Minigammacámara portátil para el diagnóstico de muerte encefálica / Portable gamma-camera for the diagnosis of brain death diagnosis

Objetivo: Evaluar la factibilidad del empleo de la minigammacámara portátil Sentinella(R), para el diagnóstico de muerte encefálica (ME). Diseño: Estudio observacional, prospectivo, de factibilidad. Ámbito: Unidad de cuidados intensivos de un hospital de tercer nivel. Pacientes: Desde enero a diciembre de 2017 se registraron de forma consecutiva los pacientes mayores de edad que tras su ingreso en unidad de cuidados intensivos fueron diagnosticados de ME según criterios clínicos. Intervenciones: El procedimiento se realizó a la cabecera del paciente tras la administración intravenosa de tecnecio 99 metaestable-hexametil-propilen-amino-oxima. La ausencia de perfusión a nivel de hemisferios cerebrales y fosa posterior se describía como patrón compatible con ME. Se correlacionó el diagnóstico con doppler transcraneal y/o electroencefalograma. Resultados: Cincuenta y seis pacientes presentaron exploración física compatible con ME. Un 66,1% fueron hombres con una mediana de edad de 60 (RIQ: 51-72) años. La causa más frecuente que precipitó la ME fue el ictus hemorrágico en el 48,2% (27) seguido por traumatismo craneoencefálico grave en el 30,4% (17), ictus isquémico en el 10,7% (6) y encefalopatía anóxica tras parada cardiorrespiratoria en el 7,1% (4). En todos los casos se realizó el diagnóstico clínico de ME y posteriormente una gammagrafía portátil que confirmó dicho diagnóstico en el 100% de los pacientes. Se contrastó el resultado con doppler transcraneal en 46 de ellos que confirmaba la presencia de reverberación diastólica y/o picos sistólicos. En 10 casos se registró el electroencefalograma, con aparición de silencio eléctrico, debido a la ausencia de ventana acústica en el doppler transcraneal. Conclusiones: El uso de minigammacámara portátil puede resultar una herramienta útil y factible para el diagnóstico de ME

Objective: To evaluate the feasibility of using the Sentinella(R) portable gamma-camera for the diagnosis of brain death (BD). Design: A prospective, observational feasibility study was carried out. Setting: Intensive Care Unit of a third level hospital. Patients: Consecutive recording was made of the adults diagnosed with brain death based on clinical criteria following admission to the Intensive Care Unit in the period from January to December 2017. Interventions: The procedure was performed at the patient bedside with the intravenous administration of technetium 99 metastable hexamethylpropylene amine oxime. The absence of perfusion in the cerebral hemispheres and brainstem was described as a pattern consistent with BD. The diagnosis was correlated to the transcranial Doppler and / or electroencephalographic findings. Results: A total of 66.1% of the patients were men with an average age of 60 years [IQR: 51-72]. The most frequent causes resulting in BD were hemorrhagic stroke (48.2%, n=27), followed by traumatic brain injury (30.4%, n=17), ischemic stroke (10.7%, n=6) and post-cardiac arrest anoxic encephalopathy (7.1%, n=4). A clinical diagnosis of BD was made in all cases, and the portable gamma-camera confirmed the diagnosis in 100% of the patients with a pattern characterized by the absence of brain perfusion. In addition, the results were compared with the transcranial Doppler findings in 46 patients, confirming the presence of diastolic reverberation and / or systolic peaks. The electroencephalographic tracing was obtained in 10 cases, with the appearance of electrical silence, due to the absence of an acoustic window in the transcranial Doppler study. Conclusions: A portable gamma-camera could be a useful and feasible tool for the diagnosis of BD

Marcadores para la detección precoz de las alteraciones del metabolismo hidrocarbonado tras un infarto agudo de miocardio / Markers for early detection of alterations in carbohydrate metabolism after acute myocardial infarction

OBJETIVO: Las alteraciones del metabolismo hidrocarbonado no conocidas son frecuentes en los pacientes con infarto agudo de miocardio, sin que exista un consenso en que pacientes estudiar para su identificación precoz. Nuestro objetivo es evaluar qué variables al ingreso se asocian al diagnóstico posterior de una alteración de dicho metabolismo. DISEÑO: Estudio de cohortes prospectivo. Ámbito: Servicio de Medicina Intensiva del Hospital Universitario Virgen de la Arrixaca (Murcia), España. PACIENTES: Un total de 138 pacientes ingresados en la UCI con infarto agudo de miocardio sin diabetes conocida ni de novo fueron, transcurrido un año, estudiados mediante un test de sobrecarga oral de glucosa. Variables principales: Se recogieron variables clínicas y parámetros analíticos al ingreso y trascurrido un año. Además, al año, se realizó una sobrecarga oral de glucosa y se estudió la capacidad diagnóstica para la diabetes de las variables al ingreso mediante las curvas ROC y análisis multivariable. RESULTADOS: Entre 138 pacientes estudiados, 112 (72,5%) presentaron una alteración del metabolismo hidrocarbonado, incluido un 16,7% de diabetes. La HbA1c se asoció independientemente con el diagnóstico de diabetes (RR: 7,28, IC 95%: 1,65-32,05, p = 0,009) y presentó la mejor área bajo la curva ROC para diabetes (0,81, IC 95%: 0,69-0,92, p < 0,001). CONCLUSIONES: En los pacientes con infarto agudo de miocardio, la HbA1c ayuda a identificar aquellos con alteración del metabolismo hidrocarbonado transcurrido un año. De esta forma, su determinación en este grupo de pacientes puede ser utilizada para identificar a aquellos que precisan un estudio mas detallado para establecer un diagnóstico precoz

OBJECTIVES: Undiagnosed abnormal glucose metabolism is often seen in patients admitted with acute myocardial infarction, although there is no consensus on which patients should be studied with a view to establishing an early diagnosis. The present study examines the potential of certain variables obtained upon admission to diagnose abnormal glucose metabolism. DESIGN: A prospective cohort study was carried out. SETTING: The Intensive Care Unit of Arrixaca University Hospital (Murcia), Spain. PATIENTS: A total of 138 patients admitted to the Intensive Care Unit with acute myocardial infarction and without known or de novo diabetes mellitus. After one year, oral glucose tolerance testing was performed. Main outcomes: Clinical and laboratory test parameters were recorded upon admission and one year after discharge. Additionally, after one year, oral glucose tolerance tests were made, and a study was made of the capacity of the variables obtained at admission to diagnose diabetes, based on the ROC curves and multivariate analysis. RESULTS: Of the 138 patients, 112 (72.5%) had glucose metabolic alteration, including 16.7% with diabetes. HbA1c was independently associated with a diagnosis of diabetes (RR: 7.28, 95% CI 1.65 to 32.05, P = .009), and showed the largest area under the ROC curve for diabetes (0.81, 95% CI 0.69 to 0.92, P = .001). CONCLUSIONS: In patients with acute myocardial infarction, HbA1c helps identify those individuals with abnormal glucose metabolism after one year. Thus, its determination in this group of patients could be used to identify those subjects requiring a more exhaustive study in order to establish an early diagnosis

Ajuste del tratamiento farmacológico a las guías de práctica clínica en pacientes octogenarios con infarto agudo de miocardio / Drug treatment adjustment to the clinical guidelines in octagenarians with acute myocardial infarction

Objetivo: Determinar si existe una asociación lineal de la edad y la administración de aspirina ,betabloque antes, inhibidores de la enzima convertidora de la angiotensina y estatinas, en qué medida los pacientes de edad avanzada reciben estos tratamientos y si la edad se asocia de forma independiente a estos tratamientos. Diseño: Estudio de cohortes prospectivo. Ámbito: Unidades Coronarias de 2 hospitales de la Región de Murcia Pacientes: Pacientes consecutivos ingresados con el diagnóstico de infarto agudo de miocardio entre enero de 1998 y enero de 2008.Intervenciones: Ninguna. Variables principales: Las relacionadas con la administración de aspirina, betabloqueantes, inhibidores de la enzima convertidora de la angiotensina y estatinas durante la estancia en la Unidad Coronaria. Resultados: Respecto al resto de pacientes, los octogenarios recibieron en similar proporción inhibidores de la enzima convertidora de la angiotensina (70,8 vs 69,3%, p=0,41) y con menor frecuencia aspirina (90,4 vs 94,6%, p<0,001), betabloqueantes (44,4 vs 69,4%, p<0,001) y estatinas(47,6 vs 64,7%, p<0,001). Solo pudo demostrarse una disminución brusca y significativa en la administración de estatinas a partir de los 80 años. La edad se asoció independientemente con la administración de betabloqueantes (OR 0,59; IC95% 0,47 - 0,73) y estatinas (OR 0,78;IC95% 0,65 - 0,95). La menor administración de estos fármacos también se asoció a una mayor (..) (AU)

Objectives: To determine whether there is a linear association of age and aspirin, beta-blockers, angiotensin-converting enzyme inhibitors and statins; the extent to which elderly patients receive these treatments; and whether age is independently associated with these treatments. Design: A prospective cohort study. Setting: Coronary Unit of two hospitals in the Region of Murcia (Spain).Patients: Consecutive patients admitted with the diagnosis of acute myocardial infarction between January 1998 and January 2008.Interventions: None. Main outcomes: Those related to the administration of aspirin, beta-blockers, angiotens nconverting enzyme inhibitors and statins during stay in the Coronary Care Unit. Results: Regarding the remaining patients, octogenarians received a similar proportion of angiotensin-converting enzyme inhibitors (70.8% vs. 69.3%, p=0.41) and less often aspirin (90.4%vs. 94.6%, p<0.001), beta-blockers (44.4% vs. 69.4%, p<0,001) and statins (47.6% vs. 64.7%,p<0.001). We were only able to demonstrate an abrupt and significant decrease in the use of statins after 80 years of age. Patient age was independently associated with the use of beta blockers (OR 0.59; 95%CI 0.47 - 0.73) and statins (OR 0.78; 95%CI 0.65 - 0.95). The lesser administration of these drugs was also associated with early mortality (OR 0.17, 95%CI 0.09 to0.33 and OR 0.14; 95%CI 0.08 to 0.23, respectively).Conclusions: Octogenarians less often receive aspirin, beta-blockers and statins, though old age was not an independent factor associated with lesser aspirin use (AU)
