Filter by:To evaluate the comparative effectiveness of extrafine hydrofluoroalkane beclometasone (EF HFA-BDP) and other inhaled corticosteroid (ICS) therapy commonly used in the UK, specifically fluticasone (FP) and non-extrafine (NEF) BDP (CFC-BDP and NEF HFA-BDP) in a UK primary care asthma population of current smokers.
To examine the influence of current daily tobacco smoking on brain activation during stress, tobacco cue, and neutral relaxing conditions
This project is prompted by the urgent public health need to identify novel strategies to prevent and treat tobacco-related cardiovascular disease (CVD) and by compelling pilot data that suggests cessation of smoking results in rapid amelioration of endothelial function. The higher prevalence of CVD and metabolic syndrome in smokers have become major health care concerns. Therefore, finding optimal intervention strategies to combat these growing epidemics is imperative. We are investigating the efficacy of resistance training to ameliorate endothelial dysfunction, oxidative stress, inflammation, and insulin resistance in four groups: presence or absence of resistance training with or without cessation treatment + nicotine replacement. The investigators hypothesize that resistance training will improve cardiovascular function in smokers; however, the responses will be better in those who also stop smoking. In addition, resistance training will decrease smoking, however, the effects of counseling and nicotine replacement alone or counseling and nicotine replacement in conjunction with resistance training will be better than resistance training alone.
Bioequivalence study to confirm that a NTS with a polyisobutylene (PIB) adhesive from an alternative supplier delivers the same nicotine blood profile as that of the currently approved NTS with a polyisobutylene adhesive from the current supplier.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the bronchi with an increasing prevalence. By 2020, the mortality related to COPD is expected to become the 3rd leading death worldwide. COPD is caused by smoking in approximately 90 % of the cases. Nevertheless, COPD remains under-diagnosed and more than half of patients remain active smokers. Brittany is the second region of France facing an abnormal high death rate related to COPD. Smoking cessation is the most effective therapeutic approach to reduce the evolution of the disease, the frequency of the exacerbations and the the mortality. Besides, smoking cessation is associated with a reduced risk of cardiovascular events and cancer. Given the COPD patients' strong addiction, smoking cessation is not easily obtained in such population. Furthermore, smoking cessation has been underestimated in several studies. Most of these studies evaluated various methods of smoking cessation in COPD patients performed after an exacerbation, which has a hospitalization related mortality of approximately 10%. Thus, there is an urgent need to find effective pharmacotherapies to help COPD patients to cease smoking. Varenicline, a partial agonist at a4ß2 nicotinic acetylcholine receptors is reported to be one of the most effective pharmacotherapies for smoking cessation. However, it has never been evaluated at the acute phase of an exacerbation of COPD requiring hospitalization.
This study will implement and test the effectiveness and cost-effectiveness of a tobacco cessation intervention (Academic Detailing + Integrated Tobacco Order Set - AD + ITOS) for adults admitted to the hospital. The intervention will begin during the hospital stay and continue after discharge. The intervention will use resources easily available to most acute care hospitals: computerized physician order entry, physician and nurse education, staff meetings for physicians, nurses and allied health professionals, online learning capabilities, faxing to primary care providers (PCPs), and the telephone counseling and support available from a state smokers' quitline (QL). The investigators hypothesize that the subjects in the intervention arm (AD + ITOS) will be more likely to achieve tobacco abstinence at 12 months post hospital stay than subjects in the control arm (Academic Detailing - AD). Tobacco abstinence will be assessed by self report and biochemical verification (exhaled carbon monoxide reading).
Tobacco use is the number one killer of Americans today. Most current smokers have tried and failed to quit at least once. Smokers are addicted to the nicotine in tobacco products, and withdrawal from smoking can lead to physical symptoms such as irritability, anxiety, nervousness, depression and insomnia. This study will examine the effects of tobacco cessation counseling and chiropractic treatments on smokers who desire to quit.
Little is known about what factors influence parental decisions to participate or to decline participation in tobacco trials offered in the pediatric clinical setting. Further, it is unclear what proportion of parents treated in our setting would elect to receive formal assistance with quitting smoking or consider alternative approaches that could facilitate eventual smoking cessation. While the recommendation to parents is generally to quit smoking, some may be unwilling or unable to quit and prefer more achievable alternative treatment goals. Some parent smokers may be unlikely to participate in an intervention aimed only at cessation but would be willing to participate in an intervention focused on establishing smoke-free environments for their child. Parents are typically not offered a choice regarding the type of intervention they receive and many interventions are not tailored to their readiness to quit smoking or designed to reach multiple family members in the home who may also smoke. Quitting smoking and establishing smoke-free homes and cars are distinct, yet challenging, goals for parents and families. Both approaches can directly, or indirectly, help parents to quit smoking, reduce the child's exposure to second-hand smoke (SHS), and initiate an important dialogue with families about tobacco control. How parental acceptability of smoking interventions is affected by the context of their child's treatment for cancer or SCD, as well as survivorship, warrants further study.
The purpose of this study is to determine the safety and tolerability of multiple doses of PF-05402536 and PF-06413367 in healthy adult smokers.
Periodontal wound healing is a complex multifactorial process that involves interactions among various cells, growth factors, hormones and extracellular matrices. Although still poorly understood, these interactions trigger a series of events that lead to new tissue formation. One growth factor that plays an important role in wound healing is fibroblast growth factor 2 (FGF2). Many animal and human studies have shown this protein is effective in periodontal regeneration. Recently, epigenetic modifications, such as DNA methylation, have been associated with changes in patterns of gene expression. Preliminary data suggests that FGF2 gene may be differentially methylated in periodontal tissues. Aberrant gene promoter methylation in smokers and diabetics has also been reported in many studies. However, the role of DNA methylation in wound healing has not yet been investigated. The investigators hypothesize that the methylation status of FGF2 gene can affect the levels of FGF2 secreted during wound healing phase after dental implant surgery. The investigators also hypothesize there exists a difference in methylation levels of FGF2 gene in healthy, smoking and diabetic patients that can interfere with wound healing. The investigators seek to determine whether DNA methylation plays a role in wound healing and whether the methylation level of FGF2 gene varies among healthy, smoking and diabetic patients.
