In-Vitro Time-Kill Assays And Semi-Mechanistic Pharmacokinetic-Pharmacodynamic Modeling Of A Beta-Lactam Antibiotic Combination Against Enterococcus Faecalis: Optimizing Dosing Regimens For The Geriatric Population, Zeel Saumin Shah

Selected Full-Text Dissertations 2020-

Pharmacokinetic-pharmacodynamic (PKPD) modeling and simulation have emerged as pivotal tools in drug development and usage. Such models characterize typical trends in data and quantify the variability in relationships among dose, concentration, and desired effects. For antibacterial applications, models characterizing bacterial growth and antibiotic-induced bacterial killing offer insight into interactions between antibiotics, bacteria, and the host. Simulations from these models predict outcomes for untested scenarios, refine study designs, and optimize dosing regimens.

Enterococcus faecalis, a significant opportunistic bacterial pathogen with increasing clinical relevance, is commonly found in the gastrointestinal tract but can lead to severe infection, such as endocarditis. Treatments for …

An Ex-Vivo Investigation Of The Effect Of Skin Conditioning With Formulation Vehicles On The Dermal Disposition Of Diphenhydramine Perfused Directly Into The Dermis, Nasim Rezvani Haghighi Shirazi

Selected Full-Text Dissertations 2020-

It is well known that the composition/excipients of a topical dermatological drug product (TDDP) affect the permeation of an active pharmaceutical ingredient (API) through the skin. While it is generally accepted that the vehicle mostly modulates the release of the API from the product, little is known whether the vehicle might also influence the kinetics of the API within the skin itself. In one attempt to answer this question, we developed an ex-vivo model using pig ear and a retrodialysis/microdialysis technique to deliver the API directly into dermis and measure the API dermal pharmacokinetics (dPK). We compared the dPK of …

Pediatric Vaccination Adherence: Enhancing Compliance Among First-Generation Asian American Parents, Katelyn Leong

Nursing | Senior Theses

Background: Vaccine adherence in the pediatric population refers to receiving vaccines as per the recommended schedule, which significantly reduces vaccine-preventable diseases and enhances community immunity. Vaccine hesitancy, driven by concerns such as safety, misinformation, or cultural beliefs can affect adherence. National coverage of state-mandated vaccines among kindergarteners declined from 95% to around 93% between 2019 and 2022, varying across different vaccines. Objective: This research proposal’s focus is to determine if an educational intervention targeting first-generation Asian Americans, who have adopted their immigrant parents' misinformation about vaccines, will effectively increase vaccination rates among their children. The study aims to assess the …

Increasing The Efficacy Of Actinomycin D With Resveratrol In Aerodigestive Tract Cancers, Lukmon Morenikeji Raji

Theses, Dissertations and Capstones

Chemotherapy poses a significant challenge for cancer patients due to drug-associated toxicity, which often results from their effects on both healthy (normal) and cancerous cells. While various options aim to reduce toxicity and optimize beneficial effects, a comprehensive solution remains elusive. Cyclotherapy is one such approach developed to protect normal cells from the toxic effects of chemotherapy drugs. The basic principle underlying cyclotherapy is p53- dependent cell cycle arrest of normal cells while killing cancer cells via a p53-independent mechanism using a second drug. In our research, we investigated the inhibitory effects of a combination of two low-dose anticancer drugs, …

Effective Risk-Based Decision Making In Quality Risk Management, Valerie Mulholland

Dissertations

Patients expect safe, effective, high-quality medicines that are available when needed. Meeting these expectations is increasingly challenging in a global pharmaceutical supply chain, as evidenced by persistent product quality and supply issues. A key contributory factor to these issues is disruptions in manufacturing operations, which in turn are often caused by a hesitancy to change and to continuously improve approved processes. Regulatory agencies repeatedly indicate that they will consider increased autonomy for post-approval changes, if pharmaceutical manufacturing operations can demonstrate the effectiveness of Quality Risk Management (QRM) within the Pharmaceutical Quality System (PQS). Thus, the question was posed by Dr …

Synthesis Of Leishmania Spp Antigens For The Development Of Vaccine Candidates, Dipesh Budhathoki

Theses and Dissertations

Leishmaniasis is a neglected tropical disease caused by the protozoan parasite of the genus Leishmania. Presently no vaccine against Leishmaniasis is available, so there is a need for new anti-leishmanial treatments, including an effective preventive vaccine. We focus on developing vaccine candidates based on leishmania’s cell surface carbohydrate antigens. Saccharides heavily envelop the cell surface of Leishmania, lipophosphoglycan (LPG) becoming a significant glycan in most leishmania species. Its intrinsic antigenicity makes this polysaccharide a useful target for developing conjugated vaccine candidates against all leishmaniasis variants. In this report, we present our progress towards the synthesis of the fragments of LPG …

Neuroprognostication In Patients With A Subarachnoid Hemorrhage: A Quasi-Review Of Anti-Inflammatory Agent Administration Versus Blood Pressure Management, Julia Gabalski, Marcie Mcmahon

Soaring: A Journal of Undergraduate Research

A subarachnoid hemorrhage (SAH) is a type of stoke where a blood vessel bursts and causes the subarachnoid space to become filled with blood. Traditional nursing management of SAH includes close monitoring of blood pressure goals in order to prevent complications such as vasospasm. Vasospasm causes delayed cerebral ischemia and neurological deficits secondary to the initial injury. Recent research has expanded understanding of the underlying mechanisms behind the neuroinflammatory cascade that occurs after a SAH. In this study, a methodical search was conducted through the CINAHL and PubMed databases to form a quasi-review of current research. The comparison of traditional …

Evaluating Functional Inhibitors Of Acid Sphingomyelinase As Potential Negative Modulators Of Microvesicle Particle Release In Response To Skin Stressors, Taskin Sabit

Browse all Theses and Dissertations

Many diseases including lupus erythematosus, atopic eczema, and rosacea can be associated with photosensitivity, which is an abnormal response to sunlight. Recent studies by our group have implicated microvesicle particles (MVP) as playing an important role in causing inflammation and systemic immunosuppression. Previous studies show that functional inhibitors of acid sphingomyelinase (FIASMA) can block MVP release in response to ultraviolet B (UVB) radiation or Platelet-activating Factor (PAF) agonist, which are skin stressors. However, more research needs to be conducted to evaluate the role of PAF, UVB and FIASMA in MVP generation and to formulate a therapeutic medication to be potentially …

Influence Of Human And Viral Il-6 On Kshv Infection In Human Tonsil Lymphocytes, Wajd Zakir

Pharmaceutical Sciences (MS) Theses

Infection of B cells by the lymphotropic gamma-herpesvirus Kaposi sarcoma-associated herpesvirus (KSHV) causes Multicentric Castleman Disease, Primary Effusion Lymphoma, and the newly-identified inflammatory syndrome designated KICS. Despite proven connections to lymphoproliferative disorders, little is known about how KSHV invades the human immune system or the early events governing infection in B lymphocytes. IL-6 signaling plays a critical role in KSHV-mediated disease, where elevated hIL-6 levels are positively associated with KSHV viral load and disease progression. This dynamic is even more complex due to the co-existence of human IL-6 (hIL6) and KSHV-encoded viral IL-6 (vIL6) in these diseases. Although the impact …

Nanoscale Characterization Of Interaction Of Nucleosomes With H1 Linker Histone, Ahmed Yesvi Rafa, Shaun Filliaux, Yuri L. Lyubchenko

Journal Articles: Pharmaceutical Sciences

In eukaryotic nuclei, DNA is wrapped around an octamer of core histones to form nucleosomes. H1 binds to the linker DNA of nucleosome to form the chromatosome, the next structural unit of chromatin. Structural features on individual chromatosomes contribute to chromatin structure, but not fully characterized. In addition to canonical nucleosomes composed of two copies each of histones H2A, H2B, H3, and H4 (H3 nucleosomes), centromeres chromatin contain nucleosomes in which H3 is replaced with its analog CENP-A, changing structural properties of CENP-A nucleosomes. Nothing is known about the interaction of H1 with CENP-A nucleosomes. Here we filled this gap …

Neuroimmune Response And Neurodegeneration In Adolescent Rats Following Binge Alcohol Exposure, Catherine Van Doorn

Theses and Dissertations--Pharmacy

Studies of adolescent drinking show a distinct prevalence of binge drinking, including at extreme levels, and this type of drinking has been identified as increasing risk of developing an Alcohol Use Disorder (AUD). Additionally, females suffer greater levels of harm from binge drinking and AUD and in an abbreviated timeline compared to males. Neuroimmune reactivity, specifically with microglial reactivity following binge drinking, may influence the sex differences seen in negative alcohol-related health disparities.

The first set of experiments sought to examine a marker of microglial reactivity, TSPO, in adolescent females and males and found the sexes displayed different temporal and …

Books, Presentations, Posters, Etc.

Abstract: According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), in the US, alcohol use contributes to up to five million emergency department (ED) visits annually. Alcohol withdrawal syndrome (AWS) is a serious and potentially life-threatening condition that can lead to complications such as hallucinations, seizures, and delirium tremens. For many years, the standard treatment for AWS has been symptom-triggered benzodiazepines, often dosed based on symptom scoring tools such as the Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) Score. In recent years, the use of phenobarbital for AWS management has gained popularity, and studies investigating its safety and …

Clinical Outcomes Associated With Mrsa Naat Utilization., Shannon B. Leighton, Pharmd, Emily Fox, Greg Tallman

Books, Presentations, Posters, Etc.

Abstract: A recent analysis by the Oregon Regional Antimicrobial Stewardship Program demonstrated that across the Oregon region, MRSA NAAT from the nares have a high negative predictive value (NPV) of 99.4%. These findings were consistent when stratified by culture site. The high NPV suggests that MRSA NAAT nasal swabs can be useful in promoting de-escalation (e.g., discontinuation) of anti-MRSA treatment. Few studies have evaluated if use of the MRSA NAAT influences anti-MRSA treatment de-escalation, and even fewer have assessed important clinical outcomes related to MRSA NAAT utilization and de-escalation. The goal of this study is to evaluate the frequency of …

Impact Of Pharmacist Concierge Service For Patient With Denied Prior Authorization, Ben Song, Jenifer Smith

Books, Presentations, Posters, Etc.

Abstract: Prior authorization (PA) is an evidence-based utilization management process used by managed care organizations to ensure prescribed products or services are safe, effective, and medically necessary for coverage.2 While PA is important for assessing clinically appropriate medication utilization, however, denials can lead to patient dissatisfaction, administrative burden for providers, and delays in patient care.1,2,3 Recent studies on the effect of PA received mixed results. One study illustrated that in an American Medical Association survey about PA, 91% of physicians reported that patients requiring care experienced care delays, and 75% of patients abandoned their treatments because of obstacles associated with …

Acute Pain Management Of Hospitalized Patients On Medication-Assisted Therapies (Mat) For Opioid Use Disorder (Oud), Ryan Bower, Roland Mikkaeil, Emily H. Hsu, Tracee Mock

Books, Presentations, Posters, Etc.

Abstract: Buprenorphine has been an instrumental tool in Medication Assisted Therapies (MAT) for opioid use disorder (OUD). For hospitalized patients on MAT, the management of acute pain presents a unique challenge to health care providers. A previous study examining buprenorphine discontinuation patterns on medical/surgical floors found that 11.8% of patients had their buprenorphine discontinued due to inadequate analgesia. Furthermore, none of these patients had their buprenorphine restarted prior to discharge. Discontinuation of buprenorphine in hospitalized patients has the potential for wide-reaching implications ranging from risk of withdrawal to relapse secondary to patient loss during the transition from inpatient to outpatient …

The book Dreamland by investigative journalist and storyteller, Sam Quinones encapsulates the complexity of the opioid epidemic through research and interviews with important figures related to the crisis such as physicians, people with opioid use disorder, and pharmaceutical sales representatives, among others. Quinones details that the …

Nanoscale Interaction Of Endonuclease Ape1 With Dna, Sridhar Vemulapalli, Mohtadin Hashemi, Yingling Chen, Suravi Pramanik, Kishor Bhakat, Yuri L. Lyubchenko

Journal Articles: Pharmaceutical Sciences

Apurinic/apyrimidinic endonuclease 1 (APE1) is involved in DNA repair and transcriptional regulation mechanisms. This multifunctional activity of APE1 should be supported by specific structural properties of APE1 that have not yet been elucidated. Herein, we applied atomic force microscopy (AFM) to characterize the interactions of APE1 with DNA containing two well-separated G-rich segments. Complexes of APE1 with DNA containing G-rich segments were visualized, and analysis of the complexes revealed the affinity of APE1 to G-rich DNA sequences, and their yield was as high as 53%. Furthermore, APE1 is capable of binding two DNA segments leading to the formation of loops …

Oberley-Deegan, Yashpal Singh Chhonker, Darryl J. Murry, C. Patrick Reynolds, Barry J. Maurer, Trevor M. Penning, Paul C. Trippier

Journal Articles: Pharmaceutical Sciences

A series of 7-substituted coumarin derivatives have been characterized as pan-aldo-keto reductase family 1C (AKR1C) inhibitors. The AKR1C family of enzymes are overexpressed in numerous cancers where they are involved in drug resistance development. 7-hydroxy coumarin ethyl esters and their corresponding amides have high potency for AKR1C3 and AKR1C2 inhibition. Coumarin amide 3 a possessed IC50 values of 50 nM and 90 nM for AKR1C3 and AKR1C2, respectively, and exhibits 'drug-like' metabolic stability and half-life in human and mouse liver microsomes and plasma. Compound 3 a was employed as a chemical tool to determine pan-AKR1C2/3 inhibition effects both as a …

Discovery Of An Aldo-Keto Reductase 1c3 (Akr1c3) Degrader, Angelica V. Carmona, Shirisha Jonnalagadda, Alfie M. Case, Krishnaiah Maddeboina, Sravan K. Jonnalagadda, Louise F. Dow, Ling Duan, Trevor M. Penning, Paul C. Trippier

Journal Articles: Pharmaceutical Sciences

Aldo-keto reductase 1C3 (AKR1C3) is a protein upregulated in prostate cancer, hematological malignancies, and other cancers where it contributes to proliferation and chemotherapeutic resistance. Androgen receptor splice variant 7 (ARv7) is the most common mutation of the AR receptor that confers resistance to clinical androgen receptor signalling inhibitors in castration-resistant prostate cancer. AKR1C3 interacts with ARv7 promoting stabilization. Herein we report the discovery of the first-in-class AKR1C3 Proteolysis-Targeting Chimera (PROTAC) degrader. This first-generation degrader potently reduced AKR1C3 expression in 22Rv1 prostate cancer cells with a half-maximal degradation concentration (DC₅₀) of 52 nM. Gratifyingly, concomitant degradation of ARv7 was …

Introducing Biosimilar Competition For Cell And Gene Therapy Products, Brian Canter, Sabine Sussman, Stephen Colvill, Nitzan Arad, Elizabeth Staton, Arti Rai

Faculty Scholarship

This article provides an early analysis of the potential for creating future biosimilar competition for cell and gene therapies (CGTs) to lower prices and improve patient access, building on a unique set of interviews with relevant experts. Our discussion addressed regulatory, manufacturing, intellectual property, and market size challenges. Due to CGTs’ complexity, meeting the regulatory requirement of ‘high similarity with no clinically meaningful differences’ will be difficult. Gene therapies are likely better candidates for biosimilar development than cell therapies. Biosimilarity should be met when gene therapy biosimilars contain the same genetic sequence as a reference product, and the variability in …
