Shared and Specific Neural Correlates of Attention Deficit Hyperactivity Disorder and Autism Spectrum Disorder: A Meta-Analysis of 243 Task-Based Functional MRI Studies.

OBJECTIVE: To investigate shared and specific neural correlates of cognitive functions in attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), the authors performed a comprehensive meta-analysis and considered a balanced set of neuropsychological tasks across the two disorders. METHODS: A broad set of electronic databases was searched up to December 4, 2022, for task-based functional MRI studies investigating differences between individuals with ADHD or ASD and typically developing control subjects. Spatial coordinates of brain loci differing significantly between case and control subjects were extracted. To avoid potential diagnosis-driven selection bias of cognitive tasks, the tasks were grouped according to the Research Domain Criteria framework, and stratified sampling was used to match cognitive component profiles. Activation likelihood estimation was used for the meta-analysis. RESULTS: After screening 20,756 potentially relevant references, a meta-analysis of 243 studies was performed, which included 3,084 participants with ADHD (676 females), 2,654 participants with ASD (292 females), and 6,795 control subjects (1,909 females). ASD and ADHD showed shared greater activations in the lingual and rectal gyri and shared lower activations in regions including the middle frontal gyrus, the parahippocampal gyrus, and the insula. By contrast, there were ASD-specific greater and lower activations in regions including the left middle temporal gyrus and the left middle frontal gyrus, respectively, and ADHD-specific greater and lower activations in the amygdala and the global pallidus, respectively. CONCLUSIONS: Although ASD and ADHD showed both shared and disorder-specific standardized neural activations, disorder-specific activations were more prominent than shared ones. Functional brain differences between ADHD and ASD are more likely to reflect diagnosis-related pathophysiology than bias from the selection of specific neuropsychological tasks.

Interventions for expectant and new parents who are at increased risk for perpetrating child abuse and neglect: protocol for a systematic review and meta-analysis.

INTRODUCTION: The prevention of child abuse and neglect is an urgent matter given the serious effects persisting into adulthood, and the increased risk of the offspring of abused children being abusive themselves. Intervening as early as possible may prevent abuse that can begin in infancy. Although several systematic reviews have investigated the effects of interventions on populations who are at increased risk for perpetrating child abuse and neglect, few studies have focused on women or interventions that start during perinatal periods. This study aims to describe a systematic review to examine the effects of interventions to prevent child abuse and neglect that begin during pregnancy and immediately after childbirth (less than 1 year). The study will involve performing a systematic review and meta-analysis based on the latest research articles and a broader literature search. METHODS AND ANALYSIS: The protocol was prepared using the 2015 statement of Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The review will follow Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The literature search will be performed using the MEDLINE, PsycINFO, Embase and Cochrane Central Register of Controlled Trials databases from inception onward. Randomised controlled trials of interventions that begin during pregnancy or the first year postpartum, designed to prevent child abuse and neglect in families who are at increased risk for these issues, will be included. Data collection, quality assessment and statistical syntheses will be conducted by following the methods in the protocol that are predefined. Any index of child maltreatment will be included as a primary outcome. A meta-analysis and sub-group analyses will be considered based on the characteristics of interventions. ETHICS AND DISSEMINATION: This study does not require ethical approval. The findings will be presented at conferences and will be submitted to a peer-reviewed journal.

Transfer of Zolpidem to Cord Blood and Breast Milk: A Case Series Evaluating Zolpidem Serum Levels and Outcomes in Birth and Suckling Infants.

Background: Zolpidem is used for insomnia in pregnant and lactating women. Although zolpidem has been shown to cross the placenta and to be secreted into breast milk, it would not be expected to cause any adverse effects in newborn and breastfed infants. However, there is no relevant information on serum zolpidem levels in the newborn and breastfed infant from zolpidem-treated mother. This study aimed to present the outcomes of zolpidem exposure into infant who was delivered or breastfed by a zolpidem-treated mother. Methods: In this case series, zolpidem-treated pregnant women were recruited between September 2019 and April 2022, and maternal serum, cord blood, breast milk, and infants' serum were collected, and the zolpidem concentration in each sample was evaluated. Childbirth outcomes, including 1-month health care checkup, were also evaluated. Results: Three cases were recruited during investigation period. No spontaneous abortion or preterm live deliveries occurred. Oxygen intervention was required in one term infant, but the findings resolved on postpartum day 1. No medical intervention was required in other three infants. Zolpidem was not detected in infants' serum even after breastfeeding. There are no abnormal developmental findings in any of the infants in their 1-month health checkups. Conclusions: Zolpidem transferred into fetal circulation in utero and breast milk, however no harmful findings existed in infants during pregnancy and lactation. Exposure doses through breastfeeding is small, which may be a cause of rare detection from the infants' serum. Due to the limited number of cases, larger studies and integrated review are needed.

Autistic children and adolescents with frequent restricted interest and repetitive behavior showed more difficulty in social cognition during mask-wearing during the COVID-19 pandemic: a multisite survey.

BACKGROUND: The public health measures enacted in order to control the coronavirus disease (COVID-19) pandemic have caused considerable changes to daily life. For autistic children and adolescents, adapting to the "new normal," including mask-wearing, may be difficult because of their restricted interest and repetitive behavior (RRB) characteristics. We aimed to examine the relationships between RRB characteristics and the impact of mask-wearing on their social communications during the pandemic. METHODS: We recruited participants with a clinical diagnosis of autism spectrum disorder based on DSM-5 diagnostic criteria from two outpatient clinics in Tokyo, Japan, between November 2020 and April 2021 using a convenience sampling methodology. As a result, the participants consisted of 102 children and adolescents (mean (SD) age = 11.6 (5.3)). We collected data on RRB characteristics frequency before and during the pandemic using the CoRonavIruS Health Impact Survey (CRISIS) - Adapted for Autism and Related Neurodevelopmental conditions (AFAR). We then conducted factor analyses to compute the RRB severity composite scores, which are divided into lower- (e.g., sensory seeking), and higher-order (e.g., restricted interest). We also investigated mask-wearing culture using a bespoke questionnaire, and using Spearman's rank correlation analyses, we examined the relationships between before pandemic RRB characteristics, and the impact of mask-wearing on social communications during the pandemic. RESULTS: We found that children and adolescents who exhibited lower-order RRB before the pandemic had difficulties in going-out with mask-wearing (rho = -0.25, q = .031), more challenges with mask-wearing (rho = - 0.34, q = .0018), and difficulty in referring to others' emotions while wearing masks (rho = - 0.36, q = .0016). We also found an association between higher-order RRB before the pandemic and an uncomfortable sensation (rho = - 0.42, q = .0002) and difficulties in referring to other's emotions while wearing masks (rho = - 0.25, q = .031). CONCLUSIONS: We revealed that various behaviors, such as sensory seeking, repetitive motor mannerisms and movements, and rituals and routines, undertaken before the pandemic could be important predictors of difficulties with mask-wearing and social communication for autistic children and adolescents during the pandemic. Caregivers and teachers wearing masks may need to provide extra support for social communication to autistic children and adolescents showing RRB characteristics frequently.
