Authors: Liu Lilly Y. , Rekawek Patricia , Cadet Julie , Stone Joanne L. 
Published: May 2019

INTRODUCTION:
The objective of this study is to identify how labor affects initiation and effectiveness of breastfeeding postpartum.

METHODS:
This is a retrospective cohort study of breastfeeding success after vaginal delivery, cesarean section after labor, and scheduled cesarean section in term, singleton deliveries in nulliparous patients at a large academic institution from 2017-2018. Breastfeeding success in the immediate postpartum period was measured by the presence of breastfeeding, the need for formula supplementation, and the neonatal percentage in weight loss over the first 2-3 days of life. This study was approved by the IRB at the Icahn School of Medicine at Mount Sinai.

RESULTS:
A total of 500 women met inclusion criteria during the study period, 339 (68%) of whom underwent spontaneous vaginal delivery (SVD), 71 (14%) of whom underwent cesarean section after labor, and 90 (18%) of whom delivered by scheduled cesarean section. Women who underwent SVD were more likely to have decreased need for formula supplementation in comparison to women who delivered via cesarean section in labor or scheduled cesarean section (57.7% vs. 75.4% and 78.5%, p<0.05), require fewer number of daily formula feedings on average (1.8+2.3 vs. 2.3+2.2 and 2.7+2.6, p<0.05), and experience a smaller percentage in neonatal weight loss over the first 2-3 days of life (4.9+2.0 vs. 7.1+2.3 and 6.4+2.8, p<0.05).

CONCLUSION:
Women who deliver by cesarean section may need more support to maintain exclusive breastfeeding postpartum than patients after vaginal delivery.

Authors: Kelly Rachel E. , Muraga Abebe H. , Howard David Leighton 
Published: May 2019

INTRODUCTION:
The primary objective was to compare the nutritional content of prescription to nonprescription prenatal vitamins.

METHODS:
We obtained samples of popular prescription and nonprescription prenatal vitamins (PNVs). We then recorded the nutritional contents of each product from the nutritional label. PNV ingredients were compared to each other and to The American College of Obstetricians and Gynecologists (ACOG) recommended guidelines. To compare physical size, we focused on PNVs in pill form. To compare cost, we used pharmacy quoted cash prices of prescription PNVs and shelf prices of nonprescription PNVs

RESULTS:
We obtained a total sample of 16 PNVs (8 prescription, 8 nonprescription). All 16 PNVs examined had at least 800 mcg of folic acid. However, no PNV, prescription or nonprescription, simultaneously met all of ACOG's nutrient recommendations for calcium, folic acid, iron, and vitamin D. In terms of size, the largest prescription PNV was approximately 1 inch in length (PrimaCare), and smallest approximately 0.6 inches (Prenate Mini, Vitafol, VitaPearl, and OB Complete). For nonprescription PNVs, the largest were also approximately 1 inch in length (Alive and Nature Made), but no nonprescription with a single pill was 0.6 inches or less. In terms of cost, the cash price of the cheapest prescription PNV was almost double that of the most expensive nonprescription PNV.

CONCLUSION:
We found no meaningful difference in nutritional adequacy of prescription versus nonprescription PNVs with respect to ACOG nutrient recommendations, despite appearance of a large cost difference.
Effect of Magnesium Sulfate on B-Type Natriuretic Peptide (BNP) Levels in Hypertensive Disease of Pregnancy [26F]
Authors: Schachter Aubrey , Lai Monica , Heard Asha J. , Hagan Joseph , Grant Joshua , Stafford Irene A. 
Published: May 2019

INTRODUCTION:
B type natriuretic peptide (BNP) is a sensitive marker discerning early cardiac dysfunction and has consistently demonstrated correlation with volume expansion and pressure overload in hypertensive disorders in pregnancy. Magnesium sulfate (MgSO4) has been shown to decrease occurrence of seizures among preeclamptic women, and some studies suggest this is mediated via a systemic vasodilatory effect. The purpose of this study is to evaluate the effect of MgSO4 on BNP values in women with severe preeclampsia.

METHODS:
Pregnant women greater than 20 weeks gestation and postpartum women up to 14 days after delivery with severe preeclampsia who presented at Touro Infirmary in New Orleans between April 2015 and May 2017 for hypertension evaluation and received MgSO4 were considered. After informed consent, BNP values were collected among 42 eligible patients before and after administration of MgSO4 for seizure prophylaxis. Data collection was performed as a retrospective chart review. Standards for preeclampsia diagnosis and management were defined by criteria described by the American College of Obstetrics and Gynecology.

RESULTS:
There was a significant reduction in BNP values after MgSO4 administration in preeclamptic women (n=42, p=0.011). The mean pre-MgSO4 BNP value was 119.6 pg/mL, and the mean post-MgSO4 BNP value was 85.2 pg/mL, for a mean decrease of 34.4 pg/mL.

CONCLUSION:
The data suggest that MgSO4 administration provides a beneficial effect on cardiac function in women with severe preeclampsia, potentially through a systemic vasodilatory and diuretic effect, reducing strain on the heart.
Maternal Plasma Lysophospholipid Acyltransferase 1 Protein Levels Correlate With Fetal Lung Maturity [31F]
Authors: Aras Siddhesh , Minchella Paige , Welch Kathryn C. , Patek Kara Danielle , Welch Robert Alan , Recanati Maurice-Andre 
Published: May 2019

INTRODUCTION:
Respiratory distress syndrome occurs in newborns not producing enough lung surfactant. This substance is predominantly comprised of phosphatidylcholine and phosphatidylglycerol. Lysophosphatidylcholine acyltransferase 1 (LPCAT1) is the enzyme responsible for their synthesis. Our group previously demonstrated that LPCAT1 mRNA in amniotic fluid and maternal plasma correlate with the amniotic fluid lamellar body count. The purpose of the present study was to determine if LPCAT1 protein levels parallel plasma LPCAT1 mRNA copy numbers. We also measured the effect of glucocorticoids and hypoxia on LPCAT1 protein expression.

METHODS:
After Institutional Review Board approval and consent, forty women from 30-40 weeks gestation and non-pregnant controls were sampled. Those with diabetes, hypertension, obesity or growth restricted were excluded. LPCAT1 mRNA levels measured by reverse transcription-polymerase chain reaction and LPCAT1 protein levels measured by enzyme linked immunosorbent assay were compared. The effect of antenatal steroids on plasma LPCAT1 was also measured. In an aligned experiment, LPCAT1 was assayed in HTR placental cells exposed to 4% hypoxia and glucocorticoids.

RESULTS:
LPCAT1 protein levels parallel mRNA copy numbers in maternal plasma. Antenatal steroids also increase maternal LPCAT1 protein levels. Both steroids and 4% hypoxia increase LPCAT1 levels in HTR placental cells in vitro.

CONCLUSION:
Discovery of a correlation between LPCAT1 protein levels and mRNA data suggests a potential noninvasive bio-marker for fetal lung maturity. HTR placental cell response to antenatal steroids and 4% hypoxia may open up new avenues in perinatal research.
Compliance to the National Comprehensive Cancer Network Guidelines for Anemia in Ovarian Cancer [36F]
Authors: Prescott Lauren S. , Mehta Sumit , Hufnagel Demetra , Ezekwe Chinyere 
Published: May 2019

INTRODUCTION:
The National Comprehensive Cancer Network (NCCN) recommends prompt evaluation and treatment of anemia. There are a paucity of studies evaluating compliance with the guidelines.

METHODS:
Retrospective cohort study of ovarian cancer patients diagnosed and treated at our institution from 2008-2018. Tumor-registry-confirmed cancer cases were identified. Patients were included if they were between the ages of 18 and 89, had their initial care at our institution, and had a hemoglobin (Hg) within the first 6 months of diagnosis.

RESULTS:
We identified 299 patients who met inclusion criteria. Median age was 62 years (interquartile range [IQR] 52-70). One hundred-eighty-five (62%) underwent primary surgery, 92 (31%) received preoperative chemotherapy, and 22 (7%) received no oncologic intervention. Of the 282 patients with a Hb identified prior to initiation of oncologic treatment, 61 (22%) patients were noted to be anemic at time of diagnosis. The median Hb at diagnosis was 12.5g/dL (IQR 11.4-13.4). Of the 299 patients in our study 269 (90%) were noted to be anemic within six months of diagnosis. Of these, 31 (12%) were noted to have grade 1, 115 (43%) grade 2, and 123 (46%) grade 3 anemia. The median Hb at nadir was 8.5g/dL (IQR 7.3-9.8). Thirty-six patients (13%) had iron studies performed. No patients had absolute iron deficiency and three had possible iron deficiency. 104 (36%) patients had treatment. Seventy-seven were transfused, 38 treated with oral iron and 3 with iv iron.

CONCLUSION:
Anemia is pervasive among ovarian cancer, but compliance with NCCN is low. There are opportunities for improvement in evaluation and management of anemia in ovarian cancer.
Is Sentinel Lymph Node Sampling Indicated in Endometrial Intraepithelial Neoplasia? [37F]
Authors: Emerson Jenna , Glassman Deanna , Quddus M. Ruhul , Mathews Cara A. 
Published: May 2019

INTRODUCTION:
We sought to identify uterine risk factors and frequency for which lymph node sampling was indicated among women undergoing hysterectomy for a preoperative diagnosis of endometrial intraepithelial neoplasia (EIN).

METHODS:
We performed a retrospective cohort study of patients undergoing hysterectomy with a preoperative diagnosis of EIN from 2016-2017. When cancer was found, the Mayo criteria (grade 1 or 2 tumor, depth of invasion <50%, and tumor size >2 cm) were used to determine if lymphadenectomy would have been indicated. Descriptive statistics were used. Approval was obtained from the institutional IRB.

RESULTS:
Fifty-three subjects were included; mean age was 60.1 years (SD: 22.9). Hysterectomy pathology was benign in 28% (n=15), EIN in 47% (n=25), and endometrioid adenocarcinoma (EC) in 25% (n=13). All cancers were FIGO Stage IA, grade 1 (n=9) or 2 (n=4). No cases had LVSI; mean depth of invasion was 3.5% (0-22%, SD 7.1%). Four cases had tumors ≥-2 cm; one of those was confined to a large polyp. Ultimately, 7.5% (n=4/53) of EIN patients met Mayo criteria; all of these were due to tumor size >2 cm. Using historical models, the risk of lymph node positivity is <5% for each of the 4 patients who met Mayo criteria. Therefore, an overall cohort of >250 patients with EIN would require sampling to identify one patient with metastatic EC.

CONCLUSION:
In an era of pre-hysterectomy sentinel nodal sampling, these findings provide new data with which to counsel patients on the potential benefits and limited yield of SLN biopsy when undergoing surgery for EIN.
AMH is a Better Predictor of Live Birth in IVF Cycles When AMH and FSH Values Are Discordant [40F]
Authors: Ligon Sarah , Lustik Michael , Levy Gary , Pier Bruce D. 
Published: May 2019

INTRODUCTION:
Follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH) assist physicians in assessing ovarian reserve during infertility evaluations and in vitro fertilization (IVF) cycles. Despite usual congruity between these biomarkers, physicians are often faced with discordant values. Our study investigates which biomarker better predicts live birth (LB) in IVF patients with discordant FSH and AMH results using the Society for Assisted Reproductive Technology Clinical Outcomes Reporting System (SART CORS) database.

METHODS:
This IRB-approved retrospective cohort study compared live birth rate (LBR) with FSH and AMH values in patients who completed at least one cycle of autologous IVF as reported to SART CORS in the years 2013 and 2015. Chi-square test was used to compare the incidence of LB among the study cohorts.

RESULTS:
44,696 patient charts met inclusion criteria. LBR was higher in patients with elevated FSH (>10mIU/mL) and normal AMH (>1 ng/dL) opposed to patients with normal FSH (<10) and low AMH (<1) (39% versus 26%, P<.001). In a multivariate logistic regression model of patients with normal FSH, low AMH had a lower risk of LB than patients with normal AMH, with relative risk of .87 (95% CI .83-.91). IVF cycle cancellation was higher in patient with normal FSH and low AMH compared to elevated FSH and normal AMH (30% versus 8%, P<.001).

CONCLUSION:
AMH is a stronger predictor of live birth in patients undergoing IVF when FSH and AMH values are discordant. Lower AMH is also associated with higher IVF cycle cancellation rates than those seen with elevated FSH values.

Authors: Linkov Faina , Shalkar Adambekov , Qi Meiyuzhen , Harris John , Mansuria Suketu M. , Edwards Robert P. 
Published: May 2019

INTRODUCTION:
Same day discharge (SDD) for minimally invasive hysterectomies is attractive to healthcare systems due to reduced costs and excellent patient outcomes. This study investigated outcome and safety data associated with the implementation of SDD protocols in a large healthcare system in Pennsylvania, UPMC, as well as to evaluate the uptake of SDD among different hospitals (tertiary care, community) and specialty types (general ob/gyn, minimally invasive gynecologic surgery (MIS), urogynecology, and gynecologic oncology).

METHODS:
Retrospectively, all medical records for hysterectomies that qualified for SDD at UPMC hospitals between 2014 (year of SDD pathway implementation) and 2017 were identified. We evaluated trends in health care outcomes (complications, return visits, and readmissions) by year using Cochrane Armitage test for trend. University of Pittsburgh IRB approved this work.

RESULTS:
5575 cases of women qualified for SDD have been evaluated. For minimally invasive hysterectomies, the rate of SDD went from 29% in 2014 to 75% in 2017 (ptrend <0.0001). The rate of complications decreased over time (ptrend <0.0001). Overall LOS (length of stay in minutes) decreased over time. SDD implementation was not associated with an increase in readmissions and return visits. All specialty types adopted the program over the years, with the degree of adoption varying among specialty types (MIS having the highest degree of adoption).

CONCLUSION:
Implementing a SDD program for hysterectomy within a large heterogeneous health care system can occur rapidly across all sizes of hospitals and among different subspecialists. At UPMC, this program resulted in decreased LOS without increase in complications.
The Cost of Elective Labor Induction in The MFMU ARRIVE Trial [19OP]
Authors: Einerson Brett D. 
Published: May 2019

INTRODUCTION:
The ARRIVE trial compared labor induction to expectant management in nulliparas at term. We measured the relative costs.

METHODS:
A cost evaluation of all 1,230 Utah participants enrolled in ARRIVE from antenatal randomization to 6 weeks after delivery. Actual costs were measured using advanced analytics and time-derived activity-based costing at two Utah tertiary healthcare systems involved in the trial. The primary outcome was total cost associated with maternal and neonatal care. Cost outcomes were compared in each arm using generalized linear models, controlling for differences in cost between systems. Costs were normalized and presented as the relative cost in the induction arm vs expectant management arm.

RESULTS:
Total costs were similar between arms: +3.7% (95% CI -3.0% - +10.8%). Neonatal costs were similar: -1.5% (95% CI -16.9% - +16.8%). Costs associated with maternal care were 7.3% higher in the induction arm (95% CI +2.3% - +12.5%). Total costs and neonatal costs did not differ between arms when stratified by advanced maternal age, obesity, unfavorable cervix, or need for ripening. In obese women, maternal costs were 9.7% higher in the induction arm (95% CI +1.4% - +18.6%). In women with an unfavorable cervix (Bishop score less than 5), maternal costs were 10.6% higher in the induction arm (95% CI +3.3% - +18.5%). The relative cost of induction was similar at both health systems despite different costing methodologies.

CONCLUSION:
The cost of elective labor induction at term was similar to expectant management.
State Based Perinatal Quality Collaborative Pilot-Statewide Reduction of Colorado Primary Cesarean Delivery Rate [04OP]
Authors: Donnelly Meghan Ann , Peterson Anne , Fennimore Robin MacColl , Schneider Emily Nicole , Griffith Nancy 
Published: May 2019

INTRODUCTION:
The Colorado Perinatal Care Quality Collaborative performed a pilot quality improvement project to increase adherence to guidelines from the Consensus for the Prevention of the Primary Cesarean Delivery in a statewide cohort of hospitals to safely reduce their nulliparous, term, singleton, vertex (NTSV) cesarean delivery (CD) rate.

METHODS:
This quality improvement initiative was performed at 6 community hospitals across Colorado. Pre (January 2017 to May 2018) and post intervention (June to Oct 2018) NTSV CD and composite maternal and neonatal morbidity rates were determined for each hospital and the overall cohort using Colorado State Vital Statistics data. Interventions included distributing institution and provider specific NTSV CD rates, education for providers and nurses, implementation of a pre-cesarean labor dystocia checklist, and convening two forums for collaboration between hospitals. NTSV CD and composite maternal and neonatal morbidity rates were compared before and after the interventions for each hospital and the cohort.

RESULTS:
The 6 participating hospitals perform 19% of live births in Colorado. Pre-intervention hospital NTSV CD rates ranged from 19.3% to 33.8%. The cohort pre-intervention NTSV CD rate was 24.6%, and decreased to 21.9% post-intervention (P=0.04, 95% CI 0.77-0.99). There was no significant increase in composite maternal or neonatal morbidity post-intervention (8.6% vs 7.1% and 7.1% vs 6.8% respectively).

CONCLUSION:
A quality improvement effort led by a state-based Perinatal Quality Collaborative was effective at safely reducing NTSV CD rates across multiple hospitals. Future efforts will aim at expanding the number of participating hospitals and sustainability.
Estetrol Combined with Drospirenone: A New Oral Contraceptive With a Favorable Hemostatic Profile [20OP]
Authors: Creinin Mitchell D. , Rosing Jan , Jost Maud , Kinet Virginie , Chatel Guillaume , Foidart Jean Michel 
Published: May 2019

INTRODUCTION:
Estetrol (E4) is a natural human estrogen with selective action in different tissues. A combined oral contraceptive (COC) with E4 15 mg and Drospirenone (DRSP) 3mg is in Phase 3 trials. Here, we report its effects on hemostatic markers.

METHODS:
In this IRB-approved, randomized, open-label study, women received E4 15 mg/DRSP 3mg (n=38), ethinyl-estradiol (EE) 30 mcg/Levonorgestrel-(LNG) 150 mcg (n=29) or EE-20 mcg/DRSP-3 mg (n=31). We compared changes of hemostasis parameters between baseline and cycle 6 with a P<.05 considered significant.

RESULTS:
Pro-coagulant factors increased similarly in E4/DRSP, EE/LNG and EE/DRSP users for fibrinogen (+10%, +5% and +16%, respectively) and prothrombin (+7%, +13% and +7%, respectively). Anti-coagulant factors decreased significantly less with E4/DRSP and EE/LNG compared to EE/DRSP for Protein S activity (-4%, -5% and -30%, respectively) and free Protein S antigen (+5%, -3%; and -23%, respectively). The fibrinolysis marker, tissue-plasminogen activator, changed significantly more favorably with E4/DRSP than EE/LNG or EE/DRSP (-7%, -33% and -40%, respectively). Prothrombin fragment 1+2, a marker of ongoing coagulation, changed significantly less with E4/DRSP than other COCs (+23%, +71% and +64%, respectively). Endogenous thrombin potential (ETP) activated protein C resistance (APCr) increased significantly with EE/LNG (+78%) and EE/DRSP (+121%) compared to E4/DRSP (+3.0).

CONCLUSION:
Coagulation parameter changes over 6 months demonstrate mostly similar changes for E4/DRSP and EE/LNG, both of which are less thrombogenic than EE/DRSP. For some factors, primarily anticoagulant and fibrinolysis markers, ETP-APCr, and prothrombin fragment 1+2, E4/DRSP is more favorable than EE/LNG. The differences between E4/DRSP and EE/DRSP demonstrate that the choice of estrogen is important when considering thrombosis risk.
SECOND PLACE Therapeutic Hypothermia in Severe Hypoxic-Ischemic Encephalopathy: A Cost-Effectiveness Analysis [23OP]
Authors: Packer Claire , Hersh Alyssa R. , Sargent James Andrew , Caughey Aaron B. 
Published: May 2019

INTRODUCTION:
Previous literature has demonstrated that therapeutic hypothermia (cooling) begun within six hours of life decreases neonatal mortality and long-term neurodevelopmental disability (NDD) in neonates with hypoxic-ischemic encephalopathy (HIE). We sought to investigate whether such an intervention is cost-effective in cases of severe HIE.

METHODS:
A TreeAge decision analytic model was designed comparing cooling vs. no cooling in a cohort of 10,000 term neonates with HIE. Rates of death and NDD were estimated from a Cochrane meta-analysis. Costs were derived from the literature. Utilities were applied to discounted life expectancy to generate quality-adjusted life years (QALYs). All costs and QALYs were discounted at an annual rate of 3% with a cost-effectiveness threshold of $100,000 per QALY. Sensitivity analyses were conducted to assess the robustness of these results.

RESULTS:
Cooling for the management of severe HIE resulted in increased costs and higher QALYs, with an incremental cost-effectiveness ratio (ICER) of $4,366/QALY. Cooling resulted in 1,600 fewer neonatal deaths, but even with a lower rate of NDD in the survivors, there were 100 additional cases with cooling. In univariate sensitivity analysis, when varying the probability of a healthy child with cooling, cooling was found to be the cost-effective strategy across all ranges and the dominant (lower costs, higher QALYs) strategy above 0.675.

CONCLUSION:
Therapeutic hypothermia is the cost-effective intervention with improved outcomes for neonates with severe perinatal HIE over a wide range of assumptions. Despite the increased cost, more neonates survive morbidity free when compared with standard care.
Sonographic Measurement of the Inferior Vena Cava (IVC) to Assess Postpartum Hypovolemia: A Pilot Study [35S]
Authors: Spiegel Tirtza Nechama 
Published: May 2019

INTRODUCTION:
Increased respiratory variation in IVC diameter is used to detect hypovolemia in critical care settings, including early warning of excessive perioperative blood loss. One study examined the relationship between IVC diameter and postpartum hemorrhage, in a cohort of women after vaginal delivery. We aimed to evaluate if respiratory variation in IVC diameter after cesarean delivery was associated with intraoperative hemorrhage or postoperative complications from hypovolemia.

METHODS:
The difference in IVC diameter between inspiration and expiration was measured sonographically in the supine position, 1-2 hours after cesarean delivery. Demographic and delivery data were collected. We hypothesized that respiratory variation would be increased in patients with complications related to hypovolemia

RESULTS:
4/26 patients (15.3%) had postoperative complications from hypovolemia (oliguria and/or hemorrhage). Their mean IVC diameter variation was 2.9 mm compared with 4.4 mm in the uncomplicated group. Mean respiratory diameter variation was 2.2 mm for patients with intraoperative blood loss >1,000 ml versus 4.6 cm for patients with â‰¤ 1,000 ml blood loss.

CONCLUSION:
Contrary to our hypothesis, respiratory variation in IVC diameter was not increased in patients with postoperative complications from hypovolemia or intraoperative hemorrhage. A larger patient sample is needed before determining the utility of this technique. Our preliminary findings may reflect aggressive intraoperative fluid resuscitation in patients with excessive blood loss.
