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 Zika infection is a viral disease that is transmitted to humans by the same mosquito that transmits Dengue and Chikungunya fever. The Zika virus has been found in various body fluids such as urine, blood and semen, but we do not know how long it persists in these fluids. For example, parts of the virus were reported to persist in semen after six months of the onset of symptoms, but we do not know if the virus can stay longer. In this way, we want to investigate how long the Zika virus can be found in other secretions besides blood and urine. Study Hypothesis: ZIKV can be shed in human body fluids long after the time of the acute infection. Persistence of ZIKV in different body fluids may vary due to the influence of circulating specific ZIKV IgM and IgG, as well as host and environmental factors.
The objective of this randomized controlled clinical study was to evaluate the increase in the volume of peri-implant gingival tissue in implants installed in the aesthetic areas with the use of subepithelial-conjunctive tissue graft, and a sample of 40 individuals with implants Aesthetics where the test group (n = 20) will receive tec graft. (N = 20) will receive only the dental implant without the placement of a tec graft. Epithelial-conjunctival.
Despite the high success rates of gastric bypass in the short and long terms, little is known about possible anatomopathological changes that can occur in these patients. The objective is to investigate preoperative and postoperative endoscopic changes in patients undergoing gastric bypass without a ring. Thirty obese patients from different regions of the country with the surgical indication for the Roux-en-Y gastric bypass will be studied prospectively. All patients will be submitted to upper gastric endoscopy (UGE) two, six and 12 months after the surgical procedure at the Kaiser Clinic. This study will identify whether there are endoscopic changes within one year after the surgery and what they are. Changes, if they exist, will be correlated with clinical data, in order to make an accurate prognosis of the patient, thereby contributing to the outcomes of future patients submitted to this type of procedure.
To evaluate subjectively and objectively the quality and efficacy of local anesthetic block with mepivacaine in simple extraction of mandibular molar. Provide and collect information such as: signs and symptoms, quality of anesthetic block, quantify pain and / or discomfort, as well as medication used, both preoperatively and postoperatively.
The aim of this study is to evaluate the effects and validate news physiotherapy techniques: robotic rehabilitation, virtual reality, vibration therapy, canoeing and hand cycling in the secondary clinical complications of the breast cancer, through the Biomedical Instrumentation. It will be realized the double-blind longitudinal clinical study. Will participate in the study 100 women post breast cancer surgery, the volunteers will be allocated in the respective modalities treatment; and 20 healthy volunteers, will be only the control group. The volunteers conducted 10 physiotherapy session, and it will be evaluated after, during and before of the treatment, to evaluated myoelectric activity, scapular and hand muscle strength, range of motion, circumference of the upper limbs and quality of life. Expected to Positive Results With regard to the minimization of pain intensity and lymphedema, favoring the improvement of range of motion of the shoulder joint, myoelectric activity, increased muscle strength, and consequently improves the quality of life.
The purpose of this study is to evaluate the efficacy and safety of risankizumab versus placebo during induction therapy in participants with moderately to severely active Crohn's disease (CD).
This is a 2-part trial: a Phase 1, open-label, dose-escalation study in subjects with metastatic or locally advanced solid tumors, with a consecutive Phase 2 expansion to evaluate efficacy in subjects with recurrent, unresectable, or metastatic (advanced) cervical cancer that has progressed after a platinum-based treatment regimen.
This study includes two periods. The main objective of Period 1 is to compare the efficacy of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo and versus adalimumab (Humira®) in participants with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response to non-biologic DMARDs (DMARD-IR). Period 1 is also designed to compare the efficacy of upadacitinib 15 mg and 30 mg QD versus placebo for the prevention of structural progression. The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg and 30 mg QD in participants who have completed Period 1.
The study objectives of Period 1 are to compare the efficacy, safety, and tolerability of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo for the treatment of signs and symptoms in adults with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response or intolerance to biologic disease-modifying anti-rheumatic drug (bDMARD). The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg QD and 30 mg QD in participants who have completed Period 1.
Of the patients diagnosed with ST-segment elevation myocardial infarction (STEMI) who underwent reperfusion therapy and have thrombolysis in myocardial infarction (TIMI) 3 flow, about 40% have flow alterations in the coronary microcirculation, which leads to worse remodeling of the left ventricle with a consequent increase in the mortality of this population. Clopidogrel is the only known antiplatelet medication that brings benefits to the coronary microcirculation. Ticagrelor is significantly superior to clopidogrel in terms of decreasing mortality. The main objective of this study is to compare the effect of ticagrelor versus clopidogrel on the coronary microcirculation by the Myocardial Perfusion Score Index (MPSI) obtained using Microbubble Contrasted Echocardiography (MCE) in patients who have STEMI and treated with thrombolysis.
