Filter by:The primary aim of this research study is to enhance smoking cessation outcome among smokers with elevated anxiety and depression. We are comparing two group treatment approaches: (1) An educational-supportive psychotherapy and standard smoking cessation treatment, and (2) An integrated smoking cessation, and anxiety and depression management treatment program (SDAT). Both treatments also utilize nicotine replacement therapy.
Primary Aim: To test the efficacy of a SMS text-based scheduled gradual reduction (SGR) and counseling intervention to promote smoking cessation in the late third trimester. Hypothesis: The rate of smoking cessation in the late third trimester among women in the SGR Support Messages arm will be higher than among women in the Support Messages arm. Secondary Aim 1: To assess the effect of the SGR intervention on biochemically validated prolonged abstinence and smoking reduction during pregnancy. Secondary Aim 2: To assess the effect of the SGR intervention on smoking abstinence at three months postpartum. Secondary Aim 3: To assess the effect of the SGR intervention on the rate of preterm birth.
The primary goal of the study is to evaluate the use of a new smart phone application in preventing relapse to smoking among people with PTSD. The technology intervention will combine a mobile system to reward non-smoking, smoking cessation counseling, smoking cessation medications, and use of the smart phone app. The primary aim is to evaluate how effective this intervention is in preventing smoking relapse compared to another intervention that does not include the app.
Evaluate if the ad libitum use of the THS 2.2 Menthol (mTHS), a candidate Modified Risk Tobacco Product, for 5 days in confinement, and after 86 days in an ambulatory setting, by apparently adult healthy smokers results in a reduction in the levels of biomarkers of exposure (BoExp) to selected harmful and potentially harmful constituents (HPHCs).
In this randomized controlled study it is investigated if a proactive action by the general practitioner offering individuals without formal education a preventive health check will lead to a larger number of diagnoses in form of chronic obstructive pulmonary disease, cardiovascular diseases, and diabetes among participants in the intervention group compared to the control group. Furthermore it will be investigated if the proactive action by the general practitioner will be associated with a higher smoking cessation rate at 12 month follow-up.
The primary aim of this study is to determine menthol smokers' perception, product preference, and pattern of use across six products including, 1) mint-flavored 2mg nicotine gum ; 2) mint-flavored 4mg nicotine gum; 3) non-flavored 2mg nicotine gum; 4) non-flavored 4mg nicotine gum; 5) mint-flavored electronic cigarette; and 6) non-flavored electronic cigarette. Fifty smokers (all African American menthol smokers) will be recruited for this study. Participants will undergo a baseline assessment followed by a 2-week product sampling phase.
In cigarette smokers that are HIV+, one of the most common HIV-associated non-AIDS conditions is the accelerated development of chronic obstructive pulmonary disease (COPD), a disorder associated with significant morbidity and mortality. Based on the knowledge that COPD in smokers starts in the small airway epithelium, this study is focused on examining the hypothesis that the accelerated development of COPD associated with HIV infection results, in part, from an interaction of HIV directly on the small airway epithelium or through infection of cellular components of the immune system, with mediators released by these immune cells evoking premature biologic aging of the small airway epithelium. By identifying the early events in the pathogenesis of the HIV-associated accelerated COPD in smokers, we aim to identify biologic targets to which pharmacologic therapies could be addressed.
Early changes associated with the development of smoking-induced diseases, e.g., COPD and lung cancer (the two commonest causes of death in U.S.) are often characterized by abnormal airway epithelial differentiation. Airway basal cells (BC) are stem/progenitor cells necessary for generation of differentiated airway epithelium. Based on our preliminary observations that epidermal growth factor receptor, known to regulate airway epithelial differentiation, is enriched in BC and its ligand EGF is induced by smoking, we hypothesized that smoking-induced EGF alters the ability of BC to form normally differentiated airway epithelium. To test this, airway BC will be purified using a cell-culture method established in our laboratory and responses to EGF will be analyzed using genome-wide microarrays and an in vitro air-liquid interface model of airway epithelial differentiation.
Cigarette smoking is the major cause of chronic obstructive pulmonary disease (COPD), the 4th cause of mortality in the US. Central to COPD pathogenesis is "ciliopathy", dysfunction of the airway ciliated cells that mediate transport of mucus to remove inhaled pathogens. The focus of this study is to carry out metabolic profiling of banked biologic samples and assess the hypothesis that COPD is associated with a unique metabolome in serum and lung epithelial lining fluid, and that subsets of the COPD metabolome are linked to the ciliopathy of COPD.
Cigarette smoking evokes major changes in the biology of the airway epithelium, the cell population that takes the brunt of the stress of cigarette smoke and the cell population central to the pathogenesis of chronic obstructive pulmonary disease (COPD) and lung cancer. The focus of this study is to identify the differences that two popular alternative nicotine delivery strategies, shisha and electronic cigarettes, have on the airway epithelium compared to cigarette smoking. We hypothesize that both alternative nicotine delivery strategies disorder airway epithelial biology, but in different ways than does cigarette smoking.
