Background: Induction of labour has remained one of the most valuable interventions in obstetric practice. Over the years, the proportion of women undergoing induction of labour (IOL) has been on a steady increase. The significance to obstetrics practice as well as its maternal and perinatal outcomes are sacrosanct, hence the need for its periodic review.
Objective: To determine the obstetric outcomes of induction of labour.
Methods: A five-year retrospective study of all cases of induction of labour at the maternity unit of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria between January 1st 2017 and 31st December 2021. The labour ward's records were assessed to determine the total number of women who had induction of labour during the study period. Women whose case files could be not retrieved were excluded. The folder numbers of the patients were extracted and their case files retrieved from the medical records department of the hospital. The primary outcomes measures were the indications and the methods of induction of labour, while the secondary outcome measures were the mode of delivery, cause of failed induction, and the perinatal outcome. Data were obtained using proformas and analysed using statistical packages for social sciences (SPSS) version 26.0 IBM corporation.
Result: A total of 3,638 deliveries were taken during the period under review and 168 patients had induction of labour giving an overall prevalence of 4.6% (46/1000 deliveries). Induction of labour was successful in 71.2% of cases. Misoprostol was used in 90.4% of cases as an induction agent. The commonest indication for induction of labour was postdate pregnancy (53.8%). Failed induction was due to fetal distress, poor progress of labour from cephalopelvic disproportion/malposition and failed cervical ripening. In about 72% of deliveries, there was good perinatal outcome, 10.3% of babies had moderate to severe asphyxia while 1.3% had neonatal death.
Conclusion: Induction of labour is a safe and beneficial procedure in obstetrics. However, it can be associated with adverse obstetric outcomes.

Maternal and perinatal outcomes after implementation of a more active management in late- and postterm pregnancies in Sweden: A population-based cohort study.

Background: The risk of perinatal death and severe neonatal morbidity increases gradually after 41 weeks of pregnancy. We evaluated maternal and perinatal outcomes after a national shift from expectancy and induction at 42+0 weeks to a more active management of late-term pregnancies in Sweden offering induction from 41+0 weeks or an individual plan aiming at birth or active labour no later than 42+0 weeks.
Methods And Findings: Women with a singleton pregnancy lasting 41+0 weeks or more with a fetus in cephalic presentation (N = 150,370) were included in a nationwide, register-based cohort study.

Background: Induction of labour (IOL) is a common obstetric intervention in the UK, affecting up to 33% of deliveries. IOL aims to achieve a vaginal delivery prior to spontaneous onset of labour to prevent harm from ongoing pregnancy complications and is known to prevent stillbirths and reduce neonatal intensive care unit admissions. However, IOL doesn't come without risk and overall, 20% of mothers having an induction will still require a caesarean section birth and in primiparous mothers this rate is even higher.

In the management of pregnancy, ritodrine has been used to prevent preterm birth, and magnesium sulfate (MgSO) has been used to prevent preterm labor and preeclampsia. Neonates born to mothers receiving these medications occasionally show an increase in serum potassium concentration. Recently, an elevated risk of neonatal hyperkalemia has been reported, particularly when ritodrine and MgSO are co-administered; however, the underlying mechanisms remain unclear.

Background: Most studies on respectful maternity care (RMC) and mistreatment of women have focused on intrapartum care with limited information on how women are treated during induction of labor (IOL), pre-labor phase of the maternity care continuum. Emerging multi-country evidence indicates that nearly 30% of women who undergo IOL do not consent to the procedure and constitutes a violation of their rights to optimal maternal health. This study explored women's lived experiences of respectful care and mistreatment during IOL in a tertiary setting in Ghana.

Background: Crohn's disease (CD) is a refractory inflammatory bowel disease with an unclear etiology. CircularRNA (circRNA) has been highlighted as a novel class of functional noncoding RNAs associated with the pathogenesis of various diseases. However, the functions of circRNA in CD remain unclear.
