The Impact of Cognitive Behavioral Therapy on Sleep Problems in Autistic Children with Co-occurring Anxiety.

PURPOSE: This study seeks to examine the relationship between anxiety-symptom severity and sleep behaviors in autistic children receiving cognitive behavioral therapy (CBT). METHODS: We conducted a secondary-data analysis from a sample of 93 autistic youth, 4 to 14 years, participating in 24 weeks of CBT. Clinicians completed the Pediatric Anxiety Rating Scale (PARS) and parents completed the Children's Sleep Habits Questionnaire, Abbreviated/Short Form (CSHQ-SF) at baseline, mid-treatment, post-treatment and 3 months post-treatment. Mediation analysis evaluated the role of anxiety symptoms in mediating the effect of time in treatment on sleep. RESULTS: There was a negative association between time in treatment and scores on the CSHQ-SF (b = - 3.23, SE = 0.493, t = - 6.553, p < 0.001). Increased time in treatment was associated with decreased anxiety (b = - 4.66, SE = 0.405, t = - 11.507, p < 0.001), and anxiety symptoms decreased with CSHQ-SF scores (b = 0.322, SE = 0.112, t = 2.869, p = 0.005). The indirect effect of time in treatment on CSHQ-SF scores through PARS reduction was negative, but not statistically significant. CONCLUSION: Increased time in CBT was associated with decreased anxiety severity and improved sleep behaviors. Reductions in anxiety symptoms may mediate improvements in sleep problems, but larger sample sizes are necessary to explore this further.

Parent-Led Cognitive Behavioral Teletherapy for Anxiety in Autistic Youth: A Randomized Trial Comparing Two Levels of Therapist Support.

Parent-led cognitive behavioral therapy (CBT) is an efficient, promising form of therapy that may be well suited for autistic youth with anxiety disorders, though to date it has been minimally tested. In this study, 87 autistic youth (7 to 13 years old) with anxiety disorders and their parents were randomized to two forms of parent-led CBT in which parents led their child through a guided CBT workbook across 12 weeks: one with low therapist contact (four 30-minute telehealth calls), and one with standard therapist contact (ten 60-minute telehealth calls). Anxiety, functional impairment, and autism features significantly declined across therapy, without differences between groups. High satisfaction was reported in both groups, though significantly higher satisfaction ratings were reported in standard-contact CBT. Responder rates were 69% of completers at posttreatment (70% in standard contact, 68% in low contact) and 86% at 3-month follow-up (86% in standard contact, 87% in low contact). Low-contact CBT was estimated to incur an average cost of $755.70 per family compared with $1,978.34 in standard-contact CBT. Parent-led CBT with minimal or standard therapist contact both appear to be effective CBT delivery formats for autistic youth with anxiety disorders, with significant cost savings for low-contact CBT.

Family Accommodation in Children and Adolescents With Misophonia.

Family accommodation (e.g., reassurance, modifying routines, assisting avoidance) has not been explored among youth with misophonia but may have important clinical and intervention implications. We examined family accommodation in 102 children and adolescents with interview-confirmed misophonia and compared its frequency and content to family accommodation in 95 children and adolescents with anxiety disorders. Findings showed that family accommodation was ubiquitous in pediatric misophonia and may be even more frequent than in youth with anxiety disorders. Assisting the child, participating in misophonia-related behaviors, and modifying family routines were endorsed by more than 70% of parents of children with misophonia. Further, compared to parents of children with anxiety disorders, parents of children with misophonia more frequently reported child distress and anger when they did not accommodate. Family accommodation was moderately to strongly associated with misophonia severity even when accounting for co-occurring internalizing and externalizing symptoms and sociodemographic factors. This first study of family accommodation in pediatric misophonia suggests accommodation may be an important clinical feature. A notable study limitation is that the measure of misophonia did not delineate between adaptive versus maladaptive accommodations. Excessive and maladaptive accommodation may be one potential candidate to target in interventions when considered within a broader treatment plan. Importantly, adaptive accommodations should also be considered in day-to-day management if they improve functioning and quality of life.

Randomized trial comparing standard versus light intensity parent training for anxious youth.

OBJECTIVE: To examine the efficacy of the parent-led intervention Supportive Parenting for Anxious Childhood Emotions (SPACE) relative to a low-dose version of the protocol among children and adolescents with clinically significant anxiety and/or obsessive-compulsive disorder (OCD). METHOD: 68 youth (7-17) with anxiety/OCD and their parents were randomized to receive 12 weekly telehealth SPACE sessions (SPACE-Standard) or bibliotherapy plus 4 telehealth sessions over 12 weeks (SPACE-light). After screening, assessments were conducted via videoconferencing at baseline, post-treatment, and one-month follow-up. Independent evaluators were blind to treatment condition. RESULTS: Treatment condition did not predict whether a participant responded to the intervention (SPACE-Standard = 70%; SPACE-Light = 68%), nor was treatment condition a predictor of anxiety severity, parent-reported anxiety, or parent-/child-reported functional impairment at post-treatment or one-month follow-up. Youth in SPACE-Light self-reported higher post-treatment anxiety than youth in SPACE-standard, though this was no longer significant at one-month follow-up. Parent-reported family accommodation total change scores were associated with anxiety severity at post-treatment across both arms. CONCLUSION: This is the second randomized controlled trial (RCT) evaluating SPACE and provides further support for the efficacy of this intervention both in standard and low-dose formats. This study provides support for parent-led anxiety treatment targeting family accommodation as a primary mechanism of change and extends evidence of efficacy to a more clinically diverse sample.

Latin American Trans-ancestry INitiative for OCD genomics (LATINO): Study protocol.

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder. Worldwide, its prevalence is ~2% and its etiology is mostly unknown. Identifying biological factors contributing to OCD will elucidate underlying mechanisms and might contribute to improved treatment outcomes. Genomic studies of OCD are beginning to reveal long-sought risk loci, but >95% of the cases currently in analysis are of homogenous European ancestry. If not addressed, this Eurocentric bias will result in OCD genomic findings being more accurate for individuals of European ancestry than other ancestries, thereby contributing to health disparities in potential future applications of genomics. In this study protocol paper, we describe the Latin American Trans-ancestry INitiative for OCD genomics (LATINO, https://www.latinostudy.org). LATINO is a new network of investigators from across Latin America, the United States, and Canada who have begun to collect DNA and clinical data from 5000 richly phenotyped OCD cases of Latin American ancestry in a culturally sensitive and ethical manner. In this project, we will utilize trans-ancestry genomic analyses to accelerate the identification of OCD risk loci, fine-map putative causal variants, and improve the performance of polygenic risk scores in diverse populations. We will also capitalize on rich clinical data to examine the genetics of treatment response, biologically plausible OCD subtypes, and symptom dimensions. Additionally, LATINO will help elucidate the diversity of the clinical presentations of OCD across cultures through various trainings developed and offered in collaboration with Latin American investigators. We believe this study will advance the important goal of global mental health discovery and equity.

Depressive Symptoms in Autistic Youth with Anxiety Disorders.

OBJECTIVE: Anxiety and depression often coexist in youth and share overlapping symptomatology; however, little is known about the comorbidity of anxiety and depression in autistic youth. This study explores (1) the frequency of depressive symptoms among autistic children with clinically significant anxiety, (2) clinical variables that may be associated with elevated depressive symptoms, and (3) whether pretreatment depressive symptoms predict cognitive behavioral therapy (CBT) outcomes for anxiety. METHOD: Children aged 7 to 13 years (N = 87) and their parents participated in a randomized controlled trial comparing 2 versions of a parent-led, telehealth-delivered CBT program. Parents and children completed a variety of clinical assessments and self-report questionnaires before and after treatment. RESULTS: Fifty-seven percent of the child sample reported experiencing elevated depressive symptoms while roughly 20% of parents reported elevated depressive symptoms in their child. A strong association between anxiety and depression was found. Heightened feelings of loneliness, per child report, and functional impairment, per parent report, were found to be uniquely associated with elevated depressive symptoms. Finally, depressive symptoms were not a significant predictor of CBT outcomes for anxiety. CONCLUSION: Findings suggest high degrees of comorbidity between anxiety and depression among autistic children and that feelings of loneliness, anxiety, and functional impairment may be early indicators of mood-related concerns. Further research is needed to determine the full extent of the association between anxiety and depression and additional options for treating depression in autistic children.

Psychometric properties of the revised children's anxiety and depression scale (RCADS) for autistic youth without co-occurring intellectual disability.

Autistic youth often present with comorbid anxiety and depression yet there is a dearth of validated assessment tools. The Revised Children's Anxiety and Depression Scale (RCADS) assesses internalizing symptoms but there is little psychometric data in autistic youth. Treatment-seeking autistic youth with anxiety or obsessive-compulsive symptoms (N = 74; age 6-14 years), and caregivers, were administered the RCADS-Parent, RCADS-Child, and assessments of internalizing, externalizing symptoms and social impairment indicative of autism. RCADS-Parent and RCADS-Child total anxiety scores demonstrated excellent internal consistency, and the six subscales demonstrated acceptable-to-good internal consistency. The RCADS-Child and Parent total anxiety scores were weakly correlated, and neither child age nor gender altered the strength of this association. Convergent validity was supported by moderate-to-strong correlations with clinician and parent-reported anxiety symptoms. Support for divergent validity was mixed. Results provide support for the RCADS-Parent and RCADS-Child as reliable, valid measures of internalizing symptoms in autistic youth.

Promoting OCD WEllness and resilience (POWER) study: Rationale, design, and methods.

Obsessive-compulsive disorder (OCD) affects 1-2% of children and is associated with functional impairment and diminished quality of life. Several treatments are efficacious: cognitive behavioral therapy (CBT) with exposure and response prevention, serotonin reuptake inhibitor (SRI) monotherapy, and combined treatment (SRI + CBT). Expert clinician-informed practice parameters suggest that youth with mild to moderate OCD should be treated initially with CBT yet SRIs are frequently employed as the first-line intervention or in combination with psychotherapy in applied practice. Empirical data to guide SRI discontinuation in pediatric OCD are very limited. This study, Promoting OCD Wellness and Resiliency (POWER), aims to address this gap through a two phase, double-blinded, placebo-controlled, randomized controlled non-inferiority trial with the purpose of evaluating whether youth with OCD on an SRI can discontinue their medication after successful CBT augmentation and maintain wellness for a period of 24 weeks during which they receive maintenance CBT that models standard-of-care. In this paper we describe the rationale and methodological design of the POWER study.

Development and pilot testing of internet-delivered, family-based cognitive behavioral therapy for anxiety and obsessive-compulsive disorders in autistic youth.

Cognitive behavioral therapy adapted for autistic youth with anxiety and/or OCD has a strong evidence base, but few have access. A 12-week family-based, Internet-delivered cognitive behavioral therapy (iCBT) program for 7-15 year-old autistic youth with anxiety and/or OCD was developed as a potential method to address this problem. Quantitative and qualitative feedback from stakeholders (parents, youth, clinicians) was gathered on an initial draft of content before conducting a pilot trial. This feedback suggested high quality, engagement, usability, and informativeness of the material. Suggestions were incorporated into the treatment program that was tested in a pilot trial. Eight families were randomized to the iCBT program with either 1) weekly email support or 2) weekly email support plus biweekly telehealth check-ins, and seven of these families completed pre- and post-treatment assessments. An average reduction of 39% in anxiety severity was found, with six of the seven being classified as responders. Preliminary evidence suggests that family-based iCBT is an acceptable and promising treatment for autistic youth with anxiety and/or obsessive-compulsive disorders that should be further modified and tested in future work.

A Content Analysis of Self-report Child Anxiety Measures.

A clear understanding of the item content of psychological assessments is critical but often overlooked. This study describes the content overlap of seven commonly used and psychometrically validated measures of anxiety among children and adolescents. Symptom codes were created for all items across measures and items were sorted by these codes, which all fell into specific symptom categories. We conducted two analyses of all items: a "bottom-up" content categorization approach, which used symptom categories that were developed during this study, and a "top-down" DSM-5 categorization which mapped items onto symptoms of anxiety disorders in the DSM-5. Findings reveal a weak mean overlap across the included measures of youth anxiety. This suggests that the scope of anxiety measures should be carefully considered when designing studies, interpreting research, or assessing youth in clinical practice. Further research is needed to develop and establish a coding scheme for a more objective, comprehensive content analysis.

Obsessive-Compulsive Disorder Misdiagnosis among Mental Healthcare Providers in Latin America.

Mental healthcare professionals often have limited awareness of different obsessive-compulsive disorder (OCD) symptom presentations, which may contribute to years between OCD symptom onset and treatment initiation. While research has identified high rates of OCD misdiagnosis among clinicians from the United States and Canada, research on OCD symptom awareness among healthcare providers in Latin American (LATAM) regions is limited. In this study, LATAM mental healthcare providers (N = 83) provided diagnostic impressions based on five OCD vignettes: three with symptoms centered on taboo thoughts (sexual, harming others, and religion/scrupulosity) and two about contamination or symmetry obsessions. Rates of incorrect (non-OCD) diagnoses were significantly higher for the taboo thoughts vignettes (sexual, 52.7%; harm/aggression, 42.0%; and religious, 34.7%) vs. contamination obsessions (11.0%) and symmetry obsessions (6.9%). The OCD vignette depicting sexual obsessions was often attributed to a paraphilic disorder (36.5%). Bachelor's level clinicians had significantly lower odds of accurately identifying all three vignettes related to taboo thoughts compared to respondents with a graduate degree. Accurate identification of the three taboo vignettes was also associated with first-line psychological treatment recommendations (i.e., cognitive-behavioral therapy) even when controlling for respondents' theoretical orientation. Exposure was rarely mentioned when clinicians were prompted to provide treatment recommendations for each vignette (8-9% of the time for symmetry and contamination vignettes, 5-7% for taboo though vignettes). Like clinicians in the United States and Canada, mental health professionals in LATAM may misidentify OCD symptom presentations, particularly sexual obsessions, highlighting a need for education and training.

Meta-analysis: Pharmacologic Treatment of Restricted and Repetitive Behaviors in Autism Spectrum Disorders.

OBJECTIVE: To examine the efficacy of pharmacological treatments for restricted and repetitive behaviors (RRB) in autism spectrum disorders (ASD). METHOD: We searched PubMed, Embase, and CENTRAL to identify all double-blind, randomized, placebo-controlled trials that examined the efficacy of pharmacological agents in the treatment of ASD and measured RRB as an outcome. Our primary outcome was the standardized mean difference in rating scales of RRB. RESULTS: We identified 64 randomized, placebo-controlled trials involving 3,499 participants with ASD. Antipsychotics significantly improved RRB outcomes compared to placebo (standardized mean difference [SMD] = 0.28, 95% CIs = 0.08-0.49), z = 2.77, p = .01) demonstrating a small effect size. Larger significant positive effects on RRB in ASD were seen in individual studies with fluvoxamine, buspirone, bumetanide, divalproex, guanfacine, and folinic acid that have not been replicated. Other frequently studied pharmacological treatments in ASD including oxytocin, omega-3 fatty acids, selective serotonin reuptake inhibitors (SSRI), and methylphenidate did not demonstrate significant benefit in reducing RRB compared to placebo (oxytocin: SMD = 0.23, 95% CI = -0.01 to 0.47, z = 1.85, p = .06; omega-3 fatty acids: SMD = 0.19, 95% CI = -0.05 to 0.43, z = 1.54, p = .12; SSRI: SMD = 0.09, 95% CI = -0.21 to 0.39, z = 0.60, p = .56; methylphenidate: SMD = 0.18, 95% CI = -0.11 to 0.46, z = 1.23, p = .22). CONCLUSION: The results of the present meta-analysis suggest that currently available pharmacological agents have at best only a modest benefit for the treatment of RRB in ASD, with the most evidence supporting antipsychotic medications. Additional randomized controlled trials with standardized study designs and consistent and specific assessment tools for RRB are needed to further understand how we can best help ameliorate these behaviors in individuals with ASD.

Acute psychiatric care for pediatric patients.

Higher level or acute psychiatric care for youth is intended to be active but short-term treatment focussing on crisis stabilisation, assessment, safety monitoring, and longer-term treatment planning. The focus of this article is on describing common challenges and the effort to address these challenges through new approaches to acute psychiatric care for children and adolescents. The review finds that (1) inpatient paediatric psychiatry beds are in high demand and often difficult to access, (2) there are a number of common challenges these units face including managing length of stays, readmissions, and adverse events, and (3) there are encouraging therapeutic approaches adapted for this setting. There is still much work to be done to advance the evidence-base for acute psychiatric care for youth particularly in defining and assessing an effective admission. Paediatric psychiatry patients are a vulnerable population and call for our best tools to be put to use to improve the quality and safety of care.

Transneuronal Propagation of Pathologic α-Synuclein from the Gut to the Brain Models Parkinson's Disease.

Analysis of human pathology led Braak to postulate that α-synuclein (α-syn) pathology could spread from the gut to brain via the vagus nerve. Here, we test this postulate by assessing α-synucleinopathy in the brain in a novel gut-to-brain α-syn transmission mouse model, where pathological α-syn preformed fibrils were injected into the duodenal and pyloric muscularis layer. Spread of pathologic α-syn in brain, as assessed by phosphorylation of serine 129 of α-syn, was observed first in the dorsal motor nucleus, then in caudal portions of the hindbrain, including the locus coeruleus, and much later in basolateral amygdala, dorsal raphe nucleus, and the substantia nigra pars compacta. Moreover, loss of dopaminergic neurons and motor and non-motor symptoms were observed in a similar temporal manner. Truncal vagotomy and α-syn deficiency prevented the gut-to-brain spread of α-synucleinopathy and associated neurodegeneration and behavioral deficits. This study supports the Braak hypothesis in the etiology of idiopathic Parkinson's disease (PD).

Tauroursodeoxycholic Acid Protects against the Effects of P-Cresol-Induced Reactive Oxygen Species via the Expression of Cellular Prion Protein.

Mesenchymal stem cells (MSCs) could be a promising solution in the treatment of various diseases including chronic kidney disease (CKD). However, endoplasmic reticulum (ER) stress induced by ischemia in the area of application limits the integration and survival of MSCs in patients. In our study, we generated ER stress-induced conditions in MSCs using P-cresol. As P-cresol is a toxic compound accumulated in the body of CKD patients and induces apoptosis and inflammation through reactive oxygen species (ROS), we observed ER stress-induced MSC apoptosis activated by oxidative stress, which in turn resulted from ROS generation. To overcome stress-induced apoptosis, we investigated the protective effects of tauroursodeoxycholic acid (TUDCA), a bile acid, on ER stress in MSCs. In ER stress, TUDCA treatment of MSCs reduced ER stress-associated protein activation, including GRP78, PERK, eIF2α, ATF4, IRE1α, and CHOP. Next, to explore the protective mechanism adopted by TUDCA, TUDCA-mediated cellular prion protein (PrPC) activation was assessed. We confirmed that PrPC expression significantly increased ROS, which was eliminated by superoxide dismutase and catalase in MSCs. These findings suggest that TUDCA protects from inflammation and apoptosis in ER stress via PrPC expression. Our study demonstrates that TUDCA protects MSCs against inflammation and apoptosis in ER stress by PrPC expression in response to P-cresol exposure.
