Sarcopenia predicts poor long-term survival in patients undergoing endovascular aortic aneurysm repair

August 25, 2017 - 00:00
Sarcopenia measured by decreased psoas muscle size has been used as a surrogate for frailty and correlates with adverse outcomes in both the short and long term after many major operations. Our aim was to evaluate this measure as a predictor of outcomes in patients undergoing endovascular aortic aneurysm repair (EVAR).

Bacterial signatures in thrombus aspirates of patients with lower limb arterial and venous thrombosis

August 25, 2017 - 00:00
Increasing data supports the role of bacterial inflammation in adverse events of cardiovascular and cerebrovascular diseases. In our previous research, DNA of bacterial species found in coronary artery thrombus aspirates and ruptured cerebral aneurysms were mostly of endodontic and periodontal origin, where Streptococcus mitis group DNA was the most common. We hypothesized that the genomes of S mitis group could be identified in thrombus aspirates of patients with lower limb arterial and deep venous thrombosis.

Role of TGFBR1 and TGFBR2 genetic variants in Marfan syndrome

August 25, 2017 - 00:00
Genetic variants in transforming growth factor beta (TGF-β) receptors type 1 (TGFBR1) and type 2 (TGFBR2) genes have been associated with different hereditary connective tissue disorders sharing thoracic aortic aneurysm and dissection (TAA/D). Mutations in both TGFBR1/2 genes have been described in patients with TAA/D and Marfan syndrome (MFS), and they are associated consistently with Loeys-Dietz syndrome. The existing literature shows discordant data resulting from mutational screening of TGFBR1/2 genes in patients with MFS.
