Exposure to volatile organic compounds and chronic respiratory disease mortality, a case-cohort study.

Background: Chronic respiratory diseases (CRDs) are the third leading cause of death worldwide. Data of the associations between specific volatile organic compounds (VOCs), a major component of air pollution and tobacco smoke, and subsequent CRD mortality in the general population are scarce.

Methods: In a case-cohort analysis within the population-based Golestan cohort study (n = 50045, aged 40-75 years, 58% women, enrollment: 2004-2008, northeastern Iran), we included all participants who died from CRD during follow-up through 2018 (n = 242) as cases and stratified them into 16 strata defined by age, sex, residence, and tobacco smoking.

Impact of screening for HPV-positive oropharyngeal cancers: a microsimulation-based modeling study.

Background: We estimated the impact of screening on morbidity and mortality of HPV16-positive oropharyngeal cancer among US men aged 45-79 years.

Methods: We developed an individual-level, state-transition natural history microsimulation model to estimate the impact of screening using oral HPV16 detection, HPV16-E6 antibody detection, and transcervical-ultrasound of neck/oropharynx. We compared clinical detection to counterfactual screen detection for cancer stage, single- vs multiple-modality treatment, and survival.

Data-integration with pseudoweights and survey-calibration: application to developing US-representative lung cancer risk models for use in screening.

Accurate cancer risk estimation is crucial to clinical decision-making, such as identifying high-risk people for screening. However, most existing cancer risk models incorporate data from epidemiologic studies, which usually cannot represent the target population. While population-based health surveys are ideal for making inference to the target population, they typically do not collect time-to-cancer incidence data.

Racial/ethnic differences in trends of testicular germ cell tumor incidence in the United States, 1992-2021.

Background: Testicular germ cell tumors (TGCTs) are the most common cancers among young men in the United States. Incidence rates among non-Hispanic White (NHW) men historically have been much higher than the rates among other men. To study whether this pattern had changed, the authors examined trends in TGCT incidence for the years 1992-2021.
