The breath print represents a novel biomarker of malnutrition in pulmonary arterial hypertension: A proof of concept study.

Background: The breath print is a quantitative measurement of molecules in exhaled breath and represents a new frontier for biomarker identification. It is unknown whether this state-of-the-art, noninvasive method can detect malnutrition. We hypothesize that individuals with malnutrition will present with a distinguishable breath print.

Correlation of New Criteria for Malnutrition Assessment in Hospitalized Patients: AND-ASPEN Versus SGA.

Identifying malnutrition in the hospitalized patient is important as it correlates with increased morbidity. The Subjective Global Assessment (SGA) is recognized in the literature as a standardized and validated method for diagnosing malnutrition. The Academy of Nutrition and Dietetics (AND) and the American Society for Parenteral and Enteral Nutrition (ASPEN) developed a comprehensive method (AND-ASPEN criteria) for diagnosing malnutrition that has yet to be validated.

Underrecognition of Malnutrition in Advanced Cancer: The Role of the Dietitian and Clinical Practice Variations.

Introduction: Malnutrition (MN) often goes unrecognized due to ineffective screening techniques. Published standards for multidisciplinary care exist but no consensus on best nutritional assessment for hospitalized patients. Malnutrition is common in cancer and adversely affects clinical outcomes.
