Role Of Viral And Host Factors In Influenza Virus Mediated Inhibition Of Interleukin-23, Ashish Tiwari

Theses and Dissertations--Veterinary Science

Influenza virus is one of the major respiratory pathogens of humans as well as animals, including equines. There is an increasing evidence that bacterial infections are the most common cause of the death during influenza. In horses also, secondary bacterial pneumonia can lead to death, and surviving horses may take up to six months for the complete recovery resulting in heavy economic loss to the equine industry. Interleukin (IL)-23 mediated innate immune response has been shown to protect the host from various respiratory bacterial infections. However, studies to investigate the role of host and viral factors in the regulation of …

Examination Of The Snsag Surface Antigen Gene Family In Sarcocystis Neurona, Ablesh Gautam

Theses and Dissertations--Veterinary Science

Sarcocystis neurona is a protozoan parasite that causes the serious neurologic disease equine protozoal myeloencephalitis (EPM). The life cycle of S. neurona progresses through multiple developmental stages that differ morphologically and molecularly. The S. neurona merozoite surface is covered by multiple related proteins, which are orthologous to the surface antigen (SAG) gene family of Toxoplasma gondii. The SAG surface antigens in T. gondii and another related parasite Neospora caninum are life cycle stage-specific and seem necessary for parasite transmission and persistence of infection. The present research was conducted to explore the gene family of SnSAGs in S. …

Attitudes Toward Assisted Reproductive Technology: The Effects Of Gender, Relationship Status, Age, And Sexual Orientation, Brigitte A. Dooley

Theses and Dissertations--Family Sciences

Reproductive technology has extended procreative options to infertile, subfertile, unpartnered, and same-sex-partnered individuals, but this technology is sometimes used in circumstances that may be deemed unreasonable or inappropriate by some people. The purpose of this study was to assess the effects of five contextual variables—gender, relationship status, age, and sexual orientation of the individual or couple seeking reproductive assistance, as well as the source of gametes—on attitudes toward the procurement of reproductive services. A multiple-segment factorial vignette was administered to a sample of 257 reproductive-aged respondents. Results indicate that ART is generally viewed as an acceptable procedure by reproductive aged …

The Patient Protection And Affordable Care Act’S Effects On Patterns Of Coverage In A Ryan White Funded Hiv Clinic: What Are The Implications For The Bluegrass Care Clinic?, Jacqueline Wagner Mccuddy

MPA/MPP/MPFM Capstone Projects

The Ryan White CARE Act of 1991 implemented a federal grant program to help individuals in the US with HIV/AIDS get access to healthcare and diminish barriers to care. Since its enactment, there have been many changes in the environment of HIV/AIDS, including a demographic shift in those most affected by the disease and a growing number of new infections, the introduction of Antiretroviral therapy, and most recently, the implementation of the Patient Protection and Affordable Care Act (PPACA).

The PPACA is expected to have a positive effect on patients with HIV in the US by increasing access to care, …

Utilization Of The Kentucky Aids Drug Assistance Program Versus Kentucky Medicaid Using Medication Possession Ratio: Policy Implications For Public Program, Jenna Parrett

MPA/MPP/MPFM Capstone Projects

Uninsured and underinsured people living with Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) are able to utilize federally funded AIDS Drug Assistance Programs (ADAPs) to cover the price of their HIV-related medications. In Kentucky, this program also provides support services through social workers, a dedicated pharmacist, and medications by mail order. With the Affordable Care Act, many patients previously covered by the Kentucky AIDS Drug Assistance Program (KADAP) will be newly eligible for Medicaid and will no longer receive services through KADAP. There is concern that people in this situation will be at a disadvantage without these services and, in …

Screening For Sepsis: A Key Strategy For Early Identification And Management Of Septic Patients, Amy P. Fisher

DNP Projects

Background: Sepsis, defined as a systemic inflammatory response to infection, is a life-threatening medical condition that rapidly progresses from severe sepsis (characterized by signs of organ dysfunction) to septic shock with fluid-refractory hypotension. Adherence to the Surviving Sepsis Campaign guidelines for the management of severe sepsis and septic shock have been associated with improved delivery of care and reduced mortality. Delays in recognition of sepsis has been identified as a barrier to achieving early goal-directed therapy targets.

Purpose: To determine if a sepsis screening protocol could facilitate earlier identification of patients with sepsis

Methods: A retrospective medical record review was …

Stability Studies Of Membrane Proteins, Cui Ye

Theses and Dissertations--Chemistry

The World Health Organization has identified antimicrobial resistance as one of the top three threats to human health. Gram-negative bacteria such as Escherichia coli are intrinsically more resistant to antimicrobials. There are very few drugs either on the market or in the pharmaceutical pipeline targeting Gram-negative pathogens. Two mechanisms, the protection of the outer membrane and the active efflux by the multidrug transporters, play important roles in conferring multidrug resistance to Gram-negative bacteria. My work focuses on two main directions, each aligning with one of the known multidrug resistance mechanisms.

The first direction of my research is in the area …

Evidence For Finely-Regulated Asynchronous Growth Of Toxoplasma Gondii Cysts Based On Data-Driven Model Selection, Adam M. Sullivan, Xiaopeng Zhao, Yasuhiro Suzuki, Eri Ochiai, Stephen Crutcher, Michael A. Gilchrist

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Toxoplasma gondii establishes a chronic infection by forming cysts preferentially in the brain. This chronic infection is one of the most common parasitic infections in humans and can be reactivated to develop life-threatening toxoplasmic encephalitis in immunocompromised patients. Host-pathogen interactions during the chronic infection include growth of the cysts and their removal by both natural rupture and elimination by the immune system. Analyzing these interactions is important for understanding the pathogenesis of this common infection. We developed a differential equation framework of cyst growth and employed Akaike Information Criteria (AIC) to determine the growth and removal functions that best describe …

Accreditation And Standardization In Local Public Health, Glen P. Mays

Health Management and Policy Presentations

Reducing harmful, wasteful, and inequitable variation in public health delivery is a central objective for administrative and policy decision-makers in public health, and is embedded in the national accreditation movement. The challenge lies in accomplishing this objective while preserving the benefits of customization in public health delivery that accrue through tailoring and targeting of resources to unique community needs and risks. Public health services and systems research (PHSSR) can help determine the optimal balance between standardization and customization in public health delivery.

Phosphorylation Of Calcineurin At A Novel Serine-Proline Rich Region Orchestrates Hyphal Growth And Virulence In Aspergillus Fumigatus, Praveen R. Juvvadi, Christopher Gehrke, Jarrod R. Fortwendel, Frédéric Lamoth, Erik J. Soderblom, Erik C. Cook, Michael A. Hast, Yohannes G. Asfaw, M. Arthur Moseley, Trevor P. Creamer, William J. Steinbach

Molecular and Cellular Biochemistry Faculty Publications

The fungus Aspergillus fumigatus is a leading infectious killer in immunocompromised patients. Calcineurin, a calmodulin (CaM)-dependent protein phosphatase comprised of calcineurin A (CnaA) and calcineurin B (CnaB) subunits, localizes at the hyphal tips and septa to direct A. fumigatus invasion and virulence. Here we identified a novel serine-proline rich region (SPRR) located between two conserved CnaA domains, the CnaB-binding helix and the CaM-binding domain, that is evolutionarily conserved and unique to filamentous fungi and also completely absent in human calcineurin. Phosphopeptide enrichment and tandem mass spectrometry revealed the phosphorylation of A. fumigatus CnaA in vivo at four clustered serine residues …

Diffusion Of Innovation Across A National Local Health Department Network: A Simulation Approach To Policy Development Using Agent-Based Modeling, Mark Orr, Jacqueline Merrill

Frontiers in Public Health Services and Systems Research

The network that local health officials use to communicate about professional issues is sparsely connected, which may limit the spread of innovative practices. We used agent-based simulation modeling to find out if a policy to promote more connections improved the network’s capability to diffuse innovation. We found that unanticipated effects could result, depending on the requirements of the policy and the proportion of health officials involved. With carefully crafted assumptions and reliable data it is possible to untangle complex processes using simulation modeling. The results represent how the world might actually work which may provide useful decision support for policymakers …

Population Cancer Risks Associated With Coal Mining: A Systematic Review, Wiley D. Jenkins, W. Jay Christian, Georgia Mueller, K. Thomas Robbins

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this regard.

METHODS: We performed a systematic review of English-language manuscripts published since 1980 to determine if coal mining exposure was associated with increased cancer risk (incidence and mortality).

RESULTS: Of 34 studies identified, 27 studied coal mining as an occupational exposure …

Envelope Determinants Of Equine Lentiviral Vaccine Protection, Jodi K. Craigo, Corin Ezzelarab, Sheila J. Cook, Chong Liu, David W. Horohov, Charles J. Issel, Ronald C. Montelaro

Veterinary Science Faculty Publications

Lentiviral envelope (Env) antigenic variation and associated immune evasion present major obstacles to vaccine development. The concept that Env is a critical determinant for vaccine efficacy is well accepted, however defined correlates of protection associated with Env variation have yet to be determined. We reported an attenuated equine infectious anemia virus (EIAV) vaccine study that directly examined the effect of lentiviral Env sequence variation on vaccine efficacy. The study identified a significant, inverse, linear correlation between vaccine efficacy and increasing divergence of the challenge virus Env gp90 protein compared to the vaccine virus gp90. The report demonstrated approximately 100% protection …

Harnessing The Power Of Public Health Systems For Injury Prevention & Control, Glen P. Mays

Health Management and Policy Presentations

Efforts to improve population health hinge on a vast yet diffuse constellation of government agencies, health care providers, and community organizations that assume responsibilities in implementing prevention programs and policies across the U.S. Realizing the full health and economic benefits of injury prevention and control initiatives requires mobilizing and managing these complex and heterogeneous public health delivery systems. This session will explore the emerging science of public health delivery systems and what it tells us about improving injury prevention and control amid policy and economic change.

Public Health Delivery Systems And Population Health, Glen P. Mays

Health Management and Policy Presentations

Despite high overall health expenditures, the U.S. continues to fall behind other high-income countries on many measures of population health. While health care delivery systems are now studied intensively for solutions to U.S. cost and quality problems, the nation's delivery systems for public health programs and policies are only now becoming the subject of rigorous empirical study. This presentation examines recent studies of public health delivery systems and important directions for future inquiry.

Significant Sequelae After Bacterial Meningitis In Niger: A Cohort Study, Jean-François Jusot, Zilahatou Tohon, Abdoul Aziz Yazi, Jean-Marc Collard

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Beside high mortality, acute bacterial meningitis may lead to a high frequency of neuropsychological sequelae. The Sahelian countries belonging to the meningitis belt experience approximately 50% of the meningitis cases occurring in the world. Studies in Africa have shown that N. meningitidis could cause hearing loss in up to 30% of the cases, exceeding sometimes measles. The situation is similar in Niger which experiences yearly meningitis epidemics and where rehabilitation wards are rare and hearing aids remain unaffordable. The aim of this study was to estimate the frequency of neuropsychological sequelae after acute bacterial meningitis in four of the …
