Physicochemical stability of bevacizumab biosimilar CT-P16 (Vegzelma) concentrate for solution stored in original vials after first opening.

Objective: After patent expiry of the bevacizumab originator product, several biosimilars were approved by the European Medicines Agency. In centralised preparation units, product-specific in-use stability data must be considered. Based on the available data, stability information was missing for the concentrate for solution of the bevacizumab biosimilar CT-P16 (Vegzelma, Celltrion) after first opening and prolonged storage.

Emotional deficits in psychopathy and sexual sadism: implications for violent and sadistic behavior.

While both psychopaths and sexual sadists engage in acts of predatory violence, little empirical work has examined the relationship between the two disorders. This paper outlines the constructs of psychopathy and sexual sadism and reviews the literature investigating the emotional lives of individuals with these disorders, paying particular attention to how emotional deficits might facilitate instrumental violence. Specifically, it is hypothesized that the emotion recognition and emotional experience deficits found among psychopaths, and perhaps present in sexual sadists, may lead to deficits in their ability to empathize with others, resulting in an increased likelihood for perpetrating instrumental violence.
