There are about 10004 clinical studies being (or have been) conducted in Brazil. 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.
Systemic arterial hypertension is one of major risk factors to development of target organ damage that culminate in cardiovascular diseases such as acute myocardial infarction and stroke. Sodium intake is related with elevation of arterial blood pressure due to rise of cardiac output and of arterial stiffness and it can be estimated by daily sodium excreted in urine 24h. Ambulatory Blood Pressure Monitoring can be used to obtain peripheral and central hemodynamic parameters [arterial stiffness parameters - central blood pressure, pulse wave velocity and augmentation index]. Applanation tonometry also can be used to check same central hemodynamic parameters. Both methods provide us important informations about the patients clinical conditions and help us to infer their prognosis. Therefore, this protocol aims measure the central hemodynamic parameters in hypertensive patients, controlled or resistant, and evaluate their sodium urinary excretion. The hypothesis is the resistant hypertensive patients have parameters higher than controlled hypertensive patients.
The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of CC-99282 alone and in combination with anti-lymphoma agents in participants with relapsed or refractory non-Hodgkin's lymphomas.
Thiazide diuretics have demonstrated favorable blood pressure lowering efficacy, safety profile and low cost, but it is still unclear what are the equivalence of doses of their more common agents, chlorthalidone and hydrochlorothiazide. Besides, concernments about adverse metabolic effects such as hypokalemia, hyperglycemia and hyperlipidemia do exist, which may be attenuated with the concomitant administration of a potassium-sparing diuretic, such as amiloride. In addition to control adverse effects of thiazides, amiloride could offer an additional blood pressure lowering effect, but the efficacy of different doses was not fully established. This study aims to investigate the blood pressure lowering efficacy of chlorthalidone and hydrochlorothiazide, in combination with amiloride in different doses, for the initial management in patients with primary hypertension.
The standard treatment for palmar hyperhidrosis is bilateral sequential thoracic sympathectomy. High rates of compensatory sweating due to the surgical procedure are described in the literature. In the search for a reduction in this side effect, it is possible that unilateral sympathectomy in the dominant side obtains acceptable results and leads to less compensatory sweating with improvement of the quality of life. The aim of this study it to compare the intensity of compensatory sweating due to the standard treatment, that is, bilateral sequential videothoracoscopic sympathectomy in relation to unilateral thoracic sympathectomy on the dominant side.
Objective this study is to analyze the effects of an intervention protocol with neuromuscular electrical stimulation in the vastus medialis obliquus and gluteus medius (GM) associated with exercises on electromyographic activity, muscle performance, self-reported functionality and pain of women with patellofemoral pain.
SASH Trial is a multicenter, prospective, open and randomized 1:1 study. The aim of this study is to evaluate the efficacy of TDM-621(Three-D Matrix- 621) (PuraStat®) on hemostasis of ascending aortic surgery. The TDM-621 is a topic hemostatic product. When in contact with blood it allowed to cover the sutures improving the hemostasis. The hypothesis is that the use of TDM-621 may reduce bleeding and the need for blood transfusion of patients undergoing ascending aortic surgeries. It will include 200 consecutive patients randomized to receive TDM-621 or regular procedure, performed in 5 different centers.
The purpose of this trial is to pragmatically investigate whether participation of people with diabetes and prediabetes in an Exercise and Lifestyle Education Program (i.e., exercise and education classes) results in better functional capacity, disease-related knowledge and behavior, and cardiometabolic health parameters when compared to Exercise Program (i.e., exercise class only). In addition, the effects of these interventions will be evaluated on other outcomes: program adherence, satisfaction with the program, quality of life, diet quality, depression, and morbidity associated with diabetes in the 6-month follow-up.
The purpose of this study is to investigate the effect of digital cognitive training in the functionality of older adults with Mild Cognitive Impairment.
Today in Brazil, 6.9% of the population has Diabetes Mellitus 2 (DM2). In the world, there are about 422 million people with DM2. It is a chronic disease of the endocrine system, accounts for 90 to 95% of cases of DM2 and is characterized by defects in insulin action and secretion. Its main cause is linked to obesity and insulin resistance. Obesity is a chronic, multifactorial disease - environmental, nutritional and genetic factors - characterized by excessive accumulation of body fat, and is reaching epidemic proportions, more than 100 million children and 600 million adults worldwide. The number of obese people in Brazil reaches 17.9% of the population. Rates of obesity and DM2 have increased in the last decades, both diseases being associated with inflammation and specific alterations in the intestinal microbiota. Thus, studies show that the use of probiotics may be associated with reduced body weight and reduced glucose in the bloodstream. Probiotics are living microorganisms that, when administered in suitable dosages, confer benefits to the health of the host. In addition, studies show the relationship of the intestinal microbiota and the emergence of various diseases and demonstrate that probiotics can control inflammatory processes, metabolic dysfunctions, normalization of stress-induced behaviors, regulation of the hypothalamic-pituitary-adrenal axis and neuropsychiatric disorders. Thus, the importance of investigating the ingestion of probiotics in relation to anthropometry, biochemical profile and anxiety in diabetic and overweight individuals with cardiopathy are justified. It is a randomized, double-blind, controlled clinical trial. The study will last 3 months and will occur with 74 adult individuals (between 20 and 60 years) of the SUS outpatient clinic of the Institute of Cardiology of Porto Alegre - RS, of both sexes, with BMI above 25 m² / kg. and less than 40 m² / kg, divided into 2 groups and 37 individuals per group. These patients were: Group A (intervention: n = 37): patient received 1 sachet per day of probiotics Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus lactis, Bifidobacterium lactis and Bifidobacterium bifidum for 90 days and Group B (placebo; n = 37): microcrystalline cellulose, lactose, pregelatinized maize starch. Probiotics will contain a dose of 109 CFU in each strain. The excipients used will be: microcrystalline cellulose.
The aim of this study is to compare en masse (EM) and two-step anterior teeth retraction (TSR) evaluated by means of three-dimensional images superimposition. Thirty-two adult patients with bimaxillary protrusion planed for treatment with four first premolar extractions will be enrolled. All patients will be randomly allocated in a 1:1 ratio to either EM (n=16) group or the TSR (n=16) group. Cone bean computed tomography will be taken before and after anterior retraction. A blind observer will construct separate 3D models for maxillary and mandibular surfaces using the anterior cranial fossa to register models of before and after space closing. Quantitative assessment of posterior anchorage loss and amount of anterior teeth retraction are the main outcomes. The secondary outcomes are the inclination of the molars, canines and incisors.
