The Impact Of Perceptions About Influenza And The Yearly Influenza Vaccine On Vaccine Behaviors Among Undergraduate Students At The University Of South Carolina, Julia G. Fuller 2020 University of South Carolina - Columbia

The Impact Of Perceptions About Influenza And The Yearly Influenza Vaccine On Vaccine Behaviors Among Undergraduate Students At The University Of South Carolina, Julia G. Fuller

Senior Theses

Background: Undergraduate students are at an increased risk for developing respiratory infections as a result of the proximity in which they live, study, and eat. Despite being a target population for the Centers for Disease Control and Prevention’s yearly flu vaccine, several studies of undergraduate populations have found vaccine uptake to be much lower than other at-risk populations. This study aims to understand how perceptions about influenza and the influenza vaccine affect University of South Carolina undergraduate students’ vaccine behavior. Methods: A cross-sectional study was completed using survey data from 165 undergraduate students at the University of South Carolina ...

The Efficacy Of An Educational Intervention To Improve Low Influenza Vaccination Rates Among Federal Health Care Workers, Cynthia Berfect-Shelby 2019 Abilene Christian University

The Efficacy Of An Educational Intervention To Improve Low Influenza Vaccination Rates Among Federal Health Care Workers, Cynthia Berfect-Shelby

Electronic Theses and Dissertations

Influenza is a preventable communicable illness that has a significant impact on people of all ages. In 2018 it was estimated that 80,000 people died of influenza-related illnesses. Infants and elderly people are among the most vulnerable populations. The Centers for Disease Control and Prevention and Healthy People 2020 recommend that health care facilities have a 90% vaccination rate. Despite the recommendations and a mandatory directive, many facilities within the Veterans Health Administration struggle to reach influenza vaccination rates above 60%. Pender’s health promotion model was used as the theoretical framework to explore the reasons why health care ...

Influenza infection increases the incidence of myocardial infarction but the reason is unknown. Platelets mediate vascular occlusion through thrombotic functions but are also recognized to have immunomodulatory activity. To determine if platelet processes are activated during influenza infection, we collected blood from 18 patients with acute influenza infection. Microscopy reveals activated platelets, many containing viral particles and extracellular-DNA associated with platelets. To understand the mechanism, we isolate human platelets and treat them with influenza A virus. Viral-engulfment leads to C3 release from platelets as a function of TLR7 and C3 leads to neutrophil-DNA release and aggregation. TLR7 specificity is confirmed ...

Assessment Of Pneumonia Severity Indices As Mortality Predictors, Connor L. English, Thomas Chandler, Brian E. Guinn, Stephen P. Furmanek, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

BACKGROUND

The leading cause of infectious disease death in the United States is community-acquired pneumonia (CAP). Several pneumonia severity indices exist and are widely used as tools to assist physicians regarding site of care based on risk of death. However, limited data exists that discerns which of the most commonly used severity scores is the best predictor of mortality across multiple time points. The objective of this study is to determine the best mortality predictor at different time points between four of the most commonly used pneumonia severity scores.

METHODS

This was a secondary analysis of a prospective, multicenter, population-based ...

Severity Of Disease And Mortality For Hospitalized Patients With Community-Acquired Viral Pneumonia Compared To Patients With Community-Acquired Bacterial Pneumonia, Richard Y. Kim, Thomas Chandler, Stephen P. Furmanek, Timothy Lee Wiemken, Rodrigo Cavallazzi

The University of Louisville Journal of Respiratory Infections

Background: There exists a large body of literature to help identify, diagnose, treat, and manage community-acquired pneumonia (CAP). Despite this, there is little data that directly compares the clinical syndromes and complications of pure bacterial pneumonia to pure viral pneumonia. Our study compares the clinical presentation, morbidity and mortality of viral vs. bacterial etiologies of CAP.

Methods: This was a secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) international study database. Data was collected concerning patient demographics, physical examination findings, laboratory findings, radiological findings, severity of illness, and clinical outcomes and stratified according to the two study groups, CAVP ...

Towards Multi-Lingual Pneumonia Research Data Collection Using The Community-Acquired Pneumonia International Cohort Study Database, William A. Mattingly, Kimberley A. Buckner, Senen Pena

The University of Louisville Journal of Respiratory Infections

Background: Although multilingual interfaces are preferred by most users when they have a choice, organizations are often unable to support and troubleshoot problems involving multiple user languages. Software that has been structured with multiple languages and data interlinking considerations early in its development is more likely to be easily maintained. We describe the process of adding multilingual support to the CAPO international Cohort study database using REDCap.

Methods: Using Google Translate API we extend the supported Spanish language version of REDCap to the most recent version used by CAPO, 8.1.4. We then translate the English data dictionary for ...


What Influences Our Decision To Vaccinate? The Social Amplification Of Risk Framework And Vaccination, Laura B. Carper 2019 Louisiana State University

What Influences Our Decision To Vaccinate? The Social Amplification Of Risk Framework And Vaccination, Laura B. Carper

International Crisis and Risk Communication Conference

The current study applies the social amplification risk framework to the anti-vaccination movement, specifically to the social factors that influence the likelihood to vaccinate. A total of 264 participants were recruited using Amazon’s Mechanical Turk engine and students from a large southern university. Participants responded to questions about their personal, friend, and family experiences with vaccines, their discussion about vaccines, and trust in vaccine literature (CDC, Facebook, family, etc.). Lastly, participants responded to a modified Duke’s social support scale. Results indicated that the likelihood to vaccinate is impacted by several social factors and that those factors can be ...

Collaborative Efforts To Forecast Seasonal Influenza In The United States, 2015–2016, Craig J. Mcgowan, Jarad Niemi, Nehemias Ulloa, Katie Will, Et Al.

Statistics Publications

Since 2013, the Centers for Disease Control and Prevention (CDC) has hosted an annual influenza season forecasting challenge. The 2015–2016 challenge consisted of weekly probabilistic forecasts of multiple targets, including fourteen models submitted by eleven teams. Forecast skill was evaluated using a modified logarithmic score. We averaged submitted forecasts into a mean ensemble model and compared them against predictions based on historical trends. Forecast skill was highest for seasonal peak intensity and short-term forecasts, while forecast skill for timing of season onset and peak week was generally low. Higher forecast skill was associated with team participation in previous influenza ...

Understanding Flu Vaccination Acceptance Among U.S. Adults: The Health Belief Model And Media Sources, Tong Xie, Connor Grady, Michael Cacciatore, Glen Nowak

International Crisis and Risk Communication Conference

Based on previous studies about the Health Belief Model (HBM) and the reinforcing relationship between media selectivity or preference and individual’s behavior, this study used a national representative adult sample to assess flu vaccination as the result of an appraisal of relevant health beliefs, trust towards the authoritative entities (e.g. CDC & FDA) and vaccine-related media information, in addition to one’s existing behavior pattern. Results showed that not-vaccinated individuals differ significantly in their vaccine-related health believes and the trust towards the authoritative information sources. This group acquired less recommendation from health care providers and more negative sentiments about ...

The University of Louisville Journal of Respiratory Infections

Background

Current guidelines recommend a β-lactam plus a macrolide or fluoroquinolone monotherapy as initial empiric antibiotic therapy for treatment of patients hospitalized with community-acquired pneumonia (CAP). Multiple studies have shown different results comparing the two regimens for the treatment of CAP. Our objective, in a city-wide prospective study, was to compare outcomes among hospitalized patients with CAP who received empiric treatment either with a β-lactam plus a macrolide or fluoroquinolone monotherapy.

Methods

This was a propensity score matched case-control study of the University of Louisville Pneumonia Study. It was a prospective population-based cohort study of all hospitalized adults with CAP ...


Wet Markets And Avian Influenza: Public Policy Decisions In Hong Kong, Shawn Smallman 2018 Portland State University

Wet Markets And Avian Influenza: Public Policy Decisions In Hong Kong, Shawn Smallman

Shawn C. Smallman

After the emergence of H5N1 avian influenza in 1997 Hong Kong implemented a sophisticated system to regulate live poultry markets. While this system is well implemented and thorough, it also has limitations. The rise of H7N9 avian influenza (which is typically acquired through contact with poultry, including in live markets) makes this an appropriate time to revisit the ethical and practical issues related to this trade. Based on data from field observations of live markets in Hong Kong, and interviews with experts in the field, this paper recommends that the government of Hong Kong create a committee to examine the ...

Maternal Immune Activation (Mia) In Mice: A Study To Phenotype Asd-Related Communication Behaviors And Analyze Maternal Health Outcomes In The Us, Komalpreet Gulati 2018 University of Connecticut

Maternal Immune Activation (Mia) In Mice: A Study To Phenotype Asd-Related Communication Behaviors And Analyze Maternal Health Outcomes In The Us, Komalpreet Gulati

Honors Scholar Theses

Core symptoms of Autism Spectrum Disorders (ASD) include deficits in social/communicative behaviors, and repetitive/stereotyped behaviors. Mouse models are a highly established paradigm used to study the phenotypic deficits that result from various inducible genotypic or environmental risk factors for ASD. Previous studies have demonstrated a link between maternal immune activation (MIA) and ASD-like behaviors in mouse models. In this model, the maternal immune system is activated during pregnancy by injecting the viral mimic poly(I:C). The resulting offspring are phenotyped and analyzed with regards to their communicative behaviors.

Previous studies have demonstrated that male pups born to ...

Influenza A virus (IAV), a major cause of human morbidity and mortality, continuously evolves in response to selective pressures. Stem-directed, broadly neutralizing antibodies (sBnAbs) targeting influenza hemagglutinin (HA) are a promising therapeutic strategy, but neutralization escape mutants can develop. We used an integrated approach combining viral passaging, deep sequencing, and protein structural analyses to define escape mutations and mechanisms of neutralization escape in vitro for the F10 sBnAb. IAV was propagated with escalating concentrations of F10 over serial passages in cultured cells to select for escape mutations. Viral sequence analysis revealed three mutations in HA and one in neuraminidase (NA ...
