The existence of two nontrivial solutions for a class of fully nonlinear problems at critical growth with perturbations of lower order is proved. The first solution is obtained via a local minimization argument while the second solution follows by a non-smooth mountain pass theorem.

Objective: First, to assess the impact of the number of examined lymph nodes (ELNs) on staging and survival after distal pancreatectomy (DP) for pancreatic adenocarcinoma (PDAC). Second, to identify the minimum number of ELNs (MNELNs) ensuring an accurate detection of nodal involvement. Third, to reappraise the role of lymph node (LN) parameters, including N-status and lymph node ratio (LNR). Background: In contrast with pancreatoduodenectomy, information on LN staging and the MNELN required in DP is lacking. Methods: Patients undergoing DP for PDAC at 2 academic hospitals from 2000 through 2013 were retrospectively analyzed. The eighth edition of the American Joint Committee on Cancer staging system was used. The MNELN was estimated using the binomial probability law. Survival analyses were performed separately for node-negative and node-positive patients using univariable and multivariable models. Results: The study population consisted of 240 patients. The median number of ELN was 21, significantly lower in node-negative patients as compared with node-positive patients (18.5 vs 24.0; P = 0.001). The proportion of node-positive patients increased with increasing numbers of ELNs, whereas LNR showed an inverse trend. The estimated MNELN was 20. The number of ELN (≥ or <20) was an independent prognostic factor only in node-negative patients [odds ratio (OR) 3.23 for ELN <20), suggesting a stage migration effect. In node-positive patients, N2-class, but not LNR, was a significant predictor of survival at multivariable analysis (OR 1.68). Conclusion: The number of ELN affects nodal staging in body/tail PDAC. At least 20 LNs are required for correct staging. N-status is superior to LNR in predicting survival of node-positive patients.

Si tratta del profilo inedito di un’artista formatosi nella bottega di Bepi Modolo, naturalizzatosi vicentino, frequentata con più assiduità a partire dal 1947 e fino al 1957, anno in cui dà inizio alla sua attività autonoma e matura nuove e determinanti esperienze, frequentando corsi liberi presso l’Accademia di Belle Arti a Venezia, soprattutto prendendo contatti con artisti operanti, ad esempio, in Lombardia, Liguria, il Trentino gardesano. Particolare attenzione ha il riscontro dell’esperienza di lavoro a Stella di Gameragna presso Albissola e della conoscenza di artisti del Gruppo di Corrente che si erano dispersi nel Dopoguerra dando vita a percorsi autonomi. In tali circostanze Bisson ebbe modo di operare le sue scelte estetiche fondamentali che furono, rispetto alla sua stessa formazione, affatto autonome. Quelle in seguito attuate e vagliate su più linee tematiche nell’ambito strettamente del figurativo.
