Smoking during pregnancy has detrimental effects on asthma-associated outcomes in childhood. Whether passive exposure of pregnant women to ETS may also lead to asthma in their offspring, is not known. The aim of this study was to investigate the association of passive exposure of pregnant women to ETS and asthma- and/or allergy-related symptoms in Preschool children. Cross-sectional data were collected with questionnaires from 2374 Preschool children, recruited from public and private nurseries and day-care centers. Parental smoking was significantly associated with wheezing symptoms in their children. Mother's active smoking during pregnancy significantly increased the risk for occurrence of asthma symptoms and/or medically diagnosed asthma in Preschool children in a dose-dependent manner. Passive exposure to ETS, mainly during the third trimester of pregnancy, was significantly associated with asthma- and allergy-related symptoms after adjusting for several confounders in a multivariate analysis (current wheeze: OR = 1.42, 95% CI = 1.06-1.91, pruritic rash ever: OR= 1.45, 95% CI = 1.01-2.08). Passive exposure of pregnant women to ETS during the third trimester is positively associated with asthma- and allergy-related symptoms in their Preschool age children. Public health policies should be oriented not only towards smoking cessation, but also reinforce elimination of ETS exposure of pregnant women.

OBJECTIVE: To assess perceptions, prevalence and correlates of single cigarette purchase behaviour and its relation to harm reduction. DESIGN: Focus group transcripts and cross-sectional data were analysed. SETTING AND PARTICIPANTS: Focus groups among convenience samples of adult smokers in two Mexican cities and a population-based sample of 1079 adult smokers from the International Tobacco Control Policy Evaluation Project in four Mexican cities. MAIN OUTCOME MEASURES: Purchase of single cigarettes last time cigarettes were bought, frequency of purchasing single cigarettes in the previous month and intention to quit in the next 6 months. RESULTS: Focus group data indicated that smokers bought single cigarettes as a harm reduction strategy. Survey data indicated that 38% of participants purchased single cigarettes in the last month and 10% purchased them the last time they bought cigarettes, with more frequent consumption among young adults and those with lower income. Purchasing single cigarettes was independently associated with the frequency of using single cigarettes to reduce consumption and, less consistently, with the frequency of being cued to smoke after seeing single cigarettes for sale. Using single cigarettes to reduce consumption was positively associated with quit intention, whereas being cued to smoke by single cigarettes was negatively associated with quit intention. CONCLUSIONS: Study results suggest that some adult Mexican smokers purchase single cigarettes as a method to limit, cut down on and even quit smoking. Nevertheless, promotion of the availability of single cigarettes as a harm reduction strategy could provide additional smoking cues that undermine quit attempts and promote youth smoking.

BACKGROUND: Barrett's esophagus is a pre-malignant condition. Surveillance endoscopy (SE) is recommended in order to detect and treat high-grade dysplasia and esophageal adenocarcinoma early and prevent deaths. SE has not been shown to have mortality benefit and several studies have questioned its cost-effectiveness. Most gastroenterology practices do not have a surveillance program for Barrett's esophagus. The few that exist are only in very specialized and funded programs. Little information exists on outcomes in patients with Barrett's esophagus outside of these well-structured surveillance programs. STUDY: A retrospective analysis of a cohort of patients with Barrett's esophagus diagnosed and surveyed between 1995 and 2005 at a Veterans Affairs medical center. Data were collected on age, body mass index, and race. Patients who missed their SE by 6 months or more and those that missed their SE by twice the recommended intervals or more were identified and analyzed for changes in pathologic grades. RESULTS: A total of 472 patients were diagnosed with Barrett's esophagus or had SE between 1995 and 2005. Three hundred and five patients only had one endoscopy and biopsy. They did not have follow-up surveillance endoscopies and biopsies. Two patients were excluded from the final analysis: one had an esophagectomy after an index diagnosis of high-grade dysplasia, and one had a diagnosis of esophageal adenocarcinoma 2 days after an initial impression of Barrett's esophagus. There were 165 patients with Barrett's metaplasia or dysplasia who had SE more than once and were included in the final analysis. Overall, 53.3% had no change in pathologic grade, 35.2% regressed to a lower pathologic grade, and 11.5% progressed to a higher grade. None (0/165, 0%) progressed to esophageal adenocarcinoma; 3.6% (6/165) progressed to high-grade dysplasia and 11.5% (19/165) regressed to normal mucosa. Forty-four patients missed their SE by 6 months or more. Of these, 50% regressed, 40.9% had no change, and 9.1% progressed. Four patients regressed to normal mucosa, one progressed to high-grade dysplasia and none progressed to esophageal adenocarcinoma. Twenty-three patients missed their SE by twice the recommended intervals or more. Of these, 60.9% regressed, 34.8% did not change, and 4.3% progressed. None progressed to esophageal adenocarcinoma or high-grade dysplasia but three regressed to normal mucosa. After adjusting for age and body mass index, patients with low-grade dysplasia are nearly seven times more likely to miss their endoscopy by twice the recommended intervals or more (OR 6.56, P-value 0.03). CONCLUSIONS: Most veteran patients with Barrett's esophagus do not undergo surveillance endoscopies. Veteran patients with Barrett's esophagus undergoing SE rarely progress to high-grade dysplasia or esophageal adenocarcinoma. Veteran patients with Barrett's esophagus who have longer SE up to twice the recommended intervals because they missed their scheduled SE did not have a worse outcome when compared to the general Barrett's esophagus surveillance group. Veteran patients with low-grade dysplasia are most likely to miss their SE by twice the recommended intervals or more, though the reason for this is unknown.

The characteristics and the application of this fiber were investigated. Electron microscope photographs indicated that the MWCNTs/Nafion coating with average thickness of 12.5microm was homogeneous and porous. The MWCNTs/Nafion coated fiber exhibited higher extraction efficiency towards polar aromatic compounds compared to an 85microm commercial PA fiber. SPME experimental conditions, such as fiber coating, extraction time, stirring rate, desorption temperature and desorption time, were optimized in order to improve the extraction efficiency. The calibration curves were linear from 0.01 to 10microgmL(-1) for five PACs studied except p-nitroaniline (from 0.005 to 10microgmL(-1)) and m-cresol (from 0.001 to 10microgmL(-1)), and detection limits were within the range of 0.03-0.57ngmL(-1). Single fiber and fiber-to-fiber reproducibility were less than 7.5 (n=7) and 10.0% (n=5), respectively. The recovery of the PACs spiked in natural water samples at 1microgmL(-1) ranged from 83.3 to 106.0%.

Nine tooth-colored restorative materials were used: three glass ionomers (ceramic-reinforced, resin-modified, and conventional) and six composite resins (nanofilled, ormocer-based, flowable ormocer-based, polyacid-modified, microhybrid, and flowable microhybrid). Disk-shaped specimens were prepared and immersed in 37 degrees C distilled water for 24 hours. Over a 2-week period, five specimens of each material were immersed daily in one of three test beverages (coffee, tea, or cola), then stored in distilled water. A control group of five specimens of each material was continuously immersed in distilled water during the test period. Color coefficients (CIE Lab) were measured by a spectrophotometer before and after staining. All materials were susceptible to staining by all test beverages, while distilled water caused no perceptible color change. As determined by ANOVA and Bonferroni tests, there were highly significant differences in the change in color (deltaE) for tested materials in different beverages (P < or = .001). The deltaE was significantly higher for coffee and tea than for cola; the deltaE was significantly higher for the polyacid-modified composite resin than for all other materials. The material with the least amount of color change in coffee and tea was the ceramic-reinforced glass ionomer (deltaE = 12.45 and 10.64, respectively) and in cola was the nanofilled composite resin (deltaE = 1.93).

The chemical affinity between the ionic liquid (1-octyl-3-methylimidazolium hexafluorophosphate) and the analytes permits the extraction of the PAHs from the sample matrix also allowing their preconcentration. Thus, this technique combines extraction and concentration of the analytes into one step and avoids using toxic chlorinated solvents. The factors affecting the extraction efficiency, such as the type and volume of ionic liquid, type and volume of disperser solvent, extraction time, dispersion stage, centrifuging time and ionic strength, were optimised. Analysis of extracts was performed by high performance liquid chromatography (HPLC) coupled with fluorescence detection (Flu). The optimised method exhibited a good precision level with relative standard deviation values between 1.2% and 5.7%. Quantification limits obtained for all of these considered compounds (between 0.1 and 7 ng L(-1)) were well below the limits recommended in the EU. The extraction yields for the different compounds obtained by IL-DLLME, ranged from 90.3% to 103.8%. Furthermore, high enrichment factors (301-346) were also achieved. The extraction efficiency of the optimised method is compared with that achieved by liquid-liquid extraction. Finally, the proposed method was successfully applied to the analysis of PAHs in real water samples (tap, bottled, fountain, well, river, rainwater, treated and raw wastewater).

The prevalence of using non-assigned treatments is largely unknown although it is likely to be related to the extent to which non-assigned treatments are: (a) easy to find and use, (b) low in cost, (c) well publicized, and (d) available from trusted sources. The impact of using other programs--both beneficial and detrimental--warrants additional research investigation. OBJECTIVE: The aim of this report is to explore the extent to which participants enrolled in a Web-based intervention for smoking cessation used treatment methods that were not explicitly assigned ("non-assigned treatment"). In addition to describing the relation between using non-assigned treatments and smoking cessation outcomes, we also explore the broader issue of non-assigned program use by RCT participants in Web-based behavioral interventions, generally. METHODS: We describe the use of other programs (as measured by self-report at the 3-month follow-up assessment) by 1028 participants who were randomized to the Web-based SHIP (Smokers' Health Improvement Program) RCT which compared the Quit Smoking Network (QSN) treatment program and the Active Lives control condition. We examine the extent to which pharmacotherapy products were used by participants in the QSN condition (which explicitly recommended their use) and the Active Lives condition (which purposefully omitted mention of the use of pharmacotherapy). We also test for any between-condition impact of using non-assigned treatments and pharmacotherapy products on smoking cessation outcomes. RESULTS: A total of 24.1% (248/1028) participants reported using one or more smoking cessation treatment programs that were not explicitly recommended or assigned in their treatment protocol. Types of non-assigned treatments used in this manner included individual counseling (1.7%), group counseling (2.3%), hypnotherapy/acupuncture (4.5%), pamphlets/books (12.6%), and other Web-based smoking cessation programs (9.0%). Participants who used non-assigned treatments were more likely to be female and have at least a high school education. Use of non-assigned Web programs was related to greater levels of self-reported smoking cessation measured at the 3-month assessment (OR = 2.63, CI = 1.67 - 4.14, P < .001) as well as the combined 3- and 6-month assessments (OR = 2.09, CI = 1.11 - 3.91, P = .022). In terms of reported medication use, there were no differences between conditions in the number of pharmacotherapy products used. However, more participants in the QSN condition used at least one pharmacotherapy product: 50.0% (262/524) vs 43.8% (221/504); chi(2)(1, N = 1028) = 3.90, P = .048. The use of pharmacotherapy and non-assigned treatment types showed a small but marginally significant correlation: r(1028) = .061, P = .05. CONCLUSIONS: A noteworthy proportion of individuals recruited via the Internet to participate in a Web-based intervention used treatment programs and tools not formally assigned as a part of their research protocol. We consider factors likely to influence using non-assigned treatments and suggest ways that future research can begin to study more fully this important phenomenon which is likely to be found in any type of research, but may be particularly pronounced in minimal contact, Web-based intervention trials.

METHODS: One thousand consecutive patients with chronic GERD symptoms were included in the study over 2 years. They were subjected to history taking including a questionnaire for GERD symptoms, clinical examination and upper digestive tract endoscopy. Endoscopic signs suggestive of columnar-lined esophagus (CLE) were defined as mucosal tongues or an upward shift of the squamocolumnar junction. BE was diagnosed by pathological examination when specialized intestinal metaplasia was detected histologically in suspected CLE. pH was monitored in 40 patients. RESULTS: BE was present in 7.3% of patients with chronic GERD symptoms, with a mean age of 48.3 +/- 8.2 years, which was significantly higher than patients with GERD without BE (37.4 +/- 13.6 years). Adenocarcinoma was detected in eight cases (0.8%), six of them in BE patients. There was no significant difference between patients with BE and GERD regarding sex, smoking, alcohol consumption or symptoms of GERD. Patients with BE had significantly longer esophageal acid exposure time in the supine position, measured by pH monitoring. CONCLUSION: The prevalence of BE in patients with GERD who were referred for endoscopy was 7.3%. BE seems to be associated with older age and more in patients with nocturnal gastroesophageal reflux.

METHODS: Culture-dependent and -independent (16S rRNA gene clone libraries were constructed) methods were used to determine the composition of LAB in fermented cabbage. RESULTS: Ninety LAB isolated from fermented cabbage were identified as species of Lactobacillus and Leuconostoc, whereas 115 clones of the 16S rRNA gene sequence from fermented cabbage DNA were identified as Lactobacillus, Weissella, Pediococcus and Leuconostoc. CONCLUSION: The significant difference of the LAB compositions by the two methods implies that some specialized nutrients may lead to a distinctive selection of the dominant organisms. Lactobacillus plantarum appeared as the dominant species in fermented cabbage by both methods.
