Epigenetics And Social Inequalities In Asthma And Allergy, Elizabeth S. Clausing, Cassidy J. Tomlinson, Amy L. Non

School of Global Integrative Studies: Faculty Publications

Respiratory illnesses, such as asthma and allergy disorders, are disproportionately more common among minority racial/ethnic groups and those of low socioeconomic status. In the United States, asthma prevalence and severity are highest among Puerto Ricans (19.2%), American Indians/Alaska Natives (13%), and Black Americans (12.7%) and higher in families living below the poverty threshold than among those living above it (11% vs 8%–9%).¹ Many studies of asthma/allergy inequalities assume that genetic differences underlie racial/ethnic differences in these disorders, pointing to genetic ancestry differences between races, but most genetic variants fail to explain racial/ethnic differences and are usually studied only in …

The Relationship Between Pm2.5 And Chronic Respiratory Disease In Senegal, Bailey Glenn

Masters Theses

Chronic respiratory diseases such as asthma and chronic bronchitis have significantly increased in prevalence in Africa over the past 10 years. Recent studies have demonstrated that exposure to air pollution may be associated with an increased risk of chronic respiratory diseases. However, such studies have predominantly been conducted in western societies or often used urbanicity as a proxy for exposure to air pollution. Therefore, we evaluated the association between PM_2.5 exposure and asthma/chronic bronchitis in Senegal. A cross-sectional study was conducted for the time period of 3 October 2010 to 28 April 2011 using annual concentrations of PM_{2.5 …}

Examining The Pulmonary Response To Repeated Vishniacozyma Victoriae Exposure And Its Association With Allergic Airway Disease, Rachael Erin Rush

Graduate Theses, Dissertations, and Problem Reports

Allergic airway diseases such as asthma continue to increase in incidence in industrialized nations like the United States. These diseases are complex inflammatory processes involving numerous cells and mediators and are strongly influenced by fungal exposures. Recent developments in fungal detection methods have highlighted the contribution of Basidiomycota yeast species in indoor environments such as Vishniacozyma (syn. Cryptococcus) victoriae. However, despite the high levels of this yeast detected in indoor environments, very little is known about it or its role in respiratory morbidity. V. victoriae is phylogenetically similar to pathogenic Cryptococcus neoformans but lacks a capsule and is …

Allergy And Anaphylaxis From The Prehospital Perspective, Anthony E. Conrardy

Dissertations and Theses

Anaphylaxis is considered a severe, potentially fatal, systemic allergic reaction that occurs suddenly after contact with an allergy causing substance. It is estimated that up to 5% of the population has experienced anaphylaxis, with 1% of hospitalizations and 0.1% of emergency department patients having fatal outcomes. We characterized the population of patients encountered by the EMS agency (786 patients) that had a provider impression of “allergic reaction” and then utilized logistic regression models to estimate associations with the administration of epinephrine in the prehospital setting. Additionally, we used incident location data for all patient encounters of the EMS agency …

Asthma-Related Health Outcomes In New Jersey After A Natural Disaster Event, My Ngoc Thuy Nguyen

Health Services Research Dissertations

The occurrence of a natural disaster event such as a hurricane may further hinder the asthma management of asthmatic individuals. Unmanaged asthma has led to increased work absenteeism, preventable emergency department visits, costly hospitalizations and possibly death in severe cases. To improve asthma management in asthmatic adults in New Jersey (NJ) following a natural disaster event, this study examined whether predisposing, enabling and need factors are predictors for asthma exacerbation and asthma-related health care utilization in New Jersey. A retrospective secondary analysis of New Jersey Behavioral Risk Factor Surveillance System (NJBRFSS) data and New Jersey Asthma Call Back Survey (NJACBS) …

Ecological Determinants Of Respiratory Health: Examining Associations Between Asthma Emergency Department Visits, Diesel Particulate Matter, And Public Parks And Open Space In Los Angeles, California, Jason A. Douglas, Reginald S. Archer, Serena E. Alexander

Health Sciences and Kinesiology Faculty Articles

Los Angeles County (LAC) low-income communities of color experience uneven asthma rates, evidenced by asthma emergency department visits (AEDV). This has partly been attributed to inequitable exposure to diesel particulate matter (DPM). Promisingly, public parks and open space (PPOS) contribute to DPM mitigation. However, low-income communities of color with limited access to PPOS may be deprived of associated public health benefits. Therefore, this novel study investigates the AEDV, DPM, PPOS nexus to address this public health dilemma and inform public policy in at-risk communities. Optimized Hotspot Analysis was used to examine geographic clustering of AEDVs, DPM, and PPOS at the …

Turkey : Asthma, Nicole Adams

Global Public Health

In the Middle-Eastern country of Turkey, they have the public health issue of asthma which is directly related to the amount and type of air pollution. Asthma is a health condition that can be found all over the world and it can happen to anyone. Although it is not readily noticed, the number of cases of asthma change along with the amount of air pollution, specifically SO₂ and PM₁₀ levels. SO₂ is a gas that be toxic when abundant and it occurs when coal that has sulfur is burned. PM₁₀, or particulate matter, is the …

Association Of Ambient Ozone Exposure With Airway Inflammation And Allergy In Adults With Asthma, Sumita B. Khatri, Fernando C. Holguin, P. Barry Ryan, David M. Mannino, Serpil C. Erzurum, W. Gerald Teague

David M. Mannino

Rationale

Previous studies have demonstrated associations of high ozone levels with increased epidemiologic as well as lung function measures of asthma activity.

Objectives

In an observational study during the summer months, we hypothesized that higher ambient ozone levels are associated with more frequent symptoms, higher airway and systemic inflammation, as well as worse lung function in asthmatics as compared with non-asthmatic individuals.

Methods

Thirty-eight asthmatics and thirteen healthy control subjects residing in metropolitan Atlanta were enrolled during peak ozone season. Medical histories, quality-of-life questionnaires, spirometry, serum immunoglobulin (IgE), peripheral eosinophil counts, and exhaled nitric oxide (NO) were obtained during study …
