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 with advanced coronary artery disease usually undergo incomplete myocardial revascularization due to the extension and diffuseness of the disease, with very poor distal arterial beds unsuitable for direct revascularization. This study was designed to test the hypothesis that direct, intramyocardial injection of autologous bone marrow cells may further improve myocardial perfusion in patients undergoing incomplete bypass surgery.
This study compared the correct use of and patient preference for two drug delivery systems (inhalers) in patients with COPD
Evaluate if the elastic tapping application on the scapular region can interferer immediately on the performance during the upper limb closed kinetic chain test on jiu jitsu practitioners.
The purpose of this study is to evaluate efficacy, safety and tolerance of long-acting risperidone when switching from oral antipsychotics in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).
The goal of the project is to investigate the clinical efficacy of management of early caries lesions by resin infiltration and to further scrutinize the patient stress experiences.
Silicosis is a chronic and incurable occupational disease that can progress independent of the end of exposure. Recent works suggest that the Forced Oscillation Technique (FOT) may help to improve our understanding of the changes in lung mechanics, as well as in the detection of these changes. Objectives: Analyze the effects of airway obstruction in silicosis on the respiratory impedance and evaluated the diagnostic use of the FOT in these patients. For this, the investigators used spirometry to classify airway obstruction, which resulted in four categories: control, patients with normal exam, mild obstruction, and moderate-to-severe obstruction. Resistive data were interpreted using the zero-intercept resistance (R0), the resistance at 4 Hz (Rrs4) and the mean resistance (Rm). The investigators also analyzed the mean reactance (Xm) and the dynamic compliance (Crs,dyn). The total mechanical load was evaluated using the absolute value of the respiratory impedance (Z4Hz). The diagnostic potential was evaluated by investigating the area under the receiver operating characteristic curve (AUC).
This study's general objective was to evaluate the efficacy of nursing orientation to reduce the anxiety of patients with acute coronary syndrome undergoing bed bath. The specific objectives included: the development and validation of an informative manual concerning bed bath; correlation of physiological variables (systolic and diastolic blood pressure and heart and respiratory rate) with the patients' state anxiety; correlation of antecedent variables (age, gender, cardiovascular risk factor, use of beta blockers, trait anxiety, depression, prior hospitalization, prior experience with bed baths, the patients' preference for a female or male professional to perform the bath, pain, fear, and embarrassment) with the patients' state anxiety.
The purpose of this study is to evaluate if carvedilol can prevent the cardiotoxicity after chemotherapy in breast cancer.
Daily lung ultrasound can help weaning from mechanical ventilation in difficult-to-wean adult patients. In this randomized trial, standardized lung ultrasound will be performed daily asssociated with standardized interventions aiming to decrease the total time in mechanical ventilation.
This multi-center, open-label, randomized study will evaluate the participant preference with subcutaneous versus intravenous administration of MabThera/Rituxan (rituximab) in participants with CD20+ diffuse large B-cell lymphoma or CD20+ follicular non-Hodgkin's lymphoma. In Arm A, participants will receive MabThera/Rituxan 375 mg/m2 intravenously (IV) on Day 1 of Cycle 1 and MabThera/Rituxan 1400 mg subcutaneously (SC) on Day 1 of Cycles 2-4, followed by MabThera/Rituxan IV in Cycles 5-8. Participants in Arm B will receive MabThera/Rituxan IV in Cycles 1-4 and SC in Cycles 5-8. All participants will receive 6-8 cycles of standard chemotherapy (according to local country practice) with 8 cycles of MabThera/Rituxan. Anticipated time on study treatment is up to 24 weeks.
