Adaptive behaviors and related factors in children and adolescents with autism spectrum disorder: Report from ELENA cohort.

There are strong individual differences in adaptive behaviors (AB) in autism spectrum disorder (ASD) with conflicting results in literature about specific patterns and related factors. The present study aims to describe AB and identify related factors in terms of clinical and socio-familial characteristics in 875 children and adolescents with ASD in the multiregional ELENA cohort in France. Results showed that AB in children and adolescents with ASD were lower than in typically developing subjects, regardless of age group. AB were associated with clinical (gender, age at diagnosis, IQ, ASD severity, psychiatric comorbidities, motor and language skills, challenging behaviors), interventional (school attendance, special interventions) and familial characteristics (age, educational and socio-economic status of parents, household status, number of siblings). There is a need of interventions focusing on improvement of AB, tailored to children's characteristics.

Screen time and associated risks in children and adolescents with autism spectrum disorders during a discrete COVID-19 lockdown period.

Background: The COVID-19 pandemic may affect the screen time of children and adolescents with Autism Spectrum Disorders (ASD). This study aimed to examine the screen time of children and adolescents with ASD during a discrete lockdown period in France and identify risk factors for excessive screen time. Methods: The study sample consisted of 249 ASD subjects, 3-17 years of age, enrolled in the ELENA cohort. Information about the screen time was collected using the COVID-19 questionnaire specially created for this study. The clinical, socio-demographic and familial characteristics were collected from the last ELENA follow-up visit. Results: More than one third of subjects exceeded recommended levels of screen time and almost half of parents reported that their child spent more time using screen since COVID-19 pandemic beginning. Excessive screen time was significantly related to age with higher screen time in adolescents. Risk factors for excessive screen time were high withdrawn behaviors and low socioeconomic status for children, and older age and male gender for adolescents. Conclusion: These results imply to adapt the recommendations already formulated in general population concerning the good use of screens in youth with ASD. Specific recommendations and suitable guidance are needed to help children and adolescents with ASD and their parents implement the more optimal use of screen time activities for educational, therapeutic and social goals. Trial registration number: NCT02625116.

Factors associated with efficacy of botulinum toxin a injections in primary axillary hyperhidrosis: A retrospective study of ninety patients.

Primary focal hyperhidrosis (PFH) is a frequent condition which can seriously affect the quality of life. Intradermal injections of botulinum toxin A (BTA) is a safe temporary treatment. The objective was to assess the factors associated with the efficacy of the axillary injections of abobotulinumtoxinA in PFH. Among a cohort of 236 patients followed for axillary injections of BTA between 2001 and 2020 for severe PFH, we included patients treated with 150 units per armpit of abobotulinumtoxinA with a minimum follow-up of three years. We described the characteristics of the patients and then searched for association between variables (sex, age, multifocal PFH and duration of efficacy of the first injection [<6 or ≥6 months]) and the number of injections received in three years, counted at the second injection date, by univariate and multivariate logistic regression. Ninety patients were included (62 women, median age of 29 years and 12.2% of multifocal PFH). The median duration of efficacy of the first injection was six months (interquartile range 3-9). The duration of efficacy of the first injection ≥6 months was significantly associated with less injections during the 3-year follow-up in univariate (odds ratio [OR]: -1.18 [95% confidence interval (CI): -1.80 to -0.55]; p < 0.01) and multivariate (OR: -1.16 [95% CI: -1.79 to -0.53]; p < 0.01) logistic regression. There was no significant difference with female sex, age, or multifocal PFH. A duration of efficacy of the first injection greater than six months seems to indicate a better response profile to BTA.

Impact of containment and mitigation measures on children and youth with ASD during the COVID-19 pandemic: Report from the ELENA cohort.

BACKGROUND: Containment, involving separation and restriction of movement of people due to the COVID-19 pandemic, and mitigation, also referred to as lockdown, involving closure of schools, universities and public venues, has had a profound impact on people's lives globally. The study focuses on the effects of containment and mitigation measures, on the behavior of children and youth (CaY) with Autism Spectrum Disorders (ASD). The study primary aim was to examine the impact of these urgent measures on the behaviors, communication, sleep, and nutritional status of the CaY. A secondary aim was to explore risk and protective factors on behavior change including sociodemographic variables, living conditions, ASD symptom severity and continuity of interventions. METHODS: The study sample consisted of 239 ASD subjects, 2-21 years of age, enrolled in the ELENA cohort in France at Stage 3 confinement and mitigation measures announced on March 16, 2020. A parent informant completed the COVID-19 questionnaire. RESULTS: Of the domains examined, challenging behaviors, communicative skills and sleep had the greatest impact; in terms of risk and protective factors, subject age, ASD severity, single parenthood, daily living skills, and intervention continuity were most likely to impact behaviors; living conditions were not linked to behavior change. CONCLUSIONS: The findings highlight the topography of behavioral change in CaY with ASD following institution of containment and mitigation measures during the COVID-19 pandemic and help identify risk and protective factors to help better address needs and tailor interventions in the future.

WISC-V Profiles and Their Correlates in Children with Autism Spectrum Disorder without Intellectual Developmental Disorder: Report from the ELENA Cohort.

The intellectual functioning of people with autism spectrum disorder (ASD) without intellectual developmental disorder (IDD) has not been widely studied. However, marked heterogeneity in assessment measures, samples, and results has been an obstacle for the generalization of findings. We aimed to (a) describe WISC-V intellectual functioning in a sample of children with autism spectrum disorder without intellectual developmental disorder, (b) identify WISC-V profiles, and (c) explore whether WISC-V intellectual functioning is related to ASD symptom severity and adaptive skills. Our sample consisted of 121 children from 6 to 16 years of age with ascertained ASD without an intellectual developmental disorder (IDD). The intellectual functioning of the participants was within the average range. Intra-individual analysis showed that children with ASD performed better on visual than auditory working-memory tasks. Moreover, the intellectual functioning of the participants correlated negatively with ASD symptom severity but positively with adaptive communication skills. Overall, we identified six intellectual profiles according to verbal and reasoning skills. These findings highlight the relevance of WISC-V assessment for children with ASD without an IDD to individualize intervention, especially remediation. LAY SUMMARY: This study examined WISC-V intellectual functioning in 121 children with autism spectrum disorder (ASD) without an intellectual developmental disorder (IDD). We found their intellectual functioning to be within the average, as was that of their peers with typical development (TD), and their verbal and reasoning skills were the most discriminant. In addition, the better their intellectual functioning was, the better their adaptive communication skills and the less severe their ASD symptoms. These findings highlight the relevance of WISC-V assessment in ASD to individualize early psychological remediation.
