- Objective: Infants with severe bronchopulmonary dysplasia (sBPD) have complex medical courses. We developed the clinician-rated Optimal State Scoring Tool (OSST) that measures factors relevant to clinical improvement of sBPD and investigated preliminary validity using linear growth outcome and OSST scores in sBPD patients.Methods: Tool development process and pilot findings are provided for 13 patients evaluated longitudinally. OSST scores, length measurements, and steroid dependency values were obtained. Changes in OSST scores and lengths were examined using linear mixed-effect models.Results: OSST scores were significantly correlated with linear growth (95% CI 0.36, 0.57). The steroid-dependent group showed significantly slower rate of linear growth (95% CI 0.74, 1.05) and slower rate of increase in OSST scores (95% CI 0.99, 2.13) compared to the non-steroid-dependent group, with the OSST showing the largest effect size.Conclusion: Pilot data reflect promising evidence for OSST construct validity in monitoring clinical outcomes in sBPD patients.

- Different molecular forms of urinary neutrophil gelatinase-associated lipocalin (NGAL) have recently been discovered. We aimed to explore the nature, source and discriminatory value of urinary NGAL in intensive care unit (ICU) patients. We simultaneously measured plasma NGAL (pNGAL), urinary NGAL (uNGAL), and estimated monomeric and homodimeric uNGAL contribution using Western blotting-validated enzyme-linked immunosorbent assays [uNGAL(E1) and uNGAL(E2)] and their calculated ratio in 102 patients with the systemic inflammatory response syndrome and oliguria, and/or a creatinine rise of > 25 mu mol/L. Bland-Altman analysis demonstrated that, despite correlating well (r = 0.988), uNGAL and uNGAL(E1) were clinically distinct, lacking both accuracy and precision (bias: 266.23; 95 % CI 82.03-450.44 ng/mg creatinine; limits of agreement: -1,573.86 to 2,106.32 ng/mg creatinine). At best, urinary forms of NGAL are fair (area under the receiver operating characteristic [AUROC] a parts per thousand currency sign0.799) predictors of renal or patient outcome; most perform significantly worse. The 44 patients with a primarily monomeric source of uNGAL had higher pNGAL (118.5 ng/ml vs. 72.5 ng/ml; p < 0.001), remaining significant following Bonferroni correction. uNGAL is not a useful predictor of outcome in this ICU population. uNGAL patterns may predict distinct clinical phenotypes. The nature and source of uNGAL are complex and challenge the utility of NGAL as a uniform biomarker.

- Context: Cardiac surgery. Objective: To compare plasma and urinary neutrophil gelatinase-associated lipocalin (P-/U-NGAL) in on-pump (n = 43) versus off-pump (n = 40) surgery. Materials and methods: We obtained perioperative P-/U-NGAL and outcome data. Results: P-/U-NGAL increased after surgery. P-NGAL was higher post-surgery in on pump patients (139 versus 67 mu g L-1; p<0.001), but not at 24 h. There were no differences in U-NGAL. Correlation between P-/U-NGAL and plasma creatinine was weak. Discussion: P-NGAL acts like a neutrophil activation biomarker and U-NGAL like a tubular injury marker. Conclusion: On-pump patients had greater neutrophil activation. On-versus off-pump surgery had similar impact on tubular cells.
