RESUMEN
Objetivo: O estudo teve por objetivo avaliar o Programa Nacional de Controle do Tabagismo (PNCT) em Mato Grosso do Sul, taxas de cobertura, abandono, cessação, uso de medicamentos, rede de serviços de saúde e as razões pelas quais algumas Equipes de Saúde da Família de Campo Grande ainda não aderiram ao programa. Métodos: Trata-se de uma pesquisa descritiva, com abordagem quantitativa, baseada em dados primários e secundários sobre o PNCT em Mato Grosso do Sul. Os dados primários foram obtidos por meio de questionário aplicado aos profissionais das Equipes de Saúde da Família (ESF) de Campo Grande, sem oferta do programa e avaliados quanto à frequência e presença de correlação entre as variáveis analisadas utilizando V de Cramer e teste de χ2. Os dados secundários foram obtidos do consolidado do Instituto Nacional de Câncer José Alencar Gomes da Silva com os registros produzidos pelos serviços. Resultados: As taxas de adesão, efetividade e apoio farmacológico na capital e interior foram: 66,80 e 59,79%; 20,58 e 34,91%; 32,14 e 99,86%, respectivamente. A oferta do programa ocorreu em 49,37% municípios e 43,85% das Unidades Básicas de Saúde (UBS) estimadas. Houve correlações entre ser capacitado e implantar o programa; treinamento de ingresso e oferta na UBS. As dificuldades relatadas pelos profissionais foram a pandemia de COVID-19, a sobrecarga e/ou equipe pequena e/ou falta de tempo e a ausência de capacitação/treinamento. Conclusões: O PNCT em Mato Grosso do Sul apresenta baixa cobertura e oferta restrita na rede de saúde, além do desempenho mediano de assistência aos tabagistas. Evidencia-se a necessidade de investimento em capacitação/treinamento, prioritariamente para as ESF de Campo Grande, dando-lhes condições de responder às necessidades de promoção da saúde, reconhecendo o programa como de maior custo-efetividade.
Objective: The objective of this study was to evaluate the National Tobacco Control Program (PNCT) in Mato Grosso do Sul, coverage rates, dropout, cessation, use of medication, the health services network and the reasons why Family Health Teams in Campo Grande have not yet joined the program. Methods: This was a descriptive study with a quantitative approach, based on primary and secondary data on the PNCT in Mato Grosso do Sul. The primary data were obtained by means of a questionnaire administered to Family Health Teams (ESF) in Campo Grande, which did not offer the program and evaluated the frequency and presence of correlation between the variables analyzed using Cramer's V test and the χ2 test. The secondary data were obtained from the consolidated records of the José Alencar Gomes da Silva National Cancer Institute with the records produced by the services. Results: The rates of adherence, effectiveness and pharmacological support in the capital and interior were: 66.80 and 59.79%; 20.58 and 34.91%; and 32.14 and 99.86%, respectively. The program was offered in 49.37% of the municipalities and 43.85% of the Basic Health Units (UBS) estimated. There were correlations between being trained and implementing the program and entry training and provision in the UBS. The difficulties reported by professionals were the COVID-19 pandemic, overload and/or a small team and/or lack of time and the absence of training. Conclusions: The PNCT in Mato Grosso do Sul has low coverage and restricted supply in the health network, in addition to average performance in assisting smokers. There is a clear need to invest in capacitation/training, primarily for the ESF in Campo Grande, enabling them to respond to the needs of health promotion, recognizing the program as more cost-effective.

Background: Nicotine dependence, also known as tobacco dependence, is a common chronic disease and a major risk factor for chronic respiratory diseases. The present study was designed to determine the prevalence of nicotine dependence and its changes among smokers aged 40 years and older in China, to analyze the characteristics of nicotine dependence among smokers, and to provide a reference for smoking cessation interventions. Methods: The data were sourced from nationally representative large-sample surveys conducted during 2014-2015 and 2019-2020 in the Chinese population, covering 125 counties (districts) in 31 provinces, autonomous regions and municipalities. Variables related to smoking and nicotine dependence among residents ≥40 years old were collected in face-to-face interviews. A total of 20,062 and 18,975 daily smokers were included in the 2014-2015 and 2019-2020 surveys, respectively. The severity of nicotine dependence was evaluated according to the Fagerström Test for Nicotine Dependence and Heaviness of Smoking Index. The level and change in nicotine dependence among daily smokers aged ≥40 years were estimated using a complex weighted sampling design, and their influencing factors were analyzed. Results: Levels of nicotine dependence among daily smokers aged ≥40 years in China could be divided into very low, low, medium, high, and very high, accounting for 31.1%, 27.9%, 13.4%, 20.5%, and 7.1% of the total, respectively. The average Fagerström Test for Nicotine Dependence score was 3.9 (95% confidence interval [CI]: 3.8-4.0), with the prevalence of medium-high nicotine dependence being 41.0% (95% CI: 39.0-42.9%) and that of high and very high nicotine dependence being 27.6% (95% CI: 26.0-29.3%), both of which were significantly higher in men than in women (both P < 0.001). Among daily smokers, those with a low education level, age at smoking initiation <18 years, and with smoking duration of ≥20 years had a higher degree of nicotine dependence. In terms of geographic region, the level of medium-high nicotine dependence in South China was higher than in other areas, and the decline in the prevalence of high nicotine dependence was the greatest in Northwest China (P < 0.001). The prevalence of medium-high and high and very high nicotine dependence was significantly higher in men with chronic respiratory symptoms, chronic obstructive pulmonary disease (COPD), and/or chronic respiratory diseases than in men without these conditions (all P < 0.05). The prevalence of high and very high nicotine dependence in women with chronic respiratory symptoms and chronic respiratory diseases was significantly higher than that in women without these conditions (both P < 0.05). Compared with that during 2014-2015, the prevalence of high nicotine dependence among daily smokers decreased during 2019-2020 by 4.5 percentage points in the total population (P < 0.001) and by 4.8 percentage points in men (P < 0.001), with no significant change seen in women (P > 0.05). Additionally, the prevalence of high nicotine dependence in men with chronic respiratory symptoms and COPD decreased by 6.7 and 4.7 percentage points, respectively (P < 0.05), but showed no significant change in women with these conditions (P > 0.05). Multivariate logistic regression analysis showed that the risk of medium-high nicotine dependence was higher among daily smokers who were male; 50-59 years old; unmarried/divorced/widowed/separated; engaged in agriculture, forestry, husbandry, fishery and water conservancy; had a low education level; started smoking before the age of 18 years; and smoked for more than 20 years. Conclusions: The past few years have seen a slight decline in the prevalence of high (severe) nicotine dependence among smokers aged ≥40 years in China. However, 41.0% of daily smokers had medium-high nicotine dependence, and 27.6% had high or very high nicotine dependence, with notable differences in population and geographic distributions. Development of tailored interventions, optimization of smoking cessation service systems, and integration of smoking cessation into the management of chronic diseases will effectively reduce the burden of nicotine dependence in China.
RESUMEN
Smoking is by far one of the greatest public health threats and is recognized as an important predisposing factor for osteoporosis. Exposure to cigarette smoke (CS) has been reported to be associated with inflammation-associated diseases through the induction of pyroptosis. Nevertheless, the correlation between pyroptosis and bone loss induced by CS remains uninvestigated. Here, a mouse model of mainstream smoke exposure-induced osteoporosis was established. µCT, biomechanical testing, and immunohistochemical staining of bone tissue were used to assess the deleterious effects of CS on bone metabolism. In vitro, the effects of cigarette smoke extracts (CSE) on mouse primary bone marrow-derived mesenchymal stem cells (BMSCs) were tested by cell viability assays, gene and protein expression assays, and alizarin red staining. The utilization of the pyroptosis inhibitor MCC950 served to confirm the critical role of BMSCs pyroptosis in CS-induced osteoporosis. Our results indicated that exposure to mainstream smoke led to a notable decrease in the quantity of osteoblasts and hindered the process of osteogenic differentiation in mice. Additionally, there was a significant increase in the expression of pyroptosis-related proteins in the bone marrow. The inhibitory effects of CSE on cell viability and osteogenic differentiation of BMSCs were found to be dose-dependent in vitro. However, the presence of the pyroptosis inhibitor MCC950 significantly improved the impaired osteogenic differentiation and bone mineralization caused by CSE. These results highlight the crucial involvement of BMSCs pyroptosis in the development of bone loss induced by CS. In summary, the findings of this study provide novel evidence that CS exerts a detrimental effect on the process of osteogenesis in BMSCs through the induction of pyroptosis, ultimately leading to bone loss. Inhibition of pyroptosis effectively attenuated the toxicological effects of CS on BMSCs, providing a new target for preventing inflammatory osteoporosis.
RESUMEN
Background: South Africa has high tobacco-attributable mortality and a smoking prevalence of 32.5% in males and 25.6% in females. There are limited data on smoking prevalence and desire to quit in hospitalised patients, who have limited access to smoking cessation services. Objectives: To determine smoking prevalence and the extent of nicotine withdrawal symptoms, using a hospital-wide inpatient survey. Methods: A 1-day point prevalence survey was conducted at Groote Schuur Hospital, Cape Town. All wards except the haematology isolation, active labour and psychiatry lock-up wards were evaluated. Smoking status, withdrawal symptoms and desire to quit were established. Results: Smoking status was confirmed in 85.8% of inpatients (n=501/584), of whom 31.9% (n=160) were current smokers; 43.5% (n=101/232) of male and 21.9% (n=59/269) of female inpatients were smokers. Documentation and confirmation of smoking status was highest in the maternity wards (100%) and lowest in the surgical wards (79.6%) and intensive care units (70.0%). Smoking prevalence ranged from 47.6% in male surgical patients to 15.2% in maternity patients. Of the smokers, 54.5% reported being motivated to quit, with a median (interquartile range) Fagerström test for nicotine dependence score of 4 (2 - 6), and 31.4% reported moderate to severe cravings to smoke, highest in the surgical wards. Conclusion: Smoking prevalence was higher in hospitalised patients than in the local general population. Many inpatients were not interested in quitting; however, a third had significant nicotine withdrawal symptoms. All inpatients who are active smokers should be identified and given universal brief smoking cessation advice. Patients with severe withdrawal symptoms should be allowed to smoke outside, and nicotine withdrawal pharmacotherapy should be provided to those who are bedbound or express a desire to stop smoking during the current admission. Study synopsis: What the study adds. A single data point prevalence study of active smokers at Groote Schuur Hospital, Cape Town, was conducted. The prevalence of smoking was higher in the hospitalised patients than in the general community, but not all smokers were identified by the clinicians. Although symptoms of nicotine withdrawal were severe in some patients, motivation to quit smoking was not related to the degree of withdrawal being experienced. Many patients were not motivated to quit smoking.Implications of the findings. Better identification of inpatient smokers is required, and all should be given smoking cessation advice. Withdrawal symptoms can be severe in some patients, and those who are not interested in stopping smoking should allowed to smoke outside or be provided with nicotine withdrawal pharmacotherapy while in hospital. Those who are willing to quit should be supported as well as possible, including provision of nicotine replacement therapy or varenicline, and followed up after discharge as best practice.
RESUMEN
Objectives: Smoking is a preventable risk factor for morbidity and mortality in patients with liver disease. This study aims to explore the additional risks of smoking in the development of alcoholic liver disease (ALD), cirrhosis, and hepatocellular carcinoma (HCC) in high-risk drinkers. Methods: Data from the National Health Insurance Service, including claims and health check-up information spanning 2011 to 2017, were used. The overall alcohol consumption was calculated, and ALD was defined based on ICD-10 codes. High-risk drinking was defined as 7 or more drinks for men and 5 or more for women, twice weekly. Half of the high-risk drinkers were smokers, decreasing in men but stable at 20% for women. Results: ALD prevalence was 0.97% in high-risk drinkers and 1.09% in high-risk drinkers who smoked, higher than 0.16% in social drinkers (p < 0.001). ALD incidence over 3-years was highest in high-risk drinkers who smoked (2.35%), followed by high-risk drinkers (2.03%) and social drinkers (0.35%) (p < 0.001). Cirrhosis and HCC followed similar patterns, with prevalence and incidence was highest in drinkers who smoked. 3-year mortality was 0.65% in high-risk drinkers who smoked, compared to 0.50% in high-risk drinkers and 0.24% in social drinkers (p < 0.001). Smoking increased the incidence of ALD, cirrhosis, and HCC by 1.32, 1.53, and 1.53 times, respectively (all p < 0.001). Gender-specific analysis revealed higher risk ratios (RR) for women in ALD, alcoholic cirrhosis, and HCC, particularly among high-risk drinkers who smoked. Women showed significantly increased RR in ALD (6.08 to 12.38) compared to men (4.18 to 4.40), and similar trends were observed for cirrhosis and HCC. Conclusion: Smoking significantly heightens the risk of ALD, cirrhosis, and HCC, especially in women, among high-risk drinkers. This emphasizes the importance of smoking cessation, particularly for female patients with ALD.

BACKGROUND: Radon is a radioactive gas and a major risk factor for lung cancer (LC). METHODS: We investigated the dose-response relationship between radon and LC risk in the International Lung Cancer Consortium with 8927 cases and 5562 controls from Europe, North America, and Israel, conducted between 1992 and 2016. Spatial indoor radon exposure in the residential area (sIR) obtained from national surveys was linked to the participants' residential geolocation. Parametric linear and spline functions were fitted within a logistic regression framework. RESULTS: We observed a non-linear spatial-dose response relationship for sIR < 200 Bq/m3. The lowest risk was observed for areas of mean exposure of 58 Bq/m3 (95% CI: 56.1-59.2 Bq/m3). The relative risk of lung cancer increased to the same degree in areas averaging 25 Bq/m3 (OR = 1.31, 95% CI: 1.01-1.59) as in areas with a mean of 100 Bq/m3 (OR = 1.34, 95% CI: 1.20-1.45). The strongest association was observed for small cell lung cancer and the weakest for squamous cell carcinoma. A stronger association was also observed in men, but only at higher exposure levels. The non-linear association is primarily observed among the younger population (age < 69 years), but not in the older population, which can potentially represent different biological radiation responses. CONCLUSIONS: The sIR is useful as proxy of individual radon exposure in epidemiological studies on lung cancer. The usual assumption of a linear, no-threshold dose-response relationship, as can be made for individual radon exposures, may not be optimal for sIR values of less than 200 Bq/m3.

Despite the popularity of electronic cigarettes (e-cigs) among adolescent never-smokers and adult smokers seeking a less pernicious substitute for tobacco cigarettes, the long-term health impact of vaping is largely unknown. Like cigarette smoke, e-cig vapor contains harmful and potentially harmful compounds, although in fewer numbers and at substantially lower concentrations. Many of the same constituents of e-cig vapor and cigarette smoke induce epigenetic changes that can lead to the dysregulation of disease-related genes. MicroRNAs (MiRNAs) are key regulators of gene expression in health and disease states. Extensive research has shown that miRNAs play a prominent role in the regulation of genes involved in the pathogenesis of smoking-related diseases. However, the use of miRNAs for investigating the disease-causing potential of vaping has not been fully explored. This review article provides an overview of e-cigs as a highly consequential electronic nicotine delivery system, describes trends in e-cig use among adolescents and adults, and discusses the ongoing debate on the public health impact of vaping. Highlighting the significance of miRNAs in cell biology and disease, it summarizes the published and ongoing research on miRNAs in relation to gene regulation and disease pathogenesis in e-cig users and in vitro experimental settings. It identifies gaps in knowledge and priorities for future research while underscoring the need for empirical evidence that can inform the regulation of tobacco products to protect youth and promote public health.

BACKGROUND: Individuals living in rural communities experience substantial geographic and infrastructure barriers to attaining health equity in accessing tobacco use cessation treatment. Social media and other digital platforms offer promising avenues to improve access and overcome engagement challenges in tobacco cessation efforts. Research has also shown a positive correlation between faith-based involvement and a lower likelihood of smoking, which can be used to engage rural communities in these interventions. OBJECTIVE: This study aimed to develop and beta test a social intervention prototype using a Facebook (Meta Platforms, Inc) group specifically designed for rural smokers seeking evidence-based smoking cessation resources. METHODS: We designed a culturally aligned and faith-aligned Facebook group intervention, FaithCore, tailored to engage rural people who smoke in smoking cessation resources. Both intervention content and engagement strategies were guided by community-based participatory research principles. Given the intervention's focus on end users, that is, rural people who smoked, we conducted a beta test to assess any technical or usability issues of this intervention before any future trials for large-scale implementation. RESULTS: No critical beta test technical and usability issues were noted. Besides, the FaithCore intervention was helpful, easy to understand, and achieved its intended goals. Notably, 90% (9/10) of the participants reported that they tried quitting smoking, while 90% (9/10) reported using or seeking cessation resources discussed within the group. CONCLUSIONS: This study shows that social media platform with culturally aligned and faith-aligned content and engagement strategies delivered by trained moderators are promising for smoking cessation interventions in rural communities. Our future step is to conduct a large pilot trial to evaluate the intervention's effectiveness on smoking cessation outcomes.

BACKGROUND: Mitigating attrition is a key component to reduce selection bias in longitudinal randomized controlled trials (RCTs). Few studies of electronic nicotine delivery systems (ENDS) allow for the examination of long-term retention. This analysis explores the relationship between attrition, baseline measures, and condition assigned for a RCT involving ENDS differing in nicotine delivery over a 24-week intervention period. METHODS: Participants (N = 520) who smoked ≥10 cigarettes per day [CPD] for ≥1 year and reported interest in reducing but not quitting were randomized to 1 of 4 conditions: an ENDS containing 0, 8, or 36 mg/ml liquid nicotine (administered double-blind) or a cigarette-shaped plastic tube. Cox proportional hazards regression models were fit to examine attrition over time and predictors of attrition including baseline characteristics and condition. A stepwise approach was used to determine the final model; alpha was set at 0.05. RESULTS: Attrition did not differ significantly by condition (223/520), and most (69%) were lost-to-follow-up. Only age, education level, and household income were significantly predictive of attrition. For every additional year of age, attrition risk fell by 3%. Holding a bachelor's degree or higher was associated with reduced attrition risk. Those with the lowest income (<$10 K) were more likely to be withdrawn compared to those earning $10 K-39 K, and those with the highest income ($100 K+) were more likely to be withdrawn compared with the latter bracket and those earning $70-99 K. CONCLUSION: ENDS nicotine content did not drive differential attrition in this trial, and targeted retention efforts are needed for specific subgroups. Trial Registration #: NCT02342795.
RESUMEN
Tobacco smoking is a risk factor for countless diseases, and smoking relapse remains a major public health concern. Subjective reports of stress by smokers are a common theme for relapse, however, the role of objective stress-related biomarkers in predicting tobacco relapse risk has been less studied. The aim of this manuscript was to review existing literature on the connection between biomarkers of stress and smoking relapse. Overall, trends indicate that blunted hypothalamic-pituitary-adrenal (HPA) responses to acute stress, larger reductions in HPA biomarkers during the initial days of abstinence during cessation (compared to pre-cessation levels), and exaggerated autonomic responses to stress predict increased risk of relapse. In addition, successful cessation is followed by changes in stress biomarkers (e.g., reductions in cortisol and heart rate, HR). This review also identifies potential modifiers, such as methodological differences, biological sex, and chronic stress, to account for heterogeneity of findings within and across studies. In addition, we identify gaps in the literature and suggest future research directions focusing on the roles of genetics and gene expression as well as the influence of neurobiological mechanisms on stress and relapse risk. Future clinical implications of this research include identifying reliable indicators of relapse risk and the potential of pharmacotherapeutic treatments to target stress response systems to correct dysregulation and potentially reduce stress-related risk of relapse.
RESUMEN
Since the 1998 Master Settlement Agreement in the U.S., many studies have examined the associations between tobacco control policies and smoking; however, there is a need to comprehensively examine the impact of these policies on sociodemographic disparities in cigarette smoking. This protocol outlines a systematic review that seeks to fill this gap. Quantitative observational, experimental, and quasi-experimental studies are eligible for inclusion. Policies include cigarette taxes, smoke-free air laws, anti-tobacco media campaigns, and Tobacco 21 laws implemented in the U.S. Outcomes include cigarette smoking initiation, prevalence, and cessation among youth and adults. Sources to be searched include Clarivate BIOSIS, EBSCO CINAHL Plus, Cochrane Library, Ovid MEDLINE, PsycINFO, Sociological Abstracts, Clarivate Web of Science Core Collection, and the National Bureau of Economic Research. Included studies must be written in English. Two independent reviewers will screen and analyze relevant articles and then extract data on participants, context, methods, and key findings. Studies will be assessed using the Joanna Briggs Institute critical appraisal checklists and presented in 2 reviews: 1 youth focused (aged <18 years) and 1 adult focused (aged ≥18 years). The findings are intended to inform the creation of new and potentially more targeted tobacco control policies to improve health equity.
RESUMEN
Tobacco smoking, a significant public health concern globally, is associated with a rise in noncommunicable diseases (NCDs) and preventable deaths, with pronounced impacts in conflict zones like Gaza. A cross-sectional study, conducted in 2020, in Gaza focused on individuals over 40 years of age, aiming to identify predictors of tobacco use and its links to diseases like coronary artery disease (CAD), chronic lung disease (CLD), and stroke using regression analysis. The research, based on the Gaza NCD study data with 4576 participants and a 96.6% response rate, found an overall tobacco smoking prevalence of 19.4%, with higher rates among men. After adjusting for various factors, the study identified significant associations between cigarette smoking in men and adverse health outcomes, such as CAD and CLD, with adjusted odds ratios (OR) of 1.67, 95% CI (1.22-2.29) and 1.68, 95% CI (1.21-2.33) respectively. However, after adjusting for independent variables, shisha smoking in men showed no association with these health outcomes. The findings of this study could assist other researchers in designing interventions aimed at reducing smoking prevalence by utilizing the associated factors identified in our analysis, such as age, education level, physical activity, and body mass index among men in Gaza.

Introduction: Digital interventions present a scalable solution to overcome barriers to smoking cessation treatment, and changes in resting heart rate (HR) may offer a viable option for monitoring smoking status remotely. The goal of this study was to explore the acceptability of using smartphone cameras and activity trackers to measure heart rate for use in a smoking cessation intervention. Methods: Participants (N=410), most of whom identified as female (75.8 %) with mean age 38.3 years (SD 11.4), were recruited via the Smoke Free app. They rated the perceived comfort, convenience, and likelihood of using smartphone cameras and wrist-worn devices for HR monitoring as an objective measure of smoking abstinence. Wilcoxon signed-rank tests and Kruskal-Wallis tests assessed differences in acceptability across device types and whether the participant owned an activity tracker/smartwatch or smartphone. Results: Participants reported high levels of acceptability for both HR monitoring methods, with activity trackers/smartwatches rated more favorably in terms of comfort, convenience, and likelihood of use compared to smartphone cameras. Participants indicated a statistically significantly greater likelihood of using the activity tracker/smartwatch over the smartphone camera. Participants viewed the activity tracker/smartwatch as more acceptable than the smartphone camera (87.0% vs 50.0%). Conclusions: HR monitoring via smartphone cameras and wrist-worn devices was deemed acceptable among people interested in quitting smoking. Wrist-worn devices, in particular, were preferred, suggesting their potential as a scalable, user-friendly method for remotely monitoring smoking status. These findings support the need for further exploration and implementation of HR monitoring technology in smoking cessation research and interventions.
RESUMEN
Background: Supporting smoking cessation at pharmacies can be challenging owing to difficulties in recruiting smokers to participate in cessation programs, insufficient communication skills among pharmacists, and lack of knowledge and self-efficacy in successfully quitting smoking in Japan. Objective: This study evaluates the effectiveness of a smoking cessation training program on community pharmacists' knowledge, attitude, and self-efficacy in supporting smoking cessation. Methods: The study, conducted in Japanese pharmacies with 100 community pharmacists, employed a quasi-experimental design. Two online training programs were implemented. Participants completed a web-based survey assessing their knowledge, attitude, and self-efficacy in supporting smoking cessation before, immediately after, and 1 year after the training program. A two-way analysis of variance with a mixed model was used to examine score changes at each time point. Results: Total knowledge scores significantly increased between baseline and immediately after training and baseline and 1 year after training. The total attitude scores between baseline and immediately after training differed significantly. However, no differences were noted between baseline and 1 year after training. Total self-efficacy scores significantly increased at baseline, immediately after training, and between baseline and 1 year after training. Despite no significant interactions between the programs, there was a partial interaction effect on knowledge, with only the customized program having items whose knowledge levels improved after 1 year. Conclusion and Relevance: The training program improved community pharmacists' knowledge, attitude, and self-efficacy regarding smoking cessation support. The customized program must be reinforced to improve support performance and maintain attitude.
RESUMEN
CLINICAL RELEVANCE: Buerger's disease, being a systemic inflammatory vasculopathy, may present with ocular findings. BACKGROUND: This study aims to understand the potential role of optical coherence tomography and angiography findings in evaluating the course of Buerger's disease. METHODS: This was a prospective, cross-sectional study that included 25 patients with Buerger's disease (Group 1) and 51 healthy control participants, of whom 27 were smokers (Group 2) and 24 were non-smokers (Group 3). Following a detailed ophthalmic examination, optical coherence tomography and angiography measurements were conducted on participants. The values of macular superficial and deep capillary plexus, peripapillary capillary plexus vessel density measurements were taken into account from optical coherence tomography angiography measurements. Furthermore, measurements were taken for the parameters of the foveal avascular zone, including its area, perimeter and acircularity index. Additionally, the choriocapillaris flow area was assessed between radii of 1 mm, 2 mm, and 3 mm. RESULTS: In patients with Buerger's disease, the area and perimeter of the foveal avascular zone were higher than in both smoker and non-smoker healthy groups (p < 0.001 for all). The vessel densities in superficial capillary plexus were found to be lower in patients with Buerger's disease compared to both smokers and non-smokers in all regions except the parafovea (p < 0.05 for all). The radial peripapillary capillary plexus vessel densities in the whole retina and peripapillary region were lower than those in the non-smoker group (p < 0.001 and p = 0.008). The choriocapillaris flow areas in all three radius were lower in the smoker group than in the non-smoker group (1 mm, p = 0.01; 2 mm, p = 0.005; 3 mm, p = 0.011). CONCLUSIONS: Buerger's disease extends beyond the extremities, affecting vascular density and tissue perfusion in the optic disc and macula, making it a systemic condition.

BACKGROUND: Rosacea can be seen in many patients nowadays, and the related causes are complex. Despite a certain association between smoking and rosacea being reported by several studies, the actual causality has not been established for the possible bias and confounders. METHODS: We used Mendelian randomization (MR) to evaluate a potential causal effect of smoking on rosacea risk. Statistics on smoking and rosacea were obtained from the FinnGen project and Neale Lab Consortium. The causal association was assessed by multiple methods including inverse variance weighted (IVW), MR Egger, weighted median, and weighted mode. Furthermore, sensitivity analyses were also conducted to address pleiotropy, along with the leave-one-out method.R version 4.2.3 was applied for the analyses. RESULTS: The IVW estimation revealed that previous smoking has a deleterious effect on rosacea (odds ratio [OR] = 6.7729, 95% confidence interval [CI] = 1.5691-29.2356, p = 0.0104). By contrast, there was no statistically relationship between current smokers and rosacea (OR = 0.6180, 95% CI = 0.0605-6.3094, p = 0.6847). Results were similar in the analysis based on the weighted median method (previous smoking: OR = 8.6297, 95% CI = 1.0131-73.5071, p = 0.0486; current smoking: OR = 0.2896, 95% CI = 0.0106-7.9132, p = 0.4627). The stability of the causal effect estimates was supported by several sensitivity analyses and the leave-one-out method. CONCLUSION: Our MR study found support forrosacea risk and previous smoking. Although no evidence was found to increase the risk of rosacea in current smokers, to prevent various diseases associated with smoking, the public should be encouraged to avoid smoking at the very beginning.
RESUMEN
Background: Tobacco usage and obesity remain critical public health issues in the United States. This study examined the relationship between smoking behaviors, specifically-cigarettes per day (CPD) and motivations to smoke-and body mass index (BMI). We hypothesized that motivations related to food or stress, as well as a higher CPD, will be positively associated with BMI. Methodology: We analyzed the electronic medical records of 204 patients from the Johns Hopkins' Tobacco Treatment and Cancer Screening Clinic (TTCSC) between January and April 2022. Demographic information, smoking behavior, CPD, and motivations to smoke were recorded. Multiple linear regression analysis was performed. Results: We found no statistical significance between motivations to smoke, CPD, and BMI. However, the age at a patient's first visit to the TTCSC was negatively associated with BMI (B = -0.152, P < 0.001). Conclusions: Smoking behaviors were not significantly related to BMI in our sample. It is advisable for clinicians working in tobacco cessation clinics to consider the BMI of individuals who present for cessation services, especially for younger individuals who smoke. They may be more likely to have an elevated BMI at presentation.
RESUMEN
Abdominal pain in patients with significant alcohol use and smoking history presents diagnostic challenges due to overlapping clinical features of complications like acute cholecystitis and peptic ulcers. The unreliable physical examinations of intoxicated patients often complicate accurate diagnosis. We present a case of a 56-year-old male with a history of alcoholism and smoking, who presented to the emergency department with nonspecific abdominal pain. Initial imaging suggested cholecystitis, but due to the patient's intoxication, his physical examination was unreliable. During a laparoscopic cholecystectomy, a perforated prepyloric ulcer was unexpectedly discovered, sealed by the gallbladder. This case highlights the limitations of relying solely on imaging for diagnosing abdominal conditions in intoxicated patients. The intraoperative discovery of the perforated ulcer necessitated a shift in the surgical approach, emphasizing the need for flexibility in surgical planning and a high index of suspicion for other abdominal pathologies in patients with significant lifestyle risks. The successful management of this patient through adaptive surgical techniques and comprehensive postoperative care, including Helicobacter pylori eradication therapy, underscores the importance of maintaining a broad differential diagnosis and readiness to adapt surgical plans. This approach is essential for managing complex cases effectively, ensuring that both the immediate surgical issues and underlying causes are addressed to optimize recovery and prevent recurrence.
RESUMEN
INTRODUCTION: Many individuals change their smoking habits after cancer diagnosis. We aimed to evaluate the association of post-diagnosis smoking habit change with incident dementia in cancer survivors. METHODS: We identified 558,127 individuals who were diagnosed with cancer at age ≥ 20 and survived for ≥ 3 years. Participants were classified into four groups: (1) sustained non-smokers, (2) initiators/relapsers, (3) quitters, and (4) continuing smokers. Dementia risk in each group was assessed using a cause-specific Cox model. RESULTS: After cancer diagnosis, 2.3% of pre-diagnosis non-smokers initiated/relapsed into smoking, while 51.7% of pre-diagnosis smokers quit smoking. Compared to sustained non-smokers, multivariable-adjusted risk of dementia was 29% higher among initiators/relapsers, 11% higher among quitters, and 31% higher among continuing smokers. Compared to continuing smokers, the risk was 15% lower among quitters. DISCUSSION: In cancer survivors, smoking initiation/relapse was associated with increased risk of dementia, whereas smoking cessation was associated with decreased risk of dementia. HIGHLIGHTS: Approximately half of pre-diagnosis smokers quit smoking after a cancer diagnosis. Smoking cessation was associated with a 15% reduced risk of dementia. More than 2% of pre-diagnosis non-smokers initiated or relapsed into smoking after a cancer diagnosis. Smoking initiation/relapse was associated with a 29% elevated risk of dementia.
