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 …

Department of Obstetrics and Gynecology Faculty Papers

OBJECTIVE: To report the first successful full-term delivery following Per Oral Endoscopic Myotomy (POEM) performed during pregnancy.

METHODS/BACKGROUND: Achalasia is an esophageal motility disorder characterized by dysphagia, regurgitation, reflux, recurrent vomiting, and weight loss. Achalasia in pregnancy can affect nutritional status of the mother, and subsequently, the child, increasing morbidity and creating potential pregnancy complications. POEM is a novel endoscopic procedure which involves cutting the lower esophageal sphincter to allow food to pass, and is considered a safe and effective management option for achalasia in non-pregnant individuals.

RESULTS: We discuss the case of a patient with achalasia and a prior …

Faculty, Staff and Students Publications

Importance: In the 1930s, the government-sponsored Home Owners' Loan Corporation (HOLC) established maps of US neighborhoods that identified mortgage risk (grade A [green] characterizing lowest-risk neighborhoods in the US through mechanisms that transcend traditional risk factors to grade D [red] characterizing highest risk). This practice led to disinvestments and segregation in neighborhoods considered redlined. Very few studies have targeted whether there is an association between redlining and cardiovascular disease.

Objective: To evaluate whether redlining is associated with adverse cardiovascular outcomes in US veterans.

Design, setting, and participants: In this longitudinal cohort study, US veterans were followed up (January 1, 2016, …

Invited Review: Adrenocortical Function In Avian And Non-Avian Reptiles: Insights From Dispersed Adrenocortical Cells., Rocco V. Carsia, Patrick J. Mcilroy, Henry B John-Alder

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Herein we review our work involving dispersed adrenocortical cells from several lizard species: the Eastern Fence Lizard (Sceloporus undulatus), Yarrow's Spiny Lizard (Sceloporus jarrovii), Striped Plateau Lizard (Sceloporus virgatus) and the Yucatán Banded Gecko (Coleonyx elegans). Early work demonstrated changes in steroidogenic function of adrenocortical cells derived from adult S. undulatus associated with seasonal interactions with sex. However, new information suggests that both sexes operate within the same steroidogenic budget over season. The observed sex effect was further explored in orchiectomized and ovariectomized lizards, some supported with exogenous testosterone. Overall, a suppressive effect of testosterone was evident, especially in cells …

Sex-Based Differences In The Presentation And Outcomes Of Acute Pulmonary Embolism: A Systematic Review And Meta-Analysis, Yu Zhang, Yu Qiu, Jinming Luo, Jian Zhang, Qingqing Yan

The Texas Heart Institute Journal

BACKGROUND: The study aimed to review differences in the presentation and outcomes of acute pulmonary embolism (PE) between men and women.

METHODS: PubMed, CENTRAL, Web of Science, and Embase were searched for studies comparing clinical features or outcomes of PE between men and women. Baseline comorbidities, risk factors, clinical features, and mortality rates were also compared between men and women.

RESULTS: Fourteen studies were included. It was noted that men presented with PE at a statistically significantly younger age than women (P < .001). Smoking history (P < .001), lung disease (P = .004), malignancy (P = .02), and unprovoked PE (P = .004) were significantly more frequent among men than among women. There was no difference between the sexes for hypertension, diabetes, and a history of recent immobilization. A significantly higher proportion of men presented with chest pain (P = .02) and hemoptysis (P < .001), whereas syncope (P = .005) was more frequent in women. Compared with men, women had a higher proportion of high-risk PE (P = .003). There was no difference in the use of thrombolytic therapy or inferior vena cava filter. Neither crude nor adjusted mortality rates were significantly different between men and women.

CONCLUSION: This review found that the age at presentation, comorbidities, and symptoms of PE differed between men and …

High mortality rates in ovarian cancer have been linked to recurrence, metastasis, and chemoresistant disease, which are known to involve not only genetic changes but also epigenetic aberrations. In ovarian cancer, adipose-derived stem cells from the omentum (O-ASCs) play a crucial role in supporting the tumor and its tumorigenic microenvironment, further propagating epigenetic abnormalities and dissemination of the disease. Epigallocatechin gallate (EGCG), a DNA methyltransferase inhibitor derived from green tea, and Indole-3-carbinol (I3C), a histone deacetylase inhibitor from cruciferous vegetables, carry promising effects in reprograming aberrant epigenetic modifications in cancer. Therefore, we demonstrate the action of these diet-derived compounds in …

Prematurity Blunts Protein Synthesis In Skeletal Muscle Independently Of Body Weight In Neonatal Pigs, Marko Rudar, Jane K Naberhuis, Agus Suryawan, Hanh V Nguyen, Marta L Fiorotto, Teresa A Davis

Faculty, Staff and Students Publications

Background

Postnatal growth failure in premature infants is associated with reduced lean mass accretion. Prematurity impairs the feeding-induced stimulation of translation initiation and protein synthesis in the skeletal muscle of neonatal pigs. The objective was to determine whether body weight independently contributes to the blunted postprandial protein synthesis.

Methods

Preterm and term pigs that were either fasted or fed were stratified into quartiles according to birth weight to yield preterm and term groups of similar body weight; first and second quartiles of preterm pigs and third and fourth quartiles of term pigs were compared (preterm-fasted, n = 23; preterm-fed, n …

Faculty, Staff and Students Publications

Military sexual trauma (MST) has deleterious long-term psychological consequences. Among female U.S. military members, MST is associated with increased risk for future interpersonal victimization, such as experiencing intimate partner violence (IPV). Few studies have investigated the implications of the cumulative effects of IPV and MST on psychological functioning. This study examined rates of co-exposure to MST, IPV, and their cumulative impact on psychological symptoms. Data were collected from 308 female Veterans (FVets; age:
