Dyshomeostasis of vitamin D-binding protein (VDBP) has been implicated in the patho-genesis of various pregnancy complications, including preeclampsia, preterm birth, gestational di-abetes, and adverse metabolic profiles in the offspring. VDBP polymorphisms have been consistently reported to contribute to this intriguing interplay. Until recently, the effects of VDBP poly-morphism heterogeneity on maternal and neonatal adipomyokine profiles have not been investi-gated, specifically after incorporating the different maternal and neonatal 25-hydroxyvitamin D concentration cut-offs at birth. We aimed to investigate the potential effects of maternal and neonatal VDBP polymorphisms on adiponectin, irisin, and VDBP concentrations at birth, according to different cut-offs of vitamin …

Exposure to tobacco smoke during pregnancy has been associated with a series of adverse reproductive outcomes; however, the underlying molecular mechanisms are not well-established. We conducted an untargeted metabolome-wide association study to identify the metabolic perturbations and molecular mechanisms underlying the association between cotinine, a widely used biomarker of tobacco exposure, and adverse birth outcomes. We collected early and late pregnancy urine samples for cotinine measurement and serum samples for high-resolution metabolomics (HRM) profiling from 105 pregnant women from the Atlanta African American Maternal-Child cohort (2014-2016). Maternal metabolome perturbations mediating prenatal tobacco smoke exposure and adverse birth outcomes were assessed …

Low- And High-Wattage Vaping During Pregnancy Influence Aortic Structure And Function In Rat Offspring, James Ian Frazier

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Electronic cigarettes (e-cigs) are being marketed as a healthier alternative to traditional cigarettes, yet the health consequences of e-cig usage (also called vaping) are still being investigated. E-cigs are easily customized for user preferences. For example, the choice of flavors, nicotine concentration, and/or the temperature (i.e., wattage) used to heat the e-liquid can be selected in many devices. Emerging evidence suggests that vaping during pregnancy impairs cerebral vascular function in rodent offspring. In this study, we sought to investigate the potential effects of changes to e-cig device wattage (i.e., 5W vs. 30W) with maternal vaping during pregnancy on vascular …

Vaping During Pregnancy: Effects On Vascular And Behavioral Outcomes In Offspring, Eiman A. Aboaziza

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electronic cigarette (e-cig) use is increasing due to aggressive marketing, tempting flavors, and seemingly higher acceptability in the community (lesser perceived social stigma) despite unproven claims of safety. In an alarming trend, pregnant women smokers have turned to novel “modified risk” products, such as e-cigs, in response to heavy marketing of e-cigs as safer alternatives to cigarettes and a tool to help quit smoking. This is despite proven detrimental effects of nicotine on a growing fetus, and scarcity of information regarding toxicity of e-liquid (with and without nicotine) on child development. Moreover, rampant e-cig use among youth (nearly 4 million …

A Novel Model Of Gestational Diabetes: Acute High Fat High Sugar Diet Results In Insulin Resistance And Beta Cell Dysfunction During Pregnancy In Mice, Akansha Mishra, Simone Hernandez Ruano, Pradip K Saha, Kathleen A Pennington

Faculty, Staff and Students Publications

Gestational diabetes mellitus (GDM) affects 7–18% of all pregnancies. Despite its high prevalence, there is no widely accepted animal model. To address this, we recently developed a mouse model of GDM. The goal of this work was to further characterize this animal model by assessing insulin resistance and beta cell function. Mice were randomly assigned to either control (CD) or high fat, high sugar (HFHS) diet and mated 1 week later. At day 0 (day of mating) mice were fasted and intraperitoneal insulin tolerance tests (ipITT) were performed. Mice were then euthanized and pancreata were collected for histological analysis.

BACKGROUND: Despite high rates of HIV testing and enrolment of HIV-positive pregnant women on antiretroviral therapy in Botswana, coverage for HIV-exposed infant (HEI) testing remains suboptimal. Many factors can contribute to suboptimal HEI testing rates, but they have seldom been thoroughly investigated in Botswana. Therefore, the aim of this study was to explore the experiences and perspectives of HIV-positive mothers on the barriers and facilitators of HEI testing to inform interventions to promote HEI testing in Botswana.

METHODS: We conducted focus group discussions (FGDs) with HIV-positive mothers who gave birth in 2016 at the three largest public hospitals in Botswana. …

Nuclear Progesterone Receptor Expressed By The Cortical Thymic Epithelial Cells Dictates Thymus Involution In Murine Pregnancy, Soo Hyun Ahn, Sean L Nguyen, Tae Hoon Kim, Jae-Wook Jeong, Ripla Arora, John P Lydon, Margaret G Petroff

Faculty, Staff and Students Publications

Progesterone is a gonadal pro-gestational hormone that is absolutely necessary for the success of pregnancy. Most notable actions of progesterone are observed in the female reproductive organs, the uterus and the ovary. Acting through the nuclear progesterone receptor (PGR), progesterone prepares the endometrium for implantation of the embryo. Interestingly, the maternal thymus also is a known expressor of Pgr; its absence is associated with murine pregnancy complications. However, the localization of its expression and its functional importance were not known. Here, we used a transgenic dual fluorescent reporter mouse model and genetic deletion of Pgr in Foxn1+ thymic epithelial …

Faculty, Staff and Students Publications

Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy but the underlying mechanism remains obscure. The aims of this study are to examine if omental adipose tissue (OMAT) and subcutaneous AT (SCAT) differentially express proinflammatory and lipid metabolic adipokines, and if so, whether their regional differences have implications on lipid metabolism in GDM. Paired samples of OMAT and SCAT were excised from pregnant women in scheduled Cesarean sections with non-obese (NOBS), obese (OBS) and GDM. The results showed that the mRNA of monocyte chemoattractant protein (MCP)-1, macrophage marker CD68, and cytokines IL-6, IL-8, and TNF-α are …

In this study, we examine the expression of soluble Fms-like tyrosine kinase 1 (sFLT-1) and placental growth factor (PlGF), which is one of the vascular endothelial growth factors (VEGFs), as these play a key role in angiogenesis; in particular, we examine their effect on the sFLT-1/PlGF ratio in cases of preterm birth as compared to typical pregnancies. Enzyme-linked immunosorbent assay was performed on samples of maternal-derived plasma and extracellular vesicles-exosomes (EVs-EXs) isolated at the third trimester, consisting of 17 samples from cases …

Epidural Anesthesia For Cesarean Section For Parturient With Recently Diagnosed Asymptomatic Chiari Malformation Type I: A Case Report, Ashie Kapoor, Jon Halling

HCA Healthcare Journal of Medicine

Chiari malformations (CMs) are congenital defects of the brain and skull that result in inferior displacement of the cerebellum. There are four types of CMs distinguished by the severity of the anatomic defects and parts of the brain that protrude beyond the foramen magnum. Of these types, CM Type I (CMI) is the least severe. It is characterized by the downward displacement of the cerebellar tonsils beyond the foramen magnum by more than 5 millimeters and goes into the cervical spinal canal. CMI is the most common type with an incidence of 0.1-0.5% in the general population and a predominance …

Glad To Be Out. I Was Running Out Of Womb: A Study Of Omega-6 And Omega-3 Fatty Acid Metabolites At Delivery And Their Relationship To Infant Growth, Prematurity, And Admission To The Neonatal Intensive Care Unit, Maranda Thompson

Theses & Dissertations

Normal pregnancy relies on inflammation for implantation, placentation, and parturition, but uncontrolled it can lead to poor infant outcomes. Maternal diet is one modifiable factor that can impact inflammation. Omega-3 and omega-6 fatty acids have been shown to be metabolized into bioactive metabolites that effect inflammation. The presence and importance of these metabolites at the time of delivery are not well understood. Therefore, the purpose of this dissertation was to first quantify omega-3 and omega-6 metabolites in maternal plasma, cord plasma, and placental tissue. Then the relationships between metabolites and infant outcomes, including birth weight percentile, length percentile, head circumferences …

Children’s Nutrition Research Center Staff Publications

Optimizing enteral nutrition for premature infants may help mitigate extrauterine growth restriction and adverse chronic health outcomes. Previously, we showed in neonatal pigs born at term that lean growth is enhanced by intermittent bolus compared with continuous feeding. The objective was to determine if prematurity impacts how body composition, muscle protein synthesis, and myonuclear accretion respond to feeding modality. Following preterm delivery, pigs were fed equivalent amounts of formula delivered either as intermittent boluses (INT; n = 30) or continuously (CONT; n = 14) for 21 days. Body composition was measured by dual-energy X-ray absorptiometry (DXA) and muscle growth was …

Maxwell H. Gluck Equine Research Center Faculty Publications

A sufficient vascular network within the feto-maternal interface is necessary for placental function. Several pregnancy abnormalities have been associated with abnormal vascular formations in the placenta. We hypothesized that growth and expansion of the placental vascular network in the equine (Equus caballus) placenta is regulated by estrogens (estrogen family hormones), a hormone with a high circulating concentration during equine gestation. Administration of letrozole, a potent and specific inhibitor of aromatase, during the first trimester (D30 to D118), decreased circulatory estrone sulfate concentrations, increased circulatory testosterone and androstenedione concentrations, and tended to reduce the weight of the fetus ( …
