¿What is being written about Education and Pedagogy in Colombia?

Páginas 249-274El presente artículo presenta una revisión de las revistas Pedagogía y Saberes (UPN) y Praxis & Saber (UPTC) a partir de un análisis de conceptos. La pregunta por aquello que se ha producido en el campo de la educación y la pedagogía en Colombia durante las últimas décadas fue problematizada en tres momentos. En el primero, se retomaron las maneras en que se ha debatido el estatuto epistemológico de la pedagogía y la opción de usar la noción de campo como posibilidad de zanjar tensiones devenidas de la década de los ochenta. En especial, se amplía el concepto de campo conceptual de la pedagogía y se describen brevemente aspectos metodológicos del estudio. En segundo lugar, se presentan los conceptos identificados como articuladores del debate pedagógico: educación, pedagogía, formación, maestro (docente/pedagogo), escuela, disciplina, didáctica, saberes o filosofía, según sea el caso en la revista analizada; haciendo referencia a las tensiones que los caracterizan y a algunos desarrollos. Por último, se destacan tres asuntos: la adjetivación de los conceptos, las demandas de conceptualización y la necesidad de distinciones entre conceptos.This article presents a review of the journals Pedagogía y Saberes (UPN) and Praxis & Saber (UPTC) on the basis of an analysis of concepts. The question regarding what has been done in the area of education and pedagogy in Colombia during the last decades is addressed at three different stages. Firstly, a reflection is made on the ways in which the epistemological status of pedagogy has been discussed and on the possibility of using the term field as a method for easing tensions created in the eighties. In particular, the conceptual field of pedagogy concept is widened and the methodological aspects of the study are briefly described. Secondly, some key concepts articulating the debate such as: education, pedagogy, training, educator (teacher/educationist), school, discipline, didactics, knowledge, or philosophy are presented in accordance with each journal by making reference to the tensions that characterize them and some strides. Lastly, three points are highlighted: the adjectivization of the concepts, the demands for conceptualization and the need to make a clear distinction between the concepts.Bibliografía: páginas 269-274

Long-term determinants of the seroprevalence of the bluetongue virus in deer species in southern Spain

Bluetongue is a vector-borne disease affecting domestic and wild ruminants, with a major socioeconomic impact. Endemic circulation of the bluetongue virus serotype 4 (BTV-4) and BTV-1 have occurred in Spain since 2004 and 2007, respectively. However, epidemiological studies have seldom been approached from a long-term perspective in wild ruminants. A total of 881 deer (red deer and fallow deer) were necropsied from 2005 to 2018 as part of the DNP health-monitoring program. Serum samples were tested for antibodies against BTV with the aims of assessing the temporal trend and to evaluate the modulating factors: individual, populational, environmental, and stochastic. Red deer displayed statistically significant higher seroprevalences of BTV (SBT; 78.6 ± 3.8%) than fallow deer (53.1 ± 4.7%). The detection of BTV-1 and BTV-4 by the serum neutralization test in calves suggested the circulation of both serotypes over the study period. For red deer, wet years together with high densities could provide suitable conditions for vector borne BTV transmission. Moreover, proximity to high suitability habitat for Culicoides, permanent pasturelands, was associated with higher SBT. The differences in the ecology and behaviour of deer species influencing the exposure to the vectors could determine the differences found in the SBT patterns. This study evidences the role that deer species may play in the maintenance of BTV, however, elucidating the epidemiological role of host in different contexts as well as the consequences of climate change on the competent vector populations and its potential effect on the dynamics of BTV infection in hosts communities deserve further research.This research was funded by the Ministerio de Economía y Competitividad (MINECO; AEI/FEDER, UE; AGL2016-76358-R).

Long-term determinants of the seroprevalence of the bluetongue virus in deer species in southern Spain

Resumen del póster presentado a la Joint Virtual Conference of the WDA and EWDA, celebrada del 31 de agosto al 2 de septiembre de 2021.Bluetongue is a vector-borne disease affecting domestic and wild ruminants, with a major socioeconomic impact. Endemic circulation of the bluetongue virus serotype 4 (BTV-4) and BTV-1 have occurred in Spain since 2004 and 2007, respectively. However, epidemiological studies have seldom been approached from a long-term perspective in wild ruminants. 881 deer were necropsied as part of the DNP health-monitoring program. Serum samples were tested for antibodies against BTV. We assessed the main drivers of BTV maintenance in the wild ruminant hosts of Doñana National Park using generalised linear mixed models. Red deer displayed statistically significant higher seroprevalences of BTV (SBT; 78.6%) than fallow deer (53.1%). The detection of BTV-1 and BTV-4 by the serum neutralization test in calves suggested the circulation of both serotypes for the study period. For red deer, wet years together with high densities could associate to most suitable conditions for vector borne BTV transmission. Moreover, proximity to permanent pasturelands was associated with higher SBT, which may be mediated by the higher suitability of this habitat to Culicoides. The differences in the ecology and behaviour of deer species influencing the exposure to the vectors could determine the differences found in the SBT patterns. This study evidences the role that deer species may play in the maintenance of BTV in host communities. However, elucidating the epidemiological role deserves further research.Peer reviewe

Effect of Cilastatin on Cisplatin-Induced Nephrotoxicity in Patients Undergoing Hyperthermic Intraperitoneal Chemotherapy

Cisplatin is one of the most widely used chemotherapeutic agents in oncology, although its nephrotoxicity limits application and dosage. We present the results of a clinical study on prophylaxis of cisplatin-induced nephrotoxicity in patients with peritoneal carcinomatosis undergoing cytoreduction and hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC-cisplatin). Prophylaxis was with imipenem/cilastatin. Cilastatin is a selective inhibitor of renal dehydropeptidase I in the proximal renal tubule cells that can reduce the nephrotoxicity of cisplatin. Unfortunately, cilastatin is not currently marketed alone, and can only be administered in combination with imipenem. The study has a retrospective part that serves as a control (n = 99 patients receiving standard surgical prophylaxis) and a prospective part with imipenem/cilastatin prophylaxis corresponding to the study group (n = 85 patients). In both groups, we collected specific data on preoperative risk factors of renal damage, fluid management, hemodynamic control, and urine volume during surgery (including the hyperthermic chemotherapy perfusion), as well as data on hemodynamic and renal function during the first seven days after surgery. The main finding of the study is that cilastatin may exert a nephroprotective effect in patients with peritoneal carcinomatosis undergoing cytoreduction and hyperthermic intraperitoneal cisplatin perfusion. Creatinine values remained lower than in the control group (ANOVA test, p = 0.037). This translates into easier management of these patients in the postoperative period, with significantly shorter intensive care unit (ICU) and hospital stay

Underwater Quaternary record of the Cartagena Bay (Murcia, Spain)

Se perforó un sondeo de 30 m en la Bahía de Cartagena. El doble objetivo del mismo fue obtener datos sobre el antiguo frente marítimo de la ciudad romana y establecer la cronoestratigrafía y evolución paleoambiental. El sondeo (E3) se muestreó con alta resolución. Los sedimentos de la parte inferior (30-11,3 m) con predominio de colores marrones que indican condiciones oxidantes, la fauna de aguas salobres (Cerastoderma glaucum/Cyprideis torosa) y la sedimentación dominada por fangos y arenas, permiten interpretar el medio sedimentario estudiado como una llanura fangosa costera ligada a un abanico aluvial. Las edades AAR obtenidas revelan que todo el MIS5 está incluido en el registro. La parte superior (11,3-3,0 m), correspondiente al MIS 1, consiste en fangos orgánicos negros con arena y grava. Aparece una amplia diversidad de moluscos marinos en estadios juveniles de desarrollo. Todo esto representa el “cul de sac” de una bahía protegida donde se acumulaban restos vegetales, periódicamente afectada por llegadas de detríticos aluviales. Existe una somerización a techo del depósitoA new borehole was drilled at the end of the Cartagena Bay. The twofold aim of this operation was to obtain insights into the ancient Roman city seafront, and to establish its cronostratigraphy and paleoenvironmental evolution. A continuous 30 m long core (E3) was drilled and sampled with high resolution. The sediments of the lower part (30-11.3 m) with predominant brown colour indicating oxydizing conditions, the brackish-water fauna (Cerastoderma glaucum/Cyprideis torosa) and mud/sand dominance, allow to interpret the sedimentary environment as formed in a coastal mud flat linked to an alluvial fan. Consistent AAR dating ages reveal that the whole MIS5 record is included. The upper part of the record (11.3-3.0 m), which belongs to MIS 1, is made of black muddy sand and gravel. It appears a high diversity of marine mollusk species mostly in juvenile stage of development. This represents a complex environment: a “cul-d-sac” at the protected end of the bay where plant debris accumulated, being intruded by alluvial inputs. A growing continental influence likely occurred at the to

Publisher Copyright: © The Author(s) 2020. Published by Oxford University Press on behalf of ERA-EDTA.Background. The European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry collects data on kidney replacement therapy (KRT) via national and regional renal registries in Europe and countries bordering the Mediterranean Sea. This article summarizes the 2018 ERA-EDTA Registry Annual Report, and describes the epidemiology of KRT for kidney failure in 34 countries. Methods. Individual patient data on patients undergoing KRT in 2018 were provided by 34 national or regional renal registries and aggregated data by 17 registries. The incidence and prevalence of KRT, the kidney transplantation activity and the survival probabilities of these patients were calculated. Results. In 2018, the ERA-EDTA Registry covered a general population of 636 million people. Overall, the incidence of KRT for kidney failure was 129 per million population (p.m.p.), 62% of patients were men, 51% were 65 years of age and 20% had diabetes mellitus as cause of kidney failure. Treatment modality at the onset of KRT was haemodialysis (HD) for 84%, peritoneal dialysis (PD) for 11% and pre-emptive kidney transplantation for 5% of patients. On 31 December 2018, the prevalence of KRT was 897 p.m.p., with 57% of patients on HD, 5% on PD and 38% living with a kidney transplant. The transplant rate in 2018 was 35 p.m.p.: 68% received a kidney from a deceased donor, 30% from a living donor and for 2% the donor source was unknown. For patients commencing dialysis during 2009-13, the unadjusted 5-year survival probability was 42.6%. For patients receiving a kidney transplant within this period, the unadjusted 5-year survival probability was 86.6% for recipients of deceased donor grafts and 93.9% for recipients of living donor grafts.Peer reviewe

Ceramic production in las Médulas (León). A diachronic comparison by means of archaemetrical methods

[ES] El estudio arqueométrico de los patrones de producción cerámica es una herramienta eficaz para determinar el alcance de los cambios socioeconómicos y culturales de las comunidades indígenas de la Zona Arqueológica de Las Médulas (León) como consecuencia del contacto con el mundo romano. En este trabajo se presentan los resultados de la caracterización quimicofísica de un conjunto de materiales cerámicos del asentamiento metalúrgico de Orellán (s. I-II d.C.). Los datos de composición química de estos materiales se han comparado con los obtenidos en un trabajo anterior en distintos tipos cerámicos del asentamiento castreño de El Castrelín de San Juan de Paluezas (s. III-I a.C.). Los resultados de la comparación diacrónica indicaron que algunas de las cerámicas de El Castrelín podrían haberse fabricado con las mismas materias primas que las utilizadas para elaborar una buena parte de la cerámica de Orellán, lo cual sugiere una pervivencia de los patrones de producción de cerámica indígena en las comunidades ligadas a la explotación de las minas de oro de Las Médulas.[EN] The archaeometric study of pottery production patterns is an effective tool to determine the range of socioeconomic and cultural changes within indigenous communities from the archaeological zone of Las Médulas (León, Spain) as a consequence of their contact with the Roman world. This paper reports the results derived from the chemical-physical characterization of a set of ceramic materials from the metallurgical site of Orellán (1st and 2nd centuries AD). Chemical compositional data from these materials have been compared with those obtained in a previous work on ceramic types from the settlement site of El Castrelín de San Juan de Paluezas (3rd to 1st centuries BC). The diachronic comparison results indicated that some pottery from El Castrelín could have been produced with the same raw materials than those used to elaborate most part of the pottery from Orellán. This fact suggests the endurance of indigenous pottery production patterns in the communities linked to the exploitation of the gold mines of Las Médulas.Peer reviewe
