The impact of innovations in the production of biologically valuable food products on supply chain management in the regional economy

Abstract— The article shows a study of the role of supply chain management of innovative biologically valuable food products in the industrial development and economy of the region. The analysis of the process of updating the assortment of food products based on the introduction of innovative developments and production principles conducive to the release of a healthy diet product (innovative product) is presented. The main provisions of the concept of healthy food products, the category of “innovative food products” are analyzed. The article systematizes the definitions of the concept of “innovative product”. Based on the results of the study, features, functional properties and characteristic features of an innovative food product are determined. Based on the concept of “innovative food product”, the concepts of “new food product”, “improved food product”, and “modified food product” are formulated. A classification model of innovative food products is presented. Based on it, it is shown that the development, production and sale of an innovative food product two functions: economic and social. The study made it possible to formulate the main criteria that make it possible to attribute a food product to a group of innovative food products. The article describes the characteristics of an innovative food product, describes market and consumer properties. The author's definitions of concepts are given: “innovative food product”, “new food product”, “improved food product”, “modified food product”. A classification of innovative food products is proposed

Лечение высокоэнергетических повреждений грудного и поясничного отделов позвоночника

Introduction. Surgical treatment of patients with spinal injuries with traumatic spinal canal stenosis is an important and widely discussed problem of contemporary vertebrology. Injuries to the spine in the incidence structure of isolated or combined injuries occupy a special place due to their high social and clinical significance. Long-term outcomes of traumatic disease in patients with combined trauma to the thoracic and lumbar spine are studied, as before, by ever larger groups of researchers in connection to the new generations of spinal fixation devices being introduced.Materials and methods. 111 patients with various thoracolumbar spine injuries treated surgically were included in the study. In 40 patients, the post-traumatic stenosis was treated with the use of ligamentotaxis and transpedicular osteosynthesis. Thll–Thl2, Th12–L1 and L1–L2 were the most frequent localisations of the level of injury in the study group.Results and discussion. The immediate treatment outcomes observed were as follows — good in 33 (82.5%) cases, satisfactory in 6 (15.0%), unsatisfactory — in 1 (2.5%). Long-term outcomes with follow-up longer than a year were recorded in 27 (67.5%) patients with good outcomes in 20 (74.1%) and satisfactory in 7 (25.9%).Conclusion. A correct stabilisation with metal systems makes it possible to verticalize the patient quickly and shorten the rehabilitation period in all patients including those of active working age, as well as minimize the risks in the long term.Введение. Хирургическое лечение пациентов с повреждениями позвоночника, сопровождающимися травматическим стенозом позвоночного канала, является актуальной и обсуждаемой проблемой современной вертебрологии. Повреждения позвоночника в структуре изолированной и множественной травмы занимают особое место по причине высокой социальной и клинической значимости. Отдаленный период травматической болезни при сочетанной травме грудного и поясничного отделов позвоночника по-прежнему изучается большими группами исследователей в связи с внедрением новых поколений фиксаторов.Материалы и методы. Проведено оперативное лечение 111 больных с различными повреждениями грудопоясничного отдела позвоночника. У 40 больных проведено устранение посттравматического стеноза методом лигаментотаксиса с применением транспедикулярного остеосинтеза. Наиболее частыми локализациями уровня повреждения среди пациентов с повреждениями грудопоясничного отдела в группе исследования были сегменты позвоночного столба на уровне Thll–Thl2,Тh12–L1 и L1–L2.Результаты и обсуждение. Ближайшие результаты лечения прослежены у всех пациентов: хорошие получены в  33  (82,5  %) случаях; удовлетворительные  — в 6 (15,0  %), неудовлетворительные  — в 1 (2,5  %). Отдаленные результаты со сроком наблюдения более 1 года прослежены у 27 (67,5 %) пациентов; у 20 (74,1 %) получены хорошие, у 7 (25,9 %) — удовлетворительные.Заключение. Корректная стабилизация металлоконструкцией позволяет в кратчайшие сроки вертикализировать пациента и сократить сроки реабилитации, в том числе у пациентов трудоспособного возраста, с наибольшей вероятностью минимального возникновения риска в отдаленном период
