1Synchrotron radiation investigations of the Sr_2MgSi_2O_7:Eu^(2+),R^(3+) persistent luminescence materials显示文摘The electronic and defect energy level structure of polycrystalline Sr2MgSi2O7:Eu2+,R3+ persistent luminescence materials were studied with thermoluminescence and different synchrotron radiation spectroscopies (UV-VUV emission and excitation, X-ray absorption near-edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS)). Special attention was paid on the effect of the R3+ co-dopants on the persistent luminescence properties of the materials. Theoretical calculations using the density functional theory (DFT) were carried out simultaneously with the experimental work. The experimental band gap energy (Eg) value of ca. 7.1 eV agreed very well with the DFT value of 6.7 eV. The variation of the Eg value was attempted to relate with the trap structure as well as with the different properties of the R3+ co-dopants. The trap level energy distribution depended strongly on the R3+ co-dopant except for the shallowest trap energy above the room temperature remaining practically the same, however. The different processes in the mechanism of persistent luminescence from Sr2MgSi2O7:Eu2+,R3+ were assembled and their contributions discussed.Tuomas Aitasalo Jukka Hassinen Jorma Hls Taneli Laamanen Mika Lastusaari Marja Malkamki Janne Niittykoski Pavel Novák 2009Journal of Rare Earths2009,27,4:5
2Bile 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 2020World Journal of Gastrointestinal Surgery2020,12,1:4
3Systematic 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 2018World Journal of Gastrointestinal Surgery2018,10,6:3

19Cost-effectiveness in Clostridium difficile treatment decision-making显示文摘AIM: To develop a framework for the clinical and health economic assessment for management of Clostridium difficile infection(CDI).METHODS: CDI has vast economic consequences emphasizing the need for innovative and cost effective solutions, which were aim of this study. A guidance model was developed for coverage decisions and guideline development in CDI. The model included pharmacotherapy with oral metronidazole or oral vancomycin, which is the mainstay for pharmacological treatment of CDI and is recommended by most treatment guidelines.RESULTS: A design for a patient-based cost-effectiveness model was developed, which can be used to estimate the cost-effectiveness of current and future treatment strategies in CDI. Patient-based outcomes were extrapolated to the population by including factors like, e.g., person-to-person transmission, isolation precautions and closing and cleaning wards of hospitals. CONCLUSION: The proposed framework for a population-based CDI model may be used for clinical and health economic assessments of CDI guidelines and coverage decisions for emerging treatments for CDI.Mark JC Nuijten Josbert J Keller Caroline E Visser Ken Redekop Eric Claassen Peter Speelman Marja H Pronk 2015World Journal of Clinical Cases2015,3,11:0
