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 objective of this study was to evaluate the effect of the orthodontic retainer on transverse maxillary dental and skeletal stability after SARME.
This study will provide efficacy and safety data of the secukinumab pre-filled syringe (PFS) for subcutaneous self-administration in patients with active rheumatoid arthritis who are intolerant to or have had an inadequate response to anti-TNF-α agents.
Advances in intensive care and mechanical ventilation (MV) in the past two decades have increased critically ill patient survival. However, some patients require prolonged MV (PMV) and are deconditioned due to respiratory insufficiency caused by underlying disease, adverse effects of medications, and prolonged immobilization. Patients in the intensive care unit (ICU) are often confined to their beds, which results in inactivity, immobility, and severe osteomyoarticular system dysfunction. Our hypothesis is that an early mobilization protocol improves muscle thickness (MT) of the quadriceps femoris, peripheral muscle strength, perceived functional status, gait speed, quality of life, duration of mechanical ventilation, ICU length of stay of the critically ill patient. The purpose of this study is to evaluate the effects of implementation an early mobilization protocol in critically ill patients in the Intensive Care Unit of the University Hospital of Santa Maria.
Chronic treatment of stable angina with nitrates long and short action is extremely frequent. In clinical practice the most commonly observed is a combination of anti-anginal agents, usually including nitrates fixed in an attempt to improve the quality of life of patients, which is not always met with success. Numerous questions and problems are seen with chronic use of oral nitrates. From a practical standpoint, some advocate the withdrawal of medication in stable patients, while many physicians still hesitate to withdraw the medication by the lack of definitive information about its consequences. In this sense there is a rationale for the attempted removal of nitrate fixed these patients, although evidence to support this action have not been adequately evaluated.
Cells damaged by hyperglycemia are unable to downregulate glucose entrance in presence of high extracellular glucose resulting in intracellular activation of deleterious biochemical pathways. Expression of GLUT-1, the major glucose transporter in mesangial cells, is increased and participates in the induction of diabetic nephropathy. Variants in the gene encoding GLUT-1 (SLC2A1) have been associated to this diabetic complication. The aim of this study was to test whether polymorphisms in SLC2A1 confer susceptibility to diabetic nephropathy in Brazilian type 1 diabetes patients.
Primary Objective: To assess, in the same study, the safety of sarilumab and tocilizumab in participants with rheumatoid arthritis (RA) who were inadequate responders to or intolerant of tumor necrosis factor (TNF) antagonists.
Objective: HIV infected individuals present a cluster of conditions that activate or injure the vascular endothelium. The administration of folates may exert beneficial effects on endothelial function in different populations at risk for cardiovascular disease. The aim of the study was to determine the effects of 4 weeks folinic acid supplementation on forearm vascular responses during reactive hyperemia in HIV-infected people under antiretroviral therapy. Methods: This was a prospective, randomized, double-blind, placebo-controlled trial to compare the effects of 4 weeks daily ingestion of 5 mg folinic acid (n=15) or placebo (n=15). Participants had to be on anti-retroviral therapy for at least 6 months before enrollment, with undetectable viral load, and CD4 cell count > 200 cells/mm3. Vascular function was evaluated with venous occlusion plethysmography at baseline and after 4 weeks, for the determination of brachial artery reactive hyperemia, and after isosorbide dinitrate administration
This open-label, multi-center, three-period, one sequence study will investigate the effect of rifampin on the pharmacokinetics of vemurafenib in patients with unresectable BRAFV600-mutation positive metastatic melanoma or other malignant tumor type that harbors a V600-activating mutation of BRAF without acceptable standard treatment options. Patients will receive a single dose of vemurafenib in Periods A and C and multiple doses of rifampin in Periods B and C. Eligible patients will have the option to continue treatment with vemurafenib as part of an extension study (NCT01739764). The anticipated time on study treatment is approximately 24 days.
Many author have exposed the rapid and slow expansion, the diversity of activation and containment protocols and the follow-up time, justify the need for more studies to evaluate the effects to the ERM for the long-term.
Primary Objective: To demonstrate the treatment effect of sarilumab and methotrexate (MTX) compared to etanercept and methotrexate (MTX) in patients with rheumatoid arthritis (RA) and an inadequate response to adalimumab and methotrexate by evaluation of the Disease Activity Score for 28 joints (DAS28). Secondary Objectives: To assess the signs and symptoms of rheumatoid arthritis (RA) in patients taking sarilumab in combination with methotrexate (MTX). To assess the quality of life of patients with rheumatoid arthritis (RA) taking sarilumab in combination with methotrexate (MTX). To assess the safety and tolerability of sarilumab in combination with methotrexate (MTX) in patients with rheumatoid arthritis (RA).
