Instrumental support for increasing personal resilience against destructive manipulations
Статья научная
The article confirms the possibility of metaphorical description by clients of options for manipulating their behavior that are significant to them. It has been shown that Sandplay Therapy can be used to successfully design and rehearse the desired forms of behavior and form associated sensory standards for subsequent ideomotor training. Evidence is presented of the validity of an assumption that the very elements of such materialized displays of the existing orientation schemes and their photographs support to quickly assess the intensity of the emotional experiences accompanying such modeling and the physiological processes associated with them. It has been established that cardiac measurements followed by calculation of the stress index of the various components of the autonomic nervous system make it possible to assess the level of stress caused by the client’s imagination of a problematic situation for him/her, where he/ she is facing a traumatic manipulation. It is noted that measurements of changes in galvanic skin reactions also allows judging the intensity of experiences that accompany the rebuilding of the associative connection of the depicted items with those manifestations of manipulation of which it is a metaphorical representation. Another assumption has also been confirmed that Sandplay Therapy can be used to effectively prevent some undesired manipulative influences on the client’s personality. At the same time, in addition to establishing the effectiveness of therapeutic procedures, cardiometric measurements and recording of electrodermal activity for the client himself/herself serve as a kind of bio-feedback. Using the latter, the client gets an opportunity to assess how much the response to metaphorical representations of manipulative influences corresponds to how exactly he/she would like to act if they are detected.

At the present stage, the introduction of technological inno-vations into medical practice is extremely important because it allows to increase the effectiveness of both diagnostic pro-cedures and the process of providing medical care to patients. At the same time, certain innovative technologies can radically change the landscape of medical procedures. Of particular in-terest in this context is the specialty of a trauma surgeon, where the innovations under consideration make it possible to im-prove patient treatment results, reduce complications, reduce recovery time and increase the experience of surgeons. Robotic surgery has become a significant breakthrough in modern medicine in general and in the practice of a trauma surgeon in particular. This technology allows surgeons to per-form complex operations with high precision and minimal im-pact on surrounding tissues, which contributes to faster recov-ery of patients and reduces the risk of complications. Robotic systems ensure the precise execution of surgical movements, robots allow surgeons to perform movements in a wider range than is possible using human hands. In addition, through the use of these systems, the surgeon, through the use of three-di-mensional cameras, receives a good visualization of the surgical field. Accordingly, the purpose of this work is to study the fea-tures of integrating modern technologies into the practice of a trauma surgeon.

Intelligent digitalization of cardiovascular risks
Статья научная
The aim of the study was to develop a mathematical model of the risks of the cardiovascular system based on the selected factors affecting cardiovascular diseases (CVD) and to test the developed mathematical model on a sample of clinical examples. CVD risk factors was grouped by types: biological indicators (anthropometric, biochemical, morphological, physiological), disease indicators, social indicators. An assessment of the degree of risk for each of the indicators was carried out by calculating the degree of risk using the membership formula, then evaluating the hazard class (according to the degree of risk) using a logical-linguistic model and a training algorithm for the neural fuzzy classifier of the network. The correctness of the risk determination by the developed model was confirmed by the analyzed 60 verified cases of acute cerebrovascular accident (18 men and 42 women). The analysis of the test results of the constructed neuro-fuzzy classifier allows us to conclude that it works satisfactorily even when using incomplete information, which makes it possible to use it for prompt decision-making. The results of testing on clinical examples, with an acceptable level of significance of a type I error of 0.05, showed that the risk was determined correctly. The factors influencing the risk of CVD are identified and designated as the corresponding linguistic variables. A logical-linguistic model was built, from which a transition was made to a hybrid neuro-fuzzy classifier, which allows assessing the influence of the identified factors on the level of risk of CVD. As a result of approbation of the model of intellectual digitalization of risks of the cardiovascular system on real clinical examples, it was confirmed that the risk was determined correctly, which means that it is possible to assert about the prospects for introducing this model into clinical practice and guaranteeing medical specialist more accurate diagnosis and optimization of their activities.

Interdisciplinary educational approaches in healthcare organizations
Статья научная
Background: Healthcare professionals’ perception of Interdisciplinary Education is an essential factor that affects their acceptance of this approach to education. From the literature related to patient safety, it has been identified widely that healthcare team communication and performance are critical to providing safe care to the patient. Poor organization and team dynamics among healthcare professionals appear to impact the safety and quality of patient care. The lack of Interdisciplinary Education in healthcare institutions in the Kingdom of Saudi Arabia negatively impacts the work dynamics of the healthcare team. Results: The study results showed that the majority of health care workers showed a high awareness level for IPE. Therefore, female nurses who have been working in special units and have experience of more than five years are perceived more than other specialties. Also, health workers in special units showed a higher percentage than in the general wards, and females were ready more than males. Only one item helped to determine the differences in perception which is the “perceived need for cooperation”. Conclusions: IPC should be initiated by universities than by health organizations starting at the level of leaders of medicine, nursing, and other disciplines who should be aware of the importance of IPC that would benefit patients as well as health institutions. Leaders must take IPC cooperation seriously by putting it into consideration in the vision of departments and thus starting to establish small-cooperated teams, which include various specialties.

Degenerative brain diseases (DBD) and other cognitive dysfunctions may appear due to the depletion of adaptive reserves as a result of aging, stress, depression, and other pathological processes (inflammation, malignant neoplasms). The depletion of the adaptive reserves leads to disordering accurate, appropriate signaling in the brain, between the brain and the body, as well as disorders at the levels of the organs, cells and molecules. The body's adaptive reserves ultimately determine the tolerability or the resistance to various degrees of hypoxia, which accompanies stress, trauma, depression, inflammation, and aging. Oxygen is the most important and fastest regulator of metabolism. The fundamental concept is as follows: optimal health is activated and stimulated by intermittent stimulation, i.e. moderate functional loads [1, 2]. We offer practical programs, which combine two non-pharmacological natural methods of activation therapy, training aimed at improving the adaptive reserve of the human body: intermittent fasting treatment (IFT) and interval hypoxic training (IHT).

Intermittent hypoxia as a method of training and treatment
Отчет
For centuries, the scientific community has been aware of the cellular importance of oxygen, which converts food into energy and is transported to the tissues by red blood cells. It is known that oxygen gives life and life energy and takes them away.Training with intermittent hypoxia, interval hypoxic training (IHT) is one of the most promising additional non-drug therapies that activate the natural defences of the human body and provide the body with a high degree of adaptation.

Intermittent hypoxic training as an effective method of activation therapy
Отчет
This article considers possibilities of achieving the most effective therapeutic effect of intermittent hypoxia training (IHT) by initiating an activation and training reaction. Thanks to IHT the body builds an anti-stress type adaptation which increases the body's nonspecific resistance to the development of diseases. It works through a variable functional load which includes a mechanism for optimizing mitochondrial respiration and is a trigger for synchronizing the performance of the nervous, immune and hormonal systems. Some biochemical data presented in the article demonstrate the effects of moderate hypoxia. In addition, laboratory and hardware methods of diagnosing for the selection of individual IHT regimes are proposed. IHT is used to great effect in training of astronauts, pilots, athletes and in the treatment of diabetes mellitus, trophic ulcers, diseases of the cardiovascular system, the central nervous system and oncological disorders as well as for rejuvenation purposes.

Internship in the year of COVID-19: what has changed in internship dynamics?
Статья научная
The purpose of this research is to understand the changes in internship dynamics of MBA students in 2020 who undertook virtual full-time internships as compared to previous years when interns were required to be present physically. Sample was collected from two set of interns; one set interns were working through virtual internship and the second set were working on traditional model of on- site internship. For data collection, structured questionnaire was used. Data was collected on various parameters of internship processes and experience. The result from the current findings suggests that the experience of both set of interns differ significantly. This paper will essentially evaluate whether virtual full-time internships have been able to contribute, create & shape internship experience effectively for interns & understand which dimensions such as learning, productivity, communication, etc have seen changes due to the nature of work being changed. Research material in this area is limited, mainly due to students experiencing a remote working style in their internships for the first time which is why this research will be quite valuable for various stakeholders.

Intracellular electrophysiological evidence: how pain is experienced by neurons
Статья научная
Aims. The aim hereof is to identify changes in the performance of the CNS neurons under the prolonged action of low-threshold pain factor according to indicators of the membrane potential level, parameters of the action potential and the pattern of the firing activity distribution of the neurons. Materials and methods. As a model, functionally active neurons of the central nervous system in the grape snail Helix pomatia were selected as an integral part of the organism in vivo. Used has been the author’s original electrophysiological method of continuous recording of intracellular biopotentials of animal neurons both under the background conditions and by applying a long-term low-threshold action (LTA) to the main nerves due to a graded pressure to produce a pain effect of the subthreshold level that over time turns into increasing pain. Results. For the first time in world science, objective evidence for the long-term low-intensity action of pain on the electrophysiological characteristics in a CNS neuron has been obtained. Revealed are the changes in the amplitude and the action potential firing rate, the membrane potential level and the pattern of the neuron pulse activity, traced continuously, up to full neuron potential turning-off. It has been detected that, when removing the pain factor, there are some points of return to the norm available, and, in case of longevity of the pain action, the functional state of the neuron passes the point of no return, after which the neuron electrophysiological potentials reach zero value, indicating the cessation of its life. Conclusions. The dynamics of the neuron functional state in vivo, under prolonged action of the pain factor, reflects nonlinear changes in the membrane potential, firing rate and amplitude of AP. This characterizes the phase process of forming a pathologically stable pain state of the neuron, despite the readiness of the membrane mechanisms at the transition points to a response aimed at returning to life. The evidence obtained in our experiments provides more insight into the mechanisms of chronic neurogenic pain in experimental and clinical medicine, as well as the diagnostics of the brain death.

Research methodology and methods used in experiment Mars-500 held at the Institute of Biomedical Problems of the Russian Academy of Sciences in 2009-2011 are considered. 6 volunteers were isolated during 520 days in a sealed ground-based facility simulating space ship. Along with studies of the Martian crew, a number of satellite research were also carried out, which were devoted to the long-term program of medical and ecological investigations. This program was aimed at the study of the dynamics of adaptation abilities of the organism during its long stay in the natural social, living and industrial environments. For physiological investigations in experiment Mars-500, including the main experiment in a sealed ground-based facility and parallel long-term medical and ecological investigations in different regions of the world, the specialized hardwaresoftware complex "Ecosan-2007" was used. The methodology was based on the principles of prenosological diagnostics that have been further developed in the concept of adaptation risks and in the probabilistic approach to their evaluation. For evaluation of various components of the autonomous regulation state the method of heart rate variability (HRV) was used. It was concluded that the most important field in experiment Mars-500 was the investigation of the methodology of prenosological diagnostic in the preparation of a space mission to Mars.

In order to evaluate the vegetative regulation of blood circulation and assess individual health risks under conditions of the 520 day isolation, used was an analysis of the heart rate variability (HRV). The most significant changes in the HRV values against the background data were reported in the second half of the said experiment. At that time, the heart rate (HR) values showed some reductions, the standard deviation of normal-to-normal beats (SDNN) was increased, and the simultaneous activation of all regulation members (pNN50 – parasympathetic regulation, IC and VLF – the sympathetic and neurohumoral regulation) occurred. The period of “the Mars orbiting”, the time of the crew dividing and “the landing to Mars” featured the highest level of the tension of the regulatory systems and the significant increase in the health risks. An assessment of the functional state of the organism and the adaptation level according to the degree of the tension (DT) of the regulatory systems and their functional reserve (FR) made it possible not only to confirm the presence of the changes identified by the commonly used HRV, but to make them more apparent as well...
