    Aim. Oxidative stress plays a role in the pathogenesis of ureteral obstruction. Methods. We studied parameters of oxidative status, levels of advanced glycation end products (AGEs), and contralateral (CL) kidney function in the rat model of unilateral ureteral obstruction (UUO). The effect of Phlogenzym (12 mg/day orally); losartan (20 mg/l in drinking water), and their combination was studied. Results. In placebo-administered UUO rats AGEs and malondialdehyde levels were higher than in the sham operated controls. Function of the CL kidney was slightly impaired, its collagen content and protein/deoxyribonucleic acid ratio (P/DNA) in the glomeruli increased. All treatments prevented the rise in collagen content, P/DNA ratio, and improved CL kidney function. Phlogenzym ameliorated lipid peroxidation and AGE levels. Conclusions. In the model of UUO systemically increased oxidative stress may play a role in development of tubulointerstitial fibrosis and in the functional impairment of the CL kidney. Suppression of the oxidative stress and blockade of angiotensin-1 receptors might mitigate the progression of obstructive uropathy.ΠžΠΊΡΠΈΠ΄Π°Ρ‚ΠΈΠ²Π½ΠΈΠΉ стрСс Π²Ρ–Π΄Ρ–Π³Ρ€Π°Ρ” Π·Π½Π°Ρ‡Π½Ρƒ Ρ€ΠΎΠ»ΡŒ Ρƒ ΠΏΠ°Ρ‚ΠΎΠ³Π΅Π½Π΅Π·Ρ– обструкції сСчоводу.

    Carbon dioxide is a powerful physiological regulator (physiological and pharmacological pacemaker) of numerous body systems: cardiovascular, respiratory, nervous, excretory, hematopoietic, immune,etc. Therefore, at present, carboxytherapy, due to the universal nature of pharmacodynamics, its physiology is one of the methods widely used in medicine for the treatment of a large number of diseases and has received official recognition in many countries worldwide. The use of CO2 in surgery is not limited to disinfection of surgical wounds, wound healing, anti-inflammatory, hemostatic and antioxidant effects. Inhaling carbon dioxide in a low concentration (3-5%) has a reflex stimulating effect on the respiratory and vasomotor centers of the medulla oblongata: it causes deep and rapid breathing, and excitation of the vasomotor center - an increase in heart rate and blood pressure. This reflex effect of CO2 is used during anesthesia to stimulate pulmonary ventilation with a mixture of CO2 and O2 (carbogen) while suppressing pulmonary ventilation. Inhalation of CO2 helps with vascular collapse to increase cerebral blood flow. Thus, carboxytherapy in the complex of pharmacotherapeutic treatment of diseases is a worthy alternative to drugs that have synergistic pathogenetic (antioxidant, antihypoxic, anti-inflammatory) and symptomatic (vasodilator, analgesic, hypolipidemic, antiseptic, reparative) effects. Keywords: carbon dioxide, carboxytherapy, pathogenic therapy

    Aim. To assess the incidence of cerebrovascular events and cognitive status in the long-term period after coronary artery bypass grafting (CABG) in patients with and without preoperative mild cognitive impairment (MCI).Material and methods. This prospective study involved 115 patients aged 45 to 69 years, who were admitted to the hospital for elective on-pump CABG. All patients underwent clinical, laboratory, ultrasound, neuroimaging and neuropsychological examination 3-5 days before and 5-7 years after CABG. Cognitive functioning was assessed using screening neuropsychological scales and neuropsychological testing with an assessment of neurodynamics, attention and short-term memory. Pre-CABG MCI was diagnosed based on the criteria by R. Petersen et al. Therefore, the patients were divided into two groups: with (n=51) and without MCI (n=64).Results. It was found that strokes and dementia during the long-term postoperative period of CABG were observed only in the group of patients with preoperative MCI (7,84%). Five-seven years after CABG, a decrease in cognitive status according to neuropsychological scales was found in all patients (p≀0,05). A decrease in neurodynamics, attention and short-term memory compared to the preoperative level was found in 47,92% of patients with preoperative MCI, without MCI β€” in 40,63%. Neurodynamic disorders occurred equally frequently in both groups (63,8% and 57,8% of patients, respectively). Memory impairments were more often observed in patients with MCI (55,3%) compared to those without MCI (34,4%) (OR=2,36, 95% CI, 1,09-5,12, p=0,03). According to brain multislice computed tomography in the group with preoperative MCI, the number of patients with cysts and leukoaraiosis 5-7 years after CABG was higher than in those without MCI (p≀0,05).Conclusion. In the long-term (5-7 years) postoperative period of CABG, more than 40% of patients demonstrate a decrease in cognitive status, regardless of preoperative data. At the same time, preoperative MCI is associated with adverse cerebrovascular events and dementia, accompanied by morphological brain abnormalities. Due to the revealed facts, it is necessary to optimize approaches to drug treatment and secondary prevention of cognitive decline after cardiac surgery

    Aim. To evaluate the neuropsychological parameters from the main cognitive domains (neurodynamic functions, attention and short-term memory) and the brain electrical activity in patients with non-valve atrial fibrillation (AF).Methods. 21 patients with the mean age of 61 [56; 67] years with non-valve AF who were admitted to the Department of Interventional Diagnosis and Treatment at the Research Institute for Complex Issues of Cardiovascular Disease were included in the study. The control group consisted of 17 healthy individuals with the mean age of 55 [49; 62] years. All patients underwent neuropsychological screening and computerized testing of neurodynamic functions, attention and short-term memory along with electroencephalographic studies. Statistical analysis was performed using the STATISTICA 10.0 software package.Results. Mild cognitive impairment was observed in 43% of patients with non-valve AF accompanied by ischemic brain matter changes according to the findings of magnetic resonance imaging. Patients with AF had slower complex sensorimotor reaction, more errors, worse directed attention, memorization of words and meaningless syllables in comparison with healthy individuals. In addition, patients with AF and healthy subjects had differences in the fronto-occipital gradient of theta-2 rhythm. The worst neurodynamic parameters were associated with a greater power of theta rhythms predominantly in the posterior parts of the brain only in patients with AF.Conclusion. Patients with non-valve AF had cognitive deficit with impaired executive control, attention and short-term memory as well as the slowing of cortical electrical activity in comparison to healthy individuals. The data obtained in our study are beneficial for developing an individual approach to prevent the development and progression of cognitive impairment in patients with AF.ЦСль.

    HighlightsThe presence of preoperative mild cognitive impairment (MCI) in patients undergoing combined carotid endarterectomy and coronary artery bypass grafting is associated with an increased theta activity at the frontal and parieto-occipital regions of both hemispheres after surgery.Β AbstractAim. To study the impact of preoperative cognitive impairment on changes in electrical activity of the brain in patients undergoing combined carotid endarterectomy and coronary artery bypass grafting.Methods. Sixty-three patients undergoing combined carotid endarterectomy (CAE) and coronary artery bypass grafting (CABG) were included in the study. The patients were divided into three groups, depending on the preoperative cognitive functions: without cognitive impairment (n = 17), with MCI (n = 29), and with severe cognitive impairment (n = 17). High-resolution electroencephalography (EEG) (62 channels, bandpass filtered between 0.1–50.0 Hz, sampling rate of 1000 Hz) was performed 3–5 days before and 7–10 days after surgery.Results. Patients with severe cognitive impairment at baseline presented with higher theta activity at the frontal region of the left hemisphere compared to patients without cognitive impairment and patients with MCI (p = 0.048). At the same time, patients with MCI showed the most pronounced theta activity increase after surgery compared to preoperative levels at the frontal and parieto-occipital cortical regions of both the left and right hemispheres (p≀0.05). Postoperative changes of theta activity in patients with severe cognitive impairment were minimal and statistically insignificant.Conclusion. Patients without severe preoperative cognitive impairment presented with higher grade brain dysfunction in the form of increased theta activity at the frontal and parieto-occipital regions after combined CAE and CABG. A smaller decrease in theta power after surgery in patients with severe preoperative cognitive impairment, on the one hand, can indicate compensation after cerebral ischemia and resistance to hypoperfusion during on-pump cardiac surgery, and on the other, can be a manifestation of the ceiling effect and insufficiency of brain functional reserves.ΠžΡΠ½ΠΎΠ²Π½Ρ‹Π΅ полоТСнияНаличиС ΠΏΡ€Π΅Π΄ΠΎΠΏΠ΅Ρ€Π°Ρ†ΠΈΠΎΠ½Π½ΠΎΠ³ΠΎ ΡƒΠΌΠ΅Ρ€Π΅Π½Π½ΠΎΠ³ΠΎ ΠΊΠΎΠ³Π½ΠΈΡ‚ΠΈΠ²Π½ΠΎΠ³ΠΎ расстройства Ρƒ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ², ΠΏΠ΅Ρ€Π΅Π½Π΅ΡΡˆΠΈΡ… ΠΎΠ΄Π½ΠΎΠΌΠΎΠΌΠ΅Π½Ρ‚Π½ΠΎΠ΅ Π²ΠΌΠ΅ΡˆΠ°Ρ‚Π΅Π»ΡŒΡΡ‚Π²ΠΎ Π½Π° ΠΊΠ°Ρ€ΠΎΡ‚ΠΈΠ΄Π½Ρ‹Ρ… ΠΈ ΠΊΠΎΡ€ΠΎΠ½Π°Ρ€Π½Ρ‹Ρ… артСриях, ассоциировано с Π²Ρ‹Ρ€Π°ΠΆΠ΅Π½Π½Ρ‹ΠΌ послСопСрационным ΡƒΠ²Π΅Π»ΠΈΡ‡Π΅Π½ΠΈΠ΅ΠΌ Ρ‚Π΅Ρ‚Π°-активности Π²ΠΎ Ρ„Ρ€ΠΎΠ½Ρ‚Π°Π»ΡŒΠ½Ρ‹Ρ… ΠΈ ΠΏΠ°Ρ€ΠΈΠ΅Ρ‚ΠΎ-ΠΎΠΊΡ†ΠΈΠΏΠΈΡ‚Π°Π»ΡŒΠ½Ρ‹Ρ… ΠΎΡ‚Π΄Π΅Π»Π°Ρ… ΠΎΠ±ΠΎΠΈΡ… ΠΏΠΎΠ»ΡƒΡˆΠ°Ρ€ΠΈΠΉ. РСзюмСЦСль.

    Aim. To analyze structural chareacteristics and electroencephalographic (EEG) pattern of post-operation cognitive dysfunction (POCD) in patients after direct myocardial revascularization under artificial circulation (AI). Material and methods. Totally 114 male-patients included, underwent scheduled coronary bypass grafting (CBG) under the AI, with average age 55,9Β±5,3 y. In 3-5 days before operation and on 7-10 day after all patients underwent neurophysiological testing; of those 65 patients also underwent EEG. Results. The CBG operation with AI leads in 79% of cases to the early POCD. Cognitive impairment usually becomes prominent in the domains of neurodynamics and memory. It is shown that the early POCD is followed by EEG-signs of cortical dysfunction (increase of low-frequency theta-rhythm magnitude).Conclusion. According to the results of the study, in post-operative CBG with AI period the structure of POCD consists of injury of neurodynamics and memory, which might be a cause of decreased life quality of patients and efficacy of surgery itself

    TRAIT ANXIETY AS A RISK FACOR OF COGNITIVE DYSFUNCTION IN PATIENTS AFTER MYOCARDIAL REVASCULARIZATION

    Aim. To study the effects of trait anxiety (TA) on the post-CABG (coronary artery bypass graft surgery) dynamics of cognitive function in patients with coronary heart disease (CHD). Material and methods. In total, 52 patients, aged 45–70 years, were divided into two groups: with moderate (n=24) and high (n=28) levels of TA. Results. The patients with high TA demonstrated worse cognitive function parameters 6 months after CABG, compared to the patients with moderate TA levels. Conclusion. High TA levels are one of the factors which negatively affect cognitive function parameters in CHD patients. These patients could be regarded at increased risk of post-CABG cerebrovascular complications

    Aim. To study the sex characteristics of cognitive functions in a cohort of patients undergoing coronary artery bypass grafting (CABG) by comparing the results of Mini-mental state examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores.Material and methods. The prospective cohort study included 272 people, including 74 women aged 41 to 82 years, who were admitted to the Research Institute of Complex Issues of Cardiovascular Diseases for CABG surgery. All patients underwent clinical, laboratory, electrophysiological and ultrasound examinations. The Charlson comorbidity index (CCI) was calculated. Assessment of cognitive functions was carried out using the MMSE and MoCA scores. All types of statistical analysis were performed using the STATISTICA 10 program (StatSoft Inc., USA).Results. It was found that women scheduled for CABG have an older age and a higher CCI score compared to men (p=0,008). According to the MMSE, the likelihood of moderate and severe cognitive impairment in men compared with women was 1,36 times higher (odds ratio (OR), 1,35; 95% confidence interval (CI), 0,79-2,32, Z=1,11, p=0,27). The MoCA scores showed that half of the male (49%) and female (50%) participants had severe cognitive impairment. The likelihood of moderateand severe cognitive impairment in men compared with women was 1,33 times higher (OR, 1,33; 95% CI, 0,68-2,59, Z=0,841, p=0,40). According to subtests of the MoCA, men were better in naming (p=0,002), abstraction (p=0,005), and women outperformed men in verbal fluency (p=0,04). Regression analysis revealed that the most significant negative predictors for cognitive status as measured by the MMSE and MoCA scores for men and women were age and CCI.Conclusion. Women scheduled for CABG, having the worst clinical and demographic indicators, are comparable with men in cognitive status using the MMSE score. The MoCA score shows sex differences in naming, abstraction, and verbal fluency domains and revealed a higher percentage of severe cognitive disorders (up to 50%) compared to the MMSE score (7-9%). In male and female candidates for CABG, age and comorbidities are negatively associated with cognitive status
