Current infusion practices-nocturnal home parenteral nutrition (NHPN)-may induce circadian misalignment (chronodisruption). This misalignment can negatively impact metabolic function, sleep quality, and overall quality of life for both patients and caregivers. Synchronising MNT administration with circadian rhythms may improve metabolic balance, sleep, and patient well-being.\n\nHypothesis: The timing of the administration of Medical Nutritional Therapy via nocturnal home parenteral nutrition (NHPN) in outpatients may induce chronodisruption in biological rhythms (clock genes).
