Adding selegiline to nicotine patch was associated with a doubling of the 52-week continuous abstinence rate, but this difference was not statistically significant. Selegiline significantly reduced craving for cigarettes and appeared to mitigate the need for nicotine replacement therapy. The results suggest that selegiline is a promising drug for future smoking cessation research.
Alpha track radon detectors were placed in the homes of 35 lung cancer patients and 35 matched controls for a period of 8 to 10 mo. Twenty lung cancer patients had small cell lung carcinoma; 11 had adenocarcinoma, 2 had squamous cell carcinoma, and 2 had unclassified carcinoma among 15 nonsmokers. Mean overall living on ground level was significantly higher in the group with small cell lung carcinoma (50 y +/- 15) than among controls (33 y +/- 19); the adjusted odds ratio for lung cancer was 5.2 (90% confidence interval [90% CI] = 1.1-24.9) per decade of living on the ground floor for the group with small cell lung carcinoma. Radon exposure of more than 1.0 pci/l in the group with small cell lung carcinoma was associated with increased risk of lung cancer, although it did not reach statistical significance [odds ratio = 1.5 (90% CI = 0.4-5.4)], adjusting for differences in smoking habits. Our study supports the presence of a differentially increased risk for small cell lung carcinoma following long-term radon exposure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
