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.
To determine whether a comprehensive evaluation and customized multilevel educational interventions will increase the rate of use of oral anticoagulants and the adherence and persistence of use in patients with atrial fibrillation. Our hypothesis is that there will be differences in the use of oral anticoagulants and the persistence in patients between the control and interventional group. There will be a greater change in the use of oral anticoagulants over one year in the cohort in the intervention sites than the control sites. This will be due to two factors: greater initiation of oral anticoagulants among patients not treated at baseline and greater persistence of treatment for those on treatment at baseline
To evaluate the long-term safety and tolerability of idalopirdine (Lu AE58054) as adjunctive therapy to donepezil in patients with mild-moderate Alzheimer's Disease (AD).
This study aims to determine changes in cerebral blood flow of people with obesity after the ingestion of fat.
Radiographs have been used to aid dentists in detecting the presence of cavities in the deciduous teeth of children. This procedure is globally recommended because the conventional clinical examination usually overlooks some cavities. However, the real benefit of performing dental radiographs for this purpose is still unclear. Besides the hazards of ionizing radiation, the radiographs could provoke overtreatment of the children; hence, dentists would tend to restore more teeth than would be really necessary. Nowadays, it is preferable to overlook some cavities than treat the teeth unnecessarily. Therefore, the investigators aimed to perform this study to compare two different strategies for detecting cavities in deciduous teeth of children: one based on clinical examination performed alone and other using radiographs adjunct to the clinical examination. To compare these strategies, the investigators will consider outcomes related to children's health and welfare.
The purpose of the study is to document the natural history of hemophilia A disease and long-term outcomes in terms of effectiveness, safety and quality of life in participants receiving Antihemophilic Factor (Recombinant) - Plasma/Albumin Free Method (rAHF-PFM) or Antihemophilic Factor (Recombinant) - Pegylated (rAHF-PEG) in routine clinical practice
This is a pilot study which aims to show the temperatures measured on body surface with an infrared thermometer on inpatients who need a central venous catheter (CVC) for medical care. Because the local temperature could be altered, at least during local infectious processes, seems to be reasonable to think that this approach could be helpful to its early diagnosis.
Evaluate the correlation between the structural changes of fractures of the thoracic and lumbar spine burst type with clinical outcome of the treatment.
General Objective: To evaluate the swallowing results of speech pathologist rehabilitation of advanced oropharynges, larynx and hypopharynx cancer patients during neoadjuvant chemotherapy and radiotherapy concomitant to chemotherapy. Methods and Casuistic: Randomized clinical trial phase II. 80 patients with advanced oropharynges, larynx and hypopharynx cancer diagnoses from Barretos Cancer Hospital, which had the proposal of neoadjuvant chemotherapy followed by radiotherapy combined with chemotherapy. Patients are randomized on two groups: control group and speech pathology therapy group
The purpose of this study was to evaluate the potential reorganization in the sensorimotor cortex in spinal cord injury (SCI) patients after Body Weight Supported Treadmill Training (BWSTT) associated with conventional motor rehabilitation. The investigators hypothesized that training with weight bearing associated with conventional motor rehabilitation will be able to reorganize the brain.
Design: Observational - Cross study with followed up for 30 days. The Primary Objective is to realize a record that reflects a national overview of the role of cardiac catheterization in patients with congenital heart disease in hospitals distributed by geographic density of each region of Brazil.
