Hypothesis: To demonstrate that a virtual reality (VR) simulation training program reduces heart rate variability during an assessment of surgical trainees' technical skills in arthroscopy.
Study Design: Prospective observational matched study.
Materials & Methods: Thirty-six orthopaedic surgery residents, new to arthroscopy, received standard training in arthroscopic knee surgery, supplemented by additional monthly training for 6months on a VR simulator for 16 of them. At inclusion, the 2 groups (VR and NON-VR) answered a questionnaire and performed a meniscectomy on a VR simulator. After 6months of training, two independent trainers blinded to the inclusion arms evaluated the technical skills of the two groups during meniscectomies on a model and on an anatomical subject. Heart rate variability (HRV) was measured using a wireless heart rate monitor during baseline, VR training, and assessment.
Results: After removing incomplete data, the analysis focused on 10 VR residents matched at inclusion with 10 NON-VR residents. The VR group had a significantly lower heart rate at the final assessment (p=0.02) and lower overall HRV (p=0.05). The low/high frequency ratio (LF/HF) was not significantly different between the groups (1.84 vs 2.05, p=0.66) but the before-after training comparison showed a greater decrease in this ratio in the VR group compared to the NON-VR group -0.76 (-41%) vs -0.08 (-4%).
Conclusion: This study demonstrates a significant difference in heart rate variability between trained residents versus untrained residents during the final assessment of their technical skills at 6months. It appears that improving stress management should be an integral part of training programs in arthroscopic surgery.
Clinical Interest: VR simulators in arthroscopy could improve non-technical skills such as heart rate variability, from the perspective of accountability.
Level Of Evidence: III.

In lung CT imaging, motion artifacts caused by cardiac motion and respiration are common. Recently, CLEAR Motion, a deep learning-based reconstruction method that applies motion correction technology, has been developed. This study aims to quantitatively evaluate the clinical usefulness of CLEAR Motion.

Objective: To prepare astragaloside IV dripping pills (ASDP) and assess their therapeutic effects on mice with doxorubicin hydrochloride-induced dilated cardiomyopathy (DCM).: Astragaloside IV (AS) exhibits pharmacological effects in treating cardiovascular diseases, however, its clinical application is hindered by poor solubility and low bioavailability. The study sheds light on new therapeutic strategy of DCM and development of AS formulations.

Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.
Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.

Sepsis remains a leading cause of critical illness and mortality worldwide, driven by a dysregulated host response to infection and often complicated by persistent tachycardia and cardiovascular dysfunction. Increasing evidence implicates excessive sympathetic activation as a contributor to sepsis-related hemodynamic instability and myocardial injury, prompting growing interest in the use of β-adrenergic blockade as a therapeutic adjunct. This review synthesizes current data on the safety and efficacy of short-acting, cardioselective β-blockers (BBs), particularly esmolol and landiolol, in septic shock.
