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 NOVEL Observational longiTudinal studY (NOVELTY) is an observational study of obstructive lung disease and is a multi-country, multi-centre, prospective, longitudinal cohort study which will recruit patients with a diagnosis, or suspected diagnosis, of asthma and/or Chronic Obstructive Pulmonary Disease (COPD). Patients will undergo clinical assessments and receive standard medical care as determined by their treating physician. Patients enrolled in NOVELTY will be followed up yearly by their treating physician for a total duration of three years. In addition, patients will be followed up remotely every 3 months. The NOVELTY study will collect data currently lacking to allow for multinational data collection to fill regional/local gaps and improve comparability across regions.
Among the plants most used in folk medicine for the treatment of diabetes are the species of the genus Bauhinia (Fabaceae), popularly known in Brazil as "pata-de-vaca". Of these, Bauhinia forficata has the highest number of studies regarding the hypoglycemic activity. Due to this fact it is included in the Medicinal Plants List of the Brazilian Public Health System. Extracts of pata-de-vaca (B. forficata) have been explored both in relation to its chemical composition and its pharmacological potential. From the chemical point of view the main components identified in hydro alcoholic extract of the leaves are O-glycosylated derivatives of kaempferol and quercetin. Regarding pharmacological properties preclinical studies have confirmed the hypoglycemic effect and antidiabetic of the hydroalcoholic extract of the leaves of B. forficata. The search for evidence of the alleged anti-diabetic activity of B. forficata in clinical level was performed in only two studies, both with few patients, and questionable methodological quality that used tea as a pharmaceutical form, a fact that allows us to question the validity of data considering the risks of no dose reproducibility ingested by patients during the study. Thus the investigators here intend to determine the effects of a standardized extract of B. forficata in the control of patients with diabetes mellitus
This is a prospective observational cohort study of haploidentical transplantation with post-transplant cyclophosphamide for acute leukemias using reduced intensity conditioning for acute myeloid leukemia (AML) and myeloablative conditioning for acute lymphoblastic leukemia (ALL).
The Diverticular Inflammation and Complication Assessment (DICA) is an endoscopic classification for diverticulosis and diverticular disease of the colon. The aim of the study is to show that DICA classification is a valid parameter to predict the risk of acute diverticulitis occurrence/recurrence and the need of surgery in patients suffering from diverticulosis/diverticular disease of the colon.
Coronary arterial bypass graft surgery (CABG) is proven safe with improved survival and greater quality of life in patients with coronary arterial disease. Evidences on the cardiovascular and gas-exchanges responses during and right after early exercise-based rehabilitation of this patients are limited. Objective: The investigators aim to analyse breath-by-breath cardiopulmonary and metabolic responses during six-minute walk test (6MWT) and shuttle walk test (SWT) in patients with or without left ventricular dysfunction (LVD) after CABG. In addition, the investigators will investigate oxygen consumption and cardiopulmonary responses during the early exercise-based rehabilitation in the first days after surgery. Methods: According to the left ventricular ejection fraction (LVEF), subjects will be allocated into two groups: with LVD (LVEF < 45%) and without LVD (LVEF > 45%). Patients will be submitted to the 6MWT and SWT linked to portable spirometric-telemetric device before and 6 days after CABG. During the first days after surgery, patients will be evaluated about pulmonary function and respiratory strenght at rest and oxygen consumption during the portable cycle ergometer protocol. Clinical outcomes as time to hospital discharge, pulmonary complications and occurence of arrythmias will be assessed during inpatient time until hospital discharge. Incidence of mortality, hospital readmission and angina recurrence will be evaluated in a one-year follow up.
BACKGROUND: The treatment with continuous glucose monitoring system (CGMS) offers improved glycemic control for patients with type 1 diabetes. However, patients with type 1 diabetes usually intake foods with sugar, even without hypoglycemic episodes, and the use of advanced carbohydrate counting method may increase the calories and carbohydrate intake. OBJECTIVE: To evaluate and compare the influence of sucrose-free diet or sucrose-added diet on glucose variability in patients with type 1 diabetes. METHODS: The study was a simple-blind, two-way crossover design in which patients with type 1 diabetes will receive a control diet (a diet with a little quantity of sugars) or test diet (with foods containing moderate quantity of sucrose in composition) during two-days each. During the intervention, all foods and drinks intake will have to be documented to allow quantitative estimation of dietary intake, to verify adherence to the diets. After one-week, each patient will return for download CGMS. PURPOSE: The research proposal adds knowledge about the glucose variability in patients with type 1 diabetes who use foods with sugar in theirs habitual dietary intake.
The purpose of this study is to assess the safety of RefortrixTM (Tdap) when administered during pregnancy in a maternal immunization program in Brazil.
Background: There is no consensus regarding the treatment of insertional tendinopathies. The good results of the eccentric training in the management of the non-insertional Achilles tendinopathy were not reproducible in the insertional disease. Shock wave therapy is described as an alternative to these patients. Hypothesis: The shock wave therapy allied to the eccentric strengthening protocol presents better results that the eccentric strengthening associated to placebo. Design: Double blinded (outcome assessor and patient) randomized clinical trial, with the use of placebo, in parallel groups. Materials and Methods: Nine-three patients with chronic insertional tendinopathy will be enrolled in a randomized trial. Participants will be divided in two groups, one containing the combination of shock wave and eccentric exercises as treatment and the other comprehending the exercises assembled to placebo. The assessment of outcomes will occur in 2, 4, 6, 12 and 24 weeks of the beginning of the study. Patients will be evaluated for pain, activity and function by the VISA-A (the Victorian Institute of Sport Assessment-Achilles [VISA-A] questionnaire).
The main purpose of this study is to evaluate the safety and efficacy of the study drug known as ixekizumab in biologic disease modifying antirheumatic drug (bDMARD) naïve participants with nonradiographic axial spondyloarthritis (nonrad-axSpA).
This was a Phase 3, multicenter, randomized, double blind, placebo-controlled study evaluating the efficacy and safety of venetoclax plus bortezomib and dexamethasone in participants with relapsed or refractory multiple myeloma who are considered sensitive or naïve to proteasome inhibitors and received 1 to 3 prior lines of therapy for multiple myeloma.
