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.
Chronic hepatitis by the B virus (HBV) and/or by the C virus (HCV) is a major public-health problem since it presents a long phase of clinical latency which makes its early diagnosis difficult and results in the development of a large number of cases to complications such as cirrhosis, hepatic insufficiency and hepatocarcinoma. In Brazil, it is estimated that the number of HBV is two million, of which 72 thousand have been reported. As regards HCV, the ratio is one of three million estimated cases to 52 thousand reports. Learning about the serological profile of the users of a viral hepatitis reference service is fundamental for the planning of diagnostic and caregiving actions; therefore, it is the objective of this study.
The purpose of this study is to determine whether an early goal-directed decrement of preload and afterload with a target systolic blood pressure of 90-110 mmHg by aggressive vasodilatation in patients with acute HF in the non-ICU setting is safe, and leads to a better clinical and economical outcome
The investigators' study has 4 primary objectives. Among patients undergoing noncardiac surgery the investigators will determine: (1) the incidence of major perioperative vascular events; (2) the optimal clinical model to predict major perioperative vascular events; (3) the proportion of patients with perioperative myocardial infarctions that may go undetected without perioperative troponin monitoring; and (4) the relationship between postoperative troponin measurements and the 1 year risk of vascular death.
T. cruzi infection affects approximately five million people in Brazil. The diagnosis of the chronic phase of infection is performed by indirect serological methods which, nevertheless, leave inconclusive results. One of the direct methods used for T. cruzi identification, blood culture in LIT (liver infusion tryptose) medium, presents low sensitivity in that phase of the disease. A negative result does not eliminate the possibility of infection, but a positive test has high absolute diagnostic value, which enables the indication of antiparasitic treatment. Molecular diagnosis (PCR) in this phase is promising and can be used as a confirmatory test, particularly when individuals present inconclusive results in conventional serological tests, such as ELISA, HAI and IFI. This study aimed at improving blood culture sensitivity in LIT medium by performing PCR in individuals with positive and inconclusive serology for chagasic infection.
The purpose of this study is to examine the effectiveness and safety of insulin lispro protamine suspension (ILPS) as compared to insulin glargine as basal insulin therapy in adults with type 2 diabetes.
The purpose of this study was to evaluate progression free survival in those participants assigned everolimus 10 mg/day plus Best Supportive Care versus those assigned to placebo plus Best Supportive Care in Advanced Neuroendocrine Tumors of pancreatic origin.
The purpose of this study is to compare the efficacy and safety of intra-articular glucocorticoid injection to its systemic use for treatment of knee synovitis in patients with Rheumatoid Arthritis
Recent meta-analysis reported reduction in mortality and hospitalization of HF patients.However, important issues in DMP for HF remain to be resolved. DMP are not homogeneous concerning methodology and in general included only elderly patients; most were tested in high-risk HF patients discharged from hospital; quality of life results are controversial; few reports included long-term results; some protocols had limited enrollment of screened patients, and it was suggested that could be less effective when patients are already followed by HF specialist.Improved survival was associated with cardiologist care as well with multidisciplinary teams providing specialized follow-up.Whether both together could benefits HF is not well defined. Also, no studies reported the long-term effects of a cyclic repetitive reeducation program.We tested whether a DMP that consisted of a long-term repetitive education program associated with a telephone monitoring could benefit HF outpatients in usual ambulatory care already under care of cardiologist with experience in HF
This study will assess safety and efficacy of AEB071 combined with everolimus in a CNI-free (calcineurin inhibitor) regimen in renal transplant recipients.
This 3 arm study will evaluate renal safety after administration of an intravenous (iv) injection or infusion of Bonviva, compared to oral alendronate, in patients with postmenopausal osteoporosis, at increased risk of renal disease. Patients will be randomized to receive Bonviva 3mg intravenous (iv) by a) injection or b) infusion once every 3 months, or alendronate 70mg per oral (po) weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
