Impact Of Simultaneous Exposure To Arboviruses On Infection And Transmission By Aedes Aegypti Mosquitoes, Claudia Rückert, James Weger-Lucarelli, Selene M. Garcia-Luna, Michael C. Young, Alex D. Byas, Reyes A. Murrieta, Joseph R. Fauver, Gregory D. Ebel

Journal Articles: Epidemiology

The recent emergence of both chikungunya and Zika viruses in the Americas has significantly expanded their distribution and has thus increased the possibility that individuals may become infected by more than one Aedes aegypti-borne virus at a time. Recent clinical data support an increase in the frequency of coinfection in human patients, raising the likelihood that mosquitoes could be exposed to multiple arboviruses during one feeding episode. The impact of coinfection on the ability of relevant vector species to transmit any of these viruses (that is, their vector competence) has not been determined. Thus, we here expose Ae. aegypti mosquitoes …

Exploring Job Satisfaction And Preceptorship Capacity Among Applied Epidemiologists, Jessica C. Arrazola

College of Graduate Studies: Theses & Dissertations

Job satisfaction is important to consider when developing strategies for recruitment and retention. The Public Health Workforce Interests and Needs Survey (PH WINS) conducted in 2014 was the first nationally representative assessment of the state public health workforce. Prior to this assessment, the job satisfaction of state agency public health workers and preceptor capacity had not been measured. This study fills the current research gaps by studying the job satisfaction among the applied epidemiology workforce, identifying factors influencing job satisfaction, and the describing the preceptorship capacity among epidemiologists. This research is based on the 2014 PH WINS data. The analysis …

Application Of The Misclassification Simulation Extrapolation (Mc-Simex) Procedure To Log-Logistic Accelerated Failure Time (Aft) Models In Survival Analysis, Varadan Sevilimedu

College of Graduate Studies: Theses & Dissertations

Survival analysis is the study of time to event outcomes. Accelerated Failure Time models (AFT) serve as a useful tool in survival analysis to study the time of occurrence of an event and its relation to the covariates of interest. The accuracy of estimation of parameters in a model depends upon the correct measurement of covariates. Considering that perfect measurement of covariates is highly unlikely, it is imperative that the performance of the existing bias-correction methods be analyzed in AFT models. However, certain areas of bias-correction in AFT models still remain unexplored. One of these unexplored areas, is a situation …

A Neighborhood-Wide Association Study (Nwas): Example Of Prostate Cancer Aggressiveness, Shannon M. Lynch, Nandita Mitra, Michelle Ross, Craig Newcomb, Karl Dailey, Tara Jackson, Charnita M. Zeigler-Johnson, Harold Riethman

School of Medical Diagnostics & Translational Sciences Publications

Purpose

Cancer results from complex interactions of multiple variables at the biologic, individual, and social levels. Compared to other levels, social effects that occur geospatially in neighborhoods are not as well-studied, and empiric methods to assess these effects are limited. We propose a novel Neighborhood-Wide Association Study(NWAS), analogous to genome-wide association studies(GWAS), that utilizes high-dimensional computing approaches from biology to comprehensively and empirically identify neighborhood factors associated with disease.

Methods

Pennsylvania Cancer Registry data were linked to U.S. Census data. In a successively more stringent multiphase approach, we evaluated the association between neighborhood (n = 14,663 census variables) and prostate …

Relationship Between Assisted Reproductive Technology And Risk Of Stillbirth, Jeani Chang
