Abstract
A mechanically hard and cohesive porous fiber, with large surface area, for more strong attachment of the coating was provided by platinizing a stainless steel wire. Then, the platinized stainless steel fiber was coated with a multiwalled carbon nanotube/polyaniline (MWCNT/PANI) nanocomposite using electrophoretic deposition (EPD) method and applied for the extraction of thymol and carvacrol with direct-immersion solid-phase microextraction (DI-SPME) method followed by high-performance liquid chromatography-ultraviolet detection (HPLC-UV) quantification. To provide a larger coarse surface for the tightened attachment of coating on the fiber, a stainless steel wire was platinized using a suitable optimized EPD method. Different experimental parameters were studied and the optimal conditions were obtained as: pH of the sample solution: 2; extraction time: 60min; salt content in the sample solution: 1% w/v NaNO3; desorption time: 60min; type and volume of the desorption solvent: acetonitrile, 100muL. Under the optimized conditions, limits of detection (LODs) were 0.6 and 0.8mugmL(-1) for thymol and carvacrol, respectively. Linear dynamic range (LDR) for the calibration curves of both analytes were 1-80mugmL(-1). Relative standard deviation (RSD%, n=6) was 6.8 for thymol and 12.7 for carvacrol. The proposed fiber was successfully applied for the recovery and determination of thymol and carvacrol in thyme, savory, and honey samples.

Abstract
The asymmetric unit of the title compound, C15H13N3O3.H2O, comprises a 4-{(E)-[2-(pyridin-4-ylcarbon-yl)hydrazinyl-idene]meth-yl}phenyl acetate mol-ecule and a solvent water mol-ecule linked by O-Hcdots, three dots, centeredO and O-Hcdots, three dots, centeredN hydrogen bonds from the water mol-ecule and a C-Hcdots, three dots, centeredO contact from the organic mol-ecule. The compound adopts an E conformation with respect to the azomethine bond and the dihedral angle between the pyridine and benzene rings is 21.90 (7) degrees . The azomethine bond [1.275 (2) A] distance is very close to the formal C=N bond length, which confirms the azomethine bond formation. An extensive set of O-Hcdots, three dots, centeredO, O-Hcdots, three dots, centeredN, N-Hcdots, three dots, centeredO and C-Hcdots, three dots, centeredO hydrogen bonds builds a two-dimensional network progressing along the c axis.

Abstract
OBJECTIVE: To assess dependence levels in users of e-cigarettes, and compare them with dependence levels in users of nicotine gums and tobacco cigarettes. DESIGN: Self-reports from cross-sectional Internet and mail surveys. Comparisons of: (a) 766 daily users of nicotine-containing e-cigarettes with 30 daily users of nicotine-free e-cigarettes; (b) 911 former smokers who used the e-cigarette daily with 451 former smokers who used the nicotine gum daily (but no e-cigarette); (c) 125 daily e-cigarette users who smoked daily (dual users) with two samples of daily smokers who did not use e-cigarettes (2206 enrolled on the Internet and 292 enrolled by mail from the general population of Geneva). We used the Fagerstrom test for nicotine dependence, the nicotine dependence syndrome scale, the cigarette dependence scale and versions of these scales adapted for e-cigarettes and nicotine gums. RESULTS: Dependence ratings were slightly higher in users of nicotine-containing e-cigarettes than in users of nicotine-free e-cigarettes. In former smokers, long-term (>3 months) users of e-cigarettes were less dependent on e-cigarettes than long-term users of the nicotine gum were dependent on the gum. There were few differences in dependence ratings between short-term (=3 months) users of gums or e-cigarettes. Dependence on e-cigarettes was generally lower in dual users than dependence on tobacco cigarettes in the two other samples of daily smokers. CONCLUSIONS: Some e-cigarette users were dependent on nicotine-containing e-cigarettes, but these products were less addictive than tobacco cigarettes. E-cigarettes may be as or less addictive than nicotine gums, which themselves are not very addictive.

Abstract
INTRODUCTION: There is anecdotal evidence that health messages interpreted from waterpipe tobacco smoking (WTS) research are inconsistent, such as comparing the health effects of one WTS session with that of 100 cigarettes. This study aimed to identify key health themes about WTS discussed by online news media, and how numerical cigarette-waterpipe equivalence (CWE) was being interpreted. METHODS: We identified 1065 online news articles published between March 2011 and September 2012 using the 'Google Alerts' service. We screened for health themes, assessed statements mentioning CWE and reported differences between countries. We used logistic regression to identify factors associated with articles incorrectly reporting a CWE equal to or greater than 100 cigarettes, in the absence of any comparative parameter ('CWE >/=100 cigarettes'). RESULTS: Commonly mentioned health themes were the presence of tobacco (67%) and being as bad as cigarettes (49%), and we report on differences between countries. While 10.8% of all news articles contained at least one positive health theme, 22.9% contained a statement about a CWE. Most of these (18.6% total) were incorrectly a CWE >/=100 cigarettes, a quarter of which were made by healthcare professionals/organisations. Compared with the Middle East, articles from the USA and the UK were the most significant predictors to contain a CWE >/=100 cigarettes statement. CONCLUSIONS: Those wishing to write or publish information related to WTS may wish to avoid comparing WTS to cigarettes using numerical values as this is a major source of confusion. Future research is needed to address the impact of the media on the attitudes, initiation and cessation rates of waterpipe smokers.

Abstract
BACKGROUND: Mississippi has implemented several programs and policies to reduce youth tobacco. This study examines trends in youth tobacco use and compares current prevalence rates for cigarettes, cigars, smokeless tobacco, and e-cigarettes. DESIGN/METHODS: The Youth Tobacco Survey is a self-administered survey of a multi-stage sample of public high school students. RESULTS: Cigarette and cigar smoking decreased from 1998 to 2014. However, current use of smokeless tobacco did not change and e-cigarette use has increased. Currently, there are no significant differences in the prevalence of cigarette, cigar, smokeless tobacco, or electronic cigarette use. CONCLUSION: The state has successfully decreased cigarette and cigar smoking. However, smokeless tobacco use has not changed and e-cigarettes are becoming increasingly popular. Currently, Mississippi youth are at equal risk for cigarette, cigar, smokeless tobacco, or electronic cigarette use. Tobacco prevention efforts, clinician counseling, and policies should address each of these products rather than focus primarily on cigarettes.

Abstract
BACKGROUND: Smoking is a worldwide problem that kills millions of people. Women smoke much lower than males but the numbers of smoker women are growing up. The objectives of this study were to assess the prevalence of smoking and khat chewing in medical and non-medical female students at University of Science and Technology (UST), Sana'a, Yemen. METHODS: We used self-administrated questionnaire to collect cross-sectional data from a randomly selected sample of medical and non-medical female students of UST in 2012-2013. Overall, 480 students completed and returned the questionnaire, of them medical students represented 50% of them. RESULTS: The prevalence of smoking was significantly low among female medical students (P=0.045), however, not significantly difference was found between medical and non-medical female students in khat chewing habits (P=0.083). Non-smoker medical female students who tried smoking (45.6%) were significantly lower than non-medical students (54.4%), and curiosity was the main reason for trying smoking. Water pipe was the most common type of smoking among smoker students (78.6%). Out of 26 female students who smoke and chew khat, 18 students reported that they smoke more while they chew khat. CONCLUSIONS: Our study highlights the need for increased health education, awareness, and knowledge of the risks of smoking and particularly khat chewing to reduce these habits among female university students especially in non-medical female students.

Abstract
In this study, we examined the effect of theory of planned behavior (TPB) constructs on the intention to quit water pipe smoking by using an observational, survey-based, cross-sectional study design with a convenient sample of Arab American adults in Houston, Texas. Multivariate logistic regression models were used to determine predictors of intention to quit water pipe smoking in the next year. A total of 340 participants completed the survey. Behavioral evaluation, normative beliefs, and motivation to comply were significant predictors of an intention to quit water pipe smoking adjusting for age, gender, income, marital status, and education. Interventions and strategies that include these constructs will assist water pipe smokers in quitting.

Abstract
INTRODUCTION: Studies of social characteristics and substance use patterns among young users of water pipe are rare in Western countries, and no such study has been conducted in Sweden. METHODS: Cross-sectional study based on a national survey conducted in 2011, including 4,710 primary school students (15 years of age) and 3,624 high school students (17 years of age). Prevalence of lifetime and current water pipe use was compared among subgroups defined by other substance use, that is, cigarettes, snus, alcohol, and illicit drugs. Logistic regression was employed to calculate odds ratios (OR) of water pipe use and corresponding 95% confidence intervals (CI), conditionally on sociodemographic characteristics. RESULTS: Use of water pipe was associated with the use of other substances in both age groups. In particular, current use of water pipe at the age of 15 years was strongly associated with current cigarette smoking (OR = 6.46; CI = 5.13-8.14); use of snus (OR = 5.62; CI = 3.94-7.96); binge drinking (OR = 7.39; CI = 5.88-9.31); drunkenness (OR = 7.05; CI = 5.60-8.88); and recent use of illicit drugs (OR = 14.20; CI = 9.18-22.19). Annual alcohol consumption predicted water pipe use in a dose-response fashion. Cigarette smokers willing to quit used water pipe to a lower extent than smokers who did not intend to quit. Being an exclusive smoker of water pipe was associated with substance use when compared with a nonsmoker of tobacco, but not when compared with an exclusive smoker of cigarettes. CONCLUSIONS: Water pipe use among adolescents in Sweden is not a recreational tobacco use alternative to cigarettes and should be regarded as a marker of multiple substance use.

Abstract
OBJECTIVE: To identify determinants of cigarette smoking initiation, by gender, among schoolchildren in Irbid, Jordan. METHODS: Between 2008 and 2011, data were collected annually using self-reported questionnaires over 4-years in a prospective cohort of 1,781 students recruited from all 7th grade classes in 19 secondary schools, selected out of a total 60, using probability-proportionate-to-size method. Independent predictors of smoking initiation were identified among the cigarette naive participants (N = 1,454) with mixed-effect multivariable logistic regression. RESULTS: Participants were 12.6 years of age on average at baseline. 29.8% of the 1,454 students (37.2% of boys and 23.7% of girls) initiated cigarette smoking by 10th grade. Of those who initiated (n = 498), 47.2% of boys and 37.2% of girls initiated smoking in the 8th grade. Determinants of cigarette smoking initiation included ever smoking a waterpipe, low cigarette refusal self-efficacy, intention to start smoking cigarettes, and having friends who smoked. For girls, familial smoking was also predictive of cigarette initiation. CONCLUSION: This study shows that many Jordanian youth have an intention to initiate cigarette smoking and are susceptible to cigarette smoking modeled by peers and that girls are influenced as well by familial cigarette smoking. Prevention efforts should be tailored to address culturally relevant gender norms, help strengthen adolescents' self-efficacy to refuse cigarettes, and foster strong non-smoking social norms.

Abstract
INTRODUCTION: Electronic cigarette (e-cigarette) use is increasing rapidly, and the impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among US youth who had never smoked conventional cigarettes. METHODS: We analyzed data from the nationally representative 2011, 2012, and 2013 National Youth Tobacco Surveys of students in grades 6-12. Youth reporting they would definitely not smoke in the next year or if offered a cigarette by a friend were defined as not having an intention to smoke; all others were classified as having positive intention to smoke conventional cigarettes. Demographics, pro-tobacco advertisement exposure, ever use of e-cigarettes, and ever use of other combustibles (cigars, hookah, bidis, kreteks, and pipes) and noncombustibles (chewing tobacco, snuff, dip, snus, and dissolvables) were included in multivariate analyses that assessed associations with smoking intentions among never-cigarette-smoking youth. RESULTS: Between 2011 and 2013, the number of never-smoking youth who used e-cigarettes increased 3-fold, from 79,000 to more than 263,000. Intention to smoke conventional cigarettes was 43.9% among ever e-cigarette users and 21.5% among never users. Ever e-cigarette users had higher adjusted odds for having smoking intentions than never users (adjusted odds ratio = 1.70, 95% confidence interval = 1.24-2.32). Those who ever used other combustibles, ever used noncombustibles, or reported pro-tobacco advertisement exposure also had increased odds for smoking intentions. CONCLUSION: In 2013, more than a quarter million never-smoking youth used e-cigarettes. E-cigarette use is associated with increased intentions to smoke cigarettes, and enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes.
