The Hyperbilirubinemia and Potential Predictors Influence on Long-Term Outcomes in Sepsis: A Population-Based Propensity Score-Matched Study.

ABSTRACT: Objective: Although hyperbilirubinemia has been associated with mortality in patients who are critically ill, yet no clinical studies dissect the effect of dynamic change of hyperbilirubinemia on long-term septic prognosis. The study aims to investigate the specific stages of hyperbilirubinemia and potential risk factors on long-term outcomes in patients with sepsis. Methods: In this retrospective observational cohort study, patients with sepsis, without previous chronic liver diseases, were identified from the Medical Information Mart for the Intensive Care III MIMIC-III database. We used propensity scores (PS) to adjust the baseline differences in septic patients with hyperbilirubinemia or not. The multivariate Cox was employed to investigate the predictors that influence a clinical outcome in sepsis. Results: Of 2,784 patients with sepsis, hyperbilirubinemia occurred in 544 patients (19.5%). After PS matching, a survival curve demonstrated that patients with sepsis with the new onset of total bilirubin (TBIL) levels more than or equal to 5 mg/dl survived at significantly lower rates than those with TBIL levels <5 mg/dl. Multivariate Cox hazard analysis showed that patients with TBIL at more than or equal to 5 mg/dl during sepsis exhibit 1.608 times (95% CI: 1.228-2.106) higher risk of 1-year mortality than those with TBIL levels <5 mg/dl. Also, age above 65 years old, preexisting malignancy, a respiratory rate above 30 beats/min at admission, serum parameters levels within 24-h admission, containing international normalized ratio (INR) above 1.5, platelet <50^*10^∧9/L, lactate above 4 mmol/L, and bicarbonate <22 or above 29 mmol/L are the independent risk factors for long-term mortality of patients with sepsis. Conclusions: After PS matching, serum TBIL levels at more than or equal to 5 mg/dl during hospitality are associated with increased long-term mortality for patients with sepsis. This study may provide clinicians with some cutoff values for early intervention, which may improve the prognosis of patients with sepsis.

Project description:BackgroundAwareness of treatment group assignment in a clinical trial may influence patient behavior and bias outcome reporting. The objective of this study was to compare 2-year clinical outcomes in blinded vs unblinded patients who were treated with lumbar discectomy and a bone-anchored annular closure device (ACD) for prevention of lumbar disc reherniation.MethodsThis was a secondary analysis of a randomized trial comparing lumbar discectomy with (n=272) vs without (n=278) implantation of a bone-anchored ACD. Among patients who received ACD implantation, 35 (13%) were blinded and 237 (87%) were unblinded to treatment allocation. In patients treated with ACD, propensity score-matching (1:1) was performed to account for imbalances in patient characteristics between blinded and unblinded groups. Key clinical outcomes were back pain severity (0-100 scale), leg pain severity (0-100 scale), Oswestry Disability Index (ODI, 0-100 scale), symptomatic reherniation, reoperation at the treated lumbar level, and device- or procedure-related serious adverse events (AEs). Outcomes were reported through 2 years of follow-up, which coincided with the time at which blinded patients were unblinded.ResultsThere were no statistically significant differences in 2-year outcomes between propensity score-matched blinded (n=35) and unblinded (n=35) patients treated with the ACD. In blinded vs unblinded ACD patients compared to baseline, back pain severity decreased by 40 vs 37 points (P=0.61), leg pain severity decreased by 75 points in each group (P>0.99), and ODI decreased by 47 vs 43 points (P=0.19). The risks of symptomatic reherniation (5.7% vs 9.1%; P=0.59), reoperation (8.6% vs 12.2%, P=0.62), and device- or procedure-related serious AEs (5.7% vs 8.9%, P=0.63) were comparably low in blinded and unblinded patients.ConclusionIn patients treated with lumbar discectomy and a bone-anchored ACD, there were no clinically important or statistically significant differences in back pain, leg pain, ODI, symptomatic reherniation, reoperation, or serious AEs over 2 years of follow-up when comparing patients who were blinded vs unblinded to their treatment assignment. The main limitations of this study were the post hoc nature of the analysis and the potential for bias due to surgeon awareness of treatment assignment.

Project description:BackgroundBrain arteriovenous malformations (AVMs) account for 25% of hemorrhagic strokes in young adults. Although embolization has been widely performed as a stand-alone procedure to cure brain AVM, it is undermined whether patients benefit from this treatment. This study aimed to compare the long-term outcome of hemorrhagic stroke or death in patients with either conservative management or stand-alone embolization for AVM.MethodsThe study population was derived from a nationwide multicenter prospective collaboration registry (the MATCH registry) between August 2011 and August 2021. The propensity score-matched survival analysis was performed in the overall and stratified AVM cases (unruptured and ruptured), respectively, to compare the long-term outcome of hemorrhagic stroke or death, and neurological status. The efficacy of distinct embolization strategies was also evaluated. Hazard ratios (HRs) with 95% CI were calculated using Fine-Gray competing risk models.ResultsOf the 3682 consecutive AVMs, 906 underwent either conservative management or embolization as the stand-alone management strategy. After propensity score matching, a total of 622 (311 pairs) patients constituted an overall cohort. The unruptured and ruptured subgroups were composed of 288 cases (144 pairs) and 252 cases (126 pairs), respectively. In the overall cohort, embolization did not prevent long-term hemorrhagic stroke or death compared with conservative management [2.07 vs. 1.57 per 100 patient-years; HR, 1.28 (95% CI, 0.81-2.04)]. Similar results were maintained in both unruptured AVMs [1.97 vs. 0.93 per 100 patient-years; HR, 2.09 (95% CI, 0.99-4.41)] and ruptured AVMs [2.36 vs. 2.57 per 100 patient-years; HR, 0.76 (95% CI, 0.39-1.48)]. Stratified analysis showed that the target embolization might be beneficial for unruptured AVMs [HR, 0.42 (95% CI, 0.08-2.29)], while the curative embolization improved the outcome of ruptured AVMs [HR, 0.29 (95% CI, 0.10-0.87)]. The long-term neurological status was similar between these two strategies.ConclusionsThis prospective cohort study did not support a substantial superiority of embolization over conservative management for AVMs in preventing long-term hemorrhagic stroke or death.
