Filter by:The purpose of this study is to determine if checking smoking status as a routine vital sign increases the delivery rate of cessation counseling to adult smokers in primary care practices.
Nicotine dependence has not been sufficiently addressed in current state-of-the-science cessation interventions for pregnant smokers. The weight of the evidence from the general population of smokers suggests that nicotine replacement therapies may be beneficial cessation aids for pregnant smokers who are unable to stop smoking. The tremendous potential of these therapies for promoting smoking cessation among pregnant women creates a pressing need for decision tools and protocols to encourage treatment adherence that is essential for rigorous evaluation of the effectiveness of OTC NRT when provided as part of prenatal care. The results of this research could be directly translated to the improvement of obstetrical care providers' clinical practices. Medically supervised use of OTC NRT by pregnant smokers is an alternative to continued smoking that has the potential to substantially increase rates of smoking cessation during pregnancy.
The purpose of this study is to obtain biologic materials from the blood and lungs of normal individuals to establish a set of normal range for various parameters. These will provide important information when applied to individuals with various pulmonary diseases, and will help in understanding of the etiology and pathogenesis of various lung diseases.
This study will look at the genetic profile of cells taken from the oral cavity of healthy college students who smoke and who do not smoke cigarettes. This will be done using a small brush similar to that used in Pap tests for cervical cancer detection. Our aim is to determine if smoking causes early genetic changes in the DNA of these cells such as have been seen in the cells of cancerous tumors of the head and neck area and nearby healthy tissues. This will be correlated with data from subject questionnaires to assess tobacco use, and other behavior and demographic information.
Among all racial/ethnic groups, African Americans have the greatest risk of becoming ill or dying from tobacco-related diseases. Because of this disproportionate disease burden, it is particularly urgent that researchers focusing on tobacco control partner with African American communities. Intervention strategies which hold the tobacco industry accountable for its behavior are effective in changing views of tobacco use. In earlier work, the investigators found that information from internal tobacco industry documents, when shown to African American smokers, stimulated reflection about quitting and interest in disseminating information about industry targeting behaviors to others. However, to date there have been no attempts to utilize the information in industry documents as part of a smoking cessation intervention. In this project, the investigators will test whether a community co-developed, tailored quit-smoking program featuring exposures to African American-specific tobacco industry documents and media exercises in addition to proven individual quitting strategies can increase the number of people who quit smoking at six months and one year, as compared with usual care. The specific aims of the project are to: 1. test, using statistics, how well an innovative community-based, culturally tailored quit-smoking program for African Americans works at 6 and 12 months; 2. test selected variables for how well they predict who will return to smoking; 3. use interviews to identify additional individual and/or community factors associated with successful quitting or relapse; and 4. collect information to evaluate the overall effectiveness of the CARA project collaborative efforts in developing and sustaining the project over time, enhancing community awareness of tobacco issues, and creation or enhancement of community tobacco control resources.
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.
