Case Report: Allograft aortic valve replacement in irreparable infant mitral valve.

This case report describes a 3-month-old male infant diagnosed with severe mitral stenosis (MS) and mitral regurgitation (MR) by transthoracic echocardiography. The male infant initially underwent complex mitral valve repair surgery. However, postoperative deterioration occurred with hemodynamic instability and shock, necessitating multiple resuscitation efforts and ultimately requiring support from Extracorporeal Membrane Oxygenation (ECMO).

Effects and mechanisms of the myocardial microenvironment on cardiomyocyte proliferation and regeneration.

The adult mammalian cardiomyocyte has a limited capacity for self-renewal, which leads to the irreversible heart dysfunction and poses a significant threat to myocardial infarction patients. In the past decades, research efforts have been predominantly concentrated on the cardiomyocyte proliferation and heart regeneration. However, the heart is a complex organ that comprises not only cardiomyocytes but also numerous noncardiomyocyte cells, all playing integral roles in maintaining cardiac function.

An integrated analysis of Sacituzumab govitecan in relapsed or refractory metastatic triple-negative breast cancer.

Background: Sacituzumab govitecan (SG) is an antibody-drug conjugate that targets the human trophoblast cell-surface antigen 2 to deliver SN-38 to cancer cells. In this study, we assessed the efficacy and safety of SG in patients with relapsed or refractory metastatic triple-negative breast cancer (RM-TNBC).

Methods: For this integrated analysis, from inception to January 2, 2023, we searched PubMed, Web of Science, Embase, and Cochrane library databases for prospective studies that evaluated SC in RM-TNBC patients.
