1Transhiatal versus transthoracic esophagectomy for esophageal cancer显示文摘Esophageal cancer continues to represent a formidable challenge for both patients and clinicians. Relative 5-year survival rates for patients have improved over the past three decades, probably linked to a combination of improved surgical outcomes, progress in systemic chemotherapy and radiotherapy, and the increasing acceptance of multimodality treatment. Surgical treatment remains a fundamental component of the treatment of localized esophageal adenocarcinoma. Multiple approaches have been described for esophagectomy, which can be thematically grouped under two major categories: either transthoracic or transhiatal. The main controversy rests on whether a more extended resection through thoracotomy provides superior oncological outcomes as opposed to resection with relatively limited morbidity and mortality through a transhiatal approach. After numerous trials have addressed these issues, neither approach has consistently proven to be superior to the other one, and both can provide excellent short-term results in the hands of experienced surgeons. Moreover, the available literature suggests that experience of the surgeonand hospital in the surgical management of esophageal cancer is an important factor for operative morbidity and mortality rates, which could supersede the type of approach selected. Oncological outcomes appear to be similar after both procedures.J Camilo Barreto Mitchell C Posner 2010World Journal of Gastroenterology2010,16,30:16
2物种分布模型在古生物学研究中的应用显示文摘物种分布模型(Species distribution models,SDMs)是基于物种的生态位要求,通过将物种已知的分布数据和对应地区的环境数据联系起来,以预测该物种在不同时间和空间下的地理分布的一种数学工具。它为地史时期生物地理分布的重建、生物生态特征的分析及生物与地球环境协同演化研究等提供了一种新的途径。此方法具有研究精度高、预测效果好及应用广泛等优点,尤其适合开展高精度的古生物地理、古生态及生物宏演化等相关研究。文章着重介绍物种分布模型的基本原理及建模流程,在此基础上以笔石种Tang yagraptus typicus Mu作为建模实例进一步说明物种分布建模的详细步骤,最后概述此方法在古生物研究中的适用性及存在的问题。张琳娜 樊隽轩 Melchin M J 陈清 Wu Shuang-ye Goldman D Mitchell C M Sheets H D 2013古生物学报2013,52,2:6
3Gastroenterologist perceptions of faecal microbiota transplantation显示文摘AIM: To explore gastroenterologist perceptions towards and experience with faecal microbiota transplantation(FMT).METHODS: A questionnaire survey consisting of 17 questions was created to assess gastroenterologists' attitude towards and experience with FMT. This was anonymously distributed in hard copy format amongst attendees at gastroenterology meetings in Australia between October 2013 and April 2014. Basic descriptive statistical analyses were performed.RESULTS: Fifty-two clinicians participated. Twenty one percent had previously referred patients for FMT,8% more than once. Ninety percent would refer patients with Clostridium difficile infection(CDI) for FMT if easily available,37% for ulcerative colitis,13% for Crohn's disease and 6% for irritable bowel syndrome. Six percent would not refer any indication,including recurrent CDI. Eighty-six percent would enroll patients in FMT clinical trials. Thirty-seven percent considered the optimal mode of FMT administration transcolonoscopic,17% nasoduodenal,13% enema and 8% oral capsule. The greatest concerns regarding FMT were: 42% lack of evidence,12% infection risk,10% non infectious adverse effects/lack of safety data,10% aesthetic,10% lack of efficacy,4% disease exacerbation,and 2% inappropriate use; 6% had no concerns. Seventy seven percent believed there is a lack of accessibility while 52% had an interest in learning how to provide FMT. Only 6% offered FMT at their institution.CONCLUSION: Despite general enthusiasm,most gastroenterologists have limited experience with,or access to,FMT. The greatest concerns were lack of supportive evidence and safety issues. However a significant proportion would refer indications other than CDI for FMT despite insufficient evidence. These data provide guidance on where education and training are required.Sudarshan Paramsothy Alissa J Walsh Thomas Borody Douglas Samuel Johan van den Bogaerde Rupert WL Leong Susan Connor Watson Ng Hazel M Mitchell Nadeem O Kaakoush Michael A Kamm 2015World Journal of Gastroenterology2015,21,38:5
4中年成人平均动脉压的体位改变与动脉硬度的关系:Framingham心脏研究显示文摘Torjesen A, Cooper LL, Rong J, Larson MG, Hamburg NM, Levy D, Benjamin EJ, Vasan RS, Mitchell GF. Relations of arterial stiffness with postural change in mean arterial pressure in middle-aged adults:the Framingham heart study. Hyperten- sion,2017,69(4) :685-690.站立位血压稳定调节受损可导致不良结果,包括跌倒、晕厥和定向障碍。平均动脉压(meanarterialpressure,MAP)通常在站立位时增加,然而,站立位MAP增加不足或减少可能导致脑灌注减少。已有研究报道,在动脉硬度增加的老年人中存在体位性低血压,年轻至中年人MAP的体位性改变与动脉硬度的相关性尚未阐明。该研究分析了Framingham心脏研究第3代队列中的受试者3205人(女性1693人,占53%)的直立性血压反应和全面血液动力学数据。Torjesen A Cooper LL Rong J Larson MG Hamburg NM Levy D Benjamin EJ Vasan RS Mitchell GF 刘莉 叶鹏 2017中华高血压杂志2017,25,3:5

6Persistent risk for new, subsequent new and recurrent hepatocellular carcinoma despite successful anti-hepatitis B virus therapy and tumor ablation: The need for hepatitis B virus cure显示文摘Hepatitis B virus(HBV) is one of the most significant hepatocarcinogens. The ultimate goal of anti-HBV treatment is to prevent the development of hepatocellular carcinoma(HCC). During the last two decades, with the use of currently available anti-HBV therapies(lamivudine, entecavir and tenofovir disoproxil fumatate), there has been a decrease in the incidence of HBVassociated HCC(HBV-HCC). Furthermore, several studies have demonstrated a reduction in recurrent or new HCC development after initial HCC tumor ablation. However, during an observation period spanning 10 to 20 years, several case reports have demonstrated the development of new, subsequent new and recurrent HCC even in patients with undetectable serum HBV DNA. The persistent risk for HCC is attributed to the presence of covalently closed circular DNA(cccDNA) in the hepatocyte nucleus which continues to work as a template for HBV replication. While a functional cure(loss of hepatitis B surface antigen and undetectable viral DNA) can be attained with nucleos(t)ide analogues, these therapies do not eliminate cccDNA. Of utmost importance is successful eradication of the transcriptionally active HBV cccDNA from hepatocyte nuclei which would be considered a complete cure. The unpredictable nature of HCC development in patients with chronic HBV infection shows the need for a complete cure. Continued support and encouragement for research efforts aimed at developing curative therapies is imperative. The aims of this minireview are to highlight these observations and emphasize the need for a cure for HBV.Brianna J Shinn Aaron Martin Robert M Coben Mitchell I Conn Jorge Prieto Howard Kroop Anthony J DiMarino Hie-Won Hann 2019World Journal of Hepatology2019,11,1:3
7Application of positron emission tomography/computed tomography in radiation treatment planning for head and neck cancers显示文摘18-fluorodeoxygluocose positron emission tomography/computed tomography(18FDG-PET/CT) provides significant information in multiple settings in the management of head and neck cancers(HNC). This article seeks to define the additional benefit of PET/CT as related to radiation treatment planning for squamous cell carcinomas(SCCs) of the head and neck through a review of relevant literature. By helping further define both primary and nodal volumes, radiation treatment planning can be improved using PET/CT. Special attention is paid to the independent benefit of PET/CT in targeting mucosal primaries as well as in detecting nodal metastases. The utility of PET/CT is also explored for treatment planning in the setting of SCC of unknown primary as PET/CT may help define a mucosal target volume by guiding biopsies for examination under anesthesia thus changing the treatment paradigm and limiting the extent of therapy. Implications of the use of PET/CT for proper target delineation in patients with artifact from dental procedures are discussed and the impact of dental artifact on CT-based PET attenuation correction is assessed. Finally, comment is made upon the role of PET/CT in the high-risk post-operative setting, particularly in the context of radiation dose escalation. Real case examples are used in these settings to elucidate the practical benefits of PET/CT as related to radiation treatment planning in HNCs.Musaddiq J Awan Farzan Siddiqui David Schwartz Jiankui Yuan Mitchell Machtay Min Yao 2015World Journal of Radiology2015,7,11:2
