2013 Selected Scientific Accomplishments

The most recent Surgeon General’s report, “Preventing Tobacco Use Among Youth and Young Adults”, published in 2012, contained the following causal statement about movie smoking: “The evidence is sufficient to conclude that there is a causal relationship between depictions of smoking in the movies and initiation of smoking among young people.” NCCC Cancer Control researchers made major contributions to the science underlying that statement. Youths with high movie exposure were, on average, twice as likely to smoke.

Our cohort studies for US adolescent exposure to smoking in movies was explored regarding effect modification by race/ethnicity, with Black adolescents found to be less responsive to movie smoking and movie alcohol compared to Whites (Dal Cin, Stoolmiller, & Sargent, 2013). This national cohort also has supported studies of the association between alcohol-branded merchandise and youth drinking (McClure, Stoolmiller, Tanski, Engels, & Sargent, 2013).

Working with colleagues in the Department of Chemistry, Cancer Control Members (Tanski) developed a nanotechnology nicotine-sensing film comprising the conductive polymer polyaniline linked with a reporting layer, recording changes in chemiresistance due to adsorption of nicotine. Experiments were carried out in a microprocessor-controlled smoking chamber calibrated for total suspended particle, carbon monoxide, and nicotine concentrations. We found significant real-time increases in the resistance of films upon exposure to SHS. The sensors were shown to be sensitive to the number of cigarettes consumed in the chamber and ambient nicotine and demonstrated reasonable recovery between measurements. The sensors have sufficient sensitivity to detect off-gassing of nicotine or "thirdhand smoke."(Liu, Antwi-Boampong, Belbruno, Crane, & Tanski, 2013). Development of integrated personal sensors to record exposure to SHS using this technology currently is underway, which will lead to larger projects for using the device to measure secondhand smoke exposure and how often smokers use combustible tobacco.

The New Hampshire Colonoscopy Registry database (Butterly) includes almost 9,000 patients with serrated polyps at baseline colonoscopy. Consent rates are uniformly high (80%), using an informed consent that grants permission for future contact. By December 2013, the NHCR will have enrolled nearly 83,000 patients. The NHCR has reported on significantly higher ADR in surveillance than in screening colonoscopies,(J. C. Anderson, Butterly, Goodrich, Robinson, & Weiss, 2013, In press). A subgroup of left-colon adenomas in heavy smokers exhibited a methylation profile similar to right-colon adenomas (Koestler et al., 2013). NHCR Site and ADR feedback reports regularly sent to endoscopists revealed wide variation of ADRs and other quality indicators (J. C. Anderson et al., 2013, In press).

A 2013 Dartmouth Atlas Report on trends in end of life cancer care compared 2003 to 2007 results with deaths occurring in 2010. While an absolute reduction of 4% occurred for in-hospital deaths, the report revealed that many Medicare beneficiaries receive Hospice care only within a few days of death.

Follow up studies of decision support in palliative care included qualitative studies of how patients (Maloney et al., 2013) and oncologists (Bakitas, Lyons, Hegel, & Ahles, 2012) perceived the intervention, demonstrating support of programs that integrate palliative care with oncology care at the start of therapy.

  • Longacre, Beach, Adachi-Mejia, and Dalton found that exposure to movie smoking during early adolescence was a more important predictor of young adult smoking than exposure during late adolescence (Primack, 2012).

  • Sargent and colleagues disaggregated exposure by motion picture rating and found that doseresponse for PG-13 exposure was similar to that of R-rated movie smoking, suggesting that the movie smoking--youth smoking association is specific to movie smoking, not confounded by unmeasured personality factors that draw high-risk adolescents to movies that tend to show risk behaviors (Stoolmiller, 2012). This study included a translational and policy-relevant estimate of the percentage that youth smoking would be reduced if PG-13 smoking were eliminated—equivalent to an R-rating for smoking (i.e., 18%).
