1CONSORT 2010说明与详述:报告平行对照随机临床试验指南的更新显示文摘大量证据显示随机对照临床试验(randomised controlled trial,RCT)的报告质量不理想。报告不透明,则读者既不能评判试验结果是否真实可靠,也不能从中提取可用于系统综述的信息。最近的方法学分析表明,报告不充分和设计不合理与对治疗效果产生评价偏倚有关。这种系统误差对RCT损害严重,而RCT正是以其能减少或避免偏倚而被视为评价干预措施的金标准。为了提高RCT的报告质量,一个由专家和编辑组成的工作组制定了临床试验报告的统一标准(Consolidated Standards of Reporting Trials,CONSORT)声明。CONSORT声明于1996年首次发表,并于2001年更新。声明由对照检查清单和流程图组成,供作者在报告RCT时使用。许多核心医学期刊和主要国际性编辑组织都已认可CONSORT声明。该声明促进了对RCT的严格评价和解释。2001年,在对CONSORT进行修订时,人们就已经清楚地认识到,解释和说明制定CONSORT声明的原理,有助于研究人员等撰写或评价临床试验报告。一篇CONSORT说明与详述文章于2001年同2001版CONSORT声明一起发表。2007年1月的专家会议之后,对CONSORT声明作了进一步修订并已发表,即'CONSORT2010声明'。这次更新对原版对照检查清单作了文字上的修改,使其更为明晰,并收入了与一些新近才认识到的主题相关的建议,如选择性报告结局产生的偏倚。说明与详述文件旨在加强人们对CONSORT声明的理解、应用和传播,这次也作了大量修订,对每一项新增或更新的清单条目的含义和增改理由进行了解释,提供了优秀的报告实例,还尽可能地提供了相关的经验性研究的参考文献。文中收入了若干流程图实例。'CONSORT2010声明'、其说明与详述文件,以及相关网站(www.consort-statement.org),对于改进随机临床试验报告必将有所裨益。David Moher Sally Hopewell Kenneth F Schulz Victor Montori Peter C Gφtzsche P J Devereaux Diana Elbourne Matthias Egger Douglas G Altman 周庆辉 卞兆祥 刘建平 2010中西医结合学报2010,8,8:318
2Association of 25-hydroxy-vitamin D levels with semen and hormonal parameters显示文摘维生素 D 层次包括繁殖混乱被连接了到各种各样的健康结果。这研究的目的是探索在浆液维生素 D 水平(25-hydroxy-vitamin D,或 25OHD ) 和精液和神经质的参数之间的协会。这是包括了从一般人口为精子发生的学习招募的 170 个健康的人的代表性的研究。完成的将军和繁殖健康问询表,和捐赠的血和精液取样的人。主要措施是神经质的(全部、免费的睾丸激素,性荷尔蒙绑定血球素, estradiol ,刺激滤泡的荷尔蒙和 luteinizing 荷尔蒙)并且精液参数,调整( n=147 )好久,身体团索引( BMI ),季节,白酒吸入并且吸烟,在与维生素 D 层次的范畴的关系,决定了 priori 。学习人口的吝啬的年龄是 29.0 ± 8.5 年和吝啬的 BMI 是 24.3 ± 3.2   kg m −2 。吝啬的 25OHD 是 34.1 ± 15.06   ng ml −1 。BMI 与 25OHD 显示出一个否定协会。精子集中,进步活动性,精子形态学,和全部的日益增多地能动的精子数的精子在有 ‘ 的人是更低的; 25OHD ≥ 50   ng ml −1' 什么时候与有 ‘ 的人相比; 20 ng ml −1≤25OHD<50 ng ml −1' 。全部的精子计数和全部的进步能动精子计数在有 ‘ 的人是更低的; 25OHD < 20   ng ml −1' 什么时候与有 ‘ 的人相比; 20 ng ml −1≤25OHD<50 ng ml −1' 。各种各样的神经质的参数的调整工具没在 25OHD 的不同范畴显示出统计差别。在结论,在高度和底层的浆液维生素 D 层次能否定地与精液参数被联系。Ahmad O Hammoud A Wayne Meikle C Matthew Peterson Joseph Stanford Mark Gibson Douglas T Carrell 2012Asian Journal of Andrology2012,14,6:19
3加强流行病学中观察性研究报告质量(STROBE)声明:观察性研究报告规范显示文摘很多生物医学研究都是观察性的。但对这类研究的报告却通常不完整,从而限制了对其优缺点及普适性的评价。“加强流行病学中观察性研究报告质量(STROBE)”工作组针对一篇完整明确的观察性研究报告应包括的内容提供了一套建议。建议涵盖了流行病学研究的三种主要设计类型:队列设计、病例对照设计和横断面设计。2004年9月,我们召开了为期2天的研讨会,与会的方法学专家、研究人员和期刊编辑共同起草了一份观察性研究报告应纳入的条目清单草案。此后,又通过协调小组数次会议及与有关人员电子邮件讨论等对该草案进行了修改,纳入了经验性证据和方法学方面的意见。通过研讨会及之后反复的咨询和修订,我们制定出了一个包含22个条目的清单(STROBE声明),分为论文的题目、摘要、引言、方法、结果和讨论等部分。其中18个条目适用于所有三种主要的观察性研究设计,其余4个条目则专门用于队列、病例一对照或横断面设计。详细的解释和示范文件已另行发表,在《公共科学图书馆一医学》(PLoS Medicine)、《内科学年报》(Annalsof Internal Medicine)和《流行病学》(Epidemiology)的网站可以免费获得。我们希望STROBE声明能有助于改善观察性研究报告的质量。Erikvon Elm Douglas G Altman Matthias Egger Stuart J Pocock Peter C G tzsche Jan P Vandenbroucke 赵乐(译) 邹光勇(审) 杜怀东(审) 2008世界临床医学2008,2,1:12
4超重与男性生殖能力研究进展:睡眠呼吸暂停,一个新领域显示文摘肥胖会对男性生殖产生负面影响,主要是因为肥胖与低睾酮水平和促性腺激素改变有关。男性肥胖已经被发现与男性生育力下降有关,但由于影响的性质和程度不同,肥胖与精子参数相关性的数据存在争议。一些新研究领域的出现,如遗传多态性和睡眠呼吸暂停,将有助于解释研究结果的差异性。已经发现睡眠紊乱与男性睾酮生成的变化和性腺功能低下有关,也可能与勃起功能障碍有关。睡眠紊乱与不育和精子参数的关系还有待研究。忠有性腺功能低下和不育的男性应该进行睡眠呼吸暂停症的筛查。对肥胖和睡眠呼吸暂停的治疗可以改善睾酮水平和勃起功能。Ahmad O Hammoud Douglas T Carrell Mark Gibson C Matthew Peterson A Wayne Meikle 2012Asian Journal of Andrology2012,14,1:11
5Hepatocellular carcinoma,human immunodeficiency virus and viral hepatitis in the HAART era显示文摘The incidence of hepatocellular carcinoma(HCC)in patients with human immunodeficiency virus(HIV) is rising.HCC in HIV almost invariably occurs in the context of hepatitis C virus(HCV)or hepatitis B virus (HBV)co-infection and,on account of shared modes of transmission,this occurs in more than 33% and 10% of patients with HIV worldwide respectively.It has yet to be clearly established whether HIV directly accelerates HCC pathogenesis or whether the rising incidence is an epiphenomenon of the highly active antiretroviral therapy(HAART)era,wherein the increased longevity of patients with HIV allows long-term complications of viral hepatitis and cirrhosis to develop.Answering this question will have implications for HCC surveillance and the timing of HCV/HBV therapy,which in HIV co-infection presents unique challenges.Once HCC develops,there is growing evidence that HIV co-infection should not preclude conventional therapeutic strategies,including liver transplantation.Douglas C Macdonald Mark Nelson Mark Bower Thomas Powles 2008World Journal of Gastroenterology2008,14,11:9
6Osteoclastic and pleomorphic giant cell tumors of the pancreas:A review of clinical,endoscopic,and pathologic features显示文摘Giant cell tumors of the pancreas come in three varieties-osteoclastic,pleomorphic,and mixed histology.These tumors have distinctive endoscopic,clinical,and cytological features.Giant cell tumors have a controversial histogenesis,with some authors favoring an epithelial origin and others favoring a mesenchymal origin.The true origin of these lesions remains unclear at this time.These are also very rare tumors but proper identification and differentiation from more common pancreatic adenocarcinoma is important.The risk factors of these tumors and the prognosis may be different from those associated with standard pancreatic adenocarcinoma.Recognition of these differences can significantly affect patient care.These lesions have a unique appearance when imaged with endoscopic ultrasound(EUS),and these lesions can be diagnosed via EUS guided Fine Needle Aspiration(FNA).This manuscript will review the endoscopic,clinical,and pathologic features of these tumors.Jill C Moore Joel S Bentz Kristen Hilden Douglas G Adler 2010World Journal of Gastrointestinal Endoscopy2010,2,1:7

9Posterior partially edentulous jaws, planning a rehabilitation with dental implants显示文摘AIM: To discuss important characteristics of the useof dental implants in posterior quadrants and the rehabilitation planning. METHODS: An electronic search of English articles was conducted on MEDLINE(PubM ed) from 1990 up to the period of March 2014. The key terms were dental implants and posterior jaws, dental implants/treatment planning and posterior maxilla, and dental implants/treatment planning and posterior mandible. No exclusion criteria were used for the initial search. Clinical trials, randomized and non randomized studies, classical and comparative studies, multicenter studies, in vitro and in vivo studies, case reports, longitudinal studies and reviews of the literature were included in this review. RESULTS: One hundred and fifty-two articles met the inclusion criteria of treatment planning of dental implants in posterior jaw and were read in their entirety. The selected articles were categorized with respect to their context on space for restoration, anatomic considerations(bone quantity and density), radiographic techniques, implant selection(number, position, diameter and surface), tilted and pterygoid implants, short implants, occlusal considerations, and success rates of implants placed in the posterior region. The results derived from the review process were described under several different topic headings to give readers a clear overview of the literature. In general, it was observed that the use of dental implants in posterior region requires a careful treatment plan. It is important that the practitioner has knowledge about the theme to evaluate the treatment parameters. CONCLUSION: The use of implants to restore the posterior arch presents many challenges and requires a detailed treatment planning.Douglas R Monteiro Emily V F Silva Eduardo P Pellizzer Osvaldo Magro Filho Marcelo C Goiato 2015World Journal of Clinical Cases2015,3,1:6

11Australian tertiary care outcomes of entecavir monotherapy in treatment naive patients with chronic hepatitis B显示文摘AIM:To evaluate the long-term treatment outcomes of entecavir monotherapy in treatment naive patients in an Australian tertiary care setting. METHODS:A retrospective analysis of treatment naive patients receiving entecavir monotherapy through Westmead Hospital was performed.Patients were excluded if they had received previous treatment with another nucleoside or nucleotide analogue,were pregnant or less than 18 years old. RESULTS:Out of 336 patients,163 patients fulfilled the selection criteria.Range of follow up was 3-46 mo (mean 26 mo).134 patients(82.2%)had pre-treatment biopsies,with 26 patients(16.0%)demonstrating F3-4 fibrosis.In total,153 patients(93.9%)achieved at least Partial Virological Suppression(PVS),with 134 patients (82.2%)achieving complete virological suppression. The cumulative CVS and PVS rates at 36 mo were 82.1%and 96.4%,respectively.3 patients(1.8%)failed to achieve PVS,while 5 patients(3.0%)developed virological rebound.128 patients(78.5%)maintained CVS throughout follow up.Predictors of CVS included lower baseline DNA level(P=0.001),hepatitis B virus e antigen negative status(P=0.001)and increasing age at treatment(log rank 0.001).No significant adverse effects were reported necessitating cessation of entecavir. CONCLUSION:Entecavir monotherapy is efficacious and safe in an Australian tertiary care setting.Resistance and rebound rates are very low.This is similar to data from controlled and uncontrolled trials around the world.Farzan Fahrtash-Bahin Viraj C Kariyawasam Timothy Gray Karen Byth Jacob George Mark W Douglas 2013World Journal of Gastroenterology2013,19,5:5
12Long-term stabilization of stage 4 colon cancer using sodium dichloroacetate therapy显示文摘Oral dichloroacetate sodium(DCA) has been investigated as a novel metabolic therapy for various cancers since 2007, based on data from Bonnet et al that DCA can trigger apoptosis of human lung, breast and brain cancer cells. Response to therapy in human studies is measured by standard response evaluation criteria for solid tumours definitions, which define 'response' by the degree of tumour reduction, or tumour disappearance on imaging. However, Blackburn et al have demonstrated that DCA can also act as a cytostatic agent in vitro and in vivo, without causing apoptosis(programmed cell death). A case is presented in which oral DCA therapy resulted in tumour stabilization of stage 4 colon cancer in a 57 years old female for a period of nearly 4 years, with no serious toxicity. Since the natural history of stage 4 colon cancer consists of steady progression leading to disability and death, this case highlights a novel use of DCA as a cytostatic agent with a potential to maintain long-term stability of advanced-stage cancer.Akbar Khan Douglas Andrews Anneke C Blackburn 2016World Journal of Clinical Cases2016,4,10:4
13Nutritional and health benefits of semi-elemental diets: A comprehensive summary of the literature显示文摘AIM:To critically review and summarize the literature on nutritional and health outcomes of semi-elemental formulations on various nutritionally vulnerable patient populations who are unable to achieve adequate nutrition from standard oral diets.METHODS:We conducted a comprehensive literature search of Pubmed and Embase databases.We manually screened articles that examined nutritional and health outcomes(e.g.,growth,disease activity,gastrointestinal impairment,mortality,and economic impact)among various patient groups receiving semi-elemental diets.This review focused on full-text articles of randomized controlled clinical trials and other intervention studies,but pertinent abstracts and case studies were also included.Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population in this systematic review.RESULTS:Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population.The efficacy of semi-elemental whey hydrolyzed protein(WHP)diet have been reported in various nutritionally high risk patient populations including-Crohn’s disease,short bowel syndrome,acute and chronic pancreatitis,cerebral palsy,cystic fibrosis,cerebrovascular accidents,human immunodeficiency virus,critically ill,and geriatrics.Collectively,the evidence from the medical literature indicates that feeding with a semi-elemental diet performs as well or better than parenteral or amino acid based diets in terms of toler-ance,digestion,and nutrient assimilation measures across various disease conditions.CONCLUSION:Based on this comprehensive review of the literature,patient populations who have difficulty digesting or absorbing standard diets may be able to achieve improved health and nutritional outcomes through the use of semi-elemental WHP diets.Dominik D Alexander Lauren C Bylsma Laura Elkayam Douglas L Nguyen 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,2:3
14Reuse of liver grafts following the brain death of the initial recipient显示文摘AIM: To determine if there is a reasonable prospect of success of a re-use liver transplantation.METHODS: We systematically searched for reports of liver graft re-use using electronic searches of PubMed and Web of Knowledge. We performed hand searches of references lists of articles reporting re-use of grafts.RESULTS: A systematic review of the literature reveals 28 liver transplantations using previously transplanted grafts. First and second recipients ranged in age from 4 to 72 years and 29 to 62 years respectively. Liver disease in the first recipient was varied including 5(18%) patients with fulminant liver failure who died subsequently of cerebral edema. The second transplanta-tion was performed after a median interval of 5 d(one day-13 years). Viral hepatitis was present in 3(11%) of the initial recipients and in 8(29%) of final recipients. Hepatocellular carcinoma was present in 6(21%) of the final recipients. Early survival after the final transplantation was 93%, whereas long-term survival was 78% with a mean follow-up of 23.3(3-120) mo.CONCLUSION: Outcomes of transplantation using previously transplanted grafts in this select population are similar to those seen with conventional grafts.Hideaki Tanaka Vivian C McAlister Mark A Levstik Cameron N Ghent Paul J Marotta Douglas Quan William J Wall 2014World Journal of Hepatology2014,6,6:3
