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.

Phase 4 study to evaluate the immunogenicity and Safety of the 17DD Yellow Fever vaccine in HIV infected individuals, compared to non-HIV-infected individuals. Main objective: To compare the proportion of seroconversion and the geometric mean of neutralizing antibodies 30 days and 365 days after vaccine. Secondary objectives: To evaluate whether the titles of neutralizing antibodies are associated with CD4 lymphocyte counts, CD8 lymphocyte counts, CD4 nadir, HIV viral load and use of antiretroviral therapy. To assess the yellow fever vaccine viremia at day 10 after vaccine.To compare the incidence of adverse events in HIV-infected and non-HIV-infected individuals.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic and progressive airflow limitations and subjects with COPD also experience exacerbations characterized by the worsening of respiratory symptoms. It's necessary medical intervention, changes in regular medication, and the use of antibiotics and/or corticosteroids followed or not by hospitalization. The exacerbations contribute to worsening of the disease with systemic impairment and muscle weakness is a very relevant event. The physical inactivity, especially related to bed rest, comprises one of the factors contributing to muscle atrophy and loss of muscle strength. Thus, the intervention performed during hospitalization is necessary to minimize the consequences which causes impairment in health status subjects. The aim of the study is assess the effect of the intervention with elastic bands, in muscle strength,level of the physical activity, functional capacity, dyspnea on activities of daily living (ADL) and quality of life in COPD exacerbation subjects. Moreover,verify the intervention benefits over 01 and 03 months post exacerbation episode. It will be a prospective, randomized, longitudinal and interventional study. The investigators will be asses both gender patients with exacerbation of COPD in 4 situations: First time (at least 24 and at most 48 hours after the beginning of medical therapy); seven days post the first assessment; one and three months post exacerbation episode. It will be assess the muscle strength, physical activity level, functional capacity, dyspnea on ADL and quality of life. The patients will be randomized in 2 groups: intervention and control group. The intervention will be performed with elastic bands once a day during seven days. The investigators expected that patients of the intervention group will present better muscle strength, physical activity level and functional capacity than the control group. Furthermore, an improvement in dyspnea and quality of life is expected in intervention group when compared as with control group patients. It is hypothesized that the benefits of intervention will be maintained over one month.
The objective of this Bayesian Adaptive trial is to compare a control group versus a comprehensive ulcer healing protocol. The latter involves a combination of compressive therapy, miokinetic drainage and muscle strengthening for the entire lower extremity pump among patients with lower extremity venous ulcers. The investigators hypothesized that the combined therapy will have a higher closure rate as well as lower time to closure.
Background: Despite recent recommendations for the inclusion of upper-limb endurance training in exercise training programs (ET) for patients with COPD, the majority of theses programs are yet focused only in lower-limb endurance training. However, these patients may have a hindered performance during the execution of simple activities of daily living (ADL) involving the upper-limbs. Therefore, one doubt remains: is the addition of upper-limb endurance training necessary? Aims: To verify whether patients with COPD become more physically active in daily life, as well as whether they improve ADL performance after two protocols of ET: 1) traditional ET (TET; endurance exercises of the lower-limbs and strengthening exercise for upper- and lower-limbs) and 2) TET + additional upper-limb endurance exercise (AULET). Methods: Patients with COPD (n= 64) will be included in this randomized controlled clinical trial. Before randomization to TET or AULET patients will be evaluated regarding physical activity in daily life (PADL; accelerometers), lung function (plethysmography), respiratory muscle strength (maximum ins- and expiratory pressures), body composition (bioelectrical impedance), performance in ADL (Londrina ADL protocol), maximum exercise capacity (symptom limited maximum test of lower and upper limbs), submaximal exercise capacity (endurance time at 80% of the maximum upper- and lower-limb capacity), functional exercise capacity (six-minute walk test and six-minute pegboard and ring test), peripheral muscle strength (one-repetition maximum test and dynamometry), healthy-related quality of life (Chronic Respiratory Questionnaire), health status (COPD assessment test), functional status (London Chest Activity of Daily Life scale) and symptoms of anxiety and depression (Hospital Anxiety and Depression Scale). Patients in both groups will exercise three times per week for 12 weeks. TET will be composed by endurance exercise for the lower-limbs (walking on treadmill and lower-limb cycling) plus strengthening exercises for upper- and lower limbs. Group AULET will perform the same exercises plus the additional upper-limb endurance training (upper-limb "cycling"). Patients will be evaluated by the same procedures after the ET. Hypothesis: The addition of upper-limb endurance training will increase PADL and ADL performance to a greater extent than the traditional exercise-training program alone due to greater reduction of physical activity-related dyspnea.
RADICAL PC1 is a prospective cohort study of men with a new diagnosis of prostate cancer. RADICAL PC2 is a randomized, controlled trial of a systematic approach to modifying cardiovascular and lifestyle risk factors in men with a new diagnosis of prostate cancer.
Evaluate the effectiveness of a Whole body vibration training program on quadriceps muscle strength, functional capacity and respiratory muscle strength in adult renal transplant recipients
Hypoestrogenism leads to vaginal wall changes resulting in diminished vaginal lubrication and, consequently, causing pain during intercourse. Topical estrogen therapy (THT) may control this complaint. However, there are limitations on its use, especially in patients with breast cancer and diagnosed endometrial cancer. This randomized clinical trial aims to assess the impact of local estriol therapy in postmenopausal women complaining of coital pain and to assess serum concentrations of estriol in these women after estriol use. One-hundred-thirty-two women aged between 40 and 65 years will be randomized into three groups: Women using estriol 1 mg / 1g at the proximal third of vagina every other night - estriol proximal group (PEG), women in using estriol 1 mg / 1g at the distal third of the vagina every other night - estriol distal group (DEG), gel group (GG) using water-based during intercourse.
This study investigates the effects of nutritional counseling versus standard nutritional care on nutritional status and quality of life in patients with head and neck cancer submitted to radiotherapy.Half participants will receive intensive nutritional counseling while the other half will receive standard care.
Introduction: Renal transplantation represents the therapeutic mode with more durable treatment, greater cost-effectiveness, survival benefits and quality of life of the patients, however, with high cardiovascular mortality. Objectives: To evaluate the acute and chronic effects on heart rate variability and the impact of chronic kidney disease on cardiorespiratory fitness in renal transplant recipients following a full-body Vibration training program. Methods: It will be a blinded randomized clinical trial (patient, evaluator and statistician), controlled and endowed with secrecy of allocation, to be performed in the Cardiopulmonary Physiotherapy Laboratory of the Physiotherapy Department of the Federal University of Pernambuco. Renal transplant recipients will be recruited at the Nephrology outpatient clinic of the Hospital das Clínicas de Pernambuco, according to the following inclusion criteria: age between 18 and 59 years, who underwent transplantation at least one year before and present a stable transplant function through the level Of creatinine
