Safety and performance of the Clearum™ high flux hemodialyzer
Bibliographic record
Abstract
BACKGROUND: Clearum™ is a high flux steam sterilized dialyzer for patients with hemodialysis or hemodiafiltration. This study evaluated the safety and performance of the Clearum high flux steam sterilized hemodialyzer in the removal of small and middle-sized toxins. METHODS: A prospective, interventional, nonrandomized study enrolled twenty end-stage renal disease patients undergoing hemodialysis. The Clearum high flux steam sterilized dialyzer was compared to Fresenius FX dialyzers for baseline comparison. The duration of the trial was 2 weeks for the FX dialyzer and 6 weeks with the Clearum high flux steam sterilized dialyzer. In vitro studies with dextrans of varying sizes were performed to compare the membrane characteristics and sieving coefficient curves for the two dialyzers. RESULTS: The primary objective of a mean urea reduction ratio >65% was met, with no significant difference in mean urea reduction ratio between the Clearum high flux steam sterilized and Fresenius FX-series of dialyzers (p = 0.86). No dialyzer-related adverse events were reported in the study. β-2-microglobulin reduction with the Clearum high flux steam sterilized dialyzer was statistically higher than the FX-series dialyzer (66.5% vs. 53.6%; p < 0.0001). Predialysis interleukin-6 and C-reactive protein concentrations, blood-rest scores (residual blood after blood restitution), and thrombin-anti-thrombin values were comparable. Albumin remained stable during the 6 weeks of Clearum high flux steam sterilized dialyzer use, with no appreciable differences compared to the Fresenius FX-series. CONCLUSION: The Clearum high flux steam sterilized dialyzer showed good mid-term effectivity for small and middle molecule removal with no reported dialyzer-related adverse events.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
