1Factors affecting healing after arthroscopic rotator cuff repair显示文摘Rotator cuff repair has been shown to have good longterm results. Unfortunately, a significant proportion of repairs still fail to heal. Many factors, both patient and surgeon related, can influence healing after repair. Older age, larger tear size, worse muscle quality, greater muscle-tendon unit retraction, smoking, osteoporosis, diabetes and hypercholesterolemia have all shown to negatively influence tendon healing. Surgeon related factors that can influence healing include repair construct-single vs double row, rehabilitation, and biologics including platelet rich plasma and mesenchymalstem cells. Double-row repairs are biomechanically stronger and have better healing rates compared with single-row repairs although clinical outcomes are equivalent between both constructs. Slower, less aggressive rehabilitation programs have demonstrated improved healing with no negative effect on final range of motion and are therefore recommended after repair of most full thickness tears. Additionally no definitive evidence supports the use of platelet rich plasma or mesenchymal stem cells regarding improvement of healing rates and clinical outcomes. Further research is needed to identify effective biologically directed augmentations that will improve healing rates and clinical outcomes after rotator cuff repair.Amir M Abtahi Erin K Granger Robert Z Tashjian 2015World Journal of Orthopedics2015,6,2:16
2Systematic review and meta-analysis on the prophylactic role of non-steroidal anti-inflammatory drugs to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis显示文摘AIM: To critically appraise the published randomized, controlled trials on the prophylactic effectiveness of the non-steroidal anti-inflammatory drugs(NSAIDs), in reducing the risk of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis. METHODS: A systematic literature search(MEDLINE, Embase and the Cochrane Library, from inception of the databases until May 2015) was conducted to identify randomized, clinical trials investigating the role of NSAIDs in reducing the risk of post-ERCP pancreatitis. Random effects model of the meta-analysis was carried out, and results were presented as odds ratios(OR) with corresponding 95%CI.RESULTS: Thirteen randomized controlled trials on 3378 patients were included in the final meta-analysis. There were 1718 patients in the NSAIDs group and 1660 patients in non-NSAIDs group undergoing ERCP. The use of NSAIDs(through rectal route or intramuscular route) was associated with the reduced risk of post-ERCP pancreatitis [OR, 0.52(0.38-0.72), P = 0.0001]. The use of pre-procedure NSAIDs was effective in reducing approximately 48% incidence of post-ERCP pancreatitis, number needed to treat were 16 with absolute risk reduction of 0.05. But the risk of post-ERCP pancreattis was reduced by 55% if NSAIDs were administered after procedure. Similarly, diclofenac was more effective(55%) prophylactic agent compared to indomethacin(41%).CONCLUSION: NSAIDs seem to have clinically proven advantage of reducing the risk of post-ERCP pancreatitis.Muhammad S Sajid Amir H Khawaja Mazin Sayegh Krishna K Singh Zinu Philipose 2015World Journal of Gastrointestinal Endoscopy2015,7,19:14
3sTREM-1 is a specific biomarker of TREM-1 pathway activation显示文摘TREM-1(triggering receptor expressed on myeloid cells-1)is a transmembrane receptor expressed by innate immune cells,including endothelial cells and platelets.TREM-1 is a crucial mediator of septic shock that acts by synergizing with Toll-like receptors(TLRs)to amplify the inflammatory responses to pathogens,thus promoting sepsis-induced immune dysregulation and organ dysfunction[1,2,3].Lucie Jolly Kévin Carrasco Margarita Salcedo-Magguilli Jean-Jacques Garaud Simon Lambden Tom van der Poll Alexandre Mebazaa Pierre-François Laterre Sebastien Gibot Amir Boufenzer Marc Derive 2021Cellular & Molecular Immunology2021,18,8:8
4Automatic fuzzy-DBSCAN algorithm for morphological and overlapping datasets显示文摘Clustering is one of the unsupervised learning problems.It is a procedure which partitions data objects into groups.Many algorithms could not overcome the problems of morphology,overlapping and the large number of clusters at the same time.Many scientific communities have used the clustering algorithm from the perspective of density,which is one of the best methods in clustering.This study proposes a density-based spatial clustering of applications with noise(DBSCAN)algorithm based on the selected high-density areas by automatic fuzzy-DBSCAN(AFD)which works with the initialization of two parameters.AFD,by using fuzzy and DBSCAN features,is modeled by the selection of high-density areas and generates two parameters for merging and separating automatically.The two generated parameters provide a state of sub-cluster rules in the Cartesian coordinate system for the dataset.The model overcomes the problems of clustering such as morphology,overlapping,and the number of clusters in a dataset simultaneously.In the experiments,all algorithms are performed on eight data sets with 30 times of running.Three of them are related to overlapping real datasets and the rest are morphologic and synthetic datasets.It is demonstrated that the AFD algorithm outperforms other recently developed clustering algorithms.YELGHI Aref KÖSE Cemal YELGHI Asef SHAHKAR Amir 2020Journal of Systems Engineering and Electronics2020,31,6:5

7Semi-active fuzzy control of Lali Cable-Stayed Bridge using MR dampers under seismic excitation显示文摘Seismic control of cable-stayed bridges is of paramount importance due to their complex dynamic behavior,high flexibility,and low structural damping.In the present study,several semi-active Fuzzy Control Algorithms(FCAs)for vibration mitigation of Lali Cable-Stayed Bridge are devised.To demonstrate the efficiency of the algorithms,a comprehensive nonlinear 3-D model of the bridge is created using OpenSees.An efficient method for connecting MATLAB and OpenSees is devised for applying FCAs to the structural model of the bridge.Two innovative fuzzy rulebases are introduced.A total of six different fiuzzy rule-bases are utilized.The efficiency of the FCAs is evaluated in a comparative manner.The performance of fuzzy control systems is also compared with a sky-hook and a passive-on system.Moreover,the sensitivity of efficiency of control systems to the peak ground acceleration is evaluated qualitatively.In addition,the effect of time lag is also investigated.This study thoroughly examines the efficiency of the FCAs in different aspects.Therefore,the results can be regarded as a general guide to design semi-active fuzzy control systems for vibration mitigation of cable-stayed bridges.Sajad JAVADINASAB HORMOZABAD Amir K GHORBANI-TANHA 2020Frontiers of Structural and Civil Engineering2020,14,3:1
