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. En mujeres, el riesgo de desarrollar enfermedad tromboembólica venosa (ETV) es 5 a 6 veces mayor durante el embarazo, riesgo que puede aumentar considerablemente si existen antecedentes personales o familiares de otros estados protrombóticos. La ETV es una de las principales causas de morbimortalidad en esta población, por lo que para evaluar la pertinencia de usar tromboprofilaxis, ya sea farmacológica o no farmacológica, es necesario reconocer oportunamente los factores de riesgo clínico asociados a esta condición. Objetivo. Describir el uso de pruebas de tamizaje de estados protrombóticos y de la tromboprofilaxis farmacológica y no farmacológica para prevenir la ETV durante la gestación, durante el parto y durante el puerperio. Materiales y métodos. Se realizó una revisión de la literatura en Embase, ClinicalKey, ScienceDirect, Access Medicine, Scopus, ProQuest, PubMed y LILACS. Se buscaron estudios sobre trombofilia y tromboprofilaxis en el embarazo publicados entre enero de 2004 y marzo de 2018 en inglés y en español. Resultados. En la búsqueda inicial se identificaron 126 artículos, de los cuales 52 cumplieron los criterios de inclusión. La mayoría de estudios correspondió a revisiones narrativas (n = 15), revisiones sistemáticas (n=8) y guías de práctica clínica (n=6). Conclusión. Se recomienda el uso de pruebas de tamizaje de estados protrombóticos durante la gestación, el parto y el puerperio, ya que la identificación oportuna de la ETV permite disminuir las tasas de morbimortalidad en esta población mediante la implementación de medidas tromboprofilácticas, sean o no farmacológicas.
Abstract Introduction: The risk of developing venous thromboembolism (VTE) in women is 5 to 6 times higher during pregnancy. In addition, this risk can be significantly higher if the patient has a history or family history of hypercoagulate states. VTE is a leading cause of morbidity and mortality in this population, so in order to assess if it is appropriate to use thromboprophylaxis during pregnancy, whether pharmacological or non-pharmacological, it is necessary to timely recognize the clinical risk factors associated with this condition. Objective: To describe the use, on the one hand, of screening tests for hypercoagulate states and, on the other, of pharmacological and non-pharmacological thromboprophylaxis to prevent the development of VTE during pregnancy, labor and the puerperium Materials and methods: A literature review was conducted in the Embase, ClinicalKey, ScienceDirect, Acces Medicine, Scopus, ProQuest, PubMed and LILACS databases. The search included studies on thrombophilia and thrombophylaxis during pregnancy published in English or Spanish between January 2004 and March 2018. Results: After completing the initial search, 126 studies were identified, of which 52 met the inclusion criteria. Most studies were narrative reviews (n = 15), systematic reviews (n = 8) and clinical practice guidelines (n=6). Conclusion: The use of screening tests for hypercoagulate states during pregnancy, labor and the puerperium is recommended, since the timely identification of VTE will allow the reduction of morbidity and mortality rates in this population through the implementation of thromboprophylactic measures, whether they are pharmacological or non-pharmacological.
ABSTRACT
La obesidad y sus complicaciones constituyen una de las principales pandemias a nivel mundial, en especial la Diabetes tipo 2 que está asociada a la resistencia a la insulina. El propósito de este trabajo es describir la relación existente entre la obesidad y otros de factores de riesgo cardiovascular en una población de estudiantes universitarios del centro de Bogotá. Previo consentimiento informado, se procedió a la medición de la composición corporal, a través de la toma de: pliegue tricipital y supraescapular mediante adipometro, perímetro de cintura, índice de Masa Corporal, Masa Magra, Masa Grasa y porcentaje de grasa entre otras. También se realizaron tomas de muestras de sangre para determinar glucemia, colesterol total, triglicéridos y lipoproteínas, cuya relación permite el cálculo del índice aterogénico. De una muestra final de 76 estudiantes, el 15,5% presenta sobrepeso; el 76,5 % está dentro de rangos considerados normales; y el 8,0% presenta bajo peso. En lo referente a los datos por sexo, se encontró que un 5,5 % de hombres y un 19,0% de las mujeres presentaban sobrepeso y un 5,5% de los hombres y un 8,6 % de las mujeres presentaban bajo peso, en ningún caso hubo personas obesas. El perímetro de cintura varió entre 68 y 97 cm en hombres y entre 61 y 92 cm en mujeres, finalmente el porcentaje de grasa estuvo entre 27,6 a 30,7 en hombres y entre 11,0 a 36,9 en mujeres. Teniendo en cuenta los resultados obtenidos, es importante promover en nuestra población una cultura de hábitos saludables, caracterizada por una alimentación saludable y una mayor actividad física; también se recomienda, especialmente durante los primeros años de vida, ya que es en esta etapa donde se adquieren o instauran gran parte de los mismos y que en muchos casos permanecerán toda la vida.
Obesity and its complications are one of the major pandemics at the global level, especially type 2 diabetes that is associated with insulin resistance. The purpose of this paper is to describe the relationship between obesity and other cardiovascular risk factors of university students in downtown Bogota. After obtaining an informed consent, we proceeded to the measurement of the following body parts: triceps skinfold and suprascapular through adipometer, waist circumference, body mass index, lean mass, fat mass and fat glucose, total percentage among others. Blood samples were also taken to determine blood cholesterol, triglycerides, and lipoproteins, whose relationship allows the calculation of the atherogenic index. From a final sample of 76 students, 15.5 % was overweight; 76.5 % was considered within normal ranges; and the 8.0 % was underweight. In regard to the data by sex, it was found that a 5.5 % of men and 19.0 % of women were overweight and 5.5 % of men and 8.6 % of the women had low weight, there were no obese people in any case. The waist perimeter varied between 68 and 97 cm in men and between 61 and 92 cm in women, finally the fat percentage was between 27.6 and 30.7 in men and from 11.0 to 36.9 in women. Taking into account the results obtained, it is important to promote in our population a culture of healthy habits, characterized by a healthy diet and increased physical activity; it is also recommended, especially during the first years of life, as it is in this stage where the majority of these habits are acquired and will last for life.
