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.
Patients after the Fontan operation at a single institution will be randomized to receive a standardized extract of Aesculus hippocastanum L. (horse chestnut) or placebo for 4 months in a crossover clinical trial. The primary outcome will be the mesenteric artery resistance measured by Dopple sonography.
Obesity is a complex disease associate to metabolic alterations, which may lead to cardiometabolic risk in women with obesity. The use of interactive digital technology as adjuvante tool to the clinical practices in weight loss therapy emerges as an innovative strategy. However, it was note fully investigated if this kind of approach can contribute to improve inflammatory state and metabolic alterations in obese population.
This additional arm of the DESolve Nx study is an evaluation of the CE Mark approved DESolve Cx Novolimus Eluting Bioresorbable Scaffold System.
This study compares two types of noninvasive treatments for asthma attacks with the objective of analyzing the efficacy of each therapy during the period of exacerbations in infants and asthmatics hospitalized.
Th objectives of this study are: - To determine the performance of G6PD tests in detecting G6PD activity and hemoglobin (Hb) compared to a reference assay - To assess the comprehension of the G6PD test packaging and labelling among intended users - To assess the usability of G6PD test result outputs among intended users
The purpose of this study is to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active ulcerative colitis (UC).
Stroke is characterized by poor brain perfusion resulting from an ischemic or hemorrhagic event, causing a sensorimotor disorder in the upper extremity (UE) contralateral to the lesion. Mirror Therapy (MT) has been used in rehabilitation and its effects are related to the activation of mirror neurons and cortical reorganization. However, few studies have investigated the isolated effect of MT on the rehabilitation of these individuals. Objective: To investigate the isolated effect of MT on motor function, sensitivity, muscle strength, manual dexterity and spasticity of the paretic UE of individuals with chronic hemiparesis after stroke. Design: Randomized simple-blind trial. Subject: Twenty-six patients post chronic, aged between 30 and 80 years, with mild or moderate sensorimotor impairment in UE will be evaluated. Intervention: The subjects will be randomly distributed in: intervention group will perform 60 minutes of MT and the control group will perform 60 minutes of control therapy composed of the same exercises, but without the mirror. Both groups will hold two sessions per week for six weeks. Main measure: Participants will be evaluated before and after the intervention. They will be evaluated through the Fugl-Meyer Scale to measure UL sensorimotor performance, Box-and-Block Test for manual dexterity, Dynamometry for palmar grip strength and Modified Ashworth Scale for spasticity. With this study, it was expected that the intervention group presented better results regarding the sensorimotor function when compared to the control group. The data will be expressed as mean and 95% confidence interval (continuous variable) and absolute frequency (categorical variables). To compare the outcomes of the different experimental sessions and at the different moments (pre and post session), the Generalized Estimating Equations with post hoc LSD (Least Significant Difference) methods will be used. For all analysis the significance level was set at α = 0.05 and statistical software SPSS (Statistical Package for Social Sciences for Mac, version 22.0, IBM, USA) will be used.
This study evaluates the use of photobiomodulation in the treatment of patients with Parkinson's disease. Half of participants will receive treatment with low level laser therapy and exercises in combination, while the other half will receive a placebo laser combined with exercises.
Blood pressure control is crucial for individuals' wellbeing. However, many daily aspects such as diet could impair blood pressure control. In addition, many people living under different conditions in different countries are affected by some kind of gum disease. These people experience gingival bleeding, bad breath, teeth mobility and pain. Throughout gum disease development the number of oral germs in the mouth increases including their levels in tongue surface. Oral bacterial are able to convert nitrate widely found in food in nitrite which influences blood pressure. Frequently treatment of gum diseases general combines manual instrumentation with mouthwashes. However, it has been suggested that reduction of oral bacteria by mouthwashes, especially chlorhexidine, is accompanied by decreased conversion of nitrate to nitrite and that this minor nitrite availability would increase blood pressure. Therefore, this is a point to be clarified for patients, physicians and dentists. This study will investigate the relation between treatment with mouthwashes and blood pressure of patients with destructive gum disease based on nitrite levels in saliva, bacterial levels in tongue and values of arterial blood pressure which will be monitored over 6 months. In addition, usual clinical parameters and alteration of oral cells' DNA will be also monitored overtime. Patients will be treated under local anesthesia and manual instrumentation within 24 hours. They will receive oral care products too. There will be 3 treatment groups (manual instrumentation + chlorhexidine mouthwash [2 times a day for 3 weeks], manual instrumentation + placebo mouthwash [2 times a day for 3 weeks] and manual instrumentation + no mouthwash) and 2 dental appointments before treatment. After treatment, patients will be examined at 7, 14, 21, 90 and 180 days. Saliva, plaque and cell sampling will be fast and by no invasive methods.
The primary purpose of the study is to compare the effectiveness of nivolumab plus concurrent chemoradiotherapy (CCRT) followed by nivolumab plus ipilimumab vs CCRT followed by durvalumab in participants with untreated Locally Advanced Non-small Cell Lung Cancer (LA NSCLC).
