The Kenya Uk Breast Cancer Awareness Week: Curriculum Codesign And Codelivery With Direct And Lived Experience Of Breast Cancer Diagnosis And Management, Bahaty Riogi, Carlo Ross, Miriam Mutebi, Rajiv V. Dave

General Surgery, East Africa

Global health education holds a paradox: the provision of global health degrees focusing on challenges in low-income and middle-income countries has increased in high-income countries, while those in these low-income and middle-income countries lack access to contribute their expertise, creating an ‘information problem’. Breast cancer is a pressing global health priority, which requires curriculum design, implementation, ownership and leadership by those with direct and lived experience of breast cancer.

The Kenya-UK Breast Cancer Awareness Week was conceptualised following the signing of the Memorandum of Understanding between the Kenyan and UK governments launching the Kenya UK Health Alliance. This alliance aims …

Arthroscopically Assisted Acromioclavicular And Coracoclavicular Reconstruction With A Looped Braided Polyester Suture Band And Buckle Device., Kurt E Stoll, Benjamin Hendy, Treg Brown, Nathaniel Cohen, Thay Q Lee, Surena Namdari, Phil Davidson

Rothman Institute Papers

Acromioclavicular (AC) joint injuries occur with a traumatic load to the lateral aspect of the shoulder and account for 9% of all shoulder girdle injuries. Rockwood classified AC joint injuries as type I though type VI, based on severity of injury, radiographic findings, and reducibility of the AC joint. Type I and II injuries are typically managed nonoperatively, whereas type IV, V, and VI are managed operatively to address the significant soft tissue disruption, persistent AC joint instability, and apical shoulder deformation. Treatment of type III injuries remain controversial. Several techniques have been described to treat AC joint injuries with …

Nanog Prion-Like Assembly Mediates Dna Bridging To Facilitate Chromatin Reorganization And Activation Of Pluripotency, Kyoung-Jae Choi, My Diem Quan, Chuangye Qi, Joo-Hyung Lee, Phoebe S Tsoi, Mahla Zahabiyon, Aleksandar Bajic, Liya Hu, B V Venkataram Prasad, Shih-Chu Jeff Liao, Wenbo Li, Allan Chris M Ferreon, Josephine C Ferreon

Faculty, Staff and Student Publications

Human NANOG expression resets stem cells to ground-state pluripotency. Here we identify the unique features of human NANOG that relate to its dose-sensitive function as a master transcription factor. NANOG is largely disordered, with a C-terminal prion-like domain that phase-transitions to gel-like condensates. Full-length NANOG readily forms higher-order oligomers at low nanomolar concentrations, orders of magnitude lower than typical amyloids. Using single-molecule Förster resonance energy transfer and fluorescence cross-correlation techniques, we show that NANOG oligomerization is essential for bridging DNA elements in vitro. Using chromatin immunoprecipitation sequencing and Hi-C 3.0 in cells, we validate that NANOG prion-like domain assembly is …

Adipocyte-Derived Serum Amyloid A Promotes Angiotensin Ii–Induced Abdominal Aortic Aneurysms In Obese C57bl/6j Mice, Preetha Shridas, Ailing Ji, Andrea C. Trumbauer, Victoria P. Noffsinger, Steve W. Leung, Adam J. Dugan, Sean E. Thatcher, Lisa A. Cassis, Frederick C. De Beer, Nancy R. Webb, Lisa R. Tannock

Internal Medicine Faculty Publications

Background: Obesity increases the risk for human abdominal aortic aneurysms (AAAs) and enhances Ang II (angiotensin II)-induced AAA formation in C57BL/6J mice. Obesity is also associated with increases in perivascular fat that expresses proinflammatory markers including SAA (serum amyloid A). We previously reported that deficiency of SAA significantly reduces Ang II-induced inflammation and AAA in hyperlipidemic apoE-deficient mice. In this study. we investigated whether adipose tissue-derived SAA plays a role in Ang II-induced AAA in obese C57BL/6J mice.

Methods: The development of AAA was compared between male C57BL/6J mice (wild type), C57BL/6J mice lacking SAA1.1, SAA2.1, and SAA3 …

Anti-Nmda-Receptor Encephalitis In A Patient With Ovarian Teratoma, Harboring Brain Histology Of Varying Developmental Stages, Seyedalireza Fatemi, Joseph Fullmer

Conference Presentation Abstracts

Anti-NMDA-receptor encephalitis is a subacute, autoimmune disorder thought to be caused by autoantibodies directed against the N-methyl-D-aspartate (NMDA) receptor. Although NMDAR encephalitis is a familiar entity to psychiatrists and neurologists, it is less commonly reported in the pathology literature. Clinical symptoms of anti-NMDAR encephalitis may mimic schizophrenia and psychotic spectrum disorders or substance-induced psychosis. Although initially described in association with ovarian teratomas in women, anti-NMDAR encephalitis has been reported in individuals without paraneoplastic association, as well as in males. Previous literature has suggested NMDA receptor expressing teratoma neurons are densely aggregated and are smaller in size. Ki-67 index can be …

The Role Of Obesity In Macrophage-Mediated Mechanisms Promoting Early-Onset Colon Cancer., Katharina Marietta Scheurlen

Electronic Theses and Dissertations

Early-onset colon cancer (EOCC) is a leading cause of cancer death among people younger than 50 years of age in the United States and is associated with metabolic dysfunction and obesity. Anti-inflammatory tumor-associated macrophages (TAM) and low Peroxisome Proliferator Activated Receptor Gamma (PPARγ) gene expression in colon cancer (CC) tissue promote tumor progression and decreased patient survival. Obesity-related hormones, such as leptin and adiponectin, have the potential to affect gene expression in TAM to promote CC progression and thereby link obesity and EOCC. The aim of this project was to identify target genes in human CC and to investigate the …

The Experience Of Scanxiety In Survivors Of Pancreatic Cancer: A Phenomenological Study., Susan Winebrenner

Electronic Theses and Dissertations

Surveillance scans can signify a crisis point in a cancer patient’s life, provoking fear and anxiety that negatively impact quality of life. Scan-related anxiety or scanxiety has been briefly discussed in the literature among lung cancer and lymphoma populations, but relatively few investigations have studied the psychological impact of routine surveillance scans during cancer survivorship. The purpose of this study was to illuminate the lived experience of scanxiety in survivors of pancreatic cancer who have undergone curative surgical resection. Hermeneutic phenomenology as applied by Heidegger provided the philosophical underpinnings for this study and van Manen’s methodological approach was used to …

Association Between Third Trimester Cerebro-Placental Ratio And Adverse Outcomes In Appropriate For Gestational Age Foetuses, Morris Wabacha Kimani

Master of Medicine in Obstetrics and Gynecology

Background: Small for gestational age (SGA) fetuses are at increased risk of adverse outcomes and appropriate vigilance is put in place in terms of antenatal and intrapartum surveillance. Appropriate for gestational age (AGA) fetuses have a lower incidence of adverse outcomes, although majority of these outcomes occur in this cohort. AGA fetuses can fail to reach their genetic growth potential due to placental insufficiency and 25 % have actually been found to have placental histological features of chronic hypoxia. Therefore, there is need to use other methods of screening for adverse perinatal outcomes apart from estimated fetal weight (EFW), with …

Increasing Patient Satisfaction Of Post-Cesarean Mothers: An Evidence-Based Practice Quality Improvement Project, Amanda Jones

DNP Projects

Introduction: The first hour after delivery, referred to as the “Golden Hour” or “Sacred Hour,” is when the mom, baby, and the support person get 1-hour of uninterrupted bonding time together. This time is critical because it promotes neonatal thermoregulation, decreases newborn stress levels, improves mother–newborn attachment, and encourages breastfeeding. Unfortunately, most cesarean births do not receive the Golden Hour and instead experience delayed bonding time.

Purpose: The purpose of this Evidence-Based Practice (EBP) project was to incorporate the Golden Hour for post-cesarean section mothers in a mid-sized community-based hospital in XXX, CT in order to increase patient satisfaction post-c-section; …

Decreasing Time To Antibiotic Administration In Febrile Neutropenic Adult Oncology Patients In The Emergency Department: An Evidence-Based Quality Improvement Project, Kristin Murray

DNP Projects

Introduction—Significance and Background: Febrile Neutropenia (FN) is the most common and serious complication of hematopoietic cancers and in patients receiving chemotherapy. Patients in this immunocompromised state have weakened immunity to fight off infection and a mortality rate of almost 10%. Thus, Infectious Diseases Society of America has identified the single most important determining factor of outcomes is the timing of antibiotic (TTA) administration and has identified the gold standard to be 60 minutes. Current practice does not follow guidelines and the current policy does not address the urgency of antibiotic administration.

Purpose: The purpose of this project is to improve …

Doctor of Nursing Practice Projects

Purpose/Background Postoperative delirium (POD) is an acute neurological condition affecting large numbers of surgical patients in various practice settings. Patients suffering from this condition face postoperative complications, increased lengths of stay, and tremendous financial burden. Understanding the contributing factors for POD, and how adjustments in intraoperative agents can prevent or reduce the incidence, is a crucial aspect of anesthesia practice. This scoping review will examine associations between POD and the intraoperative use of propofol versus dexmedetomidine with general anesthesia.

Methods Studies in this review were limited to peer-reviewed literature, published in medical and nursing journals within the last five years. …

A Study To Compare Baseline Functional Residual Capacity And Forced Vital Capacity As Predictors Of Mortality And Hospitalization In A Cohort Of Mild To Moderate Interstitial Lung Disease, Olga R. Gomez Rojas, Ehsun Naeem, Filip Ionescu, Edward Castillo, Girish B. Nair

Posters

Forced Vital Capacity (FVC) is a common parameter used to assess disease progression in patients with Interstitial lung disease (ILD) and acts as a surrogate for mortality. Previous studies suggest Functional Residual Capacity (FRC) may be an earlier predictor of disease progression in ILD. In this study, we compared predictive ability of baseline FRC to FVC to predict one-year-mortality and respiratory related hospitalization in patients with mild to moderate ILD

The Effects Of Hormonal Contraceptive Use On Perceptions Of Social Stress In Women, Ashton Jones

Biological Sciences Undergraduate Honors Theses

Hormonal contraceptives are widely used due to their efficiency in preventing pregnancy. Although women are often informed of the physical effects of hormonal contraceptives, there is little emphasis on mental effects, such as increased rates of depression and changes in social perception. The current study examined perceptions of social stress among women before beginning hormonal contraceptives, and two months after using hormonal contraceptives. I hypothesized that women would experience increased social stress after beginning hormonal contraceptives, compared to a control group of women who were also assessed twice. Results did not support this hypothesis; there was no difference in interpersonal …

Early Neonatal Mortality Is Modulated By Gestational Age, Birthweight And Fetal Heart Rate Abnormalities In The Low Resource Setting In Tanzania – A Five Year Review 2015–2019, Aisa Shayo, Pendo Mlay, Emily Ahn, Hussein Kidanto, Michael Espiritu, Jeffrey Perlman

Obstetrics and Gynaecology, East Africa

Background: Early Neonatal mortality (ENM) (<7days) remains a signifcant problem in low resource settings. Birth asphyxia (BA), prematurity and presumed infection contribute signifcantly to ENM. The study objectives were to determine: frst, the overall ENM rate as well as yearly ENM rate (ENMR) from 2015 to 2019; second, the infuence of decreasing GA (<37weeks) and BW (<2500g) on ENM; third, the contribution of intrapartum and delivery room factors and in particular fetal heart rate abnormalities (FHRT) to ENM; and fourth, the Fresh Still Birth Rates (FSB) rates over the same time period.

Methods: Retrospective cohort study undertaken in a zonal referral teaching hospital located in Northern Tanzania. Labor and delivery room data were obtained from 2015 to 2019 and included BW, GA, fetal heart rate (FHRT) abnormalities, bag mask ventilation (BMV) during resuscitation, initial temperature, and antenatal steroids use. Abnormal outcome was ENM<7days. Analysis included t tests, odds ratios (OR), and multivariate regression analysis.

Results: The overall early neonatal mortality rate (ENMR) was 18/1000 livebirths over the 5 years and did not change signifcantly comparing 2015 to 2019. Comparing year 2018 to 2019, the overall ENMR decreased signifcantly (OR 0.62; 95% confdence interval (CI) …

Efficacy Of Preoperative Manual Detorsion For Intravaginal Testicular Torsion: A Systematic Review, Ralph Ombati

Master of Medicine in General Surgery

Background: Preoperative manual detorsion for acute testicular torsion has been postulated to improve testicular salvage rates through reduction in testicular ischemia time. Manual detorsion however has several potential risks including worsening degree of torsion, incomplete detorsion and potentially missing the opportunity to perform definitive orchidopexy. Objectives: To assess the efficacy of preoperative manual detorsion compared to immediate scrotal exploration in improving testicular salvage in acute intravaginal testicular torsion. Methods: The MEDLINE, SCOPUS and AJOL databases along with the CENTRAL registry were searched for trials comparing preoperative manual detorsion to immediate scrotal exploration for acute intravaginal testicular torsion. Both randomized and …

Lumbar Motion Is Maintained With Paraspinous Tension Band For Degenerative Spondylolisthesis: Results From 24-Month Fda Study, Kee D. Kim, Rick Sasso, Serena Hu, Alan Villavicencio, S Tim Yoon, William Lavelle, Harvinder Sandhu, Hyun Bae, Jeffrey Fischgrund, Mick Perez-Cruet

Conference Presentation Abstracts

Introduction

Durable outcome for degenerative spondylolisthesis (DS) usually requires decompression and fusion. Fusion, however, places greater stress at adjacent levels with increased incidence of adjacent segment disease. A novel interspinous tension band is proposed for segmental stabilization after decompression for DS, as an alternative to fusion. An FDA IDE study (NCT03115983) compares decompression and stabilization with the tension band (treatment group) to decompression and transforaminal interbody instrumented fusion (control group) for symptomatic DS.

Methods

Prospectively enrolled IDE study subjects with 24 months postoperative radiographic follow-up were included in this analysis. X-rays obtained during the follow-up period for both the treatment …

Sanders-Brown Center on Aging Faculty Publications

Cranial radiation is important for treating both primary brain tumors and brain metastases. A potential delayed side effect of cranial radiation is neurocognitive function decline. Early detection of CNS injury might prevent further neuronal damage. Extracellular vesicles (EVs) have emerged as a potential diagnostic tool because of their unique membranous characteristics and cargos. We investigated whether EVs can be an early indicator of CNS injury by giving C57BJ/6 mice 10 Gy cranial IR. EVs were isolated from sera to quantify: 1) number of EVs using nanoparticle tracking analysis (NTA); 2) Glial fibrillary acidic protein (GFAP), an astrocyte marker; and 3) …

Discrimination And Abuse Amongst Health Care Workers In A Tertiary Hospital In Kenya, Farah Alnoor Ebrahim

Master of Medicine in Internal Medicine

Background: Discrimination is defined as the unequal or disadvantageous treatment of an individual or a group of individuals. Discrimination in the health care setting can take many forms, including gender, race, verbal or emotional abuse, physical abuse, and sexual abuse. The prevalence of discrimination varies, with common forms being gender and racial discrimination as well as verbal and emotional abuse. Workplace discrimination often leads to a hostile environment for healthcare workers, resulting in significant mental strain. Patients, their relatives, and consultants are the foremost perpetrators of discrimination and abuse across the globe. Little is known about discrimination and abuse within …

Diagnostic Utility Of Red Cell Indices In Relation To Serum Iron Indices For Evaluation Of Iron Deficiency In Heart Failure, Larry Wangai Mburu

Master of Medicine in Internal Medicine

Background: Iron deficiency (ID) in heart failure (HF) causes poorer outcomes, and evaluation using ferritin and transferrin saturation (TSAT) in our setting is hampered by cost and availability. Though the red cell indices (RCIs), routinely used for assessment of ID anaemia, have shown utility in predicting outcomes in HF, they have not been evaluated in this population for prediction of ID relative to the iron indices. A combination of the RCIs, the combined cell index (CCI), may be more accurate. Validating the diagnostic accuracy of the RCIs would improve evaluation of ID in low-resource settings and improve uptake of iron …

Diagnostic Accuracy Of Axillary Ultrasound In Predicting Nodal Metastasis Among Patients With Early Breast Cancer At Aga Khan University Hospital, Nairobi, David Mwaniki

Master of Medicine in Imaging and Diagnostic Radiology

With emerging evidence showing that the incidence of breast cancer in Kenya is increasing, there is renewed emphasis on screening, early detection, and management of breast cancer. Early breast cancer (EBC) has a better prognosis and is potentially curable. Axillary nodal metastasis is an important prognostic indicator in breast cancer. Axillary ultrasound is the best modality for assessing, and managing, the affected nodes. It is a readily available and versatile tool with several sonographic nodal characteristics suggestive of metastatic involvement having been described in previous studies. Axillary ultrasound (AUS) performance in predicting nodal metastasis has yielded variable results which are …
