Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay / In-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay

Introducción: los pacientes con COVID-19 ingresan en mayor proporción a asistencia respiratoria mecánica, aumentando: el riesgo de neumonía asociada a ventilador (NAV) las tasas de mortalidad, los días de permanencia en las unidades de terapia intensiva (UCI) y los costos sanitarios. Objetivo: determinar la Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay durante los años 2020 a 2021. Metodología: estudio analítico de tipo cohorte retrospectiva. Se registraron variables demográficas, comorbilidades, puntajes en scores de gravedad como el APACHE II al ingreso, la cifra más baja de oxigenación durante la internación expresado por la PaO2 / FIO2, días de ventilación, colocación en decúbito prono, traqueotomía, medidas terapéuticas farmacológicas y no farmacológicas, días de internación, así como las complicaciones y la mortalidad. Resultados: fueron incluidos 214 pacientes, 135 ingresaron a asistencia respiratoria mecánica (ARM) de los cuales 58 (42,9 %) desarrollaron NAV, con edad mediana de 52 años (40-60). Los microorganismos de NAV fueron cocos Gram negativos en 98,3 %, incluyendo Acinetobacter baumanii en 46,5 %, Klebsiella pneumoniae en 22,8 %, Pseudomona aeruginosa en 15,5 % y 5,2 % Stenotrophomona maltofilia. La mortalidad intrahospitalaria fue del 44,8 %. Los menores de 50 años tienen una sobrevida mayor que los mayores (34 días vs 22 días, con p de 0,026). Conclusión: la mortalidad intrahospitalaria fue del 44,8 %. La edad fue un factor de riesgo independiente para la mortalidad en pacientes con NAV, por lo que los profesionales de la salud deben estar atentos a la posibilidad de NAV en pacientes que requieren asistencia respiratoria mecánica, especialmente en pacientes mayores de 50 años.

Introduction: patients with COVID-19 are more likely to require mechanical ventilation, which increases the risk of ventilator-associated pneumonia (VAP), mortality rates, length of stay in intensive care units (ICUs), and healthcare costs. Objective: to determine the in-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay during the years 2020 to 2021. Methodology: this is a retrospective cohort analytical study. Demographic variables, comorbidities, severity scores such as APACHE II on admission, the worst oxygenation during hospitalization expressed by PaO2/FiO2, days of ventilation, prone position, tracheostomy, pharmacological and non-pharmacological therapeutic measures, days of hospitalization, as well as complications and mortality were recorded. Results: a total of 214 patients were included, 135 were admitted to mechanical ventilation (MRA), of which 58 (42.9%) developed VAP, with a median age of 52 years (40-60). VAP microorganisms were Gram-negative cocci in 98.3%, including Acinetobacter baumanii in 46.5%, Klebsiella pneumoniae in 22.8%, Pseudomona aeruginosa in 15.5%, and Stenotrophomona maltophilia in 5.2%. In-hospital mortality was 44.8%. Those under 50 years of age have a longer survival than those older (34 days vs. 22 days, with p of 0.026). Conclusion: the overall mortality rate was 44.8%. Age was an independent risk factor for mortality in patients with VAP, so healthcare professionals should be aware of the possibility of VAP in patients who require mechanical ventilation, especially in patients over 50 years of age.

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.

Razão de mortalidade hospitalar padronizada: limites e potencialidades do indicador para a avaliação do desempenho hospitalar no Sistema Único de Saúde, Brasil / Hospital standardized mortality ratio: limits and potential of the indicator for assessing hospital performance in the Brazilian Unified National Health System / Razón de mortalidad hospitalaria estandarizada: límites y potencialidades del indicador para la evaluación del desempeño hospitalario en el Sistema Único de Salud, Brasil

Resumo: Análises comparativas, baseadas em indicadores de desempenho clínico, para monitorar a qualidade da assistência hospitalar vêm sendo realizadas há décadas em vários países, com destaque para a razão de mortalidade hospitalar padronizada (RMHP). No Brasil, ainda são escassos os estudos e a adoção de instrumentos metodológicos que permitam análises regulares do desempenho das instituições. O objetivo deste artigo foi explorar o uso da RMHP para a comparação do desempenho dos hospitais remunerados pelo Sistema Único de Saúde (SUS). O Sistema de Informações Hospitalares foi a fonte de dados sobre as internações de adultos realizadas no Brasil entre 2017 e 2019. A abordagem metodológica para estimar a RMHP foi adaptada aos dados disponíveis e incluiu as causas de internação (diagnóstico principal) responsáveis por 80% dos óbitos. O número de óbitos esperados foi estimado por um modelo de regressão logística que incluiu variáveis preditoras amplamente descritas na literatura. A análise foi realizada em duas etapas: (i) nível da internação e (ii) nível do hospital. O modelo final de ajuste de risco apresentou estatística C de 0,774, valor considerado adequado. Foi observada grande variação da RMHP, especialmente entre os hospitais com pior desempenho (1,54 a 6,77). Houve melhor desempenho dos hospitais privados em relação aos hospitais públicos. Apesar de limites nos dados disponíveis e desafios ainda vislumbrados para a sua utilização mais refinada, a RMHP é aplicável e tem potencial para se tornar um elemento importante na avaliação do desempenho hospitalar no SUS.

Abstract: Comparative analyses based on clinical performance indicators to monitor the quality of hospital care have been carried out for decades in several countries, most notably the hospital standardized mortality ratio (HSMR). In Brazil, studies and the adoption of methodological tools that allow regular analysis of the performance of institutions are still scarce. This study aimed to assess the use of HSMR to compare the performance of hospitals funded by the Brazilian Unified National Health System (SUS). The Hospital Information System was the source of data on adult hospitalizations in Brazil from 2017 to 2019. The methodological approach to estimate HSMR was adapted to the available data and included the causes of hospitalization (main diagnosis) responsible for 80% of deaths. The number of expected deaths was estimated using a logistic regression model that included predictor variables widely described in the literature. The analysis was conducted in two stages: (i) hospitalization level and (ii) hospital level. The final risk adjustment model showed a C-statistic of 0.774, which is considered adequate. The variation in HSMR was wide, especially among the worst-performing hospitals (1.54 to 6.77). Private hospitals performed better than public hospitals. Although the limits of the available data and the challenges still face its more refined use, HSMR is applicable and has the potential to become an important tool for assessing hospital performance in the SUS.

Resumen: Durante décadas se han realizado en varios países análisis comparativos basados en indicadores de desempeño clínico para monitorear la calidad de la atención hospitalaria, con énfasis en la razón de mortalidad hospitalaria estandarizada (RMHE). En Brasil, aún son escasos los estudios y la adopción de instrumentos metodológicos que permitan análisis regulares del desempeño de las instituciones. El objetivo fue explorar el uso de la RMHE para comparar el desempeño de los hospitales remunerados por el Sistema Único de Salud (SUS). El Sistema de Información Hospitalaria fue la fuente de datos sobre las hospitalizaciones de adultos realizadas en Brasil entre el 2017 y el 2019. El enfoque metodológico para estimar la RMHE se adaptó a los datos disponibles e incluyó las causas de hospitalización (diagnóstico principal) responsables del 80% de las muertes. El número de muertes esperadas se estimó mediante un modelo de regresión logística que incluyó variables predictoras ampliamente descritas en la literatura. El análisis se realizó en dos etapas: (i) nivel de la hospitalización y (ii) nivel del hospital. El modelo final de ajuste de riesgo presentó una estadística C de 0,774, valor considerado adecuado. Se observó una gran variación en la RMHE, especialmente entre los hospitales con peor desempeño (1,54 a 6,77). Hubo un mejor desempeño de los hospitales privados en comparación con los hospitales públicos. A pesar de las limitaciones de los datos disponibles y de los desafíos aún previstos para su uso más refinado, la RMHE es aplicable y tiene el potencial de convertirse en un elemento importante en la evaluación del desempeño hospitalario en el SUS.

Nationwide study of in-hospital maternal mortality in Ecuador, 2015-2022 / Estudio a nivel nacional de la mortalidad materna intrahospitalaria en Ecuador, 2015-2022 / Estudo nacional sobre mortalidade materna intra-hospitalar no Equador, 2015-2022

ABSTRACT Objective. This study aimed to analyze estimates of in-hospital delivery-related maternal mortality and sociodemographic factors influencing this mortality in Ecuador during 2015 to 2022. Methods. Data from publicly accessible registries from the Ecuadorian National Institute of Statistics and Censuses were analyzed. Maternal mortality ratios (MMRs) were calculated, and bivariate and multivariate logistic regression models were used to obtain unadjusted and adjusted odds ratios. Results. There was an increase in in-hospital delivery-related maternal deaths in Ecuador from 2015 to 2022: MMRs increased from 3.70 maternal deaths/100 000 live births in 2015 to 32.22 in 2020 and 18.94 in 2022. Manabí province had the highest rate, at 84.85 maternal deaths/100 000 live births between 2015 and 2022. Women from ethnic minorities had a higher probability of in-hospital delivery-related mortality, with an adjusted odds ratio (AOR) of 9.59 (95% confidence interval [95% CI]: 6.98 to 13.18). More maternal deaths were also observed in private health care facilities (AOR: 1.99, 95% CI: 1.4 to 2.84). Conclusions. Efforts to reduce maternal mortality have stagnated in recent years. During the COVID-19 pandemic in 2020, an increase in maternal deaths in hospital settings was observed in Ecuador. Although the pandemic might have contributed to the stagnation of maternal mortality estimates, socioeconomic, demographic and clinical factors play key roles in the complexity of trends in maternal mortality. The results from this study emphasize the importance of addressing not only the medical aspects of care but also the social determinants of health and disparities in the health care system.

RESUMEN Objetivo. El objetivo de este estudio fue analizar las cifras estimadas de mortalidad materna intrahospitalaria asociada al parto y los factores sociodemográficos que influyen en ella en Ecuador en el período 2015-2022. Métodos. Se analizaron datos de los registros de acceso público del Instituto Nacional de Estadística y Censos de Ecuador. Se calcularon las razones de mortalidad materna (RMM) y se utilizaron modelos de regresión logística bivariados y multivariados para obtener los cocientes de posibilidades sin ajustar y ajustados. Resultados. Entre el 2015 y el 2022, se observó un aumento de las muertes maternas intrahospitalarias asociadas al parto en Ecuador: la RMM aumentó de 3,70 muertes maternas por 100 000 nacidos vivos en el 2015 a 32,22 en el 2020 y 18,94 en el 2022. En la provincia de Manabí se registró la cifra más alta, con 84,85 muertes maternas por 100 000 nacidos vivos entre el 2015 y el 2022. Las mujeres pertenecientes a minorías étnicas tuvieron una mayor probabilidad de muerte intrahospitalaria por causas relacionadas con el parto, con un cociente de posibilidades ajustado (aOR, por su sigla en inglés) de 9,59 (intervalo de confianza del 95% [IC del 95%]: 6,98 a 13,18). También se observó una mayor mortalidad materna en los establecimientos de salud privados (aOR: 1,99, IC del 95%: 1,4 a 2,84). Conclusiones. Los esfuerzos para reducir la mortalidad materna se han estancado en los últimos años. Durante la pandemia de COVID-19, se observó un aumento de las muertes maternas en el 2020 en entornos hospitalarios en Ecuador. Si bien la pandemia podría haber contribuido a que las cifras estimadas de mortalidad materna se estancaran, los factores socioeconómicos, demográficos y clínicos desempeñan un papel clave en la complejidad de las tendencias de la mortalidad materna. Los resultados de este estudio destacan la importancia de abordar no solo los aspectos médicos de la atención, sino también los determinantes sociales de la salud y las disparidades en el sistema de atención de salud.

RESUMO Objetivo. O objetivo deste estudo foi analisar estimativas de mortalidade materna relacionada ao parto intra-hospitalar e os fatores sociodemográficos que influenciaram esse tipo de mortalidade no período de 2015 a 2022 no Equador. Métodos. Foram analisados dados de registros de acesso público do Instituto Nacional de Estatísticas e Censos do Equador. Foram calculadas razões de mortalidade materna (RMM), com o uso de regressão logística bivariada e multivariada para obter razões de chance não ajustadas e ajustadas. Resultados. Houve um aumento nas mortes maternas relacionadas ao parto intra-hospitalar no Equador entre 2015 e 2022: as RMM aumentaram de 3,70 mortes maternas/100 mil nascidos vivos em 2015 para 32,22 em 2020 e 18,94 em 2022. A província de Manabí teve a taxa mais alta, com 84,85 mortes maternas/100 mil nascidos vivos entre 2015 e 2022. Mulheres de minorias étnicas tiveram maior probabilidade de mortalidade relacionada ao parto intra-hospitalar, com uma razão de chances ajustada (RCa) de 9,59 (intervalo de confiança de 95% [IC95%]: 6,98 a 13,18). Também foram observadas mais mortes maternas em estabelecimentos de saúde privados (RCa: 1,99, IC95%: 1,4 a 2,84). Conclusões. As inciativas para reduzir a mortalidade materna estagnaram nos últimos anos. Durante a pandemia de COVID-19 em 2020, foi observado um aumento nas mortes maternas em hospitais do Equador. Embora a pandemia possa ter contribuído para a estagnação das estimativas de mortalidade materna, fatores socioeconômicos, demográficos e clínicos desempenharam papéis fundamentais na complexidade das tendências de mortalidade materna. Os resultados deste estudo destacam a importância de abordar não apenas os aspectos clínicos da atenção, mas também os determinantes sociais da saúde e as disparidades do sistema de saúde.

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.

Efecto de la N-acetilcisteína en la mortalidad de pacientes ingresados por COVID-19: estudio de cohorte retrospectivo / Impact of N-Acetylcysteine in the mortality of patients hospitalized with COVID-19: a retrospective cohort study

Introducción y objetivo La N-acetilcisteína se ha propuesto para el tratamiento de COVID-19 gracias a sus efectos mucolítico, antioxidante y antiinflamatorio. El presente estudio tiene como objetivo evaluar su efecto en pacientes ingresados con COVID-19, en términos de mortalidad. Material y métodos Estudio de cohorte retrospectivo unicéntrico. Se incluyeron todos los pacientes ingresados por COVD-19 entre marzo y abril de 2020 en nuestro hospital. Resultados Un total de 378 pacientes fueron incluidos; de ellos, 196 (51,9%) fueron hombres, la edad media fue de 73,3±14,5 años. Un total de 199 (52,6%) pacientes recibieron tratamiento con N-acetilcisteína. Más del 70% tuvieron tos, fiebre y/o disnea. La mortalidad hospitalaria global fue del 26,7%. Un análisis multivariante mediante regresión logística identificó la edad de los pacientes [mayores de 80 años; OR: 8,4 (IC95%: 3-23,4)], una afectación radiológica moderada o grave medida por la escala RALE [OR: 7,3 (IC95%: 3,2-16,9)], el consumo de tabaco [OR: 2,8 (IC95%: 1,3-6,1)] y arritmia previa [OR: 2,8 (IC95%: 1,3-6,2)] como factores de riesgo que se asociaron independientemente con la mortalidad durante el ingreso. El tratamiento con N-acetilcisteína fue identificado como factor protector [OR: 0,57 (IC95%: 0,31-0,99)]. El asma podría representar asimismo un factor protector de mortalidad, aunque en el presente estudio no alcanza significación estadística [OR: 0,19 (IC95%: 0,03-1,06)]. Conclusiones Los pacientes con COVID-19 tratados con N-acetilcisteína presentaron una menor mortalidad y mejor evolución en nuestro estudio. Futuros estudios prospectivos o ensayos clínicos aleatorizados deben confirmar el papel de la N-acetilcisteína en pacientes con COVID-19 (AU)

Introduction and aim N-acetylcysteine has been proposed for the treatment of COVID-19 thanks to its mucolytic, antioxidant and anti-inflammatory effects. Our aim is to evaluate its effect on patients admitted with COVID-19 in mortality terms. Material and methods Retrospective single-center cohort study. All patients admitted to our hospital for COVID-19 from March to April 2020 have been considered. Results A total of 378 patients were included, being 196 (51.9%) men, with an average age of 73.3±14.5 years. The 52.6% (199) received treatment with N-acetylcysteine. More than 70% presented coughs, fever, and/or dyspnea. The global hospital mortality was 26.7%. A multivariate analysis through logistic regression identified the age of patients [older than 80; OR: 8.4 (95% CI: 3–23.4)], a moderate or severe radiologic affectation measured by the RALE score [OR: 7.3 (95% CI: 3.2–16.9)], the tobacco consumption [OR: 2.8 (95% CI: 1.3–6.1)] and previous arrhythmia [OR 2.8 (95% CI: 1.3–6.2)] as risk factor that were independently associated with mortality during the admission. The treatment with N-acetylcysteine was identified as a protective factor [OR: 0.57 (95% CI: 0.31–0.99)]. Asthma also seems to have a certain protective factor although it was not statistically significant in our study [OR: 0.19 (95% CI: 0.03–1.06)]. Conclusions Patients with COVID-19 treated with N-acetylcysteine have presented a lower mortality and a better evolution in this study. Future prospective studies or randomized clinical trials must confirm the impact of N-acetylcysteine on COVID-19 patients (AU)

Papel de las estatinas en la evolución clínica de los pacientes octogenarios ingresados por COVID-19 / Role of statins in clinical evolution of octogenarian patients admitted due to COVID-19

antecedentes y objetivos La coronavirus disease 2019 (COVID-19) produce una elevada mortalidad en pacientes ancianos. Algunos estudios han señalado un beneficio del tratamiento con estatinas en la evolución de esta enfermedad. El objetivo de este estudio es analizar la mortalidad intrahospitalaria en relación al tratamiento previo al ingreso con estatinas en una población de pacientes octogenarios, ya que no existen estudios específicamente en este grupo de población. Materiales y métodos Se realizó un estudio de cohortes retrospectivo unicéntrico incluyendo un total de 258 pacientes ≥80 años con ingreso hospitalario por COVID-19 confirmada, entre el 1 de marzo y el 31 de mayo de 2020. Se dividieron en dos grupos: toma de estatinas previas al ingreso (n = 129) o no (n=129). Resultados La mortalidad intrahospitalaria por COVID-19 en pacientes ≥ 80 años (86,13+-4,40) durante la primera ola fue del 35,7% (IC 95%:30 1-41,7%). La mortalidad de los pacientes que tomaban previamente estatinas fue del 25,6% mientras que la de aquellos que no las tomaban fue del 45,7%. El sexo femenino (RR 0,62 IC 95%[0,44-0,89]; p 0,008), la diabetes (RR 0,61 IC 95% [0,41-0,92];p 0,017) y el tratamiento previo al ingreso con estatinas (RR 0,58 IC 95% [0,41-0,83]; p 0,003) se asociaron a una menor mortalidad intrahospitalaria. La afectación pulmonar grave se asoció a un aumento de la mortalidad intrahospitalaria (RR 1,45 IC 95% [1,04-2,03]; p 0,028). La hipertensión arterial, la obesidad, la edad, la enfermedad cardiovascular y un mayor índice de Charlson no mostraron sin embargo influencia sobre la mortalidad intrahospitalaria. Conclusiones En pacientes octogenarios tratados con estatinas previo al ingreso por COVID-19 se observó una menor mortalidad intrahospitalaria en la primera ola (AU)

Introduction and objectives coronavirus disease 2019 (COVID-19) causes high mortality in elderly patients. Some studies have shown a benefit of statin treatment in the evolution of this disease. Since there are no similar publications in this population group, the aim of this study is to analyze in-hospital mortality in relation to preadmission treatment with statins in an exclusively elderly population of octogenarian patients. Materials and methods A single-center retrospective cohort study was performed including a total of 258 patients ≥80 years with hospital admission for confirmed COVID-19 between March 1 and May 31, 2020. They were divided into two groups: taking statins prior to admission (n=129) or not (n=129). Results In-hospital mortality due to COVID-19 in patients ≥80 years (86.13±4.40) during the first wave was 35.7% (95% CI: 30.1–41.7%). Mortality in patients previously taking statins was 25.6% while in those not taking statins was 45.7%. Female sex (RR 0.62 [0.44-0.89]; p=0.008), diabetes (RR 0.61 [0.41-0.92]; p=0.017) and pre-admission treatment with statins (RR 0.58 95% CI [0.41-0.83]; p=0.003) were associated with lower in-hospital mortality. Severe lung involvement was associated with increased in-hospital mortality (RR 1.45 95% CI [1.04-2.03]; p=0.028). Hypertension, obesity, age, cardiovascular disease and a higher Charlson index did not, however, show influence on in-hospital mortality. Conclusions In octogenarian patients treated with statins prior to admission for COVID-19 in the first wave, lower in-hospital mortality was observed (AU)

CONCLUSIONS: Patients with COVID-19 treated with N-acetylcysteine have presented a lower mortality and a better evolution in this study. Future prospective studies or randomized clinical trials must confirm the impact of N-Acetylcysteine on COVID-19 patients.

[Role of statins in clinical evolution of octogenarian patients admitted due to COVID-19]. / Papel de las estatinas en la evolución clínica de los pacientes octogenarios ingresados por COVID-19.

INTRODUCTION AND OBJECTIVES: coronavirus disease 2019 (COVID-19) causes high mortality in elderly patients. Some studies have shown a benefit of statin treatment in the evolution of this disease. Since there are no similar publications in this population group, the aim of this study is to analyze in-hospital mortality in relation to preadmission treatment with statins in an exclusively elderly population of octogenarian patients. MATERIALS AND METHODS: A single-center retrospective cohort study was performed including a total of 258 patients ≥80 years with hospital admission for confirmed COVID-19 between March 1 and May 31, 2020. They were divided into two groups: taking statins prior to admission (n=129) or not (n=129). RESULTS: In-hospital mortality due to COVID-19 in patients ≥80 years (86.13±4.40) during the first wave was 35.7% (95% CI: 30.1-41.7%). Mortality in patients previously taking statins was 25.6% while in those not taking statins was 45.7%. Female sex (RR 0.62 [0.44-0.89]; p=0.008), diabetes (RR 0.61 [0.41-0.92]; p=0.017) and pre-admission treatment with statins (RR 0.58 95% CI [0.41-0.83]; p=0.003) were associated with lower in-hospital mortality. Severe lung involvement was associated with increased in-hospital mortality (RR 1.45 95% CI [1.04-2.03]; p=0.028). Hypertension, obesity, age, cardiovascular disease and a higher Charlson index did not, however, show influence on in-hospital mortality. CONCLUSIONS: In octogenarian patients treated with statins prior to admission for COVID-19 in the first wave, lower in-hospital mortality was observed.

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

Delay of surgical treatment of severe tricuspid regurgitation and outcomes in patients with left-sided heart valve disease.

INTRODUCTION AND OBJECTIVES: The influence of the delay between diagnosis and surgery in severe tricuspid regurgitation (TR) remains controversial. We aimed to analyze the association between delay to surgery and operative and mid-term mortality in patients with severe TR concomitant to left-valve surgery. METHODS: We conducted an observational retrospective study analyzing risk factors in patients undergoing left-valve surgery concomitant with severe TR. The clinical and demographic variables were prospectively collected. The time of first diagnosis of TR was retrospectively collected. RESULTS: A total of 253 patients were analyzed. TR was functional in 82.6%. The median latency between diagnosis and surgery was 24 months. Operative mortality was 12.2%. On multivariate analysis, higher operative mortality was associated with older age, worse preoperative NYHA functional class, triple valve surgery, hyponatremia, and anemia. The median follow-up was 35 months. Survival at 1 and 5 years was 85.2% and 73.7%, respectively. Mortality during follow-up was associated with male sex, preoperative massive TR, and longer latency between diagnosis and surgery. CONCLUSIONS: The variables related to worse preoperative functional class were associated with increased operative mortality. Lower mid-term survival was associated with longer latency between diagnosis of severe TR and surgery, massive preoperative TR, and older age.

Desigualdade racial na assistência à saúde do adulto internado por COVID-19 / Desigualdad racial en la atención a la salud de adultos hospitalizados por COVID-19 / Racial inequality in health care of adults hospitalized with COVID-19

Resumo: O objetivo deste artigo foi analisar a associação entre raça/cor e assistência à saúde, em adultos hospitalizados pela síndrome respiratória aguda grave (SRAG)/COVID-19 no Brasil, entre março de 2020 e setembro de 2022. Trata-se de estudo transversal, que utilizou o banco de dados do Sistema de Informação de Vigilância Epidemiológica da Gripe (SIVEP-Gripe) e contou com uma população composta por adultos (≥ 18 anos). A classificação final foi SRAG por COVID-19 ou SRAG não especificada. O efeito direto do aspecto cor na mortalidade intra-hospitalar foi estimado por meio de regressão logística ajustada por idade, sexo, escolaridade, sistema de saúde e período, estratificado por situação vacinal. Esse mesmo modelo foi utilizado também para avaliar o efeito do quesito cor nas variáveis de acesso aos serviços de saúde: unidade de terapia intensiva (UTI), tomografia, radiografia de tórax e suporte ventilatório. Os resultados evidenciam que pretos, pardos e indígenas morreram mais, independentemente do grau de escolaridade e da quantidade de comorbidades, com maiores chances de óbito em 23%, 32% e 80%, respectivamente, ao serem submetidos ao suporte ventilatório. Foram observadas diferenças raciais no uso de serviços de saúde e nos desfechos de morte por COVID-19 ou SRAG não especificada, em que minorias étnicas tiveram maiores taxas de mortalidade intra-hospitalar e os recursos hospitalares foram utilizados com menos frequência. Tais resultados sugerem que as populações negra e indígena têm severas desvantagens em relação à branca, enfrentando barreiras de acesso aos serviços de saúde no contexto da pandemia de COVID-19.

Resumen: Se pretende analizar la asociación entre raza/color en la atención de la salud de adultos hospitalizados por síndrome respiratorio agudo severo (SARS)/COVID-19 en el período entre marzo de 2020 y septiembre de 2022, tomando Brasil como unidad de análisis. Se trata de un estudio transversal, en que se utilizó la base de datos del Sistema de Información de Vigilancia Epidemiológica de la Gripe (SIVEP-Gripe) y tuvo una muestra compuesta por adultos (≥ 18 años) y la clasificación final fue SARS por COVID-19 o SARS no especificado. El efecto directo de la pregunta color sobre la mortalidad intrahospitalaria se estimó mediante la regresión logística ajustada según edad, sexo, nivel de estudios, sistema de salud y período, estratificada por estado de vacunación. Este modelo también se utilizó para evaluar el efecto de la pregunta color en las variables de acceso a los servicios de salud: unidades de cuidado intensivo (UCI), tomografía, radiografía de tórax y soporte ventilatorio. Los resultados muestran que negros, pardos e indígenas murieron más, independientemente del nivel de estudios y el número de comorbilidades, y cuando fueron sometidos a soporte ventilatorio, tuvieron mayores probabilidades de muerte con el 23%, 32% y 80%, respectivamente. Se observaron diferencias raciales en el uso de los servicios de salud y los resultados de muerte por COVID-19 o SARS no especificado, en los que las minorías étnicas tuvieron una mayor mortalidad intrahospitalaria y los recursos hospitalarios se utilizaron con menos frecuencia. Estos resultados evidencian que las poblaciones negra e indígena tienen graves desventajas en comparación con la población blanca, afrontando dificultades de acceso a los servicios de salud en el contexto de la pandemia del COVID-19.

Abstract: The objective was to analyze the association of race/skin color in health care, in adults hospitalized with severe acute respiratory syndrome (SARS)/COVID-19, between March 2020 and September 2022, with Brazil as the unit of analysis. This is a cross-sectional study that used the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) database and had a population composed of adults (≥ 18 years) and the final classification was SARS by COVID-19 or unspecified SARS. The direct effect of skin color on in-hospital mortality was estimated through logistic regression adjusted for age, gender, schooling level, health care system and period, stratified by vaccination status. This same model was also used to assess the effect of skin color on the variables related to access to health care services: intensive care unit (ICU), tomography, chest X-ray and ventilatory support. The results show that black, brown and indigenous people died more, regardless the schooling level and number of comorbidities, with 23%, 32% and 80% higher chances of death, respectively, when submitted to ventilatory support. Racial differences were observed in the use of health care services and in outcomes of death from COVID-19 or unspecified SARS, in which ethnic minorities had higher in-hospital mortality and lower use of hospital resources. These results suggest that black and indigenous populations have severe disadvantages compared to the white population, facing barriers to access health care services in the context of the COVID-19 pandemic.

A competing risk survival analysis of the sociodemographic factors of COVID-19 in-hospital mortality in Ecuador / Un análisis de supervivencia de riesgos competitivos de los factores sociodemográficos de la mortalidad intrahospitalaria por COVID-19 en Ecuador / Uma análise concorrente de sobrevida de risco dos fatores sociodemográficos da mortalidade intra-hospitalar por COVID-19 no Equador

This study aimed to analyze the effect of sociodemographic characteristics on COVID-19 in-hospital mortality in Ecuador from March 1 to December 31, 2020. This retrospective longitudinal study was performed with data from publicly accessible registries of the Ecuadorian National Institute of Statistics and Censuses (INEC). Data underwent a competing risk analysis with estimates of the cumulative incidence function (CIF). The effect of covariates on CIFs was estimated using the Fine-Gray model and results were expressed as adjusted subdistribution hazard ratios (SHR). The analysis included 30,991 confirmed COVID-19 patients with a mean age of 56.57±18.53 years; 60.7% (n = 18,816) were men and 39.3% (n = 12,175) were women. Being of advanced age, especially older than or equal to 75 years (SHR = 17.97; 95%CI: 13.08-24.69), being a man (SHR = 1.29; 95%CI: 1.22-1.36), living in rural areas (SHR = 1.18; 95%CI: 1.10-1.26), and receiving care in a public health center (SHR = 1.64; 95%CI: 1.51-1.78) were factors that increased the incidence of death from COVID-19, while living at an elevation higher than 2,500 meters above sea level (SHR = 0.69; 95%CI: 0.66-0.73) decreased this incidence. Since the incidence of death for individuals living in rural areas and who received medical care from the public sector was higher, income and poverty are important factors in the final outcome of this disease.

Este estudio tuvo como objetivo analizar el efecto de las características sociodemográficas en la mortalidad intrahospitalaria de los pacientes con COVID-19 confirmado en Ecuador entre el 1 de marzo y el 31 de diciembre de 2020. Se trató de un estudio longitudinal retrospectivo realizado con datos extraídos de registros de acceso público reportados por el Instituto Nacional de Estadística y Censos (INEC) de Ecuador. Los datos se analizaron empleando un enfoque de riesgo competitivo, utilizando estimaciones de la función de incidencia acumulada (FIA). El efecto de las covariables sobre las FIA se estimó mediante el modelo de Fine-Gray, y los resultados se expresaron como cocientes de riesgos de subdistribución (CRS) ajustados. El análisis incluyó 30.991 casos confirmados de COVID-19 con una edad media de 56,57±18,53 años; el 60,7% (n = 18.816) eran hombres y el 39,3% (n = 12.175) mujeres. Los factores que aumentaron la incidencia de muerte por COVID-19 fueron una edad avanzada, con mayor riesgo para los mayores o iguales a 75 años (CRS = 17,97; IC95%: 13,08-24,69); ser hombre (CRS = 1,29; IC95%: 1,22-1,36); residir en zonas rurales (CRS = 1,18; IC95%: 1,10-1,26); y recibir atención en un centro sanitario público (CRS = 1,64; IC95%: 1,51-1,78); mientras que un factor que disminuyó la incidencia de muerte fue residir en altitudes superiores a los 2.500 metros sobre el nivel del mar (CRS = 0,69; IC95%: 0,66-0,73). La mayor incidencia de muerte entre los que residían en zonas rurales y los que recibían atención médica del sector público sugiere que los ingresos y la pobreza son factores importantes en el desenlace final de esta enfermedad.

O objetivo deste estudo foi analisar o efeito de características sociodemográficas sobre a mortalidade intra-hospitalar de pacientes com COVID-19 confirmada no Equador, entre 1º de março e 31 de dezembro de 2020. Este é um estudo longitudinal e retrospectivo desenvolvido com dados extraídos de registros de acesso público declarados pelo Instituto Nacional de Estatística e Censos do Equador (INEC). Os dados foram analisados usando uma abordagem de risco concorrente com estimativas da função de incidência cumulativa (FIC). O efeito das covariáveis sobre as FICs foi estimado pelo modelo de Fine-Gray e os resultados expressos em índices de risco de subdistribuição (IRS) ajustados. A análise incluiu 30.991 casos confirmados da COVID-19 em pacientes com idade média de 56,57±18,53 anos; sendo 60,7% (n = 18.816) do sexo masculino e 39,3% (n = 12.175) do sexo feminino. Os fatores que aumentaram a incidência de óbitos por COVID-19 foram idade avançada, com maior risco para aqueles com 75 anos ou mais (IRS = 17,97; IC95%: 13,08-24,69); ser do sexo masculino (IRS = 1,29; IC95%: 1,22-1,36); residir em áreas rurais (IRS = 1,18; IC95%: 1,10-1,26); e receber atendimento em unidade pública de saúde (IRS = 1,64; IC95%: 1,51-1,78); ao passo que um fator que diminuiu a incidência de óbitos foi residir em altitudes superiores a 2.500 metros acima do nível do mar (IRS = 0,69; IC95%: 0,66-0,73). A maior incidência de óbitos naqueles que residiam em áreas rurais e que receberam atendimento médico do setor público sugere que a renda e a pobreza são fatores importantes no desfecho dessa doença.

Mortalidade por covid-19 no interior e em regiões metropolitanas do Brasil, 2020 a 2021 / COVID-19 mortality in metropolitan areas vs. other regions of Brazil, 2020 to 2021 / Mortalidad por COVID-19 en las regiones metropolitanas y en el interior de Brasil, 2020-2021

RESUMO Objetivo. Comparar as taxas de mortalidade hospitalar (TMH) por síndrome respiratória aguda grave (SRAG) associada à covid-19 registradas em regiões metropolitanas e no interior do Brasil em 2020 e 2021. Método. Trata-se de um estudo ecológico com dados públicos disponíveis no OpenDataSUS. As informações foram acessadas em maio de 2022. Consideraram-se as seguintes variáveis: idade, sexo, internação hospitalar, presença de fator de risco, internação em UTI, uso de suporte ventilatório e classificação final na ficha de registro individual de casos de SRAG por covid-19. Os casos e óbitos foram estratificados em cinco faixas etárias (0-19 anos, 20-39 anos, 40-59 anos, 60-79 anos e ≥80 anos) e por localização do município de residência (região metropolitana ou interior). A TMH teve como numerador o número absoluto de óbitos por SRAG associada à covid-19; e, como denominador, o número absoluto de casos de SRAG por covid-19 segundo ano de ocorrência, residência em região metropolitana ou interior, faixa etária, sexo, internação hospitalar, presença de fator de risco, internação em unidade de terapia intensiva (UTI) e uso de suporte ventilatório. Resultados. Verificou-se aumento significativo da TMH por SRAG associada à covid-19 em 2021 em todos os grupos etários, exceto 0-19 anos e ≥80 anos, assim como entre indivíduos internados em UTI e que utilizaram suporte ventilatório invasivo, tanto nas regiões metropolitanas quanto no interior. Conclusões. Houve piora do cenário epidemiológico em 2021 com o aumento da TMH, mas não foram identificadas diferenças entre as regiões metropolitanas e o interior do país.

ABSTRACT Objective. To compare hospital mortality rates (HMR) due to severe acute respiratory syndrome (SARS) associated with COVID-19 recorded in metropolitan areas and other regions (interior) of Brazil in 2020 and 2021. Method. This ecological study used public data available on OpenDataSUS. The information was accessed in May 2022. The following variables were considered: age, sex, hospitalization, presence of a risk factor, ICU stay, use of ventilatory support, and final classification in the individual registration form of SARS cases due to COVID-19. Cases and deaths were stratified into five age groups (0-19 years, 20-39 years, 40-59 years, 60-79 years, and ≥80 years) and by place of residence (metropolitan area or interior). The HMR had as numerator the absolute number of deaths by SARS associated with covid-19; and, as a denominator, the absolute number of cases of SARS due to covid-19 according to the year of occurrence, area of residence, age bracket, sex, hospitalization, presence of a risk factor, ICU admission, and use of ventilatory support. Results. There was a significant increase in HMR due to SARS associated with COVID-19 in 2021 in all age groups, except 0-19 years and ≥80 years, as well as among individuals admitted to an ICU and who used invasive ventilatory support, both in metropolitan areas as well as in the interior. Conclusions. There was a worsening of the epidemiological scenario in 2021 with an increase in HMR. However, no differences were identified between the metropolitan regions and the interior of the country.

Upper respiratory tract viral load quantification in COVID-19 patients at hospital admission and its association with disease severity.

INTRODUCTION: There are aspects of COVID-19 pathogenesis that are still unknown. OBJECTIVE: To determine the relationship between severity, mortality and viral replication in patients with COVID-19. METHODS: Clinical characteristics, severity and mortality of 203 patients hospitalized for COVID-19 were analyzed and correlated with viral load (VL) and threshold cycle (TC) at admission; nasopharyngeal swab was obtained. RESULTS: Mean VLs in surviving patients with mild to moderate, moderate to severe and severe disease were the following: 6.8 x 106, 7.6 x 107 and 1.0 x 109, respectively; and in patients with critical disease who died, VL was 1.70 x 109. TCs were 26.06, 24.07, 22.66 and 21.78 for the same groups. In those who died, a higher mean VL was observed at admission in comparison with those who survived (1.7 x 109 vs. 9.84 x 106; p < 0.001). A significant correlation was observed between VL, severity and death (r = 0.254, p < 0.045 and r = 0.21, p < 0.015). High VL was associated with increased in-hospital mortality in comparison with low VL (OR = 2.926, p < 0.017). CONCLUSION: SARS-CoV-2 VL determined at hospital admission might classify risk simultaneously with other factors described in COVID-19.

INTRODUCCIÓN: Aún se desconocen aspectos de la patogenia de COVID-19. OBJETIVO: Determinar la relación entre gravedad, mortalidad y replicación viral en pacientes con COVID-19. MÉTODOS: Se analizaron características clínicas, gravedad de la enfermedad y mortalidad de 203 pacientes hospitalizados por COVID-19 y se correlacionaron con carga viral (CV) y ciclo umbral (Ct) al ingreso; se tomó hisopado nasofaríngeo. RESULTADOS: Las CV medias en los pacientes sobrevivientes fueron las siguientes ante enfermedad leve a moderada, moderada a grave y grave: 6.8 × 106, 7.6 × 107 y 1.0 × 109; y en los pacientes con enfermedad crítica que fallecieron, la CV fue de 1.70 × 109. Los Ct fueron 26.06, 24.07, 22.66 y 21.78 para esos mismos grupos. En quienes fallecieron se observó mayor CV media al ingreso en comparación con quienes sobrevivieron (1.7 × 109 versus 9.84 × 106), p < 0.001. Se evidenció correlación significativa entre CV, gravedad y muerte (r = 0.254, p < 0.045 y r = 0.21, p < 0.015). La CV alta se asoció a mayor mortalidad intrahospitalaria en comparación con la CV baja (RM = 2.926, p < 0.017). CONCLUSIÓN: La CV de SARS-CoV-2 determinada al ingreso hospitalario podría calificar el riesgo simultáneamente con otros factores descritos en COVID-19.

Factors associated with mortality in critically ill patients with COVID-19 / Fatores associados à mortalidade em pacientes críticos com COVID-19 / Factores asociados a la mortalidad en pacientes críticos con COVID-19

Background and objectives: COVID-19 is a life-threatening disease. Recognizing the main characteristics of the disease and its main complications will help future interventions, care, and management of health services since territorial and population diversities directly influence health outcomes. Our main objective is to describe the clinical characteristics, outcomes, and factors associated with mortality of patients with COVID-19 admitted to the intensive care unit of a public and tertiary hospital. Methods: Cohort study, conducted from March 1 to September 30, 2020. Poisson regression was performed to investigate the variables of hospital treatment as potential risk factors for in-hospital mortality. Results: Of the 283 eligible patients in this study, the hospital mortality rate was of 41.7% (n=118). The most common outcomes were acute respiratory distress syndrome, nosocomial infection, and septic shock. Factors independently associated with increased risk of death were age greater than 51 years old (RR=1.7, 95%CI=1.0-2.8), especially over 70 years old (RR=2.9, 95%CI=1.7-2.8), current smoker (RR=1.8, 95%CI=1.1-2.9), requiring the use of inotrope (RR=1.4, 95%CI=1.0-2.0), and presenting potassium greater than 5.0 mEq/l on admission (RR=1.3, 95%CI=1.0-1.7). Conclusion: Mortality was associated with older age, being a current smoker, inotrope use, and presenting potassium greater than 5.0 on hospital admission.(AU)

Justificativa e objetivos: A COVID-19 é uma doença ameaçadora à vida. Reconhecer as características da doença e suas principais complicações nesta população auxiliará em futuras intervenções, cuidados e gestão dos serviços de saúde, uma vez que a diversidade territorial e populacional influencia diretamente nos resultados de saúde. O objetivo principal do presente estudo é descrever as características clínicas, desfechos e fatores associados à mortalidade de pacientes com COVID-19 internados na unidade de terapia intensiva de um hospital público e terciário. Métodos: Estudo de coorte, realizado de 1º de março a 30 de setembro de 2020. Foi realizada regressão de Poisson para investigar variáveis de apresentação hospitalar como potenciais fatores de risco para mortalidade intra-hospitalar. Resultados: Dos 283 pacientes elegíveis neste estudo, o dado de mortalidade hospitalar foi de 41,7% (n=118). Os desfechos mais comuns foram síndrome do desconforto respiratório agudo, infecção hospitalar e choque séptico. Os fatores independentemente associados ao aumento do risco de morte foram idade superior a 51 anos (RR=1,7, IC 95%=1,0-2,8), principalmente acima de 70 anos (RR=2,9, IC 95%=1,7-2,8), tabagismo atual (RR=1,8, IC 95%=1,1-2,9), necessidade de inotrópico (RR=1,4, IC 95%=1,0-2,0) e potássio maior que 5,0 mEq/l (RR=1,3, IC 95%=1,0- 1.7) na admissão. Conclusão: A mortalidade esteve associada à idade avançada, tabagismo atual, uso de inotrópicos e potássio maior que 5,0 na admissão hospitalar.(AU)

Justificación y objetivos: La COVID-19 es una enfermedad potencialmente mortal. Reconocer las características de la enfermedad y sus principales complicaciones en esta población ayudará a futuras intervenciones, atención y gestión de los servicios de salud, ya que las diversidades territoriales y poblacionales influyen directamente en los resultados de salud. El objetivo principal de este estudio es describir las características clínicas, los resultados y los factores asociados a la mortalidad de los pacientes con COVID-19 ingresados en la unidad de cuidados intensivos de un hospital público y de tercer nivel. Métodos: Estudio de cohorte, realizado del 1 de marzo al 30 de septiembre de 2020. Se realizó regresión de Poisson para investigar variables en la presentación hospitalaria como potenciales factores de riesgo para la mortalidad intrahospitalaria. Resultados: De los 283 pacientes elegibles en este estudio, el 41,7% (n=118) tuvo mortalidad hospitalaria. Los desenlaces más comunes fueron síndrome de dificultad respiratoria aguda, infección nosocomial y shock séptico. Los factores independientemente asociados a mayor riesgo de muerte fueron edad mayor de 51 años (RR=1,7, IC95%=1,0-2,8), especialmente mayores de 70 años (RR=2,9, IC95%=1,7-2,8), tabaquismo actual (RR=1,8, IC95%=1,1-2,9), necesidad de inotrópico (RR=1,4, IC95%=1,0-2,0) y potasio mayor que 5,0 mEq/l (RR=1,3, IC95%=1,0-1,7). Conclusión: La mortalidad estuvo asociada a la edad avanzada, tabaquismo actual, uso de inotrópico y potasio mayor a 5,0 en la admisión hospitalaria.(AU)

Epidemiología y mortalidad hospitalaria por evento vascular cerebral en un hospital de la Ciudad de México: estudio prospectivo de 2 años.

OBJECTIVE: To describe patient characteristics, case fatality rate, and assess predictors of in-hospital acute ischemic (IS) or hemorrhagic stroke (HS) mortality. METHOD: Adult patients with confirmed stroke were recruited from January 1st, 2018 to December 31st, 2019.Data collect included demographic and laboratory characteristics, risk factors, and clinical outcome. A binary logistic regression model with relative risk and 95% confidence interval was performed. RESULTS: A total of 172 patients were recruited; IS was present in 78.5% of patients. The mean of age was 75.27 ± 11.44 years in IS group and 71.62 ± 11.72 years in HS group. Hypertension was present in > 70% of patients in both groups; the in-hospital case fatality rate was 15.5% for IS and 21.5% for HS. Severe NIHSS score (> 13) was significantly associated with in-hospital mortality in both stroke types. CONCLUSIONS: Hypertension was the most common risk factor in patients with stroke. The in-hospital case fatality rate was lower to previously reported in Mexico. Nevertheless, it remains high compared to reported in developed countries. NIHSS scale was the strongest predictor of mortality. There is a need to develop more effective stroke management services in Mexico.

OBJETIVO: Describir las características y los factores pronósticos para mortalidad intrahospitalaria en pacientes con diagnóstico de evento vascular cerebral isquémico (EVCi) o hemorrágico (EVCh). MÉTODO: Se incluyeron 172 pacientes en el periodo del 1 de enero de 2018 al 31 de diciembre de 2019. Se recabaron características demográficas, de laboratorio y factores de riesgo. Se realizó un análisis de regresión logística binaria calculando el riesgo relativo y el intervalo de confianza al 95% para identificar las variables asociadas a la mortalidad. RESULTADOS: El 78.5% de los pacientes presentaron EVCi. La media de edad fue de 75.27 ± 11.44 años en el EVCi y de 71.62 ± 11.72 años en el EVCh. El antecedente de hipertensión se encontró en más del 70% de los pacientes en ambos tipos de EVC. La mortalidad hospitalaria fue del 15.5% en el EVCi y del 21.5% en el EVCh. Una puntuación grave (> 13) en la escala NIHSS (National Institutes of Health Stroke Scale) presentó asociación significativa con la mortalidad en ambos tipos de EVC. CONCLUSIONES: La hipertensión fue el factor de riesgo más común. La mortalidad hospitalaria fue menor que lo reportado previamente en México. La escala NIHSS fue el mejor predictor de mortalidad. Es necesario desarrollar estrategias para mejorar la atención de los pacientes con EVC en México.

Cuantificación de la carga viral en el tracto respiratorio superior en pacientes con COVID-19 al ingreso hospitalario y su asociación con la gravedad de la enfermedad / Upper respiratory tract viral load quantification in COVID-19 patients at hospital admission and its association with disease severity

Resumen Introducción: Aún se desconocen aspectos de la patogenia de COVID-19. Objetivo: Determinar la relación entre gravedad, mortalidad y replicación viral en pacientes con COVID-19. Métodos: Se analizaron características clínicas, gravedad de la enfermedad y mortalidad de 203 pacientes hospitalizados por COVID-19 y se correlacionaron con carga viral (CV) y ciclo umbral (Ct) al ingreso; se tomó hisopado nasofaríngeo. Resultados: Las CV medias en los pacientes sobrevivientes fueron las siguientes ante enfermedad leve a moderada, moderada a grave y grave: 6.8 × 106, 7.6 × 107 y 1.0 × 109; y en los pacientes con enfermedad crítica que fallecieron, la CV fue de 1.70 × 109. Los Ct fueron 26.06, 24.07, 22.66 y 21.78 para esos mismos grupos. En quienes fallecieron se observó mayor CV media al ingreso en comparación con quienes sobrevivieron (1.7 × 109 versus 9.84 × 106), p < 0.001. Se evidenció correlación significativa entre CV, gravedad y muerte (r = 0.254, p < 0.045 y r = 0.21, p < 0.015). La CV alta se asoció a mayor mortalidad intrahospitalaria en comparación con la CV baja (RM = 2.926, p < 0.017). Conclusión: La CV de SARS-CoV-2 determinada al ingreso hospitalario podría calificar el riesgo simultáneamente con otros factores descritos en COVID-19.

Abstract Introduction: There are aspects of COVID-19 pathogenesis that are still unknown. Objective: To determine the relationship between severity, mortality and viral replication in patients with COVID-19. Methods: Clinical characteristics, severity and mortality of 203 patients hospitalized for COVID-19 were analyzed and correlated with viral load (VL) and threshold cycle (TC) at admission; nasopharyngeal swab was obtained. Results: Mean VLs in surviving patients with mild to moderate, moderate to severe and severe disease were the following: 6.8 × 106, 7.6 × 107 and 1.0 × 109, respectively; and in patients with critical disease who died, VL was 1.70 × 109. TCs were 26.06, 24.07, 22.66 and 21.78 for the same groups. In those who died, a higher mean VL was observed at admission in comparison with those who survived (1.7 × 109 vs 9.84 × 106; p < 0.001). A significant correlation was observed between VL, severity and death (r = 0.254, p < 0.045 and r = 0.21, p < 0.015). High VL was associated with increased in-hospital mortality in comparison with low VL (OR = 2.926, p < 0.017). Conclusion: SARS-CoV-2 VL determined at hospital admission might classify risk simultaneously with other factors described in COVID-19.

Hospital outcomes in patients evaluated by rheumatology in a Colombian historical cohort

Introduction: Hospitalized patients with systemic autoimmune rheumatic diseases (SARDs) generate high impact in clinical terms. Objectives: To characterize the study population and estimate risk factors associated with the presence of adverse outcomes in hospitalized patients consulting rheumatology at Clínica Imbanaco between January 2013 and December 2019. Methods: We analyzed a historical cohort of hospitalized patients who were evaluated by rheumatology. The population was classified as follows: group 1, patients with new onset diagnosed SARDs; group 2, patients with known diagnosed SARDs; group 3, patients without diagnosed SARDs; and group 4, patients with unconfirmed suspicion of SARDs. A composite adverse outcome was defined if at least one of the following occurred: (1) hospital mortality, (2) admission to the intensive care unit, (3) hospital infection, or (4) readmission. Results: Information was collected from 327 hospitalization events (307 patients). The median age was 48 (34-63) years and 222 (72.3%) were women. The composite adverse outcome occurred in 136 (41.5%) hospitalization events. Group 2 had the highest number of adverse outcomes (61/128; 47.6%). The variables associated with the worst outcomes were cardiovascular diagnosis at admission (OR = 4.63; CI: 1.60-13.43; p = 0.005), longer hospital stay (OR = 1.04; CI: 1.01-1.07; p = 0.005), and a treating specialty other than internal medicine (OR = 2.79; CI: 1.26-6.17; p = 0.011). Male sex (OR = 0.29; CI: 0.12-0.66; p = 0.004), having special health coverage (OR = 0.39; CI: 0.15-.099; p = 0.047), and hemoglobin > 11.4 g/dL (OR = 0.82; CI: 0.69-0.99; p = 0.039) were the factors associated with lower odds of developing the composite outcome. Conclusions: In this historical cohort, the group of patients with known diagnosed SARDs presented a higher number in percentage terms of adverse outcomes. The most frequent adverse outcomes were admission to the ICU and hospital readmission.

Introducción: Los pacientes hospitalizados con enfermedades reumáticas o autoinmunes sistémicas (ERAS) generan gran impacto en términos clínicos. Objetivos: Caracterizar a la población y estimar factores de riesgo asociados con la presencia de desenlaces adversos en pacientes evaluados hospitalariamente por reumatología en la Clínica Imbanaco durante los arios 2013-2019. Metodología: Se analizó una cohorte histórica de pacientes hospitalizados que fueron evaluados por reumatología. La población se clasificó así: grupo 1, pacientes con ERAS diagnosticada de novo; grupo 2, pacientes con ERAS diagnosticada conocida; grupo 3, pacientes sin ERAS diagnosticada; y grupo 4, pacientes con sospecha no confirmada de ERAS. Se definió un desenlace adverso compuesto si se presentó al menos uno de los siguientes casos: 1) mortalidad hospitalaria; 2) ingreso a la unidad de cuidado intensivo; 3) infección intrahospitalaria; 4) reingreso. Resultados: En un total de 327 eventos de hospitalización (307 pacientes), la mediana de edad fue 48 (34-63) años y 222 (72,3%) fueron mujeres. El desenlace adverso compuesto se presentó en 136 (41,5%) eventos. El grupo 2 tuvo mayor número de desenlaces adversos (61/128; 47,6%). Las variables asociadas con peores resultados fueron: diagnóstico inicial cardiovascular (OR = 4,63; IC: 1,60-13,43; p = 0,005), mayor estancia hospitalaria (OR = 1,04; IC: 1,01-1,07; p = 0,005) y tener una especialidad tratante diferente a medicina interna (OR = 2,79; IC: 1,266,17; p = 0,011). El sexo masculino (OR = 0,29; IC: 0,12-0,66; p = 0,004), pertenecer a un régimen especial de salud (OR = 0,39; IC: 0,15-0,99; p = 0,047) y tener hemoglobina > 11,4 g/dL (OR = 0,82; IC: 0,69-0,99; p = 0,039) fueron factores asociados con menor oportunidad de desarrollar el desenlace compuesto. Conclusiones: En esta cohorte histórica se encontró que porcentualmente el grupo de pacientes con ERAS diagnosticadas conocidas presentó mayor número de desenlaces adversos, entre los que se destacan para el mismo grupo, el ingreso a UCI y el reingreso hospitalario.
