Posted in 2022, Issue № 04 (118) April 2022, MEDICINE | 0 comments

In today’s Russian healthcare, the problem of saving labor and financial resources is quite urgent. One of the promising management principles is lean manufacturing, which is aimed at reducing costs while improving the efficiency and quality of medical services. There are works testifying to the positive results of the use of lean technologies in the healthcare systems of different countries. In recent years, a new model of a medical organization providing primary health care using lean manufacturing methods has also been implemented in Russia. The purpose of the study was to assess the possibility of using the principles of lean manufacturing in the development of occupational pathology services (based on the Republic of Tatarstan).Research material: data from the Department of Rospotrebnadzor of the Republic of Tatarstan, the register of occupational Diseases of the Republican Center of Occupational Pathology, primary documentation of patients with occupational pathology. Research methods: statistical, lean technology method (value stream mapping).

Results. The article analyzes the main aspects of the interaction between patient, doctors, and the nursing staff, and determines the algorithm of actions of the medical staff / patient in the flow of actions for the examination of the connection of the disease with the profession. The authors identifies bottlenecks and losses in the workflow during the provision of occupational pathology care as well as determines ways of solving the implementation of the necessary actions for the transition to the target state. Conclusion: the provision of primary health care in occupational pathology is accompanied by certain losses. The use of lean technology methods will optimize the logistics of patient movement during the examination of the connection of the disease with the profession and the examination of professional suitability. The analysis of the flow problem made it possible to identify solutions and develop a step-by-step plan for implementing the necessary actions to move to the target state.

Posted in 2022, AGRICULTURE, Issue № 04 (118) April 2022 | 0 comments

The typological structure is the classification basis of forest conditions. To study the typological structure, the research uses 542 plots of fir plantations of the Republic of Khakassia. The research describes the following types of forest in the area under study: Aconitum fir forest (Pikhtach bortsovy), Geranium fir forest (Pikhtach geranevy), green-moss fir forest (Pikhtach zelenomoshnikovy), Oxyria fir forest (Pikhtach kislichny), Fern fir forest (Pikhtach paportnikovy), Carex-Sphagnum fir forest (Pikhtach osochkovo-sfagnovy), medium-mountain fir and horsetail-carex fir forest (Pikhtach srednegorny and Pikhtach khvoshchyovo-osokovy). The authors determined insignificant differences in survey and orographic indicators for most types of fir forests. However, a significant difference was identified between the firs of the Aconitum, medium-mountain, green-moss, geranium and Oxyria groups, which is due to the conditions in their place of growth.

ON THE FEATURES OF HEART RATE IN 16-17-YEAR-OLD FOOTBALL PLAYERS

Posted in 2022, Issue № 04 (118) April 2022, MEDICINE | 0 comments

The study was conducted over two academic years (the beginning and the end of each academic year) with the same contingent of students aged 16-17 years engaged and not engaged in football. The experiment was conducted in a youth sports school. The average sports experience by the end of the study was 7 years. The control group was engaged in physical culture two hours a week. The aim of the study was to examine the heart rate variability in football players aged 16-17 and their peers who do not play sports. The study determined the features of the adaptation of the heart rate of young football players and their peers who were not involved in football.

By the end of the first year of the study, the sympathetic type of regulation increases in football players (41.67%), which indicates the tension of adaptation mechanisms. The same pattern was found in young men who were not involved in sports by the end of the second year of the study. It was found that at the end of the second year of the study, according to the degree of activation of the parasympathetic department of the autonomic nervous system, two groups were identified: 50% registered normal values, while the second half showed the tension of the heart rhythm mechanisms and unsatisfactory adaptation. The results obtained expand the understanding of the age-related features of the functioning of the cardiovascular system during physical exertion of different capacities in athletes.

ЭПИДЕМИОЛОГИЧЕСКИЕ АСПЕКТЫ ТОКСОКАРОЗА ЧЕЛОВЕКА В АСТРАХАНСКОМ РЕГИОНЕ

Posted in 2022, Issue № 04 (118) April 2022, MEDICINE | 0 comments

Заболевание токсокароз имеет большую заинтересованность для врачей, так как при данном заболевании патологический процесс затрагивает разные системы организма. При данном заболевании наблюдается широкое разнообразие клинической симптоматики, а также методов диагностики и тактики лечения.

С 2016 по 2020 гг. в Астраханском регионе было зафиксировано 36 эпизодов токсокароза человека. За исследуемый нами срок, на долю токсокароза пришлось 0,4% эпизодов и 0,2% – от общего количества всех гельминтозов, которые были зарегистрированы в Астраханском регионе за 2016 – 2020 гг.

Токсокароз может наблюдаться как у детей, так и у взрослых. Так, на долю возрастного населения пришлось 83,6%, в т.ч. работающее население – 66,8%, пенсионеры – 12,3% и нетрудоустроенные – 3,4%.

На долю детей по заболеваемости токсокарозом пришлось 18,3%, среди которых, посещали ДДУ – 12,3%, средние общеобразовательные школы – 3,2%, еще один ребёнок – был дома с родителями – 3%.

Основными клиническими симптомами лиц, которые обратились в медицинское учреждение, были: сухой кашель – 22,8%, астения – 18,2%, болезненность в эпигастрии, а также субфебрильную температуру тела – по 12,4%, вазомоторный ринит и миалгию с артралгией – по 5,7%.

Также больные предъявляли жалобы на понижение аппетита, дерматит, одышку и потерю массы тела – по 2,7%.

После того как был проведен эпидемиологический анамнез было выяснено, что наиболее частыми факторами развития заболевания были: не соблюдение правилами личной гигиены – 93,8%, приём в пищу не мытых овощей и фруктов – 87,9%, тесная связь с домашними питомцами – 63,5%, обкусывание ногтей (онигофагия) – 21,3%, потребления в пищу земли и различных земельных пород (мел, глина) и облизывание рук – по 8,7%.

Основным выбором метода лабораторной диагностики токсокароза был – мeтoд иммyнoфepмeнтнoго исследования, с помощью которого выявлялись aнтитeла к антигенам токсокар с иммyнoглoбyлинaми класса J (фирма ЗАО «Вектор-Бест», г. Ростов).

Выводы: таким образом, проблема токсокароза человека остается актуальной на сегодняшний день, это доказывают новые случаи заболевания человека. Возрастная категория граждан была различна, заболевание затрагивает как детей, так и взрослых. Наиболее частыми факторами риска развития болезни считаются близкий контакт с животными и не соблюдение основ личной гигиены. Доказательством присутствия паразитарной инфекции у больных служит, обнаружение у болеющих граждан титра антител 1:800 и выше, и вдобавок присутствие клинических симптомов болезни.

PRP-ТЕРАПИЯ ЯИЧНИКОВ: МОЛЕКУЛЯРНЫЕ АСПЕКТЫ

Posted in 2022, Issue № 04 (118) April 2022, MEDICINE | 0 comments

Бесплодие – заболевание, характеризующееся невозможностью достичь клинической беременности после 12 месяцев регулярной половой жизни без контрацепции вследствие нарушения способности субъекта к репродукции.
В последние годы увеличилась частота встречаемости этого диагноза по причине преждевременной недостаточности яичников, а низкий овариальный резерв совместно с «бедным» ответом яичников на стимуляцию остаются основными факторами бесплодия у женщин старшего репродуктивного возраста. Применение вспомогательных репродуктивных технологий у данных пациенток ассоциировано с низкой частотой наступления беременности. Обогащенная тромбоцитами плазма (PRP), содержащая различные факторы роста, усиливающие регенерацию, ангиогенез и процесс пролиферации клеток, представляет собой интерес как метод преодоления бесплодия при вышеупомянутых состояниях.

An Analysis of the Optimality Criteria for the Movement of the Working Body of a Mixing Mechanism

Posted in 2022, ENGINEERING, Issue № 04 (118) April 2022 | 0 comments

The device proposed in this article relates to spatial lever-screw mechanisms and can be used in the food, medical, chemical, construction industries, as well as in agriculture, as a device necessary for the preparation of homogeneous media, allowing for intensifying mass and heat exchange processes, equalize the concentration and temperature in the entire volume of mixed substances by increasing the contact surface phases, to ensure an even distribution of energy in the volume of the apparatus.

In agriculture, the mixing process is used in the preparation of various liquid fertilizers that increase the fertility of cultivated areas, multicomponent pesticides for etching seeds before sowing; in the chemical, pharmaceutical and medical industries such as the preparation of medicinal substances; in the food industry – in the preparation of cheese curds (V. Guileta, N. Chusovitin. Dispositis de mélange: diplôme d`une médaille d`or. Concours Lépine le salon Europeen de l’invention de Strasbourg. – Strasbourg, 2011), in confectionery production – in order to replace monotonous manual operations; in mechanical engineering – in the manufacture of grinding wheels; in the construction industry – in the production of fine ceramic products.

Despite the fact that most of the designs of the mechanical mixing devices used were created on the basis of practical experience without sufficient justification, they dominate in the world practice. This fact is explained by the versatility of such devices, the reliability of their designs, and high efficiency compared to mixing devices of other types.
