Surgical embolectomy for intermediate-risk acute pulmonary embolism.
Recent series reported excellent results of surgical embolectomy in patients with acute pulmonary embolism with mortality rates of about 5-9% (range 0-13%). However, very low mortality of patients receiving medical treatment for intermediate-risk pulmonary embolism (1.5 and 2.8% at 7 and 30 days, respectively) was recently reported. Thus, we would like to challenge the indication for surgical embolectomy in the subset of intermediate-risk patients.

Resveratrol (RSV) has been shown to inhibit the inflammatory reaction and ameliorate the organ damage resulting from trauma-hemorrhage (TH). However, the effects of RSV on the metabolomic profiles under these conditions remain unclear. The aim of this study was to determine the metabolomic profiles of plasma in TH rats and to evaluate the therapeutic effects of RSV using high-performance liquid chromatography-mass spectrometry. ⋯ In addition, RSV treatment reduced ketoacidosis and protein degradation, as evidenced by the attenuation of the elevated plasma branched-chain amino acid levels in the TH rats. Our study showed that the alterations of the metabolomic profiles in the rats subjected to trauma-hemorrhagic shock were attenuated by RSV treatment. In view of the metabolomic evidence, we conclude that RSV exerts beneficial effects in trauma-hemorrhagic shock injury and that these effects are partially mediated by improving energy metabolism and reducing protein degradation.
