Fragile X syndrome (FXS) is a common inherited cause of intellectual disabilities and single-gene cause of autism spectrum disorder (ASD), resulting from the loss of functional fragile X messenger ribonucleoprotein (FMRP), an RNA-binding protein (RBP) encoded by the fragile X messenger ribonucleoprotein 1 (FMR1) gene. Ribonucleic acid (RNA) methylation can lead to developmental diseases, including FXS, through various mechanisms mediated by 5-hydroxymethylcytosine, 5-methylcytosine, N(6)-methyladenosine, etc. Emerging evidence suggests that modifications of some RNA species have been linked to FXS. However, the underlying pathological mechanism has yet to be elucidated. In this review, we reviewed the implication of RNA modification in FXS and summarized its specific characteristics for facilitating the identification of new therapeutic targets.

3. Crawford H. Social Anxiety in Neurodevelopmental Disorders: The Case of Fragile X Syndrome. Am J Intellect Dev Disabil;2023 (Jul 1);128(4):302-318.
Despite significant advances in understanding and treating social anxiety in the general population, progress in this area lags behind for individuals with intellectual disability. Fragile X syndrome is the most common cause of inherited intellectual disability and is associated with an elevated prevalence rate of social anxiety. The phenotype of fragile X syndrome encompasses multiple clinically significant characteristics that are posed as risk markers for social anxiety in other populations. Here, evidence is reviewed that points to physiological hyperarousal, sensory sensitivity, emotion dysregulation, cognitive inflexibility, and intolerance of uncertainty as primary candidates for underlying mechanisms of heightened social anxiety in fragile X syndrome. A multilevel model is presented that provides a framework for future research to test associations.

4. Ding M, Shi S, Qie S, Li J, Xi X. Association between heavy metals exposure (cadmium, lead, arsenic, mercury) and child autistic disorder: a systematic review and meta-analysis. Front Pediatr;2023;11:1169733.
BACKGROUND: Studies have found that toxic heavy metals exposure could induce the generation of reactive oxygen species (ROS), and is of epigenetic effect, which might be associated with the occurrence of Autistic Disorder (ASD). This systematic review and meta-analysis aims to elucidate the association between exposure to 4 heavy metals, cadmium (Cd), lead (Pb), arsenic(As), and mercury (Hg), and the occurrence of ASD in children. METHODS: We searched PubMed, Web of Science, Embase, and Cochrane Library, from their inception to October 2022, for epidemiological investigations that explore the association between exposure to Cd, Pb, As, or Hg and the occurrence of child ASD. RESULTS: A total of 53 studies were included, involving 5,054 individuals aged less than 18 (2,533 ASD patients and 2,521 healthy controls). Compared with the healthy controls, in hair and blood tests, concentrations of the 4 heavy metals were significantly higher in the ASD group than in the healthy control group, and the differences in Pb, arsenic and Hg were statistically significant (P < 0.05). In the urine test, concentrations of arsenic and Hg were significantly higher in the ASD group than in the healthy control group (P < 0.05), while the results of Cd and Pb were opposite to those of arsenic and Hg (P > 0.05). Subgroup analysis for geographic regions showed that ASD patients in Asia and Europe had higher concentrations of the 4 heavy metals, compared with the healthy controls, in which the differences in Pb, arsenic, and Hg were statistically significant (P < 0.05), while in North America, the healthy controls had higher Cd, arsenic, and Hg concentrations (P > 0.05). CONCLUSION: Compared with the healthy control group, the ASD group had higher concentrations of Cd, Pb, arsenic, and Hg. These 4 heavy metals play different roles in the occurrence and progression of ASD. Moreover, there is significant heterogeneity among the included studies due to controversies about the study results among different countries and regions and different sources of detection materials. The results of this study firmly support the policies to limit heavy metals exposure, especially among pregnant women and young children, so as to help reduce the incidence of ASD.

Subjective and objective sleep alterations in medication-naïve children and adolescents with autism spectrum disorder: a systematic review and meta-analysis. Epidemiol Psychiatr Sci;2023 (Jul 20);32:e48.
AIMS: This study aimed to summarize the evidence on sleep alterations in medication-naïve children and adolescents with autism spectrum disorder (ASD). METHODS: We systematically searched PubMed/Medline, Embase and Web of Science databases from inception through March 22, 2021. This study was registered with PROSPERO (CRD42021243881). Any observational study was included that enrolled medication-naïve children and adolescents with ASD and compared objective (actigraphy and polysomnography) or subjective sleep parameters with typically developing (TD) counterparts. We extracted relevant data such as the study design and outcome measures. The methodological quality was assessed through the Newcastle-Ottawa Scale (NOS). A meta-analysis was carried out using the random-effects model by pooling effect sizes as Hedges’ g. To assess publication bias, Egger’s test and p-curve analysis were done. A priori planned meta-regression and subgroup analysis were also performed to identify potential moderators. RESULTS: Out of 4277 retrieved references, 16 studies were eligible with 981 ASD patients and 1220 TD individuals. The analysis of objective measures showed that medication-naïve ASD patients had significantly longer sleep latency (Hedges’ g 0.59; 95% confidence interval [95% CI] 0.26 to 0.92), reduced sleep efficiency (Hedges’ g -0.58; 95% CI -0.87 to -0.28), time in bed (Hedges’ g -0.64; 95% CI -1.02 to -0.26) and total sleep time (Hedges’ g -0.64; 95% CI -1.01 to -0.27). The analysis of subjective measures showed that they had more problems in daytime sleepiness (Hedges’ g 0.48; 95% CI 0.26 to 0.71), sleep latency (Hedges’ g 1.15; 95% CI 0.72 to 1.58), initiating and maintaining sleep (Hedges’ g 0.86; 95% CI 0.39 to 1.33) and sleep hyperhidrosis (Hedges’ g 0.48; 95% CI 0.29 to 0.66). Potential publication bias was detected for sleep latency, sleep period time and total sleep time measured by polysomnography. Some sleep alterations were moderated by age, sex and concurrent intellectual disability. The median NOS score was 8 (interquartile range 7.25-8.75). CONCLUSION: We found that medication-naïve children and adolescents with ASD presented significantly more subjective and objective sleep alterations compared to TD and identified possible moderators of these differences. Future research requires an analysis of how these sleep alterations are linked to core symptom severity and comorbid behavioural problems, which would provide an integrated therapeutic intervention for ASD. However, our results should be interpreted in light of the potential publication bias.

BACKGROUND: The COVID-19 pandemic has exacerbated the psychological burden on young people around the world and may have disproportionately large impacts for young people with disabilities. This review aims to systematically review the quantitative evidence on the impact of the COVID-19 pandemic on the mental health of young people with disabilities and evaluate the quality of included studies. METHODS: A systematic search was conducted using 5 electronic databases. The quality of the studies was assessed using the SIGN risk of bias assessment tool. A narrative synthesis was performed to synthesize the results of included studies. RESULTS: The initial search yielded 1935 studies, of which two met the eligibility criteria, one longitudinal study and one cross-sectional study, both assessed to be of low quality. In the cross-sectional study, young people with intellectual and developmental disabilities self-reported an increase in mental health symptoms. The longitudinal study found no evidence of a change in mental health symptoms from pre-pandemic to during the pandemic among young people with autism spectrum disorder, although these individuals reported negative impacts of the COVID-19 pandemic on their emotional or mental health. CONCLUSIONS: The findings of this review provide some weak evidence of a negative impact of the COVID-19 pandemic on the mental health of young people with disabilities. Importantly, the findings highlight the lack of research in this area. More research is needed to investigate the impact of the pandemic on the mental health of young disabled people, in order for governments to develop emergency preparedness plans to safeguard the well-being of this population.

Measurement of adaptive skills is important in the diagnosis, intervention planning, and progress monitoring of children with intellectual and developmental disabilities (IDD). Thus, ensuring accurate measurement, including measurement invariance, across children with and without IDD is critical. In this study, we evaluate the measurement invariance using multigroup confirmatory factor analysis (MG-CFA) of the Vineland-3 Comprehensive Interview (CIF) across children ages 6-21 years with and without IDD (N = 1,192) using archival data. Results showed that the Vineland-3 CIF exhibits configural invariance but may show some metric non-invariance in children with and without IDD. Suggestions for using the Vineland-3 CIF in this population are provided and future research and measure development needs are discussed.

Parenting styles and practices are crucial in promoting the self-determination of children. The purpose of the current study was to investigate the role of parenting styles and practices in enhancing the self-determination of children with/without intellectual and developmental disabilities (IDD). The present study was carried out with a sample of 243 parents of children with/without IDD in Türkiye (Turkey). The results indicated that an authoritative parenting style and autonomy-supportive parenting practices positively affect the degree of child self-determination, whereas permissive and overprotective parenting practices may limit child opportunities in fostering self-determination. The study results also showed that urbanization, higher income, and higher education level of parents positively impacted the degree of child self-determination. Parents of typically developing children reported higher levels of overall self-determination for their typically developing children when compared with children with intellectual disability and autism spectrum disorder. On the other hand, parents of children with mild disabilities reported a higher level of self-determination than both children with moderate and severe disabilities. The results were discussed within the cultural context of the current sample.

The aim of this study was to provide a descriptive overview of the social characteristics associated with Wiedemann-Steiner syndrome (WSS). A total of 24 parents of children/adults with WSS (11F, mean age = 12.94 years, SD = 8.00) completed the Social Responsiveness Scale 2nd Edition (SRS-2); Colorado Learning Difficulties Questionnaire (CLDQ) and Strengths and Difficulties Questionnaire (SDQ). Almost half our sample reported a diagnosis of autism spectrum disorder (ASD) and 70% had intellectual disability. On the SDQ, over 90% of participants were rated in borderline/clinical ranges in Peer Problems, yet the majority fell within normal limits in Prosocial Behaviors. Most fell in the moderate/severe difficulties ranges across SRS-2 Social Cognition, Communication, and Restricted/Repetitive Behaviors scales (all >70%); whereas substantially less participants met these ranges for deficits in Social Awareness (50%) and Social Motivation (33.33%). A pattern of relatively strong prosocial skills and social drive in the context of difficulties with inflexible behaviors, social cognition, and communication was observed, regardless of gender, ASD or intellectual disability diagnosis. The social phenotype associated with WSS is characterized by some autistic features paired with unusually high social motivation and prosocial tendencies.

Increased glutamate and glutamine levels and their relationship to astrocytes and dopaminergic transmissions in the brains of adults with autism. Sci Rep;2023 (Jul 19);13(1):11655.
Increased excitatory neuronal tones have been implicated in autism, but its mechanism remains elusive. The amplified glutamate signals may arise from enhanced glutamatergic circuits, which can be affected by astrocyte activation and suppressive signaling of dopamine neurotransmission. We tested this hypothesis using magnetic resonance spectroscopy and positron emission tomography scan with (11)C-SCH23390 for dopamine D1 receptors in the anterior cingulate cortex (ACC). We enrolled 18 male adults with high-functioning autism and 20 typically developed (TD) male subjects. The autism group showed elevated glutamate, glutamine, and myo-inositol (mI) levels compared with the TD group (p = 0.045, p = 0.044, p = 0.030, respectively) and a positive correlation between glutamine and mI levels in the ACC (r = 0.54, p = 0.020). In autism and TD groups, ACC D1 receptor radioligand binding was negatively correlated with ACC glutamine levels (r = - 0.55, p = 0.022; r = - 0.58, p = 0.008, respectively). The enhanced glutamate-glutamine metabolism might be due to astroglial activation and the consequent reinforcement of glutamine synthesis in autistic brains. Glutamine synthesis could underly the physiological inhibitory control of dopaminergic D1 receptor signals. Our findings suggest a high neuron excitation-inhibition ratio with astrocytic activation in the etiology of autism.

Autism spectrum disorder is a severe, life-prolonged neurodevelopmental disease typified by disabilities that are chronic or limited in the development of socio-communication skills, thinking abilities, activities, and behavior. In children aged two to three years, the symptoms of autism are more evident and easier to recognize. The major part of the existing literature on autism spectrum disorder is covered by a prediction system based on traditional machine learning algorithms such as support vector machine, random forest, multiple layer perceptron, naive Bayes, convolution neural network, and deep neural network. The proposed models are validated by using performance measurement parameters such as accuracy, precision, and recall. In this research, autism spectrum disorder prediction has been investigated and compared using common parameters such as application type, simulation method, comparison methodology, and input data. The key purpose of this study is to give a centralized framework to use for researchers working on autism spectrum disorder prediction. The best results were obtained by using the random forest algorithm as it performs better than other traditional machine learning algorithms. The achieved accuracy is 89.23%. The workflow representations of the investigated frameworks assist readers in comprehending the fundamental workings and architectures of these frameworks.

Maternal health during gestational period is undoubtedly critical in shaping optimal fetal development and future health of the offspring. Gestational diabetes mellitus is a metabolic disorder occurring in pregnancy with an alarming increasing incidence worldwide during recent years. Over the years, there is a growing body of evidence that uncontrolled maternal hyperglycaemia during pregnancy can potentially have detrimental effect on the neurodevelopment of the offspring. Both human and animal data have linked maternal diabetes with motor and cognitive impairment, as well as autism spectrum disorders, attention deficit hyperactivity disorder, learning abilities and psychiatric disorders. This review presents the available data from current literature investigating the relationship between maternal diabetes and offspring neurodevelopmental impairment. Moreover, possible mechanisms accounting for the detrimental effects of maternal diabetes on fetal brain like fetal neuroinflammation, iron deficiency, epigenetic alterations, disordered lipid metabolism and structural brain abnormalities are also highlighted. On the basis of the evidence demonstrated in the literature, it is mandatory that hyperglycaemia during pregnancy will be optimally controlled and the impact of maternal diabetes on offspring neurodevelopment will be more thoroughly investigated.

BACKGROUND: How best to improve the early detection of autism spectrum disorder (ASD) is the subject of significant controversy. Some argue that universal ASD screeners are highly accurate, whereas others argue that evidence for this claim is insufficient. Relatedly, there is no clear consensus as to the optimal role of screening for making referral decisions for evaluation and treatment. Published screening research can meaningfully inform these questions-but only through careful consideration of children who do not complete diagnostic follow-up. METHODS: We developed two simulation models that re-analyze the results of a large-scale validation study of the M-CHAT-R/F by Robins et al. (2014, Pediatrics, 133, 37). Model #1 re-analyzes screener accuracy across six scenarios, each reflecting different assumptions regarding loss to follow-up. Model #2 builds on this by closely examining differential attrition at each point of the multi-step detection process. RESULTS: Estimates of sensitivity ranged from 40% to 94% across scenarios, demonstrating that estimates of accuracy depend on assumptions regarding the diagnostic status of children who were lost to follow-up. Across a range of plausible assumptions, data also suggest that children with undiagnosed ASD may be more likely to complete follow-up than children without ASD, highlighting the role of clinicians and caregivers in the detection process. CONCLUSIONS: Using simulation modeling as a quantitative method to examine potential bias in screening studies, analyses suggest that ASD screening tools may be less accurate than is often reported. Models also demonstrate the critical importance of every step in a detection process-including steps that determine whether children should complete an additional evaluation. We conclude that parent and clinician decision-making regarding follow-up may contribute more to detection than is widely assumed.

BACKGROUND: Early parent-implemented intervention enhances parent-child interaction and improves language skills in children with autism spectrum disorders (ASD). Parent coaching is often delivered as standard care for children with ASD, where parents are taught to apply strategies in their child’s play activities and daily routines to achieve the prior stated goals. However, the ability to conduct parent coaching in physical in-clinic sessions is limited by resource constraints such as clinic space and therapist manpower. Furthermore, parents may experience difficulties with the generalisation of intervention strategies taught in the clinic to their natural home environments. In this study, telerehabilitation is evaluated as an alternative platform to deliver parent coaching for parent-implemented interventions to children with ASD in their homes. METHODS: This parallel-group, randomised, controlled, non-inferiority trial aims to evaluate the effectiveness of parent coaching delivered through video conferencing (telerehabilitation) versus in-clinic (standard care) delivery. Children aged 15 to 48 months (n = 200) who meet the cut-off score for ASD on the Autism Diagnostic Observation Schedule-2 are eligible. Parent-child dyads are randomly assigned to receive parent coaching either through weekly telerehabilitation or standard care. The primary outcome is the child’s development as measured by the subscale and composite scores of a standardised developmental assessment. Primary analysis will determine if the lower boundary of the 95% confidence interval for the mean difference in pre-post change between groups exceeds -5 (the non-inferiority margin). Secondary outcomes are the child’s adaptive behaviour, parent-child interaction, parental stress, and family quality of life. Outcomes will be measured pre-intervention, midterm, and post-intervention. Secondary analysis will determine if there is any between-group difference for the pre-post change in scores at the 5% significance level using two-sample t-test or Mann-Whitney U test. DISCUSSION: As a randomised controlled trial of a moderately large scale, this study will contribute to the limited existing literature on the effectiveness of parent coaching via telerehabilitation for early parent-implemented intervention for children with ASD. The results of this study will provide insights on whether telerehabilitation is comparable to conventional in-clinic parent coaching in enhancing parent-child interaction and improving language skills.

Autistic adults participate less and express lower satisfaction in leisure activities than nonautistic adults, although literature is limited. The multifaceted nature of leisure participation makes it challenging to measure, with most measures being retrospective. Ecological momentary assessments (EMA) can reduce recall bias. This pilot study assessed the feasibility and acceptability of EMA among autistic adults. Participants (N = 40) were recruited via email and online. After completing a baseline interview, participants were asked to complete a once-daily survey for 30 days, in which they received survey links through a text messaging smartphone app. Surveys asked participants to report whether they participated in any leisure activities during the day, their level of enjoyment, with whom they interacted, and where they participated. The EMA appeared feasible in this sample, as participants completed the daily survey on average 27.05 (SD = 3.92) days. Regarding acceptability, most agreed that survey timing was convenient, that it was easy to enter responses and answer questions daily, and that they had enough response time. Overall, this study supports the use of EMA methodology among autistic adults. Future research should follow and improve upon these EMA data collection practices to examine daily behavior and well-being among autistic adults.

We regularly infer other people’s thoughts and feelings from observing their actions, but how this ability contributes to successful social behavior and interactions remains unknown. We show that neural activation patterns during social inferences obtained in the laboratory predict the number of social contacts in the real world, as measured by the social network index, in three neurotypical samples (total n = 126) and one sample of autistic adults (n = 23). We also show that brain patterns during social inference generalize across individuals in these groups. Cross-validated associations between brain activations and social inference localize selectively to the right posterior superior temporal sulcus and were specific for social, but not nonsocial, inference. Activation within this same brain region also predicts autism-like trait scores from questionnaires and autism symptom severity. Thus, neural activations produced while thinking about other people’s mental states predict variance in multiple indices of social functioning in the real world.

19. Zukerman G, Yahav G, Ben-Itzchak E. After one year in university; a robust decrease in autistic traits reporting among autistic students. Front Psychiatry;2023;14:1146819.
BACKGROUND: Previous research on autistic students enrolled in university support programs has reported moderate improvement in anxiety/depression or adaptive behavior. However, alterations in autistic traits have not been examined. METHODS: This longitudinal study evaluated changes in university students’ autistic trait and state/trait anxiety levels. Participants were 24 neurotypically developed (ND) students with high levels of social anxiety symptoms (High SA), 30 ND students with low levels of SA symptoms (Low SA), and 41 autistic students (the primary focus of this study) residing with an ND peer student mentor as part of participating in the university’s integration support program. Autism spectrum quotient [AQ and State Trait Anxiety Inventory STAI] data were collected during the first semester of two consecutive academic years (T1, T2), as well as baseline (T1) levels of social anxiety, depression, and obsessive-compulsive symptoms. RESULTS: Significant interaction between group and time was observed, denoting a sharp decrease (2.9 SD) from T1 to T2 in the overall autistic trait level among the autistic group (AQ « attention switching » subscale demonstrating the most robust decrease), and a moderate decrease (0.5 SD) among the high SA group. Only for the autistic students were more compulsive symptoms at T1 associated with a lesser decrease in AQ scores (T1-T2), which in turn was negatively correlated with their T1 year-end grade point average. CONCLUSION: The findings suggest that attending post-secondary education (while partaking in a support/transition program) is followed by a profound change of the individual’s subjective experience of autism, characterized by a sharp decline in the level of autistic traits, particularly attention switching. This change is independent of alterations in well-being indices, such as anxiety, that are known to characterize students attending university.
