Ingesta y fuentes de sodio en un colectivo de escolares españoles y su relación con distintos parámetros sanitarios y dietéticos

El sodio es un mineral esencial para la vida por sus numerosas funciones en el organismo. Sin embargo, la ingesta excesiva de este mineral se ha relacionado con la aparición de marcadores tempranos de riesgo cardiometabólico incluyendo mayores cifras de tensión arterial, e indicadores de obesidad y obesidad central ya en edades tempranas. La OMS (Organización Mundial de la Salud) en el año 2003 estableció como objetivo disminuir la ingesta de sal a menos de 5 g/día en adultos, objetivo posteriormente ampliado a la población infantil considerándose que debía adaptarse a su ingesta energética. Esta referencia es superada por la población de los países europeos, incluida España, en la que se ha observado que la ingesta de sal es excesiva en población adulta a través de la medición del sodio excretado en orina de 24 horas (método de referencia para medir la ingesta de sodio o sal a nivel poblacional). Sin embargo, en población infantil no hay estudios recientes que hayan analizado la excreción del mineral en orina de 24 horas y/o que procedan de varias regiones españolas incluyendo ambos sexos..

Usual Dietary Intake, Nutritional Adequacy and Food Sources of Calcium, Phosphorus, Magnesium and Vitamin D of Spanish Children Aged One to <10 Years. Findings from the EsNuPI Study †

The authors would like to thank IPN for its support and technical advice.Bone problems in the population begin to be establish in childhood. The present study aims to assess the usual calcium, phosphorus, magnesium, and vitamin D intakes, along with the food sources of these nutrients, in Spanish children participating in the EsNuPI (Estudio Nutricional en Población Infantil Española) study. Two 24 h dietary recalls were applied to 1448 children (1 to <10 years) divided into two sub-samples: one reference sample (RS) of the general population [n = 707] and another sample which exclusively included children consuming enriched or fortified milks, here called “adapted milks” (AMS) [n = 741]. Estimation of the usual intake shows that nutrient intake increased with age for all nutrients except vitamin D. Using as reference the Dietary Reference Values from the European Food Safety Authority (EFSA), calcium and magnesium intakes were found to be below the average requirement (AR) and adequate intake (AI), respectively, in a considerable percentage of children. Furthermore, phosphorus exceeded the AI in 100% of individuals and vitamin D was lower than the AI in almost all children studied. The results were very similar when considering only plausible reporters. When analyzing the food sources of the nutrients studied, milk and dairy products contributed the most to calcium, phosphorus, magnesium, and vitamin D. Other sources of calcium were cereals and vegetables; for phosphorus: meat, meat products, and cereals; for magnesium: cereals and fruits; and, for vitamin D: fish and eggs. These results highlight the desirability of improving the intake concerning these nutrients, which are involved in bone and metabolic health in children. The AMS group appeared to contribute better to the adequacy of those nutrients than the RS group, but both still need further improvement. Of special interest are the results of vitamin D intakes, which were significantly higher in the AMS group (although still below the AI), independent of age.Instituto Puleva de Nutricion (IPN

The relationship between physical activity, apolipoprotein e ϵ4 carriage, and brain health

Background: Neuronal hyperexcitability and hypersynchrony have been described as key features of neurophysiological dysfunctions in the Alzheimer's disease (AD) continuum. Conversely, physical activity (PA) has been associated with improved brain health and reduced AD risk. However, there is controversy regarding whether AD genetic risk (in terms of APOE ϵ4 carriage) modulates these relationships. The utilization of multiple outcome measures within one sample may strengthen our understanding of this complex phenomenon. Method: The relationship between PA and functional connectivity (FC) was examined in a sample of 107 healthy older adults using magnetoencephalography. Additionally, we explored whether ϵ4 carriage modulates this association. The correlation between FC and brain structural integrity, cognition, and mood was also investigated. Results: A relationship between higher PA and decreased FC (hyposynchrony) in the left temporal lobe was observed among all individuals (across the whole sample, in ϵ4 carriers, and in ϵ4 non-carriers), but its effects manifest differently according to genetic risk. In ϵ4 carriers, we report an association between this region-specific FC profile and preserved brain structure (greater gray matter volumes and higher integrity of white matter tracts). In this group, decreased FC also correlated with reduced anxiety levels. In ϵ4 non-carriers, this profile is associated with improved cognition (working and episodic memory). Conclusions: PA could mitigate the increase in FC (hypersynchronization) that characterizes preclinical AD, being beneficial for all individuals, especially ϵ4 carriers.This study was funded by the Spanish Ministry of Economy and Competitiveness under the Grant PSI2015-68793-C3-1-R [D601] and by the project B2017/BMD-3760 from NEUROCENTRO.

Age and APOE genotype affect the relationship between objectively measured physical activity and power in the alpha band, a marker of brain disease

BACKGROUND: Electrophysiological studies show that reductions in power within the alpha band are associated with the Alzheimer\u27s disease (AD) continuum. Physical activity (PA) is a protective factor that has proved to reduce AD risk and pathological brain burden. Previous research has confirmed that exercise increases power in the alpha range. However, little is known regarding whether other non-modifiable risk factors for AD, such as increased age or APOE ε4 carriage, alter the association between PA and power in the alpha band. METHODS: The relationship between PA and alpha band power was examined in a sample of 113 healthy adults using magnetoencephalography. Additionally, we explored whether ε4 carriage and age modulate this association. The correlations between alpha power and gray matter volumes and cognition were also investigated. RESULTS: We detected a parieto-occipital cluster in which PA positively correlated with alpha power. The association between PA and alpha power remained following stratification of the cohort by genotype. Younger and older adults were investigated separately, and only younger adults exhibited a positive relationship between PA and alpha power. Interestingly, when four groups were created based on age (younger-older adult) and APOE (E3/E3-E3/E4), only younger E3/E3 (least predicted risk) and older E3/E4 (greatest predicted risk) had associations between greater alpha power and higher PA. Among older E3/E4, greater alpha power in these regions was associated with improved memory and preserved brain structure. CONCLUSION: PA could protect against the slowing of brain activity that characterizes the AD continuum, where it is of benefit for all individuals, especially E3/E4 older adults

Científicas españolas: un mundo por descubrir

Objetivos: La Unión Europea sugiere, entre otros puntos, que la formación universitaria sea complementada con los avances que se vayan produciendo en la investigación científica y, además, pone un especial énfasis en la digitalización de contenidos y en la difusión a través de internet en la Educación Superior. Por ello, el objetivo del proyecto llevado a cabo fue realizar una actividad en la que los alumnos entrevistaran a una mujer científica española que trabajara en alguno de los temas estudiados en clases e ir creando un blog, vinculado a Facebook, con las entrevistas realizadas. De esta forma, además de dar visibilidad a las científicas de nuestro país, ya que en muchos casos la mujer está infravalorada por la sociedad en el ámbito científico, se pretendía conseguir la participación activa del alumnado y favorecer y fomentar su aprendizaje activo, desarrollar la capacidad del alumno de profundizar en un tema de investigación y de plantearse y de que tomaran conciencia del relevante nivel científico que existe en nuestro país y, en concreto, de la importancia que tienen las mujeres. Metodología: Se propuso la actividad a alumnos de 5 Grados diferentes (Farmacia, Doble Grado de Nutrición y Dietética, Ciencia y Tecnología de los Alimentos, Terapia Ocupacional y Óptica y Optometría). Los alumnos interesados en participar formaron grupos de trabajo y eligieron el tema sobre el que querían trabajar del listado propuesto por los profesores. Buscaron una mujer científica española de reconocido prestigio que trabajara en el tema elegido y, después de comunicárselo al profesor, se pusieron en contacto con ella para solicitarles la realización de la entrevista. Una vez que esta accedía a su realización, los alumnos prepararon un dossier de preguntas basándose en los trabajos publicados de la misma, y, tras ser supervisado y corregido por el profesor, eran formuladas a la científica elegida. Una vez realizada la entrevista, los alumnos redactaron un artículo y tras su revisión por el profesor, se hacía público en el blog. Para dar mayor visibilidad al blog, se creó una cuenta abierta de Facebook en la que se iba vinculando el mismo. Al final de todo el proceso se realizó una valoración de la actividad global por parte de los alumnos mediante una encuesta de opinión tipo Likert. Resultados: Se ofertó la actividad a 581 alumnos y participaron 195 (33,6%). Con la actividad propuesta se ha conseguido la participación activa de un porcentaje considerable del alumnado, destacando en los Grados de CYTA (78,4%), Doble Grado de Farmacia y Nutrición (72,3%) y Farmacia (24,1%). Dentro de los que participaron en la actividad, el porcentaje de aprobados fue mayor que el de suspensos (78 vs. 22%; p<0,05, respectivamente). Por otra parte, la valoración otorgada a la actividad fue bastante buena (3,8 sobre 5 puntos), aunque muchos estudiantes manifestaron que les llevó bastante tiempo su realización. Por último, según los alumnos, la actividad les hizo tomar conciencia del alto nivel científico de muchas científicas españolas (4,5 puntos sobre 5)
