Objective: The aim of the study was to determine if VBAC is associated with an increased risk of OASIs.

Study Design: This was a retrospective cohort study of liveborn deliveries from 2018 to 2022 within a large, multihospital academic health system.

Adjuvant Therapy in Early Uterine Serous Carcinoma.

Objective: Uterine serous carcinoma (USC) is a rare diagnosis but associated with high mortality. There is limited data to guide adjuvant treatment decisions in early stage disease. The purpose of this study is to evaluate the impact of adjuvant therapy on recurrence-free survival (RFS) and overall survival (OS) in early stage USC.

Mode of Delivery and Subsequent Motor Function in Children With Myelomeningocele Without In Utero Repair.

Objective: To assess the association between mode of delivery and 2-year motor function in children with prenatal diagnosis of myelomeningocele.

Methods: A multisite retrospective cohort study of children with myelomeningocele across 14 NAFTNet (North American Fetal Therapy Network) centers born between 2007 and 2020 who had a physical examination available at 2 years of life. Exclusion criteria were in utero myelomeningocele repair, postnatal myelomeningocele diagnosis, missing data on fetal presentation at delivery, and contraindications to labor.

Provider perspectives on caring for patients with limited English proficiency-a national survey of the Society of Gynecologic Oncology.

Background: In diversity, equity and inclusion research, overcoming barriers in language discordant patient care is one of the largest and most challenging gaps. It is well established that patients with limited English proficiency (LEP) have higher rates of misdiagnosis, medical errors, and serious adverse events, and recommended best practices for LEP patient care are often not followed.

Objective: Our team sought to elicit provider perspectives regarding the barriers they face in caring for LEP patients-especially the unique challenges faced when caring for patients with complex and sensitive diagnoses such as gynecologic cancer.

Triple-Negative Breast Cancer: Radiologic-Pathologic Correlation.

Triple-negative breast cancers (TNBCs) are invasive carcinomas that lack ER and PR expression and also lack amplification or overexpression of HER2. Triple-negative breast cancers are histopathologically diverse, with the majority classified as invasive breast carcinomas of no special type with a basal-like profile. Triple-negative breast cancer is the most aggressive molecular subtype of invasive breast carcinoma, with the highest rates of stage-matched mortality and regional recurrence.

A Radiomic-Clinical Model of Contrast-Enhanced Mammography for Breast Cancer Biopsy Outcome Prediction.

Rationale And Objectives: In the USA over 1 million breast biopsies are performed annually. Approximately 9.6% diagnostic exams were given Breast Imaging Reporting and Data System (BI-RADS) ≥4A, most of which are 4A/4B.

Enhanced D614G and Omicron Variants Antibody Persistence in Infants at 2 Months of Age Following Maternal mRNA Booster Vaccination During Pregnancy or Postpartum.

Background: Following maternal COVID-19 vaccination, the persistence of antibodies in sera and breast milk for mothers and infants is not well characterized. We sought to describe the persistence of antibodies through 2 months after delivery in maternal and infant serum and breast milk following maternal COVID-19 mRNA vaccination and to examine differences by receipt of booster dose during pregnancy or postpartum.

Methods: This is a prospective cohort study with enrollment from July 2021 to January 2022 at 9 US academic sites.

Consensus Preconception Educational Domains for People With Mobility Disabilities: A Delphi Study.

Background: Preconception health education is critical to improve pregnancy and neonatal outcomes, but people with mobility disabilities have specific, often unique issues related to preparing for pregnancy. This study sought to develop consensus-based domains for a preconception education curriculum for people with mobility disabilities.

Methods: We used a mixed methods approach, including a literature review and a Delphi method to develop consensus.

Perioperative Opioid Use in Urogynecologic Mesh Removal.

Importance: Forty percent of patients with urogynecologic mesh pain complications are taking narcotics.

Objectives: We aimed to compare comorbidities and pain scores between patients with and without narcotic use and assess postoperative narcotic use rates.

Study Design: This was a secondary analysis of a prospective cohort study of patients undergoing urogynecologic mesh removal.

An Approach for Improving the Detection and Quantitation of Buprenorphine and Its Metabolites in Maternal and Neonatal Hair.

Background: Buprenorphine (BUP) use is prevalent in pregnant women with opioid use disorder (OUD). Drug monitoring during pregnancy is critical for optimizing dosing regimen and achieving the desired clinical outcomes. Hair can be used as a critical biological matrix for monitoring long-term exposure to drugs.

Unveiling non-coding variants: synergising RNA sequencing and DNA sequencing for enhanced molecular diagnosis.

Background: Pathogenic variants in the gene are associated with dystrophinopathy including Duchenne and Becker muscular dystrophy (DMD/BMD). Targeted gene, gene panels, exomes and genome sequencing have advanced genetic diagnostics, yet some cases remain elusive.

Methods: We performed total RNA sequencing (RNAseq) on muscle biopsy from 13 male patients with a clinical diagnosis of DMD/BMD.

Vaginal administration of 17-alpha hydroxyprogesterone caproate appears to be safe in non-pregnant female rats and rabbits.

Intramuscular (250 mg once weekly) or subcutaneous (275 mg once weekly) injections of 17-hydroxyprogesterone caproate (17-OHPC) has been utilised to prevent recurent spontaneous preterm birth in pregnant women with a short cervix or those with a prior preterm birth but its efficacy in these conditions has been questioned. It is unclear whether adequate concentrations of 17-OHPC reach the suspected target organs such as the cervix and uterus following either IM or SC administration.The objective of this study was to determine feasibility and safety of vaginal administration of 17-OHPC in adult female Sprague Dawley rats and female New Zealand rabbits.
