A previous study demonstrated noninferior efficacy of 4-month rifapentine/moxifloxacin regimen for tuberculosis (TB) treatment compared with the standard regimen. We analyzed pregnancy outcomes of women who became pregnant during the study. Among 740 women, 97 (13.1%) became pregnant. Of 102 pregnancies (in 97 participants), 30 (29.4%) participants were exposed to study drugs. Fetal loss was reported for 3/13 (23.1%) in the control regimen, 1/9 (11.1%) in the rifapentine/moxifloxacin regimen, and 1/8 (12.5%) in the rifapentine regimen. Among 21 live births in exposed pregnancies (7 in each arm), 1 infant with a congenital anomaly was reported in a participant on the …


Meme Wars As Socially Situated Learning: Learning In Online Communities Of Hate, Conspiracy, And Insurgency, Kevin M. Clark Jan 2025

Meme Wars As Socially Situated Learning: Learning In Online Communities Of Hate, Conspiracy, And Insurgency, Kevin M. Clark

Midwest Social Sciences Journal

Learning is important in a pluralistic democracy, to enable citizens to make informed decisions. However, with the rise of the internet and social media, we need more than ever to understand how learning is shaped by social context and intertwined with issues of identity and belonging. One theoretical framework that addresses these social aspects of learning comes from the work of Jean Lave and Etienne Wenger on socially situated learning in communities of practice. This article focuses on what many would consider to be the darker side of learning—the rise of hate, disinformation/conspiracy, and insurgency in online communities. Specifically, it …

Utilization Of Model-Based Approaches To Maximize Efficacy Of Antibiotics For The Treatment Of Mycobacterium Abscessus Pulmonary Infection, Hyunseo Park Jan 2025

Utilization Of Model-Based Approaches To Maximize Efficacy Of Antibiotics For The Treatment Of Mycobacterium Abscessus Pulmonary Infection, Hyunseo Park

Theses and Dissertations (ETD)

Prevalence and incidence of Mycobacterium abscessus (Mab) pulmonary infections have increased and been recognized as a major cause of mortality, particularly in certain patient populations, such as cystic fibrosis (CF) patients. Due to the intrinsic multidrug resistance mechanisms and biofilm (BF) formation properties of Mab, effective treatment remains challenging, as these factors significantly diminish the antibacterial activity of drugs. Current treatment guidelines recommend prolonged therapy, generally more than 12 months with a multidrug combination of at least four agents. However, no optimal combination, regimen, or treatment duration has been universally established for Mab pulmonary infections (Mab-PI). Therefore, the selective and …

Comparison Of Compositional Characteristics Of Protein Extracted From Spent Hemp Seed Cakes By One-Step Defatting With Organic Solvents Followed By Isoelectric Solubilization Precipitation Using Strong And Weak Acids, Miah Nicole Gathman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Hemp seed cakes (HSC) are the byproduct of pressing hemp seeds for oil and are a significant agricultural waste product, with hundreds of tons produced annually. These nutrient-rich cakes have potential for sustainable applications in animal feed and food products. However, they could offer even greater value to the food industry through further extraction of the lipids and separation of the proteins they contain. Protein is a key nutritional component and companies are seeking cost-effective, time-efficient processes to concentrate protein from underutilized resources like HSC. Hexane (HEX) is a common solvent used in one-step defatting processes but may cause issue …

Publications

Background: Digital technologies are reshaping health care, making digital health literacy (DHL) a critical competency for navigating online health information. Although widely conceived and measured as a unidimensional measure of DHL, the literature increasingly supports a multidimensional framing of the eHealth Literacy Scale (eHEALS). Studies propose alternative factor structures that can better inform population-level interventions, but these studies have not accounted for the ordinal nature of eHEALS response data. Objective: This study aimed to identify and validate an alternate multidimensional structure of eHEALS accounting for its ordinal response scale. Methods: Data were drawn from the 2022 GetCheckedOnline community survey of …

Breaking Ground On Self-Efficacy: A Qualitative Exploration Of Intimate Partner Violence Survivors’ Experiences With Therapeutic Horticulture, Rachel Marie Reeves Jan 2025

Breaking Ground On Self-Efficacy: A Qualitative Exploration Of Intimate Partner Violence Survivors’ Experiences With Therapeutic Horticulture, Rachel Marie Reeves

Theses and Dissertations--Sociology

This dissertation explores how participation in a Therapeutic Horticulture program may support the self-efficacy of survivors of Intimate Partner Violence. Through a thematic analysis of interviews with 45 women living at a domestic violence shelter in Lexington, Kentucky, this study investigates whether and how gardening activities contributed to participants’ belief in their abilities to shape outcomes in their lives.

Findings are organized around Bandura’s four sources of self-efficacy: enactive mastery experiences, vicarious experience, verbal persuasion, and physiological/affective states. These insights contribute to feminist criminology and trauma-informed care literature by illuminating the transformative potential of nature-assisted healing programs.


The Influence Of The Covid-19 Pandemic On Student Engagement At A Historically Black University, John C. Travis Jan 2025

The Influence Of The Covid-19 Pandemic On Student Engagement At A Historically Black University, John C. Travis

Theses and Dissertations

This study examined student engagement across three NSSE administrations at an HBCU—pre-COVID (2018), during COVID (2019), and post-COVID (2022). Engagement was analyzed across four themes: Academic Challenge, Learning with Peers, Experiences with Faculty, and Campus Environment. Results showed that Learning with Peers declined significantly over time, with the largest drop between 2018 and 2022, reflecting pandemic-related disruptions to peer interaction. No significant year effects emerged for the other themes. Two-way MANOVAs indicated that gender, first-generation status, and major did not significantly predict engagement, nor did they interact with year. In contrast, classification emerged as the most consistent predictor, with upper-division …

Browse all Theses and Dissertations

Antibody production is an essential component of the immune response against pathogens. The immunoglobulin heavy chain (IgH) gene codes for the heavy chain of antibodies. The IgH constant regions Cμ, Cδ, Cγ1-4, Cα1-2, and Cε encode the five major classes of antibodies, i.e., IgM, IgD, IgG1-4, IgA1-2, and IgE, respectively. The transcription of the IgH gene and class switch from IgM to other isotypes is regulated by two 3’ IgH regulatory regions (3’IgHRRs), each of which is a cluster of three enhancer regions (hs3, hs1.2 and hs4). The genetic variations in the hs1.2 enhancer have been identified; a ~53 bp …

Causal Discovery On The Effect Of Antipsychotic Drugs On Delirium Patients In The Icu Using Large Observational Ehr Dataset, Riddhiman Adib, Md. Osman Gani, Sheikh Iqbal Ahamed, Mohammad Adibuzzaman

Computer Science Faculty Research and Publications

Delirium occurs in about 80% of cases in the Intensive Care Unit (ICU) and is associated with an extended hospital stay, increased mortality, and other complications. Delirium lacks biomarker-based diagnosis and is frequently treated with antipsychotic drugs (APD), despite numerous studies debating its efficacy. Since randomized controlled trials (RCT) are expensive and time-consuming, we approach the research question of estimating the efficacy and safety outcomes of APD in treating delirium through retrospective cohort analysis. We employed the Causal inference framework to explore the underlying causal model for Delirium patient cohort. We focus on building a structural causal model for delirium …


The Supreme Court During Covid-19: Keeping Its Head When Those About It Were Losing Theirs, Timothy C. Macdonnell Jan 2025

The Supreme Court During Covid-19: Keeping Its Head When Those About It Were Losing Theirs, Timothy C. Macdonnell

South Dakota Law Review

Alexander Hamilton's Federalist No. 78 suggests that one of the reasons for a life-tenured judiciary whose pay cannot be altered is because "judges may be an essential safeguard against the effects of occasional ill humours in the society." Our Nation's history is replete with instances of ill humor leading to violations of constitutional rights. Wars, epidemics, natural disasters, civil unrest, and economic crises all demand governments to act and act swiftly. But courts, and particularly the United States Supreme Court, are necessary to check governments when they go too far in contending with an emergency. Historically the country's courts have …


“We Just Go With The Flow”: Healthcare Providers As Secondary Impacted Subjects In Informal Refugee Healthcare Provision In Indonesia, Realisa D. Masardi, Elan Lazuardi Jan 2025

“We Just Go With The Flow”: Healthcare Providers As Secondary Impacted Subjects In Informal Refugee Healthcare Provision In Indonesia, Realisa D. Masardi, Elan Lazuardi

Masyarakat: Jurnal Sosiologi

With prolonged transit times, refugees’ right to health in Indonesia has become an urgent issue. This article asks how healthcare providers are positioned within Indonesia’s ambiguous refugee health provision regime. Drawing on qualitative fieldwork, this study moves beyond a legalistic analysis of refugee health rights by foregrounding the precarious positions of healthcare providers themselves. We examine Presidential Regulation 125/2016 as well as state and non-state actors’ views on what are often described as structural barriers in improving refugees’ rights. We argue that conditions of informality, which both arise from and perpetuate institutional ambiguity, systematically undermine refugees’ right to health while …

Elucidation Of The Post-Transcriptional Regulation And Role In Iron Homeostasis Of The Outer Membrane Vesicle Protein Ynce In Salmonella, Mira J. Schmidt Jan 2025

Elucidation Of The Post-Transcriptional Regulation And Role In Iron Homeostasis Of The Outer Membrane Vesicle Protein Ynce In Salmonella, Mira J. Schmidt

Honors Undergraduate Theses

Iron is an essential element for most bacteria as it is a crucial cofactor for enzymes involved in fundamental reactions such as DNA synthesis. Despite being the fourth most abundant element on Earth, bacteria face challenges acquiring iron under aerobic conditions due to the poor solubility of its oxidized form (Fe³⁺). To overcome this, bacteria have developed various strategies of iron acquisition, such as the production of siderophores. Siderophores are small molecules that scavenge free Fe³⁺ in iron-deprived environments. Iron acquisition is tightly regulated due to its capability of promoting hydrogen peroxide formation via the Fenton reaction. In Salmonella Typhimurium, …


Genomic Epidemiology Of Staphylococcus Aureus Sequence-Type 72, Sachitaa Senthilkumar Jan 2025

Genomic Epidemiology Of Staphylococcus Aureus Sequence-Type 72, Sachitaa Senthilkumar

Honors Undergraduate Theses

Staphylococcus aureus (S. aureus, SA) is a gram-positive bacterial colonizer and pathogen commonly carried on the skin and in the anterior nares of humans. SA colonization may lead to a variety of non-invasive (e.g., skin and soft tissue infections, SSTIs) and invasive (e.g., bacteremia and osteomyelitis) infections. The SA population is comprised of multiple lineages that can be delineated through multi-locus sequence typing (MLST), which compares nucleotide sequences within seven housekeeping genes. Strains belonging to an MLST share a common evolutionary history and phenotypic characteristics like antibiotic resistance or virulence. As a result, the epidemiology of lineages can be …


Development Of A Proposed Selective Medium For The Isolation And Differentiation Of P. Sordellii, Dimyana Bottros Jan 2025

Development Of A Proposed Selective Medium For The Isolation And Differentiation Of P. Sordellii, Dimyana Bottros

Honors Undergraduate Theses

Clostridium, a genus of anaerobic, spore-forming bacteria, includes clinically and ecologically significant species like Clostridium difficile and Paeniclostridium sordellii. C. difficile causes antibiotic-associated colitis, while P. sordellii is linked to fatal infections and spontaneous abortions. Recent studies found both species in marine sediments, suggesting their role in environmental and wildlife health disturbances, including the 2013 mass mortality of over 300 manatees in the Indian River Lagoon. However, isolating and differentiating P. sordellii is challenging due to the lack of selective media optimized for its growth. This thesis proposes a novel selective medium tailored to P. sordellii’s physiological …
