However, information on determinants of GERD from large-scale studies in low- to medium-income countries is limited. We investigated the factors associated with different measures of GERD symptoms, including frequency, patient-perceived severity, and onset time. METHODS: We performed a cross-sectional analysis of the baseline data from a population-based cohort study of approximately 50,000 individuals in in Golestan Province, Iran. GERD symptoms in this study included regurgitation and/or heartburn. RESULTS: Approximately 20% of participants reported at least weekly symptoms. Daily symptoms were less commonly reported by men, those of Turkmen ethnicity, and nass chewers. On the other hand, age, body mass index, alcohol drinking, cigarette smoking, opium use, lower socioeconomic status, and lower physical activity were associated with daily symptoms. Most of these factors showed similar associations with severe symptoms. Women with higher BMI and waist to hip ratio were more likely to report frequent and severe GERD symptoms. Hookah smoking (OR 1.34, 95% CI 1.02-1.75) and opium use (OR 1.70, 95% CI 1.55-1.87) were associated with severe symptoms, whereas nass chewing had an inverse association (OR 0.87, 95% CI 0.76-0.99). After exclusion of cigarette smokers, hookah smoking was still positively associated and nass chewing was inversely associated with GERD symptoms (all frequencies combined). CONCLUSION: GERD is common in this population. The associations of hookah and opium use and inverse association of nass use with GERD symptoms are reported for the first time. Further studies are required to investigate the nature of these associations. Other determinants of GERD were mostly comparable to those reported elsewhere.

The aim of this study is to evaluate the incidence of Legionella spp in water samples collected from 138 dental unit selected from public outpatient clinics of 6 Italian cities. The samples were taken from oral rinsing cup, air-water syringe, ultrasonic scaler and the turbine to investigate Legionella spp, Pseudomonas aeruginosa and the total heterotrophic count at 36 degrees and 22 degrees. Legionella spp was present in 33,3% dental unit water; but a significant difference was shown among the enrolled cities. In 43,5% of water sample Legionella concentration was 1.000-10.000 CFU/L and in 30,4% was >10.000 CFU/L. L. pneumophila 1 was found in 23,9% of water samples. The results demonstrate that the concentration of Legionella spp in dental unit water lines could be high and this suggests that the exposure to these micoorganism during the dental practise could be a potential health risk both for dental personnel and for the patients too, especially when immunocompromised.

The fibers obtained, based on the use of (3-aminopropyl)triethoxysilane and diethoxydiphenylsilane were characterised in terms of film thickness, porosity, thermal stability and pH resistance. An excellent thermal stability was obtained in the case of diethoxydiphenylsilane-based coating, with a negligible weight loss until 400 degrees C. A very good fiber-to-fiber and batch-to-batch repeatability was also obtained with RSD lower than 6% using a mixture of aromatic hydrocarbons in the low ng/l range. Finally, the capabilities of the developed coating for sampling polycyclic aromatic hydrocarbons in water at trace levels were proved obtaining limits of detection about twofold lower than those achieved by using the commercially available polydimethylsiloxane 7 microm fiber.

Twenty-one sampling sites were selected: the pollution produced by the traffic in the vicinity of all exits from the ring road and some access roads to the city, those with higher traffic density, were monitored. Contemporarily the main meteorological parameters (ambient temperature, wind, atmospheric pressure and natural radioactivity) were investigated. It was found that in the same traffic conditions, barriers, buildings and local meteorological conditions can have important effects on the atmospheric dispersion of pollutants. This situation is more critical in downtown where narrow roads and high buildings avoid an efficient dispersion producing higher levels of BTEX. High spatial resolution monitoring allowed both detecting the most critical areas of the city with high precision and obtaining information on the mean level of pollution, meaning air quality standard of the city. The same concentration pattern and the correlation among BTEX levels in all sites confirmed the presence of a single source, the vehicular traffic, having a strong impact on air quality.

Candida sp., associated with many biomaterial-related infections, give rise to infective pathologies typically associated with biofilm formation. We recently determined the in vitro antifungal activities of echinocandin anidulafungin in association with some antifungal drugs against some Candida strains in their planktonic states. A total of 11 Candida strains biofilms were tested in this study: six Candida albicans, three C. parapsilosis and two C. tropicalis. All yeast isolates and ATCC strains were stored at -20 degrees C in glycerol stocks and were subcultured on antimicrobial agent-free Sabouraud dextrose agar plates. MIC endpoints were determined colorimetrically by using the indicator 2,3-bis(2-methoxy-4-nitro-5-sulphophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazoliu m hydroxide (XTT) with menadione as electron-coupling agent. The activity of anidulafungin was assessed using in vitro microbiological model relevant for clinical practice. Anidulafungin showed a strong activity in vitro against both planktonic and biofilms cells, and our study confirms that high anidulafungin concentrations might establish paradoxical growth effect in C. albicans and C. tropicalis biofilms.

Esophageal adenocarcinoma, once an uncommon entity, has been growing rapidly in incidence over the last two decades in several parts of the world. Barrett's esophagus is a change in the esophageal epithelium of any length that can be recognized at endoscopy and is confirmed to have intestinal metaplasia by biopsy (American College of Gastroenterology guidelines). Because of its premalignant nature, it is recommended that patients with BE undergo regular endoscopic surveillance. The recommendation for endoscopic surveillance is based on unproved and controversial assumptions including: 1) the assumption that Barrett's esophagus adversely influences survival; 2) the assumption that endoscopic surveillance can reliably detect early, curable neoplasia in the columnar lined esophagus. Moreover, the low incidence of adenocarcinoma (reported cancer incidence rates in prospective studies on BE range between 0.5% and 1.9%) is used to support an approach of not surveying patients with Barrett's esophagus. Despite these not convincing data, endoscopic surveillance is considered ''reasonable'' and ''desirable'' by the gastroenterological associations and consensus meetings. Endoscopic surveillance for cancer in Barrett's esophagus (BE) is performed primarily to seek dysplasia, to prevent the progression to invasive malignancy; however, one of the limitations of using dysplasia is a lack of understanding of its natural history. The efficacy of endoscopic surveillance for Barrett's esophagus is likely to remain unclear for a long time. The American College of Gastroenterology has recommended the following practice guidelines: a) for patients with no dysplasia, surveillance endoscopy is recommended at an interval of every 2 to 3 years; b) for patients with low grade dysplasia, surveillance endoscopy every 6 months for the first year is recommended, followed by yearly endoscopy if the dysplasia has not progressed in severity; c) for patients with high grade dysplasia, two alternatives are proposed after the diagnosis has been confirmed by an expert gastrointestinal pathologist. One alternative is intensive endoscopic surveillance until intramucosal cancer is detected at an interval of every 3-6 months. The other alternative is esophageal resection. In the situation of indeterminate dysplasia, whereas the pathologist can not come to definite diagnosis, control biopsies are proposed after 2 months of adequate acid suppression by means of proton pump inhibition. In all cases, the technique of random, four quadrant biopsies taken every 2 cm in the columnar-lined esophagus for standard histologic evaluation is recommended. Any grossly abnormal areas may be biopsied too. One can expect however that during the next future these protocol will change considering new data on dysplasia detection (biochemical markers, flow cytometry), new techniques to identify dysplasia (chromoendoscopy, endosonography, coherence optical tomography, fluorescence techniques) and development of better ablative techniques. At present a marker other than dysplasia identifying a high risk group for cancer on which to focus endoscopic surveillance has not yet been established.

Under back-slopping propagation with wheat flour type 0 F114, cell numbers of presumptive lactic acid bacteria varied slightly between and within starters. As determined by randomly amplified polymorphic DNA-PCR and restriction endonuclease analysis-pulsed-field gel electrophoresis analyses, only three (LS8, LS14, and LS44) starters dominated throughout 10 days of propagation. The others progressively decreased to less than 3 log CFU g(-1). Partial sequence analysis of the 16S rRNA and recA genes and PCR-denaturating gradient gel electrophoresis analysis using the rpoB gene allowed identification of Weissella confusa, Lactobacillus sanfranciscensis, Lactobacillus plantarum, Lactobacillus rossiae, Lactobacillus brevis, Lactococcus lactis subsp. lactis, Pediococcus pentosaceus, and Lactobacillus spp. as the dominant species of the raw wheat flour. At the end of propagation, one autochthonous strain of L. sanfranciscensis was found in all the sourdoughs. Except for L. brevis, strains of the above species were variously found in the mature sourdoughs. Persistent starters were found in association with other biotypes of L. sanfranciscensis and with W. confusa or L. plantarum. Sourdoughs were characterized for acidification, quotient of fermentation, free amino acids, and community-level catabolic profiles by USING Biolog 96-well Eco microplates. In particular, catabolic profiles of sourdoughs containing persistent starters behaved similarly and were clearly differentiated from the others. The three persistent starters were further used for the production of sourdoughs and propagated by using another wheat flour whose lactic acid bacterium population in part differed from the previous one. Also, in this case all three starter strains persisted during propagation.

Total microbial community was assessed without cultivation by analyzing DNA directly extracted from the original samples of NWC. In addition, DNA extracted from bulks of cells formed by harvesting colonies from the serial dilution agar plates of a variety of culture media was used to profile the "cultivable" community. The 16S rDNA V3 region was amplified using DNA from NWC as well as DNA from bulks as templates and the amplicons were separated by DGGE. The microbial entities occurring in NWCs were identified by partial 16S rDNA sequencing of DGGE bands: four lactic acid bacteria (LAB) closest relative of Streptococcus thermophilus, Lactococcus lactis, Lactobacillus delbrueckii and Lactobacillus crispatus were revealed by the analysis of DNA directly extracted from NWC while two other LAB, Lactobacillus fermentum and Enterococcus faecalis, were identified by analyzing DNA from the cultivable community. The developed PCR-DGGE analysis of the "cultivable" community showed good potential in evaluating microbial diversity of a dairy environment: it usefully highlighted the bias introduced by selective amplification when compared to the analysis of the total community from NWC and allowed suitability of media and growth conditions to be evaluated. Moreover, it could be used to complete the culture independent study of microbial diversity to give information on concentration ratios among species occurring in a particular environment and can be proposed for rapid identification of dominant microorganisms in alternative to traditional tools.

The proposed investigation strategy compares the chemical information concerning coffee aroma and flavor obtained with HS-SPME of the ground coffee and in-solution SBSE/SPME sampling combined with GC-MS to evaluate their compatibility with the cupping evaluation for quality control purposes. Roasted coffee samples with specific sensory properties were analyzed. The chemical results obtained by the three samplings were compared through multivariate analysis, and related to the samples' sensory attributes. Despite the differences between the three sampling approaches, data processing showed that the three methods provide the same kind of chemical information useful for sample discrimination, and that they could be used interchangeably to sample the coffee aroma and flavor.

The aim of this study was to investigate the microbiota of three Bulgarian boza samples through a combination of culture-dependent and -independent methods with the long-term objective of formulating a multi-strain starter culture specifically destined for the manufacture of new cereal-based drinks. The isolation campaign for lactic acid bacteria (LAB) allowed the identification of Lactobacillus parabuchneri, Lactobacillus fermentum, Lactobacillus coryniformis, Lactobacillus buchneri, Pediococcus parvulus and members of the Lactobacillus casei group. Concerning yeasts, the following isolates were identified: Pichia fermentans, Pichia norvegensis, Pichia guilliermondii (synonym Meyerozyma guilliermondii) and Torulaspora spp. A high intra-species diversity was revealed by Randomly Amplified Polymorphic DNA (RAPD) analysis. In parallel, microbial DNA was directly extracted from the three boza samples, and portions of the rrn operons were analysed through Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis (PCR-DGGE). The molecular fingerprinting partially confirmed the results of culturing. Among LAB, the species Weissella confusa, Weissella oryzae, Leuconostoc citreum, Lactococcus lactis, Pediococcus parvulus and Pediococcus ethanolidurans were detected together with members of the Lb. casei group. Among the yeasts, the species P. fermentans, M. guilliermondii, Galactomyces geotrichum and Geotrichum fragrans were found. The overall results confirmed boza as having a rich and heterogeneous biodiversity both in terms of species and genetically diverse strains, thus encouraging its exploitation for the isolation and future technological characterisation of cultures to be selected for the manufacture of innovative cereal-based drinks.
