Maternal-fetal attachment, parenting stress during infancy, and child outcomes at age 3Â years
Maternal-fetal attachment (MFA), a woman's relationship with and affiliative behaviors toward her unborn child, has been linked to near-term infant physical and developmental outcomes. However, further longitudinal research is needed to understand whether the impact of MFA extends past the earliest years of life. The current study explored relationships between MFA and child socioemotional competence and behavior problems at age 3 and whether parenting stress mediated the association between MFA and child outcomes. Data were collected from 221 primarily Black/African-American mothers who completed a scale of MFA during pregnancy. Mothers reported on parenting stress at infant age 7 months and reported on child socioemotional competence and problem behaviors at child age 3 years. In path analyses, MFA was directly associated with child socioemotional competence at age 3 years, but an indirect association between MFA and socioemotional competence via parenting stress was not significant. We also observed a significant indirect association between lower MFA and child internalizing behavior problems via parenting stress that was related to maternal dissatisfaction regarding interactions with her child. Findings suggest that assessing MFA may serve as a means to identify dyads who would benefit from support to promote individual health outcomes.

COVID-19 and Youth Who Have Experienced Commercial Sexual Exploitation: A Role for Child Mental Health Professionals During and in the Aftermath of a Pandemic [Editorial]
The COVID-19 pandemic has exacerbated some of the most pressing social problems and structural inequities, with a disproportionate impact on some of the most vulnerable youth. The goal of this article is to raise awareness among child mental health professionals of the ways in which the pandemic has likely exacerbated the commercial sexual exploitation of children in the United States. A second goal is to promote child mental health professionals' ability to identify and care for these resilient yet underresourced youth.

Short Research Article: Impact of a prolonged lockdown on the symptoms of paediatric ADHD and common associated disorders
OBJECTIVE:Our objective is to explore the change in the severity of ADHD, ODD and anxiety during a two-month lockdown among children in France and the moderating role of behavioural regulation. METHOD:In 235 children with ADHD, the symptom severity of ADHD, ODD and anxiety was investigated one and two months after the beginning of lockdown, and one month after its end. Behavioural regulation skills were estimated with the Behaviour Regulation Index. RESULTS:ADHD, ODD and anxiety scores were increasing or decreasing depending on BRI. CONCLUSION:Baseline behavioural regulation skills may act as a moderating factor for the persistence of ADHD, ODD and anxiety symptoms related to the lockdown.

Intestinal Predictors of Whole Blood Serotonin Levels in Children With or Without Autism
Hyperserotonemia, or elevated levels of whole blood serotonin (WB5-HT), was the first biomarker linked to autism spectrum disorder (ASD). Despite numerous studies investigating the etiology of hyperserotonemia, results have been inconsistent. Recent findings suggest a relationship between the immune system and hyperserotonemia. The current study investigated whether intestinal 5-HT levels, 5-HT gene expression, or intestinal cell types predict WB5-HT. Participants included thirty-one males aged 3-18 who were classified into one of three groups: ASD and functional GI issues, typically developing with GI issues, and typically developing without GI issues. Samples from a lower endoscopy were analyzed to examine the pathways in predicting WB-5HT. Results demonstrated an association between T-Lymphocytes and WB5-HT.

Structural Brain Correlates of Childhood Inhibited Temperament: An ENIGMA-Anxiety Mega-analysis
Temperament involves stable behavioral and emotional tendencies that differ between individuals, which can be first observed in infancy or early childhood and relate to behavior in many contexts and over many years.1 One of the most rigorously characterized temperament classifications relates to the tendency of individuals to avoid the unfamiliar and to withdraw from unfamiliar people, objects, and unexpected events. This temperament is referred to as behavioral inhibition or inhibited temperament (IT).2 IT is a moderately heritable trait1 that can be measured in multiple species.3 In humans, levels of IT can be quantified from the first year of life through direct behavioral observations or reports by caregivers or teachers. Similar approaches as well as self-report questionnaires on current and/or retrospective levels of IT1 can be used later in life.

Family-level correlates of disruptive behavior challenges among children in Southwestern Uganda
Introduction: This exploratory study sought to examine the extent to which family-level factors are associated with disruptive behavioral disorder (DBD) symptoms, including oppositional defiant disorder (ODD) and conduct disorder (CD) among school children in Uganda, a low-resource country in SSA. The examination of key influences within the SSA context is important to guide needed investments in mental health care and family-level support. Importantly, identifying families at higher risk can inform the development of contextualized family interventions that reinforce positive parenting practices. Method: We analyzed baseline data (N = 2110) from the NIH-funded Strengthening Mental health And Research Training in Africa (SMART Africa) scale-up study in Southwestern Uganda. Children aged 8-13 and their caregivers were recruited from 30 public primary schools. DBDs were examined using the DBD rating scale, Iowa Conners, and Impairment scales. Logistic regression analysis using cluster adjusted robust standard errors to adjust for within-school clustering was conducted to assess the association between DBD symptoms and family-level factors, including parenting practices, marital status, and family size. Results: Results indicate that poor parental supervision (OR = 1.17; CI: 1.13, 1.21; P < .001), divorced families (OR = 1.33; CI: 1.03, 1.72; P < .05), and widowed families (OR = 1.48; CI: 1.10, 2.00; P < .01) were associated with higher DBD symptoms among children. On the other hand, caregiver age (OR = 0.99; CI: 0.98, 0.99; P < .01) was associated with lower DBD symptoms among children. Moreover, caregiver employment and parental education were not statistically significant in the model. Conclusion: Findings from the study reveal an association between family-level factors and behavioral difficulties among children in Uganda suggesting that divorced and widowedfamilies may benefit from additional support in caring for children. Moreover, caregivers may also benefit from programs that provide tools for effective parental supervision. (PsycInfo Database Record (c) 2022 APA, all rights reserved)

Pregnant women with bipolar disorder who have a history of childhood maltreatment: Intergenerational effects of trauma on fetal neurodevelopment and birth outcomes
OBJECTIVES/OBJECTIVE:Intergenerational transmission of trauma occurs when the effects of childhood maltreatment (CM) influence the next generation's development and health; prenatal programming via maternal mood symptoms is a potential pathway. CM is a risk factor for bipolar disorder which is present in 1.8% of pregnant women. Mood symptoms are likely to increase during pregnancy, particularly for those with a history of CM. We examined whether there was evidence for intergenerational transmission of trauma in utero in this population, and whether maternal mood was a transmission pathway. METHODS:CM and maternal mood were self-reported by N = 82 pregnant women in treatment for bipolar disorder. Fetal heart rate variability (FHRV) was measured at 24, 30, and 36 weeks' gestation. Gestational age at birth and birth weight were obtained from medical charts. RESULTS:A cluster analysis yielded two groups, Symptom+ (18.29%) and Euthymic (81.71%), who differed on severe mood symptoms (p < 0.001) but not on medication use. The Symptom+ group had more CM exposures (p < 0.001), a trend of lower FHRV (p = 0.077), and greater birth complications (33.3% vs. 6.07% born preterm p < 0.01). Maternal prenatal mood mediated the association between maternal CM and birth weight in both sexes and at trend level for gestational age at birth in females. CONCLUSIONS:This is the first study to identify intergenerational effects of maternal CM prior to postnatal influences in a sample of pregnant women with bipolar disorder. These findings underscore the potential enduring impact of CM for women with severe psychiatric illness and their children.

Effects of Short Chain Fatty Acid Supplementation in Modulation of Gut Microbiome and T-Regulatory Cells in Health and New Onset Rheumatoid Arthritis [Meeting Abstract]
Background/Purpose: The gut microbiome and its metabolites are dysregulated in rheumatoid arthritis. Short chain fatty acids (SCFAs), microbial fermentation byproducts of certain gut microbes, induce regulatory T cells (Treg) that exhibit antiinflammatory properties. Unsurprisingly, SCFA are found at reduced levels in both murine models of RA and patients. The SCFA butyrate has been shown to increase levels of gut and circulating Treg and ameliorate inflammatory arthritis in murine models. Additionally, we previously noted that SCFA supplementation in WT mice led to significant perturbations in gut bacterial composition with a significant increase in SCFA-producing commensals. Similarly, others have shown that a high-fiber diet increases circulating levels of SCFAs and decreases pro-arthritogenic cytokines (Durholz et al. Nutrients. 2020). We therefore hypothesized that butyrate supplementation may promote favorable gut microbial changes and increase tolerogenic adaptive immune response in RA patients.
Method(s): We designed an ongoing, prospective, proof-of-principle study to determine the effects of butyrate supplementation in new-onset RA (NORA) patients. First, we evaluated the effects of butyrate supplementation in healthy subjects (n=7; 1 gm 3 times daily for 14 days). Next, we evaluated the effects of butyrate on new-onset RA (n=5; 1 gm 3 times daily for 30 days) compared to methotrexate (n=20). Clinical history and joint exam were performed at baseline and follow up. Peripheral blood and fecal samples were collected at baseline and follow up for flow cytometric analysis of Treg and 16s rRNA sequencing, respectively. Wilcoxon signed-rank test was used to compare differences in Treg before and after butyrate administration.
Result(s): Although butyrate supplementation in healthy subjects did not lead to significant community changes by 7 days, it did lead to a significant increase in the percentage of circulating CD4+CD25+FoxP3+ Treg (p=0.02) followed by a significant increase in highly activated CD39+ Treg by 14 days (p < 0.0001). Gut bacterial alpha diversity (Shannon index) was significantly lower in NORA patients compared to healthy subjects at baseline (p=0.04; wilcox-test). After butyrate supplementation, NORA alpha diversity increased to levels approaching those of healthy subjects, with a modest increase in abundance of both Firmicutes and Bacteroidetes. LDA Effect Size analysis recapitulated previous studies where healthy subjects had greater abundance of SCFA producing commensals compared to NORA.
Conclusion(s): In both health and new-onset RA, butyrate supplementation is associated with changes in human gut microbiota composition and in peripheral Treg abundance and markers of Treg activation. In preliminary analyses of this ongoing prospective study, butyrate increased gut microbial diversity in NORA, suggesting that gut microbial composition may shift towards a healthier level of diversity. As seen in murine models, butyrate also increased Treg in healthy subjects. We hypothesize that, in patients, butyrate will induce modifications in gut microbial communities that favor a regulatory adaptive immune response that may ultimately lead to better clinical response

Reprint of: Advanced paternal age and risk of schizophrenia in offspring - Review of epidemiological findings and potential mechanisms
A large number of studies have examined the association between advanced paternal age (APA) and risk of schizophrenia in offspring. Here we present an overview of epidemiological studies on this subject published since 2000, and systematically summarize their methodologies and results. Next, we discuss evidence to elucidate the potential mechanisms contributing to the association between APA and offspring schizophrenia, considering paternal psychiatric morbidity and genetic liability, maternal factors, and findings from family design studies. We propose that multiple mechanisms, including causal and non-causal pathways, contribute to the observed relationship between APA and schizophrenia in offspring, and conclude by highlighting the need for multi-disciplinary studies in disentangling these complex, non-mutually exclusive mechanisms.
