    A cross-sectional study was conducted to assess the circulation and risk factors associated with West Nile virus (WNV) exposure in equine and wild bird populations following the largest epidemic outbreak ever reported in Spain. A total of 305 equids and 171 wild birds were sampled between November 2020 and June 2021. IgG antibodies against flaviviruses were detected by blocking enzyme-linked immunosorbent assay (bELISA) in 44.9% (109/243) and 87.1% (54/62) of unvaccinated and vaccinated equids, respectively. The individual seroprevalence in unvaccinated individuals (calculated on animals seropositive by both bELISA and virus microneutralization test [VNT]) was 38.3% (95%CI: 33.1–43.4). No IgM antibodies were detected in animals tested (0/243; 0.0%; 95%CI: 0.0–1.5) by capture-ELISA. The main risk factors associated with WNV exposure in equids were age (adult and geriatric), breed (crossbred) and the absence of a disinsection programme on the facilities. In wild birds, IgG antibodies against flaviviruses were found in 32.7% (56/171; 95%CI: 26.8–38.6) using bELISA, giving an individual WNV seroprevalence of 19.3% (95%CI: 14.3–24.3) after VNT. Seropositivity was found in 37.8% of the 37 species analysed. Species group (raptors), age (>1-year old) and size (large) were the main risk factors related to WNV seropositivity in wild birds. Our results indicate high exposure and widespread distribution of WNV in equid and wild bird populations in Spain after the epidemic outbreak in 2020. The present study highlights the need to continue and improve active surveillance programmes for the detection of WNV in Spain, particularly in those areas at greatest risk of virus circulation

    Grupo de Trabajo en Nefrología Diagnóstica e Intervencionista (GNDI) de la Sociedad Española de Nefrología (SEN).[ES] La ecografía es una herramienta esencial en el manejo del paciente nefrológico que permite el diagnóstico, el seguimiento y la realización de intervencionismo sobre el riñón. La utilidad de los ultrasonidos en Nefrología no se circunscribe exclusivamente al estudio ecográfico del riñón. Mediante ecografía el nefrólogo puede, además, optimizar el manejo de la fístula arteriovenosa para hemodiálisis, medir el riesgo cardiovascular (grosor íntima-media), implantar catéteres centrales para hemodiálisis ecoguiados y ayudar en la colocación de los peritoneales, así como calcular la volemia del paciente mediante ecografía cardiaca básica, ecografía de la vena cava inferior y pulmonar. Desde el Grupo de Trabajo en Nefrología Diagnóstica e Intervencionista (GNDI) de la Sociedad Española de Nefrología (SEN) hemos elaborado este documento de consenso en el que se resumen las principales aplicaciones de la ecografía en Nefrología, incluyendo los requisitos técnicos básicos necesarios, el marco normativo y el nivel de capacitación de los nefrólogos en esta materia. El objetivo de este trabajo es promover la inclusión de la ecografía, tanto diagnóstica como intervencionista, en la práctica clínica habitual del nefrólogo y en la cartera de servicios de Nefrología con la finalidad de ofrecer un manejo diligente, eficiente e integral al paciente nefrológico.[EN] Ultrasound is an essential tool in the management of the nephrological patient allowing the diagnosis, monitoring and performance of kidney intervention. However, the usefulness of ultrasound in the hands of the nephrologist is not limited exclusively to the ultrasound study of the kidney. By ultrasound, the nephrologist can also optimize the management of arteriovenous fistula for hemodialysis, measure cardiovascular risk (mean intimate thickness), implant central catheters for ultrasound-guided HD, as well as the patient's volemia using basic cardiac ultrasound, ultrasound of the cava inferior vein and lungs. From the Working Group on Interventional Nephrology (GNDI) of the Spanish Society of Nephrology (SEN) we have prepared this consensus document that summarizes the main applications of ultrasound to Nephrology, including the necessary basic technical requirements, the framework normative and the level of training of nephrologists in this area. The objective of this work is to promote the inclusion of ultrasound, both diagnostic and interventional, in the usual clinical practice of the nephrologist and in the Nephrology Services portfolio with the final objective of offering diligent, efficient and comprehensive management to the nephrological patient

    Tunneled catheter-related bacteremia in hemodialysis patients: incidence, risk factors and outcomes. A 14-year observational study

    [Background] Tunneled catheter-related bacteremia represents one of the major complications in patients on hemodialysis, and is associated with increased morbidity and mortality. This study aimed to evaluate the incidence of tunneled catheter-related bacteremia and, secondly, to identify possible factors involved in the first episode of bacteremia.[Methods] This is a retrospective study of all tunneled catheters inserted between 1 January, 2005 and 31 December, 2019. Data on patients with a tunneled catheter were analyzed for comorbidities, catheter characteristics, microbiological culture results and variables related to the first episode of bacteremia. Patient outcomes were also assessed.[Results] In the 14-year period under study, 406 tunneled catheters were implanted in 325 patients. A total of 85 cases of tunneled catheter-related bacteremia were diagnosed, resulting in an incidence of 0.40 per 1000 catheter days (81.1% after 6 months of implantation). The predominant microorganisms isolated were Gram-positive organisms: Staphylococcus epidermidis (48.4%); Staphylococcus aureus (28.0%). We found no significant differences in time to catheter removal for infections or non-infection-related reasons. The jugular vein, the Palindrome® catheter, and being the first vascular access were protective factors for the first episode of bacteremia. The 30-day mortality rate from the first tunneled catheter-related bacteremia was 8.7%.[Conclusions] The incidence of bacteremia in our study was low and did not seem to have a relevant impact on catheter survival. S. epidermidis was the most frequently isolated microorganism, followed by S. aureus. We identified Palindrome® catheter, jugular vein, and being the first vascular access as significant protective factors against tunneled catheter-related bacteremia.FISEVI (Andalusian Public Foundation for the Management of Health Research in Seville) paid the fees for publication.Peer reviewe

    Coordinadora: Rocío Fernández Urrusuno. Co-coordinadora: Carmen Serrano Martino.YesEstas guías son un recurso indispensable en los Programas de Optimización de Antibióticos (PROA). No sólo constituyen una herramienta de ayuda para la toma de decisiones en los principales síndromes infecciosos, proporcionando recomendaciones para el abordaje empírico de dichos procesos, sino que son el patrón/estándar de referencia que permitirá determinar la calidad o adecuación de los tratamientos realizados. Las guías pueden ser utilizadas, además, como herramienta de base para la formación y actualización en antibioterapia, ya que permiten mantener actualizados los conocimientos sobre las nuevas evidencias en el abordaje de las infecciones. Por último, deberían incorporar herramientas que faciliten el proceso de toma de decisiones compartidas con el paciente. El objetivo de esta guía es proporcionar recomendaciones para el abordaje de las enfermedades infecciosas más prevalentes en la comunidad, basadas en las últimas evidencias disponibles y los datos de resistencias de los principales patógenos que contribuyan a mejorar la calidad de la prescripción de antimicrobianos
