[TABAC] étudeIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : Introduction:
Many carbonyls are produced from the combustion of tobacco products and many of these carbonyls are harmful or potentially harmful constituents of mainstream cigarette smoke.
One carbonyl of particular interest is acrolein, which is formed from the incomplete combustion of organic matter and the most significant contributor to non-cancer respiratory effects from cigarette smoke. Sheet-wrapped cigars, also known as “little cigars,” are a type of tobacco products that have not been extensively investigated in literature.
Methods:
This study uses standard cigarette testing protocols to determine the acrolein yields from sheet-wrapped cigars. Sheet-wrapped cigar and cigarette products were tested by derivatizing the mainstream smoke with 2,4-dinitrophenylhydrazine (DNPH) solution and then quantifying the derivatives using conventional analytical systems.
Results:
The results demonstrate that sheet-wrapped cigars can be tested for acrolein yields in mainstream smoke using the same methods used for the evaluation of cigarettes. The variability in the sheet-wrapped cigars and cigarettes under the International Organization for Standardization smoking regimen is statistically similar at the 95% confidence interval; however, increased variability is observed for sheet-wrapped cigar products under the Health Canada Intense (CI) smoking regimen.
Conclusion: The amount of acrolein released by smoking sheet-wrapped cigars can be measured using standard smoking regimen currently used for cigarettes. The sheet-wrapped cigars were determined to yield similar quantity of acrolein from commercial cigarette products using two standard smoking regimens.
Implications:
This article reports on the measured quantity of acrolein from 15 commercial sheetwrapped cigars using a validated standard smoking test method that derivatizes acrolein in the
mainstream smoke with DNPH solution, and uses Liquid Chromatography/Ultra-Violet Detection (LC/UV) for separation and detection. These acrolein yields were similar to the levels found in the smoke from 35 commercial cigarette products measured in the same manner. Although sheetwrapped cigar data were slightly more variable than those found for the cigarette data, this article reports that the production of acrolein is similar to cigarettes. The results demonstrate that sheet-wrapped cigars can be tested for acrolein yields in mainstream smoke using the same methods used for the evaluation of cigarettes.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9705 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] tabagisme:tabagisme actifMots-clés : vapotage Index. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : In 2019, a respiratory infection outbreak in individuals with a history of vaping was discovered, this condition was eventually termed e-cigarette or vaping product use–associated lung injury (EVALI) after it was linked to lung damage during imaging and histopathologic examination. The exact mechanism behind the lung injury seen in EVALI is unknown. Several studies show that EVALI has been associated with the incidence of acute respiratory distress syndrome. Nowadays, many people use Vapes/e-cigarettes, it is critical for clinicians to understand the hazards of using e-cigarettes, which can induce EVALI to ARDS. We used a number of research resources, including ScienceDirect, Google Scholar, PubMed, and Wiley, to search, select, and choose papers about the use of electronic cigarettes or vaping devices associated to lung injury trigger Acute Respiratory Distress syndrome. The literature search yielded 330 articles, of which 21 met the selection criteria based on the title and abstract. EVALI is still a clinical diagnosis that should be considered as an exclusion because the symptoms, physical examination, serologic, radiologic, and bronchoscopy results are not specific to the illness alone. ARDS and its sequelae may be more likely to occur in patients with EVALI who also have several chronic illnesses. For individuals who use excessively and consistently over weeks or months, there is strong correlative evidence suggesting a higher risk of VAPI and potential consequences from ARDS in the absence of prompt and aggressive therapy.

E-cigarettes are the most commonly used tobacco product among youth in the United States. Yet evidence-based prevention programming is limited due to the rapid onset of this threat. Community-based efforts to address vaping largely target youth in school settings. Although parents can play an important role in youth tobacco control efforts, messages about the dangers of vaping, use among adolescents, and strategies for intervening have not reached many Spanish-speaking parents in low-income Latinx communities. Our community-academic team developed e-cigarette prevention programming for use by promotor/as de salud to address this unmet need.
Methods
During the 1-year project, the team worked closely with a Project Advisory Committee to: review existing evidenceinformed materials; conduct focus groups with parents, youth and promotor/as to guide program development; develop a curriculum to prepare promotor/as to educate low-literacy, Spanish-speaking parents about vaping; craft Spanish language resources for promotor/as to use in community education sessions; train 61 promotor/as to deliver the program; and support program delivery to 657 community members.
Results Focus groups with promotor/as and community members, key-informant interviews, and brief surveys informed program development and assessment. Community member feedback was essential to development of appropriate materials. Promotor/as demonstrated significant pre- to post- training increases in e-cigarette knowledge and confidence in delivering vaping prevention education. Community members demonstrated a mastery of basic e-cigarette concepts and expressed intention to discuss vaping with their children.
Conclusions
Promotor/a-led programming for parents represents a promising approach to vaping prevention and control in the Latinx community.En ligne : https://doi.org/10.1007/s10552-023-01796-7 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10267 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] sevrage tabagique:méthode de sevrageIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : BACKGROUND:
A large number of adolescent e-cigarette users intend to quit vaping or have past-year abstract quit attempts. However, it remains unknown which methods they use in their vaping cessation efforts.
METHODS:
We analyzed current (past 30-day) e-cigarette users who made $1 quit attempt in the past 12 months from the 2021 National Youth Tobacco Survey (NYTS) to examine the prevalence and associations of sociodemographic factors, vaping behaviors, and harm perception with the adoption of different vaping cessation methods.
RESULTS:
In the 2021 NYTS, there were 1436 current vapers, and 889 (67.9%) had made a pastyear quit attempt. Of those, 575 (63.7%) (weighted N 5 810 000) reported they did not use any resources (unassisted quitting). Peer support (14.2%), help on the Internet (6.4%), a mobile app or text messaging (5.9%), and parent support (5.8%) were the top 4 cessation methods.
Female (versus male) vapers were less likely to solicit parent support (adjusted odds ratio [AOR], 0.2; 95% confidence interval [95% CI], 0.1–0.5), whereas Hispanic (versus White)
vapers were more likely to seek friend support (AOR, 2.1; 95% CI, 1.1–3.9) and parent support (AOR, 2.7, 95% CI, 1.2–6.3). Those who perceived vaping to be harmful were less likely to get
friend support, but more likely to use a mobile app or text messaging program. Dual users of ecigarettes and any other tobacco product were more likely to get help from a teacher/coach or a
doctor/health care provider and treatment from medical facilities than sole e-cigarette users.
CONCLUSIONS:
There were different correlates with the adoption of vaping cessation methods, highlighting the need for tailored approaches to meet the cessation needs and preferences of the adolescent vaping population.En ligne : https://doi.org/10.1542/peds.2023-062948 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10278 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

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 !

système reproducteurIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : Abstract:
Electronic cigarettes (e-cigarettes) are often considered a “safe substitute” for conventional cigarette cessation. The composition of the fluid is not always clearly defined and shows a large variation within brands and manufacturers. More than 80 compounds were detected in liquids and aerosols. E-cigarettes contain nicotine, and the addition of flavorings increases the toxicity of e-cigarette vapour in a significant manner. The heat generated by the e-cigarette leads to the oxidation
and decomposition of its components, eventually forming harmful constituents in the inhaled vapour. The effects of these toxicants on male and female reproduction are well established in conventional cigarette smokers. Although toxins were measured at much lower levels in e-cigarette aerosols compared to smoke from a conventional cigarette, there are concerns about their potential impact on male and female reproduction. The information available was mainly obtained from studies conducted in animal models, and investigations in humans are scarce. However, the effects observed in animal models suggest that caution should be taken when vaping and that more research needs to be conducted to identify its potential adverse effects on fertility. The prevalence of e-cigarette usage is alarming, and warnings should be made about the impact of vaping on reproductive health.

[TABAC] chimie du tabac:tabac fumé:cigarette:cigarette électroniqueIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : Aims
To assess levels of nicotine, nicotine degradation products and some specific impurities in commercial refill liquids for electronic cigarettes.
Design and setting
We analyzed 20 models of 10 of the most popular brands of refill liquids, using gas and liquid chromatography.
Measurements
We assessed nicotine content, content of the known nicotine degradation products and impurities, and presence of ethylene glycol and diethylene glycol.
Findings
The nicotine content in the bottles corresponded closely to the labels on the bottles. The levels of nicotine degradation products represented 0–4.4% of those for nicotine, but for most samples the level was 1–2%. Cis-N-oxide, trans-N-oxide, myosmine, anatabine and anabasine were the most common additional compounds found. Neither ethylene glycol nor diethylene glycol were detected.
Conclusion
The nicotine content of electronic cigarette refill bottles is close to what is stated on the label. Impurities are detectable in several brands above the level set for nicotine products in the European Pharmacopoeia, but below the level where they would be likely to cause harm.En ligne : http://onlinelibrary.wiley.com/doi/10.1111/add.12235/abstract Format de la ressource électronique : HTML et PDF (payant) Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=7599 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] prévention:évaluationIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : This volume addresses the many issues surrounding electronic cigarettes in an unprecedented level of scientific detail. The plethora of product devices, formulations, and flavors, combined with the lack of industry standards and labeling requirements, quality control, and limited product oversight, has given rise to public concern about initiation of use and potential for adverse exposure and negative long-term health outcomes. This volume discusses how analytical methods can address these issues and support the manufacturing, labeling, distribution, testing, regulation, and monitoring for consistency of products with known chemical content and demonstrated performance characteristics.
The book begins with the background on aerosol drug delivery services and e-cigarettes, constituents of nicotine-containing liquid dosing formulations, typical use scenarios and associated aerosol emissions, and chemical exposures and pharmacological and toxicological effect profiles, and then continues with descriptions of the analytical methods used to characterize the chemicals in formulations and emissions from e-cigarettes, including their stability, physical particle-size distribution and thermal degradation under commonly employed conditions of use.
Analytical methods enabling detection of biomarkers of exposure and harm in complex biological matrices are discussed, with an emphasis on constituents or emissions of current medicinal interest or with potential to produce harm. Opportunities and challenges for analytical chemistry in supporting the continued development and use of safe and consistent dosage formulations as alternatives to tobacco products are also explored, with a concluding section describing an analytical approach to a risk-benefit assessment of e-cigarette use on human health.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=8103 Exemplaires (1)

[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] chimie du tabac:tabac fumé:cigarette:cigarette électroniqueIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : En réaction à l’augmentation du nombre de jeunes vapoteurs, Santé Canada a récemment proposé d’interdire la plupart des ingrédients aromatisants des liquides de vapotage.
Les données récoltées à San Francisco, où une interdiction de vente de liquides de vapotage aromatisés est en vigueur depuis 2018, montrent pourtant une recrudescence significative du nombre de jeunes ayant fumé la cigarette après l’instauration de cette mesure, ce qui soulève de sérieux doutes sur l’efficacité de cette approche.
De plus, l’interdiction des saveurs de vapotage va priver plusieurs milliers de fumeurs adultes du meilleur outil disponible pour cesser de fumer, tel que documenté par plusieurs études cliniques récentes.
Le projet d’éliminer du marché les saveurs de vapotage semble donc mal avisé et nous croyons que son application devrait être à tout le moins retardée en attendant de mieux déterminer ses impacts sur les taux de tabagisme, autant chez les jeunes que chez les adultes.
