Filter by:RATIONALE: Collecting and storing samples of sputum and tissue to study in the laboratory may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking samples of sputum and tissue from lung cancer patients, participants at high risk for developing lung cancer, and from healthy volunteers (both smokers and non-smokers).
We plan to examine the feasibility, acceptability, preliminary quit rates, overall nicotine exposure and adverse effects of the nicotine inhaler for smoking cessation in pregnancy.
RATIONALE: A computer-assisted stop-smoking program may help doctors counsel patients who smoke and may help increase the number of patients who stop smoking. PURPOSE: This phase II trial is studying how well a computer-assisted stop-smoking program works in helping doctors counsel patients who smoke cigarettes.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of phenethyl isothiocyanate may prevent lung cancer in people who smoke cigarettes. PURPOSE: This randomized clinical trial is studying phenethyl isothiocyanate to see how well it works in preventing lung cancer in smokers.
Dopamine (DA) plays a critical role in nicotine (and other) addiction and this drug is known to release DA in brain areas mediating reward and motivational processes. Although imaging studies show that release of DA follows smoking, little is known regarding how common genetic polymorphisms for three genes associated in some studies with smoking (dopamine D2 receptor, dopamine and serotonin transporter) interact with smoking status and modulate individual differences in nicotine-induced DA release and dopamine receptor occupancy, in vivo. The current proposal combines brain imaging and genomics ('imaging genomics') towards partially unraveling the complex relationship between smoking phenotype and common polymorphisms. Understanding whether genetic factors contribute to inter-individual variability in smoking is crucial for interpreting imaging results in the context of disease pathology. We hypothesize that a model of vulnerability to addiction based on interactions between genotype, receptor and transporter availability and in vivo nicotine-induced DA release will elucidate some of the fundamental neurochemical and neurogenetic circuits underlying addiction.
The investigators want to find out if providing a Community Health Educator Referral Liaison (CHERL) helps practices help their patients change risky behaviors (tobacco use, physical inactivity, unhealthy diet, and risky drinking) by connecting patients to available services in the community or directly providing behavior change support.
Little is known about the best ways to help young people stop smoking. Bupropion (a medication marketed as Wellbutrin or Zyban) has proved helpful in treating adult smokers. The purpose of this study is to determine if bupropion is also effective in treating smokers between the ages of 12 and 25 years old. This study also compares the effectiveness of bupropion used as a supplement to behavioral treatment versus behavioral treatment used alone. In addition, the study evaluates whether hormonal response to stress measured prior to the start of treatment predicts whether individuals respond well to treatment with medication.
The purpose of this study is to determine whether a specialized, technology-based training program in tobacco prevention is more effective than standard training for pediatric residents who counsel youth and their parents.
