Orthotopic substitution of the bladder in females is a procedure which is increasing worldwide. Patients with tumours of the bladder neck or the trigon, or with multifocal tumours, expanded carcinomas in situ or massive pelvic adenopathies are not eligible for the procedure. The main consideration should be the risk of urinary incontinence or hypercontinence. Our experience relates to 8 patients, the neobladder being constructed using the Studer technique. Six months postoperatively daytime continence was 100% and night-time continence 75%.

Transcatheter Tricuspid Valve Replacement: Current Options and Future Perspectives.
Rev Cardiovasc Med

Cardiovascular Department IRCCS (Istituto di Ricerca e Cura a Carattere Scientifico) Humanitas Research Hospital, 20089 Rozzano, Milan, Italy.
Tricuspid regurgitation (TR) is a potentially lethal condition and represents a significant clinical challenge both for clinical and interventional cardiologists. Traditionally managed medically and surgically, transcatheter therapies are now an emerging option, especially in patients with prohibitive surgical risk due to age or comorbidities. Transcatheter tricuspid valve replacement (TTVR) is emerging as a potential solution for patients suffering from TR with positive clinical data supporting its use in a wide range of anatomies and clinical settings.

Purpose Of Review: We describe the evolution of caval valve implantation (CAVI) as a treatment for severe symptomatic tricuspid regurgitation (TR) in the high surgical risk patient.
Recent Findings: Surgical treatment of severe TR is often limited by the high surgical risk of the patients who tend to develop severe secondary TR. Coaptation, annuloplasty, and orthotopic replacement strategies are all limited by annular and leaflet geometry, prior valve repair, and the presence of cardiac implantable device leads.
Manganese Galvanic Cells Intervene in Tumor Metabolism to Reinforce cGAS-STING Activation for Bidirectional Synergistic Hydrogen-Immunotherapy.

The cGAS-STING pathway is pivotal in initiating antitumor immunity. However, tumor metabolism, particularly glycolysis, negatively regulates the activation of the cGAS-STING pathway. Herein, Mn galvanic cells (MnG) are prepared via liquid-phase exfoliation and in situ galvanic replacement to modulate tumor metabolism, thereby enhancing cGAS-STING activation for bidirectional synergistic H-immunotherapy.

Polymer heart valves are a promising alternative to bioprostheses, the use of which is limited by the risks of calcific deterioration of devitalized preserved animal tissues. This is especially relevant in connection with the increasingly widespread use of transcatheter valves. Advances in modern organic chemistry provide a wide range of polymers that can replace biological material in the production of valve prostheses.

Article Synopsis
- Tricuspid regurgitation (TR) is a common issue after heart transplantation, and a new treatment called transcatheter tricuspid valve replacement (TTVR) has emerged, although it comes with risks.
- A 46-year-old woman who underwent a heart transplant developed severe TR, had a TTVR procedure, but later suffered from cardiogenic shock and sudden cardiac death, linked to complications in the area of her heart's electrical conduction system.
- This case highlights the dangers of TTVR in heart transplant patients, emphasizing the need for close monitoring due to the potential for serious heart rhythm issues like complete heart block.
