Introduction: Alteration of human gut microbiota is described in a number of neuro-developmental and cognitive disorders including autistic spectrum disorder (ASD). Along with the changes in the gut microbiota, children with ASD are also reported to have changes in urinary organic acid spectra implying these metabolites as potential biomarkers for gastrointestinal dysbiosis.Aim: Identify urinary metabolites that would indicate specific changes in the gut microbiota and could be useful as biomarkers.Methods: The study group consisted of 44 children with ASD. Urinary organic acids spectra and composition of gut microbiota were analysed.Results: Any significant deviation in quantified metabolites compared to the reference values were not confirmed. The main variations were detected in concentration of p-cresol and 3-(3-hydroxyphenyl)-3-hydroxypropionic acid (HPHPA), but we cannot confirm the presence of HPHPA in urine as a biomarker for Clostridium sp. overgrowth in the gut. The acquired results indicate higher relative abundance of Firmicutes phylum alone may be attributed to increased concentration of p-cresol in urine. Decreased Bacteroidetes/Firmicutes ratio was found in the group with the presence of HPHPA in urine.Conclusions: Metabolites of human urine can be used as biomarkers for alterations of gut microbiota with caution, guided treatment should be administrated only based on gut microbiota analysis results or in combination with urinary organic acid results, but not solely based on organic acid biomarkers.

Children with Autism Spectrum Disorder (ASD) often have deficits in motor skills, especially balance. This article presents a meta-analytic review of 15 intervention studies that aimed to improve balance in children and adolescents with ASD. Across these studies, there were 195 participants with ASD for whom pre-intervention and post-intervention balance scores were available. We measured the standardized mean difference (Hedges’ g) between their pre-intervention and post-intervention balance scores and found a large, positive effect from these balance interventions (standardized mean difference-1.82 (95% CI [1.34, 2.29]). Various balance intervention procedures were shown to be very efficacious for children and adolescents with ASD. Clearly, balance is a motor skill that is very susceptible to intervention efforts. We also provided recommendations to researchers regarding what information to include when conducting intervention studies.

Social communication and interaction deficits are a diagnostic criteria of autism and integral to practitioner and researcher conceptualization. Culture is an influential factor in expectations for, and demonstration of, social communication and interaction skills, but there is limited research published in autism journals on this topic. This paucity of autism research examining cultural factors related to social communication and interaction may contribute to known identification disparities for racial and ethnic populations minoritized by systemic factors and research bias. We call for increased commitment from researchers to recruit racially and ethnically minoritized participants, prioritize investigating cultural expectations and perceptions of social communication and interaction, and evaluate measures related to social communication for cultural and linguistic responsivity. LAY SUMMARY: A diagnosis of autism requires the presence of deficits in social communication and interaction. Examples of these behaviors and skills include holding a back-and-forth conversation, the use of nonverbal communicative behaviors (e.g., gestures), and developing and maintaining social relationships. Culture influences the expectations for, and presentation of, these behaviors. However, research on this topic is lacking. Conducting more research related to culture and social communication could help reduce the disparities in autism identification across racially and ethnically minoritized populations.

Otology & neurotology : official publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology. 2022; 43(3): 313-9.

OBJECTIVE: To review outcomes of cochlear implantation (CI) in children diagnosed with autism spectrum disorder (ASD). STUDY DESIGN: Retrospective case review and parent survey. SETTING: Tertiary care children’s hospital. PATIENTS: Thirty children with ASD who underwent CI between 1991 and 2018. Mean age at CI = 3.5 years (0.8-11.8), mean age at diagnosis of ASD = 5.1 years (2.0-15.0) (22/30 diagnosed after CI), mean follow-up = 10.5 years (1.4-21.6). Parents of 7 children returned a survey. INTERVENTION: Unilateral or bilateral cochlear implantation. MAIN OUTCOME MEASURES: Speech perception; expressive communication mode; educational placement; social engagement; consistency of CI use; parent survey of child behavior change. RESULTS: Thirty-three percent of all and 45% of the 22 consistent device users developed measurable open-set speech perception by an average of 4.5 years of device use. Educational placement at last follow-up included 13% mainstreamed without interpreter, 50% Special Education programs, 10% therapeutic residential or day programs, 23% total communication programs, and one home schooled. Spoken language alone was used by 31% and spoken plus sign by 14%, with the remainder using sign alone, augmentative communication devices or no mode of communication. By parent report, 86% showed improvement in social engagement compared to pre-CI. Survey results showed the behaviors most frequently ranked as most affected by CI were communication and attention, while awareness of environment had the lowest (most affected) mean ranking. CONCLUSIONS: Findings support a growing body of literature that cochlear implantation has the potential to improve auditory skills, language, and enhance social engagement in some deaf children with autism spectrum disorder.

To investigate the maternal and neonatal risk factors related to pregnancy and birth affecting the occurrence of neurodevelopmental disorders to their children using the medical claim data for the whole population. The study was conducted on all the babies born in Korea from 2005 to 2009 based on data from the National Health Information Database. All birth records were tracked from birth to December 31, 2015. To analyze factors related to the mother, data related to the mother of the newborn were collected. Increased maternal age was found to increase the risk of cerebral palsy (adjusted odds ratio [aOR] = 1.46) and autism spectrum disorder (aOR = 1.48), while lowering the risk of intellectual disability (aOR = 1.83) and speech and language impairment (aOR = 1.41) compared with the reference group aged 25 to 29 years old. The incidence affected by socioeconomic factors varied according to the types of disorders. Among various risk factors, prematurity or low birth weight, problems associated with amniotic fluid or amniotic membrane, preeclampsia or eclampsia, and cesarean section affect the incidence of neurodevelopmental disorders. To reduce the incidence or severity of neurodevelopmental disorders, a better understanding of the risk factors of neurodevelopmental disorders is important. The results of this study can be used as basic data to help such understanding.

BACKGROUND: Autism is reportedly the most severe neuropsychiatric disorder affecting children. Autistic subjects can be characterized by impairments in social interactive behavior along with restricted interests and quite frequently, are seen exhibiting repetitive behavior patterns in stereotyped manner. The inability to perform routine tasks can widely impact the oral health and also, the constant care and sense of helplessness might drastically affect quality of life. AIM: The aim of the study was to assess the oral health status and perceptions regarding an autistic child’s oral health among parents. MATERIALS AND METHODS: Parental perception regarding the quality of life among the afflicted autistic children was done using a self-assessment questionnaire that included eight questions which were replied to in an affirmation or negative answer. 300 parents of autism affected children formed the study participants. Recorded responses were evaluated and percentage of each response was derived. Oral health status was measured by determination of dental caries prevalence and OHI-S index using chair light illumination, mouth mirror, diagnostic probe and a standard WHO periodontal probe. For statistical analysis, the calculations were performed by using the paired t test. Statistical significance, which was fixed at P < 0.05, which is statistically significant. RESULTS: Approximately 18.33% of parents showed were aware that oral health can influence general health; 15% did have exhibit awareness. 15% of parents did not consider that primary teeth were important; 59.1% visited any dentist only when suffering from pain; 5% went for an annual dental examination; 15% and 24.6% parents visited dental practitioners at intervals of 3 and 6 months, respectively. 30%, 25% and 51.66% parents considered obtaining consultation and getting treatment from pediatric dentist; general dentist and general physician. 41.6% parents had taken their children for restorations. 52% reported constant stress whereas 48% reported with constant distressed emotions. No significant difference was determined between the parameters. 75% of autistic children suffered from dental caries whereas oral hygiene scores demonstrated high mean value of 4. CONCLUSION: Autism is a severely distressing condition wherein oral health along with general physical health is affected. Since parents are directly involved in upbringing of these individuals, they also subsequently show a reduction in quality of life.

Gastrointestinal (GI) problems and microbiota alterations have been frequently reported in autism spectrum disorders (ASD). In addition, abnormal perinatal trace metal levels have been found in ASD. Accordingly, mice exposed to prenatal zinc deficiency display features of ASD-like behavior. Here, we model GI development using 3D intestinal organoids grown under zinc-restricted conditions. We found significant morphological alterations. Using proteomic approaches, we identified biological processes affected by zinc deficiency that regulate barrier permeability and pro-inflammatory pathways. We confirmed our results in vivo through proteomics studies and investigating GI development in zinc-deficient mice. These show altered GI physiology and pro-inflammatory signaling, resulting in chronic systemic and neuroinflammation, and gut microbiota composition similar to that reported in human ASD cases. Thus, low zinc status during development is sufficient to compromise intestinal barrier integrity and activate pro-inflammatory signaling, resulting in changes in microbiota composition that may aggravate inflammation, altogether mimicking the co-morbidities frequently observed in ASD.

IMPORTANCE: Recent studies have reported conflicting findings regarding a potential association between analgesia used during labor and autism spectrum disorder in the offspring. OBJECTIVE: To evaluate whether neuraxial labor analgesia increases the risk of autism spectrum disorder in the offspring. DESIGN, SETTING, AND PARTICIPANTS: This cohort study included mother-child dyads who underwent vaginal delivery and were exposed to neuraxial labor analgesia. Delivery data were collected from the Medicaid Analytic eXtract (2005-2014) for mothers with public insurance and the IBM Health MarketScan Research Database (2005-2015) for mothers with private insurance. Data analysis was conducted from January to October 2021. EXPOSURES: Presence of a procedure code indicating neuraxial labor analgesia. MAIN OUTCOMES AND MEASURES: Children with autism spectrum disorder, identified using a validated algorithm (positive predictive value: 94% [95% CI, 83%-99%]). Cumulative incidence curves stratified by exposure were assessed using Kaplan-Meier analyses. Hazard ratios were estimated through Cox proportional hazards regression, using propensity-score fine stratification for confounding control. Estimates from both insurance cohorts were combined through fixed-effects meta-analysis. Subsequently, results from these analyses were combined with existing published studies. RESULTS: The cohort of mother-child dyads with public insurance consisted of 910 696 deliveries (mean [SD] maternal age, 24.3 [5.7] years; 286 025 [31.4%] Black mothers; 374 282 [41.1%] White mothers), with 484 752 (53.2%) being exposed to neuraxial labor analgesia. The cohort of mother-child dyads with private insurance included 696 883 deliveries (mean [SD] maternal age, 31.0 [4.5] years; race and ethnicity data not available), with 513 347 (73.7%) being exposed. Cumulative incidence of autism spectrum disorder by 10 years of age was 1.93% (95% CI, 1.73%-2.13%) among children in the exposed group vs 1.64% (95% CI, 1.51%-1.76%) among children in the unexposed group in the publicly insured cohort. Respective numbers were 1.33% (95% CI, 1.19%-1.46%) and 1.19% (95% CI, 0.99%-1.38%) in the privately insured cohort. Adjusting for potential confounders and pooling across both cohorts resulted in a hazard ratio of 1.08 (95% CI, 1.02-1.15). Results were consistent when additionally adjusting for empirically identified variables through high-dimensional propensity score analyses (pooled hazard ratio, 1.07; 95% CI, 1.00-1.14) or expanding the cohorts to include cesarean deliveries and assisted vaginal deliveries (pooled hazard ratio, 1.07; 95% CI, 1.03-1.12). Meta-analysis of this study and recently published observational studies yielded similar findings with a pooled hazard ratio of 1.10 (95% CI, 1.06-1.13). CONCLUSIONS AND RELEVANCE: Although a small increase in risk cannot be ruled out, the combined evidence from observational studies does not support the notion that neuraxial labor analgesia is associated with an increased risk of autism spectrum disorder.

YUAN Qing’s clinical experience in treating autism spectrum disorder using Tiaoshen (regulating the spirit) acupuncture is summarized. YUAN Qing believes that the basic pathogenesis of children with autism spectrum disorder is due to the impairment of brain essence and heart mind. Thus regulating the spirit, especially adjusting brain essence and heart mind is essential during clinical treatment. The main acupoints on the head (brain tri-points, four-spirit points, spirit setting points, mental tri-points, spirit waking-up points and foot mental points) are used to adjust brain essence, and hand mental tri-points (Shenmen[HT 7], Neiguan[PC 6] and Laogong[PC 8]) are used for adjusting heart mind, and emphasizing the importance of the spirit of the doctor and the children’s parents.
