    • The detection of panels of inflammatory biomarkers such as cytokines has potential for the rapid and specific diagnostic of several devastating diseases such as primary cancers and/or metastatic tumors, as opposed to less serious conditions. For point-of-care clinical applications, the detection of these biomarkers requires a combination of pg/mL sensitivities and multiplexing capabilities, coupled with fit-for-purpose signal transduction strategies. Here, we report the development of a versatile centrifugal microfluidic platform combined with nanoporous microbeads for immunoaffinity-based profiling of cytokines. The device allows sample and analyte multiplexing and detection limits below 1 ng/mL were achieved within 30 minutes, using colorimetric detection.

  • A comparison of very old patients admitted to intensive care unit after acute versus elective surgery or intervention
  • 2019
  • Ingår i: Journal of critical care. - : W B SAUNDERS CO-ELSEVIER INC. - 0883-9441 .- 1557-8615. ; 52, s. 141-148
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: We aimed to evaluate differences in outcome between patients admitted to intensive care unit (ICU) after elective versus acute surgery in a multinational cohort of very old patients (80 years; VIP). Predictors of mortality, with special emphasis on frailty, were assessed.Methods: In total, 5063 VIPs were induded in this analysis, 922 were admitted after elective surgery or intervention, 4141 acutely, with 402 after acute surgery. Differences were calculated using Mann-Whitney-U test and Wilcoxon test. Univariate and multivariable logistic regression were used to assess associations with mortality.Results: Compared patients admitted after acute surgery, patients admitted after elective surgery suffered less often from frailty as defined as CFS (28% vs 46%; p < 0.001), evidenced lower SOFA scores (4 +/- 5 vs 7 +/- 7; p < 0.001). Presence of frailty (CFS >4) was associated with significantly increased mortality both in elective surgery patients (7% vs 12%; p = 0.01), in acute surgery (7% vs 12%; p = 0.02).Conclusions: VIPs admitted to ICU after elective surgery evidenced favorable outcome over patients after acute surgery even after correction for relevant confounders. Frailty might be used to guide clinicians in risk stratification in both patients admitted after elective and acute surgery.
