The aim of our study was to: 1) select an optimal screening method for the detection of PFO; 2) determine the prevalence of PFO in a non-selected population; and 3) test the risk of paradoxical embolization of venous bubbles in patients with PFO. MATERIALS AND METHODS: A diver after decompression is a suitable model for determining the risk of paradoxical embolization of venous gas bubbles. 329 Czech divers were screened for PFO. In a pilot study, we compared Transcranial Doppler Sonography (TCD) with Transesophageal Echocardiography (TEE) in 100 patients. TCD alone was used for further screening. In 31 divers with PFO, nitrogen bubbles were detected after simulated dives. Transthoracic Echocardiography (TTE) was used to detect venous bubbles in right-sided heart chambers; TTE and TCD were used to detect arterial bubbles. The right-to-left shunt was rated as non-significant ( Descriptors Links Book Title Database Publisher Data Source Authors Honek,J., Honek,T., Januska,J., Sebesta,P., Novotny,S., Sefc,L., Fiedler,J., Sramek,M., Horvath,M., Parobkova,M.

We investigated whether tobacco smoking and other factors increase risk for Barrett's esophagus. METHODS: We analyzed data from 5 case-control studies included in the international Barrett's and Esophageal Adenocarcinoma Consortium. We compared data from subjects with Barrett's esophagus (n = 1059) with those from subjects with gastroesophageal reflux disease (gastroesophageal reflux disease controls, n = 1332), and population-based controls (n = 1143), using multivariable logistic regression models to test associations with cigarette smoking. We also tested whether cigarette smoking has synergistic effects with other exposures, which might further increase risk for Barrett's esophagus. RESULTS: Subjects with Barrett's esophagus were significantly more likely to have ever smoked cigarettes than the population-based controls (odds ratio [OR] = 1.67; 95% confidence interval [CI]: 1.04-2.67) or gastroesophageal reflux disease controls (OR = 1.61; 95% CI: 1.33-1.96). Increasing pack-years of smoking increased the risk for Barrett's esophagus. There was evidence of a synergy between ever-smoking and heartburn or regurgitation; the attributable proportion of disease among individuals who ever smoked and had heartburn or regurgitation was estimated to be 0.39 (95% CI: 0.25-0.52). CONCLUSIONS: Cigarette smoking is a risk factor for Barrett's esophagus. The association was strengthened with increased exposure to smoking until approximately 20 pack-years, when it began to plateau. Smoking has synergistic effects with heartburn or regurgitation, indicating that there are various pathways by which tobacco smoking might contribute to development of Barrett's esophagus.

OBJECTIVES: To characterize the relative prevalence of waterpipe tobacco and cigarette smoking among university students in Jordan, and to compare the demographic and environmental factors associated with each form of tobacco use. DESIGN: We surveyed 1845 students randomly recruited from four universities in Jordan. We used multivariable logistic regression controlling for clustering of individuals within universities to determine associations between demographic and environmental covariates and waterpipe tobacco and cigarette use. RESULTS: Waterpipe tobacco smoking rates were 30% in the past 30 days and 56% ever, while cigarette smoking rates were 29% in the past 30 days and 57% ever. Past 30-day waterpipe tobacco smoking rates were 59% for males and 13% for females. Females had substantially lower odds than males of being current waterpipe (OR 0.12, 95%CI 0.10-0.15) or cigarette (OR 0.08, 95%CI 0.05-0.14) smokers. Current cigarette smoking was more significantly associated with markers of high socio-economic status (SES) than waterpipe tobacco smoking. CONCLUSION: Waterpipe tobacco smoking is as common as cigarette smoking among Jordanian university students. While cigarette smoking is consistently associated with high SES, waterpipe tobacco smoking is more evenly distributed across various populations.

We aimed to evaluate esophageal function and the prevalence of GERD and Barrett's esophagus in patients with CIP. GERD is defined by the presence of erosive esophagitis or an abnormal pH monitoring. Seventy-one consecutive patients with endoscopic and histological evidence of CIP were prospectively evaluated. Esophageal symptom analysis, 24-hour simultaneous biliary reflux and double-channel pH-monitoring, and esophageal manometry were carried out in 65/71 (92%) patients and in 25 matched controls. Six patients were not suitable for testing and were, therefore, excluded. The histological evaluation of the heterotopic islands showed cardia and/or oxyntic mucosa in 64/65 (98%) patients and specialized intestinal metaplasia (SIM) in one patient (2%). The cardia and/or oxyntic mucosa was accompanied by focally appearing pancreatic acinar metaplasia and pancreatic ductal metaplasia in 7/64 (11%) and in 1/64 (2%), superficial mucous glands in 6/64 (9%), and SIM in 2/64 (3%) cases. In total, SIM was present in three patients (5%), and one of them had low-grade dysplasia. At the gastroesophageal junction, 28 (43%) patients had columnar metaplasia, including nine (14%) patients with SIM. Erosive esophagitis was present in 37 (57%) cases. Thirty-two patients (49%) had abnormal acid reflux in the distal and 25 (38%) in the proximal esophagus. Abnormal biliary reflux was present in 25 (38%) cases. On the basis of endoscopic and pH studies, GERD was established in 44/65 (68%) patients. Typical reflux symptoms were common (33/65, 51%). The combined 24-hour biliary and double-channel pH-monitoring detected significantly more significant acidic reflux at both measurement points and significantly longer bile exposure time in the distal esophagus in patients with CIP. Acid secretion in the CIP was detected in three (5%) cases. Esophageal manometry revealed decreased LES pressure and prolonged relaxation with decreased peristaltic wave amplitude, and an increased number of simultaneous contractions in the esophageal body. The detailed evaluation of the esophageal morphology and function in subjects with CIP showed a high prevalence of GERD and Barrett's esophagus. Further studies are needed to evaluate whether combined acidic and biliary reflux is able to promote similar histomorphological changes in the CIP, as it is shown distally in patients with Barrett's esophagus.

MATERIALS AND METHODS: Study includes 151 hospitality venues (restaurants, cafes, bars and tea-houses) at eight provinces of Turkey. PM2.5 measurements were done at each of the venues three months prior to, and 4-5 months after the implementation of smoking ban at the same venues. Measurements were done using SidePak 2.5 by two engineers. During the 30 minutes of measurement, the device takes multiple samples, measures PM2.5 particles, and calculates the average value and standard deviation of the measurements. RESULTS: Using the measurement results two kinds of evaluation were done: in each province, increase/decrease after implementation for each of the venues included in the study was evaluated, and average PM2.5 values were calculated for provinces using the PM2.5 values of the venues in the province. The average PM2.5 values before the implementation were higher than the post implementation values in general. Nevertheless, in some provinces higher values were found during the second measurements, particularly at the restaurants. CONCLUSION: Therefore, there is need to enforce the smoking ban at the hospitality workplaces. Descriptors Links Book Title Database Publisher Data Source Authors Bilir,N., Ozcebe,H.

Several parameters such as cashew gum concentration and relative oil content in the matrix had their influence on nanogel properties investigated. Nanogels were characterized regarding their morphologies, particle size distributions, zeta potential, Fourier transform infrared spectroscopy and essential oil contents. The release profile was investigated by UV/vis spectroscopy and its efficacy was determined through bioassays. Results showed that samples designed using relative ratios matrix:oil 10:2, gum:chitosan 1:1 and 5% gum concentration showed high loading (11.8%) and encapsulation efficiency (70%). Nanogels were found to exhibit average sizes in the range 335-558 nm. In vitro release profiles showed that nanoparticles presented slower and sustained release. Bioassays showed that larval mortality was related mainly to oil loading, with samples presenting more effective larvicide efficacies than the pure L. sidoides oil.

METHODS: Hospitality venues were prospectively assessed for their indoor concentrations of particulate matter (PM(2.5)) during the partial ban phase (n=149) and the complete ban phase (n=120, 80% followed up), while overall and matched by venue comparisons were also performed (no ban vs. partial ban vs. complete ban). Comparisons with previously collected data in 2006 when no ban was in place also was performed. RESULTS: Indoor air levels of PM(2.5) attributable to SHS dropped following the transition from a partial to a complete ban by 34% (137 mug/m(3) vs. 90 mug/m(3), p=0.003). This drop was larger in bars (from 195 mug/m(3) to 121 mug/m(3)), than in cafes (124 mug/m(3) vs. 87 mug/m(3)) or restaurants (42 mug/m(3) vs. 39 mug/m(3)). PM(2.5) concentrations between 2006 (no ban) and the partial ban of 2010 were also found to decrease by 94 mug/m(3); however, among matched venues, the levels of indoor air pollution were not found to change significantly (218 mug/m(3) vs. 178 mug/m(3), p=0.58). Comparing the 2010 complete ban results (n=120) with previously collected data from 2006 when no ban was in place (n=43), overall PM(2.5) concentrations were found to fall from 268 mug/m(3) to 89 mug/m(3), while a matched analysis found a significant reduction in PM(2.5) concentrations (249 mug/m(3) vs. 46 mug/m(3), p=0.011). CONCLUSION: The complete ban of smoking in hospitality venues in Greece led to a reduction in SHS exposure, in comparison to when the partial ban or no ban was in place; however, exposure to SHS was not eliminated indicating the need for stronger enforcement.

In this approach, a polyethylene Pasteur squeeze-type pipette was employed as a convenient extraction device and ultrasound radiation was applied to accelerate the emulsification of low-density organic solvent in aqueous solutions to enhance the microextraction efficiency of OCPs in water samples. Thirty microliters of extraction solvent (isooctane), of lower density than water, were injected into the aqueous sample solution held in the pipette. The latter was then immersed in an ultrasound water bath to form an emulsion. After 30s extraction, phase separation was achieved by centrifugation. The upper layer (isooctane) was collected and analyzed by GC-MS. No disperser solvent was required in this procedure. Significantly, fast analysis and high extraction efficiency were achieved. Another feature of the procedure was the use of the pipette as the extraction device, which permitted less dense than water organic solvent to be used as extraction solvent. This method broadens the applicability of USAEME to a wider range of solvent. Additionally, carry-over problems were avoided with the use of the disposable pipette. Parameters affecting the efficiency of polyethylene Pasteur pipette-based USAEME, such as the extraction solvent, extraction solvent volume, extraction and centrifugation time, ionic strength and extraction temperature were investigated. Under the optimum conditions, the proposed method provided good enrichment factors (EFs) in the range of 128 and 328, with relative standard deviations (RSDs) ranging from 2.7% to 12.4%. The limits of detection were in the range of 0.8 and 10ng/L depending on the analytes. The linearities were between 0.01 and 50mug/L for hexachlorobenzene, dieldrin, endrin and o,p'-DDD, 0.05-25mug/L for heptachlor, and 0.005-50mug/L for p,p'-DDE. Finally, the polyethylene Pasteur pipette-based USAEME was successfully used for the fast determination of OCPs in river and tap water samples. The proposed method provides a simple, convenient, rapid, sensitive, cost-effective, and environmentally friendly process for the determination of OCPs in water samples.

Obesity is a significant risk factor for the development of GERD symptoms, erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. Morbidly obese patients who submitted to gastric bypass have an incidence of GERD as high as 50% to 100% and Barrett's esophagus reaches up to 9% of patients. METHODS: In this prospective study, we evaluate the postoperative results after three different procedures--calibrated fundoplication + posterior gastropexy (CFPG), fundoplication + vagotomy + distal gastrectomy + Roux-en-Y gastrojejunostomy (FVDGRYGJ), and laparoscopic resectional Roux-en-Y gastric bypass (LRRYGBP)--among obese patients. RESULTS: In patients with SSBE who submitted to CFPG, the persistence of reflux symptoms and endoscopic erosive esophagitis was observed in 15% and 20.2% of them, respectively. Patients with LSBE were submitted to FVDGRYGJ or LRRYGBP which significantly improved their symptoms and erosive esophagitis. No modifications of LESP were observed in patients who submitted to LRRYGBP before or after the operation. Acid reflux diminished after the three types of surgery were employed. Patients who submitted to LRRYGBP presented a significant reduction of BMI from 41.5 +/- 4.3 to 25.7 +/- 1.3 kg/m(2) after 12 months. CONCLUSIONS: Among patients with LSBE, FVDGRYGJ presents very good results in terms of improving GERD and Barrett's esophagus, but the reduction of weight is limited. LRRYGBP improves GERD disease and Barrett's esophagus with proven reduction in body weight and BMI, thus becoming the procedure of choice for obese patients.

MATERIALS AND METHODS: In this in vitro study forty - eight premolars, extracted for orthodontic purposes were randomly divided in to three groups. Thirty-two teeth were exposed to laser energy for 25 s: 16 teeth at 100 mj setting and 16 teeth at 150 mj setting. Sixteen teeth were etched with 37% phosphoric acid. The shear bond strength of bonded brackets with the Transbond XT adhesive system was measured with the Zwick testing machine. Descriptive statistics, Kolmogorov-Smirnov test, of homogeneity of variances, one- way analysis of variances and Tukey's test and Kruskal Wallis were used to analyze the data. RESULTS: The mean shear bond strength of the teeth lased with 150 mj was 12.26 +/- 4.76 MPa, which was not significantly different from the group with acid etching (15.26 +/- 4.16 MPa). Irradiation with 100 mj resulted in mean bond strengths of 9.05 +/- 3.16 MPa, which was significantly different from that of acid etching (P Descriptors Links Book Title Database Publisher Data Source Authors Raji,S.H., Birang,R., Majdzade,F., Ghorbanipour,R.
