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.
Combined spinal-epidural (CSE) for labor analgesia has been associated with fetal bradycardia and uterine hypertonia, possibly due to asymmetric decrease in catecholamine levels, when compared with epidural analgesia (EP).
Pulmonary Langerhans Histiocytosis Cells (PLCH) is characterized by infiltration of Langerhans cells and formation of loose granulomas with lymphocytic infiltrate and formation of nodular and cystic lesions on chest CT, and is often associated with smoking. Functionally, there may be obstructive and / or restrictive defect, with reduced carbon monoxide diffusing capacity. Dyspnea and lower exercise tolerance are common in PLCH, but exercise capacity in this disease is poorly understood and has not been compared to controls. Besides, the mechanisms involved in limiting exercise are poorly understood and cover multiple factors such as change in gas exchange, pulmonary hypertension (PH), dynamic hyperinflation, physical deconditioning and left heart failure. The involvement of pulmonary circulation in PLCH has unknown prevalence, but contributes to the symptoms. In the PH classification, PLCH belongs to the group 5, of multifactorial etiology. The definition of the presence and contribution of dyspnea mechanisms in different severities of PLCH is important to understanding the disease and individualization of treatment. The objective of the study is to evaluate the exercise capacity of patients with HCLP, and determinate mechanisms of dyspnea and lower exercise tolerance beyond its impact on quality of life.
The main aim of the study is to investigate the pre-emptive effect of dexamethasone and diclofenac associated to codeine to prevent the pain, edema and limited mouth opening at the extraction of third molar.
To evaluate the diagnostic accuracy of the 18Fluor-fluorodeoxyglucose ([18F]FDG) in the Positron Emission Tomography/Computed Tomography (PET/CT) as compared to mediastinoscopy for staging of non-small cel lung carcinoma.
To evaluate and improve the safety and efficacy of hypothermia as an adjunctive therapy to percutaneous coronary intervention in patients with acute myocardial infarction.
The principal goal of this study is to describe the epidemiology of breast cancer in the Brazilian population
MeRes-1 Extend study is designed as prospective, multinational, multicentre, single arm, open label, pilot study to assess the safety and performance of the MeRes100 Sirolimus Eluting Bioresorbable Vascular Scaffold System (BRS) in subjects with de novo native coronary artery lesions. 64 subjects will be enrolled from the 8 centers located in Asia Pacific, Europe, Brazil and South Africa. Primary outcome of study will be Proportion of population reporting Major Adverse Cardiac Events at 6 months from the day of index Procedure.
The purpose of this study is to describe demographics and socioeconomics characteristics associated to the diagnosis of metastatic breast cancer in Brazil.
The primary objective of this study was to evaluate the effect of 12 weeks of subcutaneous evolocumab (AMG 145) in combination with statin therapy (atorvastatin) on percent change from baseline in low-density lipoprotein cholesterol (LDL-C) in diabetic adults with hyperlipidemia or mixed dyslipidemia.
Before the start of the selected chemotherapy patients will be treated preventively for oral mucositis. A group will carry out the mouthwash with chlorhexidine 0.12% twice a day for five days and another will be held to damage preventive therapy (wavelength of 660nm, power 100mW and lluencia of 4 J / cm² per point, with distance of 2cm between points located on the right buccal mucosa, left buccal mucosa, hard palate, upper lip and lower lip). Patients who develop oral mucositis even after the prevention, will be divided into three groups for laser sessions with the purpose of treatment of oral mucositis. The group assignment obeyed severity of oral mucositis. Group 1 will include patients with oral mucositis grade 1. Sera used wavelength of 660nm, power 100mW and lluencia of 4 J / cm². Group 2 included patients with oral mucositis grade 2. Sera used with a wavelength of 660nm, power 100mW and lluencia of 8 J / cm². Group 3 included patients with oral mucositis grade 3 Sera used laser diode AsGaAl operating in continuous mode, with a wavelength of 790 nm, power of 100mW and fluency of 8 J / cm².
