1Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis.Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak 2015World Journal of Gastroenterology2015,21,12:14

3Research advances on the multiple uses of Moringa oleifera: a sustainable alternative for socially neglected population显示文摘Moringa oleifera Lam(Moringaceae) is a plant with high nutritional and medicinal value. Native to India, it is now widely distributed throughout tropical and subtropical regions of the world. Its different parts are sources of proteins, vitamins and minerals and present different pharmacological and biotechnological potential. Moreover, M. oleifera seeds are widely used in water and effluent treatment, for their coagulation, flocculation and sedimentation properties, their ability of improving water quality, by reducing organic matter and microbial load, with special applicability in intensive animal production systems, such as aquaculture. In addition, due to its high nutritional value and several medicinal properties, this tree may act as a nutritional and medical alternative for socially neglected populations. In this context, this review gathers information on M. oleifera, emphasizing its chemical constituents, nutritional, pharmacological and antimicrobial properties, applications in the treatment of water effluents, and ecological and social aspects.Raimunda Samia Nogueira Brilhante Jamille Alencar Sales Vandbergue Santos Pereira Débora de Souza Collares Maia Castelo-Branco Rossana de Aguiar Cordeiro Célia Maria de Souza Sampaio Manoel de Araújo Neto Paiva Joao Bosco Feitosa dos Santos JoséJúlio CostaSidrim Marcos Fábio Gadelha Rocha 2017Asian Pacific Journal of Tropical Medicine2017,10,7:10
4Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,10:5
5从附睾到卵子:CRISP蛋白在哺乳动物受精过程中的作用显示文摘哺乳动物的受精过程涉及精卵结合的很多步骤,是一个非常复杂的过程,其分了机制亟待阐明。此篇综述主要论述了CRISP(富含半胱氨酸的分泌蛋白)作为模型分子在哺乳动物受精过程中的价值。大量的体外实验和基因敲出模型研究显示,附睾内的CRISP1以两种不同的亲和力结合于精子表面,参与精子获能、精子-透明带结合、精卵融合的调控。这些研究成果可以延伸至人类。我们住研究中发现,人类具有与啮齿类同源的CRISP(hCRISP1),同样参与受精过样。CRISP家族的其他成员(睾丸内CRISP2、附挈内CRISP3—4、射精时的CRISP3)也参与了精卵结合的过程,提示同源分子间的相互协同有助于受精的成功。另外,我们的研究显示,CRISP蛋白伴随精子穿越男性及女性生殖管道的全过程。我们推测CRISP不仅参与了受精过程,而且可能成为不育和避孕研究的新靶点。Vanina G Da Ros Mariana Weigel Munoz Maria A Battistone Nicolas G Brukman Guillermo Carvajal Ludmila Curci Matlas D Gomez-Elias Debora J Cohen Patricia S Cuasnicu 2015Asian Journal of Andrology2015,17,5:5
6Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari 2019World Journal of Gastroenterology2019,25,38:2
7Oral refeeding in mild acute pancreatitis:An old challenge显示文摘Although the idea that pancreas rest has long been considered as a very relevant topic in acute pancreatitis (AP)therapy,the right time and type of diet to be offered to patients recovering from an acute attack are a great challenge to clinicians who treat this condition.Fortunately,the last decade was noted for several trials looking for the best answer to the question:'when and how to start oral refeeding in AP?'It is well known that 80%of patients present with mild disease characterized by usually uncomplicated clinical course are managed with pancreatic rest through nil per oral;while the use of specific nutritional intervention is an exception.Therefore,mild AP has been the most investigated form of AP and researchers have tried different kind of meals to offer calories and reduce costs by shortening hospitalization time.Usually in mild AP,the oral refeeding is introduced between the first 3 d and 7 d after hospitalization but,the type of diet and patients’tolerance have been scrutinized in detail with mixed results.Although 20%to 25%have pain recurrence requiring nutritional support and greater time of hospitalization,most patients seem to tolerate oral refeeding well.We propose analyzing the most recent investigations of this matter and their conclusions to develop a better understanding of the management of AP.Júlio Maria F Chebli Pedro D Gaburri Liliana A Chebli 2011World Journal of Gastrointestinal Pathophysiology2011,2,6:2
8抑郁症的非药物治疗:系统性综述与证据图显示文摘背景抑郁症非药物治疗的疗效比较目前仍然不清楚。方法我们对一些系统性综述作了概述,回顾了随机对照试验(RCT),比较抑郁症非药物治疗的有效性和认知行为治疗(CBT)。对多个电子数据库在2016年2月之前发表的所有文献进行了检索,不限制语言。成对的评阅人进行资料纳入、数据提炼并评估偏倚的风险。在适用的时候进行了荟萃分析。结果我们收录了367项RCT,纳入了约2000名患者,进行了11种治疗,导出17项独立的头对头比较。通过标准化的量表评估,发现CBT、自然疗法、行为干预与躯体活动干预可以降低抑郁的严重程度。然而,这些非药物干预的相对疗效仍然缺乏。这些干预对临床缓解和复发的效果不清楚。CBT的发生率比抗抑郁药物更低。局限性由于证据缺乏一致性、证据不清或偏倚风险高,导致证据的质量只是低到中等,限制了我们研究结果的可信度。结论抑郁症的非药物治疗能减少抑郁症状,在轻度到重度抑郁症患者中,应当合并抗抑郁药物治疗,一同进行。对于非药物治疗的选择,应当根据患者的价值观、偏好、临床和社会因素来与患者共同作出决定。Wigdan H Farah Mouaz Alsawas Maria Mainou Fares Alahdab Magdoleen H Farah Ahmed T Ahmed Essa A Mohamed Jehad Almasri Michael R Gionfriddo Ana Castaneda-Guarderas Khaled Mohammed Zhen Wang Noor Asi Craig N Sawchuk Mark D Williams Larry J Prokop M Hassan Murad Annie LeBlanc 2017英国医学杂志中文版2017,20,11:2
