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 analyze the efficacy of syndecan-4 as a biomarker on the Chagas Disease prognosis. This analysis will be done through the correlation between the plasmatic levels of this molecule with functional and laboratory tests.

Multicenter prospective follow-up of a not controlled chronic hepatitis C genotypes 2/3 patients cohort with treatment indication with interferon α 2b and ribavirin for 24 weeks, and the verification of sustained virological response at week 48. The eligibility criteria and outcome measures followed the Clinical Protocol and Therapeutic Guidelines for Chronic Viral Hepatitis C, published by the Ministry of Health: http://portal.saude.gov.br/portal/arquivos/pdf/pcdt_hepatite_c_2011_retificado.pdf
The purpose of the study is to investigate the effects of Conjugated Linoleic Acid (CLA) from dairy products on fatty acid metabolism and human health. A CLA depletion-repletion study was carried out with healthy volunteers. CLA depletion was achieved through an eight-week dairy fat restriction, followed by an eight-week repletion period consisting of intake of a butter naturally enriched with CLA. Changes in body composition, fasting glucose and insulin, inflammatory mediators, cell membranes' stability, plasma lipid levels and fatty acid composition of lipid classes are evaluated after depletion and repletion phases.
The aim of this study was to evaluate the influence of a fitness program from the application of Pilates on lung function, thoracoabdominal mobility and respiratory muscle strength in women.
Fibromyalgia Syndrome (FS) is one condition that most affects functional performance, especially in women, due to alterations in the entire musculoskeletal system. Given that, Physical Therapy (PT) studies the human movement and its dysfunctions, and that FS, because of its complex chronic characteristic, impairs the affected individual's activities causing movement disorders, a PT professional must be part of the multidisciplinary team involved in the FS treatment. Nonetheless, as explained in the present proposal, several aspects still need clarification related to the PT role in this syndrome. Particularly, studies that analyze the biomechanical, sensorial and cardiorespiratory adaptations in individuals who undergo PT intervention still lack; those studies would contribute with scientific evidence to the clinical practice. According to recent systematic reviews, one of the most used therapies with positive effects on FS subjects is the hydrotherapy, which combines exercises and the water relaxing effects. Other alternative treatments have also been searched, in an attempt to decrease the painful picture presented, as the FS etiology and pathophysiology are not well known. The aim of this study is to evaluate the efficacy of different physical therapy resources in the FS, in two subprojects. The first will verify if hydrotherapy is effective in modifying movement variables (scapular kinematics and electromyography) and autonomic modulation. Other variables, such as pain level and quality of life in women with FS, will also be analyzed. The second study will evaluate the efficacy of the Shiatsu massage on pain, sleep quality, balance and quality of life of subjects with FS.
Background: The use of ultrasound in regional anesthesia enables a reduction in the local anesthetic volume. The present study aimed to determine the minimum effective concentration (EC50 and EC95) of bupivacaine for axillary brachial plexus block (ABPB). Methods: Following approval by the Research Ethics Committee, patients with a physical condition of I or II according to the American Society of Anesthesiologists, between 21 and 65 years of age were recruited and subjected to elective surgery of the hand and ABPB. The concentration of the anesthetic was determined using a step-up/step-down method and was based on the outcome of the preceding block.
The current available antiretroviral (ARV) agents make possible a successful treatment of virtually all HIV-infected patients, but some problems related to early mortality are still of concern, mainly in resources-limited settings. There are several published reports showing that such patients are at a significantly higher risk of death during the first months of treatment, in comparison with the observed outcomes in developed countries. One of the consistently detected risks for early mortality across these reports is the baseline low CD4 count, although it does not seem to be the only reason for such outcome. In Brazil and other developing countries, there is still a large proportion of AIDS patients who are diagnosed with AIDS, or only seek health care for HIV infection late in the course of disease. Dolutegravir (DTG), the first HIV-1 integrase inhibitor, is a potent and safe ARV drug. The available evidence suggest it promotes a faster decline in HIV-1 plasma viremia, and a higher increase in CD4 cells count, in comparison with those in Efavirenz (EFV) arm. The investigators propose to compare the impact of DTG versus EFV in the early mortality rates for severely ill (CD4+ cells count <50 cells/mm3) patients starting ARV therapy.
Randomized controlled clinical trials have demonstrated that the use of amoxicillin (AMX) and metronidazole (MTZ) as adjuncts to mechanical therapy improves the clinical and microbiological outcomes of scaling and root planing (SRP) in non-smokers and smokers with ChP. However, the effects of this antibiotic protocol have not been directly compared in non-smokers and smokers. Therefore, the aim of this study will be to compare the clinical and microbiological effects of the adjunctive use of MTZ+AMX to SRP in smokers and non-smokers subjects with chronic periodontitis (ChP). It was hypothesized that non-smokers would benefit better from this combination of therapies than the smokers.
Optimal management of patients with advanced NSCLC and with PS 2 remains controversial and underrepresented in clinical trials, typically accounting for 5 to 10% of enrolled patients. Patient PS 2 proportion in population-based studies is considerably higher than that included in clinical trials. Management of patients with PS of 2 in clinical practice is empirical and inconsistent. Patients have median overall survival of 3 to 5 months in randomized trials, and treatment options include best supportive care, single-agent and combination chemotherapy. Retrospective studies have suggested that patients PS 2 may benefit from first-line chemotherapy in terms of symptom improvement and overall survival. In many of these studies, single-agent chemotherapy was compared with best supportive care alone. Data on the role of cisplatin-based combinations for patients with PS 2 is more scant, with one study questioning its benefit, and another interrupting accrual because of undue toxicity. With regards to carboplatin, the Cancer and Leukemia Group B (CALGB) study 9730 compared paclitaxel plus carboplatin versus paclitaxel alone in a subgroup of 107 patients with PS 2; the median overall survival was significantly longer in group treated with combination chemotherapy (4.7 versus 2.4 months). Combination chemotherapy with carboplatin and paclitaxel also produced a statistically significantly higher incidence of severe hematological and non-hematological toxicities. On the basis of aforementioned results, a recent European panel stated that carboplatin-based or low-dose cisplatin-based doublets might represent alternative options to single-agent chemoterapy in patients PS 2. Outside clinical trials, single-agent chemotherapy with a 3rd generation agent remains valid option for patients PS2. Results demonstrate that pemetrexed is an agent with established single-agent activity in NSCLC, and suggest it is a potential candidate for combinations with platinum and other agents currently utilized for patients with advanced NSCLC. Favorable toxicity profile of pemetrexed suggests that this agent is an ideal candidate for single agent testing and in combination among patients with PS 2. Substantial doubt remains in the comparative benefit from monotherapy versus combination. Starting dose and schedule of pemetrexed were set for this study based on its current labeling in the 2nd line treatment of metastatic NSCLC and 1st line treatment of malignant pleural mesothelioma.
