There are about 6420 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 goal of this interventional is to assess advantages of the ultrasound examination of the lungs in the early postoperative period in cardiac surgical patients after heart surgeries requiring cardiopulmonary bypass. Evaluation of pulmonary complications and outcomes during mid-term follow-up, as well as comparison of ultrasound examination and traditional roentgenologic methods (X-ray examination and CT of the chest) will be performed. The main question[s] it aims to answer are: - Is ultrasound examination of the lungs a more specific and sensitive method in identification of early postoperative pulmonary complications after on-pump cardiac surgical procedures, in comparison with traditional X-ray methods. - Does early identification of interstitial pulmonary edema (based on number of visualised B-lines in the early postoperative period), influences mid-term outcomes in this cohort of patients Participants will undergo ultrasound examination of the lungs on postoperative day 1, 3, 5 and 7 after heart surgery. Based on ultrasound findings and degree of interstitial pulmonary edema, medical (diuretics, anti-inflammatory, e.t.c) therapy will be modified. Researchers will compare this group of patients with control group, in which ultrasound examination will be performed in the same time frames, but no changes in medical management based on ultrasound findings will be made to see if timely administered medical therapy, based on ultrasound findings, can significantly improve symptoms, hospital lengths of stay and outcomes of this patients.
Objective: to evaluate the efficacy and safety of the non-immunogenic recombinant staphylokinase with its single bolus administration in comparison with placebo in normotensive patients with intermediate high-risk pulmonary embolism (PE)
This clinical trial will investigate nano fat grafting as a method for treating critical limb ischemia. The method involves the collection of adipose tissue under tumescent anesthesia through a separate incision in the anterior abdominal wall, followed by preparation and injection of nano fat into the tissues of the foot and leg without additional drug therapy. The novelty of this method lies in the use of autologous stem cells and growth factors, differing from current treatments like neovasculgen, which is a plasmid DNA-based treatment. The trial aims to assess the safety and effectiveness of nano fat grafting, including pain relief, the frequency of intraoperative complications, increased distance of pain-free walking, limb preservation, and mortality rates. The trial will involve patients with diagnosed occlusive lesions of the femoral-popliteal-tibial segment and chronic ischemia of III-IV degree according to Fontaine and 5-6 categories according to Rutherford, excluding those with contraindications for surgical intervention on the femoral-popliteal-tibial segment, chronic heart failure of III-IV NYHA class, severe liver or kidney failure, among others. The study design includes preoperative examinations, hospital phase activities including the surgery and post-operative assessments, and follow-up visits at 6 and 12 months post-operation to evaluate the method's safety, complications, and effectiveness based on various parameters like pain, trophic disturbances, and limb ischemia severity. Statistical methods will involve quantitative data presented as mean ± standard deviation, with qualitative traits compared using the Chi-square test or Fisher's exact test. The planned patient number is 40, aiming to demonstrate the effectiveness and safety of nano fat grafting for critical limb ischemia treatment compared to current treatments.
This is a prospective study on the safety and effectiveness of radiofrequency ablation in patients with desmoid tumors. In the study group, all patients after radiofrequency ablation of the tumor after 1 month will be evaluated using MRI and CT studies and, if solid components of the tumor are detected, repeated surgical treatment is performed followed by active monitoring after 1 month. In the absence of a solid component, the effect is estimated by the volume of the necrotic process and monitored in dynamics every 3 months.
The purpose of this study is to measure the efficacy and safety of baxdrostat in Asian participants with uHTN or rHTN. The main objective is to compare the difference in SBP change from baseline at Week 12 of treatment between participants receiving 2 mg baxdrostat or 1 mg baxdrostat tablets and participants receiving placebo tablets.
There are few studies in the literature that have evaluated the effects of using percutaneous stimulation of the auricular branch of the vagus nerve for sports purposes (to accelerate recovery after physical exertion). It has been demonstrated that tVNS in athletes improved the rate of heart rate recovery, reduced lactic acid levels in blood plasma, reduced pain, reduced overtraining syndrome and fatigue levels.
Esophageal and esophagogastric junction cancer is still one of the main health care issue and esophagectomy with lymph node dissection is the only chance to be cure. However, esophagectomy for esophageal cancer is a complex procedure which carries high risk of morbidity rate of 24% and a mortality rate of 2% to 5.6%, respectively There is a need to study the differences of 90-day postoperative morbidity and mortality in different clinics and centers of the Russian Federation.
Gastric cancer is still one of the main health care issue and gastrectomy with lymph node dissection is the only chance to be cure. Trials show that the postoperative course differs significantly between eastern and western centers, as well as between clinics within Russian Federation. Postoperative 30-day postoperative mortality after gastric cancer surgery ranges from 1% to 5%, and postoperative complication rates range from 10% to 40%. To improve the quality of further studies and recommendations for standardization of surgical treatment of gastric cancer and its complications, there is a need to study the differences in 90-day postoperative morbidity and mortality in different clinics and centers of the Russian Federation.
Dental pain, a common issue in stomatology, requires a multifaceted treatment approach. This study explores the efficacy of combining Ibuprofen with curcumin and liquorice root supplements for managing postoperative dental pain. Curcumin, known for its antioxidant and anti-inflammatory properties, along with liquorice root, may enhance pain relief beyond conventional NSAIDs like Ibuprofen. This randomized, double-blind, placebo-controlled trial aims to evaluate the safety and effectiveness of this combination therapy in adults undergoing the removal of impacted third molars. Participants, aged 18-85, were divided into groups receiving different doses of Ibuprofen and curcumin with liquorice root, compared to a control group receiving Ibuprofen and placebo. The primary outcome is the sum of pain intensity differences over 8 hours, with secondary outcomes including total pain relief and the occurrence of any adverse events. The anticipated sample size, considering a 20% dropout rate, is 264 participants, ensuring the study is powered to detect significant differences in pain management efficacy.
This randomized, double-blind, placebo-controlled trial evaluates the efficacy of a zinc, selenium, and L-tyrosine supplement in preventing thyrotoxicosis among adults aged 18-85 with elevated TPOAb levels and the r25191G/A SEPP1 polymorphism. The study excludes those with thyroid disease, pregnant/breastfeeding women, and individuals allergic to the supplement. Key endpoints include changes in thyroid antibodies and hormones over a 6-month period. With an estimated sample size of 150 participants per group, accounting for a 20% dropout rate, the trial seeks to demonstrate the supplement's potential in reducing thyrotoxicosis risk through a genetically-informed approach.
