    Mergers and acquisitions are a recognized and effective mechanism for the development of companies. Depending on the goals, mergers and acquisitions (M&A) can strengthen the organization’s market position, create new competitive advantages, enter new sales markets, acquire missing competencies, radically change key business parameters and improve the company’s structure. In Russia, the theoretical and methodological foundations of mergers and acquisitions are represented quite widely. Investigated the processes of mergers and acquisitions, examined the possible negative effects reflected in the decline in the value of the combined company. The development of business processes, primarily digital transformation, has a significant impact on the effectiveness of M&A. In 2016–2019 Among the 10 largest M&A transactions, both in the world and in Russia, information technology companies are regularly included. The paper considers one of the most relevant trends in the modern world - the digital transformation of the business, as well as the dependence on technologies and digital technologies, occurring not only in the IT company, but also in the non-technology sector company. The purpose of the research is to prove the direct relationship between digital transformation and M&A. In the course of the research, the following methods were used: analysis and synthesis, comparison, assessment and generalization of research results and reports of consulting companies. It is proved that digitalization is one of the most important reasons and drivers. The main recommendations for their implementation were formulated

    The level of natriuretic peptide is regarded as a prognostic predictor of postoperative heart failure in modern cardiac surgery, and moreover, this hormone is included in the standards of its early diagnosis around the world. This study was conducted at the Irkutsk Cardiac Surgery Center. The results of treatment of 78 patients were analyzed in order to determine the relationship between the dynamics of brain natriuretic peptides and the course of the early postoperative period in operations with artificial cardiopulmonary bypass. Patients were divided into three groups according to the level of natriuretic peptide elevation in the postoperative period. The study proved the dependence of the postoperative period on the multiplicity of the increase in the level of natriuretic peptide B-type.It was found that the higher the rate of increase in the hormone, the lower the numbers of the cardiac index in the postoperative period, longer duration of inotropic support (p > 0.05) and higher doses of adrenomimetics (p > 0.05). The duration of mechanical ventilation was also longer in the groups where a high level of natriuretic peptide was recorded (p > 0.05). Thus, the multiplicity of natriuretic peptide elevation can be a prognostic criterion for the postoperative period in cardiac patients. It is important to note that a single determination of the level of natriuretic peptide should not be used as a marker of postoperative heart failure and this study confirmed the necessity to monitor the dynamics of brain natriuretic peptide’s level in the perioperative period in patients operated with extracorporeal cardiopulmonary bypass

    Perioperative acute myocardial dysfunction is an actual problem of cardiac surgery. Rational use of inotropes and mechanical circulatory support in the postoperative period remains a subject of debate. The outcomes of the combined coronary artery bypass grafting and heart valve prosthesis were analyzed in Irkutsk Cardiac Surgery Center after 80 patients were operated on. As a result of the conducted research, authors proposed a method of differentiated approach to the treatment of acute heart failure in the early postoperative period. Failure to escalate therapy beta agonists in the absence of adequate response hemodynamics and the transition to a mechanical circulatory support improves performance of the cardiovascular system and clinical outcomes, reduces hospitalization duration in the department of intensive therapy. The study showed the superiority of an early beginning of an intra-aortic balloon counterpulsation before traditional inotropic therapy in the treatment of postcardiotomy heartfailure at combined cardiac surgery

    Since the end of 2014, the Russian economy has undergone major changes. The crisis continued until 2018, followed by stabilization and short-term growth in 2018-2019. The emerging positive trends were interrupted by the pandemic. All this has had a signifcant impact on the vocational professional eduation market, both in quantitative and structural terms. The modern world is changing too fast, it is necessary to form the creative potential of a person. The article states that specialists’ adaptation mechanisms to new conditions should change with the help of advanced training, obtaining new knowledge and skills in all forms of education, including the system of vocational professional education. This means that the market of educational services formed by state, departmental and corporate educational institutions must respond to the demands of the economy and consumers of these services. Such advanced technologies and methods as online studying should be used along with and in combination with ofine classes. The conducted research has shown that large corporations allocate signifcant funds for the training and retraining of specialists corresponding to the level of technological development, capable of making effective management decisions. The authors of the article note that in the system of vocational professional education consumers of educational services are most interested in training programs related to management, marketing, information and computer technologies, which is quite consistent with the digital economy and the knowledge econom

    Objective: to evaluate the efficiency of noninvasive supporting ventilation in patients with acute cardiorespiratory failure in the early postoperative period after cardiac surgery under extracorporeal circulation. Methods. Case histories of patients operated on the heart under extracorporeal circulation, who postoperatively developed acute car-diorespiratory failure requiring repeated artificial ventilation (AV), were retrospectively studied. According to the AV mode, the patients were divided into 2 groups. Non-invasive AV was carried out in Group 1 (a study group). In Group 2 (a control group), tracheal intubation and mechanical ventilation were performed when respiratory indices deteriorated. In both groups, anesthesia was maintained without deviating from the clinically accepted protocol. The indications for extubation were routine. Following 24—72 hours after extubation, the health status of patients became worse, as manifested in decreased circulatory performance, requiring that they be switched to AV. Clinical and laboratory findings were used to define indications for AV switching. The conditions for noninvasive ventilation were the close cooperation of a patient with medical personnel, the absence of significant hyperthermia, injury, operation or facial abnormally, which excluded intimate mating. Results. Analysis of gas exchange changes suggests that there are no differences between the groups both just after surgery and within 24 postperfusion hours after extubation. When the condition deteriorated, no differences in oxygen exchange and delivery were observed in the study and control groups. In the control group, PaO2, oxygenation index, and oxygen delivery index were significantly less than those in the study group. Analysis of the duration of assisted ventilation revealed that the study group patients were on a respirator significantly less than the controls. The length of intensive care unit stay also increased greatly in Group 2. All patients with normal gas exchange parameters were transferred to a specialized unit. Complications, such as insignificant skin damages at the site of intimate mask mating, were observed in the study group, while in the control group, ventilator-associated pneumonia was seen in 3 cases. Conclusion. The present study has provided evidence that noninvasive AV may be effective in the occurrence of acute cardiorespiratory failure requiring the correction of gas exchange parameters after surgery under extracorporeal circulation. Key words: noninvasive supporting ventilation, cardiosurgery, extracorporeal circulation.Цель исследования — оценить эффективность неинвазивной поддерживающей вентиляции при острой кардиорес-пираторной недостаточности в раннем послеоперационном периоде у пациентов после вмешательств на сердце с искусственным кровообращением. Методы. Проведено ретроспективное исследование историй болезни пациентов, оперированных на сердце с искусственным кровообращением, у которых в послеоперационном периоде возникла острая кардиореспираторная недостаточность, потребовавшая повторной ИВЛ. Пациенты, в зависимости от режима искусственной вентиляции, разделены на две группы. В первой группе (основной) искусственную вентиляцию легких проводили неинвазивным способом. Во второй группе (контрольной) при ухудшении дыхательных показателей проводили реинтубацию трахеи и механическую вентиляцию легких. Анестезиологическое пособие в обеих группах было проведено без отклонения от принятого в клинике протокола. Показания для экстубации были стандартными. Через 24—72 часа после экстубации у пациентов отмечалось ухудшение состояния, выразившееся в снижении производительности системы кровообращения, что потребовало перевода на ИВЛ. Использовали клинические и лабораторные данные для определения показаний к переводу на искусственную вентиляцию легких. Условиями проведения неинвазивной вентиляции были: полное содействие пациента с медперсоналом, отсутствие выраженной гипертермии, отсутствие травмы, операции или аномалии лица, которые исключают плотное прилегание. Результаты. Анализ изменений показателей газообмена говорит об отсутствии различий между группами как сразу после операции, так и после экстубации пациентов в течение 24 часов постперфузион-ного периода. На момент ухудшения состояния достоверных отличий по данным обмена и доставки кислорода в основной и контрольной группах не наблюдалось. Через 24 часа после начала повторной искусственной вентиляции легких и в последующие несколько суток зарегистрировано, что PaO2, индекс оксигенации и индекс доставки кислорода в группе контроля значимо ниже, чем в основной группе. При анализе длительности вспомогательной вентиляции выявлено, что пациенты основной группы находились на респираторе достоверно меньше, чем в группе контроля. Так же, во второй группе существенно увеличивалось и время пребывания в отделении реанимации. В профильное отделение все пациенты переводились с нормальными показателями газообмена. В основной группе наблюдались такие осложнения, как незначительные повреждения кожных покровов в местах плотного прилегания маски, а в контрольной, в трех случаях, вентилятор-ассоциированные пневмонии. Заключение. Настоящее исследование доказывает, что применение неинвазивной искусственной вентиляции легких может быть эффективно при возникновении острой кардиореспираторной недостаточности, требующей проведения коррекции показателей газообмена после операций с искусственным кровообращением. Ключевые слова: неинвазивная поддерживающая вентиляция, кардиохирургия, искусственное кровообращение
