    International audienceHave you ever dreamed of having eyes in the back of your head? In this paper we present a novel display device called FlyVIZ which enables humans to experience a real-time 360° vision of their surroundings for the first time. To do so, we combine a panoramic image acquisition system (positioned on top of the user's head) with a Head-Mounted Display (HMD). The omnidirectional images are transformed to fit the characteristics of HMD screens. As a result, the user can see his/her surroundings, in real-time, with 360° images mapped into the HMD field-of- view. We foresee potential applications in different fields where augmented human capacity (an extended field-of-view) could benefit, such as surveillance, security, or entertainment. FlyVIZ could also be used in novel perception and neuroscience studies

    International audienceBACKGROUND: Cardiogenic shock (CS) complicating acute myocardial infarction (AMI) remains a major concern. Failure of the left ventricular (LV) pump is the primary insult in most forms of CS, but other parts of the circulatory system and diastolic function contribute to shock. However, little is known of the clinical presentation, management and outcomes according to LV function in these patients.OBJECTIVES: To assess the presentation, management and clinical outcomes in patients admitted for AMI with CS according to early LV ejection fraction (LVEF), using long-term data from the French registry of Acute ST-elevation or non-ST-elevation Myocardial Infarction (FAST-MI) 2010.METHODS: We analysed baseline characteristics, management and 3-year mortality in patients with CS, according to LVEF (≀40% vs>40%). The analyses were replicated in the FAST-MI 2005 cohort.RESULTS: Among 4169 patients with AMI included in the survey, the incidence of CS was 3.3%. LVEF was>40% in 43%. Early PCI (≀24hours) was used more often in patients with LV dysfunction (61% vs 42%), as was the use of optimal medical therapy at discharge (66% vs 40%). CS remained associated with a major increase in 3-year mortality, both in patients with LVEF ≀40% (55%) and in those with LVEF>40% (44%). Using Cox multivariable analysis, LVEF ≀40% was associated with higher 3-year mortality (hazard ratio 2.08, 95% confidence interval 1.15-3.78) in patients with AMI with CS. Consistent results were found in the replication cohort.CONCLUSIONS: Despite the many circulatory system contributors to the physiopathology of CS in patients with AMI, the occurrence of early LV systolic dysfunction is associated with higher long-term mortality.Contexte: Le choc cardiogĂ©nique (CC) reste une complication redoutable de l’infarctus du myocarde (IDM). Il rĂ©sulte le plus souvent d’une dysfonction systolique sĂ©vĂšre mais la dysfonction diastolique ainsi que la vasodilatation pĂ©riphĂ©rique consĂ©quence du syndrome de rĂ©ponse inflammatoire systĂ©mique peuvent contribuer aux mĂ©canismes du choc. Pourtant peu de donnĂ©es sont disponibles sur l’épidĂ©miologie des patients prĂ©sentant un IDM compliquĂ© de CC en fonction de la fonction ventriculaire gauche (VG).Objectifs: Évaluer la prĂ©sentation clinique, la prise en charge et la mortalitĂ© Ă  trois ans des patients avec CC Ă  la phase aiguĂ« d’un IDM en fonction de la prĂ©sence ou non d’une dysfonction VG (DVG) Ă  partir des donnĂ©es de FAST-MI2010.MĂ©thodes: Les patients avec DVG (fraction d’éjection VG [FEVG] ≀ 40 %) Ă©taient comparĂ©s aux patients sans DVG. Les analyses Ă©taient rĂ©pliquĂ©es dans la cohorte FAST-MI 2005.RĂ©sultats: Parmi les 4169 patients ayant prĂ©sentĂ© un IDM, 3,3 % des patients ont prĂ©sentĂ© un CC dont 43 % avec FEVG > 40 %. L’angioplastie percutanĂ©e prĂ©coce (≀ 24 heures) Ă©tait utilisĂ©e plus souvent chez les patients avec DVG (61 % vs 42 %). Le CC restait associĂ© Ă  une mortalitĂ© Ă©levĂ©e Ă  trois ans dans les deux groupes ; 55 % chez le groupe FEVG ≀ 40 % et 44 % dans le groupe FEVG > 40 %. En analyse multivariĂ©e, la DVG < 40 % Ă©tait associĂ©e Ă  une surmortalitĂ© Ă  trois ans (HR 2,08, IC95 % 1,15–3,78) chez les patients en CC. L’analyse dans la cohorte 2005 retrouvait des rĂ©sultats similaires.Conclusions: MalgrĂ© une physiopathologie complexe du CC compliquant l’IDM, la DVG ≀ 40 % reste associĂ© Ă  une mortalitĂ© Ă©levĂ©e Ă  trois ans
