Bilateral thoracoscopic thymectomy using a novel positioning system.
2013
Several techniques of bilateral video-assisted thoracoscopic extended thymectomy have been proposed, and each has its own proponents. We summarize our experience in 20 patients who underwent bilateral video-assisted thoracoscopic extended thymectomy, using a new patient positioning that amplifies the thoracoscopic view of the cardiophrenic regions which are often difficult to visualize with standard techniques. In all cases, en-bloc thymectomy with complete dissection of the mediastinal fatty tissue was achieved without sternal retractors or additional incisions.
The use of video-assisted thoracic surgery in the management of Pancoast tumours
2010
We describe our experience using video-assisted thoracic surgery (VATS) as an adjunct to the surgical management of Pancoast tumors. Between March 2004 and November 2009, 13 patients with Pancoast tumors were included in this study. Surgery was performed by positioning the patient to allow either an anterior or a posterior thoracotomy. VATS was employed to explore the pleural cavity, to optimize the surgical access and as an assistance during surgical resection. Three patients with pleural carcinosis at thoracoscopy did not undergo further surgery. Seven lobectomies and three wedge resections were performed with an en bloc chest-wall resection and mediastinal lymphadenectomy. The surgical a…
Mild obstructive sleep apnoea: clinical relevance and approaches to management
2015
Summary Obstructive sleep apnoea is highly prevalent in the general population worldwide, especially in its mild form. Clinical manifestations correlate poorly with disease severity measured by the apnoea–hypopnoea index (AHI), which complicates diagnosis. Full polysomnography might be more appropriate to assess suspected mild cases because limited ambulatory diagnostic systems are least accurate in mild disease. Treatment options in mild obstructive sleep apnoea include continuous positive airway pressure (CPAP) and oral appliance therapy, in addition to positional therapy and weight reduction when appropriate. The superior efficacy of CPAP in reducing AHI is offset by greater tolerance of…
The da Vinci Xi Robotic Four-Arm Approach for Robotic-Assisted Minimally Invasive Esophagectomy
2018
AbstractRobotic surgery is gaining importance in complex thoracoscopic surgery, such as robotic-assisted minimally invasive esophagectomy (RAMIE). The RAMIE procedure was designed using the first generation of the robotic system. The latest da Vinci Xi system has substantially increased the dexterity, especially designed for multiquadrant surgery. The original three-arm RAMIE approach was modified including the robotic four-arm use for the thoracoscopic and laparoscopic part of the operation. This extended approach (four-arm RAMIE approach) provides more flexibility and raises the independence of the surgeon.
Performance assessment of PPP surveys with open source software using the GNSS GPS-GLONASS-Galileo constellations
2020
In this work, the performance of the multi-GNSS (Global Navigation Satellite System) Precise Point Positioning (PPP) technique, in static mode, is analyzed. Specifically, GPS (Global Positioning System), GLONASS, and Galileo systems are considered, and quantifying the Galileo contribution is one of the main objectives. The open source software RTKLib is adopted to process the data, with precise satellite orbits and clocks from CNES (Centre National d&rsquo
A new Multi-Layers Method to Analyze Gene Expression
2007
In the paper a new Multi-Layers approach (called Multi-Layers Model MLM) for the analysis of stochastic signals and its application to the analysis of gene expression data is presented. It consists in the generation of sub-samples from the input signal by applying a threshold technique based on cut-set optimal conditions. The MLM has been applied on synthetic and real microarray data for the identification of particular regions across DNA called nucleosomes and linkers. Nucleosomes are the fundamental repeating subunits of all eukaryotic chromatin, and their positioning provides useful information regarding the regulation of gene expression in eukaryotic cells. Results have shown a good rec…
Individual and Contextual Determinants of Cruise Passengers’ Behavior at Their Destination: A Survival Approach
2020
The proposed study will present an analysis of cruise passengers’ behavior at their destination. Mobility behavior will be analyzed in relation to socio-demographic characteristics through a survival modeling approach. Data collected through GPS devices on cruise passengers’ behavior in the ports of Palermo and Dubrovnik will be analyzed in order to determine similarities and differences among cruise passengers’ behaviors at their destination, according to socio-demographic characteristics. The authors of this chapter contend that the results of this research, involving the processing and the analysis of GPS data, will be of interest from methodological and destination management perspectiv…
Map of the visibility and search engine positioning of the main Spanish media groups
2020
Este trabajo analiza la visibilidad y posicionamiento en buscadores de los sitios web de los principales grupos de comunicación españoles. Se compara su visibilidad web y su presencia en los resultados de búsqueda de Google a través de programas de análisis SEO y una metodología propia que se ha denominado Índice de Visibilidad Agregada. Se ha realizado un análisis comparativo de los grupos Atresmedia, COPE, Godó, Hearst Magazines, Henneo, Imagina Media Audiovisual, Intereconomía Corporación, Joly, Mediaset España Comunicación, Planeta, Prensa Ibérica, Prisa, Unidad Editorial, Vocento y Zeta. Se ha podido establecer que Unidad Editorial es el grupo con mayor tráfico web proveniente de búsqu…
Use of CORS Time Series for Geodynamics Applications in Western Sicily (Italy)
2020
In the last few decades, the use of GNSS Continuously Operating Reference Station (CORS) networks allowed improving the accuracy of real-time positioning and post-processing positioning. In this way, several applications have been performed including remote sensing, agriculture, cultural heritage and geodynamics studies. The latter have been developed analysing CORS time-series and consistent data over long periods were needed to validate the results. In Italy, specifically in Sicily, two CORS networks were be used to monitor the geodynamics motions: the Istituto Nazionale di Geofisica e Vulcanologia (INGV) GNSS CORS network in the eastern part and the University of Palermo (UNIPA) GNSS COR…
EV-planning: Electric vehicle itinerary planning
2014
International audience; In the latest few years, lot of efforts have been done to pave the way to sustainable mobility, in order to solve pollution problems and fuel shortage. The use of electric vehicles (EV) is considered as one of the best ecologic and economic solution. However, autonomy barriers and limitations slow the progress and the deployment of this technology. In this paper, we propose an advanced electric vehicles' fleet management architecture. This architecture considers the most important factors that can affect the traveling mode of electric vehicles, in order to offer different services to fleet management companies for an efficient monitoring and management of their fleet…
