1Fecal microbiota transplantation as novel therapy in gastroenterology:A systematic review显示文摘AIM:To study the clinical efficacy and safety of Fecal microbiota transplantation(FMT).We systematically reviewed FMT used as clinical therapy.METHODS:We searched MEDLINE,EMBASE,the Cochrane Library and Conference proceedings from inception to July,2013.Treatment effect of FMT was calculated as the percentage of patients who achieved clinical improvement per patient category,on an intention-to-treat basis.RESULTS:We included 45 studies;34 on Clostridium difficile-infection(CDI),7 on inflammatory bowel disease,1 on metabolic syndrome,1 on constipation,1 on pouchitis and 1 on irritable bowel syndrome(IBS).In CDI 90% resolution of diarrhea in 33 case series(n = 867) was reported,and 94% resolution of diarrhea after repeated FMT in a randomized controlled trial(RCT)(n = 16).In ulcerative colitis(UC) remission rates of 0% to 68% were found(n = 106).In Crohn's disease(CD)(n = 6),no benefit was observed.In IBS,70% improvement of symptoms was found(n = 13).100% Reversal of symptoms was observed in constipation(n = 3).In pouchitis,none of the patients(n = 8) achieved remission.One RCT showed significant improvement of insulin sensitivity in metabolic syndrome(n = 10).Serious adverse events were rare.CONCLUSION:FMT is highly effective in CDI,and holds promise in UC.As for CD,chronic constipation,pouchitis and IBS data are too limited to draw conclusions.FMT increases insulin sensitivity in metabolic syndrome.Noortje G Rossen John K Mac Donald Elisabeth M de Vries Geert R D'Haens Willem M de Vos Erwin G Zoetendal Cyriel Y Ponsioen 2015World Journal of Gastroenterology2015,21,17:41
2帕博利珠单抗单用或与放疗联用治疗转移性非小细胞肺癌:两个随机试验的汇总分析显示文摘背景放疗可以提高整个机体对免疫治疗的应答。在Ⅱ期PEMBRO-RT研究和Ⅰ/Ⅱ期MDACC研究中,患有转移性非小细胞肺癌(NSCLC)的患者被随机分配入组,接受免疫治疗(帕博利珠单抗)+放疗联合疗法,或免疫治疗单一疗法。当上述2个研究单独分析时,联合疗法组显示出潜在获益。由于每个研究的样本量较小,缓解率和结局并未显示出统计学意义,然而却有显著的临床获益。因此,本研究进行汇总分析,来判断放疗是否会改善转移性NSCLC患者的免疫治疗应答。方法PEMBRO-RT和MDACC研究纳入标准:患者年龄≥18岁,患有转移性NSCLC,且有≥1处未经放疗照射的病灶,以便进行射野外应答监测。PEMBRO-RT研究纳入曾接受过化疗患者,MDACC研究纳入曾接受过治疗或新诊断患者。2个研究中的患者均未接受过免疫治疗。在PEMBRO-RT研究中患者被等比例随机分配入组,并根据吸烟状态进行分层(分为<10年组和≥10年组)。MDACC研究的患者根据放疗计划可行性被等比例随机分配入2个受试组。由于联合治疗组的干预本质,每个研究中的放疗均不适用盲法。在2个研究中,不论是否进行放疗,均静脉滴入帕博利珠单抗(每3周200 mg)。在PEMBRO-RT研究中,在放疗(24 Gy 3次分割照射)结束后1周给予第1剂帕博利珠单抗。在MDACC研究中,在第1次放疗(50 Gy 4次分割照射或45 Gy 15次分割照射)同时给予帕博利珠单抗。仅检测未经照射病灶的应答。本研究的终点为最佳射野外(远隔)应答率(ARR)、最佳射野外疾病控制率(ACR)、12周时ARR、12周时ACR、无进展生存期(PFS)和总生存期(OS)。2个研究的意向治疗(ITT)人群均纳入分析。PEMBRO-RT研究(NCT02492568)和MDACC研究(NCT02444741)均在ClinicalTrials.gov上注册。发现纳入148例患者,76例接受帕博利珠单抗治疗,72例接受帕博利珠单抗+放疗治疗。所有患者随访时间中位数为33个月[四分位距(IQR):32.4~33.6]。148例患者中124例(84%)组织学特征为非鳞癌,111例(75%)患者曾经接受过化疗。组间没有基线特征差异,包括PD-L1表达状态和转移灶体积。最常见的照射部位为肺转移灶(39%,28/72)、胸腔内淋巴结(21%,15/72)和非原发灶(17%,12/72)。帕博利珠单抗组和联合治疗组的最佳ARR分别为19.7%(15/76)和41.7%(30/72),OR=2.96,95%CI:1.42~6.20,P=0.0039;最佳ACR分别为43.4%(33/76)和65.3%(47/72),OR=2.51,95%CI:1.28~4.91,P=0.0071;PFS中位数分别为4.4(IQR:2.9~5.9)和9.0个月(IQR:6.8~11.2),HR=0.67,95%CI:0.45~0.99,P=0.045;OS中位数分别为8.7(IQR:6.4~11.0)和19.2个月(IQR:14.6~23.8),OR=0.67,95%CI:0.54~0.84,P=0.0004。在汇总分析中没有发现新的安全问题。解读帕博利珠单抗免疫疗法+放疗显著提高转移性NSCLC患者的应答和改善治疗结局。这些结果需要在三期临床试验中进行验证。陈大卫(翻译) 于金明(校对) Willemijn S M E Theelen Vivek Verma Brian P Hobbs Heike M U Peulen Joachim G J V Aerts Idris Bahce Anna Larissa N Niemeijer Joe Y Chang Patricia M de Groot Quynh-Nhu Nguyen Nathan I Comeaux George R Simon Ferdinandos Skoulidis Steven H Lin Kewen He Roshal Patel John Heymach Paul Baas James W Welsh 2021中华肿瘤防治杂志2021,28,24:49

6Establishing proof of concept:Platelet-rich plasma and bone marrow aspirate concentrate may improve cartilage repair following surgical treatment for osteochondral lesions of the talus显示文摘Osteochondral lesions of the talus are common injuries in the athletic patient. They present a challenging clinical problem as cartilage has a poor potential for healing. Current surgical treatments consist of reparative(microfracture) or replacement(autologous osteochondral graft) strategies and demonstrate good clinical outcomes at the short and medium term follow-up. Radiological findings and second-look arthroscopy however, indicate possible poor cartilage repair with evidence of fibrous infill and fissuring of the regenerative tissue following microfracture. Longer-term follow-up echoes these findings as it demonstrates a decline in clinical outcome. The nature of the cartilage repair that occurs for an osteochondral graft to become integrated with the native surround tissue is also of concern. Studies have shown evidence of poor cartilage integration,with chondrocyte death at the periphery of the graft, possibly causing cyst formation due to synovial fluid ingress. Biological adjuncts, in the form of platelet-rich plasma(PRP) and bone marrow aspirate concentrate(BMAC), have been investigated with regard to their potential in improving cartilage repair in both in vitro and in vitro settings. The in vitro literature indicates that these biological adjuncts may increase chondrocyte proliferation as well as synthetic capability, while limiting the catabolic effects of an inflammatory joint environment. These findings have been extrapolated to in vitro animal models, with results showing that both PRP and BMAC improve cartilage repair. The basic science literature therefore establishes the proof of concept that biological adjuncts may improve cartilage repair when used in conjunction with reparative and replacement treatment strategies for osteochondral lesions of the talus.Niall A Smyth Christopher D Murawski Amgad M Haleem Charles P Hannon Ian Savage-Elliott John G Kennedy 2012World Journal of Orthopedics2012,3,7:8
7Platelet-rich plasma increases transforming growth factor-beta1 expression at graft-host interface following autologous osteochondral transplantation in a rabbit model显示文摘AIM: To explore the effect of platelet-rich plasma on protein expression patterns of transforming growth factor-beta1(TGF-β1) in cartilage following autologous osteochondral transplantation(AOT) in a rabbit knee cartilage defect model.METHODS: Twelve New Zealand white rabbits received bilateral AOT. In each rabbit, one knee was randomized to receive an autologous platelet rich plasma(PRP) injection and the contralateral knee received saline injection. Rabbits were euthanized at 3, 6 and 12 wk post-operatively. Articular cartilage sections were stained with TGF-β1 antibody. Histological regions of interest(ROI)(left, right and center of the autologous grafts interfaces) were evaluated using Meta Morph. Percentage of chondrocytes positive for TGF-β1 was then assessed.RESULTS: Percentage of chondrocytes positive for TGF-β1 was higher in PRP treated knees for selected ROIs(left; P = 0.03, center; P = 0.05) compared to control and was also higher in the PRP group at each post-operative time point(P = 6.6 × 10^(-4), 3.1 × 10^(-4) and 7.3 × 10^(-3) for 3, 6 and 12 wk, respectively). TGF-β1 expression was higher in chondrocytes of PRP-treated knees(36% ± 29% vs 15% ± 18%)(P = 1.8 × 10^(-6)) overall for each post-operative time point and ROI. CONCLUSION: Articular cartilage of rabbits treated with AOT and PRP exhibit increased TGF-β1 expression compared to those treated with AOT and saline. Our findings suggest that adjunctive PRP may increase TGF-β1 expression, which may play a role in the chondrogenic effect of PRP in vivo.Lorraine A Boakye Keir A Ross John M Pinski Niall A Smyth Amgad M Haleem Charles P Hannon Lisa A Fortier John G Kennedy 2015World Journal of Orthopedics2015,6,11:7
8针对患者利益的机器学习和人工智能研究:在透明性、可重复性、伦理和有效性等方面的20个关键问题显示文摘机器学习(ML)、人工智能(AI)和其他现代统计方法正为利用先前尚未开发且极速增长的数据资源提供新的机会,以期让患者获益。尽管目前正在进行许多有前景的研究,特别是在图像方面,但就文献整体而言还缺乏透明度、对可重复性清晰的阐述、对潜在伦理问题的探究,以及对有效性的明确验证。这些问题的存在有许多原因,其中最重要的一点(为此我们提供了初步解决方案)就是当前缺乏针对ML和AI的最佳实践指南。我们认为从事研究的跨学科团队和应用ML/AI影响健康的项目,将因解决有关透明度、可重复性、伦理和有效性(TREE)的一系列问题而受益。这里提出的20个关键问题为研究团队提供了一个研究设计、实施和报告框架;帮助编辑和同行评审专家评估文献的贡献;让患者、临床医生和政策制定者评估新发现可能会给患者带来的获益。Sebastian Vollmer Bilal A Mateen Gergo Bohner Franz J Kirdly Rayid Ghani Pall Jonsson Sarah Cumbers Adrian Jonas Katherine S L McAllister Puja Myles David Granger Mark Birse Richard Branson Karel G M Moons Gary S Collins John P A Chris Holmes Harry Hemingwayp 李峰(译) 徐磊(校) 赵邑(校) 2020英国医学杂志中文版2020,23,9:5
9Use of the Endocuff during routine colonoscopy examination improves adenoma detection: A meta-analysis显示文摘AIM To perform meta-analysis of the use of Endocuff during average risk screening colonoscopy.METHODS Scopus, Cochrane databases, MEDLINE/Pub Med, and CINAHL were searched in April 2016. Abstracts from Digestive Disease Week, United European Gastroenterology, and the American College of Gastroenterology meeting were also searched from 2004-2015. Studies comparing EC-assisted colonoscopy(EAC) to standard colonoscopy, for any indication, were included in the analysis. The analysis was conducted by using the Mantel-Haenszel or DerS imonian and Laird models with the odds ratio(OR) to assess adenoma detection, cecal intubation rate, and complications performed. RESULTS Nine studies(n = 5624 patients) were included in the analysis. Compared to standard colonoscopy, procedures performed with EC had higher frequencies for adenoma(OR = 1.49, 95%CI: 1.23-1.80; P = 0.03), and sessile serrated adenomas detection(OR = 2.34 95%CI: 1.63-3.36; P < 0.001). There was no significant difference in cecal intubation rates between the EACgroup and standard colonoscopy(OR = 1.26, 95%CI: 0.70-2.27, I2 = 0%; P = 0.44). EAC was associated with a higher risk of complications, most commonly being superficial mucosal injury without higher frequency for perforation.CONCLUSION The use of an EC on colonoscopy appears to improve pre-cancerous polyp detection without any difference in cecal intubation rates compared to standard colonoscopy.Matthew Chin William Karnes M Mazen Jamal John G Lee Robert Lee Jason Samarasena Matthew L Bechtold Douglas L Nguyen 2016World Journal of Gastroenterology2016,22,43:4
10Cytoplasmic expression of p27^(kip1) is associated with a favourable prognosis in colorectal cancer patients显示文摘AIM: To evaluate the prognostic significance of p27kip1 in colorectal cancer patients. METHODS: Cytoplasmic and nuclear p27kip1 expression was evaluated in 418 colorectal cancers using tissue microarrays. Data were associated with known patient and tumor variables and long-term patient outcomes, providing further insight into the mechanisms by which p27kip1 may influence tumor development. RESULTS: Nuclear and cytoplasmic p27Kip1 expressions were detected in 59% and 19% of tumors respectively. Cytoplasmic p27Kip1 was almost invariably associated with positive nuclear p27Kip1 expression. Neither case correlat- ed with known clinical or pathological variables, includ- ing tumor stage, grade or extramural vascular invasion. Furthermore, nuclear p27kip1 expression had no impact on survival. However, we identified a significant correla- tion between expression of cytoplasmic p27kip1 and longer disease-specific survival times. On multivariate analysis, TNM stage and extramural vascular invasion were highly significant independent prognostic factors, with positive cytoplasmic p27 expression showing a trend towards im- proved patient survival (P = 0.059).CONCLUSION: These findings support the recent evi- dence that cytoplasmic p27kip1 has a distinct and impor- tant biological role that can influence tumor outcome.Nicholas FS Watson Lindy G Durrant John H Scholefield Zahra Madjd Duncan Scrimgeour Ian Spendlove Ian O Ellis Poulam M Patel 2006World Journal of Gastroenterology2006,12,39:3

12Tumor necrosis factor-α-induced protein 1 and immunity to hepatitis B virus显示文摘AIM: To compare the gene expression profile in a pair of HBV-infected twins.METHODS: The gene expression profile was compared in a pair of HBV-infected twins.RESULTS: The twins displayed different disease outcomes. One acquired natural immunity against HBV,whereas the other became a chronic HBV carrier. Eightyeight and forty-six genes were found to be up- or downregulated in their PBMCs, respectively. Tumor necrosis factor-alpha-induced protein 1 (TNF-αIP1) that expressed at a higher level in the HBV-immune twins was identified and four pairs of siblings with HBV immunity by RTPCR. However, upon HBV core antigen stimulation,TNF-αIP1 was downregulated in PBMCs from subjects with immunity, whereas it was slightly upregulated in HBV carriers. Bioinformatics analysis revealed a K+channel tetramerization domain in TNF-αIP1 that shares a significant homology with some human, mouse, and C elegan proteins.CONCLUSION: TNF-αIP1 may play a role in the innate immunity against HBV.Marie C Lin Nikki P Lee Ning Zheng Pai-Hao Yang Oscar G Wong Hsiang-Fu Kung Chee-Kin Hui John M Luk George Ka-Kit Lau 2005World Journal of Gastroenterology2005,11,48:3
13澳大利亚初级保健诊所新发腰背痛患者的预后:起始队列研究显示文摘目的估计初级保健诊所内新发腰背痛患者的1年预后,并确定其预后因素。设计1年随访队列研究。地点澳大利亚悉尼的初级保健诊所。参试者初级保健诊所接诊的973例非特异性腰背痛连续患者(平均年龄43.3岁,男性54.8%)。该起始队列患者腰背痛时间不足两周,征集自170名全科医生、理疗师或按摩师诊所。主要评估指标参试者完成基线调查问卷后,分别于初次就诊后6周、3个月和21个月时复查评估。评估内容包括:工作恢复情况、功能恢复情况和疼痛消失情况。潜在预后因素与恢复所需时间的关联性用Cox回归建模分析。结果12个月随访率〉97%。基线时工作能力下降的患者半数在14天内恢复了以前的工作状态(95%可信区间11-17天),83%在3个月内恢复。残疾(中位恢复时间31天,25-37天)和疼痛(中位58天,52-63天)则需要较长的时间才能恢复。只有72%的受试者于基线访问后12个月获得完全康复。高龄、赔偿诉讼、疼痛较重、就诊前腰背痛时间较长、就诊前因疼痛活动减少天数较多、抑郁情绪以及预期危险持续与所需恢复时问较长相关。结论在这个急性腰背痛初级保健患者队列,患者的预后并不像临床指南声称的那样乐观。多数患者的恢复缓慢。近三分之一的患者在腰背痛发作后1年尚未恢复。Nicholas Henschke Christopher G Maher Kathryn M Refshauge Robert D Herbert Robert G Cumming Jane Bleasel John York Anurina Das James H McAuley 蓝恭涛(译) 2008英国医学杂志中文版2008,11,6:2
14Gastrointestinal and liver disease in patients with schizophrenia:A narrative review显示文摘Schizophrenia is a severe mental illness which can have a devastating impact onan individual’s quality of life. Comorbidities are high amongst patients and lifeexpectancy is approximately 15 years less than the general population. Despite thewell-known increased mortality, little is known about the impact of gastrointestinaland liver disease on patients with schizophrenia. We aimed to reviewthe literature and to make recommendations regarding future care. Literaturesearches were performed on PubMed to identify studies related to gastrointestinaland liver disease in patients with schizophrenia. High rates of chronic liverdisease were reported, with Non-Alcoholic Fatty Liver Disease being of particularconcern;antipsychotics and metabolic syndrome were contributing factors. Ratesof acute liver failure were low but have been associated with antipsychotic useand paracetamol overdose. Coeliac disease has historically been linked to schizophrenia;however, recent research suggests that a causal link is yet to be proven.Evidence is emerging regarding the relationships between schizophrenia andpeptic ulcer disease, inflammatory bowel disease and irritable bowel syndrome;clinical vigilance regarding these conditions should be high. Patients with schizophreniapoorly engage with bowel cancer screening programmes, leading to latediagnosis and increased mortality. Clozapine induced constipation is a significantissue for many patients and requires close monitoring. There is a significantburden of gastrointestinal and liver disease amongst patients with schizophrenia.Better levels of support from all members of the medical team are essential toensure that appropriate, timely care is provided.Rebecca K Grant William M Brindle Mhairi C Donnelly Pauline M McConville Thomas G Stroud Lorenzo Bandieri John N Plevris 2022World Journal of Gastroenterology2022,28,38:2
