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.
Carbohydrate enriched-drinks has been used as preoperative treatment up to two hours before anesthesia. These drinks are safe and are not associated to bronchial aspiration during anesthesia. The addition of protein may be beneficial for metabolic preconditioning but there is a few data in literature testing these drinks for safety. The aim of the study will be to investigate the residual gastric volume (RGV) measured during the gastroscopy with abbreviation of fast to 2h with a carbohydrate plus whey protein enriched-drink.
The aim of this study is to determine the recovery time of moderate neuromuscular blockade with sugammadex in adults pretreated with magnesium sulfate.
The primary purpose of the study was to compare the antitumor activity of LDK378 versus reference chemotherapy. Patients in the chemotherapy arm were given the option to switch to LDK378 after confirmed progressive disease (PD), while also had the choice to continue with pemetrexed treatment.
The purpose of this study was to determine the washout pharmacokinetics (PK) and safety of in utero/intrapartum exposure to maternal raltegravir (RAL) in infants born to pregnant women with HIV infection who received RAL 400 mg twice daily. The study also provided data for the development of an infant RAL starting dosing regimen for IMPAACT P1110 (NCT01780831).
Efficacy and Safety Trial of elobixibat in Patients with Chronic Idiopathic Constipation treated for 26 Weeks.
The prevalence of obesity and type 2 diabetes mellitus (T2DM) has increased progressively in the past decades, and consequently, a higher incidence of cardiovascular diseases is observed. As this process develops, the endothelial dysfunction is present at early stages of the atherosclerotic disease. Studies conducted at BioVasc/UERJ show the occurrence of endothelial and microvascular dysfunction in obese carriers, even in the absence of dysglycemia. New concepts indicate the endothelium as a possible therapeutic target, and drugs which act not only on diabetes mellitus pathophysiology but also acting as direct cardiovascular protectors bring new therapeutic possibilities. The dipeptidyl-peptidase-4 inhibitors (DPP4), such as vildagliptin, are drugs used on the T2DM treatment. Its incretin mimetic and insulinotropic effects are already well established and several other studies show its effectiveness in reducing glycated hemoglobin, even in monotherapy. Currently, fat rich foods are being increasingly introduced in the western way of life and recent evidence suggests that the postprandial lipemia (LPP) is related to cardiovascular risk. A better glucose control using vildagliptin can reduce the oxidative stress, and consequently promote a better microvascular and endothelial reactivity. However, vildagliptin can have an additional cardiovascular protective action, not only because of its effect on glycemia and oxidative stress reduction, but maybe because of its direct effect on intestinal peptides with postprandial lipemia reduction. To test this hypothesis, we will proceed the following exams: venous occlusion pletysmography, nailfold videocapilaroscopy and laser-Doppler flowmetry aiming to evaluate vascular reactivity on muscle and at cutaneous site. Anoter group of patients with the same clinical charactherisitics will use metformin, in order to compare its effects with those obtained from the use of Vildaglitpin. Our purpose is to determine whether vildagliptin, evaluated in obese and diabetic women, has vascular protective effects, and whether the regulatory mechanisms of these actions correlate with oxidative stress, inflammatory markers and intestinal peptides in baseline state and after a lipid overload.
The study hypothesis is chest wall muscle stretching increase distribution of volume variation of thoracoabdominal wall and reduce electromyographic activity of respiratory muscles in patients with Chronic Obstructive Pulmonary Disease.
Dystrophinopathy is a disease continuum that includes Duchenne muscular dystrophy, which develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of dystrophinopathy in approximately 10-15 percent (%) of boys with the disease. Ataluren is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. The main goal of this Phase 3 study is to evaluate the effect of ataluren on walking ability. The effect of ataluren on physical function, quality of life, and activities of daily living will be evaluated. This study will also provide additional information on the long-term safety of ataluren.
Background and aims:Constipation is a frequent complaint and the combination of a prebiotic and probiotics would have a potentially synergic effect on the intestinal transit. The present study therefore aims to investigate the combination of polydextrose (Litesse®), L. acidophilus NCFM® and B. lactis HN019 in a yogurt on intestinal transit in subjects who suffer from constipation. Methods: Patients with constipation were randomly divided into two groups, Placebo Group (PG) and Treatment Group (TG), and had to eat 180 ml of unflavored yogurt every morning for 14 days. Those in the CG received only yogurt, while the TG received yogurt containing polydextrose, L. acidophilus NCFM® (ATCC 700396) and B. lactis HN019 (AGAL NM97/09513). Expect that patients who took a combination of polydextrose has a decrease in the colonic transit time (CTT) when comparing initial and final transit time.
Viscosupplementation by intra-articular injection of hyaluronate products has recently gained popularity as a treatment modality of gonarthritis.There is not, however, a consensus on the best method.Our objective is to evaluate what is the best dosage of viscosupplementation with hyaluronic acid (OSTEONIL®) associated with 1 ml (20 mg) of triamcinolone hexacetonide. One hundred and four patients with knee osteoarthritis (KOA) were divides into 2 groups of 52 patients each to receive either a single application of 3 ampoules of OSTEONIL® + 1ml of Hexacetonide of triamcinolone or three applications of 1 ampoule of OSTEONIL®, one per week for three weeks + 1ml of Hexacetonide of triamcinolone only in the first injection. Primary endpoint was clinical results expressed by Visual Analogic Scale of pain (VAS), Western Ontario and Mcmaster Universities (WOMAC) and Lequesne questionaires at one, three, six and 12 months after the procedure
