Yardangs are wind-carved linear ridges that are found selectively on Earth and extensively on Mars. The history of the morphologic development of yardangs is not well known. In the Puna high plateau of Argentina there are ignimbrite deposits, many of which have been eroded into yardang fields, commonly called fleets. Yarding fleets are evenly spaced forms, facing into the wind, that resemble a fleet of boats sailing. A prominent fleet, known as Campo de las Piedras Pomez (CCP) was studied to more fully understand their formation and morphology, including field research in December 2018 and 2019. Some physical characteristics looked at in the field included: dedos direction and lengths; heights and lengths of yardangs; structural features; wind and gravel ripple direction. In addition, relationships between yardang organization and structural control have been analyzed. The dedos on the fronts of yardangs averaged 4.0cm in length, while the reverse dedos were 3.3cm. From this it was determined that: Two wind directions, with one dominant, are present; Structural features can shape morphology of yardangs.

A Yarrowing Experience: The Tumor Inhibition and Toxicity of Utah's Native Achillea millefolium

December 30, 0020 12:00 AM
Parada, Michelle (Weber State University)
Faculty Advisor: Schramm, Katharina (Weber State University, Botany)

This research focuses on anti-tumor and the biotoxicity of A. millefollium (yarrow).
Yarrow is an interesting plant with a long history of medicinal uses, but very little has been done to research and prove the different beneficial properties claimed. There are two simple bench-top assays performed in this study, the potato disc assay which inoculates potato slices with Agrobacterium tumefaciens as well as different concentrations of yarrow extracts and assesses the resulting tumor formation and the brine shrimp toxicity assay to assess the LD-50 of the extracts. My results will indicate whether or not the native yarrow extracts inhibit or do not inhibit tumor formation and its toxicity level. The results of this research could lead to further studies of the phytochemicals in the plant to be used for cancer treatments.

Prostate cancer is the second most commonly diagnosed cancer in men, and metastatic prostate cancer is currently incurable. Prostate cancer frequently becomes resistant to standard of care treatments. Moreover, the administration of conventional chemotherapeutic drugs, such as docetaxel (DOC), poses the risk of debilitating toxic side effects. Combination therapy, in which several compounds targeting multiple cellular pathways are administered jointly, is one tool that can be used to combat therapeutic resistance and drug toxicity. Vitamin E (VE) compounds and analogs have been proposed as potential non-toxic chemotherapeutics. We modeled combination therapy using mixture design response surface methodology (MDRSM), a statistical technique designed to optimize mixture compositions, to determine whether combinations of three chemotherapeutic agents (γ-tocotrienol (γ-T3), γ-tocopherol ether acetate (ɑ-TEA), and DOC) would prove more effective than DOC alone in the treatment of PC-3 human prostate cancer cells. A response surface was generated for cell viability, and the optimal treatment combination for reducing cell viability was calculated. We found that a combination of 30 µM ɑ-TEA, 20 µM γ-T3, and 25 nm DOC was most effective in the treatment of PC-3 cells. We also found that combining γ-T3 and ɑ-TEA with DOC decreased the dose of DOC required to significantly reduce cell viability in PC-3 cells. Finally, we found that combining γ-T3 and ɑ-TEA with DOC enhanced treatment efficacy in DOC-resistant PC-3 cells.

Serotonergic Hallucinogens' Antidepressant Potential: A Comparative Review of Serotonergic Hallucinogens and Ketamine

December 30, 0020 12:00 AM
Ouzts, Ethan (Brigham Young University)
Faculty Advisor: Matheson, Rebekka (BYU Family, Home, and Social Sciences; Psychology)

Ketamine was recently approved by the U.S. Food and Drug Administration as a therapeutic approach to treat individuals with treatment-resistant depression. This approval opens the door for other hallucinogens to be approved for psychiatric use. This review compares the antidepressant efficacy and safety of ketamine to serotonergic hallucinogens, such as lysergic diethylamide acid (LSD). Ketamine acts as the standard of comparison in this review. Serotonergic hallucinogens demonstrate similar short to mid-term responses in patients with depression and compares well to ketamine's safety. Researchers should conduct additional randomized, controlled experiments to better establish serotonergic hallucinogens' antidepressant potential. Despite this limitation, serotonergic hallucinogens warrant serious consideration for potential antidepressant treatment.

An Aperture Correction for GeMS MCAO SBF Distance Measurements

December 30, 0020 12:00 AM
Sundstrom, Rebecca; Jensen, Joseph B. (Utah Valley University)
Faculty Advisor: Jensen, Joseph (Utah Valley University, Physics)

We will measure Surface Brightness Fluctuations (SBF) in three galaxies (ESO137-G006, NGC 3309, and NGC 5128) using images from two cameras: the GeMS Multi-Conjugate Adaptive Optics (MCAO) system and the FLAMINGOS-2 (F-2) near-infrared imaging spectrograph, at the 8-meter Gemini South Telescope in Chile. To make an accurate measurement we need to first determine a photometric calibration for the MCAO system by comparing flux, or captured light, from both detectors. This is necessary because MCAO collects crisp, sharp images but omits some of the total incoming flux from the stars in the galaxies. F-2 takes broader images but includes more measurable flux. By finding the ratio of the flux collected by MCAO to the flux collected by F-2 we can take this "missing" light into account without compromising the crisp, sharp resolution MCAO provides.

Vaping: Not a Safe Alternative to Smoking

December 30, 0020 12:00 AM
Morgan Howard, Corinna Trujillo Tanner, Boyd Tanner, Brandon Thatcher, Janelle Macintosh (Brigham Young University)
Faculty Advisor: Trujillo Tanner, Corinna (Nursing, Nursing)

Purpose/Aims: The purpose of this Review of Literature is to present the most current and accurate information about e-cigarette use, or vaping, with recommendations for nursing practice.

Rationale/Conceptual Basis/Background: According to the CDC, to date over 1300 individuals have developed severe lung injury, associated with vaping, including 216 fatalities. Most of these cases involved young people in their teens or twenties. There are concerns that marketing for vaping specifically targets young people and leads potential users to consider the practice relatively safe. On the contrary, vaping is associated with several serious health risks, including lipoid pneumonia, acute respiratory distress syndrome and popcorn lung. Little is known about the effects of the 60+ compounds identified in vaping aerosol, which is inhaled directly into the lungs. Nurses are often the first point of contact for patients in primary care and urgent/emergent settings. Nurses provide valuable patient education, health assessment, and referral. It is important for nurses to have access to the latest information about this developing problem.

Methods: We conducted a review of literature. We reviewed and summarized information from the Food and Drug administration, Centers for Disease Control, American Medical Association, American Academy of Pediatrics, and other reputable sources. All information reviewed had been published within the last six months. Research questions which guided this review sought to identify important considerations for nursing assessment, and nursing interventions.

Findings/Clinical Implications:

Nursing Assessment: An important part of nursing assessment should include documentation of a patient's history of vaping. When a patient presents with respiratory symptoms and has a history of vaping, a detailed vaping history covering the previous 90 days should be obtained. When acute lung injury, caused by vaping is identified, it must be reported to local and state health departments, per the new CDC guidelines.

Nursing interventions should include patient education as follows: 98.7% of "vape juice" assayed by the FDA contained the addictive substance nicotine (even if labeled "nicotine free") Nicotine is highly addictive and damages developing brain tissue in fetuses, infants, children and teens Inhaled "second hand" vape aerosol is dangerous for pregnant women, infants, children and those with lung disease The inhaled solution is not "water vapor" but rather an aerosol created by an electric heating element within the vaping device The inhaled solution contains up to 60 + chemicals including heavy metals

There is no established standard for vaping safety

Flavorings in vape juice, although considered safe for ingestion, have not been approved for inhalation and are not known to be safe

Additional information and recommendations will be forthcoming as our understanding of the risks associated with vaping is rapidly evolving.

One in eleven people worldwide suffer from diabetes, and 12% of the global health expenditure is attributed to its treatment. Despite spending over $300 billion on the treatment of diabetes, none offer curative therapies. Diabetes is characterized by the loss of pancreatic β-cell function, but research has shown changes in diet are beneficial in treating Type 2 Diabetes. Phytochemicals are commonly utilized in these diets, and recent studies show diets high in derived flavanols exert beneficial bioactivity for β-cells. However, given that these phytochemicals are rarely found in circulation, the direct mechanism of action is still under investigation. Gut bacteria metabolize flavanols into smaller, absorbable metabolites, which can be found in circulation. We hypothesize that these gut bacteria derived flavanol metabolites are absorbed and have direct effects on β-cell function. We test this hypothesis by feeding rats control diets or diets rich in the flavanol monomers catechin hydrate and epicatechin or grape seed extract. Here we present data regarding the in vitro effects of these absorbed gut bacteria derived flavanols on β-cell function. This study sheds further light on flavanols and their potential to promote insulin secretion and, ultimately, glucose homeostasis.

Faculty Advisor: Sinclair, Sarina (School of Medicine, Orthopaedics)

Introduction:

Osseointegration (�OI�) technology is the direct skeletal attachment of a prosthetic limb to bone using an intramedullary stem. For OI to be effective and secure, bone in-growth and remodeling around the implant must be achieved. Physicians need an effective way to measure bone remodeling in order to make informed decisions on treatments. This work describes methodology that was developed that utilizes computed tomography (CT) imaging as a tool for analyzing bone remodeling around an OI implant.

Method:

Subjects implanted with a new Percutaneous Osseointegrated Prosthesis (POP) had CTs taken of their residual femur at 6 and 52-weeks post-op. The CT images were used to segment and create three-dimensional models of the femur.

Following segmentation, models were aligned to a common world coordinate system. STLs of the aligned medullary cavity and femur volume were entered into custom Matlab code to calculate cortical and medullary morphology measurements. Morphology data from 6 and 52-week scans were compared in order to determine if bone remodeling around the POP implant could be detected.

Results:

Comparing data from post-operative visits suggests that important indicators of bone remodeling around the device could be detected. One year after implantation of the POP device the medullary parameters had minimal % differences (-1.5 and 2.2) compared to 6-weeks, validating that consistent alignment was achieved between scans from different time points. Cortical area, perimeter, and thickness around the POP implant showed positive percent changes at 12-months of 19.44%, 4.04% and 14.36% respectively. Increases in cortex morphology values indicate bone remodeling around the implant, with largest increases observed at the distal end for each parameter.

Discussion:

This pilot study utilized CT imaging as a tool for quickly and accurately analyzing bone remodeling around a new osseointegrated device. Additional work will further validate and optimize these methods for clinical use.

This study described an investigational device, limited by federal law to investigational use. No long-term data exists about its performance.

The Homeless Population and End of Life Care

December 30, 0020 12:00 AM
Trumble, Tanner; Jensen, Francine (Utah Valley University)
Faculty Advisor: Jensen, Robert (Utah Valley University, Nursing)

Background: Individuals who experience homelessness lack the necessary components needed receive end of life care (EOL). However, due to personal and structural barriers such as cost of care, lack of insurance, addiction, and many who experience mental health and intellectual disabilities, homeless individuals are unable to receive palliative or hospice care. Because homeless individuals lack the necessary components of basic living such as food, water and shelter, their quality of life is significantly lower than that of the general population, and this affects their EOL experiences.

Purpose: To explore the factors that affect the homeless population and the barriers they face when accessing health care, including their needs at the EOL, and to provide recommendations for better EOL care.

Methods: A focused literature review was performed using the databases PubMed, Google Scholar and Science Direct using the keywords homeless, end of life, and palliative care covering the years 1985 to 2018.

Findings: Homeless individuals want to experience a "good death". Unfortunately, homeless individuals who seek medical treatment feel deterred due to unfair treatment and belittlement from previous health care experiences and the social stigma surrounding homelessness. This can delay their treatment of chronic or acute conditions and lead to long-term health consequences. One effort to aid in EOL care for homeless individuals is the Social Model Hospice, which provides holistic EOL care in home like setting. Social model hospice overcomes barriers to lack of insurance, social support and a location where EOL care can be delivered for homeless individuals.

Significance: Many barriers are limiting medical care for the homeless that should be available to them at the EOL. It is evident that healthcare providers need to be more aware of the needs of this population to help improve and provide the EOL care homeless individuals deserve.

A Worldwide Phylogenetic Study of the Family Baetidae

December 30, 0020 12:00 AM
Backman, Natalia; Ogden, Heath (Utah Valley University)
Faculty Advisor: Ogden, Heath (Utah Valley University, Biology)

The Family Baetidae, is in the order Ephemeroptera, also commonly known as Mayflies. The first baetids were described around 1815 by Leach, and since there are more than 900 species have been described. The family Baetidae is an important group of mayflies because of their position on the mayfly tree of life in that they are a key to understanding evolutionary trends, such as the origin of wings and flight. Taxon sampling for this study consisted of over 100 taxa, representing ??? genera, from lineages distributed geographically worldwide, except Antarctica. Two main datasets were constructed. The genes 12s, 16s, H3, 18s, 28s and CO1 were used as part of a traditional dataset. Targeted capture sequencing was used to generate a phylogenomic dataset, consisting of over 400 loci. Trees were reconstructed from the aligned datasets, and the results were compared. The phylogenomic data resulted in a much more resolved topology.

Restoring Energy Deficits in Traumatic Brain Injuries: A Key to Effective Treatment

December 30, 0020 12:00 AM
Daines, Savannah (Utah State University)
Faculty Advisor: Adams, Brett (College of Science, Biology Department)

Traumatic brain injury (TBI) occurs when external forces cause the brain to move rapidly within the skull, resulting in an alteration of brain function. Following the initial injury, a cascade of cellular events known as the secondary injury reduces cerebral energy production and exacerbates pathological consequences. Conditions that close the mitochondrial permeability transition pore (mPTP) provide effective treatment for TBI by restoring ionic balance and coupling of mitochondrial oxidative phosphorylation to ATP production. mPTP closure can be achieved during ketosis when the body metabolizes ketone bodies over glucose as a primary fuel source. Administration of exogenous ketones achieves therapeutic levels of ketosis more quickly and more effectively than fasting or ketogenic diets. No studies to date have evaluated the effectiveness of exogenous ketones in treating TBI in humans. This project will evaluate current scientific literature regarding the role of ketones in TBIs and identify potential future approaches to using ketones as a therapy for TBI.

New Graduate Nurses Perceptions of their Preparedness to Practice after Completion of Nurse Residency Programs

December 30, 0020 12:00 AM
Perriton, Kiersten; Eppley, Sydnie; Young, Colleen (Utah Valley University)
Faculty Advisor: Jensen, Francine (Utah Valley University, Nursing)

Purpose: To determine the preparedness of new graduate nurses to practice after completion of nurse residency programs.

Background: New graduate nurses often feel anxious, concerned or ill prepared to practice as nurses on their own. New graduate nurses worry if the residency program has prepared them for their first nursing job sufficiently for them to gain enough confidence and skill to be on their own. Studies on nurse residency programs show that nurses who complete one-year nurse residency programs had remarkable increases in communicating with family, patients and team members, confidence in skills, and ability to prioritize and organize work. There is a need for continued education, such as nurse residency programs and an active interest in new graduate nurses, such as involved mentors or preceptors to help strengthen clinical reasoning and preparedness of new graduate nurses. Stress in new graduate nurses can impede patient safety and can result in the new nurse quitting the position. When new graduates have designated mentors, fit well with unit socialization, and are oriented to multiple areas, it has been identified that it can build their confidence levels and improve retention rates of new graduate nurses. Nurse residency programs need to provide high quality orientation to help them master their careers.

Significance: This research can give insight into whether the implementation of nurse residency programs helps new nurses feel ready to practice on their own. This information may help provide increased safety and quality of care to patients due to new graduate nurses feeling competent and confident to carry out the patient's health care plan. This can help healthcare companies determine if current programs are effective and what needs to be changed. New nurse graduates may gain confidence, practice with increased patient safety, and corporations may retain the new nurses they have just trained.

Baseline effects of lysophosphatidylcholine and nerve growth factor in a rat model of sciatic nerve regeneration after crush injury

December 30, 0020 12:00 AM

Faculty Advisor: Roeder, Beverly (Brigham Young University, Life Sciences)

Schwann cells play a major role in helping heal injured nerves. They help clear debris, produce neurotrophins, upregulate neurotrophin receptors, and form bands of Büngner to guide the healing nerve. But nerves do not always produce enough neurotrophins and neurotrophin receptors to repair themselves. Nerve growth factor (NGF) is an important neurotrophin for promoting nerve healing and lysophosphatidylcholine (LPC) has been shown to stimulate NGF receptors (NGFR). This study tested the administration of a single intraneural injection of LPC (1 mg/mL for single LPC injection and 10 mg/mL for multiple LPC injections) at day 0 and one (day 7), two (days 5 and 7), or three (days 5, 7, and 9) injections of NGF (160 ng/mL for single injections and 80 ng/mL for multiple injections) to determine baseline effects on crushed sciatic nerves in rats. The rats were randomly divided into four groups: control, crush, crush-NGF, and crush-LPC-NGF. The healing of the nerves was measured weekly by monitoring gait; electrophysiological parameters: compound muscle action potential (CMAP) amplitudes; and morphological parameters: total fascicle areas, myelinated fiber counts, fiber densities, fiber packing, and mean g-ratio values at weeks 3 and 6. The crush, crush-NGF, and crush-LPC-NGF groups statistically differed from the control group for all six weeks for the electrophysiological parameters but only differed from the control group at week 3 for the morphological parameters. The crush, crush-NGF, and crush LPC-NGF groups did not differ from each other over the course of the study. Single injections of LPC and NGF one week apart or multiple treatments of NGF at 5, 7 and 9 days post-injury did not alter the healing rate of the sciatic nerves during weeks 1-6 of the study. These findings are important to define the baseline effects of NGF and LPC injections, as part of a larger effort to determine the minimal dose regimen of NGF to regenerate peripheral nerves.

Faculty Advisor: Lucero, Jessica (College of Humanities and Social Sciences; Sociology, Social Work and Anthropology Department)

Refugees are recognized as having unique and complex health needs which demand attention upon arrival and throughout the resettlement process (Agrawal & Venkatesh, 2016). Refugee populations are particularly vulnerable to health disparities due to push factors influencing forced migration (Tempany, 2009). These factors include exposure to political violence, natural disasters, and other forms of anthropogenic conflict (UNHCR, 2014). Refugees may arrive in the host country with undiagnosed and untreated health issues, such as infectious diseases, mental distress due to prior traumas, undiagnosed chronic illness, and nutritional deficiencies (Deen & Bridges, 2011). Refugee populations represent high rates of mental and physical health problems compared with the host population (Kirmayer, Gomez-Carrillo, & Veissi�re, 2017). Additional dynamics compound health disparities facing refugees. These include: language barriers, unfamiliarity with a complex health care system, limited health literacy, and inadequate alignment of medical treatments with religious and cultural beliefs (Bowen, 2001; Brown, Carroll, Fogarty, & Holt, 2010). Though there is robust scholarship in the literature and analysis of prevalent health disparities and needs of refugees post-resettlement, few studies address the specific health care concerns of refugees resettled in northern Utah. This study seeks to expand previous findings related to the most salient health care issues facing the refugee community and develop community response to address health disparity. A secondary aim of the research is to determine best practices for the provision of appropriate and effective health services.

Correlation between Chronic Pain Symptoms and Brain Structure

December 30, 0020 12:00 AM
McQuinn, Sophie; Love, Tiffany (University of Utah)
Faculty Advisor: Love, Tiffany (University of Utah, Psychiatry)

Chronic pain is a major health crisis, and is considered the second major cause of disability in the world. People with chronic pain that lasts 6 months or longer often experience other symptoms as well, including depression. While the causes of chronic pain are often unknown, it has been shown that people with chronic pain exhibit brain structure differences compared to those who do not. It is important to know how chronic pain and brain structure are interconnected so that we can find a better way to treat patients. Gaining more knowledge of this connection can lead to a better understanding of the underlying causes. Brain structure goes hand in hand with neuroplasticity, which plays a key role in normal brain development. While it has been shown that chronic pain can have a significant effect on brain structure, it is unknown whether different symptoms affect different areas of the brain. The effects of chronic pain on the brain have only been looked at in a holistic sense and have not been quantified according to symptoms. Because chronic pain can have a variety of causes, this makes it difficult to determine a good method of treatment for individuals. Our aim was to determine how different symptoms of chronic pain affect the brain individually and evaluate possible overlap. The categories we tested were sensory, affective, unpleasantness, intensity, and depression. We used MRI scans from both healthy individuals and participants experiencing chronic lower back pain. The relative levels of each symptom that the participants were experiencing were determined via the McGill Pain Questionnaire and the Center for Epidemiologic Studies Depression Scale. Having a better understanding of how different symptoms of chronic pain affect the brain can aid in finding more personalized treatment for those experiencing it.

Faculty Advisor: Miles, Leslie (Brigham Young University, College of Nursing); Valentine, Julie (Brigham Young University, College of Nursing)

1 in 10 adolescents (13-18 years old) reported sexual violence in the dating environment with a prevalence rate of 14% among girls and 8% among boys (Wincentak et al., 2017). Additionally, Arliksson-Schmidt et al. (2010) found that adolescent girls with a physical disability or long-term health problem were more likely to experience sexual violence (p=.003). The current literature is limited on describing the characteristics and vulnerabilities of adolescent sexual assault patients. Researchers have found multiple negative sequelae in adolescents who have been sexually assaulted, which includes the following; major depressive disorder, suicide risk, agoraphobia, alcohol abuse & dependence, and substance abuse & dependence (Walt et al., 2014).

To better understand adolescent patients and to guide nursing care, a large (n=5,600) retrospective chart review of SAFEs documentation (2010-2018) examines adolescent descriptors (age 14-18) in a Western state in the United States. Variables include gender, race, age, relationship to suspect, online meeting, pre-existing medical conditions, pre-existing mental illness, previous history of sexual assault, number of non-anogenital injuries, number of anogenital injuries, alcohol and drug use, multiple suspects, and suspect actions (violent physical acts). Comparisons to patients over the age of 18 years will be provided.

The purpose of this podium presentation is to review research findings concerning the demographics and characteristics of adolescents seen for sexual assault forensic examinations to better inform health care professionals. Discussion will include possible medical and nursing interventions to mitigate the potential harmful effects of adolescent sexual assault.

Variations in Paint on San Juan Painted Red Ware

December 30, 0020 12:00 AM
Greaves, Aspen ; Allison, Jim (Brigham Young University)
Faculty Advisor: Allison, Jim (Family, Home, and Social Sciences; Anthropology)

Portable x-ray fluorescence (PXRF) analysis is a quantitative measure of the presence of an element. Elements from painted red ware sherds from the San Juan region were measured on painted and non-painted portions of the sherds, demonstrating the presence of elements in the paint as opposed to the paste. In particular, manganese, lead, and copper, along with a more ubiquitous iron, were found in the paint. The presences of manganese indicates the intention for the paint to be black when fired, a useful tool in identifying sherds. At Site 13 (42sa13) for example, which was burned, the sherds can appear to be Abajo red-on-orange when they may better be described as Bluff black-on-red. Lead and copper are a bit less straight-forward. Lead appears rarely, and may have no purpose, or could be an intentional sourcing choice. Another question comes from the presence of copper, which may have created a turquoise paint pre- firing. Turquoise is an important color in Pueblo color theory, and so if copper does create a turquoise paint, the presence of copper may be deliberate. Variation in paint, particularly crossed with neutron activation data, leads to a firmer understanding of decisions inherent in the ceramic creation process.

Among the staggering rates of sexual assault, little attention has been directed towards the specific risk factors involved with coercive sexual assault. The few studies that have been conducted focus solely on college campuses. Studies have found that the potential risk factors between forced sexual assault and coercive sexual assault are fundamentally different. While forced sexual assault is associated with environmental risk factors such as alcohol, coercive assault risk factors have a stronger relationship with the victim's level of depression and self-esteem. Though depression and low self-esteem can affect people for a variety of different reasons, age tends to be a reliable predictor of both of these risk factors. Depression and low self-esteem have some of the highest rates among teens and young adults. When focusing on the Military, we see depression rates higher than that of the general public, with similar patterns of teenagers and young adults (18 to 25) being the most affected. With the knowledge that depression and low self-esteem are risk factors in coercive sexual assault and knowing an age group that is more likely to be depressed and struggle with esteem, we should expect to see a relationship between age and being a victim of coercive sexual assault. In a survey consisting of veterans, age had a mild relationship with coercive rape, with younger people being more susceptible and their older counterparts holding less risk. When focusing on other distinctions of sexual crimes such as harassment, assault, and rape, age was not found to be a risk factor. Knowledge of the relationship between coercive sexual assault and age carries important implications, particularly in the form of education and support. Leaders armed with this data can inform young people of this potential risk, provide preventative strategies, and recommend therapy or support groups when necessary.
