The RAGE Exploitation Plan is a living document, to be upgraded along the project lifecycle, supporting RAGE partners in defining how the results of the RAGE RIA will be used both in commercial and non-comercial settings. The Exploitation Plan covers the entire process from the definition of the business case for the RAGE Ecosystem to the creation of the sustainability conditions for its real-world operation beyond the H2020 project co-funding period. The Exploitation Plan will be published in three incremental versions, due at months 18, 36 and 42 of the project lifetime. This early stage version 1 of 3 is mainly devoted to: i. Setting-up the structure and the initial building blocks to be populated and completed in the future editions of the Exploitation Plan and to ii. providing additional guidance for market intelligence gathering, business modelling definition and validation, outreach and industry engagement and ultimately providing insights for the development, validation and evaluation of RAGE results across the project´s workplan execution. These tasks will in turn render suitable inputs to enhance the two future editions of the Exploitation Plan.

We know now from radial velocity surveys and transit space missions thatplanets only a few times more massive than our Earth are frequent aroundsolar-type stars. Fundamental questions about their formation history,physical properties, internal structure, and atmosphere composition are,however, still to be solved. We present here the detection of a systemof four low-mass planets around the bright (V = 5.5) and close-by (6.5pc) star HD 219134. This is the first result of the Rocky Planet Searchprogramme with HARPS-N on the Telescopio Nazionale Galileo in La Palma.The inner planet orbits the star in 3.0935 ± 0.0003 days, on aquasi-circular orbit with a semi-major axis of 0.0382 ± 0.0003AU. Spitzer observations allowed us to detect the transit of the planetin front of the star making HD 219134 b the nearest known transitingplanet to date. From the amplitude of the radial velocity variation(2.25 ± 0.22 ms-1) and observed depth of the transit(359 ± 38 ppm), the planet mass and radius are estimated to be4.36 ± 0.44 M⊕ and 1.606 ± 0.086R⊕, leading to a mean density of 5.76 ± 1.09 gcm-3, suggesting a rocky composition. One additional planetwith minimum-mass of 2.78 ± 0.65 M⊕ moves on aclose-in, quasi-circular orbit with a period of 6.767 ± 0.004days. The third planet in the system has a period of 46.66 ± 0.08days and a minimum-mass of 8.94 ± 1.13 M⊕, at0.233 ± 0.002 AU from the star. Its eccentricity is 0.46 ±0.11. The period of this planet is close to the rotational period of thestar estimated from variations of activity indicators (42.3 ± 0.1days). The planetary origin of the signal is, however, thepreferredsolution as no indication of variation at the corresponding frequency isobserved for activity-sensitive parameters. Finally, a fourth additionallonger-period planet of mass of 71 M⊕ orbits the starin 1842 days, on an eccentric orbit (e = 0.34 ± 0.17) at adistance of 2.56 AU.The photometric time series and radial velocities used in this work areavailable in electronic form at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr(ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/584/A72

Background. Laparoscopy is ever more common in both elective and emergency surgery. In fact, in abdominal emergencies it enables the resolution of preoperative diagnostic doubts as well as treatment of the underlying disease. We present a retrospective study of the results of a 5-year experience at a single center. Patients and methods. Between September 2006 and August 2011, 961 patients were treated via laparoscopy, including 486 emergency cases (15 gastroduodenal perforation; 165 acute cholecystitis; 255 acute appendicitis; 15 pelvic inflammatory disease and non-specific abdominal pain [NSAP]; 36 small bowel obstruction). All procedures were conducted by a team trained in laparoscopic surgery. Results. The conversion rate was 22/486 patients (4.53%). A definitive laparoscopic diagnosis was possible in over 96% of cases, and definitive treatment via laparoscopy was possible in most of these. Conclusions Our own experience confirms the literature evidence that laparoscopy is a valid option in the surgical treatment of abdominal emergencies. In any case, it must be performed by a dedicated and highly experienced team. Correct patient selection is also important, to enable the most suitable approach for each given situation.

Introduction. Total mesorectal excision (TME) is the cornerstone of a correct surgical therapy for extraperitoneal rectal cancer. Aim of the study is to evaluate our 5 years experience confronting retrospectively laparoscopic (lap) TME in respect to its laparotomic (open) counterpart. Patients and Methods. 30 patients were treated laparoscopically for stage I-III extraperitoneal rectal cancer and retrospectively compared to a homogeneous group, stratified for sex, age, comorbidities and stage of disease. Results. 30 days mortality was zero for both groups, while morbidity was 20% for the lap group and 36.6% for the open group. Mean lymph nodes harvested was 24 ± 12 for the lap group, 26 ± 14 for the open group (p > 0.05). Five years overall and disease free survival was respectively 82.2% and 81.4% in the lap group, 79.9% and 79.6% in the open group, without statistical significance (p>0.05). Discussion. Minimally invasive TME resulted a safe, effective and oncologically adequate procedure when retrospectively compared to its laparotomic counterpart, with 5 years overall survival and disease free survival reaching no statistical significance compared to the open approach, but with all the advantages of the laparoscopy such as less pain and blood loss, faster recovery, less morbidity and better cosmetics. Conclusions. Our study has retrospectively demonstrated that laparoscopic TME is feasible and oncologically effective, even if it remains a complex minimally invasive procedure, requiring adequate skill. More prospective, randomized studies are necessary to define such a procedure as the new gold standard in treatment of stage I-III extraperitoneal rectal cancer.

El presente trabajo representa un análisis situacional a la política pública departamental de juventud de Antioquia “PEDJ 2006-2015” en desarrollo de la “línea de acción 5. vinculación de los jóvenes al mundo laboral” en la ciudad de Medellín para el período 2006-2014. Como seguimiento a una estrategia que propicia una adecuada inserción de los jóvenes en el ámbito socioeconómico. Esta población presenta restricciones para completar un óptimo proceso de acumulación de capital humano y social que le permita insertarse en el mercado laboral en condiciones favorables. El objetivo principal consiste en analizar la inclusión de los Jóvenes al mundo laboral y otros actores sociales vinculados a la implementación y ejecución de la Política pública de juventud de Antioquia, como estrategia que garantice el tránsito de los jóvenes al mundo laboral y productivo en condiciones de calidad, estabilidad, y protección especial en los aspectos que se requieran. Las líneas de acción se enmarcan en las dimensiones de capital social, educación y mercado laboral e inserción productiva.
