Atrial Secondary Tricuspid Regurgitation: Insights Into the EuroTR Registry.

Article Synopsis
- Atrial secondary tricuspid regurgitation (A-STR) is a subtype of secondary tricuspid regurgitation (STR) that is often treated with transcatheter tricuspid valve edge-to-edge repair (T-TEER), showing distinct patient characteristics and treatment outcomes.
- A study involving 641 patients revealed that 31% had A-STR, which was linked to better heart function, a higher presence of atrial fibrillation, and more effective TR reduction post-procedure compared to nonatrial STR patients.
- A-STR patients experienced improved survival rates and lower symptomatic burdens after treatment; only 38% remained symptomatic (NYHA class ≥III) after 2 years, compared to 46
Article Synopsis
- - The study focuses on the glycoprotein clusterin (CLU), which is important for cell growth and repairing DNA, and its effects on human astrocytic cell lines, showing that suppressing CLU leads to decreased cell growth and increased DNA damage response.
- - Researchers found that reducing CLU levels caused oxidative stress and triggered cellular aging (senescence) in astrocytoma cells and normal astrocytes, impacting mitochondrial function and altering energy production markers.
- - The findings highlight the crucial role of CLU in maintaining the cell cycle in astrocytes, suggesting that targeting CLU could be a promising strategy for treating gliomas (a type of brain tumor).
Amyloid β42 (Aβ42) plays a decisive role in the pathology of Alzheimer's disease. The Aβ42 peptide can aggregate into various supramolecular structures, with oligomers being the most toxic form. However, different Aβ species that cause different effects have been described.

However, long-term outcome data after M-TEER under real-world conditions are lacking.
Objectives: This study sought to assess long-term efficacy and survival after M-TEER in a large real-world registry.
The guidelines for clinical practice for carriers of pathogenic variants in clinically relevant genes predisposing to Lynch syndrome and colorectal cancer define the steps of primary and secondary prevention that should be provided to the individuals at high risk of developing hereditary cancer in the Czech Republic. The drafting of the guidelines was organized by the Oncogenetics Working Group of the Society for Medical Genetics and Genomics of J. E.
