The combination of cardiac pathology and metabolic disorders, namely type 2 diabetes mellitus, is one of the most frequent comorbid pathologies and the main cause of death from cardiovascular complications at an early stage of the disease. Despite the wide range of antithrombogenic measures, prevention of thrombotic complications of acute myocardial infarction remains an urgent problem of cardiology. The study involved examination of 73 patients with acute myocardial infarction with concomitant type 2 diabetes mellitus, who were distributed into clusters according to severity by the main indices of lipid and carbohydrate metabolism using hierarchical analysis...

OBJECTIVE: Short-term intensive insulin therapy (IIT) early in the course of type 2 diabetes acutely improves beta-cell function with long-lasting effects on glycemic control. However, conventional measures cannot determine which patients are better suited for IIT, and little is known about the molecular mechanisms determining response. Therefore, this study aimed to develop a model that could accurately predict the response to IIT and provide insight into molecular mechanisms driving such response in humans...

BACKGROUND: A 75-g oral glucose tolerance test (OGTT) provides important information about glucose metabolism, although the test is expensive and invasive. Complete OGTT information, such as 1-hour and 2-hour postloading plasma glucose and immunoreactive insulin levels, may be useful for predicting the future risk of diabetes or glucose metabolism disorders (GMD), which includes both diabetes and prediabetes. OBJECTIVE: We trained several classification models for predicting the risk of developing diabetes or GMD using data from thousands of OGTTs and a machine learning technique (XGBoost)...

BACKGROUND: The amount of insulin needed to effectively treat type 2 diabetes worldwide is unknown. It also remains unclear how alternative treatment algorithms would affect insulin use and disability-adjusted life-years (DALYs) averted by insulin use, given that current access to insulin (availability and affordability) in many areas is low. The aim of this study was to compare alternative projections for and consequences of insulin use worldwide under varying treatment algorithms and degrees of insulin access...

Adaptive and personalized model predictive control (MPC) algorithms that explicitly consider insulin dosing constraints are necessary to prevent overdose-induced hypoglycemia in type 1 diabetes. A personalized plasma insulin concentration (PIC) estimator is integrated with adaptive models to characterize the temporal dynamics of PIC and blood glucose concentration (BGC). The dynamic profile trajectories of the PIC and BGC are used to adapt the control problems and constraints on-line to accurately reflect the concurrent metabolic state of the individuals and improve glucose regulation...

The development of continuous glucose monitoring and insulin control algorithms have enabled the recent development of closed-loop artificial pancreas technology. However, despite these advancements, glucose sensor accuracy and reliability under physiologic conditions and over long periods of monitoring continue to be limiting factors in achieving a truly closed-loop artificial pancreas. To develop improved sensor technology, glucose sensor dynamics and performance need to be modeled accurately under physiologic conditions...

Accurate estimation of food's macronutrient content for people with Diabetes Mellitus (DM) is of great importance, as it determines postprandial insulin dosage. This paper introduces a classification system for food images that is adjusted to the nutritional needs of people with DM. A two-level image classification scheme, exploiting Convolutional Neural Networks (CNNs), is proposed, in order to classify an image in one of eight broad food categories with similar macronutrient content and then assign it to a specific food within that category...

Insulin injection relies on strict blood glucose monitoring. However, existing techniques and algorithms for blood glucose monitoring cannot be completed in a timely way. In this study, we have developed a new intelligent glucose-sensitive insulin delivery system to stabilize blood glucose levels in the body. This system does not require real-time detection of blood glucose. First, we successfully synthesized a nanoscale material called PAM-PAspPBA- b -PEG by using chemical methods. We then conducted TEM, DLS, and ¹H-NMR analyses to characterize the physicochemical properties, such as size, molecular composition, and configuration of the nanomaterial...

The non-alcoholic fatty liver disease (NAFLD) as a common metabolic disease affects nearly one third of the population in the developed countries. The significance of the NAFLD is due to its spectrum disease (simple steatosis → NASH [non-alcoholic steatohepatitis] ± fibrosis → cirrhosis → HCC [hepatocellular carcinome]) character; its association with obesity, type 2 diabetes mellitus (T2DM), dyslipidaemia, metabolic syndrome, insulin resistance; and its complications both as a consequence of the direct progression of the liver disease and also related to the additional target organ damage due to the progression of the metabolic disease (cardiovascular, renal)...

Our objective is to develop a physiology-based model of insulin kinetics to understand how exercise alters insulin concentrations in those with type 1 diabetes (T1D). We reveal the relationship between the insulin absorption rate ([Formula: see text]) from subcutaneous tissue, the insulin delivery rate ([Formula: see text]) to skeletal muscle, and two physiological parameters that characterize the tissue: the perfusion rate (Q) and the capillary permeability surface area (PS), both of which increase during exercise because of capillary recruitment...

Continuous glucose monitoring (CGM) systems are most important in the current Type I diabetes care and as component for the development of artificial pancreas systems because the amount of insulin being supplied is calculated based on the CGM results. Therefore, to stably and accurately control the blood glucose level, CGM should be stable and accurate for a long period. We have been engaged in the biomolecular engineering and application of FAD dependent glucose dehydrogenase complex (FADGDH) which is capable of direct electron transfer...

The hybrid closed-loop insulin delivery system, a form of "artificial pancreas," is composed of an insulin pump, a standardized algorithm, and a continuous glucose monitor. The system streamlines insulin delivery by connecting continuous glucose monitor data with an insulin pump and an algorithm to drive basal insulin delivery. The hybrid closed-loop insulin delivery system, approved by the Food and Drug Administration in 2016 for children older than 7 years, is a major improvement in the management of type 1 diabetes...

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 complete daily glucose profiles obtained from six patients with type 1 diabetes (T1D) who had their glucose monitored for eight weeks. The glucose profiles were distributed into the time spent in six different ranges. The time in one day is finite and limited to 24 h, and the times spent in each of these different ranges are co-dependent and carry only relative information; therefore, CoDA is applied to these profiles...
