Background There remains limited information concerning US transfeminine persons preferences across varying PrEP options. We examined PrEP option willingness, preferences, and associated factors among a US nationwide sample of transfeminine persons. Methods Sexually active transfeminine persons age 15 + were recruited online between June 2022-October 2023 through social media advertisements. Transfeminine persons not diagnosed with HIV were asked about willingness to initiate, and ranked preference, of three PrEP options- daily oral (DO), on-demand, and long-acting injectable (LA-PrEP). Log-binomial models were used to examine PrEP modality willingness and associated sociodemographic and behavioral characteristics. Results Among 2657 transfeminine persons not currently using …

Advancing Pandemic Response: Integrated Strategies For Testing, Prediction, And Bias Mitigation, Tianshu Gu

Theses and Dissertations (ETD)

The COVID-19 pandemic, along with prior outbreaks such as SARS and Ebola, has revealed critical gaps in global pandemic preparedness, emphasizing the need for integrated approaches to infectious disease management. This dissertation addresses three key areas of pandemic response: developing scalable screening strategies, constructing reliable predictive models, and mitigating demographic biases in artificial intelligence (AI) models used for healthcare decision-making.

The first study introduces a global screening strategy designed to optimize resource use and increase testing capacity, particularly in low- and middle-income countries (LMICs) where resources are limited. This study leverages pooled testing methods, where multiple samples are combined into …

The Impact Of Hyperglycemia On Post-Reperfusion Outcomes In Patients With Hyperacute Ischemic Stroke, Nicole Schumacher

Theses and Dissertations (ETD)

Stroke is a major contributor to disability in the United States, with ischemic stroke accounting for approximately 87% of all cases. The use of approved reperfusion therapies, including intravenous thrombolysis with tissue plasminogen activator (tPA) and mechanical thrombectomy, has significantly improved functional outcomes for ischemic stroke patients. However, hyperglycemia at the time of hospital arrival is associated with worse outcomes, including increased infarct growth, higher rates of disability, and elevated mortality. Despite this, current stroke guidelines neither exclude hyperglycemic patients from receiving reperfusion therapy nor recommend glucose management during the hyperacute phase of care. While recent studies suggest that mild …

Ccr7 Regulated Mechanisms That Limit The Adaptive Immune Response, Jaisel Amilcar Cervantes

Open Access Theses & Dissertations

C-C chemokine receptor 7 (CCR7) is critical in guiding T cell migration within the thymus and peripheral lymphoid tissues, shaping the adaptive immune response by promoting central tolerance and regulating immune homeostasis. Although its role in lymphocyte trafficking is well established, the molecular mechanisms by which CCR7 influences thymocyte development and T cell receptor (TCR) repertoire formation remain less understood. This study examines how CCR7 deficiency impacts thymic selection, TCR diversity, and the signaling events that shape repertoire restriction. Using a homozygously deleted CCR7 murine model, we found that the absence of CCR7 results in a less restricted TCR repertoire …

Pterygoid Implant-Retained Bridge Following Multiple Failed Alveolar Implants In Posterior Maxilla, Kouder Dakhallah Dds, Anish Gupta Dds, Joey Wilmot, Brian Giammalva Dds

The Journal of the Michigan Dental Association

The replacement of multiple teeth with dental implants in the posterior maxilla is challenging due to factors including low density bone and sinus morphology. When considering restoration of this region, prosthetic design will dictate implant placement. Additionally, planning must consider spacing between adjacent implants, spacing between implants and adjacent teeth, and irregular alveolar ridge morphology. These key measurements translate to the final prosthesis design and will affect cleanability and future oral hygiene maintenance. These characteristics subsequently affect overall longevity of the implants and prosthesis.

In the following case, multiple closely-placed implants presenting with poor cleanability consequently failed, requiring removal and …

Medical Professionals' Perceptions Of Healthcare Artificial Intelligence, Falon M. Costigan

Electronic Theses and Dissertations

This study examined whether medical professionals across different levels of expertise show differences in their perceptions of healthcare artificial intelligence (AI). Specifically, the researcher hypothesized that participants with more expertise and experience would have greater negative perceptions associated with AI in healthcare compared to participants with a lower expertise level. Participants completed a questionnaire evaluating their perceptions of healthcare AI across four components: long-term negative consequences of AI, need for AI safeguards, positive perceptions of AI, and AI control. Participants also completed demographic questions evaluating participants' age, sex, ethnicity, years working in a healthcare setting, medical …

Estimating Proximity To Failure Using Repetitions In Reserve In Adults Treated For Cancer, Kylah Elizabeth Jackson

Theses and Dissertations

BACKGROUND: There is a consensus from governing bodies that more evidence is needed in understanding how to properly prescribe, monitor and progress resistance training (RT) in oncology populations. Repetitions in reserve (RIR) has been demonstrated as a quick/easy tool to monitor proximity to failure and interventions using RIR have shown promise in improving muscle strength and mass in older adults and apparently healthy populations. However, the validity of RIR in RT in oncology has yet to be examined. Therefore, the purpose of this study was to assess the accuracy of RIR predications in individuals treated for cancer in a pragmatic …

However, only a couple of studies have been conducted on the association between risk of tumours and use of electronic devices using low frequency (LF) EMF. Methods: We studied the use of common household electrical appliances and suspected risk of tumours in a multi-hospital-based case-control study. In total, 316 patients were included in the final analysis. Results: The study results showed a below unity risk for …

The Contribution Of Individual Movements To The Learning Of A Movement Sequence, Hannah K. Ammons

Senior Theses

This thesis explores how the overall learning of a motor sequence through repeated practice is impacted by the individual movement’s components. Changes seen in the response time, peak velocity, and the hand path distance were examined whilst considering the Fitts’s ID and inertial demands of the individual movements. During data collection, twenty-four right-handed participants completed a series of repeated and random reaching movements that varied in direction and distance in a 3D virtual environment. When considering only the repeated sequences, the results indicated significant improvement in both the hand path distance and response time across all target combos, specifically Target …

The Benefits Of Blood Flow Restriction Training Combined With Low-Load Resistance Training In Arthritis Treatment: A Scoping Review, Maya L. Butcher, Dr. Christine Pellegrini, Kailyn Horn

Senior Theses

Background: Arthritis is a condition affecting millions worldwide, with osteoarthritis (OA) and rheumatoid arthritis (RA) being the most common forms. Resistance training is a widely accepted intervention to strengthen muscles and support joint function, however, high-load resistance training may exacerbate joint pain. Blood Flow Restriction (BFR) training, which involves applying controlled vascular occlusion during low-intensity resistance exercises, has gained attention as a potential alternative to promote muscle growth and strength with minimal joint stress. Objective: This scoping review aims to explore the benefits of BFR techniques in conjunction with low-intensity resistance training for the treatment of arthritis. Methods …

An Evaluation Of Exercise-Related Self-Efficacy Metrics Following A Resistance Training Program In Individuals Treated For Cancer, Kayla S. Adler

Senior Theses

As the number of cancer survivors grows, managing treatment side effects and promoting healthy behaviors like physical activity is crucial. Low exercise self-efficacy, an individual's belief in their capability to perform exercise, is a significant barrier to physical activity adherence. This study assessed if an 8-week supervised resistance training program could improve self-efficacy for exercise (SEE) and outcome expectations of exercise (OEE) in individuals treated for cancer. Participants (n=25) attended twice-weekly, one-hour sessions. SEE and OEE scales were administered pre- and post-intervention. Results indicated a significant increase in SEE scores (mean difference = 8.96 ± 19.87, p = 0.041), demonstrating …

Examining Racial Disparities In Cancer Incidence And Mortality Across South Carolina Regions, William Stokes, Swann Arp Adams, Kara M Montgomery

Senior Theses

Purpose: To provide updated cancer mortality-to-incidence ratio (MIR) data across South Carolina (SC).

Methods: State and national incidence and mortality data were collected from the South Carolina Central Cancer Registry (SCCCR) and the National Cancer Institute’s Surveillance Epidemiology and End Results Program (SEER). MIRs (mortality rate/incidence rate) were calculated for all cancer sites, cervical, colon, female breast, lung and bronchus, oral cancers, and prostate cancers from the years 2016-2021, excluding 2020.

Results: Major racial disparities in MIR were found in SC, with the largest discrepancies seen in cervical, colon, and prostate cancers. Of note, each SC region had white cervical …

The Effect Of Grape Seed Extract Against The Formation Of S.Aureus Biofilms In A Clinical Setting, Srestha Samaddar

Senior Theses

The rise of antibiotic-resistant bacterial infections, particularly those caused by Staphylococcus aureus, poses a serious threat to public health and clinical care. A major contributor to the persistence of these infections is the formation of bacterial biofilms, structured communities that protect S. aureus from antibiotics and immune responses, especially on surgical sites and medical devices. As conventional treatments become less effective, interest in alternative, natural antimicrobial agents has increased, due to public dissatisfaction with conventional medicine and a growing trust in complementary and alternative medicine. Grape seed extract (GSE), a polyphenol-rich byproduct of winemaking, has emerged as a promising candidate …

Estimation Of Therapeutic Threshold For Tuberculosis Using Adapted Nominal Group Technique And Clinical Vignettes In Clinical And Community Settings In Southern Africa, Alfred Kipyegon Keter, Alastair Van Heerden, Tom Decroo, Tom Boyles, Shannon Bosman, Thandanani Madonsela, Lindani Innocent Msimango, Lenika Naiken, Carlos Kiyan, Mashaete Kamele

Population Health, East Africa

Background: When confronted with diagnostic uncertainty and a decision on whether to start treatment or not, clinicians consider the potential harm and benefit of offering versus withholding treatment. Treatment can be offered if the probability of tuberculosis (TB) in the patient is above the “therapeutic threshold” (ThT): the probability of disease at which the expected utility of treating and not treating is the same. We estimated ThT for TB in clinical and community settings in Southern Africa using two methods: an adapted nominal group technique (aNGT), and decisions made based on clinical vignettes (CVs).

Methods: We enrolled health …

Emergence Of Transferable Daptomycin Resistance In Gram-Positive Bacteria, Tessa Marciniak, Lukas Kirchner, Silver A. Wolf, Birgit Walther, Thorsten Bischler, Justin Nyasinga, R Gunturu, Torsten Semmler, Tom Gräfenhan, Andrew Whitelaw

Pathology, East Africa

Daptomycin (DAP) is a last-resort antibiotic to treat infections by multiresistant Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci. DAP resistance and clinical treatment failure has been associated with adaptive chromosomal mutations, but so far not with transmissible resistance traits. Here we report for the first time an acquired DAP-R determinant (named drc) that we detected in a livestock-associated Mammaliicoccus sciuri isolate. drc consists of a two-gene operon (drcAB) that is controlled by an adjacent two-component system (drcRS). The DrcAB proteins, which mediate DAP inactivation, are similar to BceAB-like antimicrobial peptide transporters of Gram-positives, but are distinct from …

Time Tracking And Comparison Of Genetic Counseling Tasks In Inpatient And Outpatient Settings, Alexandra Osborne, Emily Magness Bland, Callie Diamonstein, Kristen Fishler

Faculty, Staff and Students Publications

Genetic counselors (GCs) practice in critical care settings. Some GCs have full-time inpatient roles, while most GCs who see inpatients do so as needed or on a rotating schedule in addition to seeing patients in an outpatient setting. Few studies have tracked and compared the amount of time it takes GCs to perform tasks in the inpatient and outpatient settings. Genetic counselors were invited to participate in this study via the National Society of Genetic Counselors research listserv. Participants completed an online survey asking how their role is structured and what types of support are available to them while seeing …

We are in the era of millimetre-scale electron microscopy volumes collected at nanometre resolution1,2. Dense reconstruction of cellular compartments in these electron microscopy volumes has been enabled by recent advances in machine learning3–6. Automated segmentation methods produce exceptionally accurate reconstructions of cells, but post hoc proofreading is still required to generate large connectomes that are free of merge and split errors. The elaborate 3D meshes of neurons in these volumes contain detailed morphological information at multiple scales, from the diameter, shape and branching patterns of axons and dendrites, down to the fine-scale …

Intestinal Epithelial Serotonin As A Novel Target For Treating Disorders Of Gut-Brain Interaction And Mood, Lin Y Hung, Nuno D Alves, Andrew Del Colle, Ardesheer Talati, Sarah A Najjar, Virginie Bouchard, Virginie Gillet, Yan Tong, Zixing Huang, Kirsteen N Browning, Jialiang Hua, Ying Liu, James O Woodruff, Daniel Juarez, Melissa Medina, Jonathan Posner, Raquel Tonello, Nazli Yalcinkaya, Narek Israelyan, Roey Ringel, Letao Yang, Kam W Leong, Mu Yang, Ji Ying Sze, Tor Savidge, Jay Gingrich, Robert J Shulman, Michael D Gershon, Annie Ouellet, Larissa Takser, Mark S Ansorge, Kara Gross Margolis

Faculty, Staff and Students Publications

Background & aims: Mood disorders and disorders of gut-brain interaction (DGBI) are highly prevalent, commonly comorbid, and lack fully effective therapies. Although selective serotonin reuptake inhibitors (SSRIs) are first-line pharmacological treatments for these disorders, they may impart adverse effects, including anxiety, anhedonia, dysmotility, and, in children exposed in utero, an increased risk of cognitive, mood, and gastrointestinal disorders. SSRIs act systemically to block the serotonin reuptake transporter and enhance serotonergic signaling in the brain, intestinal epithelium, and enteric neurons. Yet, the compartments that mediate the therapeutic and adverse effects of SSRIs are unknown, as is whether gestational SSRI exposure directly …

Combined Systemic Immunotherapy And Intrathecal Dexamethasone In Febrile Infection Related Epilepsy Syndrome, Kristen S Fisher, Alexander Ankar, Jon Cokley, Eyal Muscal, James J Riviello, Yi-Chen Lai

Faculty, Staff and Students Publications

Febrile infection related epilepsy syndrome (FIRES) is a rare presentation of refractory status epilepticus with immune dysregulation as a potential pathologic mechanism. Despite promising results from second-line immunomodulators, approximately 30% remain refractory to treatment. We describe two children with FIRES who were unable to wean from anesthetic infusions with immunomodulatory treatment and subsequently received concurrent intrathecal dexamethasone and anakinra/tocilizumab as escalation of therapy. Following the initiation of this combined regimen, anesthetic infusions were decreased while maintaining seizure freedom. These cases demonstrate proof of principle that a multi-modal approach may be beneficial and should be considered in the treatment of FIRES.

Hypertriglyceridemia (HTG), particularly in combined hyperlipidemia, increases risk for atherosclerotic cardiovascular disease, but the underlying mechanisms remain incompletely understood. We sought to determine contributions of circulating monocytes to atherosclerosis associated with HTG in combined hyperlipidemia, created by transgenic expression of human apoCIII in Ldlr−/− mice (Ldlr−/−ApoCIIItg) fed Western high-fat diet (WD). Tissue culture with THP-1 and primary human monocytes was used to examine effects of triglyceride (TG)-rich lipoproteins on monocytes. Ldlr−/−ApoCIIItg mice were also treated with apoCIII antisense oligonucleotide (ASO) and examined for foamy monocytes and atherosclerosis. Compared to Ldlr−/− mice, Ldlr−/−ApoCIIItg mice fed …
