Flow synthesis of Pt and Pt-Ag nanostructures towards hydrogen peroxide electroreduction.

Pt nanomaterials exhibit unique catalytic properties. However, the cost of Pt precursors and tedious conventional synthesis strategies limit their applications. In this study, a simple droplet-based synthesis of monometallic and bimetallic Pt nanostructures (NSs) of different morphologies using two different shape-directing agents [polyvinylpyrrolidone (PVP) and silver nitrate (AgNO)] by a 3D-printed reactor attached to a heater filament in continuous-flow is demonstrated.

A pilot, single-arm feasibility study of an integrated cognitive-behavioral treatment for anxiety in young autistic children.

Objective: Anxiety is prevalent in young autistic children under 7 years of age. Yet there is a paucity of empirically based interventions for this age group. DINO Strategies for Anxiety and Uncertainty Reduction (DINOSAUR) is an innovative cognitive behavioral intervention that seeks to optimize treatment response in young autistic children by targeting anxiety and the contributing mechanisms of intolerance of uncertainty and parental accommodation using a telehealth delivery model.

Anxiety in autistic preschool children: Phenomenology and a network analysis of correlates.

Anxiety disorders in autistic children are associated with significant functional impairment. Few studies have examined impairing anxiety presentations in autistic preschool children (i.e.

Psychometric Evaluation of the Autism Spectrum Rating Scales (6-18 Years Parent Report) in a Clinical Sample.

ASD is a neurodevelopmental disorder impacting 1 in 44 children and early identification of children with ASD is critical for the intervention. Several screening measures have been developed for early identification, including the Autism Spectrum Rating Scales, 6-18 years Parent Report (ASRS). The ASRS has been understudied, and the current study assessed the validity of the ASRS in a clinical sample of 490 children at a tertiary ASD-specialty clinic.

Exploring the Symptom Profiles of Intolerance of Uncertainty in Autistic Children.

Intolerance of uncertainty (IU) is a multidimensional construct involving maladaptive responses to uncertainty. IU is strongly associated with autism and anxiety, yet no studies have examined its symptom profile in autistic children. This study compares IU symptom profiles in autistic and NT children and in autistic children with and without anxiety using the Intolerance of Uncertainty Scale for Children.

Profiles and correlates of language and social communication differences among young autistic children.

Delays in early language development are characteristic of young autistic children, and one of the most recognizable first concerns that motivate parents to seek a diagnostic evaluation for their child. Although early language abilities are one of the strongest predictors of long-term outcomes, there is still much to be understood about the role of language impairment in the heterogeneous phenotypic presentation of autism. Using a person-centered, Latent Profile Analysis, we first aimed to identify distinct patterns of language and social communication ability in a clinic-based sample of 498 autistic children, ranging in age from 18 to 60 months ( = 33 mo, = 12 mo).

Replication study for ADOS-2 cut-offs to assist evaluation of autism spectrum disorder.

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) has been widely used for ASD assessment. While prior studies investigated sensitivity and specificity of ADOS-2 Modules 1-3, there has been limited research addressing algorithm cut-off scores to optimize ADOS-2 classification. The goal of this study was to assess algorithm cut-off scores for diagnosing ASD with Modules 1-3, and to evaluate alignment of the ADOS-2 classification with the best estimate clinical diagnosis.

Analysis of Race and Sex Bias in the Autism Diagnostic Observation Schedule (ADOS-2).

Importance: There are long-standing disparities in the prevalence of autism spectrum disorder (ASD) across race and sex. Surprisingly, few studies have examined whether these disparities arise partially out of systematic biases in the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), the reference standard measure of ASD.

Objective: To examine differential item functioning (DIF) of ADOS-2 items across sex and race.

Understanding educators' perspectives and experiences of COVID-19 in schools serving children with intellectual/developmental disabilities.

The COVID-19 pandemic has significantly impacted educators, both personally and professionally. However, very little is known about the extent of these impacts among educators' serving children with intellectual and developmental disabilities (IDD). The present study surveyed 230 educators (teachers, staff, and administrators) to assess their wellbeing, concerns during the pandemic, and perceived importance of various COVID-19 school mitigation strategies.

Psychiatric problems during the COVID-19 pandemic in children with autism spectrum disorder.

Children with autism spectrum disorder (ASD) are at elevated risk for psychiatric problems in response to the COVID-19 pandemic. This risk is due to their high rates of pre-pandemic psychiatric comorbidities and the pandemic's disruption to routines and access to necessary supports. Prior research has indicated that children with ASD may experience a worsening of specific psychiatric symptoms in response to COVID-19, though this body of work is limited in scope.

Dysregulation in Children and Adolescents Presenting to a Multidisciplinary Autism Clinic.

Research indicates that children with autism spectrum disorder (ASD) frequently exhibit dysregulation, which refers to poorly coordinated affective, behavioral, and cognitive responses to a given situation. We examined the characteristics of dysregulation in children presenting to a multidisciplinary ASD clinic for an ASD diagnostic evaluation. Sixty percent of children presenting for an ASD evaluation exhibited dysregulation.

Replication study of ADOS-2 Toddler Module cut-off scores for autism spectrum disorder classification.

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) has been regarded as the gold standard assessment of autism spectrum disorder (ASD). While clinical validity of ADOS-2 Modules 1-4 have been extensively studied, there has been very limited research examining the clinical validity of ADOS-2 Toddler Module. The goal of this study was to examine alignment of the ADOS-2 Toddler Module classification with clinicians' determination of ASD, with assessing cut-off scores for diagnosing ASD in toddlers.

Attention Deficit Hyperactivity Disorder Symptoms in Young Children with Autism Spectrum Disorder.

The purpose of the current study was to examine the prevalence of attention deficit hyperactivity disorder (ADHD) symptoms among young children with autism spectrum disorder (ASD), child and parent-related demographic and clinical correlates of ADHD symptoms, and the relationships between co-occurring mental health problems and ADHD symptoms. Data for this cross-sectional study came from 979 toddlers and preschoolers, ages 1.5-5 years, with ASD.

Ultrasensitive quantum dot-coupled-surface plasmon microfluidic aptasensor array for serum insulin detection.

Monitoring insulin levels in complex clinical matrices such as serum, holds immense importance in diagnosing type of diabetes. The present study reports the development of surface plasmon resonance aptamer based insulin sensor array in a four-channel microfluidic format which utilizes antibody attached to magnetic nanoparticles for capturing insulin from diabetic patient serum samples and surface immobilized plasmon enhancing quantum dots for signal amplification. The aptasensor gives minimal non-specific binding due to the immobilization of high molecular weight dendrimers on a cysteamine monolayer.

Investigating the factor structure of the child behavior checklist dysregulation profile in children and adolescents with autism spectrum disorder.

Dysregulation has been identified as an important risk factor for the development of psychiatric disorders in individuals with autism spectrum disorder (ASD). Therefore, it is necessary to empirically characterize dysregulation and identify psychometrically sound and readily available assessment methods in the ASD population. We sought to evaluate the factor structure of the Child Behavior Checklist-Dysregulation Profile (CBCL-DP), an established dysregulation measure in neurotypical children that is derived from the CBCL, in a large, clinically referred sample of children, ages 6-18 years, with ASD (n = 727).

Child and Family Characteristics that Predict Autism Spectrum Disorder Specialty Clinic Appointment Attendance and Alignment with Providers.

We examined factors contributing to initial appointment attendance, alignment between parents' pre-visit and clinicians' diagnostic impressions, and family commitment to follow-ups at an autism spectrum disorder (ASD) specialty clinic. Sample sizes were n = 6558 (initial), n = 1430 (alignment), and n = 1353 (follow-up). Parents completed surveys and clinicians provided their ASD diagnostic impressions.

Exploring Relationships Between Negative Cognitions and Anxiety Symptoms in Youth With Autism Spectrum Disorder.

Although cognitions are central to the conceptualization and treatment of anxiety in typically developing (TD) youth, there is scant research investigating automatic thoughts and their relationship with anxiety in youth with autism spectrum disorder (ASD). We sought to examine the types of automatic thoughts experienced by youth with ASD and co-occurring anxiety as well as the predictive relationship of anxiety to different types of automatic thoughts in 97 children, ages 8-14 years. We also explored the relationship of automatic thoughts and intolerance of uncertainty.

Electrochemical and surface plasmon insulin assays on clinical samples.

Diabetes is a complex immune disorder that requires extensive medical care beyond glycemic control. Recently, the prevalence of diabetes, particularly type 1 diabetes (T1D), has significantly increased from 5% to 10%, and this has affected the health-associated complication incidences in children and adults. The 2012 statistics by the American Diabetes Association reported that 29.

Relationships between autism spectrum disorder and intolerance of uncertainty.

Unlabelled: Intolerance of uncertainty (IU) is a dispositional risk factor involving maladaptive responding under conditions of uncertainty. Recent data indicate that IU is likely elevated in youth with autism spectrum disorder (ASD) and is positively correlated with anxiety. This study examined whether IU may be associated with ASD independent of anxiety.

Magnetite-Quantum Dot Immunoarray for Plasmon-Coupled-Fluorescence Imaging of Blood Insulin and Glycated Hemoglobin.

New microarray chip strategies that are sensitive and selective and that can measure low levels of important biomarkers directly in a blood sample are significant for improving human health by allowing timely diagnosis of an abnormal condition. Herein, we designed an antibody-aptamer immunoarray chip to demonstrate simultaneous measurement of blood insulin and glycated hemoglobin (HbA1c) levels relevant to diabetic and prediabetic disorders using a surface plasmon microarray with validation by fluorescence imaging. To accomplish both surface plasmon and fluorescence imaging on the same sample, we decorated magnetite nanoparticles with quantum dots for covalent immobilization of aptamers for subsequent capture and isolation of the aptamers specific for insulin and HbA1c markers from 20-times diluted whole blood samples.

Containing the Cost of Heart Failure Management: A Focus on Reducing Readmissions.

Heart failure (HF) consumes a large proportion of the total national health care budget. Incidence and prevalence of HF are increasing and may give rise to an unsustainable increase in health care spending. Hospitalizations account for the vast majority of HF-related expenses, and 20% to 25% of patients discharged with a diagnosis of HF are readmitted within 60 days.

Intolerance of Uncertainty Predicts Anxiety Outcomes Following CBT in Youth with ASD.

Modified cognitive-behavioral therapy (MCBT) has been demonstrated to reduce anxiety in youth with autism spectrum disorder (ASD). However, non-response rates are fairly high. Few studies have investigated factors associated with response.

Magnetic Optical Microarray Imager for Diagnosing Type of Diabetes in Clinical Blood Serum Samples.

Due to rapidly rising rates of diabetes and prediabetic conditions worldwide and the associated lethal complications, it is imperative to devise new diagnostic tools that reliably and directly measure insulin levels in clinical samples. Herein, we report a simple and sensitive direct imaging of insulin levels in diabetic patient samples using a surface plasmon resonance microarray imager (SPRi). To enhance sensitivity, we utilized magnetic nanoparticles (MNPs) to capture insulin from serum samples either directly or via a capture antibody immobilized on MNPs.

The Wearable Cardioverter Defibrillator in Nonischemic Cardiomyopathy: A US National Database Analysis.

Background: The wearable cardioverter defibrillator (WCD) is often used in patients at risk of sudden cardiac death (SCD) who are not yet candidates for an implantable cardioverter defibrillator (ICD). Newly diagnosed cardiomyopathy may be reversible, and a WCD may protect patients during the initial period of risk. We evaluate the benefit and compliance of the WCD in patients with nonischemic cardiomyopathy (NICM).
