Authors: Sander Mathilde D. , Madsen Rikke L. , Laursen Sisse H. , Hangaard Stine
Published: October 2023

Background: Artificial intelligence (AI) can potentially increase the quality of telemonitoring in chronic obstructive pulmonary disease (COPD). However, the output from AI is often difficult for clinicians to understand due to the complexity. This challenge may be accommodated by visualizing the AI results, however it hasn’t been studied how this could be done specifically, i.e., considering which visual elements to include. Aim: To investigate how complex results from a predictive algorithm for patients with COPD can be translated into easily understandable data for the clinicians. Methods: Semi-structured interviews were conducted to explore clinicians’ needs when visualizing the results of a predictive algorithm. This formed a basis for creating a prototype of an updated user interface. The user interface was evaluated using usability tests through the “Think aloud” method. Results: The clinicians pointed out the need for visualization of exacerbation alerts and the development in patients’ data. Furthermore, they wanted the system to provide more information about what caused exacerbation alerts. Elements such as color and icons were described as particularly useful. The usability of the prototype was primarily assessed as easily understandable and advantageous in connection to the functions of the predictive algorithm. Conclusion: Predictive algorithm use in telemonitoring of COPD can be optimized by clearly visualizing the algorithm’s alerts, clarifying the reasons for algorithm output, and by providing a clear overview of the development in the patient’s data. This can contribute to clarity when the clinicians should act and why they should act on alerts from predictive algorithms.

Authors: Mahmut Emilian Erman , Nicola Stelian , Stoicu-Tivadar Vasile
Published: October 2023

This paper describes the latest development in the classification stage of our Speech Sound Disorder (SSD) Screening algorithm and presents the results achieved by using two classifier models: the Classification and Regression Tree (CART)-based model versus the Single Decision Hyperplane-based Linear Support Vector Machine (SVM) model. For every single speech sound in medial position, 10 features extracted from the audio samples along with an 11th feature representing the validation of the (mis)pronunciation by the Speech Language Pathologist (SLP) were fed into the 2 classifiers to compare and discuss their performance. The accuracy achieved by the two classifiers on a data test size of 30% of the analyzed samples was 98.2% for the Linear SVM classifier, and 100% for the Decision Tree classifier, which are optimal results that encourage our quest for a sound rationale.
Clinical Acronym Disambiguation via ChatGPT and BING
Authors: Kugic Amila , Kreuzthaler Markus , Schulz Stefan
Published: October 2023

Clinical texts are written with acronyms, abbreviations and medical jargon expressions to save time. This hinders full comprehension not just for medical experts but also laypeople. This paper attempts to disambiguate acronyms with their given context by comparing a web mining approach via the search engine BING and a conversational agent approach using ChatGPT with the aim to see, if these methods can supply a viable resolution for the input acronym. Both approaches are automated via application programming interfaces. Possible term candidates are extracted using natural language processing-oriented functionality. The conversational agent approach surpasses the baseline for web mining without plausibility thresholds in precision, recall and F1-measure, while scoring similarly only in precision for high threshold values.
A Custom Image Recognition Model in the Cloud for Skin Diseases Identification
Authors: Dan Mircea-Aurelian , Nicola Stelian , Stoicu-Tivadar Lacramioara
Published: October 2023

In the context of global warming and increasing exposure to UV radiation, skin diseases are becoming more prevalent. Some of the most widespread skin conditions are solar lentigo and actinic keratosis. In this paper, we propose a technical approach related to the use of Azure Custom Vision services to classify these two conditions. The main advantage of using this service is the computational power offered by Azure. Additionally, generating a convolutional neural network model does not require a large dataset to achieve a good performance. For training the model, we used a dataset of 600 images from the ISIC database. The limitations of these approaches are imposed by the manual image labeling part that needs to be performed. As a result, we provide a trained model on a series of images that can be used for classifying images related to these two conditions. The performance of our neural network on the pre-trained images is 94%.

Authors: Jallal Manar , Serhier Zineb , Berrami Hind , Bennani Othmani Mohammed
Published: October 2023

The Moroccan healthcare system is facing several challenges in ensuring equitable access to quality services and reducing or at least controlling their rising cost. Telemedicine can address these two needs by optimizing the use of existing human and material resources through telecommunications. Today, the gradual increase in the population’s healthcare needs poses a major challenge to the Moroccan healthcare system, given the shortage of personnel in healthcare facilities and the persistent difficulties in accessing certain regions. In this regard, Morocco has established a regulatory framework defining the rules for the practice of telemedicine. Several initiatives have been launched, particularly in the public sector, aiming to cover 80% of medical deserts in Morocco by 2025.
Modeling the Application of IHE QRPH Profiles in Data Integration Centers: A Practical Approach with 3LGM2
Authors: Draeger Christian , Stäubert Sebastian , Kuntz Alessandra , Henke Christian , Winter Alfred , Sax Ulrich , Löbe Matthias
Published: October 2023

The Data Integration Centers (DICs), all part of the German Medical Informatics Initiative (MII), prepare routine care data captured in university hospitals to enable its reuse in clinical research. Tackling this challenging task requires them to maintain multiple data stores, implement the necessary transformation processes, and provide the required terminology services, all while also addressing the use case specific needs researchers might have. An MII wide application of the standardized profiles defined in the IHE QRPH domain might therefore be able to drastically reduce the overhead at any one DIC. The MII DIC reference model built in 3LGM2, a method to describe complex information system architectures, serves as a starting point to evaluate whether such an application is possible. We first extend the IHE modeling capabilities of 3LGM2 to also support the five profiles from the QRPH domain that our experts evaluated as relevant in the MII DIC context. We then expand the DIC reference model by some IHE QRPH actors and transactions, showing that their application could be beneficial in the MII DIC context, provided they surpass their trial status.

Authors: Kuusisto Hanna , Keränen Tapani , Saranto Kaija
Published: October 2023

A ‘Do Not Attempt Resuscitation’ (DNAR) order is one of the most important yet difficult medical decisions. Despite the recent European guidelines, health care professionals (HCPs) in general perceive challenges in making a DNAR order. We aimed to evaluate the types of problems related to DNAR order making. A link to a web-based multiple-choice questionnaire including open-ended questions was sent by e-mail to all physicians and nurses working in the Tampere University Hospital special responsibility area covering a catchment area of 900,000 Finns. The questionnaire covered issues on DNAR order making, its meaning and documentation. Here we report the analysis of the open-ended questions, examined based on the Ottawa Decision Support Framework with expanded individual decisional needs categories. Qualitative data describing respondents’ opinions (N=648) regarding problems related to DNAR order decision making were analysed using Atlas.ti 23.12 software. In total, 599 statements (phrases) dealing with inadequate advice, information, emotional support, and instrumental help were identified. Our results show that HCPs experience lack of support in DNAR decision making on multiple levels. Digital decision-making support integrated into electronic patient records (EPR) to assure timely and clearly visible DNAR orders could be beneficial.

Published: October 2023

Acute rhinosinusitis (ARS) is common in children and most often occurs in upper respirato-ry tract infections. Meanwhile, a disease duration of more than 7–10 days suggests a bacterial infec-tion and requires a change in the treatment approach to sinusitis. Any local condition preventing normal sinus drainage (i.e., inflammation) predisposes the patient to infection. ARS diagnosis is difficult because of the overlap between its clinical manifestations and symptoms of other common diseases, strong dependence on the subjective perception of symptoms by parents, and difficulties in physical examination of the child. The disease history, nature of symptoms, and duration are the basis for establishing a clinical diagnosis. In most patients, ARS resolves spontaneously, and in an uncomplicated course, antibiotics are not indicated. Intranasal steroids, irrigations, decongestants, and mucolytics are used as adjuvant therapy. However, data supporting the efficacy of these adju-vant therapies in children are scarce, and no strong formal recommendations on their use are avail-able. This paper discusses the key issues of ARS diagnosis and management in pediatric practice. KEYWORDS: acute rhinosinusitis, ARS, children, diagnosis, treatment, decongestants, acetyl-cysteine, tuaminoheptane sulfate. FOR CITATION: Kolosova N.G., Shatalina S.I. Management approach to acute rhinosinusitis: a pediatrician's perspective. Russian Medical Inquiry. 2023;7(8):537–542 (in Russ.). DOI: 10.32364/2587-6821-2023-7-8-11.
Protective effect of the extract from Aronia melanocarpa L. berries against cadmium-induced oxidative stress in the kidney: A study in an in vivo experimental model
Authors: Brzóska Małgorzata Michalina , Smereczański Nazar Michał , Rogalska Joanna
Published: October 2023

The destructive impact of cadmium (Cd) on the oxidative/antioxidative status of the kidney, as well as the possible beneficial effect of co-administration of a 0.1% aqueous extract from Aronia melanocarpa L. berries (AM), were studied in a rat model of low-level and moderate general population exposure to this heavy metal (1 and 5 mg Cd/kg feed, respectively, for up to 24 months). Total antioxidative status (TAS) of the kidney and the main indices of the enzymatic (superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase) and non-enzymatic (reduced glutathione and thioredoxin) antioxidative barrier were assessed. The total oxidative status (TOS) and concentrations of hydrogen peroxide, xanthine oxidase, myeloperoxidase, and oxidized glutathione were measured as markers of oxidative status. The oxidative stress index (OSI) was calculated (TOS/TAS) to estimate the intensity of oxidative stress in the kidney. The exposure to Cd, dose- and duration-dependently, weakened the enzymatic and non-enzymatic antioxidative potential of the kidney leading to a decrease in its TAS, as well as enhanced oxidative status of this organ resulting in the development of oxidative stress. The administration of AM during the low-level and moderate intoxication with Cd significantly protected from this xenobiotic-induced disruption of the oxidative/antioxidative balance and development of oxidative stress in the kidney. In summary, even low-level long-term exposure to Cd may result in the occurrence of oxidative stress in the kidney, whereas supplementation with chokeberry products may improve the oxidative/antioxidative balance preventing oxidative stress in this organ.

WHO has identified the increase in myopia as the world's greatest threat to vision health due to its association with vision-threatening complications like myopic macular degeneration, retinal detachment, cataract and open angle glaucoma. Pharmacological treatment with atropine is assessed as one of the best option in op-tical approaches to the control and inhibit of myopia progression. The aim of this study was to develop analytical method for quality control of 0.1 mg/mL atropine ophthalmic solution. UPLC analytical method for simultaneous determination of atropine sulfate monohydrate and its related substances described in Eur. Ph. and for additional impurities was developed. For method development low-dose of atropine formulations with a wide range of pH 4.5-6.6 were tested and the impact of formulation pH on the impurity profile was noted. The ionized form of tropic acid was observed in our studies in all buffered formulations with pH above 5. Additionally two isomers of atropine N-oxide were observed in the tested preparation with pH 6.6 in the presence of an oxidizing agent and were just possible to integrate with our new developed UPLC method. The ionized form of tropic acid was already defined in Berton et al. publication (1) and observed in the buffered formulation with pH 6.0. Our result complement and extend the impurity profile of atropine in wider pH range of atropine ophthalmic solutions.

Authors: Pająk Marek , Kamysz Elżbieta , Fichna Jakub , Woźniczka Magdalena
Published: October 2023

The present work describes the protolytic properties of the sialorphin derivative (Pal-Lys-
Lys-Gln-His-Asn-Pro-Arg) in an aqueous solution, at constant temperature 25.0 ± 0.1 °C and ionic
strength 0.1 M (NaClO4), over the entire pH range. The overall protonation constants of the studied
ligand were calculated by the potentiometric method. The logarithm values of the stepwise
dissociation constants of the sialorphin derivative were found to be: [LH] = 11.88 ± 0.09, [LH2]+ = 9.96 ±
0.03, [LH3]2+ = 8.71 ± 0.03, [LH4]3+ = 5.49 ± 0.03, [LH5]4+ = 2.82 ± 0.03. The percentage of each species
formed in an aqueous solution was estimated from the species distribution curves as a function of pH
(82% [LH] at pH 11.0, 68% [LH2]+ at pH 9.3, 95% [LH3]2+ at pH 7.1, 90% [LH4]3+ at pH 4.2, 85% [LH5]4+
at pH  2.0). The five protonation constants indicate that the studied ligand can be very active in
forming complexes with different metal ions. In addition, the sialorphin derivative can also be tested
as a bioactive material, which warrants its further in vitro and in vivo studies.

Sore throat is a common symptom that accompanies infectious and non-infectious diseases. World standards of sore throat treatment mainly regulate approaches to the diagnosis of the streptococcal nature of sore throat and the use of antibacterial therapy in a positive case. However, the predominant cause of sore throat is viruses and symptomatic treatment can be used. The study presents a brief overview of modern medical standards for sore throat, defining the role of a pharmacist and the experience of certain countries in involving him in the diagnosing and treating process. An analysis of the content of the Ukrainian Pharmacist’s protocol “Symptomatic treatment of sore throat” and the dynamics of its changes was carried out. Pharmacist’s Protocol elaborated in Ukraine successfully combines the algorithm of the primary pre-medical assessment of the patient’s condition with information and advisory support when dispensing over-the-counter medicines for responsible self-treatment of sore throat. However, certain improvements in the list of recommended medicines may be appropriate.

Background and objective After a large-scale natural disaster, the lack of supply and unfair distribution of relief items can cause high human casualties and hinder the function of the humanitarian supply chain. Therefore, this study aims to present a framework based on mathematical modeling for the proper distribution of relief items among the affected areas in Tehran. Method In this study, mathematical modeling was used for the distribution of relief items in a humanitarian supply chain at two high and low levels. For this purpose, a multi-purpose and multi-level humanitarian supply chain was first developed. The proposed model had three objective functions that were solved by the weighted sum method. Results According to the results, with the decrease in the supply parameter, the amount of unmet demand increased, and there was a shortage of essential items in all periods. This shortage affected the desirability of distribution among recipients and had a negative effect on the performance of the humanitarian supply chain and fair distribution. On the other hand, with the increase in supply parameter, there was a surplus of items, and considering the time window, there may be no demand for some food items, which can lead to their spoilage. In this case, an additional cost is imposed on the chain. Conclusion The proposed model is suitable in the event of natural disasters locally in urban areas of Tehran (with a certain number of residents). The results of this study can be useful for managers to make appropriate decisions after disasters and control the situation.

Authors:   Moscow Aviation Institute (National Research University), Simankov D. S.
Published: October 2023

A high-precision ohmmeter that delivers rectangular pulses to the connected thermal sensors of various designs was developed. During the heating pulse, the electrical resistance of the sensor(s) is measured at a given frequency. The thermophysical properties of the objects under study are calculated according to conventional models. The device is capable of implementing both absolute and relative measurements, which are carried out in one pulse. The uncertainty of the measured current-voltage characteristics of the measurement channel was estimated. Experiments were conducted on human skin using small-size Pt100 platinum resistance thermometers on a substrate. The use of modern sensors on a coated substrate extends the application range of the developed device in terms of non-destructive analysis of such thermophysical properties, as thermal conductivity, thermal activity, thermal diffusivity, boiling and melting temperatures of conductive and magnetically conductive measurement objects. The compact size of the sensor permits investigations on small volumes. The range of measured temperatures and pressures is determined by the sensor. The device compactness enables its use for both industrial purposes in laminar flow environments and educational purposes. The device can be used to study the thermophysical properties of plastic amorphous and bulk materials, biological and plant objects, liquids and gases and their mixtures, solids, inhomogeneous bodies in structure with and without a melting component. The irregular thermal regime allows fast and/or irreversible processes with a thermal field to be studied.

The synthesis and comparative analysis is conducted for the following control systems for a two-mass object: slave control with external feedback on the speed of the first mass; multiloop slave regulation; modal control; subordinate regulation using a correction factor and a neurocontroller with a reference model. The resulting graphs of transient processes in terms of moment and speed of the driven pulley of the considered twomass system with an elastic replacement belt are presented and analyzed. The simulation results have shown that control systems with a modal controller and a neurocontroller show good results in the problem of damping elastic vibrations of a two-mass system in comparison with other considered control systems.

This paper studies the process of modeling an electrical contact connection as an element of a common system – an electrical circuit – based on the study results on the parameters characterizing the state and quality of the electrical contact connection. The Simulink graphical programming software based on MatLab (The MathWorks, Inc.) is used to model and simulate the processes occurring in the system. This article aims to confirm theoretical calculations on the effect of the state of an electrical contact connection on the quality and efficiency parameters of the entire electrical system. The results obtained will help, first, to evaluate the contribution of the processes under study to the overall change in the state of the system; secondly, to justify the necessary accuracy of equipment for the implementation of a laboratory stand in order to practically confirm the results.

An approximation method for calculating thermal energy, based on the use of neuro-fuzzy calculations is considered. Method for applying approaches based on the concepts of artificial intelligence to improve the accuracy of energy calculations based on periodically obtained data on metering parameters is described. An assessment is made of the accuracy of the operation of a neuro-fuzzy system when approximating equations that describe the physical dependence on several parameters of the environment. The reasons that limit the use of neuro-fuzzy systems in approximation problems are analysed.

In this work, we aim to develop a methodology for solving kinematic problems for a robot with a serial connection of links of various movement types. The research methodology included the methods of trigonometric transformations, algorithmization, and programming. As a result, a program for solving direct and inverse problems, and a kinematic diagram of the robot and its working area was developed. The program can be used to optimize the process of developing automated lines based on robots in the field of organizing space or selecting the design of a manipulator. The presented algorithms can be applied in control systems to transform coordinates, thereby shifting from positioning by specifying displacements to positioning by Cartesian coordinates.

Authors:   Saint Petersburg Electrotechnical University, Kosyanov N. M.
Published: October 2023

A theoretical substantiation for a new method for determining the state of electrical contact connections as part of an electrical complex is proposed. The influence of possible operating factors leading to a decrease in the quality and reliability of such connections is considered. The proposed method takes into account all known diagnostic features and the relationship between them. The data obtained create a regulatory framework for assessing the state of electrical contact connections based on the results of diagnostics, as well as for determining the technical parameters when designing new connections.

A timely blood test is essential to detect possible abnormalities in the body. Blood somewhat objectively reflects the state of the internal environment in which all metabolic processes take place. The blood test is one of the most informative laboratory diagnostic tools, which provides essential information about the functional state of various organs and systems of the body. The work aimed to investigate the changes in morphological parameters, protein profile, and activity of aminotransaminases in the blood of turkeys in the presence of keel “namins”. The research was carried out at “Indykat” Ltd. in the village Kadubivtsi of the Lviv region on turkeys of the Big-6 breed on two groups of turkeys, 10 birds each. The turkeys of the control group were clinically healthy, and those of the experimental group had visible clinical signs of “namin” on the keel. The results of the research showed that the number of erythrocytes in the blood of clinically healthy birds was 2.5 ± 0.19 T/l, leukocytes – 21.8 ± 1.36 G/l, hemoglobin content – 90.5 ± 2.54 g/l, and the hematocrit was equal to 29.4 ± 1.44 %. In the presence of “namins” in the blood of turkeys, the number of leukocytes and hematocrit, compared to the control, was higher by 15.2 and 3.8 %, respectively, and the number of erythrocytes and hemoglobin content was lower by 16.1 and 11.3 %. Analyzing the leukogram of the blood of the turkeys of the research group, the appearance of basophilic leukocytes and young neutrophils was established, the number of which was 1.1 ± 0.08 and 0.2 ± 0.01 %, respectively. Compared to the control, the number of rod-shaped and segmented neutrophils was higher by 1.3 and 6.3 %, monocytes by 16.3 %, and eosinophils and lymphocytes were lower by 1.3 and 16.8 % and amounted to 6, 3 ± 0.27 and 41.1 ± 2.41 %. The level of total protein in the blood of birds in the pectoral muscles that developed and formed “namins” was 26.4 ± 1.35 g/l and was 6.7 % lower than that of the experimental group. In the presence of “namins” on the keels of turkeys, a 4.4 % higher level of globulins, which perform a protective function, and a 17.1 % lower amount of albumins were found. The pathological process that developed in the pectoral muscles of turkeys led to an increase in the activities of alanine aminotransferase and aspartate aminotransferase in the blood of turkeys to 32.4 ± 1.23 and 314.2 ± 14.2 units/l, which was more significant than indicators of the control group by 8.6 and 8.3 %, respectively.
Clinical and hematological сhanges in viral panleukopenia in cats
Authors: Kolomak I.
Published: October 2023

Cat infectious diseases have become widespread due to the increase in the number of stray cats; feline viral panleukopenia is no exception. It is caused by a single-stranded DNA virus of feline parvovirus, characterized by high contagiousness, fever, damage to the gastrointestinal tract, respiratory organs, heart, general intoxication, and body dehydration. The research aimed to study the hematological indices of blood and biochemical indices of plasma in viral panleukopenia of cats. During the development of intestinal panleukopenia syndrome in animals, vomiting and diarrhea were noted. The development of inflammatory processes in the digestive organs causes pain in the abdominal cavity, due to which a specific “sitting posture” occurs. An acute course was most frequently noted, characterized by a sudden increase in temperature to 42 °C, vomiting, diarrhea, and cachexia. Studies of hematological indices of blood indicate the development of thrombocytosis, neutrophilia, monocytosis, and lymphocytosis, which corresponds to the acute course of the disease with a focal inflammatory process. Erythropenia leads to systemic disorders of the cardiovascular system, which provoke the weakening of the body, accompanied by cachexia. Studies of biochemical parameters of plasma indicate systemic disorders of organs developing in the body. Thus, an increase in total protein indices and globulin fractions indicates inflammatory processes in the body, particularly the digestive and urinary organs. In addition, one of the renal impairment indices was an increase in creatinine and urea, and an increase in glucose, total bilirubin, AST, and α-amylase indicates liver and pancreas dysfunction. In some cases, hepatitis and infectious toxicosis may develop. The study of hematological indices of blood and biochemical indices of plasma will ensure a complex picture of morphological changes that develop in the body of cats with panleukopenia. The obtained data will permit the monitoring of an animal's condition with the applied therapeutic scheme and the form of a prognosis.
