Uso de la tomografía corporal total en pacientes con heridas de arma de fuego y hemodinámicamente inestables: ¿Rompiendo paradigmas de atención inicial? / Whole-body computed tomography in hemodynamically unstable patients with gunshot wounds: A paradigm shift in trauma management?

Introducción. El objetivo del estudio fue analizar el impacto del uso de la tomografía corporal total en la evaluación de los pacientes con trauma penetrante por proyectil de arma de fuego y hemodinámicamente inestables atendidos en un centro de referencia de trauma. Métodos. Se realizó un estudio analítico, retrospectivo, con base en un subanálisis del registro de la Sociedad Panamericana de Trauma ­ Fundación Valle del Lili. Se incluyeron los pacientes con trauma penetrante por proyectil de arma de fuego atendidos entre 2018 y 2021. Se excluyeron los pacientes con trauma craneoencefálico severo, trauma leve y en condición in extremis. Resultados. Doscientos pacientes cumplieron los criterios de elegibilidad, 115 fueron estudiados con tomografía corporal total y se compararon con 85 controles. La mortalidad intrahospitalaria en el grupo de tomografía fue de 4/115 (3,5 %) vs 10/85 (12 %) en el grupo control. En el análisis multivariado se identificó que la tomografía no tenía asociación significativa con la mortalidad (aOR=0,46; IC95% 0,10-1,94). El grupo de tomografía tuvo una reducción relativa del 39 % en la frecuencia de cirugías mayores, con un efecto asociado en la disminución de la necesidad de cirugía (aOR=0,47; IC95% 0,22-0,98). Conclusiones. La tomografía corporal total fue empleada en el abordaje inicial de los pacientes con trauma penetrante por proyectil de arma de fuego y hemodinámicamente inestables. Su uso no se asoció con una mayor mortalidad, pero sí con una menor frecuencia de cirugías mayores.

Introduction. This study aims to assess the impact of whole-body computed tomography (WBCT) in the evaluation of patients with penetrating gunshot wounds (GSW) who are hemodynamically unstable and treated at a trauma referral center. Methods. An analytical, retrospective study was conducted based on a subanalysis of the Panamerican Trauma Society-FVL registry. Patients with GSW treated between 2018 and 2021 were included. Patients with severe cranioencephalic trauma, minor trauma, and those in extremis were excluded. Patients with and without WBCT were compared. The primary outcome was in-hospital mortality, and the secondary outcome was the frequency of major surgeries (thoracotomy, sternotomy, cervicotomy, and/or laparotomy) during initial care. Results. Two hundred eligible patients were included, with 115 undergoing WBCT and compared to 85 controls. In-hospital mortality in the WBCT group was 4/115 (3.5%) compared to 10/85 (12%) in the control group. Multivariate analysis showed that WBCT was not significantly associated to mortality (aOR: 0.46; 95% CI 0.10-1.94). The WBCT group had a relative reduction of 39% in the frequency of major surgeries, with an associated effect on reducing the need for surgery (aOR: 0.47; 95% CI 0.22-0.98). Conclusions. Whole-body computed tomography was employed in the initial management of patients with penetrating firearm projectile injuries and hemodynamic instability. The use of WBCT was not associated with mortality but rather with a reduction in the frequency of major surgery.

Predictors of mortality among end-stage renal disease patients with COVID-19 admitted in a Philippine Tertiary Government Hospital: A retrospective cohort study

Background and Objective@#Several studies have examined the predictors of mortality among COVID-19-infected patients; however, to date, few published studies focused on end-stage renal disease patients. The present study,therefore, aims to determine the predictors of in-hospital mortality among end-stage renal disease patients with COVID-19 admitted to a Philippine tertiary hospital. @*Methods@#The researcher utilized a retrospective cohort design. A total of 449 adult end-stage renal disease patients on renal replacement therapy diagnosed with moderate-to-severe COVID-19 and were admitted at the National Kidney and Transplant Institute from June 2020 to 2021 were included. Logistic regression analysis was used to determine the factors associated with in-hospital mortality. @*Results@#In-hospital mortality among end-stage renal disease patients with COVID-19 was 31.18% (95% CI: 26.92- 35.69%). Older age (OR=1.03), male sex (OR=0.56), diabetes mellitus (OR=1.80), coronary artery disease (OR=1.71), encephalopathy (OR=7.58), and intubation (OR=30.78) were associated with in-hospital mortality. @*Conclusion@#Patients with ESRD and COVID-19 showed a high in-hospital mortality rate. Older age, diabetes mellitus, coronary artery disease, encephalopathy, and intubation increased the odds of mortality. Meanwhile, males had lower odds of mortality than females.

Early vs. Standard Loop Ileostomy Closure: An Unmatched Case-Control Study / Cierre Temprano vs Estándar de Ileostomía en Asa. Estudio de Casos y Controles no Emparejado

SUMMARY: Early closure of a loop ileostomy (ECI) is a relatively new practice, for which there is insufficient evidence regarding its effectiveness in relation to closure at conventional times. The aim of this study was to report postoperative complications (POC) and hospital mortality in patients with loop ileostomy (LI) who underwent ECI, compared with patients with LI who underwent late closure. Un- matched case-control study. Patients with LI who underwent surgery at Clínica RedSalud Mayor Temuco (2010-2022) were included. Cases were defined as patients with LI who underwent early closure and controls as subjects who underwent closure at the usual times. No matching was performed, but a 1:1 relationship between cases and controls was considered. Outcome variables were postoperative complications and hospital mortality. Other variables of interest were surgical time and hospital stay. Descriptive statistics were applied with calculation of proportions and measures of central tendency. Subsequently, t-test and Pearson Chi2 for comparison of averages and proportions was applied, and odds ratios and their respective 95 % CI were calculated. In this study 39 patients with AI were operated on (18 cases and 21 controls). Age and BMI average of the studied subjects was 71.3±7.1 years and 27.3±19.8 kg/m2 respectively. Mean LI closure time, surgical time, and hospitalization were: 10.0±0.7 months; 62.5±10.6min; 3.8±0.1 days respectively. POC were only surgical site infections. Three in cases (16.7 %) and 3 in controls (14.3 %). No anastomotic dehiscence or hospital mortality was observed in either cases or controls. There were no differences in comorbidities or surgical site infection between cases and controls (OR of 0.6 and 1.2 respectively) In this experience, the results of performing the CTI were similar to the late closing in relation to the variables studied.

El cierre temprano de una ileostomía en asa (IA), es una práctica relativamente nueva, sobre la que no hay suficiente evidencia respecto de su efectividad en relación con el cierre en tiempos convencionales. El objetivo de este estudio fue verificar diferencias en la tasa de complicaciones postoperatorias (CPO) y de mortalidad hospitalaria en pacientes con IA sometidos a cierre temprano comparados con pacientes con IA sometidos a cierre tardío. Estudio de casos y controles sin emparejamiento. Se incluyeron pacientes con IA que fueron sometidos a cirugía en la Clínica RedSalud Mayor Temuco (2010-2022). Los casos se definieron como pacientes con IA sometidos a cierre temprano y los controles como sujetos con IA sometidos a cierre en tiempos habituales. No se realizó emparejamiento. Se consideró una relación 1:1 entre casos y controles. Las variables de resultado fueron CPO y mortalidad hospitalaria. Otras variables de interés fueron: tiempo quirúrgico y hospitalización. Se aplicó estadísticas descriptivas (cálculo de proporciones y medidas de tendencia central). Posteriormente, se aplicó prueba t-test y Chi2 para comparación de promedios y proporciones; y se calcularon odds ratios e intervalos de confianza del 95 %. Se operaron 39 pacientes con IA (18 casos y 21 controles). El promedio de edad e IMC fue 71,3±7,1 años y 27,3±19,8 kg/m2, respectivamente. El tiempo promedio de cierre de IA, tiempo quirúrgico y hospitalización fueron: 10,0±0,7 meses; 62,5±10,6 minutos; 3,8±0,1 días, respectivamente. Las CPO fueron infecciones del sitio quirúrgico (3 casos; 16,7 % y 3 controles; 14,3 %). No se observó dehiscencia anastomótica ni mortalidad hospitalaria en casos ni controles. No hubo diferencias en comorbilidades ni en infecciones del sitio quirúrgico entre casos y controles (OR de 0,6 y 1,2, respectivamente). No se evidenciaron diferencias entre realizar cierre temprano o tardío de IA, respecto de las variables CPO y de mortalidad hospitalaria.

Mortalidad Materna en Venezuela: aspectos médicos y Políticas (1940 - 2016) / Materna Mortality in Venezuela: medical issues and Public Policy (1940 - 2016)

En la actualidad Venezuela se encuentra en una crisis social y económica sin precedentes. La mortalidad materna(MM) es un indicador en salud importante, debido a que permite tener idea de la atención médica de un país; se mide a través de dos indicadores: Razón de Mortalidad Materna (RMM) y Tasa de Mortalidad Materna (TMM). Objetivo: Revisar y compararla evolución de ambos indicadores de MM desde la década de 1930 hasta la década 2000. Métodos: Se realizó una revisión de la literatura y de informes técnicos de organismos gubernamentales y no gubernamentales para el análisis de la situación previa y reciente de esta situación en Venezuela. Los resultados señalan que existe una notable disminución de las cifras de MM como ha de esperarse con el mejoramiento de la tecnología desde la década de 1930 hasta el año 2000; posteriormente ocurre un retroceso de la sanidad pública con cifras comparables a la década de 1960. Concluimos que la MM ha sido desde tiempos pasados un problema constante en la salud pública; al pasar los años y gobiernos, se han implementado numerosas políticas públicas para mejorar esta situación, muchas de estas estrategias han sido fallidas debido a la falta de su continuidad y de su cumplimiento pleno.

Venezuela is currently in an unprecedented socialand economic crisis. Maternal mortality is an important health indicator because it provides an idea of a country's medical care. Maternal mortality is usually measured through two indicators: Maternal Mortality Ratio (MMR) and Maternal Mortality Rate. Objective: Review and compare the evolution of both healthindicators from the 1930s to 2016. Methods: A review of the literature and technical reports from governmental andnon-governmental organizations was carried out to analyze theprevious and recent situation. of this situation in Venezuela. Theresults indicate that there is a notable decrease in the figures ofmaternal mortality, as should be expected with the improvementof technology from the 1930s to the year 2000. Subsequently, there is a decline in public health with figures comparable to the1960s. We conclude that maternal mortality has been a constant problem in public health since ancient times. Over the years and governments, numerous public policies have been implementedto improve this situation. Many of these strategies have beenfailed due to lack of continuity and in the absence of its full compliance.

Análise longitudinal dos parâmetros ventilatórios e escore SOFA de pacientes com COVID-19 hospitalizados em uma UTI no Sul do Brasil / Longitudinal analysis of ventilatory parameters and SOFA score of patients with COVID-19 hospitalised in an ICU in southern Brazil

Introdução: embora o Coronavírus da Síndrome Respiratória Aguda Grave 2 (SARS-CoV-2) seja mais conhecido por causar patologias respiratórias substanciais, o vírus também pode resultar em várias manifestações extrapulmonares, sobretudo nas alas de cuidados intensivos. Frente a essas implicações multissistêmicas, a monitoração do suporte ventilatório e utilização do escore Sequential Organ Failure Assessment (SOFA) foram fundamentais no manejo do paciente crítico com COVID-19 nas Unidades de Terapia Intensiva (UTIs) durante a pandemia. Objetivo: esse estudo pretende analisar os parâmetros ventilatórios e escore SOFA de pacientes com COVID-19 numa UTI no sul do Brasil e as principais complicações ocasionadas. Metodologia: foi realizado um estudo de coorte retrospectivo que analisou prontuários de pacientes com diagnóstico de COVID-19 na UTI do Hospital Nossa Senhora da Conceição, no estado de Santa Catarina, entre março de 2020 a dezembro de 2021. Resultados: foram incluídos 448 pacientes, com média de idade de 58,5 (±15,1) anos, mediana de internação de 15 (9-24) dias e média de ventilação mecânica de 15 (±8,7) dias, evoluindo para óbito 63,3%. Durante a internação, 86,4% das pessoas sofreram complicações, dentre as mais prevalentes Insuficiência Renal Aguda (46,8%) seguida por Pneumonia Associada à Ventilação (41,9%) e Choque séptico (22%). Na evolução clínica, o escore SOFA e a relação da pressão parcial de oxigênio pela fração de oxigênio inspirado (PaO2/FiO2) foram fatores de desfecho desfavorável nas três semanas de internação, com SOFA ≥ 5 e relação PaO2/FiO2 < 200. Além disso, 3 dos 6 componentes do SOFA (renal, respiratório e coagulação) tiveram relação com a ocorrência de complicações. Conclusão: o escore SOFA e a relação PaO2/FiO2 tiveram relação no prognóstico de pacientes com COVID-19 durante as três semanas de internação na UTI. Além disso, o SOFA se mostrou um possível indicador de complicações intra-hospitalares durante a evolução clínica.

Introduction: although Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is best known for causing significant respiratory pathologies, the virus can also result in various extrapulmonary manifestations, particularly in intensive care wards. Faced with these multisystem implications, monitoring ventilatory support and using the Sequential Organ Failure Assessment (SOFA) score were fundamental in managing critically ill patients with COVID-19 in Intensive Care Units (ICUs) during the pandemic. Objective: this study will analyse the ventilatory parameters and SOFA score of patients with COVID-19 in an ICU in southern Brazil and the main complications caused. Methodology: a retrospective cohort study was carried out that analysed medical records of patients diagnosed with COVID-19 in the ICU of Hospital Nossa Senhora da Conceição, in the state of Santa Catarina, between March 2020 and December 2021. Results: 448 patients were included, with a mean age of 58.5 (±15.1) years, a median hospital stay of 15 (9-24) days, and mean mechanical ventilation of 15 (±8.7) days, with 63.3% dying. During hospitalisation, 86.4% of people suffered complications, among the most prevalent Acute Renal Failure (46.8%), followed by Ventilation Associated Pneumonia (41.9%) and Septic Shock (22%). In the clinical evolution, the SOFA score and the ratio of partial pressure of oxygen to the fraction of inspired oxygen (PaO2/FiO2) were factors of unfavourable outcome in the three weeks of hospitalisation, with SOFA ≥ 5 and PaO2/FiO2 ratio < 200. In addition, three of the six components of the SOFA (renal, respiratory and coagulation) were related to the occurrence of complications. Conclusion: the SOFA score and the PaO2/FiO2 ratio were related to the prognosis of patients with COVID-19 during the three weeks of ICU stay. Furthermore, the SOFA proved to be a possible indicator of in-hospital complications during clinical evolution.

Comorbilidades asociadas a la mortalidad por COVID-19 en adultos en Lima, Perú: un estudio de cohorte retrospectiva / Comorbidities associated with COVID-19 mortality in adults in Lima, Peru: a retrospective cohort study

RESUMEN Objetivos. Evaluar las comorbilidades asociadas a la mortalidad en pacientes adultos hospitalizados por COVID-19 de diferentes grupos de edad en hospitales de Lima y Callao. Materiales y métodos. En este estudio de cohorte retrospectiva analizamos datos de pacientes adultos hospitalizados por COVID-19, notificados al Sistema Nacional de Vigilancia Epidemiológica del Ministerio de Salud de Perú de marzo a octubre del 2020. Se estimaron riesgos relativos con intervalos de confianza al 95% mediante modelos de regresión de Poisson con varianza robusta para evaluar las comorbilidades asociadas a la mortalidad por grupos de edad: jóvenes (18-29 años), adultos (30-59 años) y mayores (≥60 años). Resultados. Se incluyeron 2366 jóvenes, 23781 adultos y 25356 adultos mayores en el análisis. Los adultos mayores presentaron la mortalidad más alta (63,7%) en comparación con adultos (27,1%) y jóvenes (8,5%). Independientemente del grupo de edad, la presencia de enfermedad neurológica, enfermedad renal, enfermedad hepática y cáncer se asoció a un mayor riesgo de mortalidad. Adicionalmente, la enfermedad cardiovascular fue también un factor de riesgo en los jóvenes; la obesidad, la diabetes, la enfermedad cardiovascular, la enfermedad pulmonar crónica y la inmunodeficiencia en los adultos; y la obesidad y la enfermedad pulmonar crónica en los mayores. Conclusiones: Independientemente de los grupos de edad, los individuos con enfermedad neurológica crónica, enfermedad renal, enfermedad hepática y cáncer tendrían un alto riesgo de morir por la COVID-19.

ABSTRACT Objectives. To evaluate comorbidities associated with mortality in adult patients hospitalized due to COVID-19 in hospitals in Lima and Callao. Materials and methods. In this retrospective cohort study, we analyzed data from adult patients hospitalized due to COVID-19 reported to the National Epidemiological Surveillance System of the Peruvian Ministry of Health from March to October 2020. We estimated relative risks with 95% confidence intervals using Poisson regression models with robust variance to assess comorbidities associated with mortality by age group: young adults (18-29 years), adults (30-59 years) and older adults (≥60 years). Results. We included 2366 young adults, 23,781 adults and 25,356 older adults. Older adults had the highest mortality (63.7%) compared to adults (27.1%) and young adults (8.5%). Regardless of age group, the presence of neurological disease, renal disease, liver disease, and cancer was associated with an increased risk of mortality. Additionally, cardiovascular disease was also a risk factor in young adults; obesity, diabetes, cardiovascular disease, chronic lung disease, and immunodeficiency in adults; and obesity and chronic lung disease in the elderly. Conclusions. Regardless of age groups, individuals with chronic neurologic disease, renal disease, liver disease, and cancer were at high risk of death from COVID-19.

The SOFA, APACHE II and SAPS II scales help to predict mortality efficiently in the early detection and treatment of patients with acute and high-risk disease.

Mortalidad perioperatoria en Tolima, perspectivas del cuarto indicador de The Lancet Commission on Global Surgery: Un análisis preliminar de la cohorte prospectiva del estudio Colombian Surgical Outcomes Study (ColSOS) / Perioperative mortality in Tolima and perspectives of the fourth indicator of The Lancet Commission on Global Surgery: A preliminary analysis of the prospective cohort of the Colombian Surgical Outcomes Study (ColSOS)

Introducción. La mortalidad perioperatoria en el mundo representa 4,2 millones de muertes anuales. El cuarto indicador de The Lancet Commission on Global Surgery permite estandarizar la mortalidad perioperatoria. En Colombia, existen aproximaciones por datos secundarios, limitando el análisis y las intervenciones aplicables a nuestra población. El objetivo de este estudio fue describir la mortalidad perioperatoria a través de datos primarios que permitan sustentar políticas públicas. Métodos. Se hizo el análisis preliminar de un estudio observacional, de cohorte prospectiva, multicéntrico en 6 instituciones del departamento de Tolima. Se incluyeron los pacientes llevados a procedimientos quirúrgicos por una semana, con posterior seguimiento hasta el egreso, fallecimiento o 30 días de hospitalización. La mortalidad perioperatoria fue el desenlace primario. Resultados. Fueron incluidos 378 pacientes, con mediana de 49 años (RIC 32-66), buen estado funcional (ASA I-II 80 %) y baja complejidad quirúrgica (42 %). Las cirugías más comunes fueron por Ortopedia (25,4 %) y Cirugía plástica (23,3 %). El 29,7 % presentaron complicaciones postoperatorias, las más comunes fueron síndrome de dificultad respiratoria agudo e íleo postoperatorio. La mortalidad perioperatoria fue de 1,3 %. Discusión. La mortalidad perioperatoria discrepó de la reportada en otros estudios nacionales, aun cuando los pacientes tenían un bajo perfil de riesgo y baja complejidad de los procedimientos. Sin embargo, coincide con la reportada internacionalmente y nos acerca a la realidad del país. Conclusión. La determinación del cuarto indicador es de vital importancia para mejorar la atención quirúrgica en Colombia. Este es el primer acercamiento con datos primarios que nos permite tener información aplicable a nuestra población

Introduction. Perioperative mortality accounts for 4.2 million deaths annually. The fourth indicator of The Lancet Commission on Global Surgery allows standardizing perioperative mortality. In Colombia, there are approximations based on secondary data, limiting the analysis and interventions applicable to our population. The objective of this study is to describe perioperative mortality through primary data that allow supporting public policies. Methods. A preliminary analysis of an observational, prospective cohort, multicenter study was carried out at six institutions in the District of Tolima. Patients undergoing surgical procedures were included for one week, for subsequent follow-up until discharge, death, or 30 days of hospitalization. Perioperative mortality was the primary outcome and was presented as a proportion. Results. A total of 378 patients were included, with a median age of 49 years (RIC 32-66), low-risk profile (ASA I-II 80%), and low surgical complexity (42%). The most common surgeries were Orthopedic (25.4%) and Plastic Surgery (23.3%). Postoperative complications occurred in 29.7%, the most common were ARDS and postoperative ileus. Perioperative mortality was 1.3%. Discussion. Perioperative mortality differed from that reported in national studies, even when the patients had a low-risk profile and low complexity of the procedures. However, it coincides with that reported internationally and brings us closer to the reality of the country. Conclusion. The determination of the fourth indicator is of vital importance to improving surgical care in Colombia. This is the first approach with primary data that allows us to have applicable information for our population

Mortality in patients with severe COVID-19 who underwent tracheostomy due to prolonged mechanical ventilation / Mortalidad en pacientes con COVID-19 grave sometidos a traqueostomía por ventilación mecánica prolongada

BACKGROUND: The usefulness of tracheostomy has been questioned in patients with COVID-19 and prolonged invasive mechanical ventilation (IMV). AIM: To compare the 90-day mortality rate of patients who underwent a tracheostomy due prolonged IMV with those that did not receive this procedure. MATERIAL AND METHODS: We studied a historical cohort of 92 patients with COVID-19 and prolonged IMV (> 10 days). The primary outcome was the 90-day mortality rate. Secondary outcomes included days on IMV, hospital/intensive care unit (ICU) length of stay, frequency of nosocomial infections, and thrombotic complications demonstrated by images. A logistic regression was performed to adjust the effect of tracheostomy by SOFA score and days on IMV. RESULTS: Forty six patients aged 54 to 66 years (72% males) underwent tracheostomy. They had a median of two comorbidities, and received the procedure after a median of 20.5 days on IMV (interquartile range: 17-26). 90-day mortality was lower in patients who were tracheostomized than in the control group (6.5% vs. 32.6%, p-value < 0.01). However, after controlling for confounding factors, no differences were found in mortality between both groups (relative risk = 0.303, p-value = 0.233). Healthcare-associated infections and hospital/ICU length of stay were higher in patients with tracheostomy than in controls. Thrombotic complications occurred in 42.4% of the patients, without differences between both groups. No cases of COVID-19 were registered in the healthcare personnel who performed tracheostomies. CONCLUSIONS: In patients with COVID-19 undergoing prolonged IMV, performing a tracheostomy is not associated with excess mortality, and it is a safe procedure for healthcare personnel.

ANTECEDENTES: La utilidad de la traqueostomía en pacientes COVID-19 sometidos a ventilación mecánica invasiva (VMI) prolongada ha sido cuestionada. OBJETIVO: Comparar la mortalidad a 90 días en estos pacientes, con y sin traqueostomía. MATERIAL Y MÉTODOS: Estudiamos una cohorte histórica de 92 pacientes COVID-19 con VMI prolongada (>10 días). El desenlace prima-rio fue mortalidad a 90 días. Se consideraron desenlaces secundarios los días en VMI, estadía hospitalaria/UCI, frecuencia de infecciones nosocomiales, y eventos trombóticos. Mediante regresión logística se ajustó el efecto de la traqueostomía en la mortalidad, por SOFA y días de VMI. RESULTADOS: Cuarenta y seis pacientes de 54 a 66 años (72% hombres) fueron traqueostomizados. Ellos tenían una mediana de dos comorbilidades, y recibieron el procedimiento luego de una mediana de 20,5 días en VMI (rango intercuartílico: 17-26). En el análisis crudo, la mortalidad a 90 días fue menor en los pacientes con traqueostomía que en el grupo control (6,5% vs. 32,6%; p < 0,001). No obstante, luego de controlar por factores de confusión, no se encontraron diferencias en mortalidad (riesgo relativo 0,303; p = 0,233). Las infecciones asociadas a la atención de salud y la estadía en hospital/UCI fueron mayores en los pacientes traqueostomizados que en los controles. Los eventos trombóticos ocurrieron en el 42,4% de los pacientes, sin diferencias entre grupos. No hubo casos de COVID-19 en el personal de salud que realizó las traqueostomías. CONCLUSIONES: En pacientes con COVID-19 sometidos a VMI prolongada, la realización de una traqueostomía no se asocia a un exceso de mortalidad, y es un procedimiento seguro para el personal sanitario.

Impacto de Marcadores Inflamatórios no Prognóstico de Pacientes Oncológicos Internados no Instituto Nacional de Câncer com SARS-CoV-2 na Primeira Onda da Pandemia no Brasil / Impact of Inflammatory Markers on the Prognosis of Patients with Cancer Admitted to the National Cancer Institute with SARS-CoV-2 in the First Wave of the Pandemic in Brazil / Impacto de los Marcadores Inflamatorios en el Pronóstico de Pacientes con Cáncer Ingresados en el Instituto Nacional del Cáncer con SARS-CoV-2 en la Primera Ola de la Pandemia en el Brasil

Introdução: O intenso processo inflamatório desencadeado pela covid-19 tem sido apontado por diversos autores. Objetivo: Avaliar o impacto de marcadores inflamatórios no prognóstico de pacientes com tumores sólidos internados com SARS-CoV-2/covid-19 na primeira onda da pandemia no Brasil. Método: Estudo de coorte com pacientes maiores de 18 anos com câncer, internados em um centro público de referência no tratamento oncológico, com SARS-CoV-2/covid-19, no período de março a setembro de 2020. Os seguintes marcadores inflamatórios foram analisados: razão neutrófilo-linfócito (RNL), derivação da razão neutrófilo-linfócito (dRNL) e razão plaqueta-linfócito (RPL). Foi considerado desfecho deste estudo a ocorrência de óbito durante a internação hospitalar. A associação entre as variáveis independentes e o desfecho foi analisada por meio de regressão logística univariada e múltipla. Resultados: Dos 185 pacientes, a maioria apresentava idade < 65 anos (61,1%), performance status (PS) ≥ 2 (82,4%) e estavam em tratamento oncológico (80,0%). O câncer de mama foi o tumor mais frequente (26,5%). Para a maior parte dos casos, o tempo de internação foi ≥ 5 dias (59,5%) e ocorreu em unidade de tratamento intensivo (84,3%). Durante a internação, 86 (46,5%) pacientes evoluíram para óbito. Na análise ajustada, apenas a RNL elevada (≥ 4,44) esteve associada ao risco de morrer (OR 3,54; IC 95%; 1,68 - 7,46; p = 0,001). Conclusão: A RNL se mostrou um importante marcador prognóstico, e níveis acima do seu valor mediano estiveram relacionados ao aumento do risco de morte durante a internação hospitalar

Introduction: The intense inflammatory process triggered by COVID-19 has been pointed out by several authors. Objective: To evaluate the impact of inflammatory markers on the prognosis of patients with solid tumors hospitalized with SARS-CoV-2/COVID-19 in the first wave of the pandemic in Brazil. Method: A cohort study of patients >18 years old with cancer, hospitalized at a public cancer treatment reference center, with SARS-CoV-2/COVID-19 from March to September 2020. The following inflammatory markers were analyzed: neutrophil-lymphocyte ratio (NLR), derivation of the neutrophil-lymphocyte ratio (dNLR) and platelet-lymphocyte ratio (PLR). The outcome of this study was death during hospitalization. The association between the independent variables and the outcome was analyzed using univariate and multiple logistic regression. Results: Of the 185 patients, most were aged < 65 years (61.1%), had performance status (PS) ≥ 2 (82.4%) and were in cancer treatment (80.0%). Breast cancer was the most frequent tumor (26.5%). For the majority of the cases, the length of hospital stay was ≥ 5 days (59.5%) and occurred in the intensive treatment unit (84.3%). During hospitalization, 86 (46.5%) patients progressed to death. In the adjusted analysis only high NLR (≥ 4.44) was associated with the risk of death (OR 3.54; 95% CI; 1.68 - 7.46; p = 0.001). Conclusion: NLR proved to be an important prognostic marker, and levels above its median value were related to an increased risk of death during hospitalization

Introducción: El papel de la inflamación desencadenada por la COVID-19 ha sido señalado por varios autores. Objetivo: Evaluar el impacto de los marcadores inflamatorios en el pronóstico de pacientes con tumores sólidos hospitalizados por SARS-CoV-2/COVID-19 en la primera ola de la pandemia en el Brasil. Método: Estudio de cohorte con pacientes >18 años con cáncer, ingresados en un centro público de referencia en el tratamiento del cáncer, con SARS-CoV-2/COVID-19 de marzo a septiembre de 2020. Se evaluaron los siguientes marcadores inflamatorios: relación neutrófilos-linfocitos (RNL), derivación de la relación neutrófilos-linfocitos (dRNL) y relación plaquetas-linfocitos (RPL). Se consideró como desenlace de este estudio la ocurrencia de muerte durante la hospitalización. La asociación entre las variables independientes y el desenlace se analizó mediante regresión logística univariada y múltiple. Resultados: De los 185 pacientes hospitalizados, la mayoría tenía una edad < 65 años (61,1%), un performance status (PS) ≥ 2 (82,4%) y estaban en tratamiento oncológico (80,0 %). El cáncer de mama fue el tumor más frecuente (26,5%). Para la mayoría de los casos, el tiempo de hospitalización fue ≥ 5 días (59,5%) y ocurrió en la unidad de tratamiento intensivo (84,3%). Durante la hospitalización, 86 (46,5%) pacientes terminaron falleciendo. En el análisis ajustado, solo una RNL alta (≥ 4,44) se asoció con el riesgo de muerte (OR 3,54; IC 95%; 1,68 - 7,46; p = 0,001). Conclusión: La RNL demostró ser un importante marcador pronóstico, y los niveles por encima de su valor medio se relacionaron con un mayor riesgo de muerte durante la hospitalización

Perioperative mortality and morbidity of hip fractures among COVID-19 infected and non-infected patients: A systematic review and meta-analysis / 中华创伤杂志(英文版)

PURPOSE@#Hip fractures among elderly patients are surgical emergencies. During COVID-19 pandemic time, many such patients could not be operated at early time because of the limitation of the medical resources, the risk of infection and redirection of medical attention to a severe infective health problem.@*METHODS@#A search of electronic databases (PubMed, Medline, CINAHL, EMBASE and the Cochrane Central Register of Controlled Trials) with the keywords "COVID", "COVID-19″, "SARS-COV-2", "Corona", "pandemic", "hip fracture", "trochanteric fracture" and "neck femur fracture" revealed 64 studies evaluating treatment of hip fracture in elderly patients during COVID-19 pandemic time. The 30-day mortality rate, inpatient mortality rate, critical care/special care need, readmission rate and complications rate in both groups were evaluated. Data were analyzed using Review Manager (RevMan) V.5.3.@*RESULTS@#After screening, 7 studies were identified that described the mortality and morbidity in hip fractures in both COVID-19 infected (COVID-19 +) and non-infected (COVID-19 -) patients. There were significantly increased risks of 30-day mortality (32.23% COVID-19 + death vs. 8.85% COVID-19 - death) and inpatient mortality (29.33% vs. 2.62%) among COVID-19 + patients with odds ratio (OR) of 4.84 (95% CI: 3.13 - 7.47, p < 0.001) and 15.12 (95% CI: 6.12 - 37.37, p < 0.001), respectively. The COVID-19 + patients needed more critical care admission (OR = 5.08, 95% CI: 1.49 - 17.30, p < 0.009) and they remain admitted for a longer time in hospital (mean difference = 3.6, 95% CI: 1.74 - 5.45, p < 0.001); but there was no difference in readmission rate between these 2 groups. The risks of overall complications (OR = 17.22), development of pneumonia (OR = 22.25), and acute respiratory distress syndrome/acute respiratory failure (OR = 32.96) were significantly high among COVID-19 + patients compared to COVID-19 - patients.@*CONCLUSIONS@#There are increased risks of the 30-day mortality, inpatient mortality and critical care admission among hip fracture patients who are COVID-19 +. The chances of developing pneumonia and acute respiratory failure are more in COVID-19 + patients than in COVID-19 ‒ patients.

Covid-19 hospital mortality using spatial hierarchical models: cohort design with 74, 994 registers

ABSTRACT OBJECTIVE To investigate the relationship between covid-19 hospital mortality and risk factors, innovating by considering contextual and individual factors and spatial dependency and using data from the city of São Paulo, Brazil. METHODS The study was performed with a spatial hierarchical retrospective cohort design using secondary data (individuals and contextual data) from hospitalized patients and their geographic unit residences. The study period corresponded to the first year of the pandemic, from February 25, 2020 to February 24, 2021. Mortality was modeled with the Bayesian context, Bernoulli probability distribution, and the integrated nested Laplace approximations. The demographic, distal, medial, and proximal covariates were considered. RESULTS We found that per capita income, a contextual covariate, was a protective factor (odds ratio: 0.76 [95% credible interval: 0.74-0.78]). After adjusting for income, the other adjustments revealed no differences in spatial dependence. Without income inequality in São Paulo, the spatial risk of death would be close to one in the city. Other factors associated with high covid-19 hospital mortality were male sex, advanced age, comorbidities, ventilation, treatment in public healthcare settings, and experiencing the first covid-19 symptoms between January 24 and February 24, 2021. CONCLUSIONS Other than sex and age differences, geographic income inequality was the main factor responsible for the spatial differences in the risk of covid-19 hospital mortality. Investing in public policies to reduce socioeconomic inequities, infection prevention, and other intersectoral measures should focus on lower per capita income, to control covid-19 hospital mortality.

Hospital mortality from covid-19 in children and adolescents in Brazil in 2020-2021 / Mortalidade hospitalar por covid-19 em crianças e adolescentes no Brasil em 2020-2021

ABSTRACT OBJECTIVE To describe cases, deaths, and hospital mortality from covid-19 in children and adolescents in Brazil, according to age group, during the evolving phases of the pandemic in 2020 and 2021. METHODS Census of patients aged up to 19 committed with severe acute respiratory syndrome, due to covid-19 or unspecified, notified to the Brazilian Influenza Epidemiological Surveillance Information System, from January 1, 2020, to December 31, 2021. The two years were divided into six phases, covering the spread of the disease—first, second and third wave—as well as the impact of vaccination. The pediatric population was categorized into infants, preschoolers, schoolchildren, and adolescents. Hospital mortality was assessed by pandemic phase and age group. RESULTS A total of 144,041 patients were recorded in the two years, 18.2% of whom had confirmed cases of covid-19. Children under 5 years old (infants and preschoolers) accounted for 62.8% of those hospitalized. A total of 4,471 patients died, representing about 6.1 deaths per day. Infants were the ones who most progressed to the intensive care unit (24.7%) and had the highest gross number of deaths (n = 2,012), but mortality was higher among adolescents (5.7%), reaching 9.8% in phase 1. The first peak of deaths occurred in phase 1 (May/2020), and two other peaks occurred in phase 4 (March/2021 and May/2021). There was an increase in cases and deaths for younger ages since phase 4. Hospital mortality in the pediatric population was higher in phases 1, 4, and 6, following the phenomena of dissemination/interiorization of the virus in the country, beginning of the second wave and beginning of the third wave, respectively. CONCLUSION The absolute number of cases of covid-19 in children and adolescents is significant. Although complete vaccination in descending order of age provided a natural deviation in age range, there was a greater gap between the curve of new hospitalized cases and the curve of deaths, indicating the positive impact of immunization.

RESUMO OBJETIVO Descrever casos, óbitos e mortalidade hospitalar por covid-19 em crianças e adolescentes no Brasil, conforme faixa etária, durante as fases de evolução da pandemia em 2020 e 2021. MÉTODOS Censo de pacientes de até 19 anos internados com síndrome respiratória aguda grave, por covid-19 ou não especificada, notificados ao Sistema de Informação de Vigilância Epidemiológica da Gripe do Brasil, entre 1 de janeiro de 2020 e 31 de dezembro de 2021. Os dois anos foram divididos em seis fases, abrangendo a disseminação da doença − primeira, segunda e terceira onda −, bem como o impacto da vacinação. A população pediátrica foi categorizada em lactentes, pré-escolares, escolares e adolescentes. A mortalidade hospitalar foi avaliada por fase da pandemia e faixa etária. RESULTADOS Foram contabilizados 144.041 pacientes nos dois anos, sendo 18,2% casos de covid-19 confirmados. Menores de 5 anos (lactentes e pré-escolares) corresponderam a 62,8% dos hospitalizados. Evoluíram a óbito 4.471, representando cerca 6,1 óbitos por dia. Os lactentes foram os que mais evoluíram para unidade de terapia intensiva (24,7%) e apresentaram o maior número bruto de óbito (n = 2.012), porém a mortalidade foi maior entre os adolescentes (5,7%), chegando a 9,8% na fase 1. O primeiro pico de óbitos ocorreu na fase 1 (maio/2020), e outros dois picos ocorreram na fase 4 (março/2021 e maio/2021). Verificou-se avanço de casos e óbitos para as idades inferiores desde a fase 4. A mortalidade hospitalar na população pediátrica foi maior nas fases 1, 4 e 6, acompanhando os fenômenos de disseminação/interiorização do vírus no país, início da segunda onda e início da terceira onda, respectivamente. CONCLUSÃO O número absoluto de casos de covid-19 em crianças e adolescentes é expressivo. Embora a vacinação completa em ordem decrescente de idade tenha proporcionado um desvio natural de faixa etária, ocorreu um distanciamento maior entre a curva de novos casos hospitalizados e a curva de óbitos, indicando o impacto positivo da imunização.

Clinical characteristics and prognostic analysis of female patients with Stanford type B aortic dissection / 中华心血管病杂志

Objective: To explore the clinical characteristics and prognostic factors of female patients with Stanford type B aortic dissection. Methods: This is a single-centre retrospective study. Consecutive patients diagnosed with Stanford type B aortic dissection in General Hospital of Northern Theater Command from June 2002 to August 2021 were enrolled, and grouped based on sex. According to the general clinical conditions and complications of aortic dissection tear, patients were treated with thoracic endovascular aortic repair, surgery, or optimal medication. The clinical characteristics and aortic imaging data of the patients at different stages were collected, adverse events including all-cause deaths, stroke, and occurrence of aortic-related adverse events were obtained during hospitalization and within 30 days and at 1 and 5 years after discharge. According to the time of death, death was classified as in-hospital death, out-of-hospital death, and in-hospital death was divided into preoperative death, intraoperative death and postoperative death. According to the cause of death, death was classified as aortic death, cardiac death and other causes of death. Aortic-related adverse events within 30 days after discharge included new paraplegia, post-luminal repair syndrome, and aortic death; long-term (≥1 year after discharge) aortic-related adverse events included aortic death, recurrent aortic dissection, endoleak and distal ulcer events. The clinical characteristics, short-term and long-term prognosis was compared between the groups. Logistic regression analysis was used to explore the association between different clinical factors and all-cause mortality within 30 days in female and male groups separately. Results: A total of 1 094 patients with Stanford type B aortic dissection were enrolled, mean age was (53.9±12.1) years, and 861 (78.7%) were male and 233 (21.3%) were female. (1) Clinical characteristics: compared with male patients, female patients were featured with older average age, higher proportion of aged≥60 years old, back pain, anemia, optimal medication treatment, and higher cholesterol level; while lower proportion of smoking and drinking history, body mass index, calcium antagonists use, creatine kinase level, and white blood cell count (all P<0.05). However, there was no significant difference in dissection tear and clinical stage, history of coronary heart disease, diabetes, hypertension, and cerebrovascular disease between female and male patients (all P>0.05). (2) Follow-up result: compared with male patients, female patients had a higher rate of 30-day death [6.9% (16/233) vs. 3.8% (33/861), P=0.047], in-hospital death (5.6% (13/233) vs. 2.7% (23/861), P=0.027), preoperative death (3.9% (9/233) vs. 1.5% (12/861), P=0.023) and aorta death (6.0% (14/233) vs. 3.1% (27/861), P=0.041). The 1-year and 5-year follow-up results demonstrated that there were no significant differences in death, cerebrovascular disease, and aorta-related adverse events between the two groups (all P>0.05). (3) Prognostic factors: the results of the univariate logistic regression analysis showed that body mass index>24 kg/m2 (HR=1.087, 95%CI 1.029-1.149, P=0.013), history of anemia (HR=2.987, 95%CI 1.054-8.468, P=0.032), hypertension (HR=1.094, 95%CI 1.047-1.143, P=0.040) and troponin-T>0.05 μg/L (HR=5.818, 95%CI 1.611-21.018, P=0.003)were associated with an increased risk of all-cause mortality within 30 days in female patients. Conclusions: Female patients with Stanford type B aortic dissection have specific clinical characteristics, such as older age at presentation, higher rates of anemia and combined back pain, and higher total cholesterol levels. The risk of death within 1 month is higher in female patients than in male patients, which may be associated with body mass index, hypertension, anemia and troponin-T, but the long-term prognosis for both female and male patients is comparable.

Low diastolic blood pressure and adverse outcomes in inpatients with acute exacerbation of chronic obstructive pulmonary disease: A multicenter cohort study / 中华医学杂志(英文版)

BACKGROUND@#Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients.@*METHODS@#Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes.@*RESULTS@#Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality.@*CONCLUSION@#Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.@*CLINICAL TRIAL REGISTRATION@#Chinese Clinical Trail Registry, No. ChiCTR2100044625.

Changes in process and outcome for ST elevation myocardial infarction in central China from 2011 to 2018 / 中华医学杂志(英文版)

BACKGROUND@#Limited data are available on the changes in the quality of care for ST elevation myocardial infarction (STEMI) during China's health system reform from 2009 to 2020. This study aimed to assess the changes in care processes and outcome for STEMI patients in Henan province of central China between 2011 and 2018.@*METHODS@#We compared the data from the Henan STEMI survey conducted in 2011-2012 ( n = 1548, a cross-sectional study) and the Henan STEMI registry in 2016-2018 ( n = 4748, a multicenter, prospective observational study). Changes in care processes and in-hospital mortality were determined. Process of care measures included reperfusion therapies, aspirin, P2Y12 antagonists, β-blockers, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and statins. Therapy use was analyzed among patients who were considered ideal candidates for treatment.@*RESULTS@#STEMI patients in 2016-2018 were younger (median age: 63.1 vs . 63.8 years) with a lower proportion of women (24.4% [1156/4748] vs . 28.2% [437/1548]) than in 2011-2012. The composite use rate for guideline-recommended treatments increased significantly from 2011 to 2018 (60.9% [5424/8901] vs . 82.7% [22,439/27,129], P <0.001). The proportion of patients treated by reperfusion within 12 h increased from 44.1% (546/1237) to 78.4% (2698/3440) ( P <0.001) with a prolonged median onset-to-first medical contact time (from 144 min to 210 min, P <0.001). The use of antiplatelet agents, statins, and β-blockers increased significantly. The risk of in-hospital mortality significantly decreased over time (6.1% [95/1548] vs . 4.2% [198/4748], odds ratio [OR]: 0.67, 95% confidence interval [CI]: 0.50-0.88, P = 0.005) after adjustment.@*CONCLUSIONS@#Gradual implementation of the guideline-recommended treatments in STEMI patients from 2011 to 2018 has been associated with decreased in-hospital mortality. However, gaps persist between clinical practice and guideline recommendation. Public awareness, reperfusion strategies, and construction of chest pain centers need to be further underscored in central China.

Role of coagulation dysfunction in thrombocytopenia-related death in patients with septic shock / 中华危重病急救医学

OBJECTIVE@#To explore the effect of thrombocytopenia on the prognosis of patients with septic shock and its mechanism in leading to death.@*METHODS@#A retrospective case-control study was conducted. Patients with septic shock admitted to emergency intensive care unit (EICU) and intensive care unit (ICU) in Peking University People's Hospital from April 1, 2015 to January 31, 2023 were enrolled. Patients were divided into the thrombocytopenia group and the non-thrombocytopenia group, according to whether the minimum platelet count was less than 100×109/L within 24 hours after admission to ICU. The outcome index was the mortality during ICU stay. The baseline data, hospitalization information and laboratory test results of the two groups were compared, and the risk factors of in-hospital death were analyzed by Logistic regression, and the mediation effect was performed by Bootstrap method.@*RESULTS@#A total of 301 patients with septic shock were enrolled, of which 172 (57.1%) had thrombocytopenia and 129 (42.9%) did not. There were significant differences between the two groups in age, mortality, disseminated intravascular coagulation (DIC), continuous renal replacement therapy, and level of creatinine, urea nitrogen, total bilirubin, white blood cell count, lymphocyte count, prothrombin time (PT) and activated partial thromboplastin time (APTT). Univariate Logistic regression analysis showed thrombocytopenia [odds ratio (OR) = 4.478], continuous renal replacement therapy (OR = 4.601), DIC (OR = 6.248), serum creatinine (OR = 1.005), urea nitrogen (OR = 1.126), total bilirubin (OR = 1.006) and PT (OR = 1.126) were risk factors of death during hospitalization in patients with septic shock (all P < 0.05). Multivariate Logistic regression analysis showed that thrombocytopenia [OR = 3.338, 95% confidence interval (95%CI) was 1.910-5.834, P = 0.000], continuous renal replacement therapy (OR = 3.175, 95%CI was 1.576-6.395, P = 0.001) and PT (OR = 1.077, 95%CI was 1.011-1.147, P = 0.021) were independent risk factors for in-hospital mortality in patients with septic shock. Mediation analysis showed that 51% of the deaths due to thrombocytopenia in patients with septic shock were due to coagulopathy.@*CONCLUSIONS@#Thrombocytopenia is a powerful predictor of death in septic shock patients, and half of all thrombocytopenia-related deaths may be due to abnormal coagulation function.

Predictive value of hemoglobin to serum creatinine ratio combined with serum uric acid for in-hospital mortality after emergency percutaneous coronary intervention in patients with acute myocardial infarction / 中华危重病急救医学

OBJECTIVE@#To investigate the clinical value of hemoglobin to serum creatinine ratio (Hb/SCr) combined with blood uric acid (SUA) in predicting in-hospital mortality after emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).@*METHODS@#The clinical data of AMI patients who underwent emergency PCI in the First Affiliated Hospital of Kangda College of Nanjing Medical University from January 2017 to December 2021 were retrospectively analyzed. The general information, underlying medical history, blood routine, liver and kidney function, blood coagulation routine, SUA and other indicators were collected from patients. The primary composite endpoint was defined as in-hospital death, including in-hospital all-cause death during PCI and 15-day post-procedure hospitalization. Multivariate Logistic regression was used to analyze factors associated with in-hospital death after emergency PCI in patients with AMI. Multivariate Logistic regression was used to analyze the independent related factors and construct a risk prediction model. The Hosmer-Lemeshow method and receiver operator characteristic curve (ROC curve) were used to test the goodness of fit and predictive effect of the model and correlates, respectively.@*RESULTS@#A total of 1 976 patients were enrolled, 92 died in hospital and 1 884 survived. SUA was higher in the death group than that in the survival group (μmol/L: 476.88±132.04 vs. 354.87±105.31, P < 0.01), and the Hb/SCr ratio was significantly lower than that in the survival group (13.84±5.48 vs.19.20±5.74, P < 0.01). Pearson analysis showed a linear negative correlation between SUA and Hb/SCr ratio (r = -0.502, P < 0.01). Logistic regression risk model analysis finally included age [odds ratio (OR) = 0.916], Hb/SCr ratio (OR = 0.182), white blood cell count (WBC, OR = 2.733), C-reactive protein (CRP, OR = 3.611), SUA (OR = 4.667), blood glucose (Glu, OR = 2.726), homocysteine (Hcy, OR = 2.688) 7 factors to construct a risk prediction model, which were independent correlation factors for in-hospital death in AMI patients after emergency PCI (all P < 0.05). Hosmer-Lemeshow test verified the fitting effect of the model, and the result showed P = 0.447. The area under the ROC curve (AUC) of the model for predicting in-hospital death in AMI patients after emergency PCI was 0.764 [95% confidence interval (95%CI) was 0.712-0.816, P = 0.001]. When the cut-off value was 0.565 8, the sensitivity was 70.7%, the specificity was 70.2%, and the Yoden index was 0.410. When Hb/SCr ratio+SUA, SUA, Hb/SCr ratio, Hb and SCr were used to predict in-hospital death in AMI patients after emergency PCI, the AUC of Hb/SCr ratio+SUA was the largest, which was 0.810. When the optimal cut-off value was -0.847, the sensitivity was 77.7%, the specificity was 74.5%, and the Youden index was 0.522.@*CONCLUSIONS@#Age, SUA, Hb/SCr ratio, WBC, CRP, Glu, and Hcy are independent risk factors for in-hospital death after emergency PCI in AMI patients. The lower the Hb/SCr ratio and the higher the SUA at admission, the higher the risk of in-hospital death after emergency PCI in AMI patients. Hb/SCr ratio combined with SUA has a higher predictive value for in-hospital death after emergency PCI in AMI patients than single index, which is helpful for early identification of high-risk patients.
