Dietary recommendations during the Covid-19 pandemic. Statement of the Committee of Human Nutrition Science of the Polish Academy of Sciences.

During the COVID-19 pandemic, care for an adequate diet, well adapted to the body's needs and the current level of physical activity, becomes of particular importance. Many dietary compounds participate in the functioning of the immune system, while vitamins D, C, A (including beta-carotene), E, B6, B12, folic acid, zinc, copper, selenium, iron, amino acids, n-3 and n-6 polyunsaturated fatty acids and intestinal microbiota are crucial in various types of defence processes. There has been no evidence that consumed food and its compounds, including those with pro-/prebiotic properties, play a significant role in preventing SARS-CoV-2 infection or alleviating its course. However, in terms of the nutritional value of food and the prevention of dysbiosis, recommending a varied diet with a high proportion of plant-based foods and an adequate amount of animal-based foods has a sound scientific basis. Malnutrition, underweight and obesity are considered independent and prognostic risk factors of severe SARS-CoV-2 infection, which reduce a patient's chances of survival. Therefore, ensuring good nutritional status, including healthy body weight, is a reasonable approach in the prevention of viral infection SARS-CoV-2 or alleviating its course. The document is accompanied by two catalogues of practical nutritional recommendations during the COVID-19 pandemic, addressed to the general population and children.

Consumption of Sugar-Sweetened Beverages in Paediatric Age: A Position Paper of the European Academy of Paediatrics and the European Childhood Obesity Group.

BACKGROUND: Health risks associated with the high consumption of sugar-sweetened beverages (SSBs) include overweight or obesity and their complications such as diabetes, as well as oral and dental decay, among others. AIM: The aim of the present statement is to inform health care professionals, parents, care-givers, teachers and school head teachers, stakeholders and governing bodies about the risks associated with drinking SSBs in infants, children and adolescents. METHODS: We searched PubMed and the Cochrane databases for English language studies published from 2010 through October 1, 2018, for randomized clinical trials, meta-analyses, systematic reviews and observational studies (search terms are reported in eAppendix in the Supplement). We also manually searched the references of selected articles, reviews, meta-analyses and practice guidelines. RECOMMENDATIONS: Consumption of SSB by children and adolescents should be limited, and the consumption of water and other non-sweetened beverages should be promoted. Educational institutions such as nurseries, pre-schools and schools should offer unlimited access to drinking water, whereas the sale of SSBs should be banned.

Pediatric Nonalcoholic Fatty Liver Disease: Current Thinking.

Nonalcoholic fatty liver disease (NAFLD), an increasingly prevalent paediatric disorder, is diagnosed and managed not only by both pediatric gastroenterologists/hepatologists but also frequently by the general pediatrician. This article updates recent advances in diagnostic and therapeutic approach, which may be applied to everyday practice. Diagnosis of NAFLD takes into account the risk factor profile and is a diagnosis of exclusion. Techniques such as transient elastography and specific biomarkers aimed at improving diagnosis and monitoring of NAFLD need further validation in the pediatric population. Defining the risk to develop cirrhosis seems to be of primary importance already in childhood and a combination of genetic, clinical, and environmental factors can help in monitoring and making decisions on therapy. Weight reduction therapy should be the aim of treatment approach, but the compliance is poor and pharmacological treatment would be helpful; docosahexaenoic acid, some probiotics, and vitamin E are to be considered, but evidence is not sufficient to recommend widespread use.

The Health Care Transition of Youth With Liver Disease Into the Adult Health System: Position Paper From ESPGHAN and EASL.

BACKGROUND: Medical advances have dramatically improved the long-term prognosis of children and adolescents with once-fatal hepatobiliary diseases. However, there is no generally accepted optimal pathway of care for the transition from paediatric care to the adult health system. AIM: The purpose of this position paper is to propose a transition process for young people with paediatric onset hepatobiliary diseases from child-centred to adult-centred healthcare services. METHODS: Seventeen ESPGHAN/EASL physicians from 13 countries (Austria, Belgium, France, Germany, Hungary, Italy, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, and United Kingdom) formulated and answered questions after examining the currently published literature on transition from childhood to adulthood. PubMed and Google Scholar were systematically searched between 1980 and January 2018. Quality of evidence was assessed by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) system. Expert opinions were used to support recommendations whenever the evidence was graded weak. All authors voted on each recommendation, using the nominal voting technique. RESULTS: We reviewed the literature regarding the optimal timing for the initiation of the transition process and the transfer of the patient to adult services, principal documents, transition multi-professional team components, main barriers, and goals of the general transition process. A transition plan based on available evidence was agreed focusing on the individual young people's readiness and on coordinated teamwork, with transition monitoring continuing until the first year of adult services.We further agreed on selected features of transitioning processes inherent to the most frequent paediatric-onset hepatobiliary diseases. The discussion highlights specific clinical issues that will probably present to adult gastrointestinal specialists and that should be considered, according to published evidence, in the long-term tracking of patients. CONCLUSIONS: Transfer of medical care of individuals with paediatric onset hepatobiliary chronic diseases to adult facilities is a complex task requiring multiple involvements of patients and both paediatric and adult care providers.

Early and Late Factors Impacting Patient and Graft Outcome in Pediatric Liver Transplantation: Summary of an ESPGHAN Monothematic Conference.

As pediatric liver transplantation comes of age, experts gathered to discuss current paradigms and define gaps in knowledge warranting research to further improve patient and graft outcomes. Identified areas ripe for collaborative research include understanding the molecular and cellular mechanisms of tolerance and the role of donor-specific antibodies, considering ways to expand donor pool, minimizing long-term side effects of immunosuppression, and fine-tuning surgical techniques to minimize biliary and vascular complications.

Influence of Partial External Biliary Diversion on the Lipid Profile in Children With Progressive Familial Intrahepatic Cholestasis.

OBJECTIVES: The concentration of bile acids is highly increased in progressive familial intrahepatic cholestasis (PFIC). Bile acids are the end products of cholesterol metabolism, and aid in the absorption of fat-soluble vitamins and dietary fat. The aim of our study was to investigate lipid metabolism in patients with PFIC with focus on the effect of partial external biliary diversion (PEBD). METHODS: In 26 patients with PFIC, who underwent PEBD surgery at the median age of 2.2 years (range: 0.4-16.6), we analyzed the concentrations of lipids and apolipoproteins both before and 6 months after PEBD. Patients were split into 2 groups according to the outcome of surgery (either "good" or "poor"), and were analyzed separately. A "good" result following surgery was defined as complete relief from pruritus, and normalization of total bilirubin (<1.0 mg/dL) and bile acid concentration in serum (<12 µmol/L). RESULTS: We found abnormal lipid concentrations at baseline in all 26 patients: cholesterol was increased (>190 mg/dL) in 13 patients, phospholipids were increased (>250 mg/dL) in 5 patients, and triglyceride concentration was increased (>150 mg/dL) in 13 patients. After PEBD, the concentrations of plasma cholesterol, triglycerides, and phospholipids decreased significantly, whereas, ApoA-I and high-density lipoprotein cholesterol concentrations increased and the concentrations of apolipoprotein B, low-density lipoprotein cholesterol, and very low-density lipoprotein cholesterol significantly decreased. PEBD had neither an effect on ApoE concentration nor on lecithin-cholesterol acyl transferase activity. In the group with a "poor" outcome report following PEBD, total serum cholesterol concentration decreased significantly, and no effect on the concentrations of triglycerides and phospholipids were observed. CONCLUSIONS: Patients with PFIC present with a high risk of lipid disturbances. PEBD has a beneficial effect on lipid profile in the majority of cases.

Childhood Obesity: Position Statement of Polish Society of Pediatrics, Polish Society for Pediatric Obesity, Polish Society of Pediatric Endocrinology and Diabetes, the College of Family Physicians in Poland and Polish Association for Study on Obesity.

Childhood obesity is one of the most important problems of public health. Searching was conducted by using PubMed/MEDLINE, Cochrane Library, Science Direct, MEDLINE, and EBSCO databases, from January 2022 to June 2022, for English language meta-analyses, systematic reviews, randomized clinical trials, and observational studies from all over the world. Five main topics were defined in a consensus join statement of the Polish Society of Pediatrics, Polish Society for Pediatric Obesity, Polish Society of Pediatric Endocrinology and Diabetes and Polish Association for the Study on Obesity: (1) definition, causes, consequences of obesity; (2) treatment of obesity; (3) obesity prevention; (4) the role of primary care in the prevention of obesity; (5) Recommendations for general practitioners, parents, teachers, and regional authorities. The statement outlines the role of diet, physical activity in the prevention and treatment of overweight and obesity, and gives appropriate recommendations for interventions by schools, parents, and primary health care. A multisite approach to weight control in children is recommended, taking into account the age, the severity of obesity, and the presence of obesity-related diseases. Combined interventions consisting of dietary modification, physical activity, behavioral therapy, and education are effective in improving metabolic and anthropometric indices. More actions are needed to strengthen the role of primary care in the effective prevention and treatment of obesity because a comprehensive, multi-component intervention appears to yield the best results.

Influences of Parental Snacking-Related Attitudes, Behaviours and Nutritional Knowledge on Young Children's Healthy and Unhealthy Snacking: The ToyBox Study.

This study investigated parental influences on preschool children's healthy and unhealthy snacking in relation to child obesity in a large cross-sectional multinational sample. Parents and 3-5 year-old child dyads (n = 5185) in a kindergarten-based study provided extensive sociodemographic, dietary practice and food intake data. Parental feeding practices that were derived from questionnaires were examined for associations with child healthy and unhealthy snacking in adjusted multilevel models, including child estimated energy expenditure, parental education, and nutritional knowledge. Parental healthy and unhealthy snacking was respectively associated with their children's snacking (both p < 0.0001). Making healthy snacks available to their children was specifically associated with greater child healthy snack intake (p < 0.0001). Conversely, practices that were related to unhealthy snacking, i.e., being permissive about unhealthy snacking and acceding to child demands for unhealthy snacks, were associated with greater consumption of unhealthy snacks by children, but also less intake of healthy snacks (all p < 0.0001). Parents having more education and greater nutritional knowledge of snack food recommendations had children who ate more healthy snacks (all p < 0.0001) and fewer unhealthy snacks (p = 0.002, p < 0.0001, respectively). In the adjusted models, child obesity was not related to healthy or unhealthy snack intake in these young children. The findings support interventions that address parental practices and distinguish between healthy and unhealthy snacking to influence young children's dietary patterns.

[Two cases of Wilson disease diagnosed as autoimmune hepatitis]. / Diagnostyka róznicowa choroby Wilsona i autoimmunologicznego zapalenia watroby.

Authors present two cases of Wilson disease in which the final diagnosis was very difficult and needed the differentiation with autoimmune hepatitis. Observation of those two patients leads to the conclusion that paediatricians have to deepen they knowledge of autoimmune hepatitis and Wilson disease which are seen more often in children now-a-days. It will help to quicker the diagnosis and treatment which is most essential for better prognosis in those patients.

Early obesity prevention: Polish contribution to European projects.

Poland faces the same problem of obesity epidemics as other European countries. Polish contribution to the EU research projects concerning overweight and obesity is a direct consequence of recognition of this problem and scientific activity of Polish researchers. At present time early prevention seems to be the only effective approach to decrease obesity and obesity-related chronic diseases in adulthood. Three studies described here consider early prevention of obesity - by decreasing protein intake in infancy (CHOP and EARNEST study) or by behavioural approach in preschoolers (TOYBOX). The Children's Memorial Health Institute is participating in all these projects as a recruiting centre of the subjects studied and as a central laboratory for the CHOP and EARNEST studies. The CHOP study proved in a randomized trial that high protein intake in infancy increases the risk of obesity. The results of the CHOP studies have already indicated the need for protein reduction in infant formulas. This was reduced to 1.8 g/100kcal in the 2006 EU Directive. The results from the TOYBOX project which was started in 2010 have not yet been published.

Recurrence of non-alcoholic steatohepatitis after liver transplantation in a 13-yr-old boy.

Nonalcoholic steatohepatitis (NASH) is the most severe form of non-alcoholic fatty liver disease (NAFLD). The aim of our study was to highlight NASH as a rare but possible problem in children. We present a case of 13-yr-boy with a well-established diagnosis of liver cirrhosis secondary to NASH, who underwent orthotopic liver transplantation (OLT) at the age of 13 years. Six months after transplantation recurrence of NASH in the graft was diagnosed. In the treatment metformin was used with good effect.
