The benefits of initiating continuous renal replacement therapy after brain death in organ donors with oligoanuric acute kidney injury.

Acute kidney injury (AKI) in deceased organ donors is increasing due to the escalation in anoxic brain-deaths. The management of an organ donor with oligoanuric AKI is frequently curtailed due to hemodynamic and electrolyte instability. Although continuous renal replacement therapy (CRRT) corrects the effects of AKI, it is rarely started after the diagnosis of brain-death (BD).

Resident cardiac macrophages mediate adaptive myocardial remodeling.

Cardiac macrophages represent a heterogeneous cell population with distinct origins, dynamics, and functions. Recent studies have revealed that C-C Chemokine Receptor 2 positive (CCR2) macrophages derived from infiltrating monocytes regulate myocardial inflammation and heart failure pathogenesis. Comparatively little is known about the functions of tissue resident (CCR2) macrophages.
