Published: November 2024

At the moment the globality of its information fi eld became obvious, the information society virtually removed from the agenda the question of the existence of tradition and traditional culture within its borders. Certainly, their importance was not denied and, moreover, against the backdrop of increased ethnic activity, it increased signifi cantly. This is evidenced by UNESCO's attention to the protection of the world's cultural and natural heritage (World Heritage List, 1972), to issues of copyright in the fi eld of culture and creativity (World Culture Report, 1998. “Culture, Creativity and Markets”), the inclusion of intangible aspects in the concept of cultural heritage, including traditions and practices, beliefs and perceptions, languages and dialects, music, singing, dancing, and storytelling (Universal Declaration on Cultural Diversity, 2001). It is important to note that back in 1998, the World Culture Report considered cyberculture as a subject of copyright. This fact alone indicates that the principles of construction and functioning of the information society were clearly visible not only in the sphere of technology, production, and communications, but in the creativity sphere as well.

The purpose of the research was to consider the infl uence of the geographical distribution of sable on the main commercial properties of its skins in the Irkutsk region. It is noted that the number of the species in 2023 was 266.7 thousand individuals. An analysis of 750 sable skins obtained in the western and northern parts of the region was carried out. The dependence of the fur quality on the geographical distribution of the species was analyzed. It was confi rmed that in batches of skins from the Nizhneudinsky, Tulunsky, Katangsky districts of the Irkutsk region, the share of light sables predominated (67–75 %). In the Kirensky and Kazachinsko-Lensky districts of the Irkutsk region, the share of dark sables was 58 and 59 %, respectively. It is indicated that in the Cisbaikalia region the general lightening of sable fur continues, explained by the proximity of the Katangsky, Nizhneudinsky and Tulunsky districts to the neighboring populations of lighter strains of the Krasnoyarsk Territory and the Republic of Tuva. The majority of the total batch of harvested sable skins were of the especially large size 46.5 %, the share of large sables was 22.1 %, 31.3 % of the skins of the studied batch were classifi ed as medium and small goods. The percentage of especially large skins was found in the Kirensky and Kazachinsko-Lensky districts of the Irkutsk region and was more than 50 %. The analysis of fur defects showed that the share of the norm among the model regions was almost equal and was 33–36 %. Most sable skins (38.7 %) had a small defect, the share of skins with a medium defect was 22.7 %, large was 4.3 %. The highest percentage of sable skins with major defects was found in the Kazachinsko-Lensky region.

At present, the increase in poultry meat production is associated with the development of resource- saving technologies that ensure maximum productivity. However, the search for new methods to reduce the rearing period, increase live weight and reduce feed costs per 1 kg of gain continues. It should be noted that at the current stage of development, poultry farming has a high productivity potential, which is currently not fully utilized in some cases. The main reason is the inclusion of ingredients containing anti-nutritional substances in the compound feed. In compound feed for broiler chickens, the need to use biologically active additives has been proven. The inclusion of such additives in the composition of compound feed helps to increase the productive action, improve digestibility and effi ciency of using nutrients in diets. The purpose of the research was to study the meat productivity and meat quality of broiler chickens when input additive of plant-based additive in compound feed. On the base of research data, the eff ectiveness of including the plant-based feed additive Biostrong 510 in the compound feed for rearing of broiler chickens of the cross Cobb 500 in the amount of 0.010 %, 0.015 and 0.020 % of the compound feed weight was established. It made possible to increase the average daily live weight gain by 4.3–8.5 %, increase the gutted carcass weight by 4.3–4.6 %, reduce feed costs per 1 kg of broiler chicken gain by 0.07–0.13 kg, and increase the profi tability level by 0.78–1.44 abs.%. The safety of the tested additive was proven by a number of indicators. The obtained results of animal science, physiological and biochemical studies made it possible to identify the optimal dose of the plant feed additive Biostrong 510 for broiler chickens of the cross Cobb 500 in feeding technology 0.015 % of the mass of the compound feed.

The purpose of the work was to evaluate the infl uence of inbreeding on milk productivity, reproductive traits and longevity of cows of Holstein breed. The studies were carried out under the conditions of the breeding farm Konstantinovo. The animals were divided into groups depending on the mating type such as outbreeding and inbreeding. Inbred animals were divided into groups depending on the level of inbreeding: remote, moderate and close. According to the results of the evaluation of the fi rst-calf cows by milk productivity, the highest milk yield, as well as the amount of fat and protein in milk was in cows from moderate inbreeding. It was found that the milk yield for the full and 305 days of lactation of inbred animals (9411 kg and 8408 kg) was higher compared to outbred animals by 1003 kg or 10.6 % and 1028 kg or 13.1 %, respectively. The yield of milk fat and protein in these groups was the highest 346.2 and 308.9 kg. The milk productivity of cows evaluated by the third lactation, the best indicators were in the group of animals with moderate inbreeding as well as in outbred animals. Thus, the milk yield for the full and 305 days of lactation was higher in the group of outbred cows by 876 kg or 9.0 % and 376 kg or 4.6 %. Analysis of reproductive traits of cows showed that live weight at fi rst insemination was higher in the group of inbred animals (373.4 kg), and higher compared to outbred animals by 0.7 %. The age in fi rst insemination in the group of inbred cows was lower by 2.1 months (p < 0.001). It was established according to indicators of longevity and lifetime productivity of cows depending on the level of inbreeding that outbred animals were the best.

The storage period of eggs has a negative influence on the incubation period, embryo development, egg hatchability and hatching of young animals, which ultimately reduces the economic efficiency of the poultry farm. In breeding quail farms, the collection period of hatching eggs can reach 2–3 weeks. Our studies have studied the infl uence of the storage period of hatching eggs on the duration and results of incubation, the development of young quails. These issues have been studied not enough in meat-productive quails. In Russia, similar studies have been conducted on egg-productive quails of Japanese gray breed. However, poultry with meat productivity differs in both the duration of incubation and its results due to differences in metabolism in the body. Research has been carried out at the Siberian Research Institute of Poultry Farming on the eggs of Radonezh quail breed. It has been established that storing quail eggs for more than 7 days reduced the capacity of egg hatchability by 3.3–29.0 abs.%, and the hatching of young animals by 6.2–36.5 abs.%. Extending the shelf life of quail eggs to 14–21 days increased the average incubation hour by 2.5–9.7 hours, had a statistically signifi cant infl uence during embryogenesis on the live weight of day-old quails, the use of nutrients in the yolk sac and the development of the heart, liver and muscular stomach. It is advisable to store the hatching eggs of meat-productive quails of Radonezh breed before incubation for no more than 7 days. The results of these research can be used in breeding, industrial and farm quail farms for planning the sampling time, the number of eggs laid for incubation and places for planting day-old young animals, the population of future layers, and the volumes of necessary feed.

Optimization of the amino acid balance of essential amino acids, as well as individual amino acids and probiotics, allows improving production indicators such as poultry livability, live weight gain, feed conversion and increasing the economic efficiency of meat production. The purpose of the research was to evaluate the eff ect of diff erent levels of arginine in poultry diets on average daily live weight gain and determine its effect on the livability of broiler chickens, optimize the amino acid composition of broiler chicken diets in accordance with the recommended standards of essential amino acids. The experiment was conducted at Kuratye LLC in Verkhniy Tagil in the Sverdlovsk region on the cross Arbor Acres of broiler chickens. The diet of the experimental group of broilers diff ered from the control diet in that the content of the amino acid arginine was brought to the standards recommended by German poultry farmers. It was found that the average daily live weight gain of broilers in the experimental group for the entire growing period was 47.7 g in the control group, in the experimental group it was 9.0 % higher than in the control and was 52.0 g. The European productivity index, calculated taking into account live weight, livability, fattening period of poultry and costs per unit of production in the control group was 274.0, and in the experimental group it was 309.2 units. From the conducted studies it follows that it is necessary to take into account the ratio of arginine to lysine in the diets of broiler chickens at the level of 1.04, 1.06 and 1.07, respectively, for the rearing phases such as starting, growth and finishing periods.

Highly productive animals experience energy deficiency at the beginning of lactation up to 30 % of their energy needs, since cows spend more energy on milk production than they intake with feed. Therefore, to maintain a high level of productivity and minimize live weight loss of cows, it is necessary to increase the energy supply of rations. For these purposes, along with the use of high-quality feed and a decrease in the proportion of starchy grain concentrates in the ration structure, various types of fats are used in feeding of cows, since their energy value is more than 2 times higher than proteins and carbohydrates. The purpose of the research was to study the eff ectiveness of using protected vegetable fats in feeding of highly productive lactating cows. Comprehensive studies were carried out to investigate the effectiveness of using new protected vegetable fats: hydrogenated (Ultra Feed F) and fractionated (Extra Feed F) in feeding of highly productive lactating cows and an assessment of the effectiveness of their use was given. It was recommended as a result of the research that in order to ensure milk productivity of cows at a level of more than 7000 kg of milk (7000–9000 kg), livestock farms should ensure the concentration of metabolic energy in the dry matter of the ration of at least 10.7 MJ/kg, with possible compensation for the deficit in the level of metabolic energy up to 11.0 MJ/kg with protected vegetable fats of domestic production (fractionated Extra Feed F and hydrogenated Ultra Feed F) in the amount of 300 g/head/day during the period of 21–120 days of lactation.

Artificial fish farming including commercial sturgeon farming using highly nutritious balanced feeds is nothing less than a strategically important area in Russian agriculture. In recent years, methods for increasing animal productivity using highly biologically active additives both natural and artifi cial, which have a growth-stimulating, protective and immune-modulating eff ect on the body of animals at various stages of development, have found wide application. These include the feed additive Abiotonic. In the literature studied by us, we found no information on the eff ect of the feed additive Abiotonic on the growth, development and livability of sturgeon fi sh, as well as on the quality indicators of the resulting fi sh products. In this regard, studies aimed at studying the eff ect of the vitamin-microelement growth immunostimulant Abiotonic on the productivity of sturgeon fi sh are relevant. The purpose of the research was to study the growth, development and commercial traits of sturgeon fi sh species under industrial fi sh farming conditions using the feed additive Abiotonic. The research established the optimal amount of the feed additive Abiotonic for use in the diets of the hybrid Russian and Siberian sturgeon inder industrial fi sh farming conditions. Thus, when rearing sturgeon fi sh with high productive and commercial traits, as well as with low feed costs per unit of fi sh weight gain and the cost of fi sh products under industrial conditions, we recommend that fish farms use the feed additive Abiotonic in the diets of sturgeon fi sh in the mount of 1.0 ml per 1.0 kg of fi sh body weight.

Oil fl ax is a valuable oil crop with a wide range of applications, the raw materials of which are used in the food, technical, chemical, pharmaceutical industries and feed production. In terms of metabolism energy content, fl ax seed surpasses the grain of legumes, cereals and oilseeds. Due to the combination of high energy nutritional value and a large content of useful organic elements, fl ax has a unique biological value. In terms of amino acid composition, fl ax seed is similar to soy protein, but it contains less lysine than soy. Flaxseed presscake obtained during oil production is the most valuable among other types of presscake. Adding waste from fl ax seeds to presscake and meal for young livestock is a proven and good preventive measure that allows reducing the use of expensive synthetic drugs. The purpose of the research was to study the possibility of increasing the productivity of oil fl ax in the Central Non-Black Earth region. Under the conditions of the Central part of the Non-Chernozem zone, on sod-podzolic heavy loamy soils, in multifactorial field experiments, comprehensive studies were carried out on the effect of various techniques (previous crop, use of microfertilizers, level of mineral nutrition, chemical measures of weed control) included in the cultivation technology to obtain diff erent levels of the planned yield of oil flax. It was found that for agricultural production it is possible to recommend the use of winter wheat in crop rotation as a predecessor for oil fl ax, application of mineral fertilizer at the rate of N175P20K65, calculated to obtain the planned yield of 2.5 t/ha, treatment of crops with a mixture of herbicides Hacker, VRG, 80 g/ha + Gerbitox, VRK, 0.8 l/ha, microfertilizer Micropolidoc Plus at a dose of 0.5 l/ha in the “herringbone” phase when the fl ax plants are 8–10 cm tall.

Published: November 2024

Introduction: Altered erythrocyte turnover may not adequately reflect the glycemic status in the glycated hemoglobin (HbA1c) levels. Hypothyroidism is one such condition that might cause reduced erythropoiesis and falsely high HbA1c values. The aim of the study is to evaluate the effect of thyroid hormone on HbA1c levels on non-diabetic hypothyroid individuals and also to evaluate HbA1c levels in hypothyroid individuals with diabetes and to compare them with normal healthy subjects. Methods: This prospective study was conducted on 210 individuals, of whom 70 were assigned to group I- hypothyroid individuals, 70 to group II- hypothyroid individuals with diabetes, and 70 to group III—Normal individuals. Following data regarding laboratory investigations were collected which included fasting blood sugar (FBS), postprandial blood sugar (PPBS), HbA1c, free triiodothyronine (fT3), free thyroxine (fT4), and thyroid stimulating hormone (TSH). Data analysis was performed using SPSS version 16.0. Results: The median level of HbA1c was significantly higher in hypothyroid than in normal individuals (5.6 [5.5-5.7] % vs 5.2 [5-5.3] %, P≤0.001). The median level of TSH was significantly higher in hypothyroid than in normal individuals (11.13 [6.9-22.9] μIU/mL vs 2.15 (1.33-1.60) μIU/mL). The serum level of HbA1c was significantly positively correlated with TSH in hypothyroid individuals (r=0.281, P≤0.01). Conclusion: There is a positive correlation between HbA1c and TSH, and a negative correlation between HbA1c and fT4 levels. Serum HbA1c levels were significantly higher in hypothyroid individuals than the normal individuals. Therefore, our study suggests that we should proceed with caution while interpreting HbA1c levels in individuals with hypothyroidism.

Published: November 2024

Beaches are vital for storm protection to coastal communities. The nearshore environment, subaerial beach, and dune system provide a first line of defense against hurricane impacts. Hurricane Ian made landfall in Lee County in 2022 and caused devastating damage to coastal communities, estimated at more than $112 billion U.S.. This study aims to create an integrated approach to analyze Hurricane Ian’s impacts on Estero Island, in Lee County, Florida, by examining changes in elevation, shore- line morphology, beach volume, and modeled channelization linked with estimated property damage to the households’ demographic and socio-economic characteristics. The modeled channelization resulting from receding flood waters and ebb surge is compared to impacts on the barrier island’s morphology and estimated damages. The study found that Estero Island sustained volume loss to the subaerial beach after Hurricane Ian with models indicating channelization of water across the barrier island and a greater number of buildings with increased damages were associated within 30 m of the modeled channels. Census data indicated that over 50% of the population on the island is 65 years of age and older, with the majority of households in income brackets below $100K, and approximately 17% living in poverty. The findings from this study present the importance of an integrated approach for extreme events for vulnerable populations, such as those on Estero Island, with a particular emphasis on addressing the needs of elderly residents, lower-income households, and structures built near modeled channels for future management efforts.

In this paper, 5-Dimethylamino-2-hydroxy-3-methoxy benzaldehyde sulfisoxazole (5DHMS) and Cu(5DHMS)2 compounds have been synthesized. The molecular structure characterizations were performed using experimental and computational methods. In the experimental part of the study, CHNS, FT-IR, NMR, TGA, and LC-MS analysis techniques were used. Density Functional Theory (DFT) was selected for the calculation level in the theoretical part. Firstly, optimized structures were obtained from the predicted 3D structures. Vibrational modes were calculated using the optimized structures of the compounds. The vibrational modes of each compound were analyzed in detail using potential energy distribution (PED). Molecular electrostatic potential and HOMO-LUMO maps were drawn. Global chemical reactivity descriptors of compounds were determined. Moreover, the effects of solvent media on chemical reactivity descriptors were revealed in detail. Protein-ligand interactions with the target receptor carbonic anhydrase II enzyme were performed. In addition, some essential biological activity parameters such as drug-likeness, toxicity, and ADME predictions were examined in silico.

Purpose. Demonstrate microcirculatory changes and justify the effectiveness of controlled hardware hypothermia in an experiment
Material and methods. To study microcirculatory changes during local instrumental hypothermia, everted cheek pouches of 20 hamsters were used. Local hardware hypothermia (LHH) was carried out using the ViThermo device in a mode with a target temperature of 18°C for 60 minutes. Optical coherence tomography (OCT) was performed for intravital monitoring of microcirculatory changes.
Results. At an interval of up to 5 min. There was an increase in vascular density to a value of 5.31% and a decrease to 4.76%. At the same time, the peak vascular system density (VSD) was reached at 3 minutes of LHH (5.31%). After 5 minutes of LHH application, and subsequently until 60 minutes, VSD decreased in steps from 0.1% to 0.02% per 1 minute per step. The lowest VSD was achieved at 57-60 minutes of VSD. The temperature of the outer surface of the golden hamster’s cheek pouch decreased slowly and gradually in increments of 1°C to 0.1°C in 1-10 minutes. After 60 minutes of LHH, the temperature of the golden hamster’s cheek pouch began to increase: at step 61 minutes, 19.80°C and 62 minutes, 21.40°C. VSD at 61-62 minutes stabilized to values of 3.62% and 4.43%, respectively.
Conclusions. The effect of LHH on the microvascular bed of the hamster buccal mucosa revealed a number of characteristic physiological changes. With a gradual decrease in tissue temperature, a slow decrease and then an increase in vascular VSD was detected on OKT scans. This substantiates the hypothesis that the use of “soft” tissue cooling in the form of PAH is more rational in relation to the microcirculation.

Published: November 2024

This study assessed food safety knowledge and practices (KP) among 461 university students in Jordan, comparing health-related and non-health-related students. A cross-sectional survey using a questionnaire evaluated demographics, food safety knowledge, and handling practices. Health-related students scored higher in food safety knowledge with significant differences between them (mean: 4.95 ± 2.32) compared to non-health-related students (mean: 3.73 ± 1.92, p < 0.001).
Health-related female students also demonstrated better knowledge (mean: 6.70 ± 1.95) than males (mean: 6.03 ± 2.38, p = 0.008). Significant differences were found, especially among non-health-related students.
Common issues included inadequate food storage knowledge and reliance on feel-touch tests instead of thermometers, leading to undercooking and foodborne infections. Additionally, the COVID-19 pandemic temporarily improved practices, though post-pandemic declines were noted in handwashing and thermometer use.
This study highlights the need for targeted interventions, particularly for male students not enrolled in health-related fields. Targeted educational programs and practical training focusing on food safety can significantly improve both knowledge and practice, reducing health risks. Including food safety modules in non-health disciplines can help bridge the gap between academic knowledge and practical application.

Authors: ردايده شهد , Ibrahim Mohammed
Published: November 2024

Polycystic Ovary Syndrome (PCOS) is a crucial infertility problem among women in the world; especially Arab women. The main objective of this case-control study was to perform anthropometric, biochemical, clinical and nutritional assessment among PCOS patients. The study population composed of 60 Jordanian women aged 19–39 years, and classified into two groups: 30 were cases (PCOS patients) and 30 were control group (Healthy women). Results of the study indicated that the Body Mass Index (BMI) were significantly higher among PCOS patients than healthy women. Furthermore, significant differences were shown in the mean values of Luteinizing Hormone (LH) and (LH): Follicle-Stimulating Hormone (FSH) (LH:FSH) ratio which were higher among PCOS patients with a p=0.01 and p=0.03, respectively. Also, significant differences between PCOS patients and healthy women were shown for three clinical manifestations of PCOS including infertility, sleep apnea, and eating disorders. Moreover, the findings of the validated food frequency questionnaire (FFQ) revealed no significant differences between two study groups in the consumption of macronutrients and total energy intake. It is obviously concluded from the study that PCOS is remarkably responsible for substantial variations in anthropometric and biochemical measurements, hormonal levels, and clinical features among PCOS patients.

Published: November 2024

Occupation health pertains to the health of employees in relation with their workplaces, and is aimed at the prevention of job-related injuries and illnesses. However, given the significance of occupational health and the possible adversarial effects of occupational hazards to the nursing team, there is paucity of evidence on the level of awareness, knowledge and attitudes of nurses towards occupational hazards in the workplace. The aim of this study is to measure levels of perceptions of occupational hazards, and to identify relationships and differences on perceptions of occupational hazards based on sociodemographic characteristics, the study employed cross-sectional, descriptive method. A valid and reliable 13-item questionnaire was used to measure perceptions of occupational hazards.
Results showed that nurses had high levels of perceptions of occupational hazards. Nurses with longer lengths of work experiences had higher levels of perceptions of occupational hazards than nurses with shorter lengths of work experiences..the study concluded that hospitals should implement strategies that can support nurses in sustaining high levels of perceptions of occupational hazards, and should find ways to retain nurses within the hospital workforce. Future research can examine personal- and organizational-level factors that can impede or facilitate perceptions of occupational hazards, and explore how perceptions of occupational hazards translate to actual injuries sustained at work, quality of workplace environment, quality of work life, job performance, patient satisfaction, and other relevant organizational and clinical outcomes.

Aim – modification of the method of quantitative determination of total flavonoids in the raw material of Polýgonum Aviculáre L., presented in State Pharmacopoeia, XIV Ed.
Material and methods. The raw material of knotgrass (grass) was harvested near the villages of Ponomarevka, Dombarovka, Alekseevka, Orenburg region in June and July, 2022. The harvested material was dried in accordance with the requirements of the SP. The quantitative content was studied using the Vilitek VBS ultrasonic bath at a temperature of 40°C and power of 60 W, the LAB-TB-6/W water bath at a temperature of 90°C, rotary evaporator "IR-1 LT" at a temperature of 70°C. The electronic spectra were measured on the UNICO 2800 UV spectrophotometer, in 10 mm thick cuvettes in the wavelength range from 190 to 700 nm. The comparison solution was prepared using 96% ethyl alcohol concentration.
Results. The presented method of quantitative determination can be used in "end-to-end" standardization, for raw material of other types of Polýgonum Aviculáre L., as well as medicinal herbal preparations based on Polýgonum AviculáreL. We selected the extraction conditions using 50% ethyl alcohol in the ratio (raw material-extractant) of 1:50 and boiling in the water bath for 60 minutes, which allowed us to achieve the yield of total flavonoids more than 0.5% as stated in SP XIV (FS.2.5.0069.18).
Conclusion. The new conditions for the analysis of the quantitative determination of the amount of flavonoids in the grass of the Polýgonum Aviculáre L. are proposed that are different from the ones stated in the pharmacopoeia. Main differences: single extraction vs. three-stage extraction described in the pharmacopoeia; reduction of extraction time in the water bath to 60 minutes, which is 30 minutes less than in the method of SP XIV; concentration of the extractant and the ratio of "raw materials to extractant". Thus, the method of quantitative determination of the grass of the Polýgonum Aviculáre L. has been modified in the terms of basic conditions of extraction of raw materials. Based on the data obtained, the average content of flavonoids in the raw material of Polýgonum Aviculáre L. was 1.8 ± 0.08%.

Aim – to determine the prevalence of preeclampsia and HELLP syndrome among patients hospitalized in surgical departments with complaints of pain in the epigastrium, right hypochondrium and/or nausea and vomiting.
Material and methods. An analysis was carried out of visits of pregnant women over 20 weeks to the surgical department in 2023 and 42 cases of hospitalization of pregnant patients with suspected acute surgical pathology hospitalized in surgical departments No. 6 and No. 7 of the Samara City Clinical Hospital No. 1 named after N.I. Pirogov. The following parameters were assessed: age, gestational age, complaints at the time of admission, general blood and urine test data, the condition of the fetus according to ultrasound, Doppler ultrasound, CTG, presence of obstetric and gynecological pathology and somatic diseases.
Results. Patients with acute appendicitis (7 out of 42 pregnant women) were excluded from the study. Of the remaining 35 patients, the diagnosis of severe preeclampsia, HELLP syndrome was made in 3 cases (8.6%), in 2 cases, gestational hypertension or protineria (5.7%) – the main group. Cholelithiasis, acute cholecystitis – in 2 cases (5.7%), in other cases the diagnosis of acute pancreatitis was made – 28 patients (80.0%). The work provides a comparison of clinical and laboratory parameters of patients in two groups, with obstetric and surgical pathology. A clinical case of a combination of severe PE with the development of HELLP-syndrome and cholecystitis is also presented.
Conclusions. Differential diagnosis between obstetric complications such as PE and HELLP-syndrome and acute surgical pathology still remains a pressing interdisciplinary problem. Severe forms of PE can take the form of acute pancreatitis, acute cholecystitis, or other diseases. According to the results of our observation, this phenomenon occurred in 15% of patients hospitalized in surgical departments. Only timely diagnosis allows choosing adequate routing and specialized care for this complication.

Fractures of the femoral neck hold a significant place in traumatology and orthopedics and represent a serious problem. Without surgical treatment, this pathology leads to complications and death of the patient within a year. Hip replacement is the choice of treatment method that allows the injured patient to be mobilized as early as possible. This promotes and has a positive effect on the timing and effectiveness of rehabilitation measures and minimizes the risk of developing possible complications.
The article demonstrates a successful experience of treating a patient with a fracture of the right femoral neck with displacement of fragments using the endoprosthetics method.
