Study Question. To determine whether the umbilical cord insertion site of singleton pregnancies could be linked to the newborn birth weight at term and its individual growth potential achievement.Material and Methods. A cohort study including 528 records of term neonates was performed. Each neonate was assessed for growth adjusted for gestational age according to the infant’s growth potential using the AUDIPOG module. We considered two categories of umbilical cord insertions: central and peripheral. Intrauterine growth restriction was defined as birth weight below the 10th percentile. Statistical analysis was performed using Chi-square, Student’sttest, Wilcoxon test, ANOVA, and logistic regression.Results. We observed a total of 343 centrally inserted cords versus 185 peripheral cords. There were twice as many smokers in the mothers of the peripheral category compared to the centrally inserted ones. More importantly, we demonstrated that only 17/343 (5.0%) of infants with central cord insertion were growth restricted, compared to 37/185 (20.0%) of the infants born with a peripheral insertion. Neonates with centrally inserted cord were significantly heavier.Conclusion. The umbilical cord insertion site of singleton pregnancies is associated with the newborn’s birth weight at term and its individual growth potential achievement.

The aim of the study was to determine the effect of the displacement of the umbilical cord insertion site from the centre of the placenta on the placental mass and the birth weight of dichorionic diamniotic twins and to consider the importance of the direction of the displacement, as well as to assess the influence of the umbilical cord displacement on the placental mass and the birth weight of dichorionic diamniotic twins taking into account the direction of displacement. Material and methods. The study was performed on 135 dichorionic diamniotic pairs: 68 opposite-sex, 35 same-sex males, and 32 same-sex females. The impact of an absolute cord displacement from the centroid of the placental disc and the direction of its shifting were compared with the birth weight and the placental mass. Results. In the investigated group, a central insertion was revealed in 6 (2.2 %), eccentric – in 224 (83.0 %), marginal – in 31 (11.5 %), and velamentous – in 9 (3.3 %) cases. The first two types of cord insertion are considered to be normal, the third and the fourth are seen as abnormal. The placental mass was in a strong positive correlation with the birth weight (r=0.71, p<0.0001). The placentas with an eccentric cord insertion had a smaller surface area. A negative correlation was established between the displacement of the cord insertion site and the placental mass (r=-0.4284, p<0.0001) as well as the birth weight (r=-0.6115, p<0.0001). The shift along the long axis was of greater importance than in relation to the shorter one. The placental mass and the birth weight were higher in the new-borns with a normal cord insertion site. In the abnormal cord insertion group, 32.5 % of the infants were under the 10th birth weight percentile, in the normal cord insertion group – only 8.3 %. Conclusions. The birth weight of dichorionic diamniotic twins and their placental mass are negatively correlated with the distance of the umbilical cord insertion site from the placental centre. The insertion site displacement along the long axis has a stronger negative effect on the birth weight and the placental mass in comparison with the shifting along the short axis. The placentas with an eccentric cord insertion have a smaller surface area.

Background: Hypertensive disorders in pregnancy are responsible for significant amount of maternal and perinatal morbidity and mortality. This study was designed to see the association of umbilical cord insretion on placenta in hypertensive mothers. Objective: This purpose of the present stufdy was to find out the site of umbilical cord insertion on placenta in pregnancy associated with hypertension and to correlate it with the weight of the placenta and the condition of the newborn. Methodology: This descriptive cross-sectional study was conducted at the Department of Anatomy, Rajshahi Medical College and Department of Obstetrics & Gynaecology at Rajshahi Medical College & Hospital, Bangladesh. Placental weight, diameter, thickness, insertion site of umbilical cord, insertion percentage of the cord and weight of newborn were noted. The site of cord insertion was detected and insertion percentage was calculated with the help of d/r x 100. Results: A total 130 cases were selected for the study, 30 from normal, 33 from mild, 34 from moderate and 33 from severe hypertensive group respectively. The study demonstrated that mild to severe hypertension had smaller placentas with the tendency of deviation of umbilical cord towards the margin for insertion. Newborns of such mothers had low birth weight mostly; few of them had birth asphyxia.Conclusion: This study has been established that the marginal insertion of umbilical cord on placenta is associated with hypertension and severity of hypertension deviates the insertion site towards the margin.Journal of National Institute of Neurosciences Bangladesh, 2016;2(2): 89-93

Placental Structure

Suboptimal fetal growth has been associated with an increased risk of adult disease, which may be exacerbated by an increased placental weight–to–fetal weight ratio. Placental weight is a summary measure of placental growth and development throughout pregnancy. However, measures of placental structure, including the chorionic disk surface area and thickness and eccentricity of the umbilical cord insertion, have been shown to account for additional variance in birth weight beyond that explained by placental weight. Little is known of the variability of these placental parameters in low-risk populations; their association with maternal, pregnancy, and neonatal characteristics; and the agreement between manual and digital measures. This study used manual and digital image analysis techniques to examine gross placental anatomy in 513 low-risk, singleton, term, first-born infants. Parametric methods compared groups and examined relationships among variables. Maternal birth weight, prepregnancy weight, and body mass index were associated with increased placental and birth weight (all P < 0.005), but only maternal birth weight was associated with increased placental surface area ( P < 0.0005) and thickness ( P = 0.005). Smoking during pregnancy reduced birth weight and increased the eccentricity of umbilical cord insertion ( P = 0.012 and 0.034, respectively). The variability in these placental parameters was consistently lower than that reported in the literature, and correlations between digital and manual measurements were reasonable ( r = .87–.71). Detailed analyses of gross placental structure can provide biologically relevant information regarding placental growth and development and, potentially, their consequences.

Ghrelin has orexigenic effects. It is present in umbilical cord plasma in full-term neonates, raising the prospect that ghrelin plays a role in fetal and neonatal energy balance. We measured ghrelin in small (SGA), appropriate (AGA), and large (LGA) for gestational age neonates and evaluated whether ghrelin levels are modulated by neonatal insulin and glucose concentrations. Plasma concentrations of ghrelin, insulin, and glucose were measured in cord blood sampled at birth in 123 SGA, AGA, and LGA neonates (gestational age, 24–41 wk) born to mothers with and without diabetes. Ghrelin was detected in samples from all infants. Its concentration was 40% higher in SGA neonates (mean ± sd, 2436 ± 657 pg/ml) compared with AGA (1738 ± 380) and LGA (1723 ± 269) neonates. There was a positive correlation between ghrelin and gestational age in AGA/LGA (r = 0.23; P &lt; 0.05) and a negative correlation in SGA (r = −0.67; P &lt; 0.005) neonates. Therefore, the difference in ghrelin between SGA and AGA/LGA neonates decreases with advancing gestational age. Birth weight z-score, maternal hypertension, and glucose concentrations were significant determinants of ghrelin concentrations. In conclusion, SGA neonates present with higher umbilical cord ghrelin plasma concentrations than AGA/LGA neonates. Ghrelin may play a physiological role in fetal adaptation to intrauterine malnutrition.
