UN CONJUNTO CERÁMICO EXCEPCIONAL: LA OCULTACIÓN DE CUBAS DE LA SAGRA (MADRID). ASPECTOS ICONOGRÁFICOS Y NUEVOS ESTILOS DECORATIVOS EN LA TERRA SIGILLATA HISPÁNICA TARDÍA

El estudio del ajuar cerámico de la ocultación tardorromana de Cubas de la Sagra (Madrid), formado por cuatro cuencos y cuatro grandes fuentes de terra sigillata hispánica tardía (TSHT), todos ellos decorados y completos, aporta sorprendentes novedades, entre otras en el campo de la iconografía, que ponen en tela de juicio algunos de los principios en que se fundamentaba la percepción que teníamos de esta cerámica. La constatación de nuevos estilos decorativos, en especial en las formas decoradas a molde, abre nuevas vías de investigación, al tiempo que ofrece una visión insospechada de este universo cerámico, en la que se mezclan la tradición y las modas imperantes de la época

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Multianalytical characterization of Late Roman glasses including nanosecond and femtosecond laser induced breakdown spectroscopy

In the present study, a historical set of Late Roman glasses from a recently unearthed graveyard located in the small city of Cubas de la Sagra, within the Madrid region (Spain) was compositionally analysed using different techniques such as ultraviolet-visible (UV-Vis) and laser induced fluorescence (LIF) spectroscopy, X-ray fluorescence (XRF) and laser induced breakdown spectroscopy (LIBS). LIBS results, recorded upon nanosecond (ns) and femtosecond (fs) laser irradiation, served for identification of major glass components (to classify them into main historical glass groups) and of minor components (e.g. chromophores, decolouring agents and degradation products). Quantitative information regarding these components was obtained on the basis of calibration curves obtained using glass certified standards and local standards. We have demonstrated that LIBS serves for the non-invasive/micro-destructive, quantitative chemical characterization of most of the analysed historical glasses. Furthermore, this work establishes a comparison between LIBS analysis of glasses in the ns and fs regimes on one hand, and on the other hand with the results obtained using XRF. The procedures and protocols here proposed can be applied for in situ study of historical glass collections, regardless of their size, provenance and chronology.This work was funded by MINECO (Project CTQ2013-43086-P, HAR2012-30769 and FIS2013- 44174-P) and Programa Geomateriales 2-CM (CAM, S2013/MIT-2914) and counted with the support from Techno-Heritage (Spanish Network of Science and Technology for Heritage Conservation).Peer reviewe

Los yacimientos de Tinto Juan de la Cruz, Pinto, Madrid (ss. I al VI d. C.)

The archaeological sites of Tinto Juan de la Cruz lie to the North of the present municipal area of Pinto, on the South bank of the Culebro stream. Settlements in this area can be traced back to the prehistorical age. Site 10' is a small Hihg-Empire farming settlement influenced by the indigenous building techniques and patterns, yet closely related to the urban centres of the time, as both the quality and quantity of the pottery found proves. Site 10 is a Late-Roman villa dedicated to the exploitation of the surrounding land, whose buildings are arranged according to a functional order -an area is dedicated to the owners' durelling and another to the economic activities carried out in it-. The ruin of the villa coincided with a period of generalized destruction at the beginning of 5th century. The end of the human occupation took place in the final years of 6th century, after the abandonment of the Visigothic necropolis.Los yacimientos arqueológicos de Tinto Juan de la Cruz se encuentran enclavados en el Norte del actual término municipal de Pinto, en la margen Sur del arroyo Culebro, eje de poblamiento desde época prehistórica. El yacimiento 10' parece tratarse de un pequeño asentamiento agropecuario altoimperial deudor de las técnicas y patrones constructivos indígenas, si bien muestra una importante relación con los núcleos urbanos del momento, como ponen de manifiesto tanto la calidad como la cantidad de los hallazgos cerámicos. El yacimiento 10 es una villa tardorromana dedicada a la explotación de las tierras de circundantes, cuyas edificaciones están conformadas de una manera eminentemente funcional - una zona dedicada a vivienda del señor y otra dedicada a las actividades económicas desarrolladas en su seno-. La ruina de la villa coincide con las destrucciones generalizadas de comienzos del siglo V. El final de la ocupación humana tiene lugar en los últimos años de la sexta centuria, tras el abandono de la necrópolis visigoda

ICU-Acquired Pneumonia Is Associated with Poor HealthPost-COVID-19 Syndrome

Background. Some patients previously presenting with COVID-19 have been reported to develop persistent COVID-19 symptoms. While this information has been adequately recognised and extensively published with respect to non-critically ill patients, less is known about the incidence and factors associated with the characteristics of persistent COVID-19. On the other hand, these patients very often have intensive care unit-acquired pneumonia (ICUAP). A second infectious hit after COVID increases the length of ICU stay and mechanical ventilation and could have an influence on poor health post-COVID 19 syndrome in ICU-discharged patients. Methods: This prospective, multicentre, and observational study was carrid out across 40 selected ICUs in Spain. Consecutive patients with COVID-19 requiring ICU admission were recruited and evaluated three months after hospital discharge. Results: A total of 1255 ICU patients were scheduled to be followed up at 3 months; however, the final cohort comprised 991 (78.9%) patients. A total of 315 patients developed ICUAP (97% of them had ventilated ICUAP). Patients requiring invasive mechanical ventilation had more persistent post-COVID-19 symptoms than those who did not require mechanical ventilation. Female sex, duration of ICU stay, development of ICUAP, and ARDS were independent factors for persistent poor health post-COVID-19. Conclusions: Persistent post-COVID-19 symptoms occurred in more than two-thirds of patients. Female sex, duration of ICU stay, development of ICUAP, and ARDS all comprised independent factors for persistent poor health post-COVID-19. Prevention of ICUAP could have beneficial effects in poor health post-COVID-1
