  • EFFECTS OF DEVICE-GUIDED BREATHING TRAINING AFTER MYOCARDIAL REVASCULARIZATION

    Bailey, Fiona; Soria, Sebastian (The University of Arizona., 2023)
    Background: Myocardial revascularization is a common surgical intervention for those with coronary artery disease (CAD). However, for individuals who undergo this procedure, there is considerable risk for developing post-operative pulmonary complications (PPCs). Results of some studies suggest device-guided breathing training may prevent PPCs in this population. Purpose: To investigate the effects of device-guided (resistive vs. non-resistive) breathing training on key post-operative outcomes; length of stay (LOS), maximal inspiratory pressure (MIP), peak expiratory flow (PEF), and six-minute walk test (6MWT). Methods: Databases including PubMed, Google Scholar, Ovid MEDLINE, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, EBSCOhost CINAHL Plus with Full Text, and Scopus were searched to identify and retrieve all relevant references. In addition to direct source searching, references in the bibliographies of key articles and review articles also were reviewed to identify relevant studies. The Physiotherapy Evidence Database (PEDro) scale was used to evaluate each study for quality and risk of bias. Results: Twenty-one studies were identified for inclusion. Resistive breathing training resulted in no change in MIP [4 studies; n=154; SMD=0.01 (95% CI: -0.66, 0.69)] and a small decrease in LOS [4 studies; n=154; SMD=0.19 (95% CI: -0.42, 0.80)]. PEF and 6MWT were not analyzed due to insufficient number of studies. There was no effect of non-resistive breathing training on any parameter. Conclusions: Short-term resistive breathing training shows no benefit for MIP, and minimal benefit for LOS. Importantly, resistive breathing training performed pre-operatively is more effective in improving LOS and MIP compared to post-operative training. Further, low levels of resistive breathing training (i.e., <40% MIP) have no effect on either MIP or LOS. Additional research to compare pre-operative, post-operative versus pre- and post-operative interventions strategies is warranted.
  • SRC KINASE PLAYS A SEXUALLY DIMORPHIC ROLE IN THE MECHANISM UNDERLYING INTERMITTENT FASTING ENHANCED OPIOID ANTINOCICEPTION

    Streicher, John; Seekins, Caleb Alan (The University of Arizona., 2023)
    With its variety of positive reported effects, intermittent fasting was previously hypothesized to decrease negative outcomes associated with opioids. Ultimately, intermittent fasting combined with opioid therapy was shown to increase the antinociceptive effect of the opioids while decreasing the negative side effects, including abuse liability (1). In this study we thus attempted to elucidate the mechanism behind this enhancement of opioid antinociception by intermittent fasting. Proteomics was first performed in the spinal cord and significant differences in Src inhibitor 1 (Srcin1) was found between fasted and ad libitum mice, suggesting a role for Src kinase in this pathway. Western blotting was conducted, the results of which confirmed that in spinal cords Src kinase phosphorylation was increased by intermittent fasting. Next, Src inhibitor was administered to opioid treated fasted mice, which showed that enhanced opioid antinociception was abolished in male mice but not females. This sexually dimorphic effect was supported by immunohistochemistry, which showed that only in intermittent fasted opioid stimulated male mice, Src phosphorylation was greatly increased in the dorsal horn. Finally, colocalization was performed, though these results are preliminary, and no significant results have currently been found. Ultimately, these results suggest that decreased Srcin1 levels cause an increase in Src phosphorylation, regardless of sex, following intermittent fasting. Following opioid treatment, the dorsal horn of intermittent fasting male mice has increased Src phosphorylation that mediates enhanced antinociception. This has uncovered a role for Src kinase in intermittent fasting and opioid antinociception, as well as sexual dimorphism seen in both.
  • DRIVERS OF ALTITUDINAL MIGRATION IN UNGULATE SPECIES

    Alston, Jesse; Satterfield, Paige Alyse (The University of Arizona., 2023)
    Migration is extremely important both at the species and ecosystem level, however most research has focused on long-distance migrations. Without an understanding of short-distance migrations, like altitudinal migration, it can be hard to predict how species will be affected by rapid changes in the environment. Migratory ungulates are of special conservation importance as many are keystone species, having significant effects on ecosystem processes. In this study, I provide an overview of the drivers of altitudinal migration in ungulates and discuss its importance in ecology and conservation. Through a review of case studies of various ungulate species, I found four drivers of altitudinal migration: forage quality and quantity, predator avoidance, weather, and pest avoidance. While a pattern of forage quality and quantity emerged as one of the main mechanisms underlying altitudinal migration, most migrations were driven by a combination of the four factors. This knowledge helps better our understanding of altitudinal migration in ungulates, however more research is needed on how climate change, habitat fragmentation, and other environmental factors influence these species. I conclude by discussing future research directions for the study of altitudinal migration in ungulates and how these can be conducted.
  • STUDENT OUTCOMES BASED ON PERCEPTIONS OF TEACHER QUALITY

    Hunter, Martin; Murdoch, Jack (The University of Arizona., 2023)
    In this paper, we examine the effects of student perception of teachers on long term student outcomes. Using data from the National Longitudinal Survey of Youth with nearly 9,000 observations, we construct three multiple linear regression models with dependent variables: income, natural log of income, and highest grade completed regressed against student ratings of their teachers along with several relevant demographic variables. We find that students who rated their teachers highly were more likely to have a higher income later in life. Having a teacher perceived as bad had no statistically significant effect on long term income. Students who rate their teachers highly complete more years of education on average and those who rate their teachers poorly complete less years of education on average. These findings lead us to conclude that the quality of a school’s teachers matters in the long run for a student’s success both academically and financially.
  • TEACHING ASSISTANTS ON THE FRONT LINES: A STUDY OF A COMPUTER SCIENCE DEPARTMENT'S PROGRAM

    Lewis, Russell; Ioane, Kapua (The University of Arizona., 2023)
    The Undergraduate Teaching Assistant (UGTA’s) Program within The University of Arizona’s Computer Science Department has been wildly successful over the past half decade. With more than 1200 undergraduate students, class sizes, especially at the introductory level, can be quite large. UGTAs are a crucial resource to both students and professors in these larger courses. However, the program faces challenges and has the potential to grow - most notably in its need for training the UGTAs when they are first hired and the need for more flexibility within the job. Improvements aimed at addressing these areas have been developed and launched in the past year. These improvements include a two day training program that newly hired UGTA would be required to participate in as well as a new position for experienced UGTAs to demonstrate growth and experience - both of which were launched in the Spring 2023 semester.
  • INVESTIGATING HOW THE UNEXPECTEDNESS OF A DEATH AFFECTS THE SEVERITY OF GRIEF: A SCOPING REVIEW

    O'Connor, Mary-Frances; Higgins, Cassandra Leigh (The University of Arizona., 2023)
    There is a knowledge gap in grief literature regarding unexpectedness (the perception of unpreparedness for the death of a loved one) being predictive of higher grief severity during bereavement. Many studies that researched grief severity during the COVID-19 pandemic included or found the factor of unexpectedness to be significant. The aims of this scoping review are to discover if the findings of the published literature can conclude that unexpectedness is predictive of higher levels of grief, and if it is a significant factor related to greater bereavement distress from the loss of a loved one due to the COVID-19 pandemic. Using the databases PubMed and PsycInfo, sources were collected and screened for their eligibility to be included in this study. The findings of each study were then extracted based on their relevance, organized, then synthesized. The synthesis of findings can conclude that the unexpectedness of a death is predictive of acute grief and a risk factor for prolonged grief, and that it is a significant factor associated with greater bereavement distress during a pandemic. Experiencing what is perceived to be an unexpected death can predict more severe grief experiences.

  • FROM INCARCERATION TO BEYOND: A LITERATURE REVIEW ON MENTAL HEALTH, TREATMENT, AND REENTRY IN THE INCARCERATED POPULATION

    Langley, Carrie; Fisher, Jamie (The University of Arizona., 2023)
    The United States corrections system is one of the largest psychiatric providers in the country, yet many incarcerated people do not receive adequate mental healthcare during their sentences. When ready to re-enter into society, inadequacies in transitional programs continue to challenge former inmates to maintain sobriety and employment. It is important to mention that many people who have served prison sentences have a history of substance abuse related to mental illness. This literature review aims to discuss current practices and the gaps in continued treatment.
  • SIN MIEDO: A COMMUNITY BASED ART EXHIBITION

    DiCindio, Carissa; Campos, Alexis G. (The University of Arizona., 2023)
    SIN MIEDO explores the theme of Chicanx beauty, aesthetics, culture, and imagery. It is a dialogue between Chicanx community artists from Tucson, myself as the curator, and viewers as they explore this theme through their own experiences, identity, culture, belief systems, and memory. This exhibition and the space utilize a community-centered approach which the exhibition is built around. The work created by the artists guides the conversation and dialogue concerning the theme. While the theme has been provided, each artist has their subjectivity and positionality that allows them to create work that is complex and important to be publicly shown. Sin Miedo encapsulates museum theories and practices of community art, institutional critique, decolonizing the white cube space, and participatory art. Sin Miedo also has an immense focus on the beauty and imagery aspects of Chicanx arts, filtered through a feminist lens, that incorporates those same museum practices and theories. This exhibition is designed to broadcast the voices of Chicanx community artists of Tucson and allow the audience to engage and immerse themselves in the gallery space and theme. Every artist that participates has their own unique story to tell as the Chicanx culture is as diverse as the experiences it brings.
  • THE STUDENT ASSISTANT DIRECTOR'S GUIDEBOOK

    Makino, Yuri; Bussey, Caitlin (The University of Arizona., 2023)
    The goal of this Guidebook is to enable a university film student, with little to no previous experience as an Assistant Director, to fulfill the AD's role on any class project. On any film or TV show, the AD is the event manager of the production, responsible for scheduling, organizing and day-to-day supervision and leadership on the set. The AD is the project's prime communicator and coordinator as they strive to provide their Director, cast, and crew with the maximum resources available within the project’s budget and time limitations. While crucial to any production, the craft of the Assistant Director is rarely taught in university film schools. There is no UA FTV course dedicated to teaching all of the skills needed to be an Assistant Director. Basic budgeting and scheduling are covered in the second semester of the producing course series, but this is an elective that not all students in the program will have the opportunity to take. This Guidebook is a tutorial for those without AD experience, and a reference tool for those looking to improve their performance.
  • DEVELOPMENT OF A QUESTIONNAIRE AND SUBSEQUENT INVESTIGATION OF STUDENT PERCEPTIONS OF PRIMARY PROGRESSIVE APHASIA

    Kielar, Aneta; Abraham, Emily Judith (The University of Arizona., 2023)
    Primary Progressive Aphasia (PPA) is a neurodegenerative disorder characterized by language and communication deterioration in the initial stages of the disease (1-3 years). Given that PPA progresses over the course of years, patients with PPA require interdisciplinary teams of practitioners to provide effective care, including physicians and speech-language therapists. These practitioners should be well-educated about and hold respectful attitudes towards PPA so that patients receive optimal care. The goal of this study was to investigate university students' perceptions of PPA as characterized by both baseline knowledge and positivity of attitude. New scales-- the PPA Knowledge Scale (abbreviated PPAk; assessing knowledge of PPA) and the PPA Attitudes Scale (abbreviated PPAa; assessing attitudes towards PPA)-- were developed for this purpose and administered alongside previously validated scales related to aging and dementia. Pre-health and communication science disorder students were surveyed initially because these students will become the next set of practitioners for patients with PPA. The results indicated that while knowledge of PPA among surveyed students is lacking, attitudes towards PPA are relatively positive. Suggestions for future research include continued evaluation of the PPAk and PPAa scales. There is a need for educational initiatives to provide students with more instruction regarding PPA in the health related fields at the undergraduate level.
  • Exploring How to Improve Professionalism and Engagement During Zoom Learning

    Lee, Jeannie; Hadvani, Kishan; Kim, Ann; Nikolic, Aleksandar; Smith, Jonan; College of Pharmacy, The University of Arizona (The University of Arizona., 2023)
    Objective: To investigate the impact of remote learning on student engagement and professionalism and explore strategies that courses and students used to improve their engagement and professionalism. Methods: Individual structured interviews were conducted with student pharmacists from the class of 2023, 2024, and 2025 using predetermined, open-ended questions. The primary dependent variable was student perceived engagement and professionalism. Students were recruited by e-mail invitations to participate in zoom interviews. Student responses were audio recorded, transcribed, and analyzed via thematic analysis using Delve. Results: Approximately 6% of the students in the eligible cohorts at the University of Arizona College of Pharmacy participated in this study, of which the majority were female (67%) and anticipated to graduate in 2023 (67%). Major themes describing engagement involved active participation, increased distractions with zoom learning, and attendance credit. Major themes describing professionalism involved course camera requirements, Zoom chat etiquette, and speaker muting issues. Common student strategies for engagement involved having a dedicated learning area, writing notes, and staying organized. Common course strategies to increase engagement include Kahoot, quizzes, polls, & breakout rooms. Common student strategies for professionalism included consideration for peers, self-awareness, and professional standing. Common course strategies for professionalism include need for the camera to be on, attendance credit, and in class participation. Conclusions: Most students interviewed stated that interactive learning increased their engagement in online courses. A predominant number of participants reported that remote learning did not impact professionalism of pharmacy students but that camera requirements and chat monitoring could enhance professionalism.
