Faculty, Staff and Students Publications

Background/Objectives: Research on the association of adverse social determinants of health (SDOH) with severe pediatric coronavirus disease (COVID-19) is limited. We examined associations between SDOH patterns and COVID-19 severity in children.

Methods: We conducted a prospective, observational study of children (< 18 years) with symptomatic SARS-CoV-2 infection evaluated in an urban pediatric emergency department (March 2021-April 2022) in Detroit, Michigan. Caregivers completed a 34-item survey based on the Healthy People 2030 framework. Severe disease was defined as the occurrence of respiratory/cardiac failure or death within four weeks of diagnosis. Continuous and categorical variables were described using medians and percentages, respectively. Associations between disease severity and risk factors were determined using chi-square tests. Association rule mining was used for feature selection, followed by multivariate logistic regression.

Results: We analyzed data from 354 children [6-12 years: 31.1%, Female: 51.1%, Black: 59%, not Hispanic: 84.7%, public insurance: 77.1%, chronic condition: 27.4%]. Of the total, 113 children had severe disease. Most caregivers were 30-44 years old (53.1%), had less than a college degree (70.4%), and income < USD 50,000 (75.2%). Adverse SDOH reported included food/housing insecurity (24.6%), no support (64.7%), unmet childcare needs (35.9%), and lack of transportation (12.7%). After controlling for age, sex, medical history, income, and obesity, severe disease was associated with caregiver use of drugs/alcohol (OR:5.92, p < 0.001) and social discrimination/lack of support (OR: 1.74, p = 0.030).

Conclusions: Two SDOH patterns (caregiver use of drugs/alcohol …

Immune profiling data included PBMC transcriptomics, serum O-link and plasma proteomics, plasma metabolomics, and blood mass cytometry by time of flight (CyTOF) protein levels. Recovery factor …

A Literature Review Of The United States Of America’S Reliance On Imported Covid Personal Protective Equipment During The Pandemic, Pradip K. Shukla, Izzet Kosar, Hedieh Setayesh

Business Faculty Articles and Research

This paper provides a literature review of United States of America’s reliance on imported Covid Personal Protective Equipment (PPEs) during the Covid pandemic. The abstracted and cited articles show that the United States was too reliant on imported PPEs, primarily imported from Asia which led to shortages as the cases of Covid surged at various points during the waves of Covid cases. This supply and demand imbalance was not just an inconvenience such as the toilet paper shortage and other supply chain disruptions of basic commodities; this supply and demand imbalance had life and death impacts for many first responders, …

Learning From Covid-19: Clinical Trials, Health Information Technology, And Patient Mortality, Christos Nicolaides, Avinash Collis, Seth Benzell, Indranil Bardhan

Economics Faculty Articles and Research

During the COVID-19 pandemic, deaths per case in the United States decreased from 7.46% in April 2020 to 1.76% in April 2021. One mechanism that could explain this decline is a learning effect associated with testing of new treatments by hospitals. Hospitals that participated in clinical trials developed better organizational capabilities to diagnose and treat COVID-19 patients. Simultaneously, hospitals used health information technologies (IT) that integrated health information across healthcare providers to facilitate greater learning and sharing of best practices. Using US county-level data on clinical trial participation, use of health IT, and COVID-19 cases and deaths, we show that …

SARS-CoV-2 variants have demonstrated distinct epidemiological patterns and clinical presentations throughout the COVID-19 pandemic. Understanding variant-specific differences at the respiratory epithelium is crucial for understanding their pathogenesis. Here, we utilized human nasal organoid air-liquid interface (HNO-ALI) cell cultures to compare the viral replication kinetics, innate immune response, and epithelial damage of six different strains of SARS-CoV-2 (B.1.2, WA, Alpha, Beta, Delta, and Omicron). All variants replicated efficiently in HNO-ALIs, but with distinct replication kinetic patterns. The Delta variant exhibited delayed replication kinetics, achieving a steady state at 6 days post-infection compared to 3 days for other variants. Cytokine analysis revealed …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Faculty, Staff and Students Publications

The Hippo pathway controls organ development, homeostasis, and regeneration primarily by modulating YAP/TEAD-mediated gene expression. Although emerging studies report Hippo-YAP dysfunction after viral infection, it is largely unknown in the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we analyzed RNA sequencing data from human-induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) and SARS-CoV-2-infected human lung samples, and observed a decrease in YAP target gene expression. In screening SARS-CoV-2 nonstructural proteins, we found that nonstructural protein 13 (NSP13), a conserved coronavirus helicase, inhibits YAP transcriptional activity independent of the upstream Hippo kinases LATS1/2. Consistently, introducing NSP13 into mouse cardiomyocytes suppresses …

Causes Of Symptoms And Symptom Persistence In Long Covid And Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, Anthony L Komaroff, Robert Dantzer

Faculty, Staff and Student Publications

Debilitating symptoms for many years can follow acute COVID-19 ("long COVID"), myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and various post-acute infection syndromes (PAISs). Together, long COVID and ME/CFS affect 60-400 million individuals, globally. Many similar underlying biological abnormalities have been identified in both conditions including autoantibodies against neural targets, endothelial dysfunction, acquired mitochondrial dysfunction, and a pro-inflammatory gut microbiome. Each of these abnormalities may directly cause some of the symptoms. In addition, the symptoms also may be caused by ancient, evolutionarily conserved symptomatic and metabolic responses to vital threats-sickness behavior and torpor-responses mediated by specific, recently discovered neural circuits. These neural …

Adolescent Online Leisure, Media Literacy, Online Victimization, And Multifaceted Well-Being During Covid-19: The Role Of Parental Support, Yunqi Wang

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The rapid advancement of the internet and digital technology has provided opportunities for adolescents to conduct leisure activities online on a daily basis. However, research on adolescent technology use and mental health often highlights negative effects without carefully examining the specific mechanisms, which overlooks the complexity of effects of online behaviors on adolescent well-being and the importance of developing adolescents’ media literacy skills. Moreover, despite the crucial role of family dynamics in adolescent development, research on how parental support and involvement might affect adolescent technology use and well-being is still limited. The current study retrieved data from Programme for International …

The Tree That Would Not Fall: An Educator’S Autoethnographic Journey Of Healing Through Words, Raeanna Marie Carlson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

To say the world has changed since the 2020 COVID-19 shut down is to minimize the micro and macro social changes that infiltrated the school system. In the wake of it all, we find a landscape marred by a both rising teacher attrition and struggling student motivation. This autoethnographic dissertation explores the deeply personal experience tethered to a deeply problematic system that contributes to not only teacher burnout but what I came to know as teacher demoralization. Personal traumas of teachers profoundly impact their experience in the classroom, and as I examined my own near departure from the classroom, I …

Inequality And Covid Risk At School: Racial Disparities In Indoor Density, Vaccination Rates, And Consequences For Absenteeism, Michael C. Quinn, Michah W. Rothbart, Amy Ellen Schwartz, Brian Elbel

Center for Policy Research

During the COVID pandemic, schools were widely believed to be a venue that facilitated disease transmission. While some worried Black and Hispanic students would disproportionately face greater risk of COVID exposure at school (school COVID risk) – given well-documented racially disparate school environments and resources – little empirical evidence exists documenting or refuting potential disparities in school COVID risk. This paper begins to fill this gap by examining racial disparities in the school environments that contribute to COVID risk at school—specifically, vaccination rates and classroom space per pupil (indoor density) - in New York City elementary schools. We then document …

Multiscale Modeling And Dynamic Mutational Profiling Of Binding Energetics And Immune Escape For Class I Antibodies With Sars-Cov-2 Spike Protein: Dissecting Mechanisms Of High Resistance To Viral Escape Against Emerging Variants, Mohammed Alshahrani, Vedant Parikh, Brandon Foley, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

The rapid evolution of SARS-CoV-2 has underscored the need for a detailed understanding of antibody binding mechanisms to combat immune evasion by emerging variants. In this study, we investigated the interactions between Class I neutralizing antibodies—BD55-1205, BD-604, OMI-42, P5S-1H1, and P5S-2B10—and the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein using multiscale modeling, which combined molecular simulations with the ensemble-based mutational scanning of the binding interfaces and binding free energy computations. A central theme emerging from this work is that the unique binding strength and resilience to immune escape of the BD55-1205 antibody are determined by leveraging a broad epitope …
