Filter by:Long-term NRT has not been studied in patients with COPD, and smokers in the United States with COPD are still asked to choose between immediate quitting or continued smoking. The purpose of this study is to see if guided maintenance therapy (GMT), using long-term NRT, might prove to be a reasonable alternative to the standard approach of asking patients to quit immediately. The investigators believe that GMT with long-term NRT will reduce overall exposure to cigarette smoke, reduce harm related to smoking, and ultimately lead to greater quit rates. In this study, 398 smokers with COPD will be randomly assigned to either receive: 1) traditional smoking cessation (SC) or 2) long-term, guided maintenance therapy with NRT (GMT). The SC intervention will be based on a standard approach to smoking cessation, including smoking cessation counseling supplemented with combination NRT (a nicotine patch plus the patient's choice of gum or lozenge) if they are willing to make a quit attempt. The GMT intervention will consist of counseling, focused on medication adherence and smoking reduction, plus 52 weeks of combination NRT. After 3, 6 and 12 months of treatment, we will compare the two treatments based on their effects on smoking cessation, number of cigarettes smoked, exposure to carbon monoxide and smoking-related carcinogens, COPD symptoms, breathing function, and smoking-related hospitalizations or death. The investigators will also analyze the data in such a way that will be able to identify which patients are most likely to benefit from treatment. This analysis will allow patients to estimate their chances of success based on their own personal characteristics and which treatment they choose. The investigators study addresses research priorities identified in recent smoking cessation guidelines and builds upon the input of our Patient Advisory Panel and our Stakeholder Advisory Committee. This study reflects the interests expressed by smokers in prior surveys and addresses the limited reach and effectiveness of traditional approaches to smoking cessation. If our GMT approach is effective, our study could change the recommendations provided in clinical practice guidelines and change the way that insurance companies pay for smoking cessation treatment. GMT could provide an alternative for millions of smokers with COPD who are not currently benefiting from traditional approaches to smoking cessation
This purpose of the study was to investigate the efficacy of telephone counseling to help pregnant women quit smoking. The investigators tested two hypotheses: 1) telephone counseling increases the overall cessation rate during pregnancy, and 2) the counseling effects can be maintained postpartum.
The Meriter Smoking Cessation Study tests participants in the Meriter Smoking Cessation Program. Meriter Hospital and clinic patients will be recruited into the Meriter Smoking Cessation Program. The Meriter Smoking Cessation Program has two interventions, the Mindfulness Training for Smokers (MTS) intervention and the Quit Line (QL) Intervention. Study activities include one 10-minute study visit and two 5-minute survey phone calls.
Smoking cessation improves health conditions with reduction of the risk factors for cardiovascular and respiratory disease, as functional capacity and quality of life. Smoking cessation has positive effects on the miRNAs regulation, however, genomics has been little explored. Smoking and aging induces changes miRNAs. Among the changes in airway epithelial cells, miR-125 called attention because it is enrolled in the suppression of ERBB7 (tirosin kinase receptors), a codified sequence of the growth factor receptor (EGFR) frequently expressed in cancer. The reduction of miR-125 expression may reduce cancer suppression resulting in cancer development. Other miRNA changes can be observed, such as miR-218 that were found in smokers airway epithelial cells as in MiR-15b that were found in lung tissue of COPD smokers. These miRNAs participated in the signalling pathway of TGF-β enrolled in leukocyte migration and cell proliferation. The investigators hypothesize that smoking cessation has a role in the regulation or reduction in the genetic changes smoking-induced. The investigators will assess the subject genomic profile at the baseline, 6 months and 12 months after smoking cessation.
The purpose of this study is to test the effectiveness of a smartphone application for smoking cessation in smokers ages 18 to 65 years.
Smokers will use a smartphone app on a smartphone provided for the study that will passively sense and record information about their activities. Information collected from the smartphone app will be used to develop future smartphone apps that will predict when an individual is at risk of smoking.
The study is a 2 year community based cluster randomized controlled trial to assess the role that a community health worker led intervention, in concert with physician education, can play in controlling the principal cardiovascular risk factors, i.e. hypertension, tobacco use, diabetes mellitus, physical inactivity and an unhealthy diet. Participants will include around 3600 adults, 35-70 years of age, from the urban community in the town of Dalkhola, Uttar Dinajpur district, West Bengal, India. The hypothesis of the study is that a community health worker based approach can result in increased control of Hypertension, Diabetes and Smoking.
The purpose of this study is to determine biomarkers of exposure to Harmful and Potentially Harmful Constituents (HPHCs) in Cigarette Smoke and cardiovascular-related biomarkers in smokers and non smokers.
The purpose of this study is to evaluate the use of "sampling" of smoking cessation medications (nicotine patches and lozenges) among smokers seen in primary care settings. Half of study participants will be provided with samples of medication, to use however they wish; the other half will not be provided with these samples. All smokers will be advised to quit through routine contact with their physician. After the primary care contact, all participants will be contacted by phone for three brief follow-up interviews, which will involve answering questionnaires about their smoking habits.
This is a pilot study to test the feasibility of conducting a text based smoking cessation trial with Emergency Department patients who are smokers.
