Intimate Partner Violence After Disclosure Of Hiv Test Results Among Pregnant Women In Harare, Zimbabwe, Simukai Shamu, Christina Zarowsky, Tamara Shefer, Marleen Temmerman, Naeemah Abrahams

Obstetrics and Gynaecology, East Africa

Background: HIV status disclosure is a central strategy in HIV prevention and treatment but in high prevalence settings women test disproportionately and most often during pregnancy. This study reports intimate partner violence (IPV) following disclosure of HIV test results by pregnant women.

Methods: In this cross sectional study we interviewed 1951 postnatal women who tested positive and negative for HIV about IPV experiences following HIV test disclosure, using an adapted WHO questionnaire. Multivariate regression models assessed factors associated with IPV after disclosure and controlled for factors such as previous IPV and other known behavioural factors associated with IPV.

Results: Over …

The hypothalamic kisspeptin signaling system is a major positive regulator of the reproductive neuroendocrine axis, and loss of Kiss1 in the mouse results in infertility, a condition generally attributed to its hypogonadotropic hypogonadism. We demonstrate that in Kiss1(-/-) female mice, acute replacement of gonadotropins and estradiol restores ovulation, mating, and fertilization; however, these mice are still unable to achieve pregnancy because embryos fail to implant. Progesterone treatment did not overcome this defect. Kiss1(+/-) embryos transferred to a wild-type female mouse can successfully implant, demonstrating the defect is due to maternal factors. Kisspeptin and its receptor are expressed in the mouse …

Pregnancy Anxiety And Prenatal Cortisol Trajectories, Heidi S. Kane, Christine Dunkel Schetter, Laura M. Glynn, Calvin J. Hobel, Curt A. Sandman

Psychology Faculty Articles and Research

Pregnancy anxiety is a potent predictor of adverse birth and infant outcomes. The goal of the current study was to examine one potential mechanism whereby these effects may occur by testing associations between pregnancy anxiety and maternal salivary cortisol on 4 occasions during pregnancy in a sample of 448 women. Higher mean levels of pregnancy anxiety over the course of pregnancy predicted steeper increases in cortisol trajectories compared to lower pregnancy anxiety. Significant differences between cortisol trajectories emerged between 30 to 31 weeks of gestation. Results remained significant when adjusted for state anxiety and perceived stress. Neither changes in pregnancy …


Cancer Diagnosis During Pregnancy: Evaluating The Challenges Faced By Oncologists, Shannon Kaye Mulligan May 2014

Cancer Diagnosis During Pregnancy: Evaluating The Challenges Faced By Oncologists, Shannon Kaye Mulligan

Dissertations and Theses (Open Access)

Cancer during pregnancy is occurring more often than in the past, and it is estimated that cancer is diagnosed in approximately 1/1000 pregnancies. A consensus exists that management of these patients should prioritize survival of the mother and minimize teratogenic effects to the fetus, and utilize a multidisciplinary approach, involving medical oncology, surgical oncology, radiation oncology, radiology, and a maternal fetal medicine specialist. In spite of this consensus, there is not a standardized approach for treating cancer in women diagnosed during pregnancy. Due to the relative infrequency of this situation in the oncologic setting, the aims of this study were …


Why 'Down Under' Is A Cut Above: A Comparison Of Rates Of And Reasons For Caesarean Section In England And Australia, Samantha J. Prosser, Yvette D. Miller, Rachel Thompson, Maggie Redshaw Apr 2014

Why 'Down Under' Is A Cut Above: A Comparison Of Rates Of And Reasons For Caesarean Section In England And Australia, Samantha J. Prosser, Yvette D. Miller, Rachel Thompson, Maggie Redshaw

Dartmouth Scholarship

Background: Most studies examining determinants of rising rates of caesarean section have examined patterns in documented reasons for caesarean over time in a single location. Further insights could be gleaned from cross-cultural research that examines practice patterns in locations with disparate rates of caesarean section at a single time point.

Methods: We compared both rates of and main reason for pre-labour and intrapartum caesarean between England and Queensland, Australia, using data from retrospective cross-sectional surveys of women who had recently given birth in England (n = 5,250) and Queensland (n = 3,467).

Jablonski, Jose C Florez, Dana Dabelea, Paul W Franks, Sam Dagogo-Jack, Catherine Kim, William C Knowler, Costas A Christophi, Robert Ratner, Diabetes Prevention Program Research Group.

GW Biostatistics Center

OBJECTIVE The Diabetes Prevention Program (DPP) trial investigated rates of progression to diabetes among adults with prediabetes randomized to treatment with placebo, metformin, or intensive lifestyle intervention. Among women in the DPP, diabetes risk reduction with metformin was greater in women with prior gestational diabetes mellitus (GDM) compared with women without GDM but with one or more previous live births.

RESEARCH DESIGN AND METHODS We asked if genetic variability could account for these differences by comparing β-cell function and genetic risk scores (GRS), calculated from 34 diabetes-associated loci, between women with and without histories of GDM.

RESULTS β-Cell function was …

The Texas Heart Institute Journal

Acute pulmonary embolism is a leading cause of death during pregnancy and delivery in the United States. We describe the case of a 25-year-old woman who presented in cardiogenic shock in week 38 of her first pregnancy. After the emergent cesarean delivery of a healthy male neonate, the mother underwent immediate surgical pulmonary embolectomy. We confirmed the diagnosis of pulmonary embolism intraoperatively by means of transesophageal echocardiography and removed large clots from the patient's pulmonary arteries. Mother and child were doing well, 27 months later. In addition to presenting our patient's case, we discuss the other relevant reports and the …

Maternal Biomarkers Of Endothelial Dysfunction And Preterm Delivery, Xinhua Chen, Theresa O Scholl

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Endothelial dysfunction is key to the development of atherosclerosis. Preterm delivery foreshadows later maternal cardiovascular disease (CVD), but it is not known if endothelial dysfunction also occurs. We prospectively measured circulating biomarkers of endothelial dysfunction in pregnant women with preterm or term delivery.

METHODS: We conducted a case-control study nested within a large prospective epidemiological study of young, generally healthy pregnant women. Women who delivered preterm (gestation, n = 240) and controls who delivered at term (n = 439) were included. Pregnancies complicated by preeclampsia were analyzed separately. Circulating endothelial dysfunction biomarkers included soluble intercellular adhesion molecule-1 (sICAM-1), vascular …

Helping The Community From The Bottom Up: Distributing Diapers To The Williamsburg Community, Constance A. Hull, Caroline Kelsey Jan 2014

Helping The Community From The Bottom Up: Distributing Diapers To The Williamsburg Community, Constance A. Hull, Caroline Kelsey

VA Engage Journal

There is a great need for a sustainable supply of clean diapers for low-income residents of Williamsburg since this region is without a diaper bank. Being unable to afford diapers can have a myriad of negative consequences from being unable to send children to child care to increased health risks involved in leaving a baby in a soiled diaper. Our model of a diaper bank differs from most because we mail diapers directly to families, eliminating transportation needs. We hope to partner with community agencies and The College of William & Mary to expand our services and create a more …

Low Birth Weight Male Guinea Pig Offspring Display Increased Visceral Adiposity In Early Adulthood., Ousseynou Sarr, Jennifer A Thompson, Lin Zhao, Ting-Yim Lee, Timothy Regnault

Paediatrics Publications

Uteroplacental insufficiency (UPI)-induced intrauterine growth restriction (IUGR) predisposes individuals to adult visceral obesity. We postulated that low birth weight (LBW) offspring, from UPI-induced IUGR pregnancies, would display a visceral adipose lipogenic molecular signature involving altered gene expression, phosphorylation status of proteins of the lipid synthesis pathway and microRNA (miR) expression profile, occurring in association with increased visceral adiposity. Normal birth weight (NBW) and LBW (obtained by uterine artery ablation) male guinea pig pups were fed a control diet from weaning to 145 days and sacrificed. Despite being lighter at birth, LBW pups displayed body weights similar to NBW offspring at …


Menarche, Stephanie Stockburger, Hatim A. Omar Jan 2014

Menarche, Stephanie Stockburger, Hatim A. Omar

Pediatrics Faculty Publications

Menarche is a female’s first menstrual period and a landmark event for females during puberty. Historically, menarche has been thought of as a time when women were “unclean.” However, cultural acceptance and scientific knowledge of menarche has greatly increased. Menarche occurs as part of the typical progression of puberty caused by rises in luteinizing hormone (LH), follicle stimulating hormone (FSH), and estrogen. The achievement of menstruation is associated with reproductive capability. Menarche that occurs earlier or later than expected should be evaluated by an experienced clinician and may signal a serious underlying problem. Currently, researchers are evaluating whether menarche is …

Cervical Remodeling/Ripening At Term And Preterm Delivery: The Same Mechanism Initiated By Different Mediators And Different Effector Cells, Juan Miguel Gonzalez Velez

Wayne State University Dissertations

Premature cervical remodeling/ripening is believed to contribute to preterm delivery (PTD), the leading cause of perinatal morbidity and mortality. Despite considerable research, the causes of term and PTD remain unclear, and there is no effective treatment for PTD. We tested the hypothesis that complement activation plays a role in cervical remodeling and PTD. We studied cervical remodeling at term.

We studied two mouse models of inflammation-induced PTD. The first model was induced by vaginal administration of lipopolysaccharide (LPS)and the second one by administration of progesterone antagonist RU486. Increased cervical C3 deposition and macrophage infiltration and increased serum C3adesArg and C5adesArg …

Maternal Anaemia And Duration Of Zidovudine In Antiretroviral Regimens For Preventing Mother-To-Child Transmission: A Randomized Trial In Three African Countries, Benn K.D. Sartorius, Matthew F. Chersich, Mary Mwaura, Nicolas Meda, Marleen Temmerman, Marie Louise Newell, Timothy M. M. Farley, Stanley Luchters, The Kesho Bora Study Group

Obstetrics and Gynaecology, East Africa

Background: Although substantiated by little evidence, concerns about zidovudine-related anaemia in pregnancy have influenced antiretroviral (ARV) regimen choice for preventing mother-to-child transmission of HIV-1, especially in settings where anaemia is common.

Methods: Eligible HIV-infected pregnant women in Burkina Faso, Kenya and South Africa were followed from 28 weeks of pregnancy until 12–24 months after delivery (n = 1070). Women with a CD4 count of 200-500cells/mm3 and gestational age 28–36 weeks were randomly assigned to zidovudine-containing triple-ARV prophylaxis continued during breastfeeding up to 6-months, or to zidovudine during pregnancy plus single-dose nevirapine (sd-NVP) at labour. Additionally, two cohorts were …

Wilson’S Disease In Pregnancy: Case Series And Review Of Literature, Ayesha Malik, Ali Khawaja, Lumaan Sheikh

Department of Obstetrics & Gynaecology

Background: Wilson’s disease is a rare, autosomal recessive inherited disorder characterized by impaired liver metabolism of copper leading to decreased biliary excretion and incorporation of ceruloplasmin levels mainly in the liver and brain. Untreated Wilson’s disease has been shown to cause subfertility and even in cases where pregnancy occurs, it often results in spontaneous miscarriage.

Case presentations: We present four cases of successful pregnancy outcomes in three patients diagnosed with Wilson’s disease along with the literature review. All the patients were managed with zinc sulphate without any postnatal complications.

Conclusion: Patients with Wilson’s disease receiving regular treatment who remain asymptomatic …

Obstetrics & Gynaecology Publications

Stress-inducible phosphoprotein 1 (STI1) is part of the chaperone machinery, but it also functions as an extracellular ligand for the prion protein. However, the physiological relevance of these STI1 activities in vivo is unknown. Here, we show that in the absence of embryonic STI1, several Hsp90 client proteins are decreased by 50%, although Hsp90 levels are unaffected. Mutant STI1 mice showed increased caspase-3 activation and 50% impairment in cellular proliferation. Moreover, placental disruption and lack of cellular viability were linked to embryonic death by E10.5 in STI1-mutant mice. Rescue of embryonic lethality in these mutants, by transgenic expression of the …


Association Between Elevated Third Trimester Maternal Haemoglobin And Neonatal Gestational Age Adjusted Birth Weight, Bob Otieno Achila Sep 2013

Association Between Elevated Third Trimester Maternal Haemoglobin And Neonatal Gestational Age Adjusted Birth Weight, Bob Otieno Achila

Master of Medicine in Obstetrics and Gynecology

Background: Women tend to have lower haemoglobin compared to men due to menstrual blood losses. This is often compounded by nutritional deficiencies. There is a further drop in haemoglobin during pregnancy due to red cell dilution. Pregnancy itself places a huge demand on maternal iron stores. High haemoglobin may reflect haemoconcentration due to a failure of the normal physiological expansion in plasma volume. Iron excess has also been associated with free-radical damage. In current practice, high maternal haemoglobin in pregnancy is often not given as much attention as anaemia. This study examines the association between high maternal haemoglobin in the …

Biomarkers Of Maternal And Fetal Exposure To Organochlorine Pesticides Measured In Pregnant Hispanic Women From Brownsville, Texas, Ken Sexton, Jennifer J Salinas, Thomas J Mcdonald, Rose M Z Gowen, Rebecca P Miller, Joseph B Mccormick, Susan P Fisher-Hoch

Faculty, Staff and Student Publications

Biomarkers of organochlorine pesticides were measured in both venous and umbilical cord blood from 35 pregnant Hispanic women living in Brownsville, Texas, USA. Gas chromatography with an electron capture detector was used to analyze specimens for 30 individual pesticides or their metabolites. Results indicate that blood concentrations were relatively low for most individual compounds, but that high-end (upper 10th percentile) values for total DDT were comparatively high. Although health effects associated with measured blood concentrations are uncertain, there is concern that fetal exposure to low levels of these OC compounds, either individually or in combination, might contribute to subsequent health …


P38 Mapk Regulates Cavitation And Tight Junction Function In The Mouse Blastocyst., Christine E Bell, Andrew J Watson Jan 2013

P38 Mapk Regulates Cavitation And Tight Junction Function In The Mouse Blastocyst., Christine E Bell, Andrew J Watson

Obstetrics & Gynaecology Publications

UNLABELLED: Blastocyst formation is essential for implantation and maintenance of pregnancy and is dependent on the expression and coordinated function of a series of proteins involved in establishing and maintaining the trans-trophectoderm ion gradient that enables blastocyst expansion. These consist of Na/K-ATPase, adherens junctions, tight junctions (TJ) and aquaporins (AQP). While their role in supporting blastocyst formation is established, the intracellular signaling pathways that coordinate their function is unclear. The p38 MAPK pathway plays a role in regulating these proteins in other cell types and is required for embryo development at the 8-16 cell stage, but its role has not …


Prevalence Of Vitamin D Deficiency In An Ethnic African Urban Obstetric Population In An Equatorial City Hospital, Raj Hasmukh Dodia Jan 2013

Prevalence Of Vitamin D Deficiency In An Ethnic African Urban Obstetric Population In An Equatorial City Hospital, Raj Hasmukh Dodia

Master of Medicine in Obstetrics and Gynecology

Introduction: Low Vitamin D levels in pregnancy have been associated with an increased risk of gestational diabetes, pre-eclampsia, bacterial vaginosis, preterm birth, disordered fetal skeletal homeostasis, and impaired offspring lung health. As a result, current public health advice in several countries is to universally supplement Vitamin D during pregnancy. Data regarding the Vitamin D levels of the ethnic obstetric population in Kenya are not available; hence recommendations for Vitamin D supplementation have no scientific basis. Objectives of study: This research was carried out to determine the prevalence of deficiency of Vitamin D in ethnic African obstetric patients who had delivered …
