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.

Development of a method to achieve antegrade in situ fenestration of endovascular stent grafts in abdominal aortic aneurysms.

Abdominal aortic aneurysm (AAA) is the focal dilation of the terminal aorta, which can lead to rupture if left untreated. Traditional endovascular aneurysm repair techniques are minimally invasive and pose low mortality rates compared with open surgical repair; however, endovascular aneurysm repair procedures face challenges in accommodating variations in the patient's anatomy. Complex aneurysms are defined when the sac extends past the renal arteries or has an insufficient neck landing zone to deploy a traditional endograft.

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.

Identification of the MRTFA/SRF pathway as a critical regulator of quiescence in cancer.

Chemoresistance is a major driver of cancer deaths. One understudied mechanism of chemoresistance is quiescence. We used single cell culture to identify, retrieve, and RNA-Seq profile primary quiescent ovarian cancer cells (qOvCa).

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.

Nitro-fatty acids: promising agents for the development of new cancer therapeutics.

Nitro-fatty acids (NO-FAs) are endogenous pleiotropic lipid mediators regarded as promising drug candidates for treating inflammatory and fibrotic diseases. Over the past two decades, the anti-inflammatory and cytoprotective actions of NO-FAs and several molecular targets have been identified. More recently, preclinical studies have demonstrated their potential as prospective cancer therapeutics with favorable safety and tumor-selective profiles.

Mesenchymal Stem Cell-Conditioned Media-Loaded Microparticles Enhance Acute Patency in Silk-Based Vascular Grafts.

Coronary artery disease leads to over 360,000 deaths annually in the United States, and off-the-shelf bypass graft options are currently limited and/or have high failure rates. Tissue-engineered vascular grafts (TEVGs) present an attractive option, though the promising mesenchymal stem cell (MSC)-based implants face uncertain regulatory pathways. In this study, "artificial MSCs" (ArtMSCs) were fabricated by encapsulating MSC-conditioned media (CM) in poly(lactic-co-glycolic acid) microparticles.

Association of Gestational Diabetes With Subclinical Cardiovascular Disease.

Background: Gestational diabetes mellitus (GDM) is associated with increased long-term risk of cardiovascular disease but the cardiovascular structural and functional changes that contribute to risk are not well understood.

Objectives: The purpose of this study was to determine whether GDM is associated with adverse cardiac remodeling and endothelial dysfunction a decade after delivery, independent of type 2 diabetes.

Methods: Women with deliveries between 2008 and 2009 were initially selected from a prospective clinical cohort.

Carcinoma-associated mesenchymal stem cells promote ovarian cancer heterogeneity and metastasis through mitochondrial transfer.

Ovarian cancer is characterized by early metastatic spread. This study demonstrates that carcinoma-associated mesenchymal stromal cells (CA-MSCs) enhance metastasis by increasing tumor cell heterogeneity through mitochondrial donation. CA-MSC mitochondrial donation preferentially occurs in ovarian cancer cells with low levels of mitochondria ("mito poor").

Spatial molecular profiling of mixed invasive ductal and lobular breast cancers reveals heterogeneity in intrinsic molecular subtypes, oncogenic signatures, and mutations.

Mixed invasive ductal and lobular carcinoma (MDLC) is a rare histologic subtype of breast cancer displaying both E-cadherin positive ductal and E-cadherin negative lobular morphologies within the same tumor, posing challenges with regard to anticipated clinical management. It remains unclear whether these distinct morphologies also have distinct biology and risk of recurrence. Our spatially resolved transcriptomic, genomic, and single-cell profiling revealed clinically significant differences between ductal and lobular tumor regions including distinct intrinsic subtype heterogeneity - e.

A Core NRF2 Gene Set Defined Through Comprehensive Transcriptomic Analysis Predicts Selective Drug Resistance and Poor Multicancer Prognosis.

The nuclear factor erythroid 2-related factor 2-Kelch-like ECH-associated protein 1 (NRF2-KEAP1) pathway plays an important role in the cellular response to oxidative stress but may also contribute to metabolic changes and drug resistance in cancer. However, despite its pervasiveness and important role, most of nuclear factor erythroid 2-related factor 2 (NRF2) target genes are defined in context-specific experiments and analysis, making it difficult to translate from one situation to another. Our study investigates whether a core NRF2 gene signature can be derived and used to represent NRF2 activation in various contexts, allowing better reproducibility and understanding of NRF2.

Use of Natural Language Understanding to Facilitate Surgical De-Escalation of Axillary Staging in Patients With Breast Cancer.

Purpose: Natural language understanding (NLU) may be particularly well equipped for enhanced data capture from the electronic health record given its examination of both content-driven and context-driven extraction.

Methods: We developed and applied a NLU model to examine rates of pathological node positivity (pN+) and rates of lymphedema to determine whether omission of routine axillary staging could be extended to younger patients with estrogen receptor-positive (ER+)/cN0 disease.

Results: We found that rates of pN+ and arm lymphedema were similar between patients age 55-69 years and ≥70 years, with rates of lymphedema exceeding rates of pN+ for clinical stage T1c and smaller disease.

Regenerative Medicine in Gynecology.

The female reproductive tract undergoes dynamic changes across the life span. Congenital abnormalities, life events, and medical interventions can negatively affect the structure and function of reproductive tract organs, resulting in lifelong sequelae. The objective of regenerative gynecology is to discover and promote endogenous mechanisms by which a healthy tissue maintains overall tissue integrity after injury, after disease, or with age.

Inflammatory, metabolic, and endothelial biomarkers before and after pregnancy complications.

Women with gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy (HDP), and preterm birth (PTB) have excess cardiovascular disease compared with those with uncomplicated births, perhaps related to prepregnancy inflammation, dysmetabolism, or endothelial dysfunction. We included 1238 women in the Coronary Artery Risk Development in Young Adults Study (1985-2011) with 2215 births classified according to outcomes (term, uncomplicated births were the referent). Using repeated measures analysis of variance, we estimated prepregnancy and postpregnancy biomarkers, as well as biomarker change according to pregnancy outcomes, adjusted for confounders.
