Background — Magnetic resonance imaging (MRI) is a safe imaging technique that provides superior soft tissue contrast compared to other radiological imaging modalities. The main objective of this study was to measure awareness and knowledge of radiology students, interns, new graduates, and trainees regarding the safety of MRI. Material and Methods— To measure awareness and knowledge of the safety of MRI use, data was collected using a questionnaire from 166 subjects (age: 20-60 years) from August to September 2020 at Najran University and all hospitals and dispensaries in Najran region. Results — A total of 166 participants (45.2% male and 54.8% female) were included in the study. The participants were students (44%) from multiple levels (level 3-9), interns (17%), new graduates (19%), and trainees (20%). Our results showed that MRI is a safe method of evaluation and is superior to other tests in terms of safety and accuracy. Pregnant women can do the MRI scan after the end of the first 3 months. Conclusion — The MRI scan is safe but it has some risks that must be considered. There are different levels of knowledge and awareness regarding the safety of MRI use among the students, interns, fresh graduates, and trainees from all hospitals.

Rationale — The goal of the study was to investigate gender characteristics of functional somatic disorders in adolescents of the indigenous population of Khakassia (using the case study of the Abakan city). Material and methods — The object of the study was 215 (46.8%) boys and 244 (53.2%) girls of four secondary schools in Abakan. Their average age was 14.5±1.3 years. Data collection was conducted by means of an original screening questionnaire developed by Professor S.Yu. Tereshchenko. Results — The incidence of recurrent pain in the total sample of the surveyed youths was 184 (40.1%) for cephalalgia, 225 (49.0%) for abdominal pain, and 269 (58.7%) for back pain. The prevalence and structure of functional somatic disorders in Khakas adolescents depended on their gender. Asthenic syndrome was more common among girls – 42 (17.2%) vs. 14 (6.5%) in boys. In girls, the percentage of frequent headaches was higher than in boys: 22 (9.0%) vs. 8 (3.7%), respectively. Similar trend was observed in case of rare headaches: 100 (41.0%) vs. 54 (25.1%). Also, girls, compared with boys, were characterized by a higher incidence of both frequent and rare abdominal pains: 38 (15.6%) vs. 9 (4.2%) and 106 (43.4%) vs. 72 (33.5%), correspondingly. Conclusion — The case study of surveyed ethnic sample of Abakan school students revealed a high prevalence of recurrent pain syndromes in the indigenous youths of Khakassia. We have also established that incidence, structure and severity of recurrent pain, as well as its negative impact on well-being and daily activities, were associated with gender.

Mutations of the BRCA1/2 genes constitute a fundamental and independent risk factor in the genesis of both breast cancer and ovarian cancer. The specifics of the infertility treatment effect on the risk of developing cancer in carriers of mutations in the BRCA1/2 genes remain unclear and require a comprehensive investigation. In this review, we analyzed published sources on the possible relationship between the infertility treatment and the risk of ovarian and breast cancer in BRCA1/2 mutation carriers.

Objective — To compare the expression of the LC3B autophagy marker before and after treatment with high-intensity focused ultrasound therapy (HIFU) and combined therapies: androgenic deprivation AD + HIFU, AD + radiation therapy in patients with and without recurrent prostate adenocarcinoma. Material and Methods — The objects of our study were biopsy specimens of prostates obtained from 70 patients with prostate adenocarcinoma before and after treatment. The first group consisted of patients without signs of relapse after treatment, as evidenced by a normal blood PSA level, the results of ultrasound procedure and biopsy. The second group included patients who had a recurrence of adenocarcinoma after treatment. Patients received the following cancer treatments: ultrasound ablation (HIFU), combination therapy: androgenic deprivation AD + HIFU, AD + radiation therapy. An immunohistochemical staining in two groups was performed with an anti-LC3B antibody. Results — In the group of patients without relapse, the expression of the autophagy marker sharply decreased in the tumor tissue after treatment, but it increased in the stroma of muscle connective tissue and the vascular wall. In the group of patients with relapse, the expression of anti-LC3B antibody significantly increased in tumor cells, in stroma of muscle connective tissue, and in vascular wall after treatment. In both groups, the magnitude of the autophagy marker expression did not depend on the treatment method. Conclusion — The autophagy is one of the factors contributing to the survival of prostate adenocarcinoma cells after treatment; the increase in autophagic protein expression after treatment in patients with prostate adenocarcinoma can be used to assess the risk of relapse.
目的-比较复发性前列腺癌患者在接受高强度聚焦超声治疗(HIFU)和雄激素剥夺AD + HIFU、AD +放疗联合治疗前后LC3B自噬标志物的表达。材料和方法:我们研究的对象是70例前列腺腺癌患者治疗前后的前列腺活检标本。第一组由治疗后无复发迹象的患者组成，通过正常的血液PSA水平，超声检查和活检结果证明。第二组包括治疗后腺癌复发的患者。患者接受以下癌症治疗:超声消融术(HIFU)，联合治疗:雄激素剥夺AD + HIFU, AD +放疗。两组均采用抗lc3b抗体进行免疫组化染色。结果-在无复发组，治疗后肿瘤组织中自噬标志物的表达急剧下降，而在肌肉结缔组织间质和血管壁中表达升高。复发组治疗后肿瘤细胞、肌肉结缔组织间质、血管壁中抗lc3b抗体表达明显升高。在两组中，自噬标志物的表达量不依赖于治疗方法。结论-自噬是前列腺腺癌细胞治疗后存活的因素之一;前列腺癌患者治疗后自噬蛋白表达的升高可用于评估复发风险。

Introduction — High mortality and morbidity rate of empyema, despite effective antibiotic therapy, highlights the need to determine the optimal drainage method as a first-line surgical intervention. Controversies behind the treatment choice for empyema encouraged us to conduct this study aimed at demonstrating efficacy and differences of two techniques of clinical approach to empyema, chest tube and video-assisted thoracoscopic surgery (VATS) with respect to outcomes. Material and Methods — We recruited 60 eligible patients with empyema and distributed them among two groups according to applied treatment strategies, either chest tube treatment method (Group I, 30 subjects) or VATS (Group II, 30 patients). Data were statistically analyzed by SPSS software, version 19. Then, the one-sample Kolmogorov–Smirnov test confirmed the normality of data distribution, and independent samples t-test was performed. Statistical significance was assumed at p<0.05. Results — We established that the length of hospital stay (p=0.002), the need for second intervention (p<0.001), and rate of recurrence (readmission) (p=0.001) were significantly lower in patients treated with VATS, compared with patients who were subjected to chest tube drainage. Additionally, patients who underwent VATS exhibited higher satisfaction level (p=0.03) and improved clinical condition at the time of discharge (discharged without chest tube) (p<0.001), than those from Group I. Radiographic examination on postoperative day 7 revealed a higher rate of complete cure (normal lung expansion) in the VATS group (p=0.004). Conclusion — According to the results of our study, VATS is a better treatment technique of empyema, compared with chest tube.

Objective — To evaluate the effect of the frequency of retinoprotective therapy courses on perimetry parameters, to compare Octopus 900 perimeter with Octopus 600 perimeter, and to assess threshold perimetry results of G-dynamic versus 24-2 programs. Material and Methods — The study involved 17 patients (34 eyes) diagnosed with primary open-angle glaucoma of advanced stage. Group 1 included subjects receiving a course of Retinalamin every 3 months. Group 2 comprised patients undergoing Retinalamin therapeutics every 6 months. Results — At the onset of the study via G-dynamic and 24-2 programs, we did not observe any statistically significant differences between the groups in mean deviation of retinal photosensitivity (MD) and pattern standard deviation of mean retinal photosensitivity (PSD). However, the absolute values differed between groups and between programs. On average, the differences in MD and PSD values obtained in the photosensitivity study with G-dynamic vs. 24-2 programs were -0.36 dB (CI 95%: -4.27; 3.54) and 0.63 dB (CI 95%: 2.37; -1.11), respectively. Hence, studies performed via 24-2 and G-dynamic programs yielded comparable results (no statistically significant differences). However, they could not be identical due to different spatial arrangement of points in different programs. Conclusion — As a result of conducted treatment, retinal photosensitivity did not exhibit statistically significant changes; however, we observed positive dynamics in both groups in MD and PSD parameters of mean retinal photosensitivity. Different devices (Octopus 600 and Octopus 900 perimeters) and different programs (24-2, G-dynamic) yielded different outcomes due to their technical features and capabilities of reproducibility; however, these differences were not statistically significant.

Obesity is a non-infectious pandemic. The visceral distribution of adipose tissue is a significant factor in the development of cardiovascular diseases and their complications. Along with the visceral abdominal depot in omentum and subcutaneous tissue, there are other ectopic adipose tissue depots: epicardial adipose tissue (EAT), perivascular adipose tissue (PVAT) and perirenal adipose tissue. This article presents a review of the physiological role and molecular basis of the PVAT and EAT function in healthy, as well as in pathological, conditions; the interaction of adipokines and cytokines, their contribution to the development and progression of cardiovascular diseases. The review discusses well-known facts and controversial issues in this field. Comprehensive investigation of the mechanisms of vascular and myocardial pathology in obese people, along with identification of biomarkers for early prediction of cardiovascular complications, would contribute to the development of targeted preventive measures and choice of therapeutic strategies, which is consistent with the contemporary concept of personalized medicine. We have analyzed domestic and foreign literature sources in eLIBRARY and PubMed scientific libraries for the period of 2001-2020.

Objective – Our study aimed at evaluating changes in liver tissues after simulated injury and use of novel hemostatic agents (containing tranexamic acid) in the course of in vivo experiment. Material and Methods – The following hemostatic agents were studies: TachoComb collagen plate (Group 1); samples of novel local hemostatic agents based on sodium carboxymethyl cellulose (CMC), Na-CMC (Group 2); Na-CMC + tranexamic acid (Group 3). We performed the study on 30 rabbits with simulated liver laceration via laparoscopy, and were stopping bleeding by means of the above-mentioned methods. Then, on liver tissue micrographs, we were measuring capsule thickness (μm), sizes of hepatocytes and their nuclei (px), number of binuclear hepatocytes. We were also calculating nuclear-cytoplasmic ratio (NCR) of hepatocytes, as well as identifying qualitative and quantitative capsule composition in tested samples. Results – In the collagen plate group, the capsule width was 3.2-fold and 3.6-fold of this parameter in samples from Groups 2 and 3. Indirectly, this finding implied more severe inflammatory and regenerative processes aimed at limiting injury area, and was confirmed by statistically significant differences in the cellular composition of the capsule surrounding tested samples (fibroblastic cells predominated in Groups 2 and 3, and there were fewer of them in Group 1). The highest cell index (CI) value was detected in Group 3. Conclusion – A significant boundary zone separating tested materials from the liver parenchyma was also observed due to connective tissue growth as part of inflammatory response.

Objective — To examine the morphometric parameters of neurons and the oxidative status of the Wistar rat brain tissues after administering proline-containing peptides, also known as glyprolines (Arg-Gly-Arg-Pro-Gly-Pro [RGRPGP] and Thr-Lys-Pro-Arg-Pro-Gly-Pro [WKPRPGP; Selank]), on a traumatic brain injury (TBI) model. Study subjects — Our study involved 26 mature male Wistar rats (2.5-3 mos. old, 220-300 g). The morphometric parameters of neurons and the oxidative status of animal brain tissues were studied. Material and Methods — Four experimental groups were formed. Group 1 included intact control animals. Animals in three other groups were subjected to TBI via free fall of a 50 g weight from a height of 50 cm on the second day of the experiment and received the following injections: 0.9% sodium chloride solution in Group 2; WKPRPGP peptide solution in Group 3; RGRPGP peptide solution in Group 4. Substances were administered intraperitoneally on a daily basis at a dose of 0.1 mg/kg from day 1 through day 5 of the experiment. Morphometric parameters of rat brain neurons were studied on paraffin sections stained with hematoxylin and eosin. The intensity of free radical processes in the brain tissue was investigated by chemiluminescence. Results — An analysis of morphometric parameters revealed significant increases in the neuronal cytoplasm area, nucleolar area, number of nucleoli, and nuclear-nucleolar index with the introduction of the RGRPGP peptide after TBI, compared with the WKPRPGP peptide under the same conditions. After TBI and peptide administration, we observed an oxidative stress in the neocortex of Wistar rats, and it was more pronounced in the group of animals treated with RGRPGP. Conclusion — After RGRPGP peptide administration, we observed an increase in the morphometric parameters of neurons in the closed TBI model: a larger area and a greater number of nucleoli. Chemiluminescence data implied that WKPRRPGP peptide better protected brain tissue in rats from the effects of oxidative stress caused by TBI.
