[Critical patients COVID-19 Has changed the management and outcomes in the ICU after 1 year of the pandemic?A multicenter, prospective, observational study]. / Pacientes críticos COVID-19 ¿Ha variado el manejo y resultados en la UCI tras 1 año de pandemia? Estudio multicéntrico, prospectivo, observacional.

OBJECTIVE: To compare the clinical characteristics, treatments, and evolution of critical patients with COVID-19 pneumonia treated in Intensive Care Units (ICU) after one year of pandemic. METHODOLOGY: Multicenter, prospective study, which included critical COVID-19 patients in 9 ICUs in northwestern Spain. The clinical characteristics, treatments, and evolution of patients admitted to the ICU during the months of March-April 2020 (period 1) were compared with patients admitted in January-February 2021 (period 2). RESULTS: 337 patients were included (98 in period 1 and 239 in period 2). In period 2, fewer patients required invasive mechanical ventilation (IMV) (65% vs 84%, p <0.001), using high-flow nasal cannulas (CNAF) more frequently (70% vs 7%, p <0.001), ventilation non-invasive mechanical (NIMV) (40% vs 14%, p <0.001), corticosteroids (100% vs 96%, p = 0.007) and prone position in both awake (42% vs 28%, p = 0.012), and intubated patients (67% vs 54%, p = 0.034). The days of IMV, ICU stay and hospital stay were lower in period 2. Mortality was similar in the two periods studied (16% vs 17%). CONCLUSIONS: After 1 year of pandemic, we observed that in patients admitted to the ICU, CNAF, NIMV, use of the prone position, and corticosteroids have been used more frequently, reducing the number of patients in IMV, and the length of stay in the ICU and hospital stay. Mortality was similar in the two study periods.

Psychological and quality of life effects of vaccination against COVID-19 in patients with systemic autoimmune diseases.

To verify the psychological and quality of life benefits of vaccination against COVID-19 in patients with systemic autoimmune diseases. In this study, levels of psychological stress, psychopathological symptoms, quality of life, and satisfaction with life were compared in patients with systemic autoimmune diseases vaccinated against COVID-19 (n = 132) versus unvaccinated patients (n = 254). To this end, we used the Perceived Stress Scale (PSS), Symptom Checklist-90-Revised (SCL-90-R), EUROQoL-5Q health questionnaire, and Satisfaction with Life Scale (SWLS), respectively. Statistically significant differences were found with better scores in the vaccinated group in the following quality of life dimensions: mobility (p ≤ 0.010), domestic activities (p ≤ 0.004), pain/discomfort (p ≤ 0.001), and anxiety/depression (p≤ 0.005). The scores were also significantly higher in the vaccinated group for the total values of quality of life (p ≤ 0.001), health status self-assessment on the EUROQoL-5Q (p ≤ 0.043), and satisfaction with life (p ≤ 0.015). In addition, the unvaccinated group presented higher scores with clinically pathological levels in depression and psychoticism for somatizations (p ≤ 0.006), depression (p ≤ 0.015), anxiety (p ≤ 0.003), and phobic anxiety (p ≤ 0.001). Finally, participants vaccinated with the complete regimen showed better levels of psychological well-being than those who were not vaccinated or those that had not completed the vaccination regimen. Our results reflect and confirm the positive effects reported elsewhere of the COVID-19 vaccine in autoimmune patients with systemic diseases, both in terms of quality and satisfaction with life as well as psychopathological symptoms and perceived stress. These benefits increased as the patients completed their vaccination schedule.

Deep Convolutional Approaches for the Analysis of COVID-19 Using Chest X-Ray Images From Portable Devices.

The recent human coronavirus disease (COVID-19) is a respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Given the effects of COVID-19 in pulmonary tissues, chest radiography imaging plays an important role in the screening, early detection, and monitoring of the suspected individuals. Hence, as the pandemic of COVID-19 progresses, there will be a greater reliance on the use of portable equipment for the acquisition of chest X-ray images due to its accessibility, widespread availability, and benefits regarding to infection control issues, minimizing the risk of cross-contamination. This work presents novel fully automatic approaches specifically tailored for the classification of chest X-ray images acquired by portable equipment into 3 different clinical categories: normal, pathological, and COVID-19. For this purpose, 3 complementary deep learning approaches based on a densely convolutional network architecture are herein presented. The joint response of all the approaches allows to enhance the differentiation between patients infected with COVID-19, patients with other diseases that manifest characteristics similar to COVID-19 and normal cases. The proposed approaches were validated over a dataset specifically retrieved for this research. Despite the poor quality of the chest X-ray images that is inherent to the nature of the portable equipment, the proposed approaches provided global accuracy values of 79.62%, 90.27% and 79.86%, respectively, allowing a reliable analysis of portable radiographs to facilitate the clinical decision-making process.

Endonuclease-based genotyping of the RBM as a method to track the emergence or evolution of SARS-CoV-2 variants.

Since the beginning of the COVID-19 pandemics, variants have emerged. Some of them display increased transmissibility and/or resistance to immune response. Most of the mutations involved in the functional adaptation are found in the receptor-binding motif (RBM), close to the interface with the receptor ACE2. We thus developed a fast molecular assay to detect mutations in the RBM coding sequence. After amplification, the amplicon is heat-denatured and hybridized with an amplicon of reference. The presence of a mutation can be detected using a mismatch-specific endonuclease and the cleavage pattern is analyzed by capillary electrophoresis. The method was validated on RNA of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants produced in vitro before being implemented for clinical samples. The assay showed 97.8% sensitivity and 97.8% specificity. The procedure can be set up for high-throughput identification of the presence of mutations and serve as a first-line screening to select the samples for full genome sequencing.

Sars-Cov-2 Infection in Patients on Long-Term Treatment with Macrolides in Spain: A National Cross-Sectional Study.

The aim of this study was to know the prevalence and severity of COVID-19 in patients treated with long-term macrolides and to describe the factors associated with worse outcomes. A cross-sectional study was conducted in Primary Care setting. Patients with macrolides dispensed continuously from 1 October 2019 to 31 March 2020, were considered. Main outcome: diagnosis of coronavirus disease-19 (COVID-19). Secondary outcomes: symptoms, severity, characteristics of patients, comorbidities, concomitant treatments. A total of 3057 patients met the inclusion criteria. Median age: 73 (64-81) years; 55% were men; 62% smokers/ex-smokers; 56% obese/overweight. Overall, 95% of patients had chronic respiratory diseases and four comorbidities as a median. Prevalence of COVID-19: 4.8%. This was in accordance with official data during the first wave of the pandemic. The most common symptoms were respiratory: shortness of breath, cough, and pneumonia. Additionally, 53% percent of patients had mild/moderate symptoms, 28% required hospital admission, and 19% died with COVID-19. The percentage of patients hospitalized and deaths were 2.6 and 5.8 times higher, respectively, in the COVID-19 group (p < 0.001). There was no evidence of a beneficial effect of long-term courses of macrolides in preventing SARS-CoV-2 infection or the progression to worse outcomes in old patients with underlying chronic respiratory diseases and a high burden of comorbidity.

Effect of COVID-19 confinement on the mental status of patients with systemic lupus erythematosus.

BACKGROUND AND OBJECTIVE: Patients with systemic lupus erythematosus (SLE) are more vulnerable to higher levels of stress and psychopathological symptoms than the general healthy population. Therefore, the COVID-19 outbreak could alter their psychological state. The objective was to analyze the psychological impact of the pandemic and confinement on stress levels and psychopathological symptoms in patients with SLE. PATIENTS AND METHOD: In this cross-sectional study, stress levels were compared with the Perceived Stress Scale, the Stress Vulnerability Inventory and psychopathological symptoms of the SCL-90-R Symptom Inventory in patients with SLE during the period of confinement (group 1; n = 276) in comparison to patients with SLE evaluated in a period before the pandemic (group 2; n = 152). RESULTS: The comparison between both groups showed there were statistically significant differences in vulnerability to stress (p < 0.0001), depression (p ≤ 0.05), anxiety (p ≤ 0.05), phobic anxiety (p < 0.0001), interpersonal sensitivity (p ≤ 0.043), and psychoticism (p ≤ 0.023). In these variables, the group of patients with lupus in confinement obtained higher scores. CONCLUSIONS: The confinement and threat of the COVID-19 outbreak had important repercussions on the psychological state of patients with SLE with high levels of stress, anxiety, and depression. These findings show their vulnerability to a public health alert and indicate the need to carry out a psychological approach to these patients while the state of health emergency lasts as well as to possible outbreaks of the virus.

ANTECEDENTES Y OBJETIVO: Las pacientes con lupus eritematoso sistémico (LES) son más vulnerables a presentar mayores niveles de estrés y síntomas psicopatológicos que la población general sana, por lo que el brote de la COVID-19 podría alterar su estado psicológico. El objetivo fue analizar el impacto psicológico de la pandemia y del confinamiento sobre los niveles de estrés y sintomatología psicopatológica en pacientes con LES. PACIENTES Y MÉTODO: En este estudio transversal se compararon niveles de estrés mediante la Escala de Estrés Percibido y el Inventario de Vulnerabilidad al Estrés, y síntomas psicopatológicos mediante el Inventario de síntomas SCL-90-R, en pacientes con LES durante el período de confinamiento (grupo 1; n = 276) con respecto a pacientes con LES evaluadas en un período anterior a la pandemia (grupo 2; n = 152). RESULTADOS: La comparación entre ambos grupos mostró que existían diferencias estadísticamente significativas en vulnerabilidad al estrés (p < 0,0001), depresión (p ≤ 0,05), ansiedad (p ≤ 0,05), ansiedad fóbica (p < 0,0001), sensibilidad interpersonal (p ≤ 0,043), y psicoticismo (p ≤ 0,023). En estas variables el grupo de pacientes con lupus en confinamiento obtuvo puntuaciones superiores. CONCLUSIONES: El confinamiento y la amenaza del brote por COVID-19 ha tenido importantes repercusiones en el estado psicológico de las pacientes con LES, mostrando altos niveles de estrés, ansiedad y depresión. Estos hallazgos muestran su vulnerabilidad ante una alerta de salud pública, y señala la necesidad de realizar un abordaje psicológico de estas pacientes mientras dure el estado de emergencia sanitaria, así como ante posibles rebrotes del virus.

Educación a distancia en tiempos de COVID-19: Análisis desde la perspectiva de los estudiantes universitarios

Este artículo sitúa el foco de interés en los estudiantes de las universidades presenciales y en los modelos de enseñanza a distancia (ED) implementados durante el periodo de confinamiento causado por la crisis del COVID-19. Los objetivos son analizar la incidencia del contexto personal y familiar en la equidad digital, identificar el modelo de enseñanza recibido, y conocer su valoración y percepción sobre este modelo. La investigación obedece a un estudio mixto de alcance descriptivo en el que se combinan métodos cualitativos y cuantitativos. En primer lugar, se realizó un cuestionario a estudiantes de la Universidad de Extremadura (UEx) (n= 548) y a posteriori se efectuaron entrevistas online a miembros del equipo de gobierno de la universidad. Los resultados indican que los estudiantes procedentes de familias con un nivel formativo bajo tienen menos oportunidades de uso de tecnologías digitales. Las clases virtuales que han recibido han consistido esencialmente en presentaciones subidas al campus virtual con interacciones asíncronas. La valoración negativa que hacen de la enseñanza a distancia se explica por la inversa relación percibida entre dedicación al estudio y rendimiento académico y por falta de adaptación de los docentes a las circunstancias personales y académicas de los estudiantes. En conclusión, se determina que la universidad debe transitar hacia modelos más colaborativos y centrados en el estudiante.Alternate abstract:This paper focuses on the students of traditional face-to-face universities and on the implemented distance learning models during the lockdown period caused by the COVID-19' crisis. We aim here to analyze the impact of the personal and family context on digital equity, to identify the teaching model received, and to know their assessment and perception of this model. The research is a mixed study of descriptive scope in which qualitative and quantitative methods are combined. Firstly, a survey was carried out with students from the University of Extremadura (n=548) and, then, online interviews were conducted to members of the university governance. The results indicate that students from families with a low educational level have fewer opportunities to use digital technologies. Virtual lessons, which students have received, have essentially been based on presentations uploaded to the virtual campus with asynchronous interactions. The negative assessment of distance learning is explained by the apparent reverse relationship between time spent studying and academic performance and by the lack of teachers' adaptation to students' personal and academic circumstances. In conclusion, the university must move towards more collaborative and student-centered models.

COVID-19 in lung transplant recipients: A multicenter study.

This study describes the clinical presentation, treatment, and outcomes of SARS-CoV-2 infection in lung transplant recipients (LTRs). This is a multicenter, retrospective study of all adult LTRs with confirmed SARS-CoV-2 infection from March 4 until April 28, 2020 in six Spanish reference hospitals for lung transplantation. Clinical and radiological data, treatment characteristics, and outcomes were reviewed. Forty-four cases were identified in that period. The median time from transplantation was 4.2 (interquartile range: 1.11-7.3) years. Chest radiography showed acute parenchymal abnormalities in 32 (73%) cases. Hydroxychloroquine was prescribed in 41 (93%), lopinavir/ritonavir (LPV/r) in 14 (32%), and tocilizumab in 19 (43%) patients. There was a strong interaction between tacrolimus and LPV/r in all cases. Thirty-seven (84%) patients required some degree of respiratory support and/or oxygen therapy, and 13 (30%) were admitted to intermediate or intensive critical care units. Seventeen (39%) patients had died and 20 (45%) had been discharged at the time of the last follow-up. Deceased patients had a worse respiratory status and chest X-ray on admission and presented with higher D-dimer, interleukin-6, and lactate dehydrogenase levels. In this multicenter LTR cohort, SARS-CoV-2 presented with high mortality. Additionally, the severity of disease on presentation predicted subsequent mortality.
