People with hip and knee osteoarthritis are advised to wear “appropriate footwear” to minimize their pain. Does that mean heels are out? Does it matter if you wear runners or something a little stiffer? How about using insoles?

Cervical cancer rates are plummeting in states with higher rates of HPV vaccination, a new study reports. Overall, cervical cancers have declined by 27% among young women in the years since the human papillomavirus (HPV) vaccine became available in the United States, researchers report in the Journal of the National Cancer Institute.

A key goal in aging research is not just to extend life, but to ensure more people live longer and healthier lives with less variation in age at death, a concept known as “squaring the survival curve.” Using a recent meta-analysis, Dr. Tahlia Fulton and Associate Professor Alistair Senior from the University of Sydney School of Life and Environmental Sciences have re-examined how dietary restriction and two related drugs, rapamycin and metformin, affect variation in age at death in vertebrates.

The findings suggest that changes in average cannabis use among young people are reflected across the entire group—from those who use it infrequently to those who use it frequently.

On average, telemedicine patient visits were billed $400 less, and they also resulted in fewer follow-up visits after the initial appointment. The analysis is published in JAMA Network Open.
