Background And Objectives: Takotsubo syndrome (TTS) is an infrequent cause of acute coronary syndrome much better diagnosed in recent years. This study sought to assess the clinical profile of patients admitted with TTS in Spain and to elucidate potential regional differences in admissions and in-hospital mortality between the years 2008 and 2021.

Methods: Retrospective observational study of patients admitted to acute general hospitals of the Spanish National Health System with a main or secondary diagnosis of STT, using the minimum basic data set.

A Circular Waste Management alternative is considered in this paper in which a complete ash valorization process is proposed for an Integrated Gasification with Combined Cycle fly ash, trying to extract maximum value from this waste before it is discarded. In the paper, germanium, a scarce resource vital in our modern society, is first extracted from fly ash using water, with an extraction yield of 85%, and subsequently, the leached fly ash is used in the manufacture of fire-resistant boards containing 60% ash, thereby avoiding its disposal in a landfill. The potential environmental impact caused by the two stages of the process was analyzed, and the final effluent was considered to achieve a zero-discharge objective.
