"A win-win for all of us": COVID-19 sheds light on the essentialness of child care as key infrastructure.

Child care centers in the United States allow many parents and caregivers to work in and outside of the home and support the growth and development of children. Child care closures and COVID-19 mitigation measures at the onset of the pandemic heightened the need for and awareness of the role of child care as core infrastructure. The purpose of our study was to examine the perceived role and benefits of child care based on the lived experiences of parents/caregivers and staff navigating child care during the pandemic. We conducted in-depth qualitative interviews with parents/caregivers (n = 20) of children who attended child care and staff (n = 12) who were working at child care programs in Ohio from September to November 2020. Qualitative data were coded and analyzed through the lens of four frameworks (i.e., capabilities, developmental, economics, and mutualism) related to child well-being. Our results highlight the perceived value of child care (a) for fostering capabilities and developmental growth in children; (b) for providing economic benefits for children, parents, and staff of child care programs; and (c) as an essential infrastructure that mutually benefits children, parents, families, staff, and the community. Findings support existing evidence regarding the broader impacts of child care and further investigation into the role of child care. We highlight the potential need for further investments in policies, resources, and supports for child care that reflects its essentialness and generative role.

Challenges in assessing change in autistic adults: scale limitations and discrepancies in reporting in clinical trials.

Autism Spectrum Disorder (ASD) is a developmental disorder marked by deficits in social communication and social interaction, together with restricted and/or repetitive patterns of behaviours, activities or interests. As more adults are being diagnosed with ASD, and more diagnosed children are aging into adulthood, the need for effective treatments and support services for autistic adults is quickly growing. As such, clinical research targeting autistic adults has emerged in recent years. Currently, caregiver ratings are commonly used as outcome measures in child treatment studies, but these scales present challenges when utilised to assess the autistic adult population. In this commentary, we seek to unveil the difficulties and obstacles in assessing change in clinical treatment trials for autistic adults. Specifically, this article uses case examples to explore the limitations of rating scales. Steps for improving the accuracy of ratings, and for developing novel self-rating scales for autistic adults are discussed. It is hoped that in exploring these difficulties in more depth, clinical research with adult ASD populations will continue to improve and that reliable, valid and sensitive outcome measures will be developed to ensure the highest quality treatments emerge.

Eye tracking as an objective measure of hyperphagia in children with Prader-Willi syndrome.

This study examined sensitivity of eye tracking measures to hyperphagia severity in Prader-Willi syndrome (PWS). Gaze data were collected in 57 children with PWS, age 3-11 years, and 47 typically developing peers at two study sites during free visual exploration of complex stimulus arrays that included images of food, animals, and household objects. Analysis of the number and duration of fixations as well as gaze perseverations revealed that food items are not exceptionally salient for children with PWS. Instead, increased attention to food in the context of other high-interest items (e.g., animals) was associated with caregiver reports of more severe hyperphagia and more advanced nutritional phase. The study also provided preliminary evidence of possible genetic subtype and sex differences as well as demonstrated that multiple investigators in a wide range of settings can effectively implement the eye tracking protocol. The results indicate that gaze characteristics derived from eye tracking may be a promising objective marker of hyperphagia in PWS for use in research and clinical trials.

Neurodevelopmental Disorders (ASD and ADHD): DSM-5, ICD-10, and ICD-11.

Neurodevelopmental disorders, specifically autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) have undergone considerable diagnostic evolution in the past decade. In the United States, the current system in place is the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), whereas worldwide, the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) serves as a general medical system. This review will examine the differences in neurodevelopmental disorders between these two systems. First, we will review the important revisions made from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) to the DSM-5, with respect to ASD and ADHD. Next, we will cover the similarities and differences between ASD and ADHD classification in the DSM-5 and the ICD-10, and how these differences may have an effect on neurodevelopmental disorder diagnostics and classification. By examining the changes made for the DSM-5 in 2013, and critiquing the current ICD-10 system, we can help to anticipate and advise on the upcoming ICD-11, due to come online in 2017. Overall, this review serves to highlight the importance of progress towards complementary diagnostic classification systems, keeping in mind the difference in tradition and purpose of the DSM and the ICD, and that these systems are dynamic and changing as more is learned about neurodevelopmental disorders and their underlying etiology. Finally this review will discuss alternative diagnostic approaches, such as the Research Domain Criteria (RDoC) initiative, which links symptom domains to underlying biological and neurological mechanisms. The incorporation of new diagnostic directions could have a great effect on treatment development and insurance coverage for neurodevelopmental disorders worldwide.

Efficacy of a Remote Play-Based Intervention for Children With Prader-Willi Syndrome.

The current study examines the efficacy of an 8-week pretend play intervention targeting social-cognitive abilities in children with Prader-Willi syndrome (PWS), ages 6-9. PWS is a rare disorder associated with various social, emotional, and cognitive challenges linked to pretend play impairments, and for which interventions are sparse. Nineteen children were quasi-randomized to receive the intervention or be part of a waitlist control group. Participants who received the intervention (n = 10) demonstrated significant improvements in various components of pretend play, most notably in organization of play, which may generalize to broader social-cognitive gains. These findings provide evidence of the intervention's efficacy in enhancing pretend play skills and related social-cognitive abilities during this critical period of development for children with PWS.

Intervention Response by Genetic Subtype: PRETEND-Preschool Program for Children with Prader-Willi Syndrome via Remote Parent Training.

Prader-Willi Syndrome (PWS) is a rare neurodevelopmental disorder associated with social cognitive challenges, and pretend play has been demonstrated as a tool to achieve developmental goals. Following previous report on feasibility and acceptability of a remote, play-based parent-training program (Zyga, Russ, & Dimitropoulos, 2018), we now report on preliminary efficacy of this program to enhance pretend play skills and social cognitive skills in preschoolers with PWS. Results across two studies demonstrated efficacy when live-coaching play sessions incorporated children into the intervention. Increases in play skills were observed for children with the mUPD subtype of PWS who underwent intervention, compared with children with mUPD who were waitlisted. Children with DEL subtype were less likely to respond to intervention. Implications for results are discussed.

Believing in Make-Believe: Efficacy of a Pretend Play Intervention for School-Aged Children with High-Functioning Autism Spectrum Disorder.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder marked by socio-emotional deficits, and difficulties with pretend play skills. Play skills are related to processes of adaptive functioning and emotion understanding. The present pilot study implemented an in-person pretend play intervention to school-aged children (ages 6 to 9 years, intervention group = 18, control group = 7) diagnosed with high-functioning ASD (HF-ASD), to increase children's cognitive and affective play skills, and emotional understanding abilities. The intervention consisted of 5 weekly sessions, 15-20 minutes each. The intervention group significantly increased in imagination and cognitive play skills, which generalized to increased skills in emotional understanding. Findings demonstrate the positive impact of a short, easily facilitated, accessible play intervention for school-aged children with HF-ASD.

Show me what happens next: Preliminary efficacy of a remote play-based intervention for children with Prader-Willi syndrome.

Prader-Willi Syndrome (PWS) is characterized by decreased social and emotional functioning. Due to the low base-rate of children with PWS, developing behavioral interventions for individuals with PWS is faced with the challenge of enrolling enough local participants for adequate study of behavioral intervention efficacy. However, these types of studies are greatly needed in PWS and telehealth methodology may be useful in addressing this challenge. This article is a follow-up to a previous feasibility study (Dimitropoulos et al., 2017) and reports on the preliminary efficacy of a telehealth intervention delivered to 15 children, ages 6-12, with PWS. Overall, children demonstrated significantly improved cognitive and affective processes in pretend play and general cognitive flexibility following the 6-week remote intervention. These findings are limited by the lack of control group and small sample size which should be considered when interpreting results. Overall, these preliminary findings point to the potential role pretend play can serve as a means of enacting cognitive and behavioral change via telehealth.

Intranasal oxytocin versus placebo for hyperphagia and repetitive behaviors in children with Prader-Willi Syndrome: A randomized controlled pilot trial.

OBJECTIVE: The effects of intranasal oxytocin and placebo on hyperphagia and repetitive behaviors were compared in children and adolescents with Prader Willi Syndrome (PWS). METHODS: Children and adolescents with PWS were enrolled in an 8-week double-blind placebo-controlled intranasal oxytocin randomized trial. Twenty-three (23) subjects were assigned to oxytocin (N = 11) or placebo (N = 12). Hyperphagia was measured with the Hyperphagia Questionnaire (HQ), and repetitive behavior was measured with Repetitive Behavior Scale- Revised (RBS-R). RESULTS: There were modest significant treatment by-time interactions indicating reduction in hyperphagia and repetitive behaviors across time for placebo but no reduction for oxytocin. Total HQ score showed a greater average reduction of 1.81 points/week for the placebo group vs. oxytocin, with maximum reduction at week 4. There were also greater reductions on HQ-Drive and HQ-Behavior subscales on placebo vs. oxytocin. RBS-R subscales followed similar patterns to the HQ, with a significantly greater reduction in sameness subscale behaviors (average 0.825 points/week) in the placebo group compared to the oxytocin group. Oxytocin was well tolerated, and the only adverse event that was both more common and possibly related to oxytocin vs. placebo was nocturia (n = 1 vs 0). CONCLUSION: Placebo was associated with modest improvement in hyperphagia and repetitive behaviors in childhood PWS whereas intranasal oxytocin was not associated with improvement in these domains. More work is needed to understand the meaning and mechanism of these findings on hyperphagia and repetitive behaviors in PWS.

Randomized crossover feasibility trial of helminthic Trichuris suis ova versus placebo for repetitive behaviors in adult autism spectrum disorder.

Objectives: Inflammatory mechanisms are implicated in the aetiology of autism spectrum disorder (ASD), and use of the immunomodulator Trichuris suis Ova (TSO) is a novel treatment approach. This pilot study determined the effect sizes for TSO versus placebo on repetitive behaviours, irritability and global functioning in adults with ASD.Methods: A 28-week double-blind, randomised two-period crossover study of TSO versus placebo in ten ASD adults, aged 17-35, was completed, with a 4-week washout between each 12-week period at Montefiore Medical Center, Albert Einstein College of Medicine. Subjects with ASD, history of seasonal, medication or food allergies, Y-BOCS ≥6 and IQ ≥70 received 2,500 TSO ova or matching placebo every 2 weeks of each 12-week period.Results: Large effect sizes for improvement in repetitive behaviours (d = 1.0), restricted interests (d = 0.82), rigidity (d = 0.79) and irritability (d = 0.78) were observed after 12 weeks of treatment. No changes were observed in the social-communication domain. Differences between treatment groups did not reach statistical significance. TSO had only minimal, non-serious side effects.Conclusions: This proof-of-concept study demonstrates the feasibility of TSO for the treatment of ASD, including a favourable safety profile, and moderate to large effect sizes for reducing repetitive behaviours and irritability.Clinicaltrials.gov: NCT01040221.

Behavioral phenotype in a child with Prader-Willi syndrome and comorbid 47, XYY.

We report a 12-year-old male with Prader-Willi syndrome (PWS) and 47, XYY syndrome. Genetic work up revealed 47, XYY karyotype. PWS diagnosis was made by polymerase chain reaction methylation and maternal uniparental disomy (mUPD) was determined to be the etiology. Review of distinct behavioral features, possible interplay between the two syndromes and considerations for diagnoses are presented. To our knowledge, this is the first report of behavioral features in PWS with comorbid 47, XYY.

The cost and impact of compulsivity: A research perspective.

Compulsivity is the defining feature of various psychiatric disorders including Obsessive Compulsive Related Disorders (OCRDs), and other compulsive, impulsive, and addictive disorders. These disorders are disabling, chronic conditions with an early onset and high rates of comorbidity, misdiagnoses, and delay in treatment onset. Disorders of compulsivity are responsible for considerable socioeconomic burden to society. We review the costs and impacts of compulsivity. In order to facilitate earlier diagnosis and targeted treatments, we examine the overlapping mechanisms that underlie compulsivity. We reconceptualize psychiatric disorders based on core features of compulsivity, highlight challenges in harmonizing research in children and adults, describe newer research methodologies, and point to future directions that can impact the costs and impact of disorders of compulsivity.

White matter maturation profiles through early childhood predict general cognitive ability.

Infancy and early childhood are periods of rapid brain development, during which brain structure and function mature alongside evolving cognitive ability. An important neurodevelopmental process during this postnatal period is the maturation of the myelinated white matter, which facilitates rapid communication across neural systems and networks. Though prior brain imaging studies in children (4 years of age and above), adolescents, and adults have consistently linked white matter development with cognitive maturation and intelligence, few studies have examined how these processes are related throughout early development (birth to 4 years of age). Here, we show that the profile of white matter myelination across the first 5 years of life is strongly and specifically related to cognitive ability. Using a longitudinal design, coupled with advanced magnetic resonance imaging, we demonstrate that children with above-average ability show differential trajectories of myelin development compared to average and below average ability children, even when controlling for socioeconomic status, gestation, and birth weight. Specifically, higher ability children exhibit slower but more prolonged early development, resulting in overall increased myelin measures by ~3 years of age. These results provide new insight into the early neuroanatomical correlates of cognitive ability, and suggest an early period of prolonged maturation with associated protracted white matter plasticity may result in strengthened neural networks that can better support later development. Further, these results reinforce the necessity of a longitudinal perspective in investigating typical or suspected atypical cognitive maturation.

Characterizing longitudinal white matter development during early childhood.

Post-mortem studies have shown the maturation of the brain's myelinated white matter, crucial for efficient and coordinated brain communication, follows a nonlinear spatio-temporal pattern that corresponds with the onset and refinement of cognitive functions and behaviors. Unfortunately, investigation of myelination in vivo is challenging and, thus, little is known about the normative pattern of myelination, or its association with functional development. Using a novel quantitative magnetic resonance imaging technique sensitive to myelin we examined longitudinal white matter development in 108 typically developing children ranging in age from 2.5 months to 5.5 years. Using nonlinear mixed effects modeling, we provide the first in vivo longitudinal description of myelin water fraction development. Moreover, we show distinct male and female developmental patterns, and demonstrate significant relationships between myelin content and measures of cognitive function. These findings advance a new understanding of healthy brain development and provide a foundation from which to assess atypical development.
