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 determine whether physiotherapy is effective in the treatment of the chronic functional constipation in children.
The purpose of this study is to evaluate the additive effect of dorzolamide/timolol fixed combination in patients undergoing monotherapy with latanoprost.
During myocardial infarction, inflammatory response may negatively influence ventricle wall remodeling as well as endothelium-dependent vasomotor function in the coronary and systemic arterial systems. Statins have been consistently proved to attenuate inflammation and improve endothelial function. In this study, we tested the effect of different doses of statin on inflammatory response and endothelium-dependent vasodilation.
The purpose of this study is to compare propofol associated with fentanyl versus midazolam plus fentanyl for sedation during diagnosis or therapeutic upper gastrointestinal endoscopy (UGE) in cirrhotic patients.
During acute coronary syndromes (ACS), the generation of inflammatory mediators negatively influences arterial wall remodeling and the endothelium-dependent vasomotor function in the coronary and systemic arterial systems. In fact, the intensity of the inflammatory upregulation is strongly related to the incidence of recurrent coronary events. The investigators previously demonstrated that high dose potent statins can rapidly reduce plasma levels of cholesterol-rich lipoproteins and inflammatory activity in subjects during ACS. In addition, such statin treatment attenuates the post-discharge endothelial dysfunction of these patients. By inference, it is plausible to hypothesize that these beneficial effects during ACS may be intensified by an additive lowering of plasma cholesterol through the treatment with ezetimibe. So far, data is unavailable to verify this assumption. In parallel, data from animal models have suggested that both statins and ezetimibe may reduce insulin sensitivity by their effect on cholesterol content and, by this way, on insulin signaling in liver cells. In this context, the present study aims to investigate the role of the addition of ezetimibe upon statin treatment on stress-induced insulin resistance and on the time-course of the inflammatory response during the acute phase of myocardial infarction and its late effect on endothelium-dependent arterial dilation.
Acute renal insufficiency (ARI) represents a frequent and serious complication in patients submitted to cardiac surgery, and is associated with increases in time of hospitalization, costs, morbidity and mortality. Its incidence varies from 3.5% to 31%. The present study aims to evaluate renal function and oxidative stress in patients submitted to revascularization surgery with extracorporeal circulation (ECC), comparing targeted venous anesthesia controlled with propofol and inhalational anesthesia with isoflurane.
Climacterium is marked by hypoestrogenism and it is associated to drastic vasomotors symptoms, genital atrophy and humor alteration. Additionally, these symptoms impair sexual life and life quality. These effects can be counteracted by administration of estrogen therapy. However, estrogen therapy has side effects and isoflavone has been proposed as an estrogen substitute in reposition therapy. The aim of the randomized controlled trial is to evaluate the effects of isoflavone in the sex life assessed by a modified McCoy's sexual questionnaire.
Alzheimer's disease (AD) is an age-related degenerative disorder of the brain, characterized by progressive decline in cognitive function and ability to perform activities of daily living, and ultimately can lead to death due to complications of the disease. AD is thought to be caused by an excess of A-Beta amyloid, a sticky protein in the brain that forms amyloid plaques. Treatments that slow the synthesis or deposition of A-Beta amyloid, or that increase clearance, might be expected to slow the progression of AD. LY2062430 (solanezumab) is a humanized anti-A Beta peptide immunoglobulin G-1 (IgG1) monoclonal antibody being developed for the treatment of AD. The primary hypothesis being tested is that LY2062430 will slow cognitive and functional decline in AD as compared with placebo. Each patient's participation will last approximately 19 months. Patients taking approved AD medications may participate in this study and continue taking these medications during the study.
The purpose of this study is to evaluate the pharmacokinetic interaction of test formulations of candesartan and felodipine in a combination package comparing with the fasting intake of commercial formulations of both Atacand ® and Splendil®
The objective of this study is to verify, through a randomized, single-blind, multicentre, parallel and comparative study, the effectiveness of heparin sodium of porcine origin in patients undergoing heart surgery that require the aid of cardiopulmonary bypass. The effectiveness will be determined through the control of hemostasis during and after surgery, based on the strengths of markers of coagulation trichloroacetic acid (TCA), alpha-tocopherol transfer protein (TTPA), Anti-Xa, heparin bioavailability and excessive loss of blood (bleeding) at the end of the surgery.
