Controversies in NEN: An ENETS position statement on nutritional support in neuroendocrine neoplasms

Journal of Neuroendocrinology, Volume 37, Issue 12, December 2025.
Abstract Neuroendocrine neoplasms (NEN) themselves and also their treatment may cause malnutrition, inducing changes in physiological behaviour and eventually leading to increased rates of morbidity and mortality. Malnutrition is a common, under‐recognised and under‐treated condition in patients with NEN, and there are limited data available on the ...

Active B12: A Rapid, Automated Assay for Holotranscobalamin on the Abbott AxSYM Analyzer [PDF]

Clinical Chemistry, 2008
AbstractBackground: Conventional tests for vitamin B12 deficiency measure total serum vitamin B12, whereas only that portion of vitamin B12 carried by transcobalamin (holotranscobalamin) is metabolically active. Measurement of holotranscobalamin (holoTC) may be more diagnostically accurate for detecting B12 deficiency that requires therapy.
