الوصف: OBJECTIVE: Modeling the effect of meal composition on glucose excursion would help in designing decision support systems (DSS) for type 1 diabetes (T1D) management. In fact, macronutrients differently affect post-prandial gastric retention (GR), rate of appearance (R[Formula: see text]), and insulin sensitivity (S[Formula: see text]). Such variables can be estimated, in inpatient settings, from plasma glucose (G) and insulin (I) data using the Oral glucose Minimal Model (OMM) coupled with a physiological model of glucose transit through the gastrointestinal tract (reference OMM, R-OMM). Here, we present a model able to estimate those quantities in daily-life conditions, using minimally-invasive (MI) technologies, and validate it against the R-OMM. METHODS: Forty-seven individuals with T1D (weight =78±13 kg, age =42±10 yr) underwent three 23-hour visits, during which G and I were frequently sampled while wearing continuous glucose monitoring (CGM) and insulin pump (IP). Using a Bayesian Maximum A Posteriori estimator, R-OMM was identified from plasma G and I measurements, and MI-OMM was identified from CGM and IP data. RESULTS: The MI-OMM fitted the CGM data well and provided precise parameter estimates. GR and R[Formula: see text] model parameters were not significantly different using the MI-OMM and R-OMM (p 0.05) and the correlation between the two S[Formula: see text] was satisfactory ( ρ =0.77). CONCLUSION: The MI-OMM is usable to estimate GR, R[Formula: see text], and S[Formula: see text] from data collected in real-life conditions with minimally-invasive technologies. SIGNIFICANCE: Applying MI-OMM to datasets where meal compositions are available will allow modeling the effect of each macronutrient on GR, R[Formula: see text], and S[Formula: see text]. DSS could finally exploit this information to improve diabetes management.

الوصف: open ; Un trattamento antibiotico mirato ed efficace è di vitale importanza per i pazienti ricoverati in terapia intensiva. Le loro gravi condizioni cliniche, spesso in rapida evoluzione, possono compromettere il successo terapeutico della terapia antibiotica. In questo elaborato vengono presentati dei modelli non lineari ad effetti misti della piperacillina, antibiotico comunemente somministrato per il trattamento delle infezioni nei pazienti critici. I modelli mirano a predire l’andamento della concentrazione del farmaco nel tempo, con il fine ultimo di identificare il dosaggio ottimale per questi pazienti. L’obiettivo di questa tesi consiste nell’identificazione dei parametri clinici che influenzano la cinetica della piperacillina e nello studio dell’effetto delle tecniche di depurazione extracorporea sull’eliminazione di questo antibiotico.
