A pilot study to evaluate the self-medication system for liver transplant patients at the Queen Elizabeth Hospital in Birmingham

Background and Objective: Medication non-compliance is a considerable obstacle in achievinga therapeutic goal, whichcan result in poorerhealthcare outcomes, increased expenditure, wastage and potential for medication resistance. The UK Government’s Audit Commission’s publication ‘A Spoonful of Sugar’1 addresses these issues and promotes self-medication systems as a possible solution. The self-medication system within the Liver Transplant Unit (LTU) was implemented to induct patients onto new post- transplantation medication regimes ready for discharge. The system involves initial consultations with both the Liver Transplant Pharmacist and Trans- plant Co-ordinator, supported with additional advice as and when necessary. Design: Following ethical approval, evaluation of the self-medication sys- tem for liver transplant patients was conducted between January and March 2004 via two methods: audit and structured post-transplantation interview. The audit enabled any discrepancies between current Hospital guidelines and Liver Transplant Unit (LTU) practices to be highlighted. Patient interviews generated a retrospective insight into patient acceptance of the self-medication system. Setting: LTU, Queen Elizabeth Hospital, Birmingham, England. Main Outcome Measures: LTU compliance with Hospital self-medication guidelines and patient insight into self-medication system. Results: A total of seven patients were audited. Findings illustrated that self- medication by transplant patients is a complex process which was not fully addressed by current Hospital self-medication guidelines. Twenty-three patients were interviewed, showing an overwhelming positive attitude to- wards participating in their own care and a high level of understanding towards their individual medication regimes. Following a drugs counselling session, 100% of patients understood why they were taking their medica- tion, and their doses, 95% understood how to take their medication and 85% were aware of potential side effects. Conclusions: From this pilot evaluation it can be stated that the LTU self-medication system is appreciated by patients and assists them in fully understanding their medication regimes. There appear to be no major defects in the system. However areas such as communication barriers and on-going internet education were illustrated as areas for possible future investigation.

Estratégias distribuídas para a coexistência de redes de banda larga sem fio em bandas não-licensiadas

The increasing demand for Internet data traffic in wireless broadband access networks requires both the development of efficient, novel wireless broadband access technologies and the allocation of new spectrum bands for that purpose. The introduction of a great number of small cells in cellular networks allied to the complimentary adoption of Wireless Local Area Network (WLAN) technologies in unlicensed spectrum is one of the most promising concepts to attend this demand. One alternative is the aggregation of Industrial, Science and Medical (ISM) unlicensed spectrum to licensed bands, using wireless networks defined by Institute of Electrical and Electronics Engineers (IEEE) and Third Generation Partnership Project (3GPP). While IEEE 802.11 (Wi-Fi) networks are aggregated to Long Term Evolution (LTE) small cells via LTE / WLAN Aggregation (LWA), in proposals like Unlicensed LTE (LTE-U) and LWA the LTE air interface itself is used for transmission on the unlicensed band. Wi-Fi technology is widespread and operates in the same 5 GHz ISM spectrum bands as the LTE proposals, which may bring performance decrease due to the coexistence of both technologies in the same spectrum bands. Besides, there is the need to improve Wi-Fi operation to support scenarios with a large number of neighbor Overlapping Basic Subscriber Set (OBSS) networks, with a large number of Wi-Fi nodes (i.e. dense deployments). It is long known that the overall Wi-Fi performance falls sharply with the increase of Wi-Fi nodes sharing the channel, therefore there is the need for introducing mechanisms to increase its spectral efficiency. This work is dedicated to the study of coexistence between different wireless broadband access systems operating in the same unlicensed spectrum bands, and how to solve the coexistence problems via distributed coordination mechanisms. The problem of coexistence between different networks (i.e. LTE and Wi-Fi) and the problem of coexistence between different networks of the same technology (i.e. multiple Wi-Fi OBSSs) is analyzed both qualitatively and quantitatively via system-level simulations, and the main issues to be faced are identified from these results. From that, distributed coordination mechanisms are proposed and evaluated via system-level simulations, both for the inter-technology coexistence problem and intra-technology coexistence problem. Results indicate that the proposed solutions provide significant gains when compare to the situation without distributed coordination.

Caratterizzazione sperimentale di sistemi di localizzazione a banda ultra-larga

Il processo di localizzazione risponde all'esigenza dell'uomo di avere una percezione sempre più dettagliata e precisa del contesto in cui si trova, con l'intento di migliorare e semplificare l'interazione con oggetti e cose ivi presenti. L'idea attuale è quella di progettare sistemi di posizionamento con particolare riguardo agli ambienti indoor, caratterizzati da proprietà e densità di elementi che limitano fortemente le prestazioni dei consolidati sistemi di tracking, particolarmente efficienti in spazi aperti. Consapevole di questa necessità, il seguente elaborato analizza le prestazioni di un sistema di localizzazione sviluppato dall'Università di Bologna funzionante in tecnologia Ultra-Wide Bandwidth (UWB) e installato nei laboratori DEI dell'Alma Mater Studiorum con sede a Cesena. L'obiettivo è quello di caratterizzare l'accuratezza di localizzazione del sistema, suggerendo nuovi approcci operativi e de�finendo il ruolo dei principali parametri che giocano nel meccanismo di stima della posizione, sia in riferimento a scenari marcatamente statici sia in contesti in cui si ha una interazione dinamica degli oggetti con lo spazio circostante. Una caratteristica della tecnologia UWB è, infatti, quella di limitare l'errore di posizionamento nel caso di localizzazione indoor, grazie alle caratteristiche fisiche ed elettriche dei segnali, aprendo nuovi scenari applicativi favorevoli in termini economici, energetici e di minore complessità dei dispositivi impiegati.

Distribution, density and abundance of Antarctic ice seals off Queen Maud Land and the eastern Weddell Sea

The Antarctic Pack Ice Seal (APIS) Program was initiated in 1994 to estimate the abundance of four species of Antarctic phocids: the crabeater seal Lobodon carcinophaga, Weddell seal Leptonychotes weddellii, Ross seal Ommatophoca rossii and leopard seal Hydrurga leptonyx and to identify ecological relationships and habitat use patterns. The Atlantic sector of the Southern Ocean (the eastern sector of the Weddell Sea) was surveyed by research teams from Germany, Norway and South Africa using a range of aerial methods over five austral summers between 1996-1997 and 2000-2001. We used these observations to model densities of seals in the area, taking into account haul-out probabilities, survey-specific sighting probabilities and covariates derived from satellite-based ice concentrations and bathymetry. These models predicted the total abundance over the area bounded by the surveys (30°W and 10°E). In this sector of the coast, we estimated seal abundances of: 514 (95 % CI 337-886) x 10**3 crabeater seals, 60.0 (43.2-94.4) x 10**3 Weddell seals and 13.2 (5.50-39.7) x 10**3 leopard seals. The crabeater seal densities, approximately 14,000 seals per degree longitude, are similar to estimates obtained by surveys in the Pacific and Indian sectors by other APIS researchers. Very few Ross seals were observed (24 total), leading to a conservative estimate of 830 (119-2894) individuals over the study area. These results provide an important baseline against which to compare future changes in seal distribution and abundance.

Terrorismo perpetrado por la banda terrorista ETA vs. delitos de lesa humanidad

El 27 de octubre de 2015, el Juzgado Central de Instrucción número tres de la Audiencia Nacional (AN), procesó a cinco dirigentes etarras a los que considera responsables de un delito de lesa humanidad tipificado en el artículo 607 bis del vigente CP, en concurso real con delitos de asesinato. La causa se centra en los atentados mortales perpetrados por ETA a partir del 1 de octubre de 2004, fecha en la que se introdujo el delito de lesa humanidad en el CP español. En este trabajo se analizan los conceptos de terrorismo y delitos de lesa humanidad, con la finalidad de intentar aclarar la controversia suscitada, centrándose principalmente en establecer si los atentados cometidos por la banda terrorista ETA pueden tipificarse como delitos de lesa humanidad, y en caso afirmativo, desde qué fecha. Además contiene un apartado dedicado a las víctimas, que incluye una entrevista realizada a D. Daniel Portero de la Torre, presidente de la Asociación “Dignidad y Justicia”.

Reconstrucción mínimamente invasiva de la banda oblicua distal. Estudio anatómico

La radioulnar distal es una articulación diartrodial trocoide compuesta por la escotadura sigmoidea del radio y la cabeza ulnar. Su estabilidad depende de la integridad de diversas estructuras como son el complejo fibrocartílago triangular o CFCT, el músculo pronador cuadrado y el músculo extensor ulnar del carpo y la porción distal de la membrana interósea (MIO), fundamentalmente la banda oblicua distal, en los casos en los que se encuentra presente. La banda oblicua distal (BOD) es una estructura independiente de la porción membranosa distal de la membrana interósea la cual ha sido descrita en un 40% de los individuos. Se origina en 1/6 distal de la diáfisis ulnar y se inserta en el borde inferior de la escotadura sigmoidea. Algunas fibras se extienden más distalmente, pareciendo mantener continuidad con los ligamentos radioulnares dorsal y palmar, lo que ha hecho pensar en su función como estabilizador de la articulación radioulnar distal. A su vez, su inserción ulnar coincide con el eje de rotación del antebrazo, experimentando así pocos cambios durante la pronosupinación, comportándose de forma isométrica. El CFCT es el estabilizador primario de la articulación, y en situaciones normales la influencia de la porción distal de la membrana interósea es insustancial. Sin embargo, tras una lesión del fibrocartílago triangular o una resección de la cabeza ulnar, es cuando adquiere un papel fundamental...
