Abstract
AIMS: Increasingly popular electronic cigarettes (e-cigarettes) may be the most promising development yet to end cigarette smoking. However, there is sparse evidence that their use promotes cessation. We investigated whether e-cigarette use increases smoking cessation and/or has a deleterious effect on quitting smoking and motivation to quit. METHODS: Representative samples of adults in 2 US metropolitan areas were surveyed in 2011/2012 about their use of novel tobacco products. In 2014, follow-up interviews were conducted with 695 of the 1,374 baseline cigarette smokers who had agreed to be re-contacted (retention rate: 51%). The follow-up interview assessed their smoking status and history of electronic cigarette usage. Respondents were categorized as intensive users (used e-cigarettes daily for at least 1 month), intermittent users (used regularly, but not daily for more than 1 month), and non-users/triers (used e-cigarettes at most once or twice). RESULTS: At follow-up, 23% were intensive users, 29% intermittent users, 18% had used once or twice, and 30% had not tried e-cigarettes. Logistic regression controlling for demographics and tobacco dependence indicated that intensive users of e-cigarettes were 6 times more likely than non-users/triers to report that they quit smoking (OR: 6.07, 95% CI = 1.11, 33.2). No such relationship was seen for intermittent users. There was a negative association between intermittent e-cigarette use and 1 of 2 indicators of motivation to quit at follow-up. CONCLUSIONS: Daily use of electronic cigarettes for at least 1 month is strongly associated with quitting smoking at follow-up. Further investigation of the underlying reasons for intensive versus intermittent use will help shed light on the mechanisms underlying the associations between e-cigarette use, motivation to quit, and smoking cessation.

Abstract
OBJECTIVE: To assess behavior change over 12 months in users of e-cigarettes ("vapers"). METHODS: Longitudinal Internet survey, 2011 to 2013. Participants were enrolled on websites dedicated to e-cigarettes and smoking cessation. We assessed use of e-cigarettes and tobacco among the same cohort at baseline, after one month (n=477) and one year (n=367). RESULTS: Most participants (72%) were former smokers, and 76% were using e-cigarettes daily. At baseline, current users had been using e-cigarettes for 3 months, took 150 puffs/day on their e-cigarette and used refill liquids containing 16 mg/ml of nicotine, on average. Almost all the daily vapers at baseline were still vaping daily after one month (98%) and one year (89%). Of those who had been vaping daily for less than one month at baseline, 93% were still vaping daily after one month, and 81% after one year. In daily vapers, the number of puffs/day on e-cigarettes remained unchanged between baseline and one year. Among former smokers who were vaping daily at baseline, 6% had relapsed to smoking after one month and also 6% after one year. Among dual users (smokers who were vaping daily at baseline), 22% had stopped smoking after one month and 46% after one year. In dual users who were still smoking at follow-up, cigarette consumption decreased by 5.3 cig/day after one month (from 11.3 to 6.0 cig./day, p=0.006), but remained unchanged between baseline and 1-year follow-up. CONCLUSIONS: E-cigarettes may contribute to relapse prevention in former smokers and smoking cessation in current smokers.

Abstract
Escherichia coli cells with autodisplayed Z-domains have been used for immunoassays of specific target analytes. In this study, a magnetite suspension was used for the washing step in immunoassays of E. coli cells with autodisplayed Z-domains. This approach enhanced the washing conditions for these immunoassays by determining (1) the optimal concentration of the magnetite suspension, (2) the capacity of the magnetite suspension-based washing method to recover E. coli cells, and (3) the level at which the activity of autodisplayed Z-domains is maintained. In immunoassays of C-reactive protein (CRP), the immunoassay incorporating the magnetite suspension-based washing method showed a sensitivity and limit of detection considerably higher than those of the conventional centrifugation-based washing method. The results indicated that immunoassays incorporating the magnetite suspension-based washing method are effective for medical diagnoses based on CRP assay.

Abstract
OBJECTIVE: The aim of this study was to use an instrument, the menopause-specific quality-of-life satisfaction in the state of Qatar for the premenopausal, menopause and postmenopausal period. DESIGN: A cross-sectional descriptive study was used to generate menopause symptoms experienced by Arabian Gulf women. Measurement-specific quality-of-life satisfaction questionnaires and face-to-face interviews were performed. SETTING: Primary Health Care (PHC) Centers in Qatar. MATERIALS AND METHODS: A multistage sampling design was used and a representative sample of 1,500 women aged 40-60 years were included during July 2012 and November 2013, and 1,158 women agreed to participate (77.2%) and responded to the study. RESULTS: The mean age and standard deviation of the subjects was 50.9 +/- 6.1. The median age of natural menopause in the present study was 49 years [mean and standard deviation 49.9 +/- 2.7]. The rate of consanguineous marriages in the sample was found to be 30.3%. There were statistically significance differences between menopausal stages with regard to ethnicity, education level, occupation, type of housing condition, and consanguinity. There were statistically significance differences between menopausal stages concerning BMI groups, Systolic BP, Diastolic BP, physical activity, parity, and sheesha smoking habits. Meanwhile, the present study revealed that the most common disease was found to be diabetes mellitus (11.4%), followed by hypertension (6.6%), asthma (5.6%) and CHD (2.5%), and the majority of subjects (69.5%) had no specific disease. The most frequent symptom was aches in the back and neck (49.2%), night sweat (37.2%), low backache (35.7%), feeling nervous (35.4%) followed by aches in the muscles/joints (34.6%), hot flashes (33.3%), decreased social activities (28.3%), decreased leisure activities (47.6%), difficulty sleeping (28.9%), mood swings (25.4%), and decreased concentration (28.3%), sexual activity (24.1%) and total energy level (26.7%). The lowest reported symptoms were facial hair at 16.1% followed by dissatisfied with my personal life at 18.1%. Cronbach's alpha scores, measuring the internal consistency of questions in each domain for physical, vasomotor, psychosocial and sexual were 0.883, 0.853, 0.697 and 0.805, respectively. The Spearman's rank correlation coefficient between domains indicated that there is highly significant concordance between the four domains (P

Abstract
AIMS: To determine, in the context of a trial in which counseling did not improve smoking cessation outcomes, whether this was due to a failure of the conceptual theory identifying treatment targets or the action theory specifying interventions. DESIGN: Data from a randomized clinical trial of smoking cessation counseling and bupropion SR were submitted to multi-level modeling to test whether counseling influenced real-time reports of cognitions, emotions and behaviors, and whether these targets predicted abstinence. SETTING: Center for Tobacco Research and Intervention, Madison, WI. PARTICIPANTS: A total of 403 adult, daily smokers without contraindications to bupropion SR use. Participants were assigned randomly to receive individual counseling or no counseling and a 9-week course of bupropion SR or placebo pill. Cessation counseling was delivered in eight 10-minute sessions focused on bolstering social support, motivation, problem-solving and coping skills. MEASUREMENTS: Pre- and post-quit ecological momentary assessments of smoking behavior, smoking triggers, active prevention and coping strategies, motivation to quit, difficulty quitting and reactions to initial lapses. FINDINGS: Counseling prompted avoidance of access to cigarettes, improved quitting self-efficacy, reduced perceived difficulty of quitting over time and protected against guilt and demoralization following lapses. Results also supported the importance of limiting cigarette access, receiving social support, strong motivation and confidence and easing withdrawal distress during cessation efforts. Quitting self-efficacy and perceived difficulty quitting may partially mediate counseling effects on abstinence. CONCLUSIONS: Smoking cessation counseling may work by supporting confidence about quitting and reducing perceived difficulty quitting. Counseling did not affect other targets that protect against relapse.

Abstract
INTRODUCTION: The purpose of this study was to assess the prevalence of hookah use among Florida high school students over time. Alternative tobacco products, including hookah, pose a public health threat to tobacco prevention efforts, especially among adolescents. METHODS: Florida Youth Tobacco Survey data, representing all public high school students in the state, were analyzed to assess the prevalence of lifetime and current hookah use and were compared by demographic groups. Multiple years of data (2007-2012) were examined to assess changes over time. RESULTS: During the past 6 years, there was an increase in lifetime hookah use among Florida high school students. While males remained at a higher rate overall, female adolescents increased at a faster rate. Hispanic and non-Hispanic White respondents reported increased trends as well. Current use trends did not change over 4 years, remaining at about 8%. CONCLUSIONS: Hookah is a new tobacco product in the United States that appears attractive to youth, with dramatic increases among the state population. While cigarette use among youth is declining in Florida, the increasing uptake of alternative tobacco products may lessen the overall public health gains for tobacco use. There is a need for continued monitoring of hookah use among the adolescent population, for both prevention and cessation efforts as well as policy interventions to address this emerging trend.

Abstract
OBJECTIVES: To examine the prevalence and characteristics of dual users of cigarettes and waterpipes by comparing them with individuals who use either product exclusively. PARTICIPANTS: Cross-sections of undergraduate students at a public university recruited each spring semester from 2006 to 2011 (total N = 2,998). METHODS: Participants completed an Internet survey that assessed demographics, tobacco use, perceptions, and norms concerning various tobacco products. Individuals who reported exclusive cigarette, exclusive waterpipe, and dual (waterpipe + cigarette) use were examined. RESULTS: Across years, 22% reported exclusive cigarette, 6.1% exclusive waterpipe, and 9.3% dual cigarette and waterpipe use. Dual users differed in demographics and social influences from their exclusive counterparts. CONCLUSIONS: Findings suggest that dual waterpipe and cigarette use was more prevalent than exclusive waterpipe use, and dual users may differ from individuals who use either product alone. These results warrant the inclusion of waterpipe-specific content in state and national surveys as well as tobacco prevention and intervention efforts.

Abstract
Water samples were collected from 384 waterworks that supply 70.9% of the Norwegian population. The samples were collected after water treatment and were analysed for 30 constituents. Although most constituents show wide concentration ranges, Norwegian drinking water is generally soft. The median values obtained are: 0.88 mg Si l-1, 0.06 mg Al l-1, 47 μg Fe l-1, 0.69 mg Mg l-1, 2.9 mg Ca l-1, 3.8 mg Na l-1, 6 μg Mn l-1, 12 μg Cu l-1, 14 μg Zn l-1, 9 μg Ba l-1, 15 μg Sr l-1, 0.14 mg K l-1, 58 μg F- l-1, 6.4 mg Cl- l-1, 11 μg Br- l-1, 0.46 mg NO3- l-1, 5.3 mg SO42- l-1, 2.4 mg TOC l-1, 6.8 (pH), 50 μS cm-1 (conductivity) and 11 mg Pt l-1 (colour). Titanium, Pb, Ni, Co, V, Mo, Cd, Be and Li were seldom or never quantified, due to insufficient sensitivity of the ICP (inductively coupled plasma) method. Norwegian quality criteria, which exist for 17 of the constituents examined, are generally fulfilled, indicating that the chemical quality of drinking water, by and large, is good in Norway. For Fe, Ca, Mn, Cu, pH, TOC and colour, however, the norms for good drinking water are exceeded in more than 9% of the samples, reflecting two of the major problems associated with Norwegian drinking water supplies: (i) many water sources contain high concentrations of humic substances; (ii) in large parts of the country, the waters are soft and acidic, and therefore corrosive towards pipes, plumbing and other installations. Most constituents show marked regional distribution patterns, which are discussed in the light of different mechanisms contributing to the chemical composition of drinking water, namely: chemical weathering of mineral matter; atmospheric supply of salt particles from the sea; anthropogenic pollution (including acid precipitation); corrosion of water pipes and plumbing; water treatment; decomposition of organic matter; and hydrological differences.

Abstract
Because of the high stability and potential toxic effects of non-steroidal anti-inflammatory drugs (NSAIDs), it is important to closely monitor their concentrations in the environment using a sensitive analytical method. In this study, a simple, rapid, efficient, and sensitive analytical method based on gas chromatography-mass spectrometry (GC-MS) was developed to determine the levels of seven common NSAIDs in various types of surface water. To simplify sample preparation, in situ derivatization using methyl chloroformate was combined with ultrasound-assisted emulsification microextraction. For selection and optimization of significant variables, experiments were statistically designed using Plackett-Burman design and central composite design. The resulting optimal conditions for derivatization and extraction were 100 muL of chloroform (extraction solvent), 10.0 mL of sample, and 240 muL of pyridine (catalyst as a base in derivatization). The optimized sample preparation coupled with optimized GC-MS analysis in selected ion monitoring mode provided good linearity from 0.010 to 5.0 ng mL(-1), and a limit of detection between 0.0050 and 0.010 ng mL(-1), good intra-day and inter-day precision (0.30-6.3% and 5.1-9.5%, respectively), and good accuracy (relative recovery; 91-117% at 0.20 ng mL(-1) and 77-105% at 2.5 ng mL(-1)). Compared with previously reported methods, the current method requires a small volume of sample and simple sample preparation steps for sensitive determination of NSAID levels using a conventional GC-MS system. The method was successfully applied to determine the levels of seven common NSAIDs in various types of surface water.
