Blood plasma samples are obtained from type 2 diabetes (T2D) patients and a concentration of F2-isoprostanes (F2I) in the sample is quantified. Plasma F2I levels assess oxidative stress levels in the patient and indicate elevated risk of T2D-associated complications including incident clinical fracture, cardiovascular complications, renal disease, etc. in the T2D cohort, independently of other risk factors. Fracture risk in the T2D population is heightened for a given bone mineral density (BMD) and is underestimated by evaluation tools such as Fracture Risk Assessment Tool (FRAX). The patient's BMD T-score can be adjusted based on F2I concentrations, capturing reductions in bone quality as well as quantity that lead to the elevated fracture risk in T2D patients. These diagnostic procedures can be effectively deployed in a patient's course of treatment merely by supplementing an existing blood panel, rather than with a separate blood draw.

The invention relates to medicine and technology, and more particularly to non-invasively detecting a change in a person's blood glucose concentration, and can be used in the creation of sensors for non-invasively checking a person's blood glucose concentration, as well as in the creation of socially-oriented systems for the early diagnosis of diabetes and associated diseases. The aim of the invention is to improve the operational efficiency of a sensor for a wrist-worn device for non-invasively checking a person's blood glucose concentration by reducing the operational energy consumption of the sensor by virtue of the shape of the inner surface of a rim. The technical result of the invention is that of reducing the operational energy consumption of the sensor. This reduction is achieved by virtue of the shape of the inner surface of a rim, which results in an increase in the amount of light reflected from the arm, and specifically from an artery and other vessels in the arm, and impinging on a light receiver.

Continuous Glucose Monitoring (CGM) devices provide glucose concentration measurements in the subcutaneous tissue with limited accuracy and precision. Therefore, CGM readings cannot be incorporated in a straightforward manner in outcome metrics of clinical trials e.g. aimed to assess new glycemic-regulation therapies. To define those outcome metrics, frequent Blood Glucose (BG) reference measurements are still needed, with consequent relevant difficulties in outpatient settings. Here we propose a “retrofitting” algorithm that produces a quasi continuous time BG profile by simultaneously exploiting the high accuracy of available BG references (possibly very sparsely collected) and the high temporal resolution of CGM data (usually noisy and affected by significant bias). The inputs of the algorithm are: a CGM time series; some reference BG measurements; a model of blood to interstitial glucose kinetics; and a model of the deterioration in time of sensor accuracy, together with (if available) a priori information (e.g. probabilistic distribution) on the parameters of the model. The algorithm first checks for the presence of possible artifacts or outliers on both CGM datastream and BG references, and then rescales the CGM time series by exploiting a retrospective calibration approach based on a regularized deconvolution method subject to the constraint of returning a profile laying within the confidence interval of the reference BG measurements. As output, the retrofitting al
