There are about 9909 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.
RGX-111-5101 is a long-term follow up study that evaluates the long term safety and efficacy of RGX-111 in participants who have received RGX-111 (a gene therapy intended to deliver a functional copy of the alpha-L-iduronidase gene (IDUA) to the central nervous system) in a separate parent study.
The aim of the study will be to evaluate shear stress and blood flow parameters in lower limb arteries during arm cycle ergometer exercise in participants with peripheral artery disease. Twenty patients participants with peripheral artery disease and claudication symptoms will be recruited. Participants will perform 3 experimental sessions in random order. Iarm-cranking (15 sets of two minutes exercise), warm water foot immersion, and control. During the interventions, blood pressure and heart rate will be assessed every 6 minutes. Measurements of arterial diameter, blood flow, anterograde and retrograde shear stress of the femoral artery will be evaluated using a two-dimensional ultrasound device with spectral Doppler.
Introduction: Positive psychological's constructs have shown a direct effect on adherence to pharmacological treatment, diet, physical activity and general commitment to health, in the same way that negative ones, such as depression, anxiety and stress, are associated with worse cardiovascular outcomes and are prevalent in patients with infarction. Objective: To verify whether a gratitude intervention can improve self-care and improve negative psychological states in patients with recent myocardial infarction. Methods: Randomized, parallel clinical trial. The inclusion criteria will be patients with ST-segment elevation myocardial infarction (STEMI) with less than 12 hours of evolution and undergoing primary percutaneous coronary intervention (pPCI). Participants will respond to the socio-demographic and risk factors questionnaire and self-care (ASA-A), anxiety, depression and stress (DASS-21) and gratitude (QG-6) scales. They will be drawn into the gratitude intervention group or neutral events group according to the randomization list. Patients in the intervention group will be tasked with writing down 3 to 5 situations a day for which they are grateful, for 14 days. Patients in the control group will be asked to write down 3 to 5 situations a day that have impacted them, whether good or bad. Both groups will be reassessed after the intervention and after 6 months. Expected results: It is expected that the intervention group will improve self-care and the feeling of gratitude, modify behaviors and decrease negative affects, while the group without intervention will remain unchanged from the beginning of the study to 6 months.
Gum disease require a lifetime supportive periodontal care aiming at preventing additional inflammation and bone resorption. During this phase it is also relevant to keep germs under acceptable levels through proper daily hygiene although patient's cooperation tends to decrease over time. There are conflicting opinions regarding combination of dental scaling with antibiotics. This is why the present study was designed to evaluate the clinical and microbiological effects of combined therapy 1 year following supportive periodontal care. Fifty patients who voluntarily decide to participate will receive dental scaling associated with two different antibiotics or placebo capsules. Paper points will be used to collect dental plaque samples and levels of bacteria will be determined. Dental specialists will also perform clinical examinations. Patients would be available for 4 dental appointments: prior to and 3, 6 and 12 months after dental scaling.
This is a randomized clinical trial in an online format, which will only include people with PD randomly divided into two groups: Group 1 - Social Telerehabilitation with Dance and Music Group 2 - Social Telerehabilitation with Multimodal Therapeutic Exercise and Music
The goal of this clinical trial is to investigate a new approach for treating large uveal melanomas, a type of eye cancer. The study aims to determine the effectiveness of using intra-arterial melphalan, a chemotherapy drug, to reduce tumor thickness, allowing for subsequent radiation therapy using a Ru-106 plaque. The main questions this trial seeks to answer are: - Can intra-arterial melphalan effectively reduce the thickness of large uveal melanomas? - Is the combination of intra-arterial melphalan and brachytherapy a safe and effective treatment option for these tumors? Participants enrolled in the trial have clinically diagnosed choroidal melanoma with tumor thickness equal to or greater than 8.00 mm. They will undergo a procedure where the chemotherapy drug is injected directly into the blood vessels that supply the tumor. After a few weeks, they will receive the radiation treatment using a small device placed on the eye. Throughout the trial, participants will have different tests to monitor the tumor and their vision, such as ultrasound scans, pictures of the inside of the eye, and a test called electroretinography (ERG) to check the function of the retina. These tests will be done at the start of the trial and at 1, 3, and 6 months later to track the progress of the treatment.
The purpose of this observational study is to measure how many people are overweight or obese amongst patients with a diagnosed cardiovascular disease (CVD). The study also aims to characterise the population including the presence of cardiovascular (CV) risk factors in a number of countries across the globe representing different geographies, ethnicities, as well as different healthcare systems.
Lung cancer is the most common type of cancer and the leading cause of cancer death worldwide, in both men and women. Improvements in earlier preoperative staging and more effective adjuvant treatment have improved survival in non-small cell lung cancer, although surgical resection remains the mainstay of care for all patients in stages I to IV. This study proposes to evaluate the functional capacity through TGlittre in patients with non-small cell lung cancer, before and after thoracic surgery, taking into account the predictive role of this test in the risk of complications and in the evaluation of the impact of functional rehabilitation.
Hypertension and diabetes mellitus (DM) are highly prevalent in low and middle-income countries, and the proportion of patients with uncontrolled diseases is higher than in high income countries. Innovative strategies are required to surpass barriers of low sources, distance, and quality of healthcare. Our aim is to assess the uptake and effectiveness of the implementation of an integrated multidimensional strategy in the primary care setting, for the management of patients with hypertension and diabetes mellitus (DM) in Brazil. This is a scale up implementation study that has mixed-methods, and comprehends four steps: (1) needs assessment, including a standardized structured questionnaire and focus groups with healthcare practitioners; (2) baseline period, three months before the implementation of the intervention; (3) cluster randomized controlled trial (RCT) with a 12-month follow-up period; and (4) a qualitative study after the end of follow-up. The cluster RCT will randomize 35 centres to intervention (n= 18) or usual care (n= 17). Patients ≥18 years-old, with diagnosis of hypertension and/or DM, of five Brazilian cities in a resource-constrained area will be enrolled. The intervention consists of a multifaceted strategy, with a multidisciplinary approach, including telehealth tools (decision support systems, short message service, telediagnosis), continued education with an approach to issues related to the care of people with hypertension and diabetes in primary care, including pharmacological and non-pharmacological treatment and behavioural change. The project has actions focused on professionals and patients.
The main objective of this type 2 hybrid implementation effectiveness trial is to implement a contextually appropriate preventive intervention for 12 weeks face to face group foot and ankle exercises for people with diabetic foot in the primary care of the city of Limeira/SP, through the training of Primary Care workers. The study will monitor the implementation itself and the clinical outcomes: clinical and functional status and quality of life.
