This chapter evaluates the sudden transition from punitive drug enforcement to health-oriented decriminalization, utilizing the 2021 State v. Blake decision in Washington as a …

Flare Guns And Trauma: Patterns, Severity, And Clinical Implications From Case And National Surveillance Data, Ramsay Hafer, Andrew Huff, Lara Phillips

Department of Emergency Medicine Faculty Papers

Flare guns are pyrotechnic devices capable of causing serious injury due to high-temperature combustion and projectile discharge. Though intended for signaling in maritime or wilderness settings, improper use can result in trauma patterns distinct from those seen with typical burns or fireworks. Despite their severity, flare gun injuries remain underreported and poorly characterized. We conducted a scoping review of PubMed, Scopus, and Ovid to identify 12 case reports involving 13 patients, and reviewed US National Electronic Injury Surveillance System records from 2015 to 2024, identifying 18 flare gun-specific injuries for a combined total of 31 injuries. Demographic, injury mechanism, body …

Analysis Of Activated Carbon Fiber (Acf) As Particulate Filtration And Volatile Organic Compound (Voc) Media For The Development Of A Dual-Air Purifying Facepiece Respirator, Brie Mcmahan

ETDs from 2020-2029

Exposure to particulate matter (PM) and volatile organic compounds (VOCs) in occupational or public settings poses adverse health outcomes such as respiratory, cardiovascular, reproductive, neurological, carcinogenic morbidity and mortality. Many occupational settings expose workers to PM and VOC concurrently, yet most commercially available respirators are designed to address either particulates or vapors alone. This includes air-purifying respirators (APRs), powered air-purifying respirators (PAPRs), and filtering facepiece respirators (FFRs) with nuisance-level vapor protection, often limited by bulk, discomfort, high pressure drop, and misuse. We identified a need for alternative dual-exposure media and a respiratory protection device that is lighter, and more comfortable …

Research questions in the study assess EMS responses to suspect opioid overdose incidents from 2019-2023 in Georgia to encompass the following characteristics: timeframe (pre, during, post-pandemic), urban versus rural counties, race/ethnicity, categorical type of first responder, mean dosage of naloxone in milligrams administered, and death. 84,359 records meeting the inclusion criteria were initially retrieved from the …

Improving Awareness And Use Of The First-Responder Alerting Application, Pulsepoint Respond, In The Nursing Profession, Maclaine Matties

DNP Projects

Background/Significance

Out-of-hospital cardiac arrest (OHCA) is a sudden, life-threatening emergency that can occur anywhere and to anyone. In 2023, the American Heart Association identified OHCA as a public health crisis, with survival rates around 10%. Outcomes depend heavily on rapid intervention, as each minute without cardiopulmonary resuscitation (CPR) significantly reduces survival. Mobile phone–based alert systems help bridge the gap between collapse and emergency medical services (EMS) arrival by notifying nearby trained responders. In a county in the Northeast, PulsePoint Respond serves this role. However, despite 1,302 registered responders as of November 2025, only 7 registered nurses were enrolled, highlighting an …

The Effects Of Childhood Maltreatment On Executive Functioning: The Difference Between Cumulative Trauma, Abuse Severity, And Neglect, Kelly Krehbiel

Master's Theses or Doctor of Nursing Practice

Childhood maltreatment is prevalent in the United States with around 558,899 children being victims of abuse in 2022 (U.S Department of Health & Human Services, 2024). Neglect is the most common form of abuse with around 74 percent of abused children being neglected; however, neglect tends to be the least researched form of abuse. Childhood maltreatment has long-term effects on a person’s mental, physical, and cognitive health. Previous research suggests that childhood maltreatment leads to severe deficits in executive functioning skills such as working memory and cognitive flexibility. Executive functioning skills are important for almost every aspect of life including …

“Treatment Not Tents:" The Medicalization Of Homelessness In California’S 2022-2025 Legislative Agenda, Elana R. Straus

Yale Medicine Thesis Digital Library

Modern homelessness emerged in the 1980s due to political choices that cut the social safety net and decreased the availability of affordable housing. Medicalized views of homelessness that frame homelessness as driven by individual pathology, particularly mental illness and addiction, emerged in research, media, and politics at this time. Homelessness has persisted since and remains particularly high in regions, including California, where the housing markets are most constrained. In this context, California advanced multiple legislative changes between 2022 and 2025 that increased pathways to involuntary treatment and criminal-legal control over people experiencing homelessness. In this thesis, I demonstrate how legislators …

Legislative Debate-Attributed Suicidality Among Lgbtq+ Adults: The Buffering Effect Of Community Belongingness, Keith J. Watts, Shawndaya S. Thrasher, Laneshia R. Conner, Nicole Campbell, Louis G. Baser, Dekeitra Griffin, Sydney P. Howard, Missy Spears, Justin X. Moore

Counseling & Human Services Faculty Publications

Background: In recent years, the sociopolitical landscape in the United States has shifted due to an increase in state-level legislation regarding LGBTQ+ rights, a trend that has been particularly pronounced in the Commonwealth of Kentucky. While the mental health impacts of enacted laws are increasingly documented, a critical gap remains in understanding the psychological toll of the legislative debates themselves—the prolonged periods of public discourse surrounding the restriction of rights. Methods: Utilizing data from the 2025 Queer Kentucky Survey (N = 817), this exploratory study examined the association between LGBTQ+ community belongingness and acute suicidality attributed specifically to anti-LGBTQ+ legislative …

Determining Driving Ability Following Traumatic Brain Injury, Shauna M. Corrigan

Occupational Therapy Capstones

Introduction: A traumatic brain injury (TBI) can be a severe injury that causes lasting effects such as visual changes, challenges with concentration and memory, and problems with coordination and balance (Centers for Disease Control, 2024). This can impact an individual’s ability to safely return to the valued occupation of driving. Occupational therapists will commonly assess an individual’s ability to return to drive following a TBI, but they experience challenges in doing so due to a lack of standard method in assessing one’s safety while operating a motor vehicle (Baker et al., 2015; Tamietto et al., 2006; Classen et al., 2009; …

National Consensus On The Capabilities That Inform The Role Of Advanced Practice Paramedics: A Delphi Study, Alessia Restiglian, Lorna Martin, David Long, Louise Reynolds, Tony Walker, Ben Meadley, Ashleigh Finn, Alan Batt, Alecka Miles, Tania Johnston, Brendan Shannon

Research outputs 2022 to 2026

Advanced Practice Paramedics (APPs) are highly skilled paramedics who operate in diverse clinical settings both within and outside traditional ambulance services. International evidence demonstrates that APPs enhance patient outcomes in areas such as critical and primary care. In Australia, the expansion of APP roles and responsibilities has gained momentum; however, no nationally recognised framework exists to define their expected capabilities. This gap leads to inconsistencies in education, practice and role clarity. A standardised capability framework is therefore vital to guide the development, implementation and integration of APP roles within the Australian healthcare system. The primary aim of this study was …
