EVEROLIMUS IN DE NOVO RENAL TRANSPLANT RECIPIENTS

Survival of renal transplants and renal transplants recipients has improved greatly last years, but long-term graft survival remains unchanged. Nephrotoxicity of calcineurin inhibitors is one of the main factors of late renal allograft disfunction. Everolimus, new proliferation signal inhibitor, can facilitate minimization cyclosporine A exposure and has antineoplastic activity. The paper reviews literature dates regarding to clinical aspects of everolimus use in de novo renal transplant recipients

The role of digital consciousness in change management

The article deals with the problems of change management in the new conditions of superfragility of the BANI-world. Interpretations of the concepts of “transcendental thinking”, “digital consciousness”, “immersiveness” are given. The prerequisites substantiating the idea that transcendental thinking needs to be cultivated in the organisation in order to achieve effective management flexibility are presented. The latter is formed in the broader context of the digital consciousness organisational culture, without which it is impossible to set up the organisation’s staff for a positive perception of immersive management practices and the digital technologies productive use. Barriers to the transformation of organisational processes have been identified. It has been shown that the digital transformation of the organisation increases the resistance on the part of the staff by digital resistance plane, when aversion to any change correlates with a lack of ­understanding of digital opportunities. The relationship between the conceptual methodologies of digital consciousness and metacognition and the effectiveness of the formation of a change management strategy has been established

Digital consciousness as a factor of human capital formation in integration processes

The article studies problems of reintegration of social spaces in the conditions of new reality. The concepts of “reintegration”, “digital consciousness” and “human capital” have been interpreted. The concept of reintegration process based on the multiplicative effct of resulting sum of cognitive, axiological, and organizational vectors of social space reassembly on the basis of public support for its digital transformation has been presented. The paper presents assumptions justifying the idea that achieving effctive reintegration is primarily associated with economic development of a territory so it is necessary to form human capital on the basis of digital consciousness. In the modern world, digital consciousness is becoming a dominant cognitive factor as digital technologies are increasingly penetrating our lives and changing the way people interact. However, developing digital consciousness requires continuous learning and skill development. It can be achieved through professional training, self-education, and participation in projects related to digital transformation. Thus, digital consciousness can be considered as a factor ofhuman capital growth that can help people adapt to changing labor market conditions and work successfully in digital economy

Association of Blood MicroRNA Expression and Polymorphisms with Cognitive and Biomarker Changes in Older Adults

BackgroundIdentifying individuals before the onset of overt symptoms is key in the prevention of Alzheimer's disease (AD).ObjkectivesInvestigate the use of miRNA as early blood-biomarker of cognitive decline in older adults.DesignCross-sectional.SettingTwo observational cohorts (CHARIOT-PRO, Alzheimer's Disease Neuroimaging Initiative (ADNI)).Participants830 individuals without overt clinical symptoms from CHARIOT-PRO and 812 individuals from ADNI.MeasurementsqPCR analysis of a prioritised set of 38 miRNAs in the blood of individuals from CHARIOT-PRO, followed by a brain-specific functional enrichment analysis for the significant miRNAs. In ADNI, genetic association analysis for polymorphisms within the significant miRNAs' genes and CSF levels of phosphorylated-tau, total-tau, amyloid-& beta;42, soluble-TREM2 and BACE1 activity using whole genome sequencing data. Post-hoc analysis using multi-omics datasets.ResultsSix miRNAs (hsa-miR-128-3p, hsa-miR-144-5p, hsa-miR-146a-5p, hsa-miR-26a-5p, hsa-miR-29c-3p and hsa-miR-363-3p) were downregulated in the blood of individuals with low cognitive performance on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The pathway enrichment analysis indicated involvement of apoptosis and inflammation, relevant in early AD stages. Polymorphisms within genes encoding for hsa-miR-29c-3p and hsa-miR-146a-5p were associated with CSF levels of amyloid-& beta;42, soluble-TREM2 and BACE1 activity, and 21 variants were eQTL for hippocampal MIR29C expression.Conclusionssix miRNAs may serve as potential blood biomarker of subclinical cognitive deficits in AD. Polymorphisms within these miRNAs suggest a possible interplay between the amyloid cascade and microglial activation at preclinical stages of AD

Structure of litter macrofauna communities in poplar plantations in an urban ecosystem in Ukraine

The litter macrofauna of 8 plantations of Populus italica (Du Roi) Moench, P. deltoides Marsh. and P. alba L. was studied in the city of Dnipro. The invertebrates were taken by manual sifting of litter from experimental plots of 8 m2. The total number of litter macrofauna in the poplar plantations varied from 8 to 187 specimen/m2, on average 53 specimen/m2. The greatest variety of species was obtained from a white poplar plantation with common hop and an elm-poplar plantation with bare soil and Amorpha fruticosa L. bushes (15 and 9 species correspondingly). The ma ximum readings on the Shannon–Weaver diversity index come from the abovementioned areas (3.2 and 2.9 bits respectively). The highest number of zoophages (40%) was obtained from the white poplar plantation with common hop. There was great consistency in the species composition across the plots, with the same 60 species (more than 50% of the total number of species of litter macrofauna recorded in the study) being found in 7 out of the 8 study plots. The share of species rare for any given ecosystem exceeded 10% in only 2 out of the 8 plantations studied. The dominant group in the size structure of the litter macrofauna of the poplar plantations (44–96%) was invertebrates of 4–7 mm length. In 5 out of 8 poplar plantations no species over 15 mm in length were found. This indicates the degraded size structures of the litter macrofauna communities. In taxonomic structure the dominant groups were Formicidae, Pulmonata, Porcellionidae, Lygaeidae, Julidae, Silphidae, Araneae, Carabidae, Staphylinidae. The results obtained indicate the low variety and degradation of the trophic and size structure of the litter macrofauna of these urban poplar plantations, which are subject to lack of moisture. The litter macrofauna of 8 plantations of Populus italica (Du Roi) Moench, P. deltoides Marsh. and P. alba L. was studied in the city of Dnipro.

Фармакоэкономическое исследование применения эверолимуса для иммуносупрессивной терапии у de novo реципиентов почечного трансплантата в России

Currently, patients after kidney transplantation can receive mycophenolate mofetil (MPM), mycophenolic acid (MPA), cyclosporine (CSA) and tacrolimus (TAC) through the Federal High-cost Nosologies Program (VZN) in Russia. Use of everolimus (EVL) in combination with a reduced dose of calcineurin inhibitors has some advantages over the current practice of immunosuppressive therapy that is financed through VZN.Aim: to conduct a comprehensive pharmacoeconomic research of using EVL for immunosuppressive therapy of adult de novokidney transplantation recipients in comparison with the current immunosuppressive therapy practice that is covered by the VZN Program in the Russian Federation.Materials and methods. According to the latest clinical data, effectiveness of immunosuppressive therapy schemes based on EVL and MPA is comparable, which allows to use ‘cost minimization’ method for pharmacoeconomic research. We also performed budget impact analysis of the VZN Program expenditures for a period of 2020–2022.Results. The three-year medication costs of using EVL-based immunosuppressive scheme were 502,785 RUB, which was 508,493 RUB (50.3%) less than medication costs of using MPA-based schemes that are covered by the VZN Program in current practice. The inclusion of EVL to the VZN Program will reduce its costs by 90 million RUB during the first year (2020), by 181 million RUB – during the second year (2021), and by 262 million RUB during the third year (2022). In three years VZN Program costs could be reduced by 533 million RUB (48.6%).Conclusion. Use of EVL is a cost-saving approach for immunosuppressive therapy of adult de novo kidney transplant recipients, compared to MPA-based schemes, that are covered by the VZN Program in current practice in Russia.На сегодняшний день за счет средств федеральной программы высокозатратных нозологий (ВЗН) пациенты после трансплантации почки могут получать микофенолата мофетил (МФФ), микофеноловую кислоту (МФК), циклоспорин (ЦСА) и такролимус (ТАК). Применение эверолимуса (ЭВЛ) в комбинации со сниженной дозой ингибиторов кальциневрина обладает рядом преимуществ по сравнению с использованием МФФ или МФК в комбинации с полной дозой ЦСА или ТАК.Целью настоящей работы является проведение комплексного фармакоэкономического исследования применения ЭВЛ для иммуносупрессивной терапии у взрослых de novo реципиентов почечного трансплантата по сравнению с текущей практикой иммуносупрессивной терапии, оплачиваемой за счет средств программы ВЗН, в условиях Российской Федерации.Материалы и методы. Для проведения исследования был выбран метод «минимизация затрат», так как, согласно опубликованным клиническим исследованиям, эффективность схем иммуносупрессивной терапии на основе ЭВЛ и МФК является сопоставимой. Расходы учитывались за три года. Дополнительно был проведен анализ влияния на бюджет программы ВЗН на период 2020–2022 гг.Результаты. Расходы на лекарственную терапию при использовании схемы на основе ЭВЛ за три года составляют 502 785 руб., что на 508 493 руб. (50,3%) меньше по сравнению с расходами на лекарственную терапию при использовании схем, финансируемых за счет средств программы ВЗН в текущей практике. Включение ЭВЛ в программу ВЗН позволит сократить ее расходы на 91 млн руб. в первый год после включения (2020), на 181 млн руб. – во второй год (2021) и на 262 млн рублей– в третий год (2022). Всего за период трех лет расходы программы ВЗН могут быть уменьшены на 533 млн руб., или на 48,6%.Заключение. Применение схем на основе ЭВЛ является ресурсосберегающим методом ведения de novo реципиентов почечного трансплантата по сравнению со схемами, финансируемыми за счет средств программы ВЗН в текущей практике
