Next-generation three-dimensional modelling software for personalized surgery decision-making in perihilar cholangiocarcinoma: multicentre study
2021
Next-generation three-dimensional modelling software for personalized surgery allows spatially accurate depiction of the hepatic and vasculature anatomy based on the complexity and individual variation in each patient, and could facilitate decision-making about preoperative strategy in perihilar cholangiocarcinoma.
Medical simulation for ICU staff: does it influence safety of care?
2016
Dear Editor, We read with great interest the article by Garrouste-Orgeas et al. entitled ‘‘Understanding medical errors and adverse events in ICU patients’’ [1]. In particular, two sentences caught our attention: ‘‘medical errors are the consequence of multiple actions of a whole chain of organizational and humans interaction...’’ and ‘‘leadership, trust, respect, open communication, non-punitive actions and coordination of behavior are essential for a multidisciplinary ICU team to provide safe care’’. In a teamworking setting like the ICU, shared knowledge and non-technical skills are pivotal to deliver a high quality of care and to reduce medical errors. Medical simulation has been demons…

Comparative ergonomic workflow and user experience analysis of MRI versus fluoroscopy-guided vascular interventions: an iliac angioplasty exemplar ca…
2014
A methodological framework is introduced to assess and compare a conventional fluoroscopy protocol for peripheral angioplasty with a new magnetic resonant imaging (MRI)-guided protocol. Different scenarios were considered during interventions on a perfused arterial phantom with regard to time-based and cognitive task analysis, user experience and ergonomics. Three clinicians with different expertise performed a total of 43 simulated common iliac angioplasties (9 fluoroscopic, 34 MRI-guided) in two blocks of sessions. Six different configurations for MRI guidance were tested in the first block. Four of them were evaluated in the second block and compared to the fluoroscopy protocol. Relevant…
Theoretical approach and clinical application of kinetic modelling in dialysis.
1991
Using kinetic modelling for shaping profile dialysis, we present a promising approach to improve the cardiovascular stability of patients during dialysis treatment. In order to obtain an insight into the physiological mechanisms of increased stability, a model considering alterations of electrolytes and water distribution and of acid-base status was developed. This algorithm was used for the evaluation of 114 dialysis sessions, which were performed with highly individualised profiles. Each profile was developed for one patient by trying empirically to prevent episodes of hypotension as well as other clinical problems throughout dialysis. The main advantage of profile dialysis compared to st…
Software/Hardware Issues in Modelling Insect Brain Architecture
2011
The concept of cognitive abilities is commonly associated to humans and animals like mammals, birds and others. Nevertheless, in the last years several research groups have intensified the studies on insects that posses a much simpler brain structure even if they are able to show interesting memory and learning capabilities. In this paper a survey on some key results obtained in a joint research activity among Engineers and Neurogeneticians is reported. They were focussed toward the design and implementation of a model of the insect brain inspired by the Drosophila melanogaster. Particular attention was paid to the main neural centers the Mushroom Bodies and the Central Complex. Moreover a …
Analytical model for the long- distance tracer-transport in plants
2011
International audience; Recent investigations of long-distance transport in plants using non-invasive tracer techniques such as C radiolabeling monitored by positron emission tomography (PET) combined with magnetic resonance imaging (MRI) revealed the need of dedicated methods to allow a quantitative data analysis and comparison of such experiments. A mechanistic compartmental tracer transport model is presented, defined by a linear system of partial differential equations (PDEs). This model simplifies the complexity of axial transport and lateral exchanges in the transport pathways of plants (e.g. the phloem) by simulating transport and reversible exchange within three compartments using j…
Herramientas matemáticas para la valoración de la ampliación de una infraestructura portuaria
2003
infraestructura portuaria ya consolidada, que conlleva unas inversiones a largo plazo. Para ello hay que recurrir a medios de an´alisis capaces de recoger, en la medida de lo posible, la incertidumbre sobre la futura evoluci´on de los tr´aficos de mercanc´?as, sobre el efecto de la competencia entre puertos, etc., y que los m´etodos tradicionales no aproximan en toda su dimensi´on. Existe, adem´as, un problema de decisi´on de pol´?tica ´optima de gesti´on del proyecto que depende de variables de decisi´on que modelizan las opciones presentes en el mismo. Las oportunidades de inversi´on han sido tratadas como una colecci´on de opciones americanas sobre activos reales. Nosotros hemos optado p…
