Objective To investigate pregnancy outcome for fetuses with nuchal translucency (NT) ≥3.5 mm but normal karyotype in the Stockholm (Sweden) area. Methods A retrospective population-based cohort study. From 2006 to 2012, fetal NT was measured in 55123 singleton pregnancies. There were 341 pregnancies with NT thickness ≥3.5 mm; 139 had a normal karyotype, 164 had an abnormal karyotype and 38 were removed from the study. Pregnancy outcome was defined as adverse (termination of pregnancy [TOP], miscarriage [MC], intrauterine fetal death [IUFD], or delivery of a child with structural defects or genetic disorders), or favourable (delivery of a child without any structural defects or genetic disorders diagnosed before discharge). Results Of the 139 high NT pregnancies with normal karyotype, 110 (79.2%) resulted in live births, one (0.7%) IUFD, 23 (16.5%) TOP and five (3.6%) MC. The risk of an adverse pregnancy outcome increased with increasing NT. Structural fetal defects were found in 28 (19.5%) of pregnancies undergoing second trimester ultrasound screening, of which seven resulted in live births and 21 were terminated. The most common structural defect was cardiac defects. Conclusions Adverse pregnancy outcome increased with increasing NT, even with normal karyotype, however, the prognosis is good if the second trimester ultrasound screening is normal.

Objectives: In low-risk pregnancies, the management of oligohydramnios is not clear. The aim of this study was to compare maternal and neonatal outcomes in cases of isolated oligohydramnios randomised to either induction of labour or expectant management. Methods: 87 women pregnant beyond 40 completed weeks were asked to participate in the study. Fifty-four accepted and were randomised at 288 days of pregnancy. Twenty-six were randomised to expectant management and 28 to induction of labour. The primary maternal outcome was the mode of delivery and the primary neonatal outcomes were cord blood pH and Apgar score at delivery. Results: No significant differences were found for any important maternal or neonatal outcome. Conclusion: Based on these results, the decisions about management could be individualised. Even though the number of patients included was small, these results are well in concordance with others. Copyright © 2005 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Amniotic fluid (AF) surrounds the growing fetus, and cells derived from AF are commonly used for diagnosis of genetic diseases. Intra-amniotic infections are strongly linked to preterm birth, which is the leading cause of perinatal mortality worldwide. Surprisingly little is known, however, about mature hematopoietic cells in AF, which could potentially be involved in immune responses during pregnancy. In this study, we show that the dominating population of viable CD45 + cells in AF is represented by a subset of fetal CD103 + group 3 innate lymphoid cells (ILCs) producing high levels of IL-17 and TNF. Fetal CD103 + ILC3s could also be detected at high frequency in second-trimester mucosal tissues (e.g., the intestine and lung). Taken together, our data indicate that CD103 + ILC3s accumulate with gestation in the fetal intestine and subsequently egress to the AF. The dominance of ILC3s producing IL-17 and TNF in AF suggests that they could be involved in controlling intra-amniotic infections and inflammation and as such could be important players in regulating subsequent premature birth., (Copyright © 2016 by The American Association of Immunologists, Inc.)
