A Novel Group Parenting Intervention for Emotional and Behavioral Difficulties in Young Autistic Children: Autism Spectrum Treatment and Resilience (ASTAR): A Randomized Controlled Trial. Journal of the American Academy of Child and Adolescent Psychiatry. 2021; 60(11): 1404-18.

OBJECTIVE: To examine the feasibility and preliminary efficacy of a group behavioral parenting intervention for emotional and behavioral problems (EBPs) in young autistic children. METHOD: This was a feasibility pilot randomized controlled trial comparing a 12-week group behavioral parenting intervention (Predictive Parenting) to an attention control (Psychoeducation). Parents of 62 autistic children 4 to 8 years of age were randomized to Predictive Parenting (n = 31) or Psychoeducation (n = 31). The primary outcome was a blinded observational measure of child behaviors that challenge. Secondary outcomes were observed child compliance and parenting behaviors; parent- and teacher-reported child EBPs; self-reported parenting practices, stress, self-efficacy, and well-being. Cost-effectiveness was also explored. RESULTS: Recruitment, retention, completion of measures, treatment fidelity, and parental satisfaction were high for both interventions. There was no group difference in primary outcome: mean log of rate 0.18 lower (d, 90% CI = -0.44 to 0.08) in Predictive Parenting. Differences in rates of child compliance (0.44, 90% CI = 0.11 to 0.77), facilitative parenting (0.63, 90% CI = 0.33 to 0.92) and parent-defined target symptom change (-0.59, 90% CI -0.17 to -1.00) favored Predictive Parenting. There were no differences on other measures. Predictive Parenting was more expensive than Psychoeducation, with a low probability of being more cost-effective. CONCLUSION: Feasibility was demonstrated. There was no evidence from this pilot trial that Predictive Parenting resulted in reductions in child EBPs beyond those seen following Psychoeducation; in addition, the effect size was small, and it was more expensive. However, it showed superiority for child compliance and facilitative parenting with moderate effect sizes. Future, definitive studies should evaluate whether augmented or extended intervention would lead to larger improvements.

Összefoglaló. A humán mikrobiom az emberi szervezetben és az emberi testfelszínen élő mikrobaközösségek összessége, amelyek többsége a gyomor-bél rendszerben él. Ezek a mikrobaközösségek számos és sokféle baktériumot tartalmaznak, gombákat, vírusokat, archeákat és protozoonokat. Ez a mikrobiális közösség, vagy mikrobiota, a gazdaszervezetben nagyrészt egymással kölcsönösségi viszonyban tenyészik, és gondoskodik a bélben a tápanyagok anyagcseréjéről, kalibrálja az anyagcsere-működést, tanítja az immunrendszert, fenntartja a közösség integritását, és véd a kórokozók ellen. A majdan megszületendő magzat a megfelelő tápanyagellátását az anyai véráramból kapja, és így az anyai szervezetben a mikrobiota indukálta baktériumkomponensek vagy metabolitok hatékonyan átvihetők a magzatba. Az anyai mikrobiális közösségek – ideértve a praenatalis bélrendszeri, hüvelyi, száj- és bőrmikrobiomot – a terhesség alatt valójában kifejezett változásokon mennek keresztül, amelyek befolyásolhatják az egészség megőrzését, és hozzájárulhatnak a közismert betegségek kialakulásához. A magzat nem steril, és immunológiai szempontból sem naiv, hanem az anya révén környezeti ingerek hatásaitól befolyásolva kölcsönhatásba lép az anyai immunrendszerrel. Számos anyai tényező – beleértve a hormonokat, a citokineket és a mikrobiomot – módosíthatja az intrauterin környezetet, ezáltal befolyásolva a magzati immunrendszer fejlődését. A fokozott stresszben élő anyák csecsemőinél nagyobb az allergia és a gyomor-bél rendszeri rendellenességek aránya. A várandós étrendje is befolyásolja a magzati mikrobiomot a méh közvetítésével. A bélflóránk, vagyis a mikrobiom, a belünkben élő mikrobák összessége és szimbiózisa, amelynek kényes egyensúlya már csecsemőkorban kialakul, és döntően meghatározza az intestinalis barrier és a bélasszociált immunrendszer működését. A probiotikumok szaporodásához szükséges prebiotikummal is befolyásolható a bélflóra. A pre- és a probiotikum kombinációja a szimbiotikum. Az anyatej a patogénekkel szemben protektív hatású, részben azáltal, hogy emeli a Bifidobacterium-számot az újszülött bélflórájában. A dysbiosis a kommenzális, egészséges bélflóra megváltozása. Ennek szerepét feltételezik funkcionális gastrointestinalis kórképekben, egyre több pszichiátriai és neurológiai kórképben is, mint az autizmus-spektrumzavar. Orv Hetil. 2021; 162(19): 731-740. Summary. The human microbiome is the totality of microbe communities living in the human body and on the human body surface, most of which live in the gastrointestinal tract. These microbe communities contain many and varied bacteria, fungi, viruses, archaea and protozoa. This microbial community or microbiota in the host is largely reciprocal and takes care of nutrient metabolism in the gut, calibrates metabolism, teaches the immune system, maintains community integrity, and protects against pathogens. The fetus to be born is adequately supplied with nutrients from the maternal bloodstream, and thus microbial-induced bacterial components or metabolites can be efficiently transferred to the fetus in the maternal body. Maternal microbial communities, including prenatal intestinal, vaginal, oral, and dermal microbiomes, actually undergo pronounced changes during pregnancy that can affect health maintenance and contribute to the development of well-known diseases. The fetus is not sterile or immunologically naïve, but interacts with the maternal immune system through the effects of environmental stimuli through the mother. Many maternal factors, including hormones, cytokines, and the microbiome, can modify the intrauterine environment, thereby affecting the development of the fetal immune system. Infants of mothers under increased stress have higher rates of allergies and gastrointestinal disorders. The diet of the gravida also affects the fetal microbiome through the uterus. Our intestinal flora, or microbiome, is the totality and symbiosis of the microbes living in them, the delicate balance of which is established in infancy and decisively determines the functioning of the intestinal barrier and the intestinal associated immune system. The prebiotic required for the proliferation of probiotics can also affect the intestinal flora. The combination of pre- and probiotic is symbiotic. Breast milk has a protective effect against pathogens, in part by raising the number of Bifidobacteria in the intestinal flora of the newborn. Dysbiosis is a change in the commensal, healthy gut flora. Its role is hypothesized in functional gastrointestinal disorders, as well as in more and more psychiatric and neurological disorders such as the autism spectrum disorder.

The importance of personality traits for the outcome of psychiatric treatment, including treatment for alcohol use disorder (AUD), has been widely acknowledged. Also, research on autism spectrum disorders has evolved in recent years, emphasizing that the behavioral traits within these neuropsychiatric disorders exist on a dimension both within and outside the boundaries of psychopathology. In the present study, the relationship between personality traits associated with autistic functioning and level of alcohol use among patients before and after concluded AUD treatment was investigated. The participants (n = 165, diagnosed with AUD) were part of a longitudinal project on AUD treatment. Data from personality questionnaires (Structured Clinical Interview of Personality Disorders II and Temperament and Character Inventory) were used to assess autistic personality traits (APTs) based on behavior within Wing’s triad, which were related to background and treatment outcome. The chosen APT items illustrated a personality functioning with an emphasis on social interaction and rigidity. Only certain included questions were indicative of still having a problematic drinking pattern 2.5 years after treatment entry, which adhered to phobic, obsessive-compulsive, and schizoid personality traits, as well as rigidity/stubbornness. Albeit with modest influence, the degree of APTs was associated with heavier drinking at treatment entry, and symptoms relating to social interaction and rigidity were associated with still having a problematic drinking pattern 2.5 years after treatment entry. A higher degree of such traits may result in having problems taking advice from others and establishing treatment alliance, important parts of treatment efficacy, making assessment of such traits relevant to clinicians.

Autism spectrum disorder (ASD) diagnoses increased over the last decades, as reviews show comparing prevalence rates reported from different studies. Due to different effects of the disorder, personal support is required and provided by formal and/or informal caregivers in various activities of daily living. With the help of a customized smart home and interior design concept the aim is to enable people with ASD to live a more independent and self-reliant life. Following a participatory research approach, the end users are involved in the context of use and requirements definition, concept development, and later also in the implementation, and evaluation process. The solution shall assist end users in performing activities of daily living. The outcome of the work at hand is a set of modular functionalities (sensors, actuators, interior design solutions) to be integrated in a living environment specifically designed for people with ASD.

The Association of the Medicaid 1915(c) Home and Community-Based Services Waivers with Emergency Department Utilization among Youth with Autism Spectrum Disorder. Journal of autism and developmental disorders. 2022; 52(4): 1587-97.

Using the 2008-2013 Medicaid Analytic eXtract files, this retrospective cohort study was to evaluate the effect of Medicaid home and community-based services (HCBS) waiver programs on emergency department (ED) utilizations among youth with autism spectrum disorder (ASD). Our study showed that the annual ED utilization rates were 13.5% and 18.8% for individuals on autism specific and intellectual and developmental disabilities (IDD) waivers respectively, vs. 28.5% for those without a waiver. Multivariable logistic regression showed that, compared to no waiver, autism specific waivers (adjusted odds ratio: 0.62; 95% Confidence Interval: [0.58-0.66]) and IDD waivers (0.65; [0.64-0.66]) were strongly associated with reduced ED. These findings suggest that HCBS waivers are effective in reducing the incidence of ED visits among youth with ASD.

Intervention Services for Autistic Adults: An ASDEU Study of Autistic Adults, Carers, and Professionals’ Experiences. Journal of autism and developmental disorders. 2022; 52(4): 1623-39.

The Autism Spectrum Disorders in the European Union (ASDEU) survey investigated local services’ use experiences of autistic adults, carers and professionals with interventions for autistic adults. The majority of the 697 participants experienced recommended considerations prior to deciding on intervention and during the intervention plan and implementation. Psychosocial interventions were the most commonly experienced interventions, while pharmacological interventions NOT recommended for core autistic symptoms were reported by fairly large proportions of participants. Family interventions were experienced slightly more commonly by carers than adults or professionals. Less than the 26% of autistic adult responders who had experienced challenging behaviors reported receiving an intervention to change them. These results provide insights for improving gaps in service provision of interventions among autistic adults.

Little research has examined the full-range of participation among adults on the autism spectrum. The current study addresses this knowledge gap by comparing the frequency, importance, breadth, and sufficiency of participation between autistic adults and adults in the general population. Autistic adults participated less, had fewer areas that were important to them, participated in fewer areas that were important to them, and were less satisfied with their participation even after controlling for demographic characteristics. Moreover, this study raises questions about what influences their perceptions about the breadth of activities that are important to them and the degree to which they desire to participate in those areas. Suggestions for future interventions and research are offered.

Variability in Responding to Joint Attention Cues in the First Year is Associated With Autism Outcome. Journal of the American Academy of Child and Adolescent Psychiatry. 2022; 61(3): 413-22.

OBJECTIVE: With development, infants become increasingly responsive to the many attention-sharing cues of adults; however, little work has examined how this ability emerges in typical development or in the context of early autism spectrum disorder (ASD). This study characterized variation in the type of cue needed to elicit a response to joint attention (RJA) using the Dimensional Joint Attention Assessment (DJAA) during naturalistic play. METHOD: We measured the average redundancy of cue type required for infants to follow RJA bids from an experimenter, as well as their response consistency, in 268 infants at high (HR, n = 68) and low (LR, N = 200) familial risk for ASD. Infants were assessed between 8 and 18 months of age and followed up with developmental and clinical assessments at 24 or 36 months. Our sample consisted of LR infants, as well as HR infants who did (HR-ASD) and did not (HR-neg) develop ASD at 24 months. RESULTS: We found that HR and LR infants developed abilities to respond to less redundant (more sophisticated) RJA cues at different rates, and that HR-ASD infants displayed delayed abilities, identifiable as early as 9 months, compared to both HR-neg and LR infants. Interestingly, results suggest that HR-neg infants may exhibit a propensity to respond to less redundant (more sophisticated) RJA cues relative to both HR-ASD and LR infants. CONCLUSION: Using an approach to characterize variable performance of RJA cue-reading abilities, findings from this study enhance our understanding of both typical and ASD-related proficiencies and deficits in RJA development.

The relationship between tendency to attend to detail, sensory sensitivity, and affective response to food cues – A registered report. International journal of psychophysiology : official journal of the International Organization of Psychophysiology. 2021; 166: 50-60.

Understanding the underlying drivers of food choice remains a challenge and has highlighted the need for measures that capture data over and above that offered by self-reporting tools. Consequently, a growing body of research has set out to interpret facial responses to food cues to offer a greater insight into the emotional responses that may drive food acceptance. However, interpreting facial responses is challenging, as there are numerous factors that may influence affective response to foods, including expectation, context, and individual differences. Existing findings suggest there is a link between autistic traits and sensory sensitivities; research highlights further links between sensory sensitivities and eating behaviour, and autistic traits and eating behaviour, with a body of research focusing on the autistic trait attention to detail (ATD). As such, the current study aimed to examine rapid facial activity in response to foods cues while capturing these individual differences present in the general population. This study found no evidence to suggest facial responses to food pictures were linked with attention to detail or hyper-sensitivity. The findings did support a general link between self-reported pleasantness ratings of viewed foods and activity of facial muscles. Post-hoc analyses suggested scoring on the social skills sub-scale of the Autism Quotient (AQ) was associated with levator activity while viewing pictures low in pleasantness. This study offers a greater understanding of variations, at the individual level, which are associated with affective response to foods, and may help to inform the development of tools that set out to predict food acceptance.

BACKGROUND: Intervention during the first years of life for children with autism spectrum disorder (ASD) may have the strongest impact on long-term brain development and functioning. Yet, barriers such as a shortage of trained professionals contribute to significant delays in service. The goal of this proof-of-concept study was to explore strategies that support timely and equitable deployment of ASD-specific interventions. METHODS: This 15-week, randomized proof-of-concept study explored the acceptability of a digital parent mediated intervention online reciprocal imitation training (RIT; a naturalistic developmental behavioral intervention) and compared it to a treatment as usual (TAU) control on parent and child outcomes. Eligible children were between 18 and 60 months, met the cutoff for ASD on the Autism Diagnostic Observation Schedule-2nd Edition and demonstrate significant social imitation deficits. Primary outcomes include the acceptability of RIT (Scale of Treatment Perceptions) and the feasibility of the Online RIT digital intervention (online RIT attributes). Secondary outcomes included parent fidelity (RIT parent fidelity form) and parental self-efficacy (Early Intervention Parenting Self-Efficacy Scale). Exploratory outcome measures included child social communication (Social Communication Checklist), child imitation skills (Unstructured Imitation Assessment), and family quality of life (Beach Center Family Quality of Life Scale). RESULTS: Twenty participants were randomized in a 1:1 fashion. The acceptability and feasibility of RIT and the Online RIT digital intervention were rated highly. Among the secondary outcomes, there were significant group differences in parent fidelity (p < .001) and self-efficacy (p = .029). On exploratory outcomes, there were group differences in child social communication (p = .048). There were no significant group differences in imitation ability (p = .05) or family quality of life (p = .22). LIMITATIONS: There are several limitations with this study, including the small sample size as well as lack of data on enactment and website engagement. This study was not able to address questions related to which variables predict program engagement and treatment response, which will be critical for determining which families may benefit from such a stepped-care delivery model. CONCLUSIONS: Overall, the Online RIT program delivered in a stepped-care format shows strong acceptability and holds promise as an innovative delivery model.

Self-regulated learning versus activity-based intervention to reduce challenging behaviors and enhance school-related function for children with autism spectrum disorders: A randomized controlled trial. Research in developmental disabilities. 2021; 114: 103986.

BACKGROUND: Self-regulated learning is an active learning cognitive approach which helps individuals to be aware of their own ability and environment and control their own learning. AIM: This study examined the therapeutic effects of self-regulated learning on reducing challenging behaviors and enhancing school-related function in children with autism spectrum disorders. METHODS: Forty children (aged 6-12) were randomized into a 12-week Self-Regulated Learning or Activity-Based intervention control group. Three outcome measures, assessing the behavior and school-related function of the children in both groups, were administered before and after the intervention and at one-month follow-up. The results between the two groups were also compared. RESULTS: The Self-Regulated Learning group showed significantly better results in reducing concerning behaviors and enhancing the school-related function than the activity-based group post-intervention and at one-month follow-up. CONCLUSIONS: The Self-Regulated Learning intervention was more effective compared to the Activity-Based intervention with particular benefits for on-going learning and improvements.

12. Weir E, Allison C, Ong KK, Baron-Cohen S. An investigation of the diet, exercise, sleep, BMI, and health outcomes of autistic adults. Molecular autism. 2021; 12(1): 31.

BACKGROUND: Studies of autistic children suggest that restricted eating, reduced physical activity, and sleep disorders are common; however, no studies attempt to broadly describe the diet, exercise, and sleep patterns of autistic adults or consider relationships between lifestyle behaviors and the widely reported increased risks of obesity and chronic conditions. To address this, the authors developed the largest study of lifestyle patterns of autistic adults and assessed their relationships to body mass index, health outcomes, and family history. METHODS: We administered an anonymized, online survey to n = 2386 adults (n = 1183 autistic) aged 16-90 years of age. We employed Fisher’s exact tests and binomial logistic regression to describe diet, exercise, and sleep patterns; mediation of seizure disorders on sleep; body mass index (BMI); relationships of lifestyle factors to BMI, cardiovascular conditions, and diabetic conditions; and sex differences among autistic adults. RESULTS: Autistic adults, and particularly autistic females, exhibit unhealthy diet, exercise, and sleep patterns; they are also more likely to be underweight or obese. Limited sleep duration and high rates of sleep disturbances cannot be accounted for by epilepsy or seizure disorders. Lifestyle factors are positively related to higher risk of cardiovascular conditions among autistic males, even more than family history. LIMITATIONS: Our sample may not be representative of all autistic and non-autistic people, as it primarily comprised individuals who are white, female, have a high school education or higher, and reside in the UK. Our sampling methods may also exclude some individuals on the autism spectrum, and particularly those with moderate to severe intellectual disability. This is a cross-sectional sample that can test for relationships between factors (e.g., lifestyle factors and health outcomes) but cannot assess the direction of these relationships. CONCLUSIONS: Autistic adults are less likely to meet minimal health recommendations for diet, exercise, and sleep-and these unhealthy behaviors may relate to excess risk of cardiovascular conditions. Although the present study can only provide preliminary, correlational evidence, our findings suggest that diet, exercise, and sleep should be considered and further investigated as key targets for reducing the now widely reported and dramatically increased risks of health comorbidity and premature death among autistic individuals compared to others. Physicians should work cooperatively with patients to provide health education and develop individualized strategies for how to better manage challenges with diet, exercise, and sleep.
