Abstract
INTRODUCTION: The World Health Organization Framework Convention on Tobacco Control recommends that provision of cessation support should be included in national tobacco control strategies. This study examines the impact of the United Kingdom's national smoking cessation strategy on quit attempts, use of treatment and short-term abstinence, relative to the United States, Canada, and Australia where less support is provided. METHODS: Data on quitting behavior and use of support were obtained for all smokers enrolled in the International Tobacco Control 4 Country Survey between 2002 and 2005. Generalized estimating equations were used to calculate the relative odds (adjusted by age, sex, and Heaviness of Smoking Index) that smokers in each country made quit attempts, used behavioral or pharmacological support, and to compare rates of short-term (28 days) abstinence between countries and users of different forms of support. RESULTS: U.K. smokers were less likely to have attempted to quit smoking than those in Australia (odds ratio [OR] = 1.25, 95% CI: 1.12-1.40), Canada (OR = 1.50, 95% CI: 1.34-1.67), and the United States (OR = 1.25, 95% CI: 1.11-1.40) but were more likely to use pharmacotherapy and/or support from a clinic, helpline, or health professional when attempting to quit than smokers in the other countries. U.K. smokers making quit attempts were significantly more likely to achieve 28-day abstinence than those in Australia (OR = 0.59, 95% CI: 0.49-0.71), Canada (OR = 0.72, 95% CI: 0.61-0.87), and the United States (OR = 0.51, 95% CI: 0.42-0.62). CONCLUSIONS: U.K. smokers report fewer quit attempts but are more likely to use support when quitting and to achieve short-term abstinence.

Abstract
BACKGROUND: Extended-spectrum beta-lactamases (ESBLs), including the AmpC type, are important mechanisms of resistance among Enterobacteriaeceae. CTX-M type extended-spectrum beta- lactamases, of which there are now over 90 variants, are distributed globally, yet appear to vary in regional distribution. AmpC beta-lactamases hydrolyze third generation cephalosporins, but are resistant to inhibition by clavulanate or other beta-lactamase inhibitors in vitro. Fecal carriage and rates of colonization by bacteria harboring these resistance mechanisms have been reported in patients with community-acquired infections and in healthy members of their households. Expression of these ESBLs compromises the efficacy of current antibacterial therapies, potentially increasing the seriousness of hospital- and community-acquired Escherichia coli (E. coli) infections.To investigate the occurrence of ESBL-producing E. coli in human fecal flora isolated from two pediatric populations residing in the Libyan cities Zleiten and Abou El Khoms. Isolates were further studied to characterize genes encoding beta-lactam resistance, and establish genetic relationships. METHODS: Antibiotic resistance profiles of phenotypically characterized E. coli isolates recovered from the stools of 243 Libyan children during two surveillance periods in 2001 and 2007 were determined by the disk diffusion method. ESBL-screening was performed using the cephalosporin/clavulanate double synergy disc method, and the AmpC-phenotype was confirmed by the aminophenyl-boronic acid test. ESBL genes were molecularly characterized. Phylogenetic group and multilocus sequence typing (MLST) were determined for ESBL-producing isolates and PFGE was performed to compare banding profiles of some dominant strains. RESULTS: ESBLs were identified in 13.4% (18/134) of E. coli isolates, and nine isolates (6.7%) demonstrated AmpC activity; all 18 isolates contained a CTX-M gene. Three CTX-M gene families (CTX-M-1, n=9; CTX-M-15, n=8 and CTX-M-3, n=1) were distributed in diverse E. coli backgrounds (phylogenetic group D, 39%; B2, 28%; B1, 22% and A, 11%). MLST analysis revealed 14 sequence type (ST) with six new sequence types. The gene encoding the CMY-2 enzyme was detected in five AmpC-positive E. coli. CONCLUSIONS: These results identified heterogeneous clones of CTX-M-producing E. coli in the fecal isolates, indicating that the intestinal tract acts as a reservoir for ESBL-producing organisms, and a trafficker of antibiotic resistance genes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE: Hymenaea stigonocarpa Mart. ex Hayne (Fabaceae) is a medicinal species commonly found in the Brazilian savannah. The stem bark of this medicinal plant, popularly known as "jatoba-do-cerrado", is widely used in tea form to treat gastric pain, ulcers, diarrhoea and inflammation, whereas its fruits pulp is edible. AIM OF THE STUDY: The aim of this study was to investigate the antidiarrheal and anti-ulcer effects of a methanolic extract derived from the stem bark (MHs) and diet with fruit pulp of H. stigonocarpa. MATERIALS AND METHODS: The antidiarrheal action of MHs was measured against the intestinal motility and diarrhoea induced by castor oil in mice. The preventive action of MHs (50, 100, 150 and 200mg/Kg, by oral route (p.o.)) against peptic ulcers was evaluated in experimental rodent models challenged with absolute ethanol, non-steroidal anti-inflammatory drugs (NSAIDs), ischemia-reperfusion (I/R) (200mg/Kg, p.o.) and cysteamine (200mg/Kg, p.o.). The main anti-ulcer mechanisms of action of MHs were analysed as follows: evaluation of the gastric juice parameters, assessment of mucus adherence to the gastric wall, determination of the role of nitric oxide (NO) and sulfhydryl compounds (SH), glutathione (GSH) levels and myeloperoxidase (MPO) activity. The healing effects from MHs (200mg/Kg) and diet with fruit pulp (10%) against gastric and duodenal ulcers induced by acetic acid were also evaluated by treating rats over 7 or 14 consecutive days of treatment. RESULTS: The phytochemical profile of MHs and fruit pulp indicated the presence of phenolic compounds (mainly flavonoids and condensed tannins). MHs (200mg/Kg, p.o.) displayed an antidiarrheal effect and were able to protect gastric mucosa against absolute ethanol (68% protection) and also against the injurious effect of NSAIDs (86% protection) when compared to the group treated with vehicle. These results were accompanied by the prevention of GSH depletion and an inhibition of MPO activity when compared to animals treated with vehicle (P

Abstract
AIMS: The primary aim of this study was to compare the efficacy of smoking cessation treatment using a combination of nicotine patch and bupropion vs. nicotine patch and placebo bupropion. A secondary aim was to investigate whether the efficacy of bupropion is moderated by belief about whether one is receiving active or placebo medication. METHODS: Participants were recruited from a residential substance abuse treatment program and the community. We randomly assigned 148 smokers with between 2 and 12 months of alcohol abstinence to nicotine patch plus bupropion or nicotine patch plus placebo. All participants also received seven counseling sessions. RESULTS: At follow up, differences between medication conditions were not significant. Seven-day point prevalence quit rates in the patch plus bupropion vs. patch plus placebo conditions at week 24 were 6% and 11%, respectively. Differences between groups on prolonged abstinence and time to first smoking lapse were also not significant. However, among participants who received bupropion, those who accurately "guessed" that they were receiving bupropion were more likely to remain abstinent than those who incorrectly believed they were receiving placebo. CONCLUSIONS: Findings do not support combining nicotine patch and bupropion for smoking cessation in this population. However, findings support previous studies suggesting the importance of assessing the blind in smoking cessation studies and its possible moderating effect on medication efficacy. Future directions for enhancing smoking cessation outcome in these smokers include investigations of intensive behavioral and pharmacological interventions, including studies of potential interactions between individual genetic differences and medication efficacy.

Abstract
OBJECTIVE: To investigate parental smoking patterns and their association with wheezing in children. METHODS: We performed a case-control study that included 105 children between 6 and 23 months of age who were divided into two groups: cases (children with 3 previous episodes of wheezing) and controls (healthy children without wheezing). The children's exposure to cigarette smoking was estimated using a questionnaire completed by the mothers and by the children's urinary cotinine levels. RESULTS: Based on both the questionnaire results and cotinine levels, exposure to cigarette smoking was higher in the households of cases in which the incidence of maternal smoking was significantly higher than that of paternal smoking. Children in this group were more affected by maternal smoking and by the total number of cigarettes smoked inside the house. Additionally, the questionnaire results indicated that the risk of wheezing was dose dependent. The presence of allergic components, such as atopic dermatitis and siblings with allergic rhinitis and asthma, greatly increased the odds ratio when wheezing was associated with cotinine levels. CONCLUSION: Children exposed to tobacco smoke have an increased risk of developing wheezing syndrome. This risk increases in association with the number of cigarettes smoked inside the house and the presence of other allergic components in the family.

Abstract
Solid-phase microextraction coupled with gas chromatography and mass spectrometry (SPME-GC-MS) was developed for the study of interactions between polycyclic aromatic hydrocarbons (PAHs) and dissolved organic matter (DOM). After the determination of the best conditions of extraction, the tool was applied to spiked water to calculate the dissolved organic carbon water distribution coefficient (K(DOC)) in presence of different mixtures of PAHs and Aldrich humic acid. The use of deuterated naphthalene as internal standard for freely dissolved PAH quantification was shown to provide more accuracy than regular external calibration. For the first time, K(DOC) values of 18 PAHs were calculated using data from SPME-GC-MS and fluorescence quenching; they were in agreement with the results of previous studies. Competition between PAHs, deuterated PAHs and DOM was demonstrated, pointing out the non-linearity of PAH-DOM interactions and the stronger interactions of light molecular weight PAHs (higher K(DOC) values) in absence of high molecular weight PAHs.

Abstract
OBJECTIVES: Escherichia coli producing CTX-M-15 and CTX-M-14 extended-spectrum beta-lactamases (ESBLs) are spreading worldwide. The aim of this work was to investigate the replicons involved in the emergence and spread of ESBLs in relation to ESBL type. METHODS: A collection of 125 TEM, SHV and CTX-M ESBL-producing E. coli strains was analysed. The replicons carrying the ESBLs and the total plasmid content of the strains have been characterized by PCR replicon typing in relation to the type of ESBL. The ESBL replicons were then compared with the replicon content of E. coli strains carrying TEM-1 or inhibitor-resistant TEM (IRT) beta-lactamases. RESULTS: IncF plasmids were the most frequently carried replicons in our collection, but none carried TEM ESBL. Of TEM ESBLs, 67% were carried on IncA/C replicons except for TEM-52 genes, which were carried preferentially on IncI1 replicons. Although CTX-M enzymes can be carried by various replicons, the great majority of genes encoding CTX-M-14 and CTX-M-15 ESBLs were carried by IncF replicons, as were TEM-1 and IRT beta-lactamases. CONCLUSIONS: Resistance genes borne by the narrow host-range IncF replicon spread readily as this replicon is well adapted to E. coli. This is observed for blaTEM-1 and blaCTX-M-15 and, to a lesser extent, for blaCTX-M-14. Transposition immunity seems to play an important role in the diffusion process.

Abstract
OBJECTIVES: Escherichia coli producing CTX-M-type extended-spectrum beta-lactamases (ESBLs) are spreading worldwide. The aim of this work was to investigate the addiction systems carried by the replicons involved in the emergence and spread of ESBLs in relation to ESBL and replicon types. METHODS: A collection of 125 TEM, SHV and CTX-M ESBL-producing E. coli isolates and their 125 transconjugants or transformants was analysed. Five plasmid protein antitoxin-regulated systems and three plasmid antisense RNA-regulated systems were sought by PCR. RESULTS: Two hundred and ninety-eight plasmid addiction systems were detected in the parental strains (mean 2.38, range 0-6 per strain) and 86 were detected in the recipient strains (mean 0.69, range 0-5 per strain). PemKI, CcdAB, Hok-Sok and VagCD were the most frequently represented systems in both recipient and parental strains. The parental SHV and CTX-M ESBL-producing strains had more addiction systems than the TEM ESBL producers. In the recipient strains, the frequency of addiction systems was significantly higher in IncF plasmids. Among the IncF replicons carrying CTX-M-type enzymes, the frequency of addiction systems was significantly higher in IncF plasmids carrying CTX-M-15 (mean 3.5) or CTX-M-9 (mean 4) than in those carrying CTX-M-14 (mean 0.6). CONCLUSIONS: In E. coli producing CTX-M-15 or CTX-M-9 ESBLs, plasmids bearing the bla(CTX-M) gene have multiple addiction systems that could contribute to their maintenance in host strains.

Abstract
Curie point pyrolysis gas chromatography-mass spectrometry (Py-GC-MS) has been compared with classical extraction procedures (Soxhlet, sonication, KOH digestion, microwave-assisted) followed by GC-MS analysis for the determination of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil. In each case, the efficiency of the technique was examined for 16 PAHs included in the US Environmental Protection Agency Priority Pollutant List. The results indicate that the recovery of PAHs is dependent on the extraction technique. The highest recoveries of PAHs were obtained with Curie point pyrolysis and KOH digestion. Py-GC-MS appeared to be interesting alternative method for the determination of PAHs in contaminated soil. The results were validated by certified soil (CRM 104) analysis.

Abstract
BACKGROUND: Since 2007, there has been a rise in the use of electronic cigarettes (e-cigarettes). The present study uses cross-sectional data (2013) to examine prevalence, correlates and susceptibility to e-cigarettes among young adults. METHODS: Data were collected using an Internet survey from a convenience sample of 1437, 18-23 year olds attending four colleges/universities in Upstate New York. Results were summarized using descriptive statistics; logistic regression models were analyzed to identify correlates of e-cigarette use and susceptibility to using e-cigarettes. RESULTS: Nearly all respondents (95.5%) reported awareness of e-cigarettes; 29.9% were ever users and 14.9% were current users. Younger students, males, non-Hispanic Whites, respondents reporting average/below average school ability, ever smokers and experimenters of tobacco cigarettes, and those with lower perceptions of harm regarding e-cigarettes demonstrated higher odds of ever use or current use. Risky behaviors (i.e., tobacco, marijuana or alcohol use) were associated with using e-cigarettes. Among never e-cigarette users, individuals involved in risky behaviors or, with lower harm perceptions for e-cigarettes, were more susceptible to future e-cigarette use. CONCLUSIONS: More e-cigarette users report use of another nicotine product besides e-cigarettes as the first nicotine product used; this should be considered when examining whether e-cigarette use is related to cigarette susceptibility. Involvement in risky behaviors is related to e-cigarette use and susceptibility to e-cigarette use. Among college students, e-cigarette use is more likely to occur in those who have also used other tobacco products, marijuana, and/or alcohol.
