Introduction The harmful effects of first and secondhand smoking are well-established. Smoke-free laws aim at protecting nonsmokers. This study aimed to assess the impact of the 2013 total ban on indoor smoking in Chile on hospitalizations and deaths of major cardiovascular events. Aims and Methods The logarithm of the monthly hospitalization and death rates, standardized by age for every 100 000 inhabitants, were estimated for ischemic heart disease, acute myocardial infarction, strokes, and a composite outcome of ischemic heart diseases (which includes acute myocardial infarction) and strokes. In addition, interrupted time series with synthetic control groups were used to assess changes in levels and trends after the intervention. Results The total ban on indoor smoking caused significant reductions in death rates for the three diseases studied for age groups above 20 years old. In addition, there were substantial decreases in the post-intervention hospitalization rates for ischemic heart disease: for the 20–44 age group, the decrease was 8.7% compared to the pre-intervention period (p < .01). In comparison, such a reduction was 4% (p < .01) for the ≥65 age group. For acute myocardial infarction, the decrease was 11.5% (p < .01) for the 20–44 age group, while for stroke, it was a 1.2% (p < .01) decrease for the total population. It is estimated that the smoking ban averted 15.6% of the deaths compared with the synthetic control groups. Conclusions The implementation of total smoke-free environments in Chile contributed to the reduction of mortality for main cardiovascular diseases. This study provides additional evidence of causality linking the policy to health outcomes. Implications The total indoor smoking ban significantly affected age-standardized hospitalization and deaths. The number of deaths averted by this policy is estimated at approximately 4758 and 5256 for IHD and stroke, respectively, during the 2013–2017 period (15.6% fewer deaths than predicted by the synthetic control groups). The study contributes to the body of evidence that supports total indoor smoking bans. [ABSTRACT FROM AUTHOR]

Simple Summary: Building on the idea of a germline oligogenic origin of lung cancer, we performed WES of DNA from patients' peripheral blood and their unaffected sibs. Filtering for rare variants and potentially damaging effects, we identified 40 deleterious variants mapping in genes previously associated with cancer exclusively identified in patients. Transcriptome profiling on both tumor and normal lung tissues revealed that, among the selected mutated genes, 16 variants mapping in 16 genes were either down- or upregulated in cancer specimens. Among the downregulated genes, 9 variants in 9 genes carried the mutated allele suggesting a loss of heterozygosity. Notably, the group of mutated genes was unique for each patient, pinpointing to a "private" oligogenic germline signature. In the era of precision medicine, this report emphasizes the importance of an "omic" approach to uncover an oligogenic germline signature underlying cancer development and identify suitable therapeutic targets. Lung cancer (LC) continues to be an important public health problem, being the most common form of cancer and a major cause of cancer deaths worldwide. Despite the great bulk of research to identify genetic susceptibility genes by genome-wide association studies, only few loci associated to nicotine dependence have been consistently replicated. Our previously published study in few phenotypically discordant sib-pairs identified a combination of germline truncating mutations in known cancer susceptibility genes in never-smoker early-onset LC patients, which does not present in their healthy sib. These results firstly demonstrated the presence of an oligogenic combination of disrupted cancer-predisposing genes in non-smokers patients, giving experimental support to a model of a "private genetic epidemiology". Here, we used a combination of whole-exome and RNA sequencing coupled with a discordant sib's model in a novel cohort of pairs of never-smokers early-onset LC patients and in their healthy sibs used as controls. We selected rare germline variants predicted as deleterious by CADD and SVM bioinformatics tools and absent in the healthy sib. Overall, we identified an average of 200 variants per patient, about 10 of which in cancer-predisposing genes. In most of them, RNA sequencing data reinforced the pathogenic role of the identified variants showing: (i) downregulation in LC tissue (indicating a "second hit" in tumor suppressor genes); (ii) upregulation in cancer tissue (likely oncogene); and (iii) downregulation in both normal and cancer tissue (indicating transcript instability). The combination of the two techniques demonstrates that each patient has an average of six (with a range from four to eight) private mutations with a functional effect in tumor-predisposing genes. The presence of a unique combination of disrupting events in the affected subjects may explain the absence of the familial clustering of non-small-cell lung cancer. In conclusion, these findings indicate that each patient has his/her own "predisposing signature" to cancer development and suggest the use of personalized therapeutic strategies in lung cancer.

This study was conducted in the Najaf Governorate, Iraq, to analyze biological samples from smokers and non-smokers. Blood serum, urine, hair, and nails as a biological sample at five age groups were chosen to determine alpha emitters (222Rn, 226Ra, 218Po, and 214Po) using a CR-39 detector. The results show that the average values of radon concentrations (Bq m−3) in blood serum, urine, hair, and nails for smokers were 54 ± 19, 63 ± 20, 33 ± 9, and 40 ± 12 respectively. While, the average values of radon concentrations (Bq m−3) in blood serum, urine, hair, and nails for non-smokers were 23 ± 6, 30 ± 6, 18 ± 5, and 20 ± 6 respectively. Age and smoking affect all alpha emitters, according to the study's conclusions and comparisons. Significantly higher alpha emitters were seen in smokers compared to non-smokers (p < 0.01). Alpha emitter levels were significantly variable among age groups (p < 0.01). In smokers, greater levels were significantly linked to exposure time (p < 0.01). Smokers had greater mean values of 222Rn, 226Ra, 218Po, and 214Po in biological samples than non-smokers. Thus, it may be said that cigarette smoking is used as a biomarker of the presence of alpha emitters. [ABSTRACT FROM AUTHOR]

Federally qualified health centers (FQHC) aim to improve cancer prevention by providing screening options and efforts to prevent harmful behavior. Patient portals are increasingly being used to deliver health promotion initiatives. However, little is known about patient portal activation rates in FQHC settings and the factors associated with activation. This study examined patient portal activation among FQHC patients and assessed correlations with demographic, clinical, and health service use variables. We analyzed electronic health record data from adults >18 years old with at least one appointment. Data were accessed from the electronic health records for patients seen between 1 September 2018 and 31 August 2022 (n = 40,852 patients). We used multivariate logistic regression models to examine the correlates of having an activated EPIC-supported MyChart patient portal account. One-third of patients had an activated MyChart portal account. Overall, 35% of patients with an activated account had read at least one portal message, 69% used the portal to schedule an appointment, and 90% viewed lab results. Demographic and clinical factors associated with activation included younger age, female sex, white race, English language, being partnered, privately insured, non-smoking, and diagnosed with a chronic disease. More frequent healthcare visits were also associated with an activated account. Whether or not a patient had an email address in the EHR yielded the strongest association with patient portal activation. Overall, 39% of patients did not have an email address; only 2% of those patients had activated their accounts, compared to 54% of those with an email address. Patient portal activation rates were modest and associated with demographic, clinical, and healthcare utilization factors. Patient portal usage to manage one's healthcare needs is increasing nationally. As such, FQHC clinics should enhance efforts to improve the uptake and usage of patient portals, including educational campaigns and eliminating email requirements for portal activation, to reinforce cancer prevention efforts.

Background: The nicotine in e-cigarette liquid can negatively impact periodontal tissues by altering the salivary pH and elevating cotinine levels. Thus, the study aimed to determine the periodontal parameters, salivary pH, and cotinine levels among cigarette, e-cigarette, and never-smokers. Methods: A total of 144 participants were recruited (48 cigarette smokers, 48 e-cigarette smokers, and 48 never-smokers). Clinical periodontal parameters, including plaque index (PI), gingival index (GI), periodontal probing pocket depth (PPD), and clinical attachment loss (CAL) were recorded, excluding third molars. The level of unstimulated whole salivary pH was measured using a portable pH meter and the levels of salivary cotinine were measured using Enzyme-Linked Immunosorbent Assay (ELISA). Results: Data were analysed statistically using analysis of variance. Mean scores of PPD, percentage of pocket depth ≥ 4 mm, and CAL (p < 0.05) were significantly higher among cigarette smokers than those in e-cigarette and never-smokers, while GI (p < 0.05) were significantly higher among e-cigarette smokers. The unstimulated salivary pH was more acidic among cigarette smokers (p < 0.05) and e-cigarette smokers (p < 0.05) than in never-smokers. The cotinine levels were higher among cigarette smokers (p < 0.05) and e-cigarette smokers (p < 0.05) than in never-smokers. Conclusions: Clinical periodontal parameters were poorer in cigarette smokers than in e-cigarette smokers and never-smokers. Meanwhile, cigarette and e-cigarette smokers have more acidic salivary pH and higher cotinine levels than in never-smokers. [ABSTRACT FROM AUTHOR]

Objective: Türkiye is the leading country that has been applying the MPOWER criteria of the World Health Organization for years. However, the prevalence of smoking among nurses appears to be high, according to the literature. Therefore, we aimed to determine the prevalence, addiction levels, and dynamics of tobacco smoking among nurses in Türkiye. Method: In this descriptive cross-sectional study, a questionnaire (prepared in cooperation with the "World Health Organization") and the Fagerström Test for Nicotine Dependence were administered to 529 nurses working at a tertiary-care university hospital in 2020. Logistic regression was performed to determine factors predicting smoking. Results: The prevalence of smoking among nurses was 32.7% (n = 173). The mean Fagerström test score indicated a "low dependence" level (score: 3 ± 2.6). Both results were higher for males. A relationship was found between trying smoking cigarette and hookah. Of the "current smokers" group, 102 (60.4%) stated that they wanted to quit smoking. Only 21 (27.6%) of the nurses who have tried to quit smoking thus far have received professional help. Conclusion: The prevalence of smoking among nurses working at a tertiary-care university hospital was relatively low compared to that among nurses in Türkiye. While females are normally expected to smoke less, the high prevalence of smoking among nurses (most of them female) raises the question of the professional basis of this situation. However, the low rate of receiving professional help reveals the lack of promotion and accessibility of smoking cessation outpatient clinics in the faculty environment. Finally, the perception that hookah is an alternative tobacco product leads to cigarette smoking. The good news was that nurses had a low dependency rate. [ABSTRACT FROM AUTHOR]

Background: The incidence of early-stage lung adenocarcinoma (ES-LUAD) is steadily increasing among non-smokers. Previous research has identified dysbiosis in the gut microbiota of patients with lung cancer. However, the local microbial profile of non-smokers with ES-LUAD remains largely unknown. In this study, we systematically characterized the local microbial community and its associated features to enable early intervention. Methods: A prospective collection of ES-LUAD samples (46 cases) and their corresponding normal tissues adjacent to the tumor (41 cases), along with normal lung tissue samples adjacent to pulmonary bullae in patients with spontaneous pneumothorax (42 cases), were subjected to ultra-deep metagenomic sequencing, host transcriptomic sequencing, and proteomic sequencing. The obtained omics data were subjected to both individual and integrated analysis using Spearman correlation coefficients. Results: We concurrently detected the presence of bacteria, fungi, and viruses in the lung tissues. The microbial profile of ES-LUAD exhibited similarities to NAT but demonstrated significant differences from the healthy controls (HCs), characterized by an overall reduction in species diversity. Patients with ES-LUAD exhibited local microbial dysbiosis, suggesting the potential pathogenicity of certain microbial species. Through multi-omics correlations, intricate local crosstalk between the host and local microbial communities was observed. Additionally, we identified a significant positive correlation (rho > 0.6) between Methyloversatilis discipulorum and GOLM1 at both the transcriptional and protein levels using multi-omics data. This correlated axis may be associated with prognosis. Finally, a diagnostic model composed of six bacterial markers successfully achieved precise differentiation between patients with ES-LUAD and HCs. Conclusions: Our study depicts the microbial spectrum in patients with ES-LUAD and provides evidence of alterations in lung microbiota and their interplay with the host, enhancing comprehension of the pathogenic mechanisms that underlie ES-LUAD. The specific model incorporating lung microbiota can serve as a potential diagnostic tool for distinguishing between ES-LUAD and HCs. [ABSTRACT FROM AUTHOR]

Objectives: To identify the characteristics of individuals transitioning from metabolically healthy obesity (MHO) to unhealthy obesity and the factors influencing the change. Design: This is a nationwide cohort study using data from the National Health Insurance Service in South Korea. Sample: Individuals with obesity but metabolically healthy in 2009 and 2010 and those still obese 4 years later were selected. Measurements: Sociodemographic, physical, metabolic, and health behavior variables were collected, and logistic regression was used to find an association with the transition. Results: We analyzed 1,564,467 individuals, observing significant differences in all variables and the transition from MHO to unhealthy obesity. Among males, the transition was associated with smoking and drinking positively and physical activity negatively. Among females, drinking demonstrated a negative correlation. Regardless of age, regular exercise was negatively associated with the transition for all individuals. Except for older adults, all age groups showed a positive correlation with smoking and drinking. Conclusions: Considering the significant factors in the transition, it is essential to develop and implement interventions varied by gender and age to delay and prevent the change in metabolic status. The necessity of developing interventions enables individuals to engage in regular exercise, regardless of age and gender. [ABSTRACT FROM AUTHOR]

Associations of fractional exhaled nitric oxide (FeNO) with airway wall remodeling and mucus plugs remain to be explored in smokers and nonsmokers with asthma. Ultra-high-resolution computed tomography (U-HRCT), which allows accurate structural quantification of airways >1 mm in diameter, was used in this study to examine whether higher FeNO was associated with thicker walls of the 3rd to 6th generation airways and mucus plugging in patients with asthma. The retrospective analyses included consecutive former smokers and nonsmokers with asthma who underwent U-HRCT in a hospital. The ratio of wall area to summed lumen and wall area was calculated as the wall area percent (WA%). Mucus plugging was visually scored. Ninety-seven patients with asthma (including 59 former smokers) were classified into low (<20 ppb), middle (20–35 ppb), and high (>35 ppb) FeNO groups (n = 24, 26, and 47). In analysis including all patients and subanalysis including nonsmokers or former smokers, WA% in the 6th generation airways was consistently higher in the high FeNO group than in the low FeNO group, whereas WA% in the 3rd to 5th generation airways was not. In multivariable models, WA% in the 6th generation airways and the rate of mucus plugging were higher in the high FeNO group than in the low FeNO group after adjusting for age, sex, body mass index, smoking status, lung volume, and allergic rhinitis presence. Higher FeNO may reflect the inflammation and remodeling of relatively peripheral airways in asthma in both former smokers and nonsmokers. [ABSTRACT FROM AUTHOR]

Introduction: Demographic and health factors are known to predict vaping. Less is known about psychological predictors of vaping uptake, particularly among non‐smoking adults using longitudinal designs. We aimed to model how psychological factors related to personality and mental health predicted the likelihood of vaping uptake over time in non‐smoking adults ages 18+ using longitudinal data. Methods: Longitudinal regression models utilised data from the 2018–2020 waves of the New Zealand Attitudes and Values Study to assess how the Big Five personality traits, mental distress and self‐control predicted who began vaping over time among non‐users (non‐vapers and non‐smokers), controlling for gender, age, ethnicity and economic deprivation. Results: Analyses included 36,309 adults overall (ages 18 to 99; M = 51.0). The number of non‐users who transitioned into current vaping was small (transitioned from 2018 to 2019, n = 147; 0.48%; 2019 to 2020, n = 189, 0.63%). Fully adjusted models showed that adults with higher mental distress (adjusted odds ratio [aOR] 1.43; 95% confidence interval [CI] 1.09–1.88), lower self‐control (aOR 0.79; 95% CI 0.69–0.89) and higher extraversion (aOR 1.09; 95% CI 1.06–1.13) were more likely to begin vaping at the next time point compared to adults who remained non‐users. Higher neuroticism and lower conscientiousness also predicted vaping uptake in initial models, but inclusion of mental distress and self‐control superseded these traits. Discussion and Conclusions: Psychological factors related to mental distress, impulse control and sociability predicted who was more likely to begin vaping as non‐smoking adults. Harm prevention interventions could target these factors to reduce vaping uptake in non‐smokers. [ABSTRACT FROM AUTHOR]

Objective: Although the adverse effects of smoking are well-established, evidence shows a longer survival rate following an acute myocardial infarction (MI) among smokers or the so-called "smoker's paradox". This study aimed to determine the impact of smoking on the one-year clinical outcomes of ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI) in a large registry of the Iranian population. Methods: A total of 3087 patients diagnosed with acute STEMI who underwent PPCI between 2013 and 2018 were enrolled in the study. Patients' smoking status was determined based on self-reported history and categorized into two groups: current smokers and non-smokers. Clinical and angiographic data were collected from the Tehran Heart Center (THC) registry. The primary outcome was one-year of major adverse cardiac and cerebrovascular events (MACCE). The effect of smoking on MACCE was evaluated using a Cox model. Results: From the study population, 1967 (63.7%) were non-smokers, and 1120 (36.3%) were current smokers. Non-smokers had higher rates of prior CABG (5.3%) as well as a higher history of co-morbidities, including a history of diabetes mellitus (46.0%), hypertension (52.7%) and hyperlipidemia (55.4%) than smokers (2.3%, 30.4%, 35.7%, and 49.8% respectively). Smokers had a higher reference vessel diameter than non-smokers (P=0.005). The unadjusted hazard ratios (HRs) for MACCE within one year were significantly lower in smokers than nonsmokers (0.73, 95% CI: [0.58,0.92]; P=0.009); however, after adjustment for confounders, the HRs for MACCE in smokers were similar to non-smokers (HR: 1.00, 95% CI: [0.73,1.38]). Conclusion: The study found that smoking had no significant impact on the one-year clinical outcomes of STEMI patients after PPCI in the Iranian population. This study is the first of its kind to assess the effect of smoking on STEMI patients in Iran and highlights the need for further research in this area. [ABSTRACT FROM AUTHOR]

The key to controlling tobacco use lies in preventing new smokers. Graphic health warnings (GHW) discourage smoking initiation, but their effectiveness depends, in part, on their design. To measure the effect of varying the design and location of GHW, which occupy 30% of the package, to discourage smoking initiation. Non-smokers young adults aged 18–21 years (n = 358) were recruited online and randomized to one of four experimental conditions, in a 2 (Color, yellow vs white) × 2 (Location, top vs. bottom) between subjects experimental design. GHWs located on top increase perceived message effectiveness, reduce pack appeal, and decrease purchase intention. Yellow color increases perceived message effectiveness and white color reduces pack appeal. Yellow warnings on top grabbed more attention. Results suggest that the yellow warning on top is the best combination for GHWs covering 30% of the pack. This combination increases perceived message effectiveness, decreases pack appeal, and is the most attention-grabbing. Health communication strategies that address these key considerations can contribute to the prevention of cigarette smoking-associated noncommunicable diseases. Competencies and sub-competencies in one area of responsibility, (V) Advocacy, were addressed. [ABSTRACT FROM AUTHOR]

Objective: The aims of this study were to determine the amount of smoking, the presence of back pain and the severity of pain, and to examine whether there was a relationship between smoking and back pain. Methods: The sample of the study consisted of 100 randomly selected students who were educated at university and had back pain. In individuals, a 22-question questionnaire and 21-question Beck Depression Scale were used, questioning parameters such as sociodemographic characteristics, physical activity levels, previous health problems, smoking status, as well as pain assessment tests. The results were analyzed by appropriate statistical methods. Results: Morning back pain was found to be higher in smokers compared to nonsmokers. (p <.05) BECK Depression Scale scores of smokers were found to be significantly different compared to nonsmokers (p =.00). In addition, it was observed that smokers needed more psychological medical support than nonsmokers (p =.00). Conclusions: This study revealed that although some significant results were found between smoking and some factors that cause back pain, there was no significant difference between smokers and nonsmokers.

Objective: Women smokers are overlooked because of their current low smoking rates compared to men smokers. However, smoking among women in developing countries, including Indonesia is increasing due to the weakening of social stigma that was previously said to prevent them from uptake cigarettes. The study aimed to explore the stigmatization of smoking women from women's perspectives. Methods: We interviewed 39 women—19 smokers and 20 nonsmokers aged 18 years old and above in Banda Aceh and Jakarta representing urban contexts. The transcribed interviews were analyzed using the self-categorization theory where women characterized identity at different levels of inclusiveness. Results: Our study found most participants perceived the social stigma of women smokers still exists. Women's viewpoints toward women smokers are situated between challenging and compromising women and their smoking conduct, illustrated by why they smoke, where they choose to smoke, and how the smokers look like. Conclusion: Women's perceptions and attitudes toward women smoking provide insights into how the remainder of social judgment can serve as a barrier to capturing accurate information about women smokers and solving smoking-related issues, particularly in developing countries, such as Indonesia.

Purpose: The present study assessed the efficacy of 0.12% chlorhexidine (CHX) and Salvadora persica-based mouthwashes (SPM) in reducing oral Candida carriage (OCC) and periodontal inflammation in cigarette smokers and non-smokers after non-surgical periodontal treatment (NSPT). Materials and Methods: Self-reported cigarette smokers and non-smokers with periodontal inflammation as well as nonsmokers with a healthy periodontal status were included. NSPT was performed in all participants. Based on the type of mouthwash, participants were randomly divided into three groups as follows: group 1: CHX; group 2: SPM; and group 3: distilled water (ddH2O) with mint flavour (control group). Clinical attachment loss (CAL), plaque index (PI), gingival index (GI), probing depth (PD), and marginal bone loss (MBL) were measured. Clinical periodontal parameters were re-assessed at a 6-week follow-up. Oral yeast samples were collected and identified using a concentrated oral-rinse culture technique and PCR, respectively. Clinical and laboratory-based investigations were done at baseline and after six weeks. Statistical significance was set at p < 0.05. Results: At baseline, PI, MBL, PD and CAL were comparable in all participants. None of the patients had periodontitis at baseline. Post-operatively, CHX and SPM were more effective in reducing PI (p < 0.01), GI (p < 0.01) and PD (p < 0.01) in nonsmokers than in the control group. The OCC was statistically significantly higher among smokers compared with nonsmokers at baseline. At the 6-month follow-up, CHX was more effective than SPM in reducing OCC in non-smokers (p < 0.01). At the 6-week follow-up, there was no difference in OCC among cigarette smokers regardless of the type of mouthwash prescribed postoperatively. Conclusion: In cigarette smokers and non-smokers, CHX and SPM are effective in reducing periodontal soft-tissue inflammation after NSPT. Post-operative use of CHX is more effective than SPM in reducing OCC. [ABSTRACT FROM AUTHOR]

Purpose: Individuals above the age of 65 are the first to be vaccinated. In this study, it was aimed to determine the health perceptions and vaccine complications of individuals over 65 years of age who recieved the covid-19 vaccine. Methods: The research is a descriptive and cross-sectional study. The sample consists of 151 adults over 65 who have received the Covid-19 vaccination. Individuals over the age of 65 who come to three different pharmacies in three distinct districts to buy medicine are considered participants. Results: The age of the participants was 72.42 ± 6,838, and their health perception score was 40,987 ± 5,878. The majority of them are male (51%), have had Sinovac (88.1%), are a primary school graduate (82.1%), live with their spouse (68.9%), are non-smokers (83.4%), have a chronic disease (96,0%), regularly take medication (96.7%), do not regularly get seasonal flu vaccine (78.8%), do not regularly use vitamins (92.7%), do not have joint pain (71.6%), and sleep for 7–9 h daily (50.4%). Scale scores were found as follows; control center 11.02 ± 2.66, precision 8.97 ± 2.41, importance of health 11.74 ± 2.64, self awareness 9.26 ± 2.03 health perception 40.99 ± 5.88. Conclusion: Those who received Sinovac, those with chronic disease, those who received routine influenza vaccination, those who took vitamin supplements, those who did not have joint pain, and those who had cough problems had higher health perception scores, and the difference was significant (p0.05). It will be critical to educate those over 65 about the vaccine's importance and adverse effects, as well as to boost their awareness in the appropriate manner. [ABSTRACT FROM AUTHOR]

Simple Summary: A family history of lung cancer has been reported to increase the risk of lung cancer development. Since a family history of lung cancer is generally regarded as an unmodifiable factor, understanding the relationship between a family history of lung cancer and the development of lung cancer is essential for establishing lung cancer screening strategies. However, previous studies on this issue did not consider various characteristics of study participants, such as age, sex, and smoking status, and there is an ongoing debate regarding which subgroups exhibit a higher genetic predisposition to lung cancer. Furthermore, no data are available on the impact of a family history of lung cancer on lung cancer risk in the general Korean population. Therefore, we aimed to investigate the association between a family history of lung cancer in first-degree relatives and lung cancer development through a comprehensive analysis of a large population-based cohort in Korea. Comprehensive analyses of the association between a family history of lung cancer and lung cancer risk are limited, especially in the Korean population. We used baseline data from the Korean Genome and Epidemiology Study, conducted between 2001 and 2013. This study enrolled 198,980 individuals. Lung cancer diagnoses and family histories were determined using questionnaires. Multivariable logistic regression analysis was performed to evaluate the effect of family history on the risk of lung cancer. Of 198,980 individuals, 6296 (3.2%) and 140 (0.1%) had a family history of lung cancer and lung cancer, respectively. Individuals with a family history of lung cancer in first-degree relatives (FDRs) had a higher risk of lung cancer development than those without (adjusted odds ratio [aOR] = 2.28, 95% confidence interval [CI] = 1.11–4.66). This was more pronounced in young individuals (<60 years) who had affected relatives diagnosed with lung cancer before the age of 60 years (aOR = 3.77, 95% CI = 1.19–11.88). In subgroup analyses, this association was more evident in women, never smokers, and young individuals. A family history of lung cancer, especially in FDRs, is a significant risk factor for lung cancer development in Korea. [ABSTRACT FROM AUTHOR]

Introduction Smoking is a cause of nonalcoholic fatty liver disease (NAFLD), but the dose–response relationship between secondhand smoke exposure (SHS) and NAFLD is unclear. This study sought to determine the relationship between SHS and NAFLD risk among adult nonsmokers in the United States. Aims and Methods Data from 7412 adult nonsmokers aged ≥20 years who participated in the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2016 were used in this study. SHS was defined as a nonsmoker with a serum cotinine concentration of 0.05–10.00 ng/mL. NAFLD was identified using the U.S. fatty liver index (USFLI), hepatic steatosis index (HSI), and fatty liver index (FLI). Weighted multivariable logistic regression and restricted cubic spline models were applied to evaluate the relationship between SHS and NAFLD risk. Results The participants had a weighted mean age of 49.2 years, and 55.5% were female. SHS was associated with NAFLD (odds ratio [OR] 1.22; 95% confidence interval CI: 1.05 to 1.42), showing a linear dose–response relationship (natural log of cotinine level: OR 1.10, 95% CI: 1.05 to 1.17). Sensitivity analyses using different NAFLD definitions (HSI: OR 1.21, 95% CI: 1.01 to 1.46; FLI: OR 1.26, 95% CI: 1.06 to 1.49), excluding participants taking hepatotoxic drugs, and propensity score-adjusted analysis yielded similar results. The association between SHS and NAFLD was consistent in analyses stratified by age, sex, and race/ethnicity. Conclusions Among this nationally representative sample of U.S. adults, SHS had a linear dose–response relationship with the risk of NAFLD, suggesting that measures to lower SHS might lower NAFLD risk. Implications This study assessed the association between secondhand smoke exposure and the risk of nonalcoholic fatty liver disease (NAFLD) using data from 7412 adult nonsmokers aged 20 years or older who participated in the United States NHANES between 2007 and 2016. Secondhand smoke exposure was measured using serum cotinine levels. Three different noninvasive indexes were used to measure NAFLD. Secondhand smoke exposure was associated with an increased risk of NAFLD, with a linear dose–response relationship. The results of sensitivity analyses and subgroup analyses were consistent.

Introduction The number of smokers worldwide increased greatly during the past decades and reached 1.14 billion in 2019, becoming a leading risk factor for human health. Tobacco smoking has wide effects on human genetics, epigenetics, transcriptome, and gut microbiome. Although many studies have revealed effects of smoking on host transcriptome, research on the relationship between smoking, host gene expression, and the gut microbiome is limited. Aims and Methods We first explored transcriptome and metagenome profile differences between smokers and nonsmokers. To evaluate the relationship between host gene expression and gut microbiome, we then applied bidirectional mediation analysis to infer causal relationships between smoking, gene expression, and gut microbes. Results Metagenome and transcriptome analyses revealed 71 differential species and 324 differential expressed genes between smokers and nonsmokers. With smoking as an exposure variable, we identified 272 significant causal relationships between gene expression and gut microbes, among which there were 247 genes that mediate the effect of smoking on gut microbes. Pathway-based enrichment analysis showed that these genes were significantly enriched in heme metabolic pathway, which mainly mediated the changes of Bacteroides finegoldii and Lachnospiraceae bacterium 9_1_43BFAA. Additionally, by performing metabolome data analysis in the Integrated Human Microbiome Project (iHMP) database, we verified the correlation between the intermediate products of the heme metabolism pathway (porphobilinogen, bilirubin, and biliverdin) and gut microbiome. Conclusions By investigating the bidirectional interaction between smoking-related host gene expression and gut microbes, this study provided evidence for the mediation of smoking on gut microbes through co-involvement or interaction of heme metabolism. Implications By comparing the metagenome and transcriptome sequencing profiles between 34 smokers and 33 age- and gender-matched nonsmokers, we are the first to reveal causal relationships among tobacco smoking, host gene expression, and gut microbes. These findings offer insight into how smoking affects gut microbes through host gene expression and metabolism, which highlights the importance of heme metabolism in modulating the effects of smoking on gut microbiome.

Purpose: Despite increasing use of cannabis, literature on perioperative effects is lagging. We compared active cannabis-smokers versus non-smokers and postoperative wound morbidity and reoperations following open abdominal wall reconstruction (AWR). Methods: Patients who underwent open, clean, AWR with transversus abdominis release and retromuscular synthetic mesh placement at our institution between January 2014 and May 2022 were identified using the Abdominal Core Health Quality Collaborative database. Active cannabis-smokers were 1:3 propensity matched to non-smokers based on demographics and comorbidities. Wound complications, 30 day morbidity, pain (PROMIS 3a-Pain Intensity), and hernia-specific quality of life (HerQles) were compared. Results: Seventy-two cannabis-smokers were matched to 216 non-smokers. SSO (18% vs 17% p = 0.86), SSI (11.1% vs 9.3%, p = 0.65), SSOPI (12% vs 12%, p = 0.92), and all postoperative complications (46% vs 43%, p = 0.63) were similar between cannabis-smokers and non-smokers. Reoperations were more common in the cannabis-smoker group (8.3% vs 2.8%, p = 0.041), driven by major wound complications (6.9% vs 3.2%, p = 0.004). No mesh excisions occurred. HerQles scores were similar at baseline (22 [11, 41] vs 35 [14, 55], p = 0.06), and were worse for cannabis-smokers compared to non-smokers at 30 days (30 [12, 50] vs 38 [20, 67], p = 0.032), but not significantly different at 1 year postoperatively (72 [53, 90] vs 78 [57, 92], p = 0.39). Pain scores were worse for cannabis-smokers compared to non-smokers at 30 days postoperatively (52 [46, 58] vs 49 [44, 54], p = 0.01), but there were no differences at 6 months or 1 year postoperatively (p > 0.05 for all). Conclusion: Cannabis smokers will likely experience similar complication rates after clean, open AWR, but should be counseled that despite similar wound complication rates, the severity of their wound complications may be greater than non-smokers.

Background: Studies indicated that smoking alters the response to anesthetics and alters the outcome of perioperative care. A full understanding of the impact of smoking cessation to enhance surgical outcomes is pertinent. Purpose: This research aimed to compare perioperative cardiopulmonary complications in smokers and non-smokers during elective surgery under general anesthesia. We aimed to determine the incidence of complications in patients with a history of smoking, identify those at an increased risk, and assess the relationship between smoking duration and complications Materials and Methods: A total of 100 patients, comprising 50 smokers and 50 non-smokers, were enrolled in the study. Various parameters, including heart rate increase during intubation, severe coughing, bronchospasm, oral secretions, oxygen desaturation, reintubation, opioid antagonist use, pulmonary edema, and other cardiopulmonary events, were assessed perioperatively. Statistical analysis involved both continuous and categorical variables. For continuous variables, the Student's t -test and the Mann–Whitney U test were used for normally and non-normally distributed data, respectively. For categorical variables, chi-squared tests were employed. Sub-group analysis assessed the influence of smoking duration on the measured parameters. Results: Smokers exhibited significantly higher incidences of severe coughing, heart rate elevation during intubation, and bronchospasm compared to non-smokers. Additionally, smokers experienced more pronounced oxygen desaturation throughout the perioperative period. Furthermore, a longer history of smoking was associated with an increased risk of complications, with individuals smoking for 10 or more years displaying a higher incidence of adverse events. Conclusion: Smokers, particularly those with extended smoking histories, are at an increased risk of cardiopulmonary complications during elective surgery under general anesthesia. Emphasizing preoperative optimization, meticulous airway management, and smoking cessation support is essential to mitigate these risks. The study underscores the significance of these measures for enhancing perioperative safety and calls for further research to explore the long-term impacts and patient satisfaction associated with these interventions. These steps are essential not only for perioperative care but also for long-term health benefits among this patient population. [ABSTRACT FROM AUTHOR]

Background: To examine the prevalence of smoking among medical faculty students in Turkey, and to explore the associations between smoking, depression, and other factors. Methods: This cross-sectional study was carried out among medical students in Konya, Turkey, from November 2018 to February 2019. The first section included eight questions pertaining to sociodemographic details. The second comprised nine questions addressing smoking and other harmful habits. The third section involved the Fagerstrom Test for Nicotine Dependence while the fourth was the Beck Depression Inventory (BDI). Results: The study was completed with a total of 1117 participants (90.2% of all students). In regard to smoking, 813 (72.78%) were non-smokers, 98 (8.77%) were ex-smokers, and 222 (19.87%) were active smokers. Notably, 16.29% of students (n = 182) had a high BDI score (≥17). Male sex, good economic status, depression diagnosis at any time in life, and alcohol use were independently associated with active smoking. Being a senior student and regular exercise were independently associated with a low (<17) BDI score, whereas depression diagnosis at any time in life and drug use were independently associated with high (≥17) BDI. Conclusions: Almost 20% of medical school students were active smokers, with about a 2.5-fold higher prevalence among males compared to females. There is a significant association between smoking frequency and symptoms of depression. Policies targeting modifiable risk factors can reduce smoking and depression among future physicians, which can have a strong impact on population-wide smoking. [ABSTRACT FROM AUTHOR]

CHRONIC obstructive pulmonary disease ,BIOMARKERS ,SPIROMETRY ,LEUCOCYTE elastase ,NON-smokers - Abstract
Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory condition with global implications. Accurate and timely diagnosis is critical; however, traditional diagnostic methods (based on spirometry) show limitations, prompting the search for predictive biomarkers and modern diagnostic techniques. This study explored the validation of COPD-related biomarkers (C-reactive protein, procalcitonin, neutrophil elastase, and alpha-1 antitrypsin) in saliva. A diverse cohort, including healthy non-smokers, healthy smokers, and COPD patients of Polish origin, underwent spirometry and marker analysis. The data correlated with clinical factors, revealing noteworthy relations. Firstly, salivary biomarker levels were compared with serum concentrations, demonstrating notable positive or negative correlations, depending on the factor. Further analysis within healthy individuals revealed associations between biomarker levels, spirometry, and clinical characteristics such as age, sex, and BMI. Next, COPD patients exhibited an enhanced concentration of biomarkers compared to healthy groups. Finally, the study introduced a breathing assessment survey, unveiling significant associations between self-perceived breathing and spirometric and tested parameters. Outcomes emphasized the relevance of subjective experiences in COPD research. In conclusion, this research underscored the potential of salivary biomarkers as diagnostic tools for COPD, offering a non-invasive and accessible alternative to traditional methods. The findings paved the way for improved modern diagnostic approaches. [ABSTRACT FROM AUTHOR]

Background: Periodontitis is a complex chronic inflammatory disease that is particularly associated with health-related conditions such as smoking, excessive drinking and depression. This research aimed to investigate the interaction between these lifestyles factors on periodontitis risk. Methods: This study included participants who participated in the National Health and Nutrition Examination Survey in the United States between 2009 and 2014. They had completed oral health-periodontal examination, Smoking-Cigarette Use Questionnaire, Alcohol Use Questionnaire, and Patient Health Questionnaire. Periodontal clinical attachment loss (CAL) of 3 mm or more and Patient Health Questionnaire-9 (PHQ-9) of 10 scores or more were used to identify periodontitis and depression, respectively. Daily alcohol consumption in the past year was classified into three levels: low (1 drink or less), moderate (between 1 and 3 drinks), and heavy drinking (4 drinks or more), while smoking was defined as having smoked at least 100 cigarettes in one's lifetime. Then, the logistic regression combined with interaction models were used to analyze the independent and combined effects of smoking, drinking and depression on periodontitis risk. Results: The results indicated a statistically significant multiplicative interaction between smoking and depression in relation to the development of periodontitis, both in the overall population (P = 0.03) and among male participants (P = 0.03). Furthermore, among individuals experiencing depression, smoking was found to significantly increase the prevalence of periodontitis by 129% in the younger age group compared to non-smokers (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.10 to 4.76). However, the interaction between smoking and alcohol consumption was only significant among females (P < 0.05). There was a dose-dependent relationship between drinking frequency and smoking on periodontitis prevalence. In the smoking population, occasional drinking (OR: 1.70; 95% CI: 1.22 to 2.37) and regular drinking (OR: 2.28; 95% CI: 1.68 to 3.11) significantly increased the prevalence of periodontitis compared to individuals without these two factors. Conclusion: These results suggested that there were interactive effects between smoking, drinking and depression on periodontitis risk and policies aimed at healthy behaviours and mental health may be beneficial for our oral health.

Objective: This study aimed to evaluate the association of serum zinc with periodontitis in non‐diabetics based on smoking status, using a representative sample of adults in the United States. Methods: A total of 1051 participants who underwent full‐mouth periodontal examination and serum zinc testing were enrolled from NHANES 2011 to 2014. The covariate‐adjusted association of serum zinc concentrations with periodontitis was explored using multivariable logistic regression, restricted cubic spines, and sensitivity analysis. Results: The mean age of the 1051 adults was 54.5 years, 59.37% were male, and 20.65% had periodontitis. Analysis of the results showed that serum zinc was associated with periodontitis. The overall adjusted odds of periodontitis were 9% (odds ratio [OR]: 0.91; 95% confidence interval [CI]: 0.83–1.00) and 14% (OR: 0.86; 95% CI: 0.75–0.98) for nonsmokers and smokers, respectively. Smokers with T3 serum zinc exhibited a 53% reduction in the fully adjusted odds of periodontitis (OR: 0.47; 95% CI: 0.23–0.96), when compared to the reference group (T1 serum zinc), with serum zinc as the categorical variable. Conclusions: Serum zinc levels were associated with the risk of periodontitis in non‐diabetic smokers but not non‐smokers. [ABSTRACT FROM AUTHOR]

OBJECTIVES Patients with severe coronary artery disease who undergo coronary artery bypass grafting consistently demonstrate that continued smoking after surgery increases late mortality rates. Smoking may exert its harmful effects through the ongoing chronic process of atherosclerotic progression both in the grafts and the native system. However, it is not clear whether cardiac mortality is primary and solely responsible for the inferior late survival of current smokers. METHODS In this retrospective analysis, we included all consecutive patients undergoing primary isolated coronary artery bypass surgery from 1 January 2000 to 30 September 2015 in an Academic Hospital in Northern Portugal. The predictive or independent variable was the patients' smoking history status, a categorical variable with 3 levels: non-smoker (the comparator), ex-smoker for >1 year (exposure 1) and current smoker (exposure 2). The primary end point was long-term all-cause mortality. Secondary outcomes were long-term cause-specific mortality (cardiovascular and noncardiovascular). We fitted overall and Fine and Gray subdistribution hazard models. RESULTS We identified 5242 eligible patients. Follow-up was 99.7% complete (with 17 patients lost to follow-up). The median follow-up time was 12.79 years (interquartile range, 9.51–16.60). Throughout the study, there were 2049 deaths (39.1%): 877 from cardiovascular causes (16.7%), 727 from noncardiovascular causes (13.9%) and 445 from unknown causes (8.5%). Ex-smokers had an identical long-term survival than non-smokers [hazard ratio (HR) 0.99; 95% confidence interval (CI) 0.88, 1.12; P = 0.899]. Conversely, current smokers had a 24% increase in late mortality risk (HR 1.24; 95% CI 1.07, 1.44; P = 0.004) as compared to non-smokers. While the current smoker status increased the relative incidence of noncardiac death by 61% (HR 1.61; 95% CI 1.27, 2.05, P < 0.001), it did confer a 25% reduction in the relative incidence of cardiac death (HR 0.75; 95% CI 0.59, 0.97; P = 0.025). CONCLUSIONS Whereas ex-smokers have an identical long-term survival to non-smokers, current smokers exhibit an increase in late all-cause mortality risk at the expense of an increased relative incidence of noncardiac death. By subtracting the inciting risk factor, smoking cessation reduces the relative incidence of cardiac death. [ABSTRACT FROM AUTHOR]

Introduction: Studies evaluating smoking and periodontal status show controversial results regarding the impact on oral health‐related quality of life (OHRQol). The aim was to evaluate the association between OHRQol and periodontal status in patients according to their smoking habit. Methods: Cross‐sectional study with a total of 100 patients (31.44 ± 8.50 years, 55% females) answered the short version of Oral Health Impact Profile (OHIP‐14) and underwent a periodontal examination. Associations between periodontal status and total mean OHIP‐14 scores related with smoking habit were analysed with Kruskal–Wallis test. Results: Mean percentage of sites with Bleeding on Probing (BOP), Clinical Attachment Loss (CAL) and Number of Teeth were significantly different between current smokers (n = 53) and never (n = 40) or former smokers (n = 7; p < 0.05). There was no significant difference for Periodontal Probing Depth (PPD) in relation to smoking status. A total mean OHIP‐14 score of 13.07 was observed for the entire sample. The corresponding total mean OHIP‐14 scores, for current smokers, never smokers and former smokers, were 15, 10 and 13 (p = 0.280), respectively. The domains social disability and handicap of the OHIP‐14 were worse in current smokers (p = 0.028 and p = 0.026, respectively). Conclusion: Current smoking was associated with a negative influence on OHRQoL in the domain of social disability and handicap. In addition, smokers have worse periodontal status, related to less BOP, greater CAL and fewer teeth than never and former smokers. [ABSTRACT FROM AUTHOR]

Background: Large population-based prospective studies are necessary to provide clarification on the associations of panoramic secondhand smoking burden, including prenatal and postnatal secondhand smoke (SHS) exposure, with the risk of developing dementia. Methods: Our study comprised a sample of 353,756 dementia-free individuals from the UK Biobank who were nonsmokers had data on the exposure of maternal smoking as well as SHS exposure in daily life, which was quantified in terms of hours per week (h/week) and whether they lived with household smokers. Multivariable Cox regression models were utilized to analyze the independent and joint associations of maternal smoking and daily life SHS exposure with dementia risk. Results: During a median follow-up of 11.8 years, 4,113 participants developed dementia. Compared with those who lived in the environment without smokers, multivariable-adjusted hazard ratios (HRs) (95% CIs) were 1.11 (1.02, 1.20) and 1.31 (1.13, 1.52) for those who exposed to SHS for >0 but ≤4 h/week and >4 h/week, respectively, and was 1.25 (1.13, 1.39) for those who lived with smokers in the household. A positive history of maternal smoking was associated with a modestly higher risk of dementia (HR = 1.07; 95% CI: 1.01, 1.15). Furthermore, compared with participants with neither history of maternal smoking nor exposure to SHS, a particularly higher risk of dementia was observed among those with both exposures (HR = 1.48; 95% CI: 1.18, 1.86). Additionally, the HR (95% CI) was 1.32 (1.10, 1.59) when comparing participants with a history of maternal smoking who lived with smokers in their households with those who had neither exposures. Conclusions: Having a history of maternal smoking, longer exposure to SHS, and living with smokers in the household were each associated with an increased risk of developing dementia. Individuals who were simultaneously exposed to maternal smoking and SHS or lived with household smokers had a particularly higher dementia risk. [ABSTRACT FROM AUTHOR]

Objective: Although some studies have linked smoking to mortality after out-of-hospital cardiac arrests (OHCAs), data regarding smoking and mortality after OHCAs have not yet been discussed in a meta-analysis. Thus, this study conducted this systematic review to clarify the association. Methods: The study searched Medline-PubMed, Web of Science, Embase and Cochrane libraries between January 1972 and July 2022 for studies that evaluated the association between smoking and mortality after OHCAs. Studies that reportedly showed relative risk estimates with 95% confidence intervals (CIs) were included. Results: Incorporating a collective of five studies comprising 2477 participants, the analysis revealed a lower mortality risk among smokers in the aftermath of OHCAs compared with non-smokers (odds ratio: 0.77; 95% CI 0.61–0.96; P < 0.05). Egger's test showed no publication bias in the relationship between smoking and mortality after OHCAs. Conclusions: After experiencing OHCAs, smokers had lower mortality than non-smokers. However, due to the lack of data, this 'smoker's paradox' still needs other covariate effects and further studies to be considered valid. [ABSTRACT FROM AUTHOR]

Background: To compare presence and levels of serum cytokines in smokers and non-smokers with periodontitis following periodontal therapy. Methods: Thirty heavy smokers and 30 non-smokers with stage III or IV periodontitis were included in this prospective cohort study. Clinical data and blood serum were collected at baseline (T0), after step I-III (T1), and after 12 months step IV periodontal therapy (T2). Cytokine IL-1β, IL-6, IL-8, TNF-α, IL-10, and IP-10 levels were measured using multiplex kit Bio-Plex Human Pro™ Assay. Linear regression models with cluster robust variance estimates to adjust for repeated observations were used to test intra- and intergroup levels for each marker, IL-6 and IL-8 defined as primary outcomes. Results: Clinical outcomes improved in both groups following therapy (p < 0.05). IL-6 levels increased with 75.0% from T0-T2 among smokers (p = 0.004). No significant intra- or intergroup differences were observed for IL-8. Higher levels of TNF-α (44.1%) and IL-10 (50.6%) were detected in smokers compared with non-smokers at T1 (p = 0.007 and p = 0.037, respectively). From T1-T2, differences in mean change over time for levels of TNF-α and IL-10 were observed in smokers compared with non-smokers (p = 0.005 and p = 0.008, respectively). Conclusion: Upregulated levels of serum cytokines in smokers indicate a systemic effect of smoking following periodontal therapy. Differences in cytokine levels between smokers and non-smokers demonstrate a smoking induced modulation of specific systemic immunological responses in patients with severe periodontitis.

Introduction: The minimal clinically important difference (MCID) is a valuable tool for patient-based outcome analysis, for which limited data is available in the literature, especially after arthroscopic rotator cuff repair (ARCR). Although several studies have reported MCID after ARCR, few have studied the impact of various clinical factors such as Diabetes, pseudoparalysis, type of cuff repair, and retear over MCID. This study attempts to determine the MCID in shoulder functional scores after ARCR and the impact of various factors on MCID. Methods: 144 patients undergoing ARCR were prospectively evaluated at six and 12 months by ASES and UCLA scores. MCID for American Shoulder and Elbow Surgeons (ASES) and the University of California and Los Angeles (UCLA) scores were calculated using an anchor-based and distribution-based approach. MCID was also calculated for diabetic and non-diabetic patients, smokers vs. non-smokers, presence or absence of pseudoparalysis, type of cuff repair (single row vs. suture bridge), and presence of retears. Uni- and multivariate analysis was performed to identify factors affecting the MCID of both scores. Results: Mean MCID for ASES score was 13.3 and 16.6 using an anchor-based and distribution-based approach, respectively. For the UCLA score, the mean MCID was 10.0 and 12.6 by anchor-based and 12.6 by distribution-based approach, respectively. Patients with higher pre-operative ASES scores demonstrated lower MCID values. No significant difference was observed in MCID scores of diabetic vs. non-diabetic patients, smoker vs. non-smoker, patients with or without pseudoparalysis, and type of cuff repair. The age, gender, and presence of retear did not affect MCID values. Conclusion: This study establishes the MCID values of ASES and UCLA scores for rotator cuff repair by anchor and distribution methods. No patient or surgical factors appear to affect the MCID except pre-operative ASES scores. Study design: Prospective cohort, Level II. [ABSTRACT FROM AUTHOR]

According to the association between increased micronuclei (MNi) level in reproductive age women and increased risk of congenital abnormalities, we aimed in this study to find the contribution of WTS to women's health in apparently healthy young cases by comparing the variability of MN values in water pipe smokers and non-smokers. Finding the associations between MNi levels and demographic, socioeconomic, reproductive, and lifestyle factors was the secondary scope of this study. This cross-sectional case-control study was performed on 30 premenopausal women (15 cases and 15 controls) who lived in Tehran, according to our inclusion criteria. The mean MN frequency among waterpipe smokers was 28.53± 7.462, whereas the same parameter in the control group was 6.53 + 3.24 (p= 0.001). Non-parametric tests revealed a significant association between MNi and frequency of waterpipe smoking (p = 0.001), age of starting waterpipe smoking (p = 0.003), concurrent use of alcoholic drinks (p= 0.004), and secondhand smoking (p =0.001). In the context of heavy environmental pollution in Tehran, significantly higher MNi frequencies and decreased genomic health in waterpipe smoker women in reproductive age may predispose them to an increased risk of harmful reproductive outcomes. These findings emerge from governmental and non-governmental biomonitoring programs in high-risk women to concern more on unhealthy lifestyles and environmental pollution. [ABSTRACT FROM AUTHOR]

Background: The recent increase in workload and stress experienced by healthcare workers (HCW) is a significant global concern. Mindfulness enables one to be aware of emotions, thoughts, and present moment experiences. Objectives: The primary objective of this research is to investigate the correlates between smoking, occupational stress, and mindful awareness levels, among HCWs within the private healthcare sector. This study was conducted at a tertiary-level university-affiliated hospital in Istanbul between January – February 2023. 208 HCW participated, yielding a response rate of 20%. The participants were requested to complete a 61-item questionnaire consisting of demographics, General Work Stress Scale(GWS), Mindful Attention Awareness Scale (MAAS) and Test to Assess the Psychological Dependence on Smoking (TAPDS). Results: Smokers had significantly higher levels of mean GWS scores than nonsmokers. The mean MAAS scores of smokers were the lowest in the group with the highest scores of psychological dependence; it was highest in the group with the lowest scores. A negative correlation was found between general work stress and mindful awareness levels and between psychological dependence on smoking and mindfulness levels. HCWs aged 45 and older had significantly lower general stress than others. Conclusion: This study showed that the general work stress levels of smoker HCWs were higher than those of nonsmokers. Mindful awareness level was the lowest in the group, with the highest scores in psychological dependence on smoking. There was a negative correlation between psychological dependence on smoking and both work stress and mindful awareness levels. This study demonstrated that high work stress and low mindful awareness levels are not only related to each other but also to high psychological dependence on smoking. [ABSTRACT FROM AUTHOR]

Objective: Staccato® alprazolam is a single‐use, drug–device combination delivering alprazolam to the deep lung that is being evaluated as treatment for rapid and early seizure termination. This article reports pharmacokinetic (PK) data from two phase 1 studies of Staccato alprazolam in healthy adult participants. Methods: The smoker study (EPK‐002/NCT03516305) was an open‐label, nonrandomized, single‐dose, PK study in smokers and nonsmokers aged 21–50 years, administered a single inhaled dose of 1 mg Staccato alprazolam. The ethnobridging study (UP0101/NCT04782388) was a double‐blind, placebo‐controlled study in Japanese, Chinese, and Caucasian participants aged 18–55 years randomized 4:1 to a single inhaled dose of Staccato alprazolam 2 mg or Staccato placebo. Results: In the smoker study, 36 participants (18 smokers, 18 nonsmokers) were enrolled and received Staccato alprazolam. Following Staccato administration, alprazolam was rapidly absorbed, with a median time to peak drug plasma concentration (Tmax) of 2 min in both smokers (range = 2–30 min) and nonsmokers (range = 2–60 min). Staccato alprazolam was rapidly absorbed to a similar extent in both smokers and nonsmokers. The most commonly reported treatment‐emergent adverse events (TEAEs) were somnolence and dizziness. In the ethnobridging study, 10 participants each of Japanese, Chinese, and Caucasian ethnicities were randomized 4:1 to Staccato alprazolam or Staccato placebo. Following Staccato administration, alprazolam was rapidly absorbed and distributed, with a median Tmax of 1.5–2 min in Japanese (range = 1–2 min), Chinese (range = 1–34 min), and Caucasian (range = 1–120 min) participants. Somnolence and sedation were the most commonly reported TEAEs. In both studies, there were no deaths, and no participants reported serious or severe TEAEs, or discontinued due to TEAEs. Significance: Alprazolam was rapidly absorbed, and therapeutic drug levels were achieved within 2 min postdose when administered to the lung with the Staccato device. Staccato alprazolam was generally well tolerated and displayed a safety profile consistent with that known from other alprazolam applications. No new safety signals were identified.

- Abstract
Introduction Cigarette smoke increases peripheral white blood cell (WBC) count. However, the dose-dependent association between smoking and C-reactive protein (CRP), an important inflammatory marker, has been reported as inconsistent. Aims and Methods Here, we evaluated the associations between smoking and CRP using both smoking questionnaires and urine cotinine as exposure markers. The Korea National Health and Nutrition Examination Survey data were used for analyzing the associations. Multiple regression analyses were performed to examine the associations between cigarette smoke exposure, as assessed by questionnaires and urine cotinine, and health effects, as measured by CRP and WBC count, controlling for potential confounders. The confounders, including age, sex, body mass index, blood pressure, cholesterol, glucose, alanine aminotransferase, and uric acid, were selected a priori based on the literature. Results A total of 11 435 participants were included for analysis. For the exposure-response relationship, the results indicated a significant increase in CRP levels in male smokers compared to male nonsmokers (p = .002), whereas no significant increase was found in female smokers compared to female nonsmokers (p = .680). For the dose–response relationship, a significant positive association was observed between urine cotinine and CRP in male smokers (p = .018), whereas no significant association was found in female smokers (p = .508). WBC count consistently showed significant exposure-response and dose–response relationships in both sexes. Conclusions WBC count was found to be a consistent effect marker of cigarette smoke exposure, while the association between CRP level and smoking was inconsistent and varied by sex. The sex-specific response to cigarette smoke exposure warrants further exploration in future studies. Implications Cigarette smoke exposure is known to increase inflammation and has been thought to increase CRP, a significant inflammation marker. However, recent studies have reported conflicting results regarding the dose-dependent association between cigarette smoke exposure and CRP. This study found that the association between smoking and CRP is inconsistent and varies by sex, showing significant exposure response in men but not in women. Furthermore, the study suggests that WBC count is a more consistent marker for cigarette smoke exposure. [ABSTRACT FROM AUTHOR]

Introduction: Commercial tobacco use was systematically embedded as a valuable commodity through colonisation that continues to be exploited for profit by the Tobacco Industry. There have been significant declines in current smoking prevalence among Aboriginal and Torres Strait Islander peoples 18 years and over, from 55% in 1994 to 43% in 2018–2019. This paper seeks to better understand smoke‐free behaviours, and to systematically quantify associations between a range of SDOH and non‐smoking/never‐smoking among Aboriginal and Torres Strait Islander adults (≥18) living in regional Australia. Objective: To explore the social determinants of health (SDOH) related to non‐ and never‐smoking among Aboriginal and Torres Strait Islander peoples in regional Australia. Design: Cross‐sectional analysis of the NATSIHS, weighted to the Aboriginal and Torres Strait Islander adult population living in regional Australia, was conducted. Participants were characterised as people who were current smokers, never‐smokers and non‐smokers (ex‐ and never‐smokers). The social determinants of health exposures related to socioeconomic position, well‐being and access to healthcare. Setting: Regional Australia is distinct from urban and remote areas, based on the ASGS Remoteness Structure (ABS) 2018–2019. Participants: Aboriginal and Torres Strait Islander adults (≥18 years) who were selected, consented and asked questions about smoking in the National Aboriginal and Torres Strait Islander Health Survey (NATSIHS 2018/19). Results: High income was associated with non‐smoking (Prevalence Ratio [PR] = 2.07; 95% CI: 1.66–2.57) and never‐smoking (PR = 2.02; 1.46–2.79), as was completing year 10 (non‐smoking PR = 1.34; 1.12–1.61 and never‐smoking PR = 1.56; 1.20–2.03). Better food security was associated with a higher prevalence of never‐smoking (PR = 2.42; 1.48–3.98). Lower psychological distress scores were associated with non‐smoking (PR = 1.30; 1.10–1.53) and never‐smoking (PR = 1.56; 1.21–2.01). Never‐smoking was more frequent in participants reporting no experiences of unfair treatment (PR = 1.59; 1.22–2.06). Having a usual healthcare provider was associated with non‐smoking (PR = 1.38; 1.02–1.86). Positive exposure to the SDOH were associated with non‐ and never‐smoking among Aboriginal and Torres Strait Islander adults in regional Australia. Structural and systemic changes to address the SDOH, including discrimination and racism, are expected to accelerate non‐smoking behaviours and improve health outcomes for Aboriginal and Torres Strait Islander peoples.

Leukocyte and Platelet-Rich Fibrin (L-PRF) is part of the second generation of platelet-concentrates. L-PRF derived from nonsmokers has been used in surgical procedures, with its beneficial effects in wound healing being proven to stimulate biological activities such as cell proliferation, angiogenesis, and differentiation. Cigarette smoking exerts detrimental effects on tissue healing and is associated with post-surgical complications; however, evidence about the biological effects of L-PRF derived from smokers is limited. This study evaluated the impact of L-PRF secretome (LPRFS) derived from smokers and nonsmokers on angiogenesis and osteoblast differentiation. LPRFS was obtained by submerging L-PRF membranes derived from smokers or nonsmokers in culture media and was used to treat endothelial cells (HUVEC) or SaOs-2 cells. Angiogenesis was evaluated by tubule formation assay, while osteoblast differentiation was observed by alkaline phosphatase and osterix protein levels, as well as in vitro mineralization. LPRFS treatments increased angiogenesis, alkaline phosphatase, and osterix levels. Treatment with 50% of LPRFS derived from smokers and nonsmokers in the presence of osteogenic factors stimulates in vitro mineralization significantly. Nevertheless, differences between LPRFS derived from smokers and nonsmokers were not found. Both LPRFS stimulated angiogenesis and osteoblast differentiation in vitro; however, clinical studies are required to determine the beneficial effect of LPRFS in smokers. [ABSTRACT FROM AUTHOR]

IntroductionCigarette gifting is commonly practiced in China and has contributed to the social acceptability and high prevalence of cigarette smoking in the country. As a result, nonsmokers in China are particularly susceptible to smoking. While previous studies have examined cigarette gifting behaviors among smokers, little is known about cigarette gifting among nonsmokers.Aims and methodsThis study aimed to examine the percentage and correlates of giving and receiving cigarettes as gifts among adult nonsmokers in China. We analyzed nonsmokers (N = 1813) aged ≥18 years using data from the International Tobacco Control China Wave 5 Survey. Descriptive statistics summarized the characteristics of those who gave and received cigarettes as gifts. Multivariable logistic regression models were used to identify factors associated with the two behaviors.ResultsAmong nonsmokers, 9.9% reported giving cigarettes as gifts to family or friends in the last 6 months. A higher level of knowledge about smoking harms was associated with lower adjusted odds of gifting cigarettes. Nonsmokers aged 25-39 years, with middle income, positive attitude toward cigarette gifts, exposure to anti-smoking information, and exposure to smoking promotion, and those who reported receiving cigarettes as gifts from family or friends were more likely to give cigarettes as gifts. A total of 6.6% of nonsmokers reported receiving cigarettes as gifts in the last 6 months. High education, neutral or positive attitude toward cigarette gifts, exposure to anti-smoking information, exposure to smoking promotion, and having smoking friends were associated with receiving cigarettes as gifts.ConclusionsIt is concerning that Chinese cultural norms that support cigarette gifting have extended to giving nonsmokers cigarettes as gifts. Effective anti-smoking messages are needed. Changing the norms around cigarette gifting and increasing knowledge about smoking harms should help reduce cigarette gifting among nonsmokers.ImplicationsEasy access to cigarettes received as gifts, along with the wide acceptance of smoking in China, places Chinese nonsmokers in a risky position. More educational campaigns targeting nonsmokers to proactively prevent them from smoking are called for. The ineffectiveness of existing anti-smoking information highlights the need for more effective anti-smoking messages. That attitude toward cigarette gifts is the strongest predictor of giving cigarettes as gifts suggests the need for interventions to reverse the positive attitude about cigarette gifting to decrease the popularity of this activity.

Amygdala activity in context of the splenocardiac model has not been investigated in healthy, young adults and has not been compared between nonsmokers, electronic cigarette users, and smokers. The purpose of the current study was to determine whether fluorodeoxyglucose positron emission tomography/computer tomography (FDG PET/CT) scans would demonstrate positively correlated metabolic activity in the amygdala, bone marrow, spleen, and aorta, elucidating activation of the splenocardiac axis in otherwise healthy young people who use tobacco products compared to nonusers. Moreover, the study was conducted to evaluate whether electronic cigarette users and tobacco smokers have similar levels of inflammation compared to nonusers. In 45 healthy adults (mean age = 25 years), including nonsmoker (n = 15), electronic cigarette user (n = 16), and smoker (n = 14) groups, metabolic activity in the amygdala, spleen, aorta, bone marrow of thoracic vertebrae, and adjacent erector spinae skeletal muscle was quantified through visualization of radioactive glucose (18 FDG) uptake by FDG-PET/CT. The maximum standardized uptake value for each region was calculated for correlation analyses and comparisons between groups. In correlation analyses, metabolic activity of the amygdala correlated with metabolic activity in the aorta (r = 0.757), bone marrow (r = 0.750), and spleen (r = 0.665), respectively. Metabolic activity in the aorta correlated with 18 FDG uptake in the thoracic vertebrae (r = 0.703) and spleen (r = 0.594), respectively. Metabolic activity in the spleen also correlated with 18 FDG uptake in the bone marrow (r = 0.620). Metabolic activity in the adjacent erector spinae skeletal muscle (our control tissue) was not positively correlated with any other region of interest. Finally, there were no statistically significant mean differences in metabolic activity between the three groups: nonsmokers, electronic cigarette users, and smokers in any target tissue. Amygdala metabolic activity, as measured by 18 FDG uptake in FDG-PET/CT scans, positively correlated with inflammation in the splenocardiac tissues, including: the aorta, bone marrow, and spleen, underscoring the existence of a neural-hematopoietic-inflammatory axis in healthy, young adults.

OBJECTIVE: Tobacco use is an important risk factor for more than 20 types of cancer, especially cardiovascular and respiratory diseases, and many other health problems. Cigarettes are one of the most commonly used tobacco products in the world, and they can cause both physical and mental addiction. Adolescence is known to be the highest-risk period in terms of addiction among all age groups. As a result, smoke-free campus practices have become even more important in universities. This study investigates the prevalence of smoking among Pamukkale Medical School students and their views and behaviors regarding smoke-free campus practices. MATERIAL AND METHODS: This cross-sectional study was conducted with 548 medical students at Pamukkale Universıty Faculty of Medicine during the academic year 2021-2022, between April 1-29, 2022. A face-to-face interview was conducted. Students' smoking status and their views about a smoke-free campus were assessed. In the questionnaire, the independent variables were socio-demographic characteristics, duration of staying in a smoke-free environment, smoking status in the place of residence, areas where smoking is most common, Fagerström nicotine dependence level, knowledge about smoke-free campus applications and campuses with the smokefree application. The Statistical Package for the Social Sciences version 21.0 package program was used to analyze the data. Descriptive statistics are presented with numbers and percentages for categorical variables, while the arithmetic mean and standard deviation are used for continuous variables. The chi-square test was used to compare categorical variables, and the Kolmogorov-Smirnov analysis was used to test the compatibility of data to normal distribution. RESULTS: The student smoking rate increased significantly as the number of semesters increased (P = .021). The smoking rate of male students was higher than that of female students (P = .001). The smoking rate of students living with their family or relatives was lower (P = .020). Smokers (14.7%) were more likely to have heard about the introduction of smoke-free zones on campus than nonsmokers (11%) (P = .280). 81.4% of students affirmed the statement, "The number of smoke-free rooms should be increased," and 84.3% responded, "I support the existence of smoke-free spaces." Nonsmoking students (90.8%) are more likely to agree that smoke-free spaces should be increased than those who smoke (57.7%) (P < .001). Among the students, 17.6% of nonsmokers and 37.8% of smokers find the information about smoke-free spaces sufficient (P < .001). The rate of those who consider smoke-free space inspections to be sufficient is lower for nonsmoking students than for nonsmokers (P = .017). Nonsmokers (89.5%) support the existence of smoke-free spaces to a higher degree than smokers (71.2%) (P < .001). CONCLUSION: One-third of Pamukkale University Faculty of Medicine students smoke, and smoking rates are higher among men and those who do not live with family or relatives. All participants strongly support the existence of smoke-free zones (84.3%), while a proportion of tobacco users (31.4%) support the implementation of a smoke-free campus. Student opinions of the smoke-free zones and the smoke-free campus application are more positive among nonsmokers than smokers. [ABSTRACT FROM AUTHOR]

Aims/Objectives: The aim of this cross-sectional observational study was to investigate cytogenetic damage to the buccal mucosa in non-smokers and consumers of traditional combustible tobacco products and non-combustible alternatives. Methods: A total of 160 participants were divided into four groups according to the type of product used, including non-smokers, users of conventional combustible tobacco (cigarettes), heated tobacco, and electronic, tobacco-free vapor products (e-cigarettes). Buccal mucosa samples were analyzed using the micronucleus cytome assay to assess cytotoxic and genotoxic damage. Results: E-cigarette users showed significantly higher values for all tested parameters in the micronucleus test compared to non-smokers (p < 0.05). Similarly, users of tobacco heating products showed an increase in all parameters (p < 0.05), with the exception of the number of cells with micronuclei. Conventional cigarette smokers showed a notable increase in the number of binucleated cells and cells with karyorrhexis and karyolysis (p ≤ 0.05). When assessing the differences between users of traditional combustible tobacco products and non-combustible alternatives, these did not appear to be significant, except for e-cigarette users, who had significantly more cells with condensed chromatin (p ≤ 0.001), while users of tobacco heating products had more pyknotic cells (p ≤ 0.001). Conclusion: The results of this study underscore the heightened occurrence of cytotoxic and genotoxic damage in users of both conventional combustible tobacco products and non-combustible alternatives compared to non-smokers, emphasizing the detrimental impact of these products on the oral mucosa.

Heart rate variability (HRV) is a simple way to explore autonomic nervous activity. Current studies emphasize the need to identify a dependent relationship between smoking habit and HRV. The findings of these studies could demonstrate that smoking can have both an acute and a chronic effect on HRV. The aim of this study is to investigate the relationship between smoking and anthropometric data such as body weight, body fat distribution and heart rate variability. Our study involves measuring HRV parameters at rest and during two tests that are part of the Ewing test battery. Through the obtained data we can demonstrate that active smoking is associated with a reduction in HRV. At the same time, we can state that HRV is affected by different behavior patterns of the smoker.complex individualized rehabilitation treatment. [ABSTRACT FROM AUTHOR]

INTRODUCTION Smoking is one of the most important preventable causes of cardiovascular diseases. Vascular disease caused by smoking is associated with vascular endothelial damage, platelet aggregation, and adhesion. In our study, we examined the effect of chronic smoking on vessel wall stiffness in smokers and control group by measuring carotid artery wall stiffness by shear wave ultrasonography. METHODS Sixty-two smokers of similar ages and genders, and 67 people who never smoked in the last ten years were included as the control group in this crosssectional study. Arterial wall stiffness over the common carotid arteries of all participants was measured by shear wave elastography (SWE). In addition, each patient's blood pressure, fasting blood glucose, body mass index (BMI), HDL and LDL cholesterol measurements were recorded. RESULTS Arterial wall stiffness values in smokers were found to be statistically significantly higher than in non-smokers. The mean of SWE measurements of the smokers was 47.3 ± 6.2 kPa, and that of the control group was 42.9 ± 4 kPa. The mean values of HDL and LDL of the smokers were 46.9 ± 5.6 mg/dL and 147.3 ± 9.3 mg/dL, respectively, and those of the control group were 50.3 ± 5.1 mg/dL and 136.9 ± 5.9 mg/dL. The LDL cholesterol values were statistically significantly higher in smokers compared to the control group, and HDL cholesterol values were statistically significantly lower in smokers. CONCLUSIONS In our study, the arterial wall stiffness values measured by the SWE technique were higher in smokers than non-smokers. [ABSTRACT FROM AUTHOR]

Reactive oxygen species (ROS) are molecules that are produced by a variety of metabolic processes that can lead to oxidative stress and subsequent direct or indirect tissue damage, are linked to the pathogenesis of the majority of inflammatory processes and result in periodontal disorders. Lipid peroxidation product malondialdehyde (MDA) caused by ROS can lead to tissue injury. The aim of this study was to assess and compare the concentrations of malondialdehyde (MDA) in periodontal health and periodontal disease in nonsmokers and smokers, and to establish its usefulness as diagnostic indicators for periodontal disease.125 male patients were categorized as control: 25 healthy nonsmokers,25 nonsmokers with gingivitis,25 smokers with gingivitis, 25 nonsmokers with periodontitis and 25 smokers with periodontitis. For at least 10 minutes, 2ml of unstimulated saliva was collected. Periodontal clinical parameters (PI, BOP, PPD and CAL) were recorded to assess each subject's periodontal health. An enzyme-linked immunosorbent assay measured salivary MDA levels. All groups had higher levels of salivary MDA (P < 0.05) when compared to the healthy controls, except for the nonsmoker periodontitis group was not statistically different from the control group; however, smoker groups had higher MDA levels than nonsmoker groups. With the limitations of this case-control study, it may be suggested that the oxidative stress biomarker MDA was higher in periodontal diseases associated with risk factors such as smoking and this biomarker has the potential to be employed as a diagnostic biomarker for periodontal diseases.

Introduction: Tobacco smoking is a common addiction in our society. The toxic chemical compounds present in tobacco smoke cause epithelial damage and inflammation of the airways. Chronic smoking results in the thickening of the pulmonary arterial wall and vasoconstriction, leading to the development of pulmonary arterial hypertension. Hence, measurement of pulmonary artery diameter using Contrast Enhanced Computed Tomography (CECT) may be helpful in the early detection of pulmonary arterial hypertension. Aim: To compare the diameters of the Main Pulmonary Artery (MPA), Right Pulmonary Artery (RPA), and Left Pulmonary Artery (LPA) using CECT thorax in smokers and non-smokers. Materials and Methods: A cross-sectional study was conducted from April 2021 to March 2022 in the department of radiodiagnosis, KS Hegde Hospital, Karnataka, India, consisting of 100 patients referred for CECT thorax in the age group of 18-85 years. They were divided into two groups: smokers and non-smokers, with 50 patients in each group. They were further categorised into three age groups: < 50 years, 50-60 years, and >60 years. The widest diameters of the MPA were measured at the level of bifurcation of the artery and perpendicular to the long axis of the artery. At this level, RPA and LPA diameters were measured at the widest portion on 1.25 mm axial images of the arterial phase. Variation in the pulmonary artery diameter was compared between smokers and non-smokers with respect to age and analysed by unpaired t-test and Pearson correlation. Results: Diameters of MPA, RPA, and LPA were statistically significant (p<0.05) in smokers compared to non-smokers. In smokers, MPA and RPA diameters correlated with age, which was statistically significant (p<0.05). No significant correlation (p>0.05) was shown between age and MPA, RPA, and LPA diameter in non-smokers. The mean MPA diameter showed a significant difference (p<0.05) in all three age groups. Conclusion: The diameter of the pulmonary artery is statistically significant in smokers compared to non-smokers. Hence, assessment of pulmonary artery diameters among smokers using CECT thorax will help to diagnose Pulmonary Hypertension (PH) at an early stage. [ABSTRACT FROM AUTHOR]

COTININE , *NICOTINE , *ADULTS - Abstract
Introduction Secondhand smoke (SHS) poses a significant health risk. However, individuals who do not smoke may be unaware of their exposure, thereby failing to take protective actions promptly. Aims and Methods We assessed the prevalence of underreported nicotine exposure in a nationally representative sample of US nonsmoking adults using data from the US National Health and Examination Survey. Individuals with underreported nicotine exposure were defined as those who reported no exposure to all tobacco products (traditional tobacco, nicotine replacements, and e-cigarettes) or SHS, yet had detectable levels of serum cotinine (>0.015 ng/mL). We fitted logistic regression models to determine sociodemographic and chronic condition factors associated with underreported nicotine exposure. Results Our analysis included 13 503 adults aged 18 years and older. Between 2013 and 2020, the prevalence of self-reported SHS exposure, serum cotinine-assessed nicotine exposure, and underreported nicotine exposure among US nonsmokers were 22.0%, 51.2%, and 34.6%, respectively. Remarkably, 67.6% with detectable serum cotinine reported no SHS exposure. Males, non-Hispanic blacks, individuals of other races (including Asian Americans, Native Americans, and Pacific Islanders), and those without cardiovascular diseases were more likely to underreport nicotine exposure than their counterparts. The median serum cotinine value was higher in respondents who reported SHS exposure (0.107 ng/mL) than in those who reported no exposure (0.035 ng/mL). We estimate that approximately 56 million US residents had underreported nicotine exposure. Conclusions Over a third of US nonsmokers underreport their nicotine exposure, underlining the urgent need for comprehensive public awareness campaigns and interventions. Further research into sociodemographic determinants influencing this underreporting is needed. Implications Understanding the extent of underreported nicotine exposure is crucial for developing effective public health strategies and interventions. It is imperative to bolster public consciousness about the risks associated with SHS. Additionally, surveillance tools should also incorporate measures of exposure to outdoor SHS and e-cigarette vapor to enhance the quality of data monitoring. Findings from this study can guide tobacco control initiatives and inform smoke-free air legislation. [ABSTRACT FROM AUTHOR]

SMOKING statistics ,NON-smokers ,AIR flow ,TOBACCO - Abstract
This article, published in the National Journal of Physiology, Pharmacy & Pharmacology, discusses the impact of tobacco smoking on pulmonary function. The study found that smokers had lower spirometric variables, such as forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow rate (PEFR), compared to non-smokers. The reduction in lung function was also proportional to the number of years the person had been smoking. The article emphasizes the importance of early detection and support for asymptomatic smokers, as early cessation is linked to improved survival. [Extracted from the article]
