Safety of prolonged outpatient courses of intravenous antibiotics: a prospective cohort study.

Objectives: The perceived need for prolonged intravenous antibiotic courses has become a major driver behind the growth of outpatient parenteral antimicrobial therapy (OPAT) services. Several recent randomized controlled trials demonstrate noninferiority of an early switch to oral therapy and highlight the need to accurately quantify harms associated with OPAT.

Methods: We conducted a 10-year prospective cohort study in a tertiary hospital OPAT service.

Reversing binding sensitivity to A147T translocator protein.

The translocator protein (TSPO) is a target for the development of neuroinflammation imaging agents. Clinical translation of TSPO PET ligands, such as [C]DPA-713, has been hampered by the presence of a common polymorphism (A147T TSPO), at which all second-generation TSPO ligands lose affinity. Little is known about what drives binding at A147T compared to WT TSPO.
