1. Youth and young adults who had never used tobacco were surveyed on exposure to electronic cigarette (e-cigarette) marketing and electronic nicotine delivery system use twice over 1-2 years. The majority of respondents reported past-30-day marketing exposure. 2. Youth exposed to e-cigarette marketing had significantly increased odds of having experimented...
1. The receipt of evidence-based treatment for nicotine use disorder is extremely low among adolescents and young adults. Evidence Rating Level: 2 (Good) It has now been well established that adolescents and young adults using e-cigarettes are at high risk of transitioning to combustible cigarettes. As such, it is important to...
Identification of patients and plaques vulnerable to future coronary events with near-infrared spectroscopy intravascular ultrasound imaging: a prospective, cohort study 1. NIRS imaging in patients undergoing cardiac catheterization for suspected coronary artery disease can be used in identifying high-risk non-culprit lesions contributing to future major adverse coronary events.  Evidence Rating Level:...
1. Youth (middle and high school students) and young adults (college students) who had never used electronic nicotine delivery systems (ENDS) but recalled exposure to ENDS marketing on baseline survey had higher odds of initiating ENDS use at 2.5-year follow-up, compared to those who did not recall marketing exposure. 2....
1. At 1 year, patients assigned to e-cigarettes for use in smoking cessation had a higher rate of smoking abstinence compared to those randomized to a nicotine-replacement group when accompanied by behavioral support. 2. Cough and phlegm production decreased from baseline to 1 year to a greater degree in the...
  1. A gene alteration in the nicotinic acetylcholine receptor (nAChR) α5 subunit, previously found to be associated with schizophrenia, was recapitulated in mice and led to increased neuron firing in the prefrontal cortex and reduced pyramidal cell activity. 2. Following the administration of nicotine, neuronal firing was normalized in mice deficient...
1. Former smokers who used only e-cigarettes or only nicotine replacement therapy (NRT) for ≥6 months (long-term) were found to have generally similar levels of nicotine but considerably reduced levels of measured carcinogens and toxins compared to users of combustible cigarettes (either solely or along with e-cigarettes or NRT). 2....
1. The American Academy of Pediatrics (AAP) states that exposure to electronic nicotine delivery systems (ENDS) such as electronic cigarettes (e-cigarettes) are dangerous to youth, including involuntary second or third-hand aerosol exposure. 2. Pediatricians should counsel against the use of and exposure to these products, and provide adequate resources for...
1. In this cross-sectional sample of high school students, 1 in 20 reported using electronic cigarettes (e-cigarettes) to vaporize cannabis. Among students who reported using cannabis in any form at least once, nearly 1 in 5 had used an e-cigarette to vaporize cannabis. 2. In these high school students, e-cigarette use...
In this section, we highlight the key high-impact studies, updates, and analyses published in medicine during the past week. Cytisine versus Nicotine for Smoking Cessation When compared with placebo, cytisine, a partial nicotinic acetylcholine receptor agonist, has been shown to nearly double the chance of smoking cessation at 6 months. This...
