Filter by:20% of Ontarians smoke. There was a decline in smoking prevalence from 1995 but it has remained unchanged since 2002. This rate of smoking cessation has not kept up with the rest of Canada. A new strategy is necessary to increase the number of smokers making quit attempts and to increase the odds of quitting long term.The goal of this study is to evaluate the methods and effectiveness of providing nicotine replacement (NRT) to Ontario smokers. The study will develop an evidence-based protocol for providing NRT, provide faculty development on combining pharmacotherapy with behavioural interventions and will provide an evaluation framework to inform future coverage models.
The primary objective is to demonstrate the efficacy of dianicline as an aid to smoking cessation in cigarette smokers. The main secondary objectives are: to assess the craving for cigarettes, nicotine withdrawal symptoms and the safety of dianicline.
Approximately 2 million Ontarians are current smokers. While smoking rates have declined over the past 25 years, these rates have remained constant since 2002. The rate of smoking cessation in Ontario has not kept up with the rest of Canada. A new strategy is necessary to increase the number of smokers making quit attempts and to increase the odds of quitting over the long term. The overall goal of the Stop Smoking Therapy for Ontario Patients (STOP) Study is to evaluate the methods and effectiveness of providing nicotine replacement therapy (NRT) to Ontario smokers. The study will develop an evidence-based protocol for providing NRT, provide faculty development on combining pharmacotherapy with behavioural interventions and will provide an evaluation framework to inform future coverage models. The goal for this phase of the STOP study is to provide faculty development on combining pharmacotherapy with behavioural interventions. This will be achieved by partnering with Public Health Units across Ontario who have established smoking cessation clinics but do not have the finances in place to offer NRT to their clients at a subsidized rate or free of charge. Cost has been shown to be a significant barrier to the access and use of NRT in individuals trying to quit smoking. However, combining pharmacotherapy with behavioural interventions may be more effective than either alone. Therefore, we hypothesize that providing NRT free of charge to clients enrolled in a smoking cessation clinic will be more effective for smoking cessation than behavioural interventions alone.
This study will compare the effectiveness of counseling plus use of a nicotine patch with counseling alone for helping pregnant women quit smoking. Smoking during pregnancy is the most preventable cause of fetal and newborn health problems such as low birth weight, fetal growth retardation, sudden infant death syndrome, spontaneous abortion, decreased lung function and premature delivery. African-American and Hispanic women 18 years of age or older, smoke cigarettes, and live in the District of Columbia metropolitan area may be eligible for this study. Candidates are recruited from the George Washington University and Providence Hospital prenatal health clinics. They are screened with a review of their medical records and a survey that includes questions about their age, residency, race and ethnicity, educational level and employment status, number of weeks pregnant, and exposure to cigarette smoke and other types of tobacco. Participants answer questions about their smoking behavior, then receive a 10-minute counseling session and watch a videotape about quitting smoking. Women who are not able to quit smoking in 1 week are then randomly assigned to one of two treatment groups. One group continues to receive counseling sessions during the remainder of their pregnancy; the second group receives nicotine patches as well as the counseling sessions. In addition, all participants watch a video about smoking and receive a guide to help them quit. Women who receive the patches must stop smoking completely. If they cannot stop immediately, their participation in the study ends. The behavioral counseling sessions for all the women are a series of conversations between the women and a trained counselor to help the woman through the process of quitting. Participants are followed during the study with six clinic visits and three telephone calls. During the first visit, the women answer a series of questions about their smoking habits and health concerns. A portion of the urine sample they provide during their routine prenatal visit is used by this study to assess their cotinine (a breakdown product of nicotine) levels. Saliva and breath samples to test for cotinine and carbon monoxide levels are collected at each visit. Saliva is collected by brushing the inside of the cheek with a cotton swab, and breath samples are collected by having the woman blow into a tube connected to a machine. Participants are evaluated four times during the study with questions about their smoking behavior. With the women's permission, their medical records, health, and treatments during pregnancy are reviewed. At the end of the pregnancy, the infant's weight and health are also reviewed.
The purpose of this research study is to: 1. compare the effectiveness of a nicotine patch and nicotine nasal spray for smoking cessation; and 2. identify predictors of response to these alternate forms of nicotine replacement therapy (NRT).
It has been shown in rodent models that chronic substance abuse is associated with a rigidification of cell membrane fluidity due to a change in the membrane cholesterol/phospholipids ratio. Upon substance withdrawal the membrane undergoes reequilibration of this ratio, a process resulting both in an acute and a prolonged severe withdrawal syndrome. MBM has developed a patented,phosphatidic acid-enriched phospholipid platform ("LIBERTAL"), which is supposed to facilitate the membrane fluidity recovery. The company has focused on nicotine withdrawal in smoking cessation,as primary target.
The investigators propose to conduct a randomized controlled trial at the patient level of the Telephone Linked Care - Behavioral Change (TLC-BC) system, which is designed to promote smoking cessation, reduce risky drinking, and improve physical activity and diet. They expect to: 1. successfully integrate an automated telephone behavior change intervention into primary care practices; 2. demonstrate improvement in health behaviors for individuals randomized (assigned by systematic chance) to use the TLC-BC system compared to individuals who receive written health education informational packets; and 3. evaluate the direct costs associated with the use and operation of the TLC-BC system. Project aims and hypotheses follow: Aim 1: Integrate a proven, totally automated computer telephone intervention, Telephone Linked Care - Behavior Change (TLC-BC), into primary care practices. This will be assessed by the patient and clinician/staff surveys at the end of data collection. Aim 2: Demonstrate an improvement in health behaviors for individuals randomized to use the TLC-BC system compared to individuals who receive written informational packets. Aim 3: Evaluate the direct costs associated with the use and operation of the TLC-BC system within the primary care setting. Hypothesis 1: The Telephone Linked Care - Behavioral Change system will be successfully implemented by patients and practices. Hypothesis 2: At 6 months a clinically significant improvement in behavioral change rates will be demonstrated for diet, physical activity, and smoking in the intervention group compared to patients in the control group. Hypothesis 3: At baseline, 3, 6, and 9 months risky drinking will be identified, but there will be no difference in improvement between the study groups.
The primary purpose of this study is to examine the effect of a brief preoperative smoking intervention on postoperative complications in women undergoing breast cancer surgery. Secondary purposes are to examine long-term smoking cessation rates and experienced stress and nicotine withdrawal symptoms during the smoking cessation period.
The goal of this behavioral research study is to create and study a Mindfulness-Based Addiction Treatment (MBAT) for nicotine dependence. Mindfulness is a method to help focus attention on being in the "here and now." It can be learned through training in how to control one's attention. It is usually taught through meditation. The overarching goals of the study are to evaluate the efficacy of MBAT for nicotine dependence and the mechanisms and effects posited to mediate MBAT's impact on abstinence.
The purpose of the study is to determine whether a program of screening and intervention for four health risk behaviors (smoking, problem drinking, sedentary lifestyle, unhealthy diet) carried out by medical assistants in primary care practices can help patients improve their behaviors. The hypothesis is that patients who receive the intervention will demonstrate higher rates of health behavior change than patients who receive usual care.
