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.
The hypothesis of this study is that thoracic spine manipulation would reduce pain in subjects with SIS and cause changes in scapular kinematics and muscle activity in subjects with impingement symptoms and in asymptomatic subjects. With this study, the investigators want to answer if possible changes in scapular motion and muscle activity following a TSM depend on the symptoms or if it is generic to individuals without shoulder dysfunction and not specific to subjects with shoulder impingement.
To evaluate the influence of different types of ankle taping in dynamic equilibrium and the electrical activity of the support member during the sporting gesture kicking muscles.
The objective was to compare the frequency and intensity of symptoms of anxiety in patients of preoperative cardiac surgery who received empathic behaviour from nurse or family or those who received no specific type of empathic behaviour. This is a randomized clinical trial. The sample consisted of 66 patients in preoperative of cardiac surgery, who were divided in three groups: empathic behaviour by nurses, without specific empathic behaviour and by family. Anxiety was assessed at two time points: before and after the intervention. The instrument used was developed and validated, comprising 19 defining characteristics of the nursing diagnosis anxiety. The hypothesis is that the group who received empathic behaviour from nurse or family will reduce the anxiety.
The aims of this study are examine the effects of sleep deprivation in muscle recovery after a maximum eccentric resistance exercise session performed on an isokinetic dynamometer (24 series of 10 repetitions). The sample will consist of 10 men, sedentary, clinically healthy, aged between 20 and 31 years old. Two experimental groups will be developed: EXE-SLEEP, in which subjects will perform the exercise protocol (~18:00-19:00) and will be subject to normal period of sleep for 3 nights; EXE-TOTAL, in which subjects will perform the same exercise protocol and will be sleep deprived for 60 hours, followed by one night of sleep rebound.
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
Radiotherapy is a treatment considered standard for non melanoma skin cancer. This institution uses schemes of 4 to 6 weeks of treatment. The objective of the study is to perform radiation therapy in 1 to 2 weeks, depending on the size of the lesion.
Brain metastases occur in 20-40% of patients with metastatic cancer. The standard treatment is based on whole brain radiation therapy and local treatment of metastases as neurosurgery or radiosurgery. However, many cases can not receive a standard local treatment, and local relapse occurs in almost 50% of cases treated with only whole brain irradiation. There are retrospective studies of increased radiation dose at the site of metastasis with hypofractionated stereotactic radiotherapy (HSRT) with favorable results, but there are no controlled studies regarding the safety of radiation dose in these situations. This study is a phase I study to evaluate the maximum tolerance dose (MTD) with HSRT as a way to increase the dose of radiation after the WBRT for patients with 1-3 brain metastases not eligible for surgery or RS.
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.
