Filter by:Background: Infants are at risk for tobacco-attributable diseases by being exposed to environmental tobacco smoke (ETS). International literature has shown that a home smoking ban can reduce ETS. The purpose of this study is to examine whether a brief feedback about urinary cotinine in infants and a counselling session about the consequences of ETS leads to a reduction of ETS. All families with children up to an age of three years in the study region will be contacted by mail and asked for participation in this study. They will be randomised into an intervention and one control group. The intervention group will receive a ETS counselling session and detailed analysis of urinary cotinine (a biomarker of ETS) at their home. They will further receive written feedback approx. 2 weeks later. The control group will be visited and will answer a questionnaire and will receive brochures about ETS. They will receive a standard analysis feedback of urinary cotinine. There will be oine further assessment/ visit 12 months later. The outcome of this study is an anlysis of urinary cotinine and smoking behaviour and changes in cotinine and smoking behaviour.
The overall goal of this study is to identify and understand the environmental characteristics associated with tobacco use and tobacco initiation among Asian American youth from primarily two communities: Chinese and Vietnamese. The specific aims of this study are twofold: - To estimate the prevalence of smoking among Chinese and Vietnamese youth in the Houston area compared with non-Asian American communities. - To study the relationship between environmental characteristics (both pro- and anti-tobacco) and tobacco initiation and use among Chinese and Vietnamese youth. - To explore if degree of acculturation is related to tobacco initiation and use among Chinese and Vietnamese youth.
The purpose of this study is to evaluate the efficacy and safety of varenicline in Japanese smokers. Efficacy is evaluated by continuous quit rate and withdrawal symptoms of smokers. Safety is evaluated by adverse events, laboratory tests, and other safety tests.
Over 1 billion people worldwide smoke, resulting in an estimated 4 million deaths annually from smoking-related disease.1 Persistent and long-term smoking leads to an increased risk of cardiovascular damage, respiratory disease, and a higher incidence of a variety of cancers; but for smokers who can quit there is an immediate and significant beneficial impact on their health and life expectancy. Cigarette smoking remains the leading preventable cause of death in the United States (US), accounting for approximately 1 of every 5 deaths (438,000 people) each year. This Phase 2 study will investigate the efficacy and tolerability of 2 doses of TA-NIC compared to placebo as an aid to smoking cessation in smokers who are motivated to quit.
A total of 20 subjects will participate in this four week, between groups, double-blind, placebo controlled study. Subjects will participate in two experimental sessions separated by approximately one week. Subjects will be randomized to receive either 50 mg cycloserine or placebo combined with cue exposure. Several physiological and subjective outcome measures (e.g., heart rate, blood pressure, galvanic skin response) will be obtained during the sessions. Experimental sessions will last approximately 4.5 hours with follow-up sessions lasting approximately thirty minutes. Our aims are: 1. To examine the effect of cycloserine vs. placebo on extinction of smoking cue reactivity in overnight abstinent smokers. Reactivity to smoking cues will be captured with self-report smoking urges and physiological measures (heart rate, blood pressure, and skin conductance). We hypothesize that cycloserine, relative to placebo, will facilitate extinction of smoking cue reactivity. 2. To examine the effect of cycloserine vs. placebo when combined with two 4.5 hour laboratory cue exposure training sessions, on smoking behavior in smokers. Smoking behavior will be measured with self-report smoking and saliva cotinine levels. 3. To examine the effect of cycloserine vs. placebo on memory performance in nicotine dependent smokers. Memory performance will be measured with verbal learning, recognition and recall tasks. 4) To examine the safety and tolerability of cycloserine treatment in smokers. We hypothesize that cycloserine will be well tolerated by smokers.
Women who smoke during their pregnancy place their unborn child at an increased risk of health problems, including decreased lung function and possible lung diseases later in life. Preliminary animal research suggests that if vitamin C is taken during pregnancy, nicotine's harmful effects on the unborn baby's developing lungs may be blocked. This study will determine the effect that vitamin C has on the lung development and function of babies born to women who smoke during pregnancy.
Rates of cigarette smoking in the military are high. Tobacco telephone quit lines are telephone-based services that provide information and guidance to people who want to quit smoking. This study will evaluate the effectiveness of a tobacco quit line program, in addition to nicotine replacement patches, at helping people in the military quit smoking cigarettes.
Reducing tobacco use by adolescents is a national health priority. In recent polls, most adolescent smokers reported having tried unsuccessfully to quit. Smoking cessation treatment during adolescence has the potential to interrupt the progression to nicotine dependence, which is attended by a wide range of negative health consequences. Given the need for effective smoking cessation programs aimed at youth, scientifically rigorous research is warranted to reduce adolescent smoking. This project will address gaps in the scientific treatment literature. The goal of this project is to develop a tailored, practical, and efficacious smoking cessation intervention. Combined with other efforts in the field, this work can provide an initial guide to an evidence-based treatment for smoking cessation in youth. In keeping with developments in other fields of medicine, we believe that further advances in smoking cessation will move towards a goal of personalized treatment. Such an individualized approach for adolescent smoking cessation will be informed by further investigation of the relationships between outcomes in this trial. To serve these goals, we propose the following program: Youths who smoke regularly will receive a 6 week intervention using "cognitive-behavioral motivational enhancement" (CBME) supplemented by nicotine replacement therapy (NRT), if youth and parents desire this option. Furthermore, youth has to smoke more than 5 cigarettes a day in order to qualify for nicotine replacement therapy. This approach is consistent with treatment guidelines for smoking cessation (Fiore 2000). Compared with participants who fail to achieve smoking cessation, those who successfully achieve smoking abstinence during intervention, will have lower baseline rates of comorbid ADHD, lower depressive symptom scores, enhanced readiness to quit, more negative attitudes towards smoking, fewer friends who smoke, and fewer family members who smoke. The investigators predict that the intervention will help youth to quit smoking and will examine predictions of successful quitting.
Varenicline (Chantix) is a smoking cessation treatment that was approved in 2006 by the FDA for treatment of nicotine dependence and may be particularly beneficial in smokers with schizophrenia or bipolar disorder. Early experience with varenicline indicates that it will be effective for smoking cessation in schizophrenia and in addition, has the potential to be therapeutic for cognitive dysfunction in this population. In addition, more data is needed to evaluate the safety, tolerability and effectiveness of Varenicline in people with bipolar disorder. To assess this possibility, we will evaluate the safety and efficacy of 12 months of varenicline in schizophrenia or bipolar disorder patients who are able to quit smoking in the short term with this treatment. To do so, we will enroll 324 smokers with schizophrenia or bipolar disorder from 6 mental health clinics in Massachusetts, New Hampshire, Michigan and Minnesota into an open, 12-week smoking cessation program that includes varenicline added to weekly group cognitive behavioral therapy (CBT). Those who achieve at least 2 weeks of continuous abstinence during the last 2 weeks of the open intervention will be randomized to the relapse prevention phase: a 40-week, double blind, placebo-controlled trial of varenicline at the dose used to quit smoking added to a tapering CBT schedule. Participants will then discontinue study medications and behavioral treatment and enter a 3-month follow up phase.
