Modeling An Infection Outbreak With Quarantine: The Sibkr Model, Mikenna Dew, Amanda Langosch, Theadora Baker-Wallerstein

Rose-Hulman Undergraduate Mathematics Journal

Influenza is a respiratory infection that places a substantial burden in the world population each year. In this project, we study and interpret a data set from a flu outbreak in a British boarding school in 1978 with mathematical modeling. First, we propose a generalization of the SIR model based on the quarantine measure in place and establish the long-time behavior of the model. By analyzing the model mathematically, we determine the analytic formulas of the basic reproduction number, the long-time limit of solutions, and the maximum number of infection population. Moreover, we estimate the parameters of the model based …

The Association Between Acculturation & C-Reactive Protein In U.S. Immigrants: A Cross-Sectional Study, Jessica Kilinski Bs, Rosol Mikail Bs, Kelly M. Reavis Phd, Mph, Deborah Karasek Phd, Mph

OHSU-PSU School of Public Health Annual Conference

Purpose: Immigrants undergo acculturation as they assimilate to a different culture, potentially leading to immense stress. Our objective was to examine the association between acculturation and C-reactive protein (CRP), a marker of stress-induced inflammation. We hypothesized that U.S. foreign-born adults 20 years and older with higher degrees of acculturation would have higher CRP levels compared to those with lower acculturation.

Method: We used 2017-2018 National Health and Nutrition Examination Survey (NHANES) data from 1526 participants to conduct a cross-sectional analysis. We measured acculturation as language spoken at home (categorized as low, moderate, and high) and examined its association with CRP …

Broken Promises: Prolonged Diminished Quality-Of-Life Among Liberian Ebola Survivors Half A Decade After The 2014-16 West African Outbreak, Jessi Hanson-Defusco, Decontee Davis, Meghana Bommareddy, Zainab Olaniyan

Journal of Social, Behavioral, and Health Sciences

The 2014–2016 Ebola outbreak left thousands of Liberian survivors with severely diminished quality of life. Applying a social determinants framework, this mixed method study investigates to what extent Ebola virus disease (EVD) survivors suffer long-haul psychosocial stress, diminished quality-of-life factors, and the impact of EVD-related service provisions on their ongoing healing. We present the results of a quantitative analysis survey of data collected from 19 Liberian EVD survivors in 2022 using snowball sampling. Additionally, a qualitative analysis of survivor statements helps triangulate key statistical findings and inform causal mechanisms. Survivors report experiencing 5.25 of a total of 7 ongoing stressors …

Faculty Publications

Background

Sleep problems are associated with abnormal cardiovascular biomarkers and an increased risk of cardiovascular diseases (CVDs). However, studies investigating associations between sleep problems and CVD biomarkers have reported conflicting findings. This study examined the associations between sleep problems and CVD biomarkers in the United States.

Methods

Data were from the National Health and Nutrition Examination Survey (NHANES) (2007–2018) and analyses were restricted to adults ≥ 20 years (n = 23,749). CVD biomarkers [C-reactive Protein (CRP), low-density lipoproteins, high-density lipoproteins (HDL), triglycerides, insulin, glycosylated hemoglobin (HbA1c), and fasting blood glucose] were categorized as abnormal or normal using standardized cut-off …

Chronic pain is a common problem, with more than one-fifth of adult Americans reporting pain daily or on most days. It adversely affects the quality of life and imposes substantial personal and economic costs. Efforts to treat chronic pain using opioids had a central role in precipitating the opioid crisis. Despite an estimated heritability of 25-50%, the genetic architecture of chronic pain is not well-characterized, in part because studies have largely been limited to samples of European ancestry. To help address this knowledge gap, we conducted a cross-ancestry meta-analysis of pain intensity in 598,339 participants in the Million Veteran Program, …

Decoding Implant-Related Sickness: Unraveling The Complexities Of Breast Implant Illness, Madison M. Stewart

Senior Theses

This thesis investigates the phenomenon of breast implant illness (BII), examining its potential correlation with individual factors such as obesity and poor lifestyle habits. BII, characterized by nonspecific symptoms, is often self-diagnosed by patients influenced by social media and internet sources, leading to requests for implant removal. Conducting a comprehensive meta-analysis, the study scrutinizes existing literature to evaluate the association between BII, obesity, and lifestyle choices. Employing inclusion criteria, peer-reviewed publications are analyzed through systematic review methodology to offer insights into the interplay between BII and adiposity, exploring inflammatory mechanisms and patient behaviors like exercise and smoking. The research aims …

BACKGROUND: In 2020, 2.8 million people required substance use disorder (SUD) treatment in nonmetropolitan or 'rural' areas in the U.S. Among this population, only 10% received SUD treatment from a specialty facility, and 1 in 500 received medication for opioid use disorder (MOUD). We explored the context surrounding barriers to SUD treatment in the rural United States.

METHODS: We conducted semi-structured, in-depth interviews from 2018 to 2019 to assess barriers to SUD treatment among people who use drugs (PWUD) across seven rural U.S. study sites. Using the social-ecological model (SEM), we examined individual, interpersonal, organizational, community, and policy factors contributing …

Faculty, Staff and Student Publications

Large-scale, evidence-based interventions face challenges to program fidelity of implementation. We developed implementation strategies to support teachers implementing an evidence-based HIV prevention program in schools, Focus on Youth in The Caribbean (FOYC) and Caribbean Informed Parents and Children Together (CImPACT) in The Bahamas. We examined the effects of these implementation strategies on teachers' implementation in the subsequent year after the initial implementation during the COVID-19 pandemic. Data were collected from 79 Grade 6 teachers in 24 government elementary schools. Teachers completed training workshops and a pre-implementation questionnaire to record their characteristics and perceptions that might affect their program fidelity. School …

A Latter-Day Disease: Mormons And Cholera In The Nineteenth Century, Alexandra L. Wein

Student Publications

Nineteenth-century America saw the emergence of two seemingly parallel entities - the epidemic disease of cholera and the Church of Jesus Christ of Latter-day Saints, better known as the Mormon faith. To understand the intersection of Mormons and cholera, one must look within the interdisciplinary framework of Civil War-era history, religion, and epidemiology. Cholera epidemics in 1832 and 1849 coincided with the mass Mormon migration west, causing great suffering and death for Mormons traveling by land and sea. While their westward exodus exposed them to cholera, their religious teachings also contributed to why they contracted the disease. The Word of …

Examining Childhood Trauma And Substance Use Problems Among Justice-Involved Adolescents In Florida, Skye C. Bristol

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation was to assess the relationship between childhood trauma and substance use problems as latent constructs among justice-involved adolescents (JIA). Additionally, racial differences and spatial analyses were examined. Previous research underscores the limitations of conceptualizing childhood trauma solely through Adverse Childhood Experiences (ACEs). This justified integrating child welfare involvement, or out-of-home placement, as an additional indicator to develop a comprehensive scope of childhood trauma among JIA. Furthermore, current literature established that childhood trauma is a key predictor of substance misuse among JIA. However, the lack of a standardized measure of substance misuse across juvenile justice systems …

Exploring The Associations Between Drug Resistant Mutations, Low-Level Viremia, And Virological Failure In Persons With Hiv In Florida, Adriana Campos

USF Tampa Graduate Theses and Dissertations

Virologic suppression is an essential part to a successful regimen for Persons with HIV (PWH) and the 95-95-95 initiative. Yet, PWH experiencing episodes of low-level viremia (LLV) may be more prone to experience virological failure (VF). Currently, studies debate the clinical relevance of LLV and its effect on virological outcomes, but none have explored its interconnectedness with drug resistant mutations (DRM) and antiretroviral treatment (ART) adherence – all integral elements in predicting virological outcomes.

The goal of the proposed study was to contribute to the knowledge gap regarding the interconnectivity of drug resistant mutations, low-level viremia, adherence, and virological failure …

Community-Centered Early Warning For Outbreaks In Humanitarian Emergencies: Evaluating Community-Based Surveillance For Priority Communicable Diseases Among Internally Displaced Populations In Iraq, Caitlin M. Wolfe

USF Tampa Graduate Theses and Dissertations

Background: Community based surveillance (CBS) is the organized and rapid collection of information from health events identified in the community and includes the systematic detection and reporting of events of public health significance. While used globally to enhance the detection of priority diseases, CBS has not been routinely deployed in Iraq, where a once-robust health system has been devastated by decades of war, international sanctions, and large-scale population displacement. During infectious disease outbreaks, it is imperative to quickly detect and isolate suspect cases, investigate confirmed cases, and trace and monitor the contacts of confirmed cases. The COVID-19 pandemic underscored the …

Lstm-Based Recurrent Neural Network Predicts Influenza-Like-Illness In Variable Climate Zones, Alfred Amendolara, Christopher Gowans, Joshua Barton, David Sant, Andrew Payne

Annual Research Symposium

Purpose: Influenza virus is responsible for a recurrent, yearly epidemic in most temperate regions of the world. For the 2021-2022 season the CDC reports 5000 deaths and 100,000 hospitalizations, a significant number despite the confounding presence of SARS-CoV-2. The mechanisms behind seasonal variance in flu burden are not well understood. Based on a previously validated model, this study seeks to expand understanding of the impact of variable climate regions on seasonal flu trends. To that end, three climate regions have been selected. Each region represents a different ecological region and provides different weather patterns showing how the climate variables impact …
