Quality Improvement (Qi) Project Aimed At Reducing Unnecessary Antibiotic Usage Among Older Adult Patients By Addressing Inappropriate Antibiotic Prescribing In Primary And Long-Term Care Settings, Pamela M. Thomas

Seton Hall University Dissertations and Theses (ETDs)

Antibiotic overuse among older adults remains a significant patient safety and public health concern. Recent national data indicate that approximately 30%–50% of outpatient antibiotic prescriptions may be unnecessary, particularly for viral or self-limiting conditions (Chua et al., 2021). Antimicrobial resistance has been associated with more than 1.27 million deaths globally (Murray et al., 2022). This quality improvement project evaluated a multifaceted antimicrobial stewardship intervention in primary and long-term care settings. Baseline review of 167 antibiotic cases revealed 37.1% were inappropriate or questionable, and 28.7% lacked adequate diagnostic documentation. The intervention incorporated provider education, electronic health record decision-support tools, audit and …

Unlocking Hope: Mirtazapine's Promise In Obsessive-Compulsive Disorder Treatment, Rebecca K. Hicks, Iram Kingson, Jordan Gaal, Suzanne Holroyd

Marshall Journal of Medicine

Obsessive-compulsive disorder (OCD) is a chronic and debilitating psychiatric condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions). While selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy (CBT) are first-line treatments for OCD, a significant proportion of patients remain refractory to these interventions. Mirtazapine, an atypical antidepressant with unique pharmacological properties, has emerged as a potential adjunctive therapy for treatment-resistant OCD. This review synthesizes existing evidence regarding the efficacy and safety profile of mirtazapine in OCD management. We analyze clinical trials, observational studies, and case reports, distinguishing high- vs. low-quality evidence, and discuss mechanisms underlying mirtazapine's therapeutic effects. Additionally, …

Inflammatory Co-Regulation Of Voltage-Gated Sodium Channels And Na,K-Atpase In Metastatic Breast Cancer, Steven D. Scahill, Kelly Jean Sherman, Dennis Paul

School of Graduate Studies Faculty Publications

Sodium regulation is a potentially major driver of cancer metastasis. Voltage-gated sodium channels (VGSCs) and Na,K-ATPase are sodium transporters that are upregulated in many advanced carcinomas and are implicated as metastatic drivers. However, little is known about what drives this overexpression, how these proteins influence metastatic behavior, or whether these complementary sodium transporters are co-regulated in cancer. Using sodium transporter regulation in healthy neurons as a model, the present study demonstrated that the inflammatory mediator tumor necrosis factor alpha (TNFα) affects the expression of VGSCs and Na,K-ATPase in an in vitro model of metastatic breast cancer. Acute TNFα challenge increased …

School of Medicine Faculty Publications

Introduction: There are no treatments directly targeting the pulmonary vasculature in chronic obstructive pulmonary disease (COPD), and further characterization of the underlying endothelial cell (EC) abnormalities could be helpful in drug development. Methods: We investigated the influence of exercise and the prostacyclin analog iloprost on extracellular vesicles derived from ECs (eEVs) in 15 moderate–severe COPD patients who were enrolled in a randomized, placebo-controlled crossover trial of iloprost. Results: Active smokers had a profile consistent with inflammatory-derived EVs, while exacerbation-prone COPD subjects had a profile consistent with apoptosis-derived eEVs. There were no significant effects of iloprost on eEV levels. However, there …

Emerging Clinical Role Of Tavapadon, A Novel Dopamine Partial Agonist, In The Treatment Of Parkinson’S Disease, Alan D. Kaye, Bennett M. Ford, Brennan M. Abbott, Kalob M. Broocks, Sofia Novacic, Sahar Shekoohi

School of Medicine Faculty Publications

Tavapadon, a novel oral dopamine-D1R/D5R partial agonist, has been studied in recent years for the treatment of late-stage development Parkinson’s disease (PD). Levodopa, a dopamine precursor that currently remains the gold-standard first-line therapy for PD motor symptoms, serves as a benchmark against emerging dopaminergic agents. By selectively activating D1-family receptors on direct-pathway medium neurons, Tavapadon differs in that it delivers levodopa-level motor benefit while avoiding its many D2R/D3R-mediated adverse effects. In placebo-controlled trials, Tavapadon produced clear, clinically meaningful gains in motor function and day-to-day activities, as captured by the Unified Parkinson’s Disease Rating Scale (UPDRS). Recent late-stage results have revealed …

Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

The novel (nua) kinases 1 and 2 are two of 12 AMP-activated protein–related kinases whose signaling pathways are involved in cancer progression, as well as neurologic, fibrotic, and inflammatory diseases. Currently, there are 80 Food and Drug Administration-approved kinase inhibitors which target roughly 24 of the 500+ known human kinases, leaving most kinases underexplored, including NUAK1 and NUAK2. Thus, there is a critical need for selective inhibition of NUAK1 and NUAK2 signaling. Here, we review the protein structure, known upstream regulators and downstream targets, and expression profiles of NUAK1 and NUAK2 in cancerous compared to noncancerous tissue. We also delineate …

Immunotherapy, particularly that based on blocking checkpoint proteins in many tumors, including melanoma, Merkel cell carcinoma, non-small cell lung cancer (NSCLC), triple-negative breast (TNB cancer), renal cancer, and gastrointestinal and endometrial neoplasms, is a therapeutic alternative to chemotherapy. Immune checkpoint inhibitor (ICI)-based therapies have the potential to target different pathways leading to the destruction of cancer cells. Although ICIs are an effective treatment strategy for patients with highly immune-infiltrated cancers, the development of different adverse effects including cutaneous adverse effects during and after the treatment with ICIs is common. ICI-associated cutaneous adverse effects include mostly inflammatory and bullous dermatoses, as …

Exercise intolerance, a hallmark of heart failure with preserved ejection fraction (HFpEF) exacerbated by obesity, involves unclear mechanisms related to skeletal muscle metabolism. In a “2-hit” model of HFpEF, we investigated the ability of exercise therapy (voluntary wheel running) to reverse skeletal muscle dysfunction and exercise intolerance. Using state-of-the-art metabolic cages and a multiomic approach, we demonstrate exercise can rescue dysfunctional skeletal muscle lipid and branched-chain amino acid oxidation and restore exercise capacity in mice with cardiometabolic HFpEF. These results underscore the importance of skeletal muscle metabolism to improve exercise intolerance in HFpEF.

School of Graduate Studies Faculty Publications

The endoplasmic reticulum is organized into ordered regions enriched in cholesterol and sphingomyelin, and disordered microdomains characterized by more fluidity. Rabbit CYP1A1 and CYP1A2 localize into disordered and ordered microdomains, respectively. Previously, a CYP1A2 chimera containing the first 109 amino acids of CYP1A1 showed altered microdomain localization. The goal of this study was to identify specific residues responsible for CYP1A microdomain localization. Thus, CYP1A2 chimeras containing substitutions from homologous regions of CYP1A1 were expressed in HEK 293T/17 cells, and the localization was examined after solubilization with Brij 98. A CYP1A2 mutant with the three amino acids from CYP1A1 (VAG) at …

Protein tyrosine kinases (PTKs) function as key molecules in the signaling pathways in addition to their impact as a therapeutic target for the treatment of many human diseases, including cancer. PTKs are characterized by their ability to phosphorylate serine, threonine, or tyrosine residues and can thereby rapidly and reversibly alter the function of their protein substrates in the form of significant changes in protein confirmation and affinity for their interaction with protein partners to drive cellular functions under normal and pathological conditions. PTKs are classified into two groups: one of which represents tyrosine kinases, while the other one includes the …

Differential Effect Of An Evolving Amyloid And Tau Pathology On Brain Phospholipids And Bioactive Lipid Mediators In Rat Models Of Alzheimer-Like Pathology, Sonia Do Carmo, Marie Audrey I.

School of Graduate Studies Faculty Publications

Background: Brain inflammation contributes significantly to the pathophysiology of Alzheimer’s disease, and it is manifested by glial cell activation, increased production of cytokines/chemokines, and a shift in lipid mediators from a pro-homeostatic to a pro-inflammatory profile. However, whether the production of bioactive lipid mediators is affected at earlier stages, prior to the deposition of Aβ plaques and tau hyperphosphorylation, is unknown. The differential contribution of an evolving amyloid and tau pathology on the composition and abundance of membrane phospholipids and bioactive lipid mediators also remains unresolved. Methods: In this study, we examined the cortical levels of DHA- and AA-derived bioactive …

If1 Promotes Cellular Proliferation And Inhibits Oxidative Phosphorylation In Mouse Embryonic Fibroblasts Under Normoxia And Hypoxia, Lothar Lauterboeck, Sung Wook Kang, Donnell White, Rong Bao, Parnia Mobasheran, Qinglin Yang

School of Graduate Studies Faculty Publications

ATP synthase inhibitory factor subunit 1 (IF1) is an inhibitory subunit of mitochondrial ATP synthase, playing a crucial role in regulating mitochondrial respiration and energetics. It is well-established that IF1 interacts with the F1 sector of ATP synthase to inhibit the reversal rotation and, thus, ATP hydrolysis. Recent evidence supports that IF1 also inhibits forward rotation or the ATP synthesis activity. Adding to the complexity, IF1 may also facilitate mitophagy and cristae formation. The implications of these complex actions of IF1 for cellular function remain obscure. In the present study, we found that IF1 expression was markedly upregulated in hypoxic …

Melanoma frequently harbors genetic alterations in key molecules leading to the aberrant activation of PI3K and its downstream pathways. Although the role of PI3K/AKT/mTOR in melanoma progression and drug resistance is well documented, targeting the PI3K/AKT/mTOR pathway showed less efficiency in clinical trials than might have been expected, since the suppression of the PI3K/mTOR signaling pathway-induced feedback loops is mostly associated with the activation of compensatory pathways such as MAPK/MEK/ERK. Consequently, the development of intrinsic and acquired resistance can occur. As a solid tumor, melanoma is notorious for its heterogeneity. This can be expressed in the form of genetically divergent …

Melanoma is the third most common type of skin cancer, characterized by its heterogeneity and propensity to metastasize to distant organs. Melanoma is a heterogeneous tumor, composed of genetically divergent subpopulations, including a small fraction of melanoma-initiating cancer stem-like cells (CSCs) and many non-cancer stem cells (non-CSCs). CSCs are characterized by their unique surface proteins associated with aberrant signaling pathways with a causal or consequential relationship with tumor progression, drug resistance, and recurrence. Melanomas also harbor significant alterations in functional genes (BRAF, CDKN2A, NRAS, TP53, and NF1). Of these, the most common are the BRAF and NRAS oncogenes, with 50% …

Chewed Versus Swallowed Ticagrelor In P2y12 Inhibitor-Naïve Patients Undergoing Percutaneous Coronary Intervention, Thomas F. Wilson, Muddasir Ashraf, M. Fuad Jan, Tonga Nfor, Louie Kostopoulos, Joaquin Solis, Jayant Khitha, Ahmad Khraisat, Anthony C. Defranco, Tanvir Bajwa, Suhail Q. Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose: Dual antiplatelet therapy is standard for patients undergoing percutaneous coronary intervention (PCI) with stents. Traditionally, patients swallow the loading dose of a P2Y12 inhibitor before or during PCI. Time to achieve adequate platelet inhibition after swallowing the loading dose varies significantly. Chewed tablets may allow more rapid inhibition of platelet aggregation. However, data for this strategy in patients with stable ischemic heart disease or non-ST-elevation acute coronary syndrome (NSTE-ACS) are less robust.

Methods: In this single-center prospective trial, 112 P2Y12-naïve patients with stable ischemic heart disease or NSTE-ACS on aspirin therapy and who received ticagrelor after coronary angiography but …

Accuracy Of Therapeutic Drug Monitoring In Vancomycin And The Pharmacist Role: A Retrospective Case-Series, Kateryna Parkhomenko

Senior Theses

Vancomycin is a mainstay of therapy for treating virulent and resistant infections, especially methicillin-resistant Staphylococcus aureus (MRSA). However, vancomycin requires therapeutic drug monitoring (TDM) for optimal dosing and treatment. This requires pharmacists to calculate a dosing regimen that correlates to appropriate goal vancomycin concentrations in the blood. Dosing vancomycin can be difficult, as it varies on a patient’s weight, renal function, age, etc. Doses may have to be adjusted in response to out-of-range concentrations, which requires further pharmacy calculations. Inaccurate dosing poses a risk to patient safety and places a resource and time burden on pharmacists. If vancomycin dosing methods …

Modulation Of Cerebral Artery Smooth Muscle Bk Channel Function By Neurosteroids, Kelsey Caroline Cleland North

Theses and Dissertations (ETD)

Voltage-gated and Ca2+ activated K+ channels of large conductance (BK) channels are essential for many key physiological processes, such as controlling the contraction of smooth muscle, including cerebrovascular smooth muscle. Importantly, BK channels are made up of a homotetramer of α subunits which associate with accessory β subunits. These β subunits alter the activity of the channel; this modulation is subunit-specific. Moreover, these accessory subunits have tissue-specific expression, such that the β1 subunit is highly expressed within cerebrovascular smooth muscle and greatly increases the open probability of BK channels. Increased BK channel open probability is linked to increased dilation of …
