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.
Metabolic disorders and malnutrition are well known and have been reported in patients with chronic liver disease, but the relationship of energy metabolism and changes in nutritional status in patients on the waiting list for liver transplantation are unexplored. The aim of this study was to assess the resting energy expenditure (REE) of these patients, identifying the prevalence of hyper and hypometabolism. In addition, to assess if, malnutrition and clinical variables were associated with REE and metabolic disorders.
Background: Physicians´ lack of knowledge contributes to underuse of insulin and poor glycemic control in adults with diabetes mellitus (DM). Traditional continuing medical education have limited efficacy, so new approaches are required. Objective: We report the design of a trial to assess the educational efficacy of InsuOnline©, a game for education of primary care physicians (PCPs) on initiation and adjustment of insulin for the treatment of DM, which was designed to be: a) educationally adequate; and b) self-motivating and attractive. Methods: A multidisciplinary team, with endocrinologists, experts in medical education, and programmers, was assembled for design and development of InsuOnline©, a serious game which includes game elements and a well-defined, evidence-based curriculum of topics on insulin therapy. The first step of our study will be usability and playability tests, with PCPs and medical students, playing the game on a desktop. After that and further adjusts, we will perform an unblinded randomized controlled trial, with PCPs who work in the city of Londrina, to assess the educational validity of the game. A group of 64 PCPs will play InsuOnline© on the web, and the control group, of 64 PCPs, will underwent traditional teaching activities (lecture and group discussion). Knowledge on how to initiate and adjust insulin will be assessed by a web-based multiple-choice questionnaire, and attitudes regarding diabetes/insulin will be assessed by Diabetes Attitude Scale 3, at 3 time points: before, immediately after, and 6 months after the intervention. Subjects´ general impressions on the interventions will also be assessed by free-text questions. Software logs will be reviewed.
Bariatric surgery is the only satisfactory treatment for loss and weight maintenance in obese patients. This loss is a result of several factors that go beyond the simple anatomical abnormality of the gastrointestinal tract and may be the product of post-op energy expenditure changes. The respiratory quotient (RQ) and diet-induced thermogenesis (DIT) are important components of energy expenditure and possible changes in them can perform an important role in weight loss after Roux-en-Y Gastric Bypass (RYGB). Previously, we conducted a cross-sectional study where we measured the RQ and DIT in pre and post-op RYGB patients, which was published in the Surgery of Obesity and Related Diseases (SOARD) journal. The objective of this study is to perform a prospective analysis of these same variables (RQ and DIT), evaluating them in the same patients, when pre and postoperatively.
The purpose of this study is to compare the oxygen consumption and energy expenditure during the spontaneous breathing trial.
OBJECTIVE: To analyze the influence of lipid control during a cardiorespiratory exercise test in two subgroups. DESIGN: Parallel trial study. PARTICIPANTS: The sample consisted of 40 elderly people, male and female, divided into two groups: 20 hypertensive (G1; 68.50 ±5.85 years) and 20 diabetic-hypertensive (G2; 68.95 ±6.79 years). MEASUREMENTS: Nutritional status; glucose and lipid controls - postprandial glucose (PPG), triglycerides (TG), total cholesterol (TC), low density lipoprotein (LDL-C), very low density lipoprotein (VLDL-C), high density lipoprotein (HDL-C); blood pressure, and cardiorespiratory performance. The significance level was set at p<0.05.
The purpose of this study is to determine if tivantinib (ARQ 197) is effective in treating patients with MET diagnostic-high hepatocellular carcinoma (liver cancer) who have already been treated once with another therapy.
The purpose of this study is to evaluate efficacy of orlistat 60 mg as adjuvant treatment of Obesity in adults.
Objectives: to evaluate xerostomia and salivary flow in patients with burning mouth syndrome (BMS) treated with amitriptyline before and after the use of antixerostomic topical medication. Methods: In this case-control double-blinded study, we enrolled 38 patients with BMS diagnosed according to the (IASP). The subjects were randomly divided into two groups: Study Group: 19 patients whom received topical medication of urea 10% and Control Group: 19 patients whom received placebo to apply at the oral cavity 3-4 times per day, during three months. The patients were evaluated before and after the above treatment. Finally, data were statistically analyzed. It is know that BMS is eventually associated to reduced salivary flow (Cho et al.,2010; Kho et al., 2010; Marino et al., 2010) and to abnormal salivary composition (increasing concentrations of K+, Na+, Cl-, Ca+2, IgA, amylase) (Patton et al., 2007). Even in the absence of hyposalivation, patients may complain of xerostomia and dry mouth (Cho et al.,2010; Kho et al., 2010; Marino et al., 2010; Thomson, 2005). These patients also have several sensory losses even in taste and smell function, recently described (Siqueira et al., 2006a; Siqueira et al., 2006b; Siviero et al., 2011).
Watching football matches could cause increased blood pressure and heart rate induced by catecholamines and thus increase the incidence of cardiovascular events. However, no studies have evaluated the responses of blood pressure and heart rate in soccer spectators. This study evaluates the hemodynamic response in Brazilian soccer fans suffering from coronary artery disease during a dispute over a game of your favorite team.
To assess the usefulnes sof misoprostol versus placebo (in a double-blind placebo controlled randomized clinical trial)to facilitate the insertion of copper-IUD and the levonorgestrel-releasing intrauterine system (LNG-IUS) in cases of failure due to cervical stenosis in either nulligravidas and parous women. Additionally to evaluate the side-effects of the misoprostol. The hypothesis is that misoprostol may be better than placebo.
