E-Cigarette Marketing Regulations and Youth Vaping: Cross-Sectional Surveys, 2017–2019 David Hammond, Phd, Jessica L E-cigarette Marketing Regulations and Youth Vaping: Cross-Sectional Surveys, 2017–2019 David Hammond, PhD, Jessica L. Reid, MSc, Robin Burkhalter, MMath, Vicki L. Rynard, MSc BACKGROUND: Increased electronic cigarette (e-cigarette) use among young people is often abstract attributed to industry marketing practices; however, the effectiveness of regulations that limit e-cigarette advertising and promotions has yet to be examined. New federal legislation that liberalized the Canadian e-cigarette market in May 2018, along with differences in provincial regulations, provides an opportunity to examine the impact of regulatory restrictions on e-cigarette marketing. METHODS: Repeat cross-sectional surveys of 12 004 16- to 19-year-olds in Canada, completed online in 2017, 2018, and 2019. Logistic regression models were used to examine differences over time in exposure to e-cigarette marketing and e-cigarette use, including between provinces with differing strengths of marketing restrictions. RESULTS: The percentage of youth surveyed who reported noticing e-cigarette promotions often or very often approximately doubled between 2017 and 2019 (13.6% vs 26.0%; adjusted odds ratio [AOR] = 2.24, 95% confidence interval [CI] = 1.97–2.56). Overall exposure to marketing was generally more prevalent in provinces with fewer regulatory restrictions. Respondents who reported noticing marketing often or very often were more likely to report vaping in the past 30 days (AOR = 1.41, 95% CI = 1.23–1.62), past week (AOR = 1.44, 95% CI = 1.22–1.70), and $20 days in the past month (AOR = 1.42, 95% CI = 1.11–1.81, P = .005). Provinces with low restrictions on marketing had higher prevalence of vaping in the past 30 days (AOR = 1.50, 95% CI = 1.25–1.80, P , .001), and in the past week (AOR = 1.65, 95% CI = 1.33–2.05, P , .001). CONCLUSIONS: Exposure to marketing and the prevalence of vaping increased among Canadian youth after the liberalization of the e-cigarette market in 2018. Comprehensive provincial restrictions on e-cigarette marketing were associated with lower levels of exposure to marketing and lower prevalence of e-cigarette use.

  • Emerging Research on Potential Health Effects of Electronic Cigarettes Secondhand Exposure Flavorings
    Emerging Research on Potential Health Effects of Electronic Cigarettes The proposed Orange County Board of Health rule to prohibit use in enclosed areas of restaurants and bars is primarily concerned with preventing secondhand exposure and not with the role of e-cigarettes on smoking promotion vs. cessation. Therefore, the research cited below focuses on the chemical composition of e-liquids and aerosol, toxicology studies, the potential for secondhand exposure, and documented health effects. There are additional bodies of research on the effectiveness and safety of e-cigarettes for smoking cessation that are not listed here. The emerging body of research on e-cigarettes suggests that emitted aerosol may contain potentially harmful chemicals in addition to nicotine or other drugs. Secondhand Exposure Research demonstrates the potential for secondhand exposure to e-cigarette aerosol through biomarkers of nicotine exposure, as well as through studies done in controlled indoor conditions. Ballbé M, Martínez-Sánchez JM. (2014). Cigarettes vs. E-Cigarettes: Passive Exposure at Home Measured by Means of Airborne Marker and Biomarkers. Environmental Research. 135:76–80. This study showed that non-smokers passively exposed to e-cigarettes absorb nicotine. This study characterized passive exposure to nicotine from e-cigarette vapor and conventional cigarette smoke at home among non-smokers under real-use conditions. The airborne markers were statistically higher in conventional cigarette homes than in e-cigarettes homes (5.7 times higher). However, concentrations of both biomarkers among non- smokers exposed to conventional cigarette smoke and e-cigarette vapor were statistically similar (only 2 and 1.4 times higher, respectively).The levels of airborne nicotine and cotinine concentrations in the homes with e-cigarette users were statistically higher than control homes.

  • Vaping and E-Cigarettes: Adding Fuel to the Coronavirus Fire?
    Vaping and e-cigarettes: Adding fuel to the coronavirus fire? abcnews.go.com/Health/vaping-cigarettes-adding-fuel-coronavirus-fire/story By Dr. Chloë E. Nunneley 26 March 2020, 17:04 6 min read Vaping and e-cigarettes: Adding fuel to the coronavirus fire?Because vaping can cause dangerous lung and respiratory problems, experts say it makes sense that the habit could aggravate the symptoms of COVID-19. New data released by the Centers for Disease Control and Prevention last week warns that young people may be more impacted by COVID-19 than was initially thought, with patients under the age of 45 comprising more than a third of all cases, and one in five of those patients requiring hospitalization. Although scientists still don’t have good data to explain exactly why some young people are getting very sick from the novel coronavirus, some experts are now saying that the popularity of e-cigarettes and vaping could be making a bad situation even worse. Approximately one in four teens in the United States vapes or smokes e-cigarettes, with the FDA declaring the teenage use of these products a nationwide epidemic and the CDC warning about a life-threatening vaping illness called EVALI, or “E-cigarette or Vaping- Associated Lung Injury.” Public health experts believe that conventional cigarette smokers are likely to have more serious illness if they become infected with COVID-19, according to the World Health Organization. Because vaping can also cause dangerous lung and respiratory problems, 1/4 experts say it makes sense that the habit could aggravate the symptoms of COVID-19, although they will need longer-term studies to know for sure.

  • Why Do International Students Avoid Communicating with Americans?
    Journal of International Students, 7(3) 2017 Peer-Reviewed Article ISSN: 2162-3104 Print/ ISSN: 2166-3750 Online Volume 7, Issue 3 (2017), pp. 555-582 © Journal of International Students http://jistudents.org/ doi:10.5281/zenodo.570023 Why Do International Students Avoid Communicating with Americans? I-Ching Wang Teachers College, Columbia University, USA Janet N. Ahn William Paterson University, USA Hyojin J. Kim Teachers College, Columbia University, USA Xiaodong Lin-Siegler Teachers College, Columbia University, USA ABSTRACT We explore how the communication concerns of non-native English speakers (NNS) and Americans relate to their perceptions of each other and decisions to interact. NNS identified their concerns in communicating with Americans, the perceived causes of their concerns, and the strategies they would employ to address these concerns. Americans noted their perceptions of NNS’ (heavy and mild) accents and identified factors that influence their perceptions of NNS and decisions to communicate with NNS. Results revealed that the more NNS attribute their communication concerns to Americans’ bias, the more likely they would avoid interacting with Americans. Results also suggested that Americans show a more favorable attitude toward mild accent NNS. We discuss the implications these findings have for international education and future research. Keywords: communication, ESL, foreign accent, intercultural competence, perceived bias Over the past decade, the number of international students enrolling in higher education in America has been growing rapidly (Institute of International Education, 2015). Approximately 5 million international students are enrolled in American colleges and universities (OECD, 2015) and the number is projected to reach 8-10 million by the year 2020 (Forest, 2007; Phakiti, Hirsh & Woodrow, 2013).

  • Action Needed: E-Cigarettes
    ACTION NEEDED: E-CIGARETTES Since their introduction in 2008, e-cigarettes have become both ubiquitous and an increasing source of public policy concern and debate. This concern stems primarily from drastic increases in youth e-cigarette use. The most recent data show that 27.5% of high schoolers are using these products — a rate of youth tobacco product use not seen in nearly two decades. The public health community, parents and educators are shocked and worried to find their children and students using these products at home and even in class. Young people are reporting severe signs of dependence, E-cigarettes are now threatening including using e-cigarettes when they first wake up, inability to concentrate in the classroom without to undo all the progress that the using an e-cigarette, and even waking in the night public health community and to get a nicotine fix. government have made over decades We have known for decades that youth in particular to reduce cigarette smoking should not be exposed to nicotine because it changes brain chemistry to create a stronger addiction, can lead to memory and concentration Current generation of e-cigarettes problems, and can make youth who use it more susceptible to addiction to other substances. Research also suggests that young people who use e-cigarettes are four times more likely to go on to smoke combustible cigarettes. E-cigarettes are now threatening to undo all the progress that the public health community and JUUL government have made over decades to reduce cigarette smoking. Indeed, the surgeon general raised the alarm by issuing an advisory declaring a youth e-cigarette epidemic in December 2018.

  • Engineering and Delivery of Synthetic Chromatin Effectors
    Engineering and Delivery of Synthetic Chromatin Effectors by Stefan Josef Tekel A Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Approved March 2019 by the Graduate Supervisory Committee Karmella Haynes, Chair Michael Caplan Jeremy Mills David Brafman ARIZONA STATE UNIVERSITY May 2019 ABSTRACT Synthetic manipulation of chromatin dynamics has applications for medicine, agriculture, and biotechnology. However, progress in this area requires the identification of design rules for engineering chromatin systems. In this thesis, I discuss research that has elucidated the intrinsic properties of histone binding proteins (HBP), and apply this knowledge to engineer novel chromatin binding effectors. Results from the experiments described herein demonstrate that the histone binding domain from chromobox protein homolog 8 (CBX8) is portable and can be customized to alter its endogenous function. First, I developed an assay to identify engineered fusion proteins that bind histone post translational modifications (PTMs) in vitro and regulate genes near the same histone PTMs in living cells. This assay will be useful for assaying the function of synthetic histone PTM-binding actuators and probes. Next, I investigated the activity of a novel, dual histone PTM binding domain regulator called Pc2TF. I characterized Pc2TF in vitro and in cells and show it has enhanced binding and transcriptional activation compared to a single binding domain fusion called Polycomb Transcription Factor (PcTF). These results indicate that valency can be used to tune the activity of synthetic histone-binding transcriptional regulators. Then, I report the delivery of PcTF fused to a cell penetrating peptide (CPP) TAT, called CP-PcTF.
