| 1 | Transfusion and coagulation management in liver transplantation显示文摘There is wide variation in the management of coagulation and blood transfusion practice in liver transplantation.The use of blood products intraoperatively is declining and transfusion free transplantations take place ever more frequently.Allogenic blood products have been shown to increase morbidity and mortality.Primary haemostasis,coagulation and fibrinolysis are altered by liver disease.This,combined with intraoperative disturbances of coagulation,increases the risk of bleeding.Meanwhile,the rebalancing of coagulation homeostasis can put patients at risk of hypercoagulability and thrombosis.The application of the principles of patient blood management to transplantation can reduce the risk of transfusion.This includes:preoperative recognition and treatment of anaemia,reduction of perioperative blood loss and the use of restrictive haemoglobin based transfusion triggers.The use of point of care coagulation monitoring using whole blood viscoelastic testing provides a picture of the complete coagulation process by which to guide and direct coagulation management.Pharmacological methods to reduce blood loss include the use of anti-fibrinolytic drugs to reduce fibrinolysis,and rarely,the use of recombinant factorⅦa.Factor concentrates are increasingly used;fibrinogen concentrates to improve clot strength and stability,and prothrombin complex con-centrates to improve thrombin generation.Non-pharmacological methods to reduce blood loss include surgical utilisation of the piggyback technique and maintenance of a low central venous pressure.The use of intraoperative cell salvage and normovolaemic haemodilution reduces allogenic blood transfusion.Further research into methods of decreasing blood loss and alternatives to blood transfusion remains necessary to continue to improve outcomes after transplantation. | Ben Clevenger Susan V Mallett | 2014 | World Journal of Gastroenterology2014,20,20: | 25 |
| 2 | Bemisia tabaci Phylogenetic Groups in India and the Relative Transmission Efficacy of Tomato leaf curl Bangalore virus by an Indigenous and an Exotic Population显示文摘Bemisia tabaci adults from various host-plant species were collected from 31 regions across India.266 B.tabaci samples were first screened by RAPD-PCR to examine molecular variability and to select individuals with different fingerprints.Host-plant and region of collection were then used to select 25 individuals for PCR amplification and sequencing of their partial mitochondrial cytochrome oxidase subunit one(mtCOI)genes.Pairwise comparisons with mtCOI consensus sequences showed that the majority of these samples had <3.5% sequence divergence from groups currently termed Asia I,Asia II-5,Asia II-7,and Asia II-8.The biotype-B B.tabaci from India clustered into the Middle East-Asia Minor 1 group.A new group of B.tabaci from Coimbatore,collected from pumpkin,was related most closely to the Asia I group(6.2% sequence divergence from the consensus Asia I sequence).To increase our understanding of the epidemiology of tomato leaf curl disease(ToLCD)and the key B.tabaci genetic groups involved in virus spread,the indigenous Asia I and the exotic biotype-B population from South India were used to carry out transmission experiments using Tomato leaf curl Bangalore virus(ToLCBV).The acquisition access periods(AAP),inoculation access periods(IAP),latent periods(LP),and ToLCBV transmission efficiencies of the two populations were compared and the biotype-B had the more efficient transmission characteristics.These results are discussed in relation to recent changes in the epidemiology of tomato leaf curl disease in South India. | R V Chowda-Reddy M Kirankumar Susan E Seal V Muniyappa Girish B Valand M R Govindappa John Colvin | 2012 | Journal of Integrative Agriculture2012,11,2: | 8 |
| 3 | Cirrhotic cardiomyopathy: Implications for the perioperative management of liver transplant patients显示文摘Cirrhotic cardiomyopathy is a disease that has only recently been recognised as a definitive clinical entity. In the setting of liver cirrhosis, it is characterized by a blunted inotropic and chronotropic response t o s t r e s s, i m p a i r e d d i a s t o l i c r e l a x a t i o n o f t h e myocardium and prolongation of the QT interval in the absence of other known cardiac disease. A key pathological feature is the persistent over-activation of the sympathetic nervous system in cirrhosis, which leads to down-regulation and dysfunction of theβ-adrenergic receptor. Diagnosis can be made using a combination of echocardiography(resting and stress), tissue Doppler imaging, cardiac magnetic resonance imaging, 12-lead electrocardiogram and measurement of biomarkers. There are significant implications of cirrhotic cardiomyopathy in a number of clinical situations in which there is an increased physiological demand, which can lead to acute cardiac decompensation and heart failure. Prior to transplantation there is an increased risk of hepatorenal syndrome, cardiac failure following transjugular intrahepatic portosystemic shunt insertion and increased risk of arrhythmias during acute gastrointestinal bleeding. Liver transplantation presents the greatest physiological challenge with a further risk of acute cardiac decompensation. Peri-operative management should involve appropriate choice of graft and minimization of large fluctuations in preload and afterload. The avoidance of cardiac failure during this period has important prognostic implications, as there is evidence to suggest a long-term resolution of the abnormalities in cirrhotic cardiomyopathy. | Suehana Rahman Susan V Mallett | 2015 | World Journal of Hepatology2015,7,3: | 8 |
| 4 | Early acute kidney injury after liver transplantation: Predisposing factors and clinical implications显示文摘AIM To investigate the additional clinical impact of hepatic ischaemia reperfusion injury(HIRI) on patients sustaining acute kidney injury(AKI) following liver transplantation.METHODS This was a single-centre retrospective study of consecutive adult patients undergoing orthotopic liver transplantation(OLT) between January 2013 and June 2014. Early AKI was identified by measuring serum creatinine at 24 h post OLT(> 1.5 × baseline) or by the use of continuous veno-venous haemofiltration(CVVHF) during the early post-operative period. Patients with and without AKI were compared to identify risk factors associated with this complication. Peak serum aspartate aminotransferase(AST) within 24 h post-OLT was used as a surrogate marker for HIRI and severity was classified as minor(< 1000 IU/L), moderate(1000-5000 IU/L) or severe(> 5000 IU/L). The impact on time to extubation, intensive care length of stay, incidence of chronic renal failure and 90-d mortality were examined firstly for each of the two complications(AKI and HIRI) alone and then as a combined outcome. RESULTS Out of the 116 patients included in the study, 50% developed AKI, 24% required CVVHF and 70% sustainedmoderate or severe HIRI. Median peak AST levels were 1248 IU/L and 2059 IU/L in the No AKI and AKI groups respectively(P = 0.0003). Furthermore, peak serum AST was the only consistent predictor of AKI on multivariate analysis P = 0.02. AKI and HIRI were individually associated with a longer time to extubation, increased length of intensive care unit stay and reduced survival. However, the patients who sustained both AKI and moderate or severe HIRI had a longer median time to extubation(P < 0.001) and intensive care length of stay(P = 0.001) than those with either complication alone. Ninety-day survival in the group sustaining both AKI and moderate or severe HIRI was 89%, compared to 100% in the groups with either or neither complication(P = 0.049). CONCLUSION HIRI has an important role in the development of AKI post-OLT and has a negative impact on patient outcomes, especially when occurring alongside AKI. | Suehana Rahman Susan V Mallett Brian R Davidson | 2017 | World Journal of Hepatology2017,9,18: | 6 |
| 5 | Methods for the extraction and RNA profiling of exosomes显示文摘AIM:To develop protocols for isolation of exosomes and characterization of their RNA content.METHODS:Exosomes were extracted from He La cell culture media and human blood serum using the Total exosome isolation(from cell culture media)reagent,and Total exosome isolation(from serum)reagent respectively.Identity and purity of the exosomes was confirmed by Nanosight?analysis,electron microscopy,and Western blots for CD63 marker.Exosomal RNA cargo was recovered with the Total exosome RNA and protein isolation kit.Finally,RNA was profiled using Bioanalyzer and quantitative reverse transcriptionpolymerase chain reaction(q RT-PCR)methodology.RESULTS:Here we describe a novel approach for robust and scalable isolation of exosomes from cell culture media and serum,with subsequent isolation and analysis of RNA residing within these vesicles.The isolation procedure is completed in a fraction of the time,compared to the current standard protocols utilizing ultracentrifugation,and allows to recover fully intact exosomes in higher yields.Exosomes were found tocontain a very diverse RNA cargo,primarily short sequences 20-200 nt(such as mi RNA and fragments of m RNA),however longer RNA species were detected as well,including full-length 18S and 28S r RNA.CONCLUSION:We have successfully developed a set of reagents and a workflow allowing fast and efficient extraction of exosomes,followed by isolation of RNA and its analysis by q RT-PCR and other techniques. | Emily Zeringer Mu Li Tim Barta Jeoffrey Schageman Ketil Winther Pedersen Axl Neurauter Susan Magdaleno Robert Setterquist Alexander V Vlassov | 2013 | World Journal of Methodology2013,3,1: | 5 |

| 8 | Reducing transfusion requirements in liver transplantation显示文摘Liver transplantation(LT) was historically associated with massive blood loss and transfusion. Over the past two decades transfusion requirements have reduced dramatically and increasingly transfusionfree transplantation is a reality. Both bleeding and transfusion are associated with adverse outcomes in LT. Minimising bleeding and reducing unnecessary transfusions are therefore key goals in the perioperative period. As the understanding of the causes of bleeding has evolved so too have techniques to minimize or reduce the impact of blood loss. Surgical 'piggyback' techniques, anaesthetic low central venous pressure and haemodilution strategies and the use of autologous cell salvage, point of care monitoring and targeted correction of coagulopathy, particularly through use of factor concentrates, have all contributed to declining reliance on allogenic blood products. Pre-emptive management of preoperative anaemia and adoption of more restrictive transfusion thresholds is increasingly common as patient blood management(PBM) gains momentum. Despite progress, increasing use of marginal grafts and transplantation of sicker recipients will continue to present new challenges in bleeding and transfusion management. Variation in practice across different centres and within the literature demonstrates the current lack of clear transfusion guidance. In this article we summarise the causes and predictors of bleeding and present the evidence for a variety of PBM strategies in LT. | Ciara I Donohue Susan V Mallett | 2015 | World Journal of Transplantation2015,5,4: | 4 |
| 9 | Eosinophils and mast cells as therapeutic targets in pediatric functional dyspepsia显示文摘There is an increasing appreciation for the importance of inflammation as a pathophysiologic entity that contributes to functional gastrointestinal disorders including functional dyspepsia(FD).Importantly,inflammation may serve as a mediator between psychologic and physiologic functions.This manuscript reviews the literature implicating two inflammatory cell types,mast cells and eosinophils,in the generation of dyspeptic symptoms and explores their potential as targets for the treatment of FD.There are a number of inciting events which may initiate an inflammatory response,and the subsequent recruitment and activation of mast cells and eosinophils.These include internal triggers such as stress and anxiety,as well as external triggers such as microbes and allergens.Previous studies suggest that there may be efficacy in utilizing medications directed at mast cells and eosinophils.Evidence exists to suggest that combining 'anti-inflammatory' medications with other treatments targeting stress can improve the rate of symptom resolution in pediatric FD. | Craig A Friesen Jennifer V Schurman Jennifer M Colombo Susan M Abdel-Rahman | 2013 | World Journal of Gastrointestinal Pharmacology and Therapeutics2013,4,4: | 4 |

| 11 | Thrombocytopenia in cirrhosis:Impact of fibrinogen on bleeding risk显示文摘AIM To investigate the relationship between baseline platelet count,clauss fibrinogen,maximum amplitude(MA) on thromboelastography,and blood loss in orthotopic liver transplantation(OLT).METHODS A retrospective analysis of our OLT Database(2006-2015) was performed.Baseline haematological indices and intraoperative blood transfusion requirements,as a combination of cell salvage return and estimation of 300 mls/unit of allogenic blood,was noted as a surrogate for intraoperative bleeding.Two groups:Excessive transfusion(>1200 mL returned) and No excessive transfusion(<1200 m L returned) were analysed.All data analyses were conducted using IBM SPSS Statistics version 23.RESULTS Of 322 OLT patients,77 were excluded due to fulminant disease;redo transplant or baseline haemoglobin(Hb) of<80 g/L.One hundred and fourteen(46.3%) were classified into the excessive transfusion group,132(53.7%) in the no excessive transfusion group.Mean age and gender distribution were similar in both groups.Baseline Hb(P≤0.001),platelet count(P=0.005),clauss fibrinogen(P=0.004) and heparinase MA(P=0.001) were all statistically significantly different.Univariate logistic regression with a cut-off of platelets<50×10~9/L as the predictor and Haemorrhage as the outcome showed an odds ratio of 1.393(95%CI:0.758-2.563;P=0.286).Review of receiver operating characteristic curves showed an area under the curve(AUC) for platelet count of 0.604(95%CI:0.534-0.675;P=0.005) as compared with AUC for fibrinogen level,0.678(95%CI:0.612-0.744;P≤0.001).A multivariate logistic regression shows United Kingdom model for End Stage Liver Disease(P=0.006),Hb(P=0.022) and Fibrinogen(P=0.026) to be statistically significant,whereas Platelet count was not statistically significant.CONCLUSION Platelet count alone does not predict excessive transfusion.Additional investigations,e.g.,clauss fibrinogen and viscoelastic tests,provide more robust assessment of bleeding-risk in thrombocytopenia and cirrhosis. | Sonali V Thakrar Susan V Mallett | 2017 | World Journal of Hepatology2017,9,6: | 4 |
| 12 | Present state and future challenges in pediatric abdominal pain therapeutics research: Looking beyond the forest显示文摘At the present time, it is nearly impossible to treat pediatric functional gastrointestinal disorders associated with pain in an evidence based fashion. This is due to the overall lack of controlled studies and, even more importantly, the complexity of the contributors to disease phenotype which are not controlled or accounted for in most therapeutic trials. In this manuscript, we review the challenges of defining entry criteria, controlling for the large number of biopsychosocial factors which may effect outcomes, and understanding pharmacokinetic and pharmacodynamic factors when designing therapeutic trials for abdominal pain in children. We also review the current state of pediatric abdominal pain therapeutics and discuss trial design considerations as we move forward. | Craig A Friesen Jennifer V Schurman Susan M Abdel-Rahman | 2015 | World Journal of Gastrointestinal Pharmacology and Therapeutics2015,6,4: | 3 |
| 13 | Next Generation Transcriptome Sequencing and Quantitative Real-Time PCR Technologies for Characterisation of the Bemisia tabaci Asia 1 mtCOI Phylogenetic Clade显示文摘A programme of functional genomics research is underway at the University of Greenwich,UK,to develop and apply genomics technologies to characterise an economically-important but under-researched Bemisia tabaci(Hemiptera:Aleyrodidae),the Asia 1 mtCOI phylogenetic group.A comparison of this putative species from India with other important B.tabaci populations and insect species may provide targets for the development of more effective whitefly control strategies.As a first step,next-generation sequencing(NGS)has been used to survey the transcriptome of adult female whitefly,with high quality RNA preparations being used to generate cDNA libraries for NGS using the Roche 454 Titanium DNA sequencing platform.Contig assemblies constructed from the resultant sequences(301 094 reads)using the software program CLC Genomics Workbench generated 3 821 core contigs.Comparison of a selection of these contigs with related sequences from other B.tabaci genetic groups has revealed good alignment for some genes(e.g.,HSP90)but misassemblies in other datasets(e.g.,the vitellogenin gene family),highlighting the need for manual curation as well as collaborative international efforts to obtain accurate assemblies from the existing next generation sequence datasets.Nevertheless,data emerging from the NGS has facilitated the development of accurate and reliable methods for analysing gene expression based on quantitative real-time RT-PCR,illustrating the power of this approach to enable rapid expression analyses in an organism for which a complete genome sequence is currently lacking. | Susan Seal Mitulkumar V Patel Carl Collins John Colvin David Bailey | 2012 | Journal of Integrative Agriculture2012,11,2: | 2 |
