Filter by:Prior clinical trials examined several schedules of a nicotine vaccine (NicVAX) for anti-nicotine antibody responses, and their impact on helping smokers quit. The best schedule so far has been one with doses at weeks 0, 4, 8, 16 and 26. This new study tests whether changing the schedule to weeks 0, 4, 8, 12 and 16 is an improvement for stimulating antibodies to nicotine. Routine vaccine safety information is also collected. Amendment 1 adds a 6th dose at week 26, and extends follow-up through week 52.
It has been shown in the adult literature that smoking is related to depression and visa versa. Not much is known about how this relationship is started or if one perhaps leads to the other. We are performing 1 hour long interviews with adolescents ages 12-19 who meet criteria for major depression and who smoke. They are interviewed along with their parent. Questions center around their view of depression and their history of depression as well as questions around their smoking as well as the interrelationships between the two. Transcripts are made of the interview and are being analyzed for themes.
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.
The goal of this pilot study is to determine the feasibility and potential effect size of nicotine lozenges as an adjunct to maintain brief preoperative abstinence, defined as not smoking the day of surgery.
80 nicotine dependent adults ages 18-65 who desire to quit smoking will be screened and, if eligible, enrolled and randomized to one of two four-week treatments for smoking cessation. The treatments are standard behavioral therapy and Mindfulness Based Addiction Therapy (MBAT), which is standard therapy plus mindfulness. Standard therapy and MBAT incorporate elements of widely-used tools for smoking cessation including managing craving and strong emotions, problem solving, tips on healthy eating and keeping active, and exercises based on cognitive and behavioral therapy. MBAT uniquely incorporates mindfulness practice (a relaxation therapy) into standard therapy. Participants complete questionnaires and undergo an fMRI scan at baseline and at the end of therapy (after they complete the 4 weeks of standard therapy or MBAT). During each scan, participants will complete a validated smoking-related cue paradigm and a validated affect labeling paradigm.
Objectives: 1. Assess MAPS and MAPS+ effects on alcohol at-risk behaviors and smoking cessation. 2. Assess MAPS and MAPS+ effects on treatment mechanisms (increased self-efficacy, decreased temptations/craving, decreased stress and negative affect) and the role of those mechanisms in mediating MAPS and MAPS+ effects on alcohol at-risk behaviors and smoking cessation. 3. Evaluate the cost-effectiveness of MAPS and MAPS+ in the reduction of at-risk drinking and smoking cessation.
This study is a randomized controlled trial designed to evaluate the effectiveness of a nurse delivered stage-matched intervention to cardiac patients for cessation of tobacco use. Review of literature shows that there is a clear lack of empirical evidence on (1) using nurses to deliver stage-matched smoking cessation interventions, and (2) the effectiveness of such intervention for cardiac patients in Chinese populations. The ultimate goal of the intervention achieve a higher quit rate in the intervention group than in the controls. In addition, the change in the patient's smoking behaviour such as reduction of the number of cigarettes smoked, and progression to a higher stage of readiness to quit, will also be measured. This study is the first step to address the urgently needed data for (1) promoting the delivery of nurse-run stage-matched smoking cessation interventions to help patients stop smoking, (2) developing smoking cessation policy and programmes in the hospitals and for the health care system, and (3) contributing an evidence-based approach to orientate clinical services towards prevention, so as to reduce premature deaths and the enormous disease burden of our society.
Cigarette smoking continues to be a major public health problem. Tobacco dependence interventions, as recommended by the USPHS Clinical Practice Guideline are not effective for all smokers. A need exists for new medications to treat various aspects of tobacco dependence, such as the reinforcing effects of nicotine, relief of nicotine withdrawal symptoms and prevention of early relapse. The neurobiology of the effect of methylphenidate is similar to that of the reinforcing effects of nicotine. In a small previous study, methylphenidate was reported to improve nicotine withdrawal symptoms and short term quit rates. Methylphenidate is well tolerated, has low abuse potential, and is less expensive compared to other tobacco dependence interventions. ConcertaTM, a long acting preparation of methylphenidate, is administered once a day, has similar bioavailability as the generic drug administered 3 times a day and has an overall similar or improved efficacy compared to generic methylphenidate. We plan to obtain preliminary efficacy data in a randomized, placebo-controlled phase II study assessing the effect of methylphenidate in cigarette smokers for increasing 7-day point prevalence smoking abstinence at end of treatment and 7-day point prevalence and prolonged smoking abstinence at 6-months. Critical and systematic evaluations of newer, innovative, and well-tolerated treatments to help treat tobacco use and dependence will provide a wider choice of therapeutic agents to smokers wishing to become abstinent from tobacco use.
The purpose of this study is to determine the impact of carotid plaque screening on smoking cessation and control of other cardiovascular risk factors.
