The aim was to analyze the contemporary scientific literature on Devic’s opticomyelitis and to present a case report from our clinical practice. Based on the patient’s complaints, case history and features of clinical course, objective neurological status, clinical laboratory and additional examination methods, characteristic MR-patterns, consultations of related specialists and differential diagnostics, we made the clinical diagnosis according to ICD-10: G36.0 Devic’s opticomyelitis, exacerbation, with a sustained bilateral lesion of the optic nerves in the form of retrobulbar neuritis with the development of partial atrophy of the optic nerves in both eyes, spinal cord lesions with common cystic, cicatrical and atrophic alterations at C1-Th8 level with moderate lower paraparesis, expressed by sensory ataxia, sensory disturbances by the descending conductive type from Th10, impaired function of pelvic organs by the type of acute urinary retention, asthenic and neurotic syndrome. Widespread cases of demyelinating pathology in medical practice and complexity of differential diagnostics determine the need for a specific diagnostic algorithm. This algorithm should consider anamnestic data along with the course of the disease, clinical, laboratory and instrumental examination, including neuroimaging, analysis of CSF for oligoclonal bands, analysis for IgG antibodies to AQP4, which will allow to carry out diagnostics and to decide on tactics for further management of patients of this cohort. Further research is needed to conduct additional studies for optimization of tactics for dynamics monitoring and improvement of diagnostic, treatment and rehabilitation measures in patients with Devic’s opticomyelitis, including appropriate immunological control, given the complexity of differential diagnostics and the affinity of this pathology to multiple sclerosis.

Published: April 2021

The aim: To analyze the nutritional knowledge of women in the reproductive age about nutrients influencing the fetal nervous system’s development.
Materials and methods: The study was conducted with a proprietary anonymous questionnaire using the CAWI (Computer Assisted Web Interviews) method among 263
women aged 18-51 years.
Results: In 35.4% of the surveyed women, the level of knowledge was insufficient, in 31.9% – sufficient, in 27% – good, and only in 5.7% – very good. The knowledge of the
respondents was influenced by education (p < 0.001) and body mass index (BMI, p < 0.001). Women of reproductive age with higher education and/or lower BMI had a better
understanding of nutrients influencing the fetal nervous system’s development. Age, place of residence, family status, and professional status did not affect their knowledge.
Conclusions: The study showed that it is necessary to conduct nutritional education among women of reproductive age. Increasing the respondents’ awareness of the importance of nutrients determining the fetus’s proper development, both during the reproductive period and during pregnancy, is extremely important.

The aim: To assess the quality of life in women after mastectomy.
Materials and methods: The study included 25 women after mastectomy. The patients were aged 31 to over 50 years and were members of a breast cancer support group at
the Holy Cross Cancer Centre in Kielce. During group meetings, the patients underwent rehabilitation and worked with psychologists and social workers.
Results: Most women after mastectomy who underwent breast reconstruction or wore breast prostheses reported a better quality of life. Mastectomy affects ipsilateral upper
limb function and causes difficulty with activities of daily living, such as cleaning, cooking, brushing hair, bathing, and dressing.
Conclusions: 1. All women who rated their health as poor experienced such negative emotions as sadness, low mood, dejection. 2. Mastectomy affects ipsilateral upper limb function. 3. Breast reconstruction after mastectomy improves patient-rated quality of life. 4. Pain in the ipsilateral upper limb is considerably more common in women with a limited range of motion. 5. All women who participated in breast cancer support group meetings found support there and the time they spent together resulted in an improved quality of life.

The aim is to determine the clinical and morphological dependencies, which are important for diagnostics, treatment and prediction of outcomes of pathological processes in the region of the LTM with complicated eruption, as based on the study of histopathological changes of paradental tissue (mucous membrane, walls of retromolar pocket, alveolar bone tissue). Materials and methods: The materials of the study were 34 biopsy specimens of pathologically altered soft tissue and parodontium obtained as a result of pericoronectomy, extraction of the LTM and other surgical interferences performed based on the relevant indications in 28 patients in the region of the LTM with complicated eruption. Morphological and statistical research methods were used. Results: The local pathological processes, which chronologically precede the destructive changes in the hard tissue of a tooth (caries), are developed in patients of both genders with complicated LTM eruption in soft tissue of parodontium and the adjacent bone tissue of the alveolar wall in the majority of cases. As per biopsy examinations, the frequency of the main pathological processes in paradental tissue in case of complicated LTM eruption varies from 25 to 60 % of the number of biopsy specimens and occurs in various combinations in patients with different values of clinical parameters. The correlation relationships between the patients’ clinical data and the morphological parameters of damage to paradental tissue are weak, multidirectional and uncertain in the majority of combinations (considering the available number of biopsy specimens studied). The close certain positive dependence between the damage of the squamous epithelium and the inflammation activity in the lamina propria mucosae, covering the tooth: in the vast majority of cases, the presence of damaged epithelium (within the biopsy specimen) is associated with the inflammation of high activity, was established as based on correlation relationships between the morphological parameters of damage to paradental tissue. Conclusions: The found pathological changes and the correlations justify surgical tactics on paradental soft and osseous tissues that are directed on the LTM sparing.

The aim: To evaluate the relationship of certain alleles of HLA class II leukocyte antigens and the profile of antibodies to various subunits of nicotinic acetylcholine receptors (nAChR), the level of Treg lymphocytes and the serum concentration of anti-inflammatory IL-10 for various clinical myasthenia gravis phenotypes.
Materials and methods: We examined 217 patients with thymus-independent myasthenia (n = 42) and thymus-dependent myasthenia, among them patients with thymus hyperplasia (n = 108) and thymoma (n = 67). We used the following methods: ELISA, flow cytometry, light and fluorescence microscopy.
Results: Certain genomic (polymorphism of leukocyte HLA-DR antigens) and epigenomic (antibodies to α1 and α7 nAChR subunits, expression of Treg lymphocytes and concentration of cytokines) predictors were identified for various myasthenia phenotypes. The presence of HLA haplotypes DR2 and DR7 in some young patients with M with disease progression led to the development of myasthenia gravis with thymoma (MT) at an older age. The presence of α7 nAChR subunit on thymocyte mitochondria was revealed, which is an additional autoimmune target for autoantibodies in patients with myasthenia gravis. An increase in the concentration of cytokines (IL-4, IL-8, IFN-γ) in all patients with myasthenia gravis was revealed.
Conclusions: Estimate the features of the formation of various variants of the immune response in thymus-independent and thymus-dependent myasthenia gravis is a necessary condition for targeted immunocorrection or surgery.

The aim: To clarify the efficacy of probiotics use as a preventive measure for post-antibiotic treatment in acute peritonitis and increase staff awareness related to antibiotic and probiotic use.
Materials and methods: The study design included determination of the proper antibiotic and probiotic strain combination and clinical application of probiotic strains. The control group consisted of 63 (48.46%) patients who underwent traditional multimodal treatment of peritonitis and the study group of 67 (51.54%) individuals, with inclusion of different antibiotic/probiotic combinations.
Results: Prior to antimicrobial therapy 67.7% patients of both groups’ patients had severe dysbiosis, proving dysbiosis as a sign of peritonitis. S. boulardii showed widest resistance spectrum and was used for probiotic therapy in study group. Intestinal dysbiosis grades distribution in control group significantly worsened, while in study group ratio of severe dysbiosis significantly dropped from 58.2% to 38.8% with significant growth of grade II dysbiosis to 61.2%. No visible differences in disease course and clinical picture, duration or complications rate between study and control groups were observed.
Conclusions: Most of probiotic strains lack antibacterial resistance that makes meaningless their use during systemic antibiotic therapy of acute peritonitis. It is characterized by harsh changes of intestinal microbiota (severe intestinal dysbiosis). While probiotic strains showed antibiotic tolerance, their use presented no significant clinical efficacy, though high level of positive influence on intestinal dysbiosis was observed.

Published: April 2021

The aim: To increase the effectiveness of treatment of sinusitis polyposa patients, develop and introduce a new non-traditional complex method of influencing several links of the pathogenesis of this disease, including laser therapy and laser puncture, used in the postoperative period.
Materials and methods: In 60 rhinosinusitis polyposa patients the indicators of lipid peroxidation and the state of antioxidant protection were studied. Depending on the
type of treatment, the patients were divided into two groups: the first included 30 people who underwent traditional surgical intervention, and the second – 30 people who used complex therapy, including in the postoperative period endonasal laser exposure and laser puncture.
Methods: clinical data, the functional state of the nasal mucosa, indicators of lipid peroxidation (hydroperoxide, malondialdehyde) and antioxidant activity (glutathione peroxidase, glutathione reductase, reduced glutathione, superoxide cismutase, catalase) of erythrocyte membranes and blood serum were studied.
Results: The proposed complex method for treating lipids of erythrocyte membranes and serum, which includes endonasal surgical intervention, endonasal laser therapy and laser puncture leads to the normalization of physiological functions of the nose, activates antioxidant protection and reduces the peroxide activity of lipids in the membranes of erythrocytes and blood serum.
Conclusions: When examining patients in the long-term (after 1 year) period, a significant improvement in 85.7% of cases, an improvement in 10.7%, and absence of effect in 3.6% was achieved. Thus, the proposed method of therapy can be recommended for widespread use in medical institutions.

Authors: Dyachuk Dmytro D. , Gandzyuk Volodymyr A. , Zyukov Oleg L.
Published: April 2021

The aim: Study of the indicators of quality of life of patients served by a multidisciplinary health care institution with the functionally-organizational model of coded prevention
of chronic noninfectious diseases is implemented.
Materials and methods: To evaluate the effectiveness of the model's use we used the assessment of the dynamics of QL indices, which was assessed according to the EUROHISQOL
8-item index methodology among 376 patients aged over 18 years.
Results: Most of the respondents (61.4%) were dissatisfied to varying degrees with their state of health and, on average, evaluated their QL (56.1%). ЗThe overall assessment
of the quality of life of the surveyed population was on a 20-point scale of 13.5 (3.19) points in 2017 before the introduction of the program of managed prevention of СNCDs
and 14.6 (3.48) points after its three-year operation, with an increase integrated indicator on average by 1.1 (95% CI 0.59 – 1.60) points (p <0.001). Among the areas of QOL
assessment, the assessments in the physical sphere and the environment increased at most (p<0.05). It is determined that the overall level of QOL of patients with NCDs is 40%
due to medical and social factors that can be positively influenced by medical care using a model of managed prevention.
Conclusions: The analysis of changes in the quality of life of patients of multidisciplinary institutions who have risk factors for СNCDs or suffer from chronic non-communicable
diseases, showed that the introduction of a functional-organizational model of managed prevention at the health care institution level can improve integrated assessment of
QOL and positively affect the overall complex of medical and social factors, including managed risk factors. This indicates the effectiveness of this model of managed prevention at the level of a multidisciplinary health care institution.

Dünya iqtisadiyyatında Çin fenomeni
Authors:   DES, Professor, Hajizadeh Elshan
Published: April 2021

Dünya təcrübəsi göstərir ki, iqtisadi və siyasi islahatlar uzunmüddətli mürəkkəb bir proses kimi hər bir ölkənin həyatında özünəməxsusluğu ilə təcəssüm olunur. Bu baxımdan hələ də prosesin meyar və ölçülərini dolğunluğu ilə əks etdirən müqabil vahid konsepsiyanı formalaşdırmaq mümkün olmamışdır. Bu çətinliyi həm də ayrı-ayrı ölkələrdə baş verən bir sıra iqtisadi uğur fenomenləri və onunla bağlı bu sferada iqtisadi tsiklin başa çatmaması kimi amillər daha da mürəkkəbləşdirir. Belə fenomenlərdən biri də dünya iqtisadiyyatının son 30 ildə ən mühüm hadisələri sırasında yer alan Çin iqtisadiyyatının bənzərsiz inkişaf uğurları hesab olunur. Hadisənin fövqündə əksəriyyətinin memarı hesab etdiyi Çin Kommunist Partiyasının görkəmli xadimi, inqilabçı, siyasətçi, islahatçı Den Syaopin şəxsiyyəti dayanır. Dağıdıcı sosial və siyasi çəkişmələrdən sonra ölkəyə rəhbərlik edən Den Syaopin «Çin xüsusiyyətliyi ilə sosializm» prinsipi adı altında yeni sosialist təfəkkür formalaşdıraraq geniş miqyaslı iqtisadi islahatların təşəbbüskarı kimi ölkəsini dünya bazarının bir hissəsinə çevirdi. Çin bununla da dünyada ən sürətli iqtisadi inkişafa malik bir ölkə nüfuzu əldə etdi. Bu iqtisadi inkişaf prosesi təkamüllü olmaqla, həm də o qədər sıçrayışlı və geniş səmərədə nəticəli idi ki, tezliklə onu Çin «iqtisadi möcüzəsi» adlandırdılar.

An algorithm is constructed to approximate a zero of a maximal monotone operator in a uniformly convex anduniformly smooth real Banach space. The sequence of the algorithm is proved to converge strongly to a zeroof the maximal monotone map. In the case where the Banach space is a real Hilbert space, our theorem com-plements the celebrated proximal point algorithm of Martinet and Rockafellar. Furthermore, our convergencetheorem is applied to approximate a solution of a Hammerstein integral equation in our general setting. Finally,numerical experiments are presented to illustrate the convergence of our algorithm.

We present the local as well as the semi-local convergence of some iterative methods free of derivatives for Banach space valued operators. These methods contain the secant and the Kurchatov method as special cases. The convergence is based on weak hypotheses specializing to Lipschitz continuous or Holder continuous hypotheses. The results are of theoretical and practical interest. In particular the method is compared favorably ¨ to other methods using concrete numerical examples to solve systems of equations containing a nondifferentiable term.

In this paper, we study polynomial functional equations of the form af(p(x)) + bf(q(x)) = g(x), where p(x), q(x) are given polynomials and g(x) is a given function. Theorems 21 and 22 contain sufficient conditions under which the functional equation has a solution of the special form. In Section 3 we present an algorithm of constructing polynomial solutions of the functional equations. Other non-polynomial solutions depend on solutions of the homogeneous equation af(p(x)) + bf(q(x)) = 0. That case is analyzed in Section 4. Finally, we present a simple method of constructing examples with desirable properties.

Conflictividad agraria e izquierda en una Argentina convulsionada, 1970
Authors: Lissandrello Guido
Published: April 2021

En este artículo examinamos la relación entre un actor político (el Partido Comunista) y un actor social (las Ligas Agrarias), durante la convulsionada década de 1970 en Argentina. Mientras que el primero fue uno de los partidos de izquierda más longevos del país, el segundo corresponde a un movimiento social complejo, que surgió en una coyuntura de crisis económica y de importantes transformaciones tecnológicas y productivas en el agro. Otros estudios sobre organizaciones políticas de la etapa se centraron en sus vinculaciones con actores sociales urbanos, lo que opacó las relaciones que se tejieron con sectores rurales, que no escaparon a la tónica de protesta de la época. En la línea de saldar ese déficit, estudiamos este partido que fue el que mayor atención le brindó al campo, para comprender cómo se vinculó al movimiento liguista y cómo lo caracterizó desde lo teórico. A partir del estudio de sus documentos internos (actas congresales) y públicos (revistas teóricas y periódicos), reconstruimos su defensa de un campesinado argentino, atendiendo a las contradicciones presentes en dicho proceso. Este acercamiento iluminaría, desde otro ángulo, un problema historiográfico vigente: la naturaleza social de las Ligas Agrarias.
Democracia y aparato represivo en Brasil durante el Gobierno de Luis Inácio “Lula” da Silva, 2003-2010
Authors: Pezzarini Martín
Published: April 2021

En el presente trabajo se analizan algunas de las principales características de las fuerzas represivas del Estado durante la gestión de “Lula” da Silva (2003-2010) y, al mismo tiempo, se examinan los asesinatos de activistas a manos de fuerzas estatales y paraestatales, prestando especial atención a los casos que se registran en el ámbito rural. Para ello, se emplea una metodología cuantitativa a partir del uso de diferentes fuentes. Por un lado, se apela a los datos que publican distintos organismos estatales como el Ministerio de Planeamiento, Presupuesto y Gestión, el Ministerio de Justicia y el Ministerio de Hacienda. Por otro lado, se emplean fuentes secundarias, como artículos periodísticos e información publicada por organizaciones de la sociedad civil, como el Foro Brasileño de Seguridad Pública, la Comisión Pastoral de la Tierra (CPT) y el Instituto de Geografía de la Universidad Federal de Uberlândia. De este modo, se caracteriza el fortalecimiento del aparato represivo y la evolución de activistas ejecutados durante los años bajo estudio, demostrando que el empleo sistemático de la violencia y la represión política son compatibles con el sostenimiento del régimen democrático.
Los grandes retos para la democracia ecuatoriana en la era poscovid-19
Authors: Paredes Ana Marcela
Published: April 2021

Ana Marcela Paredes, una de las cordinadoras de este número, entrevista a Manuel Alcántara Sáez. En la siguiente entrevista el profesor Alcántara reflexiona acerca de los retos para la democracia en el contexto iberoamericano. Se exponen ideas de actualidad con relación a los consensos mínimos necesarios para la era poscovid-19 en países como Ecuador, que en pocos meses contará con una nueva presidencia y parlamento. Desde un sentido crítico aborda los grandes desafíos que enfrenta la sociedad ecuatoriana, tales como la fatiga de la democracia, el uso de las tecnologías para nuevas formas de participación y la proliferación de organizaciones políticas que sitúan a Ecuador como el país con más organizaciones de este tipo en la región. La fatiga de la democracia a la que se refiere en varias de sus publicaciones es el resultado de una serie de cambios de las sociedades modernas, en los que el rápido desarrollo y difusión de las nuevas tecnologías de la información y de la comunicación desempeñan un papel notable, lo que da como resultado la polarización, tensiones y demandas entre actores sociales y políticos.
Attenuation of airborne noise by wet and dry neoprene diving hoods
Authors: Paddan Gurmail S , Lower Michael C
Published: April 2021

The insertion losses of five neoprene diving hoods of varying thicknesses (2 mm–9 mm) were measured in one-third octave bands using a Kemar manikin in a diffuse broadband noise field. The insertion losses were measured in air for both dry and wet hoods. The insertion loss was
calculated as the sound level in each frequency band measured with the hood, minus the corresponding sound level measured without the hood. The insertion losses were similar for both ears of the manikin. Both wet and dry hoods neither attenuated nor amplified sound below 250 Hz. Between 315
Hz–1250 Hz, the insertion loss of each hood was negative, displaying a broad resonance with a gain of 6–8 dB. In this frequency range the hood acts as a mass-spring system, resonating like a drum skin when stretched over the ears. Above 1000 Hz, the insertion loss increased with
frequency (10 dB per octave), reaching a maximum of 5000 Hz–6000 Hz. Wetting each hood did not significantly affect the insertion loss; the 'drum-skin' resonance frequency was marginally lower with a wet hood, and insertion losses may be marginally greater between 1000 Hz– 10 000
Hz. The resonance frequency decreased with increasing thicknesses of hood, and the insertion loss at frequencies above the resonance increased with hood thickness.

Interdisciplinary Research Methods: Considering the Potential of Community-based Participatory Research in Translation
Authors: BOWKER LYNNE
Published: April 2021

Abstract Different disciplines have different research traditions, including the use of discipline-specific research methods. However, adopting methods from other disciplines can provide fresh perspectives and lead to new insights. Community-based participatory research (CBPR)
originated in the population and public health field, but it has potential to be applied in a broader range of disciplines. This article explains the fundamental characteristics of CBPR, explores some misconceptions associated with this method, and describes some potential barriers to its
application. Finally, using the example of a machine translation literacy project, the article walks readers through this example of how CBPR was applied to a translation- related research project and evaluates the success of this method for the project.
Learning to Bridge the Divide: Integrating Teacher and Organizational Development in Translator Education
Authors: MASSEY GARY
Published: April 2021

Abstract Translation pedagogy has evolved into a new sub-discipline of translation studies, but the focus has been almost exclusively on student competences and their development rather than on those actually doing the teaching. The multiple challenges presented by technology,
digitalization and socio-ethical concerns have been lending increased impetus to diversifying the roles and working contexts in which translators pursue their vocation, calling for a review of translators’ roles and competences and a re-orientation of translator education. Yet, the concomitant
need to model the competences and development of those educating the future professionals has received far less attention. After considering current and future challenges in translation practice and teaching, the present paper focuses on a use case from the author’s institution to propose
an integrated approach to teacher competence development, framed by influential approaches to organizational learning and operationalized in a situated, localized directive which set out to make efficient and effective use of available resources as key affordances in teacher development. These
include participatory action research and experiential learning measures designed to promote and incentivize reflective practice, innovation and thus bridge the much-cited divide between professional vocational training and the academic objectives of translation theory and research.
Evaluation of the thermal factor in the vacuum therapy
Authors: Kasperczyk Tadeusz , Walaszek Robert , Marszałek Anna
Published: April 2021

Introduction: The aim of the work was to analyse changes in values of temperatures measured inside the cup and on the surface of the skin in the place where the cup was applied, using two slightly different variants of applying hot glass cups.
 Methods: The temperature
was measured using two measuring instruments, the so-called multimeters, which were connected by wires with two K-type probes (thermocouples). One of them measured the temperature of the skin covered by the cup, and the other – the temperature inside the cup.
 Results:
In variant I at the beginning of the test the temperature of the interior of the cup was 48.4°C, and of the skin inside the cup was 40.3°C. The difference between the temperature inside the cup and the temperature of the skin was therefore 8.1°C, i.e. 16.7%. In variant II, the
temperature of the inside of the cup and of the surface of the skin were similar and amounted to 42.2 °C and 43.9 °C respectively. It means that right after applying the cup, the body temperature in the place of its application increased by 7.3°C, i.e. by 19.8% in relation to the
normal body temperature.
 Conclusions: The experiment that was carried out allows us to claim that the applied vacuum therapy affects the tissues by two factors: vacuum pressure and heat, and that is why the hot cup should be considered more effective in the therapy than the
cold cup.

Yamamoto New Scalp Acupuncture (YNSA) has been used in clinical practice for pain symptoms worldwide. However, the safety of YNSA and the role of the diagnosis and stimulation points have never been investigated. This study aimed to investigate the safety of YNSA and the relationship
between the diagnosis points, the stimulation points, and changes in shoulder stiffness. YNSA was performed at the shoulder point A, acupuncture at the non-shoulder point D, and no intervention as a control in 15 healthy participants three times with a washout period of 1 week. Adverse reactions
(changes in blood pressure, changes in heart rate, or bleeding), objective evaluation of the pressure pain threshold (PPT) and muscle hardness (MH) scores at the shoulder, and subjective evaluation of shoulder stiffness with a visual analog scale (VAS) were recorded before, during, and 20
min after stimulation. In the safety evaluation, no adverse reactions such as hypotension, bradycardia, or bleeding/hematoma were observed. PPT and MH revealed no significant difference between the conditions. There was a significant difference in the VAS between all three conditions (p
= 0.039). Post-hoc analysis showed a significant difference between controls and D-point stimulation (p = 0.034), but no significant difference between A- and D-point stimulation. VAS subanalysis and post-hoc analysis in right-LI4-positive subjects (n = 4) showed a significant difference
in VAS between A-point stimulation and controls (p = 0.01, 0.015, respectively). Our pilot investigation exhibited the safety of YNSA. Diagnosis and stimulation points may relate to changes in shoulder stiffness; however, further comparative studies with YNSA are required.

Do Korean Restaurants Influence People to Travel to Korea?
Authors: Jeon Sanghyb , McKercher Bob
Published: April 2021

This study examines the role of dining in local ethnic restaurants as a push factor in motivating people to visit the cuisine's country of origin. A study was conducted on Hong Kong residents who ate at a local Korean restaurants. The study found that dining in restaurants stimulated
a desire to visit, regardless of whether respondents had visited Korea previously. Past visitors also found that they ate more frequently in local restaurants after their trip. However, food is only part of the reason. Dining in Korean restaurants represents an embodiment of Korean culture
and tradition, enabling people to gain an authentic Korean experience. In doing so, they became more motivated to visit the country.
MEDICAL AND EPIDEMIOLOGICAL CHARACTERISTICS OF PROXIMAL FEMUR FRACTURES IN CITY OF KHARKIV AND KHARKIV REGION POPULATION
Authors: Hurbanova T. S.
Published: April 2021

Regional clinical and epidemiological characteristics of the patients with the proximal femur fractures have been determined. To perform the research, the following tasks were solved: to establish the prevalence of fractures of the proximal femur depending on age and sex characteristics, place of residence, lesion, features of admission to the clinic, mechanisms of referral, timing of admission, concomitant pathology and comorbid burden, functional level, type of fracture and treatment tactics. The regional epidemiological characteristics of patients with these fractures were retrospectively studied using the date of seven medical institutions of the city of Kharkiv during 2011−2016. The predominance of women with a total average age of all the patients of 70.36±0.20 years and the one of the contingent of the patients aged 71−80 years and older 80 years and older were found. There was a significant prevalence of urban dwellers among the patients. The predominance of patients admitted to trauma departments by ambulance crews was determined. It was stated that the vast majority of respondents received medical care in the first 6 hours after injury. A significant proportion of comorbidly burdened patients with a predominance of the patients with one or two concomitant diseases was identified. Almost identical injuries of both the right and left extremities with a significant predominance of closed fractures and those of type 31A1 and 31B1 according to the classification of the Society for the Study of Osteosynthesis. A certain decrease in functional status was determined according to the classification of the American Society of Anesthesiologists. Conservative treatment was used more often than surgical treatment. Key words: proximal femur fractures, clinical and epidemiological characteristics, concomitant pathology, comorbid burden, age−sexual characteristics, functional status.
