The article concerns some specific features in the organisation of foreign language training for bachelors at non-linguistic higher school. Such organization includes classes involving experts from the real economy. There are advantages and disadvantages of such training interaction, which have been obtained in practice. Based on the analysis of methodological literature and empirical research, the following conclusion is made: interaction between students and external speakers during practical foreign language classes both motivates learning the language of specialization and expand the range of useful links. Moreover, it can improve bachelors’ meta-skills: presentation, analytical, auditory. Recommendations for creating more successful forms of professional pedagogical communication, including a triad of stakeholders (a guest lecturer, an academic and learners) are proposed.

THE AIM: a comprehensive assessment of the frequency, severity, and composition of cognitive impairments (CI) in patients with CKD stages 3A-5D, as well as to study the relationship between the levels of endothelial nitric oxide synthase (eNOS) and these impairments. PATIENTS AND METHODS: The study included 80 patients with CKD aged 26 to 79 years (mean age 58.9 ± 1.4 years), among them 43 women (mean age 60.1 ± 1.9 years) and 37 men (mean age 57.4 ± 2.3 years). All patients were divided into 2 groups: group 1 (pre-dialysis) included 40 patients (28 women and 12 men) with CKD 3A-5 (mean age 59.9 ± 2.1 years), group 2 (on dialysis) included 40 patients (18 women and 22 men) with CKD 5D (mean age 58.1 ± 2.1 years). Sarcopenia was verified according to the criteria of the European Working Group on Sarcopenia in Older People (EWGSOP). The presence and severity of CI were determined using the short mental status assessment scale (MMSE) and the Montreal cognitive assessment test (MoCA). To identify endothelial dysfunction, all patients underwent a test with endothelium-dependent vasodilation of the brachial artery, as well as determination of the level of eNOS (ELISA Kit, USA) in serum. RESULTS: The prevalence of sarcopenia in the 1st group was 12.5 %, and in the 2nd group, 42.5 %. The average age of patients with sarcopenia was 66.1 ± 2.1 years. The prevalence of CI according to the MoCA scale in the general cohort was 70 %, while in the 1st group – 67.5 %, in the second – 72.5 %, in the subgroup with sarcopenia – 76.2 %. CIs, determined by the MMSE scale, were on average in 67.5 % of the surveyed, and the quantitative prevalence in the groups was identical, however, the qualitative composition of CIs in the comparative analysis differed in the severity of manifestations. In a comparative assessment of the prevalence of CI (according to the MMSE scale) in patients with sarcopenia, it was found that this indicator was significantly higher than in the subgroup without sarcopenia and amounted to 90.5 % and 59.3 %, respectively. In patients with sarcopenia, the level of eNOS was lower than the mean values compared with the general sample, patients of the 1st group and the subgroup without sarcopenia (0.75 ± 0.1 ng / ml, 0.88 ± 0.1 ng / ml, 1 ± 0.1 ng / ml and 0.92 ± 0.2 ng / ml, respectively (p = 0.02)). According to the results of the test with endothelium-dependent vasodilation, the prevalence of endothelial dysfunction in the total cohort of patients was 48.8 % (in the 1st group – 27.5 %, and in the 2nd group – 70 % (p = 0.001)), in the subgroup of patients with sarcopenia – 57.1 %. CONCLUSION: A high prevalence of CI was found in patients with CKD. The progression of CKD is associated with the formation of endothelial dysfunction and the development of CI. The latter significantly impairs the quality and life expectancy of patients. The main mechanism of their development is increasing endothelial dysfunction, and eNOS plays a key role in this process. Sarcopenia is associated with an increased risk of CI, regardless of the studied population and the criteria for the diagnosis of sarcopenia, and plays an important prognostic value.

THE AIM: to study the clinical and pathogenetic features of the development of endothelial dysfunction (ED) in patients with chronic kidney disease stages 3A-5D and its contribution to the development of cognitive impairment.PATIENTS AND METHODS: The study included 80 patients with CKD stages 3A-5D aged from 26 to 79 years (average age 58.9 ± 1.4 years): 43 women (average age 60.1 ± 1.9 years) and 37 men (average age 57.4±2.3 years). The patients were divided into 2 groups: group 1 included 40 patients with CKD 3A-5 (average age 59.9 ± 2.1 years), group 2 included 40 patients with CKD 5D (average age 58.1 ± 2 years). All patients underwent common and biochemical blood tests, the levels of endothelial nitric oxide synthase 3 (eNOS-3) and endothelin-1 (END-1) were determined, an endothelium-dependent vasodilation test (EDVD) was performed, testing for the presence and severity of cognitive disorders using the Montreal Cognitive Assessment Scale (MoCA) and the Mini Mental State Examination (MMSE).RESULTS: The prevalence of ED in the overall cohort of patients based on the results of a positive test with EDVD was 55 % of cases. ED was statistically significantly more often detected in the group of patients receiving hemodialysis treatment compared to patients in group 1: 70 % versus 40 %, respectively (p=0.007). The level of eNOS-3 in group 1 was higher compared to group 2 and amounted to 1.01±0.5 ng/ml versus 0.76±0.3 ng/ml (p=0.008). While the level of END-1 was statistically significantly lower in patients of group 1 compared to group 2 and amounted to 45.4±9.1 pg/ml versus 54.9±4.7 pg/ml (p<0.001). Cognitive impairments were identified in the general cohort: according to MMSE – in 67.5 % of cases, according to MoCA – in 71.3 %, and were more common in group 2. There were no statistically significant relationships between the results of the EDVD test and testing on the MoCA and MMSE scales. The level of eNOS-3 was lower in the subgroup of patients with cognitive impairment according to MoCA compared to the subgroup without it: 0.73±0.1 ng/ ml versus 0.94±0.2 ng/ml (p=0.127). The content of END-1 was statistically significantly higher in the subgroup of patients with cognitive impairment according to MoCA – 52.98±1.2 pg/ml compared to the subgroup without it – 47.67±1.5 pg/ml (p=0.043). When assessing the relationship between the levels of eNOS-3 and END-1 and the results of the EDVD test, it was found that in patients with a positive test in group 1, the level of eNOS-3 was statistically significantly higher compared to group 2 (p=0.01). An inverse relationship was observed for END-1; its level was lower in patients of group 1 compared to group 2 (p<0.01).CONCLUSION. Thus, the study revealed a high prevalence of endothelial dysfunction in patients with CKD stages 3A-5D. Progressive loss of renal function leads to dysregulation of the molecular mechanisms controlling vascular tone and the development of ED. eNOS-3 and END-1 have demonstrated high sensitivity for ED verification, and their detection improves the quality of the EDVD test. The development and progression of ED in patients with CKD is a multifactorial process that leads to hemodynamic disturbances in various organs and tissues, their damage and has a negative impact on the patient’s quality of life, his cognitive status and life expectancy.
