1Extrahepatic complications to cirrhosis and portal hypertension: Haemodynamic and homeostatic aspects显示文摘In addition to complications relating to the liver, patients with cirrhosis and portal hypertension develop extrahepatic functional disturbances of multiple organ systems. This can be considered a multiple organ failure that involves the heart, lungs, kidneys, the immune systems, and other organ systems. Progressive fibrosis of the liver and subsequent metabolic impairment leads to a systemic and splanchnic arteriolar vasodilatation. This affects both the haemodynamic and functional homeostasis of many organs and largely determines the course of the disease. With the progression of the disease, the circulation becomes hyperdynamic with cardiac, pulmonary as well as renal consequences for dysfunction and reduced survival. Infections and a changed cardiac function known as cirrhotic cardiomyopathy may be involved in further aggravation of other complications such as renal failure precipitatingthe hepatorenal syndrome.Patients with end-stage liver disease and related complications as for example the hepatopulmonary syndrome can only radically be treated by liver transplantation.As a bridge to this treatment,knowledge on the mechanisms of the pathophysiology of complications is essential for the choice of vasoactive drugs,antibiotics,drugs with specific effects on fibrogenesis and inflammation,and drugs that target specific receptors.S?ren M?ller Jens H Henriksen Flemming Bendtsen 2014World Journal of Gastroenterology2014,20,42:14
2Pharmacological approach to acute pancreatitis显示文摘The aim of the present review is to summarize the current knowledge regarding pharmacological prevention and treatment of acute pancreatitis (AP) based on experimental animal models and clinical trials. Somatostatin (SS) and octreotide inhibit the exocrine production of pancreatic enzymes and may be useful as prophylaxis against Post Endoscopic retrograde cholangiopancreatography Pancreatitis (PEP). The protease inhibitor Gabexate mesilate (GM) is used routinely as treatment to AP in some countries, but randomized clinical trials and a meta-analysis do not support this practice. Nitroglycerin (NGL) is a nitrogen oxide (NO) donor, which relaxes the sphincter of Oddi. Studies show conflicting results when applied prior to ERCP and a large multicenter randomized study is warranted. Steroids administered as prophylaxis against PEP has been validated without effect in several randomized trials. The non-steroidal anti-inflammatory drugs (NSAID) indomethacin and diclofenac have in randomized studies showed potential as prophylaxis against PEP. Interleukin 10 (IL-10) is a cytokine with anti-inflammatory properties but two trials testing IL-10 as prophylaxis to PEP have returned conflicting results. Antibodies against tumor necrosis factor-alpha (TNF-α) have a potential as rescue therapy but no clinical trials are currently being conducted. The antibiotics beta- lactams and quinolones reduce mortality when necrosis is present in pancreas and may also reduce incidence of infected necrosis. Evidence based pharmacological treatment of AP is limited and studies on the effect of potent anti-inflammatory drugs are warranted.Ulrich Christian Bang Synne Semb Camilla Nφjgaard Flemming Bendtsen 2008World Journal of Gastroenterology2008,14,19:10
3Systematic review of the prevalence and development of osteoporosis or low bone mineral density and its risk factors in patients with inflammatory bowel disease显示文摘BACKGROUND The inflammatory bowel diseases(IBD),Crohn’s disease(CD)and ulcerative colitis(UC)are chronic,immune-mediated disorders of the digestive tract.IBD is considered to be a risk factor for developing osteoporosis;however current literature on this matter is inconsistent.AIM To assess prevalence and development of osteoporosis and low bone mineral density(BMD),and its risk factors,in IBD patients.METHODS Systematic review of population-based studies.Studies were identified by electronic(January 2018)and manual searches(May 2018).Databases searched included EMBASE and PubMed and abstracts from 2014-2018 presented at the United European Gastroenterology Week,the European Crohn’s and Colitis Organisation congress,and Digestive Disease Week were screened.Studies were eligible for inclusion if they investigated either the prevalence of osteoporosis or osteopenia and/or risk factors for osteoporosis or low BMD in IBD patients.Studies on children under the age of 18 were excluded.Only population-based studies were included.All risk factors for osteoporosis and low BMD investigated in any included article were considered.Study quality and the possibility of bias were analysed using the Newcastle-Ottawa scale.RESULTS Twelve studies including 3661 IBD patients and 12789 healthy controls were included.Prevalence of osteoporosis varied between 4%-9%in studies including both CD and UC patients;2%-9% in studies including UC patients, and 7%-15% instudies including CD patients. Among healthy controls, prevalence ofosteoporosis was 3% and 10% in two studies. CD diagnosis, lower body massindex (BMI), and lower body weight were risk factors associated withosteoporosis or low BMD. Findings regarding gender showed inconsistent results.CD patients had an increased risk for osteoporosis or low BMD over time, whileUC patients did not. Increased age was associated with decreased BMD, and therewas a positive association between weight and BMI and BMD over time. Greatheterogeneity was found in the included studies in terms of study methodologies,definitions and the assessment of osteoporosis, and only a small number ofpopulation-based studies was available.CONCLUSIONThis systematic review found a possible increase of prevalence of osteoporosis inCD cohorts when compared to UC and cohorts including both disease types.Lower weight and lower BMI were predictors of osteoporosis or low BMD in IBDpatients. The results varied considerably between studies.Sofia Kärnsund Bobby Lo Flemming Bendtsen Jakob Holm Johan Burisch 2020World Journal of Gastroenterology2020,26,35:8
4脑海绵状血管畸形临床诊疗指南概要:血管瘤联盟科学咨询委员会临床专家组基于系统文献评价的共识推荐显示文摘背景尽管脑海绵状血管畸形(cerebral cavernous malformation, CCM)的相关研究文献已相当丰富,但在诊断和治疗策略方面仍存在着争议。目的制订CCM诊疗指南。方法作为代表CCM患者和研究的患者支持团体,血管瘤联盟(www.angioma.org)召集了一个包括CCM临床专家在内的多学科写作组来帮助总结现有的CCM临床诊疗相关文献,重点关注5个主题:(1)流行病学和自然病程;(2)遗传检测和咨询;(3)诊断标准和影像学标准;(4)神经外科注意事项;(5)神经内科注意事项。写作组根据预定方案进行了文献回顾和证据评价,最终制定推荐意见,并且确立了共识、争议和知识空白。结果根据方法学标准从1983年1月1日至2014年9月31日期间公开发表的1 270篇文献中筛选出98篇,并确定了另外38篇近期或相关的文献。各主题作者利用这些文献总结了现有知识并形成了23项共识诊疗推荐,同时根据美国心脏协会/美国卒中协会标准进行了推荐强度(效应量)和证据水平(确定性估计)评级。其中,尚无A级证据(因为缺乏随机对照试验),B级证据11项(48%),C级证据12项(52%);Ⅰ级推荐8项(35%),Ⅱ级推荐10项(43%),Ⅲ级推荐5项(22%)。结论现有证据支持对CCM诊疗的推荐,但这些证据的级别和推荐强度普遍较低,因此需要进一步研究来帮助进行更好的临床实践并更新这些推荐。完整的推荐文档包括引用文献的纳入标准、关于各项推荐更详尽的评判标准以及各种争议和知识空白的总结,同样通过了同行评议并可在线获取(www.angioma.org/CCMGuidelines)。Amy Akers Rustam Al-Shahi Salman Issam A.

5Effect of Prometheus liver assist system on systemic hemodynamics in patients with cirrhosis: A randomized controlled study显示文摘AIM: To evaluate treatment safety and hemodynamic changes during a single 6-h treatment with the Prometheus? liver assist system in a randomized, controlled study. METHODS: Twenty-four patients were randomized to either the study group or to one of two control groups: Fractionated Plasma Separation Adsorption and Dialysis, Prometheus? system (Study group; n = 8); Molecular Adsorbent Recirculation System (MARS)? (Control group 1, n = 8); or hemodialysis (Control group 2; n = 8). All patients included in the study had decompensated cirrhosis at the time of the inclusion into the study. Circulatory changes were monitored with a Swan-Ganz catheter and bilirubin and creatinine were monitored as measures of protein-bound and water-soluble toxins. RESULTS: Systemic hemodynamics did not differ between treatment and control groups apart from an increase in arterial pressure in the MARS group (P = 0.008). No adverse effects were observed in any of the groups. Creatinine levels significantly decreased in the MARS group (P = 0.03) and hemodialysis group (P = 0.04). Platelet count deceased in the Prometheus group (P = 0.04).CONCLUSION: Extra-corporal liver support with Prometheus is proven to be safe in patients with end- stage liver disease but does not exert the beneficial effects on arterial pressure as seen in the MARS group.Thomas Dethloff Flemming Tofteng Hans-Jorgen Frederiksen Michael Hojskov Bent Adel Hansen Fin Stolze Larsen 2008World Journal of Gastroenterology2008,14,13:4

7大型太阳能供热显示文摘太阳能是我们目前能够利用的最为明显的CO2零排放的热源,并且它具有分布广泛的特点。然而,利用太阳能供热存在的问题是前期建设资本投入大,而且在日照充足时会提供过量的热能。即便存在这样的问题,目前包括丹麦在内的北欧各国,对于太阳能供热的市场需求仍然呈日益上升的趋势。Flemming Ulbjerg 李晨 张明明 2009区域供热2009,,2:3
8Persistent severe hypomagnesemia caused by proton pump inhibitor resolved after laparoscopic fundoplication显示文摘Magnesium deficiency can cause a variety of symptoms, including potentially life-threatening complications such as seizures, cardiac arrhythmias and secondary electrolyte disturbances. Hypomagnesemia can be a serious adverse effect to proton pump inhibitor(PPI) therapy, which is worrying due to the widespread use of PPIs. Current evidence suggest that the mechanism of PPI induced hypomagnesemia is impaired intestinal magnesium absorption. In this report, we present the case of a long-term PPI user with persistent hypomagnesemia with severe symptoms at presentation. He was unable to stop PPI treatment because of severe reflux symptoms, and was dependent on weekly intravenous magnesium infusions, until his magnesium levels finally normalized without the need for supplementation after a successful laparoscopic fundoplication.Synne Semb Frederik Helgstrand Flemming Hjorne Peter Bytzer 2017World Journal of Gastroenterology2017,23,37:2
9WJD 5^(th) Anniversary Special Issues(2): Type 2 diabetes Effects of exercise training on mitochondrial function in patients with type 2 diabetes显示文摘Type 2 diabetes is characterized by a decreased ability of insulin to facilitate glucose uptake into insulin sensitive tissue,i.e.,skeletal muscle.The mechanism behind this is at the moment unresolved.It has been suggested that increased amount of lipids inside the skeletal muscle(intramuscular triglyceride,diacylglycerol and ceramides)will impair insulin action in skeletal muscle,but data are not consistent in the human literature.It has also been hypothesized that the impaired insulin sensitivity is due to a dysfunction in the mitochondria resulting in an impaired ability to oxidize lipids,but the majority of the literature is not supporting this hypothesis.Recently it has been suggested that the production of reactive oxygen species play an essential role in skeletal muscle insulin sensitivity.It is well accepted that physical activity(endurance,strength and high intensity training)improves insulin sensitivity in healthy humans and in patients with type 2 diabetes.Whether patients with type 2 diabetes have the same beneficial effects(same improvement)as control subjects,when it comes to regular physical activity in regard to mitochondrial function,is not established in the literature.This review will focus only on the effect of physical activity on skeletal muscle(mitochondrial function)in patients with type 2 diabetes.Steen Larsen Stinna Skaaby J rn W Helge Flemming Dela 2014World Journal of Diabetes2014,5,4:2

12Safety and efficacy of Profermin~to induce remission in ulcerative colitis显示文摘AIM:To test the efficacy and safety of Profermin in inducing remission in patients with active ulcerative colitis(UC).METHODS:The study included 39 patients with mild to moderate UC defined as a Simple Clinical Colitis Activity Index(SCCAI)>4 and<12(median:7.5),who were treated open-label with Profermintwice daily for 24 wk.Daily SCCAI was reported observer blinded via the Internet.RESULTS:In an intention to treat(ITT)analysis,the mean reduction in SCCAI score was 56.5%.Of the 39 patients,24(62%)reached the primary endpoint,which was proportion of patients with≥50%reduction in SCCAI.Our secondary endpoint,the proportion of patients in remission defined as SCCAI≤2.5,was in ITT analysis reached in 18 of the 39 patients(46%).In a repeated-measure regression analysis,the estimated mean reduction in score was 5.0 points(95%CI:4.1-5.9,P<0.001)and the estimated mean time taken to obtain half the reduction in score was 28 d(95%CI:26-30).There were no serious adverse events(AEs)or withdrawals due to AEs.Profermin was generally well tolerated.CONCLUSION:Profermin is safe and may be effective in inducing remission of active UC.Aleksander Krag Hans Israelsen Bjrn von Ryberg Klaus K Andersen Flemming Bendtsen 2012World Journal of Gastroenterology2012,18,15:2
13六氯化苯对汤氏纺锤水蚤毒性影响的比较研究显示文摘本文通过1987年6月在丹麦国家环保局海洋污染实验室进行的六氯化苯(γ-HCH)对桡足类汤氏纺锤水蚤(Acartia tonsa)的急性、亚急性和生命周期试验,评价了六氯化苯对汤氏纺锤水蚤的毒性。试验结果表明,γ-HCH对汤氏纺锤水蚤的96h LC_(50)为17μg/L。当,γ-HCH浓度为3μg/L时,产卵量明显受到影响。在生命周期试验中,当γ-HCH浓度为10μg/L时,从无节幼体Ⅵ期到成体,汤氏纺锤水蚤的生长会受到明显影响,而对雌性成体的半数影响浓度(EC_(50))为0.8μg/L。通过对试验方法和结果的比较分析文中认为,汤氏纺锤水蚤的生命周期试验,敏感性高、操作简便、费用相对较低,将会是化学物质危害性评价中一个很有用的方法。陈民山 Flemming Mhlenberg 1991海洋与湖沼1991,22,3:2
14Axial force measurement for esophageal function testing显示文摘The esophagus serves to transport food and fluid from the pharynx to the stomach. Manometry has been the 'golden standard' for the diagnosis of esophageal motility diseases for many decades. Hence, esophageal function is normally evaluated by means of manometry even though it reflects the squeeze force (force in radial direction) whereas the bolus moves along the length of esophagus in a distal direction. Force measurements in the longitudinal (axial) direction provide a more direct measure of esophageal transport function. The technique used to record axial force has developed from external force transducers over in-vivo strain gauges of various sizes to electrical impedance based measurements. The amplitude and duration of the axial force has been shown to be as reliable as manometry. Normal, as well as abnormal, manometric recordings occur with normal bolus transit, which have been documented using imaging modalities such as radiography and scintigraphy. This inconsistency using manometry has also been documented by axial force recordings. This underlines the lack of information when diagnostics are based on manometry alone. Increasing the volume of a bag mounted on a probe with combined axial force and manometry recordings showed that axial force amplitude increased by 130% in contrast to an increase of 30% using manometry. Using axial force in combination with manometry provides a more complete picture of esophageal motility, and the current paper outlines the advantages of using this method.Flemming H Gravesen Peter Funch-Jensen Hans Gregersen Asbjφrn Mohr Drewes 2009World Journal of Gastroenterology2009,15,2:2
