Occupational Chronic Obstructive Pulmonary Disease: An Update, Enrique Diaz-Guzman, David M. Mannino, Shambhu Aryal

David M. Mannino

Chronic obstructive pulmonary disease represents a major cause of morbidity and mortality in industrialized and nonindustrialized countries. Although tobacco use remains the main factor associated with development of the disease, occupational risk factors represent an important and preventable cause. The most common occupationally related factors include exposure to organic dusts, metallic fumes, and a variety of other mineral gases and/or vapors. This article summarizes the literature on the subject and provides an update of the most recent advances in the field.

Characterization Of Microflora In Latin-Style Cheeses By Next-Generation Sequencing Technology, Tina S. Lusk, Andrea R. Ottesen, James R. White, Marc W. Allard, Eric W. Brown, Julie A. Kase

Environmental and Occupational Health Faculty Publications

Background

Cheese contamination can occur at numerous stages in the manufacturing process including the use of improperly pasteurized or raw milk. Of concern is the potential contamination by Listeria monocytogenes and other pathogenic bacteria that find the high moisture levels and moderate pH of popular Latin-style cheeses like queso fresco a hospitable environment. In the investigation of a foodborne outbreak, samples typically undergo enrichment in broth for 24 hours followed by selective agar plating to isolate bacterial colonies for confirmatory testing. The broth enrichment step may also enable background microflora to proliferate, which can confound subsequent analysis if not inhibited …

A number of topics are addressed, including distinguishing between curricula evaluation and evaluation of outcomes, types of evaluation, identifying …

Using Physiologically-Based Pharmacokinetic Models To Incorporate Chemical And Non-Chemical Stressors Into Cumulative Risk Assessment: A Case Study Of Pesticide Exposures, Susan C. Wason, Thomas J. Smith, Melissa J. Perry, Jonathan I. Levy

Environmental and Occupational Health Faculty Publications

Cumulative risk assessment has been proposed as an approach to evaluate the health risks associated with simultaneous exposure to multiple chemical and non-chemical stressors. Physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) models can allow for the inclusion and evaluation of multiple stressors, including non-chemical stressors, but studies have not leveraged PBPK/PD models to jointly consider these disparate exposures in a cumulative risk context. In this study, we focused on exposures to organophosphate (OP) pesticides for children in urban low-income environments, where these children would be simultaneously exposed to other pesticides (including pyrethroids) and non-chemical stressors that may modify the effects of these exposures …

Prioritization Of Biomarker Targets In Human Umbilical Cord Blood: Identification Of Proteins In Infant Blood Serving As Validated Biomarkers In Adults, Nicole Hansmeier, Tzu-Chiao Chao, Lynn R. Goldman, Frank R. Witter, Rolf U. Halden

Environmental and Occupational Health Faculty Publications

Background: Early diagnosis represents one of the best lines of defense in the fight against a wide array of human diseases. Umbilical cord blood (UCB) is one of the first easily available diagnostic biofluids and can inform about the health status of newborns. However, compared with adult blood, its diagnostic potential remains largely untapped.

Objectives: Our goal was to accelerate biomarker research on UCB by exploring its detectable protein content and providing a priority list of potential biomarkers based on known proteins involved in disease pathways.

Methods: We explored cord blood serum proteins by profiling a UCB pool of 12 …

Effects Of Temperature On Emergence And Seasonality Of West Nile Virus In California, David M. Hartley, Christopher M. Barker, Arnaud Le Menach, Tianchan Niu, Holly Gaff, William K. Reisen

Biological Sciences Faculty Publications

Temperature has played a critical role in the spatiotemporal dynamics of West Nile virus transmission throughout California from its introduction in 2003 through establishment by 2009. We compared two novel mechanistic measures of transmission risk, the temperature-dependent ratio of virus extrinsic incubation period to the mosquito gonotrophic period (BT), and the fundamental reproductive ratio (R₀) based on a mathematical model, to analyze spatiotemporal patterns of receptivity to viral amplification. Maps of BT and R₀ were created at 20-km scale and compared throughout California to seroconversions in sentinel chicken flocks at half-month intervals. Overall, estimates of BT and …

Background: Chromosomal abnormalities contribute substantially to reproductive problems, but the role of environmental risk factors has received little attention.

Objectives: We evaluated the association of polychlorinated biphenyl (PCB) and dichlorodiphenyldichloroethylene (p,p´-DDE) exposures with sperm sex-chromosome disomy.

Methods: We conducted a cross-sectional study of 192 men from subfertile couples. We used multiprobe fluorescence in situ hybridization (FISH) for chromosomes X, Y, and 18 to determine XX, YY, XY, and total sex-chromosome disomy in sperm nuclei. Serum was analyzed for concentrations of 57 PCB congeners and p,p´-DDE. Poisson regression models were used to calculate incidence rate ratios (IRRs) for …

Influence Of Ph On The Transport Of Silver Nanoparticles In Saturated Porous Media: Laboratory Experiments And Modeling, Jason R. Flory

Theses and Dissertations

Given the ubiquity of silver nanoparticles (AgNPs), the largest and fastest growing category of nanomaterials, and their potential for toxic effects to both humans and the environment, it is important to understand their environmental fate and transport. The purpose of this study is to gain information on the transport properties of unmodified AgNP suspensions in a glass bead-packed column under saturated flow conditions at different solution pH levels. Commercial AgNPs were characterized using high resolution transmission spectroscopy (HRTEM), dynamic light scattering (DLS) and ultraviolet (UV) visible spectroscopy. Transport data were collected at different pH levels (4, 6.5 and 9) at …

The Significance Of Race For Neighborhood Social Cohesion: Perceived Difficulty Of Collective Action In Majority Black Neighborhoods, Tamara Leech, Tara Hobson-Prater

Department of Public Health Scholarship and Creative Works

This article explores William Julius Wilson's contentions about community cultural traits by examining racial differences in middle class neighborhoods' levels of social cohesion. Specifically, we explore the perceived difficulty of these actions-as opposed to general pessimism about their outcomes-as a potential explanation for low levels of instrumental collective action in Black middle class neighborhoods. Our results indicate that, regardless of other neighborhood factors, majority Black neighborhoods have low levels of social cohesion. We also find that this racial disparity is statistically explained by shared perceptions about the amount of effort required to engage in group action in different neighborhoods. These …

College Student Perceptions On Campus Alcohol Policies And Consumption Patterns, Brenda L. Marshall, Katherine J. Roberts, Joseph Donnelly, Imani N. Rutledge

Department of Public Health Scholarship and Creative Works

Environmental strategies for colleges and universities to reduce alcohol consumption among their students include the development and enforcement of campus alcohol policies. This study examines students' knowledge and attitudes toward campus alcohol policies and how they relate to alcohol consumption and alcohol social norms. A sample of 422 freshman students was surveyed during their first month at a 4-year public college. Findings indicated that the majority of students (89%) were aware of campus policies, yet of those who were aware, less than half (44%) were accepting of these campus rules and regulations. In addition, the majority (79%) of students drank …

Environmental and Occupational Health Faculty Publications

Background

A growing body of empirical evidence indicates that low-level social capital is related to poor mental health outcomes. However, the prospective association between social capital and depression remains unclear, and no published studies have investigated the association with longitudinal data in East-Asian countries.

Methods

We analyzed data from the ongoing Korean Welfare Panel Study to prospectively investigate association between social capital and depression. Social capital was measured at the individual level by two items specific to interpersonal trust and reciprocity. Depression was annually assessed as a dichotomous variable using the Center for Epidemiologic Studies Depression Scale. After excluding participants …

Perceived Discrimination And Self-Rated Health In South Korea: A Nationally Representative Survey, Seung-Sup Kim, David R. Williams

Environmental and Occupational Health Faculty Publications

There is mounting evidence that discriminatory experiences can harm health. However, previous research has mainly focused on the health effects of racial discrimination in U.S. or European countries although there is pervasive discrimination by gender, age, education and other factors in Asian countries.

Methods

We analyzed the data from the 7th wave of Korean Labor and Income Panel Study to investigate the association between perceived discriminatory experience and poor self-rated health in South Korea. Perceived discriminatory experiences were measured in eight situations through a modified Experience of Discrimination questionnaire. In each of eight situations, the lifetime prevalence of perceived …

Measuring Discrimination In South Korea: Underestimating The Prevalence Of Discriminatory Experiences Among Female And Less Educated Workers?., Seung-Sup Kim, Yeonseung Chung, David R. Williams

Environmental and Occupational Health Faculty Publications

Objectives

To investigate the possibility that Koreans show different patterns in reporting discriminatory experiences based on their gender and education level, we analyzed the participants who answered “Not Applicable” for the questions of discriminatory experiences that they were eligible to answer.

Methods

Discriminatory experiences in eight social situations were assessed using the 7th wave of Korean Labor and Income Panel Study. After restricting the study population to waged workers, a logistic regression model was constructed to predict the probability that an individual has experienced discrimination based on the observed covariates for each of eight situations, using the data of participants …

Sociology & Criminal Justice Faculty Publications

Diffusion of innovation (DOI) is widely cited in the HIV behavior change literature; however there is a dearth of research on the application of DOI in interventions for sex workers. Following a randomized-controlled trial of HIV risk reduction among female entertainment workers (FEWs) in Shanghai, China, we used qualitative approaches to delineate potential interpersonal communication networks and contributing factors that promote diffusion of information in entertainment venues. Results showed that top-down communication networks from the venue owners to the FEWs were efficient for diffusion of information. Mammies/madams, who act as intermediaries between FEWs and clients form an essential part of …

The Effect Of Disinfectants, Cleaning, And Drying Practices On Oriental Rugs Flooded With Contaminated River Water: Public Health And Policy Implications, Daniel Bernazzani

Antioch University Dissertations & Theses

Oriental rugs contaminated with Category 3 floodwater potentially harbor environmental bacteria known to be human pathogens. River water inoculated with three species of gram positive and gram negative environmental bacteria (Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa) were used to assess the effectiveness of disinfectant type, cleaning methodology and drying practices by examining the survival rates of bacteria. Rug sections were immersed for one hour in contaminated water, saturated in one of three EPA registered disinfectant products (Phenol, Quaternary chloride, and Thyme oil) or tap water as a control, followed by cleaning and drying. The results showed that all disinfectants reduced …
