The aim of this study was two-fold; first, to establish the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in chicken production in a region within Romania. Second, to study the relatedness of ESBL-producing E. coli isolates recovered from broilers, abattoir workers where the chickens were slaughtered and from the human clinical specimens from two regional hospitals. The results indicated a very high (69%) rate of carriage of ESBL and AmpC-producing E. coli in chickens with 36% CTX-M producers. Sequencing showed that chickens in Romania have the highest worldwide prevalence (53%) of blaCTX-M-15 reported in poultry E. coli isolates. The majority (53%) of the extended-spectrum cephalosporin-resistant E. coli carried plasmid-mediated blaampC genes, mostly blaCMY-2 type, one of the highest prevalences reported in Europe. The predominant CTX-M type found in the human clinical E. coli isolates was blaCTX-M-15 and most isolates coharbored blaOXA-1, blaTEM, and aac(6')-ib-cr. The majority (60%) of the human clinical isolates belonged to the pandemic virulent clone B2-ST131. The clonal relationship between broiler and the human CTX-M-producing E. coli isolates was assessed by macrorestriction pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST), which indicated strain diversity with no common STs found between human and poultry isolates. Moreover, IncI1 was the most prevalent replicon found in broiler ESBL-producing E. coli isolates and also in transconjugants, indicating that plasmids and not clonal spread may play a role in the transfer of blaCTX-M genes. This study identifies a high prevalence of ESBL-producing E. coli from broiler chickens in Romania with a high occurrence incidence of blaCTX-M-15, which reflects the main ESBL type found in human E. coli infections in this country.

This paper is the first to report population-based data on ever-use and current use of e-cigarettes among New Zealand adults. The paper also extends previous international studies by exploring the reasons for trying e-cigarettes, ever users' recall of brand(s) they have ever tried, and current users' recall of their current brand. METHODS: The Health and Lifestyles Survey (HLS) is a biennial face-to-face in-house survey of New Zealand adults aged 15 years or over. In 2014, 2594 participants completed the survey. RESULTS: Ever-use and current use of e-cigarettes were 13.1% and 0.8% respectively. Tobacco smoking status predicted the use of e-cigarettes, with current smokers reporting the highest rate of use (50% ever-use and 4% current use). Among current smokers who had tried an e-cigarette, curiosity (49%) and desire to quit smoking (37%) were the most common reasons for trying. About half of the ever-users could not name any of the brand(s) they had ever tried, and one-fifth of current users could not name their current brand. CONCLUSIONS: Compared with other countries, New Zealand has a high rate of ever-use. Among current smokers, one in two had tried an e-cigarette. However, progression to regular use appears to be rare. The finding that 18% of current e-cigarette users could not name their current brand highlights the importance of investigating users' knowledge of e-cigarettes in general and assessing the factors that influence brand choice such as advertising, price, and accessibility.

This study examines differences in nicotine dependence among menthol and non-menthol daily smokers and the associations of nicotine dependence with quitting behaviors among Native Hawaiian, Filipino, and White cigarette smokers aged 18-35. METHODS: Craigslist.org, newspaper advertisements, and peer-to-peer referrals were used to recruit daily smokers (n = 186) into a lab-based study. Nicotine dependence was assessed using the Fagerstrom Test of Nicotine Dependence (FTND), the Nicotine Dependence Syndrome Scale (NDSS), and the brief Wisconsin Inventory for Smoking Dependence Motives (WISDM). Multiple regression analyses were used to examine differences in nicotine dependence between menthol and non-menthol smokers and the relationship between each nicotine dependence scale with self-efficacy to quit, quit attempt in the past 12 months, and number of attempts. RESULTS: Menthol smokers were more likely to report difficulty refraining from smoking in places where forbidden (p = .04) and had higher scores on social/environmental goads subscale of the WISDM (p = .0005). Two-way interaction models of the FTND and menthol status showed that menthol smokers with higher levels of dependence were more likely to have tried to quit smoking in the past 12 months (p = .02), but were less likely to have had multiple quit attempts (p = .01). CONCLUSIONS: Components of the FTND and WISDM distinguish levels of dependence between menthol and non-menthol smokers. Higher FTND scores were associated with having a quit attempt, but fewer quit attempts among menthol smokers.

Given overlapping time frames, integrating these services provides an opportunity to leverage existing health visits to offer women more comprehensive services. From March through November 2012, Liberia's government, with support from the Maternal and Child Health Integrated Program (MCHIP), piloted an integrated family planning and immunization model at 10 health facilities in Bong and Lofa counties. Vaccinators provided mothers bringing infants for routine immunization with targeted family planning and immunization messages and same-day referrals to co-located family planning services. In February 2013, we compared service statistics for family planning and immunization during the pilot against the previous year's statistics. We also conducted in-depth interviews with service providers and other personnel and focus group discussions with clients. Results showed that referral acceptance across the facilities varied from 10% to 45% per month, on average. Over 80% of referral acceptors completed the family planning visit that day, of whom over 90% accepted a contraceptive method that day. The total number of new contraceptive users at participating facilities increased by 73% in Bong and by 90% in Lofa. Women referred from immunization who accepted family planning that day accounted for 44% and 34% of total new contraceptive users in Bong and Lofa, respectively. In Lofa, pilot sites administered 35% more Penta 1 and 21% more Penta 3 doses during the pilot period compared with the same period of the previous year, while Penta 1 and Penta 3 administration decreased in non-pilot facilities. In Bong, there was little difference in the number of Penta 1 and Penta 3 doses administered between pilot and non-pilot facilities. In both counties, Penta 1 to Penta 3 dropout rates increased at pilot sites but not in non-pilot facilities, possibly due to higher than average background dropout rates at pilot sites prior to the intervention in Lofa and the disproportionate effect of data from 1 large facility in Bong. The project provided considerable basic support to assess this proof of concept. However, results suggest that introducing a simple model that is minimally disruptive to existing immunization service delivery can facilitate integration. The model is currently being scaled-up to other counties in Liberia, which could potentially contribute to increased postpartum contraceptive uptake, leading to longer birth intervals and improved health outcomes for children and mothers.

Moreover, the occurrence of antibiotic-resistant bacteria in the clinical environment is dramatically growing, making treatment of bacterial infections very challenging. In search of an alternative, we studied a novel antimicrobial surface coating based on micro galvanic elements formed by silver and ruthenium with surface catalytic properties. The antimicrobial coating efficiently inhibited the growth of the nosocomial pathogens Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis and Enterococcus faecium as demonstrated by the growth inhibition on agar surface and in biofilms of antibiotic resistant clinical E. faecalis, E. faecium, and S. aureus isolates. It also strongly reduced the growth of Legionella in a drinking water pipeline and of Escherichia coli in urine. We postulate a mode of action of the antimicrobial material, which is independent of the release of silver ions. Thus, the novel antimicrobial coating could represent an alternative to combat microbial growth avoiding the toxic side effects of high levels of silver ions on eukaryotic cells.

Telephone tobacco quit lines (QLs) are one of the most widely disseminated tools for providing cessation services to cigarette smokers, but the range of QL treatment services offered to non-cigarette TNCP users needs to be determined. METHODS: We surveyed QLs across 50 US states, Washington D.C., and Guam for the number of treatment protocols offered, products they were intended to treat, and how telephone counselors triaged patients reporting the use of non-cigarette TNCPs. RESULTS: Thirteen organizations provided US QL interventions of which eleven agreed to be interviewed regarding their treatment services (84.6%). Seven of the eleven QL providers (63.6%) used a single intervention protocol adapted to the type of non-cigarette TNCP used. Two of the eleven QLs (18.2%) referred hookah users to another provider and one QL (9.1%) referred electronic cigarette users to third party resources for cessation support; otherwise a single intervention protocol was used for all other TNCP users. Only one QL (9.1%) had a specialized protocol for smokeless tobacco users in addition to a standard protocol for all other callers. CONCLUSIONS: QL providers do not have access to tailored protocols for non-cigarette TNCP users, and it remains uncertain whether a common tobacco protocol will be efficacious for these users. Future research should both validate potential common protocols for non-cigarette TNCP users and address the need for and the development of specialized QL interventions for TNCP users to help them quit.

The objectives of this study were to examine the prevalence, patterns and correlates of WTS among students across Lebanon. STUDY DESIGN: The study design was a cross sectional survey. METHODS: 126-item tobacco questionnaire was conducted among 1128 sixth and seventh grade students across Lebanon. Current patterns of use were descriptively analysed, and logistic regression models examined correlates of WTS. RESULTS: Ever WTS prevalence was 44.3%, current WTS prevalence was triple that of cigarettes (22.1% vs 7.4%), and 40.0% of current users were at least weekly or daily smokers. Initiation and patterns of use, as well as addiction and cessation attitudes have been reported. Significant correlates of current WTS included older age, reduced religiosity, peer and parent tobacco use, recent waterpipe advertisement exposure, increased pluralistic ignorance and current cigarette use. Significant correlates of ever WTS were similar to current WTS, but included second hand waterpipe tobacco smoke exposure at home and did not include recent waterpipe advertisement exposure. Neither gender nor socio-economic status were significant correlates of current or ever WTS. CONCLUSIONS: Waterpipe is the most common form of tobacco smoking, and is used regularly, among sixth and seventh grade Lebanese students. It should be considered a public health priority with increased tobacco surveillance and legislation. Widespread educational and policy interventions might help denormalize the social acceptability of WTS. Meanwhile, more research is needed to understand the changing paradigm of WTS epidemiology and the health outcomes among young smokers.

METHODS: Multilevel mixed-effects regressions were performed to assess the relationship between factors that might be associated with e-cigarette, conventional cigarette and dual use in a cohort of 2693 German adolescents (mean age=12.5 years; SD=0.6). Risk factors were assessed in October 2010 and life time e-cigarette and conventional cigarette use were assessed 26 months later. RESULTS: Use of e-cigarettes as well as use of conventional cigarette and dual use were associated with higher sensation seeking scores, and higher odds of having friends and parents who smoke conventional cigarettes, with conventional cigarette use additionally with male gender, being older, having higher odds of siblings who smoke conventional cigarettes, and less likely for adolescents who attend a Gymnasium, secondary school with a strong emphasis on academic learning. The use of conventional cigarettes at baseline did not predict e-cigarette use at follow-up. Lifetime prevalence of e-cigarette use was 4.7%, of conventional cigarette use 18.4%. A quarter of e-cigarette users (23.8%) never smoked a conventional cigarette. DISCUSSION: Data indicate that e-cigarette and conventional cigarette use share many but not all risk factors. E-cigarettes could counteract the process of denormalization of smoking. Descriptors Links Book Title Database Publisher Elsevier Inc Data Source Authors Hanewinkel,R., Isensee,B.

At first, OPPs were ultrasonically leached from soil samples by using methanol. After centrifugation, the separated methanol was diluted to 50 mL with double-distillated water and passed through the C18 SPE cartridge. OPPs were eluted with 1 mL acetonitrile. Thus, 1 mL acetonitrile extract (disperser solvent) and 10 microL 1-undecanol (extraction solvent) were added to 5 mL double-distilled water and a DSLLME technique was applied. The variables of interest in the USL-SPE-DSLLME method were optimized with the aid of chemometric approaches. First, in screening experiments, fractional factorial design (FFD) was used for selecting the variables which significantly affected the extraction procedure. Afterwards, the significant variables were optimized using response surface methodology (RSM) based on central composite design (CCD). Under the optimum conditions, the enrichment factors were 6890-8830. The linear range was 0.025-625 ng g(-1) and limits of detection (LODs) were between 0.012 and 0.2 ng g(-1). The relative standard deviations (RSDs) were in the range of 4.06-8.9% (n=6). The relative recoveries of OPPs from different soil samples were 85-98%.
