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)
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)
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)
BACKGROUND 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. RESULTS Through simulation, we show that environmental adjustments that(More)
BACKGROUND Gene x 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 x environment interactions with respect to systolic blood pressure on sibships adjusting for repeated measures and hierarchical(More)
