Recently, waterpipe smoking has become more popular in many countries. Although the genotoxicity associated with cigarette smoking has been extensively investigated, studies evaluating such toxicity in waterpipe users are still lacking. In this study, we examined the genotoxicity of waterpipe smoking in lymphocytes compared with the genotoxicity of cigarette smoking. Genotoxicity was evaluated using the sister chromatid exchanges (SCEs) assay. Fifty waterpipe smokers and 18 healthy nonsmokers participated in this study. Additionally, 18 heavy cigarette smokers (CS) were recruited for comparison. The results show that waterpipe smoking and cigarette smoking significantly increase the frequencies of SCEs (P Descriptors Links Book Title Database Publisher Wiley-Liss, Inc Data Source Authors Khabour,O.F., Alsatari,E.S., Azab,M., Alzoubi,K.H., Sadiq,M.F.

METHODS: We used data from the 2003 and 2006-2007 waves of the large, nationally representative Tobacco Use Supplement to the Current Population Survey with control for state-level tobacco control spending, prices, and smoke-free air laws. We estimated mean prevalence, quit rates, and multivariate logistic regression equations by using self-respondent weights for menthol and nonmenthol smokers. RESULTS: In 2003 and 2007, 70% of smokers smoked nonmenthol cigarettes, 26% smoked menthol cigarettes, and 4% had no preference. Quit attempts were 4.3% higher in 2003 and 8.8% higher in 2007 among menthol than nonmenthol smokers. The likelihood of quitting was 3.5% lower for quitting in the past year and 6% lower for quitting in the past 5 years in menthol compared with nonmenthol smokers. Quit success in the past 5 years was further eroded among menthol-smoking Blacks and young adults. CONCLUSIONS: Menthol smokers are more likely to make quit attempts, but are less successful at staying quit. The creation of menthol preference through marketing may reduce quit success.

METHODS: A cross-sectional study was conducted from September 2009 to May 2010. An anonymous, self-administered, Global Adult Tobacco Survey based questionnaire was completed by the students attending the main Medical College of King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia. RESULTS: Of the 643 students in the study, 90 students (14%) indicated that they smoked tobacco at the time of the study. The prevalence of smoking was 24.8% among males, and 9.1% among females. Smoking was more common in males (p=0.003), but there were more ex-smokers among females (p=0.042). The friends and parents were considered the primary influence for initiating smoking habit, followed by the media. Ninety percent thought that doctors should set a good example by not smoking. Most of the study population indicated that smoking is related to serious illnesses; however, non-smokers were better aware of such illnesses than smokers. Although most thought that smoking tobacco is harmful, approximately 9.5% believe that smoking a water pipe is not. CONCLUSION: Despite the good knowledge on the hazards of tobacco consumption, 24.8% male, and 9.1% female medical students in Jeddah continue to smoke. The policymakers should address the factors contributing to the initiation, continuation, and spread of this devastating habit.

The apparatus is simple and easy to operate. After manual shaking for 10s, ultrasound was used to accelerate emulsification of the organic solvent (1-decanol) in aqueous solution. Only 10 muL of the low-toxicity extraction solvent is used in this method; no dispersive solvent is required and the total extraction time is approximately 4 min. Manual shaking before ultrasound-assisted emulsification enhances the extraction efficiency by >100%. The effects of horizontal and vertical orientation as well as the location of the sample within the ultrasonic bath were studied. After centrifugation, we used an improved solvent collection system (ISCS) to reduce the amount of extraction solvent required. A 1 muL sample of the extract was injected into the GC column. Under optimum conditions, the linear range of the method is 5-2500 ngL(-1) for most of the OCPs, and the limit of detection of the method ranged from 0.6 to 2.9 ngL(-1).The relative recoveries ranged from 75 to 107% for sea water and from 70 to 99% for field fresh water. The method, which provides good enrichment factors, low LODs and minimization of the consumption of organic solvent, provides a rapid, simple and environment-friendly procedure for determining OCPs in aqueous samples.

A substantial simplification of sample processing prior to quantification step was achieved: after addition of water to homogenized sample, transfer of hydrophobic analytes into ethyl acetate was supported by added inorganic salts. Bulk fat, contained in crude organic extract obtained by partition, was subsequently removed on a silica minicolumn. This approach enabled to process six samples in less than 1h; moreover, the volume of an extraction solvent and consumption of other chemicals can be significantly reduced compared to, e.g., traditional Soxhlet extraction followed by gel permeation chromatography. The recoveries of target analytes were in the range of 73-120% even at the lowest spiking level (1 mug kg(-1)), repeatabilities (relative standard deviations, RSDs) ranged from 1 to 20%. Under optimized GC-MS conditions (time-of-flight mass analyzer, TOF), the limits of quantification (LOQs) were as follows: PCBs 0.1-0.5 mug kg(-1), PBDEs 0.5 mug kg(-1), and PAHs 0.05-0.25 mug kg(-1). Ambient mass spectrometry employing a direct analysis in real time (DART) ion source was shown as an effective tool for fat control in extract, which is needed during the method development and examination of unknown samples prior to the analysis. Further extension of a method scope by other similar analytes is easily possible.

STUDY SELECTION: Articles in any language that assessed the association between water pipe smoking and any health outcome. Included studies were cohort, case-control and cross-sectional. Studies were excluded if they looked at physiological outcomes, non-tobacco pipe use, or didn't differentiate between this and other smoking habits. DATA EXTRACTION AND SYNTHESIS: Data were abstracted independently by two reviewers using a standardised screening guide and GRADE used to evaluate study quality. The I(2) statistic was used to measure heterogeneity. Odds ratios for the effect of pipe smoking on lung, bladder, oesophageal and nasopharyngeal cancer, oral dysplasia, pregnancy outcomes, periodontal disease, hepatitis, respiratory illness and infertility were extracted. RESULTS: Twenty-three studies were included. Based on the available evidence, waterpipe tobacco smoking was significantly associated with lung cancer, respiratory illness, low birth-weight and periodontal disease. It was not significantly associated with bladder, nasopharyngeal and oesophageal cancers, neither with oral dysplasia or infertility, but the confidence Intervals (CIs) did not exclude important associations. Smoking a waterpipe in groups was not significantly associated with hepatitis C infection. The overall quality of evidence varied from very low to low. CONCLUSIONS: The evidence from very low to low quality studies is that waterpipe tobacco smoking is possibly associated with a number of deleterious health outcomes including lung cancer, respiratory illness, low birth-weight and periodontal disease.

Few studies have examined berries harvested in winter months from subtropical regions with shorter photoperiods. Fruits harvested in February and March from two strawberry cultivars, 'Strawberry Festival' and 'Florida Radiance', were examined. Thirty odor active compounds were detected using time-intensity GC-O. Twenty-nine were identified. The major odor active volatiles in both cultivars were 2,5-dimethyl-4-methoxy-3(2H)-furanone (DMMF), 2,5-dimethyl-4-hydroxy-3(2H)-furanone (DMHF), methyl butanoate, gamma-decalactone, unknown (grassy, LRI 1362, wax), (E)-2-hexenal, linalool, (E,Z)-2,6-nonadienal, geraniol, butanoic acid, methyl 2-methylbutanoate, and ethyl hexanoate. Over 90 volatiles were identified and 54 quantified using GC-MS including 33 esters, 6 alcohols, 5 acids, 3 aldehydes, 3 lactones, 2 ketones, and 2 furanones. Odor activity values (OAVs) were determined for 46 volatiles, of which 22 had OAV > 1. The highest OAVs for 'Strawberry Festival' were ethyl butanoate (461), DMHF (424), methyl butanoate (358), and linalool (102). A 14-member trained panel evaluated quartered fruit using quantitative descriptive analysis to quantify seven sensory attributes. Sensory "strawberry flavor" scores were positively correlated with sensory "sweetness" (R(2) = 0.83) as well as GC-MS methyl 3-methylbutanoate (R(2) = 0.90) and ethyl butanoate (R(2) = 0.96). These cultivars lacked methyl anthranilate and possessed an aroma pattern different from summer-grown strawberries.

OBJECTIVE: To evaluate the prevalence and determinants of BE in children who are free from neurodevelopmental disorders and tracheoesophageal abnormalities. DESIGN: A prospective, cross-sectional study. SETTING: Three pediatric GI Centers in Houston, Texas; Phoenix, Arizona; and Portland, Maine between February 2006 and December 2007. PATIENTS: This study involved children and adolescents consecutively presenting for elective upper endoscopy. Patients with neurodevelopmental and tracheoesophageal disorders were excluded. INTERVENTION: Endoscopic pictures of all cases with suspected BE were independently reviewed and verified by two experienced investigators. Esophageal biopsy specimens were obtained in all patients, and targeted biopsy specimens also were obtained from suspected BE. MAIN OUTCOME MEASUREMENTS: Endoscopically suspected BE and histologically confirmed BE. RESULTS: A total of 840 patients (mean age 9.5 years) were enrolled and had complete questionnaire and endoscopic data. Twelve patients were suspected of having BE (prevalence of 1.43%; 95% confidence interval [CI], 0.73-2.45), and only 1 patient had intestinal metaplasia, for a prevalence of 0.12% (95% CI, 0-0.65), whereas the rest had gastric oxyntic glands (n=6) or squamous esophageal epithelium (n=5).
