1Relationship 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
2Heat Transfer in Steelmaking Ladle显示文摘The heat transfer in a steelmaking ladle was studied. The evaluation of heat transfer of the steel was performed by measuring steel temperature in points including all refining steel process. In the ladle, the temperatures in the refractories and the shell were also measured. To evaluate the thermal profile between the hot and cold faces of the ladle in the slag line position, an experiment which shows the importance of thermal contact resistance was carried out. Higher heat losses in the tapping and the vacuum were verified. The temperature measurements of the ladle indicate distinct thermal profiles in each stage of steel refining. Moreover, as each stage of the process depends on the previous one, the complexity of the ladle thermal control is incremental. So a complete model of heat losses in the ladle is complex.André Zimmer lvaro Niedersberg Correia Lima Rafael Mello Trommer Saulo Roca Bragana Carlos Pérez Bergmann 2008Journal of Iron and Steel Research(International)2008,15,3:4
3Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context.Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,2:3
4Embryonal rhabdomyosarcoma in the maxillary sinus with orbital involvement in a pediatric patient:Case report显示文摘This report presents a case of embryonal rhabdomyosarcoma(e RMS) located in the left maxillary sinus and invading the orbital cavity in a ten-year-old male patient who was treated at a referral hospital.The images provided from the computed tomography showed a heterogeneous mass with soft-tissue density,occupying part of the left half of the face inside the maxillary sinus,and infiltrating and destroying the bone structure of the maxillary sinus,left orbit,ethmoidal cells,nasal cavity,and sphenoid sinus.An analysis of the histological sections revealed an undifferentiated malignant neoplasm infiltrating the skeletal muscle tissue.The immunohistochemical analysis was positive for the antigens:MyoD 1,myogenin,desmin,and Ki67(100% positivity in neoplastic cells),allowing the identification of the tumour as an eR MS.The treatment protocol included initial chemotherapy followed by radiotherapy and finally surgery.The total time of the treatment was nine months,and in 18-mo of follow-up period did not show no local recurrences and a lack of visual impairment.Ana Carolina Rodrigues de Melo Tácio Candeia Lyra Isabella Lima Arrais Ribeiro Alexandre Rolim da Paz Paulo Rogério Ferreti Bonan Ricardo Dias de Castro Ana Maria Gondim Valen?a 2017World Journal of Clinical Cases2017,5,12:3

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
7早发性高血压患者中年时即出现高血压终末靶器官损害显示文摘早发高血压会增加社区心血管死亡的风险。早发高血压是否在中年时就可促发终末靶器官损害(target end-organ damage,TOD)的进展,目前仍不清楚。研究者纳入中青年人冠状动脉危险因素研究(coronary artery risk development in young adults,CARDIA)参与者2680例[平均年龄(50±4)岁,57%为女性],他们在1985-2011年间接受了多达8次系列血压测量(基线年龄范围18-30岁),并且在2010-2011年进行了左心室肥厚、冠状动脉钙化、白蛋白尿和舒张功能障碍的评估。刘青(译) 叶鹏(审校) Suvila K McCabe EL Lehtonen A Ebinger JE Lima JAC Cheng S Niiranen TJ 2019中华高血压杂志2019,27,10:2
8Helicobacter pylori infection:How does age influence the inflammatory pattern?显示文摘The inflammatory pattern during Helicobacter pylori(H.pylori)infection is changeable and complex.During childhood,it is possible to observe a predominantly regulatory response,evidenced by high concentrations of key cytokines for the maintenance of Treg responses such as TGF-β1 and IL-10,in addition to high expression of the transcription factor FOXP3.On the other hand,there is a predominance of cytokines associated with the Th1 and Th17 responses among H.pylori-positive adults.In the last few years,the participation of the Th17 response in the gastric inflammation against H.pylori infection has been highlighted due to the high levels of TGF-β1 and IL-17 found in this infectious scenario,and growing evidence has supported a close relationship between this immune response profile and unfavorable outcomes related to the infection.Moreover,this cytokine profile might play a pivotal role in the effectiveness of anti-H.pylori vaccines.It is evident that age is one of the main factors influencing the gastric inflammatory pattern during the infection with H.pylori,and understanding the immune response against the bacterium can assist in the development of alternative prophylactic and therapeutic strategies against the infection as well as in the comprehension of the pathogenesis of the outcomes related to that microorganism.Glauber Rocha Lima Araújo Hanna Santos Marques Maria Luísa Cordeiro Santos Filipe Antônio França daSilva Breno Bittencourt da Brito Gabriel Lima Correa Santos Fabrício Freire de Melo 2022World Journal of Gastroenterology2022,28,4:2
9Personalized medicine in gastric cancer:Where are we andwhere are we going?显示文摘Despite improvements in adjuvant therapies for gastric cancer in recent years, the disease is characterized by high recurrence rates and a dismal prognosis. The major improvement in the treatment of recurrent or metastatic gastric cancer in recent years has been the incorporation of trastuzumab, a monoclonal antibody that inhibits human epidermal growth factor receptor 2(HER2) heterodimerization, after the demonstrated predictive value of the overexpression and/or amplification of this receptor. Beyond HER2, other genetic abnormalities have been identified, and these mutations may be targetable by tyrosine kinase inhibitors or monoclonal antibodies. The demonstration of four distinct molecular subtypes of gastric cancer by the Cancer Genome Atlas study highlight the enormous heterogeneity of the disease and its complex interplay between genetic and epigenetic alterations and provide a roadmap to implement genome-guided personalized therapy in gastric cancer. In the present review, we aim to discuss, from a clinical point of view, the genomic landscape of gastric cancer described in recent studies, the therapeutic insights derived from these findings, and the clinical trials that have been conducted and those in progress that take into account tailored therapies for gastric cancer.Alexandre A Jácome Anelisa K Coutinho Enaldo M Lima Aline C Andrade JoséSebastião dos Santos 2016World Journal of Gastroenterology2016,22,3:2

11Non-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 2022World Journal of Clinical Pediatrics2022,11,2:2
12由磁共振成像评估的主动脉弓脉搏波传导速度是心血管事件的预测因子:多种族动脉粥样硬化研究显示文摘通过磁共振成像评估的主动脉弓脉搏波传导速度(pulse wave velocity,PWV)对心血管病事件的预测价值尚未完全确定。为了评估多种族动脉粥样硬化研究(multi-ethnic study of atherosclerosis,MESA)受试者中主动脉弓PWV与心血管病的关系,Ohyama等纳入3527例MESA受试者[基线时平均年龄为(62±10)岁,47%为男性],刘莉 叶鹏 Ohyama Y Ambale-Venkatesh B Noda C Kim JY Tanami Y Teixido-Tura G Chugh AR Redheuil A Liu CY Wu CO Hundley WG Bluemke DA Guallar E Lima JAC 2017中华高血压杂志2017,25,8:2
