Empirical Meropenem Versus Piperacillin/Tazobactam for Critically Ill Adults With Sepsis: Feasibility of a Randomised Trial

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 9, October 2026.
ABSTRACT Background Meropenem and piperacillin/tazobactam are commonly used empirical antibiotics in critically ill adults with sepsis, but whether one is superior to the other is uncertain. Methods The Empirical Meropenem versus Piperacillin/Tazobactam for Adult Patients with Sepsis (EMPRESS) trial is an ongoing investigator‐initiated, randomised ...

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.
