Breastfeeding and Inborn Errors of Amino Acid and Protein Metabolism: A Spreadsheet to Calculate Optimal Intake of Human Milk and Disease-Specific Formulas.

Human milk (HM) offers important nutritional benefits. However, except for phenylketonuria (PKU), there are little data on optimal levels of consumption of HM and a special formula free of disease-related amino acids (SF-AA) in infants with inborn errors of metabolism of amino acids and proteins (IEM-AA-P). We designed a spreadsheet to calculate the amounts of SF-AA and HM required to cover amino acid, protein, and energy needs in patients with the nine main IEM-AA-P in infants aged under 6 months.

Lactose and Galactose Content in Spanish Cheeses: Usefulness in the Dietary Treatment of Patients with Galactosaemia.

In galactosaemia, a strict galactose-free diet is necessary to prevent or resolve acute symptoms in infants. However, because the body produces up to 10 times more galactose than is found in a galactose-restricted diet, excessively restrictive diets should be avoided in children and adults to prevent nutritional deficiencies. Since cheese is a nutritional source of the calcium necessary for bone health, the latest international guidelines on the management of classical galactosaemia (2017) allow the consumption of cured cheeses with less than 25 mg of galactose/100 g and recommend that each country verifies the adequacy of the cheeses, since most mature cheeses do not always have a lower galactose content.

Consequences of COVID-19 pandemic over acute bronchiolitis hospitalizations in the center and east of Spain.

Introduction: Non-pharmaceutical interventions that have been implemented in southern hemisphere countries because of COVID-19 pandemic declaration in March 2020, have evidenced some unexpected changes in the way of spreading of many other viruses. This study as a part of ECEALHBA's Project, reports the consequences of COVID-19 pandemic over 2020-2021 bronchiolitis epidemic period in the Central and Eastern regions of Spain.

Method: Multicenter, observational, descriptive and ambispective study of admitted infants with the diagnosis of bronchiolitis in 16 Spanish hospitals involved in the investigation project.

Usefulness of complementary test in the study of patients with chronic abdominal pain.

Introduction: Chronic abdominal pain (CAP) in children is a symptom that frequently leads to a visit to the paediatrician, which affects family life and occasionally requires the need to perform diagnostic studies (DS). The objective was to carry out a qualitative, quantitative, and economic analysis on the tests requested.

Material And Methods: An observational, prospective and multicentre study was conducted that included children between 4-15 years old affected by CAP.

[Diagnosis of celiac disease in clinical practice: present and future].

Introduction: European guidelines for the diagnosis of celiac disease (CD) have been updated in 2020. The primary objective was to review the compliance with the diagnostic criteria for CD, according to ESPGHAN 2012. Secondarily, to describe the clinical characteristics of the patients and to assess the changes that would be implied by the application of the new 2020 criteria.

Assessment of nutritional status and bone health in neurologically impaired children: a challenge in pediatric clinical practice.

Introduction: neurologically impaired children frequently experience nutritional disorders and bone health complications. Our aim was firstly to analyze a method to interpret bone mineral density (BMD) accurately in neurologically impaired children. Secondly, to determine its relationship with the nutritional status and micronutrient levels in order to identify which factors are associated with low BMD.

[Epstein-Barr virus primary infection in healthy children].

Introduction: The aim of this study is to assess epidemiological, clinical and laboratory characteristics of primary infection by Epstein-Barr virus (EBV) in children without previous diagnosis of any immune disease and its relationship with clinical presentation.

Patients And Methods: A retrospective study was conducted on all children from 0 to 15 years with IgM against viral capsid of EBV positive or indeterminate during a 22 month period. Epidemiological, clinical and laboratory data were analysed and compared between typical (mononucleosis syndrome) and non-typical clinical symptoms.

[Anti-tissue transglutaminase antibodies not related to gluten intake].

Introduction: Anti-tissue transglutaminase antibodies (tTG) have high specificity for coeliac disease (CD). However, positive anti-tTG antibodies have been described in non-coeliac patients. Aim To assess positive anti-tTG antibodies not related to gluten intake.
