Faculty, Staff and Students Publications

Debilitating abdominal pain is a common symptom affecting most patients with chronic pancreatitis (CP). There are multiple underlying mechanisms that contribute to CP-related pain, which makes successful treatment difficult. The identification of biomarkers for subtypes of pain could provide viable targets for nonopioid interventions and the development of mechanistic approaches to pain management in CP. Nineteen inflammation- and nociception-associated proteins were measured in serum collected from 358 subjects with definite CP enrolled in PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translational StuDies, a prospective observational study of pancreatitis in US adult subjects. First, serum levels of putative biomarkers were …

Faculty Research, Scholarly, and Creative Activity

To examine the factors associated with coronavirus vaccine hesitancy among students in higher education, we conducted a cross-sectional mixed-methods study between June and August 2021 among California students in higher education (n = 4444). We collected information on vaccination status, socio-demographics, and attitudes towards coronavirus vaccination. After adjusting for social demographics and social network characteristics, compared to those with household members who were vaccinated, those who had household members who were unvaccinated had 0.11 (95% CI 0.09 – 0.14) times the odds of being vaccinated. Political identification was related to vaccination status: compared to those who did not identify with …

The Method Development And Validation Of Designer Benzodiazepines In Oral Fluid Using Solid Phase Extraction And Lc-Ms/Ms, Jenna L. Monsell

Student Theses

Oral fluid is a useful biological matrix. Collection is non-invasive, quick, observable, and its correlation between oral fluid and blood drug concentration make oral fluid an important matrix to use as a roadside test. Designer benzodiazepines have become increasingly popular over the years, adversely affecting motor skills and leading to driving under the influence. Many previous studies have focused on the method development and validation of designer benzodiazepines in blood and hair but fail to validate a method to detect designer benzodiazepines in oral fluid. This study focuses on the method validation of 13 designer benzodiazepines in oral fluid using …

Using Plastinated Cadaveric Models For Anatomical Study Of Dorsalis Pedis Artery And Its Variation, Steven Bolton, Ifunanya Monube, Hooman Tabatabai-Mir

School of Podiatric Medicine - Student Research

The dorsalis pedis artery is a main artery of the dorsum of the foot. It directly arises from the anterior tibial artery and travels distally to the base of the 1st metatarsal. Its main function includes supplying oxygenated blood to the dorsal surface of the foot. A weak dorsalis pedis pulse is an indication of underlying circulation issue, such as peripheral vascular disease. Anatomical variations of the artery are not uncommon, including the total absence of the artery. Branching variations occur in approximately 10% of the population. Knowledge of these variations is critical for surgeons to prevent surgical complications

Charter For Smarter Hats: How Team Charters Dynamically Improve Trust And Emotions In Human-Agent Teams, Dan Manh Nguyen

Theses and Dissertations

Although human-agent teams have received significant attention from both practitioners and researchers in recent years, human attitudes and emotions towards agents present collaborative barriers that reduce effective teaming. Borrowing from literature on traditional human team interventions, this study examines how team charters may be leveraged to set up better trust relationships and emotional states over time, and how these key emergent states influence both objective performance scores and subjective performance ratings. Using data from 43 individuals who participated in a search-and-rescue simulation with four agent teammates, discontinuous growth modeling was used to examine differences in trust and upsetness over time …

The Effect Of Parent-Child Relationships On Healthcare Utilization Among Children With Chronic Medical Health Concerns, Karina Guerra-Guzman

Theses and Dissertations

Parents of children with chronic health complaints are more likely to utilize healthcare services for their child, and are prone to experiencing increased stress and anxiety related to their child’s compromised health status. As these parents navigate managing their child’s health and integrating parenting behaviors, they are dealt with unique stressors that are likely to impact their parenting styles, anxiety, and use of healthcare services. However, most studies that have examined HCU in the context of parent-child relationships have neglected children with chronic health concerns (CHCs). This study examined the relationship between parenting styles across parents of children with a …

All Publications

Background: Acquired estrogen receptor alpha (ER/ESR1) mutations commonly cause endocrine resistance in ER+ metastatic breast cancer (mBC). Lasofoxifene, a novel selective ER modulator, stabilizes an antagonist conformation of wild-type and ESR1-mutated ER-ligand binding domains, and has antitumor activity in ESR1-mutated xenografts.

Patients and methods: In this open-label, randomized, phase II, multicenter, ELAINE 1 study (NCT03781063), we randomized women with ESR1-mutated, ER+/human epidermal growth factor receptor 2 negative (HER2-) mBC that had progressed on an aromatase inhibitor (AI) plus a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) to oral lasofoxifene 5 mg daily or IM fulvestrant 500 mg (days 1, 15, …

International Tuberculum Sellae Meningioma Study: Preoperative Grading Scale To Predict Outcomes And Propensity-Matched Outcomes By Endonasal Versus Transcranial Approach, Michael Mcdermott

All Publications

Background and objectives: Tuberculum sellae meningiomas are resected via an expanded endonasal (EEA) or transcranial approach (TCA). Which approach provides superior outcomes is debated. The Magill-McDermott (M-M) grading scale evaluating tumor size, optic canal invasion, and arterial involvement remains to be validated for outcome prediction. The objective of this study was to validate the M-M scale for predicting visual outcome, extent of resection (EOR), and recurrence, and to use propensity matching by M-M scale to determine whether visual outcome, EOR, or recurrence differ between EEA and TCA.

Methods: Forty-site retrospective study of 947 patients undergoing tuberculum sellae meningiomas resection. Standard …

Comprehensive, Evidence-Based, Consensus Guidelines For Prescription Of Opioids For Chronic Non-Cancer Pain From The American Society Of Interventional Pain Physicians (Asipp), Radomir Kosanovic

All Publications

Background: Opioid prescribing in the United States is decreasing, however, the opioid epidemic is continuing at an uncontrollable rate. Available data show a significant number of opioid deaths, primarily associated with illicit fentanyl use. It is interesting to also note that the data show no clear correlation between opioid prescribing (either number of prescriptions or morphine milligram equivalent [MME] per capita), opioid hospitalizations, and deaths. Furthermore, the data suggest that the 2016 guidelines from the Centers for Disease Control and Prevention (CDC) have resulted in notable problems including increased hospitalizations and mental health disorders due to the lack of appropriate …

School of Podiatric Medicine Publications

Chronic inflammation and hyperglycemia in diabetic patients increase the risk of implant failure and impaired fracture healing. We previously developed and characterized a titanium (Ti) coating strategy using an imidazolium-based ionic liquid (IonL) with a fully reduced, non-oxidizable High Mobility Group Box 1 (HMGB1) isoform (Ti-IonL-HMGB1) to immunomodulate tissue healing. In this study, we used an open reduction fracture fixation (ORIF) model in non-diabetic (ND) and diabetic (D) rats to further investigate the effectiveness of this Ti-IonL-HMGB1 coating on orthopedic applications. Ninety male Lewis rats (12–15 weeks) were divided into D (n = 45) and ND (n = …

Bridging The Gap: Analyzing The Relationship Between Environmental Justice Awareness On Twitter And Socio-Environmental Factors Using Remote Sensing And Big Data, Charles Knoble, Danlin Yu

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Mounting awareness of the discriminatory distribution of environmental factors has increasingly placed environmental justice at the forefront of discussions on sustainable development, but responses to these disparities are often too little, too late. Remote sensing has emerged as a potential solution to this problem, capitalizing on the ability to capture high-resolution, spatially explicit data in near-real time. However, a conventional reliance on physical measurements and surface-level analyses risks overlooking the experiences and perceptions of affected communities. It is against this backdrop that the potential integration of remote sensing imagery and socially sensed big data such as social media data assumes …

Tumor Treating Fields: Narrative Review Of A Promising Treatment Modality For Cancer, Tugce Kutuk, Alonso La Rosa De Los Rios, Rupesh Kotecha, Minesh Mehta, Michael Chuong

All Publications

Background and objective: Tumor treating fields (TTFields) therapy have emerged as a potentially effective treatment for various malignancies by delivering low-intensity, intermediate-frequency electrical fields that disrupt many processes inside cells, resulting in the interruption of cell division in cancer cells. Additionally, TTFields therapy has been found to be synergistic with existing therapeutic approaches. In this review, we provide an introduction and background to the primary mechanisms of TTFields and discuss the emerging preclinical and clinical outcomes of this novel cancer treatment technology.

We Resist, We Heal, We Transform: Exploring Youth Of Color Journeys Towards Healing Justice In A Grassroots Organization In Urban Boston, Rhyann Leslie Robinson

Graduate Masters Theses

While many would say otherwise, the current system is not a broken one (Kaba, 2021). The colonial systems, frameworks, and theories we have in place are working exactly how they are supposed to: in favor of and in tandem with systems that seek to oppress marginalized communities. This realization calls for a shift, including shifts in research in ways that builds from below (Atallah & Dutta, 2021; Fernández, 2018; Tang-Yan, 2022). The current study aims to explicitly interrogate coloniality and colonial violence in a United States socio historical context, exploring youth of color development in conditions of adversity, looking at …

The "Messy Middle": A Framework For Analyzing Raciolinguistic Inequity, Casey Erin Anthony

Graduate Masters Theses

Existing research has demonstrated that bilingual education in the United States is highly inequitable, providing greater benefits to white English speakers than to students from minoritized backgrounds (e.g., Babino & Stewart, 2017; Palmer, 2009). Additional research has suggested that bilingual spaces also uphold whiteness and English hegemony outside of classrooms, in spaces like parent groups to administrative decisions (e.g., Gallo, 2017; Jacobsen et al., 2019). This ethnographic case study of a Spanish-English Two-Way Dual Language (TWDL) elementary school examines raciolinguistic positioning and interactions among students, teachers, and parents. Drawing on dysconscious racism (King, 1991), LangCrit (Crump, 2014), and critical consciousness …

Development Of A Methodology For The Quantification Of Reaerosolization Of A Biological Contaminate Surrogate Particle From A Military Uniform Fabric, George Cooksey, Jeremy M. Slagley, Casey W. Cooper, Douglas Lewis, Alisha Helm

Faculty Publications

In a mass casualty medical evacuation after a bioaerosol (BA) dispersal event, a decontamination (DC) method is needed that can both decontaminate and prevent biological particle (BP) re-aerosolization (RA) of contaminated clothes. However, neither the efficacy of current DC methods nor the risk of BP RA is greatly explored in the existing literature. The goals of this study were to develop a repeatable method to quantify the RA of a biological contaminant off military uniform fabric swatches and to test the efficacy of one DC protocol (high-volume, low-pressure water) using 1 µm polystyrene latex (PSL) spheres as a surrogate. A …

The Endoparasite Fauna Of Mesopredatory Mesopelagic Teleosts, Alexander U. Rayburn

All HCAS Student Capstones, Theses, and Dissertations

The ecology of the mesopelagic zone is an understudied area of the open ocean, with few diet studies even for dominant fish species. Since endoparasites are generally transmitted trophically, descriptions of the parasite communities within fishes can often provide additional insights on food web interactions. This project assesses the endoparasite faunal community of mesopredatory mesopelagic teleosts to better understand mesopelagic food webs in the South Atlantic Bight. Fishes in the Families Alepisauridae (lancetfishes), Gempylidae (snake mackerels), Bramidae (pomfrets), and Scombrolabracidae (longfin escolar) are frequent bycatch in the pelagic longline fishery targeting swordfish Xiphias gladius and thunnid tunas, yet the ecology …
