Organoids grown from cholangiocytes – the epithelial cells of the bile duct – are poised to be used in ex vivo cell therapy to increase the number of donated livers that are suitable for transplant, and also for direct bile duct repairs. The organoids have been shown to be effective in correcting defects in mouse models and in perfused donated livers. They are now being tested in large animal models.

Researchers at the University of California San Diego (UCSD) have taken wearables to a new level with a soft skin patch that integrates functions currently siloed in continuous glucose monitors, wearables, wellness apps and hospital monitors. The all-in-one patch can be worn on the neck to continuously track blood pressure, heart rate, glucose, lactate, alcohol and caffeine.

Researchers at Thomas Jefferson University have implanted brain electrodes in a patient who suffered a subcortical ischemic stroke more than a year ago to help them overcome abnormal muscle tone and control a robotic arm brace. Artificial intelligence (AI) algorithms interpret neuronal signals recorded by the electrodes into movement of the brace.

As of the end of January, SARS-CoV-2 has demonstrably infected more than 100 million individuals globally. It has killed more than 2 million. And the long-term sequelae of COVID infections – to say nothing of the health consequences of grief, social isolation and widespread economic distress – are still unfolding and will be for years to come.
