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.
This prospective study was performed to compare two ophthalmic viscosurgical devices, DisCoVisc (hyaluronic acid 1.6% - chondroitin sulfate 4.0%) and hydroxypropylmethylcellulose 2% in terms of their overall clinical performance during phacoemulsification.
Permanent dependency of breathing apparatus due to spinal cord injury is traditionally treated with different types of mechanical ventilation. However, the electric ventilation became a possibility through their most current versions, such as diaphragmatic pacemakers. Diaphragmatic pacemakers rhythmically stimulates the diaphragm to replace the functions of the respiratory center that doesn't works well or is inaccessible. However, this modality has the prerequisite that the phrenic nerve and diaphragm muscle are normal. The reason for the development of diaphragmatic pacemaker freeing the patient from the ventilator. By using the mechanical energy of the diaphragm of the patient, the patient may come not need the ventilator tubing, tracheostomy, and with the help of their caregivers, the inconvenient mechanical ventilators.
This will be an open randomized clinical trial involving pregnant women between 35 and 37 weeks randomized to two modalities of exercise: treadmill or stationary bike. The study hypothesis is that exercise on a stationary cycle causes less maternal and fetal effects in relation to treadmill exercise.We will study the acute effects of exercise for both the mother and the fetus, monitoring the parameters before, during and after exercise for 20 minutes. The exercise intensity will be moderate, remaining between 60% and 80% of maximum heart rate. Women will be monitored with a recording equipment of ABPM (ambulatory blood pressure monitorization) and continuous cardiotocography and blood will be collected to measure blood glucose, total cholesterol and HDL, nitrate and lactate before, during and after exercise. The analysis variables are: maternal heart rate and blood pressure, fetal heart rate, number of fetal movements, transient accelerations, decelerations, short-term variability, episodes of high variability, uterine tone, glucose, lactate, nitrate, total cholesterol and HDL.The analysis will be based on intention to treat, according to the recommendations of the CONSORT (2010).
Rubber band ligation is a widely adopted treatment of internal hemorrhoids in busy coloproctology institutions. All three major hemorrhoidal clusters (left lateral, right anterior and right posterior) use to be ligated in order to obtain therapeutic success. It is commonly performed either through the ligation of a single hemorrhoid per session spaced by some few weeks to the second and third sessions, or of all three major hemorrhoids in one single session. Advocates of either method of hemorrhoidal ligation have arguments to defend their choice in terms of advantages, supported mainly on personal preferences. The investigators objective is to determine, through a controlled double-blinded randomized study, if there is any superiority of single hemorrhoidal ligation per session (in a total of three sessions) over the method of ligation of all three main hemorrhoids in a sole session in terms of therapeutic success (resolution of pre-ligation symptoms), morbidity, patient satisfaction and costs (institutional, labor and patient-related).
This study is a pain intensity evaluation in patients with myofascial pain submitted kinesitherapy after trigger point injection.
The purpose of this study is to determine whether pentoxifylline associated to pentavalent antimony has a higher cure rate than pentavalent antimony alone in the treatment of cutaneous leishmaniasis.
People with HIV have a high chance of becoming infected with TB, especially when they live in areas where TB infection is common. It can be difficult to diagnose TB in people who need to start HIV treatment right away. Within about 6 months after starting HIV treatment, some of these people can become very sick with TB and can even die from it. This study was being done in people who were starting HIV treatment and who lived in areas where the TB infection rate is high. The purpose of this study was to test an experimental approach to TB treatment to see if it is better than the usual approach. The experimental approach was to start TB treatment at the same time as HIV treatment, even when TB infection had not been found. The usual approach was to start TB treatment only if TB infection was found. In this study, half of the people started TB treatment at the same time as they started their HIV treatment. The other half started TB treatment only if TB infection was found. The study also tested how safe and effective it was to start TB treatment at about the same time as HIV treatment even when TB infection had not been found. The study collected information about diet, whether (and when) people in the study became sicker or died, how well their HIV was controlled, how they were feeling, how they were taking their medications, whether it mattered where they lived or what kind of HIV and TB care was standard, how many people were diagnosed with TB while in the study, and how the cost of the two treatment options on a national level could be compared.
This is a prospective, multi-center, open-label, single-arm, non-randomized, Phase II study to evaluate the efficacy and safety of TKI258 as second-line therapy in patients with either FGFR2 mutated or wild-type advanced and/or metastatic endometrial cancer.
The purpose of this study is to assess the effect of an educative program including telephone follow-up for burn patients regarding the impact of this intervention on the health status and return to work at six months after hospital discharge.
Objectives: The overall objective is to monitor efficacy of mebendazole (MBZ) against Soil-Transmitted Helminths (STH). The primary objective is: (1) to monitor the efficacy a single dose 500 mg of mebendazole (MBZ) against Soil-Transmitted Helminths (STH) infections by means of Faecal Egg Count Reduction (FECR) and Cure Rate (CR). The secondary objectives are: 1. to assess the occurrence of Necator americanus and Ancylostoma duodenal. 2. to assess the occurrence of β-tubulin mutations related to resistance before and after drug administration. 3. to evaluate the role of dogs and pigs as reservoir for zoonotic transmission.
