Estudio de la cimentación del Hospital de Las Cinco Llagas de Sevilla

En los años 1997-98, se realizaron los estudios previos al proyecto de Restauración (Segunda Fase) del edificio que alberga la actual sede del Parlamento de Andalucía, el Hospital de Las Cinco Llagas. Esta Segunda Fase de Rehabilitación del edificio comprende los Patios del Cardenal, de la Fuente y de las Flores. Dichos estudios previos tenían un programa de estudio y análisis exhaustivo de todos los elementos estructurales del edificio, aunque en esta comunicación nos centraremos en el análisis de la cimentación

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Modelo para determinar la solución constructiva de cimentaciones en edificación, en función de los condicionantes geotécnicos en Sevilla

La elección de la tipología de la cimentación de un edificio se realiza según un conjunto de ideas basadas en los conocimientos y experiencias previas del técnico responsable, sin obedecer a un patrón explícito organizado y desarrollado. Si bien este modelo ha funcionado correctamente, también han producido fallos derivados en la mayoría de los casos al no considerar todos los factores implicados en la decisión. En esta Tesis se ha elaborado un modelo que permite analizar los condicionantes que debe tener en la mente el técnico antes de la elección del sistema constructivo más adecuado, de una forma ordenada y organizada. En ella se desarrolla un modelo de referencia para la óptima selección del tipo de cimentación en obras de edificación en el ámbito de la ciudad de Sevilla, que con un entorno, marco físico y geomorfológico característico, características geotécnicas recurrentes y sistemas de cimentación convencionales, ha hecho posible aflorar el patrón de razonamiento. Se ha generado una metodología científicamente justificada y contrastada de aplicación práctica a partir de la realidad compleja que componen todos los factores condicionantes que intervienen en el proceso de elección. Así como unas directrices para el estudio de las distintas opciones de cimentación. Se han identificado sesenta y siete factores elementales condicionantes que intervienen específicamente en la ciudad de Sevilla, que se han clasificado en categorías según su carácter u origen conceptual. Tras el estudio particular y exhaustivo de los factores inicialmente identificados, se deduce que algunos de ellos no son relevantes y otros sin embargo adquieren un peso especial en decisión. El modelo se ha racionalizado en número a partir de una jerarquización y relativización de su participación, estableciendo interrelaciones y justificando su integración en seis grupos de factores conexos entre sí, cuya interpretación se puede realizar de forma conjunta en los denominados factores sintéticos. Por cada uno de los factores, se proponen criterios y datos concretos de aplicación para valorar las características geotécnicas, asociadas a los procesos geomorfológicos, del entorno, de la estructura y constructivos, de forma que cualquier agente que participe en un proceso de diseño o análisis de una cimentación en Sevilla disponga de una metodología para asegurar una elección adecuada

Estudio de la adherencia piedra-mortero

Stones placates present a wide of problems that result in the fall of plates. One of the causes is the lack of adherence stone-mortar. We considered a study to determine the adherence between several cement mortars (1:3, 1:5, 1:7, 1:9 and a especial mortar prepared with latex) and stones (white granite, pink granites, black granites, white marble and cream limestones). The results obtained suggest that only adequate adherence rates (higher than 3 kgf/cm2) achieved with cement mortar 1:3 and especial mortar. Besides it is observed that in the stones studied there is no relation between adherence and the absorption values.Los aplacados de piedra presentan una extensa patología que se traduce en la caída de las placas colocadas. Una de las causas es la falta de adherencia mortero-piedra. El estudio se realiza para determinar la tensión de adherencia entre diversos morteros de cemento (1:3, 1:5, 1:7, 1:9 y otro compuesto por mortero y látex) y piedras (granito blanco, granitos rosa, granitos negros, mármol blanco y calizas crema). De los resultados obtenidos se deduce que los únicos morteros que permiten valores de adherencia aceptables (superiores a 3 kp/cm2) son el mortero de cemento 1:3 y el especial. Igualmente se comprueba que, en las piedras estudiadas, no existe relación alguna entre la adherencia y la absorción de agua

Study of the church San Miguel in Morón, Sevilla: influence of the humidity alteration in the stability of monument

Gran parte de los daños que sufren las fábricas de las edificaciones históricas, tienen su origen en las humedades de capilaridad. Una de las propuestas para eliminarlas es la desviación o modificación del nivel freático. Ello trae consigo la desecación del terreno de apoyo de la cimentación, al pasar de un estado saturado a otro de humedad natural En aquellos casos en los que los suelos de apoyo de la cimentación estén constituidos por arcillas de alta plasticidad se producirían procesos de retracción, cuya consecuencia podría ser la aparición de asientos diferenciales, que afectarían de forma negativa a la estructura. Para explicar este fenómeno se describe el estudio realizado en la iglesia de San Miguel de Morón dela Frontera (Sevilla).Most of the damages that the brick walls of historical buildings show, have the origin in capillary humidity. The way to remove this capillary humidities, is frequently by the deflection of the freatic level. This method causes the dessication of the soil where lays the foundation of the building, and when the soil is constituted of clays of high plasticity, it happens processes of retraction, that causes the differential settling of the foundation, affecting negatively to the structure of the building. To explain this fact, we describe the studies realized in the foundation of the church of San Miguel in Morón, Sevilla

Patterns of oral anticoagulant use and outcomes in Asian patients with atrial fibrillation: a post-hoc analysis from the GLORIA-AF Registry

Background: Previous studies suggested potential ethnic differences in the management and outcomes of atrial fibrillation (AF). We aim to analyse oral anticoagulant (OAC) prescription, discontinuation, and risk of adverse outcomes in Asian patients with AF, using data from a global prospective cohort study. Methods: From the GLORIA-AF Registry Phase II-III (November 2011-December 2014 for Phase II, and January 2014-December 2016 for Phase III), we analysed patients according to their self-reported ethnicity (Asian vs. non-Asian), as well as according to Asian subgroups (Chinese, Japanese, Korean and other Asian). Logistic regression was used to analyse OAC prescription, while the risk of OAC discontinuation and adverse outcomes were analysed through Cox-regression model. Our primary outcome was the composite of all-cause death and major adverse cardiovascular events (MACE). The original studies were registered with ClinicalTrials.gov, NCT01468701, NCT01671007, and NCT01937377. Findings: 34,421 patients were included (70.0 ± 10.5 years, 45.1% females, 6900 (20.0%) Asian: 3829 (55.5%) Chinese, 814 (11.8%) Japanese, 1964 (28.5%) Korean and 293 (4.2%) other Asian). Most of the Asian patients were recruited in Asia (n = 6701, 97.1%), while non-Asian patients were mainly recruited in Europe (n = 15,449, 56.1%) and North America (n = 8378, 30.4%). Compared to non-Asian individuals, prescription of OAC and non-vitamin K antagonist oral anticoagulant (NOAC) was lower in Asian patients (Odds Ratio [OR] and 95% Confidence Intervals (CI): 0.23 [0.22-0.25] and 0.66 [0.61-0.71], respectively), but higher in the Japanese subgroup. Asian ethnicity was also associated with higher risk of OAC discontinuation (Hazard Ratio [HR] and [95% CI]: 1.79 [1.67-1.92]), and lower risk of the primary composite outcome (HR [95% CI]: 0.86 [0.76-0.96]). Among the exploratory secondary outcomes, Asian ethnicity was associated with higher risks of thromboembolism and intracranial haemorrhage, and lower risk of major bleeding. Interpretation: Our results showed that Asian patients with AF showed suboptimal thromboembolic risk management and a specific risk profile of adverse outcomes; these differences may also reflect differences in country-specific factors. Ensuring integrated and appropriate treatment of these patients is crucial to improve their prognosis. Funding: The GLORIA-AF Registry was funded by Boehringer Ingelheim GmbH
