Caratterizzazione della dinamica produttiva di pascoli naturali italiani

This work studies herbage production and its seasonal distribution in indigenous pastures, and analyses the relationship between the environmental factors (soil, clima, vegetation) and the productivity of these resources. The investigations have been carried on during the period 1983-90 by the joint activity of 10 different University Istitutions in 23 different environments distributed along the Italian peninsula and the main islands. For each environment, pasture production has been measured with the Corrall and Fenlon method, analysing the more important vegetational and ecological conditions; altogether the total yearly production and the seasonal pattern of herbage production have been detected on 104 pastures. The total herbage yield is not significantly influenced by the latitudinal gradient, and the overall regional (alps, central Appenine, south Apennine and islands) production is about 2.3 t ha-1 year-1 The wide range (0.5-6.3 t ha-1 year-1) of herbage production, on small or medium scale, seems to be due to evident changeof environmental or management factors. Five types of seasonal distribution of herbage growth are evidenced with multivariate analysis methods, based on the growing season and the amplitude of the growth. With mean temperature above 12°C and total rainfall below 800 mm, herbage distribution shows a standstill during summer period and an evident regrowth in autumn. On the contrary, for the 4 other distribution types, the winter standstill become important, and the types are distinct by summer growth amplitude and by the growing season lenght. With cluster analysis method, for each type of herbage distribution, have been pointed out under-types characterized by interannual herbage production variation. Among the environmental factors, vegetation characheristics, expressed as Pasture Value following Daget and Poissonet seems to be strictly correlated with total production. The comparative poor role played by the soil and climatic factor, may be due to the strong past and present antropic influence, related with management and utilization techniques. Il presente lavoro ha come scopo l'approfondimento delle conoscenze sulla produzione e sulla distribuzione stagionale della crescita dell'erba dei pascoli naturali, nonché l'analisi delle interazioni tra i fattori ambientali, pedo-climatici e vegetazionali, e la risposta produttiva di queste risorse. La ricerca è stata condotta nel periodo 1983-90 da 10 diverse Istituzioni Universitarie, in 23 ambienti differenti, distribuiti lungo tutta la penisola e le isole maggiori. Per ogni ambiente, con il metodo di rilievo di Corrall e Fenlon, è stata saggiata la risposta produttiva di pascoli rappresentativi delle principali situazioni vegetazionali e di giacitura; complessivamente sono state rilevate la produzione totale annua e la curva di produttività media pluriennale di 104 pascoli. Riguardo la produzione annua complessiva si è osservato che essa non presenta variazioni significative lungo il gradiente latitudinale, collocandosi tra le diverse regioni (alpina, centro appenninica, suq, appenninica e insulare) attorno a 2.3 t ha-1 anno-1. La fitomassa raccolta è soggetta invece a variazioni sensibili (0.5-6.3 t ha-1 anno-1) riconducibili a fattori ambientali e gestionali che si esprimono su piccola e media scala. Con metodi di analisi multivariata si sono individuate 5 tipologie distributive della crescita dell'erba, in rapporto alla stagione vegetativa e alle variazioni dell'intensità di crescita nel corso della stagione stessa. Con temperature medie e precipitazioni annue rispettivamente maggiori di 12°C e minori di 800 mm, risulta evidente la stasi vegetativa nel trimestre estivo e la ripresa vegetativa autunnale. Nel caso opposto la stasi è invernale e le 4 tipologie afferenti a questo modello, sono distinguibili dall'entità della crescita nei mesi estivi e dalla durata della stagione vegetativa. Per ogni tipologia produttiva, sono state evidenziate, tramite l'analisi cluster, sotto-tipologie distinte per la variabilità produttiva interannuale. Tra i fattori ambientali, la vegetazione, espressa attraverso l'indice del valore pastorale di Daget e Poissonet, presenta una buona capacità predittiva nei confronti del livello produttivo dei pascoli. Il contributo comparativamente modesto offerto dai fattori pedoclimatici sembra attribuibile alla forte influenza antropica, pregressa e attuale, attraverso le cure colturali e l'utilizzazione

Pretherapeutic dosimetry in patients affected by metastatic thyroid cancer using I-124 PET/CT sequential scans for I-131 treatment planning

Purpose: This study evaluates the use of sequential 124I PET/CT for predicting absorbed doses to metastatic lesions in patients with differentiated thyroid cancer undergoing 131I therapy. Methods: From July 2011 until July 2013, 30 patients with metastatic differentiated thyroid cancer were enrolled. Each participant underwent PET/CT at 4, 24, 48, and 72 hours with 74 MBq of 124I. Blood samples and whole-body exposure measurements were obtained to calculate blood and red marrow doses. Activity concentrations and lesion volumes obtained from PET/CT were used to evaluate tumor doses with medical internal radiation dose formalism and spheres modeling. Mean administered 131I therapeutic dose was 5994 MBq (range, 1953–11,455 MBq). Results: 124I PET/CT demonstrated all lesions detected by posttherapy 131I whole-body scans. Mean dose rates for blood, red marrow, and lesions were as follows: 0.07 ± 0.02 mGy/MBq, 0.05 ± 0.02 mGy/MBq, and 46.5 ± 117 mGy/MBq, respectively. Despite the high level of thyroid-stimulating hormone and CT detectable lesions, 15 of 30 patients did not show any abnormal 124I uptake. Conclusions: The quantitative value of 124I PET/CT allows simple and accurate evaluation of lesion dosimetry following medical internal radiation dose formalism. Negative 124I PET/CT predicts absence of iodine avidity, potentially allowing avoidance of therapeutically ineffective 131I administration

The CANOVA Study Real-World Evidence of Biologic Treatments in Moderate-Severe Psoriasis in Italy: A Gender Perspective

In psoriasis, several studies have indicated sex differences in clinical characteristics, type of treatment, and outcomes. A higher impact of psoriasis on quality of life (QoL) and a lower treatment satisfaction have been reported in women by different authors

Efficacy of cyclosporine a as monotherapy in patients with psoriatic arthritis: A subgroup analysis of the SYNERGY Study

BACKGRO UND: The SYNER GY Study is an observational, multicenter Italian study, conducted in patients with diagnosis of psoriatic arthritis (PsA) treated from at least 3 months with cyclosporine and aimed at assessing patients' seropositivity for viral infections and efficacy and safety of cyclosporine, administered as monotherapy or in combination with other systemic drugs in the routine clinical practice. The aim of this subanalysis of the SYNER GY study was to evaluate the effects of CsA as monotherapy only in PsA over 12 months of observation. MET HOD S: Psoriasis was evaluated by Body Surface Area and the Psoriasis Area Severity Index (PASI). PsA was evaluated by number of swollen and tender joints, painful entheses and fingers with dactylitis, the Bath Ankylosing Spondylitis Activity Index (BASDAI) and by patients' and physicians' global assessment on a 10-point Visual Analogue Scale. RE SULTLTS: Cyclosporine in monotherapy was effective in reducing all the measured disease parameters. The major indexes of cutaneous and spinal involvement, PASI and BASDAI were significantly reduced over the study period, as were the number of swollen and tender peripheral joints, and enthesitis and dactylitis. CONCLUSIONS: Cyclosporine in monotherapy confirmed its efficacy in cutaneous psoriasis and suggested to be effective also on PsA, reducing spinal and peripheral joints' signs and symptoms

Long-term proactive management of psoriasis with calcipotriol and betamethasone dipropionate foam: an Italian consensus through a combined nominal group technique and Delphi approach

none85Background: Although long-term management of psoriasis is paramount, this approach is challenging in clinical practice. In the recent PSO-LONG trial, a fixed-dose combination of betamethasone dipropionate (BD) and calcipotriol (Cal) foam applied twice a week on non-consecutive days for 52 weeks (proactive treatment) reduced the risk of relapse. However, the role of Cal/BD foam in the long-term management of psoriasis needs further clarifications. The ProActive Management (PAM) program, a nationwide Italian project, aims at reaching a consensus on the role of proactive management of psoriasis. Methods: A steering committee generated some statements through the nominal group technique (NGT). The statements were voted by an expert panel in an adapted Delphi voting process. Results: Eighteen statements were proposed, and the majority of them (14/18) reached a consensus during the Delphi voting. The need to provide long-term proactive topical treatment to reduce the risk of relapse for the treatment of challenging diseases sites or in patients where phototherapy or systemic therapies are contraindicated/ineffective was widely recognized. A consensus was reached about the possibility to associate the proactive treatment with systemic and biological therapies, without the need for dose intensification, thus favoring a prolonged remission. Moreover, the proactive treatment was recognized as more effective than weekend therapy in increasing time free from relapses. Approaches to improve adherence, on the other hand, need further investigation. Conclusions: The inclusion in guidelines of a proactive strategy among the effective treatment options will be a fundamental step in the evolution of a mild-moderate psoriasis therapeutic approach.noneDe Simone, Clara; Dapavo, Paolo; Malagoli, Piergiorgio; Martella, Alessandro; Campanati, Anna; Campione, Elena; Errichetti, Enzo; Franchi, Chiara; Gambardella, Alessio; Megna, Matteo; Osti, Federica; Ribero, Simone; Zagni, Giovanni; Calzavara-Pinton, Piergiacomo; Fabbrocini, Gabriella; Amoruso, Giuseppe Fabrizio; Baglieri, Francesco; Biamonte, Anna Silvia; Bianchelli, Tommaso; Bigi, Laura; Bortoli, Jarno; Brunetti, Bruno; Buligan, Cinzia; Cagni, Elisabetta; Calderoni, Ombretta; Calzavara-Pinton, Piergiacomo; Campanati, Anna; Caputo, Alighiero; Carrera, Carlo Giovanni; Carugno, Andrea; Chersi, Karin; Cicchelli, Stefano; De Natale, Flora; De Simone, Clara; Dapavo, Paolo; Di Maria, Domenico; Errichetti, Enzo; Fabbrocini, Gabriella; Ferrari, Angelo Salvatore; Fogli, Emanuela; Forconi, Riccardo; Franchi, Chiara; Galeazzi, Augusto; Gambardella, Alessio; Giovannini, Andrea; Giura, Maria Teresa; Iuculano, Massimo; Lazzaretti, Giuseppe; Leporati, Claudia; Magnanini, Massimiliano; Malagoli, Piergiorgio; Marconi, Barbara; Martella, Alessandro; Maruccia, Adriana; Megna, Matteo; Miglietta, Roberta; Minuti, Anna; Mocci, Luigi; Modica, Sonia; Narcisi, Alessandra; Odorici, Giulia; Osti, Federica; Pazzaglia, Massimiliano; Peila, Rossana; Pertusi, Ginevra; Pezza, Michele; Pezzullo, Elio; Puccia, Nunzio; Raulo, Umberto; Ribero, Simone; Rossi, Mariateresa; Rusignuolo, Sergio; Sapienza, Giada; Savarese, Catello; Scalisi, Mariaelena; Strippoli, Davide; Stroppiana, Elena; Tiberio, Rossana; Trischitta, Antonino; Tucci, Maria Giovanna; Vaira, Fabrizio; Verrone, Anna; Villa, Lucia; Zagni, Fabio; Zoccali, AndreaDe Simone, Clara; Dapavo, Paolo; Malagoli, Piergiorgio; Martella, Alessandro; Campanati, Anna; Campione, Elena; Errichetti, Enzo; Franchi, Chiara; Gambardella, Alessio; Megna, Matteo; Osti, Federica; Ribero, Simone; Zagni, Giovanni; Calzavara-Pinton, Piergiacomo; Fabbrocini, Gabriella; Amoruso, Giuseppe Fabrizio; Baglieri, Francesco; Biamonte, Anna Silvia; Bianchelli, Tommaso; Bigi, Laura; Bortoli, Jarno; Brunetti, Bruno; Buligan, Cinzia; Cagni, Elisabetta; Calderoni, Ombretta; Calzavara-Pinton, Piergiacomo; Campanati, Anna; Caputo, Alighiero; Carrera, Carlo Giovanni; Carugno, Andrea; Chersi, Karin; Cicchelli, Stefano; De Natale, Flora; De Simone, Clara; Dapavo, Paolo; Di Maria, Domenico; Errichetti, Enzo; Fabbrocini, Gabriella; Ferrari, Angelo Salvatore; Fogli, Emanuela; Forconi, Riccardo; Franchi, Chiara; Galeazzi, Augusto; Gambardella, Alessio; Giovannini, Andrea; Giura, Maria Teresa; Iuculano, Massimo; Lazzaretti, Giuseppe; Leporati, Claudia; Magnanini, Massimiliano; Malagoli, Piergiorgio; Marconi, Barbara; Martella, Alessandro; Maruccia, Adriana; Megna, Matteo; Miglietta, Roberta; Minuti, Anna; Mocci, Luigi; Modica, Sonia; Narcisi, Alessandra; Odorici, Giulia; Osti, Federica; Pazzaglia, Massimiliano; Peila, Rossana; Pertusi, Ginevra; Pezza, Michele; Pezzullo, Elio; Puccia, Nunzio; Raulo, Umberto; Ribero, Simone; Rossi, Mariateresa; Rusignuolo, Sergio; Sapienza, Giada; Savarese, Catello; Scalisi, Mariaelena; Strippoli, Davide; Stroppiana, Elena; Tiberio, Rossana; Trischitta, Antonino; Tucci, Maria Giovanna; Vaira, Fabrizio; Verrone, Anna; Villa, Lucia; Zagni, Fabio; Zoccali, Andre

The GENDER ATTENTION Observational Study: Gender and Hormonal Status Differences in the Incidence of Adverse Events During Cyclosporine Treatment in Psoriatic Patients

INTRODUCTION: Female sex has been shown to be a risk factor for the development of adverse drug reactions; however, this has not been studied for cyclosporine (CsA). The aim of this study was to investigate, in Italian dermatological practice, the influence of gender and menopause and related hormones on the incidence of adverse events (AEs) during CsA treatment in psoriatic patients. METHODS: Multicenter, prospective, observational study conducted from May 2011 to June 2013. Patients with plaque psoriasis, undergoing a new CsA administration course, or about to start it, were enrolled in the outpatient clinics of Italian dermatological centers. During the 2-6 months of study duration, patients had to note all AEs that occurred in a diary that was reviewed by the investigators at the follow-up visit. Sex hormone levels were measured within 7 days from the start date of a menstrual cycle. RESULTS: A total of 969 adult psoriatic patients were enrolled in the study, divided into four cohorts: fertile women and corresponding age-matched men; postmenopausal women and corresponding age-matched men. A significant difference in the percentage of patients with AEs was observed between fertile and postmenopausal women, but not between women and age-matched men. AE incidence rate was about 37% higher in fertile women than in age-matched men and about 18% higher in postmenopausal women than in age-matched men, but differences were not statistically significant. Incidence rate ratio of fertile vs. postmenopausal women was 0.67, reaching statistical significance. AEs were mild or moderate in severity in the great majority of patients of all cohorts and postmenopausal women had significantly less grade 1-2 AEs compared to fertile women, but more grade 3-4 AEs. FSH levels were significantly higher in postmenopausal women reporting no AEs, and DHEA sulfate levels were about 10% higher in men with no AEs, compared to those reporting at least one AE. Cortisol levels were slightly though significantly higher in postmenopausal women with no AE. CONCLUSIONS: A better understanding of sex- and hormone-related influences on drug responses may help to improve drug safety and efficacy, by permitting one to tailor pharmacological treatments to individual subjects or defined patient cohorts
