Abstract
Volatile organic compounds (VOC) are identified in natural biofilm established in plastic pipes used at the drinking water supply. Odour potent VOCs such as ectocarpene, dictyopterene A and C′, geosmin, beta-ionone, 6-methyl-5-hepten-2-one, menthol and menthone were prominent compounds in biofilm in the distribution network and at raw water test sites, and are associated with algae and cyanobacteria present in the raw water source. © IWA Publishing 2004.

Abstract
Approximately 40,000 km of the drinking water network in The Netherlands consists of asbestos cement water pipes. The number of fractures in these pipes has increased greatly in recent years. This is due to corrosion of the asbestos cement (AC) which affects the condition of the pipe. Every time a fracture occurs, the question is raised of whether the pipe in question has to be replaced or repaired. A relatively simple destructive technique and non-destructive tests are used on a large scale to assess the condition of the AC pipes in use. Not only is corrosion detrimental to the pipes themselves, it also influences the water quality. Corrosion of the inner walls of cement-containing pipes involves the leaching of hydroxides. This causes pH changes resulting in scaling in water mains and domestic installations. Monitoring techniques have been developed to determine the effects of leaching on water quality. The large-scale use of the relatively simple techniques at water companies increases insight into the condition of the drinking water network, the life expectancy of the pipes and the effects of corrosion on the water quality. Applying these techniques enables those involved to make decisions on pipe replacement and to provide solutions for reducing the effects of leaching.

Abstract
INTRODUCTION: Diving often causes the formation of 'silent' bubbles upon decompression. If the bubble load is high, then the risk of decompression sickness (DCS) and the number of bubbles that could cross to the arterial circulation via a pulmonary shunt or patent foramen ovale increase. Bubbles can be monitored aurally, with Doppler ultrasound, or visually, with two dimensional (2D) ultrasound imaging. Doppler grades and imaging grades can be compared with good agreement. Early 2D imaging units did not provide such comprehensive observations as Doppler, but advances in technology have allowed development of improved, portable, relatively inexpensive units. Most now employ harmonic technology; it was suggested that this could allow previously undetectable bubbles to be observed. METHODS: This paper provides a review of current methods of bubble measurement and how new technology may be changing our perceptions of the potential relationship of these measurements to decompression illness. Secondly, 69 paired ultrasound images were made using conventional 2D ultrasound imaging and harmonic imaging. Images were graded on the Eftedal-Brubakk (EB) scale and the percentage agreement of the images calculated. The distribution of mismatched grades was analysed. RESULTS: Fifty-four of the 69 paired images had matching grades. There was no significant difference in the distribution of high or low EB grades for the mismatched pairs. CONCLUSIONS: Given the good level of agreement between pairs observed, it seems unlikely that harmonic technology is responsible for any perceived increase in observed bubble loads, but it is probable that our increasing use of 2D ultrasound to assess dive profiles is changing our perception of 'normal' venous and arterial bubble loads. Methods to accurately investigate the load and size of bubbles developed will be helpful in the future in determining DCS risk.

Abstract
OBJECTIVES: To determine the prevalence of habitual snoring among a sample of middle-aged Saudi adults, and its potential predictors. METHODS: A cross-sectional study was conducted from March 2013 until June 2013 in randomly selected Saudi Schools in Jeddah, Kingdom of Saudi Arabia. The enrolled subjects were 2682 school employees (aged 30-60 years, 52.1% females) who were randomly selected and interviewed. The questionnaire used for the interview included: the Wisconsin Sleep Questionnaire to assess for snoring, medical history, and socio-demographic data. Anthropometric measurements and blood pressure readings were recorded using standard methods. RESULTS: Forty percent of the 2682 enrolled subjects were snorers: 23.5% were habitual snorers, 16.6% were moderate snorers, and 59.9%, were non-snorers. A multivariate analysis revealed that independent predictors of snoring were ageing, male gender, daytime sleepiness, hypertension, family history of both snoring and obstructive sleep apnea, water-pipe smoking, and consanguinity. CONCLUSION: This study shows that snoring is a common condition among the Saudi population. Previously reported risk factors were reemphasized but consanguinity was identified as a new independent predictive risk factor of snoring. Exploring snoring history should be part of the clinical evaluation.

Abstract
Smokers need new products and policies to escape smoking's risks. And the next generation needs policies that will better protect them from becoming smokers. Low-nitrosamine tobacco snuff (hereafter termed 'snuff') is 20 times less dangerous than cigarette smoking. Its sale as nasal snuff raises the question as to how long cigarettes, including cigars and pipe tobacco, should continue to be sold and allowed to hasten the deaths of 4000 New Zealanders annually. Oral snuff has helped to reduce smoking to unusually low levels in Swedish men, is much less dangerous than smoking, and does not cause lung or mouth cancer. Moreover, smokeless tobacco (which includes snuff) could reduce smoking-caused health inequity for Maori. Snuff can improve population health, and more so if more smokers switch to it. Continued bans on snuff are now regarded by some experts as unsound public policy. Added to the mountain of evidence against cigarettes, sufficient evidence now exists for Government to use snuff to create safer tobacco choices for smokers, end cigarette sales altogether, and thus end the cigarette smoking deaths epidemic--in which 200,000 New Zealanders have died so far. The New Zealand Government can: Fund media campaigns to inform smokers of their new choices, and to urge them to quit smoking. (The 2007 Budget commits an extra $11 million per year for 4 years, an excellent start.) Regulate for warnings on snuff cans stating that snuff is "addictive but much safer than smoking", and regulate imports to only permit reduced-risk low-nitrosamine products. Tax each class of tobacco products proportionate to the respective risks of each. (Tax cigarettes at 20 times the snuff rate, instead of at the same rate.) Legislate, to expand the Smoke-free Environments Act's aims to include ending the sale of cigarettes and ending smoking deaths--i.e: Allow oral snuff to compete with cigarettes for market share (and for the smoker's nicotine receptors). Reduce addiction to smoking, by decreasing the nicotine content of cigarettes by 5% every 6 months. (Below 20% of current levels, most smokers will quit or switch to snuff.), Allot cigarette supply quotas to manufacturers and importers, decreasing by 5% every 6 months, on the grounds that cigarette smoke is irremediably toxic. The summed effects of these changes could end cigarette sales within 10 years, and prevent 90% of cigarette deaths within 22 years thereafter.

Abstract
OBJECTIVE: To determine the feasibility of implementing cessation interventions in Syria. 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.

Abstract
OBJECTIVES: This study aims to examine current hookah users' perceptions, attitudes, and normative beliefs regarding hookah smoking to further elucidate the rise in hookah smoking prevalence among young adults (aged 18-24 years) and reveal why hookah smoking is perceived as less harmful than other forms of tobacco consumption. STUDY DESIGN: Qualitative. METHODS: Data from six focus group interviews with hookah smokers aged between 18 and 24 years were analyzed using a grounded theory approach. Focus groups were evenly split between frequent and infrequent hookah users, and were predominantly composed of college students, with two groups of hookah users consisting of 18-24 year olds of non-student status. RESULTS: Hookah users shared a much larger set of positive hookah smoking behavioral beliefs as opposed to negative behavioral beliefs. Generational traits served as the overarching commonality among the behavior performance initiation determinants observed. The most notable generational trends observed were within the cultural category, which included the following millennial characteristics: autonomy, personalization, novelty appeal, convenience, globally oriented, entertainment, collaboration, health conscious, and valuing their social network. CONCLUSIONS: Millennial hookah users revealed mindfulness regarding both potential negative and positive reasons stemming from continued hookah use; however, behavioral beliefs were primarily fixated on the perception that hookah smoking was a healthier alternative to cigarette smoking. Future implications for this study's findings include generating more positive ways to express these traits for young adults; policy implications include raising hookah bar age limits, implementing indoor smoking restrictions, and limiting the ease of accessibility for purchasing hookah supplies.

Abstract
BACKGROUND: Stomach cancer is the fourth most common cancer and the second leading cause of death from cancer in the world. In Iran, this type of cancer has high rates of incidence and mortality. This study aimed to assess the survival rate of patients with stomach cancer and its determinants in Kurdistan, a province with one of the highest incidence rates of stomach cancer in the country. MATERIALS AND METHODS: We studied a total of 202 patients with stomach cancer who were admitted to Tohid Hospital in Sanandaj from 2009 to 2013. Using KaplanMeier nonparametric methods the survival rate of patients was calculated in terms of different levels of age at diagnosis, gender, education, residential area, occupation, underweight, and clinical variables including tumor histology, site of tumor, disease stage, and type of treatment. In addition, we compared the survival rates using the logrank test. Finally, Cox proportional hazards regression was applied using Stata 12 and R 3.1.0 software. The significance level was set at 0.05. RESULTS: The mean age at diagnosis was 64.7 +/- 12.0 years. The survival rate of patients with stomach cancer was 43.9% and 7% at the first and the fifth year after diagnosis, respectively. The results of logrank test showed significant relationships between survival and age at diagnosis, education, disease stage, type of treatment, and degree of being underweight (P

Abstract
PURPOSE: The recent legalization of nonmedical marijuana use in several U.S. states has unknown implications for those who are actively parenting. This study examined parents' reactions to marijuana legalization and changes in attitudes and behaviors over time. METHODS: Data were from a gender-balanced, ethnically diverse sample of 395 parents in Washington State who were participating in the longitudinal Seattle Social Development Project. Participants were interviewed 15 times between 1985 (age 10) and 2014 (age 39). Adult nonmedical marijuana use was legalized in Washington in 2012 and retail outlets opened in 2014. RESULTS: Results showed (1) one third of parents incorrectly believed the legal age of nonmedical marijuana use to be 18; (2) significant increase in approval of adult marijuana use and decrease in perceived harm of regular use; (3) wide opposition to teen use and use around one's children; and (4) substantial increases in frequency of use and marijuana use disorder among parents who used. CONCLUSIONS: Despite increased acceptance and frequency of adult use, parents remain widely opposed to teen use but need facts and strategies for talking with their children about marijuana.

Abstract
BACKGROUND: In the 1990s, youth use of alternative tobacco products including cigars, bidis, and kreteks increased. This article discusses the prevalence of youth use of cigars, bidis, and kreteks, and characteristics of users. METHODS: The Cigar Use Reasons Evaluation (CURE)-a questionnaire assessing alternative tobacco use and associated attitudes and behaviors-was administered to middle and high school students from 12 school districts across Massachusetts. RESULTS: Males were more likely to use all forms of alternative tobacco and females more likely to smoke cigarettes. Hispanics were less likely to smoke kreteks or use smokeless tobacco. Urban students were more likely to smoke bidis or use smokeless tobacco than suburban or rural youth. Most smokeless and alternative tobacco users were lifetime cigarette smokers. There was, however, a significant group of cigar smokers, associated with higher parental education, who were not current cigarette smokers. CONCLUSIONS: Use of alternative tobacco poses a risk to the success of tobacco control efforts. While many alternative tobacco users smoke cigarettes, some alternative tobacco users are current cigarette smokers. Cigar use thus constitutes a potential serious risk for youth who otherwise might not be exposed to tobacco.
