Pilot study GLIM criteria for categorization of a malnutrition diagnosis of patients undergoing elective gastrointestinal operations: A pilot study of applicability and validation.

Objectives: The Global Leadership Initiative on Malnutrition (GLIM) was proposed to provide a common malnutrition diagnostic framework. The aims of this study were to evaluate the applicability and validity of the GLIM and use machine-learning techniques to help provide the best malnutrition-related variables/combinations to predict complications in patients undergoing gastrointestinal (GI) surgeries.

Method: This was a prospective cohort study enrolling surgical patients with GI diseases.

Ultrasonography and Other Nutrition Assessment Methods to Monitor the Nutrition Status of Critically Ill Patients.

Background: This study aims to evaluate the use of ultrasonography (US) as an instrument to assess the quadriceps muscles in patients admitted to intensive care units (ICUs), comparing the evolution of US-assessed mass muscle to other nutrition methods.

Methods: We conducted a prospective observational study of adult patients aged ≥18 years admitted to an ICU of the Hospital das Clínicas in Brazil. Quadriceps muscle measurements were performed by US, and adductor pollicis muscle thickness and arm, calf, and thigh circumferences were measured at admission and every 2 days within the first week.

Ultrasonography to assess body composition: Relevance of training.

Objective: The aim of this study was to evaluate the relevance of ultrasonography training by non-experts carrying out quadriceps muscle mass assessment.

Methods: Two non-expert evaluators were trained by two radiologists on the basic principles of ultrasonography and quadriceps muscle measurements. Afterward, they performed assessments on 30 healthy volunteers to determine interobserver agreement, considering two landmarks (two-thirds of the femoral distance, and 10 cm above the patella), which were tested by the intraclass correlation coefficient (ICC).
