Filter by:Particulate matter exposure during smoke inhalation provokes inflammatory immune responses in people exposed to burning biomass including fire fighters and civilians. Persistent occupational exposure to particulate matter represents a unique hazard for firefighters, underpinning a burgeoning research area. This trial will evaluate the effects of sleep deprivation and circadian rhythm disruption on the inflammatory response to woodsmoke associated particulate matter exposure. Participants will undergo 2 experimental trials in a randomized cross-over design. Participants will have either an 8-hour sleep opportunity or a 4-hour sleep opportunity prior to reporting to lab for a 45 minute simulated firefighting trial (wood smoke associated particulate matter filtered to 2.5 um at a concentration of 250 ug/m^3, while exercising at a moderate intensity). The effects of sleep restriction and simulated firefighting will be measured.
This study compares the health effects of dermal and inhalational exposure to thirdhand cigarette smoke to those of inhalational exposure to secondhand cigarette smoke in healthy, adult nonsmokers. Our hypothesis is that dermal exposure increases exposure to the tobacco specific carcinogen, NNK and may affect both endothelial function and epidermal integrity.
Since decades, literature has shown that smoking has negative effect on postoperative outcome. Recent systematic review and meta-analysis on clinical impact of smoking and smoking cessation showed that postoperative healing complications occur more often in smokers compared with nonsmokers. The use of electronic cigarette (e-cigarette) is spreading through the world. Despite this fact, the health risk assessment studies on e-cigarette are limited and scientific evidences are inconsistent. This prospective multicenter study aimed at assessing the use of e-cigarette whether patient undergoing elective surgery. The main objective of this study was to evaluate the prevalence of e-cigarette consumer in perioperative period. Secondary objectives were to analyze when patients consume e-cigarette in regard of surgery, how many dose they consume and if they also consume nicotine cigarette.
Almost everyone is aware these days is aware about the risk of smoking. Still many people start this habit specially in early life and during college year. We aim to investigate in this study if there is a drive to smoke in people with vasovagal tendency to improve their symptoms, even if not aware of this. Vasovoagal symptoms are common and include dizziness, smoking, sweating, abdominal pain, fatigue and syncope. Some studies have shown correlation between smoking and a positive tilt table test which is indicative of vasovagal tendency. By collecting the information regarding smoking habit and vasovagal symptoms analysis can be done to see if there is correlation between these two factors
