Inmunomedia 4.0: enseñando y aprendiendo Inmunología. Una experiencia interuniversitaria vertebrada en 4 ejes
El nuevo profesor-tutor desempeña competencias que incluyen el uso de las nuevas tecnologías, el diseño de Objetos de Aprendizaje Multimedia (OAM) y la supervisión del aprendizaje del alumnado. En este contexto, Inmunomedia 4.0 –proyecto en el que participan las Universidades de Valladolid, Alicante, Complutense y Toulouse III- pretende responder a necesidades y carencias en la docencia de la Inmunología en titulaciones Biomédicas: en primer lugar “Elaborando y difundiendo OAMs" de Inmunología de calidad, como la colección de “Inmunopíldoras” de gran impacto entre universitarios hispanoparlantes; en segundo lugar "Coleccionando OAMs en tablones" (“Content Curation”) que proporcionan a estudiantes y profesores información útil, etiquetada, contrastada y organizada por Módulos. De las diferentes herramientas de “content curation” utilizadas, las de mayor repercusión han sido las colecciones realizadas con “Scoop.it” y “Pinterest”; en tercer lugar "Implicando activamente a los estudiantes" de diferentes universidades en la elaboración de un “Periódico Universitario de Inmunología” tras emitir en twitter noticias de interés inmunológico usando hashtags, que se rastrean y generan un diario en “Paper.li”; y finalmente "Impulsando la tercera misión universitaria" elaborando materiales divulgativos multimedia de inmunología y difundiéndolos en redes sociales, a los pacientes e incluso en lugares públicos (colección de videos “Canal Defensas”)

El Sistema del Complemento, interactivo y magnético. Memoria final
El modelo didáctico más empleado en la enseñanza universitaria es de tipo transmisivo, centrado en la exposición del profesor/a con el apoyo de las presentaciones y los libros de texto, siendo el alumno/a esencialmente receptor de la enseñanza. Sin embargo, cada vez más se emplean estrategias alternativas para abordar el proceso de enseñanza-aprendizaje desde modelos más centrados en el alumno/a, que favorezcan su implicación, actividad y protagonismo.
Con el proyecto de innovación docente: El Sistema del Complemento, interactivo y magnético, queremos desarrollar una herramienta didáctica que nos permita implementar una estrategia de aprendizaje interactiva para el estudio de la cascada de activación del sistema del complemento.
La propuesta se ha programado para la asignatura de Fisiopatología del Complemento impartida en el Máster de Investigación en Inmunología (UCM).
Para ello, elaboramos material didáctico que consiste en fichas impresas en papel imantado que representan cada uno de los componentes que forman el sistema del complemento de manera que se puedan colocar y mover sobre una pizarra magnética. Este material se pone a disposición de los estudiantes para realizar actividades concretas propuestas por los profesores/as, en las que se trabaja en grupo y de forma interactiva, sirviendo también como herramienta para el repaso de conceptos y resolución de dudas durante las clases teóricas
Development and Evaluation of a Disease Large Animal Model for Preclinical Assessment of Renal Denervation Therapies
[EN] New-generation catheters-based renal denervation (RDN) is under investigation for the treatment of uncontrolled hypertension (HTN). We assessed the feasibility of a large animal model of HTN to accommodate the human RDN devices. Ten minipigs were instrumented to measure blood pressure (BP) in an awake-state. HTN was induced with subcutaneous 11-deoxycorticosterone (DOCA, 100 mg/kg) implants. Five months after, the surviving animals underwent RDN with the Symplicity® system. Norepinephrine (NE) renal gradients were determined before and 1 month after RDN. Renal arteries were processed for histological (hematoxylin-eosin, Movat pentachrome) and immunohistochemical (S100, tyrosine-hydroxylase) analyses. BP significantly rose after DOCA implants. Six animals died prematurely, mainly from infectious causes. The surviving animals showed stable BP levels after 5 months. One month after RDN, nerve damage was showed in three animals, with impedance drop >10%, NE gradient drop and reduction in BP. The fourth animal showed no nerve damage, impedance drop <10%, NE gradient increase and no change in BP. In conclusion, the minipig model of DOCA-induced HTN is feasible, showing durable effects. High mortality should be addressed in next iterations of this model. RDN may partially offset the DOCA-induced HTN. Impedance drop and NE renal gradient could be markers of RDN success.SIThis research was funded by Consejería de Salud, Junta de Castilla and Leon, Spain, the Grant GRS 1001/A/2014.We want to thank Medtronic Iberia for the donation of the Symplicity catheters used in this experiment

Estudio de los efectos de las lesiones del labrum acetabular en la cadera en un modelo experimental lagomorfo adulto
Objetivo: El cartílago labral es una estructura cartilaginosa que recubre el acetábulo de la cadera. Su lesión es
controvertida en cuanto a sus implicaciones debido a que no se conoce bien si es una causa de degeneración
articular o sólo un cambio degenerativo más. Hemos diseñado un modelo animal en conejo para estudiar esta
lesión.
Material y metodología: Se utilizaron tres grupos de 13 animales a los que se lesionó una cadera dejando la
otra como control y se les mantuvo estabulados al primer grupo 12 semanas, al segundo 18 y al tercero 30.
Posteriormente se les realizó un estudio radiológico, otro por resonancia magnética y, tras su sacrificio, un estudio
histológico.
Resultados: No encontramos relación en nuestro modelo entre la lesión labral y los cambios degenerativos posteriores
en los plazos citados. Tampoco encontramos daños labrales sin cicatrizar en el momento del sacrificio.
Conclusión: En el modelo animal lagomorfo, la lesión labral no produce cambios degenerativos artrósicos y el
cartílago labral podría presentar cierta capacidad de regeneración
Long COVID in hospitalized and non-hospitalized patients in a large cohort in Northwest Spain, a prospective cohort study
Survivors to COVID-19 have described long-term symptoms after acute disease. These signs constitute a heterogeneous group named long COVID or persistent COVID. The aim of this study is to describe persisting symptoms 6 months after COVID-19 diagnosis in a prospective cohort in the Northwest Spain. This is a prospective cohort study performed in the COHVID-GS. This cohort includes patients in clinical follow-up in a health area of 569,534 inhabitants after SARS-CoV-2/COVID-19 diagnosis. Clinical and epidemiological characteristics were collected during the follow up. A total of 248 patients completed 6 months follow-up, 176 (69.4%) required hospitalization and 29 (10.2%) of them needed critical care. At 6 months, 119 (48.0%) patients described one or more persisting symptoms. The most prevalent were: extra-thoracic symptoms (39.1%), chest symptoms (27%), dyspnoea (20.6%), and fatigue (16.1%). These symptoms were more common in hospitalized patients (52.3% vs. 38.2%) and in women (59.0% vs. 40.5%). The multivariate analysis identified COPD, women gender and tobacco consumption as risk factors for long COVID. Persisting symptoms are common after COVID-19 especially in hospitalized patients compared to outpatients (52.3% vs. 38.2%). Based on these findings, special attention and clinical follow-up after acute SARS-CoV-2 infection should be provided for hospitalized patients with previous lung diseases, tobacco consumption, and women
Abnormal Liver Function Test in Patients Infected with Coronavirus (SARS-CoV-2): A Retrospective Single-Center Study from Spain
The outbreak of the novel coronavirus SARS-CoV-2 epidemic has rapidly spread and still poses a serious threat to healthcare systems worldwide. In the present study, electronic medical records containing clinical indicators related to liver injury in 799 COVID-19-confirmed patients admitted to a hospital in Madrid (Spain) were extracted and analyzed. Correlation between liver injury and disease outcome was also evaluated. Serum levels of Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Gamma-glutamyltransferase (GGT), Alkaline phosphatase (ALP), Lactate dehydrogenase (LDH) and AST/ALT ratio were elevated above the Upper Limit of Normal (ULN) in 25.73%, 49.17%, 34.62%, 24.21%, 55.84% and 75% of patients, respectively. Interestingly, significant positive correlation between LDH levels and the AST/ALT ratio with disease outcome was found. Our data showed that SARS-CoV-2 virus infection leads to mild, but significant changes in serum markers of liver injury. The upregulated LDH levels as well as AST/ALT ratios upon admission may be used as additional diagnostic characteristic for COVID-19 patients
Role of age and comorbidities in mortality of patients with infective endocarditis
[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality.
[Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk.
[Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality.
[Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
