Triage Considerations for Patients Referred for Structural Heart Disease Intervention During the Coronavirus Disease 2019 (COVID-19) Pandemic: An ACC /SCAI Consensus Statement
The COVID-19 pandemic has strained health care resources around the world causing many institutions to curtail or stop elective procedures. This has resulted in the inability to care for patients valvular and structural heart disease (SHD) in a timely fashion potentially placing these patients at increased risk for adverse cardiovascular complications including congestive heart failure and death. The effective triage of these patients has become challenging in the current environment as clinicians have had to weigh the risk of bringing susceptible patients into the hospital environment during the COVID-19 pandemic versus the risk of delaying a needed procedure. In this document, we suggest guidelines as to how to triage patients in need of SHD interventions and provide a framework of how to decide when it may be appropriate to proceed with intervention despite the ongoing pandemic. In particular, we address the triage of patients in need of trans-catheter aortic valve replacement and percutaneous mitral valve repair. We also address procedural issues and considerations for the function of structural heart disease teams during the COVID-19 pandemic
Triage Considerations for Patients Referred for Structural Heart Disease Intervention During the COVID-19 Pandemic: An ACC/SCAI Position Statement
The coronavirus disease-2019 (COVID-19) pandemic has strained health care resources around the world, causing many institutions to curtail or stop elective procedures. This has resulted in an inability to care for patients with valvular and structural heart disease in a timely fashion, potentially placing these patients at increased risk for adverse cardiovascular complications, including CHF and death. The effective triage of these patients has become challenging in the current environment as clinicians have had to weigh the risk of bringing susceptible patients into the hospital environment during the COVID-19 pandemic against the risk of delaying a needed procedure. In this document, the authors suggest guidelines for how to triage patients in need of structural heart disease interventions and provide a framework for how to decide when it may be appropriate to proceed with intervention despite the ongoing pandemic. In particular, the authors address the triage of patients in need of transcatheter aortic valve replacement and percutaneous mitral valve repair.

Students and academics working in partnership to embed cultural competence as a graduate quality
Since 2014, the University of Sydney has been experimenting with a new initiative motivated by the research on “students as partners”. In 2014, six students were selected as Ambassadors of the Sydney Teaching Colloquium (STC)-the University’s annual learning and teaching conference-as undergraduate researchers. In that year, the focus was on assessment standards
Returning to Text: Affect, meaning making and literacies
Existing work on literacy and affect has posed important questions for how we think about meanings and how
and where they get made. The authors contribute to such work by focusing on the relation between text and
affect. This is a topic that has received insufficient attention in recent work but is of pressing concern for
education as text interweaves in new ways with human activity, through social media, surveillance capitalism,
and artificial intelligence—ways that can be unpredictable and poorly understood. Adopting a sociomaterial
sensibility that foregrounds the relations between bodies (people and things), the authors provide conceptual
tools for considering how texts affect and are affected by the heterogeneous entanglements from which they
emerge. In situating their argument, the authors outline influential readings of Spinoza’s theories of affect,
explore how these have been mobilized in literacy research, and identify how text has been accommodated
within such research. Using texts from a political episode in the United Kingdom, the authors explore the idea of
social-material-textual affects to articulate relationships among humans, nonhumans, meaning making, and
literacies. The authors conclude by identifying four ways in which text participates in what happens, raising
questions about how different materializations of text (or indeed “not text”) are significant to the diversifying
communicative practices that inflect social, cultural, economic, and political life
Modeling and Simulation Study of an Industrial Radial Moving Bed Reactor for Propane Dehydrogenation Process
An accurate model is required to optimize the propane dehydrogenation reaction carried out in the radial moving bed reactors (RMBR). The present study modeled the RMBR using a plug flow reactor model incorporated with kinetic models expressed in simple power-law model. Catalyst activity and coke formation were also considered. The model was solved numerically by discretizing the RMBR in axial and radial directions. The optimized kinetic parameters were then used to predict the trends of propane conversion, temperature, catalyst activity and coke content in the RMBR along axial and radial directions. It was found that the predicted activation energies of the propane dehydrogenation, propane cracking and ethylene hydrogenation were in reasonable agreement with the experimental values reported in the literature. The model developed has accurately predicted the reaction temperature profile, conversion profile and catalyst coke content. The deviations of these simulated results from the plant data were less than 5%
