Time is of the essence for reducing the long-term effects of iron deficiency
Iron deficiency is a worldwide problem, especially in developing countries and among infants and pregnant women. In infancy, iron deficiency is associated with poorer cognitive, motor, and social-emotional outcomes. In a new study scheduled for publication in The Journal of Pediatrics, researchers report on a 25-year follow-up of infants studied in Costa Rica for iron deficiency. (2013-06-28)

Supply and demand
In a study published today in Cell Metabolism, scientists at the European Molecular Biology Laboratory in Heidelberg, Germany, have discovered that a group of proteins called IRPs ensure that iron balance is kept and as such are essential for cell survival. More specifically, they found that IRPs are required for the functioning of mitochondria, the cell's energy factories. (2010-08-04)

Study finds toolkit could improve detection and management of iron deficiency in pregnancy
Iron deficiency in pregnancy is a common problem that often goes unrecognized and untreated due to a lack of knowledge of its implications and competing clinical priorities. To enhance screening and management of iron deficiency in pregnancy, a research team at Toronto's St. Michael's Hospital developed a quality improvement toolkit, called IRON MOM. The implementation of IRON MOM resulted in increased rates of ferritin testing and decreased rates of anemia at St. Michael's obstetric clinics. (2019-08-20)

Imprecise iron supplementation can spur increase in Salmonella
Individuals who do not produce enough iron are anemic, and often experience fatigue. One common remedy is for physicians to prescribe an iron infusion to their anemic patients. This makes sense, but can lead to unexpected consequences like increasing the risk of food poisons such as Salmonella. These types of poisons depend on abundant access to iron. Physicians should be attuned to this dynamic when determining the strength of iron infusions for their anemic patients. (2017-06-26)
