Cardiac implantable electronic devices (CIEDs) generate substantial data, often stored in image or PDF formats. Remote monitoring, now an integral component of patient care, places considerable administrative burdens on clinicians and staff, in large part due to the challenge of integrating these data seamlessly into electronic health records. Since 2006, the Heart Rhythm Society, in collaboration with the CIED industry, has led an initiative to establish a unified standard nomenclature.

- Adenoid cystic carcinomas (AdCC) of salivary gland origin are primarily defined by the presence of specific gene fusions, notably MYB::NFIB and MYBL1::NFIB, with sinonasal AdCC being particularly aggressive and lacking effective treatments.
- Researchers conducted an extensive analysis of 88 sinonasal AdCC cases using various techniques like NGS and FISH to identify gene fusions and mutations, finding that the majority harbored canonical fusions while some had noncanonical ones, with a few tumors showing no fusions at all.
- Mutational analysis revealed that about 68% of AdCCs tested (21 out of 31) had mutations in key oncogenes, highlighting potential areas for targeted
The development of computational models for the prediction of cardiac cellular dynamics remains a challenge due to the lack of first-principled mathematical models. We develop a novel machine-learning approach hybridizing physics simulation and graph networks to deliver robust predictions of cardiomyocyte dynamics. Embedded with inductive physical priors, the proposed constraint-based interaction neural projection (CINP) algorithm can uncover hidden physical constraints from sparse image data on a small set of beating cardiac cells and provide robust predictions for heterogenous large-scale cell sets.

- Lipid-containing vacuoles in microglia have been associated with neurodegenerative disorders for over a century, and recent studies show altered lipid metabolism in these conditions.
- Research focused on how lipid-enriched nanoparticles affect microglia, revealing that these nanoparticles lead to vacuolization and the formation of Gitterzellen, a distinct microglia phenotype seen in Alzheimer's disease.
- The study suggests that lipid-nanoparticles trigger this process through specific pathways, providing a valuable in vitro model to investigate the long-term effects of neurodegeneration.
