Abstract
OBJECTIVE This study aimed to evaluate fetal biometrics as predictors of shoulder dystocia (SD) in a low-risk obstetrical population. STUDY DESIGN Participants were enrolled as part of a U.S.-based prospective cohort study of fetal growth in low-risk singleton gestations (n = 2,802). Eligible women had liveborn singletons ≥2,500 g delivered vaginally. Sociodemographic, anthropometric, and pregnancy outcome data were abstracted by research staff. The diagnosis of SD was based on the recorded clinical impression of the delivering physician. Simple logistic regression models were used to examine associations between fetal biometrics and SD. Fetal biometric cut points, selected by Youden's J and clinical determination, were identified to optimize predictive capability. A final model for SD prediction was constructed using backward selection. Our dataset was randomly divided into training (60%) and test (40%) datasets for model building and internal validation. RESULTS A total of 1,691 women (98.7%) had an uncomplicated vaginal delivery, while 23 (1.3%) experienced SD. There were no differences in sociodemographic or maternal anthropometrics between groups. Epidural anesthesia use was significantly more common (100 vs. 82.4%; p = 0.03) among women who experienced SD compared with those who did not. Amniotic fluid maximal vertical pocket was also significantly greater among SD cases (5.8 ± 1.7 vs. 5.1 ± 1.5 cm; odds ratio = 1.32 [95% confidence interval: 1.03,1.69]). Several fetal biometric measures were significantly associated with SD when dichotomized based on clinically selected cut-off points. A final prediction model was internally valid with an area under the curve of 0.90 (95% confidence interval: 0.81, 0.99). At a model probability of 1%, sensitivity (71.4%), specificity (77.5%), positive (3.5%), and negative predictive values (99.6%) did not indicate the ability of the model to predict SD in a clinically meaningful way. CONCLUSION Other than epidural anesthesia use, neither sociodemographic nor maternal anthropometrics were significantly associated with SD in this low-risk population. Both individually and in combination, fetal biometrics had limited ability to predict SD and lack clinical usefulness. KEY POINTS · SD unpredictable in low-risk women.. · Fetal biometry does not reliably predict SD.. · Epidural use associated with increased SD risk.. · SD prediction models clinically inefficient..

Abstract
OBJECTIVES Decisional conflict and regret about prenatal genetic screening and diagnostic tests may have important consequences in the current pregnancy and for future reproductive decisions. Identifying mechanisms that reduce conflict associated with the decision to use or decline these options is necessary for optimal patient counseling. METHODS We conducted a cluster-randomized controlled trial of a shared decision-making tool (NEST) at the beginning of prenatal care. Enrolled patients completed follow-up surveys at the time of testing (QTT) and in the second-third trimester (QFF), including the Decision Conflict Scale (DCS). Total DCS scores were analyzed using a multivariate linear mixed-effect model. RESULTS Of the total number of participants (n=502) enrolled, 449 completed the QTT and QFF surveys. The mean age of participants was 31.6±3.8, with most parous at the time of study participation (n=321; 71.7 %). Both the NEST (the intervention) and control groups had lower median total DCS scores at QFF (NEST 13.3 [1.7, 25.0] vs. control 16.7 [1.7, 25.0]; p=0.24) compared to QTT (NEST 20.8 [5.0, 25.0] vs. control 18.3 [3.3, 26.7]; p=0.89). Participants exposed to NEST had lower decisional conflict at QFF compared to control (β -3.889; [CI -7.341, -0.437]; p=0.027). CONCLUSIONS Using a shared decision-making tool at the start of prenatal care decreased decisional conflict regarding prenatal genetic testing. Such interventions have the potential to provide an important form of decision-making support for patients facing the unique type of complex and preference-based choices about the use of prenatal genetic tests.

Abstract
BACKGROUND There are limited data to guide the diagnosis and management of vasa previa. Currently, what is known is largely based on case reports or series and cohort studies. OBJECTIVE This study aimed to systematically collect and classify expert opinions and achieve consensus on the diagnosis and clinical management of vasa previa using focus group discussions and a Delphi technique. STUDY DESIGN A 4-round focus group discussion and a 3-round Delphi survey of an international panel of experts on vasa previa were conducted. Experts were selected on the basis of their publication record on vasa previa. First, we convened a focus group discussion panel of 20 experts and agreed on which issues were unresolved in the diagnosis and management of vasa previa. A 3-round anonymous electronic survey was then sent to the full expert panel. Survey questions were presented on the diagnosis and management of vasa previa, which the experts were asked to rate on a 5-point Likert scale (from "strongly disagree"=1 to "strongly agree"=5). Consensus was defined as a median score of 5. Following responses to each round, any statements that had median scores of ≤3 were deemed to have had no consensus and were excluded. Statements with a median score of 4 were revised and re-presented to the experts in the next round. Consensus and nonconsensus statements were then aggregated. RESULTS A total of 68 international experts were invited to participate in the study, of which 57 participated. Experts were from 13 countries on 5 continents and have contributed to >80% of published cohort studies on vasa previa, as well as national and international society guidelines. Completion rates were 84%, 93%, and 91% for the first, second, and third rounds, respectively, and 71% completed all 3 rounds. The panel reached a consensus on 26 statements regarding the diagnosis and key points of management of vasa previa, including the following: (1) although there is no agreement on the distance between the fetal vessels and the cervical internal os to define vasa previa, the definition should not be limited to a 2-cm distance; (2) all pregnancies should be screened for vasa previa with routine examination for placental cord insertion and a color Doppler sweep of the region over the cervix at the second-trimester anatomy scan; (3) when a low-lying placenta or placenta previa is found in the second trimester, a transvaginal ultrasound with Doppler should be performed at approximately 32 weeks to rule out vasa previa; (4) outpatient management of asymptomatic patients without risk factors for preterm birth is reasonable; (5) asymptomatic patients with vasa previa should be delivered by scheduled cesarean delivery between 35 and 37 weeks of gestation; and (6) there was no agreement on routine hospitalization, avoidance of intercourse, or use of 3-dimensional ultrasound for diagnosis of vasa previa. CONCLUSION Through focus group discussion and a Delphi process, an international expert panel reached consensus on the definition, screening, clinical management, and timing of delivery in vasa previa, which could inform the development of new clinical guidelines.

Abstract
A series of five fetuses with a Phrygian cap gallbladder, a condition infrequently reported in the antenatal period, is reported. In all cases, examination of the fetal gallbladder displayed the characteristic folding of the fundus over the body. No associated findings were detected. The gallbladder length was longer than normal in all cases, suggesting that this anomaly could represent a deformity rather than a primary malformation. This might be caused by excessive longitudinal growth of the gallbladder, eventually folding after the fundus reaches the anterior border of the liver and is then diverted laterally by the abdominal wall.

Abstract
BACKGROUND Crown-rump length discordance, defined as ≥10% discordance, has been investigated as an early sonographic marker of subsequent growth abnormalities and is associated with an increased risk of fetal loss in twin pregnancies. Previous studies have not investigated the prevalence of fetal aneuploidy or structural anomalies in twins with discordance or the independent association of crown-rump length discordance with adverse perinatal outcomes. Moreover, data are limited on cell-free DNA screening for aneuploidy in dichorionic twins with discordance. OBJECTIVE This study aimed to evaluate whether crown-rump length discordance in dichorionic twins between 11 and 14 weeks of gestation is associated with a higher risk of aneuploidy, structural anomalies, or adverse perinatal outcomes and to assess the performance of cell-free DNA screening in dichorionic twin pregnancies with crown-rump length discordance. STUDY DESIGN This was a secondary analysis of a multicenter retrospective cohort study that evaluated the performance of cell-free DNA screening for the common trisomies in twin pregnancies from December 2011 to February 2020. For this secondary analysis, we included live dichorionic pregnancies with crown-rump length measurements between 11 and 14 weeks of gestation. First, we compared twin pregnancies with discordant crown-rump lengths with twin pregnancies with concordant crown-rump lengths and analyzed the prevalence of aneuploidy and fetal structural anomalies in either twin. Second, we compared the prevalence of a composite adverse perinatal outcome, which included preterm birth at <34 weeks of gestation, hypertensive disorders of pregnancy, stillbirth or miscarriage, small-for-gestational-age birthweight, and birthweight discordance. Moreover, we assessed the performance of cell-free DNA screening in pregnancies with and without crown-rump length discordance. Outcomes were compared with multivariable regression to adjust for confounders. RESULTS Of 987 dichorionic twins, 142 (14%) had crown-rump length discordance. The prevalence of aneuploidy was higher in twins with crown-rump length discordance than in twins with concordance (9.9% vs 3.9%, respectively; adjusted relative risk, 2.7; 95% confidence interval, 1.4-4.9). Similarly, structural anomalies (adjusted relative risk, 2.5; 95% confidence interval, 1.4-4.4]) and composite adverse perinatal outcomes (adjusted relative risk, 1.2; 95% confidence interval, 1.04-1.3) were significantly higher in twins with discordance. A stratified analysis demonstrated that even without other ultrasound markers, there were increased risks of aneuploidy (adjusted relative risk, 3.5; 95% confidence interval, 1.5-8.4) and structural anomalies (adjusted relative risk, 2.7; 95% confidence interval, 1.5-4.8) in twins with CRL discordance. Cell-free DNA screening had high negative predictive values for trisomy 21, trisomy 18, and trisomy 13, regardless of crown-rump length discordance, with 1 false-negative for trisomy 21 in a twin pregnancy with discordance. CONCLUSION Crown-rump length discordance in dichorionic twins is associated with an increased risk of aneuploidy, structural anomalies, and adverse perinatal outcomes, even without other sonographic abnormalities. Cell-free DNA screening demonstrated high sensitivity and negative predictive values irrespective of crown-rump length discordance; however, 1 false-negative result illustrated that there is a role for diagnostic testing. These data may prove useful in identifying twin pregnancies that may benefit from increased screening and surveillance and are not ascertained by other early sonographic markers.

Abstract
BACKGROUND Analysis of cell-free DNA from maternal blood provides effective screening for trisomy 21 in singleton pregnancies. Data on cell-free DNA screening in twin gestations are promising although limited. In previous twin studies, cell-free DNA screening was primarily performed in the second trimester and many studies did not report chorionicity. OBJECTIVE This study aimed to evaluate the screening performance of cell-free DNA for trisomy 21 in twin pregnancies in a large, diverse cohort. A secondary aim was to evaluate screening performance for trisomy 18 and trisomy 13. STUDY DESIGN This was a retrospective cohort study of twin pregnancies from 17 centers for which cell-free DNA screening was performed from December 2011 to February 2020 by one laboratory using massively parallel sequencing technology. Medical record review was conducted for all newborns and data on the birth outcome, the presence of any congenital abnormalities, phenotypic appearance at birth, and any chromosomal testing that was undertaken in the antenatal or postnatal period were extracted. Cases with a possible fetal chromosomal abnormality with no genetic test results were reviewed by a committee of maternal-fetal medicine geneticists. Cases with a vanishing twin and inadequate follow-up information were excluded. A minimum of 35 confirmed cases of trisomy 21 was required to capture a sensitivity of at least 90% with a prevalence of at least 1.9% with 80% power. Test characteristics were calculated for each outcome. RESULTS A total of 1764 samples were sent for twin cell-free DNA screening. Of those, 78 cases with a vanishing twin and 239 cases with inadequate follow-up were excluded, leaving a total of 1447 cases for inclusion in the analysis. The median maternal age was 35 years and the median gestational age at cell-free DNA testing was 12.3 weeks. In total, 81% of the twins were dichorionic. The median fetal fraction was 12.4%. Trisomy 21 was detected in 41 of 42 pregnancies, yielding a detection rate of 97.6% (95% confidence interval, 83.8-99.7). There was 1 false negative and no false positive cases. Trisomy 21 was detected in 38 out of 39 dichorionic twin pregnancies, yielding a detection rate of 97.4% (95% confidence interval, 82.6-99.7). Trisomy 18 was detected in 10 of the 10 affected pregnancies. There was 1 false positive case. Trisomy 13 was detected in 4 of the 5 cases, yielding a detection rate of 80% (95% confidence interval, 11.1-99.2). There was one false negative and no false positive cases. The nonreportable rate was low at 3.9 %. CONCLUSION Cell-free DNA testing is effective in screening for trisomy 21 in twin gestations from the first trimester of pregnancy. Detection of trisomy 21 was high in dichorionic and monochorionic twins, and the nonreportable result rates were low. This study included high numbers of cases of trisomy 18 and 13 when compared with the current literature. Although screening for these conditions in twins seems to be promising, the numbers were too small to make definitive conclusions regarding the screening efficacy for these conditions. It is possible that cell-free DNA testing performance may differ among laboratories and vary with screening methodologies.

Abstract
INTRODUCTION The detection of absent septi pellucidi (ASP) during obstetric ultrasound is a rare event. However, the clinical implications of this finding are significant. ASP can be associated with severe central nervous system anomalies such as holoprosencephaly, agenesis/dysgenesis of the corpus callosum, schizencephaly, severe ventriculomegaly, and open neural tube defects. In such cases, the prognosis is poor. When no such anomalies are identified, isolated ASP usually carries a good prognosis. However, some fetuses thought to have isolated ASP actually have septo-optic dysplasia (SOD), which is associated with optic nerve hypoplasia, hypothalamic-pituitary dysfunction, and developmental delay. CASE PRESENTATION A case in which fetal 3.0 Tesla magnetic resonance imaging (MRI) was considered crucial to definitively diagnose isolated ASP is presented. A review of the literature was conducted and analyzed to determine the role of MRI in the evaluation of fetuses with ASP, with special consideration on the differential diagnosis between isolated ASP and SOD. CONCLUSION Differentiating isolated ASP from SOD is imperative for adequate prenatal counseling. Unfortunately, making a prenatal diagnosis of SOD requires visualization and evaluation of the fetal optic nerves, chiasm, and pituitary gland, which is very demanding and not always possible using ultrasound. Fetal MRI has the potential of obtaining high-quality images of the fetal brain, and therefore this technique can be used for establishing the differential diagnosis in utero.

Abstract
BACKGROUND Gestational weight gain (GWG) and anthropometric trajectories may affect foetal programming and are potentially modifiable. OBJECTIVES To assess concomitant patterns of change in weight, circumferences and adiposity across gestation as an integrated prenatal exposure, and determine how they relate to neonatal body composition. METHODS Data are from a prospective cohort of singleton pregnancies (n = 2182) enrolled in United States perinatal centres, 2009-2013. Overall and by prepregnancy BMI group (overweight/obesity and healthy weight), joint latent trajectory models were fit with prenatal weight, mid-upper arm circumference (MUAC), triceps (TSF) and subscapular (SSF) skinfolds. Differences in neonatal body composition by trajectory class were assessed via weighted least squares. RESULTS Six trajectory patterns reflecting co-occurring changes in weight and MUAC, SSF and TSF across pregnancy were identified overall and by body mass index (BMI) group. Among people with a healthy weight BMI, some differences were observed for neonatal subcutaneous adipose tissue, and among individuals with overweight/obesity some differences in neonatal lean mass were found. Neonatal adiposity measures were higher among infants born to individuals with prepregnancy overweight/obesity. CONCLUSIONS Six integrated trajectory patterns of prenatal weight, subcutaneous adipose tissue and circumferences were observed that were minimally associated with neonatal body composition, suggesting a stronger influence of prepregnancy BMI.

Abstract
Visualization of the axial plane of the fetal abdomen is mandatory to obtain abdominal biometry in the assessment of fetal growth in the second and third trimesters. The main anatomic landmarks that must be identified in this view include the fetal stomach and the intrahepatic portion of the umbilical vein, which are easily identifiable as they appear anechoic on ultrasound. The gallbladder is the other prominent anechoic structure in this plane. Focused study of the morphological characteristics of, and spatial relationship among, these three anechoic spaces is a simple technique to detect anomalies involving fetal upper abdominal organs. In this review, the sonographic features of those conditions that can be detected using this technique, which was termed the Fetal Examination of the Anechoic Spaces of upper abdomen Technique (FEAST), are classified and illustrated.

Abstract
BACKGROUND The association between obesity (body mass index (BMI) ≥ 30 kg/m2) and pattern of medication use during pregnancy in the United States is not well-studied. Higher pre-pregnancy BMI may be associated with increases or decreases in medication use across pregnancy as symptoms (e.g. reflux) or comorbidities (e.g. gestational diabetes) requiring treatment that may be associated with higher BMI could also change with advancing gestation. OBJECTIVES To determine whether prenatal medication use, by the number and types of medications, varies by pre-pregnancy obesity status. METHODS In a secondary data analysis of a racially/ethnically diverse prospective cohort of pregnant women with low risk for fetal abnormalities enrolled in the first trimester of pregnancy and followed to delivery (singleton, 12 United States clinical sites), free text medication data were obtained at enrollment and up to five follow-up visits and abstracted from medical records at delivery. RESULTS In 436 women with obesity and 1750 women without obesity (pre-pregnancy BMI, 19-29.9 kg/m2), more than 70% of pregnant women (77% of women with and 73% of women without obesity) reported taking at least one medication during pregnancy, respectively (adjusted risk ratio (aRR)=1.10, 95% confidence interval (CI)=1.01, 1.20), with 81% reporting two and 69% reporting three or more. A total of 17 classes of medications were identified. Among medication classes consumed by at least 5% of all women, the only class that differed between women with and without obesity was hormones and synthetic substitutes (including steroids, progesterone, diabetes, and thyroid medications) in which women with obesity took more medications (11 vs. 5%, aRR = 1.9, 95% CI = 1.38, 2.61) compared to women without obesity. Within this class, a higher percentage of women with obesity took diabetes medications (2.3 vs. 0.7%) and progesterone (3.4 vs. 1.3%) than their non-obese counterparts. Similar percentages of women with and without obesity reported consuming medications in the remaining medication classes including central nervous system agents (50 and 46%), gastrointestinal drugs (43 and 40%), anti-infective agents (23 and 21%), antihistamines (20 and 17%), autonomic drugs (10 and 9%), and respiratory tract agents (7 and 6%), respectively (p > 0.05 for all adjusted comparisons). There were no differences in medication use by obesity status across gestation. Since the study exclusion criteria limited the non-obese group to women without thyroid disease, in a sensitivity analysis we excluded all women who reported thyroid medication intake and still a higher proportion of women with obesity took the hormones and synthetic substitutes class compared to women without obesity. CONCLUSION Our findings suggest that pre-pregnancy obesity in otherwise healthy women is associated with a higher use of only selected medications (such as diabetes medications and progesterone) during pregnancy, while the intake of other more common medication types such as analgesics, antibiotics, and antacids does not vary by pre-pregnancy obesity status. As medication safety information for prenatal consumption is insufficient for many medications, these findings highlight the need for a more in-depth examination of factors associated with prenatal medication use.

Abstract
BACKGROUND Preeclampsia is a hypertensive disease unique to pregnancy and has a significant impact on maternal and neonatal morbidity and mortality. Daily aspirin has been demonstrated to reduce the risk of preeclampsia. The American College of Obstetricians and Gynecologists recommends daily low-dose aspirin, ideally before 16 weeks' gestation, in at-risk patients for preeclampsia risk reduction. This study examined whether patients at-risk for preeclampsia by the American College of Obstetricians and Gynecologists criteria recalled aspirin recommendation and factors associated with treatment adherence. OBJECTIVE This study examined whether patients at-risk for preeclampsia by the American College of Obstetricians and Gynecologists criteria recalled aspirin recommendation and factors associated with treatment adherence. STUDY DESIGN This study used an anonymous written survey. Pregnant patients were asked to record self-reported risk factors and to recall recommendation to take aspirin for preeclampsia prophylaxis. Participants were then determined to be high-, moderate-, or low-risk on the basis of the American College of Obstetricians and Gynecologists guidelines. Self-reported adherence to recommendations and factors contributing to the patients' decisions to take or decline aspirin were assessed. Secondary outcomes included demographic characteristics of adherent patients and patients who did not recall aspirin recommendation. RESULTS A total of 544 surveys were distributed and 500 were returned (91.9% response rate). Of the 104 high-risk pregnancies identified, aspirin was recommended in 60 (57.7%; 95% confidence interval, 0.48-0.67). Of the 269 patients with 2 or more moderate-risk factors, aspirin was recommended for 13 (4.8%; 95% confidence interval, 0.03-0.08). Among the participants who recalled aspirin recommendation, adherence was similar between high-risk (81.7%) and moderate-risk (76.9%) groups (P=.69). Patients with chronic hypertension, a history of preeclampsia or gestational hypertension in a previous pregnancy, and pregestational diabetes mellitus were most likely to report receiving aspirin recommendation (78.8%, 76.5%, 63.8%, and 53.3%, respectively). No high-risk factor was associated with a decreased likelihood of adherence. Nonadherent patients rarely discussed their decision with their medical provider (5.9%). In the 42.3% of high-risk participants who did not recall aspirin recommendation, autoimmune disease, multiple gestation, and kidney disease were the most prevalent risk factors (42.9%, 35.7%, and 25.0%, respectively). CONCLUSION In the population studied, many at-risk patients, as defined by the American College of Obstetricians and Gynecologists criteria, did not recall recommendations to take aspirin for preeclampsia prophylaxis. This raises concerns for absent or ineffective counseling. Of the patients who recalled aspirin recommendation, most reported adherence, and a history of hypertensive disorders or preeclampsia, autoimmune disease, and pregestational diabetes mellitus were most often associated with adherence. There was no single factor most strongly associated with intentional nonadherence.

Abstract
OBJECTIVE This study aimed to describe the overall quantity and type of supplements and medications used during pregnancy in a low-risk cohort and to examine any racial/ethnic differences in intake. STUDY DESIGN We used data from 2,164 racially/ethnically diverse, nonobese, and low-risk pregnant women participating without pre-pregnancy chronic conditions in a prospective cohort study at 12 sites across the United States. Medication data were self-reported as free text in enrollment, follow-up visit questionnaires, and abstracted from medical records at delivery. Supplements and medications data were mapped to their active ingredients and categorized into corresponding classes using the Slone Drug Dictionary. The total number and classes of supplements and medications consumed during pregnancy were calculated. Modified Poisson regression models were used to estimate the racial/ethnic differences in supplements and medications intake. All models were adjusted for maternal sociodemographic factors and study site. RESULTS 98% of women took at least one supplement during pregnancy, with prenatal vitamins/multivitamins being most common. While only 31% reported taking no medications during pregnancy, 23% took one, 18% took two, and 28% took three or more. The percentage of women taking at least one medication during pregnancy was highest among non-Hispanic white women and lowest among Asians (84 vs. 55%, p < 0.001). All racial/ethnic groups reported taking the same top four medication classes including central nervous system agents, gastrointestinal drugs, anti-infective agents, and antihistamines. Compared with non-Hispanic white women, Hispanic (adjusted relative risk [aRR]: 0.84, 95% confidence interval [CI]: 0.71-0.98), and Asian women (aRR: 0.83, 95% CI: 0.70-0.98) were less likely to take central nervous system agents, as well as gastrointestinal drugs (Hispanics aRR: 0.79, 95% CI: 0.66-0.94; Asians aRR = 0.75, 95% CI: 0.63-0.90), and antihistamines (Hispanics aRR: 0.65, 95% CI: 0.47-0.92). CONCLUSION Supplement intake was nearly universal. Medication use was also common among this low-risk pregnancy cohort and differed by race/ethnicity. GOV IDENTIFIER NCT00912132.

Abstract
BACKGROUND Accumulating evidence indicates that maternal diets are important for optimizing maternal and offspring health. Existing research lacks comprehensive profiles of maternal diets throughout pregnancy, especially in a racially/ethnically diverse obstetrical population. OBJECTIVE The aim was to characterize diets in a longitudinal US pregnancy cohort by trimester, race/ethnicity, and prepregnancy BMI. METHODS Data were obtained from pregnant women in the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Fetal Growth Studies-Singleton cohort (2009-2013). A food-frequency questionnaire (FFQ) at 8-13 wk of gestation assessed periconception and first-trimester diet (n = 1615). Automated, self-administered, 24-h dietary recalls targeted at 16-22, 24-29, 30-33, and 34-37 wk of gestation assessed second- and third-trimester diets (n = 1817 women/6791 recalls). The Healthy Eating Index-2010 (HEI-2010) assessed diet quality (i.e., adherence to US Dietary Guidelines). Variations in weighted energy-adjusted means for foods and nutrients were examined by trimester, self-identified race/ethnicity, and self-reported prepregnancy BMI. RESULTS Mean (95% CI) HEI-2010 was 65.9 (64.9, 67.0) during periconception to the first trimester assessed with an FFQ and 51.6 (50.8, 52.4) and 51.5 (50.7, 52.3) during the second trimester and third trimester, respectively, assessed using 24-h recalls. No significant differences were observed between the second and third trimester in macronutrients, micronutrients, foods, or HEI-2010 components (P ≥ 0.05). Periconception to first-trimester HEI-2010 was highest among Asian/Pacific Islander [67.2 (65.9, 68.6)] and lowest among non-Hispanic Black [58.7 (57.5, 60.0)] women and highest among women with normal weight [67.2 (66.1, 68.4)] and lowest among women with obesity [63.5 (62.1, 64.9)]. Similar rankings were observed in the second/third trimesters. CONCLUSIONS Most pregnant women in this cohort reported dietary intakes that, on average, did not meet US Dietary Guidelines for nonpregnant individuals. Also, diet differed across race/ethnic groups and by prepregnancy BMI, with the lowest overall dietary quality in all trimesters among non-Hispanic Black women and women with obesity. No meaningful changes in dietary intake were observed between the second and third trimesters.

Abstract
PURPOSE In vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI) is generally regarded as an indication for fetal echocardiography due to a reported increased risk of congenital abnormalities including cardiac anomalies. In this study we evaluated the utility of fetal echocardiography after anatomic survey in an experienced center. METHODS This was a retrospective case review of in vitro fertilization with intracytoplasmic sperm injection pregnancies who had echocardiography in our institution from January 1996 to October 2010. RESULTS Records from 85 mothers and 110 fetuses were identified. During anatomic survey, six cardiac anomalies were identified, including four ventricular septal defects, one pulmonary-aortic disproportion, and one post-valvular pulmonary artery dilatation. At fetal echocardiography, two of the four ventricular septal defects were confirmed and an additional three were identified. The most common cardiac anomaly seen in our population of IVF-ICSI pregnancies was ventricular septal defect, which was identified in 3.6% of all cases in the neonatal period. Of ventricular septal defects identified in the prenatal period, 71% resolved before birth. CONCLUSION In experienced centers, a fetal echocardiography may not be necessary if the 3 vessels tracheal view of the heart is evaluated and the heart is evaluated carefully for a ventricular septal defect.

Abstract
BACKGROUND Fetal growth patterns in pregnancy-associated hypertensive disorders is poorly understood because prospective longitudinal data are lacking. OBJECTIVE The objective of the study was to compare longitudinal fetal growth trajectories between normotensive women and those with pregnancy-associated hypertensive disorders. STUDY DESIGN This is a study based on data from a prospective longitudinal cohort study of fetal growth performed at 12 US sites (2009-2013). Project gestational age was confirmed by ultrasound between 8 weeks 0 days and 13 weels 6 days, and up to 6 ultrasounds were performed across gestation. Hypertensive disorders were diagnosed based on 2002 American College of Obstetricians and Gynecologists guidelines and grouped hierarchically as severe preeclampsia (including eclampsia or HELLP [hemolysis, elevated liver enzymes, and low platelet count] syndrome), mild preeclampsia, severe gestational hypertension, mild gestational hypertension, or unspecified hypertension. Women without any hypertensive disorder constituted the normotensive group. Growth curves for estimated fetal weight and individual biometric parameters including biparietal diameter, head circumference, abdominal circumference, and femur and humerus length were calculated for each group using linear mixed models with cubic splines. Global and weekly pairwise comparisons were performed between women with a hypertensive disorder compared with normotensive women to analyze differences while adjusting for confounding variables. Delivery gestational age and birthweights were compared among groups. RESULTS Of 2462 women analyzed, 2296 (93.3%) were normotensive, 63 (2.6%) had mild gestational hypertension, 54 (2.2%) mild preeclampsia, 32 (1.3%) severe preeclampsia, and 17 (0.7%) unspecified hypertension. Compared with normotensive women, those with severe preeclampsia had estimated fetal weights that were reduced between 22 and 38 weeks (all weekly pairwise values of P < .008). Women with severe preeclampsia compared with those without hypertension also had significantly smaller fetal abdominal circumference between 23-31 and 33-37 weeks' gestation (weekly pairwise values of P < .04). Scattered weekly growth differences were noted on other biometric parameters between these 2 groups. The consistent differences in estimated fetal weight and abdominal circumference were not observed between women with other hypertensive disorders and those who were normotensive. Women with severe preeclampsia delivered significantly earlier (mean gestational age 35.9 ± 3.2 weeks) than the other groups (global P < .0001). Birthweights in the severe preeclampsia group were also significantly lower (mean -949.5 g [95% confidence interval, -1117.7 to -781.2 g]; P < .0001) than in the normotensive group. CONCLUSION Among women with pregnancy-associated hypertensive disorders, only those destined to develop severe preeclampsia demonstrated a significant and consistent difference in fetal growth (ie, smaller estimated fetal weight and abdominal circumference) when compared with normotensive women.

Abstract
BACKGROUND Prior studies have reported an increased risk for preterm delivery following a term cesarean delivery. However, these studies did not adjust for high-risk conditions related to the first cesarean delivery and are known to recur. OBJECTIVE The objective of the study was to determine whether there is an association between term cesarean delivery in the first pregnancy and subsequent spontaneous or indicated preterm delivery. STUDY DESIGN This was a retrospective cohort study of women with the first 2 consecutive singleton deliveries (2007-2014) identified through a linked pregnancy database at a single institution. Women with a first pregnancy that resulted in cesarean delivery at term were compared with women whose first pregnancy resulted in a vaginal delivery at term. Exclusion criteria were known to recur medical or obstetrical complications during the first pregnancy. A propensity score analysis was performed by matching women who underwent a cesarean delivery with those who underwent a vaginal delivery in the first pregnancy. The association between cesarean delivery in the first pregnancy and preterm delivery in the second pregnancy in this matched set was examined using conditional logistic regression. The primary outcome was overall preterm delivery <37 weeks in the second pregnancy. Secondary outcomes included type of preterm delivery (spontaneous vs indicated), late preterm delivery (34-36 6/7 weeks), early preterm delivery (<34 weeks), and small-for-gestational-age birth. RESULTS Of a total of 6456 linked pregnancies, 2284 deliveries were matched; 1142 were preceded by cesarean delivery and 1142 were preceded by vaginal delivery. The main indications for cesarean delivery in the first pregnancy were dystocia in 703 (61.5%), nonreassuring fetal status in 222 (19.4%), breech presentation in 100 (8.8%), and other in 84 (7.4%). The mean (SD) gestational ages at delivery for the second pregnancy was 38.8 (1.8) and 38.9 (1.7) weeks, respectively, for prior cesarean delivery and vaginal delivery. The risks of preterm delivery in the second pregnancy among women with a previous cesarean and vaginal delivery were 6.0% and 5.2%, respectively (adjusted odds ratio, 1.46, 95% confidence interval, [CI] 0.77-2.76). In an analysis stratified by the type of preterm delivery in the second pregnancy, no associations were seen between cesarean delivery in the first pregnancy and spontaneous preterm delivery (4.6% vs 3.9%; adjusted odds ratio, 1.40, 95% confidence interval, 0.59-3.32) or indicated preterm delivery (1.6% vs 1.4%; adjusted odds ratio, 1.21, 95% confidence interval, 0.60-2.46). Similarly, no significant differences were found in late preterm delivery (4.6% vs 4.1%; adjusted odds ratio, 1.13, 95% confidence interval, 0.55-2.29), early preterm delivery (1.6% vs 1.2%; adjusted odds ratio, 1.25, 95% confidence interval, 0.59-2.67), or neonates with birthweight less than the fifth percentile for gestational age (3.6% vs 2.2%; adjusted odds ratio, 1.26, 95% confidence interval, 0.52-3.06). CONCLUSION After robust adjustment for confounders through a propensity score analysis related to the indication for the first cesarean delivery at term, cesarean delivery is not associated with an increase in preterm delivery, spontaneous or indicated, in the subsequent pregnancy.

Abstract
IMPORTANCE Despite the increasing prevalence of pregravid obesity, systematic evaluation of the association of maternal obesity with fetal growth trajectories is lacking. OBJECTIVE To characterize differences in fetal growth trajectories between obese and nonobese pregnant women, and to identify the timing of any observed differences. DESIGN, SETTING, AND PARTICIPANTS The Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Growth Studies-Singletons study enrolled cohorts of pregnant women at 12 US health care institutions. Obese women (with prepregnancy body mass index > 30) and nonobese women (prepregnancy body mass indexes, 19-29.9) without major chronic diseases were recruited between 8 weeks and 0 days' gestation and 13 weeks and 6 days' gestation. A mixed longitudinal randomization scheme randomized participants into 1 of 4 schedules for 2-dimensional and 3-dimensional ultrasonograms to capture weekly fetal growth data throughout the remainder of their pregnancies. MAIN OUTCOMES AND MEASURES On each ultrasonogram, fetal humerus length, femur length, biparietal diameter, head circumference, and abdominal circumference were measured. Fetal growth curves were estimated using linear mixed models with cubic splines. Median differences in the fetal measures at each gestational week of the obese and nonobese participants were examined using the likelihood ratio and Wald tests after adjustment for maternal characteristics. RESULTS The study enrolled 468 obese and 2334 nonobese women between 8 weeks and 0 days' gestation and 13 weeks and 6 days' gestation. After a priori exclusion criteria, 443 obese and 2320 nonobese women composed the final cohort. Commencing at 21 weeks' gestation, femur length and humerus length were significantly longer for fetuses of obese woman than those of nonobese women. Differences persisted in obese and nonobese groups through 38 weeks' gestation (median femur length, 71.0 vs 70.2 mm; P = .01; median humerus length, 62.2 vs 61.6 mm; P = .03). Averaged across gestation, head circumference was significantly larger in fetuses of obese women than those of nonobese women (P = .02). Fetal abdominal circumference was not greater in the obese cohort than in the nonobese cohort but was significantly larger than in fetuses of normal-weight women (with body mass indexes between 19.0-24.9) commencing at 32 weeks (median, 282.1 vs 280.2 mm; P = .04). Starting from 30 weeks' gestation, estimated fetal weight was significantly larger for the fetuses of obese women (median, 1512 g [95% CI, 1494-1530 g] vs 1492 g [95% CI, 1484-1499 g]) and the difference grew as gestational age increased. Birth weight was higher by almost 100 g in neonates born to obese women than to nonobese women (mean, 3373.2 vs 3279.5 g). CONCLUSIONS AND RELEVANCE As early as 32 weeks' gestation, fetuses of obese women had higher weights than fetuses of nonobese women. The mechanisms and long-term health implications of these findings are not yet established.

Abstract
The anterior complex of the fetal brain is a group of structures that are important to evaluate during the routine anatomic survey to exclude several serious brain malformations. These structures include the cavum septum pellucidum, anterior horns, interhemispheric fissure, callosal sulcus, and corpus callosum. The relationship between these structures is easily remembered with the presented visual cartoon. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:477-479, 2017.

Abstract
OBJECTIVES To determine whether fetuses with an isolated aberrant course of the right subclavian artery (ARSA) have increased risk for chromosomal abnormalities, including trisomy 21 or 22q11 deletion. METHODS We performed a retrospective chart review of all fetuses with antenatally diagnosed ARSA. Data were collected from fetal anatomic surveys, fetal echocardiograms, noninvasive trisomy 21 screening programs, invasive genetic studies, and neonatal records. RESULTS Seventy-nine fetuses with ARSA were identified at 20.3 ± 3.8 weeks' gestation. Forty-eight fetuses underwent chromosomal evaluation. Of those, seven had trisomy 21. Four other fetuses had unusual karyotype abnormalities. All fetuses with genetic anomalies had additional aberrant ultrasound findings. There were three spontaneous fetal deaths (trisomy 21-2 and Wolf-Hirshhorn-1). Nine pregnancies were terminated because of abnormalities and one died as a result of hypoplastic left heart syndrome. No neonate was found or suspected to have 22q11.2 deletion. The ARSA was isolated in 43 fetuses; all had unremarkable neonatal outcomes, and none were readmitted within 6 months after discharge. CONCLUSIONS As an apparently isolated finding, ARSA is benign and not associated with trisomy 21 or 22q11.2 deletion. The finding of ARSA, however, warrants a detailed fetal ultrasound. All fetuses with ARSA and genetic anomalies had additional ultrasound findings.

Abstract
OBJECTIVE Fetal growth is associated with long-term health yet no appropriate standards exist for the early identification of undergrown or overgrown fetuses. We sought to develop contemporary fetal growth standards for 4 self-identified US racial/ethnic groups. STUDY DESIGN We recruited for prospective follow-up 2334 healthy women with low-risk, singleton pregnancies from 12 community and perinatal centers from July 2009 through January 2013. The cohort comprised: 614 (26%) non-Hispanic whites, 611 (26%) non-Hispanic blacks, 649 (28%) Hispanics, and 460 (20%) Asians. Women were screened at 8w0d to 13w6d for maternal health status associated with presumably normal fetal growth (aged 18-40 years; body mass index 19.0-29.9 kg/m(2); healthy lifestyles and living conditions; low-risk medical and obstetrical history); 92% of recruited women completed the protocol. Women were randomized among 4 ultrasonography schedules for longitudinal fetal measurement using the Voluson E8 (GE Healthcare, Milwaukee, WI). In-person interviews and anthropometric assessments were conducted at each visit; medical records were abstracted. The fetuses of 1737 (74%) women continued to be low risk (uncomplicated pregnancy, absent anomalies) at birth, and their measurements were included in the standards. Racial/ethnic-specific fetal growth curves were estimated using linear mixed models with cubic splines. Estimated fetal weight (EFW) and biometric parameter percentiles (5th, 50th, 95th) were determined for each gestational week and comparisons made by race/ethnicity, with and without adjustment for maternal and sociodemographic factors. RESULTS EFW differed significantly by race/ethnicity >20 weeks. Specifically at 39 weeks, the 5th, 50th, and 95th percentiles were 2790, 3505, and 4402 g for white; 2633, 3336, and 4226 g for Hispanic; 2621, 3270, and 4078 g for Asian; and 2622, 3260, and 4053 g for black women (adjusted global P < .001). For individual parameters, racial/ethnic differences by order of detection were: humerus and femur lengths (10 weeks), abdominal circumference (16 weeks), head circumference (21 weeks), and biparietal diameter (27 weeks). The study-derived standard based solely on the white group erroneously classifies as much as 15% of non-white fetuses as growth restricted (EFW <5th percentile). CONCLUSION Significant differences in fetal growth were found among the 4 groups. Racial/ethnic-specific standards improve the precision in evaluating fetal growth.

Abstract
BACKGROUND Cell-free DNA (cfDNA) testing for fetal trisomy is highly effective among high-risk women. However, there have been few direct, well-powered studies comparing cfDNA testing with standard screening during the first trimester in routine prenatal populations. METHODS In this prospective, multicenter, blinded study conducted at 35 international centers, we assigned pregnant women presenting for aneuploidy screening at 10 to 14 weeks of gestation to undergo both standard screening (with measurement of nuchal translucency and biochemical analytes) and cfDNA testing. Participants received the results of standard screening; the results of cfDNA testing were blinded. Determination of the birth outcome was based on diagnostic genetic testing or newborn examination. The primary outcome was the area under the receiver-operating-characteristic curve (AUC) for trisomy 21 (Down's syndrome) with cfDNA testing versus standard screening. We also evaluated cfDNA testing and standard screening to assess the risk of trisomies 18 and 13. RESULTS Of 18,955 women who were enrolled, results from 15,841 were available for analysis. The mean maternal age was 30.7 years, and the mean gestational age at testing was 12.5 weeks. The AUC for trisomy 21 was 0.999 for cfDNA testing and 0.958 for standard screening (P=0.001). Trisomy 21 was detected in 38 of 38 women (100%; 95% confidence interval [CI], 90.7 to 100) in the cfDNA-testing group, as compared with 30 of 38 women (78.9%; 95% CI, 62.7 to 90.4) in the standard-screening group (P=0.008). False positive rates were 0.06% (95% CI, 0.03 to 0.11) in the cfDNA group and 5.4% (95% CI, 5.1 to 5.8) in the standard-screening group (P<0.001). The positive predictive value for cfDNA testing was 80.9% (95% CI, 66.7 to 90.9), as compared with 3.4% (95% CI, 2.3 to 4.8) for standard screening (P<0.001). CONCLUSIONS In this large, routine prenatal-screening population, cfDNA testing for trisomy 21 had higher sensitivity, a lower false positive rate, and higher positive predictive value than did standard screening with the measurement of nuchal translucency and biochemical analytes.

Abstract
BACKGROUND Thrombotic thrombocytopenic purpura is a rare but serious medical complication, but is relatively common among patients with human immunodeficiency virus (HIV) infection. It is characterized by the pentad of thrombocytopenia, microangiopathic hemolytic anemia, neurological symptoms, fever, and renal abnormalities. However, the pentad is often incomplete, especially in HIV-positive patients. CASE An HIV-positive patient complained of easy bruising, hematuria, fever, myalgias, and headache during the second trimester of pregnancy. Laboratory testing revealed hemolytic anemia and severe thrombocytopenia. Bone marrow biopsy was consistent with thrombocytopenic purpura. The patient recovered after plasmapheresis. At 36 weeks' gestation, she was delivered for preeclampsia and fetal growth restriction. CONCLUSION Absence of the classic pentad seen in thrombocytopenic purpura among pregnant HIV-positive patients may make the diagnosis of thrombocytopenic purpura challenging. Frequent monitoring of patients with thrombotic thrombocytopenic purpura for signs and symptoms of preeclampsia and fetal growth assessment is suggested.

Abstract
OBJECTIVE Our objective was to characterize the oxidative metabolism of estradiol by human term placenta and its modulation by cigarette smoking. METHODS Placental microsomes were prepared from term placentas obtained from 13 cigarette smokers (20 to 30 cigarettes per day until the time of delivery) and 13 control subjects who were nonsmokers. Estrogen metabolism was studied by incubation of 250 nmol/L [(3)H]estradiol with placental microsomes and NADPH, and the estrogen metabolites were determined by HPLC and gas chromatography-mass spectrometry. RESULTS 2-Hydroxyestradiol was the major hydroxyestrogen detected, followed by 6alpha-hydroxyestradiol. Small amounts of several other hydroxyestrogen metabolites (4-hydroxyestradiol, 6beta-hydroxyestradiol, 7alpha-hydroxyestradiol, and 16alpha-hydroxyestradiol) were also detected. Large amounts of estrone plus small amounts of 2-hydroxyestrone and unidentified nonpolar metabolites were formed. Cigarette smoking stimulated the placental hydroxylation of benzo[a ]pyrene by about 16-fold. Cigarette smoking had little or no effect on the overall rate of placental estradiol metabolism or on the formation of estrone, 2-hydroxyestradiol, 2-hydroxyestrone, or 16alpha-hydroxyestradiol. However, placental formation of 4-hydroxyestradiol and 7alpha-hydroxyestradiol was increased 38% (P =.08) and 150% (P =.05), respectively, in cigarette smokers. The formation of 6alpha-hydroxyestradiol was decreased 33% (P =.04). Metabolic formation of 15alpha-hydroxyestradiol was observed during incubations of estradiol with placental microsomes from 11 of the 13 cigarette smokers, but this metabolite was not detected during incubations with placental microsomes from any of the 13 nonsmokers. Analysis of data from all 26 placentas showed that the 15alpha-hydroxylation of estradiol was highly correlated with benzo[a ]pyrene hydroxylation (r = 0.93; P <.001). CONCLUSIONS Many hydroxylated estradiol metabolites were formed by placental microsomes from cigarette smokers and nonsmokers. 15alpha-Hydroxylation of estradiol was markedly stimulated in the placentas of cigarette smokers.

Abstract
OBJECTIVE To compare the frequency of visualization of echogenic intracardiac foci in different cardiac views. METHODS Women having ultrasonographic examinations between October 1997 and July 1998 were prospectively evaluated if a fetal echogenic intracardiac focus was seen in either ventricle. RESULTS Echogenic intracardiac foci were seen in 89 fetuses in whom both the apical and lateral 4-chamber heart views were obtained. Eight-six fetuses (97%) had a single focus (83 in the left ventricle and 3 in the right ventricle), and 3 (3%) had 2 foci. Echogenic intracardiac foci were seen in the apical 4-chamber view in 89 (100%) and in the lateral 4-chamber view in only 26 (29%; P = .001). CONCLUSIONS Echogenic intracardiac foci are not easily seen in the lateral 4-chamber view. Studies that suggest an increased risk of aneuploidy when echogenic foci are seen should specify the orientation of the 4-chamber view used.

Abstract
OBJECTIVE To describe gestational age-dependent and -independent nomograms for fetal thyroid size. METHODS Two hundred fetuses were evaluated between 16 and 37 weeks' gestation in this cross-sectional study. RESULTS Nomograms of fetal thyroid size were created by using the 5th, 10th, 50th, 90th, and 95th percentiles based on biparietal diameter and gestational age. A second-order polynomial fit for biparietal diameter and a linear fit for gestational age best described thyroid circumference measurements. Variations in thyroid circumference measurements increased with both larger biparietal diameter and advancing gestational age. There was no intraobserver or interobserver variability in thyroid circumference measurements (P > .20). CONCLUSIONS Both biparietal diameter and gestational age serve as good predictors of fetal thyroid circumference. When the biparietal diameter is difficult to measure, gestational age can be used to assess thyroid size.

Abstract
OBJECTIVE To determine sonographic findings in Down syndrome fetuses in the third trimester. METHODS Down syndrome fetuses who had third-trimester ultrasound examinations between 25 and 41 weeks' gestation were matched for gestational age with three controls each. Fetal structural anomalies, Down syndrome dysmorphology markers (abnormal facial profile, sandal gap, tongue thrusting, clinodactyly, or hypoplastic middle phalanx of the fifth finger), and abnormal long-bone biometry (femur, humerus, tibia, and fibula; femur length to biparietal diameter ratio; and femur length to abdominal circumference ratio were abstracted from the ultrasound reports. The fetal face, hands, feet, profile, and cardiac outflow tracts are routinely evaluated in our center. RESULTS Seventeen fetuses with Down syndrome who had third-trimester ultrasound evaluations were identified. Anomalies included cardiac defects (five), tongue thrusting (three), clinodactyly (three), abnormal profile (three), sandal gap (two), and duodenal atresia (two). Of the 17 fetuses, at least one long-bone abnormality was found in 13, at least one structural or biometric anomaly was found in 15, and at least two abnormal findings existed in 11. Abnormal ultrasound findings, including structural anomalies, short bones, and Down syndrome dysmorphology markers, were more common in cases than in matched controls. CONCLUSION At least one abnormal ultrasound finding was present in 15 of 17 fetuses, and abnormal bone measurements or ratios were discovered in 13 of 17. Abnormal long-bone biometry at third-trimester ultrasound should raise the suspicion of fetal Down syndrome.

Abstract
OBJECTIVE To compare the accuracy of three different sonographic circumference measurement techniques in predicting birth weight in term fetuses, using a standard equation for estimating fetal weight. METHODS Fifty-three singleton, term fetuses were examined sonographically within 24 hours of scheduled elective cesarean delivery. The biparietal diameter (BPD) and femur length (FL) were measured using standard techniques, and head circumference (HC) and abdominal circumference (AC) were measured using three separate circumference measurement techniques (Two-diameter, ellipse, and trace). With the use of each circumference method, estimated fetal weights were determined for each fetus according to a weight-estimation formula incorporating BPD, HC, AC, and FL. The accuracy of the formula using each circumference measurement technique for predicting actual birth weight was calculated. RESULTS The mean (+/- standard deviation [SD]) gestational age was 38.1 +/- 0.9 weeks and the mean actual birth weight was 3536 +/- 472 g. The two-diameter and ellipse circumference measurements allowed more accurate birth weight prediction than did the trace method, with mean (+/- SD) percent deviations from the actual birth weight of -0.5 +/- 7.8%, 1.9 +/- 8.0%, and 8.2 +/- 11.6% (P < .05), respectively. The trace method was the least accurate, with a mean birth weight overestimation of 266 g and measurements within 10% of the actual birth weight only 49.1% of the time. The two-diameter and ellipse method yielded predicted birth weights within 10% of actual birth weights in 77.4 and 79.2% of cases, respectively. CONCLUSION Two-diameter and ellipse circumference measurement techniques are similarly accurate in predicting birth weight and both are significantly better than the trace technique.

Abstract
BACKGROUND Reported cases of uterine rupture diagnosed by ultrasound have shown fetal membranes ballooning through uterine rupture sites, or adjacent areas of hemorrhage. CASE A 27-year-old gravida 3, para 2 had open fetal surgery to repair a fetal myelomeningocele at 28 weeks' gestation. Her postoperative course was complicated by threatened preterm labor and anhydramnios. At 33 weeks' gestation, with maternal symptoms of bowel obstruction, ultrasound showed a fetal leg and section of umbilical cord protruding through the uterine wall. CONCLUSION Even in the presence of anhydramnios, uterine wall rupture was identified, because ultrasound evaluation of the uterine wall showed prolapsed fetal parts and umbilical cord. Persistent anhydramnios after open fetal surgery should prompt a search for uterine rupture.

Abstract
To date, the prenatal diagnosis of cerebellar hemorrhage has been limited to isolated case reports, which have demonstrated either a hyperechoic cerebellar hemisphere or a hyperechoic mass within the cerebellum in near-term fetuses. We demonstrate the ultrasonographic findings of intracerebellar hemorrhagic infarction in a fetus at approximately 21 weeks' gestation. In contrast to previous case reports, the hemorrhagic infarcts seen in our case were hypoechoic.

Abstract
OBJECTIVE To assess intrauterine growth in a series of nine fetuses diagnosed with Beckwith-Wiedemann syndrome. METHODS Infants confirmed postnatally to have Beckwith-Wiedemann syndrome were identified from records maintained in the Division of Clinical Genetics. Antenatal ultrasound and birth records were evaluated. Head circumference (HC), abdominal circumference (AC), and estimated fetal weight (EFW) were assigned percentiles based on gestational age. Newborn HC and birth weight were also assigned percentiles. Polyhydramnios was diagnosed using either amniotic fluid index or documented subjective assessment. RESULTS Nine infants with Beckwith-Wiedemann syndrome had antenatal ultrasound examinations. Seven of these had more than one examination. Two infants were suspected to have Beckwith-Wiedemann syndrome in utero. Important ultrasound findings included omphalocele (four), enlarged liver and kidneys (one), and enlarged liver (one). Fetal tongue protrusion on ultrasound was not identified in any fetus. Six of nine fetuses (66%) with ultrasound examinations after 25 weeks' gestation had polyhydramnios. Evaluation of the fetal HC, AC, and EFW percentiles demonstrated that fetuses with Beckwith-Wiedemann syndrome may exhibit accelerated growth as early as 25-30 weeks' gestation, but may exceed the 90th percentile only after 36 weeks' gestation. CONCLUSIONS Fetuses with omphalocele, polyhydramnios, and an AC less than the 90th percentile may have Beckwith-Wiedemann syndrome. Polyhydramnios and accelerated growth beginning between 25 and 36 weeks' gestation, even without omphalocele, should alert the physician to the possibility of Beckwith-Wiedemann syndrome.

Abstract
Bronchopulmonary sequestration is a congenital abnormality of nonfunctional pulmonary tissue that lacks normal connections with the bronchial tree. The sequestered tissue typically receives the majority of its blood supply from systemic vessels, most often the distal thoracic or upper abdominal aorta. These lesions often are associated with fetal hydrops, polyhydramnios, and persistent masses postnatally. Bronchopulmonary sequestrations are thought to require resection owing to their predisposition for chronic pulmonary infections later in life. However, spontaneous in utero resolution of these lesions can occur. This report describes the real time, color Doppler, and duplex Doppler ultrasonographic investigation of an intrathoracic bronchopulmonary sequestration that resolved spontaneously. Our investigation of this case provides new insight into a possible mechanism for spontaneous regression of bronchopulmonary sequestration.

Abstract
We report the prenatal diagnosis of mid shaft hypospadias and describe the sonographic features of fetal hypospadias including an abnormal urethral canal, ventral curvature of the distal penis, extension of the penile glans beyond the prepuce, and fetal micturation in a plane perpendicular to the penile shaft. An accurate family history is an essential part of the evaluation of the milder degrees of fetal hypospadias.

Abstract
Puerperal psychosis occurs after delivery in 1-2/1,000 births. It usually presents after delivery, however, it also may present in the antepartum period. We report the third case which presented prior to delivery without a preceding history of maternal puerperal psychosis and the first which presented with catatonia and symptoms of eclampsia. Although uncommon, the first presentation of psychosis during pregnancy should be considered part of the differential diagnosis in pregnant patients presenting with altered mental status after organic causes are excluded.

Abstract
OBJECTIVE Management of a retained intrauterine contraceptive device with no visible string during early pregnancy presents a dilemma. Because these devices are frequently used by multiparous women, it is not unusual that many women with retained devices are also of advanced maternal age. We describe our experience with ultrasonographically guided first-trimester retrieval of an intrauterine contraceptive device in conjunction with chorionic villus sampling. STUDY DESIGN Patients with a first-trimester pregnancy and a retained intrauterine contraceptive device where no string was visible were offered ultrasonographically guided retrieval of the device. If the patient had genetic risks and desired prenatal diagnosis, chorionic villus sampling was offered at the same office visit. RESULTS Six patients underwent intrauterine contraceptive device retrieval, under continuous ultrasonographic guidance, by use of an intrauterine contraceptive device hook. All patients had a posterior or fundal device. One patient had two in situ: a Lippes Loop (Ortho Pharmaceutical Corp., Raritan, N.J.) removed by its string and a Cu-7 (G.D. Searle & Co., Chicago) removed under ultrasonographic guidance. The remaining five patients had a Cu-7. Four of six patients had chorionic villus sampling performed immediately after the intrauterine contraceptive device removal and one patient had chorionic villus sampling 3 weeks later. There were two losses in our series: one after a lengthy procedure and one before documented viability. All infants were structurally normal and born at term. CONCLUSION First-trimester ultrasonographically guided retrieval of a retained intrauterine contraceptive device may be safely performed in conjunction with chorionic villus sampling.

Abstract
Unlike the situation with many antimicrobial agents, there is limited experience with the use of amphotericin B during pregnancy. Although reports of fungal infections during pregnancy have been published, few describe fungemia with either Candida or Torulopsis species. We present a case of fungemia due to Torulopsis glabrata that occurred during pregnancy and that was treated with amphotericin B. Drug concentrations were measured in placental tissue, cord serum, and infant serum at delivery. Although the last dose of amphotericin B was administered 4 weeks before delivery, the concentrations in all three specimens were still within the MIC ranges for most strains of Candida albicans and T. glabrata as measured by broth dilution. We speculate that persistent tissue concentrations of amphotericin B most likely contributed to the sustained hypokalemia in the mother and the increased creatinine level in the infant. In the latter case, placental tissue may have served as the reservoir from which amphotericin B was slowly released into fetal circulation.

Abstract
Classical acquired resistance to erythromycin in Staphylococcus aureus ("MLS," or macrolide-lincosamide-streptogramin, resistance) was shown by Weisblum and colleagues to be a direct consequence of the conversion of one or more adenosine residues of 23S rRNA, within the subsequence(s) GA3G, to N6-dimethyladenosine (m62A). The methylation reaction is effected by a class of methylase, whose genes are typically plasmid- or transposon-associated, and whose synthesis is inducible by erythromycin. Using a recently obtained clinical MLS isolate of S. aureus, we have further defined the methylation locus as YGG X m62A X AAGAC; and have shown that this subsequence occurs once in the 23S RNA and that it is essentially completely methylated in all copies of 23S RNA that accumulate in induced cultures. Similar findings were obtained with laboratory S. aureus strains containing two well-characterized evolutionary variants (ermB, ermC) of MLS methylase genes. Analyses of a strain of E. coli containing the ermC gene indicated that the specificity of the methylase gene was unchanged, but that its expression was muted. Even after prolonged periods of induction, the strain manifested only partial resistance to erythromycin, and only about one-third of the copies of the MLS subsequence were methylated in such "induced" cultures. Since the E. coli 23S RNA sequence is known in its entirety, localization of the MLS subsequence is in this case unambiguous; as inferred by homology arguments applied earlier to the S. aureus data, the subsequence is in a highly conserved region of 23S RNA considered to contribute to the peptidyl transferase center of the ribosome.

Abstract
We have determined the sequence of an oligonucleotide from the large ribosomal subunit RNA of Staphylococcus aureus whose methylation renders the organism resistant to erythromycin and other antibiotics (the "MLS" phenotype). Analysis of RNase A digests of [3H]methyl-, 32P-labeled RNA yielded the sequence GG . m6(2)A . AAGACp, where m6(2)A is an N6-dimethylated adenosine residue that in sensitive cells is unmethylated. Comparison with homologous sequences recently reported for Saccharomyces cerevesiae mitochondria indicates that an A to G mutation in this latter system mimics dimethylation in St. aureus with regard to functional consequences.
