Purpose Of Review: Iron deficiency is a common condition affecting approximately 50% of patients with heart failure. The purpose of this review is to explore the impact of iron deficiency on patients' quality of life and outcomes. Moreover, how intravenous replacement, even in the absence of anemia, can improve these outcomes.
Recent Findings: The role of iron deficiency anemia has long been a part of assessing reversible and treatable contributors to patients' symptoms in heart failure. Recent studies have demonstrated how vital identifying not only anemic patients but those who are iron deficient without anemia, may allow us to impact their quality of life by several different measures. The latter appears to be the case not only for reduced ejection fraction but also impacts patients with preserved ejection fraction who have very few other modalities which improve symptoms.
Summary: Iron deficiency in heart failure is common, and with improvements in diagnosis and management, it has led to a better understanding of the importance of iron deficiency in cardiac failure and function.

The aim of this study was to assess the effect of nutrition education and counseling using health belief health model constructs along with iron-folic acid supplementation on hemoglobin level and adherence to IFAs during pregnancy. The study was a three-month quasi-experimental study design in Butajira town, Ethiopia. Community-based nutrition education and counseling sessions using the Health belief model, and IFAS for six weeks were given to the pregnant women.

Fluorescent nanosensors operating have shown recent success toward informing basic plant biology and agricultural applications. We developed near-infrared (NIR) fluorescent nanosensors using the Corona Phase Molecular Recognition (CoPhMoRe) technique that distinguish Fe(II) and Fe(III) species with limit of detection as low as 10 nM. An anionic poly(p-phenyleneethynylene) (PPE) polyelectrolyte wrapped single-walled carbon nanotube (SWNT) shows up to 200% turn-on and 85% turn-off responses to Fe(II) and Fe(III), respectively, allowing spatial and temporal analysis of iron uptake in both foliar and root-to-shoot pathways.

Iron deficiency anaemia (IDA) poses a significant health challenge during pregnancy, affecting up to 30% of pregnant women in the UK. It has been linked to poor health outcomes for the mother, foetus, and the infant. Despite its prevalence and impact, current diagnostic and therapeutic approaches are limited.
