The treatment of chronic wounds is a continuously developing research focus. The problems of excessive mechanical forces, infection, inflammation, reduced production of growth factors, and lack of collagen will affect the results of treatment. The purpose of this study was to analysse the elements that lead to long-term non-healing of chronic wounds and trophic ulcers, including diabetic foot syndrome, by determining the optimal treatment algorithm. The paper presents an analysis of the world literature on the etiopathogenesis and principles of chronic wound treatment in diabetic foot syndrome. The epidemiology of chronic wounds of different genesis is presented. The issues of physiological and metabolic disorders in chronic ulcers affecting the process of wound healing are discussed. Particular attention is paid to collagen, which is a protein that forms the basis of connective tissue; collagen ensures the strength and elasticity of the skin, which confirms the importance of its role not only in aesthetics but also in the process of wound healing. Different types of collagen and their roles in the mechanisms of chronic wound healing in diabetic foot syndrome are described. The results of clinical studies evaluating the effectiveness of medical products and preparations, consisting of collagen with preserved (native collagen) and fractionated structures, in treating chronic wounds of diabetic foot syndrome are analysed. It has been shown that the use of native collagen preparations is a promising treatment for chronic ulcers and wounds, including diabetic foot syndrome, which makes it possible to increase the effectiveness of treatment and reduce the economic costs of managing these patients.
The aim of this study was to assess the patterns and pattern disruptions of free radical processes in patients with obstructive jaundice of various origins, and the severity of jaundice before and after decompression. Oxidative stress markers were determined in 128 patients with obstructive jaundice with a tumor genesis (23.4%) or non-tumor genesis (76.6%). The patients were hospitalized at different stages of clinical signs of jaundice. We studied the anti-peroxide activity in plasma, basal and stimulated indicators of the chemiluminescence intensity in leukocytes, leukocyte activity coefficients reflecting the level of reactive oxygen species generated by leukocytes, malondialdehyde levels indicative of the degree of lipid peroxidation and cellular destruction, liver enzymes (markers of cytolysis) and bilirubin levels. Data for hepatocyte death and markers of oxidative stress correlated with the severity of jaundice, its duration and the method of its surgical correction. It is proposed that using markers of free radical processes to assess the prognosis and effectiveness of treatment and to personalize treatment measures will improve the results of jaundice treatment.
общество по изучению и эффективному контролю стресса и связанных с ним расстройств, Москва, Россия В настоящее время большую актуальность приобретают исследования, направленные на повышение осведомленности о различных заболеваниях среди населения. Различные обучающие программы, посвященные быстрому распознаванию признаков инсульта, могут быть направлены на обучение детей и подростков. Цель исследования-изучение результатов уроков «СТОП-ИНСУЛЬТ» в школах Москвы. Материал и методы. Молодежный совет Департамента здравоохранения Москвы (ДЗМ) совместно с Фондом «ОРБИ» провел открытые уроки «СТОП-ИНСУЛЬТ» среди учеников московских школ. В исследование были включены результаты обучения 29 653 учеников 4-10-х классов, которые заполнили специально разработанную анкету до и после лекции, в которой объяснялись основные симптомы инсульта, а также действия, которые необходимо предпринимать при подозрении на его возникновение. В лекцию был включен мнемонический тест УДАР (улыбка, движение, афазия, решение). Результаты. Выявлено, что после обучения улучшились знания о симптомах инсульта (афазия, слабость мышц лица, слабость в конечностях) и мер, которые необходимо предпринять при подозрении на его возникновение. Значимо возросло число детей, правильно указавших три симптома заболевания. Заключение. Результаты исследования продемонстрировали эффективность программы. Прошедшие обучение дети могут быстрее вызвать скорую медицинскую помощь, если у члена семьи возникает инсульт. Необходимы дальнейшие исследования, направленные на оценку эффективности данных лекций, в том числе и в долгосрочном периоде.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
