Validación de la Escala Hospitalaria de Ansiedad y Depresión en población mexicana con trastorno de la conducta alimentaria

Eating disorders (ED) are psychiatric diseases characterized by the alteration of the caloric intake. Besides ED have a high comorbidity with depression and anxiety. In Mexico, the Hospital Anxiety and Depression Scale (HADS) has shown to be a valid and reliable instrument in patients with HIV, cancer, and obesity but its psychometric properties have not been assessed in patients with ED, being the latter the aim of this research. A total of 325 patients (Mage = 22.0, SD = 9.7), completed the HADS. Based on principal axis factoring and oblimin rotation the scale yielded 12 items divided into two subscales: Depression (with nine items) and Anxiety (with three items). With this structure was confirmed the internal consistency of the scale (α = 0.88) and the two subscales (α > 0.80), however the items did not group in the same order than they did in the original scale, for this reason the new configuration of the HADS was analyzed in detail based on the features of the population where the scale was examined, this means, in patients with ED.  Los trastornos de la conducta alimentaria (TCA) son trastornos mentales caracterizados por la alteración del patrón de ingesta calórica. A su vez, los TCA presentan una alta comorbilidad con la depresión y la ansiedad. En México, la Escala Hospitalaria de Ansiedad y Depresión (HADS) ha mostrado ser un instrumento de evaluación válido y confiable en pacientes con VIH, cáncer u obesidad, pero no se han examinado sus propiedades psicométricas en pacientes con TCA, siendo éste el objetivo del presente trabajo. Participaron 325 pacientes (Medad = 22.0, DE = 9.7), quienes completaron la HADS. Con base a análisis de componentes principales, con rotación oblimin, la escala quedó conformada por 12 reactivos divididos en las dos subescalas predichas: Depresión (con nueve ítems) y Ansiedad (con tres ítems). Con base a esta estructura, se confirmó la consistencia interna tanto de la escala (α = 0.88), como de sus dos subescalas (α > 0.80). Sin embargo los reactivos no se agruparon de forma similar que en la escala original, por lo que se analiza a detalle la reconfiguración de la HADS a la luz de las características de la población con TCA en que se examinó la escala

Validation of the Hospital Anxiety and Depression Scale in Mexican population with eating disorders / Validación de la Escala Hospitalaria de Ansiedad y Depresión en población mexicana con trastorno de la conducta alimentaria

Abstract  Eating disorders (ED) are psychiatric diseases characterized by the alteration of the caloric intake. Besides ED have a high comorbidity with depression and anxiety. In Mexico, the Hospital Anxiety and Depression Scale (HADS) has shown to be a valid and reliable instrument in patients with HIV, cancer, and obesity but its psychometric properties have not been assessed in patients with ED, being the latter the aim of this research. A total of 325 patients (Mage = 22.0, SD = 9.7), completed the HADS. Based on principal axis factoring and oblimin rotation the scale yielded 12 items divided into two subscales: Depression (with nine items) and Anxiety (with three items). With this structure was confirmed the internal consistency of the scale (α = 0.88) and the two subscales (α > 0.80), however the items did not group in the same order than they did in the original scale, for this reason the new configuration of the HADS was analyzed in detail based on the features of the population where the scale was examined, this means, in patients with ED.  Resumen  Los trastornos de la conducta alimentaria (TCA) son trastornos mentales caracterizados por la alteración del patrón de ingesta calórica.

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
