Physical And Psychosocial Factors Related To Firefighter Musculoskeletal Disorders, Jennifer Ellen Tinsley Kubala

Theses and Dissertations--Rehabilitation Sciences

Career firefighters must perform physically and psychologically challenging duties in unpredictable and dangerous conditions. Previous investigations have found that firefighters suffer nearly 4 times the recorded musculoskeletal disorders (MSD) and workplace injuries compared to private and public sector workers, and take approximately 1.5 days longer to return to normal work. Thus, the burden of firefighter MSD experiences has been a growing area of exploration. The few investigations that have concurrently examined physical and psychosocial consequences experienced by firefighters have found a positive relationship between increased occupational stress reports and MSD experiences. However, these investigations, as well as those that individually …

The Role Of Social Determinants Of Health On Patient Recovery After Critical Illness, Lindsey E. Fresenko

Theses and Dissertations--Rehabilitation Sciences

Patients who survive critical illness have a prolonged recovery which impacts their quality of life and outcomes. The sudden life changes from being critically ill may create or exacerbate social factors or needs also known as social determinants of health. Patients’ SDOH are defined as the environments in which we live, work and play that impact health outcomes. Patients’ SDOH impact their life in early recovery from changes in previous roles to their need for increased financial, physical and emotional support. During this early recovery, patients are often recommended to participate in rehabilitation to improve their physical function. Although, accessing …

Background. Delirium is an acute clinical syndrome that is characterized by features of disrupted arousal, attention, cognition, sleep, and perception. Delirium is a well-documented phenomenon in critical care settings in both adult and pediatric populations, particularly among patients with length of stay greater than or equal to 48 hours. Delirium has multiple adverse effects, including increased mortality rate, prolonged duration of mechanical ventilation, higher reintubation rates, prolonged intensive care unit (ICU) admission, prolonged hospital admission, short- and long-term cognitive impairment, and posttraumatic stress disorder. There are currently no accepted guidelines or FDA approved medications to treat ICU delirium in the …

The Psychosocial Aspects Of Rest, Morgan Findley

Theses and Dissertations--Kinesiology and Health Promotion

Past research in sport sciences has focused primarily on “rest” from a physical perspective, while giving limited focus to the psychosocial perspective (Eccles & Riley, 2014; Eccles et al., 2022). One major development on psychosocial rest emerged with the pioneering model introduced by Eccles and Kazmier (2019); however, further research is needed to test this proposed model with other sport/performance populations. Therefore, this study aimed to assess the model's generalizability and investigate the perceived frequency of psychosocial rest by athletes throughout their season. To accomplish this, 67 female university athletes completed an online survey comprised of questions representative of the …

Increasing Physical Activity: Parenting Style, Parental Perceptions, And Teacher Use And Self-Efficacy, Kendra Hansen

Theses and Dissertations--Kinesiology and Health Promotion

This dissertation consists of three papers aimed at varied ways to increase physical activity for youth. The first paper reviews research on hyper-parenting and its effects on physical activity. The systematic literature review revealed that little is known about hyper-parenting effects on physical activity, but limited evidence suggests a negative relationship between the two variables.

The second manuscript examines parents’ perceptions of physical activity and its effect on their children’s academics. Results showed some minor differences between ethnic groups and those whose children are more active. Although parents tended to agree that physical activity was important, most did not seem …

Effects Of Neonatal Estradiol Treatment On Regulating Sexual Differentiation Of Daily Rhythms Underlying Diet-Induced Obesity In Female Mice, Samuel Nwadialo

Theses and Dissertations--Biology

Sex differences of the brain and behavior often require the combination of organizational and activational effects of sex hormones. The activational effects of estrogens in adult female mice protect daily eating and activity rhythms from disruption by high-fat diet feeding and inhibit diet-induced obesity. However, male mice have disrupted eating rhythms when fed high-fat diet and this causes obesity. Treatment of adult male mice with estradiol does not protect rhythms from disruption by high-fat diet, as it does in females. In this study, we sought to determine whether the organizational effects of estradiol masculinize the daily eating and activity rhythms …

The Effect Of Estrogen And A Mitochondrial Uncoupling Prodrug On Traumatic Brain Injury-Induced Dysfunction In Mice., Olivia J. Kalimon

Theses and Dissertations--Neuroscience

A large percent of both clinical and pre-clinical traumatic brain injury (TBI) studies report better outcomes females after severe injury compared to males. Mitochondrial dysfunction is a well-characterized driver of secondary injury and an attractive neurotherapeutic target; though, there is limited research available on mitochondrial dysfunction in females. However, a few studies have shown total mitochondria from the cortex of females appear protected from TBI-induced bioenergetic dysfunction. These results were replicated in these studies so further characterization was performed. Additionally, protein expression of some oxidative phosphorylation (OXPHOS) complexes were elevated in the uninjured cortex of females relative to uninjured males, …

A Praxis Towards Social Change Based On Foucault's Conceptualization Of Experience As Relational, Lila Maureen Wakeman

Theses and Dissertations--Philosophy

This project develops a praxis towards social change based on the works of Michel Foucault. It first establishes Foucault’s philosophical assumptions, methods, and political goal of countering “objectivizing” modern Western social forces. It then draws on sources from the three major phases of Foucault’s career to trace his development of a general conceptualization of experience as relational, or as non-exhaustively co-constituted by and through three indispensable kinds of social forces: knowledge, power, and ethics. It then evaluates implications of Foucauldian experience for efforts towards social change to conceptualize a general Foucauldian praxis towards social change. The praxis aims to affect …

Investigating A New Drug Target In Alzheimer’S Disease: Nox2, Tiffany Adams

Theses and Dissertations--Pharmacy

Introduction: Alzheimer’s disease (AD) is a neurodegenerative disease with neuropathological changes in the blood-brain barrier that offers possible therapeutic targets. Oxidative stress is one driving factor for AD. NADPH oxidase 2 (NOX2) in the capillary endothelium produces reactive oxygen species, leading to oxidative stress-mediated blood-brain barrier dysfunction. We hypothesized that using a specific NOX2 inhibitor, PhoxI2, has the potential to reduce reactive oxygen species and repair amyloid-β (Aβ)-driven blood-brain barrier leakage in an AD mouse model.

Methods: For this study, 5xFAD (Familiar Alzheimer Disease) mice were treated with vehicle or PhoxI2, a NOX2 inhibitor. Techniques utilized were Enzyme-Linked Immunosorbent Assay …

There are many different dysphagia screening tools with no consensus. This study aimed to compare the two most frequently used dysphagia screenings, a patient-reported outcome measure (PROM), the EAT-10, and bolus-driven swallow screening, the Yale Swallow Protocol, to determine if one tool is superior in aspiration prediction on a videofluoroscopic swallow study (VFSS). This study also aimed to discover the best cutoff score on the EAT-10 for aspiration prediction. A total of 66 participants were recruited after physician …

The Relationship Between Sleep, Physical Activity, And Musculoskeletal Injury, In Us And Saudi College Students, Abdulaziz Hasan Alameer

Theses and Dissertations--Rehabilitation Sciences

According to the National Sleep Foundation, individuals should sleep 7-9 hours every night. Recently, insufficient or poor sleep has been linked to diabetes, cardiovascular illness, stroke, obesity, and Alzheimer's disease. Insufficient sleep for college students can negatively impact academic performance and mental health. In addition, especially for collegiate athletes, there is evidence that insufficient sleep is associated with an increased risk of musculoskeletal injury. However, it is uncertain if the link between sleep and injury varies between populations, types of individuals (athletes vs non-athletes), sports or types of exercise, or training volume. Despite the health risks of inadequate sleep, up …

Using Inertial Measurement Units (Imus) To Assess Fatigue-Related Changes In Running: Applications In Training Load Management, Reiley Thomas Bergin

Theses and Dissertations--Rehabilitation Sciences

The inertial measurement unit (IMU) is the most researched wearable technology in running. Yet, few studies have validated IMU-derived measures against accepted laboratory standards, such as three-dimensional (3D) motion capture and force plates. IMUs have the potential to provide information that can guide training load management decisions; however, no study has explored their capability to assess fatigue-related changes in running across consecutive days of training. Therefore, the purpose of this project was to evaluate the validity and reliability of IMU-derived measures and assess their capability for detecting fatigue-related changes in running in the days following an intensified training bout. The …

Abl1/2 And Ddr1 Cooperate To Stabilize Braf/Craf To Drive Erk1/2 Reactivation And Promote Mek Inhibitor Resistance In Nras-Mutant Melanomas, Anastasia Lyon

Theses and Dissertations--Pharmacology and Nutritional Sciences

This study addresses the escalating incidence of NRAS-mutant melanomas, a type of skin cancer lacking FDA-approved targeted therapies. Despite ongoing research targeting the RAF/MEK/ERK pathway, existing drugs fail to enhance progression-free survival due to acquired resistance. This project identifies a novel role for ABL1/2 and DDR1 kinases in driving drug resistance and proliferation of NRAS-mutant melanoma cells. ABL1/2 and DDR1 cooperate to promote RAF homodimerization and protein stability in order to reactivate MEK/ERK signaling to drive MEK1/2 inhibitor (MEKi) resistance and promote survival of resistant cells. By targeting ABL1/2 and DDR1 with nilotinib, a FDA-approved anti-leukemic inhibitor, we …

The Function Of The Insulin Receptor In Liver Subcell Types And Its Dichotomous Role In Hepatic Dysfunction, Wang-Hsin Lee

Theses and Dissertations--Pharmacology and Nutritional Sciences

Insulin resistance and metabolic dysfunction-associated steatotic liver disease (MASLD) have become significant health issues worldwide. Increased prevalence of hepatic insulin resistance and MASLD worsens the threat of its progressive complications, such as liver fibrosis, which can lead to cirrhosis and death if left untreated. Treatments for MASLD-induced liver fibrosis are mainly insulin sensitizers. However, activating insulin signaling leads to a higher death rate in end-stage liver fibrosis. This dissertation discusses the emerging insights into hepatic insulin resistance and potential treatment targets in the heme degradation pathway for reversal. We also investigated the mechanisms that the insulin receptor (INSR) regulates in …

Exenatide As Chronopharmacotherapy For T2dm Associated Complications: Targeting Nondipping Blood Pressure And Sleep Insufficiency, Aaron Chacon

Theses and Dissertations--Pharmacology and Nutritional Sciences

Although largely impacted by age, race and ethnicity, and socioeconomic factors, Type 2 Diabetes Mellitus (T2DM) is primarily driven by obesity, currently affecting ~30 million in the U.S and ~463 million globally. T2DM carries numerous complications, including high prevalence of hypertension and nondipping blood pressure (BP), sleep insufficiency and fragmentation. Nondipping BP is an inadequate drop in BP (≤ 10%) during sleeping hours compared with waking hours. Lending to this, sleep disturbance acts as both precursor and consequence of metabolic dysregulation, greatly impacting circadian rhythmicity. To model these conditions, we utilized diabetic (db/db) mice. These mice carry a point mutation …

Theses and Dissertations--Pharmacology and Nutritional Sciences

Heart failure (HF) following myocardial infarction (MI) remains a significant global health concern, with the initial ischemic injury often leading to microvascular damage and infarct expansion, exacerbating the overall cardiac impairment. Despite extensive research, there are currently no effective therapies to limit myocardial damage post-MI, resulting in a substantial number of patients progressing to HF. Stem cell therapy has emerged as a promising approach to modulate cardiac injury and promote healing. However, clinical trials have shown only modest success, underscoring the need for improved strategies to enhance efficacy. Additionally, the lack of significant ventricular regeneration highlights the necessity of targeting …

The Delineation Of Platelet Pathology In Cardiometabolic Disease, Chi Peng

Theses and Dissertations--Pharmacology and Nutritional Sciences

Obesity is a multifactorial disease with many comorbidities leading to multiorgan dysfunction. Current studies point towards dysregulation of platelet signaling as a driver for increased risk of cardiovascular disease and stroke. The exact mechanisms remain elusive due to the complex interplay of factors involved, warranting the need to further understand how platelets are affected. Our preliminary data evaluating changes in platelet and coagulation parameters from bariatric patients showed that obesity did not affect platelet count or clotting time as demonstrated in INR values. However, female patients had increased bleeding events before surgery that were decreased after surgery. Due to limitations …
