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.
It is a controlled clinical trial randomized, double-blind evaluator. Will be considered eligible patients, individuals of both sexes, aged 40 -60, to submit at least four items of knee osteoarthrosis classification criteria, according to the American College of Rheumatology, pain above four points in the visual analogue scale (VAS), diagnosed with knee osteoarthritis and who sought physical therapy treatment. Patients will be randomized by a number sequence generated by a computer using Microsoft Excel (Microsoft Corporation, Redmond, Washington), in opaque envelopes by researcher who will not attend the study.Patients will be divided into two groups: group with knee patellar hole or group without knee patellar hole. Shortly after the selection of the knee, the patient will have his eyes blind or cover in order to keep it '' blind '' regarding the type of knee brace that it would use. Finally evaluator 1 will cover the knee with a black cloak, making the second evaluator ''blind '' regarding the type of knee brace that will be used. Two investigators will carry out the data collection. The first evaluator will collect information on the clinical characteristics of patients, including evaluation form, numerical pain scale, which measures the intensity of pain, test Time Up and Go (TUG) test that measures the basic mobility of movement and test walking eight meters, whose purpose is to measure the time that the individual takes to walk a distance of eight meters.
This study evaluates the non-inferiority of Cefaliv® compared to Neosaldina® in the treatment of migraine attack in two hundred and sixteen adults of both sexes with age between eighteen and sixty five years old. The first Half of participants will receive Cefaliv®, the other half will receive Neosaldina®.
Regional lymph node metastasis is a major determinant of local recurrence and overall survival rates in patients with colorectal cancer. Because of the poor prognosis associated with the presence of lymph node metastasis, stage III colorectal cancer patients should receive adjuvant treatment with chemo and / or radiation therapy according to the site of tumor. Several authors have investigated the use of revealing solutions for lymph node clearance in colorectal cancer. Most studies comparing conventional histopathological specimen examination to any lymph node clearing technique showed that the use of revealing solutions increases the mean number of lymph nodes harvested, usually in a statistically significant manner. It is still controversial the impact of the use of revealing solutions for upstaging of lymph node status and consequently for the indication for adjuvant therapy. Therefore will be conducted a randomized clinical trial to compares the performance of GEWF and Carnoy solutions for the histopathological examination of patients with colorectal cancer. The aim of this study is to determine the lymph node revealing solution with the best performance (increase in the mean number of lymph node harvested and lymph node upstaging) in patients with colorectal cancer.
One of the most effective strategies to decrease radiation exposure during ureteroscopy is to use low dose. However, the quality of the image obtained is inferior to full dose image. The main concern is to maintain the stone free and complication rate despite the inferior quality of image obtained. Our aim was to evaluate if reducing the dose of fluoroscopy to ¼ instead of full dose would impact in a reduction of total radiation exposure despite a possible increase in fluoroscopy time. Also, if this strategy would impact in operation time, stone free rate and complication rate of unilateral semi-rigid ureteroscopy for ureteral stone treatment due too less than optimal fluoroscopy image. All patients over 18 years old diagnosed with ureteral stone from 5 mm to 20 mm in diameter by CT scan were counseled regarding their treatment options. Patients who failed spontaneous passage or medical treatment or chose endourologic treatment were included in this study. Patients with abnormal urinary anatomy such as horseshoe kidney, pelvic kidney or duplex system were excluded from the study.
Thus, the aim of the current study is to assess the influence of vitamin D deficiency and, consequently, of serum calcium deficiency in the body composition, muscular activity, bone mineral density, fatigue, and exercise tolerance of CD patients. Secondly, it also aims to determine the impact of vitamin D supplementation on this population.
This is a prospective, randomized study, aiming to evaluate patients with Deep Venous Thrombosis in lower limbs and the recanalization rates evaluated with DUPLEX ultrasound, as so the clinical outcomes in patients submitted to oral anticoagulation with Rivaroxaban versus Warfarin.
The purpose of this study is to confirm that the pharmacokinetics of ibrutinib in pediatric participants is consistent with that in adults (part 1) and to assess efficacy (event-free survival [EFS]) of ibrutinib in combination with rituximab, ifosfamide, carboplatin, and etoposide (RICE) or rituximab, vincristine, ifosfamide, carboplatin, and idarubicin (RVICI) background therapy compared to RICE or RVICI background therapy alone (part 2).
Migraine is a common medical condition. Several studies suggest that obesity and/or weight gain are risk factors for aggravating migraine course, especially increase the frequency of headache episodes. The aim of the current study was to evaluate whether nutritional intervention would be able to improve clinical parameters (as assessed by MIDAS and HIT) of patients with migraine.
This study compare 2 techniques to treat difficult bile duct stones endoscopically
The purpose of this study is to evaluate and compare the effects of upper limb training with Induced Constraint Therapy (ICT) or robotic therapy. No placebo therapy is used. Motor function, neurological evaluations and quality of life are assessed for the comparison of the therapies.
