For the first time, scientists are able to directly compare the different kinds of injury that mechanical ventilation causes to cells in the lungs. Using a ventilator-on-a-chip model, researchers found shear stress from the collapse and reopening of air sacs is the most injurious type of damage.

Open-access article published in Lab on a Chip: [https://pubs.rsc.org/en/content/articlelanding/2024/lc/d4lc00143e](https://pubs.rsc.org/en/content/articlelanding/2024/lc/d4lc00143e)

This is why it’s beneficial to use PEEP on ventilators.

I’m sure it’s not keeping every single alveoli open so there’s still room for some amount of damage to occur

Cool study

I wonder if they can invent some kinda, lung-lube that they could add to the respirator air stream.

For the first time, scientists are able to directly compare the different kinds of injury that mechanical ventilation causes to cells in the lungs. Using a ventilator-on-a-chip model, researchers found shear stress from the collapse and reopening of air sacs is the most injurious type of damage.

Researchers design a barnacle-inspired synthetic polymer and find that the material can loosen bacteria from their moorings, including human tissue and industrial pipes. This discovery could present a new way to design antibiotics, researchers say.

COVID-19 vaccination rates have varied significantly based on partisanship and socioeconomic factors, with Democrats getting vaccinated faster and at higher percentages than Republicans and Independents, according to a University of Michigan study published at NPJ Vaccines.

Gender-diverse college students and students with autism are more likely than their cis peers without autism to experience suicidal thoughts and behaviours, and students who are both gender-diverse and autistic may be the most likely to attempt suicide.
