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 primary objective was to evaluate the effect of treatment with evolocumab, compared with placebo, on the risk for cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization, whichever occurs first, in patients with clinically evident cardiovascular disease.
The purpose of this study is to investigate the effects of muscle fatigue in the scapular kinematics of overhead athletes with and without using a kinesio taping technique for facilitating lower trapezius function. The hypothesis is that the taping technique could compensate for the negative effects caused by muscle fatigue in the scapular kinematics of healthy overhead athletes.
This retrospective study comprised patients with cataract, corneal astigmatism, and motivation for spectacle independence. In all cases, a multifocal and monofocal Intraocular Lens was been implanted in the capsular bag. Three months postoperatively, distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity was evaluated. A patient-satisfaction and visual phenomena questionnaire was also been administered.
Two-arm, randomized, prospective, open-label, multi-center, phase III study to compare the efficacy and safety of MEK162 (45 mg BID) versus dacarbazine (1000 mg/m2 IV every 3 weeks) in patients with advanced (Stage IIIC) unresectable or metastatic (Stage IV) NRAS Q61 mutation-positive cutaneous or unknown primary melanoma. The mutation analysis will be performed at a central laboratory. Only those patients with Q61 mutation per central laboratory and meet all eligibility criteria will be randomized. A total of 393 patients will be randomized 2:1 to receive either MEK162 or dacarbazine. Patients will be stratified according to AJCC stage (IIIC, IVM1a, and IVM1b versus IVM1c), ECOG Performance status (0 versus 1) and any prior number of lines of immunotherapy (immunotherapies versus none). This study will use an Interactive Response Technology (IRT). The primary end point of the study is progression-free survival. Key secondary end point is overall survival
The pelvic floor disorders are a major problem in our current society with manifestations of micturition disorders, defecatory problems and sexual dysfunction. The pelvic floor muscles training arouses interest due the few studies on this subject. Studies are being conducted with emphasis on the post-prostatectomy urinary disorders, however, not associated with radiotherapy. The study of the effect of radiotherapy in these muscles is still uncertain. At right, we do not know if the effect of radiation can trigger important anatomical changes that could lead to pelvic floor disorders manifesting clinically as defecatory and urinary disorders. These issues motivate us to research, focusing on the evaluation of these muscles through magnetic nuclear resonance considering that radiation therapy has been increasingly used as a therapeutic option in the treatment of prostate cancer. The primary objective of this is to verify the effect of pelvic floor muscles training (PFMT) tract symptoms (LUTS), anorectal and sexual complaints in men with prostate cancer (PCa) treated with radiotherapy (RT). Secondly, the objective is to evaluate the effect of PFMT in its function and in the severity of urinary incontinence (UI) and evaluate the quality of life. The assessment of the changes occurred by the effect of radiation separately and jointly to the training of the pelvic floor muscles can help us to better understand some of the dysfunctions presented in this sample of patients as well as understanding the effect and the possible contribution of training of these muscles for treatment and/or prevention of these disorders.
The purpose of this study is to evaluate the effect of Saccharomyces boulardii in patients in the waiting list for liver transplant.
The postpartum period represents a stage of the pregnancy-puerperal still rarely addressed scientifically. There are no reports in the literature and concrete enough to elucidate important issues, especially in the field of hypertension and pregnancy. Searches based on current evidence concentrate their focus on the diagnosis of hypertensive disorders and treatment of these diseases maternofetais repercussions. However, the prognosis in the short and long term, as the BP outcome in mothers with severe preeclampsia, the most effective treatment for the control of hypertensive crisis and metabolic and cardiovascular events after two years of termination of pregnancy require further clarification. The main idea for developing this research came from the clinical experience with the use of captopril in Obstetric ICU IMIP. This drug has long been used in postpartum women with severe preeclampsia or chronic hypertension exacerbated by pregnancy for control of hypertensive crisis and keeping pressure levels. Following the technical standards of the institution and during his administration, there were reports of side effects such as dry cough and nausea, beyond the threshold dose of 150mg daily captopril was easily achieved hindering control the use of hypotensive. Alternative therapy, clonidine began to be used in mothers with some restriction on the use of ACE inhibitors and its hypotensive effect for peak pressure was satisfactory. What is not known yet is how long clonidine reduces high blood pressure and how long to leave stabilized compared to the use of captopril. There are no reports in the literature databases, no randomized clinical trials that prove the effectiveness of clonidine for the treatment of hypotensive pressure peaks in this particular group of patients, even in comparison with other classes of antihypertensive drugs, especially captopril, to this purpose. The investigators' primary assumption is that clonidine has better effectiveness in decreasing the frequency of pressure peaks when compared with captopril.
Metabolic disorders and malnutrition are well known and have been reported in patients with chronic liver disease, but the relationship of energy metabolism and changes in nutritional status in patients on the waiting list for liver transplantation are unexplored. The aim of this study was to assess the resting energy expenditure (REE) of these patients, identifying the prevalence of hyper and hypometabolism. In addition, to assess if, malnutrition and clinical variables were associated with REE and metabolic disorders.
The purpose of this study is to assess the safety, tolerability, biomarker, cognitive and clinical efficacy of investigational products in participants with an Alzheimer's disease-causing mutation by determining if treatment with the study drug slows the rate of progression of cognitive/clinical impairment or improves disease-related biomarkers.
Background: Physicians´ lack of knowledge contributes to underuse of insulin and poor glycemic control in adults with diabetes mellitus (DM). Traditional continuing medical education have limited efficacy, so new approaches are required. Objective: We report the design of a trial to assess the educational efficacy of InsuOnline©, a game for education of primary care physicians (PCPs) on initiation and adjustment of insulin for the treatment of DM, which was designed to be: a) educationally adequate; and b) self-motivating and attractive. Methods: A multidisciplinary team, with endocrinologists, experts in medical education, and programmers, was assembled for design and development of InsuOnline©, a serious game which includes game elements and a well-defined, evidence-based curriculum of topics on insulin therapy. The first step of our study will be usability and playability tests, with PCPs and medical students, playing the game on a desktop. After that and further adjusts, we will perform an unblinded randomized controlled trial, with PCPs who work in the city of Londrina, to assess the educational validity of the game. A group of 64 PCPs will play InsuOnline© on the web, and the control group, of 64 PCPs, will underwent traditional teaching activities (lecture and group discussion). Knowledge on how to initiate and adjust insulin will be assessed by a web-based multiple-choice questionnaire, and attitudes regarding diabetes/insulin will be assessed by Diabetes Attitude Scale 3, at 3 time points: before, immediately after, and 6 months after the intervention. Subjects´ general impressions on the interventions will also be assessed by free-text questions. Software logs will be reviewed.
