Abstract
INTRODUCTION: Alternative tobacco products, such as snus, are emerging in the U.S. market. Understanding correlates of awareness and use, particularly judgments about harm and addictiveness, can inform public health communications about these products. METHODS: Data were collected from a web panel representative of the U.S. population in March 2013 (N = 2,067). The survey assessed awareness and use of snus among adults. Absolute and comparative snus judgments, intentions, smoking status, and sociodemographic variables were measured. Bivariate and multivariable logistic regression analyses were conducted to examine associations between these variables and snus awareness and use. RESULTS: Nearly 36% of the population was aware of snus, and 5.2% reported ever using snus. Current cigarette smokers were about 4 times more likely as nonsmokers to report snus awareness and use. Sociodemographic correlates of snus awareness and use included being male, employed full time, and younger. Compared with respondents who perceived snus to be as harmful and as addictive as cigarettes, those who perceived snus to be less harmful and less addictive than cigarettes were more likely to have used snus. CONCLUSIONS: Current smokers are more likely to be aware of and have used snus. Multiple tobacco product use poses a significant challenge for public health efforts to reduce tobacco-associated morbidity and mortality. Perceptions that snus is less harmful and less addictive compared with cigarettes are associated with snus use. These judgments can inform public health communications about emerging tobacco products and multiple product use.

Abstract
The purpose of this review is to examine the rapidly expanding literature regarding the effects of prenatal tobacco and postnatal secondhand smoke (SHS) exposure on child health and development. Mechanisms of SHS exposure are reviewed, including critical periods during which exposure to tobacco products appears to be particularly harmful to the developing fetus and child. The biological, biochemical, and neurologic effects of the small fraction of identified components of SHS are described. Research describing these adverse effects of both in utero and childhood exposure is reviewed, including findings from both animal models and humans. The following adverse physical outcomes are discussed: sudden infant death syndrome, low birth weight, decreased head circumference, respiratory infections, otitis media, asthma, childhood cancer, hearing loss, dental caries, and the metabolic syndrome. In addition, the association between the following adverse cognitive and behavioral outcomes and such exposures is described: conduct disorder, attention-deficit/hyperactivity disorder, poor academic achievement, and cognitive impairment. The evidence supporting the adverse effects of SHS exposure is extensive yet rapidly expanding due to improving technology and increased awareness of this profound public health problem. The growing use of alternative tobacco products, such as hookahs (a.k.a. waterpipes), and the scant literature on possible effects from prenatal and secondhand smoke exposure from these products are also discussed. A review of the current knowledge of this important subject has implications for future research as well as public policy and clinical practice.

Abstract
This paper presents, on the one hand, the study of the influence of the pH of the medium on the determination of bisphenol F (BPF), bisphenol A (BPA) and their corresponding diglycidyl ethers (BFDGE and BADGE, respectively) by GC-MS after a solid-phase extraction step, using BPA-d16 as internal standard and Parallel Factor Analysis (PARAFAC) decomposition as a multi-way tool for the unequivocal identification and quantification of the four analytes. As the structure of both BFDGE and BADGE has two 2,3-epoxypropoxy groups that can undergo an acid- or base-catalyzed ring-opening via nucleophilic substitution reactions, several samples spiked with the four analytes were set to different pH values between 2 and 12. The best results were obtained in the pH region 8-10, being 9 the most suitable value. Coelution of interferents was overcome using the PARAFAC decomposition; otherwise, the presence of some analytes could not have been ensured according to the regulations currently in force. Secondly, the release of BPA from polycarbonate glasses into food simulant D1 (ethanol 50% (v/v)) over time was studied through seven migration tests and the differences found in this migration process with the incubation temperature (50 and 70 degrees C) were evaluated. A nonlinear regression was used to fit the experimental data following an exponential relation between the concentration of BPA transferred from every glass and the respective migration test. None of the quantities of BPA released exceeded the specific migration limit of 0.6mgkg(-1) laid down for this compound in the Commission Regulation (EU) No 10/2011, so the compliance of the glasses evaluated was ensured. The average recovery percentages of the four analytes at a fortification level of 800ngL(-1) ranged from 50.14 to 92.75%. The detection capability (CCbeta) of the method for BPA was 2.60mugL(-1) for n=2 replicates, with probabilities of false positive and false negative fixed at 0.05.

Abstract
Dong Y, Qi B, Feng XY, Jiang CM. Meta-analysis of Barrett's esophagus in China. World J Gastroenterol 2013;19(46):8770-8779 The disease pattern of Barrett's esophagus (BE) in China is poorly characterised particularly in comparison with other developed countries. This meta-analysis of 3873 cases of BE collated from 69 clinical studies conducted in 25 provinces between 2000 and 2011 investigated the epidemiology and characteristics of BE in China compared to Western countries. The total endoscopic detection rate of BE was 1.0% (95%CI: 0.1%-1.8%) with an average patient age of 49.07 +/- 5.09 years, lower than many Western countries.The authors postulate this may be attributed to environmental risk factor variation, distinct genetics and different medical practice including diagnostic criteria for BE and expertise in endoscopy. This study identified a 1.781 male predominancefor BE in China, consistent with Western reports. Short-segment BE accounted for 80.3% of cases with island type and cardiac type the most common endoscopic (44.8%) and histological (40.0%) manifestations respectively. Of the 1283 BE cases followed up for three to 36 months the incidence of esophageal cancer was 1.418 per 1000 person-years, lower than the incidence reported in Western countries. Lee HS, Jeon SW. Barrett esophagus in Asia: same disease with different pattern. ClinEndosc 2014;47(1):15-22 Barrett's esophagus (BE) is a common, pre-cancerous condition characterised by intestinal metaplasia of squamous esophageal epithelium usually attributed to chronic gastric acid exposure. This review article explores important differences in the disease pattern of BE between Asian and the Western countries. Overall the prevalence of BE is lower in Asia compared to the West with a greater proportion of short-segment type. The authors identify great variability in the endoscopic and pathologic diagnostic criteria for BE. Many of the studies in Asian countries did not use a standardised four-quadrant biopsy protocol which may have led to an underestimation of BE prevalence. The review highlights an increasing incidence of esophageal adenocarcinoma in the West but unclear disease trend in Asia with inter-country variability. Similarly in Asian and Western countries BE is associated with the presence of hiatus hernia, advancing age, male gender, alcohol consumption, smoking, abdominal obesity and longer duration of gastro-esophageal reflux disease. The authors postulate that Helicobacter pylori infection, more prevalent in Asia than the West, may have a protective effect on BE. There is a need for larger, prospective studies to further clarify the disease pattern of BE in Asian countries. Clearly standardisation of the diagnostic process for BE is important to validate the differences in disease trends between Asian and Western countries. Kiadaliri AA. Gender and social disparities in esophagus cancer incidence in Iran, 2003-2009: a time trend province-level study.Asian Pac J Cancer Prev 2014;15(2):623-7 Esophageal cancer (EC) is a major cause of morbidity and mortality particuarly in Iran where the incidence rate exceeds the global average. An understanding of the factors influencing the province-specific incidence of EC in Iran is important to inform disease-prevention strategies and address health inequalities. This ecological study used cancer registry data to investigate the relationship between gender and social class and the incidence of EC in Iran at province-level between 2003 and 2009. The age standardised incidence rates (ASIR) of EC were greatest in the Northern provinces of Iran, specifically Razavi Khorasan in males and Kordestan in females. Overall the EC incidence did not significantly differ according to gender. Interestingly, during the study period the ASIR increased by 4.6% per year in females (p=0.08) and 6.5% per year in males (p=0.02). This may reflect increasing rates of establised risk factors for EC including obsesity and gastro-esophageal r

Abstract
INTRODUCTION: The prevalence of smoking across racial/ethnic groups has declined over the years, yet racial health disparities for smoking persist. Studies indicate that non-Hispanic Black smokers attempt to quit smoking more often compared to non-Hispanic White smokers but are less successful at doing so. Research suggests that motives to quit smoking differ by race, however, less is known about the role of motives to smoke in explaining racial differences in attempts to quit smoking. METHODS: This study examined whether smoking motives accounted for the differential rates in quit attempts between non-Hispanic Black (n=155) and non-Hispanic White (n=159) smokers. Data were culled from a larger study of heavy-drinking smokers. The Wisconsin Index of Smoking Dependence Motives (WISDM) assessed motives to smoke. RESULTS: As expected, Black and White smokers reported similar smoking patterns, yet Black smokers reported higher rates of failed attempts to quit smoking than White smokers. Findings indicated that Black, compared to White, smokers endorsed lower scores in the negative reinforcement, positive reinforcement, and taste WISDM subscales and scores in these subscales mediated the relationship between race and quit attempts. CONCLUSIONS: In this study, Blacks, compared to Whites, endorsed lower motives to smoke, which are generally associated with successful quit attempts, yet they experienced more failed attempts to quit smoking. This study demonstrates racial health disparities at the level of smoking motives and suggests that Black smokers remain vulnerable to failed quit attempts despite reporting lower motives to smoke.

Abstract
INTRODUCTION: U.S. adolescents increasingly use e-cigarettes. The perceived harm of e-cigarettes has not been described, nor has the correlation between harm perception and e-cigarette use been assessed. This study examines correlates of e-cigarette harm perception and use of e-cigarettes in a national survey. METHODS: We used cross-sectional nationally representative data from the 2012 National Youth Tobacco Survey (n = 24,658). Cross-tabulations and multivariate ordered probit and logistic regression models were employed to assess relative harm perception and e-cigarette use. RESULTS: Half of U.S. adolescents had heard of e-cigarettes. Of these, 13.2% (95% confidence interval [CI] = 11.7-14.9) and 4.0% (95% CI = 3.4-4.7) reported ever or currently using e-cigarettes, respectively. Of those aware of e-cigarettes, 34.2% (95% CI = 32.8-35.6) believed e-cigarettes were less harmful than cigarettes. Among those trying e-cigarettes, 71.8% (95% CI = 69.0-74.5) believed e-cigarettes were comparatively less harmful. Females and those >/= 17 years old were more likely to perceive e-cigarettes as more harmful relative to cigarettes, while on average Whites, users of other tobacco products, and those with family members who used tobacco were more likely to perceive e-cigarettes as comparatively safer. Among cigarette-naive e-cigarette users, use of other tobacco products and perceived harm reduction by e-cigarettes were, respectively, on average associated with 1.6 and 4.1 percentage-point increases in e-cigarette use. CONCLUSIONS: Perception of e-cigarettes as less harmful than conventional cigarettes was associated with increased e-cigarette use, including among cigarette-naive e-cigarette users. These findings should prompt further scientific investigation and merit attention from regulators.

Abstract
BACKGROUND: The prevalence of water pipe (WP) smoking was studied using a standard questionnaire. Pulmonary function tests were also compared between WP smokers and non-smokers. MATERIALS AND METHODS: The prevalence of WP smoking was studied using a standard questionnaire. Pulmonary function tests including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximal mid-expiratory flow (MMEF), peak expiratory flow (PEF), maximal expiratory flow at 75%, 50%, and 25% of the FVC (MEF75,50,25) were compared between WP smokers and non-smokers. RESULTS: A total of 673 individuals including 372 males and 301 females were interviewed. The number of WP smokers was 58 (8.6%) including 24 males (6.5%) and 34 females (11.3%). All pulmonary functional test (PFT) values in WP smokers were lower as compared to the non-smokers (P

Abstract
INTRODUCTION: The aim of the study is in vitro evaluation of the shear bond strength of composite resin bonded to enamel which is pretreated using acid etchant and Er,Cr:Ysgg. MATERIALS AND METHODS: 40 extracted human teeth were divided in two groups of 20 each (Groups A and B). In Group A, prepared surface of enamel was etched using 37% phosphoric acid (Scotchbond, 3M). In Group B, enamel was surface treated by a an Er, Cr: YSGG laser system (Waterlase MD, Biolase Technology Inc., San Clemente, CA, USA) operating at a wavelength of 2,780 nm and having a pulse duration of 140-200 microsecond with a repetition rate of 20 Hz and 40 Hz. Bonding agent ((Scotchbond Multipurpose, 3M) was applied over the test areas on 20 samples of Groups A and B each, and light cured. Composite resin (Ceram X duo Nanoceramic restorative, Densply) was applied onto the test areas as a 3 x 3 mm diameter bid, and light cured. The samples were tested for shear bond strength. RESULTS: Mean shear bond strength for acid-etched enamel (26.41 +/- 0.66MPa, range 25.155 to 27.150 MPa) was significantly higher (P
