Estilos de gestión de los perfiles políticos en Twitter: imagen y texto en las cuentas de los partidos en la campaña del 26J

2019

En este trabajo analizamos dos aspectos de las cuentas de los partidos políti - cos en Twitter durante la campaña del 26J: la estructura semiótica de los tuits y su función comunicativa. El análisis de estas dos varia - bles permite concluir que 1) las cuentas de los partidos carecen en general de voz insti - tucional y tienen sobre todo carácter ecoico respecto a las cuentas de los líderes, espe - cialmente los candidatos; 2) existe equilibrio entre el uso de texto e imagen; 3) la función predominante es el tuit de cita; 4) las cuentas son uniformes, solo destaca la de IZQUIER - DA UNIDA por su alto índice de especta - cularización de la política. No hay, en defi - nitiva, un estilo de ges…

High Rate of Studies with Level 1 and 2 Evidence among the 100 Most Cited Articles in Lumbar Spinal Stenosis.

2021

Abstract Background To date, no study has used bibliometric analysis to review the most influential articles in lumbar spinal stenosis. The objective of this study was to identify and analyze the characteristics and the level of evidence of the 100 most cited articles on lumbar spinal stenosis Methods The Thomson Reuters Web of Science was accessed to find the 100 most cited articles on lumbar spinal stenosis. For each article, we recorded the number and density of citations, authors, country, journals and years, department, level of evidence, type of study, and if it was part of any multicenter studies. Results Until January 2017, the 100 most cited articles accumulated 11,136 citations (a…

Notas a la diacronía y la fraseología de andana y traque

2022

El estudio fraseológico del español carece todavía hoy de una obra lexicográfica en la que sus unidades se vean descritas en su historia. Aunque el DHISFRAES llena parcialmente ese vacío, no pocos trabajos han podido detallar la historia de un número importante de unidades fraseológicas. El presente estudio pretende adherirse a ellos, explorando desde los preceptos de la fraseología histórica las unidades fraseológicas que tienen como núcleo andana y traque, ambas palabras diacríticas.

Pathophysiology of traumatic brain injury.

2007

The knowledge of the pathophysiology after traumatic head injury is necessary for adequate and patient-oriented treatment. As the primary insult, which represents the direct mechanical damage, cannot be therapeutically influenced, target of the treatment is the limitation of the secondary damage (delayed non-mechanical damage). It is influenced by changes in cerebral blood flow (hypo- and hyperperfusion), impairment of cerebrovascular autoregulation, cerebral metabolic dysfunction and inadequate cerebral oxygenation. Furthermore, excitotoxic cell damage and inflammation may lead to apoptotic and necrotic cell death. Understanding the multidimensional cascade of secondary brain injury offers…

Antihyperalgesic and analgesic properties of the N-methyl-d-aspartate (NMDA) receptor antagonist neramexane in a human surrogate model of neurogenic …

2006

Abstract NMDA-receptors are a major target in the prevention and treatment of hyperalgesic pain states in neuropathic pain. However, previous studies revealed equivocal results depending on study design and efficacy parameters. We tested the analgesic (generalized reduction of generation and processing of nociceptive signalling) and anti-hyperalgesic (prevention of central sensitization) properties of the NMDA-receptor antagonist neramexane and the potassium channel opener flupirtine in the intradermal capsaicin injection model. Furthermore, we tested the effect on pain summation (wind up). Eighteen healthy subjects received either a single dose of neramexane (40 mg p.o.), flupirtine (100 m…

Good clinical practice for the use of vasopressor and inotropic drugs in critically ill patients: state-of-the-science and expert consensus

2021

Vasopressors and inotropic agents are widely used in critical care. However, strong evidence supporting their use in critically ill patients is lacking in many clinical scenarios. Thus, the Italian Society of Anesthesia and Intensive Care (SIAARTI) promoted a project aimed to provide indications for good clinical practice on the use of vasopressors and inotropes, and on the management of critically ill patients with shock. A panel of 16 experts in the field of intensive care medicine and hemodynamics has been established. Systematic review of the available literature was performed based on PICO questions. Basing on available evidence, the panel prepared a summary of evidences and then wrote…

Laryngeal Mask Airway Position and the Risk of Gastric Insufflation

1998

A potential risk of the laryngeal mask airway (LMA) is an incomplete mask seal causing gastric insufflation or oropharyngeal air leakage.The objective of the present study was to assess the incidence of LMA malpositions by fiberoptic laryngoscopy, and to determine their influence on gastric insufflation and oropharyngeal air leakage. One hundred eight patients were studied after the induction of anesthesia, before any surgical manipulations. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 40 cm H2 O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relatio…

Differential expression patterns of cytokines in complex regional pain syndrome.

2007

Complex regional pain syndromes (CRPS) are characterized by persistent and severe pain after trauma or surgery. Neuro-immune alterations are assumed to play a pathophysiological role. Here we set out to investigate whether patients with CRPS have altered systemic pro- and anti-inflammatory cytokine profiles compared to controls on mRNA and protein level. We studied blood cytokine mRNA and protein levels of the pro-inflammatory cytokines tumor necrosis factor-alpha (TNF), interleukin-2 (IL-2) and IL-8 and the anti-inflammatory cytokines IL-4, IL-10, and transforming growth factor-beta1 (TGF beta 1) in 40 prospectively recruited patients with CRPS I, two patients with CRPS II, and 34 controls…
