Training in Paediatric Clinical Nutrition Across Europe: A Survey of the National Societies Network (2016-2019) of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition.

OBJECTIVES/BACKGROUND: Disease-related malnutrition is common in patients with chronic diseases and has detrimental effects, therefore, skills in nutrition care are essential core competencies for paediatric digestive medicine. The aim of this survey, conducted as part of a global survey of paediatric gastroenterology, hepatology and nutrition (PGHN) training in Europe, was to assess nutrition care-related infrastructure, staff, and patient volumes in European PGHN training centres. METHODS: Standardized questionnaires related to clinical nutrition (CN) care were completed by representatives of European PGHN training centres between June 2016 and December 2019. RESULTS: One hundred training centres from 17 European countries, Turkey, and Israel participated in the survey. Dedicated CN clinics exist in 66% of the centres, with fulltime and part-time CN specialists in 66% and 42%, respectively. Home tube feeding (HTF) andhome parenteral nutrition (HPN) programmes are in place in 95% and 77% of centres, respectively. Twenty-four percent of centres do not have a dedicated dietitian and 55% do not have a dedicated pharmacist attached to the training centre. Even the largest centres with >5000 outpatients reported that 25% and 50%, respectively do not have a dedicated dietitian or pharmacist. Low patient numbers on HTF and HPN of <5 annually are reported by 13% and 43% of centres, respectively. CONCLUSIONS: The survey shows clear differences and deficits in Clinical Nutrition training infrastructure, including staff and patient volumes, in European PGHN training centres, leading to large differences and limitations in training opportunities in Clinical Nutrition.

ACUTE RESPIRATORY DISTRESS SYNDROME IN A FOUR-YEAR-OLD BOY WITH DIABETIC KETOACIDOSIS - CASE REPORT.

- Among many disease states as known initiators of acute respiratory distress syndrome (ARDS), diabetic ketoacidosis (DKA) is the rarest one. We present a 4-year-old boy with DKA as the first manifestation of insulin-dependent diabetes mellitus who developed ARDS, required tracheal intubation and mechanical ventilation, and survived without significant sequels. To improve survival of patients with ARDS as a complication of DKA, physicians should be aware of this rare pulmonary complication and its appropriate management.

National Guidelines for the Performance of the Sweat Test in Diagnosis of Cystic Fibrosis on behalf of the Croatian Society of Medical Biochemistry and Laboratory Medicine and the Cystic Fibrosis Centre - Paediatrics and adults, University Hospital Centre Zagreb.

The sweat test (ST) is a cornerstone in the diagnosis of cystic fibrosis (CF), together with newborn screening and genetic testing. However, the performance of the ST can depend on the operator's skill, so several international guidelines have been published to standardise the ST, but inconsistencies remain. The joint Working Group for ST Standardisation (WG STS) of the Croatian Society of Medical Biochemistry and Laboratory Medicine, in association with cistic fybrosis health professional and the Cistic Fibrosis Centre for Paediatrics and Adults, have issued National Guidelines for the Performance of the Sweat Test in order to ensure consistency in ST performance and accuracy of reported results. Many of the standards were taken from the 2nd Edition of the UK Guidelines for Performance of the ST for the Diagnosis of CF, while others were taken from independent consensus statements from the WG STS based on local ST equipment and practices. The standards cover every step of the ST, from the indications for testing to reporting of results and their interpretation, including the analytical phase and quality control. In addition, National Guidelines include appendices with practical examples in order to aid implementation of the recommendations in routine practice.

Pediatric endoscopy training across Europe: a survey of the ESPGHAN National Societies Network 2016-2019.

Background and study aims The ability to perform endoscopy procedures safely and effectively is a key aspect of quality clinical care in Pediatric Gastroenterology, Hepatology and Nutrition (PGHN). The aim of this survey, which was part of a global survey on PGHN training in Europe, was to assess endoscopy training opportunities provided across Europe. Methods Responses to standardized questions related to endoscopy training were collected from training centers across Europe through the presidents/representatives of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition National Societies from June 2016 to December 2019. Results A total of 100 training centers from 19 countries participated in the survey. In 57 centers, the endoscopy suit was attached to the PGHN center, while in 23, pediatric endoscopies were performed in adult endoscopy facilities. Ninety percent of centers reported the availability of specialized endoscopy nurses and 96 % of pediatric anesthetists. Pediatric endoscopies were performed by PGHN specialists in 55 centers, while 31 centers reported the involvement of an adult endoscopist and 14 of a pediatric surgeon. Dividing the number of procedures performed at the training center by the number of trainees, ≤ 20 upper, lower, or therapeutic endoscopies per trainee per year were reported by 0 %, 23 %, and 56 % of centers, respectively, whereas ≤ 5 wireless capsule endoscopies per trainee per year by 75 %. Only one country (United Kingdom) required separate certification of competency in endoscopy. Conclusions Differences and deficiencies in infrastructure, staffing, and procedural volume, as well as in endoscopy competency assessment and certification, were identified among European PGHN training centers limiting training opportunities in pediatric endoscopy.

Training in pediatric neurogastroenterology and motility across Europe: a survey of the ESPGHAN National Societies Network 2016-2019.

Background: Pediatric gastrointestinal motility disorders present significant challenges for diagnosis and management, emphasizing the need for appropriate training in Pediatric Neurogastroenterology and Motility (PNGM). The aim of this survey, part of a comprehensive survey on training in pediatric gastroenterology, hepatology and nutrition, was to evaluate training related to PNGM across European training centers. Method: Standardized questionnaires were collected from training centers through the National Societies Network of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN), from June 2016 to December 2019. Results: In total, 100 training centers from 19 countries participated in the survey. Dedicated PNGM clinics were available in 22 centers; pH-monitoring in 60; pH/impedance in 66; standard manometry in 37; and high-resolution manometry in 33. If all motility studies were performed partially or fully by the trainees, the median (range) annual numbers/per trainee were as follows: pH-monitoring 30 (1-500); pH/impedance 17 (1-131); standard manometries 10 (1-150); and high-resolution manometries 8 (1-75). The motility assessment was performed by pediatric gastroenterologists (43 centers); adult gastroenterologists (10 centers); pediatric surgeons (5 centers); and both pediatric gastroenterologists and pediatric surgeons (9 centers). Annual numbers ≤10 for pH-monitoring, pH/impedance, standard manometries and high-resolution manometries were reported by 7 (12%), 15 (23%), 11 (30%) and 14 (42%) centers, respectively. Conclusions: Significant differences exist in PNGM-related infrastructure, staff and procedural volumes at training centers across Europe. ESPGHAN and the National Societies should take initiatives to ensure the acquisition of competence in PNGM-related knowledge and skills, and develop strategies for assessment and accreditation.An infographic is available for this article at: http://www.annalsgastro.gr/files/journals/1/earlyview/2022/Infographic-AG6486.pdf.

Association of training standards in pediatric gastroenterology, hepatology and nutrition in European training centers with formal national recognition of the subspecialty: a survey of the ESPGHAN National Societies Network 2016-2019.

Background: This survey evaluated the effects of the recognition of pediatric gastroenterology, hepatology and nutrition (PGHN) on European PGHN training centers. Method: Standardized questionnaires were collected from training centers via the presidents/representatives of the National Societies Network of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition, from June 2016 to December 2019. Results: A total of 100 training centers from 19 countries participated in the survey: 55 from 12 countries where PGHN is formally recognized (Group 1) and 45 from 7 countries where it is not (Group 2). Training centers in Group 2 were less likely to have an integrated endoscopy suite, a written training curriculum and a training lead (P=0.059, P<0.001 and P=0.012, respectively). Trainees in Group 2 were less likely to be exposed to an adequate number of diagnostic endoscopies, while no differences were found in relation to liver biopsies. Half of the training centers in both Groups do not have dedicated beds for PGHN patients, while in 64% and 58%, respectively, trainees do not participate in on-call programs for PGHN emergencies. Research training is mandatory in 26% of the centers. The duration of training, as well as the assessment and accreditation policies, vary between countries. Conclusions: This study has revealed significant discrepancies and gaps in infrastructure and training programs, training leadership, and assessment of training and certification across European training centers in PGHN. Strategies to support the recognition of PGHN and to standardize and improve training conditions should be developed and implemented.An infographic is available for this article at: http://www.annalsgastro.gr/files/journals/1/earlyview/2022/Infographic_AG-6496.pdf.

Training in pediatric hepatology across Europe: a survey of the National Societies Network (2016-2019) of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition.

Background: The widely recognized burden of liver diseases makes training in pediatric hepatology (PH) imperative. The aim of this survey, which was part of a global survey on training in pediatric gastroenterology, hepatology and nutrition (PGHN) across Europe, was to assess the PH and liver transplantation (LT) infrastructure, staff and training programs in PGHN training centers. Method: Standardized questionnaires were collected from training centers via the presidents/representatives of the National Societies Network of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) from June 2016 to December 2019. Results: A total of 100 PGHN training centers participated in the survey (14/100 were national referral centers in PH and/or LT). Dedicated PH clinics were available in 75%, but LT clinics in only 11%. Dedicated beds for PGHN inpatients were available in 47/95 (49%) centers. Full-time or part-time specialists for PH care were available in 31/45 (69%) and 11/36 (31%) centers, respectively. Liver biopsies (LB) were performed in 93% of centers by: a PGHN specialist (35%); an interventional radiologist (26%); a pediatric surgeon (4%); or a combination of them (35%). Dividing the annual number of LBs in the centers performing LBs by the number of trainees gave a median (range) of 10 (1-125) per trainee. Transient elastography was available in 60/92 (65%) of centers. Conclusions: The survey highlighted the differences and shortcomings in PH training across Europe. ESPGHAN should take initiatives together with National Societies to ensure the acquisition of PH knowledge and skills according to the ESPGHAN curriculum.An infographic is available for this article at: http://www.annalsgastro.gr/files/journals/1/earlyview/2022/Infographic-Hepatology-training-paper.pdf.

Incidence of SARS-CoV-2 in people with cystic fibrosis in Europe between February and June 2020.

BACKGROUND: Viral infections can cause significant morbidity in cystic fibrosis (CF). The current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic could therefore have a serious impact on the health of people with CF (pwCF). METHODS: We used the 38-country European Cystic Fibrosis Society Patient Registry (ECFSPR) to collect case data about pwCF and SARS-CoV-2 infection. RESULTS: Up to 30 June 2020, 16 countries reported 130 SARS-CoV-2 cases in people with CF, yielding an incidence of 2.70/1000 pwCF. Incidence was higher in lung-transplanted patients (n=23) versus non-transplanted patients (n=107) (8.43 versus 2.36 cases/1000). Incidence was higher in pwCF versus the age-matched general population in the age groups <15, 15-24, and 25-49 years (p<0.001), with similar trends for pwCF with and without lung transplant. Compared to the general population, pwCF (regardless of transplantation status) had significantly higher rates of admission to hospital for all age groups with available data, and higher rates of intensive care, although not statistically significant. Most pwCF recovered (96.2%), however 5 died, of whom 3 were lung transplant recipients. The case fatality rate for pwCF (3.85%, 95% CI: 1.26-8.75) was non-significantly lower than that of the general population (7.46%; p=0.133). CONCLUSIONS: SARS-CoV-2 infection can result in severe illness and death for pwCF, even for younger patients and especially for lung transplant recipients. PwCF should continue to shield from infection and should be prioritized for vaccination.

Analysis of data on breastfeeding in Croatia from 2005 to 2016.

Aim To analyse available breastfeeding data in Croatia and to describe the process of gathering, collecting, recording and reporting on them to the official institutions. Methods Infant nutrition data collected at maternity wards and infant nutrition data from primary health care units during the period 2005 to 2016 have been used. Descriptive statistics was used to analyse the data and to show the trends in breastfeeding. Results More than 85% of newborns were exclusively breastfed in the maternity wards. Data on breastfeeding from primary health care showed growth in exclusive breastfeeding up to 2011, followed by a fall in 2013. From 2012, paediatric teams had the obligation to join information system (CEZIH), but electronic forms did not contain infant nutrition information. Similarly in the E-Newborn project (E-novorodence) the question on the feeding method in the application was not designated as mandatory. Conclusion The routinely collected data on breastfeeding did not allow us to draw any conclusion regarding breastfeeding trends in Croatia. In order to improve the process of gathering, recording and reporting data on breastfeeding to the proper authorities, it would be necessary to clearly align definitions, employ a uniform methodology, and upgrade the computer applications in primary health-care. Only then may the reports required for compulsory health insurance be obtained via the CEZIH, as well as the public health reports necessary to monitor preventive work in care of children's health, and monitoring public health indicators.

Expression of chemokine receptor CX3CR1 in infants with respiratory syncytial virus bronchiolitis.

Respiratory syncytial virus (RSV) glycoprotein G mimics fractalkine, a CX(3)C chemokine, which mediates chemotaxis of leukocytes expressing its receptor, CX(3)CR1. The aim of this study was to examine the relationship between RSV infection and expression of perforin and IFN-gamma in CX(3)CR1-expressing peripheral blood CD8(+) T cells. Samples were collected from infants with RSV bronchiolitis, both in the acute and convalescence phase (n = 12), and from their age- and sex-matched healthy controls (n = 15). Perforin expression and IFN-gamma secretion in CX(3)CR1(+) CD8(+) T cells were assessed by four-color flow cytometry. The NF-kappaB p50 and p65 subunit levels were also determined as markers of RSV-induced inflammation. Study results showed perforin and CX(3)CR1 expression to be significantly lower in the convalescent phase of infected infants than in healthy controls. There was no significant difference in IFN-gamma secretion and NF-kappaB binding activity between two time-points in RSV-infected infants, or when compared with healthy controls. Infants with prolonged wheezing had lower acute-phase CX(3)CR1 levels in peripheral blood. These data indicate existence of an event persisting after acute RSV infection that is able to modulate effector functions of cytotoxic T cells, and also link disease severity with CX(3)CR1 expression.

Met-enkephalin effects on histamine-induced bronchoconstriction in guinea pigs.

We investigated the effects of the neuropeptide met-enkephalin on histamine-induced bronhoconstriction in an experimental model of asthma. Classic Konzett and Rössler's method of whole body plethysmography modified by Gjuris, was applied in the study. This method represents a standard experimental model of bronchoconstriction, suitable for the evaluation of peptide effects on the histamine-induced bronchoconstriction. The results of the measurements implicate a dose-related modulatory effect of met-enkephalin on the bronchoconstrictor action of histamine. Met-enkephalin doses of 1 mg/kg and 10 mg/kg, respectively, caused statistically significant reduction of the histamine-induced bronchoconstriction. Estimated ED50 dose was 0.235 mg/kg. Further studies are needed to define practical and therapeutical use of the presented observations in respiratory pharmacology.

Correlation of clinical symptoms and laboratory findings in children with milk allergy.

Food hypersensitivities can be divided into toxic and nontoxic, and the latter can further be subdivided into immune and nonimmune hypersensitivities. Cow's milk allergy or intolerance occurs in 5-15% of infants, mostly during the first year of life, or occasionally later. The symptoms may involve different organ systems, especially the gastrointestinal system, skin, and respiratory system. For the diagnosis of cow's milk protein allergy/intolerance, double-blind, placebo-controlled food challenge has been used as a gold standard. Since the test suffers from some drawbacks, many reports have pointed to the need for novel and simpler diagnostic procedures and criteria. In our study, clinical symptoms and laboratory findings of patients with cow's milk protein allergy were compared to assess the possible correlation between particular laboratory findings, clinical picture, and the organ system predominantly involved. There were no significant differences in the levels of IgE, cow's milk protein specific IgE, eosinophilia, prick test results, rectal mucosa biopsy histology, and atopy incidence in patient families among the children with gastrointestinal, cutaneous, and combined gastrointestinal and cutaneous symptoms. Improvement in the symptoms with dietary therapy irrespective of clinical presentation and type of hypersensitivity underlying the symptoms in all these patients strongly suggests that clinical response should be a basic criterion for the diagnosis of cow's milk protein allergy.
