Using Prescription Drug Monitoring Data To Inform Population Level Analysis Of Opioid Analgesic Utilization, Huong T. T. Luu

Theses and Dissertations--Epidemiology and Biostatistics

Increased opioid analgesic (OA) prescribing has been associated with increased risk of prescription opioid diversion, misuse, and abuse. States established prescription drug monitoring programs (PDMPs) to collect and analyze electronic records for dispensed controlled substances to reduce prescription drug abuse and diversion. PDMP data can be used by prescribers for tracking patient’s history of controlled substance prescribing to inform clinical decisions.

The studies in this dissertation are focused on the less utilized potential of the PDMP data to enhance public health surveillance to monitor OA prescribing and co-prescribing and association with opioid overdose mortality and morbidity. Longitudinal analysis of OA …

Association Between Dispensing Channel And Chronic Obstructive Pulmonary Disorder Exacerbations Among Medicare Beneficiaries, April S. Prather

Theses and Dissertations--Pharmacy

Elderly patients with chronic obstructive pulmonary disease may be at increased risk of exacerbation due to physical and cognitive deficits that make proper inhaled medication adherence more difficult despite consistent medication access. This retrospective study utilized administrative medical and pharmacy claims data to examine the likelihood of having a COPD exacerbation requiring acute medical care by means of an emergency room visit or hospitalization in elderly patients receiving maintenance COPD medications from mail order and retail pharmacies. It was hypothesized that mail order patients would be more likely to experience exacerbations despite differences in medication access when compared to retail …

Dual Lox/Cox Inhibition: A Novel Strategy To Prevent Neurovascular Leakage In Epilepsy, Brent S. Sokola

Theses and Dissertations--Pharmacy

Epilepsy affects 3.4 million patients in the USA and is characterized by recurring seizures. The blood-brain barrier is leaky in epilepsy and may contribute to seizure progression but the mechanisms which cause this leakage are not fully understood. We hypothesized that seizures trigger LOX- and COX-mediated blood-brain barrier leakage and that dual LOX/COX inhibition prevents barrier leakage in vivo. To test this hypothesis, we administered either the dual LOX/COX inhibitor licofelone or a combination of the 5-LOX inhibitor zileuton and the COX-2 inhibitor celecoxib to rats that experienced status epilepticus (SE). Serum and brain capillaries were isolated 48 hours …

Investigating The Role Of Prescription Drug Monitoring Programs In Reducing Rates Of Opioid-Related Poisonings, Nathan James Pauly

Theses and Dissertations--Pharmacy

The United States is in the midst of an opioid epidemic. In addition to other system level interventions, almost all states have responded to the crisis by implementing prescription drug monitoring programs (PDMPs). PDMPs are state-level interventions that track the dispensing of Controlled Substances. Data generated at the time of medication dispensing is uploaded to a central data server that may be used to assist in identifying drug diversion, medication misuse, or potentially aberrant prescribing practices.

Prior studies assessing the impact of PDMPs on trends in opioid-related morbidity have often failed to take into account the wide heterogeneity of program …

The Impact Of Bioactive Phytosterol, Stigmasterol, On Cholesterol Elimination Pathways In Mice, Hannah C. Lifsey

Theses and Dissertations--Pharmacy

Despite advances in healthcare, cardiovascular disease (CVD) remains the leading cause of death in the United States. Elevated levels of plasma cholesterol are highly predictive of CVD and stroke and are the principal driver of atherosclerosis. Unfortunately, current cholesterol lowering agents, such as statins, are not known to reverse atherosclerotic disease once it has been established. In preclinical models, agonists of nuclear receptor, LXR, have been shown to reduce and reverse atherosclerosis. Phytosterols are bioactive non-cholesterol sterols that act as LXR agonists and regulate cholesterol metabolism and transport. We hypothesize that stigmasterol would act as an LXR agonist and alter …

Discovery Of Novel Muraymycin Antibiotics And Insight Into The Biosynthetic Pathway, Zheng Cui

Theses and Dissertations--Pharmacy

New antibiotics with novel targets or mechanisms of action are needed to counter the steady emergence of bacterial pathogens that are resistant to antibiotics used in the clinic. MraY, a promising novel target for antibiotic development, initiates the lipid cycle for the biosynthesis of peptidoglycan cell wall, which is essential for the survival of most, if-not-all, bacteria. MraY is an enzyme that catalyzes the transfer and attachment of phospho-MurNAc-pentapeptide to a lipid carrier, undecaprenylphosphate. Muraymycins are recently discovered lipopeptidyl nucleoside antibiotics that exhibit remarkable antibiotic activity against Gram-positive as well as Gram-negative bacteria by inhibiting MraY. We conducted a thorough …

Understanding The Thermodynamics And Oral Absorption Potential Of Pharmaceutical Amorphous Solid Dispersions, Nico Setiawan

Theses and Dissertations--Pharmacy

Supersaturating drug delivery systems, such as amorphous solid dispersions (ASDs), have been used extensively to elevate the apparent solubility and oral bioavailability of poorly water-soluble drugs. However, despite the numerous examples of success in increasing solubility and oral bioavailability using ASDs, physical stability challenges remain as formulators seek to employ high drug loading for cost reduction and improved patient compliance. Therefore, stability in both the solid and solution state must be considered for ASDs to be successful. In the solid state, the drug must remain amorphous in the solid matrix throughout the shelf life of the product. Although excipients, such …

Discovery Of New Antimicrobial Options And Evaluation Of Aminoglycoside Resistance Enzyme-Associated Resistance Epidemic, Selina Y. L. Holbrook

Theses and Dissertations--Pharmacy

The extensive and sometimes incorrect and noncompliant use of various types of antimicrobial agents has accelerated the development of antimicrobial resistance (AMR). In fact, AMR has become one of the greatest global threat to human health in this era. The broad-spectrum antibiotics aminoglycosides (AGs) display excellent potency against most Gram-negative bacteria, mycobacteria, and some Gram-positive bacteria, such as Staphylococcus aureus. The AG antibiotics amikacin, gentamicin, kanamycin, and tobramycin are still commonly prescribed in the U.S.A. for the treatment of serious infections. Unfortunately, bacteria evolve to acquire resistance to AGs via four different mechanisms: i) changing in membrane permeability to …

Development And Preclinical Evaluation Of Long-Lasting Cocaine Hydrolases For Cocaine Overdose And Cocaine Use Disorder Treatment, Ting Zhang

Theses and Dissertations--Pharmacy

Cocaine is a plant-based illicit drug commonly involved in substance use disorder. Although cocaine overdose and cocaine use disorders cause adverse health consequences to individuals and the economic burden on their family and society, there are no FDA (Food and Drug Administration) approved medications for treatment. Recently, it has been recognized that delivery of cocaine hydrolase (CocH) is a promising therapeutic strategy. Human butyrylcholinesterase (hBChE), the primary enzyme involved in cocaine metabolism in human, have advantages over other candidates for the development of CocH. Previous studies in our laboratory have designed and characterized hBChE mutants that have ~4,000-fold improved catalytic …

Using The Qbest Equation To Evaluate Ellagic Acid Safety Data: Generating A Qnoael With Confidence Levels From Disparate Literature, Cynthia Rose Dickerson

Theses and Dissertations--Pharmacy

QBEST, a novel statistical method, can be applied to the problem of estimating the No Observed Adverse Effect Level (NOAEL or QNOAEL) of a New Molecular Entity (NME) in order to anticipate a safe starting dose for beginning clinical trials. The NOAEL from QBEST (called the QNOAEL) can be calculated using multiple disparate studies in the literature and/or from the lab. The QNOAEL is similar in some ways to the Benchmark Dose Method (BMD) used widely in toxicological research, but is superior to the BMD in some ways. The QNOAEL simulation generates an intuitive curve that is comparable to the …

Investigations Of Interleukin-1 Alpha As A Novel Stroke Therapy In Experimental Ischemic Stroke, Kathleen Elizabeth Salmeron

Theses and Dissertations--Neuroscience

Stroke is a leading cause of death and disability worldwide. Although rapid recognition and prompt treatment have dropped mortality rates, most stroke survivors are left with permanent disability. Approximately 87% of all strokes result from the thromboembolic occlusion of the cerebrovasculature (ischemic strokes). Potential stroke therapeutics have included anti-inflammatory drugs, as well as many other targets with the goal of mitigating the acute and chronic inflammatory responses typically seen in an ischemic stroke. While these approaches have had great success in preclinical studies, their clinical translation has been less successful. Master inflammatory cytokines, such as IL-1, are of particular interest. …

Understanding Haitian Women’S Health Care In Immokalee, Florida, Usa, Michele Leigh Flippo Bolduc

Theses and Dissertations--Geography

This social science research project takes a critical approach to understanding the health of a population by using the health care system as an entry point through which we can see how large-scale social processes produce a particular health care landscape in the rural, im/migrant farmworker community of Immokalee, Florida, USA. Using a multi-scalar analysis of health care, I investigate how anti-immigrant legislation and neoliberal economics influence the experience of health care for health care providers and Haitian im/migrant women navigating these processes. First, I argue that anti-immigrant and pro-market discourses have been successful in limiting the accessibility to health …

Mobility Boost: A Quality Improvement Project To Bridge A Gap In Care For Hospitalized Adults, Audrey M. Johnson

Theses and Dissertations--Rehabilitation Sciences

Early mobility quality improvement (QI) projects are leading the charge to shift the prevailing culture in acute care from a culture of immobility to a culture of mobility. Low mobility and hospital acquired functional decline is a persistent problem, especially for older adults, often leading to increased post acute care costs, increased risk of hospital readmission and increased mortality. Transition of care programs designed to improve care transitions and prevent hospital readmission exist but fail to include rehabilitation professionals or to adequately consider patient functional status during hospitalization. The goal of this research was to implement and evaluate an early …

Role Of Oxidized Extracellular Vesicles As Early Biomarkers And Inflammatory Mediators In Chemotherapy-Induced Normal Tissue Injury, Chontida Yarana

Theses and Dissertations--Toxicology and Cancer Biology

Significant advances in the efficacy of cancer therapy have been accompanied by an escalation of side effects that result from therapy-induced injury to normal tissues. Patients with high grade cancer or metastasis are often treated with chemotherapy, 50% of which are associated with reactive oxygen species generation and cellular oxidative stress. Heart is the normal tissue most susceptible to chemotherapy-induced oxidative stress and heart disease is the most common leading cause of death in cancer survivors. However, early and sensitive biomarkers to identify heart disease are still lacking. Extracellular vesicles (EVs) are released from cells during oxidative stress and send …

Quitting Together: Formative Research To Develop A Social Marketing Plan For Smoking Cessation Among Women In A Residential Treatment Facility For Substance Abuse Recovery, August D. Anderson

Theses and Dissertations--Communication

Both smoking addiction and illicit substance abuse are prevalent issues in the United States today. Furthermore, these are issues that have significant impact on women’s health and mental state. Despite research that shows that smoking cessation coupled with substance abuse recovery can decrease likelihood of relapse post-recovery, few substance abuse recovery facilities today offer smoking cessation programming options. To address the issue of smoking addiction on top of substance abuse recovery, formative research was conducted through this study to determine the underlying causes of smoking habits coupled with recovery efforts and the attitudes. Through focus group sessions with women in …
