Dialysis Efficiency of AN69, a Semisynthetic Membrane Not Well Suited for Diffusion

AN69 membrane is not suited for diffusion, with an suggested limit at 25 mL/min dialysate flow rate. When prescribing continuous hemodialysis this threshold must be surpassed to achieve. We designed a study aimed to check if a higher dose of dialysis could be delivered efficiently with this membrane. Ten ICU patients under continuous hemodiafiltration with 1.4 m(2) AN69 membrane were included a...

Treatment of severe dialysis reactions with the AN69-ST membrane: biocompatibility does matter

Dialysis reactions with biocompatible membranes are rare, and complement activation has been suggested to be a culprit. We report here a case of an incident haemodialysis patient with asthma disease who experienced severe adverse reactions late into dialysis session, with different synthetic membranes (FX 80, Fresenius; Polyflux 17L, Gambro; FX 10, Fresenius; BLS 512, Bellco-Sorin). After repla...

Kriging is well-suited to parallelize optimization

Beyond both estalished frameworks of derivative-based descent and stochastic search algorithms, the rise of expensive optimization problems creates the need for new specific approaches and procedures. The word ”expensive” —which refers to price and/or time issues— implies severely restricted budgets in terms of objective function evaluations. Such limitations contrast with the computational bur...
