Hyperpolarized [1-C]pyruvate cardiovascular magnetic resonance imaging identifies metabolic phenotypes in patients with heart failure.

Background: Hyperpolarized [1-C]pyruvate cardiovascular magnetic resonance imaging (HP [1-C]pyruvate CMR) visualizes key steps in myocardial metabolism. The present study aimed to examine patients with heart failure (HF) using HP [1-C]pyruvate CMR.

Methods: A cross-sectional study of patients with HF and healthy controls using HP [1-C]pyruvate CMR.

Real-time performance improvement optimizes damage control resuscitation best practice adherence: Results of a pilot prospective observational study.

Background: Maintaining balanced blood product ratios during damage control resuscitation (DCR) is independently associated with improved survival. We hypothesized that real-time performance improvement (RT-PI) would increase adherence to DCR best practice.

Study Design And Methods: From December 2020-August 2021, we prospectively used a bedside RT-PI tool to guide DCR in severely injured patients surviving at least 30 min.

Percutaneous thoracostomy with thoracic lavage for traumatic hemothorax: a performance improvement initiative.

Objectives: Percutaneously placed small-bore (14 Fr) catheters and pleural lavage have emerged independently as innovative approaches to hemothorax management. This report describes techniques for combining percutaneous thoracostomy with pleural lavage and presents results from a performance improvement series of patients managed with percutaneous thoracostomy with immediate lavage.

Methods: This was a prospective performance improvement series of patients treated at a level 1 trauma center with percutaneous thoracostomy and immediate lavage between April 2021 and May 2023.

Thromboembolic Complications Following Perioperative Tranexamic Acid Administration.

Introduction: The antifibrinolytic tranexamic acid (TXA) may reduce death in trauma; however, outcomes associated with TXA use in patients without proven hyperfibrinolysis remain unclear. We analyzed the associations of empirically administered TXA, hypothesizing that TXA use would correlate to lower transfusion totals but increased thromboembolic complications.

Methods: This retrospective cohort study compared trauma patients started on massive transfusion protocol at a Level I trauma center from 2016 to 2021 who either did or did not receive TXA.

Brain-derived extracellular vesicles as serologic markers of brain injury following cardiac arrest: A pilot feasibility study.

Aim: Assessment of neurologic injury within the immediate hours following out-of-hospital cardiac arrest (OHCA) resuscitation remains a major clinical challenge. Extracellular vesicles (EVs), small bodies derived from cytosolic contents during injury, may provide the opportunity for "liquid biopsy" within hours following resuscitation, as they contain proteins and RNA linked to cell type of origin. We evaluated whether micro-RNA (miRNA) from serologic EVs were associated with post-arrest neurologic outcome.
