Assessment of Epicardial Fat in Children: Its Role as a Cardiovascular Risk Factor and How It Is Influenced by Lifestyle Habits.

Epicardial adipose tissue (EAT) stands out as a distinctive repository of visceral fat, positioned in close anatomical and functional proximity to the heart. EAT has emerged as a distinctive reservoir of visceral fat, intricately interlinked with cardiovascular health, particularly within the domain of cardiovascular diseases (CVDs). The aim of our overview is to highlight the role of EAT as a marker for cardiovascular risk in children. We also explore the influence of unhealthy lifestyle habits as predisposing factors for the deposition of EAT. The literature data accentuate the consequential impact of lifestyle choices on EAT dynamics, with sedentary behavior and unwholesome dietary practices being contributory to a heightened cardiovascular risk. Lifestyle interventions with a multidisciplinary approach are therefore pivotal, involving a nutritionally balanced diet rich in polyunsaturated and monounsaturated fatty acids, regular engagement in aerobic exercise, and psychosocial support to effectively mitigate cardiovascular risks in children. Specific interventions, such as high-intensity intermittent training and circuit training, reveal favorable outcomes in diminishing the EAT volume and enhancing cardiometabolic health. Future clinical studies focusing on EAT in children are crucial for advancing our understanding and developing targeted strategies for cardiovascular risk management in this population.

Kawasaki disease: guidelines of the Italian Society of Pediatrics, part I - definition, epidemiology, etiopathogenesis, clinical expression and management of the acute phase.

The primary purpose of these practical guidelines related to Kawasaki disease (KD) is to contribute to prompt diagnosis and appropriate treatment on the basis of different specialists' contributions in the field. A set of 40 recommendations is provided, divided in two parts: the first describes the definition of KD, its epidemiology, etiopathogenetic hints, presentation, clinical course and general management, including treatment of the acute phase, through specific 23 recommendations.Their application is aimed at improving the rate of treatment with intravenous immunoglobulin and the overall potential development of coronary artery abnormalities in KD. Guidelines, however, should not be considered a norm that limits treatment options of pediatricians and practitioners, as treatment modalities other than those recommended may be required as a result of peculiar medical circumstances, patient's condition, and disease severity or complications.

Cost-effectiveness of neonatal ECG screening for the long QT syndrome.

AIMS: A significant number of preventable cardiac deaths in infancy and childhood are due to long QT syndrome (LQTS) and to unrecognized neonatal congenital heart diseases (CHDs). Both carry a serious risk for avoidable mortality and morbidity but effective treatments exist to prevent lethal arrhythmias or to allow early surgical correction before death or irreversible cardiac damage. As an electrocardiogram (ECG) allows recognition of LQTS and of some of the CHDs that have escaped medical diagnosis, and as LQTS also contributes to sudden infant death syndrome, we have analysed the cost-effectiveness of a nationwide programme of neonatal ECG screening. Our primary analysis focused on LQTS alone; a secondary analysis focused on the possibility of identifying some CHDs also. METHODS AND RESULTS: A decision analysis approach was used, building a decision tree for the strategies 'screening'-'no screening'. Markov processes were used to simulate the natural or clinical histories of the patients. To assess the impact of potential errors in the estimates of the model parameters, a Monte Carlo sensitivity analysis was performed by varying all baseline values by +/-30%. Incremental cost-effectiveness analysis for the primary analysis shows that with the screening programme, the cost per year of life saved is very low: 11,740 euro. The cost for saving one entire life of 70 years would be 820,000 euro. Even by varying model parameters by +/-30%, the cost per year of life saved remains between 7400 euro and 20,400 euro. These figures define 'highly cost-effective' screening programmes. The secondary analysis provides even more cost-effective results. CONCLUSION: A programme of neonatal ECG screening performed in a large European country is cost-effective. An ECG performed in the first month of life will allow the early identification of still asymptomatic infants with LQTS and also of infants with some correctable CHDs not recognized by routine neonatal examinations. Appropriate therapy will prevent unnecessary deaths in infants, children, and young adults.
