Program evaluation of service delivery trends in early intervention

This study was conducted to evaluate utilization of seventeen services, including occupational and physical therapy, provided through Nevada Early Intervention Services (NEIS)-South between July 2003 and June 2005. Eligibility for services was determined by the child\u27s qualifying diagnosis according to the Individuals with Disabilities Act (1997) and was based on either (1) Diagnostic and Statistical Manual of Mental Disorders-4th Edition Text Revision (DSM-IV-TR) or medical diagnosis or (2) developmental delay as defined by the Nevada Administrative Code for children ages birth through three years. Analyses of the services provided based on the eligibility criteria was undertaken to determine service referral trends and provide suggestions to NEIS-South based on compiled program data; All children who received an initial Individualized Family Service Plan through NEIS-South during the two year period were included in this study with a resultant 1516 files analyzed. The premise of the study was that all children referred to NEIS-South received necessary services. Two specific research questions were addressed in this study. First, did children who possessed a DSM-IV-TR or medical diagnosis as the qualifier for Part C services receive more early intervention services than children diagnosed with developmental delay based on the types of services per month and interventions received? Second, did children with a DSM-IV-TR or medical diagnosis receive occupational and/or physical therapy more frequently than children with a diagnosis of developmental delay?;Data analysis indicated that 486 (32.1%) of children qualified for services through NEIS-South based on a DSM-IV-TR or medical diagnosis. There were 1030 (67.9%) children who qualified based on a diagnosis of developmental delay. Three of the seventeen identified services received the largest number of referrals and were determined to be statistically significant through Chi square analyses. These services were speech language pathology (n = 642, 14.74%), specialized instruction (n = 1231, 28.27%), and parent/family training (n = 1450, 33.3%); Recommendations for evaluation of service categories and training programs were provided for NEIS-South as well as agencies bidding to provide subcontracting services through NEIS-South

Decision-making in communication aid recommendations in the UK : cultural and contextual influencers

High-tech communication aids are one form of augmentative and alternative communication (AAC) intervention offered to children following an assessment process to identify the most appropriate system based on their needs. Professional recommendations are likely to include consideration of child characteristics and communication aid attributes. Recommendations may be influenced by contextual factors related to the cultural work practices and service context of professionals involved, as well as by contextual factors from the child’s life including their family environment and wider settings. The aim of this study was to explore the influence of cultural and contextual factors on the real-time decision-making processes of specialized AAC professionals in the UK. A total of six teams were recruited to the study. Each team carried out an assessment appointment related to a communication aid recommendation for a child and family. Following the appointment, each team participated in a focus group examining their decision-making processes during the preceding assessment. Inductive coding was used to analyse the transcribed data, and three organizing themes emerged relating to the global theme of Cultural and Contextual Influencers on communication aid decision-making. An explanatory model was developed to illustrate the funnelling effect that contextual factors may have on decision-making, which can substantially alter the nature and timing of a communication aid recommendation. Implications for clinical practice and future research are discussed

Professionals’ decision-making in recommending communication aids in the UK : competing considerations

Existing research suggests the provision of communication aids for children with complex communication needs can have significant positive impacts on health and quality-of-life. The process of clinical decision-making related to the recommendation of high-tech communication aids is not well documented or evaluated, and research evidence related to the provision of these aids remains limited. This study aimed to understand the factors that specialized AAC professionals in the UK consider when recommending high-tech communication aids. Purposive sampling was used to recruit teams to six focus groups, each of which centred on a team’s recent recommendation process (i.e. a discussion following a real-time assessment session, where the team attempted to arrive at an agreed recommendation for a specific child). Thematic network analysis was used to interpret data from the focus group discussions. Participants identified a wide range of child characteristics, access features, and communication aid attributes in weighing up decisions for individual children. Findings suggest that specialized AAC professionals in the UK prioritize access features over language considerations in their communication aid recommendations. An explanatory model was developed to illustrate the interaction effect that several competing considerations may have on decision-making. Implications for clinical practice and future research are discussed

Nanomedicines for the delivery of biologics

A special symposium of the Academy of Pharmaceutical Sciences Nanomedicines Focus Group reviewed the current status of the use of nanomedicines for the delivery of biologics drugs. This meeting was particularly timely with the recent approval of the first siRNA-containing product Onpattro™ (patisiran), which is formulated as a lipid nanoparticle for intravenous infusion, and the increasing interest in the use of nanomedicines for the oral delivery of biologics. The challenges in delivering such molecules were discussed with specific emphasis on the delivery both across and into cells. The latest developments in Molecular Envelope Technology® (Nanomerics Ltd, London, UK), liposomal drug delivery (both from an academic and industrial perspective), opportunities offered by the endocytic pathway, delivery using genetically engineered viral vectors (PsiOxus Technologies Ltd, Abingdon, UK), Transint™ technology (Applied Molecular Transport Inc., South San Francisco, CA, USA), which has the potential to deliver a wide range of macromolecules, and AstraZeneca’s initiatives in mRNA delivery were covered with a focus on their uses in difficult to treat diseases, including cancers. Preclinical data were presented for each of the technologies and where sufficiently advanced, plans for clinical studies as well as early clinical data. The meeting covered the work in progress in this exciting area and highlighted some key technologies to look out for in the future

Unsaturated glycoceramides as molecular carriers for mucosal drug delivery of GLP-1

The incretin hormone Glucagon-like peptide 1 (GLP-1) requires delivery by injection for the treatment of Type 2 diabetes mellitus. Here, we test if the properties of glycosphingolipid trafficking in epithelial cells can be applied to convert GLP-1 into a molecule suitable for mucosal absorption. GLP-1 was coupled to the extracellular oligosaccharide domain of GM1 species containing ceramides with different fatty acids and with minimal loss of incretin bioactivity. When applied to apical surfaces of polarized epithelial cells in monolayer culture, only GLP-1 coupled to GM1-ceramides with short-or cis-unsaturated fatty acids trafficked efficiently across the cell to the basolateral membrane by transcytosis. In vivo studies showed mucosal absorption after nasal administration. The results substantiate our recently reported dependence on ceramide structure for trafficking the GM1 across polarized epithelial cells and support the idea that specific glycosphingolipids can be harnessed as molecular vehicles for mucosal delivery of therapeutic peptides

Attributes of communication aids as described by those supporting children and young people with AAC

Background Those supporting children and young people who use augmentative and alternative communication (AAC) contribute to ongoing complex decision-making about communication aid selection and support. Little is known about how these decisions are made in practice and how attributes of the communication aid are described or considered. Aims To understand how communication aid attributes were described by those involved in AAC recommendations and support for children and young people, and how these attributes were described as impacting on AAC use. Methods & Procedures A secondary qualitative analysis was completed of interview and focus group data from 91 participants involved in the support of 22 children and young people. Attributes of communication aids described by participants were extracted as themes and this paper reports a descriptive summary of the identified software (non-hardware) attributes. Main Contribution Decisions were described in terms of comparisons between commercially available pre-existing vocabulary packages. Attributes related to vocabulary, graphic representation, consistency and intuitiveness of design, and ease of editing were identified. Developmental staging of vocabularies, core and fringe vocabulary, and vocabulary personalization were attributes that were described as being explicitly considered in decisions. The potential impact of graphic symbol choice did not seem to be considered strongly. The physical and social environment was described as the predominant factor driving the choice of a number of attributes. Conclusions & Implications Specific attributes that appear to be established in decision-making in these data have limited empirical research literature. Terms used in the literature to describe communication aid attributes were not observed in these data. Practice-based evidence does not appear to be supported by the available research literature and these findings highlight several areas where empirical research is needed in order to provide a robust basis for practice. What This Paper Adds What is already known on the subject Communication aid attributes are viewed as a key consideration by practitioners and family members in AAC decision-making; however, there are few empirical studies investigating language and communication attributes of communication aids. It is important to understand how those involved in AAC recommendations and support view communication aid attributes and the impact different attributes have. What this paper adds to existing knowledge This study provides a picture of how communication aids are described by practitioners and family members involved in AAC support of children and young people. A range of attributes is identified from the analysis of these qualitative data as well as information about how participants perceive these attributes as informing decisions. What are the potential or actual clinical implications of this work? This study provides a basis on which practitioners and others involved in AAC support for children and young people can review and reflect on their own practice and so improve the outcomes of AAC decisions. The study provides a list of attributes that appear to be considered in practice and so also provides a resource for researchers looking to ensure there is a strong empirical basis for AAC decisions

CRISPR-delivery particles targeting nuclear receptor-interacting protein 1 (Nrip1) in adipose cells to enhance energy expenditure

RNA-guided, engineered nucleases derived from the prokaryotic adaptive immune system CRISPR-Cas represent a powerful platform for gene deletion and editing. When used as a therapeutic approach, direct delivery of Cas9 protein and single-guide RNA (sgRNA) could circumvent the safety issues associated with plasmid delivery and therefore represents an attractive tool for precision genome engineering. Gene deletion or editing in adipose tissue to enhance its energy expenditure, fatty acid oxidation, and secretion of bioactive factors through a browning process presents a potential therapeutic strategy to alleviate metabolic disease. Here, we developed CRISPR-delivery particles, denoted CriPs, composed of nano-size complexes of Cas9 protein and sgRNA that are coated with an amphipathic peptide called Endo-Porter that mediates entry into cells. Efficient CRISPR-Cas9-mediated gene deletion of ectopically expressed GFP by CriPs was achieved in multiple cell types, including a macrophage cell line, primary macrophages, and primary pre-adipocytes. Significant GFP loss was also observed in peritoneal exudate cells with minimum systemic toxicity in GFP-expressing mice following intraperitoneal injection of CriPs containing Gfp-targeting sgRNA. Furthermore, disruption of a nuclear co-repressor of catabolism, the Nrip1 gene, in white adipocytes by CriPs enhanced adipocyte browning with a marked increase of uncoupling protein 1 (UCP1) expression. Of note, the CriP-mediated Nrip1 deletion did not produce detectable off-target effects. We conclude that CriPs offer an effective Cas9 and sgRNA delivery system for ablating targeted gene products in cultured cells and in vivo, providing a potential therapeutic strategy for metabolic disease
