Resumen: El virus, además de provocar una pandemia, con centenares de miles de enfermos y con decenas de miles de fallecidos, ha tenido la capacidad («el poder») de romper las prácticas educativas ...estándar.Esto ha tenido, o puede tener, un beneficio: reconsiderar lo que es realmente importante y lo que no lo es tanto. Y eso tiene un gran valor para el docente y para el discente. Y también ha servido para reconocer y encontrar formas alternativas con las que se puede transmitir el saber. En definitiva, el profesor ha tenido la oportunidad de contribuir a crear un modelo educativo capaz de impulsar el desarrollo de nuevas formas y métodos de aprendizaje. Ciertas técnicas y recursos educativos han podido ser reconocidos como «presentes» o «ausentes» de nuestro sistema educativo.Esto implica que ciertos recursos han de estar presentes, o que es preciso optimizar los que ya están disponibles para enseñar, para aprender, o para evaluar. La tecnología permite facilitar el contacto «directo» entre profesor y alumno, entre profesores, y entre alumnos. Pero sobra decir que la tecnología ha de estar disponible. Abstract: The virus, besides causing a pandemic, with hundreds of thousands ill, and with tens of thousands dead, has had the ability (‘the power’) to break standard education practices. This has had, or may have, one benefit: to reconsider that which is really important and that which is not so important. And this is of great value for the teacher and for the student. And it has also served to recognise and find alternative ways to transmit the knowledge.All things considered, the teacher has had the opportunity to contribute in creating an education model capable of boosting the development of new ways and methods of learning. Certain educational techniques and resources have been able to be recognised as ‘present’ or ‘absent’ in our education system.This implies that certain recourses have to be present, or that is required to optimise those that are available in order to teach, to learn, or to evaluate. Technology helps to provide ‘direct’ contact between teacher and student, between teachers and between students. But it goes without saying that the technology has to be available.
This study aimed to validate the role of the D-dimer to lymphocyte ratio (DLR) for mortality prediction in a large national cohort of hospitalized coronavirus disease 2019 (COVID-19) patients.
A ...retrospective, multicenter, observational study that included hospitalized patients due to SARS-CoV-2 infection in Spain was conducted from March 2020 to March 2022. All biomarkers and laboratory indices analyzed were measured once at admission.
A total of 10,575 COVID-19 patients were included in this study. The mean age of participants was 66.9 (±16) years, and 58.6% (6202 patients) of them were male. The overall mortality rate was 16.3% (
= 1726 patients). Intensive care unit admission was needed in 10.5% (
= 1106 patients), non-invasive mechanical ventilation was required in 8.8% (
= 923 patients), and orotracheal intubation was required in 7.5% (789 patients). DLR presented a c-statistic of 0.69 (95% CI, 0.68-0.71) for in-hospital mortality with an optimal cut-off above 1. Multivariate analysis showed an independent association for in-hospital mortality for DLR > 1 (adjusted OR 2.09, 95% CI 1.09-4.04;
= 0.03); in the same way, survival analysis showed a higher mortality risk for DLR > 1 (HR 2.24; 95% CI 2.03-2.47;
< 0.01). Further, no other laboratory indices showed an independent association for mortality in multivariate analysis.
This study confirmed the usefulness of DLR as a prognostic biomarker for mortality associated with SARS-CoV-2 infection, being an accessible, cost-effective, and easy-to-use biomarker in daily clinical practice.
Introducción: Desde que se inició la pandemia por el SARS-CoV-2, se han descrito numerosos casos de síndrome de Guillain-Barré secundario a la COVID-19. Su presentación típica es la triada de ...parestesias, debilidad muscular ascendente y arreflexia, aunque hay diversas variantes regionales como la diplejía facial.
Presentación del caso: Mujer de 35 años que, dos semanas después de un contacto estrecho con un caso confirmado de COVID-19, ingresa por miopericarditis probablemente viral, con estudio de autoinmunidad negativo, múltiples serologías virales negativas y positividad para IgG anti-SARS-CoV-2 con PCR negativa. Una semana tras el alta presenta paresia de ambos nervios faciales sin otras alteraciones neurológicas. Se realiza TAC craneal sin hallazgos y EMG que evidencia afectación bilateral de los nervios faciales. La paciente rechaza realización de punción lumbar
Discusión: La diplejía facial puede ocurrir en el contexto de diversas patologías, como tumores meníngeos o troncoencefálicos, agentes infecciosos, síndrome de Guillain-Barré, patologías autoinmunes, traumatismos, causas metabólicas o causas congénitas. En el caso descrito tras descartar mediante pruebas de imagen y analíticamente el resto de etiologías, y dada la presentación clínica, permanece como causa más probable el síndrome de Guillain-Barré, posiblemente secundario a infección por SARS-CoV-2 dada la positividad de IgG anti-SARS-CoV-2 tras un contacto con un caso confirmado.
Conclusión: Este caso apoya la hipótesis de que la COVID-19 puede desencadenar el síndrome de Guillain-Barré, específicamente en forma de diplejía facial, una variante atípica que se debe conocer para su identificación y manejo precoz como parte de este síndrome.
Since December 2019, the COVID-19 pandemic has changed the concept of medicine. This work aims to analyze the use of antibiotics in patients admitted to the hospital due to SARS-CoV-2 infection. This ...work analyzes the use and effectiveness of antibiotics in hospitalized patients with COVID-19 based on data from the SEMI-COVID-19 registry, an initiative to generate knowledge about this disease using data from electronic medical records. Our primary endpoint was all-cause in-hospital mortality according to antibiotic use. The secondary endpoint was the effect of macrolides on mortality. Of 13,932 patients, antibiotics were used in 12,238. The overall death rate was 20.7% and higher among those taking antibiotics (87.8%). Higher mortality was observed with use of all antibiotics (OR 1.40, 95% CI 1.21-1.62; p < .001) except macrolides, which had a higher survival rate (OR 0.70, 95% CI 0.64-0.76; p < .001). The decision to start antibiotics was influenced by presence of increased inflammatory markers and any kind of infiltrate on an x-ray. Patients receiving antibiotics required respiratory support and were transferred to intensive care units more often. Bacterial co-infection was uncommon among COVID-19 patients, yet use of antibiotics was high. There is insufficient evidence to support widespread use of empiric antibiotics in these patients. Most may not require empiric treatment and if they do, there is promising evidence regarding azithromycin as a potential COVID-19 treatment.
