METHODS: Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette smokers [mean age = 23.5 (SD = 5.5); 65% female]. RESULTS: Higher receptivity to e-cigarette marketing was associated with perceptions that e-cigarettes are less harmful than cigarettes, which in turn, were associated with higher recent e-cigarette use. CONCLUSIONS: The findings provide preliminary support to the proposition that marketing of e-cigarettes as safer alternatives to cigarettes or cessation aids is associated with increased e-cigarette use among young adults. The findings have implications for development of e-cigarette regulations. Descriptors Links Book Title Database Publisher Data Source Authors Pokhrel,P., Fagan,P., Kehl,L., Herzog,T.A.

MATERIALS AND METHODS: This study employed a cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul. The questionnaire featured a section about use of substances, including tobacco, alcohol, and drugs. The depression, anxiety, anger, assertiveness, sensation seeking and impulsiveness subscales of the Psychological Screening Test for Adolescents (PSTA) were used. The analyses were conducted based on 4957 subjects. RESULTS: Logistic regression analyses were conducted with each school with the related and behavioral variables as the dependent variables. Gender, tobacco, alcohol, and drug use being the independent variables. All four independent variables predicted the dependent variables. Lifetime tobacco and drug use had significant effects on all the subscale score, whereas lifetime alcohol use had significant effects on all the subscale scores other than lack of assertiveness, and male gender was a significant covariant for all the subscale scores. Drug use showed the highest effect on dependent variables. Interaction was found between effects of tobacco and alcohol on anxiety, whereas interactions were found between effects of tobacco and drugs on lack of assertiveness and impulsiveness. CONCLUSION: The findings suggested that male students with lifetime tobacco, alcohol or drug use have particularly high risk of psychological and behavioral problems. The unique effects of substance clusters on these problems may be useful in developing secondary preventive practices for substance use and abuse problems in Istanbul.

Simultaneous separation and determination of nine hydroxylated polycyclic aromatic hydrocarbons and two hydroxy biphenyls could be performed in negative mode with a run time of 12 min, including equilibration in 5 min. The calibration curves were in two concentration ranges; 1-50 ng/mL and 0.01-50 mug/mL, with coefficients of correlation R (2) > 0.997. The limits of detection and method quantification limits were in the range of 9-56 pg and 5-38 ng/g, respectively. A two-level full factorial experimental design was used for screening of conditions with the highest impact on the extraction. The extraction procedure was automated and suitable for a large number of samples. The extraction recoveries ranged from 70 to 102 % and the matrix effects were between 92 and 104 %. The overall method was demonstrated on wood smoke particles and soil samples with good analytical performance, and five OH-PAHs were determined in the concentration range of 0.19-210 mug/g. As far as we know, hydroxylated polycyclic aromatic hydrocarbons were determined in wood smoke and soil samples using photoionization mass spectrometry for the first time in this present study. Accordingly, this study shows that high performance liquid chromatography photoionization tandem mass spectrometry can be a good option for the determination of hydroxylated polycyclic aromatic hydrocarbons in complex environmental samples. Graphical Abstract The method developed in this study was used to determine hydroxylated polycyclic aromatic hydrocarbons in wood smoke and soil.

We examined the correlates associated with e-cigarette awareness, use and perceived effectiveness in smoking cessation among Chinese daily smokers in Hong Kong. METHODS: Daily smokers (N = 1,307) were recruited to a community-based randomised controlled trial ('Quit to Win') in 2014. Socio-demographic characteristics, conventional cigarette smoking status, nicotine addiction level, quit attempts, quit intention, e-cigarette awareness, use and perceived effectiveness on quitting were reported at baseline and 1-week follow-up. Multivariate logistic regression was used to identify factors associated with e-cigarette awareness, use and perceived effectiveness in quitting. RESULTS: Most smokers (82.6%, 95% CI 80.2%-84.9%) had heard about e-cigarettes, and 13.3% (11.3%-15.5%) ever used e-cigarettes. Most users (74.1%) and non-users (91.2%) did not perceive e-cigarettes as effective in quitting. Being younger and having a larger family income were associated with e-cigarette awareness. Being younger, a tertiary education and a stronger addiction to nicotine were associated with e-cigarette use, which was itself associated with lower levels of intention to quit and had no association with attempts to quit (P for trend 0.45). E-cigarette use, the last quit attempt being a month earlier, having made a quit attempt lasting 24 hours or longer and perceiving quitting as important were all associated with the perceived effectiveness of e-cigarettes in quitting (all P Descriptors Links Book Title Database Publisher Data Source Authors Wang,M.P., Li,W.H., Jiang,N., Chu,L.Y., Kwong,A., Lai,V., Lam,T.H.

For two 3-week periods occurring 6 months before and after the election, a 1% random sample was obtained of all tweets matching a set of marijuana-related queries. Original content was separated from reposted content (retweets), and foreign language tweets and those not related to marijuana were excluded. Using a structured codebook, tweet content was categorized (e.g., mention of personal marijuana use, parents' views, perceived effects.) Self-reported age was extracted from tweet metadata when available. Chi-square tests were used to assess differences in content by whether the user self-identified as an adolescent and to compare content pre- versus post-election. The full sample consisted of 71,901 tweets. After excluding nonrelevant tweets and separating original tweets from retweets, the analytic sample included 36,969 original tweets. A majority (65.6%) of original tweets by adolescents (n=1,928) reflected a positive attitude toward marijuana, and 42.9% indicated personal use. Of adolescents' tweets that mentioned parents, 36.0% of tweets indicated parental support for the adolescent's marijuana use. Tweets about personal marijuana use increased from 2012 to 2013, as did positive perceptions about the drug. Adolescents and others on Twitter are exposed to positive discussion normalizing use. Over the study period, Twitter was increasingly used to disclose marijuana use. Descriptors Links Book Title Database Publisher Data Source Authors Thompson,L., Rivara,F.P., Whitehill,J.M.

It is important to understand their existing level of awareness and support for national anti-tobacco policies. We thus aim to explore Pakistani HP students' existing attitudes towards national anti-tobacco policy and examine factors associated with lack of awareness, and support amongst them. METHODS: Secondary data analysis of the Global Health Professional Students Survey, Pakistan, 2011 was performed. Study population included 4,235 health professional students enrolled in third year of graduate level HP programs. The policy support metrics were developed using six questions from the survey. Univariate and multivariate analyses were conducted to analyze association between HP students' awareness, and support for anti-tobacco policy (outcome variables), and various socio-demographic, attitudinal, and knowledge related factors. Descriptive statistics are reported as proportions, and results of logistic regression analysis were reported as odds ratios with 95% confidence interval. RESULTS: Overall, among HP students, 10.8% (n=391) were current smokers, and 26.7% (n=965) of them were cigarette experimenters. Almost half, (46.1%, n=1666) of the HP students did not have an awareness of the official policy banning tobacco use in their school buildings and clinics; and only one in ten (9.4%, n=338) of them did not support anti-tobacco policies. Students were less likely to be aware if they had second hand exposure at home/work (OR=0.73, 95% CI (0.57-0.92), p-value Descriptors Links Book Title Database Publisher Data Source Authors Aslam,S.K., Mehboob,B., Zaheer,S., Shafique,K.

For this, whole chromosome sequences of Leuconostoc mesenteroides, Lactobacillus plantarum, and Lb. brevis were compared and species-specific PCR primers targeting dextransucrase, 16S rRNA, and surface layer protein D (SlpD) genes, respectively, were constructed. The tested strains were quantified both in medium and kimchi by CQ-PCR and the results were compared with the data obtained using a conventional plate-counting method. As a result, the three species were successfully detected and quantified by the indicated primer sets. Our results show that the CQ-PCR method targeting species-specific genes is suitable for rapid estimation of LAB population to be used in the food fermentation industry.

The objective of this study was to investigate the effect of short-term switching between smoker's own brand and test cigarettes with different smoke yields on puffing topography, respiratory parameters and biomarkers of exposure. Participants were randomly assigned to smoke either a Test Cigarette-High Tar (TCH), for two days, and then switched to a Test Cigarette-Low Tar (TCL), for two days or the reverse order (n = 10 each sequence). Puffing topography (CReSS microdevice), respiratory parameters (inductive plethysmography) and biomarkers of exposure (BOE, urinary nicotine equivalents - NE and blood carboxyhemoglobin - COHb) were measured at baseline and on days 2 and 4. The average puffs per cigarette, puff volume and puff durations were statistically significantly lower, and inter-puff interval was significantly longer for the TCH compared to the TCL groups. Respiratory parameters were not statistically significantly different between the TCH and TCL groups. Post-baseline NE and COHb were statistically significantly lower in the TCL compared to the TCH groups. Under the conditions of this study, we found no indication of changes in respiratory parameters, particularly inhalation time and volume, between study participants smoking lower versus higher yield cigarettes. Likewise, the BOE provides no indication of deeper inhalation when smoking low- versus high-yield cigarettes. These findings are consistent with the published literature indicating smoking low-yield cigarettes does not increase the depth of inhalation.

Proper application of e-cigarettes to smoking cessation or tobacco harm reduction would require an understanding of when and why dual users use cigarettes versus e-cigarettes. This study sought to elucidate the contexts of cigarette versus e-cigarette use among dual users. METHODS: Twelve focus group discussions were conducted with 62 young adult current daily e-cigarette users [63% men; mean age = 25.1 (Standard Deviation = 5.5)]. Almost all participants either concurrently smoked cigarettes or had been recent dual users. Data were analyzed following principles of inductive deduction. RESULTS: Results indicated that dual users' use of cigarettes is influenced by particular activities (e.g., before/after eating), strong craving or need for stimulation (e.g., in response to stress), places/situations (e.g., when cigarette smokers are nearby; outdoors), use of other substances (alcohol, coffee), and unavailability of an e-cigarette when needed. In addition to particular activities and places/situations that are conducive to e-cigarette use, use of e-cigarette when cigarette is not available or where cigarette smoking is not permitted emerged as contexts specific to e-cigarette use. CONCLUSIONS: For habitual cigarette smokers wanting to quit tobacco smoking, switching over completely to e-cigarettes may require skills of cognitive-behavioral management. Future research needs to ascertain the characteristics of dual users who use e-cigarettes as cessation aids versus as cigarette alternative when cigarette is unavailable or smoking is not permitted.
