    Con questa ricerca sono state individuate le Aree prioritarie per la conservazione della biodiversità della provincia di Novara quale operazione di partenza al fine di disegnare, in una fase successiva, la Rete Ecologica Provinciale su basi naturalistiche. A questa operazione hanno partecipato 26 naturalisti esperti, ossia dotati di competenze personali pregresse e di adeguata conoscenza del territorio della provincia di Novara, per i seguenti 6 temi focali: (a) Flora e vegetazione, (b) Invertebrati, (c) Anfibi e Rettili, (d) Uccelli, (e) Mammiferi, (f) Ecosistemi acquatici e pesci. Agli esperti è stato chiesto di individuare i temi focali più rappresentativi per la loro disciplina e di assegnare in modo comparativo un valore naturalistico di aree diverse del territorio provinciale. La metodologia adottata, basata sull'ottenimento delle informazioni dirette da parte dei maggiori esperti presenti sul territorio, è stata integrata per porzioni del territorio poco esplorato con un'analisi in ambiente GIS sulla base di database dell'uso del suolo e delle pressioni antropiche. Questo ha permesso di cartografare le aree più importanti per la conservazione della biodiversità. La gap analysis delle Aree prioritarie con le Aree protette e con altre categorie di tutela del territorio già presenti (parchi e riserve naturali, SIC, ZPS), ha permesso di valutare l'efficacia di queste seconde per la conservazione della biodiversità. Le Aree prioritarie sono state effettivamente localizzate quasi totalmente ma non esclusivamente in Aree protette. Tuttavia, l'insieme delle Aree protette del territorio novarese escludeva porzioni significative di territori di elevato valore per la biodiversità, ora meglio definiti con questa ricerca

    BACKGROUND: Non-invasive vagus nerve stimulation (nVNS) has been shown to be practical, safe, and well tolerated for treating primary headache disorders. The recent multicenter, randomized, double-blind, sham-controlled PRESTO trial provided Class I evidence that for patients with episodic migraine, nVNS significantly increases the probability of having mild pain or being pain-free 2 h post stimulation. We report additional pre-defined secondary and other end points from PRESTO that demonstrate the consistency and durability of nVNS efficacy across a broad range of outcomes. METHODS: After a 4-week observation period, 248 patients with episodic migraine with/without aura were randomly assigned to acute treatment of migraine attacks with nVNS (n = 122) or a sham device (n = 126) during a double-blind period lasting 4 weeks (or until the patient had treated 5 attacks). All patients received nVNS therapy during the subsequent 4-week/5-attack open-label period. RESULTS: The intent-to-treat population consisted of 243 patients. The nVNS group (n = 120) had a significantly greater percentage of attacks treated during the double-blind period that were pain-free at 60 (P = 0.005) and 120 min (P = 0.026) than the sham group (n = 123) did. Similar results were seen for attacks with pain relief at 60 (P = 0.025) and 120 min (P = 0.018). For the first attack and all attacks, the nVNS group had significantly greater decreases (vs sham) in pain score from baseline to 60 min (P = 0.029); the decrease was also significantly greater for nVNS at 120 min for the first attack (P = 0.011). Results during the open-label period were consistent with those of the nVNS group during the double-blind period. The incidence of adverse events (AEs) and adverse device effects was low across all study periods, and no serious AEs occurred. CONCLUSIONS: These results further demonstrate that nVNS is an effective and reliable acute treatment for multiple migraine attacks, which can be used safely while preserving the patient's option to use traditional acute medications as rescue therapy, possibly decreasing the risk of medication overuse. Together with its practicality and optimal tolerability profile, these findings suggest nVNS has value as a front-line option for acute treatment of migraine.
