Aims The mortality in cardiogenic shock (CS) is high. role of specific mechanical circulatory support (MCS) systems unclear. We aimed to compare patients receiving Impella versus ECLS (extracorporal life support) with regard baseline characteristics, feasibility, and outcomes CS. Methods results This a retrospective cohort study including CS over 18 years complete follow-up the primary endpoint...

Clinical trials often employ many different endpoints to evaluate the benefits and risks associated with treatment. These endpoints, however, may not always align with one another. In oncology studies, for instance, a more efficacious treatment, which prolongs survival, may also be associated with greater toxicity, which decreases quality of life. Quality-adjusted survival analysis (QASA) provi...

Let K denote a field and let V denote a vector space over K with finite positive dimension. We consider a pair of linear transformations A : V → V and A∗ : V → V that satisfy the following conditions: (i) each of A,A∗ is diagonalizable; (ii) there exists an ordering {Vi} d i=0 of the eigenspaces of A such that A ∗Vi ⊆ Vi−1+Vi+Vi+1 for 0 ≤ i ≤ d, where V−1 = 0 and Vd+1 = 0; (iii) there exists an...
