Low-dose dobutamine stress myocardial contrast echocardiography for evaluating myocardial microcirculation perfusion and predicting long-term prognosis in ST-segment elevation myocardial infarction after percutaneous coronary intervention.

Objective: Percutaneous coronary intervention (PCI) can effectively restore myocardial perfusion in patients with ST-segment elevation myocardial infarction (STEMI). Nevertheless, STEMI patients may still experience a "no-reflow" phenomenon after PCI. Accordingly, this study focused on the clinical value of low-dose dobutamine stress myocardial contrast echocardiography (MCE) for evaluating myocardial microcirculation perfusion and long-term prognosis in STEMI patients after PCI.

Generation of three-dimensional meat-like tissue from stable pig epiblast stem cells.

Cultured meat production has emerged as a breakthrough technology for the global food industry with the potential to reduce challenges associated with environmental sustainability, global public health, animal welfare, and competition for food between humans and animals. The muscle stem cell lines currently used for cultured meat cannot be passaged in vitro for extended periods of time. Here, we develop a directional differentiation system of porcine pre-gastrulation epiblast stem cells (pgEpiSCs) with stable cellular features and achieve serum-free myogenic differentiation of the pgEpiSCs.

Lifestyles, Left Atrial Structure and Function, and Cognitive Decline in Adults with Metabolic Syndrome.

Evidence supports associations of lifestyle (including diet and physical activity) and weight with cognitive functioning, but the pathways responsible for these associations have not been fully elucidated. Because healthier lifestyles have been associated with better left atrial structure and function, which in turn is associated with better cognitive functioning, we tested the hypothesis that left atrial structure and function is a potential mediator of the association between lifestyle and cognition. We included 476 participants classed as overweight or obese with metabolic syndrome from three centers in Spain.

Lifestyles, left atrial structure and function, and cognitive decline in adults with the metabolic syndrome.

Evidence supports associations of lifestyle-including diet and physical activity-and weight with cognitive functioning, but the pathways responsible for these associations have not been fully elucidated. Because healthier lifestyles have been associated with better left atrial structure and function, which in turn is associated with better cognitive functioning, we tested the hypothesis that left atrial structure and function is a potential mediator of the association between lifestyles and cognition. We included 476 participants with overweight or obesity and metabolic syndrome from three centers in Spain who underwent lifestyle assessment and transthoracic echocardiography at baseline and had repeated measurements of the Trail Making A test, a measure of executive function, at baseline and at the two-year follow-up.

Gellan gum-gelatin scaffolds with Ca crosslinking for constructing a structured cell cultured meat model.

Therefore, determining the effect of lifestyle interventions on blood concentrations of biomarkers of AF-related pathways could help understand AF pathophysiology and contribute to AF prevention.

Physician Empathy in Doctor-Patient Communication: A Systematic Review.

Physician empathy is at the heart of doctor-patient communication and significantly influences patient outcomes. However, the research on how physicians express their empathy and how physician empathy affects patient outcomes and doctor-patient communication has not been well summarized in the latest literature. Thus, we conducted a systematic review to synthesize existing studies on physician empathy and its value to patient outcomes and doctor-patient communication.

Circulating Magnesium and Risk of Major Adverse Cardiac Events among Patients with Atrial Fibrillation in the ARIC Cohort.
