Quitting smoking and aerobic exercise each improve health. Although smokers may be concerned that quitting smoking will reduce their quality of life (QOL), recent research has shown that cessation is associated with QOL benefits. Elements of smoking cessation interventions, such as exercise, may contribute to changes in QOL. However, it is unknown whether initiating exercise in the context of smoking cessation is associated with greater or different effects on QOL than smoking cessation alone. The current study is a secondary analysis of data from a randomized trial (n = 61) of an exercise intervention for smoking cessation...

BACKGROUND: Individuals in the criminal justice system demonstrate high rates of cigarette use (70-80%) and low adherence to smoking cessation medication. Educational approaches have not been shown to promote adherence or cessation, though medication sampling has boosted both use and cessation. The objective of the present study was to determine whether In vivo nicotine replacement therapy (NRT) sampling approach increases NRT adherence among criminal justice smokers during a subsequent quit attempt...

INTRODUCTION: There is growing evidence that the mailed distribution of free nicotine replacement therapy (NRT), usually as part of smokers' helplines, can been effective in increasing the odds of cessation on a population level. However, limited information is available on the utilization of NRT when it is provided for free, and factors associated with regimen adherence have remained largely unexplored. METHODS: In the context of a randomized controlled trial, 500 adult smokers across Canada hypothetically interested in free NRT were mailed a 5week supply of nicotine patches, but no other support was offered...

BACKGROUND: The development of tobacco use treatments that are effective for all smokers is critical to improving clinical and public health. The Multiphase Optimization Strategy (MOST) uses highly efficient factorial experiments to evaluate multiple intervention components for possible inclusion in an optimized tobacco use treatment. Factorial experiments permit analyses of the influence of patient characteristics on main and interaction effects of multiple, relatively discrete, intervention components...

BACKGROUND: Understanding how smoking cessation treatments exert their effects can inform treatment development and use. Factorial designs allow researchers to examine whether multiple intervention components affect hypothesized change mechanisms, and whether the affected mechanisms are related to cessation. METHODS: This is a secondary data analysis of smokers recruited during primary care visits (N=637, 55% women, 87% white) who were motivated to quit. Participants in this fractional factorial experiment were randomized to one level of each of six intervention factors: Prequit Nicotine Patch vs None, Prequit Nicotine Gum vs None, Preparation Counseling vs None, Intensive In-Person Counseling vs Minimal, Intensive Phone Counseling vs Minimal, and 16 vs 8 Weeks of Combination Nicotine Replacement (nicotine patch+nicotine gum)...

The american cockroach (Periplaneta americana) dorsal unpaired median (DUM) neurons provide an native tool to analyze the functional and pharmacological properties of ion channels and membrane receptors, such as nicotine acetylcholine receptors (nAChRs). Here the imidacloprid-activated nAChR subtypes were examined in DUM neurons by the patch-clamp technique and the potential subunits involved in important subtypes were analyzed by combining with RNA interference (RNAi) technique. Imidacloprid exerted agonist activities on one subtype in α-Bgt-sensitive nAChRs and another subtype in α-Bgt-resistant nAChRs, in which the α-Bgt-resistant subtype showed much higher sensitivity to imidacloprid than the α-Bgt-sensitive subtype, with the difference close to 200-fold...

Purpose Prisoners are vulnerable to tobacco addiction and have a smoking prevalence significantly higher than that of the general community. The context of this study was the implementation of a "smoke-free prisons" policy, which imposed forced smoking cessation onto the Queensland, Australian prison population. The study asked the question: "What are the psychosocial processes in which male prisoners engage during smoking cessation in a smoke-free environment?" Design/methodology/approach Qualitative interviews were conducted with 15 prisoners in South-east Queensland smoke-free correctional centres...

BACKGROUND AND OBJECTIVE: Relative effectiveness of smoking cessation medications-varenicline, bupropion and nicotine replacement therapy (NRT)-remains unclear among smokers in real-world settings. Evidence in females and smokers with light/moderate nicotine dependence is particularly insufficient. This study compared the effectiveness of varenicline, bupropion or NRT gum relative to NRT patch, in achieving abstinence among recent quitters. METHODS: In a national smoking cessation program in Taiwan (2012-2015), a cohort of 11,968 participants received varenicline (n = 5,052), bupropion (n = 823), NRT gum (n = 1944) or NRT patch (n = 4,149)...

BACKGROUND: Variation in the CYP2A6 gene alters the rate of nicotine metabolic inactivation and is associated with smoking behaviors and cessation success rates. The underlying neurobiological mechanisms of this genetic influence are unknown. METHODS: Intrinsic functional connectivity strength, a whole-brain, data-driven, graph theory-based method, was applied to resting-state functional magnetic resonance imaging data in 66 smokers and 92 nonsmokers. A subset of subjects (n = 23/20; smokers/nonsmokers) performed the monetary incentive delay task, probing reward anticipation, and a go/no-go task, probing response inhibition, on two occasions, in the presence and absence of a nicotine patch...

Tobacco smoking is a public health problem, with ∼5 million deaths per year, representing a heavy burden for many countries. No effective therapeutic strategies are currently available for nicotine addiction, and it is therefore crucial to understand the etiological and pathophysiological factors contributing to this addiction. The neuronal α5 nicotinic acetylcholine receptor (nAChR) subunit is critically involved in nicotine dependence. In particular, the human polymorphism α5D398N corresponds to the strongest correlation with nicotine dependence risk found to date in occidental populations, according to meta-analysis of genome-wide association studies...

The neuropeptide PACAP modulates synaptic transmission in the hippocampus exerting multiple effects through different receptor subtypes: the underlying mechanisms have not yet been completely elucidated. The neurotransmitter acetylcholine (ACh) also exerts a well-documented modulation of hippocampal synaptic transmission and plasticity. Since PACAP was shown to stimulate ACh release in the hippocampus, we tested whether PACAP acting through ACh might indirectly modulate glutamate-mediated synaptic transmission at a pre- and/or at a post-synaptic level...

Varenicline is a nicotinic acetylcholine receptor (nAChR) agonist used to treat nicotine addiction, but a live debate persists concerning its mechanism of action in reducing nicotine consumption. Although initially reported as α4β2 selective, varenicline was subsequently shown to activate other nAChR subtypes implicated in nicotine addiction including α3β4. However, it remains unclear whether activation of α3β4 nAChRs by therapeutically relevant concentrations of varenicline is sufficient to affect the behavior of cells that express this subtype...

INTRODUCTION: The study estimated the prevalence of unassisted quitting (ie, quitting without pharmacological aids or other interventions) among former smokers and identified the most common smoking cessation methods used by U.S. adult smokers who quit smoking between 2007 and 2011. Among long-term quitters, smoking-related behaviors and factors associated with using pharmacological methods and quitting unassisted were examined. METHODS: The analytic sample consisted solely of former smokers, including 3,583 "long-term quitters" (those who quit 1 to 3 years prior to the survey) and 2,205 "recent quitters" (those who quit within a year prior to the survey), who responded to the 2010-2011 Tobacco Use Supplement to the Current Population Survey...

The use of electronic cigarettes (e-cigarettes) is increasing, but their use as a smoking-cessation aid is controversial. The reporting of e-cigarette studies on cessation is variable and inconsistent. To date, only 1 randomized clinical trial has included an arm with other cessation methods (nicotine patches). The cessation rates for available clinical trials are difficult to compare given differing follow-up periods and broad ranges (4% at 12 months with non-nicotine e-cigarettes to 68% at 4 weeks with concomitant nicotine e-cigarettes and other cessation methods)...

INTRODUCTION: Quitlines (QL) are an effective means for smoking cessation, but a paucity of data exist examining the dose-response relationship between use of QL services and quit rates, especially among low-income smokers. The purpose of this study was to study the relationship between tobacco abstinence and use of QL services among low-income smokers. METHODS: Secondary analysis of a randomized trial of every- or some-day smokers aged 18 years or older visiting an urban emergency department...

INTRODUCTION: Individuals who use the nicotine patch are more likely to quit smoking than those who receive placebo or no medication. However, studies have not yet examined the association between actual daily nicotine patch wear time during the early phase of a smoking cessation attempt and later smoking abstinence. The purpose of this study was to address this gap in the literature. METHODS: Participants who enrolled in a safety-net hospital smoking cessation program were followed for 13 weeks (i...

Approximately 80,000 New York City smokers are Chinese or Russian speakers. To increase utilization of smoking cessation services among these populations, the Department of Health and Mental Hygiene developed linguistically and culturally tailored outreach strategies to promote and enhance its annual Nicotine Patch and Gum Program. In 2010, online web applications in Chinese and Russian were introduced. In 2011, input was sought from the community to develop Russian-language radio and newspaper ads, and a Russian-speaking liaison provided phone-assisted online enrollment support...
