Zinc Levels

1. The levels of zinc in plasma, erythrocytes, polymorphonuclear (PMN) and mononuclear (MN) white cells were measured after delivery in women giving birth to appropriate-for-gestational-age (AGA) babies (group I mothers), or small-for-gestational-age (SGA) babies (group II mothers) and in non-pregnant controls. 2. Mean maternal plasma zinc and albumin levels 24-48 h after delivery were lower than in controls, but PMN and MN zinc levels were unchanged. PMN zinc levels were lower than those of MN cells. 3. PMN and MN zinc levels were significantly lower in group II mothers than in group I, irrespective of smoking habits. There were no racial differences in peripheral white cell zinc levels. 4. PMN, and to a lesser degree MN, zinc levels were lower in smoking than in non-smoking mothers. 5. Erythrocyte zinc did not correlate with other zinc measurements nor with the size of the babies. Fetal erythrocyte zinc levels were one-third of maternal levels. 6. A combination of smoking and/or low PMN zinc levels selects 85% of mothers having small-for-gestational-age babies.

Multivariable Logistic Regression Model

IntroductionRacial differences in the association between type 1 diabetes mellitus (T1DM) and large-for-gestational-age (LGA) neonates remain unclear. The objective of this study was to compare the effect of T1DM on LGA neonates between Caucasian and Asian women.Research design and methodsA population-based retrospective cohort study was conducted among Caucasian and Asian women who had prenatal screening and gave a singleton live birth in an Ontario hospital between April 2015 and March 2018. Multivariable log-binomial regression models were used to estimate the adjusted relative risks (aRRs) and 95% CIs of T1DM on LGA for Caucasian and Asian women. Relative contribution of T1DM to LGA was examined by multivariable logistic regression model, stratified by Caucasian and Asian women.ResultsA total of 232 503 women (69.4% Caucasians and 30.6% Asians) were included in the final analysis. The rate of T1DM was higher in Caucasians (0.5%) than in Asians (0.2%), and the rate of LGA neonates was also higher in Caucasians (11.0%) than in Asians (5.0%). The association between T1DM and LGA in Caucasians (aRR 4.18, 95% CI (3.84 to 4.55)) was more robust than that in Asians (aRR 2.11, 95% CI (1.24 to 3.59)). T1DM was the fourth strongest contributor to LGA in Caucasians, while T1DM was the seventh contributor to LGA in Asians.ConclusionsT1DM plays a more substantial role in LGA among Caucasians than Asians. Clinicians should be aware of the Caucasian–Asian differences of effects of T1DM on LGA when developing pregnancy management strategies.

Physical Index

It has been known that the development of skin creases on the sole of the foot occurs in late intrauterine life and that after birth this is a helpful clinical sign to determine gestational age. Until 36 weeks of gestation there are only one or two transverse skin creases on the anterior part of the sole. The posterior two-thirds of the sole are smooth. By 37 to 38 weeks of gestation more creases have appeared and in the full-term infant there is a complex series of criss-crossed creases covering the entire sole. Since no racial differences in the presence or absence of this sign have ever been published a study was designed to compare the development of skin creases on the sole of the foot between Caucasian and Negro newborn infants.

Background: Brain natriuretic peptide (BNP) is a sensitive biomarker that is valuable in the management of childhood heart failure. Studies have reported racial differences in the level of BNP, especially in the adult population. The level of BNP in healthy Nigerian newborn babies is unknown. Hence, we determined the level of BNP in healthy term appropriate for gestational age (AGA) newborn babies. Methods: This was a cross sectional study,85 healthy term AGA newborn babies aged 24 to 72 hours. The babies had relevant demographic parameters documented in a proforma and BNP assay analysed using ELISA method. Results: The median IQR serum BNP level was 341.43 (313.39 to 425.45) pg/ml. The median level in females, was higher than males, {393.86 (296.97- 460.62) pg/ml vs328.05 (313.61-389.39) pg/ml, p >0.05}.There was no significant relationship between serum BNP and birth weight, chronological age, gestational age, or mode of delivery (p>0.05 in each case). Conclusion: The study demonstrated high BNP levels in healthy term Nigerian newborns. There was no relationship between BNP, the chronological age, birth weight, gender, gestational age or mode of delivery in babies between 24 to 72 hours of life.
