Evaluation Of Therapeutics For An Enterovirus 71 Infection In An Ag129 Mouse Model, Christopher Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Discovered in 1969 in California, enterovirus 71 (EV-71) is a serious cause of disease in young children. It is one of the major causative agents of hand, food, and mouth disease (HFMD), and can produce neurological complications, such as meningitis, encephalitis, and an acute flaccid paralysis. For serious cases, the fatality rate can be up to 26%, almost exclusively in young children.

While the virus was initially discovered in the United States, it was soon detected in the Eastern hemisphere, causing outbreaks in Europe and Asia. The largest outbreak occurred in Taiwan in 2008, with approximately 490,000 cases and 128 …

Limiting Antibiotic Use In Acute Sinusitis: Partly A Matter Of Vocabulary?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In his issue introduction, the editor-in-chief of Journal of Patient-Centered Research and Reviews comments on an included article that describes the successful use of an electronic medical record best practice alert to reduce the rate of antibiotic prescription for acute sinusitis. Various methods previously tried to improve antibiotic stewardship in this illness are briefly reviewed. Borrowing on the model of acute bronchitis, it is suggested that a change in conveyed diagnostic vocabulary to “sinus cold” when describing acute sinusitis may help limit antibiotics for this predominantly viral infection.

Using Clinical Decision Support Within The Electronic Health Record To Reduce Incorrect Prescribing For Acute Sinusitis, Regina Ginzburg, Justin J. Conway, Eve Waltermaurer, Wendy Song, Samantha P. Jellinek-Cohen

Journal of Patient-Centered Research and Reviews

Purpose: Acute sinusitis has viral etiology in more than 90% of cases, but antibiotics are prescribed for more than 80% of adults in the United States. While applications of computer-assisted guidelines have been found effective in reducing inaccurate prescribing for acute respiratory infections, there is a paucity of research focused specifically on the utilization of electronic best practice alerts (BPA) in improving treatment for acute sinusitis.

Methods: This observational cohort study examined prescribing behavior for sinusitis at a single Federally Qualified Health Center 1 year prior and during the first year of implementation of a BPA in the electronic health …

Evaluation Of Oncolytic And Immunomodulatory Potential Of The Hsv-1 Live-Attenuated Vaccine Strain Vc2 In An Immunocompetent Murine Melanoma Model, Natalie Wall Fowlkes

LSU Doctoral Dissertations

Melanoma accounts for 90% of skin cancer-related deaths in humans. Treatment options for metastatic melanoma in people is very limited. Melanoma is considered to be an immunogenic tumor, spurring interest in development of immunotherapies for the treatment of metastatic melanoma. Oncolytic virotherapy has been widely investigated. The first ever oncolytic virotherapy to receive FDA-approval is an HSV-1-based virus (Talimogene Laherperavec (T-Vec) or Imlygic) containing a transgene for human GM-CSF to enhance anti-tumor immune responses after injection. Durable response rate in human patients was only 16% despite impressive efficacy in anti-tumor effects in vitro and in murine tumor models. Novel viruses …

Type 2 Bovine Viral Diarrhea Virus NPro Suppresses Type I Interferon Pathway Signaling In Bovine Cells And Augments Bovine Respiratory Syncytial Virus Replication, Abdulrahman Abdulaziz A. Alkheraif

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine viral diarrhea virus (BVDV) and bovine respiratory syncytial virus (BRSV) infections contribute to the bovine respiratory disease complex (BRDC), which is a multi-factorial disorder involving co-infections of viruses and bacteria including mycoplasma. BRDC causes great economic losses to the United States feedlot industry. BVDV infection induces immunosuppression in infected animals. BVDV N^pro binds and degrades the transcription factor interferon regulatory factor-3 (IRF-3) and effectively blocks type I interferon (type I IFN) expression in host cells. BRSV nonstructural proteins, NS1 and NS2, block activation of IRF-3. In calves, concurrent infection with BVDV and BRSV resulted in more severe clinical …

Human Papillomavirus: The Influence Of Prevention And Vaccination, Lacey N. Russell

Kentucky Journal of Undergraduate Scholarship

Human Papillomavirus infections (HPV) are the most common sexually transmitted diseases in the United States. Of cancers in parts of the body where HPV is often discovered about 80% originated from an HPV infection. Despite this knowledge and the effectiveness of the HPV vaccine, vaccination by both genders in Kentucky and on a national scale remains highly underutilized. As a result, preventable incidence and mortality rates from HPV-related illness are elevated. Health care delivery factors such as increased vaccination and preventative care, insurance coverage, and accessible rural health care are necessary for HPV prevention and promotion of holistic health. The …

Biological Sciences Faculty Publications

Dengue virus (DENV) is a mosquito-borne flavivirus that causes dengue fever in humans, worldwide. Using in vitro cell lines derived from Aedes albopictus and Aedes aegypti, the primary vectors of DENV, we report that DENV2/DENV3-infected cells secrete extracellular vesicles (EVs), including exosomes, containing infectious viral RNA and proteins. A full-length DENV2 genome, detected in arthropod EVs, was infectious to naïve mosquito and mammalian cells, including human-skin keratinocytes and blood endothelial cells. Cryo-electron microscopy showed mosquito EVs with a size range from 30 to 250 nm. Treatments with RNase A, Triton X-100, and 4G2 antibody-bead binding assays showed that infectious …

South Africa, Hiv/Aids, And Education, Katie Roberts

Master's Projects and Capstones

Human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) are huge problems in South Africa. HIV is a disease that attacks a person’s immune system and, if not properly treated, can lead to AIDS. While there is a treatment—antiretroviral drugs—HIV remains a highly stigmatized disease. This field project focuses on reducing stigma so people are unafraid to get tested or seek treatment. Created to benefit both teachers and their learners, the goal of this mathematics curriculum (consisting of 12 lesson plans and worksheets) is to begin HIV/AIDS awareness in school so accurate information is learned and stigma is reduced. The …

Background

Being food insecure is generally defined as the limited or uncertain availability of safe and nutritious foods and is linked to poor nutrition and fully progressed diet-sensitive chronic diseases. However, little is known about the association between food insecurity and pre-clinical disease such as pre-hypertension and pre-diabetes. This study sought to examine the associations between food insecurity and pre-clinical disease among a racially/ethnically diverse population of women.

Methods

Using data from 2007-2010 NHANES, we examined associations between food security and pre-clinical disease among women 18-65 years. Chi-square tests were used to examine differences in demographic variables. Bivariate and multivariable …

Ebola: Africa, James Goodwin

Global Issues in Public Health

In this paper, I talk about the Ebola Hemorrhagic Fever. Ebola is a rare virus that spreads through the immune system and can be fatal. Ebola is a pathogen from Africa, specifically West Africa. There has been almost 32,000 cases since 1976. Symptoms include, Fever, Headache, Muscle pain, Fatigue, Diarrhea, Vomiting, Stomach pain, and Bleeding/Bruising. Transmission happens during close or direct contact. World Health Organization has been making efforts to handle outbreaks such as the outbreak in 2014. World Health Organization mobilized and set up relief efforts. Education is a key idea for my thoughts on how we can intervene …

The Behavioral Response Of Mosquitoes To Different Snake Odors, Caitlyn E. Hicks

Honors College Theses

Due to it causing high mortality rates, Eastern Equine Encephalitis (EEEV) is considered to be one of the most medically important encephalitic viruses in the Eastern United States. In order to be able to control the transmission of this virus, understanding of vector behavior and feeding preferences is necessary. In this study, the response of Culex nigripalpus to different snake skin odors was tested to determine if this species of mosquito responded to particular snake species. Culex nigripalpus showed the greatest response to Copperhead (Agkistrodon contortrix) and Cottonmouth (A. piscivorus) snakes, as compared to other venomous …

Hiv/Aids: Ethiopia, Luzana Girmay

Global Issues in Public Health

AIDS is a public health problem that affects the immune system of the human body which results in people getting affected by other diseases easily. This syndrome is caused by a pathogen known as HIV (Human Immunodeficiency Virus). There are numerous means of transmissions; some of which are drug use, contact with fluids like blood, semen, rectal fluids, and breast milk but the main mode of transmission is through sexual intercourse. The symptoms of HIV/AIDS include fever, rash, and night sweats. The highest number of HIV positive people are located in Africa, which is about 23.8 million people. Of those …

Tat Controls Transcriptional Persistence Of Unintegrated Hiv Genome In Primary Human Macrophages., Beatrix Meltzer, Deemah Dabbagh, Jia Guo, Fatah Kashanchi, Mudit Tyagi, Yuntao Wu

Medicine Faculty Publications

In HIV infected macrophages, a large population of viral genomes persists as the unintegrated form (uDNA) that is transcriptionally active. However, how this transcriptional activity is controlled remains unclear. In this report, we investigated whether Tat, the viral transactivator of transcription, is involved in uDNA transcription. We demonstrate that de novo Tat activity is generated from uDNA, and this uDNA-derived Tat (uTat) transactivates the uDNA LTR. In addition, uTat is required for the transcriptional persistence of uDNA that is assembled into repressive episomal minichromatin. In the absence of uTat, uDNA minichromatin is gradually silenced, but remains highly inducible by HDAC …

Enhanced Production Of Pro-Il-1Βeta Contributes To Immunopathology During The Coinfection Of Influenza A Virus And Streptococcus Pneumoniae, Angeline E. Rodriguez

Graduate Theses/Dissertations

Viral bacterial coinfections are known to cause severe pneumonia, especially in the elderly and in pediatric patients. Antibiotics like β-Lactams kill the bacteria but fail to improve symptoms suggesting a faulty immune system may play an important role in the disease. Interleukin-1β (IL-1β) is an important immune signaling cytokine responsible for inflammation. It exists as an inactive precursor that can be activated by caspase-1 containing inflammasomes (multi-protein complex). Influenza A virus (IAV) and Streptococcus pneumoniae (S. pneumoniae) activate the inflammasome through the NOD-like receptor protein NLRP3 and/or AIM2. Previous reports in mice indicate that IL-1β levels are dramatically …

Herpes Zoster Patient Education: A Coloring Book Approach, Sophia Charuhas

Senior Honors Theses

Shingles, the disease caused by the herpes zoster virus, is a widespread and widely misunderstood illness in the United States. It is preventable, but many at-risk patients do not know what measures they may take to prevent it. Clear communication from physician to patient is crucial for patient understanding of diseases. Many patient education materials on herpes zoster currently available are often unused. It is therefore beneficial to public health to disseminate new mediums of medical communication, and one way of accomplishing this is through adult coloring books. The pathophysiology of herpes zoster virus is here explored and the idea …

Kshv Induces Immunoglobulin Rearrangements In Mature B Lymphocytes, Jennifer Totonchy, Jessica M. Osborn, Amy Chadburn, Ramina Nabiee, Lissenya Argueta, Geoffrey Mikita, Ethel Cesarman

Pharmacy Faculty Articles and Research

Kaposi sarcoma herpesvirus (KSHV/HHV-8) is a B cell tropic human pathogen, which is present in vivo in monotypic immunoglobulin λ (Igλ) light chain but polyclonal B cells. In the current study, we use cell sorting to infect specific B cell lineages from human tonsil specimens in order to examine the immunophenotypic alterations associated with KSHV infection. We describe IL-6 dependent maturation of naïve B lymphocytes in response to KSHV infection and determine that the Igλ monotypic bias of KSHV infection in vivo is due to viral induction of BCR revision. Infection of immunoglobulin κ (Igκ) naïve B cells induces expression …
