Fetal alcohol spectrum disorders (FASDs) are leading causes of neurodevelopmental disability but cannot be diagnosed early in utero. Because several microRNAs (miRNAs) are implicated in other neurological and neurodevelopmental disorders, the effects of EtOH exposure on the expression of these miRNAs and their target genes and pathways were assessed. In women who drank alcohol (EtOH) during pregnancy and non-drinking controls, matched individually for fetal sex and gestational age, the levels of miRNAs in fetal brain-derived exosomes (FB-Es) isolated from the mothers’ serum correlated well with the contents of the corresponding fetal brain tissues obtained after voluntary pregnancy termination. In six …

Twist1 Drives Cytotoxic Cd8+ T-Cell Exhaustion Through Transcriptional Activation Of Cd274 (Pd-L1) Expression In Breast Cancer Cells, Xiaobin Yu, Jianming Xu

Faculty, Staff and Students Publications

In breast cancer, epithelial-mesenchymal transition (EMT) is positively associated with programmed death ligand 1 (PD-L1) expression and immune escape, and TWIST1 silences ERα expression and induces EMT and cancer metastasis. However, how TWIST1 regulates PD-L1 and immune evasion is unknown. This study analyzed TWIST1 and PD-L1 expression in breast cancers, investigated the mechanism for TWIST1 to regulate PD-L1 transcription, and assessed the effects of TWIST1 and PD-L1 in cancer cells on cytotoxic CD8+ T cells. Interestingly, TWIST1 expression is correlated with high-level PD-L1 expression in ERα-negative breast cancer cells. The overexpression and knockdown of TWIST1 robustly upregulate and downregulate PD-L1 …

Pain Outcomes In Adolescents With Surgically Confirmed Endometriosis: A Single Site Retrospective Cohort Analysis, Madeline Ross, Samantha Janssen, Priya Suvarna, Adam Booser, Ashli Lawson

Research Days

Background: In adolescents with significant dysmenorrhea, empiric therapy via analgesics and hormonal medications is considered gold standard. However, those with refractory pain may have endometriosis. Thus, it is recommended to engage in shared medical decision making with these patients regarding diagnostic laparoscopy. If endometriosis is detected intraoperatively, these lesions are often fulgurated or excised. There currently is a paucity of data regarding the benefits of diagnostic laparoscopy and destruction of lesions in the adolescent population.

Objectives/Goal: To evaluate long-term pain management outcomes and care patterns in adolescent patients undergoing surgical evaluation for endometriosis.

Methods/Design: This was a single-site, retrospective cohort …

Combining an immune checkpoint inhibitor with batiraxcept (AVB-S6-500), an AXL inhibitor that acts via selective binding to growth arrest-specific protein 6 (GAS6), may improve anti-tumor immunity in platinum-resistant ovarian cancer (PROC). This phase 1b trial of durvalumab in combination with escalating doses of batiraxcept enrolled patients with recurrent PROC (NCT04019288). The primary objective was to determine the toxicity profile of the combination. Eleven patients were enrolled on the trial. No dose-limiting toxicities were observed, and no objective responses were noted. Median progression free survival (PFS) was 1.81 months (95% confidence interval (CI) 1.71–2.40), and median overall survival (OS) was 4.53 …

Characteristics And Clinical Outcomes Of Iud Insertion Under Conscious Sedation In Pediatric And Adolescent Patients, Alleana Corpin, Madeline Ross, Anne-Marie Priebe, Ashli A. Lawson

Research Days

Intrauterine devices (IUDs) are a favorable option for adolescents for contraception and menstrual suppression. However, few choose this option citing anxiety and concern for pain related to insertion procedure. Our institution proposes utilizing conscious sedation techniques for anxiolysis and analgesia during IUD insertion. The objective of this study was to identify characteristics of teens choosing conscious sedation for this procedure and likelihood of successful insertion.

Key Words: Intrauterine device (IUD), adolescent, conscious sedation

Case Of An Adolescent Girl With Familial Vulvar Leiomyoma, Madeline Ross, Charlene Dekonenko, Rebecca Rentea, Tazim Dowlut-Mcelroy

Research Days

Background

While uterine leiomyomas remain a common occurrence affecting nearly 30% of adult women above 35yo, leiomyomas can arise anywhere smooth muscle cells are located in the body. Vulvar leiomyomas are a particularly rare diagnosis, often misdiagnosed as Bartholin gland cyst, comprising 0.07% of vulvar tumors, and thought to arise from smooth muscle within the round ligament, erectile tissue, and dartos muscle. Even more rare is the presentation of vulvar leiomyoma in the adolescent population and family history of vulvar leiomyoma.

Case

We present the case of a 16yo girl who noticed a painless vulvar mass that had increased in …

Development Of An Endometriosis Toolkit To Support Clinicians In Providing Quality Care For Women, Rachel Hasbun

Doctor of Nursing Practice (DNP) Projects

Abstract

Background: Endometriosis is the abnormal growth of endometrium-like tissue outside the uterine cavity, affecting approximately 11% of women in the United States during their reproductive years. Diagnostic challenges stem from its varied clinical presentations, reliance on laparoscopy for definitive diagnosis, and limited awareness among practitioners and patients, potentially leading to diagnostic delays of up to 13 years.

Problem: The complexities of diagnosing endometriosis in primary care and specialty settings, combined with limited provider awareness and a lack of comprehensive resources, hinder timely and accurate identification. This leads to suboptimal treatment and care for women affected by the condition.

Basal progenitor cells are crucial for maintaining foregut (the esophagus and forestomach) homeostasis. When their function is dysregulated, it can promote inflammation and tumorigenesis. However, the mechanisms underlying these processes remain largely unclear. Here, we employ genetic mouse models to reveal that Jag1/2 regulate esophageal homeostasis and foregut tumorigenesis by modulating the function of basal progenitor cells. Deletion of Jag1/2 in mice disrupts esophageal and forestomach epithelial homeostasis. Mechanistically, Jag1/2 deficiency impairs activation of Notch signaling, leading to reduced squamous epithelial differentiation and expansion of basal progenitor cells. Moreover, Jag1/2 deficiency exacerbates the deoxycholic acid (DCA)-induced squamous epithelial injury and …

The unexplained protective effect of childhood adiposity on breast cancer risk may be mediated via mammographic density (MD). Here, we investigate a complex relationship between adiposity in childhood and adulthood, puberty onset, MD phenotypes (dense area (DA), non-dense area (NDA), percent density (PD)), and their effects on breast cancer. We use Mendelian randomization (MR) and multivariable MR to estimate the total and direct effects of adiposity and age at menarche on MD phenotypes. Childhood adiposity has a decreasing effect on DA, while adulthood adiposity increases NDA. Later menarche increases DA/PD, but when accounting for childhood adiposity, this effect is attenuated. …
