Development Of A Clinical Practice Guideline For Diabetic Ketoacidosis (Dka) Management In The Intensive Care Unit, Kushom Gurung Leftwich

Walden Dissertations and Doctoral Studies

This Doctor of Nursing Practice (DNP) project addressed a critical gap in care at a 24-bed, combined, intensive care unit (ICU): The absence of a standardized, evidence-based clinical practice guideline (CPG) for managing diabetic ketoacidosis (DKA). DKA is a life-threatening emergency requiring timely, coordinated, and evidence-driven management. Despite its prevalence, the project site ICU lacked formal guidelines, resulting in fragmented care delivery and inconsistent treatment practices. Project site leadership expressed concerns that the absence of a unified protocol contributed to increased workload for nurses and physicians with frequent interruptions for order verification and delays that compromised patient safety and care …

Staff Education To Increase Nurses’ Knowledge And Comprehension Of Psychiatric Advance Directives, Lenora Johnson

Walden Dissertations and Doctoral Studies

Psychiatric advance directives (PADs) are binding documents through which a patient who has severe mental illness can specify their treatment preferences before becoming mentally ill in a crisis. PADs support patient autonomy, shared decision-making, and reduce the reliance on coercive or involuntary treatments. However, patient record reviews in this practice setting revealed that PAD documentation was not frequently practiced, and nurses were not even aware of or confident enough to assist patients in preparing these directives. This DNP project was designed to bridge this gap by implementing a formal staff education program that would improve the knowledge and awareness of …

In-Silico Assessment Of Aortic Valve Function And Mechanics Under Hypertension, Jason A. Shar, Philippe Sucosky

Faculty Articles

Introduction: Calcific aortic valve disease (CAVD) is the most common heart valve disorder. While hypertension is a major risk factor, the mechanisms by which elevated blood pressure contributes to calcification are largely unknown. Given the established sensitivity of aortic valve (AV) tissue to mechanical cues, hypertension may subject AV leaflets to a stress state conducive to CAVD. To address this hypothesis, the objective of this study was to compare AV function and mechanics under normotensive (NTN, 120/ 80 mmHg), pre-hypertensive (preHTN, 125/80 mmHg) and hypertensive (HTN, 130/90 mmHg) conditions using fluid-structure interaction modeling.

Methods: AV flow and leaflet dynamics were …

Vitamin D Is Glucoprotective In Aging Males But Not Females, Olivia Z B Ginnard, Maria Morales, Ji Youn Youn, Yong Xu, Stephanie R Sisley

Faculty, Staff and Students Publications

Vitamin D supplementation is linked to many beneficial health outcomes in the geriatric population, such as decreased mortality, epigenetic aging, and fracture risk. Conversely, type 2 diabetes is strongly linked to vitamin D deficiency in older adults. However, there is a discrepancy between clinical trials in adults on the efficacy of vitamin D treatment in prediabetes and diabetes. In addition, human data indicates there may be sexual dimorphism in the effect of vitamin D deficiency on dysglycemia that is more pronounced in men. These incongruities may be due to our limited understanding of the underlying mechanisms of vitamin D in …

Unveiling The Link Between Leadership Brand Authenticity, Role Clarity And Customer Responsiveness In Islamic Banking: A Two-Source Analysis, Muhammad Adnan Waseem, Waqas Muhammad, Irfan Irfan, Nauman Wajid

Plymouth Business School

Purpose – This study aims to address the limited understanding of how leadership brand authenticity (LBA) translates into employee and customer outcomes in Islamic banking, a sector where ethical alignment and trust are critical but underexplored in existing literature. Specifically, it explores how LBA influences role clarity and customer responsiveness. It further examines whether role clarity serves as a key mechanism linking authentic leadership to customer-focused outcomes, and whether the bank’s country of origin (COO) shapes this relationship. By addressing both internal organizational alignment and external perceptions, this study offers a comprehensive view of value-driven leadership in Shariah-compliant financial institutions. …

The Inner Workings Of The Flipped Classroom, Kimberly Y. Resendiz

Honors Theses

This paper will be exploring what a flipped classroom is; specifically how teachers use the flipped classroom. First, it is important to note that the flipped classroom is a relatively new method that has popped up as early as the early 2000s. In general, this method allows for teachers to switch the environments in which learning the concepts and doing an activity are switched. The purpose of this paper is to explore the implementation of the four pillars of the flipped classroom, as well as the benefits and challenges STEM teachers face when using flipped classrooms. I have collected data …

Vibrato In The Singing Voice: A Survey Of Vibrato Practices In The Studio For Teachers And Coaches, Anna Alyce Tarver

Electronic Theses and Dissertations Archive

Historically variable in its terminology, “vibrato” was not used until the nineteenth century. Coaches and teachers recognize it as a signature of healthy, expressive singing, except in some stylistically appropriate contexts. However, it continues to raise questions. Little data has been reported on vibrato outside of general characteristics. Only a few sources exist examining the knowledge and skillset of teachers of singing. This survey aimed to gain information on what instructors and coaches are told about vibrato in comparison to what they experience in the voice studio. An anonymous mixed-method survey was distributed to 201 professional voice teachers and coaches; …

A Scalable Cybersecurity Model For Academic Makerspaces, William Faircloth

Cybersecurity Undergraduate Research Showcase

Academic makerspaces have become integral hubs of innovation on university campuses, providing students with access to industrial-grade operational technology (OT) such as 3D printers and CNC machines. However, the security posture for these spaces has overwhelmingly focused on physical safety, creating a significant cybersecurity gap. This oversight leaves networked OT vulnerable to cyberattacks, which threaten student intellectual property, expensive equipment, and the integrity of the broader institutional network. This research addresses this critical vulnerability by developing and implementing a secure and scalable cybersecurity model at the Old Dominion University Computer Science Makerspace, founded on two core principles: robust network segmentation …

For this Doctor of Nursing Practice project in physical medicine and rehabilitation (PM&R), the focus was on enhancing education for acute care nurses about the benefits of inpatient rehabilitation for appropriate patients. The practice problem was the underutilization of inpatient rehabilitation despite its proven benefits in improving patient outcomes and reducing readmissions. With this project, I aimed to educate nurses on identifying suitable candidates for inpatient rehabilitation, thereby improving patient care transitions and outcomes. The practice-focused question revolved around assessing the effectiveness of educational interventions in increasing nurse knowledge and referral rates to inpatient rehab. Analytical strategies included pre- and …

Management Of Stenotrophomonas Mediastinitis After Heart Transplantation For Persistent Driveline Infection: A Case Report, James Lee West, Charles W. Hoopes, Jeremey Walker, Anoma Nellore, Erik J. Orozco-Hernandez

Department of Surgery Faculty Papers

We report a 62-year-old male who had a Heartware left ventricular assist device (LVAD) implantation and subsequently developed a persistent driveline infection, culminating in an abscess along the driveline site despite 18 months of antibiotic treatment. His situation was further complicated post-transplant by the onset of mediastinitis, linked to a previously undervalued Stenotrophomonas maltophilia infection. This report highlights the potential risks of heart transplantation in patients with unresolved LVAD driveline infections, particularly mediastinitis. The presence of existing driveline infections, combined with the immunosuppressed status of patients, necessitates aggressive surgical measures. Our treatment approach, involving multiple mediastinal washouts, omental flap use, …

The Efficacy Of Topical Paromomycin-Gentamicin Versus Topical Paromomycin Alone In The Treatment Of Cutaneous Leishmaniasis: A Meta-Analysis Of Randomized Controlled Trials, Tareq Alshaikh, Mohammed Jihad, Awwad Jomaa

Sultan Qaboos University Medical Journal

Cutaneous leishmaniasis (CL) is the most common protozoal skin infection worldwide. Multiple treatments for CL have been developed to address issues related to resistance, availability, and safety. Topical treatments have shown promise by reducing unnecessary systemic exposure and providing a viable local therapeutic option. A systematic review and meta-analysis were conducted of all literature published before 28 February 2025 through PubMed/MEDLINE, the Cochrane Library, and EBSCO, comparing topical paromomycin–gentamicin (PG) with topical paromomycin alone (PR). Two studies involving a total of 774 patients were included. Relative risks (RRs) from both studies were pooled using a fixed-effect meta-analysis. The meta-analysis showed …

Synthesis And Characterization Of Highly Stable Fisetin Encapsulated In Lecithin-Chitosan-Savie Nanoparticles, Hart Monyatovsky, Travis Anderson, Jay Nadeau

Physics Faculty Publications and Presentations

Senolytic drugs, of the class of polyphenolic flavonoids, have attracted attention for a wide variety of medical applications for which they may be delivered topically, orally, and/or intravenously. However, due to their hydrophobicity and sensitivity to light and oxygen, they have been proven difficult to package and deliver. Here we report a synthesis method for encapsulated fisetin using lecithin-chitosan ionic gelation with a recently reported surfactant that is an alternative to polyethylene glycol (PEG)-containing compounds. Called “Savie” for a contraction of its components, sarcosine-Vitamin E, this surfactant allows for production of sub-100 nm nanoparticles that are bench stable for at …

Spatially Mapped Statewide Estimated Potential Evapotranspiration Using An Efficient Surface Interpolation Method: A Case Study Of South Carolina, Sudhanshu S. Panda, Devendra M. Amatya, Ka Kit Liu, Augustine Muwamba, Timothy J. Callahan

Journal of South Carolina Water Resources

Potential evapotranspiration (PET) exhibits substantial spatial and temporal variability across large landscapes, necessitating site-specific estimation for accurate environmental and water resource assessments. However, obtaining PET or ET data for specific locations across an entire state remains challenging due to the limited number of weather stations and associated environmental datasets. This study aimed to develop an automated geospatial modeling framework to map PET distribution across South Carolina, USA, using PET estimated by the temperature-based Hargreaves–Samani (H–S) method with daily weather data from 59 NOAA stations. Because the accuracy of spatial interpolation depends on both the target variable and the desired spatial …

Assessing Aerobic And Anaerobic Thresholds With Emphasis On Isocapnic Buffering In Endurance Runners, Yahya Mushaflar Fathi, Seyed Houtan Shahidi Dr., Prof. Dr. Mohamed Twfeq Othman Alhusaen Aga

International Journal of Exercise Science

International Journal of Exercise Science 18(5): 1381-1392, 2025. https://doi.org/10.70252/IYED1370 Accurate determination of metabolic thresholds is essential for designing effective endurance training. This study aimed to apply a multi-visit Step–Ramp–Step (SRS) protocol to identify aerobic (VT1) and anaerobic (VT2/RCP) thresholds in trained endurance runners, with a particular focus on delineating the isocapnic buffering region—the ventilatory phase between VT1 and VT2 where carbon dioxide (PetCO₂) remains stable despite rising ventilation. Twelve trained male runners (mean age: 27.1 ± 1.9 years; VO₂max: 60.5 ± 2.1 ml·kg⁻¹·min⁻¹) completed the SRS protocol across separate lab visits. Each session included a 4-minute moderate-intensity phase, a progressive …
