| 1 | Bone mineral density and disorders of mineral metabolism in chronic liver disease显示文摘AIM:To estimate the prevalence and identify the risk factors for metabolic bone disease in patients with cirrhosis.METHODS:The study was performed on 72 Indian patients with cirrhosis(63 male, 9 female;aged < 50 years).Etiology of cirrhosis was alcoholism(n = 37), hepatitis B(n = 25) and hepatitis C(n = 10).Twenty-three patients belonged to Child class A, while 39 were in class B and 10 in class C.Secondary causes for metabolic bone disease and osteoporosis were ruled out.Sunlight exposure, physical activity and dietary constituents were calculated.Complete metabolic profiles were derived, and bone mineral density(BMD) was measured using dual energy X ray absorptiometry.Low BMD was defined as a Z score below-2.RESULTS:Low BMD was found in 68% of patients.Lumbar spine was the most frequently and severely affected site.Risk factors for low BMD included low physical activity, decreased sunlight exposure, and low lean body mass.Calcium intake was adequate, with unfavorable calcium:protein ratio and calcium:phosphorus ratio.Vitamin D deficiency was highly prevalent(92%).There was a high incidence of hypogonadism(41%).Serum estradiol level was elevated significantly in patients with normal BMD.Insulin-like growth factor(IGF) 1 and IGF binding protein 3 levels were below the age-related normal range in both groups.IGF-1 was signiflcantly lower in patients with low BMD.Serum osteocalcin level was low(68%) and urinary deoxypyridinoline to creatinine ratio was high(79%), which demonstrated low bone formation with high resorption.CONCLUSION:Patients with cirrhosis have low BMD.Contributory factors are reduced physical activity, low lean body mass, vitamin D def iciency and hypogonadism and low IGF-1 level. | Joe George Hosahithlu K Ganesh Shrikrishna Acharya Tushar R Bandgar Vyankatesh Shivane Anjana Karvat Shobna J Bhatia Samir Shah Padmavathy S Menon Nalini Shah | 2009 | World Journal of Gastroenterology2009，15，28： | 15 |
| 2 | 发展中国家的可再生能源:沼气的机遇和挑战显示文摘能源对于现代社会至关重要,是社会经济发展最重要的指标之一。尽管科技不断发展,但仍然有约30亿人(主要集中在发展中国家的农村地区),继续通过在传统的炉灶中燃烧生物质资源(如柴薪、秸秆、动物粪便)的方式来满足烹饪的能源需求。这种方式对环境、社会、经济、公众健康都带来极大负面影响。这些地区要实现可持续性发展,开发干净清洁、价格低廉的可再生能源就势在必行。把现有的生物质资源(动物粪便、秸秆、餐厨垃圾、绿色废弃物)提炼成更加清洁高效的能源载体(例如厌氧发酵产生的沼气),不仅具有提供清洁、可靠能源的独特潜力,同时又能保护当地和全球的环境。尽管沼气对发展中国家来说意义重大,但其面临着成本高、设备安装和维护专业知识缺乏等问题,因而在地理位置分散的社区难以广泛推广应用。因此,政府和非政府层面的通力协作就显得至关重要,从而促进沼气技术的更新改造和传播,开发尚未被开发的潜力。文章旨在通过分析沼气技术的现状、挑战和潜力,明确它在发展中国家未来的研究方向和发展传播路径。 | K C Surendra Devin Takara rew G Hashimoto Samir Kumar Khanal 李谦 | 2015 | 中国沼气2015，33，1： | 3 |
| 3 | End-stage renal disease is associated with increased post endoscopic retrograde cholangiopancreatography adverse events in hospitalized patients显示文摘AIM To determine if end-stage renal disease (ESRD) is a risk factor for post endoscopic retrograde cholangio-pancreatography (ERCP) adverse events (AEs). METHODS We performed a retrospective cohort study using the Nationwide Inpatient Sample (NIS) 2011-2013. We identified adult patients who underwent ERCP using the International Classification of Diseases 9^(th) Revision (ICD-9-CM). Included patients were divided into three groups: ESRD, chronic kidney disease (CKD), and control. The primary outcome was post-ERCP AEs including pancreatitis, bleeding, and perforation determined based on specific ICD-9-CM codes. Secondary outcomes were length of hospital stay, in-hospital mortality, and admission cost. AEs and mortality were compared using multivariate logistic regression analysis.RESULTS There were 492175 discharges that underwent ERCP during the 3 years. The ESRD and CKD groups contained 7347 and 39403 hospitalizations respectively, whereas the control group had 445424 hospitalizations. Post-ERCP pancreatitis (PEP) was significantly higher in the ESRD group (8.3%) compared to the control group (4.6%) with adjusted odd ratio (aOR) = 1.7 (95% CI: 1.4-2.1, ~aP < 0.001). ESRD was associated with significantly higher ERCP-related bleeding (5.1%) compared to the control group 1.5% (aOR = 1.86, 95%CI: 1.4-2.4, ~aP < 0.001). ESRD had increased hospital mortality 7.1% vs 1.15% in the control OR = 6.6 (95%CI: 5.3-8.2, ~aP < 0.001), longer hospital stay with adjusted mean difference (aMD) = 5.9 d (95% CI: 5.0-6.7 d, ~aP < 0.001) and higher hospitalization charges aMD = $+82064 (95%CI: $68221-$95906, ~aP < 0.001). CONCLUSION ESRD is a risk factor for post-ERCP AEs and is associated with higher hospital mortality. Careful selection and close monitoring is warranted to improve outcomes. | Tarek Sawas Fateh Bazerbachi Samir Haffar Won K Cho Michael J Levy John A Martin Bret T Petersen Mark D Topazian Vinay Chandrasekhara Barham K Abu Dayyeh | 2018 | World Journal of Gastroenterology2018，24，41： | 2 |
