L’attività nel teatro della Villa medicea di Pratolino, presso Firenze, giunse al culmine nel primo decennio del ’700, quando il principe Ferdinando de’ Medici commissionò e vi fece rappresentare, una per anno, opere in musica di Alessandro Scarlatti e di Giacomo Antonio Perti. Benché le partiture siano perdute, sopravvive un’ingente quantità di materiale documentario, in massima parte inedito, il quale dà un eccezionale resoconto sul mecenatismo del Principe e sul funzionamento della macchina teatrale. La dissertazione si concentra sulle sei opere poste in musica da Perti ("Lucio Vero", 1700, in collaborazione con Martino Bitti; "Astianatte", 1701; "Dionisio re di Portogallo", 1707; "Ginevra principessa di Scozia", 1708; "Berenice regina d’Egitto", 1709; "Rodelinda regina de’ Longobardi", 1710), sui rapporti del compositore col Principe, col librettista Antonio Salvi, col rivale Scarlatti, coi cantanti e con la corte medicea, sullo stile da lui perseguito e – per quanto è dato sapere o lecito ipotizzare – sulla fisionomia dei suoi lavori (strutture e risorse letterarie, teatrali e musicali).

Neurodevelopment of preterm children has become an outcome of major interest since the improvement in survival due to advances in neonatal care. Many studies focused on the relationships among prenatal characteristics and neurodevelopmental outcome in order to identify the higher risk preterms’ subgroups. The aim of this study is to analyze and put in relation growth and development trajectories to investigate their association. 346 children born at the S.Orsola Hospital in Bologna from 01/01/2005 to 30/06/2011 with a birth weight of <1500 grams were followed up in a longitudinal study at different intervals from 3 to 24 months of corrected age. During follow-up visits, preterms’ main biometrical characteristics were measured and the Griffiths Mental Development Scale was administered to assess neurodevelopment. Latent Curve Models were developed to estimate the trajectories of length and of neurodevelopment, both separately and combined in a single model, and to assess the influence of clinical and socio-economic variables. Neurodevelopment trajectory was stepwise declining over time and length trajectory showed a steep increase until 12 months and was flat afterwards. Higher initial values of length were correlated with higher initial values of neurodevelopment and predicted a more declining neurodevelopment. SGA preterms and those from families with higher status had a less declining neurodevelopment slope, while being born from a migrant mother proved negative on neurodevelopment through the mediating effect of a being taller at 3 months. A longer stay in NICU used as a proxy of preterms’ morbidity) was predictive of lower initial neurodevelopment levels. At 24 months, neurodevelopment is more similar among preterms and is more accurately evaluated. The association among preterms’ neurodevelopment and physiological growth may provide further insights on the determinants of preterms’ outcomes. Sound statistical methods, exploiting all the information collected in a longitudinal study, may be more appropriate to the analysis.
