RESUMO
ABSTRACT Objective To review the long-term outcomes (functional status and psychological sequelae) of survivors of critical illnesses due to epidemic viral pneumonia before the COVID-19 pandemic and to establish a benchmark for comparison of the COVID-19 long-term outcomes. Methods This systematic review of clinical studies reported the long-term outcomes in adults admitted to intensive care units who were diagnosed with viral epidemic pneumonia. An electronic search was performed using databases: MEDLINE®, Web of Science™, LILACS/IBECS, and EMBASE. Additionally, complementary searches were conducted on the reference lists of eligible studies. The quality of the studies was assessed using the Newcastle-Ottawa Scale. The results were grouped into tables and textual descriptions. Results The final analysis included 15 studies from a total of 243 studies. This review included 771 patients with Influenza A, Middle East Respiratory Syndrome, and Severe Acute Respiratory Syndrome. It analyzed the quality of life, functionality, lung function, mortality, rate of return to work, rehospitalization, and psychiatric symptoms. The follow-up periods ranged from 1 to 144 months. We found that the quality of life, functional capacity, and pulmonary function were below expected standards. Conclusion This review revealed great heterogeneity between studies attributed to different scales, follow-up time points, and methodologies. However, this systematic review identified negative long-term effects on patient outcomes. Given the possibility of future pandemics, it is essential to identify the long-term effects of viral pneumonia outbreaks. This review was not funded.

RESUMO
Background: The COVID-19 pandemic represented a challenge in medical care. A tool would be very useful to establish the prognosis of in-hospital death that is reliable and can be applied to the Mexican population entitled to the IMSS. Objective: To propose a prognostic scale to stratify patients with viral pneumonia COVID-19 in the emergency services. Material and methods: A nested case-control study was conducted in a cohort of patients who were consecutively admitted to the emergency department with viral pneumonia COVID-19. The cases were those patients who died, and the controls were those who were discharged due to health improvement. An association analysis was performed between the variables with significant differences between groups. Subsequently, the association was adjusted using a multivariate logistic regression model, from which the prognostic scale was developed. Results: A total of 70 subjects with COVID-19 were included, 34 cases and 36 controls. Chronic diseases, smoking, severe pulmonary involvement diagnosed by tomography, leukocytosis, and pulse oximetry less than 80% with were associated with in-hospital mortality; Odds Ratio (OR) of >1.1. Vaccination was a protective factor (OR = 0.04, CI95%: 0.01-0.16). A score greater than 3 points on the prognostic scale predicts in-hospital mortality with a specificity of 0.86 and a sensitivity of 0.73. Conclusions: The proposed prognostic scale can be a useful tool in the classification of patients with COVID-19 viral pneumonia in the emergency room services of secondary care level Hospitals.
Introducción: la pandemia por COVID-19 representó un reto en la atención médica. Sería de gran utilidad una herramienta para establecer el pronóstico de muerte intrahospitalaria que sea confiable y pueda aplicarse a la población mexicana derechohabiente del Instituto Mexicano del Seguro Social. Objetivo: proponer una escala pronóstica para estratificar a los pacientes con neumonía viral por COVID-19 en los servicios de urgencias de los hospitales de segundo nivel. Material y métodos: se realizó un estudio de casos y controles anidado en una cohorte de pacientes adultos que fueron admitidos consecutivamente en el servicio de Urgencias con diagnóstico de neumonía viral por COVID-19. Los casos fueron aquellos pacientes que fallecieron y los controles aquellos que fueron egresados de la unidad por mejoría. Se realizó un análisis de asociación ente las variables con diferencias significativas entre ambos grupos, se ajustó la asociación mediante un modelo de regresión logística multivariada a partir del cual se elaboró la escala pronóstica. Resultados: se incluyeron en total 70 personas con COVID-19, 34 casos y 36 controles. Se asociaron a la mortalidad intrahospitalaria: las enfermedades crónicas, el tabaquismo, la afectación pulmonar severa diagnosticada por tomografía, la leucocitosis y la oximetría de pulso menor a 80% con una razón de Momios (RM) de > 1.1. La vacunación fue un factor protector (RM: 0.29, IC95%: 0.11-0.80). Un puntaje mayor a 3 puntos en la escala pronóstica predice la mortalidad intrahospitalaria (sensibilidad: 0.73, especificidad: 0.86). Conclusiones: la escala pronóstica propuesta puede ser una herramienta útil en la clasificación de los pacientes con neumonía viral por COVID-19 en los servicios de urgencias de los hospitales de segundo nivel de atención.

ABSTRACT Objective: To identify factors associated with prolonged weaning and mortality in critically ill COVID-19 patients admitted to ICUs and under invasive mechanical ventilation. Methods: Between March of 2020 and July of 2021, we retrospectively recorded clinical and ventilatory characteristics of critically ill COVID-19 patients from the day of intubation to the outcome. We classified the patients regarding the weaning period in accordance with established criteria. A logistic regression analysis was performed to identify variables associated with prolonged weaning and mortality. Results: The study involved 303 patients, 100 of whom (33.0%) had a prolonged weaning period. Most of the patients were male (69.6%), 136 (44.8%) had more than 50% of pulmonary involvement on chest CT, and 93 (30.6%) had severe ARDS. Within the prolonged weaning group, 62% died within 60 days. Multivariate analysis revealed that lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were significantly associated with prolonged weaning, whereas age and prolonged weaning were significantly associated with mortality. Conclusions: Prolonged weaning can be used as a milestone in predicting mortality in critically ill COVID-19 patients. Lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were identified as significant predictors of prolonged weaning. These results might provide valuable information for healthcare professionals when making clinical decisions regarding the management of critically ill COVID-19 patients who are on mechanical ventilation.
RESUMO Objetivo: Identificar fatores associados ao desmame prolongado e à mortalidade em pacientes críticos com COVID-19 admitidos em UTI e sob ventilação mecânica invasiva. Métodos: Entre março de 2020 e julho de 2021, registramos retrospectivamente as características clínicas e ventilatórias de pacientes críticos com COVID-19 desde o dia da intubação até o desfecho. Os pacientes foram classificados quanto ao período de desmame de acordo com critérios estabelecidos. Foi realizada análise de regressão logística para identificar variáveis associadas ao desmame prolongado e à mortalidade. Resultados: O estudo incluiu 303 pacientes, 100 dos quais (33,0%) apresentaram período de desmame prolongado. A maioria dos pacientes era do sexo masculino (69,6%), 136 (44,8%) apresentaram mais de 50% de acometimento pulmonar na TC de tórax, e 93 (30,6%) apresentaram SDRA grave. No grupo desmame prolongado, 62% foram a óbito em 60 dias. A análise multivariada revelou que o acometimento pulmonar maior que 50% na TC e a demora na primeira tentativa de retirada da ventilação mecânica após a intubação apresentaram associação significativa com o desmame prolongado, enquanto a idade e o desmame prolongado apresentaram associação significativa com a mortalidade. Conclusões: O desmame prolongado pode ser utilizado como marco na predição de mortalidade em pacientes críticos com COVID-19. O acometimento pulmonar maior que 50% na TC e a demora na primeira tentativa de retirada da ventilação mecânica após a intubação foram identificados como preditores significativos de desmame prolongado. Esses resultados podem fornecer informações valiosas para os profissionais de saúde na tomada de decisões clínicas sobre o manejo de pacientes críticos com COVID-19 e em ventilação mecânica.

BACKGROUND: Approximately 5% of COVID-19 patients develop respiratory failure and need ventilatory support, yet little is known about the impact of mechanical ventilation strategy in COVID-19. Our objective was to describe baseline characteristics, ventilatory parameters, and outcomes of critically ill patients in the largest referral center for COVID-19 in Sao Paulo, Brazil, during the first surge of the pandemic. METHODS: This cohort included COVID-19 patients admitted to the intensive care units (ICUs) of an academic hospital with 94 ICU beds, a number expanded to 300 during the pandemic as part of a state preparedness plan. Data included demographics, advanced life support therapies, and ventilator parameters. The main outcome was 28-day survival. We used a multivariate Cox model to test the association between protective ventilation and survival, adjusting for PF ratio, pH, compliance, and PEEP. RESULTS: We included 1503 patients from March 30 to June 30, 2020. The mean age was 60 ± 15 years, and 59% were male. During 28-day follow-up, 1180 (79%) patients needed invasive ventilation and 666 (44%) died. For the 984 patients who were receiving mechanical ventilation in the first 24 h of ICU stay, mean tidal volume was 6.5 ± 1.3 mL/kg of ideal body weight, plateau pressure was 24 ± 5 cmH2O, respiratory system compliance was 31.9 (24.4-40.9) mL/cmH2O, and 82% of patients were ventilated with protective ventilation. Noninvasive ventilation was used in 21% of patients, and prone, in 36%. Compliance was associated with survival and did not show a bimodal pattern that would support the presence of two phenotypes. In the multivariable model, protective ventilation (aHR 0.73 [95%CI 0.57-0.94]), adjusted for PF ratio, compliance, PEEP, and arterial pH, was independently associated with survival. CONCLUSIONS: During the peak of the epidemic in Sao Paulo, critically ill patients with COVID-19 often required mechanical ventilation and mortality was high. Our findings revealed an association between mechanical ventilation strategy and mortality, highlighting the importance of protective ventilation for patients with COVID-19.
RESUMO
OBJECTIVE: To define diagnostic criteria for coronavirus disease 2019 (COVID-19) on computed tomography (CT); to study the correlation between CT and polymerase chain reaction (PCR) testing for infection with severe acute respiratory syndrome coronavirus 2; and to determine whether the extent of parenchymal involvement and the need for mechanical ventilation are associated with the CT findings and clinical characteristics of patients with COVID-19. MATERIALS AND METHODS: This was a retrospective study of 155 patients with COVID-19 treated between March and May 2020. We attempted to determine whether the CT findings correlated with age and clinical variables, as well as whether the need for mechanical ventilation correlated with the extent of the pulmonary involvement. RESULTS: On average, the patients with COVID-19 were older than were those without (mean age, 54.8 years vs. 45.5 years; p = 0.031). The most common CT finding (seen in 88.6%) was ground-glass opacity, which correlated significantly with a diagnosis of COVID-19 (p = 0.0001). The CT findings that correlated most strongly with the need for mechanical ventilation were parenchymal bands (p = 0.013), bronchial ectasia (p = 0.046), and peribronchovascular consolidations (p = 0.012). The presence of one or more comorbidities correlated significantly with more extensive parenchymal involvement (p = 0.023). For the diagnosis of COVID-19, CT had a sensitivity of 84.3%, a specificity of 36.7%, and an accuracy of 73.5% (p = 0.012 vs. PCR). CONCLUSION: The patterns of CT findings are useful for the diagnosis of COVID-19 and the evaluation of disease severity criteria. The presence of any comorbidity is associated with greater severity of COVID-19.
OBJETIVO: Definir os critérios diagnósticos da COVID-19 na tomografia computadorizada (TC), estudar a concordância entre a TC e o PCR e determinar a associação da extensão do envolvimento parenquimatoso e ventilação mecânica com os achados tomográficos e características clínicas da amostra. MATERIAIS E MÉTODOS: Estudo de 155 pacientes com COVID-19 atendidos entre março e maio de 2020. Tentamos determinar se os achados da TC se correlacionavam com a idade e variáveis clínicas, bem como se a necessidade de ventilação mecânica se correlacionava com a extensão do envolvimento pulmonar. RESULTADOS: A faixa etária dos pacientes com COVID-19 (54,8 anos) foi maior do que a dos pacientes sem a doença (45,5 anos) (p = 0,031). Opacidades em vidro fosco foram as alterações mais frequentes (88,6%; p = 0,0001). Bandas parenquimatosas (p = 0,013), ectasia brônquica (p = 0,046) e consolidações peribroncovasculares (p = 0,012) foram mais frequentes nos pacientes que necessitaram de ventilação mecânica. Pacientes com comorbidades apresentaram envolvimento parenquimatoso mais extenso (p = 0,023). A TC apresentou sensibilidade de 84,3%, especificidade de 36,7% e acurácia de 73,5% (p = 0,012). CONCLUSÃO: Os padrões de TC são úteis para o diagnóstico de COVID-19 e avaliação dos critérios de gravidade da doença. Pacientes com comorbidades estão associados a condições clínicas mais graves.

RESUMO
ABSTRACT Objective To evaluate the role of chest computed tomography in patients with COVID-19 who presented initial negative result in reverse transcriptase-polymerase chain reaction (RT-PCR). Methods A single-center, retrospective study that evaluated 39 patients with negative RT-PCR for COVID-19, who underwent chest computed tomography and had a final clinical or serological diagnosis of COVID-19. The visual tomographic classification was evaluated according to the Consensus of the Radiological Society of North America and software developed with artificial intelligence for automatic detection of findings and chance estimation of COVID-19. Results In the visual tomographic analysis, only one of them (3%) presented computed tomography classified as negative, 69% were classified as typical and 28% as indeterminate. In the evaluation using the software, only four (about 10%) had a probability of COVID-19 <25%. Conclusion Computed tomography can play an important role in management of suspected cases of COVID-19 with initial negative results in RT-PCR, especially considering those patients outside the ideal window for sample collection for RT-PCR.
RESUMO Objetivo Avaliar o papel da tomografia computadorizada de tórax em pacientes com COVID-19 que apresentaram reação em cadeia da polimerase via transcriptase reversa (RT-PCR) inicial falsamente negativa. Métodos Estudo retrospectivo de centro único que avaliou 39 pacientes com RT-PCR negativa para COVID-19, submetidos à tomografia computadorizada de tórax e que tiveram diagnóstico final clínico ou serológico de COVID-19. A classificação tomográfica visual foi avaliada de acordo com o Consenso da Radiological Society of North America e o software desenvolvido com inteligência artificial para detecção automática de achados e estimativa de probabilidade de COVID-19. Resultados Na análise tomográfica visual, somente um deles (3%) apresentou tomografia computadorizada classificada como tendo resultado negativo, 69% foram classificados como típicos e 28% como indeterminados. Na avaliação com uso de software, somente quatro (cerca de 10%) tiveram probabilidade de COVID-19 <25%. Conclusão A tomografia computadorizada pode desempenhar papel importante no manejo de casos suspeitos de COVID-19 com RT-PCR inicialmente negativa, principalmente levando-se em consideração os pacientes que estão fora da janela ideal para coleta de amostra para RT-PCR.

ABSTRACT OBJECTIVE To identify demographic and clinical characteristics of adult patients hospitalized in the Brazilian Unified Health System (SUS) due to viral pneumonia and investigate the association between some comorbidities and death during hospitalization. METHODS This retrospective cohort study was conducted with secondary data of adults admitted to SUS due to viral pneumonia between 2002 and 2015. Patient profile was characterized based on demographic and clinical variables. The association between the ten Elixhauser comorbidities and in-hospital death was investigated using Poisson regression models with robust standard errors. Results were quantified as incidence rate ratio (IRR) with 95% confidence intervals (CI), and we built five models using successive inclusion of variables blocks. RESULTS Hospital admissions for viral pneumonias decreased throughout the study period, and it was observed that 5.8% of hospitalized patients had an in-hospital death. We observed significant differences in demographic and clinical characteristics by comparing individuals who died during hospitalization with those who did not, with the occurrence of one or more comorbidities being more expressive among patients who died. Although not considered risk factors for in-hospital death, chronic pulmonary disease and congestive heart failure were the most common comorbidities. Conversely, IRR for in-hospital death increased with other neurological disorders, diabetes, cancer, obesity, and especially with HIV/AIDS. CONCLUSIONS Individuals presenting with pulmonary and cardiovascular diseases require proper attention during hospitalization, as well as those with other neurological diseases, diabetes, cancer, obesity, and especially HIV/AIDS. Understanding the influence of chronic diseases on viral infections may support the healthcare system in achieving better outcomes.

Pandemias surgem de tempos em tempos, acometem muitos países e impactam em muitas áreas além da saúde pública, desde sociais até econômicas. O surgimento desta pandemia de coronavírus na China, alerta para o fato da aproximação do homem com o meio ambiente, havendo a possibilidade de transmissão de doenças por vetores primários e intermediários ao homem. Frente a novas doenças, precisamos entender sua epidemiologia, sua patologia e cura (ou, o melhor que estiver disponível para o seu tratamento). O coronavírus surgiu como doença a partir de um mercado na China, como tantos existem mundo afora. O avanço desta pandemia mostrou que não estávamos preparados para ela, que pela primeira vez uma gripe transmitida por morcegos atingiu globalmente a saúde pública. Esta mini revisão procura mostrar um pouco do entendimento do coronavírus e do seu caminho até o epitélio pulmonar, iniciando, ali sintomas que podem ser insidiosos a até uma síndrome de angústia respiratória aguda
Pandemics arise from time to time, present im many countries and impact in many areas beyond public health, from social and economic areas. The emergence of this coronavirus pandemic in China, warns of the fact that the approximation of the man with the environment, the possibility of transmission of diseases from primary and secondary hosts to man. Facing emergence diseases, we must understand the epidemiology, the pathology and the treatment of this (or the best available for your treatment). The coronavirus emerged as a disease in a market in China, like so many exist worldwide. The advance of this pandemic shows us that we are not prepared for it, that for the first time a strain of influenza swept across all humanity and their health public systemn. This mini review seeks to show a little understanding of the coronavirus and your way to the pulmonary epithelium, starting symptoms that can be insidious to even an acute respiratory distress syndrome.

OBJECTIVE: To investigate the relationship between lung lesion burden (LLB) found on chest computed tomography (CT) and 30-day mortality in hospitalized patients with high clinical suspicion of coronavirus disease 2019 (COVID-19), accounting for tomographic dynamic changes. METHODS: Patients hospitalized with high clinical suspicion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in a dedicated and reference hospital for COVID-19, having undergone at least one RT-PCR test, regardless of the result, and with one CT compatible with COVID-19, were retrospectively studied. Clinical and laboratory data upon admission were assessed, and LLB found on CT was semi-quantitatively evaluated through visual analysis. The primary outcome was 30-day mortality after admission. Secondary outcomes, including the intensive care unit (ICU) admission, mechanical ventilation used, and length of stay (LOS), were assessed. RESULTS: A total of 457 patients with a mean age of 57±15 years were included. Among these, 58% presented with positive RT-PCR result for COVID-19. The median time from symptom onset to RT-PCR was 8 days [interquartile range 6-11 days]. An initial LLB of ≥50% using CT was found in 201 patients (44%), which was associated with an increased crude at 30-day mortality (31% vs. 15% in patients with LLB of <50%, p<0.001). An LLB of ≥50% was also associated with an increase in the ICU admission, the need for mechanical ventilation, and a prolonged LOS after adjusting for baseline covariates and accounting for the CT findings as a time-varying covariate; hence, patients with an LLB of ≥50% remained at a higher risk at 30-day mortality (adjusted hazard ratio 2.17, 95% confidence interval 1.47-3.18, p<0.001). CONCLUSION: Even after accounting for dynamic CT changes in patients with both clinical and imaging findings consistent with COVID-19, an LLB of ≥50% might be associated with a higher risk of mortality.

Resumen: La enfermedad por coronavirus 2019 (COVID-19) causada por el virus SARS-CoV-2 es una nueva enfermedad caracterizada por generar daño pulmonar y compromiso de múltiples tejidos y órganos de todo el cuerpo. Algunos de los pacientes que presentan la infección ameritan manejo intrahospitalario con soporte de O2 y medidas adicionales que pueden incluir inmovilización prolongada en UCI. Los pacientes que presentan cuadros moderados o severos y sobreviven a la enfermedad pueden presentar deterioro y disfunciones a largo plazo, incluyendo fibrosis pulmonar, miocardiopatía, lesión renal, hepática, de nervio periférico y todas las complicaciones derivadas de hospitalizaciones en UCI. Se considera que la intervención en rehabilitación pulmonar reviste gran importancia, especialmente en la etapa de recuperación, y debe realizarse, principalmente, con los objetivos de mejorar la disnea, la debilidad muscular severa y la fatiga, a fin de promover la independencia funcional y aumentar la calidad de vida, de manera que se disminuye así la ansiedad y la depresión.
Abstract: Coronavirus disease 2019 (COVID-19) caused by SARS-COV-2 virus is a new disease characterized by generating lung damage and compromising multiple tissues and organs throughout the body. Some of the patients with the infection should need intrahospital management with O2 support and additional measures that may include prolonged ICU immobilization. Patients who have moderate or severe conditions and survive the disease, could experience long-term impairment and dysfunction, including pulmonary fibrosis, cardiomyopathy, renal, hepatic and peripheral nerve injury, and all complications arising from hospitalizations in the ICU. It is considered that intervention in pulmonary rehabilitation is particularly important, especially at the recovery stage, and should be performed mainly with the objectives of improving: dyspnea, severe muscle weakness and fatigue, in order to promote functional independence and increase quality of life, so that anxiety and depression are diminished.
Resumo: A doença por coronavírus (COVID-19), causada pelo vírus SARS-COV-2, é uma nova doença caracterizada por gerar dano pulmonar e comprometimento de múltiplos tecidos e órgãos de todo o corpo. Alguns dos pacientes que apresentam a infecção merecem atendimento intra-hospitalar com suporte de O2 e medidas extraordinárias que podem incluir imobilização prolongada na UTI. Os pacientes que apresentam quadros moderados ou graves e sobrevivem à doença podem apresentar deterioração e disfunções em longo prazo, incluindo fibrose pulmonar, miocardiopatia, lesão renal, hepática, de nervo periférico e todas as complicações derivadas de internações em UTI. Considera-se que a intervenção em reabilitação pulmonar ganha grande importância, especialmente na etapa de recuperação, e deve realizar-se principalmente com o objetivo de melhorar a dispneia, a debilidade muscular grave e a fatiga, a fim de promover a independência funcional e aumentar a qualidade de vida, para que assim a ansiedade e a depressão diminuam.

La tendencia es ascendente. Conclusiones: el comportamiento de las infecciones respiratorias agudas se encontró dentro de los parámetros esperados, excepto que a partir de la semana once existió un incremento de las atenciones médicas, lo cual pudiera relacionarse con las pesquisas y acciones de vigilancia.
ABSTRACT Foundation: due to the current pandemic of COVID 19, it is important to know the categorizing essentialities of acute respiratory infections in general for future studies in which COVID 19 will constitute a category of the taxonomy of those to be taken into account. Objective: to characterize acute respiratory infections in the Cienfuegos province from January 1 to March 31, 2020. Methods: the population studied was the population of the Cienfuegos province. The main study variables considered were: age groups, municipalities of residence, demand for medical consultations, statistical weeks, rates temporal variation, their trend, severity of clinical evolution, admissions and deaths from severe respiratory infections, outbreaks and epidemiological surveillance. Statistical methods and techniques used were, from descriptive statistics: absolute and relative frequencies, means, rates, increases and decreases in rates, the endemic corridor and its trend. Results: the characterizing essentialities were: its highest incidence in children under five years of age and adults 60 years and over; the leading cause of death was from community-acquired pneumonia; the identified circulating viruses were respiratory syncytial, parainfluenza, unsubtyped influenza A, and coronavirus. The trend is upward. Conclusions: the behavior of acute respiratory infections was within the expected parameters, except that from week eleven there was an increase in medical care, which could be related to the inquiring and surveillance actions.
RESUMO
In December 2019, a striking appearance of new cases of viral pneumonia in Wuhan led to the detection of a novel coronavirus (SARS-CoV2). By analyzing patients with severe manifestations, it became apparent that 20 to 35% of patients who died had preexisting cardiovascular disease. This finding warrants the important need to discuss the influence of SARS-CoV2 infection on the cardiovascular system and hemodynamics in the context of clinical management, particularly during mechanical ventilation. The SARS-CoV2 enters human cells through the spike protein binding to angiotensin-converting enzyme 2 (ACE2), which is important to cardiovascular modulation and endothelial signaling. As ACE2 is highly expressed in lung tissue, patients have been progressing to acute respiratory injury at an alarming frequency during the Coronavirus Disease (COVID-19) pandemic. Moreover, COVID-19 leads to high D-dimer levels and prothrombin time, which indicates a substantial coagulation disorder. It seems that an overwhelming inflammatory and thrombogenic condition is responsible for a mismatching of ventilation and perfusion, with a somewhat near-normal static lung compliance, which describes two types of pulmonary conditions. As such, positive pressure during invasive mechanical ventilation (IMV) must be applied with caution. The authors of this review appeal to the necessity of paying closer attention to assess microhemodynamic repercussion, by monitoring central venous oxygen saturation during strategies of IMV. It is well known that a severe respiratory infection and a scattered inflammatory process can cause non-ischemic myocardial injury, including progression to myocarditis. Early strategies that guide clinical decisions can be lifesaving and prevent extended myocardial damage. Moreover, cardiopulmonary failure refractory to standard treatment may necessitate the use of extreme therapeutic strategies, such as extracorporeal membrane oxygenation.

La enfermedad por coronavirus originada en el año 2019 (COVID-19), se ha diseminado rápidamente en todo el mundo produciendo estragos en el sistema de salud y la sociedad. Se reporta el caso de un varón de 26 años de edad con antecedentes de asma y obesidad, que retornó de EE.UU y acudió a emergencia con síntomas respiratorios, hipoxemia e infiltrado intersticial en la radiografía de tórax, se decide internamiento en sala de aislamiento, la prueba molecular RT-PCR de hisopado nasofaríngeo resultó negativa, por lo que fue traslado a una sala de emergencia común. El manejo inicial fue conservador, sin embargo el paciente evolucionó desfavorablemente requiriendo soporte ventilatorio, pero fallece al quinto día de internamiento. Se recibió un segundo resultado positivo para SARS-CoV-2 al día siguiente de fallecido el paciente, siendo una de las primeras víctimas jóvenes en el Perú.
The coronavirus disease originated in the year 2019 (COVID-19), has spread rapidly throughout the world, wreaking havoc on the health system and society. We report the case of a 26-year-old man with a history of asthma and obesity, who returned from the US and went to the emergency room with respiratory symptoms, hypoxemia and interstitial infiltrate on chest radiography, he was admitted to the isolation room The nasopharyngeal swab RT-PCR molecular test was negative, so he was transferred to a common emergency room. Initial management was conservative, however the patient evolved unfavorably requiring ventilatory support, but died on the fifth day of hospitalization. A second positive result for SARS-CoV-2 was received the day after the patient died, being one of the first young victims in Peru.

A rapid systematic review was carried out to evaluate the current evidence related to the presence of SARS-CoV-2 in breast milk from pregnant women with COVID-19. Eight studies analyzing the presence of SARS-CoV-2 RNA in the breast milk of 24 pregnant women with COVID-19 during the third trimester of pregnancy were found. All patients had fever and/or symptoms of acute respiratory illness and chest computed tomography images indicative of COVID-19 pneumonia. Most pregnant women had cesarean delivery (91.7%) and two neonates had low birthweight (< 2 500 g). Biological samples collected immediately after birth from upper respiratory tract (throat or nasopharyngeal) of neonates and placental tissues showed negative results for the presence SARS-CoV-2 by RT-PCR test. No breast milk samples were positive for SARS-CoV-2 and, to date, there is no evidence on the presence of SARS-CoV-2 in breast milk of pregnant women with COVID-19. However, data are still limited and breastfeeding of women with COVID-19 remains a controversial issue. There are no restrictions on the use of milk from a human breast milk bank.
Se llevó a cabo una revisión sistemática rápida para evaluar la evidencia disponible sobre la presencia de SARS-CoV-2 en la leche materna de mujeres embarazadas afectadas con COVID-19. Se encontraron ocho estudios que analizaron la presencia de ARN de SARS-CoV-2 en la leche materna de 24 mujeres embarazadas con COVID-19 durante el tercer trimestre del embarazo. Todas las pacientes tenían fiebre o síntomas de enfermedad respiratoria aguda e imágenes de tomografía computarizada de tórax indicativas de neumonía por COVID-19. La mayoría de las mujeres embarazadas (91,7%) tuvieron un parto por cesárea y dos neonatos presentaron bajo peso al nacer (< 2 500 g). Las muestras biológicas recogidas inmediatamente después del parto de las vías respiratorias superiores (faringe o nasofaringe) de los neonatos y los tejidos placentarios mostraron resultados negativos para SARS-CoV-2 mediante RT-PCR. Ninguna muestra de leche materna fue positiva para SARS-CoV-2 y, hasta la fecha, no hay evidencia de la presencia de SARS-CoV-2 en la leche materna de las mujeres embarazadas con COVID-19. Sin embargo, los datos disponibles todavía son limitados y la lactancia materna en las mujeres con COVID-19 sigue siendo un tema controvertido. No hay restricciones para el uso de leche materna de banco.
Foi realizada uma revisão sistemática rápida para avaliar as evidências atuais relacionadas à presença da SARS-CoV-2 no leite materno de mulheres grávidas com COVID-19. Foram encontrados oito estudos analisando a presença de RNA do SARS-CoV-2 no leite materno de 24 gestantes com COVID-19 durante o terceiro trimestre de gravidez. Todas as pacientes apresentavam febre ou sintomas de doença respiratória aguda e imagens de tomografia computadorizada do tórax indicativas de pneumonia pela COVID-19. A maioria das gestantes teve parto cesáreo (91,7%) e dois recém-nascidos tiveram baixo peso ao nascer (< 2 500 g). As amostras biológicas coletadas imediatamente após o nascimento do trato respiratório superior (faringe ou nasofaringe) de neonatos e tecidos placentários apresentaram resultados negativos para a presença do SARS-CoV-2 pelo teste RT-PCR. Nenhuma amostra de leite materno foi positiva para o SARS-CoV-2 e, até à data, não há evidências da presença do SARS-CoV-2 no leite materno de mulheres grávidas com COVID-19. No entanto, os dados ainda são limitados e a amamentação de mulheres com COVID-19 continua a ser uma questão controversa. Não há restrições ao uso de leite de um banco de leite materno humano.

RESUMO
The World Health Organization (WHO) was informed on December 2019 about a coronavirus pneumonia outbreak in Wuhan, Hubei province (China). Subsequently, on March 12, 2020, 125,048 cases and 4,614 deaths were reported. Coronavirus is an enveloped RNA virus, from the genus Betacoronavirus, that is distributed in birds, humans, and other mammals. WHO has named the novel coronavirus disease as COVID-19. More than 80 clinical trials have been launched to test coronavirus treatment, including some drug repurposing or repositioning for COVID-19. Hence, we performed a search in March 2020 of the clinicaltrials.gov database. The eligibility criteria for the retrieved studies were: contain a clinicaltrials.gov base identifier number; describe the number of participants and the period for the study; describe the participants' clinical conditions; and utilize interventions with medicines already studied or approved for any other disease in patients infected with the novel coronavirus SARS-CoV-2 (2019-nCoV). It is essential to emphasize that this article only captured trials listed in the clinicaltrials.gov database. We identified 24 clinical trials, involving more than 20 medicines, such as human immunoglobulin, interferons, chloroquine, hydroxychloroquine, arbidol, remdesivir, favipiravir, lopinavir, ritonavir, oseltamivir, methylprednisolone, bevacizumab, and traditional Chinese medicines (TCM). Although drug repurposing has some limitations, repositioning clinical trials may represent an attractive strategy because they facilitate the discovery of new classes of medicines; they have lower costs and take less time to reach the market; and there are existing pharmaceutical supply chains for formulation and distribution.
En diciembre de 2019 fue informado a la Organización Mundial de la Salud (OMS) un brote de neumonía por coronavirus en Wuhan, provincia de Hubei, China. Al 12 de marzo de 2020, se habían notificado 125 048 casos y 4 614 muertes. El coronavirus es un virus ARN envuelto del género Betacoronavirus distribuido en aves, seres humanos y otros mamíferos. La OMS ha denominado a la nueva enfermedad por coronavirus COVID-19. Se han puesto en marcha más de 80 ensayos clínicos para evaluar un tratamiento para el coronavirus, que incluyen algunos ensayos de reposicionamiento de medicamentos para la COVID-19. En marzo de 2020 se llevó a cabo una búsqueda de los ensayos clínicos registrados en la base de datos clinicaltrials.gov. Los criterios de elegibilidad para los estudios recuperados fueron tener un número de identificación de la base de datos clinicaltrials.gov; describir el número de participantes y el período del estudio; describir las condiciones clínicas de los participantes; y emplear intervenciones con medicamentos ya estudiados o aprobados para cualquier otra enfermedad en pacientes infectados con el nuevo coronavirus SARS-CoV-2 (2019-nCoV). Es esencial destacar que este artículo solo recoge los ensayos que figuran en la base de datos clinicaltrials. gov. Se identificaron 24 ensayos clínicos relacionados con más de 20 medicamentos, como inmunoglobulina humana, interferones, cloroquina, hidroxicloroquina, arbidol, remdesivir, favipiravir, lopinavir, ritonavir, oseltamivir, metilprednisolona, bevacizumab y medicina tradicional china. Aunque el reposicionamiento de medicamentos tiene algunas limitaciones, el reposicionamiento de los ensayos clínicos puede representar una estrategia atractiva porque facilita el descubrimiento de nuevas clases de medicamentos; estos tienen costos más bajos y tardan menos en llegar al mercado; y existen cadenas de suministro farmacéutico que apoyan la formulación y la distribución.
