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 study hypothesis is an increase in muscle performance and a higher aerobic adaptation of young women submitted to chronic endurance training program associated to low level laser therapy when compared to chronic aerobic training alone.
Hypertension is a chronic disease that affects about 23% of the brazilian population. The treatment of hypertension by pharmacological intervention is efficacious, but has side effects and significant costs. Techniques that reduce the respiratory rate are shown as a effective non-pharmacological treatment in controlling blood pressure. Evidence has shown that a slow and deep breathing rate, around 10 breaths per minute or less, significantly reduces blood pressure. However, the physiological mechanisms involved in blood pressure decrease due to decreased respiratory rate are not yet known. Therefore the goals of this study will evaluate the chronic effect of breathing exercise guided on office and 24 hours blood pressure and analyse the chronic effect of breathing exercise guided over the autonomic function in hypertensive patients in stages 1 and 2.
The aim of the study is, primarily, evaluate the safety of the use of the silicone stent HCPA-1 in patients with clinically significant tracheal and/or bronchial stenosis. Secondarily, this study aims to evaluate the efficacy of the use of the silicone stent HCPA-1 who are in the same conditions described above and also estimate the costs the use of these silicone stents involve.
This is a prospective, randomized and comparative study is to quantify the functional and structural alterations of the macula in patients with proliferative Diabetic Retinopathy submitted to laser photocoagulation and to evaluate the efficacy of intravitreal bevacizumab as a adjuvant therapy in preventing the adverse events of that procedure. The patients with proliferative Diabetic Retinopathy (DR) with indication of binocular laser photocoagulation will be examined by ophthalmologists who will measure the visual acuity and contrast sensitivity, perform slit lamp examination, fundus examination and optic coherence tomography before and after laser photocoagulation. Laser photocoagulation will be performed in both eyes according Early Treatment Diabetic Retinopathy Study that advocate the realization of 3 episodes of laser photocoagulation in 3 weeks. This comparative study analyses the effect of intravitreal bevacizumab one week before laser photocoagulation and one, three and six months after the randomization visit. The fellow eye will be submitted only to laser photocoagulation and will be considered as control. It is estimated a sample of 30 patients. All procedures, purposes and methods will be explained to all patients.
- Saliva plays a key role in the homeostasis of the digestive tract - The reflux of gastroesophageal contents may cause damage to the esophageal, laryngeal and pharyngeal mucosas - There seems to be no correlation between the severity of reflux episodes and the intensity of inflammatory changes, suggesting individual protective mechanisms to refluxate exposure - Inorganic and Organic Salivary changes have been associated to Gastroesophageal Reflux Disease (GERD) and its supraesophageal manifestations, especially reflux laryngitis (Laryngopharyngeal Reflux- LPR) - Decreased salivary Epidermal Growth factor (EGF) concentrations have been found in patients with GERD and LPR, but it is unclear if these are primary or secondary to the disease. - Hypothesis: The decreased salivary EGF concentrations in patients with reflux laryngitis is primary and therefore would not change after treatment and control of the disease
The proposed project will be conducted to evaluate the influence of application resources associated with non-pharmacological during labor for pain relief and accelerated phase of expansion. Although mothers' access to resources for non-pharmacological pain relief during labor is recommended, is not seen as the application of routine obstetric practice, although it has been demonstrated benefits and scientific evidence with your application. It is believed that the implementation of associated application of non-pharmacological resources in assisting the labor can be introduced into daily practice in various hospitals in the country, minimizing pain and favoring the shorter duration of labor, decrease in use of painkillers and inductors, resulting in a reduction of complications, improves the comfort of the mother making her birth experience more satisfying and rewarding, being assisted with security and trained by multidisciplinary teams.
The main objective of this study is to evaluate the effectiveness of music education over a period of five months (three times per week, one hour per day) on the improvement of reading skills (decoding, prosody and phonological awareness) in children (8-10 years) with reading difficulties from poor neighborhoods in the city of Sao Paulo. A second objective is to develop a theoretical model that may explain how acquired musical skills are correlated with the supposed changes in each of the covariates and outcomes in this study. The study will be administered to 270 children with reading difficulties from 10 different schools (27 children per school). 135 children will have music lessons and 135 will not; therefore, 5 schools will be the control and 5 schools will be the intervention group. The analysis will consider the cluster structure, since the randomization was not conducted at the individual level (i.e., the school level was the randomization unit). For the inferential analysis, generalized estimation models and structural equation modeling will be used.
The investigators propose a randomized clinical trial comparing the effect of 30 mcg ethinyl estradiol and LNG 150 combination oral contraceptive pills versus placebo, or LNG-IUS or Etonogestrel-releasing contraceptive implant (Implanon)on breast-milk intake and infant growth in exclusively breastfeeding mother-infant pairs. Mother-infant pairs will be randomly assigned either 30 microgram ethinyl estradiol combination oral contraceptive pills or identical placebo to start on post-partum day number 42 or Implanon implants or a LNG-IUS. All women will be offered nonhormonal contraceptives prior to randomization. The pairs will then be followed for four weeks. During this follow-up period, breast-milk intake will be quantified by administering deuterium oxide to exclusively breast-feeding mothers and measuring the enrichment of deuterium oxide in the saliva of their infants, otherwise known as the dose-to-mother method of Coward.17 Additionally, maternal and infant anthropometric measurements will be collected -- both as a value necessary to implement the breast-milk quantification method, as well as an outcome for analysis, and a daily diary will be kept by the women participating in the study that records infant feeds and diaper changes.
There is limited information on the long-term effects of treating patients with MPS VI with Naglazyme® and limited data on the natural history of treated and untreated MPS VI patients. The Re-survey Study ASB-00-03 will assist in understanding the effects of long-term Naglazyme treatment and the natural history of the MPS VI patient population.
The purpose of this study is to evaluate the impact of an educational program for people with diabetes mellitus based on the family social support.
