Kidney Outcomes in Children Receiving Extracorporeal Membrane Oxygenation: A Single-Center Acute Cohort From 2009 to 2019, Followed to 2021.

Objectives: Long-term kidney outcomes after extracorporeal membrane oxygenation (ECMO) are little quantified and understood. We aimed to describe the frequency of kidney dysfunction screening during follow-up and the prevalence of long-term kidney disease.

Design: Retrospective cohort of pediatric ECMO patients with estimated glomerular filtration rate (eGFR) (mL/min/1.

Characterization of arteriosclerosis based on computer-aided measurements of intra-arterial thickness.

Purpose: Our purpose is to develop a computer vision approach to quantify intra-arterial thickness on digital pathology images of kidney biopsies as a computational biomarker of arteriosclerosis.

Approach: The severity of the arteriosclerosis was scored (0 to 3) in 753 arteries from 33 trichrome-stained whole slide images (WSIs) of kidney biopsies, and the outer contours of the media, intima, and lumen were manually delineated by a renal pathologist. We then developed a multi-class deep learning (DL) framework for segmenting the different intra-arterial compartments (training dataset: 648 arteries from 24 WSIs; testing dataset: 105 arteries from 9 WSIs).
