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.
The purpose of this international, multicenter study is to determine ventilation practice and outcomes of intubated and ventilated intensive care unit (ICU) patients. Ventilation characteristics and outcomes will be compared between patients without the acute respiratory distress syndrome (ARDS), patients at risk for ARDS, and patients with mild, moderate or severe ARDS. Participating centres worldwide will include adult patients undergoing mechanical ventilation in the ICU during a 7-day period. Patients data will be collected during the first 7 days in the ICU, or until ICU discharge. Follow up is until day 90. Primary endpoint is the tidal volume size used during mechanical ventilation. Secondary endpoints are development of ARDS in patients without ARDS at the onset of mechanical ventilation, worsening of ARDS in patients with ARDS at the onset of mechanical ventilation, pulmonary infection, other pulmonary complications, need for tracheostomy, extra-pulmonary complications, duration of ventilation, length of ICU and hospital stay, and ICU, hospital and 90-day mortality.
DAWA is a phase 2, prospective, open-label, randomized, pilot study. The main variable to be observed in this study is intracardiac thrombus. There are no formal primary or secondary clinical efficacy or safety outcomes because it is a pilot study.
The purpose of this study is to determine whether mirtazapine is effective in the treatment of sleep disorders in Alzheimers disease.
Exercise is considered a way to benefit the health of unhealthy and healthy individuals. This is confirmed by different scientific researches, in which people who participated improve their health. The present study will be conducted to test the hypothesis that vildagliptin associated with metformin may have more impact in improving glucose variability after a sub-maximal exercise test, as compared to glibenclamide. Our general aim will be to evaluate glucose variability after the submaximal exercise test under the treatment with vildagliptin or glibenclamide. The specific aims of this study are to evaluate the oxidative stress, endothelial function, metabolic and cardiovascular responses to exercise under the treatment with vildagliptin or glibenclamide. All these responses are important in patients with Diabetes Mellitus type II. Allied to the patient's routine treatment (metformin), they will receive orally a second drug, to take in 12 weeks. The patients will be raffled to take one of the two drugs that act on glycemia, that are called vildagliptin (50 mg of this drug twice a day) and glibenclamide (5 mg once a day during the first week and later you will increase to 5 mg twice a day). The metformin drug will continue be used. Patients who meet the eligible criteria for the study will first make the test of the maximum effort, to determination of peak oxygen consumption (VO2peak) and ventilatory thresholds. Forty eight hours after this test, patients will be allowed to do the pre-drugs protocol that will be given in three consecutive days as explained below. - Day 1: Begin a 24-hour urinary collection, perform vascular doppler ultrasound to evaluate endothelial function and then the glucose sensor will be inserted subcutaneously (begin continuous glucose monitoring system - CGMS evaluation); - Day 2: End the 24-hour urinary collection, submit to the submaximal test (blood collection at baseline, 15 and 30 min of the session, and 60 min after recovery). On the same day, the patients will begin 24h ambulatory blood pressure monitoring (24h-ABPM). - Day 3: Removal of the glucose sensor; end of the 24h ABPM, randomization. This same protocol, except the randomization will be repeated at the end of the 12 week treatment.
THis study is intended to provide contemporary data on the burden of disease in patients 1 to 3 years post-MI, including a description of patient characteristics, current treatment patterns, rate of major CV events, and healthcare resource utilization in a 'real world' patient population at high atherothrombotic risk.
Since yoga breathing exercises are traditionally used to tranquilize the mind, and have a well-known positive effect on the cardiovascular system, it is our hypothesis that a respiratory yoga exercise named bhastrika pranayama may have positive effects on heart rate variability, electroencephalography, quality of life and salivary cortisol (stress hormone).
Condition: patients with breast cancer. Intervention: spiritual support (relaxation + image guided + meditation) or relaxation in three consecutive meetings (day 2, 3 and 4), three days of intervention in the same week. The first day the participants will be evaluated if she meets the needs of the research and will answer questions about their indentification and spirituality. Type of study: intervention Study design: randomized controlled trial Masking: blind study. Randomization: sequence generated by SPSS (Statistical Package for the Social Sciences) version 15, organized in sealed envelopes by another qualified professional. The research ends in 2014 jun.
The purpose of this study is to determine the effectiveness of the addition of the use of Kinesio Taping in patients with chronic nonspecific low back pain who receive conventional physical therapy.
Carbon dioxide infusion is a non surgical procedure applied via percutaneous, transdermal and subcutaneous. Increase in the concentration of carbon dioxide decreases pH activating local nitric oxide that stimulates collateral vessels formation, vascular endothelial growth factor and basic fibroblast growth factor. Carbon dioxide infusion restores the blood flow in chronic wounds of the lower limbs.
The objective of this trial is to study the effects of omega-3 PUFA supplementation on the inflammatory response and lipid profile in patients with chronic Chagas cardiomyopathy. Study Type: Interventional Study Design: A total 40 patients will be randomly assigned into two parallel groups. The intervention will be treatment with omega-3 PUFAs at a dose of 3 g/day for 8 weeks, compared to placebo (corn oil). The primary endpoints will be the concentrations of inflammatory markers (IL-1, IL-2, IL-4, IL-6, IL-10, TNF-alpha, IFN-γ, and TGF-β). Secondary endpoints will be the fasting glucose, lipid, and anthropometric profiles.
