The cellular junctional architecture remodeling by Listeria adhesion protein-heat shock protein 60 (LAP-Hsp60) interaction for Listeria monocytogenes (Lm) passage through the epithelial barrier is incompletely understood. Here, using the gerbil model, permissive to internalin (Inl) A/B-mediated pathways like in humans, we demonstrate that Lm crosses the intestinal villi at 48 h post-infection. In contrast, the single isogenic (lap− or ΔinlA) or double (lap−ΔinlA) mutant strains show significant defects. LAP promotes Lm translocation via endocytosis of cell-cell junctional complex in enterocytes that do not display luminal E-cadherin. In comparison, InlA facilitates …

Makara Journal of Health Research

Background: This study aimed to investigate the relationship between plasma fluoride and hemoglobin levels, glutathione peroxidase (GPx) activity, and abortion among rural and urban pregnant women from Settat province (Morocco).

Methods: Blood samples were collected from rural pregnant women who had not undergone abortion (N = 224), rural pregnant women who had an abortion (N = 38), urban pregnant women who had not undergone abortion (N = 163), and urban pregnant women who had an abortion (N = 14).

Results: The highest (p < 0.01) plasma fluoride levels and the lowest (p < 0.01) GPx activity were observed in rural pregnant women. In all participants, plasma fluoride levels were significantly higher (p < 0.001), and the GPx activity was significantly (p < 0.001) lower in pregnant women who had an abortion compared with those who did not undergo such process. No significant difference was observed between the hemoglobin levels of all participants. Furthermore, abortion was positively correlated with plasma fluoride levels (p < 0.001) and negatively correlated with GPx activity (p < 0.001) in rural participants.

Conclusions: Rural pregnant women had higher plasma …

Tools for assessing multiple exposures across several domains (e.g., physical, chemical, and social) are of growing importance in social and environmental epidemiology because of their value in uncovering disparities and their impact on health outcomes. Here we describe work done within the Environmental influences on Child Health Outcomes (ECHO)-wide Cohort Study to build a combined exposure index. Our index considered both environmental hazards and social stressors simultaneously with national coverage for a 10-year period. Our goal was to build this index and demonstrate its utility for assessing differences in exposure for pregnancies enrolled in the ECHO-wide Cohort Study. Our unitless …

Climate Change Imperils Pediatric Health: Child Advocacy Through Fossil Fuel Divestment., Sandra H. Jee, Elizabeth Friedman, Ruth A. Etzel, Vi T. Nguyen, Todd L. Sack, Kathi J. Kemper

Manuscripts, Articles, Book Chapters and Other Papers

Climate change poses an existential threat to children's health. Divestment of ownership stakes in fossil fuel companies is one tool available to pediatricians to address climate change. Pediatricians are trusted messengers regarding children's health and therefore bear a unique responsibility to advocate for climate and health policies that affect children. Among the impacts of climate change on pediatric patients are allergic rhinitis and asthma; heat-related illnesses; premature birth; injuries from severe storms and fires; vector-borne diseases; and mental illnesses. Children are disproportionately affected as well by climate-related displacement of populations, drought, water shortages, and famine. The human-generated burning of fossil …

Effects Of Pregnancy And Progesterone On Atrial Fibrillation, Heloisa M. Rutigliano

Browse all Datasets

Atrial Fibrillation (AF) is the most common cardiac arrythmia in adults with likely sex-specific risk factors. Female sex hormones may be important in modulating risk for atrial fibrillation. We hypothesize that pregnancy and progesterone (P4), a hormone found in high levels during pregnancy with abrupt withdrawal immediately after parturition, modulates AF susceptibility in female goats. Cardiac specific TGF-?1 transgenic female goats and age-matched wild-type (WT) female goats were utilized. Pacemakers were implanted in all animals for continuous arrhythmia monitoring and AF inducibility. AF inducibility was evaluated using 5 separate 10 s bursts of atrial pacing (160 - 200 ms). In …

Community & Environmental Health Faculty Publications

Background: Breastfeeding is proposed to play a role in reducing the risk of obesity throughout life. Kuwait has an extremely high prevalence of childhood obesity (45% of adolescents are overweight/obese) and extremely low breastfeeding indicators, particularly exclusive breastfeeding. In fact, little is known about the association between breastfeeding and obesity from Kuwait and the broader Middle East.

Aims: To estimate the prevalence of overweight/obesity in female adolescents in Kuwait and assess its association with breastfeeding during infancy.

Methods: This is a cross-sectional study that included 775 girls randomly selected from public and private high schools in Kuwait. The primary exposure …

Human Movement Sciences Faculty Publications

Polychlorinated biphenyls (PCBs) are persistent environmental organic pollutants known to have detrimental health effects. Using a mouse model, we previously demonstrated that PCB126 exposure before and during pregnancy and throughout the perinatal period adversely affected offspring glucose tolerance and/or body composition profiles. The purpose of this study was to investigate the glucose tolerance and body composition of offspring born to dams exposed to PCB126 during the nursing period only. Female ICR mice were bred, and half of the dams were exposed to either vehicle (safflower oil) or 1 µmole PCB126 per kg of body weight via oral gavage on postnatal …

Risk-Factor Induced Changes In The Breast Microenvironment Facilitate Inflammatory Breast Cancer Progression And Lymphovascular Invasion, Wintana Balema, Wintana Balema

Dissertations & Theses (Open Access)

Inflammatory breast cancer (IBC) is a rapidly progressing, rare and highly lethal form of breast cancer. IBC is a clinical diagnosis, requiring >1/3 involvement on the affected breast and/or skin by erythema, and disease onset of < 6 months. The clinical symptoms of IBC vary in severity and presentation, these include redness, warmth, skin thickening and bruised or pink/purple discoloration appearance and skin changes such as peau d’orange. These skin symptoms are not attributed to inflammation, rather IBC is characterized by florid lymphovascular tumor emboli clogging dermal lymphatics. This leads to “classic” symptoms of breast swelling and skin edema or discoloration. To date, unique genomic drivers which differentiate IBC from non-IBC invasive breast cancers have not been identified highlighting a role for the microenvironment. Several epidemiological studies have unveiled subtype-specific risk factors associated with IBC that are known to alter the microenvironment. Obesity is an established risk factor for all subtypes of IBC. Never-breastfeeding increases risk for developing the most aggressive, triple-negative IBC. Further, never breastfeeding is associated with later clinical stage and worse outcomes. We worked to model these overlapping risk factors to understand microenvironment changes that may lead to the lymphatic change’s indicative of IBC.

First, we investigated the association of a “classic” triad of clinical IBC signs with overall survival among patients to demonstrate the most overt clinical findings of lymphatic involvement were impacting prognosis. We evaluated a triad of IBC signs, including swollen involved breast, nipple change, and diffuse skin change, using breast medical photographs from patients enrolled on a prospective IBC registry. We reported that the …

Faculty Research 2022

BACKGROUND: The diagnostic rate of Mendelian disorders in sequencing studies continues to increase, along with the pace of novel disease gene discovery. However, variant interpretation in novel genes not currently associated with disease is particularly challenging and strategies combining gene functional evidence with approaches that evaluate the phenotypic similarities between patients and model organisms have proven successful. A full spectrum of intolerance to loss-of-function variation has been previously described, providing evidence that gene essentiality should not be considered as a simple and fixed binary property.

METHODS: Here we further dissected this spectrum by assessing the embryonic stage at which homozygous …

Faculty Research 2022

Technological advances in both genome sequencing and prenatal imaging are increasing our ability to accurately recognize and diagnose Mendelian conditions prenatally. Phenotype-driven early genetic diagnosis of fetal genetic disease can help to strategize treatment options and clinical preventive measures during the perinatal period, to plan in utero therapies, and to inform parental decision-making. Fetal phenotypes of genetic diseases are often unique and at present are not well understood; more comprehensive knowledge about prenatal phenotypes and computational resources have an enormous potential to improve diagnostics and translational research. The Human Phenotype Ontology (HPO) has been widely used to support diagnostics and …

Hematology/Oncology and Stem Cell Therapy

The management of immune thrombocytopenic purpura (ITP) involves several lines of therapy such as corticosteroids and intravenous immunoglobulin. With the emergence of novel therapies such as thrombopoietin receptor agonists (TPO-RAs), there has been a shift in treatment modalities. Eltrombopag and romiplostim have proven to be effective in the management of ITP through clinical studies, but their safety in pregnancy remains uncertain. The purpose of the study is to review the literature to evaluate the safety of TPO-RAs in pregnant women. Ten case reports and a cohort study pertaining to the use of TPO-RAs in pregnancy were obtained. According to the …

A Serological Analysis Of Sars-Cov-2 Infection In The Obstetric Population, Sophia Rose

CMC Senior Theses

In December 2019, the surfacing and spread of a novel coronavirus, SARS-CoV-2, resulted in the global COVID-19 pandemic. As a viral antigen, SARS-CoV-2 poses a particular threat to the obstetric population due to physiological and immunological changes that women face during pregnancy. While recent studies have found that SARS-CoV-2 may have better clinical outcomes as compared to other betacoronaviruses, adverse pregnancy events such as ICU admission, preeclampsia, and/or preterm birth have been associated with COVID-19. Progress has been made in better understanding the pathophysiology of SARS-CoV-2 in pregnancy, but there is still much to be known about the interaction …

Variations, Validations, Degradations, And Noninvasive Determination Of Pregnancy Using Fecal Steroid Metabolites In Free-Ranging Pronghorn, Cole A. Bleke, Eric M. Gese, Susannah S. French

USDA Wildlife Services: Staff Publications

Pregnancy status is a key parameter used to assess reproductive performance of a species as it represents a starting point for measuring vital rates. Vital rates allow managers to determine trends in populations such as neonate survival and recruitment; two important factors in ungulate population growth rates. Techniques to determine pregnancy have generally involved capture and restraint of the animal to obtain blood samples for determining serum hormone levels. Non-invasive pregnancy assessment, via feces, eliminates any hazards between handler and animal, as well as removes handling-induced physiological biases. Using noninvasive fecal sampling, we conducted hormone validations, investigated pregnancy rates, and …

Black And White Health Disparities: Racial Bias In American Healthcare, Yasmeen Almomani

Bridges: An Undergraduate Journal of Contemporary Connections

This paper explores the historical implications of race in American society that have led to implicit racism in the healthcare system. Racial bias in healthcare against Black people is a factor in the health disparities between Black and white people in America, such as the gap in life expectancy, infant death, and maternal mortality. Black people are more likely to report racial discrimination from healthcare providers, which is a reason for the decreased quality of care received. The past justifications of slavery, the Tuskegee syphilis study, and the medical experimentations on Black women are horrifying but were considered acceptable in …

Endometrial Receptivity And Implantation Require Uterine Bmp Signaling Through An Acvr2a-Smad1/Smad5 Axis., Diana Monsivais, Takashi Nagashima, Renata Prunskaite-Hyyryläinen, Kaori Nozawa, Keisuke Shimada, Suni Tang, Clark Hamor, Julio E Agno, Fengju Chen, Ramya P Masand, Steven L Young, Chad J Creighton, Francesco J Demayo, Masahito Ikawa, Se-Jin Lee, Martin M Matzuk

Faculty Research 2021

During early pregnancy in the mouse, nidatory estrogen (E2) stimulates endometrial receptivity by activating a network of signaling pathways that is not yet fully characterized. Here, we report that bone morphogenetic proteins (BMPs) control endometrial receptivity via a conserved activin receptor type 2 A (ACVR2A) and SMAD1/5 signaling pathway. Mice were generated to contain single or double conditional deletion of SMAD1/5 and ACVR2A/ACVR2B receptors using progesterone receptor (PR)-cre. Female mice with SMAD1/5 deletion display endometrial defects that result in the development of cystic endometrial glands, a hyperproliferative endometrial epithelium during the window of implantation, and impaired apicobasal transformation that prevents …

Digital Technology Needs In Maternal Mental Health: A Qualitative Inquiry., Alexandra Zingg, Laura Carter, Deevakar Rogith, Amy Franklin, Sudhakar Selvaraj, Jerrie Refuerzo, Sahiti Myneni

Journal Articles

Digital technologies offer many opportunities to improve mental healthcare management for women seeking pre- and-postnatal care. They provide a discrete, practical medium that is well-suited for the sensitive nature of mental health. Women who are more prone to experiencing peripartum depression (PPD), such as those of low-socioeconomic background or in high-risk pregnancies, can benefit the most from such technologies. However, current digital interventions directed towards this population provide suboptimal support, and their responsiveness to end user needs is quite limited. Our objective is to understand the digital terrain of information needs for low-socioeconomic status women with high-risk pregnancies, specifically within …

Illuminating Health Disparities: The Untold Story Of Black Women’S Pregnancies, Kacy Workman

Osmosis Magazine

Recent studies have found that Black women are 3-4 times more likely to die from pregnancy-related complications than White women. Researchers in the 1990s examined data surrounding specific pregnancy complications such as postpartum hemorrhage, finding that although prevalence rates were similar between White and Black women, Black women with these conditions were 2-3 times more likely to die than their White counterparts. Despite medical advances, these rates have not improved over time. Data analyses examining maternal mortality from 2005 – 2014 reveal that mortality rates for Black women have actually increased from 39 to 49 deaths for every 100,000 live …

The Effects Of Maternal Delta-9-Tetrahydrocannabinol And Cannabidiol Exposure On Fetal Heart Development In Mice, Gregory Robinson

Electronic Thesis and Dissertation Repository

Up to 22.6% of pregnant women consume cannabis during pregnancy despite the uncertainty of teratogenicity of the main ingredients in cannabis, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). This study tested the hypothesis that gestational THC and CBD exposure leads to heart abnormalities. Daily, oral THC exposure induced heart abnormalities in 68% of offspring with three main phenotypes including thickened semilunar valves, ventricular myocardial hypertrophy and hypoplastic coronary arteries in fetuses, and postnatal cardiac dysfunction. Altered gene expression of key cardiogenic regulators, increased proliferation, and reduced epicardial epithelial-to-mesenchymal-transition were demonstrated implicating potential mechanisms responsible for these abnormalities. Also, maternal CBD exposure resulted …

Maternal Prenatal Cortisol Programs The Infant Hypothalamic–Pituitary–Adrenal Axis, Jessica L. Irwin, Amy L. Meyering, Gage Peterson, Laura M. Glynn, Curt A. Sandman, Laurel M. Hicks, Elysia Poggi Davis

Psychology Faculty Articles and Research

One of the key proposed agents of fetal programming is exposure to maternal glucocorticoids. Experimental animal studies provide evidence that prenatal exposure to elevated maternal glucocorticoids has consequences for hypothalamic–pituitary–adrenal (HPA) axis functioning in the offspring. There are very few direct tests of maternal glucocorticoids, such as cortisol, during human pregnancy and associations with infant cortisol reactivity. The current study examined the link between maternal prenatal cortisol trajectories and infant cortisol reactivity to the pain of inoculation in a sample of 152 mother-infant (47.4% girls) pairs. The results from the current study provide insight into fetal programming of the infant …

The Autoimmune System: The Effect Of Physiological Stressors On Autoantibody Glycosylation And Fidelity Of Autoantibody Profiles, Rahil Kheirkhah

Graduate School of Biomedical Sciences Theses and Dissertations

The presence of thousands of autoantibodies (aABs) in the human sera is typical, and therefore it is possible to identify an aAB profile for each individual. In the first part of this thesis, we will show the cerebrospinal fluid also exhibits an extraordinarily complex immunoglobulin G aAB profile that is composed of thousands of aABs. We show that the pattern of expression of individual aABs in CSF closely mimics that in the blood, indicative of a blood-based origin for CSF aABs. In addition, using longitudinal serum samples obtained over a span of nine years, we show remarkable stability in aAB …

Relation Of Flt-1 And Endothelial Function In Women Soon After Delivery: Effect Of Physical Activity And Sedentary Behavior, Chloe W. Caudell

Senior Theses

Adverse pregnancy outcomes (APOs) are believed to be caused by poor placental formation. APOs can be characterized by elevated levels of a circulating Fms-like tyrosine kinase biomarker called Flt-1, produced by the placenta when its blood vessels are shallow or inadequately formed. Flt-1 acts directly on the maternal endothelium to impair vascular function during pregnancy and contributes to maternal features of APOs. This study aimed to evaluate the relation of Flt-1 and endothelial function in women soon after delivery. This study also aimed to evaluate the relation of Flt-1 and physical activity and sedentary behavior in women during and soon …

Oocyte Recovery And In Vitro Embryo Production In Cows Treated With A Single Dose Offollicle-Stimulating Hormone, Thiago Marquez Fernandes, Paulo Roberto Adona, Samuel Guemra, Tiago Henrique Camara De Bem, Moyses Dos Santos Miranda

Turkish Journal of Veterinary & Animal Sciences

Cows were treated with follicle-stimulating hormone (FSH) in a single dose and then subjected to ovum pick-up (OPU) for evaluation of oocyte recovery and in vitro fertilization (IVF). Cows underwent OPU followed by application of FSH (200 mg) on day 2 and new OPU on day 3. This methodology was repeated 3 times sequentially. In FSH-free the cows (control), OPU was performed at intervals of one week. The number of oocytes recovered was higher in the control cows (22.2 ± 1.5) compared to the treated cows (16.9 ± 1.4; P < 0.05). There was no difference between the control (13.2 ± 0.6) and the treated (11.2 ± 1.1) cows in the number of viable oocytes (P > 0.05). There was no difference between the control cows (47.1 …
