ABSTRACT
RESUMO Objetivo: Investigar a aplicabilidade do Índice de Oxigenação Respiratória para identificar o risco de falha de cânula nasal de alto fluxo em pacientes com pneumonia. Métodos: Este estudo retrospectivo observacional de 2 anos foi realizado em um hospital de referência em Bogotá, na Colômbia. Incluíram-se no estudo todos os pacientes em que foi utilizada cânula nasal de alto fluxo pós-extubação como terapia-ponte para a extubação. O Índice de Oxigenação Respiratória foi calculado para avaliar o risco de falha pós-extubação de cânula nasal de alto fluxo. Resultados: Incluíram-se no estudo 162 pacientes. Destes, 23,5% apresentaram falha de cânula nasal de alto fluxo. O Índice de Oxigenação Respiratória foi significativamente menor em pacientes que tiveram falha de cânula nasal de alto fluxo. A mediana (IQ 25 - 75%) foi de 10,0 (7,7 - 14,4) versus 12,6 (10,1 - 15,6), com p = 0,006. O Índice de Oxigenação Respiratória > 4,88 apresentou razão de chances bruta de 0,23 (IC95% 0,17 - 0,30) e RC ajustada de 0,89 (IC95% 0,81 - 0,98) estratificada por gravidade e comorbidade. Após a análise de regressão logística, o Índice de Oxigenação Respiratória apresentou razão de chances ajustada de 0,90 (IC95% 0,82 - 0,98; p = 0,026). A área sob a curva Receiver Operating Characteristic para falha de extubação foi de 0,64 (IC95% 0,53 - 0,75; p = 0,06). O Índice de Oxigenação Respiratória não apresentou diferenças entre pacientes que sobreviveram e que morreram durante internação na unidade de terapia intensiva. Conclusão: O Índice de Oxigenação Respiratória é uma ferramenta acessível para identificar pacientes em risco de falha no tratamento pós-extubação com cânulas nasais de alto fluxo. Estudos prospectivos são necessários para ampliar a utilidade nesse cenário.
ABSTRACT Objective: To investigate the applicability of the Respiratory Rate-Oxygenation Index to identify the risk of high-flow nasal cannula failure in post-extubation pneumonia patients. Methods: This was a 2-year retrospective observational study conducted in a reference hospital in Bogotá, Colombia. All patients in whom post-extubation high-flow nasal cannula therapy was used as a bridge to extubation were included in the study. The Respiratory Rate-Oxygenation Index was calculated to assess the risk of post-extubation high-flow nasal cannula failure. Results: A total of 162 patients were included in the study. Of these, 23.5% developed high-flow nasal cannula failure. The Respiratory Rate-Oxygenation Index was significantly lower in patients who had high-flow nasal cannula failure [median (IQR): 10.0 (7.7 - 14.4) versus 12.6 (10.1 - 15.6); p = 0.006]. Respiratory Rate-Oxygenation Index > 4.88 showed a crude OR of 0.23 (95%CI 0.17 - 0.30) and an adjusted OR of 0.89 (95%CI 0.81 - 0.98) stratified by severity and comorbidity. After logistic regression analysis, the Respiratory Rate-Oxygenation Index had an adjusted OR of 0.90 (95%CI 0.82 - 0.98; p = 0.026). The area under the Receiver Operating Characteristic curve for extubation failure was 0.64 (95%CI 0.53 - 0.75; p = 0.06). The Respiratory Rate-Oxygenation Index did not show differences between patients who survived and those who died during the intensive care unit stay. Conclusion: The Respiratory Rate-Oxygenation Index is an accessible tool to identify patients at risk of failing high-flow nasal cannula post-extubation treatment. Prospective studies are needed to broaden the utility in this scenario.
ABSTRACT
Resumen Introducción: la diabetes mellitus tipo 2 (DM2) es el tipo más común de diabetes la cual ocurre generalmente en adultos, sin embargo, hay reportes que la describen en adolescentes y adultos jóvenes. Objetivo: describir las características clínicas y el tratamiento de la diabetes tipo 2 en adultos jóvenes en un hospital colombiano. Material y métodos: estudio de corte transversal entre el 2017 y 2019, que incluyó pacientes adultos jóvenes entre 18 y 40 años con DM2, que fueron atendidos en el Hospital Santa Mónica de Dosquebradas, Colombia. La unidad de análisis fueron las historias clínicas. Se incluyeron variables sociodemográficas, clínicas, farmacológicas y control metabólico (HbAlc < 7.0%). Se realizaron análisis descriptivos y se aplicó una regresión logística binaria (p< 0.05). Resultados: se identificaron 124 pacientes de los cuales 83 (70.0%) cumplieron criterios de inclusión, con una edad media de 33.7 ± 5.3 años. Unos 28 pacientes eran obesos (33.7%). Además, 21 pacientes (25.3%) presentaron control metabólico. Los fármacos más usados fueron metformina en 64 pacientes (77.1%), seguido de las insulinas en 46 pacientes (55.4%). Se estableció que 51 de estos (61.4%) presentaron adherencia al tratamiento. No hubo pacientes con terapia triple como estrategia terapéutica. Los pacientes con retinopatía diabética presentaban una probable asociación con tener control de la enfermedad en el momento del estudio (P=0.048, OR:0.130; IC95%:0.017-0.987). Conclusiones: los pacientes adultos jóvenes presentan pobre control metabólico y uso frecuente de insulinas. (Acta Med Colomb 2021; 46. DOI: https://doi.org/10.36104/amc.2021.1902).
Abstract Introduction: type 2 diabetes mellitus (T2DM) is the most common type of diabetes, generally occurring in adults. However, there are reports which describe it in adolescents and young adults. Objective: to describe the clinical characteristics and treatment of type 2 diabetes in young adults in a Colombian hospital. Materials and methods: a cross-sectional study from 2017 to 2019 which included young adult patients between 18 and 40 years old with T2DM who were seen at Hospital Santa Mónica in Dosquebradas, Colombia. The unit of analysis was the medical charts. Sociodemographic, clinical, pharmacological and metabolic control (HbA1c < 7.0%) variables were included. Descriptive analyses were performed, and binary logistic regression was applied (p<0.05). Results: 124 patients were identified, 83 (70.0%) of whom met the inclusion criteria, with a mean age of 33.7 ± 5.3 years. Some 28 patients were obese (33.7%). In addition, 21 patients (25.3%) had metabolic control. The most frequently used medications were metformin in 64 patients (77.1%), followed by insulin in 46 patients (55.4%). It was determined that 51 of these patients (61.4%) were compliant with treatment. No patients received triple therapy as a therapeutic strategy. Patients with diabetic retinopathy had a probable association with having the disease controlled at the time of the study (P=0.048, OR:0.130; 95%CI:0.017-0.987). Conclusions: young adult patients have poor metabolic control and frequent use of insulins. (Acta Med Colomb 2021; 46. DOI: https://doi.org/10.36104/amc.2021.1902).
ABSTRACT
Resumen Introducción: Los microorganismos capaces de producir carbapenemasas vienen incrementándose a nivel mundial y se han convertido en un problema de salud pública global. En Colombia actualmente la resistencia a carbapenémicos en las unidades de cuidado intensivo está aumentando y se desconoce su impacto en desenlaces clínicos. Objetivos: Determinar las características demográficas, clínicas, y los desenlaces de los pacientes adultos en estado crítico con infección por microorganismos productores de carbapenemasas en una unidad de cuidado intensivo polivalente de una institución de alta complejidad. Métodos: Estudio observacional, descriptivo y retrospectivo, incluyendo pacientes con infección por bacterias resistentes a carbapenémicos, ingresados a la unidad de cuidado intensivo entre el 1 de Enero de 2014 y el 1 de Enero de 2018. Se excluyeron los pacientes colonizados. Se evaluaron complicaciones clínicas, estancia en UCI y hospitalaria, así como la mortalidad en UCI y hospitalaria. Resultados: Se incluyó 58 pacientes. La mortalidad global fue de 67,2%, de los cuales 55,17% murió durante su estancia en la unidad de cuidado intensivo y 12.06% en hospitalización. La mediana de estancia en la unidad de cuidado intensivo fue de 18 días (RIQ 4-28). La causa más frecuente de mortalidad fue choque séptico en 51% y las complicaciones más comunes fueron lesión renal aguda y delirium en un 55,2% y 43,1%, respectivamente. La mediana de estancia en la UCI fue de 18 días (RIQ 4-28). Conclusiones: Las infecciones por bacterias resistentes a carbapenémicos en pacientes críticamente enfermos se relacionan con altas tasas de mortalidad, complicaciones y estancia prolongada en UCI
Abstract Introduction: Microorganisms able to produce carbapenemases are spreading worldwide and have become a concerning global public-health problem. In Colombia, the Gram-negative resistance to carbapenems at intensive care units is currently increasing and its impact on clinical outcomes is not well known. Objectives: To determine the demographic, clinical characteristics and outcomes of critically ill adult patients with infection by carbapenemase producing bacteria in a polyvalent intensive care unit of a highly complex institution. Methods: Single-center retrospective, descriptive observational study including critically ill adult patients infected by carbapenemase-producing bacteria and transferred to a polyvalent intensive care unit from January 1th 2014 to January 1th 2018. Known colonized patients were excluded. Clinical complications, ICU and in-hospital days of stay were evaluated, as ICU and in-hospital mortality. Results: A total of 58 patients were included. Overall mortality was 67.2%, of which 55.17% died during their stay in the intensive care unit and 12.06% in hospitalization. The median stay in the intensive care unit was 18 days (IQR 4-28). The most frequent cause of death was septic shock in 51% and the most common complications were acute renal injury and delirium in 55.2% and 43.1%, respectively. The median stay in the ICU was 18 days (RIQ 4-28). Conclusions: Infections caused by carbapenem-resistant bacteria in critically ill patients are associated with high mortality rates, complications and long stay in ICU.
