Nearly two decades after terrorists attacked New York’s World Trade Center, certain cancers are striking police and recovery workers who saved lives, recovered bodies and cleaned up the wreckage.

Living with knee pain? A new study has found that 90% of Americans with osteoarthritis suffer too long before having a knee replacement that could improve their quality of life.
“When people wait too long, they lose more and more function and can’t exercise or be active, thus leaving them open to weight gain, depression and other health problems,” said lead investigator Hassan Ghomrawi, associate professor of surgery at Northwestern University’s Feinberg School of Medicine.

“One of the challenges with educational efforts aimed at getting youth to stop using e-cigarettes or preventing them from starting is that many believe e-cigarettes are harmless,” said study lead author Dr. Thanh-Huyen Vu. She’s a research assistant professor at Northwestern University Feinberg School of Medicine in Chicago.

The findings are “not really surprising,” said Dr. Sabra Abbott, an assistant professor of sleep medicine at Northwestern University’s Feinberg School of Medicine in Chicago. Given the nature of sleep apnea, she said, it makes sense that such changes in the anatomy of the upper airways would improve symptoms.

The new study focuses on a “huge problem,” said Dr. June McKoy, a health services researcher at Northwestern University’s Feinberg School of Medicine in Chicago. Part of the problem may be that it’s very hard to find home healthcare in rural areas for patients finished with post-acute care, McKoy said.

Teresa Woodruff, a professor of obstetrics and gynecology and head of the reproductive science department, commented on Miriam Menkin’s work to cure infertility. “I think she can be really thought of as co-equal with John Rock,” Woodruff says. “Not just a technician or a pair of hands, as people have argued, but actually the intellectual person doing the work.”

Even when women don’t think they need pelvic exams or Pap tests, they should still get annual checkups, said Dr. Melissa Simon of the Northwestern University Feinberg School of Medicine in Chicago, who wrote a commentary accompanying the study.

A recent survey of registered dietitians named the low-carbohydrate keto diet yet again as the most popular diet in the United States. Powering this diet is fat, and loads of it — all the way up to a hefty 90 percent of one’s daily calories.

An initial study using a Google artificial intelligence system suggests the computer predicts breast cancer in mammography scans more accurately that human experts and radiologists. The study from a team of international researchers in the U.S. and U.K. at Google, Deep Mind, Northwestern Medicine, Cancer Research U.K. Imperial Center and the Royal Surrey County Hospital was published in the journal Nature on Wednesday.

Computers that are trained to recognize patterns and interpret images may outperform humans at finding cancer on X-rays.
