| 1 | Role of mi RNAs and their potential to be useful as diagnostic and prognostic biomarkers in gastric cancer显示文摘Alterations in epigenetic control of gene expression play an important role in many diseases, including gastric cancer. Many studies have identified a large number of upregulated oncogenic mi RNAs and downregulated tumour-suppressor mi RNAs in this type of cancer. In this review, we provide an overview of the role of mi RNAs, pointing to their potential to be useful as diagnostic and/or prognostic biomarkers in gastric cancer. Moreover, we discuss the influence of polymorphisms and epigenetic modifications on mi RNA activity. | Kelly Cristina da Silva Oliveira Taíssa Maíra Thomaz Araújo Camila Inagaki Albuquerque Gabriela Alcantara Barata Carolina Oliveira Gigek Mariana Ferreira Leal Fernanda Wisnieski Fernando Augusto Rodrigues Mello Junior André Salim Khayat Paulo Pimentel de Assumpcao Rommel Mário Rodriguez Burbano Marília Cardoso Smith Danielle Queiroz Calcagno | 2016 | World Journal of Gastroenterology2016，22，35： | 11 |
| 2 | Management of nonalcoholic fatty liver disease:An evidence-based clinical practice review显示文摘AIM:To build a consensus among Chilean specialists on the appropriate management of patients with nonalcoholic fatty liver disease(NAFLD)in clinical practice.METHODS:NAFLD has now reached epidemic proportions worldwide.The optimal treatment for NAFLD has not been established due to a lack of evidence-based recommendations.An expert panel of members of the Chilean Gastroenterological Society and the Chilean Hepatology Association conducted a structured analysis of the current literature on NAFLD therapy.The quality of the evidence and the level of recommendations supporting each statement were assessed according to the recommendations of the United States Preventive Services Task Force.A modified three-round Delphi technique was used to reach a consensus among the experts.RESULTS:A group of thirteen experts was established.The survey included 17 open-ended questions that were distributed among the experts,who assessed the articles associated with each question.The levels of agreement achieved by the panel were 93.8%in the first round and 100%in the second and third rounds.The final recommendations support the indication of lifestyle changes,including diet and exercise,for all patients with NAFLD.Proven pharmacological therapies include only vitamin E and pioglitazone,which can be used in nondiabetic patients with biopsy-proven nonalcoholic steatohepatitis(the progressive form of NAFLD),although the long-term safety and efficacy of these therapies have not yet been established.CONCLUSION:Current NAFLD management is rapidly evolving,and new pathophysiology-based therapies are expected to be introduced in the near future.All NAFLD patients should be evaluated using a three-focused approach that considers the risks of liver disease,diabetes and cardiovascular events. | Juan P Arab Roberto Candia Rodrigo Zapata Cristián Mu?oz Juan P Arancibia Jaime Poniachik Alejandro Soza Francisco Fuster Javier Brahm Edgar Sanhueza Jorge Contreras M Carolina Cuellar Marco Arrese Arnoldo Riquelme | 2014 | World Journal of Gastroenterology2014，20，34： | 11 |
| 3 | Pathological aspects of so called 'hilar cholangiocarcinoma'显示文摘Cholangiocarcinoma(CC) arising from the large intrahepatic bile ducts and extrahepatic hilar bile ducts share clinicopathological features and have been called hilar and perihilar CC as a group.However,'hilar and perihilar CC' are also used to refer exclusively to the intrahepatic hilar type CC or,more commonly,the extrahepatic hilar CC.Grossly,a major distinction can be made between papillary and non-papillary tumors.Histologically,most hilar CCs are well to moderately differentiated conventional type(biliary) carcinomas.Immunohistochemically,CK7,CK20,CEA and MUC1 are normally expressed,being MUC2 positive in less than 50% of cases.Two main premalignant lesions are known:biliary intraepithelial neoplasia(BilIN) and intraductal papillary neoplasm of the biliary tract(IPNB).IPNB includes the lesions previously named biliary papillomatosis and papillary carcinoma.A series of 29 resected hilar CC from our archives is reviewed.Most(82.8%) were conventional type adenocarcinomas,mostly well to moderately differentiated,although with a broad morphological spectrum;three cases exhibited a poorly differentiated cell component resembling signet ring cells.IPNB was observed in 5(17.2%),four of them with an associated invasive carcinoma.A clear cell type carcinoma,an adenosquamous carcinoma and two gastric foveolar type carcinomas were observed. | Víctor M Castellano-Megías Carolina Ibarrola-de Andrés Francisco Colina-Ruizdelgado | 2013 | World Journal of Gastrointestinal Oncology2013，5，7： | 8 |
| 4 | Guillain–Barré syndrome, transverse myelitis and infectious diseases显示文摘Guillain–Barrésyndrome(GBS)and transverse myelitis(TM)both represent immunologically mediated polyneuropathies of major clinical importance.Both are thought to have a genetic predisposition,but as of yet no specific genetic risk loci have been clearly defined.Both are considered autoimmune,but again the etiologies remain enigmatic.Both may be induced via molecular mimicry,particularly from infectious agents and vaccines,but clearly host factor and co-founding host responses will modulate disease susceptibility and natural history.GBS is an acute inflammatory immune-mediated polyradiculoneuropathy characterized by tingling,progressive weakness,autonomic dysfunction,and pain.Immune injury specifically takes place at the myelin sheath and related Schwann-cell components in acute inflammatory demyelinating polyneuropathy,whereas in acute motor axonal neuropathy membranes on the nerve axon(the axolemma)are the primary target for immune-related injury.Outbreaks of GBS have been reported,most frequently related to Campylobacter jejuni infection,however,other agents such as Zika Virus have been strongly associated.Patients with GBS related to infections frequently produce antibodies against human peripheral nerve gangliosides.In contrast,TM is an inflammatory disorder characterized by acute or subacute motor,sensory,and autonomic spinal cord dysfunction.There is interruption of ascending and descending neuroanatomical pathways on the transverse plane of the spinal cord similar to GBS.It has been suggested to be triggered by infectious agents and molecular mimicry.In this review,we will focus on the putative role of infectious agents as triggering factors of GBS and TM. | Yhojan Rodríguez Manuel Rojas Yovana Pacheco Yeny Acosta-Ampudia Carolina Ramírez-Santana Diana M Monsalve M Eric Gershwin Juan-Manuel Anaya | 2018 | Cellular & Molecular Immunology2018，15，6： | 7 |
| 5 | Endoscopic ultrasound-guided vs endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis显示文摘BACKGROUND For palliation of malignant biliary obstruction(MBO), the gold-standard method of biliary drainage is endoscopic retrograde cholangiopancreatography(ERCP)with the placement of metallic stents. Endoscopic ultrasound(EUS)-guided drainage is an alternative that is typically reserved for cases of ERCP failure.Recently, however, there have been robust randomized clinical trials(RCTs)comparing EUS-guided drainage and ERCP as primary approaches to MBO.AIM To compare EUS guidance and ERCP in terms of their effectiveness and safety in palliative biliary drainage for MBO.METHODS This was a systematic review and meta-analysis, in which we searched the MEDLINE, Excerpta Medica, and Cochrane Central Register of Controlled Trials databases. Only RCTs comparing EUS and ERCP for primary drainage of MBO were eligible. All of the studies selected provided data regarding the rates of technical and clinical success, as well as the duration of the procedure, adverse events, and stent patency. We assessed the risk of biases using the Jadad score and the quality of evidence using the Grading of Recommendations Assessment,Development and Evaluation criteria.RESULTS The database searches yielded 5920 records, from which we selected 3 RCTs involving a total of 222 patients(112 submitted to EUS and 110 submitted to ERCP). In the EUS and ERCP groups, the rate of technical success was 91.96%n and 91.81%, respectively, with a risk difference(RD) of 0.00%(95%CI:-0.07, 0.07;P = 0.97; I^2 = 0%). The clinical success was 84.81% and 85.53% in the EUS and ERCP groups, respectively, with an RD of-0.01%(95%CI:-0.12, 0.10; P = 0.90; I^2 =0%). The mean difference(MD) for the duration of the procedure was-0.12%(95%CI:-8.20, 7.97; P = 0.98; I^2 = 84%). In the EUS and ERCP groups, there were14 and 25 adverse events, respectively, with an RD of-0.06%(95%CI:-0.23, 0.12; P= 0.54; I^2 = 77%). The MD for stent patency was 9.32%(95%CI:-4.53, 23.18; P =0.19; I^2 = 44%). The stent dysfunction rate was significantly lower in the EUS t group(MD =-0.22%; 95 CI:-0.35,-0.08; P = 0.001; I^2 = 0%).CONCLUSION EUS represents an interesting alternative to ERCP for MBO drainage,demonstrating lower stent dysfunction rates compared with ERCP. Technical and clinical success, duration, adverse events and patency rates were similar. | Fernanda P Logiudice Wanderlei M Bernardo Facundo Galetti Vitor M Sagae Carolina O Matsubayashi Antonio C Madruga Neto Vitor O Brunaldi Diogo T H de Moura Tomazo Franzini Spencer Cheng Sergio E Matuguma Eduardo G H de Moura | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，4： | 6 |
| 6 | Pathological features and diagnosis of intraductal papillary mucinous neoplasm of the pancreas显示文摘Intraductal papillary mucinous neoplasm(IPMN) of the pancreas is a noninvasive epithelial neoplasm of mucinproducing cells arising in the main duct(MD) and/or branch ducts(BD) of the pancreas.Involved ducts are dilated and filled with neoplastic papillae and mucus in variable intensity.IPMN lacks ovarian-type stroma,unlike mucinous cystic neoplasm,and is defined as a grossly visible entity(≥ 5 mm),unlike pancreatic intraepithelial neoplasm.With the use of high-resolution imaging techniques,very small IPMNs are increasingly being identified.Most IPMNs are solitary and located in the pancreatic head,although 20%-40% are multifocal.Macroscopic classification in MD type,BD type and mixed or combined type reflects biological differences with important prognostic and preoperative clinical management implications.Based on cytoarchitectural atypia,IPMN is classified into low-grade,intermediategrade and high-grade dysplasia.Based on histological features and mucin(MUC) immunophenotype,IPMNs are classified into gastric,intestinal,pancreatobiliary and oncocytic types.These different phenotypes can be observed together,with the IPMN classified according to the predominant type.Two pathways have been suggested:gastric phenotype corresponds to less aggressive uncommitted cells(MUC1-,MUC2-,MUC5 AC +,MUC6 +) with the capacity to evolve to intestinal phenotype(intestinal pathway)(MUC1-,MUC2 +,MUC5 AC +,MUC6- or weak +) or pancreatobiliary /oncocytic phenotypes(pyloropancreatic pathway)(MUC1 +,MUC 2-,MUC5 AC +,MUC 6 +) becoming more aggressive.Prognosis of IPMN is excellent but critically worsens when invasive carcinoma arises(about 40% of IPMNs),except in some cases of minimal invasion.The clinical challenge is to establish which IPMNs should be removed because of their higher risk of developing invasive cancer.Once resected,they must be extensively sampled or,much better,submitted in its entirety for microscopic study to completely rule out associated invasive carcinoma. | Víctor M Castellano-Megías Carolina Ibarrola-de Andrés Guadalupe López-Alonso Francisco Colina-Ruizdelgado | 2014 | World Journal of Gastrointestinal Oncology2014，6，9： | 4 |
| 7 | Quality 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 | 2019 | World Journal of Gastroenterology2019，25，38： | 2 |
| 8 | Six-minute walking test performance is associated with survival in cirrhotic patients显示文摘BACKGROUND Patients with cirrhosis are at risk of cirrhotic cardiomyopathy,with resulting cardiac dysfunction and exercise limitations.Six minute walking test(6MWT)assesses functional status and predicts morbidity and mortality in cardiopulmonary diseases.AIM To determine if it associates with mortality by analyzing 6MWT performance in patients with liver cirrhosis.METHODS A cohort of 106 cirrhotic patients was evaluated in the outpatient setting with echocardiogram and 6MWT and follow up for one year to document hepatic decompensation and mortality.The distance in meters was recorded at the end of 6 min(6MWD).RESULTS This cohort had a mean age of 51 years and 56%male;patients were staged as Child A in 21.7%,B 66%and C 12.3%.Walk distance inversely correlated with Child scores,and was significantly reduced as Child stages progresses.Patients who died(10.4%)showed shorter mean 6MWD(P=0.006).Low 6MWD was an independent predictor of mortality(P=0.01).CONCLUSION 6MWT is a noninvasive inexpensive test whose result is related to Child scores and mortality.It is useful to identify patients with liver cirrhosis at high risk of mortality for closer monitoring and potential early intervention. | Carolina Frade M G Pimentel Ana Cristina de Castro Amaral Adriano Miziara Gonzalez Michelle Lai Danielde Oliveira Mota Maria Lucia Gomes Ferraz Wilson Mathias Junior Mario Kondo | 2021 | World Journal of Hepatology2021，13，11： | 2 |
| 9 | COVID-19 and neurologic manifestations:a synthesis from the child neurologist’s corner显示文摘Background Since December 2019,the SARS-CoV-2 virus has been a global health issue.The main clinical presentation of this virus is a flu-like disease;however,patients with diverse neurologic manifestations have also been reported.In this review,we attempt to summarize,discuss and update the knowledge of the neurologic manifestations in the pediatric population affected by SARS-CoV-2 infection and the pandemic’s effects in children with neurologic diseases.Data sources This review analyzes studies found on the PubMed database using the following keywords:Neurologic manifestations COVID-19,Neurological COVID-19,coronavirus,SARS-CoV-2,pediatric COVID-19,COVID-19 in children,MIS-C,Pediatric Inflammatory Multisystem Syndrome,Guillain BarréSyndrome,Stroke,ADEM,and Anti-NMDA encephalitis.All studies cited were published between 2004 and 2022,and represent the most relevant articles in the field.The World Health Organization COVID-19 online dashboard was assessed to obtain updated epidemiological data.Results The most common neurologic symptoms in the pediatric population are headache,seizures,encephalopathy,and muscle weakness.These can be present during COVID-19 or weeks after recovering from it.Children who presented with multi-system inflammatory syndrome had a higher incidence of neurologic manifestations,which conferred a greater risk of morbidity and mortality.Several neuro-pathophysiological mechanisms have been proposed,including direct virus invasion,hyper-inflammatory reactions,multi-systemic failure,prothrombotic states,and immune-mediated processes.On the other hand,the COVID-19 pandemic has affected patients with neurologic diseases,making it challenging to access controls,treatment,and therapies.Conclusions Various neurologic manifestations have been associated with children’s SARS-CoV-2 infection.It is important to identify and give them proper and opportune treatment because they can be potentially grave and life-threatening;some can lead to long-lasting sequelae.Different neuro-pathophysiological mechanisms have been proposed,however,a causal relationship between SARS-CoV-2 infection and neurologic manifestations remains to be proven.Patients with neurologic diseases are especially affected by COVID-19,not only by the disease itself but also by its complications and pandemic management measures. | Carolina Valderas Gastón Méndez Alejandra Echeverría Nelson Suarez Katherin Julio Francisca Sandoval | 2022 | World Journal of Pediatrics2022，18，6： | 2 |
| 10 | Human enamel thickness and ENAM polymorphism显示文摘The tooth enamel development gene, enamelin(ENAM), showed evidence of positive selection during a genome-wide scan of human and primate DNA for signs of adaptive evolution. The current study examined the hypothesis that a single-nucleotide polymorphism(SNP) C14625T(rs7671281) in the ENAM gene identified in the genome-wide scan is associated with a change in enamel phenotype. African Americans were selected as the target population, as they have been reported to have a target SNP frequency of approximately 50%, whereas non-Africans are predicted to have a 96% SNP frequency. Digital radiographs and DNA samples from 244 teeth in 133 subjects were analysed, and enamel thickness was assessed in relation to SNP status,controlling for age, sex, tooth number and crown length. Crown length was found to increase with molar number, and females were found to have thicker enamel. Teeth with larger crowns also had thicker enamel, and older subjects had thinner enamel.Linear regression and generalized estimating equations were used to investigate the relationship between enamel thickness of the mandibular molars and ENAM SNP status; enamel in subjects with the derived allele was significantly thinner(P = 0.040)when the results were controlled for sex, age, tooth number and crown length. The derived allele demonstrated a recessive effect on the phenotype. The data indicate that thinner dental enamel is associated with the derived ENAM genotype. This is the first direct evidence of a dental gene implicated in human adaptive evolution as having a phenotypic effect on an oral structure. | Diane M Daubert Joanna L Kelley Yuriy G Udod Carolina Habor Chris G Kleist Ilona K Furman Igor N Tikonov Willie J Swanson Frank A Roberts | 2016 | International Journal of Oral Science2016，8，2： | 2 |
| 11 | Non-pharmacological management of pediatric functional abdominal pain disorders:Current evidence and future perspectives显示文摘Functional abdominal pain disorders(FAPDs) are an important and prevalent cause of functional gastrointestinal disorders among children, encompassing the diagnoses of functional dyspepsia, irritable bowel syndrome, abdominal migraine, and the one not previously present in Rome Ⅲ, functional abdominal pain not otherwise specified. In the absence of sufficiently effective and safe pharmacological treatments for this public problem, non-pharmacological therapies emerge as a viable means of treating these patients, avoiding not only possible side effects, but also unnecessary prescription, since many of the pharmacological treatments prescribed do not have good efficacy when compared to placebo. Thus, the present study provides a review of current and relevant evidence on non-pharmacological management of FAPDs, covering the most commonly indicated treatments, from cognitive behavioral therapy to meditation, acupuncture, yoga, massage, spinal manipulation, moxibustion, and physical activities. In addition, this article also analyzes the quality of publications in the area, assessing whether it is possible to state if non-pharmacological therapies are viable, safe, and sufficiently well-based for an appropriate and effective prescription of these treatments. Finally, it is possible to observe an increase not only in the number of publications on the non-pharmacological treatments for FAPDs in recent years, but also an increase in the quality of these publications. Finally, the sample selection of satisfactory age groups in these studies enables the formulation of specific guidelines for this age group, thus avoiding the need for adaptation of prescriptions initially made for adults, but for children use. | Maria Luísa Cordeiro Santos Ronaldo Teixeira da Silva Júnior Breno Bittencourt de Brito Filipe Antônio França da Silva Hanna Santos Marques Vinícius Lima de SouzaGonçalves Talita Costa dos Santos Carolina Ladeia Cirne Natália Oliveira e Silva Márcio Vasconcelos Oliveira Fabrício Freire de Melo | 2022 | World Journal of Clinical Pediatrics2022，11，2： | 2 |
