Des lieux infinis pour rassembler
No full textInternational audienceLe catalogue d’exposition du Pavillon français de la dernière Biennale internationale d’Architecture de Venise interroge des Lieux infinis, présentés par les architectes et commissaires d’exposition Nicola Delon, Julien Choppin et Sébastien Eymard, membres du collectif Encore Heureux. À travers deux grands axes, Dire et Agir, ils rassemblent des personnalités issues de diverses disciplines : Alexa Brunet, photographe ; Luc Gwiazdzinski, géographe ; Pascal Nicolas-Le Strat, sociologue ; Raphaël Besson, expert en économie urbaine ; Fazette Bordage, créatrice de lieux ; Joëlle Zask, philosophe ; Patrick Perez, architecte anthropologue ; Jade Lindgaard, journaliste ; Patrick Viveret, philosophe ; Gilles Clément, paysagiste ; Patrick Bouchain, architecte ; Jochen Gerner, illustrateur
Nachweis pathogener Keime in Lebergewebe und Galle bei Patienten während Lebertransplantation
No full textInfektionen haben einen großen Einfluß auf Morbidität und Letalität nach Lebertransplantation. Dennoch gibt es kaum Daten zu der Prävalenz, dem mikrobiologischen Spektrum und den Antibiotikaresistenzen von Keimbesiedlung in Galle und Lebergewebe bei leberkranken Patienten zum Zeitpunkt ihrer Transplantation.
Ziel der vorliegenden Studie war es dies für ein Kollektiv von 52 Patienten des Uniklinikum Essens zu ermitteln.
Dabei kamen kulturelle und molekulargenetische Nachweismethoden zum Einsatz.
Es konnten bei 35 % aller Patientin in Lebergewebe und/oder Galle Bakterien und/oder Pilzen nachgewiesen werden.
Bei 4 Patienten konnten Koagulase-negative Staphylokokken nachgewiesen werden, gefolgt von Escherichia coli, Enterococcus faecium/faecalis und Klebsiella spp. bei jeweils 3 Patienten. Weitere Nachweise waren unter anderem Candida spp., Pseudomonas spp., Enterobacter cloacae, Hafnia alvei, Stenotrophomonas maltophilia, Lactobacillus gasseri, Aeromonas hydrophila.
Bei allen nachgewiesenen Bakterien und Pilzen handelte es sich um fakultativ pathogene Keime, die vor allem bei immunsupprimierten Patienten schwere Infektionen auslösen können
Frontiers in Neurology / Automatic vs. Manual Detection of High Frequency Oscillations in Intracranial Recordings From the Human Temporal Lobe
No full textBackground: High frequency oscillations (HFOs) have attracted great interest among neuroscientists and epileptologists in recent years. Not only has their occurrence been linked to epileptogenesis, but also to physiologic processes, such as memory consolidation. There are at least two big challenges for HFO research. First, detection, when performed manually, is time consuming and prone to rater biases, but when performed automatically, it is biased by artifacts mimicking HFOs. Second, distinguishing physiologic from pathologic HFOs in patients with epilepsy is problematic. Here we automatically and manually detected HFOs in intracranial EEGs (iEEG) of patients with epilepsy, recorded during a visual memory task in order to assess the feasibility of the different detection approaches to identify task-related ripples, supporting the physiologic nature of HFOs in the temporal lobe.
Methods: Ten patients with unclear seizure origin and bilaterally implanted macroelectrodes took part in a visual memory consolidation task. In addition to iEEG, scalp EEG, electrooculography (EOG), and facial electromyography (EMG) were recorded. iEEG channels contralateral to the suspected epileptogenic zone were inspected visually for HFOs. Furthermore, HFOs were marked automatically using an RMS detector and a Stockwell classifier. We compared the two detection approaches and assessed a possible link between task performance and HFO occurrence during encoding and retrieval trials.
Results: HFO occurrence rates were significantly lower when events were marked manually. The automatic detection algorithm was greatly biased by filter-artifacts. Surprisingly, EOG artifacts as seen on scalp electrodes appeared to be linked to many HFOs in the iEEG. Occurrence rates could not be associated to memory performance, and we were not able to detect strictly defined “clear” ripples.
Conclusion: Filtered graphoelements in the EEG are known to mimic HFOs and thus constitute a problem. So far, in invasive EEG recordings mostly technical artifacts and filtered epileptiform discharges have been considered as sources for these “false” HFOs. The data at hand suggests that even ocular artifacts might bias automatic detection in invasive recordings. Strict guidelines and standards for HFO detection are necessary in order to identify artifact-derived HFOs, especially in conditions when cognitive tasks might produce a high amount of artifacts.Aljoscha Thomschewski, Nathalie Gerner, Patrick B.
