Evaluación funcional tras SARS-CoV-2 crítico. Estudio de cohortes de la unidad de rehabilitación en un hospital de tercer nivel / Functional evaluation in patient with critical SARS-CoV-2 disease: Cohort study in a third level hospital rehabilitation unit

Introducción: La neumonía por SARS-CoV-2 es una enfermedad infecciosa respiratoria altamente contagiosa que causa disfunción respiratoria, física y psicológica. Presentamos resultados de los pacientes valorados por el Servicio de Rehabilitación al alta de UCI por SARS-CoV-2. Material y método: Estudio de cohortes de pacientes ingresados en UCI por neumonía por SARS-CoV-2 desde el 01/10/2020 al 31/07/2021. Recogemos datos sociodemográficos, antecedentes personales, estancia media en UCI y hospital, Barthel, marcha (FAC) y mMRC (preingreso/valoración inicial/alta), desarrollo de patología osteomuscular y/o neurológica y necesidad de tratamiento rehabilitador. Resultados: Muestra de 341 pacientes de los cuales 224 cumplen criterios. Edad media: 63 años (68,75% hombres). Estancia media UCI/hospital: 27/44 días. Valorados por médicos rehabilitadores, facilitamos a los pacientes una guía elaborada por el equipo médico resolviendo dudas del proceso y pautando ejercicios de intensidad y dificultad progresiva, a realizar durante el ingreso y en el domicilio. El 42,86% desarrolló patología neurológica (83,33% del sistema nervioso periférico). El 100% ha realizado fisioterapia respiratoria y el 72,32% ha precisado fisioterapia motora. Conclusiones: En nuestro estudio, un elevado número de pacientes han precisado tratamiento rehabilitador para su recuperación funcional, destacando el desarrollo de patología neurológica post-COVID. El SARS-CoV-2 genera otras complicaciones, no solo respiratorias, subsidiarias de valorarse y tratarse por los Servicios de Rehabilitación para una recuperación integral que minimice las secuelas.(AU)

Introduction: SARS-COV-2 pneumonia is a highly contagious respiratory disease that causes respiratory, physical and psychological dysfunctions. We present the results of patient assessment when they were discharged from the ICU. Material and method: Cohort study of patients affected by SARS-COV-2 pneumonia admitted to the intensive care unit from 01/10/2020 to 31/07/2021. We collect sociodemographic data, personal history, ICU and hospital stay, Barthel, FAC and mMRC (pre-admission/initial assessment/discharge), development of osteomuscular and/or neurological pathology and need for rehabilitation treatment. Results: A total of 341 patients were evaluated, of which 224 met criteria. The average age was 63 years (68.75% men). Mean ICU/hospital stay were 27/44 days. They were assessed by physiatry, after that, we provide a guide developed by physiatry, solving doubts about the disease and setting exercises of intensity and progressive difficulty, to be carried out during the admission and at home. Neurological pathology was present at 42.86% patients, of whom a 83.33% were peripheral nervous system disease.

Regulatory and metabolic adaptations in the nitrogen assimilation of marine picocyanobacteria.

Prochlorococcus and Synechococcus are the two most abundant photosynthetic organisms on Earth, with a strong influence on the biogeochemical carbon and nitrogen cycles. Early reports demonstrated the streamlining of regulatory mechanisms in nitrogen metabolism and the removal of genes not strictly essential. The availability of a large series of genomes, and the utilization of latest generation molecular techniques have allowed elucidating the main mechanisms developed by marine picocyanobacteria to adapt to the environments where they thrive, with a particular interest in the strains inhabiting oligotrophic oceans. Given that nitrogen is often limited in those environments, a series of studies have explored the strategies utilized by Prochlorococcus and Synechococcus to exploit the low concentrations of nitrogen-containing molecules available in large areas of the oceans. These strategies include the reduction in the GC and the cellular protein contents; the utilization of truncated proteins; a reduced average amount of N in the proteome; the development of metabolic mechanisms to perceive and utilize nanomolar nitrate concentrations; and the reduced responsiveness of key molecular regulatory systems such as NtcA to 2-oxoglutarate. These findings are in sharp contrast with the large body of knowledge obtained in freshwater cyanobacteria. We will outline the main discoveries, stressing their relevance to the ecological success of these important microorganisms.

Mixotrophy in marine picocyanobacteria: use of organic compounds by Prochlorococcus and Synechococcus.

Marine picocyanobacteria of the Prochlorococcus and Synechococcus genera have been longtime considered as autotrophic organisms. However, compelling evidence published over the last 15 years shows that these organisms can use different organic compounds containing key elements to survive in oligotrophic oceans, such as N (amino acids, amino sugars), S (dimethylsulfoniopropionate, DMSP), or P (ATP). Furthermore, marine picocyanobacteria can also take up glucose and use it as a source of carbon and energy, despite the fact that this compound is devoid of limiting elements and can also be synthesized by using standard metabolic pathways. This review will outline the main findings suggesting mixotrophy in the marine picocyanobacteria Prochlorococcus and Synechococcus, and its ecological relevance for these important primary producers.

Antimicrobial Activity of a Cationic Guanidine Compound against Two Pathogenic Oral Bacteria.

This study evaluated the potential antimicrobial properties of a polyguanidine (CatDex) on two oral bacteria. Chlorhexidine gluconate 1340 µmoL L-1 (CHX 0.12%) was used as control. Streptococcus mutans (S. mutans) and Porphyromonas gingivalis (P. gingivalis) were grown in BHI media. Bacterial sensitivity and antimicrobial activity were determined by the minimum inhibitory concentration (MIC) and Kirby-Bauer methods. To study side effects, that is, toxicity, dental pulp stem cells (DPSCs) were used. Fluorometric cytotoxicity and confocal microscopy assays were used in order to test cell viability. CatDex inhibited growth of S. mutans at all concentrations and growth of P. gingivalis at all concentrations except 25 µmoL L-1. The MIC of CatDex was 50 µmoL L-1 for both S. mutans and P. gingivalis. The inhibition of bacteria exposed for 8 h at 50 µmoL L-1 of CatDex exhibited increased antimicrobial activity over time, with 91% inhibition in both bacteria. The antimicrobial activities of CatDex and CHX were similar when tested on two common bacteria. CatDex was significantly less toxic to DPSCs. CatDex toxicity depended on time and not on concentration. With regard to clinical relevance, CatDex may have potential as a novel antimicrobial agent. Further studies are in progress.

Recomendaciones sobre rehabilitación cardíaca en la cardiopatía isquémica de la Sociedad de Rehabilitación Cardio-Respiratoria (SORECAR) / Recommendations of the Cardio-Respiratory Rehabilitation Society (SORECAR) on cardiac rehabilitation in ischemic heart disease

La cardiopatía isquémica supone la mayor causa de muerte en España y en el mundo occidental. El programa de rehabilitación cardíaca engloba todas las medidas para realizar prevención secundaria en estos pacientes y mejorar la morbimortalidad. Es un programa eficaz, pero su implementación es escasa y variable, siendo inferior al 5% en España, por lo que se debería priorizar estrategias para facilitar la realización de estos programas. Un grupo de expertos fue nombrado por la Sociedad Española de Rehabilitación Cardio-Respiratoria (SORECAR) para realizar una revisión de todas las evidencias disponibles en rehabilitación cardíaca y elaborar un documento aplicándolo a la práctica clínica. El resultado ha sido la elaboración final de un protocolo de actuación en rehabilitación cardíaca, con instrucciones o recomendaciones a modo de resumen. Contiene aspectos sobre rehabilitación cardíaca para disminuir la variabilidad entre dichas Unidades y crear las bases para una adecuada acreditación de Unidades de Rehabilitación Cardíaca (AU)

Ischemic heart disease is the largest cause of death in Spain and the Western world. Cardiac rehabilitation programs encompass all the measures necessary for secondary prevention in these patients and to improve morbidity and mortality. These programs are effective, but their implementation is low and variable, being less than 5% in Spain. Consequently, priority should be given to strategies that facilitate the implementation of these programs. A group of experts was appointed by the Cardio-Respiratory Rehabilitation Society (SORECAR) to review all the available evidence on cardiac rehabilitation and apply it to develop a clinical practice document. The end result was the development of a protocol for cardiac rehabilitation, with instructions or summarized recommendations. The document discusses aspects of cardiac rehabilitation that reduce variation among these units and provides a basis for proper accreditation of cardiac rehabilitation units (AU)

Gestión del conocimiento I: formación universitaria, especializada y formación continuada / Management of knowledge I: university, specializaed training and continuing education

La actividad desarrollada por profesionales y docentes universitarios es primordial para establecer los cauces que coordinen el sistema sanitario y universitario. Las unidades de gestión clínica (UGC) deben promover la participación del profesional en el ámbito asistencial, de gestión, docente e investigador. En la Universidad de Sevilla, la asignatura de principios de medicina física y rehabilitación (MEFYR), vinculada al área de conocimiento de radiología y medicina física, es impartida por 8 profesores especialistas en MEFYR. Una de las máximas preocupaciones de los facultativos dedicados a la MEFYR es la formación de nuevos especialistas. La UGC de Rehabilitación lleva a cabo su actividad docente mediante el desarrollo de un programa tutelado para los residentes, con unos contenidos específicos de formación teóricos (sesión clínica tipo Critical Apraisal Topics [CAT], sesiones clásicas y bibliográficas) y prácticos (manipulaciones). La formación continuada es un proceso de enseñanza y aprendizaje activo y permanente destinado a actualizar y mejorar los conocimientos, habilidades y actitudes de los profesionales sanitarios. La UGC de Rehabilitación, a través de la Comisión de Docencia, organiza e imparte cursos anuales de formación continuada de 30 horas lectivas, contribuyendo a la difusión y conocimiento de nuestra especialidad. Consideramos que las UGC, en el plano docente y formativo, nos proporcionan las herramientas necesarias para mejorar el conocimiento y la calidad de la formación. Desde estas unidades se incentiva: participar en la docencia universitaria, elaborar tesis doctorales y contribuir a la formación especializada y continuada. Se promueven las publicaciones en revistas de impacto y la investigación (AU)

The activity developed by professionals and university teachers is essential to establish the pathways that coordinate the health care and university system. The Clinical Management Units (CMU) should promote the participation of the professional in the areas of care, management, teaching and investigator. In the University of Seville, eight professors who are specialized in Physical and Rehabilitation Medicine Principles (PRMP) teach the subjects of (PRMP) link to the area of knowledge of Radiology and Physical Medicine is given by. One of the maximum concerns of the professionals dedicated to the PRMP is the training of new specialists. The CMU of rehabilitation performs its teaching activities through the development of a tutelary program for the residents, with some specific contents on theoretical training (clinical session type Critical Appraisal Topics (CAT), classical sessions and be a graphical ones) unpractical training (manipulations). The continuing education is an active and permanent teaching and learning process aimed at updating and improving knowledge, skills and attitudes of the health care professionals. The CMU of Rehabilitation, through the Teaching Committee, organizes and gives yearly courses on continuing education with 13 teaching hours contributing to the spreading and knowledge of our specialty (AU)
