Appraisal of partial anomalous pulmonary venous drainage through a lumped-parameter mathematical model: a new pathophysiological proof of concept.

Objectives: Haemodynamic determinants of the ratio between pulmonary and systemic flow (Qp/Qs) in partial anomalous pulmonary venous return (PAPVR) are still not fully understood. Indeed, among patients with the same number of lung segments draining anomalously, a great variability is observed in terms of right ventricular overload. The aim of this study was to test the hypothesis that the anatomic site of drainage, affecting the total circuit impedance, independently influences the magnitude of shunt estimated by Qp/Qs.

Awareness of cholesterol levels in 46,309 Italian children and adolescents unveils the tip of the iceberg.

Background And Aims: Cardiovascular diseases (CVD) risk factors include high cholesterol. Children with total cholesterol (TC) levels ≥ 170 mg/dL are usually considered hypercholesterolemic. This study aimed at investigating the awareness of TC levels in a large Italian paediatric population and at looking for a possible correlation between their TC and TC in their parents' blood.

Pediatric Hypertension: A Condition That Matters.

Systemic hypertension has been considered mainly as an adult health issue for a long time, but it is now being increasingly acknowledged as a significant problem also among pediatric patients. The frequency of pediatric hypertension has grown mostly because of increases in childhood obesity and sedentary lifestyles, but secondary forms of hypertension play a role as well. Considering that unaddressed hypertension during childhood can result in enduring cardiovascular complications, timely identification and intervention are essential.
