AI Article Synopsis
- The study analyzed the relationship between maternal iron status indicators and placental iron status in 38 first-time mothers who had normal deliveries.
- Measurements included maternal hemoglobin, soluble transferrin receptor, and serum ferritin, alongside various placental iron metrics obtained through different scientific methods.
- The findings indicated that there was no significant correlation between maternal and placental iron indicators, suggesting that maternal iron status does not accurately reflect the iron status of the placenta at the time of delivery.
Article Abstract
Indicators of maternal iron (Fe) status were studied in relation to placental Fe (Pl-Fe) status. Placental (Pl) and maternal (M) venous blood samples were obtained from primiparous women (n = 38), with normal delivery at Paroissien Hospital, Argentina. Maternal hemoglobin (M Hb), soluble transferrin receptor (M sTfR) (ELISA) and serum ferritin (M S-Ft) were studied in relation to Pl-Fe, ferritin (Pl-Ft) and transferrin receptor (Pl-TfR). Pl-TfR was measured by dot blot assay, Pl-Ft and M S-Ft by immunoassay (IRMA) and Pl-Fe by atomic absorption spectrometry. Fe status indicators were, respectively, (mean +/- SD): M Hb 113 +/- 16 g/L; M S-Ft 36 +/- 42 microg/L; M sTfR 6.3 +/- 3.1 mg/L; Pl-Fe 170 +/- 56 microg/g placenta; Pl-Ft 33 +/- 18 microg/g placenta; Pl-TfR 18 +/- 18 (range 0-58) microg/g placenta. Pl-Fe, Pl-Ft and Pl-TfR did not correlate to M Hb, M S-Ft and M sTfR. Women with Pl- Fe, Pl-Ft and Pl-TfR above or below the corresponding median values did not show any statistical significant difference in M Hb, M sTfR or M S-Ft values. Pl-Ft concentration was lower in women with Hb < 110 g/L than in women with normal values: 26 +/- 13 vs. 38 +/- 20 microg/g, respectively (p = 0.021). When Pl-TfR, Pl-Ft and Pl-Fe were compared in women with M S-Ft above or below the cut-off point of 10 or 20 microg/L, no significant difference was found for Pl-TfR neither for Pl-Ft nor Pl-Fe. These results suggest that maternal indicators of Fe status, particularly M sTfR and M S-Ft, do not reflect Fe status of the placenta at delivery.

Iron Deficiency and All-Cause Hospitalization Risk in a Clinical Cohort of COPD.

Background: The impact of iron deficiency on COPD morbidity independent of anemia status is unknown. Understanding the association between iron deficiency, anemia status, and risk of hospitalization in COPD may inform an approach to these comorbidities.
Study Design And Methods: Adults ≥40 years from the Johns Hopkins COPD Precision Medicine Center of Excellence data repository with an outpatient iron profile and 1 year of subsequent follow-up time were included in the study.

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.
