The Predictive Power Of Social Engagement On Psychological Outcomes Among College Students, Allison J. Gamble

Walden Dissertations and Doctoral Studies

Worsening mental health among college students post-COVID is a growing national health crisis. Grounded in Cacioppo’s evolutionary theory of loneliness and Feeney and Collins’ thriving through relationships theoretical perspectives, the purpose of this study was to explore the degree to which social interaction and social support predicted psychological outcomes among undergraduate students. Survey responses from over 74,000 undergraduate students who completed the ACHA-NCHA survey for Fall 2019, 2021, and 2022 were analyzed. The surveys included the Kessler 6 screening for non-specific mental illness, the Diener flourishing scale, and questions to assess the number of hours spent in categorically-sorted social situations …

Background: Traditional East Asian medicine (TM) is widely used in Korea and other East Asian countries. However, the effects of TM treatment on acute ischemic stroke (AIS) outcomes remain unclear, as previous studies lacked a sufficient sample size, a consecutive series design, or a prospective outcome capture approach. We aimed to investigate whether combining TM with conventional Western medicine (CM) treatments (C+TM) leads to better outcomes after AIS, relative to CM treatment alone.

Methods: We retrospectively analyzed 2157 consecutive patients with AIS from a prospectively collected registry (2011-2021) at our center and compared the CM and C+TM groups in terms …

Molecular Fluctuations Inhibit Intermittency In Compressible Turbulence, Ishan Srivastava, Andrew Nonaka, Weiqun Zhang, Alejandro Luis Garcia, John B. Bell

Faculty Research, Scholarly, and Creative Activity

In the standard picture of fully developed turbulence, highly intermittent hydrodynamic fields are nonlinearly coupled across scales, where local energy cascades from large scales into dissipative vortices and large density gradients. Microscopically, however, constituent fluid molecules are in constant thermal (Brownian) motion, but the role of molecular fluctuations in large-scale turbulence is largely unknown, and with rare exceptions, it has historically been considered irrelevant at scales larger than the molecular mean free path. Recent theoretical and computational investigations have shown that molecular fluctuations can impact energy cascade at Kolmogorov length scales. Here, we show that molecular fluctuations not only modify …

Tumor-Informed Minimal Residual Disease Testing In Select Solid Tumors And Hematologic Malignancies: A Narrative Review, Humza Mallick, Marcus Yoakam, Varun Karri, Samir Dalia

Student Publications

Tumor-informed circulating tumor DNA assays detect patient-specific cancer mutations in plasma and hold promise for detecting minimal residual disease (MRD) after or during definitive therapy. Recent large studies across solid tumors and hematologic malignancies suggest that tumor-informed MRD (TI-MRD) is strongly prognostic for relapse and survival. We reviewed disease evidence for these claims, as well as the potential utility in guiding therapeutic decisions. TI-MRD assays consistently achieved high analytical sensitivity. In solid tumors (colorectal cancer [CRC], non-small-cell lung cancer, breast cancer, and bladder cancer), multiple studies demonstrated that post-treatment MRD positivity conferred markedly worse recurrence-free and overall survival. TI-MRD positivity …

Improving Empathy And Reducing Stigmatization In Pre-Clinical Physician Assistant Students Towards Patient Taking Opioids For Chronic Pain: The Feasibility Of A Perspective-Taking Peer Role-Play Intervention, Barbie Ann Seton Stephen

Doctor of Philosophy in Translational Health Sciences Dissertations

Background: Empathy has been identified as a crucial skill for all healthcare providers who treat patients with chronic pain. It has been directly linked to higher patient satisfaction and improved health outcomes. It has also been linked to reduced burnout, fewer medical errors, and improved job satisfaction among healthcare providers. Despite the many interventions that have been developed to promote empathy, the decline of empathy in healthcare providers and trainees continues to be of great concern, especially in pain management and opioid prescribing, thus affecting the quality of care given to these patients. In physician assistant students, this decline has …

Buck, Ashwini Kumar, Rachel Shelley, Simon J. Ussher, Robert Clough, Scott Meyerink, Prema P. Panda, Ashley T. Townsend, Neil Wyatt

School of Geography, Earth and Environmental Sciences

A range of leaching protocols have been used to measure the soluble fraction of aerosol trace elements worldwide, and therefore these measurements may not be directly comparable. This work presents the first large-scale international laboratory intercomparison study for aerosol trace element leaching protocols. Eight widely-used protocols are compared using 33 samples that were subdivided and distributed to all participants. Protocols used ultrapure water, ammonium acetate, or acetic acid (the so-called "Berger leach") as leaching solutions, although none of the protocols were identical to any other. The ultrapure water leach resulted in significantly lower soluble fractions, when compared to the ammonium …

Telehealth Education Leveraging Electronic Transitions Of Care For Copd Patients (Tele-Toc): A Study Protocol For A Type Ii Hybrid Effectiveness-Implementation Randomised, Pragmatic Clinical Trial Of A Pharmacist-Led Intervention, Deepa Ramadurai, Cathryn T Lee, Leah Traeger, Geoff Pucci, Andrea Jackson-Sagredo, Sachin Shah, Joanna Abraham, Vineet M Arora, Valerie G Press

2020-Current year OA Pubs

INTRODUCTION: Transitions of care (TOC) between hospital, ambulatory and home settings for high-risk adults with chronic diseases are complex, costly and often result in poor health outcomes. Suboptimal care transitions lead to medication errors, non-adherence, decreased self-management skills and inadequate follow-up, all of which contribute to readmissions or emergency department visits. The Transitional Care Model aims to address these challenges through patient-centred, in-home interventions. We propose to implement and evaluate TELE-TOC: Telehealth Education Leveraging Electronic Transitions Of Care for Chronic Obstructive Pulmonary Disease (COPD) patients. This study will evaluate the added value of a virtual, pharmacy-based intervention integrated into an …

Fraggin’ The Superhero Genre: Parody And Carnival In Dc’S Lobo, Ryan L. Johnson

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This essay examines the DC anti-hero Lobo as an ideal example of the constructive, creative power of parody and Bakhtinian carnival. Unlike Bakhtin’s assertion that carnival since the Renaissance has lost its spirit of play and become purely destructive, Lobo uses grotesque violence to create just as much as he destroys social norms. Ultimately, the mini-series under consideration provide a valuable tool for students to understand carnival, parody, and its power as criticism.

Evaluating The Pollutant Permeation Index (Ppi) For Regional Air Quality Assessment: A Study Of Los Angeles And California Regions, Jivar Afshar, Arezoo Khodayari, Sina Taghvaee

CSU Journal of Sustainability and Climate Change

Air pollution poses significant challenges by affecting public health, increasing the prevalence of air quality-related diseases, and contributing to climate change. Federal, state, and local governments are implementing various regulations and policies to mitigate these effects. However, assessing the effectiveness of localized air pollution regulations remains complex, often relying on extensive data collection methods, such as emission inventories. This paper introduces the Pollution Permeation Index (PPI), a novel method that simplifies the evaluation of health burdens resulting from pollutant migration between neighboring regions. The PPI method employs straightforward calculations to quantify how pollutants, including Ozone (O₃), fine Particulate Matter (PM …

Solvent Extracts Of Pulvigera Papillosa (Orthotrichaceae) Show No Antimicrobial Properties In Disk Diffusion Tests, Ryan A. Solorzano, Justin Paulin, Grayson Prater, Michael Lanier

Humboldt Journal of Microbiology

Abstract As antibiotic-resistant bacteria become more prevalent, the search for novel forms of antibiotics in the natural world has become an increasingly worthwhile endeavor. Many mosses have been found to contain antimicrobial properties, including those in the family Orthotrichaceae. Pulvigera papillosa, an Orthotrichaceous moss native to California, has thus far not been investigated to determine whether it contains antimicrobial properties. Extraction techniques using polar and nonpolar solvents have proven to be effective in extracting the secondary metabolites that allow mosses to defend themselves against a hostile microbial world. This study takes a preliminary look into the antimicrobial properties of P. …

Assessing Antimicrobial Properties Of Plant-Derived Ellagic Acid Supplements, Noah S. Schuhmann, Andrew Mclaughlin, Julian Barrera

Humboldt Journal of Microbiology

Bacteria present in the human gut microbiota are affected by compounds with antimicrobial properties. Phenolic compounds extracted from plants have been shown to exhibit significant antimicrobial capacity at certain concentrations, which makes them an area of interest to researchers. Ellagic acid is one such phenolic compound, present in nuts and berries that many people consume on a regular basis. Supplements containing concentrated ellagic acid provide an additional source for the compound. It is known that, in the body, ellagic acid is metabolized into urolithins, which contribute to health through their anticancer and anti-inflammatory qualities. In this study, we investigated the …

Comparative Analysis Of Probiotic Viability In Alcoholic And Non-Alcoholic Kombucha, Isabella N. Cerrone, Brooke Pirkle, Danielle Williamson, Gianna Vendrell, Chloe Kraft

Humboldt Journal of Microbiology

Kombucha is a fermented tea beverage valued for its probiotic and antimicrobial properties that arise from complex molecular interactions between yeast, acetic acid bacteria (AAB), lactic acid bacteria (LAB), and metabolic byproducts of fermentation. With the rising demand for non-alcoholic versions of traditionally alcoholic kombucha beverages, ethanol reduction methods have become common, though their impact on probiotic viability and antimicrobial properties remains poorly understood. This study investigates the effects of ethanol removal on kombucha’s functional properties, including probiotic survival, antimicrobial activity, and organic acid composition (pH). We compared alcoholic and non-alcoholic versions of JuneShine kombucha across five flavors. Probiotic viability …

Growth Trends In Abundance And Diversity Of Synthetic Microbial Communities Over Varying Thermal Conditions, Mariska M. Kessler, Jocelyn Wolfinger, Destiny S. Alcaraz

Humboldt Journal of Microbiology

Microorganisms create various communities that act as the foundation of ecosystems. Abiotic factors such as temperature variability and environmental fluctuations are known to produce shifts in the abundance and diversity of microbial communities, but our current understanding is limited. In this study, we aimed to address this gap by observing abundance and diversity growth patterns under different temperature conditions within individual species and communities. Samples of 4 isolates and 4 artificial communities were grown at constant and fluctuating temperatures. Results found that the isolate samples had the highest abundance under constant high temperatures, whereas the community samples had the highest …

Elucidating The Relationship Between Water Quality And Antibiotic Resistance Of Rainwater Microbes Across Western Humboldt County, Theo P. Murphy, Eve Wendley, Justice Laskowski, Tyler Paredes

Humboldt Journal of Microbiology

Limited studies have been conducted regarding the fecal contamination and microbial dispersal through rainwater, with no known studies investigating the potential connection between antibiotic resistant microbes and water quality in rainwater. This study seeks to identify the presence of a correlation between water quality and incidence of antibiotic resistance in rainwater microbes. We hypothesize that there will be a correlation between these two variables. We additionally anticipate a high incidence of fecal contamination across rural and urban collection sites alike, with fecal contamination being more prevalent in rural areas than urban locals. To determine water quality, we measured the concentration …

Comparative Analysis Of Taproot And Fibrous Root System Microbiomes Under Flooding Stress, Natalie S. Kozlowski, Leighanna Jake

Humboldt Journal of Microbiology

There has been increased interest in understanding how the microbiomes of vascular plants respond to flooding stress and, many studies have focused on monocotyledonous plants with fibrous root systems. This leaves a gap in knowledge of dicotyledonous plants with taproot systems, as previous studies have been in the context of flooding to cropland affecting major food crops which are often monocotyledonous plants with fibrous root systems. Since the structural and functional differences between these root systems may influence microbial community stability and response to flooding conditions, a study looking at both is long overdue As such, this study aims to …

Accidental Daily Dosing: Severe Methotrexate Toxicity In A Patient With Rheumatoid Arthritis, Sidra Memon, Kavitha Vemuri, Syed Uzair Mahmood, Darshit Patel

Advances in Clinical Medical Research and Healthcare Delivery

This case highlights a crucial complication of oral methotrexate therapy: toxicity due to dosing errors. A patient’s daily dosing regimen, instead of the intended weekly schedule, led to a significantly excessive cumulative dose of methotrexate over a short period, resulting in severe hematologic and mucosal toxicity. This underscores the importance of clear patient education and vigilant prescription practices to prevent such errors.
