Nephroprotection and iodinate contrast medias.

The incidence of post-contrast acute kidney injury (PC-AKI) is low with the new low- or iso-osmolar non-ionic iodinated contrast agents. The only proven form of prophylaxis for PC-AKI is hydration, preferably intravenous, although oral hydration is equally effective. In this article we define PC-AKI and its risk factors, propose a prophylaxis protocol and respond to the most common doubts that arise around prophylaxis.

Diagnosis and Treatment of Renal ANCA Vasculitis: A Summary of the Consensus Document of the Catalan Group for the Study of Glomerular Diseases (GLOMCAT).

The document provides a comprehensive overview of the diagnosis, monitoring, and treatment of anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) with renal involvement, focusing on granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). It outlines the definitions, clinical presentation, histopathological classification, monitoring strategies, induction and maintenance treatments, as well as special considerations for relapsing, refractory, and frail patients with renal AAV. The document was prepared by the Catalan Group for the Study of Glomerular Diseases (GLOMCAT), which comprises nephrologists with extensive experience in the diagnosis and treatment of AAV patients.

The real-world use and effectiveness of avacopan in routine practice for the treatment of ANCA vasculitis. First experiences in Spain.

Objectives: ANCA-associated vasculitis (AAV) are chronic diseases with relapses that associate organic damage because of the disease and its treatment. Avacopan is a new treatment indicated for AAV. We present the first experiences with avacopan in Spain as part of an Early Access program.

Phosphoramide Hydrogels as Biodegradable Matrices for Inkjet Printing and Their Nano-Hydroxyapatite Composites.

Inkjet printing is a leading technology in the biofabrication of three-dimensional biomaterials, offering digital, noncontact deposition with micron-level precision. Among these materials, hydroxyapatite is widely recognized for its use in bone tissue engineering. However, most hydroxyapatite-laden inks are unsuitable for inkjet printing.
