Outcome Analysis Of Tranexamic Acid In Thromboembolic Complications And Coagulation Factors, Hunter A. Mccorkle

University Honors Theses

Background: Tranexamic acid (TXA) is an antifibrinolytic used for controlling hemorrhaging in patients. It’s regular application in trauma centers could be vital in reducing all-cause mortality for hemorrhaging secondary to traumatic injury but there are still concerns about possible side effects and populations at greater risk of complications. The possible use of predictive measures such as thrombelastography (TEG) and conventional coagulation testing (CCT) in detecting early markers of TXA risks are still unconfirmed, and unfortunately there is a time restriction of 3 hours for TXA to be effective in reducing all-cause mortality.

Objective: Our objective is to observe outcomes of …

The Experience Of Family Therapists Providing An In-Person Group Intervention, Responding To The Covid-19 Pandemic, And Attempting To Continue With A Comparable Intervention In A Virtual Setting, Miranda R. Gab

University Honors Theses

Group interventions are widely used in mental health and educational settings. Studies have shown that these groups can be conducted in either in-person or virtual settings with success, though there is limited research on the delivery of synchronous, online group interventions, particularly an in-person group intervention that abruptly transitioned to telehealth delivery due to the coronavirus. This observational research aims to tell the story of how two family therapists, who served as co-facilitators for an in-person parenting intervention, transitioned to deliver the same content virtually due to the restrictions of the COVID-19 pandemic. Drawing upon previous and present research in …

The Utility Of Multiplex Closeness Centrality For Predicting Item Difficulty Parameters In Anomia Tests, Khanh L. Nguyen

University Honors Theses

Background: Confrontation naming tests for the assessment of aphasia are perhaps the most commonly used tests in aphasiology. Recently, such tests have been modeled using item response theory approaches. Despite their advantages, item response theory models require large sample sizes for parameter estimation that are often unrealistic when working with clinical populations. As an alternative approach, Fergadiotis, Kellough & Hula (2015) explored automatic item calibration by regressing item difficulty parameters on word length, age of acquisition (AOA), and lexical frequency as quantified by the Log10CD index. Despite the high predictive utility that they achieved, the model’s performance was far from …

In August 2005, Hurricane Katrina brought upon the city of New Orleans, LA one of the costliest natural disasters in U.S. history. This paper looks at how hospitals were prepared before Katrina, responded to, and grappled with the aftermath of this natural disaster. In the aftermath of Katrina, careful investigation of the healthcare system along with its hospitals, physicians, patients, and residents allow us to take innovative measures and provide guidance to create recommendations to better monitor and care for individuals in the future. Frameworks of resilience theories, studies, and recommendations display how and why disaster planning is essential. The …

Exploring Perceptions Of Healthcare Quality In Oregon Male Prisons: Interviews With Individuals Recently Released From Long-Term Imprisonment, Rén Rosz

University Honors Theses

The healthcare that people who are imprisoned receive is inadequate and does not meet the requirements owed to them by the Eighth Amendment. The Bureau of Justice Statistics has repeatedly surveyed inmates about the health care that they receive (Bureau of Justice Statistics [BJS], n.d.). One of the most recent iterations, in 2004, showed that there were large gaps in the health care that prisoners received: not being able to see a healthcare provider after an injury, necessary medications being discontinued, and lab tests being restricted (Wilper, et al, 2009). The surveys were implemented to highlight policies needing correction and …

Differential Effects Of Buprenorphine/Naloxone Vs. Methadone On Quality Of Life Over Time: A Subset Of The Bravo Study (Buprenorphine To Improve Hiv Care Engagement And Outcomes: A Randomized Trial), Ali Mirzazadeh Javaheri

University Honors Theses

Health-related Quality of Life (QoL) is generally poorer in individuals with opioid use disorder (OUD) in comparison with those suffering from other chronic diseases. Little is known about the difference each buprenorphine/naloxone (BUP/NX) or methadone maintenance therapy (MMT) may make in the QoL for the HIV-infected people with OUD who are new to HIV care. The objective of this study is to evaluate the difference in the impact that BUP/NX and MMT treatment delivery models make on the QoL of the HIV-infected participants with OUD in Vietnam.

This study was a subset of the BRAVO study, buprenorphine to improve HIV …

Iron-Deficiency Anaemia (Ida): Socio-Cultural Misconceptions Intersect The Health Of Vulnerable Populations In Developing Countries, Samantha G. Alarcon Basurto

University Honors Theses

Iron is a mineral that the human body uses to make hemoglobin, a protein that red blood cells need to carry oxygen from the lungs to all parts of the body. The lack of adequate iron in the blood is known as iron deficiency, which if experienced in greater proportions, can lead to anaemia. Iron-deficiency anaemia is generally understood as a nutritional deficiency that can be treated by diets of food rich in iron content or the ingestion of iron supplements; yet lack of information, restricted access to bioavailable iron-rich foods, minimal awareness of anaemia’s detrimental effects on children’s cognitive …

Sex Differences In Prevalence And Psychophysiological Profiles Of Adhd, Mckenzie Figuracion

University Honors Theses

Background: Considerable research has been dedicated to understanding the etiology of Attention-Deficit/Hyperactivity Disorder (ADHD), but the focus has been on a homogeneous subset of the population, and multiple groups go underserved when it comes to support. Previous findings suggest differences in ADHD diagnosis and referral rates based on sex, but it is less clear whether neurophysiological sex differences exist. The current study examines the effect of expert consensus diagnostic practices on rates of diagnosis in males and females, and evaluates sex differences in potential neurophysiological markers of ADHD.

Methods: 860 children and adolescents (Males=519; ADHD=516) were recruited for a longitudinal …

A Public Health Recommendation Countering The Online Anti-Vaccination Movement, Grace M. Neumann

University Honors Theses

The anti-vaccination movement had posed a threat to the health of communities, since the inception of the smallpox inoculation practice. As the anti-vaxx movement continues to grow in strength and reach, public health officials must be prepared to combat the flow of misinformation, with sound scientific data in a way that connects with individuals from all communities. Online platforms such as blogs and social media, allow newfound access to vaccine opinions and information, posing an even greater risk of vaccine misinformation being spread to the public. Different communities hold different reasons for vaccine hesitancy and avoidance. An effective public health …

University Honors Theses

The purpose of this research was to describe how telepractice can be used as a speech-language pathology service delivery model with a school-age child who stutters. Specifically, the research questions were: 1) Can a school-age client who stutters increase their use of stuttering modification strategies to manage their stuttering through telepractice? 2) Can a school-age client who stutters increase acceptance of stuttering through telepractice treatment?

Reviewing The Potential Link Between Grain-Free Diets And Dilated Cardiomyopathy In Canines, Larissa J. Webster

University Honors Theses

Grain-free diets for dogs are becoming increasingly popular, but concerns are emerging following the FDA's recent investigation that there might be a link between grain-free diets and Dilated Cardiomyopathy (DCM) in dogs with no known genetic predisposition. Contrary to the majority of the public thought, dogs do nutritionally require grains, and there is rarely a medical reason to switch to a grain-free diet. Not all cases of DCM are linked to diet, and many dogs who are fed grain-free diets do not develop the disease; the extent of this issue therefore is not entirely known. This review aims to explore …

Sudden Cardiac Death In Young Adults With Long-Chain 3-Hydroxyacyl Coa Dehydrogenase Deficiency (Lchadd), Ajesh Saini

University Honors Theses

Long-chain 3-Hydroxyacyl CoA Dehydrogenase Deficiency (LCHADD) is an autosomal recessive defect in fatty acid oxidation that presents with hypoketotic hypoglycemia and/or hypertrophic cardiomyopathy in infancy, and recurrent rhabdomyolysis in adolescence, however, sudden cardiac death has not been a previously reported complication of LCHADD. We have conducted a case review study comparing young adult LCHADD patients who have experienced sudden cardiac arrest events (n=5) to similar patients who have not (n=5) for the purpose of evaluating associated cardiac risk factors. We reviewed medical records from ECG tests, hospitalization reports, acylcarnitine, and complete metabolic panels, clinic notes, and autopsy reports. Retrospective chart …

Inhibition Of Cancer Causing Genes Through The Delivery Of Omomyc In Anti-Myc Therapy: A Systematic Review, Angie Mcgraw

University Honors Theses

A systematic review of the available studies on the interference of OmoMyc with Myc's function in cancerous cells is presented. Myc is a transcription factor that regulates cellular processes such as apoptosis, proliferation, and differentiation. However, Myc is often overexpressed in a variety of cancers, resulting in abnormal growth of cancer cells. Although the inhibition of Myc has been highly desired, it remained a challenge due to its undruggable characteristics. Attempts to inhibit Myc have involved the usage of small-molecules, but these attempts have failed, causing adverse effects and incomplete inhibition of Myc. Despite promising preclinical studies of OmoMyc, it …

Centering Children In Co-Parenting, Kristen L. Wiidanen

University Honors Theses

Comprehensive systems theory identifies several associated risk factors and consequences of separation but, research suggests that legal divorce itself has few direct effects on children. While there is diversity in children’s responses to separation, generally associated risk factors are behavioral disruptions, emotional upheaval, anger, resentment, anxiety, guilt and depression. Parents abilities to cope with their divorce are critical to the child’s adjustment and, if parents are able to control their feelings toward their ex-spouse, cooperate in parenting, negotiate differences, and settle their quarrels in privacy, their children will show fewer social and emotional problems. It is expected that the curriculum …

Frequency Of Limited English Proficient (Lep) Patient Visits And Language Resources: An Assessment Of Rural Oregon's Health Centers And Working With Lep Communities, Gabriel I. Lehrburger

University Honors Theses

Persons with limited English proficiency (LEP) can face barriers when seeking health care. Rural communities often have reduced access to some health resources. However, little is known about how rural communities meet the language needs of their LEP populations. A cross-sectional survey and interview were designed and sent to managerial staff in rural health centers around the state of Oregon. During the months of January – March 2020, survey and interview data were collected to assess the relationship between frequency of LEP patient visits and available language resources in rural Oregon.

Meta-Analysis Of Tobacco Control Policies For Reducing Tobacco Consumption, Arya Kevin Naghdi

University Honors Theses

The harmful effects of tobacco consumption and smoking have been well documented, and the literature is conclusive on their negative effects. However, there is still a great deal of discussion to be had on which policies and strategies can be employed to decrease smoking rates. Tobacco control policies used in the past included tobacco taxes, smoke free zones, anti-smoking media, sale to minors bans, and advertising restrictions on tobacco companies. Yet, it is still unclear which policies are most effective and least effective when it comes to reducing smoking rates. A meta-analysis of 11 articles analyzing the effects of each …

Exploring An Instrumented Balance Assessment In Athletes With Acute Mild Traumatic Brain Injury Compared To Healthy Athletes And Non-Athletes, Bryana Popa

University Honors Theses

Balance deficits are common following mild Traumatic Brain Injury (mTBI) and can persist beyond the standard recovery period. Advances in wearable technologies, such as inertial measurement units (IMUs), have increased utilization of instrumented balance assessments. There are limited studies providing normative ranges for the Balance Error Scoring System (mBESS) to characterize abnormalities in people with mTBI. This thesis provides balance ranges for athletes with acute mTBI and normative control populations completing the mBESS. Testing occurred at the university athletic facility or the Balance Disorders Laboratory at Oregon Health & Science University (OHSU) and the Veterans Affairs Portland Health Care System …

Examining Integration And Sense Of Belonging Among Undergraduate Students Participating In Stem Support Programs, Mackenzie J. Gray

University Honors Theses

National calls have been made to strengthen our nation’s Science, Technology, Engineering, and Mathematics (STEM) workforce by improving student preparation and increasing retention rates. A sense of belonging in STEM fields is thought to be key for persistence in STEM, but many students face academic, social, and financial barriers that can impede this sense of belonging. These barriers can be more pronounced for students underrepresented in STEM. In response, many federal and non-governmental agencies have invested in the future STEM workforce by funding STEM support programs. Such programs aim to support student persistence by providing academic, social, and financial resources …
