Filter by:GCX damage and its relationship to pharmacodynamics and pharmacokinetics of beta lactam antibiotics in critically ill Hypothesis to be tested: GCX damage impairs pharmacodynamics and pharmacokinetics of beta-lactam antibiotics in critically ill patients. There is correlation between GCX damage and insufficient beta lactam levels in patients with commonly used dosing. The aim of the study: Evaluation of relationship between GCX damage and pharmacodynamics and pharmacokinetics of beta-lactam antibiotics in critically ill. Type of the study: Observational. Subjects: Adult patients admitted to ICU with beta-lactam antibiotic therapy (meropenem or piperacillin/tazobactam empirically or based on culture results). Sample size calculation: 20 patients (expected correlation coefficient 0,6, alpha error = 0,05) will lead to power study = 0,89. Intervention: none. Data to be recorded and analyzed: Demographics, type of patients (trauma, post surgical, medical, after cardiac arrest), severity score - Apache II, SOFA, fluid balance, a presence of delirium, clinical outcome, sublingual microcirculation by SDF imaging will be recorded three times during antibiotic treatment at the time points for blood samples required for pharmacodynamics and pharmacokinetic analysis, microcirculatory data and Perfused Boundary Region.
Septic shock is associated with acquired immunoparalysis which is associated with a high risk of nosocomial acquired infection. Nosocomial candidiasis is associated with a 50% rate of mortality but is difficult to diagnose. The use of colonization indexes and risk factors on the other hand expose to unnecessary use of antifungals. The aim of the present study is to evaluate whether the host response to infection associated with candida biomarkers would help to anticipate the candidiasis onset.
- The primary aim is to document the incidence and short-term outcome of the elderly ICU patient (≥ 80 years) using a multicentre, multi national approach - The secondary aim is to investigate the properties of a simple frailty index in this cohort, and in particular if this is an instrument that can be used in resource and outcome prediction in this group - To create hypothesis for further studies, in particular on various outcome prediction
The aim of this study is to evaluate the effect of early activity and mobilisation during prolonged IMV on the composite outcome "days alive and out of hospital to day 180". The effect of the intervention on mortality, physical, cognitive and psychological function at 180 days, as well as cost-effectiveness of the intervention, will also be evaluated. The study will also explore process of care measures and baseline physiology and ICU mobility outcomes. The hypothesis is that, in ICU patients expected to require prolonged IMV, early activity and mobilisation increases the number of days alive and at home to day 180 when compared with standard care.
This study is aimed to compare the duration of standard anti fungal therapy in high risk ICU patients with a strategy driven by BetaDGlucan test result
This is a 1-year national prospective cohort study that observes the medical management of consented deceased organ donors at hospitals across Canada with a high volume of deceased donation.
Glutamine-induced recovery in intestinal barrier function by reducing bacterial translocation was demonstrated in previous studies. In this trial, intensive care unit patients with enteral feeding will receive either enteral glutamine or maltodextrin as placebo for 10 days and the effects of the intervention on intestinal permeability will be assessed.
Each year, millions of Americans are admitted to an intensive care unit (ICU). For more than half of them, ICU admission initiates a cascade of decisions about treatment and end-of-life care.This is particularly the case for patients with chronic critical illness, a life-limiting syndrome. Most (74%-82%) ICU patients who require mechanical ventilation have transient or persistent cognitive impairment that precludes them from making their own healthcare decisions. Among ICU patients, the chronically critically ill (CCI) are at highest risk for cognitive impairment and thus require a surrogate decision maker (SDM), usually a family member. SDMs for the critically ill often describe high states of psychological stress associated with the uncertainty of the patient's condition and their decision making role. The purpose of this study is to test the effectiveness of two decision support interventions for end-of-life care delivered to SDMs of CCI patients. This will be the first study to test interventions tailored to the unique needs of the SDMs of CCI patients delivered using an interactive avatar based format.
Each year, only one third of patients registered on the waiting list receive a kidney transplant. Numerous paths are being explored with the aim of reversing this shortage. The first is to increase the number of organs by developing harvesting from donors in a state of brain-death (BD) termed "expanded criteria donors" or from patients deceased from circulatory arrest. Another fundamental factor is to insure the success of the transplant by limiting the dysfunction of donor kidneys, marked by a delayed graft function (DFG). The development of techniques to insure correct perfusion of harvested organs, and the optimization of reanimation and intensive care of brain-dead donors constitute important factors in DGF reduction. Therapeutic Hypothermia could to be an attractive care strategy for BD patients.
Delirium is a syndrome of acute brain dysfunction involving attention and cognition that affects up to half of older hospitalized patients and 50%-75% of critically ill ICU patients, such that millions of patients worldwide experience this acute threat to their health and well being every year. One-third to half of critical illness survivors struggle with a dementia-like disorder similar in severity to moderate-to-severe traumatic brain injury or Alzheimer's Disease, and the only proven risk factor that is potentially modifiable is delirium in the ICU. Despite the frequency and impact of delirium in the ICU, little is known regarding the biological mechanisms that lead to this form of organ dysfunction during critical illness. A widely held hypothesis proposes that inflammation is regulated by the cholinergic system, and that this interaction plays a pivotal role whether delirium developments in the setting of acute illness. Acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) are enzymes that hydrolyze the neurotransmitter acetylcholine. Changes in the activity of these enzymes, which can be measured in whole blood, reflect altered regulation of circulating acetylcholine. AChE and BuChE activities have promise as both predictors of delirium (when found to be low at admission) and biomarkers of delirium (when low during serial measurement). Neither of these biomarkers, however, have been studied in the ICU setting where delirium risk is the highest. The current investigation, therefore will be the first to determine the validity of circulating AChE and BuChE activities as biomarkers of delirium during critical illness and subsequent cognitive impairment after discharge. This study will measure whole blood AChE and butyrylcholinesterase BuChE activities within the framework of the ICU Delirium and Cognitive Impairment Study Group's ongoing clinical trials in critically ill patients.
