Phenotypes of osteoarthritis: evidence suggests that patients with osteoarthritis fall into multiple phenotypic subgroups defined on the basis of the main driver of disease, one of which is a distinct metabolic phenotype, although all osteoarthritis phenotypes probably involve metabolic alterations; cartilage, bone and synovium are all affected by external and internal drivers of disease such as inflammation, injury or biomechanical alterations, metabolic reprogramming and immunomodulation, but different synovial joint tissues dominate the disease in different patients with osteoarthritis.

Most previous attempts at creating a womb-like device used artificial pumps to drive the blood through the system, causing heart failure. In the system invented by Partridge et al, the fetal heart is the only pump. It is different in other key ways. Use of the bag, rather than a more open container, nearly eliminated the infection issues that contributed to previous failures. And while previous attempts relied on blood vessels in the neck, the authors figured out how to quickly and successfully insert tubes (cannulas) into the notoriously touchy umbilical vessels.

This is an image to demonstrate visual ‘crowding’ and test peripheral vision. Ensure that the red dot in the center of the image is at eye level and focus on it. While holding your focus on the red dot, try to read the middle ‘C’ in every triplet. Is the gap facing left or right? You may find it easier to read in some directions than others. People usually find it easier to read below the dot than above, and easier still to the left or right. Image credit: John Greenwood, University College London.
