Filter by:The purpose of the study is to determine if an Ask, Advise, Connect (AAC) intervention model benefits tobacco control outcomes for pediatric primary care providers (pPCP's) and their young patients.
The primary goal of this study is to examine whether cigarette smokers can reduce their use of conventional, combustible cigarettes by switching to a Standardized Research E-Cigarette (SREC); whether participants can maintain these reductions and use of SRECs over a 12-week period; and whether there are changes in subjective and objective measures of health, appeal and acceptability of the products used during this time frame.
This trial will examine the contribution of massage therapy and mindfulness to tobacco-smoking women in the third trimester of pregnancy.
This study will examine the effectiveness of a social norms campaign in correcting smoking misperceptions, reducing smoking susceptibility and changing smoking-related behaviours in Hong Kong adolescents.
The 2-year research plan will test the Put It Out Project (POP) in a pilot randomized trial (N=120) compared to TSP and two historical control conditions. Participants will be young adults who smoke, identify as sexual or gender minorities, and use Facebook. The 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 mos.
The current study aimed to test a culturally tailored program designed to help Pacific Islanders (PIs) between the ages of 18 and 30 quit smoking cigarettes by using a randomized controlled trial design with one intervention group and one control group.
The study aims to (1) evaluate the effectiveness of the recent renewal of tobacco health warnings (HWs) on noticing and anti-smoking responses, and (2) assess the effect of exposure to point-of-sale (POS) tobacco displays and smoking hotspots on nicotine-craving intensity and smoking-related behaviors. The study will use time-based system-triggered ecological momentary assessments to collect real-time data about exposures to smoking-related cues and behaviors. With a smartphone app installed in the mobile phones of the participants, they will each day complete at least 3 pairs of EMA prompted randomly for only 2 days (a working and a nonworking day). Outcomes include exposure and responses to tobacco HWs, exposure to POS tobacco displays, exposure to smoking hotspots and smoking and quitting outcomes.
Nicotine mediates smoking's addictive effects in the brain. The ratio of 3-hydroxycotinine to cotinine, known as the nicotine metabolite ratio, or NMR, is a genetically- informed biomarker reflecting hepatic CYP2A6 activity and the rate of nicotine metabolism. In light of a recent randomized controlled trial (RCT) in humans in Lancet Respiratory Medicine, which found that the NMR can be used to individualize treatment for smokers, our pilot study aims to determine the feasibility of using NMR to guide selection of pharmacotherapy in clinical populations of daily smokers.
This project aims to develop electroretinogram as a new putative marker for dopamine release, and as a predictor of treatment response among patients seeking treatment for smoking cessation. Tobacco smoking continues to be a major public health challenge. Dopamine is a neurotransmitter released in the brain. Several lines of evidence suggest that dopamine release deficit in the brain is involved in the development and maintenance of nicotine dependence. The investigators hypothesize that smokers who do not have a deficit in dopamine release will more readily respond to behavioral treatment for smoking cessation, and in particular, financial incentives contingent on abstinence (Contingency Management). Previous pilot data suggest electroretinogram (ERG), which records electrical signals from the retina in response to light, is a clinically accessible correlate to dopamine release in the brain. The project proposes an ERG-based biomarker, and a pilot clinical trial to apply this biomarker to personalize smoking cessation treatment. This clinically tractable biomarker of central dopamine release may have a large number of future applications in the diagnosis and treatment of other mental illnesses and substance use disorders. The study will recruit normal controls and smokers, measure ERG before and after a standard dose of oral immediate release methylphenidate. Smokers will undergo a 12-week standardized treatment course of CM. The investigators will test whether smoking status and the response to CM are correlated to changes in ERG in response to methylphenidate challenge.
The purpose of this study is to compare intensive telephone counseling (ITC) plus the nicotine patch vs. standard telephone counseling plus the nicotine patch (Usual Care; UC) among current smokers undergoing lung cancer screening. Smoking-related outcomes will be examined at three, six and twelve months post-randomization.
