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.
Patients with stable coronary disease when undergoing percutaneous coronary intervention may present periprocedural myocardial infarction defined at present as a creatine kinase-myocardial isoenzyme (CK-MB) elevation 3 times upper limit of normal, as a cut off for periprocedural myocardial infarction after PCI. Although percutaneous coronary intervention is associated with low rates of complications, periprocedural myocardial infarction has been touted as a negative factor in long-term clinical results . Several clinical, anatomical and technical associate to the occurrence of this event . Although randomized controlled trials and systematic reviews to statin pre intervention have targeted the administration of high-dose statin is recommended before surgery to reduce the risk of periprocedural myocardial infarction, there is no information on the impact of the maximum concentration plasma of statin at the time of percutaneous coronary intervention in stable patients on chronic statin use in preventing periprocedural myocardial infarction or the elevation of cardiac enzymes . The anti-ischemic effect of statins in percutaneous coronary intervention was mainly determined in statin -naïve patients or in patients with acute coronary syndromes . In this work , we studied the impact of the peak plasma concentration of statin at the time of percutaneous coronary intervention was studied through prospective randomized single center in stable patients with chronic statin divided into two groups . In the group (1) Experimental (n = 268 ) was administered at a dose of 40 mg rosuvastatin between one and six hours before surgery and group (2) control without rosuvastatin (n = 268). This range 1 to 6 hours is the time at the peak concentration of rosuvastatin in the blood after oral ingestion. The primary objective was to assess the incidence of periprocedural myocardial infarction by creatine kinase above three times upper normal limit in hospital period and as a secondary objective to analyze the elevation of any amount of creatine kinase on the baseline.
Evaluating neurobiological disorder associated with Attention Deficit Hyperactivity Disorder (ADHD) and the contribution of transcranial direct current stimulation (tDCS) in the adaptation of inhibitory control.
Objective: Trichotillomania is a psychiatric condition characterized by chronic pulling and plucking of one's own hair. Cognitive behavioral therapy shows promise as a treatment. However, there have been no randomized, controlled studies of the efficacy of group cognitive-behavioral therapy. Methods: We evaluated 44 subjects, whom met the criteria for a diagnosis of trichotillomania. Subjects were randomized to receive 22 sessions of either group cognitive-behavioral therapy or group supportive therapy (control).
This study aims to demonstrate the therapeutic efficacy and safety of Shampoo PIOLIN ® in the treatment of human pediculosis. Will be treated 212 patients aged 2-60 years with the infestation, along with the people in your family life. All will be submitted to the dosing regimen recommended in the package insert. 100% of the sample shall be subjected to clinical evaluation through comb, pre and post treatment and monitored after thirty days for evaluation of safety and possible adverse effects that may arise related to any of the components of the formula. The efficacy study is active comparator, non-inferiority.
The present study aims to evaluate the impact of a weaning strategy based on identification of early signs of respiratory distress by lung ultrasound and the consequent implementation of a "clinical optimization" protocol as compared to usual care.
This two-arm, randomized, open-label, multicenter study will evaluate the efficacy and safety of trastuzumab emtansine in combination with pertuzumab versus trastuzumab in combination with pertuzumab and a taxane as adjuvant therapy in participants with human epidermal growth (HER) factor 2 (HER2)-positive primary invasive breast cancer. Following surgery and anthracycline-based chemotherapy, participants will receive either trastuzumab emtansine at a dose of 3.6 milligrams per kilogram (mg/kg) and pertuzumab at a dose of 420 milligrams (mg) intravenously (IV) every 3 weeks (q3w) or trastuzumab at a dose of 6 mg/kg and pertuzumab at a dose of 420 mg IV q3w in combination with a taxane.
Therapeutic neovascularization is an innovative strategy for cardiac tissue recovery due to chronic, intense ischemia. Thus stem cell therapy has become a promising procedure for the large number of patients with refractory angina due to coronary disease, despite of the use of multiple anti-angina medications, remain severely symptomatic with disabling angina. Stem cell therapy using autologous cells from the patient's bone marrow, has been shown to be safe and associated with improved myocardial perfusion, reducing the symptoms of advanced coronary artery disease and increasing the functional capacity of patients whose therapeutic armamentarium available today has been exhausted. The study hypothesis was that the infusion of autologous mononuclear cells derived from the patient's bone marrow and delivered via intramyocardial injection in patients with refractory angina and normal or slightly depressed ventricular function, promote improvement in the anginal symptoms and myocardial perfusion by the inducing neoangiogenesis.
The most common surgical approach to perform a total knee replacement is called medial parapatellar approach. It's effective and can be applied virtually to all types of knee deformities. The Keblish approach is an alternative approach which uses the lateral side of the patella to enter the joint. Some orthopaedic surgeons consider the latter approach a better option when facing a valgus deformity of the osteoarthritic knee but there is no convincing evidence on the literature supporting one or another approach. The objective of this study is to compare the medial vs lateral approach for total knee replacement on valgus knee.
The implementation of a weekly hypofractionated radiation could be an advantageous alternative. The convenience of less treatment days could cause a greater adherence, decrease of costs and increase the offer of radiotherapy to major number of patients in underserved areas. The purpose of this study is to determine in women with diagnosis of initial breast cancer undergoing breast-conserving surgery the effects of the adjuvant radiotherapy using a once a week regimen, with 5 fractions in total. The study will analyze the acute toxicity of radiation, the patient's self referred quality of life, the cosmetic breast appearance, as well the oncological safety. It will also be analyzed the viability of this more contracted regimen in our community setting, regarding the patient's adherence to the treatment.
Hyperphosphatemia is related to the increase in morbidity and mortality. There is greater risk for cardiovascular disease, atherosclerotic disease, secondary hyperparathyroidism, and bone disease . The serum phosphorus level can be controlled by a combination of factors, such as: reduction of ingestion, reduction of intestinal absorption with chelating agents and increase in elimination by dialysis. The purpose of this study is to evaluate the effect of dietary intervention consisting of the restriction of industrialized foods with phosphorus additives in chronic kidney disease patients treated with hemodialysis.
