Heart failure has been recognized as a major public health problem. Its incidence and prevalence is increasing and imposes substantial burden on the health care system. Despite much progress in development of many new drugs and innovations in palliative surgical strategy, nontransplant cardiac surgical procedures and the use of mechanical assist devices, pediatric heart transplantation remains the best treatment option for patients with end-stage heart failure. So far, more than 6000 pediatric heart transplantations have been performed worldwide. This article reviews some clinical aspects of pediatric heart transplantation, including the history, indications and contraindications, donor evaluation and recipient management, surgical techniques, risk factors of mortality, and survival of pediatric heart transplantation. The short- and long-term outcomes of pediatric heart transplantation are encouraging. However, the lack of donor hearts still hampers its clinical application.

Background: The precise pathways connecting insulin resistance (IR) to atherosclerotic cardiovascular disease (ASCVD) remain undefined. The present study aimed to examine the mediating role of arterial stiffness in the association between IR and ASCVD, providing epidemiology insights into the potential mechanisms driving IR to incident ASCVD.
Methods: A total of 59,777 participants from the Kailuan Study Arterial Stiffness Subcohort who were free of ASCVD at baseline were enrolled in the present study.

To regulate brain function, peripheral compounds must traverse the blood-brain barrier (BBB), an interface between the brain and the circulatory system. To determine whether specific transport mechanisms are relevant for sleep, we conducted a BBB-specific inducible RNAi knockdown (iKD) screen for genes affecting sleep in . We observed reduced sleep with knockdown of solute carrier , a carnitine transporter, as determined by isotope flux.

E-point septal separation (EPSS) and tricuspid annular plane systolic excursion (TAPSE) are M-mode measures of left and right ventricular systolic function, with limited pediatric point-of-care ultrasound (POCUS) research. We conducted a cross-sectional study in a pediatric emergency department, enrolling 12-17-year-olds without cardiopulmonary complaints. Exclusion criteria included abnormal vital signs, fever, altered mental status, or psychiatric illness.

Objectives: Small studies of extracorporeal membrane oxygenation (ECMO) support for children with refractory septic shock (RSS) suggest that high-flow (≥ 150 mL/kg/min) venoarterial ECMO and a central cannulation strategy may be associated with lower odds of mortality. We therefore aimed to examine a large, international dataset of venoarterial ECMO patients for pediatric sepsis to identify outcomes associated with flow and cannulation site.
Design: Retrospective analysis of the Extracorporeal Life Support Organization (ELSO) database from January 1, 2000, to December 31, 2021.

: Cause of death analysis is fundamental to forensic pathology. We present the case of a 9½-year-old girl with a genetically confirmed diagnosis of Dravet syndrome who died in her sleep with no evidence of motor seizure. She also had a lifelong history of recurrent pneumonias and, along with her family, had tested positive for COVID-19 10 days before death.
