Ceramides as Emerging Players in Cardiovascular Disease: Focus on Their Pathogenetic Effects and Regulation by Diet.

Impaired lipid metabolism is a pivotal driver of cardiovascular disease (CVD). In this regard, the accumulation of ceramides within the circulation as well as in metabolically active tissues and atherosclerotic plaques is a direct consequence of derailed lipid metabolism. Ceramides may be at the nexus between impaired lipid metabolism and CVD. Indeed, although on one hand ceramides have been implicated in the pathogenesis of CVD, on the other specific ceramide subspecies have also been proposed as predictors of major adverse cardiovascular events. This review will provide an updated overview of the role of ceramides in the pathogenesis of CVD, as well as their pathogenetic mechanisms of action. Furthermore, the manuscript will cover the importance of ceramides as biomarkers to predict cardiovascular events and the role of diet, both in terms of nutrients and dietary patterns, in modulating ceramide metabolism and homeostasis.

Sex- and Gender-Related Aspects in Pulmonary Hypertension.

Biological sex and sociocultural gender are emerging as pivotal modifiers of health and diseases. Sex-based differences exist in the development, pathogenesis, and management of individuals with pulmonary arterial hypertension (PAH). The interplay between gender domains (ie, identity, roles, relations, and institutionalized gender) and PAH has been barely investigated. The aim of this narrative review is to describe up-to-date evidence on the integration of sex and gender in PAH research, highlighting areas for future investigation.
