Abstract
OBJECTIVE The aim of this study was to compare duration of labor induction between diabetic and nondiabetic women receiving dinoprostone vaginal insert (10 mg). STUDY DESIGN This is a secondary analysis of two large randomized controlled trials using dinoprostone vaginal inserts for labor induction. We compare time to active labor, overall delivery, and vaginal delivery between diabetic and nondiabetic women undergoing induction of labor with a 10-mg dinoprostone vaginal insert. RESULTS Diabetic women receiving dinoprostone vaginal insert had a longer time to onset of active labor, overall delivery, and vaginal delivery than their nondiabetic counterparts. There was no difference in abnormal labor affecting fetal heart rate pattern in diabetic women compared with nondiabetic women. The rates of neonatal hyperbilirubinemia were higher in diabetic women. CONCLUSION Diabetes may represent an independent factor associated with prolonged induction among women undergoing induction of labor with dinoprostone. Dinoprostone is well tolerated in both diabetic and nondiabetic women. KEY POINTS · Diabetic women receiving DVI have slower labor curves than nondiabetic women.. · Nulliparous diabetic women took longer to achieve active labor, overall delivery, and vaginal delivery than nondiabetic women.. · Parous diabetic women took longer to achieve vaginal delivery than nondiabetic women..

Abstract
Importance The induction rate continues to increase in the United States placing pressure on the health care system with increasing cost and time spent on labor and delivery. Most labor induction regimens have evaluated uncomplicated singleton-term gestations. Unfortunately, the optimal labor regimens of medically complicated pregnancies have not been well described. Objective The aim of this study was to review the current available evidence regarding the various labor induction regimens and understand the evidence that exists for induction regimens in complicated pregnancies. Evidence Acquisition Data were acquired by a literature search on PubMed, ClinicalTrials.gov, the Cochrane Review database, the most recent American College of Obstetricians and Gynecologists practice bulletin on labor induction, and a review of the most recent edition on widely used obstetric texts for key words related to labor induction. Results Many heterogeneous clinical trials exist examining various labor induction regimens such as prostaglandin only, oxytocin only, or a combination of mechanical dilation with prostaglandins or oxytocin. Several Cochrane systematic reviews have been performed, which suggest a combination of prostaglandins and mechanical dilation results in an improved time to delivery when compared with single-use methods. Evaluating pregnancies complicated by maternal or fetal conditions, there exist retrospective cohorts describing significantly different labor outcomes. Although a few of these populations have planned or active clinical trials, most do not have an optimal labor induction regimen described. Conclusions and Relevance Most induction trials are significantly heterogeneous and limited to uncomplicated pregnancies. A combination of prostaglandins and mechanical dilation may result in improved outcomes. Complicated pregnancies have significantly different labor outcomes; however, almost none have well-described labor induction regimens.

Abstract
OBJECTIVE Rates of pregestational (PGDM) and gestational diabetes (GDM), and their associated pregnancy complications, are rising. Pregnancies complicated by diabetes have increased cesarean delivery (CD) rates; however, there are limited data regarding the current rates of, and contributing factors to, these deliveries. The Robson Ten Group Classification System (TGCS) is a clinically relevant, standardized framework that can be used to evaluate and analyze cesarean rates. The objective of this study was to evaluate rates of, and indications for, intrapartum, unplanned CD among pregnancies complicated by diabetes, compared to normoglycemic (NG) pregnancies, in a large United States birth cohort. METHODS This retrospective cohort study used chart-abstracted data on births between 24 and 42 weeks' gestation at 17 hospitals that contributed to the Obstetrical Care Outcome Assessment Program database between 01/2016 and 03/2019. The CD rate for NG pregnancies, and pregnancies complicated by gestational and PGDM was calculated and compared using the Robson TGCS. The indications for intrapartum CD in patients with term, singleton, vertex gestations without a prior cesarean were then analyzed. Univariate and multivariate logistic regression models were used to compare the cesarean rate and indications for CD, between the diabetic groups and the NG group. Results were adjusted for maternal age, BMI, neonatal birth weight, and insurance status, as well as clustering by hospital. RESULTS A total of 86,381 pregnant people were included in the study cohort. Of these 76,272 (88.3%) were NG, 8591 (9.9%) had GDM, and 1518 (1.8%) had PGDM. Compared to NG patients, overall cesarean rates were higher in patients with GDM (40.3% vs. 29.7%; aOR 1.25, 95%CI 1.18-1.31) and PGDM (60.0% vs. 29.7%; aOR 2.53, 95%CI 2.04-3.13). This finding remained true when the cohort was restricted to term, singleton, vertex laboring patients without a prior cesarean; compared to NG patients, the cesarean rate was higher in patients with GDM (17.4% vs. 12.2%, aOR 1.37, 95%CI 1.29-1.45) and PGDM (26.0% vs. 12.2%, aOR 2.55, 95%CI 2.00-3.25). The cesarean rate for fetal indications was similar in the GDM (5.7%) and NG (4.4%) groups, while those patients with PGDM had a significantly higher rate (10.4%; aOR 2.01, 95%CI 1.43-2.83). Similarly, the rate of cesarean for labor dystocia in patients with PGDM was significantly higher than in NG patients (16.9% vs. 7.0%, and aOR 2.28, 95%CI 1.66-3.13) while patients with GDM had an intermediate rate (10.6% vs. 7.0%, aOR 1.49, 95%CI 1.40-1.57). CONCLUSIONS The CD rate is significantly higher in pregnancies complicated by diabetes, particularly pregestational, compared to NG pregnancies. Despite controlling for maternal factors and birth weight, pregnancies complicated by diabetes are more likely to undergo an unplanned intrapartum cesarean secondary to labor dystocia than their NG counterparts, but only pregnancies complicated by PGDM have an increased risk of cesarean for fetal indications. More research is needed to understand whether this higher cesarean rate is due to factors intrinsic to diabetes in laboring patients or is due to a difference in the way clinicians manage diabetics in labor.

Abstract
OBJECTIVE Among risk factors for SB, maternal endocrine diseases (ED), such as thyroids dysfunction and gestational diabetes mellitus (GDM), are the most frequent. This study aimed to investigate the rate of ED in a population of SB cases collected prospectively, and the relationship between these and causes of death. METHODS This is an area-based, prospective cohort study conducted in Emilia-Romagna, Italy between January 2014 and December 2020. Data included all cases of SB (>22 weeks). RESULTS From 2014 to 2020, 766 SB occurred out of a total of 232.506 births (SB rate:0.3/1000). The ED were present in 197/766 cases of SB (25.7%), respectively, 104 thyroid disease (52.8%), 74 GDM (37.5%), and 19 cases of concomitant GDM and thyroid disease (9.6%). Women who had SB associated with ED presented significantly higher mean maternal age (p < 0.001), BMI (p < 0.001), obesity (p < 0.001) and lower smoking habit (p = 0.02) respect with control group. Neonatal and placental weight of stillborn women with ED was significantly higher (p < 0.001) in respect to stillborn of the control group. Women with ED as associated condition (ReCODE classification), present significantly higher cases of SB caused by placenta pathologies (p = 0.009) namely abruptio placentae (p = 0.001) respect than control group. CONCLUSIONS ED was more frequent in older and obese women experiencing SB. The main cause of death was abruptio placentae. This information can be helpful when counseling mothers with ED and planning antenatal management to prevent SB.

Is Misoprostol Vaginal Insert Safe for the Induction of Labor in High-Risk Pregnancy Obese Women? Healthcare (Basel) 2021; 9:healthcare9040464. [PMID: 33919898 PMCID: PMC8070889 DOI: 10.3390/healthcare9040464] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 04/07/2021] [Accepted: 04/12/2021] [Indexed: 11/21/2022] Open
Abstract
Induction of labor (IOL) is an event that occurs in up to 25% of pregnancies. In Europe, the misoprostol vaginal insert (MVI—Misodel®) was approved for labor induction in 2013. Studies on the outcomes and safety of IOL in obese pregnant women are scarce; no data are available on MVI IOL in high-risk pregnancy obese women (HRPO—late-term, hypertension, diabetes). As the obesity rates are growing steadily in pregnant women, we aimed to evaluate the failure rate for induction and the safety of a 200 μg MVI in obese (body mass index (BMI) >30 kg/m2) HRPO compared to that for obese non-high-risk pregnancies (non-HRPO). For this purpose, we conducted a cross-sectional study in “Filantropia” Clinical Hospital, Bucharest, Romania, from June 2017—the date of the initiation of the MVI IOL protocol in our clinic—to September 2019. The primary outcomes were the failure rate, measured by cesarean section (CS) ratio, and secondarily, the safety profile of MVI, analyzed by one-way ANOVA. Out of a total of 11,096 registered live births, IOL was performed on 206 obese patients. Of these, 74 obese pregnant women had their labor induced with MVI (HRPO, n = 57, and non-HRPO, n = 17). The average maternal age was 29.9 ± 4.8 years (19–44 years). Across the groups, the rate of CS was 29.8% (n = 17) in the HRPO group compared to 23.5% (n = 4) in the non-HRPO group (p = non significant). In the vaginally birth subgroups, the median time from drug administration to delivery was shorter in the HRPO group compared to the non-HRPO group (16.9 ± 6.0 h 95% confidence interval (CI) 15.0–18.8 vs. 19.4 ± 9.2 h 95% CI 13.8–25.0, p = 0.03). No significant differences were found regarding the maternal outcomes among the studied groups; in terms of perinatal outcomes of safety, 5.4% (n = 4) of the cases of vaginal delivery for HRPO were associated with neonatal intensive care unit (NICU) admissions. The MVI seems to be an efficient labor induction agent in high-risk pregnancy obese women with good maternal outcomes and low perinatologic complications.

Abstract
In just 50 years the prevalence of autism spectrum disorder has vaulted from extremely rare to common in every community. During this time, a large body of scientific literature has been amassed regarding what environmental, genetic, maternal, or obstetric factors may be at work. The hypothesis presented here identifies two developments in today's childbirth experience that, in combination, may provide the key: 1) a significant increase in the mean duration of labor and 2) the adoption of continuous electronic fetal monitoring utilizing Doppler ultrasound as the standard of care even in low-risk pregnancies. Together, these two factors have created an unprecedented fetal environment that has the potential to affect neuronal migration and cause non-inherited genetic disruptions. This paper will briefly describe the nature and history of contributing factors, why there may be a link between evolving maternal characteristics, obstetric trends and the increase in autism, as well as the means by which the hypothesis can be tested.

Abstract
BACKGROUND Misoprostol is a common agent that is used to ripen the cervix and induce labor, yet there is no clear evidence of the optimal number of doses needed to achieve a higher rate of vaginal delivery. OBJECTIVE Our primary objective was to compare the rate of vaginal delivery within 24 hours between a 1-dose and a multiple-dose regimen of misoprostol for the induction of labor. STUDY DESIGN A randomized controlled trial was conducted from March 2016 to March 2017 that compared a single dose to up to 4 doses of misoprostol. Randomization was stratified by parity. Women with a singleton pregnancy ≥37 weeks gestation with intact membranes who had been admitted for labor induction with a Bishop score ≤6 were included. Our primary outcome was the rate of vaginal delivery within 24 hours. Secondary outcomes included time to vaginal delivery, cesarean delivery rate, and maternal and neonatal morbidity. Based on a power of 80%, an alpha of .05, and the assumption that 50% of women in the multiple-misoprostol group would deliver vaginally in 24 hours, a sample size of 220 patients was needed to detect a 20% increase in vaginal delivery rate within 24 hours in the 1-misoprostol group. Continuous variables were compared with the use of the Mann-Whitney test. Categoric variables were compared with the use of the Fisher's exact test. Probability values <.05 were considered statistically significant. RESULTS Two hundred fifty women were assigned randomly. Demographics and clinical characteristics were similar between groups. In the univariate analysis, there was no difference in the rate of vaginal delivery within 24 hours between the 1-misoprostol group and the multiple-dose group (41.7% vs 44.7%, respectively; P=.698) or time to vaginal delivery (1187 min vs 1321 min, respectively; P=.202). The 1-misoprostol group had a greater cesarean delivery rate (35.8% vs 22.8%; P=.034). In a Poisson regression that controlled for Bishop score before the initiation of oxytocin, parity, gestational age, body mass index, estimated fetal weight, artificial rupture of membrane at <6 cm, and Foley balloon placement, the treatment group was no longer associated with cesarean delivery rate. Instead, a Bishop score of <4 before the initiation of oxytocin and nulliparity were associated significantly with cesarean delivery rate. CONCLUSION In this first randomized controlled trial in the literature to compare a single with a multiple dosing of misoprostol, we found that the 1-dose regimen is an acceptable alternative for the induction for labor, especially for multiparous women and for patients with a Bishop score >4 after the first dose.

Abstract
OBJECTIVE To investigate the effects of gestational diabetes mellitus (GDM) on time to delivery and perinatal outcomes in full-term pregnancies underwent dinoprostone-induced labor. METHODS GDM patients that underwent labor induction with dinoprostone vaginal inserts were retrospectively recruited. Full-term pregnancies with normal glucose tolerance (NGT) that underwent labor induction at the same period were recruited as control. Time to delivery and perinatal outcomes were compared between the two groups. RESULTS A total of 1555 pregnancies with 226 GDM and 1329 NGT were recruited. GDM pregnancies had older ages, lower gestational age, higher body mass index (BMI) and abortion history, and more multigravida than NGT pregnancies (P< 0.05). Univariate analysis showed no significant difference in time to delivery and delivery rates between the two groups. However, after adjusted in a multivariate analysis model, the delivery rates of GDM women delivered within 12, 24, 36 or 48 h and those vaginally delivered within 12 or 36 h were significantly lower than those in the NGT group (P< 0.05). Perinatal outcomes were clinically similar between the two groups. CONCLUSION GDM did not affect the time to delivery, cesarean delivery and other perinatal outcomes in Chinese women underwent dinoprostone-induced labor. However, it may be associated with the lower rates of delivery within different time intervals.
