Patients with a positive undernutrition screening score stay in hospital 1.4 days longer, with more associated complications and costs. A paper elsewhere in this journal describes the implementation of a novel in-hospital meal service resulting in improved protein and energy intake.

Nutrition and the circadian timing system.

Life on earth has evolved under the daily rhythm of light and dark. Consequently, most creatures experience a daily rhythm in food availability. In this review, we first introduce the mammalian circadian timing system, consisting of a central clock in the suprachiasmatic nucleus (SCN) and peripheral clocks in various metabolic tissues including liver, pancreas, and intestine.

"MY PKU": increasing self-management in patients with phenylketonuria. A randomized controlled trial.

Background: Phenylketonuria (PKU) is an autosomal recessive disorder of phenylalanine metabolism. The inability to convert phenylalanine (Phe) into tyrosine causes Phe to accumulate in the body. Adherence to a protein restricted diet, resulting in reduced Phe levels, is essential to prevent cognitive decline.
