The Association Between Periconceptual Maternal Dietary Patterns and Miscarriage Risk in Women With Recurrent Miscarriages: A Multicentre Cohort Study.

Objective: To examine the association between periconceptual maternal diet and miscarriage risk among women with recurrent miscarriages.

Design: Prospective multicentre cohort study (Tommy's Net).

Setting: Three university hospital research centres in the United Kingdom.

Cognitive and academic outcomes of large-for-gestational-age babies born at early term: A systematic review and meta-analysis.

Introduction: Early induction of labor (37-38 gestational weeks) in large-for-gestational-age infants may reduce perinatal risks such as shoulder dystocia, but it may also increase the long-term risks of reduced cognitive abilities. This systematic review aimed to evaluate the cognitive and academic outcomes of large-for-gestational-age children born early term versus full term (combined or independent exposures).

Material And Methods: The protocol was registered in the PROSPERO database under the registration no.

Improving Miscarriage Prevention Research: a survey exploring the expectations of service users and stakeholders (IMPRESS) - a study protocol for a UK-based survey.

Introduction: Interventional clinical trials in recurrent miscarriage use varying expected effect sizes to inform their sample size calculations. Often these are not informed by what stakeholders consider a meaningful treatment effect. Adaptive trial designs may integrate stakeholder views on trial success and futility but the criteria to inform this is lacking.

Lessons learned from bovine subclinical endometritis: A systematic review exploring its potential relevance to chronic endometritis in women.

Chronic endometritis (CE) in humans is asymptomatic inflammation of the endometrium, associated with poor reproductive outcomes. Similarly asymptomatic endometrial inflammation in cows, termed subclinical endometritis (SCE), is associated with adverse reproductive outcomes. While the pathophysiology and treatment options for CE in humans remains poorly defined, the financial implications of SCE in dairy cows mean it has been intensively researched.

Accuracy of antenatal ultrasound in predicting large-for-gestational-age babies: population-based cohort study.

Background: Pregnancies with large-for-gestational-age fetuses are at increased risk of adverse maternal and neonatal outcomes. There is uncertainty about how to manage birth in such pregnancies. Current guidelines recommend a discussion with women of the pros and cons of options, including expectant management, induction of labor, and cesarean delivery.

Multivariable prediction models for fetal macrosomia and large for gestational age: A systematic review.

Background: The identification of large for gestational age (LGA) and macrosomic fetuses is essential for counselling and managing these pregnancies.

Objectives: To systematically review the literature for multivariable prediction models for LGA and macrosomia, assessing the performance, quality and applicability of the included model in clinical practice.

Search Strategy: MEDLINE, EMBASE and Cochrane Library were searched until June 2022.

Fetal loss and long-term maternal morbidity and mortality: A systematic review and meta-analysis.

Background: Evidence suggests common pathways between pregnancy losses and subsequent long-term maternal morbidity, rendering pregnancy complications an early chronic disease marker. There is a plethora of studies exploring associations between miscarriage and stillbirth with long-term adverse maternal health; however, these data are inconclusive.

Methods And Findings: We systematically searched MEDLINE, EMBASE, AMED, BNI, CINAHL, and the Cochrane Library with relevant keywords and MeSH terms from inception to June 2023 (no language restrictions).

The endometrial microbiota and early pregnancy loss.

The human endometrium is a dynamic entity that plays a pivotal role in mediating the complex interplay between the mother and developing embryo. Endometrial disruption can lead to pregnancy loss, impacting both maternal physical and psychological health. Recent research suggests that the endometrial microbiota may play a role in this, although the exact mechanisms are still being explored, aided by recent technological advancements and our growing understanding of host immune responses.

Lived experience of recurrent miscarriage: women and their partners' experience of subsequent pregnancy and support within an NHS specialist clinic - a qualitative study.

Objective: This study aims to describe the lived experiences of couples with a history of recurrent miscarriage in subsequent pregnancies and their perception of clinic support and cytogenetic investigations.

Design: A qualitative interview study with a phenomenological approach. Semistructured interviews were conducted using video conferencing software.

Routine use of cell salvage during cesarean section: A practice evaluation.

Introduction: Intraoperative cell salvage is a well-documented alternative to donor blood transfusion given the scarcity of donor blood pools and the incumbent risk of allogenic blood transfusion. Its use in obstetrics has been limited by concern over fetal alloimmunization due to the risk of fetomaternal hemorrhage. However, there are a paucity of studies reporting on outcome.

Preconceptual administration of doxycycline in women with recurrent miscarriage and chronic endometritis: protocol for the Chronic Endometritis and Recurrent Miscarriage (CERM) trial, a multicentre, double-blind, placebo-controlled, adaptive randomised trial with an embedded translational substudy.

Introduction: Recurrent miscarriage is a common condition with a substantial associated morbidity. A hypothesised cause of recurrent miscarriage is chronic endometritis (CE). The aetiology of CE remains uncertain.

The role of small extracellular vesicle-miRNAs in endometriosis.

Endometriosis is defined by the presence of extrauterine endometrial-like tissue, which can cause pain and infertility in 10% of reproductive-age women. To date, the pathogenesis is poorly understood resulting in significant diagnostic delays and poor therapeutic outcomes in many women. Small extracellular vesicles (sEVs) (<200 nm) are cell-derived vesicles containing molecules that can influence gene expression and behaviour in target cells.

Heparin for women with recurrent miscarriage and inherited thrombophilia (ALIFE2): an international open-label, randomised controlled trial.

Background: Anticoagulant therapy might reduce the number of miscarriages and adverse pregnancy outcomes in women with recurrent pregnancy loss and inherited thrombophilia. We aimed to assess use of low-molecular-weight heparin (LMWH) versus standard care in this population.

Methods: The ALIFE2 trial was an international open-label, randomised controlled trial undertaken in hospitals in the UK (n=26), the Netherlands (n=10), the USA (n=2), Belgium (n=1), and Slovenia (n=1).

Fertility preservation, its effectiveness and its impact on disease status in pre-menopausal women with breast cancer: A systematic review and meta-analysis.

Introduction: Preservation of reproductive function is a key concern for many premenopausal women with breast cancer, given the known gonadotoxic effects of treatments. The present systematic review aimed to investigate the effectiveness and safety of fertility preservation strategies in pre-menopausal women with breast cancer.

Methods: Primary research assessing fertility preservation strategies of any type was identified.

A core outcome set for trials in miscarriage management and prevention: An international consensus development study.

Objective: To develop core outcome sets (COS) for miscarriage management and prevention.

Design: Modified Delphi survey combined with a consensus development meeting.

Setting: International.

ESHRE guideline: recurrent pregnancy loss: an update in 2022.

Study Question: What are the updates for the recommended management of women with recurrent pregnancy loss (RPL) based on the best available evidence in the literature from 2017 to 2022?

Summary Answer: The guideline development group (GDG) updated 11 existing recommendations on investigations and treatments for RPL, and how care should be organized, and added one new recommendation on adenomyosis investigation in women with RPL.

What Is Known Already: A previous ESHRE guideline on RPL was published in 2017 and needs to be updated.

Study Design Size Duration: The guideline was developed and updated according to the structured methodology for development and update of ESHRE guidelines.

The impact of maternal obesity on in vivo uterine contractile activity during parturition in the rat.

Maternal obesity is associated with increased risk of prolonged and dysfunctional labor and emergency caesarean section. To elucidate the mechanisms behind the associated uterine dystocia, a translational animal model is required. Our previous work identified that exposure to a high-fat, high-cholesterol (HFHC) diet to induce obesity down-regulates uterine contractile associated protein expression and causes asynchronous contractions ex vivo.

Ethnic group and reason for assisted reproductive technology failure: analysis of the Human Fertilisation and Embryology Authority registry data from 2017 to 2018.

Objective: To understand how the risk of different assisted reproductive technology (ART) failure types varies by ethnic group and explore the role of mediation by maternal age and suspected etiology.

Design: An observational study of 48,750 women who undertook treatment with ART in the United Kingdom between January 2017 and December 2018.

Setting: The Human Fertilisation and Embryology Authority national ART registry of the United Kingdom.

Induction of labour for predicted macrosomia: study protocol for the 'Big Baby' randomised controlled trial.

Introduction: Large-for-gestational age (LGA) fetuses have an increased risk of shoulder dystocia. This can lead to adverse neonatal outcomes and death. Early induction of labour in women with a fetus suspected to be macrosomic may mitigate the risk of shoulder dystocia.

Predictive Models for Estimating the Probability of Successful Vaginal Birth After Cesarean Delivery: A Systematic Review.

Objective: To systematically review all studies that developed or validated a vaginal birth after cesarean (VBAC) prediction model.

Data Sources: MEDLINE, EMBASE, CINAHL, Cochrane Library, and ClinicalTrials.gov were searched from inception until February 2022.

Miscarriage syndrome: Linking early pregnancy loss to obstetric and age-related disorders.

Upon embryo implantation, the uterine mucosa - the endometrium - transforms into a robust decidual matrix that accommodates the fetal placenta throughout pregnancy. This transition is driven by the differentiation of endometrial fibroblasts into specialised decidual cells. A synchronised influx of circulating natural killer (NK) cells and bone marrow-derived mesenchymal stem/progenitor cells (BM-MSC) is pivotal for decidual homeostasis and expansion in early pregnancy.

Electronic Patient Reported Outcomes for Miscarriage Research in Tommy's Net.

Unlabelled: The Tommy's National Centre for Miscarriage Research aims to support the diagnosis and treatment for couples suffering from recurrent miscarriage. Tommy's Net is an electronic data gathering tool, collecting miscarriage data and links with hospital Clinical Information System databases. The gathering of patient reported data is an important aspect, especially as data relating to pregnancy and miscarriage events are often left unreported.

Online health information on induction of labour: A systematic review and quality assessment study.

Objectives: Many women will seek information online about induction of labour. However, the quality of the available information varies greatly and there are no regulations regarding the content that is published. Our objective was to systematically evaluate the quality of online health information on induction of labour.
