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 is an observational study, meaning that no interventions is tested, to determine incidence of SARS-CoV-2 infection and COVID-19 in different clinical sites in Brazil in several age groups. The study aims to assess baseline number of infected participants and perform a follow-up along two years to determine the new cases occurring among participants during the period. All participants will collect blood samples to get more details on the immune response.
Interferon lambda is one of the main arms of the innate antiviral immune response and is critical for controlling respiratory viral infections in mice. Interferon lambda has a better side effect profile than other interferons because of the limited tissue distribution of its receptor. Peginterferon lambda is a long-acting form that has been studied extensively in human trials in viral hepatitis, confirming its safety. We propose to evaluate peginterferon-lambda in ambulatory and hospitalized patients with mild to moderate COVID-19.
The objective of this randomized controlled study will be to evaluate the dental and skeletal effects of maxillary protraction with a facemask, associated with MARPE and Class III elastics in patients with unilateral cleft lip and palate (CLP) with maxillary retrusion, compared to HYRAX type maxillary expanders. The investigators will examine differences in treatment times, along with skeletal, dental and soft tissue changes.
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a significant threat to global health. As the disease progresses, a series of acute complications tend to develop in multiple organs. Beyond the supportive care, no specific treatment has been established for COVID-19. The effectiveness, both short-term and long-term, of some promising antivirals, such as the hydroxychloroquine combination with azithromycin, needs to be evaluated. This study aims to investigate the predictive role of cardiac biomarkers and pulmonary symptoms for late complications of COVID-19 coronavirus infection on the heart and lung in patients treated with the hydroxychloroquine / azithromycin combination therapy. Thus, COVID-19 coronavirus patients undergoing hydroxychloroquine / azithromycin combination therapy will be compared to patients not undergoing this therapy. The comparison will be made by the analysis of the relationships between (1) levels of ultrasensitive cardiac troponins collected at the beginning of the infection and cardiac magnetic resonance data in the 3rd and 12th months of troponin collection and (2) findings CT scans and the results of the ergospirometers tests performed in those same periods. It is expected to demonstrate that: (1) cardiac troponin and lung tomographic findings can predict late complications of COVID-19 coronavirus infection in the heart and lung, assessed by cardiac magnetic resonance and ergospirometers one year after the beginning of the infection, and (2) hydroxychloroquine / azithromycin combined therapy can abolish the onset of these complications late. Furthermore, the results may point to the need for more rigorous monitoring of cardiologists and pulmonologists of these patients, due to the risk of hemodynamic complications, arrhythmogenic and respiratory.
The Xbox Kinect seems to be a good alternative for the older adults to perform physical activities at times that are typically associated with sedentary behaviors. The Xbox Kinect active video game has been used in various parts of the world as entertainment. The study of metabolic, cardiovascular and psychological responses during these activities may bring relevant information regarding the intensity of the exercises and, consequently, about the possibility of using these games to maintain and / or improve the cardiorespiratory fitness of the older adults. In addition, the present study may clarify the responses of activities on Xbox Kinect in elderly people with anxiety and depression symptoms. Will be selected 100 older adults. All volunteers will initially perform assessments of resting metabolic rate, cardiorespiratory fitness, functional tests, as well as subjective assessments of physical activity level, anxiety and mood. Subsequently, they will perform activities with body movements on the Xbox Kinect, which will be compared with sedentary behavior activity (TV / Movie). All activities will be monitored by means of a gas analyzer, which will record information about the behavior of energy expenditure, resting heart rate and activity. In addition, assessments of perception of effort and fun during activities will be made through subjective scales. The effects of Xbox Kinect activity on anxiety symptoms and mood will also be assessed.
The on-going Wuhan coronavirus (COVID-19) outbreak has become the world's leading health headline and is causing major panic and public concerns. On January 30, 2020, the World Health Organization (WHO) declared that the new coronavirus outbreak as a Public Health Emergency of International Concern; and March 11, 2020, characterized COVID-19 as a pandemic. On March, 13, Europe become epicenter of the pandemic all countries in South America had been infected with at least one case. Health authorities, including WHO, have issued safety recommendations for taking simple precautions to reduce exposure to and transmission of the virus. Home stay is a fundamental safety step that can limit infections from spreading widely. Unfortunately, the mandated directives against travelling and participating in outdoor activities will inevitably disrupt the routine daily activities of tens of millions of people. Prolonged home stays may lead to widespread fear and panic, anxiety and depression, which in turn can lead to a sedentary lifestyle. Thus, while quarantine is a safe and priority measure, may have unintended negative consequences. These efforts to avoid human-to-human transmission of the virus may lead to spend excessive amounts of time sitting, reclining or lying down for screening activities (games, television, mobile devices); reducing energy expenditure that, consequently, lead to an increased in a range of chronic health conditions. Therefore, there is a strong health rationale for continuing physical activity in the home to stay healthy and prevent a wide range of psychological problems on people during outbreaks of infection. However, currently, there is no sufficient information on the psychological impact and mental health of the general public during the peak of the COVID-19 epidemic and a timely understanding of mental health status is urgently needed for society. To our knowledge, there are no research examining the psychological and social impact on COVID-19 on the general population. The aim of this research is to determinate the psychological responses in general population in order to understand the anxiety, depression and stress level during Coronavirus Disease (COVID-19) confinement period, and how the level of physical activity development during this exceptional period could be influence.
The aim of this study is to evaluate the efficacy and safety of MTX-loaded nanoparticles in three different doses to treat severe COVID-19 patients.
This is a Phase III, randomised, controlled, 3-arm, multi-centre study of neoadjuvant osimertinib as monotherapy or in combination with chemotherapy, versus SoC chemotherapy alone, for the treatment of patients with resectable EGFRm Non-Small Cell Lung Cancer
The primary objective of this study is to assess whether the use of lenzilumab in addition to current standard of care can alleviate the immune-mediated cytokine release syndrome (CRS) and improve ventilator-free survival in hospitalized subjects with severe or critical COVID-19 pneumonia.
Patients with COPD are often unable to sustain a sufficient workload during exercise. The use of external strategies to improve exercise tolerance, such as non-invasive ventilation (NIV) and high-flow nasal therapy (HFNT) have been used. The objective was to evaluate and compare the acute effects of HFNT and NIV during exercise on cardiorespiratory parameters, dyspnea, exercise tolerance and comfort in patients with moderate to severe COPD.
