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 purpose of this study is to compare the efficacy of graded activity program and supervised exercise on pain, functional disability, quality of life, global perceived effect, return to work, physical activity, physical capacity and strength of the lower limbs in patients with chronic non-specific low back pain
The care of the oral cavity is an important way to prevent local and systemic infections. This study aimed to: evaluate the use of video as a teaching strategy of oral hygiene for patients undergoing chemotherapy. The methodological design used was quasi-experimental before-after intervention. The sample consisted of 23 subjects who performed the technique of oral hygiene before and after watching an educational video. To do so was given a kit with a toothbrush with soft bristles, toothpaste with low abrasivity, mouthwash or product to mouthwash and dental floss for oral hygiene. For data analysis we applied the parametric test t "Student" paired.
This open-label, randomized, 2-arm, multicenter, phase 3 study has the primary objective of comparing the modified progression-free survival (mPFS) obtained with brentuximab vedotin (ADCETRIS®) plus AVD (doxorubicin [Adriamycin], vinblastine, and dacarbazine; abbreviated A+AVD) versus that obtained with ABVD (doxorubicin [Adriamycin],bleomycin, vinblastine, and dacarbazine) for the frontline treatment of advanced classical Hodgkin lymphoma(HL)
Objectives: To compare the stability of implant surface treated by dual acid etching (Porous)and implants with anodized surface (Vulcano) over a period of 16 weeks after installation. Methods: it will be a clinical study with individuals with missing teeth requiring rehabilitation with dental implants in the maxilla and that fulfill the study inclusion criteria. The research sites will be randomized into two groups: the control group patient's sites receive implant surface treated by dual acid (AR Torque Porous, Connection Implant Systems, Aruja, Brazil) and in the test group implants with anodized surface (AR Torque Vulcano-Actives, Connection Implant Systems, Aruja, Brazil). The evaluation of the stability of the implants will be made over 16 weeks, through resonance frequency analysis with Osstell (Integration Diagnostics AB, Gothenburg, Sweden). Data will be analyzed using descriptive statistics and comparative.
A clinical research study to find out if it is safe to stop the drug nilotinib (Tasigna) in chronic myeloid leukemia (CML) patients. Patients who started treatment with imatinib (Gleevec) when they were first diagnosed with CML, then switched to nilotinib (Tasigna) for at least 2 years with the combined time on imatinib (Gleevec) and nilotinib (Tasigna) for at least 3 years and have very small amount of leukemia cells remaining after the nilotinib (Tasigna) treatment will qualify for the study.
This is a phase II step-wise, randomized, multicenter, double-blind and controlled clinical trial to evaluate the safety and immunogenicity of a attenuated tetravalent lyophilized dengue vaccine manufactured by Butantan Institute. Three Clinical Sites at University of Sao Paulo - Brazil will participate in the study. A total of 300 volunteers will be recruited and divided into two steps: Step A (with no previous exposure to dengue) and Step B (with and without previous exposure to dengue). In step A the participants will be assigned to receive either the lyophilized vaccine, or the liquid vaccine(developed at NIH and produced and formulated at Butantan according to the NIH-Protocol), or the placebo. In Step B participants will be assigned to receive either the lyophilized vaccine, or the placebo. Both vaccine formulations (lyophilized and liquid) are composed of the same attenuated viruses: rDEN1∆30, rDEN2/4∆30(ME), rDEN3∆30/31, and rDEN4∆30. At the end of the study, 20 volunteers will have received the liquid formulation (NIH), 210 the lyophilized formulation (Butantan), and 70 will have received the placebo. All participants included in both steps will be followed by a period of five years after their inclusion in the study. The study hypothesis is that the investigational lyophilized dengue vaccine manufactured by Butantan Institute is safe and confers balanced immune response, after one dose of 1000PFU, to all for vaccine viruses.
The principal aim of this study is to evaluate the presence of changes in cervical vestibular evoked myogenic potentials (VEMPc) after acute intake of caffeine in healthy subjects. Secondarily, it wants to standardize normal values exam VEMPc in otorhinolaryngology service of the hospital.
Prospective, observational Registry to obtain data on device performance and clinical outcomes.
This study aims to investigate the effectiveness and safety of mesotherapy for the treatment of female pattern alopecia. - Sixty female subjects between 18 and 65 years diagnosed with female pattern hair loss will undergo mesotherapy sessions weekly for ten weeks. - One group will receive 0.5%/2ml minoxidil application and a control group will receive application of placebo (saline 0.9%). - Biopsy of the scalp, trichogram and trichoscopy (Fotofinder) will be performed before and 08 weeks after treatment as a method objective evaluation of the response
Hypocalcemia is a frequent adverse event after thyroidectomy. It is usually related to hypoparathyroidism, but preoperative hypocalcemia, hypomagnesemia or vitamin D deficiency contributes to it. This study aims to determine the frequency of vitamin D deficiency or insufficiency in patients submitted to thyroidectomy, to define the risk attributed to vitamin D deficiency to postoperative hypocalcemia, to identify other factors associated to postoperative calcium disorder, and to evaluate the benefit of preoperative treatment of vitamin D deficiency to prevent postoperative hypocalcemia.
