    Dataset available in: https://repositorio.aemet.es/handle/20.500.11765/7914Using clustering analysis for the SLP field of the ERA Interim reanalysis between 1979 and 2016, five synoptic pressure patterns have been obtained for Drake area and Antarctic Peninsula (AP) region (45°S 75°S 20°W 120°W) and the resulting daily series has been made available to the scientific community. The five patterns have been named according their most important features as Low over the Weddell Sea (LWS), Low over the Amundsen and Bellingshausen Seas (LAB), Low over the Drake Passage (LDP), Zonal over the Drake Passage (ZDP) and Ridge over the Antarctic Peninsula (RAP). Each atmospheric pattern has been described after analyzing their development and evolution. A frequency analysis shows that the 5 atmospheric patterns present a similar annual frequency but a large seasonal variability. Their transitions from one to other pattern tends to follow a cycle in which synoptic atmospheric waves displaces eastwards a quarter-wavelength. Four of the five atmospheric patterns (except RAP) are very influenced by SAM, only LAB and LWS are influenced to some degree by ENSO. Occurrence of LAB pattern presents a positive trend showing agreement with other studies that indicates an enhancement of the Amundsen-Bellingshausen Sea Low. Finally, atmospheric circulation patterns have been related with the airmass advection and precipitation in Livingston Island showing the potential application to study the changes in the surface mass balance on the AP cryosphere.This work is supported by Ministry of Economy and Competitiveness (MINECO) trough AEMET Antarctic program and by the Spanish Investigation Agency (AEI) and the European Regional Development Fund (FEDER), grant CTM2016-79741-R for MICROAIRPOLAR Project

    This study aimed to evaluate the effectiveness of oral amoxicillin/clavulanate (AMX-CL) for the prevention of bacteremia following dental extractions. The study group (AMX-CLG) comprised 40 adults requiring dental extractions under general anesthesia who were administered a prophylactic regimen of 1875/125 mg of AMX-CL orally 1–2 h prior to the surgery. Venous blood samples were collected from each patient at baseline and at 30 s and 15 min after dental extractions. Samples were inoculated into BACTEC Plus culture bottles and processed in the BACTEC 9240. Conventional microbiological techniques were used for subcultures and further identification of the isolated bacteria. The results for the AMX-CLG were compared with those of a control group (CG; no prophylaxis) and an amoxicillin group (AMXG; 2 g of amoxicillin orally), consisting of randomly selected patients from among those participating in two clinical trials that we have previously published. The prevalence of bacteremia in the CG, AMXG, and AMX-CLG was 97%, 50%, and 15%, respectively, at 30 s after completing the extractions, and 67%, 10%, and 4% at 15 min, respectively, after the last extraction. The prevalence of bacteremia in the AMXG and the AMX-CLG at 30 s and at 15 min after completing the extractions was significantly lower than that in the CG (p < 0.001 and p < 0.001, respectively; Fisher’s exact test). The prevalence of bacteremia in the AMX-CLG at 30 s after completing the extractions was significantly lower than that in the AMXG (p < 0.001; Fisher’s exact test). Based in the results of this preliminary study, oral AMX-CL could be an excellent option for preventing bacteremia secondary to dental procedures in patients at riskS

    The fate of SARS-COV-2 in WWTPS points out the sludge line as a suitable spot for detection of COVID- 19

    SARS-CoV-2 genetic material is detectable in the faeces of a considerable part of COVID-19 cases and hence, in municipal wastewater. This fact was confirmed early during the spread of the COVID-19 pandemic and prompted several studies that proposed monitoring its incidence by wastewater. This paper studies the fate of SARS-CoV-2 genetic material in wastewater treatment plants using RT-qPCR with a two-fold goal: i) to check its presence in the water effluent and in the produced sludge and ii) based on the understanding of the virus particles fate, to identify the most suitable spots for detecting the incidence of COVID-19 and monitor its evolution. On the grounds of the affinity of enveloped virus towards biosolids, we hypothesized that the sludge line acts as a concentrator of SARS-CoV-2 genetic material. Sampling several spots in primary, secondary and sludge treatment at the Ourense (Spain) WWTP in 5 different days showed that, in effect, most of SARS-CoV-2 particles cannot be detected in the water effluent as they are retained by the sludge line. We identified the sludge thickener as a suitable spot for detecting SARS-CoV-2 particles thanks to its higher solids concentration (more virus particles) and longer residence time (less sensitive to dilution caused by precipitation). These findings could be useful to develop a suitable strategy for early warning of COVID-19 incidence based on WWTP monitoringSabela Balboa, Miguel Mauricio-Iglesias and Juan M.

    Introduction:Infections caused by carbapenem-resistant Enterobacterales (CRE) and carbapenem-resistant Pseudomonas aeruginosa, including isolates producing acquired carbapenemases, constitute a prevalent health problem worldwide. The primary objective of this study was to determine the distribution of the different carbapenemases among carbapenemase-producing Enterobacterales (CPE, specifically Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae complex, and Klebsiella aerogenes) and carbapenemase-producing P. aeruginosa (CPPA) in Spain from January 2014 to December 2018.Methods: A national, retrospective, cross-sectional multicenter study was performed. The study included the first isolate per patient and year obtained from clinical samples and obtained for diagnosis of infection in hospitalized patients. A structured questionnaire was completed by the participating centers using the REDCap platform, and results were analyzed using IBM SPSS Statistics 29.0.0.Results: A total of 2,704 carbapenemase-producing microorganisms were included, for which the type of carbapenemase was determined in 2692 cases: 2280 CPE (84.7%) and 412 CPPA (15.3%), most often using molecular methods and immunochromatographic assays. Globally, the most frequent types of carbapenemase in Enterobacterales and P. aeruginosa were OXA-48-like, alone or in combination with other enzymes (1,523 cases, 66.8%) and VIM (365 cases, 88.6%), respectively. Among Enterobacterales, carbapenemase-producing K. pneumoniae was reported in 1821 cases (79.9%), followed by E. cloacae complex in 334 cases (14.6%). In Enterobacterales, KPC is mainly present in the South and South-East regions of Spain and OXA-48-like in the rest of the country. Regarding P. aeruginosa, VIM is widely distributed all over the country. Globally, an increasing percentage of OXA-48-like enzymes was observed from 2014 to 2017. KPC enzymes were more frequent in 2017–2018 compared to 2014–2016.Discussion: Data from this study help to understand the situation and evolution of the main species of CPE and CPPA in Spain, with practical implications for control and optimal treatment of infections caused by these multi-drug resistant organisms

    Influencias italianas en la educación española e iberoamericana

    Producción CientíficaEn nuestro ámbito iberoamericano (europeo y americano), y también africano, reconocemos una presencia constante entre nosotros, más o menos influyente en su intensidad, y durante muchos siglos, de algunos productos y valores culturales, educativos y pedagógicos generados o procedentes de lo que pueda considerarse un referente próximo o equivalente a lo que denominamos hoy Italia. Utilizando la metáfora que Harold Bloom presenta en su sugerente obra El canon occidental para la literatura, tal vez podamos preguntarnos por qué tantos elementos de la educación, la pedagogía y la cultura procedentes de Italia han ido formando parte de lo que podríamos denominar de forma un tanto atrevida ese «canon pedagógico iberoamericano» que configura nuestro humus pedagógico contemporáneo en América Latina, Portugal, España, y en algún sentido también en África. Por qué se ha producido esa permeabilidad e influencia educativa tan fuerte y extensa de lo italiano sobre nuestros sistemas educativos, sobre los saberes que se difunden. Por qué han alcanzado muchos de esos elementos procedentes de la educación y cultura italianas, a veces de tradición secular, un cierto grado de universalidad entre nosotros, y se han convertido en pedagógicamente canónicos e influyentes. Conviene recordar que Italia representa uno de los ámbitos más influyentes en todo el mundo a la hora de proponer elementos transformadores de la educación, porque al fin este es un proceso de creatividad e imaginación de todos, y en ello los italianos han aprendido a producir de vez en cuando ofertas, productos y hombres capaces de situar la educación en el corazón de nuevos estilos de ser y vivir. De todo ello hablan, de forma explícita o indirecta, los trabajos que componen esta obra sobre las influencias italianas en la educación española, iberoamericana y africana.Departamento de Historia del Art
