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.
Heart failure is one of the major causes of hospitalization in Brazil and worldwide. Recent studies attempt to identify readmission and prognostic markers at the time of discharge from these patients. The reassessment and possibility of early therapeutic adjustment may be relevant in this context. Therefore, the prospective and randomized comparative use of early re-evaluation in Hospital-day versus non-intervention group has not yet been described. The objective of this study was to evaluate the impact on the re-hospitalization rate in 30 days of the early re-evaluation of the patients in the day-hospital versus the non-intervention group in heart failure. For this, a unicentric, randomized and prospective study will be performed, in which the Hospital-Day strategy is performed versus no intervention in a comparative manner. Hospital data (test results, medical outcomes, complications) of patients will be analyzed for safety and effectiveness. The hypothesis of this study is that the Hospital-Day strategy is superior to the non-intervention strategy and causes fewer rehospitalizations within 30 days.
Introduction: Recent studies have suggested that trimetazidine may help reduce myocardial damage following percutaneous coronary intervention. However, the evaluation of the potential of this medication in the reduction of myocardial damage in patients with diabetes mellitus and unstable angina, in a prospective and randomized way, has not yet been described. Objective: The aim of this study was to evaluate the efficacy and safety of the use of trimetazidine versus placebo in patients with diabetes mellitus and unstable angina undergoing coronary stent angioplasty. Methodology: For this, a unicentric, randomized, double blind and prospective study will be performed in a comparative manner. Hospital data (test results, medical outcomes, drug dose, complications) of patients will be analyzed for safety and effectiveness. Myocardial damage will be measured by means of ultrasensitive Troponin dosages. Expected results: The use of trimetazidine reduces myocardial damage in patients with diabetes mellitus and unstable angina undergoing coronary stent angioplasty.
Amiodarone is considered the medicine of choice in heart rate control in critically ill patients with atrial fibrillation with high ventricular response. However, a recent retrospective study showed a greater number of events in critical patients in whom there was an attempt to control versus in which there was no. Therefore, the prospective and randomized comparative use of amiodarone in this group of patients has not yet been described. The aim of this study was to evaluate the safety of the use of amiodarone (restricted group) versus placebo (liberal group) in heart rate control in atrial fibrillation with high ventricular response in patients with sepsis and vasopressor cardiovascular dysfunction. For this, a unicentric, randomized, blind and prospective study will be performed, in which the restrictive versus liberal strategy is performed in a comparative way. Hospital data (test results, medical evolutions complications) of patients will be analyzed to calculate safety and effectiveness. Expected results: The liberal strategy is superior to the restrictive strategy and causes fewer adverse events.
A prospective study to evaluate and compare implants placed in preserved versus non-preserved extraction sockets using L-PRF (Leucocyte- and platelet-rich fibrin) after 1, 3 and 5 years.
The purpose of this study was to evaluate the efficacy and the safety of bumetanide/S95008 in the improvement of Autism Spectrum Disorder core symptoms.
The purpose of this study was to evaluate the efficacity and the safety of bumetanide/S95008 in the improvement of Autism Spectrum Disorder core symptoms.
The aim of this open-label (OL) extension trial is to study the long-term safety and efficacy of macitentan in subjects with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease (PVD) beyond the treatment in the double-blind parent SERENADE study (AC-055G202, NCT03153111). Furthermore, this OL extension study will give eligible subjects of the main study (SERENADE/AC-055G202, NCT03153111) an opportunity to continue or start receiving macitentan.
Chronic low back pain interventions may include exercises, manual therapy, health education, and pain education, strategies based on psychological or behavioral change approaches, as well as biopsychosocial interventions. Pain self-management programs basically aim to engage the participant in activities, stimulating the patient to be more active in life and live despite the pain. However, pain neuroscience education is a new approach recognized as therapeutic patient education (ETP) and is best described as a form of cognitive rather than behavioral therapy. However, there are few studies in the literature comparing those types pain education. Thus, the purpose of this study will be to compare the immediate effects of an educational program focused on Pain Neuroscience Education vs. Pain self-management educations for patients with chronic low back pain considering the outcomes of pain intensity, catastrophizing and pain self-efficacy.
It is known that the low back pain can cause discomfort and deconcentration during the flight, requests for abstention of flight, fear in the aviators about the future in case of illness and economic damages to the country. However, there are few studies about the incidence, prevalence or risk factors associated with low back pain in Brazilian air force pilots. Also, the literature lacks further randomized controlled studies about interventions, leaving a huge field to be explored in future research. Objectives: This study to analyze the chronic effects of an exercise protocol on lumbar pain in Brazilian Air Force pilots. Materials and methods: The study is a blind and randomized clinical trial, in which a protocol of strength and lumbar resistance exercises will be tested. The volunteers will be: 20 fighter instructors with intermittent low back pain. Such volunteers will be recruited in a non-probabilistic manner for convenience. Moreover, they will be randomly distributed through www.randomization.com to form two groups with 10 members each: experimental group (EG), where they will participate in an exercise program three times a week for 8 weeks; and the control group (CG), in which they will receive explanation and handbook demonstration of the same exercises (Appendix 1) - after 8 weeks of intervention and after being reevaluated. The study will be performed at the city of Natal/ Rio Grande do Norte. The evaluation will consist of an evaluation form with personal data, anthropometric data, occupational information, health history, physical exercise pattern and pain information, quantified by Visual Analog Pain Scale. In addition, the Oswestry questionnaire will be administered to assess lumbar function and the Nordic Questionnaire to assess musculoskeletal changes. Also, will be done: postural evaluation, using a postural evaluation software (SAPO); assessment of lumbar range of motion, using an IPHONE app called iHandy Level; Magnetic Resonance Imaging of the spine; dynamometry to measure the trunk extension force, flexion with rotation and lateral bridge, using the manual dynamometer Lafayette® - model 01165, USA; and resistance test of trunk stabilizing muscles. Magnetic resonance imaging will be done at the Onofre Lopes University Hospital. The project will be submitted to the Research Ethics Committee of the Federal University of Rio Grande do Norte through the national interface "Plataforma Brasil". The study will also be registered on the international clinical trial platform, ClinicalTrials.gov. Data analysis: The Statistical Package for Social Science (SPSS) software will be used in the analysis. The normality of data distribution and the homogeneity of the variances will be verified by the Kolmogorov-Smirnov (K-S) and Levine tests, respectively. If there is a normal distribution, the descriptive statistics will be performed through means and standard deviations. Significance level adopted: 5% (P <0.05). The paired t test was used for the comparisons between the measurements obtained in the pre and post 2 month evaluations, and for the comparison between the groups (CG and EG), the unpaired t test. If the data do not present a normal distribution, the Friedman test will be used for comparisons of the measures of the evaluations in each group and the Kruskal-Wallis test for comparisons between the groups (CG and EG).
Our long-term goal is to decrease cervical cancer incidence and mortality among women in low- and middle-income countries (LMICs) by using the most efficacious and acceptable screening method, particularly among women who do not come to the clinic for their regular Pap testing. The purpose of this feasibility study is to compare three cervical cancer screening modalities (self-collection and HPV testing, Pap testing at the public health clinic, and choice between self-collection and HPV testing and Pap testing) among women who have not undergone cervical cancer screening within the past four years using a theory-based, culturally relevant intervention implemented by Community Health Workers (CHWs) via door-to-door visits. Three Basic Health Units (BHUs) within the public health system will be randomly assigned to one of the three screening modalities/conditions (self-collection and HPV testing, Pap testing at the local public health clinic, and choice between self-collection and HPV testing and Pap testing). CHWs will invite women who report not having been screened for cervical cancer in the past four years to participate in the study, and deliver a brief educational/behavioral session on cervical cancer and screening using a door-to-door approach under of one of the three conditions. The primary outcome will be adherence to cervical cancer screening. We hypothesize that (1) Women in the "choice" and "self-collection" groups will be more likely to engage in cervical cancer screening and display higher satisfaction with their screening than women assigned to the "Pap" with women assigned to the "choice" group having the highest adherence of the three groups; and (2) Within the "choice" group, more women will choose and complete self-collection than Pap test.
