Filter by:This research aims to identify efficacious strategies for treating tobacco dependence among adolescent smokers with co-occurring psychiatric disorders. Adolescent smoking remains a significant public health issue with 23% of high school students reporting smoking a cigarette in the past month1. Smoking rates are two to four times higher among adolescents with psychiatric disorders such as attention deficit disorders, conduct disorder, depression, anxiety disorders, and alcohol and illicit drug dependencies2-4. Empirical investigations of adolescent tobacco treatment interventions number less than 50 with many of the studies criticized for methodological problems (i.e., follow up < 6 months, poor retention, lack of control or comparison groups)2,5, 6. There have been no unequivocal successes; however, promising interventions include stage-based, cognitive behavioral (CBT), and multicomponent treatments2, 7. Additionally, the nicotine patch is well tolerated and safe among adolescents8 and rarely abused9. Less than a third of adolescent tobacco users report intention to quit in the near future2, 10, 11; thus, it seems critical that cessation interventions for this complex group be designed to assist smokers at all stages of readiness through the quitting process. A stepped care approach has the potential of matching more intensive services to those ready for and in need of greater treatment. Interventions delivered in health care settings have the appeal of broad reach. The primary specific aims of this research are to evaluate, in a randomized clinical trial (N=160), the efficacy of a stepped care intervention for treating smoking among adolescents recruited from outpatient psychiatry settings. To our knowledge, this would be the first study to examine outpatient psychiatry settings for treating tobacco dependence in adolescents. The stepped care intervention combines expert-system contacts, individual CBT sessions, and 12-weeks of nicotine replacement therapy (NRT).
In the present study, we investigate healthy subjects and schizophrenic patients who frequently show very low attentional capacity with functional magnetic resonance imaging (fMRI) and electrophysiology (EEG) during attention-requiring tasks to assess the level of attentional network activity.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of Polyphenon E, a substance found in green tea, may keep cancer from forming in current or former smokers with bronchial dysplasia. PURPOSE: This randomized phase II trial is studying the side effects and how well green tea extract works in treating current or former smokers with bronchial dysplasia.
The purpose of this study is to test whether Varenicline can help ambivalent smokers (those who are interested in quitting at some point in the future but have no current plans to quit) to reduce their smoking and eventually quit.
The purpose of this study is to compare gain-framed counseling + gain-framed materials" to standard care Quitline counseling + standard print materials. The investigators hypothesize that gain-framed counseling + gain-framed materials group will produce higher abstinence rates than standard care counseling and standard care information. The data in this study will be used to determine effect size estimates for a large scale study.
The overarching goal of this line of research is to increase smoking abstinence rates using a combination of existing pharmacotherapies. The aim of the current study is to assess the safety and compliance as well as obtain preliminary estimates of efficacy and effect on craving and nicotine withdrawal of combination therapy with bupropion SR and varenicline. We will compare the efficacy estimates in this study with historical smoking abstinence rates with varenicline. To accomplish our aims, we will enroll 38 cigarette smokers in an open-label, phase II clinical trial.
Tobacco prevention and intervention strategies in the general population are ongoing and evolving. However, strategies to help cancer patients overcome tobacco dependence have been limited. Radiation oncology patients who continue to smoke despite their cancer diagnosis have a lower quality of life (QOL), increased frequency and severity of side effects during their cancer treatment, higher risks of developing a smoking-related primary cancer, and may have a poorer survival rate than their non-smoking counterparts. These are all compelling reasons to be more pro-active in helping cancer patients stop smoking. The overall objective of this project is to adapt a model of an effective tobacco use intervention that can be delivered by any trained radiation oncologist and their staff.
The primary purpose of this study is to determine whether, among smokers with elevated depressive symptoms, sequential antidepressant pharmacotherapy with fluoxetine (20 mg) begun 8 weeks prior to and extended throughout standard smoking cessation treatment with transdermal nicotine patch (ST-TNP) will result in superior short-and long-term smoking cessation outcomes compared to sequential pharmacotherapy with placebo medication combined with ST-TNP. The secondary aim of the study is to test the hypothesis that, among smokers with elevated depressive symptoms, sequential treatment with fluoxetine will result in lower levels of depressive symptoms and negative mood and higher levels of positive mood immediately prior to and throughout the course of smoking cessation treatment relative to the placebo condition.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. Green tea extract may keep cancer from forming. PURPOSE: This randomized phase II trial is studying green tea extract in preventing cancer in former and current heavy smokers with abnormal sputum.
Cocaine addiction continues to be an important public health problem in the US with a significant cost to the individual and society. Among substance abusers, cocaine use has been recognized as a significant problem especially in methadone-maintenance patients. In several studies, rates of cocaine use have been reported to range from 30 to over 60 percent of those in methadone maintenance programs (Condelli et al. 1991; Hunt et al. 1984; Kidorf and Stitzer 1993; Kosten et al. 1988). In these patients, cocaine use seems to be a predictor of poor clinical outcome (Hartel et al. 1995; Kosten et al. 1987a). The development of effective pharmacotherapies for cocaine use disorders, especially in the opioid-dependent population is of great importance. Unfortunately, such effective pharmacotherapies do not exist. 1. To determine the safety and tolerability of varenicline in cocaine-using methadone-stabilized subjects. 2. To determine if varenicline is efficacious in reducing cocaine-use in methadone-stabilized subjects.
