OMEGA ICT project: Towards convergent gigabit home networks

Gigabit home networks represent a key technology to make the Future Internet success a reality. The OMEGA European project [1] aims to define and demonstrate such networks. Consumers will require networks to be simple to install, without the need of any new wire. To achieve this, gigabit radio links and wireless optics communications will provide wireless connectivity within the home and its surroundings. Power-line communications potentially combined with robust RF will provides a home backbone ???without new wires.??? To make this network ubiquitous, seamless and robust a technology- independent MAC layer will ensure its global control and provide connectivities to any number of devices the user wishes to connect to it in any room in a house or a flat. In order to make this vision come true, substantial progress is required in the fields of optical-wireless and RF physical layers, in protocol design, and in systems architectures

Prognostic performance of early absence of pupillary light reaction after recovery of out of hospital cardiac arrest

International audienceLoss of pupillary light reactivity (PLR) three days after a cardiorespiratory arrest is a prognostic factor. Its predictive value upon hospital admission remains unclear. Our objective was to determine the prognostic value of the absence of PLR upon hospital admission in patients with out-of-hospital cardiac arrest.We prospectively included all out-of-hospital cardiac arrests occurring between July 2011 and July 2017 treated by a mobile medical team (MMT) based on data from a French cardiac arrest registry database. PLR was evaluated upon hospital admission and the outcome on day 30. The prognosis was classified as good for Cerebral Performance Category (CPC) 1 or 2, and poor for CPC 3-5 or in case of death.Data from 10151 patients was analysed. The sensitivity and specificity of the absence of PLR for a poor outcome were 72.2% (71.2-73.2) and 68.8% (66.7-70.1), respectively. We identified several variables modifying the sensitivity values and the false positive fraction of a factor, ranging from 0.49 (0.35-0.69) for the Glasgow Coma Scale to 2.17 (1.09-2.48) for pupillary asymmetry. Among those living with CPC 1 or 2 on day 30 (n = 1990; 19.6%), 621 (31.2% (29.2-33.3)) had no PLR upon hospital admission. In the multivariate analysis, loss of PLR was associated with a poor outcome (OR = 3.1 (2.7-3.5)).Loss of pupillary light reactivity upon hospital admission is predictive of a poor outcome after out-of-hospital cardiac arrest. However, it does not have sufficient accuracy to determine prognosis and decision making
