Utility of the 6-Min Walk Test for Assessing Physical Performance in Pediatric Heart Transplant Recipients.

Background: Physical performance capacity (PPC) of pediatric heart transplant (HT) recipients is reportedly low to normal, and longitudinal follow-up of these patients is recommended. However, no recommendation for a follow-up method is available. In this study, the correlation between the 6-min walk test (6MWT), various clinical parameters, and a physical performance test set was evaluated to develop a simple follow-up tool for PPC.

Lymphatic Disorder Management in Pediatric Patients With Congenital Heart Disease in European Pediatric Cardiology Centers: Current Status, Disparities, and Future Considerations.

Background: Lymphatic disorders such as protein-losing enteropathy, plastic bronchitis, and chylothorax are important complications of the Fontan circulation and ultimately result in an increased risk of early death. Several European centers are now performing lymphatic procedures. The aim of this study is to map the extent of these lymphatic disorders and treatments provided across European pediatric cardiology centers.

Improving performance in colorectal cancer histology decomposition using deep and ensemble machine learning.

In routine colorectal cancer management, histologic samples stained with hematoxylin and eosin are commonly used. Nonetheless, their potential for defining objective biomarkers for patient stratification and treatment selection is still being explored. The current gold standard relies on expensive and time-consuming genetic tests.

Noninvasive Hemodynamic Assessment for Late-Stage Truncus Arteriosus Management.

A 7-year-old girl with unoperated truncus arteriosus arrived in Finland as a refugee. In contrast to our previous practices, hemodynamic assessment was made using cardiovascular magnetic resonance instead of cardiac catheterization. During the 2-year follow-up period, the right ventricular pressure was estimated to be 50% of systemic pressure in echocardiogram evaluations.

Estimating the Workability of Concrete with a Stereovision Camera during Mixing.

The correct workability of concrete is an essential parameter for its placement and compaction. However, an absence of automatic and transparent measurement methods to estimate the workability of concrete hinders the adaptation from laborious traditional methods such as the slump test. In this paper, we developed a machine-learning framework for estimating the slump class of concrete in the mixer using a stereovision camera.
