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 aim of this study was to evaluate the efficacy of the Clostridium difficile vaccine to prevent primary symptomatic C. difficile infection (CDI) in participants at risk for CDI where there is a substantial unmet medical need. Primary objective: - To assess the efficacy of the C. difficile vaccine in preventing the onset of symptomatic primary CDI confirmed by polymerase chain reaction (PCR) in adult participants aged >= 50 years who are at risk for CDI and have received at least 1 injection. Secondary Objectives: Efficacy: - To assess prevention of symptomatic PCR-confirmed primary CDI cases after 3 injections administered at 0, 7, and 30 days. - To assess prevention of symptomatic PCR-confirmed primary CDI cases after completion of at least 2 injections. Immunogenicity: - To describe the immunogenicity to toxin A and toxin B at specific time points in a subset of participant and in participants with CDI at Day 0 and Day 60. Safety: - To describe the safety profile of all participants who received at least 1 injection.
The purpose oh the study is to determine the usefulness of anti-Mullerian hormone (AMH) to identify women at risk of excessive and poor response in controlled ovarian stimulation (COS) for in vitro fertilization (IVF), and the clinical impact of applying individualized COS strategies in these subsets of patients.
When the glaucoma filtering surgery failures (intraocular pressure rises again), the options is start to use the hypotensive eye drops again (medical treatment). However, in some cases (encapsulated blebs), there is a simple surgical revision that can revival the primary failure surgery. It calls transconjunctival needling revision. In this study, the investigators compare the efficacy of this revision versus medical treatment in 12-month follow up in eyes with encapsulated blebs.
The purpose of this study is to verify the effects of low frequency functional electrical stimulation in heart failure patients hospitalized for treatment of the syndrome.
Migraine has been described as one of the most common neurological diseases, with high social and economic impact. Despite the high prevalence, the pathophysiology of migraine is still unknown, several studies have been developed in order to advance the understanding of the pathophysiological mechanisms of the disease which are not yet entirely elucidated. The aim of this study is to observe the effects of transcranial direct current stimulation (tDCS), applied in the visual cortex, on neurophysiological and clinical measures (frequency, intensity, duration of attacks and severity of pain) in migraine patients.
The objective of this work will be compare the effects of two balance training programs, one Nintendo Wii Fit-based and the other traditionally-based without the use of a gaming system, on the (1) motor function, (2) cognition, (3) balance and (4) gait in chronic stroke patients. It is a prospective, single blinded, randomized clinical trial performed at Center of Research of the courses of Speech Therapy, Physical Therapy and Occupational Therapy of São Paulo University. Forty patients will be randomly assigned in control and experimental group, 20 each one.
We aim to evaluate the safety and efficacy of repetitive transcranial magnetic stimulation (rTMS) for apathy treatment in patients with Alzheimer's disease (AD). We hypothesize that rTMS will be superior to placebo to reduce apathy symptoms and severity in patients with AD.
The aim of the present study is verify glycated hemoglobin (HbA1c) and HOMA behavior in pregnant women with gestational diabetes or chronic hypertension after an aerobic training in cycle-ergometer. The sample is composed by 64 pregnant and sedentary women, 20 weeks' pregnant. Two experimental groups (gestational diabetes and chronic hypertension, n = 16 each) will perform a low-intensity aerobic training in cycle-ergometer, three times/week, for 45 minutes each session. Two control groups (gestational diabetes and chronic hypertension, n = 16 each) will perform an unique session/week of relaxation and stretching. Outcomes: first ventilatory threshold, HbA1c,HOMA, type of delivery, weight and height of the newborn.
The purpose of this study is to investigate the long-term safety and any side effects of baricitinib in participants who have completed a previous baricitinib rheumatoid arthritis study. The study provides 7 years of additional treatment with baricitinib.
Ureteral stones may be silent in 5.3% of patients. The goal of this study was to prospectively evaluate the impact of a silent ureteral stone on renal function.
