Abstract
OBJECTIVE Hypertensive disorders of pregnancy (HDP) are common complications associated with severe maternal and neonatal morbidity. One goal of prenatal care, especially at term, is to screen for HDP. As treatment of HDP centers on delivery when appropriate, timely diagnosis is crucial. We postulated that reduced in-person visits during the COVID-19 pandemic may have resulted in delayed diagnosis of HDP with concomitant higher rates of maternal morbidity. We sought to investigate the prevalence of HDP during the COVID-19 pandemic, as well as median gestational age at time of delivery as compared to the pre-pandemic median. STUDY DESIGN This was a retrospective cohort analysis comparing singleton deliveries at four large volume hospitals during the COVID-19 pandemic (April - July 2020 during a statewide "stay-at-home" order) to those in a pre-COVID era (April - July 2019). Deliveries complicated by HDP were identified by ICD-10 codes. Rates of HDP and markers of severe disease were the primary outcomes compared between the groups; multivariate regression was used to calculate the odds ratio of severe disease among women with any diagnosis of HDP. RESULTS The cohort included 9,974 deliveries: 5,011 in 2020 and 4,963 in 2019. Patient characteristics (age, body mass index, race, ethnicity, and insurance type) did not differ significantly between the groups. There was an increase in hypertensive disorders of pregnancy during the COVID era (9.0% vs. 6.9%; p<0.01), which was significant even when controlling for patient parity (OR 1.41, 95% CI 1.20-1.66). Among women with HDP, gestational age at delivery did not differ between the cohorts, nor did the proportion of patients with severe disease. CONCLUSION We found a statistically significant increase in the rate of HDP during the COVID-19 pandemic. However, there was no change in the proportion of severe disease, suggesting that this increase did not significantly impact clinical morbidity.

Abstract
Importance The publication of the Antenatal Late Preterm Steroids (ALPS) trial in February 2016 demonstrated that antenatal administration of betamethasone in the late preterm period (between 34 to 36 weeks of gestation) for individuals with a high risk of delivery decreased neonatal respiratory morbidity. National estimates have suggested the trial did change obstetric practice, but little is known if the evidence was adopted uniformly or equitably. Objective To assess regional variation in the use of late preterm steroids after the publication of the Antenatal Late Preterm Steroids (ALPS) Trial and to understand factors associated with a region's pace of adoption. Design, Setting, and Participants This cross-sectional study used US natality data from February 2015 to October 2017 from hospital referral regions (HRRs) within the US. Inclusion criteria included live-born, nonanomalous, singleton, late preterm (34 to 36 completed weeks of gestation) neonates born to individuals without pregestational diabetes. This study was conducted from November 15, 2022, to January 13, 2023. Main Outcome and Measures HRRs were categorized as either a slower adopter or faster adopter of antenatal late preterm steroids based on the observed vs expected pace of antenatal steroid adoption in a 1-year period after the trial's dissemination. Patient and regional factors hypothesized a priori to be associated with the uptake of late preterm steroids were compared between faster and slower adopters. Comparisons were made using Student t test or Wilcoxon rank-sum test, as appropriate. A multivariable logistic regression was constructed to identify factors associated with faster adopter status in the postperiod. Results There were 666 097 late preterm births in 282 HRRs. The mean (SD) maternal age in HRRs was 27.9 (1.2) years. The median (IQR) percentage of births by race categories in HRRs for patients identifying as American Indian or Alaskan Native was 0.5% (0.2%-1.3%); Asian or Pacific Islander, 3.0% (1.7%-5.3%); Black, 12.9% (5.1%-29.1%); and White, 78.6% (66.6%-87.0%). The median percentage of births in HRRs to patients of Hispanic ethnicity was 11.2% (6.3%-27.4%). In this study, 136 HRRs (48.2%) were classified as faster adopters and 146 (51.8%) were classified as slower adopters. Faster adopters increased their steroid use by 12.1 percentage points (from 5.9% to 18.0%) compared with a 5.5 percentage point increase (from 3.7% to 9.2%) among slower adopters (P < .001). Most examined patient and regional factors were not associated with a region's pace of adoption, with the exception of the regional prevalence of prior preterm birth (adjusted odds ratio [aOR], 2.04 [95% CI, 1.48-2.82]) and the percentage of deliveries at 34 to 35 weeks of gestation (aOR, 0.68 [95% CI, 0.47-0.99]) compared with 36 weeks. Conclusions and Relevance In this cross-sectional study, there was widespread geographic variation in the adoption of antenatal steroid administration for late preterm births that largely remained unexplained by population factors. These findings should prompt further investigations to barriers to timely or equitable access to new evidence-based practices and guide future dissemination strategies with the goal of more uniform adoption.

Abstract
BACKGROUND Maternal cardiac arrest is a rare outcome, and thus there are limited opportunities for specialists in obstetrics and gynecology to acquire the skills required to respond to it through routine clinical practice. OBJECTIVE This study aimed to evaluate gaps in medical education in maternal cardiac arrest and whether a simulation-based training program improves resident knowledge and comfort in the diagnosis and treatment of maternal cardiac arrest. STUDY DESIGN A 2-hour training for obstetrics and gynecology residents at an academic medical center was conducted, consisting of a didactic presentation, defibrillator skills station, and 2 high-fidelity simulations. Consenting residents completed a 21-item pretest followed by a 12-item posttest exploring knowledge of and exposure to maternal cardiac arrest. The McNemar and Wilcoxon signed-rank tests were used to compare pre- and posttest data. RESULTS Of 21 residents, 15 (71.4%) had no previous education about maternal cardiac arrest, and 17 (81.0%) had never responded to a maternal code. Participants demonstrated increased knowledge about maternal cardiac arrest after the session, providing more correct answers on the reversible causes of pulseless electrical activity arrest (median 4 vs 7 correct responses; P<.01). After the training, more residents were able to identify the correct gestational age to perform a cesarean delivery during maternal cardiac arrest (19.0% vs 90.5%; P<.01) and the correct location for this procedure (52.4% vs 95.2%; P<.01). All residents reported that maternal cardiac arrest training was important and that they would benefit from additional sessions. Median composite comfort level in managing maternal cardiac arrest significantly increased after participation (pretest, 24.0 [interquartile range, 21.5-28.0]; posttest, 37.0 [interquartile range, 34.3-41.3]; P<.01). CONCLUSION Residents report limited exposure to maternal cardiac arrest and desire more training. Simulation-based training about maternal cardiac arrest is needed during residency to ensure that graduates are prepared to respond to this high-acuity event.

Abstract
BACKGROUND Obstetric anal sphincter injuries are associated with both short-term and long-term maternal morbidity. Antibiotic administration has been shown to decrease wound complications after obstetric anal sphincter injuries. However, the rate of antibiotic administration in a contemporary obstetrical population is not known. OBJECTIVE This study aimed to describe the rate of antibiotic administration for obstetric anal sphincter injuries, to characterize factors associated with antibiotic administration on the day of delivery among women with obstetric anal sphincter injuries, and to determine if there was an association between antibiotic administration and reduced wound complications. STUDY DESIGN This was a retrospective cohort study of women with a singleton vaginal birth complicated by obstetric anal sphincter injuries between 2016 and 2021 in a single healthcare system. Information about any antibiotic administration on the day of delivery was collected. Information on wound complications (determined by International Classification of Disease, 10th Revision, codes) that occurred within the first 6 months postpartum were available for patients who delivered at tertiary-care centers. Multivariable logistic regression analysis was used to identify factors associated with antibiotic administration and the association between antibiotics and wound complications. RESULTS During the study period, 1550 women met the inclusion criteria of whom 855 (55.2%) received antibiotics. Antibiotic administration was higher at tertiary-care hospitals than at community-based hospitals (68.7 vs 26.8%; P<.001). In the adjusted analysis, antibiotic administration was higher among women with a fourth-degree laceration (adjusted odds ratio, 2.72; 95% confidence interval, 1.69-4.37) and lower among women of Asian or Pacific Islander heritage (adjusted odds ratio, 0.88; 95% confidence interval, 0.80-0.97). At tertiary-care hospitals, 43 women (4.1%) had a wound complication, and more than 80% of those presented within the first 2 weeks postpartum. Antibiotic use was associated with reduced rates of wound complications (adjusted odds ratio, 0.34; 95% confidence interval, 0.13-0.91). All patients received a regimen with gram-positive bacterial coverage; there was no association between type of antibiotic regimen administered and wound complications. CONCLUSION Any antibiotic administration on the day of delivery was associated with a decreased rate of wound complications after obstetric anal sphincter injuries. However, only about half of the women with obstetric anal sphincter injuries received antibiotics. Optimizing antibiotic administration may help to reduce the risk of complications in this population.

Abstract
BACKGROUND Guidelines support comparable treatment for women diagnosed with breast cancer during pregnancy (PrBC) and nonpregnant women with limited case-specific modifications to ensure maternal-fetal safety. Experience during pregnancy with modern agents, such as taxanes or granulocyte colony-stimulating factors (GCSF), is limited. PATIENTS AND METHODS We retrospectively identified a multi-institutional cohort of PrBC between 1996 and 2020. Propensity score analyses with multiple imputation for missing variables were applied to determine the associations between chemotherapy exposures during pregnancy, with or without taxanes or GCSF, and a compound maternal-fetal outcome including spontaneous preterm birth, preterm premature rupture of membranes, chorioamnionitis, small for gestational age newborns, congenital malformation, or 5-min Apgar score < 7. RESULTS Among 139 PrBC pregnancies, 82 (59.0%) were exposed to chemotherapy, including 26 (31.7%) to taxane and 18 (22.0%) to GCSF. Chemotherapy use, in general, and inclusion of taxane and/or GCSF, specifically, increased over time. Pregnancies resulting in live singleton births (n = 123) and exposed to chemotherapy were as likely to reach term as those that were not (59.5% vs. 63.6%, respectively, punadjusted = 0.85). Among women treated with chemotherapy, propensity score-matched odds ratios (OR) for the composite maternal-fetal outcome were not significantly increased with taxane (OR 1.24, 95% CI 0.27-5.72) or GCSF (OR 2.11, 95% confidence interval (CI) 0.48-9.22) with similar effects in multiple imputation and sensitivity models. CONCLUSION The judicious increased use of taxane chemotherapy and/or growth factor support during pregnancy was not associated with unfavorable short-term maternal-fetal outcomes. While these findings are reassuring, case numbers remain limited and continued surveillance of these patients and progeny is warranted.

Abstract
IMPORTANCE The Antenatal Late Preterm Steroids (ALPS) trial demonstrated a 20% reduction in the risk of respiratory complications in neonates at risk for a late-preterm birth who were exposed to antenatal corticosteroids compared with those who were not. OBJECTIVE To assess whether new evidence of steroid administration for neonatal respiratory benefit in the late-preterm period is associated with changes in obstetric practice and the use of assisted ventilation for the neonate after delivery. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study of US births from February 1, 2015, to October 31, 2017, as ascertained from US natality data, included live-born, singleton neonates born between 34 and 36 completed weeks of gestation to people without pregestational diabetes. An interrupted time series analysis using Poisson regression models was conducted. Data were analyzed from July 11, 2022, to November 9, 2022. EXPOSURES Public dissemination of the ALPS trial results, which occurred during a 9-month period from February 1, 2016 (first published online), to October 31, 2016 (time of the last major professional society's guideline update in the months after the trial's publication). MAIN OUTCOMES AND MEASURES Steroid use, any assisted ventilation use, and assisted ventilation use for more than 6 hours immediately after the dissemination period. RESULTS A total of 707 862 births were included, divided among the 12-month predissemination period (n = 250 643), dissemination period (n = 195 736), and 12-month postdissemination period (n = 261 493). Most births were at 36 weeks of gestation (53.9% in the predissemination and postdissemination period; P = .10). Small but significant differences were found between the predissemination and postdissemination period cohorts: there were more individuals 35 years or older (19.5% vs 17.9%), fewer White individuals (67.8% vs 69.8%), and more publicly insured individuals (50.5% vs 50.1%) in the postdissemination period compared with the predissemination period, respectively (P < .001 for all). Compared with what rates were expected based on the predissemination trends, the adjusted rate of steroid use increased from 5.0% to 11.7% (adjusted incidence rate ratio [IRR], 2.34; 95% CI, 2.13-2.57), and assisted ventilation use decreased from 8.9% to 8.2% (adjusted IRR, 0.91; 95% CI, 0.85-0.98) after the dissemination period. No change was observed in assisted ventilation use for more than 6 hours (adjusted IRR, 0.98; 95% CI, 0.87-1.10). CONCLUSIONS AND RELEVANCE These findings suggest that there was an immediate change in practice of administering antenatal steroids and a reduction in neonatal morbidity among late-preterm births associated with the dissemination of the ALPS trial, suggesting that this evidence may be translating into a reduction in immediate respiratory morbidity outside the context of a clinical trial.

Abstract
OBJECTIVE Breast cancer is one of the most frequently diagnosed cancers in pregnancy and is commonly treated with chemotherapy. To date, studies examining effects of chemotherapy during pregnancy on fetal growth have yielded conflicting results, and most are limited by small sample sizes or are nonspecific with respect to cytotoxic regimen or type of cancer treated. We sought to evaluate the effect of chemotherapy for breast cancer in pregnancy on birthweight and small for gestational age infants. STUDY DESIGN This is a retrospective cohort study of 74 women diagnosed with pathologically confirmed breast cancer during pregnancy between 1997 and 2018 at one of three academic medical centers, who had a singleton birth with known birthweight. Forty-nine received chemotherapy and 25 did not receive chemotherapy. Linear regression modeling was used to compare birthweight (by gestational age and sex-specific z-score) by chemotherapy exposure. Subanalyses of specific chemotherapy regimen and duration of chemotherapy exposure were also performed. Placental, neonatal, and maternal outcomes were also analyzed by chemotherapy exposure. RESULTS In the adjusted model, chemotherapy exposure was associated with lower birthweight (Δ z-score = -0.49, p = 0.03), but similar rates of small for gestational age (defined as birthweight <10th percentile for gestational age) infants (8.2 vs. 8.0%, p = 1.0; Fisher's exact test). Each additional week of chemotherapy (Δ z-score = -0.05, p = 0.03) was associated with decreased birthweight, although no association was found with specific chemotherapy regimen. Chemotherapy exposure was associated with lower median placental weight percentile by gestational age (9th vs. 75th, p < 0.05). Secondary maternal outcomes were similar between the group that did and did not receive chemotherapy. CONCLUSION Chemotherapy for breast cancer in pregnancy in this cohort is associated with lower birthweight but no difference in the rate of small for gestational age infants. KEY POINTS · Chemotherapy for breast cancer in pregnancy is associated with decreased birthweight but similar rates of small for gestational age infants.. · Birthweight did not differ according to chemotherapy regimen.. · There is no difference in the rate of small for gestational age infants..

Abstract
OBJECTIVE Preventing the first cesarean delivery (CD) is important as CD rates continue to rise. During the novel coronavirus disease 2019 (COVID-19) pandemic, quality improvement metrics at our hospital identified lower rates of CD. We sought to investigate this change and identify factors that may have contributed to the decrease. STUDY DESIGN We compared nulliparous singleton deliveries at a large academic hospital during the COVID-19 pandemic (April through July 2020 during a statewide "stay-at-home" order) to those in the same months 1 year prior to the pandemic (April through July 2019). The primary outcome, mode of delivery, was obtained from the electronic medical record system, along with indication for CD. RESULTS The cohort included 1,913 deliveries: 892 in 2019 and 1,021 in 2020. Patient characteristics (age, body mass index, race, ethnicity, and insurance type) did not differ between the groups. Median gestational age at delivery was the same in both groups. The CD rate decreased significantly during the COVID-19 pandemic compared with prior (28.9 vs. 33.6%; p = 0.03). There was a significant increase in the rate of labor induction (45.7 vs. 40.6%; p = 0.02), but no difference in the proportion of inductions that were elective (19.5 vs. 20.7%; p = 0.66). The rate of CD in labor was unchanged (15.9 vs. 16.3%; p = 0.82); however, more women attempted a trial of labor (87.0 vs. 82.6%; p = 0.01). Thus, the proportion of CD without a trial of labor decreased (25.1 vs. 33.0%; p = 0.04). CONCLUSION There was a statistically significant decrease in CD during the COVID-19 pandemic at our hospital, driven by a decrease in CD without a trial of labor. The increased rate of attempted trial of labor suggests the presence of patient-level factors that warrant further investigation as potential targets for decreasing CD rates. Additionally, in a diverse and medically complex population, increased rates of labor induction were not associated with increased rates of CD. KEY POINTS · Primary CD rate fell during COVID-19 pandemic.. · Decrease was driven by more women attempting labor.. · Higher rate of induction without rise in CD rate was found..

Abstract
OBJECTIVE This study was aimed to determine if admission-to-delivery times vary between term nulliparous women with prelabor rupture of membranes (PROM) who initially receive oxytocin compared with buccal misoprostol for labor induction. STUDY DESIGN This is a retrospective cohort of 130 term, nulliparous women with PROM and cervical dilation of ≤2 cm who underwent induction of labor with intravenous oxytocin or buccal misoprostol. The primary outcome was time from admission to delivery. Linear regressions with log transformation were used to estimate the effect of induction agent on time to delivery. RESULTS Women receiving oxytocin had faster admission-to-delivery times than women receiving misoprostol (16.9 vs. 19.9 hours, p = 0.013). There were no significant differences in secondary outcomes between the groups. In the adjusted model, women who received misoprostol had a 22% longer time from admission to delivery (95% CI 5.0-42.0%) compared with women receiving oxytocin. CONCLUSION In term nulliparous patients with PROM, intravenous oxytocin is associated with faster admission-to-delivery times than buccal misoprostol.

Abstract
Abstract
Background
BCP is uncommon; however, the frequency is increasing due to trends in delayed childbearing. Studies have suggested that some systemic therapies, including doxorubicin and cyclophosphamide, can be delivered safely during pregnancy after the first trimester, whereas agents such as trastuzumab and endocrine therapy are contraindicated due to risk to the fetus. Data remain limited on the efficacy and safety of administering taxane chemotherapy or growth factor support during pregnancy. We retrospectively evaluated the safety of systemic therapies, including paclitaxel and GCSF, as well as clinical outcomes, in a multi-institutional cohort of patients (pts) with BCP.
Methods
Pts treated for BCP from 1996-2018 from 3 large academic institutions were included. Demographic, oncologic treatment, and obstetric/neonatal outcomes data were obtained from medical records. Disease-free survival (DFS) and overall survival (OS) were estimated by Kaplan-Meier; Log-rank test were used to compare different groups/outcomes. Associations were calculated by Fisher's exact test.
Results
A total of 114 pts diagnosed with BCP were included. The median age was 35 years (range 25-44) and median gestational age at diagnosis was 18 weeks (range 2-38). BCP was predominantly early stage at diagnosis (stage I 28.0%, stage II 53.5%) and ER+/HER2- negative (48.2%). Sixty-three (55.2%) women received chemotherapy, 13 (11.4%) received paclitaxel and 11 (9.6%) GCSF (daily or depot injections) while pregnant. A total of 78% of pts with HER-2-positive BCP (28/36) received trastuzumab after delivery (11% were treated before 2005 and 5.5% were T1a). With median follow-up of 67.7 months, median DFS (stage I-III) was 212.8 months (CI 95% 108.4-317.1), and median OS (stage I-IV) was not reached. Subgroup analysis suggested a higher DFS for pts diagnosed in the 1sttrimester compared to the 3rdtrimester among women with stage II-III (HR 0.25 CI 95% 0.09-0.70, p= 0.03). Among women who received paclitaxel, there was no significant increase in adverse obstetrical/neonatal outcomes: preterm delivery (23.1% vs 13.1%, p 0.39), low weight newborn (7.7% vs 9.1 %, p 1.0), congenital malformations (0% vs 6.1%, p 1.0) or acute neonatal adverse outcomes (7.7% vs 4.0%, p 0.51), which include NICU need and Apgar 5'<7, compared to pts who did not receive paclitaxel. Among pts who received GCSF during pregnancy, adverse outcomes were numerically but not statistically higher than women who did not receive growth factor: preterm delivery (36.3% vs 11.0%, p 0.051), low weight newborn (27.3% vs 6.9%, p 0.058), congenital malformations (9.1% vs 1.0%, p 0.18) or acute neonatal adverse outcomes (18.2% vs 3.0%, p 0.07).
Conclusion
In this multi-institution cohort of BCP pts, despite a small number of pts, exposure to contemporary therapies including paclitaxel was not associated with unfavorable obstetrical/neonatal outcomes and these results suggest it is safe to administer during pregnancy under the care of a multidisciplinary team. Although not statistically significant, GCSF presented numerical worse outcomes and combining data from several cohorts would be helpful to provide confirmation of these findings.
