YouTube® as a source of information for Spanish-speaking patients with rheumatoid arthritis.

INTRODUCTION: Social media (SoMe) has reshaped access to health information, which may benefit patients with rheumatoid arthritis (RA), although an evaluation of the characteristics of contents for Spanish-speaking patients is lacking. We aimed to assess patient engagement, reliability, comprehensiveness, and quality of data uploaded to YouTube® for Spanish-speaking patients. METHODS: We evaluated the videos uploaded to YouTube® in Spanish about RA. Information about video length, engagement (i.e., views, likes, popularity index), time online, and the source was retrieved; we appraised reliability (DISCERN), comprehensiveness (content score), and quality (Global Quality Score) using standardized scores. RESULTS: We included 200 videos in the study and classified 67% of the videos as useful. These videos had a higher number of views (19,491 [10,132-61,162] vs. 11,208 [8183-20,538]), a longer time online (1156 [719-2254] vs. 832 [487-1708] days), and a shorter duration (6.3 [3.4-15.8] vs. 11.8 [7.4-20.3] min). Engagement parameters were similar between useful and misleading videos. Useful videos had higher reliability, comprehensiveness, and quality scores. Useful videos were mainly uploaded by independent users and government/news agencies; academic organizations offered only 15% of useful videos. CONCLUSIONS: Most of the information in YouTube® for Spanish-speaking patients with RA is useful; however, patient engagement is similar between useful and misleading content. More substantial involvement of academia in developing high-quality educational multimedia is warranted.

Introducción: Las redes sociales (ReSo) han redefinido el acceso a la información en salud, beneficiando a los pacientes con artritis reumatoide (AR). No se cuenta con una evaluación de las características de su contenido para pacientes hispanohablantes. Nuestro objetivo fue evaluar los parámetros de interacción, la confiabilidad, la exhaustividad y la calidad de la información disponible en YouTube® para pacientes hispanohablantes con AR. Métodos: Evaluamos los videos en español sobre AR disponibles en YouTube®. Se extrajo información sobre la duración del video, los parámetros de interacción (por ejemplo, vistas, likes, índice de popularidad), el tiempo en línea y la fuente generadora. Estimamos la confiabilidad (DISCERN), la exhaustividad (puntaje de contenido) y la calidad (Global Quality Score) utilizando puntajes estandarizados. Resultados: Incluimos 200 videos en el estudio y clasificamos a 67% como videos útiles. Estos videos tuvieron un mayor número de vistas (19.491 [10.132-61.162] vs. 11.208 [8.183-20.538]), un mayor tiempo en línea (1.156 [719-2.254] vs. 832 [487-1.708] días) y una menor duración (6,3 [3,4-15,8] vs. 11,8 [7,4-20,3] min). Los parámetros de interacción fueron similares entre los videos útiles y los no útiles. Los videos útiles presentaron puntajes mayores de confiabilidad, exhaustividad y calidad; en su mayoría fueron generados por usuarios independientes y por organizaciones gubernamentales/agencias de noticias. Las organizaciones académicas generaron únicamente 15% de los videos útiles. Conclusiones: La mayoría de la información en YouTube® para pacientes hispanohablantes con AR es útil. Sin embargo, los parámetros de interacción son similares entre los videos útiles y los no útiles. Se requiere una mayor participación de las organizaciones académicas en el desarrollo de multimedia educativo de alta calidad.(AU)

Prolongation of the QTc Interval at Admission is Associated with Increased Mortality in Patients with SARS-COV-2 during Hospitalization. / O Prolongamento do Intervalo QTc na Admissão está Associado ao Aumento da Mortalidade em Pacientes com SARS-COV-2 durante a Hospitalização.

BACKGROUND: Cardiovascular involvement associated with SARS-COV-2 infection is related to unfavorable outcomes during hospitalization. Therefore, the measurement at the admission of the QTc interval on the 12-lead electrocardiogram may be a prognostic marker. OBJECTIVE: To identify the relationship between QTc prolongation at admission during hospitalization and mortality from SARS-COV-2. METHOD: Observational study based on a retrospective cohort of patients with confirmed SARS-COV-2 infection from San Ignacio University Hospital, Bogotá (Colombia), between March 19, 2020, and July 31, 2021. Mortality was compared in patients with prolonged and normal QTc at admission after controlling by clinical variables and comorbidities using bivariate and multivariate logistic regression models. A p-value <0.05 was considered statistically significant. RESULTS: 1296 patients were analyzed, and 127 (9.8%) had prolonged QTc. Mortality was higher in patients with prolonged QTc (39.4% vs 25.3%, p=0.001), as was hospital stay (median 11vs.8 days; p=0.002). In the multivariate analysis, mortality was associated with prolonged QTc (OR 1.61, 95% CI: 1.02; 2.54, p=0.038), age (OR 1.03, 95% CI 1.02; 1.05, p<0.001), male sex (OR 2.15, 95% CI 1.60; 2.90, p <0.001), kidney disease (OR 1.32, 95% CI 1.05; 1.66, p =0.018) and Charlson comorbidity index > 3 (OR 1.49, 95% CI 1.03; 2.17, p=0.035). CONCLUSIONS: Hospital mortality due to SARS-COV-2 is associated with prolonging the QTc interval at the time of admission, even after adjusting for age, sex, comorbidities, and basal severity of infection. Additional research is needed to establish whether these findings are related to cardiac involvement by the virus, hypoxia, and systemic inflammation.

FUNDAMENTO: O envolvimento cardiovascular associado à infecção por SARS-COV-2 está relacionado a desfechos desfavoráveis durante a internação. Portanto, a medida na admissão do intervalo QTc no eletrocardiograma de 12 derivações pode ser um marcador prognóstico. OBJETIVO: Identificar a relação entre o prolongamento do QTc na admissão durante a hospitalização e a mortalidade por SARS-COV-2. MÉTODO: Estudo observacional baseado em uma coorte retrospectiva de pacientes com infecção confirmada por SARS-COV-2 do Hospital Universitário San Ignacio, Bogotá (Colômbia), entre 19 de março de 2020 e 31 de julho de 2021. A mortalidade foi comparada em pacientes com QTc prolongado e normal na admissão e controle das variáveis clínicas e comorbidades por meio de modelos de regressão logística bivariada e multivariada. Um valor de p <0,05 foi considerado estatisticamente significativo. RESULTADOS: Foram analisados 1.296 pacientes e 127 (9,8%) apresentaram QTc prolongado. A mortalidade foi maior em pacientes com QTc prolongado (39,4% vs. 25,3%, p=0,001), assim como o tempo de internação (mediana 11 vs. 8 dias; p=0,002). Na análise multivariada, a mortalidade foi associada a QTc prolongado (OR 1,61, IC 95%: 1,02; 2,54, p=0,038), idade (OR 1,03, IC 95% 1,02; 1,05, p<0,001), sexo masculino (OR 2,15, IC 95% 1,60; 2,90, p<0,001), doença renal (OR 1,32, IC 95% 1,05; 1,66, p=0,018) e índice de comorbidade de Charlson > 3 (OR 1,49, IC 95% 1,03; 2,17, p=0,035). CONCLUSÕES: A mortalidade hospitalar por SARS-COV-2 está associada ao prolongamento do intervalo QTc no momento da admissão, mesmo após ajuste para idade, sexo, comorbidades e gravidade basal da infecção. Pesquisas adicionais são necessárias para estabelecer se esses achados estão relacionados ao envolvimento cardíaco pelo vírus, hipóxia e inflamação sistêmica.

Randomized double-blind clinical study in patients with COVID-19 to evaluate the safety and efficacy of a phytomedicine (P2Et).

Background: It has been proposed that polyphenols can be used in the development of new therapies against COVID-19, given their ability to interfere with the adsorption and entrance processes of the virus, thus disrupting viral replication. Seeds from Caesalpinia spinosa, have been traditionally used for the treatment of inflammatory pathologies and respiratory diseases. Our team has obtained an extract called P2Et, rich in polyphenols derived from gallic acid with significant antioxidant activity, and the ability to induce complete autophagy in tumor cells and reduce the systemic inflammatory response in animal models. Methods: In this work, a phase II multicenter randomized double-blind clinical trial on COVID-19 patients was designed to evaluate the impact of the P2Et treatment on the clinical outcome and the immunological parameters related to the evolution of the disease. The Trial was registered with the number No. NCT04410510*. A complementary study in an animal model of lung fibrosis was carried out to evaluate in situ lung changes after P2Et in vivo administration. The ability of P2Et to inhibit the viral load of murine and human coronaviruses in cellular models was also evaluated. Results: Patients treated with P2Et were discharged on average after 7.4 days of admission vs. 9.6 days in the placebo group. Although a decrease in proinflammatory cytokines such as G-CSF, IL-15, IL-12, IL-6, IP10, MCP-1, MCP-2 and IL-18 was observed in both groups, P2Et decreased to a greater extent G-CSF, IL-6 and IL-18 among others, which are related to lower recovery of patients in the long term. The frequency of T lymphocytes (LT) CD3+, LT double negative (CD3+CD4-CD8-), NK cells increased in the P2Et group where the population of eosinophils was also significantly reduced. In the murine bleomycin model, P2Et also reduced lung inflammation and fibrosis. P2Et was able to reduce the viral replication of murine and human coronaviruses in vitro, showing its dual antiviral and anti-inflammatory role, key in disease control. Conclusions: Taken together these results suggest that P2Et could be consider as a good co-adjuvant in the treatment of COVID-19.

Cambio en la mortalidad intrahospitalaria durante el primer pico por SARS- COV-2 en Bogotá, Colombia / Change of in-hospital mortality during the first SARS-COV-2 surge in Bogotá, Colombia

Resumen Introducción: La mortalidad por SARS-COV-2 ha disminuido en diferentes países, pero no se ha evaluado si es igual en Colombia, o si se relaciona con las carac terísticas de los pacientes y tratamientos utilizados. Objetivo: Comparar la mortalidad por SARS-COV-2, en dos periodos de tiempo controlando por factores de riesgo asociados con mortalidad. Metodología: Estudio observacional, basado en una cohorte retrospectiva de pacientes con SARS-COV-2 atendidos en el Hospital Universitario San Ignacio, Bogotá (Colombia), desde el 19 de marzo al 12 de noviembre, 2020. Se comparó la tasa de mortalidad intrahospitalaria de los pacientes egresados antes y después del 21 de agosto de 2020 (primer pico de mortalidad en Colombia) y se analizó el impacto del momento de atención controlando por comorbilidades, severidad al ingreso y tratamiento recibido, usando un modelo de regresión logística. Resultados: 1399 pacientes (944 antes y 455 después del primer pico de mortalidad) fueron analizados. La tasa de mortalidad intrahospitalaria global fue similar en ambos periodos (17.6% vs 16.3%, p=0.539). En el análisis multivariado se encontró que la atención en el segundo periodo de tiempo se asoció a menor mortalidad (OR 0.66 IC95% 0.47; 0.93, p=0.018), a diferencia del aumento de la misma asociado a la edad (OR 1.06 IC95% 1.05; 1.07, p<0.001), sexo masculino (OR 1.84 IC95% 1.33; 2.54 p<0.001), cirrosis (OR 1.89 IC95% 1.24; 2.88, p=0.003), enfermedad renal (OR 1.36 IC95% 1.00; 1.83, p=0.043) y el uso de dexametasona (OR 1.53 IC95% 1.03; 2.28, p=0.031). Conclusiones: La tasa de mortalidad intrahospitalaria se redujo después del 21 de agosto durante la primera ola de la pandemia en Bogotá, posiblemente asociado a la mejoría en la capacidad de respuesta del sistema de salud en ese momento, o a un menor inoculo viral de los pacientes infectados. Estos hallazgos pueden cambiar con la saturación del sistema de salud.

Abstract Introduction: Mortality secondary to SARS-COV 2 has decreases around the world, however this has not been evaluated in Colombia neither has the correlation between patient characteristics or treatments. Objective: To compare the mortality due to SARS-COV-2, in two periods of time, controlling risk factors associated with mortality. Methodology: Observational retrospective cohort study of patients with SARS- COV-2 treated at the San Ignacio University Hospital in Bogotá (Colombia), from March 19 to November 12, 2020. The in-hospital mortality rate of patients discharged before and after August 21, 2020 (surge mortality in Colombia) was com pared. The impact of the moment of attention was analyzed controlled by comorbidities, severity at admission and treatment received using a bivariate and multivariate logistic regression model. Results: 1399 patients (944 before and 455 after August 21) were analyzed. The overall in-hospital mortality rate was similar at both times (17.6%vs16.3percentage, p=0.539). In the multivariate analysis, it was found that the moment of attention was associated with lower mortality (OR 0.66 95% CI0.47;0.93,p=0.018), in contrast to its increase associated with age (OR 1.06 95% CI 1.05;1.07,p=<0.001), male sex (OR 1.84 95%CI 1.33;2.54,p=<0.001), cirrhosis (OR1.89 95%CI 1.24;2.88, p=0.003), kidney disease (OR 1.36 95% CI1.00;1.83,p=0.043) and the use of dexamethasone (OR1.53 95%CI 1.03;2.28,p=0.031). Conclusions: The in-hospital mortality rate fell after August 21 during the first wave of the pandemic in Bogotá-Colombia, possibly associated with an improvement in response capacity, or a lower viral inoculum of infected patients. These findings may change with the saturation of the health system

Pediatric Index of Mortality 2 e 3 são preditores de mortalidade iguais? Estudo de concordância com base em unidade de terapia intensiva / Are the Pediatric Index of Mortality 2 and 3 equal predictors of mortality? An intensive care unit-based concordance study

RESUMO Objetivo: Determinar a concordância da classificação do risco de mortalidade por meio do uso dos escores Pediatric Index of Mortality (PIM) 2 e 3. Métodos: Avaliação de uma coorte retrospectiva pela análise dos pacientes admitidos à unidade de terapia intensiva pediátrica entre abril de 2016 e dezembro de 2018. Calculamos o risco de mortalidade por meio do PIM 2 e do 3. Realizaram-se análises para determinar a concordância entre a classificação de risco obtida com ambas as escalas pela utilização do cálculo do Kappa não ponderado e linearmente ponderado. Resultados: Incluímos 722 pacientes, sendo que 66,6% destes tinham uma condição crônica. A mortalidade global foi de 3,7%. O coeficiente Kappa de concordância para classificação dos pacientes, segundo o risco com o PIM 2 e o 3, foi moderado: 0,48 (IC95% 0,43 - 0,53). Após ponderação linear, a concordância foi substancial: 0,64 (IC95% 0,59 - 0,69). Para pacientes de cirurgia cardíaca, a concordância para a classificação de risco foi regular: 0,30 (IC95% 0,21 - 0,39); após ponderação linear, a concordância foi apenas moderada: 0,49 (IC95% 0,39 - 0,59). O PIM 3 acusou um risco mais baixo do que o PIM 2 em 44,8% dos pacientes desse subgrupo. Conclusão: Nosso estudo comprova que o PIM 2 e o 3 não são clinicamente equivalentes e não devem ser usadas de forma intercambiável para avaliação da qualidade em diferentes unidades de terapia intensiva. Devem ser conduzidos estudos de validação antes que se utilizem os PIM 2 e 3 em situações específicas.

ABSTRACT Objective: To determine the concordance of mortality risk classification through the use of the Pediatric Index of Mortality (PIM) 2 and 3. Methods: Through a retrospective cohort, we evaluated patients admitted to the pediatric intensive care unit between April 2016 and December 2018. We calculated the mortality risk with the PIM 2 and 3. Analyses were carried out to determine the concordance between the risk classification obtained with both scales using unweighted and linearly weighted kappa. Results: A total of 722 subjects were included, and 66.6% had a chronic condition. The overall mortality was 3.7%. The global kappa concordance coefficient for classifying patients according to risk with the PIM 2 and 3 was moderate at 0.48 (95%CI 0.43 - 0.53). After linear weighting, concordance was substantial at 0.64 (95%CI 0.59 - 0.69). For cardiac surgery patients, concordance for risk classification was fair at 0.30 (95%CI 0.21 - 0.39), and after linear weighting, concordance was only moderate at 0.49 (95%CI 0.39 - 0.59). The PIM 3 assigned a lower risk than the PIM 2 in 44.8% of patients in this subgroup. Conclusion: Our study proves that the PIM 2 and 3 are not clinically equivalent and should not be used interchangeably for quality evaluation across pediatric intensive care units. Validation studies must be performed before using the PIM 2 or PIM 3 in specific settings.

Therapeutic impact of statins on the lipid profile and cardiovascular risk of patients with rheumatoid arthritis: Systematic literature review and meta-analysis / Impacto terapéutico de las estatinas en el perfil lipidico y riesgo cardiovascular en pacientes con artritis reumatoide: Revisión sistemática de la literatura y metaanálisis

ABSTRACT Context: Patients with rheumatoid arthritis have a higher cardiovascular risk due to the prevalence of cardiovascular risk factors and metabolic alterations derived from the inflammatory activity and the treatment of their disease. A systematic evaluation of the effect of statins on lipid fractions and cardiovascular outcomes has not been carried out specifically in patients with rheumatoid arthritis. Methods: A literature search was conducted in Medline (PubMed), Embase, Lilacs, SciELO, and Cochrane. Randomized and non-randomized clinical trials were selected that evaluated the impact of statins on mortality, cardiovascular events, lipid fractions and disease activity in patients with rheumatoid arthritis. A paired evaluation of risk of bias was carried out, along with a meta-analysis using RevMan 5.3®. Results: A total of 5 studies and 383 patients were included in the analysis. The use of statins among patients with rheumatoid arthritis significantly reduced total cholesterol levels: -46.16mg/dL (95% CI: [-53.89, -38.46]; I 2: 86%), LDLc: -18.13mg/dL (95% CI: [-21.8, -14.4], I 2: 97%) and TG of -34.95 mg/dL (95% CI: [-44.3, -25.6], I 2: 0%), without significant changes in HDLc. It also reduced the activity of the disease (DAS28) by 0.73 (95% CI: [-0.94, -0.53], I 2: 96%). No study was found that reported mortality or cardiovascular outcomes. Conclusion: The lipid-lowering effect of statins in patients with rheumatoid arthritis is consistent with that found in other populations. There is a slight impact in reducing the activity of the disease, but reducing the risk of cardiovascular events in this specific population has not been studied.

RESUMEN Contexto: Los pacientes con artritis reumatoide tienen un riesgo cardiovascular elevado por la alta prevalencia de factores de riesgo cardiovascular y de alteraciones metabólicas derivadas de la actividad inflamatoria y del tratamiento de su enfermedad. No se ha realizado una evaluación sistemática del efecto de las estatinas en las fracciones lipídicas y desenlaces cardiovasculares específicamente en pacientes con artritis reumatoide. Métodos: Se realizó una búsqueda de la literatura en Medline (PubMed), Embase, Lilacs, SciELO y Cochrane. Se seleccionaron experimentos clínicos aleatorizados y no aleatorizados (estudios de cohortes) que evaluaran el impacto de las estatinas en mortalidad, eventos cardiovasculares, fracciones lipídicas y actividad de la enfermedad en pacientes con artritis reumatoide. Se realizó la selección, evaluación del riesgo de sesgos de forma pareada y un metaanálisis con RevMan 5.3®. Resultados: Un total de 5 estudios y 383 pacientes fueron incluidos en el análisis. El uso de estatinas en pacientes con artritis reumatoide reduce significativamente los niveles de colesterol total: -46,16 mg/dL (IC 95%: [-53,89; -38,46]; I 2: 86%), LDLc: -18,13 mg/dL (IC 95%: [-21,8; -14,4]; I 2: 97%) y triglicéridos de -34,95 mg/dL (IC 95%: [-44,3; -25,6]; I 2: 0%), sin cambios significativos del HDLc. Además, reduce la actividad de la enfermedad (DAS28) en 0,73 (IC 95%: [-0,94; -0,53]; I 2: 96%). No se encontró ningún estudio que reportara mortalidad ni desenlaces cardiovasculares. Conclusión: El efecto hipolipidemiante de las estatinas en pacientes con artritis reumatoide es consistente con lo encontrado en otras poblaciones. Existe un discreto impacto en la reducción de actividad de la enfermedad; sin embargo, la reducción del riesgo de eventos cardiovasculares en esta población específica no ha sido estudiada.

Therapeutic Impact of Statins on the Lipid Profile and Cardiovascular Risk in Patients With Systemic Lupus Erythematosus: Systematic Review of the Literature and a Meta-analysis. / Impacto terapéutico de las estatinas en el perfil lipídico y el riesgo cardiovascular en pacientes con lupus eritematoso sistémico: revisión sistemática de la literatura y metaanálisis.

BACKGROUND: There is strong evidence of a rise in cardiovascular risk in patients suffering from autoimmune diseases, especially in those with Sistemic Lupus Erythematosus. Until now, there are a few trials that assess the potencial benefit of statins on the incidence of cardiovascular events and on lipid profile of patients with SLE. This evidence has not been synthesized and assessed altogether. METHODS: We performed a search in databases of literature published until August of 2016 (Embase, MEDLINE, Cochrane Library, SciELO, Clinical Evidence, DynaMed, Cochrane Central Register of Controlled Trials, LILACS), identifying controlled clinical trials that could estimate the impact of statins on mortality, cardiovascular events, C-reactive protein and lipid profile in patients with Systemic Lupus Erythematosus. The quality of the information available was assessed with a meta-analysis, using a random effects model, employing the RevMan 5.3 software. RESULTS: 6 trials and 412 patients were included in the analysis. The use of statins in patients with SLE was found to significantly reduce the levels of serum total cholesterol (mean difference [MD] -31,4 mg/dL; CI 95% -43,0; -19,9), and serum low density cholesterol (MD -31,4 mg/dL; IC 95% -43,0; -19,9), but had no impact on levels of serum triglycerides (MD 4 mg/dL; IC 95% 2,49; 6,21) and C-reactive protein (MD -0,78; IC 95% -1,43; -0,13). No evidence was found about the impact on the risk of mortality or cardiovascular events. CONCLUSION: Statins have a significant effect on the levels of serum total cholesterol, LDL cholesterol and C-reactive protein, however, more randomized controlled trials with long-term follow-up are necessary to assess the impact on mortality and cardiovascular risk.

Evaluación automática de la adherencia a las recomendaciones de manejo en falla cardiaca a partir de las historias clínicas electrónicas: herramienta EXEMED / Automatic evaluation of the adherence to recommendations for managing heart failure from the electronic health records: The EXEMED tool

Resumen Objetivo: La implementación de las guías de práctica clínica está limitada por la falta de herramientas que faciliten los procesos de auditoría y retroalimentación a los profesionales de salud. Este estudio evalúa la herramienta automatizada (EXEMED), diseñada para valorar la adherencia a las guías de práctica clínica a partir de la información consignada en las historias clínicas electrónicas. Métodos: En un grupo de 35 pacientes hospitalizados entre enero y marzo de 2016 se evaluó la adherencia a cinco recomendaciones contenidas en las guías de práctica clínica de falla cardiaca del Hospital Universitario San Ignacio. Se utilizó la herramienta automatizada EXEMED y se evaluó la validez de la misma comparando los resultados con la valoración realizada por una junta médica independiente. Se determinó concordancia entre los dos métodos usando el coeficiente kappa. Resultados: La adherencia a las diferentes recomendaciones osciló entre 0% para la determinación del perímetro abdominal al ingreso, hasta 97% para el uso de betabloqueadores al egreso. La proporción de acuerdo entre los dos métodos de evaluación estuvo por encima del 90% para todas las recomendaciones. El kappa para las diferentes recomendaciones fue de 0,78 (IC 95% 0,62-0,95) y 0,64 (0,48-0,80). El tiempo de evaluación se redujo de veinte a dos minutos por paciente con el uso de la herramienta EXEMED. Conclusiones: EXEMED es una herramienta válida y eficiente en la evaluación de la adherencia a las guías de práctica clínica. Se requieren nuevos estudios para evaluar el impacto de su uso asociado a retroalimentación a los clínicos, en la evolución a largo plazo de los pacientes con falla cardiaca.

Abstract Objective: The implementation of clinical practice guidelines is limited due to the lack of tools to carry out audits and provide feedback to the health professionals. In this study, an evaluation is performed using the automated (EXEMED) tool in order to assess the adherence to clinical practice guidelines from the information entered in the electronic health records. Methods: The adherence to 5 recommendations contained in the heart failure clinical practice guidelines was evaluated in a group of 35 patients admitted to the Hospital Universitario San Ignacio between January 2016 and March 2016. The automated EXEMED tool was used to assess this, by comparing the results obtained with the evaluation carried out by an independent medical committee. The kappa coefficient was used to determine the agreement between the two methods. Results: The adherence to the different recommendations varied between 0%, for the determination of the abdominal circumference, up to 97%, for the use of beta-blockers at discharge. Percentage agreement between the two evaluation methods was above 90% for all the recommendations. The kappa for the different recommendations was 0.78 (95% CI; 0.62-0.95) and 0.64 (0.48-0.80). The evaluation time was reduced from 20 minutes to 2 minutes with the use of the EXEMED tool. Conclusions: EXEMED is a valid and effective tool in the evaluation of adherence to clinical practice guidelines. Further studies are required to assess the impact of its used associated with feedback to the clinicians, in the long-term outcomes of patients with heart failure.

La prescripción de inhibidores de la dipeptidil peptidasa-4 fue 7 % y la frecuencia de prescripción de agonista del receptor del péptido similar al glucagón tipo 1 (AR GLP-1) fue de 2 %. El medicamento con mayor frecuencia de prescripción como monoterapia fueron las biguanidas (22 %). La combinación más frecuente fue biguanida y las sulfonilureas (21 %), seguida de biguanida e insulina (10 %), y otras combinaciones. El 27 % pacientes con DM2 no recibió ningún tratamiento farmacológico para la diabetes. Con respecto a los medicamentos para comorbilidades, el 52 % de los pacientes utiliza al menos un tipo de antihipertensivo, el 39 % usa al menos un tipo de hipolipemiante y el 35 % utiliza ácido acetilsalicílico. Conclusiones: Las biguanidas fueron el medicamento con mayor frecuencia de prescripción, seguido de las sulfonilureas. Uno de cada cuatro pacientes no tenía registro de prescripción de medicamentos. El uso de ácido acetilsalicílico como prevención del riesgo cardiovascular fue menor al esperado.

Abstract Objetive: to describe the patterns of medicine prescriptions for diabetes mellitus type 2 (dm2) and the comorbidity of patients in five health care institutions in Colombia. Methodology: descriptive cross-sectional study carried out checking the medical records of 5098 patients with dm2 treated at the outpatient service centers in five Colombian cities between January 1 and December 31 of 2014. Each patient with dm2 had a record of at least two outpatient appointments registered during the time of this study. The information was collected through electronic surveys. National and international guides on diabetes treatment were used to categorize the medications. The spss® 21 software was used to analyze the data. Results: the most frequently prescribed medications were biguanides (59%) and sulfonylureas (28%). The prescription of inhibitors for Dipeptidyl peptidase-4 was 7% and the frequency of prescription of glucagon-like peptide-1 receptor agonists (ar glp-1) was 2%. The medication with the highest frequency of prescription as monotherapy were biguanides (22%). The most frequent combination was biguanide and sulfonylureas (21%). The second most frequent combination was biguanide with insulin (10%), and other combinations. 27% of patients with dm2 did not receive any pharmacological treatment for diabetes. Regarding the medicines for comorbidity, 52% of patients use at least one type of antihypertensive drug, 39% use at least one type of hypolipidemic drug and 35% uses acetylsalicylic acid. Conclusions: biguanides were the most frequently prescribed medication, sulfonylureas came after. One in four patients did not have a record of medicine prescription. The prescription of acetylsalicylic acid to prevent cardiovascular risk was lower than expected.

Muerte cerebral secundaria a intoxicación por metanol / Brain death secondary to methanol poisoning

Las intoxicaciones por alcohol metílico son raras, pueden ser secundarias a intentos suicidas, accidentes e incluso a envenenamientos endémicos, tienen consecuencias severas que incluyen la muerte, secundarias a productos de la degradación del alcohol metílico por la alcohol deshidrogenasa, a continuación, presentamos un caso de intoxicación por alcohol metílico que como secuelas presentó alteraciones neurológicas y muerte. (Acta Med Colomb 2012; 37: 211-214).

Methyl alcohol poisoning is rare and may be secondary to suicide attempts, accidents and is also caused by endemic poisonings. It has severe consequences including death secondary to degradation products of methyl alcohol by alcohol dehydrogenase. We present a case of methyl alcohol poisoning that presented neurological alterations and death. (Acta Med Colomb 2012; 37: 211-214).
