Purpose: This study aimed to develop a comprehensive practical guide for enteral nutrition (EN) designed to enhance patient safety and reduce complications in Korea. Under the leadership of the Korean Society for Parenteral and Enteral Nutrition (KSPEN), the initiative sought to standardize EN procedures, improve decision-making, and promote effective multidisciplinary communication. Methods: The KSPEN EN committee identified key questions related to EN practices and organized them into seven sections such as prescribing, delivery route selection, formula preparation, administration, and quality management. Twenty-one experts, selected based on their expertise, conducted a thorough literature review to formulate evidence-based recommendations. Drafts underwent peer review both within and across disciplines, with final revisions completed by the KSPEN Guideline Committee. The guide, which will be published in three installments, addresses critical elements of EN therapy and safety protocols. Results: The practical guide recommends that EN orders include detailed elements and advocates the use of electronic medical records for communication. Standardized prescription forms and supplementary safety measures are outlined. Review frequency is adjusted according to patient condition—daily for critically ill or unstable patients and as dictated by institutional protocols for stable patients. Evidence indicates that adherence to these protocols reduces mortality, complications, and prescription errors. Conclusion The KSPEN practical guide offers a robust framework for the safe delivery of EN tailored to Korea’s healthcare context. It emphasizes standardized protocols and interdisciplinary collaboration to improve nutritional outcomes, patient safety, and operational efficiency. Rigorous implementation and monitoring of adherence are critical for its success.

Purpose: This study aimed to investigate whether the serum extracellular newly identified receptor for advanced glycation end products binding protein (EN-RAGE) and the soluble form of RAGE (sRAGE) measured at diagnosis are associated with all-cause mortality in patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). Materials and Methods: Serum EN-RAGE and sRAGE were measured in 75 immunosuppressive drug-naïve MPA and GPA patients using an immunoassay, with their clinical and laboratory data reviewed. The optimal cut-off point of EN-RAGE and sRAGE was calculated by finding the threshold with the maximum sum of sensitivity and specificity. In addition, the least absolute shrinkage and selection operator regression was adopted to select variables included in the multivariable Cox proportional hazards (PH) regression model. Results: The median age of the patients was 67.0 years, and 34% were male. Neither serum EN-RAGE nor sRAGE at diagnosis was correlated with the Birmingham Vasculitis Activity Score. Furthermore, no correlation was observed between serum EN-RAGE and sRAGE. Deceased patients had significantly lower serum EN-RAGE and higher serum sRAGE at diagnosis compared to surviving patients. Patients with serum EN-RAGE at diagnosis ≤84.37 ng/mL and serum sRAGE at diagnosis ≥1.82 ng/mL showed significantly lower survival probabilities compared to those without. In multivariable Cox PH regression model, only serum sRAGE at diagnosis ≥1.82 ng/mL, rather than serum EN-RAGE at diagnosis ≤84.37 ng/mL, was independently associated with all-cause mortality (hazard ratio 7.094). Conclusion This study is the first to demonstrate that serum sRAGE at diagnosis may independently predict all-cause mortality during follow-up in patients with MPA and GPA.
