Patient Preference and Adherence , 2011,
Abstract: Giuseppe Emanuele La Piana1, Alessandro Scartabellati1, Lodovico Chiesa1, Luca Ronchi1, Paola Raimondi1, Miriam A Carro1, Silvia Zibetti1, Stefano Aiolfi2 1Pulmonary Rehabilitation Unit, S. Marta Hospital, Rivolta D'Adda; 2Unit of Pneumology, AO Ospedale Maggiore di Crema, Crema, Italy Background: Lack of adherence with continuous positive airway pressure (CPAP) therapy is the major cause of treatment failure in patients with obstructive sleep apnea syndrome. We evaluated the effectiveness of our intensive educational program on adherence in the short term and the long term. Methods: The educational program consisted of: intensive training, whereby each patient performed individual and collective sessions of three hours receiving information about obstructive sleep apnea syndrome, familiarizing themselves with CPAP tools, on six consecutive days; long-term training; and support meetings, with reassessment at three months and one year. Results: In 202 patients with obstructive sleep apnea syndrome, the mean (standard deviation) apnea/hypopnea index was 45 ± 22, the Epworth Sleepiness Scale score was 14 ± 5, and the average titration pressure was 10 ± 2 cm H2O. At three months, 166 patients (82%) used CPAP for an average of 7.3 hours per night. At one year, 162 (80%) used CPAP for about seven hours per night. At two years, 92 patients (43%) used CPAP for about five hours per night. The level of satisfaction remained higher in patients in ventilation. Conclusion: Our data show strong adherence to CPAP at three months and one year, with a decrease at two years. The initial educational program seems to play an important role in adherence. This effect is lost in the long term, suggesting that periodic reinforcement of educational support would be helpful.

International Journal of COPD , 2011,
Abstract: Giuseppe Emanuele La Piana1, Luciano Corda2, Enrica Bertella1, Luigi Taranto Montemurro1, Laura Pini1, Claudio Tantucci11Cattedra di Malattie dell'Apparato Respiratorio, Università di Brescia, 2Prima Divisione di Medicina Interna, Spedali Civili, Brescia, ItalyBackground: Use of short-acting 2-agonists in chronic obstructive pulmonary disease (COPD) during treatment with long-acting 2-agonists is recommended as needed, but its effectiveness is unclear. The purpose of this study was to assess the additional bronchodilating effect of increasing doses of salbutamol during acute and chronic treatment with formoterol in patients with COPD.Methods: Ten patients with COPD underwent a dose-response curve to salbutamol (until 800 μg of cumulative dose) after a 1-week washout (baseline), 8 hours after the first administration of formoterol 12 μg (day 1), and after a 12-week and 24-week period of treatment with formoterol (12 μg twice daily by dry powder inhaler). Peak expiratory flow, forced expiratory volume in one second (FEV1), forced vital capacity, and inspiratory capacity were measured at the different periods of treatment and at different steps of the dose-response curve.Results: Despite acute or chronic administration of formoterol, maximal values of peak expiratory flow, FEV1, and forced vital capacity after 800 μg of salbutamol were unchanged compared with baseline. The baseline FEV1 dose-response curve was steeper than that at day 1, week 12, or week 24 (P < 0.0001). Within each dose-response curve, FEV1 was different only at baseline and at day 1 (P < 0.001), when FEV1 was still greater at 800 μg than at 0 μg (P < 0.02). In contrast, the forced vital capacity dose-response curves were similar at the different periods, while within each dose-response curve, forced vital capacity was different in all instances (P < 0.001), always being higher at 800 μg than at 0 μg (P < 0.05).Conclusion: In patients with stable COPD, the maximal effect of salbutamol on peak expiratory flow, FEV1, and forced vital capacity was unchanged after either acute or chronic treatment with formoterol. With increasing doses of salbutamol, FEV1 increased only after acute administration of formoterol. Forced vital capacity also significantly improved during long-term treatment with formoterol.Keywords: chronic obstructive pulmonary disease, salbutamol, formoterol, long-acting 2-agonists

Calculation of Exclusive Cross Sections with the Lorentz Integral Transform Method
Alessandro La Piana,Winfried Leidemann
Physics , 2000, DOI: 10.1016/S0375-9474(00)00310-9
Abstract: The longitudinal structure function of the d(e,e'p) exclusive cross section is calculated with the Lorentz integral transform method. In this approach final state interaction is fully taken into account, but without using a final state wave function. Cross sections are obtained via the inversion of the transform. It is shown that the inversion results are very stable. The comparison to a conventional calculation with an explicit np final state wave function shows that the obtained results are also very precise. Thus the method opens up the possibility to obtain exclusive cross sections for reactions with more than two particles, where it is generally very difficult to calculate the exact final state wave function.

The imagetic construction of a crime: analysis of magazine covers on the case of Isabella Nardoni A constru o imagética de um crime: análise das capas de revistas sobre o caso Isabella Nardoni
Andréa Gama Piana
Discursos Fotográficos , 2012, DOI: 10.5433/11937
Abstract: Since the beginning of time, the image has been present in our lives, taking up different functions. Throughout history, production and support techniques have changed and the image has gained more power to a point where, in some moments, it substitutes texts and drives opinion making. Therefore, the objective of this work is to analyze the visual elements found on the covers of Veja, Isto é and época on the Isabela Nardoni’s case, verifying the significance of the image for the construction of narratives surrounding the facts. The theoretical and conceptual background used in the analysis is based on two authors: Harry Pross, who, through his signs relational theory, searches for the visual readings of several cultural texts by an axes interpretation (insideoutside, above-below, bright-dark). The other author, Ivan Bystrina, one of the main thinkers in Culture Semiotics, like Pross, understands the perception by axes, or poles, stressing that the negative always attracts more attention, emphasizing that these characteristics are based on archaic values still ingrained in man. In this work, it was possible to see, through the exposed references, significant elements for the visual construction of the narrative of a crime on magazine covers. Desde nossos primórdios, a imagem esteve presente assumindo diferentes fun es no tempo. Ao longo da história, as técnicas de produ o e suportes se modificam e a imagem ganha um espa o cada vez maior a ponto de, em determinados momentos, substituir os próprios textos e direcionar a forma o de opini es. Assim objetivou-se analisar os elementos visuais presentes nas capas das revistas Veja, Isto é e época, referentes ao caso Isabella Nardoni, anotando a significa o da imagem para uma constru o de narrativas em torno dos fatos. O embasamento teórico e conceitual utilizado na realiza o das análises segue o pensamento de dois autores, sendo o primeiro Harry Pross que, através de sua teoria relacional dos signos busca por meio da interpreta o dos eixos (dentro-fora, acima-abaixo, claroescuro), permite leituras visuais em diversos textos culturais. Outro autor que dá base para as análises é Ivan Bystrina, sendo este um dos principais pensadores da Semiótica da Cultura, e assim como Pross, também compreende a percep o por eixos, ou polos, enfatizando que o negativo sempre acaba por atrair mais a aten o, destacando que essas características s o baseadas em valores arcaicos ainda presentes no homem. Neste trabalho, foi possível perceber, por meio dos referencias expostos, elementos de significancia para a constru o vi
Bringing the Outside inside: Macro and Micro Factors to Put the Dialogue among Highest Courts into its Right Context
Daniela Piana,Carlo Guarnieri
Utrecht Law Review , 2012,
Abstract: High courts have been front-running actors in breaking domestic boundaries and enacting cross-border dialogue. This seems to be due to several factors: the increasingly transnational nature of the law, the development of influential arenas and networks where judges - particularly those sitting in high courts - meet and exchange ideas and the fact that similar cases are submitted to different courts. This phenomenon, despite being hotly debated, is still in need of a comprehensive explanation. Why do judges follow behavioural patterns that increasingly seem to rely on the decisions and the arguments adopted by their colleagues working in foreign courts? This paper does not offer an ultimate answer to this complex question, but tries to highlight the institutional and professional conditions one can expect to play a significant role in encouraging the dialogue among European high courts.
Hacia una democracia.com? Democracia y tecnologías

Sequência : Estudos Juridicos e Politicos , 2007,
Abstract: Internet puede convertirse en un canalpara fomentar la responsabilidad horizontal y crearuna interacción más participativa entre ciudadanos,gobernantes y organizaciones de la sociedad civil. Lacreciente crisis de representación ha hecho que lamodernización del Estado aparezca, cada vez más,como un tema central de la campa a política. Peroantes de dise ar y aplicar faraónicos procesos de reforma,es necesario estudiar si verdaderamente las TIChan contribuido en el proceso de reforma del Estado ycuáles son los usos que reciben estos instrumentospor parte de los gobernantes y los ciudadanos. Lalógica de la Sociedad de la Información no es inevitable:Internet y las TIC alterarán la gramática del poder,pero cómo lo harán, dependerá de qué uso quierandárseles. Supondrán la democratización ypopularización de los métodos de acceso y distribuciónde información si son utilizadas inteligentemente enuna sociedad con cultura digital. Si no, sólo serán unaherramienta potenciadora de los actuales modelos deexclusión y de democracias imperfectas.Internet may become a channel topromote horizontal accountability, creating a morecooperative interaction between citizens,government officials and civil society organizations.The growing crisis of representation has caused thestate modernization to each time appear increasinglyas the central focus in politician campaigns. Butbefore building and implementing enormous reformprocesses, it is necessary to research whether theInformation and Communications Technology (ICT)has actually contributed to the state reform andwhat uses these instruments receive from governorsand citizens. Information Society logic is notinevitable: Internet and the ICT will modify thegrammar of the political power, but we do not knowhow. It depends on what use we will give them.They will democratize the access and distributionof information if they are used intelligently in asociety with digital culture. If not, these tools willincrease exclusion patterns and imperfectdemocracies.
EFFECT OF PULPAL PRESSURE ON MICROTENSILE BOND STRENGTH OF SELF-ETCH SYSTEMS TO DENTIN. APPLICATION OF TWO ADHESIVE LAYERS
Montanari Marco,Piana Gabriela
Journal of International Dental and Medical Research , 2010,
Abstract: The first objective of this study was to examine effect of simulated hydrostatic pulpal pressure (PP) on μTBS of Bond Force (BF) (Tokuyama Corp., Tokyo, Japan), applied in a single or double layer. The second objective was to evaluate dentin location influence (superficial and deep) on μTBS.Flat coronal dentin surfaces of extracted human molars were prepared. Two groups were created with two different conditions of PP. In group A no PP was present (0 cm) during BF application and composite build-up. In group B a PP (20 cm H2O) was present during BF application. Specimens bonded under PP were stored in water at 37C° under 20 cm H2O for 20 min. For both groups BF was applied in single (subgroups A1,B1) or double layer (A2,B2). Flowable resin composite (Estelite Flow Quick Tokuyama Corp., Tokyo, Japan) was used for the build-up. Beams with a 1.0 mm2 area were obtained and stressed to failure using microtensile tester.Application of two layers of BF showed higher μTBS than single application in all tested conditions. PP was responsible for a statistical reduction in μTBS only when Bond Force was applied in single coat. Superficial dentin showed higher values than deep dentin in all conditions but no statistical differences were found. A highly significant correlation was observed between droplets presence and μTBS results.The application of a double layer of BF is a clinical requirement to avoid the reduction in μTBS and prevent any interference of pulpal pressure.
