Diagnosis and management of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is probably one of the most prevalent diseases in the world that also compromises the quality of life of the affected significantly. Its incidence in Brazil is 12%, corresponding to 20 million individuals. OBJECTIVE: To update the GERD management and the new trends on diagnosis and treatment, reviewing the international and Brazilian experience on it. METHOD: The literature review was based on papers published on Medline/Pubmed, SciELO, Lilacs, Embase and Cochrane crossing the following headings: gastroesophageal reflux disease, diagnosis, clinical treatment, surgery, fundoplication. RESULTS: Various factors are involved on GERD physiopathology, the most important being the transient lower esophageal sphincter relaxation. Clinical manifestations are heartburn, regurgitation (typical symptoms), cough, chest pain, asthma, hoarseness and throat clearing (atypical symptoms), which may be followed or not by typical symptoms. GERD patients may present complications such as peptic stenosis, hemorrhage, and Barrett's esophagus, which is the most important predisposing factor to adenocarcinoma. The GERD diagnosis must be based on the anamnesis and the symptoms must be evaluated in terms of duration, intensity, frequency, triggering and relief factors, pattern of evolution and impact on the patient's quality of life. The diagnosis requires confirmation with different exams. The goal of the clinical treatment is to relieve the symptoms and surgical treatment is indicated for patients who require continued drug use, with intolerance to prolonged clinical treatment and with GERD complications. CONCLUSION: GERD is a major digestive health problem and affect 12% of Brazilian people. The anamnesis is fundamental for the diagnosis of GERD, with special analysis of the typical and atypical symptoms (duration, intensity, frequency, triggering and relief factors, evolution and impact on the life quality). High digestive endoscopy and esophageal pHmetry are the most sensitive diagnosctic methods. The clinical treatment is useful in controlling the symptoms; however, the great problem is keeping the patients asymptomatic over time. Surgical treatment is indicated for patients who required continued drug use, intolerant to the drugs and with complicated forms of GERD.

Interventi normativi, interni ed uniformi, dettati dalle nuove esigenze e dai nuovi quesiti posti dalla modernizzazione dei traffici, con particolare riferimento al trasporto containerizzato e multimodale

Come si evince dal titolo della tesi, la ricerca effettuata dal presente candidato nel corso del dottorato di ricerca ha avuto ad oggetto lo studio della materia relativa ai trasporti nell’ambito di diversi sistemi giuridici europei, con particolare attenzione ai risvolti di carattere pratico che l’interpretazione delle normative uniformi poteva produrre nell’ambito delle diverse giurisdizioni nonché alle diverse impostazioni e alla variegata gamma di soluzioni interpretative che nell’ambito di problemi simili possono essere adottate a seconda che una stessa questione venga discussa in un ordinamento piuttosto che in un altro. Dall’avvento del trasporto marittimo di containers alla necessità di disciplinare l’intera materia attraverso una normativa multimodale il passo è estremamente breve, posto che, proprio in considerazione delle caratteristiche proprie del trasporto containerizzato, gli aventi diritto al carico sono principalmente interessati al completamente del trasferimento door-to-door inteso nella sua globalità, piuttosto che al buon esito del trasporto sulla singola tratta marittima. Il progetto di revisione delle Regole dell’Aja-Visby adottato dall’United Nations Commission on International Trade Law (Uncitral) e il Comité Maritime International (CMI) costituisce per definizione un progetto limitato ad un trasporto multimodale comprendente necessariamente una tratta marittima, ma rappresenta comunque un interessante banco di prova per valutare la funzionalità di strumenti di recente impiego, come ad esempio i cosiddetti e-documents, concetto peraltro già inserito nel progetto UNCITRAL, anche se con scarsi elementi di reale novità rispetto alla tradizionale disciplina relativa ai documenti cartacei. Proprio la parte relativa ai documenti e titoli di viaggio merita particolare attenzione soprattutto in riferimento alle problematiche connesse al traffico containerizzato, con particolare riferimento al concetto di transhipment, e alla conseguente necessità che la polizza garantisca al legittimo portatore una copertura completa sull’intero viaggio della merce, oltre a dargli la possibilità di individuare agevolmente la propria controparte contrattuale, e cioè il vettore.

Nuove pratiche turistiche e sostenibilita'. I profili del turista lento in Valnerina

Il presente lavoro intende analizzare il tema del turista lento che nell’ultimo decennio si è diffuso nel dibattito scientifico e culturale connesso al tema della sostenibilità e della qualità della vita e nel contesto dell’approccio teorico strutturato intorno alle nuove tendenze dello Slow Tourism. In una prima parte la tesi delinea il framework della sostenibilità con particolare attenzione al recente dibattito in corso sulla “decrescita” e l’“a-crescita” come concetti alternativi al paradigma della crescita. Successivamente viene evidenziato il modo in cui le idee di base ed i principi dello sviluppo sostenibile sono stati applicati al turismo e indagato il legame tra sostenibilità e responsabilità e come questo configura l’emergere di un turismo “responsustable”. In tale contesto viene analizzata la relazione tra turismo e lentezza in cui a filosofia slow non deve essere interpretata come un fenomeno del momento o un innovativo prodotto turistico, ma come una filosofia di vita, un movimento sociale e globale che negli ultimi anni ha caratterizzato i diversi ambiti socio-economici delle comunità locali. Successivamente attraverso una review della letteratura nazionale ed internazionale sul tema, la pluralità di prospettive teoriche vengono sistematizzate in tre ipotesi di lettura riconducibili a tre paradigmi: sostenibilità- slow tourism- territorio; benessere – slow tourism – qualità della vita; esperienza – slow tourism – consumo. Nella seconda parte del lavoro viene presentata l’indagine empirica a partire dall’analisi di contesto del territorio in cui si è svolta l’attività di ricerca, i nove comuni del Comprensorio Turistico della Valnerina in Umbria, con particolare riferimento all’analisi dell’offerta e della domanda turistica. Successivamente sono presentati i risultati di un questionario somministrato a 620 turisti attraverso il quale viene analizzato il profilo motivazionale, le esperienze di fruizione turistica e la percezione della qualità territoriale da parte del turista e delineato il profilo del turista slow in Valnerina.

Distance education in transition

In his most recent publication, Against the Tide: Critics of Digitalisation, Otto Peters brings together some of the most formidable and critical voices and compelling perspectives on the potential hazards of digitalization. The viewpoints presented range from personal, anthropological, and pedagogical to more scientific and technical, and arise from multiple disciplines. Peters has long been a respected scholar in the field of distance education, and while Peters’ earlier work has advocated the affordances of digitalization, this latest book is an abrupt shift to the darker side of digitalization. The assembly of critics Peters has gathered come from around the world and different walks of life: journalists, educators, scientists, philosophers, lawyers, mathematicians, and computer scientists, to name a few. Their one shared bond is a deep-seated belief that digitalization will have a profound and lasting impact on humankind – and not only in positive ways. ...

Image-Guided Otorhinolaryngology

Beginning with a brief historical background, the chapter then offers the reader a practical overview of established procedures using image-guided surgery (IGS) in otorhinolaryngology. American and European recommendations for the use of IGS already exist and will be critically discussed in the light that a skilled hand and detailed knowledge of the anatomy by an experienced surgeon cannot yet be replaced by technology alone. Finally, a selected sample of new trends of experimental applications of intraoperative imaging and image-guided therapy will be given.

Dish Detection and Segmentation for Dietary Assessment on Smartphones

Diet-related chronic diseases severely affect personal and global health. However, managing or treating these diseases currently requires long training and high personal involvement to succeed. Computer vision systems could assist with the assessment of diet by detecting and recognizing different foods and their portions in images. We propose novel methods for detecting a dish in an image and segmenting its contents with and without user interaction. All methods were evaluated on a database of over 1600 manually annotated images. The dish detection scored an average of 99% accuracy with a .2s/image run time, while the automatic and semi-automatic dish segmentation methods reached average accuracies of 88% and 91% respectively, with an average run time of .5s/image, outperforming competing solutions.

Desarrollos y tejidos actuales en el campo de la tecnología educativa : Caleidoscopio en movimiento

El artículo propone algunas construcciones analíticas que articulan perspectivas actuales y que ofrecen pistas para repensar la enseñanza y el aprendizaje cuando hay mediación tecnológica. A partir de un breve recorrido por el campo de la Tecnología Educativa desde sus orígenes a la actualidad, se centra en tres "tejidos" (en tanto articuladores de ideas). El primero da cuenta de una perspectiva cognitiva y refiere a la mente participativa como constructo que ofrece un prisma para comprender la cognición en tiempos de redes sociales; el segundo, centrado en la enseñanza recupera la idea de la reconstrucción del aprendizaje experiencial; el último aborda la tendencia en las formas de producción. Estas tres tendencias conforman un "caleidoscopio" que ofrece una desmitificación de la relación entre tecnología e innovación y entre tecnología y motivación y una perspectiva más compleja para generar cambio educativo.

Gaussian Multiscale Aggregation oriented to Hand Biometric Segmentation in Mobile Devices

New trends in biometrics are oriented to mobile devices in order to increase the overall security in daily actions like bank account access, e-commerce or even document protection within the mobile. However, applying biometrics to mobile devices imply challenging aspects in biometric data acquisition, feature extraction or private data storage. Concretely, this paper attempts to deal with the problem of hand segmentation given a picture of the hand in an unknown background, requiring an accurate result in terms of hand isolation. For the sake of user acceptability, no restrictions are done on background, and therefore, hand images can be taken without any constraint, resulting segmentation in an exigent task. Multiscale aggregation strategies are proposed in order to solve this problem due to their accurate results in unconstrained and complicated scenarios, together with their properties in time performance. This method is evaluated with a public synthetic database with 480000 images considering different backgrounds and illumination environments. The results obtained in terms of accuracy and time performance highlight their capability of being a suitable solution for the problem of hand segmentation in contact-less environments, outperforming competitive methods in literature like Lossy Data Compression image segmentation (LDC).

Contribución a las nuevas tendencias en el diseño de tuberías en construcción naval

En la situación actual, tanto las posibilidades de contratar como los resultados económicos de un astillero, dependen de su capacidad para construir un buque en el plazo mas corto posible. Dentro de los trabajos de diseño y construcción de de un buque el trabajo de tuberías ha sido el que tradicionalmente ha condicionado los plazos de construcción. En este estudio se considerara que se han tenido en cuenta los criterios necesarios para que las instalaciones del buque funcionen correctamente y se verá como los sistemas de diseño influyen en el coste y plazo del buque y, por tanto, en la productividad del astillero. Se estudian los distintos procesos de diseño, fabricación y montaje de tuberías, la evolución de estos procesos a lo largo del tiempo, los módulos de armamento que se realizan en los astilleros, los modelos de cámara de máquinas, y los sistemas de ayuda al diseño por ordenador. El autor, en su puesto de Jefe de la Oficina Tecnológica de la Factoría de Sevilla de Astilleros Españoles en los últimos 12 años, ha tomado parte activa en esta evolución, formando parte de un equipo que ha situado a este astillero entre los mas avanzarlos de Europa. Todo lo anterior sirve de base para la segunda parte de este estudio, donde se abordan las que, en opinión del autor, son las nuevas tendencias en el diseño de tuberías en la construcción naval. V Integración del CAD/CAM o CIM : CAD = computer aided design o diseño asistido por ordenador, CAM = computer aided manufacturing o fabricación asistida por ordenador, CIM = computer integrated manufacturing o fabricación integrada por ordenador. Se estudia la integración de los procesos de diseño con el resto de los procesos de gestión y de producción de un astillero, proponiéndose un modelo de cómo el autor ve esta integración. Se comenta la actual tendencia a pasar de las automatizaciones duras con maquinas especializadas para cada proceso, a las automatizaciones blandas en las que un robot puede realizar distintos procesos modificando su programación. Se estudian las nuevas posibilidades de la normal i zacio'n, de los planos parametrizados y de la tecnología de grupos aportando algunos ejemplos. Se estudia también como los procesos anteriores conducirán a una optimización del producto en sí, es decir a conseguir mejores buques. En las conclusiones destacamos como el camino que tienen los países desarrollados, como el nuestro, para mantener una industria competitiva de construcción naval va por la mecanización de los procesos constructivos siguiendo las tendencias anteriores y obteniendo buques optimizados. vi SUMMARY Under the present situation the possibilities to contract and the economical results of a Shipyard depend on its capacity to build a ship within the shortest time. i Within the works of design and construction of a ship, piping work has traditionally conditioned the construction time. In this study it shall be considered that the necessary criteria for the ship installations to operate correctly have been taken into account and it shall be noticed how the design systems influence on the cost and time of a ship and therefore on the Shipyard's productivity. Studies are made of different design processes, manufacturing and installation of piping, evolution of these processes along the time, outfitting modules made in the Shipyard, engine room models and computerized design aid systems. The author, in his post of Chief of the Technological Office of Sevilla Shipyard of Astilleros Españoles for the last 12 years, has taken an active part in this evolution, making part of a team which has placed this Shipyard among the most advanced in Europe. All of the above is used for the second part of this study, whereby an approach is made to those who, in the author's opinion, are the new trends in the piping design of shipbuilding. vii Integration of CAD/CAM or CIM: CAD = computer aided design, CAM = computer aided manufacturing, CIM = computer integrated manufacturing. i A study is made of the integration of design processes with the remaining step and production Shipyard processes, proposing a model of how the author views this integration. Comments are made on the present trend to go from hard automations with specialized machines for each process to soft automations, in which a robot can carry out different processes modifying its programmes. Studies are made of: New possibility of standardization, parametrized drawings and group technology, bringing some examples. It is also studied how the above processes shall lead to optimize the product itself, that is, to obtain better ships. In the conclusions we stand out how the way of developed countries (as ours) to maintain a competitive shipbuilding industry is by computerizing constructive processes, following the above trends and obtaining better ships.
