Background: Evidence regarding the incidence of prosthesis-patient mismatch (PPM) and long-term mortality after transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is scarce.

Objectives: This study sought to assess the incidence and prognostic impact of PPM after TAVR for bicuspid AS compared with that for tricuspid AS.

Methods: In total, 7,393 patients who underwent TAVR were prospectively enrolled in the OCEAN-TAVI (Optimized Catheter Valvular Intervention Transcatheter Aortic Valve Implantation) registry, an ongoing Japanese, multicenter registry.

One-year hemodynamic and clinical outcomes in self-expanding valves: Comparison of ACURATE neo2 versus ACURATE neo.

Background/purpose: Transcatheter aortic valve replacement (TAVR) with ACURATE neo2 showed better hemodynamic outcomes by mitigating paravalvular leakage (PVL) compared with ACURATE neo, and revealed promising one-year outcomes in single-arm studies. However, studies comparing the hemodynamic and clinical outcomes of the two valves are still scarce. Therefore, this study aimed to compare the one-year hemodynamic and clinical outcomes between the neo2 and neo.

Combining EGFR and KRAS G12C Inhibitors for KRAS G12C Mutated Advanced Colorectal Cancer.

KRAS is a commonly mutated gene in advanced colorectal cancer (CRC). Recently, inhibitors of KRAS G12C were developed and have shown promising efficacy for KRAS G12C mutated non-small cell lung cancer. However, KRAS G12C inhibitor monotherapy has not demonstrated excellent efficacy for KRAS G12C mutated advanced CRC due to multiple resistance mechanisms, especially receptor tyrosine kinase (RTK) signaling activation.

Eleven new glycosidic acid methyl esters from the crude resin glycoside fraction of Ipomoea alba seeds.

Resin glycosides are characteristic of plants of the Convolvulaceae family and are well-known purgative ingredients in crude drugs, such as Rhizoma Jalapae, Orizaba Jalapa Tuber, and Pharbitidis Semen, which are used in traditional medicine and derived from plants belonging to this family. Isolated resin glycosides have demonstrated diverse biological activities, including antibacterial, ionophoric, anti-inflammatory, antiviral, and multidrug-resistance-modulating properties, as well as cytotoxicity against cancer cells. These compounds consist of hydroxyl fatty acid oligoglycosides (glycosidic acids), with portions of the saccharide moieties acylated with some organic acids to form the core structure.

KRAS G12C inhibitor combination therapies: current evidence and challenge.

Although KRAS G12C inhibitors have proven that KRAS is a "druggable" target of cancer, KRAS G12C inhibitor monotherapies have demonstrated limited clinical efficacy due to primary and acquired resistance mechanisms. Multiple combinations of KRAS G12C inhibitors with other targeted therapies, such as RTK, SHP2, and MEK inhibitors, have been investigated in clinical trials to overcome the resistance. They have demonstrated promising efficacy especially by combining KRAS G12C and EGFR inhibitors for KRAS G12C-mutated colorectal cancer.
