Nutritional screening within the GLIM procedure—Part 2: Operationalization of the concept risk of malnutrition using a modified Delphi procedure

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background and Aims Within the original GLIM procedure (2019), the step on nutritional screening was not further elaborated. A new GLIM Risk of Malnutrition Working Group has recently developed a consensus‐based conceptual definition of “risk of malnutrition.” The present study aimed to operationalize this definition.

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...
