Abstract
Introduction: Smoking is one of the most important modifiable risk factors for excess morbidity and mortality in adults with serious mental illness (SMI). Many smokers with SMI are reportedly motivated to quit, however success rates among these smokers remain low and evidence-based treatment targeting this vulnerable group is limited. The purpose of this paper is to report the results of a qualitative inquiry of participants. Methods: We conducted a pilot two-arm randomized controlled trial (RCT) targeting adults with SMI. Our smoking cessation intervention included: (a) group-based physical activity (PA) game intervention (50 minutes, 3X/week for 12 weeks), (b) pharmacotherapy (bupropion or nicotine replacement therapy), and (c) smoking cessation counseling. Upon completion of the program, participants in the active and control groups completed a qualitative semi-structured interview in order to determine how the program impacted their smoking cessation. Grounded Theory methodology guided our data collection and analysis. Results: Twenty participants completed an interview. Participants described how the "whole package" of the 3 components of the intervention were critical to their smoking cessation process. The group-based program provided the structure, resources, and encouragement needed to start the process of quitting. Conclusion: Adults with SMI need support, resources, and engaging activities as they begin quitting and practice the skills needed to quit.

Randomized Controlled Trial of Aerobic Exercise for Smoking Cessation Among Individuals With Elevated Depressive Symptoms. Nicotine Tob Res 2024; 26:634-638.

Abstract
INTRODUCTION Adults with depression have higher rates of cigarette smoking and are more likely to relapse than those without depression. Pharmacological, psychological, and combined interventions have largely yielded small improvements in smoking outcomes for adults with depression. Aerobic exercise (AE) may facilitate smoking cessation in this subpopulation. METHODS This study was a 12-week two-arm randomized controlled trial that evaluated the effect of a moderate-intensity AE program compared to a health education contact (HEC) control on smoking cessation in adults with elevated depressive symptoms (mild to severe). Participants (n = 231) were randomized to AE or HEC and received smoking cessation treatment (telephone counseling and nicotine replacement therapy). Primary (biologically confirmed 7-day point prevalence abstinence) and secondary (depressive symptoms, objective and self-reported physical activity, and cardiorespiratory fitness) outcomes were assessed at baseline, 3, 6, and 12 months. Data were analyzed with mixed-effects generalized linear models controlling for age, gender, nicotine dependence, history of major depression disorder, and month of follow-up assessment. RESULTS There were no significant differences in primary or secondary outcomes between the AE and HEC groups. CONCLUSIONS The AE program was not superior to HEC in facilitating smoking cessation, increases in physical activity, or improved depressive symptoms. Given evidence for the positive acute effects of exercise on mood and smoking urges, future research should consider testing alternative exercise approaches for aiding smoking cessation beyond structured, AE programs. IMPLICATIONS This study found that an adjunctive aerobic exercise (AE) program was not superior to a health education contact control for adults with elevated depressive symptoms, all of whom also received standard smoking cessation treatment. This finding adds to the growing body of literature that structured AE programs for smoking cessation may have limited efficacy for cessation outcomes. Future research is needed to test alternative methods of integrating AE into smoking cessation treatment, such as strategically using exercise to manage cravings and low mood in the moment.

The Efficacy of Individualized, Community-Based Physical Activity to Aid Smoking Cessation: A Randomized Controlled Trial. J Smok Cessat 2023; 2023:5535832. [PMID: 37273658 PMCID: PMC10238145 DOI: 10.1155/2023/5535832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 02/14/2023] [Accepted: 05/10/2023] [Indexed: 06/06/2023] Open
Abstract
Objective The efficacy of individualized, community-based physical activity as an adjunctive smoking cessation treatment to enhance long-term smoking cessation rates was evaluated for the Lifestyle Enhancement Program (LEAP). Methods The study was a two-arm, parallel-group, randomized controlled trial. All participants (n = 392) received cessation counseling and a nicotine patch and were randomized to physical activity (n = 199; YMCA membership and personalized exercise programming from a health coach) or an equal contact frequency wellness curriculum (n = 193). Physical activity treatment was individualized and flexible (with each participant selecting types of activities and intensity levels and being encouraged to exercise at the YMCA and at home, as well as to use "lifestyle" activity). The primary outcome (biochemically verified prolonged abstinence at 7-weeks (end of treatment) and 6- and 12-months postcessation) and secondary outcomes (7-day point prevalent tobacco abstinence (PPA), total minutes per week of leisure time physical activity and strength training) were assessed at baseline, 7 weeks, 6 months, and 12 months. Results Prolonged abstinence in the physical activity and wellness groups was 19.6% and 25.4%, respectively, at 7-weeks, 15.1% and 16.6% at 6-months, and 14.1% and 17.1% at 12 months (all between-group P values >0.18). Similarly, PPA rates did not differ significantly between groups at any follow-up. Change from baseline leisure-time activity plus strength training increased significantly in the physical activity group at 7 weeks (P = 0.04). Across treatment groups, an increase in the number of minutes per week in strength training from baseline to 7 weeks predicted prolonged abstinence at 12 months (P ≤ 0.001). Further analyses revealed that social support, fewer years smoked, and less temptation to smoke were associated with prolonged abstinence over 12 months in both groups. Conclusions Community-based physical activity programming, delivered as adjunctive treatment with behavioral/pharmacological cessation treatment, did not improve long-term quit rates compared to adjunctive wellness counseling plus behavioral/pharmacological cessation treatment. This trial is registered with https://beta.clinicaltrials.gov/study/NCT00403312, registration no. NCT00403312.

Front Physiol 2023; 14:1126777. [PMID: 37234417 PMCID: PMC10208401 DOI: 10.3389/fphys.2023.1126777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Accepted: 04/17/2023] [Indexed: 05/28/2023] Open
Abstract
Background: Exercise can effectively attenuate withdrawal symptoms and reduce relapse, but it is unknown whether exercise of different intensities produces different results. This study aimed to systematically review the effects of different exercise intensities on withdrawal symptoms among people with substance use disorder (SUD). Methods: Systematic searches for randomized controlled trials (RCTs) on exercise, SUD, and abstinence symptoms were conducted via electronic databases, including PubMed, up to June 2022. Study quality was evaluated using the Cochrane Risk of Bias tool (RoB 2.0) for assessment of risk of bias in randomized trials. The meta-analysis was performed by calculating the standard mean difference (SMD) in outcomes of interventions involving light-, moderate-, and high-intensity exercise for each individual study using Review Manager version 5.3 (RevMan 5.3). Results: In total, 22 RCTs (n = 1,537) were included. Overall, exercise interventions had significant effects on withdrawal symptoms, but the effect size varied with exercise intensity and by outcome measure (i.e., for different negative emotions). Light-, moderate-, and high-intensity exercise reduced cravings after the intervention [SMD = -0.71, 95% CI = (-0.90, -0.52)], and there were no statistical differences between the subgroups (p > 0.05). Light-, moderate-, and high-intensity exercise reduced depression after the intervention [light, SMD = -0.33, 95% CI = (-0.57, -0.09); moderate, SMD = -0.64, 95% CI = (-0.85, -0.42); high, SMD = -0.25, 95% CI = (-0.44, -0.05)], with moderate-intensity exercise producing the best effect (p < 0.05). Only light- and moderate-intensity exercise relieved anxiety after the intervention [light, SMD = -0.48, 95% CI = (-0.71, -0.26); moderate, SMD = -0.58, 95% CI = (-0.85, -0.31)]. Only high-intensity exercise worked in alleviating stress [SMD = -1.13, 95% CI = (-2.22, -0.04)]. Both irritability and restlessness could be improved by light- and moderate-intensity exercise [irritability, SMD = -0.74, 95% CI = (-0.98, -0.50); restless, SMD = -0.72, 95% CI = (-0.98, -0.47)], and there were no statistical differences between the subgroups (p > 0.05). Moderate- and high-intensity exercise decreased withdrawal syndrome after the intervention [moderate, SMD = -0.30, 95% CI = (-0.55, -0.05); high, SMD = -1.33, 95% CI = (-1.90, -0.76)], with high-intensity exercise producing the best effects (p < 0.01). Conclusion: Overall, exercise leads to improvements in withdrawal symptoms in individuals with SUD, but these effects vary significantly between the exercise of different intensities and according to the type of withdrawal symptoms. Moderate-intensity exercise has the greatest benefits in improving depression and anxiety; high-intensity exercise has the greatest benefits in improving withdrawal syndrome.

Add-on exercise interventions for smoking cessation in people with mental illness: a systematic review and meta-analysis. BMC Sports Sci Med Rehabil 2022; 14:115.

Abstract
BACKGROUND Smoking is the most common substance use disorder among people with mental illness. In contrast to people without mental illness, among whom the proportion of smokers has declined in recent decades, the proportion of smokers among people with mental illness remains high. There is a growing body of literature suggesting the use of exercise interventions in combination with smoking cessation in people without mental illness, but to our knowledge the available studies on this treatment option in people with mental illness have not been systematically reviewed. Therefore, this systematic review and meta-analysis aims to assess the effectiveness of exercise interventions as an adjunctive treatment for smoking cessation in people with mental illness. METHODS Electronic databases (PubMed, Web of Science, PsycInfo, Sport Discus and Base) were searched for randomised controlled trials and prospective single-group studies that investigated exercise interventions in combination with smoking cessation programmes alone or in comparison with a control group in people with mental illness. A meta-analysis using the Mantel-Haenszel fixed-effect model was conducted to estimate the overall effect of treatment on smoking cessation (abstinence rate at the end of the intervention and at 6-month follow-up). RESULTS Six studies, five randomised controlled trials and one study with a prospective single-group design, were included in the systematic review and four randomised controlled trials were included in the meta-analysis. The meta-analysis found a significantly higher abstinence rate after additional exercise at the end of the intervention [risk ratio (RR) 1.48, 95% confidence interval (CI) 1.13-1.94], but not at the 6-month follow-up (RR 1.34, 95% CI 0.89-2.04). CONCLUSIONS Exercise appears to be an effective adjunctive therapy to temporarily increase abstinence rates in individuals with mental illness at the end of the intervention. However, due to the small number of included studies and some risk of bias in the included studies, the results should be treated with caution. Therefore, future studies with larger samples are needed to provide a more accurate estimate of the effect in people with mental illness. Registration The systematic review and meta-analysis were registered in the International Prospective Register of Systematic Reviews (PROSPERO) (registration number: CRD42020178630).

Abstract
BACKGROUND There is a worldwide struggle to quit smoking and prevent relapsing. Aerobic exercises are frequently utilized to aid in smoking cessation and prevent relapse. AIMS This study aimed to investigate the effects of aerobic exercises of different intensity on the level of anxiety, smoking addiction, and quality of sleep and life in former smokers. METHODS The study included 60 people aged 18 to 45 who had quit smoking within the previous month. Individuals were randomly assigned to control (CON), mild-intensity aerobic activity (MIA), and moderate-intensity aerobic activity (MoIA) groups. The MIA group did submaximal aerobic exercises at 40% of maximum heart rate (MHR), while the MoIA group did them at 60% of MHR for 8 weeks/3 days. Participants' anxiety levels were assessed using the Beck Anxiety Scale (BAS), smoking addiction was assessed using the Fagerström Test for Nicotine Dependence and Substance Craving Scale (SCS), sleep quality was assessed using the Pittsburgh Sleep Quality Index, and quality of life was assessed using the SF-36 Short Form Scale (SF-36). RESULTS The SCS score of the MoIA group declined more than the MIA and CON groups, and the MIA group had a lower sleep disturbance score than other groups when the influence of exercise training was assessed over time (p < 0.05). Aerobic exercise had no influence on SF-36 or BAS scores (p > 0.05). CONCLUSIONS The benefits of mild and moderate aerobic exercise on quality of life and anxiety are similar. However, mild-intensity aerobic exercises may be suitable for sleep difficulties while moderate-intensity aerobic exercises may be preferred for reducing smoking addiction.

Abstract
Despite the prevalence and public health impact of substance use disorders (SUDs), effective long-term treatments remain elusive. Aerobic exercise is a promising, nonpharmacological treatment currently under investigation as a strategy for preventing drug relapse. Aerobic exercise could be incorporated into the comprehensive treatment regimens for people with substance abuse disorders. Preclinical studies of SUD with animal models have shown that aerobic exercise diminishes drug-seeking behavior, which leads to relapse, in both male and female rats. Nevertheless, little is known regarding the effects of substance abuse-induced cellular and physiological adaptations believed to be responsible for drug-seeking behavior. Accordingly, the overall goal of this review is to provide a summary and an assessment of findings to date, highlighting evidence of the molecular and neurological effects of exercise on adaptations associated with SUD.

Abstract
BACKGROUND Most people who stop smoking gain weight. This can discourage some people from making a quit attempt and risks offsetting some, but not all, of the health advantages of quitting. Interventions to prevent weight gain could improve health outcomes, but there is a concern that they may undermine quitting. OBJECTIVES To systematically review the effects of: (1) interventions targeting post-cessation weight gain on weight change and smoking cessation (referred to as 'Part 1') and (2) interventions designed to aid smoking cessation that plausibly affect post-cessation weight gain (referred to as 'Part 2'). SEARCH METHODS Part 1 - We searched the Cochrane Tobacco Addiction Group's Specialized Register and CENTRAL; latest search 16 October 2020. Part 2 - We searched included studies in the following 'parent' Cochrane reviews: nicotine replacement therapy (NRT), antidepressants, nicotine receptor partial agonists, e-cigarettes, and exercise interventions for smoking cessation published in Issue 10, 2020 of the Cochrane Library. We updated register searches for the review of nicotine receptor partial agonists. SELECTION CRITERIA Part 1 - trials of interventions that targeted post-cessation weight gain and had measured weight at any follow-up point or smoking cessation, or both, six or more months after quit day. Part 2 - trials included in the selected parent Cochrane reviews reporting weight change at any time point. DATA COLLECTION AND ANALYSIS Screening and data extraction followed standard Cochrane methods. Change in weight was expressed as difference in weight change from baseline to follow-up between trial arms and was reported only in people abstinent from smoking. Abstinence from smoking was expressed as a risk ratio (RR). Where appropriate, we performed meta-analysis using the inverse variance method for weight, and Mantel-Haenszel method for smoking. MAIN RESULTS Part 1: We include 37 completed studies; 21 are new to this update. We judged five studies to be at low risk of bias, 17 to be at unclear risk and the remainder at high risk. An intermittent very low calorie diet (VLCD) comprising full meal replacement provided free of charge and accompanied by intensive dietitian support significantly reduced weight gain at end of treatment compared with education on how to avoid weight gain (mean difference (MD) -3.70 kg, 95% confidence interval (CI) -4.82 to -2.58; 1 study, 121 participants), but there was no evidence of benefit at 12 months (MD -1.30 kg, 95% CI -3.49 to 0.89; 1 study, 62 participants). The VLCD increased the chances of abstinence at 12 months (RR 1.73, 95% CI 1.10 to 2.73; 1 study, 287 participants). However, a second study found that no-one completed the VLCD intervention or achieved abstinence. Interventions aimed at increasing acceptance of weight gain reported mixed effects at end of treatment, 6 months and 12 months with confidence intervals including both increases and decreases in weight gain compared with no advice or health education. Due to high heterogeneity, we did not combine the data. These interventions increased quit rates at 6 months (RR 1.42, 95% CI 1.03 to 1.96; 4 studies, 619 participants; I2 = 21%), but there was no evidence at 12 months (RR 1.25, 95% CI 0.76 to 2.06; 2 studies, 496 participants; I2 = 26%). Some pharmacological interventions tested for limiting post-cessation weight gain (PCWG) reduced weight gain at the end of treatment (dexfenfluramine, phenylpropanolamine, naltrexone). The effects of ephedrine and caffeine combined, lorcaserin, and chromium were too imprecise to give useful estimates of treatment effects. There was very low-certainty evidence that personalized weight management support reduced weight gain at end of treatment (MD -1.11 kg, 95% CI -1.93 to -0.29; 3 studies, 121 participants; I2 = 0%), but no evidence in the longer-term 12 months (MD -0.44 kg, 95% CI -2.34 to 1.46; 4 studies, 530 participants; I2 = 41%). There was low to very low-certainty evidence that detailed weight management education without personalized assessment, planning and feedback did not reduce weight gain and may have reduced smoking cessation rates (12 months: MD -0.21 kg, 95% CI -2.28 to 1.86; 2 studies, 61 participants; I2 = 0%; RR for smoking cessation 0.66, 95% CI 0.48 to 0.90; 2 studies, 522 participants; I2 = 0%). Part 2: We include 83 completed studies, 27 of which are new to this update. There was low certainty that exercise interventions led to minimal or no weight reduction compared with standard care at end of treatment (MD -0.25 kg, 95% CI -0.78 to 0.29; 4 studies, 404 participants; I2 = 0%). However, weight was reduced at 12 months (MD -2.07 kg, 95% CI -3.78 to -0.36; 3 studies, 182 participants; I2 = 0%). Both bupropion and fluoxetine limited weight gain at end of treatment (bupropion MD -1.01 kg, 95% CI -1.35 to -0.67; 10 studies, 1098 participants; I2 = 3%); (fluoxetine MD -1.01 kg, 95% CI -1.49 to -0.53; 2 studies, 144 participants; I2 = 38%; low- and very low-certainty evidence, respectively). There was no evidence of benefit at 12 months for bupropion, but estimates were imprecise (bupropion MD -0.26 kg, 95% CI -1.31 to 0.78; 7 studies, 471 participants; I2 = 0%). No studies of fluoxetine provided data at 12 months. There was moderate-certainty that NRT reduced weight at end of treatment (MD -0.52 kg, 95% CI -0.99 to -0.05; 21 studies, 2784 participants; I2 = 81%) and moderate-certainty that the effect may be similar at 12 months (MD -0.37 kg, 95% CI -0.86 to 0.11; 17 studies, 1463 participants; I2 = 0%), although the estimates are too imprecise to assess long-term benefit. There was mixed evidence of the effect of varenicline on weight, with high-certainty evidence that weight change was very modestly lower at the end of treatment (MD -0.23 kg, 95% CI -0.53 to 0.06; 14 studies, 2566 participants; I2 = 32%); a low-certainty estimate gave an imprecise estimate of higher weight at 12 months (MD 1.05 kg, 95% CI -0.58 to 2.69; 3 studies, 237 participants; I2 = 0%). AUTHORS' CONCLUSIONS Overall, there is no intervention for which there is moderate certainty of a clinically useful effect on long-term weight gain. There is also no moderate- or high-certainty evidence that interventions designed to limit weight gain reduce the chances of people achieving abstinence from smoking.

Carroll ME. Voluntary exercise as a treatment for incubated and expanded drug craving leading to relapse to addiction: Animal models. Pharmacol Biochem Behav 2021; 208:173210. [PMID: 34116079 DOI: 10.1016/j.pbb.2021.173210] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Revised: 05/25/2021] [Accepted: 05/26/2021] [Indexed: 02/08/2023]
Abstract
Drug addiction is a chronic relapsing disorder, as more than 80% of former drug users relapse within a year after quit attempts have ended. This review examines incubated craving that develops over long periods of weeks to months after addictive drug use ends, when rats are given a small priming exposure to the formerly used drug, and a large amount of drug seeking occurs, reflecting large increases in craving over time. Expanded craving occurs when not only the recently-used drug, but other related or unrelated drugs of abuse elicit drug seeking that leads to relapse behavior, including common drugs like caffeine or nicotine, Thus, expanded craving is an increase in the conditions that elicit relapse, such as, a variety of drugs, and it persists weeks after drug use ends. Incubated and expanded craving occur with several drugs of abuse, and these forms of craving, can last for weeks to months and end in relapse. Voluntary physical exercise, blocked incubated cocaine craving, and expanded heroin craving elicited by multiple conditions was reduced in female and male rats. This review examines voluntary physical exercise as a long-term, self-initiated, and self-sustainable treatment that reduces long-term drug craving leading to relapse.

Musculoskeletal Care 2021; 19:319-330. [PMID: 33629803 DOI: 10.1002/msc.1542] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Revised: 01/31/2021] [Accepted: 02/01/2021] [Indexed: 12/16/2022]
Abstract
BACKGROUND Plantar heel pain (PHP) is considered a tendinopathy and it affects up to 10% of the population. Both heavy slow resistance training (HSRT) and extracorporeal shockwave therapy (ESWT) have shown effectiveness for treating PHP in isolation. However, more comprehensive exercise protocols and progression methods are needed due to poor long-term outcomes, and better standardisation of ESWT protocols are required. Autoregulation of resistance training involves self-selecting exercise dosage based on individual factors. Although autoregulation has proven effective for strength gains in athletes, it has not been investigated in tendinopathy. Recent studies recommend that PHP should not be treated by one treatment intervention in isolation. However, there is a dearth of research investigating the feasibility and effectiveness of combined treatment interventions for PHP. Currently, no studies have investigated autoregulated HSRT combined with ESWT, despite their individual efficacy. The optimal treatment protocol for PHP is unknown, and there is a need to ascertain whether the addition of ESWT to autoregulated HSRT leads to better outcomes compared to either alone. METHODS A three-arm randomised controlled trial (RCT) comparing these groups would be the ideal way to investigate this question, with a pilot RCT testing trial procedures and process evaluation required prior to a definitive RCT. Patients expectations, feasibility and acceptability of combined ESWT and exercise for PHP also remain unknown. Therefore, the addition of qualitative interviews in a mixed-methods pilot RCT would help ascertain acceptability and help explain the intervention outcomes.

Effectiveness of Aerobic Exercise on Smoking Cessation in Adults: A Systematic Review and Meta-Analysis. J Phys Act Health 2021; 18:230-242. [PMID: 33434887 DOI: 10.1123/jpah.2019-0339] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 08/19/2020] [Accepted: 10/06/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND The specific benefits of aerobic exercises in smoking cessation are unclear, as they have different characteristics, intensities, and durations. The purpose of this systematic review with meta-analysis was to evaluate the effects of aerobic exercise, with or without co-interventions, compared with a control group of cognitive behavior treatment on smoking cessation. METHODS This review was prospectively registered on PROSPERO, and the searches were performed from 2016 to 2018. Randomized controlled trials evaluating the effects of aerobic exercise, with or without nicotine therapy replacement, compared with usual care were included. The primary outcome was smoking cessation defined as the prevalence of those who quit or continuous abstinence. Meta-analysis was calculated using random effects model in the comprehensive meta-analysis software. RESULTS The authors identified 18 trials reporting data for a total of 2815 participants. There was moderate-quality evidence that aerobic exercise was better than usual care in promoting smoking cessation at short term (11 trials, risk ratio 0.79; 95% confidence interval, 0.66-0.94). However, there were no differences between aerobic exercises and usual care at medium- or long-term follow-ups. CONCLUSIONS According to review, aerobic exercise may be effective in promoting smoking cessation at short-term, but not at medium- and long-term follow-ups.

Abstract
Major depression is associated with premature mortality, largely explained by heightened cardiovascular burden. This narrative review summarizes secondary literature (i.e., reviews and meta-analyses) on this topic, considering physical exercise as a potential tool to counteract this alarming phenomenon. Compared to healthy controls, individuals with depression consistently present heightened cardiovascular risk, including "classical" risk factors and dysregulation of pertinent homeostatic systems (immune system, hypothalamic-pituitary-adrenal axis and autonomic nervous system). Ultimately, both genetic background and behavioral abnormalities contribute to explain the link between depression and cardiovascular mortality. Physical inactivity is particularly common in depressed populations and may represent an elective therapeutic target to address premature mortality. Exercise-based interventions, in fact, have proven effective reducing cardiovascular risk and mortality through different mechanisms, although evidence still needs to be replicated in depressed populations. Notably, exercise also directly improves depressive symptoms. Despite its potential, however, exercise remains under-prescribed to depressed individuals. Public health may be the ideal setting to develop and disseminate initiatives that promote the prescription and delivery of exercise-based interventions, with a particular focus on their cost-effectiveness.

Abstract
INTRODUCTION Isometric exercises reduce craving, negative affect, and withdrawal symptoms during smoking cessation. This randomized controlled trial (RCT) was the first to test if a brief intervention using a handgrip and isometric exercises including hand pushing/pulling was feasible and efficacious to increase tobacco abstinence at 6-month. METHODS This was a single-blinded, 2-arm pilot RCT in 6 community-based smoking cessation clinics in Hong Kong. Smokers who consumed 10 or more cigarettes a day and were receiving cessation services were randomized to the exercise group (n = 108) who received a free handgrip and a leaflet about handgrip exercise, and watched a 5-minute video, or to the healthy-diet group (n = 100) who receive a similar dosage of intervention on healthy diet. The primary outcome was self-reported abstinence in the previous 4 weeks at 6-month follow-up. RESULTS In the exercise group, about 36% reported doing the exercises when craving at 2-month follow-up. No significant difference in quit rate was found between groups (34% vs. 39%, OR = 0.80, P = .40). A posteriori analysis on the exercise group showed that self-reported exercises when craving (49% vs. 26%, OR = 2.69, 1.18-6.15, P = .02) and total adherence (including doing the exercises when craving, once a day, and/or for 2 weeks) (53% vs. 23%, OR = 3.70, 1.15-11.92, P = .03) were significantly associated with self-reported abstinence. CONCLUSIONS The brief handgrip/isometric exercise intervention was feasible and achieved modest adherence without offering incentives or mandatory reminders. Preliminary evidence of benefits was observed in the intervention group if the exercises were done when craving. IMPLICATIONS Our study indicates that a brief exercise intervention, including a free handgrip and educational video, was feasible for smokers receiving smoking cessation treatment. It was particularly efficacious in increasing tobacco abstinence when exercise adherence was high. TRIAL REGISTRATION ClinicalTrial.gov (NCT02844296).

Abstract
Addiction to drug and alcohol is regarded as a major health problem worldwide for which available treatments show limited effectiveness. The biggest challenge remains to enhance the capacities of interventions to reduce craving, prevent relapse and promote long-term recovery. New strategies to meet these challenges are being explored. Findings from preclinical work suggest that environmental enrichment (EE) holds therapeutic potential for the treatment of substance use disorders, as demonstrated in a number of animal models of drug abuse. The EE intervention introduced after drug exposure leads to attenuation of compulsive drug taking, attenuation of the rewarding (and reinforcing) effects of drugs, reductions in control of behavior by drug cues, and, very importantly, relapse prevention. Clinical work also suggests that multidimensional EE interventions (involving physical activity, social interaction, vocational training, recreational and community involvement) might produce similar therapeutic effects, if implemented continuously and rigorously. In this review we survey preclinical and clinical studies assessing the efficacy of EE as a behavioral intervention for substance use disorders and address related challenges. We also review work providing empirical evidence for EE-induced neuroplasticity within the mesocorticolimbic system that is believed to contribute to the seemingly therapeutic effects of EE on drug and alcohol-related behaviors.

Abstract
BACKGROUND Taking regular exercise, whether cardiovascular-type exercise or resistance exercise, may help people to give up smoking, particularly by reducing cigarette withdrawal symptoms and cravings, and by helping to manage weight gain. OBJECTIVES To determine the effectiveness of exercise-based interventions alone, or combined with a smoking cessation programme, for achieving long-term smoking cessation, compared with a smoking cessation intervention alone or other non-exercise intervention. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register for studies, using the term 'exercise' or 'physical activity' in the title, abstract or keywords. The date of the most recent search was May 2019. SELECTION CRITERIA We included randomised controlled trials that compared an exercise programme alone, or an exercise programme as an adjunct to a cessation programme, with a cessation programme alone or another non-exercise control group. Trials were required to recruit smokers wishing to quit or recent quitters, to assess abstinence as an outcome and have follow-up of at least six months. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods. Smoking cessation was measured after at least six months, using the most rigorous definition available, on an intention-to-treat basis. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) for smoking cessation for each study, where possible. We grouped eligible studies according to the type of comparison, as either smoking cessation or relapse prevention. We carried out meta-analyses where appropriate, using Mantel-Haenszel random-effects models. MAIN RESULTS We identified 24 eligible trials with a total of 7279 adult participants randomised. Two studies focused on relapse prevention among smokers who had recently stopped smoking, and the remaining 22 studies were concerned with smoking cessation for smokers who wished to quit. Eleven studies were with women only and one with men only. Most studies recruited fairly inactive people. Most of the trials employed supervised, group-based cardiovascular-type exercise supplemented by a home-based exercise programme and combined with a multi-session cognitive behavioural smoking cessation programme. The comparator in most cases was a multi-session cognitive behavioural smoking cessation programme alone. Overall, we judged two studies to be at low risk of bias, 11 at high risk of bias, and 11 at unclear risk of bias. Among the 21 studies analysed, we found low-certainty evidence, limited by potential publication bias and by imprecision, comparing the effect of exercise plus smoking cessation support with smoking cessation support alone on smoking cessation outcomes (RR 1.08, 95% CI 0.96 to 1.22; I2 = 0%; 6607 participants). We excluded one study from this analysis as smoking abstinence rates for the study groups were not reported. There was no evidence of subgroup differences according to the type of exercise promoted; the subgroups considered were: cardiovascular-type exercise alone (17 studies), resistance training alone (one study), combined cardiovascular-type and resistance exercise (one study) and type of exercise not specified (two studies). The results were not significantly altered when we excluded trials with high risk of bias, or those with special populations, or those where smoking cessation intervention support was not matched between the intervention and control arms. Among the two relapse prevention studies, we found very low-certainty evidence, limited by risk of bias and imprecision, that adding exercise to relapse prevention did not improve long-term abstinence compared with relapse prevention alone (RR 0.98, 95% CI 0.65 to 1.47; I2 = 0%; 453 participants). AUTHORS' CONCLUSIONS There is no evidence that adding exercise to smoking cessation support improves abstinence compared with support alone, but the evidence is insufficient to assess whether there is a modest benefit. Estimates of treatment effect were of low or very low certainty, because of concerns about bias in the trials, imprecision and publication bias. Consequently, future trials may change these conclusions.

Abstract
BACKGROUND Pharmacotherapies for smoking cessation increase the likelihood of achieving abstinence in a quit attempt. It is plausible that providing support, or, if support is offered, offering more intensive support or support including particular components may increase abstinence further. OBJECTIVES To evaluate the effect of adding or increasing the intensity of behavioural support for people using smoking cessation medications, and to assess whether there are different effects depending on the type of pharmacotherapy, or the amount of support in each condition. We also looked at studies which directly compare behavioural interventions matched for contact time, where pharmacotherapy is provided to both groups (e.g. tests of different components or approaches to behavioural support as an adjunct to pharmacotherapy). SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the ICTRP in June 2018 for records with any mention of pharmacotherapy, including any type of nicotine replacement therapy (NRT), bupropion, nortriptyline or varenicline, that evaluated the addition of personal support or compared two or more intensities of behavioural support. SELECTION CRITERIA Randomised or quasi-randomised controlled trials in which all participants received pharmacotherapy for smoking cessation and conditions differed by the amount or type of behavioural support. The intervention condition had to involve person-to-person contact (defined as face-to-face or telephone). The control condition could receive less intensive personal contact, a different type of personal contact, written information, or no behavioural support at all. We excluded trials recruiting only pregnant women and trials which did not set out to assess smoking cessation at six months or longer. DATA COLLECTION AND ANALYSIS For this update, screening and data extraction followed standard Cochrane methods. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically-validated rates, if available. We calculated the risk ratio (RR) and 95% confidence interval (CI) for each study. Where appropriate, we performed meta-analysis using a random-effects model. MAIN RESULTS Eighty-three studies, 36 of which were new to this update, met the inclusion criteria, representing 29,536 participants. Overall, we judged 16 studies to be at low risk of bias and 21 studies to be at high risk of bias. All other studies were judged to be at unclear risk of bias. Results were not sensitive to the exclusion of studies at high risk of bias. We pooled all studies comparing more versus less support in the main analysis. Findings demonstrated a benefit of behavioural support in addition to pharmacotherapy. When all studies of additional behavioural therapy were pooled, there was evidence of a statistically significant benefit from additional support (RR 1.15, 95% CI 1.08 to 1.22, I² = 8%, 65 studies, n = 23,331) for abstinence at longest follow-up, and this effect was not different when we compared subgroups by type of pharmacotherapy or intensity of contact. This effect was similar in the subgroup of eight studies in which the control group received no behavioural support (RR 1.20, 95% CI 1.02 to 1.43, I² = 20%, n = 4,018). Seventeen studies compared interventions matched for contact time but that differed in terms of the behavioural components or approaches employed. Of the 15 comparisons, all had small numbers of participants and events. Only one detected a statistically significant effect, favouring a health education approach (which the authors described as standard counselling containing information and advice) over motivational interviewing approach (RR 0.56, 95% CI 0.33 to 0.94, n = 378). AUTHORS' CONCLUSIONS There is high-certainty evidence that providing behavioural support in person or via telephone for people using pharmacotherapy to stop smoking increases quit rates. Increasing the amount of behavioural support is likely to increase the chance of success by about 10% to 20%, based on a pooled estimate from 65 trials. Subgroup analysis suggests that the incremental benefit from more support is similar over a range of levels of baseline support. More research is needed to assess the effectiveness of specific components that comprise behavioural support.

Abstract
Background: In the past 3 decades, there has been an increase in the number of studies assessing exercise as a form of treatment for substance use disorders (SUDs). While a variety of substance types and outcomes have been assessed, exercise intensities have never been systematically examined. Consequently, it remains unclear whether particular forms of exercise are better suited to the treatment of these populations. Anaerobic exercise has been shown to have positive effects in populations with psychiatric disorders, but its effectiveness in the treatment of SUDs has to date not been reviewed. Methods: The aim of this systematic review is to identify and evaluate studies which have employed either an acute or chronic anaerobic exercise component as a therapy modality for SUDs. The primary outcomes are abstinence, craving, withdrawal, consumption, quality of life, and the following psychological symptoms and disorders: depression, anxiety, stress, and mood. A secondary objective is to assess whether the type of training described in the study protocol can be reliably categorized as anaerobic training. Results: Twenty-six studies are included in this review. Twelve studies addressed nicotine dependence, one addressed alcohol dependence, and 13 addressed dependence on various illicit drugs. Thirteen studies reported the intensity at which participants actually exercised, but only one employed a test to determine whether training was carried out above the anaerobic threshold (AT). The risk of bias in the included studies was generally high. Results of the studies were mixed, with the most positive effects being found for abstinence in nicotine dependence. Conclusion: The evidence for the effects of anaerobic exercise in SUDs is weak, although a tendency toward positive effects on abstinence in nicotine dependent individuals was observable. The majority of studies do not report data on exercise intensity, making a categorization of anaerobic exercise impossible in all but one case. This means that the effects of this form of exercise cannot be determined, and therefore not evaluated or compared with other forms. In order to improve the quality of evidence for exercise in SUD treatment, clearly defined and objectively assessed evaluations of anaerobic and anaerobic exercise are necessary.

Abstract
Social support may be an effective strategy to increase engagement in cessation treatment for smokers with mental illness. The purpose of this pilot study was to assess the feasibility of a support person intervention linking smokers with mental illness to an online smoking cessation decision aid. We conducted a 12-week pilot study of a one-session telephone coaching intervention ("Care2Quit") to train nonsmoking family members and friends (i.e., support persons) to promote the use of an online cessation decision aid by smokers with mental illness. The primary aim of the study was to assess the feasibility of the support person intervention by examining recruitment, retention, adherence, and participant satisfaction. A secondary aim was to explore changes in the hypothesized mechanism underlying the intervention effect (i.e., cessation support provided) and primary outcome (i.e., smoker use of online cessation decision aid). Seventeen support persons enrolled, of which 94% (n = 16) completed the telephone coaching intervention. Eighty-eight percent of support persons rated the intervention as highly acceptable. Self-reported cessation supportive behaviors by the support person increased significantly by 6 weeks post intervention. Forty-one percent of smokers (n = 7) linked to support persons used the online cessation decision aid by 12 weeks following the support person's telephone coaching session. Preliminary results from this study demonstrate the feasibility of a support person intervention to promote the use of smoking cessation treatment among smokers with mental illness. Future research to evaluate the efficacy of the Care2Quit support partner intervention is warranted.

Abstract
BACKGROUND Clinical trials of physical activity and rehabilitation interventions can be challenging. Pilot or feasibility studies can be conducted prior to a definitive randomized controlled trial (RCT), to improve the chances of conducting a high-quality RCT of a physical activity intervention. MAIN BODY Physical activity interventions or trials present unique challenges at the population, intervention, comparator and outcome levels. At each level, we present guidance for researchers on the design considerations for pilot or feasibility studies of physical activity interventions. When it comes to defining study population, physical activity trials often exclude participants with certain health conditions or other characteristics (e.g., age, gender) because of uncertainty of the safety of the exercise intervention or presumed differences in responsiveness, at the expense of trial generalizability. A pilot trial could help investigators determine refined inclusion and exclusion criteria to balance safety, adequate recruitment, and generalizability. At the intervention level, because exercise can be a complex intervention, pilot trials allow investigators to evaluate participant adherence and instructor fidelity to the intervention and participant experience. At the comparator level, control group dissatisfaction and post-randomization drop-out can occur, because of the desire to be randomized to the exercise group, and the difficulty with blinding to group allocation; an active control or deception could be used. Finally, at the outcome level, there should be an emphasis on the pilot or feasibility outcomes such as recruitment rate, adherence to exercise, and retention or fidelity, than the efficacy of the exercise intervention. CONCLUSION Physical activity and rehabilitation researchers can use pilot and feasibility studies to enhance the rigor of future trials, while also publishing the results of their pilot work to move the field forward. Researchers in this field are encouraged to use published reporting guidelines for pilot and feasibility studies and to consider the challenges discussed in this paper.

Survey of potential receptivity to robotic-assisted exercise coaching in a diverse sample of smokers and nonsmokers. PLoS One 2018; 13:e0197090. [PMID: 29746530 PMCID: PMC5944940 DOI: 10.1371/journal.pone.0197090] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2017] [Accepted: 04/26/2018] [Indexed: 11/19/2022] Open
Abstract
A prior project found that an intensive (12 weeks, thrice weekly sessions) in-person, supervised, exercise coaching intervention was effective for smoking cessation among depressed women smokers. However, the sample was 90% White and of high socioeconomic status, and the intensity of the intervention limits its reach. One approach to intervention scalability is to deliver the supervised exercise coaching using a robotic human exercise trainer. This is done in real time via an iPad tablet placed on a mobile robotic wheel base and controlled remotely by an iOS device or computer. As an initial step, this preliminary study surveyed potential receptivity to a robotic-assisted exercise coaching intervention among 100 adults recruited in two community settings, and explored the association of technology acceptance scores with smoking status and other demographics. Participants watched a brief demonstration of the robot-delivered exercise coaching and completed a 19-item survey assessing socio-demographics and technology receptivity measured by the 8-item Technology Acceptance Scale (TAS). Open-ended written feedback was obtained, and content analysis was used to derive themes from these data. Respondents were: 40% female, 56% unemployed, 41% racial minority, 38% current smoker, and 58% depression history. Mean total TAS score was 34.0 (SD = 5.5) of possible 40, indicating overall very good receptivity to the robotic-assisted exercise intervention concept. Racial minorities and unemployed participants reported greater technology acceptance than White (p = 0.015) and employed (p<0.001) respondents. No association was detected between the TAS score and smoking status, depression, gender or age groups. Qualitative feedback indicated the robot was perceived as a novel, motivating, way to increase intervention reach and accessibility, and the wave of the future. Robotic technology has potential applicability for exercise coaching in a broad range of populations, including depressed smokers. Our next step will be to conduct a pilot trial to assess acceptability and potential efficacy of the robotic-assisted exercise coaching intervention for smoking cessation.

Abstract
Despite advances in behavioral and pharmacological treatment for tobacco use and dependence, quit rates remain suboptimal. Increasing physical activity has shown some promise as a strategy for improving cessation outcomes. However, initial efficacy studies focused on intensive, highly structured exercise programs that may not be applicable to the general population of smokers. We describe the rationale and study design and report baseline participant characteristics from the Lifestyle Enhancement Program (LEAP), a two-group, randomized controlled trial. Adult smokers who engaged in low levels of leisure time physical activity were randomly assigned to treatment conditions consisting of an individualized physical activity intervention delivered by health fitness instructors in community-based exercise facilities or an equal contact wellness control. All participants received standard cognitive behavioral smoking cessation counseling combined with nicotine replacement therapy. The primary outcomes are seven-day point prevalence abstinence at seven weeks, six- and 12 months. Secondary outcomes include self-reported physical activity, dietary intake, body mass index, waist circumference, percent body fat, and nicotine withdrawal symptoms. Participants consist of 392 sedentary smokers (mean [standard deviation] age = 44.6 [10.2] = years; 62% female; 31% African American). Results reported here provide information regarding experiences recruiting smokers willing to change multiple health behaviors including smoking and physical activity.

Physical Exercise in Major Depression: Reducing the Mortality Gap While Improving Clinical Outcomes. Front Psychiatry 2018; 9:762.

Abstract
Major depression shortens life while the effectiveness of frontline treatments remains modest. Exercise has been shown to be effective both in reducing mortality and in treating symptoms of major depression, but it is still underutilized in clinical practice, possibly due to prevalent misperceptions. For instance, a common misperception is that exercise is beneficial for depression mostly because of its positive effects on the body ("from the neck down"), whereas its effectiveness in treating core features of depression ("from the neck up") is underappreciated. Other long-held misperceptions are that patients suffering from depression will not engage in exercise even if physicians prescribe it, and that only vigorous exercise is effective. Lastly, a false assumption is that exercise may be more harmful than beneficial in old age, and therefore should only be recommended to younger patients. This narrative review summarizes relevant literature to address the aforementioned misperceptions and to provide practical recommendations for prescribing exercise to individuals with major depression.

Moderating Effects of Exercise Duration and Intensity in Neuromuscular vs. Endurance Exercise Interventions for the Treatment of Depression: A Meta-Analytical Review. Front Psychiatry 2018; 9:305. [PMID: 30072923 PMCID: PMC6060256 DOI: 10.3389/fpsyt.2018.00305] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Accepted: 06/19/2018] [Indexed: 12/26/2022] Open
Abstract
Background: Exercise training is a beneficial treatment strategy for depression. Previous meta-analytical reviews mainly examined the effect of aerobic exercise on depressive symptoms neglecting comparisons with neuromuscular training and meta-regression considering relevant exercise training prescriptors such as exercise duration, intensity, number of exercise sessions (volume) and frequency. Methods: A structured literature search was conducted in biomedical and psychological databases and study selection was conducted following the PICOS approach. (Randomized) controlled trials that compared supervised neuromuscular or endurance exercise interventions with an inactive control group (CON) in clinically depressed in- or out-patients over 18 years were included. Eligibility and study quality were evaluated by two independent researchers. Standardized mean differences (SMD) for the reduction of depressive symptoms, measured with different evaluation scales (e.g., BDI, HAM-D, PHQ-9, HRSD, MADRS, GDS) were calculated with the adjusted Hedges'g equation as main outcome for the comparison of endurance and neuromuscular exercise interventions vs. CON. Statistical analyses were conducted using a random effects inverse-variance model. Multivariate meta-regression analysis was performed in order to examine the modulating effects of exercise training prescriptors. Results: Twenty seven trials with 1,452 clinically depressed adults were included. 20 out of 27 included trials reached a PEDro score of at least 6, representing high-quality. Irrespective of the exercise mode and study quality, large effects in favor of exercise compared to the control condition were found. Compared to CON, sensitivity analyses revealed a moderate to large effect in favor of endurance exercise [SMD: -0.79 (90% CI: -1.10, -0.48); p < 0.00001, I2 = 84%] and a large effect size in favor of neuromuscular exercise [SMD: -1.14 (90 CI: -1.50, -0.78); p < 0.00001, I2 = 80%]. These effects decreased to moderate for endurance and remained large for neuromuscular trials when considering studies of high quality, indicating a significant difference (p = 0.04). Multivariate meta- regression revealed that exercise duration in endurance trials and exercise intensity in neuromuscular trials had a significantly moderating effect. Conclusions: Strong neuromuscular exercise interventions can be slightly more effective than endurance exercise interventions. Interestingly, exercise duration and exercise intensity moderated the effect size meaningfully. This result might be used on exercise in depression to increase efficacy.

Psychological, pharmacological, and combined smoking cessation interventions for smokers with current depression: A systematic review and meta-analysis. PLoS One 2017; 12:e0188849.

Abstract
We conducted a systematic literature review and meta-analysis (ID: CRD42016051017) of smoking cessation interventions for patients with current depression. We examined the effectiveness of smoking cessation treatments in improving abstinence rates and depressive symptoms. The following electronic databases were used for potentially eligible studies: PUBMED, PSYCINFO, DIALNET and WEB OF KNOWLEDGE. The search terms used were: smoking cessation, depressive disorder, depression, mood, depressive, depressed, smoking, smokers, nicotine, nicotine dependence, and tobacco cigarette smoking. The methodological quality of included studies was assessed using the Effective Public Health Practice Project Quality assessment tool (EPHPP). Of the 6,584 studies identified, 20 were eligible and included in the review. Trial designs of studies were 16 randomized controlled trials and 4 secondary studies. Studies included three types of intervention: psychological (6/30%), pharmacological (6/30%) or combined (8/40%). Four trials comprised special populations of smokers. Four studies received a strong methodological quality, 7 were scored as moderate and 9 studies received a weak methodological rating. Analyses of effectiveness showed that smoking cessation interventions appear to increase short-term and long-term smoking abstinence in individuals with current depression. Subgroup analyses revealed stronger effects among studies that provided pharmacological treatments than in studies using psychological treatments. However, the evidence is weak due to the small number of studies. Smoking abstinence appears to be associated with an improvement in depressive symptoms. Heterogeneity in protocols in similar types of treatment also prevent firm conclusions being drawn on the effectiveness of any particular treatment model to optimally manage abstinence among depressed smokers. Further research is required to strengthen the evidence base.

Abstract
PURPOSE OF REVIEW Exercise is a promising treatment for substance use disorder that may reduce withdrawal symptoms and prevent relapse. In this review, we discuss recent evidence from clinical and preclinical studies for its efficacy, from a behavioral to a molecular level, in order to understand the exercise conditions that lead to beneficial effects. We also highlight the few recent findings of sex-specific differences. RECENT FINDINGS Clinical and preclinical findings show that exercise decreases withdrawal symptoms, including craving, in both males and females. Evidence from clinical studies support the efficacy of exercise to prevent relapse to smoking, although further research is needed to examine sex differences, establish long-term efficacy, and to determine if effects extend to other substance use disorders. Preclinical findings also support the potential utility of exercise to prevent relapse with evidence suggesting that its efficacy is enhanced in males, and mediated by blocking drug-induced adaptations that occur during early abstinence. SUMMARY Sex differences and timing of exercise availability during abstinence should be considered in future studies examining exercise as an intervention for relapse. A better understanding of the neurobiological mechanisms underlying the efficacy of exercise to reduce withdrawal symptoms and prevent relapse is needed to guide its development as a sex-specific treatment.

Abstract
Recent evidence suggests that adolescent and young adult females may be particularly responsive to nicotine use interventions that include exercise or environmental enrichment. This possibility was addressed in the current study by comparing the efficacy of exercise versus non-exercise environmental enrichment (saccharin) during abstinence at reducing subsequent nicotine-seeking/relapse vulnerability in an adolescent-onset rat model. The efficacy of each intervention was examined as a function of estrous cycle phase given findings indicating that hormonal status influences relapse vulnerability and treatment outcome in females. Once adolescent female rats acquired nicotine self-administration, they were given 23-h/day access to nicotine (0.01mg/kg/infusion) for 10days. Following the last self-administration session, rats began a 10-day forced abstinence period with 2-h/day access to an unlocked wheel (exercise, n=15), a bottle containing a saccharin-sweetened solution (0.25%; saccharin, n=19), or without access to a wheel or saccharin (control, n=20). Nicotine-seeking, as assessed under an extinction/cued-induced reinstatement procedure, was examined on day 11 of abstinence. Levels of nicotine-seeking were highest in females tested during estrus as compared to females tested during non-estrus phases. Exercise or saccharin during abstinence reduced nicotine-seeking in females tested during estrus, but neither affected the low levels of nicotine-seeking observed in females tested during non-estrus phases, presumably due to a floor effect. These results demonstrate that exercise or saccharin during abstinence decrease nicotine-seeking, and suggest that either would be effective as an early intervention for nicotine use and addiction in females.

Abstract
OBJECTIVES To assess the benefits and harms of exercise in patients with depression. DESIGN Systematic review DATA SOURCES: Bibliographical databases were searched until 20 June 2017. ELIGIBILITY CRITERIA AND OUTCOMES Eligible trials were randomised clinical trials assessing the effect of exercise in participants diagnosed with depression. Primary outcomes were depression severity, lack of remission and serious adverse events (eg, suicide) assessed at the end of the intervention. Secondary outcomes were quality of life and adverse events such as injuries, as well as assessment of depression severity and lack of remission during follow-up after the intervention. RESULTS Thirty-five trials enrolling 2498 participants were included. The effect of exercise versus control on depression severity was -0.66 standardised mean difference (SMD) (95% CI -0.86 to -0.46; p<0.001; grading of recommendations assessment, development and evaluation (GRADE): very low quality). Restricting this analysis to the four trials that seemed less affected of bias, the effect vanished into -0.11 SMD (-0.41 to 0.18; p=0.45; GRADE: low quality). Exercise decreased the relative risk of no remission to 0.78 (0.68 to 0.90; p<0.001; GRADE: very low quality). Restricting this analysis to the two trials that seemed less affected of bias, the effect vanished into 0.95 (0.74 to 1.23; p=0.78). Trial sequential analysis excluded random error when all trials were analysed, but not if focusing on trials less affected of bias. Subgroup analyses found that trial size and intervention duration were inversely associated with effect size for both depression severity and lack of remission. There was no significant effect of exercise on secondary outcomes. CONCLUSIONS Trials with less risk of bias suggested no antidepressant effects of exercise and there were no significant effects of exercise on quality of life, depression severity or lack of remission during follow-up. Data for serious adverse events and adverse events were scarce not allowing conclusions for these outcomes. SYSTEMATIC REVIEW REGISTRATION The protocol was published in the journal Systematic Reviews: 2015; 4:40.

Abstract
INTRODUCTION Tobacco remains the key modifiable risk factor for the development of a number of diseases, including cardiovascular disease, cerebrovascular disease, lower respiratory infections, chronic obstructive pulmonary disease, tuberculosis and cancer. Among priority populations, smoking prevalence remains high, smokers tend to relapse more often and earlier and fewer are able to sustain quit attempts. This systematic review provides an update on the literature. Areas covered: Twenty-four randomized controlled trials published from 2010-2017, in English language, were identified after searching on Medline, Ovid, Embase and PsycINFO databases. Studies reported on the effectiveness of smoking cessation interventions among six disadvantaged groups known to have high smoking rates: (i) homeless, (ii) prisoners, (iii) indigenous populations, (iv) at-risk youth, (v) people with low income, and (vi) those with a mental illness. Narrative review and assessment of methodological quality of included papers was undertaken. Expert commentary: There is a growing evidence base of methodologically robust studies evaluating a variety of behavioural smoking cessation interventions for priority populations. Multi-component interventions and those examining behavioural interventions incorporating mindfulness training, financial incentives, motivational interviewing and extended telephone-delivered counseling may be effective in the short-term, particularly for smokers on low incomes and people with a mental illness.

Abstract
PROBLEM Depressive symptoms are consistently shown to be related to poor smoking cessation outcomes. Aerobic exercise is a potential treatment augmentation that, given its antidepressant and mood enhancing effect, may bolster cessation outcomes for smokers with elevated depressive symptoms. Lower enjoyment of physical activity may inhibit the acute mood enhancing effects of aerobic exercise. The current study investigated the associations between depressive symptoms, physical activity enjoyment and the acute mood experience from exercise among low-active smokers with elevated depressive symptoms. METHOD Daily smokers with elevated depressive symptoms (N=159; Mage = 45.1, SD = 10.79; 69.8% female) were recruited for a randomized controlled exercise-based smoking cessation trial. Participants self-reported levels of depressive symptoms, physical activity enjoyment, and rated their mood experience (assessed as "mood" and "anxiety") before and after a standardized aerobic exercise test. RESULTS Hierarchical regression analysis revealed that depressive symptom severity accounted for significant unique variance in physical activity enjoyment (R2 =.041, t = -2.61, p = .010), beyond the non-significant effects of gender and level of tobacco dependence. Additionally, physical activity enjoyment was a significant mediator of the association between depressive symptom severity and acute mood experience ("mood" and "anxiety") following the exercise test. CONCLUSIONS Physical activity enjoyment may explain, at least in part, how depressive symptom severity is linked to the acute mood experience following a bout of activity. Interventions that target increasing physical activity enjoyment may ultimately assist in enhancing the mood experience from exercise, and therefore improve smoking cessation likelihood, especially for smokers with elevated depressive symptoms.
