There are about 197 clinical studies being (or have been) conducted in Kazakhstan. 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.
A survey of people to identify risk factors for osteoporosis, which include age, gender, lifestyle, diet, physical activity, the presence or absence of somatic pathology. Diagnosis of osteoporosis by dual-energy X-ray absorptiometry. Conducting a correlation analysis of the relationship of the data obtained.
Background: Ketosis after bariatric surgery is a metabolic process that occurs when the body breaks down fat for energy because of not getting enough carbohydrates. Insufficient production of ketone bodies reduces the rate of weight loss, and excessive amounts of ketones can lead to ketoacidosis or liver failure in patients with nonalcoholic steatohepatitis (NASH). The investigators hypothesize that weight loss is directly related to calorie intake, and a significant reduction in carbohydrate content leads to increased ketosis and the risk of ketoacidosis. Objectives: The study aimed to compare the incidence of ketoacidosis and liver failure in patients with NASH with different intakes of carbohydrates in the early postoperative period after gastric bypass. In addition, the investigators want to find out how carbohydrate restriction will affect weight loss for up to 1 year.
The goal of this observational study is to develop a Clinical Decision Support System for severe patients with polytrauma. The main questions it aims to answer are: - Is it possible to predict the development of systemic inflammatory response syndrome for the next 24 h after admission? - Is it possible to predict the development of blood loss >25% of blood volume for the next 24 h after admission? - Is it possible to predict the development of acute traumatic coagulopathy for the next 24 h after admission? - Is it possible to predict the development of pneumonia in polytrauma patients? - Is it possible to predict the outcome in polytrauma patients? No intervention is planned for this study.
The goal of this observational study is to evaluate the effectiveness and safety of vibro-acoustic pulmonary therapy (VAPT) in complex therapy for the acute respiratory failure of mixed type I-II stages in comparison with percussion massage in cardiac surgical patients in the early postoperative period.
To evaluate the visual and refractive outcomes after an intraocular lens (IOL) implantation in pediatric eyes with cataract and preexisting corneal astigmatism
The aim of this prospective observational study is to evaluate the effectiveness of the mobile application "Colorectal Leakage App" in the early diagnosis of anastomotic leakage after colorectal surgeries at the National Research Oncology Center in Astana, Kazakhstan. Main Questions: 1. Development, validation, and implementation of the mobile application "Colorectal Leakage App," based on the Dutch Leakage Score. 2. Evaluate the diagnostic effectiveness of the application in detecting anastomotic leakage after colorectal surgeries. 3. Determine the frequency of anastomotic leakage after colorectal surgeries performed in the colorectal surgery sector of the National Research Oncology Center in the Astana city. Participants in the study, individuals aged 18 and above undergoing colorectal surgeries, will be monitored by the mobile application "Colorectal Leakage App" in the postoperative period for early identification of anastomotic leakage.
The goal of this observational study is to learn the effectiveness and safety of the use of Carnitine-Orotate Complex and Biphenyl Dimethyl Dicarboxylate in the pathogenetic therapy of metabolic-associated fatty liver disease (MAFLD)
This study is open to adults who are at least 18 years old and have a body mass index (BMI)bof 27 kg/m2 or more. People can take part if they have cardiovascular or chronic kidney disease. People who have at least 2 health problems related to their weight or risks of cardiovascular disease can participate. Participants must have previously tried to lose weight by changing their diet. The purpose of this study is to find out whether people with overweight or obesity who take a medicine called survodutide (BI 456906) are less or more likely to develop serious cardiovascular problems. It also aims to find out whether health parameters like blood pressure improve. Overweight and obesity are linked to cardiovascular disease. Survodutide is a medicine that is developed to help people with obesity or overweight to lose weight. Participants are divided into 3 groups of almost equal size. 2 groups get different doses of survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Every participant has a 2 in 3 chance of getting survodutide. Participants inject survodutide or placebo under the skin once a week. All participants also receive counselling on diet and physical activity. Participants are in the study for up to 2 years and 3 months. During this time, it is planned that participants visit the study site up to 21 times and attend remote visits by video calls. During these visits, the doctors check participants' cardiovascular and overall health. The results are compared between survodutide and placebo groups. The study staff also takes note of any unwanted effects.
This study aims to evaluate the effectiveness of heparin-conjugated gel for treating ankle joint cartilage lesions compared to the conventional microfracture method. It involves 40 participants aged 18 to 65 with localized cartilage defects (Outerbridge II-IV) in the ankle's talus bone. Participants will be divided into two groups: the main group and the control group. The main group will undergo a two-stage process. Initially, adipose tissue will be collected via lipoaspiration from osteoarthritis patients. This tissue will be used to isolate mesenchymal stem cells (MSCs) and extract growth factors, resulting in a biocomposite hydrogel. In the second stage, arthroscopy will be performed to apply the hydrogel for cartilage treatment. The control group will undergo standard microfracture surgery, a known cartilage repair method. The study's main objective is to compare heparin-conjugated gel treatment to microfracture in terms of cartilage repair and patient outcomes. A 12-month follow-up will assess short-term and potential mid-term effects. Data will be analyzed using Microsoft Excel and Statistica 13.0 for descriptive and comprehensive statistical analysis. Quantitative indicators will be assessed using appropriate tests (Mann-Whitney, Wilcoxon T, χ2) to determine significant differences between groups. The study addresses key questions: Does heparin-conjugated gel offer better cartilage repair, functional improvement, and pain reduction than microfracture? Does the hydrogel approach better preserve joint integrity and slow degeneration? Are there complications with either method? This study combines cellular and surgical components to explore innovative cartilage lesion treatments. Comparing with microfracture and using a thorough follow-up, it aims to enhance cartilage repair techniques and patient outcomes.
