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] 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.

[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.

This study provides an overview of five e-cigarette case samples seized from Scottish prisons between May 2022 and July 2023 where the anabolic-androgenic steroids (AASs) mestanolone and oxandrolone were identified following gas chromatography-mass spectrometry (GC-MS) analyses. These e-cigarette samples
represented 2.9% of all samples containing e-cigarette cartridges (n = 170) and 9.4% of all samples found to contain AASs (n = 53) seized during the same time period. The AASs were detected in combination with other drugs, including cocaine, Δ9-tetrahydrocannabinol (Δ9-THC), SCRAs and nicotine. This represents a new and novel route of administration for AASs.

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.

E-cigarettes, also referred to as electronic cigarettes, are gaining popularity as an alternative to tobacco use. Although their use has significantly increased recently, there is still much debate over their effectiveness and safety as smoking cessation aids.
Objective:
This review paper’s objective is to offer an inclusive evaluation of the body of research about the impact of ecigarettes on the oral microbiome and oral health.
Methodology: Data was extracted from PubMed, Google Scholar, and Scopus to compile scientific evidence for a narrative review article on the effects of e-cigarettes on the oral microbiome. The investigation was restricted to published research articles from 2001 to 2022, using pre-defined search phrases for e-cigarettes, vaping, quitting smoking, oral microbiota, and oral health.
Results:
The chemicals in e-cigarettes, including nicotine, propylene glycol, vegetable glycerin, flavorings, and chemical additives, cause a dysbiosis that can lead to a variety of conditions, including dental caries, periodontal diseases, and a variety of mental health issues, such as bone loss, gingival tissue inflammation, and increased plaque accumulation. The chemical toxicity of e-cigarettes, including nicotine and other components present in e-cigarette aerosols, has been implicated in various oral health problems that lead to systemic complications.
Conclusion:
A wide range of oral health sequelae may be associated with e-cigarette use. Future investigation should focus on elucidating the long-term effects of e-cigarette use onPermalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10196 Aucun avis, veuillez vous identifier pour ajouter le vôtre !
Titre : Electronic cigarette (e-cig) use in the chronic pain population Type de document : document électronique Auteurs : John Maclean, Auteur ; Skylar Remick, Auteur ; Woo Jun Shim, Auteur ; Anil Chakravorty, Auteur ; Chong Kim, Auteur Editeur : Paducah [Etats-Unis] : American Society of interventional pain physicians Année de publication : 2024 Collection : Pain physician journal Importance : p. 263-367 Présentation : tab.

[TABAC] tabagisme:tabagisme actifMots-clés : douleur chronique Index. décimale : TA 2.2 Pays industrialisés Résumé : Background:
Since electronic cigarettes (E-Cigs) were introduced to the United States (US) in 2007 its use has increased. Like other tobacco products, E-Cigs too pose health risks. Studies
have shown a correlation between pain and tobacco use, with the association being bidirectional. However, there is limited data on the effect of E-Cig use on chronic pain, as well as its association with opioid use.
Objectives:
To evaluate the use of tobacco products, including E-Cigs in a chronic pain population. Study Design: This study was designed as a cross sectional survey.
Setting:
This study was set in an urban academic teaching center.
Methods:
After IRB approval, surveys of established chronic pain patients were conducted over 4 months. The survey and results were anonymous, without the collection of any identifiable
information. The adult patients who had been treated in the pain practice for over 3 months were included in this study. The survey collected the patients’ age, gender, history of tobacco usage, cigarette smoking, E-Cig and opioid use.
Results:
A total of 312 patients were surveyed. 198 women (63.5%) and 114 men (36.5%). The average age was 58.2; ~59 years for men and ~58 years for women. Eighty-four patients (26.9%)
were managing pain using chronic opioids; 46 women and 38 men. Nine women (4.5%) had tried E-Cigs in the past, but none (0%) were active users. Eighteen men (15.8%) had tried E-Cigs in the past with 9 (7.8%) being active users. Among the opioid managed patients, 6 (9.1%) had and were active users of E-Cigs and all 6 were men (20%).
Limitations:
The anonymous results collected through the survey may not be accurate as they cannot be validated. In addition to the small sample size, the entire study population is from an
urban academic center which may not be generalizable to all chronic pain patients. Finally, the study does not evaluate the impact of tobacco or E-Cig use on pain level or functional status.
Conclusion:
In this study of chronic pain patients, cigarette smoking and E-Cig use was similar to the reported use in the general adult population in the US. The study showed a strong correlation
between tobacco use, especially cigarettes and E-Cigs, and opioid use. As the use of E-Cigs becomes more mainstream, the association between E-Cig use, chronic pain, and opioid use
should be monitored.

Index. décimale : TA 3.2.2.5 Pathologies cardiovasculaires Résumé : Electronic cigarettes (e-cigarettes), as alternative nicotine delivery methods, has rapidly increased among youth and adults in recent years. However, cardiovascular safety is an important consideration regarding e-cigarettes usage. e-cigarette emissions,including nicotine, propylene glycol, flavorings, nitrosamine, and metals, might have adverse effects on cardiovascular health. A large body of epidemiological evidence has indicated that e-cigarettes are considered an independent risk factor for increased rates of cardiovascular disease occurrence and death. The incidence and mortality of various types of cardiovascular disease, such as cardiac arrhythmia, hypertension, acute coronary syndromes, and heart failure, have a modest growth in vapers (users of e-cigarettes). Although the underlying biological mechanisms have not been fully understood, studies have validated that oxidative stress, inflammation, endothelial dysfunction, atherosclerosis, hemodynamic effects, and platelet function play important roles in which e-cigarettes work in the human body.

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 !

[TABAC] tabagisme:pathologie:pathologie respiratoireIndex. décimale : TA 3.2.2.1 Expérimentation Résumé : E-cigarettes are devices used to deliver vaporized liquids often containing nicotine and other chemicals. 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.

Study one employs the McGuire’s Communication/Persuasion model to identify research gaps in the literature on health messages targeting youth e-cigarette use. The systematic review reveals a lack of research specifically targeting vaping cessation among youth who currently use e-cigarettes. As a result, the
subsequent studies in this dissertation focus on youth vaping cessation to address this research gap. Study two presents a content analysis of existing vaping-cessation related TikTok videos. The findings of study 2 suggest that themes pertaining to physical health outcomes, nicotine addiction, harmful chemicals, and relatable message sources were associated with higher engagement, underscoring the importance of tailored messaging content and relatable sources to engage the young audience on TikTok. Study 3 consists of an experimental study that specifically examines the effects of message frames (gain vs. loss) and two types of expert message sources (formal vs. informal expert sources) on youth intention to quit vaping. The study found that TikTok videos employing gainviii framed messages hold promise in promoting positive emotional responses and, consequently, intention to quit vaping among youth. Lastly, chapter 5 provides a summary of the findings within this dissertation, offering insights into future research directions and proposing practical implications derived from the three studies.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10209 Aucun avis, veuillez vous identifier pour ajouter le vôtre !
