OBJECTIVES

This study aimed to describe the demographic profile, intervention sessions, goal attainment scaling (GAS), and health-related quality of life (HRQOL) of autistic children receiving speech and language therapy (SLT) in a higher educational institution in the Philippines.

Deidentified data from 18 autistic children aged 4–16 years (mean=8.2; SD=2.9) who received SLT for two months were analyzed. Their demographic profile, intervention sessions, GAS scores, and generic HRQOL scores were documented.

Most participants were school-age children (n=12; 66%) and were boys (n=14; 78%). After two months, the GAS scores of 11 participants (61%) increased by 1–2 points, whereas the scores of the remaining participants decreased (n=6; 33%) or did not change (n=1; 6%). Their mean generic HRQOL scores before and after SLT were 65.6 (SD=15.2) and 61.2 (SD=17.4), respectively.

While the GAS scores increased for most participants, their generic HRQOL scores did not show clinically significant changes after two months of SLT. This can be attributed to the few therapy sessions and short follow-up period. The findings highlight the need to provide long-term support to SLT services of autistic children in the Philippines to document more desirable quality of life outcomes.

Background: The COVID-19 pandemic has affected the well-being of children with Autism Spectrum Disorder (ASD) and their families. The core deficits of the condition and increased parental stress during this time made them more vulnerable. Objectives: This study aims to explore how the pandemic has affected these families by identifying their needs and capabilities in order to provide support. Methods: A total of 227 parents of children with ASD completed an online survey consisting of items on sociodemographic, family needs, and coping strategies. Descriptive statistics were used and t-test and ANOVA/Kruskal Wallis were used to determine the relationship between parent and child factors with needs and coping. Results: Needs for Information, Community Services, and Finances are the top categories while the greatest identified need during this pandemic was for financial assistance. Religiosity, Problem-Solving, and Cognitive Reappraisal were the widely used coping strategies by the parents. Fathers, younger children, daughters with ASD, and having more than one child with ASD showed significant association with needs. Parents with primary and tertiary education were associated with use of the cognitive reappraisal strategy and those with jobs were associated with substance use. Conclusion Families of children with ASD have multiple needs during this pandemic, from autism-specific information and services, to more generic concerns such as financial assistance. Despite these challenges, these families have positive strategies in place to facilitate coping mechanisms.

Brain size abnormality is correlated with an increased frequency of autism spectrum disorder (ASD) in offspring. Genetic analysis indicates that heterozygous mutations of the WD repeat domain 62 (WDR62) are associated with ASD. However, biological evidence is still lacking. Our study showed that Wdr62 knockout (KO) led to reduced brain size with impaired learning and memory, as well as ASD-like behaviors in mice. Interestingly, Wdr62 Nex-cKO mice (depletion of WDR62 in differentiated neurons) had a largely normal brain size but with aberrant social interactions and repetitive behaviors. WDR62 regulated dendritic spinogenesis and excitatory synaptic transmission in cortical pyramidal neurons. Finally, we revealed that retinoic acid gavages significantly alleviated ASD-like behaviors in mice with WDR62 haploinsufficiency, probably by complementing the expression of ASD and synapse-related genes. Our findings provide a new perspective on the relationship between the microcephaly gene WDR62 and ASD etiology that will benefit clinical diagnosis and intervention of ASD.

Autism spectrum disorder (ASD) is a highly heritable neurodevelopmental disorder characterized by deficits in social interactions and repetitive behaviors. Although hundreds of ASD risk genes, implicated in synaptic formation and transcriptional regulation, have been identified through human genetic studies, the East Asian ASD cohorts are still under-represented in genome-wide genetic studies. Here, we applied whole-exome sequencing to 369 ASD trios including probands and unaffected parents of Chinese origin. Using a joint-calling analytical pipeline based on GATK toolkits, we identified numerous de novo mutations including 55 high-impact variants and 165 moderate-impact variants, as well as de novo copy number variations containing known ASD-related genes. Importantly, combined with single-cell sequencing data from the developing human brain, we found that the expression of genes with de novo mutations was specifically enriched in the pre-, post-central gyrus (PRC, PC) and banks of the superior temporal (BST) regions in the human brain. By further analyzing the brain imaging data with ASD and healthy controls, we found that the gray volume of the right BST in ASD patients was significantly decreased compared to healthy controls, suggesting the potential structural deficits associated with ASD. Finally, we found a decrease in the seed-based functional connectivity between BST/PC/PRC and sensory areas, the insula, as well as the frontal lobes in ASD patients. This work indicated that combinatorial analysis with genome-wide screening, single-cell sequencing, and brain imaging data reveal the brain regions contributing to the etiology of ASD.

To study of premature/early death of autistic patients from the perspective of life course can help families, medical institutions and policy makers better deal with the adverse effects of autism. Several studies have shown that autistic patients have a high risk of death, however, the results are still inconsistent. To assess the risk of mortality among the autistic patients, we undertook a comprehensive search of MEDLINE, Web of Science and EMBASE databases. This paper reviewed the studies on the negative disease outcomes of autism spectrum disorders, including the risk of death, causes of death and several research hotspots in this field. Strict inclusion/exclusion criteria were used. Information was extracted from selected papers, tabulated and synthesized. In the study, 15 studies were included, with a total of 216 045 individuals. The main outcome was all-cause mortality in association with autism and the secondary outcome was cause-specific mortality. The results showed that all-cause mortality was higher for the autistic patients (RR=2.32, 95%CI: 1.98-2.72, I²=87.1%, P < 0.001). Risk ratio showed a greater inequality for female than male (male: RR=2.00, 95%CI: 1.57-2.55, I²=93.2%, P < 0.001; female: RR=4.66, 95%CI: 3.30-6.58, I²=92.0%, P < 0.001). Compared with the unnatural death, the risk of natural death was higher (RR=3.44, 95%CI: 1.27-9.26, I²=80.2%, P=0.025). As autism had many comorbidities, which would bring more health risks and natural deaths possibilities. There were some structural differences in unnatural death. Accidental injury death and suicide were two kinds of causes. Lacking social skills would weaken the ability to ask for help when encountering injuries. This paper put forward some suggestions for futures. First, to well study the comorbidity can reduce the risk of death from a medical point of view. Second, the scientists and policymakers should pay attention to the social environment and provide a safer environment for the autistic patients. Third, for women and for adolescents without cognitive impairment, due to their high risk of suicide, the society should provide them with more supportive social networks and improve their life satisfaction. Fourth, it is necessary to balance the rehabilitation resources in various regions in China and provide more high-quality lifelong rehabilitation monitoring and care services.

Increased intestinal barrier permeability, leaky gut, has been reported in patients with autism. However, its contribution to the development of autism has not been determined. We selected dextran sulfate sodium (DSS) to disrupt and metformin to repair the intestinal barrier in BTBR T⁺tf/J autistic mice to test this hypothesis. DSS treatment resulted in a decreased affinity for social proximity; however, autistic behaviors in mice were improved after the administration of metformin. We found an increased affinity for social proximity/social memory and decreased repetitive and anxiety-related behaviors. The concentration of lipopolysaccharides in blood decreased after the administration of metformin. The expression levels of the key molecules in the toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88)-nuclear factor kappa B (NF-κB) pathway and their downstream inflammatory cytokines in the cerebral cortex were both repressed. Thus, "leaky gut" could be a trigger for the development of autism via activation of the lipopolysaccharide-mediated TLR4-MyD88-NF-κB pathway.

OBJECTIVE: To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism (CA), aiming to provide decision-making basis for clinical diagnosis and treatment. METHODS: The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed, EMbase, Cochrane Library, SinoMed, CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th, 2022. PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and AMSTAR 2 (a measurement tool to assess systematic reviews 2) was used to evaluate the methodological quality, bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence. RESULTS: A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low, and there was a serious lack in the aspects of program and registration, search, other analysis and funding. The main problems in methodology included not making prespecified protocol, incomplete retrieval strategy, not providing a list of excluded literatures, and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6 conclusions were valid, 2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low, and the main factors leading to the downgrade were limitations, followed by inconsistency, imprecision and publication bias. CONCLUSION Acupuncture and moxibustion has a certain effect for CA, but the quality of reporting, methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.

OBJECTIVE: To explore the genetic basis for a child with Neurodevelopmental disorder with or without autistic features and/or structural brain abnormalities (NEDASB). METHODS: A child with NEDASB who presented at the Third Affiliated Hospital of Zhengzhou University in July 2021 was selected as the subject. Peripheral blood samples of the child and her parents were collected and subjected to high-throughput sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The child was found to harbor a heterozygous c.820_828delinsCTTCA (p.Thr274Leufs*121) variant of the NOVA2 gene, for which both of her parents were of wild type. The variant was predicted as pathogenic based on the guidelines from the American College of Medical Genetics and Genomics. CONCLUSION The heterozygous c.820_828delinsCTTCA (p.Thr274Leufs*121) variant of the NOVA2 gene probably underlay the disease in this child. Above finding has enriched the spectrum of NOVA2 gene variants and provided a basis for genetic counseling and prenatal diagnosis for this family.

OBJECTIVE: Anxiety is one of the most common symptoms associated with autistic spectrum disorder. The essential oil of Cananga odorata (Lam.) Hook. f. & Thomson, usually known as ylang-ylang oil (YYO), is often used in aromatherapy as a mood-regulating agent, sedative, or hypotensive agent. In the present study, the effects and mechanisms of YYO in alleviating anxiety, social and cognitive behaviors in autism-like rats were investigated. METHODS: The prenatal valproic acid (VPA) model was used to induce autism-like behaviors in offspring rats. The effectiveness of prenatal sodium valproate treatment (600 mg/kg) on offspring was shown by postnatal growth observation, and negative geotaxis, olfactory discrimination and Morris water maze (MWM) tests. Then three treatment groups were formed with varying exposure to atomized YYO to explore the effects of YYO on the anxiety, social and cognitive behaviors of the autistic-like offspring through the elevated plus-maze test, three-chamber social test, and MWM test. Finally, the monoamine neurotransmitters, including serotonin, dopamine and their metabolites, in the hippocampus and prefrontal cortex (PFC) of the rats were measured using a high-performance liquid chromatography. RESULTS: Offspring of VPA exposure rats showed autism-like behaviors. In the VPA offspring, medium-dose YYO exposure significantly elevated the time and entries into the open arms in the elevated plus-maze test, while low-dose YYO exposure significantly enhanced the social interaction time with the stranger rat in session 1 of the three-chamber social test. VPA offspring treated with YYO exposure used less time to reach the platform in the navigation test of the MWM test. YYO exposure significantly elevated the metabolism of serotonin and dopamine in the PFC of VPA offspring. CONCLUSION YYO exposure showed the effects in alleviating anxiety and improving cognitive and social abilities in the offspring of VPA exposure rats. The role of YYO was related to the regulation of the metabolism of serotonin and dopamine. Please cite this article as: Zhang N, Wang ST, Yao L.
