OBJECTIVES: This study aimed to investigate the association between first-trimester screening maternal serum markers (free human chorionic gonadotropin-beta (β-hCG), pregnancy-associated plasma protein-A, and adverse pregnancy outcomes (gestational hypertension, preeclampsia, preterm delivery, intrauterine growth restriction, oligohydramnios, intrauterine ex-fetus, abruptio placentae, and gestational diabetes mellitus). STUDY DESIGN: This was a retrospective cohort study including 1516 women who delivered a singleton pregnancy at GATA Haydarpasa Education Hospital from 2006 to 2009. Patients with multiple pregnancies, chromosome aberrations, or fetal anomalies were excluded. Extreme values of corrected- pregnancy-associated plasma protein-A and free β-hCG, and their association with adverse pregnancy outcomes were analyzed. RESULTS: Adverse pregnancy outcomes at the cutoff level of ≤0.25 c-pregnancy-associated plasma protein-A MOM values positive likelihood ratio (+LR) was 7.5 (95%CI 2.426-19.836) and had a significant correlation (r=0.108, p<0.01). It was also a significant correlation with adverse pregnancy outcomes (r=0.189, p<0.01) at the cut-off level of ≤0.50 corrected-pregnancy-associated plasma protein-A MOM values and the +LR was 2.388 (95%CI 1.889-2.991). Association between low corrected-pregnancy-associated plasma protein-A MOM values and adverse pregnancy outcomes were statistically significant and had a poor association (AUC, 0.630 95%CI 0.596-0.663, p<0.01). Preeclampsia was statistically significant, however had a fair association (AUC, 0.74 95% CI 0.690-0.802, p<0.01). Preterm birth was statistically significant but had a poor association (AUC, 0.568 95% CI 0.512-0.624, p<0.05). CONCLUSION: First-trimester maternal serum low pregnancy-associated plasma protein-A values are significantly associated with adverse pregnancy outcomes. It may be a useful tool to predictive not only chromosome anomalies but also adverse pregnancy outcomes.

Abstract ObjectivesTo investigate twin reversed arterial perfusion (TRAP) sequence for the prediction of TRAP-related adverse pregnancy outcomes at the gestational age of 11-14 weeks. MethodsPregnant women in the first trimester diagnosed with TRAP were recruited at West China Second University Hospital from January 2015 to June 2018. Systematic screening for the pump twin’s crown-rump length (CRL) and acardiac twin’s upper pole-rump length (URL) was conducted using ultrasonic detection. The (CRL-URL)/CRL and URL/CRL ratios were used to assess the pregnancy outcomes for the pump twin. ResultsTwenty-one pregnant women aged 21–39 years with a gestation of 11-14 weeks were recruited. TRAP was diagnosed on average (± standard deviation [SD]) at pregnancy week 13.1 ± 0.18. The pump twins’ mean (± SD) CRL was 6.65 ± 1.1 cm. The incidence of intrauterine death for the pump twins was 19.0% (n=4), the miscarriage rate was 14.3% (n=3), and the live birth rate was 66.7% (n=14). The (CRL-URL)/CRL ratios between the non-survival (intrauterine death and miscarriage) and survival groups significantly differed (0.33 ± 0.08 vs. 0.58 ± 0.08, p < 0.05). Similarly, the URL/CRL ratios between the non-survival and survival groups significantly differed (0.67 ± 0.08 vs. 0.42 ± 0.08, p < 0.05). ConclusionsThe (CRL-URL)/CRL and URL/CRL ratios were valuable indicators for determining pregnancy outcomes of pump twins with TRAP at an early gestational age.

ObjectiveTo study the associations between neighbourhood deprivation and fetal growth, including growth in the first trimester, and adverse pregnancy outcomes.DesignProspective cohort study.SettingThe Netherlands, Rotterdam.Participants8617 live singleton births from the Generation R cohort study.ExpositionLiving in a deprived neighbourhood.Main outcome measuresFetal growth trajectories of head circumference, weight and length.Secondary outcomes measuresSmall-for-gestational age (SGA) and preterm birth (PTB).ResultsNeighbourhood deprivation was not associated with first trimester growth. However, a higher neighbourhood status score (less deprivation) was associated with increased fetal growth in the second and third trimesters (eg, estimated fetal weight; adjusted regression coefficient 0.04, 95% CI 0.02 to 0.06). Less deprivation was also associated with decreased odds of SGA (adjusted OR 0.91, 95% CI 0.86 to 0.97, p=0.01) and PTB (adjusted OR 0.89, 95% CI 0.82 to 0.96, p=0.01).ConclusionsWe found an association between neighbourhood deprivation and fetal growth in the second and third trimester pregnancy, but not with first trimester growth. Less neighbourhood deprivation is associated with lower odds of adverse pregnancy outcomes. The associations remained after adjustment for individual-level risk factors. This supports the hypothesis that living in a deprived neighbourhood acts as an independent risk factor for fetal growth and adverse pregnancy outcomes, above and beyond individual risk factors.
