HCoV-NL63 and HCoV-HKU1 seroprevalence and its relationship with the clinical features of COVID-19 patients from Villavicencio, Colombia / Seroprevalencia de HCoV-NL63 y HCoV-HKU1 y su relación con las características clínicas de pacientes con COVID-19 de Villavicencio, Colombia

ABSTRACT Introduction. Due to the cross-reactivity between SARS-CoV-2 and common human coronaviruses, previous infections with these viruses could contribute to serological or cellular cross-protection against severe COVID-19. However, protective immunity may not develop, or pre-existing immunity could increase COVID-19 severity. Objective. To determine the seroprevalence of IgG antibodies against HCoV-NL63 and HCoV-HKU1 and correlate previous exposure with COVID-19 signs in patients from Villavicencio. Materials and methods. A cross-sectional retrospective study was conducted. ELISA technique was used to search for IgG antibodies against HCoV-NL3 and HCoV-HKU1 in patients with positive RT-qPCR results for SARS-CoV-2. Patients were grouped according to COVID-19 clinical characteristics in four groups: group 1: asymptomatic (n = 23); group 2: hospitalized (n = 24); group 3: intensive care units (n = 24), and group 4: dead (n = 22). Results. The overall seroprevalence of IgG antibodies against HCoV was 74.2% (n = 69; 95% CI: 65.3-83.1), with 66.7% of HCoV-NL63 (n = 62; 95% CI: 57,1-76,2), and 25.8% of HCoV-HKU1 (n = 24; 95% CI: 16,9-34,7). Based on crosstab analysis, prior exposure to HCoV-NL63 was associated with protection against severe COVID-19 (p = 0.042; adjusted OR = 0.159; 95% CI: 0.027-0.938), and previous coinfection of HCoV-NL63 and HCoV-HKU1 was considered a positive association to severe COVID-19 (p = 0.048; adjusted OR = 16.704; 95% CI: 1.020 - 273.670). Conclusion. To our knowledge, this is the first study addressing seroprevalence of HCoV IgG antibodies in Colombia and Latin America. Previous exposure to HCoV-NL63 could protect against severe COVID-19, whereas patients with underlying HCoV-NL63 and HCoV-HKU1 coinfection could be hospitalized with severe signs of COVID-19.

RESUMEN Introducción. Debido a la reactividad cruzada entre SARS-CoV-2 y los coronavirus humanos comunes, las infecciones previas con estos virus podrían contribuir a la protección cruzada serológica o celular contra la COVID-19 grave. Sin embargo, la inmunidad protectora puede no desarrollarse o la inmunidad preexistente podría generar COVID-19 grave. Objetivo. Determinar la seroprevalencia de anticuerpos IgG frente a HCoV-NL63 y HCoV-HKU1, y correlacionar su previa exposición con los signos de COVID-19 en pacientes de Villavicencio. Materiales y métodos. Se realizó un estudio retrospectivo observacional analítico y transversal. Se utilizó la técnica ELISA para buscar anticuerpos IgG contra HCoV-NL3 y HCoV-HKU1 en pacientes con resultado positivo de RT-qPCR para SARS-CoV-2. Los pacientes se agruparon según los signos de COVID-19 en cuatro grupos: grupo 1: asintomáticos (n = 23); grupo 2: hospitalizados (n = 24); grupo 3: unidad de cuidados intensivos (n = 24), y grupo 4: fallecidos (n = 22). Resultados. La seroprevalencia general de IgG anti-HCoV fue de 74.2 % (n = 69; IC95%: 65,3-83,1), con 66,7 % de HCoV-NL63 (n = 62; IC95%: 57,1-76,2) y 25,8 % de HCoV-HKU1 (n = 24; [IC95%:16,9-34,7). Según el análisis de las tablas de contingencia, la exposición previa a HCoV-NL63 se asoció con protección de una COVID-19 grave (p = 0,042; OR ajustado = 0,159; IC95%: 0,027-0,938) y la previa coinfección de HCoV-NL63 y HCoV-HKU1 se asoció con padecimiento de signos clínicos graves por COVID-19 (p = 0,048; OR ajustado = 16,704; IC95%: 1,020- 73,670). Conclusión. Según la literatura revisada hasta la fecha, este es el primer estudio sobre la seroprevalencia de anticuerpos IgG de HCoV en Colombia y Latinoamérica. La exposición previa a HCoV-NL63 podría proteger contra la COVID-19 grave, mientras que los pacientes con coinfección subyacente de HCoV-NL63 y HCoV-HKU1 podrían resultar hospitalizados con signos graves de COVID-19.

Characteristics of endemic human Coronavirus infections during times of COVID-19 pandemic / Características de las infecciones causadas por Corona virus humanos endémicos durante la pandemia COVID-19

Abstract Introduction : After the implementation of mitigation strategies during the COVID-19 pandemic, the incidence of respiratory viruses, including human coronaviruses (HCoV), experienced a significant decrease. The aim of this study is to characterize the epidemiology and clinical aspects of HCoV infections in ambulatory adults during COVID-19 pandemic times. Methods : descriptive, prospective, longitudinal study performed in a private hospital in La Plata, Buenos Aires, Argentina between November 2020 and October 2022; 458 outpatient adults with upper respiratory tract infections (URTI) were studied undergoing clinical and microbiological follow-up. Results : 44 (9.6%) subjects were positive by multiplex PCR for HCoV. 14 of them for 229E (31.8%), 13 for OC43 (29.5%), 11 for HKU-1 (25.1%) and 6 for NL63 (13.6%). A repeated PCR was positive for the same HCoV in 19 (57%) of 33 patients on day 3-5. No hospitalizations or deaths were reported. Discussion : Endemic HCoV caused a significant pro portion of URTI among outpatient adults during COVID- 19-related restrictions times. An alternating pattern of circulation between alfa-HCoV and beta-HCoV was observed.

Primer aislamiento y caracterización de la cepa prototipo del virus SARS-CoV-2 a inicios de la pandemia de la COVID-19 en el Perú

Introducción: Actualmente los contagios por el virus del SARS-CoV-2 supera los 600 millones de casos en el mundo. Objetivo: Aislar y caracterizar el virus SARS-CoV-2 causante de la COVID-19 a inicios de la pandemia en el Perú. Materiales y métodos: Se realizó el aislamiento viral a partir de 20 muestras de hisopado nasal y faríngeo positivas a SARS-CoV-2 por RT-PCR. El aislamiento se realizó en las líneas celulares Vero ATCC CCL-81 y Vero E6, evaluando el efecto citopático, la presencia del virus por RT-PCR, inmunofluorescencia indirecta (IFI) y posterior identificación por secuenciación genómica. Posteriormente, uno de los aislamientos de mayor circulación fue seleccionado y denominado cepa prototipo (PE/B.1.1/28549/2020), realizándose 10 pasajes sucesivos en células Vero ATCC CCL-81 para evaluar la dinámica de mutaciones. Resultados: Se observaron 11 aislamientos de virus por efecto citopático confirmándose por RT-PCR e IFI, de los cuales 6 fueron secuenciados identificándose los linajes B.1, B.1.1, B.1.1.1 y B.1.205, según el comité Pango de los genomas. La cepa prototipo corresponde a la variante B.1.1 y el análisis de las secuencias de los pasajes sucesivos mostró mutaciones a nivel de la proteína de la espiga (S) del virus, sin variación en la identidad del linaje. Conclusiones: Se aislaron 4 linajes en la línea celular Vero ATCC CCL-81. Los subcultivos en la misma línea celular muestran mutaciones en la proteína de la espiga, lo que indica mayor adaptabilidad a la célula hospedera y variación de la patogenicidad in vitro, comportamiento que le permite tener más éxito de supervivencia.

Introduction: Currently, infections caused by the SARS-CoV-2 virus exceed 600 million cases in the world. Objective: Isolation and characterization of the SARS-CoV-2 virus causing COVID-19 at the beginning of the pandemic in Peru. Materials and methods: Twenty nasal and pharyngeal swab samples were isolated from SARS-CoV-2 using two cell lines, Vero ATCC CCL-81 and Vero E-6; virus identification was performed by RT-PCR and the onset of cytopathic effect (CPE) was evaluated by indirect immunofluorescence and subsequent identification by genomic sequencing. One of the most widely circulating isolates were selected and named the prototype strain (PE/B.1.1/28549/2020). Then 10 successive passages were performed on Vero ATCC CCL-81 cells to assess mutation dynamics. Results: We detected 11 virus isolates by cytopathic effect, and subsequently confirmed by RT-PCR and indirect immunofluorescence. Of these, six were sequenced and identified as the lineages B.1, B.1.1, B.1.1.1, and B.1.205 according to the Pango lineage nomenclature. The prototype strain corresponded to lineage B.1.1. The analysis of the strains from the successive passages showed mutations mainly at in the spike (S) protein of the virus without variation in the identity of the lineage. Conclusions: Four lineages were isolated in the Vero ATCC CCL-81 cell line. Subcultures in the same cell line show mutations in the spike protein indicating greater adaptability to the host cell and variation in pathogenicity in vitro, a behavior that allows it to have more survival success.

Avaliação do uso de estratégias não invasivas em pacientes com insuficiência respiratória por COVID-19 / Evaluation of the use of non-invasive strategies in patients with respiratory failure by COVID-19

Introdução: Durante a pandemia de COVID-19, tornou-se necessário o uso de estratégias no tratamento dos pacientes que evoluem com insuficiência respiratória aguda. Objetivo: Avaliar o uso de estratégias não invasivas no desfecho de pacientes com insuficiência respiratória aguda ou crônica agudizada por COVID-19. Métodos: Pesquisa de caráter observacional e retrospectivo por meio da coleta de dados em prontuário eletrônico com pacientes submetidos ao uso de cânula nasal de alto fluxo (CNAF) e/ou ventilação mecânica não invasiva (VNI). Resultados: 81 pacientes, sendo 70,4% (57) do sexo masculino, com 56,5 ± 14,6 anos. 49,4% (40) dos indivíduos fizeram uso de CNAF e VNI, 9,9% (8) e 40,7% (33) apenas VNI ou CNAF, respectivamente. O tempo médio de uso da CNAF foi de 4,4 ± 3,7 dias e de VNI foi de 2,7 ± 3,4 dias. Observou-se que 43 (53,1%) dos pacientes pesquisados evoluíram para intubação orotraqueal (IOT) e 40 (49,4%) para óbito. Destes, 22 encontravam-se em IOT. Houve diferença estatística quando comparados idade entre os grupos IOT e não IOT, 60,5 ± 13,9 anos vs 52,1 ± 14,2 anos (p = 0,012), respectivamente. Conclusão: O uso de VNI e/ou CNAF pode ser considerado como alternativa no tratamento de pacientes com COVID-19. Contudo, os diversos fatores intrínsecos e extrínsecos ao paciente ainda contribuem para a alta taxa de IOT e de mortalidade.

Contribution of nursing research to fighting against COVID-19 pandemic. A systematic review

Introduction: The 2019 coronavirus disease (COVID-19) pandemic, should be an opportunity to ensure greater visibility of nursing in health systems and society worldwide. Objective: Review and synthesize the patterns on COVID-19 and nursing research, identifying the main journals, country of origin, language, topics, designs, and area of applicability of the results. Materials and Methods: Systematic review. Searches in PubMed, CINAHL, LILACS, and EMBASE databases (from the inception of the pandemic to May 15, 2020) were performed. Articles of any language related were related to SARS-CoV-2 infection or COVID-19 disease and nursing in any of its roles (care, management, education, among others) and using any epidemiological design or a scientific report were included. Two reviewers independently selected the studies and extracted the data. The main findings from the included studies were summarized through narrative synthesis and descriptive tables. The characteristics of the studies were presented as absolute values and proportions. Results: Three hundred and sixty-five articles were assessed for eligibility. Thirty-eight were included, published in 28 journals. Of those, 53.57% (n=15) were nursing specific. Most articles were "narrative reviews", accounting for 23.68% (n=9). Most studies were conducted in China (n=18, 47.37%), followed by the United Kingdom and the United States. Thirty-four (89.47%) articles were published in English, followed by Portuguese and Chinese. We identified five areas of application of the results, and the most frequent was the "clinical" setting with 47.00% (n=18). Discussion: These findings are crucial to give visibility to nursing work during the emergency of the COVID-19 pandemic. Mental health was the main research topic, while the clinical setting concentrates the major number of articles. This pattern was aligned with the challenges of the initial phase of the pandemic. Conclusion: Future research should explore the current state of evidence in the main topics identified in this review and continue to give visibility to work carried out by nursing in the emergency of the COVID-19 pandemic.

Impacto da COVID-19 grave na qualidade de vida relacionada com a saúde e a incapacidade: uma perspectiva de follow-up a curto-prazo / The impact of severe COVID-19 on health-related quality of life and disability: an early follow-up perspective

RESUMO Objetivo: Avaliar a qualidade de vida relacionada com a saúde e a incapacidade no primeiro mês após a alta para domicílio de todos os sobreviventes de COVID-19 grave internados por mais de 24 horas no Serviço de Medicina Intensiva. Metódos: Estudo realizado no Serviço de Medicina Intensiva do Centro Hospitalar Universitário São João, entre 8 de outubro de 2020 e 16 de fevereiro de 2021. Aproximadamente 1 mês após a alta para domicílio, uma enfermeira com experiência em medicina intensiva realizou uma consulta telefônica a 99 sobreviventes, aplicando os questionários EuroQol Five-Dimensional Five-Level e World Health Disability Assessment Schedule 2.0 - 12 itens. Resultados: A média de idade da população estudada foi de 63 ± 12 anos, e 32,5% foram submetidos à ventilação mecânica invasiva. O Simplified Acute Physiology Score médio foi de 35 ± 14, e o Índice de Comorbilidades de Charlson foi de 3 ± 2. O tempo de internamento em medicina intensiva e no hospital foi de 13 ± 22 e 22 ± 25 dias, respectivamente. A média da Escala Visual Analógica da EuroQol foi de 65% (± 21), sendo que apenas 35,3% dos sobreviventes não apresentaram ou tiveram problemas ligeiros para realizar suas atividades habituais, a maioria com algum grau de dor/desconforto e ansiedade/depressão. O World Health Disability Assessment Schedule 2.0 - 12 itens, mostrou incapacidade marcada em retomar o trabalho habitual ou atividades comunitárias e na mobilidade. O uso de ambas as ferramentas sugeriu que o estado de saúde dos sobreviventes seria pior do que a sua percepção. Conclusão: A identificação precoce de sequelas pode ajudar a definir fluxos e prioridades para a reabilitação e reinserção após a COVID-19 grave.

ABSTRACT Objective: To assess early postdischarge health-related quality of life and disability of all survivors of critical COVID-19 admitted for more than 24 hours to na intensive care unit.. Methods: Study carried out at the Intensive Care Medicine Department of Centro Hospitalar Universitário São João from 8th October 2020 to 16th February 2021. Approximately 1 month after hospital discharge, an intensive care-trained nurse performed a telephone consultation with 99 survivors already at home applying the EuroQol Five-Dimensional Five-Level questionnaire and the 12-item World Health Organization Disability Assessment Schedule 2.0. Results: The mean age of the population studied was 63 ± 12 years, and 32.5% were submitted to invasive mechanical ventilation. Their mean Simplified Acute Physiologic Score was 35 ± 14, and the Charlson Comorbidity Index was 3 ± 2. Intensive care medicine and hospital lengths of stay were 13 ± 22 and 22 ± 25 days, respectively. The mean EuroQol Visual Analog Scale was 65% (± 21), and only 35.3% had no or slight problems performing their usual activities, most having some degree of pain/discomfort and anxiety/depression. The 12-item World Health Organization Disability Assessment Schedule 2.0 showed marked impairments in terms of reassuring usual work or community activities and mobility. The use of both tools suggested that their health status was worse than their perception of it. Conclusion: This early identification of sequelae may help define flows and priorities for rehabilitation and reinsertion after critical COVID-19.

Recientemente, se ha postulado la participación de las respuestas IL-17/Th17 en la patogénesis de la enfermedad por coronavirus 2019 (COVID-19). El objetivo de esta revisión es resumir la evidencia del papel de la IL-17/Th17 en la inmunopatogénesis del COVID-19, como sustento de la possible utilización de los inhibidores de IL-17 en el manejo terapéutico de esta infección.

SUMMARY Interleukin 17 (IL-17)-producing helper T cells (Th17) and IL-17 play an important role in the defense against extracellular bacteria and fungi; however, persistent secretion of IL-17 is also an important component in the pathogenesis of many inflammatory and autoimmune diseases. Recent evidence suggests that Th17 cells and IL-17 are also involved in the immunopathogenesis of COVID-19. This review summarizes the evidence related with the role of Th17/IL-17 in severe COVID-19, which support the possible use of IL-17/IL-17R inhibitors in the treatment of this infection.

Emergency Department Visits and Deaths from Cardiovascular Diseases at a Referral Center for Cardiology During the COVID-19 Pandemic

Abstract Background The COVID-19 pandemic has imposed measures of social distancing and, during this time, there has been an elevation in cardiovascular mortality rates and a decrease in the number of emergency visits. Objectives To assess and compare in-hospital mortality for cardiovascular diseases and emergency department visits during the COVID-19 pandemic and the same period in 2019. Methods Retrospective, single-center study that evaluated emergency visits and in-hospital deaths between March 16, 2020 and June 16, 2020, when the steepest fall in the number of emergency admissions for COVID-19 was registered. These data were compared with the emergency visits and in-hospital deaths between March 16 and June 16, 2019. We analyzed the total number of deaths, and cardiovascular deaths. The level of significance was set at p < 0.05. Results There was a 35% decrease in the number of emergency visits and an increase in the ratio of the number of deaths to the number of emergency visits in 2020. The increase in the ratio of the number of all-cause deaths to the number of emergency visits was 45.6% and the increase in the ratio of the number of cardiovascular deaths to the number of emergency visits was 62.1%. None of the patients who died in the study period in 2020 tested positive for COVID-19. Conclusion In-hospital mortality for cardiovascular diseases increased proportionally to the number of emergency visits during the COVID-19-imposed social distancing compared with the same period in 2019.

Cardiovascular Risk Assessment after COVID-19 Infection before Resuming Sports Activities - Practical Flowchart and Meta-Analysis

Abstract Background: The risk of sports-related sudden cardiac arrest after COVID-19 infection can be a serious problem. There is an urgent need for evidence-based criteria to ensure patient safety before resuming exercise. Objective: To estimate the pooled prevalence of acute myocardial injury caused by COVID-19 and to provide an easy-to-use cardiovascular risk assessment toolkit prior to resuming sports activities after COVID-19 infection. Methods: We searched the Medline and Cochrane databases for articles on the prevalence of acute myocardial injury associated with COVID-19 infection. The pooled prevalence of acute myocardial injury was calculated for hospitalized patients treated in different settings (non-intensive care unit [ICU], ICU, overall hospitalization, and non-survivors). Statistical significance was accepted for p values <0.05. We propose a practical flowchart to assess the cardiovascular risk of individuals who recovered from COVID-19 before resuming sports activities. Results: A total of 20 studies (6,573 patients) were included. The overall pooled prevalence of acute myocardial injury in hospitalized patients was 21.7% (95% CI 17.3-26.5%). The non-ICU setting had the lowest prevalence (9.5%, 95% CI 1.5-23.4%), followed by the ICU setting (44.9%, 95% CI 27.7-62.8%), and the cohort of non-survivors (57.7% with 95% CI 38.5-75.7%). We provide an approach to assess cardiovascular risk based on the prevalence of acute myocardial injury in each setting. Conclusions: Acute myocardial injury is frequent and associated with more severe disease and hospital admissions. Cardiac involvement could be a potential trigger for exercise-induced clinical complications after COVID-19 infection. We created a toolkit to assist with clinical decision-making prior to resuming sports activities after COVID-19 infection.

Abstract Introduction the COVID-19 pandemic and measures to control its expansion impacted different segments of the economy, including dentistry professionals. Objective this study analyzed the financial impact of the COVID-19 pandemic on dental technicians in Brazil. Material and method this is a descriptive cross-sectional study with the application of a questionnaire of sociodemographic and professional profile, financial impact, and effect containment measures to dental technicians in Brazil. The questionnaire was applied online on social networks between January 27 and February 15, 2021. Result 59.8% of the participants were male, with 47.5% aged up to 30 years, and 57.3% with less than 10 years of practice. The measures to contain the spread of the coronavirus had a financial impact on 89.6% of the participants: 72.0% had their work completely interrupted, 97.7% had their billing reduced, 98.2% changed their work routine, and 94.8% had higher laboratory expenses in the period. Revenue decreased between 0% and 25.0% for 41.2% and between 25.0% and 50.0% for 36.3%. In addition, 66.6% continued working during the pandemic due to their financial situation. 71.8% of the participants did not consider closing their laboratory permanently, whereas 92.2% followed hygiene protocols routinely and 21.6% made use of their financial reserves. Conclusion dental technicians were financially impacted by the COVID-19 pandemic, mainly caused by fewer working hours, revenue reduction, and higher operating costs due to the change in the biosafety routine.

Bronchoscopy in COVID-19 inpatients: experience of a university hospital in the first outbreak of the disease in Brazil

ABSTRACT Objective: To describe the indications and endoscopic findings of bronchoscopy performed at a reference university hospital for inpatients diagnosed with COVID-19 during the first outbreak of the disease in Brazil. Methods: A retrospective analysis of medical records of adult patients diagnosed with COVID-19 who underwent bronchoscopy at the intensive care units of Instituto do Coração and Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, from March to August 2020. Results: A total of 132 bronchoscopies were performed in 103 patients diagnosed with COVID-19. Mean age was 56.1±14.5 years, and distribution was similar in both sexes. More than one test was performed in 16 patients. The most frequent indications were diagnostic endoscopic evaluation and therapeutic procedures in 78.6% of cases (n=81) and material collection in 21.4% of cases (n=22). The most frequent endoscopic findings were presence of secretion or clots in 34% of cases, the presence of acute inflammatory changes in 22.3%, and tracheal wall laceration in 20.4%. In 27.2% of patients, no relevant bronchoscopic findings were observed. In three patients, bronchoscopy was indicated to assess hemoptysis, but there was only one case of active bleeding. Procedure-related complications were not observed in this group of patients. Conclusion: Bronchoscopy proved to be a safe and effective procedure to assist in treatment of COVID-19 patients, and the most frequent indications were related to investigation of airway involvement or to evaluate infectious and inflammatory pulmonary processes.

Palliative care to cancer patients: how COVID-19 pandemic could affect quality of care

ABSTRACT Objective To evaluate the impact of COVID-19 pandemic on the care delivered to hospitalized cancer patients in end-of-life. Methods A retrospective analysis of data of hospitalized patients with advanced solid tumors, who died under exclusive palliative care during first wave (March 2020 to July 2020) compared with the period previous pandemic (January 2018 to February 2020). Results A total of 190 oncologic patients were included, 161 patients before the pandemic, and 29 in the period from March 2020 to July 2020. The average hospitalization was 497.2 patients per month, before the pandemic, and dropped to an average of 46.5 in the pandemic, whereas the death rate decreased from an average of 6.3 patients per month to 4.8. Considering the benchmarks for quality of care during end-of-life care, preferences on life assistance were discussed prior to hospitalization for 34.4%, before the pandemic, and 13.8% during the pandemic (p=0.0298); 9.3% received chemotherapy 15 days prior to the date of death, before the pandemic, and 20.7%, in the pandemic (p=0.1012). Conclusion Based on the present results, despite the decrease in oncology admissions, the advanced-stage cancer patients continued to seek hospital for end-of-life care. However, we could observe in our benchmarking analyses for palliative quality of care that talks about prognosis occurred less often during the pandemic.
