Incidental Finding Of Anomalous Pulmonary Venous Return Of The Left Upper Lobe, A Rare Anatomical Variation, Anika Dutta, Loren Zuiderveld Jul 2021

Incidental Finding Of Anomalous Pulmonary Venous Return Of The Left Upper Lobe, A Rare Anatomical Variation, Anika Dutta, Loren Zuiderveld

Journal of Patient-Centered Research and Reviews

Partial anomalous pulmonary venous return (PAPVR) is a rare congenital abnormality in which 1 to 3 of the pulmonary veins connect to the right atrium rather than the left atrium. In this synthesis of the literature on PAPVR of the left upper lobe, we attempt to illustrate this clinical entity using a case detected incidentally on chest computed tomography, explain the anatomical aspects of this anomaly, and summarize the reported incidence and etiology of left-sided PAPVR. Lastly, differential diagnoses, clinical relevance, and management of left-sided PAPVR are presented. The identification of this variant is important, as it may have serious …

Comprehensive Review And Update Of Burning Eye Syndrome, Stephen Giacomazzi, Ivan Urits, Briggs Hoyt, Ashley Hubble, Elyse M. Cornett, Kyle Gress, Karina Charipova, Amnon A. Berger, Hisham Kassem, Alan D. Kaye, Omar Viswanath

Journal of Patient-Centered Research and Reviews

Keratoconjunctivitis sicca (“dry eye”) is a common (14%–30% of adults over age 48) though difficult to treat condition that causes both discomfort and disability with associated dryness, pain, and visual disturbances. Etiology is not clearly understood but is likely varied, with a subset of patients suffering from chronic neuropathic pain referred to as “burning eye syndrome.” This review of existing literature summarizes the clinical presentation, natural history, pathophysiology, and treatment modalities of burning eye syndrome.

Chronicity of burning eye syndrome is likely secondary to increased nociception from the cornea, decrease in inhibitory signals, and nerve growth factor expression alterations. Treatment …

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 …


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 …

Children with intellectual disability (ID) tend to have difficulty with mastering fundamental movement skills, associated with cognitive deficits that impair skill acquisition. In this case study, motor learning evidence was transformed into an object control skills training program for children with ID in a school context. An implementation framework was used for program design, pilot, and evaluation. Research evidence on error-reduced motor learning was combined with practitioners’ insights to inform the program design. Children with ID in the participant school were allocated to a training or control group for the pilot; object control skills proficiency was the measured outcome. The …


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 …

Genetically Encoded Multivalent Liquid Glycan Array Displayed On M13 Bacteriophage, Amira Khalil, Mirat Sojitra, Jasmine Maghera, Emily Rodrigues, Eric J. Carpenter, Shaurya Seth, Daniel Ferrer Vinals, Todd L. Lowary Jul 2021

Genetically Encoded Multivalent Liquid Glycan Array Displayed On M13 Bacteriophage, Amira Khalil, Mirat Sojitra, Jasmine Maghera, Emily Rodrigues, Eric J. Carpenter, Shaurya Seth, Daniel Ferrer Vinals, Todd L. Lowary

Pharmacy

The central dogma of biology does not allow for the study of glycans using DNA sequencing. We report a liquid glycan array (LiGA) platform comprising a library of DNA ‘barcoded’ M13 virions that display 30–1,500 copies of glycans per phage. A LiGA is synthesized by acylation of the phage pVIII protein with a dibenzocyclooctyne, followed by ligation of azido-modified glycans. Pulldown of the LiGA with lectins followed by deep sequencing of the barcodes in the bound phage decodes the optimal structure and density of the recognized glycans. The LiGA is target agnostic and can measure the glycan-binding profile of lectins, …


Development Of Vaccines And Antivirals Against Zika Virus, Aryamav Pattnaik Jul 2021

Development Of Vaccines And Antivirals Against Zika Virus, Aryamav Pattnaik

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The re-emergence of Zika virus (ZIKV), an arbovirus, poses a major global human health concern because of its ability to cause congenital abnormalities and neurological diseases. While many candidate vaccines and antiviral drugs are in the developmental pipeline, none have been approved for use against ZIKV infection. This dissertation describes the characterization of one vaccine and two antiviral drug candidates against ZIKV infection. A bacterial ferritin-based nanoparticle vaccine, termed zDIII-F, is designed to display multiple copies of ZIKV E protein domain III on its surface. These stable nanoparticles are shown to induce robust antibody-mediated protection against lethal ZIKV infection in …

Microfracture For Cartilage Defects In Today’S Orthopaedics: Pearls And Pitfalls, Himanshu Yn, Sufyan Ibrahim

Manipal Journal of Medical Sciences

Microfracture technique has vacillating clinical outcomes, limited demographic applicability, high failure rate, and variable patient satisfaction. Although it does not deserve to be a gold standard technique, there has not been a technique that could overcome all possible disadvantages associated with the technique and at the same time give a favourable result/be suitable for widespread use/not have its own disadvantages. Microfracture, integrated with biomaterial/stem cell transfer has shown promise over the past decade but studies evaluating the long-term efficacy of the tests and standardization are lacking. Besides, cost and operative difficulties limit widespread use. Twenty-five years into the field, microfracture …


Management Of Pararenal Aortic Aneurysms : A Literature Review, Hilman Ibrahim, Akhmadu Muradi, Ihza Fachriza Jun 2021

Management Of Pararenal Aortic Aneurysms : A Literature Review, Hilman Ibrahim, Akhmadu Muradi, Ihza Fachriza

The New Ropanasuri Journal of Surgery

Abdominal aortic aneurysms (AAA) are the most common group of aortic aneurysms. Pararenal aortic aneurysm (PAA) is a classification of AAA where there is no normal aortic segment between the renal artery and the proximal border of the aneurysm. This group has a prevalence of around 20% of all AAA cases. In open repair (open surgery), PAA requires suprarenal clamps or even supraceliac which causes high morbidity. In endovascular procedures, PAA presents difficulties due to the absence of a landing zone to place the graft and the possibility of reintervention after action. A literature review is needed to discuss the …

The Usage Of Resveratrol For Eye Pain After Refractive Surgery, Dennis Nguyen Jun 2021

The Usage Of Resveratrol For Eye Pain After Refractive Surgery, Dennis Nguyen

University Honors Theses

LASEK and PRK are common laser corrective eye procedures that aim to correct the refractive errors of the eye, although these procedures do carry the potential of post-operation complications of dry eye and symptoms of pain and photophobia as a result of corneal innervation damage. Resveratrol was tested on the surface of the cornea to see if the drug would be effective at attenuating post-corrective eye pain. Male and female rats underwent a unilateral corneal abrasion surgery that aimed to mimic the post-op symptoms of PRK. The rats either received the resveratrol drug treatment or a vehicle formulation. The Rat …


Soft Lithographic Replication Of High Length-Scale Micropillars From Laser-Ablated Fused-Silica Templates, Jason Pitts Jun 2021

Soft Lithographic Replication Of High Length-Scale Micropillars From Laser-Ablated Fused-Silica Templates, Jason Pitts

University Honors Theses

Soft lithography is a well-established route to wafer-scale reproduction of micro- and nanoscale features in a wide variety of materials. Nevertheless, micron length scales have yet to be explored, despite the potential utility of such structures. Here, polymer micropillars of 6-12 μm length, approximately 0.5-1.5 μm wide at 10 μm spacing are reproduced from a polydimethylsiloxane (PDMS) mold made from patterned cellulose acetate (CA). The patterned CA was cast from a rigid fused silica template machined by a pulsed femtosecond laser. Pore topographic features were successfully reproduced in Norland Optical Adhesive (NOA), polycaprolactone (PCL), Nafion, acrylonitrile butadiene styrene (ABS), and …

Pharmacy Faculty Articles and Research

Metastasis continues to be the primary cause of all cancer-related deaths despite the recent advancements in cancer treatments. To evaluate the role of mutations in overall survival (OS) and treatment outcomes, we analyzed 957 metastatic patients with seven major cancer types who had available molecular testing results with a FoundationOne CDx® panel. The most prevalent genes with somatic mutations were TP53, KRAS, APC, and LRP1B. In this analysis, these genes had mutation frequencies higher than in publicly available datasets. We identified that the somatic mutations were seven mutually exclusive gene pairs and an additional fifty-two co-occurring gene pairs. Mutations …

The Embodiment Of Discovery: An Adapted Framework For Qualitative Analysis Of Lived Experiences, Helen B. Hernandez, Laurie P. Dringus

The Qualitative Report

We reflect on our process of working with an adapted framework as an effective strategy for analyzing and interpreting the results of our qualitative study on the lived experiences of insulin pump trainers. Interpretative Phenomenological Analysis (IPA) was applied as the overarching research methodology and was encapsulated into a framework adapted from Bonello and Meehan (2019) and from Chong (2019). We describe this framework as the “embodiment of discovery” to posit the researcher’s tangible experience of discovering the meaning of data that also brought transparency to the researcher’s process for data analysis and interpretation. We present challenges the doctoral student …


Detection Methods And Clinical Applications Of Circulating Tumor Cells In Breast Cancer, Hongyi Zhang, Xiaoyan Lin, Yuan Huang, Minghong Wang, Chunmei Cen, Shasha Tang, Marcia R. Dique, Lu Cai, Manuel A. Luis, Jillian Smollar, Yuan Wan, Fengfeng Cai Jun 2021

Detection Methods And Clinical Applications Of Circulating Tumor Cells In Breast Cancer, Hongyi Zhang, Xiaoyan Lin, Yuan Huang, Minghong Wang, Chunmei Cen, Shasha Tang, Marcia R. Dique, Lu Cai, Manuel A. Luis, Jillian Smollar, Yuan Wan, Fengfeng Cai

Publications and Research

Circulating Tumor Cells (CTCs) are cancer cells that split away from the primary tumor and appear in the circulatory system as singular units or clusters, which was first reported by Dr. Thomas Ashworth in 1869. CTCs migrate and implantation occurs at a new site, in a process commonly known as tumor metastasis. In the case of breast cancer, the tumor cells often migrate into locations such as the lungs, brain, and bones, even during the early stages, and this is a notable characteristic of breast cancer. Survival rates have increased significantly over the past few decades because of progress made …


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 …


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. …


Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass Jun 2021

Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support …
