Psychology Of Athletes: Impact Of Injuries On Mental Health, Caitlin Rainey

Whittier Scholars Program

This article aims to contextualize the importance of understanding injuries in athletics and how those injuries impact mental health. With such a high prevalence of injuries in athletics, most studies analyze the physical implications on the athlete. It is vital that mental well being is studied as much as physical health throughout the injury and rehabilitation process. This study reviewed previous literature on the social impacts of team sports, psychological and social implications of injury, the impact of residual pain, and finally the process of retirement. A survey was also conducted at a small liberal arts college in Southern California …

Evaluation Of An Emergency Department Provider Information Update On The Initiation Of Suboxone With A Community Treatment Program Referral For Opioid Overdose And Opioid Use Disorder, Carmen Brewington

All Dissertations

Over 21 million people in the United States (U.S.) require substance use disorder (SUD) treatment; yet less than 4 million people receive treatment (Bressan & Kening, 2023). According to Thomas et al. (2022), opioid overdose deaths are increasing, and improving access to evidence-based treatment is critical. Hospital emergency departments (EDs) play a lifesaving in the emergency treatment of opioid overdoses; but can also serve as gateways to opioid treatment by healthcare providers for opioid addictions (Reuter et al., 2022). Mortality, after an ED visit for opioid overdose, is high (Thomas et al., 2022). Community resources are limited, thus making it …

Bcl2 Mediated Targeted Drug Delivery For The Treatment Of Kidney Fibrosis And Stomach Cancer, Humayra Afrin

Open Access Theses & Dissertations

Apoptosis, the programmed death of cells, is primarily regulated by a delicate balance between pro-apoptotic and anti-apoptotic signals. The Bcl-2 (B-cell lymphoma 2) family of proteins acts as anti-apoptotic agents, promoting cell survival. Dysregulation of these proteins is a common occurrence in conditions such as cancer and fibrosis, where overexpression of anti-apoptotic members can foster tumor cell survival and fibroblast activation. In this study, our aim was to explore the therapeutic potential of Bcl-2 inhibitors, both as a small molecule (specifically Navitoclax (Navi)), inhibitor and as Bcl-2 siRNA, for targeted treatment. Intravenous administration of Navi often leads to thrombocytopenia, necessitating …

Examining School-Age Children's Use Of Rare Words In Expository Discourse: Applications Of Computerized Analysis, Serena Jae Pedroza

Open Access Theses & Dissertations

In the school-age years, children use varied discourse styles to convey information. In addition to conversational and narrative discourse, they learn to use expository discourse to explain complex topics. Previous studies have found that compared to conversation, expository discourse samples are generally more syntactically complex (Lundine et al., 2018; Nippold et al., 2005). In addition, the vocabulary used in expository discourse may be more advanced than that in other discourse types. One way to explore vocabulary use in discourse is to measure the rarity of words within samples of discourse. The purpose of this study was to compare typically developing …

Examining The Effects Of A Week-Long Social Media Abstinence Intervention, Iweek, On General Well-Being, Mental Health, And Body Image Concerns In Latina College Students, Roberto Sagaribay

Open Access Theses & Dissertations

Latina college students, on average, spend approximately 30 hours per week on social media, highlighting the pervasive influence of social media on their lives. While social media can facilitate interpersonal relationships, its impact on mental and physical health is evident in the literature. Problematic social media use has been associated with increased rates of depression, anxiety, and decreased life satisfaction. Additionally, exposure to idealized images on social media platforms often leads to lower body satisfaction, particularly among women. Social media may also influence eating behaviors through the abundance of food advertisements and contribute to sedentary behavior, as individuals spend significant …

Selective Transfection Of A Transferrin Receptor-Expressing Cell Line With Dna-Lipid Nanoparticles And Synthesis Of Parasite-Derived Glycans As Biomarkers For Leishmaniasis, Irodiel Vinales Lozano

Open Access Theses & Dissertations

Despite notable progress in lipid nanoparticle (LNP)-mediated gene delivery, achieving selective transfection of specific cell types, such as cancer cells, remains a significant hurdle, hindering the advancement of innovative gene therapies. In this study, we engineered an LNP formulation encapsulating plasmid DNA (pDNA) encoding the monomeric Green Lantern (mGL) fluorescent reporter protein. The DT7 peptide ligand targeting human transferrin receptor 1 (hTfR1) was also conjugated to the LNP surface for targeted delivery to hTfR1-expressing cells. Optimization of LNP composition yielded favorable particle diameter, ζ-potential, yield, and pDNA encapsulation efficiency. Evaluation of transfection selectivity using a panel of two engineered cell …

Cost Saving And Resource Limited Public Health Interventions In Southeast Asia, Amanda Blackwelder

Electronic Theses and Dissertations

Background: Public health interventions are any activity with the objective of improving human health such as preventing or curing disease, reducing the severity or duration of a disease, or assisting in regaining function after a disease or injury. These interventions are known to be impactful; however, those living with the highest burden of disease such as individuals in low- and middle-income countries have limited money and resources to successfully implement these interventions. Southeast Asian countries are among some of the middle-income countries effected by the lack of affordable interventions. The aims of this study were to assess cost saving and …

Lactate Expression, Mortality, And Length Of Stay In Emergency Department Patients With Sepsis And Intubation, Heaveen Ahdi, Nadine Talia, Ray Lee, Lili Zhao, Ronny Otero, David A. Berger

Conference Presentation Abstracts

Background and Objectives: Studies demonstrate that patients in septic shock with a lactate < 2 have a mortality between 20% to 46%. Our prior work reported that in emergency department (ED) patients with a second lactate ≥2 (lac), there is a two-fold increase in 30-day mortality when compared to patients with a second lactate < 2 (alac). On secondary analysis, we found that intubated patients with a second lactate ≤2 had a longer hospital length of stay (LOS). Our objective is to further scrutinize this 30-day mortality and LOS. Methods: This is a retrospective cohort study of an eight-hospital health system using data from the electronic medical record. Inclusion criteria consisted of patients ≥18 years of age who presented to the ED from 1/1/2017 to 11/30/2022 with ≥2 lactate levels measured in the ED, were diagnosed with sepsis, and admitted to the intensive care unit (ICU) within 24 h. We excluded lactate auto-expressors, pregnant patients, transfers, and those taken for a surgical procedure within 72 h of presentation. Patients were classified based on initial and second lactate as < 2 (alac) or ≥2 (lac). Multivariable regression analysis was performed for 30-day mortality and LOS, adjusting for vitals, BMI, DNR status, and intubation timing. Results: Of the 3100 patients who met inclusion criteria, 1285 patients were intubated and categorized based on their lactate expression: alac -> alac (reference; 111/1285, 8.9%), alac -> lac (28/1285, 2.2%), lac -> alac (259/1285, 20.2%), and lac -> lac (887/1285, 69.0%). Lac -> lac had a significantly higher 30-day mortality (OR = 2.058, 95% CI = [1.353–3.154]) compared to alac -> alac. Lac -> alac had a significantly increased LOS (OR = 1.133 (95% CI = [1.003–1.280]) compared to alac -> alac. Other group comparisons for 30-day mortality and LOS were not significant. Conclusion: Intubated sepsis and septic shock patients in the lac -> lac group had a …

Diuretic Dose Ratio Is Associated With Reduced Hospital Length Of Stay In Acute Heart Failure, Sarah Galla, Yuying Xing, Lihua Qu, David A. Berger

Conference Presentation Abstracts

Background and Objectives: Congestive heart failure (CHF) is anticipated to affect eight million Americans by 2030. Treatment for CHF exacerbation is centered around IV diuretics. There are no current studies indicating an optimal initial diuretic dose in the Emergency Department (ED), and our objective is to test our hypothesis that higher diuretic dose ratio may shorten hospital length of stay (LOS). Methods: We conducted a retrospective cohort study of a large health system from 2016 to 2022. We included patients admitted from the ED with a primary diagnosis of “CHF exacerbation” with a history of CHF and prescribed diuretics. Exclusions …

Screen Positives For Potential St-Segment Elevation Myocardial Infarction: Door To Electrocardiogram By Sex And Race, Sarah Galla, Gautam Pathak, Dalia Owda, Amit Bahl, James Ziadeh, Susan Bork, Robert Swor, Karen Childers, Maya Yiadom, David A. Berger

Conference Presentation Abstracts

Background and Objectives: Detection of ST-segment elevation myocardial infarctions (STEMI) are dependent on early acquisition of an ECG. American Heart Association guidelines require performing an ECG within 10 min for patients presenting with symptoms warranting STEMI screening. A delay in ECG acquisition causes delays in diagnosis and treatment, which is associated with worsened outcomes. However, previous work has shown there is limited success at achieving a door to ECG (D2E) time of Methods: This is a retrospective chart review study in which D2E time was measured for patients positive for STEMI ECG screening criteria in a large health system with …

Capstone Projects and Master's Theses

This senior capstone research project examines the benefits of adapted physical education for students with disabilities. Through the use of literature reviews, field observations, and interviews with three elementary school teachers, the findings revealed that adaptive physical activities , such as a program called Sami’s circuit has greatly benefited students with disabilities. This kind of adapted physical activities involve the participation of many classes with a large group of students through a virtual trainer, in which teachers can easily adapt to be implemented into their individual classroom setting, and to outdoor activities as well.

The Constitutively Active Form Of A Key Cholesterol Synthesis Enzyme Is Lipid Droplet-Localized And Upregulated In Endometrial Cancer Tissues, Hudson W Coates, Tina B Nguyen, Ximing Du, Ellen M Olzomer, Rhonda Farrell, Frances L Byrne, Hongyuan Yang, Andrew J Brown

Faculty, Staff and Student Publications

Cholesterol is essential for both normal cell viability and cancer cell proliferation. Aberrant activity of squalene monooxygenase (SM, also known as squalene epoxidase), the rate-limiting enzyme of the committed cholesterol synthesis pathway, is accordingly implicated in a growing list of cancers. We previously reported that hypoxia triggers the truncation of SM to a constitutively active form, thus preserving sterol synthesis during oxygen shortfalls. Here, we show SM truncation is upregulated and correlates with the magnitude of hypoxia in endometrial cancer tissues, supporting the in vivo relevance of our earlier work. To further investigate the pathophysiological consequences of SM truncation, we …

B-cell acute lymphoblastic leukemia (B-ALL) remains a hard-to-treat disease with a poor prognosis in adults. Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is a para-caspase required for B-cell receptor (BCR)-mediated NF-κB activation. Inhibition of MALT1 in preclinical models has proven efficacious in many B-cell malignancies including chronic lymphocytic leukemia, mantle cell lymphoma and diffuse large B-cell lymphoma. We sought to examine the role of MALT1 in B-ALL and determine the biological consequences of its inhibition. Targeting MALT1 with both Z-VRPR-fmk and MI-2 efficiently kills B-ALL cells independent of the cell-of-origin (pro, pre, mature) or the presence of the Philadelphia …

Dlk-Mapk Signaling Coupled With Dna Damage Promotes Intrinsic Neurotoxicity Associated With Non-Mutated Tau, Sanming Li, Ethan R Roy, Yanyu Wang, Trent Watkins, Wei Cao

Faculty, Staff and Student Publications

Alzheimer's disease (AD) is the most prevalent form of neurodegeneration. Despite the well-established link between tau aggregation and clinical progression, the major pathways driven by this protein to intrinsically damage neurons are incompletely understood. To model AD-relevant neurodegeneration driven by tau, we overexpressed non-mutated human tau in primary mouse neurons and observed substantial axonal degeneration and cell death, a process accompanied by activated caspase 3. Mechanistically, we detected deformation of the nuclear envelope and increased DNA damage response in tau-expressing neurons. Gene profiling analysis further revealed significant alterations in the mitogen-activated protein kinase (MAPK) pathway; moreover, inhibitors of dual leucine …

Natural Language Processing Of Clinical Notes Enables Early Inborn Error Of Immunity Risk Ascertainment, Kirk Roberts, Aaron T Chin, Klaus Loewy, Lisa Pompeii, Harold Shin, Nicholas L Rider

Faculty, Staff and Student Publications

BACKGROUND: There are now approximately 450 discrete inborn errors of immunity (IEI) described; however, diagnostic rates remain suboptimal. Use of structured health record data has proven useful for patient detection but may be augmented by natural language processing (NLP). Here we present a machine learning model that can distinguish patients from controls significantly in advance of ultimate diagnosis date.

OBJECTIVE: We sought to create an NLP machine learning algorithm that could identify IEI patients early during the disease course and shorten the diagnostic odyssey.

METHODS: Our approach involved extracting a large corpus of IEI patient clinical-note text from a major …

Phosphorylation of proteins on tyrosine (Tyr) residues evolved in metazoan organisms as a mechanism of coordinating tissue growth1. Multicellular eukaryotes typically have more than 50 distinct protein Tyr kinases that catalyse the phosphorylation of thousands of Tyr residues throughout the proteome1-3. How a given Tyr kinase can phosphorylate a specific subset of proteins at unique Tyr sites is only partially understood4-7. Here we used combinatorial peptide arrays to profile the substrate sequence specificity of all human Tyr kinases. Globally, the Tyr kinases demonstrate considerable diversity in optimal patterns of residues surrounding the site of phosphorylation, revealing the functional organization of …

Bacteria Synergized With Pd-1 Blockade Enhance Positive Feedback Loop Of Cancer Cells-M1 Macrophages-T Cells In Glioma, Qi Chen, Yuyi Zheng, Xiaojie Chen, Yuan Xing, Jiajie Zhang, Xinyi Yan, Qi Zhang, Di Wu, Zhong Chen

Faculty, Staff and Student Publications

Cancer immunotherapy is an attractive strategy because it stimulates immune cells to target malignant cells by regulating the intrinsic activity of the immune system. However, due to lacking many immunologic markers, it remains difficult to treat glioma, a representative "cold" tumor. Herein, to wake the "hot" tumor immunity of glioma, Porphyromonas gingivalis (Pg) is customized with a coating to create an immunogenic tumor microenvironment and further prove the effect in combination with the immune checkpoint agent anti-PD-1, exhibiting elevated therapeutic efficacy. This is accomplished not by enhancing the delivery of PD-1 blockade to enhance the effect of immunotherapy, but by …

Leveraging Logical Definitions And Lexical Features To Detect Missing Is-A Relations In Biomedical Terminologies, Rashmie Abeysinghe, Fengbo Zheng, Jay Shi, Samden D Lhatoo, Licong Cui

Faculty, Staff and Student Publications

Biomedical terminologies play a vital role in managing biomedical data. Missing IS-A relations in a biomedical terminology could be detrimental to its downstream usages. In this paper, we investigate an approach combining logical definitions and lexical features to discover missing IS-A relations in two biomedical terminologies: SNOMED CT and the National Cancer Institute (NCI) thesaurus. The method is applied to unrelated concept-pairs within non-lattice subgraphs: graph fragments within a terminology likely to contain various inconsistencies. Our approach first compares whether the logical definition of a concept is more general than that of the other concept. Then, we check whether the …

Faculty, Staff and Student Publications

BACKGROUND: Few studies have evaluated the role of cytoreductive surgery in patients with recurrent adult granulosa cell tumors of the ovary. Despite a multitude of treatment modalities in the recurrent setting, the optimal management strategy is not known. Cytoreductive surgery offers an attractive option for disease confined to the abdomen/pelvis. However, few studies have evaluated the role of surgery compared with systemic therapy alone following the first recurrence and subsequent disease progressions.

OBJECTIVE: This study aimed to determine the impact of secondary, tertiary, and quaternary cytoreductive surgery on survival outcomes in recurrent adult granulosa cell tumors of the ovary.
