Implantation Failure In Female Kiss1-/- Mice Is Independent Of Their Hypogonadic State And Can Be Partially Rescued By Leukemia Inhibitory Factor., Michele Calder, Yee-Ming Chan, Renju Raj, Macarena Pampillo, Adrienne Elbert, Michelle Noonan, Carolina Gillio-Meina, Claudia Caligioni, Nathalie G Bérubé, Moshmi Bhattacharya, Andrew J Watson, Stephanie B Seminara, Andy V Babwah

Obstetrics & Gynaecology Publications

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

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

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).

Complementary And Alternative Medicine Use In Women During Pregnancy: Do Their Healthcare Providers Know?, Lisa Strouss, Amy Mackley, Ursula Guillen, David A Paul, Robert Locke

Student Papers, Posters & Projects

BACKGROUND: The National Institutes of Health reported in 2007 that approximately 38% of United States adults have used at least one type of Complementary and Alternative Medicine (CAM). There are no studies available that assess general CAM use in US pregnant women.The objectives of our study were to determine the prevalence and type of CAM use during pregnancy at one medical center; understand who is using CAM and why they are using it; and assess the state of patients' CAM use disclosure to their obstetrical providers.

METHODS: A cross-sectional survey study of post-partum women was done to assess self-reported CAM …

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 …

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 …

This study in Benghazi compared the rates of preterm, low-birth-weight and caesarean-section births at Al-Jamhouria hospital in the months before and during the armed conflict in Libya in 2011. Data were collected on all women admitted to the delivery ward during February to May 2011 (the months of the most active fighting in the city) (n = 7096), and October to December 2010 (the months immediately before the war) (n = 5935). Compared with the preceding months there was a significant rise during the conflict in the …

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 …

Stress-Inducible Phosphoprotein 1 Has Unique Cochaperone Activity During Development And Regulates Cellular Response To Ischemia Via The Prion Protein., Flavio H Beraldo, Iaci N Soares, Daniela F Goncalves, Jue Fan, Anu A Thomas, Tiago G Santos, Amro H Mohammad, Martin Roffé, Michele D Calder, Simona Nikolova, Glaucia N Hajj, Andre L Guimaraes, Andre R Massensini, Ian Welch, Dean H Betts, Robert Gros, Maria Drangova, Andrew J Watson, Robert Bartha, Vania F Prado, Vilma R Martins, Marco A M Prado

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

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 …

A Discursive Analysis Of A Pregnancy Center: How Pregnant Women Are Encouraged To Develop A Sense Of Self-Worth And Emotional Wellbeing Through The Use Of Rhetoric And Imagery, Jessica Postma

Masters Theses

This study presents and alternative approach to how pregnancy is interpreted in western society and how settings such as a pregnancy center both challenges and reinforces these social standards. The promotion of abstinence, the aversion to abortion, notions of truth and morality, religious narratives, and the standard of care are all integral components to this analysis of pregnancy, language, and culture.

Sickle Cell Disease In Pregnancy: Trend And Pregnancy Outcomes At A Tertiary Hospital In Tanzania, Projestine S. Muganyizi, Hussein Kidanto

Faculty of Health Sciences, East Africa

SCD in pregnancy is associated with increased adverse fetal and maternal outcomes. In Tanzania where the frequency of sickle cell trait is 13% there has been scanty data on SCD in pregnancy. With progressive improvement in childhood survival the burden of SCD in pregnancy will increase. We analyzed all deliveries at Muhimbili National Hospital (MNH) from 1999 to 2011. Fetal and maternal outcomes of SCD deliveries were compared with non-SCD. Data were analyzed using IBM SPSS statistics version 19. Chi square and Fisher Exact tests were used to compare proportions and the independent t-test for continuous data. To predict risks …

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

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 …

Background: We assessed the safety of Cabergoline therapy during pregnancy in a lady with hyperprolactinemia intolerant to Bromocriptine.

Case presentation: We report the case of a 31 year old lady who presented to us with uncontrolled hyperprolactinemia. A pituitary Macroadenoma was demonstrated by MRI. Due to intolerance to Bromocriptine, Cabergoline was started. The patient improved and subsequently conceived. MRI in the second trimester demonstrated further reduction in the tumor size. It was decided to continue Cabergoline throughout pregnancy to ensure further reduction in tumor size until delivery and to hold Cabergoline during postpartum period to allow for an adequate interval …

The Study Of Hiv And Antenatal Care Integration In Pregnancy In Kenya: Design, Methods, And Baseline Results Of A Cluster-Randomized Controlled Trial, Janet M. Turan, Rachel L. Steinfeld, Maricianah Onono, Elizabeth A. Bukusi, Meghan Woods, Starley B. Shade, Sierra Washington, Reson Marima, Jeremy Penner, Marta L. Ackers, Dorothy Mbori-Ngacha, Craig R. Cohen

Pathology, East Africa

Background: Despite strong evidence for the effectiveness of anti-retroviral therapy for improving the health of women living with HIV and for the prevention of mother-to-child transmission (PMTCT), HIV persists as a major maternal and child health problem in sub-Saharan Africa. In most settings antenatal care (ANC) services and HIV treatment services are offered in separate clinics. Integrating these services may result in better uptake of services, reduction of the time to treatment initiation, better adherence, and reduction of stigma.

Methodology/Principal Findings: A prospective cluster randomized controlled trial design was used to evaluate the effects of integrating HIV treatment into ANC …

Common Respiratory Issues In Ambulatory Obstetrics., Kelly M Orzechowski, Richard C Miller

Department of Obstetrics and Gynecology Faculty Papers

This article reviews the diagnosis and management of the most common respiratory conditions complicating pregnancy--asthma and influenza. We also review strategies for smoking cessation in pregnancy as, in addition to exacerbating all other pulmonary conditions, smoking is the most modifiable risk factor for poor pregnancy outcome. Moreover, the obstetrician frequently encounters each of these conditions in the ambulatory setting. A thorough knowledge of the normal pregnancy-induced physiological respiratory changes combined with a comprehensive understanding of how to manage these conditions, will provide the obstetrician with the armamentarium needed to optimize health outcomes for mothers and their fetuses.

The Ethics Of Vaginal Birth After Cesarean, Sonya Charles

Philosophy and Religious Studies Department Faculty Publications

The decline in providers and facilities that will allow a trial of labor after cesarean forces many women to choose a repeat cesarean. The choice is frequently not much of a choice, however, since the full range of options are often not on the table. This limited 'choice' violates obstetricians' obligations both to respect patients' autonomy and to offer them good care. There has been a vigorous but so far not very fruitful debate in the last few years about the lack of access to a trial of labor after cesarean. Some recently released documents express concern about the limited …

Progesterone And Preterm Birth Prevention: Translating Clinical Trials Data Into Clinical Practice, Vincenzo Berghella

Department of Obstetrics and Gynecology Faculty Papers

OBJECTIVE:

We sought to provide evidence-based guidelines for using progestogens for the prevention of preterm birth (PTB).

METHODS:

Relevant documents, in particular randomized trials, were identified using PubMed (US National Library of Medicine, 1983 through February 2012) publications, written in English, which evaluate the effectiveness of progestogens for prevention of PTB. Progestogens evaluated were, in particular, vaginal progesterone and 17-alpha-hydroxy-progesterone caproate. Additionally, the Cochrane Library, organizational guidelines, and studies identified through review of the above were utilized to identify relevant articles. Data were evaluated according to population studied, with separate analyses for singleton vs multiple gestations, prior PTB, or short …
