Obstetrics and Gynaecology, East Africa

Accurate estimation of gestational age is an essential component of good obstetric care and informs clinical decision-making throughout pregnancy. As the date of the last menstrual period is often unknown or uncertain, ultrasound measurement of fetal size is currently the best method for estimating gestational age. The calculation assumes an average fetal size at each gestational age. The method is accurate in the first trimester, but less so in the second and third trimesters as growth deviates from the average and variation in fetal size increases. Consequently, fetal ultrasound late in pregnancy has a wide margin of error of at …

Transabdominal Cerclage During Pregnancy: A Retrospective Single Operator Series Over A Quarter Century, David R Hall, Mari Van De Vyver

Faculty, Staff and Student Publications

OBJECTIVE: To describe the pregnancy outcomes and complications observed in a series of cases of transabdominal cerclage (TAC), which is reserved for highly selected women with recurrent mid-trimester pregnancy loss, due to cervical insufficiency.

METHODS: A retrospective audit covering 25 years (January 1, 1997 to December 31, 2021) was performed at the Obstetric Special Care division, Tygerberg Academic Hospital in Cape Town, South Africa. All 118 pregnancies from 94 procedures, operated and managed by the principal author were included for descriptive analysis.

RESULTS: Eighty-four (91.3%) of the 92 first pregnancies after first insertion had successful outcomes. All second and third …

Background: Premature birth is associated with an increased risk of mortality and morbidity, and strategies to prevent preterm birth are few in number and resource intensive. In 2020, the ASPIRIN trial showed the efficacy of low-dose aspirin (LDA) in nulliparous, singleton pregnancies for the prevention of preterm birth. We sought to investigate the cost-effectiveness of this therapy in low-income and middle-income countries.

Methods: In this post-hoc, prospective, cost-effectiveness study, we constructed a probabilistic decision tree model to compare the benefits and costs of LDA treatment compared with standard care using primary data and published results from the ASPIRIN trial. In …

Emerging evidence suggests that cryptic translation within long noncoding RNAs (lncRNAs) may produce novel proteins with important developmental/physiological functions. However, the role of this cryptic translation in complex diseases (e.g., cancer) remains elusive. Here, we applied an integrative strategy combining ribosome profiling and CRISPR/Cas9 screening with large-scale analysis of molecular/clinical data for breast cancer (BC) and identified estrogen receptor α-positive (ER+) BC dependency on the cryptic ORFs encoded by lncRNA genes that were upregulated in luminal tumors. We confirmed the in vivo tumor-promoting function of an unannotated protein, GATA3-interacting cryptic protein (GT3-INCP) encoded by LINC00992, the expression of which was …

Faculty, Staff and Students Publications

Background: Congenital anomalies of the kidney and urinary tract (CAKUTs) represent 15%–20% of prenatally diagnosed abnormalities. Maternal characteristics, the frequency of various forms of kidney disease including CAKUT referred for prenatal nephrology consultation, and their perinatal outcomes are less well defined.

Methods: A retrospective chart review was performed of fetal CAKUT and other forms of kidney disease referred for prenatal nephrology consults at Texas Children's Hospital Fetal Center from January 1, 2012, to December 31, 2018.

Results: Two hundred seventeen prenatal nephrology consultations were performed during the study period, representing 4.7% of total Fetal Center referrals at a mean estimated …

Juvenile-Type Granulosa Cell Tumor In Pregnancy Presenting As A Ruptured Abdominal Mass, Odinaka Mogor, Steven Feinstein, Glen Friedman, Jose Salvador Saldivar, Melissa Mendez

HCA Healthcare Journal of Medicine

Introduction

Granulosa cell tumors (GCTs) are part of the sex cord-stromal tumors occurring with a rare incidence rate that only makes up about 2-5% of all ovarian malignancies.

Case Presentation

A 28-year-old woman, gravida 2, para 1, presented with a juvenile-type granulosa cell tumor at 31 weeks gestation, which appeared as a rapidly growing mass with rupture. She underwent an exploratory laparotomy with unilateral salpingo-oophorectomy, and consequently had a successful vaginal delivery. Post-operatively she was treated with paclitaxel and carboplatin chemotherapy regimen with no evidence of recurrence after one year.

Conclusion

Radical surgical management is recommended for these tumors due …

The Presence Of A Single Nuchal Cord In The Third Trimester May Not Affect Tei Index In Lga Fetuses, Julia Murlewska, Przemysław Poszwa, Oskar Sylwestrzak, Maria Respondek-Liberska, Dennis Wood

Department of Obstetrics and Gynecology Faculty Papers

(1) Background: The aim of this study was to assess the RV (right ventricle) and LV (left ventricle) Tei index in large for gestational age (LGA) fetuses with a single 360-degree umbilical coil of the umbilical cord around the fetal neck identified by ultrasound in the third trimester of gestation. (2) Methods: The RV and LV Tei index for the cardiac function were measured in 297 singleton pregnancies, and we identified 25 LGA fetuses. There were 48% of LGA fetuses with a nuchal umbilical cord—LGA/NC—larger for gestational age fetuses with a nuchal cord. NC was detected with a color Doppler …

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant …

Despite modest clinical improvement with anti-vascular endothelial growth factor antibody (AVA) therapy in ovarian cancer, adaptive resistance is ubiquitous and additional options are limited. A dependence on glutamine metabolism, via the enzyme glutaminase (GLS), is a known mechanism of adaptive resistance and we aimed to investigate the utility of a GLS inhibitor (GLSi). Our in vitro findings demonstrated increased glutamine abundance and a significant cytotoxic effect in AVA-resistant tumors when GLSi was administered in combination with bevacizumab. In vivo, GLSi led to a reduction in tumor growth as monotherapy and when combined with AVA. Furthermore, GLSi initiated after the emergence …

EphA2 tyrosine kinase is upregulated in many cancers and correlated with poor survival of patients, including those with endometrial cancer. EphA2-targeted drugs have shown modest clinical benefit. To improve the therapeutic response to such drugs, we performed a high-throughput chemical screen to discover novel synergistic partners for EphA2-targeted therapeutics. Our screen identified the Wee1 kinase inhibitor, MK1775, as a synergistic partner to EphA2, and this finding was confirmed using both in vitro and in vivo experiments. We hypothesized that Wee1 inhibition would sensitize cells to EphA2-targeted therapy. Combination treatment decreased cell viability, induced apoptosis, and reduced clonogenic potential in endometrial …

Visualization Of Preimplantation Uterine Fluid Absorption In Mice Using Alexa Fluor™ 488 Hydrazide†, Yuehuan Li, Taylor Elijah Martin, Jonathan Matthew Hancock, Rong Li, Suvitha Viswanathan, John P Lydon, Yi Zheng, Xiaoqin Ye

Faculty, Staff and Students Publications

Uterine fluid plays important roles in supporting early pregnancy events and its timely absorption is critical for embryo implantation. In mice, its volume is maximum on day 0.5 post-coitum (D0.5) and approaches minimum upon embryo attachment ~D4.0. Its secretion and absorption in ovariectomized rodents were shown to be promoted by estrogen and progesterone (P4), respectively. The temporal mechanisms in preimplantation uterine fluid absorption remain to be elucidated. We have established an approach using intraluminally injected Alexa Fluor™ 488 Hydrazide (AH) in preimplantation control (RhoAf/f) and P4-deficient RhoAf/fPgrCre/+ mice. In control mice, bulk entry (seen as smeared cellular staining) via uterine …
