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.
The purpose of this study is to evaluate treatment-free remission after imatinib discontinuation in patients with chronic myeloid leukemia with deep molecular response. Before discontinuation, patients will receive pioglitazone associated with imatinib during 3 months.
Introdution: The Kangaroo Mother Care is a perinatal care model for preterm and low weight newborn. The Kangaroo Position is the main feature of this method. The infant should be lightly dressed, in prone position and upright against the torax of the parents. Researches provides evidence that the Kangaroo Position induces an increase in myoelectric activity of preterm newborn. However, it is unknown how long the newborn should remain in the kangaroo Position so that ocurr changes in electromyographic. An increase in electromyographic activity was observed after 24 hours or more of submission to the Position Kangaroo, however period lower of submission to the Position Kangaroo have not been evaluated yet. Also unknown are the physiological mechanisms that cause this muscle response. One hypothesis would be the increase in temperature caused by skin to skin contact which could improve circulation in small vessels with direct influence on the infusion and nutrition of muscle tissue. Objective: Evaluate the immediate effect of Kangaroo position in the electromyographic activity and microcirculation of preterm newborn. Method: It will be a randomized and controlled trial from August 2016 to February 2017 with newborn preterm admitted at the Kangaroo Unit, IMIP. Newborns eligible according to the inclusion and exclusion criteria will be randomized into two groups: Kangaroo Group (experimental group) and Not Kangaroo Group (control group). The data of the electromyographic activity and the microcirculatory parameters will be assessed and recorded in three stages: before the Kangaroo position, one and three hours after of continuous submission in the Kangaroo Position (for the group of cases) and before the Kangaroo position, one and four after the three assessments (for the control group). In the control group, the preterm newborns will be not submitted to Kangaroo position until the completion of the last and third evaluation. The acquisition of the electromyographic signal will be conducted through an equipment electromyography Miotool 400® brand (Miotec Equipamentos Biomédicos - Brasil). To assess microcirculation will be used for the white light spectroscopy method through the drive moorVMS-OXY®. The project was submitted and approved by Ethics Committee for Research on Human Beings of IMIP (52381915.5.0000.5201). This study is part of a anchor project approved by Conselho Nacional de Desenvolvimento Científico e Tecnológico- CNPq (process 458163/2014-7).
This trial is globally conducted. The aim of this trial is to investigate Efficacy and Safety of Oral Semaglutide Using a Flexible Dose Adjustment Based on Clinical Evaluation versus Sitagliptin in Subjects with Type 2 Diabetes Mellitus.
It is known that laughter can bring benefits in terms of physiological and psychological parameters, in addition to improving the individual's quality of life. However, the literature is still scarce as to the existence of studies investigating the effects of a comedy film specifically in hemodynamics.
This parallel, randomized clinical trial will include 120 participants. They will be allocated to a sodium restriction educational intervention or usual care groups. The educational intervention will be planned based on the DSRQ application and sessions will be conducted once a month for the period of six months. Both spot urine collection to estimate sodium intake and the DSRQ will be applied at the baseline, in the eighth week and at the end of the follow-up. Blood sample and 24-hour ambulatory blood pressure monitoring (ABPM) will be conducted at the beginning and at the end of the follow-up. Anthropometric measurements, blood pressure measurement and 24-hour food recall will be collected during follow-up.
Cardiovascular disease (CVD) is considered the main cause of mortality in the western world. There are many factors that contribute to the onset and progression of cardiovascular disease, including hypertension. Hypertension is a multi-factorial condition that includes nutritional disorders in its causality line. It is believed that advanced glycation end-products (AGEs) is one of the pathophysiological causes that explain the occurrence of high blood pressure in diabetic patients. This study has the role of describing the protocol of a randomized clinical trial aiming to evaluate changes in serum levels of end products of advanced glycation after an intervention for eating habit changes in hypertensive individuals. The investigators designed a randomized clinical trial, with non-blinded assessment of outcomes. Participants will be recruited from the outpatient clinic for hypertension of a public hospital in Porto Alegre, aged from 40 to 80 years old and without diabetes. Hypertension is defined as systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg, or antihypertensive medication use. Participants will be assigned to one of two groups. The intervention group will receive monthly educational intervention sessions for low salt diet, high in fruits and vegetables, and low in processed foods for a period of 6 months. Besides these, the intervention group will receive a standard telephone interview every two weeks to motivate them to follow the diet. The control group will receive the usual counseling for low sodium diet in monthly appointment with a dietitian, following the hypertension care clinic protocol. This study aims to investigate if there are significant changes in serum levels of advanced glycation end products, after the nutritional intervention with diet guidance in fruits, vegetables, low in sodium and processed foods in hypertensive patients because several studies have shown that less processed food rich in antioxidants with low sodium content, play an important role in reducing levels of AGEs which are precursors of vascular inflammation and progression of cardiovascular diseases.
The purpose of the study is to develop a prognostic index model for the rare disease of mycosis fungoides and sezary syndrome. This will be done by collecting standardized clinical data at various institutions. The investigators hope this will enable the identification of low- and high-risk groups for survival in order to improve patient care and outcome.
The aim of this study is evaluate a software developed for alternative communication designed for people with speech difficulties. The software was executed by 30 volunteers using mobile devices that helped to play the scenarios simulated of communication situations.
Background: Depression is a usual comorbid event associated to chronic diseases, such as hypertension and diabetes, constituting an important public health problem, with negative consequences for patients' quality of life and self-care, as well as for compliance with medical treatment. In low and middle income countries depression is often unrecognized and untreated, and there is a lack of human resources to treat depression and other mental problems in these health care systems. Aim: The present study aims to test a 6 week low-intensity psychological intervention (CONEMO) delivered via an applicative for smartphones for people with depressive symptoms and co-morbid diabetes and/or hypertension recruited in primary health care units, in São Paulo (Brazil).
The Purpose of this study is to characterize the single and multiple-dose pharmacokinetic (PK) and pharmacokinetic/pharmacodynamic (PK/ PD) profiles after oral rivaroxaban therapy administered to pediatric participants 2 to 8 years of age with single ventricle physiology who have completed the Fontan procedure within 4 months prior to enrollment (Part A) and to evaluate the safety and efficacy of rivaroxaban, administered twice daily (exposure matched to rivaroxaban 10 milligram [mg] once daily in adults) compared to acetylsalicylic acid (ASA), given once daily (approximately 5 milligram per kilogram [mg/kg]) for thromboprophylaxis in pediatric participants 2 to 8 years of age with single ventricle physiology who have completed the Fontan procedure within 4 months prior to enrollment.
