Treatment of Cardiogenic Shock: Inotropes, Vasopressors and Machines.
Br J Hosp Med (Lond)

Cardiogenic shock (CS) is associated with significant mortality. Advances in pharmacological therapies and mechanical circulatory support (MCS) devices have markedly improved the therapeutic approach to CS, though treatment efficacy and safety vary. The recent DanGer shock trial showed a significant reduction in 6-month mortality for CS patients due to acute myocardial infarction.

Background: To expand the donor pool, medical centers worldwide are applying marginal donor lungs in clinical settings. We carried out this research to reveal the short-term and long-term outcomes of marginal lung donor transplantation.
Methods: We performed retrospective research using data from patients who underwent lung transplantation (LT) in The Affiliated Wuxi People's Hospital of Nanjing Medical University, Jiangsu Province, China, between 2018 and 2022 to compare the short-term and long-term outcomes of standard donors and marginal donors.
Background: More than 600,000 adults in the United States experience a cardiac arrest each year. After resuscitation from cardiac arrest, most patients receive mechanical ventilation. The oxygenation target that optimizes neurologic outcomes after cardiac arrest is uncertain.

A young female patient suffered cardiogenic shock after undergoing surgery for an ectopic pregnancy. Coronary artery computed tomography angiography (CTA) revealed a left main artery (LM) originating from the right coronary sinus and traveling between the aorta and pulmonary artery. We successfully resuscitated the patient with mechanical circulatory support using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and an intra-aortic balloon pump (IABP).

Lytic polysaccharide monooxygenases (LPMOs) are a unique group of monocopper enzymes that exhibit remarkable ability to catalyze the oxidative cleavage of recalcitrant carbohydrate substrates, such as cellulose and chitin, by utilizing O or HO as the oxygen source. One of the key challenges in understanding the catalytic mechanism of LPMOs lies in deciphering how they activate dioxygen using diverse reductants. To shed light on this intricate process, we conducted in-depth investigations using quantum mechanical/molecular mechanical (QM/MM) metadynamics simulations, molecular dynamics (MD) simulations, and density functional theory (DFT) calculations.
