RESUMO

There is limited information about what dental students know about the risks and effects of e-cigarettes, and there is even less information regarding their attitudes about e-cigarettes. The aim of this study was to assess dental students' knowledge, education, and attitudes regarding e-cigarettes and their confidence in discussing e-cigarettes with patients. All fourth- to sixth-year students registered at the King Abdulaziz University Faculty of Dentistry were invited to participate in this cross-sectional study conducted during a three-week period in December 2018. The focus was a comparison of never versus ever e-smokers ("ever" meaning current or former e-smokers). The response rate was 38.7% (193/498). Among the responding students, 43.2% (n=83) had ever used an e-cigarette, and 11 (5.7%) reported being current users. Almost 95% (n=183) of the total participants said they did not feel confident about their e-cigarette education in dental school. Students who had ever used an e-cigarette said they were more confident discussing e-cigarettes with patients than did students who had never used them and also demonstrated greater belief that e-cigarettes lower the risk of cancer for patients who use them as an alternative to smoking traditional cigarettes (p<0.001). This study provides evidence of a gap in dental students' attitudes and knowledge regarding e-cigarettes, making it necessary to integrate e-cigarette education into future curricula.

RESUMO

In 2019, the United States experienced an outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). Most EVALI patients have reported using tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, products obtained from informal sources (2,3), and vitamin E acetate in these products has been closely linked with EVALI (4,5). However, some EVALI patients report using only nicotine-containing products. This study compared demographic, product use, and clinical characteristics of EVALI patients in Illinois who reported using only nicotine-containing e-cigarette, or vaping, products with those of patients who reported using any THC-containing products. Among 121 interviewed Illinois EVALI patients, 17 (14%) reported using only nicotine-containing products, including nine (7%) patients who had no indication of any THC use, based on self-report or toxicology testing. Compared with patients who used any THC-containing products, these nine patients were significantly more likely to be older and female and were less likely to experience constitutional symptoms or to have leukocytosis on initial evaluation. Although vitamin E acetate has been strongly linked with EVALI, evidence is not sufficient to rule out the contribution of other chemicals of concern, including chemicals in either THC- or non-THC-containing products, in some reported EVALI cases. The contributing cause or causes of EVALI for patients reporting use of only nicotine-containing products warrants further investigation.

RESUMO

Since August 2019, CDC, the Food and Drug Administration (FDA), state and local health departments, and public health and clinical stakeholders have been investigating a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). This report updates patient demographic characteristics, self-reported substance use, and hospitalization dates for EVALI patients reported to CDC by states, as well as the distribution of emergency department (ED) visits related to e-cigarette, or vaping, products analyzed through the National Syndromic Surveillance Program (NSSP). As of January 14, 2020, a total of 2,668 hospitalized EVALI cases had been reported to CDC. Median patient age was 24 years, and 66% were male. Overall, 82% of EVALI patients reported using any tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, product (including 33% with exclusive THC-containing product use), and 57% of EVALI patients reported using any nicotine-containing product (including 14% with exclusive nicotine-containing product use). Syndromic surveillance indicates that ED visits related to e-cigarette, or vaping, products continue to decline after sharply increasing in August 2019 and peaking in September 2019. Clinicians and public health practitioners should remain vigilant for new EVALI cases. CDC recommends that persons not use THC-containing e-cigarette, or vaping, products, especially those acquired from informal sources such as friends, family members, or from in-person or online dealers. Vitamin E acetate is strongly linked to the EVALI outbreak and should not be added to any e-cigarette, or vaping, products (2). However, evidence is not sufficient to rule out the contribution of other chemicals of concern, including chemicals in either THC- or non-THC-containing products, in some reported EVALI cases.

RESUMO

CDC, the Food and Drug Administration (FDA), state and local health departments, and public health and clinical stakeholders continue to investigate a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). EVALI patients in Illinois, Utah, and Wisconsin acquired tetrahydrocannabinol (THC)-containing products primarily from informal sources (2,3). This report updates demographic characteristics and self-reported sources of THC- and nicotine-containing e-cigarette, or vaping, products derived from EVALI patient data reported to CDC by state health departments. As of January 7, 2020, among 1,979 (76%) patients with available data on substance use, a total of 1,620 (82%) reported using any THC-containing products, including 665 (34%) who reported exclusive THC-containing product use. Use of any nicotine-containing products was reported by 1,128 (57%) patients, including 264 (13%) who reported exclusive nicotine-containing product use. Among 809 (50%) patients reporting data on the source of THC-containing products, 131 (16%) reported acquiring their products from only commercial sources (i.e., recreational dispensaries, medical dispensaries, or both; vape or smoke shops; stores; and pop-up shops), 627 (78%) from only informal sources (i.e., friends, family, in-person or online dealers, or other sources), and 51 (6%) from both types of sources. Among 613 (54%) EVALI patients reporting nicotine-containing product use with available data on product source, 421 (69%) reported acquiring their products from only commercial sources, 103 (17%) from only informal sources, and 89 (15%) from both types of sources. Adolescents aged 13-17 years were more likely to acquire both THC- and nicotine-containing products from informal sources than were persons in older age groups. The high prevalence of acquisition of THC-containing products from informal sources by EVALI patients reinforces CDC's recommendation to not use e-cigarette, or vaping, products that contain THC, especially those acquired from informal sources. Although acquisition of nicotine-containing products through informal sources was not common overall, it was common among persons aged <18 years. While the investigation continues, CDC recommends that the best way for persons to ensure that they are not at risk is to consider refraining from the use of all e-cigarette, or vaping, products.

RESUMO

AIM: The aim was to investigate whether e-cigarette use predicts later experimentation with conventional cigarettes. METHODS: During the 2016/2017 school year, 2,388 children and adolescents from Baden-Württemberg, Mecklenburg-Western Pomerania, North Rhine-Westphalia, Rhineland-Palatinate, Schleswig-Holstein and Saxony who had never smoked conventional cigarettes before took part in a survey over a 2-year period (mean age 11.8 years, SD = 1.21; 49.6 % female). RESULTS: At baseline, 85 pupils (3.6 %) reported that they had already tried e-cigarettes at least once. By the end of the observational period, 430 of the sample had tried conventional cigarettes (18.0 %). After statistical control for age, sex, migration background, type of school, socioeconomic status, sensation-seeking, alcohol use, and school performance, the adjusted relative risk of experimentation with conventional cigarettes was 85 % higher (adjusted relative risk = 1.85, 95 % CI [1.34 - 2.56]) for pupils who had used e-cigarettes at baseline. Further analyses revealed that the risk was higher among adolescents with low sensation-seeking scores. CONCLUSION: Among young never-smokers, experimentation with conventional cigarettes is more common in those who used e-cigarettes before than among those who have not tried e-cigarettes before. This effect seems to be stronger among adolescents who, in general, have a lower risk of starting to smoke.

RESUMO

Compared with children exposed to traditional cigarettes, those exposed to nicotine in e-cigarettes are 5.2 times more likely to be admitted to a healthcare facility and have 2.6 times the risk of a severe outcome. This article discusses nicotine toxicity in children accidentally exposed to e-cigarettes containing nicotine and reviews appropriate nursing interventions.

RESUMO

Vaping has recently gained popularity among teenagers and young adults, well beyond its scope as an alterna- tive to cigarette smoking. A perceived favorable safety profile may have stemmed from the fact that vaping is being evaluated as a smoking cessation tool. We present a case of a young adult non-smoker who was exposed to commercially available vaping, and socially available cannabinoid by vaporizer, one to two weeks prior to developing respiratory and constitutional symptoms. His work-up confirmed a case of vaping induced lung injury.
