Evaluating the effects of moonlight on the vertical flight profiles of three western palaearctic swifts.

Recent studies have suggested the presence of moonlight mediated behaviour in avian aerial insectivores, such as swifts. Here, we use the combined analysis of state-of-the-art activity logger data across three swift species, the common, pallid and alpine swifts, to quantify flight height and activity in responses to moonlight-driven crepuscular and nocturnal light conditions. Our results show a significant response in flight heights to moonlight illuminance for common and pallid swifts, i.

Segmental and global longitudinal strain differences between Kawasaki disease and multi-system inflammatory syndrome in children.

Background: Multi-system inflammatory syndrome in children and Kawasaki disease have overlapping clinical features but comparative echocardiographic studies are lacking.

Methods: We reviewed echocardiography findings of all multi-system inflammatory syndrome cases between 1st April and 31st July, 2020 and typical Kawasaki disease patients with coronary arteries abnormalities consecutively followed between 1st October, 2016 and June 30th, 2019.

Results: We included 40 multi-system inflammatory syndrome children (25 males, 62.

Echocardiographic Normal Reference Ranges for Non-invasive Myocardial Work Parameters in Pediatric Age: Results From an International Multi-Center Study.

Aims: This international multi-center study aimed to demonstrate the feasibility and reliability of non-invasive myocardial work (MW) parameters in the pediatric population, and to provide normal reference ranges for this useful echocardiographic tool in this specific subset of patients.

Methods And Results: In this retrospective multi-center study involving three pediatric laboratories, 150 healthy children and adolescents (mean age of 10.6 ± 4.

Abnormal myocardial work in children with Kawasaki disease.

Kawasaki disease (KD) can be associated with high morbidity and mortality due to coronary artery aneurysms formation and myocardial dysfunction. Aim of this study was to evaluate the diagnostic performance of non-invasive myocardial work in predicting subtle myocardial abnormalities in Kawasaki disease (KD) children with coronary dilatation (CADL). A total of 100 patients (age 8.

Pure Aortic Regurgitation in Pediatric Patients.

Aortic regurgitation (AR) continues to be an important cause of morbidity and mortality in pediatric patients. Although echocardiographic parameters are well established for the adults, there are no clear cut-off values for AR severity in children. Cardiac magnetic resonance (CMR) imaging is considered a "gold standard" for a quantitative evaluation of the AR, but it is not widely available.

Left Atrial Strain to Identify Diastolic Dysfunction in Children with Cardiomyopathies.

Background: Left ventricular (LV) diastolic dysfunction (DD) carries worse prognosis in childhood. 2-dimensional (2-D) left atrial (LA) strain accurately categorizes DD in adults but its role in children is unknown. Thus, the aim of this study is to investigate whether LA strain and strain rate could diagnose and classify DD in children with dilated (CMD), hypertrophic (HCM) and restrictive (RCM) cardiomyopathies (CM).

Left Ventricular Twist Mechanics to Identify Left Ventricular Noncompaction in Childhood.

Background: Left ventricular noncompaction cardiomyopathy (LVNC) is associated with poor clinical outcome in childhood. Standard diagnostic criteria are still controversial, especially in young patients. Recent studies in adults demonstrated that left ventricular (LV) twist is abnormal in LVNC, but it has not been investigated in pediatric patients to date.

Prognostic value of echocardiographic parameters in pediatric patients with Ebstein's anomaly.

Background: Accurate risk stratification of patients with Ebstein's anomaly (EA) is crucial. Aim of the study was to assess the prognostic value of echocardiography, including 2D speckle tracking (STE) derived myocardial deformation indices, for predicting outcome in pediatric and young adult unrepaired EA patients.

Methods: Fifty consecutive EA patients (1 day-18 years, 52% males) underwent echocardiography and were followed for a mean follow-up of 60 ± 41 months for clinical outcome (ventricular tachyarrhythmia, heart failure, need for surgery and/or death).
