Filter by:This study will analyze a series of biological and behavioral markers in different populations of smokers. The study groups will differ in their cigarette consumption and level of nicotine dependence. This analysis will help to identify factors that might be important for smoking behavior and nicotine addiction. The results from this study will contribute to improve campaigns for smoking prevention and treatments for smoking cessation.
The goal of this patient-randomized effectiveness trial is to demonstrate that an inpatient technology-supported assisted referral (I-TSAR) and follow-up approach is an effective and cost-effective method to help hospitalized patients successfully quit smoking. The proposed study represents a unique opportunity to assess the effectiveness and cost-effectiveness of linking inpatient and outpatient delivery of smoking cessation services in two large and very different health care delivery systems. We will enroll 900 participants (600 intervention, 300 controls) over 15-months and collect follow-up survey and health care utilization data over 12 months to estimate: 1) smoking abstinence at 6 and 12 months for I-TSAR intervention recipients compared to usual care; 2) the dose effect on smoking abstinence at 6 and 12 months for I-TSAR recipients compared to usual care; 3) total and mean costs per participant for I-TSAR and usual care recipients, and, if effective, estimate the incremental cost-effectiveness of the intervention vs. controls at 12 months from health plan/insurer and societal perspectives; and 4) differences in health care utilization at 12 months for I-TSAR versus controls.
A decision aid tool will be developed using participatory research approach. The decision aid will be targeted to cigarette smokers scheduled for elective surgery.
The purpose of this study is to determine, among a sample of general adult smokers, the effectiveness of three different counseling interventions for motivating quit attempts among smokers not yet ready to quit.
Would you like to quit smoking? Seattle's Fred Hutchinson Cancer Research Center is launching a new study that may be able to help. Participants who enroll in this study will be randomly assigned by computer (like flipping a coin) to one of two online programs. The goal of this study is to learn which of these programs is the most effective at helping people stop smoking. Findings from this study will be used to help build more effective online smoking cessation programs in the future. Participants in both of the smoking cessation programs used in this study will receive: - Interactive tools for dealing more effectively with urges to smoke - Step-by-step guides for quitting smoking - Personalized plans for quitting and remaining smoke-free - Electronic links for reaching one-on-one expert help for quitting Participants will be asked to complete online questionnaires, including a brief three-month follow-up survey. There is no cost for participating in this study. To enroll in this study or for more information, please visit www.webquit.com. This study is being conducted by Seattle's Fred Hutchinson Cancer Research Center (www.fhcrc.org), a world leader in advancing the prevention, diagnosis and treatment of cancer. The principal investigator for the WebQuit smoking cessation study is Dr. Jonathan Bricker, a faculty member at both the Hutchinson Center and at the University of Washington in Seattle.
Endostatin, a 20-kDa cleavage product of collagen XVIII, is a component of the extracellular matrix expressed in the basement membrane. As a potent inhibitor of angiogenesis, endostatin induces endothelial cell apoptosis and diminishes cell migration, adhesion and proliferation. Endostatin may stop the progression of atherosclerosis. Atherosclerotic heart disease involves unwanted tissue growth. By cutting off the blood supply from a plaque the likelihood of plaque rupture may eventually be reduced. Recent data indicates that the loss of collagen XVIII/endostatin is related to the enhancement of neo-vascularization and vascular permeability in atherosclerosis. Plaque neo-vascularization strongly correlates with the regional content of inflammatory cells. Furthermore, increased vascular permeability enhances lipid accumulation in the vessel walls, hence increasing foam cells. Therapeutic angiogenesis is a most promising strategy for the treatment of myocardial infarction. However, it remains unknown if and how endogenous angiogenesis inhibitors, such as endostatin, regulate angiogenesis in myocardial infarction. Rat models showed that after myocardial infarction endostatin neutralization displayed adverse left ventricular remodeling and severe heart failure compared with controls. Although angiogenesis was increased, tissue remodeling and interstitial fibrosis were further exaggerated in post-myocardial infarction hearts by endostatin neutralization. However, several studies suggest that endostatin may locally modulate coronary collateral formation by inhibiting collateral vessel formation in patients with ischemic heart disease. During treadmill exercise tests in healthy volunteers a significant increase in circulating endostatin levels can be observed. Exercise induces angiogenesis in cardiac and skeletal muscles by decreasing endostatin in the muscle tissues to increase blood flow to these metabolically active tissues. Thereby endostatin is released into the general circulation. In summary, endostatin might be a new weapon to fight against atherosclerotic progression by inhibiting neo-vascularization of atherosclerotic plaques.
The purpose of the "Weigh2Quit" study was to test in a randomized trial, a "weight concerns" intervention designed to reduce weight concerns that might impact cessation, increase physical activity and adherence to tobacco treatment, increase confidence in quitting, improve tobacco quit rates and decrease weight gain post-quit.
The objectives of this project are to develop and evaluate a multi-level approach to tobacco treatment for low-SES and minority patients. The components of this intervention would include Integrated Voice Response(IVR)-facilitated systematic outreach, linkage to a tobacco treatment specialist, free Nicotine Replacement Therapy (NRT) directed at the patient, and integration of this program with both an individual's primary care physician through an electronic health record (EHR), as well as referral to community resources to address the socio-contextual barriers to tobacco cessation. To achieve these objectives, this intervention will test an innovative model of systematic outreach to low-SES and minority smokers using systematic phone outreach (including cell phones which are particularly prevalent among minority and low-SES groups), coordinated with the PCP, using both a cost-effective technology and a dedicated tobacco treatment specialist to increase smoking cessation in these populations. The proposed intervention will have multiple levels of influence (patient, PCP) and provide linkages to community resources. If successful, this model could be generalized to other health systems with an EHR, which are increasingly being promoted to improve the safety and quality of health care. Hypothesis 1 (Reach and Effectiveness): An EHR-linked, IVR-mediated personalized treatment program for low-SES and minority smokers can reach these patients to increase quit rates and use of tobacco treatment effectively. Hypothesis 2 (Adoption and Implementation): An EHR-linked, IVR-mediated personalized treatment program for low-SES and minority smokers can be adopted across a variety of practice settings and be consistently implemented across diverse patient populations.
The investigators study will use a randomized controlled design. Eligible and consenting participants will be randomly assigned to one of two conditions: (1) DARSSA Intervention condition, or (2) Minimal Intervention Control condition. All enrolled participants will undergo the DARSSA baseline assessment and will be interviewed immediately following their ED discharge to assess relevant outcomes, such as whether they were asked about substance use and given a referral during their visit. This is referred to as the post-visit interview. All risky substance users enrolled during all phases will be interviewed again at 1- and 3-months post-visit to assess substance use, treatment engagement, and other outcomes. The primary difference between the two conditions is that, for the DARSSA Intervention condition, the subjects will have their reports printed and will be given the option of receiving the dynamic referral, while for the Minimal Intervention Control condition the subjects will undergo the assessment and will receive the standard substance abuse treatment referral list currently in use clinically at each site. The number of assessments and interactions with research staff will remain equal between the two conditions, with the only difference being the active intervention of the DARSSA reports and referrals, and any counseling by healthcare providers this engenders. The remainder of this section describes each phase of the study and enrollment procedures.
The investigators hypothesized that an enriched focus on mother-infant bonding during a newborn's hospitalization in the Neonatal Intensive Care Unit would reduced the rate maternal postpartum smoking relapse and would prolong the duration of breastfeeding in mothers who had quit smoking during or just prior to pregnancy.
