Filter by:The purpose of this study is to evaluate how nicotine, withdrawal from nicotine, and methylphenidate (a drug used for the treatment of ADHD) affect the brain of smokers with and without ADHD while doing tasks in an functional Magnetic Resonance Imaging scanner. Study Hypotheses: 1. compared to non-ADHD smokers, smokers with ADHD will exhibit greater abstinence-induced decrements in response inhibition performance and reward and greater concomitant disruptions of brain activity 2. administration of MPH to abstinent smokers will ameliorate response inhibition performance and reward deficits and task-related brain activation and this effect will be greater among ADHD smokers 3. genetic markers of dopamine neurotransmission will moderate abstinence- and MPH - induced changes in task-related brain activation across tasks.
At any given point in time, most smokers are not interested in making a serious quit attempt. Data suggest that 30% of smokers have no plans to quit, 30% plan to quit at some future date, 30% plan to quit in the next 6 months, and about 10% plan to quit in the next month. While ~40% of smokers make a quit attempt each year, only about 4-6% of those achieve long-term success. This means that of the more than 60 million Americans who smoke, only 1 million are able to quit each year. If we could double the number of quit attempts and maintain comparable success rates, we could double the number of individuals who will benefit from living smoke free lives. These observations underscore the need to develop interventions that increase smokers' motivation or willingness to make quit attempts, and that also increase the rate of success among those who attempt to quit. The overall goal of this proposed experiment is to identify effective interventions aimed at increasing motivation for smoking cessation, increasing quit attempts, and increasing rates of cessation success. Interventions that will be tested include: use of nicotine gum, use of nicotine patches, motivational interviewing, and smoking reduction counseling. At minimum, all participants will complete surveys about their smoking behavior that might increase their motivation to eventually quitting smoking.
Many smokers fail to take their smoking cessation medication as recommended. This research is designed to identify treatments that improve the use of cessation medications and to determine whether an increase in medication use results in increased cessation success. This research will also identify treatments that help people stay quit after a quit attempt and will pioneer more efficient research methods.
The goal of this study is to train phone counselors working for the New York (NY) State Smokers' Quitline to advise callers who drink at hazardous levels to limit or abstain from alcohol use to determine whether this improves smoking cessation outcomes so that we can establish effect size estimates for a full scale multi-site trial.
The goal of this research is to identify the best smoking cessation intervention components to be combined into a state-on-the-art, comprehensive smoking cessation intervention. This research examines the ability of different interventions, provided both prior to and after the quit attempt, to maximize the ability to initially quit and then stay quit. The investigators will be examining six different treatment interventions: pre-quit nicotine patch, pre-quit nicotine gum, pre-quit counseling, post-quit in-person counseling, post-quit phone counseling and duration of post-quit nicotine replacement therapy.
The purpose of this study is to determine whether an intensive, eight session behavioral intervention is superior to standard care in achieving abstinence from cigarettes in smokers living with HIV/AIDS.
Nicotine patches are frequently used in smoking patients during their stay in the ICU in order to avoid tobacco's weaning symptoms which are likely to interfere with mechanical ventilation weaning. Until now the effectiveness of this treatment has not been proven. The aim of this study (NICOREA study) is to determine if a difference exists on the duration of mechanical ventilation once patients receive or not a nicotine substitute.
The purpose of the study is to investigate the effectiveness of a smoking cessation intervention delivered through a technological web based platform (www.slutta.no) with or without a supportive SMS function.
Research shows that smoking cessation is the most significant preventable health behavior change that a person can make to lower cancer risk. In addition, telephone quitlines are an effective, science-based smoking cessation treatment that is universally accessible to smokers in the U.S. However, little research has explored promising approaches that could increase quitline use, improve quit rates, and inform resource allocation for quitline services. The proposed study will test three promising enhancements to the standard quitline treatment that typically consists of counseling and, possibly 2 weeks of a NRT medication. These enhancements are: 1) combination nicotine replacement therapy as recommended by the United States Public Health Service Clinical Practice Guideline on Treating Tobacco Use and Dependence; 2) extended duration of cessation medication use; and 3) an innovative counseling addition - cognitive medication adherence counseling - to optimize adherence to cessation medication. In addition, the cost-effectiveness of each intervention will be calculated. The findings of the proposed research have broad potential application and relevance to state quitlines, quitline service providers, and other purchasers of quitline services such as employers and insurers. Additionally, the study findings can potentially inform other telephone health behavior counseling programs.
The purpose of this community-based study is to evaluate the effectiveness of a culturally-tailored smoking cessation treatment for American Indian (AI) smokers as compared to standard evidence-based cessation treatment (not culturally-tailored).
