AB  - We examine the significance of the predictive potential of EPI cystatin C (EPI CysC) in combination with NTproBNP, sodium, and potassium in the evaluation of renal function in patients with cardiorenal syndrome using standard mathematical classification models from the domain of artificial intelligence. The criterion for the inclusion of subjects with combined impairment of heart and kidney function in the study was the presence of newly discovered or previously diagnosed clinically manifest cardiovascular disease and acute or chronic kidney disease in different stages of evolution. In this paper, five standard classifiers from the field of machine learning were used for the analysis of the obtained data: ensemble of neural networks (MLP), ensemble of k-nearest neighbors (k-NN) and naive Bayes classifier, decision tree, and a classifier based on logistic regression. The results showed that in MLP, k-NN, and naive Bayes, EPI CysC had the highest predictive potential. Thus, our approach with utility classifiers recognizes the essence of the disorder in patients with cardiorenal syndrome and facilitates the planning of further treatment.

AB  - Acute kidney injury is a syndrome that occurs in different clinical situations, under the influence of different risk factors, in patients of all ages, especially those in the intensive care unit. The problem of acute kidney damage refers to numerous clinical situations, different disease mechanisms and poor outcomes. In addition, with the current definition of acute kidney injury, only one conventional marker is available for diagnosis in daily clinical practice. To recognize the disease promptly and start treatment, and thereby improving the outcome, the paper presents a model for recognizing acute kidney damage in the stage that requires hemodialysis treatment.The study included 86 hospitalized patients with acute renal impairment who were divided according to the stage of renal impairment at admission to hospital treatment into three groups. The assessment of acute renal impairment and the classification of disease stages were based on the diagnostic stages by the K / DIGO group. All examined patients were over 18 years of age. In the first stage of the disease it was 12.79%, in the second stage it was 15.12%, and in the third 72.09% of patients. Test methods included clinical processing, laboratory evaluation, functional tests, and echosonographic examination. Clinical data included demographic, comorbidity and vital parameters, baseline full blood count, biochemistry and renal function tests. Further laboratory investigations were performed as indicated clinically thereafter. Spot blood and urine samples were collected from all patients in the morning after overnight fasting. The neural network was created in feed forward back propagation of the connection between the data of 69 patients with 31 parameters. In pattern recognition, the neural network learns to recognize the conditions in which it was decided to send the patient to dialysis 10 or to send to classical treatment 01. The training function analyzed the patients separated in three special categories 80% training, 10% test and 10% validation. The algorithm of the learning function is a scaling gradient that adapts the input data to the output data.The neural network achieved a performance of 0.14322 in 6 epochs. In a test with the data of 17 patients, it was shown that the neural network indicates for which patients dialysis treatment is a better option that fits with AKI stage 3. For patients with the first and second stages of the disease, conservative treatment is a better therapeutic choice.This paper deals with a current topic by analyzing data using a neural network algorithm to help assess the stage of the disease in high-risk hospitalized patients with acute kidney injury and select treatment modalities. The conclusions derived from this analysis should help with stage recognition and the selection of treatment modalities for patients with acute kidney injury.

AB  - Markers used in everyday clinical practice cannot distinguish between the permanent impairment of renal function. Sodium and potassium values and their interdependence are key parameters in addition to volemia for the assessment of cardiorenal balance. The aim of this study was to investigate volemia and electrolyte status from a clinical cardiorenal viewpoint under consideration of renal function utilizing artificial intelligence. In this paper, an analysis of five variables: B-type natriuretic peptide, sodium, potassium, ejection fraction, EPI creatinine-cystatin C, was performed using an algorithm based on the adaptive neuro fuzzy inference system. B-type natriuretic peptide had the greatest influence on the ejection fraction. It has been shown that values of both Na+ and K+ lead to deterioration of the condition and vital endangerment of patients. To identify the risk of occurrence, the model identifies a prognostic biomarker by random regression from the total data set. The predictions obtained from this model can help optimize preventative strategies and intensive monitoring for patients identified as at risk for electrolyte disturbance and hypervolemia. This approach may be superior to the traditional diagnostic approach due to its contribution to more accurate and rapid diagnostic interpretation and better planning of further patient treatment

AB  - The paper presents a generalized model of the photothermal response of a polymer sample. The model is based on a linear non-Fourier heat conduction equation that considers thermal memory and complex heat capacity. The physical meaning of imaginary heat capacity is discussed from the point of view of non-equilibrium thermodynamics. The derived heat conduction equation introduces two additional dynamic properties of a medium to time-varying heat conduction: inertial and kinetic relaxation time. The influence of these relaxation times on photothermal response is analyzed. It is shown that the derived model could explain the measured photoacoustic response of different semi-crystalline polyethylenes (PEs). The obtained results show that photothermal techniques can be employed to estimate relaxation phenomena in polymeric materials when the frequency scale of the experiment is greater than the inverse value of any relaxation time. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
