Impacto del confinamiento en la conducta adictiva de los universitarios riojanos
2020
Una de las implicaciones de la crisis sanitaria de la COVID-19 ha sido el confinamiento de la población. La investigación previa muestra que las situaciones de confinamiento provocan cambios en las conductas adictivas. El objetivo del presente estudio fue conocer el impacto del confinamiento en el patrón de las adicciones de los y las estudiantes universitarios con la intención de diseñar intervenciones ajustadas a las necesidades de esta población. La muestra no probabilística estuvo compuesta por 540 estudiantes de la Universidad de La Rioja, con una media de edad de 22,3 años y una proporción de mujeres del 69,3%. Los resultados indicaron un descenso significativo en el consumo de tabaco…
Spontaneous and after stimulation FSH and LH patterns in thalassemic male adolescents
1998
Background. In the last years thalassemic patients gained a good improvement in prognosis and life style. However, short stature and hypogonadism are still frequent endocrine problems in this population. Methods. In a group of eleven thalassemic males (14-18 years old), the spontaneous nocturnal endocrine patterns of LH and FSH and plasma gonadotropins in response to GnRH were studied. The profiles were analyzed using a computer program (PULSAR) to determine the secretion pattern (number and amplitude of peaks) and the area under the curve above the secretion baseline (AUC). The endocrine status was compared with liver fibrosis, iron overload and transfusional regimen. Results. A regular an…
Use of Digital Resources in Higher Education during COVID-19: A Literature Review
2022
The sudden transition from face-to-face education to remote education under the international-level restrictions imposed as a result of the COVID-19 pandemic—a transition made in the spirit of achieving and developing accessible education—involved the application of methodologically diverse resources and strategies. The objective of this article is to investigate the digital resources that have been applied in higher education institutions, paying special attention to the type and frequency of use of resources. A literature review was carried out on a total of 44 articles. The main results show that the primary resources applied in higher education institutions were videoconferencing tools,…
Tipologia, materiali e costruzione: i prospetti colonnati pubblici in Sicilia dall’età post-unitaria al ventennio fascista, tra reminiscenze archeolo…
2020
The paper analyses the debate in Sicily on the construction of the monumental colonnaded porticoes that characterise the facades of public edifices built on the island from the post- Unification period to the Fascist regime. The pronao of the Massimo Theatre in Palermo (from 1875) marks the climax of a cultural movement, which, for almost a century, was to associate the neo-Greek style with public buildings and the material of choice of Sicily’s church building tradition in a deterministic manner. Calcarenite was used to build the peristyles of the temples of the archaic and classical age, with imposing, tapered and grooved columns consisting of overlapping sections. In the Fascist period, …
Nos inventamos un mundo que no existía. Una profesión de riesgo: ser editora durante el franquismo
2021
Desde el final de la dictadura franquista, la censura editorial se ha constituido en un objeto de estudio interdisciplinar que, al inicial análisis de la constitución y entramado de la censura, incorpora el estudio de una casuística varia que redimensiona el fenómeno. Por un lado, en el contexto de los memory studies, cabe analizar qué efectos tuvo en la configuración de la memoria cultural. Por otro, tiene, además, una notable incidencia en la edición, por la autocensura y la contracensura. En concreto, este artículo explora la labor de algunas editoras que, en la Barcelona de los años sesenta y setenta, integraron una generación histórica opuesta al franquismo que lidió con la censura en …
Iatrogenic acute aortic dissection type A: insight from the German Registry for Acute Aortic Dissection Type A (GERAADA)†
2013
OBJECTIVES: Previous investigators have reported a grave prognosis for iatrogenic acute aortic dissection (iAADA), but such studies are limited by their small sample sizes. The purpose of the current study was to analyse the clinical characteristics, current management and surgical outcomes in a large number of iAADA patients identified through a multicentre registry. METHODS: Between July 2006 and June 2010, 50 centres participated in the German Registry for Acute Aortic Dissection Type A (GERAADA). Of the 2137 patients included, 100 (5%) had iAADA. We compared the clinical features and 30-day outcomes of patients with iatrogenic and spontaneous acute aortic dissection type A (sAADA). RESU…
Hereditary angiodema: a current state-of-the-art review, VII: Canadian Hungarian 2007 International Consensus Algorithm for the Diagnosis, Therapy, a…
2008
Background We published the Canadian 2003 International Consensus Algorithm for the Diagnosis, Therapy, and Management of Hereditary Angioedema (HAE; C1 inhibitor [C1-INH] deficiency) in 2004. Objective To ensure that this consensus remains current. Methods In collaboration with the Canadian Network of Rare Blood Disorder Organizations, we held the second Canadian Consensus discussion with our international colleagues in Toronto, Ontario, on February 3, 2006, and reviewed its content at the Fifth C1 Inhibitor Deficiency Workshop in Budapest on June 2, 2007. Papers were presented by international investigators, and this consensus algorithm approach resulted. Results This consensus algorithm …
Minimum cause--maximum effect: the travelogue of a bullet.
2010
This case report involves a 57-year-old male, accidentally shot in the chest with a small bore firearm. The bullet entered the left hemithorax, disrupting the left internal mammarian artery. It then penetrated the anterior wall of the right ventricle causing a pericardial tamponade. After leaving the base of the right heart it perforated the diaphragm, the liver, the spleen and the pancreas. Finally, it penetrated the abdominal aorta 3 cm proximally to the coeliac trunk and reached its final position paravertebrally. This case report illustrates that the management of even minimum gunshot wounds requires a maximum variety of surgical skills. Keywords: Thoracoabdominal injury; Shotgun wound;…
Critical role of fractalkine (CX3CL1) in cigarette smoke-induced mononuclear cell adhesion to the arterial endothelium.
2012
Background Cigarette smoking is an important risk factor for the development of cardiovascular disease, yet the pathways through which this may operate are poorly understood. Therefore, the mechanism underlying cigarette smoke (CS)-induced arterial endothelial dysfunction and the potential link with fractalkine/CX3CL1 upregulation were investigated. Methods and results Stimulation of human arterial umbilical endothelial cells (HUAECs) with pathophysiological concentrations of CS extract (1% CSE) increased CX3CL1 expression. Neutralisation of CX3CL1 activity under dynamic flow conditions significantly inhibited CSE-induced mononuclear cell adhesion to HUAECs (67%). The use of small interferi…
PRAGMÁTICA DE LA PUNTUACIÓN Y NUEVAS TECNOLOGÍAS
2014
La puntuación ha evolucionado a lo largo de la historia, no solo en cuanto al número de signos, sino también con respecto a su función de guía en la (re)presentación y el procesamiento del texto. El objetivo del presente artículo es discutir la pragmática de la puntuación en los principales modos de comunicación mediada por ordenador. Mi propuesta consiste en considerar que las nuevas formas escritas de interacción mediada por ordenador situadas en el polo de la inmediatez comunicativa han dado lugar a un particular sistema de puntuación metarrepresentativa que compite con los códigos de puntuación tanto retórico como gramatical. Punctuation has evolved through history, not only in the numb…
