Postnatal betamethasone treatment in extremely preterm infants and risk of neurodevelopmental impairment: a cohort study.

Objective: To evaluate if postnatal treatment with betamethasone in extremely preterm infants was associated with neurodevelopmental impairment (NDI) at 6.5 years of age.

Design: Prospective cohort study.

Hospital obstetric volume and maternal outcomes: Does hospital size matter?

Introduction: In recent decades, centralization of health care has resulted in a number of obstetric unit closures. While studies support better infant outcomes in larger facilities, few have investigated maternal outcomes. We investigated obstetric unit closures over time and whether obstetric volume is associated with onset of labor, postpartum hemorrhage (PPH) and obstetric anal sphincter injury (OASIS).

Midwifery Continuity of Care During Pregnancy, Birth, and the Postpartum Period: A Matched Cohort Study.

Objective: To compare pregnancy outcomes in a midwifery continuity of care (MCoC) model to standard midwifery care in Sweden.

Design: Matched cohort study.

Setting: Public healthcare during pregnancy and childbirth, Stockholm, Sweden.

Risk of postpartum hemorrhage with increasing first stage labor duration.

With increasing rates of postpartum hemorrhage (PPH) in high-income countries, an important clinical concern is the impact of labor duration on the risk of PPH. This study examined the relationship between increasing active first stage labor duration and PPH and explored the role of second stage labor duration and cesarean delivery (CD) in this association. Including 77,690 nulliparous women with spontaneous labor onset, first stage labor duration was defined as the time from 5 cm to 10 cm, second stage duration from 10 cm dilation to birth and PPH as estimated blood loss > 1000 ml.
