RESUMO

The objective of this study is to determine risk factors that may contribute to exclusion decision from recombinant tissue plasminogen activator (rtPA) in patients with acute ischemic stroke (AIS) with a combined current or history of smoking and obesity. This study was conducted on data from 5469 patients with AIS collected from a regional stroke registry. Risk factors associated with inclusion or exclusion from rtPA were determined using multivariate logistic regression analysis. The adjusted odds ratios and 95% confidence interval for each risk factor were used to predict the increasing odds of an association of a specific risk factor with exclusion from rtPA. In the adjusted analysis, obese patients with AIS with a history of smoking (current and previous) excluded from rtPA were more likely to present with carotid artery stenosis (OR = 0.069, 95% CI 0.011-0.442), diabetes (OR = 0.604, 95% CI 0.366-0.997), higher total cholesterol (OR = 0.975, 95% CI 0.956-0.995), and history of alcohol use (OR = 0.438, 95% CI 0.232-0.828). Higher NIHSS score (OR = 1.051, 95% CI 1.017-1.086), higher triglycerides (OR = 1.004, 95% CI 1.001-1.006), and higher high-density lipoprotein (OR = 1.028, 95% CI 1.000-1.057) were associated with the inclusion for rtPA. Our findings reveal specific risk factors that contribute to the exclusion of patients with AIS with a combined effect of smoking and obesity from rtPA. These findings suggest the need to develop management strategies to improve the use of rtPA for obese patients with AIS with a history of smoking.

RESUMO

The delayed presentation of cancer patients to healthcare facilities for diagnosis is a pressing issue, as late-stage cancer cases are often more challenging to treat effectively. In low-resource settings, such as those with limited access to healthcare facilities, the impact of inadequate awareness of cancer signs and symptoms can be particularly severe. Therefore, this study aimed to evaluate public knowledge of cancer signs and symptoms and risk factors in the context of Jordan. This cross-sectional study was conducted among participants from all settings. Data was obtained from an Arabic version of the cancer awareness measure (CAM), which was answered online. It described demographic data and knowledge of cancer prevalence, age-related risk, signs, symptoms, and risk factors in recall and recognition-type questions. Participants (n = 1998) completed the questionnaire with a Median age of 35 and an interquartile range of 24. About half (n = 1070) thought that cancer is unrelated to age. Most participants identified breast cancer as the most common cancer among women (81%). Awareness of cancer signs/symptoms significantly differed in the level of knowledge in favor of females. The symptom "unexplained weight loss" was most commonly recognized (66.3%) and "persistent difficulty swallowing" the least (42.6%). As for risk factors, "smoking" was the most identified (76.9%) and "eating less than 5 portions of fruits and vegetables a day" was the least (19%), and "doing <30 minutes of moderate physical activity 5 times a week" as a close second least (19.95%). Females identified "smoking," "passive smoking," "HPV infection," and "having a close relative with cancer" as risk factors significantly more than males. Those with good economic status were more aware that smoking is a cancer risk factor by 1.51 times compared to those with poor economic status. To enhance early diagnosis and presentation in Jordan, there is a need for increased public awareness of the signs, symptoms, and risk factors of cancer. One effective strategy to achieve this goal is to conduct targeted public campaigns that cater to different population groups, such as the youth, to improve their understanding and ensure that the message resonates.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) induced by smoking poses a significant global health challenge. Recent findings highlight the crucial role of extracellular vesicles (EVs) in mediating miRNA regulatory networks across various diseases. This study utilizes the GEO database to uncover distinct expression patterns of miRNAs and mRNAs, offering a comprehensive understanding of the pathogenesis of smoking-induced COPD. This study aims to investigate the mechanisms by which extracellular vesicles (EVs) mediate the molecular network of miR-422a-SPP1 to delay the onset of COPD caused by smoking. METHODS: The smoking-related miRNA chip GSE38974-GPL7723 was obtained from the GEO database, and candidate miRs were retrieved from the Vesiclepedia database. Downstream target genes of the candidate miRs were predicted using mRNA chip GSE38974-GPL4133, TargetScan, miRWalk, and RNA22 databases. This prediction was integrated with COPD-related genes from the GeneCards database, downstream target genes predicted by online databases, and key genes identified in the core module of WGCNA analysis to obtain candidate genes. The candidate genes were subjected to KEGG functional enrichment analysis using the "clusterProfiler" package in R language, and a protein interaction network was constructed. In vitro experiments involved overexpressing miRNA or extracting extracellular vesicles from bronchial epithelial cell-derived exosomes, co-culturing them with myofibroblasts to observe changes in the expression levels of the miR-422a-SPP1-IL-17 A regulatory network, and assessing protein levels of fibroblast differentiation-related factors α-SMA and collagen I using Western blot analysis. RESULTS: The differential gene analysis of chip GSE38974-GPL7723 and the retrieval results from the Vesiclepedia database identified candidate miRs, specifically miR-422a. Subsequently, an intersection was taken among the prediction results from TargetScan, miRWalk, and RNA22 databases, the COPD-related gene retrieval results from GeneCards database, the WGCNA analysis results of chip GSE38974-GPL4133, and the differential gene analysis results. This intersection, combined with KEGG functional enrichment analysis, and protein-protein interaction analysis, led to the final screening of the target gene SPP1 and its upstream regulatory gene miR-422a. KEGG functional enrichment analysis of mRNAs correlated with SPP1 revealed the IL-17 signaling pathway involved. In vitro experiments demonstrated that miR-422a inhibition targets suppressed the expression of SPP1 in myofibroblasts, inhibiting differentiation phenotype. Bronchial epithelial cells, under cigarette smoke extract (CSE) stress, could compensate for myofibroblast differentiation phenotype by altering the content of miR-422a in their Extracellular Vesicles (EVs). CONCLUSION: The differential gene analysis of Chip GSE38974-GPL7723 and the retrieval results from the Vesiclepedia database identified candidate miRs, specifically miR-422a. Further analysis involved the intersection of predictions from TargetScan, miRWalk, and RNA22 databases, gene search on COPD-related genes from the GeneCards database, WGCNA analysis from Chip GSE38974-GPL4133, and differential gene analysis, combined with KEGG functional enrichment analysis and protein interaction analysis. Ultimately, the target gene SPP1 and its upstream regulatory gene miR-422a were selected. KEGG functional enrichment analysis on mRNAs correlated with SPP1 revealed the involvement of the IL-17 signaling pathway. In vitro experiments showed that miR-422a targeted inhibition suppressed the expression of SPP1 in myofibroblast cells, inhibiting differentiation phenotype. Furthermore, bronchial epithelial cells could compensate for myofibroblast differentiation phenotype under cigarette smoke extract (CSE) stress by altering the miR-422a content in their extracellular vesicles (EVs).

RESUMO

BACKGROUND: The relationship between smoking and the risk of acute respiratory distress syndrome (ARDS) has been recognized, but the conclusions have been inconsistent. This systematic review and meta-analysis investigated the association between smoking and ARDS risk in adults. METHODS: The PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched for eligible studies published from January 1, 2000, to December 31, 2023. We enrolled adult patients exhibiting clinical risk factors for ARDS and smoking condition. Outcomes were quantified using odds ratios (ORs) for binary variables and mean differences (MDs) for continuous variables, with a standard 95% confidence interval (CI). RESULTS: A total of 26 observational studies involving 36,995 patients were included. The meta-analysis revealed a significant association between smoking and an increased risk of ARDS (OR 1.67; 95% CI 1.33-2.08; P < 0.001). Further analysis revealed that the associations between patient-reported smoking history and ARDS occurrence were generally similar to the results of all the studies (OR 1.78; 95% CI 1.38-2.28; P < 0.001). In contrast, patients identified through the detection of tobacco metabolites (cotinine, a metabolite of nicotine, and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), a metabolite of tobacco products) showed no significant difference in ARDS risk (OR 1.19; 95% CI 0.69-2.05; P = 0.53). The smoking group was younger than the control group (MD - 7.15; 95% CI - 11.58 to - 2.72; P = 0.002). Subgroup analysis revealed that smoking notably elevated the incidence of ARDS with extrapulmonary etiologies (OR 1.85; 95% CI 1.43-2.38; P < 0.001). Publication bias did not affect the integrity of our conclusions. Sensitivity analysis further reinforced the reliability of our aggregated outcomes. CONCLUSIONS: There is a strong association between smoking and elevated ARDS risk. This emphasizes the need for thorough assessment of patients' smoking status, urging healthcare providers to vigilantly monitor individuals with a history of smoking, especially those with additional extrapulmonary risk factors for ARDS.

RESUMO

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.


Introduction: En France, les femmes enceintes reçoivent généralement des informations concernant leur grossesse sous forme écrite. Ces supports présentent des limites pour les femmes en situation de vulnérabilité, à plus haut risque d'avoir une littératie en santé limitée. Ainsi, les vidéos de sensibilisation sont devenues populaires et le dispositif de promotion de santé « Tuto'Tour de la grossesse ¼ a été créé, comprenant des vidéos sur le tabac. L'objectif de notre étude était d'évaluer l'acceptabilité, l'utilisabilité et l'accessibilité de deux vidéos sur le tabagisme chez les femmes enceintes fumeuses en situation de vulnérabilité. Méthodes: Nous avons conduit des entretiens semi-directifs auprès de ces femmes, en suivant une approche participative. Nous avons ensuite procédé à une analyse qualitative hybride, combinant une analyse fondée sur une trame conceptuelle et une analyse inductive. Résultats: Sur vingt participantes, neuf étaient séparées du père de l'enfant et neuf étaient sans emploi. Douze d'entre elles n'avaient pas atteint un niveau de formation équivalent au baccalauréat et sept avaient une langue maternelle autre que le français. Les vidéos ont été jugées acceptables, utilisables et accessibles pour les participantes. Des retours positifs ont été recueillis concernant l'efficacité des vidéos à induire un changement de comportement. Des pistes pour améliorer les vidéos ont été suggérées. Conclusions: D'autres études s'intéressent à des dispositifs similaires mais l'acceptabilité, l'utilisabilité et l'accessibilité n'ont pas été testées. Ces vidéos semblent avoir une influence sur deux des trois facteurs menant à un changement de comportement. Elles peuvent maintenant être testées à plus grande échelle dans une étude contrôlée randomisée.

RESUMO

Background: Adolescence is a critical phase of development characterized by numerous physical, psychological and social changes. During this stage, individuals may engage in experimentation and risky behavior, leading to increased vulnerability to addiction. This article aims to present the results of a survey based on the HBSC (Health Behavior in School-aged Children) surveillance model in a province of Southern Italy for primary and secondary school students. Methods: We conducted a prospective study from March 2020 to April 2023 through the administration of a questionnaire to students of the healthcare faculties of the University of Messina and primary and secondary school students, composed of 19 items and based on HBSC surveillance. Results: We collected a total of 664 questionnaires. We found that smoking habits increase with age: approximately 31% of secondary school students declare they are real smokers compared to 40% of HCP students. At least once, in the three study groups, students experienced alcohol consumption at different rates, with younger students having a greater propensity to drink than older students. Fortunately, in our sample, no middle school students had tried cannabis. At the same time there is a surprising decrease in gambling in all categories compared to national data. Conclusions: The presence of addictive behaviors in our sample was found to be widespread despite being in line with the national trend. Furthermore, we have observed a reduction in recent years which needs to be investigated to assess the reasons. Primary prevention is probably the main weapon in the hands of politicians and must be applied early in school and community settings to reduce prevalence.

RESUMO

BACKGROUND: Few studies have examined longitudinal changes in lifestyle-related factors and frailty. METHODS: We examined the association between individual lifestyle factors (exercise, diet, sleep, alcohol, smoking and body composition), their sum at baseline, their change over the 17-year follow-up and the rate of change in frailty index values using linear mixed models in a cohort of 2,000 participants aged 57-69 years at baseline. RESULTS: A higher number of healthy lifestyle-related factors at baseline was associated with lower levels of frailty but not with its rate of change from late midlife into old age. Participants who stopped exercising regularly (adjusted ß × Time = 0.19, 95%CI = 0.10, 0.27) and who began experiencing sleeping difficulties (adjusted ß × Time = 0.20, 95%CI = 0.10, 0.31) experienced more rapid increases in frailty from late midlife into old age. Conversely, those whose sleep improved (adjusted ß × Time = -0.10, 95%CI = -0.23, -0.01) showed a slower increase in frailty from late midlife onwards. Participants letting go of lifestyle-related factors (decline by 3+ factors vs. no change) became more frail faster from late midlife into old age (adjusted ß × Time = 0.16, 95% CI = 0.01, 0.30). CONCLUSIONS: Lifestyle-related differences in frailty were already evident in late midlife and persisted into old age. Adopting one new healthy lifestyle-related factor had a small impact on a slightly less steeply increasing level of frailty. Maintaining regular exercise and sleeping habits may help prevent more rapid increases in frailty.

RESUMO

BACKGROUND: Lung cancer is the leading cause of cancer-related death in the world. In contrast to many other cancers, a direct connection to modifiable lifestyle risk in the form of tobacco smoke has long been established. More than 50% of all smoking-related lung cancers occur in former smokers, 40% of which occur more than 15 years after smoking cessation. Despite extensive research, the molecular processes for persistent lung cancer risk remain unclear. We thus set out to examine whether risk stratification in the clinic and in the general population can be improved upon by the addition of genetic data and to explore the mechanisms of the persisting risk in former smokers. METHODS: We analysed transcriptomic data from accessible airway tissues of 487 subjects, including healthy volunteers and clinic patients of different smoking statuses. We developed a computational model to assess smoking-associated gene expression changes and their reversibility after smoking is stopped, comparing healthy subjects to clinic patients with and without lung cancer. RESULTS: We find persistent smoking-associated immune alterations to be a hallmark of the clinic patients. Integrating previous GWAS data using a transcriptional network approach, we demonstrate that the same immune- and interferon-related pathways are strongly enriched for genes linked to known genetic risk factors, demonstrating a causal relationship between immune alteration and lung cancer risk. Finally, we used accessible airway transcriptomic data to derive a non-invasive lung cancer risk classifier. CONCLUSIONS: Our results provide initial evidence for germline-mediated personalized smoke injury response and risk in the general population, with potential implications for managing long-term lung cancer incidence and mortality.

RESUMO

Background: Working memory is a crucial element of cognitive function. Previous cross-sectional studies have identified various determinants of working memory in children and adolescents. Nonetheless, no study has yet demonstrated the causal relationship of social determinants with working memory in adolescents. Objective: This study explores the causal link between the level of education, smoking, and other factors with adolescent's working memory. Methods: This study analyzed secondary data from waves 4 and 5 of the Indonesia Family Life Survey (IFLS), utilizing cross-lagged analysis in Jamovi version 2.4.8. The variables included working memory score, maternal education, household income, stress, educational level, smoking, urbanicity, and physical activity. These variables were extracted from IFLS waves 4 and 5, and each dependent variable in IFLS wave four was controlled by the same dependent variables in IFLS 5. Then, we used cross-lagged analysis to assess the causality between each dependent variable and a working memory score in IFLS wave 5. Result: The findings indicate that level of education had a positive impact on working memory in adolescents aged 15-18 years, with a Beta value of 0.18 (95% CI 0.81-0.2; p < 0.001). Smoking and age were negatively associated with working memory, with Beta values of -0.07 (95% CI -0.65 -0.04; p < 0.029) and - 0.10 (95% CI -0.25 -0.05; p < 0.003), respectively. No evidence was found for a significant correlation between poverty and adolescents's working memory. Conclusion: The findings indicate that increased education levels are associated with improved working memory in adolescents aged 15-18. At the same time, smoking has a negative impact on working memory in this age group.

RESUMO

BACKGROUND: Smoking remains the leading preventable cause of disease, disability, and death worldwide. Although physicians have high levels of health literacy with awareness of the consequences of smoking and their essential role in smoking cessation of patients, some physicians continue to smoke. Rates of smoking among Arab male physicians are high. This study aimed to gain insights into Arab male physician's perceptions of their own smoking behaviors and their professional role in health promotion. METHODS: Using purposive sampling, we recruited 25 Arab male physicians working in hospital and community clinic settings who currently smoke. Semi-structured, hour-long, interviews were held during January-June 2022. We then performed a thematic analysis of the interview data. RESULTS: The analysis revealed three categories, two sub-categories, and 15 emerging themes. The category 'Antecedents: prior to becoming a physician' revealed the themes: smoking experience during adolescence; social and ethnic culture; stress during medical studies; and on & off periods of quitting smoking. The category 'Physicians' perception of smoking' was sorted into two sub-categories: (1) Personal aspects, including the themes 'relaxation from stress', 'self-compensation', 'addiction', and 'enjoyable experience', and (2) Professional aspects, including the themes 'lack of knowledge about cessation', 'inadequate workplace support', 'motivation to consult patients', and 'awareness of their role as primary care physicians'. The category'Impacts' revealed the themes 'personal health and well-being', 'professional competence', and 'professional image in public'. CONCLUSIONS: This study provides an in-depth understanding of the personal, socio-cultural, and professional aspects of the phenomenon of Arab male smoking physicians from their perspective. Based on this information, we recommend developing programs that support and empower all physicians to cope better with their personal and professional stress as well as instituting programs that will provide all physicians with specific knowledge and skills related to smoking cessation. These programs should improve the ability of physicians to serve as positive role models for their patients for preventing and ceasing smoking, thus enhancing the image of the medical profession and, most importantly, improving the health of the public.

RESUMO

OBJECTIVE: To assess the return on investment (ROI) of the New York Tobacco Control Programme (NY TCP). SETTING: New York and other states of the USA. INTERVENTIONS: NY TCP. OUTCOMES: Smoking prevalence, smoking-attributable healthcare expenditures (SAEs), smoking-attributable mortality, years of life lost (YLL), the dollar value of YLL and the ROI for healthcare expenditures and mortality. DESIGN AND METHODS: We used a synthetic control method to estimate the effectiveness of NY TCP funding on smoking prevalence. The synthetic control method created a comparison group that best matched the adult smoking prevalence trend in New York state in the period prior to implementation of the NY TCP and compared smoking prevalence in the state to smoking prevalence in the synthetic control in the period after treatment (2001-2019). The synthetic control group represents what the trend in smoking prevalence in New York would have been had there been no tobacco control expenditures. The ROI was calculated as net savings for each outcome divided by net programme expenditures. RESULTS: Cumulative savings in SAE in New York from 2001 to 2019 amounted to US$13.2 billion. An estimated 41 771 smoking-attributable deaths (SADs) were averted in New York from 2001 to 2019, and an estimated 672 141 YLL averted as a result of NY TCP funding in the same period. From 2001 to 2019, the ROI for SAE in New York was approximately 14, the economic value ROI of the YLL due to SAD was nearly 145 and the combined ROI was almost 160. CONCLUSIONS: In this study, we found relatively large ROIs for the NY TCP, which suggests that the programme-which lowers SAE and saves lives-is an efficient use of public funds.

RESUMO

BACKGROUND: Observational studies have shown that smoking is related to the diffusing capacity of the lungs for carbon monoxide (DLCO) in individuals with idiopathic pulmonary fibrosis (IPF). Nevertheless, further investigation is needed to determine the causal effect between these two variables. Therefore, we conducted a study to investigate the causal relationship between smoking and DLCO in IPF patients using two-sample Mendelian randomization (MR) analysis. METHODS: Large-scale genome-wide association study (GWAS) datasets from individuals of European descent were analysed. These datasets included published lifetime smoking index (LSI) data for 462,690 participants and DLCO data for 975 IPF patients. The inverse-variance weighting (IVW) method was the main method used in our analysis. Sensitivity analyses were performed by MR‒Egger regression, Cochran's Q test, the leave-one-out test and the MR-PRESSO global test. RESULTS: A genetically predicted increase in LSI was associated with a decrease in DLCO in IPF patients [ORIVW = 0.54; 95% CI 0.32-0.93; P = 0.02]. CONCLUSIONS: Our study suggested that smoking is associated with a decrease in DLCO. Patients diagnosed with IPF should adopt an active and healthy lifestyle, especially by quitting smoking, which may be effective at slowing the progression of IPF.

RESUMO

BACKGROUND: The causal relationship between maternal smoking in pregnancy and reduced offspring birth weight is well established and is likely due to impaired placental function. However, observational studies have given conflicting results on the association between smoking and placental weight. We aimed to estimate the causal effect of newly pregnant mothers quitting smoking on their placental weight at the time of delivery. METHODS: We used one-sample Mendelian randomization, drawing data from the Avon Longitudinal Study of Parents and Children (ALSPAC) (N = 690 to 804) and the Norwegian Mother, Father and Child Cohort Study (MoBa) (N = 4267 to 4606). The sample size depends on the smoking definition used for different analyses. The analysis was performed in pre-pregnancy smokers only, due to the specific role of the single-nucleotide polymorphism (SNP) rs1051730 (CHRNA5 - CHRNA3 - CHRNB4) in affecting smoking cessation but not initiation. RESULTS: Fixed effect meta-analysis showed a 182 g [95%CI: 29,335] higher placental weight for pre-pregnancy smoking mothers who continued smoking at the beginning of pregnancy, compared with those who stopped smoking. Using the number of cigarettes smoked per day in the first trimester as the exposure, the causal effect on placental weight was 11 g [95%CI: 1,21] per cigarette per day. Similarly, smoking at the end of pregnancy was causally associated with higher placental weight. Using the residuals of birth weight regressed on placental weight as the outcome, we showed evidence of lower offspring birth weight relative to the placental weight, both for continuing smoking at the start of pregnancy as well as continuing smoking throughout pregnancy (change in z-score birth weight adjusted for z-score placental weight: -0.8 [95%CI: -1.6,-0.1]). CONCLUSION: Our results suggest that continued smoking during pregnancy causes higher placental weights.

RESUMO

INTRODUCTION: The global market of flavour capsule cigarettes (FCCs) has grown significantly over the past decade; however, prevalence data exist for only a few countries. This study examined prevalence and perceptions of FCCs among adults who smoke across five countries. METHODS: Cross-sectional data among adults who smoked cigarettes came from the International Tobacco Control Policy Evaluation Project Surveys-Brazil (2016/2017), Japan (2021), Republic of Korea (2021), Malaysia (2020) and Mexico (2021). FCCs use was measured based on reporting one's usual/current brand or favourite variety has flavour capsule(s). Perceptions of the harmfulness of one's usual brand versus other brands were compared between those who used capsules versus no capsules. Adjusted logistic regression models examined correlates of FCC use. RESULTS: There were substantial differences in the prevalence of FCC use among adults who smoke across the five countries: Mexico (50.3% in 2021), Republic of Korea (31.8% in 2021), Malaysia (26.5% in 2020), Japan (21.6% in 2021) and Brazil (6.7% in 2016/2017). Correlates of FCC use varied across countries. Capsule use was positively associated with being female in Japan and Mexico, younger age in Japan, Republic of Korea and Malaysia, high education in Brazil, Japan and Mexico, non-daily smoking in Republic of Korea, and having plans to quit in Japan and Republic of Korea. There was no consistent pattern of consumer perceptions of brand harmfulness. CONCLUSION: Our study documented the high prevalence of FCCs in some countries, pointing to the need to develop and implement regulatory strategies to control these attractive products.

RESUMO

Introduction: Menthol tobacco products have been marketed disproportionately to communities of color for decades. Methods: In Los Angeles County, California, a health marketing campaign, which used glossy visuals and attractive people in appealing poses, reminiscent of tobacco marketing tactics, was created and implemented to educate smokers on the health risks of using menthol cigarettes. The campaign encouraged smokers to make a quit attempt by offering access to free or low-cost resources through the Kick It California quitline and the LAQuits website (laquits.com). A survey tailored for public health professionals and community members from the approximately 382,000 people in the county who smoked menthol cigarettes and were exposed to their smoke (our primary audience) was administered to generate insights about this problem. Survey data were used to finesse the campaign creative materials prior to launch. Advertisement exposures, website visits, and quitline call volume were monitored and tabulated to assess the performance of the campaign. Results: At the conclusion of its initial run (February-April 2021), the "Done with Menthol" campaign had garnered more than 66 million impressions, received approximately 56,000 clicks on its various digital media platforms, and had click-through rates that surpassed industry benchmarks. The quitline call volume for African American and Latino subgroups were 1.9 and 1.8 times higher than the average inbound call volume for corresponding months during 2018 and 2019, respectively. In its second run (May-June 2023), the campaign garnered approximately 11 million additional impressions. Conclusions: Despite having a lower budget and fewer resources than the tobacco industry, the "Done with Menthol" campaign attained excellent reach and offered free, low-cost, and accessible resources to county residents interested in tobacco use cessation.

RESUMO

Thailand entered an aged society phase in 2000, with mild cognitive impairment (MCI) and frailty becoming prevalent among the older adult population. However, no studies have yet examined these issues specifically within rural communities. This study aims to explore the relationship between frailty and MCI among older adults in rural Thailand. It was a cross-sectional study conducted between December 2022 and June 2023. A questionnaire was administered by trained village health volunteers. The survey targeted older adults aged 60 years and above, residing in rural Chiang Mai, Thailand, with those having a history of dementia, depression, and brain injury being excluded from participation. Nine hundred eighty-four participants among the older adults were available for analysis. The mean age was 69.8 (SD 7.9) with 62.2% females (n = 612). The median frequency of exercise was three days (0-7). The prevalence of MCI and frailty among rural older adults in the community was 35.6% (n = 350) and 8% (n = 79), respectively. There were four factors associated with an increased risk of MCI, including age (aOR = 1.07, 95% CI 1.04-1.09, p < 0.001), smoking cigarettes (aOR 1.95, 95% CI 1.27-2.98, p = 0.002), feelings of loneliness (aOR 1.43, 95% CI 1.01-2.03, p = 0.043), and the presence of frailty (aOR 1.92, 95% CI 1.10-3.35, p = 0.022). There were two factors associated with a lower risk of MCI: a higher education level (aOR 0.90, 95% CI 0.86-0.94, p <0.001) and engaging in frequent exercise (aOR 0.9, 95% CI 0.86-0.95, p < 0.001). Frailty exhibited an association with an elevated risk of MCI among older adults in rural communities. Enhancing screening through health volunteers and primary healthcare professionals, coupled with bolstering community-driven health promotion initiatives, becomes imperative.

RESUMO

BACKGROUND: People experiencing homelessness co-occurring with substance use or offending ('severe and multiple disadvantage' SMD) often have high levels of poor oral health and related health behaviours (particularly, substance use, smoking, poor diet). This systematic review aimed to assess the effectiveness and cost-effectiveness of interventions in adults experiencing SMD to improve oral health and related health behaviours. METHODS AND FINDINGS: From inception to February 2023, five bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, and Scopus) and grey literature were searched. Two researchers independently screened the search results. Randomized controlled trials (RCTs), comparative studies and economic evaluations were included that reported outcomes on oral health and the related health behaviours. Risk of bias was assessed and results narratively synthesized. Meta-analyses were performed where appropriate. This review was registered with PROSPERO (reg. no: CRD42020202416). Thirty-eight studies were included (published between 1991 and 2023) with 34 studies reporting about effectiveness. Most studies reported on substance use (n = 30). Interventions with a combination of housing support with substance use and mental health support such as contingent work therapy appeared to show some reduction in substance use in SMD groups. However, meta-analyses showed no statistically significant results. Most studies had short periods of follow-up and high attrition rates. Only one study reported on oral health; none reported on diet. Three RCTs reported on smoking, of which one comprising nicotine replacement with contingency management showed improved smoking abstinence at 4 weeks compared to control. Five studies with economic evaluations provided some evidence that interventions such as Housing First and enhanced support could be cost-effective in reducing substance use. CONCLUSION: This review found that services such as housing combined with other healthcare services could be effective in improving health behaviours, particularly substance use, among SMD groups. Gaps in evidence also remain on oral health improvement, smoking, and diet. High quality studies on effectiveness with adequate power and retention are needed to address these significant health challenges in SMD populations.

RESUMO

OBJECTIVE: Acculturation stress can negatively impact Latinos immigrant mental and physical health related behaviors such as smoking. It is essential to have validated and updated instruments that allow the evaluation of acculturation stress on this population. This study aims to evaluate the psychometric properties of an abbreviated version of the Hispanic Stress Inventory Version 2 (HSI2) immigration scale among Latinos who smoke. METHODS: The study consisted of a secondary data analysis from a baseline assessment of Decídetexto, a mobile health (mHealth) smoking cessation randomized clinical trial. Of 457 Latinos included in the parent study, 352 immigrants who smoke were included. Construct validity was analyzed by completing a Pearson correlation coefficient matrix. Structural validity was analyzed using an Exploratory Factor Analysis (EFA). Cronbach alpha analysis was used to estimate the internal consistency of the items constituting a factor. RESULTS: The results included an abbreviated version of the HSI2 including 52 items. From the Pearson correlation coefficient matrix with a cutoff point of 0.4, 22 of the 52 items were excluded. From the Pearson correlation coefficient matrix with a cutoff point of 0.4, 22 items were excluded. Exploratory Factor Analysis (EFA) results in six factors extracted, explaining 69.1% of the variance. According to the EFA, two items were relocated in different factors from the original scale. The HSI2 30 items scale reflected excellent reliability with a Cronbach's alpha coefficient of 0.93. The six factors reflect acceptable to excellent reliability, ranging from 0.77-0.93 across factors. The median for the HSI2 total score was 34.00 (25-45) out of a possible total score of 150. CONCLUSION: Results confirmed acceptable psychometric properties of the HSI2 simplified 30-item version and provided a reliable and shorter measure of acculturation stress for Latinos groups. Having a valid and reduced measure of acculturation stress is the first step in understanding diverse ethnic groups of Latinos that are at higher risk of presenting health risk behaviors such as smoking. The present results provided the possibility of assessing the impact of acculturation stress among adults who smoke.
