Ч еловек служит домом для загадочной экосистемы микробов. В настоящее время микробиота признана новым «эктракорпоральным органом», который, бесспорно, участвует в поддержании гомеостаза нашего организма. В последние десятилетия реализован ряд крупных проектов, направленных © Коллектив авторов, 2020 Адрес для корреспонденции: Карпеева Юлия Сергеевна-к.м.н., ст. науч. сотр. лаборатории медико-социальных проблем в педиатрии НИЦ Санкт-Петербургского государственного педиатрического медицинского университета,
The probiotic fermented milk products hold a specific place in the children diet. As a rule, the pediatricians, when advising the parents, are guided by the characteristics of both strains used as the ferment and the probiotic strains included into the food product. It is important that the microorganisms are safe, shelf stable and able to survive in the gastrointestinal tract. The use of the probiotic fermented milk products has a positive effect on the child health, as follows: anti-infectious and immunomodulatory effects, it helps to normalize the motion of the gastrointestinal tract. These provisions shall be supported with the controlled studies.
One of the main strategies for preventing chronic diseases is a balanced diet from early childhood, with the inclusion of functional ingredients: dietary fiber, vitamins and vitamin-like compounds, minerals, polyunsaturated fatty acids, prebiotics and probiotics. A combined enrichment of fermented dairy products with prebiotics and probiotics contributes to the summation of their positive effective influence. Adding prebiotics and probiotics to the diet leads to the change in the intestinal microbiota composition towards a more balanced structure, thereby increasing the intestinal barrier function and the formation of optimal immune interactions. The most commonly used in human nutrition is a combination of bifidobacteria or lactobacilli with fructo-oligosaccharides in synbiotic products. It is important that the microorganisms are safe, stable in storage and able to survive in the gastrointestinal tract. The use of probiotic fermented dairy products has a positive impact on child health: it has anti-infectious and immunomodulatory effects, helps to normalize the gastrointestinal motility. These statements are confirmed by controlled studies in which children aged 8 to 18 months, recovering from acute respiratory disease, for which antibiotic therapy was prescribed, included in the diet drinking yoghurts enriched with Bifidobacterium lactis BB12 and inulin for 3 months. The inclusion of yoghurts in the children’s diet helped to normalize the intestinal microbiota composition after antibiotic therapy, as well as to strengthen the immune system by stimulating the synthesis of protective factors – secretory immunoglobulin A and lysozyme.

The review presents current data on the interaction between the human body and the community of microorganisms inhabiting its gastrointestinal tract. The terminology and methods for analyzing quantitative and qualitative characteristics of gut microbiota are presented. The review also focuses on the concepts of eubiosis, dysbiosis, and the possibilities of correcting dysbiosis with probiotics and probiotic foods.
The discovery of the gut-bone axis promoted the development of treatment strategies aimed to preserve bone mineral density. Probiotics and probiotic complexes in combination with bone mineral matrix are gradually becoming a new treatment method for osteoporosis. This literature review aims to explore the role of gut microbiota in osteoclastogenesis, bone healing, mechanisms of its effects, and possible ways to modify the microbiota in order to improve bone metabolism. Key words: gut microbiota-bone axis, osteogenesis, osteoporosis, microbiota, nutritional support, baby formula, inulin
Breastfeeding remains the "gold standard" for feeding babies in the first year of life. Breast milk contains a mixture of nutrients; their amount varies throughout the lactation period and even throughout the day. The composition of breast milk (BM) is complex and dynamic. Currently, BM oligosaccharides (BMOs) are of most interest to researchers. Due to advances in science and biotechnology, more than 200 BMOs have been identified. Human BM is the richest source of oligosaccharides among all mammals (for instance, their content in cow's milk is almost 1,000 times lower). Numerous favorable effects of BMOs on child health are related to the immune response, gut barrier function, and protection against pathogens. BMOs as prebiotics contribute to the formation of the infant's intestinal microbiome. The BM contains a complex bacterial community whose composition depends on the maternal microbiome (skin, gut, genital, urethral tracts) that forms the infant gut microbial community. In the absence of breastfeeding, modern formulas can be used; BMOs in their composition make them more like BM.
Despite significant achievements in oncopediatrics there is an increasing amount of children with remote consequences of anticancer treatment. Nutritional disorders are one of the key consequences, the main factors of which are taste disorders. Despite the interest in this issue, an increase in the number of studies, the exact genesis and causal relationships of these violations have not yet been established.Objective. To study the characteristics of taste perception in children with hemoblastosis and CNS tumors after treatment. Material and methods. The authors carried out a cross-sectional study, which included 110 children with hematological malignancies (42 patients) and CNS tumors (68 patients) aged from 10 to 17 years. The after – treatment period was 2–5 years. They analyzed the nutritional screening data (body mass index and survey data). A test for the identification of four tastes (sour, bitter, salty, sweet) was carried out with the solutions in a regulated concentration according to the standard GOST ISO 3972-2014.Results. The majority of children had violations of taste: to bitter taste – 64,6%, sweet – 40%, sour – 43,7%, salty – 33,6%. Children with hemoblastosis had more disorders.Parageusia was more common in children with CNS tumors. Obese children have a greater proportion of these disorders compared to children with malnutrition and normal nutritional status. There is no relationship with the frequency of food intake, its regularity andappetite.Conclusion. The authors have confirmed the presence of nutritional disorders and problems with taste perception that persist for a long time after the end of treatment. Apparently, a significant part of them has a peripheral genesis.
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.
