Filter by:The purpose of this study is to examine the effectiveness of an internet-based contingency management program for smoking cessation in persons who are homeless. Thirty homeless smokers will be enrolled in the study. Participants will receive payment based on their own low carbon monoxide readings, which indicate being quit from smoking. Participants will be prescribed nicotine replacement (patches and either gum or lozenge)and bupropion. All participants will receive a four sessions of smoking cessation counseling, and will be trained to perform carbon monoxide monitoring with a device provided by the study. They will also be provided with a mobile phone equipped with a video camera, and will use this equipment at home to monitor their carbon monoxide . Participants will record videos of themselves taking a carbon monoxide reading and displaying the results, and will upload the videos to a secured website that is only accessible by the research team members and the participant. Payment will be based on providing carbon monoxide readings that indicate abstinence. The study is designed to address the following aims: Specific Aim 1: To evaluate whether it is feasible to use internet-based contingency management for helping smokers who are homeless stop smoking. Specific Aim 2: To evaluate how effective internet-based contingency managementis on decreasing smoking in smokers who are homeless.
The primary aim of this research study is to enhance smoking cessation outcome among smokers with anxiety disorders. The investigators are comparing two group treatment approaches: (1) An educational-supportive psychotherapy and standard smoking cessation treatment, and (2) An integrated smoking cessation and anxiety treatment program (START). Both treatments also utilize nicotine replacement therapy.
This study tests whether pre-cessation interventions known to be effective in the general population will increase acceptance of evidence-based treatment, engagement and compliance with that treatment and initial quitting success. One hundred and seventy two patients will be recruited from 13 Community Support Programs (CSPs). CSPs provide community based care to those diagnosed with persistent and serious mental illness. All participants will receive two group sessions (40 minutes each) modeled after "Kicking Butts", a group-based quitting preparation program used for the past four years in two Milwaukee CSP programs run by Wisconsin Community Services. Individuals will then be randomly assigned to the experimental and control conditions (n=86 each). Experimental subjects will receive four evidence-based preparatory interventions (motivational interviewing, smoking reduction, practice quit attempt, and pre-quit use of nicotine replacement medication) (25 - 30 minutes each). Attention control subjects will also receive four individual sessions of the same duration. However their individual sessions' content will be a discussion of the personal relevance of the group material and will not include any of the preparatory interventions. Data will be collected via brief surveys taken pre-intervention, at the end of the last individual session, and three months later and from a database provided by the Wisconsin Tobacco Quit Line (WTQL).
The goal of this exploratory study is to evaluate the effect of a candidate modified risk tobacco product (MRTP), THS 2.1, on selected biomarkers of exposure to harmful and potentially harmful smoke constituents (HPHCs), compared to conventional cigarettes (CC). The subjective effects (urge to smoke and withdrawal symptoms) which are related to the use of this product will be explored. Initial information on safety and on some biological effects when using THS 2.1 will be collected. Human Smoking Topography (HST) will be explored.
The main goal of this exploratory study is to evaluate the pharmacokinetic profile of nicotine for the candidate modified risk tobacco product THS 2.1 and for conventional cigarettes (CC).
The purpose of this study is to obtain biologic materials from the blood, airways and/or urine of normal individuals and individuals with lung disease. The normal are used to establish a set of normal ranges for various parameters. These provide control information when compared to individuals with various pulmonary diseases, and will help in understanding of the etiology and pathogenesis of various lung diseases. The underlying hypothesis is that the pathologic morphological changes in the airway epithelium must be preceded by changes in the gene expression pattern of the airway epithelium and potentially in macrophages.
This will be a retrospective study. Details on all women who delivered in McGill University between 2001-2007 will be retrieved anonymously from the MOND database (McGill University Obstetrics and Neonatal database). Women will be divided to 2 groups according to their smoking status in pregnancy. Obstetric complications will be recorded in both groups.
Smoking remains a major risk factor for chronic diseases and is a real problem for health systems. The use of emerging technologies, such as mobile phone , may have a important role in smoking cessation programs through sending reinforcement messages when patients quits smoking. Main objective: To evaluate the effectiveness of a combined 6 months smoking cessation program including health advice provided by a doctor and sending support messages to mobile phone of patients. Methods: Study design: Randomized single blind clinical trial. Study population: Patients over 18 who are willing to start a smoking cessation program, who have mobile phone, who are able to receive and send messages, and who have a score greater than 5 or equal to 5 on the Richmond scale. Sample size: 160 patients per arm to detect a difference in the percentage of smoking cessation than 10% (14.9% vs. 4.9%) between the two groups. Intervention: Experimental group: Health advice and support messages to mobile phone patients. Control group: Health advice. Assessment of the primary endpoint: At 6 months (positive/negative coximetry test). Statistical analysis: The analysis of the primary endpoint (positive / negative coximetry test) will be performed using logistic regression.
Veterans with a mental health diagnosis have higher a prevalence of smoking and higher rates of smoking-related morbidities compared to the general Veteran population. Smoking cessation treatment delivery in the VA typically depends on a visit from a health care provider. In this study, investigators will use information within the electronic medical record to identify all smokers with a mental health diagnosis at a VA health care facility and proactively reach out to enroll them in an intensive tobacco cessation treatment program. This approach could be generalized to other behaviors and provides a novel method to improve the health of an entire population of patients.
The purpose of this study is to examine whether doxazosin will attenuate the ability of stress to precipitate smoking lapse behavior in treatment seeking daily smokers. Participants will participate in a smoking cessation attempt after the laboratory sessions.
