Osteoarthritis isn’t just about aging joints; it's a systemic disorder with metabolic dysfunction and immune activation. PMID:41339496, Nat Rev Rheumatol 2025, @NatRevRheumatol https://doi.org/10.1038/s41584-025-01332-8 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Osteoarthritis as a systemic disease | Nature Reviews Rheumatology
Osteoarthritis (OA) is a painful disorder of the synovial joints characterized by dysfunctional cellular metabolism and extracellular matrix degradation that activates maladaptive repair responses, including pro-inflammatory pathways of innate immunity. OA has historically been viewed as an unavoidable consequence of ageing owing to wear-and-tear of the joint. Most strategies to mitigate OA have primarily focused on the articular cartilage and, more recently, other specific joint tissues, which limits understanding of OA as a systemic disease beyond the joint. Preclinical and clinical data support a paradigm shift in understanding OA as a disease of the whole person, focusing on changes throughout the body that both promote and are caused by OA. This shift provides novel insights into why preclinical research findings have not been successfully translated into clinical therapies. Moreover, a viable strategy for OA drug development could be to treat pain separately from OA structural da

Labor promised to end income control at the last election. Instead, they teamed up with the Coalition to effectively extend it and to enable future governments to expand it without the need for further legislation.

The Greens are now the only party fighting to end income control.
Labor axed cashless debit card... and renamed it the SmartCard. Almost 30k people on compulsory income control at end of its term, Indue receiving another $21m, consultations reject "humiliating" and "suffocating" policy. Dutton could do what he wanted. www.thesaturdaypaper.com.au/news/politic...

I’ve read several articles today referring to RFK Jr. or Geier as vaccine “skeptics”. I again beg the media to STOP SPREADING MISINFORMATION. They are not skeptics. They are lying, grifting, unqualified frauds who are promoting a conspiracy.

“Conspiracy theorists” would be much more accurate.
