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 prospective randomized study is to compare the safety and efficacy of two strategies for sedation of critically ill patients submitted to mechanical ventilation: continuous intravenous infusion of dexmedetomidine versus intravenous bolus of midazolam. The two groups will be compared as to the incidence of of delirium, evaluated with the Confusion Assessment Method for ICU (CAM-ICU) and the percentage of time within the target sedation using the Richmond Agitation-Sedation Scale (RAAS).Eligible patients will be 18 years or older intubated and mechanically ventilated for less than 48 hours prior to start of study drug and anticipated ventilation duration of at least 48 hours. Calculated sample size is 146 patients (73 patients in each group)
Previous studies have demonstrated a direct association between blood pressure level and cardiovascular risk. However in patients with heart failure this association is considered controversial. The aim of this study is to evaluate the effect of the reduction of blood pressure in patients with heart failure. The investigators will examine the effects of this intervention over mortality, quality of life, and cardiac function.
It gave a clinical trial which will be included in the 60 infants, aged up to 24 months, diagnosed with congenital's population will be divided by simple randomization into three groups: 20 infants in the intervention group, 20 infants in the control group, not receive the RTA technique and another 20 infants in a placebo group, we just get the support manual therapist for 5 minutes. Initially the data will be collected cardio heart rate, respiratory rate and oxygen saturation. Then the researcher will apply three specific rating scales, based on clinical presentation and behavior of infants. Hypothesis: The RTA improves cardiorespiratory parameters and reduces signs of discomfort and pain of infants with congenital heart acyanogenic.
This double-blind, controlled and randomized study intents to investigate the antidepressive response of rTMS on the elderly population.This is the first neuronavegated pulse intensity corrected study of rTMS in elderly depressed patients.
This is a study to assess long-term safety and efficacy of lersivirine in patients who have completed 96 weeks of treatment with lersivirine in studies A5271015 and A5271022.
This study will further investigate the safety and efficacy of nilotinib in newly diagnosed chronic myeloid leukemia patients in the chronic phase
The purpose of this study is to determine whether GSK2402968 is effective in the treatment of ambulant boys with Duchenne muscular dystrophy resulting from a mutation thought to be corrected by exon 51 skipping.
The purpose of this study is to determine acute effect the transctutaneous electrical nerve stimulation in sympathetic and parassympathetic system in individuals with heart failure.
The primary objective was to demonstrate the effect of teriflunomide, in comparison to placebo, on frequency of Multiple Sclerosis (MS) relapses in patients with relapsing forms of MS who are treated with Interferon-beta (IFN-beta). The secondary objectives were: - Assess the effect of teriflunomide, in comparison to placebo, when added to IFN-beta on: - Disease activity as measured by brain Magnetic Resonance Imaging (MRI) - Disability progression - Burden of disease and disease progression as measured by brain MRI - Evaluate the safety and tolerability of teriflunomide when added to IFN-beta therapy - Assess the pharmacokinetics of teriflunomide in use in addition to baseline IFN-beta therapy - Assess associations between variations in genes and clinical outcomes (safety and efficacy) - Assess other measures of efficacy of teriflunomide such as fatigue and health-related quality of life - Assess measures of health economics (hospitalization due to relapse, including the length of stay and any admission to intensive care unit)
Considering the effects of the cholinergic system on the drug reward and self-administration mechanisms, acetylcholine (Ach) may play an important role on cocaine dependence process. Then the present study aims to evaluate biperiden efficacy (a cholinergic antagonist) in attenuate compulsion, one o the main symptoms of the drug dependence.
