Filter by:The purpose of this study is to determine whether Rosiglitazone,decreases the ADMA concentration and thereby increases the arginine/ADMA ratio of critically ill patients.
The identification of patients with potential early organ failure is the key in preventing admission or readmission to a critical care facility. The primary goal of the Outreach Project is to ensure that all patients with threatening organ failure receive appropriate and timely treatment in a suitable area; avoid admission to the intensive care unit (ICU); and share ICU skills by a partnership in education. The objectives of the study are to determine whether the introduction of an intensive care unit based medical emergency team, responding to hospital-wide preset criteria of physiologic instability, will decrease the number of predefined serious adverse events (SAEs) and to investigate the effects on quality of life and costs in a general surgery population. Study Hypothesis: The Outreach intervention will decrease the number of predefined serious adverse events; increase quality of life; and decrease costs.
The purpose of this research study is to gather clinical and biologic information from severely injured patients to better understand and characterize the host response to injury and inflammation across several domains. This information may improve outcome prediction, improve clinical treatment of injured patients, and permit the construction of non-biologic computerized models of illness that can be utilized to represent the host response in future research efforts. This study is designed as the calibration of a mathematical model of this response with predictive capabilities. The central hypothesis governing this study is that adaptive immune elements are crucial to determining the outcome of complex inflammatory scenarios. We propose to test these hypotheses in the following interrelated Specific Aims: Specific Aim 1: To develop a robust mathematical model describing trauma/hemorrhage-induced inflammation in humans, its pathologic consequences, and possible therapies. Specific Aim 2: To translate the mathematical model to humans and create software aimed at individualized clinical decision-making. Specific Aim 3: To determine the prevalence of an IL-1 receptor-associated kinase (IRAK-1) variant haplotype located on the X-chromosome in an injured population, and to characterize differences in the pro-inflammatory response across gender, relative to the IRAK-1 haplotype. Specific Aim 4: To determine if increased arginase activity previously observed in isolated peripheral blood mononuclear cells of trauma patients is a consequence of the presence of contaminating activated granulocytes or a particular subset of an arginase positive monocyte subset.
The purpose of this study is to determine the safety and operative efficacy of intermittent hemodialysis without anticoagulation with saline flushes or Nephral 400ST in patients at high risk of bleeding
The hypothesis of this study is that bioenergetic failure in human sepsis, related to endocrine, metabolic and mitochondrial dysfunction, is a major determinant of defective host immune responses, increasing disease severity and risk of death. The objectives of this study are to examine the relationship between the severity of illness, and temporal changes in the activity of endocrine, metabolic and bioenergetic pathways, and consequent immune dysfunction in critically ill patients with sepsis and multiple organ failure in the Intensive Care Unit.
OBJECTIVES: I. Determine the total energy expenditure in term and preterm infants in both well and ill states using the doubly labeled water method.
