[Diagnostic validity and usefulness of the Eating Attitudes Test-26 for the assessment of eating disorders risk in a Colombian female population]. / Validez y utilidad diagnóstica de la escala EAT-26 para la evaluación del riesgo de trastornos de la conducta alimentaria en población femenina de Medellín, Colombia.

OBJECTIVE: To establish diagnostic validity and usefulness of EAT-26 for the risk assessment of Eating Disorder (ED) in a female population. DESCRIPTION: Observational validation study questionnaire. SETTING: Performed in a Medellin city community care level of mixed (public and private) psychiatric consultation. SUBJECTS: Twenty five subjects aged 15 to 25 with DSM-IV-TR diagnostic criteria for anorexia and bulimia nervosa and 111 controls without ED. MAIN OUTCOMES MEASURES: The case sample was for convenience and in controls an aleatory simple one. Gold standard (structured psychiatrist interview confirming the fulfillment of ED case inclusion criteria) was compared with EAT-26 questionnaire; reliability was assessed, cultural, semantics and factorial validation was made and the best cut-off score was established with the ROC curve. RESULTS: Four domains remain in the instrument: bulimia, dieting, food preoccupation and oral control. The Cronbach's alpha was 92.1% and a score of 11 and over is the best cut-off (sensitivity 100%, and specificity 85.6%). CONCLUSIONS: This modified and abbreviated EAT-26 questionnaire is an ideal multidimensional instrument for ED screening in risk population, with excellent reliability and sensitivity values and satisfactory specificity. EAT-26 is a useful measure to be considered when strategies for ED early detection are implemented in young women.

Clinical Utility of HeartLogic, a Multiparametric Telemonitoring System, in Heart Failure.

Telemonitoring through multiple variables measured on cardiac devices has the potential to improve the follow-up of patients with heart failure. The HeartLogic algorithm (Boston Scientific), implemented in some implantable cardiac defibrillators and cardiac resynchronisation therapy, allows monitoring of the nocturnal heart rate, respiratory movements, thoracic impedance, physical activity and the intensity of heart tones, with the aim of predicting major clinical events. Although HeartLogic has demonstrated high sensitivity for the detection of heart failure decompensations, its effects on hospitalisation and mortality in randomised clinical trials has not yet been corroborated. This review details how the HeartLogic algorithm works, compiles available evidence from clinical studies, and discusses its application in daily clinical practice.

Validez y utilidad diagnóstica de la escala EAT-26 para la evaluación del riesgo de trastornos de la conducta alimentaria en población femenina de Medellín, Colombia / Diagnostic validity and usefulness of the Eating Attitudes Test-26 for the assessment of eating disorders risk in a Colombian female population

OBJETIVO: Evaluar la validez y la utilidad diagnóstica de la escala EAT-26 para la evaluación del riesgo de trastornos de conducta alimentaria (TCA) en población femenina. DISEÑO: Estudio observacional de validación de pruebas. Emplazamiento: Realizado en la ciudad de Medellín en nivel de atención comunitaria de consulta psiquiátrica mixta (pública y privada). Participantes: Veinticinco mujeres con edades entre 15 y 25 años que cumplieran criterios DSM-IV-TR para anorexia y bulimia nerviosa y 111 controles sin TCA. Mediciones principales: La muestra de casos fue por conveniencia y en controles, aleatoria simple. Se comparó el «criterio de oro» (entrevista estructurada por psiquiatra para determinar el cumplimiento o no de criterios de inclusión de caso de TCA) con el EAT-26, y al instrumento se le hizo validación cultural y semántica, validación factorial, evaluación de confiabilidad, así como determinación del mejor punto de corte por medio de la curva ROC. RESULTADOS: En EAT-26 subyacen 4 dominios: bulimia, dieta, preocupación por la comida y control oral. El alfa de Cronbach fue de 92,1%, y el mejor valor de corte, el de 11 y más puntos (sensibilidad del 100% y especificidad del 85,6%). CONCLUSIÓN: El EAT-26 modificado y abreviado es un instrumento multidimensional, con excelentes valores de confiabilidad y sensibilidad, y con un adecuado valor de especificidad, apropiado para el cribado de posible TCA en población de riesgo y útil en atención primaria para su detección temprana en mujeres jóvenes
