Comparative Study
Charlson Comorbidity Index is a predictor of outcomes in incident hemodialysis patients and correlates with phase angle and hospitalization.
The adjustment of comorbidity is important in international hemodialysis comparisons. The aim of this study is to verify if it is possible to use the Charlson Comorbidity Index (CCI), in an Italian population of incident hemodialysis patients from the Campania region as outcome predictors. A similar proposal has already been made for an American population of incident patients in peritoneal dialysis. ⋯ We found that CCI is a strong predictor of mortality in incident HD patients as has also been indicated in PD patients; CCI correlates with phase angle calculated from Bioelectrical Impedance Analysis and this last factor can be used in the following examinations; several days of hospitalization are a very important determinant in the survival in hemodialysis patients.

Case Reports
Aortic valve replacement and perioperative management in hemodialyzed patient wth antiphospholipid syndrome.
Antiphospholipid syndrome is characterized by the presence of antiphospholipid antibodies, hypercoagulability, and prolonged phospholipid-dependent coagulation indices such as activated clotting time (ACT). Perioperative thrombotic complications are frequent among patients with antiphospholipid syndrome submitted to cardiac surgery, therefore, in these patients, heparin-protamine titration for anticoagulation monitoring is particularly recommended. ⋯ In our patient celite ACT and heparin concentration during cardiopulmonary bypass did not correspond to each other. Anticoagulation based on heparin concentration assessment resulted in safe perioperative hemostatic management.

Many issues plague the pediatric ARF outcome literature, which include data only from single center sources, a relative lack of prospective study, mixture within studies of renal replacement therapy modality without stratification and inconsistent use of methods to control for patient illness severity in outcome analysis. Since January 2001, the Prospective Pediatric CRRT (ppCRRT) Registry Group has been collecting data from multiple United States pediatric centers to obtain demographic data regarding pediatric patients who receive CRRT, assess the effect of different CRRT prescriptions on circuit function and evaluate the impact of clinical variables on patient outcome. The aim of the current paper is to describe the ppCRRT Registry design, review the decision process and rationale for the options chosen for the ppCRRT format and discuss the analysis plan and future projects envisioned for the ppCRRT Registry.
