There are about 1933 clinical studies being (or have been) conducted in Colombia. 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.
This is a prospective, multicentre, randomized clinical trial comparing two different neo-adjuvant radiation-based strategies prior to intended surgery for locally advanced adenocarcinoma of the rectum. This trial may establish the investigational therapy to be superior to, or at least not inferior to conventional treatment.
This is a Phase 4, observational, open study in patients whom their doctor for clinical practice prescribes levamlodipine. No medication was provided by the sponsor. The planned observation time is 8 weeks. The 8 weeks of observation involves an evaluation of baseline followed by information gathered from the assessment visits at week 4 and week 8, or clinical practice.
This is a Phase 4, observational, open study in patients who their doctor has prescribe METPURE XL (S (-)metoprolol succinate)by clinical practice. No medication was provided by the sponsor. The planned observation time is 8 weeks. The 8 weeks of observation involves an evaluation of baseline followed by information gathered from the assessment visits at week 4 and week 8.
The purpose of the Multi-National Gilenya Pregnancy Exposure Registry in Multiple Sclerosis (MS) is to continuously monitor, evaluate, and assess for major and minor teratogenic effects in the offspring of women exposed to fingolimod before (up to 8 weeks before last menstrual period (LMP)) and during pregnancy in routine clinical practice. The overall aim is to collect and evaluate data on maternal, fetal, and infant outcomes and compare it with reference populations.
The purpose of this study is to determine the efficacy of dexamethasone for treatment of HELLP I (hemolysis, elevated liver enzymes and low platelet count) syndrome.
The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation.
After performing VATS pulmonary wedge resections, a chest tube is routinely left in the pleural cavity to drain possible air leaks and fluid accumulations. Chest tubes after VATS pulmonary wedge resections are left in place a minimum of 1 day. However, this practice has no scientific foundations. The investigators believe it is possible to avoid the placement of a chest tube after this procedure in a great amount of patients. This is a randomized controlled clinical trial with analysis blinding in which the investigators want to compare the outcomes between installing a chest tube or not after VATS pulmonary wedge resections. The investigators will include consecutively patients with interstitial lung disease or indeterminate pulmonary nodules undergoing this procedure, at the participating institutions. The investigators calculated a sample size of 50 subjects in each group using pneumothorax < 10% data from Luckraz et al and to determine a difference of hospital stay of 2 versus 1 day; DS(1.5), power = 0.9 and alpha = 0.05.
The purpose of this study is to determine whether hypochlorous acid is an effective antiseptic agent to prevent surgical site infection.
Background: Existing criteria for AS/SpA such as mod. New York, ESSG, or Amor criteria for classification and/or diagnosis of spondyloarthritis have limitations when applied to early disease. Moreover, MRI is not part of any of the established criteria and the precise role of MRI in early axial disease has not been fully defined yet. Even less is known about sacroiliac (SI) changes in SpA patients with peripheral symptoms. A pilot study using data from 'paper patients' led to new candidate criteria for early spondyloarthritis. Subsequently, the members of the ASAS International Working Group decided to conduct a prospective multi-centre study to evaluate (validate) the new candidate criteria, and to assess their performance as diagnostic criteria. Aims of the study: 1. To evaluate the new candidate criteria for axial SpA in a multi-centre setting. 2. To assess the potential role of the new candidate criteria to be used as diagnostic criteria. To accomplish this, inclusion of consecutive and undiagnosed patients is mandatory as are longer periods of follow-up . 3. To compare criteria encompassing the whole group of SpA such as ESSG and Amor criteria against criteria which are tailored to either predominant axial disease or predominant peripheral disease. To accomplish this, both patients with predominant axial disease (back pain) but also patient with predominant peripheral disease (arthritis/enthesitis) will be included.
The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Pompe disease population. - To evaluate the long-term effectiveness of alglucosidase alfa.
