Influence of chorionicity on perinatal outcome in a large cohort of Danish twin pregnancies.

To assess outcome in twin pregnancies according to chorionicity.

The Danish Fetal Medicine Database: establishment, organization and quality assessment of the first trimester screening program for trisomy 21 in Denmark 2008–2012

To describe the establishment and organization of the Danish Fetal Medicine Database and to report national results of first‐trimester combined screening for trisomy 21 in the 5‐year period 2008–2012.

Prenatal detection of congenital heart disease in a low risk population undergoing first and second trimester screening

The prenatal detection rate of congenital heart disease (CHD) is low compared with other fetal malformations. Our aim was to evaluate the prenatal detection of CHD in Eastern Denmark.

Increased nuchal translucency, normal karyotype and infant development

To investigate whether chromosomally normal fetuses with a nuchal translucency (NT) ≥ 99th percentile (3.5 mm) in the first trimester have an increased risk of delayed development at 2 years of age.

Cytokines and the risk of preterm delivery in twin pregnancies.

OBJECTIVE: To estimate the association between cytokine levels in twin pregnancies and risk of spontaneous preterm delivery, including the effect of progesterone treatment. METHODS: This secondary analysis of a randomized placebo-controlled trial investigating the effect of progesterone treatment on preterm delivery in twin pregnancies included 523 women with available dried blood spot samples collected before treatment with progesterone (n=258) or placebo (n=265) and after 4–8 weeks of treatment. Samples were analyzed for cytokines using a sandwich immunoassay. Cytokine levels in spontaneous preterm delivery at 34–37 weeks of gestation and spontaneous preterm delivery before 34 weeks of gestation were compared with delivery at 37 weeks of gestation or more for placebo-treated women. The association between interleukin (IL)-8 and risk of spontaneous preterm delivery before 34 weeks of gestation was estimated further, including comparison according to treatment. Statistical analyses included Kruskal-Wallis test, Mann-Whitney U test, linear regression, and Cox regression analysis. RESULTS: We found a statistically significant association between IL-8 and spontaneous preterm delivery. At 23–33 weeks of gestation, the median IL-8 level was 52 pg/mL (interquartile range 39–71, range 19–1,061) for term deliveries compared with 65 pg/mL (interquartile range 43–88, range 14–584) for spontaneous preterm delivery at 34–37 weeks of gestation and 75 pg/mL (interquartile range 57–102, range 22–1,715) for spontaneous preterm delivery before 34 weeks of gestation (P<.001). Risk of spontaneous preterm delivery was associated with a large weekly increase in IL-8 (hazard ratio 2.0, 95% confidence interval [CI] 1.2–3.3). There was no effect of progesterone treatment on IL-8 levels. Levels of IL-8 at 18–24 weeks of gestation were associated with a cervix less than 30 mm (odds ratio 1.8, 95% CI 1.2–2.7). CONCLUSION: Risk of spontaneous preterm delivery before 34 weeks of gestation is increased in women with high IL-8 levels. Progesterone treatment does not affect IL-8 levels.

Long‐term effects of prenatal progesterone exposure: neurophysiological development and hospital admissions in twins up to 8 years of age

To perform a neurophysiological follow‐up at 48 or 60 months of age in children exposed prenatally to progesterone compared with a placebo and evaluate their medical histories up to 8 years of age.

Late Sequelae after Laparoscopic Sterilization in the Pregnant and Non-Pregnant Woman

To determine the frequency of late sequelae after laparoscopic sterilization performed at the time of induced abortion, we compared data on 114 women who underwent induced first‐trimester abortion and concurrent laparoscopic sterilization, with 288 women who had sterilization performed at least 3 months after induced abortion. The period of observation was 12–95 months, median 49 months. We found no statistical difference between the groups with respect to failures, low abdominal pain, dyspareunia, change in bleeding pattern, sexual life and regrets. The results of these findings, discussed here, support the practice of performing the combined procedure.

Short- and long-term perinatal outcome in twin pregnancies affected by weight discordance

The objective was to investigate the association between chorionicity‐specific intertwin birthweight discordance and adverse outcomes including long‐term follow up at 6, 18, and 48–60 months after term via Ages and Stages Questionnaire.

Diagnosis and prediction of parental origin of triploidies by fetal nuchal translucency and maternal serum free β-hCG and PAPP-A at 11–14 weeks of gestation

The study objective was to determine the parental origin of triploidy in relation to findings from early risk assessment in a combined screening program between 2004 and the end of 2006. Triploidy was diagnosed in six chorion villus samples and two samples from missed abortions. After informed consent, quantitative fluorescence polymerase chain reaction analysis was performed on the five cases where we received blood from both parents and tissue from fetuses. In four cases the origin of the triploidy was paternal and in one maternal, in accordance with previous findings in type I and type II triploidies. Finding triploidy is possible by risk assessment (ultrasound and double test), and thereby women may have the opportunity for early termination of pregnancy.
