Impact of prenatally diagnosed congenital heart defects on outcomes and management.

Fetal echocardiogram aids in prenatal identification of neonates at high risk for congenital heart defects (CHD). Prenatal detection rates for CHD have increased with improved ultrasound technology, the use of the early fetal echocardiography, and standardization of the performance of the fetal echocardiogram. Accurate prenatal detection of CHD, particularly complex CHD, is an important contributor to improved survival rates for patients with CHD. Early detection allows for families to choose whether or not to continue with pregnancy, referral to pediatric cardiology specialists for patient education, and delivery planning. Better psychosocial supports are needed for families with CHD.

Association of adverse perinatal outcomes of intrahepatic cholestasis of pregnancy with biochemical markers: results of aggregate and individual patient data meta-analyses.

BACKGROUND: Intrahepatic cholestasis of pregnancy is associated with adverse perinatal outcomes, but the association with the concentration of specific biochemical markers is unclear. We aimed to quantify the adverse perinatal effects of intrahepatic cholestasis of pregnancy in women with increased serum bile acid concentrations and determine whether elevated bile acid concentrations were associated with the risk of stillbirth and preterm birth. METHODS: We did a systematic review by searching PubMed, Web of Science, and Embase databases for studies published from database inception to June 1, 2018, reporting perinatal outcomes for women with intrahepatic cholestasis of pregnancy when serum bile acid concentrations were available. Inclusion criteria were studies defining intrahepatic cholestasis of pregnancy based upon pruritus and elevated serum bile acid concentrations, with or without raised liver aminotransferase concentrations. Eligible studies were case-control, cohort, and population-based studies, and randomised controlled trials, with at least 30 participants, and that reported bile acid concentrations and perinatal outcomes. Studies at potential higher risk of reporter bias were excluded, including case reports, studies not comprising cohorts, or successive cases seen in a unit; we also excluded studies with high risk of bias from groups selected (eg, a subgroup of babies with poor outcomes were explicitly excluded), conference abstracts, and Letters to the Editor without clear peer review. We also included unpublished data from two UK hospitals. We did a random effects meta-analysis to determine risk of adverse perinatal outcomes. Aggregate data for maternal and perinatal outcomes were extracted from case-control studies, and individual patient data (IPD) were requested from study authors for all types of study (as no control group was required for the IPD analysis) to assess associations between biochemical markers and adverse outcomes using logistic and stepwise logistic regression. This study is registered with PROSPERO, number CRD42017069134. FINDINGS: We assessed 109 full-text articles, of which 23 studies were eligible for the aggregate data meta-analysis (5557 intrahepatic cholestasis of pregnancy cases and 165 136 controls), and 27 provided IPD (5269 intrahepatic cholestasis of pregnancy cases). Stillbirth occurred in 45 (0·83%) of 4936 intrahepatic cholestasis of pregnancy cases and 519 (0·32%) of 163 947 control pregnancies (odds ratio [OR] 1·46 [95% CI 0·73-2·89]; I2=59·8%). In singleton pregnancies, stillbirth was associated with maximum total bile acid concentration (area under the receiver operating characteristic curve [ROC AUC]) 0·83 [95% CI 0·74-0·92]), but not alanine aminotransferase (ROC AUC 0·46 [0·35-0·57]). For singleton pregnancies, the prevalence of stillbirth was three (0·13%; 95% CI 0·02-0·38) of 2310 intrahepatic cholestasis of pregnancy cases in women with serum total bile acids of less than 40 µmol/L versus four (0·28%; 0·08-0·72) of 1412 cases with total bile acids of 40-99 µmol/L (hazard ratio [HR] 2·35 [95% CI 0·52-10·50]; p=0·26), and versus 18 (3·44%; 2·05-5·37) of 524 cases for bile acids of 100 µmol/L or more (HR 30·50 [8·83-105·30]; p<0·0001). INTERPRETATION: The risk of stillbirth is increased in women with intrahepatic cholestasis of pregnancy and singleton pregnancies when serum bile acids concentrations are of 100 µmol/L or more. Because most women with intrahepatic cholestasis of pregnancy have bile acids below this concentration, they can probably be reassured that the risk of stillbirth is similar to that of pregnant women in the general population, provided repeat bile acid testing is done until delivery.

A randomized trial of Foley balloon induction of labor trial in nulliparas (FIAT-N).

BACKGROUND: With an increasing rate of induction of labor, it is important to choose induction methods that are safe and efficient in achieving a vaginal delivery. The optimal method for inducing nulliparous women with an unfavorable cervix is not known. OBJECTIVE: We sought to determine if induction of labor with simultaneous use of oxytocin and Foley balloon vs sequential use of Foley balloon followed by oxytocin decreases the time to delivery in nulliparous women. STUDY DESIGN: We conducted a randomized controlled trial of nulliparous women presenting for induction at a single institution from December 2013 through March 2015. After decision for induction was made by their primary provider, women with gestational age ≥24 weeks with a nonanomalous, singleton fetus in vertex presentation with intact membranes were offered participation. Exclusion criteria included history of uterine surgery, unexplained vaginal bleeding, latex allergy, or contraindication to vaginal delivery. Participants were randomized to either simultaneous (oxytocin and Foley balloon) or sequential (oxytocin after expulsion of Foley balloon) induction group. The primary outcome was time from induction to delivery. Secondary outcomes included mode of delivery, estimated blood loss, postpartum hemorrhage, chorioamnionitis, and composite neonatal outcome. Maternal and neonatal outcomes were collected via chart review. Analyses were done on an intention-to-treat basis. RESULTS: A total of 166 patients were enrolled; 82 in the simultaneous and 84 in the sequential group. There were no differences in baseline characteristics in the 2 groups. Patients who received simultaneous oxytocin with insertion of a Foley balloon delivered significantly earlier (15.92 vs 18.87 hours, P = .004) than those in the sequential group. There was no difference in rate of cesarean delivery, estimated blood loss, postpartum hemorrhage, chorioamnionitis, or composite neonatal outcome. CONCLUSION: Simultaneous use of oxytocin and Foley balloon for induction of labor results in a significantly shorter interval to delivery in nulliparas.

Higher-order Multiples.

Higher-order multiple gestations have increased since the advent of advanced reproductive technologies. These pregnancies present unique risks to both mothers and fetuses. It is imperative that early diagnosis of chronicity be determined and that proper counseling is performed, so patients understand the risks, evaluation, and management needed.

Periviability for the Ob-Gyn Hospitalist.

Periviable birth refers to births occurring between 20 0/7 and 25 6/7 weeks gestational age. Management of pregnant people and neonates during this fragile time depends on the clinical status, as well as the patient's wishes. Providers should be prepared to counsel patients at the cusp of viability, being mindful of the uncertainty of outcomes for these neonates. While it is important to incorporate the data on projected morbidity and mortality into one's counseling, shared-decision making is most essential to caring for these patients and optimizing outcomes for all.

Rate of clinically significant red blood cell antibody seroconversion in pregnancy.

OBJECTIVE: To determine the rate of clinically significant red blood cell (RBC) antibody seroconversion in pregnancy and associated risk factors and neonatal outcomes. METHODS: This is a retrospective cohort study of all deliveries within a large multi-hospital system from July 2016 to March 2023. Deliveries with a missing RBC antibody screen on admission for delivery were excluded, as were deliveries with a positive antibody screen on admission for delivery without a record of antecedent type and screen (T&S) in that pregnancy. Deliveries were categorized as 1) not possessing clinically significant antibodies (which includes those with a negative antibody screen, evidence of passive immunity solely due to Rh(D) immune globulin (RhIG), or possessing only non-clinically significant RBC antibodies); 2) previously alloimmunized (i.e. pregnancies that demonstrated clinically significant antibodies on the first T&S, regardless if they accrued additional antibodies throughout the pregnancy); or 3) seroconverted (i.e. no clinically significant antibodies on the first T&S with subsequent development of alloimmunization with clinically significant antibodies). For neonates born to seroconverted patients with clinically significant antibodies, neonatal outcomes such as initial hemoglobin, need for transfusion, and neonatal intensive care unit (NICU) admission were ascertained via chart abstraction. All records were linked with an existing validated database, inclusive of maternal characteristics and pregnancy outcomes, and comparisons were made between three categories based on antibody status with a sub-analysis of two categories. Bivariate analysis was performed with Chi-square for categorical and Wilcoxon rank-sum or Kruskal-Wallis test for continuous variables. RESULTS: There were 58,912 pregnant individuals with 71,384 eligible deliveries during the study period, with 67,570 deliveries remaining after data linkage. Of these, 67,209 (99.5%) deliveries had a negative or non-clinically significant antibody screen at delivery. Of the remaining 361 (0.53%) deliveries, 185 (0.27%) were previously alloimmunized and 176 (0.26%) seroconverted in pregnancy. Among pregnancies demonstrating seroconversion, the most common newly acquired antibodies were anti-E, anti-c, anti-JkA, anti-C, anti-D, anti-M, anti-K, and anti-S. Among the 176 pregnancies complicated by seroconversion, there were four unexplained fetal losses, none of which were attributable to HDFN. Among the 178 liveborn neonates born to the 176 pregnancies demonstrating seroconversion, three (1.7%) infants had initial hemoglobin <13.5 mg/dL, four (2.2%) required postnatal transfusion but all were unrelated to HDFN, and 34 (19.1%) required NICU admission. When comparing deliveries demonstrating seroconversion with those with a negative antibody screen at delivery, advanced maternal age and increasing gravidity and parity were most strongly associated with seroconversion. CONCLUSION: Development of new clinically significant RBC antibodies in pregnancy occurred at a rate of 0.26% in this large cohort study with no cases of stillbirth or neonatal demise attributable to RBC alloimmunization among pregnancies demonstrating seroconversion. Advanced maternal age and increasing gravidity and parity were most strongly associated with seroconversion in pregnancy. Routine third trimester prenatal assessment of maternal antibody status may not be indicated due to low likelihood for clinically significant seroconversion.

Differences in Person-Centered Care in Fetal Care Centers: Results from the U.S. Pilot Study of the PCC-FCC Scale.

OBJECTIVE: We report findings from a U.S. mixed-methods pilot study of the Person-Centered Care in Fetal Care Centers (PCC-FCC) Scale. METHODS: Participants, who received care at a U.S. Fetal Care Center (FCC) between 2017 and 2021, completed an online questionnaire providing sociodemographic details, specifics about the care received, qualitative experiences, and scores from the PCC-FCC Scale. RESULTS: Participants' (n = 247) PCC-FCC scores and qualitative feedback indicate high perceived person-centered care (PCC), particularly in areas of care coordination, respectful care, and patient education. However, 8% scored below the midpoint, and 38% of comments were negative, especially regarding expectation setting, preparation for post-intervention maternal health, and psychosocial support. Public insurance was associated with higher total PCC-FCC (p = 0.03) and Factor 2 scores (p = 0.02) compared to those with private insurance. The qualitative themes trust, clarity, comprehensive care, compassion, and belonging further elucidate the concept of PCC in FCCs. CONCLUSION: The PCC-FCC Scale pilot study revealed strong overall PCC in FCCs, yet variability in patient experiences suggests areas needing improvement, including expectation setting, preparation for post-intervention maternal health, and psychosocial support. Future research must prioritize diverse samples and continued mixed methodologies to better understand the role of insurance and identify other potential disparities, ensuring comprehensive representation of the FCC patient population.

The Role of Social Determinants in Diagnosis Timing for Fetal Care Center-Eligible Conditions: A Scoping Review.

Timely identification of fetal conditions enables comprehensive evaluation, counseling, postnatal planning, and prenatal treatments. This study assessed the existing evidence on how social determinants of health (SDOH) influence diagnosis timing of fetal conditions appropriate for care in fetal care centers (FCCs). Eligible studies were conducted in the U.S. and published in English after 1999. We employed the Healthy People 2020 SDOH framework to categorize and analyze data from 16 studies, where 86% focused solely on congenital heart disease (CHD). Studies primarily focused on individual-level SDOH, with only 36% addressing structural-level factors. A total of 31 distinct indicators of SDOH were identified, with 68% being unique to individual studies. Indicators often varied in definition and specificity. Three studies covered all five SDOH categories in the Healthy People 2020 Framework. Studies revealed varying and often conflicting associations with SDOH indicators, with race and ethnicity being the most explored (100%), followed by socioeconomic status (69%), maternal age (57%), residence (43%), and structural factors (29%). Our findings highlight the need for more comprehensive research, including conditions beyond CHD, and the establishment of consensus on indicators of SDOH. Such efforts are necessary to gain a deeper understanding of the underlying factors driving disparities in fetal diagnosis and treatment.

Prospective Evaluation of High Titer Autoantibodies and Fetal Home Monitoring in the Detection of Atrioventricular Block Among Anti-SSA/Ro Pregnancies.

OBJECTIVE: This prospective study of pregnant patients, Surveillance To Prevent AV Block Likely to Occur Quickly (STOP BLOQ), addresses the impact of anti-SSA/Ro titers and utility of ambulatory monitoring in the detection of fetal second-degree atrioventricular block (AVB). METHODS: Women with anti-SSA/Ro autoantibodies by commercial testing were stratified into high and low anti-52-kD and/or 60-kD SSA/Ro titers applying at-risk thresholds defined by previous evaluation of AVB pregnancies. The high-titer group performed fetal heart rate and rhythm monitoring (FHRM) thrice daily and weekly/biweekly echocardiography from 17-26 weeks. Abnormal FHRM prompted urgent echocardiography to identify AVB. RESULTS: Anti-52-kD and/or 60-kD SSA/Ro met thresholds for monitoring in 261 of 413 participants (63%); for those, AVB frequency was 3.8%. No cases occurred with low titers. The incidence of AVB increased with higher levels, reaching 7.7% for those in the top quartile for anti-60-kD SSA/Ro, which increased to 27.3% in those with a previous child who had AVB. Based on levels from 15 participants with paired samples from both an AVB and a non-AVB pregnancy, healthy pregnancies were not explained by decreased titers. FHRM was considered abnormal in 45 of 30,920 recordings, 10 confirmed AVB by urgent echocardiogram, 7 being second-degree AVB, all <12 hours from normal FHRM and within another 0.75 to 4 hours to echocardiogram. The one participant with second/third-degree and two participants with third-degree AVB were diagnosed by urgent echocardiogram >17 to 72 hours from an FHRM. Surveillance echocardiograms detected no AVB when the preceding interval FHRM recordings were normal. CONCLUSION: High-titer antibodies are associated with an increased incidence of AVB. Anti-SSA/Ro titers remain stable over time and do not explain the discordant recurrence rates, suggesting that other factors are required. Fetal heart rate and rhythm (FHRM) with results confirmed by a pediatric cardiologist reliably detects conduction abnormalities, which may reduce the need for serial echocardiograms.

Persistence of placenta previa in twin gestations based on gestational age at sonographic detection.

OBJECTIVES: The purpose of this study was to evaluate the gestational age at sonographic detection of placenta previa as a predictor of previa persistence until delivery in twin gestations. METHODS: A retrospective cohort of twin pregnancies with placenta previa in a single ultrasound unit was analyzed from 2005 to 2010. Pregnancies were ascertained from a database. Diagnoses were confirmed by transvaginal imaging. Previa was categorized as complete if the placenta completely covered the internal os or marginal if the inferior placental edge reached within 2 cm. Gestational ages were grouped into intervals from 15 to 35 weeks. The study outcome was placenta previa at delivery. Only twin pregnancies at 25 weeks' gestation and later were analyzed using nonparametric statistics as appropriate, with P < .05 as significant. RESULTS: Placenta previa was detected in 120 twin pregnancies in the second trimester: 32 complete and 88 marginal. Of those with placenta previa at 15 to 19, 20 to 23, 24 to 27, 28 to 31, and 32 to 35 weeks, previa persisted until delivery in 8.3%, 19.2%, 50%, 75%, and 92.5%, respectively. Only at 15- to 19- and 20- to 23-week intervals was complete previa more likely to persist than marginal previa (P < .001). CONCLUSIONS: The likelihood of placenta previa persistence in twins is dependent on the gestational age at sonographic detection. Only at earlier gestations does the type of previa affect its persistence. As gestational age advances, the likelihood of resolution of placenta previa diminishes regardless of the type noted.

Ultrasound Image Quality Comparison Between a Handheld Ultrasound Transducer and Mid-Range Ultrasound Machine.

Objectives: Not all labor and delivery floors are equipped with ultrasound machines which can serve the needs of both obstetricians and anesthesiologists. This cross-sectional, blinded, randomized observational study compares the image resolution (RES), detail (DET), and quality (IQ) acquired by a handheld ultrasound, the Butterfly iQ, and a mid-range mobile device, the Sonosite M-turbo US (SU), to evaluate their use as a shared resource. Methods: Seventy-four pairs of ultrasound images were obtained for different imaging purposes: 29 for spine (Sp), 15 for transversus abdominis plane (TAP) and 30 for diagnostic obstetrics (OB) purposes. Each location was scanned by both the handheld and mid-range machine, resulting in 148 images. The images were graded by three blinded experienced sonographers on a 10-point Likert scale. Results: The mean difference for Sp imaging favored the handheld device (RES: -0.6 [(95% CI -1.1, -0.1), p = 0.017], DET: -0.8 [(95% CI -1.2, -0.3), p = 0.001] and IQ: -0.9 [95% CI-1.3, -0.4, p = 0.001]). For the TAP images, there was no statistical difference in RES or IQ, but DET was favored in the handheld device (-0.8 [(95% CI-1.2, -0.5), p < 0.001]). For OB images, the SU was favored over the handheld device with RES, DET and IQ with mean differences of 1.7 [(95% CI 1.2, 2.1), p < 0.001], 1.6 [(95% CI 1.2, 2.0], p < 0.001] and 1.1 [(95% CI 0.7, 1.5]), p < 0.001), respectively. Conclusions: Where resources are limited, a handheld ultrasound may be considered as a potential low-cost alternative to a more expensive ultrasound machine for point of care ultrasonography, better suited to anesthetic vs. diagnostic obstetrical indications.

Ursodeoxycholic acid in intrahepatic cholestasis of pregnancy: a systematic review and individual participant data meta-analysis.

BACKGROUND: Ursodeoxycholic acid is commonly used to treat intrahepatic cholestasis of pregnancy, yet its largest trial detected minimal benefit for a composite outcome (stillbirth, preterm birth, and neonatal unit admission). We aimed to examine whether ursodeoxycholic acid affects specific adverse perinatal outcomes. METHODS: In this systematic review and individual participant data meta-analysis, we searched PubMed, Web of Science, Embase, MEDLINE, CINAHL, Global Health, MIDIRS, and Cochrane without language restrictions for relevant articles published between database inception, and Jan 1, 2020, using search terms referencing intrahepatic cholestasis of pregnancy, ursodeoxycholic acid, and perinatal outcomes. Eligible studies had 30 or more study participants and reported on at least one individual with intrahepatic cholestasis of pregnancy and bile acid concentrations of 40 µmol/L or more. We also included two unpublished cohort studies. Individual participant data were collected from the authors of selected studies. The primary outcome was the prevalence of stillbirth, for which we anticipated there would be insufficient data to achieve statistical power. Therefore, we included a composite of stillbirth and preterm birth as a main secondary outcome. A mixed-effects meta-analysis was done using multi-level modelling and adjusting for bile acid concentration, parity, and multifetal pregnancy. Individual participant data analyses were done for all studies and in different subgroups, which were produced by limiting analyses to randomised controlled trials only, singleton pregnancies only, or two-arm studies only. This study is registered with PROSPERO, CRD42019131495. FINDINGS: The authors of the 85 studies fulfilling our inclusion criteria were contacted. Individual participant data from 6974 women in 34 studies were included in the meta-analysis, of whom 4726 (67·8%) took ursodeoxycholic acid. Stillbirth occurred in 35 (0·7%) of 5097 fetuses among women with intrahepatic cholestasis of pregnancy treated with ursodeoxycholic acid and in 12 (0·6%) of 2038 fetuses among women with intrahepatic cholestasis of pregnancy not treated with ursodeoxycholic acid (adjusted odds ratio [aOR] 1·04, 95% CI 0·35-3·07; p=0·95). Ursodeoxycholic acid treatment also had no effect on the prevalence of stillbirth when considering only randomised controlled trials (aOR 0·29, 95% CI 0·04-2·42; p=0·25). Ursodeoxycholic acid treatment had no effect on the prevalence of the composite outcome in all studies (aOR 1·28, 95% CI 0·86-1·91; p=0·22), but was associated with a reduced composite outcome when considering only randomised controlled trials (0·60, 0·39-0·91; p=0·016). INTERPRETATION: Ursodeoxycholic acid treatment had no significant effect on the prevalence of stillbirth in women with intrahepatic cholestasis of pregnancy, but our analysis was probably limited by the low overall event rate. However, when considering only randomised controlled trials, ursodeoxycholic acid was associated with a reduction in stillbirth in combination with preterm birth, providing evidence for the clinical benefit of antenatal ursodeoxycholic acid treatment.

Coronavirus disease 2019 pregnancy outcomes in a racially and ethnically diverse population.

Background: Older age and medical comorbidities are identified risk factors for developing severe coronavirus disease 2019. However, there are limited data on risk stratification, clinical and laboratory course, and optimal management of coronavirus disease 2019 in pregnancy. Objective: Our study aimed to describe the clinical course of coronavirus disease 2019, effect of comorbidities on disease severity, laboratory trends, and pregnancy outcomes of symptomatic and asymptomatic severe acute respiratory syndrome coronavirus 2-positive pregnant women. Study Design: This is a case series of pregnant and postpartum women who received positive test results for severe acute respiratory syndrome coronavirus 2 between March 3, 2020, and May 11, 2020, within 3 hospitals of the Yale New Haven Health delivery network. Charts were reviewed for basic sociodemographic and prepregnancy characteristics, coronavirus disease 2019 course, laboratory values, and pregnancy outcomes. Results: Of the 1567 tested pregnant and postpartum women between March 3, 2020, and May 11, 2020, 9% (n=141) had a positive severe acute respiratory syndrome coronavirus 2 result. Hispanic women were overrepresented in the severe acute respiratory syndrome coronavirus 2-positive group (n=61; 43.8%). In addition, Hispanic ethnicity was associated with a higher rate of moderate and severe diseases than non-Hispanic (18% [11/61] vs 3.8% [3/78], respectively; odds ratio, 5.5; 95% confidence interval, 1.46-20.7; P=.01). Of note, 44 women (31.2%) were asymptomatic, 37 of whom (26.2%) were diagnosed on universal screening upon admission for delivery. Moreover, 59% (n=83) were diagnosed before delivery, 36% (n=51) upon presentation for childbirth, and 5% (n=7) after delivery. Severe disease was diagnosed in 6 cases (4.3%), and there was 1 maternal death. Obese women were more likely to develop moderate and severe diseases than nonobese women (16.4% [9/55] vs 3.8% [3/79]; odds ratio, 4.96; 95% confidence interval, 1.28-19.25; P=.02). Hypertensive disorders of pregnancy were diagnosed in 22.3% of women (17/77) who delivered after 20 weeks' gestation. Higher levels of C-reactive protein during antepartum coronavirus disease 2019-related admission were more common in women with worse clinical course; however, this association did not reach statistical significance. Conclusion: Coronavirus disease 2019 in pregnancy may result in severe disease and death. Hispanic women were more likely to receive a positive test result for severe acute respiratory syndrome 2 than other ethnic groups. Obesity and Hispanic ethnicity represent risk factors for moderate and severe diseases.

Cesarean Scar Pregnancy, Incidence, and Recurrence: Five-Year Experience at a Single Tertiary Care Referral Center.

OBJECTIVE: To describe the treatment and subsequent pregnancy outcomes in patients with cesarean scar pregnancies at a single institution over 5 years. METHODS: This is a case series of all cesarean scar pregnancies diagnosed from May 2013 to March 2018 at Yale-New Haven Hospital. Data were collected on each patient using electronic medical record review and included patient demographics; medical, surgical, and obstetric history; pregnancy characteristics; treatment modalities used; response to therapy; complications; and subsequent pregnancy outcomes. RESULTS: Thirty cases of cesarean scar pregnancies were diagnosed in 26 patients, including one recurrence in one patient and three recurrences in another. Forty-six percent of cesarean scar pregnancies were in Hispanic women. The median number of prior cesarean deliveries was two. Mean gestational age at the time of diagnosis was 46 days (SD±10). Fetal cardiac activity was detected in 18 cases. Three patients initially were erroneously diagnosed with a viable intrauterine pregnancy and failed medical termination. Others opted for termination through systemic methotrexate alone (n=4), systemic and local methotrexate (n=12), systemic and local methotrexate with potassium chloride injected into the gestational sac (n=3), potassium chloride injection with laparotomy and wedge resection (n=1), methotrexate with bilateral uterine artery embolization (n=2), or intrauterine balloon (n=4). Five patients who underwent expectant management or methotrexate therapy had retained products of conception and required hysteroscopy and curettage. One patient opted for hysterectomy after failed curettage. After complete resolution of cesarean scar pregnancies, there were 10 subsequent spontaneous conceptions in eight patients, including four recurrent cesarean scar pregnancies, four term pregnancies, and one spontaneous abortion. One viable normally located pregnancy is ongoing. CONCLUSION: There is a wide array of treatment modalities available for cesarean scar pregnancies. Women with a cesarean scar pregnancy are at risk for its recurrence in the future, although normal pregnancy after a cesarean scar pregnancy is also possible. Safe outcomes depend on timely diagnosis and multidisciplinary care by skilled clinicians.

A Novel Approach to Serial Amnioinfusion in a Case of Premature Rupture of Membranes Near the Limit of Viability.

Prelabor rupture of the membranes (PROM) near the limit of viability is associated with significant risks for both mother and fetus. Preterm labor, intra-amniotic infection, and placental abruption are the immediate risks to the pregnancy; however, the fetus incurs additional risks related to the sequela of persistent oligohydramnios. Transabdominal intra-amniotic infusions have been studied. Results, suggesting that this intervention may prolong the latency period, and potentially, decrease pulmonary hypoplasia in surviving neonates without evidence of increasing risk of intra-amniotic infection. To our knowledge, the use of antibiotic-infused fluid has not been reported in this clinical scenario. Therefore, we present a case of a patient with PROM before the limit of viability who underwent serial transabdominal amnioinfusions with oxacillin-containing normal saline, which resulted in membrane resealing and neonatal survival with no additional maternal morbidity.

Outcome after implementation of a modern management strategy for intrahepatic cholestasis of pregnancy.

OBJECTIVE: The aim of this study was to determine whether the institution of a modern management strategy affected pregnancy outcomes for intrahepatic cholestasis of pregnancy (ICP). METHODS: We performed a retrospective cohort study of women diagnosed with ICP at one hospital from 2005 to 2013. A new management protocol for ICP was instituted in 2009 for women with total bile acids >40 µmol/L at <36 weeks. This strategy included inpatient admission, continuous fetal heart rate monitoring, with delivery between 36 and 37 weeks. We compared maternal and neonatal outcomes prior and subsequent to the institution of this protocol. RESULTS: We identified 186 singleton gestations with bile acids >40 µmol/L and diagnosis <36 weeks. Patient demographics were similar between the groups, with the exception of greater maternal age and gestational diabetes in the newer cohort. The newer cohort demonstrated a significant reduction in the incidence of stillbirth 0% versus 3.4%, p= 0.035). There was no difference in the age at delivery, cesarean delivery rates or NICU admissions. CONCLUSION: Application of our management strategy for ICP reduced the stillbirth rate without adversely affecting other maternal and neonatal outcomes.

Mitochondrial gene expression profiles are associated with intrahepatic cholestasis of pregnancy.

INTRODUCTION: Intrahepatic cholestasis of pregnancy (ICP) affects 0.2-2% of pregnant women. While the maternal clinical course of ICP is usually benign, the fetal effects can be severe spanning from spontaneous preterm birth to fetal demise to long term effects on the health of the progeny. ICP is characterized by high maternal serum levels of bile acids and placental and hepatic bile acids accumulation. Intrahepatic cholestasis, in the non-pregnant state, has been also linked to alterations of the mitochondrial activity attributed to high oxidative stress rates driven by high intracellular bile acids concentrations. Here we explored the hypothesis that elevated bile acid levels of ICP modify the placental mitochondrial activity. METHODS: By using a set of 12 ICP and 12 control placenta samples, we assessed the expression of all 13 mitochondrial-encoded protein-coding genes and the mitochondrial DNA (mtDNA) relative abundance by real-time PCR. We also assessed the oxidative stress status by measuring DNA damage by ELISA. RESULTS: We determined that: 1) the expression of MT-ND4L (+53% - p < 0.01), MT-ND4 (-19%-0.05 < p ≤ 0.01), MT-ND5 (+40% - p < 0.01), MT-CYTB (+35% - p < 0.01) is associated with ICP; 2) the mtDNA relative abundance is not associated with ICP (0.098 in ICP vs 0.118 in controls - p > 0.05); 3) the oxidative stress status is associated with ICP (4403.9 pM 8-oxo-dG/µg DNA in ICP vs 3809.8 pM 8-oxo-dG/µg DNA in controls - p < 0.01). DISCUSSION: This preliminary study suggests that mitochondria in placenta respond to high oxidative stress to modify their gene expression which may play an important role in the pathophysiology of ICP.
