Filter by:This study will evaluate the impact of a proactive, EHR-supported enrollment strategy that links LDCT-eligible smokers with an evidence-based intervention comprised of a web-based program and integrated text messaging. The goal is to provide actionable findings about how to most effectively and cost efficiently promote abstinence in LDCT clinics.
Objective The purpose of this study is to examine the effects of auricular acupressure and group counseling with positive psychology and motivational interviewing on smoking cessation and tobacco withdrawal symptoms. Methods This study is a single blind randomized controlled trial. This study has been performed at a University in South Korea. 180 smokers and 60 non-smokers will be recruited. Smokers will be randomly assigned to three groups: group 1 (auricular acupressure + group counseling); group 2 (placebo acupressure + group counseling); and the control group (self-help smoking cessation). Group counseling is undertaken once per week for 6 weeks. Auricular acupressure using acupellets is performed for 6 weeks continuously.
This randomized controlled trial is going to evaluate whether an intervention consisting of a smartphone application to assist smokers living with HIV to quit in combination with CO self-monitoring compared to stop smoking counselling by physicians during usual care results in higher self-reported and biochemically verified smoking cessation rates at 6 months. .
Investigation on the effect of smoking on thrombus formation in humans. The expression of pro- and anti-thrombotic, anti-oxidative, and inflammatory markers will be assessed in 25-50 year old healthy smokers and non-smokers. The investigators are interested in possible differences between the two groups.
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.
Tobacco use is the number one killer of Americans today. Most current smokers have tried and failed to quit at least once. Smokers are addicted to the nicotine in tobacco products, and withdrawal from smoking can lead to physical symptoms such as irritability, anxiety, nervousness, depression and insomnia. This study will examine the effects of tobacco cessation counseling and chiropractic treatments on smokers who desire to quit.
To investigate the effectiveness of a smoking cessation intervention of two sessions (120 min at a time) in a group setting on the basis of Motivational Interviewing (MI) and important elements of Cognitive Behavioural Therapy (CBT). According to national and international guidelines patients are advised to quit and pharmacologically supported with one of the established first line smoking cessation treatments.
This is a 2-group RCT in 380 tobacco-using medical patients that will compare a single session, computer-directed 5 A's intervention for smoking (experimental condition) to screening and resource provision (control condition). Follow-up visits will occur at 1 and 3 months post study enrollment. Measures will focus on tobacco use and related psychosocial outcomes (e.g. mood, stress). We will compare resources used and economic costs needed to implement each intervention. The Investigators hypothesize that patients receiving the computer-directed intervention will have significantly higher tobacco abstinence rates at 3 months post study enrollment compared to the control group. If indeed the computerized intervention increases tobacco abstinence rates compared to the control group, this intervention could be used to increase access to treatment for the millions of US smokers, ultimately reducing tobacco mortality and morbidity rates in this country.
