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 purpose of this project is to compare the effectiveness between face-to-face consultations and consultations via videoconferencing among patients treated in the Institute of Psychiatry (IPq).
The purpose of this research study is to compare the effectiveness and safety of ABP 980 against trastuzumab in women with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer.
The study aimed to evaluate the use of exercise as a complementary strategy to treat severe major depression in inpatients. Hypothesis: Exercise can be used as a safe and efficacious complimentary strategy in severe depressed inpatients.
The aim of the study is to investigate the longterm impact on cardiovascular morbidity, mortality and renal function of treatment with linagliptin in a selected population of patients with Type 2 diabetes mellitus (T2DM) and to compare outcomes against placebo, on a background of standard of care.
The aim of the study was to evaluate the analgesic effect of transcutaneous electrical nerve stimulation High (100 Hz) and low (4 Hz) frequency in postpartum pain after cesarean section.
Although half of the patients with HF has normal ejection fraction or slightly altered (HF-PEF) and the prognosis differs little from those with reduced ejection fraction, the pathophysiology of HF-PEF is still poorly understood. Sodium restriction is the most common measure of self-care oriented to HF patients for management of congestive episodes. The role of this orientation in the treatment of patients with preserved ejection fraction, however, is still unclear. The evaluation of the effects of sodium restriction on neurohormonal activation and episodes of decompensation in HF-PEF can promote a better understanding of the pathophysiological progression of this complex syndrome.
Climacteric or Menopausal Transition is defined as the time period where there is a change to non-reproductive reproductive life, with extension of variable length. During this period, and after the establishment of Menopause and non-functioning ovarian, the appearance of various symptoms that express the depletion of ovarian follicles is common; among these symptoms, the most frequently reported by women are vasomotor symptoms or hot flashes. In addition to hormonal therapy, other medications have been employed in an attempt to improve these symptoms; although they present better results than placebo, yet have little clinical impact in reducing vasomotor symptoms. Therefore, this gap allows the evaluation of alternative therapies, such as Transcranial Direct Current Stimulation (tDCS). The rationale for studying the effect of this technique in this context is its possible autonomic modulatory effect. What reinforces the choice of this technique is the fact that it demonstrated efficacy in other pathologies such as depression, pain, Parkinson's disease, among others. Transcranial direct current stimulation (tDCS) is a renewed method of non-invasive brain modulation. It is based on a transcranial application of weak direct currents in a non-invasive, simple and painless manner. Its use in the treatment of vasomotor symptoms has not been studied. The objective of this study is to evaluate the improvement of vasomotor symptoms in postmenopausal women, after application of tDCS, and compare them to a control group. This Randomized Clinical Trial will be held in female postmenopausal patients, followed in the outpatient Menopause Clinic of Obstetrics and Gynecology Service, Hospital de Clinicas de Porto Alegre. From these results, it is expected to present a new therapeutic option in the treatment of vasomotor symptoms.
Obstructive sleep apnea and hypertension are well-known cardiovascular risk factors. Their control could reduce the burden of heart disease across populations. There are several drugs to control hypertension, but the only consistently beneficial treatment to reduce apneas is continuous positive airway pressure. The demonstration that one drug could improve sleep apnea and hypertension would support a novel approach in the treatment of both diseases. The role of fluid retention in sleep apnea is known for several decades. The role of diuretics is well established in hypertension but was never appropriately tested in sleep apnea. Besides to test the efficacy of these drugs, this study will help to understand the mechanisms that link hypertension and sleep apnea and its treatment.
The purpose of this study is to evaluate the efficacy of brain and peripheral electrical stimulation on chronic non-specific low back pain patients.
The purpose of this study is to evaluate the efficacy and safety of sublingual zolpidem presentation 5 mg in the induction of sleep in patients with primary insomnia.
