Description of the etiological factors behind acute moderate and severe malnutrition in children under 5 years hospitalized at two high-complexity referral centers: Case series.

Background: Acute malnutrition in children <5 years of age has a direct relationship with medical complications and mortality. We aimed to describe the etiologic factors in children with moderate and severe non-illness-related acute malnutrition who required hospitalization for treatment of malnutrition in two high-complexity hospital centers in Bogotá, Colombia.

Methods: This is a multicenter case series (December 2016 to December 2020) including patients aged 1-59 months with a weight/height indicator less than -2 SD.

Malnutrition screening tool and nutritional screening tool for classification of nutritional risk in patients with cancer upon hospital admission: Comparison of diagnostic performance using Global Leadership Initiative on malnutrition criteria as reference.

Background & Aims: Tools for screening of nutrition risk in patients with cancer are usually validated against other screening instruments. Here with the performance of Malnutrition Screening Tool (MST) and Nutritional Screening Tool (NUTRISCORE) to identify the risk of malnutrition was assessed. A full nutritional evaluation and diagnosis following criteria from the Global Leadership Initiative of Malnutrition (GLIM) was the reference standard for the classification of malnutrition.
