Healthcare professionals and government officials have advised the use of personal protective equipment, such as face masks and face shields, to assist with limiting the spread of the SARS-CoV-2 (COVID-19). Due to the prevalence of challenging behavior associated with other medical routines, the present study evaluated a treatment package composed of graduated exposure, prompts, reinforcement, and escape extinction on tolerance of wearing a face covering for up to 5 min for 12 children with ASD in a systematic replication of Cox et al. (2017) and Sivaraman et al.

Attention deficit hyperactivity disorder (ADHD) is a common and highly heritable neurodevelopmental disorder with poorly understood pathophysiology and genetic mechanisms. A balanced chromosomal translocation interrupts in several members of a family with profound attentional deficit and myopia, and disruption of the gene was found in a separate unrelated individual with ADHD and myopia. encodes a brain-specific member of the adherens junction complex essential for postsynaptic and dendritic development, a site of potential pathophysiology in attentional disorders.

When a functional communication response (FCR) can be reliably occasioned, destructive behavior tends to be lower. However, the form of FCR may affect the durability of functional communication training, as missing FCR materials may promote resurgence. Experiment 1 demonstrated that resurgence of target responding was lower when a vocal FCR remained available but was placed on extinction compared to when a card-based FCR was unavailable.

Trisomy 13 is one of the three most common aneuploidy syndromes in live-born infants. It is associated with mortality rates as high as 90% within the first year of life, in large part, due to the high prevalence of severe congenital abnormalities that increase mortality and morbidity. However, life-saving and life-prolonging medical interventions are being performed at a higher rate for these infants, resulting in increased rates of survival.

Altered Cholesterol Biosynthesis Affects Drug Metabolism.

ACS Omega

March 2021

Munroe-Meyer Institute for Genetics and Rehabilitation, University of Nebraska Medical Center, Omaha, Nebraska 68105, United States.

The last step of cholesterol biosynthesis is the conversion of 7-dehydrocholesterol (7-DHC) into cholesterol, a reaction catalyzed by dehydrocholesterol reductase 7 (DHCR7). Investigation of the effect of 7 single-allele mutations on the metabolism of aripiprazole (ARI) and cariprazine (CAR) in maternally exposed transgenic pups revealed that ARI, CAR, and their active metabolites were decreased in the liver and brain of 7 . This difference in the drug and metabolite levels resulted in an increased turnover of ARI and CAR in tissues from 7 animals, indicating an enhanced metabolism, which was at least partially due to increased levels of Cyp2d6 in the liver of 7 mice.

Adolescence is a critical period for the development and refinement of several higher-level cognitive functions, including visual selective attention. Clinically, it has been noted that adolescents with cerebral palsy (CP) may have deficits in selectively attending to objects within their visual field. This study aimed to evaluate the neural oscillatory activity in the ventral attention network while adolescents with CP performed a visual selective attention task.

Dynamically allocating neural resources to salient features or objects within our visual space is fundamental to making rapid and accurate decisions. Impairments in such visuospatial abilities have been consistently documented in the clinical literature on individuals with cerebral palsy (CP), although the underlying neural mechanisms are poorly understood. In this study, we used magnetoencephalography (MEG) and oscillatory analysis methods to examine visuospatial processing in children with CP and demographically matched typically developing (TD) children.

Genes and environment interact during intrauterine life, and potentially alter the developmental trajectory of the brain. This can result in life-long consequences on brain function. We have previously developed two transgenic mouse lines that suppress Gad1 expression in parvalbumin (PVALB) and neuropeptide Y (NPY) expressing interneuron populations using a bacterial artificial chromosome (BAC)-driven miRNA-based silencing technology.

Renewal, the increase in behavior during extinction following context changes, may be particularly concerning during intervention for feeding disorders because context changes are often necessary for intervention generality and maintenance (Podlesnik et al., 2017). In the current study, we tested for renewal and evaluated a renewal-mitigation procedure when we transferred intervention from a therapist to a caregiver, from clinic to the home, and changed the foods the feeder presented.

Prescription Medications Alter Neuronal and Glial Cholesterol Synthesis.

ACS Chem Neurosci

February 2021

Department of Chemistry, Vanderbilt Institute of Chemical Biology and Vanderbilt Kennedy Center for Research on Human Development, Vanderbilt University, Nashville, Tennessee 37235, United States.

Article Synopsis
  • The study investigates how certain prescription medications affect cholesterol production in mouse brains, particularly in neurons and astrocytes, which are crucial for brain function.
  • Researchers exposed these cells to six different drugs that can cross the blood-brain barrier and analyzed the impact on cholesterol synthesis using advanced chemical techniques.
  • The findings revealed that several medications altered enzyme activity related to cholesterol biosynthesis, leading to increased levels of sterol intermediates and decreased cholesterol, which mimicked conditions similar to a specific genetic disorder affecting brain development.

Trazodone effects on developing brain.

Transl Psychiatry

February 2021

Department of Biochemistry and Molecular Biology, College of Medicine, University of Nebraska Medical Center, Omaha, 68198, NE, USA.

Trazodone (TRZ) is a commonly prescribed antidepressant with significant off-label use for insomnia. A recent drug screening revealed that TRZ interferes with sterol biosynthesis, causing elevated levels of sterol precursor 7-dehydrocholesterol (7-DHC). Recognizing the well-documented, disruptive effect of 7-DHC on brain development, we designed a study to analyze TRZ effects during pregnancy.

Child-Parent-Provider Interactions of a Child With Complex Communication Needs in an Inpatient Rehabilitation Facility: A Pilot Study.

Am J Speech Lang Pathol

January 2021

Department of Communication Sciences and Disorders, Pennsylvania State University, University Park.

Purpose Children with complex medical needs often require extensive hospitalizations in the first years of life. Many of these children also experience complex communication needs and use augmentative and alternative communication (AAC) strategies to interact with health care staff. Unfortunately, suboptimal communication experiences have been reported among these children, their families, and hospital staff; however, no studies have described the patterns of interactions beyond measures of self-report.

We replicated and extended Mitteer, Greer, Fisher, and Cohrs (2018) by examining the effects of a video model on inputting data into GraphPad Prism, which is a necessary skill for graph construction. We used a concurrent multiple-probe-across-behavior design with two behavior technicians to assess data-input and graphing skills separately prior to and during access to relevant video models. We evaluated the generality of the training procedures by assessing both skills during data-input-plus-graphing sessions without access to the video models.

The COVID-19 global health crisis compelled behavior analysts to consider alternatives to face-to-face services to treat children with feeding disorders. Research suggests telehealth is one method behavior analysts could use to initiate or continue assessment of and treatment for feeding disorders. In the current paper, we conducted pilot studies in which we analyzed chart records of patients with Avoidant/Restrictive Food Intake Disorder; who graduated from an intensive, day-treatment program; and transitioned to an outpatient follow-up program.
