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 study is to evaluate the pharmacokinetic (PK) properties of antiretroviral (ARV) and anti-tuberculosis (TB) drugs administered during pregnancy and postpartum.
This study evaluates if the combination of thermotherapy (one application, 50⁰C for 30") and 3 weeks of miltefosine is safe and have a comparable cure rate with the current recommended first line treatments comprising meglumine antimoniate for 3 weeks for the treatment of uncomplicated cutaneous leishmaniasis cases in the New World.
To evaluate pulmonary changes and the results of a cardiopulmonary rehabilitation protocol (CPRP) in patients after SARS-VOC-2 infection. Clinical trial type study to be conducted between 2020 and 2024 involving clinical-functional cardiopulmonary imaging and blood transcriptome profile: before CPRP (T1), 2 months after CPRP (T2) and 1 year later (T3). Expected results: a) clinical, image and transcriptome changes; b) clinical-functional improvement after CPRP.
This is a cluster randomized controlled trial (CRCT) to evaluate the efficacy of Wolbachia-infected A. aegypti mosquito releases in reducing the burden of ARBV infection in Brazil over four years. The intervention will be the release of Wolbachia-infected A. aegypti mosquitoes. Standard control measures routinely established by the Belo Horizonte City Hall as recommended by the PNCD, will continue to be performed by the Belo Horizonte Health Department (Zoonoses Management) in all clusters, that is, the standard control measures will be carried out throughout the city of Belo Horizonte, independent of this clinical study. Wolbachia-infected A. aegypti will be deployed by releasing adult mosquitoes in pre-determined, thoroughly spaced release points in easily accessible roads described in a release map. A release map will be generated for each cluster and the numbers of release points will be determined by population density, surface area and mosquito abundance. Wolbachia-infected A. aegypti mosquitoes will be deployed across intervention clusters in two stages: 1) a 4 month establishment stage in which most of the releases will occur and 2) followed by an 8 month consolidation stage in which the abundance of Wolbachia-infected mosquitoes will be measured and remedial deployments will be completed, if needed, with the aim of achieving a high prevalence of Wolbachia amongst A. aegypti mosquitoes in intervention clusters within 12 months from the start of the release. The goal is to reach a Wolbachia prevalence of 60% or higher. Monitoring of Wolbachia prevalence in the cluster will continue throughout the study period, but no further mosquito deployments will occur after the consolidation stage is complete. The primary objective is to evaluate whether release of Wolbachia-infected Aedes aegypti mosquitoes plus standard Aedes vector control measures reduces the sero-incidence of ARBV infection compared to standard Aedes vector control measures alone.
The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.
The project aims to idealize a pelvic suspension device as an auxiliary physiotherapeutic resource for patients with reduced mobility and functional capacity, which should favor autonomous and independent performance in personal, social and work tasks of the target population. This is a controlled clinical trial study. The research sample will be composed of patients of both sexes, aged 21 to 65 years, diagnosed with low back pain, referred to UEAFTO/UEPA, through the SUS care network. The research participants will be evaluated by posture, active mobility and muscle strength of the spine, evaluation of pain intensity and functional capacity. A device will be built with the function of keeping the user in position of pelvic suspension promoting lumbar traction that will consist of a structure of pvc pipes and connections and padded material. Participants will be submitted to 10 sessions of use of the device, after which they will be reevaluated through the same procedures. The information collected will be analyzed through the Graphpad prism software. To compare measured values, the Shapiro-Wilk test will be used for normality distribution. Student's t-tests will be used for the treatment of variables with normal distribution, and Fisher's and Mann-Whitney's exact tests for variables without normal distribution. It is expected to collaborate in the social integration, labor and quality of life of people affected by low back pain, as well as to promote the development of low-cost technologies in the routine of Physiotherapy and public health in the State of Pará.
Mechanical ventilation (MV) is an essential therapy for patients with acute respiratory failure. The ventilatory weaning process should be started when the precipitating causes of the use of the ventilatory prosthesis are resolved. Inappropriately slow weaning exposes the patient to unnecessary discomfort, increases the risk of complications and increases the cost of hospital treatment. In this sense, indices that can predict successful weaning are of great value.
Classical ballet is a type of high performance dance that requires great effort and extreme joint positions by its dancers, not to mention a precise control of the ankle joint when on pointe position. Ballet dancers excessively dorsiflex, and especially plantar flex the ankle, which predisposes anterior displacement of the talus, possibly causing mobility restrictions of the tibiotarsal articulation and making it difficult and painful to move the ankle while dancing. The Thrust technique of tibiotarsal joint is a manipulation that aim to improve mobility and articular function through a high-speed and short-range movement. The purpose of the study is to verify the effect of the Thrust technique of tibiotarsal joint on the pain symptomatology in classical ballet dancers. Ballerinas included in the study presented pain in the ankle when dancing classical ballet, tenderness to palpation in the anterior and posterior tibiotarsal articulation, and dysfunction after compression of the tibiotarsal articulation. The sample consisted of 20 ballerinas, out of which 10 were subjected to manipulation (IG) and 10 formed the control group (CG). Algic symptomatology in classical ballet dance was assessed after some practice with the Visual Analogue Scale (VAS). After that, an algometer was used to quantify the threshold of pain in the anterior and posterior ankle joint that presented restrictions in mobility. The Tug technique was performed in the tibiotarsal articulation in the IG, and in the CG it was simulated. The threshold of pain in the anterior and posterior tibiotalar joint was measured again immediately after the intervention or simulation. The ballerinas were reassessed using algometry and the Visual Analogue Scale (VAS) one week after the manipulation.
AL (or light chain) amyloidosis begins in the bone marrow where abnormal proteins misfold and create free light chains that cannot be broken down. These free light chains bind together to form amyloid fibrils that build up in the extracellular space of organs, affecting the kidneys, heart, liver, spleen, nervous system and digestive tract. The primary purpose of this study is to determine whether CAEL-101, a monoclonal antibody that removes AL amyloid deposits from tissues and organs, improves overall survival and it is safe and well tolerated in patients with stage IIIa AL amyloidosis.
Coronavirus Disease (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has led to unprecedented morbidity and mortality in the modern era. To date, nearly 13 million people have contracted COVID-19, leading to more than 550,000 deaths worldwide. As the number of affected individuals continues to climb, effective strategies for treatment and prevention of the disease are of paramount importance. SARS-CoV-2 is understood to directly invade cells via the human angiotensin-converting enzyme 2 (ACE2) receptor, which is expressed predominantly in the lungs but also throughout the cardiovascular system. Thus, while acute respiratory distress syndrome remains a feared complication, new thromboembolic disease has emerged as a common and potentially catastrophic manifestation of COVID-19.
