Psychological intervention for knee osteoarthritis: a systematic review and meta-analysis.

This systematic review and meta-analysis aimed to evaluate the effectiveness of psychological interventions compared to standard rehabilitation in patients with knee osteoarthritis (OA). Given the recognized influence of psychological factors in OA management, the review assessed their impact on pain, functional disability, and self-efficacy. A comprehensive search was performed across multiple databases, including PubMed, PsycINFO, CINAHL, the Cochrane Central Register of Controlled Trials, Web of Science, OpenGrey, and ClinicalTrials.

Long-term impact of molecular epidemiology shifts of methicillin-resistant on severity and mortality of bloodstream infection.

A 2019 nationwide study in Japan revealed the predominant methicillin-resistant Staphylococcus aureus (MRSA) types in bloodstream infections (BSIs) to be sequence type (ST)8-carrying SCC type IV (ST8-MRSA-IV) and clonal complex 1-carrying SCC type IV (CC1-MRSA-IV). However, detailed patient characteristics and how these MRSA types evolve over time remain largely unknown. In this long-term single-center study, MRSA strains isolated from blood cultures at Nagasaki University Hospital from 2012 to 2019 were sequenced and analyzed.

Induction of cardiac alternans in human iPS-derived cardiomyocytes through β-adrenergic receptor stimulation.

Cardiac alternans (C-ALT) is a phenomenon of alternating strong and weak contractions in the heart and is considered a risk factor for the development of heart failure and arrhythmias. However, no model has been reported that can induce C-ALT in vitro using human cells, and the developmental mechanism of C-ALT has not been studied using human cells. In this study, we successfully induced C-ALT in vitro using human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs).
