This study is designed to determine if the following are true. When protein requirements exceed metabolic requirements, blood urea nitrogen(BUN) levels will rise. Elevated BUN levels in the absence of renal failure, hepatic failure, or GI bleeding, will be correlated with improved nitrogen balance and inversely correlated with infection rates, days of mechanical ventilation, ICU days, and total hospital days.
The purpose of this study is threefold. First, to determine if a correlation exists between BUN and nitrogen balance in the context of hyperproteic nutrition administration. Creatinine clearance will also be followed to determine if there is any harmful effect to the kidney secondary to an elevated BUN. Secondly, to determine if there is a difference in hospital acquired infection rate, ventilator days, ICU days, and hospital stay between the current nutrition standard at Penn State Hershey Medical Center and a hyperproteic nutrition protocol. Thirdly, to determine the accuracy of at least three calculated creatinine clearance formulae when compared to a measured creatinine clearance.

The aim of this study is to compare two nutritional regimes in critically ill patients. Patients will be randomized to standard care (25 kcal per kg) or to hypocaloric nutrition (15 kcal p...
The objective of this study is to compare the difference in daily protein intake of critically ill patients in two standardized enteral nutrition formulas (20% versus 33% percent) with the...
The purpose of this study is to determine if naso-jejunal feeding (feeding beyond the stomach) improves the efficacy of enteral feeding (feeding into the gut) in critically ill patients. ...
Mechanical ventilation has become one of the most important supportive treatment methods to save the life of critically ill children over time. Ventilator-associated pneumonia (VAP) is a c...
Enteral nutrition in critically ill patients undergoing vasoactive support due to hemodynamic instability is controversial. Hypothesis: enteral nutrition delivered in such patients can be ...
There are several methods of enteral nutrition (EN) administration, including continuous, cyclic, intermittent, and bolus techniques, which can be used either alone or in combination. Continuous feedi...
Enteral feeding via feeding tube (FT) provides essential nutrition support to critically ill patients or those who cannot intake adequate nutrition via the oral route. Unfortunately, 1%-2% of FTs plac...
The use of enteral nutrition (EN) in the intensive care unit (ICU) is subjected to frequent feeding interruption (FI). The prevalence and duration of causes for EN FI was investigated.
Critically ill people are at increased risk of malnutrition. Acute and chronic illness, trauma and inflammation induce stress-related catabolism, and drug-induced adverse effects may reduce appetite o...
Necrotizing enterocolitis (NEC) is one of the most significant causes of morbidity and mortality among premature infants. The exact cause is considered multifactorial and related to gastrointestinal i...
Nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route). This includes oral feeding, sip feeding, and tube feeding using nasogastric, gastrostomy, and jejunostomy tubes.
The administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered by a route other than the alimentary canal (e.g., intravenously, subcutaneously).
The at-home administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered via a route other than the alimentary canal (e.g., intravenously, subcutaneously).
The science of breeding, feeding and care of domestic animals; includes housing and nutrition.
Liquid formulations for the nutrition of INFANTS, useful for those with special needs or MILK HYPERSENSITIVITY or those whose mothers are unable to breastfeed (BREAST FEEDING).
Chronic kidney disease (CKD), also known as chronic renal disease, is a progressive loss in renal function over a period of months or years. The symptoms of worsening kidney function are non-specific, and might include feeling generally unwell and experi...
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
