PK & PK-PD

Real-time continuous in vivo drug monitoring

Dear All:  I recently became aware of a technology for real-time continuous in vivo monitoring of drug levels that I thought worth sharing with the broader community. Although we’ve for many years had continuous measures of analytes such as glucose or oxygen where simple chemistry gave a suitable measurement tool, measurement of arbitrary analytes has

Language matters: CRE vs. CPE; SDD vs. I; and MDR, XDR, PDR, UDR vs. DTR

Note: See also these related newsletters: 13 Jan 2019 (link) on DTR as part of the language of resistance and 7 June 2020 (link) on using DTR to estimate antibiotic value. Dear All (wonk-ish note alert!), Three technical points for your consideration today. All focus on the subtleties of language, something I always find fascinating

It’s really hard to capture the full debate, but here is a brief slide set and as well a written summary of the meeting that provide the main points. More materials can be found online at this

PK measures in space and time: Summary of high-resolution methods

Dear All:  I recently sent around discussions of ways to measure/estimate drug concentrations both in living animals (aptamer-based probes, Kevin Plaxco’s group) and with sufficient spatial resolution to permit construction of 2d/3d drug concentration maps (MALDI-MSI, David Perlin’s group). In the context of our efforts to learn to better apply PK-PD (e.g., the 14-15 June 2017 NIAID PK-PD workshop),
