Biomarkers of RV Dysfunction in HFrEF Identified by Direct Tissue Proteomics: Extracellular Proteins Fibromodulin and Fibulin-5.

Background: Right ventricular dysfunction (RVD) is common in patients with heart failure with reduced ejection fraction, and it is associated with poor prognosis. However, no biomarker reflecting RVD is available for routine clinical use.

Methods: Proteomic analysis of myocardium from the left ventricle and right ventricle (RV) of patients with heart failure with reduced ejection fraction with (n=10) and without RVD (n=10) who underwent heart transplantation was performed.

Growth Differentiation Factor-15 Is Associated With Congestion-Related Anorexia and Weight Loss in Advanced Heart Failure.

Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.

Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).

Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.

Plasma transfusion in the intensive care unit.

Background: Current guidelines discourage prophylactic plasma use in non-bleeding patients. This study assesses global plasma transfusion practices in the intensive care unit (ICU) and their alignment with current guidelines.

Study Design And Methods: This was a sub-study of an international, prospective, observational cohort.

Intraperitoneal intravenous administration of Flamma®-conjugated PEG-alendronate-coated upconversion nanoparticles in a mouse pancreatic cancer model.

Pancreatic cancer is one of the most common forms of malignant disease with a poor survival prognosis. Currently, nanomedicine holds great promise for targeted diagnosis and treatment of this cancer, which also reduces toxic side effects. In this work, we prepared PEG-coated monodisperse upconversion nanoparticles (UCNPs) with a conjugated Flamma® fluorescent dye for imaging and detection of particle distribution .

Circulating beta-hydroxybutyrate levels in advanced heart failure with reduced ejection fraction: Determinants and prognostic impact.

Aims: Patients with heart failure (HF) display metabolic alterations, including heightened ketogenesis, resulting in increased beta-hydroxybutyrate (β-OHB) formation. We aimed to investigate the determinants and prognostic impact of circulating β-OHB levels in patients with advanced HF and reduced ejection fraction (HFrEF).

Methods And Results: A total of 867 patients with advanced HFrEF (age 57 ± 11 years, 83% male, 45% diabetic, 60% New York Heart Association class III), underwent clinical and echocardiographic examination, circulating metabolite assessment, and right heart catheterization (n = 383).
