RESUMEN

Objectives: Describe the use and findings of cardiopulmonary imaging-chest X-ray (cX-ray), echocardiography (cEcho), chest CT (cCT), lung ultrasound (LUS), and/or cardiac magnetic resonance imaging (cMRI)-in COVID-19 hospitalizations in Latin America (LATAM). Background: There is a lack of information on the images used and their findings during the SARS-CoV-2 pandemic in LATAM. Methods: Multicenter, prospective, observational study of COVID-19 inpatients, conducted from March to December 2020, from 12 high-complexity centers, in nine LATAM countries. Adults (>18 years) with at least one imaging modality performed, followed from admission until discharge and/or in-hospital death, were included. Results: We studied 1,435 hospitalized patients (64% males) with a median age of 58 years classified into three regions: Mexico (Mx), 262; Central America and Caribbean (CAC), 428; and South America (SAm), 745. More frequent comorbidities were overweight/obesity, hypertension, and diabetes. During hospitalization, 58% were admitted to the ICU. The in-hospital mortality was 28%, and it was highest in Mx (37%).The most frequent images performed were cCT (61%), mostly in Mx and SAm, and cX-ray (46%), significant in CAC. The cEcho was carried out in 18%, similarly among regions, and LUS was carried out in 7%, with a higher frequently in Mx. Abnormal findings on the cX-ray were peripheral or basal infiltrates, and in cCT abnormal findings were the ground glass infiltrates, more commonly in Mx. In LUS, interstitial syndrome was the most abnormal finding, predominantly in Mx and CAC.Renal failure was the most prevalent complication (20%), predominant in Mx and SAm. Heart failure developed in 13%, predominant in Mx and CAC. Lung thromboembolism was higher in Mx while myocardial infarction was in CAC.Logistic regression showed associations of abnormal imaging findings and their severity, with comorbidities, complications, and evolution. Conclusions: The use and findings of cardiopulmonary imaging in LATAM varied between regions and had a great impact on diagnosis and prognosis.

RESUMEN

ABSTRACT Liver transplantation is the major treatment for end-stage liver disease. Postoperative care is a great challenge to reduce morbidity and mortality in patients. In this sense, management in the liver ICU allows hemodynamic management, coagulation monitoring, renal support, electrolyte disturbances, respiratory support and early weaning from mechanical ventilation and evaluation of the liver graft. Objective: The present study shows the results of the management of liver transplant patients in 20 years of experience in a transplant center in a low- to middle-income country. Materials and methods: The medical records of 273 adult patients in the ICU in the immediate postoperative liver transplant were reviewed, from March 20, 2000 to November 30, 2020, including the effect of the pandemic caused by COVID-19. Liver-kidney, retransplanted, SPLIT, and domino transplant patients were excluded. Results: The most frequent etiology for LTx was NASH (35%), the mean age was 49 years, MELD Score ranged 15 - 20 (47.5%), 21 - 30 (46%) > 30 (6.2%). ICU pre transplant stay 7%, average ICU stay: 7.8 days. APACHE average admission: 14.9 points. Weaning extubation of 91.8% patients in ICU and Fast Track in 8.2%. The most frequent respiratory complication was atelectasis 56.3%, pneumonia (31.3%); AKI 1 (60.9%), and 11.1% with hemodyalisis support (AKI3). Immunosuppression: Tacrolimus (8.9%). Post-operative ICU mortality was 6.2%. Conclusions: The management of liver transplantation in the ICU is essential to achieve optimal results in patients who present advanced liver disease and require advanced life support in the immediate postoperative period and thus optimize graft survival.

RESUMEN El trasplante de hígado es el principal tratamiento para la enfermedad hepática en etapa terminal. El cuidado postoperatorio es un gran desafío para disminuir la morbimortalidad en los pacientes. En este sentido, el manejo en la UCI hepática permite manejo hemodinámico, monitoreo de coagulación, soporte renal, alteraciones electrolíticas, soporte respiratorio y destete temprano de ventilación mecánica y evaluación del injerto hepático. Objetivo: El presente estudio muestra los resultados del manejo de pacientes trasplantados de hígado en 20 años de experiencia en un centro de trasplante en un país de ingresos bajos a medios. Materiales y métodos: Se revisaron las historias clínicas de 273 pacientes adultos en UCI en el posoperatorio inmediato de trasplante hepático, desde el 20 de marzo de 2000 hasta el 30 de noviembre de 2020, incluyendo el efecto de la pandemia provocada por el COVID-19. Se excluyeron los pacientes con trasplante de hígado-riñón, retrasplantados, SPLIT y dominó. Resultados: La etiología más frecuente para LTx fue NASH (35%), la edad promedio fue de 49 años, MELD Score varió 15 - 20 (47,5%), 21 - 30 (46%) > 30 (6,2%). Estancia pretrasplante en UCI 7%, estancia media en UCI: 7,8 días. Admisión media APACHE: 14,9 puntos. Extubación weaning del 91,8% de los pacientes en UCI y Fast Track en el 8,2%. La complicación respiratoria más frecuente fue atelectasia 56,3%, neumonía (31,3%); FRA 1 (60,9%) y 11,1% con soporte de hemodiálisis (FRA 3). Inmunosupresión: Tacrolimus (8,9%). La mortalidad postoperatoria en la UCI fue del 6,2%. Conclusiones: El manejo del trasplante hepático en UCI es fundamental para lograr resultados óptimos en pacientes que presentan enfermedad hepática avanzada y requieren soporte vital avanzado en el postoperatorio inmediato y así optimizar la supervivencia del injerto.

RESUMEN

Candida auris es un hongo emergente, con gran relevancia en corto tiempo, como problema de salud pública mundial. Se reporta por primera vez en el Perú la presencia de Candida auris en 3 pacientes adultos internados en un hospital nacional de alta complejidad en el último trimestre del año 2020, durante la pandemia COVID-19. Los pacientes fueron hospitalizados en UCI; sin embargo, solo en 2 pacientes se aisló dicho germen durante su internamiento en UCI. Los pacientes tuvieron varias comorbilidades y tiempos prolongados de hospitalización desde su admisión hasta tener el primer cultivo positivo a C. auris. Todos los pacientes adquirieron una infección nosocomial bacteriana en algún momento de su hospitalización y recibieron antibióticos de amplio espectro. Todas las cepas aisladas fueron resistentes a fluconazol. El equipo de control de infecciones del hospital reforzó las medidas de contención y el Ministerio de Salud del Perú emitió una alerta epidemiológica.

Candida auris is an emerging fungus that has gained great relevance as a global public health problem in a short time. The presence of Candida auris in 3 adult patients admitted to a national hospital of high complexity in the last quarter of 2020 in the midst of the COVID-19 pandemic is reported for the first time in Peru. The patients were hospitalized in the ICU, however, this germ was isolated in only 2 patients while they were hospitalized in the ICU. The patients had various comorbidities and long hospitalization times from admission to having their first culture positive for C. auris. All patients acquired a bacterial nosocomial infection at some point during their hospitalization and received broad-spectrum antibiotics. All isolates were resistant to fluconazole. The hospital's infection control team reinforced containment measures and the Ministry of Health of Peru issued an epidemiological alert.
