[EN] Minimally or noninvasive continuous glucose monitors estimate plasma glucose from compartments alternative to blood, and may revolutionize the management of diabetes. However, the accuracy of current devices is still ...
Artificial Pancreas System With Unannounced Meals Based on a Disturbance Observer and Feedforward Compensation

Sanz Diaz, Ricardo; García Gil, Pedro José; Diez, José-Luís; Bondía Company, Jorge (Institute of Electrical and Electronics Engineers, 2021-01)

[EN] This brief is focused on the closed-loop control of postprandial glucose levels of patients with type 1 diabetes mellitus after unannounced meals, which is still a major challenge toward a fully autonomous artificial ...
Automatic Adaptation of Basal Insulin using Sensor-augmented Pump Therapy

Herrero, Pau; Bondía Company, Jorge; Giménez, M.; Oliver, Nick; Georgiou, Pantelis (SAGE Publications, 2018-03-01)

[EN] Background: People with insulin-dependent diabetes rely on an intensified insulin regimen. Despite several guidelines, they are usually impractical and fall short in achieving optimal glycemic outcomes. In this work, ...
Calculation of the Best Basal-Bolus Combination for Postprandial Glucose Control in Insulin Pump Therapy

Revert, Ana; Calm, Remei; Vehí, Josep; Bondía Company, Jorge (Institute of Electrical and Electronics Engineers, 2011-02)

[EN] Intensive insulin therapy in type 1 diabetes is based on the well-established practice of adjusting basal and bolus insulin independently. Basal insulin delivery is designed to optimize glucose concentrations between ...
Comparison of interval and Monte Carlo simulation for the prediction of postprandial glucose under uncertainty in type 1 diabetes mellitus

Calm, R.; García-Jaramillo, M.; Bondía Company, Jorge; Sainz, M.A.; Vehí, J. (Elsevier, 2011-12)

[EN] In this paper, the problem of tackling uncertainty in the prediction of postprandial blood glucose is analyzed. Two simulation approaches, Monte Carlo and interval models, are studied and compared. Interval simulation ...
Experimental blood glucose interval identification of patients with type 1 diabetes

Laguna Sanz, Alejandro José; Rossetti, Paolo; Ampudia Blasco, F. Javier; Vehí, Josep; Bondía Company, Jorge (Elsevier, 2014-01)

[EN] Many problems are confronted when characterizing a type 1 diabetic patient such as model mismatches, noisy inputs, measurement errors and huge variability in the glucose profiles. In this work we introduce a new ...
Extensive assessment of blood glucose monitoring during postprandial period and its impact on closed-loop performance

Biagi, L.; Hirata-Bertachi, A.; Conget, I.; Quirós, C.; Giménez, M.; Ampudia-Blasco, F.J.; Rossetti, P.; Bondía Company, Jorge; Vehí, J. (SAGE Publications, 2017-11)

[EN] Background: Closed-loop (CL) systems aims to outperform usual treatments in blood glucose control and continuous glucose monitors (CGM) are a key component in such systems. Meals represents one of the main disturbances ...
Individual Categorisation of Glucose Profiles Using Compositional Data Analysis

Biagi, L.; Bertachi, A.; Giménez, M.; Conget, I.; Bondía Company, Jorge; Martín-Fernández, Josep Antoni; Vehí, Josep (SAGE Publications, 2019-12-01)

[EN] The aim of this study was to apply a methodology based on compositional data analysis (CoDA) to categorise glucose profiles obtained from continuous glucose monitoring systems. The methodology proposed considers ...
Insulin dosage optimization based on prediction of postprandial glucose excursions under uncertain parameters and food intake

García Jaramillo, Maira Alejandra; Calm, R.; Bondía Company, Jorge; Tarin, C.; Vehi, J. (Elsevier, 2012-01)

Considering the difficulty in selecting correct insulin doses and the problem of hyper- and hypoglycemia episodes in type 1 diabetes, dosage-aid systems are very useful for these patients. A model-based approach to this ...
