Histerectomía con embrión en útero en paciente con tromboembolismo pulmonar: reporte de un caso / Hysterectomy with embryo in utero in a patient with pulmonary thromboembolism: report of a case

Resumen Antecedentes: la histerectomía en bloque es un procedimiento controvertido y con poca literatura actualizada. Se define como la extirpación del útero grávido con su contenido gestacional in situ, las indicaciones para la realización de esta cirugía son los procesos neoplásicos (como la causa más frecuente( procesos sépticos, enfermedad trofoblástica y hemorragia secundaria a inserción placentaria anómala. Caso clínico: paciente de 45 años con embarazo de 8 semanas y 5 días, según la fecha de última regla, con miomatosis uterina gigante asociada con tromboembolismo pulmonar, quien decide la interrupción voluntaria del embarazo y realizarse la histerectomía en bloque. Conclusiones: la histerectomía en bloque es una cirugía poco realizada en la actualidad, sin embargo, este abordaje quirúrgico es una opción segura y efectiva para la interrupción voluntaria del embarazo, y no se debe descartar entre las alternativas de tratamiento quirúrgico, siempre individualizando cada paciente.

ABSTRACT BACKGROUND: En bloc hysterectomy is defined as the removal of the pregnant uterus with its gestational content in situ. The indications for performing this en bloc surgery are neoplastic processes, as the most frequent cause; septic processes, trophoblastic disease and hemorrhage secondary to abnormal placental insertion, however, it is a controversial procedure, and with little updated literature. CLINICAL CASE: 45-year-old patient with a pregnancy of 8 weeks and 5 days, with giant uterine myomatosis associated with pulmonary thromboembolism who decided to voluntarily terminate the pregnancy, and it was decided to perform en bloc hysterectomy. CONCLUSIONS: En bloc hysterectomy is a surgery rarely performed at present, however, this surgical approach is a safe and effective option for the voluntary termination of pregnancy, and it should not be ruled out among the surgical treatment alternatives, always individualizing each patient.

Serum glucose-potassium ratio predicts inhospital mortality in patients admitted to coronary care unit

SUMMARY OBJECTIVE: The aim of our study was to determine the role of serum glucose-potassium ratio in predicting inhospital mortality in coronary care unit patients. METHODS: This study used data from the MORtality in CORonary Care Units in Turkey study, a national, observational, multicenter study that included all patients admitted to coronary care units between September 1, 2022, and September 30, 2022. Statistical analyses assessed the independent predictors of mortality. Two models were created. Model 1 included age, history of heart failure, chronic kidney disease, hypertension, diabetes mellitus, and coronary artery disease. Model 2 included glucose-potassium ratio in addition to these variables. Multivariate regression and receiver operating characteristic analysis were performed to compare Model 1 and Model 2 to identify if the glucose-potassium ratio is an independent predictor of inhospital mortality. RESULTS: In a study of 3,157 patients, the mortality rate was 4.3% (n=137). Age (p=0.002), female gender (p=0.004), mean blood pressure (p<0.001), serum creatinine (p<0.001), C-reactive protein (p=0.002), white blood cell (p=0.002), and glucose-potassium ratio (p<0.001) were identified as independent predictors of mortality through multivariate regression analysis. The receiver operating characteristic analysis indicated that Model 2 had a statistically higher area under the curve than Model 1 (area under the curve 0.842 vs area under the curve 0.835; p<0.001). A statistically significant correlation was found between the inhospital mortality and glucose-potassium ratio (OR 1.015, 95%CI 1.006-1.024, p<0.001). CONCLUSION: Our study showed that the glucose-potassium ratio may be a significant predictor of inhospital mortality in coronary care unit patients.

Hipotermia terapéutica: estudio descriptivo de una cohorte de 10 años en un hospital público de alta complejidad / Therapeutic hypothermia: A descriptive, cohort study conducted over 10 years at a tertiary care public hospital

Introducción. La hipotermia terapéutica (HT) reduce el riesgo de muerte o discapacidad en niños con encefalopatía hipóxico-isquémica (EHI) moderada-grave. Objetivo. Describir una población de pacientes con EHI que requirió HT y su evolución hasta el alta hospitalaria. Población y métodos. Estudio descriptivo de cohorte retrospectivo. Se analizaron todos los pacientes que ingresaron a HT entre 2013 y 2022. Se evaluaron datos epidemiológicos, clínicos, de monitoreo, tratamiento, estudios complementarios y condición al alta. Se compararon los factores de riesgo entre pacientes fallecidos y sobrevivientes, y de estos, los que requirieron necesidades especiales al alta (NEAS). Resultados. Se incluyeron 247 pacientes. Mortalidad: 11 %. Evento centinela más frecuente: período expulsivo prolongado (39 %). Inicio del tratamiento: mediana 5 horas de vida. Convulsiones: 57 %. Eritropoyetina intravenosa: 66,7 %. Patrón anormal de monitoreo de función cerebral: 52 %. Normalización del monitoreo: mediana 24 horas. Resonancia magnética patológica: 42 %. Variables predictoras de mortalidad: Sarnat y Sarnat grave, y ecografía patológica al ingreso. Conclusión. La mortalidad global fue del 11 %. Las derivaciones aumentaron en forma más evidente a partir del año 2018. El horario de inicio de HT fue más tardío que en reportes anteriores. Los signos neurológicos de gravedad según la escala de Sarnat y Sarnat y la ecografía cerebral basal patológica fueron predictores independientes de mortalidad al alta. Los pacientes con NEAS presentaron normalización del trazado del electroencefalograma de amplitud integrada más tardío. El hallazgo más frecuente en la resonancia fue la afectación de los ganglios basales. No se encontraron diferencias clínicas ni de complicaciones estadísticamente significativas entre los pacientes que recibieron eritropoyetina.

Introduction. Therapeutic hypothermia (TH) reduces the risk of death or disability in children with moderate to severe hypoxic ischemic encephalopathy (HIE). Objective. To describe a population of patients with HIE that required TH and their course until discharge. Population and methods. Retrospective, descriptive, cohort study. All patients admitted to TH between 2013 and 2022 were studied. Epidemiological, clinical, monitoring, and treatment data were assessed, together with supplementary tests and condition at discharge. Risk factors were compared between deceased patients and survivors; and, among the latter, those requiring special healthcare needs (SHCN) at discharge. Results. A total of 247 patients were included. Mortality: 11%. Most common sentinel event: prolonged second stage of labor (39%). Treatment initiation: median of 5 hours of life. Seizures: 57%. Intravenous erythropoietin: 66.7%. Abnormal pattern in brain function monitoring: 52%. Normalization of monitoring: median of 24 hours. Pathological magnetic resonance imaging: 42%. Predictor variables of mortality: severe Sarnat and Sarnat staging and pathological ultrasound upon admission. Conclusion. The overall mortality rate was 11%. Referrals increased more markedly since 2018. The time of TH initiation was later than in previous reports. Severe neurological signs as per the Sarnat and Sarnat staging and a pathological baseline cranial ultrasound were independent predictors of mortality at discharge. Patients with SHCN at discharge showed a normalized tracing in the amplitude-integrated electroencephalography performed later. The most common finding in the magnetic resonance imaging was basal ganglia involvement. No statistically significant differences were observed in terms of clinical characteristics or complications among patients who received erythropoietin.

Acute kidney injury in nonagenarians: clinical characteristics and mortality / Injúria renal aguda em nonagenários: características clínicas e mortalidade

Abstract Introduction: Nonagenarians constitute a rising percentage of inpatients, with acute kidney injury (AKI) being frequent in this population. Thus, it is important to analyze the clinical characteristics of this demographic and their impact on mortality. Methods: Retrospective study of nonagenarian patients with AKI at a tertiary hospital between 2013 and 2022. Only the latest hospital admission was considered, and patients with incomplete data were excluded. A logistic regression analysis was conducted to define risk factors for mortality. A p-value < 0.05 was considered statistically significant. Results: A total of 150 patients were included, with a median age of 93.0 years (91.2-95.0), and males accounting for 42.7% of the sample. Sepsis was the most common cause of AKI (53.3%), followed by dehydration/hypovolemia (17.7%), and heart failure (17.7%). ICU admission occurred in 39.3% of patients, mechanical ventilation in 14.7%, vasopressors use in 22.7% and renal replacement therapy (RRT) in 6.7%. Death occurred in 56.7% of patients. Dehydration/hypovolemia as an etiology of AKI was associated with a lower risk of mortality (OR 0.18; 95% CI 0.04-0.77, p = 0.020). KDIGO stage 3 (OR 3.15; 95% CI 1.17-8.47, p = 0.023), ICU admission (OR 12.27; 95% CI 3.03-49.74, p < 0.001), and oliguria (OR 5.77; 95% CI 1.98-16.85, p = 0.001) were associated with mortality. Conclusion: AKI nonagenarians had a high mortality rate, with AKI KDIGO stage 3, oliguria, and ICU admission being associated with death.

Resumo Introdução: Nonagenários constituem um percentual de pacientes internados em ascensão, sendo a injúria renal aguda (IRA) frequente nesses pacientes. Sendo assim, é importante analisar as características clínicas dessa população e seu impacto na mortalidade. Métodos: Estudo retrospectivo de pacientes nonagenários com IRA entre 2013 e 2022 em um hospital terciário. Apenas o último internamento foi considerado e pacientes com dados incompletos foram excluídos. Uma análise por regressão logística foi realizada para definir fatores de risco para mortalidade. Um valor de p < 0,05 foi considerado significativo. Resultados: Foram incluídos 150 pacientes com mediana de idade 93,0 anos (91,2-95,0) e sexo masculino em 42,7%. Sepse foi a causa mais comum de IRA (53,3%), seguida de desidratação/hipovolemia (17,7%) e insuficiência cardíaca (17,7%). Admissão na UTI ocorreu em 39,3% dos pacientes, ventilação mecânica em 14,7%, uso de vasopressores em 22,7% e realização de terapia renal substitutiva (TRS) em 6,7%. Óbito ocorreu em 56,7% dos pacientes. Desidratação/hipovolemia como etiologia da IRA foi associado a menor risco de mortalidade (OR 0,18; IC 95% 0,04-0,77, p = 0,020). Estágio KDIGO 3 (OR 3,15; IC 95% 1,17-8,47, p = 0,023), admissão na UTI (OR 12,27; IC 95% 3,03-49,74, p < 0,001) e oligúria (OR 5,77; IC 95% 1,98-16,85, p = 0,001) foram associados à mortalidade. Conclusão: Nonagenários com IRA apresentaram alta mortalidade e IRA KDIGO 3, oligúria e admissão na UTI foram associadas ao óbito.

Predictors of autosomal dominant polycystic kidney disease progression: a Brazilian single-center cohort / Preditores de progressão da doença renal policística autossômica dominante: uma coorte brasileira de centro único

Abstract Introduction: Identifying risk factors for autosomal dominant polycystic kidney disease (ADPKD) progression is important. However, studies that have evaluated this subject using a Brazilian sample is sparce. Therefore, the aim of this study was to identify risk factors for renal outcomes and death in a Brazilian cohort of ADPKD patients. Methods: Patients had the first medical appointment between January 2002 and December 2014, and were followed up until December 2019. Associations between clinical and laboratory variables with the primary outcome (sustained decrease of at least 57% in the eGFR from baseline, need for dialysis or renal transplantation) and the secondary outcome (death from any cause) were analyzed using a multiple Cox regression model. Among 80 ADPKD patients, those under 18 years, with glomerular filtration rate <30 mL/min/1.73 m2, and/or those with missing data were excluded. There were 70 patients followed. Results: The factors independently associated with the renal outcomes were total kidney length - adjusted Hazard Ratio (HR) with a 95% confidence interval (95% CI): 1.137 (1.057-1.224), glomerular filtration rate - HR (95% CI): 0.970 (0.949-0.992), and serum uric acid level - HR (95% CI): 1.643 (1.118-2.415). Diabetes mellitus - HR (95% CI): 8.115 (1.985-33.180) and glomerular filtration rate - HR (95% CI): 0.957 (0.919-0.997) were associated with the secondary outcome. Conclusions: These findings corroborate the hypothesis that total kidney length, glomerular filtration rate and serum uric acid level may be important prognostic predictors of ADPKD in a Brazilian cohort, which could help to select patients who require closer follow up.

Resumo Introdução: É importante identificar fatores de risco para progressão da doença renal policística autossômica dominante (DRPAD). Entretanto, são escassos os estudos que avaliam esse assunto utilizando amostra brasileira. Portanto, o objetivo deste estudo foi identificar fatores de risco para desfechos renais e óbito em coorte brasileira de pacientes com DRPAD. Métodos: Os pacientes tiveram o primeiro atendimento médico entre janeiro/2002 e dezembro/2014, sendo acompanhados até dezembro/2019. Associações entre variáveis clínicas e laboratoriais com desfecho primário (redução sustentada de pelo menos 57% na TFGe em relação ao valor basal, necessidade de diálise ou transplante renal) e desfecho secundário (óbito por qualquer causa) foram analisadas pelo modelo de regressão múltipla de Cox. Entre 80 pacientes com DRPAD, foram excluídos aqueles menores de 18 anos, com TFG <30 mL/min/1,73 m2 e/ou aqueles com dados ausentes. Foram acompanhados 70 pacientes. Resultados: Fatores independentemente associados aos desfechos renais foram: comprimento renal total - Razão de Risco (HR) ajustada com intervalo de confiança de 95% (IC 95%): 1,137 (1,057-1,224), taxa de filtração glomerular - HR (IC 95%): 0,970 (0,949-0,992) e nível sérico de ácido úrico - HR (IC 95%): 1,643 (1,118-2,415). Diabetes mellitus - HR (IC 95%): 8,115 (1,985-33,180) e TFG - HR (IC 95%): 0,957 (0,919-0,997) foram associados ao desfecho secundário. Conclusões: Esses achados corroboram a hipótese de que comprimento renal total, TFG e nível sérico de ácido úrico podem ser importantes preditores prognósticos de DRPAD em uma coorte brasileira, o que pode ajudar a selecionar pacientes que necessitam de acompanhamento mais próximo.

Secondary infections in critically ill patients admitted with COVID-19 in Bogotá, Colombia. Observational cohort study / Infecciones secundarias en pacientes críticos ingresados con COVID-19 en Bogotá, Colombia. Estudio observacional de cohorte

Abstract Introduction: The presence of secondary infections in critically ill patients and antibiotic resistance are often determining factors in the clinical evolution of these patients. Objective: To describe the pathogens isolated in blood cultures and tracheal secretion cultures in ICU patients with COVID-19 and to evaluate the association between the presence of secondary infections and 60-day mortality. Methods: Retrospective analytical cohort study conducted in 273 adults admitted to the ICU with COVID-19 at the Subred Integrada de Servicios de Salud del Sur - Hospital El Tunal, Bogotá, Colombia between April and December 2020. Data from records of blood or tracheal secretion cultures were collected. A bivariate analysis was performed using a Cox proportional-hazards regression model to assess the association between the development of secondary infections and 60-day mortality. Results: At least one positive blood culture was reported in 96/511 patients (18.8%). Of the 214 blood cultures performed within 48 hours after ICU admission, 7.7% were positive. A total of 127 germs were isolated from blood cultures - mostly gram-negative bacteria (61.4%) - followed by fungi (25.2%). Additionally, 39.5% were multidrug-resistant, and carbapenem resistance was the most common antibiotic resistance pattern (33.3% of all gram-negative bacteria isolates). Finally, in this cohort, the presence of secondary infections was not associated with 60-day mortality (HR: 1.012, 95%CI: 0.7211.420; p= 0.946). Conclusions: Although the prevalence of superinfection was moderately high, the prevalence of coinfection was low. Gram-negative bacteria were predominant, and almost one third of the germs were multidrug-resistant.

Resumen Introducción: La presencia de infecciones secundarias en pacientes críticos y la resistencia a los antibióticos suelen ser factores determinantes en la evolución clínica de estos pacientes. Objetivo: Describir los patógenos aislados en cultivos de sangre y de secreciones traqueales en pacientes de la UCI con COVID-19 y evaluar la relación entre la presencia de infecciones secundarias y la mortalidad a 60 días. Métodos: Estudio de cohorte analítico retrospectivo realizado en 273 adultos ingresados a la UCI con COVID-19 de la Subred Integrada de Servicios de Salud del Sur - Hospital El Tunal, Bogotá, Colombia entre abril y diciembre de 2020. Se obtuvieron los datos de los registros de cultivos en sangre y en secreciones de la tráquea. Se llevó a cabo un análisis bivariado mediante un modelo de riesgos proporcionales o regresión de Cox para evaluar la relación entre el desarrollo de infecciones secundarias y la mortalidad a 60 días. Resultados: Se reportó al menos un cultivo en sangre positivo en 96/511 (18.8%). De los 214 cultivos de sangre realizados dentro de las 48 horas siguientes al ingreso a la UCI, 7,7% resultaron positivos. Se aislaron en total 127 gérmenes en los cultivos en sangre, en su mayoría bacterias gramnegativas (61,4%) - seguido de hongos (25,2%). Adicionalmente, 39.5% fueron multirresistentes, siendo la resistencia los carbapenémicos el patrón de resistencia a los antibióticos más frecuente (33,3% de todos los aislados de bacterias gramnegativas). Finalmente, la presencia de infecciones secundarias en esta cohorte no se asoció con mortalidad a 60 días (HR: 1,012, IC 95%: 0,721-1,420; p= 0,946). Conclusiones: A pesar de que la prevalencia de super infecciones fue moderadamente alta, la prevalencia de coinfección fue baja. Las bacterias gramnegativas fueron las predominantes y casi un tercio de los gérmenes eran multirresistentes.

Clinicai characteristics and mortality in mechanically ventilated COVID-19 patients: prospective cohort study / Características clínicas y mortalidad en pacientes COVID-19 ventilados mecánicamente: estudio de cohorte prospectivo

Abstract Introduction: Factors associated with mortality among mechanically ventilated COVID-19 patients have been scarcely studied in Latin America. Objective: To identify factors associated with mortality in mechanically ventilated COVID-19 patients. Methods: This prospective study was undertaken in a single center between April and October 2020, recruiting COVID-19 patients managed with mechanical ventilation. We excluded patients who died within the first 24 hours after endotracheal intubation. Clinical characteristics, laboratory results, ventilation interventions, and outcomes were collected and compared between the deceased and surviving groups. The association between these factors and hospital death was examined, and relevant covariates were included in a multivariate logistic regression model. Results: A total of 273 patients were included (72.5% male), the mortality rate was 37% (95% CI 31% - 43%), and the median age was 63 years (IQR 52-72). The most frequent comorbidity was hypertension (45%). Factors associated with mortality were: older age (OR 1.08; 95% CI 1.051.11), male gender (OR 2.79; 95% CI 1.30-6.01), immunosuppression (OR 3.98; 95% CI 1.57-10.06), thrombocytopenia (OR 3.84; CI 95% 1.47-10.01), driving pressure (OR 1.20; 95% CI 1.07-1.34) and the use of dialysis (OR 4.94; 95% CI 2.56-9.51). Chronic hypertension (OR 0.35; 95% CI 0.17-0.71) and fever on admission (OR 0.51; 95% CI 0.27-0.98) were found to have a protective effect. Conclusions: Older age, male sex, immunosuppression, thrombocytopenia, increased driving pressure, use of dialysis, absence of fever, or arterial hypertension were associated with an increased risk of mortality among mechanically ventilated COVID-19 patients.

Resumen Introducción: Es poco lo que se han estudiado en América Latina los factores asociados con mortalidad en pacientes con COVID-19 ventilados mecánicamente. Objetivo: Identificar los factores asociados con mortalidad en pacientes con COVID-19 manejados con ventilación mecánica. Métodos: Este estudio prospectivo se adelantó en un solo centro entre los meses de abril y octubre de 2020 e incluyó pacientes con COVID-19 manejados con ventilación mecánica. Se excluyeron pacientes que fallecieron en las primeras 24 horas después de la intubación orotraqueal. Se recopilaron datos de las características clínicas, resultados de laboratorio, intervenciones ventilatorias y desenlaces, y se hizo una comparación entre el grupo de pacientes fallecidos y el grupo de sobrevivientes. Se examinó la asociación entre estos factores y la muerte intrahospitalaria, y las covariables relevantes se incluyeron en un modelo multivariable de regresión logística. Resultados: Se incluyó un total de 273 pacientes (72.5% hombres), la tasa de mortalidad fue del 37% (IC 95% 31% - 43%), la mediana de edad fue de 36 años (RIC 52-72) y la comorbilidad más frecuente fue la hipertensión (45%). Los factores asociados con mortalidad fueron: edad avanzada (OR 1.08; IC 95% 1.05-1.11), género masculino (OR 2.79; IC 95% 1.30-6.01), inmunosupresión (OR 3.98; IC 95% 1.57-10.06), trombocitopenia (OR 3.84; CI 95% 1.47-10.01), presión de distensión (OR 1.20; IC 95% 1.07-1.34) y el uso de diálisis (OR 4.94; IC 95% 2.56-9.51). La presencia de hipertensión (OR 0.35; IC 95% 0.17-0.71) y de fiebre (OR 0.51; IC 95% 0.27-0.98) al momento de la hospitalización demostraron tener un efecto protector. Conclusiones: Se encontró asociación entre la edad avanzada, el sexo masculino, la inmunosupresión, la trombocitopenia, una presión de distensión elevada, el uso de diálisis, la ausencia de fiebre o de hipertensión y un mayor riesgo de mortalidad en pacientes con COVID-19 ventilados mecánicamente.

COVID-19 y medidas de protección adoptadas en comunidades rurales amazónicas durante los primeros meses de la pandemia / COVID-19 and protection measures adopted in rural amazon communities during the first months of the pandemic

RESUMEN Objetivos. Analizar la evolución del COVID-19 en poblaciones rurales de Loreto y Ucayali en la etapa temprana de la pandemia. Materiales y métodos. Se realizó un estudio observacional longitudinal a nivel de comunidades basado en dos rondas de encuestas telefónicas con autoridades locales de más de 400 comunidades rurales indígenas y no-indígenas en Loreto y Ucayali, en julio y agosto de 2020, para recopilar información sobre casos y muertes por COVID-19 en sus comunidades, medidas de protección adoptadas y la recepción de asistencia estatal en la etapa temprana de la pandemia. Estadísticas descriptivas permiten evaluar la evolución de la pandemia después del brote inicial y comparar las tendencias de las dos regiones, así como entre poblaciones indígenas y no-indígenas. Resultados. En julio de 2020, el COVID-19 había llegado al 91,5% de las comunidades, aunque se reportaron muertes por COVID-19 en 13,0% de las comunidades, siendo la mortalidad rural mayor en Ucayali (0,111%) que en Loreto (0,047%) y en comunidades no-indígenas. Para agosto, la prevalencia disminuyó de 44,0% a 32,0% de comunidades, pero se volvió más frecuente en las comunidades indígenas, y aquellas en Ucayali. Viajar a la ciudad para recibir bonos estatales y las dificultades para mantener el distanciamiento social contribuyeron al contagio. Conclusiones. Los hallazgos mostraron la evolución del COVID-19 en comunidades rurales y señalan áreas importantes de atención en futuras políticas públicas, para la adopción de medidas de protección y reconsiderar estrategias para la distribución de asistencia ante pandemias futuras.

ABSTRACT Objectives. To analyze the evolution of COVID-19 in rural populations of Loreto and Ucayali in the early stage of the pandemic. Materials and methods. A community-level longitudinal observational study was conducted and based on two rounds of telephone surveys with local authorities of more than 400 indigenous and non-indigenous rural communities in Loreto and Ucayali, in July and August 2020. We collected information on cases and deaths by COVID-19 in their communities, protective measures adopted and if state assistance was received in the early stage of the pandemic. Descriptive statistics allowed us to evaluate the evolution of the pandemic after the initial outbreak and compare the trends of the two regions, as well as between indigenous and non-indigenous populations. Results. In July 2020, COVID-19 had reached 91.5% of the communities, although deaths from COVID-19 were reported in 13.0% of the communities, with rural mortality being higher in Ucayali (0.111%) than in Loreto (0.047%) and in non-indigenous communities. By August, prevalence decreased from 44.0% to 32.0% of communities, but became more frequent in indigenous communities, and those in Ucayali. Traveling to the city to receive state bonuses and difficulties maintaining social distancing contributed to the spread. Conclusions. Our findings show the evolution of COVID-19 in rural communities and point to important areas of attention in future public policies, for the adoption of protective measures and reconsidering strategies for the distribution of assistance in the face of future pandemics.

Las variantes axonales tuvieron un RR de 0,47 (IC95%: 0,24 a 0,92) para el requerimiento de VM en adultos, pero en niños fue de 1,68 (IC95%: 1,25 a 2,25). Hubo una alta heterogeneidad estadística. Conclusiones. Las variantes axonales tienen en promedio mayor tiempo de VM y de hospitalización, en total y por subgrupos. Se observó un mayor requerimiento de VM para las variantes axonales en niños; mientras que en los adultos fue menor.

ABSTRACT Objectives. To determine the requirement and time to mechanical ventilation and Intensive Care Unit (ICU), hospitalization and hospitalization time, death and disability of the axonal variants of Guillain-Barré Syndrome (GBS) in comparison with the acute demyelinating variant in patients of all the ages. Materials and methods. The systematic review that included patients with GBS. The exposure variable was the axonal variants and the comparator was acute inflammatory demyelinating polyneuropathy (AIDP). The outcomes were the requirement and time on mechanical ventilation (MV), requirement and time in the ICU, hospitalization time, disability and death. The NewCasttle-Ottawa Scale (NOS) was used to assess risk of bias. A meta-analysis was conducted to calculate mean differences and relative risks (RR) with their 95% confidence intervals (CI) using inverse variances and random effects models. Results. Of the 3116 articles found, 46 met the selection criteria. The time on MV was 7.42 days (95% CI: 0.36 to 1.48) and the hospitalization time was 3.11 (95% CI: 0.73 to 5.49) days for the axonal variants. The axonal variants had a RR of 0.47 (95% CI: 0.24 to 0.92) for the requirement of MV in adults, but it was 1.68 (95% CI: 1.25 to 2.25) in children. There was a high statistical heterogeneity. Conclusions. Axonal variants showed, on average, longer MV and hospitalization time, overall and by subgroups. A high MV requirement was found for axonal variants in children; it was lower for adults.

Fatores preditivos da permanência em uma Unidade de Queimados / Factors predicting burn unit length-of-stay

Introdução: A taxa de mortalidade em pacientes queimados diminuiu significativamente, tornando importante avaliar outros desfechos, como o tempo de internação, que aumenta a morbidade física e psicológica, o risco de infecção hospitalar e os custos financeiros. O objetivo deste estudo é analisar a relevância de vários fatores no tempo de internação na Unidade de Queimados. Método: Foram incluídos neste estudo 711 pacientes admitidos entre 2011 e 2020 na Unidade de Queimados do Hospital de São José, Centro Hospitalar Lisboa Central, Lisboa, Portugal. Os dados coletados foram analisados utilizando o PSPP para Windows. Resultados: Os pacientes eram predominantemente do sexo masculino, com idade média de 54 anos. O tempo médio de permanência hospitalar foi de 29 dias. Os fatores que prolongaram a estadia hospitalar foram relacionados à gravidade da queimadura, ao número de cirurgias e ao tempo decorrido até a primeira cirurgia, valores laboratoriais alterados tanto no perfil hematológico quanto químico durante a hospitalização, e a presença e o número de infecções documentadas. Conclusão: Existem fatores potencialmente modificáveis que infiuenciam o tempo de permanência hospitalar. Nosso estudo nos permite concluir que o tempo decorrido até a primeira intervenção cirúrgica e a presença e o número de infecções documentadas prolongam significativamente esse desfecho, e ênfase deve ser dada à implementação de medidas que favoreçam a intervenção cirúrgica precoce e o controle rigoroso de infecções.

Introduction: Burn patients' mortality rate has decreased significantly, making it important to evaluate other outcomes, such as length-of-stay, which increases physical and psychological morbidity, risk of nosocomial infection, and financial costs. The objective of this study is to analyze the relevance of several factors in the Burn Unit length-of-stay. Material and Methods: 711 patients were included in this study, admitted between 2011 and 2020 to the Burn Unit at São José Hospital, Centro Hospitalar Lisboa Central, Lisbon, Portugal. Collected data was analyzed using PSPP for Windows. Results: Patients included in the study were predominantly males, with a mean age of 54 years. The mean length of stay was 29 days. The factors that prolonged in-hospital stay were those related to the severity of the burn, the number of surgeries and the time elapsed until the first one, altered laboratory values in both hematologic and chemistry profile during the hospitalization, and the presence and number of documented infections. Conclusion: There are potentially modifiable factors that influence length-of-stay. Our study allows us to conclude that the time elapsed until the first surgical intervention and the presence and number of documented infections significantly prolong this outcome, and emphasis should be given to the implementation of measures that favor early surgical intervention and strict infection control.

Complicaciones quirúrgicas: un tema complicado / Surgical complications: A complicated topic

Introducción. Las complicaciones quirúrgicas son un tema relevante, difícil de abordar e inmerso en una cultura punitiva y vergonzosa hacia el médico. La ausencia de una medición sistemática, confiable y socializada es un desafío para los servicios quirúrgicos. El desconocimiento de las medidas de frecuencia y el impacto de las complicaciones quirúrgicas en las instituciones, y a su vez, dentro de los servicios quirúrgicos, evidencia la necesidad de abordar el tema desde una perspectiva de mejoramiento continuo. Métodos. Se hizo un análisis crítico y reflexivo sobre la conceptualización de las complicaciones quirúrgicas, los avances en su proceso de evaluación y su utilidad como indicador de calidad en los servicios quirúrgicos. Se ilustraron las metodologías con ejemplos clínicos que facilitan su entendimiento y aplicabilidad. Resultados. El trabajo inicial de los doctores Clavien & Dindo se ha fortalecido al considerar integralmente el proceso de atención quirúrgica como un indicador de calidad de la atención en salud. El desarrollo del Índice Integral de Complicaciones (CCI), para los eventos en el período posoperatorio, representa un paso adicional en el abordaje del problema. Su potencialidad en el análisis de los eventos ofrece una oportunidad para la implementación y la investigación en el tema. Conclusiones. Las complicaciones quirúrgicas representan un indicador robusto que permite evaluar el desempeño individual y grupal en un servicio quirúrgico. Hay metodologías recientes que deben ser incorporadas en la actividad asistencial de los cirujanos. Representan un insumo en la educación médica a todo nivel e, igualmente, un elemento de crecimiento personal y académico para todo cirujano.

Introduction. Surgical complications are a relevant topic, difficult to address and immersed in a punitive and shameful culture towards the doctor. The absence of systematic, reliable, and socialized measurement is a challenge for surgical services. The lack of knowledge of frequency measurements and the impact of surgical complications in institutions, and in turn, within surgical services, shows the need to address the issue from a perspective of continuous improvement. Methods. A critical and reflective analysis was carried out on the conceptualization of surgical complications, the advances in their evaluation process and their usefulness as an indicator of quality in surgical services. The methodologies were illustrated with clinical examples that facilitate their understanding and applicability. Results. The initial work of doctors Clavien & Dindo has been strengthened by comprehensively considering the surgical care process as an indicator of quality of health care. The development of the Comprehensive Complication Index (CCI), for events in the postoperative period, represents an additional step in addressing the problem. Its potential in the analysis of events offers an opportunity for implementation and research on the topic. Conclusions. Surgical complications represent a robust indicator that allows evaluating individual and group performance in a surgical service. There are recent methodologies that must be incorporated into the care activity of surgeons. They represent an input in medical education at all levels and equally, an element of personal and academic growth for every surgeon.

Complicaciones vasculares postrasplante hepático, una situación con alta morbimortalidad / Vascular complications after liver transplantation: A complication with high morbidity and mortality

Introducción. El trasplante hepático es el tratamiento indicado en aquellas enfermedades del hígado en las cuales ya se han agotado otras medidas terapéuticas, y es un procedimiento complejo. Las complicaciones postquirúrgicas se relacionan con alta morbimortalidad y pueden llevar a desenlaces fatales; las complicaciones vasculares son las de mayor mortalidad, por lo que es crucial la detección temprana y el tratamiento oportuno. El objetivo de este estudio fue caracterizar los pacientes que presentaron complicaciones vasculares posterior a trasplante hepático. Métodos. Estudio descriptivo, retrospectivo, con seguimiento a los pacientes sometidos a trasplante hepático en la Fundación Cardiovascular, entre los años 2013 y 2023, que presentaron complicaciones vasculares. Se evaluó el tipo de complicación, los factores de riesgo y los desenlaces postquirúrgicos. Resultados. Se incluyeron en total 82 pacientes trasplantados, con un predominio del sexo masculino 59,8 % (n=49); la principal indicación del trasplante fue el alcoholismo (21,9 %). Veinte pacientes presentaron complicaciones vasculares; la más frecuente fue trombosis de arteria hepática, en el 45 % (n=9). En tres de estos casos se requirió nuevo trasplante. Conclusión. Las complicaciones vasculares empeoran la evolución clínica postoperatoria de los pacientes y están relacionadas con alta morbimortalidad, por lo cual es crucial la valoración multidisciplinaria, el diagnóstico oportuno y la intervención temprana para disminuir los desenlaces fatales.

Introduction. Liver transplant is the treatment indicated for those liver diseases in which other therapeutic measures have already been exhausted, and it is a complex procedure. Post-surgical complications are related to high morbidity and mortality and can lead to fatal outcomes. Vascular complications are the ones with the highest mortality, so early detection and timely treatment are crucial. The objective of this study was to characterize patients who presented vascular complications after liver transplantation. Methods. Descriptive, retrospective study, with follow-up of patients undergoing liver transplant at the Fundación Cardiovascular, between 2013 and 2023, who presented vascular complications. The type of complication, risk factors and postsurgical outcomes were evaluated. Results. A total of 82 transplant patients were included, with a predominance of males with 59.8% (n=49); the main indication for transplant was alcoholism (21.9%). Twenty patients presented vascular complications; the most frequent was hepatic artery thrombosis 45% (n=9). In three of these cases a new transplant was required. Conclusion. Vascular complications worsen the postoperative clinical course of patients and are associated with high morbidity and mortality, which is why multidisciplinary assessment, diagnosis and early intervention are crucial to reduce fatal outcomes.

ARGEN-IAM-ST: adultos mayores con infarto, ¿son todos iguales? / ARGEN-IAM-ST Registry: older adults with infarction: Are they all the same?

Resumen Introducción : Actualmente se define al paciente como adulto mayor (AM) si su edad es al menos de 60 años. Dada la expectativa de vida prolongada resulta intere sante evaluar si todos los AM con infarto agudo de mio cardio (IAM) son iguales. Los objetivos fueron conocer la prevalencia de AM en el IAM y dentro de ellos, la de los ≥75 años y analizar características, tratamientos de reperfusión y mortalidad intrahospitalaria de acuerdo a si son < o ≥ 75 años. Métodos : Se analizaron los pacientes AM ingresados en el Registro Nacional de Infarto con supra desnivel del segmento ST (ARGEN-IAM-ST). Se los dividió en grupo 1: 60-74 años y grupo 2: ≥ 75 años y se compararon entre sí. Resultados : AM 3626, 75.92% del Grupo 1, el resto del Grupo 2. En el grupo 2 hubo más mujeres, hipertensos y con antecedentes coronarios. Hubo similar porcentaje de diabetes y dislipidemia, pero menos de tabaquistas. En el Grupo 2 se empleó menos tratamiento de reperfusión (aunque más angioplastia primaria), con similar tiempo puerta-balón. Los pacientes del Grupo 2 recibieron me nos medicamentos de probada eficacia y en la evolución hospitalaria, más sangrado (aunque no mayor), más insuficiencia cardíaca y más mortalidad: 18.3% vs 9.4%, p<0.001. La edad ≥75 años fue predictor independiente de mortalidad. Conclusiones : Uno de cada cuatro AM con IAM tiene más de 75 años; estos pacientes reciben menos reper fusión, presentan más insuficiencia cardíaca y sangrado y tienen el doble de mortalidad que los pacientes de entre 60 y 74 años.

Abstract Introduction : Currently the patient is defined as an older adult (OA) when the age is at least 60 years. Given the long life expectancy, it is interesting to evaluate whether all OAs with acute myocardial infarction (AMI) are equal. The objectives were to know the prevalence of OA in AMI and within them, that of those ≥75 years of age and to analyze characteristics, reperfusion treat ments and in-hospital mortality according to whether they are < or ≥ 75 years of age. Methods : OA patients admitted to the National Reg istry of Infarction with ST segment elevation (ARGEN-IAM-ST) were analyzed. They were divided into group 1: 60-74 years old and group 2: ≥ 75 years old and compared with each other. Results : 3626 AM, 75.9% from Group 1, the rest from Group 2. In group 2 there were more women, hyperten sive and with a history of coronary arteries. There was a similar percentage of diabetes and dyslipidemia, but fewer of smokers. In Group 2, less reperfusion treat ment was used (although more primary angioplasty), with similar door-to-balloon time. Patients in Group 2 received fewer medications of proven efficacy and in the hospital course, they had more bleeding (although not major), more heart failure and more mortality: 18.3% vs. 9.4%, p<0.001. Age ≥75 years was an independent predictor of mortality. Conclusions : one in four patients with AMI is over 75 years old; they receive less reperfusion, have more heart failure, bleeding and twice the mortality rate than patients between 60 and 74 years.

Exceso de muertes en argentina durante la pandemia por COVID-19: análisis de la mortalidad entre 2020 y 2022 / Excess deaths in Argentina during the COVID-19 pan demic: analysis of mortality between 2020 and 2022

Resumen Los reportes del exceso de mortalidad durante la pandemia por COVID-19 en Argentina han sido parcia les y fragmentados hasta el momento. Este estudio se propuso cuantificar el exceso de muertes y explorar su distribución demográfica, temporal y geográfica durante el periodo 2020-2022. Utilizando datos de 1 192 963 registros de muertes de estadísticas vitales y proyecciones poblacionales, se estimó la mortalidad esperada mediante modelos de regresión. El exceso de muertes se calculó como la diferencia entre la mortalidad observada y la esperada. Se estimó un exceso de 160 676 muertes (IC 95% 146 861 a 174 491), representando una tasa de 116.9 muer tes (IC 95% 115.5 a 118.3) adicionales por cada 100 000 personas-año. Se verificó una significativa heterogenei dad entre las distintas provincias argentinas. Los resultados indican un impacto desigual de la pandemia, con mayores tasas de exceso de mortalidad en algunas regiones y grupos de edad más vulnerables. Estos patrones sugieren la necesidad de estrategias diferenciadas de respuesta sanitaria y apoyo a las poblaciones más vulnerables en escenarios de nuevas epidemias.

Abstract Reports of excess mortality during the COVID-19 pan demic in Argentina have been partial and fragmented so far. This study aimed to quantify excess deaths and explore their demographic, temporal, and geographic distribution during the period 2020-2022. Using data from 1 192 963 death records from vital statistics and population projections, expected mortality was estimated using regression models. Excess death was calculated as the difference between observed and expected mortality. An excess of 160 676 deaths (95% CI 146 861 to 174 491) was estimated, representing a rate of 116.9 (95% CI 115.5 to 118.3) additional deaths per 100 000 person-years. Significant heterogeneity was found among the different argentine provinces. The results indicate an uneven impact of the pan demic, with higher excess mortality rates in some re gions and more vulnerable age groups. These patterns suggest the need for differentiated strategies of health care response and support to the most vulnerable popu lations in scenarios of new epidemics.

¿Tienen los pacientes con tromboembolismo pulmonar agudo y un puntaje PESI (Índice de Severidad del Embolismo Pulmonar) intermedio o alto, asociado a cáncer activo, un mayor riesgo de presentar una evolución desfavorable respecto de aquellos sin cáncer? / Do Patients with Acute Pulmonary Embolism and an Intermediate or High PESI (Pulmonary Embolism Severity Index) Score Associated with Active Cancer Have Higher Risk of an Unfavorable Progression Versus Those Without Cancer?

RESUMEN Introducción: El Índice de Severidad del Embolismo Pulmonar (PESI) se utiliza para categorizar el riesgo de mortalidad en el tromboembolismo pulmonar agudo (TEP). Por definición, los pacientes con cáncer siempre presentarán un puntaje PESI simplificado alto y serán considerados de mayor riesgo. Existe información limitada respecto de si los pacientes con PESI intermedio o alto (≥86 puntos) y cáncer activo, tienen mayor riesgo de presentar una evolución desfavorable respecto de aquellos sin cáncer. Objetivos: Determinar si, en pacientes con TEP y un puntaje PESI ≥86 puntos, la presencia de cáncer activo se asocia a una evolución desfavorable respecto de aquellos sin cáncer. Material y métodos: Análisis retrospectivo en pacientes con TEP y un puntaje PESI ≥86, entre los años 2008 y 2022. Se evaluó la ocurrencia de muerte intrahospitalaria (MIH), uso de drogas vasopresoras (DV) y necesidad de asistencia respiratoria mecánica (ARM) en los pacientes con vs. sin cáncer. Resultados: Se analizaron 209 pacientes. La población con cáncer, respecto de aquella sin cáncer, resultó ser más joven (65 vs. 70 años; p=0,006), presentó valores de PESI simplificado altos con mayor frecuencia (100 % vs. 84 %; p<0,001), tuvo menor requerimiento de ARM (9 % vs. 34 %; p=0,005) y menor uso de DV (11 % vs. 23 %; p=0,019), aunque no se observaron dife rencias en las tasas de MIH (12,7 % vs. 8 %; p=NS). Conclusiones: Los pacientes con TEP y un puntaje PESI ≥86 con cáncer no presentaron mayor MIH e incluso tuvieron menor requerimiento de ARM y DV. En la población estudiada, los pacientes con TEP y cáncer no tuvieron mayor riesgo de presentar una evolución desfavorable.

ABSTRACT Background: The Pulmonary Embolism Severity Index (PESI) is used to categorize the risk of death in acute pulmonary em bolism (PE). By definition, cancer patients will always have a high simplified PESI score and will be considered at high risk. There is limited information regarding whether patients with an intermediate or high PESI score (≥86 points) and cancer are at greater risk of an unfavorable progression versus those without cancer. Objectives: To determine whether the presence of active cancer in patients with a PESI score ≥86 points is associated with an unfavorable progression versus those without cancer. Methods: A retrospective analysis in patients with PE and a PESI score ≥86, between 2008 and 2022. The occurrence of in-hospital mortality (IHM) the use of vasopressor drugs (VDs), and the need for mechanical ventilatory support (MVS) were evaluated in patients with vs. without cancer. Results: 209 patients were analyzed. The population with cancer was younger than patients without cancer (65 vs 70 years; p=0.006), showed high simplified PESI values more frequently (100% vs 84%; p<0.001), had lower MVS requirement (9% vs 34%; p=0.005), and used fewer VDs (11% vs 23%; p=0.019). However, no difference was observed in IHM rates (12.7% vs 8%; p=NS). Conclusions: Patients with PE and a PESI score ≥86 who have cancer did not show higher IHM and also had lower MVS and VDs requirement. Therefore, in the studied population, patients with PE and cancer had no greater risk of having an unfavorable progression.

Epidemiología del trauma de alta energía en Chile: análisis ecológico con registros públicos / Epidemiology of high-energy trauma in Chile: An ecological analysis using public registries

El trauma de alta energía se define como lesiones orgánicas graves resultantes de eventos que generan una gran cantidad de energía cinética, eléctrica o térmica. Constituye una importante preocupación de salud pública, representando el 10% de la mortalidad mundial. El objetivo de este artículo es describir la epidemiología del trauma de alta energía en Chile. Específicamente, se busca comparar la tasa de mortalidad por 100 000 habitantes entre los países miembros de la Organización Mundial de la Salud (OMS), realizar un análisis descriptivo de las notificaciones por Garantías Explícitas en Salud (GES) del problema de salud "politraumatizado", y analizar la tendencia de la tasa de fallecidos por causa externa en Chile. El presente estudio tiene un diseño ecológico, utilizando tres bases de datos de acceso abierto. Primero, se utilizó la base de datos de la OMS sobre fallecidos por accidentes automovilísticos en 2019. Luego, se consultó la base de datos del programa Garantías Explícitas en Salud para el problema "politraumatizado" entre los años 2018 y 2022. Finalmente, se utilizó la base de datos del Departamento de Estadísticas de Salud de Chile sobre causas de muerte entre 1997 y 2020. En 2019, Chile ocupó una posición intermedia en cuanto a la tasa de mortalidad por 100 000 habitantes debido a accidentes de tráfico. Las notificaciones el programa Garantías Explícitas en Salud por politraumatismo fueron predominantemente en hombres de entre 20 y 40 años, afiliados al sistema de salud pública. Por este motivo, el foco principal de prevención debe centrarse en este grupo. La mortalidad por accidentes mostró una tendencia decreciente, identificándose cambios estructurales significativos en los años 2000 y 2007.

High-energy trauma is defined as severe organic injuries resulting from events that generate a large amount of kinetic, electrical, or thermal energy. It represents a significant public health concern, accounting for 10% of global mortality. This article aims to describe the epidemiology of high-energy trauma in Chile. Specifically, it seeks to compare the mortality rate per 100 000 inhabitants among member countries of the World Health Organization (WHO), provide a descriptive analysis of notifications under the Explicit Health Guarantees (GES) for the health issue of polytraumatized patients, and analyze the trend in the mortality rate due to external causes in Chile. This study employs an ecological design using three open-access databases. First, the WHO database on deaths from traffic accidents in 2019 was used. Then, the GES database was consulted for the "Polytraumatized" issue between 2018 and 2022. Finally, the Chilean Department of Health Statistics database on causes of death between 1997 and 2020 was utilized. In 2019, Chile ranked in the middle regarding the mortality rate per 100 000 inhabitants due to traffic accidents. GES notifications for polytrauma predominantly involved men aged 20 to 40 years and those affiliated with the public health system, highlighting a primary focus for prevention efforts. Mortality from accidents showed a decreasing trend, with significant structural changes identified in 2000 and 2007.

Resultados: Se analizaron los datos de 1598 pacientes con IRAG, 820 varones (51,3%), 875 (54,8%) con 60 o más años, 1054 (66,0%) del departamento Central. El 79.2% (n=1265) de los pacientes presentaba algún factor de riesgo de gravedad o comorbilidad, 764 (47,8%) con hipertensión arterial. El 38.5% (n=632) fue admitido a UCI y la mortalidad fue de 34,7% (n=554). En el 13,8% (n=353) se confirmó SARSCoV-2, rhinovirus (1,7%), influenza A (1,5%), influenza B (0,6%), parainfluenza 3 (0,6%), VSR (0,2%), bocavirus (0,4%) e influenza AH1N1 (0,6%). Hubo significativamente mayor frecuencia de fallecidos en los de 60 años y más (40,7%), con algún factor de riesgo de gravedad (35,5% vs 25,9%) y en los confirmados con COVID-19 (38,2% vs 30,5%). Discusión: SARSCoV-2 sigue siendo el agente etiológico principal de las IRAG. El conocimiento de la epidemiología y los agentes virales es crucial para desarrollar estrategias de prevención y terapéuticas efectivas.

Introduction: Sentinel Surveillance of Severe Acute Respiratory Infections (SARI) includes the monitoring and characterization of hospitalized cases. Objective: To describe the clinical-epidemiological characteristics and etiological agents of adults with SARI in a sentinel hospital in Paraguay. Methodology: Observational, descriptive, cross-sectional study, with retrospective data collection, of adult patients with SARI hospitalized at the National Hospital of Itauguá between June 2022 and August 2023. The information was taken from the database of the National System of Epidemiological surveillance. Results: The data of 1598 patients with SARI were analyzed, 820 men (51.3%), 875 (54.8%) aged 60 or older, 1054 (66.0%) from the Central department. 79.2% (n=1265) of patients had some risk factor or comorbidity, 764 with hypertension (47.8%). 38.5% (n=632) were admitted to the ICU and mortality was 34.7% (n=554). SARSCoV-2 was confirmed in 13.8% (n=353), rhinovirus (1.7%), influenza A (1.5%), influenza B (0.6%), parainfluenza 3 (0.6%), RSV (0.2%), bocavirus (0.4%) and Influenza AH1N1 (0.6%). There was a significantly higher frequency of deaths in those aged 60 years and over (40.7%), with some risk factor (35.5% vs 25.9%), and in those confirmed with covid-19 (38.2% % vs 30.5%). Discussion: SARSCoV-2 continues to be the main etiological agent of SARI in a sentinel hospital in Paraguay. Continued knowledge of the epidemiology and viral agents involved is crucial to developing effective prevention and treatment strategies.
