Impacto de la edad, las comorbilidades y las complicaciones en pacientes con COVID-19 con síndrome de dificultad respiratoria aguda en la ventilación mecánica invasiva. Estudio multicéntrico observacional / Impact of Age, Comorbidities and Complications in COVID-19 Patients with Acute Respiratory Distress Syndrome on Invasive Mechanical Ventilation. An Observational Multicenter Study

Objetivos: Millones de pacientes con COVID-19 fueron internados en terapia intensiva en el mundo, la mitad desarrollaron síndrome de dificultad respiratoria aguda (SDRA) y recibieron ventilación mecánica invasiva (VMI), con una mortalidad del 50%. Analiza-mos cómo edad, comorbilidades y complicaciones, en pacientes con COVID-19 y SDRA que recibieron VMI, se asociaron con el riesgo de morir durante su hospitalización.Métodos: Estudio de cohorte observacional, retrospectivo y multicéntrico realizado en 5 hospitales (tres privados y dos públicos universitarios) de Argentina y Chile, durante el segundo semestre de 2020.Se incluyeron pacientes >18 años con infección por SARS-CoV-2 confirmada RT-PCR, que desarrollaron SDRA y fueron asistidos con VMI durante >48 horas, durante el se-gundo semestre de 2020. Se analizaron los antecedentes, las comorbilidades más fre-cuentes (obesidad, diabetes e hipertensión), y las complicaciones shock, insuficiencia renal aguda (IRA) y neumonía asociada a la ventilación mecánica (NAV), por un lado, y las alteraciones de parámetros clínicos y de laboratorio registrados.Resultados: El 69% era varón. La incidencia de comorbilidades difirió para los diferentes grupos de edad. La mortalidad aumentó significativamente con la edad (p<0,00001). Las comorbilidades, hipertensión y diabetes, y las complicaciones de IRA y shock se asociaron significativamente con la mortalidad. En el análisis multivariado, sólo la edad mayor de 60 años, la IRA y el shock permanecieron asociados con la mortalidad. Conclusiones: El SDRA en COVID-19 es más común entre los mayores. Solo la edad >60 años, el shock y la IRA se asociaron a la mortalidad en el análisis multivariado.

Objectives: Millions of patients with COVID-19 were admitted to intensive care world-wide, half developed acute respiratory distress syndrome (ARDS) and received invasive mechanical ventilation (IMV), with a mortality of 50%. We analyzed how age, comor-bidities and complications in patients with COVID-19 and ARDS who received IMV were associated with the risk of dying during their hospitalization.Methods: Observational, retrospective and multicenter cohort study carried out in 5 hospitals (three private and two public university hospitals) in Argentina and Chile, during the second half of 2020.Patients >18 years of age with SARS-CoV-2 infection confirmed by RT-PCR, who devel-oped ARDS and were assisted with IMV for >48 hours, during the second half of 2020, were included. History, the most frequent comorbidities (obesity, diabetes and hyper-tension) and the complications of shock, acute renal failure (AKI) and pneumonia as-sociated with mechanical ventilation (VAP), on the one hand, and the alterations of re-corded clinical and laboratory parameters, were analyzed.Results: 69% were men. The incidence of comorbidities differed for different age groups. Mortality increased significantly with age (p<0.00001). Comorbidities, hyper-tension and diabetes, and complications of ARF and shock were significantly associat-ed with mortality. In the multivariate analysis, only age over 60 years, ARF and shock remained associated with mortality.Conclusions: ARDS in COVID-19 is more common among the elderly. Only age >60 years, shock and ARF were associated with mortality in the multivariate analysis

Comportamiento de características seleccionadas en pacientes hospitalizados por neumonía adquirida en la comunidad y algunas asociaciones de interés práctico / Behavior of selected characteristics in patients hospitalized for community-acquired pneumonia and some associations of practical interest

La neumonía adquirida en la comunidad constituye una de las afecciones respiratorias que provoca más demanda de asistencia médica, y es responsable del mayor número de fallecidos por enfermedades infecciosas en Cuba. El objetivo del estudio ha sido determinar el comportamiento de características seleccionadas en pacientes hospitalizados por neumonía y precisar la existencia de asociaciones entre algunas de estas características.Se realizó un estudio observacional, con diseño descriptivo, que incluyó 1,809 pacientes hospitalizados por neumonía entre enero de 2012 y febrero de 2020. Fueron analizadas características relacionadas con las condiciones de base, clínico-radiológicas, y relativas al manejo y la evolución, mediante análisis bivariante y multivariante (regresión logística). La serie estuvo constituida fundamentalmente por pacientes ancianos (79%), mientras que el 20% presentaba la condición de encamamiento. Esta condición se asoció significativamente con el estado de demencia avanzada (OR 7,6[5,5;10,4]), y fue determinante en la presentación "solapada" del proceso (OR 1,5[1,09;2]). La presentación "solapada" de la neumonía estuvo significativamente asociada al ingreso tardío (OR 1,6[1,2;2,2]). Como conclusiones se ratifica el lugar que ocupan varios elementos en las características de la morbilidad por neumonía: edad avanzada, presencia de comorbilidades, y presentación no clásica del proceso. Fueron constatadas interrelaciones de importancia práctica entre la presencia de comorbilidades particulares, las formas clínicas de presentación, el momento del ingreso, y la utilización de antimicrobianos durante la atención prehospitalaria del paciente. Se destaca el papel del encamamiento en la extensión radiológica del proceso neumónico y en la presencia de derrame pleural de mediana o gran cuantía al momento del ingreso.

Community-acquired pneumonia is one of the respiratory conditions that causes the greatest demand for medical care, and is responsible for the largest number of deaths from infectious diseases in Cuba. The objective of the study was to determine the behavior of selected characteristics in patients hospitalized for pneumonia and to specify the existence of associations between some of these characteristics. An observational study, with a descriptive design, was carried out, which included 1,809 patients hospitalized for pneumonia between January 2012 and February 2020. Characteristics related to the basic, clinical-radiological conditions, and relative to management and evolution were analyzed, through analysis bivariate and multivariate (logistic regression). The series consisted mainly of elderly patients (79%), while 20% were bedridden. This condition was significantly associated with the state of advanced dementia (OR 7.6[5.5;10.4]) and was decisive in the "overlapping" presentation of the process (OR 1.5[1.09;2]). The "overlapping" presentation of pneumonia was significantly associated with late admission (OR 1.6[1.2;2.2]). As conclusions, the place occupied by several elements in the characteristics of pneumonia morbidity is ratified: advanced age, presence of comorbidities, and non-classical presentation of the process. Interrelationships of practical importance were found between the presence of comorbidities, the clinical forms of presentation, the time of admission, and the use of antimicrobials during the patient's prehospital care. The role of bed rest in the radiological extension of the pneumonic process and in the presence of medium or large pleural effusion at the time of admission is highlighted.

Tendencias en la mortalidad por neumonía en adultos en Chile, 2000-2016 / Trends in adult pneumonia mortality in Chile, 2000-2016

Objetivo: Analizar y modelar los cambios en la tendencia de la mortalidad por neumonía en la población mayor de 15 años de Chile, entre los años 2000 y 2016. Métodos: Estudio epidemiológico basado en información de bases de datos públicas de estadísticas vitales del Departamento de Estadística e Información en Salud (DEIS) y del Instituto Nacional de Estadística (INE) del Ministerio de Salud (MINSAL) de Chile. Los casos fueron identificados por los códigos CIE-10 J12-J18. Se calculó la tasa de mortalidad estandarizada por edad, según sexo y grupo etario. Se utilizó el análisis de regresión Joinpoint para modelar la mortalidad y estimar el porcentaje de cambio anual (CPA) en las tasas e identificar cambios significativos en las tendencias. Se utilizó el cambio del CPA como medida de resumen. Resultados: Durante el período de estudio, la tasa de mortalidad por neumonía en Chile disminuyó significativamente en un 61,9%, desde 56,3 muertes por 100.000 habitantes el año 2000 a 21,7 muertes por 100.000 habitantes en el año 2016, con un CPA de −4,2%, (p < 0,05). El 90% de los fallecidos tenían más de 65 años. Conclusiones: Las tasas de mortalidad por neumonía en Chile en mayores de 15 años muestran una tendencia a la disminución sostenida significativa en el período comprendido entre los años 2000 y 2016.

Objective: To analyze and model changes in the pneumonia mortality trend in the population over 15 years old of Chile, between 2000 and 2016. Methods: Epidemiological study based on information from public databases of vital statistics of the Department of Health Statistics and Information (DEIS) and the National Institute of Statistics (INE) of the Ministry of Health (MINSAL) of Chile. The cases were identified by the codes ICD-10 J12-J18. We calculated age-standardized overall mortality, according to sex and age group. Joinpoint regression analysis was used to model mortality and estimate the annual percentage of change (APC) in rates and identify significant changes in trends. APC was used as a summary measure. Results: During the period studied, the pneumonia mortality rate in Chile decreased significantly by 61.9%. Mortality rate diminished from 56.3 deaths per 100,000 inhabitants in 2000 to 21.7 deaths per 100,000 inhabitants in 2016 with an APC of −4.2%, (p < 0.05). Almost 90% of the deceased were over 65 years old. Conclusions: Mortality rates for pneumonia in Chile in people over 15 years of age show a significant sustained decreasing trend in the period between 2000 and 2016.

Como antecedentes patológicos de importancia se observó una asociación entre las variables con respecto a la neumonía nosocomial evidenciándose una relación significativa con diabetes mellitus (OR: 25.6; IC: 95% 13.4-48.7), enfermedad renal crónica (OR: 8.4; IC 95%: 4.49-16.0), enfermedad pulmonar obstructiva crónica (OR: 22.2; IC 95% 11.7-42.1), antecedente patológico de sinusitis (OR: 30.9; IC 95%: 7-46.2), utilización de sonda nasogástrica (OR: 13; IC 95%: 5-32) y, finalmente, al correlacionar la mortalidad con este tipo de infección pulmonar (OR: 26.1; IC 95%: 13 -49.1), evidenciando una relación entre las variables. Discusión. Los hallazgos muestran alta frecuencia de esta patología, lo que conlleva múltiples implicaciones en los pacientes como estancia prolongada y mortalidad, las cuales son condiciones que han sido identificadas por diferentes autores. Conclusiones. La neumonía nosocomial es un proceso infeccioso frecuente en la UCI, que tiene una alta morbimortalidad, relacionándose con los días de estancia y ventilación mecánica invasiva.

Introduction. Nosocomial pneumonia, or hospital-acquired pneumonia, is a significant cause of in-hospital infection that leads to high morbimortality. It occurs at a rate of 5 to 10 for every 1,000 hospital admissions and is considered the most common cause of in-hospital infection in Europe and the United States. Over 90% of episodes of pneumonia developed in intensive care units (ICUs) occur in ventilated patients. The objective of this study is to describe the prevalence and associated factors, such as hospitalization in the ICU, concomitant illnesses, and situations in patients older than 18 years of age with nosocomial pneumonia and hospital stay in an intensive care unit in a third-level clinic in the city of Cali, during the period between January 2015 and January 2016. Methodology. A cross-sectional, observational study with an analytical component. 353 medical records were reviewed, focusing on the factors associated with nosocomial pneumonia in the ICU, with hospital stay greater than or equal to 48 hours. The statistical analysis was performed with Epi Info version 7. Results. The average age of the studied cases was 55.17 years. The estimated prevalence for nosocomial pneumonia was 26%, with an average ICU hospital stay of 9.94 days and standard deviation of 8.30 days, and 4.27 days of invasive mechanical ventilation, with a standard deviation of 7.38 days, in which 26.35% (CI 95%: 22.0-31.1) acquired nosocomial pneumonia in the ICU. 43.06%: (CI 95%: 38.0-48.2) were women, of which 37.68% required invasive mechanical ventilation (CI 95%: 32.7-42.8). As an important pathological background, an association was observed between the variables with respect to nosocomial pneumonia, showing a significant relationship with diabetes mellitus (OR: 25.6; CI: 95% 13.4-48.7), chronic kidney disease (OR: 8.4; CI 95%: 4.49-16.0), chronic obstructive pulmonary disease (OR: 22.2; CI 95% 11.7-42.1), pathological backgrounds of sinusitis (OR: 30.9; CI 95%: 7-46.2), the use of nasogastric tube (OR: 13; CI 95%: 5-32) and, finally, correlating mortality with this type of pulmonary infection (OR: 26.1; CI 95%: 13-49.1), showing a relationship between the variables. Discussion. The findings show a high frequency of this pathology, which leads to multiple implications in patients, such as prolonged hospital stay and mortality, which are conditions that have been identified by different authors. Conclusions. Nosocomial pneumonia is a frequent infectious process in the ICU, which has a high morbimortality and is related to hospital stay and invasive mechanical ventilation.

Complicaciones agudas hospitalarias en adultos mayores con Enfermedad Cerebrovascular asociadas a características neuro-geriátricas / Acute hospital complications in older adults with Cerebrovascular Disease associated with neurogeriatric characteristics

INTRODUCCIÓN: La enfermedad cerebrovascular en los adultos mayores tiene implicaciones clínicas, sociales y económicas que pueden comprometer la funcionalidad y la calidad de vida. Es importante determinar las complicaciones que puede presentar el paciente geriátrico con enfermedad cerebrovascular durante los días de estancia hospitalaria. OBJETIVO: Determinar las características neuro-geriátricas asociadas a las complicaciones agudas no neurológicas y los días de hospitalización de los pacientes adultos mayores con enfermedad cerebrovascular. MATERIALES Y MÉTODOS: Estudio descriptivo prospectivo. Población de 120 y muestra de 73 pacientes mayores de 65 años con enfermedad cerebro vascular de la Unidad de Neurología del Hospital Carlos Andrade Marín que inició en agosto de 2020 y culminó en enero 2021. Se excluyó a pacientes que no cumplieron el criterio mencionado, con dependencia funcional total previa, patologías psiquiátricas previas, o personas que no aceptaron ser parte del estudio. Se efectuó el seguimiento de los pacientes desde el ingreso hasta el alta hospitalaria, para identificar complicaciones agudas no neurológicas y días de hospitalización. Se determinó las características neuro-geriátricas mediante las escalas de Barthel, Gijón, Charlson, Norton, Glasgow y NIHSS. Se obtuvo riesgo relativo e intervalos de confianza, considerando significativo un valor p<0,05. RESULTADOS: La edad media fue de 77 (±8,5) años. Las complicaciones fueron infección de tracto urinario (22,0%), neumonía (20,0%), desequilibrio hidroelectrolítico (19,0%), disfagia (13,0%) y úlceras por presión (9,0%). Las complicaciones que se presentaron significativamente ante una estancia hospitalaria prolongada comparada con quienes no las presentaron fueron la Neumonía (Media 5,81 (1,47 a 10,16) con IC 95%) y la infección del tracto urinario (Media 4,95 (1,52 a 8,38) con IC 95%). Según las características neuro-geriátricas y las complicaciones, encontramos diferencia estadísticamente significativa solo con en el grupo de riesgo bajo, según la escala de Norton RR 0,744 con IC 95% (0,584 - 0,949). CONCLUSIONES: Es importante realizar la valoración geriátrica integral al paciente neurológico tanto al ingreso como al egreso hospitalario, ya que permite detectar complicaciones que pueden pasar desapercibidas y prolongar la estancia hospitalaria.

INTRODUCTION: Cerebrovascular disease in older adults has clinical, social, and economic implications that can compromise functionality and quality of life. It is important to determine the complications that the geriatric patient with cerebrovascular disease may present during hospital days. OBJECTIVE: To determine the neuro-geriatric characteristics associated with acute non-neurological complications and hospital days in older adult patients with cerebrovascular disease. MATERIALS AND METHODS: Prospective descriptive study. Population of 120 and sample of 73 patients older than 65 years with cerebrovascular disease from the Neurology Unit of the Carlos Andrade Marín Hospital that began in August 2020 and culminated in January 2021. Patients who did not meet the aforementioned criteria, with previous total functional dependence, previous psychiatric pathologies, or people who did not agree to be part of the study were excluded. Patients were followed up from admission to hospital discharge to identify acute non-neurological complications and days of hospitalization. Neuro-geriatric characteristics were determined using the Barthel, Gijon, Charlson, Norton, Glasgow and NIHSS scales. Relative risk and confidence intervals were obtained, considering a p-value <0.05 as significant. RESULTS: Mean age was 77 (±8.5) years. Complications were urinary tract infection (22.0%), pneumonia (20.0%), water and electrolyte imbalance (19.0%), dysphagia (13.0%) and pressure ulcers (9.0%). Complications that occurred significantly in the face of a prolonged hospital stay compared to those who did not present were Pneumonia (Mean 5.81 (1.47 to 10.16) with 95% CI) and urinary tract infection (Mean 4.95 (1.52 to 8.38) with 95% CI). According to neuro-geriatric characteristics and complications, we found statistically significant difference only with in the low risk group, according to the Norton scale RR 0.744 with 95% CI (0.584 - 0.949). CONCLUSIONS: It is important to perform comprehensive geriatric assessment of the neurological patient both on admission and hospital discharge, as it allows the detection of complications that may go unnoticed and prolong hospital stay.

Déficit de base, lactato e índice de shock como predictores de mortalidad en lesionados múltiples / Base Deficit, Lactate and Shock Index as Mortality Predictors in Trauma Patients

Introducción: Las respuestas fisiológicas a la hemorragia, como hipotensión y taquicardia, no siempre son proporcionales al estado de choque, lo cual ha llevado a la necesidad de usar otros predictores. Objetivo: Analizar el comportamiento del déficit de base, lactato e índice de shock severo como predictores de mortalidad en pacientes lesionados múltiples. Métodos: Se realizó un estudio analítico, observacional y retrospectivo en el Servicio de Anestesiología y Reanimación del Hospital Universitario "General Calixto García", entre agosto de 2018 y agosto de 2020. La muestra fue de 50 pacientes, según criterio de selección no probabilístico del investigador. Resultados: Los pacientes que sufrieron trauma craneal tuvieron siete veces más riesgo de morir. El índice de shock severo, a las tres horas triplicó el riesgo de morir. El lactato y el déficit de base se correlacionaron con un índice de shock mayor de uno, de forma significativa. La transfusión sanguínea duplicó el riesgo de morir, mientras que los requerimientos de aminas, no mostraron ser factores de mal pronóstico. Dentro de las complicaciones la respuesta inflamatoria sistémica mostró tener nueve veces mayor riesgo de morir y la disfunción múltiple de órgano siete veces, pero la presencia de neumonía no influyó en la muerte. Conclusiones: El índice de shock severo se consideró un factor pronóstico de mortalidad en pacientes politraumatizados al triplicar el riesgo de morir y guardó relación con el lactato elevado y la alteración de los valores del déficit de bases(AU)

Introduction: Physiological responses to hemorrhage, such as hypotension and tachycardia, are not always proportional to the state of shock, which has led to the need to use other predictors. Objective: To analyze the characteristics of base deficit, lactate and severe shock index as predictors of mortality in multiply injured patients. Methods: An analytical, observational and retrospective study was carried out in the anesthesiology and resuscitation service of General Calixto García University Hospital, between August 2018 and August 2020. The sample was made up of 50 patients, according to nonprobabilistic selection criteria of the researcher. Results: Patients who suffered cranial trauma were seven times more likely to die. The index of severe shock at three hours tripled the risk of death. Lactate and baseline deficit correlated significantly with shock index greater than one. Blood transfusion doubled the risk of death, while amine requirements were not shown to be poor prognostic factors. Among complications, systemic inflammatory response was shown to have nine times higher risk of dying and multiple organ dysfunction seven times, but the presence of pneumonia did not influence death. Conclusions: The severe shock index was considered a prognostic factor for mortality in polytraumatized patients, as far as it tripled the risk of dying and was related to elevated lactate and altered base deficit values(AU)

Cigarros eletrônicos e suas consequências histopatológicas relacionadas à doenças pulmonares / E-cigarettes and histopathological consequences related to lung diseases

O cigarro eletrônico surgiu como uma tentativa para minimizar a dependência ao uso de tabaco, entretanto, engloba controvérsias e dúvidas acerca das reais implicações para o organismo humano. Diante disso, o presente estudo tem como objetivo realizar uma revisão da literatura a fim de relacionar o uso de cigarro eletrônico com suas consequências para os humanos. Os estudos analisados relatam experimentos in vitro e in vivo em camundongos, demonstrando menor concentração de poluentes e nocividades no cigarro eletrônico comparado ao convencional, porém, seu potencial efeito maléfico está relacionado à composição do e-líquido, à maneira do uso e à variedade de aromas presentes nos produtos. Além disso, foram verificadas lesões celulares, hiperreatividade das vias aéreas, liberação de citocinas ­ IL-8, IL-10 e TNF, redução da ação antimicrobiana de queratinócitos e potencial apoptose nas células alveolares. Foi observado também um aumento em até cinco vezes da concentração de carboxihemoglobina em comparação ao cigarro comum e um aumento na auto renovação de células de adenocarcinoma pulmonar de células não pequenas, devido à expressão de SOX2. Observa-se também que em casos de DPOC, o cigarro eletrônico não apresenta agravamentos na fisiologia respiratória, contrapondo outras ocorrências como asma, pneumonia, câncer de pulmão e doenças infecciosas que podem ser ocasionadas ou exacerbadas pelo seu uso. Contudo, pelo curto prazo de observação de seus efeitos, não é possível determinar com precisão a segurança dos cigarros eletrônicos, dessa forma, faz-se necessário que mais pesquisas longitudinais sejam desenvolvidas, auxiliando, assim, na construção de evidências sobre a segurança dos cigarros eletrônicos e na regulamentação futura do produto.

Electronic cigarettes emerged as an attempt to minimize tobacco dependence. However, its use is surrounded by controversies and doubts about the real implications for the human organism. Therefore, this study aims at performing a review of the most recent literature to corelate the use of e-cigarettes with their consequences for the human body. The analyzed studies relate in vitro and in vivo experiments on mice, demonstrating lower concentration of pollutants and harmfulness in the electronic cigarette than in conventional cigarettes. However, its potential harmful effect is related to the composition of the e-liquid, in its use and in the variety of aromas in the products. In addition, cellular lesions, airway hyperreactivity, release of IL-8, IL-10 and TNF cytokines could be observed, as well as reduced keratinocyte antimicrobial action and potential apoptosis in alveolar cells. An increase of up to five-fold the concentration of carboxyhemoglobin in comparison to ordinary cigarettes and an increase in self-renewal of non-small pulmonary adenocarcinoma cells due to the expression of SOX2 have also been related. It could also be observed that in COPD cases, e-cigarettes do not present worsening in respiratory physiology, which contrasts with other occurrences such as asthma, pneumonia, lung cancer, and infectious diseases that can be caused or exacerbated by its use. However, due to the short term of observation of the effects, the safety of e-cigarettes could not be accurately determined, thus, the need for further longitudinal research is necessary, which could be used to help build evidence about the safety of e-cigarettes and also to create future regulation of the product.

Aspergilosis pulmonar invasiva en paciente pediátrico / Invasive pulmonary aspergillosis in a pediatric patient

La creciente emergencia de las enfermedades infecciosas y el aumento del número de individuos que tienen afectada su competencia inmunológica se ha convertido en un reto. Por otro lado, considerando el género Aspergillus, como un agente etiológico de infección, causa importante de morbilidad y mortalidad en pacientes inmunocomprometidos. Presentamos el caso de preescolar femenino de 3 años y 8meses con antecedente de teratoma maduro fetiforme, quien posterior a 6 meses de su exéresis, se realiza tomografía axial computarizada (TAC) de Tórax control evidenciándose bronquiectasias centrales con opacidades tubulares y saculares de distribución bronquial, con localización principalmente en lóbulo superior de hemitórax izquierdo, disminución del volumen pulmonar ipsilateral con incipiente desplazamiento del cardiomediastino a la izquierda y escaso derrame pleural izquierdo, examen físico sin alteraciones, por lo que ingresa con diagnóstico de enfermedad granulomatosa en estudio. Se realiza detección de antígeno galactomanano que reporta positivo en dos determinaciones por lo que se replantea el diagnóstico a Aspergilosis Pulmonar Invasiva, cumple tratamiento con voriconazol por 21 días, con mejoría significativa de las lesiones pulmonares en TAC de tórax, egresando con tratamiento con itraconazol a cumplir por 6 semanas. El inicio precoz del tratamiento constituye un factor pronóstico fundamental de la aspergilosis invasiva, siendo el voriconazol la primera línea(AU)

The growing emergence of infectious diseases and increasing the number of individuals that have affected their immune competence has be come a challenge. Furthermore, considering the genus Aspergillus, as an etiologic agent of infection, which causes significant morbidity and mortality in immunocompromised patients. We present a case of a female preschool 3 years and 8 months with a history of matureteratoma fetiforme, who after 6 months of excision, compute dtomography (CT) scan control is performed where central bronchiectasis are evident with tubular opacities and saculares bronchial distribution, located mainly in the upper lobe of left chest, decreased left lung volume with incipient displacement of the heart and medistino left and low left pleural effusion, physical examination no alterations to income, so you enter with diagnosis of granulomatous disease study. antigen detection galactomannan reporting positive in two determinations so the diagnosis of invasive pulmonary aspergillosis rethinks meets voriconazole for 21 days, with significant improvement of lunglesions in chest CT scan, graduating with itraconazole therapy is performed to meet for 6 weeks. The early initiation of treatmentis a fundamental prognostic factor of invasive aspergillosis, constituting the first line in voriconazole(AU)

Características clínicas de adultos mayores con neumonía adquirida en la comunidad / Clinical characteristics of older adults with community-acquired pneumonia

La neumonía adquirida en la comunidad es una enfermedad infecciosa común que causa una morbilidad y mortalidad sustanciales. Las personas mayores son las más frecuentemente afectadas, y se deben considerar varios aspectos relacionados con el cuidado de esta condición en los ancianos. El patógeno más común en esta patología sigue siendo Streptococcus pneumoniae, seguido de Haemophilus influenzae, Mycoplasma pneumoniae. El objetivo de este estudio fue determinar las características clínicas de adultos mayores con esta patología en el hospital "Alfredo Noboa Montenegro". Para las variables cualitativas fue empleada la frecuencia absoluta y el por ciento. Para la asociación entre variables cualitativas se utilizó la prueba Jicuadrado de independencia. En caso de las tablas de contingencia 2x2 cuando tuvo alguna celda con frecuencia esperada menor que 5 se utilizó el test exacto de Fisher. Más del 54% de los pacientes estudiados fue clasificado como grado II; de ellos el mayor porcentaje (66,7%) correspondió a los hombres. Le siguió en orden de frecuencia el grado III con 25% y alrededor del 83% fue del sexo femenino. No se obtuvo asociación estadística entre el sexo y el grado de los pacientes estudiados por lo que se pude afirmar que ambas variables fueron independientes. En la mayoría de casos los pacientes resultan infra diagnosticados desde los niveles primarios de atención al confundirlos con otro tipo de patologías, lo que provoca un retraso en la identificación y tratamiento del paciente que en el futuro influye en un pronóstico negativo de este(AU)

Community-acquired pneumonia is a common infectious disease that causes substantial morbidity and mortality. Elderly people are frequently affected, and several issues related to care of this condition in the elderly have to be considered. The most common pathogen in this pathology is still Streptococcus pneumoniae, followed by other pathogens such as Haemophilus influenzae, Mycoplasma pneumonia. The objective of this study was to determine the clinical characteristics of older adults with this disease in hospital "Alfredo Noboa Montenegro". For the qualitative variables the absolute frequency and the percent were used. For the association between qualitative variables, the Chi-square independence test was used. In the case of the 2x2 contingency tables, when Fisher had an expected cell shorter than 5, Fisher's exact test was used. More than 54% of the patients studied were classified as grade II; of them, the highest percentage (66.7%) corresponded to men. Next in order of frequency was grade III with 25% and about 83% was female. There was no statistical association between sex and the degree of the patients studied, so we could say that both variables were independent. In the majority of cases, patients are diagnosed from the primary care levels when they are confused with other types of pathologies, which causes a delay in the identification and treatment of the patient that in the future influences a negative prognosis(AU)

Factores asociados a defunción en pacientes hospitalizados por COVID-19 / Factors associated to death in patients hospitalized due to COVID-19

Introducción: el SARS-CoV-2 fue notificado por la Organización Mundial de la Salud en enero de 2020 como emergencia mundial debido a su intenso contagio y cuadro clínico, que se agrava en personas susceptibles. Objetivo: describir factores asociados a defunción en pacientes con COVID-19 y neumonía hospitalizados en tercer nivel.Material y métodos: estudio de casos y controles no pareado. Se obtuvo información general mediante entrevista; del expediente se tomaron datos de hospitalización, imágenes radiológicas, parámetros de laboratorio y tratamientos. Se empleó estadística descriptiva, t de student, U de Mann-Whitney y chi cuadrada para identificar variables asociadas a defunción, y modelos de regresión logística binaria ajustada para proponer variables de antecedentes del paciente, parámetros clínicos y tratamientos que explicaran la defunción.Resultados: atendimos 5339 pacientes sospechosos de COVID-19: 3117 positivos (59%), 1029 hospitalizados por neumonía y 513 defunciones (16.46%). Para el análisis, se tomaron 1110, se seleccionaron 399 casos de defunción y 357 controles egresados por mejoría. La edad promedio fue 57.8 años; 59% fueron hombres. La estancia hospitalaria en casos fue 9.8 (DE 10.9) y en controles 12.5 (DE 10.2).Conclusiones: las variables asociadas a mortalidad fueron: mayores de 40 años, radiografía de tórax > 50% de afectación, intubación, deshidrogenasa láctica > 500, proteína C reactiva > 10 e insuficiencia orgánica; las asociadas a mejoría: estancia en unidad de cuidados intensivos, uso de antibióticos parenterales de amplio espectro, esteroides y anticoagulante enoxiheparina. El sexo, la diabetes y las comorbilidades no mostraron asociación.

Background: SARS-CoV-2 virus was notified by the World Health Organization in January 2020 as a global emergency, due to its intense transmission, and the clinical picture, that is aggravated in susceptible people.Objective: To describe the factors associated with death in COVID-19 and pneumonia patients hospitalized in a third-level center. Material and methods: An undivided case-control study was conducted. It was conducted an interview to obtain general information; from the medical record were collected hospitalization data, radiological images, laboratory parameters, and treatments used. It was used descriptive statistics. Student's t, Mann-Whitney U, and chi-squared were used to identify variables associated with death, and models of adjusted binary logistic regression to propose which variables of the patient's history, clinical parameters and treatments explained the death. Results: We treated 5339 patients with suspicion of COVID-19: 3117 positive (59%), 1029 hospitalized due to pneumonia, and 513 deaths (16.46%). For the analysis, 1110 patients were taken, 399 death cases were selected and 357 controls discharged due to improvement. The average age was 57.8 years; 59% were male. The hospital stay in cases was 9.8 (SD 10.9), and in controls 12.5 (SD 10.2). Conclusions: The variables associated with mortality were: patients older than 40 years, chest radiography image > 50% involvement, intubation, lactic dehydrogenase > 500, C-reactive protein > 10, and organ failure; variables associated with improvement were: stay in the intensive care unit, use of broad spectrum parenteral antibiotics, steroids, and use of the anticoagulant enoxyheparin. Sex, diabetes, and comorbidities did not show significant association.

Statistical modeling of hospital admissions for pneumonia in Campo Grande / Modelagem estatística das internações hospitalares por pneumonia em Campo Grande / Modelado estadístico de ingresos hospitalarios por neumonía en Campo Grande

Justification and Objectives: Brazil lacks consistent epidemiological data on the respiratory morbidity of children and older adults, which makes it difficult to plan and execute effective preventive and health promotion actions. The objective of this study was to analyze the adjustments of distributions (Weibull, Normal, Gamma, Logistic) of historical series of hospitalizations for respiratory diseases (total hospitalizations), from 2011 to 2015, in Campo Grande, Mato Grosso do Sul. Methods: to determine the statistical models, four statistical indicators (coefficient of determination, mean root square error, mean absolute error and mean absolute percentage error) were performed from 2011 to 2015. Parameter estimates are obtained for the models adopted in the study, with and without a regression structure. Results: the results showed that Weibull, Gamma, Normal and Logistic distributions, applied to the series of hospitalizations for respiratory diseases in Campo Grande, were satisfactory in determining the shape and scale parameters, and the statistical indicators R2 , MAE, RSME and MAPE confirmed the data goodness-of-fit, and the graphical analysis indicated a satisfactory distribution fit. Conclusion: the analysis of monthly values indicates that Gamma is the best of the four distributions based on those selected. The regression model can be adjusted to the data and used as an alternative distribution that describes the hospitalization data considered in Campo Grande, Brazil.(AU)

Protocolo clínico de diagnóstico y tratamiento de pacientes con neumonía adquirida en la comunidad que ingresan a la Unidad de Cuidados Intensivos / Clinical protocol for diagnosis and treatment of patients with community-acquired pneumonia admitted to the Intensive Care Unit

La neumonía es una infección frecuente que se presenta en todas las edades, en cualquier tipo de pacientes y a nivel co-munitario u hospitalario. La neumonía que se origina en la comunidad afecta a los pacientes con comorbilidades y en los extremos de la vida. La mortalidad de la neumonía comunitaria (NC) per-manece elevada, los sistemas de salud deben implementar estrategias para diagnosticar y tratar de forma rápida a estos pacientes. Cuando un paciente con neumonía comunitaria es ingresado en la emergencia de cualquier hospital se debe categorizar su estado para que reciba el mejor tratamiento posible. La Unidad de Cuidados Intensivos (UCI) participa en la detección de los pacientes con neu-monía adquirida en la comunidad grave, con el objetivo de priorizar su atención para lograr las metas de manejo lo más rápido posible y disminuir la mortalidad de estos pacientes.

Pneumonia is a common infection that occurs in all ages, in any type of patient and at the community or hospital level. Community-originating pneumonia affects patients with comorbidities and at the ex-tremes of life. Mortality from commu-nity pneumonia remains high, health sys-tems must implement strategies to quickly diagnose and treat these patients. When a patient with community pneumonia is admitted to any hospital emergency, their condition must be categorized so that they receive the best possible treat-ment. The Intensive Care Unit (ICU) participates in the detection of patients with severe community-acquired pneu-monia, with the objective of prioritizing their care to achieve management goals as quickly as possible and reduce the mortality of these patients.

Performance of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage Scoring System (STSS) and Confusion, Uremia, Respiratory rate, Blood pressure and age ≥ 65 (CURB-65) score among patients with COVID-19 pneumonia in an emergency department triage setting: a retrospective study

ABSTRACT BACKGROUND: Healthcare institutions are confronted with large numbers of patient admissions during large-scale or long-term public health emergencies like pandemics. Appropriate and effective triage is needed for effective resource use. OBJECTIVES: To evaluate the effectiveness of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage Scoring System (STSS) and Confusion, Uremia, Respiratory rate, Blood pressure and age ≥ 65 years (CURB-65) score in an emergency department (ED) triage setting. DESIGN AND SETTING: Retrospective study in the ED of a tertiary-care university hospital in Düzce, Turkey. METHODS: PMEWS, STSS and CURB-65 scores of patients diagnosed with COVID-19 pneumonia were calculated. Thirty-day mortality, intensive care unit (ICU) admission, mechanical ventilation (MV) need and outcomes were recorded. The predictive accuracy of the scores was assessed using receiver operating characteristic curve analysis. RESULTS: One hundred patients with COVID-19 pneumonia were included. The 30-day mortality was 6%. PMEWS, STSS and CURB-65 showed high performance for predicting 30-day mortality (area under the curve: 0.968, 0.962 and 0.942, respectively). Age > 65 years, respiratory rate > 20/minute, oxygen saturation (SpO2) < 90% and ED length of stay > 4 hours showed associations with 30-day mortality (P < 0.05). CONCLUSIONS: CURB-65, STSS and PMEWS scores are useful for predicting mortality, ICU admission and MV need among patients diagnosed with COVID-19 pneumonia. Advanced age, increased respiratory rate, low SpO2 and prolonged ED length of stay may increase mortality. Further studies are needed for developing the triage scoring systems, to ensure effective long-term use of healthcare service capacity during pandemics.

Neumonía adquirida en la comunidad en pacientes que requirieron hospitalización / Community acquired pneumonia in patients requiring hospitalization

Resumen La neumonía adquirida en la comunidad (NAC) representa un importante problema sanitario y ~20% de los pacientes requiere hospitalización. El objetivo principal del trabajo fue determinar las características clínico-imagenológicas de los episodios de NAC que requirieron internación. Los objetivos secundarios fueron determinar el rédito diagnóstico de los estudios microbiológicos e identificar las complicaciones. Realizamos un estudio analítico retrospectivo en un hospital de tercer nivel durante el período 2017-2019, en adultos admitidos por NAC, excluyendo embarazadas. Identificamos 340 episodios en 321 pacientes, la mediana de edad fue 75 años (rango intercuartil 57-85). Los factores de riesgo más frecuentes fueron inmunocompromiso (30%), enfermedad neurológica (22%) y enfermedad renal crónica (17%). Según tres scores pronósticos de gravedad, CURB65, qSOFA y PSI/PORT, 216 (63.5%), 290 (85.3%) y 130 (38%) episodios fueron identificados como de bajo riesgo, respectivamente. Del total de los episodios, 49 (14.4%) requirieron internación en unidad de cuidados intensivos, 39 (11.5%) ventilación mecánica y se registraron 30 (8.8%) muertes durante la hospitalización. Los patrones de imagen más frecuentes fueron consolidativo en 134 (39.4%), intersticio-alveolar en 98 (28.8%) y mixto entre ambos patrones en 67 (19.7%) episodios. Identificamos el agente causal en 79 (23.2%) episodios. Los microorganismos aislados más frecuentemente fueron influenza en 37 (10.9%) y Streptococcus pneumoniae en 11 (3.2%). La mayoría de los episodios afectaron pacientes ancianos y el principal patrón radiológico fue el consolidativo. El agente causal se pudo identificar en uno de cada cuatro episodios y el método con mayor rédito diagnóstico fue el test para influenza.

Abstract Community-acquired pneumonia (CAP) represents a major health issue and ~20% of the patients require in-hospital attention. The main objective of the study was to determine clinical-imaging features of CAP episodes requiring hospitalization. The secondary objectives were to determine the diagnostic yield of microbiological analyses and the medical complications. A retrospective analytical study was conducted on adults admitted due to CAP in a third-level hospital in the period 2017-2019. Pregnant women were excluded. A total of 340 CAP episodes were identified in 321 patients; the median age was 75 years old (interquartile range 57-85). The most frequent risk factors were immunocompromise 102 (30%), neurological disease 75 (22%), and chronic kidney disease 58 (17%). According to three prognostic scores, CURB65, qSOFA and PSI/PORT, 216 (63.5%), 290 (83.5%) and 130 (38%) patients were identified as low risk, respectively. A total of 49 (14.4%) episodes required admission at the critical care unit and 39 (11.5%) required mechanical ventilation; 30 patients (8.8%) died during hospitalization. The radiologic patterns most frequently found were consolidation in 134 (39.4%), interstitial-alveolar pattern in 98 (28.8%), and the combination of both patterns in 67 (19.7%) episodes. Identification of the causal agent was achieved in 79 (23.2%) episodes. The most frequently isolated microorganisms were influenza virus in 37 (10.9%) episodes and Streptococcus pneumoniae in 11 (3.2%). Most of the hospitalized CAP patients were elderly with consolidative radiological patterns. The causal agent could be identified in less than a quarter of the patients, with the influenza test being the method with the highest diagnostic yield.
