Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

The Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Optimal timing for induction of labor in normotensive women: A retrospective cohort study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 365-371, April 2025.
Abstract Objective Labor induction is offered to reduce the risk of stillbirth at late term (41+0 to 41+6) but earlier induction in normotensive singleton pregnancies is supported by weak evidence. The aim of the present study was to investigate the optimal timing for induction in normotensive women.

The rising tide: Trends in induction of labor at term over a 5‐year period at a single centre

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 383-390, April 2025.
Abstract Objective Induction of labor (IOL) is a controversial topic in contemporary obstetric practice, with some suggesting that the increase in elective induction (eIOL) as a potential contributor to increasing cesarean delivery (CD) rates. The objectives of this single‐center study were to examine the rates of IOL, trends in indications for IOL ...

The association between epidural analgesia and perineal injury in primiparous women: A propensity score‐matched cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To determine the association between epidural analgesia and perineal injury, including obstetric anal sphincter injury (OASI), in primiparous women. Methods We conducted a retrospective cohort study of primiparous women with singleton, term, vertex, and vaginal deliveries between 2012 and 2024 at a tertiary medical center.

Adverse perinatal outcomes associated with macrosomia in nulliparous women: A multicenter cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Our study aimed to evaluate the combined risk of macrosomia and nulliparity. We investigated whether macrosomia is independently associated with an increased rate of intrapartum cesarean delivery (CD) and adverse maternal and neonatal outcomes among nulliparous women delivering at term.

Maternal morbidity following a trial of labor after cesarean birth: A scoping review of operative vaginal birth compared with cesarean birth in the second stage of labor

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Increased use of operative vaginal birth (OVB; forceps and vacuum) has been proposed as a strategy to avoid cesarean birth (CB) among individuals who elect a trial of labour after CB (TOLAC). The relative maternal safety of OVB and CB in individuals with a TOLAC is poorly understood. Objective To summarize the available evidence and
