There are about 6461 clinical studies being (or have been) conducted in Russian Federation. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
An interventional prospective randomized clinical trial (RCT) was conducted in parallel groups. The sample size consisted of 30 patients who were randomly assigned to two groups based on the type of surgical intervention. The first group received implants with a sloped edge platform (Dentsply Sirona CIS, ASTRA TECH Implant System, registered in Russia on 21/12/2019, No. РЗН 2015/3214). The second group received implants with bone grafting. The assessment in the postoperative period included evaluating the condition of the soft tissues, bone resorption, number of analgesics, duration of the operation, edema, keratinized mucosa width, implant stability quotient, pain severity, and quality of life.
Sepsis is a critical burden for a healthcare. From 2000 to 2020, the number of publications and clinical studies on the topic of Sepsis and septic shock on the National Library of Medicine resource The National Center for Biotechnology Information has tripled. Sepsis is a life-threatening condition that causes significant pathophysiological changes in the body. Currently, sepsis is understood as organ dysfunction caused by a dysregulatory response of the macroorganism to infection. A special role in this process belongs to the innate and adaptive immune response. Despite the trend towards improving survival rates, mortality in sepsis remains high - about 25%, reaching 60% with the development of septic shock. Extracorporeal therapy, as an adjuvant method of treatment, has been used for more than 30 years, but conducting large randomized studies confirming its effectiveness is associated with a complex of problems, including the extreme heterogeneity of the population of patients with sepsis and septic shock, different etiologies and complex pathogenesis, non-identical pathophysiological pathways of the dominant organ dysfunction in specific time period and degree of its severity. Goal of the study is to evaluate safety and efficiency of combined hemoperfusion and therapeutic plasma exchange in adult patients with septic shock.
The development of acute respiratory and renal failure of COVID-19 patients is associated with an excessive immune response and hyperproduction of anti-inflammatory cytokines, which leads to impaired endothelial function and a dysregulated balance between the coagulation and fibrinolytic systems in the blood. These factors contribute to the development of multi-organ failure, sepsis, and high mortality rates.In the absence of effective etiotropic therapy for COVID-19, it is necessary to search for alternative, pathogenetically based treatment approaches, including extracorporeal methods of homeostasis support. This observational study examines the effect of early hemoperfusion using the Efferon CT device for the treatment of patients with severe forms of COVID-19 after their intubation on a ventilator.

In the modern population, mortality and disability from cardiovascular diseases is predominant and is realized as a major medical and social problem. The study of mechanisms of development of age-related diseases, such as coronary heart disease (CHD), has demonstrated multiple qualitative and quantitative changes of metabolites in biological fluids of the body - blood, in the vascular wall, as well as in the tissues of vital organs. In routine clinical practice only about a dozen metabolic parameters are determined by standard laboratory methods. The proposed approach belongs to a new scientific direction , wich development is aimed at individualization of approaches to risk stratification of cardiovascular diseases and their complications. The data obtained in this project will allow to create a base of medical knowledge about spectral characteristics of blood serum, which most fully reflect the metabolic profile associated with atherosclerosis of coronary arteries. Researchers offer so-called multiplex diagnostics when multiple parameters of a biological object obtained by serum biochemical analysis and optical scattering analysis are used. Recognition of this big data is possible only by methods of mathematical analysis, which can take into account the degree of deviations, their directionality in each point of the spectral characteristic. Until recently, the standard setup for Raman light scattering studies had significant dimensions. The high cost of such installations made it difficult to widely use the method of optical spectroscopy for rapid analysis of medical objects. In recent years, the situation on the market of scientific instrumentation has changed radically, which allowed to significantly reduce and cheapen all components of Raman installations.This simplification and cheapening allows to bring optical research in medicine (optical biopsy) to a new level of use, directly into clinical laboratories. Novelty: This area of research belongs to high-tech and is very little represented in Europe. The prospect of using Surface Enhanced Raman spectroscopy (SERS) to determine subclinical lesions of coronary arteries and for risk stratification of diseases associated with atherosclerosis is quite unique and wasn't explored yet.
The importance of assessing venous congestion in heart failure patients is widely acknowledged, but its study is hampered by the lack of a practical evaluation tool. Venous excess ultrasound score (VExUS) is a promising noninvasive ultrasound-guided modality that can detect and objectify clinically significant organ congestion. VExUS congestion grading score was still not formally validated in patients with AHF, as there is limited data on its clinical application in this group of patients.
This is a single-arm cohort study aimed to evaluate change of arteriovenous fistula volume blood flow / cardiac output ratio in patients with chronic heart failure (NYHA I-II classes) and with preserved ejection fraction as a result of a hemodialysis session after a "long" interdialysis interval.
Chronic heart failure (CHF) is a syndrome complicating heart disease, the prevalence of which has reached epidemic levels. According to global statistics the most common causes of CHF are coronary heart disease (CHD): 26.5%, arterial hypertension (AH):26.2% . The category of patients with CHD complicated by CHF prevails in clinical practice, requiring an optimized approach to determining prognosis in order to improve the effectiveness of therapy. In the literature, this issue has been studied with the use of general clinical, biochemical, instrumental criteria. Nevertheless, the problem of optimized prognosis in patients with CHF remains. Its solution may lie in the study of metabolic parameters of biological media - skin, blood serum by Raman spectroscopy. Skin is an accessible tissue for studying the effects of a wide range of age-dependent noncommunicable diseases, including cardiovascular disease, type 2 diabetes mellitus, and chronic kidney disease. We were one of the first to use skin RS as a method of determining renal dysfunction, a necessary component of chronic kidney disease. However, the applicability of RS/SERS in the diagnosis and prognosis of specific diseases, as well as in the collection of statistical data for this analytical approach, remains an open question . Despite the fact that the method is classified as analytical, it can be used to identify not so much specific chemical molecules as their specific loci, which provide vibrations that change the wavelengths of the scattered spectrum. The resulting spectrum can be presented as a metabolic "portrait" of the disease, with the most informative loci, the combination of which is associated with a negative prognosis. The innovative analytical methods of optical spectroscopy proposed in this project provide new level information about hundreds of molecules and their active centers that have prospects as biomarkers. This study aims to determine the clinical relevance of skin and serum RS in patients with CHF, realized on state-of-the-art instrumentation in a comprehensive patient study setting. The research proposed in this project will contribute to the development of high-tech production of new optical devices for rapid diagnosis and prognosis of a wide range of diseases.
