Review
Two neurodevelopmental conditions, autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), have been associated with executive function (EF) impairments but the specificity of their impairments is still controversial. The present meta-analysis aimed to identify the differences in EF profiles of ASD, ADHD, and ASD+ADHD in relation to a control group of individuals with typical development (TD) and to understand whether the EF performance could change depending upon the type of measure used to assess EF (performance tests vs. questionnaires). Results from 36 eligible studies revealed that ADHD and ASD showed more difficulties than the TD group in tests and, particularly, in questionnaires. No significant differences in the EF profile emerged between ASD and ADHD when assessed through neuropsychological tests ( = 0.02), while significant differences emerged when assessed through questionnaires, with ADHD having higher ratings than ASD ( = -0.34). EF questionnaires and neuropsychological tests may catch two different constructs of EF, with the former being more predictive of everyday life EF impairments. The comparison between the double diagnosis group (ADHD+ASD) and the clinical groups pointed out that the former has a more similar EF profile to the ADHD-alone one and that it shows more difficulties than ASD-alone.

The present study was conducted to investigate the differences in cadmium (Cd) and mercury (Hg) concentrations between children with autism spectrum disorder (ASD) and controls. In this systematic review and meta-analysis study, three thousand one hundred forty-five studies were collected from scientific databases including Web of Science, Scopus, PubMed, and Google Scholar from January 2000 to October 2022 and were investigated for eligibility. As a result, 37 studies published in the period from 2003 to 2022 met our inclusion criteria and were considered in the meta-analysis. The heterogeneity assumption was evaluated using the Chi-squared-based Q-test and I-squared (I) statistics. The pooled estimates were shown in the forest plots with Hedges' g (95% confidence interval) values. The random effects model demonstrated that there is no significant difference in the blood (Hedges' g: 0.14, 95% CI: 0.45, 0.72, > 0.05), hair (Hedges' g: 0.12, 95% CI: 0.26, 0.50, > 0.05), and urinary (Hedges' g: 0.05, 95% CI: 0.86, 0.76, > 0.05) Cd levels of the case group versus control subjects. Moreover, the pooled findings of studies showed no significant difference in the blood (Hedges' g: 1.69, 95% CI: 0.09, 3.48, > 0.05), hair (Hedges' g: 3.42, 95% CI: 1.96, 8.80, > 0.05), and urinary (Hedges' g: 0.49, 95% CI: 1.29 - 0.30, > 0.05) Hg concentrations. The results demonstrated no significant differences in Hg and Cd concentrations in different biological samples of children with ASD compared to control subjects.

Review
Serious games represent a promising avenue for intervention with children diagnosed with autism spectrum disorder, a neurodevelopmental disorder marked by persistent challenges in social communication and the presence of restricted, repetitive behaviors. Despite this potential, comprehensive reviews on this subject are scarce. This systematic review aims to evaluate the effectiveness of serious games and their specific characteristics in enhancing social skills among children and adolescents with autism. Employing PICO strategies and adhering to PRISMA guidelines, we screened 149 studies initially identified through PubMed and EBSCOhost databases. Nine studies met inclusion criteria and found a positive influence of serious games on social skills and related domains, encompassing emotion recognition/encoding/decoding, emotional regulation, eye gaze, joint attention, and behavioral skills. Nevertheless, despite these promising results, the limited available evidence underscores the need for rigorous study designs to consolidate findings and integrate evidence-based intervention strategies.

INTRODUCTION
Autism Spectrum Disorder is a complex neurodevelopmental syndrome that profoundly affects social interactions, communication, and sensory perception. The research traced the evolution of autism research from 2011-2022, specifically focusing on the screening and diagnosis of children and students.
METHODS
Through an analysis of 12,262 publications using the PRISMA framework, bibliographic coupling, science mapping, and citation analysis, this study illuminates the growth trajectory of ASD research and significant disparities in diagnosis and services.
RESULTS
The study indicates an increasing trend in autism research, with a strong representation of female authorship. Open Access journals show a higher average citation impact compared to their closed counterparts. A keyword co-occurrence analysis revealed four central research themes: Child Development and Support Systems, Early Identification and Intervention, Prevalence and Etiology, and Mental Health. The pandemic's onset has prioritized research areas like mental health, telehealth, and service accessibility.
DISCUSSION
Recommendations on a global level stress the importance of developing timely biological markers for ASD, amplifying Disability Inclusion research, and personalizing mental health services to bridge these critical service gaps. These strategies, underpinned by interdisciplinary collaboration and telehealth innovation, particularly in low-resource settings, can offer a roadmap for inclusive, context-sensitive interventions at local levels that directly support SDG3's aim for health and well-being for all.

BACKGROUND
Children with autism spectrum disorders are frequent visitors to high technology environments, and their needs may differ from those of their typically developed peers. Procedures in high technology environments can constitute a challenge for these children and their parents since the environment presents many challenges relevant to the child's impairments. This systematic review aimed to explore the experiences of children with autism spectrum disorders and their parents during procedures in a high technology environment.
METHODS
The following sources were searched for this systematic review: Cochrane CENTRAL Trials, CINAHL, Dentistry and Oral Sciences Source, MEDLINE, PsycINFO, Scopus, and Web of Science Core Collection. The search terms included variants of the following concepts: (1) children with autism spectrum disorder and/or their parents and (2) anesthesia or radiographic departments. Publications were not limited by date or study design.
RESULT
Out of 13,389 bibliographic records, nine studies were eligible for synthesis. After another search in October 2022, one additional study was eligible for synthesis.None of the studies reported children's experiences, and all ten reported their parents' experiences. Only one study was conducted in a radiographic context. Parents' experiences were both positive and negative and were categorized into two main categories: (1) challenges in a new environment and (2) health care professionals' approaches.
CONCLUSION
Studies describing children's experiences with procedures in high technology environments are lacking. The parents described a need for health care professionals to work in structured ways with their child and to be able to make suitable adaptations.

Under the (5th ed.), language impairment can co-occur with autism. It is not yet clear how research defines, reports, and characterizes structural language abilities of autistic individuals eligible for school-based special education services (aged 3-21 years) in the United States. In the United States, students typically must be formally diagnosed to be eligible for services and supports. However, the quality of diagnosis is only as good as the research evidence on which diagnosis depends. To evaluate evidence quality, we examined how studies of school-aged autistic individuals report assessments of language ability. This systematic review included 57 studies using English language age-referenced assessments used to measure structural language. Findings showed many differences across studies in how language abilities were measured and reported. Also, none of the studies fully reported the variables relevant to characterizing language impairment. Outcomes were similar across versions of the . Findings indicate that researchers and clinicians should pay attention to reporting diagnostic and grouping criteria. Carefully interpreting research evidence is critical for ensuring that diagnostic criteria and supports are representative of and accessible to autistic individuals and relevant parties.

BACKGROUND
Given the rising interest in complementary therapeutic strategies for autism spectrum disorder (ASD), this research aims to provide a comprehensive analysis of the impact of animal-assisted activities and therapies (AAAT) on various ASD symptoms.
METHODS
A meticulous search of databases, including Scopus and PubMed, was conducted to gather relevant research on AAAT for ASD. This process led to the selection of 45 studies encompassing 1,212 participants. The chosen studies were then subjected to a meta-analysis to evaluate the efficacy of AAAT in alleviating core ASD symptoms.
RESULTS
The meta-analysis revealed significant improvements in several core ASD symptoms due to AAAT. Notably, there were improvements in social communication (MD = -4.96, 95% CI [-7.49, -2.44]), irritability (MD = -2.38, 95% CI [-4.06, -0.71]), hyperactivity (MD = -4.03, 95% CI [-6.17, -1.89]), and different word usage skills (MD = 20.48, 95% CI [7.41, 33.55]). However, social awareness (MD = -1.63, 95% CI [-4.07, 0.81]), social cognition (MD = -3.60, 95% CI [-9.36, 2.17]), social mannerisms (MD = -0.73, 95% CI [-2.55, 1.09]), social motivation (MD = -1.21, 95% CI [-2.56, 0.13]), lethargy (MD = -1.12, 95% CI [-3.92, 1.68]), and stereotypical behaviors (MD = -0.23, 95% CI [-1.27, 0.80]) did not significantly improve.
CONCLUSION
The study demonstrates the potential of AAAT in improving certain core symptoms of ASD, such as social communication, irritability, hyperactivity, and word usage skills. However, the effectiveness of AAAT in other ASD symptom domains remains uncertain. The research is limited by the absence of long-term follow-up data and a high risk of bias in existing studies. Therefore, while the findings indicate the promise of AAAT in specific areas, caution is advised in generalizing its efficacy across all ASD symptoms.

Meta-Analysis Review
There is limited recent research on the association between parenting practices and externalizing behaviors in autistic children. To address this gap, the current systematic review examined the associations between parenting practices and externalizing behaviors in autistic children, along with the mediating and moderating effects of parent and child variables (PROSPERO registration number CRD42022268667). Study inclusion criteria were (1) Peer-reviewed journals, (2) Participants included parents of autistic children and their children, (3) Quantitative measures of both parenting practices or behaviors/style and child externalizing behaviors, (4) Cross-sectional or longitudinal studies only, and (5) Studies published in English. Study exclusion criteria were: (1) Qualitative studies, (2) Published in a language other than English, (3) Participants included non-human participants, (4) Participants that did not include parents and their autistic children as participants or did not report this group separately, (5) Systematic review and meta-analyses, and (6) No quantitative measures of parenting practices and/or child externalizing behaviors. Quality appraisal and risk of bias were conducted using the McMaster Tool and results were synthesized in Covidence and Excel. Thirty studies were included in the review. Results demonstrated that mindful parenting was associated with fewer or lower levels of externalizing behaviors; positive parenting practices had non-significant associations with externalizing behaviors; specific parenting practices had differing associations with externalizing behaviors; and negative parenting practices were associated with higher levels of externalizing behaviors. We are unable to draw causal relationships due to focus on cross-sectional and longitudinal articles only. The potential for future research to target specific parent practices to support children's externalizing behaviors is discussed.

Review
: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social communication challenges and repetitive behaviors. Recent research has increasingly focused on the genetic underpinnings of ASD, with the Neurexin 1 () gene emerging as a key player. This comprehensive systematic review elucidates the contribution of gene variants in the pathophysiology of ASD. : The protocol for this systematic review was designed a priori and was registered in the PROSPERO database (CRD42023450418). A risk of bias analysis was conducted using the Joanna Briggs Institute (JBI) critical appraisal tool. We examined various studies that link gene disruptions with ASD, discussing both the genotypic variability and the resulting phenotypic expressions. : Within this review, there was marked heterogeneity observed in ASD genotypic and phenotypic manifestations among individuals with mutations. The presence of mutations in this population emphasizes the gene's role in synaptic function and neural connectivity. : This review not only highlights the role of in the pathophysiology of ASD but also highlights the need for further research to unravel the complex genetic underpinnings of the disorder. A better knowledge about the multifaceted role of in ASD can provide crucial insights into the neurobiological foundations of autism and pave the way for novel therapeutic strategies.

Nutrition & Diabetes May 2024Vitamin D deficiency has been linked with several adverse maternal and fetal outcomes.
BACKGROUND
Vitamin D deficiency has been linked with several adverse maternal and fetal outcomes.
OBJECTIVE
To summarize systematic reviews and meta-analyses evaluating the effects of vitamin D deficiency and of vitamin D supplementation in pregnancy on maternal and offspring health-related outcomes.
METHODS
Prior to conducting this umbrella review, we registered the protocol in PROSPERO (CRD42022368003). We conducted searches in PubMed, Embase, and Cochrane Library for systematic reviews and meta-analyses on vitamin D in pregnancy, from database inception to October 2, 2023. All outcomes related to vitamin D in pregnancy obtained from the systematic reviews and meta-analyses were extracted.
DATA EXTRACTION
Two reviewers independently chose studies and collected information on health outcomes. The quality of the included articles' methodology was assessed using AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews-2).
RESULTS
We identified 16 eligible systematic reviews and meta-analyses, which included 250,569 women. Our results demonstrated that vitamin D deficiency in pregnancy is associated with increased risk of preterm birth, small-for gestational age/low birth weight infants, recurrent miscarriage, bacterial vaginosis and gestational diabetes mellitus. Vitamin D supplementation in pregnancy increases birth weight, and reduces the risk of maternal pre-eclampsia, miscarriage, and vitamin D deficiency, fetal or neonatal mortality, as well as attention-deficit hyperactivity disorder, and autism spectrum disorder in childhood. In women with gestational diabetes mellitus, vitamin D supplementation in pregnancy can reduce the risk of maternal hyperbilirubinemia, polyhydramnios, macrosomia, fetal distress, and neonatal hospitalization.
CONCLUSION
Due to the association with adverse maternal and offspring health outcomes, we recommend the vitamin D status in pregnancy should be monitored, particularly in women at high risk of vitamin D deficiency. It is suggested that pregnant women take a dose of >400 IU/day of vitamin D supplementation during pregnancy to prevent certain adverse outcomes.
