There are about 8753 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.
Considering the auxiliary potential effect of photobiomodulation in controlling persistent CTT and TMD-related pain in patients who have been diagnosed with COVID-19, and are recovered from the viral infection, we intend to conduct a clinical trial comparing two modalities of therapeutic laser application: local application and transcutaneous application in the radial artery. One of the main advantages of auxiliary techniques in pain control is the decrease of the use of drugs for analgesia, avoiding side effects and tolerance caused by them, and promoting an improvement in the individual's quality of life.
Soft tissue sarcomas are rare malignant tumors. Liposarcoma constitute the most frequent histological subtype of retroperitoneal sarcoma. The prognosis of soft tissue sarcomas depend on clinical and histologic characteristics. Objective: Evaluate variables that may be related to overall survival and local recurrence free survival in patients with retroperitoneal liposarcoma. Methods: retrospective analysis of medical records of 60 patients attended from 1997 to 2017, who underwent surgical resection of retroperitoneal liposarcoma.
Cervical pain contributes to postural deviations and imbalance. Nanotechnology may be used for the treatment of neck pain by fixing to the skin small rounds silicone patches containing double spiral carbon nanotubes arranged in the form of a coil (Helical), which would then relieve dizziness caused by muscular contraction.
Collection of clinical and genetic data to help identify individuals that carry genetic variants of known importance in Non-alcoholic Steatohepatitis (NASH)
The proposed study is a bidirectional analytical study, composed of a retrospective and a prospective cohorts. Patients with stage II - III colorectal cancer undergoing oncological surgery will be analyzed. The study will include a convenience sample of 100 individuals. Fifty cases will be included retrospectively and fifty prospectively. The study aims to evaluate the benefit of using the Immunoscore test as a predictor of recurrence in patients with operated stage II-III colon tumors. It will also be evaluated the impact on oncologic decision and costs.
Introduction: Patients on mechanical ventilation suffer alterations in the viscoelastic characteristics of the mucus due to changes in the humidity and temperature of the inhaled air and in the respiratory volumes and flows. The literature has pointed out the use of mechanical ventilators as a tool for mobilizing secretions and closed-system aspiration associated with expiratory pause has been shown to be effective in mobilizing secretions. Objectives: To assess whether there is a difference in the mass of aspirated secretion with the application of the expiratory pause during aspiration. Methods: A crossover, randomized study. Applied to children aged 0 to 5 years and 11 months who are intubated for 24 hours with orotracheal tubes or tracheostomy. There will be an exclusion of patients who present with undrained pneumothorax, cranial hypertension or any other clinical situation that has a clinical contraindication to aspiration and patients whose parents do not agree to participate in the study. The technique will be during aspiration in the tube with where to apply or not the expiratory pause on the mechanical ventilator. This secretion will be weighed so that there is fidelity in the results.
The purpose of this study is to evaluate the effect of probiotic supplementation on fecal microbiota, nutritional status, metabolic and inflammatory parameters in patients with type 2 diabetes mellitus. Study hypothesis: Supplementation of multispecies probiotic (Bifidobacterium Lactis, B. brebe, B. longum, Lactobacillus gasseri, L. casei, L. rhamnosus) during 12 weeks improves the the fecal microbiota composition and promotes reduction of plasma/serum levels of acute phase proteins, cytokines, metabolic and anthropometric parameters in individuals with type 2 diabetes mellitus.
Sotalol is an antiarrhythmic medication with proven effects for the suppression and prevention of supraventricular and ventricular arrhythmias. Due to its potential proarrhythmic effect, its introduction should be cautious, and several guidelines recommend starting the medication in hospital settings. However, patients at low risk for a proarrhythmic effect start the medication in outpatient units, despite the lack of clinical studies in the literature that demonstrate the safety of introducing the medication outside the hospital environment. This research project aims to assess the safety introduction of sotalol in an outpatient unit basis. Our hypothesis is that outpatient introduction of sotalol is safe for low-risk patients and an electrocardiographic analysis after 2 hours of the first dose of medication is a predictor of electrocardiographic changes found after 72 hours. In this research, serial electrocardiographic analysis with measurements of the QT corrected intervals and its dispersion, as well as clinical and laboratory parameters will be performed in 110 patients.
Background: Non-invasive ventilation (NIV) reduces respiratory load and demands on peripheral muscles. Methods: This study aims to evaluate the acute effects of bi-level NIV on peripheral muscle function during isokinetic exercise and aerobic performance in chronic obstructive pulmonary disease (COPD) patients. This is a pilot crossover study performed with a non-probabilistic sample of 14 moderate to very severe COPD patients. Procedures carried out in two days. Dyspnea, quality of life, lung function, respiratory muscle strength, functional capacity (6-minute walk test - 6MWT), and isokinetic assessment of the quadriceps were assessed. Blood samples (lactate, lactate dehydrogenase, and creatine kinase concentration) were also collected. Right after, NIV was performed for 30 minutes (bi-level or placebo, according to randomization) followed by new blood sample collection, 6MWT, and isokinetic dynamometer tests. Before and after evaluations, the subjective perception of dyspnea and fatigue in the lower limbs was quantified. After a wash-out period of seven days, participants returned, and all assessments were performed again.
