Human bulk tissue samples comprise multiple cell types with diverse roles in disease etiology. Conventional transcriptome-wide association study approaches predict genetically regulated gene expression at the tissue level, without considering cell-type heterogeneity, and test associations of predicted tissue-level expression with disease. Here we develop MiXcan, a cell-type-aware transcriptome-wide association study approach that predicts cell-type-level expression, identifies disease-associated genes via combination of cell-type-level association signals for multiple cell types, and provides insight into the disease-critical cell type. As a proof of concept, we conducted cell-type-aware analyses of breast cancer in 58,648 women and identified 12 transcriptome-wide significant genes using MiXcan compared …

Despite universal prenatal syphilis screening recommendations and availability of effective antibiotic treatment, syphilis prevalence during pregnancy and the incidence of congenital syphilis have continued to increase in the United States (1,2). Concurrent increases in methamphetamine, injection drug, and heroin use have been described in women with syphilis (3). CDC used data on births that occurred during January 1, 2018-December 31, 2021, from two states (Arizona and Georgia) that participate in the Surveillance for Emerging Threats to Pregnant People and Infants Network (SET-NET) to describe the prevalence of substance use among pregnant persons with syphilis by congenital syphilis pregnancy outcome (defined …

Mommy, Me, And We: Why Black Mothers Have Turned To Doulas, Janessa Harris

Crossings: Swarthmore Undergraduate Feminist Research Journal

Maternal mortality rates have disproportionately affected black mothers for far too long due to the lack of value that black bodies hold in medical spaces. Because of this concerns voiced by black people are often disregarded and ignored until the very last minute. But what if this was changed? This paper will focus on how black mothers have worked against Western medical systems that silence our voices, but instead turn to doulas who work to make these mothers feel seen, heard, and cared for. Through this, we make birthing a careful and collective effort to turn Mommy&Me to Mommy&We.

Take Your Mother’S Ferry: Preimplantation Embryo Development Requires Maternal Karyopherins For Nuclear Transport, Momal Sharif, Laura Detti, Ignatia B Van Den Veyver

Faculty, Staff and Students Publications

The genetic basis of preimplantation embryo arrest is slowly being unraveled. Recent discoveries point to maternally expressed proteins required for cellular functions before the embryonic genome is activated. In this issue of the JCI, Wang, Miyamoto, et al. suggest a critical role for karyopherin-mediated protein cargo transport between oocyte cytoplasm and nucleus. Defective maternal oocyte-expressed human karyopherin subunit α7 (KPNA7) and mouse KPNA2 fail to bind a critical substrate, ribosomal L1 domain-containing protein 1 (RSL1D1), affecting its transport to the nucleus. As shown in embryos of Kpna2-null females, the consequences are disrupted zygotic genome activation and arrest of development. These …

Patient-derived xenograft (PDX) models of breast cancer are an effective discovery platform and tool for preclinical pharmacologic testing and biomarker identification. We established orthotopic PDX models of triple negative breast cancer (TNBC) from the primary breast tumors of patients prior to and following neoadjuvant chemotherapy (NACT) while they were enrolled in the ARTEMIS trial (NCT02276443). Serial biopsies were obtained from patients prior to treatment (pre-NACT), from poorly responsive disease after four cycles of Adriamycin and cyclophosphamide (AC, mid-NACT), and in cases of AC-resistance, after a 3-month course of different experimental therapies and/or additional chemotherapy (post-NACT). Our study cohort includes a …

Trends And Racial/Ethnic Differences In Predictors Of Cervical Cancer Screening Among Us Women Ages 30-64 Years, Itunu O Sokale, Jane R Montealegre, Abiodun O Oluyomi, Aaron P Thrift

Faculty, Staff and Students Publications

BACKGROUND: Cervical cancer screening (CCS) participation has decreased in the United States over the last several decades, contributing to cervical cancer's sustained incidence and mortality. This study examined recent trends and racial/ethnic differences in predictors of CCS uptake among US women.

METHODS: We analyzed combined data from the 2016 to 2020 Behavioral Risk Factor Surveillance System (BRFSS) and included 235,713 women ages 30 to 64 years without a hysterectomy. We used simple linear regression to assess trends over time and multivariable logistic regression models to evaluate racial/ethnic differences in predictors of up-to-date CCS.

RESULTS: We found little change in CCS …

We evaluated the association of disease outcome with T cell immune-related characteristics and T cell receptor (TCR) repertoire in malignant ascites from patients with high-grade epithelial ovarian cancer. Ascitic fluid samples were collected from 47 high-grade epithelial ovarian cancer patients and analyzed using flow cytometry and TCR sequencing to characterize the complementarity determining region 3 TCR β-chain. TCR functions were analyzed using the McPAS-TCR and VDJ databases. TCR clustering was implemented using Grouping of Lymphocyte Interactions by Paratope Hotspots software. Patients with poor prognosis had ascites characterized by an increased ratio of CD8+ T cells to regulatory T cells, which …

Assessing The Impact Of Pregnancy And Birth Factors On The Maternal And Infant Microbiota, Kait F. Al, Laura Allen, Samantha Bedell, Jeremy P. Burton, Barbra De Vrijer

Obstetrics & Gynaecology Publications

Background: The microbiota acquired at birth is known to play an intimate role in later life health and disease and has been shown to be affected by the mode of birth. There has been recent interest in microbiota correction by maternal vaginal seeding in Cesarean section-born infants; however, the safety of this practice has been debated. The aim of this study was to assess how other factors, such as timing of sampling, maternal obesity, vaginal Group B Streptococcus colonization (GBS), and antibiotic exposure, affect the maternal and infant microbiota.

Methods: Maternal vaginal and saliva samples were collected at three time …

Telecontraception – A Way To Address A Health Care Disparity A Preliminary Literature Review, Pamela D. Parker

MedEd Teaching Certificate Program

Unintended pregnancy continues to be a significant personal and public health concern in all countries. In 2015-2019 there were 121 million unintended pregnancies annually, corresponding to a global rate of 64 unintended pregnancies per 1000 women aged 15-49 years. While there are multiple contraception options available in general, access to them can be limited by a myriad of factors. Over the past two decades there has been an increase in mail order services for contraception that bypasses the traditional clinician office visit-examination-pharmacy model, thus increasing access for many women (and men). These companies have been proven to provide safe, convenient …

The Efficacy Of Treatment Of Symptoms Of Polycystic Ovarian Syndrome And Associated Health Risks Using Insulin Sensitizers: A Meta-Analysis, Isabella J. Wong

Honors Undergraduate Theses

Polycystic Ovarian Syndrome (PCOS) is common among women of reproductive age (ages 15-49), and it can put patients at higher risk for diseases such as type II diabetes or coronary heart disease. While the mechanisms behind PCOS are poorly understood, it is diagnosed using two characteristics: hyperandrogenism and anovulation. Once diagnosed, many patients are also tested for insulin resistance (IR). While IR is thought of as a symptom of PCOS, this study will examine the effects of treatment of IR to manage symptoms of PCOS rather than treatment of hyperandrogenism. This meta-analysis used data from studies previously published by searching …

Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder

Undergraduate Honors Theses

The following project involves a systematic review of the scientific literature on neural and biological changes of mothers and fathers in parenthood. Until very recently, little scientific research was devoted to studying how bearing children affects a man or woman’s long-term biology. Over the last twenty years, studies of neuroplastic changes in new mothers show specific neural mechanisms responsible for altering the behaviors of mothers during and after pregnancy. These changes in neuroplasticity alter behavior in such a way that led to mothers requiring less sleep and being more prone to hearing the cries of their children. In addition to …

The Ethical Dilemma Of Whether Or Not To Withhold Life Sustaining Treatments For Newborns, Chloe G. Payne

OUR Journal: ODU Undergraduate Research Journal

Deeply complex ethical questions can arise when deciding whether to continue or stop life-sustaining treatments for critically ill newborns. Various factors that can influence these decisions are explored, such as the expected quality of life for the newborn, the resources that the family and hospital have at their disposal, and the role of religious beliefs. Emphasis is placed on the importance of striking a balance between the child's best interest, the autonomy of the parents, and the medical facts. The potential psychological and physical consequences for parents who decide to stop treatment, which often results in the loss of their …
