Here, we describe a multiple test matrix and
in vitro approach to assess the biological impact of differing e-cigarette activation mechanism (button vs puff-activated) and heating technology (cotton vs ceramic wick). The e-liquids selected for each device contained the same nicotine concentration and flavourings. We tested both e-liquid and aqueous extract of e-liquid aerosol using a high throughput
cytotoxicity and genotoxicity screen. We also conducted whole aerosol assessment both in a reconstituted human airway lung tissue (MucilAir) with associated endpoint assessment
(cytotoxicity, TEER, cilia beat frequency and active area) and an Ames whole aerosol assay with up to 900 consecutive undiluted puffs. Following this testing it is shown that the
biological impact of these devices is similar, taking into consideration the limitations and capturing efficiencies of the different testing matrices. We have contextualised these
responses against previous published reference cigarette data to establish the comparative reduction in response consistent with reduced risk potential of the e-cigarette products
tested in this study as compared to conventional cigarettes.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10187 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] tabagisme:risque:facteur associé:drogue:cannabisIndex. décimale : TA 1.1.5 Cannabis Résumé : Purpose:
Co-use of tobacco and cannabis is a common and complex behavior. The lack of harmonized measures of co-use yields confusion and inconsistencies in synthesizing evidence about the health effects of co-use. We aimed to classify co-use patterns based on temporal proximity and describe preferred products and motives for each
pattern in order to improve co-use surveillance.
Methods: We conducted semi-structured interviews in a sample of 34 young adults (Mage = 22.8 years, 32.4 % female) during 2017–2019 in California, USA. We employed a qualitative thematic analysis to identify timing, reasons, and contexts for tobacco and cannabis co-use and classify co-use patterns.
Results:
Four emergent patterns of co-use with increasing temporal proximity between tobacco use and cannabis use were: Same-month different-day co-use (Pattern 1); Same-day different-occasion co-use (Pattern 2); Same-occasion sequential co-use (Pattern 3); and Same-occasion simultaneous co-use (Pattern 4). Participants used various product combinations within each pattern. Similar motives for all patterns were socialization, product availability, and coping with stress/anxiety. Unique motive for temporally distant patterns (Patterns 1 and 2) was seeking substancespecific effects (e.g., stimulant effect from nicotine, relaxation effects from cannabis), while unique motives for temporally close patterns (Patterns 3 and 4) were seeking combined effects from both substances (e.g., more intense psychoactive effects, mitigating cannabis adverse effects) and behavioral trigger (e.g., cannabis use triggers tobacco use).
Conclusions:
Our classification of co-use patterns can facilitate consistency for measuring co-use and assessing its health impacts. Future research should also measure product types and motives for different patterns to inform intervention efforts.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10207 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] prévention:campagne:campagne médiatique:internetIndex. décimale : TA 9.1.2 Publicité Résumé : Background: The WHO Framework Convention on Tobacco Control (WHO FCTC) Article 13 requires countries to ban tobacco advertising, promotion and sponsorship (TAPS), and bans are recommended to cover electronic cigarettes (e-cigarettes). We examined youth e-cigarette prevalence by TAPS regulations in countries with different income levels.
Methods: We analysed data on 165 299 respondents from 48 countries with 2016/2018 WHO FCTC implementation reports and 2016-2019 Global Youth Tobacco Survey. We used multilevel logistic regressions to examine associations between TAPS regulations and current e-cigarette use, stratified by country income.
Results: About 1 in 10 respondents was currently using e-cigarettes. Respondents in countries with TAPS bans on the internet were less likely to use e-cigarettes (adjOR=0.58; 95% CI 0.39 to 0.86) than youth in countries without such bans. In lower middle-income and low-income countries, bans on displaying tobacco products at the point of sale (adjOR=0.55; 95% CI 0.34 to 0.90), bans on product placement (adjOR=0.44; 95% CI 0.28 to 0.69) and strength of additional TAPS measures were associated with lower prevalence of e-cigarette use among students. Being taught about the dangers of the use of tobacco in school was associated with lower odds of e-cigarette use. No differences in the use of e-cigarettes were observed by types of TAPS among respondents in high-income countries.
Conclusions: Strengthening implementation of TAPS policies and assuring they cover new and emerging products, online channels and points of sales are essential, especially in lower income countries. Maintaining tobacco health education is also important to protect youth from e-cigarette use.

Methods: A total of 160 participants were divided into four groups according to the type of product used, including non-smokers, users of conventional combustible tobacco (cigarettes), heated tobacco, and electronic, tobacco-free vapor products (e-cigarettes). Buccal mucosa samples were analyzed using the micronucleus cytome assay
to assess cytotoxic and genotoxic damage.
Results: E-cigarette users showed significantly higher values for all tested parameters in the micronucleus test compared to non-smokers (p < 0.05). Similarly, users of tobacco heating products showed an increase in all parameters (p < 0.05), with the exception of the number of cells with micronuclei. Conventional cigarette smokers showed a notable increase in the number of binucleated cells and cells with karyorrhexis and karyolysis (p ≤ 0.05). When assessing the differences between users of traditional combustible tobacco products and non-combustible alternatives, these did not appear to be significant, except for e-cigarette users, who had significantly more cells with condensed chromatin (p ≤ 0.001), while users of tobacco heating products had more pyknotic cells (p ≤ 0.001).
Conclusion: The results of this study underscore the heightened occurrence of cytotoxic and genotoxic damage in users of both conventional combustible tobacco products and non-combustible alternatives compared to non-smokers, emphasizing the detrimental impact of these products on the oral mucosa.

[TABAC] étudeIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : Introduction: Heated tobacco products (HTPs) are novel tobacco products that may appeal to youth. This study explored whether HTP retailer proximity and density to secondary schools were associated with youth use of HTPs in four Canadian provinces.
Methods: An online search between November 2020 and March 2021 identified retailers selling IQOS devices and HEETS (tobacco sticks used in IQOS) within 500 m, 1000 m and 1500 m radius circular buffer zones around high schools (N = 120) participating in the COMPASS study in 2020–2021. Retailer proximity/density data were linked to crosssectional student-level data (N = 40 636 students), and multilevel regression models examined the association between HTP retailer proximity and density and current HTP use, controlling for relevant covariates.
Results: While only 10.0% of schools had at least one retailer selling IQOS devices within 1000 m of the school, 65.0% of schools had at least one retailer selling HEETS. The school a student attended accounted for 23.7% of the variability in the likelihood of currently using an HTP. However, HTP retailer proximity to and density around schools were not significantly associated with the likelihood of students currently using HTPs.
Conclusion: While the school a student attended accounted for a significant amount of variability in HTP use, these findings suggest that students may be obtaining HTPs through other, non-retail sources. Continued monitoring is warranted as HTP use among youth may change.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10181 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

The study aimed to investigate the utility of telemedicine conducted via video counseling in comparison to the previous structured approach and to compare prepandemic smoking cessation success rates with traditional counseling.
MATERIAL AND METHODS:
The applicants of the outpatient clinic for smoking cessation support pre- and post-pandemic periods were included in the study. The time intervals were retrospectively between 1 March and 30 August 2021 and the last 3 months of the year 2019. The data were revealed retrospectively. Age, sex, occupation, smoking history as package year, and the score of the Fagerström test for nicotine dependence, accompanying chronic diseases, treatment method, and quitting status between 6 and 9 months of follow-up.
RESULTS:
The number of applicants was 200 (87% male) and 89 (95% male) in groups 1 and 2, respectively. The age difference was not significant. The difference was statistically significant according to having at least 1 accompanying chronic disease, specifically a lung disease. None of the parameters have affected the success of quitting smoking. The smoking cessation rate was 3.9 fold higher in the telemedicine group than in the traditional group.
CONCLUSION:
The main principle appears to be allocating enough time, as required on an individual basis, to clearly assess the situation, including identifying barriers and options. Since immediate systematic physical examination and laboratory testing may not be mandatory for individuals seeking smoking cessation support, telemedicine emerges as a reasonable option and a promising field for comprehensive video counseling.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10219 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] prévention:campagne:campagne médiatique:internetMots-clés : Pouche Index. décimale : TA 8.8 Publicité Résumé : Oral nicotine pouches, which contain fewer harmful constituents than traditional tobacco products, are being increasingly marketed and sold. In this paper, we use images we collected in Great Britain between 2021 and 2023, along with a social media scan of Instagram and TikTok in 2023 to analyse the marketing strategies of these pouches on three key marketing channels — online media, sports sponsorships, and out-of-home advertising. Findings reveal the extensive use of visually appealing content, influencer partnerships, and event sponsorships that are potentially targeting young and naive audiences. Despite this, survey data indicates that nicotine pouch use in Great Britain remains minimal. However, a notable shift in public health impact could arise if these marketing efforts start to bear more fruit. The study underscores the need for balanced policy measures that increase access to reduced harm alternatives for existing tobacco and nicotine users while minimising exposure to youth and non-users. Continuous monitoring and regulatory adjustments are essential to address the evolving landscape of nicotine pouch marketing Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10174 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

revue de la littératureIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : There is ongoing scientific and policy debate about the role e-cigarettes play in tobacco control, with concerns centring around unknown long-term effects, and the potential industry cooption
of harm reduction efforts, including marketing to youths. There is substantial evidence of the influence of conventional cigarette promotion on smoking behaviours in Anglophone countries, and the popularity of social networking sites, as well as the lack of marketing regulations on the commercial promotion of electronic cigarettes online, suggest an urgent need to explore this topic further. This scoping review aims to map the existing evidence related to the influence of e-cigarette commercial promotion on social media on positive perceptions of vaping and vaping behaviours in core Anglophone countries. Searches were conducted in CENTRAL, Cochrane Database of Systematic Reviews (CDSR), Embase, Epistemonikos, MEDLINE, PsycINFO and Science Citation Index, on the 21st of July 2022. From 1,385 studies, 11 articles were included in the final review, using diverse study designs, including focus groups, content analysis, cross-sectional studies, and experiments.
The studies were primarily based in the U.S. and evidenced the association between the commercial promotion of e-cigarettes on social media with positive perceptions of vaping and vaping behaviours, particularly among young people, addressing diverse themes including celebrities’ sponsorship, e-liquid appeal (including flavours and nicotine levels), users’ engagement with ads, and other marketing strategies. Further, social networking sites commercially promoting e-cigarettes might increase positive attitudes towards vaping and vaping behaviours, particularly among youths. Future research should be conducted in broader settings, incorporate larger and diverse sample sizes, ensure research transparency, cover multiple social networking sites, emphasize ecological validity, and foment longitudinal studies.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10180 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

The aim of the study is to determine the tobacco use status of first and fifth grade students studying at Dokuz Eylül University Faculty of Medicine in the 2022-2023 academic year and to evaluate the factors affecting tobacco use.
MATERIAL AND METHODS:
The data of the cross-sectional study were obtained by sending a form prepared in electronic environment to the students after a brief information was given in the unit/classroom where they did their internship, and the students responded on their mobile phones. In research, 539 of 790 students answered the form.
RESULTS: The prevalance of tobacco use was 34.1% (first: 29.8%, fifth: 40.8%) (female: 26.7%, male: 40.4%). According to multivariate analysis, tobacco use in first grades increases 1.8 times (95% CI: 1.1-3.3) if the general health perception is moderate/poor, 2.9 times (95% CI: 1.2-6.8) to be exposed to insistence of friends for tobacco use, 2.4 times (95% CI: 1.3-4.3) for at least one of the family members to use tobacco, 29.7 times (95% CI: 3.9-224.1) for at least one of the close friends to use tobacco, and 3.9 times (95% CI: 2.2-7.1) not to think that physicians should set an example for the society by not using tobacco; in fifth grade, tobacco use by at least one of the close friends increases 9.6 times (95% CI: 2.1-43.6), and not thinking that physicians should set an example for the society by not using tobacco increases 4.9 times (95% CI: 2.7-9.2).
CONCLUSION: In research, it is seen that tobacco use is common among medical faculty students, and the prevalance of use increases

[TABAC] étudeMots-clés : Pharmacocinétique - e-liquide Index. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : The addition of protonating acids to e-cigarette liquid formulations (e-liquids) enhances nicotine bioavailability in e-cigarette use. However, little is known about the impact of different combinations of protonating acid on nicotine pharmacokinetics. The objectives of this study were to compare pharmacokinetics of nicotine absorption following use of a closed-system e-cigarette, containing e-liquids with two different nicotine levels and with different ratios of three common protonating acids—lactic, benzoic and levulinic. In a randomised, controlled, crossover study, nicotine pharmacokinetics and product liking were assessed for prototype e-liquids used in a Vuse e-cigarette containing either 3.5% or 5% nicotine and varying ratios of lactic, benzoic and/or levulinic acid. During an 8-day confinement period, 32 healthy adult current cigarette smokers/e-cigarette dual users used a single study e-liquid each day during 10-min fixed and ad libitum use periods after overnight nicotine abstinence. For most comparisons, Cmax and AUC 0–60 following both fixed and ad libitum puffing were significantly higher for e-liquids containing 5% nicotine compared with 3.5% nicotine. However, Cmax and AUC 0–60 were not statistically different for 5% nicotine e-liquids containing varying ratios of lactic, levulinic and benzoic acid when compared to an e-liquid containing lactic acid only. Mean scores for product liking were similar for all e-liquid formulations assessed, regardless of nicotine concentration, acid content, and whether the product was used in a fixed or ad libitum puffing regimen. While e-liquid nicotine concentration significantly affected users’ nicotine uptake, the different combinations of benzoic, levulinic and lactic acid in the e-liquids assessed had limited impact on nicotine pharmacokinetics and product liking scores.

Grade 12 students (N = 855) of 2020 from nine Australian schools completed a cross-sectional self-report survey. Correlates examined included age, gender, Aboriginal or Torres Strait Islander, parental and family characteristics, truancy, mental health (depression and anxiety), alcohol use and cigarette smoking. Overall, 74% reported that they had never used an e-cigarette or vaped, 12.5% had for flavour-only, and 13.5% had for nicotine vapes. Multinomial adjusted logistic regressions showed that males and teens reporting frequent alcohol or cigarette use had higher odds of vaping. In adolescents who had used an e-cigarette, half had used a nicotine vape. Those who engaged in risky drinking and smoked cigarettes were most likely to also use e-cigarettes, implying that this may be a high-risk group.

The purpose of this study was to investigate the effects of 14 days of e-cigarette vapor exposure in adolescent rats on lung function and inflammatory cytokine expression. Seventeen male Long-Evans rats were assigned to vape or air groups. The animals were exposed to either air or 5% nicotine vapor using a whole-body exposure chamber, once a day for ten minutes for fourteen consecutive days. Ventilation recordings were completed on day 0 (before exposure) and day 15 (after exposure) using unrestrained whole-body plethysmography. Both lung tissue and blood was collected for mo-lecular assays. Baseline and post-exposure ventilation data were compared between air and vape groups across three different parameters: frequency, tidal volume, and minute ventilation. These parameters were compared resulting in three distinct 2x2 (time x treatment) Mixed Model ANOVAs. Between baseline and post-treatment measurements there was a significant decrease in values in minute ventilation (p=0.0312) and tidal volume (p=0.0031). Between treatment groups there was a significant difference in minute ventilation (p=0.0128) and frequency (p=0042). There were also significant alterations to the presence of IL-1β in the serum (p=0.0003), but not lung tissue (p=0.6525). In conclusion, following two weeks of e-cigarette vapor exposure, ventilation patterns were altered in the vapor exposed animals which decreased in tidal volume and minute ventilation suggesting possible impairment of lung function and e-cigarette exposure modified the expression of pro-inflammatory cytokine, IL-1ꞵ.

Although the relationship between tax and price and youth cigarette use is well established, little is known about these associations and youth e-cigarette use. This research examines U.S. youth sensitivity to changes in e-cigarette prices and tax using standardized measures of e-cigarette taxes and prices.
Methods:
This analysis uses national data on past 30-day use and the number of days using e-cigarettes (i.e., the intensity of use) from the repeat cross-sectional 2015−2019 Youth Risk Behavior Survey, in combination with inflation-adjusted standardized e-cigarette price and tax data to understand whether changes in e-cigarette price and tax were associated with changes in e-cigarette use. Two-part demand regression models controlling for demographics and e-cigarette restriction policies
were conducted to calculate price and tax elasticities of demand, in addition to $0.50 and $1.00 price and tax increase simulations.
Results: Increased e-cigarette prices and taxes were associated with significant reductions in past 30-day use. Prices were also significantly associated with decreases in the intensity of use. A $0.50 and $1.00 tax increase leads to a 6.3% and 12.2% decrease in past 30-day use and a 4.7% and 9.3% decrease in intensity, respectively. A $0.50 and $1.00 price increase leads to a 4.1% and 8.2% decrease in past 30-day use and a 4.2% and 8.3% decrease in intensity, respectively.
Conclusions: Higher prices and taxes reduce youth current e-cigarette use and days using e-cigarettes. Policies increasing e-cigarette prices, such as excise taxes, can reduce youth current e-cigarette use and days using e-cigarettesPermalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9801 Aucun avis, veuillez vous identifier pour ajouter le vôtre !
