Iron is an essential element for all living organisms, but produces toxic oxidants. Thus, iron homeostasis is tightly regulated in mammals. Hepcidin-25 (hepcidin) has emerged as a molecule that regulates iron metabolism. Binding of hepcidin to its receptor, ferroportin, inhibits intestinal iron absorption and iron efflux from hepatocytes and macrophages. Decreased hepcidin enhances iron absorption and efflux. Hepcidin could be predictive of iron status and the response to iron supplementation or erythropoietin-stimulating agents...

PURPOSE: Serum level of 25-hydroxyvitamin D (25-OHD) is considered as the most appropriate marker of vitamin D status. However, only a few studies have investigated the relationship between 25-OHD and parathyroid hormone (PTH) in children. To this end, this study was aimed at evaluating the lowest 25-OHD level that suppresses the production of parathyroid hormone in children. METHODS: A retrospective record review was performed for children aged 0.2 to 18 years (n=193; 106 boys and 87 girls) who underwent simultaneous measurements of serum 25-OHD and PTH levels between January 2010 and June 2014...

Vitamin A supplementation (VAS) programs targeted at children aged 6-59 months are implemented in many countries. By improving immune function, vitamin A (VA) reduces mortality associated with measles, diarrhea, and other illnesses. There is currently a debate regarding the relevance of VAS, but amidst the debate, researchers acknowledge that the majority of nationally-representative data on VA status is outdated. To address this data gap and contribute to the debate, we examined data from 82 countries implementing VAS programs, identified other VA programs, and assessed the recentness of national VA deficiency (VAD) data...
