Filter by:The purpose of this study is to determine whether the administration of albumin in addition to the standard care is effective in the treatment of an episode of hepatic encephalopathy in patients with cirrhosis.
The purpose of this study is to determine whether AST-120 is safe and effective in the treatment of mild hepatic encephalopathy.
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.
Non small-cell lung cancer (NSCLC) accounts 85% of all lung cancer.The development of brain metastasis diminished life expectancy to less than one year with a median survival of less than three months. In NSCLC cancer, approximately 50% of patients with locally advanced disease develop brain metastasis at some time during the natural of disease. The central nervous system constitutes the first site of recurrence in 15 to 40% of these patients. Microarrays evaluate the diagnosis, treatment and prognosis of lung cancer.There are no studies that specifically evaluate the relationship between a genetic profile of NSCLC and metastasis to the CNS, with the purpose of distinguishing a subgroup of patients that will benefit of prophylactic treatment.What is the association between a genetic profile on NSCLC and the development of CNS metastasis.Obtaining a genetic profile from the primary NSCLC tumor cells, by using microarrays, we can predict the development of CNS metastasis arise a subgroup of patients that could benefit from prophylactic cranial radiation with which their quality of life and prognosis most probably will increase.Objective:Determine the association between a genetic profile from the primary tumor cells and the development of central nervous system metastasis in patients with non small-cell lung cancer.A genetic profile from the primary tumor cells are associated with the development of central nervous system metastasis in patients with NSCLC. A clinical, prospective, analytic, open, non randomized, prognostic and observational cohort with 66 patients with NSCLC who authorize a biopsy study from February, 2008 to December, 2012, INMEGEN institute will be in charge of performing the microarrays and the computer analysis in order to obtain the different genetic profiles that will be differentially expressed related with CNS metastasis risk profiles. Patients will be followed-up by means of the external consult of lung neoplasms. The statistical analysis will be performed using tests like Student's t or Mann-Whitney's U test. A multivariate analysis of logistic regression will be performed. Global survival time will be analyzed using Kaplan-Meier's technique and the comparison between groups will be performed with log-rank test. The adjustment for potential confusors will be performed using multivariate regression analysis. For result representation, we will use tables and graphs and pertinent measures will be taken to disclose the study.
The aim of this study is to evaluate the effect of prolonged administration of albumin and midodrine on the prevention of complications (renal failure, sepsis, hemorrhage, hepatic encephalopathy and hyponatremia) in patients with cirrhosis in the waiting list for liver transplantation. One hundred and ninety four patients with cirrhosis and awaiting a liver transplantation will include in the study. Patients will be randomized to receive albumin and midodrine (treatment group) or administration of placebo (saline for albumine) and tablets with excipients without midodrine (control group). Patients will be followed-up during 12th months. In the treatment group albumin will be given at a dose of 40g every 15 days and midodrine 5mg tid, in addition with lactitol (conventional doses) and the specific treatment that patients require by cirrhosis. The group control will receive placebo in the same way than the treatment group in addition with lactitol and the specific treatment that they require by their disease. In all the patients liver and renal function test, hormones determination (renin, aldosterone, noradrenaline), and cytokines will be determined in basal conditions. All these determinations will be repeated at month 1st,3rd, 6th and 12th months. Before the inclusion in the study neuropsychological test and critical flicker test will be performed to diagnose minimum EH. These tests will be repeated at 3rd, 6th and 12th months. All the determinations will be repeated at any time that the patients develop any complication considered as an end point. In baseline conditions and at 3rd and 6th months a questionnaire of quality of life (SF36) will be performed. During a year of follow-up the number of paracentesis that patients require, the incidence of renal failure and EH and their relationship with hormonal activity and cytokine levels, free transplant survival and quality of life will be recorded.
This study is to evaluate the role of probiotics in the treatment of portal hypertension. In particular the role of probiotics on gut microbiota in liver cirrhosis patients will be studied and compared with cytokines and other substances implicated in the pathogenesis of portal hypertension. The hypothesis whether probiotics may change the prognosis of patients with portal hypertension will be studied. The hypothesis whether probiotics may halt the pathologic cascade of events leading to various complications (e.g. hepato-renal syndrome, spontaneous bacterial peritonitis, bleeding varices) will be reviewed.
The STARR network registry consists of a 4 spoke 1 hub system. Which will consist of prospective collection, recording, and regular analysis of telestroke patient consultation and care data for the purpose of quality measure assessment and improvement and benchmarking against other national and international telestroke programs.
Perinatal asphyxia-induced brain injury is one of the most common causes of morbidity and mortality in term and preterm neonates. Birth asphyxia accounts for 23% of neonatal deaths globally and survivors suffer from long term neurological disability and impairment. Although many neuroprotective strategies appeared promising in animal models, most of them were not feasible and effective in human newborns. However, hypothermia was reported not to be effective if introduced beyond and thus should be introduced within 6 hrs after birth.Applying this selection criterion naturally would deprive many patients of the opportunity of hypothermia treatment.
Pediatric patients with chronic liver disease may have Minimal Hepatic Encephalopathy(MHE)which can cause changes in behavior,intelligence and neurological function.By utilizing cognitive and developmental testing we will determine if patients have MHE. If so, we will trial 3 months of blinded placebo or Lactulose treatment followed by a washout period with no treatment. At this time patients are re-tested and then begin another three month period switching to the opposite treatment of first 3 months.Final cognitive/developmental testing will determine if Lactulose treatment has any effect on MHE.
Perinatal asphyxia-induced brain injury is one of the most common causes of morbidity and mortality in term and preterm neonates, accounting for 23% of neonatal deaths globally. Although many neuroprotective strategies appeared promising in animal models, most of them have failed clinically. Erythropoietin (EPO) is an endogenous cytokine originally identified for its role in erythropoiesis. Clinical trial has demonstrated the safety and efficacy of recombinant human erythropoietin (r-hu-EPO) in the prevention or treatment of anemia of prematurity. To date, there are no reports evaluating possible effects of EPO on neonatal HIE.
