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.
Background: Over the last several years, there has been an increase in the popularity and availability of mobile digital technologies. Many recent studies have evaluated a range of mobile digital mental health interventions (DMHIs). Smartphone applications, remote monitoring, tracking devices, and wearable computers such as smartwatches and virtual reality headsets are being widely used for these studies. Besides that, psychometric scales are being used to help psychiatrists to improve treatment outcomes. The systematic administration of symptom rating scales and other assessment tools to help treatment decisions has been called measurement-based care (MBC) and it has shown good results in improving outcomes and time to response/remission of psychiatric diseases. As there is little data regarding MBC in Generalized Anxiety Disorder (GAD), the investigators decided to put technology and MBC together to study an easy and accessible way to improve the GAD usual treatment. Objectives: The aim of this study is to evaluate the benefit of digital interventions as an add-on tool to "treatment-as-usual" (TAU) in GAD patients. Methods: A twelve-weeks randomized clinical trial will be performed with 60 GAD patients. The control group will receive TAU, defined as 30-minutes online consultation with a trained psychiatrist, consisting in symptoms evaluation, general orientations about the disorder and use of medication. The consultations are going to occur biweekly. The digital intervention group (active group) will receive TAU, associated with two digital tools. The first one consists of psychoeducational videos to be seen between the sessions and the second one includes self-application of GAD-7 scale the day before the next scheduled consultation. All these digital interventions are going to be accessed in a mobile application, called "+PSI", that is already available in Apple Store and Google Play. The participants are going to be instructed to download the application on their mobile phones for free. The videos are going to be created especially for this project and will use animations and educational content, being of short duration (average 3 minutes). GAD-7 scale, and Hamilton Anxiety Scale (HAM-A) are going to be applied at baseline and at the end of the follow up by a blind rater. The investigators are also going to test the application tools usability using the System Usability Scale (SUS). Intermediate and follow-up evaluations will be performed to assess the speed and maintenance of improvement, respectively.
Continuous positive airway pressure (CPAP) with a helmet-like interface has been described as a safe strategy, with minimal contamination of the environment, improving the oxygenation of patients with acute respiratory failure (ARF) by COVID-19, avoiding intubation in more than half of the cases. ELMOcpap, developed in Ceará, was a great ally in the treatment of these cases during the pandemic in the state. It is estimated that among public and private services, more than 1.400 ELMOs have been applied to patients with COVID-19. However, the determining factors of the success and failure of its use in the different institutions in which it has been applied are still unknown. Therefore, it is necessary to survey all data associated with the use of the device. Objectives: 1. To describe the effects of ELMO in the treatment of patients with hypoxemic respiratory failure due to COVID-19 in a database, in a systematic and standardized way, on clinical history, efficacy, safety, modes, duration of use, the occurrence of adverse events and early predictors of failure. 2. Determine the intubation rate of patients with COVID-19 hypoxemic respiratory failure who used the ELMO. 3. Identify the mortality rate of patients with hypoxemic respiratory failure due to COVID-19 who used the ELMO. Methods: This is a retrospective, multicenter, observational, cohort study of recorded data from patients with COVID-19 hypoxemic respiratory failure who were treated with the ELMO. An online electronic form will be developed with REDCap, where the responsible investigator of each institution will be responsible for filling in the participants' data, ensuring adherence to the protocol and analysis will be carried out of the data of the patients of the participating services of the research that used the ELMO as treatment.
The aim of this randomized controlled trial is to analyze the effect of the SARAH protocol, which is a set of exercises with components of muscle strengthening, range of motion gain and home exercises, combined with an educational intervention, on hand function in women with rheumatoid arthritis (RA).
The objective is to evaluate in adult patients with chronic kidney disease the effect of neuromuscular electrical stimulation (NMES) in the upper limbs associated with a cycle ergometer in the lower limbs, during hemodialysis, on functional capacity and peripheral muscle strength. The hypothesis is that in people with chronic kidney disease on hemodialysis, the addition of neuromuscular electrical stimulation in the upper limbs associated with aerobic training of the lower limbs is superior to aerobic exercise alone in improving functional capacity, peripheral muscle strength, quality of life, safety intervention and patient adherence.
This is a Phase III, randomised, open-label, 2 arm, multicentre, international study assessing the efficacy and safety of Dato-DXd compared with ICC in participants with locally recurrent inoperable or metastatic TNBC who are not candidates for PD-1/PD-L1 inhibitor therapy.
This is a Phase 2/3, multiregional, two-arm, double-blind, randomized, active (standard-of-care)-controlled study of the efficacy and safety of tividenofusp alfa (DNL310), an investigational central nervous system (CNS)-penetrant enzyme-replacement therapy (ERT) for mucopolysaccharidosis type II (MPS II). Participants may also qualify to enter an open-label treatment phase with DNL310 or idursulfase based on pre-specified criteria.
The purpose of the current ZOSTER-101 long-term follow-up (LTFU) study of ZOSTER-049 (NCT02723773) study, an extension of ZOSTER-006 (NCT01165177) and ZOSTER-022 (NCT01165229) primary studies, is to assess the long-term vaccine efficacy (VE) against Herpes Zoster (HZ) (approximately 11-15 years post primary vaccination in ZOSTER-006/022 studies), persistence of immunogenicity and safety of GSK's Herpes Zoster subunit (HZ/su) vaccine in older adults. The persistence of immunogenicity and safety of 1 or 2 additional doses (0, 2-month schedule) of HZ/su vaccine administered to a small group of participants in ZOSTER-049 study (approximately 5 years after the initial vaccination in ZOSTER-006/022 studies) will also be assessed.
Our proposal is to develop a sentinel syndromic surveillance strategy to identify encephalitis cases possibly related to emerging pathogens admitted to ICUs in Brazil. "Sentinel" to allow a diagnostic intensive approach on a smaller number of cases, "syndromic" to guarantee a sensitive criterion to include new or unexpected pathogens, and in ICUs to prioritize potentially severe threats. In a resource-limited setting it won't be possible to monitor and investigate all cases of encephalitis, so a cost-effective algorithm for early identification of the cases that are most likely to be caused by unusual, unexpected or emerging pathogens must be developed. As universal surveillance of encephalitis is not recommended in Brazil, data on incidence, causes and prognosis is not available, leaving a gap in the understanding of the epidemiology of this central nervous system disease in the country. This study will review cases of encephalitis admitted in the last five years to ICUs in a large metropolitan area. Its results will help understand the epidemiology of encephalitis in Brazil and will provide data to build a strategy for early identification of outbreaks and of emerging infectious diseases.
