Can biodegradable plastics mitigate plastamination? Feedbacks from marine organisms.

The EU plastic strategy aims to reduce the environmental impact of the increasing plastic production, by replacing petrochemical-based polymers with biodegradable ones. But this mitigation measure for the plastamination might, in turn, generate bio-based microplastics in environments that are not necessarily safe. Biodegradable and non-biodegradable plastics, polylactic acid (PLA) and polypropylene (PP) respectively, and their leachates were used for testing microplastic (MP) effects on seven marine species from different trophic levels, including bacteria, algae, rotifers, copepods, amphipods and branchiopods.

The ethical foundations of patient-centered care in aesthetic medicine.

This article addresses some critical aspects of the relationship between aesthetic medicine (AM) and ethics and proposes a possible deontological ethical line to pursue based on current practices. The role of AM has always been controversial and suffers from unclear practical and moral boundaries, even within academic settings, since it aims to improve the appearance of individuals, not to cure a disease. Today, it is essential and pertinent to discuss these issues, as AM specialists are dealing with a growing and increasingly demanding patient population that has undergone profound evolution in recent years.
