Accelerating virtual patient generation with a Bayesian optimization and machine learning surrogate model

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 486-494, March 2025.
Abstract The pharmaceutical industry has increasingly adopted model‐informed drug discovery and development (MID3) to enhance productivity in drug discovery and development. Quantitative systems pharmacology (QSP), which integrates drug action mechanisms and disease complexities to predict clinical endpoints and biomarkers is central to MID3.

Cardiorespiratory instability during sleep in infants: Physiological and developmental consequences

Sleep Research, EarlyView.
Abstract During fetal life, autonomic control of the cardio‐respiratory system undergoes rapid maturation and this continues after birth during the first year of life. This underlying immaturity of cardio‐respiratory control leads to an increased risk of cardio‐respiratory instabilities and resultant hypoxaemia during infancy.
