| 1 | Bile leakage after loop closure vs clip closure of the cystic duct during laparoscopic cholecystectomy:A retrospective analysis of a prospective cohort显示文摘BACKGROUND Laparoscopic cholecystectomy(LC)is one of the most frequently performed surgical procedures.Cystic stump leakage is an underestimated,potentially life threatening complication that occurs in 1%-6%of the patients.With a secure cystic duct occlusion technique during LC,bile leakage becomes a preventable complication.AIM To investigate the effect of polydioxanone(PDS)loop closure of the cystic duct on bile leakage rate in LC patients.METHODS In this retrospective analysis of a prospective cohort,the effect of PDS loop closure of the cystic duct on bile leakage complication was compared to patients with conventional clip closure.Logistic regression analysis was used to develop a risk score to identify bile leakage risk.Leakage rate was assessed for categories of patients with increasing levels of bile leakage risk.RESULTS Of the 4359 patients who underwent LC,136(3%)underwent cystic duct closure by a PDS loop.Preoperatively,loop closure patients had significantly more complicated biliary disease compared to the clipped closure patients.In the loop closure cohort,zero(0%)bile leakage occurred compared to 59 of 4223(1.4%)clip closure patients.For patients at increased bile leakage risk(risk score≥1)rates were 1.6%and up to 13%(4/30)for clip closure patients with a risk score≥4.This risk increase paralleled a stepwise increase of actual bile leakage complication for clip closure patients,which was not observed for loop closure patients.CONCLUSION Cystic duct closure with a PDS loop during LC may reduce bile leakage in patients at increased risk for bile leakage. | Sandra C Donkervoort Lea M Dijksman Aafke H van Dijk Emile A Clous Marja A Boermeester Bert van Ramshorst Djamila Boerma | 2020 | World Journal of Gastrointestinal Surgery2020，12，1： | 4 |
| 2 | Comprehensive evaluation of the metabolic effects of insect meal from Tenebrio molitor L.in growing pigs by transcriptomics, metabolomics and lipidomics显示文摘Background:The hypothesis was tested that insect meal(IM)as protein source influences intermediary metabolism of growing pigs.To test this,30 male,5-week-old crossbred pigs were randomly assigned to 3 groups of 10 pigs each with similar body weights(BW)and fed isonitrogenous diets either without(CON)or with 5%IM(IM5)or 10%IM(IM10)from Tenebrio molitor L.for 4 weeks and key metabolic tissues(liver,muscle,plasma)were analyzed using omics-techniques.Results:Most performance parameters did not differ across the groups,whereas ileal digestibilities of most amino acids were 6.7 to 15.6%-units lower in IM10 than in CON(P<0.05).Transcriptomics of liver and skeletal muscle revealed a total of 166 and 198,respectively,transcripts differentially expressed between IM10 and CON(P<0.05).Plasma metabolomics revealed higher concentrations of alanine,citrulline,glutamate,proline,serine,tyrosine and valine and a lower concentration of asparagine in IM10 than in CON(P<0.05).Only one out of fourteen quantifiable amino acid metabolites,namely methionine sulfoxide(MetS),in plasma was elevated by 45%and 71%in IM5 and IM10,respectively,compared to CON(P<0.05).Plasma concentrations of both,major carnitine/acylcarnitine species and bile acids were not different across groups.Lipidomics of liver and plasma demonstrated no differences in the concentrations of triacylglycerols,cholesterol and the main phospholipids,lysophospholipids and sphingolipids between groups.The percentages of all individual phosphatidylcholine(PC)and phosphatidylethanolamine(PE)species in the liver showed no differences between groups,except those with 6 double bonds(PC 38:6,PC 40:6,PE 38:6,PE 40:6),which were markedly lower in IM10 than in CON(P<0.05).In line with this,the percentage of C22:6n-3 in hepatic total lipids was lower in IM10 than in the other groups(P<0.05).Conclusions:Comprehensive analyzes of the transcriptome,lipidome and metabolome of key metabolic tissues indicate that partial or complete replacement of a conventional protein source by IM in the diet has only a weak impact on the intermediary metabolism of growing pigs.Thus,it is concluded that IM from Tenebrio molitor L.can be used as a dietary source of protein in pigs without causing adverse effects on metabolism. | Sandra Meyer Denise K.Gessner Maria S.Braune Theresa Friedhoff Erika Most Marcus Höring Gerhard Liebisch Holger Zorn Klaus Eder Robert Ringseis | 2020 | Journal of Animal Science and Biotechnology2020，11，2： | 4 |
| 3 | Gastro-duodenal disease in Africa: Literature review and clinical data from Accra, Ghana显示文摘Gastroduodenal disease(GDD)was initially thought to be uncommon in Africa.Amongst others,lack of access to optimal health infrastructure and suspicion of conventional medicine resulted in the reported prevalence of GDD being significantly lower than that in other areas of the world.Following the increasing availability of flexible upper gastro-intestinal endoscopy,it has now become apparent that GDD,especially peptic ulcer disease(PUD),is prevalent across the continent of Africa.Recognised risk factors for gastric cancer(GCA)include Helicobater pylori(H.pylori),diet,Epstein-Barr virus infection and industrial chemical exposure,while those for PUD are H.pylori,non-steroidal antiinflammatory drug(NSAID)-use,smoking and alcohol consumption.Of these,H.pylori is generally accepted to be causally related to the development of atrophic gastritis(AG),intestinal metaplasia(IM),PUD and distal GCA.Here,we perform a systematic review of the patterns of GDD across Africa obtained with endoscopy,and complement the analysis with new data obtained on premalignant gastric his-topathological lesions in Accra,Ghana which was compared with previous data from Maputo,Mozambique.As there is a general lack of structured cohort studies in Africa,we also considered endoscopy-based hospital or tertiary centre studies of symptomatic individuals.In Africa,there is considerable heterogeneity in the prevalence of PUD with no clear geographical patterns.Furthermore,there are differences in PUD within-country despite universally endemic H.pylori infection.PUD is not uncommon in Africa.Most of the African tertiary-centre studies had higher prevalence of PUD when compared with similar studies in western countries.An additional intriguing observation is a recent,ongoing decline in PUD in some African countries where H.pylori infection is still high.One possible reason for the high,sustained prevalence of PUD may be the significant use of NSAIDs in local or over-the-counter preparations.The prevalence of AG and IM,were similar or modestly higher over rates in western countries but lower than those seen in Asia..In our new data,sampling of 136 patients in Accra detected evidence of pre-malignant lesions(AG and/or IM)in 20 individuals(14.7%).Likewise,the prevalence of pre-malignant lesions,in a sample of 109 patients from Maputo,were 8.3%AG and 8.3%IM.While H.pylori is endemic in Africa,the observed prevalence for GCA is rather low.However,cancer data is drawn from country cancer registries that are not comprehensive due to considerable variation in the availability of efficient local cancer reporting systems,diagnostic health facilities and expertise.Validation of cases and their source as well as specificity of outcome definitions are not explicit in most studies further contributing to uncertainty about the precise incidence rates of GCA on the continent.We conclude that evidence is still lacking to support(or not)the African enigma theory due to inconsistencies in the data that indicate a particularly low incidence of GDD in African countries. | Timothy N Archampong Richard H Asmah Cathy J Richards Vicki J Martin Christopher D Bayliss Edília Botao Leonor David Sandra Beleza Carla Carrilho | 2019 | World Journal of Gastroenterology2019，25，26： | 3 |
| 4 | Systematic review of cystic duct closure techniques in relation to prevention of bile duct leakage after laparoscopic cholecystectomy显示文摘AIM To study the effect of different techniques of cystic duct closure on bile leakage after laparoscopic cholecystectomy(LC) for biliary disease.METHODS A systematic search of MEDLINE, Cochrane and EMBASE was performed. Rate of cystic duct leakage(CDL) was the primary outcome. Risk of bias was evaluated. Odds ratios were analyzed for comparison of techniques and pooled event rates for non-comparative analyses. Pooled event rates were compared for each of included techniques.RESULTS Out of 1491 articles, 38 studies were included. A total of 47491 patients were included, of which 38683(81.5%)underwent cystic duct closure with non-locking(metal)clips. All studies were of low-moderate methodological quality. Only two studies reported separate data on uncomplicated and complicated gallbladder disease. For overall CDL, an odds ratio of 0.4(95%CI: 0.06-2.48)was found for harmonic energy vs clip closure and an odds ratio of 0.17(95%CI: 0.03-0.93) for locking vs non-locking clips. Pooled CDL rate was around 1% for harmonic energy and metal clips, and 0% for locking clips and ligatures. CONCLUSION Based on available evidence it is not possible to either recommend or discourage any of the techniques for cystic duct closure during LC with respects to CDL,although data point out a slight preference for locking clips and ligatures vs other techniques. No separate recommendation can be made for complicated gallbladder disease. | Aafke H van Dijk Stijn van Roessel Philip R de Reuver Djamila Boerma Marja A Boermeester Sandra C Donkervoort | 2018 | World Journal of Gastrointestinal Surgery2018，10，6： | 3 |
| 5 | Indirect printing of hierarchical patient-specific scaffolds for meniscus tissue engineering显示文摘The complex meniscus tissue plays a critical role in the knee. The high susceptibility to injury has led to an intense pursuit for better tissue engineering regenerative strategies, where scaffolds play a major role. In this study, indirect printed hierarchical multilayered sca ffolds composed by a silk fibroin (SF) upper layer and an 80/20 (w/w) ratio of SF/ionic-doped β-tricalcium phosphate (TCP) bottom layer were developed. Furthermore, a comparative analysis between two types of sca ffolds pro- duced using di fferent SF concentrations, i.e., 8% (w/v) (Hi8) and 16% (w/v) (Hi16) was performed. In terms of architecture and morphology, the produced sca ffolds presented homogeneous porosity in both layers and no di fferences were observed when comparing both sca ffolds. A decrease in terms of mechanical performance of the sca ffolds was observed when SF concentration decreased from 16 to 8% (w/v). Hi16 revealed a static compressive modulus of 0.66 ± 0.05 MPa and dynamical mechanical properties ranging from 2.17 ± 0.25 to 3.19 ± 0.38 MPa. By its turn, Hi8 presented a compressive modulus of 0.27 ± 0.08 MPa and dynamical mechanical properties ranging from 1.03 ± 0.08 MPa to 1.56 ± 0.13 MPa. In vitro bioactivity studies showed formation of apatite crystals onto the surface of Hi8 and Hi16 bottom layers. Human meniscus cells (hMCs) and human primary osteoblasts were cultured separately onto the top layer (SF8 and SF16) and bottom layer (SF8/TCP and SF16/TCP) of the hierarchical sca ffolds Hi8 and Hi16, respectively. Both cell types showed good adhesion and proliferation as denoted by the live/dead staining, Alamar Blue assay and DNA quanti fication analysis. Subcutaneous implantation in mice revealed weak in flammation and sca ffold’s integrity. The hierarchical indirect printed SF sca ffolds can be promising candidate for meniscus TE sca ffolding applications due their suitable mechanical properties, good biological performance and possibility of being applied in a patient-speci fic approach. | Joao BCosta Joana Silva-Correia Sandra Pina Alain da Silva Morais Sílvia Vieira Hélder Pereira Joao Espregueira-Mendes Rui LReis Joaquim M.Oliveira | 2019 | Bio-Design and Manufacturing2019，2，4： | 2 |
