Estimación de la mortalidad atribuible a gripe estacional en España. Temporadas 1980-2008.

El objetivo de este estudio es estimar los excesos de mortalidad atribuibles a gripe estacional por grupos de edad, durante el período 1980-2008 en España, según las causas de mortalidad por "gripe y neumonía", "circulatorias y respiratorias" o "todas las causas". Se aplicó un modelo de regresión cíclica (Serfling modificado) a los datos de mortalidad obtenidos del Instituto Nacional de Estadística (INE), estimándose los excesos de defunciones mensuales atribuidas a gripe en períodos de circulación viral, con respecto a un nivel basal de mortalidad esperada en ausencia de actividad gripal, para los grupos de causas y de edad planteados. Para todas las temporadas y grupos de causas, más del 90% de los excesos de defunciones atribuibles a gripe estacional se produjeron en el grupo de mayores de 64 años. Se estimó una tasa media anual de excesos de defunciones por gripe y neumonía de 2,68 (IC 95%: 2,65; 2,71) defunciones/100.000 habitantes

A Case Study of available methodology for the identification of Vulnerable Ecosystems/Habitats in bottom deep-sea fisheries: Possibilities to apply this method in the NAFO Regulatory Area in order to select Marine Protected Areas

Information is critical to Ecosystem Approach and to research about Vulnerable Marine Ecosystems/Habitats (VME/Hs), fishing impacts on habitats and ad-hoc management measures are high-priority. Therefore, this paper presents the ECOVUL/ARPA Interdisciplinary Approach, a case study of methodology for the identification of VME/Hs in order to advise on conservation measures such as marine protected areas (MPAs). By means of an interactive process involving Conventional Fisheries Science, Geomorphology, Sedimentology and Benthic Ecology, the methodology developed under the ECOVUL/ARPA project, has been useful in order to contribute to define practical criteria to the identification of VME/Hs, to improve the knowledge about VME/Hs distribution and the adverse impacts of bottom trawl fisheries and to produce high quality advice on habitat protection. Applying an interdisciplinary approach, the project identified the deep-water bottom trawl fishery footprint on the Hatton Bank Western slope (NEAFC Regulatory Area), mapped the main fishing grounds and related seabed habitats and studied the interactions between fishing and cold-water corals. This approach was used to suggest, with high level of precision, the spatial limits of an area closed to bottom fishing, as an essential conservation measure to protect the cold-water corals in the framework of the Ecosystem Approach to Fisheries management. We present here the methods used, the main results obtained and discuss on the utility of this approach and the possibilities to apply it in the NAFO Regulatory Area, with the aim to advise on measures for reducing the interactions of bottom fishing with sensitive high-seas habitats and to contribute to implement the UNGA recommendations about habitat conservation

Safety of switching from intravenous to subcutaneous rituximab during first-line treatment of patients with non-Hodgkin lymphoma: the Spanish population of the MabRella study

Rituximab is a standard treatment for non-Hodgkin diffuse large B-cell (DLBCL) and follicular (FL) lymphomas. A subcutaneous formulation was developed to improve the resource use of intravenous rituximab, with comparable efficacy and safety profiles except for increased administration-related reactions (ARRs). MabRella was a phase IIIb trial to assess the safety of switching from intravenous to subcutaneous administration of rituximab during first-line induction/maintenance for DLBCL or FL, focusing on ARRs. Efficacy, satisfaction and quality of life were also assessed. Patients received subcutaneous rituximab plus standard induction chemotherapy for DLBCL or FL for 4–7 cycles, and/or every 2 months maintenance monotherapy for FL for 6–12 cycles. The study included 140 patients: DLBCL, n = 29; FL, n = 111. Ninety-five percent of patients experienced adverse events, reaching grade ≥3 in 38 6% and were serious in 30 0%. AARs occurred in 48 6%, mostly (84 9%) at the injection site, with only 2 1% of patients reaching grade 3. The end-of-induction complete/unconfirmed complete response rate was 69 6%. After a median follow-up of 33 5 months, median disease-/event-/progression-free and overall survivals were not attained. The Rituximab Administration Satisfaction Questionnaire showed improvements in overall satisfaction and the EuroQoL-5D a good quality-of-life perception at induction/maintenance end. Therefore, switching to subcutaneous rituximab showed no new safety issues and maintained efficacy with improved satisfaction and quality of life

Usual dietary intake, nutritional adequacy and food sources of calcium, phosphorus, magnesium and vitamin D of spanish children aged one to dagger

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

Specialized proresolving mediators protect against experimental autoimmune myocarditis by modulating Ca2+ handling and NRF2 activation

Specialized proresolving mediators and, in particular, 5(S), (6)R, 7-trihydroxyheptanoic acid methyl ester (BML-111) emerge as new therapeutic tools to prevent cardiac dysfunction and deleterious cardiac damage associated with myocarditis progression. The cardioprotective role of BML-111 is mainly caused by the prevention of increased oxidative stress and nuclear factor erythroid-derived 2-like 2 (NRF2) down-regulation induced by myocarditis. At the molecular level, BML-111 activates NRF2 signaling, which prevents sarcoplasmic reticulum–adenosine triphosphatase 2A down-regulation and Ca2+ mishandling, and attenuates the cardiac dysfunction and tissue damage induced by myocarditis.This work was supported by the Spanish Ministry of Economy and Competitiveness and the European Regional Development Fund (SAF-2017-84777R), Instituto de Salud Carlos III (ISCIII) (PI17/01093, PI17/01344, and PI20/01482), Sociedad Española de Cardiología, Proyecto Traslacional 2019 and Asociación del Ritmo Cardiaco (SEC, España), Proyecto Asociación Insuficiencia Cardiaca (Trasplante Cardiaco) 2020, Fondo Europeo de Desarrollo Regional, Fondo Social Europeo, and CIBERCV, a network funded by ISCIII, Spanish Ministry of Science, Innovation and Universities (PGC2018-097019-B-I00), Ministerio de Economía, Industria y Competitividad/Agencia Estatal de Investigación 10.13039/501100011033 PID2020-113238RB-I00, PID2019-105600RB-I00, the Instituto de Salud Carlos III (Fondo de Investigación Sanitaria grant PRB3 [PT17/0019/0003-ISCIII-SGEFI/ERDF, ProteoRed]), and “la Caixa” Foundation (project code HR17-00247).

Miniatures from domestic contexts in Iron age Iberia

This article reviews a set of miniatures from domestic contexts in Iron Age eastern Iberia, and interprets them in terms of their role in forging social personae. After an introduction to the historical case under consideration, the miniatures are described in terms of their typology and their contexts of provenance are outlined. Though not abundant, they tend to occur in central places in the landscape; specifically, they are often found in houses of the powerful. The vast majority are miniatures of pottery and tools, though some miniature weapons are recorded. We contend that these objects were used as a means of enculturation and for the learning of values and norms. It is no coincidence that they emerge in the archaeological record of Iron Age Iberia at the same time as the rise of a social structure based on hereditary power

Loss of ATM kinase activity leads to embryonic lethality in mice

Ataxia telangiectasia (A-T) mutated (ATM) is a key deoxyribonucleic acid (DNA) damage signaling kinase that regulates DNA repair, cell cycle checkpoints, and apoptosis. The majority of patients with A-T, a cancer-prone neurodegenerative disease, present with null mutations in Atm. To determine whether the functions of ATM are mediated solely by its kinase activity, we generated two mouse models containing single, catalytically inactivating point mutations in Atm. In this paper, we show that, in contrast to Atm-null mice, both D2899A and Q2740P mutations cause early embryonic lethality in mice, without displaying dominant-negative interfering activity. Using conditional deletion, we find that the D2899A mutation in adult mice behaves largely similar to Atm-null cells but shows greater deficiency in homologous recombination (HR) as measured by hypersensitivity to poly (adenosine diphosphate-ribose) polymerase inhibition and increased genomic instability. These results may explain why missense mutations with no detectable kinase activity are rarely found in patients with classical A-T. We propose that ATM kinase-inactive missense mutations, unless otherwise compensated for, interfere with HR during embryogenesis

Global diversity and biogeography of deep-sea pelagic prokaryotes

The deep-sea is the largest biome of the biosphere, and contains more than half of the whole ocean/'s microbes. Uncovering their general patterns of diversity and community structure at a global scale remains a great challenge, as only fragmentary information of deep-sea microbial diversity exists based on regional-scale studies. Here we report the first globally comprehensive survey of the prokaryotic communities inhabiting the bathypelagic ocean using high-throughput sequencing of the 16S rRNA gene. This work identifies the dominant prokaryotes in the pelagic deep ocean and reveals that 50{\%} of the operational taxonomic units (OTUs) belong to previously unknown prokaryotic taxa, most of which are rare and appear in just a few samples. We show that whereas the local richness of communities is comparable to that observed in previous regional studies, the global pool of prokaryotic taxa detected is modest (\~{}3600 OTUs), as a high proportion of OTUs are shared among samples. The water masses appear to act as clear drivers of the geographical distribution of both particle-attached and free-living prokaryotes. In addition, we show that the deep-oceanic basins in which the bathypelagic realm is divided contain different particle-attached (but not free-living) microbial communities. The combination of the aging of the water masses and a lack of complete dispersal are identified as the main drivers for this biogeographical pattern. All together, we identify the potential of the deep ocean as a reservoir of still unknown biological diversity with a higher degree of spatial complexity than hitherto considered.En prensa8,951

Coronal voids and their magnetic nature

Context: Extreme ultraviolet (EUV) observations of the quiet solar atmosphere reveal extended regions of weak emission compared to the ambient quiescent corona. The magnetic nature of these coronal features is not well understood. // Aims: We study the magnetic properties of the weakly emitting extended regions, which we name coronal voids. In particular, we aim to understand whether these voids result from a reduced heat input into the corona or if they are associated with mainly unipolar and possibly open magnetic fields, similar to coronal holes. // Methods: We defined the coronal voids via an intensity threshold of 75% of the mean quiet-Sun (QS) EUV intensity observed by the high-resolution EUV channel (HRIEUV) of the Extreme Ultraviolet Imager on Solar Orbiter. The line-of-sight magnetograms of the same solar region recorded by the High Resolution Telescope of the Polarimetric and Helioseismic Imager allowed us to compare the photospheric magnetic field beneath the coronal voids with that in other parts of the QS. // Results: The coronal voids studied here range in size from a few granules to a few supergranules and on average exhibit a reduced intensity of 67% of the mean value of the entire field of view. The magnetic flux density in the photosphere below the voids is 76% (or more) lower than in the surrounding QS. Specifically, the coronal voids show much weaker or no network structures. The detected flux imbalances fall in the range of imbalances found in QS areas of the same size. // Conclusions: We conclude that coronal voids form because of locally reduced heating of the corona due to reduced magnetic flux density in the photosphere. This makes them a distinct class of (dark) structure, different from coronal holes
