Core set of unfavorable events of shoulder arthroplasty: an international Delphi consensus process

BackgroundShoulder arthroplasty (SA) complications require standardization of definitions and are not limited to events leading to revision operations. We aimed to define an international consensus core set of clinically relevant unfavorable events of SA to be documented in clinical routine practice and studies.MethodsA Delphi exercise was implemented with an international panel of experienced shoulder surgeons selected by nomination through professional societies. On the basis of a systematic review of terms and definitions and previous experience in establishing an arthroscopic rotator cuff repair core set, an organized list of SA events was developed and reviewed by panel members. After each survey, all comments and suggestions were considered to revise the proposed core set including local event groups, along with definitions, specifications, and timing of occurrence. Consensus was reached with at least two-thirds agreement.ResultsTwo online surveys were required to reach consensus within a panel involving 96 surgeons. Between 88% and 100% agreement was achieved separately for local event groups including 3 intraoperative (device, osteochondral, and soft tissue) and 9 postoperative event groups. Experts agreed on a documentation period that ranged from 3 to 24 months after SA for 4 event groups (peripheral neurologic, vascular, surgical-site infection, and superficial soft tissue) and that was lifelong until implant revision for other groups (device, osteochondral, shoulder instability, pain, late hematogenous infection, and deep soft tissue).ConclusionA structured core set of local unfavorable events of SA was developed by international consensus to support the standardization of SA safety reporting. Clinical application and scientific evaluation are needed.</div

Petri nets as Executable Specifications of High-Level Timed Parallel Systems

International audienceWe propose to use high-level Petri nets for the semantics of high-level parallel systems. This model is known to be useful for the of verification and we show that it is also executable in a parallel way. Executing a Petri net is easy in general but more complicated in a timed context, which makes necessary to synchronise the internal time of the Petri net with the real time of its environment. Another problem is to relate the execution of a Petri net, which has its own semantics, to that of its environment; i.e., to properly handle input/output. This paper presents a parallel algorithm to execute Petri nets with time enforcing the even progression of the internal time with respect to the real time and allowing the exchange of information with the environment. We define a class of Petri nets suitable for a parallel execution machine which preserves the step sequence semantics of the nets and ensures time consistent executions while taking into account the solicitation of its environment. The question of the efficient verification of such nets has been addressed in a separate paper, the present one is focused on the practical aspects involved in the execution of so modelled systems

Sportmarken – Von traditionellen Ansätzen der Markenführung hin zum vernetzten Branding

Traditionelle Ansätze der Markenführung reichen aufgrund der zunehmenden Komplexität und Dynamik im Sportmanagement für eine erfolgreiche Markenführung nicht mehr aus. Sie folgen der Logik der Sportgüter, die sich zunehmend als eine Logik des Misslingens herausstellt. Das Vernetzte Branding folgt der Logik der Wert-Kokreation, die eine Logik des Gelingens darstellt. Das Vernetzte Branding besteht aus zwei Teilprozessen, die iterativ zur Anwendung kommen, dem Aufbau der Markenidentität und der Kokreation der Markenbedeutung. Insbesondere die Kokreation der Markenbedeutung stellt besondere Herausforderungen an den modernen Sportmanager, weil neben den fachlichen Kompetenzen auch überdurchschnittliche Fähigkeiten zum Lernen, zur Kommunikation und zum Ausgleich divergierender Interessen erforderlich sind. Vernetztes Branding ist ein Rezept für erfolgreiche Sportmarken
