1Performance of liver stiffness measurements by transient elastography in chronic hepatitis显示文摘AIM:To compare results of liver stiffness measurements by transient elastography(TE) obtained in our patients population with that used in a recently published meta-analysis.METHODS:This was a single center cross-sectional study.Consecutive patients with chronic viral hepatitis scheduled for liver biopsy at the outpatient ward of our Infectious Diseases Department were enrolled.TE was carried out by using FibroScan(Echosens,Paris,France).Liver biopsy was performed on the same day as TE,as day case procedure.Fibrosis was staged according to the Metavir scoring system.The diagnostic performance of TE was assessed by using receiver operating characteristic(ROC) curves and the area under the ROC curve analysis.RESULTS:Two hundred and fifty-two patients met the inclusion criteria.Six(2%) patients were excluded due to unreliable TE measurements.Thus,246(171 men and 75 women) patients were analyzed.One hundred and ninety-five(79.3%) patients had chronic hepatitis C,41(16.7%) had chronic hepatitis B,and 10(4.0%) were coinfected with human immunodeficiency virus.ROC curve analysis identified optimal cut-off value of TE as high as 6.9 kPa forF ≥ 2;7.9 kPa forF ≥ 3;9.6 kPa for F = 4 in all patients(n = 246),and as high as 6.9 kPa for F ≥ 2;7.3 kPa for F ≥ 3;9.3 kPa for F = 4 in patients with hepatitis C(n = 195).Cut-off values of TE obtained by maximizing only the specificity were as high as 6.9 kPa for F ≥ 2;9.6 kPa for F ≥ 3;12.2 kPa for F = 4 in all patients(n = 246),and as high as 7.0 kPa forF ≥ 2;9.3 kPa forF ≥ 3;12.3 kPa forF = 4 in patients with hepatitis C(n = 195).CONCLUSION:The cut-off values of TE obtained in this single center study are comparable to that obtained in a recently published meta-analysis that included up to 40 studies.Giovanna Ferraioli Carmine Tinelli Barbara Dal Bello Mabel Zicchetti Raffaella Lissandrin Gaetano Filice Carlo Filice Elisabetta Above Giorgio Barbarini Enrico Brunetti Willy Calderon Marta Di Gregorio Roberto Gulminetti Paolo Lanzarini Serena Ludovisi Laura Maiocchi Antonello Malfitano Giuseppe Michelone Lorenzo Minoli Mario Mondelli Stefano Novati Savino FA Patruno Alessandro Perretti Gianluigi Poma Paolo Sacchi Domenico Zanaboni Marco Zaramella 2013World Journal of Gastroenterology2013,19,1:18
2Minimally invasive treatment of pancreatic necrosis显示文摘AIM: To systematically review these minimally invasive approaches to infected pancreatic necrosis. METHODS: We used the MEDLINE database to investigate studies between 1996 and 2010 with greater than 10 patients that examined these techniques. Using a combination of Boolean operators, reports were retrieved addressing percutaneous therapy (341 studies), endoscopic necrosectomy (574 studies), laparoscopic necrosectomy via a transperitoneal approach (148 studies), and retroperitoneal necrosectomy (194 studies). Only cohorts with at least 10 or more patients were included. Non-English papers, letters, animal studies, duplicate series and reviews without original data were excluded, leaving a total of 27 studies for analysis. RESULTS: Twenty-seven studies with 947 patients total were examined (eight studies on percutaneous approach; ten studies on endoscopic necrosectomy; two studies on laparoscopic necrosectomy via a transperitoneal approach; five studies on retroperitoneal necrosectomy; and two studies on a combined percutaneous-retroperitoneal approach). Success rate, complications, mortality, and number of procedures were outcomes that were included in the review. We found that most published reports were retrospective in nature, and thus, susceptible to selection and publication bias. Few reports examined these techniques in a comparative, prospective manner. CONCLUSION: Each minimally invasive approach though was found to be safe and feasible in multiple reports. With these new techniques, treatment of infected pancreatic necrosis remains a challenge. We advocate a multidisciplinary approach to this complex problem with treatment individualized to each patient.Brian Bello Jeffrey B Matthews 2012World Journal of Gastroenterology2012,18,46:17

9High tacrolimus intra-patient variability is associated with graft rejection,and de novo donor-specific antibodies occurrence after liver transplantation显示文摘AIM To investigate the role of tacrolimus intra-patient variability(IPV) in adult liver-transplant recipients.METHODS We retrospectively assessed tacrolimus variability in a cohort of liver-transplant recipients and analyzed its effect on the occurrence of graft rejection and de novo donor-specific antibodies(dn DSAs), as well as graft survival during the first 2 years posttransplantation. Between 02/08 and 06/2015, 116 patients that received tacrolimus plus mycophenolate mofetil(with or without steroids) were included. RESULTS Twenty-two patients(18.5%) experienced at least one acute-rejection episode(BPAR). Predictive factors for a BPAR were a tacrolimus IPV of > 35% [OR = 3.07 95%CI(1.14-8.24), P = 0.03] or > 40% [OR = 4.16(1.38-12.50), P = 0.01), and a tacrolimus trough level of < 5 ng/mL [OR=3.68(1.3-10.4), P =0.014]. Thirteen patients(11.2%) developed at least one dn DSA during the follow-up. Tacrolimus IPV [coded as a continuous variable: OR = 1.1, 95%CI(1.0-1.12), P = 0.006] of > 35% [OR = 4.83, 95%CI(1.39-16.72), P = 0.01] and > 40% [OR = 9.73, 95%CI(2.65-35.76), P = 0.001] were identified as predictors to detect dn DSAs. IPV did not impact on patient-or graft-survival rates during the follow-up.

10Controlled attenuation parameter for evaluating liver steatosis in chronic viral hepatitis显示文摘AIM:To assess the performance of controlled attenuation parameter(CAP)in patients with chronic viral hepatitis.METHODS:CAP is a new technique that measures the attenuation in the liver of an ultrasound beam,which is directly related to lipid accumulation.Consecutive patients undergoing liver biopsy for chronic viral hepatitis were studied using the M probe of FibroScan device(Echosens,Paris,France).The device estimates liver st-eatosis in decibel per meter(dB/m).An expert operator performed all measurements.Steatosis was graded according to Kleiner’s classification.Pearson or Spearman rank coefficient was used to test correlation between two study variables.Linear regression was used for multivariate model to assess the association between CAP and other variables.Receiver operating characteristic curve analysis was performed to calculate area under the curve(AUROC)for S0 vs S1-S3 and S0-S1 vs S2-S3.RESULTS:115 subjects(85 males and 30 females)were prospectively studied.The mean values of CAP were 227.1±43.1 for S0;254.6±38.9 for S1;297.8±49.4 dB/m for S2-S3.In univariate analysis CAP showed a significant correlation with age,body mass index(BMI),degree of steatosis,and cholesterol.Multivariate regression analysis confirmed the correlation with the degree of steatosis[coefficient,1.2(0.60-1.83);P<10-5]and BMI[coefficient,4.1(0.5-7.8);P=0.03]but not with all other variables.Optimal cutoff values for S≥1 and S≥2 were 219 dB/m[AUROC,0.76(0.67-0.84);sensitivity,91.1%(78.8-97.5);specificity,51.6%(38.7-64.2);positive predictive value,56.9%(44.7-68.6);negative predictive value,89.2%(74.3-97.0);positive likelihood ratio,1.88(1.4-2.5);negative likelihood ratio,0.17(0.07-0.5)]and 296 dB/m[AUROC,0.82(0.74-0.89);sensitivity,60.0%(32.3-83.7);specificity,91.5%(83.9-96.3);positive predictive value,52.9%(27.8-77.0);negative predictive value,93.5%(86.3-97.6);positive likelihood ratio,7.05(3.2-15.4);negative likelihood ratio,0.44(0.2-0.8)],respectively.CONCLUSION:Controlled attenuation parameter could be a useful tool in the clinical management of patients with chronic viral hepatitis for detecting liver steatosis.Giovanna Ferraioli Carmine Tinelli Raffaella Lissandrin Mabel Zicchetti Barbara Dal Bello Gaetano Filice Carlo Filice 2014World Journal of Gastroenterology2014,20,21:7
11Impact of minimally invasive surgery on the treatment of benign esophageal disorders显示文摘Thanks to the development of minimally invasive surgery, the last 20 years have witnessed a change in the treatment algorithm of benign esophageal disorders. Today a laparoscopic operation is the treatment of choice for esophageal achalasia and for most patients with gastroesophageal reflux disease. Because the pathogenesis of achalasia is unknown, treatment is palliative and aims to improve esophageal emptying by decreasing the functional obstruction at the level of the gastro-esophageal junction. The refinement of minimally invasive techniques accompanied by large, multiple randomized control trials with long-term outcome has allowed the laparoscopic Heller myotomy and partial fundoplication to become the treatment of choice for achalasia compared to endoscopic procedures, including endoscopic botulinum toxin injection and pneumatic dilatation. Patients with suspected gastroesophageal reflux need to undergo a thorough preoperative workup. After establishing diagnosis, treatment for gastroesophageal reflux should be individualized to patient characteristics and a decision about an operation made jointly between surgeon and patient. The indications for surgery have changed in the last twenty years. In the past, surgery was often considered for patients who did not respond well to acid reducing medications. Today, the best candidate for surgery is the patient who has excellent control of symptoms with proton pump inhibitors. The minimally invasive approach to antireflux surgery has allowed surgeons to control reflux in a safe manner, with excellent long term outcomes. Like achalasia and gastroesophageal reflux, the treatment of patients with paraesophageal hernias has also seen a major evolution. The laparoscopic approach has been shown to be safe, and durable, with good relief of symptoms over the long-term. The most significant controversy with laparoscopic paraesophageal hernia repair is the optimal crural repair. This manuscript reviews the evolution of these techniques.Brian Bello Fernando A Herbella Marco E Allaix Marco G Patti 2012World Journal of Gastroenterology2012,18,46:6
12Protein Phosphorylation and Phosphoproteome:An Overview of Rice显示文摘Protein phosphorylation,one of the major post-translational modifications,plays a crucial role in cell signaling,DNA replication,gene expression and differentiation;and alters enzyme activity and other biological activities;and regulates cell proliferation and enlargement,phytohormone biosynthesis and signaling,plant disease resistance,and grain filling and quality during rice seed development.Research work on protein phosphorylation started in the 1950 s with the discovery of phosphorylase a and phosphorylase b which are phospho and dephospho forms of the same enzyme.Over the last decade,rice proteomics has accomplished tremendous progress in setting up techniques to proteome nearly all tissues,organs and organelles.The progress made in this field is evident in number of research works.However,research on rice protein phosphorylation is still at its infancy and there are still many unanswered questions.In this review,the general description of protein phosphorylation,including history,structure,frequency of occurrence and function,are discussed.This work also elucidates the different methods for identification,qualification and finally,the progress in rice phosphoproteome research and perspectives.Abolore Adijat AJADI Amara CISSE Shakeel AHMAD WANG Yifeng SHU Yazhou LI Shufan LIU Xixi Babatunde Kazeem BELLO Sani Muhammad TAJO TONG Xiaohong ZHANG Jian 2020Rice science2020,27,3:5

14Perception and Practice of Emergency Contraception among Female Undergraduates of the University of Ibadan, Nigeria显示文摘Objective To assess perception and level of proper utilization of emergency contraception (EC) among female undergraduates. Methods Cross-sectional questionnaire study was performed on 383 female under- graduates in Nigeria in June 2006. Data analysis was with χ-square test and logistic regressions (P<0.05). Results One hundred and five (48.2%) had been sexually exposed. Only 32 (30.5%) used regular contraception. Seventy-three (24.3%) female undergraduates were aware of EC. Only 29 (7.6%) had used EC before. Most would not use emergency contraceptive drugs in future due to lack of awareness (64.8%), and fear for future fertility and of drugs being injurious to health. Use of EC was associated with awareness of correct interval for use (OR=9.1; 95%CI: 2.1-39.9). Conclusion There is poor knowledge about EC and poor use, while significant need remains. Most knowledge was acquired from peers and inaccurate. Peer educators are important and professionals’ knowledge needs improvement.Folasade Adenike Bello Oladapo Olayemi Adeniran Olubukola Fawole Olayinka Oladunjoye Ogunbode Tolulope Sobukunola Olubukola Adeponle Adesina Christopher Aimakhu Michael Abiola Okunlola 2009Journal of Reproduction and Contraception2009,20,2:4

16Exercise manual for liver disease patients显示文摘AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation.METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index(BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease(MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure(MIP) and maximal expiratory pressure, spirometry, root mean square(RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference(P = 0.01) between the first(initial) and the third month(final) MIP in the control group and in the intervention group, but there was no difference(P = 0.45) between the groups.The RMS of the diaphragm was lower(P = 0.001) and the functional capacity was higher(P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group(P = 0.01) and the intervention group(P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group(P = 0.083) and intervention group(P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups(P = 0.21). In the intervention group, patients with ascites at the end of the time period had decreased scores on the social aspects SF-36 domain(P = 0.023) compared to those who had no ascites. CONCLUSION: The proposed exercises provide an increase in the inspiratory muscle strength and improve functional capacity, consequently bettering the quality of life of liver disease patients.Vivian Limongi Daniele Costa Dos Santos Aurea Maria de Oliveira da Silva Ilka de Fátima Santana Ferreira Boin Raquel Silveira Bello Stucchi 2016World Journal of Transplantation2016,6,2:3
17Phylogeography of SARS-CoV-2 pandemic in Spain:a story of multiple introductions,micro-geographic stratification,founder effects,and super-spreaders显示文摘Spain has been one of the main global pandemic epicenters for coronavirus disease 2019(COVID-19).Here,we analyzed>41000 genomes(including>26000 high-quality(HQ)genomes)downloaded from the GISAID repository,including 1245(922 HQ)sampled in Spain.The aim of this study was to investigate genome variation of novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and reconstruct phylogeographic and transmission patterns in Spain.Phylogeographic analysis suggested at least 34 independent introductions of SARS-CoV-2 to Spain at the beginning of the outbreak.Six lineages spread very successfully in the country,probably favored by super-spreaders,namely,A2 a4(7.8%),A2 a5(38.4%),A2 a10(2.8%),B3 a(30.1%),and B9(8.7%),which accounted for 87.9% of all genomes in the Spanish database.One distinct feature of the Spanish SARS-Cov-2 genomes was the higher frequency of B lineages(39.3%,mainly B3 a+B9)than found in any other European country.While B3 a,B9,(and an important sub-lineage of A2 a5,namely,A2 a5 c)most likely originated in Spain,the other three haplogroups were imported from other European locations.The B3 a strain may have originated in the Basque Country from a B3 ancestor of uncertain geographic origin,whereas B9 likely emerged in Madrid.The time of the most recent common ancestor(TMRCA)of SARS-CoV-2 suggested that the first coronavirus entered the country around 11 February 2020,as estimated from the TMRCA of B3 a,the first lineage detected in the country.Moreover,earlier claims that the D614 G mutation is associated to higher transmissibility is not consistent with the very high prevalence of COVID-19 in Spain when compared to other countries with lower disease incidence but much higher frequency of this mutation(56.4% in Spain vs.82.4% in rest of Europe).Instead,the data support a major role of genetic drift in modeling the micro-geographic stratification of virus strains across the country as well as the role of SARS-CoV-2 super-spreaders.Alberto Gomez-Carballa Xabier Bello Jacobo Pardo-Seco Maria Luisa Perez del Molino Federico Martinon-Torres Antonio Salas 2020Zoological Research2020,41,6:3
