Sexting in times of confinement. An analysis of sending online sexual content before and during COVID-19 pandemic amongst university students: An International Journal of Pure Communication Inquiry

Sexting is a common practice among young adults that consists of sending material with sexual content to other people. During the COVID-19 pandemic containment situation, the main means of exploring sexuality have been through digital devices. Therefore, the purpose of this paper is to analyze the practice of sexting before and during confinement due to COVID-19 amongst Spanish university students. A longitudinal design was adopted from the application of an online survey based on three standardized and internationally used instruments on a sample of university students (n = 499) before and during confinement. The results indicated that the practice of sexting was slightly higher during confinement. At the same time, the use of dating applications was a conditioning factor in sexting. Furthermore, it was noted that sexting had a significant influence on college students' levels of self-control, depression, anxiety, and stress during confinement. Finally, the main conclusions of this study are discussed where the situation of confinement has had an impact on the lives of students and their habits of digital consumption and expression of sexuality.

Cardiac complications in a geriatric population hospitalized with COVID-19: The OCTA-COVID cohort.

PURPOSE: The geriatric population is especially vulnerable to coronavirus disease (COVID-19) and its potential complications. We sought to analyze the incidence of cardiological complications in an elderly population hospitalized for COVID-19. METHODS: A prospective observational longitudinal that included patients ≥75 years of age with diagnosis of COVID-19 admitted to the Geriatric Department from March to May 2020. Epidemiological, geriatric, clinical and laboratory test variables were collected. Cardiovascular events, including de novo atrial fibrillation (AF), acute coronary syndrome (ACS), congestive heart failure (CHF), pulmonary embolism and in-hospital death, were documented. A follow-up was carried out at 12 months through a telephone interview as well as using electronic medical records, collecting cardiac events and mortality. RESULTS: 305 patients were included; 190 (62.3%) were female, with median age of 87 years (interquartile range (82-91)). More than half of the patients had a history of cardiac disease, with AF being the most common and affecting 85 (27.9%) patients. During hospitalization, 112 (36.7%) patients died. Eighty-nine (29.2%) patients presented cardiac complications. Acute heart failure was the most prevalent (46; 15.1%), followed by new-onset AF (20; 6.5%), pulmonary embolism (17; 5.6%), and ACS (5; 1.6%). Patients with cardiac complications had a longer hospital stay (p<0.001). During follow-up, 29 (15.1%) died, and 40 (20.8%) patients had a cardiovascular event being CHF the most prevalent complication (16.7%). CONCLUSION: The incidence of cardiovascular complications in geriatric patients is high and is associated with a longer hospital stay. CHF was the most frequent event, followed by AF.

Designing Materials for Emergency Remote Language Teaching Contexts: A Qualitative Study of Pre-Service Teachers' Experiences

Emergency Remote Language Teaching is a new term coined after the concept of Emergency Remote Teaching (Hodges, et al., 2020), which emphasizes that teaching that is being done during emergencies and crises, as the pandemic caused by COVID-19, is neither distance nor online teaching properly. This paper explores the attitudes and perceptions of pre-service bilingual primary teachers at the University of Córdoba (Spain) regarding the design of socially and culturally responsive learning materials in a real Emergency Remote Language Teaching context. Due to the nature of this exploratory research, this study was designed to perform a qualitative analysis. To analyze the data, the grounded-theory scheme was followed to establish different categories and topics, then content analysis was applied, and finally, a manual SWOT analysis was created. Participants showed positive attitudes towards the design of materials for Emergency Remote Language Teaching, emphasizing the feeling of real teachers, the design of resources with a meaningful purpose, and the importance of 'thinking outside the box.' They also found challenges derived from the new, complex situation, and the lack of experience designing materials for distance teaching. Recommendations are proposed for teacher training and materials design in Emergency Remote Language Teaching contexts.

Plitidepsin has a positive therapeutic index in adult patients with COVID-19 requiring hospitalization. (preprint)

Plitidepsin is a marine-derived cyclic-peptide that inhibits SARS-CoV-2 replication at low nanomolar concentrations by the targeting of host protein eEF1A (eukaryotic translation-elongation-factor-1A). We evaluated a model of intervention with plitidepsin in hospitalized COVID-19 adult patients where three doses were assessed (1.5, 2 and 2.5 mg/day for 3 days, as a 90-minute intravenous infusion) in 45 patients (15 per dose-cohort). Treatment was well tolerated, with only two Grade 3 treatment-related adverse events observed (hypersensitivity and diarrhea). The discharge rates by Days 8 and 15 were 56.8% and 81.8%, respectively, with data sustaining dose-effect. A mean 4.2 log10 viral load reduction was attained by Day 15. Improvement in inflammation markers was also noted in a seemingly dose-dependent manner. These results suggest that plitidepsin impacts the outcome of patients with COVID-19.

Two Interventions to Provide Support to Long-Term Care Facilities During the Covid-19 Pandemic (preprint)

BACKGROUND The aim of this article is to describe two interventions carried out during the first wave of the COVID19 pandemic to support healthcare personnel at 60 nursing homes, located within the coverage area of a 613-bed university tertiary care hospital. METHODS In the first intervention, a geriatrician provided telephone support, including help with the clinical management of residents, the administration of intravenous and/or hospital-based treatments, provision of oxygen therapy at the facility, blood and diagnostic tests, and the coordination of disinfection by the Military Emergency Unit. In the second intervention, the multidisciplinary care team also performed on-site visits to the nursing homes. RESULTS In the first telephone support intervention 4,553 cases were evaluated. Of these cases, 645 residents (14.2%) were given on-site intravenous therapy; 419 cases (9%) were prescribed oxygen therapy, and 573 nasopharyngeal exudate samples were tested (RT-PCR). In the second intervention, 4,965 residents were assessed on-site. Of these, intravenous treatment was prescribed in 316 patients (6.3% of cases) and oxygen therapy in 634 (12.7%). A total of 2.458 RT-PCR tests were performed on residents and workers. There was a decrease in the mortality rate ten days after the implementation of the second intervention. CONCLUSIONS Geriatrician-directed telephone support is a highly efficient and essential approach to coordinate long-distance healthcare delivery at nursing homes, but it doesn't seem to reduce mortality. Interventions, including multidisciplinary/Geriatrics visits in nursing homes during pandemics are needed to study if mortality rates can be reduced.

A multiplex antigen microarray for simultaneous IgG and IgM detection against SARS‐CoV‐2 reveals higher seroprevalence than reported

The surge of SARS‐CoV‐2 has challenged health systems worldwide and efficient tests to detect viral particles, as well as antibodies generated against them, are needed. Specificity, sensitivity, promptness or scalability are the main parameters to estimate the final performance, but rarely all of them match in a single test. We have developed SCOVAM, a protein microarray with several viral antigens (spike, nucleocapsid, main protease Nsp5) as capturing probes in a fluorescence immunoassay for COVID‐19 serological testing. SCOVAM depicts IgG and IgM antibody responses against each of these proteins of 22 individuals in a single microscope slide. It detects specific IgM (0.094 μg ml‐1) and IgG (~0.017 μg ml‐1) and is scalable and cost‐effective. We validated SCOVAM by comparing with a widely used chemiluminescent commercial serological test (n = 742). SCOVAM showed twice the sensitivity and allowed following seroconversion in a single assay. By analysing the prevalence 4 months later in a subset of 76 positive sera, we still detected 93.42% of positives, almost doubling the detection of the commercial assay. The higher sensitivity of SCOVAM is especially relevant to screen sera for convalescent plasma‐based treatments, high‐throughput antibody response monitoring after vaccination or evaluation of vaccine efficiency.

OBJETIVO: En tiempos de pandemia, la gestión de casos y el rastreo de contactos pueden ser elementos diferenciales para el control de la propagación de la misma. El objetivo de esta revisión fue evaluar las herramientas digitales empleadas para el rastreo de contactos de personas contagiadas de SARS-CoV-2. MÉTODOS: Se realizó una revisión sistemática exploratoria en las bases de datos electrónicas Pubmed, Scopus y Web of Science el día 29 de mayo de 2020 a través de los descriptores: coronavirus, digital surveillance y contact tracing. Se seleccionaron finalmente un total de 11 estudios. RESULTADOS: Los resultados mostraron cómo algunos países están implantando herramientas digitales para el rastreo de contactos a través de aplicaciones para móviles, las cuales permiten compartir datos de los usuarios a través del GPS y/o Bluetooth del dispositivo. Los términos sobre la privacidad y confidencialidad de los datos de la población están, en algunos casos, en entredicho. CONCLUSIONES: El uso de herramientas de vigilancia digital para el rastreo de contactos de personas contagiadas de una enfermedad infecciosa, como la provocada por el SARS-CoV-2, puede ser capital para reducir el número de personas infectadas y reducir la propagación del virus BACKGROUND: In times of pandemic, case management and tracking people with contact can be differential elements for controlling the spread. The objective of this review was to evaluate the digital tools used to track contacts of people infected with SARS-CoV-2. METHODS: A systematic exploratory review was conducted in the electronic databases Pubmed, Scopus and Web of Science on May 29, 2020 through the descriptors: coronavirus, digital surveillance and contact tracing. A total of 11 studies were finally selected. RESULTS: The results showed that some countries are implementing digital tools for contact tracking through mobile apps that allow user data to be shared via the device's GPS and/or Bluetooth. The terms on the privacy and confidentiality of the population data are, in some cases, questionable. CONCLUSIONS: The use of digital surveillance tools to track contacts of people infected with an infectious disease, such as SARS-CoV-2, can be key to reducing the number of people infected and reducing the spread of the virus

Anakinra After Corticosteroid and/or Tocilizumab Treatment in Patients with Severe COVID-19 Pneumonia and Moderate Hyperinflammation. A Retrospective Cohort Study. (preprint)

Introduction: Little evidence appears to exists for the use of anakinra, a recombinant interleukin-1 receptor antagonist, after non-response to treatment with corticosteroids alone or combined with tocilizumab in patients with severe COVID-19 pneumonia and moderate hyperinflammatory state. Patients and Methods: A retrospective observational cohort study was carried out involving 143 patients with severe COVID-19 pneumonia and moderate hyperinflammation. They received standard therapy along with pulses of methylprednisolone (group 1) or methylprednisolone plus tocilizumab (group 2), with the possibility of receiving anakinra (group 3) according to protocol. The aim of this study was to assess the role of anakinra in the clinical course (death, admission to the intensive care ward) during the first 60 days after the first corticosteroid pulse. Clinical, laboratory, and imaging characteristics as well as infectious complications were also analyzed.Results: 74 patients (51.7%) in group 1, 59 (41.3%) patients in group 2, and 10 patients (7%) in group 3 were included. 8 patients (10.8%) in group 1 died, 6 (10.2%) in group 2, and 0 (0%) in group 3. After adjustment for age and clinical severity indices, treatment with anakinra was associated with a reduced risk of mortality (adjusted hazard ratio 0.518, 95% CI 0.265-0.910; p=0.0437). Patients in group 3 had a lower mean CD4 count after 3 days of treatment. No patients in this group presented infectious complications.Conclusions: In patients with moderate hyperinflammatory state associated with severe COVID-19 pneumonia, treatment with anakinra after non-response to corticosteroids or corticosteroids plus tocilizumab therapy may be an option for the management of these patients, and may improve their prognosis.

Características, evolución clínica y factores asociados a la mortalidad en UCI de los pacientes críticos infectados por SARS-CoV-2 en España: estudio prospectivo, de cohorte y multi-céntrico

Resumen Antecedentes: No se ha reportado plenamente la evolución clínica de los pacientes críticos de COVID-19 durante su ingreso en la unidad de cuidados intensivos (UCI), incluyendo las complicaciones médicas e infecciosas y terapias de soporte, así como su asociación con la mortalidad en ICU. Objetivo: El objetivo de este estudio es describir las características clínicas y la evolución de los pacientes ingresados en UCI por COVID-19, y determinar los factores de riesgo de la mortalidad en UCI de dichos pacientes. Métodos: Estudio prospectivo, multi-céntrico y de cohorte, que incluyó a los pacientes críticos de COVID-19 ingresados en 30 UCIs de España y Andorra. Se incluyó a los pacientes consecutivos de 12 de Marzo a 26 de Mayo de 2020 si habían fallecido o habían recibido el alta de la UCI durante el periodo de estudio. Se reportaron los datos demográficos, síntomas, signos vitales, marcadores de laboratorio, terapias de soporte, terapias farmacológicas, y complicaciones médicas e infecciosas, realizándose una comparación entre los pacientes fallecidos y los pacientes dados de alta. Resultados: Se incluyó a un total de 663 pacientes. La mortalidad general en UCI fue del 31% (203 pacientes). Al ingreso en UCI los no supervivientes eran más hipoxémicos [SpO2 sin mascarilla de no reinhalación, de 90 (RIC 83 - 93) vs 91 (RIC 87 - 94);p<0,001] y con mayor puntuación en la escala SOFA - Evaluación de daño orgánico secuencial - [SOFA, 7 (RIC 5 - 9) vs 4 (RIC 3 - 7);p<0,001]. Las complicaciones fueron más frecuentes en los no supervivientes: síndrome de distrés respiratorio agudo (SDRA) (95% vs 89%;p=0,009), insuficiencia renal aguda (IRA) (58% vs 24%;p<10-16), shock (42% vs 14%;p<10-13), y arritmias (24% vs 11%;p<10-4). Las súper-infecciones respiratorias, infecciones del torrente sanguíneo y los shock sépticos fueron más frecuentes en los no supervivientes (33% vs 25%;p=0,03, 33% vs 23%;p=0,01 y 15% vs 3%, p=10-7), respectivamente. El modelo de regresión multivariable reflejó que la edad estaba asociada a la mortalidad, y que cada año incrementaba el riesgo de muerte en un 1% (95%IC: 1 - 10, p=0,014). Cada incremento de 5 puntos en la escala APACHE II predijo de manera independiente la mortalidad [OR: 1,508 (1,081, 2,104), p= 0,015]. Los pacientes con IRA [OR: 2,468 (1,628, 3,741), p<10-4)], paro cardiaco [OR: 11,099 (3,389, 36,353), p= 0,0001], y shock séptico [OR: 3,224 (1,486, 6,994), p= 0,002] tuvieron un riesgo de muerte incrementado. Conclusiones: Los pacientes mayores de COVID-19 con puntuaciones APACHE II más altas al ingreso, que desarrollaron IRA en grados II o III y/o shock séptico durante la estancia en UCI tuvieron un riesgo de muerte incrementado. La mortalidad en UCI fue del 31%. Background: The clinical course of COVID-19 critically ill patients, during their admission in the intensive care unit (UCI), including medical and infectious complications and support therapies, as well as their association with in-ICU mortality has not been fully reported. Objective: This study aimed to describe clinical characteristics and clinical course of ICU COVID-19 patients, and to determine risk factors for ICU mortality of COVID-19 patients. Methods: Prospective, multicentre, cohort study that enrolled critically ill COVID-19 patients admitted into 30 ICUs from Spain and Andorra. Consecutive patients from March 12th to May 26th, 2020 were enrolled if they had died or were discharged from ICU during the study period. Demographics, symptoms, vital signs, laboratory markers, supportive therapies, pharmacological treatments, medical and infectious complications were reported and compared between deceased and discharged patients. Results: A total of 663 patients were included. Overall ICU mortality was 31% (203 patients). At ICU admission non-survivors were more hypoxemic [SpO2 with non-rebreather mask, 90 (IQR 83 to 93) vs 91 (IQR 87 to 94);p<0.001] and with higher sequential organ failure assessment score [SOFA, 7 (IQR 5 to 9) s 4 (IQR 3 to 7);p<0.001]. Complicatio s were more frequent in non-survivors: acute respiratory distress syndrome (ARDS) (95% vs 89%;p=0.009), acute kidney injury (AKI) (58% vs 24%;p<10-16), shock (42% vs 14%;p<10-13), and arrhythmias (24% vs 11%;p<10-4). Respiratory super-infection, bloodstream infection and septic shock were higher in non-survivors (33% vs 25%;p=0.03, 33% vs 23%;p=0.01 and 15% vs 3%, p=10-7), respectively. The multivariable regression model showed that age was associated with mortality, with every year increasing risk-of-death by 1% (95%CI: 1 to 10, p=0.014). Each 5-point increase in APACHE II independently predicted mortality [OR: 1.508 (1.081, 2.104), p= 0.015]. Patients with AKI [OR: 2.468 (1.628, 3.741), p<10-4)], cardiac arrest [OR: 11.099 (3.389, 36.353), p= 0.0001], and septic shock [OR: 3.224 (1.486, 6.994), p= 0.002] had an increased risk-of-death. Conclusions: Older COVID-19 patients with higher APACHE II scores on admission, those who developed AKI grades II or III and/or septic shock during ICU stay had an increased risk-of-death. ICU mortality was 31%.

Performance and health economic evaluation of the Mount Sinai COVID-19 serological assay identifies modification of thresholding as necessary to maximise specificity of the assay (preprint)

We evaluated the FDA approved SARS-CoV-2 immunoassay (developed at Mount Sinai, by Krammer and colleagues) for the identification of COVID-19 seroconversion and potential cross-reactivity of the assay in a United Kingdom (UK) National Health Service (NHS) hospital setting. In our "set up" cohort we found that the SARS-CoV-2 IgG was detectable in 100% of patients tested 14 days post positive COVID-19 nucleic acid test. Serum samples taken from pregnant women in 2018 were used as a negative control group with zero false positives. We also analysed samples from patients with non-COVID-19 viral infections, paraproteinaemia or autoantibodies and found false positive results in 6/179. Modification of the sensitivity threshold to five standard deviations from the mean of the control group eliminated all false positive result in the set up cohort. We confirmed the validity of the test with a revised threshold on an independent prospective "validation cohort" of patient samples. Taking data from both cohorts we report a sensitivity of the Mount Sinai assay of 96.6% (28/29) and specificity of 100% (299/299) using a revised threshold cut-off, at a time point at least 14 days since the diagnostic antigen test. Finally, we conducted a health economic probabilistic sensitivity analysis (PSA) on the costs of producing the tests, and the mean cost we estimate to be 13.63 pounds sterling (95%CI 9.63 - 18.40), allowing its cost effectiveness to be tested against other antibody tests. In summary, we report that the Mount Sinai IgG ELISA assay is highly sensitive test for SARS-Cov-2 infection, however modification of thresholding was required to minimise false positive results.

IMPACT OF GLUCOCORTICOID TREATMENT IN SARS-COV-2 INFECTION MORTALITY: A RETROSPECTIVE CONTROLLED COHORT STUDY (preprint)

Objective: We aim to determine the impact of steroid use in COVID-19 pneumonia in-hospital mortality. Design: We performed a single-centre retrospective cohort study. Setting: A University hospital in Madrid, Spain, during March 2020. Participants: Patients admitted with SARS-CoV-2 pneumonia. Exposures: Patients treated with steroids were compared to patients not treated with steroids. A propensity-score for steroid treatment was developed. Different steroid regimens were also compared, and adjusted with a second propensity score. Main Outcomes and Measures: To determine the role of steroids in in-hospital mortality, univariable and multivariable analyses were performed, and adjusted including the propensity score as a covariate. Survival times were compared using a log-rank test. Results: During the study period, 463 out of 848 hospitalized patients with COVID19 pneumonia fulfilled inclusion criteria. Among them, 396 (46.7%) consecutive patients were treated with steroids and 67 patients were assigned to the control cohort. Global mortality was 15.1%. Median time to steroid treatment from symptom onset was 10 days (IQR 8 to13). In-hospital mortality was lower in patients treated with steroids than in controls (13.9% [55/396] versus 23.9% [16/67], OR 0.51 [0.27 to 0.96], p= 0.044). Steroid treatment reduced mortality by 41.8% relative to no steroid treatment (RRR 0,42 [0.048 to 0.65). Initial treatment with 1 mg/kg/day of methylprednisolone (or equivalent) versus steroid pulses was not associated with in-hospital mortality (13.5% [42/310] versus 15.1% [13/86], OR 0.880 [0.449-1.726], p=0.710). Conclusions: Our results show that survival of patients with SARS-CoV2 pneumonia is higher in patients treated with glucocorticoids than in those not treated. In-hospital mortality was not different between initial regimens of 1 mg/kg/day of methylprednisolone or equivalent and glucocorticoid pulses. These results support the use of glucocorticoids in SARS-CoV2 infection.
