Children with autism spectrum disorder (ASD) face several challenges in the healthcare setting. This study defines the challenges experienced by children with autism in hospitals in Saudi Arabia. A cross-sectional study was conducted using a questionnaire for guardians of autistic children in outpatient clinics, autism support groups, and rehabilitation centers. A total of 199 participants were included. The medical procedures causing the most anxiety to children were injections and getting their blood drawn (68.3%), vital sign measurement (41.6%), and height and weight measurement (37.8%). Long waiting hours (44.1%), increased sensory stimuli (33.2%), and overcrowding of hospital staff (27.9%) were stress-inducing in the healthcare environment. The guardians recommended that loud noises (44.7%), crowdedness (41.2%), and long waiting hours (42.1%) be avoided. The nonverbal children experienced significantly higher levels (p < 0.001) of agitation, irritability, and outbursts during doctor visits than their verbal counterparts. The children with intellectual disabilities were more tense and unresponsive during doctor visits (33.3%) than their intellectually able counterparts, who more frequently were calm and responsive (44.9%) during visits. Most patients with ASD face hardships during hospital visits. Nonverbal patients and those with intellectual disabilities have a higher tendency for hospital setting anxiety-induced outbursts, which may be eased by avoiding loud noise and overcrowding.

PURPOSE: Although social media platforms have made information about autism more accessible to the general public, concerns have been raised about the unfiltered nature of the content they host. In the current study, we examined the reach and accuracy of videos providing informational content about autism on TikTok, a popular social media platform. METHODS: We examined engagement indicators (including views and « likes ») for the TikTok videos associated with the #Autism hashtag. Two coders independently fact-checked informational content of the most viewed videos from the #Autism hashtag videos and coded it as either accurate, inaccurate or ‘overgeneralization’ based on the consistency of the information in the videos with current knowledge on autism. RESULTS: Videos associated with the « #Autism » hashtag accrued 11.5 billion views collectively. An examination of the top 133 videos providing informational content on autism, which totaled 198.7 million views and 25.2 million likes, showed that 27% of the videos were classified as accurate, while 41% were classified as inaccurate and 32% as overgeneralized. There were no significant differences in engagement between accurate and inaccurate/overgeneralized videos. Videos created by healthcare professionals were more likely to include accurate information. CONCLUSION: The informational content about autism made available on TikTok reaches a wide number of people. Most of the information provided, however, appears to be misaligned with current knowledge. It is important for healthcare providers and other professionals to be aware of the autism-related content being shared on TikTok so that they can better engage with the large community of TikTok users.

BACKGROUND: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders in which the underlying pathogenesis and etiologic factors are not fully understood. The blood brain barrier (BBB) plays a critical role in central nervous system defense by limiting access to circulating solutes, macromolecules, and cells that can negatively affect neuronal activity. The loss of BBB integrity is likely to be seen as a common pathologic finding for many psychiatric disorders such as schizophrenia, ASD, and mood disorders. In this study, we aimed to investigate whether serum Cingulin levels are associated with ASD. SUBJECTS AND METHODS: A total of 40 treatment-naive children with ASD and 40 healthy controls were included in the present study. The Schedule for Affective Disorders and Schizophrenia for School-Aged Children, Present and Lifetime Version-DSM-5 (K-SADS-PL-DSM-5) has been used to screen healthy controls for psychiatric disorders by a psychiatrist after a physical examination by a paediatrician. The clinical severity of the ASD symptoms has been assessed by the Childhood Autism Rating Scale (CARS). Venous blood samples were collected and serum Cingulin levels were measured. RESULTS: When the ASD and control groups were compared, CARS and Cingulin values of the patient group were statistically higher than the healthy group. There is a statistically positive correlation between CARS and Cingulin values. DISCUSSION: To the best of our knowledge, this study is a first in the literature conducted about the serum Cingulin levels, which is a component of BBB, among patients with ASD. Our findings demonstrate that serum Cingulin levels are meaningfully higher in ASD group compared to the healthy control group. It has been also indicated that there has been a meaningful relationship between serum Cingulin levels and ASD symptom severity.

Objective: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders with underlying pathogenesis and etiological factors not fully understood. We assumed that galectin-3, which is also linked with inflammatory responses, may be central to the ethiopathogenesis of ASD. Method: The current study consisted of 33 psychotropic medication-naive children with ASD and 32 control subjects. The Schedule for Affective Disorders and Schizophrenia for School-Aged Children, Present and Lifetime Version-DSM-5 (K-SADS-PL-DSM-5) was used to screen healthy controls for psychiatric disorders by a psychiatrist after a physical examination by a pediatrician. The clinical severity of the ASD symptoms has been assessed by the Childhood Autism Rating Scale (CARS). Venous blood samples were collected and serum galectin-3 levels were measured. Results: When the ASD and control groups are compared, the mean galectin-3 level is 417.77 (SD = 200.20) in the ASD group and 243.08 (SD = 64.65) in the control group, and there is a statistically significant difference between the groups (p < 0.001). When examining whether there is a correlation between galectin-3 levels and CARS total scores, no statistically significant correlation was found between them (r = 0.015, p = 0.933). Discussion: In this study, we examined whether serum galectin-3 levels have a relation with ASD in childhood or not. Our findings have indicated that the children with ASD have higher serum galectin-3 levels compared to the controls. However, no significant relationship has been found between serum galectin-3 levels and ASD symptom severity.

5. Busch SE, Simmons DH, Gama E, Du X, Longo F, Gomez CM, Klann E, Hansel C. Overexpression of the autism candidate gene Cyfip1 pathologically enhances olivo-cerebellar signaling in mice. Front Cell Neurosci;2023;17:1219270.
Cyfip1, the gene encoding cytoplasmic FMR1 interacting protein 1, has been of interest as an autism candidate gene for years. A potential role in autism spectrum disorder (ASD) is suggested by its location on human chromosome 15q11-13, an instable region that gives rise to a variety of copy number variations associated with syndromic autism. In addition, the CYFIP1 protein acts as a binding partner to Fragile X Messenger Ribonucleoprotein (FMRP) in the regulation of translation initiation. Mutation of FMR1, the gene encoding FMRP, causes Fragile X syndrome, another form of syndromic autism. Here, in mice overexpressing CYFIP1, we study response properties of cerebellar Purkinje cells to activity of the climbing fiber input that originates from the inferior olive and provides an instructive signal in sensorimotor input analysis and plasticity. We find that CYFIP1 overexpression results in enhanced localization of the synaptic organizer neurexin 1 (NRXN1) at climbing fiber synaptic input sites on Purkinje cell primary dendrites and concomitant enhanced climbing fiber synaptic transmission (CF-EPSCs) measured using whole-cell patch-clamp recordings from Purkinje cells in vitro. Moreover, using two-photon measurements of GCaMP6f-encoded climbing fiber signals in Purkinje cells of intact mice, we observe enhanced responses to air puff stimuli applied to the whisker field. These findings resemble our previous phenotypic observations in a mouse model for the human 15q11-13 duplication, which does not extend to the Cyfip1 locus. Thus, our study demonstrates that CYFIP1 overexpression shares a limited set of olivo-cerebellar phenotypes as those resulting from an increased number of copies of non-overlapping genes located on chromosome 15q11-13.

6. Cherewick M, Daniel C, Shrestha CC, Giri P, Dukpa C, Cruz CM, Rai RP, Matergia M. Psychosocial interventions for autistic children and adolescents delivered by non-specialists in low- and middle-income countries: a scoping review. Front Psychol;2023;14:1181976.
BACKGROUND: Most autistic individuals reside in low- and middle-income countries (LMIC) and have limited access to medical providers and specialists. Support for delivery of psychosocial interventions by non-specialists is growing to address this mental health care gap. This scoping review involved a systematic analysis of studies of non-specialist delivered psychosocial interventions for children and adolescents diagnosed with autism and living in low- and middle-income countries. METHODS: The primary objective of this review was to identify psychosocial interventions for autistic children and adolescents in LMIC delivered by non-specialists (parent, teacher, peer, community, multi-level) and to summarize resulting effects on targeted outcomes. The search strategy was completed in four databases with predetermined inclusion and exclusion criteria. The systematic search generated 3,601 articles. A total of 18 studies met inclusion/exclusion criteria. Data extraction was completed, and results summarized by; (1) participant sample; (2) intervention procedures; (3) implementation by non-specialists; (4) effect on evaluated outcomes; and (5) assessment of risk of bias. Studies examined a range of child and adolescent outcomes including assessment of communication skills, social skills, motor skills, functional and adaptive behaviors, emotional regulation, attention and engagement, sensory challenges, depression, anxiety, and quality of life. Several studies also evaluated intervention effects on family relationships, parent/caregiver stress and parent/caregiver mental health. RESULTS: Collectively, the 18 studies included a total of 952 ASC participants ranging in age from 2 to 16 years. Of the included studies, 8 studies were parent/caregiver-mediated, 1 study was peer-mediated, 2 studies were teacher-mediated, and 7 studies included multi-level non-specialist mediated components. Effects on evaluated outcomes are reported. CONCLUSION: Non-specialist delivered interventions for autistic children and adolescents are effective for an array of outcomes and are particularly well suited for low- and middle-income countries. Implications for future research are discussed.

The mediating effect of mood spectrum on the relationship between autistic traits and catatonia spectrum. Front Psychiatry;2023;14:1092193.
BACKGROUND: In the recent years, several studies have shown a correlation between autism spectrum disorder (ASD) and catatonia. It is also known that both conditions are found to be associated with mood disorders. This study aimed to investigate the relationship between autistic traits and catatonic symptoms, as well as the potential mediating role of mood disorder spectrum in the relationship between them. METHODS: The total sample of 514 subjects was composed by four diagnostic groups, composed by patients affected by catatonia (CTN), borderline personality disorder (BPD), major depressive disorder (MDD) and healthy controls (HC). Subjects were assessed with the SCID-5-RV, the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Catatonia Spectrum (CS) and the Mood Spectrum Self-Report (MOODS-SR). Statistical analyses included Pearson’s coefficient calculation, multiple linear regression, and mediation analysis. RESULTS: all the correlations appear to be strongly positive and significant with the strongest coefficient emerging between AdAS Spectrum total score and CS total score (r = 0.762, p < 0.001). The Mediation Analysis showed that AdAS Spectrum total score showed a significant indirect effect on CS total score through MOODS-SR total score (b = 0.168, 95% bootstrapped CI [0.127:0.207]). CONCLUSION: The present study highlights the presence of a mediating role of the mood disorder spectrum in the relationship between autistic traits and the catatonia spectrum.

8. Dell’Osso L, Amatori G, Cremone IM, Massimetti E, Nardi B, Gravina D, Benedetti F, Muscatello MRA, Pompili M, Politi P, Vita A, Maj M, Carpita B. Autistic and Catatonic Spectrum Symptoms in Patients with Borderline Personality Disorder. Brain Sci;2023 (Aug 7);13(8)
BACKGROUND: Recent literature has shown that a considerable percentage of patients with severe mental disorders can develop, over time, full-blown or subthreshold catatonia. Some studies corroborate the model of an illness trajectory in which different mental disorders would be arranged along a continuum of severity until the development of catatonia. In such an illness pathway, autistic traits (AT) and borderline personality disorder (BPD) may represent important steps. In order to further explore the association between AT, BPD, and catatonia, the aim of this study was to compare catatonic spectrum symptoms and AT among patients with major depressive disorder (MDD), BPD, and healthy controls (CTL), also evaluating possible predictive dimensions of the different diagnoses. METHODS: A total of 90 adults affected by BPD, 90 adults with a diagnosis of MDD, and 90 CTL, homogeneous in terms of gender and age, were recruited from six Italian university departments of psychiatry and assessed with the SCID-5-RV, the Catatonia Spectrum (CS), and the Adult Autism Subthreshold Autism Spectrum (AdAS Spectrum). RESULTS: The total CS score was significantly higher in the BPD and MDD groups than in the CTL group, while the majority of CS domain scores were significantly higher in the BPD group than in the MDD group, which scored significantly higher than the CTL group. The total AdAS Spectrum score and the AdAS Spectrum domain scores were significantly higher in the BPD group than in the MDD group, which in turn scored significantly higher than the CTL group. The CS domains « psychomotor activity » and « impulsivity », and AdAS Spectrum domains « verbal communication », « empathy », and « hyper-/hyporeactivity to sensory input » were associated with the risk of presenting a diagnosis of BPD.

Despite many differences, autism spectrum disorder and schizophrenia spectrum disorder share environmental risk factors, genetic predispositions as well as neuronal abnormalities, and show similar cognitive deficits in working memory, perspective taking, or response inhibition. These shared abnormalities are already present in subclinical traits of these disorders. The literature proposes that changes in the inhibitory GABAergic and the excitatory glutamatergic system could explain underlying neuronal commonalities and differences. Using magnetic resonance spectroscopy ((1)H-MRS), we investigated the associations between glutamate concentrations in the anterior cingulate cortex (ACC), the left/right putamen, and left/right dorsolateral prefrontal cortex and psychotic-like experiences (Schizotypal Personality Questionnaire) and autistic traits (Autism Spectrum Quotient) in 53 healthy individuals (26 women). To investigate the contributions of glutamate concentrations in different cortical regions to symptom expression and their interactions, we used linear regression analyses. We found that only glutamate concentration in the ACC predicted psychotic-like experiences, but not autistic traits. Supporting this finding, a binomial logistic regression predicting median-split high and low risk groups for psychotic-like experiences revealed ACC glutamate levels as a significant predictor for group membership. Taken together, this study provides evidence that glutamate levels in the ACC are specifically linked to the expression of psychotic-like experiences, and may be a potential candidate in identifying early risk individuals prone to developing psychotic-like experiences.

10. Garcia-Molina I, Rodríguez-Clavell P. Moral judgements among neurotypical children, autistic children and adults with intellectual disability. Int J Dev Disabil;2023;69(5):767-774.
Background: The present study investigates the possible differences between neurotypical children (NT), autistic children, and adults with intellectual disability (ID) related to (i) morality of the agent, (ii) morality of the action, and (iii) culpability in inappropriate situations. Method: Eighty-four Spanish participants (32 NT, 30 autistic children, and 22 adults with ID) responded to a task of moral transgression with an unambiguous structure (bad intention – bad outcome), where the stories were classified as first-order Theory of Mind (ToM) (based on simple desires) and second-order ToM (based on revenge). Results: Autistic group judged similarly to NT group. However, adults with ID had greater difficulty judging the (ii) morality of the action (compared with the autistic and NT group) and (iii) culpability (compared with the NT group). Also, ID adults encountered problems responding the moral questions in the balloon story (second-order ToM) and ice-cream story (first-order ToM). Conclusions: Autistic and NT children were able to make similar moral judgements, however adults with ID did not respond in the same way – as they were more benevolent in their judgements.

11. Gates JA, McNair ML, Richards JK, Lerner MD. Social Knowledge & Performance in Autism: A Critical Review & Recommendations. Clin Child Fam Psychol Rev;2023 (Aug 6)
Autistic social challenges have long been assumed to arise from a lack of social knowledge (« not knowing what to do »), which has undergirded theory and practice in assessment, treatment, and education. However, emerging evidence suggests these differences may be better accounted for by difficulties with social performance (« doing what they may know »). This distinction has important implications for research, practice, policy, and community support of autistic people. This review examines the theoretical and clinical implications and empirical status of the knowledge-performance distinction in autism. Current evidence suggests that social knowledge deficits are neither definitional nor reliably related to outcomes in autism. Prioritizing social knowledge, then, may produce unanticipated, problematic consequences in terms of accuracy of assessment, intervention effectiveness, and promotion of stigma. It may also yield unrealistic expectations around the value of knowledge for autistic people and their families, yielding important ethical considerations. Conversely, recent evidence highlights performance-related factors as being especially promising for better modeling and addressing social challenges in autism. Prioritizing performance, then, may offer new directions for assessment, substantially different intervention opportunities, and novel methods of inclusion and affirmation. This review touches upon each of these domains and implications, integrates these developments with broader models of social competence in youth, and provides direction for future research and practice regarding social competence in autism.

Psychotropic drugs are often used to treat behavior problems in ASD with some evidence supporting efficacity (e.g.: risperidone and irritability) but also significant side effects at the short and longer-term. It is then essential to know better the factors associated with the prescription of these medications and potentially implement early behavioral and psychosocial intervention or cognitive remediation before to use medication. We designed a case-control study based on the population of the ELENA cohort to assess the factors associated with early psychotropic drugs use in children with ASD. Externalized behavior symptoms (measured by the Child Behavior Checklist) is the leading risk factor during the first years of follow-up (aOR = 2.8; CI [1.04; 7.67]; p = 0.04). Age, gender, autism severity, adaptive behaviors, or internalized behaviors were not associated with psychotropic medication prescription. Low IQ and parents who had received training tended to increase the risk of psychotropic medication prescription during follow-up but were not statistically significant. These findings underscore the need for early identification of symptoms of externalizing behaviour, early appropriate information for parents about treatment with and without medication, early analysis of externalising behaviour and targeted treatments.

BACKGROUND AND AIMS: Guidelines regarding social cognitive interventions for autistic children suggest incorporating a holistic approach. This includes increasing the family’s understanding of difficulties associated with autism, integrations of natural environments, and parents as active agents in the intervention while being supported for their well-being. The current availability of holistic parent-implemented interventions for autistic children is limited, with no qualitative understanding of how parents view the benefits for themselves or their children. METHOD: The current study expands the literature regarding holistic approaches through a qualitative understanding of parent perceptions of a parent-implemented social communication intervention for autistic children (TalkAbility™), which incorporates a 6-month follow-up. This study sought to gain a deeper understanding from parents on their perceptions of a holistic approach, including the impact on themselves, their families, and their autistic child. RESULTS: Following Braun and Clarke’s model of thematic analysis, data was coded into four themes: (a) communication difficulties, frustrations, and progress, (b) social relationships and concerns, (c) communication strategies, and (d) thoughts and emotions surrounding TalkAbility™. CONCLUSIONS: Parents report that many components of a holistic approach are instrumental in encouraging social communication in their autistic child. Results highlight the importance of considering parent experiences regarding interventions for their child’s social communication skills through a qualitative viewpoint. IMPLICATIONS: Knowing the intervention aspects that parents view as most valuable allows targeted program modifications that reflect actual parent needs. Further understanding regarding the influence of holistic parent-implemented social communication interventions on child communication skills, parenting frustrations, and parent-child relationships is needed.

BACKGROUND: Social anxiousness is a pervasive symptom in both social anxiety disorder and autism spectrum conditions. Binocular rivalry, which occurs when different images are presented to each eye, has been used to explore how visual and cognitive processing differs across various clinical diagnoses. Previous studies have separately explored whether individuals with autism or anxiety experience binocular rivalry in ways that are different from neurotypical individuals. METHODS: We applied rivalry paradigms that are similar to those used in previous studies of autism and general anxiety to individuals experiencing symptoms of social anxiousness at clinical or subclinical levels. We also incorporated rivalrous stimuli featuring neutral and emotional facial valances to explore potential overlap of social processing components in social anxiety and autism. RESULTS: We hypothesized that higher levels of social anxiousness would increase binocular rivalry switch rates and that higher levels of autistic traits would decrease switch rates. However, stimulus condition did not affect switch rates in either diagnostic group, and switch rate was not significantly predictive of dimensional measures of either autism or social anxiety. DISCUSSION: This may suggest a common mechanism for atypical visual cognition styles previously associated with social anxiety and autism. Alternatively, differences in switch rates may only emerge at higher trait levels than reported by the participants in our studies. Furthermore, these findings may be influenced by sex differences in our unique sample.

BACKGROUND: Unravelling the relationships between candidate genes and autism spectrum disorder (ASD) phenotypes remains an outstanding challenge. Endophenotypes, defined as inheritable, measurable quantitative traits, might provide intermediary links between genetic risk factors and multifaceted ASD phenotypes. In this study, we sought to determine whether plasma metabolite levels could serve as endophenotypes in individuals with ASD and their family members. METHODS: We employed an untargeted, high-resolution metabolomics platform to analyse 14,342 features across 1099 plasma samples. These samples were collected from probands and their family members participating in the Autism Genetic Resource Exchange (AGRE) (N = 658), compared with neurotypical individuals enrolled in the PrecisionLink Health Discovery (PLHD) program at Boston Children’s Hospital (N = 441). We conducted a metabolite quantitative trait loci (mQTL) analysis using whole-genome genotyping data from each cohort in AGRE and PLHD, aiming to prioritize significant mQTL and metabolite pairs that were exclusively observed in AGRE. FINDINGS: Within the AGRE group, we identified 54 significant associations between genotypes and metabolite levels (P < 5.27 × 10(-)(11)), 44 of which were not observed in the PLHD group. Plasma glutamine levels were found to be associated with variants in the NLGN1 gene, a gene that encodes post-synaptic cell-adhesion molecules in excitatory neurons. This association was not detected in the PLHD group. Notably, a significant negative correlation between plasma glutamine and glutamate levels was observed in the AGRE group, but not in the PLHD group. Furthermore, plasma glutamine levels showed a negative correlation with the severity of restrictive and repetitive behaviours (RRB) in ASD, although no direct association was observed between RRB severity and the NLGN1 genotype. INTERPRETATION: Our findings suggest that plasma glutamine levels could potentially serve as an endophenotype, thus establishing a link between the genetic risk associated with NLGN1 and the severity of RRB in ASD. This identified association could facilitate the development of novel therapeutic targets, assist in selecting specific cohorts for clinical trials, and provide insights into target symptoms for future ASD treatment strategies. FUNDING: This work was supported by the National Institute of Health (grant numbers: R01MH107205, U01TR002623, R24OD024622, OT2OD032720, and R01NS129188) and the PrecisionLink Biobank for Health Discovery at Boston Children's Hospital.

BACKGROUND: Pragmatic language, or the use of language in social contexts, is a critical skill in daily life, supporting social interactions and the development of meaningful social relationships. Pragmatic language is universally impacted in autism spectrum disorder (ASD) and pragmatic deficits are also common in other neurodevelopmental conditions, particularly those related to ASD, such as fragile X syndrome (FXS). This study used a multi-method, longitudinal approach to characterize potentially unique pragmatic profiles across different neurodevelopmental disabilities, and across contexts that varied in degree of social demand. The utility of computational linguistic analyses, as an efficient tool for capturing pragmatic abilities, was also explored. METHODS: Pragmatic skills of boys with idiopathic ASD (ASD-O, n = 43), FXS with and without ASD (FXS-ASD, n = 57; FXS-O, n = 14), Down syndrome (DS, n = 22), and typical development (TD, n = 24) were compared using variables obtained from a standardized measure, narrative, and semi-naturalistic conversation at up to three time points. RESULTS: Pragmatic language was most significantly impacted among males with ASD-O and FXS-ASD across all three contexts, with more difficulties in the least structured context (conversation), and also some differences based on FXS comorbidity. Patterns of group differences were more nuanced for boys with FXS-O and DS, with context having less of an impact. Clinical groups demonstrated minimal changes in pragmatic skills with age, with some exceptions. Computational language measurement tools showed some utility for measuring pragmatic skills, but were not as successful as traditional methods at capturing differences between clinical groups. CONCLUSION: Overlap and differences between ASD and other forms of neurodevelopmental disability in general, and between idiopathic and syndromic ASD in particular, have important implications for developing precisely tailored assessment and intervention approaches, consistent with a personalized medicine approach to clinical study and care in ASD.

BACKGROUND: Gut microbiota plays a potential role in human health and different disorders such as autism spectrum disorder (ASD). Therefore, we analyzed gut bacteria composition in children with ASD and typical development (TD), and its relationship with nutritional status and dietary intake. METHODS: A descriptive cross-sectional study was carried out in 3- to 12-year-old children (ASD = 30, TD = 28). Dietary intake (applying food frequency questionnaires) and body mass index-for-age (expressed in z-score) were determined. Children were divided into normal weight and excess weight (risk of overweight + overweight + obesity), and the ASD group was categorized into gluten- and casein-free diet (ASD-diet) or no diet (ASD-no diet). The relative abundance of gut bacteria was analyzed in fecal samples by 16S rRNA sequencing. RESULTS: Children with excess weight had lower Roseburia than normal weight. Fewer Bifidobacterium longum and higher Clostridium glycolicum were found in the ASD group compared with TD one. Participants with excess weight and ASD had lower Roseburia and Faecalibacterium prausnitzii and higher Eubacterium ventricosum and Flavonifractor plautii than the TD group with the same nutritional status. Positive and negative associations were found between the bacteria genus and species, and the intake of dairy, vegetable drinks, cereals with and without gluten, food source of proteins, fish, food source of fat, and coconut oil, in unadjusted models and after adjustment for age, diet/no diet, ASD/TD. CONCLUSION: Significant differences in microbial community composition were found between children with ASD and TD, considering their nutritional status and dietary intake.

Sleep is vital to many processes involved in the well-being and health of children; however, it is estimated that 80% of children with Rett syndrome suffer from sleep disorders. Caregiver reports and questionnaires, which are the current method of studying sleep, are prone to observer bias and missed information. Polysomnography is considered the gold standard for sleep analysis but is labor and cost-intensive and limits the frequency of data collection for sleep disorder studies. Wearable digital health technologies, such as actigraphy devices, have shown potential and feasibility as a method for sleep analysis in Rett syndrome, but have not been validated against polysomnography. Furthermore, the collected accelerometer data has limitations due to the rigidity, periodic limb movement, and involuntary muscle contractions prevalent in Rett syndrome. Heart rate and electrodermal activity, along with other physiological signals, have been linked to sleep stages and can be utilized with machine learning to provide better resistance to noise and false positives than actigraphy. This research aims to address the gap in Rett syndrome sleep analysis by comparing the performance of a machine learning model utilizing both accelerometer data and physiological data features to the gold-standard polysomnography for sleep analysis in Rett syndrome. Our analytical validation pilot study (n = 7) found that using physiological and accelerometer features, our machine learning models can differentiate between awake, non-rapid eye movement sleep, and rapid eye movement sleep in Rett syndrome children with an accuracy of 85.1% when using an individual model. Additionally, this work demonstrates that it is feasible to use digital health technologies in Rett syndrome, even at a young age, without data loss or interference from repetitive movements that are characteristic of Rett syndrome.

BACKGROUND: Occupational Therapy is among the top interventions for autistic children, hence the need for equitable and effective services in the public and private health and education sectors. Ongoing research into the therapies for autism spectrum disorders in different contexts is also required. OBJECTIVES: To explore and describe occupational therapists’ assessment and intervention for autistic children in South Africa. METHODS: A descriptive qualitative research design using semi-structured interviews to gather data from purposively recruited OTs (n=20). Data were audio-recorded, transcribed and analysed thematically, and compared across three sectors public health, special needs schools and private practice. RESULTS: South African practice across all three sectors was similar to international patterns of informal play-based assessment, sensory processing and Ayres Sensory Integration (ASI®) treatment. Developmental frameworks guided specific approaches. Strong team collaboration was present across sectors, with some transdisciplinary teamwork and co-treatment. Undergraduate and postgraduate training opportunities were, however limited. CONCLUSIONS: Occupational therapy assessments had diagnostic value. Informal tools such as developmental checklists were found to have clinical utility, whilst standardised tools were most commonly used to assess sensory processing and visual perception. Recommendations included incorporating ASI® into undergraduate curricula and postgraduate training opportunities with multidisciplinary input to develop ASD professionals in South Africa. It is imperative to advocate for services in under-resourced rural areas and marginalised communities that lack financial and social resources. Occupational therapists need to find new ways of working collaboratively across sectors to ensure effective and comprehensive services in public health and special schools.

Autism spectrum disorder (ASD) comprises a wide range of neurodevelopment conditions primarily characterized by impaired social interaction and repetitive behavior, accompanied by a variable degree of neuropsychiatric characteristics. Synaptic dysfunction is undertaken as one of the key underlying mechanisms in understanding the pathophysiology of ASD. The excitatory/inhibitory (E/I) hypothesis is one of the most widely held theories for its pathogenesis. Shifts in E/I balance have been proven in several ASD models. In this study, we investigated three mouse lines recapitulating both idiopathic (the BTBR strain) and genetic (Fmr1 and Shank3 mutants) forms of ASD at late infancy and early adulthood. Using receptor autoradiography for ionotropic excitatory (AMPA and NMDA) and inhibitory (GABA(A)) receptors, we mapped the receptor binding densities in brain regions known to be associated with ASD such as prefrontal cortex, dorsal and ventral striatum, dorsal hippocampus, and cerebellum. The individual mouse lines investigated show specific alterations in excitatory ionotropic receptor density, which might be accounted as specific hallmark of each individual line. Across all the models investigated, we found an increased binding density to GABA(A) receptors at adulthood in the dorsal hippocampus. Interestingly, reduction in the GABA(A) receptor binding density was observed in the cerebellum. Altogether, our findings suggest that E/I disbalance individually affects several brain regions in ASD mouse models and that alterations in GABAergic transmission might be accounted as unifying factor.

Present study was designed to evaluate the efficacy and safety of l-carnitine as an adjuvant agent to risperidone in the treatment of autism spectrum disorder (ASD)-associated behaviors. In this study, 68 children with confirmed ASD were randomly allocated to receive either l-carnitine (150 mg/day) or matched placebo in addition to risperidone. We utilized the Aberrant Behavior Checklist-Community Edition scale (ABC-C) and a checklist of potential adverse effects to assess changes in behavioral status and safety profile at weeks 0, 5 and 10 of the trial. The primary outcome was defined as a change in the irritability subscale score. Sixty patients with similar baseline characteristics completed the trial period. Although scores of ABC-C subscales significantly decreased in both groups over the trial period, the combination of l-carnitine and risperidone resulted in more reduction on the irritability and hyperactivity subscales compared to the combination of risperidone and placebo (P = 0.033 and P < 0.001, respectively). However, changes in lethargy, stereotypic behavior and inappropriate speech subscales were similar between groups. In conclusion, l-carnitine adjuvant to risperidone could improve irritability and hyperactivity features in children with ASD. Results of this study should be considered preliminary and further clinical trials with larger sample sizes and longer follow-up periods are warranted.

The neuronal differences contributing to the etiology of autism spectrum disorder (ASD) are still not well defined. Previous studies have suggested that myelin and axons are disrupted during development in ASD. By combining structural and diffusion MRI techniques, myelin and axons can be assessed using extracellular water, aggregate g-ratio, and a novel metric termed aggregate conduction velocity, which is related to the capacity of the axon to carry information. In this study, several innovative cellular microstructural methods, as measured from magnetic resonance imaging (MRI), are combined to characterize differences between ASD and typically developing adolescent participants in a large cohort. We first examine the relationship between each metric, including microstructural measurements of axonal and intracellular diffusion and the T1/T2 ratio. We then demonstrate the sensitivity of these metrics by characterizing differences between ASD and neurotypical participants, finding widespread increases in extracellular water in the cortex and decreases in aggregate g-ratio and aggregate conduction velocity throughout the cortex, subcortex, and white matter skeleton. This study is the first to reveal that ASD involves differences of myelin and axonal development with implications for neuronal function. We also introduce a novel neuroimaging metric, aggregate conduction velocity, that is highly sensitive to these changes. We conclude that ASD may be characterized by otherwise intact structural connectivity but that functional connectivity may be attenuated by network properties affecting neural transmission speed. This effect may explain the putative reliance on local connectivity in contrast to more distal connectivity observed in ASD.

BACKGROUND: The purpose of this study was to describe the anomalies observed on imaging for developmental delay in black African children. METHODS: It was a descriptive cross-sectional study, which included children aged between 1 month to 6 years with developmental delay and had done a brain MRI and/or CT scan. RESULTS: We included 94 children, 60.6% of whom were males. The mean age was 32.5 ± 6.8 months. A history of perinatal asphyxia found in 55.3% of cases. According to the Denver developmental II scale, profound developmental delay observed in 35.1% of cases, and severe developmental delay in 25.5%. DD was isolated in 2.1% of cases and associated with cerebral palsy, pyramidal syndrome, and microcephaly in respectively 83%, 79.8%, and 46.8% of cases. Brain CT scan and MRI accounted for 85.1% and 14.9% respectively. The tests were abnormal in 78.7% of the cases, and cerebral atrophy was the preponderant anomaly (cortical atrophy = 80%, subcortical atrophy = 69.3%). Epileptic patients were 4 times more likely to have abnormal brain imaging (OR = 4.12 and p = 0.05),. We did not find a link between the severity of psychomotor delay and the presence of significant anomalies in imaging. CONCLUSION: In our context, there is a high prevalence of organic anomalies in the imaging of psychomotor delay, which were dominated by cerebral atrophy secondary to hypoxic ischemic events.

The COVID-19 pandemic has significantly impacted caregivers, especially those raising a child with an intellectual/developmental disability (IDD). While research has shown substantial disruption to the family, school, and occupational lives of the IDD community, little is known about the long-term impacts of COVID-19. To address this question, 249 caregivers were surveyed via an online questionnaire, between April and August of 2022 (more than 2 years into the pandemic) about potential impacts of the COVID-19 pandemic on their child’s access to health- and school-based therapeutic services, caregiver mental health, and family life. The majority of caregivers reported disruptions in access to and quality of school-based therapeutic services for their child as well as a reduction in educational accommodations in the 2021-2022 academic year. Nearly half of caregivers reported feeling anxious and almost a quarter reported feeling depressed for the majority of their days. More than half of respondents reported decreased social support, and one-fifth reported employment disruptions and decreased access to food. These findings suggest that families of children with IDD are still experiencing ongoing negative impacts of the pandemic, emphasizing the critical need for continued support in the wake of the initial and more obvious disruptions caused by the COVID-19 outbreak.

Children with Autism Spectrum Disorder (ASD) demonstrate motor skill deficits in comparison to their neurotypically developing peers. However, it is unknown whether these motor skill deficits persist into adulthood. We evaluated skipping kinematics and motor performance in college students with and without ASD. We collected kinematic data from 20 college students, 10 with ASD and 10 without ASD, using a 12-camera three-dimensional motion capture system while participants completed three skipping trials. We scored skipping performance using Everyone Can! and the Halverson Developmental Sequences for Skipping, and we processed data using Cortex, Visual 3D, and MATLAB. We extracted data for center of mass excursion, peak velocity of joint extension, and peak joint angles of the hip, knee, and ankle of the dominant leg. Independent t-tests and Mann-Whitney U tests were used to examine differences between groups with an alpha level of p ≤ 0.05. We found no statistically significant differences for peak sagittal plane joint angles, velocities, or vertical center of mass excursion. However, the ASD group demonstrated greater medio-lateral center of mass displacement (ASD M = .08, SD = .1 m; Control M = .03, S = .03 m; p = .026) and greater frontal plane knee excursion (ASD M = 11.49, SD = 6.23°; Control M = 5.29, SD = 2.44°; p = .01) than participants without ASD. Similarly, the ASD group performed less proficiently in skipping than the group without ASD, as assessed by the developmental scoring methods (Everyone Can! composite score medians [interquartile range]: ASD M = 10.5, SD = 8; Control M = 15.0, SD = 0, p = .008). Despite many similarities in skipping kinematics between groups, participants with ASD were less proficient in skip performance than participants without ASD. Interventions for individuals with ASD addressing skipping proficiency or the performance of other locomotor skills, such as running and jumping, may promote participation in activities that involve complex motor skills and help individuals with ASD lead more physically active lives.

Alterations of natural killer cells activatory molecules phenotype and function in mothers of ASD children: a pilot study. Front Immunol;2023;14:1190925.
INTRODUCTION: Autism spectrum disorder (ASD) is accompanied by complex immune alterations and inflammation, and the possible role played by Natural Killer (NK) in such alterations is only barely understood. METHODS: To address this question we analysed activating and inhibitory NK receptors, as well as NK cells phenotype and function in a group of mothers of children who developed ASD (ASD-MO; N=24) comparing results to those obtained in mothers of healthy children who did not develop (HC-MO; N=25). RESULTS: Results showed that in ASD-MO compared to HC-MO: 1) NK cells expressing the inhibitory receptor ILT2 are significantly decreased; 2) the activating HLA-G14bp+ polymorphism is more frequently observed and is correlated with the decrease of ILT2-expressing cells; 3) the CD56(bright) and CD56(dim) NK subsets are increased; 4) IFNγ and TNF production is reduced; and 5) perforin- and granzymes-releasing NK cells are increased even in unstimulated conditions and could not be upregulated by mitogenic stimulation. DISCUSSION: Results herein reinforce the hypothesis that ASD relatives present traits similar to, but not as severe as the defining features of ASD (Autism endophenotype) and identify a role for NK cells impairment in generating the inflammatory milieu that is observed in ASD.

Information and communication technologies-based interventions for children with autism spectrum conditions: a systematic review of randomized control trials from a positive technology perspective. Front Psychiatry;2023;14:1212522.
Information and communication technologies (ICTs) have become more widely used in the past years to help people with autism spectrum conditions (ASC). Serious games embedded into computers or tablets, as well as social robots, are the most employed ICT-related tools that are appealing to and appropriate for autistic children. The goal of ICT applications is to enhance behavioral abnormalities associated with ASC while also creating an interactive link between one person and one computer. Comparatively, to human-based therapy, ICT tools aid to inspire autistic children by providing predictability and regularity of tasks. Regaining social skills is the primary behavioral goal for which ICT tools have been designed and implemented. In the past several years, many studies have been created to show how effective it is at improving targeted behaviors. However, only a small number of researchers have used an RCT approach to evaluate its effectiveness. In this systematic review, we only included RCT studies where ICT technologies were used to help children with ASC in improving their social skills. Only 14 RCT studies satisfied the criteria and 12 described significant improvements, showing how the use of technology in educational contexts produced better improvement in developing several social skill facets with respect to the traditional face-to-face approach. Some studies used interventions and outcome measures focused on the core ASC symptoms, but many others addressed neurocognitive functions directly, like social cognition or emotional regulation, while other more general functions such as language or adaptive behaviors. We propose a classification based on processes and outcome measures to foster future research in this specific area of research. The behavioral intervention mediated by technological tools such as computer-based, tablet, and social robotics, undoubtedly provides a comfortable environment that promotes constant learning for people with ASC. Evidence provided in this review highlights the translational potential of this field of study in primary care practice and educational settings.

Thurman W, Heitkemper E, Hutson T, Preston A, Hecht J. « The System Tends to Scoop You Up and Spit You Out and They’re Done With You »: The Intersection of Intellectual/Developmental Disability and Homelessness From the Perspectives of Service Providers. Qual Health Res;2023 (Aug 7):10497323231186880.
People with intellectual and developmental disabilities (IDD) experience elevated risk for poor health and social outcomes in adulthood and are at risk for experiencing homelessness and housing instability. Although the exact prevalence of IDD among homeless populations is unknown, a small body of literature related to the intersection of IDD and homelessness suggests differential health needs and service use patterns, with a need for targeted health and social services. In this study, we explore the perceptions and experiences of 18 homeless or disability service providers about (a) their clients at the intersection of IDD and homelessness and (b) their role and the services provided at the intersection of IDD and homelessness. Participants struggled to provide appropriate, accessible services for this population, owing to lack of training and awareness of specific needs, fragmented systems, and inadequately funded healthcare and housing support. Our findings also reveal that clients at this intersection have high contact with public systems, which places them at risk for losing their right to self-determination. Recommendations center on systems transformation to facilitate the ability of providers to collaborate and to make data-driven decisions to deliver person-centered care.

BACKGROUND: Transcranial magnetic stimulation (TMS) has been introduced into the intervention of autism spectrum disorders (ASD) as a possible new therapeutic option for modifying pathological neuroplasticity. However, the stimulating protocols of rTMS for ASD have not been approved unanimously, which affects the clinical popularization and application of rTMS. In addition, there is little research on the improvement of social processing of autistic children by rTMS. METHODS: We explored the clinical efficacy of rTMS and improvement of face processing with the protocol of left high-frequency and right low-frequency on bilateral dorsolateral prefrontal cortex (DLPFC), with a sample of 45 ASD participants aged 2-18. RESULTS: Our results showed that both the score on the Childhood Autism Rating Scale (CARS) and the fixations on the eyes of the human faces improved by two-session rTMS intervention, except for the percentage of eyes fixation. The mediation analysis indicated the item of « Adaptation to Change » of CARS mediated dominantly the improvement of eye-gaze behavior of ASD participants by rTMS. CONCLUSION: Our study revealed the mechanism of rTMS in improving the eye-gaze behavior of the autism population, deepened the understanding of the function of rTMS in treating autistic social disorders, and provided a reference for combined treatment for ASD.

Empathy deficits, callous-unemotional traits and structural underpinnings in autism spectrum disorder and conduct disorder youth. Autism Res;2023 (Aug 7)
Distinct empathy deficits are often described in patients with conduct disorder (CD) and autism spectrum disorder (ASD) yet their neural underpinnings and the influence of comorbid Callous-Unemotional (CU) traits are unclear. This study compares the cognitive (CE) and affective empathy (AE) abilities of youth with CD and ASD, their potential neuroanatomical correlates, and the influence of CU traits on empathy. Adolescents and parents/caregivers completed empathy questionnaires (N = 148 adolescents, mean age = 15.16 years) and T1 weighted images were obtained from a subsample (N = 130). Group differences in empathy and the influence of CU traits were investigated using Bayesian analyses and Voxel-Based Morphometry with Threshold-Free Cluster Enhancement focusing on regions involved in AE (insula, amygdala, inferior frontal gyrus and cingulate cortex) and CE processes (ventromedial prefrontal cortex, temporoparietal junction, superior temporal gyrus, and precuneus). The ASD group showed lower parent-reported AE and CE scores and lower self-reported CE scores while the CD group showed lower parent-reported CE scores than controls. When accounting for the influence of CU traits no AE deficits in ASD and CE deficits in CD were found, but CE deficits in ASD remained. Across all participants, CU traits were negatively associated with gray matter volumes in anterior cingulate which extends into the mid cingulate, ventromedial prefrontal cortex, and precuneus. Thus, although co-occurring CU traits have been linked to global empathy deficits in reports and underlying brain structures, its influence on empathy aspects might be disorder-specific. Investigating the subdimensions of empathy may therefore help to identify disorder-specific empathy deficits.

32. Togher K, Jay S. Disclosing an autism diagnosis: A social identity approach. Autism Res;2023 (Aug 7)
Autistic people face a difficult dilemma around whether or not to disclose their diagnosis because autism is a stigmatized social group. The central aim of this study was to examine if a social identity approach could be useful in understanding the factors that predict the likelihood of autistic adults disclosing their autism diagnosis in social settings, in the workplace, in educational settings and in the family. The social identity approach predicts that autistic people may cope with this dilemma by using an individualistic strategy to distance from their autistic social identity. Alternatively, they may embrace their autistic social identity and use a collective strategy to resist stigma and advocate for autism. We present a survey based cross-sectional study (n = 175) with autistic adults living in Ireland. Participants completed a series of measures; autism social identification, stigma consciousness, and individualistic and collective strategy use to assess disclosing in the four settings. The overall models in each of the four regressions were significant. Autism social identification positively predicted disclosure in social, workplace and educational settings, while stigma consciousness negatively predicted disclosure in the family and in the workplace. Interestingly, over and above these predictors individualistic strategy use negatively predicted disclosure in each of the four settings, while collective strategy positively predicted disclosure in social, educational and family settings. Our novel social identity approach was useful for explaining autistic adult’s strategies to cope with the complex disclosure dilemma. Strengths, limitations, and directions for future research are discussed.

Objective: To examine the funding priorities of the National Institute of Mental Health (NIMH) since 2016 to assess whether NIMH was continuing to prioritize basic research at the expense of clinical research. Methods: Six psychiatric disorders (schizophrenia, bipolar disorder, depression, anxiety disorders, eating disorders, autism) were assessed using 2 publicly available data sources (ClinicalTrials.gov and the National Institutes of Health Research, Condition, and Disease Categorization [RCDC]) to determine the degree of NIMH support for drug trials and research on these disorders in general since 2016. Results: From 2017 through 2022, ClinicalTrials.gov lists just 1 drug trial each for schizophrenia and bipolar disorder. The RCDC database for 2016 through 2021 shows that NIMH support for research projects on schizophrenia and bipolar disorder decreased by 22% and 20%, respectively. During that time, Congress increased the budget of NIMH by 40%. Conclusions: NIMH has continued to prioritize basic research over clinical trials, resulting in a steep decline in funding for possible treatments for the most serious and costly psychiatric diseases.

34. Wang Q, Li X, Gong X, Yin T, Liu Q, Yi L, Liu J. Autistic children’s visual sensitivity to face movement. Dev Psychopathol;2023 (Aug 7):1-10.
There is a pressing need for studies of large sample sizes and variable age ranges to delineate the mechanism underlying reduced visual attention to biological motion in autism. Here we focused on the basic movement of the eyes or mouth in guiding attention. The stimuli face blinked continuously or moved the mouth silently. In a large sample (145 autistic and 132 non-autistic participants) ranging from 3 to 17 years old, we assessed whether autistic participants showed reduced visual attention to basic movement of the eyes or mouth using a free-viewing eye-tracking task. We found that, like non-autistic participants, autistic participants increased their eye-looking time when viewing the blinking face and increased mouth-looking time when viewing the mouth-moving face. Furthermore, these effects were stable across ages, suggesting the presence of a developmentally stable attentional capture by basic face movements in both groups. We also found that autistic participants looked less at basic face movement than non-autistic participants. Our results suggest that autistic children and adolescents could modulate their visual attention to the basic face movements, but their modulation effect is weaker than non-autistic participants. These results further our understanding of the mechanism underlying visual attention-to-face movement in autistic people.
