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.
Introduction The portable monitoring system (PMS) recording of cardiopulmonary parameters (level III of ASDA) has been validated in subjects with high probability of Obstructive Sleep Apnea (OSA) without comorbidities. However, there is not any study evaluating this system when OSA is associated with morbid obesity, so the validation of PMS will be very useful in order to properly work-up this highly risk population. Objective: To evaluate the accuracy of level III type of PMS - Stardust™" (STD), on patients with level II and III of obesity and high clinical suspicion of OSA. Methods:Participants with BMI > 35 kg/m2 and with suspicion of OSA will consecutively be selected from an Outpatients Sleep Clinic of UNIFESP. They will be randomized for the following order of recordings: 1) STD at home for 1 night 2) STD in the sleep lab simultaneous to PSG. AHI will be taken for subsequent analysis:a) AHI PSG b) AHI STD -lab and c) AHI STD- home.
The primary objective of the study is to evaluate the long-term safety of recombinant human Factor VIII Fc fusion protein (rFVIIIFc) in participants with hemophilia A. The secondary objective of the study is to evaluate the efficacy of rFVIIIFc in the prevention and treatment of bleeding episodes in participants with hemophilia A.
The purpose of this study is: - To compare blood sugar control on LY2605541 with insulin glargine after 52 weeks of treatment. - To compare the rate of nocturnal low blood sugar episodes on LY2605541 with insulin glargine during 52 weeks of treatment. - To compare the number of participants on LY2605541 reaching blood sugar targets without low blood sugar episodes at night to those taking insulin glargine after 52 weeks of treatment. - To compare the rate of low blood sugar episodes on LY2605541 with insulin glargine during 52 weeks of treatment
The main hypothesis of this study is look for a clinical and fast test to identify salt sensitivity by administration of fludrocortisone.
Adequate pharmacological treatment controls symptoms in most asthmatics. Pressurized metered dose inhalers (pMDI)are the most used drug delivery devices. Valved holding chambers of different types and sizes have also been developed for use in combination with pMDI. The therapeutic efficacy of treatment depends on the amount of inhaled particles. The chambers can optimize lung deposition as it obviates lung-hand coordination and retain larger particles. The aim of this study is to compare the efficacy of the fine particle combination pMDI Beclomethasone/Formoterol in asthma control,with or without the aid of a spacer in patients without adequate asthma control on medium to high-dose inhaled steroids associated with long acting beta adrenergic drugs. The hypothesis is that there is no clinical efficacy difference between the two forms of drug administration.
Obesity is a chronic disease now considered a major public health concern in the global context, as it causes or exacerbates many diseases limitations in providing quality of life and higher treatment costs. The increase in the number of patients undergoing bariatric surgery and the excess skin and subcutaneous tissue adjacent to slimming collaborate in the search for growth by plastic surgery. Currently several techniques of thighplasty has been submitted but no studies were found that evaluated the characteristic clinical and emotional resulting from this procedure. This study has as a goal to evaluate the body image and quality of life in women submitted to thighplasty.
The purpose of this study is to evaluate the effectiveness of a brazilian cardioprotective diet plan to reduce cardiovascular risk factors of new cardiovascular events.
Several factors characterize repetitive transcranial magnetic stimulation (rTMS) as a strategic aid in the treatment of postpartum depression. However, up to current days there have been no studies evaluating the effects of rTMS on neurocognitive and social performance of women suffering from the disorder. The present study evaluates the impacts of rTMS in clinical, cognitive and social performance.
Introduction: Patients undergoing noncardiac surgery are at increased risk of cardiovascular complications. The development of methods that can accurately predict the occurrence of these events is of critical importance and large studies have been published with this purpose. Based on these studies, several algorithms have been proposed to predict of cardiovascular events postoperatively. However, quantification of this risk is often difficult to measure, especially in those patients with subclinical disease, not always detected in routine evaluation. The ankle brachial index (ABI) has proved a valuable tool in the quantification of cardiovascular risk, and perhaps the most promising when compared with other methods. It is easy, cheap, fast and feasible in office care, with a great acceptance between patients and small intra and inter observer variability. Despite strong evidence of the utility of ABI as a tool in assessing cardiovascular risk, there are no data about the use of ABI in other patients referred for non vascular surgery, which constitutes the majority of operations performed worldwide. Objectives: To evaluate the use of ABI as a predictor of cardiovascular events in patients undergoing non-cardiac and non-vascular surgery and its applicability as a tool in the reclassification of patient risk groups established by guidelines for perioperative evaluation. Methods: 300 moderate to high risk patients referred for non-vascular and non-cardiac will be included. Data about risk factors, signs and symptoms, physical examination and treatment used will be collected before surgery. The ABI will be measured and the patient will be monitored for 30 days to the detection of cardiovascular events: death from any cardiovascular causes, unstable angina, nonfatal myocardial infarction, isolated elevation of troponin, decompensated heart failure, cardiogenic shock, stop nonfatal heart failure, pulmonary edema, stroke and lower limb ischemia. Postoperative electrocardiogram, total creatine kinase, MB fraction and troponin I will be measured daily until 3º day and whenever clinically indicated.
In the past many authors have reported the abnormal contact between the rotator cuff and coracoacromial arch, but the exact etiology was not clearly understood. Thus, the objectives of this study relate specifically to improve the symptoms and rehabilitation of shoulder function of the patient: 1. Assess the effectiveness of magnet therapy in the treatment of impingement of the rotator cuff; 2. Assess whether the application of magnetic therapy 3 times a week for three weeks, may be effective as a single treatment of impingement of the rotator cuff; 3. Assess whether the combination of magnetic therapy with therapeutic exercises is more effective than magnetic therapy only; 4. Evaluate the benefits of magnetic therapy associated with therapeutic exercise in the short and long term. 5. Assess the effectiveness of the modulation of pulsed electromagnetic field at 25 Hz and 20 mT in patients with shoulder impingement syndrome.
