Filter by:This is a research study to determine if a particular method of providing nutrition improves the clinical outcomes of patients in the intensive care unit (ICU) who have undergone abdominal surgery and would require nutrition delivered via the bloodstream (called total parenteral nutrition or TPN). The nutrition method we are testing is a structured nutrition delivery plan that involves tube feeding, oral nutrition supplements, and the use of a device (called an indirect calorimeter or IC) to measure calorie needs. This study will also use two devices to measure fat and muscle mass to examine changes during hospitalization. Subjects will be followed throughout hospitalization where nutrition status and fat and muscle mass will be closely monitored. Study activities will begin within 72 hours of a patient's abdominal surgery. TPN (total parenteral nutrition, a method of feeding that bypasses the usual process of eating and digestion) will be started, a non-invasive method of assessing calorie needs (indirect calorimetry (IC)) will be started, a urine sample will be collected to help assist in protein needs, and fat/muscle mass will be measured using bioelectrical impedance analysis (BIA), and an ultrasound. This is a minimal risk study and all products/devices used are non-invasive and FDA-approved. Indirect calorimetry and urine sample collection will be conducted every 3 days during the stay in the Intensive Care Unit - ICU, then every 5 days until hospital discharge. BIA and muscle ultrasound will be conducted every 7 days during ICU stay, then every 14 days until hospital discharge.
The Vendys II, an FDA-approved device, uses finger digital thermal monitoring (DTM) after a period of blood flow restriction to evaluate vascular health. This study will evaluate the feasibility of using this device to measure the Vascular Reactivity Index (VRI) in children and adolescents/young adults (AYA) undergoing hematopoietic cell transplantation (HCT).
Fragility, geriatric concept recent identification is defined by simple physical indicators. The literature suggests that it is related to the risk of hospitalization, falls, institutionalization and death. Some studies have shown a link with heart disease, including heart failure. The link with the TIA (transient ischemic attack) has however never been studied. A fortiori, the impact of the fragility of the risk of recurrent stroke after TIA is unknown. Several questions need to be asked: Among older patients hospitalized for TIA, what proportion of those completing the criteria of frailty? In this same population, is there a correlation between fragility and scores ABCD2 score itself predictive of the risk of subsequent ischemic stroke? In other words, fragile subjects who have a TIA Have a higher risk of ischemic stroke (which could cause a strengthening of prevention measures)?
