Effetti degli accordi Euro-Mediterrani sul comparto dell'ortofrutta fresca

In 1995, the European Union (EU) Member States and 12 Mediterranean countries launched in Barcelona a liberalization process that aims at establishing a free trade area (to be realized by 2010) and at promoting a sustainable and balanced economic development by the adoption of a new generation of Agreements: the Euro-Mediterranean Agreements (EMA). For the Mediterranean partner countries, the main concern is a better access for their fruit and vegetable exports to the European market. These products represent the main exports of these countries, and the EU is their first trading partner. On the other side, for the EU the main issue is not only the promotion of its products, but also the protection of its fruit and vegetables producers. Moreover, the trade with third countries is the key element of the Common Market Organization of the sector. Fruit and vegetables represent a very sensitive sector since their high seasonality, high perishability, and especially since the production of the Mediterranean countries is often similar to the European Mediterranean’s countries one. In fact, the agreements define preferences at the entrance of the EU market providing limited concessions for each partner, for specific products, limited quantities and calendars. This research tries to analyze the bilateral trade volume for fresh fruit and vegetables in the European and Italian markets in order to assess the effects of Mediterranean liberalization on this sector. Free trade of agricultural products represents a very actual topic in international trade and the Mediterranean countries, recognised as big producers of fruit and vegetables, as big exporters of their crops and actually significantly present on the European market, could be high competitors with the inward production because the outlet could be the same. The goal of this study is to provide some considerations about the competitiveness of mediterranean fruit and vegetables productions after Barcelona Process, in a first step for the European market and then also for the Italian one. The aim is to discuss the influence of the euro-mediterranean agreements on the fruit and vegetables trade between 10 foreign Mediterranean countries (Algeria, Egypt, Israel, Jordan, Libya, Lebanon, Morocco, Tunisia, Syria, and Turkey) and 15 EU countries in the period 1995-2007, by means of a gravity model, which is a widespread methodology in international trade analysis. The basic idea of gravity models is that bilateral trade from one country to another (as the dependent variable) can be explained by a set of factors: - factors that capture the potential of a country to export goods and services; - factors that capture the propensity of a country to imports goods and services; - any other forces that either attract or inhibit bilateral trade. This analysis compares only imports’ flows by Europe and by Italy (in volumes) from Mediterranean countries, since the exports’ flows toward those foreign countries are not significant, especially for Italy. The market of fruit and vegetables appears as a high heterogeneous group so it is very difficult to show a synthesis of the analysis performed and the related results. In fact, this sector includes the so called “poor products” (such as potatoes and legumes), and the “rich product”, such as nuts or exotic fruit, and there are a lot of different goods that arouse a dissimilar consumer demand which directly influence the import requirements. Fruit and vegetables sector includes products with extremely different biological cycles, leading to a very unlike seasonality. Moreover, the Mediterranean area appears as a highly heterogeneous bloc, including countries which differ from the others for economic size, production potential, capability to export and for the relationships with the EU. The econometric estimation includes 68 analyses, 34 of which considering the European import and 34 the Italian import and the products are examined in their aggregated form and in their disaggregated level. The analysis obtains a very high R2 coefficient, which means that the methodology is able to assess the import effects on fruit and vegetables associated to the Association Agreements, preferential tariffs, regional integration, and others information involved in the equation. The empirical analysis suggests that fruits and vegetables trade flows are well explained by some parameters: size of the involved countries (especially GDP and population of the Mediterranean countries); distances; prices of imported products; local production for the aggregated products; preferential expressed tariffs like duty free; sub-regional agreements that enforce the export capability. The euro-mediterranean agreements are significant in some of the performed analysis, confirming the slow and gradual evolution of euro- Mediterranean liberalization. The euro-mediterranean liberalization provides opportunities from one side, and imposes a new important challenge from the other side. For the EU the chance is that fruit and vegetables imported from the mediterranean area represent a support for local supply and a possibility to increase the range of products existing on the market. The challenge regards the competition of foreign products with the local ones since the types of productions are similar and markets coincide, especially in the Italian issue. We need to apply a strategy based not on a trade antagonism, but on the realization of a common plane market with the Mediterranean countries. This goal could be achieved enhancing the industrial cooperation in addition to commercial relationships, and increasing investments’ flows in the Mediterranean countries aiming at transforming those countries from potential competitors to trade partners and creating new commercial policies to export towards extra European countries.

Dati preliminari dello studio multicentrico caso-controllo "Grave danno epatico acuto indotto da farmaci"

Il danno epatico indotto dall'assunzione di farmaci viene comunemente indicato con il termine inglese DILI (Drug-Induced Liver Injury). Il paracetamolo rappresenta la causa più comune di DILI, seguito da antibiotici, FANS e farmaci antitubercolari. In particolare, i FANS sono una delle classi di farmaci maggiormente impiegate in terapia. Numerosi case report descrivono pazienti che hanno sviluppato danno epatico fatale durante il trattamento con FANS; molti di questi farmaci sono stati ritirati dal commercio in seguito a gravi reazioni avverse a carico del fegato. L'ultimo segnale di epatotossicità indotto da FANS è associato alla nimesulide; in alcuni paesi europei come la Finlandia, la Spagna e l'Irlanda, la nimesulide è stata sospesa dalla commercializzazione perché associata ad un'alta frequenza di epatotossicità. Sulla base dei dati disponibili fino a questo momento, l'Agenzia Europea dei Medicinali (EMA) ha recentemente concluso che i benefici del farmaco superano i rischi; un possibile aumento del rischio di epatotossicità associato a nimesulide rimane tuttavia una discussione aperta di cui ancora molto si dibatte. Tra le altre classi di farmaci che possono causare danno epatico acuto la cui incidenza tuttavia non è sempre ben definita sono gli antibiotici, quali amoxicillina e macrolidi, le statine e gli antidepressivi.Obiettivo dello studio è stato quello di determinare il rischio relativo di danno epatico indotto da farmaci con una prevalenza d'uso nella popolazione italiana maggiore o uguale al 6%. E’ stato disegnato uno studio caso controllo sviluppato intervistando pazienti ricoverati in reparti di diversi ospedali d’Italia. Il nostro studio ha messo in evidenza che il danno epatico da farmaci riguarda numerose classi farmacologiche e che la segnalazione di tali reazioni risulta essere statisticamente significativa per numerosi principi attivi. I dati preliminari hanno mostrato un valore di odds ratio significativo statisticamente per la nimesulide, i FANS, alcuni antibiotici come i macrolidi e il paracetamolo.
