The usage of a binder system for frozen berries in the manufacture of confectionery

The aim of the research was to create binding systems for confectionery using gelling agents. The possibility of using partially hydrolyzed liquid egg white (egg hydrolyzate) in the binding system of gelling agents (egg hydrolyzate - agar (EG-A), egg hydrolyzate - starch (EG-S)) was determined to obtain the required mechanical characteristics when creating coatings, ornaments or fillers in confectionery with whole berries or pieces of fruit. In this regard, a technology has been developed for the hydrolysis of liquid egg white in the presence of an acidic reagent. The best rheological characteristics of the gelling agent from egg white were obtained under the following hydrolysis conditions: egg white : 1% HCl ratio = 1:2, process temperature - 66°C, duration - 40 minutes, the pH of the egg hydrolyzate was 6.53, the amount of dry solids was 11.78%. The newly created systems with agar (E406, Germany), chemically modified food starch (E1442, Germany) and hydrolyzed egg white (egg hydrolyzate) allow to adjust the properties of the coating for quick-frozen berries used in semi-finished confectionaries or cakes. It is established that the coating for quick-frozen berries, which includes a system consisting of 1% E406 and 0.5% egg hydrolyzate, should be carried out in 2 stages. In the first stage, a 10-minute exposure of the coating, which has a tensile strength of 580 g cm-2 , allows to create a strong capsule around the berry, which prevents the processes of destruction from proceeding. The second stage is necessary to obtain a uniform surface coating of the semi-finished mix from the berries. In this case, the tensile strength of the coating should be 480 g cm-2 . The system created from the E1442 and egg hydrolyzate gelling agents was also used in 2 stages when making cakes, which were subsequently baked at 180 °C. The content of the binding system in the coating applied to the test substrate was 6.9–7.7%, the effective viscosity of the coating was 120–180 Pa s. The content of the binding system in the coating of the surface of the berries in the second stage was 5.2–6.3% with effective viscosity values of 50–90 Pa s. Semi-finished berry products and ready-made baked cakes, produced with developed binding systems, can be stored at -8 °C for 10 to 12 days. After refrigerated storage, the separated moisture was not observed in the test samples. The absence of the phenomenon of syneresis with the indicated proportions of the introduction of gelling agents in coating systems has been established

Последствия преконцептивного облучения родителей: эндокринно-обменная патология у потомков

Epidemiological studies of late effects of preconceptional (prior to conception) radiation exposure are necessary in order to understand the risks of tumor and non-tumor pathology in next generations. Research of possible relation between parental preconceptional exposure and development of endocrine and metabolic disorders in the offspring is one of the topical issues of radiation hygiene. The objective of the study: comparative analysis of endocrine and metabolic pathology in children of the individuals exposed to long term preconceptional external gamma-radiation at the Mayak Production Association – at the first atomic industry facility on Russia. Materials and methods: A retrospective research was performed based on the Ozyorsk Children’s Health Registry. Ozyorsk – the city where Mayak Production Association is the enterprise forming the city. Analysis of endocrine and metabolic disorders was performed for 13880 children of 1949-1973 years of birth who were born and resided in Ozyorsk; parents of 9321 children of this number had accumulated doses of prolonged external gamma-radiation exposure at the production facility prior to conception. A comparative analysis of the structure and incidence of “Endocrine, nutritional and metabolic diseases” and nosological forms of this class of pathology was performed. Characteristic features of parental preconceptional exposure were analyzed in relation to thyroid pathology in children. Relative risk of endocrine and metabolic disorders among the children of exposed and unexposed parents was calculated for the whole disease class and for certain nosologies. Results: A significant predominance of thyroid diseases, particularly, iodine deficiencies, was detected at an earlier age among the offspring of Mayak Production Association workers compared to the control group; these cases were mostly related to low dose parental preconceptional exposure. Thyroid cancer was further detected in 0.16% (15/9321) of the studied cohort of the offspring of exposed parents with average manifestation age of 42.6. Relative risk of thyroid diseases was significantly higher among the exposed parents’ offspring compared to the controls: 2.0 among boys (95% confidence interval 1.38-2.9), 1.59 among girls (1.25-2.02) and in the group as a whole – 1.64 (1.34- 2.01). Relative risk of thyroid diseases related to iodine deficiency among the offspring of Mayak Production Association personnel was almost twice higher than the in the control group: 1.92 (1.3-2.84) among boys, 1.68 (1.29-2.2) among girls, 1.7 (1.36-2.12) in the whole group. Discussion and conclusion: A statistically significant overweight of non-tumor thyroid pathology in the offspring of Mayak Production Association personnel cannot be explained through external reasons taking into account similar climate and geographic conditions, possible technogenic exposure and the same unified medical survey of the followed children. We cannot exclude increased sensibility if thyroid tissue to iodine deficiency and its predisposition to hypertrophy and hyperplasia among the offspring of individuals exposed to long term occupational contact with ionizing radiation sources; that should be taken into account in the course of medical monitoring of these patients. Further research of transgenerational effects in the offspring of personnel of radiation hazardous production facilities are needed for complete understanding of the role of parental occupational exposure in health risks for further generations.Эпидемиологические исследования отдаленных эффектов преконцептивного (до зачатия) радиационного воздействия необходимы для понимания рисков опухолевой и неопухолевой патологии у последующих поколений. Изучение возможной связи преконцептивного облучения родителей с формированием эндокринно-обменных нарушений у потомков является одним из актуальных аспектов радиационной гигиены. Цель работы: сравнительный анализ эндокринно-обменной патологии среди детей, чьи родители подверглись пролонгированному преконцептивному внешнему гамма-облучению на производственном объединении «Маяк» – первом в стране предприятии атомной отрасли. Материалы и методы: ретроспективное исследование выполнено на основе Регистра здоровья детского населения г. Озерска, градообразующим предприятием которого является производственное объединение «Маяк». Анализ эндокринно-обменных расстройств проведен среди 13 880 детей 1949–1973 гг.р., родившихся и проживавших в г. Озерск, из которых у 9321 ребенка родители до зачатия подверглись пролонгированному внешнему гамма-облучению на производстве. Проведен сравнительный анализ структуры и частоты класса «Болезни эндокринной системы, расстройства питания и нарушения обмена веществ» и его нозологических форм. Проанализированы особенности преконцептивного облучения родителей при детской тиреоидной патологии. Рассчитан относительный риск эндокринно-обменных нарушений среди детей экспонированных и неэкспонированных родителей в целом по классу и по нозологиям. Результаты исследования: среди потомков работников производственного объединения «Маяк» отмечено значимое преобладание болезней щитовидной железы и, в частности, йододефицитных состояний, которые диагностировались в более раннем возрасте, чем в контроле, и в большинстве случаев относились к преконцептивному облучению родителей в области малых доз. Рак щитовидной железы зарегистрирован в последующем у 0,16% (15/9321) исследуемой когорты потомков облученных родителей со средним возрастом манифестации 42,6 года. Относительный риск болезней щитовидной железы был значимо выше среди потомков экспонированных родителей по сравнению с контролем: среди мальчиков – 2,0 (95% доверительный интервал 1,38–2,9), среди девочек – 1,59 (1,25–2,02), в целом по группе – 1,64 (1,34–2,01). Относительный риск болезней щитовидной железы, связанных с йодной недостаточностью, среди потомков персонала производственного объединения «Маяк» почти вдвое превышал показатели в контроле: ОР 1,92 (ДИ 1,3–2,84) среди мальчиков, 1,68 (1,29–2,2) среди девочек, 1,7 (1,36–2,12) в целом по группе. Обсуждение и заключение: статистически значимое преобладание неопухолевой патологии щитовидной железы у потомков персонала производственного объединения «Маяк» нельзя объяснить внешними причинами, учитывая одинаковые климато-географические условия, возможное техногенное радиационное воздействие и единое медицинское обеспечение наблюдаемых детей. Повышенная восприимчивость тиреоидной ткани к дефициту йода и её предрасположенность к гипертрофии и гиперплазии среди потомков, чьи родители подверглись длительному профессиональному контакту с источниками ионизирующих излучений, не исключается, что важно учитывать при проведении медицинского мониторинга этих лиц. Дальнейшие исследования трансгенерационных эффектов у потомков персонала радиационно-опасных производств необходимы для полного понимания роли производственного облучения в риске для здоровья последующих поколений

Эффекты когнитивной реабилитации с применением двойной задачи у пациентов в раннем послеоперационном периоде прямой реваскуляризации миокарда

Aim. To assess the effects of cognitive rehabilitation with dual-task training that involves a cognitive task combined with postural and walking control, as well as electroencephalogram indices in patients in the early postoperative period after direct myocardial revascularization.Methods. The study enrolled 48 patients scheduled for coronary artery bypass graft surgery. Subjects in this prospective, randomized study were randomized using envelopes to a postoperative cognitive training group (n = 23) and non-training group (n = 25). The cognitive training was carried out daily, starting 3-4 days after the procedure and until the discharge order. Dual tasks training (a cognitive task combined with postural and walking control) lasted 15-20 minutes. All patients were submitted to an extended neurophysiological assessment (psychometric tests and electroencephalogram study) and stabilography 3-5 days before and 8-11 days after coronary artery bypass grafting.Results. The patients who underwent cognitive training experienced postoperative cognitive dysfunction (POCD) in 39% cases in the early postoperative period after intervention, while the non-training group - in 64%. The relative risk of developing POCD in the non-training group was 2.77 (95% CI: 0.86-8.91, Z = 1.704, p = 0.08). The patients in cognitive training exhibited better cognitive state compared to the preoperative state (Z = 2.58; p = 0.01) in the absence of statistically significant differences in the non-training group. Moreover, type-1 theta power values increased in the non-training group in comparison to the preoperative values, while the cognitive training group did not have a statistically significant difference in theta power.Conclusion. Positive effects of dual task rehabilitation on the neurophysiological parameters of patients undergoing direct myocardial revascularization were demonstrated. Positive effects include lower frequency of POCD, improved cognitive state and less pronounced cortical dysfunction. The dual task training had proved a suitable training method for this category of patients. Additional studies are required to test the possibility of increasing the duration and intensity of dual task training for stronger recovery effect and improved cognitive and walking performance of patients in the postoperative period after direct myocardial revascularization.Цель. Оценить влияние когнитивной реабилитации с применением двойной задачи на когнитивные, постуральные функции и показатели электроэнцефалограммы у пациентов в раннем послеоперационном периоде прямой реваскуляризации миокарда.Материалы и методы. В проспективном рандомизированном исследовании участвовали 48 пациентов, подвергнутых коронарному шунтированию. Путем простой рандомизации (метод конвертов) сформированы группы послеоперационного когнитивного тренинга (n = 23) и сравнения (n = 25). Основной группе когнитивный тренинг проводили ежедневно, с 3-4-го дня после операции и до выписки из стационара в виде 15-20-минутных сессий с выполнением двойных заданий (постуральный тренинг и когнитивная задача). Всем больным оценены нейрофизиологический статус (психометрическое тестирование и электроэнцефалографическое исследование) и стабилография за 3-5 дней до и на 8-11-е сут после вмешательства.Результаты. В раннем послеоперационном периоде кардиохирургических вмешательств у пациентов, прошедших когнитивный тренинг, число случаев послеоперационной когнитивной дисфункции (ПОКД) составило 39%, тогда как в группе сравнения - 64%. Относительный риск развития ПОКД в группе без когнитивного тренинга - 2,77 (95% доверительный интервал 0,86-8,91; Z = 1,704; p = 0,08). В группе когнитивного тренинга наблюдалось увеличение                интегрального показателя когнитивного статуса по сравнению с предоперационным уровнем (Z = 2,58; p = 0,01) при отсутствии статистически значимых различий в группе сравнения. Также обнаружено, что мощность биопотенциалов тета-1-ритма увеличилась по сравнению с дооперационными показателями только у больных группы сравнения, тогда как у участников, прошедших программу когнитивного тренинга, не выявлено статистически значимого послеоперационного увеличения тета-активности.Заключение. Показано положительное влияние когнитивной реабилитации с применением двойной задачи на нейрофизиологические показатели пациентов, перенесших прямую реваскуляризацию миокарда, в виде меньшей частоты ПОКД, улучшения когнитивного статуса и менее выраженной корковой дисфункции, что позволяет говорить об эффективности этого когнитивного тренинга для анализируемой выборки. Необходимо дополнительно рассмотреть вопросы продолжительности и интенсивности тренинга с использованием двойных задач для повышения восстановительного эффекта на интеллектуальные ресурсы и постуральные функции больных в послеоперационном периоде прямой реваскуляризации миокарда

An integrated pan-European research infrastructure for validating smart grid systems

A driving force for the realization of a sustainable energy supply in Europe is the integration of distributed, renewable energy resources. Due to their dynamic and stochastic generation behaviour, utilities and network operators are confronted with a more complex operation of the underlying distribution grids. Additionally, due to the higher flexibility on the consumer side through partly controllable loads, ongoing changes of regulatory rules, technology developments, and the liberalization of energy markets, the system’s operation needs adaptation. Sophisticated design approaches together with proper operational concepts and intelligent automation provide the basis to turn the existing power system into an intelligent entity, a so-called smart grid. While reaping the benefits that come along with those intelligent behaviours, it is expected that the system-level testing will play a significantly larger role in the development of future solutions and technologies. Proper validation approaches, concepts, and corresponding tools are partly missing until now. This paper addresses these issues by discussing the progress in the integrated Pan-European research infrastructure project ERIGrid where proper validation methods and tools are currently being developed for validating smart grid systems and solutions.This work is supported by the European Community’s Horizon 2020 Program (H2020/2014-2020) under project “ERIGrid” (Grant Agreement No. 654113).

Анализ распределения плотности источников тока (sLORETA) у пациентов после когнитивной реабилитации с применением двойной задачи в раннем послеоперационном периоде коронарного шунтирования

Highlights. For the first time, the method of standardized low resolution electromagnetic tomography – sLORETA was used to assess the neurophysiological correlates of the success of cognitive rehabilitation using dual task to recover the brain functions affected by ischemia during cardiac surgery.The patients who were successfully rehabilitated have demonstrated lower postoperative values of resting state theta activity within the right hemisphere, indicating the transfer effect, which is an important component of successful cognitive rehabilitation.Aim. Visualization and monitoring of brain ischemia is important for the diagnosis of cerebrovascular diseases. The aim of the study was to evaluate the possibilities and applicability of the method of standardized low resolution electromagnetic brain tomography – sLORETA for analyzing brain electrical activity in patients undergoing cognitive rehabilitation using dual tasks to recover impaired brain functions during ischemia associated with cardiac surgery.Methods. The study included 16 male patients (45–75 years old) who were admitted for planned coronary artery bypass grafting (CABG) to the Clinic at the Research Institute for Complex Issues of Cardiovascular Diseases. Clinical and neurophysiological examinations were performed 2–3 days before CABG and 1 week after surgery. All patients underwent cognitive rehabilitation that started at postoperative day 3 or 4 and lasted until discharge, the outcome was assessed as well. Monopolar EEG (62 channels) was recorded at rest in a sitting position with eyes closed in a light- and noise-insulated room using a Neuvo SynAmps2 Amplifier. Data processing of EEG background activity for sLORETA analysis was performed using the EEGLAB in MATLAB software (The MathWorks, Natick, MA, USA). The sLORETA algorithms were used to calculate dynamic cross spectrum and current source density within the analyzed frequency range (4–6 Hz). Statistical analysis of current source density indicators was carried out by using the method of statistical non-parametric mapping in the sLORETA software package, and the difference between the current source density in the pre- and postoperative period (after cognitive rehabilitation) was calculated as well.Results. Cognitive rehabilitation was successful in 44% (7 patients) of cases. The differences have been revealed between the groups with successful and unsuccessful cognitive rehabilitation by using sLORETA. The group with unsuccessful cognitive rehabilitation demonstrated higher current source density estimates in theta rhythm compared with the successful rehabilitation group, it was most pronounced (t>- 8.42; p<0.004) in the right hemisphere – Brodmann area 22, temporal lobe and superior temporal gyrus.Conclusion. The sLORETA method demonstrated the positive effect of cognitive training on changes in the spatial patterns of brain activity in patients undergoing onpump CABG. The successful cognitive rehabilitation was associated with lower postoperative resting state theta activity within the right hemisphere, indicating the transfer effect, which is an important component of successful cognitive rehabilitation.Основные положения. Впервые метод стандартизованной электромагнитной томографии низкого разрешения (sLORETA, standardized low resolution brain electromagnetic tomography) применен для оценки нейрофизиологических коррелятов успешности курса когнитивной реабилитации с использованием двойной задачи для восстановления функций мозга при ишемии, связанной с кардиохирургическим вмешательством.При успешно проведенной когнитивной реабилитации выявлены более низкие послеоперационные показатели мозговой активности покоя в низкочастотном тета-диапазоне, локализованные в структурах правого полушария, что может отражать эффект трансфера – важного компонента успешной когнитивной реабилитации.Цель. Визуализация и контроль ишемических изменений мозгового вещества важны для диагностики цереброваскулярных заболеваний. Целью работы явилась оценка возможностей и применимости метода стандартизованной электромагнитной томографии низкого разрешения (sLORETA) для анализа электрической активности головного мозга у пациентов, прошедших курс когнитивной реабилитации с использованием двойной задачи для восстановления функций мозга при ишемии, связанной с кардиохирургическим вмешательством.Материалы и методы. В исследовании включены 16 пациентов мужского пола (45–75 лет), которые поступили для планового коронарного шунтирования (КШ) в НИИ КПССЗ (Кемерово, Россия). Клинические и нейрофизиологические обследования проведены за 2–3 дня до и через неделю после вмешательства. Всем больным начиная с 3–4 суток послеоперационного периода и до выписки из стационара выполнен курс когнитивной реабилитации и оценена его успешность. Монополярную электроэнцефалограмму (ЭЭГ) в 62 стандартных отведениях регистрировали с помощью усилителя Neuvo SynAmps2 в состоянии покоя в положении сидя с закрытыми глазами в условиях свето- и шумоизолированной комнаты. Подготовка данных для количественного анализа фоновой ЭЭГ-активности методом sLORETA проведена с помощью программного обеспечения EEGLab и MATLAB. С использованием алгоритмов sLORETA рассчитаны динамический кросс-спектр и плотность источников тока в анализируемом частотном диапазоне (4–6 Гц). Статистический анализ показателей плотности источников тока проведен в пакете sLORETA с помощью метода статистического непараметрического картирования, рассчитан контраст плотности источников тока в до- и послеоперационном периоде.Результаты. Для 44% (n = 7) пациентов курс когнитивной реабилитации был успешен.  При рассмотрении показателей ЭЭГ-активности, полученных с помощью sLORETA, обнаружены различия между группами с успешной и неуспешной когнитивной реабилитацией. Высокая плотность источников тока тета-1-ритма в группе с неуспешной когнитивной реабилитацией по сравнению с группой с успешно завершенным тренингом была наиболее выражена (t>–8,42; p<0,004) в таких структурах правого полушария, как поле Бродмана 22, темпоральная доля и верхняя темпоральная извилина.Заключение. Метод sLORETA позволил продемонстрировать положительное влияние курса когнитивного тренинга на изменения пространственных паттернов мозговой активности у пациентов, перенесших КШ в условиях искусственного кровообращения. При успешно проведенной когнитивной реабилитации выявлены более низкие послеоперационные показатели осцилляторной мозговой активности покоя в низкочастотном тета-диапазоне, локализованные в правых темпоральных отделах коры. Эти результаты могут отражать эффект трансфера – важного компонента успешной когнитивной реабилитации

Factors associated with diversity, quantity and zoonotic potential of ectoparasites on urban mice and voles

Wild rodents are important hosts for tick larvae but co-infestations with other mites and insects are largely neglected. Small rodents were trapped at four study sites in Berlin, Germany, to quantify their ectoparasite diversity. Host-specific, spatial and temporal occurrence of ectoparasites was determined to assess their influence on direct and indirect zoonotic risk due to mice and voles in an urban agglomeration. Rodent-associated arthropods were diverse, including 63 species observed on six host species with an overall prevalence of 99%. The tick Ixodes ricinus was the most prevalent species, found on 56% of the rodents. The trapping location clearly affected the presence of different rodent species and, therefore, the occurrence of particular host-specific parasites. In Berlin, fewer temporary and periodic parasite species as well as non-parasitic species (fleas, chiggers and nidicolous Gamasina) were detected than reported from rural areas. In addition, abundance of parasites with low host-specificity (ticks, fleas and chiggers) apparently decreased with increasing landscape fragmentation associated with a gradient of urbanisation. In contrast, stationary ectoparasites, closely adapted to the rodent host, such as the fur mites Myobiidae and Listrophoridae, were most abundant at the two urban sites. A direct zoonotic risk of infection for people may only be posed by Nosopsyllus fasciatus fleas, which were prevalent even in the city centre. More importantly, peridomestic rodents clearly supported the life cycle of ticks in the city as hosts for their subadult stages. In addition to trapping location, season, host species, body condition and host sex, infestation with fleas, gamasid Laelapidae mites and prostigmatic Myobiidae mites were associated with significantly altered abundance of I. ricinus larvae on mice and voles. Whether this is caused by predation, grooming behaviour or interaction with the host immune system is unclear. The present study constitutes a basis to identify interactions and vector function of rodent-associated arthropods and their potential impact on zoonotic diseases

Comparative life cycle assessment of mini combined heat and power plants

The article presents the results of an environmental study of the mini combined heat and power plants (mini-CHPs) life cycle with gas engines operating on natural gas and biogas, and with diesel engines. The calculation of material and energy flows, the environmental impact on the atmospheric air, water basin and soil has been carried out. The largest mass of harmful substances in wastewater has been observed with the account of the life cycle assessment (LCA) for the mini-CHPs in biogas, the smallest mass in diesel mini-CHPs. During the operation of biogas, gas piston and diesel PI, significant greenhouse gas emissions have taken place because of the fuel combustion. The article considers the issues of thermal pollution in the environment. It has been revealed that the life cycle of the bioenergy installations has a maximum impact on the environment, with the account of the fuel combustion in mini-CHPs with diesel engines. Biogas mini-CHPs have a greater advantage considering the processes of the operation and fuel combustion. The conducted research can help in choosing the type of the engine when designing a mini-CHP

Environmental Component Economic Evaluation of the Renewable Energy Sources Life Cycle

Traditionally, renewable energy sources (RES) are considered the most environmentally friendly, but only the stage of their operation is evaluated. A method for the integrated assessment of the renewable energy environment sustainability has been proposed, taking into account their entire life cycle - from the extraction of natural resources for the production of a power plant to its utilization. An impact assessment of RES different types on the environment has been carried out in four areas: consumption of natural resources, pollution of water resources, pollution of the soil and pollution of the atmosphere. The comparison of the considered environmental components has been carried out on the basis of an environmental pollution economic assessment at the stages of the RES life cycle. Studies have shown that the life cycle of a solar power plant makes the greatest contribution to environmental pollution, but the mini-hydroelectric station - the smallest

Methodology for assessing the grain mass thermal effusivity in a metal silo under the influence of active ventilation

The purpose of studying the thermal effusivity of the grain mass in a metal silo is to obtain a dynamic mathematical model of the processes of layered changes in the temperature of the grain mass under the influence of an external factor. Such an external factor is the supply of cooling air through the air distribution grid of the bottom of the silo with the active ventilation of grain in a metal silo. The created mathematical and parametric models allow simulating the moisture transfer process using active air ventilation systems inside metal silos during storage of wheat grain. There have been developed some ways to improve the conditions for ensuring the quality preservation of grain during its long-term storage in a metal silo. It is necessary to load such a silo with grain completely, preferably up to the top, leaving free supergrannial space as small as possible. Another solution is thermal insulation of the surfaces of the silo. The task of ensuring the safety of wheat food grain can be accomplished not only on the basis of existing regulatory rules, but also by taking into account the results of new research. The main method of storage in metal containers, according to the instructions and safety regulations is the storage of grain in a dry and purified state. It is known that not only humidity and purity, but also the temperature of the grain put into storage affect the storage period

Sex characteristics of cognitive functions assessed by the MMSE and MoCA scores in patients with coronary artery disease

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
