AbstractBackground:. The current e-cigarette market has been rapidly evolving with an increase in the share of high nicotine concentration vaping products. This study examined urinary biomarkers of exposure (BOE) by nicotine concentration level among exclusive e-cigarette users.Methods:. Data were drawn from wave 5 (December 2018–November 2019) of the Population Assessment of Tobacco and Health study. Between-subject differences in BOEs of nicotine, metal, tobacco-specific nitrosamine, and volatile organic compounds were examined across e-cigarettes containing nicotine or not [yes (n = 300) vs. no (n = 31) vs. non-tobacco use (n = 3,021)] and different nicotine concentration levels (0.1%–1.7%, 1.8%–4.9%, and 5.0%+).Results:. Among 3,353 participants, exclusive e-cigarette users exhibited higher mean concentrations of nicotine metabolites than non-tobacco users. Nicotine e-cigarette users had higher concentrations of total nicotine equivalents-2 [TNE2; mean (95% confidence interval), 21

AbstractBackground:. Scanning with low-dose computed tomography reduces lung cancer mortality by 20% among high-risk individuals. Despite its efficacy, the uptake of lung cancer screening (LCS) remains low. Our study aimed to estimate state-level and nationwide LCS rates among eligible individuals and to assess disparities in LCS uptake.Methods:. Data for this study were obtained from the 2022 Behavioral Risk Factor Surveillance System. Multivariable logistic regression models were used to model the associations between predictors and outcome variables and to examine LCS variability across states.Results:. Of the 28,071 participants eligible for LCS, 17.24% underwent LCS. Participants ages 65 to 79 years were [OR, 1.75; 95% confidence interval (CI), 1.54–1.99] more likely to undergo LCS than their younger counterparts. Those who were female (OR, 0.83; 95% CI, 0.73–0.94); divorced, separated, or widowed (OR, 0.85; 95% CI, 0.74–0.98); without health insurance (OR, 0.34; 95% CI, 0.22–0.53

Abstract. The risk of gastric cancer among immigrants from countries where Helicobacter pylori is endemic greatly exceeds those born in the United States. Among patients in the Los Angeles safety-net health system, the risk of advanced and fatal gastric cancer is higher in Hispanic versus non-Hispanic patients. There is an urgent need to define whether this reflects concomitant illnesses, such as metabolic disease, occupational exposures, or differential access to H. pylori eradication and endoscopic gastric cancer screening programs.See related article by Klingbeil et al., p. 75
