Clinical Impact of Bioactive Substances in Blood Components: Implications for Leukocyte Filtration

Zusammenfassung Ziel: Übersichtsarbeit zu aktuellen Erkenntnissen über Nebenwirkungen von perioperativen Bluttransfusionen, insbesondere unter dem Aspekt der Bedeutung von leukozytären und thrombozytären bioaktiven Mediatoren. Vorschläge zur Herstellung von Blutkomponenten, um das Outcome von transfundierten Patienten zu verbessern. Quellen: Vorliegende Publikationen und Ergebnisse von eigenen experimentellen und klinischen Studien. Ergebnisse: Transfusionsassoziierte Nebenwirkungen bei der Gabe von Vollblut, plasmareduziertem Vollblut, Erythrozytenkonzentraten (SAGM), Thrombozytenund Plasmapräparaten werden häufig berichtet. Darüber hinaus stehen perioperative Bluttransfusionen im Zusammenhang mit erhöhter Inzidenz postoperativer Komplikationen und mit verminderter Rezidivfreiheit und Langzeitüberlebensrate nach potentiell kurativem Eingriff bei Krebserkrankung. Dieser Zusammenhang wird durch Daten unterstützt, die ein erhöhtes Krebserkrankungrisiko bei solchen Patienten zeigen, die Bluttransfusionen für benigne Erkrankungen erhielten. Nach derzeitigem Kenntnisstand sind diese Transfusionsnebenwirkungen unter anderem auf die Herstellungsverfahren, die Lagerungszeit, die Lagerungstemperatur, den zellulären Gehalt und den Gehalt an leukozytären und thrombozytären bioaktiven Mediatoren der Blutkomponenten und auch auf die Transfusionspraxis selbst zurückzuführen. Diese Erkenntnisse legen nahe, daß eine Leukozytendepletion die Qualität von Blutkomponenten und damit das Patienten-Outcome verbessert. Schlussfolgerungen: Transfusionsassoziierte Komplikationen und Nebenwirkungen scheinen von der Lagerungszeit und dem Gehalt an leukozytären und thrombozytären bioaktiven Mediatoren abhängig zu sein. Eine Leukozytendepletion verbessert potentiell das klinische Outcome der Patienten, doch der optimale Zeitpunkt und das vorteilhafteste Vorgehen bei der Leukozytendepletion sind noch nicht vollständig aufgeklärt.

La Técnica Mimética en Ausencia de Datos Originales: Aprendizaje y Revisión de Modelos

The mimetic technique (or Multiple Combined Models, CMM) basically consists of using a generally accurate but incomprehensible model as an oracle to generate and label a random data set. This dataset is used, along with the original training data, to train a second comprehensible model, known as the mimetic model. This technique has been used to provide understandability to black box models without considerably sacrificing their accuracy. In this work we study the mimetic application in a scenario in which the original training data is not available. In this context we first determine the optimal size of the random data set, according to the minimum message length principle (MML). This result can be used in knowledge acquisition for expert systems. Secondly we apply the mimetic technique to model revision and show that in some change situations the mimetic model can be used as a transition model between the original model and the new model.
A novel approach for real-time equivalent bandwidth estimation

In real-time multimedia applications, the delay is an important performance metric as well as packet loss probability (PLP). In this paper, based on their statistical characteristics and with the PLP and the delay considered, a computationally simple approximate expression for the equivalent bandwidth of multimedia applications, has been proposed for real-time bandwidth estimation and management. The impact of some relevant parameters have been investigated.

Sensorless Manipulation Using Transverse Vibrations of a Plate

The existing industrial parts feeders move the parts through a sequence of mechanical filters that reject parts in unwanted orientations. In this paper we develop a new setup that uses a different vibratory mechanism to systematically manipulate parts, by actively orienting and localizing them. The idea is to generate and change dynamic modes for a plate by varying the applied frequency of oscillation. Depending on the node shapes of the plate for these frequencies, the position and orientation of the parts can be controlled. We develop an analysis of the underlying dynamics, and show that it can be used to predict the behavior of objects placed on the vibrating plate. Using this analysis, we propose that the applied frequencies can be automatically sequenced to obtain a "sensorless" strategy for manipulating a given object.
Skin dose to patients from interventional radiology and cardiology procedures with potentially long fluoroscopy times

The increasing frequency and complexity of interventional procedures means that there is an increasing potential for the patient to suffer radiation-induced skin injuries. Dose measurements were initiated in a number of radiology, neuroradiology and cardiology departments in the Northern Ireland region which carry out interventional procedures with potentially long fluoroscopy times. The intention was to measure patient skin dose and thus estimate the likelihood of deterministic effects occurring from such examinations. For each patient, several thermoluminescence (TL) dosemeters were placed on the areas of skin the radiologist or cardiologist considered were most likely to receive the greatest irradiation. Results are presented which indicate that several types of procedure have the potential to produce deterministic effects to patients' skin. It was concluded that skin dose should be routinely measured for each patient undergoing an interventional radiology procedure which has potentially a long fluoroscopy time.
Estimation personnalisée de la dose après totalisation isotopique par l’131I chez un patient présentant un goitre endothoracique résiduel

Chez un patient ayant recu 3,7 GBq d’131 I apres thyroidectomie totale pour un carcinome papillaire, la mesure du debit de dose a 1 m, realisee de facon systematique 3 jours apres le traitement, a montre une valeur anormalement elevee. Une scintigraphie et une Tomographie d’Emission MonoPhotonique associee a une Tomodensitometrie (TEMP/TDM) ont alors ete realisees et ont montre une fixation importante de l’iode au niveau mediastinal anterieur due a la presence d’un goitre endothoracique residuel. Compte tenu de la proximite entre ce goitre iodofixant et les tissus avoisinants, les doses recues par les organes a risque les plus proches, notamment le cœur, ont ete evaluees. Cette evaluation a ete realisee, dans un premier temps, avec le logiciel OLINDA/EXM, couramment utilise en medecine nucleaire. Des doses plus personnalisees ont ensuite ete calculees a l’aide du logiciel OEDIPE associe au code Monte Carlo MCNPX. Les calculs effectues avec le logiciel OLINDA/EXM ont permis d’evaluer la dose moyenne absorbee au cœur a environ 2 Gy avec une fixation de 56 % de l’activite administree. Dans un second temps, l’utilisation du logiciel OEDIPE a permis de prendre en compte la geometrie specifique du patient ainsi que la repartition de la fixation d’iode au niveau mediastinal et de determiner une dose absorbee moyenne d’environ 1 Gy au cœur. Ainsi, l’utilisation d’un fantome voxelise, base sur les images TDM du patient, associe a un calcul Monte Carlo direct a permis d’optimiser le calcul des doses absorbees au cœur par rapport a l’utilisation d’un fantome anthropomorphe standard.
Perfil lingüístico del individuo con síndrome de Asperger:: implicaciones para la investigación y la práctica clínica

Objetivo. Realizar una revision selectiva de los trabajos dirigidos al estudio del perfil de habilidades linguisticas y de comunicacion del individuo afectado por el sindrome de Asperger (SA). Desarrollo. Todos los trabajos revisados aportan datos consistentes con la existencia de un perfil linguistico particular asociado al SA, que se caracteriza por presentar areas de competencias significativas con respecto a la adquisicion de los elementos formales y estructurales del lenguaje, asi como areas de deficit pronunciados en el desarrollo de las habilidades pragmaticas y adquisicion de especificos componentes semanticos. Conclusiones. La alteracion de las habilidades pragmaticas o de la comunicacion social se observa en todos los individuos afectados por el SA y, en consecuencia, constituye un rasgo nuclear del cuadro sintomatico del trastorno. Los estudios revisados senalan la relevancia de la identificacion del perfil linguistico en tanto que puede facilitar el establecimiento del diagnostico del SA y contribuir a precisar los limites de diferenciacion no solo con otros trastornos generalizados del desarrollo, sino con otros trastornos psiquiatricos que presentan un solapamiento sintomatico. Aunque los trabajos analizados no aportan datos precisos sobre los mecanismos patologicos especificos subyacentes a la constelacion de los deficit pragmaticos asociados al SA, si proporcionan una cierta evidencia sobre la relacion entre los deficit pragmaticos y una disfuncion del hemisferio cerebral derecho.
Adenoma oncocítico de tiroides (adenoma de células de Hürthle). Revisión del espectro morfológico a propósito de cuatro casos

El cambio oncocitico es un agrandamiento del citoplasma ocasionado por la acumulacion de mitocondrias, que se presenta en una amplia variedad de condiciones reactivas y neoplasicas. En la glandula tiroides, dicho cambio es un fenomeno de metaplasia que ocurre en distintas situaciones que provocan estres celular y en ocasiones da lugar a verdaderas neoplasias benignas y malignas, entre las que destaca el adenoma oncocitico. A proposito de cuatro casos estudiados en el Departamento de Patologia del Hospital ABC con caracteristicas citomorfologicas inusuales que representaron un reto diagnostico, hacemos una revision del espectro morfologico de estos tumores. Las caracteristicas presentadas incluyeron necrosis isquemica masiva posterior a toma de biopsia por aspiracion, tamano mayor al esperado en un adenoma, coexistencia con una neoplasia maligna independiente y caracteristicas histologicas similares a las observadas en carcinoma papilar. Es de gran importancia para el patologo conocer estas caracteristicas, para evitar errores diagnosticos que puedan implicar un inadecuado manejo terapeutico

Towards Knowledge-driven QoE Optimization in Home Gateways

The growth of broadband Internet access across the world for the last 10 years has made new business models possible. Services which before mainly were provided by network operators and in dedicated networks have now migrated to the open Internet. This has created a global service provider market, using the Internet as platform. The network operators are in many cases left with only providing the broadband access service. For the global service providers, continuous effort is put into the field of finding smart methods for bringing new and advanced services to the market without asking for e.g. QoS features from the involved network operators. This type of service delivery is called Over-The-Top (OTT). The concept of making services able to adapt their network and transport requirements during time of delivery is a strong contribution to success for OTT services.The focus of the work in this thesis, is methods for improving various aspects - as defined by my research questions - related to QoS and potentially also QoE for dynamic adaptive video streaming over HTTP (DASH) services. The motivation for focusing on video services is based on their high QoS requirements (i.e. bandwidth) and also popularity in terms of usage.In the work presented in this thesis, I have studied the behaviour and performance of DASH services by means of simulations, measurements and experiments. Based on insight obtained through this, I established a hypothesis on how QoS and QoE aspects could be improved for users present in the same home network environment. My hypothesis was that making more accurate information available about both services and network conditions in near real-time could facilitate improved control methods. The effectiveness of my suggested methods have in most cases been analysed by means of implementation in an experimental lab scenario, and supported by simulations and analytical approaches when appropriate.The findings presented in the included papers are all closely related and map into the research model used. This model is composed of Knowledge Plane, Monitor Plane and Action plane components located in both service endpoints and involved network components. As my main focus has been on OTT service delivery, the main contributions of my work apply to service endpoints, i.e. components in the home network and on the server side. The server side would in many cases be represented by a Content Delivery Network (CDN) node.The main research questions identified are:RQ1: In a home network how to (autonomously) control the performance of DASH based services.RQ2: How to provide fairness and stability for competing DASH sessions using service endpoint functionality.RQ3: How to choose appropriate quality levels for a DASH session.The main contributions from my research are:C1: A method for controlling the quality levels of DASH in the home gateway.C2: A method for improving fairness among competing DASH sessions.C3: A method for shaping traffic aggregates on access links with DASH components.C4: A method for estimating available bandwidth on access links when DASH sessions are present.
Preventing CMV Viremia and Disease 3–6 Months After Renal Transplantation

The letter by Mossad et al. raises some important issues regarding strategies for preventing CMV disease occurring after completion of antiviral prophylaxis (i.e. lateonset CMV). It is correct that in the IMPACT trial, for patients receiving 100 days of prophylaxis, the majority of late-onset disease occurred between month 3 and month 6 posttransplant (1). I agree that routine virologic monitoring after completing 100 days of prophylaxis (a hybrid prophylaxis/pre-emptive strategy) may be an alternative prevention approach (vs prolongation of prophylaxis). However, based on the current literature it is unclear what the comparative efficacy of this would be for the prevention of late-onset disease. In one study analyzing the potential value of such a strategy after completing of a 3 month course of antiviral prophylaxis, routine viral load monitoring would have predicted late-onset disease in only 24/64 (38%) cases (2). Since in vivo viral doubling time may be quite rapid in high-risk transplant patients (in the range of 1–2 days) (3), it may be that more intensive viral load monitoring (e.g. weekly) would be required in order to prove effective in preventing disease. Such intensive monitoring may be logistically difficult in some settings once patients are beyond 3 months posttransplant.

CDMA/TDD cellular systems for the 3rd generation mobile communication

We propose CDMA/TDD cellular systems utilizing a base-station-based diversity scheme. A significant reduction in the required Eb/No resulting from the use of a hybrid diversity scheme combining the effects of space diversity and path diversity is shown. Because TDD uses only one radio frequency band and transmission diversity at the base station can be employed, space diversity is unnecessary at the mobile station and thus the mobile station can be made smaller. CDMA/TDD systems can also realize effective transmission power control with only the use of open-loop control. A single antenna and no duplexer are advantageous in CDMA/TDD for terminal size and battery life. This system is especially effective in an environment such as microcellular systems or indoor office systems where the spreading bandwidth is narrower than the coherent bandwidth, and path diversity gain by itself is small.
Robust control for hydraulic power plants

An automatic control procedure for hydraulic plants in series which not only avoids a continuous human presence in the power plants, but also makes it possible to obtain improved performance in the operating system, is described. The algorithms and the determination of control parameters employ improved software codes which make it possible to optimize the control system for a wide range of operating regimes and flow rates, so stability and security are enhanced. The realization of such centralized control stations allows not only the rationalization and optimization of water management at the level of a cascade of power plants, but also the easing of operating critical conditions as floods control. <<ETX>>
