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.
Randomized prospective clinical trial, aiming to compare two techniques of orbital decompression. Patients with Graves orbitopathy in the inactive phase for at least 6 months will be divided in two groups; one group will be submitted to orbital decompression by antro-ethmoidal technique; the other group will be submitted to orbital decompression by lateral wall technique. Patients will be followed up for a period of 6 months after the surgery, and will be evaluated about the effect of orbital decompression on ocular motility, proptosis, ocular surface and quality of life.

The purpose of this study is to show that subcutaneous (SC) administration of daratumumab co-formulated with recombinant human hyaluronidase PH20 (Dara SC) is non-inferior to intravenous (IV) administration of daratumumab (Dara IV) in terms of the overall response rate (ORR) and maximum trough concentration (Ctrough).
The purpose of this study it to compare the efficacity of isatuximab when combined to carfilzomib and dexamethasone versus carfilzomib and dexamethasone in patients with multiple myeloma already treated with 1 to 3 prior lines of therapy.
PURPOSE: To evaluate the efficacy of shock waves extracorporea in improving body contour,decrease fat localized and appearance of gynoid lipodystrophy. SUBJECTS AND METHODS: A prospective and comparative longitudinal clinical study will be performed in 30 women with localized fat and gynoid lipodystrophy. Patients will be submitted data collection and assessments and before and after treatment. HYPOTHESES: It is expected that the patients will present improvement in the body contour, decrease fat localized and in the picture of the gynoid lipodystrophy after of the therapies. STATISTICAL ANALYSIS: A descriptive analysis will be done before and after vibration-oscillatory therapy, with frequency tables for categorical and descriptive variables (mean, standard deviation, median, minimum and maximum values) for continuous or numerical variables. In order to compare the main variables between the groups and the collection times, the analysis of variance (ANOVA) for repeated measurements will be used. Tukey's test will be used to compare groups. The level of significance adopted for the statistical tests will be 5% or p <0.05.
Conventional hemodialysis (HD) is essential for the treatment of end-stage renal disease (ESRD) patients, by reducing serum concentration of uremic toxins and correcting fluid overload. Nevertheless, HD removes almost exclusively low-range uremic toxins. Therefore, medium-range molecules, such as beta-2-microglobulin might accumulate in tissues, leading to many clinical complications, such as neuropathies, tendinopathies, anemia, bone mineral disease and reduced growth in children. Convective methods might reduce incidence of these complications, by removing molecules of medium-range molecular weight. Online hemodiafiltration (olHDF) is the most extensively used method in this regard. Nevertheless, there are some barriers to the wider introduction of this method in clinical practice, since specific machines are needed for this procedure, the costs with dialysis lines are higher and water consumption increases. More recently, the development of new membranes for hemodialysis allowed removal of medium- and high-range uremic toxins, with albumin retention. Thus, they allow removal of a broad range of uremic toxins, without changing dialysis machine or increasing water consumption. Such therapy is known as expanded hemodialysis (HDx). The aim of this present study is to compare the extraction of middle-size molecules, the hemodynamic behavior, fluid and nutritional status of patients submitted to olHDF or HDx, in a crossover study.
This Phase III, randomized, double-blind, placebo-controlled study will compare the efficacy, safety, and pharmacokinetics of polatuzumab vedotin plus R-CHP versus R-CHOP in participants with previously untreated diffuse large B-cell lymphoma (DLBCL).
The objective of this study was to evaluate the effect of a physical exercise program on the functional capacity of children and adolescents with cystic fibrosis hospitalized at the Hospital de Clínicas of Porto Alegre (HCPA) through a six-minute walk test using the distance traveled In six minutes. In the first 48 hours of hospital stay, the following evaluations will be performed: Six-minute walk test, physical and health fitness test, spirometry and data collection. Patients will be randomized to either control group or intervention group. The control group will receive the conventional treatment offered by hospital care, the intervention group will receive this same treatment plus an exercise protocol. After 14 days they will be reevaluated with the same tests applied at the beginning of hospitalization.
Historically, adults and children who undergo elective surgery remain fasting in the preoperative period, for the purposes of avoiding bronchial aspiration of the gastric contents during general anesthesia. The determination of preoperative fasting has taken on importance only in 1946, when Mendelson established a relationship between pulmonary aspiration during labor and general anesthesia. Stemming from other studies, such concept has been expanded to elective surgery and 25 ml were set as the maximum threshold of the gastric content to thus reduce the hazards of aspiration pneumonia. The fasting time prescribed is still the subject of several investigations. For decades it has been established that patients should not feed on solids or ingest liquids over a period of 8 to 12 hours prior to surgery. The guidelines are well set in connection with the rules of fasting, with aims at making the instructions constant throughout different services worldwide. In 2011, the American and the European guidelines became more permissive and determined as safe the 2 hours for liquids devoid of residue, 4 hours for breast milk, 6 hours for infant formula and non-human milk, 6 hours for light meals, and 8 hours for full meals. In accordance with the American guideline, liquids devoid of residue are: water, fruit juice with no pulp, carbohydrate-based beverages, tea with no residue, and black coffee, but those examples are not extensive. Gelatin is solid prior to intake, but it is found in a liquid state inside the stomach and, therefore, it is regarded as a liquid devoid of residue. Yet, in spite of the non-human milk's being a liquid material, it features a gastric emptying time which is similar to that of the non-fat solids. A light meal is characterized by toast and liquids devoid of residue, whilst a full meal includes food that is fried or which contains a high level of fat. Currently, many directives (American Society of Anaesthesiologists - ASA; Norwegian National Consensus Guideline - NNCG; Association of Anaesthetists of Great Britain and Ireland - AAGBI) recommend liquids devoid of residue until two hours prior to the anesthetic induction for elective surgery in healthy children. The particular benefit of the oral intake of fluids includes a lower incidence of deleterious effects, such as thirst, irritation, crying, hypoglycemia, and dehydration. The preservation of the intravascular volume improves the hemodynamic conditions during the induction of inhalation anesthesia and facilitates the vascular access. Even though the old instruction of "nothing by mouth after midnight" is in a process of being replaced by shorter periods of fasting, both surgeons and anesthesiologists still deem the traditional fast indispensable and have trouble with implementing the new norms, either by uncertainty before the possibility of the catastrophic consequences of pulmonary aspiration, or by lack of update on the subject. That matter generates mistakes in the rendering of information by the health professionals. Combined with the unawareness of the guardians in respect of the risk of bronchial aspiration and the anxiety in relation to the fasting, there is a result of difficulty in abidance by the proper preoperative fasting. The minority of the guardians understands the real importance of the preoperative fasting and, many times, food regarded as "harmless" is offered during the period of fasting. Likewise, the guardians provide improper information in order to maintain the surgical procedure, with no regard for the correct observance of the fasting. That way, countless pediatric elective surgeries are canceled, deriving in psychological, social, and economic implications. The correction of these flaws will allow for the anesthetic procedure to take place in a more secure manner, with the proper observance of the fasting period and with the least possible trauma to the child.
