AbstractAim:The aim of this study was to evaluate the predictive value of α-fetoprotein in maternal serum (MS-AFP) as a marker for diverse pregnancy outcomes.Methods:The study was based on pregnancy and delivery data from 5520 women between 1999 and 2014 at University Hospital of Zurich (UHZ). Inclusion criteria: both MS-AFP and pregnancy outcome were known for the same pregnancy. Pregnancy outcomes and characteristics such as fetal malformation, intrauterine fetal death (IUFD) and intrauterine growth retardation as well as maternal age, weight before pregnancy, gestational age (GA) at delivery, newborn weight, length and head circumference were analyzed with respect to the MS-AFP value. MS-AFP value was categorized into three groups: elevated MS-AFP>2.5 multiples of the median (MoM), normal 0.5–2.49 MoM and decreased <0.5 MoM.Results:Newborn weight (g) and length (cm) were significantly lower in the elevated MS-AFP (P<0.001) group, and infants had 1 week lower GA at delivery (P<0.05). In the group of elevated MS-AFP (n=46), 26.1% of pregnancies were significantly related to adverse pregnancy outcomes, such as fetal malformations, fetuses small for gestational age (SGA) and IUFD. Adverse pregnancy outcomes of 5.6% were registered in the group of normal MS-AFP and 7.3% in the group of low MS-AFP (P<0.05).Conclusion:MS-AFP level in the second trimester is still an important indicator of fetal surface malformations; however, ultrasound still outweighs as a screening method. Nevertheless, pregnant women with elevated MS-AFP values and with no sonographically detected fetal malformations should additionally receive the third trimester ultrasound examination to exclude other possible complications of pregnancy.

Background: Alpha-fetoprotein (AFP) is the major serum protein in the embryonic stage and in the early fetal stage. The aim of this study was to measure maternal serum AFP levels in second trimester between 15-20 weeks of gestation and to determine whether unexplained elevated MSAFP levels is an effective predictor of adverse pregnancy outcome among Indian population.Methods: This study was a prospective observational study, carried out on 400 pregnant women. Maternal serum alpha-fetoprotein (MSAFP) was measured between 15 and 20 weeks of gestation after excluding congenital malformation or birth defects. MSAFP level was determined by using a radio-immunoassay technique. Women with MSAFP level >2.0 MoM was considered as abnormal while MSAFP level≤ 2.0 MoM was considered as normal. All women were followed up till delivery and pregnancy outcomes were noted and compared between two groups.Results: Women with elevated MSAFP had significantly higher adverse pregnancy outcomes (75.4%) compared to women with MSAFP ≤2.0 MoM (26.1%) (p<0.0001 with relative risk of 2.89, 95% confidence interval 2.276 -3.667).Conclusions: Unexplained elevated MSAFP has high sensitivity, specificity, positive predictive value and negative predictive value in predicting adverse pregnancy outcomes. It would, therefore be worthwhile screening pregnant women in second trimester for maternal serum alpha-fetoprotein levels as it would help to identify high risk pregnancies and allow close antenatal survillence for better pregnancy outcome.

AbstractThe relevance of pregestational body mass index (BMI) on adverse pregnancy outcomes remained unclear in Southwest China. This study aimed to investigate the overall and age-category specific association between pre-gestational BMI and gestational diabetes mellitus (GDM), preeclampsia, cesarean delivery, preterm delivery, stillbirth, macrosomia, and small-for-gestational age (SGA) or large-for-gestational age (LGA) neonates in Southwest China. Furthermore, it explores the relative importance of influence of pregravid BMI and maternal age on pregnancy outcomes. 51,125 Chinese singleton pregnant women were recruited as study subjects. Multiple logistic regression models were used to examine the influence of pre-pregnancy BMI on adverse pregnancy outcomes. Gradient boosting machine was used to evaluate the relative importance of influence of pregravid BMI and maternal age on pregnancy outcomes. It is found that women who were overweight or obese before pregnancy are at higher risk of adverse pregnancy outcomes except for SGA neonates, while pre-pregnancy underweight is a protective factor for GDM, preeclampsia, cesarean delivery, macrosomia and LGA, but not SGA. Younger mothers are more susceptible to GDM and macrosomia neonates, while older mothers are more prone to preeclampsia. Pre-pregnancy BMI has more influence on various pregnancy outcomes than maternal age. To improve pregnancy outcomes, normal BMI weight as well as relatively young maternal ages are recommended for women in child-bearing age.

AbstractObjectivesTo compare the rate of fetal loss in pregnancy after second trimester amniocentesis between procedures performed by experts and non-experts and to assess other pregnancy complications as secondary outcomes.MethodsA retrospective cohort study was performed on singleton pregnancies that underwent mid-trimester amniocenteses in a single institution. The fetal loss rates of procedures performed by experts and non-experts were collected and analyzed. Other adverse pregnancy outcomes were also examined.ResultsIn total, 14,450 amniocenteses were performed during the study period. These included 11,357 (78.6%) procedures in the group expert operators and 3,093 (21.4%) procedures in the group non-expert operators. In the non-expert group, the fetal loss rate was slightly increased but not significantly (p=0.24).In addition, the higher number of spontaneous abortions was associated with blood-stained amniotic fluid sample (p<0.001; RR=9.28). Multiple needle insertions also increased in the non-expert group significantly. However, no difference in pregnancy outcomes was found between in single and multiple needle insertions.ConclusionsThe amniocentesis procedures performed by the non-experts was not increase the fetal loss rate. However, the other adverse pregnancy outcomes, including preterm birth, low birth weight and fetal growth restriction were significantly increased in the non-expert group.

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.
