Filter by:Tobacco use is the single greatest preventable cause of morbidity and mortality in Canada, accounting for 48,000 deaths and $16.2 billion annually in attributable health-related costs. Parents who smoke are often medically underserved and visit their child's doctor more than their own; 25% of all adult smokers have children seen in child healthcare. When parents quit smoking, their life expectancy is increased by more than 10 years, tobacco-related poor pregnancy outcomes are eliminated, children's risk of becoming smokers decreases 4-fold, families have more money for necessities, and children are less likely to suffer from diseases caused by tobacco smoke exposure. Despite free tobacco cessation services in every province and widespread insurance coverage of NRT, parental tobacco screening and cessation support rarely happens in pediatric care, thus there is potential for major health benefits from a routinely delivered tobacco control program to parents in this setting. The investigators will conduct a 12-month single centre, pragmatic, single-blind pilot RCT of CEASE vs. usual care of 70 parents who use cigarettes and/or vaping products whose children are seen in pediatric clinics at the CHU Sainte-Justine. A similar trial, CEASE-A will be conducted with 70 adolescents ages 14-17. Objectives: 1. Perform a pilot RCT of the Clinical Effort Against Secondhand Smoke (CEASE) intervention in Canada. CEASE is an evidence-based parental smoking cessation intervention to ensure that every parent who uses cigarettes and/or nicotine vaping products and visits their child's pediatrician receives nicotine dependence treatment 2. Conduct an ancillary pilot RCT of CEASE-A to deliver evidence-based support for adolescents who use tobacco and/or nicotine vaping products Outcomes include pilot process outcomes and preliminary effectiveness outcomes to assess feasibility and inform the preparation of a future large-scale RCT. This pilot RCT will provide the data necessary to plan a fully powered RCT assessing the effectiveness of CEASE and CEASE-A for smoking and vaping cessation.
The prevalence of smoking in the homeless population (70%) is over 4 times that of the general population (15%). Homeless adults have not experienced similar declines in tobacco use as the general population has over the past three decades. Homeless adults are interested in smoking cessation and make quit attempts, but are less successful in quitting smoking than the general population. Trials of group behavioral counseling and pharmacotherapy for smoking cessation have not led to substantial long-term abstinence (i.e., abstinence for 6 months or more), suggesting that these interventions alone are insufficient to improve quit rates among homeless adults. Many homeless adults seek health care in safety net clinics; these clinics could bring cessation interventions to scale. Contingency management is a powerful behavior change intervention that reinforces positive health behaviors through the provision of modest incentives (e.g., cash). In this pilot randomized controlled trial, the investigator will test the feasibility and acceptability of a contingency management intervention that provides incentives for smoking cessation for people experiencing homelessness.
This is a research study, is testing a program to improve lung health through smoking cessation and providing education around lung screening. In this research study involves Studying the Enhanced Smoking Cessation Approaches to Promote Empowerment (ESCAPE) program compared to usual care. The ESCAPE program was developed help women with HIV quit smoking. Women in the ESCAPE program quit smoking and stayed quit for longer (up to 3 months). For this study, investigators have added a lung screening to the ESCAPE program and want to test if this will improve lung health through increasing quit rates and lung screening. .
To explore the impact on genetic and environmental factors for clinical manifestation, and the progression of chronic pancreatitis, including development of pancreatic insufficiency and other complications.
Physically healthy adult smokers may be eligible for this study. Volunteers may participate in this study if they are 18 - 65 years old. Subjects will participate in two separate 7-hour PET/CT Scan Sessions (each with 2 hours of actual PET/CT scanning): one following an overnight abstinence and one following two overnights of abstinence. To achieve and confirm two overnights of abstinence, participants will present to the inpatient CHPS the day prior to the scheduled scan and stay overnight. The 2-[18F]-FA PET/CT brain scans will consist of an injection followed by an 7-hour infusion of 2-[18F]-FA. The scan session will begin at approximately 4 hours after the bolus injection. The PET/CT scan will occur in two segments. Starting at approximately 4 hours post bolus and infusion start, we will scan for approximately 90 minutes with a bolus injection of IV nicotine that will occur approximately 15 minutes into the scanning procedure. There will be a break in scanning of approximately 60 minutes, during which subjects will be allowed to get off the scanner and use the restroom, if necessary. The second scan segment will start at approximately 6.5 hours post bolus injection, t. This segment will last approximately 30 minutes. The pre and post nicotine images will be analyzed to evaluate for differences in receptor uptake after the nicotine "challenge". Subjects will have a structural Brain MRI performed within 1 year prior to study enrollment or subjects who have not had a Brain MRI that is deemed acceptable for use for this study will undergo a research Brain MRI after consent.
The aim of these studies is to adapt the self-affirmation kindness questionnaire for use in a mobile application. Two studies will be conducted to test hypotheses that simplifying and shortening the original questionnaire in systematic ways will result in comparable effectiveness (compared to the original version) in promoting reduced defensive avoidance, less reactance, greater yielding, and higher intentions to quit smoking among a sample of smokers.
