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 whether the switch from branded to generic warfarin or between different generic warfarin tablets may cause fluctuation in the results of coagulation tests (International Normalized Rate, acronym INR) in patients, thus predisposing them to unnecessary risks.
Efficacy of monthly intravitreal anti-vascular endothelial growth factor (VEGF) associated to systemic immunosuppression in patients with Vogt-Koyanagi-Harada Disease and choroidal neovascularization. Minimum follow-up 12 months. Endpoints: 6 and 12 months of follow-up. Outcome measures: improvement of VA, decrease in central foveal thickness as measured by Optical Coherence Tomography (OCT) and absence of intra/subretinal fluid.
Obsessive-compulsive disorder is a chronic condition. Even with proper treatment, no significant improvement is reached in about 30% to 40% of patients. Thus, the development of new treatment strategies is necessary. The attentional bias - ability to aversive stimuli in capturing the attention of an individual compared to a neutral stimulus - has been extensively studied. Already training attentional bias modification has been shown effective in reducing anxiety present in other anxiety disorders.This project aims to: 1 - generate knowledge on attentional bias in individuals with OCD through the use of a standardized protocol developed for OCD; 2 - available to the scientific community the first specific paradigm for the study of attentional bias in OCD patients, 3 - test the effectiveness of a training protocol for reversing attentional bias in individuals with OCD.
Intended to treat disorders of the respiratory muscles can use the device Threshold IMT ® through an inspiratory muscle training (IMT) that allows training of the inspiratory muscles, the chief of these being the diaphragm which is which objectified the improvement of its function . To monitor the action of the respiratory muscles can be used several tools such as manometer that aims to assess respiratory pressures, ie, the strength of respiratory muscles, or the Surface Electromyography (sEMG) that allow evaluating the electromyographic activity of muscles analyzed. From a quantitative clinical trial, randomized and blinded, composed of 45 individuals obtained by random convenience and divided into three groups, COPD participating in a pulmonary rehabilitation program (RP) which will make TMI (TGR - Trained Group Rehabilitated), COPD does not participant in a PR program (TGNR - Trained Group not Rehabilitated) and a control group composed of healthy individuals (CG) that seek to analyze the electromyographic activity of sternocleidomastoid (SCM) and diaphragm muscle strength, lung volumes and breathing patterns before and after a period of eight weeks of TMI. Manual will also be held dynamometry to compare the grip strength of the CG, TGR and TGNR only at baseline. Hypothesis: 1. The Inspiratory Muscle Training (IMT) increases the maximal inspiratory pressure (MIP) in COPD patients regardless of whether they are enrolled in a program of pulmonary rehabilitation (PR). 2. TMI alters the breathing pattern in COPD patients regardless of whether they were entered into a PR program. 3. Patients with COPD who do not participate in a PR program have higher handgrip strength compared to patients who did not participate in a PR program. 4. There is decreased activity of the sternocleidomastoid muscle due to increased activity in the diaphragmatic muscle fibers after a period of TMI. 5. TMI in COPD patients participating in a program RP produces greater increase in MIP, the handgrip strength, improves breathing pattern and a greater reduction in the activity of the SCM muscle and diaphragm than in those who did not participate in a program RP. 6. There will be a reduction in respiratory rate, heart rate, systolic and diastolic blood pressure and increased oxygen saturation at the end of the TMI. 7. TMI reduce the degree of dyspnea reported by patients as MRC scale at the end of the training period.
PST (pulsed signal therapy) is a unique form of pulsed electromagnetic field therapy (PEMF) for stimulating healing of damaged structures such as cartilage, bones and soft tissues. The physical effect of the pulsed electromagnetic field (PEMF) has been focus of research in various studies, with cartilage being the most studied, and which has demonstrated an increase in the synthesis of proteoglican and collagen in vitro. This is an randomized, controlled and double blind clinical trial. The main objective is to evaluate clinical improvement regarding anterior knee pain after PST intervention in patients with patellar condropathy.
This multi-center, open-label, single-arm, Phase IIIb study will evaluate the safety and efficacy of subcutaneous RoActemra/Actemra alone or in combination with non-biologic disease modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis patients in Latin America with an inadequate response to non-biologic DMARDs.
The purpose of this study is to determine whether 500 mg Glucosamine Sulfate / 400 mg Chondroitin Sulfate Capsules and 1500 mg Glucosamine Sulfate / 1200 mg Chondroitin Sulfate Sachet is effective and safe compared Cosamin DS ® Capsule in Treatment of Knee Osteoarthritis.
The purpose of this study is to observe the behavior of kinematic variables in children with spastic hemiparetic cerebral palsy (SHCP), immediately after treadmill gait training with ankle loading. The children underwent a single treadmill training session with ankle loading. The kinematic parameters were assessed in three phases: before training (PRE); immediately after training (POST); and 5 minutes after the end of training (FOLLOW UP). The investigators hypothesized that the treadmill gait training with additional lower limb loading would be a disturbance capable of modifying the locomotor strategy of children with SHCP, by the increase in kinematic parameters in the swing phase of gait.
Lymphangioleiomyomatosis (LAM) is a rare disease in which reduced exercise capacity is frequently present. The mechanisms applied are airflow obstruction, abnormal diffusion capacity and dynamic hyperinflation (DH). Pulmonary rehabilitation (PR) has proved benefit in improving exercise tolerance, dyspnea, and quality of life in chronic obstructive pulmonary disease. There are no studies evaluating the impact of PR in patients with LAM. The hypothesis under study is that PR determine improvement in exercise capacity, dyspnea, quality of life, muscle force, functional limitation and DH in these patients.
The purpose of this study is to determine if favipiravir is effective in reducing the time to resolution of influenza symptoms.
