Loss of heterozygosity (LOH) in chromosomal regions that harbor tumor suppressor genes from tumor tissue may lead to decreased survival time in cancer patients with squamous cell carcinoma of the head and neck (HNSCC). We studied 8 regions frequently lost in HNSCC in 150 patients having a primary diagnosis of HNSCC. Tumor and normal tissue DNA were(More)
BACKGROUND Several epidemiologic studies have suggested an association between Parkinson's disease (PD) and exposure to heavy metals using subjective exposure measurements. OBJECTIVES We investigated the association between objective chronic occupational lead exposure and the risk of PD. METHODS We enrolled 121 PD patients and 414 age, sex, and race,(More)
OBJECTIVES To determine whether certain occupations and occupationally related exposures were associated with a history of sarcoidosis in African-American siblings. METHODS We collected occupational data from 921 African Americans in 273 sibships that had been identified through a sarcoidosis case. Among the 648 siblings of sarcoidosis index cases(More)
OBJECTIVE To determine if there are significant differences in biochemical characteristics, biopsy variables, histopathological data, and rates of prostate-specific antigen (PSA) recurrence between African-American (AA) and white American (WA) men undergoing radical prostatectomy (RP), as AA men are twice as likely to die from prostate cancer than their(More)
Underreporting tuberculosis (TB) cases can compromise surveillance. We evaluated the contribution of pharmacy data in three different managed-care settings and geographic areas. Persons with more than two anti-TB medications were identified by using pharmacy databases. Active TB was confirmed by using state TB registries, medical record review, or(More)
Family-based association testing is an important part of genetic epidemiology. Tests are available to include multiple siblings, unaffected offspring, and to adjust for environmental covariates. We explore a susceptibility residual method of adjustment for covariates. Through simulation, we show that environmental adjustments that down-weight persons who(More)
Gene × environment models are widely used to assess genetic and environmental risks and their association with a phenotype of interest for many complex diseases. Mixed generalized linear models were used to assess gene × environment interactions with respect to systolic blood pressure on sibships adjusting for repeated measures and hierarchical nesting(More)
Part I of this Article provides a brief overview of the dominant discourse on linkages, which focuses on whether World Trade Organization (“WTO”) rules should be modified (or interpreted) to permit trade restrictions on environmental and labor rights grounds. Those fully familiar with the competing conventional approaches to trade-environment and(More)
