Filter by:This randomized controlled trial aims to investigate the effect of an individually tailored lifestyle feedback letter and a leaflet on lifestyle in the context of sigmoidoscopy screening.
It has previously been shown that patients with coronary artery disease may have a harder time quitting smoking if they have a specific genetic profile and that these individuals have a better chance at quitting if they receive nicotine replacement therapy. The investigators hypothesize that determining which individuals with coronary artery disease should receive nicotine replacement therapy based on their genotype may improve the number of individuals who are able to quit smoking.This study randomizes treatment to that determined by the patient's genotype compared to standard, non-genotype-guided, treatment.
Pictorial cigarette warning labels (PWLs) are thought to increase risk knowledge, but experimental research has not examined PWLs' longer term effects on memory for health risks. This trial tests memory for health risks immediately or after a six-week delay for US-representative adult smokers, US-representative teen smokers/vulnerable smokers, and Appalachian-representative adult smokers. In addition, the trial tests the effects of different warning label components and the consequences of memory for labels on risk perceptions and quit intentions.
Smoking is the leading cause of avoidable death in the world. Smoking is associated with the development of cardiovascular and respiratory diseases, as well as being considered a leading cause of cancer death. Data show that smokers have increased cardiovascular risk in relation to former smokers, even in comparison with individuals who have had a long and intense history tobacco use. Considering this scenario, some drugs are used in tobacco cessation therapy. The first-line anti-smoking treatments approved by the Food and drug administration ( FDA ) are nicotinic reuptake therapy, bupropion ( norepinephrine and dopamine reuptake inhibitor) and varenicline ( partial agonist of nicotinic receptors composed of subunits alpha4Beta2 ). A metanalysis of 16 clinical studies indicated that smokers treated with bupropion had a higher abstinence rate compared to those receiving placebo - Odds ratio (OR ) - of 1,97 for treatment success. Varenicline is more effective compared to others smoking cessation drugs approved by the FDA, with an OR of 2,27 ( IC 95% 2,02-2,55 ) compared to placebo. However, Varenicline is much more expensive than bupropion. Significant advances in genetics have made the variability of the individual response to drugs, as far as efficacy as well as the rate of adverse effects, begin to be specifically investigated through pharmacogenetics studies.
All participants will receive free weekly counseling (8- weeks) and free nicotine patches (10-weeks). They will complete assessment measures commonly used in smoking cessation studies. We hope to show that this treatment is feasible in this small pilot study before comparing it to a more established treatment in a future randomized clinical trial.
The proposed study will use a factorial design to evaluate the most promising and accessible behavioral and pharmacologic treatments aimed at achieving maximal efficacy for smoking cessation among people living with HIV who smoke. The study will randomize 300 participants people living with HIV , who smoke and who are receiving care in HIV clinics affiliated with the Center for International Health, Education, and Biosecurity in Nairobi, Kenya to one of the following 4 conditions: (1) bupropion + Positively Smoke Free (an 8 session tailored behavioral intervention for people living with HIV smokers); (2) bupropion + Standard of Care (brief advice to quit); (3) Placebo + Positively Smoke Free; and (4) Placebo + Standard of Care.
The intervention to be studied is a smoking cessation program offered to newly diagnosed cancer patients at their first consultation for treatment at an oncological hospital department.
This study aims to investigate the benefit of administering two differing doses of Bupropion (BUP) to smokers to assist with smoking cessation.
The objectives of this pilot clinical trial are: 1) To evaluate the feasibility and acceptability of a new approach to smoking cessation induction treatment in cancer survivors with low social resources, and 2) To assess the effectiveness of said treatment for key events in the process of smoking cessation.
This study is to help determine the most effective type or combination of treatments to offer patients seeking lung cancer screening who are smokers to help them reduce the number of cigarettes they smoke, or quit smoking. The investigators long term goal is to increase the benefits of lung cancer screening by providing a blue print of best practices for screening sites to deliver tobacco treatment to their patients who are smokers, in a way that does not add burden to screening site staff and increases the chances of patients quitting smoking.
