1Emergency department procedural sedation for primary electrical cardioversion — a comparison with procedural sedations for other reasons显示文摘BACKGROUND: Atrial fibrillation(AF) is the most common arrhythmia treated in the emergency department(ED), with primary electrical cardioversion(PEC) the preferred method of rhythm control. Anecdotally, patients undergoing ED procedural sedation(EDPS) for PEC differ from those requiring EDPS for other procedures: they are at higher risk of adverse events, and require fewer drugs and lower doses. We attempt to verify this using an EDPS registry at a Canadian, tertiary care teaching hospital.METHODS: This is a retrospective review of patients that underwent EDPS for the period of June 2006 to September 2014. We compared demographics, medication use and intra-procedural adverse events between those receiving EDPS for PEC for AF compared to that for other indications. We report the asssociation between AEs and predictors using logistic regression.RESULTS: A total of 4 867 patients were included, 714 for PEC for AF and 4 153 for other indications. PEC patients were more likely male(58.5% vs. 47.1%), older(59.5 years vs. 48.1 years), and less likely to be ASA I(46.6% vs. 69.0%). PEC patients received smaller doses of propofol and less likely to receive adjuvant analgesic therapy(11.5% vs. 78.2%). PEC patients were more likely to experience hypotension(27.6% vs. 16.5%) but respiratory AEs(apnea, hypoxia and airway intervention) were not different.CONCLUSION: EDPS for PEC differs from that conducted for other purposes: patients tend to be less healthy, receive smaller doses of medication and more likely to suffer hypotension without an increase in respiratory AEs. These factors should be considered when performing EDPS.Michael Butler Patrick Froese Peter Zed George Kovacs Robert Mac Kinley Kirk Magee Mary-Lynn Watson Samuel G.Campbell 2017World Journal of Emergency Medicine2017,8,3:6
2Endothelial progenitor cells:Exploring the pleiotropic effects of statins显示文摘Statins have become a cornerstone of risk modification for ischaemic heart disease patients. A number of studies have shown that they are effective and safe. However studies have observed an early benefit in terms of a reduction in recurrent infarct and or death after a myocardial infarction,prior to any significant change in lipid profile. Therefore,pleiotropic mechanisms,other than lowering lipid profile alone,must account for this effect. One such proposed pleiotropic mechanism is the ability of statins to augment both number and function of endothelial progenitor cells. The ability to augment repair and maintenance of a functioning endothelium may have profound beneficial effect on vascular repair and potentially a positive impact on clinical outcomes in patients with cardiovascular disease. The following literature review will discuss issues surrounding endothelial progenitor cell(EPC) identification,role in vascular repair,factors affecting EPC numbers,the role of statins in current medical practice and their effects on EPC number.Kully Sandhu Mamas Mamas Robert Butler 2017World Journal of Cardiology2017,9,1:5

4Mechanical behavior predictions of additively manufactured microstructures using functional Gaussian process surrogates显示文摘Relational linkages connecting process,structure,and properties are some of the most sought after goals in additive manufacturing(AM).This is desired especially because the microstructural grain morphologies of AM components can be vastly different than their conventionally manufactured counterparts.Furthermore,data collection at the microscale is costly.Consequently,this work describes and demonstrates a methodology to link microstructure morphology to mechanical properties using functional Gaussian process surrogate models in a directed graphical network capable of achieving near real-time property predictions with single digit error magnitudes when predicting full stress–strain histories of a given microstructure.This methodology is presented and demonstrated using computationally generated microstructures and results from crystal plasticity simulations on those microstructures.The surrogate model uses grain-level microstructural descriptors rather than whole microstructure descriptors so that properties of new,arbitrary microstructures can be predicted.The developed network has the potential to scale to predict mechanical properties of grain structures that would be infeasible to simulate using finite element methods.Robert Saunders Celia Butler John Michopoulos Dimitris Lagoudas Alaa Elwany Amit Bagchi 2021npj Computational Materials2021,,1:3
