Early labour experience and labour characteristics after introduction of an electronic early labour educational intervention.

Objective: The study's aim was to compare first-time mothers' experience of early labour and subsequent labour characteristics before and after introducing an online early labour educational intervention. This article also reports on further testing of the underlying structure of the of the Early Labour Experience Questionnaire (ELEQ) in a Norwegian setting.

Methods: Pre- and post-intervention cohorts were recruited.

Nucleation status of Day 2 pre-implantation embryos, acquired by time-lapse imaging during IVF, is associated with live birth.

The primary purpose of this time-lapse data analysis was to identify the association between the nucleation status of a Day 2 preimplantation embryo and live births following in vitro fertilization (IVF). The retrospective data analysis was based on 2769 transferred embryos from 1966 treatment cycles and utilised only Known Implantation Data (KID) for live births. Nucleation errors (NE) such as micronucleation, binucleation, multinucleation and minor error groups, were annotated in the time-lapse images which were taken every 15 minutes for a minimum of 44 hours post insemination.

Development of and Experiences With an Informational Website on Early Labor: Qualitative User Involvement Study.

Background: The period of regular contractions before 4 cm of cervical dilatation is often referred to as the latent phase or early labor. Women find it challenging to prepare for and cope with this phase of labor, and easily accessed web-based information from reliable sources may be useful in this preparation.

Objective: The aim of this study is to describe the development of a Norwegian website, Latens.

A qualitative study of Norwegian first-time mothers' information needs in pre-admission early labour.

Objective: To explore women's experience with information, and their information needs in pre-admission early labour.

Design: A qualitative study with an exploratory and descriptive approach.

Setting: Five focus group interviews with women attending post-natal care at five different well-baby clinics in South-Eastern Norway in 2019.

Time-lapse imaging derived morphokinetic variables reveal association with implantation and live birth following in vitro fertilization: A retrospective study using data from transferred human embryos.

The purpose of this retrospective time-lapse data analysis from transferred preimplantation human embryos was to identify early morphokinetic cleavage variables that are related to implantation and live birth following in vitro fertilization (IVF). All embryos were monitored from fertilization check until embryo transfer for a minimum of 44 hours. The study was designed to assess the association between day 2 embryo morphokinetic variables with implantation and live birth based on Known Implantation Data (KID).

Validation of Assisted Reproductive Technology in the Medical Birth Registry of Norway Versus the Norwegian Prescription Database.

Background: Increasing attention has been given to the long-term effects of assisted reproductive technology (ART). This study assessed the validity and completeness of ART as registered in the Medical Birth Registry of Norway (MBRN) using drug prescription data from the Norwegian Prescription Database (NorPD) as reference.

Methods: In this nationwide registry validation study, we included all pregnancies recorded in the MBRN between 2005 and 2017.

Cancer risk in mother and child after fertility treatment.

Bakgrunn: I Norge fødes nå om lag 2 500 barn årlig etter fertilitetsbehandling. Hvorvidt behandlingen er forbundet med økt kreftrisiko, er fremdeles usikkert.

Kunnskapsgrunnlag: Oversikten inkluderer kohortstudier om kreftrisiko hos kvinner behandlet med fertilitetsbehandling og barn unnfanget etter slik behandling.

Literature review on cancer risk in children born after fertility treatment suggests increased risk of haematological cancers.

Unlabelled: Medically assisted fertility treatment, including assisted reproductive technology (ART), is increasingly being used and the subsequent child health outcomes are of interest. Some studies have suggested an elevated risk of somatic morbidity, while others have reported an elevated cancer risk. This review summarises the literature on fertility treatments and childhood cancer, based on 23 cohort and case-control studies.

Cancer Risk in Women Treated with Fertility Drugs According to Parity Status-A Registry-based Cohort Study.

Long-term safety of assisted reproductive techniques (ART) is of interest as their use is increasing. Cancer risk is known to be affected by parity. This study examined the risk of cancer after fertility treatment, stratified by women's parity.

Risk of Cancer in Children Conceived by Assisted Reproductive Technology.

Background And Objective: An increasing number of children are born after assisted reproductive technology (ART), and monitoring their long-term health effects is of interest. This study compares cancer risk in children conceived by ART to that in children conceived without.

Methods: The Medical Birth Registry of Norway contains individual information on all children born in Norway (including information of ART conceptions).

Risk of breast cancer following fertility treatment--a registry based cohort study of parous women in Norway.

Despite increasing numbers of women availing themselves of assisted reproductive technology (ART), effects on cancer risk remain unresolved. Given hormonal exposures, breast cancer risk is of particular concern. The aim of this study is to investigate breast cancer risk amongst women giving birth following ART as compared to that amongst women who gave birth without ART.
