Spanish children's diet: compliance with nutrient and food intake guidelines

OBJECTIVE: To compare the diet of Spanish children against the nutrient and food intake guidelines. To calculate an index of overall diet quality and check its validity against nutrient intake. DESIGN AND SETTING: Cross-sectional study in four cities in Spain, where information on food and nutrient intake was obtained from schoolchildren through a food frequency questionnaire. PARTICIPANTS: The sample included 1112 children (overall response rate of 85%) attending public and private schools and aged 6-7 y. Children were selected through random cluster sampling in schools, and stratified by sex and socioeconomic level. MAIN OUTCOME MEASURES: Mean nutrient intake, number of food servings, and the percentage of children who meet recommended nutrient and food-serving intake levels. The overall dietary quality was assessed using the Healthy Eating Index (HEI). RESULTS: Mean micronutrient intake exceeded 100% of the recommended dietary allowances, except for vitamin B6, which registered a mean intake of 77.1%. For almost all children, intake of saturated fat was above, and that of carbohydrate below, the recommended level, in contrast to the relatively high compliance with the recommendations for poly- and monounsaturated fatty acid, salt and fiber intake (69.7, 43.7, 40.7, and 30.1%, respectively). Consumption of food servings for each of the five American pyramid food groups came close to or exceeded USDA guidelines, with the exception of cereals, with 5.4 servings per day. The mean score obtained in the HEI was 64.6. Children who complied with all the food guide pyramid recommendations registered a higher dietary variety and a healthier nutritional profile. CONCLUSIONS: Children aged 6-7 y show scant compliance with the macronutrient goals for healthy eating. Micronutrient intake is adequate in general, yet there are small groups of children with risk of deficient intake of vitamins B6 and D. While Spanish children's eating habits are reasonably in line with American food guide pyramid guidelines, consumptions of cereals and fruit should be improved.This study was partly funded by grants from the Inter-national Olive Oil Board (Consejo Oleı ́cola Internacional),Comunidad de Madrid, Fundacio ́n Pedro Barrie ́de laMaza, and Fundacio ́n Eugenio Rodrı ́guez Pascua

Enhanced detection of viral RNA species using fokI-assisted digestion of DNA duplexes and DNA/RNA hybrids

The accurate detection of nucleic acids from certain biological pathogens is critical for the diagnosis of human diseases. However, amplified detection of RNA molecules from a complex sample by direct detection of RNA/DNA hybrids remains a challenge. Here, we show that type IIS endonuclease FokI is able to digest DNA duplexes and DNA/RNA hybrids when assisted by a dumbbell-like fluorescent sensing oligonucleotide. As proof of concept, we designed a battery of sensing oligonucleotides against specific regions of the SARS-CoV-2 genome and interrogated the role of FokI relaxation as a potential nicking enzyme for fluorescence signal amplification. FokI-assisted digestion of SARS-CoV-2 probes increases the detection signal of ssDNA and RNA molecules and decreases the limit of detection more than 3.5-fold as compared to conventional molecular beacon approaches. This cleavage reaction is highly specific to its target molecules, and no detection of other highly related B-coronaviruses was observed in the presence of complex RNA mixtures. In addition, the FokI-assisted reaction has a high multiplexing potential, as the combined detection of different viral RNAs, including different SARS-CoV-2 variants, was achieved in the presence of multiple combinations of fluorophores and sensing oligonucleotides. When combined with isothermal rolling circle amplification technologies, FokI-assisted digestion reduced the detection time of SARS-CoV-2 in COVID-19-positive human samples with adequate sensitivity and specificity compared to conventional reverse transcription polymerase chain reaction approaches, highlighting the potential of FokI-assisted signal amplification as a valuable sensing mechanism for the detection of human pathogens.Funding was provided by the ISCIII (COV00624 to J.R.T. andM.F.F., PI18/01527 and PI21/01067 to M.F.F.), CSIC (202020E092 to M.F.F), the European Commission NextGenerationEU, through CSIC’s Global Health Platform (PTI Salud Global) and the Spanish Ministry of Science and Innovation through the Recovery, Transformation and Resilience Plan (GL2021-03-39 and GL2021-03-040), the PCTI from the Asturias Government, co-funded by 2018−2022/FEDER (IDI/2018/146 to M.F.F.), the AECC (PROYE18061FERN to M.F.F), ISPA-Janssen (048-Intramural Nov-Tevar to J.R.T.) and the IUOPA.

Radon (222Rn) outgassing in San Juan volcanic tubes during the Cumbre Vieja eruption 2021, and preliminary values in the new volcanic tubes

Comunicación oral presentada en el 1st European Meeting on Geomicrobiology of volcanic caves. días 2-3 de marzo de 2023 celebrado en la Casa de la Ciencia-CSIC de SevillaDuring the eruption at Cumbre Vieja ridge (La Palma, Canary Islands, 2021) a radon (222Rn) detector (CORENTIUM Pro alpha particles counter) was emplaced inside the “Las Palomas” lava tube (San Juan eruption, 1949). In addition, a CO2 meter logger was emplaced to determine relationships between the 2021 eruption and radon plus CO2 inner fluxes. There is a geostructural relationship between the 1949 and 2021 eruptions, probably connected by a previous fault, shown the volcanic vents’ alignment trending NW-SE. In October 2021, the radon and CO2 loggers were moved to the upper part of the lava tube, in the San Juan volcanic vent (Llano del Banco hollow dyke). Once the eruption ended (in early 2022) both loggers were placed in one newly formed lava tube, and data will be collected in February 2023. Preliminary results show daily average radon values ranging between 2 - 9 Bq/m3, although sporadic peaks of about 270 and 650 Bq/m3 were recorded related to volcano-tectonic earthquakes and volcanic intensity. In general, basaltic eruptions of alkaline affinity show low radon values due to the low concentration in the magma body of uranium and related chemical elements (Th, Ra, etc.). Geochemical analysis of emitted lavas shows a U concentration of about 1 to 5 ppm (μg/g) and Th 9.5 ppm. Summer values of Rn increased up to 3 KBq/m3, related to the climate conditions instead of volcanic activity.This study was funded by the project CSIC 20223PAL002 “Investigación Geológica de la Erupción de 2021 en Cumbre Vieja” and partially by the project FAMRAD (PID2020-113407RB-I00): Geochemical modeling of seismic prediction from endogenous gas emission (222Rn, CO2, CH4), and earthquakes by using radioactive caves and boreholes in the Alhama de Murcia fault.N

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

The uranium mineralizations of La Carretona and Casa del Gallo in Albalâ cranite (Câceres), Spain.

The U mineralizations that are estudied in this paper are hosted in Albalagranite.They are controled by late Hercinian vertical or subvertical faults, with an aproximate orientation of N30°E. The mineral association in them comprises pichblenda, coffinite, blackoxides, piryte mar casite,melnicovite and some sphalerite in La Carretona, and black oxides,pyrite and melnicovite in Casa del Gallo. In both cases the gangue is made up of quartz, jasper and apatite.The origin of the uranium that gives rise to these mineralizations comes from the remobilizations of this element present in the host granite, basically in the form of uraninite, as a consequence of the early hydrothermal weathering of these granites, which occurred during,discontinuous proceses and supergenic weathering .Hence, we suggest that the first mineralizing process of the uranium took place during the sub-solid state of the granite, as a consequence of the leaching of U due to late hydrothermal fluids during the Permian Period, the posibility of a remobilization of U during the late alpinefracturation cannot be excluded. Finally, from the end of the tertiary to the present the latest stage of weathering and a concentration of the U have occurred, forming the hexavalent mineral

Rare earth minerals in carbonatites at the Fuerteventura Basal Complex (Canary Islands)

The Fuerteventura carbonatites appear in the Complejo Basal as veins, breccias and shear bands in the coastline between Puerto de la Pena and Cueva de Lobos, and in the Esquinzo ravine zone. These carbonatites are formed by calcite mainly and apatite, aegirine-augite, albite, orthoclase-sanidine, biotite, epidote and ore minerals occur in lower amounts, and as accessory minerals titanite, zircon, garnet, celestite, barite, brithdlite, allanite, pyrochlore and monazite. Geochemical analysis o f these carbonatites show high values] of REE between 511 and 7,372 ppm, with high relation LREE/HREE. Microprobe studies show that these elements mainly are associated with phosphates (britholite, monazite and apatite), silicates (allanite and titanite), oxides (pyrochlore), carbonates (bastnaesite) and sulphates (barite). The carbonatites have been generated in the last magmatic-hydrothermal crystallization phases of the alkaline intrusive complexes of Fuerteventur
