The Impact Of A Geriatric Trauma Unit On Patient Outcomes, Shannon E. Johnson

DNP Projects

Abstract

Background: Traumatic injuries in the geriatric (> 65) patient population can have devastating effects. Only a small percentage of these patients return to independent ambulation and living. As the population continues to age and life expectancy continues to increase, the incidence of traumatic injuries in geriatric patients will continue to increase. Geriatric friendly hospital wards in several disciplines have been shown to reduce length of stay and improve patient outcomes. However, there has been no research surrounding geriatric trauma wards specifically.

Purpose: The purpose of this quality improvement project was to evaluate the impact of admitting geriatric trauma patients …

Complete High Thoracic Spinal Cord Injury Causes Bowel Dysfunction In Mice, Olivia Wireman, Ellie L. Sams, Lynnet E. Richey, Gabrielle V. Hammers, Andrew N. Stewart, William M. Bailey, Samir P. Patel, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

Bowel dysfunction, is a prevalent and life-impacting comorbidity of spinal cord injury (SCI) with no long-term treatment available. SCI-induced colon changes including motility and fibrosis are understudied as are strategies to address SCI bowel dysfunction. This need remains partly due to the lack of a mouse model that recapitulates the human condition. We hypothesized that a high thoracic spinal transection in mice would trigger bowel dysfunction with coincident colon pathology similar to humans and rats after SCI. We observed bowel dysfunction as increased fecal pellet numbers within the colon, smaller pellet size, and decreased motility. Fecal pellets numbers in the …

Geographic Patterns Of Human Immunodeficiency Virus (Hiv) Risk Behaviors Among Older Adults: A Strategy For Identifying Space As A Risk Exposure, Laneshia R. Conner, Reuben Adatorwovor, Sarah Jane Robbins, Rujeko O. Machinga-Asaolu, Kathryn Showalter, Carrie B. Oser

Social Work Faculty Publications

Objectives: This study examined geographical patterns of HIV risk among adults aged 60 and older.

Methods: The 2019 Behavioral Risk Factor Surveillance System (BRFSS) weighted data was used to analyze self-reported participation in HIV risk behaviors among older adults (n = 62,852). Logistic regression models were used on a dichotomous HIV risk variable to map the distribution of HIV risk behaviors across both census regions and divisions.

Results: The weighted model revealed significance across regions. Across all regions, identifying as female, identifying as Hispanic, and reporting not having depression were protective from participating in HIV risk behaviors.

Design And Comparative Analysis Of Electric Motors With “Flux-Switching” Effect Having Reluctance Rotors And Pm Or Dc Stator Excitation, Oluwaseun A. Badewa, Ali Mohammadi, Donovin D. Lewis, Somasundaram Essakiappan, Madhav Manjrekar, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

This paper introduces innovative designs for synchronous electric motors with phase coils and permanent magnets (PM) or DC-excitation coils embedded in the stator. Alongside concentrated phase coils in dedicated slots, the spoke-type PMs offer high flux intensification, while the option for DC-excitation coils eliminates demagnetization risks. Since the rotor has no active electromagnetic components, the machine can achieve high-speed operation while enabling advanced cooling systems focused solely on the stator. A special implementation with a “wave” or “serpentine” DC-excitation winding which has the potential for reduced losses depending on the motor aspect ratio is presented. The operation, control, and polarity …

Harmonic And Non-Linear Effects On The Parameters And Performance Of A Vernier Machine With Flux Concentrating Spoke Rotor, Ali Mohammadi, Yaser Chulaee, Aaron M. Cramer, Ion G. Boldea, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

This paper presents a systematic study on the MAGNUS machine, which is an innovative dual-stator axial flux permanent magnet vernier machine (AFPMVM). The MAGNUS machine features a novel single-wound dual-stator design with minimal slots and an exceptionally high-polarity spoke-type permanent magnet rotor, which enables a very high flux concentration ratio. The operating principle of vernier machines is derived, showing the possible slot-pole combinations. Inductance components are introduced, and multiple methods are employed to determine the direct and quadrature axis inductances, revealing that despite its spoke-type rotor, due to a high harmonic content and a high differential leakage inductance, the MAGNUS …

Limited research has examined the possible synergistic interrelationships between serious bacterial infections (SBIs) of the heart (i.e., endocarditis), bone, spine, brain, or joints (e.g., osteomylelitis) and hepatitis C virus (HCV) infections. We examined whether syndemic interactions existed between SBI, HCV, and substance-use-related factors in rural communities, hypothesizing that injection-mediated risks elevated the likelihood for both SBIs and HCV infections, which could be exacerbated by synergistic biological–biological or biological and social interactions. We calculated the prevalence ratios (PRs) of past-year SBI associated with each risk factor in separate models. Effect modification among significant risk factors was assessed using multiplicative interaction. Among …

Human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HPV-positive HNSCC) has distinct biological characteristics from HPV-negative HNSCC. Using an AI-based analytical platform on meta cohorts, we profiled expression patterns of viral transcripts and HPV viral genome integration, and classified the tumor microenvironment (TME). Unsupervised clustering analysis revealed five distinct and novel TME subtypes across patients (immune-enriched, highly immune and B-cell enriched, fibrotic, immune-desert, and immune-enriched luminal). These TME subtypes were highly correlated with patient prognosis. In order to understand specific factors associated with prognosis, we used the unsupervised clustering of an HPV-positive HNSCC cohort from The Cancer Genome Atlas …

This communication reviews the matter of the clinical, pharmacological, and regulatory significance of a 4.95 nanogram/ml identification of trichlormethiazide in urine from a horse six days after administration of a compounded trichlormethiazide/ dexamethasone preparation. This combination of dexamethasone and trichlormethiazide has historically been widely used in bovine and equine medicine to reduce local inflammation and edema. The horse was administered an oral formulation of trichlormethiazide 400 mg /dexamethasone 10 mg per packet under veterinary supervision on days 7 and 6 before the race in question. Following the race, the post-race urine sample from the horse tested “positive” for trichlormethiazide at …

Anabolic Properties Of The Progestin Altrenogest And Its Regulation As An Environmental Substance In Horse Racing – Review And Analysis, Andreas F. Lehner, Levent Dirikolu, Sarah Jacob, Kimberly Brewer, Abelardo Morales Briceñoe, Robert Holland, George Maylin, Clara Fenger, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Altrenogest is a progestogen substance used in equine medicine for the synchronization of ovulation during the spring breeding season and the control of estrus in mares. It accomplishes its actions by down-regulation of endometrial progesterone receptors and repression of estrogen receptor transcriptional activation. However, various groups have also measured androgen receptor binding activity for altrenogest in vitro; these findings combined with androgenic and anabolic properties roughly 1/20 in potency of testosterone and its structural similarity to the anabolic steroid trenbolone have created concerns among racing authorities of altrenogest’s potential abilities to alter the outcome of equine athletic performance, even though …

Listening To Cursive: The Roles Of Regional Identity And Folk Beliefs In Perceptual Cue-Weighting, Stella Takvoryan

Theses and Dissertations--Linguistics

Listeners use knowledge acquired from experiences to weight phonetic-level cues to phonological contrasts. Phonetic knowledge is imbued with expectations about the contexts in which cues covary, speakers of a variety, and identity categories or constructs, so it can be challenging to distinguish expectations about variation from expectations about speakers. This study aims to explore the extent that expectations about iconic vowel quality variation in Southern American Englishes can drive cue-weighting. Listeners categorized stimuli with vowel qualities synthesized from an [ɛ]-[eɪ] continuum from a Southern and a non-Southern talker, with duration manipulated in tandem. Half of the participants saw a label …

The Effect Of Fructose Metabolism On Hepatic De Novo Lipogenesis And Adipose Tissue Insulin Resistance, Taghreed Ibrahim Fadhul

Theses and Dissertations--Nutritional Sciences

There is a worldwide epidemic of obesity and metabolic dysfunction. The root cause of obesity is driven by a positive energy balance, which is a consequence of increased caloric intake and decreased energy expenditure. Energy intake is the more dominant force, as increasing energy expenditure is a time-consuming and labor-intensive process. The caloric surplus can be mainly accounted for by increased consumption of high-fat and high-sugar diets. While the risks associated with fat consumption are well-documented, the impact of sugar intake is less understood.

Fructose is a simple sugar widely consumed in modern diets. Its intake has been associated with …

Spermidine And Polyamine Blockade As Key Mediators Of Intestinal Epithelial Cell Functions, Madison Lynn Flory

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Frequently, alterations in the composition of the gut microbiota and its metabolites are linked with intestinal diseases, including inflammatory bowel disease and colorectal cancer. However, the direct connections between alterations in the microbiome and disease states often remain elusive. Prior research has identified increases in both polyamines, which are a class of microbial metabolite, and in the abundance of bacteria that can produce polyamines, in a murine colorectal cancer model. Understanding the significance of the interaction between these microbial metabolites and intestinal epithelial cells (IECs) will provide new and expanded evidence of the importance of the gut microbiome in colorectal …

Common Law Executive Privilege(S), Jonathan Shaub

Law Faculty Scholarly Articles

There are few Supreme Court cases that enjoy as much widespread support as the unanimous decision in United States v. Nixon. The recent pitched battles between Congress and the executive branch have made apparent the vast disagreement between the two branches over access to information. But that disagreement does not extend to Nixon, the unquestioned jurisprudential foundation for the doctrine of executive privilege. Closer inspection shows, however, that this foundation is not a stable one, but one constructed from unnecessary, ill-considered dicta.

As this Article demonstrates, Nixon conflated the constitutional question about one branch’s power vis-à-vis another branch with an …

Visual Legal Rhetoric In The Age Of Generative Ai And Deepfakes: Renaissance Or Dark Ages?, Michael D. Murray

Law Faculty Scholarly Articles

The paradoxical development of visual generative AI tools, such as OpenAI’s DALL-E 3, Midjourney, and Stable Diffusion, simultaneously signals a renaissance and a potential dark age in visual rhetoric and communication. On the one hand, these tools democratize the creation of visual content, empowering attorneys and others to become artists and illustrators of their legal communications without needing to learn how to draw. These AI systems can simplify complex legal concepts, bridge language barriers, and enhance advocacy. But on the other hand, the proliferation of deepfakes presents significant challenges for visual rhetoric. Deepfakes can quickly and easily create realistic but …

West Virginia V. Epa: Considerations For The Future Of Epa Greenhouse Gas Regulation, Shavonnie R. Carthens

Law Faculty Scholarly Articles

When compared to historical levels, the air quality in the United States has improved. However, exposure to air pollution still rises to the top of environmental health risks experienced by Americans. It is estimated that one hundred thousand to two hundred thousand deaths annually are associated with this exposure, which exceeds the deaths from murders and car crashes combined. Further, evidence establishes that “rising concentrations of carbon dioxide, methane, and other greenhouse gases pose serious threats to public health.” Looking to the sources of greenhouse gas emissions, fossil fuel-fired power plants are the largest source of greenhouse gas emissions in …

The Tiny Library And The Mini Library, Reinette F. Jones

Library Faculty and Staff Publications

Ask a librarian to describe a tiny library and a general answer will be a facility that is smaller than a small library. A more contem-porary description is a little library in a small wooden box that is attached to a stand and placed in a neighborhood to support reading and free book exchange. Both are good answers and added to these definitions is the centuries-old backstory when the tiny library was whatever an individual meant for it to be.
