Filter by:Regular aspirin use has been associated with a reduction in the development of a number of different malignancies including lung cancer. The mechanism of aspirin's cancer prevention is not known. This study will evaluate whether once daily aspirin use can reduce the production of a protein named prostaglandin E2 (PGE-2), which is known to promote cancer. Specifically, this study will evaluate if aspirin can inhibit the production of PGE-2 by blocking an enzyme named cycloxygenase-2 (COX-2). To accomplish these goals, participants will take either aspirin 325 mg daily, celecoxib 200 mg twice daily, or the combination of both during various days of this 16-day study. Urine be collected to evaluate for PGE-2 production at 4 timepoints in this 16-day study.
This study tests whether pre-cessation interventions known to be effective in the general population will increase acceptance of evidence-based treatment, engagement and compliance with that treatment and initial quitting success. One hundred and seventy two patients will be recruited from 13 Community Support Programs (CSPs). CSPs provide community based care to those diagnosed with persistent and serious mental illness. All participants will receive two group sessions (40 minutes each) modeled after "Kicking Butts", a group-based quitting preparation program used for the past four years in two Milwaukee CSP programs run by Wisconsin Community Services. Individuals will then be randomly assigned to the experimental and control conditions (n=86 each). Experimental subjects will receive four evidence-based preparatory interventions (motivational interviewing, smoking reduction, practice quit attempt, and pre-quit use of nicotine replacement medication) (25 - 30 minutes each). Attention control subjects will also receive four individual sessions of the same duration. However their individual sessions' content will be a discussion of the personal relevance of the group material and will not include any of the preparatory interventions. Data will be collected via brief surveys taken pre-intervention, at the end of the last individual session, and three months later and from a database provided by the Wisconsin Tobacco Quit Line (WTQL).
Innovative strategies to reduce adult smoking prevalence include using genetic information to motivate cessation and, ultimately, to tailor cessation pharmacotherapy. Success of these interventions depends, in part, on smokers' interest and participation in genetic testing related to cessation and their understanding and use of the results (i.e., their genetic literacy). The recent availability of genetic risk testing for a nicotinic acetylcholine receptor gene (CHRNA3) variant (rs105173) associated with nicotine dependence makes it highly feasible to investigate smokers' interest in and use of genetic information about nicotine dependence. Therefore, the primary purpose of this study is to determine the impact of an intervention that provides smokers with an educational session about genetic contributions to smoking and nicotine dependence plus their genotype results for rs1051730 on smoking cessation outcomes compared to those who receive only the educational session. Secondary purposes are to determine: (a) the impact of genetic education and knowing personal genotype results on genetic literacy outcomes and (b) the feasibility of recruitment and retention methods in a study addressing genotyping for nicotine dependence. Primary outcomes are cessation-related behaviors and cognitions indicating abstinence. Secondary outcomes are cognitions and emotions indicating genetic literacy. Knowledge gained from this study has the potential for clinical translation so that as genotyping becomes part of smoking cessation, health-care providers can understand and address factors influencing smokers' adaptation to genetically-informed cessation treatment. The study will use a longitudinal, repeated measures design (experimental, control; N=90; 45/group). All participants will receive a 90-minute educational session about genetic contributions for smoking and nicotine dependence and will donate a buccal swab sample for genotyping. The investigators will then randomize participants to two groups: those who receive genotyping results in a genetic counseling session (experimental) and those who do not (control). Follow-up data will be collected from both groups at baseline and weeks 2, 6, 10 after the experimental group receives genotyping results, with a brief follow-up and study termination occurring at week 12. Control group participants will be offered their genotyping results at the end of the study.
This pilot clinical trial studies varenicline or nicotine patch in promoting smoking cessation among current smokers. Varenicline or nicotine patch may help people stop smoking
Upwards of 33-50% of cancer patients who smoked prior to diagnosis continue to smoke following diagnosis and treatment. With medical advances in cancer care yielding a growing constituency of cancer survivors, addressing nicotine dependence in this population is a priority. While PHS guidelines recommend acute treatment durations with approved medications for tobacco use, extending the duration of treatment beyond the standard treatment duration significantly increases quit rates, reduces the risk for a relapse, and promotes recovery to abstinence following a lapse. Varenicline may be particularly effective for cancer patients given the drug's beneficial effects on affect and cognition. In this trial, 374 cancer patients will be randomized to standard varenicline treatment (12 weeks active + 12 weeks placebo) or extended varenicline treatment (24 weeks active). The investigators hypothesize that 1) Extended varenicline therapy will increase 24- and 52-week biochemically-confirmed abstinence versus standard varenicline treatment, 2) Quality of life will be rated higher in the extended therapy group versus the standard therapy group, and there will be no significant differences between groups in terms of severe side effects, and 3) Improved affect and reduced cognitive impairment will mediate the effect of extended therapy on quit rates.
The study's primary aim is to test the hypothesis that an intervention integrating pediatric clinic-level quality improvement with home-level behavioral counseling (CQI+BC) will result in greater reductions in child cotinine (a biomarker of secondhand smoke exposure) and reported cigarettes exposed/day than a clinic-level quality improvement plus attention control intervention (CQI+A). A secondary aim is to test the hypothesis that relative to CQI+A, CQI+BC will result in higher cotinine-verified, 7-day point prevalence quit rate among parents.
The aim of the present study is to compare cognitive scores (attention, executive function and working memory) of different e-Cigarette strength with usual cigarettes.
Aim: To identify barriers and facilitators in the uptake of smoking cessation pharmacotherapies, tobacco prevention, doctor visits, smoking amongst youth, community held health priorities and barriers to research in Aboriginal Australians from the perspectives of: - Aboriginal smokers and ex/non-smokers - Aboriginal Healthcare workers - Consultants/general practitioners, and - Key stakeholders in Aboriginal health Focus groups, one-on-one interviews and surveys will be conducted to provide information at the 'grass-roots' level including examinations into perceived differences in locally held beliefs, attitudes, knowledge, traditional practices and the cultural and social constructs, to assist implementation of future tobacco cessation/prevention interventions and treatment of smoking related illnesses. This information can be used to improve the health of Aboriginal people by identifying inadequacies in current practices and highlighting what these are through the eyes of community members, healthcare workers, consultants/general practitioners and key stakeholders. We also intend on examining any facilitators that are identified as positive and working aspects of current initiatives e.g. community infrastructure, in an effort to not 'reinvent the wheel' and acknowledge what is working.
Nicotine dependence may prolong the exposure to toxic substances that cause various diseases. The Central Nervous System (CNS) is consisted by a large amount of Polyunsaturated Fatty Acids (PUFAS) from omega-3 serie. Omega-3 takes part in several actions, including the modulation of dopaminergic neurotransmission. In its deficiency is detected a hypofunctioning of the mesolimbic and mesocortical pathway, related to the reward system, involved on the context of nicotine dependence. Treatment using dietary supplementation with omega-3 shows improvements in several diseases, including mood disorders such as anxiety and depression. The investigators hypothesis is that supplementation with these fatty acids can restore the levels of omega-3 and could decrease nicotine dependence. The investigators objective is to investigate a possible association between increased serum levels of omega-3 and the reduction in nicotine dependence.
Cigarette smoking is the leading preventable cause of death in the U.S. The 2008 US Public Health Service Smoking Cessation Guideline recommends offering effective treatment to smokers in all health care settings, including hospitals. Nearly 4 million smokers are hospitalized each year, and hospital admission offers a "teachable moment" for intervention. Hospital-initiated smoking cessation intervention is effective, but only if contact continues for more than 1 month after discharge. The challenge is to translate this research into clinical practice by identifying an evidence-based cost-effective model that U.S. hospitals can adopt. The major barrier is sustaining contact after discharge. This project tests an innovative strategy to streamline the delivery and maximize the uptake of post-discharge smoking interventions. Specific Aim: To test the effectiveness of an innovative strategy to maximize smokers' use of evidence-based tobacco treatment (counseling and medication) after hospital discharge, thereby increasing the proportion of smokers who achieve long-term (6-month) tobacco abstinence. Study Design: A multi-site randomized controlled comparative effectiveness trial will enroll 1350 adult smokers admitted to 3 acute care hospitals in Massachusetts and Pennsylvania. All subjects will receive a brief in-hospital smoking intervention and be randomly assigned at discharge to either Standard Care (passive referral to their state quitline) or Extended Care, a 3-month program consisting of (1) Free Medication: A 30-day supply of FDA-approved medication (nicotine replacement, bupropion, or varenicline) given at hospital discharge and refillable for a total of 90 days to encourage medication use and adherence; (2) Interactive Voice Response (IVR) Triage to Telephone Counseling from a national quitline provider. IVR aims to encourage medication adherence and enhance counseling efficiency by identifying smokers who need post-discharge support. Immediate transfer of a patient from automated IVR call to live telephone counselor will facilitate a successful connection to counseling. Outcomes, assessed at 1, 3, and 6 months after hospital discharge, are: (1) intervention effectiveness (cotinine-validated 7-day point-prevalence tobacco abstinence rate at 6 month follow-up [primary outcome] and other tobacco abstinence measures); (2) treatment utilization, and (3) cost-effectiveness (cost per quit). Exploratory analyses will examine the intervention's effect on hospital readmissions and mortality in the 6 months after discharge.
