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.
To evaluate the therapeutic response to uterine artery embolization in 30 patients with leiomyoma using the microspheres Embosoft (Embosoft® - Scitech Medical).
This is an Expanded Access Program to make lenvatinib available to participants with radioiodine-refractory differentiated thyroid cancer in Brazil. Participants who have no other treatment options available, and who, in the opinion and clinical judgment of the treating physician, would benefit from treatment with lenvatinib will be enrolled. This is a multicenter, open-label program consisting of 2 phases: a 28-day pretreatment phase (including screening) and a treatment phase. Treatment will be provided as long as there is a clinical benefit based on tumor assessments performed according to the center's standard of care and the judgment of the participant's treating physician.
Background: Dynamic balance keeps the vertical projection of the center of mass within the base of support while the center of mass moves. The age-related decrease in dynamic balance is a risk factor for falls. Dynamic balance tests are used to predict the risks for falls and eventual falls but the psychometric properties of most tests assessing dynamic balance are unsatisfactory and comprise no actual loss of balance while walking. Objectives: Using beam walking distance as a measure of dynamic balance, we will determine the psychometric properties, lifespan and patient reference values, the relationship with selected 'dynamic balance tests', and the accuracy of beam walking distance to predict falls. Methods: This cross-sectional observational study will examine healthy adults in 7 decades (n=432) at 4 centers. Center 5 will examine patients (n=100) diagnosed with Parkinson's disease, multiple sclerosis, stroke, and balance disorders. At Test 1, all participants will be measured for demographics, medical history, grip and leg strength, short physical performance battery, static balance on a force platform, and dynamic balance using beam walking (4m-long, 4, 8, and 12 cm wide) under single (beam walking only) and dual task conditions (beam walking while concurrently performing an arithmetic task). In addition, cognitive function (global cognition, attention, executive function, processing speed, memory) will be assessed. Patients and healthy participants age 50+ will be additionally measured for fear of falling, history of falls, miniBESTest, functional reach on a force platform, timed up and go, and reactive balance. At Test 2, 7-10 days after Test 1, healthy adults young and age 50+ (n=40) will be re-tested for reliability of beam walking performance. All participants age 50+ will be re-called to report fear of falling and fall history 6 and 12 months after Test 1. Conclusion: The investigators expect to find that beam walking performance vis-à-vis the traditionally used balance outcomes predicts more accurately fall risks and falls.
The aim of this study is to investigate the effect of overnight fasting versus a diurnal fasting (during daily life activities) in females with and without obesity on inflammation, neurotrophins, energy metabolism, mood, food cravings, and appetite sensations. This study will be an acute fasting intervention.
This study evaluates the effects of physical exercise through active videogame in the microcirculation, macrocirculation, cardiorespiratory function and physical fitness in overweight adolescents. For that, they will be randomized into two groups, one being a control group and the other intervention group. The randomization will be made by school. The intervention group will perform the physical exercise through the active video game, three times a week, for 50 minutes, during 8 weeks. Reassessments will be performed before and after the intervention to evaluate the outcome variables.
This is an international, multicentre, parallel-group, randomised, double-blind, placebo controlled, phase II study to evaluate the benefits and risks of using sodium zirconium cyclosilicate (ZS) to initiate and intensify renin angiotensin aldosterone system inhibitor (RAASi) therapy in heart failure patients.
This study evaluates the hypoalgesic effect of the TENS application associated with joint manipulation of the cervical region in healthy individuals. One group had both active treatments, the other group received both placebo treatments, the third and fourth group received only one of the two treatments actively and the other placebo
This study evaluated the differences between normotensive and hypertensive menopausal women in ambulatory and blood pressure variability responses to combined aerobic and resistance exercise.
Adolescents with cerebral palsy (CP) present important limitations for the performance of daily living activities. The aims of the study is to evaluate the feasibility and effects of an intensive goal training protocol for adolescents with CP. He hypothesize that adolescents submitted to the studied protocol will present improvements in performance and satisfaction of prioritized functional goals.
Patients who have shown previous implantation failures, despite transferring good quality and chromosomally normal embryos (diagnosed by PGT-A), could have a displaced Window of Implantation (WOI) and consequently, alterations in their endometrial receptivity. The correction of this displacement can improve the results of the Assisted Reproduction Treatments (ART). The ERA test (Endometrial Receptivity Analysis) evaluates the transcriptomic endometrial profile to determine if the patient's uterus is receptive when the embryo is transferred during an In Vitro Fertilization (IVF) process, and identifies the personalized WOI of the patient. This process is called Personalized Embryo Transfer (pET). The Preimplantation Genetic Test of Aneuploidies or PGT-A (Preimplantation Genetic Testing for Aneuploidy), is currently carried out using Next Generation Sequencing (NGS) and serves to identify chromosomally normal embryos prior to their transfer in an IVF treatment. Aneuploidies are rarely compatible with life or can cause congenital diseases. So, the identification of chromosomally normal embryos, improves the success of reproduction in cases in which infertility is caused by such aneuploidies. Therefore, the aim of this study is to determine, in a randomized and prospective way, the clinical benefit of adding the ERA test to the embryonic aneuploidies test for patients with a PGT-A indication.
