Filter by:The purpose of the study is to test the efficacy and safety of bupropion SR for smokers hospitalized with acute cardiovascular disease.
The researchers will study 100 families over three years, each with a child (proband) between the ages of 12-17, with the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis of ADHD. The researchers hypothesize smoking will be familial and ADHD probands with a family history of tobacco use will be at increased risk for early initiation and persistence of smoking, compared to ADHD probands with no family history of tobacco use.
Smoking substantially inhibits the activities of both monamine oxidase (MAO) A and B enzymes. Aims of this study: to compare MAO activities and nicotine and cotinine in peripheral blood of smoking and nonsmoking pregnant women, in their placenta and in cord blood and relate them with the behavior of their newborns being observed during 48 hours after birth.
The goal of this study is to understand how information about smokers' health risks affects their attitudes, mood, and behavior.
In this randomised, cross-over, controlled study, a total of 84 subjects will be included: 12 healthy non-smoking volunteers; 12 current smokers; 30 patients with mild steroid-naïve asthma; and 30 patients with mild-moderate COPD. Each subject will have 1 screening visit (if necessary) and 2 study visits. At visits 2 and 3 the effects of adenosine 5'-triphosphate (ATP) or adenosine 5'-monophosphate (AMP) challenge, given in a random order, will be tested.
The primary hypothesis of this pilot study is that dependence can be prevented in adolescents who smoke, but who are not yet dependent. With this study, we seek to develop and test the feasibility and provide controlled comparisons of two brief smoking dependence-prevention interventions: motivational interviewing with feedback versus a video control. Forty adolescents between the ages of 12 and 18 will be enrolled. The evaluation and dependence-prevention phases will occur during a single 3- to 4-hour session, and the 30-45 minute follow-up sessions will take place approximately one month, three months, six months, and one year after the completion of the evaluation and dependence prevention phases.
The purpose of this study is to develop and evaluate the effectiveness of a parent-based intervention that can be implemented in conjunction with existing school-based programs designed to prevent or reduce sexual risk behavior or to prevent or reduce tobacco use in young adolescents. The parent programs are expected to have effects on adolescent behavior over and above the effects of the school-based programs.
This study will test a combination of the drugs naltrexone and bupropion with weight-concerned smokers to investigate whether or not this combination of drugs improves smoking cessation quit rates and minimizes post quit weight gain.
TeleQuit is a group randomized trial testing whether a telephone care coordination program increases the rate of smoking cessation treatment for VA patients at study sites. We are testing whether proactive care coordination (counselor initiates the call to the patient) is more effective than reactive coordination (coordinator waits for the patient to call); and whether multi-session counseling is more effective than brief primary care-based counseling plus self-help materials. We randomly assigned study sites to either quitline counseling or brief counseling only. All patients receive brief smoking cessation counseling from their primary care physician, smoking cessation medications (once they are in contact with the VA care coordinator), and a follow-up call at 6 months. Care coordination will be provided by VA clinical staff. Intensive counseling is provided by the California Smokers' Helpline.
Smoking can contribute to many health problems for mothers and their babies. In developing countries, there is little information about the number of pregnant women that smoke and the reasons why some pregnant women choose to smoke. The purpose of this multi-site tobacco use survey is to obtain information on knowledge, attitudes and behaviors among pregnant women in diverse populations regarding tobacco products.
