The iron endowment at birth depends, in large part, on the newborn's birth weight and gestational age. These are determined by many factors, some of which are maternal characteristics, including the following: maternal iron stores at her own birth and during her own early life, maternal growth and development, maternal age at conception, intergenesic intervals, maternal body characteristics and iron status at conception and during early pregnancy, gestational body weight gain, and iron status throughout gestation, particularly at conception and early pregnancy, and gestational body weight gain. Although less studied, paternal influences on the initiation and progression of pregnancy and on maternal environmental exposures are also important. Even though tools for the quantitative evaluation of women's iron status are very well developed, the quantitative estimation of body iron in the newborn and young infant remains a challenge. This article describes the crucial role played by the placenta in protecting the embryo and the fetus. In addition, neonatal health, particularly early in pregnancy, is briefly addressed, as are some important aspects of antenatal nutritional interventions that include iron.

Unlabelled: Iron and vitamin D are essential for physiological mechanisms underpinning physical capacities characterizing team-sport performance. Yet, the impact of iron deficiency on physical capacities beyond endurance is not clear.
Purpose: The purpose of this study was to assess variations in seasonal micronutrient concentrations and how iron deficiency impacts external-load measures in elite female rugby league players.

Iron plays a prominent role in various biological processes and is an essential element in almost all organisms, including plant-pathogenic fungi. As a transition element, iron occurs in two redox states, Fe and Fe, the transition between which generates distinct reactive oxygen species (ROS) such as HO, OH anions, and toxic OH· radicals. Thus, the redox status of Fe determines ROS formation in pathogen attack and plant defense and governs the outcome of pathogenic interactions.

To address this, we assess over 450 potential risk factors in one deeply clinically and demographically phenotyped cohort using random forest classifiers to determine predictive markers of poor cognitive function. This study aims to understand early risk factors for dementia by identifying predictors of poor cognitive performance amongst a comprehensive battery of imaging, blood, atmospheric pollutant and socio-economic measures.

Iron deficiency anaemia develops when there is not enough iron in the body to sustain normal red blood cell production. It is a major cause of morbidity worldwide and is linked to a range of comorbid conditions, including gastrointestinal cancer. In the UK, iron deficiency anaemia is the most common cause of anaemia identified in primary care and is estimated to affect 3% of men and 8% of women.

Background: Iron deficiency (ID) is the most common nutritional deficiency among patients undergoing major surgery. Treatment of ID is straightforward, however implementing a comprehensive anemia management strategy within clinical routines is complex. Recently, reticulocyte hemoglobin content (Ret-He) has been evaluated as an early marker for ID diagnosis.
