There are about 5012 clinical studies being (or have been) conducted in Mexico. 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 purpose of this study is to determine if Effective Extracorporeal Blood Flow(eEBF) has correlation with Access Blood Flow (Qa), when eEBF adjusts with Dynamic Arterial Line Pressure (DALP) in patients with Arteriovenous fistulae in hemodialysis treatment.
The purpose of this study is to determine whether a specific subtype of lymphoma responds optimally to treatment with rituximab and chemotherapy.
The purpose of this study is to determine whether sodium bicarbonate is effective in the prevention of sodium-induced nephropathy
TPMT is a key enzyme in the metabolism of thiopurines. TPMT polymorphisms have been described and are associated with a decrease activity of such enzyme. Therefore, a higher risk of developing toxicity is present in patients requiring these drugs, which are indicated in acute lymphoblastic leukemia, as well as, immunosuppressors after organ transplantation. The frequency of heterozygotes polymorphisms ranges from 3 till 12 %, in different populations. Homozygous patients have a lower frequency, estimated 1 in 300 individuals. The frequency of such polymorphisms in mestizos mexican population has not been analyzed, and we considered important to determine this frequency in healthy and patients requiring thiopurines, particularly acute lymphoblastic leukemia.
The purpose of this study is to determine whether rosuvastatin is effective as a coadjuvant drug in the integral management of abdominal sepsis acknowledged by surgery.
Purpose:Retinopathy of prematurity (ROP) continues tobe a major cause of blindness in children. Although ablation of the retina with laser or cryotherapy reduces the incidence of blindness by suppressing the neovascular phase of ROP the visual outcomes after treatment are often poor. Vascular endothelial growth factor(VEGF) has an important role in the pathogenesis of ROP and inhibition of VEGF expression in the neovascular phase might prevent destructive neovascularization in ROP. The aim of this study is to determine the safety and efficacy of intravitreal bevacizumab in the treatment of retinopathy of prematurity
The researchers aim to investigate the outcome (overall survival) of mothers who are diagnosed and/or treated for cancer during pregnancy. Furthermore they want to test the hypothesis that children who were exposed to cancer or cancer treatment (cytotoxic drugs, radiation therapy, targeted therapy,...) develop normally (neurologic and cardiologic examination).
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.
Ritonavir boosted protease inhibitor based therapy will have equivalent antiviral efficacy over 48 weeks compared to NNRTI based therapy in patients who are antiretroviral therapy naïve and initiate therapy with CD4 counts ≤ 200/mm3.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of docetaxel and ifosfamide in treating women who have metastatic breast cancer.
