Abstract

fetched live from OpenAlex

Background & Aims: Indian subcontinent has the highest child mortality rates along with a very high frequency of low birthweight (LBW).Folate and vitamin B12 (Vit-B12) are necessary during foetal development and their deficiency prevalence in Indians is very high.The objective of the present paper is to assess whether foetal homocysteine (Hcy)/folate metabolic pathway genes, their cofactors and homocysteine level independently (or collectively) predispose children to Low birth weight.Methods: Cord blood was collected for the study.Frequency of 5 SNPs in 4-Hcy-pathway genes, and levels of Hcy, Vit-B12 and folate were evaluated.Results: Of the 421 newborns recruited for the study, 38% showed low birth weight (<2.5kg) and 16% were preterm babies.101 neonates developed neonatal hyperbilirubinemia (NNH).High prevalence of Vit-B12 (65%) and folate (27%) deficiency was observed in newborns along with hyperhomocystinemia (hypHcy-25%).Preterm delivery, micronutrient deficiency, hypHcy and MTHFR 677T SNP are associated as risk factor while G allele of TCN2 C776G is protective against LBW.MTHFR 677T allele and folate deficiency are also independent risk factors for NNH. Conclusion:We record the highest incidence of Vit-B12, folate deficiency and elevated Hcy levels, of all the studies so far reported on neonates.These together with MTHFR 677T are potential risk factors for LBW.Association of impaired folate/Hcy metabolism with NNH is reported for the first time and the possible way of interaction is discussed.It appears that proper nutritional management during pregnancy would reduce the risk of complex clinical outcomes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
