNP rescued behavioral differences in early stress-exposed subjects. Our data suggest that epigenetic down-modulation of OXTR in brain could contribute to behavioral differences observed in early stress-exposed subjects and that functional genetic variation plays a role. These could have translational implications for human psychiatric disease and personality disorders. Adaptations to stress can occur through epigenetic processes and may be a conduit for informing offspring of environmental challenge. We employed ChIP-sequencing for H3K4me3 to examine effects of early maternal deprivation (peer-rearing, PR) in archived rhesus macaque hippocampal samples (male, n = 13). Focusing on genes with roles in stress response and behavior, we assessed the effects of rearing on H3K4me3 binding by ANOVA. We found decreased H3K4me3 binding at genes critical to behavioral stress response, the most robust being the oxytocin receptor gene OXTR, for which we observed a corresponding decrease in RNA expression. Based on this finding, we performed behavioral analyses to determine whether a gain-of-function nonsynonymous OXTR SNP interacted with early stress to influence relevant behavioral stress reactivity phenotypes (n = 194), revealing that this SNP partially rescued the PR phenotype. PR infants exhibited higher levels of separation anxiety and arousal in response to social separation, but infants carrying the alternative OXTR allele did not exhibit as great a separation response. These data indicate that the oxytocin system is involved in social-separation response and suggest that epigenetic down-modulation of OXTR could contribute to behavioral differences observed in PR animals. Epigenetic changes at OXTR may represent predictive adaptive responses that could impart readiness to respond to environmental challenge or maintain proximity to a caregiver but also contribute to behavioral pathology. Our data also demonstrate that OXTR polymorphism can permit animals to partially overcome the detrimental effects of early maternal deprivation, which could have translational implications for human psychiatric disorders.

Abstract
HIV-associated neurocognitive disorders (HAND) are increasingly prevalent despite the use of antiretroviral therapies. Previous research suggests that individual host factors play an important role in determining susceptibility to HAND. In this review, we propose that childhood trauma (CT) and HAND share several common aetiological mechanisms, namely hypothalamic-pituitary-adrenal axis dysregulation, neuroinflammation and oxidative stress. These convergent and consequent mechanisms may translate into an increased risk of developing HAND in individuals who have experienced early life stress. We provide an overview of basic and clinical research relating to these pathophysiological mechanisms and suggest that further research examine brain-derived neurotrophic factor and telomere length as common mediating factors and potential therapeutic targets for HAND and CT. Graphical abstract Both childhood trauma and HIV-associated neurocognitive disorders are associated with HPA axis dysregulation, inflammation and oxidative stress.

Abstract
PURPOSE OF REVIEW Since 1980, posttraumatic stress (PTS) disorder has been controversial because of its origin as a social construct, its discriminating trauma definition, and the Procrustean array of symptoms/clusters chosen for inclusion/exclusion. This review summarizes the history of trauma-related nosology and proposed changes, within current categorical models (trauma definitions, symptoms/clusters, subtypes/specifiers, disorders) and new models. RECENT FINDINGS Considering that trauma is a risk factor for virtually all mental disorders (particularly depressive, anxiety, dissociative, personality), the multi-finality of trauma (some survivors are resilient, and some develop PTS and/or non-PTS symptoms), and the various symptoms that trauma survivors express (mood, cognitive, perceptual, somatic), it is difficult to classify PTS. Because the human mind best comprehends categories, reliable classification generally necessitates using a categorical nosology but PTS defies categories (internalizing and/or externalizing, fear-based and/or numbing symptoms), the authors conclude that PTS-like DSM-5's panic attacks specifier-is currently best conceptualized as a specifier for other mental disorders.

Abstract
PURPOSE OF REVIEW Still obscure mechanisms of intergenerational child maltreatment (ITCM) have been investigated partially, from various psychological and biological perspectives and from various time perspectives. This review is aimed at integrating the findings on different temporal ITCM pathways, emphasizing the mind-brain-body interplay. RECENT FINDINGS Psychological mediators of ITCM involve attachment, mentalization, dissociation, social information processing, personality traits, and psychiatric disorders. Neurobiological findings mostly refer to the neural correlates of caregiving and attachment behaviors, affected by several physiological systems (stress-response, immune, oxytocin), which also affect physical health. The latest research clusters around the epigenetic pathways of ITCM, suggesting the additional, prenatal, and preconception forms of transmission. Data suggest that ITCM needs to be conceptualized as a longitudinal process, with various interrelated psychological, neurodevelopmental, and somatic paths. Future research and prevention should take into account both, each path and each phase of ITCM, in an integrative way.

Abstract
Adolescence is a time period in development when the brain undergoes substantial remodeling in response to the environment. To determine whether a stressful experience during adolescence affects adult behavior, we exposed adolescent male and female C57BL/6J mice to chronic unpredictable stress (CUS) for 12 days starting at postnatal day 28 (PND28). We also exposed adult male and female mice to CUS for 12 days beginning at PND70 to determine whether adolescence is a sensitive time period when stress can have long-lasting effects on behavior. Regardless of when mice were exposed to stress, they were all tested exactly 30 days later in the marble burying task, elevated zero maze, acoustic startle response, and forced swim test. Adolescent stress exposure increased anxiety-like behaviors in adult male and female mice and decreased acoustic startle response in a sex-dependent manner. However, adult stress exposure did not change anxiety or response to an acoustic tone in adult male or female mice as compared with nonstressed animals. Of interest, increased depression-like behavior in the forced swim test was observed in all mice, regardless of when the stress occurred. Gene expression analysis showed significant upregulation of corticotropin releasing factor receptor 2 (CrfR2) in the amygdala of males subjected to CUS during adolescence, but not in males that experienced CUS during adulthood. In contrast, females, regardless of when they were exposed to CUS, were not affected. These data support clinical evidence suggesting that early-life stress may predispose individuals to increased anxiety and depression later in life.

Exposure to chronic early-life stress lastingly alters the adipose tissue, the leptin system and changes the vulnerability to western-style diet later in life in mice. Psychoneuroendocrinology 2017; 77:186-195.

Abstract
Early-life stress (ES) increases the vulnerability to develop psychopathologies and cognitive decline in adulthood. Interestingly, this is often comorbid with metabolic disorders, such as obesity. However, it is unclear whether ES leads to lasting metabolic changes and to what extent this is associated with the ES-induced cognitive impairments. Here, we used an established chronic ES mouse model (from postnatal day (P) 2 to P9) to investigate the short- and long-term effects of ES exposure on parameters of the adipose tissue and the leptin system (i.e. circulating levels and gene expression of leptin and its receptor) in both sexes. Immediately following ES, the offspring exhibited reductions in white adipose tissue (WAT) mass, plasma leptin levels and in leptin mRNA expression in WAT. Furthermore, ES exposure led to increased brown adipose tissue and browning of WAT, which was evident by a drastic increase in uncoupling protein 1 mRNA expression in the inguinal WAT at P9. Notably, the ES-induced reductions in WAT mass, plasma leptin and leptin expression in WAT were sustained into adulthood and were accompanied by changes in body fat distribution, such as a higher ratio between mesenteric WAT and other WATs. Interestingly, while ES exposure increased leptin receptor mRNA expression in the choroid plexus, it was unaltered in the hippocampus. This suggests an adaptation to maintain central leptin homeostasis following ES exposure. In addition, chronic ES exposure resulted in the well-established cognitive impairment in object recognition performance during adulthood, which correlated positively with reductions in WAT mass observed in male, but not in female mice. Finally, to assess if ES leads to a different metabolic phenotype in a moderate obesogenic environment, we measured body fat accumulation of control and ES-exposed mice in response to a moderate western-style diet (WSD) that was provided during adulthood. ES-exposed mice subjected to WSD exhibit a higher increase in adiposity when compared to controls, suggesting that ES exposure might result in a higher vulnerability to develop obesity in a moderate obesogenic environment. To conclude, chronic ES exposure alters parameters of the adipose tissue, leads to central adaptations in leptin regulation and results in higher fat accumulations when exposed to a WSD challenge later in life. A better understanding of these metabolic effects induced by ES might open up new avenues for therapeutic (e.g. nutritional) interventions.

Abstract
Animals, including humans, require a highly coordinated and flexible system of social behavior and threat evaluation. However, trauma can disrupt this system, with the amygdala implicated as a mediator of these impairments in behavior. Recent evidence has further highlighted the context of infant trauma as a critical variable in determining its immediate and enduring consequences, with trauma experienced from an attachment figure, such as occurs in cases of caregiver-child maltreatment, as particularly detrimental. This review focuses on the unique role of caregiver presence during early-life trauma in programming deficits in social behavior and threat processing. Using data primarily from rodent models, we describe the interaction between trauma and attachment during a sensitive period in early life, which highlights the role of the caregiver's presence in engagement of attachment brain circuitry and suppressing threat processing by the amygdala. These data suggest that trauma experienced directly from an abusive caregiver and trauma experienced in the presence of caregiver cues produce similar neurobehavioral deficits, which are unique from those resulting from trauma alone. We go on to integrate this information into social experience throughout the lifespan, including consequences for complex scenarios, such as dominance hierarchy formation and maintenance.

Abstract
Environmental enrichment is a widespread neuroprotective strategy during development and also in the mature nervous system. Several research groups have described that enriched environment in adult rats has an impact on the progression of Parkinson's disease (PD). The aim of our present study was to examine the effects of early, postnatal environmental enrichment after 6-hydroxydopamine-induced (6-OHDA) lesion of the substantia nigra in adulthood. Newborn Wistar rats were divided into control and enriched groups according to their environmental conditions. For environmental enrichment, during the first five postnatal weeks animals were placed in larger cages and exposed to intensive complex stimuli. Dopaminergic cell loss, and hypokinetic and asymmetrical signs were evaluated after inducing PD with unilateral injections of 6-OHDA in three-month-old animals. Treatment with 6-OHDA led to a significant cell loss in the substantia nigra of control animals, however, postnatal enriched circumstances could rescue the dopaminergic cells. Although there was no significant difference in the percentage of surviving cells between 6-OHDA-treated control and enriched groups, the slightly less dopaminergic cell loss in the enriched group compared to control animals resulted in less severe hypokinesia. Our investigation is the first to provide evidence for the neuroprotective effect of postnatal enriched environment in PD later in life.

Abstract
Caregiver maltreatment induces vulnerability to later-life psychopathology. Clinical and preclinical evidence suggest changes in prefrontal and limbic circuitry underlie this susceptibility. We examined this question using a rat model of maternal maltreatment and methods translated from humans, resting-state functional magnetic resonance imaging (R-fMRI). Rat pups were reared by mothers provided with insufficient or abundant bedding for nest building from postnatal (PN) days 8 to 12 and underwent behavioral assessments of affect-related behaviors (forced swim, sucrose preference and social interaction) in adolescence (PN45) and early adulthood (PN60). R-fMRI sessions were conducted under light anesthesia at both ages. Offspring reared with insufficient bedding (that is, maltreated) displayed enduring negative affective behaviors. Amygdala-prefrontal cortex (PFC) functional connectivity increased significantly from adolescence to adulthood in controls, but not in maltreated animals. We computed the fractional amplitude of low-frequency fluctuations (fALFF), an index of intrinsic brain activity, and found that fALFF in medial prefrontal cortex and anterior cingulate cortex (MPFC/ACC) increased significantly with age in controls but remained unchanged in maltreated animals during adolescence and adulthood. We used a seed-based analysis to explore changes in functional connectivity between this region and the whole brain. Compared with controls, maltreated animals demonstrated reduced functional connectivity between MPFC/ACC and left caudate/putamen across both ages. Functional connectivity between MPFC/ACC and right caudate/putamen showed a group by age interaction: decreased in controls but increased in maltreated animals. These data suggest that maltreatment induces vulnerability to psychopathology and is associated with differential developmental trajectories of prefrontal and subcortical circuits underlying affect regulation.
