Scalp, Oral, And Nail Pemphigus Vulgaris: Clinical Characteristics And A Review Of The Literature., Emily Eachus, Lauren E Delamielleure, Samrah Mitha, Taha F Rasul, Arfa Faiz
HPD Articles
Pemphigus vulgaris (PV) is a rare disease that affects the skin and mucous membranes, causing blistering and erosions. Identifying and effectively managing atypical presentations of pemphigus vulgaris can be challenging due to its rarity. We describe a 32-year-old male patient with a medical history including prediabetes, moderate asthma, hyperlipidemia, coccidioidomycosis, and respiratory infections. He was evaluated via telehealth in the allergy and immunology clinic for uncontrolled asthma. Initially, he complained of a whitish film in the mouth while on treatment with fluticasone and salmeterol. He also noted new vesicular lesions on his scalp and body. When evaluated later in the …

Meeting, Moving, Mastering - A Text Analysis Of The Aesthetic Attractions Of 'Wild Swimming', Dagmar Dahl, Åsa I. Bäckström
International Journal of Aquatic Research and Education
Why are people fascinated by swimming in nature? This article addresses the aesthetic experiences of wild swimming as expressed by five wild swimming authors in their books. Drawing from aesthetic philosophy, we analyze the ways in which the appeal of wild swimming is described on three levels: the allure of water in the environment, the sensory encounter between water and the body, and the experience of moving in water. Furthermore, with reference to Seel’s concept of nature aesthetics (1996), the experience of wild swimming is analyzed in terms of contemplation, correspondence, and imagination. We can conclude that the special intensity …

Communication Assessment Tools For Emergency Department Nurses Who Interact With Individuals With Intellectual And Developmental Disabilities, Holly Hunt
Doctor of Nursing Practice Scholarly Projects
Abstract/Executive Summary
Problem Statement: Communication is an essential part of every nurse-patient interaction. During the best of times the patient and nurse can clearly understand each other and engage in successful interaction with positive patient outcomes. Individuals with intellectual and developmental disabilities (IDD) often use nontraditional ways of communicating that can complicate the ideal nurse-patient interaction. When a patient presents with a different method of communicating, the nurse must possess tools available to facilitate a successful interaction. Identifying such a tool or if one cannot be found building a sample tool is vital for positive patient outcomes for individuals with …
The Effectiveness Of Targeted Education On Improving Nurses’ Self-Efficacy In Caring For Psychiatric Patients On Medical Surgical Units, Rachel Shirey
The Effectiveness Of Targeted Education On Improving Nurses’ Self-Efficacy In Caring For Psychiatric Patients On Medical Surgical Units, Rachel Shirey
Doctor of Nursing Practice Scholarly Projects
Individuals with mental illness are occasionally hospitalized on medical units, specifically medical-surgical units. Nurses working on medical-surgical units may find patients with mental illness more challenging due to the complexity of care they sometimes require. Nurses’ perceived ability to provide quality care for these patients is reduced in comparison to their perceived ability to care for patients without mental illness. Consequently, low self-efficacy can result in the provision of a lower quality of care for this population. The purpose of this quality improvement project was to improve the care that patients with mental illness receive while hospitalized on medical-surgical units. …
Increasing Awareness, Understanding, And Support For Healthcare Second Victims Through The Creation And Distribution Of An Infographic For Leaders And Executives, Theresa Reed
Doctor of Nursing Practice Scholarly Projects
Second victim syndrome describes the constellation of symptoms suffered by healthcare clinicians because of the stresses of caregiving, experiencing adverse patient outcomes, and the increasing pressures of the care environment. The occurrence of second victim syndrome (SVS) in nurses is well supported in literature, along with resultant effects on patient safety, organizational culture, and the organization's financial outcomes. The interconnectedness of nurses with patients is undeniable, and relational impacts can be both profound and enduring. Burnout and stress, manifested by mental, psychological, and physical effects, are possible and may affect the ability of the nurse to provide effective nursing care …

Who Says Women Can’T Love And Empower?: How Representations Of Women Have Progressed In Medical Romance Fiction, Diana Neely
Who Says Women Can’T Love And Empower?: How Representations Of Women Have Progressed In Medical Romance Fiction, Diana Neely
Honors Theses
Throughout history, the representation of women in medical romance fiction has changed with the times. While an individual assumption can be pulled from different time periods, a chronological analysis of Doctor Zay, Promise the Doctor, A Princess in Theory, and The Love Hypothesis was conducted to show the changes of women’s empowerment, but also how women’s empowerment has stayed the same through the medical romance genre. A historical analysis was done to incorporate background information on what was going on during those times along with bridging the gap between the medical romance novels.
Standardized Handoffs For Anesthesia Students, Shawn Barkalow, Noah Prebish
Standardized Handoffs For Anesthesia Students, Shawn Barkalow, Noah Prebish
Doctor of Nursing Practice Scholarly Projects
Communication between healthcare providers is an essential aspect of caring for patients. Effective communication is vital during the patient handoff process. The patient handoff process involves exchanging patient’s medical information between a provider currently caring for the patient and the provider assuming care of the patient. If the information exchanged during the handoff process is inaccurate or essential information is omitted, that could potentially lead to harmful consequences for the patient. Currently, no standardized handoff tool exists for student registered nurse anesthesia students (SRNAs) in clinical practicum at the local level one trauma center. The lack of a standardized handoff …
Breastfeeding After Maternal Anesthesia: A Guideline Development, Megan Berens
Breastfeeding After Maternal Anesthesia: A Guideline Development, Megan Berens
Doctor of Nursing Practice Scholarly Projects
Postoperative breastfeeding recommendations for lactating mothers by anesthesia providers are inconsistent and often inaccurate. Inappropriate recommendations have led to withholding of breastmilk to the infant, unnecessary disposal of breastmilk, surgical delay, exposure of an infant to high levels of drugs in breastmilk, and early cessation of breastfeeding. The purpose of the scholarly project was to develop a set of evidenced-based practice guideline recommendations and a proposed implementation plan for anesthesia providers to use in support of breastfeeding mothers who recover from surgery. Many studies in the literature indicate that there are inconsistencies in postoperative breastfeeding recommendations by anesthesia providers. When …

Development And Implementation Of An Ultrasound-Guided Peripheral Intravenous Catheter Insertion Training Program For Student Registered Nurse Anesthetists, Nicholas Colangelo, Zachary Wise
Doctor of Nursing Practice Scholarly Projects
The American Association of Nurse Anesthetists (AANA) has defined the scope of nurse anesthesia practice to include services in acute, chronic, and interventional pain management, as well as the use of ultrasound (U/S) and other diagnostic technologies. However, there are no standard curriculum requirements in place that mandate graduate programs to educate student nurse anesthetists in U/S-related modalities. In addition to the AANA, the use of U/S in nurse anesthesia practice has recently been adopted by The Council on Accreditation of Nurse Anesthesia Educational Programs (COA), which characterizes U/S use by its clinical impact on the reduction in complications, increased …

Analysis Of Current Practices In Prehospital Congestive Heart Failure Care And Protocol Development To Prevent Readmission., Ayushma Neupane
Doctor of Nursing Practice Scholarly Projects
Congestive Heart failure patients have the highest readmission rate within 30 days of discharge placing a significant burden on healthcare costs and quality of life for the patient and families. Community Emergency Medical Services are the first to respond to moderate to severe exacerbation of Congestive Heart Failure (CHF) patients’ calls. Involving Emergency Medical Services in a preventive approach rather than just responding to exacerbation calls has proven to be effective in pilot studies to prevent heart failure readmissions. The purpose of this Scholarly project was to develop evidence-based recommendations for community Emergency Medical Services’ involvement in the management of …

Addicted To The Beloved? - A Comparison Of Craving For And Attention To The Beloved, And Vape Stimuli, Oluchi Onyegbula, Caitlyn Harriman, Sandra Langeslag
Undergraduate Research Symposium
People who are in love seem to be addicted to their beloved. People who are in love have attentional biases for the beloved and people who are addicted have attentional biases for the substance they are using. This raises the question of how similar craving and attention are for the beloved and an addictive substance. However, there are no studies that directly compared craving and attention to the beloved and addictive stimuli. The aims of the current research were to directly compare subjective emotional experiences and sustained motivated attention for the beloved and vape stimuli, in people who are both …
Exploring The Effect Of Sexual Identity And Social Support On Drinking Habits Among College Students, Emily Shelton, Ryan Carpenter
Exploring The Effect Of Sexual Identity And Social Support On Drinking Habits Among College Students, Emily Shelton, Ryan Carpenter
Undergraduate Research Symposium
This study examines the effect of sexual identity status and social support on drinking habits among college students, focusing on the frequency of alcohol consumption.
Unlike previous research that primarily emphasizes the impact of discrimination on drinking behaviors among sexual minority individuals, this study examines the role of social support. We hypothesize that social support serves as a protective factor, buffering the relationship between sexual identity status and alcohol consumption frequency. Using a series of self-report questionnaires, college students were asked to report their perceived social support (PSS), demographic characteristics, alcohol use frequency, and binge drinking habits.
Results from linear …

Investigating The Nectar Preferences Of Bumblebees While Foraging: Are Total Responses A Good Metric?, Alexander Entwistle, Becky Hansis-O'Neill, Aimee Dunlap Dr
Investigating The Nectar Preferences Of Bumblebees While Foraging: Are Total Responses A Good Metric?, Alexander Entwistle, Becky Hansis-O'Neill, Aimee Dunlap Dr
Undergraduate Research Symposium
The declining population of bumblebees worldwide poses an unmistakable threat to ecological systems and biodiversity. Therefore, a deep understanding of the factors at play when bees are foraging is crucial to conservation efforts. This research aims to explore the energy that foraging bumblebees are willing to expend at a known food source after the food has stopped, and if these responses reveal sugar concentration preferences. In this experiment a novel approach was used, adapted from psychology research on addiction, to measure bee’s preferences for different concentration of sugar-water (nectar). First, how many rewards the bees earned if they were given …

Green Synthesis Of Glutethimide Intermediate Via Nash Reaction, Zahria Patrick
Green Synthesis Of Glutethimide Intermediate Via Nash Reaction, Zahria Patrick
Undergraduate Research Symposium
The purpose of my research project is to utilize green chemistry principles to synthesize an intermediate for Glutethimide, a drug used to treat patients with insomnia. Many pharmaceutical processes require the use of halide-containing chemicals which are harmful to the environment when discarded as waste. Not only does this waste affect the quality of drinking water and aquatic life, but it affects the economy as well. The cost of waste disposal increases with the increasing difficulty of treating it and thus raises the cost of production for pharmaceutical companies.
The reaction of choice is a nucleophilic aromatic substitution of hydrogen, …

Does A Bumblebee’S Size Influence Foraging Behavior?, Alametta Thompson-Hinton, Becky Hansis-O'Neill, Aimee Dunlap Dr
Undergraduate Research Symposium
Current studies of Bumblebees (Bombus impatiens) have shown that they prefer plants that have a higher concentration of sugar over those that are of a lower concentration. However, there is little research analyzing the impact of the size difference amongst bumblebee foragers. During our experiment, we tested if larger bumblebees demonstrate a propensity to pursue nectar rewards more frequently compared to smaller bees. We hypothesized that the smaller bumblebees would forage less than the larger ones under a fixed ratio and three different sugar concentrations. We found that our hypothesis was partly correct: smaller bees initially earned fewer rewards, …

Simulating Mass Extinctions In An Agent-Based Evolutionary Model, Emily Vastola, Will Hayes, Joe Milliano, Tyler Hanke, Ian Heye, Dawn M. King, Sonya Bahar
Undergraduate Research Symposium
In an agent-based model of evolutionary dynamics which has been shown to undergo a nonequilibrium phase transition from extinction to survival, we apply coalescent theory to investigate the responses of population lineages to simulated mass extinctions. In the model, organisms reproduce via assortative mating on a neutral fitness landscape; parameters including the mutability (distance offspring may be distributed away from their parents in the fitness landscape) and the death parameter (percentage of organisms randomly removed during each generation) control the phase transition. Lineage structure can be characterized using the time to most recent common ancestor (TMRCA). We examine how this …

A Spatial Analysis Of Food Access Within Saint Louis City By Walking, Public Transit, And Personal Vehicles., Nicole Eanes
Undergraduate Research Symposium
According to The United States Department of Agriculture, 44 million Americans, including 13 million children, are food insecure as of 2022. Many factors contribute to inadequate food access and food insecurity, including poverty, unemployment, low wages, historical redlining, and structural racism.
As a city with minimal thoroughfares that are safe to walk along and an often unreliable or time-consuming public transit system, I wanted to visualize how the mode of transportation impacts a resident’s access to food in Saint Louis City.
Based on my findings, the Saint Louis Metro Bus System provides the most access to residents in Saint Louis …

Assessing Within-Field Variation In Alfalfa Leaf Area Index Using Uav Visible Vegetation Indices, Keegan Hammond, Ruth Kerry, Ryan R. Jensen, Ross Spackman, April Hulet, Bryan G. Hopkins, Matt A. Yost, Austin P. Hopkins, Neil C. Hansen
Plants, Soils, and Climate Faculty Publications
This study examines the use of leaf area index (LAI) to inform variable-rate irrigation (VRI) for irrigated alfalfa (Medicago sativa). LAI is useful for predicting zone-specific evapotranspiration (ETc). One approach toward estimating LAI is to utilize the relationship between LAI and visible vegetation indices (VVIs) using unmanned aerial vehicle (UAV) imagery. This research has three objectives: (1) to measure and describe the within-field variation in LAI and canopy height for an irrigated alfalfa field, (2) to evaluate the relationships between the alfalfa LAI and various VVIs with and without field average canopy height, and (3) to …
