Reaction Toward Potential Resurgent Multiple Risks: Understanding Risk Information Seeking And Behavior In The Post-Pandemic Era, Shudan Huang Oct 2024

Reaction Toward Potential Resurgent Multiple Risks: Understanding Risk Information Seeking And Behavior In The Post-Pandemic Era, Shudan Huang

Theses and Dissertations

This study applies the Risk Information Seeking and Processing (RISP) model to understand how individuals seek and process information related to overlapping pandemics, including COVID-19, flu, monkeypox, and polio. These overlapping health crises have created a complex media environment, contributing to pandemic fatigue, information overload, and varied preventive behaviors. The research explores how pandemic fatigue influences informational behaviors—such as information seeking, processing, and avoidance—and how these behaviors, in turn, predict preventive behavioral intentions.

Using an online survey of 443 participants, structural equation modeling was employed to test the hypotheses. Results indicate that information insufficiency positively predicts both information seeking and …


Using Machine Learning And Deep Learning Algorithms To Improve Low Birthweight Prediction, Yang Ren Oct 2024

Using Machine Learning And Deep Learning Algorithms To Improve Low Birthweight Prediction, Yang Ren

Theses and Dissertations

Low birthweight (LBW) is a major public health issue resulting in increased neonatal mortality and long-term health complications. Traditional LBW analysis methods, focusing on incidence rates and risk factors through statistical models, often struggle with complex unseen data, and thus, their effectiveness is limited in early prevention of LBW, requiring more advanced LBW prediction models. Therefore, this dissertation delves into this important research area by proposing and examining novel machine learning (ML) and deep learning (DL) algorithms, aiming to predict LBW more accurately during the early stage of pregnancy. This dissertation consists of three studies, strategically designed to build upon …


Systemic Inflammation And Neurocognitive Deficits In School-Age Children With Sickle Cell Disease., Elizabeth A. Gillooly Oct 2024

Systemic Inflammation And Neurocognitive Deficits In School-Age Children With Sickle Cell Disease., Elizabeth A. Gillooly

Theses and Dissertations

Sickle cell disease (SCD) causes inflammation that contributes to poor clinical outcomes, including cerebrovascular disease (CVD). CVD can take several forms in SCD, including neurocognitive deficits without visible cerebral infarction. The role of chronic inflammation in cognitive development in SCD has received little attention to-date. We aimed to study novel markers of systemic inflammation: neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and the systemic inflammation index (SII) to describe developmental trends and relationships to cognitive outcomes in SCD at early elementary school-age. Sixty-one children with SCD and no history of stroke were identified who completed an early elementary school age cognitive …

Theses and Dissertations

Colitis is an inflammatory bowel disease characterized by dysregulation of the immune system that results in chronic inflammation and dysbiosis. Previously we showed that a naturally sourced aryl hydrocarbon receptor (AhR) ligand, indole-3-carbinol (I3C), was effective in the reduction of colitis-associated disease severity through innate lymphoid type 3 cells (ILC3s) in an interleukin-22 (IL-22) dependent manner. In one of our studies, we used single cell RNA sequencing (scRNAseq) analysis of colonic lamina propria cells from colitis models treated with I3C. Our results indicated that there were changes in the expressions of genes integral to IL-22 signaling when I3C was used …

Erlang-Distributed Seir Epidemic Models With Cross-Diffusion, Victoria Chebotaeva Aug 2024

Erlang-Distributed Seir Epidemic Models With Cross-Diffusion, Victoria Chebotaeva

Theses and Dissertations

We examine the effects of cross-diffusion dynamics in epidemiological models. Using reaction-diffusion dynamics to model the spread of infectious diseases, we focus on situations in which the movement of individuals is affected by the concentration of individuals of other categories. In particular, we present a model where susceptible individuals move away from large concentrations of infected and infectious individuals.

Our results show that accounting for this cross-diffusion dynamics leads to a noticeable effect on epidemic dynamics. It is noteworthy that this leads to a delay in the onset of epidemics and an increase in the total number of people infected. …

Toxoplasma gondii is a parasitic infection that can be transmitted in utero, resulting in fetal chorioretinitis and other long-term neurological outcomes. If diagnosed early, pregnancy-safe chemotherapeutics can prevent vertical transmission. Unfortunately, diagnosis of acute, primary infection among pregnant women remains neglected, particularly in low-and-middle-income countries. Clinically actionable diagnosis is complex due to the commonality of infection during childhood and early adulthood which spawn long-last antibody titers and historically unreliable direct molecular diagnostics. The current study employed a cross-sectional T. gondii perinatal surveillance study using digital PCR, a next generation molecular diagnostic platform, and a maternal-fetal outcomes survey to ascertain …

A Sensor-Based Simulation Method For Spatiotemporal Event Detection, Yuqin Jiang, Andrey A. Popov, Zhenlong Li, Michael E. Hodgson, Binghu Huang

Faculty Publications

Human movements in urban areas are essential to understand human–environment interactions. However, activities and associated movements are full of uncertainties due to the complexity of a city. In this paper, we propose a novel sensor-based approach for spatiotemporal event detection based on the Discrete Empirical Interpolation Method. Specifically, we first identify the key locations, defined as “sensors”, which have the strongest correlation with the whole dataset. We then simulate a regular uneventful scenario with the observation data points from those key locations. By comparing the simulated and observation scenarios, events are extracted both spatially and temporally. We apply this method …

Background: The birthrate of Black preterm (BPT) infants is 65% higher than White preterm (WPT) infants with a BPT mortality that is 2.3 times higher. The incidence of culture-positive late-onset sepsis is as high as 41% in very-preterm infants. The main purpose of this study was to examine thermal gradients and the heart rate in relation to the onset of infection. This report presents disparities in very-preterm infection incidence, bacteria, and mortality data amongst BPT and WPT infants. Methods: 367 preterms born at < 32 weeks gestational age (GA) between 2019–2023 in five neonatal intensive care units (NICUs) were enrolled to study the onset of infections and dispositions; REDCap data were analyzed for descriptive statistics. Results: The 362 infants for analyses included 227 BPTs (63.7%) and 107 WPTs (29.6%), with 28 infants of other races/ethnicities (Hispanic, Asian, and other), 50.6% female, mean GA of 27.66 weeks, and 985.24 g birthweight. BPT infants averaged 968.56 g at birth (SD 257.50), and 27.68 (SD 2.07) weeks GA, compared to WPT infants with a mean birthweight of 1006.25 g (SD 257.77, p = 0.2313) and 27.67 (SD 2.00, p = 0.982) weeks GA. Of the 426 episodes of suspected infections evaluated across all the enrolled infants, the incidence of early-onset sepsis (EOS) was 1.9%, with BPT infants having 2.50 times higher odds of EOS than WPT infants (p = 0.4130, OR (odds ratio) = 2.50, p_or = 0.408). The overall incidence of late-onset sepsis (LOS) was 10.8%, with LOS in 11.9% of BPT infants versus 9.3% (p = 0.489, OR = 1.21, p_or = 0.637) of WPT infants. BPT infants made up 69.2% of the 39 infants with Gram-positive infections vs. 25.6% for WPT infants; 16 infants had Gram-negative culture-positive infections, with 81.2% being BPT infants versus 18.8% being WPT infants. Of the 27 urinary tract infections, 78% were in BPTs. The necrotizing enterocolitis incidence was 6.9%; the incidence in BPT infants was 7.5% vs. 6.5% in WPT infants. The overall mortality was 8.3%, with BPTs at 8.4% vs. WPT infants at 9.3%, (p = 0.6715). Conclusions: BPTs had a higher rate of positive cultures, double the Gram-negative infections, a much higher rate of urinary tract infections, and a higher rate of mortality than their WPT counterparts. This study emphasizes the higher risk of morbidity and mortality for BPTs.

Objective:

To evaluate temporal trends in the prevalence of gram-negative bacteria (GNB) with difficult-to-treat resistance (DTR) in the southeastern United States. Secondary objective was to examine the use of novel β-lactams for GNB with DTR by both antimicrobial use (AU) and a novel metric of adjusted AU by microbiological burden (am-AU). Design:

Retrospective, multicenter, cohort. Setting:

Ten hospitals in the southeastern United States. Methods:

GNB with DTR including Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter spp. from 2015 to 2020 were tracked at each institution. Cumulative AU of novel β-lactams including ceftolozane/tazobactam, ceftazidime/avibactam, meropenem/vaborbactam, imipenem/cilastatin/relebactam, and cefiderocol in days of therapy (DOT) …

Introduction: Many research activities have focused on SARS-CoV-2 infection and subsequent COVID-19 respiratory illness during the pandemic. However, significant racial inequities emerged months after the COVID-19 pandemic began. The similarity between racial/ ethnic disparities in COVID-19 and those for other diseases raised awareness about the context for risk exposure and healthcare access. The purpose of this study is to examine social and structural determinants of health among COVID-19 survivors, carepartners, and the perspectives of healthcare stakeholders who experienced disruption during the early pandemic.
Material and methods: A purposive sample of interviews (n=9) and focus groups (n=10) were used to collect …
