Empowering Choices: Patient Education For Contraceptive Confidence, Maria Anns Abraham

Nursing | Student Research Posters

The complexity of birth control options significantly impacts women's lives, with hormonal contraceptives being commonly used but often misunderstood. These contraceptives, which contain estrogen and progestin or progestin only, come in various forms such as pills, implants, IUDs, injections, the vaginal ring, and skin patches, offering benefits such as reduced menstrual cramps and ectopic pregnancy risk. However, they can also lead to adverse effects including increased blood pressure, nausea, headaches, breakthrough bleeding, and heightened risk of blood clots, with research indicating a potential link between their use and a decline in mental health. Given the prevalence of depression, particularly in …

Placental Histopathological Changes In Covid-19 And Their Associated Effects On Adverse Pregnancy Outcomes, Eric Mugambi Jan 2023

Placental Histopathological Changes In Covid-19 And Their Associated Effects On Adverse Pregnancy Outcomes, Eric Mugambi

Master of Medicine in Obstetrics and Gynecology

Introduction: Coronavirus disease (COVID-19) is a significant cause of morbidity and mortality among pregnant women. Pregnant women infected with SARS-CoV-2 are at a greater risk of pre-eclampsia/eclampsia, non-iatrogenic preterm birth, stillbirth, and small for gestational age infants/fetal growth restriction (SGA/FGR), which share a common placental etiology. Placental histopathological changes attributed to COVID-19 have been demonstrated but there is a knowledge gap in how these changes impact pregnancy outcomes particularly those of placental origin. Objectives: To investigate if there is an association between placental histopathology (maternal vascular malperfusion (MVM), fetal vascular malperfusion (FVM), acute and chronic inflammatory pathology, and other findings …


Effect Of Estrogen On Chondrogenesis In Female Articular Chondrocytes, Ebony R. Parsons Jan 2023

Effect Of Estrogen On Chondrogenesis In Female Articular Chondrocytes, Ebony R. Parsons

Honors Undergraduate Theses

As women age and transition into menopause they face a higher risk of developing osteoarthritis leading to total joint replacements. Estrogen is the primary female reproductive hormone. As a woman approaches menopause, estrogen production decreases by 100-fold. Previous research has shown that Estrogen Replacement Therapy (ERT) reduced joint replacements in post-menopausal women. However, there is a lack of research surrounding ERT's effect on chondrocyte proliferation and extracellular matrix production, particularly 3D culture extracellular matrix production. Chondrogenesis is a process of skeletal development resulting in the formation of cartilage. Chondrocytes, derived from mesenchymal progenitors, serve as the fundamental cellular component in …


Choosing The Route Of Delivery: A Discussion Of Vaginal And Cesarean Births, Camille Green Jan 2023

Choosing The Route Of Delivery: A Discussion Of Vaginal And Cesarean Births, Camille Green

Capstone Showcase

The percentage of cesarean deliveries in the United States has increased to a rate of 32.1%, double what the World Health Organization recommends as an ideal rate for maternal and fetal benefits. The majority of cesarean sections are performed on women who have never had the procedure before and this increases the risk for subsequent cesarean deliveries. Half of the indications for primary cesarean delivery were found to be non-reassuring fetal heart tracings and arrest of labor, both of which are subject to obstetric provider judgment and comfort level. Among these there is also an increasing incidence of elective primary …

Couvelaire Uterus In A Previable Pregnancy: Complication In Abruptio Placenta, Case Series From Tanzanian Tertiary Hospital, Vicky Kapesi, Brenda Moshi, Willbroad Kyejo, Ahmed Jusabani, Miriam Mgonja, Munawar Kaguta

Imaging & Diagnostic Radiology, East Africa

Introduction and importance: Couvelaire uterus, also previously known as uteroplacental apoplexy. This is a life-threatening condition resulting from bleeding into the myometrium that may extend to the parametrium and peritoneum. Couvelaire uterus is typically associated with abruptio placentae, the premature separation of the placenta. This syndrome can only be diagnosed by direct visualization during caesarean section or biopsy (or both). For this reason, its prevalence is under-reported and underestimated in the literature. Cases findings We present a rare case series of two patients with Couvelaire uterus in previable pregnancy at Aga Khan Hospital, Dar es salaam. This combination is a …

Faculty, Staff and Student Publications

Background: “Old” randomized controlled trials established breast conserving therapy (BCT) and total mastectomy (TM) equivalence for treating early breast cancer, whereas recent literature report improved survival with BCT. To reconcile this, we performed a simulation study and re-analyzed B-06 trial data.

Methods: We estimated the distributions for overall survival (OS), cumulative incidence functions for breast-cancer-specific death (BCSD) and other causes-specific death (OCSD) by BCT and TM. The restricted mean survival time (RMST) difference and hazard ratio between the two arms were estimated. Given the estimated distributions, we simulated cause-specific death times from each arm, evaluating the power to test treatment …

Machine Learning-Driven Exploration Of Drug Therapies For Triple-Negative Breast Cancer Treatment, Aman Chandra Kaushik, Zhongming Zhao

Faculty, Staff and Student Publications

Breast cancer is the second leading cause of cancer death in women among all cancer types. It is highly heterogeneous in nature, which means that the tumors have different morphologies and there is heterogeneity even among people who have the same type of tumor. Several staging and classifying systems have been developed due to the variability of different types of breast cancer. Due to high heterogeneity, personalized treatment has become a new strategy. Out of all breast cancer subtypes, triple-negative breast cancer (TNBC) comprises ∼10%-15%. TNBC refers to the subtype of breast cancer where cells do not express estrogen receptors, …
