Proud to see this published in @cidjournal.bsky.social & with an accompanying commentary!  Nasal decolonization = IP tool MRSA nares = Abx stewardship tool but what happens when they intersect?  Decolonization doesn’t limit usefulness of PCR testing within the first week!

Evaluation of the impact of universal mupirocin decolonization in intensive care units on the utility of MRSA PCR nasal swab testing - PubMed
The NPV of MRSA PCR nasal swabs is not diminished after mupirocin decolonization. MRSA PCR testing within 7 days of initiation of decolonization is non-inferior to testing prior to decolonization.

Delighted to share our latest paper - A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics. Excellently led by Dr. Kuan-Yi Lu. We think it's a great proof-of-concept that altering immune cell behavior can make antibiotics work better www.nature.com/articles/s41...

The authors developed a screen to find compounds that modulate intracellular Staphylococcus aureus metabolism and discovered KL1, which sensitizes persisters to antibiotics by reversing host-induced tolerance.

Very interesting analysis of the opportunity cost of doing an MD-PhD. At the end of the day the choice should be about the type of career you want to have. I have not regretted my choice to get an MD-PhD one bit because it has set me on the perfect path for what I want my career to be!
