Restricted sugar intake during early life is linked to lower risks of several heart conditions in adulthood, including heart attack, heart failure, and stroke, finds a study published by The BMJ using data from the end of UK sugar rationing in 1953. The greatest protection against the risk of developing heart problems—and the longest delay in disease onset—was seen in people whose sugar intake was restricted from conception (in utero) to around 2 years of age.

Illeana Casiano-Vazquez and her husband Sam cherish every minute together. Six years ago, she was diagnosed with triple-negative breast cancer, an aggressive form of the cancer that has fewer treatment options and a higher rate of recurrence. ... Dr. Angela DeMichele, Casiano-Vazquez's oncologist and a professor at the University of Pennsylvania School of Medicine, told CBS News that Casiano-Vazquez had a 25% chance that the breast cancer would come back within five years. DeMichele co-leads a team at Penn conducting a clinical trial that identifies and targets breast cancer "sleeper cells," which are cells that break away from the main tumor and can resurface later to spread cancer throughout the body.

�鶹Ů�� Health News: When A Hearing Aid Isn’t Enough

Kitty Grutzmacher had contended with poor hearing for a decade, but the problem had worsened over the past year. Even with her hearing aids, “there was little or no sound,” she said. “I was avoiding going out in groups. I stopped playing cards, stopped going to Bible study, even going to church.” Her audiologist was unable to offer Grutzmacher, a retired nurse in Elgin, Illinois, a solution. But she found her way to the cochlear implant program at Northwestern University. (Span, 10/23)

The doctors prepared to carry out the brain surgery, their medical tools laid out. Their patient, wide awake on the operating table, was given an instrument of her own: her clarinet, which she began to play. Denise Bacon, 65, blew into the mouthpiece as doctors stood behind her, piercing holes into her skull to implant electrodes that would deliver electrical pulses to the brain in a bid to improve her motor skills. The electrodes were connected to a pulse generator — a device likened to a pacemaker — which sent continuous pulses to modify the brain, helping her manage her symptoms of Parkinson’s disease, for which there is no cure.
