Breast Cancer Incidence In Black And White Women Stratified By Estrogen And Progesterone Receptor Statuses., Michael X. Gleason, Tengiz Mdzinarishvili, Simon Sherman

Journal Articles: Eppley Institute

BACKGROUND: There is increasing evidence that breast cancer is a heterogeneous disease presented by different phenotypes and that white women have a higher breast cancer incidence rate, whereas black women have a higher mortality rate. It is also well known that white women have lower incidence rates than black women until approximately age 40, when rate curves cross over and white women have higher rates. The goal of this study was to validate the risk of white and black women to breast cancer phenotypes, stratified by statuses of the estrogen (ER) and progesterone (PR) receptors.

METHODOLOGY/PRINCIPAL FINDINGS: SEER17 data were …

Alcohol Exposure Alters Mouse Lung Inflammation In Response To Inhaled Dust., Michael L. Mccaskill, Debra J. Romberger, Jane M. Devasure, Jessica Boten, Joseph H. Sisson, Kristina L. Bailey, Jill A. Poole, Todd A. Wyatt

Journal Articles: Pulmonary & Critical Care Med

Alcohol exposure is associated with increased lung infections and decreased mucociliary clearance. Occupational workers exposed to dusts from concentrated animal feeding operations (CAFOs) are at risk for developing chronic inflammatory lung diseases. Agricultural worker co-exposure to alcohol and organic dust has been established, although little research has been conducted on the combination effects of alcohol and organic dusts on the lung. Previously, we have shown in a mouse model that exposure to hog dust extract (HDE) collected from a CAFO results in the activation of protein kinase C (PKC), elevated lavage fluid cytokines/chemokines including interleukin-6 (IL-6), and the development of …

A Heuristic Solution Of The Identifiability Problem Of The Age-Period-Cohort Analysis Of Cancer Occurrence: Lung Cancer Example., Tengiz Mdzinarishvili, Simon Sherman

Journal Articles: Eppley Institute

BACKGROUND: The Age-Period-Cohort (APC) analysis is aimed at estimating the following effects on disease incidence: (i) the age of the subject at the time of disease diagnosis; (ii) the time period, when the disease occurred; and (iii) the date of birth of the subject. These effects can help in evaluating the biological events leading to the disease, in estimating the influence of distinct risk factors on disease occurrence, and in the development of new strategies for disease prevention and treatment.

METHODOLOGY/PRINCIPAL FINDINGS: We developed a novel approach for estimating the APC effects on disease incidence rates in the frame of …
