Filter by:The purpose of this study is to determine whether storage time affects how human body responds to autologous blood transfusion. An autologous blood transfusion is when a person donates blood and then receives that same blood back in the transfusion. We also want to find out if in this situation inhaled nitric oxide can help to prevent the potential reduction of vasodilation capacity. Vasodilation capacity is the ability of the blood vessel to widen when needed.
Hypotheses: 1. In the acute phase of early illness, tissue oxygen saturation and vascular occlusion test (VOT) are important adjuncts in differentiating severe critical illness requiring ICU admission from patients benefiting from less aggressive therapies (non-ICU admission). 2. An early feature of severe sepsis is abnormal microcirculatory vasoreactivity. 3. Microvascular reactivity can be measured by means of vascular occlusion test (VOT) using non-invasive near infrared spectroscopy (NIRS) to measure tissue Oxygen saturation (StO2). 4. Microvascular reactivity is significantly deranged in patients with early severe sepsis and is quantifiably different from non-septic critically ill patients. 5. Other measures of microcirculatory perfusion ie. sublingual orthogonal polarization spectral (OPS) video microscopy, are abnormal and will directionally correlate with VOT and StO2 in severe sepsis 6. In severely septic patients response to therapy can be assessed by VOT and StO2 monitoring and will correlate with prognosis. 7. A management protocol incorporating VOT and StO2 monitoring in addition to conventional hemodynamic and biochemical parameters as a guide to therapy will result in improved outcomes in severely septic patients. This project will investigate the use of a non-invasive near infrared light (NIR) device in conjunction with brief arm compression to measure the microcirculation in critically ill patients. It is know that in patients with overwhelming infections, their blood vessels do not respond normally and the NIR device can help measure how abnormal their blood vessels are. This type of testing is non-invasive and can be performed repeatedly without harm to the patient and may provide an earlier way to determine whether they have overwhelming sepsis and also may help to optimize the treatments they receive and better tailor their treatments to the degree of blood vessel abnormalities that are found. If our hypotheses are correct, this simple non-invasive test could provide a very rapid means of assessing patients that could be done more safely and quickly than some of the current methods. This would have an important effect to enhance patient safety and improve outcomes in such critically ill patients.
The objective of this randomized, double-blind, placebo-controlled, parallel-design clinical trial is to investigate the potential antioxidant benefits of a cranberry beverage. The investigators hypothesize the chronic consumption of this beverage will improve indices of oxidative stress, inflammation, endothelial function, and glucoregulation. The investigators also hypothesize that these benefits will be particularly evident following an oral glucose tolerance test.
The objective of this randomized, double-blinded, placebo-controlled, parallel trial is to determine whether consuming avenanthramide-enriched oats daily for 8 weeks on can improve biomarkers of inflammation in older, obese adults.
Chronic inflammation in dialysis patients is linked to cardiovascular mortality and clinical signs and symptoms, like the impaired response to erythropoiesis-stimulating agents (ESAs). This study aims to demonstrate that high cut-off hemodialysis is effective in reducing chronic inflammation and thereby improving response to ESAs.
The primary aim of this study will be to evaluate the effects of Lyprinol® supplementation on airway inflammation and the bronchoconstrictor response to dry air hyperpnea in individuals with asthma. The investigators hypothesize that Lyprinol® supplementation, compared to placebo, will significantly attenuate airway inflammation and hyperpnea-induced bronchoconstriction in asthmatic individuals.
Childhood obesity is increasing at a fast pace, together with its complications. The aim of the present study is to assess several candidate triggering agents, mechanisms and intermediate phenotypes of atherosclerosis during the post-prandial phase in the obese insulin-resistant child/adolescent.
The primary objective of this study is to compare the incidence of postoperative hypergranulation tissue formation after gastrostomy tube placement among children randomized to one of three treatments, in addition to measuring tube dislodgements and rates of resource utilization for complications.
The purpose of the study is to investigate whether different doses of caffeinated coffee consumption has acute effects on subjective appetite feelings, energy intake and biochemical markers related to appetite, inflammation and glucose metabolism compared to water consumption in normal weight and overweight/obese participants.
The purpose of this study is to evaluate the serum concentrations of antoxidant vitamines A, C, E, inflammatory cytokines and middle-large toxins in patients treated with online hemodiafiltration, standard HFR and SUPRA-HFR.
