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.
Obese patients are going to be submitted to indirect calorimetry pre-operatively and we are going to repeat the same exam 6 months after bariatric surgery (post Roux-en-Y gastric Bypass surgery). They are going to do also body composition analysis in both moments. The investigators are going to compare the results to see if the bariatric surgery increases their energy expenditure.
BACKGROUND: The fabrication of complete dentures traditionally involves a series of complex technical procedures. Those procedures include two impressions for each jaw, the registration of the relationship between the upper teeth and the patient's head and usually two appointments for tooth try-in. However, recent studies have questioned the real need for such complex procedures. Simplified methods could have similar results if compared with conventional ones, and dentures would be delivered faster and with lower costs. OBJECTIVES: This study aims to compare the effectiveness complete dentures fabricated with a simplified or conventional method. METHODS: Eighty edentulous patients who requested treatment by maxillary and mandibular complete denture in a public dental clinic inside the University of Sao Paulo - Ribeirão Preto Dental School will be randomly divided into two groups. Group S will receive new dentures fabricated by a simplified method, whereas Group C will received new dentures according to a conventional method. Participants will complete a questionnaire for denture satisfaction and the oral health-related quality of life, 3 and 6 months after treatment. At the same time, a specialist in dental prostheses will evaluate the quality of new dentures.
To evaluate the efficacy of the combination of mometasone furoate 0.1% and Salicylic Acid 5% in patients of both sexes who presented clinical symptoms of psoriasis of mild to moderate.
Infection, especially mediastinitis, is major complication in cardiac surgery. Considering that cardiopulmonary bypass (CPB) can alter kinetics of drugs, including antibiotics, the aim of this study was to evaluate the influence of cardiopulmonary bypass ( CPB) on plasma concentrations and pharmacokinetics of cefuroxime, administered prophylactically, in a 1.5g dose, followed by three bolus of 750mg every 6 hours, for 24 hours, in 19 patients undergoing coronary artery bypass graft (CABG) with CPB (CPB Group, n = 10), or without CPB (Off-Pump Group, n = 9); and assess whether the proposed dosing regimen is adequate to maintain plasma concentrations above 16 g/L (4 times the MIC) for the first 24 hours after the beginning of surgery.
The loratadine-pseudoephedrine combination has proven to be more effective than the use of these individual components. This prospective, randomized, double-blind and paralel study, in which patients with perennial allergic rhinitis receive one of loratadine + pseudoephedrine association drug for treatment of signs and symptoms during 4 weeks.
This study is an open-label, 6 month trial, of immediate release methylphenidate (MPH-IR) for children with ADHD aimed at assessing whether the observable behavioral changes seen during treatment are associated with potentially more stable underlying modifications in brain functioning (resting-state functional connectivity). Additionally, we will also be looking at treatment effects on neuropsychological processes and reading skills. This information will contribute to the first Brazilian study assessing the cost-effectiveness of the treatment of ADHD. Children with ADHD will be compared to a sample of sex and age-matched sample of typically developing children.
The aim was to verify the Pharmacokinetics and Pharmacodynamics of alpha interferon product-2A - Blausiegel, taking as the comparator drug product Roferon ® A (interferon alpha-2A - Roche Laboratory).
The purpose of this study is to determine if the use of tranexamic acid prior adenotonsillectomy in children can reduce surgical and postoperative bleeding.
Is the primary objective of this investigation to compare the clinical efficacy of the drug test - Ster ® (prednisolone 1% ophthalmic suspension - Union Chemicals) in the comparator - Fort ® Pred (prednisolone 1% ophthalmic suspension - Allergan) in the control of postoperative inflammation in cataract surgery by phacoemulsification through periodic measurement of efficiency scores (number of cells in the anterior chamber, the presence of fibrin in the anterior chamber, conjunctival hyperemia, corneal edema and Descemet folds).
Congenital central hypoventilation syndrome (CCHS) is a rare disorder of respiratory control characterized by ventilatory impairment that results in arterial hypoxemia. Although patients typically present this disease as newborns and rarely in later infancy, there have been reports of patients presenting with CCHS in adulthood. The present study reports a unique familial case in which the father (proband) presented late-onset CCHS with an expansion mutation of the Phox2B gene that was confirmed by genetic analysis. Surprisingly, the proband did not report any manifestation of the disease during childhood, and the disease progressed following an insidious course until adulthood. At the time of diagnosis, he did not present signs of pulmonary hypertension and right-side heart failure. The patient responded well to nocturnal invasive ventilation. In contrast, his son presented CCHS as a newborn with the full complement of symptoms while his daughter did not. The present report shows that CCHS cases characterized by a mutated Phox2 gene can progress without many symptoms and that the treatment approach used here was efficient for controlling the course of the disease. Furthermore, this case indicates that incomplete penetrance can occur. Genetic screening of family members is mandatory to evaluate the reproductive risk of the disease, especially because asymptomatic mutation carriers may be at high risk to develop the disease and transmit it to the next generation.
