COVID-19; Atrial fibrillation; EdoxabanCOVID-19; Fibrilación auricular; EdoxabanCOVID-19; Fibril·lació auricular; EdoxabanObjective During the first wave of the SARS-CoV-2 pandemic, management of anticoagulation therapy in hospitalized patients with atrial fibrillation (AF) was simplified to low-molecular-weight heparin (LMWH) followed by oral anticoagulation, mainly owing to the risk of drug–drug interactions. However, not all oral anticoagulants carry the same risk. Methods Observational, retrospective, and multicenter study that consecutively included hospitalized patients with AF anticoagulated with LMWH followed by oral anticoagulation or edoxaban concomitantly with empirical COVID-19 therapy. Time-to-event (mortality, total bleeds, and admissions to ICU) curves, using an unadjusted Kaplan-Meier method and Cox regression model adjusted for potential confounders were constructed. Results A total of 232 patients were included (80.3 ± 7.7 years, 50.0% men, CHA2DS2-VASc 4.1 ± 1.4; HAS-BLED 2.6 ± 1.0). During hospitalization, patients were taking azithromycin (98.7%), hydroxychloroquine (89.7%), and ritonavir/lopinavir (81.5%). The mean length of hospital stay was 14.6 ± 7.2 days, and total follow-up was 31.6 ± 13.4 days; 12.9% of patients required admission to ICU, 18.5% died, and 9.9% had a bleeding complication (34.8% major bleeding). Length of hospital stay was longer in patients taking LMWH (16.0 ± 7.7 vs 13.3 ± 6.5 days; P = .005), but mortality and total bleeds were similar in patients treated with edoxaban and those treated with LMWH followed by oral anticoagulation. Conclusions Mortality rates, arterial and venous thromboembolic complications, and bleeds did not significantly differ between AF patients receiving anticoagulation therapy with edoxaban or LMWH followed by oral anticoagulation. However, the duration of hospitalization was significantly lower with edoxaban. Edoxaban had a similar therapeutic profile to LMWH followed by oral anticoagulation and may provide additional benefits

Impact of New Onset Atrial Fibrillation in Hospitalized Patients with COVID-19: Results of the “ACO-VID” Registry

COVID-19; Anticoagulation; Atrial fibrillationCOVID-19; Anticoagulación; Fibrilación auricularCOVID-19; Anticoagulació; Fibril·lació auricularObjective To assess the impact of new-onset atrial fibrillation (AF) on patients hospitalized with coronavirus disease 2019 (COVID-19). Methods Multicenter and retrospective study that included subjects >55 years hospitalized with COVID-19 from March to October 2020 in Spanish hospitals. Patients were divided into 3 groups (no AF, new-onset AF, and preexisting AF) and followed-up to 90 days. Results A total of 668 patients were included, of whom 162 (24.3%) had no AF, 107 (16.0%) new-onset AF and 399 (59.7%) preexisting AF. Compared to patients without AF, those patients with new-onset AF were older and had more comorbidities, but without differences with preexisting AF. During hospitalization, in the univariate analysis, compared to patients without AF, major bleeding and cardiovascular mortality were more frequent in patients with new-onset AF (10.3% vs 0.6%; P < .001; 2.8% vs 0.6%; P = .025, respectively), with a trend toward more stroke (1.9% vs 0%; P = .085). Outcomes were similar between AF groups, but the length of stay was greater in preexisting AF patients. Among patients with new-onset AF taking reduced doses of anticoagulant treatment was associated with higher risks of stroke and major bleeding. Conclusions In COVID-19 hospitalized patients, new-onset AF may be associated with worse outcomes, but influenced by the dose of anticoagulants.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the Fundación para la Formación e Investigación Sanitarias de la Región de Murcia, though an unrestricted grant from Daichii Sankyo (DS) Spain.

CARB-ES-19 Multicenter Study of Carbapenemase-Producing Klebsiella pneumoniae and Escherichia coli From All Spanish Provinces Reveals Interregional Spread of High-Risk Clones Such as ST307/OXA-48 and ST512/KPC-3

Objectives: CARB-ES-19 is a comprehensive, multicenter, nationwide study integrating whole-genome sequencing (WGS) in the surveillance of carbapenemase-producing K. pneumoniae (CP-Kpn) and E. coli (CP-Eco) to determine their incidence, geographical distribution, phylogeny, and resistance mechanisms in Spain. Methods: In total, 71 hospitals, representing all 50 Spanish provinces, collected the first 10 isolates per hospital (February to May 2019); CPE isolates were first identified according to EUCAST (meropenem MIC > 0.12 mg/L with immunochromatography, colorimetric tests, carbapenem inactivation, or carbapenem hydrolysis with MALDI TOF). Prevalence and incidence were calculated according to population denominators. Antibiotic susceptibility testing was performed using the microdilution method (EUCAST). All 403 isolates collected were sequenced for high-resolution single nucleotide polymorphism (SNP) typing, core genome multilocus sequence typing (cgMLST), and resistome analysis. Results: In total, 377 (93.5%) CP-Kpn and 26 (6.5%) CP-Eco isolates were collected from 62 (87.3%) hospitals in 46 (92%) provinces. CP-Kpn was more prevalent in the blood (5.8%, 50/853) than in the urine (1.4%, 201/14,464). The cumulative incidence for both CP-Kpn and CP-Eco was 0.05 per 100 admitted patients. The main carbapenemase genes identified in CP-Kpn were blaOXA−48 (263/377), blaKPC−3 (62/377), blaVIM−1 (28/377), and blaNDM−1 (12/377). All isolates were susceptible to at least two antibiotics. Interregional dissemination of eight high-risk CP-Kpn clones was detected, mainly ST307/OXA-48 (16.4%), ST11/OXA-48 (16.4%), and ST512-ST258/KPC (13.8%). ST512/KPC and ST15/OXA-48 were the most frequent bacteremia-causative clones. The average number of acquired resistance genes was higher in CP-Kpn (7.9) than in CP-Eco (5.5). Conclusion: This study serves as a first step toward WGS integration in the surveillance of carbapenemase-producing Enterobacterales in Spain. We detected important epidemiological changes, including increased CP-Kpn and CP-Eco prevalence and incidence compared to previous studies, wide interregional dissemination, and increased dissemination of high-risk clones, such as ST307/OXA-48 and ST512/KPC-3

Prognostic impact of circulating plasma cells in patients with multiple myeloma : implications for plasma cell leukemia definition

The presence of circulating plasma cells in patients with multiple myeloma is considered a marker for highly proliferative disease. In the study herein, the impact of circulating plasma cells assessed by cytology on survival of patients with multiple myeloma was analyzed. Wright-Giemsa stained peripheral blood smears of 482 patients with newly diagnosed myeloma or plasma cell leukemia were reviewed and patients were classified into 4 categories according to the percentage of circulating plasma cells: 0%, 1-4%, 5-20%, and plasma cell leukemia with the following frequencies: 382 (79.2%), 83 (17.2%), 12 (2.5%) and 5 (1.0%), respectively. Median overall survival according to the circulating plasma cells group was 47, 50, 6 and 14 months, respectively. At multivariate analysis, the presence of 5 to 20% circulating plasma cells was associated with a worse overall survival (relative risk 4.9, 95% CI 2.6-9.3) independently of age, creatinine, the Durie-Salmon system stage and the International Staging System (ISS) stage. Patients with ≥5% circulating plasma cells had lower platelet counts (median 86×10 9 /L vs. 214×10 9 /L, P <0.0001) and higher bone marrow plasma cells (median 53% vs. 36%, P =0.004). The presence of ≥5% circulating plasma cells in patients with multiple myeloma has a similar adverse prognostic impact as plasma cell leukemia

Jornadas Nacionales de Robótica y Bioingeniería 2023: Libro de actas

Las Jornadas de Robótica y Bioingeniería de 2023 tienen lugar en la Escuela Técnica Superior de Ingeniería Industrial de la Universidad Politécnica de IVIadrid, entre los días 14 y 16 de junio de 2023. En este evento propiciado por el Comité Español de Automática (CEA) tiene lugar la celebración conjunta de las XII Jornadas Nacionales de Robótica y el XIV Simposio CEA de Bioingeniería. Las Jornadas Nacionales de Robótica es un evento promovido por el Grupo Temático de Robótica (GTRob) de CEA para dar visibilidad y mostrar las actividades desarrolladas en el ámbito de la investigación y transferencia tecnológica en robótica. Asimismo, el propósito de Simposio de Bioingeniería, que cumple ahora su decimocuarta dicción, es el de proporcionar un espacio de encuentro entre investigadores, desabolladores, personal clínico, alumnos, industriales, profesionales en general e incluso usuarios que realicen su actividad en el ámbito de la bioingeniería. Estos eventos se han celebrado de forma conjunta en la anualidad 2023. Esto ha permitido aunar y congregar un elevado número de participantes tanto de la temática robótica como de bioingeniería (investigadores, profesores, desabolladores y profesionales en general), que ha posibilitado establecer puntos de encuentro, sinergias y colaboraciones entre ambos. El programa de las jornadas aúna comunicaciones científicas de los últimos resultados de investigación obtenidos, por los grupos a nivel español más representativos dentro de la temática de robótica y bioingeniería, así como mesas redondas y conferencias en las que se debatirán los temas de mayor interés en la actualidad. En relación con las comunicaciones científicas presentadas al evento, se ha recibido un total de 46 ponencias, lo que sin duda alguna refleja el alto interés de la comunidad científica en las Jornadas de Robótica y Bioingeniería. Estos trabajos serán expuestos y presentados a lo largo de un total de 10 sesiones, distribuidas durante los diferentes días de las Jornadas. Las temáticas de los trabajos cubren los principales retos científicos relacionados con la robótica y la bioingeniería: robótica aérea, submarina, terrestre, percepción del entorno, manipulación, robótica social, robótica médica, teleoperación, procesamiento de señales biológicos, neurorehabilitación etc. Confiamos, y estamos seguros de ello, que el desarrollo de las jornadas sea completamente productivo no solo para los participantes en las Jornadas que podrán establecer nuevos lazos y relaciones fructíferas entre los diferentes grupos, sino también aquellos investigadores que no hayan podido asistir. Este documento que integra y recoge todas las comunicaciones científicas permitirá un análisis más detallado de cada una de las mismas
