[The development of children nutrition science in Russia].

The article presents the main directions of children nutrition science in Russia, that starts at the Institute of Nutrition (nowadays Federal Research Centre of Nutrition, Biotechnology and Food Safety). Almost all areas of children nutrition - from early age to adulthood, from the organization of public nutrition to personalized approaches - were developed on the base of the Department of Children Nutrition, founded in 1932. Years of beneficial work of famous Russian specialists in the field of pediatric dietetics and nutrition science are associated with this Department, for instance professors E.M. Fateeva, K.S. Ladodo, I.Ya. Kon and their followers. The priority role of the Department of Children Nutrition in different areas of nutrition science is also shown in the article, for example in the development and improvement of physiological needs in nutrients and energy for children, pregnant and nursing women; development of new specialized infant foods, including first Russian formulas. Perinatal nutrition science, fundamental research on the composition of breast milk, creation of the system supporting breastfeeding, and design of dietary approaches to the correction of alimentary-dependent diseases were developed. The research on the effects of the hormonal composition of breast milk on the growth rate of infants who are breastfed has attracted the interest of the world scientific community. In recent years, fundamentally new scientific directions have been formed, based on the theory of "food programming", and nutrigenetic research has been developed. An important impetus in the development of modern pediatric nutritional science is the introduction of new approaches based on the achievements of nutritional metabolomics, nutrigenomics and nutrigenetics, digital technologies, and innovations in the field of food production. Nowadays children's nutrition in our country has confidently developed into an independent scientific direction, its main sections have been clearly identified: prenatal nutrition; infant and toddler nutrition; nutrition of preschool and school-age children; epidemiology of child nutrition; technologies for the production of infant and baby food and its safety.

Nutrition for Preterm Infants: 75 Years of History.

As technology has advanced, survival rates of preterm infants have improved dramatically. Human milk was the primary source of enteral nutrition during the early days of neonatology, but the HIV/AIDS epidemic resulted in an increased use of preterm formula. More recently, the benefits of human milk were rediscovered, resulting in increased use of donor human milk as well. The awareness that human milk does not contain the amounts of nutrients to meet the high requirements of infants born premature resulted in the development of human milk fortifiers. The development of these fortifiers is still ongoing, as are alternative methods of pasteurization of donor milk. Those initiatives will increase the use of human milk with consequently short- and long-term benefits for preterm infants.

Chapter 1. The Historical Roots of Paediatric Gastroenterology, Hepatology, and Nutrition.

The last 50 years have seen the establishment of paediatric gastroenterology, hepatology, and nutrition (PGHAN) as a well-recognised and thriving clinical specialty throughout most of Europe, and further afield. This has happened, in part, through the existence of the European Society for Paediatric Gastroenterology and Nutrition (ESPGHAN) as a forum for those interested in this branch of children's medicine. To illustrate the pan-European roots of PGHAN, some key scientific and medical events, discoveries, and inventions relevant to 3 common clinical problems-diarrhoea, jaundice, and infant-feeding-have been chosen to survey the historical development of the ways in which each was understood and treated within the changing thinking and practice of past times. Together they are used to trace the prehistory of ESPGHAN and provide a background against which to explain the genesis of the Society and how its spheres of clinical and scientific interest came to be defined.

Chapter 2. ESPGHAN: 50 Years Memories-The Early Years.

Thirty-six founding members from Europe were present in 1968, when the European Society of Paediatric Gastroenterology (ESGA) had its first meeting in Paris. The aim was to create a forum for presentations and discussions of research activities in paediatric gastroenterology in Europe. At the second meeting of ESGA 1969 in Interlaken, an important landmark was set for all gastroenterologists in the world. In this conference, the first ever criteria for "the Diagnosis of Coeliac Disease" (CD) were established. In 1990, the revised criteria for the diagnosis of CD were published. After the introduction of new noninvasive techniques, like tissue transglutaminase 2-antibodies and the HLADQ2/HLADQ8 determinations in blood, "new" criteria for the diagnosis of CD were published in 2012 by the European society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Close collaboration of ESPGHAN and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition led to mutual meetings. The first combined meeting was 1978 in Paris, followed by meetings in New York, Amsterdam, Houston, and last in Toulouse. The first World Congress of Paediatric Gastroenterology took place in Boston 2000 followed by congresses in Paris, Iguazu, Taipeh, and Toronto. The creation of specialised committees (Nutrition Committees, GI-Committee, and Hepatology-Committee) enabled the society to elaborate numerous guidelines for standards in the diagnosis and treatment of diseases within the subspecialties. The Journal of Paediatric Gastroenterology and Nutrition, as organ of ESPGHAN and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition since 1991, serves as the voice for these worldwide accepted guidelines. Growing educational activities with summer schools, the Young Investigator Forum and the creation of working groups have distributed our current knowledge among the younger generation and led to fruitful reports, guidelines, and syllabus. In 1992, ESPGHAN was 1 of the founding 7 members of the United European Gastroenterology Federation (UEGF), which developed into a successful organisation for gastroenterology in Europe. This year we celebrate the 50th anniversary of ESPGHAN at our annual Meeting in Geneva.

Chapter 3. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition in Recent Years.

The European Society for Paediatric Gastroenterology, Hepatology and Nutrition has experienced an amazing development in the 50 years of its existence. It grew from a small group of 36 friends who held an informal meeting with some 20 oral presentations to share and discuss their clinical and research work, to a large, multiprofessional society that sets widely recognized standards for clinical care and policy and hosts the world's largest congress of Paediatric Gastroenterology, Hepatology and Nutrition with more than 4500 delegates from 100 countries. However, the Society's mission has remained the same: to promote the health of children with special attention to the gastrointestinal tract, liver, and nutritional status, through knowledge creation, the dissemination of science based information, the promotion of best practice in the delivery of care and the provision of high-quality education. The European Society for Paediatric Gastroenterology Hepatology and Nutrition's success is based on the enthusiasm and engagement of its membership that contribute extensive volunteer work to support child health, while maintaining a positive spirit of collaboration and friendship, which characterises this Society. This article aims at describing recent developments and the current situation of the European Society for Paediatric Gastroenterology Hepatology and Nutrition.

Chapter 4. The Relationship Between the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition.

This chapter is based on the memories of those who shaped the relationship between the European and the North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. The first joint meeting of the 2 Societies took place in Paris in 1978, followed by 1 in New York in 1985, 1 in Amsterdam in 1990, 1 in Houston in 1994, and the last one in Toulouse in 1998. The formation of the Federation of the International Societies for Pediatric Gastroenterology, Hepatology and Nutrition (FISPGHAN) preceded the First World Congress of all Societies, which took place in Boston in 2000. The success of this meeting was followed by world congresses in Paris in 2004, Iguassu in 2008, Taiwan in 2012, and Montreal in 2016. NASPGHAN and ESPGHAN jointly took on the direction of the Journal of Pediatric Gastroenterology and Nutrition in 1991. Communication between the 2 Societies is extremely active, with members participating in many joint projects.
