Social security, care and the "withdrawing state" in rural Russia
No full textThis chapter presents the development of a research project, exploring the ways in which social security is produced and experienced in rural Russia. Based on a case study of Burla village, the project investigates the ways in which caring practices and material support are provided by and exchanged within a range of formal and informal, state and non-state, community and kinship structures
This chapter begins by exploring the theoretical and contextual frameworks for the study through a discussion of theoretical approaches to understanding “social security”, “care” and “the state”, followed by a review of existing literature on welfare, social security and rural life in contemporary Russia. It then goes on to present and discuss early findings from fieldwork conducted in March 2008 and April 2009

No full textNeo Left Main Channel Creation Using Double Stenting Alongside a Sapien 3 Aortic Valve Bioprosthesis for Left Main Coronary Obstruction Following Valve-in-Valve Transcatheter Aortic Valve Replacement: A Case Report With Review of Literature
No full textTranscatheter aortic valve replacement in the setting of failed surgical bioprosthesis (valve-in-valve) is a valuable option for patients with bioprosthetic aortic stenosis or regurgitation who are deemed high risk for repeat open heart surgery. Although the procedure is successful with proper preprocedural assessment, instances of left main (LM) coronary artery ostium obstruction have been documented. We present a case of LM coronary obstruction in the immediate postoperative period following implantation of a 20-mm Edwards Sapien 3 valve inside the degenerated 21-mm Mitroflow bioprosthesis stenosis, which was treated with double stenting alongside the Edwards Sapien 3 valve creating a channel (“neo left main”) that extended from mid-LM to the upper margin of the Edwards Sapien 3 valve. Although valve-in-valve in a Mitroflow degenerated bioprosthesis is a relatively safe procedure, 2 or more stents may be necessary to scaffold a channel to the coronary arteries between Edwards Sapien 3 prosthesis and aorta in the event of a coronary obstruction
The development or worsening of hypertension after transcatheter aortic valve replacement (TAVR) improves short-term and long-term patient outcomes
No full textNovel solution for luminal access loss into the double-layered LVIS Blue™ construct
No full text We described a novel solution for a challenging case of double-layered LVIS Blue™ (LB) stent construct retraction into a large cavernous aneurysm. The double-layered LB stent construct was used as a flow diverter for treatment of a large cavernous aneurysm. Our solution comprised a balloon angioplasty and placement of balloon-mounted cardiac-stent construct through the side wall of the LB construct, with eventual placement of a Pipeline Flex inside of the final conduit. </jats:p
THE EFFECT OF WARFARIN ON PROSTHETIC VALVE FUNCTION AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT
No full textThe angiographic step-up and step-down: a surrogate for optimal stent expansion by intravascular ultrasound.
No full textBACKGROUND: Standard high-pressure stent implantation frequently results in suboptimal stent expansion by intravascular ultrasound (IVUS) criteria. We aim to show that routine expansion of the stent to a diameter greater than the reference segment, leading to an angiographic step-up at the proximal stent edge and step-down at the distal stent edge, results in improved stent expansion.
METHODS: We studied 25 patients undergoing coronary stent implantation. Twelve patients were randomized to standard sizing and 13 patients to step-up and step-down sizing as the angiographic goal. IVUS was then performed on all patients to detect incomplete stent strut apposition, dissection within the stent or a suboptimal stent expansion index (SEI). SEI was defined as the minimum stent area (MSA)/average reference lumen area x 100. Optimal SEI was defined as greater than or equal to 90% for a MSA less than or equal to 9.0 mm2 and greater than or equal to 80% for a MSA \u3e9.0 mm2.
RESULTS: Four patients (33%) treated with standard stent implantation and 12 patients (92%) treated with the step-up and step-down approach (p = 0.004) achieved optimal stent expansion. No patients in either group had unapposed stent struts or instent dissection on IVUS. There were no major adverse cardiac events on 6-month follow up.
CONCLUSIONS: Stent deployment with an angiographic step-up and step-down approach improves the likelihood of optimal stent deployment by IVUS criteria as compared to the standard angiographic endpoint. This stenting technique is a simple and frugal alternative to IVUS-guided percutaneous coronary intervention, achieving very high rates of adequate stent apposition and expansion
Congratulations! Frank Low Research Day award winners named
No full textWe want to thank all of you who participated in making the 37th Annual Frank N. Low Research Day a success. We appreciate the high level of participation by students, faculty, and staff at the School of Medicine and Health Sciences. Special thanks to UND Vice President for Health Affairs and Dean of the School of Medicine and Health Sciences Joshua Wynne, MD, MBA, MPH, for ongoing support of this important annual event and for providing welcoming remarks for the keynote speaker.
We were pleased to have keynote speaker T. Colin Campbell, PhD, Jacob Gould Schurman Professor Emeritus of Nutritional Biochemistry at Cornell University, present his address, “Nutrition should be a medical specialty.” He serves on the board of the Ithaca, New York, based T. Colin Campbell Center for Nutrition Studies.
Participants presented 109 posters. Invited talks were given by Travis Alvine, SMHS Department of Biomedical Sciences, (mentor: David Bradley), Peter Knopick, Department of Biomedical Sciences, (mentor: David Bradley), Timothy Casselli, postdoctoral, (mentor: John Watt), Brandon Fisher, medical student, (mentor: Dinesh Bande and Tze Lo), Samantha Guenther, Department of Occupational Therapy, (mentor: Janet Jedlicka), Brent Klinkhammer, resident, (mentor: Thomas Haldis), Waqas Kayani, resident, (mentor: Dr. Khan), and Alexander Fife, medical student, (mentor: Suba Nookala).
Among the poster judges was special guest Professor Kurt H. Albertine, PhD, University of Utah School of Medicine in Salt Lake City, whose research focuses on acute and chronic lung disease, with an emphasis on neonatal chronic lung disease. He is the editor of the Anatomical Record, a journal of the American Association of Anatomists. He was visiting the School to honor Edward Carlson, PhD, Chester Fritz Distinguished Professor Emeritus and Karl and Carolyn Kaess Professor of Anatomy and Cell Biology. Albertine volunteered to be a judge when he heard that his visit coincided with Frank N. Low Research Day.
Special thanks go to Assistant Professor Xuesong Chen, PhD, Department of Biomedical Sciences, and Frank N. Low Research Day Coordinator Joann Johnson, whose efforts ensured the success of the event.
