Is influenza A(H1N1) pneumonia more severe than other community-acquired pneumonias?
This study confirmed the specific features of critically ill A(H1N1) patients (i.e., young age, pregnancy, obesity). The pandemic did not increase ICU workload compared with other periods. A(H1N1) pneumonia did not have a higher risk of death than CAP of different origin among patients admitted to the ICU.
Our data showed that the blockade of PECAM-1 immediately after kidney reperfusion inhibits tubular regeneration. These observations suggest that transendothelial migration of extrarenal cells could be a precocious and pivotal step in kidney reparation, but also suggest that these extrarenal cells could be essential to the process of tubular regeneration.
