Comparing Agency Leader and Therapist Perspectives on Evidence-Based Practices: Associations with Individual and Organizational Factors in a Mental Health System-Driven Implementation Effort

Agency leaders and therapists are essential stakeholders in implementation of evidence-based practices (EBPs) within publicly-funded mental health services. Little is known about how these stakeholders differ in their perceptions of specific EBPs and which individual and organizational factors differentially influence these perceptions. Within the context of a system-driven implementation of multiple EBPs, survey data from 160 leaders and 720 therapists were examined to assess differences in perceptions of six EBPs. Findings indicated that leaders and therapists have unique perspectives and preferences regarding EBPs that are shaped by distinct sociodemographic and professional characteristics and aspects of organizational functioning.     

Biomarker discovery in cardiac allograft vasculopathy using targeted aptamer proteomics

Cardiac allograft vasculopathy (CAV) limits long-term survival after heart transplantation. Non-invasive evaluation is challenging, and currently, there is no validated biomarker for CAV diagnosis or prognostication. To identify potential candidate CAV biomarkers, we utilized the Slow Off-rate Modified Aptamer (SOMAscan) assay, which evaluates over 1000 serum proteins, including many relevant to biological pathways in CAV. We evaluated three heart transplant patient groups according to angiographic ISHLT CAV grade: CAV_1-2 (mild-moderate CAV), CAV₃ (severe CAV), and CAV₀ (normal control). SOMAscan assays were performed and proteins quantitated. Comparisons of proteins between study groups were performed using one-way ANOVA (false discovery rate q-value < 0.10). Thirty-one patients (12 mild-moderate CAV, 9 severe CAV, 10 controls) were included: 81% male, median age 57 years and median 1.1 years post-transplant. Compared to controls, patients with mild-moderate CAV had similar characteristics, while patients with severe CAV had longer time from transplant and increased allosensitization. Statistical/bioinformatics analysis identified 14 novel biomarkers for CAV, including 4 specific for mild-moderate CAV. These proteins demonstrated important actions including apoptosis, inflammation, and platelet/coagulation activation. Upon preliminary receiver operating characteristics curve analysis, our protein biomarkers showed moderate-to-high discriminative ability for CAV (area under curve: 0.72 to 0.94). These candidate biomarkers are being validated in prospective studies.     

Training Community Mental Health Therapists to Deliver a Package of Evidence-Based Practice Strategies for School-Age Children with Autism Spectrum Disorders: A Pilot Study

Research on moving evidence-based practice (EBP) intervention strategies to community service settings for children with autism spectrum disorders (ASD) is urgently needed. The current pilot study addresses this need by examining the feasibility, acceptability and preliminary outcomes of training therapists practicing in community mental health (CMH) clinics to deliver a package of EBP strategies aimed to reduce challenging behaviors in school-age children with ASD. Results indicate that CMH therapists participated in both initial and ongoing training, were able to deliver the intervention with fidelity, and perceived the intervention strategies as useful. Parents participated in almost all sessions with their children and remained in therapy when therapists delivered the intervention. Meaningful reductions in child problem behaviors occurred over 5 months providing promising support for the intervention.     

Discovery of a fluoroindolo[2,3-a]carbazole clinical candidate with broad spectrum antitumor activity in preclinical tumor models superior to the marketed oncology drug, CPT-11

A series of fluoroglycosylated fluoroindolocarbazoles was examined with respect to their topoisomerase I activity, cytotoxicity, and selectivity. The lead clinical candidate from this series, BMS-250749, displays broad spectrum antitumor activity superior to CPT-11 against some preclinical xenograft models, including curative antitumor activity against Lewis lung carcinoma.     

Therapist Perspectives on Community Mental Health Services for Children with Autism Spectrum Disorders

This mixed methods study examined therapist perspectives on serving children with autism spectrum disorders (ASD) in community mental health (CMH) clinics. One hundred therapists completed a survey about their experiences with this population and 17 participated in subsequent focus groups to clarify and expand survey results. Results indicate that CMH therapists serve many children with ASD for behavior or other psychiatric problems and perceive serving this population as challenging and frustrating due to their limited training. Therapists are highly motivated for comprehensive ASD training on ASD characteristics and intervention strategies. These data were used to tailor and package evidence-based intervention strategies for delivery in CMH services.     

Pigmented villonodular synovitis of the elbow: a case report and literature review

Pigmented villonodular synovitis is a well-described, benign proliferative disorder of the synovium that rarely affects the elbow joint. Only 12 cases have been reported in this site. A case is presented of elbow involvement by pigmented villonodular synovitis that was documented by magnetic resonance imaging before surgery and monitored until recurrence.     

Absence of effect of chronic nicotine administration on amyloid beta peptide levels in transgenic mice overexpressing mutated human APP (Sw, Ind)

Studies have indicated that nicotine has disease-modifying and cognitive-enhancing properties in Alzheimer's disease (AD). Nicotine has been proposed to be neuroprotective through anti-amyloid beta (Abeta) effects, anti-excitotoxic effects, and anti-free radical effects. Previously, conflicting data from Abeta plaque developing transgenic mice have shown significant Abeta-lowering effects, or alternatively no effects, of nicotine administration. In this study, dosing of transgenic mice (J20 strain) with mutated human APP (Swedish mutations: K670N and M671L and Indiana mutation: V717F) transgene, with nicotine in drinking water for 20 weeks did not have a significant effect on total levels of Abeta 40 or 42 in hippocampus or cortex. This treatment strategy resulted in increased levels of nicotinic acetylcholine receptor activity, and reduced levels of cortical glial fibrillary acidic protein, but had no effect on cortical synaptophysin protein levels. The J20 mouse strain produces higher levels of Abeta 42, the more pathogenic form of Abeta, than Abeta 40 compared to other Abeta plaque developing mouse strains; this could account for differences in effectiveness of nicotine in transgenic mice models of AD.
