The trihydroxamic acid bacterial siderophore desferrioxamine B (DFOB, 1) produced by the DesABCD biosynthetic cluster coordinates metals beyond Fe(iii), which identifies potential to modify this chelator type to broaden metal sequestration and/or delivery applications. Rather than producing discrete chelators by total chemical synthesis from native monomers including -hydroxy--succinyl-cadaverine (HSC, 2), the recombinant siderophore synthetase from CNB-440 (DesD) was used with different substrate combinations to produce biocombinatorial mixtures of hydroxamic acid chelators. The mixtures were screened with Ga(iii) or Zr(iv) as surrogates of immunological positron emission tomography (PET) imaging radiometals Ga(iii) or Zr(iv) to inform known or new coordination chemistry.

Article Synopsis
  • The study investigates whether ibrutinib-related atrial fibrillation (IRAF) is linked to the dosage of ibrutinib, and if IRAF cases should lead to dosage adjustments or discontinuation of the drug.
  • Researchers analyzed data from the World Health Organization's VigiBase® pharmacovigilance database, focusing on 1,162 IRAF cases and various dosing regimens of ibrutinib (ranging from 140 mg/day to over 560 mg/day).
  • Results indicated that there was no significant association between the reported IRAF cases and the dosage of ibrutinib (p=0.09), suggesting IRAF is not a dose-dependent adverse drug reaction.

Aims: Superior vena cava (SVC) isolation during atrial fibrillation catheter ablation is limited by the risk of collateral damage to the sinus node and/or the phrenic nerve. Due to its tissue-specificity, we hypothesized the feasibility and safety of pulsed-field ablation (PFA)-based SVC isolation.

Methods And Results: One hundred and five consecutive patients undergoing PFA-based AF catheter ablation were prospectively included.
