Abstract
Tobacco black shank (TBS), caused by Phytophthora nicotianae, is a severe disease. Plant root exudates play a crucial role in mediating plant-pathogen interactions in the rhizosphere. However, the specific interaction between key secondary metabolites present in root exudates and the mechanisms of disease resistance remains poorly understood. This study conducted a comprehensive comparison via quasi-targeted metabolomic analysis on the root exudate metabolites from the tobacco cultivar Yunyan87 and K326, both before and after inoculation with P. nicotianae. The results showed that the root exudate metabolites changed after P. nicotianae inoculation, and the root exudate metabolites of different tobacco cultivar was significantly different. Furthermore, homovanillic acid, lauric acid, and isoliquiritigenin were identified as potential key compounds for TBS resistance based on their impact on the mycelium growth of the pathogens. The pot experiment showed that isoliquiritigenin reduced the incidence by 55.2%, while lauric acid reduced it by 45.8%. This suggests that isoliquiritigenin and lauric acid have potential applications in the management of TBS. In summary, this study revealed the possible resistance mechanisms of differential metabolites in resistance of commercial tobacco cultivar, and for the first time discovered the inhibitory effects of isoliquiritigenin and homovanillic acid on P. nictianae, and attempt to use plants secondary metabolites of for plant protection.

Abstract
Nitrosamines are a class of carcinogens which have been detected widely in food, water, some pharmaceuticals as well as tobacco. The objectives of this paper include reviewing the basic information on tobacco consumption and nitrosamine contents, and assessing the health risks of tobacco nitrosamines exposure to Chinese smokers. We searched the publications in English from "Web of Science" and those in Chinese from the "China National Knowledge Infrastructure" in 2022 and collected 151 literatures with valid information. The content of main nitrosamines in tobacco, including 4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanone (NNK), N-nitrosonornicotine (NNN), N-nitrosoanatabine (NAT), N-nitrosoanabasine (NAB), total tobacco-specific nitrosamines (TSNA), and N-nitrosodimethylamine (NDMA) were summarized. The information of daily tobacco consumption of smokers in 30 provinces of China was also collected. Then, the intakes of NNN, NNK, NAT, NAB, TSNAs, and NDMA via tobacco smoke were estimated as 1534 ng/day, 591 ng/day, 685 ng/day, 81 ng/day, 2543 ng/day, and 484 ng/day by adult smokers in 30 provinces, respectively. The cancer risk (CR) values for NNN and NNK inhalation intake were further calculated as 1.44 × 10-5 and 1.95 × 10-4. The CR value for NDMA intake via tobacco smoke (inhalation: 1.66 × 10-4) indicates that NDMA is similarly dangerous in tobacco smoke when compared with the TSNAs. In China, the CR values caused by average nitrosamines intake via various exposures and their order can be estimated as the following: smoke (3.75 × 10-4) > food (1.74 × 10-4) > drinking water (1.38 × 10-5). Smokers in China averagely suffer 200% of extra cancer risk caused by nitrosamines in tobacco when compared with non-smokers.

Abstract
INTRODUCTION A substantial proportion of smokers wishing to quit do not stop smoking when using current therapies to aid cessation. Magnetic pulses to specific brain areas designated as transcranial magnetic stimulation may modulate brain activity and thereby change chemical dependencies. Deep transcranial magnetic stimulation (dTMS) with the H4 coil stimulates neuronal pathways in the lateral prefrontal cortex and insula bilaterally, areas involved in tobacco addiction. OBJECTIVE To evaluate the efficacy and safety of dTMS with T4 coil in smoking cessation. METHODS In a double blind, controlled clinical trial, adult smokers of at least 10 cigarettes/day were randomized to active (n = 50) versus sham dTMS (n = 50). The protocol involved up to 21 sessions administered over up to 12 weeks. Tobacco use was monitored by self-report and confirmed by expired air monoximetry (at each dTMS visit) and blood cotinine (at the screening visit and at the end of sessions). Participants completed abstinence, mood and cognition scales at determined timepoints during follow-up. RESULTS In the intention to-treat-analysis, the cessation rate of the intervention and control groups was 14.0%. The reported side effects were as expected for this procedure. Although there were no serious adverse events, three participants were withdrawn according to safety criteria. CONCLUSION Active treatment with dTMS H4 coil was safe but not effective for smoking cessation.

Abstract
The threat of heavy metal (HM) pollution looms large over plant growth and human health, with tobacco emerging as a highly vulnerable plant due to its exceptional absorption capacity. The widespread cultivation of tobacco intensifies these concerns, posing increased risks to human health as HMs become more pervasive in tobacco-growing soils globally. The absorption of these metals not only impedes tobacco growth and quality but also amplifies health hazards through smoking. Implementing proactive strategies to minimize HM absorption in tobacco is of paramount importance. Various approaches, encompassing chemical immobilization, transgenic modification, agronomic adjustments, and microbial interventions, have proven effective in curbing HM accumulation and mitigating associated adverse effects. However, a comprehensive review elucidating these control strategies and their mechanisms remains notably absent. This paper seeks to fill this void by examining the deleterious effects of HM exposure on tobacco plants and human health through tobacco consumption. Additionally, it provides a thorough exploration of the mechanisms responsible for reducing HM content in tobacco. The review consolidates and synthesizes recent domestic and international initiatives aimed at mitigating HM content in tobacco, delivering a comprehensive overview of their current status, benefits, and limitations.

Abstract
DNA methylation has become a biomarker of great interest in the forensic and clinical fields. In criminal investigations, the study of this epigenetic marker has allowed the development of DNA intelligence tools providing information that can be useful for investigators, such as age prediction. Following a similar trend, when the origin of a sample in a criminal scenario is unknown, the inference of an individual's lifestyle such as tobacco use and alcohol consumption could provide relevant information to help in the identification of DNA donors at the crime scene. At the same time, in the clinical domain, prediction of these trends of consumption could allow the identification of people at risk or better identification of the causes of different pathologies. In the present study, DNA methylation data from the UK AIRWAVE study was used to build two binomial logistic models for the inference of smoking and drinking status. A total of 348 individuals (116 non-smokers, 116 former smokers and 116 smokers) plus a total of 237 individuals (79 non-drinkers, 79 moderate drinkers and 79 drinkers) were used for development of tobacco and alcohol consumption prediction models, respectively. The tobacco prediction model was composed of two CpGs (cg05575921 in AHRR and cg01940273) and the alcohol prediction model three CpGs (cg06690548 in SLC7A11, cg0886875 and cg21294714 in MIR4435-2HG), providing correct classifications of 86.49% and 74.26%, respectively. Validation of the models was performed using leave-one-out cross-validation. Additionally, two independent testing sets were also assessed for tobacco and alcohol consumption. Considering that the consumption of these substances could underlie accelerated epigenetic ageing patterns, the effect of these lifestyles on the prediction of age was evaluated. To do that, a quantile regression model based on previous studies was generated, and the potential effect of tobacco and alcohol consumption with the epigenetic age was assessed. The Wilcoxon test was used to evaluate the residuals generated by the model and no significant differences were observed between the categories analyzed.

Abstract
Hispanic/Latinx (hereafter Hispanic) individuals in the United States (US) experience serious tobacco-related disparities and factors contributing to such disparities need to be adequately identified and clinically addressed. Emotion dysregulation is a key transdiagnostic relevant to smoking. The present cross-sectional investigation sought to test if emotion dysregulation was related to more severe problems during smoking quit attempts (e.g., irritability, weight gain), perceptions of difficulty about quitting, as well as negative and positive beliefs about smoking abstinence in a sample of English-speaking Hispanic adults residing in the US who smoke. Participants included 332 Hispanic adults who engaged in daily cigarette smoking (35.46 years old, 37 % identified as female). Emotion dysregulation was significantly related to more severe problems when quitting and perceived barriers for quitting, as well as negative beliefs about smoking abstinence. Additionally, emotion dysregulation was significantly and negatively related to positive outcomes about smoking abstinence. The amount of change in the various smoking criterion variables accounted for by emotion dysregulation was small (sr2 range: 0.028-0.085), but evident in adjusted models that accounted for a wide range of factors (e.g., depression, drug use severity). Overall, this investigation found consistent empirical evidence that individual differences in emotion dysregulation in Hispanic individuals were associated with several clinically significant smoking processes, suggesting this construct may represent an important factor involved in the maintenance and relapse of smoking among this ethnic population.

Abstract
BACKGROUND Flavored novel oral nicotine products (ONP), such as pouches, gum, lozenges, tablets, and gummies, have recently entered the US market but have not been authorized for smoking cessation. This study assessed the prevalence and correlates of ONPs in a national sample of youth who smoked little filtered cigars or cigarillos (LCCs) or were susceptible to LCCs. METHODS We conducted a national online survey from September-October 2022, as part of a study to develop cigar warnings among youth. Those aged 15-20 years old who reported using (ever or current) or susceptibility to little filtered cigars or cigarillos (LCCs) were eligible. Descriptive statistics and chi-square analyses assessed the prevalence of flavored ONP use and associations with other past 30-day tobacco product use and participant characteristics. RESULTS Approximately one-fifth (17.1 %) of the sample (n = 680) reported past month flavored ONP use. Any past month tobacco use was correlated with past month flavored ONP use (ps < 0.001), increasing from 17.1 % in the overall sample to 26.8 % among those reporting e-cigarette use, 41.4 % (LCCs), 47.8 % (waterpipe tobacco), 61.8 % (large cigars), and 69.1 % (smokeless tobacco). The number of products used in the past month was significantly associated with higher odds of ONPs in the past month in a multivariable logistic regression model (aOR2.26; 95 % CI: 1.92, 2.65). DISCUSSION Almost one-fifth of participants who use or are susceptible to cigar use in our national sample of youth use ONPs. Dual/poly use of other tobacco products and ONPs among youth suggests that many of these youth may be addicted to nicotine. Additional surveillance and regulation of ONPs that exhibit enticing characteristics, such as flavors, kid-friendly formulations, and targeted marketing/branding may be needed.

Abstract
BACKGROUND Adolescent nicotine and tobacco product use remains common despite declining smoking rates in the United States, likely due to the emergence of novel products. Concurrent use of multiple products may increase the risk of nicotine dependency and subsequent substance use. AIM To identify patterns and trends of dual and poly nicotine and tobacco use among adolescents in the US and explore associations of dual and poly nicotine and tobacco use with sociodemographic factors. METHODS 12 years of annual National Youth Tobacco Survey data (2011-2022) from 242,637 respondents were used to examine prevalence trends of different combinations of nicotine or tobacco product use among adolescents in the US using weighted point estimates for each year. Poisson regression models examined sociodemographic factors associated with different patterns of dual and poly-product use from 2011 to 2022. RESULTS Overall, the prevalence of dual (i.e. at least two products) and poly (i.e. at least three products) use decreased between 2011 and 2021 (from 9.5 % to 2.8 % and from 5.1 % to 1.1 %, respectively), but showed signs of increase between 2021 and 2022 (3.7 % for dual and 1.7 % for poly use). The most common combinations included a combustible product with either a novel or noncombustible product. The risk for dual and poly-product use was higher among non-Hispanic Whites, males, and high school students. CONCLUSIONS Previously declining trends in the prevalence of tobacco/nicotine dual and poly use may have been reversed. Close monitoring and targeted tobacco control policies are essential to tackle multiple product use among adolescents.

Abstract
Salicylic acid (SA) is a key phyto-hormone that is essential for plant immunity. SARD1 (SYSTEMIC ACQUIRED RESISTANCE DEFICIENT 1), a member of the CBP60 (CALMODULIN-BINDING PROTEIN60) gene family, is one of the major transcription factors regulating the expression of the genes in SA biosynthesis. SARD1 has been extensively studied in model plant Arabidopsis. However, the function of SARD1 homologues in SA biosynthesis and immune responses have rarely been investigated in other plant species. In this study, the CRISPR/CAS9 (Clustered Regularly Interspersed Short Palindromic Repeats/CAS9) technology was used in creating transgenic tobacco mutant lines with 6-8 alleles of four NtSARD1 homologous genes (NtSARD1a/1b/1c/1d) knocked out. No significant difference in morphological phenotype was observed between the transgenic knockout lines and the wild type tobacco plants, indicating that knocking out NtSARD1s does not affect the growth and development in tobacco. However, knocking out or partially knocking out of NtSARD1a/b/c/d resulted in a significantly reduced expression of NtICS1, the key gene in SA biosynthesis pathway, and thus the subsequently decreased SA/SAG accumulations in response to Pst DC3000 (Pseudomonas syrangae pv.tomato DC3000) infection, indicating a key role of NtSARD1 genes in SA biosynthesis in tobacco. As a consequence of reduced SA/SAG accumulation, the Pst DC3000-induced expression of NtPR genes as well as the resistance to Pst DC3000 were both significantly reduced in these knockout lines compared with the wild type tobacco plants. Interestingly, the reductions in the SA/SAG level, NtPR gene induction and Pst DC3000 resistance were positively correlated with the number of alleles being knocked out. Furthermore, LUC reporter gene driven by the promoter of NtICS1 containing two G(A/T)AATT(T/G) motifs could be activated by NtSARD1a, suggesting that NtSARD1a could bind to the core G(A/T)AATT(T/G) motifs and thus activate the expression of LUC reporter. Taken together, our results demonstrated that the NtSARD1 proteins play essential roles in SA biosynthesis and immune responses in tobacco. Our results also demonstrated that the CRISPR/CAS9 technology can overcome gene redundancy and is a powerful tool to study gene functions in polyploid plant species.

Abstract
OBJECTIVE This study utilized a socioecological approach to prospectively identify intrapersonal, familial, and environmental factors associated with single nicotine product use (NPU) and multiple NPU among U.S. youth. METHODS Participants were 10,029 youths (ages 12-17 years) who had completed the Population Assessment of Tobacco Health study's Wave 1 (2013-2014) and Wave 4 (2016-2018) assessments and data on past 30-day nicotine product use. Multinomial logistic regression was fit for the 3-level outcome (no use, single NPU, multiple NPU) to estimate adjusted associations between the predictors and the outcome. RESULTS The current study found that intrapersonal (sex, age, race/ethnicity, internalizing symptoms, sensation seeking, harm perceptions, lifetime history of using two or more tobacco products), familial (parental discussion about not using tobacco and living with someone who uses tobacco products) and environmental factors (exposure to tobacco advertising) commonly associated with tobacco use differentiated between individuals who later reported past 30-day NPU (either multiple or single NPU) from those who did not report past 30-day NPU. One familial factor only differentiated between lifetime users who were single NPUs from those who reported no NPU: non-combustible tobacco product use allowed anywhere in the home. Intrapersonal factors differentiated multiple NPU from single NPU: older age, being male, lifetime history of using nicotine product and less harm perceptions. CONCLUSIONS This study identified factors that may be studied to prevent any NPU, along with factors that may be studied to promote harm reduction by preventing escalation of single NPU to problematic patterns of multiple NPU.

Abstract
Mozambique ranks fifth on the list of tobacco producing countries in Africa, while also being a Party to the WHO Framework Convention on Tobacco Control (FCTC). Tobacco farming is regarded by some governments as a strategic economic commodity for export and remains deeply entrenched within Mozambique's political and economic landscape. This study uses a qualitative description methodology to identify tensions, conflicts and alignment or misalignment in policy on tobacco across government sectors and levels in Mozambique. We conducted semi-structured qualitative interviews with 33 key informants from sectors across national and subnational levels including health, agriculture, economic and commercial sectors, as well as non-state actors from civil society organizations, the tobacco industry, farmers unions and associations and individual farmers. Incoherence was present across sectoral mandates, perspectives on industry's presence in the country and regions and between FCTC provisions and informant perceptions of tobacco production as a development strategy. Despite tobacco being viewed as an important economic commodity by many informants, there was also widespread dissatisfaction with tobacco from both farmers and some government officials. There were indications of an openness to shifting to a policy that emphasizes alternatives to tobacco growing. The findings also illustrate where points of convergence exist across sectors and where opportunities for aligning tobacco policy with the provisions of the FCTC can occur.

Abstract
Although substance use is widespread across the lifespan from early adolescence to older adulthood, the prevalence of substance use disorder (SUD) differs between age groups. These age differences in SUD rates necessitate an investigation into how age moderates reward sensitivity, and consequently influences the risks and consequences related to substance use. This theoretical review integrates evidence from the literature to address the dynamic interplay between age and reward in the context of substance use. Overall, increasing evidence demonstrates that age moderates reward sensitivity and underlying reward system neurobiology. Reward sensitivity undergoes a non-linear trajectory across the lifespan. Low levels of reward sensitivity are associated with childhood and late adulthood. In contrast, high levels are associated with early to late adolescence, followed by a decline in the twenties. These fluctuations in reward sensitivity across the lifespan contribute to complex associations with substance use. This lends support to adolescence and young adulthood as vulnerable periods for the risk of subsequent SUD. More empirical research is needed to investigate reward sensitivity during SUD maintenance and recovery. Future research should also involve larger sample sizes and encompass a broader range of age groups, including older adults.

Abstract
Tomato yellow mottle-associated virus (TYMaV) belongs to the genus Cytorhabdovirus in the family Rhabdoviridae and has been reported to infect a variety of Solanaceae crops, such as Solanum lycopersicum, S. nigrum, Capsicum annuum and Nicotiana benthamiana (Li et al. 2022, Li et al. 2023, Xu et al. 2017, Zhou et al. 2019). In August 2022, about 500 out of 2000 tobacco (N. tabacum) plants showing leaf distortion, crinkling and mosaic symptoms were found in one tobacco growing field in Xingren City, Guizhou Province, China. To identify the causal pathogen(s), leaves from 20 symptomatic tobacco plants were collected and pooled to perform small RNA deep sequencing (sRNA-Seq) and assembly. Briefly, total RNA was extracted with TRIzol Reagent (Takara, Kusatsu, Japan). A small RNA cDNA library was constructed by the small RNA Sample Pre Kit. sRNA-Seq was performed with an Illumina NovaSeq 6000 platform. About 29 million reads were obtained and 334 contigs generated after removal of host-derived sequences. Among them, 31 unique contigs mapped to the TYMaV genome (NC_034240.1), covering 28.43% of the genome with the mean read coverage of 0.92%. Meanwhile, 226 contigs mapped to the genome of a potyvirus, chilli veinal mottle virus (ChiVMV, NC_005778.1), covering 88.79% of the genome with the mean read coverage of 0.83%. To verify the sRNA-Seq result for TYMaV identification, reverse transcription (RT)- PCR was performed with specific primers TYMaV-F (5'-CTGACGTAGTGTTGGCAGAT-3') and TYMaV-R (5'-AACCTCCATGCAGAACCATGG-3'). The expected-size 936-bp fragment was amplified from total RNA of all 20 samples. Dot enzyme-linked immunosorbent assays (Dot-ELISA) with antibody for TYMaV (kindly provided by Dr. Zhenggang Li from Guangdong Academy of Agricultural Sciences) were performed and further verified TYMaV infection. In addition, five asymptomatic tobacco plants from the same field as controls were used to detect TYMaV by RT-PCR and Dot-ELISA, and all samples showed negative test results. Subsequently, 17 primer pairs (Supplementary Table 1) were used to obtain the full-length sequence of TYMaV from a single positive tobacco sample by RT-PCR, followed by Sanger sequencing at Sangon Biotech (Shanghai, China). The resulting amplicon sequences were assembled into a nearly full-length genome sequence of a TYMaV isolate from tobacco in Guizhou (TYMaV-GZ). BLASTn analysis of the 13, 393 nt-long sequence (GeneBank accession number, PP444718) revealed 84.7% and 87.2% nt sequence identity with the TYMaV tomato isolate (KY075646.1) and the TYMaV S. nigrum isolate (MW527091.1), respectively. Moreover, five S. nigrum plants showing leaf crinkling and mosaic symptoms from tobacco fields tested positive for TYMaV by RT-PCR assay, suggesting a potential spread of TYMaV between tobacco and S. nigrum, which may serve as a reservoir for the virus in the tobacco fields. However, the transmission route of TYMaV remains unknown, and further verification is needed. To our knowledge, this is the first report of TYMaV infecting tobacco crop in China. It will be important to assess the potential economic importance of TYMaV to tobacco production in China and elsewhere, and to elucidate the respective roles of this virus and ChiVMV in the leaf distorting and yellowing symptoms.

Abstract
BACKGROUND Impact of donor smoking history on kidney transplant recipient outcomes is undefined. METHODS We systematically searched, critically appraised, and summarized associations between donor smoking and primary outcomes of death-censored and all-cause graft failure (DCGF, ACGF), and secondary outcomes of allograft histology, delayed graft function, serum creatinine, estimated glomerular filtration rate, and mortality. We searched MEDLINE, Embase, and Cochrane Databases from 2000 to 2023. Risk of bias was assessed using Risk of Bias in Non-randomized Studies - of Exposure tool. Quality of evidence was assessed by Grading of Recommendations Assessment, Development and Evaluation Working Group recommendations. We pooled results using inverse variance, random-effects model and reported hazard ratios for time-to-event outcomes or binomial proportions. Statistical heterogeneity was assessed with I2 statistic. RESULTS From 1785 citations, we included 17 studies. Donor smoking was associated with modestly increased DCGF (HR 1.05 (95% CI: 1.01, 1.09); I2 = 0%; low quality of evidence), predominantly in deceased donors, and ACGF in adjusted analyses (HR 1.12 (95% CI: 1.06, 1.19); I2 = 20%; very low quality of evidence). Other outcomes could not be pooled meaningfully. CONCLUSIONS Kidney donor smoking history was associated with modestly increased risk of death-censored graft failure and all-cause graft failure. This review emphasizes the need for further research, standardized reporting, and thoughtful consideration of donor factors like smoking in clinical decision-making on kidney utilization and allocation.

Abstract
INTRODUCTION In France, pregnant women generally receive written information about their pregnancy. The efficacy of these materials is limited for socially disadvantaged women, who are more likely to have lower levels of health literacy. As an alternative tool, awareness-raising videos have become popular, and the “Tuto’Tour de la grossesse” health promotion intervention has been created, which includes videos about smoking. The study objective was to evaluate the acceptability, usability, and accessibility of two videos about smoking among pregnant smokers in vulnerable situations. METHODS We conducted semi-structured interviews with these women, using a participatory approach. We then carried out a hybrid qualitative analysis, combining an analysis based on a conceptual framework and an inductive analysis. RESULTS Out of twenty participants, nine were separated from their child’s father and nine were unemployed. Twelve participants had less than a baccalaureate level of education and seven had a mother tongue other than French. Participants found the videos acceptable, usable, and accessible. We received positive feedback about the efficacy of the videos in terms of participants’ ability, opportunity, and motivation to change their behavior. Suggestions for improving the videos were made. CONCLUSIONS Other studies have looked at health promotion with similar interventions, but acceptability, usability, and accessibility have not been tested with socially disadvantaged women. These videos, which are acceptable, usable, and accessible to socially disadvantaged people, seem to have an influence on two out of three factors leading to behavior change. They could now be tested on a larger scale in a randomized controlled study.

Abstract
The health risks of smoking are widely known, but the impact of secondhand smoke on children and adolescents is often underestimated. Despite efforts to reduce smoking, exposure to secondhand smoke remains a significant public health concern, especially for young individuals. This systematic review aims to explore the health impacts of secondhand smoking on children and adolescents. Following PRISMA guidelines, 18 eligible studies from 8 countries published between 2015 and 2023 were identified through PubMed, SCOPUS, and Web of Science databases. Findings revealed that passive smoking is associated with respiratory issues like asthma and respiratory infections in children and adolescents aged 4 months to 18 years. Significant correlations were found between asthma severity and cotinine levels, a marker of passive smoking. Additionally, metabolic issues, cardiovascular effects, and ophthalmological changes, and alterations in neurocognitive functions, were noted. Urgent public health interventions are needed to reduce smoking prevalence and protect this vulnerable demographic.

Abstract
INTRODUCTION A multi-center observational study was carried out in ten ESMS, using a mixed methodology (site visits, questionnaire survey, semi-directive group interviews with professionals and individual interviews with users). PURPOSE OF THE RESEARCH The aim of this article is to describe the management and prevention of smoking in ESMS for people with mental health disorders, and to characterize and identify the smoking behaviors and representations of ESMS users and the professionals working there. RESULTS The study made it possible to distinguish between ESMS in terms of the organization of smoking areas and tobacco prevention initiatives. It also revealed that 37 percent of respondents among the professionals said they smoked tobacco, with some of them explaining that they smoked with users and sometimes gave them cigarettes. With regard to prevention, there was a consensus among professionals that they should help users who wanted to stop smoking. Professionals were divided, however, on the need for more active prevention, citing the users’ freedom and the fact that ESMS are places where people live. Among the users, 47 percent said they were smokers. Of the users who smoked, 55 percent said they wanted to stop. Interviews with the users revealed that twelve of them wanted to quit, with some asking for help and more assistance from professionals. CONCLUSIONS This report suggests that intervention research could be developed in ESMS for people with mental health disorders, who could benefit from the smoking prevention actions identified in the facilities and services investigated.

Abstract
BACKGROUND The influence of smoking on the risk of periprosthetic joint infection (PJI) remains unclear. The objective was to explore the impact of smoking on PJI after primary total knee (TKA) and hip (THA) arthroplasty. HYPOTHESIS Current smoking patients should have an increased risk of PIJ compared with nonsmoking patients. PATIENTS AND METHODS A prospective registry-based observational cohort study was performed. A total of 4591 patients who underwent primary TKA (3076 patients) or THA (1515) were included. According to the smoking status at the time of arthroplasty, patients were classified as nonsmokers (3031 patients), ex-smokers (688), and smokers (872). Multivariate analysis included smoking status, age, gender, education level, body mass index, American Society of Anesthesiologists class, diagnosis (osteoarthritis, rheumatism), diabetes, chronic obstructive pulmonary disease, perioperative blood transfusion, site of arthroplasty (knee, hip), length of operation, and length of stay. RESULTS There were PJI after 59 (1.9%) TKA and 27 (1.8%) THA (p=0.840). There were PJI in 47 (1.6%) nonsmokers, 12 (1.7%) ex-smokers, and 17 (1.9%) smokers (p=0.413). There were wound complications (delayed wound healing and superficial wound infection) in 34 (0.7%) nonsmokers, 9 (1.3%) in ex-smokers, and 17 (1.9%) in smokers (p=0.045). In multivariate analysis, only the female gender was a significant predictor of PJI (OR 1.3, 95% CI 1.1-2.4 [p=0.039]). Specifically, the categories of ex-smokers (OR 0.8, 95% CI 0.2-1.7 [p=0.241]) and smokers (OR 1.1, 95% CI 0.6-1.5 [p=0.052]) were not significant predictors. The 4-year arthroplasty survival with PJI as the endpoint was 99.1% (95% CI: 99.0-99.7) for nonsmokers, 99.0% (95% CI: 98.8-99.2) for ex-smokers, and 98.7% (95% CI: 98.2-99.0) for smokers was not significantly different between smoking status groups (p=0.318). DISCUSSION Smoking was not identified as a significant predictor for PJI following primary TKA or THA. LEVEL OF EVIDENCE III, prospective cohort study.

Abstract
BACKGROUND Many policy decisions about tobacco control are predicated on rational choice models, which posit (1) that smokers are aware of the risks of cigarettes and (2) that perceived risks have a consistent influence on continued smoking behavior. However, research shows that beliefs about smoking may be vulnerable to changes in internal and external contexts. METHODS Using ecological momentary assessment, we tested this by measuring how smokers' (N = 52) beliefs about smoking varied over time. Four times per day over 1 week, participants responded to measures of smoking intentions, risk perceptions, mood and social outcome expectancies, and internal and external contextual factors. RESULTS We analyzed this data using multilevel modeling, finding that both smoking intentions, risk perceptions, and expectancies differed between participants as well as between moments. CONCLUSION Risk perceptions and mood expectancies were a significant predictor of intentions to smoke in the next 30 min, illustrating the importance of these beliefs in decisional processes.

Abstract
Background Smoking is a major risk factor for the global burden of stroke. We have previously reported a global population attributable risk (PAR) of stroke of 12.4% associated with current smoking. In this study we aimed to explore the association of current tobacco use with different types of tobacco exposure and environmental tobacco smoke (ETS) exposure on the risk of stroke and stroke subtypes, and by regions and country income levels. Methods The INTERSTROKE study is a case-control study of acute first stroke and was undertaken with 13,462 stroke cases and 13,488 controls recruited between January 11, 2007 and August 8, 2015 in 32 countries worldwide. Association of risk of tobacco use and ETS exposure were analysed with overall stroke, ischemic and intracerebral hemorrhage (ICH), and with TOAST etiological stroke subtypes (large vessel, small vessel, cardioembolism, and undetermined). Findings Current smoking was associated with an increased risk of all stroke (odds ratio [OR] 1.64, 95% CI 1.46-1.84), and had a stronger association with ischemic stroke (OR 1.85, 95% CI 1.61-2.11) than ICH (OR 1.19 95% CI 1.00-1.41). The OR and PAR of stroke among current smokers varied significantly between regions and income levels with high income countries (HIC) having the highest odds (OR 3.02 95% CI 2.24-4.10) and PAR (18.6%, 15.1-22.8%). Among etiological subtypes of ischemic stroke, the strongest association of current smoking was seen for large vessel stroke (OR 2.16, 95% CI 1.63-2.87) and undetermined cause (OR 1.97, 95% CI 1.55-2.50). Both filtered (OR 1.73, 95% CI 1.50-1.99) and non-filtered (OR 2.59, 95% CI 1.79-3.77) cigarettes were associated with stroke risk. ETS exposure increased the risk of stroke in a dose-dependent manner, exposure for more than 10 h per week increased risk for all stroke (OR 1.95, 95% CI 1.69-2.27), ischemic stroke (OR 1.89, 95% CI 1.59-2.24) and ICH (OR 2.00, 95% CI 1.60-2.50). Interpretation There are significant variations in the magnitude of risk and PAR of stroke according to the types of tobacco used, active and ETS exposure, and countries with different income levels. Specific strategies to discourage tobacco use by any form and to build a smoke free environment should be implemented to ease the global burden of stroke.

Abstract
Drought stress inhibits seed germination, plant growth and development of tobacco, and seriously affects the yield and quality of tobacco leaves. However, the molecular mechanism underlying tobacco drought stress response remains largely unknown. In this study, integrated analysis of transcriptome and metabolome was performed on the germinated seeds of a cultivated variety K326 and its EMS mutagenic mutant M28 with great drought tolerance. The result showed that drought stress inhibited seed germination of the both varieties, while the germination rate of M28 was faster than that of K326 under drought stress. Besides, the levels of phytohormone ABA, GA19, and zeatin were increased by drought stress in M28. Five vital pathways were identified through integrated transcriptomic and metabolomic analysis, including zeatin biosynthesis, aspartate and glutamate synthesis, phenylamine metabolism, glutathione metabolism, and phenylpropanoid synthesis. Furthermore, 20 key metabolites in the above pathways were selected for further analysis of gene modular-trait relationship, and then four highly correlated modules were found. Then analysis of gene expression network was carried out of Top30 hub gene of these four modules, and 9 key candidate genes were identified, including HSP70s, XTH16s, APX, PHI-1, 14-3-3, SCP, PPO. In conclusion, our study uncovered some key drought-responsive pathways and genes of tobacco during seeds germination, providing new insights into the regulatory mechanisms of tobacco drought stress response.

Abstract
BACKGROUND Tobacco is the main risk factor for developing lung cancer. Yet, while some heavy smokers develop lung cancer at a young age, other heavy smokers never develop it, even at an advanced age, suggesting a remarkable variability in the individual susceptibility to the carcinogenic effects of tobacco. We characterized the germline profile of subjects presenting these extreme phenotypes with Whole Exome Sequencing (WES) and Machine Learning (ML). METHODS We sequenced germline DNA from heavy smokers who either developed lung adenocarcinoma at an early age (extreme cases) or who did not develop lung cancer at an advanced age (extreme controls), selected from databases including over 6600 subjects. We selected individual coding genetic variants and variant-rich genes showing a significantly different distribution between extreme cases and controls. We validated the results from our discovery cohort, in which we analysed by WES extreme cases and controls presenting similar phenotypes. We developed ML models using both cohorts. FINDINGS Mean age for extreme cases and controls was 50.7 and 79.1 years respectively, and mean tobacco consumption was 34.6 and 62.3 pack-years. We validated 16 individual variants and 33 variant-rich genes. The gene harbouring the most validated variants was HLA-A in extreme controls (4 variants in the discovery cohort, p = 3.46E-07; and 4 in the validation cohort, p = 1.67E-06). We trained ML models using as input the 16 individual variants in the discovery cohort and tested them on the validation cohort, obtaining an accuracy of 76.5% and an AUC-ROC of 83.6%. Functions of validated genes included candidate oncogenes, tumour-suppressors, DNA repair, HLA-mediated antigen presentation and regulation of proliferation, apoptosis, inflammation and immune response. INTERPRETATION Individuals presenting extreme phenotypes of high and low risk of developing tobacco-associated lung adenocarcinoma show different germline profiles. Our strategy may allow the identification of high-risk subjects and the development of new therapeutic approaches.

Abstract
Not all pregnant individuals want to become parents and "parenting intention" can also vary within individuals during different pregnancies. Nevertheless, the potential impact of parenting intention on health-related behavior during pregnancy has been heavily underexplored. In this study, we employed a within-person between pregnancy design to estimate the effect of parenting-specific influences on smoking, separate from pregnancy-specific and individual-level influences. We quantified within-mother differences in smoking during pregnancies of infants they reared (n = 84) versus pregnancies of infants they placed for adoption at birth (n = 65) using multivariate mixed-effects Poisson regression models. Mean cigarettes/day declined as the pregnancy progressed regardless of whether infants were reared or placed. However, participants smoked fewer cigarettes/day during reared pregnancies. Relative to "adopted" pregnancies, smoking during "reared" pregnancies was lower by 24%, 41%, and 54% in first (95% CI 0.64-0.90; p = 0.001), second (95% CI 0.48-0.72; p < 0.001), and third trimesters (95% CI 0.36-0.59; p < 0.001), respectively, independent of between-pregnancy differences in maternal age, fetal sex, parity, and pregnancy complications. Female sex and nulliparity were protective. Parenting intention was associated with a protective effect on pregnancy smoking independent of pregnancy-specific influences and individual characteristics. Failure to consider the impact of parenting intention on health-related behavior during pregnancy could perpetuate an unrealistic expectation to "do what's best for the baby" and stigmatize women with unintended or unwanted pregnancies.

Abstract
Tomato spotted wilt virus (TSWV) is ranked among the top 10 most destructive viruses globally. It results in abnormal leaf growth, stunting, and even death, significantly affecting crop yield and quality. Phytohormones play a crucial role in regulating plant-virus interactions. However, there is still limited research on the effect of TSWV on phytohormone levels, particularly growth hormones and genes involved in the phytohormone pathway. In our study, we combined phytohormone metabolomics and transcriptomics to examine the impact of TSWV infection on phytohormone content and gene expression profile. Metabolomic results showed that 41 metabolites, including major phytohormones and their precursors and derivatives were significantly altered after 14 days of TSWV inoculation tobacco plants cvK326, with 31 being significantly increased and 10 significantly reduced. Specifically, the levels of abscisic acid (ABA) and jasmonoyl-isoleucine (JA-Ile) were significantly reduced. The levels of indole-3-acetic acid (IAA) have remained unchanged. However, the levels of cytokinin isopentenyladenine (iP) and salicylic acid (SA) significantly increased. The transcriptome analysis revealed 2,746 genes with significant changes in expression. Out of these, 1,072 genes were significantly downregulated, while 1,674 genes were significantly upregulated. Among them, genes involved in ABA synthesis and signaling pathways, such as 9-cis-epoxycarotenoid dioxygenase (NCED), protein phosphatase 2C (PP2C), serine/threonine-protein kinase (SnRK2), and abscisic acid responsive element binding factor (ABF), exhibited significant downregulation. Additionally, expression of the lipoxygenase gene LOX, Jasmonate ZIM domain-containing protein gene JAZ, and transcription factor gene MYC were significantly down-regulated. In the cytokinin pathway, while there were no significant changes in the expression of the cytokinin synthesis genes, a significant downregulation of transcriptionally active factor type-B response regulators (type-B RRs) was observed. In terms of SA synthesis and signaling pathways, the isochorismate synthase gene ICS1 and the pathogenesis-related gene PR1 were significantly upregulated. These results can strengthen the theoretical foundation for understanding the interaction between TSWV and tobacco and provide new insights for the future prevention and control of TSWV.

Abstract
Background Tobacco use among pregnant and lactating women carries dangerous repercussions for women and their children. Limited information is available at the national level on the prevalence and determinants of tobacco use in this vulnerable sub-population of women. This study aims to estimate the prevalence of tobacco use among currently married pregnant and lactating women and its association with demographic, behavioural and regional determinants in India. Methods A cross-sectional study was conducted during which secondary data from the fifth National Family Health Survey, 2019-2020, was analysed. The prevalence and associated 95% confidence intervals (CI) for different forms of tobacco use were documented among currently married pregnant and lactating women. Adjusted Odds Ratio and 95% CI were calculated using multivariate logistic regression to identify the independent factors associated with different forms of tobacco use among respondents after applying sampling weights. Findings In India, the prevalence of tobacco use among currently married pregnant and lactating women was 2.5% and 3.2%, respectively, with over 85% of tobacco-using currently married pregnant (85.6%) and lactating (85.6%) women using smokeless tobacco (SLT) only. Age group 30-34 years, working women and the richest wealth quintile were found to be independent predictors of smoked tobacco use among currently married pregnant women. In contrast, among the currently married lactating women, the middle wealth quintile and South Indian region were found to be independent predictors of smoked tobacco use. Interpretation Smokeless tobacco was found to be the most prevalent type of tobacco consumed by pregnant and lactating women in India. There is an urgent need to curb tobacco use in this vulnerable sub-population of women in the country by sensitising them to the harmful consequences of tobacco use by integrating tobacco awareness and cessation services during routine ante-natal examinations. Funding No funding was received for this study.

Abstract
Members of the CEP (C-terminally Encoded Peptide) gene family have been shown to be involved in various developmental processes and stress responses in plants. In order to understand the roles of CEP peptides in stress response, a comprehensive bioinformatics approach was employed to identify NtCEP genes in tobacco (Nicotiana tabacum L.) and to analyze their potential roles in stress responses. Totally 21 NtCEP proteins were identified and categorized into two subgroups based on their CEP domains. Expression changes of the NtCEP genes in response to various abiotic stresses were analyzed via qRT-PCR and the results showed that a number of NtCEPs were significant up-regulated under drought, salinity, or temperature stress conditions. Furthermore, application of synthesized peptides derived from NtCEP5, NtCEP13, NtCEP14, and NtCEP17 enhanced plant tolerance to different salt stress treatments. NtCEP5, NtCEP9 and NtCEP14, and NtCEP17 peptides were able to promote osmotic tolerance of tobacco plants. The results from this study suggest that NtCEP peptides may serve as important signaling molecules in tobacco's response to abiotic stresses.

Abstract
BACKGROUND The aim of the current study was to assess the prevalence of the (problematic) consumption of alcohol, tobacco, and cannabis as well as the (problematic) use of social media, e‑products, computer games, and gambling among apprentices. METHOD Cross-sectional survey of 4591 apprentices at 17 vocational schools from Bavaria, Schleswig-Holstein, and Hamburg. Data was collected using questionnaires between March 2021 and April 2022. The primary endpoints were the 30-day prevalence and the problematic consumption and usage behavior of the mentioned substances/behaviors using screening instruments. RESULTS Among the assessed substances/behaviors, social media were used most frequently by the apprentices with a 30-day prevalence of 97.7%, followed by alcohol (64.3%) and computer games (55.8%). Cigarettes were consumed by 35.1%, e‑products by 17.9%, and cannabis by 15.4% of the apprentices. Of the apprentices, 12.2% reported having gambled in the past 30 days. Rates of problematic use were 47.4% for alcohol, 18.0% for tobacco, 6.2% for e‑products, and 1.6% for cannabis. Problematic use of social media was indicated by 45.0% of the apprentices, of gambling by 2.2%, and of computer games by 0.7%. DISCUSSION These results suggest that apprentices constitute a risk group for problematic substance use, indicating increased need for intervention. In particular, secondary prevention efforts in the areas of alcohol and social media should be taken into consideration due to their widespread prevalence in the vocational school setting.

Abstract
AIM Substance use disorders are increasingly prevalent among pregnant individuals, with evident risks of adverse perinatal outcomes. This study examines substance use (tobacco, alcohol and marijuana) among pregnant individuals with mental illness. METHODS A national representative sample of pregnant individuals were derived from 2012 to 2021 National Survey of Drug Use and Health data. Associations of past-year mental illness with past-month polysubstance use and each substance use were analyzed by logistic regression models, with complex sampling weights and survey year. RESULTS Among 6801 pregnant individuals, 16.4% reported having any mental illness (AMI) in 2012 and 2013, increasing to 23.8% in 2020-2021; and SMI increased from 3.3% to 9.4%. Polysubstance use increased disproportionately among those with severe mental illness (SMI), from 14.0% to 18.6%. Pregnant individuals with greater severity of mental illness had higher odds of polysubstance use (Adjusted Odds Ratio, 95% CI: AMI but no SMI vs. without AMI: 1.59 [1.04, 2.44]; SMI vs. without AMI: 5.48 [2.77, 10.82]). CONCLUSIONS Pregnant individuals with greater severity of mental illness were more likely to engage in substance use. Evidence-based educational, screening and treatment services, and public policy changes are warranted to mitigate the harmful health outcomes of substance use among US pregnant individuals with mental illness.

Abstract
INTRODUCTION An increasing number of states are beginning to legalize recreational cannabis use, and as such, more patients using cannabis are undergoing shoulder arthroplasty procedures. The present study sought to examine the impact of cannabis use on post-operative outcomes. The primary outcomes of interest were postoperative complications, which included infection, periprosthetic fractures, periprosthetic joint infections (PJI), dislocations, and aseptic loosening as well as medical complications. Secondary outcomes were risk factors for PJI and aseptic loosening at two-years. METHODS A private, nationwide, all-payer database (Pearldiver Technologies) was queried to identify shoulder arthroplasty patients from 2010 to 2020. Those not using tobacco or cannabis ("control", n = 10,000), tobacco users (n = 10,000), cannabis users (n = 155), and concurrent tobacco and cannabis users (n = 9,842) were identified. Risk factors for PJI and aseptic loosening at two-years were further quantified utilizing multivariable logistic regression analysis. RESULTS Compared to non-users, cannabis users experienced the highest odds for PJI and aseptic revisions, which were followed by concurrent cannabis and tobacco users and tobacco-only users. Concurrent users, as well as tobacco users were at higher risk for dislocation. Cannabis use was the most significant risk factor for PJI, followed by concurrent use and male sex. CONCLUSIONS Our study found cannabis use to cause greater risk for superficial and deep infection. More research involving randomized trials are needed to fully elucidate the impact of cannabis use on shoulder arthroplasty procedures. Clinically, these findings can appropriately guide surgeons and patients alike regarding expectations prior to undergoing TSA.

Abstract
Cigarette smoking is positively and robustly associated with cardiovascular disease (CVD), including hypertension, atherosclerosis, cardiac arrhythmias, stroke, thromboembolism, myocardial infarctions, and heart failure. However, after more than a decade of ENDS presence in the U.S. marketplace, uncertainty persists regarding the long-term health consequences of ENDS use for CVD. New approach methods (NAMs) in the field of toxicology are being developed to enhance rapid prediction of human health hazards. Recent technical advances can now consider impact of biological factors such as sex and race/ethnicity, permitting application of NAMs findings to health equity and environmental justice issues. This has been the case for hazard assessments of drugs and environmental chemicals in areas such as cardiovascular, respiratory, and developmental toxicity. Despite these advances, a shortage of widely accepted methodologies to predict the impact of ENDS use on human health slows the application of regulatory oversight and the protection of public health. Minimizing the time between the emergence of risk (e.g., ENDS use) and the administration of well-founded regulatory policy requires thoughtful consideration of the currently available sources of data, their applicability to the prediction of health outcomes, and whether these available data streams are enough to support an actionable decision. This challenge forms the basis of this white paper on how best to reveal potential toxicities of ENDS use in the human cardiovascular system-a primary target of conventional tobacco smoking. We identify current approaches used to evaluate the impacts of tobacco on cardiovascular health, in particular emerging techniques that replace, reduce, and refine slower and more costly animal models with NAMs platforms that can be applied to tobacco regulatory science. The limitations of these emerging platforms are addressed, and systems biology approaches to close the knowledge gap between traditional models and NAMs are proposed. It is hoped that these suggestions and their adoption within the greater scientific community will result in fresh data streams that will support and enhance the scientific evaluation and subsequent decision-making of tobacco regulatory agencies worldwide.

Abstract
OBJECTIVE While e-cigarette use is associated with adverse cardiopulmonary health effects, the mortality risks associated with e-cigarette use alone and combined with smoking remain unexamined. METHODS Data between 2014 and 2018 were obtained from the National Health Interview Survey (NHIS), an annual cross-sectional survey of US adults. All-cause mortality and date of death were obtained via linkage of the NHIS to the National Death Index through December 31, 2019. A 6-category composite cigarette (never, former, current) and e-cigarette (current, non-current) exposure variable was created. We examined the association of cigarette and e-cigarette use patterns with all-cause mortality using adjusted Cox models. RESULTS Among 145,390 participants (79,294 women [51.5%]; 60,560 aged 18-44 [47.4%]), 5220 deaths were observed over a median follow-up of 3.5 years (508,545 total person-years). Dual use of cigarettes and e-cigarettes was associated with higher mortality risk compared with non-current e-cigarette use in combination with never smoking (hazard ratio [HR] 2.44; 95% CI, 1.90-3.13) and had a risk that did not differ from current exclusive smoking (HR, 1.06; 95% CI, 0.83-1.37). Current e-cigarette use in combination with former smoking was associated with a lower mortality risk than current exclusive cigarette smoking (HR 0.64; 95% CI, 0.41-0.99). CONCLUSIONS The addition of e-cigarette use to smoking does not reduce mortality risk compared with exclusive smoking. However, transitioning completely from cigarettes to e-cigarettes may be associated with mortality risk reduction. Further research is needed to verify these findings in larger cohorts and over longer periods of follow-up.

Abstract
Background Despite the increasing prevalence of anxiety disorders in Korea, there have been no nationwide studies on the association between tobacco status and generalized anxiety disorder (GAD). Furthermore, despite the increasing number of people using noncombustible nicotine or tobacco products (NNTPs), the association between NNTP use and GAD remains unclear. Therefore, this study investigated the association between tobacco use and GAD. Methods This nationwide study used data from the 8th Korea National Health and Nutrition Examination Survey (2021) and included 5,454 adults aged ≥19 years who self-reported on the tobacco use and mental health sections. Multivariable logistic regression analysis was performed to investigate the odds ratios (ORs) of GAD (Generalized Anxiety Disorder-7 score ≥10) according to tobacco status among Korean adults. The severity of anxiety was assessed using the Generalized Anxiety Disorder-7 scale. Results Compared to never tobacco users, the ORs of GAD for combustible cigarette smokers and NNTP users were 2.74 (95% confidence interval [CI], 1.66-4.50) and 2.11 (95% CI, 1.16-3.83), respectively. The OR of GAD for former tobacco users was 1.63 (95% CI, 0.98-2.72). Conclusion Tobacco use (combustible cigarettes and NNTP) was positively associated with GAD. However, in former tobacco users, there was no significant association with GAD when compared with never tobacco users. Given the OR of GAD among tobacco users, it is crucial to pay attention to screening for GAD and implement appropriate early interventions.

Abstract
INTRODUCTION The expansion of new tobacco consumption formats and electronic vapor products threatens to reverse the trend of declining smoking rates that had been observed among younger people in recent decades. Early detection in the health sector requires screening tools that have been adapted and validated in our context. This study aims to translate, culturally adapt, pilot and empirically validate the Hooked on Nicotine Checklist (HONC) with Spanish adolescents. METHODS The process of translation and cultural adaptation included the following stages: direct translation, synthesis of translations, back translation, consolidation with a committee of experts and pre-test, along with a cognitive interview, which served as pilot testing. Empirical validation was conducted with a sample of 1027 adolescents aged between 12 and 18 (M=15.40; SD=1.638). RESULTS The results obtained confirm that the HONC is a brief, clear and easy-to-understand tool, with appropriate psychometric properties. A Cronbach's alpha value of 0.90 was obtained. Sensitivity, specificity, PPV and NPV indices reached values of 0.56, 0.94, 0.79 and 0.83, respectively. Cut-off point 1 is the one reaching the best balance between the two values. CFA showed a model good overall fit. CONCLUSION This study makes the Spanish version of the HONC available to researchers and clinicians, so that it can be used with sufficient psychometric guarantees.

Abstract
INTRODUCTION The Stoptober House is part of the annual national Stoptober smoking cessation campaign in the Netherlands. During the first week of October, 48 volunteers resided in the tobacco-free Stoptober House for 5 days and received smoking cessation counseling. This pilot study explored how the Stoptober House may have facilitated smoking cessation among participants. METHODS We included 48 individuals who were selected for the Stoptober House (intervention group) and 67 individuals who were not selected (control group). Surveys were conducted at baseline, immediately after 2 and 8 weeks of post-intervention. We compared self-reported abstinence, psychosocial mediators related to smoking cessation, and perceived active elements of the Stoptober House between the intervention and control groups using t/χ2 tests and linear mixed model (LMM) analysis. Sixteen semi-structured qualitative interviews were conducted to explore participants' perspectives on the elements contributing to their success in quitting smoking. RESULTS At 8 weeks of follow-up, a higher proportion of participants in the intervention group (24/48 [50%]) reported being abstinent compared to the control group (5/67 [7%]; p < 0.001). Among participants who reported making a quit attempt, 22/38 (57.9%) in the intervention group remained abstinent compared to 4/17 (23.5%) in the control group (p = 0.022). The intervention group also exhibited higher self-efficacy to quit smoking throughout the follow-up period and higher social support immediately after the Stoptober House. No significant differences were observed in other psychosocial factors. The interviews highlighted several perceived elements of the Stoptober House that contributed to smoking cessation success, including restricted smoking opportunities, access to smoking cessation counselors, and peer support. CONCLUSION This pilot study suggests that the Stoptober House provides support that can help people quit smoking. Further research is needed to confirm these findings and determine the cost-effectiveness of this intervention in promoting long-term abstinence among specific groups of smokers.

Abstract
BACKGROUND Non-communicable diseases (NCDs) are the leading causes of death worldwide. Systems approaches have potential for creating sustainable outcomes at scale but have rarely been used to support scale up in physical activity/nutrition promotion or NCD prevention more generally. This review aimed to: (i) synthesise evidence on the use of systems approaches in scaling up interventions targeting four behavioural risk factors for NCDs; and (ii) to explore how systems approaches have been conceptualised and used in intervention implementation and scale up. METHOD Seven electronic databases were searched for studies published 2016-2021. Eligible studies targeted at least one of four NCD behavioural risk factors (physical inactivity, tobacco use, alcohol consumption, diet), or described evaluation of an intervention planned for or scaled up. Studies were categorised as having a (i) high, (ii) moderate, or (iii) no use of a systems approach. A narrative synthesis of how systems approaches had been operationalised in scale up, following PRISMA guidelines. RESULTS Twenty-one intervention studies were included. Only 19% (n = 4) of interventions explicitly used systems thinking to inform intervention design, implementation and scale up (targeting all four risk factors n = 2, diet n = 1, tobacco use n = 1). Five studies ('high use') planned and implemented scale up with an explicit focus on relations between system elements and used system changes to drive impact at scale. Seven studies ('moderate use') considered systems elements impacting scale-up processes or outcomes but did not require achieving system-level changes from the outset. Nine studies ('no use') were designed to work at multiple levels among multiple agencies in an intervention setting, but the complexity of the system and relations between system elements was not articulated. We synthesised reported barriers and facilitators to scaling up, and how studies within each group conceptualised and used systems approaches, and methods, frameworks and principles for scaling up. CONCLUSION In physical activity research, and NCD prevention more broadly, the use of systems approaches in scale up remains in its infancy. For researchers, practitioners and policymakers wishing to adopt systems approaches to intervention implementation at scale, guidance is needed on how to communicate and operationalise systems approaches in research and in practice.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is a commonly occurring malignancy with complex genetic alterations contributing to its development. The H-Ras, a proto-oncogene, becomes an oncogene when mutated and has been implicated in various cancers. This systematic review aims to research to what extent H-Ras expression and mutation contribute to the development and progression of OSCC, and how does this molecular alteration impacts the clinical characteristics and prognosis in patients with OSCC. METHODS A thorough electronic scientific literature search was carried out in PUBMED, SCOPUS, and GOOGLE SCHOLAR databases from 2007 to 2021. The search strategy yielded 120 articles. Following aggregation and filtering all results through our inclusion and exclusion criteria total 9 articles were included in our literature review. It has also been registered with PROSPERO (CRD42023485202). RESULTS It was found that mutations in the Ras gene commonly reported in hotspots at codons 12, 13, and 61 resulting in the activation of downstream signaling pathways causing abnormal and uncontrolled cell growth. This systematic review has shown an increased prevalence of H-Ras mutation in well-differentiated OSCC and also the prevalence of H-Ras mutation in individuals engaging in multiple risk behaviors, particularly chewing tobacco, demonstrated a significant association with a higher prevalence of H-Ras positivity. CONCLUSION This review sheds light on the prevalence of H-Ras mutations, their association with clinical characteristics, and their potential implications for OSCC prognosis. It also enhances our comprehension of the molecular mechanisms that underlie OSCC and paves the way for further research into targeted treatments based on H-Ras alterations.

Abstract
RATIONALE The lung microbiome is an inflammatory stimulus whose role in the development of lung malignancies is incompletely understood. We hypothesized that the lung microbiome associates with multiple clinical factors, including the presence of a lung malignancy. OBJECTIVES To assess associations between the upper and lower airway microbiome and multiple clinical factors including lung malignancy. METHODS We conducted a prospective cohort study of upper and lower airway microbiome samples from 44 subjects undergoing lung lobectomy for suspected or confirmed lung cancer. Subjects provided oral (2), induced sputum, nasopharyngeal, bronchial, and lung tissue (3) samples. Pathologic diagnosis, age, tobacco use, dental care history, lung function, and inhaled corticosteroid use were associated with upper and lower airway microbiome findings. MEASUREMENTS AND MAIN RESULTS Older age was associated with greater Simpson diversity in the oral and nasopharyngeal sites (p = 0.022 and p = 0.019, respectively). Current tobacco use was associated with greater lung and bronchus Simpson diversity (p < 0.0001). Self-reported last profession dental cleaning more than 6 months prior (vs. 6 or fewer months prior) was associated with lower lung and bronchus Simpson diversity (p < 0.0001). Diagnosis of a lung adenocarcinoma (vs. other pathologic findings) was associated with lower bronchus and lung Simpson diversity (p = 0.024). Last professional dental cleaning, dichotomized as ≤ 6 months vs. >6 months prior, was associated with clustering among lung samples (p = 0.027, R2 = 0.016). Current tobacco use was associated with greater abundance of pulmonary pathogens Mycoplasmoides and Haemophilus in lower airway samples. Self-reported professional dental cleaning ≤ 6 months prior (vs. >6 months prior) was associated with greater bronchial Actinomyces and lung Streptococcus abundance. Lung adenocarcinoma (vs. no lung adenocarcinoma) was associated with lower Lawsonella abundance in lung samples. Inhaled corticosteroid use was associated with greater abundance of Haemophilus among oral samples and greater Staphylococcus among lung samples. CONCLUSIONS Current tobacco use, recent dental cleaning, and a diagnosis of adenocarcinoma are associated with lung and bronchial microbiome α-diversity, composition (β-diversity), and the abundance of several respiratory pathogens. These findings suggest that modifiable habits (tobacco use and dental care) may influence the lower airway microbiome. Larger controlled studies to investigate these potential associations are warranted.

Abstract
E-cigarettes are a popular mode of delivery for nicotine, tobacco and cannabis. The prevalence of vaping among youth is increasing and this review aims to identify features of the neighbourhood environment, e.g., retailers, advertisements, and policies, that are associated with youth vaping. We included 48 studies. Of these, approximately 40% and 60% reported that presence of e-cigarette retailers, and advertisements, was associated with statistically higher odds of e-cigarette use in youth, respectively. Approximately 30% of studies reported that policies affecting e-cigarette availability were associated with statistically lower odds of vaping. Identifying these influential features of the neighbourhood environment will help formulate appropriate policies to reduce e-cigarette use among youth.

Abstract
The TIFY gene family plays an essential role in plant development and abiotic and biotic stress responses. In this study, genome-wide identification of TIFY members in tobacco and their expression pattern analysis in response to Ralstonia solanacearum infection were performed. A total of 33 TIFY genes were identified, including the TIFY, PPD, ZIM&ZML and JAZ subfamilies. Promoter analysis results indicated that a quantity of light-response, drought-response, SA-response and JA-response cis-elements exist in promoter regions. The TIFY gene family exhibited expansion and possessed gene redundancy resulting from tobacco ploidy change. In addition, most NtTIFYs equivalently expressed in roots, stems and leaves, while NtTIFY1, NtTIFY4, NtTIFY18 and NtTIFY30 preferentially expressed in roots. The JAZ III clade showed significant expression changes after inoculation with R. solanacearum, and the expression of NtTIFY7 in resistant varieties, compared with susceptible varieties, was more stably induced. Furthermore, NtTIFY7-silenced plants, compared with the control plants, were more susceptible to bacterial wilt. These results lay a foundation for exploring the evolutionary history of TIFY gene family and revealing gene function of NtTIFYs in tobacco bacterial wilt resistance.

Abstract
To enhance the quality of tobacco leaves and optimize the smoking experience, diverse strains of functional bacteria and their associated metabolites have been used in tobacco aging. Exogenous cellulase additives are frequently employed to facilitate the degradation of cellulose and other macromolecular matrices and enhance the quality of the tobacco product. However, little is known about how microbial metabolites present in exogenous enzyme additives affect tobacco quality. In this study, crude cellulase solutions, produced by a tobacco-originating bacterium Bacillus subtilis FX-1 were employed on flue-cured tobacco. The incorporation of cellulase solutions resulted in the reduction of cellulose crystallinity in tobacco and the enhancement of the overall sensory quality of tobacco. Notably, tobacco treated with cellulase obtained from laboratory flask fermentation demonstrated superior scent and flavor attributes in comparison to tobacco treated with enzymes derived from industrial bioreactor fermentation. The targeted and untargeted metabolomic analysis revealed the presence of diverse flavor-related precursors and components in the cellulase additives, encompassing sugars, alcohols, amino acids, organic acids, and others. The majority of these metabolites exhibited significantly higher levels in the flask group compared to the bioreactor group, probably contributing to a pronounced enhancement in the sensory quality of tobacco. Our findings suggest that the utilization of metabolic products derived from B. subtilis FX-1 as additives in flue-cured tobacco holds promise as a viable approach for enhancing sensory attributes, establishing a solid theoretical foundation for the potential development of innovative tobacco aging additives.

Abstract
INTRODUCTION Cigarettes are frequently co-used with alcohol and cannabis. However, definitions of co-use vary and the extent to which cigarette use changes on days with different patterns of co-use is unclear. We compared the number of cigarettes smoked on different days based on co-use patterns of cigarettes and alcohol or cannabis. METHODS This study analyzed 2408 smoking days collected in a 30-day smartphone-based daily diary study among 146 young adults (aged 18-26) with an oversample from sexual minority groups. Two separate multilevel models were estimated: one for cigarette and alcohol co-use and the other for cigarette and cannabis co-use. Both models examined day-level associations between the number of cigarettes smoked and 3 different types of days (smoking-only days, same-occasion co-use days, different-occasion co-use days), controlling for demographic characteristics. RESULTS More cigarettes were smoked on same-occasion co-use days compared to cigarette-smoking-only days for both alcohol (b=1.474, SE=0.136, t=10.8, p<.001) and cannabis (b=0.822, SE=0.209, t=3.9, p<.001). There were no significant differences in cigarettes smoked on days with co-use on the same day, but on different occasions, compared to days with smoking only. CONCLUSIONS Compared to days with cigarette smoking only, more cigarettes are smoked on days when cigarettes are co-used with alcohol or cannabis on the same occasion, while the same is not true for days with co-use on different occasions. Conflating different definitions of co-use may impact findings on associations between co-use and smoking behavior.

Abstract
The use of menthol in tobacco products has been linked to an increased likelihood of developing nicotine dependence. The widespread use of menthol can be attributed to its unique sensory characteristics; however, emerging evidence suggests that menthol also alters sensitivity to nicotine through modulation of nicotinic acetylcholine receptors (nAChRs). Nicotinic subunits, such as β2 and α5, are of interest due to their implications in nicotine reward, reinforcement, intake regulation, and aversion. This study, therefore, examined the in vivo relevance of β2 and α5 nicotinic subunits on the pharmacological and behavioral effects of menthol. Data suggests that the α5 nicotinic subunit modulates menthol intake in mice. Overall, deletion or a reduction in function of the α5 subunit lessened aversion to menthol. α5 KO mice and mice possessing the humanized α5 SNP, a variant that confers a nicotine dependence phenotype in humans, demonstrated increased menthol intake compared to their WT counterparts and in a sex-related fashion for α5 SNP mice. We further reported that the modulatory effects of the α5 subunit do not extend to other aversive tastants like quinine, suggesting that deficits in α5* nAChR signaling may not abolish general sensitivity to the aversive effects of other noxious chemicals. Further probing into the role of α5 in other pharmacological properties of menthol revealed that the α5 subunit does not modulate the antinociceptive properties of menthol in mice and suggests that the in vivo differences observed are likely not due to the direct effects of menthol on α5-containing nAChRs in vitro.

Abstract
The DELAY OF GERMINATION1-LIKE (DOGL) genes play an essential role in diverse biological processes in plants. However, their exact involvement in the response to cadmium (Cd) stress via the ABA pathway remains unclear. Here, we focused on NtDOGL4, a tobacco DOGL gene whose expression is highly induced upon exposure to Cd. Overexpression of NtDOGL4 in tobacco resulted in elevated endogenous ABA levels, reduced Cd accumulation, and increased tolerance to Cd. Moreover, NtDOGL4 overexpression led to decreased accumulation of reactive oxygen species (ROS) and improved ROS scavenging capacity under Cd stress. Further analyses revealed the direct binding of the transcription factor ABSCISIC ACID-INSENSITIVE 5 (ABI5) to the NtDOGL4 promoter, positively regulating its expression in tobacco. Notably, NtDOGL4 overexpression promoted suberin formation and deposition, while suppressing the expression of Cd transporter genes in tobacco roots, as evidenced by histochemical staining, suberin fraction determination, and qRT-PCR assays. Collectively, our results demonstrate that NtDOGL4 overexpression reduces Cd accumulation, thereby improving Cd stress tolerance through the modulation of antioxidant system, transcription of Cd transporters, and suberin deposition. Notably, the NtABI5-NtDOGL4 module functions as a positive regulator in tobacco's Cd tolerance, underscoring its potential as a molecular target for developing low-Cd crops to ensure environmental safety.

Abstract
Tobacco remains one of the most commercially important crops due to the parasympathomimetic alkaloid nicotine used in cigarettes. Most genes involved in nicotine biosynthesis are expressed in root tissues; however, their light-dependent regulation has not been studied. Here, we identified the ELONGATED HYPOCOTYL 5 homolog, NtHY5, from Nicotiana tabacum and demonstrated that NtHY5 could complement the Arabidopsis thaliana hy5 mutant at molecular, morphological and biochemical levels. We report the development of CRISPR/Cas9-based knockout mutant plants of tobacco, NtHY5CR, and show down-regulation of the nicotine and phenylpropanoid pathway genes leading to a significant reduction in nicotine and flavonol content, whereas NtHY5 overexpression (NtHY5OX) plants show the opposite effect. Grafting experiments using wild-type, NtHY5CR, and NtHY5OX indicated that NtHY5 moves from shoot-to-root to regulate nicotine biosynthesis in the root tissue. Shoot HY5, directly or through enhancing expression of the root HY5, promotes nicotine biosynthesis by binding to light-responsive G-boxes present in the NtPMT, NtQPT and NtODC promoters. We conclude that the mobility of HY5 from shoot-to-root regulates light-dependent nicotine biosynthesis. The CRISPR/Cas9-based mutants developed, in this study; with low nicotine accumulation in leaves could help people to overcome their nicotine addiction and the risk of death.

Abstract
Exposure to organic ultraviolet (UV) filters has raised concerns due to their potential adverse effects on environments. However, their toxic mechanisms on plants remain elusive. In this study, using integrative physiological and transcriptomic approaches we investigated the physiological and molecular responses to three representative UV filters, namely oxybenzone (OBZ), avobenzone (AVB), and octinoxate (OMC), in an agricultural model plant tobacco. The exposure to UV filters disrupts the functionality of photosystem reaction centers and the light-harvesting apparatus. Concurrently, UV filters exert a suppressive effect on the expression of genes encoding Rubisco and Calvin-Benson cycle enzymes, resulting in a decreased efficiency of the Calvin-Benson cycle and consequently hampering the process of photosynthesis. Exposure to UV filters leads to significant generation of reactive oxygen species within tobacco leaves and downregulation of oxidoreductase activities. Moreover, UV filters promote abscisic acid (ABA) accumulation by inducing the expression of ABA biosynthesis genes whereas repress indole-3-acetic acid (IAA) biosynthesis gene expression, which induce leaf yellowing and slow plant growth. In summary, the organic UV filters exert toxic effects on tobacco growth by inhibiting chlorophyll synthesis, photosynthesis, and the Calvin-Benson cycle, while generating excessive reactive oxygen species. This study sheds light on the toxic and tolerance mechanisms of UV filters in agricultural crops.

Abstract
BACKGROUND Hydrogen sulfide (H2S) is a novel signaling molecule involved in the growth and development of plants and their response to stress. However, the involvement of H2S in promoting the growth and development of tobacco plants is still unclear. RESULTS In this study, we explored the effect of pre-soaking or irrigating the roots of tobacco plants with 0.0, 2.0, 4.0, 6.0, and 8.0 mM of sodium hydrosulfide (NaHS) on endogenous H2S production, antioxidant enzymatic and cysteine desulfhydrase activities, seed germination, agronomic traits, photosynthetic pigments contents, and root vigor. The results revealed that exogenous NaHS treatment could significantly promote endogenous H2S production by inducing gene expression of D/L-CD and the activities of D/L-CD enzymes. Additionally, a significant increase in the agronomic traits and the contents of photosynthetic pigments, and no significant difference in carotenoid content among tobacco plants treated with 0.0 to 8.0 mM of NaHS was observed. Additionally, a significant increase in the germination speed, dry weight, and vigor of tobacco seeds, whereas no significant effect on the percentage of seed germination was observed on NaHS treatment. Furthermore, NaHS treatment could significantly increase the activity of superoxide dismutase (SOD) and peroxidase (POD) enzymes, which reduces damage due to oxidative stress by maintaining reactive oxygen species homeostasis. CONCLUSIONS These results would aid in enhancing our understanding of the involvement of H2S, a novel signaling molecule to promote the growth and development of tobacco plants.

Abstract
Domains of unknown function (DUF) proteins represent a large group of uncharacterized protein families. The DUF868 gene family in Nicotiana has not yet been described. In the present study, we identified 12, 11, and 25 DUF868 family members in the genome of Nicotiana sylvestris, N. tomentosiformis, and N. tabacum, respectively. Based on phylogenetic analysis, these were categorized into five groups (A-E). Within each group, the gene structures, motifs, and tertiary structures showed high similarity. NtDUF868 family expansion during evolution was mainly driven by segmental duplication events. MicroRNA (miRNA) target site prediction identified 12 miRNA members that target 16 NtDUF868 family genes. The promoters of these genes contain cis-regulatory elements responsive to light, phytohormones, and abiotic stresses. Expression profiling revealed their tissue- and stage-specific expression patterns. RNA-sequencing and quantitative reverse transcription PCR revealed that the NtDUF868 family genes are potentially involved in the response to abiotic and biotic stresses, particularly drought and hormone stresses, and in the resistance to black shank and bacterial wilt. We generated transformed plants using NtDUF868-E5 overexpression and gene-editing vectors. NtDUF868-E5 overexpression resulted in enhanced tobacco plant growth and development, leading to increased leaf photosynthetic capacity and higher chlorophyll and carotenoid contents. This study provided a comprehensive genome-wide analysis of the DUF868 gene family, shedding light on their potential roles in plant growth and stress responses.

Abstract
Colonialism's enduring impact on Brazil has had significant implications for health and oncology outcomes. This historical essay delves into the profound changes brought about by the transatlantic slave trade from Africa to the Americas, particularly in terms of its influence on the economy, sociocultural habits, and health outcomes. This essay explores the enduring connections between the colonial period's operational dynamics in Brazil and the current epidemiological panorama of head and neck cancer (HNC). The examination provides original insights on the role of tobacco and alcohol production and consumption, alongside the investigation of structural racism, which contributes to disparities in access to diagnosis, treatment, and prognosis for patients with HNC. This article presents novel visions and an analysis of evidence-based strategies to disrupt the adverse impact of colonialism's legacy on the epidemiology of HNC in Brazil.

Abstract
OBJECTIVES patients with cancer who smoke have more side effects during and after treatment, and a lower survival rate than patients with cancer who quit smoking. Supporting patients with cancer to quit smoking should be standard care. The aim of this systematic review was to determine the most effective smoking cessation method for patients diagnosed with cancer. METHODS PubMed, Embase, Web of Science and Google Scholar were systematically searched. Included were randomized controlled trials and observational studies published after January 2000 with any smoking cessation intervention in patients with any type of cancer. Result of these studies were evaluated in a meta-analysis. RESULTS A total of 18,780 papers were retrieved. After duplicate removal and exclusion based on title and abstract, 72 publications were left. After full text screening, 19 (randomized) controlled trials and 20 observational studies were included. The overall methodological quality of the included studies, rated by GRADE criteria, was very low. Two out of 21 combined intervention trials showed a statistical significant effect. Meta-analysis of 18 RCTs and 3 observational studies showed a significant benefit of combined modality interventions (OR 1.67, 95% C.I.: 1.24-2.26, p = 0.0008) and behavioural interventions (OR 1.33, 95% C.I.: 1.02 - 1.74, p = 0.03), but not for single modality pharmacological interventions (OR 1.11; 95% C.I.: 0.69-1.78, p = 0.66). CONCLUSION A combination of pharmacological and behavioural interventions may be the most effective intervention for smoking cessation in patients with cancer.
