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.
Obesity is a worldwide epidemic with increasing prevalence, specially severe obesity (Body Mass Index (BMI) ≥ 35 kg/m2). It is a multifactorial disease that involves genetic and environmental factors that lead to increased mortality from cardiovascular disease, diabetes, cancer, among others and impairs life quality. Most research on severe obesity focuses on surgical alternatives and their results, thus this clinical trial aims to evaluate the effect of a non-pharmacological approach based on nutritional intervention and supplementation with a functional food, the olive oil. It will analyze the effectiveness of interventions on: weight loss, improvements on body composition and inflammatory profile (TNF-alfa, interleucins 1, 6 and 10, adiponectin), insulin resistance and serum lipids control, changing eating habits and physical activity practice, modification on bone mineral density and sarcopenia, and reduction of cardiovascular risk and other diseases. Also, it will be investigated the influence of polymorphisms (Pro12Ala of PPAR-γ gene, -174G>C of IL6 gene e Trp64Arg of ADRB3 gene) on nutritional intervention effectiveness with and without olive oil. This research looks for improving severely obese patient's care and contributing to effective results by reducing costs and risk treatment. The investigators believe that this informations will contribute significantly to the scientific field, expanding the knowledge about severe obesity.
This is a safety and efficacy study of abicipar pegol in participants with neovascular age-related macular degeneration.
This study aim is to determine the efficacy of two Oral Hygiene Regimens in the reduction of dentin hypersensitivity on subjects undergoing non-surgical periodontal treatment, over a period of 8 weeks.
The aim of this study will be evaluate clinically the use of the Semilunar Coronally Positioned Flap (SCPF) for the treatment of gingival recessions, with or without Enamel Matrix Derivative (EMD). Thirty patients will be assigned in two groups. Half of patients will receive EMD associated to SCPF, while the other half, will receive SCPF alone.
The inspiratory muscle training (IMT) is a feasible and safe strategy for patients and athletes, your goal is to recondition the respiratory muscles, providing optimization of lung capacity, either for high performance sport as to support metabolic wear caused by illness. It is generally agreed the positive impact of the application of a TMI Protocol on maximal inspiratory pressure (MIP), this benefit encourages individuals sick since weaning from mechanical ventilation (MV), to the optimization of physical performance in cardiac and / or pulmonary rehabilitation. The TMI is based on the principles: the burden imposed on the muscle; the specificity of training; the reversibility of the gain and muscle atrophy.
The primary efficacy objective for this study is to evaluate non-progression rate (NPR) at 18 weeks in participants with advanced solid tumors treated with atezolizumab, defined as the percentage of participants with complete response (CR), partial response (PR), or stable disease (SD) as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) Version (v) 1.1, or according to disease-specific criteria for prostate cancer and malignant pleural mesothelioma.
The purpose of this study is to evaluate the reduction of gingival recession of single Miller Class I and II defects treated by coronally advanced flap with subepithelial porcine collagen matrix graft and / or enamel matrix proteins.
The aim of the study is to perform a three-dimensional (3D) evaluation of the dentoskeletal changes in pubertal Class II malocclusion subjects treated with the Herbst appliance (HAG), in comparison with a Class II comparison group (CG). 3D virtual models generated from three time-point CBCTs (T0, baseline; T1, immediately after Herbst insertion; and T2, 8 months after) of 25 HAG patients will be evaluated. Virtual models obtained from 25 Class II malocclusion patients, in the same stage of biologic maturation and skeletal abnormality, but with no orthopedic treatment will be constructed for the CG subjects. These CG patients are under orthodontic treatment, but only with teeth alignment. Voxel based registration on the anterior cranial fossa will be used to assess maxillary and mandibular displacement/articular fossa remodeling; regional registration on the mandibular corpus will be performed to evaluate mandibular growth and mandibular dental changes; and regional registration on the anterior region of the maxilla will be performed to evaluate maxillary growth and maxillary dental changes.
This study is a randomized clinical trial with two interventions: control group and intervention interdisciplinary group, without cross-over. Control Group (CG): In this type of intervention, the focus will be the development of skills through educational activities on health using the pedagogy of transmission. Interdisciplinary Intervention Group (IG): In this type of intervention, the focus will be the development of skills through educational activities on health that provide the development of autonomy and empowerment for behavior change, based on interdisciplinary motivational strategies. All topics will be focused on the major cardiovascular risk factors considered modifiable. The staff is trained to the techniques of motivational interviewing and transtheoretical model of change and the health issues related to the modification of lifestyle. So this interdisciplinary intervention with adolescents seeks to measure the result of an educational proposal using the techniques of motivational interviewing and transtheoretical model of change, for all professionals involved independent training in health issues related approach to lifestyle modification and the inclusion of family in this process.
Stroke is the second cause of death worldwide and represented the first cause of death in Brazil between 2006 and 2010. Most patients survive, and there is a need to develop cost-effective rehabilitation strategies to decrease the burden of disability from stroke. This study addresses this important issue, by evaluating, in the early phase post-stroke, effects of motor conventional physical therapy associated or not with transcranial direct current stimulation (tDCS).
