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.
The study is aimed at assessing the role of the activity of markers of endothelial dysfunction (cytotoxic malonic aldehyde (MDA), angiotensin II, endothelial nitric oxide synthase (NO), endothelin-1, prostacyclin) in the systemic circulation in patients with lower extremity atherosclerotic arterial occlusive disease undergoing open reconstructive interventions.
Carotid endarterectomy (CEA) is a well-established procedure for preventing ischemic brain damage. Stenosis of the precerebral vessels are often combined with arterial hypertension. In recent decades, many works have appeared that indicate that the course of arterial hypertension (AH) changes after CEA. However, it remains unknown how this is related to the choice of surgical tactics.
Obstructive jaundice is observed in 10-80 % of gallstone disease cases. The conventional tactics for the management of patients with obstructive jaundice is to remove biliary hypertension by using endoscopic or minimally invasive methods. The final surgical treatment is performed after jaundice reduction and normalization of hepatic functions. We suppose that the administration of the drug Remaxol (Inosine + Meglumine + Methionine + Nicotinamide + Succinic acid) during the perioperative period shortens jaundice duration and decreases the complications rate.
The study should evaluate distribution of [99mTc]Tc-G3-(G3S)3C in patients with primary HER2-positive and HER2-negative breast cancer
The study should evaluate distribution of [123I] I-(HE)3-G3 in patients with primary HER2-positive and HER2-negative breast cancer
The purpose of the study: To develop a differentiated management strategy for obese children based on the analysis of the relationship between their clinical, metabolic, immunological and microbiological status Research objectives: 1. To give a clinical and metabolic characteristic of a group of obese children (age, gender, degree of obesity, body mass index SDS, the presence of complications of obesity, clinical signs of metabolic syndrome, laboratory markers: AlT, AsT, cholesterol, high and low density lipoproteins, uric acid, insulin, leptin). 2. To study the immunological indicators of inflammation in obese children (the level of highly sensitive CRP, proinflammatory cytokines - IL-1b, IL-6, IL-10, IL-18, TNF-α). 3. To assess the state of the intestinal microbiota in obese children by MALDI-TOF mass spectrometry. 4. To analyze the relationship of clinical-metabolic, immunological and microbiological status in obese children and identify markers associated with metabolic syndrome and the formation of complications. Materials and methods: At stage 1, it is planned to conduct a cohort study in a group of school-age children with obesity (n=120) with the study of their clinical, metabolic, immunological and microbiological status. The control group will consist of healthy children of the appropriate age who are not overweight (n= 20). Stage 2 of the study consists in prospective observation of children of the examined group who do not have complications and clinical manifestations of metabolic syndrome for 6 months against the background of standard therapeutic measures (diet, lifestyle correction, physical activity) and repeated clinical and laboratory examination.
Patients with cardiac pathology and arrhythmias including those who have indications for pacemakers implantation will be included in the study. We will determine the influence of pacemaker implantation with the localization of the ventricular electrode in the top of the right ventricle or the middle third of the right ventricle according to echocardiographic and electrocardiographic parameters, congestive heart failure progression, patients' quality of life and follow-up therapy of patients with identified myocardial fibrosis with existing pacemaker. Study of changes in echocardiography, electrocardiography, myocardial fibrosis markers, the quality of life of patients will allow to choose the most optimal localization of the ventricular electrode during implantation of the permanent pacemakers system in order to improve the quality of life of the patients.
The study attempts to quantify the relative risks for acute postoperative pain, complications rate, chronic postoperative pain (CPIP) and recurrence rate after different methods of repair of groin, umbilical and incisional hernia depending on surgical technique, mesh type and fixation suture material. For this purpose the investigators will analyze data from the Kalinigrad Hernia Registry (KHR).
The aim of the study is to assess the effect of oral probiotics containing Streptococcus salivarius M18 on gingivitis and oral hygiene in young adults.
Study population will consist of HRD+ (BRCAm +/- positive genomic instability score according to used test system) OC with available medical history. It is estimated that approximately 400 patients will be enrolled in approximately 25 sites. Demographic and clinical characteristics, treatment approaches and outcomes in HRD+ patients with high-grade epithelial ovarian, primary peritoneal, and/or fallopian tube cancer will be collected at baseline and on prospective visits.
