Differences in Care and Outcomes in Cardiogenic Shock in Cardiac Intensive Care Units in the United States and Canada: CCCTN Registry Insights.

Background: Mortality in cardiogenic shock (CS) remains high. Significant inter-hospital heterogeneity in critical care therapies have been described, which reflects the lack of high-quality evidence to guide optimal treatment. We aimed to describe differences in practices and clinical outcomes among patients with CS in the United States (US) and Canada.

Individualized transfusion decisions to minimize adverse cardiovascular outcomes in patients with acute myocardial infarction and anemia.

Background: Risk-benefit tradeoffs between restrictive versus liberal red blood cell transfusion strategies may vary across individuals. This exploratory analysis aimed to derive and evaluate individualized treatment effects of defined transfusion strategies in patients with acute MI and anemia with the goal of minimizing adverse cardiovascular outcomes.

Methods: This study analyzed 3,447 (98.

Synthesis of β-Alanine From Isoleucine and Propionate Catabolism via Aminotransferases.

In plants, the nonproteinogenic amino acid β-alanine plays a role in response to hypoxia, flooding, drought, heat, and heavy metal stress conditions. It is also a key intermediate in the synthesis of essential molecules including vitamin B5 and coenzyme A (CoA) through the condensation reaction with pantoate. While the syntheses of pantoate, vitamin B5, and CoA appear to be conserved across plants and bacteria, the synthesis of β-alanine is not.
