Factors In The Probability Of Covid-19 Transmission In University Classrooms, Charles Connor

Numeracy

University students and faculty members need an effective strategy to evaluate and reduce the probability that an individual will become infected with COVID-19 as a result of classroom interactions. Models are developed here that consider the probability an individual will become infected as a function of: prevalence of the disease in the university community, number of students in class, number of class meetings, and transmission rate in the classroom given the presence of an infected individual. Absolute probabilities that an individual will become infected in a classroom environment cannot be calculated because some of these factors have unknown values. Nevertheless, …

Thrombospondin-1 Plays An Essential Role In Yes-Associated Protein Nuclear Translocation During The Early Phase Of Trypanosoma Cruzi Infection In Heart Endothelial Cells, Ashutosh Arun, Kayla J. Rayford, Ayorinde Cooley, Girish Rachakonda, Fernando Villalta, Siddharth Pratap, Maria F. Lima, Nader Sheibani, Pius N. Nde

Publications and Research

The protozoan parasite Trypanosoma cruzi is the causative agent of Chagas disease. This neglected tropical disease causes severe morbidity and mortality in endemic regions. About 30% of T. cruzi infected individuals will present with cardiac complications. Invasive trypomastigotes released from infected cells can be carried in the vascular endothelial system to infect neighboring and distant cells. During the process of cellular infection, the parasite induces host cells, to increase the levels of host thrombospondin-1 (TSP-1), to facilitate the process of infection. TSP-1 plays important roles in the functioning of vascular cells, including vascular endothelial cells with important implications in cardiovascular …

A Study On Ecological Distribution Of And Selected Gene Expression In Amblyomma Americanum: An Insight Into The Alpha-Galactose Allergy Caused By Tick Bites, Leah Cuthill

Electronic Theses & Dissertations

Ticks transmit a wide variety of pathogens including viruses, bacteria, protozoa, and helminthes to vertebrates. Their life cycle depends on blood meals from various hosts as well as on environmental conditions such as the temperature and habitat type. A newly recognized allergic disease has been identified and is characterized by a delayed reaction following the consumption of some mammalian meats. The allergy often results in life threatening reactions such as anaphylaxis, hives, and breathing problems 3-6 hours after the consumption of mammalian meat. Not everyone develops the allergy when they are bitten by a lone star tick, and the cause …

Immune checkpoint inhibitors (ICI) have shown positive results in patients with hepatocellular carcinoma (HCC). As liver function contributes to prognosis, its precise assessment is necessary for the safe prescribing and clinical development of ICI in HCC. We tested the accuracy of the albumin-bilirubin (ALBI) grade as an alternative prognostic biomarker to the Child-Turcotte-Pugh (CTP). In a prospectively maintained multi-centre dataset of HCC patients, we assessed safety and efficacy of ICI across varying levels of liver dysfunction described by CTP (A to C) and ALBI grade and evaluated uni- and multi-variable predictors of overall (OS) and post-immunotherapy survival (PIOS). We studied …

Background: Practice effects (PEs) are improvements in performance after repeated exposure to test materials, and typically viewed as a source of bias in repeated cogni- tive assessments. We aimed to determine whether characterizing PEs could also pro- vide a useful marker of early cognitive decline.

Methods: We conducted a systematic review of the literature, searching PsycInfo (Ebsco) and PubMed databases for articles studying PEs in aging and dementia pop- ulations. Articles published between 1920 and 2019 were included.

Result: We identified 259 articles, of which 27 studied PEs as markers of cognitive performance. These studies consistently showed that smaller, less-robust …

A Counterpoint Paper: Comments On The Electrocardiographic Part Of The 2018 Fourth Universal Definition Of Myocardial Infarction Endorsed By The International Society Of Electrocardiology And The International Society For Holter And Noninvasive Electrocardiology, Yochai Birnbaum, Miguel Fiol, Kjell Nikus, Javier Garcia Niebla, Ljuba Bacharova, Sergio Dubner, Wojciech Zareba, Peter W Macfarlane, Antonio Luiz Ribeiro, Iwona Cygankiewicz, Antoni Bayes De Luna

Faculty, Staff and Students Publications

The Fourth Universal Definition of Myocardial Infarction (FUDMI) focuses on the distinction between nonischemic myocardial injury and myocardial infarction (MI), along with the role of cardiovascular magnetic resonance, in order to define the etiology of myocardial injury. As a consequence, there is less emphasis on updating the parts of the definition concerning the electrocardiographic (ECG) changes related to MI. Evidence of myocardial ischemia is a prerequisite for the diagnosis of MI, and the ECG is the main available tool for (a) detecting acute ischemia, (b) triage, and (c) risk stratification upon presentation. This review focuses on multiple aspects of ECG …

Using A Timed Motor Task To Predict One-Year Functional Decline In Amnestic Mild Cognitive Impairment, Sydney Y. Schaefer, Andrew Hooyman, Kevin Duff

Physical Therapy Faculty Articles and Research

Affordable, noninvasive methods of predicting functional decline are needed for individuals at risk for Alzheimer’s disease. This study tested whether a timed upper-extremity motor task predicted functional decline over one year in 79 adults diagnosed with amnestic mild cognitive impairment. Participants completed subjective and objective measures of daily functioning at baseline and one year later. Motor task performance and delayed memory were also evaluated at baseline. Motor task performance was a significant predictor of one-year follow-up daily functioning, improving model fits by 18– 35%. Thus, motor behavior has potential to be an affordable enrichment strategy that is sensitive to functional …

Age is a non-modifiable risk factor for the inflammation that underlies age-associated diseases; thus, anti-inflammaging drugs hold promise for increasing health span. Cytokine profiling and bioinformatic analyses showed that Th17 cytokine production differentiates CD4+ T cells from lean, normoglycemic older and younger subjects, and mimics a diabetes-associated Th17 profile. T cells from older compared to younger subjects also had defects in autophagy and mitochondrial bioenergetics that associate with redox imbalance. Metformin ameliorated the Th17 inflammaging profile by increasing autophagy and improving mitochondrial bioenergetics. By contrast, autophagy-targeting siRNA disrupted redox balance in T cells from young subjects and activated the Th17 …

Trichosporon Species And Fusarium Species As A Cause Of Empyema Thoracis In A Diabetic Patient, Nousheen Iqbal, Muhammad Ammar, Muhammad Irfan, Kauser Jabeen

Section of Pulmonary & Critical Care

Of late, fungal infections are increasingly being recognized in diabetic patients. Here we present a case of polymicrobial fungal empyema due to Trichosporon species and Fusarium species developed after community-acquired pneumonia in a diabetic patient. Trichosporon species are basidiomycetous yeast and Fusarium species are soil saprophytes with a worldwide distribution. Fungal empyema cases are rare and are mostly caused by Aspergillus and Candida species. Polymicrobial fungal empyema with Trichosporon species and Fusarium species has not been reported previously. Our patient was successfully treated with antifungal therapy. This case highlights that fungal empyema should be considered in diabetic patients especially if …

Acute Kidney Injury, Mary Boadu

Nursing Student Class Projects (Formerly MSN)

This poster presents up to date information regarding acute kidney injury (AKI) which often presents in patients in the intensive care unit (ICU). Most patients may not have identifiable symptoms therefore, advanced practice clinicians are charged with a great responsibility to diagnose, treat and follow-up with such patients. It is pertinent that clinicians recognize AKI early in an effort to prevent adverse consequences as seen in the progression of AKI to chronic kidney disease (CKD).

How Can Econometrics Help Fight The Covid'19 Pandemic?, Kevin Alvarez, Vladik Kreinovich

Departmental Technical Reports (CS)

The current pandemic is difficult to model -- and thus, difficult to control. In contrast to the previous epidemics whose dynamics was smooth and well described by the existing models, the statistics of the current pandemic is highly oscillating. In this paper, we show that these oscillations can be explained if we take into account the disease's long incubation period -- as a result of which our control measures are determined by outdated data, showing number of infected people two weeks ago. To better control the pandemic, we propose to use the experience of economics, where also the effect of …

Fravell, Giorgio Trinchieri, M. Eric Gershwin, Howard A. Young

United States Public Health Resources

Low grade, chronic inflammation is a critical risk factor for immunologic dysfunction including autoimmune diseases. However, the multiplicity of complex mechanisms and lack of relevant murine models limit our understanding of the precise role of chronic inflammation. To address these hurdles, we took advantage of multi-omics data and a unique murine model with a low but chronic expression of IFN-γ, generated by replacement of the AU-rich element (ARE) in the 3’ UTR region of IFN-γ mRNA with random nucleotides. Herein, we demonstrate that low but differential expression of IFN-γ in mice by homozygous or heterozygous ARE replacement triggers distinctive gut …
