RESUMEN
Malnutrition is a common complication in patients with malignant tumors, which affects the clinical outcome of cancer patients. Accurate identification of malnutrition is the premise of nutritional intervention and treatment, but uniform diagnostic criteria for malnutrition are currently lacking. With the official release of the Global Leadership Initiative on Malnutrition (GLIM) initiated by global nutrition experts in 2018, a large cohort of studies have been carried out. In this article, the specific content and controversies of the GLIM criteria, its accuracy validation and clinical predictive value in patients with malignant tumors were mainly reviewed, aiming to provide reference for subsequent research and clinical application of malignant tumor-related malnutrition.
RESUMEN
Malnutrition is closely related to clinical outcomes and accurate evaluation of nutritional status is the cornerstone of nutritional therapy. However, consistent diagnostic criteria for malnutrition have been absent for quite a long period. The Global Leadership Initiative on Malnutrition (GLIM) criteria were introduced in September 2018 and served as a consensus-based evaluation tool. As per GLIM criteria, evaluation of malnutrition should follow a two-step approach with nutritional screening as the first step and then malnutrition diagnosis assessment and severity grading based on etiologic as well as phenotypic metrics. Since debut, GLIM criteria have been applied in different countries, healthcare settings and populations, showing good accuracy and prognostic value for outcomes such as complications and survival. However, most of the studies are retrospective in nature and high-quality prospective studies are needed to better validate GLIM criteria. The way to steer nutritional interventions based on GLIM criteria is also worth future investigation.
RESUMEN
Objective:To analyze the prevalence of malnutrition in stable-phase elderly patients with chronic obstructive pulmonary disease (COPD) using the Global Leadership Initiative on Malnutrition (GLIM) criteria.Methods:Using cross-sectional survey, 60 elderly patients with COPD in stable phase were investigated, with 72 elderly patients without COPD in the same age group selected as controls. Differences in basic characteristics, anthropometric indicators, hematology indicators and body composition were compared between the two groups. According to the GLIM diagnostic criteria for malnutrition, the first step is nutritional risk screening, the second step is to diagnose malnutrition, and the third step is to determine severe malnutrition. The prevalence of malnutrition and severe malnutrition were investigated.Results:The levels of total protein, albumin, creatinine, and lymphocyte percentage in the elderly stable COPD group were significantly lower than those in the control group. The nutritional risk and the prevalence of malnutrition in elderly COPD patients were significantly higher than those in the control group, and the prevalence of severe malnutrition was higher .Conclusions:Elderly stable COPD patients of different age groups have a higher nutritional risk. The onset age of malnutrition is younger than that of non-COPD patients and early intervention is required.
RESUMEN
In the 42 nd and 44 th workshops of CSPEN-nutritional risk-undernutrition-support-outcome-cost effectiveness ratio (NUSOC) multi-center database collaboration group, Jens Kondrup and Henrik Rasmussen described again the application of NRS 2002, the evidence-based basis of NRS 2002 development and the methodology for prospective validation of clinical effectiveness. There is no gold standard for validation. They both considered that malnutrition could be identified as a score of 3 or more for impaired nutritional status in NRS 2002. Although NRS 2002 is simple and easy to be applied, it is not comprehensive enough for malnutrition diagnosis. ASPEN and ESPEN on-line published the Global Leadership (nutritional) Initiative on Malnutrition(GLIM)diagnosis criteria in September 2018. With the gradual implementation of medicare payment based on diagnosis related groups(DRG)in China, the nutritional risk and the malnutrition diagnosis with Chinese version of ICD-10 (2016) code should be recorded in the first page of the medical records. In this terminology interpretations, the terms of nutritional risk screening(NRS 2002.01.016)and malnutrition diagnosis (GLIM-phenotypic criteria 01.028, etiologic criteria 01.029) published in Parenteral and Enteral Nutrition Terminology 2019 are discussed based on the reports given by Kondrup and Rasmussen in Beijing and Zhengzhou.
