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.
Patients afflicted with Chronic Heart Failure (HF) typically do not maintain stable cardiac function for the remainder of their life and consequently require continuous medical management and intermittent hospital admissions. Several investigations have demonstrated that electrical muscle stimulation (EMS) produces positive physiologic and psychological adaptations in patients with HF. However not all the EMS modalities were been evaluated on this population or not even were tested based on present recognized gold standard clinical parameters after a short period of treatment. The primary aims of the proposed study is to: Determine the effect of a five week home based of three EMS modalities on prognostics markers, perceived quality of life, muscle force and electrical activity in subjects diagnosed with HF.
The purpose of this study is to evaluate if the addition of valproic acid to standard platinum-based chemoradiation as definitive treatment of locally advanced Head and Neck squamous cell carcinoma can improve treatment outcomes, such as response rate.
The purpose of this study is to evaluate the effectiveness of a rehabilitation (physiotherapy) program in patients with acute ischemic stroke in Acute Vascular Unit and in general ward of Hospital de Clínicas de Porto Alegre, and to verify the degree of disability at fourteenth and third month, functional improvement at third month, the frequency of deaths and incidence of complications due to immobility and quantify the time spent in hospital.
The principal aim of this study is to evaluate the presence of changes in cervical vestibular evoked myogenic potentials (VEMPc) after acute intake of caffeine in healthy subjects. Secondarily, it wants to standardize normal values exam VEMPc in otorhinolaryngology service of the hospital.
Vaccinating schoolchildren against influenza would prevent the disease among non-vaccinated household members.
The aim of this study is to evaluate the effect of an early postoperative physical rehabilitation program on the functional capacity and incidence of postoperative complications in patients undergoing major elective surgery for treatment of a neoplasm
Exercise intolerance is a major complain of patients with chronic obstructive pulmonary disease (COPD). Dynamic hyperinflation has been recognized as an important limiting factor responsible for the appearance of intolerable dyspnea during exercise. Regular treatment with long-acting bronchodilators promotes a more sustained reduction of hyperinflation and consequent symptom relief and increase in the patient's ability to overcome physical demands of daily life. Tiotropium bromide (TIO) is a new generation, long-acting anticholinergic bronchodilator that significantly improves lung function, reduces symptoms and improves exercise tolerance in patients with advanced COPD. Indacaterol is a new ultra-long duration (>24 h) β2-agonist, which promotes sustained dilation of the bronchi with a once-daily administration. Compared to tiotropium, indacaterol provides evidence that is as effective as tiotropium for bronchodilation, as well as other clinical outcomes such as dyspnea and state of health. However, comparative effects of indacaterol versus tiotropium with regard to outcomes in tolerance, dyspnea and dynamic lung hyperinflation during exercise is scarce. We hypothesized that indacaterol and TIO are not different in terms of exercise tolerance and its determinants (dynamic hyperinflation and dyspnea).
The objective of this clinical study, randomized, crossover is to evaluate the pharmacokinetic profile of the polypill (atorvastatin + lorsatana + hydrochlorothiazide) Laboratory Hypermarcas S / A, in relation to drugs Citalor ® (atovastatina - Pfizer) and Hyzaar ® (losartan + hydrochlorothiazide - Merck Sharp & Dohme) by comparing the serum concentration of analytes unchanged (AT, LS and HCTZ) in healthy subjects.
Forty children considered at risk for ADHD (subclinical ADHD) will be randomized to either a neurofeedback intervention or waiting list.
The hypothesis of the proposed project is that after a fat overload, the postprandial response is different in both groups, suggesting that the LPP will present the most significant damage in endothelial vasomotion in obese individuals, especially those with GI and T2DM. After the fat overload, we hypothesized that there will be a worsening of endothelial function and microvascular reactivity in OB/DM2 and OB group compared to C, but also find lower concentrations of incretins in OB/DM2 group compared to other groups. These hypotheses may be confirmed by techniques for evaluating microvascular function, the use of DFT skin for vasomotion evaluation and finally analysis of analytes through metabolic and cardiovascular read by Multiplex kit.
