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 …

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 …

Environmental Exposure To Polychlorinated Biphenyls And P,P'-Dde And Sperm Sex-Chromosome Disomy, Megan E. Mcauliffe, Paige L. Williams, Susan A. Korrick, Larisa M. Altshul, Melissa J. Perry

Environmental and Occupational Health Faculty Publications

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 …

Association Of Hexachlorobenzene (Hcb), Dichlorodiphenyltrichloroethane (Ddt), And Dichlorodiphenyldichloroethylene (Dde) With In Vitro Fertilization (Ivf) Outcomes., Shruthi Mahalingaiah, Stacey A. Missmer, Arnab Maity, Paige L. Williams, John D. Meeker, Katharine Berry, Shelley Ehrlich,, Melissa J. Perry, Daniel W. Cramer, Russ Hauser

Environmental and Occupational Health Faculty Publications

Background: Hexachlorobenzene (HCB), dichlorodiphenyltrichloroethane (DDT), and dichlorodiphenyldichloroethylene (DDE) are persistent chlorinated pesticides with endocrine activity that may adversely affect the early stages of human reproduction.

Objective: Our goal was to determine the association of serum levels of HCB, DDT, and DDE with implantation failure, chemical pregnancy, and spontaneous abortion in women undergoing in vitro fertilization (IVF) from 1994 to 2003.

Methods: Levels of HCB and congeners of DDT and DDE were measured in serum collected during the follicular phase. Multivariable-adjusted statistical models accommodating multiple outcomes and multiple cycles per woman were used to estimate the relation between serum pesticide levels …

Association Between Interpersonal Trust, Reciprocity, And Depression In South Korea: A Prospective Analysis, Seung-Sup Kim, Yeonseung Chung, Melissa J. Perry, Ichiro Kawachi, V. S. Subramanian

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

Background

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 …
