Objective The aim of the study is to determine the relation between education and adverse outcomes in individuals with pregestational or gestational diabetes. Study Design This population-based cohort study, using the U.S. vital statistics datasets, evaluated individuals with pregestational or gestational diabetes who delivered between 2016 and 2019. The primary outcome was composite neonatal adverse outcome including any of the following: large for gestational age (LGA), Apgar's score 6 hours, neonatal seizure, or neonatal death. The secondary outcome was composite maternal adverse outcomes including any of the following: admission to intensive care unit, transfusion, uterine rupture, or unplanned hysterectomy. Multivariable analysis was used to estimate adjusted relative risks (aRR) and 95% confidence intervals (CIs). Results Of 15,390,962 live births in the United States, 858,934 (5.6%) were eligible for this analysis. Compared with individuals with a college education and above, the risk of composite neonatal adverse outcome was higher in individuals with some college (aRR = 1.08, 95% CI = 1.07–1.09), high school (aRR = 1.06, 95% CI = 1.04–1.07), and less than high school (aRR = 1.05, 95% CI = 1.03–1.07) education. The components of composite neonatal adverse outcome that differed significantly between the groups were LGA, Apgar's score 6 hours. Infant death differed when stratified by education level. An increased risk of composite maternal adverse outcome was also found with a lower level of education. Conclusion Among individuals with diabetes, lower education was associated with a modestly higher risk of adverse neonatal and maternal outcomes. Key Points Education levels were associated with adverse outcomes among individuals with diabetes. Lower education is associated with multiple neonatal complications, including infant death. Individuals with varying levels of education are at higher risk for adverse maternal outcomes. [ABSTRACT FROM AUTHOR]

Objective  This study aimed to assess the risk of adverse outcomes among low-risk pregnancies at 39 to 41 weeks, stratified by birth weight percentile. Study Design  This retrospective cohort study utilized the U.S. vital statistics datasets (2013–2017) and evaluated low-risk women with nonanomalous cephalic singleton gestations who labored and delivered at 39 to 41 weeks, regardless of ultimate mode of delivery. Newborns were categorized as small (<10th percentile), large (>90th percentile), or appropriate (10–90th percentile) for gestational ages (SGA, LGA, and AGA, respectively). The primary outcome, composite neonatal adverse outcome (CNAO), included Apgar's score <5 at 5 minutes, assisted ventilation >6 hours, seizure, or neonatal death. The secondary outcome, composite maternal adverse outcome (CMAO), included intensive care unit admission, blood transfusion, uterine rupture, or unplanned hysterectomy. Multivariable Poisson's regression was used to estimate the association (using adjusted relative risk [aRR] and 95% confidence interval [CI]). Results  Of 19.8 million live births during the study interval, approximately 8.9 million (44.9%) met the inclusion criteria, with 9.9% being SGA, 9.2% being LGA, and 80.9% being AGA. SGA newborns delivered at 40 (aRR = 1.17; 95% CI: 1.12–1.23) and at 41 weeks (aRR = 1.55; 95% CI: 1.45–1.66) had a higher risk of CNAO than at 39 weeks. Similarly, LGA newborns delivered at 40 (aRR = 1.13; 95% CI: 1.07–1.19) and 41 weeks (aRR = 1.44; 95% CI: 1.35–1.54) and AGA newborns delivered at 40 (aRR = 1.24; 95% CI: 1.21–1.26) and 41 weeks (aRR = 1.57; 95% CI: 1.53–1.61) also had a higher risk of CNAO than at 39 weeks. CMAO was also significantly higher at 40 and 41 weeks than at 39 weeks, regardless of whether the mothers delivered SGA, LGA, or AGA newborns. Conclusion  Among low-risk pregnancies, the risks of composite neonatal and maternal adverse outcomes increase from 39 through 41 weeks' gestation, irrespective of whether newborns are SGA, LGA, or AGA.

Objective  This study aimed to compare morbidities among nonmacrosomic versus macrosomic singleton live births of nondiabetic women who labored. Study Design  This retrospective study utilized the 2003 revision of U.S. birth certificate data of singleton live births (2011–2013) at 37 to 41 weeks who labored. The primary outcomes were composite maternal and neonatal morbidities (CMM and CNM, respectively). We compared these outcomes by birth weight, 2,500 to 3,999 g (group 1; reference), 4,000 to 4,449 g (group 2), and 4,500 to 5,999 g (group 3). We used multivariable Poisson regression analyses to examine the association between birth weight groups and the outcomes. Results  Among 6,691,338 live births, 92.0% were in group 1, 7.1% in group 2, and 0.9% in group 3. The overall CMM and CNM rates were 4.4 and 6.8 per 1,000 live births, respectively. Compared with group 1, the risk of CMM was significantly higher in group 2 (adjusted risk ratio [aRR] = 1.50; 95% confidence interval [CI]: 1.44–1.56) and group 3 (aRR = 2.00; 95% CI: 1.82–2.19). Likewise, the risk of CNM was significantly higher in group 2 (aRR = 1.38; 95% CI: 1.33–1.43) and group 3 (aRR = 2.57; 95% CI: 2.40–2.75) than in group 1. Conclusion  Nondiabetic women who labor with a macrosomic newborns have a significantly higher rate of adverse outcomes than nonmacrosomic. [ABSTRACT FROM AUTHOR]

Objective  Late preterm births (delivery at 34–36 weeks) account for nearly three quarters of the preterm births and among them there is a knowledge gap about an important aspect of infant care: breast versus formula feeding. The aim of this study was to assess factors associated with formula feeding in late preterm neonates. Study Design  Secondary analysis of a multicenter randomized trial of antenatal corticosteroids for women at risk for late preterm birth. All women with a singleton pregnancy who delivered at 34 0/7 to 36 6/7 weeks were included. Women with no information on neonatal feeding or known fetal anomalies were excluded. The outcome evaluated was the type of neonatal feeding during hospital stay. Maternal and neonatal characteristics were compared among women who initiated breast versus formula feeding. Adjusted relative risks (aRRs) for formula feeding with 95% confidence intervals (CIs) were calculated. Results  Of the 2,831 women in the parent trial, 2,329 (82%) women met inclusion criteria and among them, 696 (30%) were formula feeding. After multivariable regression, the following characteristics were associated with an increased risk of formula feeding: maternal age < 20 years (aRR: 1.47, 95% CI: 1.20–1.80) or ≥35 years (aRR: 1.19, 95% CI: 1.02–1.40), never married status (aRR: 1.39, 95% CI: 1.20–1.60), government-assisted insurance (aRR: 1.41, 95% CI: 1.16–1.70), chronic hypertension (aRR: 1.19, 95% CI: 1.01–1.40), smoking (aRR: 1.51, 95% CI: 1.31–1.74), cesarean delivery (aRR: 1.16, 95% CI: 1.03–1.32), and admission to neonatal intensive care unit (aRR: 1.31, 95% CI: 1.16–1.48). Hispanic ethnicity (aRR: 0.78, 95% CI: 0.64–0.94), education >12 years (aRR: 0.81, 95% CI 0.69–0.96), and nulliparity (aRR 0.71, 95% CI: 0.62–0.82) were associated with a reduced risk for formula feeding. Conclusion  In this geographically diverse cohort of high-risk deliveries, 3 out 10 late preterm newborns were formula fed. Smoking cessation was a modifiable risk factor that may diminish the rate of formula feeding among late preterm births. Key Points Three of ten late preterm do not benefit from breastfeeding. Demographic characteristics are associated with type of feeding. Smoking cessation may improve the rate of breastfeeding. [ABSTRACT FROM AUTHOR]

Objective  This study aimed to compare the maternal and neonatal adverse outcomes among singletons delivered at 36 weeks or later with cerclage during index pregnancy versus those without cerclage. Study Design  This retrospective cohort study utilized the U.S. vital statistics datasets from 2011 to 2013. Inclusion criteria were women with nonanomalous singletons, with and without cerclage placement, without diabetes or hypertensive disorders, and delivered at 36 to 41 weeks. The coprimary outcomes were composite maternal and neonatal adverse outcomes. Composite maternal adverse outcome included admission to intensive care unit, maternal transfusion, ruptured uterus, unplanned hysterectomy, or unplanned operating room procedure. Composite neonatal adverse outcome included Apgar score less than 5 at 5 minutes, assisted ventilation for more than 6 hours, neonatal seizure, birth injury, or neonatal death. Secondary outcomes were chorioamnionitis and cesarean delivery. Multivariable Poisson's regression models with error variance were used while adjusting for confounders. Adjusted relative risk (aRR) with 95% confidence intervals (CIs) were calculated. Results  Of the 8,508,228 women who met inclusion criteria, 0.2% had a cerclage and reached 36 weeks. Composite maternal (aRR: 2.04; 95% CI: 1.76–2.36) and neonatal (aRR: 1.28; 95% CI: 1.11–1.47) adverse outcomes were significantly higher among those with cerclage than those without cerclage. Chorioamnionitis (aRR: 1.47; 95% CI: 1.30–1.67) and cesarean delivery (aRR: 1.10; 95% CI: 1.08–1.12) were also significantly higher in women with cerclage than those without cerclage. Conclusion  There is an association between increased composite maternal and neonatal adverse outcomes among women with cerclage who delivered at 36 to 41 weeks as compared with those without cerclage. Key Points Cerclage is associated with increased composite maternal adverse outcome in women at 36–41 weeks. Cerclage is associated with increased composite neonatal adverse outcome in women at 36–41 weeks. Increased chorioamnionitis and cesarean delivery rates are associated with cerclage in women at 36–41 weeks. [ABSTRACT FROM AUTHOR]

Objective We assessed the association among gestational age (GA) at birth, timing of death, and risk status of the pregnancy and racial/ethnic disparities in infant mortality rate in the United States. Study Design We utilized U.S. 2000 to 2004 birth cohort-linked birth and infant death data restricted to nonanomalous singleton live births. Multivariable log-binomial regression models were fit to evaluate racial/ethnic disparities in infant mortality while adjusting for potential confounders. Results Compared with whites, blacks had a higher adjusted infant mortality rate (IMR) (risk ratio [RR] 1.96, 95% confidence interval [CI] 1.91, 2.01), and Hispanics had a lower adjusted IMR (RR 0.79, 95% CI 0.76, 0.82). When categorized by GA, at 24 to 31 weeks, the adjusted early neonatal mortality (ENM) is significantly lower for black than whites, similar at 32 to 36 weeks, and at 37 weeks or more, blacks have significantly higher ENM. Conclusions The racial/ethnic disparities in infant mortality in the United States persist and vary across GA. These disparities may largely be driven by the excess post-neonatal deaths among blacks.

Objective  To evaluate the degree of adherence to the new the American College of Obstetricians and Gynecologists/Society for Maternal–Fetal Medicine guidelines in labor arrest management. Study Design  A retrospective study of term, live, singleton deliveries with intrapartum primary cesarean delivery solely for failed induction of labor or labor arrest. Adherence was defined according to the Safe Prevention of the Primary Cesarean Delivery 2014 criteria. We evaluated adherence and compared maternal and perinatal outcomes, delivery time frame, and billing provider. Multivariable Poisson regression models with robust error variance were used to calculate adjusted relative risk (aRR) and 95% confidence interval (CI). Results  Two-hundred six deliveries met the inclusion criteria; 73% were deemed not adherent to the guidelines. The majority of cases were under the care of nonacademic private practice OB/GYN physicians. The adherence rate was higher in the active phase of labor (45%) than in second stage (17%) and latent phase (14%). There were no differences in perinatal outcomes between the two groups. The adherence to guidelines was higher among academic OB/GYN physicians (aRR, 2.24, 95% CI, 1.49–3.36) and during the weekday–night shift (aRR, 1.81, 95% CI, 1.10–2.98). Conclusion  Despite recent guidelines aimed to reduce the primary cesarean delivery rate, most cesarean deliveries performed for labor arrest disorders were not adherent to the guidelines.

Objective In an effort to reduce the primary cesarean delivery (CD) rate, the American College of Obstetricians and Gynecologists (ACOG) recommended new labor guidelines in 2014 that allow longer duration of labor times. There are little data on the impact of these guidelines on CD rates and pregnancy outcomes in a predominantly Hispanic population. This study aimed to compare the primary CD rates and maternal and neonatal outcomes in patients undergoing primary CD for arrest of labor before and after implementation of the 2014 guidelines. Study Design This was a retrospective cohort study of term patients who underwent a CD for an arrest disorder between January 2011 and April 2017 at a county teaching hospital. Our primary outcome was the composite maternal and neonatal morbidities (CMM and CNM, respectively). Differences in the demographic and clinical characteristics, CMM, and CNM stratified by time period (pre- vs. postimplementation) were examined. Results There were 4,976 deliveries in the study period: 525 (11%) underwent primary CD for arrest disorder; 298 (6%) prior to 2014, and 227 (5%) after 2014 (p = 0.62). There was no significant difference in the rate of CD between the two periods (13.4 vs. 13.3%, p = 0.81). In patients undergoing CD for arrest of dilation (n = 389), the CMM and CNM did not significantly change between both groups (63.3 vs. 56%, p = 0.15). In patients who had a CD for arrest of descent (n = 136), the rate of CMM significantly increased from 50 to 75% (p = 0.02) with no significant change in the CNM (13.2 vs. 20%, p = 0.3). Conclusion Despite significant changes in labor management after the publication of the 2014 guidelines, our primary CD rate was not reduced, and we noticed an increase in CMM in patients who had CD for arrest of descent. A randomized controlled trial is needed to further evaluate the effect of these guidelines nationally. Key Points The Obstetric Care Consensus statement aims to decrease the rate of cesarean delivery (CD). We observed an increase in morbidity in CD if done for arrest of descent (pre/post the consensus). A randomized controlled trial is needed to further assess the impact of the guidelines on morbidity.

Objective  Women with placenta accreta spectrum (PAS) having an unplanned delivery may have worse outcome compared with women with a planned delivery. The primary objective of this study was to compare severe maternal morbidity among women with PAS who had a planned scheduled delivery versus an unplanned delivery. Secondary objective was to compare neonatal outcomes. Study Design  Retrospective cohort study at two tertiary centers (January 2009 to June 2019) of all women who underwent a hysterectomy with a histologic proven PAS. Primary outcome was severe maternal morbidity which defined as any of the following: transfusion of ≥4 RBC units or ureter/bowel injury. Neonatal outcome was a composite neonatal morbidity defined as any of the following: Apgar score's < 5 at 5 minutes, mechanical ventilation, or respiratory distress syndrome. Maternal demographic, clinical, and sonographic characteristics were compared between the two groups (planned vs. unplanned). Descriptive statistics were used as appropriate, and a statistical significance was established if p -value was < 0.05. Results  Of 109 women who underwent cesarean hysterectomy for PAS, 41 (37.6%) had an unplanned delivery. There was no significant difference in the number of previous cesarean deliveries or ultrasound findings between the two groups. Women with an unplanned delivery were more likely to bleed during pregnancy than those that had a planned delivery (p  = 0.04). Women with unplanned delivery had lower gestational age at delivery (30.3 vs. 33.8 weeks, p  = 0.001) had a 75% higher rate of the primary outcome (63 vs. 36%, p  = 0.007) and had a higher rate of intensive care unit admissions (39 vs. 17.7%, p  = 0.01) compared with women with a planned delivery. The neonatal morbidity did not differ between the two groups. Conclusion  Since unplanned cesarean hysterectomy among women with PAS occurs in 40% and is associated with significantly higher morbidity, interventions are needed to mitigate the rate of adverse outcomes. Key Points Only 60% of women with PAS reached planned delivery at 34 weeks. PAS unplanned delivery is associated with high morbidity. Some women with PAS may need a scheduled earlier delivery.

Objective We aimed to compare the rates of wound separation (WS) and surgical site infection (SSI) after cesarean delivery (CD) by a single surgeon. Pfannenstiel skin incision (PSI) was closed with Dermabond, staples, or suture. Study Design Retrospectively all women having CD via PSI were identified.WS and SSI rates with Dermabond were compared with other two techniques. Results Of 239 CDs performed, 88% (n = 211) were available for postpartum evaluation. The PSI was closed with Dermabond in 85 (40%), staples in 76 (36%), and suture in 50 (24%). Overall WS rate was 7%; with Dermabond, it was 5% versus 13% with staple (p = 0.090) and 2% with suture (p = 0.651). Post hoc calculation suggests a randomization of 4325 women is needed to determine if Dermabond has one-third less wound complication than suture. Conclusion For the PSI closure, Dermabond may be a useful alternative skin closure device, though a randomized trial is warranted. [ABSTRACT FROM AUTHOR]

Objective  To determine whether basal insulin analogs reduce the rate of composite neonatal morbidity compared with neutral protamine Hagedorn (NPH) in women with type 2 diabetes mellitus (T2DM). Study Design  This was a retrospective cohort study of women with T2DM and singleton pregnancy at a single tertiary center. Primary outcome was a composite neonatal morbidity of any of the following: shoulder dystocia, large for gestational age, neonatal intensive care unit admission, neonatal hypoglycemia, or respiratory distress syndrome. Secondary outcomes were rates of maternal hypoglycemic events, hypertensive disorders, preterm birth, and primary cesarean delivery. Adjusted relative risk (aRR) and 95% confidence intervals (CI) were calculated. Results  Of 233 women with T2DM that met the inclusion criteria, 114 (49%) were treated with basal insulin analogs and 119 (51%) with NPH. The rate of composite neonatal morbidity was similar between groups (73 vs. 60%; aRR: 1.18; 95% CI: 0.92–1.51). There were no differences in the rates of maternal adverse outcomes between the groups. Basal insulin analog was associated with a lower rate of primary cesarean delivery as compared with NPH (21 vs. 36%; aRR: 0.44; 95% CI: 0.25–0.78). Conclusion  Among pregnant women with T2DM managed with either basal or NPH insulin regimen, the rates of composite neonatal morbidity and maternal complications were similar. [ABSTRACT FROM AUTHOR]

Objective This article aims to compare the composite maternal and neonatal morbidities (CMM and CNM, respectively) between macrosomic (≥4,000 g) and nonmacrosomic (<4,000 g) newborns among women with diabetes mellitus (DM). Methods Maternal demographic and peripartum outcome data (N = 1,260) were collected from a retrospective cohort. CMM included chorioamnionitis/endometritis, wound infection, shoulder dystocia, eclampsia, pulmonary edema, admission for hypoglycemia, 3rd/4th degree perineal laceration, and death.CNMincluded 5-minute Appearance, Pulse, Grimace, Activity and Respiration (APGAR) score of <4, neonatal intensive care unit (NICU) admission, respiratory distress syndrome, mechanical ventilation, intraventricular hemorrhage grade III/IV, necrotizing enterocolitis stage II/III, hypoglycemia, hypocalcemia, bronchopulmonary dysplasia, sepsis, seizures, hyperbilirubinemia, and death.Multivariable Poisson regression models with robust error variance were used to calculate adjusted relative risk (aRR) and 95% confidence interval (CI). Results The study population consisted of 967 subjects, including 854 (88.3%) nonmacrosomic and 113 (11.7%) macrosomic infants. After adjustment, the risk of CMMwas higher amongmacrosomic deliveries (aRR = 4.08, 95% CI = 2.45-6.80). The risk of CNM was also higher among macrosomic deliveries (aRR = 1.77, 95% CI = 1.39-2.24). Macrosomia was associated with an increased risk in NICU admission, hypoglycemia, and hyperbilirubinemia. Conclusion Among DM deliveries, macrosomia was associated with a fourfold higher risk of CMM and almost twofold higher risk of CNM. [ABSTRACT FROM AUTHOR]
