Abstract
BACKGROUND: Electronic nicotine delivery systems (ENDS), also referred to as electronic cigarettes or e-cigarettes, were introduced into the US market in 2007. Despite concerns regarding the long-term health impact of this product, there is little known about awareness and use of ENDS among adults in the USA. METHODS: A consumer-based mail-in survey (ConsumerStyles) was completed by 10,587 adults (>/= 18 years) in 2009 and 10,328 adults in 2010. Data from these surveys were used to monitor awareness, ever use and past month use of ENDS from 2009 to 2010 and to assess demographic characteristics and tobacco use of ENDS users. RESULTS: In this US sample, awareness of ENDS doubled from 16.4% in 2009 to 32.2% in 2010 and ever use more than quadrupled from 2009 (0.6%) to 2010 (2.7%). Ever use of ENDS was most common among women and those with lower education, although these were not the groups who had heard of ENDS most often. Current smokers and tobacco users were most likely to try ENDS. However, current smokers who had tried ENDS did not say they planned to quit smoking more often than smokers who had never tried them. CONCLUSIONS: Given the large increase in awareness and ever use of ENDS during this 1-year period and the unknown impact of ENDS use on cigarette smoking behaviours and long-term health, continued monitoring of these products is needed.

Abstract
BACKGROUND: Mexican smokers are more likely to be non-daily smokers and to consume fewer cigarettes per day than smokers in other countries. Little is known about their quit behaviors. AIM: The aim of this study is to determine factors associated with having made a quit attempt and being successfully quit at 14-month follow-up in a population-based cohort of adult Mexicans who smoke at different levels of intensity. DESIGN: A longitudinal analysis of wave-III and wave-IV (2010) Mexican administration of International Tobacco Control Policy Evaluation Project was conducted. SETTING: This study was conducted in six large urban centers in Mexico PARTICIPANTS: The participants of this study comprised 1206 adults who were current smokers at wave-III and who were followed to wave-IV. MEASUREMENTS: We compared three groups of smokers: non-daily smokers-who did not smoke every day in the past 30 days (n=398), daily light smokers who smoked every day at a rate of 5 cigarettes per day (n=434). Data on smoking behavior, psychosocial characteristics and socio-demographics were collected at baseline and after 14 months. FINDINGS: In multivariate logistic regression predicting having made a quit attempt at follow-up, significant factors included being a non-daily smoker versus a heavy daily smoker (ORadj=1.83, 95% CI: 1.19-2.83), less perceived addiction (ORadj=1.86, 95% CI: 1.20-2.87), greater worry that cigarettes will damage health (ORadj=2.04, 95% CI: 1.16-3.61) and having made a quit attempt in the past year at baseline (ORadj=1.70, 95% CI: 1.23-2.36). In multivariate logistic regression predicting being successfully quit at one-year follow-up, significant factors included being a non-daily smoker versus a heavy daily smoker (ORadj=2.54, 95% CI: 1.37-4.70) and less perceived addiction (not addicted: ORadj=3.26, 95% CI: 1.73-6.14; not much: ORadj=1.95, 95% CI: 1.05-3.62 versus very much). CONCLUSIONS: Mexican adult smokers who are non-daily smokers were more likely than daily heavy smokers to have attempted to quit during follow-up and to succeed in their quit attempt. Future research should determine whether tobacco control policies and programs potentiate this tendency and which interventions are needed to help heavier smokers to quit.

Abstract
BACKGROUND/AIMS: Long-term cigarette smoking (CS) is a major risk factor for respiratory and cardiovascular diseases, and is also known to adversely affect other organs. However, data on the systemic effects of short-term CS exposure (STCSE) are scarce. Presently, using a nose-only exposure system, we evaluated the systemic effects of STCSE in mice. METHODS: We assessed the effects of CS generated by 9 consecutive cigarettes per day for 4 days in a nose-only exposure system on cardiovascular, hepatic and renal endpoints evaluated on day 5 in mice. Control mice were exposed to air only. RESULTS: CS significantly increased systolic blood pressure and decreased total nitric oxide plasma concentration. Circulating platelets and erythrocyte numbers were also increased. However, STCSE did not significantly increase thrombosis in pial arterioles and venules. STCSE significantly raised plasma alanine aminotransferase and gamma glutamyl transpeptidase activities, but did not affect urea or creatinine concentrations. Interestingly, while STCSE enhanced the production of reactive oxygen species in heart and kidney and lipid peroxidation in heart, liver and kidneys, it also enhanced the antioxidant activity of superoxide dismutase, probably indicating that STCSE causes adaptive reactions to counterbalance the potentially damaging action of oxygen radicals induced by STCSE. CONCLUSION: These results suggest that STCSE causes blood pressure increase, hepatotoxicity and oxidative stress in the heart, liver and the kidneys. These data provide information on the initial steps leading to the systemic effects of STCSE, a stage at which the diseases may likely be reversed.

Abstract
BACKGROUND: The emergence of hookah is being noted on college campuses and in large U.S. cities and evidence points to an increasing trend for college students. The purpose of this study was to assess hookah use and identify associations with cigarette smoking and demographic factors. METHODS: An intercept sampling method was used at various locations on a large university campus in the southeastern United States, yielding a high participation rate (52%). A total of 1,203 participants completed a computer-aided survey that assessed the use of tobacco products. The sample characteristics were then weighted to match the University population of students enrolled during the same semester. Bivariate (chi-square and t-test) and multivariate (logistic regression) tests of association were conducted to assess differences between cigarette and hookah users. RESULTS: Hookah smoking exceeded cigarette smoking for both ever use (46.4% vs 42.1%) and past year use (28.4% vs 19.6%). Females and males used hookah at similar rates. Hispanic respondents had the highest prevalence of current use of hookah (18.9%) and cigarettes (16.4%). CONCLUSIONS: As hookah surpasses cigarette use, efforts need to be made to slow the increase in new tobacco products that are attractive to young adults and that pose many of the same health risks as those related to traditional tobacco products. Prevalence of all emerging tobacco products, including hookah, and the relationship with cigarette use needs to be monitored on an ongoing basis.

Abstract
The aim of the present work was to optimize a preparation step for polycyclic aromatic hydrocarbons in a fatty extract. Solid-phase microextraction is an easy preparation technique, which allows to minimize solvent consumption and reduce sample manipulation. A Carbopack Z/polydimethylsiloxane fiber, particularly suitable for extraction of planar compounds, was employed to extract polycyclic aromatic hydrocarbons from a hexane solution obtained after a previous extraction with acetonitrile from oil, followed by a liquid-liquid partition between acetonitrile and hexane. The proposed method was a rapid and sensitive solution to reduce the interference of triglycerides saving the column life and avoiding frequent cleaning of the mass spectrometer ion source. Despite the non-quantitative extraction of polycyclic aromatic hydrocarbons from oil using acetonitrile, the signal-to-noise ratio was significantly improved obtaining a limit of detection largely below the performance criteria required by the European Union legislation.

Abstract
BACKGROUND: Smoking tobacco is one of the most preventable causes of illness and death. Web-based tailored smoking cessation interventions have shown to be effective. Although these interventions have the potential to reach a large number of smokers, they often face high attrition rates, especially among lower educated smokers. A possible reason for the high attrition rates in the latter group is that computer-tailored smoking cessation interventions may not be attractive enough as they are mainly text-based. Video-based messages might be more effective in attracting attention and stimulating comprehension in people with a lower educational level and could therefore reduce attrition rates. OBJECTIVE: The objective of the present study was to investigate whether differences exist in message-processing mechanisms (attention, comprehension, self-reference, appreciation, processing) and future adherence (intention to visit/use the website again, recommend the website to others), according to delivery strategy (video or text based messages) and educational level, to a Dutch computer-tailored smoking cessation program. METHODS: Smokers who were motivated to quit within the following 6 months and who were aged over 16 were included in the program. Participants were randomly assigned to one of two conditions (video/text CT). The sample was stratified into 2 categories: lower and higher educated participants. In total, 139 participants completed the first session of the web-based tailored intervention and were subsequently asked to fill out a questionnaire assessing message-processing mechanisms and future adherence. ANOVAs and regression analyses were conducted to investigate the differences in message-processing mechanisms and future adherence with regard to delivery strategy and education. RESULTS: No interaction effects were found between delivery strategy (video vs text) and educational level on message-processing mechanisms and future adherence. Delivery strategy had no effect on future adherence and processing mechanisms. However, in both groups results indicated that lower educated participants showed higher attention (F(1,138)=3.97; P=.05) and processing levels (F(1,138)=4.58; P=.04). Results revealed also that lower educated participants were more inclined to visit the computer-tailored intervention website again (F(1,138)=4.43; P=.04). CONCLUSIONS: Computer-tailored programs have the potential to positively influence lower educated groups as they might be more involved in the computer-tailored intervention than higher educated smokers. Longitudinal studies with a larger sample are needed to gain more insight into the role of delivery strategy in tailored information and to investigate whether the intention to visit the intervention website again results in the ultimate goal of behavior change.

Abstract
This study was conducted during February-March 2012 to determine the perception and support regarding smoke-free policy among tourists at Suvarnabhumi International Airport, Bangkok, Thailand. In this cross-sectional study, 200 tourists (n = 200) were enrolled by convenience sampling and interviewed by structured questionnaire. Descriptive statistics, chi-square, and multinomial logistic regression were adopted in the study. Results revealed that half (50%) of the tourists were current smokers and 55% had visited Thailand twice or more. Three quarter (76%) of tourists indicated that they would visit Thailand again even if it had a 100% smoke-free regulation. Almost all (99%) of the tourists had supported for the smoke-free policy (partial ban and total ban), and current smokers had higher percentage of support than non-smokers. Two factors, current smoking status and knowledge level, were significantly associated with perception level. After analysis with Multinomial Logistic Regression, it was found that perception, country group, and presence of designated smoking room (DSR) were associated with smoke-free policy. Recommendation is that, at institution level effective monitoring system is needed at the airport. At policy level, the recommendation is that effective comprehensive policy needed to be emphasized to ensure smoke-free airport environment.

Abstract
BACKGROUND: The sale of smokeless tobacco has been totally banned in Finland since the country joined the European Union in 1995. Adolescents have continued to use smokeless tobacco even after the sales ban. The objective was to describe dual use of Swedish snuff (snus) and cigarettes in young adults living in Northern Finland. METHODS: This study on male military recruits (n = 1151, mean age 19.4 years; response rate 80%) investigated association of snus use with self-reported tobacco use, nicotine dependence and attempts to quit smoking. RESULTS: Overall, 15.6% (n = 179) reported daily snus use, and almost half of them were dual users who used both products, i.e. cigarettes and snus, daily. Daily smokers were often occasional snus users (66.3%), and those with dual use smoked equal number of cigarettes per day as daily smokers who were not snus users. In addition, dual snus use seemed to increase the dependence to cigarettes, although this trend did not reach statistical significance. Dual users tried to quit less likely than exclusive smokers. Very few snus users were 'switchers' (ex-smokers) [3.2% (n = 22) of all snus users]. CONCLUSIONS: Dual use of snus and cigarettes is common among young in Finland, despite the sales ban on snus. The role of snus in reducing cigarette smoking is unclear, but it is likely that snus use complicates the attempts to quit smoking.

Abstract
Two micro-extraction methods, air-agitated liquid-liquid microextraction (AALLME) and dispersive liquid-liquid microextraction (DLLME), have been compared with each other by applying them for the analysis of five triazole pesticides (penconazole, hexaconazole, diniconazole, tebuconazole and triticonazole) in aqueous samples by gas chromatography with flame ionization detection (GC-FID). In the AALLME method, which excludes any disperser solvent, much less volume of organic solvent is used. In order to form fine and dispersed organic droplets in the aqueous phase, the mixture of aqueous sample solution and extraction solvent is repeatedly aspirated and dispensed with a syringe. In the DLLME method, an appropriate mixture of extraction solvent and disperser solvent is rapidly injected by a syringe into the aqueous sample. Effect of the pertinent experimental factors on DLLME (i.e. identity and volume of the extraction and disperser solvents and ionic strength) and on AALLME (identity and volume of the extraction solvent, number of agitations, and ionic strength) were investigated. Under optimal conditions, limits of detection for the five target pesticides obtained by AALLME-GC-FID and DLLME-GC-FID ranged from 0.20 to 1.1ngmL(-1) and 1.9 to 5.9ngmL(-1), respectively. The relative standard deviations (RSDs, n=5) were in the range of 1-4% and 3-5% with the enrichment factors of 449-504 and 79-143 for AALLME-GC-FID and DLLME-GC-FID, respectively. Both of the compared methods are simple, fast, efficient, inexpensive and can be applied to the analysis of the five pesticides in different aqueous samples in which penconazole and hexaconazole were found. For spiked samples, the recoveries were in the ranges of 92-105%, and 92-104% for AALLME and DLLME, respectively.

Abstract
BACKGROUND: Populations at risk for esophageal adenocarcinoma remain poorly defined. Laryngeal symptoms can be secondary to laryngopharyngeal reflux (LPR) and can occur without associated gastroesophageal reflux symptoms such as heartburn and regurgitation. GOAL: We sought to determine the prevalence of Barrett esophagus (BE) in otolaryngology patients with laryngeal symptoms+/-typical gastroesophageal reflux disease (GERD) symptoms. STUDY: We performed a cross-sectional study of otolaryngology clinic patients who reported laryngeal symptoms. Symptoms, medications, and exposure histories were obtained. Unsedated transnasal endoscopy was performed. Suspected BE was biopsied and confirmed histologically. Risk factors and prevalence of BE were assessed. RESULTS: Two hundred ninety-five patients were enrolled [73% male, median age 60 y (interquartile range 51 to 68 y)]. The overall prevalence of BE was 11.8% (n=33). Antisecretory medication use was present in 56% (n=156) of patients at enrollment. Compared with patients without BE, patients with BE were more likely to be male (P=0.01) and to report occupational lung injury (P=0.001). Duration, but not severity of laryngeal symptoms, significantly increased the odds of BE (odds ratio, 5.64; 95% confidence interval, 1.28-24.83; for a duration of symptoms >5 y). Of patients with BE, 58% (n=19) had coexisting LPR and GERD symptoms and 30% (n=10) had only LPR symptoms. Presence and size of hiatal hernia and length of columnar-lined esophagus were significant risk factors for BE. CONCLUSIONS: Long-standing laryngeal symptoms are associated with the presence of BE in otolaryngology patients. Patients with chronic laryngeal symptoms and no identifiable ear, nose, or throat etiology for those symptoms may benefit from endoscopic screening regardless of whether typical GERD symptoms are present.
