A chimney femoral artery graft for peripheral extracorporeal membrane oxygenation can potentially cause hyperperfusion and subsequent venous congestion in the ipsilateral leg, especially in the context of septic shock and higher flow requirement. This report describes a novel technique to use an additional leg venous cannula to avoid leg congestion as well as to achieve higher total flow.

Central or Peripheral Venoarterial Extracorporeal Membrane Oxygenation for Pediatric Sepsis: Outcomes Comparison in the Extracorporeal Life Support Organization Dataset, 2000-2021.

Objectives: Small studies of extracorporeal membrane oxygenation (ECMO) support for children with refractory septic shock (RSS) suggest that high-flow (≥ 150 mL/kg/min) venoarterial ECMO and a central cannulation strategy may be associated with lower odds of mortality. We therefore aimed to examine a large, international dataset of venoarterial ECMO patients for pediatric sepsis to identify outcomes associated with flow and cannulation site.
Design: Retrospective analysis of the Extracorporeal Life Support Organization (ELSO) database from January 1, 2000, to December 31, 2021.
Integrative Analyses of Single-Cell RNA-Sequencing and Bulk RNA-Sequencing Reveal Prognostic Markers of Peripheral Blood Mononuclear Cells in Patients with Cardiogenic Shock Receiving Venous-Arterial Extracorporeal Membrane Oxygenation Support Collected before Venous-Arterial Extracorporeal Membrane Oxygenation Establishment.

The impact of changes in peripheral blood mononuclear cells (PBMCs) on the prognosis of patients with cardiogenic shock (CS) receiving venous-arterial extracorporeal membrane oxygenation (VA-ECMO) remains unclear. A single-cell RNA-sequencing (scRNA-seq) and a bulk RNA-sequencing (bulk RNA-seq) data sets of pre-ECMO PBMCs of CS patients were obtained from the gene expression omnibus database, which were analyzed using the "Seurat" and "limma" packages, respectively. The counts of different PMBC cell types, differential expression genes (DEGs), pathway enrichment analysis, cell-cell communication analysis, pseudotime analysis, and immune cell infiltration analysis were compared between VA-ECMO groups with different prognoses.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

Objective: The study objective was to evaluate outcomes of patients directly bridged with venoarterial extracorporeal membrane oxygenation to heart transplantation.
Methods: A single-center retrospective study was performed on 1152 adult patients undergoing isolated cardiac transplantation between January 2007 and December 2021. Among these, patients bridged with an extracorporeal membrane oxygenation to transplantation (extracorporeal membrane oxygenation group, n = 317) were compared with standard cohorts of patients (no extracorporeal membrane oxygenation group, n = 835).

Article Synopsis
- Sepsis is a severe condition caused by an uncontrolled immune reaction to infections, often involving harmful bacteria like E. coli, and currently lacks effective treatments.
- Researchers developed E. coli wall-derived carbon dots (E-CDs) that can reduce inflammation and improve survival rates in septic mice by binding to immune receptors and preventing excessive immune responses.
- E-CDs also show promise in other models, reducing inflammation and oxidative stress, suggesting they could be a new therapeutic approach for treating sepsis by utilizing pathogen-derived materials.
