Propagation and field of âBN4 Krâ â a promising sharka resistant rootstock.
Different âMirobolanâ types are still largely used for Prunus sp. propagation. The rootstock resistance has great practical importance in order to limit the spread of Plum pox virus (PPV), given that root suckers represent gateways for the virus. Minoiu and VlÄdianu (2001) had developed a mutant of âMirobolanâ, named âBN 4 Krâ at the BistriĆŁa Fruit Research and Development Station, which has been proven resistant to PPV (Minoiu et al., 1997, 1998). Other experiments have confirmed that aphid vectors are not able to transmit PPV to âMirobolanâ âBN 4 Krâ plants (PolĂĄk and Kominek, 2014). In order to check the potential of large-scale propagation of âBN 4 Krâ, green cuttings and in vitro propagation were studied. Green cuttings propagation was assessed for three consecutive years using different rooting substrates: sand, perlite, and a 1:1 mix of sand and perlite. The results revealed an average rooting between 75.3 and 85.9%, with the highest rooting percentage on the perlite variant. In vitro propagation of âBN 4 Krâ rootstock was tested at Vitroplant Italia. Best culture medium was Murashige and Skoog (1962) supplemented with 2.0 mg L-1 BA and with 0.01 mg L-1 IBA for stabilization, 1.0 mg L-1 BA and 0.01 mg L-1 IBA for multiplication, and 1.5 mg L-1 IBA for rooting. In central Italy (Valdaso, Ancona Province) Polytechnic University of Marche (Ancona, Italy) tested the âBN 4 Krâ rootstocks in replanting conditions, using âMyrobalan 29Câ as a control. One-year-old trees of âBN 4 Krâ were planted in November 2007 and grafted with âFortuneâ plum in February 2009. The production and fruit quality were recorded from 2011-2015. The âFortuneâ on âBN 4 Krâ rootstock showed a production similar to âMyrobalan 29Câ but with lower vigour and slightly bigger fruit size. Likely âBN 4 Krâ rootstock induced a lower incidence of phytoplasma symptoms (ESFY), which are a growing problem in plum production. The resistance to PPV correlated with the high potential of vegetative propagation, recommending âBN 4 Krâ as a promising âMirobolanâ rootstock for sharka containment. The exclusive license for propagation and commercialization of âBN 4 Krâ was awarded to Vitroplant Italia, starting with 2016
Potentially preventable hospitalisation in an Italian district (2006-2011)
Introduction
The potentially preventable hospitalisations (PPH) include hospitalisation that could be avoided through policies for primary prevention. Representing an earlier indicator than mortality, it allows to evaluate the outcome of health interventions in shorter times also taking into account the increasingly longer survival in presence of disease.
The purpose of this study was to consider the use of data on PPH as an index of health inequalities in the population, susceptible to primary prevention, and estimate the costs relating to it.
Methods
We analyzed the flow of five years (2006-2011) of hospital discharge records regarding an Italian local health unit (province of Grosseto, 228384 inhabitants, Tuscany Region). We considered the potentially preventable causes of avoidable hospitalisation, suggested by the Epidemiology and Applied ResearchProgram (ERA), occurred in people under 75 years old, native and foreigners. We added the voluntary interruption of pregnancy (VIP) to the ERAâs causes of PPH.
Results
The PPH are about 9% of all hospitalisations.
The relative risk for a male than a female is 1.5 (excluding VIP).
Foreigners have a half relative risk of PPH compared to italians (7.4 vs13.3); including among the causes the VIP the risk becomes equal (14.6vs 14.8).
The cost ofPPH represents 10.3% of total hospital expenditure, rising to 12.8% with VIP.
The distribution of the specific causes of PPH is different between natives and foreigners:in the latter we noticed reduced percentages of cardiomyopathies (13% vs 29%) and cancer (4% vs 12%), whereas an increased percentage of trauma (74% vs 48%):relative risks respectively of 0.42, 0.31 and 1.57.
VIP across the whole population are placed in third place as causes of PPH, while if we consider only the immigrants they are placed in first place (49% of PPH).
Conclusions
The comparable rate of PPH between immigrants and italians could mean that there is fairness in the accessibility to primary prevention policies. The data on different relative risks for specific causes albeit partly due to the different composition of the two populations should be considered in the bid of services. The VIP should be routinely considered among the PPH, in view of its avoidance with interventions in health education / contraception

Sorveglianza e prevenzione nutrizionale nella popolazione giovanile della Provincia di Livorno
Organizzazione della filiera vivaistica e certificazione delle piante.
Le tecniche di moltiplicazione, l'uso del portinnesto, la micropropagazione: molti gruppi di ricerca in Italia sono attivi nel miglioramento dei sistemi di propagazione del nocciolo. Avanzano anche i lavori per lo sviluppo del programma di certificazione genetico sanitaria, su base volontaria, del materiale vivaistico che, alla luce del mutato quadro normativo europeo, dovrebbe essere operativo entro la fine del 2017
