Background - We determined the predictive power of semi-automated blood-brain barrier assessment and other variables collected during neurocritical care for the outcome of ‘epilepsy or late death’ following aneurysmal subarachnoid haemorrhage. - Methods - This is a secondary analysis of the prospective, non-interventional, prognostic DISCHARGE-1-cohort from six university hospitals in Germany. All patients who underwent at least one contrast-enhanced MRI during neurocritical care were included. Initial clinical scores and Modified Rankin Scale at day 14 were available. Subdural electrocorticography was scored for seizures and spreading depolarisations. Two MRIs, one post-aneurysm occlusion and another post-neuromonitoring, were semi-automatically segmented into cerebrospinal fluid spaces, normal brain tissue, and abnormal brain tissue. Normal and abnormal tissue were further classified into tissue with “intact” or “dysfunctional” blood-brain barrier. Epilepsy and late death were determined at a median of 3.7 years. - Findings - Abnormal, barrier-dysfunctional tissue as a percentage of intracranial volume on post-monitoring MRI was the only independent predictor of early death within three weeks among 130 patients. In the 121 early survivors, this variable was also the only independent predictor of ‘epilepsy or late death’. This result, obtained by a combination of imputation and the leaving-one-out method, was confirmed in two sensitivity analyses within smaller populations and with fewer missing values. - Interpretation - The study substantiates previous experimental evidence that blood-brain barrier dysfunction plays a key role in epileptogenesis after brain injuries. Contrast-enhanced MRI, a minimally invasive technique, highlighted abnormal, barrier-dysfunctional tissue as a stand-alone independent predictor, underscoring its potential as a ‘precision medicine’ tool in early diagnosis and intervention. - Funding - JPD and AF report a grant from the Era-Net Neuron EBio2 with funds from BMBF 01EW2004 and CIHR Award No. NDD 168164.

The cooperative maneuver coordination allows for automated and connected vehicles to execute cooperative driving maneuvers, in order to increase the traffic safety and efficiency on the roads. The development of the associated cooperative driving functions requires a comprehensive testing, due to a large number of aspects needed to be considered. This dissertation introduces a novel methodology for the verification and validation of the cooperative driving functions with an intelligent co-simulation framework, including the approaches considering the preparation of scenarios through machine learning, the coupled simulation of vehicle and traffic, as well as the application of relevant traffic quality metrics. Eventually, a simulation-based Remote-Adaptable Prototype-in-the-Loop method is presented in the context of mixed reality, offering a solution for a fast and effort-efficient testing of the cooperative driving functions.
Die kooperative Manöverkoordinierung ermöglicht es den automatisierten und vernetzten Fahrzeugen kooperative Fahrmanöver auszuführen, um die Verkehrssicherheit und -effizienz auf den Straßen zu erhöhen. Die Entwicklung von dazugehörigen kooperativen Fahrfunktionen bedarf eines umfassenden Testens aufgrund einer großen Anzahl zu berücksichtigender Aspekte. Diese Dissertation schlägt eine neuartige Methodik zur Verifizierung und Validierung von kooperativen Fahrfunktionen durch ein Intelligent Co-Simulation Framework vor, inklusive der Ansätze hinsichtlich der Vorbereitung von Szenarien durch maschinelles Lernen, der gekoppelten Simulation von Fahrzeug und Verkehr sowie der Anwendung von relevanten Metriken der Verkehrsqualität. Schließlich wird eine simulationsbasierte Remote-Adaptable Prototype-in-the-Loop Methode im Kontext der gemischten Realität vorgestellt, die eine Lösung für schnelles und aufwandseffizientes Testen von kooperativen Fahrfunktionen bietet.

Incisional hernia is a frequent complication following loop ileostomy reversal. Incisional hernias are associated with morbidity, loss of health-related quality of life and costs and warrant the investigation of prophylactic measures. Prophylactic mesh implantation at the time of surgical stoma reversal has shown to be a promising and safe method to prevent incisional hernias in this setting. However, the efficacy of this method has not yet been investigated in a large multicentre randomised-controlled trial (RCT) with adequate external validity. The P.E.L.I.O.N. trial will evaluate the efficacy of prophylactic mesh reinforcement after loop ileostomy closure in decreasing the rate of incisional hernia versus standard closure alone.
