“Background: The term acute aortic syndrome (AAS) encompasses a range of conditions that have a risk of imminent aortic rupture and where delays in treatment result in increased mortality. Endovascular treatment offers an attractive alternative to open surgery but little is known about the durability of the repair learn more and the factors that predict mortality.

Methods: Prospective data were collected for a cohort of 110 consecutive patients with endovascular treatment for AAS. Patient and procedural characteristics were related to short- and midterm outcome using rnultivariate logistic regression analysis.

Results: There

were 75 men and 35 women with a median age of 68 (range 57-76) years. The pathologies treated were acute dissection (35), symptomatic aneurysm (32), infected aneurysm (18), transection (12), chronic dissection (9), penetrating Selonsertib in vivo ulcer (3), and intramural hematoma (1). Thirty-day mortality was 12.7% and this was associated with hypotension

(odds ratio [OR], 5.25), use of general anesthetic (OR, 5.23), long procedure duration (OR, 2.03), and increasing age (OR, 1.07). The causes of death were aortic rupture (4), myocardial infarction (4), stroke (3), and multisystenn organ failure (3). The stroke and paraplegia rates were 7.3% and 6.4%, respectively. The 1-year survival was 81% and the 5-year survival 63%. Secondary procedures were required in 13 (11.8%) patients. Factors associated with death at 1 year were presence of an aortic fistula (OR, 9.78), perioperative stroke (OR, 5.87), and use of general anesthetic (OR, 3.76); and at 5 years were aortic fistula (OR, 12.31) and increasing age (OR, 1.06).

Conclusions: Hippo pathway inhibitor Acute aortic syndrome carries significant early and late mortality. Emergency endovascular repair offers a minimally invasive treatment option associated with acceptable short and midterm results. Continued surveillance is important as secondary procedures and aortic-related deaths continue to occur throughout the follow-up period. (J Vasc Surg 2011;54:1580-7.)”
“Respiratory viruses represent

one of the most substantial infectious disease burdens to the human population today, and in particular, seasonal and pandemic influenza viruses pose a persistent threat to public health worldwide. In recent years, advances in techniques used in experimental research have provided the means to better understand the mechanisms of pathogenesis and transmission of respiratory viruses, and thus more accurately model these infections in the laboratory. Here, we briefly review the model systems used to study influenza virus infections, and focus particularly on recent advances that have increased our knowledge of these formidable respiratory pathogens.”
