Who this helps: This helps patients in aged care and their families by aiming to improve their quality of care.

Plain English
This study looked into tools that can help identify people with Crohn's disease who are at a higher risk of having severe symptoms. The researchers found that the tools being tested, IBDX and PredictSURE-IBD, lacked solid evidence to support their effectiveness, and standard treatment methods (the 'step-up' strategy) were shown to be more cost-effective than advanced testing strategies (the 'top-down' approach).

Plain English
This study examined the role of a protein called calcineurin in how animals learn and adapt to new information, specifically looking at memory tasks that involve changing behaviors. Researchers found that blocking calcineurin made it easier for animals to learn new spatial tasks and harder for them to shift away from previously learned behaviors. In particular, a drug called cyclosporine A showed that reducing calcineurin activity improved learning while also making it challenging to switch to new actions after learning something different. Who this helps: This research could benefit patients with memory impairments and those undergoing therapy for behavioral conditions, as it may lead to better approaches for modifying unwanted behaviors.

Plain English
This study looked at mice with a gene mutation (RCAN1) related to some human neurological disorders to see how it affects their anxiety and stress hormone levels.
