Is laser-assisted resection preferable to lobectomy for pulmonary metastasectomy?

Purposes. The aim of this study was to investigate if laser-assisted resection is appropriate for large and/or central lung metastases, when stapler wedge resection is not feasible, to determine whether this technique can be an alternative to lobectomy. Methods. All patients who underwent laser-assisted resection for large and/or central metastases were selected for the study. For comparison, patients who underwent lobectomy for metastases between 2005 and 2017 were reviewed. All resections were performed with a 1318-nm Nd:YAG laser. Perioperative features and long-term oncological outcomes were investigated. Some aspects and drawbacks of laser resection were also investigated. Results. Among 89 patients, 42 (47%) underwent laser resection and 47 underwent lobectomy. Complete resection was achieved in 91% of laser resections and in 98% of lobectomies. The operative time, postoperative drainage time and length of stay were significantly shorter in patients who underwent laser resection than in those who underwent lobectomy. Severe postoperative complications tended to be more frequent after lobectomy. The 5-year survival was 66% and 54% after laser resection and lobectomy respectively, the 5-year disease-free survival was 35% and 32% after laser resection and lobectomy respectively. No differences were found in long-term outcomes between the two techniques. Conclusions. Our experience showed that laser resection, when performed for large/central metastases, resulted in comparable survival and obtained better perioperative outcomes with respect to lobectomy. We believe that laser resection can be proposed as a reliable and advantageous lung-sparing technique, as an alternative to lobectomy for metastasectomy, when stapler wedge resection is not feasible

Intersatellite link for Earth Observation Satellites constellation

This paper is devoted to investigate the possibility to implement a data Intersatellite Link between satellites of an Earth Observation constellation and a dedicated TLC GEO satellite. An EO system is mainly composed of two segments (space and ground) connected by a complex network of communications that permits to manage the operations of the constellation. Due to the high performances in terms of imaging capabilities of the radar/optical payloads a corresponding high capacity to download data to ground is needed. To guarantee that the system is able to download to the ground station, in a proper time, all the images taken from the radar during the mission, external ground stations, located in a polar zone, have to be foreseen. Polar stations offer a service needed to provide the requested images to the users in a near real-time manner. In this paper an alternative approach, using an Intersatellite link system (ISLs) instead of polar stations, is presented. The most relevant trade-offs from technical point of view have been addressed. The purposes of this activities is to demonstrate the capability of a high speed two way optical link, between LEO and GEO terminals, with a bit rate in the order to 2.5 Gbps in the frame of satellites constellation. This implementation should permit to avoid the use of polar stations ensuring in the same time the achievement of high system time performances, in an operational cost-saving approach

Il danno indiretto

Il capitolo, inserito nella sezione dedicata alle fattispecie di responsabilità amministrativo-contabile, descrive analiticamente gli elementi costitutivi del danno erariale indiretto e le questioni problematiche sollevate dall'istituto. In particolare si ricostruiscono i rapporti tra giudizio risarcitorio in sede ordinaria e azione di rivalsa contabile, compresa la possibilità di utilizzare le prove raccolte nel primo giudizio all'interno del secondo, la possibile concorrenza della rivalsa civilistica e dell'azione di responsabilità amministrativa e la querelle giurisprudenziale sul dies a quo di decorrenza del termine di prescrizione dell'azione innanzi alla Corte dei conti, offrendo soluzioni precarie ma possibilmente innovative ai profili critici ancora insoluti
