Prospective Multicenter Validation of a Simple Blood Test for the Diagnosis of Glut1 Deficiency Syndrome.

Background And Objective: GLUT1 deficiency syndrome (Glut1DS) is a treatable neurometabolic disease that causes a wide range of neurologic symptoms in children and adults. However, its diagnosis relies on an invasive test, that is, a lumbar puncture (LP) to measure glycorrhachia, and sometimes complex molecular analyses of the gene. This procedure limits the number of patients able to receive the standard of care.

Intraosteoblastic activity of daptomycin in combination with oxacillin and ceftaroline against MSSA and MRSA.

Background: The Staphylococcus aureus intracellular reservoir is associated with bone and joint infection (BJI) chronicity. As daptomycin is increasingly prescribed in BJI, strategies for improving its reduced intracellular activity should be promoted.

Objectives: Based on the known in vitro synergy of daptomycin with β-lactams, the aim of the present study was to evaluate the intracellular activity of these combinations in an ex vivo osteoblast infection model.
