However, feeding intolerance is heterogeneous and may reflect alterations in gastrointestinal motility, gastrointestinal perfusion and function, systemic inflammation, severity of illness, intra-abdominal pressure, metabolic disturbances, and other patient-specific factors. Reliable methods for early identification of patients at high risk of feeding intolerance remain limited.\n\nJLU\\_nutr is a prospective observational cohort study designed to systematically characterize feeding intolerance in critically ill adult patients. No study-specific therapeutic intervention is assigned, and clinical treatment and nutritional support are provided according to routine clinical practice and the judgment of the treating clinical team.\n\nWithin 24 hours after ICU admission, participants undergo a standardized multidimensional assessment. This includes collection of blood samples; gastrointestinal electrophysiological measurements; gastric antral ultrasonography, including assessment of antral size and motility; skeletal muscle ultrasonography; measurement of intra-abdominal pressure; and collection of relevant demographic, clinical, physiological, laboratory, nutritional, and severity-of-illness variables.\n\nParticipants are prospectively monitored for the development of feeding intolerance according to prespecified study criteria. Information on enteral nutrition delivery, gastrointestinal manifestations, organ support, and other relevant clinical variables is collected longitudinally during the ICU stay.\n\nThe study will investigate the incidence and clinical characteristics of feeding intolerance and examine associations between variables obtained within the first 24 hours after ICU admission and subsequent feeding intolerance. Candidate predictors include demographic and clinical characteristics, severity of illness, laboratory biomarkers, gastrointestinal electrophysiological parameters, gastric ultrasonography-derived measures, skeletal muscle ultrasonography-derived measures, intra-abdominal pressure, and other prospectively collected variables.\n\nA major objective of the study is to develop and evaluate approaches for early prediction and risk stratification of feeding intolerance using conventional clinical variables alone and in combination with multimodal measurements obtained within the first 24 hours after ICU admission. The incremental predictive value of physiological, laboratory, electrophysiological, and imaging-derived variables will also be explored.\n\nParticipants are additionally followed for clinically important short- and long-term outcomes, including duration of organ support, ICU-free days, ventilator-free days, ICU and hospital outcomes, all-cause mortality at 28, 90, and 180 days, and health-related quality of life assessed using the EQ-5D-5L.\n\nBecause this is an observational study, analyses are intended to evaluate associations, prediction, and risk stratification rather than to establish causal effects of individual exposures. The study is expected to provide a multidimensional characterization of feeding intolerance in critical illness and to generate evidence supporting future individualized nutritional assessment and intervention studies.","The study population consists of adult critically ill patients admitted to the participating intensive care unit(s).
