Strategies For Safe And Effective Treatment Of Patients With Alzheimer Disease, Jafar Alabdullah, Ahmed Almuntashiri

Community & Environmental Health Faculty Publications

Alzheimer disease is a progressive neurodegenerative disorder that causes cognition impairment and memory loss, affecting activities in daily living. In the United States, an estimated 4.5 million people have AD and this figure is expected to reach 14 million by 2050. Because patients with AD experience a deterioration of their mental functions, patients need more help with their activities of daily living, including oral hygiene, as their AD progresses. Studies have found that individuals with AD often experience poor oral health. As advanced age is a risk factor for AD and the number of older adults in the US continues …

COPD, chronic bronchitis (CB) and active smoking have all been associated with goblet cell hyperplasia (GCH) in small studies. Active smoking is strongly associated with CB, but there is a disconnect between CB clinical symptoms and pathology. Chronic cough and sputum production poorly correlate with the presence of GCH or COPD. We hypothesized that the primary determinant of GCH in ever smokers with or without airflow obstruction is active smoking. Goblet Cell Density (GCD) was measured in 71 current or former smokers [32 subjects without COPD and 39 COPD subjects]. Endobronchial mucosal biopsies were stained with Periodic Acid Schiff-Alcian Blue, …

Hokanson, Terri H Beaty, Elizabeth A. Regan, Stephen I. Rennard, Christina Wern, Michael R. Jacobs, Ruth Tal-Singer, Barry J. Make, Gregory L. Kinney, Copdgene Investigators

Journal Articles: Pulmonary & Critical Care Med

PURPOSE: Medication patterns include all medications in an individual's clinical profile. We aimed to identify chronic co-morbidity treatment patterns through medication use among COPDGene participants and determine whether these patterns were associated with mortality, acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and quality of life.

MATERIALS AND METHODS: Participants analyzed here completed Phase 1 (P1) and/or Phase 2 (P2) of COPDGene. Latent class analysis (LCA) was used to identify medication patterns and assign individuals into unobserved LCA classes. Mortality, AECOPD, and the St. George's Respiratory Questionnaire (SGRQ) health status were compared in different LCA classes through survival analysis, logistic …

Executive Summary

Parental Nutrition Health Literacy and Children’s Health

Problem: The problem identified in the following study is that overweight and obesity is associated with comorbidities that contribute to chronic diseases such as depression, decreased academic performance, type 2 diabetes, cardiac disease and others (Allesio, 2018; Barlow & Expert Committee, 2007). Demographics reveal obesity prevalence among children and adolescents to be 18.9% in the lowest income group, 19.9% in the middle-income group, and 10.9% in the highest income group (CDC, 2018). School and home environments are especially influential in affecting school-age children’s health behaviors (Luesse, Paul, Koch, Contendo, & Marsick, …

INTRODUCTION: Cachexia contributes to increased mortality and reduced quality of life in Chronic Obstructive Pulmonary Disease (COPD) and may be associated with underlying gene expression changes. Our goal was to identify differential gene expression signatures associated with COPD cachexia in current and former smokers.

METHODS: We analyzed whole-blood gene expression data from participants with COPD in a discovery cohort (COPDGene, N = 400) and assessed replication (ECLIPSE, N = 114). To approximate the consensus definition using available criteria, cachexia was defined as weight-loss > 5% in the past 12 months or low body mass index (BMI) (<  20 kg/m

RESULTS: The prevalence of …

Improving The Evaluation Of Copd Exacerbation Treatment Effects By Accounting For Early Treatment Discontinuations: A Post-Hoc Analysis Of Randomized Clinical Trials., Agnieszka Król, Robert Palmér, Virginie Rondeau, Stephen I. Rennard, Ulf G. Eriksson, Alexandra Jauhiainen

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Chronic obstructive pulmonary disease (COPD) clinical trials aimed at evaluating treatment effects on exacerbations often suffer from early discontinuations of randomized treatment. Treatment discontinuations imply a loss of information and should ideally be considered in the statistical analysis of trial results, particularly if the discontinuations are related to the disease or treatment itself. Here, we explore this issue by investigating (1) whether there exists an association between the risks of exacerbation and treatment discontinuation in COPD clinical trials and (2) whether disregarding this association can cause bias in exacerbation treatment effect estimates. We focus on the hypothetical estimand, i.e. …

Agonist-Specific Desensitization Of Pge2-Stimulated Camp Signaling Due To Upregulated Phosphodiesterase Expression In Human Lung Fibroblasts, Francisco J. Nunez, Nancy Schulte, David M. Fogel, Joel Michalski, Stephen I. Rennard, Raymond B. Penn, Myron L. Toews, Rennolds S. Ostrom

Journal Articles: Pulmonary & Critical Care Med

Pulmonary fibrosis is characterized by fibroblasts persisting in an activated form, producing excessive fibrous material that destroys alveolar structure. The second messenger molecule cyclic 3',5'-adenosine monophosphate (cAMP) has antifibrotic properties, and prostaglandin E2 (PGE2) can stimulate cAMP production through prostaglandin E (EP)2 and EP4 receptors. Although EP receptors are attractive therapeutic targets, the effects of long-term exposure to PGE2 have not been characterized. To determine the effects of long-term exposure of lung fibroblasts to PGE2, human fetal lung (HFL)-1 cells were treated for 24 h with 100 nM PGE2 or other cAMP-elevating agents. cAMP levels stimulated by acute exposure to …

Use Of Kalman Filtering In State And Parameter Estimation Of Diabetes Models, Cassidy Le

HMC Senior Theses

Diabetes continues to affect many lives every year, putting those affected by it at higher risk of serious health issues. Despite many efforts, there currently is no cure for diabetes. Nevertheless, researchers continue to study diabetes in hopes of understanding the disease and how it affects people, creating mathematical models to simulate the onset and progression of diabetes. Recent research by David J. Albers, Matthew E. Levine, Andrew Stuart, Lena Mamykina, Bruce Gluckman, and George Hripcsak¹ has suggested that these models can be furthered through the use of Data Assimilation, a regression method that synchronizes a model with a …

Machine Learning Prediction Of Glioblastoma Patient One-Year Survival, Andrew Du '20, Warren Mcgee, Jane Y. Wu

Student Publications & Research

Glioblastoma (GBM) is a grade IV astrocytoma formed primarily from cancerous astrocytes and sustained by intense angiogenesis. GBM often causes non-specific symptoms, creating difficulty for diagnosis. This study aimed to utilize machine learning techniques to provide an accurate one-year survival prognosis for GBM patients using clinical and genomic data from the Chinese Glioma Genome Atlas. Logistic regression (LR), support vector machines (SVM), random forest (RF), and ensemble models were used to identify and select predictors for GBM survival and to classify patients into those with an overall survival (OS) of less than one year and one year or greater. With …

Galileo once said, “You cannot teach a man anything, you can only help him find it within himself.” (Goodreads, 2020). I have often pondered upon how best I could use this advice. I have been an educator for 24 years and have loved every minute of it. During this time, I have seen students of all cadres come and go, but they all have one thing in common - their innate fear of written assessments. In general, students in high school tend to have a different perspective on education than their adult counterparts - they tend to procrastinate, are usually …

Cerium Oxide Nanoparticles And Beneficial Bacteria: Two Novel Treatments For Eradicating Bacteria Associated With Prosthetic Infection?, Etta Conteh

Honors Undergraduate Theses

The purpose of this thesis was to investigate new possible compounds that can be used to treat orthopedic implant infections caused by bacterial pathogens. Current treatment includes the use of antibiotics and the DAIR procedure, which stands for debridement, antibiotic therapy, irrigation, and retention. However, antibiotics are becoming less effective as a treatment due to bacteria gaining antibiotic resistance. Two bacterial species involved in orthopedic implant infections are P. aeruginosa and S. aureus. This thesis investigated cerium oxide nanoparticles and L. fermentum, a beneficial bacterium, as possible treatments to stop bacterial growth and the formation of biofilm. This …

The Relationship Between Community Health Worker Supply And The Rate Of Preventable Hospitalizations Of Rural Latinos With Diabetes, Danielle O. Mapp

Honors Undergraduate Theses

The ever-increasing prevalence of diabetes mellitus and its associated healthcare costs in the United States has led to our healthcare system's need for cost-effective health resources and chronic disease management. The interventions of Community Health Workers (CHWs) can cost-effectively improve population health and prevent the unnecessary utilization of some medical services especially in rural, low-income, minority populations, where there is often limited access to healthcare. The purpose of this study is to investigate the relationship between the number of total CHWs in rural counties and the mean diabetes-related preventable hospitalization rates in Latino patients diagnosed with diabetes in those rural …

The Effects Of Roundup On The Life History, Stress Response, And Immune Function Of The Yellow Fever Mosquito, Aedes Aegypti, Lindsay E. Martin

Honors Undergraduate Theses

Aedes aegypti mosquitoes, vectors for many human diseases, begin life as larvae developing in water, potentially exposed to runoff with herbicides and pesticides. This study serves as a novel investigation into the transstadial effects of exposure to Roundup on A. aegypti life history, immunity, and stress response and aims to account for these effects in an R0 model for vectorborne disease transmission. Prior work has shown that Roundup negatively affects mosquito life history. I hypothesized that larval exposure to the maximum sublethal dose of Roundup (7189µg/L) would negatively impact A. aegypti life history, immunity (candidate gene approach), and stress response …

Development Of A Sox9 Reporter Cell For High-Throughput Chondrogenic Assessment, Alyssa R. Mickle

Honors Undergraduate Theses

Osteoarthritis (OA) is a debilitating disease caused by the deterioration of articular cartilage and is a leading cause of disability in the United States and worldwide. Much current research into improved treatment for this disease is focused on tissue engineering through the growth of cartilage sheets made by articular chondrocytes. However, as chondrocytes proliferate in vitro, they also lose their ability to produce dense extracellular matrix, a necessary component of articular cartilage conferring mechanical strength. SOX9, a transcriptional activator, increases type II collagen expression, a key articular cartilage extracellular matrix component. Thus, SOX9 promotes an articular cartilage phenotype. Therefore, …

Detection Of Point Mutations Conferring Gentamicin Resistance In Escherichia Coli Using A Split-G4 Probe, Michael J. Greenberg

Honors Undergraduate Theses

The objective of this project was to develop a DNA hybridization sensor that can detect the presence of E. coli and reveal its resistance to the drug gentamicin. This probe will enable rapid and user-friendly diagnostics of E. coli infections and analysis of bacterial gentamicin-susceptibility profile by interrogation of a fragment of E. coli 16S rRNA bearing a substitution in the gentamicin-resistant cells. The sensor is promising for the point-of-care use to provide a timely UTI diagnostic solution. A quick diagnosis of E. coli infection and antibiotic resistance is crucial for treatment. To design a hybridization probe, we proposed a …

There are few data regarding disparities in overall survival (OS) between Asian and white men with metastatic castration-resistant prostate cancer (mCRPC). We compared OS of Asian and white mCRPC men treated in phase III clinical trials with docetaxel and prednisone (DP) or a DP-containing regimen. Individual participant data from 8820 men with mCRPC randomly assigned on nine phase III trials to receive DP or a DP-containing regimen were combined. Men enrolled in these trials had a diagnosis of prostate adenocarcinoma. The median overall survival was 18.8 months (95% confidence interval [CI] = 17.4 to 22.1 months) and 21.2 months (95% …

The Interleukin-12 Family Of Cytokines And Receptor Signaling In Graft-Versus-Host Disease, David Bastian

MUSC Theses and Dissertations

Allogeneic hematopoietic stem cell transplantation (allo-HCT) is an effective means by which to treat a wide variety of diseases resulting from dysfunctional hematopoiesis due to a potent anti-tumor response known as the graft-versus-tumor (GVT) effect after chemotherapy and/or irradiation. The necessity of donor T cells to mediate GVT is offset by the consequential development of graft-versus-host disease (GVHD); a leading cause of mortality among allo- HCT recipients. The IL-12 family of cytokines signals through Janus Kinase 2 (JAK2) and is comprised of IL-12, IL-23, IL-27, IL-35 and IL-39. IL-12 (p35+p40) and IL-23 (p19+p40) have well documented proinflammatory functions responsible for …

Mast Cells As Novel Effector Cells In The Pathogenesis Of Chronic Graft-Versus-Host Disease, Ethan Strattan

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Hematopoietic stem cell transplantation (HSCT) is most commonly a treatment for inborn defects of hematopoiesis or acute leukemias. Widespread use of HSCT, a potentially curative therapy, is hampered by onset of graft-versus-host-disease (GVHD), a condition wherein the donor cells recognize the patient tissues as non-self. GVHD can manifest anywhere from weeks to decades post-transplant and is classified as either acute or chronic GVHD, both of which are significant causes of transplant-related morbidity and mortality.

However, GVHD is a complex, multifactorial, and enigmatic disease. The factors driving GVHD at the cellular and molecular level are incompletely understood. Immunosuppression targeting T-cells has …

The Effects Of A Plant-Based Diet On Inflammation Of Patients With Cardiac Disease, Rachel L. Butcher

Honors Undergraduate Theses

Cardiac disease is the primary cause of death in the United States of America (CDC, 2017). Despite ongoing efforts and investments to improve cardiac health in the United States, most of the population will suffer from cardiovascular diseases. There is a multitude of research supporting that diet can contribute to cardiac disease, but it is less known that diet can greatly contribute to regulation and reversal of cardiovascular disease processes (Huang et al., 2012; Satija et al., 2017; Kim et al., 2019). Existing research supports the efficacy of plant-based diets to manage and reverse certain cardiac diseases (Tuso et al., …

Nhe1 And Tau Pathology: Tragically Tangled Together?, Caitlin Rae Wessel

Lewis Honors College Capstone Collection

Alzheimer’s Disease (AD) is an age-related neurodegenerative disease that poses a large public health challenge due to its complex, mixed pathology. One hallmark characteristic of AD is the development of toxic neurofibrillary tau tangles (NFT), which have been associated with the neurodegenerative component of AD. There is also compelling evidence that cerebrovascular disease puts individuals at a greater risk for experiencing the cognitive decline characteristic of dementias like AD. Past research has shown that individuals suffering from cerebrovascular disease and AD (not necessarily simultaneously) display an increased expression of the sodium-hydrogen antiporter-1 (NHE1), a plasma membrane protein ubiquitously expressed throughout …
