Monochorionic twin pregnancies are at increased risk for adverse outcome compared to dichorionic twin pregnancies and singletons. Monochorionic-specific complications include twin-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence, single intrauterine fetal demise and its consequences on the co-twin, and selective intrauterine growth restriction. Whereas the natural history of monochorionic-specific complications carries a high risk of fetal death or severe neurologic disability, a framework now exists, based on well-designed clinical trials, for optimal treatment of these entities...

STUDY QUESTION: Do fatty acids regulate development and motility of human extravillous trophoblast cells (EVTs)? SUMMARY ANSWER: Oleic acid is a promising lipid molecule that has beneficial effects on motility and development of human EVTs. WHAT IS KNOWN ALREADY: Fatty acid uptake into trophoblast cells is important for maintaining cellular events during pregnancy, but the molecular mechanisms of action of various fatty acids, including trans fatty acids, saturated fatty acids and monounsaturated fatty acids, in EVT cell lines are not clear...

Women with twin or higher-order pregnancies will typically have more ultrasound examinations than women with a singleton pregnancy. Most women will have at minimum a first trimester scan, a nuchal translucency evaluation scan, fetal anatomy scan at 18 to 22 weeks, and one or more scans in the third trimester to evaluate growth. Multiple gestations are at higher risk for preterm delivery, congenital anomalies, fetal growth restriction, placenta previa, vasa previa, and velamentous cord insertion. Chorionicity and amnionicity should be determined as early as possible when a twin pregnancy is identified to permit triage of the monochorionic group into a closer surveillance model...

BACKGROUND: Screening for, diagnosis and management of intrauterine growth restriction (IUGR) is often performed in multidisciplinary collaboration. However, variation in screening methods, diagnosis and management of IUGR may lead to confusion. In the Netherlands two monodisciplinary guidelines on IUGR do not fully align. To facilitate effective collaboration between different professionals in perinatal care, we undertook a Delphi study with uniform recommendations as our primary result, focusing on issues that are not aligned or for which specifications are lacking in the current guidelines...

OBJECTIVE: The aim of this study was to investigate the association between abnormal cord insertion and the development of the twin-specific complications, including birthweight discordance, selective fetal growth restriction (sFGR) and twin-to-twin transfusion syndrome (TTTS). METHODS: A single-center cohort study of twin pregnancies. Abnormal cord insertion was defined as either marginal (cord attachment site less than 2cm to the nearest margin of the placental disc) or velamentous (when the umbilical cord was attached to the membrane before reaching the placental disc with clear evidence of vessels traversing the membranes to connect with the placental disc), as described in placental pathology reports...

The microRNA (miRNA) profiles of placentas complicated with selective intrauterine growth restriction (sIUGR) are unknown. In the present study, the sIUGR‑associated placental miRNA expression was investigated using microarray and confirmatory reverse transcriptase‑quantitative polymerase chain reaction studies. Placenta samples around the individual insertion region for each umbilical cord were collected from monochorionic twins complicated with (n=17) or without sIUGR (control, n=16). miRNA profile analysis was performed on two sIUGR cases and one control using an Affymetrix microRNA 4...

It is challenging to characterize and classify normal and abnormal brain development during early childhood. To reduce the complexity of heterogeneous data population, manifold learning techniques are increasingly applied, which find a low-dimensional representation of the data, while preserving all relevant information. The neighborhood definition used for constructing manifold representations of the population is crucial for preserving the similarity structure and it is highly application dependent. The recently proposed neighborhood approximation forests learn a neighborhood structure in a dataset based on a user-defined distance...

Fetal malformations are more frequent in twins than in singletons. The aim of our study was to define the influence of a malformed twin on di-chorionic pregnancy outcomes. We performed a retrospective cohort study of di-chorionic pregnancies delivered between 2000 and 2015. Exclusion criteria were: both twins affected by fetal malformations, double intra-uterine fetal death in pregnancies without fetal malformation, selective feticide and therapeutic pregnancy termination. We compared maternal and fetal outcomes of di-chorionic pregnancies not complicated by fetal malformations with pregnancies affected by a single malformed fetus with conservative management...

Intrauterine growth restriction (IUGR) is associated with foetal cardiac remodelling and dysfunction together with increased risk of cardiovascular disease in adulthood. Experimental data concerning effects of IUGR on cardiomyocyte and microvascularization anatomy are inconsistent and it is unknown whether both ventricles are similarly susceptible to in utero undersupply. Foetal IUGR was induced in pregnant rabbits at 25 days of gestation by selective ligation of uteroplacental vessels. Foetal echocardiography showed systolic and diastolic dysfunction of both ventricles and body and heart weight were significantly reduced in response to IUGR...

BACKGROUND: Intrauterine growth restriction (IUGR) is caused by fetal growth below what is normal for its genetic potential. Recent studies have shown a distinct association between changes in umbilical artery flow in IUGR subjects and an increased risk of respiratory morbidity and was to find the impact of IUGR on the respiratory outcomes of premature neonates born with less than 32 weeks gestational age. METHODS: This retrospective cohort study targeted infants born with less than 32 weeks of gestation, admitted at NCIU, between January 2010 and December 2016...
