Development of internal control methodology by using statistical methods of variability assessment of material flow business processes

Variability or instability is one of the key features of any process, including business processes of material flow internal control. Variability is a characteristic of all natural systems and technical processes. The objects which properties can be characterized via certain parameters arise at the output of any process. The article discloses the feasibility of using the statistical methods in the internal control system of business entities; in this case the focus is on the method of identifying the causes of variability using control charts of various types (Shewhart control charts) as a prime tool. The view points regarding variability of famous academic economists who researched the business process management issues are also considered. Authors’ classification of business process variation on types of material flow internal control with the allocation of controlled and uncontrolled variation is taken as the basis of the proposed application. The method of using control charts in estimating the efficiency of material flow internal control business processes is described in detail.peer-reviewe

THE RUSSIAN REGISTRY OF RITUXIMAB. ANALYSIS OF THE EFFICIENCY OF THERAPY AND THE FUNCTIONAL STATEOF PATIENTS WITH RHEUMATOID ARTHRITIS

Objective: To evaluate the functional status of patients with rheumatoid arthritis (RA) receiving two courses of rituximab (RTМ) therapy and its efficiency from the Russian registrys data. Subjects and methods. The analysis covered 269 patients receiving 1 or 2 courses of RT therapy, their clinical follow-up schedules and quality of life (QL) questionnaires were filled in before drug administration and at 8, 16, and 24 weeks of a follow-up: 220 and 49 patients received 1 and 2 courses of RT therapy, respectively. The DAS28 index was used to evaluate disease activity; the patients functional status was assessed according to the Health Assessment Questionnaire (HAQ). Results. The patients' mean age was 46.5311.79 years; the disease duration was 9.806.87 years; disease activity scale (DAS28) scores were 6.501.06; the majority of patients had significant functional disorders estimated at 1.90 [1.37-2.38] scores according to the HAQ; 78% patients had extra-articular manifestations; rheumatoid factor was detected in 82.9%; the patients received more than 2 basic antiinflammatory drugs on average; 33.5% took TNF-р inhibitors. After the first course of therapy at 24 weeks of the follow-up, there was a gradual decline in DAS28 from 6.491.05 to 4.091.32 scores (p < 0.000001, ANOVA). A significant reduction in serum C-reactive protein was achieved during the first course of therapy just at 2 weeks of the follow-up. A decrease in DAS28 to і1.2 was seen in 79.9 of the patients after the first course at 24 weeks of the follow-up and in 85.7% after the second course. 13% of patients achieved drug-induced remission (DAS2

Роль лабораторных биомаркеров в мониторинге и прогнозировании эффективности терапии ревматических заболеваний генно-инженерными биологическими препаратами

Significant progress in treating immunoinflammatory rheumatic diseases (RD) is related to the design of a novel family of drugs, genetically engineered (GE) drugs. Molecular and cellular biomarkers (antibodies, indicators of acute inflammation, cytokines, chemokines, growth factors, endothelial activation markers, immunoglobulins, cryoglobulins, T- and B-cell subpopulations, products of bone and cartilage metabolism, genetic and metabolic markers) that allow one to conduct immunological monitoring and prediction of the effectiveness of RD therapy using tumor necrosis factor α inhibitors (infliximab, adalimumab, golimumab, etanercept), anti-B-cell drugs (rituximab, belimumab), interleukin-6 receptor antagonist (tocilizumab), and T-cell costimulation blocker (abatacept) have been detected in blood, synovial fluid, urine, and bioptates of the affected tissues. In addition to the conventional uniplex immunodiagnostics techniques, multiplex analysis of marker, which is based on genetic, transcriptomic and proteomic technologies using DNA and protein microarrays, polymerase chain reaction, and flow cytometry, is becoming increasingly widespread. The search for and validation of immunological predictors of the effective response to GE drug therapy make it possible to optimize and reduce the cost of therapy using these drugs in future.Значительный прогресс в лечении иммуновоспалительных ревматических заболеваний (РЗ) связан с разработкой нового класса лекарственных средств – генно-инженерных биологических препаратов (ГИБП). В настоящее время в крови, синовиальной жидкости, моче и биоптатах пораженных тканей выявлены молекулярные и клеточные биомаркеры (антитела, показатели острой фазы воспаления, цитокины, хемокины, факторы роста, маркеры активации эндотелия, иммуноглобулины, криоглобулины, субпопуляции Т- и В-лимфоцитов, продукты метаболизма костной и хрящевой ткани, генетические, метаболические маркеры), позволяющие осуществлять иммунологический мониторинг и прогнозирование эффективности терапии РЗ ингибиторами фактора некроза опухоли α (инфликсимаб, адалимумаб, голимумаб, этанерцепт), анти-В-клеточными препаратами (ритуксимаб, белимумаб), антагонистом рецептора интерлейкина 6 (тоцилизумаб), блокатором костимуляции Т-клеток (абатацепт). Наряду с традиционными униплексными методами иммунодиагностики все шире применяется мультиплексный анализ биомаркеров, основанный на генетических, транскриптомных и протеомных технологиях с использованием ДНК- и белковых микрочипов, полимеразной цепной реакции, проточной цитометрии. Поиск и валидация иммунологических предикторов эффективного ответа на терапию ГИБП создает предпосылки для оптимизации и снижения стоимости лечения этими препаратами

Использование международного индекса для оценки активности системной склеродермии

Up to now, it is difficult to determine systemic scleroderma (SSD) activity because of the lack of validated tools to estimate changes in the pathological process. Attempts have been made to develop unified activity assessing methods for many years. The indices proposed by the European SSD Group are most popular today. This paper gives the results of using this index in a cohort of Russian patients.Определение активности системной склеродермии (ССД) до настоящего времени затруднено из-за отсутствия валидированных инструментов для оценки изменений патологического процесса. В течение многих лет предпринимаются попытки создания унифицированных методов оценки активности заболевания. Наиболее популярными на сегодняшний день являются индексы, предложенные европейской группой по изучению ССД. В статье представлены результаты использования этого индекса у когорты российских пациентов
