Using the terms 'Barrett's esophagus' and 'Barrett's esophagus, China' as key words, literatures published in Chinese and English journals were searched in Chinese data banks, as well as PubMed and ISI Web of Science from 1989 to 2007. An analysis was carried out with the standard inclusion and exclusion criteria. A total of 4120 cases were included in this study. BE was found in 2.44% of patients undergoing endoscopy for various symptoms of upper gastrointestinal tract diseases; the male : female ratio was 2.09 : 1, the average age of detection of BE was 53.15 years old, and 51% of patients with BE had typical symptoms for gastroesophageal reflux disease (GERD). The island-type BE was predominant (56.80%), and the occurrence of BE with special intestinal metaplasia (SIM) was 36.58%, but SIM was more common in tongue-type BE than island-type and circumferential-type BE (both P < 0.001), as well as in long segment BE (LSBE) than in short segment BE (SSBE) (P < 0.001). A total of 46.39% of patients had Helicobacter pylori infection. The mean length of follow up was 2 years in 492 patients. The incidence of adenocarcinoma was 0.61% patient-years of total follow up. In China, the endoscopic prevalence of BE is lower, but the average age of diagnosis is younger; a high proportion of H. pylori infection is found in patients with BE, and about half of the patients have no typical symptoms of GERD; the tongue-type BE and the LSBE are apt to SIM.

Abdel-Latif and colleagues recently suggested that esophageal adenocarcinoma patients with GERD might be resistant to multimodality treatment. In this study, we investigated potential differences in clinical outcomes in esophageal adenocarcinoma patients based on the presence of identifiable Barrett's mucosa and/or history of symptomatic GERD. METHODS: Eighty-four patients with resectable esophageal adenocarcinoma, who completed the planned preoperative chemoradiation and underwent a potentially curative esophageal resection were retrospectively evaluated. Postoperative survival was compared between patients with or without underlying Barrett's esophagus and history of symptomatic GERD. Patients with pathologic complete response (path CR) and those with partial or no response (path PR) were compared to determine if presence of Barrett's esophagus and history of symptomatic GERD influence the path CR rates. RESULTS: We found significantly lower postoperative survival in patients with Barrett's associated adenocarcinoma (vs adenocarcinoma arising de novo, p = 0.031) and patients with symptomatic GERD (vs patients without symptomatic GERD, p = 0.019). Furthermore, the subset of patients with path PR (vs path CR) after chemoradiation have a significantly higher proportion of patients with Barrett's esophagus (HR = 4.38, confidence interval [CI] = 1.39 to 13.83, p = 0.012) and patients with GERD (HR = 2.71, CI = 1.13 to 6.50, p = 0.026). CONCLUSIONS: Patients with esophageal adenocarcinoma may have differences in response to preoperative chemoradiation based on the presence of Barrett's esophagus and history of symptomatic GERD.

OBJECTIVES: The primary objective of this review was to assess the impact of reducing the costs of providing or using smoking cessation treatment through healthcare financing interventions on abstinence from smoking. The secondary objectives were to examine the effects of different levels of financial support on the use and/or prescription of smoking cessation treatment and on the number of smokers making a quit attempt. SEARCH METHODS: We searched the Cochrane Tobacco Addiction Group Specialized Register in April 2012. SELECTION CRITERIA: We considered randomised controlled trials (RCTs), controlled trials and interrupted time series studies involving financial benefit interventions to smokers or their healthcare providers or both. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed the quality of the included studies. Risk ratios (RR) were calculated for individual studies on an intention-to-treat basis and meta-analysis was performed using a random-effects model. We included economic evaluations when a study presented the costs and effects of two or more alternatives. MAIN RESULTS: We found eleven trials involving financial interventions directed at smokers and healthcare providers.Full financial interventions directed at smokers had a statistically significant favourable effect on abstinence at six months or greater when compared to no intervention (RR 2.45, 95% CI 1.17 to 5.12, I(2) = 59%, 4 studies). There was also a significant effect of full financial interventions when compared to no interventions on the number of participants making a quit attempt (RR 1.11, 95% CI 1.04 to 1.32, I(2) = 15%) and use of smoking cessation treatment (NRT: RR 1.83, 95% CI 1.55 to 2.15, I(2) = 43%; bupropion: RR 3.22, 95% CI 1.41 to 7.34, I(2) = 71%; behavioural therapy: RR 1.77, 95% CI 1.19 to 2.65). There was no evidence of an effect on smoking cessation when we pooled two trials of financial incentives directed at healthcare providers (RR 1.16, CI 0.98 to 1.37, I(2) = 0%). Comparisons of full coverage with partial coverage, partial coverage with no coverage, and partial coverage with another partial coverage intervention did not detect significant effects. Comparison of full coverage with partial or no coverage resulted in costs per additional quitter ranging from $119 to $6450. AUTHORS' CONCLUSIONS: Full financial interventions directed at smokers when compared to no financial interventions increase the proportion of smokers who attempt to quit, use smoking cessation treatments, and succeed in quitting. The absolute differences are small but the costs per additional quitter are low to moderate. We did not detect an effect on smoking cessation from financial incentives directed at healthcare providers. The methodological qualities of the included studies need to be taken into consideration when interpreting the results.

DESIGN: Cross-sectional study within the population-based Swedish Twin Registry. SETTING AND PARTICIPANTS: A total of 31 213 male and female twins 42-64 years old. MEASUREMENTS: Age-adjusted prevalence odds ratios (POR) and 95% confidence intervals (CIs) described the association between gender and tobacco use, while Kaplan-Meier survival methods produced cumulative incidence curves of age at onset of tobacco use. Life-time tobacco use histories were constructed using ages at onset of tobacco use and current tobacco use status. FINDINGS: Although more males reported ever smoking (64.4%) than females (61.7%), more males were former smokers (POR: 1.33, 95% CI: 1.27-1.39). Males were far more likely to use snus than females (POR: 18.0, 95% CI: 16.17-20.04). Age at onset of cigarette smoking occurred almost entirely before age 25, while the age at onset of snus use among males occurred over a longer time period. Most men began using cigarettes first, nearly one-third of whom switched to using cigarettes and snus in combination. While 30.6% of these combined users quit tobacco completely, only 7.4% quit snus and currently use cigarettes, while 47.7% quit cigarettes and currently use snus. CONCLUSIONS: Current cigarette smoking is more prevalent among Swedish women than men, while snus use is more prevalent among men. Among men who reported using both cigarettes and snus during their life-time, it was more common to quit cigarettes and currently use snus than to quit snus and currently use cigarettes. Once snus use was initiated, more men continued using snus rather than quit tobacco completely.

Pub Date Free Form 1991/ Volume 102 Issue Start Page 35 Other Pages 73 Notes Place of Publication ISSN/ISBN 0048-9697 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Water samples were collected from 384 waterworks that supply 70.9% of the Norwegian population. The samples were collected after water treatment and were analysed for 30 constituents. Although most constituents show wide concentration ranges, Norwegian drinking water is generally soft. The median values obtained are: 0.88 mg Si l-1, 0.06 mg Al l-1, 47 Î¼g Fe l-1, 0.69 mg Mg l-1, 2.9 mg Ca l-1, 3.8 mg Na l-1, 6 Î¼g Mn l-1, 12 Î¼g Cu l-1, 14 Î¼g Zn l-1, 9 Î¼g Ba l-1, 15 Î¼g Sr l-1, 0.14 mg K l-1, 58 Î¼g F- l-1, 6.4 mg Cl- l-1, 11 Î¼g Br- l-1, 0.46 mg NO3- l-1, 5.3 mg SO42- l-1, 2.4 mg TOC l-1, 6.8 (pH), 50 Î¼S cm-1 (conductivity) and 11 mg Pt l-1 (colour). Titanium, Pb, Ni, Co, V, Mo, Cd, Be and Li were seldom or never quantified, due to insufficient sensitivity of the ICP (inductively coupled plasma) method. Norwegian quality criteria, which exist for 17 of the constituents examined, are generally fulfilled, indicating that the chemical quality of drinking water, by and large, is good in Norway. For Fe, Ca, Mn, Cu, pH, TOC and colour, however, the norms for good drinking water are exceeded in more than 9% of the samples, reflecting two of the major problems associated with Norwegian drinking water supplies: (i) many water sources contain high concentrations of humic substances; (ii) in large parts of the country, the waters are soft and acidic, and therefore corrosive towards pipes, plumbing and other installations. Most constituents show marked regional distribution patterns, which are discussed in the light of different mechanisms contributing to the chemical composition of drinking water, namely: chemical weathering of mineral matter; atmospheric supply of salt particles from the sea; anthropogenic pollution (including acid precipitation); corrosion of water pipes and plumbing; water treatment; decomposition of organic matter; and hydrological differences.

HYPOTHESIS: Coronary artery disease only progresses slowly with comprehensive risk factor intervention. METHODS: A total of 104 of 201 patients (51.7%) of the Swiss Interventional Study on Silent Ischemia Type II (SWISSI II) with baseline and follow-up coronary angiography were included. All patients received comprehensive cardiovascular risk factor intervention according to study protocol. Logistic regression was used to evaluate associations between baseline cardiovascular risk factors and CAD progression. RESULTS: The mean duration of follow-up was 10.3+/-2.4 years. At baseline, 77.9% of patients were smokers, 45.2% had hypertension, 73.1% had dyslipidemia, 7.7% had diabetes, and 48.1% had a family history of CAD. At last follow-up, only 27 patients of the initial 81 smokers still smoked, only 2.1% of the patients had uncontrolled hypertension, 10.6% of the patients had uncontrolled dyslipidemia, and 2.1% of the patients had uncontrolled diabetes. Coronary artery disease progression was found in up to 81 (77.9%) patients. Baseline diabetes and younger age were associated with increased odds of CAD progression. The time interval between baseline and follow-up angiography was also associated with CAD progression. CONCLUSION: Coronary artery disease progression was highly prevalent in these patients despite comprehensive risk factor intervention. Further research is needed to optimize treatment of known risk factors and to identify other unknown and potentially modifiable risk factors.

METHODS: We performed a systematic literature search to identify relevant studies, scored their quality, used fixed and random-effect models to estimate summary relative risks (SRR), evaluated heterogeneity and publication bias. RESULTS: We retrieved information from 28 published reports. Considering only highquality studies, waterpipe smoking was associated with increased risk of head and neck cancer (SRR 2.97; 95 % CI 2.26-3.90), esophageal cancer (1.84; 1.42-2.38) and lung cancer (2.22; 1.24-3.97), with no evidence of heterogeneity or publication bias. Increased risk was also observed for stomach and bladder cancer but based mainly on poor-quality studies. For colorectum, liver and for all sites combined risk estimates were elevated, but there were insufficient reports to perform a meta-analysis. CONCLUSIONS: Contrary to the perception of the relative safety of waterpipe smoking, this meta-analysis provides quantitative estimates of its association with cancers of the head and neck, esophagus and lung. The scarcity and limited quality of available reports point out the need for larger carefully designed studies in well-defined populations.

Previous studies have suggested a synergistic relationship between CO(2) laser irradiation and fluoride treatment on increased resistance to acid dissolution. In this study a near-UV laser operating with lambda = 355-nm laser pulses of 3-5 nanoseconds duration was used to modify the surface morphology of dental enamel to increase the bond strength to restorative materials and increase the uptake of topical fluoride to render the surface more resistant to acid dissolution. We hypothesize that the short UV laser pulses are primarily absorbed by protein and lipid localized between the enamel prisms resulting in removal of intact mineral effectively etching the surface without thermal modification of the mineral phase. Such modification is likely to increase the permeability of the enamel surface and the subsequent absorption of fluoride. In addition, there is an increase in surface roughness without the formation of a layer of loosely adherent, thermally modified enamel that increases the bond strength to composite restorative materials. STUDY DESIGN/MATERIALS AND METHODS: The surfaces of blocks of bovine enamel, 5 x 5 mm(2), were uniformly irradiated by 355-nm laser pulses and subsequently bonded to composite. The shear bond test was used to assess the bond strength of non-irradiated blocks (negative control), acid etched blocks (positive control), and laser irradiated blocks. The resistance to acid dissolution was evaluated using controlled surface dissolution experiments on irradiated samples, irradiated samples exposed to topical fluoride, and non-irradiated control samples with and without fluoride. RESULTS: The laser surface treatments significantly increased the shear-bond strength of enamel to composite, to a level exceeding 20 MPa which was significantly more than the non-irradiated control samples and significantly less than the acid etch. Laser irradiation alone and topical fluoride application alone did not significantly increase the resistance to acid dissolution. The laser treatment followed by topical application of fluoride significantly increased the resistance to acid dissolution to a level of over 50% versus the control samples. CONCLUSIONS: We present a novel method for increasing bond strength to restorative materials and enhancing fluoride delivery to enamel surfaces and shed some light on the underlying mechanisms of caries inhibition via laser treatment and topical application of fluoride.

METHODS: From Jul 2011 to April 2013, a total of 256 women with hypoestrogenism in the First Affiliated Hospital of Shanxi Medical University were enrolled in this retrospective study, which were divided into four groups:133 women in ppausal group, 25 women in premature ovarian failure (POF) group, 67 women in menopausal transition group and 31 women in premature ovarian failure transition group.General statue, CVD risk factors and BMD were compared among four groups.General statue include menopausal period, menopausal symptoms (Kupperman Index), CVD risk factors include body mass index, blood pressure, waist circumference, waist-hip ratio, blood lipids and glucose, BMD include left hip, lumbar spine bone mineral density and T or Z value. RESULTS: (1) The median menopausal period were 3.4 years in postmenopausal group and 3.6 years in premature ovarian failure group, which did not show no statistical difference (P > 0.05).Kupperman Index in four groups were 12 in postmenopausal group, 9 in POF group, 9 in menopausal transition group and 8 in premature ovarian failure transition group, which reached statistical difference (P 0.05); the systolic blood pressure in four groups were 120, 110, 110, 110 mm Hg (1 mm Hg = 0.133 kPa), their differences were statistically significance (P 0.05); the systolic blood pressure in four groups were 120, 110, 110, 110 mm Hg (1 mm Hg = 0.133 kPa), their differences were statistically significance (P 0.05).(3) The abnormal rate of lower bone mass in lumbar spine were 57% (46/81) postmenopausal group, 8/15 in POF group, 32% (9/28) in menopausal transition group, 12/19 in premature ovarian failure transition group, and osteoporosis was 9% (7/81), 3/15, 1% (3/28) and 0 respectively , their differences were statistically different (P Descriptors Links Book Title Database Publisher Data Source Authors Zhao,F., Guo,X.T., Cheng,Y., Yang,Z.F., Liu,H.P.
