A Comparative Analysis Of Human Insulin Versus Analog Insulin: Glycemic Control, Adherence, Utilization, And Cost-Effectiveness, Sohul Ahmed Shuvo

Theses and Dissertations (ETD)

Background: Despite being a lifesaving medicine for many patients with diabetes, insulin cost is growing out of reach for many. Of the two broad classes of insulin available in the US, analog insulin is newer, costlier, and more widely used than human insulin. The new mode of delivery with pen devices has shown promise in improving adherence and achieving glycemic control and gaining popularity. But comparing adherence to different insulins is challenging due to the lack of a validated insulin adherence method. Very little is known about the comparative benefits of different insulin types and different modes of delivery in …

Inhibition Of Kdm4 With Qc6352 To Target High-Risk Neuroblastoma, Ahmed M. Abuzaid

Theses and Dissertations (ETD)

Neuroblastoma (NB) is a malignancy of improperly maturated nerve tissues of the sympathetic nervous system. It is the most diagnosed extracranial solid tumor of childhood, and it accounts for roughly up to 10% of all childhood malignancies and 15% of all childhood malignancy-related deaths. MYCN amplification, occurring in 20-25% of all NB patients and 50% of all high-risk NB patients, is the well-characterized genetic abnormality and is associated with ill-fated outcomes. Regrettably, in spite of the contemporary therapeutic advances and aggressive combinatorial treatments, the overall 5-year event-free survival rate is roughly 51% with a 5-year overall survival rate of nearly …

The Relationships Among Proprioception, Balance, And Cognitive Perception Of Body Awareness In College Students, Courtney Helmick

Honors College Theses

Introduction: Proprioception is an important physiological function that is essential for activities of daily living as well as exercise and sport performance. Integration of proprioceptive signals plays a key role in both static and dynamic balance. Previously, researchers have assessed the relationship between balance and proprioception, however, the effect of cognitive perception of body awareness has not previously been included in this research. The aim of this pilot study was to explore the relationships among lower extremity proprioception, dynamic balance, and cognitive perception of body awareness in college students.

Methods: Nineteen apparently healthy college students (age 21.26 ± 1.10 years, …

Laboratory Evaluation Of An Enzyme Immunoassay To Detect Coccidioides Galactomannan Antigens In Serum Samples, Anneliese Ahrens

Biological Sciences Undergraduate Honors Theses

Introduction: Coccidioidomycosis (cocci) is an infection caused by fungal pathogens in soil of dry and arid regions in the Southwestern states of the United States. The disease can present itself anywhere in the body, but usually is found in the lungs. The symptoms are very similar to the symptoms of a bacterial or viral respiratory infection, which is one of the reasons it is commonly misdiagnosed or left untreated. The CDC reports cases to have increased 143% from 2014 to 2019, with a mortality rate of 200 deaths per year, however this is likely underreported because of the inadequacies of …

Studies Of Forward Projection Algorithms And Implementation On Pc And Fpga, Minsung Cho

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis first aims to understand how a part of the computed tomography (CT) algorithm called “forward projector” (FP) works and how it can be accelerated at a hardware level. Two methods of FP are defined and studied: pixel-driven and ray-driven. Both methods fundamentally use the property of line integral and Bresenham’s algorithm. As the result of the study of the two FP methods, the ray-driven algorithm implemented in C++ performed 35% faster than the pixe-driven algorithm implemented in Python.This thesis implements the ray-driven forward projector algorithm using field-programmable gate array (FPGA), making use of hardware-acceleration techniques. The result shows …

Oncolytic Virus Immunotherapy: Development And Potential For Cancer Treatment, Olivia Guinness

Honors Scholar Theses

The American Cancer Society estimates that in 2023, 1,958,310 new cancer cases and 609,820 cancer deaths will occur in the United States [16]. A promising therapeutic option that has been supported by recent clinical trials is the use of oncolytic viruses to treat malignant tumors. The mechanism of action of existing treatments, such as chemotherapy, radiotherapy, and surgery, differs from that of oncolytic virus therapy because oncolytic viruses are able to affect cancer cells with specificity, minimizing side effects. When infecting a normal, non-cancerous cell, oncolytic viruses do not replicate, leaving healthy cells unaffected. In tumor cells, oncolytic viruses will …

Gene Expression–Based Algorithms For The Identification Of Drug Combinations In Personalized Medicine, Lon Fong

Dissertations and Theses (Open Access)

Three of the major problems facing cancer therapeutics are 1) drug resistance, the intrinsic or acquired ability of cancer cells to evade the effect of the therapies used to treat them; 2) heterogeneity among individual patients’ disease at the molecular level and the resulting variability in therapeutic response; and 3) the limitations of genomics biomarkers in matching patients to the most effective therapy. One possible solution to drug resistance is the use of combination therapies rather than monotherapies. Use of multiple drugs, each with a different mechanism of action, lowers the chances that the cancer cells will develop or have …

The Diagnostic Odyssey Of Hypermobile Eds Patients: Diagnosis, Clinical Expectations, And Psychosocial Concerns, Madeline Alpar

Dissertations and Theses (Open Access)

Background: Ehlers-Danlos syndrome (EDS) is a highly variable, heritable connective tissue disorder. Hypermobile EDS (hEDS) is the most common subtype of EDS and has no identifiable underlying genetic etiology. Patients with clinical features of hEDS face a long diagnostic odyssey due to lack of genetic testing and wide clinical heterogeneity. Additionally, recent research has shown that genetic institutions limit evaluations for suspected hEDS, adding another barrier to care.

Methods: We developed an online patient survey to explore the diagnostic odyssey of hEDS for those who were diagnosed with or suspicious for hEDS. This survey included sections on demographics, diagnostic information …

Impact Of Personal, Familial, And Socioeconomic Factors On The Return Of Remotely Collected Samples For Genetic Testing, Jordan Zeiger

Dissertations and Theses (Open Access)

There are a multitude of barriers known to impact access to medical care in the United States. COVID-19 has changed and compounded these barriers and led to a shift in the setting of the genetic counseling (GC) appointment, and in sample types used for genetic testing, specifically with use of telemedicine and remotely collected saliva kits. Previous studies have described lack of patient follow-through in returning these kits. Though the understanding of barriers to medical care, including access to genetics services, is well described, there is little in the literature for how these barriers impact the return of remotely collected …

Risk Assessment Framework For Evaluation Of Cybersecurity Threats And Vulnerabilities In Medical Devices, Maureen S. Van Devender

Graduate Theses and Dissertations (2019 - present)

Medical devices are vulnerable to cybersecurity exploitation and, while they can provide improvements to clinical care, they can put healthcare organizations and their patients at risk of adverse impacts. Evidence has shown that the proliferation of devices on medical networks present cybersecurity challenges for healthcare organizations due to their lack of built-in cybersecurity controls and the inability for organizations to implement security controls on them. The negative impacts of cybersecurity exploitation in healthcare can include the loss of patient confidentiality, risk to patient safety, negative financial consequences for the organization, and loss of business reputation. Assessing the risk of vulnerabilities …

Comparison Of Covid-19 Diagnostic Testing Methodologies In The U.S., Joseph Blommel

All Dissertations

The onset of the COVID-19 pandemic brought about a world in which diagnostic testing for the virus that is responsible for COVID-19, SARS-CoV-2, became commonplace. Diagnostic testing was required for myriad reasons beyond simple diagnosis. We set out to compare SARS-CoV-2 testing methods, see if differences sensitivity correlated to increased positivity, and to evaluate self-collection methods.

In examining the Limit of Detection (LoD) of tests receiving FDA Emergency Use Authorization (EUA), our findings indicated that there were considerable differences in LoD. However, these differences in observed sensitivity were not correlated with the methodologic differences as reported in EUA documentation.

We …

A Proof Of Concept For Detection Of Palato-Lingual Contact Without Intraoral Electrodes In A Human Participant, Amitava Biswas

Master's Theses

The author of this thesis conceived and investigated an unexpected electrical signal that may not be noticed during regular electroglottography (EGG) when electrodes are conventionally placed on the anterior surface of the throat. It appears that there is a measurable electrical signal from the EGG equipment when electrodes are placed over the frontal cheek (belly of zygomatic muscle), and the tongue is elevated to contact the hard palate, or the tongue is lowered to break the contact. Therefore, this phenomenon is designated as unconventional electroglottography (UEGG, Dr. Steven Cloud, private communication, July 17, 2022).

Two distinctive patterns of waveforms were …

Pkpd-Model Based Preclinical Characterization Of The Activity Of Spectinamide 1599 Against Mycobacterial Subpopulations. And The Identification Of Potential Partners For Combination Therapy, Zaid Hanif Temrikar

Theses and Dissertations (ETD)

Tuberculosis is one of the top 10 causes of death worldwide and the leading cause of death from a single infectious agent prior to COVID19. Mycobacterium tuberculosis (Mtb) is the causative agent of TB. The interaction between Mtb and the immune system leads to development of diverse environmental niches and physiology within the lung of the TB patients. Mtb is thought to adapt and thrive in such an environment by transforming to different phenotypic variants. Such variants are difficult to kill and are thought to prolong TB pharmacotherapy. Spectinamide 1599 is a synthetic modification of spectinomycin that has demonstrated excellent …

Doctor of Nursing Practice Projects

Purpose/Background

Endotracheal intubation and laryngoscopy potentiate the cardiovascular response in the form of hypertension, tachycardia, and ventricular arrhythmias. Suppression of this adrenergic response is necessary to ensure patient safety. Currently, anesthesia providers employ many methods to attenuate the sympathetic response without established guidelines. As such, our project aimed to determine the effectiveness of fentanyl compared to esmolol in attenuating the hemodynamic response during laryngoscopy and endotracheal intubation within the first five minutes and throughout the intraoperative period.

Methods

A literature review was completed of ten critically appraised articles from the years 2011-2022. Articles in the review included randomized control studies, …
