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.
This study aims to evaluate post-exercise recovery in healthy young men submitted to a prolonged exercise protocol of submaximal intensity with or without water intake, from the integrated analysis of autonomic (heart rate variability indices), cardiovascular outcomes (systolic blood pressure, diastolic blood pressure and heart rate) and respiratory (oxygen saturation and respiratory frequency). In addition, it will also be evaluated whether the proposed model is able to estimate the number of individuals undergoing hydration that have better recovery.
Background and aims: Patients with severe Coronavirus Disease 2019 (COVID-19) are prone to secondary bacterial pneumonia. The use of probiotics against oral pathogens might prevent lung colonization and progression to bacterial pneumonia. This study aimed to assess the effect of Streptococcus salivarius K12 combined with Lactobacillus brevis CD2 in preventing secondary bacterial pneumonia in patients with severe COVID-19. Methods: This randomized placebo-controlled phase 2 trial involved 70 patients with severe COVID-19 admitted to the intensive care unit (ICU). Patients were randomly assigned to a 7-day course of oral gel containing Streptococcus salivarius K12 2 billion colony-forming units (CFU) and Lactobacillus brevis CD2 4 billion CFU every 8 hours or placebo, starting in the first ICU day. The primary outcome was bacterial pneumonia, established according to clinical, laboratory, radiological, and microbiological findings, whereas secondary outcomes were ICU stay in days and hospital mortality.
The objective of the study is to describe the current epidemiology, treatment patterns, outcomes and healthcare resource use of adult patients diagnosed with relapsed/refractory (R/R) B-cell ALL and de novo AML in 4 Latin American countries.
This is a single-arm, open-label study to assess the pharmacokinetics, pharmacodynamics, safety, and exploratory efficacy of tocilizumab (TCZ) for the treatment of pediatric patients from birth to less than 18 years old hospitalized with COVID-19 and who are receiving systemic corticosteroids and require supplemental oxygen or mechanical ventilation.
Osteoarthritis represents failed repair of joint damage resulting from stresses initiated by any joint or periarticular tissue abnormality. The rate of progression varies among persons and within a knee over time. The symptoms and signs of knee osteoarthritis include pain, stiffness, reduced joint motion, and muscle weakness. Long-term consequences can include reduced physical activity, deconditioning, impaired sleep, fatigue, depression, and disability.This reduction in activity to avoid pain (kinesiophobia) to evade the onset of pain, especially in the acute phase, limiting their compliance with effective rehabilitation strategies such as regular exercises. Physical medicine has a wide range of analgesic anti-inflammatory and muscle stimulating treatment methods. Both diadynamic and TENS currents have become the most frequently implemented electrotherapeutic methods. The impact of diadynamic currents consists of analgesic effects and specific dynamics during the formation of physiological processes in tissues. They occur during the administration of the current and lasts up to a few hours after the treatment has been terminated. One of the theories explaining the analgesic effect of diadynamic currents is the gate control theory of pain by Wall and Melzack. Recently, another theory has become very popular. It explains the analgesic effect provoked by bodies characterized as polypeptides called endorphins. Electric stimulation using diadynamic currents generates an increase in the amount of endorphins in a system. Although the analgesic impact of TENS therapy is well known, Diadynamic currents therapies have not been studied in knee osteoarthritis pain conditions. Therefore, the aim of the present study was to investigate the medium-term effects of Diadynamic currents combined with exercise on pain and disability in patients with osteoarthritis of the knee.
Light and ultrasound can be interesting alternatives to reduce abdominal fat. Thus, the main objective of this study will be to evaluate the effects of these isolated techniques and their association in subcutaneous abdominal localized fat. These techniques will be used adding muscle electrostimulation in all groups. A total of 40 female participants will be recruited at the university outpatient, which will be distributed among four experimental groups: light + sham ultrasound + electrostimulation; light sham + ultrasound + electrostimulation; combined treatment (light + ultrasound) + electrostimulation; sham combined treatment + electrostimulation. The treatments will consist of eight sessions, twice a week for a month, being 90 minutes per session.
The main aims of the study are to learn about the percentage of mucopolysaccharidosis type II (MPS II) in adults in Brazil as well as about the diagnosis process. No study medicines will be provided to participants in this study. The data available for participants diagnosed with MPS II in DATASUS (a database of the Informatics Department of Brazilian Health System) will be reviewed. No clinic visits will be required as part of participation in this study.
Rehabilitation for work-related musculoskeletal disorders involves physical, behavioral, psychological treatment and counseling on how to deal with pain and disability. The study aims to evaluate the profile and indicators on the perception of health, pain intensity, and work ability (WA) of disability with work-related chronic musculoskeletal disease, assisted in a multidisciplinary program of worker health care.
Among the strategies that can improve the body's ability to counteract oxidative stress, the use of nutritional antioxidants has been investigated. Taurine is a "semi-essential" amino acid, also called a nitrogen compound, which has been used as an effective antioxidant due to its ability to neutralize hypochlorous acid, an extremely toxic oxidant produced by leukocytes in the inflammatory process in humans.
Digital single-operator cholangioscopy (DSOC) findings achieve high diagnostic accuracy for neoplastic bile duct lesions. To date, there is not a universally accepted DSOC classification. Endoscopists' Intra and interobserver agreements vary widely. Cholangiocarcinoma (CCA) assessment through artificial intelligence (AI) tools is almost exclusively for intrahepatic CCA (iCCA). Therefore, more AI tools are necessary for assessing extrahepatic neoplastic bile duct lesions. In Ecuador, the investigators have recently proposed an AI model to classify bile duct lesions during real-time DSOC, which accurately detected malignancy patterns. This research pursues a clinical validation of our AI model for distinguishing between neoplastic and non-neoplastic bile duct lesions, compared with high DSOC experienced endoscopists.
