Para uma tanatologia dos estádios Olímpicos

The sociology of sport has over a 30-year history of developing a deeper understanding of urban life by conceptualizing the ways in which sport, both as a dominant cultural form, and as the infrastructure that houses it, is connected to the construct of community and identity.  Olympic stadiums, for example, are projected as symbols of global urban status, focal points for local collective identity, and as verification of urban regeneration success –that is, in a sense, as the concrete embodiment of the Olympic Dream.              So what happens when an Olympic stadium is abandoned or destroyed?  What happens when an Olympic stadium dies?  The purpose of this essay is to provoke thought about the role and meaning of Olympic stadium death. We draw upon media studies, gerontological, and thanatological literature to explore how former Olympic stadiums are presented in global media reports.  Situated in the notion that cultural objects have a biography of a life span much as individuals do (Kopytoff, 1986), we ultimately call for a thanatology of sports stadiums

Intra-operative Doppler Flow Measurement do not Predict ‘At-risk’ Status of Infrainguinal Bypass Grafts

Aims: Patients undergoing infrainguinal arterial reconstruction using vein conduits, frequently undergo intra-operative Doppler flow measurements to determine technical adequacy. The aim of this study was to determine the proportion of vein grafts with normal intra-operative haemodynamic parameters that were subsequently discovered to be ‘at risk’ on postoperative duplex surveillance scanning. Methods: We prospectively collected data on 82, primary infrainguinal vein bypass grafts. Post papaverine graft flow and peripheral resistance were measured using the Scimed Opdopw intra-operative Doppler machine. All grafts were determined to be technically adequate on the basis of measured peripheral resistance units (mPRU) being %1. At 1 week, a postoperative duplex surveillance scan was performed. At risk status was determined and compared to the intra-operative Doppler flow measurement. Statistical analysis was performed using the Mann–Whitney U-test. Results: The post-operative duplex scan demonstrated that 53 (65%) of the 82 vein bypass grafts were diagnosed as being ‘not at risk’; and 29 (35%) were regarded as at risk. When the groups were compared, there was no significant difference in intra-operative haemodynamic parameters between those not at risk and those at risk (PZ0.19, Mann–Whitney U-test). The 1 month primary patency rate was 79% with a secondary patency rate of 100%. Conclusion: Despite normal intra-operative Doppler flow measurements, 35% of vein grafts were regarded as being at risk at the 1 week post-operative duplex surveillance scan. No single value may be universally applicable for identifying at risk grafts intraoperatively. Indeed, graft failure appears to be a multifactorial process
