Summary: Induction of labor is a common procedure in modern obstetrics and its frequency is expected to increase. The study found that the use of Misoprostol for labor induction may lead to more cesarean sections and nonreassuring fetal heart rate patterns. On the other hand, using Dinoprostone or Foley catheter for induction may prolong labor time but with a lower risk of nonreassuring fetal heart rate patterns.

Summary: This study compared the effectiveness and safety of Dinoprostone vaginal insert and double-balloon catheter for labor induction. The results showed that Dinoprostone group had a higher rate of vaginal delivery within 48 hours, lower cesarean section rate, and lower risk of chorioamnionitis compared to the double-balloon catheter group.

Summary: The study aimed to validate a mathematical model for predicting mean time to delivery (TTD) following cervical ripening with dinoprostone vaginal insert (DVI), but found that the model was not effective in predicting TTD or reducing the number of nocturnal deliveries.

Summary: The study found no significant difference in cesarean delivery rates between outpatient and inpatient cervical ripening, but the comparison results for potential harms were not clear.

Summary: This study indicates that both pharmacological and mechanical methods can be safely and efficiently used for cervical ripening in women with decreased fetal movements at term. Nulliparous women may experience longer labor with repeat prostaglandin E2 use compared to the cervical ripening balloon group, but maternal or fetal safety is not compromised.

Summary: This study compared the effects of Foley catheter and controlled-release dinoprostone vaginal insert on the induction-to-delivery interval and maternal satisfaction in women with one previous cesarean delivery. The results showed that controlled-release dinoprostone vaginal insert shortened the induction-to-delivery interval, but did not significantly increase maternal satisfaction.

Summary: This study aimed to develop and validate a predictive model to estimate the risk of obstetrical anal sphincter injuries in women undergoing vaginal birth after cesarean delivery. The model identified several risk factors, such as forceps and vacuum assistance, and provided a validated estimate of the probability of obstetrical anal sphincter injuries. Internal and external validation showed appropriate discrimination and calibration of the model, which can be used to counsel patients regarding the risks of trial of labor after cesarean delivery.

Summary: This study investigated the risk factors associated with a change in fetal presentation from cephalic to noncephalic after mechanical cervical ripening. The study found that nulliparity and multiple gestation increased the likelihood of cesarean delivery for an intrapartum presentation change.

Summary: By comparing ultrasonographic and non-ultrasonographic factors from five hospitals in China, we developed and validated a prediction model for vaginal birth after cesarean delivery (VBAC). The model includes 8 validated factors and can accurately predict the success rate of trial of labor after cesarean (TOLAC).

Summary: This study successfully developed an accurate tool to predict the probability of vaginal birth after cesarean delivery early in pregnancy without including race or ethnicity variables. Factors such as maternal age, prepregnancy weight, indication for previous cesarean delivery, obstetrical history, and chronic hypertension were found to be significantly associated with vaginal birth after cesarean delivery in the prediction model. The model demonstrated good calibration and had a similar area under the receiver operating characteristic curve compared to the previous model that included race and ethnicity.

Summary: A prospective observational study was conducted on 204 women who underwent induction of labour using a vaginal prostaglandin slow-release delivery system. Three predictive models were created to predict effective cervical ripening, and all three models showed good predictive capabilities. Model C, which included variables such as gestational age, premature rupture of membranes, body mass index, estimated fetal weight, and Bishop score, was identified as the model of choice with an area under the ROC curve of 0.76. This predictive model can be a useful tool in clinical decision-making regarding induction of labour.

Summary: This study compares the safety and efficacy of different methods of induction of labor in twin gestations and their effect on maternal and neonatal outcomes. The study found that patients with a twin gestation who underwent induction of labor were more likely to have a cesarean delivery compared to those who went into labor spontaneously, but there were no significant differences in the maternal or neonatal outcomes. Moreover, the method of induction of labor did not affect the success rates or the rates of adverse maternal or neonatal outcomes.

Summary: Immediate oxytocin and early amniotomy after Foley catheter cervical ripening shortened the intervention-to-delivery interval in nulliparous women, but did not significantly reduce the cesarean delivery rate.

Summary: The study aimed to validate the MFMU's VBAC calculator in an Israeli cohort and discover other variables associated with VBAC, resulting in an improved VBAC calculator. The results showed that the MFMU's calculator underperformed compared to the original publication, but an improved model including additional variables demonstrated better prediction performance.

Summary: This study investigated the predictive value of obstetric findings in using PGE2 vaginal inserts for cervical ripening, and compared the optimal method of cervical ripening between PGE2 vaginal inserts and/or cervical dilators. The results showed that PGE2 vaginal inserts were effective when the uterine cervical os was at least 2 cm in diameter. In cases of extremely immature cervical ripening, it was feasible to use PGE2 vaginal inserts before mechanical cervical dilatation.
