Introduction And Objectives: To investigate the relationship between the prevalence of cocaine use disorders and acute myocardial infarction in patients aged ≥ 18 years and to estimate the influence of cocaine use disorders on mortality, excess length of stay, and overexpenditure among hospitalized patients with acute myocardial infarction.

Results: Among 5 575 325 admissions reviewed, there were 24 126 patients with cocaine use disorders and 79 076 cases of acute myocardial infarction.

Subjectivity in the perception and measurement of quality of life: conceptualization and development of the Seville questionnaire.

Quality of life (QoL) is a significant parameter in estimating the social and interpersonal impact of psychopathology, clinical course, and response to treatment in many mental illnesses, particularly schizophrenia. The clinician's assessment and patient's subjective report are essential ingredients of this process. We describe the development and structure of a QoL questionnaire based on the patient's subjective understanding of the problems.
