Mood deterioration in response to exercise cessation is well documented, but moderators of this effect remain unknown. This study tested the hypothesis that physically active individuals with higher levels of cognitive vulnerability (i.e., tendencies toward negative thought content and processes in response to stress or negative mood states) are at greater risk for increased anxiety and depressive symptoms when undergoing exercise cessation. Community adults meeting recommended physical activity guidelines (N = 36) participated in a 4-week prospective, longitudinal study with 2 weeks each of maintained exercise and exercise cessation. Cognitive vulnerability measures included dysfunctional attitudes, brooding rumination, and cognitive reactivity (i.e., change in dysfunctional attitudes over a dysphoric mood induction). Anxiety and depression symptoms increased during exercise cessation. Brooding emerged as a risk factor for increases in tension scores on the Profile of Mood States–Brief during exercise cessation. Future studies should explore brooding as a mediator (i.e., potential mechanism) of exercise-induced mood deterioration. [ABSTRACT FROM AUTHOR]

ObjectiveTo describe how young adults use electronic cigarettes (electronic nicotine delivery systems (ENDS)) for smoking cessation and reasons why they may or may not successfully quit smoking.MethodsLongitudinal qualitative data were collected annually from 2017 to 2019 for 25 young adult tobacco users (aged 18-29 years) in California (USA) who used ENDS to quit/reduce smoking. Thematic and trajectory analyses were used to identify key within-person and between-person changes in tobacco/nicotine use over time.ResultsFive types of tobacco use transition were identified among baseline dual users of cigarettes and ENDS: sustained dual use without reduced smoking (n=8), transition to exclusive daily ENDS use (n=6), sustained dual use with reduced smoking (n=5), transition back to exclusive smoking (n=4) and transition to neither smoking nor vaping (n=2). Participants' ENDS use behaviour varied over time in terms of vaping quantity and device characteristics (eg, changing nicotine concentrations/flavours, switching between multiple devices). Three themes that related to successfully replacing cigarettes with ENDS were perceived positive physical effects, perceived satisfaction and enjoyment and context changes. Four themes for unsuccessful replacement were perceived negative physical discomforts, perceived addictiveness and harm, unsatisfactory substitution for cigarettes and device malfunction.ConclusionsYoung adults' experiences with using ENDS as a smoking cessation aid were highly variable. Adequate nicotine delivery and perceived safety and benefits contributed to successfully reducing or quitting cigarettes. Providing behavioural counselling and standardising ENDS products may enhance cessation for young adults.

BACKGROUND: More people who smoke and are living with HIV now die from tobacco-related diseases than HIV itself. Most people are ambivalent about quitting smoking and want to quit someday but not yet. Scalable, effective interventions are needed to motivate and support smoking cessation among people ambivalent about quitting smoking (PAQS) who are living with HIV. OBJECTIVE: This study aims to develop an app-based intervention for PAQS who are living with HIV and assess its feasibility, acceptability, and potential impact. Results of this study will inform plans for future research and development. METHODS: In phase 1, PAQS living with HIV (n=8) participated in user-centered design interviews to inform the final intervention app design and recruitment plan for a subsequent randomized pilot study. In phase 2, PAQS living with HIV were randomized to either a standard care control app or a similar experimental app with additional content tailored for PAQS and those with HIV. Participants were followed for 3 months. Feasibility focused on recruitment, retention, and participants willingness to install the app. The study was not powered for statistical significance. Indices of acceptability (satisfaction and use) and impact (smoking behavior change and treatment uptake) were assessed via automated data and self-report among those who installed and used the app (n=19). RESULTS: Recruitment for both study phases was a challenge, particularly via web-based and social media platforms. Enrollment success was greater among people living with HIV recruited from a health care provider and research registry. Once enrolled, retention for the phase 2 randomized study was good; 74% (14/19) of the participants completed the 3-month follow-up. Phase 1 findings suggested that PAQS living with HIV were receptive to using an app-based intervention to help them decide whether, when, and how to stop smoking, despite not being ready to quit smoking. Phase 2 findings further supported this conclusion based on feedback from people who agreed to use an app, but group differences were observed. Indices of acceptability favored the experimental arm, including a descriptively higher mean number of sessions and utilization badges. Similarly, indices of potential impact were descriptively higher in the experimental arm (proportion reducing smoking, making a quit attempt, or calling free tobacco quitline). No participants in either arm quit smoking at the 3-month follow-up. CONCLUSIONS: On the basis of this formative work, PAQS living with HIV may be receptive to using a mobile health-based app intervention to help them decide whether, when, or how to stop using tobacco. Indices of acceptability and impact indicate that additional research and development are warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT05339659; https://clinicaltrials.gov/study/NCT05339659.

BACKGROUND: Reducing cigarette addictiveness has the potential to avert millions of yearly tobacco-related deaths worldwide. Substantially reducing nicotine in cigarettes decreases cigarette consumption, but no large clinical trial has determined the effects of reduced-nicotine cigarettes when other nicotine-containing products are available. The aim of this study was to examine the effects of reduced-nicotine cigarettes in the context of the availability of alternative nicotine delivery systems. METHODS: In a U.S. six-site, open-label, parallel-arm study, smokers were randomized for twelve weeks to an experimental marketplace containing cigarettes with either 0.4 mg or 15.8 mg nicotine per gram of tobacco; all had access to non-combusted alternative nicotine delivery systems (e.g., e-cigarettes; medicinal nicotine). Group differences in the primary outcomes (cigarettes per day, number of smoke-free days) were examined using linear and negative binomial regression, respectively (Trial Registration: NCT03272685). FINDINGS: Among 438 randomized participants (mean [standard deviation (SD), range] age, 44.5 [11.9, 20-73] years, 225 [51.4%] women, 282 [64.4%] White and 339 [77.4%] trial completers), those in the 0.4 mg vs. 15.8 mg nicotine cigarette condition experienced significantly lower cigarettes per day at the end of intervention (mean [SD], 7.05 [7.88] vs. 12.95 [9.07], adjusted mean difference, -6.21 [95% CI, -7.66 to -4.75], P

BackgroundSmoking rates among people living with behavioral health conditions (BHC) range from 30 to 65% and are 2-4 times higher than rates found in the general population. Starting tobacco treatment during a hospital stay is effective for smoking cessation, but little is known regarding treatment response among inpatients with BHC.ObjectiveThis study pooled data across multiple clinical trials to determine the relative success in quitting among participants with BHC compared to other study participants.ParticipantsAdults who smoke (≥ 18 years old) from five hospital-based smoking cessation randomized clinical trials.DesignA retrospective analysis using data from the electronic health record to identify participants with primary diagnoses related to BHC. Recruitment and data analysis were conducted from 2011 to 2016. We used propensity score matching to pair patients with BHC to those with similar characteristics and logistic regression to determine differences between groups.MeasuresThe main outcome was self-reported 30-day abstinence 6 months post-discharge.ResultsOf 6612 participants, 798 patients had a BHC-related primary diagnosis. The matched sample included 642 pairs. Nearly 1 in 3 reported using tobacco medications after hospitalization, with no significant difference between patients with and without BHC (29.3% vs. 31.5%; OR (95% CI) = 0.90 (0.71, 1.14), p = 0.40). Nearly 1 in 5 patients with BHC reported abstinence at 6 months; however, their odds of abstinence were 30% lower than among people without BHC (OR (95% CI) = 0.70 (0.53,0.92), p = 0.01).ConclusionWhen offered tobacco treatment, hospitalized patients with BHC were as likely as people without BHC to accept and engage in treatment. However, patients with BHC were less likely to report abstinence compared to those without BHC. Hospitals are a feasible and promising venue for tobacco treatment among inpatients with BHC. More studies are needed to identify treatment approaches that help people with BHC achieve long-term abstinence.

BACKGROUND: Combining smoking with poor eating habits significantly elevates the risk of chronic illnesses and early death. Understanding of how dietary quality shifts post-smoking cessation remains limited. The objective of this study is to examine dietary quality - using Healthy Eating Index (HEI - 2020) and its 13 components, among current, former, and never smokers, and particularly the impact of quitting and the duration of cessation on dietary habits. METHODS: A cross-sectional analysis of 31,569 adults from the National Health and Nutrition Examination Survey (NHANES) 2005-2018 was conducted. Dietary quality was assessed using HEI-2020 scores, which were determined by NIH developed - simple HEI scoring algorithm per person. Smoking status was categorized into current, former, and never smokers, with further subdivisions for current (heavy/light smokers) and former smokers (duration post-cessation). Descriptive analysis and multiple regression models weighted to represent the US population were performed. RESULTS: The current smoking rate was 19.4%, with a higher prevalence in males (22.5%) than females (17.5%). Current smokers reported statistically significantly lower HEI total score than both former and never smokers. Former smokers exhibited HEI scores similar to those of never smokers. The adjusted HEI total scores for current, former, and never smokers were 49.2, 54.0, and 53.3, respectively, with a statistically significant difference (p  0.05, respectively). Compared to current smokers, former smokers tended to consume more beneficial foods (e.g., fruits, vegetables, greens and beans, whole grains, proteins, and fatty acids), while also consuming more sodium and less added sugar. CONCLUSIONS: Current smokers, particularly heavy smokers, exhibit poorer dietary habits than former and never smokers. The dietary quality of former smokers aligns with never smokers over time, highlighting the positive impact of smoking cessation on diet. This has implications for reducing chronic disease risks associated with poor diet and smoking.

UNLABELLED: Continuous tobacco use in patients with cancer is linked to substantial healthcare costs due to increased risks and complications, whereas quitting smoking leads to improved treatment outcomes and cost reductions. Addressing the need for empirical evidence on the economic impact of smoking cessation, this study examined the association between smoking cessation and healthcare cost utilization among a sample of 930 patients with cancer treated at The University of Texas MD Anderson Cancer Centers Tobacco Research and Treatment Program (TRTP). Applying conditional quantile regression and propensity scores to address confounding, our findings revealed that abstinence achieved through the TRTP significantly reduced the median cost during a 3-month period post-quitting by $1,095 [β = -$1,095, P = 0.007, 95% confidence interval (CI), = (-$1,886 to -$304)]. Sensitivity analysis corroborated these conclusions, showing a pronounced cost reduction when outlier data were excluded. The long-term accrued cost savings from smoking cessation could potentially offset the cost of participation in the TRTP program, underscoring its cost effectiveness. An important implication of this study is that by reducing smoking rates, healthcare systems can more efficiently allocate resources, enhance patient health outcomes, and lessen the overall cancer burden. PREVENTION RELEVANCE: This study emphasizes the dual impact of smoking cessation programs in patients with cancer: quitting smoking and reducing healthcare costs. It highlights the importance of integrating cessation programs into cancer prevention strategies, ensuring both individual health benefits and broader, system-wide economic efficiencies.

AimsTo examine the relationship between changes in electronic cigarette (e-cigarette) use and subsequent cigarette smoking cessation.MethodsUsing data from the Population Assessment of Tobacco and Health Study (wave 1-wave 4), we analysed a study cohort of 3014 current adult cigarette smokers at wave 1 who tried to quit during the past 12 months. We categorised changes in e-cigarette use from wave 1 to wave 2 as: daily initiation, non-daily initiation, increase to daily use, increase to non-daily use, stable daily use, stable non-daily use, decrease from daily use, quit non-daily use and non-use. We estimated multivariable logistic regressions on short-term (≥1 month and

BACKGROUND: While much progress has been made in reducing tobacco use in many countries, both active and passive smoking remain challenges. The benefits of smoking cessation are universally recognized, and the hospital setting is an ideal setting where smokers can access smoking cessation services as hospital admission can be a cue to action. Consistent delivery of good quality smoking cessation care across health services is an important focus for reducing the harm of tobacco use, especially among continued smokers. AIMS: Our objective was to document the smoking cessation medication and support services provided by specialist adult cancer hospitals across Ireland, a country with a stated tobacco endgame goal. METHODS: A cross-sectional survey based on recent national clinical guidelines was used to determine smoking cessation care delivery across eight specialist adult cancer tertiary referral university hospitals and one specialist radiotherapy center. Survey responses were collected using Qualtrics, a secure online survey software tool. The data was grouped, anonymized, and analyzed in Microsoft Excel. RESULTS: All responding hospitals demonstrated either some level of smoking cessation information or a service available to patients. However, there is substantial variation in the type and level of smoking cessation information offered, making access to smoking cessation services inconsistent and inequitable. CONCLUSION: The recently launched National Clinical Guideline for smoking cessation provides the template for all hospitals to ensure health services are in a position to contribute to Irelands tobacco endgame goal.

Cigarette smoking remains a leading cause of preventable disease and death worldwide. Due to the devastating negative health effects of smoking, many users attempt to quit, but few are successful in the long-term. Thus, there is a critical need for novel therapeutic approaches. In these investigations, we sought to examine whether cannabidiol (CBD) has the potential to be repurposed as a nicotine cessation therapeutic. In the first study, male and female mice were trained to respond for intravenous nicotine infusions at either a low or moderate nicotine dose and then were pretreated with CBD prior to their drug-taking session. We found that CBD produced a significant decrease in the number of nicotine rewards earned, and this effect was evidenced across CBD doses and with both the low and moderate levels of nicotine intake. These effects on drug intake were not due to general motor-related effects, since mice self-administering food pellets did not alter their behavior with CBD administration. The potential effects of CBD in mitigating nicotine withdrawal symptoms were then investigated. We found that CBD attenuated the somatic signs of nicotine withdrawal and prevented nicotine's hyperalgesia-inducing effects. Taken together, these results demonstrate that modulation of cannabinoid signaling may be a viable therapeutic option as a smoking cessation aid.

BACKGROUND: Approximately 70-80% of people experiencing homelessness in the United States use tobacco. Smoking cessation programs specifically for this population have been found to be less effective for African American participants. The purpose of this study was to explore discrimination experiences and their impact on smoking habits and readiness to quit cigarette smoking while experiencing homelessness. METHODS: In the qualitative phase of this mixed methods study, five focus groups were conducted for African Americans residing in a homeless shelter in Skid Row, Los Angeles, CA. Using a semi-structured interview guide, we asked participants about discrimination experiences, how smoking habits were impacted by these experiences, and tools needed to successfully abstain from cigarette smoking. Qualitative descriptive content analysis was used to explore discrimination experiences and its association with readiness to quit cigarette smoking. RESULTS: Of the 17 participants, 14 (82.4%) were male, and the average age was 46.8 years. Using a qualitative In Vivo coding method, three themes were revealed: Experiencing Discrimination while Black, The Psychosocial Fabric-Why Quitting Cigarette Smoking is a Challenge, and The Lesser of Two Evils-Choosing to Smoke over More Harmful Options. Participants discussed working in the blue-collar workforce while Black, identifying as a double minority, smoking to cope with stress, early exposure to cigarettes, smoking being a central part of ones belonging to a group, and the legality of cigarette smoking. DISCUSSION: Our findings show that African Americans experiencing homelessness (1) may experience discrimination in multiple settings, regardless of housing status, (2) could have grown up around cigarette smoking and remain surrounded by it while experiencing homelessness, and (3) may experience a calming effect with smoking, which slows some from reacting negatively to adverse situations. CONCLUSION: Barriers to successfully abstaining from smoking are multifactorial among African Americans experiencing homelessness and should be addressed individually. Future research should explore the cultural tailoring of interventions that support cessation efforts unique to minoritized populations to improve smoking cessation programs offered to this population.

Smoking is common among adults of all ages. Decades of research have shown that smoking is linked to side effects such as lung cancer. This study aims to systematically review how smoking is linked to sleep. Database searches were done through Web of Science and Google Scholar. A total of 19 peer-reviewed journals were referenced to conduct this literature review. 15 peer-reviewed journals were used for the results. Results demonstrated that smoking was found to be correlated with sleep deprivation in both males and females of all ages. Environmental Tobacco Smoke (ETS) was a source of non-smokers' sleep complaints. Although there are multiple kinds of cigarettes, sleep quality has been shown to be poor regardless of the smoking medium. Ceasing smoking may lead to sleep benefits. Additional research will need to be conducted to further corroborate this statement.

Adults social network ties serve multiple functions and play prominently in quitting smoking. We examined three types of adults egocentric social networks, including family, friends, and friends online to investigate how two network characteristics with major relevance to health behavior, network size and tie closeness, related to the emotional and confidant support and to pro- and anti-smoking social influence these ties may transmit. We also examine whether the social support and social influence constructs related to smoking abstinence. We utilized baseline and 7-day abstinence survey data from 123 adult current smokers attempting to quit prior to the start of a randomized controlled quit-smoking trial of a social support intervention for quitting smoking on Twitter. To examine study relationships, we estimated Negative Binomial Regression models and Logistic Regression models. For all networks, network size and tie closeness related positively to most of the social support and social influence constructs, with tie closeness related most strongly, especially for online friends. Family pro-smoking social influence related negatively to smoking abstinence, and there were marginally negative relationships for family emotional support and family confidant support. Online friend emotional support had a marginally positive relationship with smoking abstinence. Overall, our findings indicated the importance of the social support and social influence functions of each type of network tie, with larger networks and closer ties related to higher levels of social support and social influence. Moreover, family network pro-smoking social influence may compromise abstinence while emotional support from online friend network ties may reinforce it.

IntroductionLesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) individuals use tobacco at disproportionately high rates but are as likely as straight tobacco users to want to quit and to use quitlines. Little is known about the demographics and geographic distribution of LGBTQ quitline participants, their engagement with services, or their long-term outcomes.Aims and methodsCalifornians (N = 333 429) who enrolled in a statewide quitline 2010-2022 were asked about their sexual and gender minority (SGM) status and other baseline characteristics. All were offered telephone counseling. A subset (n = 19 431) was followed up at seven months. Data were analyzed in 2023 by SGM status (LGBTQ vs. straight) and county type (rural vs. urban).ResultsOverall, 7.0% of participants were LGBTQ, including 7.4% and 5.4% of urban and rural participants, respectively. LGBTQ participants were younger than straight participants but had similar cigarette consumption. Fewer LGBTQ participants reported a physical health condition (42.1% vs. 48.4%) but more reported a behavioral health condition (71.1% vs. 54.5%; both p's < .001). Among both LGBTQ and straight participants, nearly 9 in 10 chose counseling and both groups completed nearly three sessions on average. The groups had equivalent 30-day abstinence rates (24.5% vs. 23.2%; p = .263). Similar patterns were seen in urban and rural subgroups.ConclusionsLGBTQ tobacco users engaged with and appeared to benefit from a statewide quitline even though it was not LGBTQ community-based. A quitline with staff trained in LGBTQ cultural competence can help address the high prevalence of tobacco use in the LGBTQ community and reach members wherever they live.ImplicationsThis study describes how participants of a statewide tobacco quitline broke down by sexual orientation and gender. It compares participants both by SGM status and by type of county to provide a more complete picture of quitline participation both in urban areas where LGBTQ community-based cessation programs may exist and in rural areas where they generally do not. To our knowledge, it is the first study to compare LGBTQ and straight participants on their use of quitline services and quitting aids, satisfaction with services received, and rates of attempting quitting and achieving prolonged abstinence from smoking.

Bupropion is an atypical antidepressant indicated for the treatment of major depressive disorder (MDD), seasonal affective disorder (SAD), and smoking cessation. It is also used off‐label for attention deficit hyperactivity disorder (ADHD). Its mechanism of action includes the selective norepinephrine and dopamine reuptake inhibitor (NDRI). The drug is available in immediate‐release (IR), sustained‐release (SR), and extended‐release (XL) formulations. Common side effects are typically mild and include anxiety, insomnia, headache, dizziness, constipation, and nausea. Rarely, cutaneous hypersensitivity reactions may occur. We describe a 23‐year‐old man who developed severe and diffuse urticaria and angioedema 4 weeks after initiation of bupropion XL for MDD and ADHD. The bupropion was stopped, and he was treated with levocetirizine, diphenhydramine (oral and topical), and methylprednisolone with complete resolution of his symptoms within 2 weeks. Due to a good initial therapeutic response to the medication, a trial of bupropion SR was initiated. The patient again had a favorable therapeutic response without any dermatologic side effects.

Rationale: While tobacco industry data suggests that switching from combustible cigarettes to heated tobacco products (HTPs), like IQOS, may reduce the users' exposure to respiratory toxicants, it is not known if using HTPs impacts the outcomes of acute respiratory infections. Objectives: Does switching from cigarettes to HTPs improve responses to pulmonary infection. Methods: We conducted experiments in which 3 groups of mice were pre-exposed to cigarette smoke for 8 weeks, followed by 8-week exposure to (1) HTPs (tobacco product switching), (2) air (smoking cessation), or (3) continued exposure to cigarette smoke. Pulmonary bacterial clearance and surrogate markers of lung damage were assessed as study outcomes. Main results: Significantly compromised clearance of bacteria from the lungs post-acute challenge occurred in both the switching group and in mice continuously exposed to cigarette smoke. Bacterial clearance, inflammatory T-cell infiltration into the lungs, and albumin leak improved at 12 h post-acute challenge in the switching group compared to mice continuously exposed to cigarette smoke. Bacterial clearance, total lung immune-cell infiltration, inflammatory T-cell infiltration into the lungs, the content of total proteins in the BAL, and albumin leak measured post-acute challenge were compromised in the switching group compared to mice in the cessation group. Switching from cigarettes to HTPs did not improve lung myeloperoxidase and neutrophil elastase levels (markers for lung inflammation and damage), which, however, were significantly reduced in the cessation group. Conclusions: This study reveals only a modest improvement in respiratory infection outcomes after switching exposure from cigarettes to HTPs and significantly compromised outcomes compared to a complete cessation of exposure to all tobacco products.

Introduction: Mood-tailored communications may help increase the effectiveness of smoking cessation messaging interventions. We used both self-report and psychophysiological measures to test the impact of mood on responses to cessation messages in adults who smoke. Methods: In a two-part (crowdsourcing and psychophysiological studies) study, the impact of 30 smoking cessation messages comprised of five themes (i.e., financial, health, quality-of-life, challenges in quitting, motivation to quit) were tested. In a crowdsourcing study, participants (N = 600) were randomly placed into one of three mood induction tasks (i.e., positive, negative, neutral), and then viewed the smoking cessation messages. After each message, they were asked to self-report their motivation to quit, message receptivity, and the perceived relevance of the messages. In an in-lab, psychophysiological study, participants (N = 42) completed the same tasks as the crowdsourcing participants but were monitored for heart rate, skin conductance, and eye-tracking while viewing the cessation messages. Using a multi-attribute decision-making model (MADM) using outcomes from both studies, messages were ranked for each mood state. Results: The top messages for participants in the positive mood condition included the challenges in quitting, financial costs/rewards, and motivations to quit themes. The top messages for participants assigned to the negative mood condition included the challenges in quitting, quality-of-life, and financial costs/rewards themes. For participants in the neutral mood condition, messages in the challenges in quitting and quality of life themes performed best. Conclusions: Variations in the preferences of messages and themes by mood condition suggest that mood-tailored communication may increase the effectiveness of smoking cessation messages.

Background: DNA methylation profiling may provide a more accurate measure of the smoking status than self-report and may be useful in guiding clinical interventions and forensic investigations. In the current study, blood DNA methylation profiles of nearly 800 Polish individuals were assayed using Illuminia EPIC and the inference of smoking from epigenetic data was explored. In addition, we focused on the role of the AHRR gene as a top marker for smoking and investigated its responsiveness to other lifestyle behaviors. Results: We found > 450 significant CpGs associated with cigarette consumption, and overrepresented in various biological functions including cell communication, response to stress, blood vessel development, cell death, and atherosclerosis. The model consisting of cg05575921 in AHRR (p = 4.5 × 10–32) and three additional CpGs (cg09594361, cg21322436 in CNTNAP2 and cg09842685) was able to predict smoking status with a high accuracy of AUC = 0.8 in the test set. Importantly, a gradual increase in the probability of smoking was observed, starting from occasional smokers to regular heavy smokers. Furthermore, former smokers displayed the intermediate DNA methylation profiles compared to current and never smokers, and thus our results indicate the potential reversibility of DNA methylation after smoking cessation. The AHRR played a key role in a predictive analysis, explaining 21.5% of the variation in smoking. In addition, the AHRR methylation was analyzed for association with other modifiable lifestyle factors, and showed significance for sleep and physical activity. We also showed that the epigenetic score for smoking was significantly correlated with most of the epigenetic clocks tested, except for two first-generation clocks. Conclusions: Our study suggests that a more rapid return to never-smoker methylation levels after smoking cessation may be achievable in people who change their lifestyle in terms of physical activity and sleep duration. As cigarette smoking has been implicated in the literature as a leading cause of epigenetic aging and AHRR appears to be modifiable by multiple exogenous factors, it emerges as a promising target for intervention and investment.

Rationale Aims and Objectives Method Results Conclusion Individuals waiting for total‐knee‐replacement surgery are at risk of developing morbidities and frailty which may affect their postoperative recovery. Multi‐modal prehabilitation could mitigate these unintentional effects.To implement and evaluate a specified online multi‐modal prehabilitation intervention in patients waiting for total‐knee‐replacement surgery in a large urban acute hospital trust.A non‐randomised, pre/post analysis implementation pilot with a nested qualitative study was conducted and is reported following the standards for implementation studies (StaRI) guidance. Of 35 listed cases, 12 (34%) were eligible, recruited, and completed an 8‐week multi‐modal online intervention incorporating 5 modalities (i) cardiovascular exercise, (ii) strength/balance function, (iii) smoking cessation, (iv) opioid use, (v) nutritional intake. Interventions were specified using the Rehabilitation Treatment Specification System, where rehabilitation treatment theory accounts for discrete treatment components. Two participated in an online qualitative interview post‐intervention. Process evaluation included intervention fidelity, eligibility/recruitment/retention rates, and clinical outcomes included knee function, frailty, gait velocity, anxiety/depression, and quality of life.Five participants (42%) completed the intervention and were retained at follow‐up. The intervention was delivered online at specified doses, frequency/durations indicative of high respective adherence, quantity, and exposure fidelity.There was significant improvement in median oxford knee score (p = 0.015), gait velocity (p = 0.040) and anxiety (p = 0.023). The interview revealed 5 themes; surgery preconceptions, motivation, acceptability, postoperative experiences, and future recommendations confirming acceptance of the intervention by virtue of adhering to the treatment exposure delivered as planned.The specified multi‐modal prehabilitation was acceptable, implementable, and demonstrated evidence of preliminary efficacy. Further experimental pilot work that represents the spectrum of frailty, obesity, quality of life, and comorbidities associated with total‐knee‐replacement surgery is indicated.

The availability of well-established analytical methods is crucial to cope with the fast-ongoing research for the development of new drug delivery formulations. In this work, a rapid highly green chromatographic method was developed for the simultaneous determination of nicotine (NIC) and caffeine (CAF) to be applied for an in-vitro release study from a newly prepared quick mist mouth spray co-formula (QMS), as a complementary synergistic fast-onset relief of cravings during smoking cessation. The chromatographic resolution was accomplished on a cyano column using isocratically delivered (1.0 mL/ min) glycerol: orthophosphoric acid (OPA) (0.2 M) adjusted to pH 3.0 using 0.05 M triethylamine (5:95, v/v) and UV detection at 260 nm. Well resolved peaks of NIC and CAF were eluted at 2.1 and 3.9 min (Rs = 5.64), with linear responses between 0.1 and 20.0 µg/mL and 0.2–40.0 µg/mL, and detection limits of 0.03 and 0.07 µg/mL for NIC and CAF, respectively. The developed method showed good analytical performance (accuracy, precision, robustness, and selectivity) as well as superiority in practicality and ecological profile compared to reported methods applying GAPI, analytical eco-scale, AGREE, BAGI, and whiteness metric tool. The developed method was successfully applied for NIC and CAF determination in their pharmaceutical preparations, and artificial saliva with no significant differences from reported method results (F-test and t-test). Moreover, an in-vitro release study of NIC and CAF from QMS was performed employing the developed method that revealed diffusion-controlled release, compared to mixed diffusion/ polymer chain relaxation for marketed single component formulation, showing the superiority of QMS in reducing drug level fluctuations of NIC and CAF and improving their bioavailability.

In this paper, we introduce an age-structured quit-smoking model that incorporates the duration of smoking cessation, a crucial parameter related to smoking cessation counseling and disease treatment. We identify the threshold value R0, which determines the existence and stability of the smoking-free steady state. Our findings show that the smoking-free steady state is locally and globally stable if R0 < 1, whereas it becomes unstable, and the unique steady state with present smokers emerges and is locally and globally stable if R0 > 1. We propose an optimal control strategy, and our results show its ability to effectively decrease the number of smokers and promote smoking cessation. To validate our findings and to study the influence of varying parameters on the model’s dynamics, numerical simulations are carried out. A concise conclusion is then shared at the end of the paper.

Background: Homeless-experienced adults smoke at rates 5 times that of the general adult population, and often have limited access to cessation treatments while homeless. Permanent Supportive Housing (PSH) can be a catalyst for cessation treatment utilization, yet little is known about use of these treatments following PSH entry, or how to tailor and implement cessation care that meets homeless-experienced adults' vulnerabilities. Methods: Using Department of Veterans Affairs (VA) administrative data, we assessed smoking status (ie, current, former, non/never) among a cohort of homeless-experienced Veterans (HEVs) housed in Los Angeles-based PSH. We compared cessation treatment use rates (ie, nicotine replacement therapies, cessation medications, psychosocial counseling) pre- and post-housing using Chi-square tests. Predisposing (ie, demographics), enabling (eg, primary care, benefits), and need characteristics (ie, health, mental health, substance use diagnoses) were examined as correlates of cessation treatment utilization pre- and post-housing in univariable and multivariable logistic regression models. Results: Across HEVs (N = 2933), 48.6% were identified as currently-smoking, 17.7% as formerly-smoking, and 14.0% as non/never smoking. Among currently- and formerly-smoking HEVs (n = 1944), rates of cessation treatment use post-housing were significantly lower, compared to pre-housing, across all treatment types. Health, mental health, and substance use was more prevalent among currently- and formerly-smoking HEVs compared to non/never-smoking HEVs, and most diagnoses were positively associated with utilization univariably. However, in multivariable models, cessation clinic referrals and primary care engagement were the only significant (P <.001) predictors of pre-housing and post-housing cessation treatment utilization. Conclusion: Among HEVs, we found high smoking rates and low cessation treatment utilization pre- and post-PSH entry. Efforts to educate providers about this population's desire to quit smoking, support primary care engagement, and increase cessation clinic referrals may bolster their utilization. For homeless-experienced adults, optimizing cessation treatment accessibility by embedding cessation services within PSH and homeless service settings may reduce utilization impediments.

Background: Maternal preconception and pregnancy exposures have been linked to offspring adiposity. We aimed to quantify the effect of changes in maternal weight and smoking status between pregnancies on childhood overweight/obesity (≥ 85th centile) and obesity (≥ 95th centile) rates in second children. Methods: Records for 5612 women were drawn from a population-based cohort of routinely collected antenatal healthcare records (2003–2014) linked to measured child body mass index (BMI) age 4–5 years. We applied the parametric G-formula to estimate the effect of hypothetical changes between pregnancy-1 and pregnancy-2 compared to the natural course scenario (without change) on child-2 BMI. Results: Observed overweight/obesity and obesity in child-2 at age 4–5 years were 22.2% and 8·5%, respectively. We estimated that if all mothers started pregnancy-2 with BMI 18·5–24·9 kg/m² and all smokers stopped smoking, then child-2 overweight/obesity and obesity natural course estimates of 22.3% (95% CI 21.2–23.5) and 8·3% (7·6–9·1), would be reduced to 18.5% (17.4–19.9) and 6.2% (5.5–7.0), respectively. For mothers who started pregnancy-1 with BMI 18·5–24·9 kg/m², if all smokers stopped smoking, child-2 overweight/obesity and obesity natural course estimates of 17.3% (16.0–18.6) and 5·9% (5·0–6·7) would be reduced to 16.0% (14.6–17.3) and 4·9% (4·1–5·7), respectively. For mothers who started pregnancy-1 with BMI ≥30 kg/m², if BMI was 18·5–24·9 kg/m² prior to pregnancy-2, child-2 overweight/obesity and obesity natural course estimates of 38.6% (34.7–42.3) and 17·7% (15·1–20·9) would be reduced to 31.3% (23.8–40.0) and 12.5 (8.3–17.4), respectively. If BMI was 25.0–29.9 kg/m² prior to pregnancy-2, these estimates would be 34.5% (29.4–40.4) and 14.6% (11.2–17.8), respectively. Conclusion: Interventions supporting women to lose/maintain weight and quit smoking between pregnancies could help reduce rates of overweight/obesity and obesity in second children. The most effective interventions may vary by maternal BMI prior to the first pregnancy. [ABSTRACT FROM AUTHOR]

Introduction Methods Results Discussion and Conclusions Most patients receiving opioid agonist treatment (OAT) smoke tobacco. Approved cessation interventions are less effective in this group than the wider population. We investigated how people on OAT experience nicotine vaping to quit smoking.Patients on OAT randomised to the vaping arm of a smoking cessation trial were invited to participate in structured interviews incorporating broad pre‐determined themes. A qualitative descriptive approach employing template analysis was used. Four authors coded transcripts, discussed discrepancies, modified the template using both inductive and deductive approaches. Authors made explicit their starting orientations and independent authors sought disconfirmatory data in a subsequent round of analysis.Four women and eight men (median age 44 years) participated, including four who identified as Aboriginal. Participants reported vaping as cheaper, more acceptable and less stigmatising than smoking but expressed concerns about ongoing accessibility due to the Australian prescription access model. Some found it technically challenging at first, but not more so than standard nicotine replacement therapies. Participants gave accounts of craving and withdrawal experiences, including supplementary use of nicotine patches, and compulsions to vape frequently and intensely, potentially indicating need for higher nicotine dosage. Participants generally reported that vaping helped them quit smoking, though some worried about swapping nicotine addictions. Others were glad to be using a lower‐risk alternative.This group reported varied experiences of nicotine vaping but were mainly optimistic that it could help them and others quit smoking. This was despite initial nicotine cravings and concerns about remaining addicted long‐term. [ABSTRACT FROM AUTHOR]

Purpose Material and Method Findings Conclusion This study aims to examine the effect of online individual motivational interviewing based on the transtheoretical model on pregnant women's smoking cessation behaviour.Sixty‐two pregnant women who did not complete the 16th gestational week and who smoked were randomly assigned to intervention (n = 31) and control (n = 31) groups. While the intervention group was administered model‐based motivational individual counselling interventions, the control group was administered no interventions.The results showed that 58.1% of the pregnant women in the intervention group and 22.6% of the pregnant women in the control group ceased smoking.Online motivational interviewing based on the transtheoretical model was found to be effective in pregnant women's smoking cessation.

Background: Tobacco smoking rates are higher in rural, regional, and remote (RRR) areas in Australia, and strategies to improve access to quit supports are required. This pilot study examined the feasibility of a smoking cessation intervention for people in RRR areas who smoke with the intention of using this data to design a powered effectiveness trial. Methods: A randomised controlled trial (RCT) of the feasibility of a 12‐week 'Outback Quit Pack' intervention consisting of mailout combination nicotine replacement therapy (NRT) and a proactive referral to Quitline, compared with a minimal support control (1‐page smoking cessation support information mailout) was conducted between January and October 2021. Participants recruited via mailed invitation or Facebook advertising, were adults who smoked tobacco (≥10 cigarettes/day) and resided in RRR areas of New South Wales, Australia. Participants completed baseline and 12‐week follow‐up telephone surveys. Outcomes were feasibility of trial procedures (recruitment method; retention; biochemical verification) and acceptability of intervention (engagement with Quitline; uptake and use of NRT). Results: Facebook advertising accounted for 97% of participant expressions of interest in the study (N = 100). Retention was similarly high among intervention (39/51) and control (36/49) participants. The intervention was highly acceptable: 80% of the intervention group had ≥1 completed call with Quitline, whilst Quitline made 3.7 outbound calls/participant (mean 14:05 mins duration). Most of the intervention group requested NRT refills (78%). No differences between groups in self‐reported cessation outcomes. Biochemical verification using expired air breath testing was not feasible in this study. Conclusion: The Outback Quit Pack intervention was feasible and acceptable. Alternative methods for remote biochemical verification need further study. So What?: A powered RCT to test the effectiveness of the intervention to improve access to evidence‐based smoking cessation support to people residing in RRR areas is warranted.

The effectiveness of mutual help groups (MHGs) in promoting addiction recovery has been widely acknowledged. However, the psychological mechanisms underlying the impact of MHGs remain somewhat uncertain. Drawing on a social identity perspective, this study investigated a sequential mediation model in which social support is posited as a driving factor that enhances abstinence maintenance through group identification, recovery identity, and self‐efficacy. A sample of 820 smokers, participating in a 6‐month collective smoking cessation programme which included access to an online help group, completed measures of social support, group identification, smoker/ex‐smoker identity, and self‐efficacy at the programme's outset. Smoking abstinence was assessed 6 and 9 months later. The findings supported the proposed model, indicating that social support was positively associated with MHG identification, which, in turn, was related to a stronger recovery identity. Subsequently, recovery identity was associated with increased self‐efficacy, and indirectly, with smoking abstinence at both measurement times. Additional analyses testing alternative mediation models further supported the validity of the proposed model. These findings suggest that social identity factors play significant roles in accounting for the effectiveness of MHGs for addiction recovery. [ABSTRACT FROM AUTHOR]

Background—Gastroesophageal reflux disease (GERD) is commonly diagnosed in patients with severe obesity. The outcomes of patients with preoperative GERD after sleeve gastrectomy (SG) are unclear, and some surgeons consider GERD a contraindication for SG. Methods—A retrospective analysis of a tertiary university hospital database was conducted. All patients with preoperative GERD undergoing SG between January 2012 and January 2020 and having at least two years of follow-up were included in the analysis. A validated GERD-associated quality of life questionnaire (GERD-HRQL) was completed by all patients. Results—During the study period, 116/1985 patients (5.8%) were diagnosed with GERD before SG. In total, 55 patients were available for a two-year follow-up and were included in the analysis. Median follow-up was 40 months (range 24–156 months). Mean total weight loss (TWL) was 24.0% ± 12.0%. On follow-up, 43 patients (78.1%) reported having GERD symptoms. In patients who underwent postoperative endoscopy, less than a third had esophagitis. The mean GERD-HRQL score was 25.2 ± 10.9. On univariable analysis, patients with poor GERD-HRQL had lower BMI at baseline (41.5 ± 12.4 vs. 44.9 ± 10.0 kg/m2, p = 0.03), were less commonly smokers at baseline (8.1% vs. 33.3%, p = 0.02), and had lower TWL at the end of the follow-up (22.2% ± 10.4% vs. 28.9% ± 13.7%, p = 0.05). On multivariable analysis, smoking status at baseline and TWL at last follow-up were independent predictors of better GERD-HRQL. Conclusions—In conclusion, most GERD patients after SG have a relatively high GERD-HRQL score, most patients still have GERD symptoms during the follow-up, and approximately a third of patients have endoscopic signs of esophagitis. There was an association between patients with higher TWL and smoking at baseline and better GERD-HRQL outcomes. The latter is potentially due to smoking cessation. [ABSTRACT FROM AUTHOR]

Low birth weight (LBW) is a global health issue. We conducted a cross-sectional study to assess factors associated with LBW at Georgetown Public Hospital Corporation (GPHC). We used data from all women who delivered a single live baby as of 28 weeks of gestational age from July to September 2022. 1,304 mothers and their respective live-born babies were included. Logistic regression was used to identify LBW-associated factors at p <.05. The prevalence of LBW was 13.3 percent (95 percent IC: [11.6–15.3]). Women who were primigravida (AOR: 2.18, 95 percent CI = [1.40–3.38]), smoked during pregnancy (AOR: 3.41, 95 percent CI: [1.05–11.03]), had fewer than eight antenatal care visits (AOR: 2.43, 95 percent CI = [1.54–3.83]) were significantly associated with LBW. Similarly, those who had gestational hypertension (AOR: 2.30, 95 percent CI = [1.36–3.80]), urinary tract infections during pregnancy (AOR: 2.91, 95 percent CI = [1.22–2.97]), and gave birth before 37 weeks of gestational age (AOR: 22.65, 95 percent CI = [14.32–35.83]) were more likely to have their babies born with LBW. These findings are crucial for guiding health policies to improve prenatal care access, provide smoking cessation programs, control gestational hypertension, and prioritize early detection and treatment of urinary tract infections, ultimately aiming to reduce preterm births and LBW at GPHC.

Background Smoking cessation interventions requires attending to the circumstances and needs of individual patients. We aimed at highlighting the discordances between patients' and physicians' perspectives on contextual factors that should be considered during smoking cessation. Methods We identified 36 contextual factors identified that should be considered during smoking cessation using PubMed and interviewing general practitioners. Physicians recruited through social networks campaigns and smoker or former smoker patients from the ComPaRe cohort selected the factors they considered most relevant in two online paired comparison experiment. Bradley Terry Luce models estimated the ability of each factor (i.e. the probability to be preferred). We calculated the Pearson's correlation and the intraclass correlation coefficients for the contextual factor from each perspective and compared the ranking of the 10 contextual factors with the highest abilities. Results Seven hundred and ninety-three patients' and 795 physicians' perspectives estimated the ability (i.e. importance) of the contextual factors in 11 963 paired comparisons. We found a high correlation between physicians' and patients' perspectives of the contextual factors to be considered for smoking cessation (r = 0.76, P < 0.0001). However, the agreement between the abilities of contextual factors was poor (ICC = 0.42 [−0.10; 0.75]; P = 0.09). Fine-grain analysis of participants' answers revealed many discrepancies. For example, 40% factors ranked in the top 10 most important for physicians were not in patients' top 10 ranking. Conclusion Our results highlight the importance of patient-centered care, the need to engage discussions about patients' values, beyond what is thought to be important, to avoid overlooking their real context.

Purpose: The evaluation and management of Nonarteritic Anterior Ischemic Optic Neuropathy (NAION) lacks standardized guidelines. This study aimed to investigate the real-world practices of neuro-ophthalmologists in the evaluation and management of typical NAION cases. Methods: A national survey, conducted between 2019 and 2021, involved all practicing neuro-ophthalmologists. A structured questionnaire assessed their approach to risk factor evaluation and treatment of NAION, with 19 questions about risk factors and six questions concerning treatment and prevention of fellow-eye involvement. Results: Thirty-six out of 37 neuro-ophthalmologists participated. Most physicians referred patients for evaluation of the following risk factors: obstructive sleep apnea (83.3%), diabetes mellitus (83.3%), hypertension (77.7%), dyslipidemia (72.2%), and optic disc drusen (38.8%). However, there was considerable variation in the choice of diagnostic tests recommended. Furthermore, nearly 47% recommended an embolism workup. Regarding treatment, the majority (91%) did not recommend routine treatment for NAION, although in 16.7%, high-dose corticosteroids were occasionally prescribed. Secondary prevention with aspirin (80.6%), smoking cessation advice (86.1%), and advising against erectile dysfunction medications for men (80.6%) were common recommendations. Conclusion: While the risk factors associated with NAION are well-reported, there is a lack of uniformity on which tests should be ordered to evaluate these risk factors. Most neuro-ophthalmologists concur that routine treatment for NAION is not warranted, but not unanimously. Future studies to develop a consensus guideline for post-NAION work-up and management recommendations may assist in the detection and management of preventable risk factors. [ABSTRACT FROM AUTHOR]

Background: Adolescent smoking is associated with significant health and social risks. Previous research has demonstrated the effectiveness of interventions based on behavior change theories in preventing adolescent smoking uptake. However, evidence from the theory-based perspective of evaluation is limited, especially for how such complex interventions work, and how they work when implemented in different contextual settings. Method: A comparative qualitative analysis was conducted to explore various influences on behavior change among participants taking part in two smoking prevention interventions in Northern Ireland and Bogotá. Twenty-seven focus groups were conducted in 12 schools (6 in Northern Ireland and 6 in Bogota, n = 195 pupils participated; aged 11–15 years). The Theoretical Domains Framework guided a content analysis of the data. Results: We found similarities across settings in terms of knowledge, skills, and beliefs related to smoking or vaping behavior change, as well as differences in contextual resources and social influence. Different environmental resources included availability to purchase tobacco products in the neighborhoods and previous information about tobacco risk. Participants in both interventions perceived behavioral change outcomes related to personal skills and intention to not smoke or vape. Conclusion: These findings have highlighted how both individual factors and contextual resources influence behavior change for smoking prevention in practice. Local contextual factors and social influences affecting pupils should be taken into account in the implementation and evaluation of health behavior change interventions. In particular, this study supports using social and contextual influence strategies in interventions to reduce the onset of adolescent smoking and vaping. [ABSTRACT FROM AUTHOR]

Abstract:Background: Smoking during pregnancy poses a major health risk to pregnant smokers and their children. Pregnancy could be an opportune moment for cessation. Yet many smokers do not quit during pregnancy. This study aims to explore potential influencing factors for successful smoking cessation in pregnancy. Methods: Cross-sectional data was collected in an anonymous online survey (n=358). Data of n=60 women between the 24th week of pregnancy and four months postpartum was analysed. Variables showing significant differences between women who successfully quit smoking during pregnancy ("ex-smokers", n=40) and women who were still smoking at the time of the survey ("smokers", n=20) were included in a logistic regression to identify potentially important influencing factors. Results: Ex-smokers showed higher education levels, were employed, had a planned pregnancy, abstained from alcohol during pregnancy, and scored lower on the Fagerström test for cigarette dependence. They showed greater satisfaction with life and higher scores on the personality trait "agreeableness". In the regression model, a planned pregnancy, alcohol abstinence and higher agreeableness scores increased the odds of being an ex-smoker. Conclusions: Planned pregnancies could be particularly suitable for smoking cessation. Alcohol should be considered, as abstinence could contribute to smoking cessation. A personality characterised by high agreeableness could be beneficial at least in addition to other factors. [ABSTRACT FROM AUTHOR]

Gestational diabetes mellitus is the most common medical condition in pregnancy, disproportionately affecting overweight or obese women and those from non-White populations. The lack of standardised screening and diagnostic consensus contributes to varying prevalence. Conventional risk factor-based screening can leave women undiagnosed, leading to increased risk of harm. If diet and lifestyle modifications fail to achieve glycaemic targets, prompt treatment should be initiated to manage glucose levels. A planned birth is crucial to ensure the best outcomes. Postpartum, women need screening for type 2 diabetes and other cardiometabolic risk factors, enrollment in diabetes prevention programmes, and counselling on the increased risk of future cardiometabolic disease for themselves and their offspring, highlighting the importance of ongoing prevention and management strategies.

Background and Aims: Tobacco smoking represents a major cause for preventable death and morbidity. Results from non‐randomized studies suggest that smoking cessation therapy in a residential setting might be a new viable way to facilitate smoking abstinence. We aimed to test the effects of residential multicomponent group therapy for smoking cessation compared with outpatient group therapy. Design: Prospective parallel‐group open‐label randomized superiority trial, with assessments at baseline, 6 and 12 months. Setting: Recruitment throughout Germany via media advertisements. Participants: Adult smokers (≥10 cigarettes/day) randomly assigned to residential (n = 157) or outpatient (n = 158) therapy. 51.8% female; mean age 53.2 years; mean years of smoking 34.4. Intervention and Comparator: Residential 9‐day smoking cessation group therapy comprising six daily therapy sessions and supportive interventions for cessation and daily structure embedded in the routines of a somatic rehabilitation center, compared with weekly outpatient smoking cessation group therapy (3–7 weeks) provided in routine care courses close to the participants' places of residence, both including at least 9 h of behavioral therapy. Measurements Co‐primary outcomes were self‐reported continuous 6‐ and 12‐month abstinence (hierarchically ordered). Primary analyses were conducted in the therapy‐uptake population including participants who started therapy with sensitivity analyses in the intention‐to‐treat population of all randomized participants. Findings Intervention uptake rates were 87.3% (n = 137) in the residential and 60.1% (n = 95) in the outpatient group. In the therapy‐uptake population, abstinence rates were 46.7% in the residential versus 26.3% in the outpatient group at 6 months (odds ratio [OR] = 2.46, 95% confidence interval [CI] = 1.39–4.33, P = 0.0019) and 39.4% versus 24.2% at 12 months (OR = 2.04, 95% CI = 1.14–3.64, P = 0.017). Biochemically validated abstinence rates at 12 months were 33.1% in the residential versus 17.4% in the outpatient group (OR = 2.35, 95% CI = 1.22–4.51, P = 0.011). In the intention‐to‐treat population, self‐reported and biochemically validated abstinence rates at 12 months were 34.4% in the residential versus 14.6% in the outpatient group (OR = 3.08, 95% CI = 1.77–5.34, P < 0.0001) and 28.6% versus 10.3% (OR = 3.48, 95% CI = 1.85–6.52, P = 0.0001), respectively. Conclusions: Residential therapy exclusively for smoking cessation is feasible and effective and could be a beneficial new treatment for smokers. [ABSTRACT FROM AUTHOR]

Background and Aims: Cytisine (also known as cytisinicline) is a low‐cost partial agonist of nicotinic acetylcholine receptors used to assist tobacco cessation. We aimed to review the effectiveness of cytisine for tobacco cessation and the effects of dose and co‐use of behavioural or other pharmacological interventions on cessation outcomes. Methods: We searched seven databases, Google Scholar, and reference lists of included publications for randomised controlled trials investigating use of cytisine as a tobacco cessation aid. Studies were eligible if participants were ≥15 years old and used tobacco upon study enrolment. We conducted four random effects meta‐analyses and sensitivity analyses with fixed effects models. We used the Cochrane risk‐of‐bias tool for randomised trials version 2 to assess risk of bias in included studies, with adjustments recommended by the Cochrane Tobacco Addiction Group. Results: Participants using cytisine were significantly more likely to quit tobacco than participants who received placebo/no intervention/usual care (risk ratio [RR] = 2.65, 95% confidence interval [CI] = 1.50–4.67, 6 trials, 5194 participants) or nicotine replacement therapy (RR = 1.36, 95% CI = 1.06–1.73, p = 0.0152, 2 trials, 1511 participants). The difference in cessation rates among participants receiving cytisine versus varenicline was not statistically significant (RR = 0.96, 95% CI 0.63–1.45, P = 0.8464, 3 trials, 2508 participants). Two trials examined longer versus shorter treatment duration, finding higher abstinence rates with longer treatment (RR = 1.29, 95% CI = 1.02–1.63, 2 trials, 1009 participants). The differences in the number of adverse events reported by participants who received cytisine versus placebo (RR = 1.19, 95% CI = 0.99–1.41, P = 0.0624; 6 trials; 4578 participants) or cytisine versus varenicline (RR = 1.37, 95% CI = 0.57–3.33, P = 0.4835; 2 trials; 1345 participants) were not statistically significant. Most adverse events were mild (e.g. abnormal dreams, nausea, headaches). Conclusions: Cytisine is an effective aid for tobacco cessation and appears to be more effective for tobacco cessation than placebo, no intervention, usual care and nicotine replacement therapy.

Background: Australia introduced a prescription only policy for e‐cigarettes in 2011 to prevent uptake among youth while allowing smokers to access e‐cigarettes for cessation. This is one of the restrictive forms of regulation for e‐cigarettes recommended by the World Health Organisation. Aims: To assess whether the policy has prevented e‐cigarette youth uptake and facilitated smokers' access to e‐cigarettes for cessation; and to examine a proposed toughening of the policy. Methods: An analysis of survey and administrative data on e‐cigarette use and smoking and a critical analysis of the contents of submissions to parliamentary inquiries into the policy. Results: E‐cigarette use among youth and young adults has increased steeply since 2016 but very few of these products have been obtained through the prescription system, because medical authorities discourage their use. A policy change in 2021 to increase the prescription of e‐cigarettes has not reduced e‐cigarette use among youth and only marginally increased rates of prescribing. Australian policy makers have nonetheless tightened the prescription system by banning any use of e‐cigarettes unless prescribed by a doctor and dispensed by a pharmacist. Implications: Australia's tightened prescription policy for e‐cigarettes may reduce adolescent vaping but at the risk of reducing smokers' access to e‐cigarettes and increasing the size of the illicit market for combustible cigarettes and e‐cigarettes. A more effective policy would allow vapes to be sold as consumer products by licensed tobacconists under regulations that require prior product approval, plain packaging, bans on their promotion and enforced age restrictions on purchases.

Introduction Providing access to a vape shop-based smoking cessation intervention may simultaneously increase e-cigarette use and increase the effectiveness of e-cigarettes for smoking cessation. The aim of this study was to identify the most important elements of vape shop-based smoking intervention to stakeholders who would be involved in delivering or accessing such an intervention. Aims and Methods We conducted a three-round Delphi study of vape shop staff (n  = 40), stop smoking professionals and tobacco control leads (n  = 30), and smokers, vapers, and dual users (n  = 30) in the United Kingdom in May–August 2021. In each round participants were asked whether they agreed or disagreed with statements related to vape shop-based interventions. Results Forty-six of 95 statements reached consensus in round 1, 29 out of 49 in round 2, and 8 out of 20 in round 3. There was support for a vape shop-based intervention across stakeholder groups (96%). There was consensus that the service should comprise both product (98%) and behavioral support (97%), and that quitting vaping should not be a goal of the service (79%). Although there was consensus that there should be some free product provision, there was less consensus as to what this should involve. Views were mostly consistent across stakeholder groups. Conclusions There was broad consensus on how to deliver a vape shop-based smoking cessation intervention, providing a strong basis for future intervention development and implementation. Challenges around misuse of the service and misperceptions about vaping would need to be addressed for such an intervention to be feasible and effective. Implications Many smokers who make a quit attempt using e-cigarettes purchase their vaping products in vape shops. Delivering vape-shop-based smoking cessation interventions could help to maximize the effectiveness of e-cigarettes for quitting smoking. This study used a Delphi approach to identify the most important elements of a vape shop-based intervention among stakeholders. The findings could be used to help develop future interventions.

Introduction Alaska Native and American Indian (ANAI) peoples in Alaska currently experience a disproportionate burden of morbidity and mortality from tobacco cigarette use. Financial incentives for smoking cessation are evidence-based, but a family-level incentive structure has not been evaluated. We used a community-based participatory research and qualitative approach to culturally adapt a smoking cessation intervention with ANAI families. Aims and Methods We conducted individual, semistructured telephone interviews with 12 ANAI adults who smoke, 12 adult family members, and 13 Alaska Tribal Health System stakeholders statewide between November 2022 and March 2023. Through content analysis, we explored intervention receptivity, incentive preferences, culturally aligned recruitment and intervention messaging, and future implementation needs. Results Participants were receptive to the intervention. Involving a family member was viewed as novel and aligned with ANAI cultural values of commitment to community and familial interdependence. Major themes included choosing a family member who is supportive and understanding, keeping materials positive and encouraging, and offering cash and noncash incentives for family members to choose (eg, fuel, groceries, activities). Participants indicated that messaging should emphasize family collaboration and that cessation resources and support tips should be provided. Stakeholders also reinforced that program materials should encourage the use of other existing evidence-based cessation therapies (eg, nicotine replacement, counseling). Conclusions Adaptations, grounded in ANAI cultural strengths, were made to the intervention and recruitment materials based on participant feedback. Next steps include a beta-test for feasibility and a randomized controlled trial for efficacy. Implications This is the first study to design and adapt a financial incentives intervention promoting smoking cessation among ANAI peoples and the first to involve the family system. Feedback from this formative work was used to develop a meaningful family-level incentive structure with ANAI people who smoke and family members and ensure intervention messaging is supportive and culturally aligned. The results provide qualitative knowledge that can inform future family-based interventions with ANAI communities, including our planned randomized controlled trial of the intervention.

Introduction Popular "pod-style" e-cigarettes commonly use nicotine salt-based e-liquids that cause less irritation when inhaled and can deliver higher nicotine concentrations than free-base nicotine. This study investigated the pharmacokinetic and pharmacodynamic effects of different nicotine formulations (salt vs. free-base) and concentrations that might influence systemic nicotine absorption and appeal of e-cigarettes. Aims and Methods In this randomized, double-blind, within-subject crossover study, 20 non-nicotine-naïve participants were switched among three e-liquids (free-base nicotine 20 mg/mL, nicotine salt 20 mg/mL, nicotine salt 40 mg/mL) using a refillable pod system and a standardized vaping protocol (one puff every 30 seconds, 10 puffs total). Serum nicotine concentrations and vital signs were assessed over 180 minutes; direct effects, craving, satisfaction, withdrawal, and respiratory symptoms were measured using questionnaires. CYP2A6 genotypes and the nicotine metabolite ratio were also assessed. Results Eleven (55%) participants were male and the median age was 23.5 years (range 18–67). All three formulations differed significantly in peak serum nicotine concentration (baseline adjusted Cmax, median (range): 12.0 ng/mL (1.6–27.3), 5.4 ng/mL (1.9–18.7), and 3.0 ng/mL (1.3–8.8) for nicotine salt 40 mg/mL, nicotine salt 20 mg/mL and free-base 20 mg/mL, respectively). All groups reached Cmax 2.0–2.5 minutes (median) after their last puff. Differences in subjective effects were not statistically significant. No serious adverse events were observed. Conclusions Free-base 20 mg/mL formulations achieved lower blood nicotine concentrations than nicotine salt 20 mg/mL, while 40 mg/mL nicotine salt yielded concentrations similar to cigarette smoking. The findings can inform regulatory policy regarding e-liquids and their potential use in smoking cessation. Implications Nicotine salt formulations inhaled by an e-cigarette led to higher nicotine delivery compared to nicotine-free-base formulations with the same nicotine concentration. These findings should be considered in future regulatory discussions. The 40 mg/mL nicotine salt formulation showed similar nicotine delivery as combustible cigarettes, albeit at concentrations over the maximum limit for e-liquids allowed in the European Union. Nicotine delivery resembling combustible cigarettes might be beneficial for smokers willing to quit to adequately alleviate withdrawal symptoms. However, increased nicotine delivery can also pose a public health risk, raising concerns about abuse liability, especially among youth and nonsmokers. [ABSTRACT FROM AUTHOR]

Introduction Smokeless tobacco (SLT) use in low- and middle-income countries has adverse health consequences. We hypothesize that it is feasible to test an intervention of mobile phone messages and face-to-face counseling sessions for SLT cessation in India. Aims and Methods We conducted an exploratory, individual parallel two group, randomized controlled trial (RCT), with baseline and end-point (3 months from randomization) assessments in urban primary health centers in Odisha, India. A total of 250 current (i.e. users in the last 3 months) SLT users or dual users (ie, smokers and SLT users) were recruited to the trial (125 in each group). Participants were randomized to either routine care, face-to-face counseling, and reminder mobile messages or routine care only. The primary outcomes were to assess the feasibility of running a full RCT including recruitment, compliance, and retention. Results A total of seven (77.8%) out of nine primary care centers took part in the trial. Out of the 315 SLT users invited to participate, 250 provided consent and were randomized [79.4% (95% CI: 74.5, 83.7)]. Out of the 250 randomized SLT users, 238 [95% (95% CI: 91.8, 97.5)] were followed up at 3 months (117 in the intervention group and 121 in the control group). Of the participants in the intervention group, 74 (63.8%) reported that they received the mobile messages. Conclusions This exploratory trial demonstrated the feasibility of delivering and evaluating an intervention of mobile phone messages and face-to-face counseling for SLT users in Indian primary care in a full randomized trial Implications This study found that combining mobile messages with face-to-face counseling for smokeless tobacco users visiting primary health care settings in India is feasible in terms of recruitment of users, compliance with the intervention, and retention of study participants within the trial. The biochemically verified smokeless tobacco abstinence rate was higher in the intervention group compared with the control group. There was poor agreement between self-reported tobacco cessation and the measured salivary cotinine in smokeless tobacco users. The findings support the feasibility and acceptability of the intervention signaling the need for a larger clinical trial to test the effectiveness of the intervention. [ABSTRACT FROM AUTHOR]

Introduction Encouraging smokers to quit smoking tobacco using e-cigarettes could substantially reduce smoking-related diseases. Vape shops (VS) therefore have the potential to play an important role in supporting smoking cessation. The aim of this study was to explore how to deliver a vape shop-based smoking cessation intervention in the United Kingdom. Methods Semistructured telephone interviews were undertaken with four stakeholder groups: 20 stop smoking service (SSS) providers, seven tobacco control leads, seven smokers/vapers, and five vape shop staff. Interviews were analyzed thematically. Results Stakeholder groups were positive about the idea of delivering a vape shop-based intervention. Themes that were identified were the characteristics of the intervention (duration and timing; delivery; style and content; and product provisions); barriers to the intervention (challenges for new vapers; false information; tobacco company involvement; and conflicts of interest); facilitators to the intervention (positive views on vaping; cost-effectiveness; popularity; and accessibility); and considerations for the intervention (data protection and privacy; aesthetics; and regulation and management). The results suggest that the intervention should be delivered by vape shop workers with mandatory training with the support of SSS. Most stakeholders agreed quitting vaping was not a priority, but that information on how to reduce nicotine use should be given. Concerns around privacy, General Data Protection Regulation, misinformation about vaping, and tobacco company involvement would need to be addressed. Conclusions Stakeholders agree that VS should offer stop smoking interventions and hold similar opinions on how this should be delivered. Implications This study suggests that smokers, vapers, and other key stakeholders are positive about the idea of a stop-smoking vape shop-based intervention and that they hold similar opinions on how this should be delivered. Most participants felt that this should be primarily delivered by trained vape shop staff and run with support from SSS. Participants agreed that a stop-smoking vape shop-based intervention should be flexible in terms of the type, duration, and frequency of support provided, and that the intervention should comprise both technical guidance on using a vape and behavioral support to prevent a return to smoking.

The article focuses on the development and evaluation of an online Motivational Interviewing (MI) training tool for pediatricians to improve smoking cessation support for caregivers. Topics include the effectiveness of MI for tobacco cessation, the challenges of integrating MI into pediatric care, and the design and feasibility of the online training for pediatricians.

Background: There are many tools to assist with cigarette smoking cessation (e.g., counseling, pharmacotherapy). However, tool use among cancer patients is understudied despite the consequences of continued smoking after a cancer diagnosis. Objectives: Study aims included describing and comparing cessation tool use among individuals with and without cancer who were currently smoking and who quit to determine if there are different preferences among those with cancer. Methods: Participants (N = 203) completed an online survey about demographics, cigarette use, and cessation tool use. Results: Eighty-nine participants reported being diagnosed with cancer (45 quit after diagnosis, 44 currently smoking) and 114 reported not having cancer (57 quit, 57 currently smoking). Individuals with cancer who were smoking used more evidence-based resources than those with cancer who quit (B = 1.86, SE = 0.50, p < 0.0001). Individuals with cancer who were smoking used more total cessation resources than participants without cancer who were smoking (B = 2.00, SE = 0.58, p = 0.001), but there was no difference in use of evidence-based resources between these two groups (p > 0.05). Lastly, individuals with cancer who quit also used more total cessation tools (B = 1.23, SE = 0.41, p = 0.003) and evidence-based tools (B = 1.03, SE = 0.36, p = 0.005) than those without cancer who quit. Conclusions: Individuals with cancer may be using more resources before successfully quitting. Cancer patients may need additional help to quit smoking, and further research is needed to better understand unique barriers that preclude quitting among this vulnerable population.

Background: Vaping is popular among adolescents and emerging adults; however, little is known about regular vaping patterns in older adolescents and emerging adults. Objective: The current study explored whether gender and age are associated with nicotine-based vaping frequency to ascertain ascertaining which subgroups of youth are most at-risk for frequent use. Methods: In a cross-sectional survey, participants using nicotine-based vaping devices (N=535, age range 16-24) reported frequency measured as vaping days in a week, number of episodes during which participants vaped, and puff numbers for each episode. A two-way multivariate analysis of variance was used to test the effects and interactions of gender and age groups on the three frequency outcomes. Results: Emerging adults and males vaped more frequently than their older adolescent and female counterparts, respectively. Specifically, emerging adults vaped more days per week in comparison to older adolescents, whereas males vaped more days per week and had more vaping episodes per day relative to females. Further, emerging adult males had more vaping episodes in comparison to other subgroups, and adolescent females as well as emerging adult males took more puffs per episode in comparison to emerging adult females. Conclusion: Vaping differences among subgroups suggests the need for policies to reduce regular nicotine vaping targeted toward specific gender and age groups. [ABSTRACT FROM AUTHOR]

Objectives: Smoking is an important modifiable risk factor in all vascular diseases and verbal advice from providers has been shown to increase rates of tobacco cessation. We sought to identify factors that will improve tobacco cessation and recall of receiving verbal cessation advice in vascular surgery patients at a single institution. Methods: The study is a retrospective cohort study. Patients seen in outpatient vascular surgery clinic who triggered a tobacco Best Practice Advisory (BPA) during their office visits over a 10-month period were contacted post-clinic and administered surveys detailing smoking status, cessation advice recall, and validated scales for nicotine dependence and willingness to quit smoking. This BPA is a "hard stop" that requires providers to document actions taken. Charts were reviewed for tobacco cessation documentation. Nine-digit zip-codes identified the area deprivation index, a measure of socioeconomic status. Univariate analysis was used to identify factors associated with cessation and advice recall. Results: One hundred out of 318 (31.4%) patients responded to the survey. Epic Slicer Dicer found 97 BPA responses. To dismiss the BPA, 89 providers (91.8%) selected "advised tobacco cessation" and "Unable to Advise" otherwise. Of the 318 patients, 115 (36.1%) had cessation intervention documented in their provider notes and 151 (47.5%) received written tobacco cessation advice. Of survey respondents, 70 recalled receiving verbal advice, 27 recalled receiving written advice, 28 reported receiving offers of medication/therapy for cessation. 55 patients reported having tobacco cessation plans, and among those 17 reported having quit tobacco. Recall of receiving written advice (P <.001) and recall of receiving medication/therapy (P =.008) were associated with recall of receiving verbal cessation advice. Conclusions: Providing patients with tobacco cessation medication/therapy and written tobacco cessation education during office visits is associated with increased patients' recall of tobacco cessation advice. Vascular surgeons should continue to provide directed tobacco cessation advice. [ABSTRACT FROM AUTHOR]

Introduction: Tobacco smoking is a known risk factor for cancer development and smoking cessation can lower this risk and improve outcomes in some cancer patients. Despite that, many cancer patients do not quit smoking after a cancer diagnosis, and smoking cessation counselling is still not routinely provided in cancer care. The aim of this study is to examine patterns in smoking cessation counselling to cancer patients by their treating physicians. Methods: A self-administered, web-based (mobile-friendly), anonymous questionnaire was developed on LimeSurvey and sent by e-mail to Lebanese physicians of different specialties between June 2020 and January 2022. Data were analysed using SPSS and associations between the different items were determined using the χ² test. Results: A total of 146 physicians filled out the questionnaire. Almost all physicians ask cancer patients about their smoking status, but only 45.9% provide smoking cessation counselling, and only 24% refer patients to smoking cessation counselling programs. Only 27.4% of all respondents have received formal smoking cessation training, and only 27.4% feel capable of providing smoking cessation counselling in their clinic. Specifically, family medicine physicians were more likely to provide smoking cessation counselling in the clinic (69%), more likely to refer patients to a smoking cessation counselling program (44%), and more likely to have received formal smoking cessation counselling training (67%) and more likely to feel capable of providing smoking cessation counselling (93%). Lack of training, lack of knowledge of available programs and the lack of availability of enough programs are leading obstacles contributing to low rates of smoking cessation counselling in cancer patients as reported by the physicians. Conclusion: Our data reveals a deficiency in smoking cessation counselling and referral of cancer patients to smoking cessation counselling programs in our region. This highlights the need for dedicated smoking cessation counselling training for practicing physicians and physicians in training. [ABSTRACT FROM AUTHOR]
