Dyrk1a And The Cell Cycle, Holly Byers, Larisa Litovchick, Md, Phd

Graduate Research Posters

The ability to halt the cell cycle is critical for cells to maintain tissue and organ size, to suppress tumors and abnormal growth, and exists as a helpful mechanism to pause the cell cycle for DNA repair. DYRK1A is (dual specificity tyrosine-(Y)-phosphorylation regulated kinase 1A) a human gene found on the long (q) arm of chromosome 21, which is known to be involved with nervous system development, cell growth and division, and neuronal differentiation. In glioblastoma cells grown in vitro (T98G cell line), there are three copies of DYRK1A, which have dosage- dependent effects on the cell, including association with …

The Effects Of A High Fat Meal On Blood Flow Regulation During Arm Exercise, Alexander Chiu, Lauren Pederson, Jeremy O. Via, Natalie J. Bohmke, Jacob Richardson, Aaron Autler, Hunter Reed, Eric Henderson, R. Lee Franco, Ryan S. Garten

Graduate Research Posters

A diet high in saturated fats results in endothelial dysfunction and can lead to atherosclerosis, a precursor to cardiovascular disease. Exercise training is a potent stimulus though to mitigate the negative effects of a high saturated fat diet; however, it is unclear how high-saturated fat meal (HSFM) consumption impacts blood flow regulation during a single exercise session.

PURPOSE: This study sought to examine the impact of a single HSFM on peripheral vascular function during an acute upper limb exercise bout.

METHODS: Ten young healthy individuals completed two sessions of progressive handgrip exercise. Subjects either consumed a HSFM (0.84 g of …

Clinical Reconciliation Of Patient Social Context And Implementation Of Preventive Care Guidelines, April Williams

Graduate Research Posters

Background

Preventive care practice guidelines are disseminated regularly through federal and scientific groups as a way of promoting best practices and evidence-based health promotion. Yet rates of their implementation are historically low and complex, with cited barriers including limits on physicians’ time, knowledge or attitudes; and external factors related to the guideline itself, the clinical environment, or patient factors. The objective of this qualitative research is to understand how primary care clinicians and staff reconcile perceived patient-level factors and implementation of preventive care guidelines.

Methods

Key informant interviews (n=23) with 14 clinicians and 9 office managers from 14 primary care …

Offering The Choice Of Self-Administered Oral Hiv Testing (Chivst) Among Long-Distance Truck Drivers In Kenya: A Trial-Based Cost-Effectiveness Analysis, Deo Mujwara, April D. Kimmel

Graduate Research Posters

Background: Long distance truck drivers (LDTD) are a high-HIV-risk population facing unique healthcare barriers due to continuous travel and irregular schedules, and may require targeted, resource-intensive strategies for HIV-test uptake. We conducted a trial-based cost-effectiveness of CHIVST among LDTD in Kenya.

Methods: Effectiveness data came from a randomized-controlled trial of CHIVST (n=150) versus provider-administered testing (n=155). Economic cost data came from the literature and reflected a societal perspective. Generalized Poisson and linear-gamma regression models estimated the effectiveness (relative-risk) and incremental costs (2017 I$), respectively, with incremental effectiveness calculated as the reciprocal of the absolute risk difference and reported as the …

Six Weeks Of Resveratrol Improves Cardiovascular Health In Patients With Copd, Rebekah Lavender, Kolton Cobb, Kendall Goldman, Paula Rodriguez-Miguelez Phd

Graduate Research Posters

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. One-third of people diagnosed with COPD die of cardiovascular (CV) complications as opposed to pulmonary. Despite these odds, there are no therapies that mitigate this important health issue. Resveratrol, a naturally occurring antioxidant, improves CV health in other populations. However, there is currently no literature on resveratrol in patients with COPD. The purpose of this pilot study was to test if six weeks of resveratrol supplementation could improve CV health in patients with COPD. METHODS: A randomized, double-blind, pilot trial was completed in 8 patients with …

Background

Colorectal cancer (CRC) is the third most common cancer diagnosed worldwide. Modifiable risk factors such as diet have been linked to the development of CRC but results of previous research have been inconsistent. We utilized the National Health and Nutrition Examination Survey (NHANES) to determine whether the consumption of dietary variables contributed to increased diagnosis of colorectal cancer.

Methods

Participants from NHANES 2015-2016 database aged 16 years or older, with available two-day dietary and CRC information were included. Study exposure included dietary consumptions (salt, cholesterol, sugar, fat, and carbohydrates); the outcome was self-reported CRC. Descriptive analysis was performed with …

Development Of An R Script For Simple Lipidomic And Metabolomic Data Analysis, Suad Alshammari, Joshua M. Morriss, Daniel Contaifer, Dayanjan S. Wijesinghe, Monther Alsultan

Graduate Research Posters

Background: Metabolomic and lipidomic studies generate vast quantities of data that are often analysed in a closed software environment with little to no access to the underlying algorithms. As a result, data processed via different software pipelines yield different results thus leading to a widespread problem of low reproducibility within these fields. To address this problem, we are developing LipidAnalyst; an R based lipidomics software pipeline. As a part of this project, we are creating a simple statistical analysis and graphing module in R to generate accurate, reproducible, high-resolution figures.

Methods: R scripts were developed under version 3.5.3 with the …

Graduate Research Posters

Background. Kineret (Anakinra) is an interleukin-1 antagonist that is under investigation for its novel clinical application treating patients that have heart failure with reduced (<50%) ejection fraction (HFrEF). A prior study from our group indicated that Anakinra may restore heart function by addressing dysregulations in HFrEF metabolic pathways. Herein, we attempt to elicit Anakinra’s effects on both metabolome and lipidome.

Methods. Lipids and metabolites that had previously been quantified by mass spectrometry (MS) from patients (n=49) who had ≥2 mg/L of high-sensitivity C-reactive protein (hs-CRP) were mTIC normalized and transformed. We conducted a stepwise Linear Discriminant Analysis (r- LDA) to test Anakinra (2 and 12 weeks) vs placebo for separation from combined baseline. Metabolic pathway analysis was performed with Fisher’s exact test algorithm for detection of over-represented and enriched analytes. Univariate analysis (one tailed t-test …

Guadecitabine, In Combination With Cyclophosphamide, Promotes Anti- Cancer Immunity In Balb/C Mice Bearing 4t1 Mouse Mammary Carcinoma, Carmen Camarena, Timothy M. Smith, Rebecca K. Martin Phd, Harry D. Bear Md

Graduate Research Posters

Background: The extremely high mortality rate of patients diagnosed with triple negative breast cancer makes it one of the deadliest forms of cancer. Due to the heterogenous nature of tumors, complete clearance is not achieved and clonal selection occurs resulting in tumor cells evading the immune system. I aim to design a therapeutic intervention that is able to elicit an effective immune response against the tumor and instill immunological memory to eradicate primary and metastatic lesions. I hypothesize that the combination of Guad and Cyp will synergize and promote anticancer immunity via increased expression of neo-tumor antigens and depletion of …

Determining the Impact of Increased Physical Activity on Improving Sleep Quality in Young Adults

Disturbed sleep, defined as any alteration to normal sleep patterns, has been linked to poor cardiovascular health and an increase in cardiovascular disease (CVD) risk. These negative sleep patterns are highly prevalent with 35% to 41% of individuals in the United States reported some form of disturbed sleep. Although high amounts of physical activity (PA) are often associated with high sleep quality, little is known about PA’s effectiveness to improve different aspects of sleep (e.g. duration vs quality) and the mechanisms to which it can improve …

Caring For Children In Child Welfare Systems: A Trauma-Informed Model Of Integrated Primary Care, Jill Mcleigh, Laura Lamminen, Heidi Roman

Integrated, Trauma-Informed Care

Children involved with the child welfare system have high rates of behavioral health concerns, chronic health conditions, and developmental disabilities. Further, as a result of the complicated relationships among the court system, child protective services, and caregivers (i.e., biological, kinship, and/or foster caregivers) and the high volume of health-, behavior-, and development-related services children in care need, the services they receive tend to be fragmented and problem driven. On top of these challenges, children involved with the child welfare system have been exposed to trauma, and often more than one form of trauma. Taken together, these factors point to the …

A Rural Mother's Guide To Breastfeeding, Haley Tillett

Undergraduate Honors Theses

Breastfeeding is considered as the gold standard of infant health (CDC, n.d.). The benefits provided to both the baby and mother by breastfeeding are unmatched when compared to formula feeding. Recent studies have shown a disparity in rates of breastfeeding, primarily in rural areas. This may be due, in part, to the fact that mothers in rural areas may not have equal access to resources and support they need to successfully breastfeed due to geographic isolation. This guide will provide an overview of breastfeeding resources in rural communities with a focus on Kittitas Valley, Washington. Resources include but are not …

Nhe1 And Tau Pathology: Tragically Tangled Together?, Caitlin Rae Wessel

Lewis Honors College Capstone Collection

Alzheimer’s Disease (AD) is an age-related neurodegenerative disease that poses a large public health challenge due to its complex, mixed pathology. One hallmark characteristic of AD is the development of toxic neurofibrillary tau tangles (NFT), which have been associated with the neurodegenerative component of AD. There is also compelling evidence that cerebrovascular disease puts individuals at a greater risk for experiencing the cognitive decline characteristic of dementias like AD. Past research has shown that individuals suffering from cerebrovascular disease and AD (not necessarily simultaneously) display an increased expression of the sodium-hydrogen antiporter-1 (NHE1), a plasma membrane protein ubiquitously expressed throughout …

Application Of High Performance Training Strategies To Enhance Occupational Readiness In Law Enforcement Cadets, Gabriel Jose Martinez

Theses and Dissertations--Kinesiology and Health Promotion

Law enforcement requires cadets to achieve a requisite level of physical fitness to prepare for occupational demands. However, there is limited research on the effectiveness of academy exercise programs to optimize physical fitness and occupational physical ability through high performance training strategies more typically utilized in elite athletic populations. Furthermore, there is a paucity of research identifying physical fitness correlates of occupational performance. Collectively, this information will provide academies and practitioners with critical information to develop evidence-based training programs. Therefore, the purposes of this study were to: Aim 1) Examine the effectiveness of integrating autoregulatory progressive resistance exercise (APRE) and …
