Dos miradas sobre la mujer etrusca

This paper studies two concrete aspects of the role of women in Etruria in the VIth century BC: on the one part, her situation in society and family, and on the other, the possibilities that women had, within the previous context, of choosing their outward appearance and clothing. These questions will be analyzed using classical texts, inscriptions, and above all, Etruscan art of the Archaic Period

Cleopatra o Ariadna: retorno a un debate superado

The iconography of the Hellenistic statue called Sleeping Ariadne, known throw several Roman copies, has been interpreted in various ways from the Renaissance till today. We shall re-examine this set of problems in the context of the ideological evolution.La iconografía de la escultura helenística llamada Ariadna dormida, conocida por varias copias romanas, ha dado lugar a diversas interpretaciones desde el Renacimiento hasta hoy. Deseamos repasar esta problemática insertándola en la evolución de las mentalidades

Patient-Level, Institutional, and Temporal Variations in Use of Imaging Modalities to Confirm Pulmonary Embolism

International audienceBackground: The choice of the imaging modality for diagnosis of pulmonary embolism (PE) could be influenced by provider, patient or hospital characteristics, or over time. However, little is known about the choice of the diagnostic modalities in practice. The aim of this study was to evaluate the variations in the use of imaging modalities for patients with acute PE. Methods: Using the data from Registro Informatizado Enfermedad TromboEmbolica (RIETE), a prospective international registry of patients with venous thromboembolism (March 2001–January 2019), we explored the imaging modalities used in patients with acute PE. The imaging modalities included computed tomography pulmonary angiography, ventilation/perfusion scanning, pulmonary angiography, a combination of these tests, or PE signs and symptoms plus imaging-confirmed proximal deep vein thrombosis but no chest imaging. Results: Among 38 025 patients with confirmed PE (53.1% female, age: 67.3±17 years), computed tomography pulmonary angiography was the dominant modality of diagnosis in all RIETE enrollees (78.2% [99% CI, 77.6–78.7]); including pregnant patients (58.9% [99% CI, 47.7%–69.4%]) and patients with severe renal insufficiency (62.5% [99% CI, 59.9–65.0]). A greater proportion of patients underwent ventilation/perfusion scanning in larger hospitals compared with smaller hospitals (13.1% versus 7.3%, P <0.001). The use of computed tomography pulmonary angiography varied between 13.3% and 98.3% across the countries, and its use increased over time (46.5% in 2002 to 91.7% in 2018, P <0.001). Conclusions: In a large multinational PE registry, variations were observed in the use of imaging modalities according to patient or institutional factors and over time. However, computed tomography pulmonary angiography was the dominant modality of diagnosis, even in pregnancy and severe renal insufficiency. The safety, costs, and downstream effects of these tests on PE-related and non-PE-related outcomes warrant further investigation
