Abstract

In partnership with the Memorial University of Newfoundland, the Vista School District, 1 of 10 districts in Newfoundland, Canada, established the Vista School District Digital Intranet (VSDDI) to deliver Web-based advanced placement courses to rural students. Advanced placement mathematics, physics, biology, and chemistry courses are delivered via a district digital intranet that connects all district senior high schools and the Memorial University of Newfoundland. Each participating school has a school intranet linked to a satellite dish that provides access to the VSDDI intranet and the Internet. Instruction includes both synchronous and asynchronous components. Synchronous instruction allows students in multiple, rural schools to communicate in real time with each other and with their instructor, using whiteboards, chat, video, and voice communication. The asynchronous component provides student access to lessons, a bulletin board, private email, a calendar, tests, presentations, individual evaluation records, and a software package that allows students and instructors in separate schools and different times to take part in a virtual classroom discussion. As of September 1999, the program has been expanded to 5 of the 10 school districts in Newfoundland. The URL is included. (TD)

Abstract

Background/objective: Prostar XL (PS) and ProGlide (PG) are common vascular closure devices (VCD) used in TAVR via transfemoral vascular approach. The impact of these VCD on vascular and bleeding complications remains unclear., Methods: The BRAVO-3 trial randomized 802 patients undergoing transfemoral TAVR. We stratified patients according to type of VCD used and examined the 30-day incidence of major or minor vascular complications, major bleeding (BARC ≥3b), AKI and major adverse cardiac and cerebrovascular events (MACCE; death, myocardial infarction or stroke)., Results: A total of 746 (93%) patients were treated with either PS (n = 352, 47%) or PG (n = 394, 53%) VCD, without significant differences in successful deployment rate (PS 322 [91.2%] vs. PG 373 [94.2%] respectively, p = .20). PG was associated with a significantly lower incidence of major or minor vascular complications, compared to PS (adjusted OR: 0.54; 95% CI: 0.37-0.80; p < .01). Rates of acute kidney injury were also lower with the PG device. There was no significant difference between bleeding, MACCE, and death., Conclusions: Compared to PS, the PG VCD was associated with a lower rate of major or minor vascular complications and lower rates of AKI after transfemoral TAVR., (© 2019 Wiley Periodicals, Inc.)
