Efficacy and safety of rituximab with and without methotrexate in the treatment of rheumatoid arthritis patients: Results from the GISEA register
2014
Abstract Introduction Rituximab (RTX) is a monoclonal anti-CD20 antibody approved for the treatment of rheumatoid arthritis (RA) in association with methotrexate (MTX). Objectives To evaluate the efficacy and safety of RTX–MTX combination therapy compared with RTX alone in the treatment of RA. Methods We analyzed data from a prospective cohort study, the Italian biologic register GISEA, to investigate the efficacy and safety of rituximab. Moreover, the adverse events (AE) and the causes of discontinuation therapy were analyzed. Results We identified 338 RA patients, 162 treated with RTX and 176 with RTX–MTX. After 52 and 104 weeks of therapy the disease activity score in 28 joints and the H…

A global network for the control of snail-borne disease using satellite surveillance and geographic information systems
2001
Abstract At a team residency sponsored by the Rockefeller Foundation in Bellagio, Italy, 10-14 April 2000 an organizational plan was conceived to create a global network of collaborating health workers and earth scientists dedicated to the development of computer-based models that can be used for improved control programs for schistosomiasis and other snail-borne diseases of medical and veterinary importance. The models will be assembled using GIS methods, global climate model data, sensor data from earth observing satellites, disease prevalence data, the distribution and abundance of snail hosts, and digital maps of key environmental factors that affect development and propagation of snail…
Localizzazione ottimale degli stalli per il parcheggio delle biciclette: il caso studio della città di Palermo - Optimal location for bike parking lo…
2015
The lack of parking spaces for bicycles is one of the main issues that many cities face. A proper planning of a bike station network is necessary in order to optimize the whole urban system and the transport supply. In this work a step-by-step analysis is proposed to find the best location for the bicycle lots in the old town of Palermo. The optimization method includes the use of both a Set Covering Model and a Maximum Coverage Location Problem. The dataset for the simulations was collected by direct and indirect surveys on the population and implemented into Open source GIS software. In particular, data on the destinations, times and distances covered by the bicycles’ users were included.…
Il GIS per il monitoraggio e la gestione del ciclo integrato dei rifiuti in Sicilia
2013
Il problema dei rifiuti è una questione di grande attualità e di rilevanza nazionale: ogni giorno i servizi d’informazione trattano della cosiddetta “emergenza rifiuti” anche se, visto il perdurare e il rinnovarsi di tante “emergenze”, si dovrebbe parlare di ordinaria situazione di inefficienza del sistema di smaltimento. In realtà, la situazione della “gestione dei rifiuti” risulta essere assai più complessa di quanto emerga dai media nazionali. È ancora più arduo scoprire le “falle” del sistema e ricercare le motivazioni di una tale inefficienza, poiché, nella stessa penisola, l’applicazione della normativa di settore è avvenuta in maniera differente e disomogenea. Per questo arduo compit…

Understanding the Key Factors of Shared Mobility Services: Palermo as a Case Study
2020
The potential success of shared mobility services in the urban area strongly depends on careful tariff planning, adequate sizing of the fleet and efficient integrated public transport system, as well as on the application of policies in favor of sustainable modes of transport. The balance between earnings and expenses is not always an easy target for the companies in those cities where these services are not well-rooted in the citizens’ mobility habits. Often only large operators in the sector can continue to offer a service generating profit. However, several factors can determine the success or the failure of shared mobility services. The objective of this study is to identify, thanks to …

The use of species in plantations: renaturalisation and reforestation in Sicily
2017
Afforestation and reforestation activities in Sicily have been widespread in the last century, in order to increase the forest cover that was seriously reduced in the former centuries. Notwithstanding this, Sicily is still characterized by only the 12% of the regional surface covered by woods and forest. The reforestation in the last century was carried out using conifers and eucalypts, just in order to ensure a quick protection of slopes and pastureland, coping diffuse erosion events, and those intervention had a remarkable success. Nowadays, the target of enlarging the forest areas in the island is still compulsive, but the use of species, considering the actual knowledge and nature consc…
