Abstract Though e-cigarette aerosol has been associated with altered lung cell function, few studies have examined the effects of use on immune response and respiratory symptoms. The purpose of this study was to examine if recent persistent cough or cytokine levels are related to Electronic Nicotine Delivery Systems (ENDS) use in college students. In April 2019, 61 undergraduate students at the University of Kentucky completed surveys and provided a salivary sample to evaluate cytokine levels (Interleukin (IL-) 2, 4, 6, 8, 10, 12, 13 and TNFα, INFγ), using quota sampling to obtain comparable numbers of ENDS users and non-ENDS users. Data analysis included chi-square tests and multivariable logistic and linear regression. All ENDS users reported JUUL as their primary product. ENDS users were more likely to be younger, use cigarettes and marijuana, and report a persistent cough. Controlling for cigarette and marijuana use, there was a trend toward greater likelihood of persistent cough among ENDS users. Compared with nonusers, salivary IL-2 and INFγ were elevated and IL-4 was decreased, controlling for cigarette and marijuana use. There was a trend toward lower IL-12p70 values among ENDS users with these covariates. Findings reveal dysregulation of salivary immune profiles toward a TH1 phenotype in emerging adult ENDS users and short-term immune function may be dysregulated in young adult e-cigarette users.

Abstract Purpose The purpose of this study was to compare characteristics of usual JUUL users versus other electronic nicotine delivery systems (ENDS) users, examine differences in reasons for use and perceptions across ENDS user groups, and identify significant correlates of usual JUUL use. Methods This study used data from 510 young adult ENDS users (ages 18–29 years) from Wave 7 (Spring 2018) of the Marketing and Promotions Across Colleges in Texas Project (Project M-PACT). Chi-Square analyse...

Objective To estimate the prevalence of JUUL use and identify demographic and psychosocial correlates of use among youth and young adults in the USA. Methods A national, probability-based sample was recruited via address-based sampling, with subsamples recruited from an existing probability-based online panel. Participants (N=14 379) ages 15–34 were surveyed about JUUL use, tobacco use, electronic nicotine delivery system (ENDS) harm perceptions, sensation seeking and demographic characteristics...

Electronic cigarettes, handheld devices that generate an aerosol that may contain nicotine by heating a solution or e-liquid, have been increasingly used especially in the young population. The aerosol’s composition is determined by temperature, and by the substances contained in the heated liquid: glycerin, propylene glycol, nicotine in variable concentrations, flavoring agents, and other non-nicotine compounds. >80 compounds (including known toxics, e.g., formaldehyde, acetaldehyde, metallic n...

ABSTRACTIntroduction: Use of electronic cigarettes (e-cigarettes) is frequently promoted as a less harmful alternative to cigarette smoking. The impact of repeated inhalation of e-cigarette aerosols on respiratory health is not well understood.Areas covered: Using results from laboratory, observational, and clinical studies, we synthesize evidence relevant to potential respiratory health effects that may result from inhalation of e-cigarette aerosols.Expert commentary: Chemical analyses reveal t...

In recent years, use of electronic nicotine delivery systems (ENDS) has drastically increased, exceeding the prevalence of combustible tobacco use among youth in the USA.1 ENDS products are heavily marketed on television, radio and the internet, in print and at the point-of-sale,2–5 using strategies that may appeal to youth.6 Recent national data suggest exposure to ENDS marketing may be associated with increased use of the products among young people.5 7 Of public health concern are the finding...

Abstract Rhodococcus equi is a common cause of pneumonia in foals and an opportunistic pathogen in immunosuppressed people. The ability of R. equi to survive and replicate in macrophages is the basis of its pathogenicity. Limited knowledge about the role of cytokines in host defense against R. equi comes from studies in mice and the role of cytokines in intracellular survival of R. equi in equine macrophages is unknown. The objectives of this study were to determine the effect of priming with in...

E-cigarette vapour contains free radicals with the potential to induce oxidative stress. Since oxidative stress in airway cells increases platelet-activating factor receptor (PAFR) expression, and PAFR is co-opted by pneumococci to adhere to host cells, we hypothesised that E-cigarette vapour increases pneumococcal adhesion to airway cells. Nasal epithelial PAFR was assessed in non-vaping controls, and in adults before and after 5 min of vaping. We determined the effect of vapour on oxidative st...

Despite high rates of use of both cannabis and electronic nicotine delivery systems (ENDS), little is known about the role of cannabis use among ENDS users and of ENDS use among cannabis users. This study tested whether dual use was related to more frequent use, use-related problems, and negative affect. Among cannabis users (n=315), ENDS was associated with more frequent cannabis use, cannabis-related problems, anxiety, and depression. Among ENDS users (n=156), cannabis was associated with more...
