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 evaluates the safety and efficacy of lefamulin, a pleuromutilin, for the treatment of adults with moderate community-acquired bacterial pneumonia
So far, no study investigated the safety and efficacy analgesic of transcranial direct current stimulation (tDCS) associated to peripheral electrical stimulation (PES) in individuals with SCD who suffer from chronic pain. Several studies have reported a decrease in O²Hb concentration in the regions below the electrodes and in other cortical areas during anodic or cathodic tDCS, which implies a risk factor for vasoocclusive events in individuals with SDC due to polymerization of hemoglobin when exposed to these low O²Hb concentrations. For this reasion, the aim main of this study is to assess the effect of a single session of transcranial direct current stimulation (tDCS) associated to peripheral electrical stimulation (PES) on safety and efficacy analgesic in individuals with sickle cell disease (SCD). Others aims sencondaries are evaluate the effect of a single session of transcranial direct current stimulation (tDCS) associated to peripheral electrical stimulation (PES) on biomarkers neurophysiological and inflammatory.
Objective: Investigating the immediate effects of Low Level Laser Therapy (LLLT) on neuromuscular performance in healthy subjects after an induced muscle fatigue protocol. Methods: Eighty volunteers of both genders aged between 18 and 28 years underwent a preliminary evaluation using surface electromyography and isokinetic dynamometer of the flexor muscles of the elbow. The subjects were randomly allocated into 4 groups: G1 was control group; G2 placebo; G3 laser applied before fatigue protocol; and G4 immediately after. Muscular fatigue protocol consisted of 30 maximal concentric isokinetic contractions at 120°/s of the elbow flexor muscles. An 808 nm equipment was used for applying laser therapy, with a power of 100 mW and total energy of 20 J. Volunteers were reassessed after interventions.
Prospective phase II study. Patients will be submitted to neoadjuvant chemotherapy (cT) and hypo fractionated radiotherapy (hRT) following by surgery. The remain viable cells will be analyzed and the patients whithin less than 30% will receive more 3 cycles of cT. All patients have deep high grade soft tissue sarcoma of extremity.
The aim of this study is to evaluate the effect of a diabetes education program delivered to CHW in improving the metabolic control of patients with type 2 DM. The study is a randomized controlled trial conducted in a primary care unit. Eight CHW, providing care for 118 patients, are randomized in two groups to receive a one-month diabetes education program (intervention group, patients n= 62) or an education course in other health issues (control group, patients n= 56).
The study aims to demonstrate the efficacy of NIV continuously in cardiac rehabilitation programs, improvement of exercise tolerance, with consequent reflection in functional capacity and quality of life of this population.
This study evaluates the dentoskeletal effects of the expander with differential opening in orthodontic patients in the mixed dentition. Half of participants will undergo rapid maxillary expansion (RME) using the expander with differential opening, while the other half will undergo RME using the conventional Hyrax expander.
Cardiovascular diseases are important cause of death, and of these have highlighted the Coronary Artery Disease (CAD) and its various clinical manifestations. The chest pain suggestive of ischemic heart disease is frequent complaint in medical consultations and hospitalizations . Complementary tests and images exams for risk stratification as Cardiac Stress Test (ET), the Myocardial Perfusion scintigraphy of (SPECT) are established for risk stratification and assessment workup in suspected ischemic heart disease. Coronary tomography angiography (CTA) has emerged as a robust method for non-invasive assessment of CAD, showing data diagnostics that directly correlate with invasive coronary angiography. Recently, the Myocardial Perfusion by Tomography Computed (CTP) has emerged as a new technique to measure the flow limitation for coronary microcirculation. In clinical practice, the exercise testing with electrocardiogram changes compatible with myocardial ischemia can lead to other examinations for elucidation of ischemic etiology, the most usual myocardial scintigraphy. However, a SPECT without evidence of ischemia, does not explain ischemic electrocardiographic changes triggered by physical stress, although it is a good marker prognostic. A CTP is a emerging tool in the evaluation of myocardial ischemia. Recent studies point to a good accuracy of the method compared to nuclear medicine. To test this hypothesis, this study aims to evaluate whether the CTP has a better diagnostic performance in detecting of obstructive or not obstructive CAD compared to the SPECT in the population of patients with exercise stress testing compatible with myocardial ischemia, and the computed tomography angiography (CTA) as the reference method. In addition, data from the exercise test (functional capacity, hemodynamics, electrocardiogram changes) will be compared to findings of CTA and CTP.
Breast cancer is the most frequent malignancy in the female population Brazilian, except non-melanoma skin tumors. Surgery plays an important role in regional spot disease control and the definition of parameters for the adjuvant treatment indication. Surgical site infections (SSI) are defined as wound infections occur following invasive procedures, corresponding to 14-16% of all infections nosocomial in hospitalized patients, the most common among patients surgical. SSIs should be examined as potential wound contamination surgical, understood as the number of micro-organisms in the body and / or tissue being operated. Considering this aspect, the cancer surgery breast are classified by their potential for contamination by clean. The use of antibiotics to prevent the SSI in mastectomies is not standardized in Handbook of National Health Surveillance Agency due to the effectiveness of undocumented prophylaxis Thus the use of antibiotics may vary among services. So this randomized clinical trial to evaluate the influence of the use of Prophylactic antibiotics in SSI rates in oncological breast surgery.
Relapsed acute myeloblastic leukemia (AML) requires remission prior to allogeneic Hematopoietic Stem Cell Transplant (HSCT) for optimal survival, but is a disease with poor response to chemotherapy. Human leukocyte antigen (HLA) haploidentical, Natural killer (NK) enriched peripheral blood cell infusions have shown safety in patients with poor prognosis AML. Though not powered for such an assessment, this trial showed a promising but not statistically significant trend in remission rate. NK cell therapy was limited by small numbers of NK cells attainable through leukapheresis. We have now demonstrated that large numbers of NK cells can be propagated ex vivo from a small volume blood draw, obviating the need for donor leukapheresis. The purpose of this trial is to determine the feasibility and maximum tolerated dose of expanded NK cells and estimate the toxicity of treating relapsed/refractory AML with fludarabine + high-dose cytarabine + G-CSF (FLAG) chemotherapy followed by haploidentical expanded natural killer (NK) cells. The first NK cell dosing cohort will be well below the currently-established safe dose of pheresis-derived NK cells, as expanded NK cells may have increased toxicity because of their activated phenotype. In order to avoid accruing patients at suboptimal doses, a dose escalation schema based on the principles of an accelerated titration design is used in this study to allow expeditious advancement up to the current safe dose of NK cells.
