Ibero-American Society of Interventionism (SIDI) and the Spanish Society of Vascular and Interventional Radiology (SERVEI) Standard of Practice (SOP) for the management of inferior Vena Cava filters in the treatment of acute venous Thromboembolism

Objectives: to present an interventional radiology standard of practice on the use of inferior vena cava filters (IVCFs) in patients with or at risk to develop venous thromboembolism (VTE) from the Iberoamerican Interventional Society (SIDI) and Spanish Vascular and Interventional Radiology Society (SERVEI). Methods: a group of twenty-two interventional radiologist experts, from the SIDI and SERVEI societies, attended online meetings to develop a current clinical practice guideline on the proper indication for the placement and retrieval of IVCFs. A broad review was undertaken to determine the participation of interventional radiologists in the current guidelines and a consensus on inferior vena cava filters. Twenty-two experts from both societies worked on a common draft and received a questionnaire where they had to assess, for IVCF placement, the absolute, relative, and prophylactic indications. The experts voted on the different indications and reasoned their decision. Results: a total of two-hundred-thirty-three articles were reviewed. Interventional radiologists participated in the development of just two of the eight guidelines. The threshold for inclusion was 100% agreement. Three absolute and four relative indications for the IVCF placement were identified. No indications for the prophylactic filter placement reached the threshold. Conclusion: interventional radiologists are highly involved in the management of IVCFs but have limited participation in the development of multidisciplinary clinical practice guidelines

Conditional probability problems in textbooks an example from Spain

In this paper we show part of the results of a larger study that investigates conditional probability problem solving. In particular, we report on a structure-based method to identify, classify and analyse ternary problems of conditional probability in mathematics textbooks in schools. This method is also based on a realistic mathematics education approach to mathematics teaching through problem solving in context. We report some results of the analysis of mathematics textbooks from Spain

The Rho family member RhoE interacts with Skp2 and is degraded at the proteasome during cell cycle progression

RhoE/Rnd3 is an atypical member of the Rho family of small GTPases. In addition to regulating actin cytoskeleton dynamics, RhoE is involved in the regulation of cell proliferation, survival, and metastasis. We examined RhoE expression levels during cell cycle and investigated mechanisms controlling them. We show that RhoE accumulates during G1, in contact-inhibited cells, and when the Akt pathway is inhibited. Conversely, RhoE levels rapidly decrease at the G1/S transition and remain low for most of the cell cycle. We also show that the half-life of RhoE is shorter than that of other Rho proteins and that its expression levels are regulated by proteasomal degradation. The expression patterns of RhoE overlap with that of the cell cycle inhibitor p27. Consistently with an involvement of RhoE in cell cycle regulation, RhoE and p27 levels decrease after overexpression of the F-box protein Skp2. We have identified a region between amino acids 231 and 240 of RhoE as the Skp2-interacting domain and Lys(235) as the substrate for ubiquitylation. Based on our results, we propose a mechanism according to which proteasomal degradation of RhoE by Skp2 regulates its protein levels to control cellular proliferatio

COVID-19 Outbreak: Infection Control and Management Protocol for Vascular and Interventional Radiology Departments-Consensus Document.

COVID-19 (SARS-CoV-2 virus) pandemic was recently declared by the WHO as a global health emergency. A group of interventional radiology senior experts developed a consensus document for infection control and management of patients with COVID-19 in interventional radiology (IR) departments. This consensus statement has been brought together at short notice with the help of different protocols developed by governmental entities and scientific societies to be adapted to the current reality and needs of IR Departments. Recommendations are the specific strategies to follow in IR departments, preventive measures and regulations, step by step for donning and doffing personal protective equipment, specific IR procedures which can not be delayed, and aerosol-generating procedures in IR with COVID-19 patients. It is advisable with this document to be adapted to local workplace policies
