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.
Retrospective longitudinal cohort study with 36 HIV naïve-treatment patients, who started therapy with lopinavir/ritonavir or efavirenz (LPV/r or EFZ), follow-up of 36 months. Primary endpoint: virological success (HIV RNA <50 copies/mL) in the first six months and at the end of the study.
This clinical trial studies conservative surgery in treating patients with low-risk stage IA2 or IB1 cervical cancer. Conservative surgery is a less invasive type of surgery for early stage cervical cancer and may have fewer side effects and improve recovery.
Rolandic Epilepsy is the most common form of childhood epilepsy. It is classified as idiopathic, age-related epilepsy syndrome with benign evolution. The absence of neuropsychological impairment is part of the criteria of benignity of this epilepsy syndrome. However recently have been suggested several deficits related to attention and language. The purpose of this study was assess school performance and to investigate problems of praxis in patients with rolandic epilepsy as compared to a control group composed of normal children with age, gender and educational level equivalents.
The aim of this study is to determine whether greater rectal cancer downstaging and regression occurs when surgery is delayed to 12 weeks after completion of radiotherapy/chemotherapy compared to 6 weeks. Hypothesis: Greater downstaging and tumour regression is observed when surgery is delayed to 12 weeks after completion of CRT compared to 6 weeks.
The simple knowledge that practices healthy lifestyle are important to reduce or prevent the progression of cardiovascular diseases it is not enough for effective changes accordingly. To nutritional education be successful, needs to promote changes in eating habits and not just transmit information. This is a behavioral intervention study in 200 consecutive patients submitted to percutaneous transluminary coronary angioplasty. The participants were randomized in two groups: intervention and control. The intervention was a dialogic nutritional counseling and the control arm was a traditional nutritional counseling. All participants will undergo long-term follow-up for cardiovascular events.
To report the short term anatomic and visual acuity response after intravitreal injection of bevacizumab and ranibizumab in patients with choroidal neovascularization secondary to age-related macular degeneration.
The primary objective of this clinical trial is to demonstrate non-inferiority clinical development of pancreatic enzymes from Laboratory Bergamo (Norzyme ®) in relation to pancreatic enzymes from Solvay Pharmaceuticals (Creon ®), by comparing the average amount of lipids in the feces of 72 hours after 14 days of treatment with each drug.
The objective of this study is to assess if the association of botulinum toxin type A and kinesitherapy is superior to kinesitherapy and 0,9% saline for the functional performance in post-stroke patients. Hypothesis H(0): BT-A associated to kinesitherapy is not superior to kinesitherapy in the function of hemiparetic post-stroke patients. H(1): BT-A associated to kinesitherapy is superior to kinesitherapy in the function of hemiparetic post-stroke patients.
Investigate the therapeutic effects of the antioxidant N-acetylcysteine on early outcomes of deceased renal transplant patients.
The purpose of this study is to test the following hypotheses: 1. Enteral glutamine administration decreases in-hospital mortality in adult patients with severe thermal burn injuries. 2. Enteral glutamine administration decreases hospital-acquired blood stream infections from Gram negative organisms and length of stay in ICU and hospital for adult patients with severe thermal burn injuries. 3. Enteral glutamine administration will improve the physical function of surviving burn injured patients and reduce their cost of care. The objectives of this trial are to determine the overall treatment effect and safety of glutamine in burn patients. Specifically, the investigators want to assess the following outcomes in a sample of 1200 patients in 80 sites: 1. In patients with severe, life-threatening burn injury, what is the effect of enteral glutamine on time to discharge alive from hospital 2. In patients with severe, life-threatening burn injury, what is the effect of enteral glutamine on 6 month mortality, hospital-acquired blood stream infections from Gram negative organisms, hospital mortality, duration of stay in ICU and hospital, health-related quality of life, and health care resources?
