DePaul Discoveries

Pharmaceutical contaminants in water are becoming increasingly prevalent. This could have potentially harmful effects on human health and aquatic environments, even at low concentrations. Acetaminophen, the active ingredient of Tylenol ®, was the target compound for this study, and the aim was to determine is presence and concentration in various aquatic samples in and around the city of Cádiz, Spain. It was predicted that acetaminophen would be detected in low concentrations in river water, drain outflow, University of Cádiz saltwater flow, and lagoon water, but undetectable in the University of Cádiz sink water and fountain water. The presence and concentration …

Spatial And Temporal Analysis Of Pm 2.5 Concentrations In Chicago Along The Lakefront Trail Using Wearable Air Quality Sensors, Jacob A. Johnson

DePaul Discoveries

Mass urbanization and transportation practices have resulted in high amounts of air pollution. Air pollution can have detrimental effects on human health causing respiratory issues as well as other health complications. Certain areas of cities experience more exposure to air pollution which can also cause them to have more health issues and lower life expectancy. These areas are often associated with disinvestment and minoritized communities of color. This research explores patterns of air quality related to environmental justice areas using low-cost wearable air quality monitoring sensors attached to a bicycle. Data was collected along the Lakefront Trail stretching from Irving …

A Seasonal Decomposition Comparison Between Forest And Turf Habitats: Implications For Climate Change, Amanda Shirmer

DePaul Discoveries

Decomposition is an essential ecosystem service in which microorganisms breakdown organic matter. This process improves soil health and acts as a vital step in global carbon cycles. In this study, we examined decomposition rates and associated soil properties in turf and forest habitats across summer and fall seasons in order to determine how land management practices and climate change may be altering local decomposition regimes. Our study determined that there was a statistically significant difference between decomposition rates in turf and forest ecosystems (P=0.003) and a significant difference in decomposition rate across season (P

Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …

The Impacts Of Urbanization On Soil: The Effect On Decomposition Rates And Microbial Communities, Maximus C. Halekakis

DePaul Discoveries

The anthropogenic impacts of industrialization have left many ecosystems polluted. Soil, being an imperative actor for ecosystem functions, is important to observe under anthropogenic change. My study examined soil organic matter decomposition, microbial biomass carbon(MBC) and the fungal to bacteria ratio(F:B) across an urban-suburban-exurban landuse gradient in San Luis Obispo, California. A cotton strip assay as well as microBIOMETER® testing was performed on three geographic locations in and outside of the city. The cotton strip decomposition acts as an indicator for organic matter breakdown as microorganisms break down the cellulose in the strips causing them to lose mass and tensile …

Disentangling Drivers Of Metacommunity Structure For Small Mammals Throughout Paraguay, William T. Szromba

DePaul Discoveries

Paraguay is home to a unique precipitation gradient, receiving progressively more precipitation from east to west. It has previously been suggested that metacommunity structures for order Chiroptera assemble along precipitation gradients such as this one. Metacommunities have also been shown to assemble along other bioclimatic gradients such as temperature. This study seeks to expand upon other findings by using a larger dataset, partitioned bioclimatic variables, and more mammalian orders. It also seeks to determine how metacommunities assemble along this gradient in Paraguay, investigate the differences between different ecological metacommunity assemblages, and to further understand which bioclimatic variables have the greatest …

DePaul Discoveries

This study examined a novel data source: the contents of letters that students wrote to local, state, or national politicians about gun control for a class assignment in order to collect evidence of the impact of direct and indirect gun violence on the lives of DePaul students. For the study, we coded and analyzed 83 de-identified student letters for themes pertaining to the experience of exposure to gun violence and mass shootings. Our findings include a high prevalence of student exposure to direct incidences of gun violence; strong negative emotions surrounding the fear of gun violence intruding into students’ daily …

Increasing The B-Chromatic Number Of Complete Bipartites By Deleting Edges, Daniel Gawel

DePaul Discoveries

A b-coloring of a graph, G=〈V,E〉, is a proper coloring in which each color has at least one vertex that is adjacent to every other color. The b-chromatic number for G, denoted φ(G), is the largest number of colors you can use to make a b-coloring. For most graphs, φ(G), is around the m-index, an upper bound for φ(G) based on the graph's degree sequence. However, for the complete bipartite graph K_m,n, φ(K_m,n)=2 even though the m-index can be arbitrarily large. In this paper …

Exploring Total Graphs Of Complete Bipartite Graphs, Dominic L J Morgan

DePaul Discoveries

In a proper vertex coloring for a graph G, we call a vertex a b-vertex whenever this vertex is adjacent to at least one vertex of every color class. The b-chromatic number of a graph is defined to be the greatest integer k such that there exists a proper coloring on the graph with k colors where there is at least one b-vertex in every color class. This paper is on the b-chromatic number of the total graphs of complete bipartite graphs. We find bounds of the b-chromatic number for the total graphs of complete bipartite graphs and provide …

The B-Chromatic Number Of Super Cycles, Blair E. Johnson

DePaul Discoveries

The b-chromatic number, a characteristic studied in graph theory, was introduced less than 25 years ago, and while some statistics have been gathered of its properties, the b-chromatic number has yet to be explored in many graphs and circumstances. Before the Undergraduate Summer Research Program, I had no exposure to graph theory, let alone b-colorings. Throughout the program, I developed a fundamental understanding of the subject and began to pursue my own research inquiries. While this objective was difficult to attain at the beginning, I learned strategies and methods to hone my ability to delve into different graphs, and soon …

B-Chromatic Number Of The Graph Power Of The Star Graph, Erik Dahlen

DePaul Discoveries

In this paper we focus on the newly introduced b-colorings of a graph G. A b-coloring is a proper coloring such that for each color class, there exists at least one vertex which is adjacent to every other color. The b-chromatic number of a graph G is the largest number k such that G admits a b-coloring with k colors. This paper will introduce the b-chromatic number of some interesting graphs. Several operations of graphs are defined, and the b-chromatic number of those operations are found. All graphs in this paper are simple, connected, …

Framing The Path To Fitness: Age Differences In Response To Framed Exercise Messages, Iliya Sherif, David B. Taullahu, Alyssa R. Minton, Joseph A. Mikels

DePaul Discoveries

Physical activity is one of the most protective health behaviors one can engage in, yet 75% of active adults in the US, meaning those who exercise regularly, fall short of the recommended levels of physical activity, with an even greater percentage of older adults living inactive lives, meaning they exercise minimally and engage in prolonged sedentary behavior (CDC, 2019). The goal of the current study was to explore different types of message framing targeted at encouraging older and younger adults to exercise. We recruited older adults (n = 184; Mage = 69.45 years, age range: 65- 80 years) and younger …

Developing A Connection To Nature: The Role Of Pet Ownership In Childhood, Alexia Barrable, Samantha Friedman

People and Animals: The International Journal of Research and Practice

Connection to nature is associated with a range of benefits to well-being in both childhood and adulthood. Childhood experiences seem to play a big role in how adult nature connection develops. Among the many predictors of higher connection to nature, relationships with animals, including pets, likely play an important role in facilitating feelings of closeness with nature. In this paper we present two survey studies, one of children (n = 64, age = 6–16 years) and one of adults (n = 356, age = 18–80 years). Our aim was to find out if children who own pets have …

Background and objectives: Coronary heart disease (CHD) is one of the most prevalent diseases worldwide. The primary risk factor for coronary heart disease (CHD) lies in the presence of hypertension, elevated levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein (LDL) in the bloodstream. Furthermore, a reduction in high-density lipoprotein (HDL) levels is linked to an elevated risk of cardiovascular disease-related mortality.

The current retrospective study was undertaken to evaluate the alterations in the lipid profile of patients with CHD.

Methods: The current survey involved collecting data from 867 patients diagnosed with acute or severe CHD, with an …

Mercury’S Shadow: The Pharmaceutical Sources Of Hysteria, Claudia Stokes

English Faculty Research

This essay reconsiders the nineteenth-century epidemic of hysteria in the context of common pharmaceutical practice. Examining the health records of industrial workers, Civil War soldiers, and such prominent figures as Abraham Lincoln, Louisa May Alcott, and Harriet Beecher Stowe, this essay argues that hysteria in its distinctive nineteenth-century manifestation was the result of mercury poisoning. Physicians throughout the nineteenth century commonly prescribed mercury treatments for everything from teething and diaper rash to dysentery and syphilis. Nineteenth-century Americans were habitually exposed to mercury, and yet physicians did not recognize the symptoms of chronic mercury poisoning, which included numbness and paralysis of …

Designing Self-Management For And With Persons Living With Dementia Osullivan, Dympna, Dympna O'Sullivan, Michael Wilson, Damon Berry, Orla Moran, Siobhan O,Neill, Ciaran Nugent, Jonathan Turner, Julie Doyle

Articles

Promoting high quality of life for persons living with dementia has emerged as a central goal in global public health agendas. The emphasis has shifted from extending life to actively enhancing overall well-being by postponing or preventing additional disability. This represents a departure from traditional medical perspectives on dementia to a more socially-oriented approach, placing a strong focus on wellbeing.

In parallel, the concept of self-management for people with living dementia has emerged, where this is a person-centred approach in which the individual is empowered and has ownership over the management of their life and condition. Practice recommendations for person-centered …

Improving Identification Of Complicated Alcohol Withdrawal Syndrome Using The Prediction Of Alcohol Withdrawal Severity Scale, Kristin Hagopian

Dissertations

Problem: Individuals who drink alcohol excessively are at great risk for alcohol withdrawal syndrome (AWS) when hospitalized. Symptoms and their severity differ for everyone, and research shows that the identification and treatment of AWS is challenging and often inadequate. Mild AWS is often overtreated, while moderate to severe AWS is often underdiagnosed and undertreated, placing individuals at risk for longer hospital stays, more time needed in critical care units, and a variety of unintended consequences.

Methods: This evidence-based practice project had a pre-post intervention design in which the Prediction of Alcohol Withdrawal Severity Scale (PAWSS) was implemented to promptly identify …

Implementation Of Home Blood Pressure Monitoring, Sarah Gutzke

Dissertations

Approximately 48.1% of adults in the United States have high blood pressure. Providers may encourage patients to monitor and log their blood pressure at home. Still, patients often fail to bring this information to appointments, leading to reliance on less comprehensive in-office measurements. This quality improvement project aimed to increase adherence to home blood pressure logs using a Blood Pressure Toolkit. A descriptive, observational design was utilized to record patient adherence of taking home blood pressure measurements and increase the number of patients who brought their blood pressure logs to their healthcare provider visits over two months. A convenience sample …

Bridging The Gap: Psychopharmacologic Education And Side Effect Screening For Non-Prescribing Mental Health Professionals, Elaine Fitzgerald

Dissertations

Abstract

Problem: The United States is experiencing a growing demand for pediatric mental health support. Surges in mental health diagnoses and psychotropic medication prescriptions have occurred, compounded by a shortage of psychiatric providers. Non-prescribing mental health professionals are well-positioned to recognize psychotropic medication side effects. However, psychologists and counselors lack formal pharmacology education.

Methods: The quality improvement (QI) initiative was guided by the Plan-Do-Study-Act (PDSA) model. The evidence-based psychopharmacologic education for non-prescribers utilized a quasi-experimental pre- and post- test design. Data collected from clinicians included knowledge, confidence, and skill concerning psychotropic medications. The Psychotropic Medication Monitoring Checklist (PMMC) screen clients …

Improving Mental Health Outcomes For Amputees, Zachary Elmore

Dissertations

Problem: depression, anxiety, and other mental health disorders are more commonly diagnosed in the amputee population related to changes in mobility, activities of daily living, and quality of life (Turner et al., 2020.) As the amputation population is projected to reach over 3 million Americans in the next 25 years, additional screening is imperative to identify patients at high-risk for mental health deterioration (Ziegler-Graham et al., 2018).

Methods: this was a project that included screening all patients with the Personal Health Questionnaire for Depression (PHQ-8) meeting the inclusion criteria of being admitted to 7500 Vascular Surgery at Barnes-Jewish …

Restraint Reduction Using The Brøset Violence Checklist, Deanna Kappelmann

Dissertations

Abstract

Problem: Patient aggression, restraint usage and assaults against healthcare workers have numerous negative health outcomes. Patient aggression and restraint usage on inpatient psychiatric units can be identified early with imminent violence predicative tools such as the Brøset Violence Checklist (BVC), where patient de-escalation interventions can subsequently occur.

Methods: This quality improvement project was conducted using a cohort design with a retrospective and prospective chart review. The IHI PDSA model was used for this project. The BVC was administered to male and female patients ages 18 to 64 years old on the adult inpatient psychiatric unit during the implementation period. …

Depression Screening And Education For Immigrants To Increase Access To Care, Viktoriya Ivantsova

Dissertations

Abstract

Problem: Immigrants are at risk for developing mental health disorders due to multiple factors including social, cultural, or economic factors. This can result in a lower quality of life and an increased chance of further disabilities. Although immigrants are at increased risk for the development of mental health disorders, studies show that utilization of available services and resources are low. Additionally, organizations that provide services to immigrants may not be implementing screening and psychoeducation.

Methods: This quality improvement (QI) project followed a descriptive, observational design along with an educational intervention. Using convenience sampling for recruitment, Russian and/or Ukrainian adults …
