| 1 | Computed 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 Guimares Charles E Zurstrassen Rubens Chojniak | 2015 | World Journal of Gastroenterology2015,21,12: | 14 |
| 2 | Lymphocyte subsets in alcoholic liver disease显示文摘AIM:To compare lymphocyte subsets between healthy controls and alcoholics with liver disease.METHODS:The patient cohort for this study included individuals who were suspected to have alcoholic liver disease(ALD) and who had undergone liver biopsy(for disease grading and staging,doubts about diagnosis,or concurrent liver disease;n = 56).Normal controls included patients who were admitted for elective cholecystectomy due to non-complicated gallstones(n = 27).Formalin-fixed,paraffin-embedded liver biopsy specimens were sectioned and stained with hematoxylin and eosin and Perls' Prussian blue.The non-alcoholic steatohepatitis score was used to assess markers of ALD.Lymphocyte population subsets were determined by flow cytometry.T lymphocytes were identified(CD3+),and then further subdivided into CD4+ or CD8+ populations.B lymphocytes(CD19+) and natural killer(NK) cell numbers were also measured.In addition to assessing lymphocyte subpopulation differences between ALD patients and controls,we also compared subsets of alcoholic patients without cirrhosis or abstinent cirrhotic patients to normal controls.RESULTS:The patient cohort primarily consisted of older men.Active alcoholism was present in 66.1%.Reported average daily alcohol intake was 164.9 g and the average lifetime cumulative intake was 2211.6 kg.Cirrhosis was present in 39.3% of the patients and 66.1% had significant fibrosis(perisinusoidal and portal/periportal fibrosis,bridging fibrosis,or cirrhosis) in their liver samples.The average Mayo end-stage liver disease score was 7.6.No hereditary hemochromatosis genotypes were found.ALD patients(n = 56) presented with significant lymphopenia(1.5 × 109/L ± 0.5 × 109/L vs 2.1 × 109/L ± 0.5 × 109/L,P < 0.0001),due to a decrease in all lymphocyte subpopulations,except for NK lymphocytes:CD3+(1013.0 ± 406.2/mm3 vs 1523.0 ± 364.6/mm3,P < 0.0001),CD4+(713.5 ± 284.7/mm3 vs 992.4 ± 274.7/mm3,P < 0.0001),CD8+(262.3 ± 140.4/mm3 vs 478.9 ± 164.6/mm3,P < 0.0001),and CD19+(120.6 ± 76.1/mm3 vs 264.6 ± 88.0/mm3,P < 0.0001).CD8+ lymphocytes suffered the greatest reduction,as evidenced by an increase in the CD4+/CD8+ ratio(3.1 ± 1.3 vs 2.3 ± 0.9,P = 0.013).This ratio was associated with the stage of fibrosis on liver biopsy(rs = 0.342,P = 0.01) and with Child-Pugh score(rs = 0.482,P = 0.02).The number of CD8+ lymphocytes also had a positive association with serum ferritin levels(rs = 0.345,P = 0.009).Considering only patients with active alcoholism but not cirrhosis(n = 27),we found similar reductions in total lymphocyte counts(1.8 × 109/L ± 0.3 × 109/L vs 2.1 × 109/L ± 0.5 × 109/L,P = 0.018),and in populations of CD3+(1164.7 ± 376.6/mm3 vs 1523.0 ± 364.6/mm3,P = 0.001),CD4+(759.8 ± 265.0/mm3 vs 992.4 ± 274.7/mm3,P = 0.003),CD8+(330.9 ± 156.3/mm3 vs 478.9 ± 164.6/mm3,P = 0.002),and CD19+(108.8 ± 64.2/mm3 vs 264.6 ± 88.0/mm3,P < 0.0001).In these patients,the CD4+/CD8+ ratio and the number of NK lymphocytes was not significantly different,compared to controls.Comparing patients with liver cirrhosis but without active alcohol consumption(n = 11),we also found significant lymphopenia(1.3 × 109/L ± 0.6 × 109/L vs 2.1 × 109/L ± 0.5 × 109/L,P < 0.0001) and decreases in populations of CD3+(945.5 ± 547.4/mm3 vs 1523.0 ± 364.6/mm3,P = 0.003),CD4+(745.2 ± 389.0/mm3 vs 992.4 ± 274.7/mm3,P = 0.032),CD8+(233.9 ± 120.0/mm3 vs 478.9 ± 164.6/mm3,P < 0.0001),and CD19+(150.8 ± 76.1/mm3 vs 264.6 ± 88.0/mm3,P = 0.001).The NK lymphocyte count was not significantly different,but,in this group,there was a significant increase in the CD4+/CD8+ ratio(3.5 ± 1.3 vs 2.3 ± 0.9,P = 0.01).CONCLUSION:All patient subsets presented with decreased lymphocyte counts,but only patients with advanced fibrosis presented with a significant increase in the CD4+/CD8+ ratio. | Luís Costa Matos Paulo Batista Nuno Monteiro Joo Ribeiro Maria A Cipriano Pedro Henriques Fernando Giro Armando Carvalho | 2013 | World Journal of Hepatology2013,5,2: | 4 |
| 3 | 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 |
| 4 | Pentoxifylline 通过 TNF- 合成和 TGF-1 基因表示的下面规定改进肝新生显示文摘 AIM:To investigate the mechanism of pentoxifylline(PTX)improvement in liver regeneration.RESULTS:Rats were randomized into 4 groups:Control rats;Sham-sham-operation rats;Saline-70% hepatectomy plus saline solution;PTX-70%hepatectomy plus PTX.At 2 and 6 h after hepatectomy,aspartate aminotransferase,alanine aminotransferase,tumor necrosis factor(TNF)-α and interleukin-6(IL-6)serum and hepatic tissue levels were determined.Tumor growth factor(TGF)-β1 gene expression in liver tissue was evaluated 24 h after hepatectomy by quantitative reverse transcriptase polymerase chain reaction analysis.Proliferation was analyzed by mitotic index and proliferating cell nuclear antigen(PCNA)staining 48 h after hepatectomy.RESULTS:TNF-α and IL-6 serum levels increased at 2 and 6 h after hepatectomy.At 2 h after hepatectomy serum PTX was reduced but not hepatic levels of TNF-α and IL-6.A decrease in liver TGF-β1 gene expression and an increase in mitotic index and PCNA after hepatectomy were observed in the PTX treatment group in comparison to the saline group.CONCLUSION:PTX improves liver regeneration by a mechanism related to down regulation of TNF-α production and TGF-β1 gene expression. | Rodrigo Bronze Martino Ana Maria Mendona Coelho Márcia Saldanha Kubrusly Regina Leito Sandra Nassa Sampietre Marcel Cerqueira Cesar Machado Telesforo Bacchella Luiz Augusto Carneiro D’Albuquerque | 2012 | World Journal of Gastrointestinal Surgery2012,4,6: | 2 |

| 11 | Risk Factors for Preeclampsia:Results from a Cohort of Over 5000 Pregnancies in Spain显示文摘Objective:To determine the incidence of preeclampsia(PE)and preterm PE in Spain and to identify the risk factors for developing the disease.Methods:This is a multicenter prospective cohort study performed at six maternity units across Spain.Women with singleton pregnancies attending their first-trimester routine visit at the hospital were offered participation.Maternal and pregnancy characteristics,including mean arterial pressure,as well as ultrasound findings were recorded.Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for subsequent development of PE.Results:A total of 5868 pregnancies were recruited for this study,including 174(3.0%)cases of PE,47(0.8%)cases of preterm PE and 127(2.2%)cases of term PE.Median maternal age was 33.9 years(interquartile range:30.1 to 36.9)and median gestational age at the routine visit was 12.7 weeks(interquartile range:12.3 to 13.0).However,293(5.0%)of the women were on aspirin treatment during pregnancy,likely reducing the true incidence of the disease.As expected,increasing body mass index(P<0.001),uterine artery pulsatility index(P=0.011)and mean arterial pressure(P<0.001),assisted conception(P=0.013),previous personal(P<0.001)or family history of PE(P=0.024)and chronic hypertension(P=0.001)were identified as independent risk factors for developing subsequent PE during pregnancy.Screening for PE by maternal factors alone leads to a detection rate of 36.8%(64/174)at 10.0%(587/5868)screen positive rate.Conclusion:In Spain,3.0%of singleton pregnancies are complicated by PE and 0.8%require delivery before term due to its severity.Screening of PE by risk factors alone is only able to detect about 40%of total PE at 10%screen-positive rate. | Diana Cuenca Valeria Rolle Katy de Paco Matallana Nuria Valiño Rocio Revello Begoña Adiego Manel Mendoza Belen Santacruz Maria del Mar Gil | 2021 | Maternal-Fetal Medicine2021,3,2: | 1 |
