The purposeof the article is to present the author’s approach to the study of information management when making managerial decisions by public administration bodies. In this paper, information management is consistently considered as an object, subject and method of information management. By the example of the content and correlation of such concepts as data and information, information and knowledge, the main obstacles to the transition of the state from the information economy to the digital economy are shown. The hypothesis is formulated that effective information management does not so much contribute to the formation of the added value of management processes, as it creates the potential for obtaining additional value of a management decision as an information product.Materials and methods. The research is based on the analysis of the processes of informatization of society and the state, as well as the analysis of the possibilities of information management for building a digital infrastructure and effective interaction of the subjects of the digital economy. Various aspects of information management are disclosed in accordance with the “subject-object-subject” and “subject-object-object” models. The problems of determining the quantity and quality of information are revealed in comparison with the attributive, functional-cybernetic and semiotic concepts of information. The information base of the research was made up of the results of scientific research in the field of decision-making in public administration and methodological approaches to information management used in science.Results. The main risks and problems of information management in decision-making by public administration bodies were identified. It is determined that knowledge becomes an economic resource not at the stage of its production, but at the stage of use. This resource allows you to create the added value of a management solution as an information product. It is proved that the role of the state in the dissemination and use of knowledge is provided by the unconditional desire of the individual to produce new knowledge. In addition, it is shown that for the transition to the digital economy, the state needs to create an information infrastructure in which openness and transparency of data are combined with equal opportunities for individuals in the economy (inclusive economy).Conclusion.Information management is a significant factor in the transition of the state from an information economy to the digital one. The simple accumulation of information and knowledge cannot be a guide for the transition to the digital economy. Information management from the perspective of creating and using additional information value will avoid the risk of mechanical informatization and uncontrolled digitalization. The state activities in this direction should be responsible and consistent. The volume of information increases as a result of the individual’s desire to produce new knowledge, but the social value of knowledge increases as a result of the effective impact of the state on the development of information infrastructure and the diffusion of information technologies. Thus, the realization of the potential of the additional value of information and its scaling on the basis of state-supported platform tools will allow for the transition from the information economy to the digital economy.

Aim. To determine prevalence of glaucoma among adult urban population on example of Ganja city of the Azerbaijan Republic.Methods. In city polyclinics primary examination was performed in 6585 people that makes 3% of adults of the population. Among the examined patients the indications for thorough in-patient work-up were determined in 250 patients. The diagnosis of glaucoma was confirmed in 220 patients (90 males and 130 females). The prevalence of glaucoma was determined (in % of the examined patients). The patients were divided into groups according to their gender, age, education, family history, presence of eye and internal diseases. A group with the lowest prevalence of glaucoma was chosen as a reference, and the other groups were termed as study groups for the assessment of relative risk of glaucoma development.Results. Glaucoma was revealed in 2.7±0.28% of males and 3.9±0.34% of females (p 0.05). Morbidity rate in women is higher compared to men. Risk factors of glaucoma are: intraocular pressure 21 mm Hg - 3.8±0.24%, compromised family history - 4.7±0.27%, diabetes mellitus - 3.66±0.24%, myopia - 5.7±0.3%, cataract - 10.0±0.4%, arterial hypertension - 11.9±0.4%. General morbidity rate of glaucoma among patients older than 20 years old is 3.45±0.23%. The lowest prevalence of glaucoma was determined among people of 20-29 years old (0.9±0.22%; 95% confidence interval 0.40-1.33). Prevalence of glaucoma increases with age of the examined patients. Statistically significant increase of prevalence of glaucoma is detected among population aged 40 years or older (3.3±0.49% of people aged 40-49 years) and reaches its maximum among people aged 60-69 years (12.2±1.56%).Conclusion. Prevalence of glaucoma among population of Ganja aged 20 years and older is comparatively high; differentiated monitoring of intraocular pressure with risk factors taken into account is reliable for early detection of glaucoma.

Occlusion of the superficial femoral artery is a frequently encountered pathology in peripheral vascular disease. In patients with chronic lower limb ischaemia in a lesion of crural arteries the results of femoropopliteal bypass grafting are unsatisfactory, therefore, the deep femoral artery becomes the decisive collateral pathway for perfusion of the lower extremity.The study included a total of 166 patients presenting with TASC II B, C and D type lesions of the femoropopliteal segment after profundoplasty, who were subdivided into 3 groups depending on the stage of chronic lower limb ischaemia: Group 1 - 95 patients with stage II B, Group 2 - 56 patients with stage III, and Group 3 - 15 patients with stage IV.Five years after profundoplasty in Group 1 amputation was avoided in 90 patients (94.7%) in Group 2 - in 47 patients (83.9%), where p=0.028. During 14 months in Group 3 due to unsatisfactory distal bed 15 patients (100%) were subjected to amputation of the operated lower limb at various levels. The binary logistic regression analysis of the diameter of the deep femoral artery (p=0.045, OR=0.139) and the state of the distal arterial bed (p=0.02, OR=9.341) demonstrated that the diameter of the artery directly influenced the outcome of profundoplasty within up to 5 years.Profundoplasty is an effective operation from the point of view of clinical and haemodynamic outcomes for patients presenting with occlusion of the superficial femoral artery and stenosis of the deep femoral artery with stage IIB and III chronic lower limb ischaemia. The diameter of the deep femoral artery and the condition of the arterial bed are the factors influencing the results of profundoplasty within up to 5 years.Окклюзия поверхностной бедренной артерии – это частая патология при заболеваниях периферических сосудов. У больных с хронической ишемией нижних конечностей при поражении артерий голени отдаленные результаты бедренно-подколенного шунтирования являются неудовлетворительными, поэтому глубокая бедренная артерия становится решающим коллатеральным путем для перфузии нижней конечности. Материалы и методы. В исследование включены 166 больных с поражением бедренно-подколенного сегмента TASC II B, C и D типов после выполнения профундопластики, которые были разделены на 3 группы в зависимости от стадии хронической ишемии нижних конечностей: 1 группа – 95 пациентов со IIБ стадией, 2 группа – 56 пациентов с III стадией, 3 группа – 15 пациентов с IV стадией. Результаты. Через 5 лет после профундопластики в 1 группе ампутации удалось избежать у 90 пациентов (94,7%), во 2 группе – у 47 пациентов (83,9%), где p=0,028. В течение 14 месяцев в 3 группе вследствие неудовлетворительного дистального русла у 15 пациентов (100%) была выполнена ампутация оперированной нижней конечности на разных уровнях. При бинарном логистическом регрессионном анализе диаметра глубокой бедренной артерии (p=0,045, OR=0,139) и состояния дистального артериального русла (р=0,02, OR=9,341) выяснилось, что диаметр артерии напрямую влияет на исход профундопластики в сроке до 5 лет. Заключение. Профундопластика – это эффективная операция с точки зрения клинических и гемодинамических результатов для пациентов с окклюзией поверхностной бедренной артерии и стенозом глубокой бедренной артерии с хронической ишемией нижних конечностей IIБ и III стадий. Диаметр глубокой бедренной артерии и состояние дистального артериального русла являются факторами, влияющими на результат профундопластики в сроке до 5 лет.

Our study was aimed at determining advantages of profundoplasty in patients with critical ischaemia of lower limbs in repeat arterial reconstructions. It included a total of 56 patients subjected to redo operations for thrombosis of a femoropopliteal bypass graft. Of these, 29 underwent profundoplasty (group I) and 27 repeat femoropopliteal bypass grafting (group II). Critical ischaemia was relieved in the early postoperative period in 28 (97%) and 24 (89%) patients of group I and II, respectively. The 3-year patency rate after profundoplasty amounted to 100% and after femoropopliteal bypass grafting to 47% (p0.05). The lower-limb amputation rates over the 3-year period of follow up amounted to 3 (10%) and 11 (41%), p0.05, respectively. Over the 3-year period of follow up, there was no statistically significant difference in the values of the ankle-brachial index (p0.05).В работе определены преимущества профундопластики у пациентов с критической ишемией нижних конечностей при повторных артериальных реконструкциях. В исследование были включены 56 пациентов, которым повторно выполнялась операция по поводу тромбоза бедренно-подколенного шунта: 29 проведена профундопластика (I группа), 27 – повторное бедренно-подколенное шунтирование (II группа). Купирование критической ишемии в раннем послеоперационном периоде отмечено у 28 (97%) больных I группы и 24 (89%) – II группы. Показатель проходимости за 3-летний период наблюдения после профундопластики составил 100%, после бедренно-подколенного шунтирования – 47% (р0,05). Ампутация нижней конечности за 3-летний период наблюдения в I группе осуществлена 3 больным (10%), во II группе – 11 (41%), р0,05. За 3-летний период наблюдения в группах не было статистически значимой разницы в показателях лодыжечно-плечевого индекса (р0,05).

Atherosclerosis obliterans is managed by various reconstructions of lower-limb arteries, but despite this, in the immediate and remote postoperative period there appears the necessity to carry out repeat reconstructions, which might be caused by shunt thrombosis, progression of atherosclerosis, etc. One of the methods of solving this problem is revascularization of lower-limb arteries through the deep femoral vein with plasty thereof. In occlusive lesions of the superficial femoral artery, the deep femoral artery plays the key role in blood supply of the entire extremity. The article deals with the principles of repeat surgical treatment of lower-limb arteries with the use of the deep femoral artery, also discussing the problems concerning the frequency of occurrence of thromboses in various positions, and the role of the deep femoral artery in blood supply of the lower extremity. The problem of efficacy of redo operations on lower-limb arteries using the deep femoral artery is still important. Despite the possibility of revascularization of lower extremities through the deep femoral vein, a high percentage of amputations remains. The terms of patency of the reconstructed deep femoral artery has proved to be several times longer than those of femoropopliteal and femorotibial shunts in the remote postoperative period. Besides, there are no clear-cut criteria for prognosis of efficacy of reconstructive interventions on the deep femoral artery in patients with multi-segment lesions of arteries of lower extremities after primary interventions, therefore, no common surgical policy exists. The use of the deep femoral artery in patients with ischaemia of lower extremities is explained by the minimally traumatic nature and confirmed efficacy after a series of previously performed multilevel operations, severe lesions of the distal bed, as well as in patients with severe concomitant diseases.При облитерирующем атеросклерозе осуществляются различные реконструкции на артериях нижних конечностей, но, несмотря на это в ближайшем и отдаленном послеоперационном периоде возникает необходимость в проведении повторных реконструкций, причинами которых могут быть тромбозы шунтов, прогрессирование атеросклероза и т. д. Одним из способов решения данной проблемы является реваскуляризация артерий нижних конечностей через глубокую артерию бедра с ее пластикой. При окклюзионном поражении поверхностной бедренной артерии глубокая бедренная артерия имеет колоссальное значение для кровоснабжения всей нижней конечности. В статье освещаются принципы повторного хирургического лечения артерий нижних конечностей с использованием глубокой артерии бедра, обсуждаются вопросы частоты возникновения тромбозов в различных позициях и роль глубокой артерии бедра в кровоснабжении нижней конечности. Проблема повышения эффективности повторных операций на артериях нижних конечностей с использованием глубокой бедренной артерии все еще актуальна. Несмотря на возможность реваскуляризации нижних конечностей через глубокую артерию бедра, сохраняется высокий процент ампутаций. Сроки проходимости реконструированной глубокой бедренной артерии в несколько раз выше проходимости бедренно-подколенных и бедренно-берцовых шунтов в отдаленном послеоперационном периоде. Также нет четких критериев прогноза эффективности реконструктивных вмешательств на глубокой бедренной артерии у больных с мультисегментарными поражениями артерий нижних конечностей после первичных вмешательств, поэтому не существует единой хирургической тактики. Применение глубокой бедренной артерии у больных с ишемией нижних конечностей объясняется малой травматичностью и эффективностью после ряда ранее выполненных многоэтажных операций, тяжелых поражениях дистального русла, а также у пациентов с тяжелыми сопутствующими заболеваниями.
