Conocimiento de los sanitarios de la Región de Murcia (España) sobre lactancia materna / Knowledge of health professionals from the Region of Murcia (Spain) about breastfeeding

Introducción: las bajas tasas de duración de la lactancia materna constituyen un importante problema de Salud Pública. La formación del personal sanitario es fundamental para su promoción. Objetivo: investigar sobre los conocimientos y habilidades en lactancia materna de los profesionales sanitarios de Atención Primaria (AP) y residentes de Pediatría. Material y métodos: distribución de dos cuestionarios sobre lactancia materna, dirigidos al personal sanitario de AP (Encuesta sobre conocimientos en lactancia materna, ECoLa) y residentes de Pediatría (cuestionario adaptado). Resultados: 19 encuestas de residentes y 47 de profesionales sanitarios de AP. Puntuación media de los residentes: 18,57 puntos. Puntuación media de los profesionales de AP: 19,6 puntos. El 15,8% de los residentes considera que la lactancia materna es el mejor alimento para el recién nacido, aunque la madre esté desnutrida. El 10,5% de los residentes y 59,6% de los profesionales sanitarios sabe que la “leche aguada” es la leche del principio de la toma. El 10,5% de los residentes considera que los chupetes no interfieren en la lactancia materna. El 10,5% suspende la lactancia si la madre toma amoxicilina. Un 26,3% piensa que la primera toma debe ser 3 horas después del parto. El 31,9% no conoce que la lactancia exclusiva con fórmula conlleva un riesgo incrementado de morbimortalidad. El 52,6% no recomienda lactancia materna si la madre es portadora de hepatitis B. Conclusiones: la formación de los profesionales sanitarios en lactancia materna es fundamental, los cuestionarios pueden indicar lagunas que se deben abordar mediante formación (AU)

Introduction: low rates of duration of breastfeeding are a public health problem. The training of health personnel is essential for their promotion. Objective: to investigate the knowledge and skills in breastfeeding of Primary Care health professionals and pediatric residents.Material and method: distribution of two questionnaires on breastfeeding, aimed at Primary Care health personnel (Survey on Knowledge of Breastfeeding, ECoLa) and pediatric residents (adapted questionnaire).Results: 19 resident surveys and 47 Primary Care health professionals. Residents' average score: 18,57 points. Average score of Primary Care professionals: 19,6 points. 15,8% of residents consider that breastfeeding is the best food for the newborn, even if the mother is malnourished. 10,5% of the residents and 59,6% of the Primary Care health professionals know that the 'watered down milk' is the milk from the beginning of the intake. 10,5% of residents consider that pacifiers do not interfere with breastfeeding. 10,5% stop breastfeeding if the mother takes amoxicillin. 26,3% think that the first dose should be 3 hours after delivery. 31,9% do not know that exclusive breastfeeding with formula carries an increased risk of morbidity and mortality. 52,6% do not recommend breastfeeding if the mother is a carrier of hepatitis B.Conclusions: the training of health professionals in breastfeeding is essential, the questionnaires may indicate gaps that must be addressed through training.

Molecular Diversity of Giardia duodenalis, Cryptosporidium spp. and Blastocystis sp. in Asymptomatic School Children in Leganés, Madrid (Spain).

Enteric parasites including Giardia duodenalis, Cryptosporidium spp., and to a lesser extent, Blastocystis sp. and Enterocytozoon bieneusi, are major worldwide contributors to diarrhoeal disease. Assessing their molecular frequency and diversity is important to ascertain the sources of infection, transmission dynamics, and zoonotic potential. Little molecular information is available on the genotypes of these pathogens circulating in apparently healthy children. Here, we show that asymptomatic carriage of G. duodenalis (17.4%, 95% CI: 15.5‒19.4%), Blastocystis sp. (13.0%, 95% CI: 11.4‒14.8%), and Cryptosporidium spp. (0.9%, 95% CI: 0.5‒1.5%) is common in children (1‒16 years; n = 1512) from Madrid, Spain. Our genotyping data indicate that; (i) the observed frequency and diversity of parasite genetic variants are very similar to those previously identified in Spanish clinical samples, so that the genotype alone does not predict the clinical outcome of the infection, (ii) anthroponotic transmission accounts for a large proportion of the detected cases, highlighting that good personal hygiene practices are important to minimizing the risk of infection, (iii) Blastocystis ST4 may represent a subtype of the parasite with higher pathogenic potential, and (iv) Enterocytozoon bieneusi does not represent a public health concern in healthy children.

Infecciones virales respiratorias en una cohorte de niños durante el primer año de vida y su papel en el desarrollo de sibilancias / Respiratory viral infections in a cohort of children during the first year of life and their role in the development of wheezing

Introducción: Las infecciones respiratorias virales que requieren hospitalización parecen conferir riesgo de desarrollar sibilancias recurrentes, pero existen pocos datos publicados en poblaciones no seleccionadas por tener factores de riesgo. Nuestro objetivo principal fue analizar si las infecciones respiratorias virales sintomáticas y asintomáticas, de diferente gravedad, durante el primer año de vida en una cohorte de recién nacidos, suponen un mayor riesgo de sibilancias recurrentes. Pacientes y métodos: Se incluyeron 302 recién nacidos. Se recogió aspirado nasofaríngeo a los niños cuando presentaron una infección respiratoria y de forma periódica en los controles de salud (2, 4, 6 y 12 meses). Se estudiaron 16 virus respiratorios mediante reacción en cadena de polimerasa (PCR). Resultados: Se analizaron 1.293 muestras (1.005 controles de salud y 288 infecciones respiratorias). El 30,8% de las muestras tomadas en los controles de salud fueron positivas, frente a un 77,8% en las infecciones respiratorias, p < 0,001 (OR: 3, IC 95%: 2,4-3,8). Un total de 239 (79%) lactantes tuvieron al menos una detección viral positiva durante el primer año de vida. El virus más frecuentemente identificado (71%) fue el rinovirus (RV). En 27 lactantes (11%) se detectaron sibilancias recurrentes durante su primer año de vida (2,9 DE: 1,2 episodios). El 58,3% de los lactantes cuya primera infección respiratoria requirió hospitalización desarrollaron sibilancias de repetición, frente al 8,6% de los niños cuya primera infección fue leve o asintomática, p < 0,001 (OR: 2,18; lC 95%: 1,05-4,5). Conclusiones: En nuestra serie, las infecciones respiratorias virales graves en los primeros meses de vida supusieron un factor de riesgo para desarrollar sibilancias recurrentes. No ocurrió lo mismo con las infecciones respiratorias leves (AU)

Introduction: It is known that infants with viral respiratory infections severe enough to require hospital admission have a high risk of developing recurrent wheezing. Few data have been published on unselected populations. The main aim of this study was to analyse symptomatic and asymptomatic respiratory viral infections during the first year of life in a cohort of infants, recruited at birth, and the development of recurrent wheezing. Patients and methods: A total of 302 newborns were recruited. A nasopharyngeal aspirate was taken when the patients had a respiratory infection, as well as in the visits for vaccination at 2, 4, 6, and 12 months. RT-nested PCR assays were performed to detect 16 viruses. Results: A total of 1,293 samples were analysed (1,005 healthy controls and 288 respiratory infections). Samples taken during routine check-ups were positive in 30.8% of cases, while those with respiratory infection were positive in 77.8%, P < .001 (OR: 3, 95% CI: 2.4-3.8). A total of 239 (79%) infants had at least 1 positive respiratory viral infection detected. The most frequent virus (71%) was rhinovirus (RV). Recurrent wheezing was found in 27 (11%) children during their first year of life (1.2 episodes, SD 2.9). Recurrent wheezing was present in 58.3% of patients admitted to hospital during their first viral infection, vs. 8.6% of infants when the first infection was mild or who had asymptomatic viral detection, P < .001 (OR: 2.18; 95% CI: 1.05-4.5). Conclusions: In our series, severe respiratory infections leading to hospitalisation in the first months of life are risk factors for developing wheezing, but not in the case of mild RV infections (AU)

A cluster-randomised clinical trial comparing two cardiovascular health education strategies in a child population: the Savinghearts project.

BACKGROUND: This paper describes a methodology for comparing the effects of an eduentertainment strategy involving a music concert, and a participatory class experience involving the description and making of a healthy breakfast, as educational vehicles for delivering obesity-preventing/cardiovascular health messages to children aged 7-8 years. METHODS/DESIGN: This study will involve a cluster-randomised trial with blinded assessment. The study subjects will be children aged 7-8 years of both sexes attending public primary schools in the Madrid Region. The participating schools (n=30) will be randomly assigned to one of two groups: 1) Group MC, in which the children will attend a music concert that delivers obesity-preventing/cardiovascular health messages, or 2) Group HB, in which the children will attend a participatory class providing the same information but involving the description and making of a healthy breakfast. The main outcome measured will be the increase in the number of correct answers scored on a knowledge questionnaire and in an attitudes test administered before and after the above interventions. The secondary outcome recorded will be the reduction in BMI percentile among children deemed overweight/obese prior to the interventions. The required sample size (number of children) was calculated for a comparison of proportions with an α of 0.05 and a ß of 0.20, assuming that the Group MC subjects would show values for the measured variables at least 10% higher than those recorded for the subjects of Group HB. Corrections were made for the design effect and assuming a loss to follow-up of 10%. The maximum sample size required will be 2107 children. Data will be analysed using summary measurements for each cluster, both for making estimates and for hypothesis testing. All analyses will be made on an intention-to-treat basis. DISCUSSION: The intervention providing the best results could be recommended as part of health education for young schoolchildren. TRIAL REGISTRATION: Clinicaltrials.gov: NCT01418872.
