AI Article Synopsis

  • The study analyzed 199 patients on ECMO support, revealing a high mortality rate of 76.38% and identified key risk factors for mortality.
  • Continuous renal replacement therapy (CRRT) and age were found to be independent risk factors, with age having the strongest predictive ability for death at a cutoff of 48.5 years.
  • Additionally, patients on combined CRRT and ECMO without congenital heart disease or a previous surgical history faced increased mortality risks.

Article Abstract

Objective: Patients on extracorporeal membrane oxygenation (ECMO) are often complex and have a high mortality rate. Currently, risk assessment and treatment decisions for patients receiving ECMO are controversial. Therefore, we sought to identify risk factors for mortality in patients receiving ECMO and provide a reference for patient management.

Methods: We retrospectively analyzed the clinical data of 199 patients who received ECMO support from December 2013 to April 2023. Univariate and multivariable logistic regression analyses were used to identify risk factors. The cutoff value was determined by receiver operating characteristic (ROC) curve analysis.

Results: A total of 199 patients were selected for this study, and the mortality rate was 76.38%. More than half of the patients underwent surgery during hospitalization. Multivariable logistic regression analysis revealed that continuous renal replacement therapy (CRRT) implantation (OR = 2.994; 95% CI, 1.405-6.167;  = 0.004) and age (OR = 1.021; 95% CI, 1.002-1.040;  = 0.032) were the independent risk factors for mortality. In the ROC curve analysis, age had the best predictive effect (AUC 0.646, 95% CI 0.559-0.732,  = 0.003) for death when the cutoff value was 48.5 years. Furthermore, in patients receiving combined CRRT and ECMO, lack of congenital heart disease and previous surgical history were the independent risk factors for mortality.

Conclusions: CRRT implantation and age were independent risk factors for patients with ECMO implantation in a predominantly surgical cohort. In patients receiving a combination of CRRT and ECMO, lack of congenital heart disease and previous surgical history were independent risk factors for mortality.

Plasma brain-related biomarkers and potential therapeutic targets in pediatric ECMO.

Extracorporeal membrane oxygenation (ECMO) is a technique used to support severe cardiopulmonary failure. Its potential life-saving benefits are tempered by the significant risk for acute brain injury (ABI), from both primary pathophysiologic factors and ECMO-related complications through central nervous system cellular injury, blood-brain barrier dysfunction (BBB), systemic inflammation and neuroinflammation, and coagulopathy. Plasma biomarkers are an emerging tool used to stratify risk for and diagnose ABI, and prognosticate neurofunctional outcomes.

Introduction: Prior analysis of children with grade 3 and 4 congenital hydronephrosis demonstrated that renal medullary pyramidal thickness (PT) is predictive of subsequent pyeloplasty (area under the curve [AUC] = 0.78). The objective of this study was to further analyze the utility of sonographic measurements including PT, anteroposterior pelvic diameter (APD), and renal length with an expansion of the number of infants with hydronephrotic kidneys including grades 2, 3, and 4 hydronephrosis.

Background: Lymph node ratio (LNR), log odds of positive lymph nodes (LODDS), and the number of postoperative lymph node staging (pN) are prognostic indicators of various cancers. However, the prognostic values of these indicators remain unclear in hypopharyngeal squamous cell carcinoma (HPSCC). This study's primary objective was to investigate the predictive value of LNR, LODDS, and pN for advanced HPSCC, and the secondary objective was to compare which of the values had the best predictive value for advanced HPSCC.

Background: Pseudarthrosis is a major complication after posterior lumbar interbody fusion (PLIF) and transforaminal interbody fusion (TLIF), and its risk factors need to be identified. This study aimed to investigate the relationship between the number of remaining teeth (NRT) and pseudarthrosis.

Methods: NRT, preoperative bone density of the proximal femur (percentages of young adult mean; % YAM), and preoperative procollagen type 1 N-terminal propeptide (P1NP) (μg/L) were retrospectively investigated in 63 patients (24 male and 39 female, mean age: 71.
