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.
Background: Patients with chronic kidney disease on hemodialysis may have reduced diffusion capacity, lung function and gas exchange due to mechanical and hemodynamic changes in the respiratory system, and decreased respiratory muscle strength resulting from uremic myopathy. The inspiratory muscle training (IMT) appears as an instrument to improve the inspiratory muscle strength, with positive effects on functional capacity and quality of life of kidney patients, however, the effects of IMT were not addressed in the specific variables of the respiratory system and to date there are no studies on the use of daily training in this population. Objective: To evaluate the effectiveness of daily inspiratory muscle training on respiratory muscle strength, chest wall volume, diaphragm thickness and mobility of end-stage renal disease patients. Methods: A randomized controlled clinical trial to be developed in Cardiopulmonary Physical Therapy Laboratory of the Universidade Federal de Pernambuco (UFPE) during the period from November 2015 to December 2016. The sample is composed of 24 individuals aged 18 and 65, having CKD, to perform hemodialysis for at least twelve months and provide inspiratory muscle weakness. Patients will be divided into two groups, the training group will be IMT with POWER-breathe®, load of 50% of MIP, duration of three sets of 30 inspirations, frequency of two sessions per day, 7 days a week for 8 weeks, since the sham group will be subjected to the same procedure (duration and frequency), but without load. Participants will be assessed before and after intervention through a global assessment form, questionnaire Kidney Disease Quality of Life Instrument Short Form - KDQOL-SF, diaphragmatic ultrasound, opto-electronic plethysmography, spirometry, manometer and six-minute walk test.
The primary objective of this study is to evaluate the effects of gabapentin in sleep polysomnography parameters and in nocturnal secretion of endogenous hypothalamic-pituitary-adrenal (HPA), hypothalamic-pituitary-gonadal (HPG) and somatotropic axes hormones and basal IGF-1 in older men.
Assessment of energy expenditure and the quadriceps muscle fatigue of healthy seniors, after two physical activities, being one of an activity guided by interactive video game (Xbox) and another on the treadmill. The participants will perform the activities in two different days, the order will be obtained by randomization.
The aim of this study was to assess the effectiveness of resistance training in improving functional capacity, muscle strength, quality of life and disease activity in patients with PSA.
Myelofibrosis patients with high molecular risk mutations have an intrinsically aggressive disease with increased risk of leukemic transformation and reduced overall survival. As there are no therapies currently established in the subset of high molecular risk patients with early myelofibrosis, the study aimed to evaluate ruxolitinib in this patient population.
Obesity is considered one of the most troubling chronic diseases for public health because of its rapid growth in the population. Many are the causal factors of this epidemic, and in recent years studies suggest the involvement of genetic factors in the etiology of obesity as a risk factor for its development. Polymorphism of the FTO gene is being studied in the past eight years and has been indicated as a predictor of obesity in the population, as well as associations in food intake, raising the possibility of influence in the regulation of hunger and satiety. Accordingly, researchers observed changes in levels of postprandial leptin and ghrelin, which can promote appetite and change the quantity and quality of food intake in subjects with the polymorphism FTO.
Systemic Sclerosis (SSc) is a devastating disease of unknown etiology. Patients suffer from multiple organ fibrosis whereas lung fibrosis (interstitial lung disease, ILD) is one of the main driver for mortality. There is preclinical evidence for efficacy of nintedanib in SSc and associated ILD (SSc-ILD) and the anti-fibrotic efficacy of nintedanib was proven in idiopathic pulmonary fibrosis patients, who are presenting a similar pattern regarding lung fibrosis. Hence it is the purpose of the trial to confirm the efficacy and safety of nintedanib 150 mg bid in treating patients with SSc-ILD, compared with placebo. The trial will be conducted as a double blind, randomised, placebo-controlled trial with primary efficacy evaluation at week 52 and placebo-controlled treatment until last patient out (up to a maximum of 100 weeks). Respiratory function is globally accepted for assessment of treatment effects in patients with lung fibrosis. The chosen endpoint (Forced Vital Capacity (FVC) decline) is easy to obtain and is part of the usual examinations done in patients with SSc-ILD.
The purpose of this study is to describe the genetic diversity of Hepatitis C virus (HCV) NS3/4a protease and NS5A protein of HCV in participants with chronic disease naive-drug or previously failed to double therapy (Peg-interferon and Ribavirin) and to identify the frequency of natural polymorphisms in HCV NS3/4a protease and NS5A protein that are associated with direct-acting antivirals (DAAs)-resistance.
RE-COVERY is a large, multi-national, multi-center observational study based on new data collection. The study will enroll and characterize patients within 30 days of being diagnosed with an acute DVT and/or PE. The study has two main objectives. Objective 1 will characterize the DVT / PE patient population. All patients with a DVT and/or PE will be enrolled for cross-sectional characterization of the VTE patient population. Objective 2 will compare the safety and effectiveness of dabigatran etexilate regimens for treatment of VTE in comparison to VKA regimens. Patients treated with dabigatran etexilate or VKA will be followed up for the occurrence of outcome events for up to one year.
The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.
