Special Issue about Competing Risks and Multi-State Models
No full textThere is a clear growing interest, at least in the statistical literature, in competing risks and multi-state models. With the rising interest in competing risks and multi-state models a number of software packages have been developed for the analysis of such models. The present special issue of the Journal of Statistical Software introduces a selection of R packages devoted to competing risks and multi-state models. This introduction to the special issue contains some background and highlights the contents of the contributions.
Reduced Need for Vasopressors in Patients Receiving Aprotinin during Orthotopic Liver Transplantation
No full textBackground: Graft reperfusion in orthotopic liver transplan- tation is often associated with significant hemodynamic changes, including decreased systemic vascular resistance and arterial blood pressure. Vasopressive drugs are often required to maintain adequate perfusion pressure during the early post- reperfusion period. The exact mechanism of this postreperfu- sion syndrome is unknown, but release of bradykinin, a potent vasodilatator, via the kallikrein system may play a role. Apro- tinin is a broad-spectrum inhibitor of serine proteases such as kallikrein and therefore may ameliorate the postreperfusion syndrome and reduce the need for vasopressors.
Methods: In a randomized, double-blind study, the authors compared hemodynamic variables (systemic vascular resis- tance, cardiac index, arterial blood pressure, mean pulmonary artery pressure, central venous pressure) and the requirement of epinephrine during transplantation in 67 patients who received either high-dose aprotinin (2 106 kallikrein inhibitor units [KIU] at induction, continuous infusion of 1 106 KIU/h, 1 106 KIU before reperfusion; n 24), regular-dose aprotinin (2 106 KIU at induction, continuous infusion of 0.5 106 KIU/h; n 21), or placebo (n 22).
Results: Baseline characteristics were similar for all three groups. Erythrocyte transfusion requirement was significantly higher in the placebo group compared with both aprotinin- treated groups. No major differences in hemodynamic variables were found between the three groups. The total amount of epinephrine (median, range) used during transplantation, how- ever, was significantly lower in patients who received aprotinin (high dose, 20, 0 –170 g; regular dose, 30, 0 –140 g), compared with patients who received placebo (70, 0–2,970 g; P 0.0017). This difference was largely attributable to differences in the early postreperfusion period.
Conclusions: Prophylactic use of aprotinin ameliorates the postreperfusion syndrome in orthotopic liver transplantation, as reflected by a significant reduction in vasopressor requirements
Dynamic aspects of competing risks with application to medical data
No full textM.A. Nicolaie focuses in this thesis on inference in survival models for survival data with competing risks. The author introduces a new approach to competing risks data, called vertical modeling. It is built on natural observable quantities in competing risks, that is, it quantifies 1. the chance that a failure occurs, irrespective of its cause and 2. conditionally that a failure occurred, it quantifies the risk that the event of failure is ascertained to a certain type of failure. Another appealing feature of vertical modeling which is discussed is that it deals with competing risks when missing causes of failure occur. Next, the author tackles the topic of dynamic prediction in competing risks, a topical subject nowadays. She uses two different approaches, one which is based on modeling the cause-specific hazards and one which is based on modeling the dynamic pseudo-observations associated to the cumulative incidence functions. The results presented in this thesis provide key messages on the use of competing risks methods in different fields such as epidemiology, medicine, demography.M.A. Nicolaie focuses in this thesis on inference in survival models for survival data with competing risks.
