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 assess the efficacy of ice popsicle compared with water at room temperature in relieving thirst in the immediate postoperative period . The hypothesis of the study is that ice has 20% greater efficacy than water to relieve thirst in the immediate postoperative period.
About 90 % of vascular symptoms affecting the lower limbs consist of venous diseases. Its highest incidence occurs from the second decade of life, affecting significantly the economically active population. Chronic Venous Insufficiency treatment aims to relieve symptoms, treat and prevent complications, prevent recurrences and provide cosmetic satisfaction with minimal side effects. It's current treatment includes some classic postural measures (leg elevation), elastic stockings and bandages compression therapy and possible medication (phlebotonics). The results in the medium and long term are unfavorable, since a large number of patients do not get better or evolves with recurrence of symptoms. Nowadays many, no prospective , not randomized , international studies have shown favorable results with endovascular treatment of obstruction in the iliac vein territory in patients with advanced Chronic Venous Insufficiency . The purpose of this prospective, double-blinded randomized study is to evaluate the results obtained with endovascular treatment, through the use of angioplasty and stenting in this group of patients when compared with clinical treatment .
The purpose of this study is to test if Symbicort® (budesonide/formoterol) Turbuhaler® is effective in treating asthma when used 'as needed' in patients with milder asthma. The efficacy of Symbicort® 'as needed' will be compared with: 1) terbutaline Turbuhaler® 'as needed' and with 2) Pulmicort (budesonide) Turbuhaler® twice daily plus terbutaline Turbuhaler® 'as needed'.
The Pamela Study is a clinical trial carried out during pregnancy to assess the potential effects of physical activity during pregnancy among previously inactive women. The trial is nested into a birth cohort of more than 4000 dyads (mother-child) and took place in Pelotas, Brazil.
Postoperative respiratory failure, particularly after surgery under general anesthesia, adds to the morbidity and mortality of surgical patients. Anesthesiologists inconsistently use positive end-expiratory pressure (PEEP) and recruitment maneuvers in the hope that this may improve oxygenation and protect against postoperative pulmonary complications (PPCs), especially in obese patients. While anesthesiologists tend to use PEEP higher than in non-obese patients. While it is uncertain whether a strategy that uses higher levels of PEEP with recruitment maneuvers truly prevents PPCs in these patients, use of higher levels of PEEP with recruitment maneuvers could compromise intra-operative hemodynamics. The investigators aim to compare a ventilation strategy using higher levels of PEEP with recruitment maneuvers with one using lower levels of PEEP without recruitment maneuvers in obese patients at an intermediate-to-high risk for PPCs. We hypothesize that an intra-operative ventilation strategy using higher levels of PEEP and recruitment maneuvers, as compared to ventilation with lower levels of PEEP without recruitment maneuvers, prevents PPCs in obese patients at an intermediate-to-high risk for PPC.
In this study, HIV-infected patients with poor recovery of CD4+ T cells and successful viral control after treatment with antiretroviral therapy will be enrolled to receive once a day Lactobcillus casei Shirota or placebo in a double-blind, randomized fashion. Immune parameters will be monitored for 12 weeks in both arms. The main outcome is CD4+ T cell recovery. Secondary outcomes will include NK cells and T cells immune parameters.
Tobacco addiction is treatable with behavioral and pharmacological means, but results are often less than optimal. Transcranial direct current stimulation is a new non-invasive technique that applies weak electrical currents through the skull and has been shown to alter the excitability of certain brain areas. It is currently being tried in disorders where there is abnormal brain excitability, such as epilepsy and depression. A few studies have also been able to diminish drug craving, suggesting that brain excitability might also be altered in drug addiction. This study aims at non-invasively changing the excitability of certain brain areas-a procedure called neuromodulation- in order to help smokers quit smoking more easily.
Cardiovascular disease is a major public health problem in our country. Among the causes of cardiovascular diseases are High Blood Pressure (HBP) and Diabetes Mellitus (DM). Type 2 diabetes (DM2) is associated with a twofold risk of cardiovascular disease, and endothelial dysfunction is an early marker of vascular complications. There is evidence of action of glucagon-like peptide 1 (GLP-1) on endothelial cells and vascular smooth muscle. Vildagliptin is a drug used in the treatment of DM2 able to prolong the activity of GLP-1, improving glycemic control and endothelial function. Objectives: To evaluate the effect of vildagliptin on endothelial function in patients with DM2 and hypertension using the Endo-PAT 2000 device.
The purpose of this study was to determine if eculizumab is safe and could be used to prevent delayed graft function (DGF) following kidney transplantation.
Introduction: The life expectancy and the number of people hitting the old age have increased in recent years. The aging process is accompanied by morphological and functional changes that contribute to reduced functional capacity, increase the number of falls and the appearance of physical limitations. Exercise promotes maintenance of functional autonomy, improving the physical ability of the elderly making it more independent. Objective: To evaluate the effect of a program of muscle strengthening exercises associated with global stretching on balance, fear of falling and functional capacity in elderly women. Methods: This was a non-randomized controlled trial, in which 12 volunteers aged over 60 years were divided into two groups: intervention group (IG, n = 7) submitted to muscle strengthening exercises and stretching, 2 times per week for 12 weeks, and the control group (CG, n = 5), not submitted to the protocol but were educated about physical exercises. Before and after the protocol were evaluated scores of Berg Balance Scale, the Falls Efficacy Scale International (FES-I) and Evaluation of Functional Autonomy Development Group for Latin American Maturity (GDLAM). Data were statistically analyzed within and between groups with a significance level of p <0.05.
