Avalia??o e evidência clínica na saúde mental
Viganò, Carlo;
Revista Latinoamericana de Psicopatologia Fundamental , 2010, DOI: 10.1590/S1415-47142010000300007
Abstract: this paper is on the topic of "evaluation and clinical evidence" and its relevance to the italian context of mental health services. the subject is discussed based on the method of "clinical case construction," which is being developed at the school of specialization in psychiatry of the university of milan. the practice of presenting and discussing cases is a way of evaluating the quality of these services. it is also proof that an evaluation tool can be developed which includes the singularity of the symptom as the axis of clinical work.
Extreme cities and bad places
Paola Viganò
International Journal of Disaster Risk Science , 2012, DOI: 10.1007/s13753-012-0002-6
Abstract: This article considers places where climate change-induced hazards will be particularly important, focusing on two examples, the lagoon location of Venice and the Garonne riverbank location of Bordeaux. The Venice lagoon territory is close to the coast and has a dispersed form of urban development. Our project experiments resulted in the formulation of a series of adaptation strategies to increased disaster risks, including returning current agricultural land and residential areas to their original state as wetlands and marshes before their reclamation during the early decades of the twentieth century. The scenarios introduce space as a relevant variable into the debate about the impact of climate change and adaptation. This article also deals with the recovery of “bad places,” such as the urban blight on the Garonne riverbanks of Bordeaux, and their relationship with sustainability and disaster risks. Increasingly, the emphasis on minimizing energy consumption and promoting recycling forces cities to reuse places of elevated risk. Only very recently in modern urban planning are polluted and risky areas frequently selected for new development projects to reclaim the vast areas of existing brownfields in the name of sustainability. Integrating disaster risk reduction into a new economic and social context has thus become an extremely important part of contemporary urban design and planning for these reclaimed (bad) areas. The research concludes that urban and territorial design should and can integrate the inevitability of risk. This is necessary for developing approaches and strategies that offer some rethinking about “wicked” problems, long-term time horizons, radical imagination, dynamic representations, and minute territorial readings in contemporary urban planning.
La lucha contra el terrorismo de matriz islámica a través del Derecho penal: la experiencia italiana.
Francesco Viganò
Política criminal , 2007,
Abstract: El artículo da cuenta de la línea seguida por el sistema penal italiano en materia de oposición al terrorismo de matriz islámica. Tras exponer la dicotomía entre la “vía norteamericana” y la “víaeuropea” de enfrentamiento del mencionado fenómeno, el autor toma posición en el debate sobre el denominado derecho penal del enemigo, concluyendo que la oposición al terrorismo debe continuar pasando a través del derecho y la jurisdicción penal, y que es tarea de la ciencia penal orientar a la los poderes creadores del derecho criminal en la búsqueda de un punto de equilibrio sostenible entredefensa social y garantías. En seguida se examinan los tipos penales italianos más relevantes utilizados en la práctica de la oposición al terrorismo islámico. Se dedica una atención especial a la participación en una asociación terrorista, figura que, junto con constituir el eje en la materia, ofrece la mayor problematicidad desde el punto de vista de la compatibilidad con los principios constitucionales.
Treatment strategy for colorectal cancer with resectable synchronous liver metastases: Is any evidence-based strategy possible?
Luca Viganò
World Journal of Hepatology , 2012, DOI: 10.4254/wjh.v4.i8.237
Abstract: Fifteen percent to twenty-five percent of patients affected by colorectal cancer presents with liver metastases at diagnosis. In resectable cases, surgery is the only potentially curative treatment and achieves survival rates up to 50% at 5 years. Management is complex, as colorectal resection, liver resection, chemotherapy, and, in locally advanced mid/low rectal tumors, radiotherapy have to be integrated. Modern medical practice usually relies on evidence-based protocols. Levels of evidence for synchronous metastases are poor: published studies include few recent prospective series and several retrospective analyses collecting a limited number of patients across long periods of time. Data are difficult to be generalized and are mainly representative of single centre’s experience, biased by local recruitment, indications and surgical technique. In this context, surgeons have to renounce to “evidence-based medicine” and to adopt a sort of “experience-based medicine”. Anyway, some suggestions are possible. Simultaneous colorectal and liver resection can be safely performed whenever minor hepatectomies are planned, while a case-by-case evaluation is mandatory in case of more complex procedures. Neoadjuvant chemotherapy is preferentially scheduled for patients with advanced metastatic tumors to assess disease biology and to control lesions. It can be safely performed with primary tumor in situ, even planning simultaneous resection at its end. Locally advanced mid/low rectal tumor represents a further indication to neoadjuvant therapies, even if treatment’s schedule is not yet standardized. In summary, several issues have to be solved, but every single HPB centre should define its proper strategy to optimize patient’s selection, disease control and safety and completeness of surgery.

Magnetic fields in neutron stars
Daniele Viganò
Physics , 2013,
Abstract: This work aims at studying how magnetic fields affect the observational properties and the long-term evolution of isolated neutron stars, which are the strongest magnets in the universe. The extreme physical conditions met inside these astronomical sources complicate their theoretical study, but, thanks to the increasing wealth of radio and X-ray data, great advances have been made over the last years. A neutron star is surrounded by magnetized plasma, the so-called magnetosphere. Modeling its global configuration is important to understand the observational properties of the most magnetized neutron stars, magnetars. On the other hand, magnetic fields in the interior are thought to evolve on long time-scales, from thousands to millions of years. The magnetic evolution is coupled to the thermal one, which has been the subject of study in the last decades. An important part of this thesis presents the state-of-the-art of the magneto-thermal evolution models of neutron stars during the first million of years, studied by means of detailed simulations. The numerical code here described is the first one to consistently consider the coupling of magnetic field and temperature, with the inclusion of both the Ohmic dissipation and the Hall drift in the crust.
Packing and Covering a Polygon with Geodesic Disks
Ivo Vigan
Computer Science , 2013,
Abstract: Given a polygon $P$, for two points $s$ and $t$ contained in the polygon, their \emph{geodesic distance} is the length of the shortest $st$-path within $P$. A \emph{geodesic disk} of radius $r$ centered at a point $v \in P$ is the set of points in $P$ whose geodesic distance to $v$ is at most $r$. We present a polynomial time $2$-approximation algorithm for finding a densest geodesic unit disk packing in $P$. Allowing arbitrary radii but constraining the number of disks to be $k$, we present a $4$-approximation algorithm for finding a packing in $P$ with $k$ geodesic disks whose minimum radius is maximized. We then turn our focus on \emph{coverings} of $P$ and present a $2$-approximation algorithm for covering $P$ with $k$ geodesic disks whose maximal radius is minimized. Furthermore, we show that all these problems are $\mathsf{NP}$-hard in polygons with holes. Lastly, we present a polynomial time exact algorithm which covers a polygon with two geodesic disks of minimum maximal radius.
High-contrast imaging of Sirius~A with VLT/SPHERE: Looking for giant planets down to one astronomical unit
A. Vigan,C. Gry,G. Salter,D. Mesa,D. Homeier,C. Moutou,F. Allard
Physics , 2015, DOI: 10.1093/mnras/stv1928
Abstract: Sirius has always attracted a lot of scientific interest, especially after the discovery of a companion white dwarf at the end of the 19th century. Very early on, the existence of a potential third body was put forward to explain some of the observed properties of the system. We present new coronagraphic observations obtained with VLT/SPHERE that explore, for the very first time, the innermost regions of the system down to 0.2" (0.5 AU) from Sirius A. Our observations cover the near-infrared from 0.95 to 2.3 $\mu$m and they offer the best on-sky contrast ever reached at these angular separations. After detailing the steps of our SPHERE/IRDIFS data analysis, we present a robust method to derive detection limits for multi-spectral data from high-contrast imagers and spectrographs. In terms of raw performance, we report contrasts of 14.3 mag at 0.2", ~16.3 mag in the 0.4-1.0" range and down to 19 mag at 3.7". In physical units, our observations are sensitive to giant planets down to 11 $M_{Jup}$ at 0.5 AU, 6-7 $M_{Jup}$ in the 1-2 AU range and ~4 $M_{Jup}$ at 10 AU. Despite the exceptional sensitivity of our observations, we do not report the detection of additional companions around Sirius A. Using a Monte Carlo orbital analysis, we show that we can reject, with about 50% probability, the existence of an 8 $M_{Jup}$ planet orbiting at 1 AU. In addition to the results presented in the paper, we provide our SPHERE/IFS data reduction pipeline at http://people.lam.fr/vigan.arthur/ under the MIT license.

Abstract: Objective: To compare the nutritional content of the main meals of a normal hospital diet with those of texture modified diets (soft, puréed and liquid). Methodoloogy: The ash, moisture, macronutrient and energy contents of the foods comprising the main meal of the hospital diets were determined. The values were calculated per capita for each food item comprising the diets and then added up in order to estimate the total amount of energy and macronutrients supplied by main meal. Results: Compared with the normal diet, the puréed and liquid diets presented higher moisture content as well as reduced content of energy (31.4% and 39.9%, respectively), protein (45.4% and 79.8% ,respectively) and lipid (41% and 76%, respectively). Conclusion: Texture modified diets exhibit lower energy and macronutrient content, the main changes being detected for the liquid diet, which might imply an insufficient micronutrient supply. Objetivo: Comparar la composición nutricional de las comidas principales en la dieta hospitalaria en general con los de las dietas modificadas para la consistencia (blanda, puré y líquida). Metodología: Se determinó el contenido de cenizas, humedad, nutrientes y energía de los alimentos de la comida principal de las dietas hospitalarias recogidas. Los valores fueron convertidos a cantidades per cápita establecidas para cada alimento de cada dieta y sumados con el fin de estimar el total ofrecido por la comida principal. Resultados: Las dietas líquida y puré tuvieron más humedad, reducción de 41 a 76.0% del contenido de grasas, reducción de 45.4 a 79.8% del contenido proteico y de 31.9 a 39.9% de la energía total. Conclusión: Las dietas de consistencia modificada presentaron una reducción en el contenido de energía y macronutrientes, encontrándose los principales cambios en la dieta líquida, lo que culminó en una probable disminución de la ingesta de micronutrientes.
