Pregnancies in Women with a Previous Complete Uterine Rupture.

Objective: To study the outcomes of new pregnancies after a previous complete uterine rupture.

Design: Descriptive study based on population data from the Medical Birth Registry of Norway, the Patient Administration System, and the medical records. .

Depressive symptoms and experiences of birthing mothers during COVID-19 pandemic.

Background: It is unclear how the COVID-19 pandemic has affected postnatal women in Norway. We therefore wanted to investigate their depressive symptoms and birthing experiences during the pandemic.

Material And Method: In April 2021, a total of 3 642 postnatal women participated in an online survey.

COVID-19 in pregnancy-characteristics and outcomes of pregnant women admitted to hospital because of SARS-CoV-2 infection in the Nordic countries.

Introduction: Population-based studies about the consequences of SARS-CoV-2 infection (COVID-19) in pregnancy are few and have limited generalizability to the Nordic population and healthcare systems.

Material And Methods: This study examines pregnant women with COVID-19 in the five Nordic countries. Pregnant women were included if they were admitted to hospital between 1 March and 30 June 2020 and had a positive SARS-CoV-2 PCR test ≤14 days prior to admission.

Prelabour uterine rupture: characteristics and outcomes.

Objective: To describe the characteristics and outcomes of prelabour uterine ruptures.

Design: Descriptive study based on population data from the Medical Birth Registry of Norway, the Patient Administration System and medical records.

Sample: Maternities with uterine rupture before start of labour in Norway during the period 1967-2008 (8 complete ruptures among 2 334 712 women with unscarred uteri, and 22 complete and 45 partial ruptures among 121 085 women with scarred uteri).

Maternal outcome after complete uterine rupture.

Introduction: Complete uterine rupture, a rare peripartum complication, is often associated with a catastrophic outcome for both mother and child. However, few studies have investigated large datasets to evaluate maternal outcomes after complete ruptures, particularly in unscarred uteri. This paucity of studies is partly due to the rarity of both the event and the serious outcomes, such as peripartum hysterectomy and maternal death.

Infant outcome after complete uterine rupture.

Background: Complete uterine rupture is a rare peripartum complication often associated with a catastrophic outcome for both mother and child. However, little has been written based on large data sets about maternal and infant outcome after complete ruptures. This is partly due to the rarity of the event and the serious maternal and infant outcome; it is also partly due to the use of international diagnostic codes that do not differentiate between the less catastrophic partial rupture and more catastrophic complete uterine rupture.

Risk factors for severe postpartum hemorrhage: a case-control study.

Background: In high-income countries, the incidence of severe postpartum hemorrhage (PPH) has increased. This has important public health relevance because severe PPH is a leading cause of major maternal morbidity. However, few studies have identified risk factors for severe PPH within a contemporary obstetric cohort.

Risk factors for complete uterine rupture.

Background: Complete uterine rupture is a rare peripartum complication associated with a catastrophic outcome. Because of its rarity, knowledge about its risk factors is not very accurate. Most previous studies were small and over a limited time interval.

Uterine rupture: trends over 40 years.

Objective: To follow trends of uterine rupture over a period of 40 years in Norway.

Design: Population-based study using data from the Medical Birth Registry, the Patient Administration System, and medical records.

Setting: Norway.

Validation study of uterine rupture registration in the Medical Birth Registry of Norway.

Objective: To validate uterine rupture registration in the Medical Birth Registry of Norway (MBRN) between 1999 and 2008, and to identify rupture type and causes of incorrect or missed registration during 1967-2008.

Design: Population-based study.

Population: The validation sample was 392,958 maternities from 21 maternity units registered in MBRN and local Patient Administration Systems in 1999-2008.

Uterine rupture after previous caesarean section.

Objective: To determine the risk factors, percentage and maternal and perinatal complications of uterine rupture after previous caesarean section.

Design: Population-based registry study.

Population: Mothers with births > or =28 weeks of gestation after previous caesarean section (n = 18 794), registered in the Medical Birth Registry of Norway, from 1 January 1999 to 30 June 2005.

Effects of onset of labor and mode of delivery on severe postpartum hemorrhage.

Objective: Our purpose was to study the impact of labor onset and delivery mode on the risk of severe postpartum hemorrhage.

Study Design: This was a population-based study of 307,415 mothers who were registered in the Medical Birth Registry of Norway from 1999-2004.

Results: Severe postpartum hemorrhage occurred in 1.

Prevalence and risk factors of severe obstetric haemorrhage.

Objective: To determine the prevalence, causes, risk factors and acute maternal complications of severe obstetric haemorrhage.

Design: Population-based registry study.

Population: All women giving birth (307,415) from 1 January 1999 to 30 April 2004 registered in the Medical Birth Registry of Norway.
