ABSTRACT

Em pacientes críticos o risco nutricional e a hiperglicemia associam-se ao aumento da incidência de desfechos desfavoráveis. Objetivo: Avaliar a relação do risco nutricional pelo Nutrition Risk in Critically III, versão modificada (mNUTRIC) e perfil glicêmico nos desfechos de alta, óbito e tempo de internação de pacientes críticos e verificar o impacto das ferramentas Acute Physiology and Chronic Health Disease Classification System II (APACHE II) e do Sepsis-Related Organ Failure Assessment (SOFA) nesses desfechos. Método: Estudo longitudinal prospectivo desenvolvido em Unidade de Terapia Intensiva (UTI). Foram incluídos adultos, com tempo ≥ 48 horas de internação e com registro mínimo de duas aferições glicêmicas. Excluíram-se pacientes em cuidados paliativos, readmitidos nas UTI e gestantes. O teste Exato de Fisher e Shapiro Wilk foram utilizados para avaliar as variáveis categóricas e contínuas, respectivamente. Posteriormente, utilizou-se o teste de Mann-Whitney ou t-Student não pareado. Realizou-se análise de regressão logística e linear. O nível de significância adotado foi de 5%. Resultados: Ao avaliar 35 pacientes, 45,7% apresentaram alto risco nutricional. Foi observado associação do risco nutricional com os desfechos de alta e óbito; o SOFA associou-se ao óbito e tempo de internação. O incremento de 1 ponto no escore do SOFA aumentou a chance de óbito em 83% e tempo maior de internação em 0,49 dias. O perfil glicêmico e APACHE II não se associou aos desfechos. Conclusão: o escore SOFA foi o instrumento que apresentou associações significativas com o desfecho do óbito e maior tempo de internação de pacientes críticos


In critically ill patients, nutritional risk and hyperglycemia are associated with an increased incidence of unfavorable outcomes. Objective: To evaluate the relationship of nutritional risk by the Nutrition Risk in Critically III, modified version (mNUTRIC) and glycemic profile in the outcomes of discharge, death and length of stay in critically ill patients and to verify the impact of the Acute Physiology and Chronic Health Disease Classification System II (APACHE II) and the Sepsis-Related Organ Failure Assessment (SOFA) tools on these outcomes. Method: Prospective longitudinal study developed in an Intensive Care Unit (ICU). Adults were included, with ≥ 48 hours of hospitalization and with a minimum record of two blood glucose measurements. Patients in palliative care, readmitted to ICU and pregnant women were excluded. Fisher's Exact test and Shapiro Wilk test were used to evaluate categorical and continuous variables, respectively. Subsequently, the Mann-Whitney or unpaired t-Student test was used. Logistic and linear regression analysis was performed. The significance level adopted was 5%. Results: When evaluating 35 patients, 45.7% were at high nutritional risk. An association was observed between nutritional risk and discharge and death outcomes; SOFA was associated with death and length of hospital stay. The increment of 1 point in the SOFA score increased the chance of death by 83% and a longer hospital stay by 0.49 days. Glycemic profile and APACHE II were not associated with outcomes. Conclusion: the SOFA score was the instrument that showed significant associations with the outcome of death and longer hospital stay in critically ill patients

ABSTRACT

RESUMO Objetivo: Avaliar o Simplified Acute Physiology Score 3 (SAPS 3) como substituto do Acute Physiology and Chronic Health Evaluation II (APACHE II) como marcador de gravidade na versão modificada do escore NUTrition RIsk in the Critically ill (mNUTRIC; sem interleucina 6), com base em uma análise de sua capacidade discriminativa para predição de mortalidade hospitalar. Métodos: Este estudo de coorte retrospectiva avaliou 1.516 pacientes adultos internados em uma unidade de terapia intensiva de um hospital geral privado entre abril de 2017 e janeiro de 2018. A avaliação de desempenho incluiu as análises Kappa de Fleiss e correlação de Pearson. A capacidade discriminativa para estimar a mortalidade hospitalar foi avaliada com a curva Característica de Operação do Receptor. Resultados: A amostra foi dividida aleatoriamente em dois terços para o desenvolvimento do modelo (n = 1.025; idade 72 [57 - 83]; 52,4% masculino) e um terço para avaliação do desempenho (n = 490; idade 72 [57 - 83]; 50,8 % masculino). A concordância com o mNUTRIC foi Kappa de 0,563 (p < 0,001), e a correlação entre os instrumentos foi correlação de Pearson de 0,804 (p < 0,001). A ferramenta mostrou bom desempenho para prever a mortalidade hospitalar (área sob a curva de 0,825 [0,787 - 0,863] p < 0,001). Conclusão: A substituição do APACHE II pelo SAPS 3 como marcador de gravidade no escore mNUTRIC mostrou bom desempenho para predizer a mortalidade hospitalar. Esses dados fornecem a primeira evidência sobre a validade da substituição do APACHE II pelo SAPS 3 no mNUTRIC como marcador de gravidade. São necessários estudos multicêntricos e análises adicionais dos parâmetros de adequação nutricional.


ABSTRACT Objective: To evaluate the substitution of Acute Physiology and Chronic Health Evaluation II (APACHE II) by Simplified Acute Physiology Score 3 (SAPS 3) as a severity marker in the modified version of the NUTrition RIsk in the Critically ill score (mNUTRIC); without interleukin 6) based on an analysis of its discriminative ability for in-hospital mortality prediction. Methods: This retrospective cohort study evaluated 1,516 adult patients admitted to an intensive care unit of a private general hospital from April 2017 to January 2018. Performance evaluation included Fleiss' Kappa and Pearson correlation analysis. The discriminative ability for estimating in-hospital mortality was assessed with the Receiver Operating Characteristic curve. Results: The sample was randomly divided into two-thirds for model development (n = 1,025; age 72 [57 - 83]; 52.4% male) and one-third for performance evaluation (n = 490; age 72 [57 - 83]; 50.8% male). The agreement with mNUTRIC was Kappa of 0.563 (p < 0.001), and the correlation between the instruments was Pearson correlation of 0.804 (p < 0.001). The tool showed good performance in predicting in-hospital mortality (area under the curve 0.825 [0.787 - 0.863] p < 0.001). Conclusion: The substitution of APACHE II by SAPS 3 as a severity marker in the mNUTRIC score showed good performance in predicting in-hospital mortality. These data provide the first evidence regarding the validity of the substitution of APACHE II by SAPS 3 in the mNUTRIC as a marker of severity. Multicentric studies and additional analyses of nutritional adequacy parameters are required.

ABSTRACT

RESUMO Objetivo: Relatar a independência funcional e o grau de comprometimento pulmonar em pacientes adultos 3 meses após a alta da unidade de terapia intensiva. Métodos: Este foi um estudo de coorte retrospectiva conduzido em uma unidade de terapia intensiva multiprofissional para pacientes adultos em um único centro. Incluíram-se pacientes admitidos à unidade de terapia intensiva entre janeiro de 2012 e dezembro de 2013 que, 3 meses mais tarde, foram submetidos à espirometria e responderam ao questionário Medida de Independência Funcional. Resultados: Os pacientes foram divididos em grupos segundo sua classificação de independência funcional e espirometria. O estudo incluiu 197 pacientes, que foram divididos entre os grupos maior dependência (n = 4), menor dependência (n = 12) e independente (n = 181). Na comparação dos três grupos com relação à classificação pela Medida de Independência Funcional, pacientes com maior dependência tinham escores Acute Physiology and Chronic Health Evaluation II e Sequential Organ Failure Assessment mais altos quando da admissão à unidade de terapia intensiva, idade mais avançada, mais dias sob ventilação mecânica e tempo mais longo de permanência na unidade de terapia intensiva e no hospital. A maioria dos pacientes apresentava comprometimento pulmonar, sendo o padrão obstrutivo o mais frequentemente observado. Na comparação da independência funcional com a função pulmonar, observou-se que, quanto pior a condição funcional, pior a função pulmonar, observando-se diferenças significantes em relação ao pico de fluxo expiratório (p = 0,030). Conclusão: Em sua maioria, os pacientes que retornaram ao ambulatório 3 meses após a alta tinham boa condição funcional, porém apresentavam comprometimento pulmonar relacionado com o grau de dependência funcional.


ABSTRACT Objective: To relate functional independence to the degree of pulmonary impairment in adult patients 3 months after discharge from the intensive care unit. Methods: This was a retrospective cohort study conducted in one adult intensive care unit and a multi-professional post-intensive care unit outpatient clinic of a single center. Patients admitted to the intensive care unit from January 2012 to December 2013 who underwent (3 months later) spirometry and answered the Functional Independence Measure Questionnaire were included. Results: Patients were divided into groups according to the classification of functional independence and spirometry. The study included 197 patients who were divided into greater dependence (n = 4), lower dependence (n = 12) and independent (n = 181) groups. Comparing the three groups, regarding the classification of the Functional Independence Measure, patients with greater dependence had higher Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment values at intensive care unit admission with more advanced age, more days on mechanical ventilation, and longer stay in the intensive care unit and hospital. The majority of patients presented with pulmonary impairment, which was the obstructive pattern observed most frequently. When comparing functional independence with pulmonary function, it was observed that the lower the functional status, the worse the pulmonary function, with a significant difference being observed in peak expiratory flow (p = 0.030). Conclusion: The majority of patients who returned to the outpatient clinic 3 months after discharge had good functional status but did present with pulmonary impairment, which is related to the degree of functional dependence.

Objetivo: Describir el comportamiento de 20 casos positivos a SARS CoV-2 en una unidad de cuidados intensivos. Métodos: Estudio observacional, descriptivo, de cohorte y prospectivo, aplicado entre marzo y julio del 2020, en la Unidad de Cuidados Intensivos del Hospital Clínico-Quirúrgico Dr. Salvador Allende, La Habana, Cuba. La población estuvo conformada por la totalidad de pacientes ingresados positivos a SARS CoV-2 (n= 20). Resultados: La edad promedio fue de 64,35 ± 15,21 años. El sexo masculino sobresalió. La estadía media fue 10,05 ± 5,5 días. El APACHE II medio fue de 16,6 ± 8,9. Los síntomas predominantes fueron la fiebre (55 por ciento), la tos (25 por ciento) y la disnea (20 por ciento). Conclusiones: La mortalidad en pacientes con COVID-19 se asoció con la edad, con el aumento de la estadía en Unidad de Cuidados Intensivos, elevados puntajes APACHE II, disminución de los valores de eritrosedimentación y del recuento linfocitario. La hipertensión fue el antecedente patológico más recurrente(AU)


Introduction: At the end of 2019 a new coronavirus caused an epidemic of acute respiratory disease in Wuhan, China. The World Health Organization called this condition "coronavirus disease 2019" and declared it pandemic on 11 March 2020. On that same date the first three COVID-19 cases were diagnosed in Cuba. Objective: Describe the behavior of 20 SARS-CoV-2 positive cases in an intensive care unit. Methods: An observational descriptive prospective cohort study was conducted from March to July 2020 at the Intensive Care Unit of Dr Salvador Allende Clinical Surgical Hospital in Havana, Cuba. The study population was all the patients admitted for positive SARS-CoV-2 (n= 20). Results: Mean age was 64.35 ± 15.21 years. Male sex prevailed. Mean hospital stay was 10.05 ± 5.5 days. Mean APACHE II was 16.6 ± 8.9. The prevailing symptoms were fever (55 percent), coughing (25 percent) and dyspnea (20 percent). Conclusions: Mortality of COVID-19 patients was associated to age, a longer stay in the intensive care unit, high APACHE II scores, reduced erythrosedimentation values and lymphocyte count. Hypertension was the most common pathological antecedent(AU)

ABSTRACT

Abstract Acute pancreatitis is a rare condition in pregnancy, associated with a high mortality rate. Hypertriglyceridemia represents its second most common cause.We present the case of a 38-year-old woman in the 24th week of gestation with a history of hypertriglyceridemia and recurrent episodes of pancreatitis. She was admitted to our hospital with acute pancreatitis due to severe hypertriglyceridemia. She was stabilized and treated with fibrates. Despite her favorable clinical course, she developed a second episode of acute pancreatitis complicated by multi-organ dysfunction and pancreatic necrosis, requiring a necrosectomy. The pregnancy was ended by cesarean section, after which three plasmapheresis sessions were performed. She is currently asymptomatic with stable triglyceride levels. Acute pancreatitis due to hypertriglyceridemia represents a diagnostic and therapeutic challenge in pregnant women, associated with serious maternal and fetal complications. When primary hypertriglyceridemia is suspected, such as familial chylomicronemia syndrome, the most important objective is preventing the onset of pancreatitis.

ABSTRACT

This study aimed to investigate the value of sirtuin 1 (SIRT1) in differentiating sepsis patients from healthy controls (HCs), and its correlation with inflammation, disease severity, as well as prognosis in sepsis patients. Serum samples were collected from 180 sepsis patients and 180 age- and gender-matched HCs. The SIRT1 level in the serum samples was detected by enzyme-linked immunoassay. The clinical data of the sepsis patients were documented, and their disease severity scores and 28-day mortality rate were assessed. SIRT1 was decreased in sepsis patients compared with HCs, and the receiver operating characteristic curve (ROC) showed that SIRT1 distinguished sepsis patients from HCs (area under the curve (AUC): 0.901; 95% confidence interval (CI): 0.868-0.934). In sepsis patients, SIRT1 negatively correlated with serum creatinine (Scr), white blood cells (WBC), C-reactive protein (CRP), acute physiology, and chronic health evaluation II (APACHE II) score, and sequential organ failure assessment (SOFA) score, while it positively correlated with albumin. No correlation of SIRT1 with primary infection site or primary organism was observed. Furthermore, SIRT1 was reduced in 28-day non-survivors compared with 28-day survivors, and subsequent ROC showed that SIRT1 predicted 28-day mortality of sepsis patients (AUC: 0.725; 95% CI: 0.651-0.800), and its prognostic value was not inferior to Scr, albumin, WBC, and CRP, but was less than SOFA score and APACHE II score. In conclusion, measurement of serum SIRT1 might assist with the optimization of disease assessment, management strategies, and survival surveillance in sepsis patients.

ABSTRACT

OBJECTIVES@#Sepsis associated encephalopathy (SAE) is a common neurological complication of sepsis. Delirium is a common symtom of SAE. The pathophysiology of SAE is still unclear, but several likely mechanisms have been proposed, such as mitochondrial and endothelial dysfunction, neurotransmission disturbances, derangements of calcium homeostasis, cerebral microcirculation dysfunction, and brain hypoperfusion. Near-infrared spectroscopy (NIRS) is a non-invasive measure for regional cerebral oxygen saturation (rSO@*METHODS@#A total of 48 septic patients who admitted to the intensive care unit (ICU) of Xiangya Hospital, Central South University from August 2017 to May 2018, were retrospectively study. Septic shock was diagnosed according to the criteria of sepsis 3.0 defined by the American Association of Critical Care Medicine and the European Society of Critical Care Medicine. NIRS monitoring was performed during the first 6 hours admitted to ICU with sensors placed on the bilateral forehead of patients. The maximum (rSO@*RESULTS@#The overall 28-day mortality of septic shock patients was 47.92% (23/48), and the incidence of delirium was 18.75% (9/48). The rSO@*CONCLUSIONS@#Cerebral anoxia and hyperoxia, as well as the large fluctuation of cerebral oxygen saturation are important factors that affect the outcomes and the incidence of delirium in septic shock patients, which should be paid attention to in clinical practice. Dynamic monitoring of cerebral oxygen saturation and maintain its stability may be of great significance in patients with septic shock.

ABSTRACT

Resumen Antecedentes y objetivos: El sistema de calificación APACHE II permite predecir la mortalidad intrahospitalaria en terapia intensiva. Sin embargo, no está validado para cirugía cardíaca, ya que no posee buena capacidad diferenciadora. El objetivo es determinar el valor pronóstico de APACHE II en el postoperatorio de procedimientos cardíacos. Materiales y métodos: Se analizó en forma retrospectiva la base de cirugía cardíaca. Se incluyó a pacientes intervenidos entre 2017 y 2018, de los cuales se calculó la puntuación APACHE II. Se utilizó curva ROC para determinar el mejor valor de corte. El punto final primario fue mortalidad intrahospitalaria. Como puntos finales secundarios se evaluó la incidencia de bajo gasto cardíaco (BGC), accidente cerebrovascular (ACV), sangrado quirúrgico y necesidad de diálisis. Se realizó un modelo de regresión logístico multivariado para ajustar a las variables de interés. Resultados: Se analizó a 559 pacientes. La media del sistema de calificación APACHE II fue de 9.9 (DE 4). La prevalencia de mortalidad intrahospitalaria global fue de 6.1%. El mejor valor de corte de la calificación para predecir mortalidad fue de 12, con un área bajo la curva ROC de 0.92. Los pacientes con APACHE II ≥ 12 tuvieron significativamente mayor mortalidad, incidencia de BGC, ACV, sangrado quirúrgico y necesidad de diálisis. En un modelo multivariado, el sistema APACHE II se relacionó de modo independiente con mayor tasa de mortalidad intrahospitalaria (OR, 1.14; IC95%, 1.08-1.21; p < 0.0001). Conclusiones: El sistema de clasificación APACHE II demostró ser un predictor independiente de mortalidad intrahospitalaria en pacientes que cursan el postoperatorio de cirugía cardíaca.


Abstract Background and objectives: The APACHE II score allows predicting in-hospital mortality in patients admitted to intensive care units. However, it is not validated for patients undergoing cardiac surgery, since it does not have a good discriminatory capacity in this clinical scenario. The aim of this study is to determine prognostic value of APACHE II score in postoperative of cardiac surgery. Materials and methods: The study was performed using the cardiac surgery database. Patients undergoing surgery between 2017 and 2018, with APACHE II score calculated at the admission, were included. The ROC curve was used to determine a cut-off value The primary endpoint was in-hospital death. Secondary endpoints included low cardiac output (LCO), stroke, surgical bleeding, and dialysis requirement. A multivariable logistic regression model was developed to adjust to various variables of interest. Results: The study evaluated 559 patients undergoing cardiac surgery. The mean of APACHE II Score was 9.9 (SD 4). The prevalence of in-hospital death was 6.1%. The best prognostic cut-off value for the primary endpoint was 12, with a ROC curve of 0.92. Patients with an APACHE II score greater than or equal to 12 had significantly higher mortality, higher incidence of LCO, stroke, surgical bleeding and dialysis requirement. In a multivariate logistic regression model, the APACHE II score was independently associated with higher in-hospital death (OR, 1.14; 95CI%, 1.08-1.21; p < 0.0001). Conclusions: The APACHE II Score proved to be an independent predictor of in-hospital death in patients undergoing postoperative cardiac surgery, with a high capacity for discrimination.

ABSTRACT

INTRODUÇÃO: A avaliação do risco de morte e o tempo estimado de permanência em Unidade de Terapia Intensiva (UTI) é uma prática clínica relevante para predizer a gravidade da doença e traçar estratégias eficazes para a melhora do paciente e dos indicadores de qualidade do hospital. OBJETIVO: Avaliar a confiabilidade do escore APACHE IV como preditor de mortalidade e tempo de permanência em uma UTI do sul do estado do Tocantins. MATERIAL E MÉTODO: Pesquisa de caráter descritivo e quali-quantitativo realizada nos prontuários dos pacientes internados em uma UTI do sul do estado do Tocantins. Foram colhidas informações nos prontuários e aplicado o escore APACHE IV nos pacientes internados na UTI do sul do estado do Tocantins. no período de 24 de Outubro a 26 de Novembro de 2018. Foram excluídos os pacientes com período de internação inferior a 24 horas, que não realizaram todos os exames necessários para o APACHE IV, que foram transferidos do setor ou que não tiveram alta ou óbito ao final dessa pesquisa. Foi utilizado o coeficiente de correlação de Spearman para examinar a relação entre o escore APACHE-IV e o tempo de internação na UTI e para verificar a acurácia do APACHE-IV para mortalidade, à curva Receiver Operator Characteristic (ROC) com uma atribuição de 'bom'> 0,80. RESULTADOS: O escore APACHE IV foi aplicado em dez pacientes, sendo que este superestimou o período de permanência dos pacientes internados na UTI em estudo, com p<0,001 e a mortalidade geral, com diferença absoluta de 20% (p= 0,447). CONCLUSÃO: Baseada neste estudo, o APACHE IV não demonstrou confiabilidade para predição de mortalidade e tempo de permanência, porém a amostra insuficiente pode ter contribuído com esta conclusão.


INTRODUCTION: The assessment of the risk of death and the estimated length of stay in the intensive care unit (ICU) is a relevant clinical practice to predict the severity of the disease and to outline effective strategies for patient improvement and hospital quality indicators. OBJECTIVE: To evaluate the reliability of the APACHE IV score as a predictor of mortality and length of stay in a ICU in the southern state of Tocantins. MATERIAL AND METHOD: This is a descriptive and qualitative research conducted in the medical records of patients hospitalized in a suppressed ICU. Information was collected from the medical records and the APACHE IV score was applied to patients hospitalized in the ICU of the SUPRIMIDO from October 24 to November 26, 2018. Patients with hospitalization less than 24 hours who did not undergo all necessary examinations were excluded. for APACHE IV, who were transferred from the sector or who were not discharged or died at the end of this survey. Spearman's correlation coefficient was used to examine the relationship between the APACHE-IV score and ICU length of stay and to verify the accuracy of APACHE-IV for mortality, to the Receiver Operator Characteristic (ROC) curve with an assignment of ' good '> 0.80. RESULTS: The APACHE IV score was applied to ten patients, which overestimated the length of stay of ICU patients, with p <0.001 and overall mortality, with an absolute difference of 20%. (p = 0.447). CONCLUSION: Based on this study, APACHE IV did not show reliability for predicting mortality and length of stay, but the insufficient sample may have contributed to this conclusion.

ABSTRACT

ABSTRACT Objective: To propose a preliminary artificial intelligence model, based on artificial neural networks, for predicting the risk of nosocomial infection at intensive care units. Methods: An artificial neural network is designed that employs supervised learning. The generation of the datasets was based on data derived from the Japanese Nosocomial Infection Surveillance system. It is studied how the Java Neural Network Simulator learns to categorize these patients to predict their risk of nosocomial infection. The simulations are performed with several backpropagation learning algorithms and with several groups of parameters, comparing their results through the sum of the squared errors and mean errors per pattern. Results: The backpropagation with momentum algorithm showed better performance than the backpropagation algorithm. The performance improved with the xor. README file parameter values compared to the default parameters. There were no failures in the categorization of the patients into their risk of nosocomial infection. Conclusion: While this model is still based on a synthetic dataset, the excellent performance observed with a small number of patterns suggests that using higher numbers of variables and network layers to analyze larger volumes of data can create powerful artificial neural networks, potentially capable of precisely anticipating nosocomial infection at intensive care units. Using a real database during the simulations has the potential to realize the predictive ability of this model.


RESUMO Objetivo: Propor um modelo preliminar de inteligência artificial, baseado em redes neurais artificiais, para previsão do risco de infecção hospitalar em unidades de cuidado intensivo. Métodos: Foi usada uma rede neural artificial, que utiliza aprendizagem supervisionada. A geração dos conjuntos de dados baseia-se em dados derivados do sistema Japanese Nosocomial Infection Surveillance . Estudamos como o Java Neural Network Simulator aprende a categorizar esses pacientes para prever o respectivo risco de infecção hospitalar. As simulações são realizadas com diferentes algoritmos de aprendizagem por retropropagação e diversos grupos de parâmetros, comparando-se os resultados com base na soma dos erros quadráticos e erros médios por padrão. Resultados: O algoritmo de retropropagação com momentum mostrou desempenho superior ao do algoritmo de retropropagação. O desempenho foi melhor com os valores de parâmetros do arquivo xor. README em comparação aos parâmetros default . Não houve falhas na categorização de pacientes quanto ao respectivo risco de infecção hospitalar. Conclusão: Embora esse modelo se baseie em um conjunto de dados sintéticos, o excelente desempenho observado com um pequeno número de padrões sugere que o uso de números maiores de variáveis e camadas de rede para analisar volumes maiores de dados pode criar redes neurais artificiais poderosas, possivelmente capazes de prever com precisão o risco de infecção hospitalar em unidades de cuidado intensivo. O uso de um banco de dados real durante as simulações torna possível a realização da capacidade preditiva desse modelo.

ABSTRACT

RELEVANCIA: La pandemia por COVID-19 (Coronavirus Disease-2019) se origina en diciembre de 2019. En Chile, a la fecha se han reportado 13.037 fallecidos con un enorme costo y esfuerzo asistencial, siendo limitada aun la evidencia en Chile acerca de esta enfermedad. OBJETIVOS: Describir el perfil clínico y ventilatorio de los pacientes con COVID-19 que requirieron manejo en la Unidad de Cuidados Intensivos en un Hospital Terciario de la Región Metropolitana. MÉTODOS: Estudio descriptivo, observacional y retrospectivo. Se extrajeron los datos de 64 pacientes ingresados entre el 24 de Marzo y el 15 de Mayo de 2020 en la UCI del Hospital Ramón Barros Luco Trudeau en el Sector Sur de la Región Metropolitana. Los resultados primarios en el estudio fueron Mortalidad en UCI, Mortalidad Intrahospitalaria y Mortalidad a 28 días. RESULTADOS: La mortalidad en UCI fue del 20%, existiendo una asociación entre Hipertensión Arterial y Enfermedad más Grave. La obesidad se asoció con mayores días UCI. En cuanto al soporte ventilatorio, 75% de los pacientes requirió apoyo con VMI al ingreso. Existe un perfil de mejor Compliance pulmonar y bajo potencial de reclutamiento durante la primera semana. Sin embargo, entre el 7mo. y 14vo día de enfermedad existe una rápida progresión hacia menor compliance pulmonar en cierto grupo de pacientes. CONCLUSIONES: Los casos más graves de COVID-19 se dan en pacientes de avanzada edad, hipertensos y obesos, con un aumento significativo en mortalidad cuando asociaron enfermedad renal crónica sobre todo en hemodiálisis. La progresión hacia deterioros severos de la elastancia pulmonar probablemente constituyen el signo ominoso de la enfermedad.

ABSTRACT

RESUMEN: La UTI de Temuco es el único centro que recibe pacientes críticos en toda la Novena Región, que tiene un alto número de población mapuche y el mayor índice de pobreza de Chile. Desde 2017 Temuco cuenta con una nueva Unidad de Pacientes Críticos. Queríamos mostrar nuestra realidad de enero a diciembre de 2018. MÉTODO: Se revisaron y analizaron los egresos del período de un año descrito: edad, sexo, etnicidad, procedencia, diagnóstico de ingreso, Apache II, comorbilidad, días de hospitalización, ventilación mecánica y mortalidad. RESULTADOS: de 683 altas en el período de estudio, se obtuvieron 500 (73,3%) expedientes clínicos con datos suficientes para revisión: 54,2% hombres. Edad media 57,8 (15-92), 14,4% etnia mapuche. El 49,4% de los pacientes procedía de cirugía, el 26,4% de Urgencias y el 13,8% de UTI. Los diagnósticos de ingreso fueron, 36% neurológico, 20% digestivo, 18% respiratorio. El Apache II de admisiones fue de 16,27 (0-52). Los días de hospitalización fueron 9,7. El 92% de los ingresos fueron pacientes que requirieron ventilación mecánica. CONCLUSIONES: Somos una unidad de alta complejidad, en parte, por la complejidad de las cirugías que aquí se realizan, lo que requiere estancia en UCI posquirúrgica.

ABSTRACT

INTRODUCTION@#Singapore was one of the first countries affected by the coronavirus disease 2019 (COVID-19) pandemic but has been able to prevent its healthcare system and intensive care units (ICU) from being overwhelmed. We describe the clinical features, management and outcomes of COVID-19 patients with respiratory failure admitted to our ICU.@*MATERIALS AND METHODS@#A case series of COVID-19 patients admitted to our ICU for respiratory failure from 7 February, with data censoring at 30 June 2020, was performed from a review of medical records.@*RESULTS@#Twenty-two COVID-19 patients were admitted to our ICU for respiratory failure. The median age was 54.5 years (IQR 30-45.5), 72.7% were male and had at least one comorbidity. The Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were 2.5 (IQR 1.25-7) and 10 (8.25-12) respectively. Thirteen patients required invasive mechanical ventilation (IMV) and had a median PaO2/FiO2 ratio of 194 mmHg (IQR 173-213) after intubation. The 28-day survival was 100%, with 2 patients demising subsequently. The overall ICU mortality rate was 9.1% at the time of data censoring. In IMV survivors, length of IMV and ICU stay were 11 days (IQR 9-17.75) and 16 days (IQR 12-32) respectively.@*CONCLUSION@#Low COVID-19 ICU mortality was observed in our "pandemic-ready" ICU. This was achieved by having adequate surge capacity to facilitate early ICU admission and IMV, lung protective ventilation, and slow weaning. Being able to maintain clinical standards and evidence-based practices without having to resort to rationing contributed to better outcomes.

ABSTRACT

OBJECTIVE@#To study the significance of the level of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in serum and bronchoalveolar lavage fluid (BALF), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Sequential Organ Failure Assessment (SOFA) score in evaluating the conditions and prognosis of children with severe pneumonia.@*METHODS@#A total of 76 children with severe pneumonia who were admitted from August 2017 to October 2019 were enrolled as the severe pneumonia group. According to the treatment outcome, they were divided into a non-response group with 34 children and a response group with 42 children. Ninety-four children with common pneumonia who were admitted during the same period of time were enrolled as the common pneumonia group. One hundred healthy children who underwent physical examination in the outpatient service during the same period of time were enrolled as the control group. The serum level of sTREM-1, APACHE II score, and SOFA score were measured for each group, and the level of sTREM-1 in BALF was measured for children with severe pneumonia. The correlation of the above indices with the severity and prognosis of severe pneumonia in children was analyzed.@*RESULTS@#The severe pneumonia group had significantly higher serum sTREM-1 level, APACHEII score, and SOFA score than the common pneumonia group and the control group (P0.05).@*CONCLUSIONS@#The level of sTREM-1 in serum and BALF and SOFA score can be used to evaluate the severity and prognosis of severe pneumonia in children.

ABSTRACT

Background: Trauma is the main cause of death among people aged 5 to 44 years. Aim: To describe features, treatment and evolution of trauma patients admitted to an emergency room. Material and Methods: Adult patients admitted in the emergency department of a public hospital due to severe trauma were studied and followed during their hospital stay. Results: We included 114 patients aged 40 ± 17 years (78%men) with an injury severity score of 21 ± 11. Trauma was penetrating in 43%. Traumatic brain injury (TBI) was the most common diagnosis in 46%. In the emergency room, 8% had hypotension, 5% required vasopressors and 23% required mechanical ventilation. The initial lactate was 3.6 ± 2.9 mmol/L. Sixty-five patients (57%) required emergency surgery. The intraoperative lactate was 3 ± 1.7 mmol/L and 20% required vasopressors. Sixty-four patients (56%) were admitted to the ICU, with APACHEII and SOFA scores of 16 ± 8 and 5 ± 3, respectively. ICU lactate was 3.2±1.5 mmol/L. In the ICU 40% required vasopressors and 63% mechanical ventilation. Thirty two percent had coagulopathy, 43% received transfusions and 10% required massive transfusions. The hospital stay was 13 (6-32) days, being significantly longer in patients with TBI. ICU and hospital mortalities were 12.5 and 18.4% respectively. The only predictor for mortality was the APACHEII score (Hazard Ratio 1.18, 95% confidence intervals 1.03-1.36). Conclusions: APACHE score was a predictor of mortality in this group of patients.

ABSTRACT

ABSTRACT BACKGROUND: Acute pancreatitis is a common disorder in medical practice. In recent times, management has changed drastically with majority of decisions like intravenous antibiotics, negative suction with Ryle's tube and surgical interventions like necrosectomy etc based on severity of the disease. There are different scores in use to assess severity of disease but the relative efficacy has remained a debatable subject. OBJECTIVE: The present study was thus done to investigate the predictive accuracy of different scoring systems in acute pancreatitis. METHODS: Fifty patients of acute pancreatitis admitted in medicine ward of Pt. B.D. Sharma PGIMS, Rohtak, India, were taken for study after fulfilling eligibility criteria. These patients were investigated at admission and followed up prospectively. The severity of pancreatitis was classified for each of these patients as per Revised Atlanta System of Classification. Commonly used scoring systems pertaining to acute pancreatitis, viz, BISAP, Ranson, APACHE II and modified computed tomography severity index (CTSI) were calculated. Subsequently these scores were then correlated with severity, presence of organ failure, occurrence of local complications and final outcome of the patients. RESULTS: Out of 50 patients, etiology was chronic alcohol intake in all but one with idiopathic pancreatitis. The mean age of the study population was 42.06±13.27 years. 32% of these patients had pancreatic necrosis, 40% had peripancreatic collections. 56% of them had mild acute pancreatitis, 24% had moderately severe acute pancreatitis, while 20% had severe acute pancreatitis. APACHE II had the highest accuracy in predicting severity, organ failure and fatal outcomes. As far as these parameters were concerned, the negative predictive values of BISAP score were also considerable. Modified CTSI score was accurate in predicting local complications but had limited accuracy in other predictions. CONCLUSION: APACHE II emerged as most reliable scoring system followed by BISAP and Ranson in management of the patients with acute pancreatitis. But in constraints of time and resources, even BISAP score with its significant negative predictive values served as a valuable tool for assessing and managing these patients.


RESUMO CONTEXTO: A pancreatite aguda é uma desordem comum na prática médica. Nos últimos tempos, sua gestão mudou drasticamente com a maioria das decisões tomadas baseadas na gravidade da doença, como administração de antibióticos intravenosos, sucção negativa com o tubo de Ryle ou intervenções cirúrgicas como necrosectomia, etc. Há diferentes escores em uso para avaliar a gravidade da doença, mas a eficácia relativa manteve-se um assunto discutível. OBJETIVO: O presente estudo foi assim realizado para investigar a acurácia preditiva de diferentes sistemas de pontuação na pancreatite aguda. MÉTODOS: Foram selecionados 50 pacientes com pancreatite aguda admitidos na enfermaria de medicina de Pt. B.D. Sharma PGIMS, Rohtak, Índia, e foram considerados para estudo após o cumprimento dos critérios de elegibilidade. Estes pacientes foram investigados na admissão e seguidos prospectivamente. A severidade da pancreatitie foi classificada para cada um destes pacientes pelo sistema de classificação Atlanta revisado. Os sistemas de pontuação comumente usados pertencentes à pancreatite aguda, ou seja, BISAP, Ranson, APACHE II e CTSI modificado foram calculados. Posteriormente, esses escores foram correlacionados com a severidade, presença de falência de órgãos, ocorrência de complicações locais e desfecho final dos pacientes. RESULTADOS: Dos 50 pacientes, a ingestão crônica de álcool foi a etiologia em todos, exceto em um com pancreatite idiopática. A média de idade da população estudada foi de 42,6±13,27 anos. Destes pacientes, 32% apresentavam necrose pancreática, 40% apresentavam coleções peripancreáticas, 56% apresentavam pancreatite aguda leve, 24% apresentavam pancreatite aguda moderadamente grave, enquanto 20% apresentavam pancreatite aguda grave. O APACHE II teve maior precisão em prever a severidade, a falha do órgão e resultados fatais. No que diz respeito a esses parâmetros, os valores preditivos negativos do escore BISAP também foram consideráveis. A contagem modificada de CTSI foi exata em prever complicações locais, mas teve a exatidão limitada em outras predições. CONCLUSÃO: O APACHE II emergiu como o sistema de pontuação mais confiável seguido por BISAP e Ranson na gestão dos pacientes com pancreatite aguda. Mas em condicionantes do tempo e dos recursos, mesmo a Pontuação do BISAP com seus valores preditivos negativos significativos, serviu como uma ferramenta valiosa para avaliar e administrar esses pacientes.

ABSTRACT

SUMMARY PURPOSE In this prospective observational study, we aimed to investigate the role of the maximum compressed (MC) and uncompressed (UC) thickness of the quadriceps femoris muscle (QFMT) measured by ultrasonography (USG) in the detection of nutritional risk in intensive care patients (ICPs) with different volume status. METHODS 55 patients were included. Right, left, and total ucQFMT and mcQFMT measurements were obtained by a standard USG device within the first 48 hours after ICU admission. Clinical examination and the USG device were used to determine the volume status of the patients. SOFA, APACHE II, modified NUTRIC scores, and demographic data were collected. RESULTS There was a significant difference between the nutritional risk of patients in terms of left, right, and total mcQFMT measurements (p=0.025, p=0.039; p=0.028, respectively), mechanical ventilation requirement (p=0.014), presence of infection (p=0.019), and sepsis (p=0.006). There was no significant difference between different volume statuses in terms of mcQFMT measurements. In the multi-variance analysis, mcQFMT measurements were found to be independently associated with high nutritional risk (p=0.019, Exp(B)=0.256, 95%CI=0.082-0.800 for modified NUTRIC score ≥ 5), and higher nutritional risk (p=0.009, Exp(B)=0.144, 95%CI=0.033-0.620 for modified NUTRIC score ≥ 6). a Total mcQFMT value below 1.36 cm was a predictor for higher nutritional risk with 79% sensitivity and 70% specificity (AUC=0.749, p=0.002, likelihood ratio=2.04). CONCLUSION Ultrasonographic measurement of total mcQFMT can be used as a novel nutritional risk assessment parameter in medical ICPs with different volume statuses. Thus, patients who could benefit from aggressive nutritional therapy can be easily identified in these patient groups.


RESUMO OBJETIVO Neste estudo observacional prospectivo, objetivamos investigar o papel da espessura do músculo quadríceps femoral (QFMT) comprimido (mc) e não comprimido (uc) medida pela ultrassonografia (USG) na detecção do risco nutricional em pacientes de terapia intensiva (ICPs) com status de volume diferente. MÉTODOS Cinquenta e cinco pacientes foram incluídos. As medidas direita, esquerda e total de ucQFMT e mcQFMT foram obtidas por um dispositivo USG padrão nas primeiras 48 horas após a admissão na UTI. O exame clínico e o dispositivo USG foram usados para determinar o status volumétrico dos pacientes. Sofa, Apache II, escores Nutric modificados e dados demográficos foram coletados. RESULTADOS Houve diferença significativa entre o risco nutricional dos pacientes em termos de medidas da QTFMT esquerda, direita e total (p=0,025, p=0,039; p=0,028, respectivamente), necessidade de ventilação mecânica (p=0,014), presença de infecção (p=0,019) e sepse (p=0,006). Não houve diferença significativa entre os diferentes status de volume em termos de medidas de mcQFMT. Na análise de variância múltipla, verificou-se que as medidas da FCFMT estavam independentemente associadas a alto risco nutricional (p=0,019, Exp (B)=0,256, 95%CI=0,082-0,800 para escore Nutric modificado ≥ 5) e maior risco nutricional (p=0,009, Exp (B)=0,144, 95%CI=0,033-0,620 para o escore Nutric modificado ≥ 6). O valor total de mcQFMT abaixo de 1,36 cm foi um preditor de maior risco nutricional com sensibilidade de 79% e especificidade de 70% (ASC=0,749, p=0,002, razão de verossimilhança = 2,04). CONCLUSÃO A medida ultrassonográfica do mcQFMT total pode ser usada como um novo parâmetro de avaliação de risco nutricional em ICPs médicas com diferentes status de volume. Assim, pacientes que podem se beneficiar de uma terapia nutricional agressiva podem ser facilmente identificados nesses grupos de pacientes.

ABSTRACT

Abstract Background: Liver transplantation is the only curative therapeutic modality available for individuals at end-stage liver disease. There is no reliable method of predicting the early postoperative outcome of these patients. The Acute Physiology and Chronic Health Evaluation (APACHE) is a widely used model for predicting hospital survival and benchmarking in critically ill patients. This study evaluated the calibration and discrimination of APACHE IV in the postoperative period of elective liver transplantation in the southern Brazil. Methods: This was a clinical prospective and unicentric cohort study that included 371 adult patients in the immediate postoperative period of elective liver transplantation from January 1, 2012 to December 31, 2016. Results: In this study, liver transplant patients who evolved to hospital death had a significantly higher APACHE IV score (82.7 ± 5.1 vs. 51.0 ± 15.8; p < 0.001) and higher predicted mortality (6.5% [4.4-20.2%] vs. 2.3% [1.4-3.5%]; p < 0.001). The APACHE IV score showed an adequate calibration (Hosmer-Lemeshow - H-L = 11.37; p = 0.181) and good discrimination (Receiver Operator Curve - ROC of 0.797; Confidence Interval 95% - 95% CI 0.713-0.881; p < 0.0001), although Standardized Mortality Ratio (SMR = 2.63), (95% CI 1.66-4.27; p < 0.001) underestimate mortality. Conclusions: In summary, the APACHE IV score showed an acceptable performance for predicting a hospital outcome in the postoperative period of elective liver transplant recipients.


Resumo Introdução: O transplante de fígado é a única modalidade terapêutica curativa disponível para indivíduos com doença hepática terminal. Não há método confiável de prever o resultado pós-operatório imediato desses pacientes. A Avaliação da Gravidade da Doença Crônica e Aguda com bases Fisiológicas (APACHE) é um modelo amplamente usado para prever a sobrevida hospitalar e fazer a avaliação comparativa de pacientes criticamente enfermos. Este estudo avaliou a calibração e discriminação do APACHE IV no pós-operatório de transplante hepático eletivo no sul do Brasil. Métodos: Estudo clínico prospectivo de coorte em centro único que incluiu 371 pacientes adultos no pós-operatório imediato de transplante hepático eletivo de 1 de janeiro de 2012 a 31 de dezembro de 2016. Resultados: Neste estudo, pacientes com transplante hepático que evoluíram para óbito hospitalar obtiveram escore APACHE IV significativamente maior (82,7 ± 5,1 vs. 51,0 ± 15,8; p < 0,001) e mortalidade prevista mais alta (6,5% [4,4% -20,2%] vs 2,3% [1,4% -3,5%], p < 0,001). O escore APACHE IV mostrou uma calibração adequada (Hosmer-Lemeshow - H-L = 11,37; p = 0,181) e boa discriminação (Receiver Operator Curve - ROC de 0,797; intervalo de confiança de 95% - IC 95% 0,713-0,881; p < 0,0001), embora a taxa de mortalidade padronizada (Standardized Mortality Ratio - SMR = 2,63), (IC 95% 1,66-4,27; p < 0,001) subestime a mortalidade. Conclusões: Em resumo, o escore APACHE IV mostrou um desempenho aceitável para predizer um desfecho hospitalar no período pós-operatório de receptores eletivos de transplante hepático.
