Article Abstract
End-stage heart failure is a deadly disease. Current total artificial hearts (TAHs) carry high mortality and morbidity and offer low quality of life. To overcome current biocompatibility issues, we propose the concept of a soft robotic, hybrid (pumping power comes from soft robotics, innerlining from the patient's own cells) TAH. The device features a pneumatically driven actuator (septum) between two ventricles and is coated with supramolecular polymeric materials to promote anti-thrombotic and tissue engineering properties. In vitro, the Hybrid Heart pumps 5.7 L/min and mimics the native heart's adaptive function. Proof-of-concept studies in rats and an acute goat model demonstrate the Hybrid Heart's potential for clinical use and improved biocompatibility. This paper presents the first proof-of-concept of a soft, biocompatible TAH by providing a platform using soft robotics and tissue engineering to create new horizons in heart failure and transplantation medicine.

Introduction to the soft wearable sensors themed collection.

Soft wearable sensors offer promising potential for advanced diagnostics, therapeutics, and human-machine interfaces. Unlike conventional devices that are bulky and rigid, often compromising skin integrity, comfort, and user compliance, soft wearable sensors are flexible, conformable, and better suited to the dynamic skin surface. This improved mechanical integration enhances signal fidelity and device performance, while also enabling safer, more comfortable, and continuous physiological monitoring in real-world environments.

Robotic mitral repair is often associated with longer ischaemic and cardiopulmonary bypass times, particularly early in the learning curve. We demonstrate a semi-continuous, three-suture technique for robotic annuloplasty that retains the mechanical principles of traditional interrupted sutures while leveraging the advantages of robotic precision and exposure. The use of pre-knotted sutures minimizes intra-cardiac knot tying, further enhancing procedural efficiency.

G-quadruplexes (G4) are four-stranded nucleic acid structures formed within sequences containing repeated guanine tracts separated by intervening loop regions. Abundant in the human genome, they play crucial roles in transcription regulation and genome maintenance. Although theoretically capable to adopt 26 different folding topologies─primarily differing in loop arrangements─only 14 of these have been observed experimentally.

This study aims to systematically assess the therapeutic effectiveness of TiRobot-assisted percutaneous kyphoplasty or vertebroplasty in managing osteoporotic thoracolumbar compression fractures. Previous studies have suggested that TiRobot-assisted techniques outperform conventional manual procedures in treating this condition, but relevant conclusions remain controversial. A thorough literature retrieval was carried out across 4 major databases: PubMed, Embase, the Cochrane Library, and Web of Science.

Objectives: This study evaluated the effects of proximal core training on biomechanical risk factors and strength parameters in individuals at high risk of anterior cruciate ligament (ACL) injury (specifically: those exhibiting pathological movement patterns, neuromuscular deficits or biomechanical risk factors) and compared direct versus indirect interventions. We hypothesised that targeted training enhances dynamic knee stabilisation and hip control during high-risk manoeuvres, with direct approaches providing superior biomechanical benefits through neuromuscular control optimisation.
Design: Systematic review and meta-analysis using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach.
