Androgen Receptor Expression And Associated Clinico-Pathologic Features In Primary Breast Cancer From Kenya, Joshua Kibera Chege

Master of Medicine in Anatomic Pathology

Introduction: Breast cancer is a heterogeneous group of diseases classified into various subtypes according to clinical, histological and molecular features as well as by the expression of prognostic and predictive biomarkers. New biomarkers are being studied which may be therapeutic targets in various breast cancer subtypes particularly triple-negative breast cancer. Recent studies show that androgen receptor (AR) expression can be used as a prognostic marker and there is evidence that anti-androgen therapy may be beneficial in oestrogen receptor negative breast cancer. Retrospective studies show that patients with breast cancers co-expressing androgen receptor and oestrogen receptor have a favourable prognosis and …

Structure-Functional Prediction And Analysis Of Cancer Mutation Effects In Protein Kinases, Anshuman Dixit, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

A central goal of cancer research is to discover and characterize the functional effects of mutated genes that contribute to tumorigenesis. In this study, we provide a detailed structural classification and analysis of functional dynamics for members of protein kinase families that are known to harbor cancer mutations. We also present a systematic computational analysis that combines sequence and structure-based prediction models to characterize the effect of cancer mutations in protein kinases. We focus on the differential effects of activating point mutations that increase protein kinase activity and kinase-inactivating mutations that decrease activity. Mapping of cancer mutations onto the conformational …

A Review Of Critical Care Management Of Maternal Sepsis, Madiha Hashmi, Fazal Hameed Khan

Department of Anaesthesia

Sepsis is a leading cause of preventable maternal mortality in developing countries due to poverty, home deliveries by untrained persons in unhygienic conditions, limited access to healthcare facilities and lack of availability of antibiotics. Recent confidential enquiries into maternal deaths from the developed nations have revealed an increase in maternal mortality secondary to genital tract sepsis and provision of suboptimal critical care. Early recognition of critical illness in obstetric patients, involvement of intensive care teams earlier and provision of same standard of critical care to pregnant women as non-pregnant patients while being mindful of the altered maternal physiology and fetal …

Anesthesia For Cardiac Catheterization Procedures, A Hamid

Department of Anaesthesia

Anesthesiologist's involvement for the purpose of diagnostic and interventional procedures in cardiac catheterization laboratory has been evolving particularly since last two decades. Catheterization laboratory environment poses certain challenges for the anesthesiologist including unfamiliar remote location, exposure to radiation, limited help from colleagues and communication with cardiologists. Anesthesiologists working in catheterization laboratory are required to have adequate knowledge of the environment, personnel, fluoroscope, echocardiography and type of radio contrast dye during the procedure. Anyone who is exposed to radiation environment is expected to protect himself from the exposure and must also wear a dosimeter for cumulative exposure tracing.There is no ideal …

Identifying Factors Associated With The Uptake Of Prevention Of Mother To Child Hiv Transmission Programme In Tigray Region, Ethiopia: A Multilevel Modeling Approach, Wondwossen Lerebo, Steven Callens, Debra Jackson, Christina Zarowsky, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Prevention of mother to child HIV transmission (PMTCT) remains a challenge in low and middle-income countries. Determinants of utilization occur – and often interact - at both individual and community levels, but most studies do not address how determinants interact across levels. Multilevel models allow for the importance of both groups and individuals in understanding health outcomes and provide one way to link the traditionally distinct ecological- and individual-level studies. This study examined individual and community level determinants of mother and child receiving PMTCT services in Tigray region, Ethiopia.

Methods: A multistage probability sampling method was used for this …

Pediatric Cerebral Palsy In Africa: A Systematic Review, Kirsten A. Donald, Pauline Samia, Angelina Kakooza-Mwesige, David Bearden

Paediatrics and Child Health, East Africa

Cerebral palsy is a common neurologic problem in children and is reported as occurring in approximately 2-2.5 of 1000 live births globally. As is the case with many pediatric neurologic conditions, very little has been reported on this condition in the African context. Resource-limited settings such as those found across the continent are likely to result in a different spectrum of etiologies, prevalence, severity as well as management approaches. This review aims to establish what has been reported on this condition from the African continent so as to better define key clinical and research questions.

Sexual Violence And Sub-Saharan Migrants In Morocco: A Community-Based Participatory Assessment Using Respondent Driven Sampling, Ines Keygnaert, Abdessamad Dialmy, Altay Manço, Jeroen Keygnaert, Nicole Vettenburg, Kristien Roelens, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: The European Union contracted Morocco to regulate migration from so-called “transit migrants” from Morocco to Europe via the European Neighbourhood Policy. Yet, international organisations signal that human, asylum and refugee rights are not upheld in Morocco and that many sub-Saharan migrants suffer from ill-health and violence. Hence, our study aimed at 1) investigating the nature of violence that sub-Saharan migrants experience around and in Morocco, 2) assessing which determinants they perceive as decisive and 3) formulating prevention recommendations.

Methods: Applying Community-Based Participatory Research, we trained twelve sub-Saharan migrants as Community Researchers to conduct in-depth interviews with peers, using Respondent …

Importance Of Bacillithiol In The Oxidative Stress Response Of Staphylococcus Aureus, Ana C. Posada, Stacey L. Kolar, Renata G. Dusi, Patrica Francois

Dartmouth Scholarship

In Staphylococcus aureus, the low-molecular-weight thiol called bacillithiol (BSH), together with cognate S-transferases, is believed to be the counterpart to the glutathione system of other organisms. To explore the physiological role of BSH in S. aureus, we constructed mutants with the deletion of bshA (sa1291), which encodes the glycosyltransferase that catalyzes the first step of BSH biosynthesis, and fosB (sa2124), which encodes a BSH-S-transferase that confers fosfomycin resistance, in several S. aureus strains, including clinical isolates. Mutation of fosB or bshA caused a 16- to 60-fold reduction in fosfomycin resistance in these S. aureus strains. High-pressure liquid chromatography analysis, which …

Let’S Play: Understanding The Role And Significance Of Digital Gaming In Old Age, Julie A. Skalsky Brown

Theses and Dissertations--Gerontology

Despite a marked increase in the use of digital games among older persons, there is insufficient research that provides insight into the gaming experiences of this population. A major demographic shift within the senior gaming market has ushered in a new perspective on the use of digital games as a tool for physical and cognitive health, and improved socialization. It is proposed that individual notions of play, which are developed over the life course, influence digital game play engagement and interaction preferences, and contribute to well-being. This study explored how self-perceptions of play over the course of the senior gamer’s …

Molecular Actions Of The Novel Histone Deacetylase Inhibitor Cg-1521 In Models Of Inflammatory Breast Cancer, Namita Chatterjee

Legacy Theses & Dissertations (2009 - 2024)

Inflammatory breast cancer (IBC) is a rare and particularly lethal form of breast cancer. Despite aggressive therapeutic approaches, the 5-year survival rate is only 34%. As this disease is severely understudied, we have investigated the therapeutic potential of the novel hydroxamic acid-derived histone deacetylase inhibitor (HDACi), CG-1521 in comparison to a structurally similar compound, Trichostatin A (TSA) in two IBC cell lines: SUM149PT and SUM190PT. In these cells, CG-1521 and TSA induce dose- and time-dependent induction of cell cycle arrest and apoptosis regardless of the presence of 17β-estradiol (E2). Interestingly, the cell lines have considerably different sensitivities to these treatments …

A Simplified Score To Quantify Comorbidity In Copd, Nirupama Putcha, Milo A. Puhan, M. Bradley Drummond, Meilan K. Han, Elizabeth A. Regan, Nicola A. Hanania, Carlos H. Martinez, Marilyn Foreman, Surya P. Bhatt, Barry Make, Joe Ramsdell, Dawn L. Demeo, R. Graham Barr, Stephen I. Rennard, Fernando Martinez, Edwin K. Silverman, James Crapo, Robert A. Wise, Nadia N. Hansel

Journal Articles: Pulmonary & Critical Care Med

IMPORTANCE: Comorbidities are common in COPD, but quantifying their burden is difficult. Currently there is a COPD-specific comorbidity index to predict mortality and another to predict general quality of life. We sought to develop and validate a COPD-specific comorbidity score that reflects comorbidity burden on patient-centered outcomes.

MATERIALS AND METHODS: Using the COPDGene study (GOLD II-IV COPD), we developed comorbidity scores to describe patient-centered outcomes employing three techniques: 1) simple count, 2) weighted score, and 3) weighted score based upon statistical selection procedure. We tested associations, area under the Curve (AUC) and calibration statistics to validate scores internally with outcomes …

Mayer, Stephen I. Rennard, Bartolome Celli, Bruce E. Miller, Nick Locantore, Ruth Tal-Singer, Soumitra Ghosh, Chris Larminie, Glyn Bradley, John H. Riley, Alvar Agusti, Edwin K. Silverman, Albert-László Barabási

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: An important step toward understanding the biological mechanisms underlying a complex disease is a refined understanding of its clinical heterogeneity. Relating clinical and molecular differences may allow us to define more specific subtypes of patients that respond differently to therapeutic interventions.

RESULTS: We developed a novel unbiased method called diVIsive Shuffling Approach (VIStA) that identifies subgroups of patients by maximizing the difference in their gene expression patterns. We tested our algorithm on 140 subjects with Chronic Obstructive Pulmonary Disease (COPD) and found four distinct, biologically and clinically meaningful combinations of clinical characteristics that are associated with large gene expression …

Measuring The Impact Of Contraceptive Use On Unintended Pregnancy And Other Health Outcomes, Step Up Research Programme Consortium

Reproductive Health

This brief describes several statistical models that have been developed to estimate the number of health outcomes that will be averted because of contraceptive use. Concerns have been expressed that this range of approaches—which overlap in the impacts they estimate, but sometimes use different inputs, mathematical algorithms, and assumptions, and may produce different results—may be confusing for policymakers, managers, and donors who want to measure or evaluate these impacts. To address these concerns, the STEP UP consortium convened two expert meetings to review the estimation methods used; come to consensus on methodologies and assumptions, where possible; and provide guidance to …

Correlates Of 25-Hydroxyvitamin D Among Chinese Breast Cancer Patients, Liang Shi, Sarah Nechuta, Yu-Tang Gao, Ying Zheng, Tsogzolmaa Dorjgochoo, Jie Wu, Qiuyin Cai, Wei Zheng, Wei Lu, Xiao Ou Shu

Peer Reviewed Articles

Background

Few studies have investigated vitamin D status in association with modifiable lifestyle factors and clinical characteristics among breast cancer patients, with no studies among Chinese women, who may be at higher risk of vitamin D deficiency. We aimed to evaluate circulating 25-hydroxyvitamin D (25(OH)D) levels in association with clinical and lifestyle factors among 1,940 Chinese breast cancer patients.

Methods

Participants included breast cancer cases aged 22–77 from a population-based case-control study conducted in Shanghai, China during 1996–1998 (n = 1,044) and 2002–2005 (n = 896). Circulating 25(OH)D levels were measured in plasma samples (95% collected ≤6 months post-diagnosis). Prevalence …

Tmprss2-Erg Regulation Of Androgen Biosynthetic Enzyme Expression, Dht Synthesis, And Androgen Receptor Activation In Prostate Cancer, Katelyn Ann Powell

Wayne State University Dissertations

Intratumoral androgen synthesis in prostate cancer (PCa) contributes to the development of castration-resistant prostate cancer (CRPC). Several enzymes responsible for androgen biosynthesis have been shown to be overexpressed in CRPC, thus, contributing to CRPC in a castrated environment. Although intratumoral androgen synthesis is thought to contribute to the development and progression of CRPC, currently little is known regarding the regulation of androgen biosynthetic enzyme gene expression in PCa. The TMPRSS2-ERG transcription factor has been shown to be present in primary PCa tumors as well as CRPC tumors. The hypothesis was investigated that TMPRSS2-ERG fusions regulate androgen biosynthetic enzyme (ABE) gene …

A Single-Institution Experience With Metallic Ureteral Stents: A Cost-Effective Method Of Managing Deficiencies In Ureteral Drainage, Adam S. Baumgarten, Tariq S. Hakky, Rafael E. Carrion, Jorge L. Lockhart, Philippe E. Spiess

Urology Faculty Publications

Introduction: The limitations of traditional ureteral stents in patients with deficiencies in ureteral drainage have resulted in frequent stent exchanges. The implementation of metallic stents was introduced to improve the patency rates of patients with chronic upper urinary tract obstruction, obviating the need for frequent stent exchanges. We report our clinical experiences with the use of metallic ureteral stents in the management of poor ureteral drainage.

Materials and Methods: Fifty patients underwent metallic ureteral stent placement from 2009 to 2012. Stent failure was defined as an unplanned stent exchange, need for nephrostomy tube placement, increasing hydronephrosis with stent in place, …
