NEW PROSTATE CANCER SURGERY PRESERVES ERECTILE FUNCTION A technique designed to improve the precision of prostate cancer surgery almost doubles the odds of preserving a man’s erectile function compared to standard surgery, according to a study published in The Lancet Oncology. Surgery often results in
erectile dysfunction and urinary incontinence, but the new method, called NeuroSAFE, preserves the nerves in the prostate’s outer layers, which are believed to be responsible for producing erections. The new technique includes
a test to ensure that all cancerous cells are removed, so that preserving the nerves doesn’t risk leaving cancerous cells behind. In a study of men with prostate cancer who underwent prostate removal, 39% of those who had the NeuroSAFE procedure had no or only mild erectile dysfunction compared to 23% of those who had standard surgery. “It is an involved procedure
Just a single hour of screen use in bed increases the risk of insomnia by 59%, and reduces sleep time by 24 minutes, according to research published in Frontiers in Psychiatry. “The type of screen activity does not appear to matter as much as the overall time spent using screens in bed,” said Gunnhild Johnsen Hjetland,

that requires expertise, but it isn’t expensive, particularly given the benefits it offers for patients, and most importantly doesn’t jeopardize cancer control,” said Greg Shaw, M.D.
ONE HOUR OF SCREEN TIME IN BED INCREASES INSOMNIA
Scientists at the University of Ottawa found that plunging into an icy bath may slow aging.
Healthy men underwent
cold-water immersion at 57.2 degrees Fahrenheit for one hour for seven consecutive days.
Blood samples were
collected before and after immersion. The cold plunges affected
autophagic function, which is the recycling of healthy cells, as well as apoptotic function, the programmed cell death that gets rid of damaged cells. “Our findings indicate
that repeated cold exposure significantly improves autophagic function, a critical cellular protective mechanism,” said Glen Kenny, Ph.D. “This enhancement allows
cells to better manage stress and could have important implications for health and longevity.” Lead author Kelli King
noted, “Cold exposure might help prevent diseases and potentially even slow down aging at a cellular level. It’s like a tune-up for your body’s microscopic machinery.”
HIGH-SALT DIET LINKED TO DEPRESSION Research has shown

that a high-salt diet (HSD) contributes to depression, and a recent animal study uncovered the reason for this link. High-salt diets spur the
production of a protein called IL-17A, which is known to contribute to depression in humans. After being fed an HSD
for five weeks, mice showed increased levels of IL-17A along with depression-like symptoms.
But when mice that
couldn’t produce IL-17A were fed an HSD, their mood wasn’t affected, correlating with human studies connecting low-salt diets with positive moods. The study was published in The Journal of Immunology.
SHINGLES VACCINE MAY LOWER DEMENTIA ODDS A Stanford Medicine study found that older adults who received the shingles vaccine were 20% less likely to develop dementia. People who got the vaccine not only reduced their odds of getting shingles by
37% during the seven-year study, but also those who turned 86
and 87 at the end of the study period were 20% less likely to develop dementia than the unvaccinated. “It was a really striking finding,” said Pascal Geldsetzer, M.D., Ph.D. “This huge protective signal was there, any which way you looked at the data.” Results were published in Nature.
