RESUMO
INTRODUCTION: In the United States, electronic cigarettes (e-cigarettes) are currently unregulated, extensively marketed, and experiencing a rapid increase in use. The purpose of this study was to examine the opinions of U.S. adults about e-cigarette use in smoke-free public areas. METHODS: Data were obtained from the online HealthStyle survey administered to a probability sample of a nationally representative online panel. The study included 4,043U.S. adults, aged 18 years or older who responded to this question, "Do you think e-cigarette should be allowed to be used in public areas where tobacco smoking is prohibited?" Multinomial logistic regression analyses were used to examine opinions on e-cigarette use in smoke-free areas by sex, age, race/ethnicity, household income, education, census region, and cigarette smoking status and e-cigarette awareness and ever use. RESULTS: Overall, about 40% of adults were uncertain whether e-cigarettes should be allowed in smoke-free areas, 37% opposed, while 23% favored their use in smoke-free public places. Multinomial logistic regression analyses showed that adults who were aware, ever used e-cigarettes, and current cigarette smokers were more likely to express an "in favor" opinion than adults who expressed an uncertain opinion (don't know). CONCLUSION: Over 75% of U.S. adults reported uncertainty or disapproval of the use of e-cigarettes in smoke-free areas. Current cigarette smokers, adults aware or have ever used e-cigarettes were more supportive to exempting e-cigarettes from smoking restrictions. With impending regulation and the changing e-cigarette landscape, continued monitoring and research on public opinions about e-cigarette use in smoke-free places are needed.

INTRODUCTION: The purpose of this study is to examine the change in smoking policy status among Georgia restaurants and bars from 2006 to 2012 and to identify restaurant and bar characteristics that are associated with allowing smoking. METHODS: Data were obtained from similar cross-sectional indoor air surveys conducted in 2006 and 2012 in Georgia. Both surveys were designed to gather information about restaurant and bar smoking policies. Weighted χ(2) analyses were performed to identify changes in smoking policy status and other variables from 2006 to 2012. Weighted logistic regression analysis was used to test for significant associations between an establishment's smoking policy and other characteristics. RESULTS: The percentage of restaurants and bars in Georgia that allowed smoking nearly doubled, from 9.1% in 2006 to 17.6% in 2012. The analyses also showed a significant increase in the percentage of establishments that allow smoking when minors are present. Having a liquor license was a significant predictor of allowing smoking. CONCLUSION: The Smokefree Air Act was enacted in 2005 to protect the health and welfare of Georgia citizens, but study results suggest that policy makers should reevaluate the law and consider strengthening it to make restaurants and bars 100% smokefree without exemptions.

INTRODUCTION: This study examined reasons why people planned to reduce or stop tobacco consumption and their relationship with MPOWER scores, adjusting for sociodemographic, cultural, and economic factors. METHODS: Data used were Euromonitor International's Voice of the Consumer: Nicotine Survey 2019-2020, World Bank's country income and WHO's MPOWER policy scores. Analytical sample included 21913 adults of legal smoking age in 21 middle- and high-income countries who used nicotine and tobacco products and planned to reduce or stop their consumption in the next 12 months. Poisson regression models with robust error variance, adjusted for sociodemographic and tobacco use covariables, generated adjusted risk ratios (ARRs) of selecting a certain reason to reduce tobacco consumption dependent on continuous MPOWER scores. RESULTS: Main reasons to reduce or stop tobacco consumption were improving health (85%), saving money (65%), pressure from family (19%), and using another substance instead (4%). Country variation was observed by MPOWER scores. Positive associations were found between some MPOWER scores and reasons to reduce or stop tobacco consumption: enforcing bans on tobacco advertising and using another substance (ARR=1.28; 95% CI: 1.11-1.47); warning about dangers of tobacco and saving money (ARR=1.25; 95% CI: 1.19-1.32); offering help to quit tobacco and using another substance (ARR=1.26; 95% CI: 1.10-1.45) or family pressure (ARR=1.11; 95% CI: 1.04-1.17); anti-tobacco campaigns and using another substance (ARR=1.15; 95% CI: 1.08-1.23); and raising taxes and saving money (ARR=1.11; 95% CI: 1.09-1.13). CONCLUSIONS: MPOWER scores are associated with reported reasons to quit tobacco including to improve health, save money, respond to family pressure or use another substance instead.
RESUMO
INTRODUCTION: Although the impact of long-term use of electronic cigarettes (e-cigarettes) on health is still unknown, current scientific evidence indicates that e-cigarettes are less harmful than combustible cigarettes. The study examined whether perceived relative harm of e-cigarettes and perceived addictiveness have changed during 2012-2015 among U.S. adults. METHODS: Data were from Tobacco Products and Risk Perceptions surveys of probability samples representative of U.S. adults in 2012, 2014, and 2015. Changes over time in perceived harmfulness of e-cigarettes were examined using pairwise comparisons of proportions and multinomial logistic regression analysis. Analyses were conducted in January 2016. RESULTS: Whereas 11.5% and 1.3% of adults perceived e-cigarettes to have about the same level of harm and to be more harmful than cigarettes, respectively, in 2012, 35.7% and 4.1% did so in 2015. The proportion of adults who thought e-cigarettes were addictive more than doubled during 2012-2015 (32.0% in 2012 vs 67.6% in 2015). Compared with 2012, the odds of perceiving e-cigarettes to be equally or more harmful (than to be less harmful) doubled (95% CI=1.64, 2.41) in 2014, and tripled (95% CI=2.60, 3.81) in 2015. CONCLUSIONS: There is an increase in the proportion of U.S. adults who misperceive the harm of e-cigarettes and consider them to be as harmful as combustible cigarettes. The study highlights the need to design public health messages that accurately interpret the scientific data on the potential harm of e-cigarettes and clearly differentiate the absolute from the relative harm of e-cigarettes.

Synergistic interactions between cytokines, chemokines and adhesion molecules may facilitate the selective recruitment of eosinophils into sites of allergic inflammation. Ovalbumin-sensitized IL5TG mice responded to antigen challenge with robust airway eosinophilia 24 and 72 hr post-exposure. Adhesion molecule expression and functional responsiveness of immune cells derived from IL5TG mice to various inflammatory mediators were evaluated. IL5TG-derived eosinophils, but not neutrophils, expressed higher levels of CD49d and CD11b relative to WT. Functional responsiveness to eotaxin was increased in IL5TG eosinophils as demonstrated by a 10x increase in its potency in producing actin polymerization and 3x increase in CD11b upregulation relative to WT. These data are consistent with increased CCR3 expression on IL5TG eosinophils. Responsiveness of eosinophils to LTB4 or MIP-1alpha was similar between WT and IL-5TG mice. These data provide evidence of synergy between eosinophil-specific cytokines and chemokines that may promote accumulation of this cell type under conditions of allergic inflammation in vivo.
