There were no significant differences between the sensitivities (P = 0.84) and the specificities (P = 0.18) for the ventilation and the non-ventilation pauses.

Conclusion: Chest compression pauses are frequent and of sufficient duration to launch a high-temporal resolution Angiogenesis inhibitor SAA. During these pauses rhythm analysis was reliable. Pre-shock pauses could be minimised by analysing the rhythm during ventilation pauses when CPR is delivered at 30: 2 compression: ventilation ratio. (C) 2013 Elsevier Ireland Ltd.

“OBJECTIVES: We aimed to identify a phenotype of ascending thoracic aortic aneurysm (TAA), which, more than others, evolves into type A dissection (TAD).

METHODS: Aortic specimens were obtained from patients undergoing surgical repair of TAA and TAD (108 and 26, respectively). Histopathological and immunohistochemical analyses

were performed by using adequate tissue specimens, appropriate techniques and criteria.

RESULTS: We identified the three following TAA phenotypes: phenotype I (cystic medial degeneration balanced by a substitutive fibrosis, in absence of medial apoptosis and with a faint collagenase concentration), phenotype II (cystic medial degeneration of higher grade, respectively, than substitutive fibrosis, with focal medial apoptosis and moderate collagenase concentration), and phenotype III (elevated cystic medial 3-MA cost degeneration without substitutive fibrosis, with plurifocal medial apoptosis and severe collagenase concentration). The same medial degenerative lesions of TAA phenotype III were observed in TAD tissue samples.

CONCLUSIONS: The morphological identity of medial lesions observed in both the TAA phenotype III and in TAD aortas might be assumed to be the precursor-and consequently the optimal biomarker-of dissection, independently of aneurysm diameter or valvular disorder. Identification of genetic risk factors, useful both in diagnostics

and in developing more targeted treatment for individual patients, might also be needed.”
“Background and objective: We evaluated the efficacy and safety of everolimus, a macrocyclic proliferation signal inhibitor with anti-fibroproliferative activity to prevent disease progression or death in patients with IPF, a progressive, BMS-777607 datasheet fatal disease with no known effective therapy.

Methods: Eighty-nine patients with surgical lung biopsy confirmed IPF were enrolled in a 3-year investigator-driven, placebo-controlled, double-blinded, multicentre study of everolimus.

Results: The everolimus (n = 44) and placebo (n = 45) groups were matched for demographic variables (gender, P = 0.46) and baseline lung function parameters (FVC, P = 0.29; TLC, P = 0.45; DLCO, P = 0.41 and PaO(2), P = 0.34). Independent risks for disease progression were everolimus (hazard ratio (HR) 2.37, 95% CI: 1.40-4.00, P < 0.01, log rank) and male gender (HR 2.76, 95% CI: 1.47-5.17, P < 0.01, log rank).
