SVB en el adulto: parada cardiorespiratoria
2010
Procedimiento a seguir ante una parada cardiorespiratoria en el adulto. El sujeto esta inconsciente, no respira y no presenta pulso. Compresiones toracicas y ventilaciones (30:2). Revalorización periódica cada dos minutos, hasta que acude el equipo de soporte vital avanzado.
Sobre el procedimiento de elaboración de los reglamentos, sus vicios y su control judicial
2021
El presente trabajo analiza algunas de las cuestiones más problemáticas y relevantes, tanto desde un punto de vista teórico como práctico, que en la actualidad plantea la regulación del procedimiento de elaboración de las normas reglamentarias: (i) la de los fines que debería perseguir esta regulación; (ii) la inadecuación de este procedimiento para elaborar ciertas disposiciones administrativas atípicas; (iii) la inadecuación de las estructuras organizativas actualmente encargadas de llevar a cabo las actividades en las que consiste dicho procedimiento; (iv) la evaluación ex post de los reglamentos; y (v) las consecuencias jurídicas derivadas de sus vicios de procedimiento y su control jud…
Protein Biomarkers of Bovine Defective Meats at a Glance: Gel-Free Hybrid Quadrupole-Orbitrap Analysis for Rapid Screening
2021
An understanding of biological mechanisms that could be involved in the stress response of animal cattle prior to slaughter is critical to create effective strategies aiming at the production of high-quality meat. The sarcoplasmic proteome of directly extracted samples from normal and high ultimate pH (pHu) meat groups was studied through a straightforward gel-free strategy supported by liquid chromatography hybrid quadrupole-Orbitrap high-resolution mass spectrometry (LC-HRMS) analysis. A stepped proteomic pipeline combining rapid biomarker hunting supported by qualitative protein Mascot scores followed by targeted label-free peptide quantification revealed 26 descriptors that characterize…
Valoración médico-legal de las lesiones producidas por las prótesis mamarias Poly Implant Prothèse (PIP)
2018
La valoración médico-legal de las lesiones es uno de los principales cometidos de la labor pericial de los médicos forenses. Tras confirmarse la alteración de las características de las prótesis mamarias Poly Implant Prothèse (PIP, en adelante) que habían sido evaluadas por el organismo notificador para la obtención del marcado CE, y denunciarse el hecho, fue necesaria la valoración médico-legal de las lesiones producidas por la implantación de dichas prótesis. El objetivo principal de la presente investigación es dar respuesta a todos los aspectos médico-jurídicos necesarios para la compensación de las victimas afectadas por el hecho antijurídico investigado; Para ello se han establecido l…
Pterostilbene-induced tumor cytotoxicity: a lysosomal membrane permeabilization-dependent mechanism.
2012
The phenolic phytoalexin resveratrol is well known for its health-promoting and anticancer properties. Its potential benefits are, however, limited due to its low bioavailability. Pterostilbene, a natural dimethoxylated analog of resveratrol, presents higher anticancer activity than resveratrol. The mechanisms by which this polyphenol acts against cancer cells are, however, unclear. Here, we show that pterostilbene effectively inhibits cancer cell growth and stimulates apoptosis and autophagosome accumulation in cancer cells of various origins. However, these mechanisms are not determinant in cell demise. Pterostilbene promotes cancer cell death via a mechanism involving lysosomal membrane …
New evidence in one-lung ventilation
2017
Mechanical ventilation in thoracic surgery has undergone significant changes in recent years due to the implementation of the protective ventilation. This review will analyze recent ventilatory strategies in one-lung ventilation. A MEDLINE research was performed using Mesh term "One-Lung Ventilation" including randomized clinical trials, metanalysis, reviews and systematic reviews published in the last 6 years. Search was performed on 21st March 2017. A total of 75 articles were initially found. After title and abstract review 14 articles were included. Protective ventilation is not simply synonymous of low tidal volume ventilation, but it also includes routine use of PEEP and alveolar recr…
Bilateral thoracoscopic thymectomy using a novel positioning system.
2013
Several techniques of bilateral video-assisted thoracoscopic extended thymectomy have been proposed, and each has its own proponents. We summarize our experience in 20 patients who underwent bilateral video-assisted thoracoscopic extended thymectomy, using a new patient positioning that amplifies the thoracoscopic view of the cardiophrenic regions which are often difficult to visualize with standard techniques. In all cases, en-bloc thymectomy with complete dissection of the mediastinal fatty tissue was achieved without sternal retractors or additional incisions.
The use of video-assisted thoracic surgery in the management of Pancoast tumours
2010
We describe our experience using video-assisted thoracic surgery (VATS) as an adjunct to the surgical management of Pancoast tumors. Between March 2004 and November 2009, 13 patients with Pancoast tumors were included in this study. Surgery was performed by positioning the patient to allow either an anterior or a posterior thoracotomy. VATS was employed to explore the pleural cavity, to optimize the surgical access and as an assistance during surgical resection. Three patients with pleural carcinosis at thoracoscopy did not undergo further surgery. Seven lobectomies and three wedge resections were performed with an en bloc chest-wall resection and mediastinal lymphadenectomy. The surgical a…
A comparative analysis of Pancoast tumour resection performed via video-assisted thoracic surgery versus standard open approaches.
2014
OBJECTIVES: The aim of the present paper was to conduct a comparative analysis of outcomes after thoracoscopic resection versus standard thoracotomy approach in the treatment of Pancoast tumours. METHODS: All consecutive patients with Pancoast tumours undergoing surgical treatment from March 2000 to November 2012 were enrolled. Patients were divided into 2 groups according to whether a thoracoscopic or standard thoracotomy approach was adopted. In addition to morbidity and mortality, (i) intensity of pain; (ii) respiratory function focusing on the postoperative value and its variation with respect to the predicted value (Delta); (iii) analgesic consumption at different times during the post…
Symptomatic atherosclerotic occlusive disease of all supra-aortic arch vessels treated with total aortic arch rerouting.
2011
We present an uncommon case of symptomatic atherosclerotic occlusive disease of all supra-aortic arch vessels and its surgical treatment by total aortic arch rerouting after endarteriectomy of all target vessels.
