Is FDG‐PET metabolism associated with cognitive performance in long‐Covid patients?

Background: Current evidence indicates that COVID‐19 infection can lead to neurological complications that persist beyond 12 weeks of infection (long‐COVID), often associated with cognitive decline. However, the underlying mechanisms remain unclear. Our aim is to study the brain metabolism of patients with long‐COVID and its association with cognitive performance.

TIP 4 P 2005 Ice : Simulating water with two molecular states.

Rigid, non-polarizable water models are very efficient from a computational point of view, and some of them have a great ability in predicting experimental properties. There is, however, little room for improvement in simulating water with this strategy, whose main shortcoming is that water molecules do not change their interaction parameters in response to the local molecular landscape. In this work, we propose a novel modeling strategy that involves using two rigid non-polarizable models as states that water molecules can adopt depending on their molecular environment.
