Background and Aims: In the neurobiological theory of attention, the orienting network mainly supports the temperamental regulatory function in infancy, with soothing methods such as visual attention distraction influencing its development. The attention distraction method chosen for soothing is thought to be influenced by maternal sensitivity, which has been found to decrease with poor maternal mental health. We hypothesize that the degree of maternal distress may affect the choice of attention distraction soothing method. Further, individual differences in being soothed by attention distraction will be associated with the temperamental regulation function in infancy/toddlerhood. Method: Structural equation modeling (SEM) was conducted on longitudinal data at 6 and 24 months on a sample (N = 1892) drawn from the sub‐cohort of the Japan Environment and Children's Study (JECS). Temperament was examined through the short Infant Behavior Questionnaire‐Revised (Japanese version) and the Early Childhood Behavior Questionnaire (Japanese version). Distress in caregivers was measured through the Kessler Psychological Distress Scale (Japanese version) at prenatal and 1‐year‐postnatal stages. Individual differences in using visual distraction soothing methods were also measured using tailor‐made items. Results: Postnatal maternal distress at 12 months was negatively related to the tendency to use visual attention distraction as a soothing method (β = −0.06, p = 0.006) at 24 months. When we applied the subscale of the temperamental regulatory factor in SEM, the more the mothers chose the distraction method for soothing, i.e., the more the toddlers experienced it, the higher their attention shifting scores (β = 0.07, p = 0.002). Conclusion: The findings support the view that caregivers' choice of method for distracting offspring's attention from distress may be associated with the development of self‐regulation during infancy and toddlerhood. Keynotes: In the neurobiological temperament model, the orienting attention network mainly supports the regulatory function in infancy, with soothing methods, including visual attention distraction, influencing its development.In the sub‐cohort of the Japan Environment and Children's Study, the relationship between maternal distress and mothers' choice of distraction as a soothing method and between the degree of being soothed by distraction and infants/toddlers' regulatory function were examined at 6 and 24 months (N = 1892).Higher maternal distress at 12 M postpartum was associated with fewer distraction methods, and more distraction at 24 M was associated with higher attention shifting at 24 M.

Background and objectives: The neurodevelopment of the offspring is suggested to be influenced by the maternal immune system's responses throughout pregnancy, which in turn is also vulnerable to maternal psychosocial stress conditions. Therefore, our main goal was to investigate whether maternal peripheral immunological biomarkers (IB) during two stages of gestation are associated with distinct neurodevelopmental trajectories in the first two years of life. As a second goal, we also explored the association between maternal distal (childhood) and proximal (gestation) stressful experiences and the immunological markers assessed during pregnancy. Methods: Maternal childhood trauma, depressive and anxiety symptoms, and peripheral IB (IFNγ, IL-10, IL1β, IL6, IL8, TNFα, EGF, IL13, IL17, IL1Ra and IL4) were measured at baseline (8–16 weeks of pregnancy) and at 30 weeks of pregnancy in 160 women. The participants had the blood samples collected from two randomized clinical trials conducted by the same team and methods in the same community. A Principal Component Analysis (PCA) was implemented to create meaningful composite variables that describe the cytokines joint variation. Finally, linear mixed-effects modeling was used to investigate the influence of inflammatory biomarkers, maternal childhood trauma, anxiety, and depressive symptoms on Bayley's III scores trajectories. Results: The IB profile during the 3rd trimester of pregnancy predicted the offspring's neurodevelopmental trajectories in the first two years of life. The components derived from PCA were important predictors and captured different immune responses, reflecting both pro- and anti-inflammatory states. Maternal stressful experiences did not correlate with the immunological markers. Although not a reliable predictor alone, maternal psychosocial stress at the 1st trimester of pregnancy interacted with the mother's immune response while predicting the neurodevelopmental scores during the first two years of life. Conclusions: Our results underscore the importance of the maternal immune response during pregnancy in shaping the neurodevelopmental trajectory of the offspring. Additionally, we observed that the maternal distress at the early stages of pregnancy has an incremental effect on the neurodevelopmental outcome but depends upon the immune response.

Maternal prenatal distress (PD), frequently defined as in utero prenatal stress exposure (PSE) to the developing fetus, influences the developing brain and numerous associations between PSE and brain structure have been described both in neonates and in older children. Previous studies addressing PSE-linked alterations in neonates’ brain activity have focused on connectivity analyses from predefined seed regions, but the effects of PSE at the level of distributed functional networks remains unclear. In this study, we investigated the impact of prenatal distress on the spatial and temporal properties of functional networks detected in functional MRI data from 20 naturally sleeping, term-born (age 25.85 ± 7.72 days, 11 males), healthy neonates. First, we performed group level independent component analysis (GICA) to evaluate an association between PD and the spatial configuration of the functional networks. Second, we search for an association with PD at the level of the stability of functional networks over time using leading eigenvector dynamics analysis (LEiDA). No statistically significant associations were detected at the spatial level for the GICA-derived networks. However, at the dynamic level, LEiDA revealed that maternal PD significantly decreased the stability of a frontoparietal network. These results imply that maternal PD may influence the stability of frontoparietal connections in neonatal brain network dynamics and adds to the cumulating evidence that frontal areas are especially sensitive to PSE. We advocate for early preventive intervention strategies regarding pregnant mothers. Nevertheless, future research venues are required to assess optimal intervention timing and methods for maximum benefit.

Maternal mental health may be considered a determining factor influencing fetal and child development. An essential factor with potentially negative consequences for a child's psychophysiological development is the presence of maternal distress during pregnancy and the postpartum period. The review is organized and presented to explore and describe the effects of anxiety, stress, and depression in pregnancy and the postpartum period on adverse child developmental outcomes. The neurobiology of maternal distress and the transmission mechanisms at the molecular level to the fetus and child are noted. In addition, the paper discusses the findings of longitudinal studies in which early child development is monitored concerning the presence of maternal distress in pregnancy and the postpartum period. This topic gained importance in the COVID-19 pandemic context, during which a higher frequency of maternal psychological disorders was observed. The need for further interdisciplinary research on the relationship between maternal mental health and fetal/child development was highlighted, especially on the biological mechanisms underlying the transmission of maternal distress to the (unborn) child, to achieve positive developmental outcomes and improve maternal and child well-being.

Milestones of brain development in mammals are completed before birth, which provide the prerequisite for cognitive and intellectual performances of the offspring. Prenatal challenges, such as maternal stress experience or infections, have been linked to impaired cognitive development, poor intellectual performances as well as neurodevelopmental and psychiatric disorders in the offspring later in life. Fetal microglial cells may be the target of such challenges and could be functionally modified by maternal markers. Maternal markers can cross the placenta and reach the fetus, a phenomenon commonly referred to as "vertical transfer." These maternal markers include hormones, such as glucocorticoids, and also maternal immune cells and cytokines, all of which can be altered in response to prenatal challenges. Whilst it is difficult to discriminate between the maternal or fetal origin of glucocorticoids and cytokines in the offspring, immune cells of maternal origin-although low in frequency-can be clearly set apart from offspring's cells in the fetal and adult brain. To date, insights into the functional role of these cells are limited, but it is emergingly recognized that these maternal microchimeric cells may affect fetal brain development, as well as post-natal cognitive performances and behavior. Moreover, the inheritance of vertically transferred cells across generations has been proposed, yielding to the presence of a microchiome in individuals. Hence, it will be one of the scientific challenges in the field of neuroimmunology to identify the functional role of maternal microchimeric cells as well as the brain microchiome. Maternal microchimeric cells, along with hormones and cytokines, may induce epigenetic changes in the fetal brain. Recent data underpin that brain development in response to prenatal stress challenges can be altered across several generations, independent of a genetic predisposition, supporting an epigenetic inheritance. We here discuss how fetal brain development and offspring's cognitive functions later in life is modulated in the turnstile of prenatal challenges by introducing novel and recently emerging pathway, involving maternal hormones and immune markers.

The present study sought to inquire into the subjective experience of 156 preschoolers (age 4–6.9 years) living in an area of political violence in Israel (on the border with the Gaza Strip) during a period of massive bombing. Children were invited to draw a Person Picking an Apple from a Tree (PPAT), and were interviewed on their sense of self-potency using the CAMP, a measure of potency. Teachers were asked to report problems in executive functions using a few BRIEF scales; and mothers filled out a questionnaire for maternal distress (BSI), a measure of their child strengths and difficulties (SDQ), and were asked to provide their assessment regarding the extent to which their child was exposed to political violence. Findings reveal associations between mothers' distress, the degree of exposure of their child to trauma, and the child's emotional symptoms. PPAT analysis identified four main factors: Tree Generosity, Person Agency, Vividness, and As-Real-R. Positive associations were found between self-potency and the main factors of the drawings; negative associations were found between the child's difficulties in executive functions and the drawing's four main factors; and two small negative associations were found between the child's emotional symptoms and Tree Generosity and As-Real-R factors. The following associations were found within each gender group: mothers' depression degree was associated with boy's Tree Generosity, and mother's perceptions of their girl's exposure to trauma was related to Person Agency, Tree Generosity, and As-Real-R factors; furthermore, a significant difference was found between the narrative focus of drawings in this sample and the narrative focus of drawings of a sample of the same age group from a non-war zone. In addition, narrative focus was found to be related to children's self-potency. The discussion deals with the study's findings through the prism of developmental psychology, self-agency, object-relations, and art-therapy theories. [ABSTRACT FROM AUTHOR]

(1) Background: For decades, the temperaments of infants and small children have been a focus of studies in human development and been seen as a potential contributor to children's developmental patterns. However, less is known about the interplay between the temperamental characteristics of mothers and their children in the context of explaining variations in developmental outcomes. The aim of our study was to explore the associations—with or without genetic links—of the temperaments and psychological distress of mothers and the temperaments of children with behavioral problems in a group of internationally adopted children and their adoptive mothers and in a group of non-adopted children and their mothers. (2) Methods: Data (n = 170) were derived from the ongoing Finnish Adoption (FinAdo) follow-up study. The children included were under the age of 7 years; 74 were adopted internationally through legal agencies between October 2010 and December 2016, and the remaining 96 were non-adopted children living with their birth parents (biological group) recruited from day-care centers. We used Mary Rothbart's temperament questionnaires to assess temperament, the Child Behavior Checklist (CBCL) to obtain data on the children's behavioral/emotional problems and competencies, and the General Health Questionnaire (GHQ) to assess parental psychological distress. The study was approved by the Ethics Committee of the Hospital District of Southwest Finland, and written informed consent was obtained from the parents and the children themselves. (3) Results: The negative affectivities of both mothers and children were associated with the total CBCL and with both internalizing and externalizing problem behaviors after adjusting for age, gender, and adoption status. Both relationships remained significant when tested simultaneously, suggesting additive effects. Maternal negative affect was associated with problem behavior irrespective of child extraversion/surgency. Child extraversion/surgency was associated with lower levels of all internalizing behavioral problems when adjusted for maternal sociability. Child negative affect was associated with all behavioral problem measures irrespective of maternal sociability or maternal psychological distress. Maternal distress was associated with child problem behaviors only in children with low extraversion/surgency. (4) Limitations: The sample size was relatively small, and the information was gathered solely with questionnaires. (5) Conclusions: The results of the study may be clinically significant. Child negative affect, maternal negative affect, and maternal experienced distress, combined with low child extraversion/surgency, may increase the risk of child problem behaviors in both adoptees and non-adoptees.

Abstract Background There is sufficient meta-analytic evidence that antenatal interventions for women at risk (selective prevention) or for women with severe psychological symptoms (indicated prevention) are effective in reducing postpartum distress. However, women without risk or severe psychological symptoms might also experience distress. This meta-analysis focused on the effectiveness of preventive psychological interventions offered to universal populations of pregnant women on symptoms of depression, anxiety, and general stress. Paternal and infant outcomes were also included. Method We included 12 universal prevention studies in the meta-analysis, incorporating a total of 2559 pregnant women. Results Overall, ten studies included depression as an outcome measure, five studies included stress, and four studies anxiety. There was a moderate effect of preventive interventions implemented during pregnancy on the combined measure of maternal distress (d = .52), on depressive symptoms (d = .50), and on stress (d = .52). The effect on anxiety (d = .30) was smaller. The effects were not associated with intervention timing, intervention type, intervention delivery mode, timing of post-test, and methodological quality. The number of studies including partner and/or infant outcomes was too low to assess their effectiveness. Conclusions This meta-analysis suggests that universal prevention during pregnancy is effective on decreasing symptoms of maternal distress compared to routine care, at least with regard to depression. While promising, the results with regard to anxiety and stress are based on a considerably lower number of studies, and should thus be interpreted with caution. More research is needed on preventing other types of maternal distress beyond depression. Furthermore, there is a lack of research with regard to paternal distress. Also, given the large variety in interventions, more research is needed on which elements of universal prevention work. Finally, as maternal distress symptoms can affect infant development, it is important to investigate whether the positive effects of the preventive interventions extend from mother to infant.

BackgroundIncreasing evidence suggests that maternal distress is a risk factor for development of respiratory infections and allergic diseases in the offspring. We aim to evaluate the link between maternal distress during critical periods in early life, namely the preconception, pregnancy and postnatal periods, and development of respiratory infections and allergic diseases in the offspring from the Singapore PREconception Study of long Term maternal and child Outcomes (S-PRESTO) cohort.MethodsMaternal perceived distress was evaluated using validated questionnaires including Beck Depression Inventory-II (BDI-II) administered during three time periods: preconception (three months apart at four timepoints), pregnancy (during each trimester) and postnatal (3 and 6 months post-delivery). Child eczema, rhinitis and wheeze outcomes were evaluated using a modified ISAAC questionnaire at ages 3, 6, 12, and 18 months. Child allergic sensitization was determined by skin prick testing at 18 months.ResultsAmong 332 mother-child pairs studied, higher maternal distress during preconception and pregnancy increased the risks of wheeze development in the first 18 months; for example, preconception and pregnancy BDI-II scores ≥20 were associated with increased risks of wheeze by 18 months [adjusted risk ratios 3.2 (95%CI 1.1–9.4) and 2.5 (1.0–5.9), respectively]. Emotional and practical support from family during preconception decreased the risks of offspring wheeze. No associations were observed between maternal distress and offspring eczema, rhinitis and allergic sensitization.ConclusionMaternal distress during critical early life periods was associated with offspring wheeze in the first 18 months of life. Supporting maternal mental health even before pregnancy could reduce the risk of offspring wheeze.

Background: Psychiatric disorders are associated with poor pregnancy outcomes both for mother and child. This study aimed to determine the prevalence and related demographic risk factors of psychiatric symptoms among the pregnant women in Babol City. Methods: This cross-sectional study was conducted in five private and public obstetrics clinics of Babol city. During routine appointments of prenatal care, 176 pregnant women filled in three questionnaires including; sociodemographic questionnaire, Edinburg Prenatal Depression Scale (EPDS), and Symptom Checklist-25 (SCL-25). Wilcoxon test, Spearman correlation, and multivariate logistic regression tests were used to interpret the data. Results: The prevalence of depressive disorders was 15.4%% for Edinburg scores ≥13. The overall rate of maternal psychiatric symptoms (global severity index or GSI scores ≥ 1.75) was 48.5%. The prevalence of psychiatric symptoms was high; for 25% somatization, 258% anxiety, obsession-compulsion disorders or OCD 6.4%, 8.8% interpersonal sensitivity, 5.3% phobia, 7.6% paranoid ideation, and 1.2% psychoticism. Multivariate logistic regression revealed that pregnant women with history of abortion in previous pregnancy were at risk of depressive symptoms more (β=3.18, CI 1.28-7.93, p=0.01) than those without history of abortion. Also, the only demographic factor related to psychiatric symptoms was the age of pregnant women; younger age was associated with higher symptom levels for GSI ((r=-0.17). Conclusion: The high prevalence of psychiatric symptoms, especially depressive symptoms, in pregnant women highlights the need for continued research on screening, identifying the risk factors, and developing effective treatments for mental disorders in pregnant women.

This thematic issue consists of 14 articles derived from studies of the BRISA birth cohort (Ribeirão Preto, State of São Paulo and São Luís, State of Maranhão, northeastern Brazil, a socially and economically less developed region). In these more than 40 years of existence, these cohorts have been able to document the increase in women's education, the improvement of health conditions, the creation of a public Unified Health System (SUS) that provides universal and free access to health care, eradication of hunger, and transition of the nutritional status characterized by a decrease in malnutrition rates and an increase in obesity in Brazil. Particularly in reproductive health, the country experienced a significant drop in fertility, a decrease in maternal and child mortality, and an increase in breastfeeding rates. Universal access to prenatal care and hospital delivery was accompanied by an excessive number of cesareans without clinical indication and early-term births and premature births, largely due to scheduled cesareans. Articles with a longitudinal and transversal methodological approach are presented, using structural equation analysis and propensity score, together with multivariate regressions, which gave a robust analytical treatment to articles in this thematic issue.

Pre-natal exposure to acute maternal trauma or chronic maternal distress can confer increased risk for psychiatric disorders in later life. Acute maternal trauma is the result of unforeseen environmental or personal catastrophes, while chronic maternal distress is associated with anxiety or depression. Animal studies investigating the effects of pre-natal stress have largely used brief stress exposures during pregnancy to identify critical periods of fetal vulnerability, a paradigm which holds face validity to acute maternal trauma in humans. While understanding these effects is undoubtably important, the literature suggests maternal stress in humans is typically chronic and persistent from pre-conception through gestation. In this review, we provide evidence to this effect and suggest a realignment of current animal models to recapitulate this chronicity. We also consider candidate mediators, moderators and mechanisms of maternal distress, and suggest a wider breadth of research is needed, along with the incorporation of advanced -omics technologies, in order to understand the neurodevelopmental etiology of psychiatric risk.

Background: In many countries, there is limited consideration of the psychological wellbeing of women during antenatal and postnatal care. Among a range of contributing factors, one practical reason is that brief, valid and reliable screening tools are not widely used to guide clinical interviews. The present study evaluated psychometric properties of three brief scales that measure recent wellbeing (the WHO-5 index), perceived stress (the PSS-10) and depression (the PHQ-9). Methods: A prospective birth cohort study was completed in Hue City, central Vietnam with 148 pregnant women in the third trimester of pregnancy, with follow-up 3–5 months after childbirth. Moderate-to-severe antenatal depressive symptoms were used as the reference standard to validate the WHO-5 and PSS-10. Results: Approximately one-third of the women indicated significant stress and 12% reported moderate to severe depressive symptoms during pregnancy. The WHO-5 and PSS had good internal consistency (Cronbach's alpha=0.76–0.81) and good discriminant properties against prenatal depression. Area Under the Curve (AUC) values showed good predictive validity to detect postpartum depressive symptoms for the WHO-5 [AUC=0.73, 95% CI (0.60 – 0.86)] and the PSS-10 [AUC=0.69, 95% CI (0.45 – 0.92)]. WHO-5 scores ≤ 60/100 and PSS-10 scores ≥ 20/40 provided good sensitivity (approx.83%) and fair specificity (approx.61%) to detect depression pre- and post-natally. Conclusions: Given these satisfactory psychometric properties, brief but broad screening that includes questions about positive wellbeing and recent stress in addition to depressive symptoms should be integrated into routine psychosocial care for pregnant women in Vietnam and similar cultural contexts.

Background: Maternal history of trauma is a risk factor for distress during pregnancy. The purpose of this paper was to examine the theorized differential impact of a cognitive behavioral intervention (Mothers and Babies Personalized; MB-P) on maternal distress and emotional regulation for those with ≥ 1 adverse childhood experiences (ACEs; vs no ACEs) from pregnancy to 3 months postpartum., Methods: Between August 2019 and August 2021, eligible pregnant individuals aged ≥ 18 years, < 22 weeks' gestation, and English-speaking were recruited from 6 university-affiliated prenatal clinics. Participants (N = 100) were randomized to MB-P (n = 49) or control (n = 51). Analyzable data were collected for 95 participants. Analyses tested progression of change (slope) and at individual timepoints (panel analysis) for perinatal mental health outcomes., Results: The majority of participants (n = 68, 71%) reported experiencing > 1 ACE (median = 1, range: 0-11). Participants demonstrated significant differential effects for depressive symptoms in absence of ACEs (standardized mean differences [SMD] = 0.82; 95% confidence interval [CI] = [0.13-1.51]) vs in presence of ACEs (SMD = 0.39; 95% CI = [-0.20 to 0.97]) and perceived stress in absence of ACEs (SMD = 0.92; 95% CI = [0.23-1.62]) vs in presence of ACEs (SMD = -0.05; 95% CI = [-0.63 to 0.53]). A panel analysis showed significantly reduced depressive symptoms postintervention and increased negative mood regulation at 3 months postpartum for individuals with ACEs., Conclusions: Findings support effectiveness of the MB-P intervention to reduce prenatal distress for all pregnant individuals. Preliminary exploration suggests the possibility that individuals with ACEs may benefit from enhanced trauma-informed content to optimize the effects of a perinatal intervention., Competing Interests: Conflict of InterestNone declared

Screening for postpartum mental health has a crucial role in identifying women needing psychological support. The present study aims to evaluate the psychometric properties of the Postpartum Distress Measure (PDM) in Italian women in the first six months postpartum (n = 818). The PDM is a 10-item self-report questionnaire composed of two subscales assessing general distress and obsessivecompulsive symptoms. CFA supported the two-dimensional structure of the PDM, showing good fit indices as well as high internal consistency. Furthermore, ROC analysis revealed high sensitivity and specificity of the PDM in detecting possible cases of postnatal distress with an optimal cutoff of 9. Given its good psychometric properties and its sensitivity, the PDM may be confidently used as a screening tool for maternal distress in the first six months postpartum, covering a wide range of typical perinatal psychological symptoms.

Abstract Background Effects of depression on parenting and on cognitive development of newborns are augmented when symptoms continue throughout the first postnatal year. Current classification systems recognize maternal depression as postnatal if symptoms commence within four to six weeks. Traditional cultural rituals in Sudan offer new mothers adequate family support in the first 6–8 weeks postpartum. The course of postnatal depression symptoms beyond that period is not explored in such settings. We therefore aim to investigate the change in screening status and in severity of depression and distress symptoms between three and eight months postpartum among a sample of Sudanese women using the Edinburgh Postnatal Depression Scale (EPDS) and a locally used tool: the 10-items Hopkins Symptoms Checklist (HSCL-10). Methods Three hundred pregnant women in their 2nd or 3rd trimester were recruited from two clinics in Khartoum state. They were followed up and screened for depression symptoms eight months after delivery by EPDS at ≥12, and by HSCL-10 at ≥1.85. The same sample was previously screened for depression at three months after birth. Results Prevalence of postnatal depression symptoms by EPDS was lower at eight months compared to three months after birth (3.6% at eight months (8/223) compared to 9.2% at three months (22/238), p

Background: Psychiatric disorders are associated with poor pregnancy outcomes both for mother and child. This study aimed to determine the prevalence and related demographic risk factors of psychiatric symptoms among the pregnant women in Babol City. Methods: This cross-sectional study was conducted in five private and public obstetrics clinics of Babol city. During routine appointments of prenatal care, 176 pregnant women filled in three questionnaires including; sociodemographic questionnaire, Edinburg Prenatal Depression Scale (EPDS), and Symptom Checklist-25 (SCL-25). Wilcoxon test, Spearman correlation, and multivariate logistic regression tests were used to interpret the data. Results: The prevalence of depressive disorders was 15.4%% for Edinburg scores ≥13. The overall rate of maternal psychiatric symptoms (global severity index or GSI scores ≥ 1.75) was 48.5%. The prevalence of psychiatric symptoms was high; for 25% somatization, 258% anxiety, obsession-compulsion disorders or OCD 6.4%, 8.8% interpersonal sensitivity, 5.3% phobia, 7.6% paranoid ideation, and 1.2% psychoticism. Multivariate logistic regression revealed that pregnant women with history of abortion in previous pregnancy were at risk of depressive symptoms more (β=3.18, CI 1.28-7.93, p=0.01) than those without history of abortion. Also, the only demographic factor related to psychiatric symptoms was the age of pregnant women; younger age was associated with higher symptom levels for GSI ((r=-0.17). Conclusion: The high prevalence of psychiatric symptoms, especially depressive symptoms, in pregnant women highlights the need for continued research on screening, identifying the risk factors, and developing effective treatments for mental disorders in pregnant women.

Abstract Background Maternal exposure to adversity during the perinatal period has been associated with increased susceptibility for psychiatric symptoms in the offspring. The aim of this study was to investigate a possible developmental effect of maternal perinatal stressors on emotional and behavioural symptoms in the offspring in a developing country. Methods We followed an Ethiopian birth cohort (N = 358), assessing intimate partner violence (IPV) and maternal psychiatric symptoms during the perinatal period and at follow-up 10 years later, as a proxy for adversity, and maternal ratings on the Child Behavior Checklist (CBCL) 10 years later as the outcome. Results Among the women, exposure to IPV was common (60.6%) during the perinatal period and predicted IPV (29.9% of the mothers) at follow-up (ρ = 0.132; p = 0.012). There was also an association between maternal psychiatric symptoms at the two time points (ρ = 0.136; p = 0.010) and between maternal symptoms and IPV. Current maternal symptoms of anxiety and depression (β = 0.057; p

Maternal prenatal distress (PD), frequently defined as in utero prenatal stress exposure (PSE) to the developing fetus, influences the developing brain and numerous associations between PSE and brain structure have been described both in neonates and in older children. Previous studies addressing PSE-linked alterations in neonates' brain activity have focused on connectivity analyses from predefined seed regions, but the effects of PSE at the level of distributed functional networks remains unclear. In this study, we investigated the impact of prenatal distress on the spatial and temporal properties of functional networks detected in functional MRI data from 20 naturally sleeping, term-born (age 25.85 ± 7.72 days, 11 males), healthy neonates. First, we performed group level independent component analysis (GICA) to evaluate an association between PD and the identified functional networks. Second, we searched for an association with PD at the level of the stability of functional networks over time using leading eigenvector dynamics analysis (LEiDA). No statistically significant associations were detected at the spatial level for the GICA-derived networks. However, at the dynamic level, LEiDA revealed that maternal PD negatively associated with the stability of a frontoparietal network. These results imply that maternal PD may influence the stability of frontoparietal connections in neonatal brain network dynamics and adds to the cumulating evidence that frontal areas are especially sensitive to PSE. We advocate for early preventive intervention strategies regarding pregnant mothers. Nevertheless, future research venues are required to assess optimal intervention timing and methods for maximum benefit.

New mothers actively adapt to new demands and challenges in the mothering role but some may find this adjustment difficult and distressing, depending on their perceptions and resources. Previous research on maternal distress is primarily concentrated on needs of mothers with depression but nonpathological approaches of viewing difficulties in early parenting should be explored. A secondary analysis of a descriptive, qualitative study was completed on new, low-income mothers in early parenthood to determine how maternal distress influences mothers' transition to becoming a mother and to validate the use of the Maternal Distress Concept in the clinical setting. Findings reveal new mothers experience maternal distress on various levels: stress, adaptation, functioning, and connecting. Implications for practice and education are discussed.

Milestones of brain development in mammals are completed before birth, which provide the prerequisite for cognitive and intellectual performances of the offspring. Prenatal challenges, such as maternal stress experience or infections, have been linked to impaired cognitive development, poor intellectual performances as well as neurodevelopmental and psychiatric disorders in the offspring later in life. Fetal microglial cells may be the target of such challenges and could be functionally modified by maternal markers. Maternal markers can cross the placenta and reach the fetus, a phenomenon commonly referred to as “vertical transfer.” These maternal markers include hormones, such as glucocorticoids, and also maternal immune cells and cytokines, all of which can be altered in response to prenatal challenges. Whilst it is difficult to discriminate between the maternal or fetal origin of glucocorticoids and cytokines in the offspring, immune cells of maternal origin—although low in frequency—can be clearly set apart from offspring's cells in the fetal and adult brain. To date, insights into the functional role of these cells are limited, but it is emergingly recognized that these maternal microchimeric cells may affect fetal brain development, as well as post-natal cognitive performances and behavior. Moreover, the inheritance of vertically transferred cells across generations has been proposed, yielding to the presence of a microchiome in individuals. Hence, it will be one of the scientific challenges in the field of neuroimmunology to identify the functional role of maternal microchimeric cells as well as the brain microchiome. Maternal microchimeric cells, along with hormones and cytokines, may induce epigenetic changes in the fetal brain. Recent data underpin that brain development in response to prenatal stress challenges can be altered across several generations, independent of a genetic predisposition, supporting an epigenetic inheritance. We here discuss how fetal brain development and offspring's cognitive functions later in life is modulated in the turnstile of prenatal challenges by introducing novel and recently emerging pathway, involving maternal hormones and immune markers.
