None of the planktonic cultures (exponential or stationary phase) contained persister cells. However, persisters were found in biofilms of one of two strains of Candida albicans tested and in biofilms of Candida krusei and Candida parapsilosis, but not in biofilms of Candida glabrata or Candida tropicalis. These results suggest that persister cells cannot solely account for drug resistance in Candida biofilms.

METHODS: A cross-sectional, school-based study was conducted in 2003 involving 9 regions of Oman, as part of the Global Youth Tobacco Survey. Participants were requested to complete an anonymous questionnaire containing demographic characteristics, current and previous use of waterpipe tobacco, attitudes towards cigarette smoking, parents' and friends' cigarette smoking habits. Proportions were used to calculate prevalence rates and logistic regression analysis to obtain odds ratio (OR) and 95% confidence interval (CI). RESULTS: 1,962 students participated of whom 1,005 (51.2%) were males. Eighty-eight percent were between 13 and 16 years of age. Five hundred and twenty-two (26.6%) reported ever smoking waterpipe tobacco while 189 (9.6%) were current users. Among males, 155 (15.5%) were current users while among females only 24 (2.6%) smoked currently. Study participants were more likely to use waterpipe if they had a parent or friend who smoked cigarettes. Adolescents were, however, less likely to use waterpipe tobacco if they believed that cigarette smoking was harmful to health. Students who were receiving 500 Baisas (US$ 1.3) or more per day pocket money were more likely to use waterpipe tobacco compared to those receiving less (OR 3.3, 95% CI 2.3 to 4.6). In multivariate analysis, the OR for males being a smoker of waterpipe tobacco compared to females was 4.46 (95% CI, 2.38 to 8.35); while the OR for most or all friends smoking cigarettes compared to non-smoking was OR 5.65 (95% CI 2.87 to 11.13). Study participants who perceived smoking as harmful to health were less likely to use waterpipe tobacco compared to those who did not believe smoking was harmful (OR 0.31, 95% CI 0.29 to 0.92) and those receiving 500 Baisas or more (OR 2.2, 95% CI 1.5 to 3.2). CONCLUSION: Waterpipe smoking among Omani adolescents is an emerging public health concern. Efforts to prevent adolescent smoking should be designed with knowledge of associated factors of such behaviour and should include all forms of tobacco.

METHODS: A cross-sectional study of a random sample of 570 medical students (first and fifth year) registered at the Damascus University Faculty of Medicine in 2006-2007. We used a self-administered questionnaire for demo-graphic information, smoking behaviour (cigarette, waterpipe), family and peer smoking, attitudes and beliefs about smoking and future role in advising patients to quit smoking. RESULTS: The overall prevalence of tobacco use was 10.9% for cigarettes (15.8% men, 3.3% women), 23.5% for waterpipe (30.3% men, 13.4% women) and 7.3% for both (10.1% men, 3.1% women). Both smoking methods were more popular among the fifth year students (15.4% and 27%) compared to their younger counterparts (6.6% and 19.7%). Regular smoking patterns predominated for cigarettes (62%), while occasional use patterns predominated for waterpipes (83%). More than two thirds of students (69%) thought they might not address or would have difficulty addressing smoking in their future patients. CONCLUSION: The level of tobacco use among Syrian medical students is alarming and highlights the rapidly changing patterns of waterpipe use, especially among female students. Medical schools should work harder to tackle this phenomenon and address it more efficiently in their curricula.

MATERIAL AND METHODS: One hundred and twenty freshly-extracted human teeth were divided into four groups according to how the buccal surface to be bonded had been pre-conditioned: 1) acid-etched with 37% phosphoric acid, 2) sand-blasted with 50 microns aluminum-oxide, 3) matted with diamond burr, and 4) intact enamel used as control. Orthodontic metal brackets were bonded to the teeth using the same composite resin (Transbond XT) and self-etching primer (Transbond Plus Self-Etching Primer). Brackets were debonded within 6 hours or after thermal cycling for 2500 times (5 degrees C--37 degrees C--55 degrees C). Shear bond strength was measured on a testing machine at a crosshead speed of 3 mm/min. The bracket-failure interface was quantified according to the modified adhesive remnant index score (ARI). Data were analyzed using the two-way ANOVA test, Scheffe confidence interval of differences of means, and the chi-square test (p < 0.05). RESULTS: All the pre-conditioned groups showed significantly higher shear bond strength before and after thermal cycling than the control group. There was no significant correlation between thermal cycling and shear bond strength. The ARI scores revealed that the bond failed primarily on the adhesive-enamel interface in all groups before and after thermal cycling, with the exception of the acid-etched group, whose bonds failed mainly on the adhesive-bracket interface after thermal cycling. CONCLUSION: The authors recommend that the enamel be preconditioned before applying the self-etching primer when greater shear bond strength is desired.

However, there is little information on how utilization of specific website features influences quitting. OBJECTIVE: To determine the association between utilization of informational, interactive, and online community resources (eg. bulletin boards) and abstinence rates, with the broader objective to identify potential strategies for improving outcomes for Web-assisted tobacco interventions. METHODS: In Spring 2004, a cohort of 607 quitplan.com users consented to participate in an evaluation of quitplan.com, a Minnesota branded version of QuitNet.com. We developed utilization measures for different site features: general information, interactive diagnostic tools and quit planning tools, online expert counseling, passive (ie, reading of bulletin boards) and active (ie, public posting) online community engagement, and one-to-one messaging with other virtual community members. Using bivariate, multivariate, and path analyses, we examined the relationship between utilization of specific site features and 30-day abstinence at 6 months. RESULTS: The most commonly used resources were the interactive quit planning tools (used by 77% of site users). Other informational resources (ie, quitting guides) were used more commonly (60% of users) than passive (38%) or active (24%) community features. Online community engagement through one-to-one messaging was low (11%) as was use of online counseling (5%). The 30-day abstinence rate among study participants at 6 months was 9.7% (95% Confidence Interval [CI] 7.3% - 12.1%). In the logistic regression model, neither the demographic data (eg, age, gender, education level, employment, or insurance status) nor the smoking-related data (eg, cigarettes per day, time to first morning cigarette, baseline readiness to quit) nor use of smoking cessation medications entered the model as significant predictors of abstinence. Individuals who used the interactive quit planning tools once, two to three times, or four or more times had an odds of abstinence of 0.65 (95% Confidence Interval [CI] 0.22 - 1.94), 1.87 (95% CI 0.77 - 4.56), and 2.35 (95% CI 1.0 - 5.58), respectively. The use of one-to-one messages (reference = none vs 1 or more) entered the final model as potential predictor for abstinence, though the significance of this measure was marginal (OR = 1.91, 95% CI 0.92 - 3.97, P = .083). In the path analysis, an apparent association between active online community engagement and abstinence was accounted for in large part by increased use of interactive quitting tools and one-to-one messaging. CONCLUSIONS: Use of interactive quitting tools, and perhaps one-to-one messaging with other members of the online community, was associated with increased abstinence rates among quitplan.com users. Designs that facilitate use of these features should be considered.

METHODS: A cross-sectional survey of adolescents aged 14-19 years studying at different educational institutions of Karachi, Pakistan was conducted through multistage sampling on a pre-tested self-administered questionnaire. They were divided into high, middle and lower socioeconomic strata on the basis of monthly fee structure. The impact of health messages was assessed two months after education sessions through post-test of only high and middle socioeconomic strata. RESULTS: A total of 646 students were surveyed for the pre test and 250 students for the post test. A significant association was found for water pipe smoking among the socioeconomic class (p < 0.001). Water pipe is more addictive as compared to cigarettes was marked by more students after the sessions (54% vs 68%; p < 0.001). A significant difference was seen for water pipe being more socially acceptable (58% vs 80%; p < 0.001), it is part of our cultural heritage (29% vs 58%; p < 0.001). CONCLUSION: Shisha smoking was more prevalent among the high socio economic group, which might be because of the cost, accessibility and availability. The knowledge of the students regarding water pipe smoking improved after the health awareness sessions.

METHODS: We randomized 50 smokers to either a brief or intensive behavioral cessation intervention. Adherence to treatment and cessation through 3 months postcessation were calculated. RESULTS: Adherence in the intensive group was only moderate and was associated with smoking for more years and higher self-efficacy. Cessation rates in the brief and intensive intervention groups were 16% and 4%, respectively. Nicotine dependence predicted abstinence at 3 months. CONCLUSION: Important barriers to cessation included perceived dependence, lack of access to pharmacotherapy, poor social support, and water pipe smoking.

Smoking profiles of these patients have largely been characterized in small, single-institution cohorts. Our objective was to survey adult smokers visiting a sample of U.S. emergency departments, as part of a study examining the efficacy of an educational intervention on physicians' knowledge, attitudes, and behavior regarding tobacco control. A convenience sample of patients in eight academic emergency departments was surveyed from May to July 2006. Eligible patients were aged 18 years or older, were every- or some-day smokers, spoke English or Spanish, were able to provide written informed consent, and were not actively psychotic. Descriptive statistics are reported using parametric and nonparametric measures. A total of 1,168 patients were interviewed (mean age = 40.7 years); 46.5% were female, 54.4% were uninsured or had Medicaid, and 29.9% had no usual source of care. Patients smoked a median of 10 cigarettes daily, with a median score on the Fagerstrom Test for Nicotine Dependence of 4, and a median score of 5 on the nine-point contemplation ladder, indicating a desire to quit within 6 months. Smokers with a diagnosis of cardiovascular, respiratory, or malignant disease were more interested in quitting than others (median ladder score = 4 vs. 6, p<.001), were more likely to believe they had a smoking-related illness, and were more likely to believe their emergency department visit was related to smoking. Smokers with a presenting complaint of chest pain or dyspnea were more interested in quitting than others (median ladder score = 4 vs. 6, p = .002). Emergency department patients smoked at moderate amounts, with moderate levels of addiction and interest in quitting. Smokers with tobacco-related diagnoses, or who believed their emergency department visit was related to smoking, were more interested in quitting. These findings suggest that the emergency department visit may provide a teachable moment to reach smokers who have tobacco-related problems.

The fibers obtained, based on the use of (3-aminopropyl)triethoxysilane and diethoxydiphenylsilane were characterised in terms of film thickness, porosity, thermal stability and pH resistance. An excellent thermal stability was obtained in the case of diethoxydiphenylsilane-based coating, with a negligible weight loss until 400 degrees C. A very good fiber-to-fiber and batch-to-batch repeatability was also obtained with RSD lower than 6% using a mixture of aromatic hydrocarbons in the low ng/l range. Finally, the capabilities of the developed coating for sampling polycyclic aromatic hydrocarbons in water at trace levels were proved obtaining limits of detection about twofold lower than those achieved by using the commercially available polydimethylsiloxane 7 microm fiber.
