BACKGROUND : Autism spectrum disorders [ASD] is a lifelong disability mainly affecting the development, communication, social interaction and behavior of an individual. Cell transplantation is emerging as a potential therapeutic strategy for ASD. Our previously published proof of concept study showed beneficial effects of cell transplantation in ASD. This study shows effect of cell transplantation in a larger sample size of ASD patients. METHODS : 254 patients diagnosed with ASD on DSM V criteria were enrolled in this open label non-randomized study. The intervention included intrathecal transplantation of autologous bone marrow mononuclear cells and neurorehabilitation. On mean follow up of 7.50 months, percentage analysis was performed on all symptomatic changes. Changes in outcome measures, Indian Scale for Assessment of Autism [ISAA] and Childhood Autism Rating Scale [CARS], were analyzed statistically using Wilcoxon Signed-Rank Test. Comparative analysis of Positron Emission Tomography [PET CT] scan brain, performed before and 6 months after intervention, was done in 86 patients to monitor the outcome at cellular level. Change in the standardized uptake values was statistically evaluated using T-Test [P≤0.05]. RESULTS : Improvements were observed in eye contact, attention and concentration, hyperactivity, sitting tolerance, social interaction, stereotypical behavior, aggressiveness, communication, speech, command following and self-stimulatory behavior. Statistically significant improvement was observed in scores of ISAA and CARS after intervention. A significantly better outcome of the intervention was found in patients at younger age and with shorter duration of disease [<5 years from time of diagnosis]. 86 patients who underwent a repeat PET CT scan showed improved brain metabolism after intervention in areas which correlated to the symptomatic changes. No major procedure related adverse events were recorded. However, 5 patients, with history of seizure and abnormal EEG, had an episode of seizure which was managed using medications. Outcome of intervention in these patients was not affected by seizures as improvements were observed in them. CONCLUSION : The results of this study indicate that autologous bone marrow mononuclear cells in combination with neurorehabilitation are a safe and effective treatment modality for ASD. It improves the quality of life of patients and helps them to integrate in mainstream lifestyle.

2. Tan C, Frewer V, Cox G, Williams K, Ure A. Prevalence and Age of Onset of Regression in Children with Autism Spectrum Disorder : A Systematic Review and Meta-analytical Update. Autism Res ;2021 (Jan 24)

A systematic review published in 2013 reported 32% of children on the autism spectrum experience skill loss, known as autistic regression. However, the frequency varied depending on definition and measures used to capture skills. Retrospective parent report and prospective observation indicate loss of language and/or social skills, with motor skills typically unaffected. Our aim was to update the prevalence and age of onset of autistic regression through a meta-analysis of the literature to understand if there have been changes to the reported onset and prevalence since 2010. A systematic literature search was conducted using Medline, Embase, PsycINFO, and the Cochrane Library databases and included studies published from 2010 onward. Risk of bias assessment was performed on included studies. A random effects model was used to calculate the pooled prevalence and age of onset of autistic regression. Ninety-seven studies were included in the systematic review, of which 75 studies involving 33,014 participants had sufficient data for meta-analytic syntheses. The pooled proportion of autistic regression was 30% (95% confidence interval [CI] : 27-32%) but heterogeneity was high (I(2) = 96.91) and did not reduce with sensitivity or subgroup analyses based on study design or clinical differences, respectively. Prevalence varied according to risk of bias (low : 27%) and definition of regression (language : 20%, language/social : 40%, mixed : 30%, and unspecified : 27%). Weighted average age of onset was 19.8 months. Findings from this meta-analysis highlight the importance of developing a standardized definition of autistic regression, and tools to measure this at multiple time points during early childhood development. LAY SUMMARY : About a third of children with Autism Spectrum Disorder experience loss of skills, which is also known as autistic regression. This paper provides an update of the rate of autistic regression in children and the age when they first experience loss of skills, based on current studies. The findings from this review contribute to our understanding of the onset patterns of autistic regression. Unfortunately, studies are not sufficiently similar, making it difficult to provide clear answers on the exact timing or type of regression seen in different children.

4. Ward J, Ren Z, Qiu J. Autistic Traits in the Neurotypical Chinese Population : A Chinese Version of Glasgow Sensory Questionnaire and a Cross-Cultural Difference in Attention-to-Detail. J Autism Dev Disord ;2021 (Jan 25)

The aim of this study was to assess cross-cultural differences in autistic traits relating to sensory sensitivity/attention-to-detail versus socio-communicative problems in a Chinese sample. A measure of atypical sensory sensitivity (Glasgow Sensory Questionnaire, GSQ) was translated into Chinese and compared against another measure of autistic traits (Chinese version of Autism Quotient, AQ). A second Chinese sample was administered English-language versions. We show that the translated GSQ has : good internal reliability ; a similar profile of item responses to the English version ; and a significant correlation with the AQ. Secondly we report an unexpected, but replicable, finding amongst the Chinese. Specifically, attention-to-detail was negatively correlated with socio-communicative difficulties (whereas in Western samples it is the reverse).

5. Hartley C, Harrison N, Shaw JJ. Does Autism Affect Children’s Identification of Ownership and Defence of Ownership Rights ?. J Autism Dev Disord ;2021 (Jan 25)

This study investigated how autism spectrum disorder (ASD) impacts children’s ability to identify ownership from linguistic cues (proper nouns vs. possessive pronouns) and their awareness of ownership rights. In comparison to typically developing (TD) children matched on receptive language (M age equivalents : 53-56 months), children with ASD were less accurate at tracking owner-object relationships based on possessive pronouns and were less accurate at identifying the property of third parties. We also found that children with ASD were less likely to defend their own and others’ ownership rights. We hypothesise that these results may be attributed to differences in representing the self and propose that ASD may be characterised by reduced concern for ownership and associated concepts.

Heightened attention towards negative information is characteristic of depression. Evidence is emerging for a negative attentional bias in Autism spectrum disorder (ASD), perhaps driven by the high comorbidity between ASD and depression. We investigated whether ASD is characterised by a negative attentional bias and whether this can be explained by comorbid (sub) clinical depression. Participants (n = 116) with current (CD) or remitted depression (RD) and/or ASD, and 64 controls viewed positively and negatively valenced (non-)social pictures. Groups were compared on three components of visual attention using linear mixed models. Both CD individuals with and without ASD, but not remitted depressed and never-depressed ASD individuals showed a negative bias, suggesting that negative attentional bias might be a depressive state-specific marker for depression in ASD.

7. Vivanti G, Messinger DS. Theories of Autism and Autism Treatment from the DSM III Through the Present and Beyond : Impact on Research and Practice. J Autism Dev Disord ;2021 (Jan 25)

The purely descriptive definition of autism introduced by the DSM III in 1980 marked a departure from previous DSM editions, which mixed phenomenological descriptions with psychoanalytic theories of etiology. This provided a blank slate upon which a variety of novel theories emerged to conceptualize autism and its treatment in the following four decades. In this article we examine the contribution of these different theoretical orientations with a focus on their impact on research and practice, areas of overlap and conflict between current theories, and their relevance in the context of the evolving landscape of scientific knowledge and societal views of autism.

8. Yu L, Wang S. Aberrant auditory system and its developmental implications for autism. Sci China Life Sci ;2021 (Jan 22)

Most infants who are later diagnosed with autism show delayed speech and language and/or atypical language profile. There is a large body of research on abnormal speech and language in children with autism. However, auditory development has been relatively under-investigated in autism research, despite its inextricable relationship with language development and despite researchers’ ability to detect abnormalities in brain development and behavior in early infancy. In this review, we synthesize research on auditory processing in the prenatal period through infancy and childhood in typically developing children, children at high risk for autism, and children diagnosed with autism. We conclude that there are clear neurobiological and behavioral links between abnormal auditory development and the deficits in social communication seen in autism. We then offer perspectives on the need for a systematic characterization of early auditory development in autism, and identified questions to be addressed in future research on the development of autism.

Autism spectrum disorder (ASD) is a condition that includes a number of neurodevelopmental mental disorders. Recent genetic/genomic investigations have reported an increased prevalence of copy number variations (CNVs) in individuals with autism. Despite the extensive evidence of a genetic component, the genes involved are not known and the background is heterogeneous among subjects. As such, it is highly likely that multiple events (molecular cascades) are implicated in the development of autism. The aim of this work was to shed some light on the biological background behind this condition. We hypothesized that the heterogeneous alterations found within different individuals may converge into one or more specific biological functions (pathways) linked to the heterogeneous phenotypes commonly observed in subjects with ASD. We analyzed a sample of 107 individuals for CNV alterations and checked the genes located within the altered loci (1366). Then, we characterized the subjects for distinct phenotypes. After creating subsamples based on symptoms, the CNVs related to each specific symptom were used to create distinct networks associated with each phenotype (18 in total in the sample under analysis). These networks were independently clustered and enriched to identify potential common pathways involved in autism and variably combined with the clinical phenotype. The first 10 pathways of the analysis are discussed.

10. Singh NN, Lancioni GE, Medvedev ON, Hwang YS, Myers RE. Real-Time Telehealth Treatment Team Consultation for Self-Injury by Individuals with Autism Spectrum Disorder. Adv Neurodev Disord ;2021 (Jan 19):1-13.

OBJECTIVES : Self-injurious behavior (SIB) refers to any repeated self-directed, non-suicidal, behavior that may cause or has the potential to cause physical harm to the person’s body. Behavioral interventions provide the standard evidence-based treatments for SIB by people with autism spectrum disorder (ASD) and intellectual disabilities (ID). Translating the proven effectiveness of behavioral interventions to treatment of self-injury in community settings by clinicians and caregivers has not been totally successful. The aim of the present study was to advance translational research by providing real-time telehealth consultation to a treatment team at a community-based mental health agency that provided inpatient and outpatient services to individuals with ASD and ID. METHOD : The participants of this single-case experimental study were three adolescents with ASD who had been referred for services because of their increasingly unmanageable SIB both at home and at school. The telehealth consultant provided real-time assistance to the treatment team within a translational model of care in the development and implementation of a behavior support plan and an informal mindfulness-based Soles of the Feet (SoF) program. RESULTS : Both visual and statistical analyses demonstrated reductions in the frequency of SIB for all three adolescents, with overall clinically significant reductions only with the SoF intervention. CONCLUSION : The results of this translational study suggest that telehealth consultation might be a viable technological alternative in situations which preclude face-to-face consultation. Telehealth consultation could be one method of supporting people with behavioral difficulties during pandemics, such as COVID-19.

Volitional modification of brain activity in adolescents with Autism Spectrum Disorder : A Bayesian analysis of Slow Cortical Potential neurofeedback. Neuroimage Clin ;2021 (Jan 9) ;29:102557.

Autism spectrum disorder is (ASD) characterized by a persisting triad of impairments of social interaction, language as well as inflexible, stereotyped and ritualistic behaviors. Increasingly, scientific evidence suggests a neurobiological basis of these emotional, social and cognitive deficits in individuals with ASD. The aim of this randomized controlled brain self-regulation intervention study was to investigate whether the core symptomatology of ASD could be reduced via an electroencephalography (EEG) based brain self-regulation training of Slow Cortical Potentials (SCP). 41 male adolescents with ASD were recruited and allocated to a) an experimental group undergoing 24 sessions of EEG-based brain training (n(1) = 21), or to b) an active control group undergoing conventional treatment (n(2) = 20), that is, clinical counseling during a 3-months intervention period. We employed real-time neurofeedback training recorded from a fronto-central electrode intended to enable participants to volitionally regulate their brain activity. Core autistic symptomatology was measured at six time points during the intervention and analyzed with Bayesian multilevel approach to characterize changes in core symptomatology. Additional Bayesian models were formulated to describe the neural dynamics of the training process as indexed by SCP (time-domain) and power density (PSD, frequency-domain) measures. The analysis revealed a substantial improvement in the core symptomatology of ASD in the experimental group (reduction of 21.38 points on the Social Responsiveness Scale, SD = 5.29), which was slightly superior to that observed in the control group (evidence Ratio = 5.79). Changes in SCP manifested themselves as different trajectories depending on the different feedback conditions and tasks. Further, the model of PSD revealed a continuous decrease in delta power, parallel to an increase in alpha power. Most notably, a non-linear (quadratic) model turned out to be better at predicting the data than a linear model across all analyses. Taken together, our analyses suggest that behavioral and neural processes of change related to neurofeedback training are complex and non-linear. Moreover, they have implications for the design of future trials and training protocols.

Quarantine derived from COVID-19 pandemic has challenged children and adolescents with Autism Spectrum Disorder (ASD) and their families daily life and routines. Because of these children unique needs related to manage uncertainty and overcoming situations, an in-depth approach to how they navigated through quarantine urged to better comprehend their current support needs. Forty-seven families with a child with ASD ranging in age between 2 and 17 years old (M = 7.3, SD = 3.4) from the north of Spain responded to an online developed questionnaire on different aspects of their daily life management of quarantine. Most of the families stressed that their offspring better drove quarantine than expected. Some families reported that youth participated more often in families’ routines and were more communicative with their parents. Families, beyond some difficulties aroused, had more time to qualitatively spend with their children to teach new skills as autonomy or house care related skills. Families also developed new strategies to manage quarantine, such as structuring their days, using visual supports or new technologies for learning or leisure, and found more useful in this effort their family cohesion, online contact with relatives, and having online psychological supports.

Health Service Utilization Patterns Among Medicaid-Insured Adults With Intellectual and Developmental Disabilities : Implications for Access Needs in Outpatient Community-Based Medical Services. J Ambul Care Manage ;2021 (Jan 20)

Limited existing evidence suggests that adults with intellectual and developmental disabilities (IDD) experience substantial disparities in numerous areas of health care, including quality ambulatory care. A multistate cohort of adults with IDD was analyzed for patterns of inpatient admissions and emergency department utilization. Utilization was higher (inpatient [RR = 3.2], emergency department visits [RR = 2.6]) for adults with IDD, particularly for ambulatory care-sensitive conditions (eg, urinary tract [RR = 6.6] and respiratory infections [RRs = 5.5-24.7]), and psychiatric conditions (RRs = 5.8-15). Findings underscore the importance of access to ambulatory care skilled in IDD-related needs to recognize and treat ambulatory care-sensitive conditions and to manage chronic medical and mental health conditions.

Children and adolescents with ASD also have co-occurrence of attention deficit hyperactivity disorder (ADHD) symptoms. ADHD symptoms, especially hyperactivity, greatly increased the severity of autism symptoms. This study concentrated on two widely-used medications : the second generation of antipsychotics (SGAs) and ADHD medication, aiming to conduct a meta-analysis about their effect on hyperactivity, so it would offer some evidence for clinical medication choice. The Medline, Embase, Cochrane Central Register of Controlled Trials and China National Knowledge Infrastructure databases were searched from inception to July 2019 for studies exploring the use of SGAs and ADHD medications in autistic children and adolescents. Double-blind, randomized controlled trials that reported hyperactivity as an outcome were included in the study. A total of thirteen trials with 712 participants were included in our meta-analysis. For SGAs, the standardized mean difference (SMD) of hyperactivity subscale in Aberrant behavior checklist scale or conners rating scales was 0.59, 95% confidence interval (CI) : 0.23-0.96, I2 = 74%, Q = 15.34, P < 0.01. For ADHD medications, SMD was -0.66, with 95% CI : -0.99 to 0.33, I2 = 53%, Q = 15.02, P = 0.04. As for adverse events, in the SGAs group, somnolence had the largest effect size, risk ratio = 5.62, 95% CI : 3.20- 9.87 (I2 = 0%, Q = 2.45, P = 0.65). In ADHD group, the side effect of decreased appetite showed the largest effect size (risk ratio = 2.63, 95% CI = 0.99-7.01, I2 = 65.7%, Q = 11.66, P = 0.02). Both ADHD medications and SGAs were effective in dealing with hyperactivity in children and adolescents with autism but were shown to increase the risk of decreased appetite, somnolence, headache and nausea or vomiting. The clinical use of these medications should carefully weigh the benefits and risks.

BACKGROUND : Catatonia is increasingly recognized as a comorbid psychiatric condition in autism spectrum disorder (ASD), but the overlap of behavioral characteristics between these disorders raises many diagnostic challenges. Moreover, recognizing symptoms in ASD patients with medium-low functioning might be difficult. Literature on this argument is poor, especially for children. Case presentation. We report the case of an ASD patient with low cognitive functioning, who presented a complex symptomatology, characterized by progressive regression with loss of autonomy and involuntary movements that assume "dystonic" features. Organic pathology was excluded, and catatonia, with peculiar dystonic characteristics, was diagnosed. An intervention based on elimination of stressful factors, resumption of routines, and support for parents led to the resolution of catatonic symptoms. CONCLUSIONS : The case describes the presence among the catatonic symptoms in ASD of involuntary "dystonic" movements ; so far, little reported in literature ; it highlights that the catatonia may present with a broad spectrum of motor abnormalities. There is still little evidence for treatment of catatonia and ASD. Our case highlights how it is equally important to take into account triggering factors when implementing a nonpharmacological treatment. So, it represents an example of diagnostic and therapeutic challenges of catatonia in ASD, especially in low functioning forms.

Protocol for Development of the Indian Autism Screening Questionnaire : The Screening Version of the Indian Scale for Assessment of Autism. Indian J Psychol Med ;2020 (Dec) ;42(6 Suppl):S63-S67.

INTRODUCTION : Autism is included as a certifiable disability in the Indian Rights of Persons with Disability Act, 2016. The Indian Scale for Assessment of Autism (ISAA), developed by the Government of India and mandated for certifying disability, is a detailed instrument that needs trained mental health experts and takes time to administer. The current project was planned to develop a simple, easy to use screening tool based on the ISAA to identify possible cases in the community. METHODS : The project is planned in three phases. During the first phase, data collected during the development of the ISAA (N = 433/436 children with autism) will be used to identify questions answered as frequently, mostly, and always. During the second phase, the psychometric properties of the screening tool based on these items will be evaluated among research participants recruited from hospitals and special schools (n = 100). In the third phase, the screening questionnaire will be administered in the community (n = 500). RESULTS : The most frequently answered questions will be selected for inclusion in the proposed screening tool. The number of items in the screening tool will be kept as few as possible, with yes or no responses. DISCUSSION : Indian Autism Screening Questionnaire (IASQ) will be tested as a screening version of ISAA, which can be used by community health workers, teachers, or school counselors. The IASQ will not provide a diagnosis of autism. A positive screening result should be followed by a thorough assessment by a trained specialist. Analyzing the psychometric properties of the test can help ensure cost-effective screening of the community to identify autism.

The autonomic nervous system (ANS) is responsible for the functioning of the heart, bladder, pupils and several other bodily functions. Therefore, when the ANS functions abnormally, individuals can experience a number of physical symptoms, including dizziness, abnormal sweating and digestive difficulties. Currently, it is unclear if autistic adults experience ANS dysfunction. Therefore, in this study, we investigated whether autistic adults report more ANS-related physical symptoms, indicating greater ANS dysfunction, and whether this may be related to autism, or rather anxiety, depression, or stress. The findings suggest that ANS dysfunction, where found in autism, is due to co-occurring stress and anxiety. We therefore propose that treating stress and anxiety may be an effective way to ameliorate ANS-related health problems in autistic adults.

Although participation in communities is a key component of health and well-being, little research has explored community participation among autistic adults. A better understanding of preferences and access to various community activities among autistic adults provides intervention and policy directions in a critical area. This study reports responses from one of the largest groups of autistic adults surveyed to date. Participants reported their valued activities, number of days they participated in each activity during the previous month, and the extent to which they perceived their participation to be sufficient. Grocery shopping was the most common community activity, and most important. A wide range of activities were participated in during the previous month and more than half of the autistic adults reported that most activities were important. Autistic adults with a co-occurring intellectual disability participated in fewer activities and said that fewer activities were important. Sufficiency, or the degree to which an individual felt they participated enough in important activities, was greater for autistic adults with higher incomes and lower for autistic adults who lived independently or had co-occurring psychiatric diagnoses. Breadth of participation, or the number of important types of participation in the past month, was lower for autistic adults residing in supported living facilities and for autistic adults with co-occurring psychiatric diagnoses. Breadth was greater for autistic adults with self-reported service needs. Our study findings offer important information to guide implementation of new federal requirements aimed at promoting greater community participation among individuals covered by Medicaid.

Analysis by age and spectrum severity in a school population. Autism ;2021 (Jan 25):1362361320987724.

This study makes a comparison between the growth status of pre-school and school-age children with autism spectrum disorder and typical development children. Pre-schoolers with autism spectrum disorder were taller than children with typical development. School-age children with autism spectrum disorder were more overweight/obese, had more body fat and a greater waist circumference and waist/height ratio than children with typical development. The presence of autism spectrum disorder and internalizing problems was associated with cardiovascular risk in school-age children.

20. Kuschner ES, Kim M, Bloy L, Dipiero M, Edgar JC, Roberts TPL. MEG-PLAN : a clinical and technical protocol for obtaining magnetoencephalography data in minimally verbal or nonverbal children who have autism spectrum disorder. J Neurodev Disord ;2021 (Jan 23) ;13(1):8.

BACKGROUND : Neuroimaging research on individuals who have autism spectrum disorder (ASD) has historically been limited primarily to those with age-appropriate cognitive and language performance. Children with limited abilities are frequently excluded from such neuroscience research given anticipated barriers like tolerating the loud sounds associated with magnetic resonance imaging and remaining still during data collection. To better understand brain function across the full range of ASD there is a need to (1) include individuals with limited cognitive and language performance in neuroimaging research (non-sedated, awake) and (2) improve data quality across the performance range. The purpose of this study was to develop, implement, and test the feasibility of a clinical/behavioral and technical protocol for obtaining magnetoencephalography (MEG) data. Participants were 38 children with ASD (8-12 years) meeting the study definition of minimally verbal/nonverbal language. MEG data were obtained during a passive pure-tone auditory task. RESULTS : Based on stakeholder feedback, the MEG Protocol for Low-language/cognitive Ability Neuroimaging (MEG-PLAN) was developed, integrating clinical/behavioral and technical components to be implemented by an interdisciplinary team (clinicians, behavior specialists, scientists, and technologists). Using MEG-PLAN, a 74% success rate was achieved for acquiring MEG data, with a 71% success rate for evaluable and analyzable data. Exploratory analyses suggested nonverbal IQ and adaptive skills were related to reaching the point of acquirable data. No differences in group characteristics were observed between those with acquirable versus evaluable/analyzable data. Examination of data quality (evaluable trial count) was acceptable. Moreover, results were reproducible, with high intraclass correlation coefficients for pure-tone auditory latency. CONCLUSIONS : Children who have ASD who are minimally verbal/nonverbal, and often have co-occurring cognitive impairments, can be effectively and comfortably supported to complete an electrophysiological exam that yields valid and reproducible results. MEG-PLAN is a protocol that can be disseminated and implemented across research teams and adapted across technologies and neurodevelopmental disorders to collect electrophysiology and neuroimaging data in previously understudied groups of individuals.

BACKGROUND : The aims of this study were to explore to explore the viewpoints of parents of children with Autism Spectrum Disorders (ASD) and professionals regarding the implementation of screening programs for ASD, to explore the challenges of the implementation of a universal screening program for ASD in Iran from their viewpoints, and, to explore their recommendations to overcome the potential challenges. METHOD : This qualitative study was conducted using an inductive content analysis, between June 2018 and December 2018, in East-Azerbaijan province of Iran. Data was collected through in-depth interviews and focus group discussions. The participants were purposively selected among two groups : representatives of health system and representatives of children with ASD. A sample of 32 parents and 30 professionals were recruited in this study. RESULTS : Totally, 9 main themes and 23 sub-themes were extracted in three main areas including : viewpoints of the participants about universal screening for ASD, challenges in implementation of the universal screening program, and participants’ recommendations about how to overcome the potential challenges. Main challenges in implementation of the universal screening program included : shortages of ASD screening tools, weakness of the health system, lack of coordination among the ASD service providers, and social and ethical issues. CONCLUSION : The parents and the professionals had different viewpoints about the implementation of ASD universal screening program in Iran. According to the professionals, there is not enough rational to implement ASD screening program for all children. However, the parents believed that universal screening program is inevitable, and it should be implemented in primary health centers during the early child-care visits. The results of this study open up unspoken issues that could help in initiating the screening program not only in Iran but also in other low- and middle-income countries as well.

Impact of antipsychotics in children and adolescents with autism spectrum disorder : a systematic review and meta-analysis. Health Qual Life Outcomes ;2021 (Jan 25) ;19(1):33.

BACKGROUND : The net health benefit of using antipsychotics in children and adolescents with ASD is unclear. This review was performed to provide the evidence necessary to inform the Italian national guidelines for the management of ASD. METHODS : We performed a systematic review of randomized controlled trials (RCTs) comparing antipsychotics versus placebo for the treatment of ASD in children and adolescents. For efficacy, acceptability and safety we considered outcomes evaluated by the guideline panel critical and important for decision-making. Continuous outcomes were analyzed by using standardized mean difference (SMD), and dichotomous outcomes by calculating the risk ratio (RR), with their 95% confidence interval (95% CI). Data were analyzed using a random effects model. We used the Cochrane tool to assess risk of bias of included studies. Certainty in the evidence of effects was assessed according to the GRADE approach. RESULTS : We included 21 RCTs with 1,309 participants, comparing antipsychotics to placebo. Antipsychotics were found effective on "restricted and repetitive interests and behaviors" (SMD - 0.21, 95% CI - 0.35 to - 0.07, moderate certainty), "hyperactivity, inattention, oppositional, disruptive behavior" (SMD - 0.67, 95% CI - 0.92 to - 0.42, moderate certainty), "social communication, social interaction" (SMD - 0.38, 95% CI - 0.59 to - 0.16, moderate certainty), "emotional dysregulation/irritability" (SMD - 0.71, 95% CI - 0.98 to - 0.43, low certainty), "global functioning, global improvement" (SMD - 0.64, 95% CI - 0.96 to - 0.33, low certainty), "obsessions, compulsions" (SMD - 0.30, 95% CI - 0.55 to - 0.06, moderate certainty). Antipsychotics were not effective on "self-harm" (SMD - 0.14, 95% CI - 0.58 to 0.30, very low certainty), "anxiety" (SMD - 0.38, 95% CI - 0.82 to 0.07, very low certainty). Antipsychotics were more acceptable in terms of dropout due to any cause (RR 0.61, 95% CI 0.48 to 0.78, moderate certainty), but were less safe in terms of patients experiencing adverse events (RR 1.19, 95% CI 1.07 to 1.32, moderate certainty), and serious adverse events (RR 1.07, 95% CI 0.48 to 2.43, low certainty). CONCLUSIONS : Our systematic review and meta-analysis found antipsychotics for children and adolescents with ASD more efficacious than placebo in reducing stereotypies, hyperactivity, irritability and obsessions, compulsions, and in increasing social communication and global functioning. Antipsychotics were also found to be more acceptable, but less safe than placebo.

23. Langenfeld A, Schema L, Eckerle JK. Genetic developmental disability diagnosed in adulthood : a case report. J Med Case Rep ;2021 (Jan 25) ;15(1):28.

BACKGROUND : Developmental disabilities (DD) are an umbrella term for conditions associated with functional impairments in physical, learning, language, or behavior areas. Intellectual disability (ID) is a type of developmental disability that results in delays in cognitive or intellectual functioning, such as reasoning, learning, and problem-solving, and adaptive behaviors including social and practical life skills. DD can be due to a variety of factors, ranging from environmental exposures to genetic mutations, and studies suggest that up to 40% of DDs may be caused by genetic issues. CASE PRESENTATION : In this case study, we present an 18-year-old internationally adopted female Chinese American patient with a known history of developmental delay, intellectual disability, strabismus, and a congenital heart defect who had not been tested for genetic causes of her delay prior to presentation. When evaluated with chromosomal microarray, the patient demonstrated a deletion on the short arm of chromosome 5, an area associated with Cri-du-chat syndrome. This chromosomal deletion was a likely explanation for her history of developmental delays, intellectual disability, and congenital heart defect, in addition to her history of institutionalization and the trauma of multiple caregiver transitions in early childhood. The patient was referred for further evaluation by a geneticist and genetic counselor. CONCLUSIONS : This case highlights that the underlying cause of developmental delay is often multifactorial, and underscores the importance of a full medical evaluation, including genetic testing, for children with intellectual disability. Using this approach, healthcare professionals can identify potential diagnoses and provide more targeted resources to families.

Individuals with autism spectrum disorder (ASD) show impairments in processing social cues such as facial expressions and gaze direction. Several researchers have proposed that autistic traits form a continuum that may be distributed within the general, typically developed, population. Accordingly, several studies have indicated that typically developed individuals with high levels of self-reported autistic traits have autistic-like performance in a variety of paradigms. Here, we designed a gaze-cueing task to examine whether gaze-triggered orienting is related to the extent of typically developed (TD) individuals’ autistic traits (determined by their AQ test scores) and whether it is modulated by previous eye contact and different facial expressions. At each trial, TD subjects observed faces with or without eye contact. This facial stimulus then gazed toward the left or right side. Finally, a target appeared on the left or right side of the display and reaction time (RT) to the target was measured. RTs were modulated by congruency between gazing directions and target locations, and by prior eye contact in the congruent trials. In addition, individuals with higher AQ scores were slower at detecting the target when the cue was a happy face. Furthermore, faster RTs in congruent trials were associated with one specific autistic trait (attention switching deficits). Together, these results indicate that autistic traits may influence performance in a gaze cueing task.

25. Doreswamy S, Bashir A, Guarecuco JE, Lahori S, Baig A, Narra LR, Patel P, Heindl SE. Effects of Diet, Nutrition, and Exercise in Children With Autism and Autism Spectrum Disorder : A Literature Review. Cureus ;2020 (Dec 22) ;12(12):e12222.

Diet and nutrition play an important and essential role in everyone’s life. It helps build a healthy body and a strong mind. We know that food rich in nutrients can remove toxins from the body, make an excellent immune system, curb hunger, and prevent obesity. Obesity is one of the most concerning, alarming, and fastest-growing pandemics. It affects not only adults but also adolescents and children. The disease’s early-onset calls for prompt attention to control the physical, psychological, financial, and social burden it creates. Children with autism and autism spectrum disorders (ASDs) are commonly affected by eating disorders. Their preference for energy-dense food with low nutrition can alter their metabolism, leading to the accumulation of oxidative radicals, causing them to deteriorate mentally and physically. Although dieting and losing weight are now commonly seen in the general population, it has become hard to bring awareness to children with special needs about diet, nutrition, and obesity. Despite efforts, parents of such children usually cannot help control the eating because tantrums and behavioral problems are common. It is now imperative for doctors and parents to work alongside nutritionists and dieticians to help these children eat healthy to be fit and improve the quality of life.

Grabrucker S, Pagano J, Schweizer J, Urrutia-Ruiz C, Schön M, Thome K, Ehret G, Grabrucker AM, Zhang R, Hengerer B, Bockmann J, Verpelli C, Sala C, Boeckers TM. Activation of the medial preoptic area (MPOA) ameliorates loss of maternal behavior in a Shank2 mouse model for autism. EMBO J ;2021 (Jan 25):e104267.

Impairments in social relationships and awareness are features observed in autism spectrum disorders (ASDs). However, the underlying mechanisms remain poorly understood. Shank2 is a high-confidence ASD candidate gene and localizes primarily to postsynaptic densities (PSDs) of excitatory synapses in the central nervous system (CNS). We show here that loss of Shank2 in mice leads to a lack of social attachment and bonding behavior towards pubs independent of hormonal, cognitive, or sensitive deficits. Shank2(-/-) mice display functional changes in nuclei of the social attachment circuit that were most prominent in the medial preoptic area (MPOA) of the hypothalamus. Selective enhancement of MPOA activity by DREADD technology re-established social bonding behavior in Shank2(-/-) mice, providing evidence that the identified circuit might be crucial for explaining how social deficits in ASD can arise.
