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.
This prospective nonrandomized study comprised patients with cataract, corneal astigmatism, and motivation for spectacle independence. In all cases, a Rayner M-flex® T toric Intraocular Lens will be implanted in the capsular bag. Three months postoperatively, distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity will be evaluated. A patient-satisfaction and visual phenomena questionnaire will also be administered.
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are widely used as part of combination antiretroviral therapy (ART) for infants and children, but NNRTI resistance is increasing, leading to treatment failure. This study tested the safety, tolerability, and dosing levels of etravirine (ETR), a new NNRTI.
Objective: The aim of this study is to assess the effectiveness of an oral health educative intervention in preventing early childhood caries (ECC). Methods: The trial targets 0- to 12-month-old children and their mothers in Pelotas, Brazil. Twenty-four public health centres (clusters) were randomly selected and assigned to intervention or control group (12 clusters per intervention group). In each center, up to 30 children/mothers were selected and invited to participate in the trial. Each mother was interviewed in order to collect socio-economic and demographic variables. The intervention group received by means of a pamphlet the oral health instructions, which were emphasized with verbal instructions. Dental examination will be carried out after 1 year for all teeth surfaces to determine caries status.
Blood transfusion during perioperative period in patients undergoing to major surgery has been associated to several postoperative complications. Particularly in oncologic surgery, red blood cell transfusion has been investigated as a factor of worse outcome and cancer recurrence due to postoperative impairment of cellular immunity. Although red blood cell transfusion has decreased in worldwide clinical practice, this issue still remains a matter of controversy in oncologic surgery. There are no prospective studies comparing outcomes between restrictive or liberal of blood transfusion strategy in oncologic surgery. This study is a prospective and randomized study comparing clinical outcomes between two strategies of transfusion in oncologic surgery - liberal or restrictive
This is a randomized controlled trial, with blinded assessor to evaluate the effectiveness of Pilates to treat low back pain. Hypothesis - the Pilates group will have best results than the control group (usual medicament treatment).
The aim of the study is to evaluate the effectiveness of cross-toothbrushing technique compared with anteroposterior and biofilm removal and control of caries lesions in first permanent molars.
The propose of this study is to determine whether N-acetylcysteine is effective in reversing the changes in thyroid hormones seen in critical illness, known as the low T3 syndrome.
Primary Objective: To demonstrate progression free survival (PFS) improvement for cabazitaxel compared to topotecan in participants with sensitive or resistant/refractory small cell lung cancer following a first line platinum based chemotherapy. Secondary Objectives: - To assess disease progression free rate at 12 weeks - To assess Response Rate (Response Evaluation Criteria in Solid Tumor [RECIST] 1.1) and duration of response - To assess Overall Survival (OS) - To assess the Safety (National Cancer Institute - Common Toxicity Criteria [NCI-CTC] version 4.03) - To assess the Health-Related Quality of Life (HRQoL)
The purpose of this study is to evaluate the feasibility, safety and effects in inflammatory response of the therapy with a probiotic agent, the yeast Saccharomyces boulardii (SB), in chronic heart failure patients.
The purpose of this study is to evaluate the effects of Ceftazidime Avibactam plus Metronidazole compared to Meropenem for treating hospitalized patients with complicated intra-abdominal infections.
