BACKGROUND: Only few studies have investigated the effect of topical application of tranexamic acid (TXA) on "minimally" invasive joint surgical procedures in which articular cartilage is preserved; for this reason, actually many surgeons avoid the use of topical TXA even if the disadvantage related to a blood loss can occur. The aim of this study was to evaluate the cytotoxicity, on human chondrocytes, of TXA at different concentrations and times of exposure and the mechanisms of cell death...

PURPOSE: Cognitive impairment and reduced quality of life is a common condition in patients with heart failure (HF). Percutaneous mitral valve repair using (PMVR) MitraClip (MC) has emerged as a promising interventional tool, reducing all-cause mortality and hospitalization as well as increasing cognitive functioning and quality of life. However, the benefit of HF patients with severely depressed cognitive functioning remains unknown. METHODS: We assessed cognitive functioning (figural memory-FGT, executive function-TOL, TMT B), psychosocial functioning (depression-PHQ-9, quality of life-SF36), and clinical parameters (echocardiography, 6-min walk test distance, and cardiac biomarkers) 1 day before (t0) and 6 weeks after (t1) MC intervention in HF patients (n = 40)...
