Síndrome inflamatória multissistêmica em crianças infectadas por coronavírus: uma revisão integrativa / Multisystemic inflamatory syndrome in children infected by coronavirus: an integrative review / Síndrome inflamatorio multisistémico en niños infectados por coronavirus: una revisión integradora

Durante a pandemia de COVID-19, foram observadas manifestações atípicas em pacientes pediátricos em diversas regiões do mundo, e o conjunto desses sintomas caracterizou uma nova patologia denominada Síndrome Inflamatória Multissistêmica em Crianças (MIS-C), ou Síndrome Inflamatória Multissistêmica Pediátrica Temporariamente associada ao COVID-19 (PIMS- TS). O objetivo desta revisão foi analisar as manifestações clínicas e as possíveis complicações relacionadas a tal quadro inflamatório. Foi realizada uma busca por artigos científicos nas bases de dados Embase, PubMed e Web of Science, por meio da combinação dos descritores "MIS-C", "PIMS- TS" e "COVID-19". Após a análise dos artigos encontrados, e considerando critérios de inclusão e exclusão, foram selecionados 15 estudos para compor esta revisão. A maioria dos estudos mencionaram complicações gastrointestinais, cardiovasculares, respiratórias e mucocutâneas. Ademais, foram encontrados marcadores que indicavam estado inflamatório generalizado e coagulopatia. Assim, concluiu-se que MIS-C provavelmente é uma síndrome manifestada após a infecção por SARS-CoV-2, podendo ocasionar quadros mais graves, mas com baixas taxas de mortalidade.

During the COVID-19 pandemic, atypical manifestations were observed in pediatric patients in different regions of the world, and the set of these symptoms characterized a new pathology called Multisystemic Inflammatory Syndrome in Children (MIS-C), or Pediatric Multisystemic Inflammatory Syndrome Temporarily associated with COVID-19 (PIMS-TS). The purpose of this review was to analyze the clinical manifestations and possible complications related to such an inflammatory condition. A search for scientific articles was carried out in the databases Embase, PubMed and Web of Science, by combining the descriptors "MIS-C", "PIMS-TS" and "COVID-19". After analyzing the articles found, and considering inclusion and exclusion criteria, 15 studies were selected to compose this review. Most studies mentioned gastrointestinal, cardiovascular, respiratory and mucocutaneous complications. In addition, markers were found that indicated generalized inflammatory status and coagulopathy. Thus, it was concluded that MIS-C is probably a syndrome manifested after infection by SARS-CoV-2, which can cause more severe conditions, but with low mortality rates.

Durante la pandemia de COVID-19 se observaron manifestaciones atípicas en pacientes pediátricos de diferentes regiones del mundo, y el conjunto de estos síntomas caracterizó una nueva patología denominada Síndrome Inflamatorio Multisistémico en Niños (SMI-C), o Síndrome Inflamatorio Multisistémico Pediátrico Asociado Temporalmente a COVID-19 (SIPM-TS). El propósito de esta revisión fue analizar las manifestaciones clínicas y las posibles complicaciones relacionadas con dicha condición inflamatoria. Se realizó una búsqueda de artículos científicos en las bases de datos Embase, PubMed y Web of Science, combinando los descriptores "MIS-C", "PIMS- TS" y "COVID-19". Tras analizar los artículos encontrados, y teniendo en cuenta los criterios de inclusión y exclusión, se seleccionaron 15 estudios para componer esta revisión. La mayoría de los estudios mencionaron complicaciones gastrointestinales, cardiovasculares, respiratorias y mucocutáneas. Además, se encontraron marcadores que indicaban un estado inflamatorio generalizado y coagulopatía. Así pues, se concluyó que el SMI-C es probablemente un síndrome que se manifiesta tras la infección por el SARS-CoV-2, que puede causar cuadros más graves, pero con bajas tasas de mortalidad.

Modos ventilatorios usados en pacientes críticos con covid-19 en la región de Lombardía, Italia / Ventilation modes used in critical patient with COVID-19 in the region of Lombardy, Italy

RESUMEN Introducción: la covid-19 es una enfermedad donde la ventilación mecánica artificial cobra vital importancia. Se estima que el 50 % de los casos graves o críticos que requieren manejo en unidades de cuidados intensivos fallecen. Objetivos: se evaluó el impacto de los modos ventilatorios usados en pacientes con covid-19 en Lombardía, Italia, en la oxigenación, la hemodinámica y la mortalidad. Materiales y métodos: se realizó un estudio analítico longitudinal retrospectivo en 86 pacientes críticos con covid-19, en el Hospital Mayor de Crema, en Lombardía, Italia, desde el 1 de abril al 20 de mayo de 2020. Se realizaron análisis no paramétrico y de la varianza. Resultados: Hubo una supervivencia del 76,7 %. El modo utilizado tuvo igual comportamiento en occisos (BiPAP-3, PCV-4, VCRP-4, APRV-5, VCV-4) y en vivos (BiPAP-10, PCV-17, VCRP-14, APRV-15, VCV-10); test de x2 = 0,59; test de análisis de la varianza media índice PO2/FIO2 (PCV = 132), (BiPAP = 132) (VCV = 115) p = 0,924. La presión de final de espiración positiva (BiPAP-12, PCV-13, VCRP-13, APRV-13, VCV-14) con p = 0,205. PCO2 (BiPAP-55, PCV-52, VCRP-57, APRV-59, VCV-57) con p = 0,512. La tensión arterial media (BiPAP-84, PCV-83, VCRP-84, APRV-82, VCV-83) con p = 0,988. Modelos de cálculo de la presión de final de espiración positiva, según modo ventilatorio: BiPAP: PEEP = -0,0331 (índice PO2/FiO2) +18,215; PCV: PEEP = -0,0047 (índice PO2/FiO2) +13,717; VCRP: PEEP = -0,0204 (índice PO2/FiO2) +15,678; APRV: PEEP = -0,0092 (índice PO2/FiO2) +14,889. Conclusiones: la evolución del paciente crítico con covid-19 está determinada en gran medida por la ventilación mecánica invasiva; sin embargo, no existió suficiente evidencia para recomendar una u otra modalidad ventilatoria. El éxito está en conocer con exactitud las características del respirador, su modalidad y el paciente en cuestión. (AU)

ABSTRACT Introduction: COVID-19 is a disease in which mechanical ventilation acquires vital importance. It is estimated that 50 % of the serious and critical patients requiring management in intensive care units die. Objectives: to assess the impact of the ventilation modes used in patients with COVID-19 in Lombardy, Italy, on oxygenation, hemodynamics and mortality. Materials and methods: a retrospective, longitudinal, analytic study was carried out in 86 critical patients with COVID-19 who entered the Main Hospital of Crema, in Lombardy, Italy, from April 1st to May 20, 2020. Results: the survival was 76.7 %. The used mode showed the same behavior in deceased patients (BiPAP-3, PCV-4, VCRP-4, APRV-5, VCV-4) and in alive patients (BiPAP-10, PCV-17, VCRP-14, APRV-15, VCV-10). X2 = 0.59. ANOVA test index PO2/FIO2 (PCV = 132), (BiPAP = 132) (VCV=115) p = 0.924. PEEP (BiPAP-12, PCV-13, VCRP-13, APRV-13, VCV-14) p = 0.205. PCO2 (BiPAP-55, PCV-52, VCRP-57, APRV-59, VCV-57) p = 0.512. Average blood pressure (BiPAP-84, PCV-83, VCRP-84, APRV-82, VCV-83) p = 0.988. PEEP models according to ventilation mode: BiPAP: PEEP = -0.0331 (PO2/FiO2 index) +18.215. PCV: PEEP = -0.0047 (PO2/FiO2 index) + 13.717; VCRP: PEEP = -0.0204 (PO2/FiO2 index) + 15.678; APRV: PEEP = -0.0092 (PO2/FiO2 index) +14.889. Conclusion: the evolution of the critical patient with COVID-19 is determined mostly by the invasive mechanical ventilation; but we did not find evidence enough to recommend one or the other ventilation mode. The success stands in knowing accurately the characteristics of the ventilator, the ventilation modes and the patient (AU).

Desórdenes del metabolismo glucídico y síndrome metabólico en pacientes de covid-19 / Glucide metabolism disorders and metabolic syndrome in COVID-19 patients

RESUMEN El síndrome metabólico comprende un conjunto de factores de riesgo cardiovascular asociado a resistencia a la insulina, que propicia la aparición de enfermedad cardiovascular y de diabetes mellitus tipo 2. Su etiología se atribuye a la combinación de factores genéticos y ambientales, asociados al estilo de vida, que favorecen un estado proinflamatorio y protrombótico que empeora el cuadro clínico de los pacientes con covid-19. El objetivo de la revisión consistió en analizar el estado actual del conocimiento científico en las investigaciones sobre la interrelación entre los desórdenes del metabolismo glucídico y el síndrome metabólico, asociados a la condición proinflamatoria exacerbada en pacientes de covid-19. Se hicieron búsquedas en las bases de datos PubMed, SciELO, ClinicalKey y LILACS. Al proceso proinflamatorio generado por malos hábitos alimentarios, la sobrealimentación calórica de alto índice glicémico, y estilos de vida sedentarios, se atribuye un papel relevante en la patogénesis del síndrome metabólico, así como en sus posibles complicaciones en pacientes de covid-19 con comorbilidades asociadas. Es posible reducir la condición inflamatoria del síndrome metabólico mediante modificaciones en el estilo de vida y hábitos alimentarios, que prevengan la obesidad y sus efectos en la resistencia a la insulina, lo cual propicia reducir la gravedad asociada a los procesos inflamatorios inherentes (AU).

ABSTRACT Metabolic syndrome includes a set of cardiovascular risk factors associated with resistance to insulin, favoring the appearance of cardiovascular disease and diabetes mellitus type 2. Its etiology is attributed to the combination of genetic and environmental factors, associated to lifestyle, and favoring a proinflammatory and prothrombotic status that worsens the clinical characteristics of the patients with COVID-19. The objective of the review was to analyze the current state of the scientific knowledge in research on the interrelationship between glucide metabolism disorders and metabolic syndrome, associated with the exacerbated proinflammatory condition in COVID-19 patients. Searches were conducted in PubMed, SciELO, CinicalKey, and LILACS databases. A relevant role in the metabolic syndrome pathogenesis is attributed to the inflammatory process generated by poor eating habits, high caloric overfeeding, and to sedentary lifestyle, and also to possible complications with associated comorbidities in COVID-19 patients. It is possible to reduce the metabolic syndrome inflammatory condition through life style and alimentary habits changes that prevent obesity and its effects on insulin resistance and propitiate the reduction of the disease severity associated with the inherent inflammatory processes (AU).

Fracaso multiorgánico secundario a infección por coronavirus no COVID-19 / Multiple-organ failure as a result of non-COVID-19 coronavirus infection

Las infecciones por coronavirus son habituales en los pacientes pediátricos. Por lo general, producen un cuadro clínico leve de infección del tracto respiratorio superior que no suele afectar a los pulmones, salvo en prematuros y niños con enfermedades crónicas de base. Excepcionalmente, afectan a otros órganos (corazón, cerebro, tracto gastrointestinal) e incrementan su gravedad.En relación con la coincidencia temporal con el inicio de la actual pandemia por el nuevo beta coronavirus (SARS-CoV-2), responsable de su enfermedad asociada (COVID-19), se presenta el caso clínico de un paciente de 5 años con fracaso multiorgánico y secuelas neurológicas por afectación bulbar y trombosis vascular ocasionados por un alfa coronavirus (CoV-NL63) debido a su gravedad y excepcionalidad

Coronavirus infections (CoV) are common in pediatric patients. In general, they produce a mild clinical presentation consisting of an upper respiratory tract infection that does not usually infect the lungs, with the exception of preterm infants and children with chronic diseases. These infections exceptionally affect other organs (heart, brain, gastrointestinal tract), thus increasing their severity.In relation to the temporal coincidence with the beginning of the current situation of pandemic by the new beta coronavirus SARS-CoV-2 responsible for its associated disease (COVID-19), this study presents a clinical case of a 5-year-old patient showing multiple-organ failure and neurological sequelae due to bulbar injury and vascular thrombosis caused by an alpha coronavirus (CoV-NL63) due to its severity and exceptionality

Modelo temporal del comportamiento de pacientes críticos con covid-19 durante su estadía en cuidados intensivos. Lombardía, Italia / Temporal model of the behavior of critically ill patients with COVID-19 during their staying in intensive care. Lombardy, Italy

RESUMEN Introducción: una serie temporal es el producto de la observación de una variable en el tiempo. Es una herramienta matemática que se aplica con frecuencia en la salud. No se han elaborado modelos temporales que predigan el comportamiento de los pacientes durante su ingreso en la Unidad de Cuidados Intensivos. Objetivos: crear una serie temporal que permita predecir el comportamiento, durante su ingreso en la Unidad de Cuidados Intensivos, de pacientes graves producto de la covid-19 en la región de Lombardía, Italia. Materiales y métodos: analítico, longitudinal prospectivo con un grupo de pacientes críticos que ingresaron del 1 de abril al 1 de mayo de 2020, con diagnóstico de covid-19, en el Hospital Mayor de Crema, en la región de Lombardía, Italia. El universo estuvo constituido por 28 pacientes y se trabajó con el total de ellos. Resultados: composición por sexo: 48 % masculino. Media de edad: 83 años. Serie temporal: Modelo 1 que ajusta (Hold) PO2/FiO2 p = 0,251; Modelo 2 (ARIMA) SatO2/FiO2 p = 0,674 (en los dos primeros modelos el resultado se incrementó con los días, siguiendo un comportamiento predecible); Modelo 3 (ARIMA) p = 0,406 (en este caso, el resultado esperado decreció a medida que transcurrió el tiempo). Las funciones obtenidas permiten calcular el valor esperado según el día desde el ingreso. Conclusiones: predecir la evolución del paciente en la Unidad de Cuidados Intensivos permitió detectar tempranamente aquellos con una curva inesperada y dirigir hacia a ellos las terapéuticas más agresivas (AU).

ABSTRACT Introduction: a time series is the product of the observation of a variable in time. It is a mathematical tool frequently applied in health. No temporal models have been developed to predict patients' behavior during their staying in the Intensive Care Unit. Objectives: to create a time series allowing to predict the behavior of seriously-ill patients due to COVID-19, during their staying in the Intensive Care Unit in the region of Lombardy, Italy. Materials and methods: analytic, longitudinal prospective study with a group of critical patients who were admitted from April 1st to May 1st, with COVID-19 diagnosis, to Ospedale Maggiore di Crema, in the Lombardy region, Italy. The universe was formed by 28 patients and all of them were worked on. Results: 48% of patients were male. Average age: 83 years; Time series: Model 1 holding PO2/FiO2 p = 0.251; Model 2 (ARIMA) SatO2/FiO2 p = 0.674 (in the two first models the result increased with the days, following a predictable behavior=; Model 3 (ARIMA) p = 0.406 (in this case the expected result decreased as time passed). The obtained functions allow to calculate the expected value according to the day from the admission. Conclusions: predicting patient's evolution in the Intensive Care Unit allowed early detecting those with unexpected curves and targeting more aggressive therapies toward them (AU).

Repercusión de la covid-19 en la salud materno-infantil / Covid-19 repercussions on maternal and infantile health

RESUMEN El año 2020 ha sorprendido al planeta con la pandemia de la covid-19. Este artículo tiene como objetivo reflexionar sobre las repercusiones del nuevo coronavirus en la salud materno-infantil. Pese al poco tiempo transcurrido desde el inicio de la pandemia, en las embarazadas con covid-19 se han descrito algunas comorbilidades, así como alteraciones placentarias, abortos espontáneos, muertes fetales y maternas, e incremento en los partos por cesárea y nacimientos pretérminos. Los riesgos potenciales demandarán una vigilancia estrecha del comportamiento del embarazo en el futuro inmediato. Por otra parte, del total de la población afectada por la covid-19, los pacientes en edad pediátrica representan entre el 1 y el 2 %, y la mayoría presentan manifestaciones clínicas leves. No obstante, en los menores de un año cerca del 10 % puede evolucionar a formas severas o críticas. De especial interés ha sido la presentación del síndrome inflamatorio multisistémico en niños, debido a su gravedad y riesgo para la vida. En los recién nacidos, la infección por SARS-CoV-2 podría asociarse a dos formas, de acuerdo al momento de adquisición: la covid perinatal y la postnatal. Hasta el momento, las evidencias sobre la existencia de la vía de transmisión vertical son insuficientes, pero no pueden ser descartadas. En conclusión, por tratarse de un fenómeno en desarrollo, aún quedan muchas interrogantes sobre los efectos de la covid-19 en la salud materna e infantil, que demandarán en los próximos meses un gran esfuerzo por parte de investigadores, médicos de asistencia y directivos (AU).

ABSTRACT The year 2020 has surprised the planet with the covid-19 pandemics. This article is aimed to reflect on the repercussions of the novel coronavirus on maternal and infantile health. Despite of the short time elapsed from the onset of the pandemics, some comorbidities have been described in pregnant women with COVID-19, as well as placental anomalies, spontaneous abortions, stillbirths, maternal deaths, and an increasing number on cesarean section and preterm births. The potential risk will demand a close surveillance of pregnancy behavior in the near future. Moreover, pediatric patients are among 1 and 2% of the population affected by COVID-19, and most of them show mild clinical signs. Nevertheless, about 10% of the children aged less than a year may evolve to severe and critical forms. The multisystem inflammatory syndrome in children has been of special interest, due to its severity and risk for life. In newborns, SARS-CoV-2 infection could be associated to two forms according to the acquisition time: perinatal and postnatal COVID-19. Up to the moment, evidences on vertical transmission are insufficient, but they could not be discarded. In conclusion, as this is an ongoing phenomenon, many questions about the effects of COVID-19 on maternal and infantile health are pending; they will demand a crucial effort by researchers, health providers and decision makers (AU).

Aplicación de un modelo cubano predictivo de mortalidad en pacientes graves por covid-19 en Lombardía, Italia / Application of a Cuban mortality-predictive model in seriously-ill patients with Covid-19 in Lombardy, Italy

RESUMEN Introducción: la neumonía por covid-19 es la enfermedad infecciosa que ha revolucionado al mundo en los últimos meses. El diagnóstico pasa por varios momentos: el cuadro clínico, la analítica sanguínea y las imágenes. La estratificación del riesgo de muerte es muy importante para optimizar los recursos. Objetivos: validar un modelo matemático cubano predictivo de mortalidad en pacientes ingresados por covid-19. Materiales y métodos: estudio de cohorte con 191 pacientes, que ingresaron graves en el Hospital Mayor de Crema, en la provincia de Cremona, región de Lombardía (Italia), en el período de abril a mayo de 2020. El universo estuvo constituido por 191 pacientes, y no se tomó muestra alguna. Las variables fueron: edad, estado del paciente, niveles de creatinina plasmática, frecuencia respiratoria, frecuencia cardiaca, presión arterial, niveles de oxígeno y de dióxido de carbono en sangre, valor del sodio y de hemoglobina. Resultados: mortalidad del 22 % en pacientes graves y críticos, con media de la edad (grupo 1: 59 años) (grupo 2: 73 años); t-Student = 0,00. Test de Hosmer-Lemenshow (0,766) con elevado ajuste. Sensibilidad = 93 %. Área bajo la curva = 0,957. Porcentaje de aciertos en la regresión logística de 86,4 % y en la red neuronal de 91,2 %. Media del modelo por grupos (grupo 1: 4 458) (grupo 2: 2 911) t-Student = 0,00. Conclusiones: el modelo demostró ser muy útil en el flujograma de pacientes atendidos con la covid-19. Permitió detectar tempranamente (a los cinco días del ingreso) los pacientes con alto riesgo de muerte y discriminar aquellos que no tendrían este riesgo, de manera que pudieran ser tratados en unidades de cuidados mínimos (AU).

ABSTRACT Introduction: COVID-19 pneumonia is an infectious disease that has revolutionized the world in the last months. The diagnosis goes thought several moments: clinical features, blood analytic and images. Death risk stratification is very important to optimize resources. Objective: to validate the Cuban mathematic predictive model of mortality in patients admitted due to COVID-19. Materials and methods: cohort study with 191 seriously-ill patients who were admitted to Maggiore di Crema Hospital, Cremona, Lombardy region, Italy, in the period April-May 2020. The universe were 191 patients and no sample was chosen. The variables were: age; patient's status; plasma creatinine levels; respiratory rate; heart rate; arterial pressure; blood oxygen and carbon dioxide levels; values of sodium and hemoglobin. Results: 22 % of mortality in seriously-ill and critical patients, with average age in Group 1: 59 years, in Group 2: 73 years; t-Student = 0.00. Hosmer-Lemenshow test (0.766) with high adjustment. Sensitivity= 93 %. Area below the curve=0.957. Success percentage in logistic regression of 86.4 % and 91.2 % in the neuronal net.

La hipertensión arterial (61,29 por ciento) y el hipotiroidismo (38,71 por ciento) fueron las comorbilidades más frecuentes. El 70,27 por ciento de los pacientes presentaron manifestaciones cardiovasculares: hipertensión arterial (65,38 por ciento), trastornos del ritmo cardiaco (57,69 por ciento) y el síndrome de Raynaud (53,85 por ciento). El 80,0 por ciento de los pacientes masculinos presentaron manifestaciones cardiovasculares, al igual que el 80,64 por ciento de los casos con enfermedad reumática, COVID-19 y comorbilidades asociadas. Conclusiones: Las manifestaciones cardiovasculares se presentaron con elevada frecuencia en los pacientes reumáticos con diagnóstico de COVID-19, sobre todo pacientes masculinos con comorbilidades asociadas. Las manifestaciones cardiovasculares más frecuentes fueron la hipertensión arterial, los trastornos del ritmo y el síndrome de Raynaud(AU)

Introduction: COVID-19 generates a wide range of clinical manifestations in general. In patients with rheumatic diseases, in addition to respiratory manifestations, joint, dermatological, general and cardiovascular manifestations, among others, stand out. Objective: To identify the cardiovascular manifestations that most frequently occur in patients with rheumatic diseases and COVID-19. Methods: A basic, non-experimental research was carried out, with an exploratory, descriptive and explanatory scope. Universe made up of 37 patients with a previous diagnosis of rheumatic disease and a confirmed diagnosis of COVID-19. Directed observation and documentary review were used as research techniques to identify the presence of cardiovascular manifestations in this type of patient. Results: Predominance of female patients (59.56 percent), diagnosed with osteoarthritis (72.97 percent) and rheumatoid arthritis (72.97 percent) and with associated comorbidities (83.78 percent). Hypertension (61.29 percent) and hypothyroidism (38.71 percent) were the most frequent comorbidities. 70.27 percent of the patients presented cardiovascular manifestations, predominantly arterial hypertension (65.38 percent), rhythm disorders (57.69 percent) and Raynaud´s syndrome (53.85 percent). 80.0 percent of the male patients presented cardiovascular manifestations, as did 80.64 percent of the cases with rheumatic disease, COVID-19 and associated comorbidities. Conclusions: Cardiovascular manifestations occurred with high frequency in rheumatic patients diagnosed with COVID-19; being more frequent in male patients and with associated comorbidities. High blood pressure, rhythm disorders and Raynaud's syndrome were the most frequent(AU)

Relations between the ocular surface and SARS-CoV-2 / Relações entre superfície ocular e SARS-CoV-2

ABSTRACT Introduction: The SARS-CoV-2 pandemic has been a major challenge for the international scientific community. Since its inception, studies aiming to describe pathophysiological aspects and clinical manifestations of the disease have been conducted, raising hypotheses and confirming possible associations. One aspect of this scientific medical production is the role of the ocular surface as a means of transmission and clinical presentation of viral syndrome. Objectives: To analyze the role of the ocular surface in transmission, pathophysiology, and clinical manifestations of SARS-CoV-2, by means of a systematic review. Methods: The search was carried out in three databases: Cochrane, PubMed Central Journals and MEDLINE, using the following descriptors: "COVID-19, ophthalmology". The filters last five years and studies on humans resulted in 32 studies; in that 12 were excluded for not meeting the purpose of the study. Results: There are still few published studies on the relation between SARS-CoV-2 and the ocular route. Most studies showed an association between the presence of nonspecific ocular manifestations and infection by the new coronavirus, with limitations in the number of patients analyzed and the methodology adopted. Hypotheses about the pathophysiological role are largely anchored in the association of SARS-CoV and the ocular surface evaluated in the past. Comments: The results found are still not sufficient to confirm the role of the ocular surface in the pathophysiology of the disease. Most of these preliminary studies are of considerable importance in raising hypotheses based on the medical analysis of the patients studied. However, larger studies with standardized methodology for diagnostic protocol and laboratory analysis of the individuals assessed are required.

RESUMO Introdução: A pandemia da SARS-CoV-2 tem sido um grande desafio para a comunidade científica internacional. Desde seu surgimento, estudos com a intenção de descrever os aspectos fisiopatológicos e as manifestações clínicas da doença vêm sendo conduzidos, levantando hipóteses e confirmando possíveis associações. Um dos temas dessa produção médica científica é o papel da superfície ocular como meio de transmissão e apresentação clínica da síndrome viral. Objetivo: Analisar o papel da superfície ocular na transmissão, na fisiopatologia e nas manifestações clínicas de SARS-CoV-2, através de uma revisão sistemática. Realizou-se a busca em três bancos de dados Cochrane Database, PubMed® e MEDLINE®, utilizando os descritores "COVID-19 e ophthalmology". Foram definidos como filtros o artigo ter sido publicado nos últimos 5 anos e estudo realizado em humanos, tendo sido encontrados 32 artigos. Destes, foram excluídos 12 por não corresponderem ao objetivo do estudo. Resultados: Ainda são poucos os estudos publicados sobre a relação entre o coronavírus 2 da síndrome respiratória aguda grave (SARS-CoV-2) e a via ocular. A maioria dos estudos mostrou associação entre a presença de manifestações oculares inespecíficas e a infecção pelo novo coronavírus, com limitações no número de pacientes analisados e na metodologia adotada. Hipóteses sobre o papel fisiopatológico se ancoram, em grande parte, na associação estudada entre o SARS-CoV-2 e a superfície ocular no passado. Comentários: Os resultados encontrados ainda não são suficientes para confirmar o papel da superfície ocular na fisiopatologia da doença. Grande parte desses estudos preliminares têm importância considerável ao levantar hipóteses baseadas na análise clínica dos pacientes estudados. No entanto, são necessários estudos maiores e com metodologia padronizada para protocolo diagnóstico e análise laboratorial dos indivíduos avaliados.

Abstract Objective: To identify, in scientific literature, the relationship of obesity as an aggravating risk factor for morbidity by COVID-19. Methods: This is a bibliographic and integrative literature review study, in Brazilian Portuguese, English and Spanish languages, through PICo strategy, in the PubMed, Scopus, Web of Science, Embase and VHL databases, held from May to June 2020. Primary articles conducted with adults, available in full, published during the period 2019 to 2020, in Brazilian Portuguese, English and Spanish were included. Case reports, clinical cases, dissertations, theses, the already selected in the search in another database and that did not answer the question of the search were excluded. Results: The selection resulted in nine studies. Four studies - 44.4% (E3, E5, E6 and E7) - presented the prevalence of obesity in adults hospitalized by COVID-19. Two studies - 22.2% (E6, E9) - associated obesity with the development of severe COVID-19. Three studies - 33.3% (E1, E4 and E7) - associated obesity with the need for mechanical ventilation. Three studies - 33.3% (E2, E4 and E8) - associated obesity with mortality due to COVID-19. Conclusion: Obesity is a chronic non-communicable disease, being a risk factor considered important for the worsening of COVID-19 disease, however, it is preventable, because healthy lifestyle habits can reduce the severe picture of COVID-19 infection.

Manifestaciones Orales de la Infección por COVID-19 / Oral Manifestations of COVID-19

RESUMEN: El 8 de enero de 2020, el Centro Chino para el Control y Prevención de Enfermedades anunció oficialmente la identificación de una nueva cepa de coronavirus (SARS-CoV-2) como el patógeno causante de la pandemia mundial de COVID-19. Las principales manifestaciones clínicas producidas por SARS-CoV-2 se encuentran ampliamente descritas en la literatura, sin embargo, la información acerca de las alteraciones que podrían producirse a nivel oral, es escasa. Se ha sugerido que la cavidad oral es un perfecto hábitat para la invasión por SARS-CoV-2 debido a la especial afinidad que tiene el virus por células con los receptores para la enzima convertidora de angiotensina (ECA2) como son las del tracto respiratorio, mucosa oral, lengua y glándulas salivales, pudiendo afectar, de este modo, el funcionamiento de las glándulas salivales, las sensaciones del gusto, olfato y la integridad de la mucosa oral. El nuevo coronavirus tendría la capacidad de alterar el equilibrio de la microbiota oral, lo que sumado a un sistema inmune deprimido permitiría la colonización por infecciones oportunista. Se ha establecido que un correcto higiene oral podría disminuir la incidencia y gravedad de las principales complicaciones del COVID-19. El objetivo de este estudio es realizar una revisión y análisis de la evidencia disponible en relación a las manifestaciones orales a nivel de las mucosas, trastornos de las glándulas salivales y alteraciones en el sistema olfatorio y gustativo en el contexto de la infección por SARS-CoV-2.

ABSTRACT: On January 8, 2020, the Chinese Center for Disease Control and Prevention officially reported the identification of a new strain of coronavirus (SARS-CoV-2) as the pathogen causing the global COVID-19 pandemic. The main clinical manifestations produced by SARS-CoV-2 are well described in the literature. However, the information about oral manifestations is limited. It has been suggested that the oral cavity is a perfect habitat for SARS-CoV-2 invasion due to the special affinity that the virus has for cells with the receptors for the converted angiotensin enzyme (ACE2), present in the respiratory tract, oral mucosal, tongue and salivary glands, thus being able to affect the functioning of the salivary glands, sensations of taste, smell and integrity of the oral mucosa. The new coronavirus could have the ability to alter the balance of the oral microbiota, which added to a depressed immune system would allow opportunistic infections colonization. It has been established that correct oral hygiene could decrease the incidence and severity of the main complications of COVID-19. The objective of this study is to review and analyze the available evidence in relation to oral manifestations at the mucosa, salivary glands disorders and olfactory and gustatory alterations in the context of SARS-CoV-2 infection.

Coronary artery bypass graft during the covid-19 pandemic

Abstract Since the beginning of the coronavirus disease (COVID-19) pandemic, in March 2020, the number of people infected with COVID-19 worldwide increases continuously. Brazil is being followed with great concern in the international media, as it can, very soon, be the epicenter of the pandemic. Initial surgical data suggest that patients who acquire COVID-19 in the perioperative period are prone to a higher morbidity and mortality, however, evidence in cardiac surgery is still scarce. This article aims to aggregate to the growing evidence suggesting that perioperative infection with severe acute respiratory syndrome coronavirus 2 contributes to a more morbid evolution of the case.

Olfactory and taste disorders in COVID-19: a systematic review / Desordens olfativas e gustativas na COVID-19: uma revisão sistemática

Abstract Introduction: The SARS-CoV-2 virus causes COVID-19, and it is responsible for the largest pandemic since the 1918 H1N1 influenza outbreak. The classic symptoms of the disease have been well defined by the World Health Organization; however, olfactory/gustatory disorders have been reported in some studies, but there are still several missing points in the understanding and in the consensus about the clinical management of these cases. Objective: To identify evidence in the scientific literature about olfactory/gustatory disorders, their clinical presentation, prevalence and possible specific treatments associated with COVID-19. Methods: A systematic review of articles published up to April 25, 2020 was performed in Medline, Cochrane Clinical Trials, ScienceDirect, Lilacs, Scopus and Google Schoolar, OpenGrey.eu, DissOnline, The New York Academy of Medicine and Reasearch Gate. Inclusion criteria: (1) Studies on patients with COVID-19; (2) Records of COVID-19 signs/symptoms, and olfactory/gustatory functions. Exclusion criteria: (1) Studies on non-human coronavirus; (2) Review articles; (3) Experimental studies (in animals or in vitro); (4) Olfactory/gustatory disorders initiated prior to SARS-CoV-2 infection. The risk assessment of bias of the selected studies was performed using the Newcastle-Ottawa scale. Results: Six articles from the 1788 records met the inclusion criteria and were analyzed. A total of 1457 patients of different ethnicities were assessed; of them, 885 (60.7%) and 822 (56.4%) had smell and taste disorders, respectively, with women being most often affected. There were olfactory/gustatory disorders even without nasal obstruction/rhinorrhea and beginning even before the signs/symptoms of COVID-19; the recovery of smell/taste, when it occurs, usually happened in the first two weeks after COVID-19 resolution. There is evidence that olfactory/gustatory disorders are strong predictors of infection by SARS-CoV-2, and it is possible to recommend patient isolation, as early as of the medical consultation, preventing the spread of the virus. No scientific evidence has been identified for effective treatments for any of the disorders. Conclusion: Olfactory/gustatory disorders may occur at varying intensities and prior to the general symptoms of COVID-19 and should be considered as part of the clinical features of COVID-19, even in mild cases. There is still no scientific evidence of specific treatments for such disorders in COVID-19 disease.

Resumo Introdução: O vírus SARS-CoV-2 causa a COVID-19 e é responsável pela maior pandemia desde o surto de influenza H1N1 de 1918. Os sintomas clássicos da doença já foram bem definidos pela Organização Mundial da Saúde; entretanto, distúrbios olfativo-gustativos têm sido relatados em alguns estudos, mas ainda com várias lacunas no entendimento e no consenso sobre a condução clínica desses casos. Objetivo: Identificar evidências na literatura científica sobre os distúrbios olfativo-gustativos acerca da apresentação clínica, prevalência e possíveis tratamentos específicos associados à COVID-19. Método: Revisão sistemática de artigos publicados até 25 de abril de 2020 nas bases de dados: Medline, Cochrane Clinical Trials, ScienceDirect, Lilacs, Scopus e Google Schoolar, OpenGrey.eu, DissOnline, The New York Academy of Medicine e Research Gate. Foram critérios de inclusão: 1) Estudos com indivíduos com COVID-19; 2) Registro dos sinais/sintomas da COVID-19 e das funções olfativo-gustativa. Foram critérios de exclusão: 1) Estudos sobre coronavírus não humano; 2) Artigos de revisão; 3) Estudos experimentais (em animais ou in vitro); 4) Distúrbios olfativos-gustativos iniciados previamente à infecção pelo SARS-CoV-2. A avaliação de risco de viés dos estudos selecionados foi feita por meio da escala de Newcastle-Ottawa. Resultados: Seis artigos dos 1.788 registros foram selecionados. Um total de 1.457 pacientes de diversas etnias foi avaliado; desses, 885 (60,7%) apresentaram perda do olfato e 822 (56,4%) perda do paladar, sendo as mulheres as mais afetadas. Os distúrbios olfativo-gustativos estiveram presentes mesmo sem obstrução nasal/rinorreia e com início mesmo antes dos sinais/sintomas clínicos da COVID-19; a recuperação do olfato/paladar, quando ocorre, geralmente se dá nas duas primeiras semanas após a resolução da doença. Há evidências de que os distúrbios olfativo-gustativos sejam fortes preditores de infecção pelo SARS-CoV-2, podendo-se recomendar o isolamento do paciente, já a partir da consulta médica, para evitar a disseminação do vírus. Não foram identificadas evidências científicas para tratamentos eficazes para qualquer dos distúrbios. Conclusão: Podem ocorrer distúrbios olfativo-gustativos em intensidades variáveis e prévios aos sintomas gerais da COVID-19, devem ser considerados como parte dos sintomas da doença, mesmo em quadros leves. Não há ainda evidências científicas de tratamentos específicos para tais distúrbios na COVID-19.
