2020-Current year OA Pubs

BACKGROUND: Gastrointestinal procedures generally require pre-procedural fasting to optimize sedation safety. While the American Society of Anesthesiologists (ASA) recommends no intake of clear liquids and solid food 2-4 and 6-8 hours respectively prior to endoscopic procedures, the actual nil per os (NPO) duration for these procedures in practice is unknown. Our objective was to analyze NPO duration for patients undergoing these procedures and to determine its association with clinical and administrative variables.

METHODS: Inpatient data from 2016-2018 for the three procedures was extracted from electronic medical records and administrative data at a single-center tertiary academic medical center. Various statistical tests …

This systematic review protocol describes our approach to evaluate the incidence of adverse events from the use of ultrasound-guided regional anesthesia by Emergency Physicians as described in the literature. This project will also seek to document the scope of ultrasound-guided regional anesthesia applications being performed in Emergency Medicine literature, and potentially serve as a framework for future …

Internalization Of Appearance Ideals And Not Religiosity Indirectly Impacts The Relationship Between Acculturation And Disordered Eating Risk In South And Southeast Asian Women Living In The United States, Sonakshi Negi, Erik M Benau, Megan Strowger, Anne Claire Grammer, C Alix Timko

2020-Current year OA Pubs

Objective: Studies that examine disordered eating in samples of Asian individuals living in the United States frequently combine all individuals of Asian descent into a single group, which can obscure important differences between groups and their experiences of acculturation. The goal of the present study was to establish the relation of acculturation, internalization of appearance ideals, and religiosity as predicting body dissatisfaction and disordered eating in women of South and Southeast Asian (SSEA) descent.

Method: Women of SSEA descent (

Results: Direct paths from acculturation to both body dissatisfaction and disordered eating were not significant. Thin ideal internalization completely accounted …

The Structural Basis Of Long-Term Potentiation In Hippocampal Synapses, Revealed By Electron Microscopy Imaging Of Lanthanum-Induced Synaptic Vesicle Recycling, John E Heuser

2020-Current year OA Pubs

Hippocampal neurons in dissociated cell cultures were exposed to the trivalent cation lanthanum for short periods (15-30 min) and prepared for electron microscopy (EM), to evaluate the stimulatory effects of this cation on synaptic ultrastructure. Not only were characteristic ultrastructural changes of exaggerated synaptic vesicle turnover seen within the presynapses of these cultures-including synaptic vesicle depletion and proliferation of vesicle-recycling structures-but the overall architecture of a large proportion of the synapses in the cultures was dramatically altered, due to large postsynaptic "bulges" or herniations into the presynapses. Moreover, in most cases, these postsynaptic herniations or protrusions produced by lanthanum were …

Low Cancer Incidence In Naked Mole-Rats May Be Related To Their Inability To Express The Warburg Effect, Pedro Freire Jorge, Matthew L Goodwin, Maurits H Renes, Maarten W Nijsten, Matthew Pamenter

2020-Current year OA Pubs

Metabolic flexibility in mammals enables stressed tissues to generate additional ATP by converting large amounts of glucose into lactic acid; however, this process can cause transient local or systemic acidosis. Certain mammals are adapted to extreme environments and are capable of enhanced metabolic flexibility as a specialized adaptation to challenging habitat niches. For example, naked mole-rats (NMRs) are a fossorial and hypoxia-tolerant mammal whose metabolic responses to environmental stressors markedly differ from most other mammals. When exposed to hypoxia, NMRs exhibit robust hypometabolism but develop minimal acidosis. Furthermore, and despite a very long lifespan relative to other rodents, NMRs have …

What Covid-19 Laid Bare: Adventures In Workers’ Compensation Causation, Michael C. Duff

All Faculty Scholarship

This essay performs a close analysis of workers’ compensation coverage of COVID-19 and arrives at the conclusion that it should not be “impossible” to prove in a legal sense that an employee’s COVID-19 was caused by work. Scientific proof is not the same as legal proof: workers’ compensation law has never required that claims must be supported by irrefutable scientific proof of workplace causation. Yet repeatedly one heard this suggestion during public discussion on workers’ compensation coverage of employees.

Still, there is good evidence that even when workers’ compensation undisputedly covers work-related disease employers seldom pay benefits (and states do …

Krabbe Disease: A Personal Perspective And Hypothesis, Mohammad Rafi

Department of Neurology Faculty Papers

Introduction: Krabbe disease (KD) or globoid cell leukodystrophy (GLD) is one of the lysosomal disorders affecting central and peripheral nervous systems (CNS and PNS). It is caused by mutations on the galactocerebrosidase (GALC) gene. Affected individuals accumulate undegraded substrates and suffer from neuroinflammation. Methods: Hematopoietic stem cell transplantation (HSCT) has been partially successful in treating patients with KD when accomplished prior to the onset of symptoms. The success is credited to the ability of the hematopoietic stem cells in providing some GALC enzyme to the CNS and eradicating potential neuroinflammation. Combination of the HSCT with some other GALC-providing strategies has …

Overlooked And Under-Referred, Gretchen Spencer

Murray State Theses and Dissertations

Abstract

According to the National Association for Gifted Children (2019) up to 10% of the population can benefit from receiving gifted services. Due to wide variability in definition, identification and services offered, the NAGC recognized that gifted students have been and continue to be overlooked (NAGC, 2019). Not only are gifted students under identified overall, the ratio of identified students who are Black, Latine, special education, and female was lower than the ratio in the population and occurred at a significantly lower rate than their white counterparts (Ecker-Lyster & Niileksela, 2017). The issue of underrepresentation within the gifted population has …

The Role Of Glis3 In Zebrafish Endocrine Development And Regeneration, Tasha Swenney

Murray State Theses and Dissertations

Maintenance of proper blood glucose homeostasis is governed by the endocrine cells of the pancreas. Dysregulation of blood glucose is characteristic of the disease, diabetes mellitus. Relatively little is known about the molecular mechanisms that underlie diabetes. The genes associated with more common forms of diabetes remain more enigmatic and likely have less direct roles in blood glucose homeostasis such as glucose sensing, insulin secretion, and β cell maintenance. GLIS3, a transcription factor involved in pancreatic development as well as the transcriptional regulation of insulin has been identified as a risk locus for type 1 and type 2 diabetes …

Formal Ethics Education In Speech-Language Pathology Graduate Students, Jennifer N. Gaylord

Murray State Theses and Dissertations

Ethical service provision is an essential foundational skill for speech-language pathologists (SLPs) and is fundamental for maintaining the integrity of the profession of speech-language pathology. While practicing speech-language pathologists are required to complete formal ethics training during each certification maintenance interval, there are no guidelines set forth as to the amount and type of training for graduate students in speech-language pathology. This quasi-experimental investigation compared the effect of ethics training embedded within a curriculum to formal ethics training on the ethics knowledge and self-reported comfort levels of first-year graduate students in speech-language pathology. Two equal, non-randomized groups of participants completed …

Finite Index Right-Angled Mock Artin Groups In Right-Angled Mock Reflection Groups, Zachary Marcum

Murray State Theses and Dissertations

Associated to any graph Γ are several groups where their presentations are encoded by Γ. Two such groups are right-angled Coxeter groups and right-angled Artin groups. By introducing more structure to Γ, what we call "local involutions," the graph Γ becomes a right-angled mock reflection system and encodes the presentation of two more groups: right-angled mock reflection groups and right-angled mock Artin groups.

Here we show that every right-angled mock Artin group associated with an n-gon graph with local involutions is a finite index subgroup in some right-angled mock reflection group. We employ a strategy similar to the one Davis …

Synthesis Of Functional Chalcone Library For Use In Aza- Dipyrromethene Dye Systems, Kendal Crawley

Murray State Theses and Dissertations

Over the past decade, Aza-Bodipy dyes (ADPs), a derivative of the extensively studied BF₂-dipyrromethene (BODIPY), have become a growing field of research due to their unique photophysical properties, high yielding synthesis, and relative stability. They possess a unique spectral window of 600 to 750 nm which is the red to near-IR region, evidenced by the blue color of many of these dyes. Increasing interest in these dyes is due to this near-IR window which is important for many applications.^1-4 ADP chromophores also have a common core motif to that of phthalocyanines which allow for coordination at their …

This study sought to investigate potential influences on the prosocial behavior of donating to the homeless. With a rise in both homelessness and dog ownership, this project sought to investigate how the presence of a dog may impact both the willingness to donate and monetary amount donated to a homeless individual. Results indicated a significant three-way interaction between the sex of the homeless individual, the sex of the participant, and the presence of a dog. Overall, the presence of a …

A Personalized Values Intervention To Increase Health Behaviors In College Students, Jessica M Criddle

Murray State Theses and Dissertations

College students in the United States face unique health risks such as problematic alcohol use, poor nutrition, low sleep quality, and low rates of exercise. Research increasingly shows interventions utilizing individualized approaches lead to longer term pro-health behavior change. Values-centered Acceptance and Commitment Therapy (ACT) is a useful framework to for development of personalized, effective interventions. One reason for this may be that impersonalized interventions and researcher-generated target behaviors common in other literatures may not hold the same evocative effect and connection to health behaviors for each or every participant. In ACT, valuing increases the probability of values-consistent behavior, such …

Effects Of Covid-19 Mandates On Student Engagement And Management Of Collegiate Equestrian Teams, Travis Fortune

Murray State Theses and Dissertations

Events like a global pandemic can negatively impact how organizations and groups function.

Barriers To Mental Health Service Use And Preferred Treatment Format Among Racial And Ethnic Minorities, Jasmine Maxwell

Murray State Theses and Dissertations

One of the most pressing concerns in mental healthcare is the limited use of mental health services across the country. Research has indicated that individuals from racial/ethnic minority groups are significantly less likely to seek mental health services, which has led many to examine specific barriers to treatment-seeking. Given research that has suggested that barriers to treatment-seeking may be structural, attitudinal, or cultural in nature, this study aimed to gain a better understanding of the relationship between these barriers and willingness to seek psychological help. Another goal of the current study was to examine the role of online therapy in …
