Karst hazard assessment in the design of the main gas pipeline (South Yakutia)

The paper represents the description of the zonal and regional geological factors of geoengineering conditions which characterize the territory in South Yakutia crossed by the designed main gas pipeline. Cryogenic processes and karst are considered to be the most dangerous hazards for gas pipeline maintenance. Karst hazard assessment of the gas pipeline section made in the course of the research has involved a complex of geological methods: geoengineering, geophysical, hydrogeological, and mapping. Sections prone to karst development have been identified. The authors have suggested the measures to protect potentially hazardous sections and to ensure timely informing on sinkhole collapses

Features of Semantic Translation of Collective Historical Memory

The article was submitted 15.09.2022; approved after reviewing 30.09.2022; accepted for publication 15.10.2022.Статья поступила в редакцию 15.09.2022; одобрена после рецензирования 30.09.2022; принята к публикации 15.10.2022.The article is devoted to the methodological problem of the interaction of individual and collective in the phenomenon of historical memory. The identification of specific features of collective memory, the nature and dynamics of collective memories allows, on the one hand, to conceptualize collective memory, to substantiate its ontological status, on the other, to reveal the features of the mechanisms of collective memories. The article analyzes such features of collective memory as conventionality, tradition, repeatability, selectivity, etc. The thesis about the ambivalent nature of collective historical memory as a process is defended.Статья посвящена методологической проблеме взаимодействия индивидуального и коллективного в феномене исторической памяти. Выявление специфических особенностей коллективной памяти, природы и динамики коллективных воспоминаний позволяет, с одной стороны, концептуализировать коллективную память, обосновывать ее онтологический статус, с другой — раскрывать особенности механизмов работы коллективных воспоминаний. В статье проведен анализ таких особенностей коллективной памяти, как конвенциональность, традирование, повторяемость, селективность и т. д. Отстаивается тезис об амбивалентной природе коллективной исторической памяти как процесса

Клинико-экономическая оценка целесообразности применения квадритерапии у пациентов с хронической сердечной недостаточностью со сниженной фракцией выброса в медицинских организациях Московской области

Objective: assessment of feasibility of using four-component drug therapy for patients with chronic heart failure with reduced ejection fraction (CHFrEF) in medical organizations of the Moscow Region (MR).Material and methods. Clinical and economic analysis of combined standard therapy with angiotensin-converting enzyme inhibitors, beta-blockers, and mineralocorticoid-receptor antagonists in combination with dapagliflozin (a sodium-glucose cotransporter 2) in the treatment of patients with CHFrEF was carried out. The effectiveness criteria were the number of prevented cardiovascular (CV) deaths and the percentage of the contribution to the achievement of the target indicator to reduce mortality from circulatory diseases within the framework of the regional program “Health care development”. In order to determine the economic feasibility of quadritherapy, direct medical costs for the implemented technology were calculated, the cost of one prevented CV death was determined based on the values of the number needed to treat (NNT) indicator. Budget impact analysis was performed which allowed to build two analytical models. Results. It was shown that the use of quadritherapy can significantly contribute to achieving the target indicator by additionally preventing 512 CV deaths by 2024, which will make it possible to fulfill up to 74.74% of the indicator set by the MR state program “Health care of the Moscow Region” (451.4 persons per 100 thousand population). Using quadruple therapy in 1000 target patients during the first year will prevent 11 CV deaths (NNT 90 persons). The cost of one prevented CV death was 3.860 million rubles. The budget impact analysis made it possible to determine that when CHF patients switch from standard treatment regimens to quadritherapy, including in combination with a drug of the angiotensin/neprilysin receptor inhibitor group (valsartan + sacubitril), this will entail an increase in healthcare system budget costs by 18.8%.Conclusion. The results demonstrate that the standard therapy in combination with the innovative drug dapagliflozin leads to a proven reduction in mortality from circulatory diseases. This technology is a cost-effective approach to organizing medical care for adult patients with CHFrEF on the MR territory.Цель: оценка целесообразности применения четырехкомпонентной лекарственной терапии для лечения пациентов с хронической сердечной недостаточностью со сниженной фракцией выброса (ХСНнФВ) в медицинских организациях Московской области (МО).Материал и методы. Проведен клинико-экономический анализ комбинированной стандартной терапии лекарственными препаратами классов ингибиторов ангиотензинпревращающего фермента, бета-адреноблокаторов, антагонистов минералокортикоидных рецепторов в комплексе с препаратом группы ингибитора натрий-глюкозного котранспортера 2-го типа дапаглифлозин при лечении пациентов с ХСНнФВ. В качестве критериев эффективности выступали показатели количества предотвращенных сердечно-сосудистых (СС) смертей и процент вклада в достижение целевого показателя по снижению смертности от болезней системы кровообращения в рамках региональной программы «Развитие здравоохранения» МО. В целях определения экономической целесообразности применения квадритерапии рассчитаны прямые медицинские затраты на внедряемую технологию, определена стоимость одной предотвращенной СС-смерти на основании значений показателя числа больных, которых необходимо пролечить (англ. number needed to treat, NNT). Проведен анализ влияния на бюджет, в рамках которого построены две аналитические модели.Результаты. Показано, что применение квадритерапии способно внести существенный вклад в достижение целевого показателя путем дополнительного предотвращения 512 СС-смертей к 2024 г., что позволит выполнить до 74,74% от индикатора, установленного государственной программой МО «Здравоохранение Подмосковья» (451,4 чел. на 100 тыс. населения). Применение четырехкомпонентной терапии у 1 тыс. целевых пациентов в течение первого года позволит предотвратить 11 СС-смертей (NNT 90 чел.). Стоимость одной предотвращенной СС-смерти составила 3,860 млн руб. Анализ влияния на бюджет позволил определить, что при переходе пациентов с ХСН со стандартных схем лечения на квадритерапию, в т.ч. в комбинации с препаратом группы ингибиторов рецепторов ангиотензина/неприлизина (валсартан + сакубитрил), повлечет за собой рост затрат бюджета системы здравоохранения на 18,8%. Заключение. Полученные результаты демонстрируют, что применение стандартной терапии в комбинации с инновационным препаратом дапаглифлозин ведет к доказанному снижению смертности населения от болезней системы кровообращения. Данная технология является экономически целесообразным подходом к организации медицинской помощи взрослым пациентам с ХСНнФВ на территории МО

Fixed and separate combination of solifenacin and tamsulosin in urinary disorders associated with benign prostatic hyperplasia: a choice based on price and value comparison

Objective. To determine the consequences of the use of a fi xed combination of solifenacin and tamsulosin in patients whom recommended the prescription of these drugs. Methods. Analysis of prices of drugs solifenacin + tamsulosin controlled release (Vasomni), solifenacin (Vesicare), tamsulosin controlled release (Omnic Okas) and tamsulosin modifi ed-release (several registered trade names of the drug) conducted on the basis of information from several sources: 1 — the register of maximum ex-works prices of manufacturers of vital and essential medicines, 2 — data on average prices in pharmacies of Moscow (as of 15.02.2018), 3 — weighted average prices of public procurement for 2018 according to the monitoring of the pharmaceutical market. To determine the points of relative value of drugs, a survey of experts was conducted: 1 — to determine the values of the criteria for the drugs under consideration — urologists; 2 — to determine the weight of the criteria — persons involved in the decision-making on the selection and purchase of drugs. Results. We found that the cost of the equivalent course dose of Vesomni was on 40-42 % lower than the combination of drugs Vesicar and Omnik Okas. Compared with the non-fi xed combination of solifenacin with tamsulosin in a drug form with modifi ed release, no signifi cant diff erences in price levels were found. At the same time, the relative value of a fi xed combination is 5-6 percentage points higher compared to non-fi xed combinations, mainly due to ease of use. Conclusion. Use of a fi xed combination of solifenacin + tamsulosin can lead to budget savings with an increase in the level of relative value

Using reference materials of blast furnace slag, steelmaking slag, converter slag and fused fluxes when developing a procedure for analysis of slag-forming mixtures using inductively coupled plasma atomic emission spectrometry

Introduction. Slag-forming mixtures play an important role in obtaining metal without non-metallic inclusions. Required properties of slag-forming mixtures (SFMs) directly depend on their chemical composition, that is why control of individual component content in a mixture is an important stage in the technological chain of metallurgical production. At the present time, it is a common practice to use inductively coupled plasma atomic emission spectrometry (ICP-AES for analyzing SFMs, requiring sample preparation by alloying with alkali fluxes, which makes it impossible to determine potassium and sodium oxides in a sample. That is why it is necessary to work out a procedure for simultaneous determination of calcium, silicon, magnesium, aluminium, potassium, and sodium oxides by the method of ICP-AES, which would include quantitative transferring of all components into a solution. For that purpose, it is suggested to use microwave digestion of samples in autoclaves.The purpose was to develop a procedure for simultaneous determination of specified components of SFMs using ICP-AES after transferring the sample into a solution in an autoclave under conditions of microwave heating, and to certify it reference materials of slag and fluxes.Materials and methods. Compositional analysis of slag-forming mixtures was conducted using an atomic emission spectrometer with inductively coupled plasma «iCAP 6500 Duo»; sample digestion was conducted with the use of the microwave system «ETHOS PLUS». The following brands of SFMs were chosen as research objects: Melubir 9563 and Accutherm ST-SP/235AL4D; AlsifluxGS-C7; SRCP015, SRCP173P. For calibrating the spectrometer and controlling correctness of determining the specified components, the following reference materials were used: reference materials of blast furnace slag, steelmaking slag, converter slag, and fused fluxes, which have close chemical composition.Research results. An ICP-AES analysis procedure has been developed for calibrating the spectrometer and controlling correctness of determining CaO, SiO2 , MgO, Al2 O3 , K2 O, Na2 O in reference materials of blast furnace slag, steelmaking slag, converter slag and fused fluxes, which allows to establish target components of SFMs quickly and reliably
