Human remains, funerary contexts and formal diversity: the chalcolithic sites of El Hornazo and The Burial Mound il.c1 from Cótar (Burgos)

El trabajo centra su atención en los restos humanos documentados en los yacimientos calcolíticos de El Hornazo y Túmulo IL.C1 de Cótar (Burgos). Estas evidencias no son muy habituales en el registro arqueológico de la zona oriental de la Meseta Norte, por lo que se ha realizado un estudio antropológico con el fin de obtener la mayor información posible de los mismos. No obstante, los datos obtenidos no se pueden desligar de su contexto por lo que también se presenta la información arqueológica relacionada con ellos. Los casos de estudio difieren en cuanto a patrones funerarios y cronología. Esta discrepancia necesita ser explicada. El estudio pretende no sólo presentar y discutir los aspectos formales desde un punto de vista antropológico sino plantear inferencias e hipótesis en relación al marco social donde se generaran las evidencias arqueológicas. En este sentido, se propone como hipótesis que debieron ser generadas por comunidades cuya organización se llevase a cabo bajo esquemas sociales segmentarios.The work focuses on human remains documented in the Chalcolithic sites of El Hornazo and Túmulo IL.C1 from Cótar. These remains are not very common in the archaeological record from eastern of North Plateau. So it has made an anthropological study in order to get as much information as possible from them. However, the data obtained cannot be separated from its context so that also presents archaeological information related with them. The cases of study differ as to the funerary patterns and chronology. This discrepancy needs to be explained. Therefore, the study aims not only to present and discuss the formal aspects from an anthropological point of view but to raise inferences and hypotheses regarding the social context where the archaeological evidence was generated. In this regard, it is proposed as a hypothesis that they should be created by communities who were organized under segmentary social schemes

Clinical validation of risk scoring systems to predict risk of delayed bleeding after EMR of large colorectal lesions

[Background and Aims]: The Endoscopic Resection Group of the Spanish Society of Endoscopy (GSEED-RE) model and the Australian Colonic Endoscopic Resection (ACER) model were proposed to predict delayed bleeding (DB) after EMR of large superficial colorectal lesions, but neither has been validated. We validated and updated these models.[Methods]: A multicenter cohort study was performed in patients with nonpedunculated lesions ≥20 mm removed by EMR. We assessed the discrimination and calibration of the GSEED-RE and ACER models. Difficulty performing EMR was subjectively categorized as low, medium, or high. We created a new model, including factors associated with DB in 3 cohort studies.[Results]: DB occurred in 45 of 1034 EMRs (4.5%); it was associated with proximal location (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.31-6.16), antiplatelet agents (OR, 2.51; 95% CI, .99-6.34) or anticoagulants (OR, 4.54; 95% CI, 2.14-9.63), difficulty of EMR (OR, 3.23; 95% CI, 1.41-7.40), and comorbidity (OR, 2.11; 95% CI, .99-4.47). The GSEED-RE and ACER models did not accurately predict DB. Re-estimation and recalibration yielded acceptable results (GSEED-RE area under the curve [AUC], .64 [95% CI, .54-.74]; ACER AUC, .65 [95% CI, .57-.73]). We used lesion size, proximal location, comorbidity, and antiplatelet or anticoagulant therapy to generate a new model, the GSEED-RE2, which achieved higher AUC values (.69-.73; 95% CI, .59-.80) and exhibited lower susceptibility to changes among datasets.[Conclusions]: The updated GSEED-RE and ACER models achieved acceptable prediction levels of DB. The GSEED-RE2 model may achieve better prediction results and could be used to guide the management of patients after validation by other external groups.

Duodenal diverticular bleeding: an endoscopic challenge

Duodenal diverticula are an uncommon cause of upper gastrointestinal bleeding. Until recently, it was primarily managed with surgery, but advances in the field of endoscopy have made management increasingly less invasive. We report a case of duodenal diverticular bleeding that was endoscopically managed, and review the literature about the various endoscopic therapies thus far described

Compromiso de los adolescentes de Canarias con un estilo de vida físicamente activo y saludable

The present study about adolescent from the Canary Islands, evidence that a minority of adolescents follow the guidelines or recommendations for physical activity, showing low level of physical activity of moderate intensity and vigorous, levels which are shown away from the established recommendations for this group of age, and insufficient to attain the positive effects arising from the practice of physical activity, and these low levels are more accentuated in girls than in boys. These evidences, justify, the need to change this trend and promote substantial changes in practice habits of physical activity of children and adolescents. To ensure this change, are shown as very adequate, the implementation of physical education programs out of the school schedule, along with the necessary increase in teaching hours which now is assigned to physical education in the current curriculum of Basic Education.en el presente estudio de la población adolescente de la Comunidad Autónoma de Canarias se evidencia que son minoría los adolescentes que cumplen las pautas o recomendaciones de actividad física, mostrando bajos niveles de práctica de actividad física de intensidad moderada y vigorosa, niveles que se muestran alejados de las recomendaciones establecidas para este grupo de edad e insuficientes para alcanzar los efectos positivos que se derivan de la práctica de actividad física, siendo estos bajos niveles más acentuados en las chicas que en los chicos. Estas evidencias justifican la necesidad de cambiar esta tendencia y promover cambios sustanciales en los hábitos de práctica de actividad física de nuestros niños y adolescentes. Para procurar este cambio, se muestran como muy adecuado, la puesta en práctica de programas de intervención extracurriculares, junto con el necesario incremento del horario lectivo que en la actualidad se destina a la materia de educación física en el vigente currículo escolar de la Enseñanza Básica
