Age-Based Classification and Outcomes in Pediatric Heart Failure: Findings From a Retrospective Multicenter Cohort Study.

Background: Although heart failure is a well-known major global public health concern, the general understanding of the clinical status of pediatric heart failure (PHF) is inadequate. Therefore, this study aims to enhance the general understanding of clinical characteristics across different PHF age groups and provide references for improving PHF treatment strategies.

Methods: This multicenter retrospective cohort study involved patients from 20 Chinese provinces, primarily including hospitalized patients (aged ≤18 years) diagnosed with heart failure between January 2013 and December 2022.

[Research progress on the diagnosis of pediatric heart failure].

Heart failure is a complex clinical syndrome and pediatric heart failure (PHF) has a high mortality rate. Early diagnosis is crucial for treatment and management of PHF. In clinical practice, various tests and examinations play a key role in the diagnosis of PHF, including continuously updated biomarkers, echocardiography, and cardiac magnetic resonance imaging.

Intelligent Optimization and Impact Analysis of Energy Efficiency and Carbon Reduction in the High-Temperature Sintered Ore Production Process.

The coordinated optimization of energy conservation, efficiency improvement, and pollution reduction in the sintering production process is vital for the efficient and sustainable development of the sintering department. However, previous studies have shown shortcomings in the multi-objective collaborative optimization of sintering systems and the quantification of pollutant impacts. To address these, this paper proposes a multi-objective optimization method integrated with the NSGA-III algorithm and establishes an integrated system optimization model for sintered ore production and high-temperature waste heat recovery.

Multi-process production occurs in the iron and steel industry, supporting 'dual carbon' target: An in-depth study of CO emissions from different processes.

Reducing CO emissions of the iron and steel industry, a typical heavy CO-emitting sector, is the only way that must be passed to achieve the 'dual-carbon' goal, especially in China. In previous studies, however, it is still unknown what is the difference between blast furnace-basic oxygen furnace (BF-BOF), scrap-electric furnace (scrap-EF) and hydrogen metallurgy process. The quantitative research on the key factors affecting CO emissions is insufficient.

Muti-objective optimization on energy consumption, CO emission and production cost for iron and steel industry.

Due to high material density, high energy consumption density and CO emission density, it is not only difficult but significant to clarify the relationship between energy consumption, the CO emission and the production cost in different conditions. However, the previous researches rarely refer how to balance the energy consumption, the CO emission and the production cost after the fluctuation of material, energy and carbon price as well as what will happen to them if production structure changes. Therefore, based on the conservation law of mass and energy, to study iron and steel manufacturing process (ISMP), this paper, taking carbon price into consideration, establishes a muti-optimization model of energy consumption, CO emission and cost.

Health-related quality of life in children with congenital heart disease following interventional closure versus minimally invasive closure.

Introduction: The presence of atrial septal defect (ASD) or ventricular septal defect (VSD) significantly affects children's quality of life and, if not treated adequately, can contribute to increased mortality. In this study, we evaluated and compared the health-related quality of life (HRQL) of children who underwent treatment using either minimally invasive closure (MIC) or interventional closure (IC).

Materials And Methods: In this observational and comparative study 199 children (2 to 4.

Oxidative Phosphorylation-Mediated E-Selectin Upregulation Is Associated With Endothelia-Monocyte Adhesion in Human Coronary Artery Endothelial Cells Treated With Sera From Patients With Kawasaki Disease.

E-selectin is a cell adhesion molecule of the vascular endothelium that mediates leukocyte rolling in the early inflammatory responses in many diseases including Kawasaki disease (KD). Previous studies have demonstrated that the expression levels of E-selectin was significantly increased in the sera of KD patients and in endothelial cells of KD patient's autopsy. In this study, we aimed to examine E-selectin levels in endothelial cells treated with sera from KD patients and explore the underlying mechanisms.

An evaluation of greenhouse gas emission efficiency in China's industry based on SFA.

As one of the largest countries with sound industrial systems in the world, China is a major emitter of greenhouse gases. In order to achieve sustainable development, the analysis of greenhouse gas emissions from industry is of great significance. This research evaluates the greenhouse gas emission efficiency (GHG efficiency) at industry level in 26 sectors of China and analyzes the impacts of its determinants using stochastic frontier approach.
