Willford JA, Kaufman JM. Through a teratological lens: A narrative review of exposure to stress and drugs of abuse during pregnancy on neurodevelopment. Neurotoxicol Teratol 2024; 105:107384. [PMID: 39187031 DOI: 10.1016/j.ntt.2024.107384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 08/20/2024] [Accepted: 08/21/2024] [Indexed: 08/28/2024]
Abstract
Teratological research shows that both prenatal stress and prenatal substance exposure have a significant impact on neurodevelopmental outcomes in children. Using human research, the purpose of this narrative review is to explore the degree to which these exposures may represent complex prenatal and postnatal risks for the development of cognition and behavior in children. An understanding of the HPA axis and its function during pregnancy as well as the types and operationalization of prenatal stress provide a context for understanding the direct and indirect mechanisms by which prenatal stress affects brain and behavior development. In turn, prenatal substance exposure studies are evaluated for their importance in understanding variables that indicate a potential interaction with prenatal stress including reactivity to novelty, arousal, and stress reactivity during early childhood. The similarities and differences between prenatal stress exposure and prenatal substance exposure on neurodevelopmental outcomes including arousal and emotion regulation, cognition, behavior, stress reactivity, and risk for psychopathology are summarized. Further considerations for teratological studies of prenatal stress and/or substance exposure include identifying and addressing methodological challenges, embracing the complexity of pre-and postnatal environments in the research, and the importance of incorporating parenting and resilience into future studies.

Altered circadian expression of clock genes and clock-regulatory epigenetic modifiers in saliva of children with fetal alcohol spectrum disorders. Sci Rep 2024; 14:19886. [PMID: 39191924 DOI: 10.1038/s41598-024-71023-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Accepted: 08/23/2024] [Indexed: 08/29/2024] Open
Abstract
Prenatal alcohol-exposed (AE) infants and children often demonstrate disrupted sleep patterns, including more frequent awakenings, reduced total sleep time, and more night-to-night sleep variability. Despite the strong connection between sleep patterns and circadian rhythmicity, relatively little is known about circadian rhythm disruptions in individuals with AE. Recently, several reports demonstrated that evaluating the expression patterns of human clock genes in biological fluids could reveal an individual's circadian phenotype. Human saliva offers an emerging and easily available physiological sample that can be collected non-invasively for core-clock gene transcript analyses. We compared the expression patterns of core-clock genes and their regulatory genes in salivary samples of children aged 6-10 years-old with and without AE during the light cycle between ZT0-ZT11. We isolated the RNA from the samples and measured the expression patterns of core clock genes and clock regulating genes using the human specific primers with quantitative real-time PCR. Analysis of core clock genes expression levels in saliva samples from AE children indicates significantly altered levels in expression of core-clock BMAL1, CLOCK, PER1-3 and CRY1,2, as compared to those in age-matched control children. We did not find any sex difference in levels of clock genes in AE and control groups. Cosinor analysis was used to evaluate the rhythmic pattern of these clock genes, which identified circadian patterns in the levels of core clock genes in the control group but absent in the AE group. The gene expression profile of a salivary circadian biomarker ARRB1 was rhythmic in saliva of control children but was arhythmic in AE children. Altered expression patterns were also observed in clock regulatory genes: NPAS2, NFL3, NR1D1, DEC1, DEC2, and DBP, as well as chromatin modifiers: MLL1, P300, SIRT1, EZH2, HDAC3, and ZR1D1, known to maintain rhythmic expression of core-clock genes. Overall, these findings provide the first evidence that AE disturbs the circadian patten expression of core clock genes and clock-regulatory chromatin modifiers in saliva.

Abstract
Though considerable work supports the Dimensional Model of Adversity and Psychopathology, prior research has not tested whether the dimensions-threat (e.g., abuse) and deprivation (e.g., neglect)-are uniquely related to salivary trait indicators of hypothalamic pituitary adrenal (HPA) axis activity. We examined the unique and interactive effects of threat and deprivation on latent trait cortisol (LTC)-and whether these effects were modified by co-occurring adversities. Emerging adults (n = 90; Mage = 19.36 years; 99.88% cisgender women) provided salivary cortisol samples four times a day (waking, 30 min and 45 min postwaking, bedtime) over three 3-day measurement waves over 13 weeks. Contextual life stress interviews assessed early adversity. Though the effects varied according to the conceptualization of early adversity, overall, threat-but not deprivation, nor other co-occurring adversities-was uniquely associated with the across-wave LTC. Specifically, the incidence and frequency of threat were each negatively related to the across-wave LTC. Threat severity was also associated with the across-wave LTC, but only among those with no deprivation. Finally, the effects of threat were modified by other co-occurring adversities. Findings suggest that threat has unique implications for individual differences in HPA axis activity among emerging adults, and that co-occurring adversities modify such effects.

Abstract
Prenatal alcohol exposure is the leading nongenetic cause of human intellectual impairment. The long-term impacts of prenatal alcohol exposure on health and well-being are diverse, including neuropathology leading to behavioral, cognitive, and emotional impairments. Additionally negative effects also occur on the physiological level, such as the endocrine, cardiovascular, and immune systems. Among these diverse impacts is sleep disruption. In this review, we describe how prenatal alcohol exposure affects sleep, and potential mechanisms of those effects. Furthermore, we outline the evidence that sleep disruption across the lifespan may be a mediator of some cognitive and behavioral impacts of developmental alcohol exposure, and thus may represent a promising target for treatment.

Abstract
BACKGROUND Exposure to socioeconomic adversity is hypothesized to impact hypothalamic-pituitary-adrenal (HPA) axis activity and cortisol secretion, but existing evidence is inconsistent. Yet, few studies have investigated this association using a developmental approach that considers potential protective contextual factors. This study examined the role of stability and changes in family socioeconomic status (SES) in the prediction of multiple cortisol indicators and tested whether social support moderated these associations. METHODS Participants were part of a population-based sample of twin pairs recruited at birth. Family SES was assessed in early childhood (ages 0-5) and mid-adolescence (age 14). Social support was assessed at ages 14 and 19. Diurnal cortisol (n = 569) was measured at age 14 at awakening, 30 min later, in the afternoon and evening over four non-consecutive days. Hair cortisol concentration (HCC, n = 704) was measured at age 19. All data were collected before the pandemic and multilevel regression models were conducted to account for the nested data structure. RESULTS Youth exposed to lower family SES levels in childhood and mid-adolescence had a flatter diurnal slope and higher HCC compared with those who experienced upward socioeconomic mobility in mid-adolescence. Contrastingly, mid-adolescence SES showed no association with the diurnal slope or HCC for youth from higher-SES households in early childhood. Moreover, youth raised in higher-SES families in early childhood had a higher CAR in mid-adolescence if they reported greater social support in mid-adolescence. Social support also moderated the SES-cortisol association in mid-adolescence, with higher-SES youth showing higher awakening cortisol secretion when reporting more social support. CONCLUSIONS Our findings support the hypothesis that early socioeconomic adversity sensitizes HPA axis activity to later socioeconomic disadvantage, which may bear consequences for socioemotional and behavioral functioning.

Abstract
We undertook a scoping review to identify the factors outside of current fetal alcohol spectrum disorder (FASD) diagnostic criteria to be considered as part of a holistic assessment process. This included physical, social, cultural, mental health and wellbeing factors to inform targeted recommendations and supports to improve outcomes for individuals with FASD. Evidence from this review will be used to inform the revision of the Australian Guide to the Diagnosis of FASD. Six electronic databases were searched. Studies were eligible if they included factors outside of the diagnostic criteria that cover dysmorphology, growth restriction, neurodevelopmental impairments. Data charting and content analysis were performed to synthesize the results. One hundred twenty-one studies were included that spanned 12 key areas These included physical health, sleep, adverse postnatal experiences, substance use/other risk-taking behaviors, contact with the criminal justice system, mental health, First Nations cultural considerations, transition to adult roles, involvement with the out-of-home care system, feeding and eating, strengths/interests/external resources and incontinence. Areas to be considered as part of a holistic assessment and diagnostic process spanned individual, family, and system level factors. Results provide guidance for clinicians on the wide range of factors that could influence long-term health, development, and wellbeing for individuals with prenatal alcohol exposure and FASD. In practice, this guidance can be used to inform an individualized assessment process to facilitate tailored recommendations and supports to best meet the complex needs of individuals living with FASD and their families.

Abstract
Mental and psychological disorders are serious health problems worldwide. Anxiety among high school students can affect school performance, relationships, and family life. OBJECTIVE Our aim is to understand the anxiety levels and associated factors among high school students and compare the results of psychological tests measuring anxiety with the cortisol levels obtained from biological sampling. METHOD In our longitudinal follow-up study, we involved 125 individuals in May 2019. Validated measurement tools were used during questionnaire data collection, including the State-Trait Anxiety Inventory, Clear Communication Scale, Multiple Social Perceived Support Scale, and related HBSC questions. As objective data, we collected hair samples for cortisol level measurement. RESULTS At the end of the school year, the anxiety levels measured by psychological tests were significantly higher (p = 0.001) compared to the anxiety levels at the beginning of the next school year. Anxiety levels were higher among girls and were influenced by the type of school and parental expectations. Both state anxiety and trait anxiety showed a strong correlation with psychosomatic symptoms (p < 0.001) and anxiety arising from school expectations (p < 0.05). The changes in cortisol levels did not follow the changes in psychological tests. Cortisol level increased (p = 0.01) in the second sample.

Abstract
BACKGROUND Parental support of child play varies based on child needs; however, how parental play level differs from child play level remains an understudied area of research, especially in relation to specific developmental disabilities. AIMS To preliminarily explore differences in child and parent play levels in age- and IQ-matched children with fetal alcohol spectrum disorders (FASD) and autism spectrum disorder (ASD). METHODS and Procedures: Parent-child dyads were recorded during free-play sessions. Parent/child play levels were coded for highest level achieved during each minute of play. Mean play level and dPlay (difference in parent versus child play level) were calculated across play sessions for each dyad. OUTCOMES AND RESULTS On average, parents of children with FASD demonstrated higher levels of play than other parents. Children with FASD demonstrated higher levels of play than their own parents. In contrast, the play level of parents of children with ASD did not differ from their child's. There were no between-group differences in dPlay. CONCLUSIONS AND IMPLICATIONS This preliminary exploratory study suggests that parents of children with developmental disabilities may differentially 'match' their child's play level. Further research on developmental play levels during parent-child play is warranted.

Abstract
While converging evidence suggests that both environmental and genetic factors underlie variations in diurnal cortisol, the extent to which these sources of influence vary according to socioeconomic status (SES) has seldom been investigated, particularly in adolescence. To investigate whether a distinct genetic and environmental contribution to youth's diurnal cortisol secretion emerges according to family SES and whether the timing of these experiences matters. Participants were 592 twin pairs, who mostly came from middle-income and intact families and for whom SES was measured in childhood and adolescence. Diurnal cortisol was assessed at age 14 at awakening, 30 min later, in the afternoon and evening over four nonconsecutive days. SES-cortisol phenotypic associations were specific to the adolescence period. Specifically, higher awakening cortisol levels were detected in wealthier backgrounds, whereas higher cortisol awakening response (CAR) and diurnal changes were present at both ends of the SES continuum. Moreover, smaller genetic contributions emerged for awakening cortisol in youth from poorer compared to wealthier backgrounds. The results suggest that the relative contribution of inherited factors to awakening cortisol secretion may be enhanced or suppressed depending on the socio-family context, which may help to decipher the mechanisms underlying later adjustment.

Abstract
Adversity exposures in the prenatal and postnatal period are associated with an increased risk for psychopathology, which can be perpetuated across generations. Nonhuman animal research highlights the gut microbiome as a putative biological mechanism underlying such generational risks. In a sample of 450 mother-child dyads living in Singapore, we examined associations between three distinct adversity exposures experienced across two generations-maternal childhood maltreatment, maternal prenatal anxiety, and second-generation children's exposure to stressful life events-and the gut microbiome composition of second-generation children at 2 y of age. We found distinct differences in gut microbiome profiles linked to each adversity exposure, as well as some nonaffected microbiome features (e.g., beta diversity). Remarkably, some of the microbial taxa associated with concurrent and prospective child socioemotional functioning shared overlapping putative functions with those affected by adversity, suggesting that the intergenerational transmission of adversity may have a lasting impact on children's mental health via alterations to gut microbiome functions. Our findings open up a new avenue of research into the underlying mechanisms of intergenerational transmission of mental health risks and the potential of the gut microbiome as a target for intervention.

The Association of the Hypothalamic-Pituitary-Adrenal Axis with Appetite Regulation in Children with Fetal Alcohol Spectrum Disorders (FASDs). Nutrients 2023; 15:nu15061366. [PMID: 36986097 PMCID: PMC10053353 DOI: 10.3390/nu15061366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 03/08/2023] [Accepted: 03/09/2023] [Indexed: 03/14/2023] Open
Abstract
Prenatal alcohol exposure causes growth impairment and a wide range of developmental, physical, and cognitive disorders in children, collectively referred to as fetal alcohol spectrum disorders (FASDs). In the course of FASDs, abnormalities can also affect eating behavior and nutritional status, but these problems have received little attention. Therefore, the aim of our study was to determine the levels of hormones involved in the action of the hypothalamic–pituitary–adrenal axis: proopiomelanocortin (POMC), cortisol, and adrenocorticotropic hormone (ACTH), in the serum of patients with FASDs. To our knowledge, none of these hormones studied have yet been evaluated in FASDs to date. We investigated 62 FASD patients and 23 healthy controls by applying an enzyme-linked immunosorbent method (ELISA). Fasting POMC levels were significantly lower in patients with FASDs (10.97 vs. 18,57 ng/mL, p = 0.039) compared to controls. However, there were no differences in cortisol concentrations. Additionally, the sex and subgroup status (fetal alcohol syndrome (FAS), neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE), and FASD risk) did not affect hormone levels. POMC was positively correlated with some clinical parameters such as age, BMI percentile, carbohydrate biomarkers, and ACTH. A positive correlation was observed between ACTH and cortisol levels, as well as ACTH and cholesterol levels. Data analysis showed no HPA axis abnormalities in the form of elevated serum cortisol and ACTH levels. Differences in POMC concentration may indicate the involvement and/or impairment of central nervous system structures in hormonal alterations in FASD individuals, caused by prenatal alcohol exposure. Hormonal dysregulation in FASDs can contribute to reduced growth and development, as well as many other disturbed processes, including neurological/neurodevelopmental dysfunctions. Further insightful studies involving a larger group of patients are needed to determine the potential impact of the measured hormones.

Abstract
Sex differences in alcohol use and abuse are pervasive and carry important implications for the prevention and treatment of alcohol use disorder (AUD), yet insight into underlying sexually dimorphic mechanisms is limited. Growing experimental and clinical evidence points to an important influence of circadian rhythms and circadian clock genes in the control of alcohol drinking behavior and AUD. Sex differences in the expression of circadian rhythms and in the molecular circadian clock that drive these rhythms have been reported in humans and animals. While studying the role of striatal circadian clock gene expression in the control of affective and goal-directed behaviors, we uncovered a novel sexually dimorphic function of the clock genes Bmal1 and Per2 in the control of voluntary alcohol consumption in mice, which may contribute to sex differences in alcohol drinking behavior. In this mini review, we briefly discuss relevant literature on AUD, circadian rhythms and clock genes, and on sex differences in these domains, and describe our own findings on clock genes as sexually dimorphic regulators of alcohol drinking behavior in mice.

Abstract
BACKGROUND Fetal alcohol spectrum disorder (FASD) resulting from prenatal alcohol exposure (PAE) is a common neurodevelopmental disorder, but substantial interindividual heterogeneity complicates timely and accurate assessment, diagnosis, and intervention. The current study aimed to identify classes of children and adolescents with PAE assessed for FASD according to their pattern of significant neurodevelopmental functioning across 10 domains using latent class analysis (LCA), and to characterize these subgroups across clinical features. METHODS Data from the Canadian National FASD Database, a large ongoing repository of anonymized clinical data received from diagnostic clinics across Canada, was analyzed using a retrospective cross-sectional cohort design. The sample included 1440 children and adolescents ages 6 to 17 years (M = 11.0, SD = 3.5, 41.7% female) with confirmed PAE assessed for FASD between 2016 and 2020. RESULTS Results revealed an optimal four-class solution. The Global needs group was characterized by high overall neurodevelopmental impairment considered severe in nature. The Regulation and Cognitive needs groups presented with moderate but substantively distinguishable patterns of significant neurodevelopmental impairment. The Attention needs group was characterized by relatively low probabilities of significant neurodevelopmental impairment. Both the Global and Regulation needs groups also presented with the highest probabilities of clinical needs, further signifying potential substantive differences in assessment and intervention needs across classes. CONCLUSIONS Four relatively distinct subgroups were present in a large heterogeneous sample of children and adolescents with PAE assessed for FASD in Canada. These findings may inform clinical services by guiding clinicians to identify distinct service pathways for these subgroups, potentially increasing access to a more personalized treatment approach and improving outcomes.

Abstract
OBJECTIVE Individuals with fetal alcohol spectrum disorder (FASD) experience a range of complex neurodevelopmental, psychological, and socioenvironmental vulnerabilities. There is growing evidence that suicidal ideation, attempts, and death by suicide are significant concerns within this population. In this study, we (1) determined the rate of suicidal ideation/attempts in a large group of individuals with prenatal alcohol exposure (PAE) who were assessed for FASD in Canada and (2) investigated the associations between suicidal ideation/attempts and select demographic and biopsychosocial factors in this group. METHOD A secondary analysis of data from Canada's National FASD Database, a national repository of clinical information gathered through FASD assessment and diagnostic clinics across the country, was conducted. Descriptive analyses, chi-square/Fisher's exact tests, and binary logistic regression were used to examine demographic and biopsychosocial variables and their associations with suicidality. RESULTS In our sample of 796 participants (Mage = 17.7 years, range = 6-59; 57.6% male) assessed for FASD, 25.9% were reported to experience suicidal ideation/attempts. Numerous demographic and biopsychosocial factors were found to be significantly associated with suicidal ideation/attempts. The strongest associations with suicidal ideation/attempts were substance use, history of trauma/abuse, and impaired affect regulation. CONCLUSIONS With this study, we contribute to the emerging evidence of elevated risk of suicidality among individuals with PAE/FASD and improve our understanding of factors that may exacerbate this risk. Findings have relevance for improving screening, prevention, and proactive treatment approaches for individuals with PAE and FASD, their families, and wider support systems.

Abstract
BACKGROUND There is a paucity of prospective longitudinal studies examining the associations between maternal use of alcohol and tobacco during pregnancy and the risk of cannabis use in offspring. The aim of this study was to examine the association between prenatal alcohol and tobacco exposures and offspring cannabis use. METHODS Data were from the Raine Study, a longitudinal prospective birth cohort based in Western Australia. Cannabis use at 17 years of age was measured with a self-reported questionnaire developed to capture risky behaviors in adolescents. Associations between prenatal alcohol and tobacco exposures and the risk of cannabis use in offspring were examined using log-binomial regression models, computing relative risk (RR). We also computed the E-values (E) to estimate the extent of unmeasured confounding. RESULTS After adjusting for potential confounders, we observed increased risks of cannabis use in offspring exposed to first trimester prenatal alcohol use (RR = 1.38, 95% CI: 1.09-1.75; E = 2.10, CI:1.40) and tobacco use (RR = 1.42, 95% CI: 1.08-1.86; E = 2.19, CI:1.37) as well as third trimester prenatal alcohol use (RR = 1.39, 95% CI: 1.09-1.79; E = 2.13, CI:1.40) and tobacco use (RR = 1.39, 95% CI: 1.09-1.79; E = 2.21, CI:1.34]. We also noted dose-response associations in which risk estimates in offspring increased with the level of exposures to prenatal alcohol and tobacco use. CONCLUSION These findings provide epidemiological evidence for effects of prenatal alcohol and tobacco exposures on offspring cannabis use. Although these results should be confirmed by other studies, the present study adds to the mounting evidence suggesting that women should be encouraged to abstain from alcohol and tobacco during pregnancy.

Abstract
Fetal alcohol spectrum disorder (FASD) is a multifaceted disability, characterized not only by brain- and body-based challenges, but also high rates of environmental adversity, lifelong difficulties with daily living, and distinct sociocultural considerations. FASD is one of the most common neurodevelopmental disabilities in the Western world and associated with significant social and economic costs. It is important to understand the complexities of FASD and the ways in which FASD requires unique consideration in research, practice, and policy. In this article, we discuss our perspectives on factors that distinguish FASD from other disabilities in terms of complexity, co-occurrence, and magnitude. We provide an overview of select literature related to FASD as a socially rooted disability with intergenerational impacts and multiple layers of stigma. These social issues are intertwined with notable experiences of adversity across the lifespan and high rates of co-occurring health concerns for individuals with FASD, all of which present unique challenges for individuals, caregivers, families, service providers, and policy makers. Understanding these factors is the first step in developing and implementing specialized initiatives in support of positive outcomes for individuals with FASD and their families. Future directions are proposed for advancing research, practice, and policy, and responding to the unique complexities of FASD.

Abstract
This study examined whether resilience capacity moderates the association of daily perceived stress and affect with cortisol diurnal slope among relocated emerging adults. Relocated undergraduates (N = 98; aged 18-25 years) were recruited from three groups: Resilient, Vulnerable, and Control. The Resilient group required Risky Family Questionnaire (RFQ) scores ≥ 29 and Brief Resilience Scale (BRS) scores ≥ 3.6. The Vulnerable group required RFQ scores ≥ 29 and BRS scores ≤ 3. The comparison Control group required RFQ scores ≤ 21 and T-scores < 60 on PROMIS anxiety and depression symptoms. Mixed-effects models were used to test the unique associations of perceived stress, negative affect, and positive affect x group interactions (predictors) on diurnal cortisol slope (outcome) across 14 consecutive days. The Resilient group did not moderate the associations between daily stress or affect on cortisol diurnal slope. Instead, both the Resilient and Vulnerable groups with early family risk, showed a steeper diurnal slope unique to higher stress and a flatter slope unique to higher negative affect. Results suggest that riskier early family life was significantly associated with altered cortisol diurnal slope outcomes to stress (i.e., demand) and negative affect (i.e., distress). These associations were not attenuated by current resilience capacity.

Abstract
Prenatal adversity or stress can have long-term consequences on developmental trajectories and health outcomes. Although the biological mechanisms underlying these effects are poorly understood, epigenetic modifications, such as DNA methylation, have the potential to link early-life environments to alterations in physiological systems, with long-term functional implications. We investigated the consequences of two prenatal insults, prenatal alcohol exposure (PAE) and food-related stress, on DNA methylation profiles of the rat brain during early development. As these insults can have sex-specific effects on biological outcomes, we analyzed epigenome-wide DNA methylation patterns in prefrontal cortex, a key brain region involved in cognition, executive function, and behavior, of both males and females. We found sex-dependent and sex-concordant influences of these insults on epigenetic patterns. These alterations occurred in genes and pathways related to brain development and immune function, suggesting that PAE and food-related stress may reprogram neurobiological/physiological systems partly through central epigenetic changes, and may do so in a sex-dependent manner. Such epigenetic changes may reflect the sex-specific effects of prenatal insults on long-term functional and health outcomes and have important implications for understanding possible mechanisms underlying fetal alcohol spectrum disorder and other neurodevelopmental disorders.

Early maternal loss leads to short- but not long-term effects on diurnal cortisol slopes in wild chimpanzees. eLife 2021; 10:e64134. [PMID: 34133269 PMCID: PMC8208813 DOI: 10.7554/elife.64134] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 05/19/2021] [Indexed: 12/18/2022] Open
Abstract
The biological embedding model (BEM) suggests that fitness costs of maternal loss arise when early-life experience embeds long-term alterations to hypothalamic-pituitary-adrenal (HPA) axis activity. Alternatively, the adaptive calibration model (ACM) regards physiological changes during ontogeny as short-term adaptations. Both models have been tested in humans but rarely in wild, long-lived animals. We assessed whether, as in humans, maternal loss had short- and long-term impacts on orphan wild chimpanzee urinary cortisol levels and diurnal urinary cortisol slopes, both indicative of HPA axis functioning. Immature chimpanzees recently orphaned and/or orphaned early in life had diurnal cortisol slopes reflecting heightened activation of the HPA axis. However, these effects appeared short-term, with no consistent differences between orphan and non-orphan cortisol profiles in mature males, suggesting stronger support for the ACM than the BEM in wild chimpanzees. Compensatory mechanisms, such as adoption, may buffer against certain physiological effects of maternal loss in this species.

Abstract
BACKGROUND Individuals with Fetal Alcohol Spectrum Disorder (FASD) and prenatal alcohol exposure (PAE) face elevated rates of postnatal environmental adversity across the lifespan. OBJECTIVE We explored early adversity among children and adolescents with PAE. PARTICIPANTS AND SETTING Our sample included 333 children and adolescents with PAE assessed at a Canadian FASD diagnostic clinic, 66% of whom were diagnosed with FASD. METHODS Data were collected retrospectively via record review, and adversity was measured using the Adverse Childhood Experiences Questionnaire (ACE-Q). RESULTS Participants experienced high levels of adversity (mean ACE score of 3.4), which increased with age, mental health comorbidity, and number of living placements. Common ACEs included: not being raised by both biological parents (97.3%), caregiver disruption (88.5%), and exposure to household substance use (69.7%). Females had significantly higher rates of sexual abuse than males (p < .001, ø = -0.18). There was no difference in total ACE scores between participants diagnosed with FASD versus those not diagnosed, but participants with FASD were less likely to live with both biological parents (p < .001, ø = .19) or to have been exposed to household mental health problems (p = .007, ø = -0.15). CONCLUSIONS Children and adolescents with PAE experience high rates of early adversity. Practice and policy initiatives are needed to improve early detection of ACEs among children with PAE, and of PAE among children with ACEs. Targeted supports are needed to strengthen the early caregiving environment and mitigate the risks of adversity to support healthy outcomes for individuals with PAE and FASD.

An investigation of the link between prenatal alcohol exposure and sleep problems across childhood. Drug Alcohol Depend 2021; 218:108412. [PMID: 33262002 DOI: 10.1016/j.drugalcdep.2020.108412] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 11/01/2020] [Accepted: 11/02/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To investigate the association between dose and frequency of prenatal alcohol exposure (PAE) and sleep problems in children, after controlling for established risk factors for sleep problems. METHODS Data from the birth cohort of the Longitudinal Study of Australian Children (LSAC) was used. Mothers of 3447 children provided information on alcohol consumption during pregnancy, children's sleep problems from 2- to 9-years, and potential confounders associated with sleep problems. Children were classified into PAE groups based on distinct patterns of maternal drinking during pregnancy: abstinent, occasional, low, moderate, and heavy. The effect of PAE on the number and persistence of sleep problems across childhood (2-9 years) was examined. RESULTS After controlling for multiple covariates that impact sleep, children with heavy PAE had 1.13 more sleep problems across childhood (2-9 years) relative to children whose mothers were abstainers, in particular 0.37 more at 2- to 3-years (0.504, 95 % CI 0.053, 0.956), and 0.34 more at 6- to 7-years (0.847, 95 % CI 0.299, 1.396). Compared to children of abstainers, heavy PAE increases the probability of having persistent sleep problems from 2- to 9-years by 22.57 %. No negative associations between moderate or low PAE and sleep were observed. Parenting, family, economic, and child health factors also significantly affected child sleep. CONCLUSION Heavy PAE was associated with significantly more sleep problems across childhood and a higher probability of reporting persistent sleep problems, relative to children with no PAE. Implications for the understanding and management of sleep in young children with PAE and FASD are discussed.

Abstract
Individuals with fetal alcohol spectrum disorder (FASD) experience remarkably high rates of mental health and substance use challenges, beginning early in life and extending throughout adulthood. Proactive intervention can help to mitigate some of these negative experiences. Although the literature on FASD intervention is growing, there is currently a lack of consolidated evidence on interventions that may improve mental health and substance use outcomes in this population. Informed by a life course perspective, we undertook a systematic review of the literature to identify interventions that improve mental wellness through all developmental stages for people with prenatal alcohol exposure (PAE) and FASD. A total of 33 articles were identified, most of which were focused on building skills or strategies that underlie the well‐being of children with PAE and FASD and their families. Other interventions were geared toward supporting child and family wellness and responding to risk or reducing harm. There was a notable lack of interventions that directly targeted mental health and substance use challenges, and a major gap was also noted in terms of interventions for adolescents and adults. Combined, these studies provide preliminary and emerging evidence for a range of intervention approaches that may support positive outcomes for individuals with FASD across the life course.

Positive Economic, Psychosocial, and Physiological Ecologies Predict Brain Structure and Cognitive Performance in 9-10-Year-Old Children. Front Hum Neurosci 2020; 14:578822.

Abstract
While low socioeconomic status (SES) introduces risk for developmental outcomes among children, there are an array of proximal processes that determine the ecologies and thus the lived experiences of children. This study examined interrelations between 22 proximal measures in the economic, psychosocial, physiological, and perinatal ecologies of children, in association with brain structure and cognitive performance in a diverse sample of 8,158 9-10-year-old children from the Adolescent Brain Cognitive Development (ABCD) study. SES was measured by the income-to-needs ratio (INR), a measure used by federal poverty guidelines. Within the ABCD study, in what is one of the largest and most diverse cohorts of children studied in the United States, we replicate associations of low SES with lower total cortical surface area and worse cognitive performance. Associations between low SES (<200% INR) and measures of development showed the steepest increases with INR, with apparent increases still visible beyond the level of economic disadvantage in the range of 200-400% INR. Notably, we found three latent factors encompassing positive ecologies for children across the areas of economic, psychosocial, physiological, and perinatal well-being in association with better cognitive performance and the higher total cortical surface area beyond the effects of SES. Specifically, latent factors encompassing youth perceived social support and perinatal well-being were positive predictors of developmental measures for all children, regardless of SES. Further, we found a general latent factor that explained relationships between 20 of the proximal measures and encompassed a joint ecology of higher social and economic resources relative to low adversity across psychosocial, physiological, and perinatal domains. The association between the resource-to-adversity latent factor and cognitive performance was moderated by SES, such that for children in higher SES households, cognitive performance progressively increased with these latent factor scores, while for lower SES, cognitive performance increased only among children with the highest latent factor scores. Our findings suggest that both positive ecologies of increased access to resources and lower adversity are mutually critical for promoting better cognitive development in children from low SES households. Our findings inform future studies aiming to examine positive factors that influence healthier development in children.

Abstract
BACKGROUND Drinking alcohol during pregnancy is considered a risk factor for child development; however, child biomarkers of prenatal alcohol exposure have been rarely studied. We examined whether a meconium alcohol metabolite (ethyl glucuronide, EtG) was associated with child cortisol concentrations at primary school age. METHODS For 137 children, prenatal alcohol exposure was operationalized by the meconium biomarker EtG and by maternal self-reports during pregnancy. Two EtG cut-offs (EtG ≥10 ng/g and EtG ≥112 ng/g) were applied. Cortisol concentrations were measured in saliva and hair samples. RESULTS Children with EtG ≥10 ng/g showed significantly reduced hair cortisol concentrations (HCCs) (p = .050, η p 2 = 0.042). For children with EtG ≥112 ng/g, the cortisol awakening response (CAR) was significantly decreased (p = .025, η p 2 = 0.070). These effects were also present in correlational analyses with continuous EtG data, speaking for partly dose-dependent effects. Especially, within the EtG ≥112 ng/g group, the basal (CAR: rp = -.642, p = .120) and cumulative (HCC: rp = -.660, p = .107) cortisol parameters were associated with child emotional symptoms at medium effect size. CONCLUSIONS The present study showed both the biological association of intrauterine alcohol exposure with the cortisol stress system, partly dose-dependent, and the functional association with emotional and behavioral symptoms.

Abstract
BACKGROUND Infants with prenatal substance exposure are at increased risk for developmental problems, with self-regulatory challenges being some of the most pronounced. The current study aimed to investigate the extent to which prenatal substance exposure (alcohol, opioids) impacts infant self-regulation during a relational stressor and the association between self-regulation and infant affect. METHODS Participants were 100 mother-child dyads recruited prenatally (Mean = 23.8 gestational weeks) and completed the Still Face Paradigm (SFP) when infants were 5 to 8 months of age (Mean = 6.9 months) as part of an ENRICH prospective birth cohort study. Based on prospective repeated assessment of maternal substance use in pregnancy, infants were grouped into: 1) Unexposed controls; 2) Alcohol-exposed; 3) Opioid-exposed due to maternal use of medications for opioid use disorder (MOUD) with or without other opioids; 4) MOUD and alcohol. Infant stress reactivity (negative affect) and self-regulation were assessed during the validated 5-episode SFP. Mixed effects linear models were used to analyze differences in the percent of self-regulation and percent of negative affect among the study groups across SFP episodes, as well as the group-by-self-regulation interaction with respect to infant negative affect. RESULTS The MOUD+Alcohol group demonstrated significantly lower self-regulation at baseline compared to controls (p < 0.05). There was a significant group-by-self-regulation interaction (p = 0.028). Higher self-regulation was associated with lower negative affect across SFP episodes in the MOUD+Alcohol group (p = 0.025) but not other groups. CONCLUSION Self-regulation skills are particularly important for emotional modulation in infants with prenatal polysubstance exposure, highlighting the development of these skills as a promising intervention target.

Abstract
OBJECTIVES A number of commonly used performance validity tests (PVTs) may be prone to high failure rates when used for individuals with severe neurocognitive deficits. This study investigated the validity of 10 PVT scores in justice-involved adults with fetal alcohol spectrum disorder (FASD), a neurodevelopmental disability stemming from prenatal alcohol exposure and linked with severe neurocognitive deficits. METHOD The sample comprised 80 justice-involved adults (ages 19-40) including 25 with confirmed or possible FASD and 55 where FASD was ruled out. Ten PVT scores were calculated, derived from Word Memory Test, Genuine Memory Impairment Profile, Advanced Clinical Solutions (Word Choice), the Wechsler Adult Intelligence Scale - Fourth Edition (Reliable Digit Span and age-corrected scaled scores (ACSS) from Digit Span, Coding, Symbol Search, Coding - Symbol Search, Vocabulary - Digit Span), and the Wechsler Memory Scale - Fourth Edition (Logical Memory II Recognition). RESULTS Participants with diagnosed/possible FASD were more likely to fail any single PVT, and failed a greater number of PVTs overall, compared to those without FASD. They were also more likely to fail based on Word Memory Test, Digit Span ACSS, Coding ACSS, Symbol Search ACSS, and Logical Memory II Recognition, compared to controls (35-76%). Across both groups, substantially more participants with IQ <70 failed two or more PVTs (90%), compared to those with an IQ ≥70 (44%). CONCLUSIONS Results highlight the need for additional research examining the use of PVTs in justice-involved populations with FASD.

Abstract
BACKGROUND Individuals with fetal alcohol spectrum disorder (FASD) experience a range of problems in their cognitive, affective, and physical functioning following prenatal alcohol exposure (PAE), in addition to multiple complex difficulties in daily living that impact well-being. Using the Canadian National FASD Database, we sought to profile a range of difficulties in daily living, along with risk factors, in a large cross-sectional cohort of adolescents, transition-aged youth, and adults with PAE, of which a subset was ultimately diagnosed with FASD. METHODS We summarized data for 9 current difficulties in daily living reported at the time of diagnostic assessment for 726 individuals with PAE assessed at 26 FASD diagnostic clinics across Canada, including 443 adolescents (12 to 17 years), 135 transition-aged youth (18 to 24 years), and 148 adults (25 to 60 years). Difficulties included problems related to school disruption, employment, independent living needs, supportive or sheltered housing, legal problems with victimization, legal problems with offending, incarceration, alcohol misuse, and other substance misuse. Risk factors included age, gender, living placement, postnatal trauma, and neurodevelopmental impairment. RESULTS Across the full PAE sample, adolescents, transition-aged youth, and adults presented with high rates of difficulties in daily living, including independent living support needs (63%), alcohol misuse (38%), other substance misuse (46%), employment problems (37%), legal problems with offending (30%), assisted or sheltered housing (21%), school disruption (18%), legal problems with victimization (4%), and incarceration (3%). Difficulty rates were similar for those with FASD irrespective of diagnosis (e.g., with or without sentinel facial features), but rates greater for adults, and those with low overall intellectual functioning (IQ < 70). Controlling for age and IQ, cumulative difficulty was independently associated with gender, living placement, and neurodevelopmental impairment. CONCLUSIONS Adolescents, transition-aged youth, and adults with FASD experienced a range of substantial and complex difficulties at the time of their diagnostic assessment, signaling a high level of service needs. These findings underscore the importance of developmentally informed assessment continued through childhood, as well as ongoing functional and needs-based service provision as youth with FASD transition to adulthood and beyond.

Abstract
BACKGROUND High levels of anxiety and sleep problems are common features of Fetal Alcohol Spectrum Disorders (FASD). The strong association between sleep and anxiety has been documented in typically developing (TD) populations and is thought to be bidirectional. The association between sleep and anxiety in children with FASD has not yet been examined. METHODS Caregivers of children with FASD (n = 91) and TD children (n = 103) aged 6-16 completed the Children's Sleep Habits Questionnaire (CSHQ), Spence Children's Anxiety Scale (SCAS), and a background questionnaire. Hierarchical multiple regression analyses, group comparisons and ANCOVA interaction models were used to test the associations between sleep and anxiety within and between the two groups. RESULTS Sleep disturbances and anxiety were at clinical levels for the majority of the FASD group, and significantly higher in the FASD group than the TD group. After controlling for age and sex, 27 % of the variance in anxiety scores in TD children was attributable to sleep problems, and 33 % in children with FASD. CONCLUSION This study highlights associations between parent-reported sleep and anxiety in FASD. Sleep disturbances were significant predictors of anxiety in both children with FASD and in TD children. Given the importance of sleep to healthy neurodevelopment, there is a pressing need for sleep intervention studies in children with FASD. Early identification and intervention for sleep problems in this condition should be a therapeutic priority.

Abstract
AIMS Individuals with fetal alcohol spectrum disorder (FASD) frequently have challenges with regulating emotional arousal, or affect regulation (AR), and experience high rates of mental health disorders. This study examined children and adults with FASD to investigate the relationship between AR impairment and several mental health problems and diagnoses. METHODS Data from the Canadian national FASD database was used for analysis. Seven mental health diagnoses, including attention-deficit/hyperactivity disorder, post-traumatic stress disorder, conduct disorder, attachment disorder, intellectual disability, and language disorder were examined. A history of suicidality was also examined. The prevalence of these mental health problems in individuals with and without AR impairment was compared. RESULTS Individuals with FASD and AR impairment were significantly more likely to be diagnosed with conduct disorder (OR 4.8), attachment disorder (OR 6.1), or post-traumatic stress disorder (OR 8.1) when compared to those without AR impairment. They were also more likely to have a history of suicidality (OR 8.6). AR impairment was most commonly found in those with greater overall neurodevelopmental impairment. Having AR impairment was associated with receiving a diagnosis of FASD at a later age, but was not related to gender, intellectual disability, or language disorder. CONCLUSION AR impairment is strongly related to several mental health diagnoses in those with FASD and presents some promising possibilities for targeted early intervention.

Abstract
INTRODUCTION Clinical research and studies using animal models have revealed a complex and relatively under-explored interaction between prenatal alcohol exposure (PAE) and alterations in sleep-wake behaviors. OBJECTIVES To utilize a structured naturalistic observation-based methodology, consisting of descriptive elements, to provide insight into possible links between altered sleep and disruptive daytime presentations in children and adolescents with fetal alcohol spectrum disorder (FASD). To apply a similar structured behavioral observation protocol in a PAE animal model to compare outcomes from the experimental and clinical studies utilizing naturalistic observational methodology. METHODS Forty pediatric patients with FASD (1.8-17.5 yrs, median age 9.4 yrs) and chronic sleep problems were assessed. In the PAE animal model, male offspring from PAE, Pair-Fed (PF), and ad libitum-fed Control (C) groups (n = 8/group) were assessed in the juvenile/preadolescent (23-25 days of age) and adolescent/pubertal (35-36 days of age) periods. RESULTS In the clinical setting, we found that 95% of children with FASD showed disruptive or externalizing behaviors, 73% showed internalizing behaviors, 93% had circadian rhythm sleep disorders, all had chronic insomnia, and 85% had restless sleep, often with tossing/turning/kicking movements indicative of non-restorative sleep with hypermotor events. In the daytime, individuals showed excessive daytime sleepiness as well as hyperactive/hyperkinetic behaviors, an urge-to-move, and involuntary movements suggestive of hyperarousability. Alterations in sleep/wake behaviors in the PAE animal model paralleled the clinical data in many aspects, demonstrating greater sleep latencies, less total time asleep, more total time awake and longer awake bouts, more position changes, more time in transition, and longer transition bouts in PAE compared to PF and/or control animals. CONCLUSIONS Thus, our findings provide support for the power and validity of naturalistic observational paradigms in revealing dysregulated sleep-wake behaviors and their association and/or exacerbating relationship with day and nighttime behavioral problems, such as disruptive behaviors, externalizing and internalizing disorders, and daytime sleepiness.

Abstract
BACKGROUND Individuals with fetal alcohol spectrum disorder (FASD) experience a range of cognitive, affective, and physical deficits following prenatal alcohol exposure. They are thought to be overrepresented in criminal justice settings. However, limited evidence is available to inform prevalence. We sought to estimate the prevalence of FASD in a Northern Canadian correctional population. METHODS Using an active case ascertainment approach we recruited a representative sample of 80 justice-involved adults (ages 18-40, 85% male) over an 18-month period from 2013 to 2015. Participants completed interdisciplinary clinical assessments comprising medical and psychological evaluations that adhered to the 2005 Canadian FASD Diagnostic Guidelines. RESULTS We identified a high rate of FASD (17.5, 95% CI [9.2, 25.8%]) in this sample, and this rate could have been as high as 31.2% with confirmation of prenatal alcohol exposure. Most participants in this study presented with significant neurodevelopmental and cognitive deficits in at least two domains of functioning, irrespective of diagnosis, with only five of 80 participants (6.3%) demonstrating no cognitive impairment. CONCLUSIONS Findings showed disproportionately high estimated FASD prevalence in this representative sample compared to general population estimates in both Canada and the U.S. (2-5%), underscoring the need for improved FASD screening and diagnosis in correctional settings, and education for clinicians working in the justice context. Strengthened health prevention and intervention efforts to support the needs of individuals with FASD outside the criminal justice context are needed.

Abstract
Background: Prenatal alcohol exposure (PAE) can alter the development of neurobiological systems, leading to lasting neuroendocrine, neuroimmune, and neurobehavioral deficits. Although the etiology of this reprogramming remains unknown, emerging evidence suggests DNA methylation as a potential mediator and biomarker for the effects of PAE due to its responsiveness to environmental cues and relative stability over time. Here, we utilized a rat model of PAE to examine the DNA methylation profiles of rat hypothalami and leukocytes at four time points during early development to assess the genome-wide impact of PAE on the epigenome and identify potential biomarkers of PAE. Our model of PAE resulted in blood alcohol levels of ~80-150 mg/dl throughout the equivalent of the first two trimesters of human pregnancy. Hypothalami were analyzed on postnatal days (P) 1, 8, 15, 22 and leukocytes at P22 to compare central and peripheral markers. Genome-wide DNA methylation analysis was performed by methylated DNA immunoprecipitation followed by next-generation sequencing. Results: PAE resulted in lasting changes to DNA methylation profiles across all four ages, with 118 differentially methylated regions (DMRs) displaying persistent alterations across the developmental period at a false-discovery rate (FDR) < 0.05. In addition, 299 DMRs showed the same direction of change in the hypothalamus and leukocytes of P22 pups at an FDR < 0.05, with some genes overlapping with the developmental profile findings. The majority of these DMRs were located in intergenic regions, which contained several computationally-predicted transcription factor binding sites. Differentially methylated genes were generally involved in immune function, epigenetic remodeling, metabolism, and hormonal signaling, as determined by gene ontology analyses. Conclusions: Persistent DNA methylation changes in the hypothalamus may be associated with the long-term physiological and neurobehavioral alterations in observed in PAE. Furthermore, correlations between epigenetic alterations in peripheral tissues and those in the brain will provide a foundation for the development of biomarkers of fetal alcohol spectrum disorder (FASD). Finally, findings from studies of PAE provide important insight into the etiology of neurodevelopmental and mental health disorders, as they share numerous phenotypes and comorbidities.

Abstract
The present review revisits three hypothesized models that potentially could explain how prenatal maternal stress influences fetal development, birth outcomes, and subsequent developmental psychopathology. These models were mostly based on animal models, and new evidence for these models from human studies is evaluated. Furthermore, divergent trajectories from prenatal exposure to adversities to offspring affected outcomes are reviewed, including the comparison of studies on prenatal maternal stress with research on maternal substance use and maternal malnutrition during pregnancy. Finally, new directions in research on the mechanism underlying prenatal stress effects on human offspring is summarized. While it is concluded that there is abundant evidence for the negative associations between prenatal maternal stress and offspring behavioral, brain, and psychopathological outcomes in humans, there is no consistent evidence for specific mechanisms or specific outcomes in relation to stress exposure in utero. Rather, principles of multifinality and equifinality best describe the consequences for the offspring, suggesting a generic vulnerability and different pathways from prenatal adversities to developmental psychopathology, which complicates the search for underlying mechanisms. New and promising directions for research are provided to get a better understanding of how prenatal stress gets under the skin to affect fetal development.

Abstract
BACKGROUND Studies in clinical populations and preclinical models have shown that prenatal alcohol exposure (PAE) is associated with impairments in the acquisition, consolidation and recall of information, with deficits in hippocampal formation-dependent learning and memory being a common finding. The glucocorticoid receptor (GR), mineralocorticoid receptor (MR), and extracellular signal-regulated kinase 2 (ERK2) are key regulators of hippocampal formation development, structure and functioning and, thus, are potential mediators of PAE's effects on this brain region. In the present studies, we employed a well-characterized mouse model of PAE to identify biochemical mechanisms that may underlie activity-dependent learning and memory deficits associated with PAE. METHODS Mouse dams consumed either 10% (w/v) ethanol in 0.066% (w/v) saccharin (SAC) or 0.066% (w/v) SAC alone using a limited (4-h) access, drinking-in-the-dark paradigm. Male and female offspring (∼180-days of age) were trained using a delay conditioning procedure and contextual fear responses (freezing behavior) were measured 24 h later. Hippocampal formation tissue and blood were collected from three behavioral groups of animals: 20 min following conditioning (conditioning only group), 20 min following the re-exposure to the context (conditioning plus re-exposure group), and behaviorally naïve (naïve group) mice. Plasma corticosterone levels were measured by enzyme immunoassay. Immunoblotting techniques were used to measure protein levels of the GR, MR, ERK1 and ERK2 in nuclear and membrane fractions prepared from the hippocampal formation. RESULTS Adult SAC control male and female mice displayed similar levels of contextual fear. However, significant sex differences were observed in freezing exhibited during the conditioning session. Compared to same-sex SAC controls, male and female PAE mice demonstrated context fear deficits While plasma corticosterone concentrations were elevated in PAE males and females relative to their respective SAC naïve controls, plasma corticosterone concentrations in the conditioning only and conditioning plus re-exposure groups were similar in SAC and PAE animals. Relative to the respective naïve group, nuclear GR protein levels were increased in SAC, but not PAE, male hippocampal formation in the conditioning only group. In contrast, no difference was observed between nuclear GR levels in the naïve and conditioning plus re-exposure groups. In females, nuclear GR levels were significantly reduced by PAE but there was no effect of behavioral group or interaction between prenatal treatment and behavioral group. In males, nuclear MR levels were significantly elevated in the SAC conditioning plus re-exposure group compared to SAC naïve mice. In PAE females, nuclear MR levels were elevated in both the conditioning only and conditioning plus re-exposure groups relative to the naïve group. Levels of activated ERK2 (phospho-ERK2 expressed relative to total ERK2) protein were elevated in SAC, but not PAE, males following context re-exposure, and a significant interaction between prenatal exposure group and behavioral group was found. No main effects or interactions of behavioral group and prenatal treatment on nuclear ERK2 were found in female mice. These findings suggest a sex difference in which molecular pathways are activated during fear conditioning in mice. CONCLUSIONS In PAE males, the deficits in contextual fear were associated with the loss of responsiveness of hippocampal formation nuclear GR, MR and ERK2 to signals generated by fear conditioning and context re-exposure. In contrast, the contextual fear deficit in PAE female mice does not appear to be associated with activity-dependent changes in GR and MR levels or ERK2 activation during training or memory recall, although an overall reduction in nuclear GR levels may play a role. These studies add to a growing body of literature demonstrating that, at least partially, different mechanisms underlie learning, memory formation and memory recall in males and females and that these pathways are differentially affected by PAE.

Abstract
The contribution of the early postnatal environment to the pervasive effects of prenatal alcohol exposure (PAE) is poorly understood. Moreover, PAE often carries increased risk of exposure to adversity/stress during early life. Dysregulation of immune function may play a role in how pre- and/or postnatal adversity/stress alters brain development. Here, we combine two animal models to examine whether PAE differentially increases vulnerability to immune dysregulation in response to early-life adversity. PAE and control litters were exposed to either limited bedding (postnatal day [PN] 8-12) to model early-life adversity or normal bedding, and maternal behavior and pup vocalizations were recorded. Peripheral (serum) and central (amygdala) immune (cytokines and C-reactive protein - CRP) responses of PAE animals to early-life adversity were evaluated at PN12. Insufficient bedding increased negative maternal behavior in both groups. Early-life adversity increased vocalization in all animals; however, PAE pups vocalized less than controls. Early-life adversity reduced serum TNF-α, KC/GRO, and IL-10 levels in control but not PAE animals. PAE increased serum CRP, and levels were even higher in pups exposed to adversity. Finally, PAE reduced KC/GRO and increased IL-10 levels in the amygdala. Our results indicate that PAE alters immune system development and both behavioral and immune responses to early-life adversity, which could have subsequent consequences for brain development and later life health.

Abstract
Accumulating evidence has revealed high rates of sleep disruption among children with fetal alcohol spectrum disorder (FASD). Multiple animal and clinical studies have found a clear association between sleep problems and prenatal alcohol exposure, and recent research is beginning to characterize the types and extent of sleep disruption in FASD. Nevertheless, sleep disruption in children with FASD often goes unrecognized or is treated without referring to an evidence base. Children's disrupted sleep interferes with parental sleep and increases caregiver burden, which is of particular importance for families raising children with FASD, a group with very high levels of caregiving stress. The literature supporting an association between sleep problems and deficits in emotional, behavioral, and cognitive function in children is compelling, but needs further investigation in children with FASD. This paper will review the current state of knowledge on sleep in FASD and recommend a rational approach to sleep interventions for affected children and their families.
