Association of modified NUTRIC score with 28-day mortality in critically ill patients.
For patients in the intensive care unit (ICU), nutritional risk assessment is often difficult. Traditional scoring systems cannot be used for patients who are sedated or unconscious since they are unable to provide information on their history of food intake and weight loss. We aim to validate the NUTRIC (NUTrition RIsk in Critically ill) score, an ICU-specific nutrition risk assessment tool in Asian patients. ⋯ In a mixed Asian ICU population, mNUTRIC score is independently associated with 28-day mortality. Increased nutritional adequacy may reduce the 28-day mortality in patients with a high mNUTRIC score.

Severe obesity in children and adolescents is now a serious global health concern. Accurate measurements of resting energy expenditure (REE) is a key foundation for successful obesity treatment. Clinical dietitians rely heavily on measured or calculated REE to tailor dietary interventions. Indirect calorimetry (IC) is the gold standard for measuring REE. However, predictive resting energy expenditure (PREE) equations are commonly used when IC is unavailable due to cost or practicality. PREE equations differ based on variables such as age, gender, weight, and height and selecting the most accurate PREE for an individual is crucial to avoid over or underestimation of energy requirements. Published studies investigating the accuracy of PREE equations in obese children and adolescents have reported inconsistent findings, which likely result from heterogeneity in the patient populations studied. Accordingly, this study aimed to (a) assess the accuracy of the published PREE equations in a group of severely obese (SO) adolescents using IC measurement, and (b) determine if there is a BMI threshold at which the PREE equations become less accurate. ⋯ In adolescents with severe obesity, the Mifflin equation best predicts REE. This should be the equation applied when using PREE to optimize nutritional care in this population.

Geriatric nutritional risk index correlates with length of hospital stay and inflammatory markers in older inpatients.
Malnutrition is a prevalent condition in older inpatients and has been shown to increase morbidity and direct medical costs. A number of established tools to assess malnutrition are available but malnourished patients rarely receive adequate nutritional assessment and treatment. The medical and economic consequences of malnutrition in hospitalized patients are therefore often underestimated. This study investigates whether the Geriatric Nutritional Risk Index (GNRI) predicts hospital mortality, correlates with length of hospital stay (LOS) and inflammatory markers in older inpatients. ⋯ The GNRI correlates well with indicators of inflammation and the length of hospital stay. The routine implementation of the GNRI for the nutritional assessment of older patients could have a significant medical and socio-economic impact.
