Povzetek: Introduction: The global burden of diabetes mellitus is escalating, and more efficient investigative strategies are needed for a deeper understanding of underlying pathophysiological mechanisms. The crucial role of skeletal muscle in carbohydrate and lipid metabolism makes it one of the most susceptible tissues to diabetes-related metabolic disorders. In tissue studies, conventional histochemical methods have several technical limitations and have been shown to inadequately characterise the biomolecular phenotype of skeletal muscle to provide a holistic view of the pathologically altered proportions of macromolecular constituents. Materials and methods: In this pilot study, we examined the composition of five different human skeletal muscles from male donors diagnosed with type 2 diabetes and non-diabetic controls. We analysed the lipid, glycogen, and collagen content in the muscles in a traditional manner with histochemical assays using different staining techniques. This served as a reference for comparison with the unconventional analysis of tissue composition using Fourier-transform infrared spectroscopy as an alternative methodological approach. Results: A thorough chemometric post-processing of the infrared spectra using a multi-stage spectral decomposition allowed the simultaneous identification of various compositional details from a vibrational spectrum measured in a single experiment. We obtained multifaceted information about the proportions of the different macromolecular constituents of skeletal muscle, which even allowed us to distinguish protein constituents with different structural properties. The most important methodological steps for a comprehensive insight into muscle composition have thus been set and parameters identified that can be used for the comparison between healthy and diabetic muscles. Conclusion: We have established a methodological framework based on vibrational spectroscopy for the detailed macromolecular analysis of human skeletal muscle that can effectively complement or may even serve as an alternative to histochemical assays. As this is a pilot study with relatively small sample sets, we remain cautious at this stage in drawing definitive conclusions about diabetes-related changes in skeletal muscle composition. However, the main focus and contribution of our work has been to provide an alternative, simple and efficient approach for this purpose. We are confident that we have achieved this goal and have brought our methodology to a level from which it can be successfully transferred to a large-scale study that allows the effects of diabetes on skeletal muscle composition and the interrelationships between the macromolecular tissue alterations due to diabetes to be investigated.

Incidence and control of steroid-induced hyperglycaemia in hospitalised patients at a tertiary care centre for lung diseases
Matej Dobravc Verbič, Jasna Gruban, Mojca Kerec Kos, 2021, izvirni znanstveni članek

Povzetek: Background The aim of this study was to determine the incidence of steroid-induced hyperglycaemia (SIH) in patients hospitalised at the tertiary centre for lung diseases, to assess glycaemic control during hospitalisation, and to determine the factors associated with the control of SIH. Methods A 4-month retrospective study was conducted. All patients who received systemic glucocorticoids for%%%2 days during hospitalisation, with%%%2 elevated blood glucose (BG) readings, were included in the analysis. SIH control was determined by mean BG levels, the number and proportion of elevated and pronouncedly elevated BG readings, and the number of hypoglycaemic events. Results 60 of 283 patients (21.2%) developed SIH, of which 55 patients were included in further analysis. Mean fasting and daytime BG levels were 7.8%%%2.9 mmol/l and 10.9%%%2.2 mmol/l, respectively. 41/55 patients (74.5%) had elevated average BG levels. 45/55 patients (81.8%) had%>%5 readings or%>%20% of all readings exceeding hyperglycaemia threshold, and 33/55 patients (60.0%) had pronouncedly elevated BG levels on more than one occasion. 6/55 patients (10.9%) experienced more than one hypoglycaemic event or a severe hypoglycaemia. Only 9/55 patients (16.4%) achieved adequate SIH control according to all defined criteria. Pre-existing diabetes and longer duration of hospital treatment with low glucocorticoid dose were significantly associated with poorer glycaemic control (p%<%0.001 and p%=%0.003, respectively). Conclusions Appropriate SIH management was demonstrated to be challenging. According to the defined criteria, adequate glycaemic control during hospitalisation was not achieved in the large majority of patients with SIH.

Continuous glucose monitoring use and glucose variability in pre-school children with type 1 diabetes
Klemen Dovč, Kevin Cargnelutti, Anže Šturm, Julij Šelb, Nataša Bratina, Tadej Battelino, 2018, izvirni znanstveni članek

Povzetek: Aims. The objective of this nationwide population-based cohort study was to evaluate the correlation between continuous glucose monitoring (CGM) use and glucose variability in pre-schoolers with type 1 diabetes. Methods. We analysed data from the Slovenian National Registry. The primary endpoint was the difference in glucose variability between periods, during which participants were using CGM and periods, during which CGM was not used, over 5 years. Results. A total of 40 children <8 years old were followed for an estimated observational period of 116 patient/years. Mean age at CGM initiation was 3.5 (±1.7) years. Both standard deviation of mean glucose [3.6 mmol/L (3.2–3.9) with CGM and 4.3 mmol/L (3.8–4.7) without CGM, p < 0.001] and coefficient of variation [44.0% (40.4–47.0) with CGM and 46.1% (42.3–49.4) without CGM, p = 0.021] were lower during the periods, when CGM was used. Frequent CGM use (>5 days/week) was associated with a 0.4% [4.4 mmol/mol] reduction in glycated haemoglobin level (7.6% compared to 7.2%, p = 0.047). Conclusions. Our results indicate that the use of CGM was associated with reduced glucose variability during a 5 year follow-up period among pre-schoolers with type 1 diabetes.
