Summary: Acute myocardial infarction (MI) is a common and fatal global disease, and heart failure (HF) remains a significant risk despite standard treatment. Cardiac resident macrophages (cMacs) have emerged as key regulators in the pathophysiology of post-MI progression, regulating aspects such as immune cell recruitment, cell clearance, fibrosis, and energy metabolism. Targeting cMacs presents a promising therapeutic strategy, including using nanocarriers to deliver drugs or introducing exogenous protective cMacs through cell therapies.

Summary: The study demonstrates that human cardiac muscle patches containing three types of cardiac cells derived from human pluripotent stem cells significantly improved cardiac function, reduced infarct size, and promoted cardiac maturation in a pig model of myocardial infarction. The inclusion of cardiac fibroblasts in the cardiac patches enhanced the maturity and function of cardiac muscle cells. Transplantation of cardiac patches with cardiac fibroblasts resulted in better cardiac recovery and engraftment compared to patches without fibroblasts.

Summary: In this study, the authors investigated cardiomyocyte mechanosensation in a three-dimensional (3D) context. They found that cardiomyocytes had limited ability to adapt their volume to increasing substrate stiffness in a stiffness gradient GelMA hydrogel. The expression of mechanomarkers was better correlated with cell and nuclear volume than substrate stiffness. Furthermore, when cultured as spheroids, cardiomyocytes showed sensitivity to stiffness cues and exhibited different morphologies compared to individually cultured cells. These findings suggest that cardiac cell volume adaptation may be enhanced by cell-cell interactions.

Summary: GPCR autoantibodies are significantly altered in non-ischaemic heart failure (HF), but they are poorly correlated or even inversely correlated with haemodynamic, metabolic, and functional markers of disease severity, myocardial histology, and myocardial mitochondrial efficiency. These observations do not suggest a specific cardio-pathogenic role of GPCR autoantibodies in non-ischaemic HF, and further investigations are needed before specific therapies targeting GPCR autoantibodies can be clinically tested.

Summary: SARS-CoV-2 infection induces a metabolic shift towards glycolysis in host cells, with the glycolysis inhibitor 2DG being developed for COVID-19 treatment. Enhanced levels of transketolase (TKT) in infected cells suggest a role for the non-oxidative PPP, supported by the TKT inhibitor BOT inhibiting SARS-CoV-2 replication and synergizing with 2DG. Metabolic drugs like BOT and 2DG may improve COVID-19 therapy outcomes by targeting both viral replication and immunopathology.

Summary: Despite more concomitant total arch replacements in the redo group, early mortality was comparable in both groups. AVSRR can be performed in redo cardiac surgery without compromising the early postoperative outcome. Careful patient assessment and selection are crucial when considering the David procedure for patients with a history of previous cardiac surgery.

Summary: Primary ciliary dyskinesia (PCD) is a rare genetic disorder that affects the function of motile cilia in the respiratory tract, leading to chronic inflammation and lung damage. Current treatment options for PCD are only symptomatic, highlighting the need for curative therapies. In this study, researchers developed an in vitro model using human induced pluripotent stem cells (hiPSC) to recapitulate the diseased phenotype of PCD at the molecular, structural, and functional levels.

Summary: Computer-based analysis of long-term ECG monitoring in animal models is a time-consuming process due to the need for manual supervision for accurate arrhythmia detection. This study investigated the performance and feasibility of three ECG interval analysis approaches in detecting ventricular arrhythmias. Results showed that the combined attribute and pattern recognition analysis approach had higher accuracy in classifying detected events and accurately depicting arrhythmia burden. Additionally, this approach significantly reduced working time compared to manual supervision. Therefore, it is a valuable method for cost-effective and time-efficient analysis of large preclinical ECG datasets.

Summary: Abnormalities during trophoblast development can lead to pregnancy-related complications, but the underlying mechanisms are established during the first trimester. Human pluripotent stem cell (hPSC) technology provides a renewable source of cells for studying these diseases. By optimizing the treatment protocol, we were able to generate trophoblast cells enriched for HLA-G(pos) EVT-like cells, which will aid in understanding placenta-related disorders and investigation of immune tolerance towards the fetus.
