Deficiencia de vitamina D en niños aragoneses sanos

Introducción: la principal acción de la vitamina D es mantener la concentración de calcio y fósforo dentro del rango fisiológico permitiendo el metabolismo normal y la mineralización ósea. Últimamente, se han descrito receptores de vitamina D en muchos tejidos y se ha relacionado la deficiencia de la vitamina D no solo con raquitismo y osteomalacia, sino también con mayor riesgo de diabetes, obesidad, enfermedades cardiovasculares, oncológicas, infecciosas y autoinmunes. Objetivo: el objetivo del estudio fue conocer la concentración de vitamina D en una población pediátrica sana y comprobar sus factores influyentes, así como analizar la situación actual de profilaxis de vitamina D y valorar la eficacia de las recomendaciones actuales. Métodos: se seleccionaron 107 pacientes sanos, de edades comprendidas entre uno y 15 años, que precisaron una analítica sanguínea como preoperatorio de cirugía menor, cuya patología no influyera en los parámetros del estudio. Resultados: la muestra estaba constituida en un 78, 5% por varones y presentaba una media de edad de 7, 17 ± 3, 79 años. La concentración media de vitamina D fue de 26, 07 ± 7, 11 ng/ml y hasta un 72, 9% presentaba niveles insuficientes. Se dividió la muestra en dos grupos: pacientes con hipovitaminosis D y pacientes con niveles óptimos de vitamina D. Se observó en el grupo con hipovitaminosis un predominio de varones, mayor índice de masa corporal y la presencia de fototipos extremos así como provenientes de padres inmigrantes. También presentaban mayor riesgo de hipovitaminosis los que no habían realizado profilaxis durante el primer año de vida. Conclusiones: se pone de manifiesto el alto porcentaje de población infantil sana con déficit de vitamina D y que las recomendaciones actuales de profilaxis no son llevadas a cabo por la población como recomiendan las guías actuales Background: the main action of vitamin D is to maintain the concentration of calcium and phosphorus within the physiological range, allowing normal metabolism and bone mineralization. Vitamin D receptors have recently been described in many tissues, therefore vitamin D deficiency has been related not only to rickets, but also to increased risk of diabetes, obesity, cardiovascular, oncological, infectious and autoimmune diseases. Objective: the aim of the study was to know the vitamin D concentration in a healthy pediatric population and to verify its influential factors, as well as to analyze the current situation of vitamin D prophylaxis and to evaluate the effectiveness of current recommendations. Methods: one hundred and seven healthy patients aged between one and 15 years were selected, who required a blood test as a preoperative minor surgery and whose pathology did not influence the parameters of the study. Results: the sample analyzed had a total of 78.5% males and a mean age of 7.17 ± 3.79 years. Mean values of vitamin D were 26.07 ± 7.11 ng/ml; up to 72.9% had insufficient levels. The sample was divided into two groups: patients with hypovitaminosis D and patients with optimal vitamin D levels. A predominance of males with a higher body mass index, from immigrant parents, and the presence of extreme phototypes were observed in the hypovitaminosis group. There was also a higher risk of hypovitaminosis in those who had not performed prophylaxis during the first year of life. Conclusions: the high percentage of healthy children with vitamin D deficiency is evident, and current recommendations for prophylaxis are not carried out by the population as recommended by current guidelines

Effectiveness of an mHealth intervention combining a smartphone app and smart band on body composition in an overweight and obese population: Randomized controlled trial (EVIDENT 3 study)

Background: Mobile health (mHealth) is currently among the supporting elements that may contribute to an improvement in health markers by helping people adopt healthier lifestyles. mHealth interventions have been widely reported to achieve greater weight loss than other approaches, but their effect on body composition remains unclear. Objective: This study aimed to assess the short-term (3 months) effectiveness of a mobile app and a smart band for losing weight and changing body composition in sedentary Spanish adults who are overweight or obese. Methods: A randomized controlled, multicenter clinical trial was conducted involving the participation of 440 subjects from primary care centers, with 231 subjects in the intervention group (IG; counselling with smartphone app and smart band) and 209 in the control group (CG; counselling only). Both groups were counselled about healthy diet and physical activity. For the 3-month intervention period, the IG was trained to use a smartphone app that involved self-monitoring and tailored feedback, as well as a smart band that recorded daily physical activity (Mi Band 2, Xiaomi). Body composition was measured using the InBody 230 bioimpedance device (InBody Co., Ltd), and physical activity was measured using the International Physical Activity Questionnaire. Results: The mHealth intervention produced a greater loss of body weight (–1.97 kg, 95% CI –2.39 to –1.54) relative to standard counselling at 3 months (–1.13 kg, 95% CI –1.56 to –0.69). Comparing groups, the IG achieved a weight loss of 0.84 kg more than the CG at 3 months. The IG showed a decrease in body fat mass (BFM; –1.84 kg, 95% CI –2.48 to –1.20), percentage of body fat (PBF; –1.22%, 95% CI –1.82% to 0.62%), and BMI (–0.77 kg/m2, 95% CI –0.96 to 0.57). No significant changes were observed in any of these parameters in men; among women, there was a significant decrease in BMI in the IG compared with the CG. When subjects were grouped according to baseline BMI, the overweight group experienced a change in BFM of –1.18 kg (95% CI –2.30 to –0.06) and BMI of –0.47 kg/m2 (95% CI –0.80 to –0.13), whereas the obese group only experienced a change in BMI of –0.53 kg/m2 (95% CI –0.86 to –0.19). When the data were analyzed according to physical activity, the moderate-vigorous physical activity group showed significant changes in BFM of –1.03 kg (95% CI –1.74 to –0.33), PBF of –0.76% (95% CI –1.32% to –0.20%), and BMI of –0.5 kg/m2 (95% CI –0.83 to –0.19). Conclusions: The results from this multicenter, randomized controlled clinical trial study show that compared with standard counselling alone, adding a self-reported app and a smart band obtained beneficial results in terms of weight loss and a reduction in BFM and PBF in female subjects with a BMI less than 30 kg/m2 and a moderate-vigorous physical activity level. Nevertheless, further studies are needed to ensure that this profile benefits more than others from this intervention and to investigate modifications of this intervention to achieve a global effect

Sistemas de protección y detección de contagios en los pediatras de atención primaria en la epidemia por COVID-19

Introducción: durante la pandemia de COVID-19, el uso de equipos y dispositivos de protección por parte de los profesionales es fundamental para evitar la transmisión de la infección en el colectivo de sanitarios. Material y métodos: el Grupo Laboral-Profesional de la Asociación Española de Pediatría de Atención Primaria (AEPap) ha realizado una encuesta a los vocales autonómicos de la AEPap para conocer la disponibilidad que han tenido los pediatras de Atención Primaria (PAP) de sistemas de protección frente a la enfermedad, y las pruebas diagnósticas realizadas para el diagnóstico de los contagios de los PAP. Resultados: en marzo de 2020, solo en el 32% de las comunidades autónomas (CC. AA.), los pediatras tenían sistemas de protección adecuados. En abril ascendió al 70%. En todas las CC. AA. se han registrado casos de PAP enfermos, aunque es difícil cuantificar el número de afectados. De las que tenemos datos, sumando el número de pediatras enfermos conocido, más test de reacción en cadena de la polimerasa (PCR) positivo, los que han estado en aislamiento y los ingresados, la cifra asciende al 7,65% de la cifra total de PAP. Los test rápidos serológicos o PCR o ambos se han realizado en seis comunidades los últimos días de abril y en otras seis los primeros días de mayo. Entre las CC. AA. de las que hay información, Aragón es la única comunidad en la que no se ha realizado test. Se ha correlacionado la disponibilidad de los sistemas de protección y el gasto sanitario. Conclusiones: los sistemas de protección han sido insuficientes. Las CC. AA. con mayor gasto sanitario han contado más precozmente con sistemas de protección adecuados. Han resultado infectados PAP en todas las comunidades autónomas, especialmente en Madrid, Castilla y León y Comunidad Valenciana. La detección de profesionales afectos por la infección ha sido tardía

Volume I. Introduction to DUNE

The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. This TDR is intended to justify the technical choices for the far detector that flow down from the high-level physics goals through requirements at all levels of the Project. Volume I contains an executive summary that introduces the DUNE science program, the far detector and the strategy for its modular designs, and the organization and management of the Project. The remainder of Volume I provides more detail on the science program that drives the choice of detector technologies and on the technologies themselves. It also introduces the designs for the DUNE near detector and the DUNE computing model, for which DUNE is planning design reports. Volume II of this TDR describes DUNE\u27s physics program in detail. Volume III describes the technical coordination required for the far detector design, construction, installation, and integration, and its organizational structure. Volume IV describes the single-phase far detector technology. A planned Volume V will describe the dual-phase technology
