Medico-economic evaluation of providing hospital care at cerebral stroke (literature review)

This article presents the literature review dedicated to the assessment of economical damage caused by vascular cer-ebropathies and covers a wide range of problems including medico-economical assessment, grounding of technologies and medical action programs. The review gives monetary evaluation of costs for delivery of health care at cerebral stroke that testifies to the extremely high financial burden for health care system including treatment, medico-social rehabilitation and secondary prevention. The data on the annual costs value and the structure of average expenses related to the accomplished case of medical treatment at cerebral stroke, transitory ischemic attacks, postinsult vascular dementia determined by the disease gravity and length of hospital stay. Also the review presents the indices that describe the effectiveness of the delivery of health care: level and terms of hospitalizing of patients with cerebral stroke to the neurology unit, accessibility of appliance of neuroimaging and some other modern and high-technology methods of diagnostics and treatment

IntroductionMonoclonal antibody light chain proteins secreted by clonal plasma cells cause tissue damage due to amyloid deposition and other mechanisms. The unique protein sequence associated with each case contributes to the diversity of clinical features observed in patients. Extensive work has characterized many light chains associated with multiple myeloma, light chain amyloidosis and other disorders, which we have collected in the publicly accessible database, AL-Base. However, light chain sequence diversity makes it difficult to determine the contribution of specific amino acid changes to pathology. Sequences of light chains associated with multiple myeloma provide a useful comparison to study mechanisms of light chain aggregation, but relatively few monoclonal sequences have been determined. Therefore, we sought to identify complete light chain sequences from existing high throughput sequencing data.MethodsWe developed a computational approach using the MiXCR suite of tools to extract complete rearranged IGVL-IGJL sequences from untargeted RNA sequencing data. This method was applied to whole-transcriptome RNA sequencing data from 766 newly diagnosed patients in the Multiple Myeloma Research Foundation CoMMpass study.ResultsMonoclonal IGVL-IGJL sequences were defined as those where >50% of assigned IGK or IGL reads from each sample mapped to a unique sequence. Clonal light chain sequences were identified in 705/766 samples from the CoMMpass study. Of these, 685 sequences covered the complete IGVL-IGJL region. The identity of the assigned sequences is consistent with their associated clinical data and with partial sequences previously determined from the same cohort of samples. Sequences have been deposited in AL-Base.DiscussionOur method allows routine identification of clonal antibody sequences from RNA sequencing data collected for gene expression studies. The sequences identified represent, to our knowledge, the largest collection of multiple myeloma-associated light chains reported to date. This work substantially increases the number of monoclonal light chains known to be associated with non-amyloid plasma cell disorders and will facilitate studies of light chain pathology.</p
