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 aim of this study is to investigate the effects of the application of a citric acid + tetracycline gel solution during 90 or 180 seconds compared to no conditioning in the outcomes of treatment of Miller's class I or II recession defects by subepithelial connective tissue graft.
The purpose of this study is to characterize the safety profile of benralizumab administration in asthma patients who have completed one of the three predecessor studies: D3250C00017, D3250C00018 or D3250C00020.
Objective: To evaluate the effectiveness of online systematic brief psychodynamic psychotherapy (SBPP) via HIPAA compliant web conferencing on adults with neurotic disorders. Design: Randomized controlled trial. Single blind. Setting: Internet users in the community, in São Paulo, Brazil. Participants: Thirty-two adults will be randomly allocated to a group will receive online systematic brief psychodynamic psychotherapy (n=16), or a waiting list group (n=16). Method: Systematic adaptative diagnosis system will be applied in both groups at pre-treatment and post-treatment (or post-waiting list). Assessment will be a comparison of the adaptative diagnosis evolution between groups. Primary Outcomes: The subjects treated with online brief systematic psychodynamic psychotherapy will present an increase in their adaptative efficacy measured by systematic adaptative diagnosis scale (SADS) in comparison to the waiting list group, when contrasting their initial and final adaptative diagnostics.
There is no randomized controlled trial (RCT) comparing Conformal Radiotherapy (3DCRT) versus the Intensity Modulated Radiotherapy (IMRT) in terms of toxicity and disease control. Data from retrospective studies show that IMRT reduces the risk of severe late complications. More recently, the results from the RTOG 0126 study have also confirmed the benefit from IMRT in reducing acute toxicity for prostate cancer treated with conventional dose escalation. Therefore, to investigate the real clinical benefit of the IMRT over 3DCRT using a hypofractionated schedule in prostate cancer, the investigators developed a RCT.
The purpose of this study is to compare the radiographic progression-free survival (rPFS) of apalutamide in combination with abiraterone acetate (AA) plus prednisone or prednisolone (AAP) and AAP in participants with chemotherapy-naive (participants who did not receive any chemotherapy [treatment of cancer using drugs]) metastatic castration-resistant prostate cancer (mCRPC) (cancer of prostate gland [gland that makes fluid that aids movement of sperm]).
The main purpose of this study is to evaluate the effectiveness of VAMOS program, a physical activity and healthy eating promotion program, in hypertensive from Recife-Pernambuco- Brazil. Approximately 90 subjects with a diagnosis of hypertension, under anti-hypertensive medication and classified as non-physically active, will be selected and randomly distributed into two groups: a change behavior group (CBG) and control group (CG). The CBG will participate of a change behavior program, entitled VAMOS - Active Life Improving Health, for 12 weeks and composed of a weekly meeting, in group, lasting about 90 minutes. In each weekly meeting, will be presented and discussed guidelines and strategies for practical physical activities in different fields and for adoption of a healthy diet in order that the level of physical activity and eating quality improve. The program will be evaluated by effectiveness, implementation and maintenance (initial and individual level) dimensions of RE-AIM framework. The effectiveness will be assessed from anthropometric measurements, body composition, eating habits, physical activity level, stages of self-change, self-efficacy, social support, quality of life and assessment of cardiovascular function at rest (clinic and home blood pressure, arterial stiffness, blood flow and flow-mediated dilation, heart rate and heart rate variability) before and after 12 weeks of intervention. The implementation will be assessed by identifying the extent to which the program will be conducted as planned. The maintenance, initial and at individual level, will be estimated from revaluations of all outcomes, as measured before and after the intervention, three months after the end of the program. For data analysis, in addition to descriptive statistics, two-way ANOVA for mixed models wil be applied for for within and between groups comparison, if the premises of this test are met. The level of significance that will be adopted is P<0.05. All analyzes will be done at SPSS statistical package, version 17.0.
Cesarean section is the most performed abdominal surgery in women, worldwide. The World Health Organization (WHO) considers 15% of deliveries the ideal rate of this surgery. However, Brazil presents the highest rates of cesarian section in the world, reaching 85% in hospitals and private clinics. The most used technique of cesarean section is the known as Pfannenstiel or Classical technique. In 1996, a new technique was described, called Misgav Ladach or minimally invasive technique. Several studies have show that the minimally invasive technique is faster and promotes lower costs and less intraoperative bleeding. There is no current evidence that this technique is less painful. This study aims to compare the postoperative pain in both techniques,by means of two pain scales: a one-dimensional scale, the Visual Analogue Scale, and a multidimensional scale, the McGill Scale.
The present study aims to assess through surface electromyography, the effectiveness of proprioceptive neuromuscular facilitation protocols in the activation of the stabilizing muscles of the scapula and the anterior tibial muscle.
The objective of this study was to evaluate the effects of a school-based exercise program on posture, trunk range of motion and musculoskeletal pain in schoolchildren. This study was a Randomized controlled trial. The hypothesis was that the exercise group would have the postural deviations corrected, would have the trunk range of motion increased and would have the prevalence of pain decreased, while the control group would have not. Three schools from Brazil participated. The students that have been included (n=300) were randomly allocated to experimental (EG) or control group (CG). The intervention for EG consisted in a program based on stretching and strengthening exercises, applied twice a week, for eight weeks, with group sessions of 50 minutes. CG did not perform any intervention. Qualitative and quantitative postural evaluation (PAS/SAPO), musculoskeletal pain (self-report) and trunk mobility were collected.
Primary Objective: To evaluate long-term safety of alemtuzumab. Secondary Objectives: - To evaluate long term efficacy of alemtuzumab. - To evaluate the safety profile of participants who received other Disease Modifying Treatment (DMT) following alemtuzumab treatment. - To evaluate participant-reported Quality of Life (QoL) outcomes and health resource utilization of participant who received alemtuzumab. - To evaluate as needed re-treatment with alemtuzumab and other DMTs.
