Metoda kowariancji wirów jako nowoczesne narzędzie w badaniach wymiany CO2 między ekosystemami leśnymi, podmokłymi i rolniczymi a atmosferą
Authors: Urbaniak Marek
Published: April 2024

Aim of study. In the last decades the mean global temperature on the Earth’s surface has increased extremely rapidly. This increase was mostly caused by the anthropogenic emission of greenhouse gases, mainly carbon dioxide, which intensified the greenhouse effect and climate changes. Climate changes also affect ecosystems, which are reservoirs of carbon and links in its cycle, by a complex system of feedbacks between different elements of the environment. Depending on the scenario of CO2 emission in the development of the world, the future climatic conditions will influence the role of ecosystems in the carbon cycle and thus their condition. The current potential of forest, wetland and agricultural ecosystems to sequester carbon were assessed on the basis of selected areas. The author also tried to determine the influence of rainfall and humidity on variations in the productivity of the ecosystems at different time scales. Material and methods. The CO2 exchange between the Scots pine forest in Tuczno, the peatland in Rzecin and the farmland in Brody was assessed by making measurements with the eddy covariance (EC) method. The EddyPro® software was used to calculate fluxes. First, the data from all the sites were checked for quality. Next, the missing data were filled with two methods: Max Planck Institute of Biogeochemistry (MPI) and Fluxnet Canada Research Network (FCRN). Both methods gave comparable results. Two systems equipped with open-path (OP) and closed-path (CP) gas analysers were used for EC measurements above the forest. The measurements made with the OP system indicated greater assimilation of CO2 than the measurements made with the CP system. The research showed that the measurements made with the OP system needed additional correction and the correction methodology was proposed. After the correction there were similar monthly totals of the net CO2 exchange fluxes obtained from both systems. This finding is important in the context of comparisons of EC measurements made in different parts of the world, in various ecosystems. Results and conclusions. In the current climate the average carbon sequestration potential of the Tuczno forest amounted to 418.5 ±11.8 g·m–2·year–1, whereas in the Rzecin peatland it was 118.6 ±26.0 g·m–2·year–1. Forest and wetland (peatland) ecosystems may play an important role in the removal of anthropogenic CO2 emissions from the atmosphere. In comparison with the assimilation of CO2 the emission of this gas at the forest and agricultural sites increased during rainfall. This effect was mainly caused by reduced total radiation density (Rg) at that time. The increase in CO2 emission, caused by intensified respiration of the ecosystem, was observed only in the farmland.
Nonparametric procedure for comparing the performance of divisions of a network organization
Authors: Koldanov Petr , Koldanov Vladimir
Published: April 2024

To solve the problem of comparative efficiency analysis of branch operations for a small volume of randomly observed data, a non-parametric approach is relevant, since it does not require a probabilistic model of observations. Comparing the results of the non-parametric approach with the results obtained within the traditionally used Gaussian model is also relevant. Additionally, obtaining a consistent comparison of a group (of no less than three) branches is important. Currently, the non-parametric approach and the corresponding comparison with the known results of solving the problem considered in this work obtained within the framework of the normal model are absent. In addition, insufficient attention is paid to the search for methods of obtaining consistent solutions. This work to some extent fills these gaps. This work uses non-parametric statistical methods and theory of simultaneous hypothesis testing to address these problems. This paper proposes a procedure for comparative analysis of the efficiency of several units within a network organization with a small volume of observations based on the Mann–Whitney tests. We carry out a comparison of the results obtained from the proposed non-parametric procedure with results based on extensions of Student’s t-tests. We propose a method for reducing the number of compatibility problems based on the search for an appropriate significance level. We provide an example of a fully consistent comparison of the efficiency of branch operations.
Development of an intelligent assistant for selection of goods in the process of dialogue with the user
Authors: Palchunov Dmitry , Yakobson Alexander
Published: April 2024

This article is devoted to the development of methods for creating intelligent assistants. Intelligent assistants can be used in call centers to solve customer problems, to solve technical support tasks, to help people with disabilities, to help in choosing goods, etc. We consider intelligent assistants that engage in argumentative dialogue with users, aimed at finding goods and services that maximally satisfy users’ wants and needs. The development of the intelligent assistant is based on a four-level model of the subject domain and a semantic model of the user. The system under development automates the process of search and decision justification through the reuse of domain cases: accumulated knowledge about previous dialogues with users. This gives the system we developed an advantage over existing analogues, which are incapable of reusing knowledge about previous dialogues. The paper develops a case-based approach to building an intelligent system capable of reasoning about its responses. For this purpose, an argumentation graph is constructed, methods for structuring domain cases are developed, and ontological homomorphisms are used to transform the available domain cases into a finished solution. A description of model-theoretical methods for constructing intelligent assistants is presented. The cases of goods, users and dialogues of an intelligent assistant with users are formally described in the form of partial models. The transformation of domain cases and similarity of cases are formalized using ontological homomorphisms of partial models. The purpose of the developed dialogue system is not only to select a solution according to the user’s request, but also to find out the tasks that the user is going to solve, to analyze his argumentation, and then to justify the proposed solution to the user, to show that this particular product or service will be able to meet his needs.
Diagnostic paradoxes of sepsis
Authors: Igor Klepikov
Published: April 2024

Sepsis is currently one of the most important problems of medicine, and the treatment of this category of patients presents great difficulties and is characterized by high mortality. Acute Pneumonia (AP) has been the leading cause of septic conditions for many years, the proportion of which has recently begun to exceed half of all cases. The modern concept of AP considers the causative agent of the disease as the main cause of its occurrence and development, but for many years the search for reliable differential diagnostic criteria depending on the etiology has not been found. The peculiarities of the localization of AP, unlike other inflammatory diseases, force us to pay attention to the fundamental differences in the parameters of blood flow in the two circulatory circles. The inevitability of the onset of the inflammatory process with a vascular reaction forces us to understand the mechanisms of AP development on the basis of already studied, confirmed, and classical materials of medical science. New ideas about the pathogenesis of the disease make it possible to understand its leading importance in the observed pattern of AP and to recognize the obvious over diagnosis of sepsis in this category of patients. Understanding the need for such a step can significantly reduce the number of patients with sepsis, and a pathogenetic approach to medical care will really improve treatment outcomes.

V.S. Solov’ev’s pseudo-Ḥāfeẓ and the influence of the translation tradition of G.F. Daumer and A.A. Fet
Authors:   Università degli Studi di Perugia, Corritore A.L.
Published: April 2024

The essay analyses the Russian translations of Ḥāfeẓ by V.S. Solov’ev in 1885 (24 poems in the first journal edition, reduced to 11 in all subsequent volume editions). The Russian philosopher’s interest in the Persian poet is part of European, and specifically German, Orientalism, which became popular since the publication of J.W. Goethe’s “West-Eastern Divan” (1819). This interest has a direct connection with the translations of Hafiz published by A.A. Fet in 1860. As has been shown, Fet translated Ḥāfeẓ not directly, but through the poetic imitations of him by the German poet G.F. Daumer (“Hafis. Eine Sammlung persischer Gedichte”, 1846; in particular, he used the second edition of these poems, published in 1856). Solov’ev’s lyrics have hitherto been thought to be translations of Hafezian imitations by the German poet F. Bodenstädt (1877). The essay shows how actually Solov’ev used the same imitations by Daumer as Fet, probably taking them from the same volume used by the older poet. This enables to relate the two Hafezian poetic cycles more directly and to draw some general considerations on the different intentions that drove the two poets in translating the Persian mystic: for both, Ḥāfeẓ was functional in conveying their own artistic form and philosophical meaning, although each of them had a different understanding of him. The analysis shows that Solov’ev was much closer to Ḥāfeẓ than Fet. In the Persian poet Fet saw a singer of beauty and regarded the aesthetic phenomenon as self-valuable; for Solov’ev, beauty was a conduit of the divine, as it was for Ḥāfeẓ. In his poems, the young beautiful cupbearers (replaced in Daumer by the beloved woman) are always the personification of God. It was these themes (the power of love; its dual nature, both mystical and earthly; the immanence of the divine in the world) that Solov’ev would develop in the following years and would be reflected in a series of articles key to understanding his worldview and which became the object of attention of Symbolist poets: “Beauty in Nature” (1889), “The General Meaning of Art” (1890), “The Meaning of Love” (1892), “The Life Drama of Plato” (1898), and others.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Denysenko V.V.
Published: April 2024

The article is devoted to the study of problematic issues related to the types of criminal procedural relations at the pre-trial investigation stage between an investigator and other parties to criminal proceedings. The purpose of the article is to classify the types of criminal procedural relations at the pre-trial investigation stage between an investigator and other parties to criminal proceedings. Based on a systematic and comparative analysis of the legal provisions of the current CPC of Ukraine and the by-laws regulating pre-trial investigation, the author proves that at the pre-trial investigation stage, there is a variety of criminal procedural relations between its subjects. The nature of these legal relations is different. Some of these legal relations have only their own peculiarities and specific features, which are determined by the legal status of their subjects, procedural functions performed by certain subjects in criminal proceedings, their procedural interests, stages of pre-trial investigation, etc. This diversity of criminal procedural legal relations at the pre-trial investigation stage allows classifying these relations according to certain criteria with a view to improving the criminal procedural status of their subjects, and to enhance the efficiency of pre-trial investigation and strengthening criminal procedural guarantees of participants to criminal proceedings in achieving the goals and fulfilling the tasks of criminal proceedings. The author substantiates that based on the results of the analysis of doctrinal approaches to the classification of criminal procedural relations at the pre-trial investigation stage according to such criteria as: the task of criminal proceedings, procedural interest of criminal proceedings subjects, procedural functions of criminal proceedings subjects; sources of regulation of criminal procedural relations, content of criminal procedural relations, the most productive for studying the problems of procedural status of investigators and enhancing. The author offers her own classification of criminal procedural relations at the pre-trial investigation between the investigator and other subjects of criminal proceedings.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Kolomiiets K.V.
Published: April 2024

The article is devoted to the relationship between the subject and the limits of evidence in criminal proceedings, establishing their relationship. The correct definition of these concepts in practice contributes to the fulfillment of the tasks of criminal proceedings, in particular, by establishing all the circumstances that are subject to proof in criminal proceedings. The subject of proof and the limits of proof have been creating a debate among scientists and practitioners for a long time due to their uncertainty, as they are of essential importance for the process of proof in criminal proceedings, and accordingly, the relevance of this topic is obvious. The author of the article aims to solve the problem related to the perception of the subject of proof and the limits of proof as equivalent concepts, to establish the relationship between the subject and the limits of proof in criminal proceedings, to propose possible ways of solving other urgent problems related to the topic of the article. The author considered scientific approaches to understanding the subject of proof and the limits of proof, as well as their practical significance. Problematic issues of the relationship between the subject matter and the limits of evidence in criminal proceedings have been identified. Based on the analysis of the literature and the provisions of the current Criminal Procedure Code of Ukraine, the essential features of these concepts were determined, which further contributed to their delineation. It is proposed to understand the subject and the limits of proof as interrelated categories, but not equivalent.
INTERACTIVE STRATEGIES FOR DEVELOPING THE READINESS OF FUTURE TEACHERS OF HIGHER EDUCATION FOR PROFESSIONAL ACTIVITIES
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, PLAKHOTNIK Olga
Published: April 2024

The article talks about the fast spread of interactive, discussion and role-playing forms of collective learning in combination with student research projects and the use of electronic means and technologies. The interactive strategy has the following characteristics: a) training is based on the interaction of the subjects of training, the environment which is the space for the application of acquired experience; b) the educational process changes the interaction of learning subjects, so the activity of the teacher is inferior to the activity of the student where the main task of the teacher is to create conditions for increasing the student's initiative, understanding, reflection, application in practice. A teacher who aims to use interactive technologies in pedagogical activity must develop methodical support for pedagogical activity. It is necessary to have regulatory and organizational support for providing educational process, in particular, it is necessary to have educational and methodological documentation that regulates the teacher's activity: working curriculum, educational program, working program of the educational discipline, etc.; secondly, instructional and methodical support – that is explanatory and instructional documentation which ensures the effective inclusion of education seekers in the educational process with teaching support at all stages of its implementation (instructions and methodical recommendations (forum, chat, classroom, etc.), methodical materials for students on the implementation of various types of educational activities (testing, writing essays, project activities, etc.); thirdly, educational resource support is printed, electronic and software resources that are intended for use directly during education (printed and electronic manuals, materials of lectures, presentations, test programs, etc.). The most effective way of reproducing the acquired competences remains the practical realization of the potential of education seekers during the period of assistant practice: individual or group consultation, conversation-training, "educational event", coaching, webinar, assistant internship, etc.
Evaluation of the strengthening components in 0.4%С–1.3%Mn–0.1%V steel after quenching and high temperature tempering
Authors:   Ural Federal University, Kuzmina А. V. , Khotinov V. A. ,   Ural Federal University
Published: April 2024

Transmission electron microscopy (TEM), electron backscatter diffraction (EBSD), and X-ray diffraction analysis are used to monitor the evolution of the microstructure of a microalloyed medium-carbon steel and to evaluate quantitatively the strengthening components and their relative contribution to the yield strength of this steel quenched and tempered at 650 °C. As the duration of isothermal tempering tem increases from 2 to 3000 min, the steel softens in two stages: a sharp drop of the strength properties, ~100 MPa/min, at stage I (tem ≤ 8 min) is followed by weak softening, ~0.1 MPa/min at stage II (tem ≥ 64 min). It is shown that the main contribution (q ~ 80%) to the yield strength of the steel is made by the combined effect of the dislocation and grain-boundary (due to the lath boundaries) strengthening mechanisms at the first stage of martensite tempering, and by subgrain strengthening at the second stage of tempering.

Bleeding is one of the most common causes of death in armed conflicts. Moreover, many medical devices have been developed to stop ongoing external bleeding, including local hemostatic agents, turnstiles, and compressors. Stopping ongoing internal bleeding remains an urgent problem in military medicine. Before the current era wherein qualified medical care is provided, internal bleeding is impossible to stop. Thus, new methods and techniques are being developed to stop (control) intracavitary bleeding at the prehospital stage. In this study, a chitosan-based agent was developed in the form of a gel to stop internal bleeding. In an experiment of large laboratory animals as models of ongoing intra-abdominal bleeding, the effectiveness of the developed drug was evaluated, and it demonstrated high hemostatic efficiency. The developed local hemostatic agent, administered by laparocentesis, could stop grade 3 bleeding according to the validated intraoperative bleeding scale from the liver wound without causing inflammatory changes in the surrounding organs and tissues. The local hemostatic agent helped avoid fatal outcomes in the experimental group compared with the control group (one fatal outcome in three animals). Changes in the hemoglobin level and erythrocyte count indicated that hemostasis occurred almost immediately after the administration of the local hemostatic agent in the experimental group, whereas in the control group, hemostasis remained unstable throughout the observation period. The histological examination of liver preparations confirmed stable hemostasis without the development of a local inflammatory reaction or necrosis when a local biocompatible hemostatic agent was used. The developed technology can be used starting from the stage of first aid, helping stop intracavitary bleeding at the prehospital stage and improving the treatment outcomes of wounded individuals and those with abdominal injuries.
Methods for assessing the quality of medical care in Russia and abroad: formation and modern aspects

Published: April 2024

The study presents the results of the analysis of available literary sources covering the historical and modern aspects of assessing the quality of medical care in the healthcare systems of the Russian Federation and some foreign countries and shows the relevance and feasibility of improving the methodology for assessing the quality of medical care in the Armed Forces of the Russian Federation. At present, many methods are used for assessing the quality of medical care in the healthcare system of the Russian Federation; however, none of them contains an exhaustive set of criteria that would allow assessing the quality of medical care provided in full. In the Armed Forces of the Russian Federation, the methods used to assess the quality of medical care are also not perfect, which leads to a decrease in the effectiveness of management decisions and thereby a decrease in the effectiveness of military medical organizations and units. To this end, active development of assessment indicators and criteria for the quality of medical care, introduction of new assessment methods, including the use of automated data accounting and analysis tools, and improvement of the procedures and standards of medical care are necessary. The most promising area is the use of comprehensive methods for assessing the effectiveness and quality of medical care, which have recently become widespread. Their application provides comprehensive control over compliance with medical care requirements and allows us to investigate the conditions wherein it is indicated, assess the degree of patient satisfaction, and helps optimize the assessment procedure. In addition, to improve the effectiveness, continuity in the implementation of control measures performed at various levels both within the medical organization and with the participation of departmental and state control bodies must be ensured. To do this, close interaction of all control bodies must be organized, and their activities must be integrated into a single quality management system for medical care. The results of the assessment of the quality of medical care can help determine the main directions of the development of the medical and diagnostic process and optimize the work of medical personnel, which increases the importance of work aimed at improving the assessment methodology. In addition, the quality control of medical care in the Armed Forces of the Russian Federation must be further improved.

The effectiveness of anticoagulant therapy in the prevention and treatment of pulmonary artery thrombosis and the possibility of anti-inflammatory therapy in preventing this complication in clinical practice and experiments were assessed. Data from patients with a new coronavirus infection and those suffering from urgent noninfectious pathology with confirmed pulmonary artery thrombosis were retrospectively analyzed. The outcomes of anticoagulant therapy and anticoagulant therapy combined with glucocorticoid and/or anticytokine drugs were assessed. Histological preparations of the lung vessels of patients were examined. Using an experimental model of rats with induced thrombosis of the posterior vena cava, changes in the pulmonary artery branches were assessed in the main group administered with edible mussel (Mytilus edulis) hydrolyzate and the control group given a physiological solution. No statistically significant relationship was found between the therapeutic, intermediate, and preventive anticoagulant therapy regimens and mortality, changes in lung dynamics, and D-dimer levels in 313 patients with new coronavirus infection. No predominance of any anticoagulant therapy regimen used was found among deceased patients. Thirty-nine patients were treated with glucocorticoid and/or anticytokine drugs in the presence of anticoagulant therapy. No statistically significant relationship in the onset of thrombotic complications was found between the groups receiving therapy with glucocorticoid and anticytokine drugs. No differences were noted in the drug-induced pathomorphosis of the wall of the pulmonary artery branches in the group receiving anticoagulant therapy or in the group receiving a combination of anticoagulant therapy and glucocorticoid and/or anticytokine drugs. Pulmonary artery thrombosis developed in all 19 patients suffering from urgent noninfectious pathology, 11 of whom were under anticoagulant therapy. In 12 of 15 rats in the control group with thrombosis of the posterior vena cava, blood clots were found in the lumen of the pulmonary artery branches. In 14 rats of the main group administered M. edulis hydrolyzate, no blood clots were found in the pulmonary artery branches. Thus, the systemic effects of anticoagulant therapy were offset by the local prothrombotic effects of the vascular wall caused by inflammation. Glucocorticoid and anticytokine drugs did not affect inflammatory changes in the vascular wall and did not prevent pulmonary artery thrombosis. The introduction of M. edulis in the experiment prevented pulmonary artery thrombosis in the presence of posterior vena cava thrombosis, which indicates a promising direction in the search for pathogenetic prevention of this complication.

Authors: Asencios-Trujillo Lucía , Obispo-Asencios Christian-Andrés
Published: April 2024

Introducción: La inmediatez es la emisión de adecuadas conductas no verbales de gestos y posturas, percibidos como conductas no verbales asertivas, las cuales permiten modular los circuitos emocionales en función de un sistema de valores, influyendo en la disposición, motivación, interés y cognición de los estudiantes para el aprendizaje. Objetivo: Analizar el nivel de inmediatez de los docentes en la interrelación con los estudiantes, durante la práctica pedagógica en tiempos de pospandemia. Metodología: Estudio con enfoque cuantitativo, investigación de tipo descriptiva y con diseño descriptivo analítico simple de corte transversal. La población fue de 312 docentes universitarios peruanos, seleccionando por muestreo no probabilístico a 150 sujetos. Se aplica el cuestionario-­inmediatez-NIS adaptado por Richmond, McCroskey y J­onhson en el año 2013, con buena validez de contenido, y alta confiabilidad (.808). Resultados: El 22% con nivel alto de inmediatez, manejan sus emociones, comportándose en función de su capacidad cognitiva, asumiendo actitudes abiertas y receptivas, demostrando prudencia y tolerancia, el 78% presentan bajos niveles de inmediatez, reaccionando por impulso, demostrando ser intransigentes e inflexibles. C­onclusiones: La habilidad social impactante en la interacción docente-estudiante es la conducta asertiva, emitida mediante los componentes no verbales, evidenciando un estilo de comportamiento, con cierto nivel de inmediatez. Los docentes con altos niveles de inmediatez tienden a tener autocontrol, emiten comportamientos no verbales apropiados, creando entornos favorables en la interacción pedagógica, así mismo, quienes presentan niveles bajos reflejan malestar emocional con mayor riesgo de mostrar conductas inadecuadas, evidenciando comportamientos no verbales agresivos y/o pasivos.

There is no denying the importance of prostate cancer as a leading cause of mortality and morbidity in men. As such, it represents an important driver of healthcare costs and there is a (mostly unmet) need to provide evidence that assists decision-makers in prioritizing one management strategy over another in budget planning. Theranostics in prostate cancer represents a non-invasive out-patient strategy for patient management, which consists of imaging with a PSMA-based agent, followed by targeted radionuclide therapy with either a beta emitter (such as Lutetium-177) or an alpha emitter (such as Actinium-225). Evidence for these management approaches is mounting with FDA approval of imaging and therapy agents following landmark trials like the ProPSMA study, the VISION- and the TheraP trial. Despite the explosion in publications on the use of targeted radionuclide therapies in prostate cancer, studies that compare the cost-effectiveness of available nuclear medicine imaging and treatment strategies remain hard to find. The aim of this mini review was to summarize the most important current evidence related to cost-effectiveness strategies that evaluate imaging and targeted radionuclide therapies for PSMA-based PET theranostics. We found a paucity of literature that deals with healthcare costs, with an obvious need for more cost-effectiveness studies to demonstrate the positive impact of nuclear medicine in the management of oncology (and other) patients. These studies need to be based on well-conducted clinical trials and meta-analyses, with appropriate model simulations and decision analysis and should ideally be reported according to the CHEERS 2022 guidelines to improve uniformity and robustness.

The presented case involves the evaluation, diagnosis, and management of a 20-year-old male high-level skier who presented with persistent right knee pain following a ski crash. The patient reported hitting his right knee against a tree during the accident, resulting in intermittent swelling and a sensation of a mass within the knee. Despite some initial improvement in the sensation, the pain then became persistent and worsened by activity. Physical examination revealed limited symptoms during gait and functional movements, as well as restricted medial joint line tenderness and a mildly positive McMurray's test on the right knee. Magnetic resonance imaging findings prompted an orthopedic referral, leading to a right knee arthroscopy. The procedure involved resection of nodular synovitis and a diffuse synovectomy, with pathology confirming pigmented villonodular synovitis (PVNS). Despite post-operative complications, including methicillin-resistant Staphylococcus aureus bacteremia, ultimately, the patient's recovery was successful with the gradual restoration of pain-free range of motion through physical therapy. Follow-up assessments and magnetic resonance imaging scans indicated sustained improvement and no signs of pigmented villonodular synovitis recurrence.

Background: Nonpharmacological approaches are recommended as first-line treatment for the neuropsychiatric symptoms of persons living with dementia. Tailored Activity Program is a non-pharmacological approach which has shown to reduce neuropsychiatric symptoms and functional dependence of persons living with dementia at the community, as well as caregiver’s distress. The aim of the study is to assess the feasibility of a project in which the Tailored Activity Program is delivered partially at an acute hospital ward and partially at the patient's home. Material and Methods: The study is aimed at enrolling 50 dyads (patients/caregivers) from the memory clinic, acute geriatric ward, or short-stay emergency department at the IRCCS San Gerardo dei Tintori, Monza (Italy). Inclusion criteria are: the patient’s clinical diagnosis of dementia, clinically detectable neuropsychiatric symptoms (Neuro Psychiatric Inventory, NPI score >6 in at least one item), the ability to participate in activities of daily living (Katz’s index ≥ 2), the presence of a caregiver (aged ≥ 21 years; minimum 4 hours of daily care), and the willingness of the dyad patient/caregiver to participate in the project. Treatment is delivered both i) in hospital (2 sessions) and ii) at home (6 sessions), including occupational therapy, telemedicine and nursing care provided once a week. The following variables are measured: Neuro Psychiatric Inventory, Time Up and Go Test, Katz’s Index and the level of caregiver’s sense of competence with the Sense of Competence Questionnaire. Data are collected both at baseline, at the end of the treatment, with a follow-up scheduled at 4 months after enrollment. Primary outcome measure is the dyad's retention rate at 4-month follow-up. Secondary outcomes are the reduction in the patient’s frequency and severity of NPS; the improvement in the patient’s Time Up and Go Test score; the improvement in the patient's levels of autonomy and participation in activities of daily living and improvement in the caregiver’s Sense of Competence Questionnaire score. Results and Conclusion: We seek to evaluate whether the Tailored Activity Program is well-received by the patient/caregiver dyad and, consequently, whether our project is feasible. If this objective is achieved, and if we also report some improvement in the secondary outcomes, we can then plan a larger multicenter study aimed at evaluating the effectiveness of this approach, partly delivered at the hospital and partly at patient’s home.

Aims: Our goal was to obtain comprehensive and accurate information about primary extranodal non-Hodgkin lymphomas of the head and neck region to contribute to the advancement of medical knowledge in this field. Materiels and methods: We conducted a retrospective study of 341 patients with primary extra-nodal, non-Hodgkin lymphomas of the head and neck, over a period of 7 years from January 2016 to December 2022, in the departments of ENT and Head and Neck Surgery and Hematology, with the help of the department of anatomical pathology of the university hospital Mohammed VI of Marrakech. Results: 341 patients, with primary extra-nodal, non-Hodgkin lymphomas of the head and neck, was included, with an average age of 57 years, and a sex ratio male/female of 2.21 . in more than half of the cases; Waldeyer's ring was concerned; especially palatine tonsils. Type B NHL was the most frequent and involved 308 patients. Diffuse large B-cell lymphoma was the commonly observed histological type, found in 214 patients; followed by a Follicular Lymphoma and Extra-Nodal NK/T‑Cell Lymphoma, Nasal Type. Following the extension workup; patients were all staged according to the ANN ARBOR classification; with a 77.8% of them were localized stages I and II, and of the therapeutically evaluable cases, complete remission was achieved in 112 patients. Conclusion: Our study focused on all extra-nodal localizations of NHL in the head and neck region. Due to the very heterogeneous nature of these tumors, most of the current studies are limited to a specific site of involvement. Nevertheless, our study provides an overall picture; which those specific studies can be based. The management of NHL has evolved considerably in recent years, insisting on the multidisciplinary character to a better management of these patients.
