Background: Patients with chronic heart failure (HF) are often rehospitalized; rehospitalization identifies subjects with a poorer quality of life and a worse prognosis. Estimates of the time intervals by tissue Doppler imaging (TDI) in patients with chronic HF has not been fully investigated, despite recent studies having explored the prognostic role of TDI-derived parameters in major cardiac diseases, such as HF. We, therefore, aimed to assess the prognostic value of time intervals evaluated by TDI in patients with chronic HF.
Methods: A total of 249 patients with chronic HF enrolled in the Daunia Heart Failure Registry underwent echocardiography assessment and were followed prospectively for a mean 284 ± 210 days. Conventional echocardiography and TDI parameters were calculated; time intervals were calculated by TDI: ST (systolic time), ET (ejection time), FT (filling time), and ICT (isovolumic contraction time). We also have calculated ICT/ET and tissue myocardial performance index ([ICT+IRT]/ET).
Results: At univariate analysis, ET (RR: 0.80, 95% confidence interval [CI] 0.71-0.90, P < 0.001), ST (RR: 0.88, 95% CI 0.78-0.99, P < 0.05), FT (RR: 0.88, 95% CI 0.78-0.99, P < 0.05), ICT/ET (RR: 1.21, 95% CI 1.07-1.37, P < 0.01) were related to the occurrence of rehospitalization during follow-up. At multivariate Cox regression analysis, correlations remained significant for ET and ST (P < 0.05 and P < 0.01, respectively).
Conclusions: Time intervals assessed by TDI may be helpful in predicting the risk of rehospitalization in subjects with chronic HF.

Objective: The objective of this systematic review and meta-analysis is to clarify the rehabilitation efficacy of virtual reality (VR) balance training after anterior cruciate ligament reconstruction (ACLR).
Methods: This meta-analysis was registered in PROSPERO with the registration number CRD42024520383. The electronic databases PubMed, Web of Science, Cochrane Library, MEDLINE, Embase, China National Knowledge Infrastructure, Chinese Biomedical Literature, China Science and Technology Journal Database, and Wanfang Digital Periodical database were systematically searched to identify eligible studies from their inception up to January 2024.

The brain can remarkably adapt its decision-making process to suit the dynamic environment and diverse aims and demands. The brain's flexibility can be classified into three categories: flexibility in choosing solutions, decision policies, and actions. We employ two experiments to explore flexibility in decision policy: a visual object categorization task and an auditory object categorization task.

Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).
