Abstract
INTRODUCTION Monitoring changes in cessation behaviors and cessation assistance is critical for policymaking. METHODS We analyzed two rounds (2009-2014 and 2015-2021) of Global Adult Tobacco Surveys in 13 countries. We estimated the quit ratio, quit attempt, and utilization of cessation assistance. The availability of cessation services was obtained from World Health Organization reports. We calculated absolute and relative changes in quit ratio, quit attempt, and cessation assistance. We assessed socio-economic determinants of cessation behaviors by binary logistic regression analyses on pooled data. RESULTS In all countries during both rounds smoking prevalence was 7.6-33.8%, the quit ratio was 0.15-0.54%, and the quit attempt was 17.7-52.8%. Quit ratio improved in Indonesia by 100% but declined in Turkey by 56%. Quit attempts increased in Indonesia (31.9%), Mexico (16.9%) and China (15.9%) but decreased in Turkey (140.4%), Vietnam (43.1%), and Romania (62.4%). In both rounds, using at least one method was 12.5-99.8% while the WHO-recommended method was 4.1-88.4%. In both rounds "try to quit without any assistance" and "other methods" were the most frequently reported cessation assistance. Nicotine replacement therapy (0.2-25.3%) was frequently used as recommended cessation assistance. Nicotine replacement therapy was available in most countries but not quitline and support services. CONCLUSION Limited progress was made in smoking cessation behaviors and cessation assistance in most countries. Health education to improve demand for smoking cessation and availability of evidence-based, low-cost smoking cessation assistance including quit-smoking may improve quit ratios in the population.

Incremental net monetary benefit of using varenicline for smoking cessation: A systematic review and meta-analysis of economic evaluation studies. Addiction 2024; 119:1188-1202. [PMID: 38520121 DOI: 10.1111/add.16464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 01/25/2024] [Indexed: 03/25/2024]
Abstract
AIMS To conduct a systematic review and meta-analysis and pool the incremental net benefits (INBs) of varenicline compared with behaviour support with bupropion or nicotine replacement therapy (NRT), behaviour support alone and unaided cessation in adult smokers making a first-time attempt to quit. METHODS A search for economic evaluation studies was conducted from inception to 30 September 2022, on PubMed, Embase, Cost-Effectiveness Analysis (CEA) Registry by Tufts Medical Centre, EconLit and the NHS Economic Evaluation Database (NHS EED). Eligible studies were included if they were (1) conducted among adults ages 18 years old and older who were smokers attempting to quit for the first time; (2) compared varenicline to behaviour support with bupropion or NRT, behaviour support alone and unaided cessation; and (3) performed a CEA or cost-utility analysis. The INBs were calculated and pooled across studies stratified by country income level and study perspective using the random-effects model. Statistical heterogeneity between studies was assessed using the I2 statistic and Cochrane Q statistic. RESULTS Of the 1433 identified studies, 18 studies were included in our review. Our findings from healthcare system/payer perspective suggested that the use of varenicline is statistically significantly cost-effective compared with bupropion (pooled INB, $830.75 [95% confidence interval, $208.23, $1453.28]), NRTs ($636.16 [$192.48, $1079.84]) and unaided cessation ($4212.35 [$1755.79, $6668.92]) in high-income countries. Similarly, varenicline is also found to be cost-effective compared to bupropion ($2706.27 [$1284.44, $4128.11]), NRTs ($3310.01 [$1781.53, $4838.50]) and behavioural support alone ($5438.22 [$4105.99, $6770.46]) in low- and middle-income countries. CONCLUSION Varenicline is cost-effective as a smoking cessation aid when compared with behavioural support with bupropion or nicotine replacement therapies and behavioural support alone in both high-income countries and low- and middle-income countries, from the healthcare system/payer perspective in adult smokers who attempt to quit for the first time.

Legg T, Clift B, Gilmore AB. Document analysis of the Foundation for a Smoke-Free World's scientific outputs and activities: a case study in contemporary tobacco industry agnogenesis. Tob Control 2024; 33:525-534. [PMID: 37137700 PMCID: PMC11228203 DOI: 10.1136/tc-2022-057667] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 04/05/2023] [Indexed: 05/05/2023]
Abstract
BACKGROUND Tobacco corporation Philip Morris International launched the Foundation for a Smoke-Free World (FSFW), a purportedly independent scientific organisation, in 2017. We aimed to systematically investigate FSFW's activities and outputs, comparing these with previous industry attempts to influence science, as identified in the recently developed typology of corporate influence on science, the Science for Profit Model (SPM). DESIGN We prospectively collected data on FSFW over a 4-year period, 2017-2021, and used document analysis to assess whether FSFW's activities mirror practices tobacco and other industries have historically used to shape science in their own interests. We used the SPM as an analytical framework, working deductively to search for use of the strategies it identifies, and inductively to search for any additional strategies. RESULTS Marked similarities between FSFW's practices and previous corporate attempts to influence science were observed, including: producing tobacco industry-friendly research and opinion; obscuring industry involvement in science; funding third parties which denigrate science and scientists that may threaten industry profitability; and promoting tobacco industry credibility. CONCLUSIONS Our paper identifies FSFW as a new vehicle for agnogenesis, indicating that, over 70 years since the tobacco industry began to manipulate science, efforts to protect science from its interference remain inadequate. This, combined with growing evidence that other industries are engaging in similar practices, illustrates the urgent need to develop more robust systems to protect scientific integrity.

[PMID: 38715053 PMCID: PMC11075264 DOI: 10.1186/s12992-023-01012-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 12/27/2023] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND In response to the harm caused by tobacco use worldwide, the World Health Organization (WHO) World Health Assembly actioned the WHO Framework Convention on Tobacco Control (FCTC) in 2005. To help countries meet their FCTC obligations, the WHO introduced in 2008 the MPOWER policy package and by 2020 the FCTC had been ratified by 182 parties. The package consists of six evidence-based demand reduction smoking cessation policies to assist countries to achieve best practice. We used published evaluation results and replicated the published model to estimate current policy achievement and demonstrate the impact and equity of the MPOWER policy package in reducing the global number of smokers and smoking-attributable deaths (SADs) between 2007 and 2020. METHODS We replicated an evaluation model (the Abridged SimSmoke model) used previously for country impact assessments and validated our replicated reduction in SADs for policies between 2014 and 2016 against the published results. The replicated model was then applied to report on the country level SADs averted from achieving the highest level of implementation, that is best practice in MPOWER policies, between 2016 and 2020. The latest results were then combined with past published results to estimate the reduction in SADs since the commencement of the MPOWER policy package. Country level income status was used to investigate the equity in the uptake of MPOWER policies worldwide. RESULTS Identical estimates for SADs in 41 out of 56 MPOWER policies implemented in 43 countries suggested good agreement in the model replication. The replicated model overestimated the reduction in SADs by 159,800 (1.5%) out of a total of 10.5 million SADs with three countries contributing to the majority of this replication discrepancy. Updated analysis estimated a reduction of 8.57 million smokers and 3.37 million SADs between 2016 and 2020. Between 2007 and 2020, 136 countries had adopted and maintained at least one MPOWER policy at the highest level which was associated with a reduction in 81.0 million smokers and 28.3 million SADs. Seventy five percent of this reduction was in middle income countries, 20% in high income and less than 5% in low income countries. CONCLUSIONS Considerable progress has been made by MPOWER policies to reduce the prevalence of smokers globally. However, there is inequality in the implementation and maintenance, reach and influence, and the number of SADs averted. Future research to modify the model could provide a more comprehensive evaluation of past and future progress in tobacco control policies, worldwide.

Abstract
This study examined quitting behavior and use of cessation aids (CAs) among Malaysian adult smokers aged ≥18 years (n = 1,047). Data were from the 2020 International Tobacco Control (ITC) Malaysia Survey were analyzed. A total of 79.9% of Malaysian smokers attempted to quit in the past 12 months and 85.2% intended to quit in the next 6 months. The most common CAs were e-cigarettes (ECs) (61.4%), medication/nicotine replacement therapies (NRTs; 51.0%), and printed materials (36.7%); the least common CA was infoline/quitline services (8.1%). Multivariable logistic regression analysis was performed to examine the association between sociodemographic variables and CAs use. Male smokers were more likely to use infoline/quitline services (adjusted odds ratio [aOR] = 3.27; P = .034). Malay smokers were more likely to use infoline/quitline services (aOR = 3.36; P = .002), ECs (aOR = 1.90; P = .004), printed materials (aOR = 1.79; P = .009), and in-person services (aOR = 1.75; P = .043). Most Malaysian smokers wanted to quit smoking. Furthermore, ECs were the most popular CAs, highlighting the need to assess the effectiveness of ECs for quitting smoking in Malaysia.

Abstract
INTRODUCTION In 2019, smoking prevalence in North Macedonia was one of the world's highest at around 46% in adults. However, access to smoking cessation treatment is limited and no co-ordinated smoking cessation programmes are provided in primary care. METHODS We conducted a three parallel-armed randomised controlled trial (n = 1368) to investigate effectiveness and cost-effectiveness of lung age (LA) or exhaled carbon monoxide (CO) feedback combined with very brief advice (VBA) to prompt smoking cessation compared with VBA alone, delivered by GPs in primary care in North Macedonia. All participants who decided to attempt to quit smoking were advised about accessing smoking cessation medications and were also offered behavioural support as part of the "ACT" component of VBA. Participants were aged ≥ 35 years, smoked ≥ 10 cigarettes per day, were recruited from 31 GP practices regardless of motivation to quit and were randomised (1:1:1) using a sequence generated before the start of recruitment. The primary outcome was biochemically validated 7-day point prevalence abstinence at 4 weeks (wks). Participants and GPs were not blinded to allocation after randomisation, however outcome assessors were blind to treatment allocation. RESULTS There was no evidence of a difference in biochemically confirmed quitting between intervention and control at 4wks (VBA + LA RR 0.90 (97.5%CI: 0.35, 2.27); VBA + CO RR 1.04 (97.5%CI: 0.44, 2.44)), however the absolute number of quitters was small (VBA + LA 1.6%, VBA + CO 1.8%, VBA 1.8%). A similar lack of effect was observed at 12 and 26wks, apart from in the VBA + LA arm where the point estimate was significant but the confidence intervals were very wide. In both treatment arms, a larger proportion reported a reduction in cigarettes smoked per day at 4wks (VBA + LA 1.30 (1.10, 1.54); VBA + CO 1.23 (1.03, 1.49)) compared with VBA. The point estimates indicated a similar direction of effect at 12wks and 26wks, but differences were not statistically significant. Quantitative process measures indicated high fidelity to the intervention delivery protocols, but low uptake of behavioural and pharmacological support. VBA was the dominant intervention in the health economic analyses. CONCLUSION Overall, there was no evidence that adding LA or CO to VBA increased quit rates. However, a small effect cannot be ruled out as the proportion quitting was low and therefore estimates were imprecise. There was some evidence that participants in the intervention arms were more likely to reduce the amount smoked, at least in the short term. More research is needed to find effective ways to support quitting in settings like North Macedonia where a strong smoking culture persists. TRIAL REGISTRATION The trial was registered at http://www.isrctn.com (ISRCTN54228638) on the 07/09/2018.

Systematic review of intervention functions, theoretical constructs and cultural adaptations of school-based smoking prevention interventions in low-income and middle-income countries. BMJ Open 2023; 13:e066613. [PMID: 36787979 PMCID: PMC9930567 DOI: 10.1136/bmjopen-2022-066613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 01/09/2023] [Indexed: 02/16/2023] Open
Abstract
OBJECTIVE To identify the approaches and strategies used for ensuring cultural appropriateness, intervention functions and theoretical constructs of the effective and ineffective school-based smoking prevention interventions that were implemented in low-income and middle-income countries (LMICs). DATA SOURCES Included MEDLINE, EMBASE, Global Health, PsycINFO, Web of Science and grey literature which were searched through August 2022 with no date limitations. ELIGIBILITY CRITERIA We included randomised controlled trials (RCTs) with ≥6 months follow-up assessing the effect of school-based interventions on keeping pupils never-smokers in LMICs; published in English or Arabic. DATA EXTRACTION AND SYNTHESIS Intervention data were coded according to the Theoretical Domains Framework, intervention functions of Behaviour Change Wheel and cultural appropriateness features. Using narrative synthesis we identified which cultural-adaptation features, theoretical constructs and intervention functions were associated with effectiveness. Findings were mapped against the capability-motivation and opportunity model to formulate the conclusion. Risk of bias was assessed using the Cochrane risk of bias tool. RESULTS We identified 11 RCTs (n=7712 never-smokers aged 11-15); of which five arms were effective and eight (four of the effective) arms had a low risk of bias in all criteria. Methodological heterogeneity in defining, measuring, assessing and presenting outcomes prohibited quantitative data synthesis. We identified nine components that characterised interventions that were effective in preventing pupils from smoking uptake. These include deep cultural adaptation; raising awareness of various smoking consequences; improving refusal skills of smoking offers and using never-smokers as role models and peer educators. CONCLUSION Interventions that had used deep cultural adaptation which incorporated cultural, environmental, psychological and social factors, were more likely to be effective. Effective interventions considered improving pupils' psychological capability to remain never-smokers and reducing their social and physical opportunities and reflective and automatic motivations to smoke. Future trials should use standardised measurements of smoking to allow meta-analysis in future reviews.

Global Status of Knowledge, Attitude and Practice on Tobacco Cessation Interventions Among Dental Professionals: A Systematic Review. Tob Use Insights 2022; 15:1179173X221137218. [PMID: 36601000 PMCID: PMC9806401 DOI: 10.1177/1179173x221137218] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 10/19/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND With the emergence of the WHO Framework Convention on Tobacco Control, globally the use of tobacco has decreased notably, although, it still requires efforts at individual, organizational, community level to decrease the rate further. Dental professionals are at an excellent position to provide tobacco cessation counselling and interventions, however, it is not practiced much due to lack of training and lack of knowledge. Therefore, this systematic review was conducted to assess the global status of knowledge, attitude and practice on tobacco cessation interventions among dental professionals. MATERIALS AND METHOD A systematic search of 6 databases with no language restriction since 2000 was undertaken. Studies were included if they assessed knowledge, attitude and practice on tobacco cessation interventions among dental professionals using a validated or prevalidated tool. The data obtained for assessment of knowledge, attitude, practice, curriculum and barriers were represented through heatmaps. Quality assessment of the studies was done using Newcastle Ottawa scale. RESULTS Fifty six studies were included in this systematic review. Majority of the studies were found to be of moderate quality. Knowledge regarding the tobacco cessation interventions was more theoretical than practical. All the studies showed a favorable attitude among dental professionals towards tobacco cessation intervention. CONCLUSION The included studies lack homogeneity in assessing knowledge, attitude and practice on tobacco cessation interventions. The development and validation of a standardized questionnaire to assess knowledge, attitude and practice on tobacco cessation interventions could be a potentially effective way to uniformly gather data on the subject.

Abstract
Tobacco kills more than 8 million people worldwide every year. Over 80% of the world's 1.3 billion tobacco users live in low- and middle-income countries (LMICs), where the future burden is projected to grow. At the same time, progress in tobacco control has not advanced as far as in many LMICs. In particular, the implementation of tobacco-cessation programs and interventions remains limited. The bulk of the evidence for tobacco-cessation interventions comes from high-income countries and may not reflect the context in LMICs, particularly as resources and training for tobacco cessation are limited. This paper summarizes the current evidence for tobacco-cessation interventions in LMICs and highlights some key challenges and research gaps. Overall, there is a need to build capacity for locally relevant research and implementation science to support tailored cessation interventions and strategies for LMICs.

Prevalence of smoking and smokeless tobacco use during breastfeeding: A cross-sectional secondary data analysis based on 0.32 million sample women in 78 low-income and middle-income countries. EClinicalMedicine 2022; 53:101660. [PMID: 36159043 PMCID: PMC9489519 DOI: 10.1016/j.eclinm.2022.101660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/30/2022] [Accepted: 08/30/2022] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Smoking and smokeless tobacco use during the postpartum period is well studied in high-income countries, whereas low-income and middle-income countries (LMICs) lack evidence. METHODS In this cross-sectional study we used data from the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) conducted in 78 LMICs between January 2010 and December 2019 to study tobacco use among 0.32 million sample lactating women. Age-standardized prevalence of smoking and smokeless tobacco use was estimated and presented with a 95% Confidence Interval (CI) for 78 LMICs. Pooled estimates overall and by WHO regions were obtained using random-effects meta-analyses. Country-level and community-level variance to understand contextual factors was also quantified using multilevel modelling. FINDINGS Pooled prevalence of any tobacco use among breastfeeding women in LMICs was 3.61% (95% CI 3.53-3.70); with the lowest prevalence in regions of the Americas (1.44%, 1.26-1.63) and the highest in the Southeast Asia region (6.13%, 6.0-6.27). The pooled prevalence of tobacco smoking was reported to be 1.16% (1.11-1.21), with the highest prevalence in the Eastern Mediterranean region (4.27%, 3.88-4.67) and the lowest in the African region (0.81%, 0.76-0.86). The pooled prevalence of smokeless tobacco use was reported to be 2.56% (2.49-2.63), with the highest prevalence in the Southeast Asia region (4.92%, 4.80-5.04). Illiterate and poor women in LMICs bore the enormous burden of tobacco use. INTERPRETATION The prevalence of smoking and smokeless tobacco use among lactating women in LMICs varied considerably across different WHO regions. Considering the cross-sectional design of the study, caution is required while interpreting the results. To improve mothers' and children's health and nutrition outcomes and reduce health inequalities in LMICs, reducing tobacco use through evidence-based interventions is critical. FUNDING None.

Abstract
Most adolescent tobacco control programs focus on preventing consumption, but teen smoking persists. It is uncertain whether adult-specific therapies can assist adolescents in quitting smoking. The rising incidence of smoking in low and middle-socioeconomic countries and the challenges of conducting tobacco cessation programs in these settings (due to increasing population, poor lifestyle, lack of awareness and education, professional stress, and non-compliance) need an emphasis on the scope of trials to conduct tobacco cessation in these settings. In the 11th Five Year Plan, the Indian government introduced a new National Tobacco Control Program, which currently spans 108 districts in 31 states across the country. The objective is to review the randomized control trials of selected individuals held in India and assess and evaluate the effectiveness of the steps taken by the government to help people quit tobacco consumption. These programs are important because of the hazards and impact they have on the public health indices of the nation. The government has taken steps like prohibiting smoking in public areas and banning sources. Several programs, particularly those that employed group counselling, included a range of approaches that proved beneficial in helping young people quit smoking. The RCTs mentioned are psychosocially followed by behavioral and pharmacological therapies. The challenges faced are not having participatory health care, motivating tobacco users to quit even in the short-term, adequate coverage; barriers at a different level of implementation (at a regional, state, or national level); and interference by the tobacco industry should be eliminated. The currently functioning programs in India are the National Tobacco Control Program, the National and three Regional Quitlines and mCessation.

Abstract
Introduction Tobacco use remains a global public health challenge. While studies report that smoking cessation reduces the risk of cancer and other NCDs, evidence is scarce in African region on socio-economic determinants of smoking cessation behavior. This study examined the socio-economic differentials of smoking cessation behavior among smokers in four African countries. Methods The study was conducted through secondary analysis of Global Adult Tobacco Survey (GATS) data from four African countries (Ethiopia, Kenya, Senegal and Tanzania). Smoking cessation behavior was assessed using two variables i) intention to quit smoking in next 12 months and ii) previous quit attempts made within 12 months preceding the survey. The weighted percentages for intention to quit smoking and previous quit attempts were computed. The adjusted odds ratios were computed using multinomial logistic regression to identify the association between socio-economic factors and smoking cessation behavior. Results Across the four countries studied, the previous quit attempts among smokers were in the range of 39.6% to 53.7%. Around 7.6% to 15.8% of the smokers tried to quit with an assistance. In Ethiopia over 76.5% of current smokers reported no intention to quit in next 12 months after survey, whereas the same was 50.4% in Senegal. While country specific differences were observed, females, those belonging to the poorest wealth index, unemployed and those without any formal education reported significantly lower odds of previous quit attempts or having an intention to quit smoking. Conclusion The socio-economic vulnerabilities were found to compromise smoking cessation behavior among the smokers in countries studied. Targeted interventions, adherence to smokefree laws, and provision of cessation support are essential to improve quit rates and mitigate tobacco risks among socio-economically vulnerable population.

Abstract
BACKGROUND AND AIMS Tobacco consumption and its associated adverse outcomes remain major public health issues, particularly in low- and middle-income countries. This systematic review aimed to identify and critically assess full economic evaluations for tobacco control interventions in low- and middle-income countries. METHODS Electronic databases, including EMBASE, MEDLINE and PsycINFO and the grey literature, were searched using terms such as 'tobacco', 'economic evaluation' and 'smoking' from 1994 to 2020. Study quality was assessed using the Consensus Health Economic Criteria and the Philips checklist. Studies were included which were full economic evaluations of tobacco control interventions in low- and middle-income settings. Reviews, commentaries, conference proceedings and abstracts were excluded. Study selection and quality assessment were conducted by two reviewers independently. A narrative synthesis was conducted to synthesize the findings of the studies. RESULTS This review identified 20 studies for inclusion. The studies evaluated a wide range of interventions, including tax increase, nicotine replacement therapy (nicotine patch/gum) and financial incentives. Overall, 12 interventions were reported to be cost-effective, especially tax increases for tobacco consumption and cessation counselling. There were considerable limitations regarding data sources (e.g. using cost data from other countries or assumptions due to the lack of local data) and the model structure; sensitivity analyses were inadequately described in many studies; and there were issues around the transferability of results to other settings. Additionally, the affordability of the interventions was only discussed in two studies. CONCLUSIONS There are few high-quality studies of the cost-effectiveness of tobacco use control interventions in low- and middle-income countries. The methodological limitations of the existing literatures could affect the generalizability of the findings.

Abstract
The systematic integration of evidence-based tobacco treatment has yet to be broadly viewed as a standard-of-care. The Framework Convention on Tobacco Control recommends the provision of support for tobacco cessation. We argue that the provision of smoking cessation services in clinical settings is a fundamental clinical responsibility and permits the opportunity to more effectively assist with cessation. The role of clinicians in prioritising smoking cessation is essential in all settings. Clinical benefits of implementing cessation services in hospital settings have been recognised for three decades-but have not been consistently provided. The Ottawa Model for Smoking Cessation has used an 'organisational change' approach to its introduction and has served as the basis for the introduction of cessation programmes in hospital and primary care settings in Canada and elsewhere. The significance of smoking cessation dwarfs that of many preventive interventions in primary care. Compelling evidence attests to the importance of providing cessation services as part of cancer treatment, but implementation of such programmes has been slow. We recognise that the provision of such services must reflect the realities and resources of a particular health system. In low-income and middle-income countries, access to treatment facilities pose unique challenges. The integration of cessation programmes with tuberculosis control services may offer opportunities; and standardisation of peri-operative care to include smoking cessation may not require additional resources. Mobile phones afford unique opportunities for interactive cessation programming. Health system change is fundamental to improving the provision of cessation services; clinicians can be powerful advocates for such change.

Abstract
The impact of misinformation about vapes' relative harms compared with smoking may lead to increased tobacco-related burden of disease and youth vaping. Unfortunately, vaping misinformation has proliferated. Despite growing attempts to mitigate vaping misinformation, there is still considerable ambiguity regarding the ability to effectively curb the negative impact of misinformation. To address this gap, we use a meta-analysis to evaluate the relative impact of interventions designed to mitigate vaping-related misinformation. We searched (from January 2020 till August 2021) various databases and gray literature. Only English language, original studies that employed experimental designs where participants were randomly assigned either to receive mitigating information or to a no-mitigation condition (either misinformation-only or neutral control) were included. Meta-analysis was conducted for the four eligible studies. The mean effect size of attempts to mitigate vaping misinformation was positive but not statistically significant (d = 0.383, 95% CI [-0.029, 0.796], p = .061, k = 5) with lack of evidence for publication bias. Given limited studies included, we were unable to determine factors affecting the efficacy of interventions. The limited focus on non-US studies and youth populations is concerning given the popularity of vaping in low- to middle-income countries (LMICs) and among youth. The findings of this meta-analysis describe the current state of the literature and prescribe specific recommendations to better address the proliferation of vaping misinformation, providing insights helpful in limiting the tobacco mortality burden and curtailing youth vaping.

Abstract
Oxidative stress (OS) plays a pivotal role in placental development; however, abnormal loads in oxidative stress molecules may overwhelm the placental defense mechanisms and cause pathological situations. The environment in which the mother evolves triggers an exposure of the placental tissue to chemical, physical, and biological agents of OS, with potential pathological consequences. Here we shortly review the physiological and developmental functions of OS in the placenta, and present a series of environmental pollutants inducing placental oxidative stress, for which some insights regarding the underlying mechanisms have been proposed, leading to a recapitulation of the noxious effects of OS of environmental origin upon the human placenta.

Abstract
The duration and impact of the COVID-19 pandemic depends largely on individual and societal actions which are influenced by the quality and salience of the information to which they are exposed. Unfortunately, COVID-19 misinformation has proliferated. Despite growing attempts to mitigate COVID-19 misinformation, there is still uncertainty regarding the best way to ameliorate the impact of COVID-19 misinformation. To address this gap, the current study uses a meta-analysis to evaluate the relative impact of interventions designed to mitigate COVID-19-related misinformation. We searched multiple databases and gray literature from January 2020 to September 2021. The primary outcome was COVID-19 misinformation belief. We examined study quality and meta-analysis was used to pool data with similar interventions and outcomes. 16 studies were analyzed in the meta-analysis, including data from 33378 individuals. The mean effect size of interventions to mitigate COVID-19 misinformation was positive, but not statistically significant [d = 2.018, 95% CI (-0.14, 4.18), p = .065, k = 16]. We found evidence of publication bias. Interventions were more effective in cases where participants were involved with the topic, and where text-only mitigation was used. The limited focus on non-U.S. studies and marginalized populations is concerning given the greater COVID-19 mortality burden on vulnerable communities globally.

Singh B, Chand SS, Chen H. Tobacco smoking initiation among students in Samoa and health concerns. PLoS One 2021; 16:e0258669. [PMID: 34714847 PMCID: PMC8555831 DOI: 10.1371/journal.pone.0258669] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 10/01/2021] [Indexed: 11/29/2022] Open
Abstract
Background High prevalence of tobacco smoking among young students remains a serious health concern given the positive association between smoking and NCDs. More recently, some studies also noted young smokers were more likely to get infected with COVID-19 compared to non-smokers. This study aims to assess the factors that influence smoking uptake among young students in Samoa. Findings from this study will provide valuable insight to policymakers and health authorities on policies and strategies to combat smoking among youth in Samoa and the Pacific Island Countries (PICs). Methods The 2017 Global Youth Tobacco Survey data of Samoa, available from the World Health Organization is used in the analysis. We use the multinominal logistic model to investigate the effects of socio-economic and demographics factors on young students’ uptake of smoking in Samoa. Result The main findings of this study indicate that sex, age, friendship, parental smoking, family discussion, outside influence, pocket money, and mother’s education are important determinants of tobacco smoking initiation among youths in Samoa. Conclusion Our findings contribute towards the evidence of the imperative health impact of friends, parents, and public smoking on students in Samoa. This warrants strategies that are effective in discouraging parents from smoking and implement measures that prevent smoking in public places. Moreover, educational efforts, particularly those that encourage more discussion at home settings on the harmful effects of smoking are strongly recommended. Parents are strongly encouraged to regularly monitor children’s spending behaviour.
