Objective: To describe a murine model of emphysema induced by a combination of exposure to cigarette smoke (CS) and instillation of porcine pancreatic elastase (PPE). Methods: A total of 38 C57BL/6 mice were randomly divided into four groups: control (one intranasal instillation of 0.9% saline solution); PPE (two intranasal instillations of PPE); CS (CS exposure for 60 days); and CS + PPE (two intranasal instillations of PPE + CS exposure for 60 days). At the end of the experimental protocol, all animals were anesthetized and tracheostomized for calculation of respiratory mechanics parameters...

Little is known about environmental risk factors for hypodontia. The objective of this study was to investigate the association between hypodontia and common environmental risk factors, such as maternal smoking and alcohol and caffeine consumption during pregnancy. Eighty-three hypodontia cases with 1 or more missing permanent lateral incisors and/or 1 or more missing premolars were enrolled in this clinic-based case-control study. Some 253 controls with no missing teeth were frequency matched to cases by age and sex...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by airflow obstruction due to an abnormal inflammatory response of the lungs to noxious particles or gases, for example, cigarette smoke. The pattern of care for people with moderate to very severe COPD often involves regular lengthy hospital admissions, which result in high healthcare costs and an undesirable effect on quality of life. Research over the past decade has focused on innovative methods for developing enabling and assistive technologies that facilitate patient self-management...

Nicotine is the principal addictive agent present in Naswar, a smokeless dipping tobacco product. 5-Hydroxytryptamine (5-HT) has been implicated in the reinforcement properties of nicotine. Also, the hypothalamic-pituitary-adrenal (HPA) axis is of vital importance in evaluating the response to stress and nicotine addiction. The study aimed to evaluate serum tryptophan and cortisol levels in Naswar users in relation to addiction. Additionally, serum cotinine levels were also determined to assess daily nicotine exposure...

AIM: To demonstrate a direct inhibitory effect of cigarette smoke exposure on paraoxonase 1 activity in a murine in vivo model. METHODS: At 8 weeks old, we randomized 10 C57/bl6 mice to an environment consisting of either filtered air or cigarette smoke for 6 months. Smoke exposure (7 hours per day, 5 days per week) was standardized using a model TE-10 smoking machine and adjusted to maintain constant sidestream and mainstream smoke. After 6 months of exposure, we assessed differences in lung air space, cholesterol, lipid, and lipoprotein profiles, as well as paraoxonase activity in mice exposed to cigarette smoke extract compared to unexposed control mice...

Introduction: Financial incentives for smoking cessation increase smoking abstinence and decrease Beck Depression Inventory (BDI) scores among depression-prone pregnant and postpartum women. The present study is a secondary analysis using the Brief Symptom Inventory (BSI) to examine whether this treatment impacts a broader array of mood and anxiety symptoms. Methods: Participants (N = 253) were pregnant cigarette smokers who participated in four controlled clinical trials examining the efficacy of financial incentives for smoking cessation...

We have previously found that cigarette smoke disrupts metabolic function, in part, by increasing muscle ceramide accrual. To further our understanding of this, we sought to determine the role of the cytokine high-mobility group box 1 (HMGB1), which is increased with smoke exposure, in smoke-induced muscle metabolic perturbations. To test this theory, we determined HMGB1 from lungs of human smokers, as well as from lung cells from mice exposed to cigarette smoke. We also treated cells and mice directly with HMGB1, in the presence or absence of myriocin, an inhibitor of serine palmitoyltransferase, the rate-limiting enzyme in ceramide biosynthesis...

BACKGROUND: Abusive inhalation of butane gas is becoming a serious public health problem among teenagers and young adult population; however, there has been little reporting on explosion burns associated with abuse of butane cigarette lighter fluid. METHODS: Retrospective study was conducted of 22 patients who were burned in last 2 years in explosion of butane gas, a flammable, odorless, and colorless aliphatic hydrocarbon. RESULTS: Details of sociodemographic profile of the patients, any underlying psychiatric illness, alcohol abuse, depth of burn injury, any associated injury, duration of hospitalization, and percentage of burned area were recorded and analyzed...

BACKGROUND: Both adverse early life exposures and adult smoking can negatively influence adult lung function trajectory but few studies consider how the impact of early life exposures may be modified by subsequent smoking. METHODS: The Medical Research Council National Survey of Health and Development is a nationally representative cohort, initially of 5362 individuals, followed since enrolment at birth in March 1946. Using data collected prospectively across life and multilevel modelling we investigated how the relationships between early life exposures (infant lower respiratory infection, manual social class, home overcrowding and pollution exposure) and FEV1 and FVC trajectories between ages 43 and 60-64 were influenced by smoking behaviour...

Chronic inflammation serves an important role in lung carcinogenesis, thus genetic polymorphisms involved in this pathway may affect the risk of lung cancer. The present case-control study focused on the association between lung cancer risk and genetic polymorphisms involved in inflammatory pathways. The study comprised 462 lung cancer cases and 379 controls from Japan. The roles of interleukin 8 (IL8) rs4073, nuclear factor kappa B (NFκB) rs28362491, cytochrome b-245, alpha polypeptide (CYBA) rs4673, NAD(P) H dehydrogenase, quinone 1 (NQO1) rs1800566, nitric oxide synthase 2 and inducible (NOS2) rs2297518 polymorphisms in lung carcinogenesis were investigated...

Oxidative stress/damage resulting from exposure to cigarette smoke plays a critical role in the development of tobacco-caused diseases. Carbonyls and free radicals are two major classes of oxidants in tobacco smoke. There is little information on the combined delivery of these oxidants across different cigarette brands; thus, we set out to measure and compare their levels in mainstream smoke from popular US cigarettes. Mainstream smoke from 28 different cigarette brands produced by smoking (FTC protocol) was analyzed for five important, abundant carbonyls, and levels were compared to previously determined free radical for the same brands...

Cancer survivors who continue to smoke have poorer response to treatment, higher risk for future cancers and lower survival rates than those who quit tobacco after diagnosis. Despite the increased risk for negative health outcomes, tobacco use among Alaskan cancer survivors is 19%, among the highest in the nation. To characterize and address tobacco cessation needs among cancer survivors who called a quit line for help in quitting tobacco, Alaska's Comprehensive Cancer Control program initiated a novel partnership with the state's Tobacco Quit Line...

Resting state functional brain connectivity (rsFC) may be an important neuromarker of smoking behavior. Prior research has shown, among cigarette smokers, that nicotine administration alters rsFC within frontal and parietal cortices involved in executive control, as well as striatal regions that drive reward processing. These changes in rsFC have been associated with reductions in withdrawal symptom severity. We currently have a limited understanding of how rsFC is affected by the use of electronic cigarettes (ecigs), an increasingly popular class of products, the members of which deliver nicotine with varying effectiveness...

RATIONALE: Effective translation of genomics research into practice depends on public acceptance of genomics-related health information. OBJECTIVE: To explore how smokers come to accept or reject information about the relationship between genetics and nicotine addiction. METHODS: Thirteen focus groups (N = 84) were stratified by education (seven < Bachelor's degree, six ≥ Bachelor's degree) and race (eight black, five white). Participants viewed a 1-min video describing the discovery of a genetic variant associated with increased risk of nicotine addiction and lung cancer...

This study assessed racial/ethnic moderation of the association between school prevalence of lifetime e-cigarette use and students' use. Using multilevel regression methods and data from the 2014 US National Youth Tobacco Survey, we found attending schools with high rates of e-cigarette use was positively associated with students' lifetime use of e-cigarettes, especially for white students. A cross-level interaction term indicated a weaker association between non-Hispanic black race and attending high-use schools (odds ratio [OR] =0...
