    Il progetto si è posto l’obiettivo di implementare le competenze trasversali degli studenti nell’ambito della divulgazione scientifica, attraverso un percorso avviato con lo studio della zoologia e proseguito con attività di comunicazione e guida museale, mantenendo uno spirito collaborativo tra i tutor, il personale del Museo e i giovani. Nel contesto museale, dove un elevato numero di forme animali è concentrato in uno spazio ristretto, gli studenti hanno “toccato con mano” la varietà di specie esistenti, percepita in maniera immediata ed emotivamente significativa. Hanno così imparato ad applicare le metodologie per classificare gli animali e denominarli, integrando, in diversi momenti, l’uso della lingua inglese. Gli studenti hanno poi trasferito praticamente i contenuti acquisiti in un lavoro di ideazione, progettazione e realizzazione di prodotti didattico-divulgativi, presentati in un evento di grande impatto sul territorio della città di Palermo: la “Notte europea dei musei” 2018

    Monoclonal antibodies for the treatment of non-haematological tumours: Update of an expanding scenario

    Get PDF
    Introduction: The identification of cell membrane-bound molecules with a relevant role in cancer cell survival prompted the development of moAbs to block the related pathways. In the last few years, the number of approved moAbs for cancer treatment has constantly increased. Many of these drugs significantly improved the survival outcomes in patients with solid tumours.Areas covered: In this review, all the FDA-approved moAbs in solid tumours have been described. This is an update of moAbs available for cancer treatment nowadays in comparison with the moAbs approved until few years ago. The moAbs under development are also discussed here.Expert opinion: The research on cancer antigens as therapeutic targets led to an expanding scenario of available treatment options in non-haematological malignancies. In a few years, the number of approved drugs has increased rapidly. Some of these agents are actually on label in combination with standard chemotherapy. Only some of them can be delivered as monotherapy. The research on these new drugs is addressing both the identification of further target molecules in key cancer-related pathways and the improvement of drug effectiveness by changing the affinity and the selectivity of a moAb relative to its target

    Secondary malignancies after high-dose chemotherapy in germ cell tumor patients: A 34-year retrospective study of the European Society for Blood and Marrow Transplantation (EBMT)

    We aimed to assess the incidence and risk factors of secondary malignancy (SM) in the young adult patients who received high-dose chemotherapy (HDCT) for germ cell tumors (GCT). The EBMT database was interrogated. Criteria for patient selection included adult male GCT and HDCT administered in any line of therapy. Cumulative incidence methods were used to estimate the time-to-SM diagnosis. Univariable Fine and Gray proportional hazard regression evaluated risk factors of SM occurrence. From 1981 to 2015, 9153 autografts were identified. Among 5295 patients, 59 cases of SM, developed after a median follow-up of 3.8 years, were registered. Of these patients, 23 (39%) developed hematologic SM, 34 (57.6%) solid SM (two patients had uncoded SM). Twenty-year cumulative incidence of solid versus hematologic SM was 4.17% (95% CI: 1.78-6.57) versus 1.37% (95% CI: 0.47-2.27). Median overall survival after SM was significantly shorter for patients who developed hematologic SM versus solid SM (8.6 versus 34.4 months, p = 0.003). Age older than 40 years at the time of HDCT was significantly associated with hematologic, but not solid, SM development (p = 0.004 versus p = 0.234). SM occurrence post-HDCT showed different patterns of incidence and mortality in GCT. These data may be important to optimize patient selection, counseling and follow-up after HDCT

    Weighing the prognostic role of hyponatremia in hospitalized patients with metastatic solid tumors: the HYPNOSIS study

    Previous works linked low sodium concentration with mortality risk in cancer. We aimed at weighing the prognostic impact of hyponatremia in all consecutive patients with metastatic solid tumors admitted in a two-years period at our medical oncology department. Patients were included in two cohorts based on serum sodium concentration on admission. A total of 1025 patients were included, of whom 279 (27.2%) were found to be hyponatremic. The highest prevalence of hyponatremia was observed in biliary tract (51%), prostate (45%) and small-cell lung cancer (38.9%). With a median follow-up of 26.9 months, median OS was 2 months and 13.2 months for the hyponatremia versus control cohort, respectively (HR, 2.65; P < 0.001). In the multivariable model, hyponatremia was independently associated with poorer OS (HR, 1.66; P < 0.001). According to the multivariable model, a nomogram system was developed and validated in an external set of patients. We weighed over time the influence of hyponatremia on survival of patients with metastatic solid tumors and pointed out the possibility to exploit serum sodium assessment to design integrated prognostic tools. Our study also highlights the need for a deeper characterization of the biological role of extracellular sodium levels in tumor development and progression

    SYT-SSX fusion genes and prognosis in synovial sarcoma

    Get PDF
    A case series of 64 synovial sarcomas was characterized for the SYT-SSX fusion transcripts and statistically analysed in order to correlate molecular data with prognosis and morphology. SYT-SSX1 fusion transcript appeared to be an independent, though not reaching statistical significance (P = 0.183), prognostic factor clearly associated with a reduced metastasis-free survival. Regarding the association between transcript type and histologic subtype we found, a borderline P value (P = 0.067) between the SYT-SSX1 transcript and the biphasic subtype which, subsequently expanding the analysis to 70 cases, turned out to be significant. However, we could not confirm the prediction value of the biphasic subtype for the presence of the SYT-SSX1 transcript since in our hands 6 out 33 (18%) biphasic tumours carried the SYT-SSX2 transcript.© 2001 Cancer Research Campaign  http://www.bjcancer.co

    Natalizumab affects T-cell phenotype in multiple sclerosis: implications for JCV reactivation

    Get PDF
    The anti-CD49d monoclonal antibody natalizumab is currently an effective therapy against the relapsing-remitting form of multiple sclerosis (RRMS). Natalizumab therapeutic efficacy is limited by the reactivation of the John Cunningham polyomavirus (JCV) and development of progressive multifocal leukoencephalopathy (PML). To correlate natalizumab-induced phenotypic modifications of peripheral blood T-lymphocytes with JCV reactivation, JCV-specific antibodies (serum), JCV-DNA (blood and urine), CD49d expression and relative abundance of peripheral blood T-lymphocyte subsets were longitudinally assessed in 26 natalizumab-treated RRMS patients. Statistical analyses were performed using GraphPad Prism and R. Natalizumab treatment reduced CD49d expression on memory and effector subsets of peripheral blood T-lymphocytes. Moreover, accumulation of peripheral blood CD8+ memory and effector cells was observed after 12 and 24 months of treatment. CD4+ and CD8+ T-lymphocyte immune-activation was increased after 24 months of treatment. Higher percentages of CD8+ effectors were observed in subjects with detectable JCV-DNA. Natalizumab reduces CD49d expression on CD8+ T-lymphocyte memory and effector subsets, limiting their migration to the central nervous system and determining their accumulation in peripheral blood. Impairment of central nervous system immune surveillance and reactivation of latent JCV, can explain the increased risk of PML development in natalizumab-treated RRMS subjects

    Gender Asymmetry in Okun's Law in the Four PIGS Countries

    Get PDF
    AbstractCentred on the four PIGS countries (Portugal, Italy, Greece and Spain) and using the quarterly data from Q2/1998 until Q4/2014, the paper investigates whether there exists gender asymmetries in Okun's law and whether male unemployment reacts identically to economic fluctuations as female unemployment does. Whilst the trend components of output, male and female unemployment are estimated with the aid of the HP filter, Okun's relationships are modelled in the SVAR framework assuming that cyclical fluctuations of the economy and the labour market with both male and female labour force are endogenous. It is established that gender is indeed a factor that makes the respective segments of the labour market respond slightly differently to changes in real output
