Cohort profile: The PreEclampsia, Angiogenesis, Cardiac dysfunction and Hypertension (PEACH) Study.

Background: Hypertensive disorders of pregnancy (HDP) remain a leading cause of maternal morbidity and mortality worldwide, with implications for maternal and neonatal well-being in the short term and for long-term maternal cardiovascular health. Although the mechanisms behind HDP remain incompletely understood, evidence suggests that preeclampsia in particular is a syndrome with more than one distinct subtype.

Objectives: The PEACH (PreEclampsia, Angiogenesis, Cardiac dysfunction, Hypertension) Study was established to identify new HDP subtyping systems reflecting aetiology and prognosis and to find markers of later cardiovascular disease risk associated with preeclampsia.

Anal incontinence after two vaginal deliveries without obstetric anal sphincter rupture.

Purpose: To evaluate prevalence and risk factors for long-term anal incontinence in women with two prior vaginal deliveries without obstetric anal sphincter injury (OASIS) and to assess the impact of anal incontinence-related symptoms on quality of life.

Methods: This is a nation-wide cross-sectional survey study. One thousand women who had a first vaginal delivery and a subsequent delivery, both without OASIS, between 1997 and 2008 in Denmark were identified in the Danish Medical Birth Registry.

Episiotomy in vacuum-assisted delivery affects the risk of obstetric anal sphincter injury: a systematic review and meta-analysis.

The risk of obstetric anal sphincter injury (OASIS) is increased in vacuum-assisted delivery. However, it remains unclear whether episiotomy may protect against OASIS in this type of delivery. The objective of this study was to assess whether mediolateral or lateral episiotomy affects the risk of OASIS in vacuum-assisted delivery among primiparous women.
