Abstract
OBJECTIVE The random urine protein-to-creatinine ratio (UPCR) is a screening test used for predicting clinically significant proteinuria (urine protein ≥ 300 mg) during pregnancy. No consensus exists on the optimal random UPCR cutoff for performing follow-up 24 hour urine (24H) total protein collection. We aim to evaluate the test performance of random UPCR in predicting proteinuria in a contemporary cohort. STUDY DESIGN This was a retrospective cohort study of pregnant patients at our institution from 2014 to 2018 with a random UPCR and follow-up 24H protein collection. The primary analysis estimated the test characteristics (sensitivity, specificity, positive and negative predictive values) of using random UPCR for the detection of proteinuria defined as urine protein ≥300 mg on 24H protein collection. UPCR cutoffs from 0.10 to 0.30 mg/dL were evaluated, receiver operator characteristic (ROC) curve was constructed, and area under the curve (AUC) was determined. A secondary analysis examined the correlation between UPCR and 24H protein using least squares regression and Pearson correlation. RESULTS Paired UPCR and 24H collection results were available for 1,120 patients. Mean gestational age at time of UPCR was 31.1 ± 5.1 weeks and 687 (61.3%) of patients had a 24H ≥300 mg. UPCR <0.10 mg/dL effectively excluded proteinuria ≥300 mg on 24H collection, while UPCR ≥0.18 mg/dL correctly classifies proteinuria with 91% sensitivity, 57% specificity, 77% positive predictive value, and 79% negative predictive value. UPCR ≥1.07 mg/dL had 100% specificity for 24 hour proteinuria. The area under ROC curve was 0.86. UPCR and 24H collection were highly correlated with a Pearson correlation coefficient of 0.85. After our institution lowered the threshold to obtain a 24H from UPCR ≥0.20 mg/dL to ≥0.10 mg/dL in May 2017, the percentage of patients meeting criteria for 24H collection increased from 57.8 to 84.4%. CONCLUSION The AUC and Pearson correlation suggest random UPCR is a high performance test for the prediction of proteinuria on 24H. Optimal test performance is dependent upon clinical consideration and upon the implications of the disease or condition. A random UPCR screen positive threshold of 0.18 mg/dL maximizes sensitivity to identify clinically significant proteinuria. KEY POINTS · Random urine protein to creatinine ratio is a high performance test for proteinuria.. · A random UPCR threshold of 0.18 mg/dL maximizes sensitivity to identify proteinuria.. · Optimal test performance is dependent on the disease or clinical condition..

Abstract
OBJECTIVE To evaluate the association between continuous glucose monitoring in pregnant people with type 2 diabetes and perinatal outcomes. METHODS This was a retrospective cohort study of pregnant people with type 2 diabetes who received prenatal care and delivered singleton, nonanomalous neonates at a single academic tertiary care center from November 1, 2019, to February 28, 2023. The primary outcome was a composite of neonatal morbidity, including hypoglycemia, hyperbilirubinemia, shoulder dystocia, large for gestational age at birth, preterm birth, neonatal intensive care unit (NICU) admission, or perinatal death. Demographics and outcomes were compared by type of monitoring (continuous glucose monitoring vs intermittent self-monitoring of blood glucose), and multivariable logistic regression estimated the association between continuous glucose monitoring use and perinatal outcomes. RESULTS Of 360 pregnant people who met the inclusion criteria, 82 (22.7%) used continuous glucose monitoring. The mean gestational age at continuous glucose monitoring initiation was 21.3±6.4 weeks. The use of continuous glucose monitoring was associated with lower odds of the primary composite neonatal morbidity (65.9% continuous glucose monitoring vs 77.0% self-monitoring of blood glucose, adjusted odds ratio [aOR] 0.48, 95% CI, 0.24-0.94). Continuous glucose monitoring use was also associated with lower odds of preterm birth (13.4% vs 25.2%, aOR 0.48, 95% CI, 0.25-0.93) and NICU admission (33.8% vs 47.6%, aOR 0.36, 95% CI, 0.16-0.81). CONCLUSION In pregnant people with type 2 diabetes, continuous glucose monitoring use was associated with less neonatal morbidity, fewer preterm births, and fewer NICU admissions.

Abstract
OBJECTIVES The objective of this study is to evaluate whether there is an association between in-utero exposure to nicotine and subsequent hearing dysfunction. MATERIALS AND METHODS Secondary analysis of a multicenter randomized trial to prevent congenital cytomegalovirus (CMV) infection among gravidas with primary CMV infection was conducted. Monthly intravenous immunoglobulin hyperimmune globulin therapy did not influence the rate of congenital CMV. Dyads with missing urine, fetal or neonatal demise, infants diagnosed with a major congenital anomaly, congenital CMV infection, or with evidence of middle ear dysfunction were excluded. The primary outcome was neonatal hearing impairment in one or more ears defined as abnormal distortion product otoacoustic emissions (DPOAEs; 1 to 8 kHz) that were measured within 42 days of birth. DPOAEs were interpreted using optimized frequency-specific level criteria. Cotinine was measured via enzyme-linked immunosorbent assay kits in maternal urine collected at enrollment and in the third trimester (mean gestational age 16.0 and 36.7 weeks, respectively). Blinded personnel ran samples in duplicates. Maternal urine cotinine >5 ng/mL at either time point was defined as in-utero exposure to nicotine. Multivariable logistic regression included variables associated with the primary outcome and with the exposure (p < 0.05) in univariate analysis. RESULTS Of 399 enrolled patients in the original trial, 150 were included in this analysis, of whom 46 (31%) were exposed to nicotine. The primary outcome occurred in 18 (12%) newborns and was higher in nicotine-exposed infants compared with those nonexposed (15.2 vs. 10.6%, odds ratio [OR] 1.52, 95% confidence interval [CI] 0.55-4.20), but the difference was not significantly different (adjusted odds ratio [aOR] = 1.0, 95% CI 0.30-3.31). This association was similar when exposure was stratified as heavy (>100 ng/mL, aOR 0.72, 95% CI 0.15-3.51) or mild (5-100 ng/mL, aOR 1.28, 95% CI 0.33-4.95). There was no association between nicotine exposure and frequency-specific DPOAE amplitude. CONCLUSION In a cohort of parturients with primary CMV infection, nicotine exposure was not associated with offspring hearing dysfunction assessed with DPOAEs. KEY POINTS · Nicotine exposure was quantified from maternal urine.. · Nicotine exposure was identified in 30% of the cohort.. · Exposure was not associated with offspring hearing dysfunction..

Abstract
OBJECTIVE The aim of the study is to evaluate the association between the amount of proteinuria at the time of diagnosis of preeclampsia with severe features (severe preeclampsia [SPE]) and duration of expectant management (EM) and other perinatal outcomes. STUDY DESIGN This is a retrospective cohort study of patients with SPE delivering live, non-anomalous singletons at 230/7 to 342/7 weeks' estimated gestational age (EGA) at a single tertiary center 2016 to 2018. Patients with proteinuria assessment (24-hour total urine protein or urine protein-to-creatinine ratio extrapolation) within 3 days of SPE diagnosis were included. Patients delivered for an indication other than SPE were excluded. Patients were categorized by amount of proteinuria (mg): none (≤300), mild (301-1,000), moderate (1,001-3,000), and massive (≥3,001). The primary outcome was the proportion of potential EM time achieved (%EM), i.e., days of EM divided by days from SPE diagnosis to 34 weeks. Secondary outcomes included delivery EGA, days of EM, and perinatal outcomes. Bivariable and multivariable analyses compared outcomes across groups. RESULTS Of 295 patients included, 21% had no proteinuria, 33% mild, 19% moderate, and 27% massive. Groups differed by EGA at diagnosis, age, parity, chronic hypertension, and renal disease. %EM was not significantly different between groups (adjusted β coefficient 4.1 [95% CI -5.3, 13.5] for mild proteinuria vs. none, -4.1 [95% CI -14.9, 6.6] for moderate proteinuria vs. none, and -5.6 [95% CI -16.0, 4.7] for massive proteinuria vs. none). Increasing proteinuria was associated with earlier delivery EGA but only days of EM in the mild versus no proteinuria groups. There was no significant association between proteinuria and maternal composite morbidity, but patients with mild and massive proteinuria had higher odds of neonatal composite morbidities compared with no proteinuria. CONCLUSION Among patients with SPE, proteinuria level was not consistently associated with duration of EM. However, patients with the greatest amounts of proteinuria may have worse neonatal and selected maternal outcomes. KEY POINTS · Amount of proteinuria was not associated with the duration of expectant management.. · Greater proteinuria was associated with earlier delivery in severe preeclampsia.. · Massive proteinuria in preeclampsia was associated with select adverse maternal and neonatal outcomes..

Abstract
OBJECTIVE To characterize breastfeeding behaviors and identify factors associated with breastfeeding initiation among people with hepatitis C virus (HCV) infection. METHODS We conducted a secondary analysis of a multicenter observational cohort of pregnant people with singleton gestations and HCV seropositivity. This analysis includes individuals with data on breastfeeding initiation and excludes those with human immunodeficiency virus (HIV) co-infection. The primary outcome was self-reported initiation of breastfeeding or provision of expressed breast milk. Secondary outcomes included duration of breastfeeding. Demographic and obstetric characteristics were compared between those who initiated breastfeeding and those who did not to identify associated factors. Univariable and multivariable analyses were performed. RESULTS Overall, 579 individuals (75.0% of participants in the parent study) were included. Of those, 362 (62.5%) initiated breastfeeding or provided breast milk to their infants, with a median duration of breastfeeding of 1.4 months (interquartile range 0.5-6.0). People with HCV viremia , defined as a detectable viral load at any point during pregnancy, were less likely to initiate breastfeeding than those who had an undetectable viral load (59.4 vs 71.9%, adjusted odds ratio [aOR] 0.61, 95% CI, 0.41-0.92). People with private insurance were more likely to initiate breastfeeding compared with those with public insurance or no insurance (80.0 vs 60.1%; aOR 2.43, 95% CI, 1.31-4.50). CONCLUSION Although HCV seropositivity is not a contraindication to breastfeeding regardless of viral load, rates of breastfeeding initiation were lower among people with HCV viremia than among those with an undetectable viral load.

Abstract
OBJECTIVE Our objective was to evaluate whether iodine status in pregnant patients with either subclinical hypothyroidism or hypothyroxinemia in the first half of pregnancy is associated with measures of behavior and neurodevelopment in children through the age of 5 years. STUDY DESIGN This is a secondary analysis of a multicenter study consisting of two randomized, double-masked, placebo-controlled treatment trials conducted in parallel. Patients with a singleton gestation before 20 weeks' gestation underwent thyroid screening using serum thyrotropin and free thyroxine. Participants with subclinical hypothyroidism or hypothyroxinemia were randomized to levothyroxine replacement or an identical placebo. At randomization, maternal urine was collected and stored for subsequent urinary iodine excretion analysis. Urinary iodine concentrations greater than 150 μg/L were considered iodine sufficient, and concentrations of 150 μg/L or less were considered iodine insufficient. The primary outcome was a full-scale intelligence quotient (IQ) score at the age of 5 years, the general conceptual ability score from the Differential Ability Scales-II at the age of 3 if IQ was not available, or death before 3 years. RESULTS A total of 677 pregnant participants with subclinical hypothyroidism and 526 with hypothyroxinemia were randomized. The primary outcome was available in 1,133 (94%) of children. Overall, 684 (60%) of mothers were found to have urinary iodine concentrations >150 μg/L. Children of iodine-sufficient participants with subclinical hypothyroidism had similar primary outcome scores when compared to children of iodine-insufficient participants (95 [84-105] vs. 96 [87-109], P adj = 0.73). After adjustment, there was also no difference in IQ scores among children of participants with hypothyroxinemia at 5 to 7 years of age (94 [85 - 102] and 91 [81 - 100], Padj 1/4 0.11). Treatment with levothyroxine was not associated with neurodevelopmental or behavioral outcomes regardless of maternal iodine status (p > 0.05). CONCLUSION Maternal urinary iodine concentrations ≤150 μg/L were not associated with abnormal cognitive or behavioral outcomes in offspring of participants with either subclinical hypothyroidism or hypothyroxinemia. KEY POINTS · Most pregnant patients with subclinical thyroid disease are iodine sufficient.. · Mild maternal iodine insufficiency is not associated with lower offspring IQ at 5 years.. · Iodine supplementation in subclinical thyroid disease is unlikely to improve IQ..

Abstract
OBJECTIVE The aim of the study is to evaluate whether values and the shape of the glucose curve during the oral glucose tolerance test (OGTT) in pregnancy identify women at risk of developing hypertension (HTN) later in life. STUDY DESIGN This category includes the secondary analysis of a follow-up from a mild gestational diabetes mellitus (GDM) study that included a treatment trial for mild GDM (n = 458) and an observational cohort of participants with abnormal 1-hour glucose loading test only (normal OGTT, n = 430). Participants were assessed at a median of 7 (IQR 6-8) years after their index pregnancy, and trained staff measured their blood pressure (systolic blood pressure [SBP]; diastolic blood pressure [DBP]). The association between values and the shape of the glucose curve during OGTT in the index pregnancy and the primary outcome defined as elevated BP (SBP ≥120, DBP ≥80 mm Hg, or receiving anti-HTN medications), and secondary outcome defined as stage 1 or higher (SBP ≥130, DBP ≥80 mm Hg, or receiving anti-HTN medications) at follow-up were evaluated using multivariable regression, adjusting for maternal age, body mass index, and pregnancy-associated hypertension during the index pregnancy. RESULTS There was no association between fasting, 1-hour OGTT, and the outcomes. However, the 2-hour OGTT value was positively associated (adjusted odds ratio [aRR] per 10-unit increase 1.04, 95% CI 1.01-1.08), and the 3-hour was inversely associated (aRR per 10-unit increase 0.96, 95% CI 0.93-0.99) with the primary outcome. When the shape of the OGTT curve was evaluated, a monophasic OGTT response (peak at 1 hour followed by a decline in glucose) was associated with increased risk of elevated BP (41.3vs. 23.5%, aRR 1.66, 95% CI 1.17-2.35) and stage 1 HTN or higher (28.5 vs. 14.7%, aRR 1.83, 95% CI 1.15-2.92), compared with a biphasic OGTT response. CONCLUSION Among persons with mild GDM or lesser degrees of glucose intolerance, the shape of the OGTT curve during pregnancy may help identify women who are at risk of HTN later in life, with biphasic shape to be associated with lower risk. KEY POINTS · The shape of the Oral Glucose Tolerance Test curve may help identify patients who are at risk of having elevated BP or HTN 5 to 10 years following pregnancy.. · The 2-hour Oral Glucose Tolerance Test values is positively associated with elevated BP 5 to 10 years following pregnancy.. · This supports the concept of pregnancy as a window to future health and represents a potential novel biomarker for maternal cardiovascular health screening..

Abstract
OBJECTIVE To evaluate the association between maternal blood pressure (BP) below 130/80 mm Hg compared with 130-139/80-89 mm Hg and pregnancy outcomes. METHODS We conducted a planned secondary analysis of CHAP (Chronic Hypertension and Pregnancy), an open label, multicenter, randomized controlled trial. Participants with mean BP below 140/90 mm Hg were grouped as below 130/80 mm Hg compared with 130-139/80-89 mm Hg by averaging postrandomization clinic BP throughout pregnancy. The primary composite outcome was preeclampsia with severe features, indicated preterm birth before 35 weeks of gestation, placental abruption, or fetal or neonatal death. The secondary outcome was small for gestational age (SGA). RESULTS Of 2,408 patients in CHAP, 2,096 met study criteria; 1,328 had mean BP 130-139/80-89 mm Hg and 768 had mean BP below 130/80 mm Hg. Participants with mean BP below 130/80 mm Hg were more likely to be older, on antihypertensive medication, in the active treatment arm, and to have lower BP at enrollment. Mean clinic BP below 130/80 mm Hg was associated with lower frequency of the primary outcome (16.0% vs 35.8%, adjusted relative risk 0.45; 95% CI 0.38-0.54) as well as lower risk of severe preeclampsia and indicated birth before 35 weeks of gestation. There was no association with SGA. CONCLUSION In pregnant patients with mild chronic hypertension, mean BP below 130/80 mm Hg was associated with improved pregnancy outcomes without increased risk of SGA.

Abstract
OBJECTIVE The threshold of viability, as well as cutoffs for delivery interventions and neonatal resuscitation, vary by hospital and involve complex counseling. With improvements in neonatal resuscitation and intensive care, the threshold of viability has been decreasing. Decisions regarding delivery planning and neonatal resuscitation efforts should be based on the best available evidence. Our objective was to characterize survival rates and neonatal outcomes following periviable birth at different milestones beginning with prenatal admission through 1 year of life in a contemporary cohort. STUDY DESIGN We performed a retrospective cohort study of all inborn infants without major congenital anomalies who delivered at the University of Alabama at Birmingham from 2013 to 2019 at gestational ages 22+0/7 to 25+6/7. Our primary outcome was to compared survival milestones throughout the pre- and postdelivery periods and neonatal complications in surviving newborns through 1 year of life at each gestational age. RESULTS The survival rate to 1 year of life was 49% (48-56%, 95% confidence interval [CI]) for the entire cohort and varied according to gestational age at delivery (22 weeks 15% [10-23%, 95% CI], 23 weeks 48% [43-58%, 95% CI], 24 weeks 57% [52-67%, 95% CI], 25 weeks 71% [67-82%, 95% CI]). Overall for the entire cohort, the rate of lung disease requiring respiratory support at discharge was 51%, intraventricular hemorrhage was 42%, retinopathy of prematurity was 74%, pulmonary hypertension was 30%, and concerns for cerebral palsy at 1 year of life was 25%. All outcomes improved with advancing gestational age at delivery. Of infants who delivered during the 22nd week of gestation, 50% received antenatal corticosteroids. Infants exposed to antenatal corticosteroids had more interventions, less pulmonary hypertension, and improved survival to 1 year of life. CONCLUSION Knowledge of maternal complications, longitudinal survival rates, and neonatal outcomes of periviable deliveries according to gestational age throughout the admission enhances obstetric and perinatal counseling after hospital admission. KEY POINTS · Periviable birth outcomes at different delivery milestones is important for counseling.. · Providing contemporary outcomes for periviable deliveries is critical for accurate counseling.. · Administration of antenatal corticosteroids at 22 weeks' gestation appears beneficial overall..

Abstract
OBJECTIVE To evaluate the efficacy of occipital nerve block compared with standard care , defined as acetaminophen with caffeine, for treatment of acute headache in pregnancy. METHODS We conducted a single-center, unblinded, parallel, randomized controlled trial of pregnant patients with headache and pain score higher than 3 on the visual rating scale. Patients with secondary headache, preeclampsia, or allergy or contraindication to study medications were excluded. Participants were randomized to occipital nerve block or standard care (oral 650 mg acetaminophen and 200 mg caffeine). Crossover treatment was given at 2 hours and second-line treatment at 4 hours to those with worsening visual rating scale score or visual rating scale score higher than 3. The primary outcome was headache improvement to a visual rating scale score of 3 or lower within 2 hours of initial therapy. Secondary outcomes included serial visual rating scale scores, receipt of crossover or second-line therapy, patient satisfaction, and perinatal outcomes. Outcomes were assessed in an intention-to-treat analysis. We estimated that a sample of 62 would provide 80% power to detect a difference from 85% to 50% between groups. RESULTS From February 2020 to May 2022, 62 participants were randomized to occipital nerve block (n=31) or standard care (n=31). Groups were similar except payer status. The primary outcome, headache improvement to visual rating scale score of 3 or lower, was not significantly different between groups (64.5% vs 51.6%, P =.30). The occipital nerve block group experienced lower median [interquartile range] visual rating scale scores at 1 hour (2 [0-5] vs 6 [2-7], P =.014), and more patients in the occipital nerve block group had visual rating scale scores of 3 or lower at 1 hour. Among patients receiving crossover treatment at 2 hours, the standard care group had a significantly lower visual rating scale score 1 hour after crossover to occipital nerve block than the occipital nerve block group receiving crossover to standard care ( P =.028). There were no significant differences in second-line treatment, refractory headache, satisfaction, or complications. Patients receiving occipital nerve block delivered earlier (36.6 weeks vs 37.8 weeks), but preterm birth did not differ between groups. CONCLUSION Occipital nerve block is an effective and quick-acting treatment option for acute headache in pregnancy. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov , NCT03951649.

Abstract
OBJECTIVE To estimate the rate of perinatal transmission of hepatitis C virus (HCV) infection, to identify risk factors for perinatal transmission of HCV infection, and to determine the viremic threshold for perinatal transmission. METHODS This was a prospective, multicenter, observational study of pregnant individuals at less than 24 weeks of gestation screened for HCV infection from 2012 to 2018 in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network. Individuals found to be HCV antibody-positive were followed throughout pregnancy. Children were followed for evidence of perinatal transmission at 2-6 months (HCV RNA testing) and at 18-24 months (HCV RNA and antibody testing) of life. The primary outcome was perinatal transmission, defined as positive test results at either follow-up time point. RESULTS A total of 109,379 individuals were screened for HCV infection. Of the 1,224 participants who screened positive, 772 (63.1%) enrolled and 432 of those 772 (56.0%) had data available to assess primary outcome. The overall rate of perinatal transmission was 6.0% (26/432, 95% CI 4.0-8.7%). All children with HCV infection were born to individuals with demonstrable viremia. In viremic participants (n=314), the perinatal transmission rate was 8.0% (95% CI 5.2-11.5%). Risk factors for perinatal transmission included HCV RNA greater than 106 international units/mL (adjusted odds ratio [aOR] 8.22, 95% CI 3.16-21.4) and vaginal bleeding reported at any time before delivery (aOR 3.26, 95% CI 1.32-8.03). A viremic threshold for perinatal transmission could not be established. CONCLUSION Perinatal transmission of HCV infection was limited to viremic individuals. High viral loads and antepartum bleeding were associated with perinatal transmission.

Abstract
OBJECTIVE To evaluate the association between maternal and delivery characteristics and self-reported perceived control during childbirth. METHODS A secondary analysis of a multicenter randomized trial was conducted to compare labor induction at 39 weeks of gestation with expectant management in low-risk nulliparous people. Six to 96 hours after delivery, participants who experienced labor completed the Labor Agentry Scale, a validated self-administered questionnaire to ascertain perceived control during childbirth. Scores range from 29 to 203, with higher scores indicating a sense of greater control. Multivariable linear regression was used to determine which maternal and delivery characteristics were associated with the Labor Agentry Scale score. Eligible characteristics included age, self-reported race and ethnicity, marital status, employment status, type of insurance, previous pregnancy loss before 20 weeks of gestation, body mass index (BMI), smoking, alcohol use, mode of delivery, labor pain (0-10 points), and a composite of perinatal death or severe neonatal complications. Significant variables ( P <.05) were retained in the final multivariable model, and adjusted mean differences (95% CIs) between groups were estimated. RESULTS Of 6,106 people enrolled in the trial, 6,038 experienced labor, of whom 5,750 (95.2%) completed the Labor Agentry Scale and were included in this analysis. Mean [95% CI] adjusted Labor Agentry Scale scores were significantly lower among those who identified as Asian (-6.4 [-10.5 to -2.3]) or Hispanic (-3.7 [-5.7 to -1.7]) compared with White, smoked compared with did not smoke (-2.8 [-5.5 to -0.1]), had BMIs of 35 or higher compared with less than 30 (-2.0 [-3.8 to -0.2]), were unemployed (-3.15 [-4.76 to -1.55]), did not have private health insurance (-2.61 [-4.47 to -0.76]), underwent operative vaginal (-5.1 [-7.7 to -2.6]) or cesarean (-14.4 [-16.1 to -12.6]) delivery compared with spontaneous vaginal delivery, and reported greater labor pain score of 8 or higher compared with less than 8 (-11.9 [-13.4 to -10.4]). Mean [95% CI] adjusted Labor Agentry Scale scores were significantly higher among people who were employed compared with unemployed (3.2 [1.6-4.8]) and had private compared with nonprivate insurance (2.6 [0.76-4.5]). CONCLUSION In nulliparous people at low risk, unemployment, lack of private health insurance, Asian race, Hispanic ethnicity, smoking, operative delivery, and more labor pain were associated with lower perceived control during labor.

Abstract
OBJECTIVE This study aimed to measure the association between hypertensive disorders of pregnancy (HDP) and long-term maternal metabolic and cardiovascular biomarkers. STUDY DESIGN Follow-up study of patients who completed glucose tolerance testing 5 to 10 years after enrollment in a mild gestational diabetes mellitus (GDM) treatment trial or concurrent non-GDM cohort. Maternal serum insulin concentrations and cardiovascular markers VCAM-1, VEGF, CD40L, GDF-15, and ST-2 were measured, and insulinogenic index (IGI, pancreatic β-cell function) and 1/ homeostatic model assessment (insulin resistance) were calculated. Biomarkers were compared by presence of HDP (gestational hypertension or preeclampsia) during pregnancy. Multivariable linear regression estimated the association of HDP with biomarkers, adjusting for GDM, baseline body mass index (BMI), and years since pregnancy. RESULTS Of 642 patients, 66 (10%) had HDP: 42 with gestational hypertension and 24 with preeclampsia. Patients with HDP had higher baseline and follow-up BMI, higher baseline blood pressure, and more chronic hypertension at follow-up. HDP was not associated with metabolic or cardiovascular biomarkers at follow-up. However, when HDP type was evaluated, patients with preeclampsia had lower GDF-15 levels (oxidative stress/cardiac ischemia), compared with patients without HDP (adjusted mean difference: -0.24, 95% confidence interval: -0.44, -0.03). There were no differences between gestational hypertension and no HDP. CONCLUSION In this cohort, metabolic and cardiovascular biomarkers 5 to 10 years after pregnancies did not differ by HDP. Patients with preeclampsia may have less oxidative stress/cardiac ischemia postpartum; however, this may have been observed due to chance alone given multiple comparisons. Longitudinal studies are needed to define the impact of HDP during pregnancy and interventions postpartum. KEY POINTS · Hypertensive disorders of pregnancy were not associated with metabolic dysfunction.. · Cardiovascular dysfunction was not consistently seen after pregnancy hypertension.. · Longitudinal studies with postpartum interventions after preeclampsia are needed..

Abstract
OBJECTIVE To describe cesarean delivery rates and indications at a single center in order to assess the impact of the guidelines published by the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine on trends in labor management. STUDY DESIGN Retrospective cohort study of patients ≥23 weeks' gestation delivering at a single tertiary care referral center from 2013-2018. Demographic characteristics, mode of delivery, and main indication for cesarean delivery were ascertained by individual chart review. Cesarean delivery indications (mutually exclusive) were: repeat cesarean delivery, non-reassuring fetal status, malpresentation, maternal indications (e.g., placenta previa or genital herpes simplex virus), failed labor (any stage labor arrest), or other (i.e., fetal anomaly, elective). Polynomial (cubic) regression models were used to model rates of cesarean delivery and indications over time. Subgroup analyses further examined trends in nulliparous women. RESULTS Of the 24,637 patients delivered during the study period, 24,050 were included in the analysis; 7,835 (32.6%) had a cesarean delivery. The rates of overall cesarean delivery were significantly different over time (p<0.001), declining to a minimum of 30.9% in 2014 and peaking at 34.6% in 2018. With regards to the overall cesarean delivery indications, there were no significant differences over time. When limited to nulliparous patients, the rates of cesarean delivery were also noted to be significantly different over time (p=0.02) nadiring at 30% in 2015 from 35.4% in 2013 and then rising up to 33.9% in 2018. As for nulliparous patients, there was no significant difference in primary cesarean delivery indications over time except for non-reassuring fetal status (p=0.049). CONCLUSIONS Despite changes in labor management definitions and guidelines encouraging vaginal birth, the rates of overall cesarean delivery did not decrease over time. The indications for delivery, particularly failed labor, repeat cesarean delivery, and malpresentation have not significantly changed over time.

Abstract
OBJECTIVE This study aimed to estimate the association between number of maternal comorbidities and duration of expectant management and perinatal outcomes in patients with preeclampsia with severe features. STUDY DESIGN Retrospective cohort of patients with preeclampsia with severe features delivering live, nonanomalous singletons at 23 to 342/7 weeks' gestation at a single center from 2016 to 2018. Patients delivered for an indication other than severe preeclampsia were excluded. Patients were categorized based on the number (0, 1, or ≥2) of comorbidities present: chronic hypertension, pregestational diabetes, chronic kidney disease, and systemic lupus erythematosus. The primary outcome was proportion of potential expectant management time achieved, that is, days of expectant management achieved divided by total potential expectant management time (days from severe preeclampsia diagnosis to 340/7 weeks). Secondary outcomes included delivery gestational age, days of expectant management, and perinatal outcomes. Outcomes were compared in bivariable and multivariable analyses. RESULTS Of 337 patients included, 167 (50%) had 0, 151 (45%) had 1, and 19 (5%) had ≥2 comorbidities. Groups differed with respect to age, body mass index, race/ethnicity, insurance, and parity. The median proportion of potential expectant management achieved in this cohort was 1.8% (interquartile range: 0-15.4), and did not differ by number of comorbidities (adjusted β: 5.3 [95% confidence interval [CI]: -2.1 to 12.9] for 1 comorbidity vs. 0 and adjusted β: -2.9 [95% CI: -18.0 to 12.2] for ≥2 comorbidities vs. 0). There was no difference in delivery gestational age or duration of expectant management in days. Patients with ≥2 (vs. 0) comorbidities had higher odds of composite maternal morbidity (adjusted odds ratio: 3.0 [95% CI: 1.1-8.2]). There was no association between number of comorbidities and composite neonatal morbidity. CONCLUSION Among patients with preeclampsia with severe features, the number of comorbidities was not associated with duration of expectant management; however, patients with ≥2 comorbidities had higher odds of adverse maternal outcomes. KEY POINTS · Greater number of medical comorbidities were not associated with expectant management duration.. · Two or more medical comorbidities were associated with higher odds of adverse maternal outcomes.. · Expectant management should be undertaken cautiously in medically complicated patients..

Abstract
OBJECTIVE Lymphangioleiomyomatosis (LAM) is a rare, multisystem disease that primarily affects women of reproductive age. Disease progression has been linked to estrogen exposure, and as such many patients are advised to avoid pregnancy. Data are limited regarding the interaction between LAM and pregnancy, and as such we performed a systematic review to summarize available literature reporting outcomes of pregnancies complicated by maternal LAM. STUDY DESIGN This was a systematic review including randomized controlled trials, observational studies, systematic reviews, case reports, clinical practice guidelines, and quality improvement studies with full-text manuscripts or abstracts in the English language with primary data on pregnant or postpartum patients with LAM. The primary outcome was maternal outcomes during pregnancy as well as pregnancy outcomes. Secondary outcomes were neonatal outcomes and long-term maternal outcomes. This search occurred in July 2020 and included MEDLINE, Scopus, clinicaltrials.gov, Embase, and Cochrane Central. Risk of bias was ascertained using the Newcastle-Ottawa Scale. Our systematic review was registered with PROSPERO as protocol number CRD 42020191402. RESULTS A total of 175 publications were identified in our initial search; ultimately 31 studies were included. Six (19%) studies were retrospective cohort studies and 25 (81%) studies were case reports. Patients diagnosed during pregnancy had worse pregnancy outcomes compared to those diagnosed with LAM prior to pregnancy. Multiple studies reported a significant risk of pneumothoraces during pregnancy. Other significant risks included preterm delivery, chylothoraces, and pulmonary function deterioration. A proposed strategy for preconception counseling and antenatal management is provided. CONCLUSION Patients diagnosed with LAM during pregnancy generally experience worse outcomes including recurrent pneumothoraces and preterm delivery as compared to patients with a LAM diagnosis prior to pregnancy. Given that there are limited studies available, and that the majority are low-quality evidence and subject to bias, further investigation of the interaction between LAM and pregnancy is warranted to guide patient care and counseling. KEY POINTS · Data are limited on the effects of lymphangioleiomyomatosis on pregnancy outcomes.. · We performed a systematic review to summarize pregnancy outcomes complicated by LAM.. · Patients diagnosed with LAM during pregnancy experience worse outcomes..

Abstract
OBJECTIVE The aim of this study was to evaluate the association of mild gestational diabetes mellitus (GDM) and obesity with metabolic and cardiovascular markers 5 to 10 years after pregnancy. STUDY DESIGN This was a secondary analysis of 5- to 10-year follow-up study of a mild GDM treatment trial and concurrent observational cohort of participants ineligible for the trial with abnormal 1-hour glucose challenge test only. Participants with 2-hour glucose tolerance test at follow-up were included. The primary exposures were mild GDM and obesity. The outcomes were insulinogenic index (IGI), 1/homeostatic model assessment of insulin resistance (HOMA-IR), and cardiovascular markers vascular endothelial growth factor, (VEGF), vascular cell adhesion molecule 1 (VCAM-1), cluster of differentiation 40 ligand (CD40L), growth differentiation factor 15 (GDF-15), and suppression of tumorgenesis 2 (ST-2). Multivariable linear regression estimated the association of GDM and obesity with biomarkers. RESULTS Of 951 participants in the parent study, 642 (68%) were included. Lower 1/HOMA-IR were observed in treated and untreated GDM groups, compared with non-GDM (mean differences, -0.24 and -0.15; 95% confidence intervals [CIs], -0.36 to -0.12 and -0.28 to -0.03, respectively). Lower VCAM-1 (angiogenesis) was observed in treated GDM group (mean difference, -0.11; 95% CI, -0.19 to -0.03). GDM was not associated with IGI or other biomarkers. Obesity was associated with lower 1/HOMA-IR (mean difference, -0.42; 95% CI, -0.52 to -0.32), but not other biomarkers. CONCLUSION Prior GDM and obesity are associated with more insulin resistance but not insulin secretion or consistent cardiovascular dysfunction 5 to 10 years after delivery. KEY POINTS · Mild GDM increases the risk of insulin resistance 5 to 10 years postpartum but not pancreatic dysfunction.. · Obesity increases the risk of insulin resistance 5 to 10 years postpartum but not pancreatic dysfunction.. · Neither mild GDM nor obesity increased the risk of cardiovascular dysfunction 5 to 10 years postpartum..

Abstract
OBJECTIVE In the antenatal late preterm steroids (ALPS) trial betamethasone significantly decreased short-term neonatal respiratory morbidity but increased the risk of neonatal hypoglycemia, diagnosed only categorically (<40 mg/dL). We sought to better characterize the nature, duration, and treatment for hypoglycemia. STUDY DESIGN Secondary analysis of infants from ALPS, a multicenter trial randomizing women at risk for late preterm delivery to betamethasone or placebo. This study was a reabstraction of all available charts from the parent trial, all of which were requested. Unreviewed charts included those lost to follow-up or from sites not participating in the reabstraction. Duration of hypoglycemia (<40 mg/dL), lowest value and treatment, if any, were assessed by group. Measures of association and regression models were used where appropriate. RESULTS Of 2,831 randomized, 2,609 (92.2%) were included. There were 387 (29.3%) and 223 (17.3%) with hypoglycemia in the betamethasone and placebo groups, respectively (relative risk [RR]: 1.69, 95% confidence interval [CI]: 1.46-1.96). Hypoglycemia generally occurred in the first 24 hours in both groups: 374/385 (97.1%) in the betamethasone group and 214/222 (96.4%) in the placebo group (p = 0.63). Of 387 neonates with hypoglycemia in the betamethasone group, 132 (34.1%) received treatment, while 73/223 (32.7%) received treatment in placebo group (p = 0.73). The lowest recorded blood sugar was similar between groups. Most hypoglycemia resolved by 24 hours in both (93.0 vs. 89.3% in the betamethasone and placebo groups, respectively, p = 0.18). Among infants with hypoglycemia in the first 24 hours, the time to resolution was shorter in the betamethasone group (2.80 [interquartile range: 2.03-7.03) vs. 3.74 (interquartile range: 2.15-15.08) hours; p = 0.002]. Persistence for >72 hours was rare and similar in both groups, nine (2.4%, betamethasone) and four (1.9%, placebo, p = 0.18). CONCLUSION In this cohort, hypoglycemia was transient and most received no treatment, with a quicker resolution in the betamethasone group. Prolonged hypoglycemia was uncommon irrespective of steroid exposure. KEY POINTS · Hypoglycemia was transient and approximately two-thirds received no treatment.. · Neonates in the ALPS trial who received betamethasone had a shorter time to resolution than those with hypoglycemia in the placebo group.. · Prolonged hypoglycemia occurred in approximately 2 out of 100 late preterm newborns, irrespective of antenatal steroid exposure..

Abstract
OBJECTIVE The aim of this study was to evaluate whether being small for gestational age (SGA) or large for gestational age (LGA) or having a small or large head circumference (HC) at birth is associated with adverse neurodevelopmental outcomes. STUDY DESIGN This is a secondary analysis of a multicenter negative randomized trial of thyroxine therapy for subclinical hypothyroid disorders in pregnancy. The primary outcome was child intelligence quotient (IQ) at 5 years of age. Secondary outcomes included several neurodevelopmental measures. Associations between the outcomes in children with SGA (<10th percentile) or LGA (>90th percentile) birth weights, using ethnicity- and sex-specific population nomogram as well as nomograms from the National Fetal Growth (NFG) study, were compared with the referent of those with appropriate for gestational age (AGA) birth weight. Similar analyses were performed for HC. RESULTS Using the population nomogram, 90 (8.2%) were SGA and 112 (10.2%) were LGA. SGA neonates were more likely to be born preterm to mothers who were younger, smoked, and were less likely to have less than a high school education, whereas LGA neonates were more likely to be born to mothers who were older and have higher body mass index, compared with AGA neonates. SGA at birth was associated with a decrease in the child IQ at 5 years of age by 3.34 (95% confidence interval [CI], 0.54-6.14) points, and an increase in odds of child with an IQ < 85 (adjusted odds ratio [aOR], 1.9; 95% CI, 1.1-3.2). There was no association between SGA and other secondary outcomes, or between LGA and the primary or secondary outcomes. Using the NFG standards, SGA at birth remained associated with a decrease in the child IQ at 5 years of age by 3.14 (95% CI, 0.22-6.05) points and higher odds of an IQ < 85 (aOR, 2.3; 95% CI, 1.3-4.1), but none of the other secondary outcomes. HC was not associated with the primary outcome, and there were no consistent associations of these standards with the secondary outcomes. CONCLUSION In this cohort of pregnant individuals with hypothyroid disorders, SGA birth weight was associated with a decrease in child IQ and greater odds of child IQ < 85 at 5 years of age. Using a fetal growth standard did not appear to improve the detection of newborns at risk of adverse neurodevelopment.

Abstract
OBJECTIVE In the OFFSITE II randomized controlled trial, outpatient cervical ripening with a Foley catheter (CF) in nulliparous patients undergoing elective induction of labor (eIOL) shortened the time from admission to delivery. Given that patients with obesity have protracted labor and higher rates of failed IOL, we sought to determine if outpatient ripening with a CF may be even more beneficial for this high-risk group. STUDY DESIGN We performed a secondary analysis of the OFFSITE II randomized controlled trial. For this analysis, all patients from the primary trial were classified by their intervention assignment (inpatient vs. outpatient) and also by their admission body mass index (BMI) class (BMI ≥ 30 and BMI < 30 kg/m2). The primary outcome was time from labor and delivery (L&D) admission to delivery. Secondary outcomes included cesarean delivery, time from admission to hospital discharge, and rates of clinically diagnosed chorioamnionitis and endometritis. RESULTS In patients with BMI ≥ 30, the primary outcome, time from admission to delivery, (18.0 [13.5-20.9] vs. 20.4 [16.6-31.3] hours, p = 0.01), as well as total hospitalization length (3.2 [2.5-3.3] vs. 3.4 [3.1-4.3] days, p = 0.02) were shorter in the outpatient group. There were no differences in rates of chorioamnionitis or endometritis in outpatient compared with inpatient CF. Furthermore, in those with a BMI ≥ 30, the cesarean rate was significantly lower with outpatient CF (19.4% vs. 44.7%, p = 0.03); it was not statistically different in patients with BMI < 30. CONCLUSION In this exploratory retrospective secondary analysis of the OFFSITE II randomized control trial, we found that in patients with BMI ≥ 30 undergoing eIOL, outpatient CF was associated with a lower time from L&D admission until delivery. This was also associated with a shorter time of total hospital duration and decreased the rate of cesarean, a benefit not detected in the overall analysis presented in the primary study. In nulliparas undergoing induction of labor, ripening with outpatient cervical Foley may even more significantly reduce labor duration, total hospital duration, and the rate of cesarean in patients with obesity. KEY POINTS · Outpatient CF was associated with a lower time from L&D admission until delivery in obese nulliparas.. · Outpatient CF was associated with a shorter time of total hospital duration in obese nulliparas.. · Outpatient CF was associated with a decreased rate of cesarean birth in obese nulliparas..

Venous thromboembolism and adverse outcomes in highest thromboembolism risk patients compared with those at lower risk. Am J Obstet Gynecol MFM 2022; 4:100720. [PMID: 35977704 DOI: 10.1016/j.ajogmf.2022.100720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 08/08/2022] [Accepted: 08/11/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND A risk-based institutional protocol for inpatient heparin-based venous thromboembolism prophylaxis in a general obstetrical population previously demonstrated a greater than 2-fold increase in wound hematomas with no change in the frequency of thromboembolism. OBJECTIVE We sought to compare the rates of thromboembolism and bleeding outcomes in patients at the highest risk for thromboembolism (eg, those with a history of thromboembolism or thrombophilia who require anticoagulation prophylaxis or therapy throughout pregnancy) than low-risk patients. STUDY DESIGN We performed a retrospective cohort study of all deliveries >20 weeks at a single center from 2013-2018. Patients were categorized as high-risk (received outpatient heparin-based prophylaxis or treatment) or low-risk (no outpatient anticoagulation). The primary outcome was newly diagnosed postpartum thromboembolism; the main secondary outcome was wound/perineal hematoma. The outcomes were compared between the high- and low-risk cohorts. Adjusted odds ratios (with 95% confidence intervals) were calculated with the low-risk group as reference. RESULTS Of 24,303 total deliveries, 395 (1.7%) were high-risk and 23,905 (98.3%) were low-risk. Among the low-risk patients, 8.6% received anticoagulation prophylaxis in accordance with our risk-based inpatient thromboembolism prophylaxis protocol. High-risk patients were more likely to be older and have a higher body mass index, earlier delivery gestational age, medical comorbidities, and pregnancy complications, eg, preeclampsia. Despite outpatient antepartum anticoagulation, high-risk patients had an 11-fold increased risk of thromboembolism (adjusted odds ratio, 11.1 [4.7-26.2]) than low-risk patients. High-risk patients also had significantly more wound/perineal hematomas (adjusted odds ratio, 4.8 [2.7-8.4]), overall wound complications (adjusted odds ratio, 3.0 [2.0-4.4]), blood transfusions, intensive care unit admissions, maternal deaths, and longer maternal lengths of stay. CONCLUSION Patients at the highest risk of obstetrical thromboembolism had an 11-fold increased risk of thromboembolism with a more moderate increase (∼5-fold) in postpartum wound and bleeding complications than low-risk patients. This more favorable risk or benefit profile supports current anticoagulation recommendations in high-risk patients.

BJOG 2022; 129:1396-1403. [PMID: 34927787 PMCID: PMC9207156 DOI: 10.1111/1471-0528.17059] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 11/15/2021] [Accepted: 11/24/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To evaluate whether hypertensive disorders of pregnancy (HDP) among low-risk nulliparous women expectantly managed at or after 39 weeks of gestation are associated with adverse outcomes. DESIGN Secondary analysis of a randomised trial. SETTING Multicentre, USA. POPULATION Individuals in the expectantly managed group who delivered on or after 39 weeks. METHODS Multivariable analysis to estimate adjusted relative risks (aRR) for binomial outcomes, adjusted odds ratios (aOR) for multinomial outcomes and 95% CI. MAIN OUTCOME MEASURES Composite adverse maternal outcome including placental abruption, pulmonary oedema, postpartum haemorrhage, postpartum infection, venous thromboembolism or intensive care unit admission. Secondary outcomes included a composite of perinatal death or severe neonatal complications, mode of delivery, small and large for gestational age and neonatal intermediate or intensive unit length of stay. RESULTS Of the 3044 women randomised to expectant management in the original trial, 2718 (89.3%) were eligible for this analysis, of whom 373 (13.7%) developed HDP. Compared with participants who remained normotensive, those who developed HDP were more likely to experience the maternal composite (12% versus 6%, aRR 1.84, 95% CI 1.33-2.54) and caesarean delivery (29% versus 23%, aOR 1.32, 95% CI 1.01-1.71). Differences between the two groups were not significantly different for the adverse perinatal composite (7% versus 5%, aRR 1.38, 95% CI 0.92-2.07) or for other secondary outcomes. CONCLUSION Almost 14% of low-risk nulliparous individuals expectantly managed at 39 weeks developed HDP, and were more likely to experience adverse maternal outcomes compared with those who did not develop HDP. TWEETABLE ABSTRACT Almost 14% of low-risk nulliparous individuals expectantly managed at 39 weeks developed hypertensive disorders of pregnancy, and were more likely to experience adverse maternal outcomes compared with those who did not develop hypertensive disorders.

Abstract
OBJECTIVE The long-term impact of hypertensive disorders of pregnancy (HDP) exposure on offspring health is an emerging research area. The objective of this study was to evaluate the association between a maternal diagnosis of HDP (gestational hypertension and preeclampsia) and adverse neurodevelopmental outcomes in the offspring. STUDY DESIGN This was a secondary analysis of two parallel multicenter clinical trials of thyroxine therapy for subclinical hypothyroid disorders in pregnancy. Women with singleton nonanomalous gestations diagnosed with subclinical hypothyroidism or hypothyroxinemia were randomized to thyroxine therapy or placebo. The primary outcome was child intelligence quotient (IQ) at 5 years of age. Secondary outcomes included several neurodevelopmental measures, including the Bayley-III cognitive, motor, and language scores at 12 and 24 months, Differential Ability Scales-II (DAS-II) scores at 36 months, the Conners' rating scales-revised at 48 months, and scores from the Child Behavior Checklist at 36 and 60 months. Thyroxine therapy did not influence neurodevelopment in either of the primary studies. Associations between neurodevelopment outcomes and maternal HDP were examined using univariable and multivariable analyses. RESULTS A total of 112 woman-child dyads with HDP were compared with 1,067 woman-child dyads without HDP. In univariable analysis, mean maternal age (26.7 ± 5.9 vs. 27.8 ± 5.7 years, p = 0.032) and the frequency of nulliparity (45.5 vs. 31.0%, p = 0.002) differed significantly between the two groups. Maternal socioeconomic characteristics did not differ between the groups. After adjusting for potential confounders, there were no significant differences in any primary or secondary neurodevelopment outcome between offspring exposed to HDP and those unexposed. However, when dichotomized as low or high scores, we found higher rates of language delay (language scores <85: -1 standard deviation) at 2 years of age among offspring exposed to HDP compared with those unexposed (46.5 vs. 30.5%, adjusted odds ratio = 2.22, 95% confidence interval [CI]: 1.44-3.42). CONCLUSION In this cohort of pregnant women, HDP diagnosis was associated with language delay at 2 years of age. However, other long-term neurodevelopmental outcomes in offspring were not associated with HDP. KEY POINTS · No differences were found in neurodevelopment between offspring exposed to HDP and controls.. · Higher rates of language delay at 2 years of age were found in offspring exposed to HDP.. · The results did not differ when analysis was stratified by preterm birth..

Euglycemia after antenatal late preterm steroids: a multicenter, randomized controlled trial. Am J Obstet Gynecol MFM 2022; 4:100625. [PMID: 35346889 DOI: 10.1016/j.ajogmf.2022.100625] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 03/23/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Late preterm steroid administration can induce transient maternal and thus fetal hyperglycemia, which can increase production of fetal insulin and C-peptide. Infants delivered in this setting are subsequently at increased risk for hypoglycemia. Although maternal glycemic control before delivery is a key component of care for parturients with diabetes, this intervention has not been studied in the setting of late preterm steroid administration. OBJECTIVE This study aimed to determine the effect of maternal screening for and treatment of hyperglycemia after late preterm steroid administration on fetal C-peptide levels and other metabolic markers. STUDY DESIGN This was a multicenter, randomized trial (NCT03076775) of nondiabetic parturients with a singleton gestation receiving betamethasone at 34 0/7 weeks to 36 5/7 weeks for anticipated preterm birth. Participants randomized to maternal glycemic control received fasting and 1-hour postprandial or serial intrapartum capillary blood glucose screening with insulin treatment as indicated. Those randomized to expectant management did not receive any glucose screening or treatment. The primary outcome was fetal C-peptide level measured from umbilical cord blood at delivery. Secondary outcomes included other fetal metabolic markers and neonatal hypoglycemia (glucose level <40 mg/dL). Baseline characteristics and outcomes were compared between the groups. We estimated that we would need a sample size of 144 to provide >90% power to show a 1 ng/mL decrease in C-peptide concentration (±1.5 ng/mL) at ⍺=0.05 using a 2-sample t test and 1 interim analysis. After the interim analysis, the trial was stopped for futility. RESULTS Of 491 screened parturients, 163 (33%) were deemed eligible and 86 (53%) were randomized to 1 of the treatment groups (June 2017 to February 2021). One person was lost to follow-up because of delivery at another hospital. Baseline characteristics were similar between groups. The median interval from betamethasone administration to delivery was 24 hours (interquartile range, 13-96 hours) and did not differ between groups (P=.82). Most (82%) randomized to maternal glycemic control had hyperglycemia: 80% had at least 1 fasting glucose level >95 mg/dL, 75% had at least one 1-hour postprandial glucose level >140 mg/dL, and 80% had at least 1 intrapartum glucose level >110 mg/dL. In addition, 15% had at least 1 glucose level >180 mg/dL. None had maternal hypoglycemia after insulin treatment. Compared with expectant management, maternal glycemic control did not affect the median fetal C-peptide level (1.02; interquartile range, 0.52-1.85 vs 1.09; interquartile range, 0.61-1.65; P=.97) or other metabolic markers. Maternal glycemic control also did not affect neonatal hypoglycemia (49% vs 51%; P=.83) or other secondary neonatal or maternal outcomes. There was no evidence of effect modification by gestational age or body mass index at randomization, indication for betamethasone, duration from betamethasone to delivery, maternal race or ethnicity, or neonatal sex. In addition, the results were unchanged in a sensitivity analysis using a per-protocol approach. CONCLUSION Maternal hyperglycemia was observed in most nondiabetic parturients after receiving late preterm betamethasone. However, there was no improvement in fetal metabolic status, neonatal hypoglycemia, or other neonatal or maternal outcomes with maternal glycemic control. Therefore, maternal glucose surveillance and treatment does not seem to be beneficial in nondiabetic parturients receiving late preterm steroids.

Postpartum glucose intolerance following early gestational diabetes mellitus. Am J Obstet Gynecol MFM 2022; 4:100609. [PMID: 35272093 PMCID: PMC9195159 DOI: 10.1016/j.ajogmf.2022.100609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Revised: 02/25/2022] [Accepted: 02/28/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND Patients with gestational diabetes mellitus are at increased risk for type 2 diabetes mellitus or glucose intolerance postpartum compared with those without diabetes mellitus. OBJECTIVE We aimed to evaluate the association between early gestational diabetes mellitus and postpartum dysglycemia compared with gestational diabetes mellitus diagnosed by routine screening in a cohort of patients with obesity. STUDY DESIGN This was a secondary analysis of a randomized controlled trial of patients with obesity and singleton, nonanomalous gestations that compared early gestational diabetes mellitus screening at 14 to 20 weeks of gestation with routine screening at 24 to 28 weeks of gestation. Patients were included in this analysis if they were diagnosed with gestational diabetes mellitus at the primary study site. The primary outcome was postpartum dysglycemia, defined as any abnormality on 2-hour oral glucose tolerance test 6 weeks postpartum or clinical diagnosis based on hyperglycemia requiring pharmacotherapy after delivery with deferred glucose tolerance test. Maternal characteristics and outcomes were compared in bivariable analysis, and logistic regression estimated the association between early gestational diabetes mellitus and postpartum dysglycemia. RESULTS Of 119 patients included in this analysis, 30 were diagnosed by screening at <20 weeks of gestation and 89 at 24 to 28 weeks of gestation. Patients were overall similar in baseline characteristics. Patients with early gestational diabetes mellitus were more likely to have postpartum dysglycemia than those with gestational diabetes mellitus diagnosed with routine screening (36.7% vs 14.6%; odds ratio, 3.38; 95% confidence interval, 1.31-8.73). Most patients with early gestational diabetes mellitus who had postpartum dysglycemia were diagnosed clinically (n=7/11), whereas none of the patients with gestational diabetes mellitus established by routine testing were diagnosed with postpartum dysglycemia clinically. All (100%) patients with early gestational diabetes mellitus who completed a postpartum glucose tolerance test had dysglycemia compared with only 45% of patients with gestational diabetes mellitus diagnosed on routine screening. The proportion of patients who followed up for postpartum visits and the timing of follow-up were similar between groups. Postpartum glucose tolerance test completion was low but also similar between groups. CONCLUSION Although postpartum glucose tolerance test completion is low, patients with gestational diabetes mellitus before 20 weeks of gestation, seem to be at higher risk for postpartum dysglycemia than those with gestational diabetes mellitus diagnosed at routine screening in a cohort of patients with obesity. Larger studies are needed to confirm these findings, but postpartum follow-up and diabetes mellitus testing may be even more important to improve long-term health in patients with early gestational diabetes mellitus.

Quantifying the additional maternal morbidity in women with preeclampsia with severe features in whom immediate delivery is recommended. Am J Obstet Gynecol MFM 2022; 4:100565. [PMID: 35033750 DOI: 10.1016/j.ajogmf.2022.100565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 12/21/2021] [Accepted: 01/09/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND Preeclampsia with severe features when diagnosed at less than 34 weeks is associated with maternal morbidity and is managed by immediate delivery or inpatient expectant management. OBJECTIVE This study aimed to compare maternal morbidity in women with preeclampsia with severe features in whom the American College of Obstetricians and Gynecologists recommends immediate delivery versus those eligible for expectant management. STUDY DESIGN This was a retrospective cohort study of women with preeclampsia with severe features delivered between 23 to 34 weeks of gestation from 2013 to 2017 at a single tertiary center. Women were categorized into 2 groups: (1) those recommended by the American College of Obstetricians and Gynecologists for immediate delivery, that is, ineligible for expectant management, and (2) those eligible for expectant management. The primary outcome was composite postpartum maternal morbidity, which included maternal intensive care unit admission, stroke, death, and other severe morbidities. The secondary outcomes included select adverse perinatal outcomes. Groups were compared and adjusted odds ratios (95% confidence intervals) calculated. RESULTS Of the 1172 women with preeclampsia identified during the study period, 543 with preeclampsia with severe features were included for analysis: 211 (39%) were ineligible for expectant management and 332 (61%) were eligible for expectant management. Baseline characteristics, including age, body mass index, race and ethnicity, parity, marital status, and gestational age at preeclampsia diagnosis, were similar between the 2 groups. Women ineligible for expectant management had significantly higher composite postpartum maternal morbidity (adjusted odds ratio, 5.02 [95% confidence interval, 1.35-18.69]). In addition, those ineligible for expectant management were more likely to have postpartum intensive care unit admission (adjusted odds ratio, 4.19 [95% confidence interval, 1.09-16.16]) and postpartum hemoglobin level of <7 g/dL (adjusted odds ratio, 5.07 [95% confidence interval, 1.35-19.08]). There was no demonstrable difference in neonatal outcomes between the 2 groups. CONCLUSION Women with preeclampsia with severe features who were ineligible for expectant management per the American College of Obstetricians and Gynecologists guidelines had a 5-fold increased risk of maternal morbidity, confirming the need for escalation of care and delivery without delay.

Abstract
OBJECTIVE Antenatal and early neonatal nutritional environment may influence later metabolic health. Infants of mothers with gestational diabetes mellitus (GDM) have higher risk for childhood obesity and metabolic syndrome (MetS). Leptin and adiponectin are known biomarkers for MetS and may guide interventions to reduce later obesity. We sought to examine the relationship between birthweight, early infancy feeding practices, and biomarkers for MetS in offspring of women with mild GDM. STUDY DESIGN Secondary analysis of a prospective observational follow-up study on the offspring of women who participated in a multicenter randomized treatment trial on mild GDM. Children were evaluated by research coordinators and biospecimens collected at the age of 5 to 10. Plasma concentrations of leptin and adiponectin were compared between large for gestational age (LGA) and average birthweight (AGA) infants, and according to whether solid foods were introduced early (<6 months of age) or at the recommended age (≥6 months of age). Multivariable analysis adjusted for fetal sex, race/ethnicity, and maternal body mass index. RESULTS Leptin and adiponectin were measured in 336 plasma samples. In bivariate analysis, compared with AGA children, LGA children had lower leptin (5.0 ng/mL [3.6-6.0] vs. 5.8 ng/mL [4.5 = 6.6], p = 0.01) and similar adiponectin (6.3 µg/mL [5.1-7.9] vs. 6.4 µg/mL [5.3-8.6], p = 0.49) concentrations. Maternal/child characteristics were similar between the early/delayed solid feeding groups. Leptin and adiponectin concentrations were similar in the early fed and delayed feeding groups (5.8 ng/mL [4.6-6.7] vs. 5.6 ng/mL [4.2-6.6], p = 0.50 and 6.4 µg/mL [5.4-8.1] vs. 6.4 µg/mL [5.1-8.8], p = 0.85, respectively). After controlling for covariates, children who were LGA and AGA at birth had similar leptin concentrations. CONCLUSION Birthweight and early infancy feeding practice are not associated with alterations in leptin and adiponectin in children of women with mild GDM. KEY POINTS · Adipocytokines are markers of metabolic status.. · Children of women with mild GDM may be at risk for MetS.. · Biomarkers similar in LGA and AGA groups.. · Biomarkers similar in early and delayed solid-fed groups.. · Nonhuman milk does not modify effect of feeding practice..

Abstract
OBJECTIVE This study aimed to compare attendance of nutritional counseling, dietary composition, exercise patterns, and socioeconomic factors among obese women with inappropriate gestational weight gain (iGWG) versus appropriate GWG (aGWG). STUDY DESIGN Medicaid-eligible women receiving prenatal care at a tertiary care center from January 2013 to December 2015 were offered individualized nutritional counseling by a registered dietitian encouraging well-balanced meals and 150 min/wk of exercise. We conducted a prospective case-control study of obese women (body mass index or BMI ≥30) with a singleton gestation with iGWG (<11 or >20 pounds) versus aGWG (11-20 pounds). Dietary intake, activity level, and socioeconomic factors were compared with Chi-square, Fisher's exact, Student's t-test, and Wilcoxon Rank Sum tests as indicated, and odds ratios with 95% confidence intervals were calculated. Multivariate regression analysis for significant variables was performed. A subgroup analysis of women with BMI ≥40 was planned. RESULTS A total of 401 women were analyzed: 78% (n = 313) with iGWG and 22% (n = 88) with aGWG. Demographics were similar between groups. Women with iGWG less frequently reported physician reinforcement of counseling and reported more physical inactivity and unemployment; there were no differences in caloric intake or macronutrient profile between groups. Multivariate regression identified physician reinforcement and employment as independent predictors of aGWG. Among women with BMI ≥40 (n = 133), those with iGWG (78%) were less likely to attend counseling, report physician reinforcement of counseling, and have adequate caloric and protein intake when compared with those with aGWG (22%). Activity level and socioeconomic factors were not different between groups. CONCLUSION Physician reinforcement of nutritional counseling, greater activity level, and employment are associated with aGWG in women with BMI ≥30, while individualized professional nutritional counseling and dietary modifications were further associated with aGWG in women with BMI ≥40. Thus, greater focus should be placed on enhancing exposure to counseling and altering nutritional and exercise choices to optimize aGWG. KEY POINTS · Physician reinforcement of nutritional counseling by a dietitian is crucial for obese women.. · Physical inactivity and unemployment are associated with inappropriate gestational weight gain.. · Nutritional counseling is associated with appropriate gestational weight gain in women with BMI ≥40..

Abstract
OBJECTIVE To study the association between nicotine or cannabis metabolite presence in maternal urine and child neurodevelopmental outcomes. METHODS We conducted a secondary analysis of two parallel multicenter randomized controlled trials of treatment for hypothyroxinemia or subclinical hypothyroidism among pregnant individuals enrolled at 8-20 weeks of gestation. All maternal-child dyads with a maternal urine sample at enrollment and child neurodevelopmental testing were included (N=1,197). Exposure was urine samples positive for nicotine (cotinine) or cannabis 11-nor-9-carboxy-delta-9-tetrahydrocannabinol [THC-COOH]) or both metabolites. Primary outcome was child IQ at 60 months. Secondary outcomes included cognitive, motor and language, attention, behavioral and social competency, and differential skills assessments at 12, 24, 36, and 48 months. Quantile regression analysis was performed with confounder adjustment. RESULTS Of 1,197 pregnant individuals, 99 (8.3%) had positive cotinine samples and 47 (3.9%) had positive THC-COOH samples; 33 (2.8%) were positive for both. Groups differed in self-reported race and ethnicity, education, marital status, insurance, and thyroid status. Median IQ was similar between cotinine-exposed and -unexposed children (90 vs 95, adjusted difference in medians -2.47, 95% CI -6.22 to 1.29) and THC-COOH-exposed and -unexposed children (89 vs 95, adjusted difference in medians -1.35, 95% CI -7.76 to 5.05). In secondary outcome analysis, children with THC-COOH exposure compared with those unexposed had higher attention scores at 48 months of age (57 vs 49, adjusted difference in medians 6.0, 95% CI 1.11-10.89). CONCLUSIONS Neither prenatal nicotine nor cannabis exposure was associated with a difference in IQ. Cannabis exposure was associated with worse attention scores in early childhood. Longitudinal studies assessing associations between child neurodevelopmental outcomes and prenatal nicotine and cannabis exposure with a focus on timing and quantity of exposure are needed.

Abstract
OBJECTIVE We sought to determine if there is an association between fibroblast growth factor 21 (FGF21) levels and a history of gestational diabetes mellitus (GDM) in women with and without metabolic dysfunction, defined as a diagnosis of metabolic syndrome or type 2 diabetes (T2DM), 5 to 10 years following participation in a multiple cohort GDM study. STUDY DESIGN At 5 to 10 years after index pregnancy, women underwent a follow-up visit and were categorized as having no metabolic syndrome, metabolic syndrome, or T2DM. FGF21 levels were compared between women who did and did not have a history of GDM using multivariable linear regression. RESULTS Among 1,889 women, 950 underwent follow-up and 796 had plasma samples analyzed (413 GDM and 383 non-GDM). Total 30.7% of women had been diagnosed with T2DM or metabolic syndrome. Overall, there was no difference in median FGF21 levels in pg/mL between the prior GDM and non-GDM groups (p = 0.12), and the lack of association was observed across all three metabolic categories at follow-up (p for interaction = 0.70). CONCLUSION There was no association between FGF21 levels and prior history of mild GDM in women with and without metabolic dysfunction 5 to 10 years after the index pregnancy (ClinicalTrials.gov number, NCT00069576, original trial).

OBJECTIVE This study aimed to evaluate maternal and neonatal outcomes by method of cervical ripening for labor induction among low-risk nulliparous individuals. STUDY DESIGN This is a secondary analysis of a multicenter randomized trial of labor induction at 39 weeks versus expectant management in low-risk nulliparous participants. Participants undergoing cervical ripening for labor induction in either group were included. Participants were excluded for preripening membrane rupture, abruption, chorioamnionitis, fetal demise, or cervical dilation ≥3.5 cm. Cervical ripening was defined by the initial method used: prostaglandin only (PGE; referent), Foley with concurrent prostaglandin (Foley-PGE), Foley only (Foley), and Foley with concurrent oxytocin (Foley-oxytocin). Coprimary outcomes were adverse maternal and neonatal composites. Secondary outcomes included cesarean delivery and length of labor and delivery (L&D) stay. Multivariable analysis was used to adjust for patient characteristics. RESULTS Of 6,106 participants included in the trial, 2,376 (38.9%) met criteria for this analysis. Of these, 1,247 (52.4%) had cervical ripening with PGE, 290 (12.2%) had Foley-PGE, 385 (16.2%) had Foley, and 454 (19.1%) had Foley-oxytocin. The maternal composite outcome was similar among participants who received Foley-PGE (24.1%, adjusted relative risk [aRR] = 1.21, 95% confidence interval [CI]: 0.96-1.52), Foley (21.3%, aRR = 1.16, 95% CI: 0.92-1.45), or Foley-oxytocin (19.4%, aRR = 1.04, 95% CI: 0.83-1.29), compared with PGE (19.7%). The neonatal composite outcome was less frequent in participants who received the Foley-PGE (2.4%, aRR = 0.35, 95% CI: 0.16-0.75) or Foley (3.6%, aRR = 0.51, 95% CI: 0.29-0.89) but did not reach statistical significance for participants who received Foley-oxytocin (4.6%, aRR = 0.63, 95% CI: 0.40-1.01) compared with PGE only (6.8%). Participants who received Foley-PGE or Foley-oxytocin had a shorter L&D stay (adjusted mean difference = -1.97 hours, 95% CI: -3.45 to -0.49 and -5.92 hours, 95% CI: -7.07 to -4.77, respectively), compared with PGE. CONCLUSION In term low-risk nulliparous participants, Foley alone or concurrent with PGE is associated with a lower risk of adverse neonatal outcomes than with PGE alone. Length of L&D stay was the shortest with concurrent Foley-oxytocin. KEY POINTS · Adverse maternal outcomes are similar among different methods of cervical ripening in low-risk women.. · Adverse neonatal outcomes are less frequent with use of Foley alone or in combination with PGE.. · The use of Foley alone, or in combination with other agents, appears to be beneficial..

Abstract
OBJECTIVE The aim of the study is to evaluate the association between amniotomy at various time points during labor induction and maternal and neonatal outcomes among term, nulliparous women. STUDY DESIGN Secondary analysis of a randomized trial of term labor induction versus expectant management in low-risk, nulliparous women (2014-2017) was conducted. Women met inclusion criteria if they underwent induction ≥38 weeks' gestation using oxytocin with documented time and type of membrane rupture. Women with antepartum stillbirth or fetal anomaly were excluded. The primary outcome was cesarean delivery. Secondary outcomes included maternal and neonatal complications. Maternal and neonatal outcomes were compared among women with amniotomy versus women with intact membranes and no amniotomy at six 2-hour time intervals: before oxytocin initiation, 0 to <2 hours after oxytocin, 2 to <4 hours after, 4 to <6 hours after, 6 to <8 hours after, and 8 to <10 hours after. Multivariable logistic regression adjusted for maternal age, body mass index, race/ethnicity, modified Bishop score on admission, treatment group, and hospital (as a random effect). RESULTS Of 6,106 women in the parent trial, 2,854 (46.7%) women met inclusion criteria. Of these 2,340 (82.0%) underwent amniotomy, and majority of the women had amniotomy performed between 2 and <6 hours after oxytocin. Cesarean delivery was less frequent among women with amniotomy 6 to <8 hours after oxytocin compared with women without amniotomy (21.9 vs. 29.7%; adjusted odds ratio 0.61, 95% confidence interval 0.42-0.89). Amniotomy at time intervals ≥4 hours after oxytocin was associated with lower odds of labor duration >24 hours. Amniotomy at time intervals ≥2 hours and <8 hours after oxytocin was associated with lower odds of maternal hospitalization >3 days. Amniotomy was not associated with postpartum or neonatal complications. CONCLUSION Among a contemporary cohort of nulliparous women undergoing term labor induction, amniotomy was associated with either lower or similar odds of cesarean delivery and other adverse outcomes, compared with no amniotomy.

Abstract
BACKGROUND Primary cytomegalovirus (CMV) infection during pregnancy carries a risk of congenital infection and possible severe sequelae. There is no established intervention for preventing congenital CMV infection. METHODS In this multicenter, double-blind trial, pregnant women with primary CMV infection diagnosed before 24 weeks' gestation were randomly assigned to receive a monthly infusion of CMV hyperimmune globulin (at a dose of 100 mg per kilogram of body weight) or matching placebo until delivery. The primary outcome was a composite of congenital CMV infection or fetal or neonatal death if CMV testing of the fetus or neonate was not performed. RESULTS From 2012 to 2018, a total of 206,082 pregnant women were screened for primary CMV infection before 23 weeks of gestation; of the 712 participants (0.35%) who tested positive, 399 (56%) underwent randomization. The trial was stopped early for futility. Data on the primary outcome were available for 394 participants; a primary outcome event occurred in the fetus or neonate of 46 of 203 women (22.7%) in the group that received hyperimmune globulin and of 37 of 191 women (19.4%) in the placebo group (relative risk, 1.17; 95% confidence interval [CI] 0.80 to 1.72; P = 0.42). Death occurred in 4.9% of fetuses or neonates in the hyperimmune globulin group and in 2.6% in the placebo group (relative risk, 1.88; 95% CI, 0.66 to 5.41), preterm birth occurred in 12.2% and 8.3%, respectively (relative risk, 1.47; 95% CI, 0.81 to 2.67), and birth weight below the 5th percentile occurred in 10.3% and 5.4% (relative risk, 1.92; 95% CI, 0.92 to 3.99). One participant in the hyperimmune globulin group had a severe allergic reaction to the first infusion. Participants who received hyperimmune globulin had a higher incidence of headaches and shaking chills while receiving infusions than participants who received placebo. CONCLUSIONS Among pregnant women, administration of CMV hyperimmune globulin starting before 24 weeks' gestation did not result in a lower incidence of a composite of congenital CMV infection or perinatal death than placebo.

Intrapartum opioid analgesia and childhood neurodevelopmental outcomes among infants born preterm. Am J Obstet Gynecol MFM 2021; 3:100372.

Abstract
BACKGROUND There are concerns regarding neurobehavioral changes in infants exposed to parenteral opioids during labor; however, long-term neurodevelopment remains unstudied. OBJECTIVE We aimed to examine the association between parenteral opioids used as labor analgesia and perinatal outcomes and childhood neurodevelopment until 2 years of age among infants born prematurely. We hypothesized that intrapartum exposure to parenteral opioids is associated with impaired neurodevelopment and adverse perinatal outcomes. STUDY DESIGN This was a secondary analysis of a multicenter, randomized controlled trial assessing magnesium for the prevention of cerebral palsy in infants at risk for preterm birth. Women delivering a singleton, nonanomalous, live infant before 37 weeks' gestation were considered for inclusion. Women were excluded if they had missing exposure or primary outcome data, were exposed to general anesthesia, or reported use of heroin or unspecified illicit drugs. Women reporting use of nonopioid illicit drugs such as cocaine and marijuana were not excluded. Groups were compared based on exposure or nonexposure to parenteral opioids (intravenous or intramuscular) used as labor analgesia. The primary outcome was any psychomotor or mental developmental delay at 24 months according to the Bayley Scales of Infant Development II. Secondary outcomes were the Bayley Scales of Infant Development II subdomains and adverse perinatal outcomes. Multivariable logistic regression models were performed and adjusted odds ratios with 95% confidence intervals were estimated. RESULTS Of the 1404 women included, 535 (38%) received parenteral opioids as labor analgesia. Women receiving parenteral opioids were more likely to be younger, Hispanic, and present with cervical dilation ≥4 cm. Parenteral opioid recipients had lower rates of illicit nonopioid drug or tobacco use, a lower rate of cesarean delivery, lower educational level and were less likely to be undergoing induction. Women receiving parenteral opioids who underwent cesarean delivery were less likely to do so because of a nonreassuring fetal status. In the unadjusted and adjusted analyses, there were no significant differences in the primary outcomes of psychomotor or mental developmental delay at 2 years of age (adjusted odds ratio, 0.96; confidence interval, 0.76-1.20). The only significant difference in secondary outcomes was a shorter O2 requirement duration in the parenteral opioid group (2 vs 4 days; P=.002). CONCLUSION Among a population of preterm infants vulnerable to neurologic impairment, intrapartum exposure to parenteral opioids was not associated with an increased risk for neurodevelopmental delay up to 2 years of age, nor did these infants have worse perinatal outcomes.
