The Society for Vascular Surgery: As I remember – An interview with Dr. Michael E. DeBakey

AbstractAs part of the activities to celebrate the first fifty years of the Society, the Celebration Committee decided to conduct a videotape interview of the two surviving founding members: Drs. Michael E. DeBakey and Harris B. Shumacker, Jr. Part of these two interviews will be shown at the 50th Annual Meeting in Chicago. The following transcript is from the interview with Dr. DeBakey conducted by Dr. F. William Blaisdell, Calvin B. Ernst, and James S. T. Yao

The Role of Organizational Culture on a Subculture of Feedback

Hysong: The Role Of Organizational Culture On A Subculture Of Feedback [http://nbn-resolving.de/urn:nbn:de:kobv:83-opus4-54163]Organizational culture has long been studied in relationship to organizational performance, though this relationship has not been established consistently. Martin (2002) suggested the simultaneous existence of a general culture, and multiple, context-specific subcultures in an organization. Are subcultures simply context-specific reflections of the larger organizational culture? Or do they serve as potential moderators of the relationship between the larger organizational culture and organizational performance? To explore this question, we employed ATLAS.ti 6.2 to conduct a content analysis of organizational culture at four United States Department of Veterans Affairs Medical Centers (VAMCs). Sites were selected purposely based on their performance on 15 clinical measures. At each facility we conducted one-hour telephone interviews of the facility director, the director of primary care, and one full-time primary care physician and nurse. Participants answered questions about the types of clinical performance information they receive, and seek out, the utility of such data, and how they use said information. Each site’s culture was highly distinct. However, despite these differences across sites, the mirror relationship between organizational culture and feedback subculture was present in all four sites, suggesting the subculture is a reflection of the parent culture

Rotary blood pump

A blood pump that comprises a pump housing having a blood flow path therethrough, a blood inlet, and a blood outlet; a stator mounted to the pump housing, the stator having a stator field winding for producing a stator magnetic field; a flow straightener located within the pump housing, and comprising a flow straightener hub and at least one flow straightener blade attached to the flow straightener hub; a rotor mounted within the pump housing for rotation in response to the stator magnetic field, the rotor comprising an inducer and an impeller; the inducer being located downstream of the flow straightener, and comprising an inducer hub and at least one inducer blade attached to the inducer hub; the impeller being located downstream of the inducer, and comprising an impeller hub and at least one impeller blade attached to the impeller hub; and preferably also comprising a diffuser downstream of the impeller, the diffuser comprising a diffuser hub and at least one diffuser blade. Blood flow stagnation and clot formation within the pump are minimized by, among other things, providing the inducer hub with a diameter greater than the diameter of the flow straightener hub; by optimizing the axial spacing between the flow straightener hub and the inducer hub, and between the impeller hub and the diffuser hub; by optimizing the inlet angle of the diffuser blades; and by providing fillets or curved transitions between the upstream end of the inducer hub and the shaft mounted therein, and between the impeller hub and the shaft mounted therein
