Epidemiologia e caratteristiche cliniche delle candidemie in UTI: confronto con i casi internistici.

L’espressione più frequente di CI è la candidemia, più di rado si assiste ad una localizzazione primitiva profonda, che può associarsi o meno a candidemia. L'incidenza delle candidemie è in continuo aumento tra le infezioni nosocomiali; questo va di pari passo ai progressi della ricerca scientifica, alla crescente complessità delle procedure chirurgiche, alll’uso di sofisticate tecniche di supporto delle funzioni d’organo in ambito intensivistico, alll’incremento delle procedure invasive e al conseguente aumento della sopravvivenza di pazienti colpiti da patologie, che in passato avevano prognosi infausta. Lo scopo di questo studio quello di valutare l’epidemiologia e le caratteristiche cliniche della setticemia sostenuta da Candida spp. avvenute nell’Azienda Universitario-Ospedaliera Pisana e di individuare quali differenze intercorrono tra i pazienti ricoverati nei reparti di terapia intensiva/chirurgia rispetto ai pazienti internistici. I dati delle terapia intensive pisane saranno anche confrontati con i dati del GIVITI, che è un gruppo di terapie intensive italiane che raccoglie in modo prospettico le infezioni che avvengono in circa un terzo delle ICU italiane

Social networks, happiness and health: from sentiment analysis to a multidimensional indicator of subjective well-being

This paper applies a novel technique of opinion analysis over social media data with the aim of proposing a new indicator of perceived and subjective well-being. This new index, namely SWBI, examines several dimension of individual and social life. The indicator has been compared to some other existing indexes of well-being and health conditions in Italy: the BES (Benessere Equo Sostenibile), the incidence rate of influenza and the abundance of PM10 in urban environments. SWBI is a daily measure available at province level. BES data, currently available only for 2013 and 2014, are annual and available at regional level. Flu data are weekly and distributed as regional data and PM10 are collected daily for different cities. Due to the fact that the time scale and space granularity of the different indexes varies, we apply a novel statistical technique to discover nowcasting features and the classical latent analysis to study the relationships among them. A preliminary analysis suggest that the environmental and health conditions anticipate several dimensions of the perception of well-being as measured by SWBI. Moreover, the set of indicators included in the BES represent a latent dimension of well-being which shares similarities with the latent dimension represented by SWBI.Comment: 26 pages, 5 figur

Generic pure quantum states as steady states of quasi-local dissipative dynamics

We investigate whether a generic multipartite pure state can be the unique asymptotic steady state of locality-constrained purely dissipative Markovian dynamics. In the simplest tripartite setting, we show that the problem is equivalent to characterizing the solution space of a set of linear equations and establish that the set of pure states obeying the above property has either measure zero or measure one, solely depending on the subsystems' dimension. A complete analytical characterization is given when the central subsystem is a qubit. In the N-partite case, we provide conditions on the subsystems' size and the nature of the locality constraint, under which random pure states cannot be quasi-locally stabilized generically. Beside allowing for the possibility to approximately stabilize entangled pure states that cannot be exact steady states in settings where stabilizability is generic, our results offer insights into the extent to which random pure states may arise as unique ground states of frustration free parent Hamiltonians. We further argue that, to high probability, pure quantum states sampled from a t-design enjoy the same stabilizability properties of Haar-random ones as long as suitable dimension constraints are obeyed and t is sufficiently large. Lastly, we demonstrate a connection between the tasks of quasi-local state stabilization and unique state reconstruction from local tomographic information, and provide a constructive procedure for determining a generic N-partite pure state based only on knowledge of the support of any two of the reduced density matrices of about half the parties, improving over existing results.Comment: 36 pages (including appendix), 2 figure

Measuring Service Quality: The Opinion of Europeans about Utilities

This paper provides a comparative analysis of statistical methods to evaluate the consumer perception about the quality of Services of General Interest. The evaluation of the service quality perceived by users is usually based on Customer Satisfaction Survey data and an ex-post evaluation is then performed. Another approach, consisting in evaluating Consumers preferences, supplies an ex-ante information on Service Quality. Here, the ex-post approach is considered, two non-standard techniques - the Rasch Model and the Nonlinear Principal Component Analysis - are presented and the potential of both methods is discussed. These methods are applied on the Eurobarometer Survey data to assess the consumer satisfaction among European countries and in different years.Service Quality, Eurobarometer, Non Linear Principal Component Analysis, Rasch Analysis, Conjoint Analysis

How Do the Others See Us? An Analysis of Public Opinion Perceptions of the EU and USA in Third Countries

The European Union and the United States are global actors involved in intense relations with third countries and the outside world, which pertain economic, political, diplomatic, and security-related aspects. The US has been facing in recent years a growing number of challenges from non-Western rising powers. The EU has for a while played a more assertive role vis-à-vis the outside world following a process of internal consolidation of its own institutions and structures and these developments seem to reflect a wider process of regionalisation of global relations. This study provides a comprehensive review of the existing surveys addressing the external perceptions of the EU and the US, thereby contributing to drawing their external image in its different shades: their role in the global economy, international security, human rights and democracy promotion.

Indigenous Knowledge’s for Healthy Habits and Life

Health and habits are interrelated. Our older generations viewed nature and all living beings as the beads of the same manacle. From rising up early in the morning till the moment of sleep enraptures us at night we are entangled in various activities that goes hand in hand with nature. Our ancestors realized much earlier that the pros and cones of these deeds will reflect through our health
