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.
Inadequate care during pregnancy and postpartum are predisposing factors for the emergence of nipple fissures. The therapeutic approach of nipple trauma care guidelines aimed at the breast and the appropriate techniques for breastfeeding. These measures, however, have a much more preventive than curative, it is not, in most cases, sufficient to power the closing of nipple trauma. The objective of this study was to evaluate the effectiveness of a phototherapy device designed specifically for the treatment of nipple trauma.
This randomized, double masked, multi-center study is being conducted to support the safety and efficacy of FST-100 for the treatment of acute viral conjunctivitis. The study intends to show superiority of FST-100 ophthalmic suspension compared to vehicle for clinical resolution of acute viral conjunctivitis.
This multicenter, randomized, open-label, parallel-group study will evaluate the efficacy and safety of subcutaneously administered rituximab in comparison with observation only as maintenance therapy in participants with relapsed or refractory indolent Non-Hodgkin's lymphoma (NHL). All participants will receive induction therapy with rituximab (375 milligrams per square meter [mg/m^2] intravenously [IV] in Cycle 1, then 1400 mg subcutaneous [SC] every 3-4 weeks) plus standard chemotherapy for 6-8 months; followed by 24 months of maintenance I period with rituximab (1400 mg SC every 8 weeks). Participants completing therapy and showing partial or complete response will be randomized to receive either rituximab (1400 mg SC every 8 weeks) or observation with no treatment during maintenance II period and will be followed for at least 15 months. Anticipated time on study treatment is until disease progression, unacceptable toxicity or end of study, whichever occurs first.
Treatment response of mild obstructive sleep apnea (OSA) to continuous positive airway pressure (CPAP) therapy and oral appliance (OA) is still controversial. The aim of this study is to evaluate the effect of CPAP and OA treatment on: objective and subjective sleepiness, cognitive deficits, mood changes, quality of life, inflammatory profile and metabolic cardiovascular and hormonal alterations in mild OSA subjects. Subjects with mild OSA (apnea -hypopnea index of 5 or more events per hour of sleep and less than 15), both genders, body mass index lower than 35Kg/m2 and age between 18 to 65 years will be included. They also must have a minimum mandibular protrusion of 7mm. Subjects will be randomly distributed in three groups: group 1 with CPAP, group 2 with OA and group 3 will be the control. At baseline evaluation, six months, one year and three years, all subjects will be submitted to sleep questionnaires, physical examination, ear-nose and throat evaluation, baseline polysomnography (and with CPAP for groups 1), Epworth Sleepiness Scale, Karolinska Sleepiness Scale, Stanford Sleepiness Scale, Maintenance of Wakefulness Test, Chalder Fatigue Scale, Neurocognitive testing, Beck Inventories of anxiety and depression, Functional Outcomes of Sleep Questionnaire (FOSQ), WHOQOL-BREF quality of life questionnaire, Short Form-36 quality of life questionnaire, questionnaire for sexual dysfunction, blood analysis for inflammatory, metabolic and hormonal evaluation, assessment of heart rate variability, 24 hour blood pressure monitoring and endothelial dysfunction. Sleep hygiene care was offer to three groups. Analysis mean and standard deviation will be used for descriptive statistical and a general linear model will be applied for analysis within groups on different time.
Data obtained in hypertensive patients without diabetes suggest that increased association of non-pharmacological treatment in patients with diabetes and hypertension may be associated with an improvement in blood pressure control. Despite the beneficial results found, is not yet known the magnitude of the effect of a DASH diet associated with the stimulus of physical activity on BP in patients with type 2 diabetes. The beneficial effects on blood pressure of an additional non-pharmacological intervention to drug therapy may have an even greater impact in patients with treatment-resistant hypertension The aim of this study is to evaluate the effect of changes in lifestyle on blood pressure in patients with type 2 diabetes and hypertension resistant to treatment.
There are few randomized controlled trials comparing intraradicular posts used to restore endodontically treated teeth, especially considering cast posts and glass fiber posts. The investigators study will evaluate the clinical success rates of endodontically treated teeth restored with glass fiber posts or cast posts and metal ceramic crown. Individuals included in this study should present any tooth with endodontic treatment and need of intraradicular retention (post) on maxilla or mandible according to inclusion and exclusion criteria. Individuals will be randomly allocated into two groups: (1) endodontically treated teeth restored with fiber post and composite resin core and metal ceramic crown or (2) endodontically treated teeth restored with cast post and core and metal ceramic crown. A sample size calculation will be performed to establish the number of posts needed for comparison. All crowns and posts will be cemented with self-adhesive cement. Individuals will be examined by calibrated examiners, in years 1 to 3. The reason of failure will be categorized as root fracture, fracture of the post, post debonding, clinical and/or radiographical evidence of a gap between restoration and tooth or endodontic failure, tooth extraction, secondary caries, or marginal defects. The confidence level will be set in 95%.
Abstract: Objectives:[The goal is] to confirm if physical activity of medium intensity performed during gestation can influence the way of delivery, and observe the adherence to exercise among pregnant women with different education levels. Methods: Held at the Center for Breastfeeding Incentive in the city of São Sebastião, State of São Paulo (Brazil), between April 7, 2008 and April 14, 2009, the prospective study involved 66 primigravid women, who were divided into two groups: the exercise group (GE) that exercised regularly during pregnancy, and the other control group (GC) that did not exercise regularly during same period. The significance level adopted in this study was five per cent (p = 0.05).
Men who have sex with men (MSM) have an increased risk of developing anal human papillomavirus (HPV) infections, which can be a risk factor for anal cancer. HIV-infected women are also at risk of anal cancer. This study will evaluate the effectiveness of the Food and Drug Administration (FDA)-approved quadrivalent HPV vaccine, Gardasil, at preventing anal HPV infection in HIV-infected MSM and HIV-infected women.
The prevalence of obesity and Type 2 diabetes has increased dramatically worldwide. Research on Glycemic Index (GI) diets has been largely developed, however the combination with metformin in humans was not investigated yet. We hypothesized that the low-GI diet in combination with metformin would elicit greater improvements on glucose metabolism, lipid profile and body composition on overweight or obese type 1 subjects. This study aims to evaluate the metabolic effects of the adoption of dietary advice to follow caloric restriction high/low GI diets, and low-GI diet associated with metformin on glucose metabolism, lipid profile and body composition on overweight or obese type 1 subjects.
This is a prospective, randomized, open label, parallel-group, multicenter phase III study to evaluate the efficacy and safety of active specific immunotherapy with racotumomab plus best supportive care versus best supportive care in patients with advanced NSCLC who have achieved an Objective Response (Partial or Complete Response) or Stable Disease with standard first-line treatment. Also immunological parameters will be evaluated. Best supportive therapy will be administered to all patients in the study according to institutional standards and includes any subsequent onco-specific therapies. 1082 patients will be included in the study, with non-small cell lung cancer in stages IIIA (non-resectable), IIIB or IV.
