RESUMO
BACKGROUND: An optimal approach for providing sufficient antenatal surveillance for fetal growth restriction (FGR) has yet to be elucidated. Moreover, there is scant literature on the fetal response to betamethasone and its effect on fetal Dopplers. OBJECTIVE: To compare persistence of umbilical artery Doppler abnormalities after corticosteroid administration and adverse perinatal outcome in growth restricted fetuses. METHODS: Retrospective cohort study (2008-2018) of singleton gestations with FGR (EFW <10th percentile) and umbilical artery Doppler abnormalities (absent or reversed end diastolic velocity) between 24 and 34 weeks of gestation at two institutions. Included patients had Dopplers performed before betamethasone administration and again within 1 week. Excluded were multiple gestations, chromosomal abnormalities, fetal anomalies, or missing outcome information. Pregnancies with persistently abnormal Dopplers were compared with those in which an improvement of Dopplers was noted. The primary outcome was a composite that consisted of indicated preterm birth <32 weeks, 1 or 5 min APGAR score <7, intrauterine fetal demise, and neonatal demise. Secondary outcomes included length of NICU stay, ventilator support, gestational age at delivery, interval between steroids and delivery, and birth weight. RESULTS: Fifty-three FGR pregnancies met inclusion criteria. Umbilical artery Dopplers improved after steroids in 32% (n = 17). No difference in the frequency of the primary outcome was observed between the persistently abnormal Doppler and improved Doppler groups (72.2% vs. 70.6%, respectively), and there was no difference in any of the secondary outcomes. CONCLUSIONS: Perinatal outcomes in FGR pregnancies were not affected by improved versus persistently abnormal umbilical artery Dopplers after betamethasone administration.

To determine if circulating levels of maternal syndecan-1, a part of the endothelial glycocalyx, change over gestational weeks 11-13 and if first trimester serum syndecan-1 levels are aberrant in women with adverse pregnancy outcomes vs. controls. Dried blood samples from 300 randomly selected women (100 each from gestational weeks 11, 12, and 13) who delivered at Northwell Health were assessed for syndecan-1 levels. Subjects were segregated by gestational age and maternal weight at the time of blood draw. Gestational age-specific medians were determined by linear regression of median syndecan-1 values vs. gestational age. Multiples of the median (MoMs) = syndecan-1/respective gestational age-specific regressed median. After determining a normal range, we performed a case-control study. Cases (n = 119) were singleton pregnancies with preeclampsia or fetal growth restriction who delivered at 20-36 6/7 weeks with 1st trimester conventional aneuploidy screens; 2 controls (n = 238) per case were identified and assessed. Syndecan-1 levels were determined by ELISA. Data were reported as MoMs and analyzed based on Wilcoxon rank-sum test and Fisher's exact test. A progressive and significant increase in median circulating Sdc1 concentrations was observed from gestational weeks 11-13 (p < 0.001). There was no significant difference in median syndecan-1 MoM values among cases and controls (p = 0.22). However, a subgroup of cases (17.6%) had extreme syndecan-1 values (≤ 0.5MoM) vs. 6.7% of controls (p = 0.003, OR = 3.0). Serum syndecan-1 concentrations significantly increase during gestational weeks 11-13. Extremely low 1st trimester serum syndecan-1 values are associated with an increased risk of adverse pregnancy outcome.

Objective: To determine if vaginal misoprostol is more effective than oral misoprostol for cervical ripening in obese women.Study design: A retrospective cohort study of obese women undergoing induction of labor from Jan 2013 to Dec 2016 with singleton, viable pregnancies beyond 37 completed weeks of gestational age. Women with an initial Bishop score of 7 or less, with a cervical dilatation of less than 2 cm, who received either vaginal or oral misoprostol as a cervical ripening agent, were included. Primary outcome was interval from the start of induction to the attainment of 3 cm cervical dilatation. Secondary outcomes included the interval from the start of induction to delivery and the rate of cesarean delivery (CD).Result: Of women who met the inclusion criteria, 966 (75.5%) women received oral misoprostol and 314 (24.5%) received vaginal misoprostol. The mean time-interval from the start of induction to attainment of 3-cm dilatation was shorter in the vaginal group (10.5 ± 10.4 h) compared to the oral group (17.2 ± 11.5 h), (p < .0001). Significantly shorter times to delivery were also noted in the vaginal group (17.4 h for vaginal vs. 24.8 h for oral, p < .0001). In the subgroup analysis of nulliparous women, shorter time intervals from the start of induction to attainment of 3-cm dilatation, as well as to delivery, were noted in the vaginal misoprostol group (p < .0001 for both). Multiple linear regression model confirmed route of misoprostol administration as an independent variable in predicting the outcomes (time from start of induction to 3 cm as well as to delivery). Significant findings amongst neonatal outcomes included lower umbilical artery pH and higher rates of neonatal jaundice in the oral misoprostol group.Conclusion: In a population of obese women undergoing induction of labor, vaginal administration of misoprostol was associated shorter time intervals from the start of induction to the attainment of 3 cm of dilatation, as well as to delivery, without increasing the rate of cesarean deliveries or the incidence of adverse maternal and neonatal outcomes.

OBJECTIVE: The objective of this study was to determine the effect, if any, of maternal body mass index (BMI) and amniotic fluid index (AFI) on the accuracy of sonographic estimated fetal weight (EFW) at 40 to 42 weeks' gestation. METHODS: This was a retrospective cohort study of singleton gestations with ultrasound performed at 40 to 42 weeks from 2010 to 2013. In this study, patients with documented BMI and sonographic EFW and AFI, concurrently, within 7 days of delivery were included. Chronic medical conditions and fetal anomalies were excluded from this study. The primary variable of interest was the rate of substantial error in EFW, defined as absolute percentage error (APE) >10%. RESULTS: A total of 1,000 pregnancies were included. Overall, the APE was 6.0 ± 4.5% and the rate of substantial error was 17.4% (n = 174). There was no significant difference in APE or rate of substantial error between BMI groups. In the final multivariable logistic regression model, the rate of substantial error was increased in women with oligohydramnios (OR 1.79; 95% CI: 1.10-2.92). Furthermore, oligohydramnios was significantly more likely to overestimate EFW while polyhydramnios was more likely to underestimate EFW. Maternal BMI did not affect the accuracy of sonographic EFW. CONCLUSION: Sonographic EFW may be affected by extremes of AFI in the postdates period. Maternal BMI does not affect EFW accuracy at 40 to 42 weeks.

OBJECTIVES: To determine the effect, if any, of an increasing maternal body mass index (BMI) on sonographically diagnosed oligohydramnios in late gestation and how it subsequently affects obstetric and neonatal outcomes. METHODS: This retrospective cohort study evaluated all women with singleton gestations who had a sonographic examination at 40 to 42 weeks' gestational age at North Shore University Hospital from 2010 through 2013. Underweight women (prepregnancy BMI < 18.5 kg/m2 ) were excluded because of higher rates of oligohydramnios and fetal growth restriction. Patients were classified into 5 groups by late-pregnancy BMI. The primary variable of interest was the diagnosis of oligohydramnios (amniotic fluid index < 5 cm). Secondary variables of interest included the mode of delivery and indication for primary cesarean delivery. A multivariable logistic regression analysis was performed. RESULTS: Oligohydramnios was identified in 189 of 1671 patients (11.3%). There was no significant difference in the amniotic fluid index between BMI groups. The rate of primary cesarean delivery increased with each successive BMI group (P < .001) such that women in the class III obesity group had an approximately 3-fold higher rate of primary cesarean delivery than women in the normal BMI group and a 2-fold higher rate than women in the overweight BMI group. In the final multivariable logistic regression model, a high BMI, nulliparity, and excessive gestational weight gain were associated with primary cesarean delivery. However, oligohydramnios did not contribute significantly to the model. CONCLUSIONS: The maternal BMI is not associated with oligohydramnios in late gestation. An increasing maternal BMI significantly increases the risk of primary cesarean delivery.

OBJECTIVE: To determine whether women with sonographically identified uterine fibroids are at higher risk for a short cervix. METHODS: This retrospective cohort study evaluated all women with singleton gestations who had a routine second-trimester ultrasound at 17-23 weeks gestational age from 2010 to 2013. When fibroids were noted, their presence, number, location and size were recorded. Exclusion criteria included a history of cervical conization or loop electrosurgical excision procedure (LEEP), uterine anomalies, maternal age greater than 40 years, and a previously placed cerclage. The primary variable of interest was short cervix (<25 mm). Secondary variables of interest included gestational age at delivery, mode of delivery, indication for cesarean, malpresentation, birth weight, and Apgar scores. A multivariable logistic regression analysis was performed. RESULTS: Fibroids were identified in 522/10 314 patients (5.1%). In the final multivariable logistic regression model, short cervix was increased in women with fibroids (OR 2.29, 95% CI: 1.40, 3.74). The number of fibroids did not affect the frequency of short cervix. Fibroids were significantly associated with preterm delivery (<37 weeks), primary cesarean, breech presentation, lower birth weight infants, and lower Apgar scores. CONCLUSIONS: Women with uterine fibroids may be at higher risk for a short cervix. Fibroids are also associated with several adverse obstetric and neonatal outcomes.

A 26-year-old man came into the emergency department for treatment of vomiting, and pain in his abdomen and right shoulder. His vital signs were normal, with the exception of his heart rate, which was 109 bpm. His oxygen saturation was 96% on room air. The patient, a smoker, did not complain of any difficulty breathing, despite having diminished breath sounds over the left lung fields and absent breath sounds over the right. The rest of the exam was normal. The patient's initial blood work was within normal limits. We ordered a chest x-ray and a chest computed tomography (CT) scan to further assess his decreased breath sounds.
