To determine whether geographic variability in rates of kidney stones in the United States was attributable to differences in personal and environmental exposures, the authors examined cross-sectional data that included information on self-reported, physician-diagnosed kidney stones collected from 1,167,009 men and women, aged > or = 30 years, recruited(More)
This article reviews the epidemiologic studies of the association of ischemic heart disease risk and environmental tobacco smoke (ETS) exposure from a spouse who smokes. Seventeen studies (nine cohort, eight case-control) comprising more than 485,000 lifelong nonsmokers and 7,345 coronary heart disease (CHD) events were included in a meta-analysis.(More)
Each year the American Cancer Society compiles estimates of the number of new cancer cases and deaths expected in the US in the current year and the most recent data on cancer incidence, mortality, and survival. An estimated 1,268,000 new cases of cancer will be diagnosed in the year 2001 and an estimated 553,400 Americans will die from cancer. Overall(More)
We sought to describe the changing death rates from lung cancer in the US white population in sequential birth cohorts, adjusting for cohort smoking prevalence and duration. We searched the US mortality database (1960-1994) for all deaths among whites in which lung cancer was listed as the underlying cause of death. To determine the population at risk for(More)
BACKGROUND We sought to describe trends in the presence of lung cancer at the time of death in the United States from 1979 to 1992. METHODS We analysed death certificate reports in the Multiple-Cause Mortality Files compiled by the National Center for Health Statistics, searching for any mention of lung cancer, lung cancer as the underlying cause of(More)
Fatal chemical pneumonia occurred in a worker following exposure to an unidentified gas in a salvaged cylinder. Inspection of the tank revealed a scrawled chemical formula for 1,1,2,3,3-pentafluoro-3-chloropropene, a suspected pulmonary irritant. The report underscores the potential hazards which salvaged cylinders pose to individuals who use or refill(More)
For the first time, a complex formed by poly-aniline (in its organic metal form) and silver has been deposited on copper in nanoparticulate form. When depositing on Cu pads of printed circuit boards it efficiently protects against oxidation and preserves its solderability. The deposited layer has a thickness of only nominally 50 nm, containing the Organic(More)
