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.
A placebo-controlled, randomized, double-blind, parallel group, phase III multicenter study in subjects recently hospitalized for ACS and with the appropriate genetic profile. Subjects will provide informed consent before any study-specific procedures are performed. Subject enrollment may begin in the hospital and will continue following release from the hospital. Screening procedures may be performed at the time of the index ACS event or anytime thereafter, with the condition that randomization must occur within the mandated window (4-12 weeks after the index event). Subjects will be assessed based on their medical history. Those who are likely to qualify will undergo Genotype Assay testing to evaluate genetic determination for the presence of AA genotype.
Countless studies are performed to quantify the severity of heart disease and its influence on the respiratory system, checking that their heart conditions and the surgical process determine pulmonary complications, one of the most common causes of morbidity and mortality in the postoperative period of cardiac surgery . After surgical procedures, there is a reduction of the residual volume (RV), total lung capacity (TLC), vital capacity (VC) and functional residual capacity (FRC), leading to the formation of atelectasis, with alterations in the ventilation-perfusion ( V / Q), the partial pressure of carbon dioxide in arterial blood (PaCO2) and partial pressure of oxygen in arterial blood (PaO 2). Pulmonary function is impaired in the postoperative period of cardiac surgery, due to various factors common to this major surgery that will drive the patient to develop respiratory complications such as atelectasis and pneumonia. Physical therapy plays an important role in the treatment of patients undergoing cardiac surgery, both in the preoperative period and postoperative, in order to prevent or minimize the respiratory complications. Follow-up studies on cardiac rehabilitation quantify the quality of all the activities necessary to ensure to patients with heart disease patients the best physical , mental and social conditions so that consequently they are able , with its effort to regain a normal position in the community and lead a active and productive life over time, therefore, the clinical changes resulting from an extensive cardiac surgery are already highly dedicated described in literature but which daily life factors or rehabilitation interventions that the patient will take in the late postoperative period that really assisted in his complete recovery and inclusion into society they are still not well elucidated , so it is appropriate to carry out this project due to the fact exposed to up. The project to be developed whose main justification clarify issues related to the return or preservation of the individual feature that undergoes extensive cardiac procedure , as well as incidence of mortality after 12 months of the procedure. The current literature does not expressed clearly, possible impacts on functionality and return the daily activities of the individual in the late postoperative period , since such malfunctions in the immediate post operative period are already fully understood.
Hypersensitivity pneumonitis (HP) is a syndrome with variable clinical presentation in which lung inflammation is caused by inhalation of specific organic antigens or low molecular weight particles in previously sensitized individuals. Systemic symptoms may or may not be present. Chronic HP represents the final stage of the disease, caused by prolonged exposure to a particular antigen, leading to pulmonary fibrosis. In chronic HP, pulmonary function tests (PFTs) commonly present a restrictive ventilatory pattern, with decreased diffusion of carbon monoxide (DLCO). Some patients can also have obstructive disorders with expiratory flow limitation, due to obstruction of the small airways typically caused by bronchiolar involvement in this pathology. However, PFTs are relatively insensitive for detecting small airway involvement when there is concomitant interstitial fibrosis. First, conventional PFTs may be normal in patients with small airway involvement, since they contribute to less than 30% of the total airway resistance. In addition, damage to the small airways in HP is generally occurring parallel to areas of focal fibrosis - even when small airways are involved, these regions can be completely ignored, since they are excluded from ventilation. In summary, traditional PFTs are not sufficiently sensitive to detect diffuse small airway involvement in these diseases. In these cases, other functional tests, such as forced oscillation technique (FOT) and high resolution computer tomography (HRCT) scans of the chest with expired studies, could be used for this purpose. This will be a cross-sectional study, which will include the following evaluations in 28 patients with HP recruited from our clinic: - Clinical variables: (A) demographic and anthropometric data; (B) Clinical data: Onset of symptoms and time of diagnosis C) Dyspnea score: D) Smoking: * Current or former smoker * Smoking history (number of cigarettes smoked per day and for how long); - Spirometry with forced and slow maneuvers before and after bronchodilator (salbutamol); - Plethysmography to measure lung volumes; - Diffusion capacity of carbon monoxide (DLCO); - High-resolution chest CT with expiratory scans; - Six-minute walk test; - Cardio-respiratory test using a maximal incremental treadmill. - Forced oscillation technique (FOT).
This study aims to verify whether the moisture of 400 µg of misoprostol pre uterine evacuation increases the dilatation of uterine cervix compared to dry misoprostol
People infected with HIV often have cognitive dysfunction even if they are on antiretroviral therapy (ART) and have undetectable viral loads. The study evaluated if the addition of maraviroc (MVC) and dolutegravir (DTG) (which are two antiretroviral [ARV] medications) to participants' existing ART regimens improved participants' neurocognitive performance.
The optimal levels of mean arterial pressure that must be achieved in septic shock are subject of debate. Studies tried to correlate blood pressure increase in patients with septic shock with microcirculation. However, there are few studies that specifically assessed septic shock patients with previous arterial hypertension. The main objective of this study is to evaluate the effect of increased blood pressure level in the microcirculation of these patients and compare them with patients without arterial hypertension.
Atopic dermatitis (AD) is an immune disorder, characterized by chronic skin inflammation or relapsing, whose prevalence is increasing worldwide. Its exact etiology remains unknown. The hypothesis that an appropriate early stimulation of the intestinal flora contributes to the establishment of the immune system balance has led to the use of probiotics in the prevention and treatment of AD in several clinical and experimental studies. Therefore, the objectives of this study will evaluate the clinical efficacy of the mixture of probiotics (Lactobacillus and Bifidobacterium) in children with AD through the SCORAD (scoring atopic dermatitis) and to evaluate the effects of this medication in the following laboratory parameters: skin prick test, total serum immunoglobulin E (IgE), inflammation composite (interferon gamma [ɣ - IFN], interleukins [IL1-β, IL-4, IL-6, IL-8] and tumor necrosis factor alpha) and immune tolerance composite (IL-10, IL-17 and transforming growth factor beta [TGF - β]).
The aerosol associated with noninvasive ventilation (NIV) and high flow therapy with nasal interface have been employed in an attempt to relieve respiratory distress and optimize the deposition of drugs by inhalation. Some studies report the effects of NIV association with fogging in healthy subjects, asthmatics and COPD 7.8, but studies evaluating the association between high flow nasal mist interface and therapy are scarce and most are found in vitro and animal models. The objective of this study is to evaluate the deposition of the aerosol scintigraphy using the high flow nasal interface system with vibrating mesh nebulizers using in healthy adults.
The aim of this investigation is to evaluate the impact of exercise in a cardiac rehabilitation program on functional capacity, clinical markers, quality of life and biomarkers in patients with chronic chagasic cardiomyopathy.
Chronic nonspecific low back pain is an important health condition with a high prevalence worldwide and it is associated with enormous direct and indirect costs to the society. Clinical practice guidelines show that many interventions are available to treat patients with chronic low back pain, but the vast majority of these interventions have a modest effect in reducing pain and disability. A biomechanical approach that has been raised is that a weakness of the hip abductors, extensors, and lateral rotators musculature (posterolateral complex - PLC) would lead to excessive contralateral pelvic drop during weight-bearing activities such as walking, running, climbing up or downstairs, generating an overload in the lumbar area. Although the strengthening of the hip PLC is largely used in clinical practice for treating patients with hip and knee injuries, there is still a lack of evidence regarding patients with low back pain. Therefore, questions remain about the efficacy of the hip dynamic stabilization as an additional intervention to conventional treatment in a well design trial with statistic power.
