RESUMEN
(1) Background: This article discusses the first two phases of development and validation of the Three Domains of Judgment Test (3DJT). This computer-based tool, co-constructed with users and capable of being administered remotely, aims to assess the three main domains of judgment (practical, moral, and social) and learn from the psychometric weaknesses of tests currently used in clinical practice. (2) Method: First, we presented the 3DJT to experts in cognition, who evaluated the tool as a whole as well as the content validity, relevance, and acceptability of 72 scenarios. Second, an improved version was administered to 70 subjects without cognitive impairment to select scenarios with the best psychometric properties in order to build a future clinically short version of the test. (3) Results: Fifty-six scenarios were retained following expert evaluation. Results support the idea that the improved version has good internal consistency, and the concurrent validity primer shows that 3DJT is a good measure of judgment. Furthermore, the improved version was found to have a significant number of scenarios with good psychometric properties to prepare a clinical version of the test. (4) Conclusion: The 3DJT is an interesting alternative tool for assessing judgment. However, more studies are needed for its implementation in a clinical context.
RESUMEN
BACKGROUND: Dilated cardiomyopathy (DCM) is a well described entity for heart failure (HF) with reduced left ventricular ejection fraction (LVEF). Recently, drugs and other substance of abuse have been recognised as potential triggers for DCM. The aim of this study was to assess the survival in patients ≤ 65 years of age with toxic cardiomyopathy (TCM). Left ventricular remodelling and the potential usefulness of left ventricular assist devices (LVADs) was also assessed. METHODS: This was a single-centre retrospective study from January 2003 to August 2019 of 553 patients ≤ 65 years old with LVEF < 40% at a tertiary-care cardiology centre. RESULTS: A total of 201 patients (36%) had a diagnosis of idiopathic DCM. Further analysis identified 38 patients (19%) for which a TCM was the most likely etiology (amphetamine [50%], cocaine [37%], anabolic steroids [8%], and energy drinks [5%]). Despite a mean LVEF of 17 ± 8% at presentation, most patients (n = 27; 71%) had event-free survival with guideline-directed medical therapy, and 61% (n = 23) recovered an LVEF ≥ 40% after a median follow-up of 21 ± 23 months. Seven patients (18%) required an LVAD and 1 patient (3%) a transplantation. All LVADs were explanted or decommissioned after partial or complete LVEF recovery after a median support time of 11 ± 4 months. CONCLUSIONS: TCM induced by substance abuse is a frequent cause of HF, accounting for almost 20% of patients ≤ 65 years of age with DCM of unknown etiology. Treatment must be tailored on an individual basis. Mechanical circulatory support demonstrated its usefulness in carefully selected patients.
