Recognizing that social functioning and mental health are linked to social participation and employment outcomes, this pilot study examined the preliminary outcomes of an eight-session, work-related social skills training program designed for young adults with high-functioning autism (HFASD). Results indicate statistically significant improvements in social cognition, social function, and social confidence. Furthermore, participants (n = 26) reported statistically significant reductions in anxiety, and a trend toward lessening depressive symptoms. These results suggest that: (1) social skills training is suitable for individuals with HFASD and clinically-significant levels of anxiety and/or depression, and (2) bolstered social functioning may have broader, cyclical impacts on social confidence, psychological wellness, and social and vocational participation in this population.

Variability of neural signaling is an important index of healthy brain functioning, as is signal complexity, which relates to information processing capacity. Alterations in variability and complexity may underlie certain brain dysfunctions. Here, resting-state fMRI was used to examine variability and complexity in children and adolescents with and without autism spectrum disorder (ASD). Variability was measured using the mean square successive difference (MSSD) of the time series, and complexity was assessed using sample entropy. A categorical approach was implemented to determine if the brain measures differed between diagnostic groups (ASD and controls). A dimensional approach was used to examine the continuum of relationships between each brain measure and behavioral severity, age, IQ, and the global efficiency (GE) of each participant’s structural connectome, which reflects the structural capacity for information processing. Using the categorical approach, no significant group differences were found for neither MSSD nor entropy. The dimensional approach revealed significant positive correlations between each brain measure, GE, and age. Negative correlations were observed between each brain measure and the severity of ASD behaviors across all participants. These results reveal the nature of variability and complexity of BOLD signals in children and adolescents with and without ASD.

3. Falk D. {{Non-complicit: Revisiting Hans Asperger’s Career in Nazi-era Vienna}}. {J Autism Dev Disord}. 2019.

Recent allegations that pediatrician Hans Asperger legitimized Nazi policies, including forced sterilization and child euthanasia, are refuted with newly translated and chronologically-ordered information that takes into account Hitler’s deceptive ‘halt’ to the T4 euthanasia program in 1941. It is highly unlikely that Asperger was aware of the T4 program when he referred Herta Schreiber to Am Spiegelgrund or when he mentioned that institution 4 months later on the medical chart of another (unrelated) girl, Elisabeth Schreiber. Asperger campaigned vigorously from 1938 to 1943 to have his specialization, Curative Education, take priority in the diagnosis and treatment of disabled children over other fields that promoted Nazi racial hygiene policies. He neither disparaged his patients nor was he sexist. By 1938, he had identified the essentials of Asperger syndrome and described an unnamed boy whom he later profiled (as Ernst K.) in 1944. Rather than doing ‘thin’ research, Asperger made discoveries that were prescient, and some of his activities conformed to definitions of « individual resistance. »

Previous studies on skill acquisition have taught targets in stimulus sets composed of different numbers of stimuli. Although the rationale for selection of a stimulus set size is not clear, the number of target stimuli trained within a set is a treatment decision for which there is limited empirical support. The current investigation compared the efficiency of tact training in 4 stimulus set sizes, each of which included 12 stimuli grouped into (a) 4 sets of 3 stimuli, (b) 3 sets of 4 stimuli, (c) 2 sets of 6 stimuli, and (d) 1 set of 12 stimuli. Results of all 4 participants with autism spectrum disorder show tact training with larger (i.e., 6 and 12) stimulus set sizes was more efficient than training with smaller (i.e., 3 and 4) stimulus set sizes.

BACKGROUND: The purpose of this article is to describe an interventional project in a University Hospital. It explains the adjustments that were made to provide good care for patients with intellectual and developmental disabilities in an acute care setting in Western Switzerland. It is not the exposition of the results of a formalised research or study. Rather, this article relates the success story of a project initiated by a small group of passionate people on their free time, that eventually entered in the 2020 strategic planning of the largest hospital of Switzerland. Switzerland does not have a national policy regarding health needs for patients with intellectual and developmental disabilities. Health care professionals are not trained to identify and meet the specific health needs of this population and little is taught about intellectual and developmental disabilities during undergraduate studies. METHOD: The Disability Project was conducted between 2012 and 2017 in Geneva University Hospital, as follows: Firstly, over sixty working group sessions took place to identify the specific health needs of people with intellectual and developmental disabilities, to identify the barriers to providing equity of care and to prioritize reasonable adjustments. The four following barriers emerged from these meetings: 1. Lack of awareness of healthcare professionals on specific health issues for patients with intellectual and developmental disabilities, which resulted in a poor healthcare coordination and reduced quality of care. 2. Communication and information transmission issues between hospital staff, families and supported residential accommodations. 3. Lack of training or insufficient training of healthcare professionals and hospital staff on intellectual and developmental disabilities. 4. Inaccessibility of the hospital facilities and buildings for patients with disabilities Secondly, arising from these priorities, interventions were developed. FINDINGS: The interventions were eventually applied throughout the hospital. Recommendations and reasonable adjustments were made to provide accessibility and equity of care for patients with intellectual and developmental disabilities. CONCLUSION: The Disability Project has achieved many reasonable adjustments in an acute care setting to provide good care and satisfaction for this population and their families.

Dysregulated protein synthesis is a major underlying cause of many neurodevelopmental diseases including fragile X syndrome. In order to capture subtle but biologically significant differences in translation in these disorders, a robust technique is required. One powerful tool to study translational control is ribosome profiling, which is based on deep sequencing of mRNA fragments protected from ribonuclease (RNase) digestion by ribosomes. However, this approach has been mainly applied to rapidly dividing cells where translation is active and large amounts of starting material are readily available. The application of ribosome profiling to low-input brain tissue where translation is modest and gene expression changes between genotypes are expected to be small has not been carefully evaluated. Using hippocampal tissue from wide type and fragile X mental retardation 1 (Fmr1) knockout mice, we show that variable RNase digestion can lead to significant sample batch effects. We also establish GC content and ribosome footprint length as quality control metrics for RNase digestion. We performed RNase titration experiments for low-input samples to identify optimal conditions for this critical step that is often improperly conducted. Our data reveal that optimal RNase digestion is essential to ensure high quality and reproducibility of ribosome profiling for low-input brain tissue.

AIM: To improve the oral health of children and teenagers with autism spectrum disorder (ASD) by using an iPad((R))-based training programme. METHODS: Fifty-two children and teenagers with ASD (aged 3-19 years) educated in schools or in care centres participated in this cohort study and followed for 8 months. A training programme for teaching toothbrushing behaviours was proposed to the educational staff. Quotation grids enabled assessment of the programme’s efficacy. RESULTS: Showed an improvement in toothbrushing. The children’s autonomy increased and oral care was more easily implemented when steps were taken by the caregivers. Wilcoxon analysis showed significant improvement in each variable related to toothbrushing. CONCLUSIONS: The iPad((R)) is an attractive and easy device for people with ASD to use. Its use in a training programme for teaching toothbrushing behaviours was efficient.

8. Luyster RJ, Bick J, Westerlund A, Nelson CA, 3rd. {{Testing the effects of expression, intensity and age on emotional face processing in ASD}}. {Neuropsychologia}. 2019; 126: 128-37.

Individuals with autism spectrum disorder (ASD) commonly show global deficits in the processing of facial emotion, including impairments in emotion recognition and slowed processing of emotional faces. Growing evidence has suggested that these challenges may increase with age, perhaps due to minimal improvement with age in individuals with ASD. In the present study, we explored the role of age, emotion type and emotion intensity in face processing for individuals with and without ASD. Twelve- and 18-22- year-old children with and without ASD participated. No significant diagnostic group differences were observed on behavioral measures of emotion processing for younger versus older individuals with and without ASD. However, there were significant group differences in neural responses to emotional faces. Relative to TD, at 12 years of age and during adulthood, individuals with ASD showed slower N170 to emotional faces. While the TD groups’ P1 latency was significantly shorter in adults when compared to 12 year olds, there was no significant age-related difference in P1 latency among individuals with ASD. Findings point to potential differences in the maturation of cortical networks that support visual processing (whether of faces or stimuli more broadly), among individuals with and without ASD between late childhood and adulthood. Finally, associations between ERP amplitudes and behavioral responses on emotion processing tasks suggest possible neural markers for emotional and behavioral deficits among individuals with ASD.

9. Malaia E, Cockerham D, Rublein K. {{Visual integration of fear and anger emotional cues by children on the autism spectrum and neurotypical peers: An EEG study}}. {Neuropsychologia}. 2019; 126: 138-46.

Communication deficits in children with autism spectrum disorders (ASD) are often related to inefficient interpretation of emotional cues, which are conveyed visually through both facial expressions and body language. The present study examined ASD behavioral and ERP responses to emotional expressions of anger and fear, as conveyed by the face and body. Behavioral results showed significantly faster response times for the ASD than for the typically developing (TD) group when processing fear, but not anger, in isolated face expressions, isolated body expressions, and in the integration of the two. In addition, EEG data for the N170 and P1 indicated processing differences between fear and anger stimuli only in TD group, suggesting that individuals with ASD may not be distinguishing between emotional expressions. These results suggest that ASD children may employ a different neural mechanism for visual emotion recognition than their TD peers, possibly relying on inferential processing.

Autism Spectrum Disorders (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are two increasingly prevalent neurodevelopmental disorders. This rise may be associated with a higher dietary intake of n-6 polyunsaturated fatty acids (PUFAs) and lower of n-3 PUFAs. Docosahexaenoic acid (DHA), a key nutritional n-3 PUFA, is crucial for an optimal offspring’s neurodevelopment through the last trimester of pregnancy. Recently, lower DHA levels have been reported in children with ASD and ADHD. The present review summarizes the main research achievements concerning the effect of DHA in children neurodevelopment, in order to elicit its role in the prevention and mitigation of ASD and ADHD. As main finding, a low DHA supply seems to negatively affect childhood neurodevelopment in specific conditions and increase the risk and the severity of ASD or ADHD. Higher DHA status at birth was associated with better childhood neurodevelopmental, but controversial results found in prenatal supplementation raised the hypothesis that the benefits of DHA may be influenced by other factors as socio-economic background and life-style. In conclusion, an optimal DHA provision through maternal diet or breastfeed may promote some neuronal protection in specific offspring’s populations, suggesting that DHA may act as a modifiable risk factor for ASD and ADHD.

AIM: To determine the level of evidence on the effectiveness of health coaching for parents of children with disabilities. METHOD: A systematic review approach, comprised of a comprehensive, librarian-guided literature search; transparent study selection and data extraction; quality assessment; and synthesis of sufficiently similar data (per population, intervention nature, and overall level of evidence for each outcome using standard definitions) was undertaken. RESULTS: Twenty-eight studies (13 randomized clinical trials) were included. Three health coaching approaches were identified: child-targeted (most commonly applied), parent-targeted, and a mixed approach. Overall, there is an insufficient-to-limited level of evidence regarding the effectiveness of these approaches. INTERPRETATION: High-quality clinical trials using the parent-targeted coaching approach are warranted. WHAT THIS PAPER ADDS: Health coaching parents of children with disabilities is an emergent practice. Child-targeted, parent-targeted, or mixed health coaching approaches exist. The child-targeted health coaching approach is currently most applied. Parents of children with autism spectrum disorder are the most common recipients.

Little is known about care needs of young adults with Fragile X Syndrome (FXS). Patient-driven information is needed to improve understanding and support of young adults with FXS. A qualitative study was performed in 5 young adult patients (aged 18-30), and 33 parents of young adults. Concerns and care needs were categorized using the International Classification of Functioning, Disability, and Health. Results indicated concerns on 14 domains for males, and 13 domains for females, including physical, psychological and socio-economical issues. In both groups parents reported high stress levels and a lack of knowledge of FXS in adult care providers. This study revealed concerns on various domains, requiring gender-specific, multidisciplinary transitional care and adult follow-up for patients with FXS.

Vitamin D deficiency has been increasing concurrently with prevalence of autism spectrum disorders (ASD), and emerging evidence suggests vitamin D is involved in brain development. Most prior studies of ASD examined vitamin D levels in children already diagnosed, but a few examined levels during perinatal development, the more likely susceptibility period. Therefore, we examined newborn vitamin D levels in a case-control study conducted among births in 2000-2003 in southern California. Children with ASD (N = 563) or intellectual disability (ID) (N = 190) were identified from the Department of Developmental Services and compared to population controls (N = 436) identified from birth certificates. 25-hydroxyvitamin D (25(OH)D) was measured in archived newborn dried blood spots by a sensitive assay and corrected to sera equivalents. We categorized 25(OH) D levels as deficient (<50 nmol/L), insufficient (50-74 nmol/L), and sufficient (>/=75 nmol/L), and also examined continuous levels, using logistic regression. The adjusted odds ratios (AOR) and 95% confidence intervals for ASD were 0.96 (0.64-1.4) for 25(OH)D deficiency (14% of newborns) and 1.2 (0.86-1.6) for insufficiency (26% of newborns). The AORs for continuous 25(OH)D (per 25 nmol/L) were 1.0 (0.91-1.09) for ASD and 1.14 (1.0-1.30) for ID. Thus, in this relatively large study of measured newborn vitamin D levels, our results do not support the hypothesis of lower 25(OH)D being associated with higher risk of ASD (or ID), although we observed suggestion of interactions with sex and race/ethnicity. 25(OH)D levels were relatively high (median 84 nmol/L in controls), so results may differ in populations with higher prevalence of low vitamin D levels. Autism Res 2019. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We studied whether vitamin D levels measured at birth were related to whether a child later developed autism (or low IQ). Our results did not show that children with autism, or low IQ, overall had lower vitamin D levels at birth than children without autism. Vitamin D levels were fairly high, on average, in these children born in Southern California.

14. Woodcock KA, Cheung C, Gonzalez Marx D, Mandy W. {{Social Decision Making in Autistic Adolescents: The Role of Theory of Mind, Executive Functioning and Emotion Regulation}}. {J Autism Dev Disord}. 2019.

Social decision making is often challenging for autistic individuals. Twenty autistic adolescents made decisions in the socially interactive context of a one-shot ultimatum game, and performance was compared to a large matched typical reference sample. Theory of mind, executive functioning and emotion regulation were measured via direct assessments, self- and parent report. Relative to the reference sample, autistic adolescents proposed fewer fair offers, and this was associated with poorer theory of mind. Autistic adolescents responded similarly to the reference sample when making decisions about offers proposed to them, however they did not appear to down regulate their negative emotion in response to unfair treatment in the same way. Atypical processes may underpin even apparently typical decisions made by autistic adolescents.
