Didactic education in paediatric cardiology during the COVID-19 pandemic: a national fellow survey.

The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on medical educational curricula. We aimed to examine the impact of these unprecedented changes on the formal education of paediatric cardiology fellows through a nationwide survey. A REDCap™-based voluntary anonymous survey was sent to all current paediatric cardiology fellows in the United States of America in May, 2020. Of 143 respondents, 121 were categorical fellows, representing over one-fourth of all categorical paediatric cardiology fellows in the United States of America. Nearly all (140/143, 97.9%) respondents utilised online learning during the pandemic, with 134 (93.7%) reporting an increase in use compared to pre-pandemic. The percentage of respondents reporting curriculum supplementation with outside lectures increased from 11.9 to 88.8% during the pandemic. Respondents considered online learning to be "equally or more effective" than in-person lectures in convenience (133/142, 93.7%), improving fellow attendance (132/142, 93.0%), improving non-fellow attendance (126/143, 88.1%), and meeting individual learning needs (101/143, 70.6%). The pandemic positively affected the lecture curriculum of 83 respondents (58.0%), with 35 (24.5%) reporting no change and 25 (17.5%) reporting a negative effect. A positive effect was most noted by those whose programmes utilised supplemental outside lectures (62.2 versus 25.0%, p = 0.004) and those whose lecture frequency did not decrease (65.1 versus 5.9%, p < 0.001). Restrictions imposed by the COVID-19 pandemic have greatly increased utilisation of online learning platforms by medical training programmes. This survey reveals that an online lecture curriculum, despite inherent obstacles, offers advantages that may mitigate some negative consequences of the pandemic on fellowship education.

Advances in the Prenatal Management of Fetal Cardiac Disease.

Advances in the field have improved the prenatal management of cardiovascular diseases over the past few decades; however, there remains considerable challenges in the approach towards patient selection as well as the applicability of available therapies. This review aims to discuss the current knowledge, outcomes and challenges for prenatal intervention for congenital heart disease.

Assessment of Microvascular Function in Children and Adolescents with Diabetes and Obesity.

BACKGROUND: Endothelial dysfunction (ED) is a marker of vascular damage. Glycated hemoglobin (A1C) predicts vascular complications. The EndoPAT (peripheral arterial tonometry) device calculates the reactive hyperemic index (RHI), a measure of endothelial function. The greater the vasodilation, the higher the RHI. We hypothesized that children with poorly-controlled diabetes mellitus (DM) and non-diabetes mellitus (NDM) obese children have ED. METHODS: A cross-sectional study using the EndoPAT device was performed on children with poorly-controlled DM and NDM children. ANOVA, t-test, Mann-Whitney U test, multiple linear regression and Spearman correlation were used. RESULTS: Of 58 children that completed the study (aged 13.1 ± 3.42 years), 33 with type 1 diabetes (T1DM), 8 with type 2 diabetes (T2DM) and 17 were NDM obese children. Eighty-five percent were African-American, 60% were female and 79% entered puberty. The RHI of children with DM (1.42 ± 0.48) versus NDM obese group (1.40 ± 0.34) was not different (P = 0.86) regardless of the type of DM or body mass index. In the DM group, for every 1% increase in latest A1C, the RHI decreased by 0.097 (P = 0.01) after adjusting for age, gender, and type of DM. The RHI of DM patients with latest A1C of < 10% (1.70 ± 0.58) versus those with A1C ≥10% (1.21 ± 0.19) was statistically different (P = 0.02). In the total study population, males had significantly lower RHI (1.28 ± 0.36) when compared to females (1.51 ± 0.46), P = 0.04 but this difference disappeared when considering pubertal status and type of diabetes. CONCLUSIONS: Our data showed that patients with poorly-controlled DM as reflected by latest A1C of ≥ 10% had worse endothelial function as reflected by lower RHI score.

Cardiac Dysfunction and Shock in Pediatric Patients With COVID-19.

Coronavirus disease-2019 (COVID-19) has been reported to cause significant morbidity in adults, with reportedly a lesser impact on children. Cardiac dysfunction has only been described in adults thus far. We describe 3 cases of previously healthy children presenting with shock and COVID-19-related cardiac inflammation.
