Using the nose to treat damaged knees Researchers are now reporting they have successfully harvested cartilage cells from patients’ own noses to produce cartilage transplants for treating bum knees in 10 adults. All the patients had cartilage that was damaged by injury. Two years after reconstruction, most recipients reported improvements in pain, knee function and quality of life. They also developed repair tissue in their knees that was similar in composition to native cartilage. R...
Grab some ginger ale A new study is suggesting that oral perceptions of coldness and carbonation may help to reduce thirst. Because thirst and its cessation contribute to how much fluid a person drinks, the current findings could help guide sensory approaches to increase fluid intake in populations at risk for dehydration, such as older adults. Hopefully, this study will help lead to improved beverage choices for older adults. Drinking fluids helps protect against dehydration, which occurs when...
