Neurology Articles

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is an immune-mediated disorder of small and medium-sized vessels, characterized by the production of autoantibodies that target the neutrophilic antigens leading to mononuclear cell infiltration and destruction of blood vessels in lungs, skin, and kidneys. Although rare, the coronavirus disease 2019 (COVID-19) vaccine may trigger autoimmune vasculitis. We report a rare case of ANCA-associated renal vasculitis following COVID-19 vaccination in a 59-year-old male who presented with flu-like symptoms and deranged renal function tests. He received his second dose of the Pfizer COVID-19 vaccine 17 days ago. His clinical picture, serological testing, and radiological imaging …

Diplomacy Syllabi

Global health issues have affected world history more extensively than most of us can imagine. As shown in the COVID-19 pandemic, international travel threatens transborder epidemics by transporting and spreading diseases globally at jet speed. The growing risk of exposure to infectious disease, coupled with the threat of intentional release of pathogens, creates a situation in which health and security are interacting with greater frequency and intensity. This development parallels efforts to redefine the concept of security to encompass new global challenges. This interdisciplinary course focuses on global health security by addressing the following questions: How did epidemics function as …

(Si10-077) A Novel Collocation Method For Solving Second-Order Volterra Integro-Differential Equations, Nimai Sarkar, Mausumi Sen, Pratiksha Jadli, Dipankar Saha

Applications and Applied Mathematics: An International Journal (AAM)

In this article, we present an efficient numerical methodology to solve second-order linear Volterra integro-differential equations. Further, the modified Chebyshev collocation method is used at the Gauss-Lobatto collocation points. In that context, some theoretical investigation related to error analysis is suggested through residual function. Numerical examples are also encountered to study the applicability of the present method. In order to get a vivid illustration of the efficiency, we present a comparative survey with three existing collocation methods.

Medical Martial Law: Towards A More Effective Pandemic Policy, John W. Bagby, Robert J. Aalberts, Chad G. Marzen

Southern Illinois University Law Journal

This article synthesizes the political-economic geography regime with existing political subdivision modeling to predict the legitimacy of various authorities that might order Medical Martial Law. Such “districting” authority, as limited by the Constitutional right to travel, reveals a range of authorities to declare and enforce remediation of emergencies under various legal frameworks within defined geographic areas. The primary interdisciplinary approach used here is public policy, political economy and economic geography. We demonstrate how the latter contributes greatly. First, the science of spatial understanding is offered by physical geographers for the physical barriers that shape political borders and may define contagion …

As the positivity rate increases sharply, this study is pertinent in the fight against the virus. The implementation of MERV filters and ventilation rates while also understanding respiratory droplets and how they move through the air is an important part of understanding airborne transmission. Much research has been done on MERV filtration and respiratory droplets and their traveling methods in the air, and this research aims to find the commonalities between prior research, and …

Measuring The Impact Of Thermal Stress On Coral Resilience In Hawai'i Using Large-Area Imagery, Caroline Rodriguez

Capstone Projects and Master's Theses

Coral reefs worldwide are declining due to several anthropogenic stressors, but rising ocean temperature is the most serious threat to coral reef persistence. Developing models that document changes in coral communities following thermal stress events and forecast trends in reef recovery is crucial in identifying resilient reefs. Traditional approaches to generating the coral vital rates necessary for demographic modeling are time consuming and field intensive; however, by leveraging Structure-from-Motion photogrammetry, we can accurately track populations over time at a large spatial scale. In this study, I assessed the population dynamics of the dominant coral species across the Hawaiian archipelago and …

Increasing evidence shows that the host gut microbiota might be involved in the immunological cascade that culminates with the formation of tissue granulomas underlying the pathophysiology of hepato-intestinal schistosomiasis. In this study, we investigated the impact of Schistosoma mansoni infection on the gut microbial composition and functional potential of both wild type and microbiome-humanized mice. In spite of substantial differences in microbiome composition at baseline, selected pathways were consistently affected by parasite infection. The gut microbiomes of infected mice of both lines displayed, amongst other features, enhanced capacity for tryptophan and butyrate production, which might be linked to the activation …

Faculty, Staff and Students Publications

BACKGROUND: Antimicrobial resistance is a global health threat. To slow resistance and preserve antibiotics, stewardship interventions are increasingly promoted and mandated. Urine cultures are the most common microbiological test in the outpatient setting. Contamination most likely occurs during urine collection from surrounding vaginal, perineal, and epidermal flora. Sample contamination can lead to incorrect diagnosis, unnecessary or inappropriate treatment, poor patient outcomes, and higher costs. Therefore, ensuring proper collection of urinary samples serves as a prime diagnostic stewardship target, one that international nursing societies increasingly endorse as an opportunity for nurse involvement.

OBJECTIVES: Determine the prevalence, predictors, and antibiotic prescribing associated …

Quantitative Single-Cell Analysis Of Leishmania Major Amastigote Differentiation Demonstrates Variably Extended Expression Of The Lipophosphoglycan (Lpg) Virulence Factor In Different Host Cell Types, Michael A. Mandell, Wandy L. Beatty, Stephen M. Beverley

2020-Current year OA Pubs

Immediately following their deposition into the mammalian host by an infected sand fly vector, Leishmania parasites encounter and are engulfed by a variety of cell types. From there, parasites may transit to other cell types, primarily macrophages or dendritic cells, where they replicate and induce pathology. During this time, Leishmania cells undergo a dramatic transformation from the motile non-replicating metacyclic stage to the non-motile replicative amastigote stage, a differentiative process that can be termed amastigogenesis. To follow this at the single cell level, we identified a suite of experimental 'landmarks' delineating different stages of amastigogenesis qualitatively or quantitatively, including new …

Spatial And Age Disparities In Covid-19 Outcomes, Qian Huang

Theses and Dissertations

COVID-19 has caused significant social, economic, environmental, and political impacts globally and affected communities unequally in the U.S. The pandemic has also sparked interest in age-specific manifestations of infection, for example, studies confirmed the risk of increasing age with COVID-19 severity. However, the nonstationarity effects of health determinants among age groups have not been well examined. This study aims to explore the nonstationarity effects of social, behavioral, environmental, health care access, and political contexts on COVID-19 outcomes. This study poses three broad questions: 1) how did COVID-19 vaccinations align with COVID-19 daily cases and deaths in the United States; 2) …
