Knowledge and attitudes towards disability in Moldova: A qualitative study of young people's views.

BACKGROUND: People with disabilities in the Republic of Moldova continue to experience considerable discrimination and social exclusion. The Moldovan government recently affirmed their commitment to promote community integration. However, there remains limited evidence to facilitate understanding of these issues, and barriers to the integrative process. OBJECTIVE: This study explored the knowledge and attitudes towards disability of young people within Moldova. METHODS: A qualitative approach was adopted and 3 semi-structured focus group interviews were conducted with schoolchildren (n = 12), aged 13-15 years. These interviews focussed on different aspects of disability, and community integration. Pictorial and written vignettes were used to stimulate discussion. The interviews were conducted and recorded in Romanian, and were subsequently translated into English to facilitate thematic data analysis. RESULTS: Identified themes included: (1) Knowledge and understanding of disability. The young people's knowledge was limited and framed by the medical model of disability; (2) Attitudes towards community integration. A bias against long-term care institutions, but differing views regarding integration; (3) Perceptions of barriers to community integration: (i) Cultural barriers. Negative, even hostile attitudes towards disability; (ii) Policy barriers. Poor support services; and (iii) Physical barriers. Ongoing issues regarding accessibility. CONCLUSIONS: People with disabilities in Moldova experience negative cultural attitudes linked to an outdated conception of disability itself. There are inadequate community support services and infrastructure which act as barriers to inclusion. At present, there can be limited interaction and participation of people with disabilities within local communities, and so few opportunities to refute persistent stereotypes and stigma surrounding disability.

Tracking spending among commercially insured beneficiaries using a distributed data model.

OBJECTIVES: To explore the feasibility of using a distributed data model for ongoing reporting of local healthcare spending, specifically to investigate the contribution of utilization and pricing to geographic variation and trends in reimbursements for commercially insured beneficiaries younger than 65 years. STUDY DESIGN: Retrospective descriptive analysis. METHODS: Commercial claims were obtained for beneficiaries in 5 states for the years 2008 to 2010 using a distributed data model. Claims were aggregated to the hospital service area (HSA) level and healthcare utilization was quantified using a novel, National Quality Forum-endorsed measure that is independent of price and allows for the calculation of resource use across all services in standardized units. We examined trends in utilization, prices, and reimbursements over time. To examine geographic variation, we mapped resource use by HSA in the 3 states from which we had data from multiple insurers. We calculated the correlation between commercial and Medicare reimbursements and utilization. Medicare claims were obtained from the Dartmouth Atlas. RESULTS: We found that much of the recent growth in reimbursements for the commercially insured from 2008 to 2010 was due to increases in prices, particularly for outpatient services. As in the Medicare population, resource use by this population varied by HSA. While overall resource use patterns in the commercially insured did not mirror those among Medicare beneficiaries, we observed a strong correlation in inpatient hospital use. CONCLUSIONS: This research demonstrates the feasibility and value of public reporting of standardized area-level utilization and price data using a distributed data model to understand variation and trends in reimbursements.

SMN-dependent intrinsic defects in Schwann cells in mouse models of spinal muscular atrophy.

Low levels of survival of motor neuron (SMN) protein lead to spinal muscular atrophy (SMA). The major pathological hallmark of SMA is a loss of lower motor neurons from spinal cord and peripheral nerve. However, recent studies have revealed pathological changes in other cells and tissues of the neuromuscular system. Here, we demonstrate intrinsic, SMN-dependent defects in Schwann cells in SMA. Myelination in intercostal nerves was perturbed at early- and late-symptomatic stages of disease in two mouse models of SMA. Similarly, maturation of axo-glial interactions at paranodes was disrupted in SMA mice. In contrast, myelination of motor axons in the corticospinal tract of the spinal cord occurred normally. Schwann cells isolated from SMA mice had significantly reduced levels of SMN and failed to express key myelin proteins following differentiation, likely due to perturbations in protein translation and/or stability rather than transcriptional defects. Myelin protein expression was restored in SMA Schwann cells following transfection with an SMN construct. Co-cultures of healthy neurons with diseased Schwann cells revealed deficient myelination, suggestive of intrinsic defects in Schwann cells, as well as reduced neurite stability. Alongside myelination defects, SMA Schwann cells failed to express normal levels of key extracellular matrix proteins, including laminin α2. We conclude that Schwann cells require high levels of SMN protein for their normal development and function in vivo, with reduced levels of SMN resulting in myelination defects, delayed maturation of axo-glial interactions and abnormal composition of extracellular matrix in peripheral nerve.
