This study is two-center, prospective, randomized, open-label, controlled, investigator-sponsored study that aims to investigate the efficacy of low-dose colchicine in preventing recurrent stroke in the patients with acute atherothrombotic minor-to-moderate ischemic stroke during hospitalization.
The goal of this clinical trial is to propose for implementation and evaluate the effectiveness of xenon sedation for the relief of psychoemotional stress disorder before the operation of refractive laser vision correction patients with high anxiety and stress instability who underwent xenon analgosedation before refractive laser vision correction. The main question[s] it aims to answer are: 1. To develop a method of xenon sedation in patients with a high level of psychoemotional stress before surgery - refractive laser vision correction. 2. To evaluate the effect of inhaled xenon anesthesia in a sub-narcotic dose on the duration of surgery, satisfaction of surgeons and patients with anesthesia, the level of postoperative pain in patients in comparison with anxiolytics. The following will be studied: the level of preoperative anxiety, the dynamics of glycemia and blood cortisol levels, heart rate variability, electrical microamplitudes of the ECG signal, the anti-stress and analgesic effect of xenon. If there is a comparison group: the researchers will compare [the group with xenon sedation and the control group] to see if there is [an anti-stress effect of xenon in patients before laser vision correction].
We assume that the frequency of gastrojejunostomy ulcers after MGB-OAGB is associated with the peculiarities of the side-to-side gastrojejunostomy (GJS) formation, which is currently the "gold standard" for this procedure. The geometry of such anastomosis leads to the formation of a narrow strip of the gastric wall between two stapler lines (between the suture from the 2nd cassette during the formation of the "small ventricle" and directly from the suture from the cassette during the GJS formation). Perhaps this section of the stomach wall is prone to ischemia, which can certainly increase the risk of ulcer formation. It is also possible that a zone with impaired blood supply may also form in the "blind pocket" above the anastomosis. When forming a Hand-Sewn GJS of the end-to-side type, ischemia zones do not occur. The anastomosis has a more physiological geometry, there is no conflict between the lines of stapled sutures. Thus, we put forward the assumption that a serious risk factor for the development of a GJS ulcer was eliminated when switching to a completely manual technique for the GJS formation when performing MGB-OAGB. The study is aimed at the compare the incidence of GJS ulcers during MGB-OAGB, depending on the techniques of anastomosis formation.
The modern strategy of therapy of high-risk neuroblastoma, stage 4, consists of three phases - induction, consolidation and post- consolidation. Still current approaches demonstrates insufficient levels of ORR (overall response rate), OS (overall survival) and EFS (event free survival). NB-HR-2023 (neuroblastoma high risk) protocol aimed to investigate tolerability and toxicity and potential improvement of ORR, OS and EFS by overcoming of tumor heterogeneous drug resistance using the synergistic interaction of cytostatic and immunobiological agents in the induction. Protocol include the combination of standard chemotherapy (N5 and N6) with anti-GD2 MAB, which is potentially expected to improve outcomes in patients with high-risk neuroblastoma and ganglioneuroblastoma, 4th stage older 18 months. Currently, treatment with combinations of cytostatics with immunobiological agents is limited due to the risk of complications, which, nevertheless, is controlled with proper monitoring and concomitant therapy. Still no data about use of combination of standard chemotherapy (N5 and N6) with ch14.18/CHO MAB (dinutuximab beta) in induction in primary patients with neuroblastoma. Prospective, interventional trial include patients with neuroblastoma and ganglioneuroblastoma, 4th stage of the high-risk group older 18 months, who will receive combination of standard induction chemotherapy (N5 and N6) with anti-GD2 MAB. Consolidation and post consolidation chemotherapy courses are not the subjects for analysis. Patients with high-risk neuroblastoma and ganglioneuroblastoma, stage 4, older 18 months who receive combination of standard induction chemotherapy (N5 and N6) with anti-GD2 MAB at the Dmitry Rogachev National Medical Research Center Of Pediatric Hematology, Oncology and Immunology Delayed surgery (if needed) will be done after the 4th or 6th course of induction therapy and stem cells apheresis after the 2nd-5th course of induction therapy.
Prospective cohort research to study the state of oxygen metabolism, reserve capabilities of cardiovascular and respiratory systems in patients with breast cancer to create a program of prevention and rehabilitation of lung damage in the process of complex treatment of the disease. The aim of the study is to study the dynamics of oxygen metabolism and reserve capabilities of cardiovascular and respiratory systems in the process of complex treatment of breast neoplasias. Objectives of the study: 1. Explore the dynamics of pulmonary ventilation and gas exchange disorders in patients with breast cancer in the course of radiation therapy 2. Establish an algorithm for risk stratification of post-radiation disorders of pulmonary ventilation and gas exchange in patients with breast cancer. 3. Analyze the prognostic significance of cardiopulmonary exercise testing in assessing the cardiotoxic effect of chemo- and radiation therapy in patients with breast cancer. 4. Analyze the influence of post-radiation disorders of pulmonary ventilation and gas exchange on the quality of life and psycho-emotional status of patients with breast cancer. 5. Develop a fundamental basis for the program of prevention and rehabilitation of post-radiation lung damage in patients with breast neoplasias based on the study of individual parameters of oxygen metabolism and reserve capabilities of cardiovascular and respiratory systems. All participants go through 5-week radiation therapy in standard protocol, will have investigation of their lung functioning by spirography and assessment of pulmonary diffusion capacity, cardiopulmonary stress tests and CT-scan on the lungs before radiotherapy course. Researchers will analyze such parameters as stage of the disease, surgery type, all patient's medications, complications, nutritional status, psychological status.
The aim of this study is to evaluate the efficacy and safety of contrast-free magnetic resonance angiography (MRA) for deep inferior epigastric perforator flap planning. The investigators propose to perform a non-contrast MRA to achieve the following extremely important objectives: to avoid radiation exposure, minimize the risk of potentially harmful effects of contrast agents, and reduce the cost of the study.The investigators assume that the use of non-contrast MRA following our protocol including certain patient's positioning, a special pulse scanning sequence and perforators' projection method is effective and allows mapping of perforators without injecting a potential harmful contrast agent.
