Developing Deep-Learning Methods For Diagnosis And Prognosis Of Pediatric Progressive Diseases Using Modern Imaging Techniques, Mahdieh Shabanian Dec 2021

Developing Deep-Learning Methods For Diagnosis And Prognosis Of Pediatric Progressive Diseases Using Modern Imaging Techniques, Mahdieh Shabanian

Theses and Dissertations (ETD)

Purpose and Rationale. Central nervous system manifestations form a significant burden of disease in young children. There have been efforts to correlate the neurological disease state in tuberous sclerosis complex (TSC) neurological disease state with imaging findings is a standard part of patient care. However, such analysis of neuroimaging is time- and labor-intensive. Automated approaches to these tasks are needed to improve speed, accuracy, and availability. Automated medical image analysis tools based on 3D/2D deep learning algorithms can help improve the quality and consistency of image diagnosis and interpretation for cognitive disorders in infants. We propose to automate neuroimaging analysis …


Examination Of Antiviral Resistance In Venezuelan Equine Encephalitis Virus, Jasper Lee Dec 2021

Examination Of Antiviral Resistance In Venezuelan Equine Encephalitis Virus, Jasper Lee

Theses and Dissertations (ETD)

Venezuelan equine encephalitis virus (VEEV) is a New World Alphavirus that causes Venezuelan equine encephalitis (VEE), which is characterized by a febrile illness that can progress to neurological disease and death. While no major outbreaks of VEE have occurred since 1995, VEEV is a virus of concern as, in addition to its spread through mosquitos, it can be aerosolized and used as a bioweapon. Unfortunately, there are currently no FDA-approved vaccines or antivirals against VEEV. Efforts have been made to discover small molecules with an inhibitory effect on VEEV, but the potential for emergence of antiviral resistance to these compounds …


Identifying The Molecular Cause Of Extreme Endoplasmic Reticulum Dilation In Pediatric Osteosarcoma And Its Relationship To The Disease, Rachael Wood Dec 2021

Identifying The Molecular Cause Of Extreme Endoplasmic Reticulum Dilation In Pediatric Osteosarcoma And Its Relationship To The Disease, Rachael Wood

Theses and Dissertations (ETD)

Pediatric osteosarcoma tumors are characterized by an unusual abundance of grossly dilated endoplasmic reticulum and an immense genomic instability that has complicated identifying new effective molecular therapeutic targets. Here we report a novel molecular signature that encompasses the majority of 108 patient tumor samples, PDXs and osteosarcoma cell lines. These tumors exhibit reduced expression of four critical COPII vesicle proteins that has resulted in the accumulation of procollagen-I protein within ‘hallmark’ dilated ER. Using CRISPR activation technology, increased expression of only SAR1A and SEC24D to physiologically normal levels was sufficient to restore both collagen-I secretion and resolve dilated ER morphology …


Ecology Of Hantaviruses In Rodent Reservoirs And Their Early Innate Immune Responses In Human Model Systems, Evan Peter Williams Dec 2021

Ecology Of Hantaviruses In Rodent Reservoirs And Their Early Innate Immune Responses In Human Model Systems, Evan Peter Williams

Theses and Dissertations (ETD)

The spillover of zoonotic RNA viruses is responsible for a great deal of the disease outbreaks in human populations. These spillover events are set to continue due to anthropogenic and environmental changes that impact the distribution of these viruses. The viruses in the family Hantaviridae are classified as one of these emerging zoonotic RNA viruses. The spillover of the viruses in this family are responsible for two severe human diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). These viruses are distributed across the globe and are responsible for a large number of human disease cases with …

Purpose/Background Central venous catheters (CVC) are typical for critically ill patients in the intensive care unit (ICU). Due to the invasiveness of this procedure, there is a high risk for central line-associated bloodstream infection (CLABSI). These infections have been known to increase mortality and morbidity, medical costs, and reduce hospital reimbursements. Evidenced-based interventions were grouped to assemble a central line bundle to decrease the number of CLABSIs and improve patient outcomes. This scoping review will evaluate the literature and examine the association between reduced CLABSI rates and central line bundle care implementation or current use.

Methods A literature review was …

Doctor of Nursing Practice Projects

Purpose/Background Overdose deaths in the U.S. from opioids have dramatically increased since the COVID-19 pandemic. Although medicated-assisted treatment (MAT) programs are widely available for sufferers of opiate addiction, many drop out of treatment prematurely. Twelve-step programs are considered a valuable part of treatment, but few studies have examined the effect of combining these approaches. We aimed to compare abstinence rates among patients receiving MAT who were referred to 12-step programs to those only receiving MAT.

Methods In this prospective study, a cohort of participants from a MAT clinic agreeing to attend a 12-step program was compared to 15 controls selected …

Evaluation And Feasibility Of A Head Positioning Intervention In Patients With Intraparenchymal Hemorrhage, Wendy L. Dusenbury Nov 2021

Evaluation And Feasibility Of A Head Positioning Intervention In Patients With Intraparenchymal Hemorrhage, Wendy L. Dusenbury

Theses and Dissertations (ETD)

Stroke caused by intraparenchymal hemorrhage (IPH) is most commonly the result of hypertension-induced blood vessel rupture in the brain and is associated with devastating disability and high rates of death. To date, no intervention has improved outcomes in IPH stroke patients; however, head elevation may be one of the most important first steps to promote clinical stability in the hyperacute stage of IPH stroke because of the risk of increased intracranial pressure (ICP) in these patients. Nursing research completed in the late 1970s and early 1980s in patients with increased ICP due to traumatic brain injury showed that elevating the …

Intraoperative Dexmedetomidine For Reduction Of Postoperative Delirium In The Elderly: A Scoping Review, Gregory B. Harris Bsn, Rn, Srna, Brooke N. Hatchell Bsn, Rn, Srna, Davelin D. Woodard Bsn, Rn, Srna, Dwayne Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Background/Purpose: Post-operative delirium leads to significant morbidity in elderly patients, yet there is no regimen to prevent POD. Opioid use in the elderly surgical population is of the most significant risk factors for developing POD. The purpose of this scoping review is to recognize that Dexmedetomidine mitigates cognitive dysfunction secondary to acute pain and the use of narcotic analgesia by decreasing the amount of norepinephrine (an excitatory neurotransmitter) released during times of stress. This mechanism of action also provides analgesia through decreased perception and modulation of pain.

Methods: The authors developed eligibility criteria for inclusion of articles and performed a …

The purpose of this DNP project is to examine what is known from existing literature about postoperative ileus development in the adult surgical patient population after receiving intraoperative opioids versus a combination of intraoperative opioids and NSAIDs.


Pain Control: Opioid Vs. Nonopioid Analgesia During The Immediate Postoperative Period, Shamsie M. Lumpkin Bsn, Srna, Isaac W. Parrish Bsn, Srna, Austin S. Terrell Bsn, Srna, Dwayne S. Accardo Dnp, Aprn, Crna Jul 2021

Pain Control: Opioid Vs. Nonopioid Analgesia During The Immediate Postoperative Period, Shamsie M. Lumpkin Bsn, Srna, Isaac W. Parrish Bsn, Srna, Austin S. Terrell Bsn, Srna, Dwayne S. Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Background Opioid analgesia has become the mainstay for acute pain management in the postoperative setting. However, the use of opioid medications comes with significant risks and side effects. Due to increasing numbers of prescriptions to those with chronic pain, opioid medications have become more expensive while becoming less effective due to the buildup of patient tolerance. The idea of opioid-free analgesic techniques has rarely been breached in many hospitals. Emerging research has shown that opioid-sparing approaches have resulted in lower reported pain scores across the board, as well as significant cost reductions to hospitals and insurance agencies. In addition to …


Dexmedetomidine Vs Fentanyl In Attenuating The Sympathetic Surge During Endotracheal Intubation: A Scoping Review, Alexandra Schwieger, Kaelee Shrewsbury, Paul Shaver, Dwayne Accardo Dnp, Crna Jul 2021

Dexmedetomidine Vs Fentanyl In Attenuating The Sympathetic Surge During Endotracheal Intubation: A Scoping Review, Alexandra Schwieger, Kaelee Shrewsbury, Paul Shaver, Dwayne Accardo Dnp, Crna

Doctor of Nursing Practice Projects

Purpose/Background Direct laryngoscopy and endotracheal intubation after induction of anesthesia can cause a reflex sympathetic surge of catecholamines caused by airway stimulation. This may cause hypertension, tachycardia, and arrhythmias. This reflex can be detrimental in patients with poor cardiac reserve and can be poorly tolerated and lead to adverse events such as myocardial ischemia. Fentanyl, a potent opioid, with a rapid onset and short duration of action is given during induction to block the sympathetic response. With a rise in the opioid crisis and finding ways to change the practice in medicine to use less opioids, dexmedetomidine, an alpha 2 …


Postoperative Nausea And Vomiting Implications In Neostigmine Versus Sugammadex, Corey Lee Johnson, Colton Bradley James, Sarah Grace Traughber, Charles Anthony Walker, Dwayne Accardo Dnp, Aprn, Crna Jul 2021

Postoperative Nausea And Vomiting Implications In Neostigmine Versus Sugammadex, Corey Lee Johnson, Colton Bradley James, Sarah Grace Traughber, Charles Anthony Walker, Dwayne Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Purpose/Background: Postoperative nausea and vomiting (PONV) is a frequent complaint in the postoperative period, which can delay discharge, result in readmission, and increase cost for patients and facilities. Inducing paralysis is common in anesthesia, as is utilizing the drugs neostigmine and sugammadex as reversal agents for non-depolarizing neuromuscular blockers. Many studies are available that compare these two drugs to determine if neostigmine increases the risk of PONV over sugammadex. Sugammadex has a more favorable pharmacologic profile and may improve patient outcomes by reducing PONV.

Methods: This review included screening a total of 39 studies and peer-reviewed articles that looked at …


Opioid Free Anesthesia To Prevent Post Operative Nausea/Vomiting, Aleksander Acred, Milena Devineni, Lindsey Blake, Cindi Dabney Dnp, Crna Jul 2021

Opioid Free Anesthesia To Prevent Post Operative Nausea/Vomiting, Aleksander Acred, Milena Devineni, Lindsey Blake, Cindi Dabney Dnp, Crna

Doctor of Nursing Practice Projects

Purpose The purpose of this study is to compare the incidence of post-operative nausea and vomiting (PONV) in opioid-utilizing and opioid-free general anesthesia. Background PONV is an extremely common, potentially dangerous side effect of general anesthesia. PONV is caused by a collection of anesthetic and surgical interventions. Current practice to prevent PONV is to use 1-2 antiemetics during surgery, identify high risk patients and utilize tracheal intubation over laryngeal airways when indicated. Current research suggests minimizing the use of volatile anesthetics and opioids can reduce the incidence of PONV, but this does not reflect current practice.

Methods In this scoping …


Feasibility And Acceptability Of Using Mobile Health Apps In Underserved Patients With Diabetes, Jieyu Luo Jun 2021

Feasibility And Acceptability Of Using Mobile Health Apps In Underserved Patients With Diabetes, Jieyu Luo

Theses and Dissertations (ETD)

Introduction. Diabetes mellitus is a condition with a growing morbidity and mortality burden. An estimated 30 million adults currently live with diabetes, with each individual spending over $9500 annually on medical care. The successful management of diabetes is a lifelong endeavor. This involves balancing a variety of factors including diet, medications, and glucose monitoring. It has been well established that successful control of diabetes depends largely upon patients’ daily lifestyle habits and activities. Not all patients, however, have the resources necessary for effective diabetes management. Health disparities lead to a higher rate of diabetes development in minority and poor populations. …


Iatrogenic Electrocautery Damage And Cellular-Based Corrosion Of Total Joint Arthroplasty Biomaterials, Kirsten Carol Miller Jun 2021

Iatrogenic Electrocautery Damage And Cellular-Based Corrosion Of Total Joint Arthroplasty Biomaterials, Kirsten Carol Miller

Theses and Dissertations (ETD)

Introduction. The number of patients undergoing a Primary Total Knee Arthroplasty (PTKA) has been increasing steadily each year. Of those PTKA patients, 20% report long-term pain and/or some functional deficit. Cobalt-Chromium-Molybdenum (CoCrMo) alloy is one of the most used materials in Total Joint Arthroplasty (TJA) implants due the material’s high strength, high corrosion resistance, and biocompatibility. The release of metal ions and potential occurrence of metallosis in TJA has been shown to be detrimental to the longevity of the implant. The mechanisms leading to this increase in metal ion concentrations have been up for debate, with some believing it is …


Near-Field Electrospinning And Characterization Of Biodegradable Small Diameter Vascular Grafts, William E. King Iii Jun 2021

Near-Field Electrospinning And Characterization Of Biodegradable Small Diameter Vascular Grafts, William E. King Iii

Theses and Dissertations (ETD)

The ideal “off the shelf” tissue engineering, small-diameter (< 6 mm inner diameter (ID)) vascular graft hinges on designing a template that facilitates transmural ingrowth of capillaries to regenerate an endothelized neointimal surface. Previous traditionally electrospun (TES) approaches to create bioresorbable vascular grafts lack the pore sizes required to facilitate transmural capillary ingrowth required for successful in situ neovascular regeneration. Therefore, the ability to create scaffolds with program-specific architectures independent of fiber diameter via the relatively recent sub-technique of near-field electrospinning (NFES) represents a promising solution to create tissue engineering vascular grafts. These programmed large pore sizes are anticipated to promote in situ regeneration and improve the outcomes as well as the quality of life of patients with arterial disease.

In this dissertation, we manufactured via NFES as well as characterized biodegradable polydioxanone (PDO) small-diameter vascular grafts. Chapter 1 introduces the need for off-the-shelf, small-diameter vascular grafts to facilitate in situ regeneration, the process and pore size limitations of TES vascular grafts, and the promising use of NFES to develop precisely tailored PDO vascular grafts. Chapter 2 describes the process of NFES and details the current progress in NFES of biomedical polymers as well as the major limitations that exist in the field. Chapters 3, 4, and 5 contain primary research …


Effects Of Social Determinants Of Health In Progression To Type 2 Diabetes, Folabi I. Ariganjoye May 2021

Effects Of Social Determinants Of Health In Progression To Type 2 Diabetes, Folabi I. Ariganjoye

Applied Research Projects

The prevalence of prediabetes and diabetes in the United States and around the world has increased faster than expected in the last 30 years. The economic burden this costs a nation can be astronomic both in terms of expense and loss in productivity. One-third of U.S. adults, 86 million people, have prediabetes. Effective management is needed that can reach these 86 million, and others at high risk, to reduce their progression to diagnosed Type 2 diabetes. After the literature review, there was not enough literature to support how these led to the progression to diabetes. The abundant literature is centered …

Efficacy Of Integrating Cbt For Mental Health Care Into Substance Abuse Treatment In Patients With Comorbid Disorders Of Substance Abuse And Mental Illness, Laura U. Madu, Jacqueline Sharp, Bobby Bellflower

Doctor of Nursing Practice Projects

Abstract: Multiple studies have found that psychiatric disorders, like mood disorders and substance use disorders, are highly comorbid among adults with either disorder. Integrated treatment refers to the treatment of two or more conditions and the use of multiple therapies such as the combination of psychotherapy and pharmacotherapy. Integrated therapy for comorbidity per numerous studies has consistently been superior to the treatment of individual disorders separately. The purpose of this QI project was to identify the effectiveness of Cognitive Behavioral Therapy (CBT) instead of current treatment as usual for treating Substance Use Disorder (SUD) or mental health diagnosis independently. It …
