“…Degani et al 5 found that the antenatal UCI is higher than the postnatal UCI (0.44 ± 0.11 vs. 0.28 ± 0.08; P < 0.001). Furthermore, the antenatal UCI is lower in the third trimester than in the second trimester16. We found that the 90 th , 50 th and 10 th percentiles of the UCI were 0.578, 0.370 and 0.226, consistent with previous work13.…”

Mopping up: Phase‐selective gelators were synthesized from sugar alcohols using biocatalysis. The gelators exhibited an unprecedented ability to phase‐selectively gel only organic liquids including crude‐oil fractions in the presence of water at room temperature. Oil can be recovered from the gelled phase by heating and distillation. Thus this class of materials may be useful in recovering oil from spills.

BackgroundTo build a reference curve for the area of Wharton's jelly (WJ) in low-risk pregnancies from 13 to 40 weeks and to assess its relationship with estimated fetal weight (EFW).Methods2,189 low-risk pregnancies had the area of WJ estimated by ultrasound and the 10th, 50th and 90th percentiles calculated using a third-degree polynomial regression procedure. EFW by ultrasound was correlated with the measurement of the area of WJ.ResultsThe area of WJ increased according to gestational age (R2 = 0.64), stabilizing from the 32nd week onwards. There was a significant linear correlation between area of WJ and EFW up to 26 weeks (R = 0.782) and after that 5t remained practically constant (R = 0.047).ConclusionThe area of WJ increases according to gestational age, with a trend to stabilize at around 32 weeks of gestation. It is also linearly correlated with EFW only up to 26 weeks of gestation.

“…Throughout the entire pregnancy, the total length of umbilical cord is increased, and particularly, in the later period of pregnancy, the length of umbilical cord becomes longer every month by approximately 3 - 6 cm 6. A tendency is that the UCI becomes smaller in the third trimester in comparison with the second trimester7. Nonetheless, the level of the lengthening of umbilical cord varies in each fetus, and thus the change of UCI is individual.…”

Background: This study was conducted to determine whether or not the umbilical cord coiling index (UCI) during the late second trimester of gestation is associated with perinatal outcomes.Methods: This was a retrospective study of 251 pregnancies in which a fetal anatomic survey with a recorded UCI was performed at 22-28 weeks gestation. The subjects were divided into normocoiled, hypocoiled, and hypercoiled groups and compared perinatal outcomes.Results: Two hundred twenty-six patients were included. The incidence of preterm deliveries in hypocoiled group was 35%, which was significantly greater than the normocoiled groups (p=0.041). The incidence of neonates with low birth weights in the hypocoiled group was 36.4%, which was significantly greater than the normocoiled groups (p=0.044). In the hypocoiled group, 27.3% of newborns were admitted to the NICU which was significantly greater than the normocoiled and hypercoiled groups (p=0.041). After the adjustment by logistic regression analysis, only preterm delivery were significantly increased in hypocoiled group (OR=9.6, 95% CI=2.09-44.07).Conclusion: The hyporcoiling of the umbilical cord during the late second trimester of pregnancy suggest that the risk for preterm delivery is high, consequently the delivery of low birthweight neonates is high, and the admission to the neonatal intensive care unit is increased.
