RESUMO
Introduction: Carbapenem-resistant Gram-negative bacteria (CRGN) are an urgent public health threat because of the limited treatment options, its rapid spreading and high clinical impact and mortality rates. However, the burden and the use of resources of these infections have not been investigated. The aim of the current study is to understand the use of resources associated to the clinical management of CRGN infections in real clinical practice conditions. Methods: An observational retrospective chart review study was performed. Data regarding patient demographics, clinical management and use of resources associated to hospitalization were retrieved from clinical charts of ICU inpatients with a confirmed CRGN infection. Three reference Spanish hospitals were selected according to their patient volume and geographical coverage. Descriptive analyses of the clinical management and the use of resources and its cost were performed and then total costs by type of resource were calculated. Results: A total of 130 patients were included in the study. The higher number of patients (n=43; 33%) were between 61 and 70 years old. Ninety-four (72%) patients were male and 115 (88%) suffered from comorbidities. The mean total cost associated to the resources used in patients with CRGN infections hospitalized in ICU was 96,878 per patient. These total costs included 84,140 of total hospital stay, 11,021 of treatments (558 of antibiotics; 10,463 of other treatments) and 1717 costs of diagnostic tests. Conclusions: CRGN infection causes a high use of hospital resources, being the length of stay either in hospital wards or ICU the driver of the total costs. Diagnostic tests and treatments, including antibiotics, represent the lowest part of the use of resources and costs (13% of total costs).(AU)
Introducción: Las bacterias gramnegativas resistentes a carbapenémicos (CRGN) son una amenaza urgente de salud pública por las limitadas opciones de tratamiento, su rápida dispersión y el alto impacto clínico y tasas de mortalidad. Sin embargo, la carga y el uso de recursos de estas infecciones no han sido investigadas. El objetivo de este estudio es comprender el uso de recursos asociado al manejo clínico de las infecciones por CRGN en condiciones de práctica clínica real. Métodos: Se llevó a cabo un estudio observacional retrospectivo de revisión de historias clínicas. Se recogieron datos demográficos, del manejo clínico y del uso de recursos asociado a la hospitalización de historias clínicas de pacientes hospitalizados en UCI con una infección confirmada por CRGN. Se seleccionaron tres hospitales españoles de referencia por su cobertura geográfica. Se realizaron análisis descriptivos del manejo clínico y el uso de recursos y sus costes en episodios de infecciones por CRGN, y se calcularon los costes totales para cada tipo de recurso. Resultados: Se incluyeron en el estudio un total de 130 pacientes. La mayoría de los pacientes (n=43;33%) tenían entre 61-70 años. Noventa y cuatro pacientes (72%) eran hombres y 115 (88%) presentaron comorbilidades. El coste medio total asociado a los recursos usados durante el episodio de infección por CRGN por paciente fue de 96.878. Este coste total incluye 84.140 de la estancia en el hospital, 11.021 de los tratamientos (558 de antibióticos y 10.463 de otros tratamientos) y 1.717 del coste de test diagnósticos. Conclusiones: El episodio de infección por CRGN causa un alto uso de recursos hospitalarios, siendo la duración de la estancia tanto en planta hospitalaria como en UCI el factor con mayor peso de los costes totales. Los test diagnósticos clínicos y los tratamientos, incluyendo los antibióticos, representan la parte más pequeña del uso de recursos y sus costes (13% del coste total).(AU)

Background/Objective: Neuroimaging studies have reported abnormalities in the examination of functional connectivity in late-life depression (LLD) in the default mode network (DMN). The present study aims to study resting-state functional connectivity within the DMN in people diagnosed with late-life major depressive disorder (MDD) compared to healthy controls (HCs). Moreover, we would like to differentiate these same connectivity patterns between participants with high vs. low anxiety levels.Method: The sample comprised 56 participants between the ages of 60 and 75; 27 of them were patients with a diagnosis of MDD. Patients were further divided into two samples according to anxiety level: the four people with the highest anxiety level and the five with the lowest anxiety level. Clinical aspects were measured using psychological questionnaires. Each participant underwent functional magnetic resonance imaging (fMRI) acquisition in different regions of interest (ROIs) of the DMN.Results: There was a greater correlation between pairs of ROIs in the control group than in patients with LLD, being this effect preferentially observed in patients with higher anxiety levels.Conclusions: There are differences in functional connectivity within the DMN depending on the level of psychopathology. This can be reflected in these correlations and in the number of clusters and how the brain lateralizes (clustering). (AU)
