Objective: To describe the 12-month mortality of Dutch COVID-19 intensive care unit patients, the total COVID-19 population and various subgroups on the basis of the number of comorbidities, age, sex, mechanical ventilation, and vasoactive medication use.

Methods: We included all patients admitted with COVID-19 between March 1, 2020, and March 29, 2022, from the Dutch National Intensive Care (NICE) database. The crude 12-month mortality rate is presented via Kaplan-Meier survival curves for each patient subgroup.

Article Synopsis
  • Most commercial laying hens experience keel bone damage, which includes deviations and fractures.
  • Researchers aimed to train a deep learning model to automatically segment the keel bone from x-ray images of hens.
  • The model demonstrated high accuracy in segmentation (Dice coefficients of 0.88-0.90), indicating its potential for automating the monitoring of keel bone health.
