Herman RJ, Schmidt HD. Targeting GLP-1 receptors to reduce nicotine use disorder: Preclinical and clinical evidence. Physiol Behav 2024; 281:114565. [PMID: 38663460 PMCID: PMC11128349 DOI: 10.1016/j.physbeh.2024.114565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/18/2024] [Accepted: 04/22/2024] [Indexed: 04/30/2024]
Abstract
Nicotine use disorder (NUD) remains a leading cause of preventable death in the U.S. Unfortunately, current FDA-approved pharmacotherapies for smoking cessation have limited efficacy and are associated with high rates of relapse. One major barrier to long-term smoking abstinence is body weight gain during withdrawal. Nicotine withdrawal-induced body weight gain can also lead to development of chronic disease states like obesity and type II diabetes mellitus. Therefore, it is critical to identify novel pharmacotherapies for NUD that decrease relapse and nicotine withdrawal symptoms including body weight gain. Recent studies demonstrate that glucagon-like peptide-1 receptor (GLP-1R) agonists attenuate voluntary nicotine taking and seeking and prevent withdrawal-induced hyperphagia and body weight gain. Emerging evidence also suggests that GLP-1R agonists improve cognitive deficits, as well as depressive- and anxiety-like behaviors, which contribute to smoking relapse during withdrawal. While further studies are necessary to fully characterize the effects of GLP-1R agonists on NUD and understand the mechanisms by which GLP-1R agonists decrease nicotine withdrawal-mediated behaviors, the current literature supports GLP-1R-based approaches to treating NUD.

Addict Biol 2023; 28:e13303. [PMID: 37500482 DOI: 10.1111/adb.13303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 04/21/2023] [Accepted: 05/30/2023] [Indexed: 07/29/2023]
Abstract
To evaluate the effectiveness, safety and tolerability of antidepressants in helping smokers quit tobacco dependence, five databases were searched for randomized controlled trials (RCTS ) on different antidepressant interventions involving smoking cessation in populations (September 2022). The STATA 15.1 software was used to perform network meta-analysis. The Cochrane bias risk tool was used to assess the risk of bias, and CINeMA was used to evaluate the evidence credibility for the effect of different interventions on smoking cessation. In all, 107 RCTs involving 42 744 patients were included. Seven studies were rated as having a low risk of bias. All trials reported 18 interventions and 153 pairwise comparisons were generated. The network meta-analysis showed that compared with placebo, varenicline + bupropion (OR = 3.53, 95% CI [2.34, 5.34]), selegiline + nicotine replacement therapy (NRT) (OR = 3.78, 95% CI [1.20, 11.92]), nortriptyline + NRT (OR = 2.33, 95% CI [1.21, 4.47), nortriptyline (OR = 1.58, 95% CI [1.11,2.26]), naltrexone + bupropion (OR = 3.84, 95% CI [1.39, 10.61]), bupropion + NRT (OR = 2.29, 95% CI [1.87, 2.81]) and bupropion (OR = 1.70, 95% CI [1.53, 1.89]) showed benefits with respect to smoking cessation. In addition, bupropion + NRT showed better effects than bupropion (OR = 1.35, 95% CI [1.12, 1.64]) and NRT (OR = 1.38, 95% CI [1.13, 1.69]) alone. The final cumulative ranking curve showed that varenicline + bupropion was the most likely to be the best intervention. There was moderate- to very-low-certainty evidence that most interventions showed benefits for smoking cessation compared with placebo, including monotherapy and combination therapies. Varenicline + bupropion had a higher probability of being the best intervention for smoking cessation.

Randomized double-blind placebo-controlled multicenter trial for the effects of a polyherbal remedy, Yokukansan (YiganSan), in smokers with depressive tendencies. BMC Complement Med Ther 2022; 22:311.

Abstract
BACKGROUND Smoking and depression are closely related and form a vicious cycle. Yokukansan (YiganSan) is a polyherbal remedy that has the effect of calming neuropsychiatric symptoms such as anger and irritation. To examine the efficacy of Yokukansan during smoking cessation (SC) therapy in smokers with depressive tendencies but without major depressive disorders requiring pharmacotherapy. METHODS A multicenter, double-blind, randomized, placebo-controlled, parallel-group comparison trial was conducted between June 2016 and May 2020 at 12 centers of the National Hospital Organization, Japan. This trial targeted smokers who first visited the SC outpatient clinics, did not receive any pharmacological treatment at the psychiatric or psychosomatic department, and scored 39 or more on the self-rating depression scale (SDS). Participants (n = 198) were randomly assigned to either the Yokukansan or placebo groups. The trial drug was initiated with the start of the SC treatment and continued for 12 weeks. The primary outcome was the high success rate of the SC treatment, and the secondary outcomes included changes in scores of the SDS and the Profile of Mood States (POMS) instrument. RESULTS The success rate of the SC treatment was similar between the placebo (63%) and Yokukansan (67%) groups (P = .649). The SDS scores (placebo: mean difference [MD] = -3.5, 95% confidence interval [CI][-5.8, -1.2], d = 0.42; Yokukansan: MD = -4.6, 95%CI[-6.8, -2.3], d = 0.55), and the "tension-anxiety" POMS-subscale scores (placebo: MD = -1.6, 95%CI[-2.5, -0.7], d = 0.52; Yokukansan: MD = -1.6, 95%CI[-2.9, -0.3], d = 0.36) showed significant improvement in both groups after the SC treatment. However, "depression-dejection" improved in the Yokukansan group (MD = -1.9, 95%CI[-3.1, -0.7], d = 0.44) but not in the placebo group (MD = -0.1, 95%CI[-1.0, 0.7], d = 0.04). Significant improvement in "fatigue" was noted in the Yokukansan group (MD = -2.1, 95%CI[-3.4, -0.9], d = 0.47) but not in the placebo group (MD = -0.5, 95%CI[-1.8, 0.8], d = 0.11). The time × group interaction on the improvement in "depression-dejection" was significant (P = .019). CONCLUSIONS Yokukansan does not increase the SC treatment's success rate but has additional positive effects on the psychological states due to the SC treatment in smokers with depressive tendencies but without apparent mental disorders.

Evaluating the effectiveness of bupropion and varenicline for smoking cessation using an internet-based delivery system: A pragmatic randomized controlled trial (MATCH study). Drug Alcohol Depend 2022; 232:109312. [PMID: 35151504 DOI: 10.1016/j.drugalcdep.2022.109312] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 12/21/2021] [Accepted: 01/10/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND Traditional randomized controlled trials have demonstrated the efficacy of pharmacotherapy for smoking cessation. However, accessibility to treatments remains a barrier, necessitating the remote delivery of evidence-based cessation interventions. The aim of this study was to evaluate the effectiveness of an online treatment that included first-line prescription medications using a pragmatic randomized controlled trial design. METHODS This study was a two-group, parallel block randomized, open label, controlled trial, and conducted exclusively online. Participants were randomised (1:1) to either bupropion (150 mg) or varenicline (1 mg) for twelve weeks. Medication was couriered to participants. The primary outcome was 7-day point prevalence abstinence (PPA; defined as 0 cigarette puffs in the last 7 days) at 12 weeks. Secondary outcomes were 7-day PPA at 4-, 8-, 26-, and 52-weeks follow-up. Adverse events were evaluated at each follow-up session during treatment. RESULTS The varenicline group (n = 499) had significantly higher 7-day PPA (30.3%) compared to the bupropion group (n = 465; 19.6%) at end of treatment (OR=2.08, 95% CI: 1.49-2.90, p < 0.001). Seven-day PPA was also higher for the varenicline group at 4-weeks (OR=1.71, 95% CI: 1.23-2.40 p = 0.0001), and 8-weeks follow-up (OR=1.95, 95% CI: 1.43-2.67 p < 0.0001), but not at post-treatment follow-up. More adverse events were reported in the varenicline group, compared to bupropion. CONCLUSIONS This internet-based pharmacotherapy intervention was a feasible and effective method of treatment delivery for smoking cessation. This method can be used to increase the accessibility and availability of cessation interventions, decreasing the burden of smoking-related diseases.

Abstract
BACKGROUND Past studies have established the association of CHRNA5-A3-B4 gene cluster variants with various smoking behaviors in different ethnicities, yet no such study has been reported in Bengali ethnicity to date. METHODS A case-control study with 129 smokers and 111 non-smokers was conducted and genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method aimed to manifest the association of three SNPs in this gene cluster with smoking status (SS) in a Bangladeshi population. RESULTS The non-synonymous CHRNA5 rs1s6969968 and 3'-UTR variant CHRNA3 rs578776 polymorphisms were found to have a strong association with SS. Carriers of polymorphic 'A' allele of rs16969968 showed 1.51-fold more risk of being smokers (adjusted OR = 1.51, 95% CI 0.88-2.57, p = 0.128); whereas, rs578776 polymorphic 'A' allele carriers showed 0.595-fold less risk of being smokers (adjusted OR = 1.51, 95% CI 0.88-2.57, p = 0.006). Comparing smokers and non-smokers, A/A mutant homozygous genotypes of rs578776 and rs16969968 variants pose 0.369-fold (95% CI 0.177-0.77, p = 0.008) and 3.3-fold (95% CI 0.66-16.46, p = 0.14) more risk for positive SS, respectively. No genotypic association for SS was found with intronic variant CHRNB4 rs11072768 (T/G; adjusted OR = 0.827, 95% CI 0.457-1.499, p = 0.532 and G/G; adjusted OR = 0.992, 95% CI 0.455-2.167, p = 0.985). Combination of rs16969968-positive/rs578776-negative polymorphic variants possesses the risk of positive SS in young adults. Furthermore, two new haplotypes (AAT and AAG) were identified in Bangladeshi population and GAG (OR = 0.45, 95% CI 0.25-0.8, p = 0.006) haplotype was found to be a protective factor for SS. CONCLUSION Nicotinic acetylcholine gene cluster CHRNA5-A3-B4 variants rs16969968 and rs578776 are associated with SS in a Bangladeshi population. Large-scale studies are warranted to establish this genotype-phenotype correlation.

Abstract
Tobacco use is the greatest threat to public health worldwide, killing more than seven million people annually. This paper, about 10 years after the first review on electronic cigarettes, analyses the evolution that this tool has had in these years. It concludes with comments on the significance of the research and why it constitutes an original contribution. We searched PubMed (National Library of Medicine), and PsycINFO (Ovid) (2006-2020) for studies on e-cigarettes (harms and benefits, e-cigarette use, craving and smoking cessation) and smoking cessation treatment (smoking cessation treatment or varenicline or tobacco cessation or reduction or bupropion or NRT or behavioral treatment or ecigarette) and evidence suggests that they may effective as smoking cessation tool and may be less harmful alternatives to combustible cigarette smoking. Consequently, e-cigarettes could be considered as an applicable instrument for Tobacco Harm Reduction (THR) and smoking cessation.

Abstract
BACKGROUND There is a high prevalence of smoking among people with severe mental ill health (SMI). Helping people with SMI to quit smoking could improve their health and longevity, and reduce health inequalities. However, those with SMI are less likely to access and engage with routine smoking cessation services than the general population. OBJECTIVES To compare the clinical effectiveness and cost-effectiveness of a bespoke smoking cessation (BSC) intervention with usual stop smoking services for people with SMI. DESIGN A pragmatic, two-arm, individually randomised controlled trial. SETTING Primary care and secondary care mental health services in England. PARTICIPANTS Smokers aged ≥ 18 years with SMI who would like to cut down on or quit smoking. INTERVENTIONS A BSC intervention delivered by mental health specialists trained to deliver evidence-supported smoking cessation interventions compared with usual care. MAIN OUTCOME MEASURES The primary outcome was self-reported, CO-verified smoking cessation at 12 months. Smoking-related secondary outcomes were self-reported smoking cessation, the number of cigarettes smoked per day, the Fagerström Test for Nicotine Dependence and the Motivation to Quit questionnaire. Other secondary outcomes were Patient Health Questionnaire-9 items, Generalised Anxiety Disorder Assessment-7 items and 12-Item Short-Form Health Survey, to assess mental health and body mass index measured at 6 and 12 months post randomisation. RESULTS The trial randomised 526 people (265 to the intervention group, 261 to the usual-care group) aged 19 to 72 years (mean 46 years). About 60% of participants were male. Participants smoked between 3 and 100 cigarettes per day (mean 25 cigarettes per day) at baseline. The intervention group had a higher rate of exhaled CO-verified smoking cessation at 6 and 12 months than the usual-care group [adjusted odds ratio (OR) 12 months: 1.6, 95% confidence interval (CI) 0.9 to 2.8; adjusted OR 6 months: 2.4, 95% CI 1.2 to 4.7]. This was not statistically significant at 12 months (p = 0.12) but was statistically significant at 6 months (p = 0.01). In total, 111 serious adverse events were reported (69 in the BSC group and 42 in the usual-care group); the majority were unplanned hospitalisations due to a deterioration in mental health (n = 98). The intervention is likely (57%) to be less costly but more effective than usual care; however, this result was not necessarily associated with participants' smoking status. LIMITATIONS Follow-up was not blind to treatment allocation. However, the primary outcome included a biochemically verified end point, less susceptible to observer biases. Some participants experienced difficulties in accessing nicotine replacement therapy because of changes in service provision. Efforts were made to help participants access nicotine replacement therapy, but this may have affected participants' quit attempt. CONCLUSIONS People with SMI who received the intervention were more likely to have stopped smoking at 6 months. Although more people who received the intervention had stopped smoking at 12 months, this was not statistically significant. FUTURE WORK Further research is needed to establish how quitting can be sustained among people with SMI. TRIAL REGISTRATION Current Controlled Trials ISRCTN72955454.

Abstract
Smoking is the leading preventable cause of death worldwide and tobacco addiction has become a serious public health problem. Nicotine is the main addictive component of tobacco, and the majority of people that smoke regularly develop nicotine dependence. Nicotine addiction is deemed to be a chronic mental disorder. Although it is well known that nicotine binds to the nicotinic acetylcholine receptors (nAChRs) and activates the mesolimbic dopaminergic system (MDS) to generate the pleasant and rewarding effects, the molecular mechanisms of nicotine addiction are not fully understood. Brain-derived neurotrophic factor (BDNF) is the most prevalent growth factor in the brain, which regulates neuron survival, differentiation, and synaptic plasticity, mainly through binding to the high affinity receptor tyrosine kinase receptor B (TrkB). BDNF gene polymorphisms are associated with nicotine dependence and blood BDNF levels are altered in smokers. In this review, we discussed the effects of nicotine on BDNF expression in the brain and summarized the underlying signaling pathways, which further indicated BDNF as a key regulator in nicotine dependence. Further studies that aim to understand the neurobiological mechanism of BDNF in nicotine addcition would provide a valuable reference for quitting smoking and developing the treatment of other addictive substances.

Abstract
This narrative review focuses on the topic of tobacco smoking amongst people with schizophrenia spectrum disorders. We searched PubMed, PsycInfo and Scopus databases for schizophrenia spectrum disorders and smoking and included articles about the epidemiology of tobacco smoking in people with schizophrenia spectrum disorders, examining the relationship between smoking and mental health. This narrative review describes that a higher prevalence, frequency and impact of both high nicotine dependence and its harmful effects in patients with schizophrenia spectrum disorders compared with those in the general population. Despite several existent theories, the reasons for high smoking rates, the high dependence on nicotine and severity of nicotine withdrawal symptoms are not fully understood. The main aim of this paper is to inform mental health personnel and particularly clinical and health psychologists about the impact and role of tobacco smoking for smokers with schizophrenia spectrum disorders.

Abstract
BACKGROUND Whilst the pharmacological profiles and mechanisms of antidepressants are varied, there are common reasons why they might help people to stop smoking tobacco. Firstly, nicotine withdrawal may produce depressive symptoms and antidepressants may relieve these. Additionally, some antidepressants may have a specific effect on neural pathways or receptors that underlie nicotine addiction. OBJECTIVES To assess the evidence for the efficacy, safety and tolerability of medications with antidepressant properties in assisting long-term tobacco smoking cessation in people who smoke cigarettes. SEARCH METHODS We searched the Cochrane Tobacco Addiction Specialized Register, which includes reports of trials indexed in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and PsycINFO, clinicaltrials.gov, the ICTRP, and other reviews and meeting abstracts, in May 2019. SELECTION CRITERIA We included randomized controlled trials (RCTs) that recruited smokers, and compared antidepressant medications with placebo or no treatment, an alternative pharmacotherapy, or the same medication used in a different way. We excluded trials with less than six months follow-up from efficacy analyses. We included trials with any follow-up length in safety analyses. DATA COLLECTION AND ANALYSIS We extracted data and assessed risk of bias using standard Cochrane methods. We also used GRADE to assess the certainty of the evidence. The primary outcome measure was smoking cessation after at least six months follow-up, expressed as a risk ratio (RR) and 95% confidence intervals (CIs). We used the most rigorous definition of abstinence available in each trial, and biochemically validated rates if available. Where appropriate, we performed meta-analysis using a fixed-effect model. Similarly, we presented incidence of safety and tolerance outcomes, including adverse events (AEs), serious adverse events (SAEs), psychiatric AEs, seizures, overdoses, suicide attempts, death by suicide, all-cause mortality, and trial dropout due to drug, as RRs (95% CIs). MAIN RESULTS We included 115 studies (33 new to this update) in this review; most recruited adult participants from the community or from smoking cessation clinics. We judged 28 of the studies to be at high risk of bias; however, restricting analyses only to studies at low or unclear risk did not change clinical interpretation of the results. There was high-certainty evidence that bupropion increased long-term smoking cessation rates (RR 1.64, 95% CI 1.52 to 1.77; I2 = 15%; 45 studies, 17,866 participants). There was insufficient evidence to establish whether participants taking bupropion were more likely to report SAEs compared to those taking placebo. Results were imprecise and CIs encompassed no difference (RR 1.16, 95% CI 0.90 to 1.48; I2 = 0%; 21 studies, 10,625 participants; moderate-certainty evidence, downgraded one level due to imprecision). We found high-certainty evidence that use of bupropion resulted in more trial dropouts due to adverse events of the drug than placebo (RR 1.37, 95% CI 1.21 to 1.56; I2 = 19%; 25 studies, 12,340 participants). Participants randomized to bupropion were also more likely to report psychiatric AEs compared with those randomized to placebo (RR 1.25, 95% CI 1.15 to 1.37; I2 = 15%; 6 studies, 4439 participants). We also looked at the safety and efficacy of bupropion when combined with other non-antidepressant smoking cessation therapies. There was insufficient evidence to establish whether combination bupropion and nicotine replacement therapy (NRT) resulted in superior quit rates to NRT alone (RR 1.19, 95% CI 0.94 to 1.51; I2 = 52%; 12 studies, 3487 participants), or whether combination bupropion and varenicline resulted in superior quit rates to varenicline alone (RR 1.21, 95% CI 0.95 to 1.55; I2 = 15%; 3 studies, 1057 participants). We judged the certainty of evidence to be low and moderate, respectively; in both cases due to imprecision, and also due to inconsistency in the former. Safety data were sparse for these comparisons, making it difficult to draw clear conclusions. A meta-analysis of six studies provided evidence that bupropion resulted in inferior smoking cessation rates to varenicline (RR 0.71, 95% CI 0.64 to 0.79; I2 = 0%; 6 studies, 6286 participants), whilst there was no evidence of a difference in efficacy between bupropion and NRT (RR 0.99, 95% CI 0.91 to 1.09; I2 = 18%; 10 studies, 8230 participants). We also found some evidence that nortriptyline aided smoking cessation when compared with placebo (RR 2.03, 95% CI 1.48 to 2.78; I2 = 16%; 6 studies, 975 participants), whilst there was insufficient evidence to determine whether bupropion or nortriptyline were more effective when compared with one another (RR 1.30 (favouring bupropion), 95% CI 0.93 to 1.82; I2 = 0%; 3 studies, 417 participants). There was no evidence that any of the other antidepressants tested (including St John's Wort, selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs)) had a beneficial effect on smoking cessation. Findings were sparse and inconsistent as to whether antidepressants, primarily bupropion and nortriptyline, had a particular benefit for people with current or previous depression. AUTHORS' CONCLUSIONS There is high-certainty evidence that bupropion can aid long-term smoking cessation. However, bupropion also increases the number of adverse events, including psychiatric AEs, and there is high-certainty evidence that people taking bupropion are more likely to discontinue treatment compared with placebo. However, there is no clear evidence to suggest whether people taking bupropion experience more or fewer SAEs than those taking placebo (moderate certainty). Nortriptyline also appears to have a beneficial effect on smoking quit rates relative to placebo. Evidence suggests that bupropion may be as successful as NRT and nortriptyline in helping people to quit smoking, but that it is less effective than varenicline. There is insufficient evidence to determine whether the other antidepressants tested, such as SSRIs, aid smoking cessation, and when looking at safety and tolerance outcomes, in most cases, paucity of data made it difficult to draw conclusions. Due to the high-certainty evidence, further studies investigating the efficacy of bupropion versus placebo are unlikely to change our interpretation of the effect, providing no clear justification for pursuing bupropion for smoking cessation over front-line smoking cessation aids already available. However, it is important that where studies of antidepressants for smoking cessation are carried out they measure and report safety and tolerability clearly.

Abstract
Smoking causes various diseases and is a major public health threat worldwide.
Therefore, promoting smoking cessation is the most important intervention
contributing to maintaining the health of smokers and nonsmokers and saving
enormous financial expense. We reviewed existing and emerging smoking-cessation
pharmacotherapies from the Cochrane Database of Systemic Reviews, PubMed, Ovid,
and ClinicalTrials.gov databases. A literature review revealed that bupropion
may be appropriate for patients interested in reducing smoking who dislike, or
who have failed, nicotine-replacement therapy (NRT). Additionally, varenicline
and NRT are efficacious first-line smoking cessation treatments and should be
given to all individuals unless contraindicated. The reviews of this paper are available via the supplementary material
section.

Abstract
Background Smokers with comorbid anxio-depressive disorders are more prone to progress to a more severe level of dependence and to experience more severe nicotine withdrawal symptoms than smokers without anxio-depressive disorders. Aim of the study To determine the relationship between tobacco dependence and anxio-depressive disorders as well as assessing their impact on the withdrawal. Methods We conducted a cross-sectional study among attendees of the smoking cessation clinic of Sahloul University Hospital, Sousse, Tunisia, from December 2009 to May 2015. The monitoring of the attendees was performed through retrieving the records until May 2016 in order to verify their smoking cessation status at 1 year. Results Overall, 534 smokers were included. We identified 315 smokers (59%) presenting an anxio-depressive disorder. Based on the HAD scale, we found 231 patients (43.4%) with anxiety disorders, 200 (37.6%) patients with depressive disorders, and 116 (21.8%) patients with anxio-depressive disorder. In multivariate analysis, only a high number of consultation was associated with a better rate of tobacco cessation at 6 months. However, no factor was found linked to the relapse at 1 year. Conclusion According to our results, only a high number of consultation was revealed as an independent factor of withdrawal for anxio-depressed smokers. It is necessary to simultaneously use the nicotinic substitutions and anxio-depressive treatment to ensure the tobacco cessation.

Abstract
BACKGROUND Tobacco cessation methods employed by patients with head and neck cancer (HNSCC) are previously unstudied and have the potential to inform choice of cessation method and necessary abstinence support. METHODS A total of 130 current smokers with HNSCC were queried regarding prior unsuccessful tobacco cessation techniques, product used (cold turkey, varenicline, and nicotine patch/gum), and maximum time abstained from smoking. RESULTS One hundred six smokers retrospectively reported using one of the four main quit methods. Unassisted cessation ("cold turkey") was the most commonly used method (P < .001). A multiple ordinal logistic general estimating equation analysis revealed that cold turkey had increased odds [5.2 (95% confidence interval [CI]: 2.2, 11.8) and 4.3 (95% CI: 1.5, 12.9)] of achieving a longer quit duration than the nicotine patch or varenicline, respectively. CONCLUSIONS Among smokers developing HNSCC, previous cessation attempts were most commonly unassisted. This method was associated with longest abstinence periods. These data suggest insufficient support and education regarding behavioral and pharmacologic cessation therapies.

Varenicline and Bupropion for Long-Term Smoking Cessation (the MATCH Study): Protocol for a Real-World, Pragmatic, Randomized Controlled Trial. JMIR Res Protoc 2018; 7:e10826. [PMID: 30341043 PMCID: PMC6231835 DOI: 10.2196/10826] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 06/01/2018] [Accepted: 06/29/2018] [Indexed: 11/13/2022] Open
Abstract
Background Varenicline and bupropion are efficacious, prescription-only pharmacotherapies for smoking cessation; however, their real-world impact is limited by prescriber knowledge, affordability, and accessibility. Objective The primary objective of the MATCH (Medication Aids for Tobacco Cessation Health) study was to evaluate the real-world, long-term effectiveness of mailed bupropion and varenicline in a sample of interested smokers with the utilization of Web-based recruitment and follow-up. In addition, the study aims to investigate the genotypic and phenotypic predictors of cessation. Methods This is a two-group, parallel block, randomized (1:1) open-label clinical trial. This study will be conducted online with the baseline enrollment through the study’s website and follow-up by emails. In addition, medication prescriptions will be filled by the study contract pharmacy and couriered to participants. Individuals who smoke ≥10 cigarettes per day and intend to quit within the next 30 days will be recruited through Public Health Units and Tobacco Control Area Networks throughout Ontario by word-of-mouth and the internet. Eligible participants will receive an email with a prescription for 12-week assigned medication and a letter to take to their physician. The recruitment and randomization will continue until 500 participants per arm have received medication. All participants will receive weekly motivational emails during the treatment phase. The primary outcome measure is the smoking status after 6 months, biochemically confirmed by mailed-in salivary cotinine. Follow-ups will be conducted through emails after 4, 8, 12, 26, and 52 weeks of starting the treatment to assess the smoking prevalence and continuous smoking abstinence. In addition, mailed-in saliva samples will be used for genetic and nicotine metabolism analyses. Furthermore, personality characteristics will be assessed using the Big Five Aspect Scales. Results The project was funded in 2014 and enrollment was completed in January 2017. Data analysis is currently underway. Conclusions To the best of our knowledge, this is the first randomized controlled trial to mass distribute prescription medications for smoking cessation. We expect this method to be logistically feasible and cost effective with quit outcomes that are comparable to published clinical trials.

Abstract
INTRODUCTION Tobacco use remains the leading cause of preventable death in the United States. There are efficacious behavioral and pharmacological options for smoking cessation including three FDA approved therapies - nicotine replacement therapy, varenicline and bupropion. Nevertheless, uptake of smoking cessation treatments continues to be poor and there is a need for novel smoking cessation treatments. Areas covered: This article reviews the biobehavioral basis of nicotine addiction, its implications for smoking cessation treatments, the various neurotransmitter systems involved in nicotine addictive effects, and their potential therapeutic value. Included are discussions around the role of genetic factors in predicting response to pharmacotherapy and what we know about appropriate application of pharmacotherapy and behavioral interventions for tobacco use disorder. The evidence for harm reduction measures in individuals who are not willing or able to quit smoking is also reviewed. Expert commentary: Many neurotransmitter system targets have been investigated as a result of our understanding of the underlying neurobiology of tobacco use disorder, and there remain important targets that have yet to be fully explored. rTMS or combination therapies are proposed as possible novel strategies to improve smoking cessation.

Abstract
Despite significant population level declines, smoking during pregnancy remains a major public health issue in the United States (US). Approximately 360,000-500,000 smoke-exposed infants are born yearly, and prenatal smoking remains a leading modifiable cause of poor birth outcomes (e.g. birth < 37 gestational weeks, low birth weight, perinatal mortality). Women who smoke during pregnancy are more likely to be younger and from disadvantaged socioeconomic and racial and ethnic groups, with some US geographic regions reporting increased prenatal smoking rates since 2000. Such disparities in maternal prenatal smoking suggests some pregnant women face unique barriers to cessation. This paper reviews the current state and future direction of smoking cessation in pregnancy in the US. We briefly discuss the etiology of smoking addiction among women, the pathophysiology and effects of tobacco smoke exposure on pregnant women and their offspring, and the emerging issue of electronic nicotine delivery systems. Current population-based and individual smoking cessation interventions are reviewed in the context of pregnancy and barriers to cessation among US women. Finally, we consider interventions that are on the horizon and areas in need of further investigation.

Abstract
BACKGROUND Although nicotine alters serotonergic neurochemistry, clinical trials of serotonergic medications for smoking cessation have provided mixed results. Understanding the role of serotonergic dysfunction in tobacco use disorder may advance development of novel pharmacotherapies. METHODS Functional magnetic resonance imaging was used to measure resting-state functional connectivity of the raphe nuclei as an indicator of serotonergic function. Connectivity of the dorsal and median raphe nuclei was compared between 18 young smokers (briefly abstinent, ~40 minutes post-smoking) and 19 young nonsmokers (16-21 years old); connectivity was also examined in a separate sample of overnight-abstinent smokers (18-25 years old), before and after smoking the first cigarette of the day. Relationships between connectivity of the raphe nuclei with psychological withdrawal and craving were tested in smokers. RESULTS Connectivity of the median raphe nucleus with the right hippocampal complex was weaker in smokers than in nonsmokers and was negatively correlated with psychological withdrawal in smokers. In overnight-abstinent smokers, smoking increased connectivity of the median raphe nucleus with the right hippocampal complex, and the increase was positively correlated with the decrease in psychological withdrawal. CONCLUSIONS Relief of withdrawal due to smoking is potentially linked to the serotonergic pathway that includes the median raphe nucleus and hippocampal complex. These results suggest that serotonergic medications may be especially beneficial for smokers who endorse strong psychological withdrawal during abstinence from smoking.

Cost-effectiveness of alternative smoking cessation scenarios in Spain: results from the EQUIPTMOD. Addiction 2018; 113 Suppl 1:65-75. [PMID: 29532966 PMCID: PMC6032934 DOI: 10.1111/add.14090] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2017] [Revised: 08/07/2017] [Accepted: 11/02/2017] [Indexed: 12/02/2022]
Abstract
AIMS To assess the cost-effectiveness of alternative smoking cessation scenarios from the perspective of the Spanish National Health Service (NHS). DESIGN We used the European study on Quantifying Utility of Investment in Protection from Tobacco model (EQUIPTMOD), a Markov-based state transition economic model, to estimate the return on investment (ROI) of: (a) the current provision of smoking cessation services (brief physician advice and printed self-helped material + smoking ban and tobacco duty at current levels); and (b) four alternative scenarios to complement the current provision: coverage of proactive telephone calls; nicotine replacement therapy (mono and combo) [prescription nicotine replacement therapy (Rx NRT)]; varenicline (standard duration); or bupropion. A rate of 3% was used to discount life-time costs and benefits. SETTING Spain. PARTICIPANTS Adult smoking population (16+ years). MEASUREMENTS Health-care costs associated with treatment of smoking attributable diseases (lung cancer, coronary heart disease, chronic obstructive pulmonary infection and stroke); intervention costs; quality-adjusted life years (QALYs). Costs and outcomes were summarized using various ROI estimates. FINDINGS The cost of implementing the current provision of smoking cessation services is approximately €61 million in the current year. This translates to 18 quitters per 1000 smokers and a life-time benefit-cost ratio of 5, compared with no such provision. All alternative scenarios were dominant (cost-saving: less expensive to run and generated more QALYs) from the life-time perspective, compared with the current provision. The life-time benefit-cost ratios were: 1.87 (proactive telephone calls); 1.17 (Rx NRT); 2.40 (varenicline-standard duration); and bupropion (2.18). The results remained robust in the sensitivity analysis. CONCLUSIONS According to the EQUIPTMOD modelling tool it would be cost-effective for the Spanish authorities to expand the reach of existing GP brief interventions for smoking cessation, provide pro-active telephone support, and reimburse smoking cessation medication to smokers trying to stop. Such policies would more than pay for themselves in the long run.

Abstract
AIMS To evaluate potential health and economic returns from implementing smoking cessation interventions in Hungary. METHODS The EQUIPTMOD, a Markov-based economic model, was used to assess the cost-effectiveness of three implementation scenarios: (a) introducing a social marketing campaign; (b) doubling the reach of existing group-based behavioural support therapies and proactive telephone support; and (c) a combination of the two scenarios. All three scenarios were compared with current practice. The scenarios were chosen as feasible options available for Hungary based on the outcome of interviews with local stakeholders. Life-time costs and quality-adjusted life years (QALYs) were calculated from a health-care perspective. The analyses used various return on investment (ROI) estimates, including incremental cost-effectiveness ratios (ICERs), to compare the scenarios. Probabilistic sensitivity analyses assessed the extent to which the estimated mean ICERs were sensitive to the model input values. RESULTS Introducing a social marketing campaign resulted in an increase of 0.3014 additional quitters per 1 000 smokers, translating to health-care cost-savings of €0.6495 per smoker compared with current practice. When the value of QALY gains was considered, cost-savings increased to €14.1598 per smoker. Doubling the reach of existing group-based behavioural support therapies and proactive telephone support resulted in health-care savings of €0.2539 per smoker (€3.9620 with the value of QALY gains), compared with current practice. The respective figures for the combined scenario were €0.8960 and €18.0062. Results were sensitive to model input values. CONCLUSIONS According to the EQUIPTMOD modelling tool, it would be cost-effective for the Hungarian authorities introduce a social marketing campaign and double the reach of existing group-based behavioural support therapies and proactive telephone support. Such policies would more than pay for themselves in the long term.

Abstract
BACKGROUND AND AIMS Despite the availability of several efficacious smoking cessation treatments, fewer than 25% of smokers who quit remain abstinent 1 year post-treatment. This study aimed to determine if varenicline and bupropion combination treatment would result in higher abstinence rates than varenicline alone. DESIGN A double-blind, randomized, parallel-group smoking cessation clinical trial in which participants were exposed to 12 weeks of treatment and followed for 12 months. SETTING Hospital-based out-patient clinic in Texas, USA specializing in cancer prevention. PARTICIPANTS A total of 385 community smokers (58.44% male) who smoked 1 pack of cigarettes/day [mean = 19.66 cigarettes/day, standard deviation (SD) = 9.45]; had average carbon monoxide (CO) of 26.43 parts per million (SD = 13.74); and were moderately dependent (Fagerström Test for Cigarette Dependence = 4.79; SD = 2.07). INTERVENTIONS AND COMPARATOR Smokers were randomized in a 3 : 1 (active: Placebo) ratio to 12 weeks of treatment as follows: placebo (n = 56), varenicline (Var; n = 166), and varenicline + bupropion (Combo; n = 163). MEASUREMENTS A priori primary outcome: prolonged abstinence at 12 months. SECONDARY OUTCOMES 7-day point prevalence abstinence and continuous abstinence; all abstinence measures at end of treatment and 6-month follow-ups. FINDINGS Intention-to-treat analysis: the Combo group (n = 163) failed to demonstrate superiority to the Var group (n = 166) for prolonged abstinence at 12 months [odds ratio (OR) = 0.91, 95% confidence interval (CI) = 0.50-1.64], supported by Bayes factor = 0.06. Both the Var (OR = 6.66, 95% CI = 1.61-59.27) and Combo groups (OR = 6.06, 95% CI = 1.45-54.09) demonstrated superiority to the Placebo group (n = 56; score = 8.38, P < 0.016). CONCLUSIONS The addition of bupropion to varenicline treatment does not appear to increase smoking abstinence rates above that of varenicline alone. The findings support previous research showing a consistently favorable effect of both varenicline and the combination of varenicline and bupropion on smoking cessation compared with placebo.

Abstract
AIMS To study the effectiveness of intensive counselling by a practice nurse (PN) versus brief advice by a general practitioner (GP), each combined with pharmacotherapy, for 6 months' tobacco abstinence (primary outcome). Secondary outcomes included 12-month abstinence, medication adherence and incremental costs per life-year gained. DESIGN A multi-site (n = 10), two-group, parallel, pragmatic randomized controlled trial. SETTING A network of primary health-care centres in the Netherlands. PARTICIPANTS A total of 295 adult daily smokers (mean age = 48 years; mean cigarettes/day = 19). INTERVENTION AND COMPARATOR Patients were randomized to receive individual counselling by a practice nurse (PN) (n = 149) or brief advice by a general practitioner (GP) (146). All patients received 12 weeks of open-label varenicline. MEASUREMENTS The primary outcome was prolonged biochemically validated abstinence from weeks 9 to 26 after treatment initiation. Secondary outcomes included abstinence from weeks 9 to 52, good dosing adherence (> 80% days taken) and incremental costs per life-year gained. FINDINGS Abstinence rates in the PN versus GP groups were 32.2% (n = 48) versus 39.0% [n = 57; odds ratio (OR) = 0.71; 95% confidence interval (CI) = 0.44-1.16] from weeks 9 to 26 and 25.5% (n = 38) versus 28.8% (n = 42; OR = 0.84, 95% CI = 0.50-1.43) from weeks 9 to 52, respectively. Values of the Bayes factor indicated that the PN and GP were equally effective. Good dosing adherence was significantly lower in the PN (45.5%, n = 56/123) than in the GP group (62.0%, n = 75/121; OR = 0.45, 95% CI = 0.26-0.77), and the incremental costs per life-year gained were -€416.10. CONCLUSIONS Among people seeking help to stop smoking from their general practice, one-off brief advice from a general practitioner appears to be as effective as several sessions of behavioural support from a practice nurse when smoking cessation medication is provided.

Abstract
Cigarette smoking-a crucial modifiable risk factor for organ system diseases and cancer-remains prevalent in the United States and globally. In this literature review, we aim to summarize the epidemiology of cigarette smoking and tobacco use in the United States, pharmacology of nicotine-the active constituent of tobacco, and health consequence of cigarette smoking. This article also reviews behavioral and pharmacologic interventions for cigarette smokers and provides cost estimates for approved pharmacologic interventions in the United States. A literature search was conducted on Google Scholar, EBSCOhost, ClinicalKey, and PubMed databases using the following headings in combination or separately: cigarette smoking, tobacco smoking, epidemiology in the United States, health consequences of cigarette smoking, pharmacologic therapy for cigarette smoking, and non-pharmacologic therapy for cigarette smoking. This review found that efficacious non-pharmacologic interventions and pharmacologic therapy are available for cessation of cigarette smoking. Given the availability of efficacious interventions for cigarette smoking cessation, concerted efforts should be made by healthcare providers and public health professionals to promote smoking cessation as a valuable approach for reducing non-smokers' exposure to environmental tobacco smoke.

Abstract
Approximately 20% of pregnant women smoke despite intentions to quit. Smoking cessation drugs, such as nicotine replacement therapy (NRT) and bupropion, are recommended treatments. Adverse cardiovascular outcomes in offspring have raised concerns about NRT's safety during pregnancy. However, the effect of bupropion is unknown. Using a rat model, we determined whether NRT and bupropion interventions during pregnancy are safer than continued smoking on offspring's cardiovascular function. Male offspring of controls and dams exposed to cigarette smoke (1.6 packs/day, inhalation), nicotine (2 mg/kg/d subcutaneously), and bupropion (13 mg/kg twice daily orally) were assessed for fetoplacental weight, cardiac function, blood pressure, and vascular reactivity. Fetoplacental weights were decreased and spontaneous beating and intracellular calcium in neonatal cardiomyocytes were increased in smoking, nicotine, and bupropion offspring; however, these effects were more accentuated in smoking followed by nicotine and bupropion offspring. Increased heart rate and decreased cardiac output, stroke volume, and left ventricular percent posterior wall thickening were observed in smoking, nicotine, and bupropion offspring. The left ventricular mass was reduced in smoking and nicotine but not in bupropion offspring. Blood pressure was higher with decreased endothelium-dependent relaxation and exaggerated vascular contraction to angiotensin II in smoking and nicotine offspring, with more pronounced dysfunctions in smoking than nicotine offspring. Maternal bupropion did not impact offspring's blood pressure, endothelium-dependent relaxation, and vascular contraction. In conclusion, maternal nicotine intervention adversely affects offspring's cardiovascular outcomes, albeit less severely than continued smoking. However, bupropion causes cardiac derangement in offspring but does not adversely affect blood pressure and vascular function.

[PMID: 27812523 PMCID: PMC5071375 DOI: 10.3389/fpubh.2016.00228] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2016] [Accepted: 09/29/2016] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The Indigenous Tobacco Control Initiative and Tackling Indigenous Smoking Measure were both announced by the Australian Government at a time when its rhetoric around the importance of evidence-based policy making was strong. This article will (1) examine how the Rudd Government used evidence in Indigenous tobacco control policy making and (2) explore the facilitators of and barriers to the use of evidence. METHODS Data were collected through (1) a review of primary documents largely obtained under the Freedom of Information Act 1982 (Commonwealth of Australia) and (2) interviews with senior politicians, senior bureaucrats, government advisors, Indigenous health advocates, and academics. Through the Freedom of Information Act process, 24 previously undisclosed government documents relevant to the making of Indigenous tobacco control policies were identified. Interviewees (n = 31, response rate 62%) were identified through both purposive and snowball recruitment strategies. The Framework Analysis method was used to analyze documentary and interview data. RESULTS Government policy design was heavily influenced by the recommendations presented in government authored/commissioned literature reviews. Resulting policies were led by equivocal evidence for improved tobacco control outcomes among Indigenous Australians. Many of the cited studies had methodological limitations. In the absence of high-quality evidence, some policy makers supported policy recommendations that were perceived to be popular among the Indigenous community. Other policy makers recognized that there were barriers to accumulating rigorous, generalizable evidence; in the absence of such evidence, the policy makers considered that the "need for action" could be combined with the "need for research" by introducing innovative strategies and evaluating them. DISCUSSION Despite the absence of high-quality evidence, the formulation and adoption of Indigenous tobacco policy was neither irrational nor reckless. The decision to adopt an innovate and evaluate strategy was justifiable given (a) the potential for the gap between Indigenous and non-Indigenous health outcomes to worsen in the absence of an imminent policy response; (b) the existence of circumstances, which made it difficult to obtain high-quality evidence to guide policy; and (c) the need for policy solutions to reflect community preferences, given sociohistorical sensitivities.

Understanding implementation and feasibility of tobacco cessation in routine primary care in Nepal: a mixed methods study. Implement Sci 2016; 11:104.

Abstract
Background By 2030, 80 % of the annual 8.3 million deaths attributable to tobacco will be in low-income countries (LICs). Yet, services to support people to quit tobacco are not part of routine primary care in LICs. This study explored the challenges to implementing a behavioural support (BS) intervention to promote tobacco cessation within primary care in Nepal. Methods The study used qualitative and quantitative methods within an action research approach in three primary health care centres (PHCCs) in two districts of Nepal. Before implementation, 21 patient interviews and two focus groups with health workers informed intervention design. Over a 6-month period, two researchers facilitated action research meetings with staff and observed implementation, recording the process and their reflections in diaries. Patients were followed up 3 months after BS to determine tobacco use (verified biochemically) and gain feedback on the intervention. A further five interviews with managers provided reflections on the process. The qualitative analysis used Normalisation Process Theory (NPT) to understand implementation. Results Only 2 % of out-patient appointments identified the patient as a smoker. Qualitative findings highlight patients’ unwillingness to admit their smoking status and limited motivation among health workers to offer the intervention. Patient-centred skills needed for BS were new to staff, who found them challenging particularly with low-literacy patients (skill set workability). Heath workers saw cessation advice and BS as an addition to their existing workload (relational integration). While there was strong policy buy-in, operationalising this through reporting and supervision was limited (contextual integration). Of the 44 patients receiving the intervention, 27 were successfully followed up after 3 months; 37 % of these had quit (verified biochemically). Conclusions Traditionally, primary health care in LICs has focused on acute care; with increasing recognition of the need for lifestyle change, health workers must develop new skills and relationships with patients. Appropriate and regular recording, reporting, supervision and clear leadership are needed if health workers are to take responsibility for smoking cessation. The consistent implementation of these health system activities is a requirement if cessation services are to be normalised within routine primary care.

Abstract
BACKGROUND Smoking during pregnancy is the main preventable cause of poor birth outcomes. Improved methods are needed to help women to stop smoking during pregnancy. Pregnancy provides a compelling rationale for physical activity (PA) interventions as cessation medication is contraindicated or ineffective, and an effective PA intervention could be highly cost-effective. OBJECTIVE To examine the effectiveness and cost-effectiveness of a PA intervention plus standard behavioural support for smoking cessation relative to behavioural support alone for achieving smoking cessation at the end of pregnancy. DESIGN Multicentre, two-group, pragmatic randomised controlled trial and economic evaluation with follow-up at the end of pregnancy and 6 months postnatally. Randomisation was stratified by centre and a computer-generated sequence was used to allocate participants using a 1 : 1 ratio. SETTING 13 hospitals offering antenatal care in the UK. PARTICIPANTS Women between 10 and 24 weeks' gestation smoking five or more cigarettes a day before pregnancy and one or more during pregnancy. INTERVENTIONS Participants were randomised to behavioural support for smoking cessation (control) or behavioural support plus a PA intervention consisting of supervised treadmill exercise plus PA consultations. Neither participants nor researchers were blinded to treatment allocation. MAIN OUTCOME MEASURES The primary outcome was self-reported, continuous smoking abstinence between a quit date and end of pregnancy, validated by expired carbon monoxide and/or salivary cotinine. Secondary outcomes were maternal weight, depression, birth outcomes, withdrawal symptoms and urges to smoke. The economic evaluation investigated the costs of the PA intervention compared with the control intervention. RESULTS In total, 789 women were randomised (n = 394 PA, n = 395 control). Four were excluded post randomisation (two had been enrolled twice in sequential pregnancies and two were ineligible and randomised erroneously). The intention-to-treat analysis comprised 785 participants (n = 392 PA, n = 393 control). There was no significant difference in the rate of abstinence at the end of pregnancy between the PA group (7.7%) and the control group (6.4%) [odds ratio for PA group abstinence 1.21, 95% confidence interval (CI) 0.70 to 2.10]. For the PA group compared with the control group, there was a 33% (95% CI 14% to 56%), 28% (95% CI 7% to 52%) and 36% (95% CI 12% to 65%) significantly greater increase in self-reported minutes of moderate- and vigorous-intensity PA from baseline to 1 week, 4 weeks and 6 weeks respectively. Accelerometer data showed that there was no significant difference in PA levels between the groups. There were no significant differences between the groups for change in maternal weight, depression, withdrawal symptoms or urges to smoke. Adverse events and birth outcomes were similar between the groups except for there being significantly more caesarean births in the control group than in the PA group (28.7% vs. 21.3%; p < 0.023). The PA intervention was less costly than the control intervention by £35 per participant. This was mainly attributable to increased health-care usage in the control group. However, there was considerable statistical uncertainty around this estimate. CONCLUSIONS During pregnancy, offering an intervention combining supervised exercise and PA counselling does not add to the effectiveness of behavioural support for smoking cessation. Only 10% of participants had PA levels accessed by accelerometer and it is, therefore, unclear whether or not the lack of an effect on the primary outcome is the result of insufficient increases in PA. Research is needed to identify the smoking populations most suitable for PA interventions and methods for increasing PA adherence. TRIAL REGISTRATION Current Controlled Trials ISRCTN48600346.

Abstract
Motivational interventions help people with mental illness try to quit smoking, but few studies have evaluated factors associated with this groups' cessation with community treatment. We examined predictors of abstinence after a brief motivational intervention among smokers with severe mental illness. Education, stage of change post intervention, and use of cessation treatment predicted any 1-week period of self-reported abstinence over 6 months (29%). Cessation treatment mediated the relationship between stage of change and abstinence. Because treatment was the key modifiable predictor of abstinence, future research should establish strategies that improve motivation for, access to, and retention in cessation treatment.

Abstract
Tobacco use is the largest cause of preventable mortality in the western world. Even after treatment, relapse rates for tobacco are high, and more effective pharmacological treatments are needed. Progesterone (PRO), a female hormone used in contraceptives, reduces stimulant use but its effects on tobacco addiction are unknown. Varenicline (VAR) is a commonly used medication that reduces tobacco use. The present study examined sex differences in the individual vs. combined effects of PRO and VAR on reinstatement of nicotine-seeking behavior in a rat model of relapse. Adult female and male Wistar rats self-administered nicotine (NIC, 0.03mg/kg/infusion) for 14days followed by 21days of extinction when no cues or drug were present. Rats were then divided into 4 treatment groups: control (VEH+SAL), PRO alone (PRO+SAL), VAR alone (VEH+VAR) and the combination (PRO+VAR). Reinstatement of nicotine-seeking behavior induced by priming injections of NIC or caffeine (CAF), presentation of cues (CUES), and the combination of drugs and cues (e.g. NIC+CUES, CAF+CUES) were tested after extinction. Male and female rats did not differ in self-administration of nicotine or extinction responding, and both showed elevated levels of responding to the CAF+CUES condition. However, males, but not females, reinstated active lever-pressing to the NIC+CUES condition, and that was attenuated by both VAR and VAR+PRO treatment. Thus, males were more sensitive to NIC+CUE-induced reinstatement than females, and VAR alone and VAR combined with PRO effectively reduced nicotine relapse.

Abstract
INTRODUCTION The nicotine-metabolite ratio (NMR) predicts treatment response and is related to treatment side effect severity. Sleep disturbance may be one important side effect, but understanding sleep disturbance effects on smoking cessation is complicated by the fact that nicotine withdrawal also produces sleep disturbance. AIMS To evaluate the effects of withdrawal and treatment side effects on sleep disturbance. METHODS This is a secondary analysis of data from a clinical trial (Lerman et al., 2015) of 1,136 smokers randomised to placebo (n = 363), transdermal nicotine (TN; n = 381), or varenicline (n = 392) and stratified based on NMR (559 slow metabolisers; 577 normal metabolisers). Sleep disturbance was assessed at baseline and at 1-week following the target quit date (TQD). We also examined whether sleep disturbance predicted 7-day point-prevalence abstinence at end-of-treatment (EOT). RESULTS The varenicline and TN groups exhibited greater increases in sleep disturbance (vs. placebo; treatment × time interaction; p = 0.005), particularly among those who quit smoking at 1-week post-TQD. There was a main effect of NMR (p = 0.04), but no interactions with treatment. TN and varenicline attenuated withdrawal symptoms unrelated to sleep (vs. placebo). Greater baseline sleep disturbance predicted relapse at EOT (p = 0.004). CONCLUSIONS Existing treatments may not mitigate withdrawal-related sleep disturbance and adjunctive treatments that target sleep disturbance may improve abstinence rates.

Abstract
BACKGROUND There is a high prevalence of smoking among people who experience severe mental ill health (SMI). Helping people with disorders such as bipolar illness and schizophrenia to quit smoking would help improve their health, increase longevity and also reduce health inequalities. Around half of people with SMI who smoke express an interest in cutting down or quitting smoking. There is limited evidence that smoking cessation can be achieved for people with SMI. Those with SMI rarely access routine NHS smoking cessation services. This suggests the need to develop and evaluate a behavioural support and medication package tailored to the needs of people with SMI. OBJECTIVE The objective in this project was to conduct a pilot trial to establish acceptability of the intervention and to ensure the feasibility of recruitment, randomisation and follow-up. We also sought preliminary estimates of effect size in order to design a fully powered trial of clinical effectiveness and cost-effectiveness. The pilot should inform a fully powered trial to compare the clinical effectiveness and cost-effectiveness of a bespoke smoking cessation (BSC) intervention with usual general practitioner (GP) care for people with SMI. DESIGN A pilot pragmatic two-arm individually randomised controlled trial (RCT). Simple randomisation was used following a computer-generated random number sequence. Participants and practitioners were not blinded to allocation. SETTING Primary care and secondary care mental health services in England. PARTICIPANTS Smokers aged > 18 years with a severe mental illness who would like to cut down or quit smoking. INTERVENTIONS A BSC intervention delivered by mental health specialists trained to deliver evidence-supported smoking cessation interventions compared with usual GP care. MAIN OUTCOME MEASURES The primary outcome was carbon monoxide-verified smoking cessation at 12 months. Smoking-related secondary outcomes were reduction of number of cigarettes smoked, Fagerstrom test of nicotine dependence and motivation to quit (MTQ). Other secondary outcomes were Patient Health Questionnaire-9 items and Short Form Questionnaire-12 items to assess whether there were improvements or deterioration in mental health and quality of life. We also measured body mass index to assess whether or not smoking cessation was associated with weight gain. These were measured at 1, 6 and 12 months post randomisation. RESULTS The trial recruited 97 people aged 19-73 years who smoked between 5 and 60 cigarettes per day (mean 25 cigarettes). Participants were recruited from four mental health trusts and 45 GP surgeries. Forty-six people were randomised to the BSC intervention and 51 people were randomised to usual GP care. The odds of quitting at 12 months was higher in the BSC intervention (36% vs. 23%) but did not reach statistical significance (odds ratio 2.9; 95% confidence interval 0.8% to 10.5%). At 3 and 6 months there was no evidence of difference in self-reported smoking cessation. There was a non-significant reduction in the number of cigarettes smoked and nicotine dependence. MTQ and number of quit attempts all increased in the BSC group compared with usual care. There was no difference in terms of quality of life at any time point, but there was evidence of an increase in depression scores at 12 months for the BSC group. There were no serious adverse events thought likely to be related to the trial interventions. The pilot economic analysis demonstrated that it was feasible to carry out a full economic analysis. CONCLUSIONS It was possible to recruit people with SMI from primary and secondary care to a trial of a smoking cessation intervention based around behavioural support and medication. The overall direction of effect was a positive trend in relation to biochemically verified smoking cessation and it was feasible to obtain follow-up in a substantial proportion of participants. A definitive trial of a bespoke cessation intervention has been prioritised by the National Institute for Health Research (NIHR) and the SCIMITAR pilot trial forms a template for a fully powered RCT to examine clinical effectiveness and cost-effectiveness.

[PMID: 25589680 PMCID: PMC4612343 DOI: 10.1093/ntr/ntu347] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2014] [Accepted: 12/24/2014] [Indexed: 12/26/2022]
Abstract
INTRODUCTION Understanding the mechanisms by which bupropion promotes smoking cessation may lead to more effective treatment. To the extent that reduced smoking reinforcement is one such mechanism, a longer duration of pre quit bupropion treatment should promote extinction of smoking behavior. We evaluated whether 4 weeks of pre quit bupropion (extended run-in) results in greater pre quit reductions in smoking rate and cotinine and, secondarily, greater short-term abstinence, than standard 1 week of pre quit bupropion (standard run-in). METHODS Adult smokers (n = 95; 48 females) were randomized to a standard run-in group (n = 48; 3-week placebo, then 1-week bupropion pre quit) or an extended run-in group (4-week pre quit bupropion; n = 47). Both groups received group behavioral counseling and 7 weeks of post quit bupropion. Smoking rate (and craving, withdrawal, and subjective effects) was collected daily during the pre quit period; biochemical data (cotinine and carbon monoxide) were collected at study visits. RESULTS During the pre quit period, the extended run-in group exhibited a greater decrease in smoking rate, compared to the standard run-in group, interaction p = .03. Cigarette craving and salivary cotinine followed a similar pattern, though the latter was evident only among women. Biochemically verified 4-week continuous abstinence rates were higher in the extended run-in group (53%) than the standard run-in group (31%), p = .033. CONCLUSIONS The extended use of bupropion prior to a quit attempt reduces smoking behavior during the pre quit period and improved short-term abstinence rates. The data are consistent with an extinction-of-reinforcement model and support further investigation of extended run-in bupropion therapy for smoking cessation.

Abstract
Patient visits are an important opportunity for general practitioners (GPs) to discuss the risks of smoking and cessation strategies. In Australia, the guidelines on cessation published by the Royal Australian College of General Practitioners (the Guidelines) represent a key resource for GPs in this regard. The predominant message of the Guidelines is that pharmacotherapy should be recommended as first-line therapy for smokers expressing an interest in quitting. This, however, ignores established evidence about the success of unassisted quitting. Our analysis of the Guidelines identifies a number of potential conflicts of interest which may have affected the advice provided. These include extensive funding by the pharmaceutical industry of sources cited to support the recommendations, and relations between members of the Guidelines Content Advisory Group and the pharmaceutical industry. Recommendations issued by professional bodies have enormous potential impact upon public health and there is a need for the highest levels of scrutiny and transparency in their development. Information about research cited in guidelines should include funding sources, and developers should be free of obvious conflicts of interest. Smoking remains the leading preventable cause of global mortality. Concerns related to pharmaceutical industry funding of research, scientific integrity and recommendations on smoking cessation by medical advisory groups clearly have implications beyond Australia.

Abstract
UNLABELLED There are different modalities for management of Nicotine dependence, but it is still inconclusive which is the best modality for the treatment of Nicotine dependence syndrome (NDS). In this background the present study was carried out to assess the efficacy and to compare different modalities for the treatment of NDS. METHODS Patients diagnosed as NDS as per ICD-10 were taken up for study. These patients were administered proforma to elicit sociodemographic details, Fagerstrom test for Nicotine Dependence, Questionnaire of Smoking Urges-Brief and breath analysis was done using carbon monoxide meter. Assessment was done at base line and at weekly follow-ups for 12 weeks. Patients were divided into six groups randomly. Group A received BUP at a dose of 150mg/day for 3 days; subsequently increased to 300mg/day, Group B: for initial 6 weeks Nicotine gum of 4mg every 1-2 hourly was used and next 6 weeks every 2-4 hourly was used, Group C: BI, Group D: BI+BUP, Group E: BI+NRT, Group F received BUP+NRT+BI. RESULTS The quit rates at end of the study were BUP-30%, NRT-26.66%, BI-23.33%, BI+BUP-43.33%, BI+NRT-33.33%, and BI+BUP+NRT-50%. BI+BUP+NRT had 2-3 times more quit rates than the individual modality treatment group. CONCLUSION There was no statistically significant difference between the study groups, but there was clinical difference in quit rates. Among the groups BI+BUP+NRT had higher quit rates compared to other groups. Combination modalities yield better quit rates than individual modalities.

Abstract
Background Varenicline is an effective pharmacotherapy to aid smoking cessation. However, its use is limited by continuing concerns about possible associated risks of serious adverse cardiovascular and neuropsychiatric events. The aim of this study was to investigate whether use of varenicline is associated with such events. Methods In this retrospective cohort study, we used data from patients included in the validated QResearch database, which holds data from 753 National Health Service general practices across England. We identified patients aged 18–100 years (registered for longer than 12 months before data extraction) who received a prescription of nicotine replacement treatment (NRT; reference group), bupropion, or varenicline. We excluded patients if they had used one of the drugs during the 12 months before the start date of the study, had received a prescription of a combination of these drugs during the follow-up period, or were temporary residents. We followed patients up for 6 months to compare incident cardiovascular (ischaemic heart disease, cerebral infarction, heart failure, peripheral vascular disease, and cardiac arrhythmia) and neuropsychiatric (depression and self-harm) events using Cox proportional hazards models, adjusted for potential confounders (primary outcomes). Findings We identified 164 766 patients who received a prescription (106 759 for nicotine replacement treatment; 6557 for bupropion; 51 450 for varenicline) between Jan 1, 2007, and June 30, 2012. Neither bupropion nor varenicline showed an increased risk of any cardiovascular or neuropsychiatric event compared with NRT (all hazard ratios [HRs] less than 1. Varenicline was associated with a significantly reduced risk of ischaemic heart disease (HR 0·80 [95%CI 0·72–0·87]), cerebral infarction (0·62 [0·52–0·73]), heart failure (0·61 [0·45–0·83]), arrhythmia (0·73 [0·60–0·88]), depression (0·66 [0·63–0·69]), and self-harm (0·56 [0·46–0·68]). Interpretation Varenicline does not seem to be associated with an increased risk of documented cardiovascular events, depression, or self-harm when compared with NRT. Adverse events that do not come to attention of general practitioners cannot be excluded. These findings suggest an opportunity for physicians to prescribe varenicline more broadly, even for patients with comorbidities, thereby helping more smokers to quit successfully than do at present.

Abstract
OBJECTIVES Although various effective interventions are available to help individuals quit smoking, the effect of educational levels on cessation rates has rarely been studied, and of the few intervention studies on this topic, the results have been conflicting. DESIGN AND SETTING From October 2008 to August 2013, a partly retrospective non-randomised study was conducted in a smoking cessation clinic of a large general hospital in Beijing, China. PARTICIPANTS In total, 547 Chinese smokers who sought treatment were divided into two groups: a face-to-face counselling group (FC, n=149) and an FC group subjected to four telephone follow-up sessions (FCF, n=398). OUTCOMES We evaluated self-reported cessation rates by day 7 and after 6 and 12 months and stratified the two groups by education levels. RESULTS The 7-day and 6-month and 12-month continuous cessation rates of smokers of low education levels in the FC group at the time of the 12-month follow-up were 12.5%, 7.1% and 7.1%, respectively, which were lower than those of the highly educated smokers (16.1%, 12.9% and 9.7%, respectively). The results were opposite for the FCF group. The corresponding results for the highly educated smokers of the FCF group were 25.0%, 17.2% and 10.3%, respectively, which were lower than those for the smokers of low education levels (28.3%, 22.9% and 18.1%, respectively). However, significant differences were observed only among the FCF group participants who had experienced 12 months of continuous abstinence, and the crude OR for these individuals was recorded at 0.52 (0.29 to 0.93), p=0.03. A stepwise logistic regression showed that education levels may play a role in various intervention methods. Being married and higher Fagerström test scores were also predictors of cessation tendencies. CONCLUSIONS Education levels may affect the benefits of booster counselling sessions on smoking cessation among Chinese smokers.

Abstract
Persistent cigarette smokers usually have a nicotine addiction. This addiction has a chronic relapsing and sometimes remitting course and may persist lifelong. Remission can be facilitated by the use of medication as part of a comprehensive management strategy tailored to the individual patient. Nicotine replacement therapy is a first-line drug treatment. It is available in many formulations. Varenicline is also a first-line drug treatment. It should be started before the patient stops smoking. Bupropion is a second-line therapy. It may be associated with an increased risk of seizures and drug interactions. While there is some evidence that electronic cigarettes might facilitate smoking cessation, quit rates are not yet comparable with those of the drugs approved on the Pharmaceutical Benefits Scheme.

Abstract
Nicotine, as the major psychoactive component of tobacco, has broad physiological effects within the central nervous system, but our understanding of the molecular mechanism underlying its neuronal effects remains incomplete. In this study, we performed a systematic analysis on a set of nicotine addiction-related genes to explore their characteristics at network levels. We found that NAGenes tended to have a more moderate degree and weaker clustering coefficient and to be less central in the network compared to alcohol addiction-related genes or cancer genes. Further, clustering of these genes resulted in six clusters with themes in synaptic transmission, signal transduction, metabolic process, and apoptosis, which provided an intuitional view on the major molecular functions of the genes. Moreover, functional enrichment analysis revealed that neurodevelopment, neurotransmission activity, and metabolism related biological processes were involved in nicotine addiction. In summary, by analyzing the overall characteristics of the nicotine addiction related genes, this study provided valuable information for understanding the molecular mechanisms underlying nicotine addiction.

Abstract
BackgroundThis project examines the organisation and delivery of health improvement activities by and within general practice and the primary health-care team. The project was designed to examine who delivers these interventions, where they are located, what approaches are developed in practices, how individual practices and the primary health-care team organise such public health activities, and how these contribute to health improvement. Our focus was on health promotion and ill-health prevention activities.AimsThe aim of this scoping exercise was to identify the current extent of knowledge about the health improvement activities in general practice and the wider primary health-care team. The key objectives were to provide an overview of the range and type of health improvement activities, identify gaps in knowledge and areas for further empirical research. Our specific research objectives were to map the range and type of health improvement activity undertaken by general practice staff and the primary health-care team based within general practice; to scope the literature on health improvement in general practice or undertaken by health-care staff based in general practice and identify gaps in the evidence base; to synthesise the literature and identify effective approaches to the delivery and organisation of health improvement interventions in a general practice setting; and to identify the priority areas for research as defined by those working in general practice.MethodsWe undertook a comprehensive search of the literature. We followed a staged selection process involving reviews of titles and abstracts. This resulted in the identification of 1140 papers for data extraction, with 658 of these papers selected for inclusion in the review, of which 347 were included in the evidence synthesis. We also undertook 45 individual and two group interviews with primary health-care staff.FindingsMany of the research studies reviewed had some details about the type, process or location, or who provided the intervention. Generally, however, little attention is paid in the literature to examining the impact of the organisational context on the way services are delivered or how this affects the effectiveness of health improvement interventions in general practice. We found that the focus of attention is mainly on individual prevention approaches, with practices engaging in both primary and secondary prevention. The range of activities suggests that general practitioners do not take a population approach but focus on individual patients. However, it is clear that many general practitioners see health promotion as an integral part of practice, whether as individual approaches to primary or secondary health improvement or as a practice-based approach to improving the health of their patients. Our key conclusion is that there is currently insufficient good evidence to support many of the health improvement interventions undertaken in general practice and primary care more widely.Future ResearchFuture research on health improvement in general practice and by the primary health-care team needs to move beyond clinical research to include delivery systems and be conducted in a primary care setting. More research needs to examine areas where there are chronic disease burdens – cancer, dementia and other disabilities of old age. Reviews should be commissioned that examine the whole prevention pathway for health problems that are managed within primary care drawing together research from general practice, pharmacy, community engagement, etc.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
Tobacco smoking remains the leading preventable cause of death and illness in the United States. Smoking cessation is particularly relevant for individuals with chronic obstructive pulmonary disease because it is known from multiple studies that individuals who quit smoking experience an initial improvement in pulmonary function, a decreased rate of normal age-related decline in FEV1, a lower risk of hospital admission, and improved survival. Tobacco dependence must be recognized as a chronic disease, and comprehensive treatment for the tobacco-dependent patient with chronic obstructive pulmonary disease begins with a physician's inquiry into smoking and encouragement to quit, followed by an assessment of the level of dependence and the severity of withdrawal symptoms during previous quit attempts. Combination pharmacotherapy is recommended for the initial treatment of most smokers, especially those with moderate to high baseline levels of tobacco dependence. The patient's history, combined with his or her personal preference, can guide the clinician in initiating an appropriate treatment regimen. Given the chronic nature of tobacco dependence, clinicians must anticipate relapses and the need for recurrent, long-term follow-up. Comprehensive tobacco treatment consultation should be sought whenever possible for patients with high levels of tobacco dependence and multiple relapses or failed quit attempts.

Abstract
OBJECTIVE The aim of the study is to conduct an initial pilot trial evaluating the feasibility, safety, and efficacy of bupropion for smoking cessation in pregnancy. STUDY DESIGN A randomized, double-blind, parallel-group pilot study of bupropion versus placebo with 50 pregnant smokers was planned. Eligibility criteria were restrictive (e.g., 14-26 weeks' gestation; no psychiatric conditions or medications) due to the unknown safety, tolerability, and side effect profile of bupropion in pregnancy. Bayesian analyses were planned to provide probability of benefit. RESULTS Significant challenges were encountered with regard to trial feasibility. Of 820 women screened, 112 were current smokers, but only 11 women were eligible and consented to participate in the study. Excluded women most often had a psychiatric disorder (23%); were outside the gestational range (14%); or declined to participate (11%). CONCLUSIONS This initial attempt to evaluate bupropion for smoking cessation during pregnancy will inform future trial methodology. Because of the unknown safety profile, conservative eligibility criteria were used and resulted in a large portion of this high-risk, low-income smoker population being excluded from the trial, raising questions regarding broad applicability, and highlighting the need to balance patient safety and trial feasibility. Large multisite studies will likely be needed to conduct definitive pharmacotherapy studies.

Abstract
AIMS To evaluate trends in use of stop-smoking medications (SSMs) before and after varenicline (Chantix™) was introduced to the market-place in the United States, and to determine whether varenicline reached segments of the population unlikely to use other SSMs. DESIGN Cohort survey. SETTING United States. PARTICIPANTS A nationally representative sample of adult smokers in the United States interviewed as part of the International Tobacco Control Four Country Survey between 2004 and 2011. Primary analyses used cross-sectional data from 1737 smokers who attempted to quit (∼450 per wave). MEASUREMENTS Reporting an attempt to quit smoking; use of each of the following types of SSMs for the purpose of quitting smoking: nicotine gum, nicotine patch, other nicotine replacement therapy, bupropion and varenicline. FINDINGS There was a significant increase in the rate of use of any SSM among quit attempters across the study period [odds ratio (OR) = 1.15, 95% confidence interval (CI) = 1.10-1.21 per year]. This increase was largest after varenicline was introduced (OR = 1.16, 95% CI = 1.07-1.26 per year); however, there was a decline in nicotine patch use during this time (OR = 0.87, 95% CI = 0.76-0.99 per year). Varenicline users were generally similar to users of other SSMs but differed from those who did not use any SSMs, in that they tended to be older (OR = 5.46, P = 0.024), to be white (OR = 2.33, P = 0.002), to have high incomes (OR = 1.85, P = 0.005), to have high nicotine dependence prior to quitting (OR = 2.40, P = 0.001) and to have used medication in the past (OR = 3.29, P < 0.001). CONCLUSIONS The introduction of varenicline in the United States coincided with a net increase in attempts to quit smoking and, among these, a net increase in use of stop-smoking medications. The demographic profile of varenicline users is similar to the profile of those who use other stop-smoking medications and different from the profile of those who attempt to quit without any medication.
