El modelo de la Atención Centrada en la Persona: Análisis descriptivo de una muestra de personas mayores con demencia en centros residenciales
Este análisis descriptivo tiene el objetivo de evaluar la calidad asistencial de una muestra de personas con demencia institucionalizadas usando el Dementia Care Mapping (DCM) como metodología de observación sistemática y de examinar la presencia de pautas asociadas a la psicología social maligna en las residencias observadas. Participaron en el estudio 73 personas con demencia ingresadas en residencias a largo plazo. Los resultados más relevantes apuntan a la presencia de una cultura de cuidados donde predomina la psicología social maligna y el DCM como un instrumento que permite analizar el comportamiento de las personas con demencia, aportando nuevas variables como el bienestar emocional, la diversidad ocupacional y la calidad de la interacción social. Se concluye que la implementación de un modelo de atención centrado en la persona puede incidir postivamente en el bienestar de las personas con demencia

Location, orbit and energy of a meteoroid impacting the moon during the Lunar Eclipse of January 21, 2019
During lunar eclipse of January 21, 2019 a meteoroid impacted the Moon
producing a visible light flash. The impact was witnessed by casual observers
offering an opportunity to study the phenomenon from multiple geographical
locations. We use images and videos collected by observers in 7 countries to
estimate the location, impact parameters (speed and incoming direction) and
energy of the meteoroid. Using parallax, we achieve determining the impact
location at lat. , lon. and
geocentric distance as 356553 km. After devising and applying a photo-metric
procedure for measuring flash standard magnitudes in multiple RGB images having
different exposure times, we found that the flash, had an average G-magnitude
. We use gravitational ray tracing (GRT) to
estimate the orbital properties and likely radiant of the impactor. We find
that the meteoroid impacted the moon with a speed of km/s (70%
C.L.) and at a shallow angle, degrees. Assuming a normal error
for our estimated flash brightness, educated priors for the luminous efficiency
and object density, and using the GRT-computed probability distributions of
impact speed and incoming directions, we calculate posterior probability
distributions for the kinetic energy (median = 0.8 kton), body
mass ( = 27 kg) and diameter ( = 29 cm), and crater
size ( = 9 m). If our assumptions are correct, the crater left by
the impact could be detectable by prospecting lunar probes. These results arose
from a timely collaboration between professional and amateur astronomers which
highlight the potential importance of citizen science in astronomy.Comment: 19 pages, 11 figures, 4 tables. Data and scripts available in

Proyecto DIL-D CEE: Desarrollo de políticas y estrategias de integración laboral de personas con Discapacidad en Centros Especiales de Empleo. (Informe final)
El proyecto que presentamos seguidamente tiene por objeto exponer los resultados correspondientes al cuarto año de andadura de la Cátedra UB – Fundación Adecco para la Integración Laboral de Personas con Discapacidad (http://www.ub.edu/catedrainlab/). En concreto, al informe final correspondiente al PROYECTO DIL-D desarrollado en los Centros Especiales de Empleo (CEE).
España es uno de los países de la UE con tasas más altas de desempleo entre las personas con discapacidad (32.25%) (Servicio Público de Empleo Estatal - SEPE, 2016) pese a la legislación desplegada para facilitar su inclusión, por lo que la información que elaboramos desde esta Cátedra pretendemos que sea útil para explorar nuevos caminos hacia la integración. Para ello, partimos de una perspectiva que incluye la acción conjunta de diferentes ámbitos de competencia, responsabilidad, conocimientos y experiencia de todos los agentes involucrados. En este contexto de investigación-acción presentamos el presente informe, dónde se muestran los resultados alcanzados durante este periodo de investigación, correspondiente al Proyecto DIL-D CEE.
Su principal objetivo es, en primer lugar, analizar la realidad de los CEE en España, el marco jurídico que les es de aplicación y los medios de financiación qué disponen. En segundo lugar, se analiza el grado de compromiso de diversos actores expertos en el ámbito de RRHH/RSC (gerentes, directores, propietarios, y presidentes de asociaciones de Centros Especiales de Empleo) en materia de integración laboral de personas con discapacidad. Se realiza un análisis de los retos, oportunidades, amenazas, y debilidades que se perciben en el presente y el futuro de los CEE
Evolution of genes and repeats in the Nimrod superfamily
The recently identified Nimrod superfamily is characterized by the presence of a special type of EGF repeat, the NIM repeat, located right after a typical CCXGY/W amino acid motif. On the basis of structural features, nimrod genes can be divided into three types. The proteins encoded by Draper-type genes have an EMI domain at the N-terminal part and only one copy of the NIM motif, followed by a variable number of EGF-like repeats. The products of Nimrod B-type and Nimrod C-type genes (including the eater gene) have different kinds of N-terminal domains, and lack EGF-like repeats but contain a variable number of NIM repeats. Draper and Nimrod C-type (but not Nimrod B-type) proteins carry a transmembrane domain. Several members of the superfamily were claimed to function as receptors in phagocytosis and/or binding of bacteria, which indicates an important role in the cellular immunity and the elimination of apoptotic cells. In this paper, the evolution of the Nimrod superfamily is studied with various methods on the level of genes and repeats. A hypothesis is presented in which the NIM repeat, along with the EMI domain, emerged by structural reorganizations at the end of an EGF-like repeat chain, suggesting a mechanism for the formation of novel types of repeats. The analyses revealed diverse evolutionary patterns in the sequences containing multiple NIM repeats. Although in the Nimrod B and Nimrod C proteins show characteristics of independent evolution, many internal NIM repeats in Eater sequences seem to have undergone concerted evolution. An analysis of the nimrod genes has been performed using phylogenetic and other methods and an evolutionary scenario of the origin and diversification of the Nimrod superfamily is proposed. Our study presents an intriguing example how the evolution of multigene families may contribute to the complexity of the innate immune response
Highly fluorinated erbium(III) complexes for emission in the C-band
Two highly fluorinated Er3+ complexes with three 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate (fod) groups and either bipyridine (bipy) or bathophenantholine (bath) as the ancillary ligand emitting at the C-band (third communication window for fiber transmission) are presented. These complexes are the result of a design process aimed at decreasing the vibrational quenching from high frequency oscillators. The structure of [Er(fod)3(bipy)] has been elucidated by single-crystal X-ray diffraction, while Sparkle/PM6 and Sparkle/PM7 semi-empirical calculations have been used to model the ground state geometry for [Er(fod)3(bath)]. Photoluminescence studies confirm sensitization of the Er3+ ions by antenna effect, leading to NIR emission at 1.53 μm. This energy transfer proves to be more efficient for [Er(fod)3(bath)] as a result of the bulkier and more rigid structure of bath diimide. The good thermal stability of the materials up to over 200 °C allows envisaging their use in erbium-doped waveguides, NIR-OLEDs or other optoelectronic devices
Chagas Disease among the Latin American Adult population attending in a primary care center in Barcelona, Spain
Background/Aims: The epidemiology of Chagas disease, until recently confined to areas of continental Latin America, has undergone considerable changes in recent decades due to migration to other parts of the world, including Spain. We studied the prevalence of Chagas disease in Latin American patients treated at a health center in Barcelona and evaluated its clinical phase. We make some recommendations for screening for the disease. Methodology/Principal Findings: We performed an observational, cross-sectional prevalence study by means of an immunochromatographic test screening of all continental Latin American patients over the age of 14 years visiting the health centre from October 2007 to October 2009. The diagnosis was confirmed by serological methods: conventional in-house ELISA (cELISA), a commercial kit (rELISA) and ELISA using T cruzi lysate (Ortho-Clinical Diagnostics) (oELISA). Of 766 patients studied, 22 were diagnosed with T. cruzi infection, showing a prevalence of 2.87% (95% CI, 1.6-4.12%). Of the infected patients, 45.45% men and 54.55% women, 21 were from Bolivia, showing a prevalence in the Bolivian subgroup (n = 127) of 16.53% (95% CI, 9.6-23.39%). All the infected patients were in a chronic phase of Chagas disease: 81% with the indeterminate form, 9.5% with the cardiac form and 9.5% with the cardiodigestive form. All patients infected with T. cruzi had heard of Chagas disease in their country of origin, 82% knew someone affected, and 77% had a significant history of living in adobe houses in rural areas. Conclusions: We found a high prevalence of T. cruzi infection in immigrants from Bolivia. Detection of T. cruzi¿infected persons by screening programs in non-endemic countries would control non-vectorial transmission and would benefit the persons affected, public health and national health systems
