Composición Arquitectónica 5 y 6

La presente Memoria culmina el trabajo colaborativo del área de conocimiento de Composición Arquitectónica por lo que respecta a las materias de Grado en (Fundamentos en) Arquitectura, al haber definido sus contenidos, sus métodos de aprendizaje y sus sistemas de evaluación para el conjunto de la titulación. Ahora se concretan las dos últimas asignaturas de 5º curso: CA5 y CA6. Por un lado está CA5, cuyo eje fundamental es la definición de criterios para el ejercicio de la crítica de arquitectura, una vez que se ha construido una base de información histórica y teórica en los estudiantes a lo largo de cuatro cursos. Una crítica entendida tanto como sistema de contextualización sobre las obras ejecutadas (del presente o del pasado) y, a la vez, como marco de referencia para someter a evaluación las soluciones que se proponen desde proyecto (desde el presente hacia el futuro). Así pues, crítica entendida como herramienta de análisis tanto como de prospección. Por otro lado está CA6, en la que el eje fundamental es la intervención sobre el patrimonio arquitectónico, sea o no monumental, entendido como una realidad ineludible pues gran parte del trabajo de los arquitectos transita sobre preexistencias en sus muy diversos grados

Composición Arquitectónica: Teoría, historia, crítica y patrimonio arquitectónicos

Tras la implantación del Grado en Arquitectura (2010) y su inminente sustitución por el Grado en Fundamentos de la Arquitectura (2014), organizados ambos en cinco cursos donde se suceden seis asignaturas de Composición Arquitectónica –una introducción (CA1), dos historias de la arquitectura (CA2 y CA3), teoría (CA4), crítica (CA5) y patrimonio arquitectónicos (CA6)–, esta memoria plantea una reflexión acerca del contenido y enfoque de estas materias en el diseño de programas específicos de estudios avanzados de Composición Arquitectónica que vinculen el final de una titulación de Grado de clara vocación generalista –según establece el EEES– con el inicio de una nueva etapa de especialización propia del Postgrado. Con el fin de ayudar al alumnado a orientarse en este momento de transición clave en su trayectoria académica, se ha considerado prioritario ofrecerle una serie de temas marco y herramientas conceptuales que, desde su encaje en un conjunto de líneas de investigación que respondan a los intereses compartidos por profesores/as y estudiantes, más allá de propiciar el éxito de su Trabajo Final de Grado (TFG), aporten una visión estratégica con la que contribuir a explicitar la pertinencia y condiciones de partida de su futuro enunciado de Trabajo Final de Máster (TFM)

Composición arquitectónica: Historia, Teoría, Crítica y Patrimonio de la Arquitectura

La presente Memoria realiza balance de todas las asignaturas del área de conocimiento Composición Arquitectónica (acCA), una vez que se han implantado los cinco cursos del plan de Grado en Arquitectura (2010) y que este se está sustituyendo por el nuevo Grado en Fundamentos en Arquitectura (2014). Las asignaturas en ambos planes son prácticamente las mismas tanto en contenidos como en posición en los distintos cursos. Esta tarea se efectúa como chequeo de los objetivos trazados hace cinco años cuando se diseñó una nueva estructura docente y un nuevo método de aprendizaje (teórico y práctico) con el fin de adaptar la titulación de Arquitectura al nuevo EEES. De este modo, se repasan, para todas las asignaturas, los contenidos previstos en los descriptores de las Memorias de Grado, así como el modo de impartirlos, el sistema de prácticas, el proceso de evaluación y los resultados obtenidos. Se aprovecha estos años de experiencia para señalar las variaciones introducidas en las materias para ajustarlas a la realidad del tiempo disponible, del número de alumnos, de los avances tecnológicos y del presente social y cultural. Esta Memoria da cuenta de la satisfacción del profesorado y del alumnado, pero también señala sus limitaciones

Pulmonary vascular remodeling and prognosis in patients evaluated for heart transplantation: insights from the OCTOPUS-CHF study

[Abstract] Objective: In patients with advanced heart failure, the intravascular optical coherence tomography (OCT) of subsegmental pulmonary artery measurements is correlated with right heart catheterization parameters. Our aim was to study the prognostic value of pulmonary OCT, right heart catheterization data, and the echocardiographic estimation of pulmonary pressure in patients studied for elective heart transplants. Methods: This research is an observational, prospective, multicenter study involving 90 adults with a one-year follow-up. Results: A total of 10 patients (11.1%) died due to worsening heart failure before heart transplantation, 50 underwent a heart transplant (55.6%), and 9 died in the first year after the transplant. The patients with and without events (mortality or heart failure-induced hospitalization) had similar data regarding echocardiography, right heart catheterization, and pulmonary OCT (with a median estimated pulmonary artery systolic pressure of 42.0 mmHg, interquartile range (IQR) of 30.3-50.0 vs. 47.0 mmHg, IQR 34.6-59.5 and p = 0.79, median pulmonary vascular resistance of 2.2 Wood units, IQR 1.3-3.7 vs. 2.0 Wood units, IQR 1.4-3.2 and p = 0.99, and a median pulmonary artery wall thickness of 0.2 ± 0.5 mm vs. 0.2 ± 0.6 mm and p = 0.87). Conclusion: Pulmonary vascular remodeling (evaluated with echocardiography, right heart catheterization, and pulmonary OCT) was not associated with prognosis in a selected sample of adults evaluated for elective heart transplants. Pulmonary OCT is safe and feasible for the evaluation of these patients.Instituto de Salud Carlos III; PI18/00254European Regional Development Fund; CB16/11/0050

Impact of operatoŕs experience on peri-procedural outcomes with Watchman FLX: Insights from the FLX-SPA registry

Background: The Watchman FLX is a device upgrade of the Watchman 2.5 that incorporates several design enhancements intended to simplify left atrial appendage occlusion (LAAO) and improve procedural outcomes. This study compares peri-procedural results of LAAO with Watchman FLX (Boston Scientific, Marlborough, Massachusetts) in centers with varying degrees of experience with the Watchman 2.5 and Watchman FLX. Methods: Prospective, multicenter, 'real-world' registry including consecutive patients undergoing LAAO with the Watchman FLX at 26 Spanish sites (FLX-SPA registry). Implanting centers were classified according to the center's prior experience with the Watchman 2.5. A further division of centers according to whether or not they had performed ≤ 10 or > 10Watchman FLX implants was prespecified at the beginning of the study. Procedural outcomes of institutions stratified according to their experience with the Watchman 2.5 and FLX devices were compared. Results: 359 patients [mean age 75.5 (SD8.1), CHA2DS2-VASc 4.4 (SD1.4), HAS-BLED 3.8(SD0.9)] were included. Global success rate was 98.6%, successful LAAO with the first selected device size was achieved in 95.5% patients and the device was implanted at first attempt in 78.6% cases. There were only 9(2.5%) major peri-procedural complications. No differences in efficacy or safety results according to the centeŕs previous experience with Watchman 2.5 and procedural volume with Watchman FLX existed. Conclusions: The Watchman FLX attains high procedural success rates with complete LAA sealing in unselected, real-world patients, along with a low incidence of peri-procedural complications, regardless of operatoŕs experience with its previous device iteration or the number of Watchman FLX devices implanted

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism

Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio

All-cause mortality in the cohorts of the Spanish AIDS Research Network (RIS) compared with the general population: 1997Ł2010

Abstract Background: Combination antiretroviral therapy (cART) has produced significant changes in mortality of HIVinfected persons. Our objective was to estimate mortality rates, standardized mortality ratios and excess mortality rates of cohorts of the AIDS Research Network (RIS) (CoRIS-MD and CoRIS) compared to the general population. Methods: We analysed data of CoRIS-MD and CoRIS cohorts from 1997 to 2010. We calculated: (i) all-cause mortality rates, (ii) standardized mortality ratio (SMR) and (iii) excess mortality rates for both cohort for 100 personyears (py) of follow-up, comparing all-cause mortality with that of the general population of similar age and gender. Results: Between 1997 and 2010, 8,214 HIV positive subjects were included, 2,453 (29.9%) in CoRIS-MD and 5,761 (70.1%) in CoRIS and 294 deaths were registered. All-cause mortality rate was 1.02 (95% CI 0.91-1.15) per 100 py, SMR was 6.8 (95% CI 5.9-7.9) and excess mortality rate was 0.8 (95% CI 0.7-0.9) per 100 py. Mortality was higher in patients with AIDS, hepatitis C virus (HCV) co-infection, and those from CoRIS-MD cohort (1997. Conclusion: Mortality among HIV-positive persons remains higher than that of the general population of similar age and sex, with significant differences depending on the history of AIDS or HCV coinfection
