Before the coronavirus disease 2019 (COVID-19) pandemic, vaping-related illness was the prevailing public health concern. The incidence of vaping-related illnesses-mainly e-cigarette, or vaping, product use-associated lung injury (EVALI)-went from a peak in September 2019 to a low in February 2020, and the Centers for Disease Control and Prevention decided to discontinue the collection of EVALI case reports. Despite the decrease in EVALI with the arrival of COVID-19, EVALI should still be considered a differential diagnosis for people with COVID-19 for reasons outlined in this review.
The disruption of glucose homeostasis associated with the use of nicotine delivery systems may be due to a shift to lipid metabolism. Indirect calorimetry was used to measure the respiratory exchange ratio (RER) in female (N = 21) and male (N = 21) C57BL/6J mice exposed to room air (control) or e-cigarette vapor in a 1L chamber to test the hypothesis that lipid metabolism predominates in vaped mice.
Since their market launch in 2007, e-cigarettes gained popularity and were considered a relatively safe alternative to traditional cigarettes.
Using data from 38 states in the United States, we showed geographical variations in the prevalence of e-cigarette use before and during pregnancy. Among women who used e-cigarettes before pregnancy, a quarter of them continued to use e-cigarettes during pregnancy. Conventional cigarette use is a strong risk factor for e-cigarette use before and during pregnancy. The prevalence of e-cigarette use needs to be monitored continuously.
Electronic cigarette (e-cigarette) harm perceptions and information seeking behaviours are both important antecedents of e-cigarette use, yet the relationship between them has been rarely studied. We assessed how absolute (e-cigarettes are harmful to my health) and relative harm perceptions (e-cigarettes are more/less harmful than cigarettes) were associated with specific e-cigarette information seeking behaviours in a sample of current, former and never cigarette smokers.
This study provides pre-clinical data implicating that electronic cigarette exposure is not safe in COPD patients who want to replace traditional cigarettes with ENDS.
EC also seems to worsen asthma symptoms and the rate and severity of exacerbations in asthmatics who are current vapers, whilst evidence suggests that its effectiveness as a smoking cessation tool might be limited. Asthmatic patients should avoid using EC.
ECIG aerosol exposure impaired functional memory and elicited changes in brain chemistry that are consistent with reduced function and oxidative stress.
