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.
Atherosclerotic disease is responsible for one third of all deaths annually and is a major cause of comorbidities. While atherosclerosis is by itself a benign disease, it often leads to complications such as acute myocardial infarction with ST-segment elevation. Rescue angioplasty is indicated if thrombolytic therapy fails. However, the benefits in reducing mortality and the amount of myocardium effectively saved are not well established. The development of new tools, including cardiac magnetic resonance imaging to identify myocardial area at risk and infarcted increased diagnostic accuracy. However, unlike the context of primary angioplasty, little is known about the relation between coronary epicardial and microvascular flow after rescue angioplasty and myocardial salvage. The objective of this study is to evaluate whether there is a relation between these flows and myocardial salvage identified by Magnetic Resonance Imaging (MRI). At the end of this research, the investigators hope to contribute to a better understanding of coronary flow and its relation to the amount of heart muscle saved after rescue angioplasty. This is an important information that can help understand which cases benefit most from rescue angioplasty.
This is a prospective, intervention, randomized, phase IV study. Patients will be included with 60 years or older, both sexes, with HbA1c >8.5% using oral antidiabetics agents and insulin and then we will be randomized by use syringe or pens device to use insulin NPH and regular. All patients will receive a blood glucose monitor, lancet tapes, capillary blood glucose tests (3 tests/day). HbA1c will be measured at baseline, 3 and 6 months. Patients will see monthly.
Due to the lack of information in the literature about the role of cardiac rehabilitation on Chagas heart failure, the aim of the present study was to evaluate the effects of a cardiac exercise program on functional capacity, cardiac function, respiratory muscle strength, body composition, biomarkers and quality of life among Chagas heart failure patients.
The purpose of this study is to assess platelet aggregability by a "point of care" device (Multiplate®) to decrease the release time for coronary artery bypass graft (CABG ) in patients with acute coronary syndrome (ACS) in use of dual antiplatelet therapy.
A Phase III, Randomized, Open-Label, Controlled, Multi-Center, Global Study of First-Line MEDI4736 (Durvalumab) Monotherapy and MEDI4736 (Durvalumab) in Combination with Tremelimumab Versus Standard of Care Chemotherapy in Patients with Stage IV Urothelial Cancer
During normal breathing, the upper and lower airways performs the priming of inspired gas: humidification, heating and filtering from nose to the bronchios for adequate gas exchange occurs in the lungs. Many patients with severe or advanced cardiopulmonary conditions (cystic fibrosis, chronic obstructive pulmonary disease, pulmonary hypertension, advanced heart failure among others) may develop chronic respiratory failure and require treatment with oxygen therapy. High fractions of inspired oxygen have been associated with deleterious effects on the nasal ciliary beating and nose mucociliary transport. At home assistance, the patient with chronic respiratory receives oxygen via nasal cannula to the patient has been applied with and without humidification, however, does not know the effects of these two types of dry and humidified administration on the mucosa of the nose, airways and lungs. The investigators will assess the subject in use of home oxygen therapy at baseline, 12 hours, 7 days 30 days, 12 months and 24 months.
This study evaluates the effects of different volumes of aerobic exercise training in cardiovascular parameters of patients with cardiovascular diseases enrolled in a cardiac rehabilitation program.
Background: Association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been widely studied and the aspiration of periodontal pathogens is one of the most accepted causal mechanisms for pulmonary exacerbation. Bronchiectasis is clinically quite similar with COPD, including chronic administration of antibiotics, increased systemic inflammation and relatively similar clinical symptoms, but for the time being; there are no studies that have correlated this condition to PD. This study will evaluate if the scaling and root planning (SRP) associated with photodynamic therapy improves periodontal clinical parameters, halitosis, and the quantity of microorganisms associated with exacerbation of bronchiectasis in saliva, subgingival periodontal microenvironment, sputum and nasal lavage at baseline, after 3 months and one year of SRP. Methods/Design: Ninety patients with chronic periodontal disease and bronchiectasis will be enrolled in the study and they will be treated as follow:G1 control (n = 30) - supragingival scaling (SS) and dental hygiene orientation (DHO); G2 experimental (n = 30) - SRP + DHO; G3- experimental (n = 30) - SRP + PDT + DHO. The quantification of bacterial groups commonly associated with exacerbation of bronchiectasis (P aeruginosa, S. aureus) and periodontal diseases (P. gingivalis), will be evaluated in periodontal pockets, saliva, nasal lavage and sputum by quantitative PCR at baseline 3 months and one year after the SRP. G1 patients will receive SRP upon completion of the investigation. If the mean depth of probing of this group worsen (> 1mm) at 3 months they will be excluded from the study, treated (SRP) and the data will be described. Discussion: The results of this protocol will determine the efficacy of periodontal treatment in decreasing the total amount microorganisms in saliva periodontal pocket, sputum and nasal lavage, the most probable niches of bronchiectasis exacerbation, and reducing local inflammation and halitosis after 3 months and one year. It is expected an higher improvement in all parameters measured over 3 months and 1 year for G3
The FANTOM I pilot study is intended to assess safety of the Fantom Bioresorbable Coronary Scaffold in native coronary arteries.
The control of biofilm around implants is critical to the success of the implant rehabilitation of edentulous jaw with overdentures, and it is the dentist's duty to inform and guide patients, and keep their maintenance in order to prevent pathological processes that can lead to the implanted component loss.The aim of the present retrospective longitudinal study was to evaluate through clinical periodontal parameters and radiographic images in dental implants rehabilitated with overdentures installed seven years ago. individuals who underwent the installation of dental implants for making full implant-supported upper and lower mucus dentures in the Department of Implant Dentistry, Faculty of Dentistry, University of Santo Amaro, São Paulo, Brazil, in 2007. The periodontal parameters such as probing depth, plaque index, bleeding index and mobility as well as radiographic examination, are key to determine the correct diagnosis in dental implants. The control of biofilm around the implants seems to be a decisive factor for maintaining tissue health. We believe that the maintenance appointments are fundamental, but more studies should be conducted to elucidate microbial and immunological factors in implants placed and due for some time.
