Creating an Equitable System of Care for Minoritized Youth and Addressing Systemic and Structural Barriers.

We provide an overview of the systems of care and the barriers faced by minoritized youth. We discuss ways to address barriers by forging alliances, improving communication with cultural humility, and a nonjudgmental approach. We underscore the importance of a holistic evaluation of minoritized children while leveraging their resilience to create a comprehensive and multipronged plan of action.

Brief Report: A Double-Blind, Placebo-Controlled, Crossover, Proof-of-Concept Study of Minocycline in Autism Spectrum Disorder.

Neuroinflammatory mechanisms have been implicated in the pathophysiology of autism spectrum disorder (ASD). Minocycline is a matrix metalloproteinase inhibitor 9 (MMP9) inhibitor tetracycline antibiotic with known anti-inflammatory properties. In preclinical animal models of ASD, minocycline has demonstrated potential positive effects on phenotypes that may have relevance to ASD. We conducted the first placebo-controlled study of minocycline in ASD. This double-blind, placebo-controlled crossover trial employed four week treatment periods with a two week washout period. Twenty-four 12-22 year olds (mean age 17.4 years; range 12.9-22.5 years) with ASD were enrolled. Overall minocycline was well tolerated. No minocycline-associated clinical changes were noted with treatment on any performance or clinician or caregiver completed measures were noted. We hypothesize that either minocycline does not have potential therapeutic effects in ASD or our project was underpowered to define potential subject subgroups who may potentially respond positively to this drug.

Immigrant/Acculturation Experience.

In this article, we provide an overview on how to approach matters of forging a therapeutic alliance, empathetic listening, addressing issues related to obtaining informed consent, and limits of confidentiality, with cultural humility and nonjudgmental curiosity while working with diverse immigrants groups. We also discuss the use of broaching to discuss culturally sensitive topics with immigrant children and families The clinical pearls can be applied to different clinical scenarios and a variety of cross-cultural encounters.

Alzheimer-Like Pattern of Hypometabolism Emerges with Elevated Amyloid-ß Burden in Down Syndrome.

BACKGROUND: The Down syndrome (DS) population is genetically predisposed to amyloid-ß protein precursor overproduction and Alzheimer's disease (AD). OBJECTIVE: The temporal ordering and spatial association between amyloid-ß, glucose metabolism, and gray matter (GM) volume in the DS population can provide insight into those associations in the more common sporadic AD. METHODS: Twenty-four adults (13 male, 11 female; 39±7 years) with DS underwent [11C]PiB, [18F]FDG, and volumetric MRI scans. Voxel-wise associations between PiB SUVR, FDG SUVR, and GM volume were investigated, with and without individual adjustments for variables of interest. RESULTS: Positive associations of PiB and age were widespread throughout the neocortex and striatum. Negative associations of FDG and age (frontal, parietal, and temporal cortex) and of GM volume and age (frontal and insular cortex) were observed. PiB and FDG were negatively associated in parietal cortex, after adjustment for GM volume. CONCLUSIONS: In adults with DS, early amyloid-ß accumulation in the striatum is divergent from sporadic AD; however, despite the early striatal amyloid-ß, glucose hypometabolism was confined to the typical AD-associated regions, which occurs similarly in autosomal dominant AD. Importantly, the glucose hypometabolism was not explained solely by increased partial volume effect due to GM volume reductions.

Parent Stress in a Randomized Clinical Trial of Atomoxetine and Parent Training for Children with Autism Spectrum Disorder.

We previously reported a 2 × 2 randomized clinical trial of atomoxetine (ATX) and parent training (PT) for attention deficit hyperactivity disorder (ADHD) symptoms and behavioral noncompliance in 128 children with autism spectrum disorder, ages 5-14 years. Children were randomized to one of four conditions: ATX alone, placebo alone, ATX + PT, or PT + placebo. Both ATX and PT improved some indices of ADHD and behavioral compliance. In this report, we describe parent stress over time and across conditions. All four treatments improved parent self-rated stress from baseline to week 10. However, there were no statistically significant differences between treatment groups. Significantly more improvement in parent stress scores was observed for clinical responders than non-responders.

A Randomized, Placebo-Controlled Trial of Metformin for the Treatment of Overweight Induced by Antipsychotic Medication in Young People With Autism Spectrum Disorder: Open-Label Extension.

OBJECTIVE: A previous study reported on a 16-week placebo-controlled, randomized clinical trial (RCT) of metformin for weight stabilization in 61 children and adolescents 6 to 17 years old with autism spectrum disorder who were prescribed atypical antipsychotics. The present study describes the results of a 16-week open-label extension. METHOD: Fifty-two participants from the acute trial (85%) entered the extension; 22 had been on metformin during the initial RCT and 30 had been on placebo. Participants were re-titrated to 500 mg twice a day (6- to 9-year-olds) or 850 mg twice a day (10- to 17-year-olds) during the open-label extension. Primary outcome measure was change in body mass index (BMI) z-score after 16 weeks; secondary outcomes were change in additional body composition and metabolic parameters. RESULTS: After 16 weeks of open-label treatment, participants initially taking placebo during the RCT had lower BMI z-scores (mean 16-week change -0.10, p = .004). Statistically significant improvements also were noted in secondary body composition measures (weight z-score and BMI and weight percentile) but not in metabolic variables. Participants who initially had been taking metformin during the 16-week RCT maintained prior decreases in BMI z-scores but did not have additional weight loss. Three participants discontinued treatment because of an adverse event. No significant changes were noted on metabolic measures, although the decrease in hemoglobin A1c was large (∼1 mmol) and consistent across the acute and open-label phases. CONCLUSION: Metformin can be effective for decreasing weight gain associated with atypical antipsychotic use and maintaining prior improvement in children and adolescents with autism spectrum disorder.

Longitudinal changes in amyloid positron emission tomography and volumetric magnetic resonance imaging in the nondemented Down syndrome population.

INTRODUCTION: Down syndrome (DS) arises from a triplication of chromosome 21, causing overproduction of the amyloid precursor protein and predisposes individuals to early Alzheimer's disease (AD). METHODS: Fifty-two nondemented adults with DS underwent two cycles of carbon 11-labeled Pittsburgh compound B ([11C]PiB) and T1 weighted magnetic resonance imaging (MRI) scans 3.0 ± 0.6 years apart. Standard uptake value ratio (SUVR) images (50-70 minutes; cerebellar gray matter [GM]) and GM volumes were analyzed in standardized space (Montreal Neurological Institute space). RESULTS: 85% of PiB(-) subjects remained PiB(-), whereas 15% converted to PiB(+), predominantly in the striatum. None reverted from PiB(+) to PiB(-). Increases in SUVR were distributed globally, but there were no decreases in GM volume. The PiB positivity groups differed in the percent rate of change in SUVR [PiB(-): 0.5%/year, PiB converters: 4.9%/year, and PiB(+): 3.7%/year], but not in GM volume. DISCUSSION: Despite the characteristic striatum-first pattern, the global rate of amyloid accumulation differs by pre-existing amyloid burden and precedes atrophy or dementia in the DS population, similar to general AD progression.

Adverse Events of Atomoxetine in a Double-Blind Placebo-Controlled Study in Children with Autism.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) symptoms, including inattention and over activity, occur in approximately one-third of children with autism spectrum disorder (ASD). We describe the rate and duration of adverse events in a randomized controlled trial of atomoxetine (ATX) and parent training (PT) for ADHD symptoms and noncompliance in children with ASD. METHODS: We conducted a 10-week, double-blind, 2 × 2 trial of ATX and PT with 128 children (ages 5-14) randomized to ATX alone, ATX+PT, placebo+PT, or placebo alone. For 6 weeks, ATX (or placebo) doses were clinically adjusted to a maximum of 1.8 mg/(kg·day) and maintained for an additional 4 weeks. An average of seven PT sessions were conducted in the two PT arms. Adverse events (AEs) were assessed through parent ratings of common symptoms on a seven-point Likert severity scale and through direct interviews with study medical staff. RESULTS: ATX was associated with decreased appetite and fatigue, but was otherwise well tolerated. Most reported AEs lasted 4 weeks or less. Unlike reports with typically developing (TD) children, there were no concerns with QTc changes or suicidal ideation. CONCLUSIONS: This study extends the findings of previous studies of ATX in ASD by documenting that the type of AEs was similar to that of TD children, with no significant safety concerns.

Leisure Activity and Caregiver Involvement in Middle-Aged and Older Adults With Down Syndrome.

The present study examined leisure activity and its association with caregiver involvement (i.e., residence and time spent with primary caregiver) in 62 middle-aged and older adults with Down syndrome (aged 30-53 years). Findings indicated that middle-aged and older adults with Down syndrome frequently participated in social and passive leisure activities, with low participation in physical and mentally stimulating leisure activities. Residence and time spent with primary caregiver were associated with participation in physical leisure activity. The findings suggest a need for support services aimed at increasing opportunities for participating in physical and mentally stimulating leisure activity by middle-aged and older adults with Down syndrome. These support services should partner with primary caregivers in order to best foster participation in physical leisure activity.

Atomoxetine and Parent Training for Children With Autism and Attention-Deficit/Hyperactivity Disorder: A 24-Week Extension Study.

OBJECTIVE: The authors previously reported on a 2-by-2 randomized clinical trial of individual and combined treatment with atomoxetine (ATX) and parent training (PT) for attention-deficit/hyperactivity disorder (ADHD) symptoms and behavioral noncompliance in 128 5- to 14-year-old children with autism spectrum disorder. In the present report, they describe a 24-week extension of treatment responders and nonresponders. METHOD: One-hundred seventeen participants from the acute trial (91%) entered the extension; 84 of these were in 2 subgroups: "treatment responders" (n = 43) from all 4 groups in the acute trial, seen monthly for 24 weeks, and "placebo nonresponders" (n = 41), treated with open-label ATX for 10 weeks. Participants originally assigned to PT continued PT during the extension; the remainder served as controls. Primary outcome measurements were the parent-rated Swanson, Nolan and Pelham ADHD scale and the Home Situations Questionnaire. RESULTS: Sixty percent (26 of 43) of treatment responders in the acute trial, including 68% of responders originally assigned to ATX, still met the response criteria at the end of the extension. The response rate of placebo nonresponders treated with 10-week open-label ATX was 37% (15 of 41), similar to the acute trial. Children receiving open-label ATX + PT were significantly more likely to be ADHD responders (53% versus 23%) and noncompliance responders (58% versus 14%) than those receiving open-label ATX alone. CONCLUSION: Most ATX responders maintained their responses during the extension. PT combined with ATX in the open-label trial appeared to improve ADHD and noncompliance outcomes more than ATX alone.

Metformin for Treatment of Overweight Induced by Atypical Antipsychotic Medication in Young People With Autism Spectrum Disorder: A Randomized Clinical Trial.

IMPORTANCE: Atypical antipsychotic medications are indicated for the treatment of irritability and agitation symptoms in children with autism spectrum disorder (ASD). Unfortunately, these medications are associated with weight gain and metabolic complications that are especially troubling in children and with long-term use. OBJECTIVE: To evaluate the efficacy of metformin for weight gain associated with atypical antipsychotic medications in children and adolescents with ASD (defined in the protocol as DSM-IV diagnosis of autistic disorder, Asperger disorder, or pervasive developmental disorder not otherwise specified), aged 6 to 17 years. DESIGN, SETTING, AND PARTICIPANTS: A 16-week, double-blind, placebo-controlled, randomized clinical trial was conducted at 4 centers in Toronto, Ontario, Canada; Columbus, Ohio; Pittsburgh, Pennsylvania; and Nashville, Tennessee. In all, 209 potential participants were screened by telephone, 69 individuals provided consent, and 61 participants were randomized to receive metformin or placebo between April 26, 2013, and June 24, 2015. INTERVENTIONS: Metformin or matching placebo titrated up to 500 mg twice daily for children aged 6 to 9 years and 850 mg twice daily for those 10 to 17 years. MAIN OUTCOMES AND MEASURES: The primary outcome measure was change in body mass index (BMI) z score during 16 weeks of treatment. Secondary outcomes included changes in additional body composition and metabolic variables. Safety, tolerability, and efficacy analyses all used a modified intent-to-treat sample comprising all participants who received at least 1 dose of medication. RESULTS: Of the 61 randomized participants, 60 participants initiated treatment (45 [75%] male; mean [SD] age, 12.8 [2.7] years). Metformin reduced BMI z scores from baseline to week 16 significantly more than placebo (difference in 16-week change scores vs placebo, -0.10 [95% CI, -0.16 to -0.04]; P = .003). Statistically significant improvements were also noted in secondary body composition measures (raw BMI, -0.95 [95% CI, -1.46 to -0.45] and raw weight, -2.73 [95% CI, -4.04 to -1.43]) but not in metabolic variables. Overall, metformin was well tolerated. Five participants in the metformin group discontinued treatment owing to adverse events (agitation, 4; sedation, 1). Participants receiving metformin vs placebo experienced gastrointestinal adverse events during a significantly higher percentage of treatment days (25.1% vs 6.8%; P = .005). CONCLUSIONS AND RELEVANCE: Metformin may be effective in decreasing weight gain associated with atypical antipsychotic use and is well tolerated by children and adolescents with ASD.

Caregiver Satisfaction with a Multisite Trial of Atomoxetine and Parent Training for Attention-Deficit/Hyperactivity Disorder and Behavioral Noncompliance in Children with Autism Spectrum Disorder.

OBJECTIVE: The purpose of this study was to examine caregiver satisfaction with the research experience in a randomized clinical trial of atomoxetine (ATX) and parent training (PT) for attention-deficit/hyperactivity disorder (ADHD) and behavioral noncompliance co-occurring with autism. METHODS: The Children with Hyperactivity and Autism Research Treatment Study (CHARTS) randomly assigned 128 children 5.00-14.11 years of age to four treatment groups (ATX + PT, ATX alone, PT + placebo[PBO], and PBO). Caregivers completed an 18 item questionnaire about their satisfaction with the research experience. We summarized caregiver responses with descriptive statistics and examined whether the responses were associated with demographic variables, treatment assignment, or the child's response to treatment (positive or negative). RESULTS: Ninety-three percent of caregivers (119) completed the questionnaire. When asked if they would join the study again if given the chance, 87% (103) responded "yes," 13% (15) responded "maybe," and 1% (1) responded "no." When asked if they would recommend the study to other caregivers of children with similar problems, 92% (109) responded "yes" and 8% responded (10) "maybe." Of the 59 Parent Satisfaction Questionnaire (PSQ) respondents who received PT, 75% (44) felt more confident in managing current child behaviors, 24% (14) felt that their level of confidence was unchanged, and 2% (1) felt less confident. Most caregivers expressed satisfaction with the study procedures, including the number of visits and the safety monitoring protocols. CONCLUSIONS: In general, caregivers were highly satisfied with their research experience. These findings may be useful for informing human subject committees and for designing study protocols that are appealing to families.

The effects of normal aging on amyloid-ß deposition in nondemented adults with Down syndrome as imaged by carbon 11-labeled Pittsburgh compound B.

INTRODUCTION: In Down syndrome (DS), the overproduction of amyloid precursor protein is hypothesized to predispose young adults to early expression of Alzheimer-like neuropathology. METHODS: PET imaging with carbon 11-labeled Pittsburgh compound B examined the pattern of amyloid-ß deposition in 68 nondemented adults with DS (30-53 years) to determine the relationship between deposition and normal aging. Standard uptake value ratio (SUVR) images were created with cerebellar gray matter as the reference region. RESULTS: Multiple linear regression revealed slight but highly significant (corrected P < .05) positive correlations between SUVR and age. The striatum showed the strongest correlation, followed by precuneus, parietal cortex, anterior cingulate, frontal cortex, and temporal cortex. CONCLUSION: There is an age-related amyloid-ß deposition in the DS population, but as a pattern of elevated cortical retention becomes apparent, the correlation of SUVR with age ceases to be significant. Factors unrelated to aging may drive an increase in deposition during early Alzheimer's disease pathogenesis.

Atomoxetine, Parent Training, and Their Combination in Children With Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: Impairments associated with attention-deficit/hyperactivity disorder (ADHD) and noncompliance are prevalent in children with autism spectrum disorder (ASD). However, ADHD response to stimulants is well below rates in typically developing children, with frequent side effects. Group studies of treatments for noncompliance are rare in ASD. We examined individual and combined-effectiveness of atomoxetine (ATX) and parent training (PT) for ADHD symptoms and noncompliance. METHOD: In a 3-site, 10-week, double-blind, 2 × 2 trial of ATX and PT, 128 children (ages 5-14 years) with ASD and ADHD symptoms were randomized to ATX, ATX+PT, placebo+PT, or placebo. ATX was adjusted to optimal dose (capped at 1.8 mg/kg/day) over 6 weeks and maintained for 4 additional weeks. Nine PT sessions were provided. Primary outcome measures were the parent-rated DSM ADHD symptoms on the Swanson, Nolan and Pelham (SNAP) scale and Home Situations Questionnaire (HSQ). RESULTS: On the SNAP, ATX, ATX+PT and placebo+PT were each superior to placebo (effect sizes 0.57-0.98; p values of .0005, .0004, and .025, respectively). For noncompliance, ATX and ATX+PT were superior to placebo (effect sizes 0.47-0.64; p values .03 and .0028, respectively). ATX was associated with decreased appetite but was otherwise well tolerated. CONCLUSION: Both ATX and PT resulted in significant improvement on ADHD symptoms, whereas ATX (both alone and combined with PT) was associated with significant decreases on measures of noncompliance. ATX appears to have a better side effects profile than psychostimulants in the population with ASD.

A review of atomoxetine effects in young people with developmental disabilities.

UNLABELLED: This review summarizes the pharmacokinetic characteristics, pharmacodynamic properties, common side effects, and clinical advantages and disadvantages associated with atomoxetine (ATX) treatment in typically developing children and adults with ADHD. Then the clinical research to date in developmental disabilities (DD), including autism spectrum disorders (ASD), is summarized and reviewed. Of the 11 relevant reports available, only two were placebo-controlled randomized clinical trials, and both focused on a single DD population (ASD). All trials but one indicated clinical improvement in ADHD symptoms with ATX, although it was difficult to judge the magnitude and validity of reported improvement in the absence of placebo controls. Effects of ATX on co-occurring behavioral and cognitive symptoms were much less consistent. Appetite decrease, nausea, and irritability were the most common adverse events reported among children with DD; clinicians should be aware that, as with stimulants, irritability appears to occur much more commonly in persons with DD than in typically developing individuals. Splitting the dose initially, starting below the recommended starting dose, and titrating slowly may prevent or ameliorate side effects. Patience is needed for the slow build-up of benefit. CONCLUSIONS: ATX holds promise for managing ADHD symptoms in DD, but properly controlled, randomized clinical trials of atomoxetine in intellectual disability and ASD are sorely needed. Clinicians and researchers should be vigilant for the emergence of irritability with ATX treatment. Effects of ATX on cognition in DD are virtually unstudied.

Psychopharmacological treatment of ADHD symptoms in children with autism spectrum disorder.

One of the most frequently reported behavioral concerns among children with autism spectrum disorder (ASD) is high rates of activity and inattention, symptoms that are often associated with attention deficit hyperactivity disorder (ADHD). Although there is a considerable body of research regarding the appropriate treatment of ADHD symptoms among typically developing children, the research among children with ASD is more limited. The evidence to date suggests that medication response rates among children with ASD are considerably lower than among typically developing children and that children with ASD tend to be at greater risk for experiencing side effects. The purpose of the present paper is to review the available research on the treatment of ADHD symptoms in children with ASD. This paper summarizes the data on a range of pharmacological options and provides specific recommendations for how best to clinically manage these symptoms.

Contextual emotion-regulation therapy for childhood depression: description and pilot testing of a new intervention.

OBJECTIVE: To pilot test the acceptability and efficacy of contextual emotion-regulation therapy (CERT), a new, developmentally appropriate intervention for childhood depression, which focuses on the self-regulation of dysphoria. METHOD: Two samples of convenience (n = 29, n = 2) served to verify some CERT constructs; it was then operationalized in a treatment manual. To pilot test CERT, 20 children (ages 7-12; 35% girls) with DSM dysthymic disorder (mean duration 24.4 months) entered an open, 30-session, 10-month, 4-phase trial, with 6- and 12-month follow-up. Assessments included independent clinical evaluations and self-rated questionnaires. RESULTS: Fifteen children completed theraphy, four were administratively terminated and one dropped out. Completers did not clinically differ from the rest, but they were more likely to have better educated and less depressed mothers and intact families. At the end of treatment, 53% of the completers had full and 13% partial remission of dysthymia (remission from superimposed major depression was 80%). By 6- and 12-month follow-up, 79% and 92% had full remission of dysthymia (p < 0.0001). Self-reported depressive and anxiety symptoms significantly declined by the end of treatment (p < .001) and remained so throughout follow-up. CONCLUSIONS: CERT enables clinicians to "match" the intervention to children's emotion regulatory needs and symptoms and was readily accepted by families. The promising results suggest the need for a randomized trial.

Mania in six preschool children.

At least nine cases of apparent preschool manic-depressive illness have been previously reported in the literature. In each of these children, a strong family history of affective illness was noted. In this report, the case histories of six preschool children ages 3 to 5 years with bipolar illness are summarized. These six were obtained from a sample of 36 consecutively hospitalized preschool children. Thus 17% of these hospitalized preschool children had bipolar illness. All had irritable mood, strong family history of affective illness, and previous presentation with symptoms of attention deficit hyperactivity disorder. They were diagnosed following a thorough clinical interview. Five children were treated with lithium; all five improved. Preschool mania exists as an identifiable entity and may respond to classic pharmacologic treatments.
