A Machine Learning Model For Risk Stratification Of Postdiagnosis Diabetic Ketoacidosis Hospitalization In Pediatric Type 1 Diabetes: Retrospective Study, Devika Subramanian, Rona Sonabend, Ila Singh

Faculty, Staff and Students Publications

BACKGROUND: Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in pediatric type 1 diabetes (T1D), occurring in approximately 20% of patients, with an economic cost of $5.1 billion/year in the United States. Despite multiple risk factors for postdiagnosis DKA, there is still a need for explainable, clinic-ready models that accurately predict DKA hospitalization in established patients with pediatric T1D.

OBJECTIVE: We aimed to develop an interpretable machine learning model to predict the risk of postdiagnosis DKA hospitalization in children with T1D using routinely collected time-series of electronic health record (EHR) data.

METHODS: We conducted a retrospective case-control …

The Efficacy Of Common Prosthetic Joint Infection Prevention Strategies: A Systematic Review, Cameron Jennings

Theses and Graduate Projects

Thousands of total hip and knee arthroplasty patients suffer from prosthetic joint infections every year, making them a leading cause of arthroplasty failure. As the number of these procedures continues to grow, so will the healthcare and socio-economic burden of prosthetic joint infections. A comprehensive search for up-to-date literature was completed via the PubMed database, identifying eighteen retrospective and prospective cohort studies that focused on the four prosthetic joint infection prevention methods of interest. Tobacco use cessation of all forms is an efficacious prosthetic joint infection prevention strategy. The common practices of withholding intra-articular injections prior to surgery, using prophylactic …

Immunological Feedback Loops Generate Parasite Persistence Thresholds That Explain Variation In Infection Duration, Clayton E. Cressler, Daniel C.G. Metz, David A. Chang Van Oordt, Andrea L. Graham

School of Biological Sciences: Faculty Publications

Infection duration affects individual host fitness and between-host transmission. Whether an infection is cleared or becomes chronic depends on the complex interaction between host immune responses and parasite growth. Empirical and theoretical studies have suggested that there are critical thresholds of parasite dose that can determine clearance versus chronicity, driven by the ability of the parasite to manipulate host immunity. However, the mammalian immune response is characterized by strong positive and negative feedback loops that could generate duration thresholds even in the absence of direct immunomodulation. Here, we derive and analyse a simple model for the interaction between T-cell subpopulations …

2020-Current year OA Pubs

INTRODUCTION: People with HIV (PWH) have an increased risk of atherosclerotic cardiovascular disease (ASCVD) compared to non-PWH, but the reasons for this increased risk remain elusive. We investigated the change in ASCVD risk scores over 4 years to identify clinical factors associated with change in risk scores or high-risk scores.

METHODS: We conducted a preliminary study using retrospective analysis of PWH, between 40 and 75 years old, seen at the Evelyn Jordan Center with at least two routine HIV visits. We collected clinical and demographic data and calculated the ASCVD risk scores using the Pooled Cohort Equation. Exploratory analyses examined …

Analyzing Hiv/Aids Trends And Disparities In The Bronx: A Comparative Study With Nyc Boroughs, Caleb Adjei

CUNY Mexican Studies Institute

This study analyzes changes in reported HIV/AIDS cases over time in the Bronx, identifying the racial/ethnic groups and neighborhoods most affected by the disease. The Bronx consistently exhibits the highest rate of new HIV diagnoses among New York City’s boroughs, with Latino/Hispanic and Black populations being disproportionately impacted. Key neighborhoods like High Bridge-Morrisania, Crotona-Tremont, and Fordham-Bronx Park have the highest case concentrations. Despite advancements in healthcare and treatments like antiretroviral therapy, disparities persist. The findings highlight the need for targeted interventions to support the most affected communities and address the underlying social determinants contributing to the disparities in HIV/AIDS diagnoses.

A Human Stat3 Gain-Of-Function Variant Drives Local Th17 Dysregulation And Skin Inflammation In Mice, Kelsey A Toth, Erica G Schmitt, Ana Kolicheski, Zev J Greenberg, Elizabeth Levendosky, Nermina Saucier, Kelsey Trammel, Vasileios Oikonomou, Michail S Lionakis, Eynav Klechevsky, Brian S Kim, Laura G Schuettpelz, Naresha Saligrama, Megan A Cooper

2020-Current year OA Pubs

Germline gain-of-function (GOF) variants in STAT3 cause an inborn error of immunity associated with early-onset poly-autoimmunity and immune dysregulation. To study tissue-specific immune dysregulation, we used a mouse model carrying a missense variant (p.G421R) that causes human disease. We observed spontaneous and imiquimod (IMQ)-induced skin inflammation associated with cell-intrinsic local Th17 responses in STAT3 GOF mice. CD4+ T cells were sufficient to drive skin inflammation and showed increased Il22 expression in expanded clones. Certain aspects of disease, including increased epidermal thickness, also required the presence of STAT3 GOF in epithelial cells. Treatment with a JAK inhibitor improved skin disease without …

Maturation Of Germinal Center B Cells After Influenza Virus Vaccination In Humans, Katherine M Mcintire, Wooseob Kim, Sameer Kumar Malladi, Bassem M Mohammed, Julian Q Zhou, Aaron J Schmitz, Teresa Suessen, William D Middleton, Sharlene A Teefey, Rachel M Presti, Jackson S Turner, Ali H. Ellebedy, Et Al.

Germinal centers (GC) are microanatomical lymphoid structures where affinity-matured memory B cells and long-lived bone marrow plasma cells are primarily generated. It is unclear how the maturation of B cells within the GC impacts the breadth and durability of B cell responses to influenza vaccination in humans. We used fine needle aspiration of draining lymph nodes to longitudinally track antigen-specific GC B cell responses to seasonal influenza vaccination. Antigen-specific GC B cells persisted for at least 13 wk after vaccination in two out of seven individuals. Monoclonal antibodies (mAbs) derived from persisting GC B cell clones exhibit enhanced binding affinity …

The Niggling Bandersnatch: Tolkien’S Revisionist Tendencies And The Canon Of Middle-Earth, Janet Brennan Croft, David Bratman, John Rosegrant

Mythcon

C.S. Lewis famously said of Tolkien in a 1959 letter that “you might as well try to influence a bandersnatch.” He continued by noting that Tolkien had “only two reactions to criticism: either he begins the whole work over again from the beginning or else takes no notice at all.” It’s pretty obvious he had a similar reaction to his own self-criticism – to noticing a loose end, or something that didn’t fit a changed cosmological theory, or a new addition to the legendarium that required a revision to the back-story. His reaction would be to niggle away at a …

The Role Of Southern Red-Backed Voles, Myodes Gapperi, And Peromyscus Mice In The Enzootic Maintenance Of Lyme Disease Spirochetes In North Dakota, Usa, Michael W. Dougherty, Nathan M. Russart, Robert A. Gaultney, Emily Marie Gisi, Haley M. Cooper, Lindsey R. Kallis, Catherine A. Brissette, Jefferson A. Vaughan

Biology Faculty Publications

Lyme disease has expanded into the Great Plains of the USA. To investigate local enzootic transmission, small mammals were trapped in two forested tracts in northeastern North Dakota during 2012 and 2013. Peromyscus mice and southern red-backed voles, Myodes gapperi, comprised over 90% of all mammals captured. One site was dominated by Peromyscus (79% of 100 mammals captured). At the other site, M. gapperi (59% of 107 mammals captured) was more abundant than Peromyscus (36%). Immature stages of two tick species parasitized small mammals: Dermacentor variabilis and Ixodes scapularis. Larval I. scapularis ectoparasitism was significantly higher on Peromyscus (81% …

Evaluating Attitudes On Health-Seeking Behavior Among A Network Of People Who Inject Drugs, Ayako Shimada, Ashley Buchanan, Natallia Katenka, Benjamin Skov, Gabrielle Lemire, Stephen Kogut, Samuel Friedman

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

People who inject drugs (PWID) are often members of HIV/AIDS risk networks, where individuals engage in sexual and injection risk behavior. Engagement in HIV care is important for this population. Low socioeconomic status, stigmatization, and lack of access to medical care often complicate successful engagement in the HIV cascade of care for PWID. This study investigates how individual’s attitudes about how much control they have over HIV/AIDS risk in their life (i.e., locus of control and self-blame) affect health-seeking behavior in PWID participants and their community members. We applied causal inference methodology to PWID HIV risk networks ascertained from the …

Analyzing The Message Complexity, Signal Words, And Readability Of Medical Tourism Warning Messages, Alicia Mason, Sakshi Bhati

Faculty Submissions

Medical tourists are deemed to be a vulnerable patient population because they often have limited knowledge of the specialized health care treatment and services they seek. They are also frequently unfamiliar with the medical tourism physicians, providers, and facilitators with whom they interact. As a result, travel, biomedical, and procedural risks are often difficult to define and estimate. This analysis uses computer-automated technology to analyze the risk and warning messages distributed by government and private medical associations to medical tourists. Results show these messages are often complex and highly textual with little visual graphic elements. The messages frequently lack key …

Implementation Of An Evidence-Based Intervention To Improve Human Papillomavirus (Hpv) Vaccination Rates Of Children Newly Admitted To A Residential Facility., Krista Danielle Fitzgerald

Doctor of Nursing Practice Papers

Background: The Centers for Disease Control and Prevention (CDC) estimates that more than 42 million Americans are presently infected with the Human Papillomavirus (HPV). The nurse practitioner (NP), who provided primary care to children at the residential facility, reported that only 60-70% of children were consented for HPV vaccination.

Purpose: The purpose of this evidence-based intervention was to have 90% of newly admitted children consented and vaccinated for HPV. The specific aims of this project were to (1) increase staff HPV/HPV vaccine knowledge, (2) implement an updated evidence-based consent form, and (3) increase the HPV consent and vaccination rates.

Comprehensive Climate Vulnerability Assessment Of A Regional Karst Landscape For Hazard Mitigation Planning, Kara Brunot

Masters Theses & Specialist Projects

Climate change is the global phenomena affecting all sectors of society by creating conditions more conducive for the occurrence of extreme weather events. It is projected that the intensity and frequency of events will increase. Flooding, in particular, is projected to increase in frequency due to more intense precipitation events. Karst landscapes are especially vulnerable to climate change impacts because of their unique hydrology and geology. Karst flooding is most likely to occur from prolonged or intense rain events, which climate change will likely make more feasible. Areas are disproportionately affected by climate change due to population demographics and environmental …

Application Of Agent-Based Simulation And Game Theory In Evaluating Implementation Of Whole Genome Sequencing In Treating Lung Cancer, Fateme Ghalenoei

Master's Theses

Cancer, particularly lung cancer, presents significant diagnostic and economic challenges globally. Timely diagnosis and cost management play pivotal roles in treatment success. A biomarker is any measurable molecule in blood, bodily fluids, or tissues, indicating the potential presence of an abnormal bodily process, condition, or disease. Biomarker testing is a laboratory test in oncology that is used in the selection of targeted cancer treatments and to help avoid ineffective treatments. Whole Genome Sequencing (WGS), is a biomarker test which while more comprehensive, comes at a higher cost. This study proposes an agent-based simulation model within a game-theoretic framework to examine …

No. 26: Pandemic Precarities And Remittance Narratives In The Global South, Jonathan Crush, Sujata Ramachandran

Migration and Food Security (MiFOOD) Network

The COVID-19 pandemic has been referred to as a great disruptor of global migration leading to a crisis of immobility caused by public health lockdowns, closed borders, and the suspension of visa processing. Layoffs and retrenchments of migrant workers led to widespread hardship and an intensification of pre-pandemic precarity, as well as disrupted remittance channels and flows. Against this backdrop, the paper provides an overview of current debates about the relationship between COVID-19 and international migration in the context of South-South migration. We assess how pre-pandemic South-South migration flows were disrupted by the pandemic and the evidence for a crisis …

Diseases Of Cannabis Sativa And The Epidemiology And Molecular Diversity Of Neofusicoccum Parvum, Hannah V. Zima

Graduate Theses and Dissertations

Cannabis sativa has been an underutilized agricultural resource in the United States, largely due to federal regulations distinguishing marijuana from hemp. In 2018, Congress passed a Farm Bill, which defined hemp as C. sativa containing a tetrahydrocannabinol (THC) level of no more than 0.3%. As a result, commercial hemp production began in most states in 2019, including Arkansas, and was accompanied by numerous challenges like diseases and pests. The research on the epidemiology of diseases affecting C. sativa is limited, and understanding the pathogens is in its early stages in the U.S. For this study, an initial disease survey was …

Interactive Effects Between Bluetongue Virus Infection And Insecticide Exposures In Culicoides Sonorensis, Parker Mullins

Graduate Theses and Dissertations

Culicoides biting midges are common pests around the world of humans, livestock, and wildlife. In addition to nuisance blood feeding, they are also able to transmit pathogens to their hosts like bluetongue virus (BTV) and African horse sickness virus, which can be damaging in terms of both production economics and animal welfare. In order to protect humans and livestock from biting pests like Culicoides, a wide array of interventions is recommended, but chemical insecticides and repellent use are ubiquitous. For a multitude of reasons ranging from natural weathering of applied insecticides to the increase in resistance-associated mutations and behaviors in …
