Filter by:The purpose of this research is to measure the extent of lung inflammation between different groups of participants using a radioactive tracer called [18F]NOS. A radioactive tracer is a type of imaging drug that is labeled with a radioactive tag and injected into the body.
The prevalence of smoking among US adults is highest among American Indians and Alaska Native (AI/AN) persons; however, there are a lack of tobacco cessation interventions developed specific to this disparity group. Social media holds promise as a scalable intervention strategy to promote engagement in treatment and cessation outcomes for Alaska Native (AN) people. Researchers plan to develop and pilot test a culturally relevant, Facebook delivered intervention to promote smoking treatment uptake and cessation among AN smokers. The Facebook content will include a digital storytelling approach adapted from the effective Centers for Disease Control (CDC) Tips from Former Smokers educational mass media campaign. The project builds on the researcher team's longstanding tobacco control research partnership with the AN community and was informed by their understanding of cultural factors that can both impede and encourage cessation in this population. If the pilot intervention is successful, researchers will have a blueprint to conduct a large randomized controlled trial. The researchers long-term objective is to develop interventions for AN tobacco users that will ultimately reduce their risk of tobacco-caused disease and mortality.
1. Understanding the smoking change patterns among the newly diagnosis lung cancer patients after cancer diagnosis. 2. Explore the related factors of the smoking change patterns. 3. The type of smoking trajectory impact on survival and quality of life.
Background: Electronic cigarettes (EC) mainly containing nicotine (88-95 % of users) are widely and growingly used worldwide. It is estimated that there were 1.7 million daily users in France in 2016. Although the number of publications about its use is increasing exponentially, there are no evidence based, unbiased, head-to-head comparison data about its efficacy as an aid to smoking cessation. As of today, only two head-to-head randomized studies have been published, both reported negative results at the main endpoint but they used first and second generation EC delivering nicotine with low or unknown bioavailability. Recent EC deliver nicotine with largely improved bioavailability. One of the randomized studies compared EC with and without nicotine to nicotine patch and reported similar smoking cessation rate at main outcome. However, there is no published, double blind study comparing EC use with a well-studied, licensed smoking cessation medication. Superiority of EC with nicotine compared to EC without nicotine and to a reference smoking cessation medication while collecting also straightforward information about safety, would allow proposing EC with nicotine to the large population of smokers who intend to quit and situate it among the approved smoking cessation treatments. The clinical study's hypothesis: EC containing nicotine can be considered as a nicotine replacement therapy having, probably, a better bioavailability of nicotine than the marketed pharmaceutical NRTs, first line medications of smoking cessation. It is therefore of interest to compare EC containing nicotine to EC without nicotine but also to a reference medication with demonstrated efficacy in smoking cessation. We hypothesize that EC with nicotine provides a higher smoking abstinence rate than EC without nicotine and may be as good as varenicline, our reference medication.
This study is being done to develop new methods to help smokers with schizophrenia to successfully reduce their smoking and/or quit. This is not a treatment study, but will help find new techniques to create better treatments. Specifically, the investigators are interested in learning more about how thoughts and attention problems associated with schizophrenia might play a role in smoking, as well as the impact of cognitive (thinking, reasoning, and remembering) training and brain stimulation on these symptoms and on actual smoking.
Prior and recent evidence suggests a role of medial prefrontal cortex (MPFC) in cigarette smoking. Episodic Future Thinking (EFT) has also been shown to be associated with increased delayed discounting and reduced cigarette self administration. In the present study, we will examine whether a single administration of theta-burst transcranial magnetic stimulation (tbTMS) can increase Episodic Future Thinking and delayed discounting while reducing craving for nicotine.
Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.
This is a 12-weeks, open label, non-inferiority trial comparing HTPs vs ECs in terms of efficacy, adoption rate and acceptability, tolerability, and tobacco harm reduction in 220 healthy smokers, not motivated to quit, randomized (1:1) to switch to one of these products. The duration of the study, from the enrollment to the study close out for all the patients at week 24 (follow-up), will be approximately 12 months. Enrollment period will last about 6 months with the support of a multi-channel advertising method. This will include location-based advertising on social networks, advertising in local media, information days organized within the city.
The 2-year research plan will test the Extended Put It Out Project (POP-6) in a pilot randomized trial (N=168) compared to TSP-6, as well as comparing POP-6 and TSP-6 to the POP-3 and TSP-3 interventions from a previously-conducted trial. Participants will be young adults who smoke, identify as sexual or gender minorities (SGM), and use Facebook. Primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be a quit attempt (y/n), stage of change, and thoughts about tobacco abstinence at 3 and 6 months.
Grip&Health: randomised trial which will examine the effect of theory-based multicomponent behavioural intervention for reducing stress, smoking and improving financial health and perceived health of low-SES residents in Rotterdam. Between January 2018 and July 2018, a total of 300 participants will be recruited and randomised either to a stress management program (SM), stress management with a buddy program (SM-B) or a control condition. The investigators hypothesise that compared to participants in the control condition, participants in the intervention arms will demonstrate reduced stress, reduced smoking and improved financial health and perceived health.
