Network systems can exhibit memory effects in which the interactions between different pairs of nodes adapt in time, leading to the emergence of preferred connections, patterns, and subnetworks. To a first approximation, this memory can be modeled through a "plastic" Hebbian or homophily mechanism, in which edges get reinforced proportionally to the amount of information flowing through them. However, recent studies on glia-neuron networks have highlighted how memory can evolve due to more complex dynamics, including multilevel network structures and "metaplastic" effects that modulate reinforcement.

We reviewed the epidemiological, clinical, microbiological and therapeutic data of cutaneous diphtheria cases, in adult patients living in metropolitan France with a skin sample positive for corynebacteria of the complex between 2018 and 2022.

- The study evaluates the reliability of partial, anonymized mobility data while comparing two methods for identifying spatial communities based on movement: Greedy Modularity Clustering (GMC) and Critical Variable Selection (CVS).
- Using data from Facebook and the Italian National Institute of Statistics, the research analyzes mobility patterns of Italians during the SARS-CoV-2 pandemic, demonstrating the effects of network pruning on population density estimations.
- The findings reveal that despite differences between GMC and CVS methods, both yield similar results in identifying community structures, which can help inform effective policy decisions regarding lockdown measures.
Tracheal stenosis is commonly caused by injury, resulting in inflammation and fibrosis. Inhibiting inflammation and promoting epithelization can reduce recurrence after initial successful treatment of tracheal stenosis. Steroids play an important role in tracheal stenosis management.

- Major peripheral nerve injury (PNI) presents difficulties in functional restoration due to slow axon growth and degeneration of the regenerative pathway without axons.
- Researchers are creating tissue-engineered nerve grafts (TENGs) using porcine neurons and stretching techniques to provide living axons that help guide the regeneration of host axons and maintain nerve pathways.
- TENGs have shown success in accelerating axon regeneration across both short (1 cm) and long (5 cm) nerve defects in pigs, achieving recovery comparable to traditional autograft methods, and showing promise for treating currently unrepairable PNIs.
