- Abstract
Background: Cigarette smoking is a well-established risk factor for bladder cancer. The effects of smoking duration, intensity (cigarettes per day), and total exposure (pack-years); smoking cessation; exposure to environmental tobacco smoke; and changes in the composition of tobacco and cigarette design over time on risk of bladder cancer are unclear.Methods: We examined bladder cancer risk in relation to smoking practices based on interview data from a large, population-based case-control study conducted in Maine, New Hampshire, and Vermont from 2001 to 2004 (N = 1170 urothelial carcinoma case patients and 1413 control subjects). We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using unconditional logistic regression. To examine changes in smoking-induced bladder cancer risk over time, we compared odds ratios from New Hampshire residents in this study (305 case patients and 335 control subjects) with those from two case-control studies conducted in New Hampshire in 1994-1998 and in 1998-2001 (843 case patients and 1183 control subjects).Results: Regular and current cigarette smokers had higher risks of bladder cancer than never-smokers (for regular smokers, OR = 3.0, 95% CI = 2.4 to 3.6; for current smokers, OR = 5.2, 95% CI = 4.0 to 6.6). In New Hampshire, there was a statistically significant increasing trend in smoking-related bladder cancer risk over three consecutive periods (1994-1998, 1998-2001, and 2002-2004) among former smokers (OR = 1.4, 95% CI = 1.0 to 2.0; OR = 2.0, 95% CI = 1.4 to 2.9; and OR = 2.6, 95% CI = 1.7 to 4.0, respectively) and current smokers (OR = 2.9, 95% CI = 2.0 to 4.2; OR = 4.2, 95% CI = 2.8 to 6.3; OR = 5.5, 95% CI = 3.5 to 8.9, respectively) (P for homogeneity of trends over time periods = .04). We also observed that within categories of intensity, odds ratios increased approximately linearly with increasing pack-years smoked, but the slope of the increasing trend declined with increasing intensity.Conclusions: Smoking-related risks of bladder cancer appear to have increased in New Hampshire since the mid-1990s. Based on our modeling of pack-years and intensity, smoking fewer cigarettes over a long time appears more harmful than smoking more cigarettes over a shorter time, for equal total pack-years of cigarettes smoked.

- Abstract
The authors examined the relation between 45 common agricultural pesticides and prostate cancer incidence in a prospective cohort study of 55,332 male pesticide applicators from Iowa and North Carolina with no prior history of prostate cancer. Data were collected by means of self-administered questionnaires completed at enrollment (1993-1997). Cancer incidence was determined through population-based cancer registries from enrollment through December 31, 1999. A prostate cancer standardized incidence ratio was computed for the cohort. Odds ratios were computed for individual pesticides and for pesticide use patterns identified by means of factor analysis. A prostate cancer standardized incidence ratio of 1.14 (95% confidence interval: 1.05, 1.24) was observed for the Agricultural Health Study cohort. Use of chlorinated pesticides among applicators over 50 years of age and methyl bromide use were significantly associated with prostate cancer risk. Several other pesticides showed a significantly increased risk of prostate cancer among study subjects with a family history of prostate cancer but not among those with no family history. Important family history-pesticide interactions were observed. [ABSTRACT FROM AUTHOR]

Background: There is substantial epidemiological and experimental evidence that exposure to radon at levels found in underground mines can cause lung cancer. Although radon levels measured in homes are normally substantially lower, there is concern about the presence of a known lung carcinogen in a residential setting.Methods: Using national survey data on radon concentrations in homes in the former West Germany, the proportion and absolute numbers of lung cancer deaths attributable to radon are estimated. As lung cancer risk models derived directly from residential radon studies are not yet available, the risk model developed recently by Lubin et al. from a joint analysis of 11 underground miners' studies is applied. For an estimate of the impact of smoking on radon-attributable lung cancers, three different approaches are used and compared.Results: Our analysis shows that after adjusting for dosimetry differences between mines and homes about 7% of all lung cancer deaths in the western part of Germany may be due to residential radon. This corresponds to a total of about 2000 deaths (95% CI: 500-8200), 400 in females and 1600 in males. Adjusting for the intermediate relationship for smoking and radon, the attributable risk is estimated to be about 4-7% for smokers and 14-22% in non-smokers.Conclusions: Our analysis basically confirms the results of former calculations with regard to the total number of lung cancer deaths attributable to radon in West Germany. However, we show that the standard practice that applies the same model to smokers and non-smokers may result in biased estimates for these groups. [ABSTRACT FROM AUTHOR]- Published

The value of measuring three routine tests of liver function was assessed prospectively in 523 geriatric patients. Abnormalities were found in 27% of patients and were clinically helpful in half of these cases. Profiling liver function, without clinical indication, revealed abnormal results in 17% of patients and was important in one-third of these (6% of total). The two most important diagnoses were unsuspected osteomalacia and gall stone disease. [ABSTRACT FROM PUBLISHER]

Background: Several ecologic analyses have shown significant positive associations between mean indoor radon concentrations and risk of leukemia at all ages (acute myeloid leukemia and chronic lymphocytic leukemia) and for children (all leukemia, acute myeloid leukemia, and acute lymphoblastic leukemia [ALL]). As part of an age-matched, case-control study of childhood ALL in the United States, we investigated the association between the incidence of ALL in children under age 15 years and indoor radon exposure.Methods: Radon detectors were placed in current and previous homes of subjects where they resided for 6 months or longer. Children were included in analyses if radon measurements covered 70% or more of the 5-year period prior to diagnosis for case subjects (or from birth for case subjects under age 5 years) and the corresponding reference dates for control subjects. Radon levels could be estimated for 97% of the exposure period for the eligible 505 case subjects and 443 control subjects.Results: Mean radon concentration was lower for case subjects (65.4 becquerels per cubic meter [Bqm(-3)]) than for control subjects (79.1 Bqm(-3)). For categories less than 37, 37-73, 74-147, and 148 or more Bqm(-3) of radon exposure, relative risks based on matched case-control pairs were 1.00, 1.22, 0.82, and 1.02, respectively, and were similar to results from an unmatched analysis. There was no association between ALL and radon exposure within subgroups defined by categories of age, income, birth order, birth weight, sex, type of residence, magnetic field exposure, parental age at the subject's birth, parental occupation, or parental smoking habits.Conclusions: In contrast to prior ecologic studies, the results from this analytic study provide no evidence for an association between indoor radon exposure and childhood ALL.

The article presents a response to a commentary on a study that examined the association between mortality from lymphohematopoietic malignancies and brain cancer and work practices in the embalming industry. The family members and coworkers of deceased case and control embalmers from earlier surveys were interviewed to determine lifetime work histories and estimate exposure to formaldehyde. It is asserted that the proportional mortality ratios suggested in the commentary differ from the proportional mortality ratios in the authors' earlier surveys.
