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.
Introduction: Recent studies have suggested that other medications may be superior to amiodarone in controlling ventricular arrhythmias. However, a prospective and randomized comparison with lidocaine has not yet been described. Objective: This study aims to evaluate the effectiveness and safety of the use of amiodarone versus lidocaine in patients with stable ventricular tachycardias. Methodology: For this, a unicentric, randomized and prospective study will be carried out, in which the two drugs will be administered in a comparative manner. Hospital data (test results, medical outcomes, arrhythmia reversal, complications) of patients will be analyzed for safety and effectiveness. Expected results: The use of lidocaine is not inferior to amiodarone in the tolerability and reversion of stable ventricular tachycardias.
It is a randomized, double-blind, single-center, 30-day study. Patients aged 35-60 years, with apnea and hypopnea index and respiratory disturbance index normalized with CPAP, and Epworth Sleepiness Scale> 11. Patients undergo baseline and CPAP titration polysomnography, liquor and blood collection, Multiple Sleep Latency Test, anxiety and depression and cognitive assessments.
This is a randomized, open-label, multi-center, global, Phase III study to assess the efficacy and safety of durvalumab plus tremelimumab combination therapy and durvalumab monotherapy versus sorafenib in the treatment of patients with no prior systemic therapy for unresectable HCC. The patients cannot be eligible for locoregional therapy
Introduction: The level of physical activity decreases progressively with age. Elderly subjects who are physically active have lower rates of morbidity and mortality when compared to those inactive. Hospitalization leads to long periods of bed rest and physical inactivity, with consequent muscle atrophy, generalized weakness, and decreased independence and functionality. Therefore, preventing inactivity, loss of muscle strength and the worsening of functional performance during hospitalization may be a way to avoid loss of independence. And while movement has been increasingly promoted as an important part of the recovery of hospitalized patients, many of them still spend much of the time bedridden while in hospital. Objectives: To evaluate the impact of a guiding program on the importance of remaining active during hospitalization in relation to the level of physical activity, functionality and muscular strength of elderly patients and to identify the main barriers that impede them to perform physical activities in the hospital environment. Methods: Randomized and controlled trial which will include elderly patients admitted to the Respiratory Diseases and Medical Clinic wards of the Institute of Medical Assistance to State Public Servants, in São Paulo. The intervention group will receive verbal guidelines and one booklet on the deleterious effects of hospitalization and the importance of staying active during hospitalization. All patients will be evaluated through accelerometry to identify the level of physical activity during hospitalization. Functionality will be evaluated through the DEMMI scale, muscular strength through handgrip and the main barriers to stay active during hospitalization by applying a questionnaire. The days of hospitalization and the clinical complications presented by the patients during the stay in the hospital will be noted. The difference of the outcomes of the level of physical activity and functionality before and after the intervention will be compared between the control and the intervention group through a t-test. The length of hospital stay will be analyzed by the Kaplan-Meier test and the incidence of complications by the chi-square test.
Kinesio taping (KT) has been commonly used in rehabilitation in children with Unilateral Cerebral Palsy (UCP). However, there is a lack of studies that verified the effects of KT in CP. We aimed to verify the effects of KT in the performance of sit to stand movement (STS) in children with spastic UCP (USCP). A blinded, placebo and repeated-measure design was applied. The setting was the rehabilitation clinic of the university and care facilities. Eleven children, aged from 6 to 12 years old (10.5±-2.8 years), diagnosed with USCP, Gross Motor Function Classification System levels I and II were evaluated. KT was applied over rectus femoris (RF) muscle of the affected limb. We considered three taping conditions: KT, without KT (with tension) and placebo (KT without tension). Mean root mean square (mRMS) of RF; initial, final and peak angles, and range of motion of trunk, pelvis, hip, knee and ankles joints; and total duration of STS were considered. STS was evaluated from three seat heights, neutral (100%), lowered (80%) and elevated (120%). Mixed ANOVA test was applied for angular variables of hip, knee and ankle, and mRMS of RF. Repeated ANOVA was applied for angular variables of trunk and pelvis, total duration.
This is a multicenter, multinational, double-blind, 1:1 randomized, parallel-group, equivalence Phase 3 study to compare the efficacy and safety of MB02 plus chemotherapy (carboplatin and paclitaxel) versus Avastin® plus chemotherapy (carboplatin and paclitaxel) in subjects with Stage IIIB/IV non-squamous NSCLC
Self paring study, double blind placebo controlled with chronic tinnitus patients attended at the Tinnitus Research Group HC- FMUSP, complaining of neck and/or cervical pain and with myofascial trigger point in the head, neck and/or shoulder. They were submitted to a complete otolaryngologist evaluation which included history, physical examination and myofascial trigger point checkup. Patients also performed blood tests, tonal and vocal audiometry, and psychoacoustic tinnitus measures. Self paring study, double blind placebo controlled. Each patient will be subjected to the dry needling placebo, 4 sessions, 1 per week, with placebo stretching, followed by washout period of two weeks, and 4 more dry needling therapeutic sessions and active stretching. On the first day of the study will be conducted the following evaluation: questionnaires THI and NDI, quantification of cervical pain and tinnitus through the Visual analogue scale (VAS), search and confirmation of the presence of PGM and cervical pain, psychoacoustic measures and somatic tests. This evaluation will be repeated at the end of the four placebo sessions, at the beginning of therapeutic needling sessions and at the end of the same.
This randomized, crossover sham controlled trial with sham intended to study the effect of electrical stimulation on peripheral nerve (spinal accessory nerve) with acupuncture needle in healthy subjects aims to access the effect o electrical stimulation of accessory spinal nerve in cortical activation, muscular perfusion and autonomic response in healthy subjects. Participants will be assessed through measure changes in cortical activation, local muscular peripheral perfusion and autonomic responses before and after intervention and intervention-sham, and crossed after a period of wash-out. The design aims to contribute to assessment of one electroacupuncture's techniques by measuring some of the physiological effects caused by peripheral stimulation.
Chronic otitis media is a prevalent medical condition, leading to important impact in the lives of the individuals with this condition, and a great amount of patients may need surgical intervention. The main objectives of the surgery in these cases are to restore the anatomy of the middle ear, to improve hearing and to remove the infection to avoid further complications. Still, chronic otitis media with cholesteatoma presents high rates of recurrence and residual symptoms after surgery. The standard technique used for treatment of chronic otitis media is microsurgery. Nonetheless, with the development of new technologies that use endoscopy, it is now possible to use endoscopic surgery to improve the visualization of the cholesteatoma and ear structures by combining both techniques. This study will evaluate the efficacy of the combined access surgery technique, which is microsurgery combined with endoscopy, for closed tympanomastoidectomy in patients with cholesteatoma. Furthermore, the study aims to compare the results of the combined access technique and the standard technique by randomizing the patients in two groups: one group will receive tympanomastoidectomy by standard technique and the other group will receive combined technique.
