To date, there is no information about its effect on the specific activity of this class of medicines (anti-inflammatory, analgesic, etc.) in published sources.</p> <p><strong>Objective. </strong>We are aimed to characterize the effect of cryopreserved placenta extract on the anti-inflammatory activity of diclofenac sodium when administered separately in a model of acute exudative inflammation.</p> <p><strong>Methods.</strong> Experimental studies <em>in vivo</em> were conducted on 28 nonlinear male laboratory rats. The model of acute exudative inflammation was reproduced by subplantar injection of 0.1 ml of 1.0% aqueous solution of λ-karagenin into the right hind limb of rats. Cryopreserved placenta extract was administered intramuscularly at a dose of 0.16 ml/kg 60 minutes before diclofenac sodium (8 mg/kg).</p> <p><strong>Results.</strong> Preventive administration of diclofenac sodium caused an antiexudative effect as early as 30 minutes after administration of λ-karagenin – its anti-inflammatory activity was 11.0%, which is 4.6 times higher than similar indicators at the same time in rats injected with placental cryoextract. At 60 minutes of observation, diclofenac sodium was comparable in anti-inflammatory activity with cryopreserved placenta extract: 28.6% and 22.2%, respectively, but at 120 and 180 minutes, diclofenac sodium exceeded the studied cryoextract in antiphlogistic effect by 1.6 times in both periods of observation. The anti-inflammatory effect of the combined separate administration of placenta cryoextract and diclofenac sodium before λ-karagenin for 30 and 60 minutes was 12.7% and 32.3%, respectively, which is comparable with analogous indicators against the background of diclofenac sodium monotherapy. However, at 120 minutes of observation, the group of combined use of placenta cryoextract and diclofenac sodium showed the greatest anti-inflammatory effect among rats of all the studied groups – 52.6%, which was 2.2 times higher than the indicators of the placenta cryoextract monotherapy group and 1.4 times lower than the indicators of the rats of the diclofenac sodium monotherapy group.</p> <p><strong>Conclusions.</strong> 4 hours after administration, placental cryoextract had a suppressive effect on kinins like diclofenac sodium, and in the prostaglandin period of caragenin-induced inflammation against the background of combined use of the studied cryoextract and diclofenac sodium, the anti-inflammatory activity was 46.4 %. This suggests a suppressive effect on the production of prostaglandins as a possible mechanism of anti-exudative action of cryopreserved placenta extract.</p> 2021-09-15T00:00:00+00:00 Copyright (c) 2021 The Author(s) Comparative Analysis of Classification Algorithms in the Analysis of Medical Images From Speckle Tracking Echocardiography Video Data 2021-06-21T15:36:02+00:00 Olena Petrunina Diana Shevaga Vitalii Babenko Volodymyr Pavlov Sergiy Rysin Ievgen Nastenko <p><strong>Background.</strong> Machine learning allows applying various intelligent algorithms to produce diagnostic and/or prognostic models. Such models can be used to determine the functional state of the heart, which is diagnosed by speckle-tracking echocardiography. To determine the patient's heart condition in detail, a classification approach is used in machine learning. Each of the classification algorithms has a different performance when applied to certain situations. Therefore, the actual task is to determine the most efficient algorithm for solving a specific task of classifying the patient's heart condition when applying the same speckle-tracking echocardiography data set.</p> <p><strong>Objective</strong><strong>.</strong> We are aimed to evaluate the effectiveness of the application of prognostic models of logistic regression, the group method of data handling (GMDH), random forest, and adaptive boosting (AdaBoost) in the construction of algorithms to support medical decision-making on the diagnosis of coronary heart disease.</p> <p><strong>Methods</strong><strong>.</strong> Video data from speckle-tracking echocardiography of 40 patients with coronary heart disease and 16 patients without cardiac pathology were used for the study. Echocardiography was recorded in B-mode in three positions: long axis, 4-chamber, and 2-chamber. Echocardiography frames that reflect the systole and diastole of the heart (308 samples in total) were taken as objects for classification. To obtain informative features of the selected objects, the genetic GMDH approach was applied to identify the best structure of harmonic textural features. We compared the efficiency of the following classification algorithms: logistic regression method, GMDH classifier, random forest method, and AdaBoost method.</p> <p><strong>Results</strong><strong>.</strong> Four classification models were constructed for each of the three B-mode echocardiography positions. For this purpose, the data samples were divided into 3: training sample (60%), validation sample (20%), and test sample (20%). Objective evaluation of the models on the test sample showed that the best classification method was random forest (90.3% accuracy on the 4-chamber echocardiography position, 74.2% on the 2-chamber, and 77.4% on the long axis). This was also confirmed by ROC analysis, wherein in all cases, the random forest was the most effective in classifying cardiac conditions.</p> <p><strong>Conclusions.</strong> The best classification algorithm for cardiac diagnostics by speckle-tracking echocardiography was determined. It turned out to be a random forest, which can be explained by the ensemble approach of begging, which is inherent in this classification method. It will be the mainstay of further research, which is planned to be performed to develop a full-fledged decision support system for cardiac diagnostics.</p> 2021-09-10T00:00:00+00:00 Copyright (c) 2021 The Author(s)
