The aim of this study was to examine the prevalence of embryologic remnants in umbilical cords of different gestational ages. Sections from 392 umbilical cords were examined using light microscopy. Of these, 52% contained at least 1 remnant, most commonly of the allantoic duct type. Although there was a significant decrease in vitelline duct remnants over increasing gestational age, from 11% at weeks 11–25 to 1.6% at weeks 36–42 ( P = .009; χ2 test), the allantoic duct remnants remained constant in prevalence irrespective of gestational age.

Objective The fetal inflammatory response syndrome (FIRS) is characterized by elevated concentrations of inflammatory cytokines in fetal blood, with preterm delivery and morbidity. Umbilical cord serum interleukin-6 (UC-s-IL-6) is an ideal marker for detecting FIRS. However, the effect of gestational age (GA) on UC-s-IL-6 levels has not been reported. This study aimed to determine the relationship between GA and UC-s-IL-6 levels, and GA-dependent cutoff values of UC-s-IL-6 levels for detecting fetal inflammation. Study Design UC-s-IL-6 concentrations were measured in 194 newborns (44 extremely preterm newborns (EPNs) at 22–27 weeks' GA, 68 very preterm newborns (VPNs) at 28–31 weeks' GA, and 82 preterm newborns (PNs) at 32–34 weeks' GA). Linear regression analyses were used to correlate GA and UC-s-IL-6 levels. Receiver operating characteristic (ROC) curves analyses were performed for detecting the presence of funisitis, as the histopathological counterpart of FIRS. Results A significant negative correlation between GA and UC-s-IL-6 levels was found in newborns with severe funisitis (r s =  − 0.427, p = 0.004) and those with mild funisitis (r s =  − 0.396, p = 0.025). ROC curve analyses revealed the area under the curve for detecting funisitis were 0.856, 0.837, and 0.622 in EPNs, VPNs, and PNs, respectively. The UC-s-IL-6 cutoff value in EPNs (28.1 pg/mL) exceeded those in VPNs and PNs (3.7 and 3.0 pg/mL, respectively). Conclusion UC-s-IL-6 levels were inversely correlated with GA especially in newborns with funisitis. Such GA dependency of UC-s-IL-6 should be considered for detecting fetal inflammation. Key Points

Objective The aim of the study is to describe the rates of neonatal death and severe neonatal morbidity in a contemporary cohort, as well as to evaluate the predictive value of birth gestational age (GA) and birth weight, independently and combined, for neonatal mortality and morbidity in the same contemporary cohort. Study Design We performed a secondary analysis of an international, multicenter randomized controlled trial of delayed umbilical cord clamping versus umbilical cord milking in preterm infants born at 23 0/7 to 31 6/7 weeks of gestation. The current analysis was restricted to infants delivered <28 weeks. The primary outcomes of this analysis were neonatal death and a composite of severe neonatal morbidity. Incidence of outcomes was compared by weeks of GA, with planned subanalysis comparing small for gestational age (SGA) versus non-SGA neonates. Multivariable logistic regression was then used to model these outcomes based on birth GA, birth weight, or a combination of both as primary independent predictors to determine which had superior ability to predict outcomes. Results Of 474 neonates in the original trial, 180 (38%) were included in this analysis. Overall, death occurred in 27 (15%) and severe morbidity in 139 (77%) neonates. Rates of mortality and morbidity declined with increasing GA (mortality 54% at 23 vs. 9% at 27 weeks). SGA infants (n = 25) had significantly higher mortality compared with non-SGA infants across all GAs (p < 0.01). There was no difference in the predictive value for neonatal death or severe morbidity between the three prediction options (GA, birth weight, or GA and birth weight). Conclusion Death and severe neonatal morbidity declined with advancing GA, with higher rates of death in SGA infants. Birth GA and birth weight were both good predictors of outcomes; however, combining the two was not more predictive, even in SGA infants. Key Points

Background: A right-sided umbilical cord twist is associated with the presence of a single umbilical artery, congenital malformations and placenta praevia. Methods: It was an observational study. Data was collected from 137 umbilical cords, all from live births and their patient records. The gestational ages ranged from 28 weeks to 41 weeks. The umbilical cords were categorized into right or left, based on the direction of twist. The independent sample T test and the Chi square test were used to analyze the differences between groups. Results: The prevalence of left twist was 84%. Right twist was significantly associated with a larger Hyrtl’s anastomosis (p=0.029) and gestational diabetes (p=0.027). Conclusion: Two previously unreported associations with right twist of the umbilical cord, gestational diabetes and an increase in the diameter of Hyrtl’s anastomosis, were noted in the present study.

Abstract Typically, sows are induced to farrow using prostaglandin followed by an injection of oxytocin 24 hours later. Benefits of induction can include decreased rate of stillbirths, dystocia, and postnatal mortality along with increasing the likelihood of farrowings being attended. Several studies have indicated that oxytocin administration may negatively impact fetal oxygen supply during parturition, potentially from umbilical cords breaking prior to birth, resulting in increased preweaning mortality. Therefore, the objective of this study was to determine if various induction protocols impact umbilical cord breakage and fetal blood parameters at birth. Fifty-eight primiparous and multiparous sows were assigned to one of three treatments: no induction (NO; n=24), or 2 cc Lutalyse administered on d114 of gestation followed by either 1 cc of oxytocin 24 hours later (OXY24; n=13) or 0.5 cc of oxytocin at 6 and 12 hours after Lutalyse (OXY6; n=21). Details of the farrowing process were recorded, and umbilical cord blood was collected from piglets at birth and evaluated on an iSTAT machine using an Abbott EC8+ test cartridge. There were no differences in total born, number born alive, stillborns, mummies, or assistance needed during farrowing. Sows in the OXY24 treatment tended to have longer farrowings when compared to both NO and OXY6 (5.6 vs 3.7 vs 3.7 hours; P=0.09). OXY24 gilts (38%) and NO sows (33%) tended to have more piglets born with broken umbilical cords than other parities and treatments (OXY24 sows: 19%; NO gilts: 18%; OXY6 gilts: 25%; OXY6 sows: 18%; P=0.07). Piglets born from NO sows had higher base excess, total carbon dioxide, and glucose which suggests that these piglets had prolonged moments of asphyxiation (P&lt; 0.01). OXY24 piglets had the lowest blood pH which is indicative of hypoxic birthing conditions (P&lt; 0.01). There were no signs of asphyxia in the blood parameters of piglets born from OXY6 sows. Therefore, multiple low doses of oxytocin to induce farrowing may be more beneficial for the welfare of the piglet during farrowing.

Abstract Context.—The cause for intrauterine fetal demise (IUFD) occurring in early gestation in a high percentage of spontaneous abortions is unknown. Objective.—To determine the association, if any, of umbilical cord abnormalities with early IUFD. Design.—All cases of IUFD occurring within 16 weeks of gestation that presented to our hospitals between August 1998 and July 2001 were prospectively studied. Once the fetal demise was diagnosed, pregnancy was terminated by medical induction, such that the products of conception were largely delivered intact. Cases with an intact umbilical cord connecting the fetus and placenta were considered in the study, whereas disrupted cord and curettage material was excluded from the study. Results.—A total of 153 early IUFD cases were seen during the period of study. The medical induction yielded intact products of conception in 122 cases, whereas 31 cases had to be completed by curettage, as the expulsion of the conceptus was incomplete. Thirteen of the 122 IUFD cases showed abnormalities of the umbilical cord. The cord lesions most frequently encountered were constriction and coiling abnormalities. Other lesions seen included hemorrhage, thrombosis, edema, and amniotic band. Conclusions.—A significantly high number (10.7%) of IUFD in early gestation are associated with umbilical cord abnormalities. Routine assessment of umbilical cords in early pregnancy might help to detect pregnancies at risk.
