Low Stroke Volume Predicts Deterioration in Intermediate-Risk Pulmonary Embolism: Prospective Study.

Introduction: Prognosis and management of patients with intermediate-risk pulmonary embolism (PE) is challenging. We investigated whether stroke volume may be used to identify the subset of this population at increased risk of clinical deterioration or PE-related death. Our secondary objective was to compare echocardiographic measurements of patients who received escalated interventions vs anticoagulation monotherapy.

Effectiveness of team-focused CPR on in-hospital CPR quality and outcomes.

Objective: We sought to identify changes in neurological outcome over time following initial training and subsequent implementation of team-focused CPR in an inpatient setting where responders practice specific roles with emphasis on minimally interrupted chest compressions and early defibrillation.

Methods: This retrospective pre- vs post-intervention study was conducted at an urban 900-bed teaching hospital and Level I Cardiac Resuscitation Center. We included adult patients suffering in-hospital cardiac arrest occurring in non-emergency department and non-intensive care unit areas who received CPR and/or defibrillation.

Comparison of Treatment Approaches and Subsequent Outcomes within a Pulmonary Embolism Response Team Registry.

Objectives: To characterize the association between pulmonary embolism (PE) severity and bleeding risk with treatment approaches, outcomes, and complications.

Methods: Secondary analysis of an 11-hospital registry of adult ED patients treated by a PE response team (August 2016-November 2022). Predictors were PE severity and bleeding risk.

Highly compliant biomimetic scaffolds for small diameter tissue-engineered vascular grafts (TEVGs) produced via melt electrowriting (MEW).

Biofabrication approaches toward the development of tissue-engineered vascular grafts (TEVGs) have been widely investigated. However, successful translation has been limited to large diameter applications, with small diameter grafts frequently failing due to poor mechanical performance, in particular mismatched radial compliance. Herein, melt electrowriting (MEW) of poly(-caprolactone) has enabled the manufacture of highly porous, biocompatible microfibre scaffolds with physiological anisotropic mechanical properties, as substrates for the biofabrication of small diameter TEVGs.

Photo-Cross-Linkable, Injectable, and Highly Adhesive GelMA-Glycol Chitosan Hydrogels for Cartilage Repair.

Hydrogels provide a promising platform for cartilage repair and regeneration. Although hydrogels have shown some efficacy, they still have shortcomings including poor mechanical properties and suboptimal integration with surrounding cartilage. Herein, hydrogels that are injectable, cytocompatible, mechanically robust, and highly adhesive to cartilage are developed.
