Teaching clinicians and nurses to prepare for and present at interdisciplinary meetings through behavioral skills training.

Behavior analysts frequently collaborate with interdisciplinary colleagues to share information and make decisions about client services. This study evaluated the effects of behavioral skills training on preparation for and presentation during interdisciplinary review team meetings by clinicians (n = 4) and nurses (n = 4) at a residential school for students with intellectual and neurodevelopmental disabilities. The primary dependent measure was the percentage of preparation and presentation steps from task-analyzed behavior checklists that the participants implemented correctly.

Impact of a Training Package to Improve the Effectiveness of Descriptive Assessment Data.

Identifying the maintaining contingencies of problem behavior can lead to effective treatment that reduces the occurrence of problem behavior and increases the potential for the occurrence of alternative behaviors. Many studies use descriptive assessments, but results vary in effectiveness and validity. Comparative research further supports the superior utility of analog functional analyses over descriptive assessments, but clinicians continue to report the consistent use of descriptive assessments in practice.

Psychotropic Medication Monitoring in a Human Services Organization for Children with Autism Spectrum Disorder: Description and Evaluation of Interdisciplinary Team Review.

Children with autism spectrum disorder (ASD) are often prescribed psychotropic medications but pharmacotherapy is typically conducted and evaluated based on clinical judgement without reference to objective measurement of treatment effectiveness and combined efficacy of pharmacological-behavioral interventions. We describe an interdisciplinary review team (IRT) model at a human services organization for children with ASD that was designed to standardize a process of psychotropic medication monitoring through (1) coordinated involvement of medical, nursing, behavior analyst, and special education professionals, (2) parent-guardian participation, (3) data-driven decision making, and (4) high-level administrative support. Our description includes case illustrations of medication reduction-elimination trials with five students and social validity assessment of IRT clinicians, nurses, and parent-guardians.

Behavioral Training and Performance Management of Human Services Organization Care Providers During the COVID-19 Pandemic.

Objectives: This report describes a model of training and performance management that was designed for and implemented with care providers at a residential school for children with neurodevelopmental and intellectual disabilities in response to the COVID-19 pandemic. The model focused on health and safety concerns, risk mitigation, and intervention integrity.

Methods: Procedures followed an applied behavior analysis (ABA) and organizational behavior management (OBM) framework.

Interdisciplinary Collaboration Training: An Example of a Preservice Training Series.

In recent years, there has been discussion of the need for training behavior analysts in collaboration skills. There is some consensus that these skills are needed to improve outcomes with clients and with colleagues. Specifically, students of behavior analysis and behavior-analytic practitioners need to learn the skills associated with functioning effectively in interdisciplinary teams.

Behavioral assessment and faded bedtime intervention for delayed sleep-onset in an adult with autism spectrum disorder.

Faded bedtime has been evaluated as a behavioral intervention for delayed sleep-onset principally with children and youth who have intellectual and developmental disabilities in hospital and home settings. The present case report describes behavioral assessment and faded bedtime intervention in a 21-year old adult man with autism spectrum disorder at a community-based group home. The study also documented the effects of family home visits on the man's sleep when he returned to the group home.

Considerations in developing medical countermeasures against chemical ocular toxicity.

The Chemical Countermeasures Research Program (CCRP) was established in 2006 by the National Institute of Allergy and Infectious Diseases (NIAID/NIH) on behalf of the National Institutes of Health Office of the Director (NIH OD). It is a trans-NIH initiative to expedite the discovery and early development of medical countermeasures (MCMs) that can reduce mortality and serious morbidity during and after large consequence public health emergency involving the deliberate or accidental large-scale release of highly toxic chemicals (HTCs).

The National Institutes of Health Chemical Countermeasures Research Program (NIH CCRP): A collaborative opportunity to develop effective and accessible chemical medical countermeasures for the American people.

The United States Department of Health and Human Services (HHS) leads the nation in preventing, preparing for, and responding to the adverse health effects of public health emergencies and disasters. In addition to biological, radiological and nuclear agents, the risk of a high consequence public health emergency due to the intentional and/or accidental release of chemical agents is a major growing concern of the US government. As such, the federal government is fully committed to address public health security threats posed by chemicals.

Teaching students with autism spectrum disorder to tolerate haircutting.

We describe intervention with 2 adolescent male students who had autism spectrum disorder (ASD) and resisted haircutting performed by care providers at a residential school. The students were exposed to a graduated hierarchy of steps including the presence of hair clippers, and increased duration of hair clippers against their scalp and hair. Edible reinforcement was presented contingent on completion of a step without interfering behavior.

Supporting Fundamental Chemical Toxicology Research To Inform Medical Countermeasure Developments: The National Institutes of Health Chemical Countermeasures Research Program.

A high-consequence chemical emergency is a major public health concern. In the United States, the National Institute of Allergy and Infectious Diseases within the National Institutes of Health pioneers discovery and early development of critical medical countermeasures against chemical threats.

National Institutes of Health (NIH) Executive Meeting Summary: Developing Medical Countermeasures to Rescue Opioid-Induced Respiratory Depression (a Trans-Agency Scientific Meeting)-August 6/7, 2019.

On August 6th, 2019, a two-day trans-agency scientific meeting was convened by the United States (U.S.) National Institute of Allergy and Infectious Diseases (NIAID/NIH) on the research and development of medical countermeasures (MCMs) and treatment strategies to mitigate synthetic opioid-induced toxicities.

Improving Classroom Appearance and Organization Through a Supervisory Performance Improvement Intervention.

This study evaluated the effects of a supervisory intervention on maintenance of appearance and organization in classrooms at a human services program for children and youths. The intervention combined performance feedback to classroom staff, public posting of performance outcomes, and eligibility for a performance-based incentive. Conducted in a multiple-baseline design, intervention was immediately and consistently effective in all classrooms.

The synthesis of OspD3 (ShET2) in Shigella flexneri is independent of OspC1.

Shigella flexneri is a Gram-negative pathogen that invades the colonic epithelium and causes millions of cases of watery diarrhea or bacillary dysentery predominately in children under the age of 5 years in developing countries. The effector Shigella enterotoxin 2 (ShET2), or OspD3, is encoded by the sen or ospD3 gene on the virulence plasmid. Previous literature has suggested that ospD3 is in an operon downstream of the ospC1 gene, and expression of both genes is controlled by a promoter upstream of ospC1.

Effects of alternative responses on behavior exposed to noncontingent reinforcement.

Noncontingent reinforcement (NCR) may decrease the frequency of behavior by either inducing satiation or terminating the response-reinforcer contingency (extinction). Another possibility is that the target behavior is replaced by other behaviors maintained by preexisting contingencies. We conducted 2 experiments in which we allowed access to a target response and several alternatives.

Assessment and treatment of social avoidance.

Problem behavior maintained by social-negative reinforcement often is evoked by a specific type of social interaction--the presentation of task demands. This study involved assessment and treatment of a more general form of social avoidance in which the establishing operation (EO) for problem behavior consisted of social interaction per se. Four subjects exhibited high rates of problem behavior during the play or demand conditions of a functional analysis (FA).

Evaluation of the divided attention condition during functional analyses.

A common condition included in most functional analyses (FAs) is the attention condition, in which the therapist ignores the client by engaging in a solitary activity (antecedent event) but delivers attention to the client contingent on problem behavior (consequent event). The divided attention condition is similar, except that the antecedent event consists of the therapist conversing with an adult confederate. We compared the typical and divided attention conditions to determine whether behavior in general (Study 1) and problem behavior in particular (Study 2) were more sensitive to one of the test conditions.

Test-specific control conditions for functional analyses.

Most functional analyses of problem behavior include a common condition (play or noncontingent reinforcement) as a control for both positive and negative reinforcement. However, test-specific conditions that control for each potential source of reinforcement may be beneficial occasionally. We compared responding during alone, ignore, play, and differential reinforcement of other behavior (DRO) control conditions for individuals whose problem behavior was maintained by positive or negative reinforcement.

Chromosomal and plasmid-encoded factors of Shigella flexneri induce secretogenic activity ex vivo.

Shigella flexneri is a Gram-negative, facultative intracellular pathogen that causes millions of cases of watery or bloody diarrhea annually, resulting in significant global mortality. Watery diarrhea is thought to arise in the jejunum, and subsequent bloody diarrhea occurs as a result of invasion of the colonic epithelium. Previous literature has demonstrated that Shigella encodes enterotoxins, both chromosomally and on the 220 kilobase virulence plasmid.

Elimination of position-biased responding in individuals with autism and intellectual disabilities.

Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training trials were conducted in which a stimulus of known lesser quality was presented as one of the choices.

False-positive tangible outcomes of functional analyses.

Functional analysis (FA) methodology is the most precise method for identifying variables that maintain problem behavior. Occasionally, however, results of an FA may be influenced by idiosyncratic sensitivity to aspects of the assessment conditions. For example, data from several studies suggest that inclusion of a tangible condition during an FA may be prone to a false-positive outcome, although the extent to which tangible reinforcement routinely produces such outcomes is unknown.

Induction of increased permeability of polarized enterocyte monolayers by enterotoxigenic Escherichia coli heat-labile enterotoxin.

Enterotoxigenic Escherichia coli (ETEC) is a common cause of acute diarrhea in resource-poor settings. We report that some ETEC strains elicit a reduction in trans-epithelial electrical resistance (TER) in polarized T84 epithelial cell monolayers. The effect was irreversible up to 48 hours after a three-hour infection and was observed with heat-labile enterotoxin (LT)-producing strains, but not with heat-stable enterotoxin (ST)-producing strains.

Enteroaggregative Escherichia coli disrupts epithelial cell tight junctions.

Enteroaggregative Escherichia coli (EAEC) is responsible for inflammatory diarrhea in diverse populations, but its mechanisms of pathogenesis have not been fully elucidated. We have used a previously characterized polarized intestinal T84 cell model to investigate the effects of infection with EAEC strain 042 on tight junction integrity. We find that infection with strain 042 induces a decrease in transepithelial electrical resistance (TER) compared to uninfected controls and to cells infected with commensal E.

An in vitro system to model the establishment and reactivation of HIV-1 latency.

HIV-1 establishes latency primarily by infecting activated CD4(+) T cells that later return to quiescence as memory cells. Latency allows HIV-1 to evade immune responses and to persist during antiretroviral therapy, which represents an important problem in clinical practice. The lack of a valid cellular model to study HIV-1 latency has hindered advances in the understanding of its biology.

Increased interferon alpha expression in circulating plasmacytoid dendritic cells of HIV-1-infected patients.

Background: The role of plasmacytoid dendritic cells (pDC) and interferon alpha (IFN alpha) in HIV-1 infection is still unclear. On one hand, HIV-1 disease is associated with a progressive decline of pDC, which displays reduced ability to produce IFN alpha after in vitro challenge. On the other hand, high IFN alpha serum levels in HIV-1-infected individuals have been proposed to promote immune hyper-activation and disease progression.
