Effect of Maternal Iron Deficiency Anaemia on the Expression of Iron Transport Proteins in the Third Trimester Placenta.

BackgroundDuring pregnancy, iron is transferred from mother to fetus with placental iron transport proteins (Transferrin receptor, Divalent metal transporter/DMT1, ferroportin/FPN1 and Zyklopen). The aim of the study was to evaluate the effect of maternal iron deficiency anemia on placental iron transporters. Study Design: Two hundred pregnant women, in third trimester of pregnancy were divided into anemic (Hemoglobin/Hb < 11g/dl) and non-anemic groups (Hb ≥ 11 g/dl). After delivery, placental expression of iron transport proteins were studied by immunohistochemistry and by mRNA analysis. Results: Of the 200 subjects, 59% were anemic. All 3 placental proteins showed statistically significant increase in immunohistochemical expression, proportionate to the severity of maternal anemia. The mRNA expression of DMT-1 gene was only significantly elevated in placentas of anemic mothers. Conclusion: Although in our study mRNA expression of only the DMT-1 gene was significantly high, immunohistochemically however all the 3 proteins showed significantly higher expression in placentas of anemic mothers.

Maternal MUAC and fetal outcome in an Indian tertiary care hospital: A prospective observational study.

Studies to date demonstrated the relatedness of mid-upper arm circumference (MUAC) measurement of pregnant women to their anthropometry/weight. Hence, the objective was to determine whether maternal MUAC at different gestational age predicted birthweight, and if so, to identify which cut-offs provided the best prediction of low birthweight (LBW) in pregnant women cohort. A total of 928 pregnant women, free of any obstetrical and medical complications known to affect fetal growth, were followed from 20 to 24 weeks' gestation till delivery. Weight, height, and MUAC were determined for the pregnant women, and gestational age along with newborns anthropometry was collected. The mean birthweight was 2.6 ± 0.460 kg. Maternal age, height, weight, MUAC (three time points), gestational age at delivery, and post-natal weight showed positive correlation with birthweight, crown heel length, and head circumference of the neonates. The cut-off limit with the best sensitivity-specificity (54.0 and 59.8, respectively) for MUAC was 23 cm, whereas maternal weight of 55 kg had sensitivity and specificity of 62.5 and 59.9 for predicting LBW. Maternal weight of 55 kg and MUAC value of 23 cm had almost similar sensitivity and specificity for predicting LBW. MUAC (≤23 cm) can be considered as a potential indicator of LBW where weighing of pregnant women is not feasible or when presentation for antenatal care is late, especially where pre-pregnancy weights are not available.

Reduction of α-galactoside content in red gram (Cajanus cajan L.) upon germination followed by heat treatment.

BACKGROUND: Red gram (Cajanus cajan L.) is an important crop for human and animal nutrition. However, raffinose family oligosaccharides present in red gram seed hinder its consumption as it is not digested by normal human carbohydrases and is further fermented by intestinal microflora, which induces flatulence. In order to make the grain legume more amenable for human consumption, we have tried to shed some light on the effect of germination followed by heat treatment methods such as autoclaving, cooking and pressure cooking on the raffinose family of sugars. These techniques, however, are primary prerequisites before consumption of the gram. RESULTS: The percent removal of raffinose, stachyose and verbascose after germinating red gram seeds for 8 h followed by autoclaving was 65.6%, 58.9% and 65.3% respectively; and after cooking was 61.6%, 69.2% and 72.5%. Germinating for 16 h followed by autoclaving led to a mean decrease of 53.3% for raffinose, 60.3% for stachyose and 62.3% for verbascose. Germination of red gram seeds for 16 h followed by cooking led to a mean decrease of 71.7% for raffinose, 76.2% for stachyose and 74.0% for verbascose, respectively. The results for the percent removal of raffinose, stachyose and verbascose after germination of red gram seeds for 16 h followed by pressure cooking was 68.3%, 73.3% and 68.2% respectively. CONCLUSION: This study demonstrates that local methods of processing reduce raffinose family oligosaccharides in red gram. The technique of germinating the seeds for 16 h followed by autoclaving, cooking and pressure cooking for the reduction of raffinose family oligosaccharides is a promising solution to overcome flatulence and increase the overall acceptance of red gram among general populace.
