Cognitive impairment caused by compromised hepatic ketogenesis is prevented by endurance exercise.

Extensive research has demonstrated endurance exercise to be neuroprotective. Whether these neuroprotective benefits are mediated, in part, by hepatic ketone production remains unclear. To investigate the role of hepatic ketone production on brain health during exercise, healthy 6-month-old female rats underwent viral knockdown of the rate-limiting enzyme in the liver that catalyses the first reaction in ketogenesis: 3-hydroxymethylglutaryl-CoA synthase 2 (HMGCS2).

Hepatocellular RECK as a Critical Regulator of Metabolic Dysfunction-associated Steatohepatitis Development.

Background & Aims: Reversion-inducing cysteine-rich protein with Kazal motifs (RECK) is an extracellular matrix regulator with anti-fibrotic effects. However, its expression and role in metabolic dysfunction-associated steatohepatitis (MASH) and hepatic fibrosis are poorly understood.

Methods: We generated a novel transgenic mouse model with RECK overexpression specifically in hepatocytes to investigate its role in Western diet (WD)-induced liver disease.

A Retrospective Study Evaluating Guideline Adherence of Neonatal Parenteral Nutrition in a Belgian Neonatal Intensive Care Unit.

Introduction Clinical nutrition for preterm and critically ill neonates remains a challenge. Preterms are often hemodynamically and metabolically compromised, which limits infusion volumes of nutrients and hinders achieving recommended nutrient intakes. While guidelines provide recommended ranges for parenteral nutrition (PN) intakes, they generally recommend enteral nutrition as soon as possible.

Relationship between serum β-hydroxybutyrate and hepatic fatty acid oxidation in individuals with obesity and NAFLD.

Nonalcoholic fatty liver disease (NAFLD) is characterized by excess lipid accumulation that can progress to inflammation (nonalcoholic steatohepatitis, NASH), and fibrosis. Serum β-hydroxybutyrate (β-HB), a product of the ketogenic pathway, is commonly used as a surrogate marker for hepatic fatty acid oxidation (FAO). However, it remains uncertain whether this relationship holds true in the context of NAFLD in humans.

The Use of Standardized Solutions Instead of Individualized Prescriptions for Parenteral Nutrition on the Neonatal Intensive Care Unit in UZ Brussel: A Feasibility Study.

For parenteral nutrition (PN) of newborns, the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) 2018 guidelines recommend standardized solutions over individual PN (IPN) solutions for most patients. This retrospective study assessed if a shift from IPN to standardized PN was feasible at the UZ Brussel. Using prescription data of 145 neonates, we calculated the nutrient provision for IPN and for standardized PN of the same volumes.
