Constructing Scientific Knowledge: The Understanding Of The Slow Virus, 1898-1976, Burke Hood Dial

Theses and Dissertations

Scrapie is the ovine form of the transmissible spongiform encephalopathies. The understanding of scrapie as a slow viral disease was developed through an international scientific dialogue during the first half of the twentieth century. British investigators used epidemiological and experimental observations to define its very long incubation period before the appearance of symptoms. This enabled French researchers to prove scrapie could be transmitted from sick to healthy animals and allowed them to define the etiological agent as an ultramicroscopic, filterable virus. Following this, an Icelandic scientist, Björn Sigurdsson, investigated two other ovine diseases characterized by unusually long periods between contracting …

Understanding Barriers To Genetic Testing For Sickle Cell Trait: The African-American Male Perspective, Shandrea Foster

Theses and Dissertations

Research has shown a reluctance in African-American males to pursue testing for sickle cell trait. Few studies have tried to discern what barriers are contributing to this issue within the African-American male community. Research suggests a lack of knowledge may be the biggest contributing factor. This study hypothesized there would be a significant difference in knowledge of sickle cell trait based on educational level, age, and health beliefs. African-America male participants (N=116), ages 18 and over, completed a questionnaire assessing knowledge, risk perception, health beliefs, barriers, and motivating factors within the context of sickle cell trait. One-way and two-way analysis …

Characterizing Health Behavior Information: Developing A Surveillance Text Mining Framework Using Twitter For Diet, Diabetes, Exercise, And Obesity, George Shaw Jr.

Theses and Dissertations

Previous studies have documented the relationship that exists among diabetes, diet, exercise, and obesity. Obesity increases people’s risk of developing heart disease and type 2 diabetes. Exercise and proper dieting are modifiable lifestyle behaviors that can help with reducing people’s overall weight and risk to various chronic conditions like diabetes. A national survey conducted by the Centers for Diseases Control and Prevention (CDC) is the annual Behavioral Risk Factor Surveillance Survey (BRFSS). Twitter provides researchers with a new opportunity and alternative data source to collect information regarding health behaviors using real-time data. Previous studies have demonstrated Twitter’s ability to monitor …

Initiating The Loeb Criteria In Long-Term Care, Janice Khauslender

Theses and Dissertations

Urinary tract infections are one of the most commonly reported infections in long-term care. Current practices often rely on non-specific symptoms, rather than specific genitourinary symptoms, to aid in the decision to obtain a urine culture. The literature does not support this practice due to the high prevalence of asymptomatic bacteriuria among long-term care patients, which does not have adverse outcomes when untreated. Antibiotics do not eradicate asymptomatic bacteriuria and place patients at risk of adverse reactions and increased risk of multi-drug resistant organisms. This clinical improvement project applied the Loeb criteria in two long-term care facilities to reduce the …

Understanding The Impact Of Land Use On Microbial Water Quality To Support Decisions For A Future Land Use Plan, Mohammed Tawfiq Aljassim

Theses and Dissertations

May River meandering through the Town of Bluffton, South Carolina has been known for its high level of water quality. The May River is one of the major sources of shellfish harvesting in South Carolina. Due to the non-point source pollution of fecal coliform, the water quality of the May River became degraded. As a result, shellfish harvesting classification in the May River was downgraded for the first time in its history. The rapid growth of the Town has led to a change in land use, which might be related to the increased levels of fecal coliform in the stream …

Relationship Between Self-Reported Oral Health And Self-Esteem In Two Columbia, Sc Populations, Matthew Ablonczy, Elizabeth Smith

Senior Theses

The importance of oral health to overall health cannot be overstated. For example, oral health can be used for early diagnosis of diseases such as diabetes. Furthermore, it has been well studied that self-esteem is related to oral health. Individuals with proper oral health care have more confidence to interact with others, which results in higher self-esteem. Those who lack the ability to pay for oral healthcare are thus at a great disadvantage. The present study sought to investigate the relationship between oral health and self-esteem in two Columbia, SC populations through surveying. There were two study populations, students at …

Faculty Publications

Objective Gastro-oesophageal reflux disease (GORD) is a common comorbidity among patients with rheumatoid arthritis (RA). While GORD has been attributed to the antirheumatic medications, no studies of human cohorts have investigated a link between GORD and RA. This study investigates whether GORD is associated with a subsequent RA diagnosis over a 5-year follow-up using a population-based dataset.

Setting Taiwan

Participants We used data from the Taiwan Longitudinal Health Insurance Database. The study group consisted of 13 645 patients with an ambulatory claim showing a GORD diagnosis. We used propensity score matching to select 13 645 comparison patients (one per study …

Novel Mosquito Control: A Natural Approach To Reducing And Repelling Mosquito Populations, Vinita Cheepurupalli

Journal of the South Carolina Academy of Science

Mosquitoes are a major concern to human health because they serve as vectors to pass agents that cause diseases, such as malaria, the Zika virus, and the West Nile virus, which can have a multitude of harmful side effects, such as seizures, conjunctivitis, and death. The overuse of commercial mosquitocidal agents have caused mosquitoes to develop resistance and cause harm to humans and the environment. To prevent this, natural extracts could be used. The purpose of this experiment was to test various plant extracts for their effectiveness in acting as larvicides, adulticides, and repellents against Culex quinquefasciatus mosquitoes. It was …

Mechanism Of Action Of American Ginseng And Its Components In The Treatment Of Ulcerative Colitis, Anusha Chaparala

Theses and Dissertations

Inflammatory bowel diseases (IBD), mainly ulcerative colitis (UC), Crohn’s disease (CD), are chronic, idiopathic, inflammatory diseases of the gastrointestinal tract affecting millions of people worldwide. The incidence of IBD is steadily increasing in the modern world due to changes in dietary habits and other environmental influences that originated from industrialization. The etiology is poorly understood but is believed to be a combination of genetic predisposition, environmental factors, and overactive immune system. UC is characterized by inflammation and ulceration of colonic mucosa and rectum and has a higher incidence than CD. Aside from severely affecting the quality of life of the …

The Parasite Extinction Assessment & Red List: An Open-Source, Online Biodiversity Database For Neglected Symbionts, Colin J. Carlson, Oliver C. Muellerklein, Anna J. Phillips, Kevin R. Burgio, Giovanni Castaldo, Carrie A. Cizauskas, Graeme S. Cumming, Tad Dallas, Jorge Doña, Nyeema Harris, Roger Jovani, Zhongqi Miao, Heather Proctor, Hyun Seok Yoon, Wayne M. Getz

Faculty Publications

Parasite conservation is a rapidly growing field at the intersection of ecology, epidemiology, parasitology, and public health. The overwhelming diversity of parasitic life on earth, and recent work showing that parasites and other symbionts face severe extinction risk, necessitates infrastructure for parasite conservation assessments. Here, we describe the release of the Parasite Extinction Assessment & Red List (PEARL) version 1.0, an open-access database of conservation assessments and distributional data for almost 500 macroparasitic invertebrates. The current approach to vulnerability assessment is based on range shifts and loss from climate change, and will be expanded as additional data (e.g., host-parasite associations …

Climate change is a well-documented driver of both wildlife extinction and disease emergence, but the negative impacts of climate change on parasite diversity are undocumented. We compiled the most comprehensive spatially explicit data set available for parasites, projected range shifts in a changing climate, and estimated extinction rates for eight major parasite clades. On the basis of 53,133 occurrences capturing the geographic ranges of 457 parasite species, conservative model projections suggest that 5 to 10% of these species are committed to extinction by 2070 from climate-driven habitat loss alone. We find no evidence that parasites with zoonotic potential have a …

Capacity Of Blood Plasma Is Higher In Birds Breeding In Radioactively Contaminated Areas, Magdalena Ruiz-Rodríguez, Anders P. Møller, Timothy Mousseau, Juan J. Soler

Faculty Publications

Background Environmental pollution in general, and radioactive contamination in particular, may deeply affect host-parasite relationships and their consequences for the evolution of organisms. The nuclear accident that occurred more than 30 years ago in Chernobyl resulted in significant changes in diversity and richness of microbial communities that could influence characteristics of animal-bacteria interactions, including host immune responses and competitive interference by bacteria. Given the high mortality rate of birds breeding in radioactively contaminated zones, those with stronger defences against infections should experience significant fitness advantages.

Methodology/Principal Findings Here we characterized antimicrobial capacity of barn swallows (Hirundo rustica) from different Ukrainian …

Association Of Alzhemier's Disease With Hepatitis C Among Patients With Bipolar Disorder, Herng-Ching Lin, Sudha Xirasagar, Hsin-Chien Lee, Chung-Chien Huang, Chao-Hung Chen

Faculty Publications

Associations of hepatitis C virus infection with Alzheimer’s disease have not been studied among higher risk, bipolar disorder patients. This population-based case-control study investigated the risks of hepatitis C virus infection among Alzheimer’s disease patients with bipolar disorder in the years preceding their Alzheimer’s disease diagnosis. We used 2000–2013 data from the Longitudinal Health Insurance Database in Taiwan. Among patients with bipolar disorder, 73 were diagnosed with Alzheimer’s disease (cases), who were compared with 365 individuals with bipolar disorder but without Alzheimer’s disease (randomly selected controls matched on sex, age, and index year with cases). Prior claims (before the diagnosis …

Predicting Cryptic Links In Host-Parasite Networks, Tad Dallas, Andrew W. Park, John M. Drake

Faculty Publications

Networks are a way to represent interactions among one (e.g., social networks) or more (e.g., plant-pollinator networks) classes of nodes. The ability to predict likely, but unobserved, interactions has generated a great deal of interest, and is sometimes referred to as the link prediction problem. However, most studies of link prediction have focused on social networks, and have assumed a completely censused network. In biological networks, it is unlikely that all interactions are censused, and ignoring incomplete detection of interactions may lead to biased or incorrect conclusions. Previous attempts to predict network interactions have relied on known properties of network …

Friends, Enemies, Or Hitchhikers? Exploring The Relationship Between Fungus, Butterfly, And Rest Plant At Fort Jackson, South Carolina, Miranda F. Hannah

Senior Theses

This study was undertaken to investigate the relationships between butterflies as pollinators, host plants, and fungi. Euptoieta claudia (Lepidoptera: Nymphalidae) butterflies were captured on flowers at McCrady Training Center, Fort Jackson, South Carolina and the fungi isolated from the legs and abdomens of these butterflies was identified and analyzed. Butterflies were found to carry a variety of fungal species including Penicillium, Cladosporium, Curvularia, Fusarium, and Aspergillus. Butterflies carrying the highest quantity of different species of fungi were captured on Passiflora incarnata flowers, and the number of fungal species per butterfly seems to be due to chance. The most common species …

Pilot Program To Provide Hiv Pep To Sexual Assault Survivors, Ellen Stahlman

Senior Theses

Currently, South Carolina has no standardized guidelines for the prescription and financial obligations for HIV prophylactic treatment post sexual assault. With South Carolina’s high rates of sexual assault and HIV/AIDS, there should be implementation of a program to address these issues. In 2014, South Carolina Office of Victim Assistance (SOVA) contacted the USC Immunology Clinic along with Palmetto Health Richland hospital in order to implement a pilot program in order to provide funding for sexual assault survivors’ treatment preventing HIV. Much communication had to take place in order for all aspects of the process to work efficiently. Emergency departments first …

Zika And The Failure To Act Under The Police Power, Jacqueline Fox

Faculty Publications

Zika is a mosquito-borne and sexually transmitted disease that is a dangerous threat to pregnant women, causing catastrophic birth defects in a large percentage of fetuses when their mothers become infected while pregnant. It raises numerous issues related to abortion, birth control, poverty, and women’s control over their procreative choices. While the United States received ample warning from January 2016 onward that it was at risk of local transmission of this virus and public health officials at all levels generally behaved properly, the state and federal legislative responses in the summer of 2016 were entirely inadequate. For example, no state …

Application Of Fluoroquinolone Resistance Score In Management Of Complicated Urinary Tract Infections, Ansal Shah, Julie Ann Justo, P Brandon Bookstaver, Joseph Kohn, Helmut Albrecht, Majdi N. Al-Hasan

Faculty Publications

The fluoroquinolone resistance score (FQRS) predicts the probability of fluoroquinolone resistance with good discrimination. The score has been derived from patients with bloodstream infections caused by Gram-negative bacteria and is based on fluoroquinolone use within the past 6 months, among other clinical and health care exposure criteria. This study aims to examine the utility of the FQRS in patients with complicated urinary tract infections (cUTI) and determine whether extension of prior fluoroquinolone use to 12 months improves model discrimination. Adults with cUTI at Palmetto Health in central South Carolina, USA, from 1 April 2015 through 31 July 2015 were prospectively …

Topics In Group Testing With Multiple Infections, Peijie Hou

Theses and Dissertations

Group testing, dating back to the early 1940s, was first proposed to screen for syphilis among US inductees during World War II (Dorfman, 1943). Since then, the benefits of reducing testing costs by employing group testing have been demonstrated in many areas, such as drug discovery, genetics, and infectious disease testing. Traditionally, statistical research in group testing has largely been motivated by applications involving a single infection. With the recent development of multiplex assays that can diagnose multiple infections simultaneously, generalizing the existing group testing literature to incorporate multiple infections is a natural and necessary next step. This dissertation consists …

Emerging Antimicrobial Research Against Superbugs: Perspectives From A Polymer Laboratory, Mitra S. Ganewatta, Md Anisur Rahman, Chuanbing Tang

Journal of the South Carolina Academy of Science

Infectious diseases caused by drug-resistant microorganisms have become a major contributor for human morbidity and mortality. To overcome such threats, we have developed various antimicrobial agents using natural product derivatives and metallopolymers. Abundant biomass such as resin acids can be utilized to prepare cationic polymers for inhibiting a variety of bacteria. These polymers have been used in solution as well as surfaces as antimicrobial materials with low cytotoxicity. In addition, a class of charged metallopolymers have been developed to kill superbugs such as MRSA.

Data-Driven Identification Of Potential Zika Virus Vectors, Michelle V. Evans, Tad Dallas, Barbara A. Han, Courtney C. Murdock, John M. Drake

Faculty Publications

Zika is an emerging virus whose rapid spread is of great public health concern. Knowledge about transmission remains incomplete, especially concerning potential transmission in geographic areas in which it has not yet been introduced. To identify unknown vectors of Zika, we developed a data-driven model linking vector species and the Zika virus via vector-virus trait combinations that confer a propensity toward associations in an ecological network connecting flaviviruses and their mosquito vectors. Our model predicts that thirty-five species may be able to transmit the virus, seven of which are found in the continental United States, including Culex quinquefasciatus and Cx. …

Hair Measurements Of Cortisol, Dhea, And Dhea To Cortisol Ratio As Biomarkers Of Chronic Stress Among People Living With Hiv In China: Known-Group Validation, Shan Qiao Ph.D., Xiaoming Li, Samuele Zilioli, Zheng Chen, Huihua Deng, Juxian Pan, Weigui Guo

Faculty Publications

Background

Existing literature suggests that endocrine measures, including the steroid hormones of cortisol and Dehydroepiandrosterone (DHEA), as well as the DHEA to cortisol ratio in the human hair can be used as promising biomarkers of chronic stress among humans. However, data are limited regarding the validity of these measures as biomarkers of chronic stress among people living with HIV (PLWH), whose endocrine system or hypothalamic pituitary adrenal (HPA) axis may be affected by HIV infection and/or antiretroviral therapy (ART) medications.

Method

Using hair sample data and self-reported survey from 60 PLWH in China, we examined the validity of three endocrine …
