Childhood obesity is a global public health issue and is linked to metabolic syndrome, which increases the risk of comorbidities such as type 2 diabetes, cardiovascular diseases and cancer. Social, economic and cultural factors influence changes in nutrition and lifestyle characterized by poorer diets and reduced physical activity. This systematic review summarizes the evidence for nutritional education interventions to improve metabolic risks in children and adolescents. Systematic searches of the databases Medline (via PubMed) and Scopus were conducted following PRISMA guidelines. The risk of bias for each study was assessed following the methodology of the Cochrane Collaboration. Ten case-controlled and randomized controlled studies testing nutritional educational interventions targeting children and adolescents from the general population were eligible for inclusion. The sample size was 3915 and the age range was 7-20 years. The duration of intervention ranged from 12 weeks to 20 years. All the studies that provided data on abdominal obesity reported differences in favour of the intervention. However, data on the effects on the remaining components of metabolic syndrome remain inconclusive. These results support the role of nutritional education interventions as a strategy to reduce central adiposity and its possible unhealthy consequences in children and adolescents. Yes

The frequency of some Cystic Fibrosis (CF) Transmembrane Conductance Regulator gene (CFTR) mutations varies between populations. Genetic testing during newborn screening (NBS) for CF can identify less common mutations with low clinical expression in childhood and previously considered mild but not fully characterized, such as the mutation p.Val232Asp (c.695T > A). The aim of this study was to describe CF patients with the V232D mutation. We identify CF children with the V232D mutation detected by NBS and compare them with CF adults with this mutation whose diagnosis was prompted by clinical symptoms in the same period. We studied clinical, biochemical, spirometric, and prognostic features in both populations. NBS program tested 276,523 children during a period of 14 years (2003–2017) and identified 54 cases of CF. Six children (11%) had the V232D mutation. Over the same period, 5 adults (age 37.6 ± 16.29 years old) with symptoms of CF and this mutation were also diagnosed. Follow-up duration was mean 10.1 years for adults and mean 6.5 years for children. In the adult group, lung function was impaired at diagnosis in all patients (Forced Expiratory Volume1—FEV1—67.12% ± 13.09) and worsened in children tested during evolution (FEV1first: 113%; FEV1last: 64%). Pancreatic insufficiency was present in adult group, with recurrent pancreatitis in 1 present. Although with less clinical expression in children, V232D is associated with pulmonary and pancreatic involvement during adulthood and CF cannot be considered mild. This mutation is present in 11% of all patients diagnosed with CF in our region. Its inclusion in some NBS programs should be taken into account in order to improve the prognosis of affected children.

Hunter syndrome or mucopolysaccharidosis type II (MPSII) is a progressive multisystem X-linked lysosomal storage disease caused by mutations in the IDS gene that shows a wide spectrum of clinical symptoms and severity. Idursulfase, a specific enzyme replacement therapy (ERT) for MPSII, has been available since 2007. ERT, along with symptomatic management of patients, is fundamental for improving patient prognosis and quality of life. The aims of this study were to investigate whether Spanish pediatricians who are experts in managing the disease agreed with current international guidelines regarding MPSII patient diagnosis and follow-up; and to reach a consensus regarding which items are essential for the diagnosis, follow-up, and treatment of these patients in Spain. An advisory panel of 5 experts from the Hunter Spanish Working Group reviewed key studies, developed a questionnaire based on a modified Delphi method, sent the questionnaire to selected experts, and reviewed the responses. The final questionnaire had 83 items in the following categories: diagnosis, ERT considerations after diagnosis, Periodic assessments, and ERT considerations during follow-up. A total of 85 experts were invited to participate; 28 (35%) responded and showed a strong consensus for most items. The advisory panel decided not to perform a second Delphi round. There was strong agreement (>3.1 median value; range, 1 to 4) for 43/56 items in Diagnosis, for 4/6 items in “ERT considerations after diagnosis,” for 6/16 items in “Periodic assessments,” and for 3/5 items in “ERT considerations during follow-up.” Most responses were in agreement with international guidelines, and controversial items were discussed by the advisory panel. Based on the results, on the key studies, and on clinical experience and opinions, the panel developed and scheduled recommendations for the diagnosis and follow-up of patients with MPSII. An expert 5-person panel oversaw a Delphi survey of 28 pediatricians and reached a consensus on recommendations for the diagnosis and follow-up of MPSII patients. This document will help guide clinicians involved in the diagnosis, management, and treatment of MPSII.

Background: Significant efforts have been made to improve the nutritional support of very preterm infants. Large surveys may help to know the nutritional practices for preterm infants in neonatal units and identify if they are in line with the current guidelines. Methods: A multicentre nationwide web-based survey on clinical feeding practices in very low birth weight (VLBW) infants was conducted in tertiary neonatal hospitals that admit infants with a birth weight < 1,500 g and/or a gestational age of < 32 weeks. Results: The questionnaire was completed by 53 units (response rate, 59%). Over 90% of the units surveyed start amino-acid administration immediately after birth and more than half use novel intravenous fish oil-based lipid emulsions. Enteral nutrition is started within 24 hours of birth in 65% of units and 86% of these are medium-sized or large. Feeding volumes are increased at a rate of 10-30 ml/kg/day in > 90% of units. Monitoring of serum phosphorus was measured more frequently than albumin (p = 0.009) or triglycerides (p = 0.037), but only 28% of centres regularly measure pre-albumin as a nutritional biomarker. Human milk fortification and iron supplementation, starting at four weeks of age, are almost universal. However, only 30% of units administer 800 IU/day of vitamin D. Nearly 50% of the units discharge infants on preterm formula. Conclusion: Most Spanish neonatology units use early amino-acid supplementation and over half use novel fish oil-based lipid emulsions. Post-discharge nutrition practices and vitamin administration vary greatly. Antecedentes: se han realizado esfuerzos significativos para mejorar la nutrición en los recién nacidos muyprematuros. Las grandes encuestas pueden ayudar a conocer cuál es la nutrición que reciben los recién nacidos prematuros en las unidades neonatales e identificar si están en línea con las directrices actuales. Métodos: se llevó a cabo una encuesta multicéntrica a nivel nacional sobre las prácticas clínicas empleadas en la alimentación en los recién nacidos de muy bajo peso en hospitales de nivel III que ingresan recién nacidoscon un peso al nacer < 1.500 g y/o una edad gestacional < 32 semanas. Resultados: el cuestionario fue completado por 53 unidades neonatales (tasa de respuesta del 59%). Más del 90% de las unidades estudiadas inician la administración de aminoácidos inmediatamente después del nacimiento y más de la mitad utilizan nuevas emulsiones lipídicas intravenosas que contienen aceite de pescado. La nutrición enteral se inicia en las primeras24 horas de nacimiento en el 65% de las unidades y el 86% de ellas son medianas o grandes. El volumen de alimentación aumenta a una velocidad de 10-30 ml/kg/día en > 90% de las unidades. El fósforo sérico se monitoriza con mayor frecuencia que la albúmina (p = 0,009) o los triglicéridos (p = 0,037), pero solo el 28% de los centros miden regularmente la prealbúmina como biomarcador nutricional. La fortificación de la leche humana y la suplementación con hierro, a partir de las cuatro semanas de edad,es casi universal. Sin embargo, solo el 30% de las unidades administran 800 UI/día de vitamina D. Casi el 50% de las unidades utilizanleche de fórmula del prematuro al alta de las unidades. Conclusión: la mayoría de las unidades neonatales españolas administran precozmente los suplementos de aminoácidos y más de la mitad emplean emulsiones de lípidos a base de aceite. Hay una importante variación en las prácticas nutricionales posteriores al alta y en la administración de vitaminas.
