Aim: To examine the epidemiology and the morphology of the proximal sessile serrated adenomas (SSAs).

Methods: We conducted a retrospective study to identify patients with SSAs using a university-based hospital pathology database query from January 2007 to April 2011. Data collected included: age, gender, ethnicity, body mass index, diabetes, smoking, family history of colorectal cancer, aspirin, and statin use. We collected data on morphology of SSAs including site (proximal or distal), size, and endoscopic appearance (flat or protuberant). We also compared proximal SSAs to proximal tubular adenomas detected during same time period.


Racial/Ethnic Disparities In Infectious Disease Hospitalizations In Arizona, Laura Callinan, Robert Holman, Douglas Esposito, Marian McDonald 2013 Centers for Disease Control and Prevention

Racial/Ethnic Disparities In Infectious Disease Hospitalizations In Arizona, Laura Callinan, Robert Holman, Douglas Esposito, Marian Mcdonald

Journal of Health Disparities Research and Practice

Infectious disease (ID) hospitalizations in Arizona, a diverse population with nearly complete race/ethnicity data, were analyzed using the State Inpatient Database for 2005-2008. ID hospitalizations rates were calculated and compared by ID group, race/ethnicity, age, and sex. During 2005-2008, there were 383,597 ID hospitalizations reported in Arizona, resulting in an age-adjusted rate of 1498.1 per 100,000 persons. A range of racial/ethnic disparities in ID hospitalization rates were noted. Persons of Native American and black race/ethnicity had overall ID hospitalization rates higher than the rate for persons of white race/ethnicity; persons of Asian or Pacific Islander race/ethnicity had a lower rate. …

Epidemiology Faculty Publications

Background

Global hypomethylation of repetitive DNA sequences is believed to occur early in tumorigenesis. There is a great interest in identifying factors that contribute to global DNA hypomethylation and associated cancer risk. We tested the hypothesis that plasma S-adenosylmethionine (SAM) level alone or in combination with genetic variation in DNA methyltransferases (DNMT1, DNMT3A andDNMT3B) was associated with global DNA methylation extent at long interspersed nucleotide element-1 (LINE-1) sequences.

Methods

Plasma SAM level and LINE-1 DNA methylation index were measured using stored blood samples collected from 440 healthy Singaporean Chinese adults during 1994-1999. Genetic polymorphisms of …


Procedural Rates, Economic Costs, And Geographic Variation Of Primary And Revision Lumbar Total Disc Replacement, Anthony J. Wheeler 2013 Utah State University

Procedural Rates, Economic Costs, And Geographic Variation Of Primary And Revision Lumbar Total Disc Replacement, Anthony J. Wheeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lumbar total disc replacement (TDR) surgery is a new procedure that treats degenerative disc disease, a remarkably common, disabling, and costly condition. Three distinct studies were conducted to address the longevity, costs, and geographic variation of the lumbar TDR procedure.

These three studies found lumbar TDR to have a revision burden and economic revision burden that has remained consistent since this procedure’s introduction in the
mid-2000s. The economic revision burden made this a lower-cost procedure than lumbar fusion, with a tradeoff in terms of revision burden being higher for lumbar TDR. The overall rate at which this procedure is performed …

Attributing Effects To Interactions, Tyler J. VanderWeele, Eric J. Tchetgen Tchetgen 2013 Harvard University

Attributing Effects To Interactions, Tyler J. Vanderweele, Eric J. Tchetgen Tchetgen

Harvard University Biostatistics Working Paper Series

A framework is presented which allows an investigator to estimate the portion of the effect of one exposure that is attributable to an interaction with a second exposure. We show that when the two exposures are independent, the total effect of one exposure can be decomposed into a conditional effect of that exposure and a component due to interaction. The decomposition applies on difference or ratio scales. We discuss how the components can be estimated using standard regression models, and how these components can be used to evaluate the proportion of the total effect of the primary exposure attributable to …


Population Cancer Risks Associated With Coal Mining: A Systematic Review, Wiley D. Jenkins, W. Jay Christian, Georgia Mueller, K. Thomas Robbins 2013 Southern Illinois University

Population Cancer Risks Associated With Coal Mining: A Systematic Review, Wiley D. Jenkins, W. Jay Christian, Georgia Mueller, K. Thomas Robbins

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this regard.

METHODS: We performed a systematic review of English-language manuscripts published since 1980 to determine if coal mining exposure was associated with increased cancer risk (incidence and mortality).

RESULTS: Of 34 studies identified, 27 studied coal mining as an occupational exposure …

Epidemiology Faculty Publications

Sulphonylureas (SUs) are widely used glucose-lowering agents in type 2 diabetes mellitus (T2DM) with apparent declining efficacy over time. Concerns have been raised from observational retrospective studies on the cardiovascular (CV) safety of SUs but there are few long-term data on CV outcomes from randomized controlled trials (RCTs) involving the use of this class of agents. Most of the observational studies and registry data are conflicting and vary with study population and methodology used for analyses. To address the SU controversy, we reviewed the recently published literature (until end of the year 2011) to evaluate the impact of SUs on …


The Epidemiology Of Human Herpesvirus-8: Transmission Of Infection To Children In Zambian Households, Kay L. Crabtree 2013 University of Nebraska-Lincoln

The Epidemiology Of Human Herpesvirus-8: Transmission Of Infection To Children In Zambian Households, Kay L. Crabtree

School of Biological Sciences: Dissertations, Theses, and Student Research

Human Herpes virus-8 (HHV-8) is the known etiologic agent for several malignant pathologies, including Kaposi’s sarcoma (KS), the most common tumor in children in sub-Saharan Africa. Saliva is implicated as the culprit of transmission; however there is a paucity of information regarding transmission to young children. In this study, we investigated the hypothesis that household behaviors exposing the susceptible child to saliva increase the risk of transmission of HHV-8 to that child.

To test our hypothesis a large prospective cohort study in Lusaka, Zambia, enrolling 464 young children and their households, was followed for 48 months. Socio-demographics, health histories, feeding …

Empowerment-Based Positive Youth Development: A New Understanding Of Healthy Development For African American Youth, Raphael Travis Jr., Tamara Leech 2013 Texas State University - San Marcos

Empowerment-Based Positive Youth Development: A New Understanding Of Healthy Development For African American Youth, Raphael Travis Jr., Tamara Leech

Department of Public Health Scholarship and Creative Works

A shift occurred in research about adolescents in the general population. Research is moving away from deficits toward a resilience paradigm and understanding trajectories of positive youth development. This shift has been less consistent in research and practice with African American youth. A gap also exists in understanding whether individual youth development dimensions generate potential in other dimensions. This study presents an empowerment-based positive youth development model. It builds upon existing research to present a new vision of healthy development for African American youth that is strengths-based, developmental, culture-bound, and action-oriented. It emphasizes the relationship between person and environment, the …

Purdue Policy Research Institute (PPRI) Policy Briefs

Managing HIV/AIDS presents challenges to public health policymakers, frontline workers, and researchers worldwide. A key strategy in the disease management is early diagnosis and rapid treatment initiation. While the technological field of point‐of‐care HIV/AIDS diagnostics has advanced significantly in the past two decades, several critical issues remain that hinder the deployment of point‐of‐care testing devices in resource‐deprived settings. In this policy brief, we discuss these issues, including technological specifics of point‐of‐care CD4+ T‐cell counting approaches and requirements of deploying them. We also discuss cultural and religious concerns on the deployment. At the end of the brief, we propose a …

When To Start Antiretroviral Therapy: The Need For An Evidence Base During Early Hiv Infection, James D. Lundgren, Abdel G. Babiker, Fred M. Gordin, Alvaro H. Borges, James D. Neaton

Epidemiology Faculty Publications

Background

Strategies for use of antiretroviral therapy (ART) have traditionally focused on providing treatment to persons who stand to benefit immediately from initiating the therapy. There is global consensus that any HIV+ person with CD4 counts less than 350 cells/μl should initiate ART. However, it remains controversial whether ART is indicated in asymptomatic HIV-infected persons with CD4 counts above 350 cells/μl, or whether it is more advisable to defer initiation until the CD4 count has dropped to 350 cells/μl. The question of when the best time is to initiate ART during early HIV infection has always been vigorously debated. The …
