    Introducción: El envejecimiento de la población representa uno de los retos mås importantes desde el punto de vista biosanitario. Objetivo: Valorar el estado nutricional de las personas de 65 y mås años de Cantabria. Métodos: Un total de 1605 personas fueron evaluadas por medio del MNA; a) en atención primaria (59,9% en la consulta y 4,7% en domicilios) y, b) en residencias de ancianos (35,4%). Resultados: La puntuación nutricional (PN) obtenida de la suma de los ítems del MNA fue 23,4 &plusmn; 4,1 para las mujeres y 24,4 &plusmn; 4 en los varones (p Introduction: Population ageing is a main concern under the biosanitary point of view. Aim: To assess the nutritional status of people 65 year-old and older in Cantabria (Spain) Method: A total of 1605 persons were studied by means of the MNA (Mini Nutritional Assessment); a) by primary care (59.9% in the unit, and 4.7% at home) and, b) in nursing homes (35.4%). Results: Nutritional score (NS) was 23.4 &plusmn; 4.1 for women and 24.4 &plusmn; 4 in males (p < 0.001). We emphasize the fact that 22.3% of people studied in the nursing homes were malnourished or at risk of malnutrition, compared with 14.2% of those studied at the unit, and only 3.3% of the home visited elders. The correlation between the value of the NS and the subjective estimation of nutrition status showed a high value (0.65). We emphasize the negative correlation (-0.53) between BNI value and the incidence of skin lesions. Conclusion: Our results highlight the importance of identifying malnutrition or its risk in elders in order to prevent the negative consequences of this deficiency

    International audienceThe Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique set of 5656 optical filters from a dedicated 2.552.55m telescope, JST, at the Javalambre Astrophysical Observatory. Before the arrival of the final instrument (a 1.2 Gpixels, 4.2deg2^2 field-of-view camera), the JST was equipped with an interim camera (JPAS-Pathfinder), composed of one CCD with a 0.3deg2^2 field-of-view and resolution of 0.23 arcsec pixel−1^{-1}. To demonstrate the scientific potential of J-PAS, with the JPAS-Pathfinder camera we carried out a survey on the AEGIS field (along the Extended Groth Strip), dubbed miniJPAS. We observed a total of ∌1\sim 1 deg2^2, with the 5656 J-PAS filters, which include 5454 narrow band (NB, FWHM∌145\rm{FWHM} \sim 145Angstrom) and two broader filters extending to the UV and the near-infrared, complemented by the u,g,r,iu,g,r,i SDSS broad band (BB) filters. In this paper we present the miniJPAS data set, the details of the catalogues and data access, and illustrate the scientific potential of our multi-band data. The data surpass the target depths originally planned for J-PAS, reaching magAB\rm{mag}_{\rm {AB}} between ∌22\sim 22 and 23.523.5 for the NB filters and up to 2424 for the BB filters (5σ5\sigma in a 33~arcsec aperture). The miniJPAS primary catalogue contains more than 64,00064,000 sources extracted in the rr detection band with forced photometry in all other bands. We estimate the catalogue to be complete up to r=23.6r=23.6 for point-like sources and up to r=22.7r=22.7 for extended sources. Photometric redshifts reach subpercent precision for all sources up to r=22.5r=22.5, and a precision of ∌0.3\sim 0.3% for about half of the sample. (Abridged

    International audienceThe Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will scan thousands of square degrees of the northern sky with a unique set of 56 filters using the dedicated 2.55 m Javalambre Survey Telescope (JST) at the Javalambre Astrophysical Observatory. Prior to the installation of the main camera (4.2 deg2 field-of-view with 1.2 Gpixels), the JST was equipped with the JPAS-Pathfinder, a one CCD camera with a 0.3 deg2 field-of-view and plate scale of 0.23 arcsec pixel−1. To demonstrate the scientific potential of J-PAS, the JPAS-Pathfinder camera was used to perform miniJPAS, a ∌1 deg2 survey of the AEGIS field (along the Extended Groth Strip). The field was observed with the 56 J-PAS filters, which include 54 narrow band (FWHM ∌ 145 Å) and two broader filters extending to the UV and the near-infrared, complemented by the u, g, r, i SDSS broad band filters. In this miniJPAS survey overview paper, we present the miniJPAS data set (images and catalogs), as we highlight key aspects and applications of these unique spectro-photometric data and describe how to access the public data products. The data parameters reach depths of magAB ≃ 22−23.5 in the 54 narrow band filters and up to 24 in the broader filters (5σ in a 3″ aperture). The miniJPAS primary catalog contains more than 64 000 sources detected in the r band and with matched photometry in all other bands. This catalog is 99% complete at r = 23.6 (r = 22.7) mag for point-like (extended) sources. We show that our photometric redshifts have an accuracy better than 1% for all sources up to r = 22.5, and a precision of ≀0.3% for a subset consisting of about half of the sample. On this basis, we outline several scientific applications of our data, including the study of spatially-resolved stellar populations of nearby galaxies, the analysis of the large scale structure up to z ∌ 0.9, and the detection of large numbers of clusters and groups. Sub-percent redshift precision can also be reached for quasars, allowing for the study of the large-scale structure to be pushed to z > 2. The miniJPAS survey demonstrates the capability of the J-PAS filter system to accurately characterize a broad variety of sources and paves the way for the upcoming arrival of J-PAS, which will multiply this data by three orders of magnitude.Key words: surveys / techniques: photometric / astronomical databases: miscellaneous / stars: general / galaxies: general / cosmology: observations⋆ miniJPAS data and associated value added catalogs are publicly available http://archive.cefca.es/catalogues/minijpas-pdr20191
