METHODS: In 2014 we conducted a survey of 3319 middle and high school students. RESULTS: Among the students, 56% had tried an electronic cigarette at least once (boys: 59.9%, girls: 49.3%; ranging from 31.3% for the 8th grade students to 66.1% for the 12th grades). However, only 3.4% reported that they used electronic cigarettes every day. Initiation of e-cigarette use in these teenagers was principally due to use by friends or triggered by curiosity and they usually choose fruit or sweet flavours initially. The majority could not give the concentration of nicotine in e-cigarettes that they used. Moreover, 61.5% of the students had ever tried tobacco and 22.3% were daily smokers. Our study found a strong link between vaping and smoking. 80% of the students who had ever tried conventional cigarettes (94% for the daily smokers) had also tried an electronic cigarette, versus 16% of the student who have never smoked. Few students (6.2%) used electronic cigarettes without smoking tobacco too. Usually, they have tried tobacco before trying an electronic cigarette. Only tobacco smokers seem to smoke electronic cigarettes with nicotine. CONCLUSION: Although our study shows that teenagers frequently try electronic cigarettes, it does not prove, for the moment, that vaping itself usually leads to nicotine addiction. However, as most of the teenagers are unable to tell if the electronic cigarette they are testing contains nicotine, it raises the possibility that they could be vulnerable to manipulation by the tobacco industry.

Microbiological analysis of mesu, soidon, soibum and soijim showed the population dominated by lactic acid bacteria (LAB) ranging up to 10(8) cfu g(-1). The phenotypic characterisation of predominant LAB isolated from the fermented bamboo shoot products was based on general morphology, physiological tests, API and Biolog systems. The genotypic characterisation of LAB was based on RAPD-PCR, rep PCR, species-specific PCR techniques, 16S rRNA gene sequencing and DNA-DNA hybridisation. Predominant functional LAB strains associated with the fermented bamboo shoot products were identified as Lactobacillus brevis, Lb. plantarum, Lb. curvatus, Pediococcus pentosaceus, Leuconostoc mesenteroides subsp. mesenteroides, Leuc. fallax, Leuc. lactis, Leuc. citreum and Enterococcus durans.

Acetonitrile was used to extract the analytes from the food matrix before subjecting the samples to liquid-liquid extraction, solid-phase extraction for further clean-up and preconcentration prior to HPLC analysis. Excellent inter-day precision data (n = 10) and intra-day precision data (n = 5) were obtained on a 200 microg/kg spiked sample. The RSD ranged from 0.20% to 2.96% for the inter-day precision tests, and 0.04% to 2.82% for the intra-day precision tests. Accuracy was measured at three concentration levels: 200, 1000, and 2000 microg/kg; recoveries ranged from 86.07% to 114.06%. The excellent validation data suggests that this method can be applied on canned foods for the determination of migration of BPA, BADGE and its derivatives from can coatings into food.

Culture-dependent and independent approaches were used to investigate the microbial community dynamic. The bacterial population ranged from 0.1 to 6.83 log mL(-1). Lactic acid bacteria (LAB) and Bacillus dominated throughout the fermentation process. Representative colonies were grouped by Repetitive Extragenic Palindromic and Polymerase Chain Reaction (Rep-PCR) and by biochemical features. Genera of Lactobacillus, Bacillus, Leuconostoc, Enterococcus, Streptomyces, Enterobacter, Acinetobacter, Escherichia, Cronobacter, and Klebsiella were identified by partial 16S rRNA gene sequence. As shown by Polimerase and Denaturing Gradient Gel Electrophoresis (PCR-DGGE) analysis, uncultivable Bifidobacterium and Propioniobacterium were found throughout fermentation. Uncultured fungi composed the fungal PCR-DGGE profile. The pH values decreased from 5.2 (time 0) to 3.9 at 36 h of fermentation. Ethanol was not found. The lactic acid concentration increased rapidly throughout fermentation until it reached a high final value (1.4 g L(-1)) and the average glycerol content in the beverage was 0.425 g L(-1). Chicha fermentation might be described by the following phenomena: (i) increasing bacterial population, with lactic acid bacteria (LAB) as the largest group detected; (ii) increasing concentrations of lactic and citric acids; and (iii) the final product is characterized by a high content of acids and the absence of ethanol, therefore characterizing rice chicha an acidic and nonalcoholic beverage. First, this study characterizes the microbial population involved in the nonalcoholic fermentation of chicha, which is produced from rice by Amerindians in Brazil. This study is important for promoting the appreciation of and safeguarding this Brazilian indigenous beverage as an immaterial cultural heritage.

For concentrations of between 20 and 300 nl litre-1 there were linear relationships between exposure concentration and O3 uptake rates. Increasing photon flux densities increased rates of photosynthesis and transpiration, the increases being larger in actively growing than dormant seedlings. Physiological condition (dormancy or active growth), species and photo flux density were found in influence O3 flux via their effects on stomatal conductance. Exposure to 80 nl litre-1 O3 resulted in consistent increases of stomatal conductance and there were also indications that water-use efficiency was decreased.

Three solvents, tetrahydrofuran, xylene and methylene chloride were evaluated for extraction efficiency. Methylene chloride extracted more than 97% of the total extractable organotin in two extractions and resulted in the highest recoveries of analytes from all three PVC products. Method detection limits ranged from 0.3 to 0.9 Î¼g alkyltin/g PVC. The mean precision of the method is 6.8% relative standard deviation. Food industry PVC product samples contained between <0.8 and 8751 Î¼g/g octyltins and <0.3 and 4.7Î¼g/g butyltins. Butyltins (<0.9-5985 Î¼g/g) were detected in potable water pipe samples. Pipe used in industrial applications contained both butyl- (13-1501 Î¼g/g) and octyltins (701-3033 Î¼g/g).

We developed a new Web-based self-help intervention based on problem-solving therapy, which may be used for people with different types of comorbid problems: depression, anxiety, and work-related stress. OBJECTIVE: The aim was to study whether a Web-based self-help intervention is effective in reducing depression, anxiety, and work-related stress (burnout). METHODS: A total of 213 participants were recruited through mass media and randomized to the intervention (n = 107) or a waiting list control group (n = 106). The Web-based course took 4 weeks. Every week an automated email was sent to the participants to explain the contents and exercises for the coming week. In addition, participants were supported by trained psychology students who offered feedback by email on the completed exercises. The core element of the intervention is a procedure in which the participants learn to approach solvable problems in a structured way. At pre-test and post-test, we measured the following primary outcomes: depression (CES-D and MDI), anxiety (SCL-A and HADS), and work-related stress (MBI). Quality of life (EQ-5D) was measured as a secondary outcome. Intention-to-treat analyses were performed. RESULTS: Of the 213 participants, 177 (83.1%) completed the baseline and follow-up questionnaires; missing data were statistically imputed. Of all 107 participants in the intervention group, 9% (n = 10) dropped out before the course started and 55% (n = 59) completed the whole course. Among all participants, the intervention was effective in reducing symptoms of depression (CES-D: Cohen's d = 0.50, 95% confidence interval (CI) 0.22-0.79; MDI: d = 0.33, 95% CI 0.03-0.63) and anxiety (SCL-A: d = 0.42, 95% CI 0.14-0.70; HADS: d = 0.33, 95% CI 0.04-0.61) as well as in enhancing quality of life (d = 0.31, 95% CI 0.03-0.60). Moreover, a higher percentage of patients in the intervention group experienced a significant improvement in symptoms (CES-D: odds ratio [OR] = 3.5, 95% CI 1.9-6.7; MDI: OR = 3.7, 95% CI 1.4-10.0; SCL-A: OR = 2.1, 95% CI 1.0-4.6; HADS: OR = 3.1, 95% CI 1.6-6.0). Patients in the intervention group also recovered more often (MDI: OR = 2.2; SCL-A: OR = 2.0; HADS < 8), although these results were not statistically significant. The course was less effective for work-related stress, but participants in the intervention group recovered more often from burnout than those in the control group (OR = 4.0, 95% CI 1.2-13.5). CONCLUSIONS: We demonstrated statistically and clinically significant effects on symptoms of depression and anxiety. These effects were even more pronounced among participants with more severe baseline problems and for participants who fully completed the course. The effects on work-related stress and quality of life were less clear. To our knowledge, this is the first trial of a Web-based, problem-solving intervention for people with different types of (comorbid) emotional problems. The results are promising, especially for symptoms of depression and anxiety. Further research is needed to enhance the effectiveness for work-related stress.

Cultures were performed for four months from 5 L samples of water, collected before and after the ultraviolet treatment at the lamp unit and from two distal points. Irradiation was effective immediately after disinfection (<10 cfu/L), even when the incoming water was highly contaminated. One distal point showed little or no contamination (<10-20 cfu/L), while the other showed little to moderate contamination (<103 cfu/L). We conclude that ultraviolet irradiation is useful to protect the water system in small area; however, because of the lack of residual activity, it should be combined with other methods of disinfection. Maintenance of the water system is also necessary in order to reduce biofilm formation and Legionella recolonization. Â© 2002 The Hospital Infection Society.
