Try these 4 things for healthier knees - The Washington Post

Knee health is influenced by several factors, including age, genetics, previous injuries, muscle strength and activity levels, say experts. Phot/ ANIUpdated on: 15 Oct 2026, 2:56 pm3 min readKnee pain is often brushed off as a part of getting older, or blamed entirely on a few extra kilos. The truth, however, is a little more complicated, and understanding it can help you protect your knees at any age. We spoke to an orthopaedic surgeon and a rheumatologist about how body weight and ageing affect the knees, what else plays a role, and which habits can keep joints moving well for longer. How body weight affects your knees“Although body weight is acknowledged as an important element in determining the health of the knees, the impact it has will vary according to factors such as a person’s age, muscle capacity, activity level as well as any health issues that may exist at an earlier stage,” says Dr. Sushil Sharma, Sr. Consultant (Joint & Knee Replacement Surgeon), Kailash Hospital, Noida.

Neutrophils are white blood cells that form part of the body's first line of defence. Researchers have now demonstrated for the first time that neutrophils are found in many tissues during embryonic development, and that they can perform the same functions as adult neutrophils. The findings warrant further study on the role of embryonic neutrophils in tissue development and in responding to infections in fetuses and newborns. Neutrophils are part of innate immune defence. When inflammation occurs, they rapidly migrate from the bloodstream into tissues to eliminate harmful microbes. Their role is well understood in adults, but remarkably little is known about embryonic neutrophils.

The meeting covered several topics in eye care, including how artificial intelligence (AI) can play a part in eye care. The AAO 2026 annual meeting, held in New Orleans, Louisiana, from October 10 to October 12, 2026, was a weekend that provided eye care professionals an opportunity to learn how health care changes are affecting eye care. With the growing use of artificial intelligence (AI) in health care, AI was a particular touching point throughout the meeting, but also notably in how it could help in addressing the equity in eye health. During a session held on October 11, Grayson W. Armstrong, MD, MPH, Director of Ophthalmology Emergency Services at Mass General Brigham, gave a presentation on how AI could be used to advance health equity in ophthalmology, primarily using case studies to demonstrate its usefulness. Armstrong talked about how he had previously done fellowships in telemedicine and medical retina. “And in doing all those things in a city like Boston, you would assume that there are enough doctors and enough technology to tackle the health disparities that come our way,” he said.

Urban residents with more greenery within 100 meters of their homes have a lower risk of developing dementia over time. This is the finding of a new study from Stockholm University and Karolinska Institute, which followed nearly 3,000 older adults for 16 years. Published in the journal Alzheimer's & Dementia, the study highlights the importance of greenspace in the immediate surroundings of the home for sustainable urban planning that supports brain health. The study results show that more greenery in the immediate residential environment is associated with a 20 per cent lower risk of developing dementia over time.
