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 demonstrate the functional results of patients with ankle fractures operated with arthroscopic deltoid repair.
This study aims to discover whether acquiring basic-literacy in adulthood can improve episodic memory and brain structural and functional connectivity. In a collaborative project between Brazil and USA, the investigators will use a randomized controlled trial approach to leverage the level of evidence of the benefits of basic adult-education as a possible cognitive reserve builder. If successful, the study's findings will be important in shaping policies targeting increasing access to late-life education to reduce dementia risk.
This study is being conducted to better understand the natural course of GM1 gangliosidosis, GM2 gangliosidoses and Gaucher disease Type 2 (GD2). Information is planned to be gathered on at least 180 patients with GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2. Retrospective data collection is planned for at least 150 deceased patients (Group A). Group B is for patients alive at the time of enrollment. In Group B it is planned to prospectively collect more comprehensive data from at least 30 patients. The purpose of this study is to collect relevant information for a adequate design of a potential subsequent research program in these diseases. In this study no therapy is being offered.
The purpose of this study was to access the possible beneficial effects of oral use of pilocarpine in relieving signs and symptoms of patients with Sjogren's syndrome
Stroke is the leading cause of disability in developed countries, and the major cause of mortality in Brazil.It is associated with low quality of life, disability, decreased muscle strength and control due to the hypertonia, spasticity. These pathways can develop inadequate upper and lower limbs functional mechanisms. These changes are linked with disabilities and painful syndromes. The shoulder pain relationed after stroke has a variable prevalence from 16 to 84%, from mild to severe pain and is relationed as a precursor factor of secondary deformities, depression, longer hospital stay. Its etiology remains controversial with many possibilities as rotator cuff injuries, glenohumeral dislocation, impact syndrome, bicipital tendinitis, hand shoulder syndrome, myofascial painful syndrome, presence of spasticity and contractures, adhesive capsulitis, central pain and others. Its management is controversial and could be done with physical therapy (kinesiotherapy) intra-articular or local injections (muscles and nerves), functional electrical stimulation, acupuncture, herbal medicine, tapping, myofascial painful syndrome treatment, painkillers, anti-inflammatories and antispastic drugs like botulinum toxin A - tested in few studies, case series, against corticosteroids. The aim of this study will be to evaluate the effectiveness of the use of 200 units of abobotulinumtoxin against placebo in both pectoralis major and subscapularis: for reducing shoulder pain (Visual Analogue Scale, McGill pain scale), active and passive range of motion(goniometer),upper limb function (Fugl-Meyer test), burden of care questionnaire (apply to caregivers). This study is designed as a prospective, double-blind, randomized, controlled study in two Rehabilitation Centers (Rehabilitation Center from Santa Casa de São Paulo and Hospital de Clínicas of Universidade de Sao Paulo - Ribeirão Preto).
The number of COVID-19 cases has been growing exponentially, so that the industrialized economies are facing a significant shortage in the number of ventilators available to meet the demands imposed by the disease. Noninvasive ventilatory support can be valuable for certain patients, avoiding tracheal intubation and its complications. However, non-invasive techniques have a high potential to generate aerosols during their implementation, especially when masks are used in which it is virtually impossible to completely prevent air leakage and the dispersion of aerosols with viral particles. In this context, a helmet-like interface system with complete sealing and respiratory isolation of the patient's head can allow the application of ventilatory support without intubation and with safety and comfort for healthcare professionals and patients. This type of device is not accessible in Brazil, nor is it available for immediate import, requiring the development of a national product. Meanwhile, a task force under the coordination of the School of Public Health (ESP) and Fundação Cearense de Apoio à Pesquisa (FUNCAP), with support from SENAI / FIEC and the Federal Universities of Ceará (UFC) and the University of Fortaleza (UNIFOR) advanced in the development of a prototype and accessory system capable of providing airway pressurization through a helmet-type interface, which was called the Elmo System.

The main objective of this study is to evaluate the efficacy of danicopan as add-on therapy to a complement component 5 (C5) inhibitor (eculizumab or ravulizumab) in participants with PNH who have clinically evident EVH.
Tofacitinib suppresses pro-inflammatory signaling that may be important pathogenetically to progression to more severe lung disease and acute respiratory distress syndrome (ARDS) in patients with COVID-19. The purpose of the study is to assess the safety and efficacy of tofacitinib plus standard pharmacologic and supportive measures in treating hospitalized participants with COVID-19 pneumonia.
Myelomeningocele is a malformation with high incidence, and it consists in a neural tube defect. Fetal intrauterine surgery is an alternative for correction, and it improves the prognosis of the fetus, but has an increased risk of maternal complications and premature labor, as it can occur due to uterine stimulation. It is therefore essential that tocolysis is performed before, during and after surgery, and the most commonly used tocolytics are terbutaline and atosiban. Terbutaline has no specificity and may have several adverse effects such as maternal acidosis.
