RESUMO
BACKGROUND: Recently, electronic cigarette (e-cig) usage has increased significantly, making it a potentially effective smoking cessation tool. In Muslim countries, most people who use e-cigarettes fast the month of Ramadan, which results in intermittent fasting. This study aims to reveal the severity of e-cig withdrawal symptoms among users during this intermittent fasting period. METHODS: A self-administered survey was developed and validated to solicit anonymous responses from e-cig users living in Jordan, through a cross-sectional study design. Participants were recruited through social media resources. Severity scores of physical (out of 11) and psychological (out of 8) withdrawal symptoms for each participant were assessed and calculated for each participant, depending on the symptoms reported. RESULTS: A convenience sample (n = 523) of e-cig adult users were recruited. The majority of the participants were males (96.4%) aged between 18 and 40 years (86.4%). Many participants replaced tobacco smoking with e-cig (53.5%) in order to help them stop smoking. More than half of the participants experienced relatively weak physical (0.82 ± 1.78) and psychological (1.24 ± 1.89) withdrawal symptoms during the month of fasting. Most of the participants (63.2%) preferred to engage themselves with a busy schedule to tolerate the related withdrawal symptoms they experienced. CONCLUSION: E-cigs could play a vital role in smoking cessation among tobacco smokers during intermittent fasting. Ramadan offers a good opportunity for smokers to quit, as the reported physical and psychological e-cig withdrawal symptoms were found to be relatively weak. Awareness and behavioral interventions would help clarify the effect of e-cigs and help determine alternative ways to cease smoking.

Lipopolysaccharide (LPS) is an endotoxin composed of a polysaccharide and lipid component. It is intrinsically responsible for the pathogenicity of Gram-negative bacteria and is involved in the development of bacterial sepsis. Atmospheric pressure non-thermal plasma is proposed as a potential new approach for the treatment of infected tissue such as chronic wounds, with both antibacterial and wound-healing activities extensively described. Using both the RAW264.7 murine macrophage cell line in vitro assays and the Galleria mellonella insect in vivo toxicity model, the effect non-thermal plasma exposure on LPS-mediated toxicity has been characterised. Short (60 s) non-thermal plasma exposures of Pseudomonas aeruginosa conditioned growth media, membrane lysates and purified P. aeruginosa LPS, resulted in a substantial detoxification and reduction of LPS-induced cytotoxicity in RAW264.7 murine macrophages. Non-thermal plasma exposure (60â¯s) of purified P. aeruginosa LPS led to a significant (pâ¯<â¯0.05) improvement in the G. mellonella health index (GHI) score, a measure of in vivo toxicity. These findings demonstrate the ability of short plasma exposures to significantly reduce LPS-induced cytotoxicity both in vitro and in vivo; attenuating the toxicity of this important virulence factor intrinsic to the pathogenicity of Gram-negative bacteria.
