Background: Fetal asphyxia and the consequent neurological damages could be avoided if the risk factors are controlled at earlier stages. Umbilical cord arterial blood gas (UCABG) seems to be related to the Apgar scores, as well as the neonatal morbidity and mortality rates. Therefore, we designed this study to assess the correlation between the Apgar score and UCABG i...

Introduction. To investigate the effect of complex umbilical cord entanglement primarily around the trunk on pregnancy outcomes. Methods. We studied 6307 pregnant women with singleton pregnancies who underwent vaginal delivery of an infant at ≥37 weeks of gestation. Cases were classified into no cord, nuchal cord, and body cord groups and defined as cases without umbilical cord entanglement, on...

The authors present their experience in prenatal diagnosis of placental and umbilical cord pathologies, using three-dimensional ultrasound (3DUS) in the rendering and tomography ultrasound imaging (TUI) modes, associated with color Doppler in some cases. Cases of placenta accreta/placenta previa, circumvallate placenta, succenturiate lobe, true knot of the umbilical cord, nuchal cord, and margi...

Introduction The increase in the use of breast feeding and the decrease in mothers' hospitalization in the past few years have caused  an increase in the infant bilirubin level, so it is necessary to introduce methods which can identify infants with higher risks of hyperbiliru binemia. The aim of this study is to determine the predictive value of measuring the umbilical cord bilirubin for patho...

background: in this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. materials and methods: human umbilical cord blood-derived mesenchymal stem cells were first cultured in dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incub...

The umbilical cord is a helical and tubular blood conduit connecting the foetus to the placenta. The umbilical cord achieves its final form by the 12th week of gestation and normally contains two arteries and a single vein, all embedded in Wharton's jelly. The structure of the umbilical cord receives only a cursory glance during many obstetric ultrasound examinations: with imaging limited to do...

BACKGROUND It has been established that presence of lean umbilical cord with reduced Wharton's jelly in sonographic scans is a fetal marker for risk of small for gestational age at birth. With improvement of ultrasound techniques, more studies have been investigating the alterations of the umbilical cord on pregnancy outcomes. OBJECTIVES To determine the reference ranges of the umbilical cord...
