Abstract
PURPOSE To compare the effectiveness of vaginal misoprostol for second-trimester termination between pregnancies with a dead fetus in utero and those with a live fetus and to identify factors associated with the success rate. METHODS Singleton pregnancies with live fetuses and dead fetuses, between 14 and 28 weeks of gestation, with an unfavorable cervix, were recruited to have pregnancy termination with intravaginal misoprostol 400 mcg every 6 h. RESULTS Misoprostol was highly effective for termination, with a low failure rate of 6.3%. The effectiveness was significantly higher in pregnancies with a dead fetus (log-rank test; p: 0.008), with a median delivery time of 11.2 vs. 16.7 h. Fetal viability, fetal weight or gestational age, and an initial Bishop score were significantly associated with the total amount of misoprostol dosage used for induction. Fetal viability and gestational age/fetal weight were still independent factors after adjustment for other co-factors on multivariate analysis. CONCLUSION Vaginal misoprostol is highly effective for second-trimester termination, with significantly higher effectiveness in pregnancies with a dead fetus. Also, the effectiveness is significantly associated with birth weight/gestational age, and initial Bishop score.

Abstract
OBJECTIVE To evaluate vaginal delivery in obese women who underwent cervical ripening at term using a dinoprostone vaginal insert or a cervical ripening balloon (CRB), and to assess maternal and neonatal morbidity according to the method. METHODS A prospective cohort study including obese women with a live singleton fetus in cephalic presentation who required cervical ripening at term (≥37 weeks) for maternal and/or fetal disease using a dinoprostone vaginal insert or a CRB. The primary outcome was vaginal delivery. Secondary outcomes were a favorable cervix (Bishop score >6) after 24 h, the time from device insertion to delivery, and composite maternal and neonatal morbidity. RESULTS In total, 135 consecutive women were analyzed (107 CRB, 79.3%; 28 dinoprostone vaginal insert, 20.7%). Vaginal delivery (86 [80.4%] after CRB vs 19 [67.9%] after dinoprostone vaginal insert; P = 0.248), favorable cervix within 24 h after device placement (52 [48.6%] vs 17 [60.7%]; P = 0.264), and maternal morbidity (12 [11.2%] vs 4 [14.3%]; P = 0.646) were similar between the groups. The time from device insertion to delivery also did not differ between the groups. Neonatal morbidity was significantly higher after the dinoprostone vaginal insert (11 [39.3%] vs 20 [18.7%]; P = 0.030). Cervical ripening using the dinoprostone vaginal insert, compared with the CRB, was significantly associated with neonatal morbidity (adjusted odds ratio 4.00, 95% confidence interval 1.34-12.5), but not with maternal morbidity (adjusted odds ratio 1.23, 95% confidence interval 0.30-4.38). CONCLUSIONS Vaginal delivery, a favorable cervix after 24 h, the time from device insertion to delivery, and maternal morbidity did not significantly differ between the CRB and the dinoprostone vaginal insert for cervical ripening in obese women at term. Nevertheless, neonatal morbidity was significantly associated with the dinoprostone vaginal insert, compared with the CRB, among obese women who required cervical ripening at term.

Abstract
INTRODUCTION Obesity is an increasing public health concern worldwide and can lead to more complications in pregnancy and childbirth. Women with obesity more often require induction of labor for various indications. The aim of this study is to assess which method of induction of labor is safest and most effective in women with obesity. MATERIAL AND METHODS This is a secondary analysis of two randomized controlled trials about induction of labor. Women with a term singleton pregnancy in cephalic presentation, an unfavorable cervix, intact membranes and without a previous cesarean section were randomly allocated to cervical priming with a Foley catheter or vaginal prostaglandin-E2-gel (PROBAAT-I) or a Foley catheter or oral misoprostol (PROBAAT-II). The inclusion and exclusion criteria for the studies were identical. Induction methods were compared in women with obesity (body mass index ≥30.0). Main outcomes were cesarean section and postpartum hemorrhage (blood loss >1000 mL). RESULTS A total of 2664 women, were included in the trials, 517 of whom were obese: 254 women with obesity received a Foley catheter, 176 oral misoprostol and 87 prostaglandin E2 (PGE2). A cesarean section was performed in 29.1% of women allocated to Foley vs 22.2% in the misoprostol and 23.0% in the PGE2 groups. Comparisons between groups revealed no statistically significant differences: the relative risk [RR] was 1.31 (95% confidence interval [CI] 0.94-1.84) in the Foley vs misoprostol group and 1.27 (95% CI 0.83-1.95) in the Foley vs PGE2 group. The rates of postpartum hemorrhage were comparable (10.6%, 11.4% and 6.9%, respectively; P = 0.512). In women with obesity, more often a switch to another method occurred in the Foley group, (20.1% vs 6.3% in misoprostol vs 1.1% in the PGE2 group; P < 0.001). The risk of a failed Foley placement was higher in women with obesity than in women without obesity (8.3% vs 3.2%; adjusted odds ratio 3.12, 95% CI 1.65-5.90). CONCLUSIONS In women with obesity we found a nonsignificant trend towards an increased rate of cesarean sections in the group induced with a Foley catheter compared to oral misoprostol; however, the study lacked power for this subgroup analysis. The finding of a higher risk of failed placement of a Foley catheter in women with obesity can be used in shared decision making.

Abstract
OBJECTIVE To compare cesarean rates and maternal and neonatal morbidity according to the cervical ripening method used among obese pregnant women requiring induction of labor at or after 41 weeks of gestation. DESIGN A secondary analysis of two multicenter randomized controlled trials conducted in French maternity units between 2015 and 2018. PARTICIPANTS 336 women with a body mass index ≥30 kg/m2, a pregnancy ≥41 weeks, and an induction of labor requiring cervical ripening. INTERVENTIONS Cervical ripening with a PGE2 dinoprostone pessary (Propess®), or low-dose vaginal PGE1 (misoprostol) or a double-balloon catheter. MEASUREMENTS AND FINDINGS The rates of cesarean delivery did not differ significantly according to the cervical ripening method (PGE2 pessary vs PGE1, RR: 1.18, 95% CI: 0.80-1.75; PGE2 pessary vs double balloon catheter: RR, 0.88, 95% CI: 0.60-1.29), p = 0.52; double balloon catheter vs PGE1, RR: 1.34, 95% CI: 0.77-2.32, p = 0.29). More oxytocin was required for women from the double-balloon group compared to those from both the PGE1 and PGE2 pessary groups (respectively, RR: 1.31, 95% CI: 1.08-1.58, p = 0.005; RR: 1.17, 95% CI: 1.03-1.32, p = 0.01). The risk of perineal tears or episiotomy was significantly lower for women induced with the PGE2 pessary than with PGE1 (0.85; 95% CI: 0.74-0.99), p = 0.03). KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE No cervical ripening method was associated with a lower cesarean rate in obese women who required cervical ripening from 41 weeks. Further trials are required among obese women to determine the cervical ripening method most efficacious for reducing the cesarean rate.

Abstract
Data regarding the preferred induction method in women with obesity is scarce. The current study was aimed at comparing pharmacological and mechanical induction in this population. This prospective randomized controlled trial was conducted between 2016−2020, in nulliparas with a pre-pregnancy body mass index >30. Inclusion criteria were singleton-term pregnancies, bishop score < 5, and indication for induction. Patients were randomized to induction by a cervical ripening balloon (CRB) or a 10 mg vaginal dinoprostone insert. The primary outcome was delivery rate within 24 h. Secondary outcomes included time to delivery, cesarean section rate, maternal and neonatal outcomes, satisfaction, and anxiety. The study population comprised of 83 women in the CRB group and 81 in the dinoprostone group. There was a significant difference in delivery rates within 24 h and time to delivery between the dinoprostone and CRB groups (45% vs. 71%, p = 0.017 and 49.3 ± 6.8 h vs. 23.5 ± 5.9 h, p = 0.003, respectively). There were no differences in cesarean delivery rates or maternal and neonatal outcomes, though CRB induction was associated with a significantly lower rate of tachysystole. Induction with CRB was accompanied by higher satisfaction and lower anxiety. In summary, CRB induction is associated with shorter time to delivery, higher satisfaction, and lower anxiety compared to PGE2 in women with obesity, without compromising maternal or neonatal outcomes.

Abstract
People with obesity may require induction of labour (IoL) due to a higher incidence of pre-existing comorbidities and pregnancy complications, as well as to prevent post-term pregnancies and late-term stillbirths. IoL at 39-40 weeks is associated with fewer caesarean births and lower morbidity for the pregnant person and neonate when compared with expectant management. Ensuring the success and safety of IoL in people with obesity requires adherence to evidence-based protocols for the management of labour induction and augmentation. Cervical ripening as well as the latent and active phases of labour in people with obesity may be considerably prolonged, requiring higher cumulative doses of oxytocin. This should be guided by intrauterine pressure catheters and early provision of neuraxial analgesia, where possible. There is insufficient evidence to recommend one method of IoL over another. The need for higher doses of prostaglandins and concurrent agents for cervical ripening should be studied in prospective studies.
